INTRODUCTION

Company overview

ArcelorMittal is one of the world's leading integrated steel and mining companies. ArcelorMittal is the largest steel producer in Europe and among the largest in the Americas, and a growing presence in Asia including India through its joint venture AMNS India.

*Iron ore production includes production from ArcelorMittal Mining Canada G.P. and ArcelorMittal Infrastructure G.P. ("AMMC"), ArcelorMittal Liberia and captive mines.

ArcelorMittal has steel-making operations in 15 countries, including 36 integrated and mini-mill steel-making facilities. As of December 31, 2024, ArcelorMittal had approximately 125,416 employees.

ArcelorMittal produces a broad range of high-quality finished and semi-finished steel products ("semis"). Specifically, ArcelorMittal produces flat products, including sheet and plate, and long products, including bars, rods and structural shapes. It also produces pipes and tubes for various applications. ArcelorMittal sells its products primarily in local markets and to a diverse range of customers in approximately 129 countries, including the automotive, appliance, engineering, construction and machinery industries. ArcelorMittal's mining operations produce various types of mining products including iron ore lump, fines, concentrate, pellets and sinter feed.

As a global steel producer, the Company is able to meet the needs of different markets. Steel consumption and product requirements clearly differ between developed markets and developing markets. Steel consumption in developed economies is weighted towards flat products and a higher value-added mix, while developing markets utilize a higher proportion of long products and commodity grades. To meet these diverse needs, the Company maintains a high degree of product diversification and seeks opportunities to increase the proportion of higher value-added products in its product mix.

History and development of the Company

ArcelorMittal results from the merger in 2007 of its predecessor companies Mittal Steel Company N.V. and Arcelor, each of which had grown through acquisitions over many years. Since its creation ArcelorMittal has experienced periods of external growth as well as consolidation and deleveraging (including through divestment).

ArcelorMittal's success is built on its core values of safety, sustainability, quality and leadership and the entrepreneurial boldness that has empowered its emergence as the first truly global steel and mining company. Acknowledging that a combination of structural issues and macroeconomic conditions will continue to challenge returns in its sector, the Company has adapted its footprint to the new demand realities, redoubled its efforts to control costs and repositioned its operations with a view toward outperforming its competitors. ArcelorMittal's research and development capability is strong and includes several major research centers as well as strong academic partnerships with universities and other scientific bodies.

Against this backdrop, ArcelorMittal's strategy is to leverage four distinctive attributes that will enable it to capture leading positions in the most attractive areas of the steel industry's value chain, from mining at one end to distribution and firststage processing at the other: global scale and scope; superior technical capabilities; a diverse portfolio of steel and related businesses, one of which is mining; and financial capabilities. The Company's strategy is further detailed under "Business overview—Business strategy".

ArcelorMittal's steel-making operations have a high degree of geographic diversification. In 2024, approximately 38% of its crude steel was produced in the Americas, approximately 53% was produced in Europe and approximately 9% was produced in other countries, such as South Africa and Ukraine. In addition, ArcelorMittal's sales of steel products are spread over both developed and developing markets, which have different consumption characteristics. ArcelorMittal's mining operations, including captive mines are present in North America, South America, Africa and Europe. Captive mines are integrated into the Company's global steel-making facilities.

Competitive strengths

The Company believes that the following factors contribute to ArcelorMittal's success in the global steel and mining industry:

Market leader in steel. ArcelorMittal had annual achievable production capacity of approximately 76.7 million tonnes of crude steel for the year ended December 31, 2024. Steel shipments for the year ended December 31, 2024 totaled 54.3 million tonnes. ArcelorMittal has significant operations in many countries which are described in "Properties and capital expenditures". In addition, many of ArcelorMittal's operating units including through its joint ventures have access to developing markets that are expected to experience, over

time, above-average growth in steel consumption (such as Central and Eastern Europe, South America, India, Africa and Southeast Asia).

The Company sells its products in local markets and through a centralized marketing organization to customers in approximately 129 countries. ArcelorMittal's diversified product offering, together with its distribution network and research and development ("R&D") programs, enable it to build strong relationships with customers, which include many of the world's major automobile and appliance manufacturers. The Company is a strategic partner to many major original equipment manufacturers ("OEMs") and has the capability to build long-term contractual relationships with them based on early vendor involvement, contributions to global OEM platforms and common value-creation programs.

A world-class mining business. ArcelorMittal has a global portfolio of 9 operating units with mines in operation and development and is among the largest iron ore producers in the world. In 2024, ArcelorMittal sourced a large portion of its raw materials from its own mines and facilities including leases. The table below reflects ArcelorMittal's self-sufficiency through its mining operations in 2024.

Millions of metric tonnes	Consumption	Sourced from own mines/ facilities2	Self sufficiency %
Iron ore	71.1	40.9	58%
PCI & coal1	27.6	—	—%
Coke	16.7	15.0	90%
Scrap & DRI	25.3	13.6	54%

1. Includes coal only for the steelmaking process and excludes steam coal for power generation. ArcelorMittal's consumption of PCI and coal was 6.3 million tonnes and 21.3 million tonnes, respectively, for the year ended December 31, 2024.

2. Assumes 100% consumption of ArcelorMittal's iron ore and coal shipments.

The Company has iron ore mining activities in Brazil, Bosnia, Canada, Liberia, Mexico, Ukraine, South Africa and through its joint venture in India and associate in Canada (Baffinland). ArcelorMittal's main mining products include iron ore lump, fines, concentrate, pellets and sinter feed. In addition, ArcelorMittal produces substantial amounts of DRI, an important metallic feedstock required for the production of highest quality steels through the EAF route, which will grow substantially in the context of decarbonization. As of December 31, 2024, ArcelorMittal's iron ore reserves (including reserves at mines where ArcelorMittal owns less than 100%, based on ArcelorMittal's ownership percentage even if ArcelorMittal is entitled to mine all the reserves, and including reserves for which use is restricted) were estimated at 3,831 million tonnes run of mine. See "Properties and capital expenditures—Mineral reserves and resources" for a detailed list of the entities with mineral reserves and resources and ownership structure. The Company's long-life iron ore reserves and resources provide a measure of security of supply and an important natural hedge against raw material volatility and global supply constraints. The seaborne iron ore

mining business is managed as a separate segment which enhances ArcelorMittal's ability to optimize capital allocation.

ArcelorMittal's facilities have good access to shipping facilities, including through ArcelorMittal's own, or partially owned, 18 deep-water port facilities and linked railway sidings.

Market-leading automotive steel business. ArcelorMittal has a leading market share (approximately 16% of the worldwide market) in automotive, and is a leader in the fastgrowing advanced high-strength steels ("AHSS") segment, specifically for flat products. ArcelorMittal is the first steel company in the world to embed its own engineers within an automotive customer to provide engineering support. The Company begins working with OEMs as early as five years before a vehicle reaches the showroom, to provide generic steel solutions, co-engineering and help with the industrialization of the project. These relationships are founded on the Company's continuing investment in R&D and its ability to provide well-engineered solutions that help make vehicles lighter, safer and more fuel-efficient.

In 2024, ArcelorMittal continued to extend the S-in Motion® catalog according to the automotive market trends. The S-in Motion® battery electric vehicles ("BEV") catalog of steel solutions has been adapted to include specific products for BEV's including new designs focused on battery protection. Advanced and especially ultra-high strength steels, innovative press hardened steels, and laser welded blanks are especially highlighted as key solutions for optimal performance (passenger safety/lightweighting) and battery protection. The growth of various types of electric vehicles will impact design and manufacturing leading to demand for different materials and steel grades, and more AHSS for battery protection. For instance, both the battery box and body structure have to protect the battery in the event of a crash.

In the automotive industry, ArcelorMittal mainly supplies the geographic markets where its production facilities are located, which are Europe, North and South America, South Africa, India through its joint venture AMNS India, and China through Valin ArcelorMittal Automotive Steel Co., Ltd ("VAMA"), a joint venture with Hunan Valin. VAMA's product mix is oriented toward higher value products and mainly toward the OEMs to which the Company sells tailored solutions based on its products. With sales and service offices worldwide and production facilities in North and South America, South Africa, Europe, India and China, ArcelorMittal believes that it is uniquely positioned to supply global automotive customers with the same products worldwide. The Company has multiple joint ventures and has also developed a global downstream network of partners through its distribution solutions activities. This provides the Company with a proximity advantage in virtually all regions where its global customers are present.

Sustainability (with focus on CO2 emission reduction in the supply chain) has become a key requirement in the automotive industry linked to the importance of sustainability in the holistic electrical vehicle market. In 2021, ArcelorMittal launched two solutions under the XCarb® brand: XCarb® green steel certificates and XCarb® recycled and renewably produced ("RRP"), which was well received in automotive industry and markets. The first XCarb® RRP steels were successfully launched in Europe and in North America, exhibiting potential for reduction in CO2 emissions. ArcelorMittal also combines manufacturing simplification and sustainability with the development in Europe of the XCarb® Door Ring.

For further details on the new products under development, see "Business overview—Research and development".

Diversified and efficient producer. As a global steel manufacturer with a leading position in many markets, ArcelorMittal benefits from scale and production cost efficiencies in various markets and a measure of protection against the cyclicality of the steel industry and raw materials prices.

• Diversified production process. In 2024, approximately 43.5 million tonnes of crude steel were produced through the basic oxygen furnace process ("BOF") and approximately 14.4 million tonnes through the electric arc furnace ("EAF") process. This provides ArcelorMittal with greater flexibility in its raw material and energy use, and increased ability to meet varying customer requirements in the markets it serves.
• Product and geographic diversification. By operating a portfolio of assets diversified across product segments and geographic areas, ArcelorMittal benefits from a number of natural hedges. As a global steel producer with a broad range of highquality finished and semi-finished steel products, ArcelorMittal is able to meet the needs of diverse markets. Steel consumption and product requirements vary between mature economy markets and developing economy markets. Steel consumption in mature economies is largely from flat products and a higher value-added mix, while developing markets utilize a higher proportion of long products and commodity grades. As developing economies mature and markets evolve, local customers will require increasingly advanced steel products. To meet these diverse needs, ArcelorMittal maintains a high degree of product diversification and seeks opportunities to increase the proportion of its product mix consisting of higher value-added products.
• Upstream integration. ArcelorMittal believes that its own raw material production provides it with a competitive advantage over time. Additionally, ArcelorMittal benefits from the ability to optimize its steel-making facilities' efficient use of raw materials, its global procurement strategy and the

implementation of Company-wide knowledge management practices with respect to raw materials. Certain of the Company's operating units also have access to infrastructure, such as deep-water port facilities, railway sidings and engineering workshops that lower transportation and logistics costs.

• Downstream integration. ArcelorMittal's downstream integration, primarily through its Europe segment for distribution solutions, enables it to provide customized steel solutions to its customers more effectively. The Company's downstream assets have cut-to-length, slitting and other processing facilities, which provide value additions and help it to maximize operational efficiencies.

Dynamic responses to market challenges and

opportunities. ArcelorMittal's management team has a strong track record and extensive experience in the steel and mining industries.

In February 2022, the Company announced a new three-year \$1.5 billion value plan (\$1.4 billion scope adjusted for the sale of ArcelorMittal Temirtau operations on December 7, 2023) focused on creating value through well-defined commercial and operational initiatives. This plan did not include the impact of strategic capital expenditure projects (which are followed separately). The plan includes commercial initiatives, including volume/mix improvements and operational improvements (primarily in variable costs). The plan aims at protecting operating income potential of the business from rising inflationary pressures, improving its relative competitive position vis-à-vis its peers and supporting sustainably higher profits. The plan was completed in 2024, and the actions taken in the three years from 2022 to 2024 have yielded cumulative benefits of \$1.4 billion (approximately 100% of the scope adjusted target). These include \$0.4 billion of commercial initiatives, \$0.7 billion of variable costs savings and \$0.2 billion of logistic and other improvements.

Proven expertise in acquisitions

ArcelorMittal's management team has proven expertise in successfully acquiring and subsequently integrating operations. The Company takes a disciplined approach to investing and uses teams with diverse areas of expertise from different business units across the Company to evaluate opportunities, conduct due diligence and monitor integration and post-acquisition performance. The Company introduces focused capital expenditure programs, implements Companywide best practices, balances working capital, ensures adequate management resources and introduces safety and environmental improvements at acquired facilities. ArcelorMittal believes that these operating and financial measures have improved the operating performance and the quality of steel produced at such facilities.

In recent years, the Company has focused on portfolio optimization including assets disposals and strategic M&A activity (see also "— Key transactions and events in 2024"). In 2022, ArcelorMittal acquired a 80% interest in voestalpine's world-class Hot Briquetted Iron ("HBI") plant in Texas and in 2023, the Company completed the acquisition of Companhia Siderúrgica do Pecém ("CSP") renamed ArcelorMittal Pecém in Brazil, a world-class operation, producing high-quality slab at a globally competitive cost. To further support its decarbonization strategy, ArcelorMittal acquired several steel recycling businesses (ALBA and John Lawrie Metals in 2022, Riwald Recycling in 2023). It also complemented the Company's existing geographic presence and strengthened the product portfolio of the Sustainable Solutions segment's construction business through the acquisitions of Italpannelli Germany, Spain and Italy in 2023 and 2024. In August 2024, ArcelorMittal acquired a 28% stake in Vallourec, which presents a compelling opportunity to increase the Company's exposure to the attractive, downstream, value-added tubular market.

Sustainability leadership

ArcelorMittal is committed to the industry's efforts to decarbonize, and to being part of the solution to the world reaching net-zero by 2050. As innovation is central to the Company's success given the onus it places on research and development ("R&D") with the goal of ensuring ArcelorMittal is at the forefront of the evolution of steelmaking processes and products, the Company has developed the industry's broadest and most flexible suite of low-emissions steelmaking technologies and has integrated them into two pathways, Smart Carbon and Innovative-DRI, both of which hold the potential to deliver carbon-neutral steelmaking.

Key transactions and events in 2024

During 2024, ArcelorMittal completed several financing and liability management transactions. Please refer to "Operating and financial review—Liquidity and capital resources— Financings" of this report for a summary of these transactions.

• On February 20, 2024, the Italian government placed Acciaierie d'Italia SpA ("ADI") into extraordinary administration proceedings ("EA") subsequent to the request of Invitalia, thereby passing control of the company from its then current indirect shareholders, ArcelorMittal and Invitalia, and management to government-appointed commissioners. Shortly thereafter, the court of Milan ascertained ADI's insolvency, thereby definitively confirming the EA proceeding. As a result, ArcelorMittal has been stripped of its rights as an indirect shareholder of ADI. Similarly, ArcelorMittal has been stripped of its rights as a direct shareholder in ADI's parent company, Acciaierie d'Italia Holding S.p.A. ("ADIH"), after the Italian government placed it in EA. This ended ArcelorMittal's involvement in ADI, which dated back to 2018 (then ADI was known as Ilva). During its involvement, ArcelorMittal had been fully committed to the people and assets of ADI, investing over €2 billion in the business since 2018. See "Risk Factors and Control— ArcelorMittal is currently, and in the future may be, subject to legal proceedings or other proceedings, including in relation to its interest in ADI, the resolution of which could negatively affect the Company's profitability and cash flows in a particular period."
• On March 19, 2024, ArcelorMittal announced that Kleber Silva was nominated as Executive Vice President of ArcelorMittal and appointed as Chief Executive Officer of ArcelorMittal Mining, effective April 8, 2024. See "Management and employees—Directors and senior management—Senior management".
• On May 31, 2024, ArcelorMittal completed the acquisition of Italpannelli SRL in Italy and Italpannelli Iberica in Spain. This marks the second acquisition of Italpannelli businesses by ArcelorMittal, following the purchase of Italpannelli Germany near Trier in March 2023. Italpannelli is a manufacturer of lightweight insulation panels for roofs and façades. It operates two production plants across Europe, in Zaragoza (Spain) and Abruzzo (Italy). Combined the two facilities operate seven production lines with a capacity of 13 million square meters of sandwich panels per year, primarily serving customers in

the central and eastern European, Italian and Spanish markets and employ approximately 260 people.

• On November 28, 2023, ArcelorMittal South Africa announced the contemplated wind down of its Newcastle works and the broader long steel products business ("Longs Business"), subject to the results of a due diligence and a consultative process involving key customers, suppliers, organized labor and other stakeholders, including the South African government. On July 2, 2024, ArcelorMittal South Africa announced that the Longs Business would continue to operate to allow an opportunity for the short-, medium- and longer-term initiatives (aimed at securing its sustainability) to be fully explored. ArcelorMittal worked extensively with the South African government and stakeholders to explore alternatives for sustaining the Longs Business. While not seeking subsidies, ArcelorMittal South Africa requested policy support to address structural constraints affecting the steel sector. Despite extensive consultations with the South African government and stakeholders to find viable solutions to sustain the Longs Business, progress was insufficient and a decision was made to wind down the Longs Business. Such decision comes after sustained challenges, including weak economic growth, high logistics and energy costs, and an influx of low-cost steel imports, particularly from China, combined with insufficient policy interventions (especially longstanding policy decisions (namely, the Price Preference System (PPS) and Export Scrap tax) relating to the substantial subsidization of scrap-based steelmaking operations to the detriment of the Newcastle Works – which benefits South African-sourced raw materials). On January 6, 2025, ArcelorMittal South Africa announced that it will transition the Longs Business into care and maintenance subject to a consultation process. The persistent overcapacity in the global and local markets, and unsustainably low international steel prices have further exacerbated the business' structural difficulties. Asset utilization in the Longs Business reached only 50% as weak market conditions necessitated the operation of its blast furnace at the lowest level technically and responsibly possible. It is expected that approximately 3,500 direct and indirect jobs will be affected. Steel production was anticipated to cease by late January 2025, with the wind-down of the remaining production processes completed in the first quarter of 2025 but the wind-down was postponed for one additional month as discussions continued regarding potential governmental support. On February 28, 2025, ArcerlorMittal South Africa announced that it will implement the final wind down of the Longs Business. It is envisaged that the shutdown of the blast furnaces will commence in the first week of March, with the last steel produced in late-March or early-April 2025. The final wind down into care and maintenance will be fully implemented in the second quarter of 2025.

• • On August 6, 2024, ArcelorMittal completed the acquisition of 65,243,206 shares, representing approximately 28.4% non-controlling equity interest in Vallourec, for €14.64 per share from Funds managed by Apollo Global Management, Inc., for a total consideration of €960 million (\$1,048 million). Having carried out a successful restructuring in recent years, the Company believes Vallourec presents a compelling opportunity to increase ArcelorMittal's exposure to the attractive, downstream, value-added tubular market. Vallourec is a global leader in premium tubular solutions for energy markets and demanding industrial applications, offering innovative, safe and competitive products for various sectors including energy, automotive and construction. Approximately 85% of Vallourec's 2.2 million tonnes of annual rolling capacity is focused around low-carbon, integrated productions hubs in the United States and Brazil, both of which are important strategic markets for ArcelorMittal.
• On October 11, 2024, ArcelorMittal announced it had entered into a definitive Equity Purchase Agreement (the "Agreement") with Nippon Steel Corporation ("NSC") pursuant to which ArcelorMittal will purchase NSC's 50% equity interest in the AMNS Calvert joint venture (the "Transaction"). The Transaction was entered into at the request of NSC to address regulatory concerns pursuant to its entry into an agreement to acquire US Steel. The Transaction is subject to NSC completing its pending acquisition of US Steel, which is subject to various other regulatory requirements. Under the terms of the agreement, ArcelorMittal will pay \$1 consideration for the Transaction; further, NSC will inject cash and forgive partner loans in an amount estimated to be approximately \$0.9 billion. On January 3, 2025, the U.S. President issued an order prohibiting NSC from acquiring US Steel but the parties were granted an extension to June 18, 2025 to permanently abandon the transaction. The agreement with NSC remains in place until such date.

Sustainable development highlights

• On February 27, 2024, ArcelorMittal announced that it had signed a memorandum of understanding with Petrobras to assess potential business models for lowcarbon fuels, hydrogen and its products, renewable energy production and carbon capture and storage

("CCS"). This follows a joint study to develop a CCS hub in the state of Espirito Santo.

• On April 22, 2024, ArcelorMittal announced that ArcelorMittal Calvert, wholly owned by ArcelorMittal, was planning for an advanced manufacturing facility in Calvert, Alabama that could deliver up to 150,000 tonnes of domestic production capacity of non-grain-oriented electrical steel ("NOES") annually, depending on the product mix. NOES plays a crucial role in the performance and efficiency of electric motors used to power battery electric vehicles, plug in hybrid electric vehicles and hybrid vehicles as well as other specialized commercial, industrial, and power generation applications. Given the nature of the US auto market (larger vehicles, full-size pickups, SUVs) there is rapidly growing demand for the most sophisticated NOES for which there is limited US domestic supply capabilities. Plans at ArcelorMittal Calvert include an annealing pickling line, cold-rolling mill, annealing coating line, packaging and slitter line, and ancillary equipment needed for operations. The planned investment is expected to create up to 1,300 jobs during the construction phase and more than 200 permanent positions to support the plant's ongoing operations. The NOES facility would be sited near ArcelorMittal's existing joint venture with Nippon Steel Corporation AMNS Calvert. On February 6, 2025, ArcelorMittal confirmed that it will proceed with the construction of the facility with estimated net capital expenditure of \$0.9 billion (net of \$0.3 billion of currently planned federal, state and local support). The plant is anticipated to commence production in the second half of 2027.
• On May 10, 2024, ArcelorMittal announced that it had started the construction of an EAF for long products at its Gijón plant, which is expected to produce its first heat in the first quarter of 2026. This investment of €213 million will be the first major EAF project to be implemented within the Company's decarbonization program in Europe and will constitute the first step towards low-carbon emissions steelmaking in Asturias. The new facility will have an annual production capacity of 1.1 million tonnes of semi-finished steel products, which will be supplied to the rail and wire-rod mills at the plant. Initially, steel production through the new EAF will lead to a reduction in CO2 emissions of over 35%; the reduction in emissions could reach 1 million tonnes of CO2 equivalent a year once the transition phase has been completed.
• On May 21, 2024, ArcelorMittal announced that it had successfully started operating a pilot carbon capture unit on the blast furnace off-gas at ArcelorMittal Gent in Belgium with partners Mitsubishi Heavy Industries, Ltd. (MHI), BHP, along with Mitsubishi Development Pty Ltd (Mitsubishi Development). The pilot carbon capture unit will operate for one to two years at Gent, to test the feasibility of progress to full-scale deployment of the

technology, which would be able to capture a sizeable portion of the Gent site emissions, if successful.

• On August 21, 2024, ArcelorMittal Brasil signed contracts for the development of two solar energy projects with a combined capacity of 465MW, equivalent to 14% of its current electricity requirements. The first project builds on ArcelorMittal Brazil's existing relationship with Casa dos Ventos (see "Properties and capital expenditures— Investments in joint ventures—Ventos de Santo Antonio"). This latest agreement – again a joint venture in which ArcelorMittal Brazil will hold a 55% stake with Casa dos Ventos holding the balance – will see the construction of a 200MW capacity solar power plant on the same site as the wind power project, in the state of Bahia, north-east Brazil, with commissioning also expected before the end of 2025. The second project is a partnership with Atlas Renewable Energy, the second largest independent renewable energy developer in Latin America, for the development of a 265MW capacity solar energy project in the state of Minas Gerais, east Brazil. The agreement is for an initial 50/50 joint venture, with ArcelorMittal acquiring 100% of the solar park upon build completion. Project commissioning is again expected before the end of 2025. Both projects are subject to approval from the Administrative Council for Economic Defense (CADE), Brazil's antitrust authority. The projects support ArcelorMittal Brazil's aims to secure and decarbonize its future electricity needs and are a further step towards its long-term ambition to be self-sufficient in terms of its electricity requirements.

Risk factors

ArcelorMittal's business, financial condition, results of operations, reputation or prospects could be materially and adversely affected by one or more of the risks and uncertainties described below.

I. Risks related to the global economy and the mining and steel industry

Prolonged low steel and (to a lesser extent) iron ore prices, low steel demand and/or steel/iron ore oversupply would have an adverse effect on ArcelorMittal's results of operations.

As an integrated producer of steel and iron ore, ArcelorMittal's results of operations are sensitive to the market prices of, and demand for, steel and iron ore in its markets and globally. The impact of market steel prices on its results is direct while the impact of market iron ore prices is both direct and indirect, as ArcelorMittal sells iron ore on the market to third parties (in which case it benefits from higher iron ore market prices), and indirect, as iron ore is a principal raw material used in steel production and fluctuations in its market price are typically and eventually (with the timing dependent on steel market conditions) passed through to steel prices (with any lags in

safety audit that was commissioned at the end of 2023, against the backdrop of a clear necessity to strengthen Group safety performance. The audit, which was ongoing for nine months across all geographies, functions and levels of the organization, had three main scopes: (i) fatality prevention standards for the three main occupational risks leading to serious injuries and fatalities (work at heights, vehicle driving and energy isolation); (ii) process safety management focused on the highest risk assets; and (iii) in-depth assessments of health and safety (H&S) systems, processes and capabilities; governance and assurance processes; and data management. See "Business overview—Sustainability development—Health and Safety.".

• On November 26, 2024, ArcelorMittal provided an update on its decarbonization plans in Europe. See "Business overview—Sustainability development—Climate change and decarbonization".

Risk Factors and Control

passing on higher prices "squeezing" steel margins, as discussed below). Steel and iron ore prices are affected by supply and demand trends and inventory cycles. In terms of demand, steel and iron ore prices are sensitive to trends in cyclical industries, such as the automotive, construction, appliance, machinery, equipment and transportation industries.

More generally, steel and iron ore prices are sensitive to macroeconomic fluctuations in the global economy which are impacted by many factors ranging from trade and geopolitical tensions to global and regional monetary policy to specific disruptive events such as pandemics, wars and natural disasters. Prior recessions have generally resulted in lower steel demand and steel prices, with consequential material adverse impacts on steel companies' results. Significant declines in steel prices have resulted, and may in the future result, in inventory-related charges. In addition, the impact of lower steel prices on ArcelorMittal's results is subject to a lag effect (due to its contracts), and therefore the impact is felt beyond the duration of any decline in spot steel prices. In the past, substantial price decreases during periods of economic

weakness have not always been offset by commensurate price increases during periods of economic strength.

Market prices for iron ore are also affected by supply and demand conditions. Excess iron ore supply relative to demand has led to depressed prices at various points in recent years and could recur, with potentially a corollary effect on steel prices. No assurance can be given that iron ore prices will not decline further, particularly if there is a recession, Chinese steel demand declines, worldwide capacity increases due to new mines coming online or steel demand declines again due, for example, to the negative effects from the continuing Russia-Ukraine and Middle East conflicts, or other regional conflicts, in particular on energy supply and prices.

The steel industry suffers from structural overcapacity globally, especially for long products. This overcapacity is affected by global macroeconomic trends and amplified during periods of global or regional economic weakness, leading to weaker global or regional demand, increased exports and/or decreased regional or global prices. In particular, China is both the largest global steel consumer and the largest global steel producer by a large margin. At various points in the past and since the second quarter of 2024, weaker Chinese steel demand has not been fully offset by reduced Chinese steel production (due to large price gaps compared to markets outside China), which has led to a flood of Chinese steel exports into various regional markets, including the Company's principal markets, weighing on demand and indeed depressing market prices. If this trend persists, it will likely lead to rising inventory levels in steel markets outside of China and continued downward pressure on prices and spreads, negatively affecting the Company's profitability. Exports by steel producers in other developing countries and regions (such as the CIS, Turkey and India) into the Company's principal markets are also a market feature. The extent of these exports depends on the demand/production balance in the producer's home market as well as on regional market pricing differentials (including any applicable import tariffs). The European steel market is particularly sensitive to the import threat due to structural overcapacity, which may also be aggravated by any new or reinstated tariffs (such as those announced in the United States). See "Unfair trade practices, import tariffs and/or, barriers to free trade could negatively affect steel prices and ArcelorMittal's results of operations in various markets".

In terms of inventory, steel stocking and destocking cycles affect apparent demand for steel and hence steel prices and steel producers' profitability. For example, steel distributors may accumulate substantial steel inventories in periods of low prices and, in periods of rising real demand for steel from endusers, steel distributors may sell steel from inventory (destock), thereby delaying the effective implementation of steel price increases. Conversely, steel price decreases can sometimes develop their own momentum, as customers adopt a "wait and see" attitude and destock in the expectation of further price decreases. The trajectory of steel and iron ore

demand and prices going forward, in particular in 2025, is difficult to predict, including given the variables described above. A scenario of prolonged low steel and (to a lesser extent or if simultaneous) iron ore prices, whether or not combined with low steel demand, would have a material adverse effect on ArcelorMittal's results of operations and financial condition. Moreover, a renewed phase of steel and iron ore oversupply would likely have a material adverse effect on ArcelorMittal's results of operations and financial condition.

Volatility in the supply and prices of raw materials, energy and volatility in steel prices or mismatches between steel prices and raw material prices could adversely affect ArcelorMittal's results of operations.

Steel production consumes substantial amounts of raw materials (the prices of which have been highly volatile in recent years) including iron ore, coking coal and coke, and the production of direct reduced iron, the production of steel in EAF and the re-heating of steel involve the use of significant amounts of energy, making steel companies, such as ArcelorMittal, dependent on the price of, and their reliable access to, supplies of raw materials and energy. Although ArcelorMittal has substantial sources of iron ore from its own mines (the Company's self-sufficiency rate was 58% for iron ore in 2024), it remains exposed to volatility in the supply and price of iron ore and coking coal given that it obtains a significant portion of such raw materials under supply contracts from third parties. Industry and overall decarbonization efforts may also result in increased and/or volatile prices, in particular, higher energy and carbon dioxide ("CO2") prices as well as scrap prices (due in particular to an industry shift to EAF production). See ""Business overview— Products—Mining products", "Business overview—Products— Other raw materials and energy" and "Operating and financial review—Key factors affecting results of operations—Raw materials". The compression of steel spreads, including from inflationary cost pressures and negative price-cost effects, has resulted, and may in the future result, in the Company reducing or ceasing production at certain plants. See "Key transactions and events in 2024". Production cuts do not eliminate all costs as the Company still incurs operating costs when production capacity is idled and may incur increased costs to resume production at idled facilities. Idling can also impact the long-term health of assets, despite steps taken to protect them.

Furthermore, while steel and certain raw material (in particular iron ore and coking coal) price trends have historically been correlated, the Company has experienced (particularly in Europe and North America) negative price-cost effects due to differences in steel and raw material price trends (including due to sudden spikes in raw material prices). See "Operating and financial review—Key factors affecting results of operations". The Company is likely to continue to experience such negative effects in the future as this is a structural feature.

ArcelorMittal's other principal input costs that affect its level of profitability are energy and transportation. Energy expenses are sensitive to changes in electricity, energy transportation and fuel prices, including diesel fuel, natural gas and industrial gas. While the Group has some long-term contracts with electrical, natural gas and industrial gas suppliers, it is exposed to fluctuations in electricity, natural gas and industrial gas prices that can fluctuate widely with availability and demand levels from other users. In addition, in certain circumstances (such as periods of peak usage), supplies of energy in general may be curtailed, and the Company may not be able to purchase them at historical rates or at all. Supply disruptions may also cause energy prices to increase, as has occurred previously (and is likely to occur in the future) due to geopolitical conflicts (such as the Russian-Ukraine war and conflicts in the Middle East) and destructions of gas pipelines. Such events and any other significant cuts in energy supplies or a collapse in demand due to supply issues or otherwise have resulted, and may in the future result, in the Company having to cut production regionally or globally. Indirectly, if steel-using customers are unable to source the energy supplies needed for their operations, they will be unable to operate and their demand for steel will decline.

Unfair trade practices, import tariffs and/or barriers to free trade could negatively affect steel prices and ArcelorMittal's results of operations in various markets. ArcelorMittal is exposed to the effects of "dumping" and other unfair trade and pricing practices by competitors. Moreover, government subsidies to the steel industry remain widespread in certain countries, particularly those with centrally controlled economies such as China. In periods of lower global demand for steel, there is an increased risk of additional volumes of unfairly-traded steel exports into various markets, including Europe, North America and other markets such as Brazil and South Africa, in which ArcelorMittal produces and sells its products. Such imports have had and could in the future have the effect of reducing prices and demand for ArcelorMittal's products.

ArcelorMittal is also exposed to the effects of import tariffs, other trade barriers and protectionist policies more generally due to the global nature of its operations. Various countries have instituted, and may institute import tariffs and barriers that could, depending on the nature of the measures adopted, adversely affect ArcelorMittal's business by limiting the Company's access to or competitiveness in steel markets. While such protectionist measures can help the producers in the adopting country, they may be ineffective (or only effective in the short-term), raise the risk of exports being directed to markets where no such measures are in place or are less effective and/or result in retaliatory measures.

The prospect of higher tariffs, protectionist measures, increased trade disputes and retaliatory actions is heightened in 2025 based on recent actions and announcements in various countries, including Brazil, Turkey and India, as well as the changing policies of the new U.S. administration. For

example, in February 2025, the U.S. administration announced new Section 232 tariffs, reinstating a 25% tariff on all steel imports as from March 2025. Export sales of steel products from the Company to the U.S. market represented \$6.7 billion in 2024. As was the case in 2018, new retaliatory protectionist measures may be announced in the European Union, Canada or in other countries as a result. The imposition of tariffs (whether in the United States or in other countries or regions) may in the short term, pending increases in domestic production, result in higher steel prices (enabling ArcelorMittal's exports from Canada and Mexico into the U.S. to remain competitive and profitable) and/or increase the profitability of its domestic sales (by AMNS Calvert sufficiently to offset the negative effect on export sales). It is however unclear how long any such positive impact would last and what impact further tariffs on a widening list of imported products and retaliatory protectionist measures by other countries may have on global trade and ultimately economic growth, steel demand, steel and iron ore prices, or input costs (including energy and raw materials). In addition, the new U.S. administration and the U.S. Congress may make substantial changes in legislation, regulation and government policy directly affecting ArcelorMittal's business or indirectly affecting the Company because of impacts on its customers and suppliers; the current U.S. administration may seek to renegotiate free trade agreements or withdraw from the WTO, destabilizing global trade.

In addition, certain operations of ArcelorMittal may be a respondent to anti-dumping and countervailing duty cases and its exported products have been and in the future may be subject to anti-dumping and countervailing duties or other trade restrictions.

Russia's invasion of Ukraine, international reaction to it (in particular in the form of sanctions) and any regional or global escalation of the conflict, could adversely affect the Company's business, results of operations and financial condition.

The Company has significant operations in Ukraine, consisting of a steel plant and (captive) mines. See "Properties and capital expenditures—Property, plant and equipment— Others". After operating at various levels of capacity in 2022/2023 affected by various difficulties, ArcelorMittal Kryvyi Rih ("AMKR") is currently operating its open pit mines and steel facilities at 75% and 23%, respectively. The Company cannot predict the duration of the idling or of lower production as it will depend on the remaining course of the conflict and the establishment of safe and stable operating and logistical conditions thereafter, as well as potential repairs of any damages sustained. The Russian army has also blocked ports in Odessa, complicating and increasing the cost of exports (including steel and iron ore) from Ukraine. The ongoing conflict, its impact on demand, logistics (with respect to both supply and delivery) and costs and any resulting further reduced production, sales and income at its Ukrainian operations have caused the Company to record impairment charges (and may be required to record additional charges in

the future). For further information on these risks, see notes 1.3 and 5.3 to the consolidated financial statements.

The imposition of extensive sanctions on Russia by the EU, the U.S., the UK and other countries could affect the Company's sourcing of raw materials from sanctioned countries. Any business conducted in Russia and with Russian counterparties also carries the risk of non-compliance with economic sanctions (and the attendant financial and reputational adverse consequences), despite best efforts to comply. In addition, sanctions may remain in place beyond the duration of any military conflict and have a long-lasting impact on the region and could adversely impact the Company's results of operations and financial condition. More generally the conflict could have a further material adverse effect on the overall macroeconomic environment (see "Volatility in the supply and prices of raw materials, energy and transportation, and volatility in steel prices or mismatches between steel prices and raw material prices could adversely affect ArcelorMittal's results of operations"). The conflict could escalate militarily both regionally and globally; any substantial escalation would have a material adverse effect on macroeconomic conditions.

Competition from other materials and alternative steelbased technologies could reduce market prices and demand for steel products and thereby reduce ArcelorMittal's cash flows and profitability.

In many of its applications, steel competes with other materials that may be used as substitutes, such as aluminum, concrete, composites, glass, plastic and wood. In particular, as a result of increasingly stringent regulatory requirements, as well as developments in alternative materials, designers, engineers and industrial manufacturers, especially those in the automotive industry, have increased their use of lighter weight and alternative materials, such as aluminum and plastics.

A loss of market share to substitute materials, increased government regulatory initiatives favoring the use of alternative materials, as well as the development of additional new substitutes for steel products could significantly reduce market prices and demand for steel products and thereby reduce ArcelorMittal's cash flows and profitability.

New technologies such as carbon free steelmaking could also result in a loss of market share if competitors develop and deploy this kind of technology before, or more effectively than ArcelorMittal. In addition, to the extent regulatory requirements and/or customer demand for low carbon or carbon neutral steel increase, competition with respect to low CO2 steel technologies may become more significant, leading to substantial input cost increases.

II. Risks related to sustainability

The Group's announced carbon emissions intensity reduction targets were based on assumptions with respect to the costs, government and societal support for the reduction of carbon emissions in particular regions and the advancement of technology and infrastructure

related to the reduction of carbon emissions over time. Future developments may affect such assumptions, and this may render the achievement of ArcelorMittal's targets more difficult, or even impossible, to achieve for cost or other reasons.

The Company's decarbonization strategy includes the objective of carbon neutrality by 2050; the Company's medium-term objective and associated decarbonization capital expenditures are currently under review. ArcelorMittal's ability to achieve this objective depends on numerous factors and assumptions, including the costs of green hydrogen (meaning hydrogen produced exclusively from renewable sources) and its evolution over time, the construction of DRI and EAF facilities, the development of CCUS infrastructure and the timing of the introduction of GHG reduction requirements and supportive policies in applicable jurisdictions. In November 2024, the Company announced that it was unable to take final investment decisions on projects to replace blast furnaces with lower-carbon technology in Europe due to current conditions in European policy, energy and market environments, given green hydrogen's very slow evolution towards becoming a viable fuel source and natural gas-based DRI production in Europe not yet being a competitive interim solution. The development of low emissions technologies depends on more stringent global GHG reduction requirements and/or the introduction of carbon prices in each jurisdiction, alongside the introduction of effective policies to secure a level playing field. However, since Europe is currently the only major market to have implemented a cost on carbon, the Company has indicated that it needs further support from host countries, first and foremost from the European Union and its Member States, through more supportive policies designed to avoid "carbon leakage" and provide compensation for the significantly higher costs, while at the same time maintaining a fair and competitive landscape (particularly given that the CBAM adopted by the EU does not appear sufficient to ensure the level-playing field necessary to maintain the competitiveness of the steel industry in Europe).

In addition, ArcelorMittal's targets have been based on the assumption that public funding covers 50% of the total cost of decarbonization (capital expenditures and higher operating expenses, which are expected to be significant) so that the Company and industry are not rendered uncompetitive during this transition period. The Company believes this assumption is reasonable (and funding from certain governments has been approved), but such funding is subject to changes in government and policy, among other factors, and may not be achieved. See "Business overview—Sustainable development —Climate change and decarbonization". The new Trump administration in the United States appears unlikely to provide the support necessary for decarbonization, which may also influence adoption of such policies and support worldwide. A lack of governmental and societal support could make the Company's targets more costly, more difficult or even impossible to achieve. If the Company is unable to make the necessary investments to decarbonize and reach its

decarbonization targets due to the design of governmental policy in Europe or other jurisdictions where it operates (see "—Changes in assumptions underlying the carrying value of certain assets, including as a result of adverse market conditions, could result in the impairment of such assets, including intangible assets such as goodwill"), it may negatively affect its competitiveness, profitability, cash flows, financing costs, results of operations and financial condition, as well as harm its reputation.

Laws and regulations restricting emissions of greenhouse gases could force ArcelorMittal to incur increased capital and operating costs and could have a material adverse effect on ArcelorMittal's results of operations, financial condition and reputation.

The integrated steel process involves significant carbonfootprint. Compliance with new and more stringent environmental obligations relating to GHG emissions, including as part of the EU's "Fit for 55" package, may require additional capital expenditures or modifications in operating practices, as well as additional reporting obligations. See "Business Overview – Government Regulations— Environmental laws and regulations—Climate Change".

The new laws are all interconnected, and they combine: tightening and extending the existing emission trading system ("EU-ETS"); increased use of renewable energy; greater energy efficiency; a faster roll-out of low emission transport modes and the infrastructure and fuels to support them; an alignment of taxation policies with the European Green Deal objectives; a carbon border adjustment mechanism ("CBAM") to prevent carbon leakage; and tools to preserve and grow natural carbon sinks. Of particular relevance are the amending EU-ETS directive and the CBAM regulation, which entered into force in mid-2023, and will mainly impact the carbon emissions allowances from the second trading period of Phase IV of the EU-ETS (i.e., 2026-2030) onwards.

The implementation of Phase IV rules (applicable during the 2021-2030 period) has already resulted in increased EU allowances prices, which the Company expects will continue to increase, despite recent volatility. Moreover, as from 2026 free allocation of CO2 emissions allowances will be progressively phased out (and completely phased out as from 2034). This will contribute to a very significant shortage in free allocation in the later years of the second trading period of Phase IV (given the amount of CO2 emission allowances is currently insufficient to satisfy technically achievable operating conditions) and lead to significant increases in prices for emissions allowances. The Company's operations will be subject to the additional costs from these purchases, many of which may be significant and higher than currently expected and may or may not be effectively hedged in the future. In addition, the effectiveness of the CBAM remains untested and the provisions to address circumvention risks, including resource shuffling and cost absorption, may be insufficient, and no solution for exports has yet to be considered.

Similar regulations have been implemented to date in several jurisdictions, and additional measures may well be enacted in the future in other jurisdictions. Whether in the form of a national or international cap-and-trade emissions permit system, a carbon tax or acquisition of emission rights at market prices, emissions controls, reporting requirements, or other regulatory initiatives, such environmental regulations could have a negative effect on ArcelorMittal's production levels, income and cash flows. These regulations could also negatively affect the Company's suppliers and customers, which could translate into higher costs and lower sales.

Furthermore, many developing nations have not yet instituted significant GHG regulations, and the Paris Agreement specifically recognizes that GHG emissions will peak later in developing countries. As the Intended Nationally Determined Contributions ("INDC") for developing nations under the Paris Agreement may be less stringent than for developed nations in light of different national circumstances, ArcelorMittal may be at a competitive disadvantage relative to steelmakers having more or all of their production in developing countries. Depending on the extent of the difference between the requirements in developed regions (such as Europe) and developing regions (such as China or the CIS), this competitive disadvantage could be severe and has resulted, and in the future may result, in production cuts due to relatively higher carbon costs rendering production structurally unprofitable. See "Properties and capital expenditures— Property, plant and equipment" for further information regarding production levels by segment.

In addition, as regulators and investors increasingly focus on climate change issues, the Company is exposed to the risk of frameworks and regulations being adopted that are ill-adapted to steel industry dynamics. For example, the most established framework for carbon pricing and emissions trading schemes is currently the EU-ETS discussed above. As indicated above, while a CBAM has been adopted to limit competitive distortions from the ETS, it does not appear sufficient to enable the steel industry in Europe to remain competitive. Furthermore, the European Climate Law requires the Commission to present a legislative proposal of a Union 2040 target within six months of the first global stocktake, which concluded at COP28 in Dubai in December 2023. In February 2024, the Commission presented a communication recommending a 90% reduction in net emissions by 2040 compared to 1990, in line with the advice of the Scientific Advisory Board. The legislative proposal to table the 2040 climate target is the responsibility of the new Commission. It is expected that such a target would trigger a further review of the EU-ETS cap, likely leading to a tightened market that might drive higher prices for allowances.

For further information on environmental laws and regulations and how they affect the Company's operations, see "Business overview—Government regulations—Environmental laws and regulations" and note 9.1 to the consolidated financial statements.

ArcelorMittal is subject to strict environmental, health and safety laws and regulations that could give rise to a significant increase in costs and liabilities.

ArcelorMittal is subject to a broad range of environmental, health and safety laws and regulations in each of the jurisdictions in which it operates. These laws and regulations impose increasingly stringent standards regarding general health and safety, air emissions, discharges of wastewater, the use, handling and transportation of hazardous, toxic or dangerous materials, waste disposal practices and the remediation of environmental contamination, and health and safety matters, and permit requirements/limits among other things. The costs of complying with, and the imposition of liabilities pursuant to, these laws and regulations can be significant, and compliance with new and more stringent obligations may require additional capital expenditures or modifications in operating practices. Failure to comply can result in civil and or criminal penalties being imposed, the suspension of permits, requirements to curtail or suspend operations and lawsuits by third parties.

Despite ArcelorMittal's efforts to comply with environmental, health and safety laws and regulations, and monitor and reduce accidents at its facilities, health, safety and environmental incidents or accidents, including those involving serious injury or death, have occurred and may in the future occur. Such accidents could include (and in certain instances have included) explosions or gas leaks, fires or collapses in underground mining operations, crushing incidents, vehicular accidents, falls while working at heights, and other accidents involving mobile equipment, or exposure to radioactive or other potentially hazardous, toxic or dangerous materials, which have had, and could in the future have, significant adverse consequences for the Company's workers and facilities, as well as the environment. For example, the Company's previous operations in Kazakhstan suffered several fatal accidents.

Certain of these incidents may result in costs and liabilities and negatively impact the Company's reputation or the operations of the affected facilities. Such accidents could lead to production stoppages, loss of personnel, loss of key assets, or put at risk the Company's employees (and those of subcontractors and suppliers) or persons living near affected sites. In addition, any gap between community and worker expectations and ArcelorMittal's environmental, health and safety perceived performance, as a result of any accidents, safety incidents or even the perception of potential safety or environmental issues, may negatively impact community relations, labor relations, customer relations and the Company's reputation and result in disruptions to the Company's operations. ArcelorMittal's operations may also be located in areas where individuals or communities could regard its activities as having a detrimental effect on their natural environment and conditions of life, and actions taken by such individuals or communities in response to such concerns could compromise ArcelorMittal's profitability or, in

extreme cases, the viability of an operation or the development of new activities in the relevant region or country.

ArcelorMittal also incurs costs and liabilities associated with the assessment and remediation of contaminated sites, and in its mining activities, those resulting from tailings and sludge disposal, effluent management, and rehabilitation of land disturbed during mining processes. In addition to the impact on current facilities and operations, environmental remediation obligations can give rise to substantial liabilities in respect of divested assets and past activities. This may also be the case for acquisitions when liabilities for past acts or omissions are not adequately reflected in the terms and price of the acquisition. ArcelorMittal could become subject to further remediation obligations in the future, as additional contamination is discovered or clean-up standards become more stringent.

In addition, with respect to sustainability reporting, if based on information disclosed in accordance with new requirements (such as the Corporate Sustainability Reporting Directive, which specifies extensive and detailed sustainability information to be provided based on the reporting standard published in July 2023, or any new SEC rules) or otherwise, financial institutions or other stakeholders (including the public) begin to view investments in steel and mining as undesirable, it may become more difficult and/or more expensive for the Company to obtain financing. While the Company has taken significant steps and continues to adapt its operations in light of climate change and the need for sustainability, such steps may not be in line with future frameworks or regulations or market views of investment suitability. Moreover, the Company may in the future face increasing shareholder activism and/or litigation in relation to sustainability matters.

III. Risks related to ArcelorMittal's operations

ArcelorMittal could experience labor disputes that could have an adverse effect on its operations and financial results.

A majority of ArcelorMittal's employees and contractors are represented by labor unions and covered by collective bargaining or similar agreements, which are subject to periodic renegotiation. Strikes and work stoppages have occurred, and are likely to occur in the future, at various ArcelorMittal facilities prior to or during negotiations preceding new collective bargaining agreements, during wage and benefits negotiations or during other periods for other reasons, in particular in connection with any announced intentions to adapt its footprint. Strikes or work stoppages, particularly when prolonged, could disrupt ArcelorMittal's operations and relationships with its customers, as well as limit its ability to rationalize operations and reduce labor costs in certain

markets, resulting in an adverse effect on its operations and financial results.

Disruptions to ArcelorMittal's manufacturing processes and mining operations caused for example by equipment failures, natural disasters, accidents, explosions, epidemics or pandemics, geopolitical conflicts or extreme weather events could adversely affect its operations, customer service levels and financial results and liabilities.

Steel manufacturing processes are dependent on critical steelmaking equipment, such as furnaces, continuous casters, rolling mills and electrical equipment (such as transformers), and such equipment may incur downtime as a result of unanticipated failures or other events, such as fires, explosions, furnace breakdowns or as a result of natural disasters, accidents, epidemics or pandemics or severe weather conditions. ArcelorMittal's manufacturing plants and mines have experienced, and may in the future experience, plant shutdowns or periods of reduced production as a result of such events.

ArcelorMittal's mining operations, in particular, are subject to the hazards and risks usually associated with the exploration, development and production of natural resources through either open-pit or underground mining operations, any of which could result in production shortfalls or damage to persons or property, delay production, increase production costs and result in death or injury to persons, damage to property and liability for ArcelorMittal, some or all of which may not be covered by insurance, as well as substantially harm ArcelorMittal's reputation, both as a Company focused on ensuring the health and safety of its employees and more generally. Certain of these incidents have resulted or may result in fatalities, production stoppages, governmental investigations or proceedings and/or in costs and liabilities and negatively impact the Company's reputation or the operations of the affected facilities. Such hazardous incidents could also lead to loss of key personnel, loss of key assets, or health and safety risks for ArcelorMittal's employees (and those of subcontractors and suppliers) or persons living near affected sites. See also "—ArcelorMittal is subject to strict environmental, health and safety laws and regulations that could give rise to a significant increase in costs and liabilities". Conflicts may also cause interruptions to operations; see "— Russia's invasion of Ukraine, international reaction to it (in particular in the form of sanctions) and any regional or global escalation of the conflict, could adversely affect the Company's business, results of operations and financial condition".

In addition, natural disasters and severe weather conditions have led, and could in the future lead, to significant damage at ArcelorMittal's production facilities and general infrastructure or cause shutdowns, including due to earthquakes, tsunamis, tornados, hurricanes and bush fires. More generally, changing weather patterns and climatic conditions in recent years,

possibly due to climate change, have added to the unpredictability and frequency of natural disasters.

Severe weather conditions can also affect ArcelorMittal's operations in particular due to the long supply chain for certain of its operations and the location of certain operations in areas subject to harsh winter conditions (i.e., Canada) or areas that are susceptible to droughts (i.e., South Africa, Mexico and Brazil). Water in particular is crucial to the steelmaking process, and the risk that the authorities may restrict license to withdraw water as a result of chronic drought could increase operating costs and reduce production capacity. Flooding has also affected ArcelorMittal's operations, impacting shipment volumes due to handling and logistic constraints. Damage to ArcelorMittal production facilities due to natural disasters and severe weather conditions could, to the extent that lost production cannot be compensated for by unaffected facilities, adversely affect its business, results of operations or financial condition. More generally, these severe weather conditions could increase in frequency and severity due to climate change.

ArcelorMittal's reserve and resource estimates may materially differ from mineral quantities that it may be able to actually recover; ArcelorMittal's estimates of mine life may prove inaccurate; and changes in iron ore prices, operating and capital costs and other assumptions used to calculate these estimates may render certain reserves and resources uneconomical to mine.

There is a degree of uncertainty attributable to the estimation of mineral reserves and resources. Until mineral reserves and resources are actually mined and processed, the quantity of metal and grades must be considered as estimates only and no assurance can be given that the indicated levels of metals will be produced.

The estimation of mineral reserves and resources is a subjective process that is partially dependent upon the judgment of the qualified persons preparing such estimates. The process relies on the quantity and quality of available data and is based on knowledge, mining experience, statistical analysis of drilling and sampling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available.

ArcelorMittal periodically updates its mineral reserve and resources estimates based on the conclusions of the relevant qualified persons with respect to new data generated from exploratory and infill drilling campaigns, results from technical studies and the experience acquired during the operation of the mine and metallurgical processing, as well as changes to the assumptions used to calculate these estimates. Additional data generated may not be consistent with the data on which previous mineral resources and mineral reserves were based. Therefore, estimates may change from period to period or may need to be revised, and there can be no assurance that the mineral resources or mineral reserves in this report will be recovered at the grade, quality or quantities presented.

As a result, there can be uncertainty in the assumptions used that may materially impact and result in significant changes to the Company's current estimates. The assumptions that can fluctuate may include, but are not limited to: market prices including long-term forecasts; operating and capital costs; changes to estimation input parameters and techniques; and changes to cut-off grades, mining, and metallurgical recovery rates and, with respect to mineral resources, further engineering, legal and economic feasibility that would allow for the conversion to mineral reserves. These changes may also render some or all of ArcelorMittal's current proven and probable mineral reserves and measured and indicated mineral resources uneconomic to exploit and may ultimately result in a reduction of mineral reserves and resources. In addition, no assurance can be given that mineral resources (in particular inferred mineral resources, which are subject to a greater amount of uncertainty as to their existence and their economic and legal feasibility) will be upgraded to a higher category or that any of the mineral resources not already classified as mineral reserves will be reclassified as mineral reserves.

If a project proves not to be economically feasible by the time ArcelorMittal is able to exploit it, ArcelorMittal may incur substantial losses and be obliged to recognize impairments. In addition, potential changes or complications involving metallurgical and other technological processes that arise during the life of a project may result in delays and cost overruns that may render the project not economically feasible. In addition, ArcelorMittal faces rising extraction costs over time as reserves deplete.

ArcelorMittal's reputation and business could be materially harmed as a result of data breaches, data theft, unauthorized access or suspected or successful hacking. ArcelorMittal's operations depend on the secure and reliable performance of its information technology systems. ArcelorMittal, has experienced, and continues to experience, increasing intrusion attempts on its computer networks through sophisticated and targeted phishing, ransomware and virus attacks, some of which have resulted, and may in the future result, in breaches of its information technology security. See "—Cybersecurity".

Adverse consequences of technological advances like Industry 4.0, Cloud Computing, Internet of Things, GenAi and Blockchain may continue to increase threats or cause damage to ArcelorMittal, for example by impacting shop-floor systems supporting production and maintenance and thereby forcing plant operations to revert to manual mode with loss of production, resulting in new risks to ArcelorMittal's operations and systems. Because the techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently and often are not recognized until launched against a target, the Company may be unable to anticipate these techniques or to implement in a timely manner effective and efficient countermeasures. Although ArcelorMittal performs annual cyber maturity assessments in

many of its business units, which are supplemented by indepth cyber audits and penetration testing exercises performed by ArcelorMittal Global Assurance, the risk of significant data breaches, data theft, unauthorized access or successful hacking cannot be eliminated. There may also be an increased risk of cybersecurity breaches due to ongoing geopolitical tensions involving Russia or China. See also "— Cybersecurity".

If unauthorized parties attempt or manage to bring down the Company's website or force access into its information technology systems, they may be able to misappropriate personal and confidential information, cause interruptions in the Company's operations, damage its computers or process control systems or otherwise damage its reputation and business. Any compromise of the security of the Company's information technology systems or those of its suppliers or service providers could impact the Company's ability to maintain operations, disrupt the provision of services, result in a loss of confidence in the Company's security measures, subject it to litigation, civil or criminal penalties, regulatory actions (e.g., under the EU's General Data Protection Regulation) or adverse publicity, any of which could adversely affect its financial condition and results of operations.IV. Risks related to ArcelorMittal's acquisitions and investments

ArcelorMittal has grown through acquisitions and may continue to do so. Failure to manage external growth and difficulties completing planned acquisitions or integrating acquired companies could harm ArcelorMittal's future results of operations, financial condition and prospects.

The Company has made several large acquisitions in recent years. To the extent ArcelorMittal continues to pursue significant acquisitions, the associated financing may (depending on the structure) result in increased debt, leverage and gearing. Acquisitions also entail increased operating costs, as well as greater allocation of management resources away from daily operations. Managing acquisitions requires the continued development of ArcelorMittal's financial and management information control systems, the integration of acquired assets with existing operations, the adoption of manufacturing best practices, handling any labor disruptions that may arise, attracting and retaining qualified management and personnel as well as the continued training and supervision of such personnel, and the ability to manage the risks and liabilities associated with the acquired businesses. Acquisitions also have resulted, and may in the future result, in subsequent disputes or financial liabilities, including in respect of put options granted to selling shareholders over a retained minority stake. See note 9.3 to the consolidated financial statements for further information. In addition, acquisitions may entail future capital expenditures, either as a condition or in order to realize synergies, operational efficiencies or strategic benefits. Such capital expenditure may not provide the anticipated return on investment. More generally, failure to manage acquisitions could have a material adverse effect on ArcelorMittal's business, financial condition,

results of operations or prospects.ArcelorMittal is currently and in the future may be subject to legal proceedings or other proceedings, including in relation to its interest in ADI, the resolution of which could negatively affect the Company's profitability and cash flows in a particular period.

ArcelorMittal's profitability or cash flows in a particular period could be affected by adverse rulings in current and future legal proceedings against the Company. See note 9.3 to the consolidated financial statements.

In April 2021, ArcelorMittal and Invitalia, an Italian state-owned company, formed a public-private partnership, ADIH, to operate and subsequently acquire the Ilva business (which had to that point been managed by the Company and Italiangovernment appointed commissioners), providing Invitalia with joint control rights. In February 2024, the Italian government placed ADIH's main operating subsidiary ADI in EA (followed by a Milan court determination of ADI's insolvency), thereby passing control of the company to government-appointed commissioners and stripping ArcelorMittal of its rights as an indirect shareholder of ADI. ArcelorMittal was subsequently stripped of its rights as a direct shareholder in ADIH after being placed in EA and a Milan court determination of its insolvency. The Company's appeal against the Milan court decision is currently pending. ArcelorMittal has also appealed the Italian government EA decrees and the decrees authorizing ADI's commissioners to enter into a new interim lease agreement with Ilva's commissioners (to which ADIH is not a party) and authorizing a new sale process for Ilva's business. Hearings before the court have not yet taken place. The subsequent placement of ADI and ADIH in EA, a complex procedure, could well lead to further disputes. In this respect, in July 2024 the commissioners of ADI and ADIH filed with the court of Milan a request for an urgent technical assessment of the Ilva facilities stated to be in view of a potential claim for damages against AMIH and certain former directors of ADI; in December 2024 the Milan court rejected the request and its decision has since become final (without prejudice to a potential subsequent claim for damages).

ArcelorMittal's strategic growth, maintenance and decarbonization projects are subject to financing, execution and completion risks.

The Company has announced a number of strategic growth and decarbonization projects, which are capital intensive, and also regularly invests in significant maintenance capital expenditures. See "Properties and capital expenditures— Property, plant and equipment—Investments in joint ventures" and "Properties and capital expenditures—Capital expenditures". The cost or time to complete any of these projects may prove to be greater than originally anticipated. Timely completion in accordance with budgeted amounts and successful operation may be affected by factors beyond the control of ArcelorMittal. These factors include receiving financing on reasonable terms, obtaining or renewing required regulatory approvals and licenses, securing and maintaining

adequate property rights to land and mineral resources, local opposition to land acquisition or project development, managing relationships with or obtaining consents from other shareholders, revision of economic viability projections, demand for the Company's products, local environmental or health-related conditions, and general economic conditions. Any of these factors may cause the Company to delay, modify or forego some or all aspects of its development projects. For investment projects that the Company expects to fund primarily through internal sources, these sources may prove insufficient depending on the amount of internally generated cash flows and other uses of cash, and the Company may need to choose between incurring external financing or foregoing the investment. The Company cannot guarantee that it will be able to execute its greenfield, brownfield or other investment projects, and to the extent that they proceed, that it will be able to complete them on schedule, within budget, or achieve the volumes, revenues or anticipated return on its investment. Conversely, should the Company decide to postpone or cancel development projects, it could incur various negative consequences such as litigation or impairment charges, as well as loss of anticipated strategic benefits. ArcelorMittal faces risks associated with its investments in joint ventures and associates. ArcelorMittal has investments in numerous joint ventures and associates for a total carrying amount of \$11.4 billion at December 31, 2024. See "Properties and capital expenditures

—Property, plant and equipment—Investments in joint ventures" and note 2.4 to the consolidated financial statements. In particular, it has structured significant growth transactions in recent years, including Calvert, AMNS India and the joint venture with Casa dos Ventos. Joint ventures and associates subject ArcelorMittal to several types of risks.

First, risks that are endemic to joint ventures and associates generally due to their nature as entities over which control is shared or where ArcelorMittal only exercises significant influence. These include the risk of dead-lock and/or coordination issues affecting the implementation of strategy. To the extent joint ventures and associates are controlled and managed by partners, they may not fully comply with ArcelorMittal's standards, controls and procedures, including ArcelorMittal's health, safety, environment and community standards; this could lead to higher costs, reduced production or environmental, health and safety incidents or accidents, which could adversely affect ArcelorMittal's results and reputation.

Second, joint ventures may be the source of substantial expenditures and financial exposure. Although ArcelorMittal's joint ventures are responsible for their own debt repayment and the Company does not consolidate their indebtedness but has guaranteed certain debt or contractual obligations of its joint ventures (see note 9.4 to ArcelorMittal's consolidated financial statements). Particularly if the joint venture experiences financial difficulties, ArcelorMittal may make substantial cash contributions to extend loans or address calls on existing guarantees and is exposed to a risk of loss of its investment.

Financial risks may be particularly high for joint ventures that are strategic and that are expanding and developing, such as AMNS India and Calvert (see "Property and Capital expenditures—Investments in joint ventures" and "Property and Capital expenditures—Capital expenditures"). AMNS India, in particular, has large-scale and ambitious projects to expand its operations and further improve operational profitability, which may either not come to fruition or require greater than anticipated investments or expenditures. AMNS India has also made significant acquisitions in recent years that it has financed with its own cash and drawings under existing financings (including ones guaranteed by its shareholders). The Company currently expects that any future acquisitions would likely be similarly financed. Moreover, the joint venture has announced \$7.7 billion in projected capital expenditure requirements that it expects to finance similarly (subject to potential cost overruns). The risks in this respect are compounded to an extent by the fact that AMNS India is owned and operated by a joint venture with attendant risks around strategic alignment, potential discord and deadlock.

ArcelorMittal's investments in joint ventures and associates (whether current investments or future ones) have resulted, and may in the future result, in impairments (the Company recognized a \$1.4 billion impairment charge with respect to its investment in ADI in 2023).

V. Risks related to ArcelorMittal's financial position and organizational structure

Changes in assumptions underlying the carrying value of certain assets, including as a result of adverse market conditions, could result in the impairment of such assets, including intangible assets such as goodwill.

At each reporting date, in accordance with the Company's accounting policy described in note 5.3 to the consolidated financial statements, ArcelorMittal reviews the carrying amounts of its tangible and intangible assets (goodwill is reviewed annually or whenever changes in circumstances indicate that the carrying amount may not be recoverable) to determine whether there is any indication that the carrying amount of those assets may not be recoverable through continuing use. If any such indication exists, the recoverable amount of the asset (or cash-generating unit) is reviewed in order to determine the amount of the impairment, if any.

If certain of management's estimates change during a given period, such as the discount rate, capital expenditures, expected changes to average selling prices, growth rates, shipments and direct costs, the estimate of the recoverable amount of goodwill or the asset could fall significantly and result in impairment. The Company has recorded significant impairment charges over the years, including recently. While impairment does not affect reported cash flows, decreases of the estimated recoverable amount and the related non-cash charge in the consolidated statements of operations have had and could have a material adverse effect on ArcelorMittal's results of operations. Substantial amounts of goodwill and tangible and intangible assets remain recorded on the Company's consolidated statement of financial position. As of December 31, 2024, the Company's balance sheet included \$3.6 billion of goodwill.

More generally, no assurance can be given as to the absence of significant further impairment losses in future periods, particularly if market conditions deteriorate. In particular, changes in key assumptions used in the Group's impairment tests, due to market conditions, regulations (including environmental and carbon emission regulations) or other reasons (for example, assumptions regarding decarbonization costs) may result in additional impairment losses being recognized in the future. For further information on these risks and uncertainties in assumptions, see notes 1.3 to the consolidated financial statements.

ArcelorMittal's indebtedness could have an adverse impact on its results of operations and financial position, and the market's perception of ArcelorMittal's leverage or of certain financial transactions may affect the price of its securities.

As of December 31, 2024, ArcelorMittal had total debt outstanding of \$11.6 billion, \$6.5 billion of cash and cash equivalents and restricted cash, and \$5.5 billion available to be drawn under existing credit facilities. The Company also relies on its true sale of receivables programs (\$4.4 billion of trade receivables sold at December 31, 2024), as a way to manage its working capital cycle. A substantial increase in indebtedness could contribute to the Company's vulnerability to adverse economic and competitive pressures in its industry, limit flexibility in planning for, or reacting to, changes in its business and industry; limit its ability to borrow additional funds on terms that are acceptable to the Company or at all. More generally, a deterioration of market conditions may impact ArcelorMittal's ability to refinance its indebtedness on acceptable conditions or at all. In addition, credit rating agencies could downgrade ArcelorMittal's ratings either due to factors specific to ArcelorMittal, a prolonged cyclical downturn in the steel industry and mining industries, macroeconomic trends (such as global or regional recessions or economic shocks) or trends in credit and capital markets more generally. The margin under ArcelorMittal's principal credit facilities and certain of its outstanding bonds is subject to adjustment in the event of a change in its long-term credit ratings, and downgrades that occurred in the past resulted in increased interest expense.

Restrictive covenants in ArcelorMittal's debt instruments (current or future) may limit ArcelorMittal's operating and financial flexibility. Failure to comply with any covenant would enable the lenders to accelerate ArcelorMittal's repayment obligations. In addition, the mere market perception of a potential breach of any financial covenant, to the extent in effect, could have a negative impact on ArcelorMittal's ability to refinance its indebtedness on acceptable conditions.

In addition to the foregoing specific risks relating to ArcelorMittal's indebtedness, the prices of its securities may be affected by the markets' perception of its leverage or any potential financial transactions, such as equity offerings, which may be implemented to increase financial flexibility.

ArcelorMittal's ability to fully utilize its recognized deferred tax assets depends on its profitability and future cash flows.

At December 31, 2024, ArcelorMittal had \$8.9 billion recorded as deferred tax assets on its consolidated statement of financial position, representing a \$0.6 billion decrease as compared to December 31, 2023. The deferred tax assets can be utilized only if, and only to the extent that, ArcelorMittal's operating subsidiaries generate adequate levels of taxable income in future periods to offset the tax loss carry forwards and reverse the temporary differences prior to expiration. At December 31, 2024, the amount of future income required to recover ArcelorMittal's deferred tax assets of \$8.9 billion was at least \$39.3 billion at certain operating subsidiaries.

ArcelorMittal's ability to generate taxable income is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control. If ArcelorMittal generates lower taxable income than the amount it has assumed in determining its deferred tax assets, then the value of deferred tax assets will be reduced. In addition, assumptions regarding the future recoverability of deferred tax assets depend on management's estimates of future taxable income in accordance with the tax laws applicable to ArcelorMittal's subsidiaries in the countries in which they operate. If in the course of its assessments management determines that the carrying amount of any of its deferred tax assets may not be recoverable pursuant to such prevailing tax laws, the recoverable amount of such deferred tax assets may be impaired.

Underfunding of pension and other post-retirement benefit plans at some of ArcelorMittal's operating subsidiaries could require the Company to make substantial cash contributions to pension plans or to pay for employee healthcare, which may reduce the cash available for ArcelorMittal's business.

ArcelorMittal's principal operating subsidiaries in Brazil, Canada, Europe and South Africa provide defined benefit pension and other post-retirement benefit plans to their employees. Some of these plans are currently underfunded, see note 8.2 to the consolidated financial statements for the total value of plan assets and any deficit.

ArcelorMittal's funding obligations depend upon future asset performance, which is tied to equity and debt markets to a substantial extent, the level of interest rates used to discount future liabilities, actuarial assumptions and experience, benefit plan changes and government regulation. Because of the large number of variables that determine pension funding requirements, which are difficult to predict, as well as any legislative action, future cash funding requirements for

ArcelorMittal's pension plans and other post-employment benefit plans could be significantly higher than current estimates. Increases in the general life expectancy assumption have contributed to increases in the defined benefit obligation. In these circumstances, funding requirements could have a material adverse effect on ArcelorMittal's business, financial condition, results of operations or prospects.

ArcelorMittal's results of operations could be affected by fluctuations in foreign exchange rates, particularly the euro to U.S. dollar exchange rate, as well as by exchange controls imposed by governmental authorities in the countries where it operates.

ArcelorMittal operates and sells products globally and as a result, its business, financial condition, results of operations or prospects could be adversely affected by fluctuations in exchange rates. A substantial portion of ArcelorMittal's assets, liabilities, operating costs, sales and earnings are denominated in currencies other than the U.S. dollar (ArcelorMittal's reporting currency). Accordingly, its results of operations are subject to translation risk (i.e., the U.S. dollar value of revenue and profits generated in other currencies and its debt denominated in other currencies), including, as has been recently occurred, due to the reclassification of cumulative foreign exchange translation losses upon a disposal of a subsidiary, and transaction risk (i.e., a mismatch between the currency of costs and revenue).

Moreover, ArcelorMittal operates in several countries whose currencies are, or have in the past been, subject to limitations imposed by those countries' central banks, or which have experienced sudden and significant devaluations. In emerging countries where ArcelorMittal has operations and/or generates substantial revenue, such as Argentina, Brazil, India, South Africa, Venezuela and Ukraine, the risk of significant currency devaluation is high.

Currency devaluations, the imposition of new exchange controls or other similar restrictions on currency convertibility, or the tightening of existing controls in the countries in which ArcelorMittal operates could adversely affect its business, financial condition, results of operations or prospects. The Significant Shareholder could exercise significant influence over the outcome of shareholder votes.

At December 31, 2024, HSBC Trustee (C.I.) Limited, as trustee of a fully discretionary trust (referred to as the "Significant Shareholder"), beneficially owned (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended) ordinary shares amounting to 340,072,244 in the aggregate (when aggregated with ordinary shares of ArcelorMittal held directly by Mr. Lakshmi N. Mittal and Mrs. Usha Mittal), representing 44.25% of ArcelorMittal's then outstanding shares. As a result, the Significant Shareholder could exercise significant influence over the decisions adopted at the ArcelorMittal general meetings of shareholders, including matters involving mergers or other business combinations, the acquisition or disposition of assets,

issuances of equity and obtaining funding through debt. The Significant Shareholder could also exercise significant influence over a change of control of ArcelorMittal. Mr. Lakshmi N. Mittal and Mrs. Usha Mittal are discretionary beneficiaries of the trust. For further information on the Company's major shareholders, see "Shareholders and markets—Major shareholders".

VI. Legal and regulatory risks

The income tax liability of ArcelorMittal may substantially increase if the tax laws and regulations in countries in which it operates change or become subject to adverse interpretations or inconsistent enforcement.

Taxes payable by companies in many of the countries in which ArcelorMittal operates are substantial and include value-added tax, excise duties, profit taxes, payroll-related taxes, property taxes, mining taxes and other taxes. Tax laws and regulations in some of these countries may be subject to frequent change, varying interpretation and inconsistent enforcement. Ineffective tax collection systems and national or local government budget requirements may increase the likelihood of the imposition of arbitrary or onerous taxes and penalties, which could have a material adverse effect on ArcelorMittal's financial condition and results of operations. In addition to the usual tax burden imposed on taxpayers, these conditions create uncertainty as to the tax implications of various business decisions. This uncertainty could expose ArcelorMittal to significant fines and penalties and to enforcement measures despite its best efforts at compliance, and could result in a greater than expected tax burden. See note 10 to the consolidated financial statements.

It is possible that tax authorities in the countries in which ArcelorMittal operates will introduce additional revenue raising measures. The introduction of any such provisions or modification of tax rates, tax laws, treaties in an adverse manner may affect the overall tax efficiency of ArcelorMittal and may result in significant additional taxes becoming payable and adversely effect on the Company's financial condition, results of operations, cash flows, liquidity and ability to pay dividends.

ArcelorMittal is subject to economic policy, military, political, social and legal risks and uncertainties in the markets (including emerging ones) in which it operates or proposes to operate, and these uncertainties may have a material adverse effect on ArcelorMittal's business, financial condition, results of operations or prospects. ArcelorMittal operates globally including in a large number of emerging markets. Many of these countries have implemented measures aimed at improving the business environment and providing a stable platform for economic development. ArcelorMittal's business strategy has been developed partly on the assumption that this modernization, restructuring and upgrading of the business climate and physical infrastructure will continue, but this cannot be guaranteed. In particular, certain of these markets have experienced or are experiencing particularly difficult operating conditions. Many emerging markets are also at risk of economic crises (be it external debt, currency, domestic corporate, household or public debt crises) usually brought on by an economic or political shock which can exacerbate existing domestic structural imbalances. For example, crises in Argentina and Turkey have had negative impacts on the Company's core markets in Brazil and the EU, respectively. Any slowdown in the development of these economies could have a material adverse effect on ArcelorMittal's business, financial condition, results of operations or prospects, as could insufficient investment by government agencies or the private sector in physical infrastructure. For example, the failure of a country to develop reliable electricity and natural gas supplies and networks, and any resulting shortages or rationing, could lead to disruptions in ArcelorMittal's production.

Moreover, some of the countries in which ArcelorMittal operates have been undergoing substantial political transformations from centrally controlled command economies to market-oriented systems or from authoritarian regimes to democratically elected governments and vice-versa. Political, economic and legal reforms necessary to complete such transformation may not progress sufficiently. On occasion, ethnic, religious, historical and other divisions have given rise to tensions and, in certain cases, wide-scale civil disturbances and military conflict. The political systems in these countries are vulnerable to their populations' dissatisfaction with their government, reforms or the lack thereof, social and ethnic unrest and changes in governmental policies. The prospect of further unrest and resulting political or economic destabilization cannot be ruled out. Furthermore, certain of ArcelorMittal's operations are also located in areas where acute drug-related violence (including executions and kidnappings of non-gang civilians) occurs and the largest drug cartels operate, such as the states of Michoacán, Sinaloa and Sonora in Mexico.

Furthermore, ArcelorMittal's operations in certain countries may be affected by military conflicts, such as in Ukraine. Any of these developments could have a material adverse effect on ArcelorMittal's business, financial condition, results of operations or prospects and its ability to continue to do business in these countries.

Moreover, the legal systems in some of the countries in which ArcelorMittal operates remain less than fully developed, particularly with respect to the independence of the judiciary, property rights, the protection of foreign investment and bankruptcy proceedings, generally resulting in a lower level of legal certainty or security for foreign investment than in more developed countries. ArcelorMittal may encounter difficulties in enforcing court judgments or arbitral awards in some countries in which it operates because, among other reasons, those countries may not be parties to treaties that recognize the mutual enforcement of court judgments. Assets in certain countries where ArcelorMittal operates could also be at risk of expropriation or nationalization. In addition, the Venezuelan

government has implemented a number of selective nationalizations of companies operating in the country to date. Although ArcelorMittal believes that the long-term growth potential in emerging markets is strong, and intends them to be the focus of the majority of its near-term growth capital expenditures, legal obstacles could have a material adverse effect on the implementation of ArcelorMittal's growth plans and its operations in such countries.

ArcelorMittal is subject to an extensive, complex and evolving regulatory framework which may expose it and its subsidiaries, joint ventures and associates to investigations by governmental authorities, litigation and fines, in relation, among other things, to antitrust and compliance matters. The resolution of such matters could negatively affect the Company's strategy, operations, profitability and cash flows in a particular period or harm its reputation.

ArcelorMittal's business encompasses multiple jurisdictions and complex regulatory frameworks, including in relation to antitrust, and economic sanctions, anti-corruption and antimoney laundering matters. Laws and regulations in these areas are complex and constantly evolving and enforcement of them continues to increase. ArcelorMittal may as a result become subject to increasing limitations on its business activities and to the risk of fines or other sanctions for noncompliance. From time to time, the Company is subject to review by authorities that monitor market power in any of the markets in which it operates. To the extent that ArcelorMittal is deemed by relevant authorities to exhibit significant market power, it can be subject to various regulatory obligations and restrictions, such as disposing of assets or granting access to its operations to third parties or being prevented from completing acquisitions, which could thereby adversely affect its results of operations and profitability. As a result of its position in the steel industry and its historical growth through acquisitions, ArcelorMittal could be subject to governmental investigations and lawsuits by private parties based on antitrust laws. These could require significant expenditures and result in liabilities or governmental orders that could have a material adverse effect on ArcelorMittal's business, operating results, financial condition and prospects. An adverse ruling in such type of proceedings could subject ArcelorMittal to substantial administrative penalties and/or civil damages. No assurance can be given that the Company will not be identified as having significant market power in any relevant markets in the future and that it will not be subject to additional regulatory requirements.

ArcelorMittal's governance and compliance processes, which include the review of internal controls over financial reporting as well as a Code of Business Conduct and other rules and protocols for the conduct of business, may not prevent breaches of laws and regulations or internal policies relating to compliance matters at ArcelorMittal or its subsidiaries, as well as to instances of non-compliant behavior by its employees, contractors or other agents. Any material weakness in internal control over financial reporting (including as identified by the

Company as of December 31, 2023 see "Additional Information—Management's report on internal control over financial reporting") could reduce confidence in the Company's published information, impact access to capital markets or the trading price of its securities. The risk of non-compliance is also present at ArcelorMittal's joint ventures and associates where ArcelorMittal has a non-controlling stake and does not control governance practices or accounting and reporting procedures.

Furthermore, ArcelorMittal is subject to evolving laws, regulations, policies, and international accords relating to matters beyond its core operations, including environmental sustainability, climate change, human capital, and employment matters. Some of these have recently come under increasing scrutiny. For example, in January 2025, President Trump signed a number of Executive Orders focused on diversity, equity and inclusion ("DEI"), which indicate continued scrutiny of DEI initiatives and potential related investigations of certain private entities with respect to DEI initiatives, including publicly traded companies. If ArcelorMittal does not successfully manage expectations across varied stakeholder interests, it could erode stakeholder trust and impact its reputation. Such scrutiny could also expose ArcelorMittal to the risk of litigation, investigations and enforcement actions or challenges, including by U.S. federal or state authorities, or result in reputational harm.

Unfavorable outcomes in current and potential future litigation and investigations relating to antitrust and compliance matters could reduce ArcelorMittal's liquidity and negatively affect its profitability, cash flows, results of operations and financial condition, as well as harm its reputation.

U.S. investors may have difficulty enforcing civil liabilities against ArcelorMittal and its directors and senior management.

ArcelorMittal is incorporated under the laws of the Grand Duchy of Luxembourg with its principal executive offices and corporate headquarters in Luxembourg. The majority of ArcelorMittal's directors and senior management are residents of jurisdictions outside of the United States. The majority of ArcelorMittal's assets and the assets of these persons are located outside the United States. As a result, U.S. investors may find it difficult to effect service of process within the United States upon ArcelorMittal or these persons or to enforce outside the United States judgments obtained against ArcelorMittal or these persons in U.S. courts, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. Likewise, it may also be difficult for an investor to enforce in U.S. courts judgments obtained against ArcelorMittal or these persons in courts in jurisdictions outside the United States, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. It may also be difficult for a U.S. investor to bring an original action in a Luxembourg court predicated upon the civil liability provisions of the U.S. federal securities laws against

ArcelorMittal's directors and senior management and non-U.S. experts named in this annual report.

Risk management process

Management is responsible for internal control in the Company and has implemented on an ongoing basis a robust short, medium and long-term risk – including ESG-related risks – management and control system, which is designed to ensure its business is focused on achieving its objectives and that significant risks are identified and mitigated. The system is also designed to ensure compliance with relevant laws and regulations.

The Company's risk management and internal control system is designed to determine risks in relation to the achievement of business objectives and appropriate risk responses. The establishment and maintenance of a risk identification and management process is the responsibility of site/segment/ corporate function management. Risks are owned and monitored by management. Risk officers designated by management facilitate the conversations and help monitoring the action plans. Critical risks are escalated through existing reporting lines. Critical risk decisions are not dissociated from the other decisions. Risks are analyzed by building models and developing scenarios to understand potential financial impacts. Short-term risks (within a 12-month time frame) are identified through a bottom-up process by respective management teams. Risks are identified through a defined process by respective management teams. Business segments and corporate functions consolidate the identified risks and report the top ones as part of the periodic reporting to key internal stakeholders. The Company uses a risk management framework based on a blend of a COSO (the Committee of Sponsoring Organizations of the Treadway Commission) 2013, ISO 31000 and an in-house model. Sites assess risks, including ESG and climate related risks, by assigning them a probability of occurrence, potential financial impact and/or non-financial consequences. Global trends, and the risks and opportunities identified as arising from them, are used to inform the Company's strategic outlook and planning.

Based on management reviews, reviews of the design and implementation of the Company's risk management approach and business and functional risk committees, management provides an assessment each year, as required by law, of the effectiveness of the Company's risk management process.

It should be noted, however, that the above does not imply that these systems and procedures provide certainty as to the realization of operational and financial business objectives, nor can they prevent all misstatements, inaccuracies, errors, fraud and non-compliance with rules and regulations.

The Audit & Risk Committee assists the Board of Directors with the oversight of risks to which the ArcelorMittal group is exposed and in the monitoring and review of the riskmanagement framework and process.

The Global Assurance Department facilitates the risk management process and provides support enabling business as well as corporate functions to identify these risks and opportunities to the business based on social, environmental, regulatory, workforce, stakeholder, resource, technological and other trends, and specify mitigation actions. A consolidated report is shared on a half-yearly basis with the key stakeholders.

With respect to climate, the work is coordinated by ArcelorMittal's executive officer for corporate business optimization in consultation with segment CEOs; discussed on a regular basis by the Group Management Committee; and overseen by the Executive Office, which provides leadership and guidance. The Company's climate strategy financial risks are brought to the attention of the Group Management Committee and where financially significant at a group level, are addressed at the Corporate Finance and Tax Committee. Central to the Company's approach is its work to advocate for policy support strategy to ensure that ArcelorMittal can respond to rising carbon prices with viable investments in decarbonization technologies. At the same time, all of ArcelorMittal's business segments are required to prepare carbon emission reduction plans to reach net zero by 2050 as part of the annual planning cycle.

With respect to security, the Company has put in place means to ensure the security of its people, assets and intellectual property by supporting business units on security governance, security risk management, operational security, strategy and continuous improvement. It develops and promotes security policies, procedures, tools and processes to support security process owners with identifying and assessing security risks, related to people, assets and intellectual property. It also identifies gaps, and implements appropriate leading practice security controls to promote more secure and resilient business environments.

As regards risks relating to the security of information systems, ArcelorMittal has developed governance and security rules which describe the recommended organization, infrastructure and operating procedures. These provisions are applied across the Company under the responsibility of the business segments. The Group Chief Information Security Office defines cyber security policies available and applicable for all segments/units globally and develops general directives in cyber security reflecting mission, goals and values of ArcelorMittal. The cyber security policy focuses on protecting information systems against disclosure to unauthorized users (confidentiality), improper modification (integrity) and nonaccess when required (availability). In addition, cyber maturity assessments are performed annually in many business units and supplemented by in-depth cyber audits and penetration testing exercises performed by Global Assurance. For more detailed information regarding the Company's cybersecurity risk management and strategy, see "Cybersecurity" below.

Regarding risks relating to changes in the regulatory environment and business ethics, the Legal, Compliance & Company Secretary Department ("LCCSD") reporting to the Chief Financial Officer establishes the Company's legal policy. It provides effective advice to assist in identification and monitoring of legal, regulatory and governance risks. The LCCSD is supported by regional and segment general counsels located across the business, who are further supported by unit or country general counsels. The Compliance structure is headed by Group Compliance and the Data Protection Officer who report to the Group General Counsel. The Group Compliance and Data Protection Officer is supported by a Corporate Compliance team and a Groupwide compliance network.

Internal control procedures

ArcelorMittal's internal control framework is based on the COSO 2013. It includes the following five components: control environment, risk assessment, control activity, information and communication and monitoring activities.

ArcelorMittal's internal controls aim to provide reasonable assurance but not absolute assurance because of the inherent limitations around effectiveness and efficiency of business operations, reliability of financial information, compliance with laws and regulations and compliance with policies and procedures. The organization of ArcelorMittal's internal control is aligned with group organization following which corporate functions, business segments and operational entities are directly accountable for establishing and maintaining effective and adequate internal controls and procedures that conform to the regulatory framework. The principles of control fit into the framework of the rules of corporate governance. In particular, these rules task the Audit & Risk Committee with monitoring the effectiveness of the internal control and risk management systems and of the internal audit, particularly as regards the procedures for preparing and dealing with accounting, financial and non-financial reporting.

Control environment

ArcelorMittal's control environment is primarily based on its Code of Business Conduct and supported by a comprehensive framework of policies and procedures in areas such as human rights, anti-corruption and insider dealing. These documents reflect the principles and concepts of the UN Global Compact, the OECD Guidelines on Multinational Enterprises and UN Sustainable Development Goal 16: peace, justice and strong institutions. The Company's Code of Business Conduct defines what acting with integrity means in practice. It applies to all directors, officers and employees of ArcelorMittal worldwide. To maintain knowledge about the Code of Business Conduct and other aspects of compliance, employees take part in training programs based on a matrix system covering economic sanctions, prevention of corruption, insider dealing regulation, fraud awareness and prevention, anti-trust issues, human rights, data protection and the Code of Business Conduct every three years.

The Board of Directors, with the support of its Committees, ensures that internal control functions operate properly. The Audit & Risk Committee monitors the effectiveness of internal control and risk management systems implemented by the Board of Directors and management. As part of its role to foster open communication, the Audit & Risk Committee meets at least annually with management, the head of Global Assurance and the Company's independent accountants in separate executive sessions to discuss any matters that the Audit & Risk Committee or each of these persons believe should be discussed privately. Management's responsibility is to ensure that the organizational structure plans, executes, controls and periodically assesses the Company's activities. It regularly reviews the relevance of the organizational structures so as to be in a position to adapt them swiftly to changes in the activities and in the environment in which they are carried out. The business segments' and operational entities' management are responsible for the internal control and risk management system within their scope of responsibility.

ArcelorMittal has defined responsibilities that cover the three dimensions of internal control: operational management, which is responsible for implementing internal control, support functions such as Finance, Legal, Treasury or Human Resources, Health & Safety and Sustainability & Environment which prescribe the internal control systems, verify their implementation and effectiveness and assist operational employees, and Global Assurance who, through their audit reports, provide recommendations to improve the effectiveness of the systems.

Following a risk-based approach, business processes and/ or management systems may be the subject of an internal audit performed by the Global Assurance Department reporting to both the Audit & Risk Committee Chair and the Group Executive Chairman in accordance with the international framework of the internal audit and its Code of Ethics. The audit plan, which is risk based, is submitted annually to the Audit & Risk Committee. The Global Assurance department presents its results to the management of operational entities and business segments and reports to the Audit & Risk Committee, Executive Office and Group CFO.

The design and effectiveness of the key operational, financial and information technology controls related to internal control over financial reporting, are regularly examined and assessed in compliance with the Sarbanes-Oxley Act.

Cybersecurity

Risk management and strategy

The Group Chief Information Security Officer and Head of Cyber Strategy ("CISO") follows the Group risk management program as defined by the Global Assurance team in the management of risks relating to the security of information systems. For further information on the Global Assurance team, see "Corporate governance—Sustainability committee —Global Assurance". The Group CISO is an experienced information technology and operation technology executive. He is a leading international chief information officer with proven expertise in cyber security, digital transformation, IT

integration and business enablement. He joined ArcelorMittal in 2024 from a leading transportation / logistics company where he served as their IT senior vice president and international CIO from 2017. He holds an MBA in international management from the Thunderbird School of Global Management, Glendale, Arizona, USA, and a Bachelor of Engineering in electronics and communication from the National Institute of Technology, Trichy, India.

On a quarterly basis, the Group CISO provides a cybersecurity risk report to the Group Finance Risk Committee, headed by the Group CFO, based on risks identified at the segment level, which in turn reports to and assists the Board of Directors in fulfilling its oversight responsibilities with respect to legal and regulatory requirements, including cybersecurity. Risks identified in the report are considered potential risks that may affect all functions and departments across the Group. The office of the CISO has identified the following four key risk areas:

• 1. Large-scale cyber-attacks or malware causing economic damage and/or reputational harm to ArcelorMittal.
• 1. Dependency risks and increased vulnerability to outages of critical systems (applications or infrastructure) causing significant disruption to ArcelorMittal.
• 1. Adverse consequences of technological advances such as Artificial Intelligence ("AI"), cloud-based programs or systems, Internet of Things ("IoT") and Blockchain, which may cause harm to ArcelorMittal.
• 1. Wrongful exploitation of personal information causing regulatory liabilities (e.g., GDPR or similar laws) or of business data causing contractual or other legal liabilities (e.g., relating to IP, R&D or customers) that would have significant negative impacts on ArcelorMittal.

As part of the risk management process, the Group's local IT teams, segment CIOs and segment CISOs also identify local cyber risks and report to the Group Finance Risk Committee.

The office of the CISO defines policies and procedures related to cyber and information security as well as to permissible and secure uses of cloud, operational technology ("OT") and IoT within the Company. ArcelorMittal follows the National Institute of Standards and Technology Cybersecurity Framework ("NIST CSF"). The Group's cybersecurity policies focus on protecting information systems against disclosure to unauthorized users (confidentiality), improper modification (integrity) and non-access when required (availability). These polices are implemented across the Group and tracked and reported on a quarterly basis. Additionally, the Company has in place a global incident and crisis process with special procedures for ransomware and data privacy (e.g., to increase protection and address breaches). Most Group entities undergo periodic security penetration testing exercises led by the Group CIO/ CISO team or external third parties throughout

the year. Global Assurance as part of risk based approach also conducts penetration tests independently.

The Company engages a wide range of third parties as part of the implementation and operationalization of its cybersecurity policies, cyber defense strategies and general cyber risk management, including specialist assessors, security consultants, IT auditors, forensic analysts, malware analysts and other third-party specialists. All third-party security providers that handle Company data or otherwise have access to ArcelorMittal's network and systems are required to complete a rigorous risk assessment program in an online platform, which includes checks for data and cloud security, access, incident reporting and physical protection in accordance with the NIST CSF as well as applicable Company cybersecurity policies.

In addition, Cyber Maturity Assessments are performed annually by an external consultant across many entities and segments for both IT and OT. Assessments are evidencebased exercises focusing on many key cyber processes, such as Vulnerability and Incident Management, Patching and Change Management, Malware Protection, Network Monitoring, Business Continuity and Disaster Recovery, and Software Security. Additionally, Global Assurance, as part of its risk based approach, performs cyber audits and penetration tests (as part of the annual plan).

ArcelorMittal has been a long-standing customer of the BitSight rating service and has defined specific target levels and KPIs for cybersecurity in the BitSight platform. These risk measures are monitored daily and reported quarterly to the Data Protection Committee, led by the Group Data Protection Officer with representation from Group Compliance, Group HR and the Group CISO. BitSight also reports ArcelorMittal's risk profile to Glass-Lewis for purposes of investor reporting.

The office of the CISO has put in place an extensive online dashboard that tracks various metrics related to cybersecurity risks across various operating units. Such measures include:

• 1. BitSight External Cyber Ratings and Risk Factors
• 1. AntiMalware compliance levels
• 1. Active Directory security posture
• 1. Cloud Security cyber score and framework adoption
• 1. Ransomware Exploitable Vulnerability remediation status
• 1. Externally Facing Web Application Vulnerability levels
• 1. Cyber Awareness Education and Training
• 1. OS Level and Patching posture
• 1. Mobile security compliance
• 1. Security Baselines (IT and OT) quarterly assessments
• 1. Expired user account risk
• 1. Cyber attack simulation effectiveness

Cybersecurity Related Events in 2024

In 2024, ArcelorMittal did not experience any cyber-attacks, cybersecurity threats or other information security incidents that materially affected or were reasonably likely to materially affect the Company's business strategy, results of operations or financial condition. See "Risk factors and control— ArcelorMittal's reputation and business could be materially harmed as a result of data breaches, data theft, unauthorized access or successful hacking".

Governance

ArcelorMittal has implemented a distributed organizational model. At the Group level, the Group CISO defines the global cybersecurity strategy and roadmap.

The global cybersecurity strategy and roadmap is informed by the ArcelorMittal Security Incident Classification and Escalation Procedures as well as the ArcelorMittal Cyber Crisis Management Procedures (collectively, the "Cybersecurity Procedures"). The Cybersecurity Procedures define the core principles of security risk management and the procedures for security management, including the roles and responsibilities of key personnel, strategy and measures to cope with information security breaches and related communication procedures.

Every cybersecurity occurrence or threat that rises to a specific level defined in the Cybersecurity Procedures is reviewed in the various security councils set out below and communicated to the appropriate committees as defined in the Cybersecurity Procedures. Any such cyber incident is promptly reported by the Group CISO to (a) the Global Ransomware Crisis Committee and (b) the Group CFO and Disclosure Committee for decision-making regarding external communication to regulators or investors.

In fulfilling its oversight responsibilities, the Board oversees cyber risks and incidents via the Audit & Risk Committee and approves proposals or modifications to the Cybersecurity Procedures. The Audit & Risk Committee relies on information provided from Global Assurance, to which the Group CFO provides information about risks. The Group CFO provides information to both the Audit & Risk Committee and the Group CEO.

The following teams are organized under and report to the Group CISO:

• the Group Chief Information Officer ("CIO") Council (headed by the Group CISO and made up of segment CIOs and other specialists) leads and manages the different business segments, which are responsible for the implementation and management of security controls, processes and technology within their respective business segments.
• the Group Cybersecurity ("CS") Leadership team led by the Group CISO and consisting of security officers from each segment, is responsible for decision-making relating to all security topics, defining roadmaps and

execution of strategies and protection within their respective segments.

• the Global Ransomware Crisis Committee made up of various heads of leadership functions such as Legal, IT, Treasury, Communication, Investor Relations and Global Assurance, with the assistance of a third-party service provider acting as the Company's ransomware negotiator and advising partner, is responsible for advancing and implementing the decision-making processes in the event of a ransomware outbreak across the Company and any demands for ransom payments.
• the Data Protection Committee consisting of Group Compliance, Group HR and Group CISO, and led by the Group's Data Privacy Officer, meets quarterly to review any incidents or risks involving data privacy matters, and its recommended actions are implemented across the Group.
• the Cyber Expert Committee ("EC") led by the CISO and made up of various subject matter experts and segment security officers, works as a centralized team to address common global issues and risks, recommend technologies and risk solutions across the Group and prepare technical security proposals to be reviewed by CS Leadership and approved and adopted by the CIO Council.
• the IT Security Council and OT Security Council operating across the Group and comprising security leads from each segment for their respective areas (IT or OT), as well as from Global Assurance are used for purposes of information sharing, feedback sessions for the CS Leadership Group and sounding boards for new proposals coming from CS or EC.

BUSINESS OVERVIEW

Business strategy

ArcelorMittal's success is built on its core values of safety, sustainability, quality and leadership and the entrepreneurial boldness that has empowered its emergence as the first truly global steel and mining company. Acknowledging that a combination of structural issues and macroeconomic conditions will continue to challenge returns in its sector, the Company has adapted its footprint to the new demand realities, intensified its efforts to control costs and repositioned its operations to outperform its competitors. The Company also continues to develop and implement plans aimed at decarbonizing its steel and mining assets in a competitive manner and achieving carbon neutrality by 2050.

Against this backdrop, ArcelorMittal's strategy is to leverage four distinctive attributes in aiming to capture leading positions in the most attractive areas of the steel industry value chain, from mining at one end to distribution and first-stage processing at the other:

• Global scale and scope
• Unmatched technical capabilities
• Diverse portfolio of steel and related businesses, particularly mining
• Financial capability

Three themes

Steel. ArcelorMittal looks to expand its leadership role in attractive markets and segments by leveraging the Company's technical capabilities and its global scale and scope. These are critical differentiators for sophisticated customers that value the distinctive technical and service capabilities the Company offers. Such customers are typically found in the automotive, energy, infrastructure and a number of smaller markets where ArcelorMittal is a market leader. In addition, the Company is present in, and will further develop, attractive steel businesses that benefit from favorable market structures or geographies. In developing attractive steel businesses, ArcelorMittal's goal is to be the supplier of choice by anticipating customers' requirements and exceeding their expectations. It will invest to develop and grow these businesses and enhance its ability to serve its customers. Given the volatile nature of the industry, these investments will be highly disciplined, leveraging advanced project management capabilities, balancing financial and sustainable considerations with targeted strategic opportunities. Commodity steel markets will inevitably remain an important part of ArcelorMittal's steel portfolio. Here, a lean cost structure should limit the downside in weak markets while allowing the Company to capture the upside in strong markets. Finally, ArcelorMittal is developing a strategic response to the challenges and opportunities posed by decarbonization, which it believes will fundamentally change the market structure of the steel industry.

Mining. ArcelorMittal is working to continue to create value from its world-class mining business. Mining forms part of the steel value chain but typically enjoys a number of structural advantages, such as a steeper cost curve. The Company's strategy is to create value from its most significant assets, through selective expansion and de-bottlenecking, by controlling cost and capital expenditure, and by supplying products that are highly valued by steel producers. ArcelorMittal's financial capability has allowed it to continue to invest in key mining assets (in particular AMMC as well as ArcelorMittal Liberia and Serra Azul), while the diversity of its steel and mining portfolio facilitates the ability of the mining business to optimize the value of its products in the steelmaking process. The Company's mining business aspires to be the supplier of choice for a balanced mix of both internal and external customers, while at the same time providing a natural hedge against market volatility for its steel operations. The mining business should also support the decarbonization of the steel footprint through optimization of mining product mix by supplying raw materials needed for the low emissions footprints.

All operations. ArcelorMittal strives to achieve best-in-class competitiveness. Operational excellence, including health and safety, the number one priority, is at the core of the Company's strategy in both steel and mining. The Company steadily optimizes its asset base to ensure it is achieving high operating rates with its best assets. Its technical capabilities and the diversity of its portfolio of businesses underpin a strong commitment to institutional learning and continuous improvement through measures such as benchmarking and best-practice sharing. Innovation in products and processes also plays an important role while supporting overall competitiveness. In addition, ArcelorMittal continues to optimize its decarbonization pathway to ensure that the Company remains competitive and achieves an appropriate return on the required investment.

Five key strategic enablers

Critical to implementing this strategy are five key enablers:

A clear license to operate. Many of ArcelorMittal's businesses are located in regions that are in the early stages of economic development. Practically all are resourceintensive. The Company recognizes that it has an obligation to act responsibly towards all stakeholders. ArcelorMittal's commitment to sustainability and safety is outlined below. See "Business overview—Sustainable development". Sustainability and safety are core values that underline ArcelorMittal's efforts to be both the world's safest steel and mining company and a responsible environmental steward.

A strong balance sheet. The Company maintains a strong balance sheet with credit metrics consistent with investment grade credit rating. This provides a strong foundation for its balanced capital allocation: to invest in organic growth, consistently reward shareholders, and maintain the flexibility, on a selective basis, to pursue acquisitive growth opportunities.

A decentralized organizational structure. ArcelorMittal's scale and scope are defining characteristics that give it a competitive advantage. They also introduce complexity and the risks of inefficiency, bureaucracy and diffuse accountability. To manage these risks, the Company favors a structure in which the responsibility for profit and loss is focused on business units aligned with markets.

Active portfolio management. Throughout the Company's history, it has sought to grow and strengthen the business through acquisitions. That remains the case. The acquisition of existing assets and businesses is typically seen as a more attractive growth path than greenfield investment. The Company is, however, also willing to dispose of businesses that cannot meet its performance standards or that have more value to others.

The best talent. ArcelorMittal's success will depend on the quality of its people, and its ability to engage, motivate and reward them. As detailed below, the Company is committed to investing in its people and ensuring a strong leadership pipeline. See "Management and Employees—Employees— Employee development". It will continue to improve its processes to attract, develop and retain the best talent.

Research and development

The Company's Global Research and Development ("R&D" or "Global R&D") division provides the technical foundation for the sustainability and commercial success of the Company by stimulating innovative thinking and the continuous improvement of products and processes.

The Company operates 14 research sites in 9 countries around the world. In 2024, ArcelorMittal's R&D expense was \$285 million (compared to \$299 million and \$286 million in 2023 and 2022, respectively). In addition, the Company capitalized \$29 million of research and development expenses in 2024 (compared to \$26 million in 2023).

In 2024, R&D launched 20 new products and solutions to accelerate sustainable lifestyles, and 26 products and solutions to support sustainable construction, infrastructure and energy generation.

Among its R&D initiatives, in 2024, the Company undertook a total of 145 Life Cycle Assessment ("LCA") studies related to steel products and the processes used to produce them, all guided by the relevant standards.

For Automotive segment, ArcelorMittal continuously develops its S-in motion® steel solution range, which helps in optimizing passive safety, production costs, and the carbon footprint of the Company's solutions. AHSS products are among the most affordable solutions on the market for both passengers and battery protection. In 2024, new grades of steel were marketed, particularly under the MartInsite® brand. Due to their anti-intrusion performance and fatigue resistance, these grades are particularly well-suited in terms of automotive safety standards which require high impact resistance.

ArcelorMittal Multi Part Integration® (MPI) concept was developed to simplify the vehicle manufacturing process. The Company launched several new projects in 2024 for OEMs, after the initial success of MPI Door-Ring concepts in the U.S. and China with both legacy and newcomer OEMs. In 2024, the Company launched a global advertisement campaign to promote MPI "The Power of Less".

The Company aims to deliver similar breakthrough advances in other sectors by creating differentiated products and unique engineering solutions. ArcelorMittal is fully involved in the development of solutions dedicated to the Global Energy Transition. The Company has developed and patented advanced steels for use in the renewable energy segment. Notably, Magnelis® long lasting coating combined with Hyper® high strength steels have become a material of choice for light weight solar mounting systems. In 2024, new lines started production in India (AMNS India) and Brazil (ArcelorMittal Vega Do Sul). Additionally, the Company is working on the development of solutions suitable for the hydrogen economy, electricity grids, carbon capture, storage & use and bioenergy. Hymatch® steel offer was developed to provide steel grades suitable for H2-linepipes.

The production of a complete range of low-CO2 steels allows for a reduction in carbon footprint by up to 65%. More than 50 new XCarb® Recycled and Renewably Produced ("RRP") products have been commercialized in 2024 and more than 200 other new products are under development.

XCarb® RRP steels (flat, long, tubular, profiles, sandwich panels) have been incorporated in Steligence® building concepts. Steligence® is the holistic platform for environmentally friendly and cost-effective steel solutions for circular use (design for re-use), resilience with respect to exceptional events (floods and storms), as well as solutions for thermal retrofit or solar energy harvesting.

In process research, the focus remains on innovations in the following domains:

By-products and circular economy. In 2024, the Company characterized the production of new steel routes by-products under different operational conditions to foresee the qualities and quantities of the new by-products mix. In 2024, LCA was calculated to compare the use of slag to replace other materials. As an example, Sidercal® is a slag-based steel byproduct used in roads construction in the sub-base and as pavement.

Other circular economy initiatives include working on the use of mining tailings as a secondary raw material, either by finding marketable solutions or generating valuable products to be used in-house and in construction.

Progress against air pollution. In 2024, information of all studies and real data monitoring were analyzed, concluding that control measures implemented in the yards in Tubarão have been effective in reducing dust emissions.

ArcelorMittal also has research activities focused on innovative gas cleaning technologies (Nitrogen Oxides ("NOx"), Sulphur Oxides ("SOx")). In 2024, R&D tests proved significant NOx emissions reduction (up to 50%) at a semiindustrial scale.

Progress in water management. ArcelorMittal is investigating solutions to reduce water vulnerability in some areas. In 2024, R&D initiated a smart pilot plant in Tubarão (Brazil) to monitor basic water quality parameters with a collection of sensors powered by solar energy. This pilot plant delivered promising results during the test phase during the year.

R&D continues supporting ArcelorMittal's three

decarbonization paths for primary activities: The Company's ongoing Volteron™ project is utilizing low temperature iron electrolysis, a first of its kind industrial scale pilot (which is running according to schedule).

In 2024, the Company identified blast furnace decarbonization technologies including top gas recycling and potential CO² storage to reach the expected CO2 decrease. The testing and evaluation with actual BF gases of some carbon capture technologies have been completed at pilot level.

In 2024, advanced models to optimize the energy efficiency of the reheating furnaces were industrialized, reducing energy consumption by 5-10% per furnace. Overall, 23 furnaces at 19 different plants are already equipped with this model.

Process research and development for Products differentiation:

In electrical steels, R&D contributed to the strong progress in reliability and quality at the Company's Saint-Chély (France) electrical steel plant while supporting the new investment in Mardyck (France) Calvert (U.S.).

Mining Process Improvement: To assist with the decarbonization of the Group, the Mining segment and Global R&D are investing significantly in the decarbonization of pellets production. By reducing the temperature of pellets curing and changing the specific binders used for the balling, and therefore modifying the pelletizing process, CO² emissions from the mining business will be reduced.

In addition, Global R&D is de-risking all ArcelorMittal tailings facilities worldwide with the development of its own surveillance platform to monitor in real time the conditions and the impact on planned activities regarding safety.

In the digital area, ArcelorMittal invested early and significantly in automation systems, and for decades the Company has been a pioneer in the introduction and use of artificial neural networks. ArcelorMittal is currently fully committed to a total digital transformation and is progressively becoming a datadriven company.

In 2024, in addition to various internal awards, Global R&D received an important external recognition in the AI domain from International Data Corporation – Future Enterprises Award (Future of Operations) in North America due to an internally developed AI solution which maximizes throughput at AMNS Calvert's slab yard. The plant sustainably manages the targeted increased volumes as slab yard is no longer a bottleneck. This award comes as a close collaboration with AM Calvert's operations.

In 2024, the Company has continued with significant advances aligned with its digital plan and strategy, including the following highlights:

• ArcelorMittal patented new AI algorithms and their applications.
• The Company's significantly mature AI-based product development platform allows speeding up the development of certain families of products and providing solutions to develop new products.
• Internally developed AI algorithms show specific results in predictive maintenance of different types of critical equipment. Global deployment is progressively being realized.
• More traditional and globally deployed advanced process models are being reworked incorporating new AI algorithms.
• Several of the Company's expansion plans are thoroughly modelled in advance combining AI and mathematical optimization techniques to a very high level of sophistication allowing to have very accurate representation of the new investment under many different business scenarios.
• AI-based Production Scheduling optimization continues to remain a primary focus. R&D developed in-house solutions that have outperformed solutions available in the market.

While the implementation of large-scale digital and industry 4.0 projects is challenging in a company of ArcelorMittal's size, once implemented these projects bring major benefits and value because of the Company's scale and global footprint.

Materiality

The starting point for the Company's sustainability reporting and planning is to assess the issues that are most material in their impacts for external and internal stakeholders, against the issues seen by the Company as having the most actual or potential impact on its business and value. Further, the Company also assesses material topics from a financial perspective. This allows the Company to identify priority issues to address and those that are increasing or decreasing in importance. It provides the basis for the Company's sustainability planning and programs including investment decisions, and serves as a benchmark to assess progress.

The Company's most material topics are:

• Safety
• Climate
• People (including equal opportunities and nondiscrimination)
• Air, water, land, biodiversity and ecosystems
• Communities
• Value chains that the Company's stakeholders trust
• Business conduct

Reporting

The Company is committed to reporting on its governance, strategy, risks and performance relating to each of its material issues in its key publications including Annual reports, Climate Action Reports and Sustainability Report.

In 2024, the Company has continued to assess the resilience of the business against different transition and physical climate scenarios and consider the relevant financial implications to inform its strategy and manage its risk exposure.

In 2024, alongside making disclosures to the Carbon Disclosure Project ("CDP") on climate change and water, and conducting numerous customer surveys and investor engagement, the Company published several country-specific sustainability reports as required by its subsidiaries operating in various jurisdictions.

The Company periodically publishes the results of its engagements through its climate advocacy and policy alignment reports on ArcelorMittal's website.

The Company also released its Report on Payments to Governments in Respect of Extractive Activities for the year ended December 31, 2023.

The Company publishes a special disclosure report in compliance with the US Dodd Frank Act Section 1502 and has been working to meet the requirements of the EU's conflict minerals regulation.

Health and Safety

ArcelorMittal's operations are subject to a broad range of laws and regulations relating to the protection of human Health and Safety ("H&S"). As these laws and regulations in the United States, the EU and other jurisdictions continue to become more stringent, ArcelorMittal expects to expend substantial amounts to achieve or maintain compliance. ArcelorMittal has established H&S guidelines requiring each of its business units and sites to comply with all applicable laws and regulations. Compliance with such laws and regulations and monitoring changes to them are addressed primarily at the business unit level, checks are made through a 3-line of assurance model. ArcelorMittal has a clear and strong H&S Management System, that includes specific policy, standards and life-saving golden rules, aimed at reducing on a continuing basis the severity and frequency of accidents; through its Group H&S Council ("GHSC"), the Company reinforces the penetration of the safety culture in the Company. The effective policy outlines the commitment ArcelorMittal has made to the H&S of all employees and reinforces the accountability of the local management and encourages the continuous improvement in H&S performance at unit level, which permits the GHSC to define and track performance targets and monitor results from every business unit and site.

Safety governance

ArcelorMittal business units CEOs are accountable for the segment/unit H&S performance. Business unit CEOs and local safety departments integrate safety into the business strategy, manage and implement the Group's best practice procedures and standards at the local level. Further, ArcelorMittal business units solicit external expertise and resources in closing any gaps in improving the safety performance.

The Head of Corporate H&S, who is also a member of the Group Management Committee, reports to the Executive Vice President, Head of Corporate Business Optimization, who in turn reports to the CEO of ArcelorMittal. The corporate H&S team develops, maintains and promotes the Group H&S strategy, management system and defines and tracks safety KPIs, monitoring results from every business unit and site. ArcelorMittal has an established Group H&S policy and standards that each of its business units and sites are required to comply. Key elements of the policy include:

• All fatalities and work-related illness can and must be prevented; H&S always comes first in all decisions and actions at all levels of the Group.

• Enhanced emphasis on management's role while recognizing and reinforcing that all employees need to be actively involved in H&S management. Making it clear that working safely is a condition of employment for everyone at ArcelorMittal.
• Explicitly stating that everyone is empowered to act and stop work if they see a situation which they deem to be unsafe.
• Stressing the need to report and analyze all incidents, so that employees and management learn from them across the Company.
• Highlighting the role effective management systems and sharing of best practices has in driving continuous improvements.

Further oversight of safety performance is provided by the GHSC which is chaired by the Head of Corporate H&S. This committee provides governance, oversight, alignment of H&S initiatives and ensures best practice is shared across all segments.

In June 2022, the executive Short-Term Incentive Plan ("STIP") was linked to the frequency of proactive Potential Serious Injury and Fatality events ("PSIFs") rates with a fatality frequency rate circuit breaker. The proportion of bonuses linked under this scheme to safety was increased from 10% to 15% in 2021. Safety performance also represents 10% of the Long-Term Incentive Plan.

ArcelorMittal dss+ workplace safety audit In October 2024, the Group published the recommendations

of the comprehensive dss+ safety audit that was commissioned at the end of 2023.

The audit, which was ongoing for nine months across all geographies, functions and levels of the organization, had three main scopes:

• Fatality prevention standards for the three main occupational risks leading to serious injuries and fatalities (work at heights, vehicle driving ad energy isolation);
• Process Safety Management ("PSM") focused on the highest risk assets; and
• In-depth assessment of H&S systems, processes and capabilities; governance and assurance processes; and data management

It was a comprehensive audit with dss+ having unprecedented access across the Group from the Board to the shop floor. Specifically, 155 sites (including joint ventures), were audited for the FPS compliance and 14 highest risk assets were audit for the PSM. For the H&S management systems and governance and assurance reviews, more than 280 employees including the Board of Directors, senior and middle management, H&S personnel, and contract employees were interviewed. Further, the auditors attended more than 60 management and H&S meetings; and conducted more than

80 focus group sessions with shop floor employees (union and non-union), supervisors and middle management.

dss+ presented its recommendations to the Company's Board of Directors, the Executive Office and the Group Management Committee. Overall, while there are areas of excellence in the Group, variability in performance exists which must be addressed by initiatives that fast-track the strengthening of "one safety culture," underpinned by enhanced governance and assurance across all operations.

The recommendations were focused on six main areas:

• 1 Improving the identification and understanding of operational risk exposure: Strengthening the identification and understanding of operational risk exposure by enhancing the governance framework to better identify and understand operational risk exposures and building on the existing fatality prevention standards to upgrade the "Plan Do Check Act" (PDCA) cycle, supported by additional governance practices (e.g., additional leading indicators and enhanced risk-management routines).
• 2 Strengthening the existing health & safety assurance model: Strengthening the assurance model with threelines of assurance, and operationalizing the model through regular assurance reviews.
• 3 Continuing to embed safety values, mindsets and behaviors to strengthen the "one safety culture": On-theground coaching and mentorship programs for all leaders (involving more than 10,000 people) to reinforce the existing safety training programs.
• 4 Improving contractor safety management standards: Standardizing and improving each contractor safety management element (e.g., contractor selection, evaluation, onboarding, execution and post-performance review) across all contractor cohorts (embedded and projects contractors) to bring any lagging contractor safety performance up to ArcelorMittal's standard requirements.
• 5 Adopting industry best practices for PSM: Developing and implementing a common PSM framework and accompanying standards that further incorporates best practices in all relevant PSM elements while ensuring alignment with relevant management systems (e.g., operations and maintenance) to improve controls effectiveness and mitigate process safety-related risk.
• 6 Integrating H&S elements into supporting business processes: Further integrating supporting business processes into H&S with a focus on four processes: a) further integrate safety elements into all parts of the employee life cycle encompassing selection, onboarding, development and promotion; b) consistently rewarding and recognizing good performance and achievements, and increase consequences for not following processes and rules, e.g. consequence management; c) further enhance the identification of critical safety investments to

support risk reduction efforts; and d) strengthening safety management practices throughout capital projects life cycle, from design, engineering, procurement, and contracting, to construction and start-up, including governance and assurance framework.

Business specific plans have been developed to implement the recommendations of the dss+ safety audit and to be incorporated into the five-year planning cycle. Key highlights of the progress to date include:

• The new Process Safety Framework has now been launched with a first wave of 12 assets.
• The H&S assurance model has been strengthened, with three lines of assurance across all business units, to provide more comprehensive oversight starting in the first quarter of 2025. The third line will directly report to the Board Audit and Risk Committee.
• Progress in the development of 'One Safety Culture' across the Group will be measured in June 2025.
• Consequence management standards are becoming stronger across the Group as a result of the Company's 'Just and Fair Expectations' rolled out in January 2025. Furthermore, the Company is tracking and auditing the compliance of local policies mirroring these expectations. It also continues to strengthen the health and safety focus in all its human resource processes and practices.

Performance in 2024

In 2024, there were 13 fatalities in 13 events, of which 6 were ArcelorMittal employees and seven were contractors. The Company fatality frequency rate ("FFR") was 0.03; and Lost Time Injury Frequency Rate ("LTIFR") was 0.70.

The Company has not delivered the progress on safety for which it had hoped in 2024. The whole Company is working hard on the dss+ audit recommendations and it is now moving from the planning phase to full implementation in 2025. This combined with swift action taken by business unit CEOs where issues are identified will support the Company in its journey to zero fatalities.

6 of the 13 fatalities were in the EU region which comprises Europe Flat Products, Europe Long Products and the European operations of Sustainable Solutions. Within the EU region, the Europe Flat Products operations were fatality-free for the first time in 2024 while the Europe Long Products operations had 4 fatalities after a period of two years with no fatalities.

The fatalities within Europe Long Products have led to immediate action taken across this part of the business. All site CEOs stepped back from operational role duties for a period of four weeks to focus 100% of their time on safety at their site, led by the ArcelorMittal Europe Long Products CEO, who decided to take on the additional role of Head of H&S, which continues today. During this period, all site CEOs were required to put together and publish a Workplace Safety

Assessment roadmap with clear actions and accountabilities. This four-week period, culminated in all site CEOs and H&S heads attending a two day seminar to present their roadmap (which incorporates the dss+ recommendations) and share best practices. The roadmaps are now in execution mode and are tracked on a bi-weekly basis with every site by the ArcelorMittal Europe Long Products CEO. ArcelorMittal continues working harder towards its zero fatality goal and has already seen some encouraging signs that the leading

indicators are starting to move in the right direction across the Group. The proactive PSIFs rate is now starting to stabilize at between 16.5 and 17. This demonstrates the maturity of this measure and emphasizes the improvement seen in the safety processes and culture. Furthermore, ArcelorMittal employees were certified on the Life Saving Golden Rules in 2024. The certification is designed to raise awareness of the importance of these rules and will be rolled out to regular contractors during the first half of 2025.

Climate change and decarbonization

Along with safety, climate change is a top material sustainability issue for ArcelorMittal. Since 2018, total absolute emissions of the Company's operations have reduced by 86 million tonnes CO2 (approximately 46%), primarily due to footprint and asset optimization of some of ArcelorMittal's most CO2 intensive capacity. In 2024, EAFs comprised 25% of the Group's global production, as compared with 19% in 2018.

ArcelorMittal's progress and activities related to decarbonization have been across four key areas:

• Disciplined, competitive decarbonization capital expenditures
• Securing the resources for the transition
• Fostering the development of a supportive environment for decarbonization, and
• Enabling the transition of key sectors.

The Company remains committed to achieving net-zero by 2050. Given the recent announcements made by the Company regarding its decarbonization plans in Europe, the 2030 intensity targets are under review and will be set out in the forthcoming Climate Action Report 3.

Disciplined and competitive decarbonization

ArcelorMittal's previously announced decarbonization investments in Europe are progressing at a slower pace than initially envisioned. The previously announced intention to replace several blast furnaces with lower carbon emissions "hydrogen ready" DRI-EAF facilities was premised on a favorable combination of policy, technology and market developments that would help offset the significantly higher capital and operating costs involved. Progress so far has been insufficient to support the investment case. The Company expects several important developments in 2025, including the scheduled review of the CBAM, an anticipated review of the

steel safeguards (necessary to protect the industry from unfair trade resulting from China's excess capacity), and the publication of the Steel and Metals Action Plan amongst others.

The Company continues to optimize its decarbonization plans, focused on achieving an acceptable return on the capital to be invested. Whilst the Company awaits more support and policy progress in Europe, it is continuing with engineering work, as well as analyzing a phased approach that would first start with constructing EAFs, which can also be fed with scrap steel to significantly reduce emissions.

The Company has three announced EAF projects that are already progressing in Gijón (Spain) (see "Introduction— Sustainable developments highlights"), Sestao (Spain) and at its joint venture AMNS Calvert (USA), the latter which is now commissioning. Overall, ArcelorMittal has invested \$1 billion decarbonization capital expenditures since 2018, mainly in EAF investments, DRI/EAF engineering studies and CCUS pilots.

Gijón, Spain

ArcelorMittal has started the construction of an EAF for long products at its Gijón plant, which is expected to produce its first heat in the first quarter of 2026. This investment of €213 million will be the first major EAF project to be implemented within the Company's decarbonization program in Europe and will constitute the first step towards low-carbon emissions steelmaking in Asturias. See "Introduction— Sustainable developments highlights".

Sestao, Spain

Sestao is in an advantageous position as very few producers in Europe are capable of producing low-carbon emission flat steel via the EAF route today. There has been good progress with the Company's efforts to increase production to 1.6 million tonnes by 2026 at its flat products plant in Sestao

where it has two EAFs. Once complete, much of this production will be XCarb® RRP low-carbon emissions steel.

Sestao is also Europe's first Compact Strip Production ("CSP") mill line that combines continuous casting, heating and rolling of slabs, and the plant can produce steel from melting start to coiling finish in approximately 3 hours. This type of plant benefits from energy saving compared to conventional production, due to its simplified and shortened production cycle minimizing reheating needs.

AMNS Calvert, USA

The joint venture has invested in a new 1.5 million-tonnes EAF, see "Properties and capital expenditures—Capital expenditures".

Securing the resources for the transition

ArcelorMittal has been investing in key resources to support the decarbonization of the Group including renewables and high quality metallics.

Access to clean electricity

Grid decarbonization in countries where the Company operates has helped its CO2 footprint over the past few years, especially in countries with high renewable penetration (for example Spain, France and Canada), although the overall impact has been limited. As countries continue to accelerate clean energy deployment and build the additional grid infrastructure needed as part of their climate goals, further progress is expected.

The Company is also investing in secure access to renewable energy by developing its own renewable energy projects, in regions where competitive projects can be developed due to the high quality of natural resources and enabling conditions in place (grid infrastructure, supporting policies, etc.). Currently, the Company has a 2.1GW renewable energy portfolio:

AM Green Energy

The Company is investing in developing renewable projects that will help with the decarbonization of AMNS India. A \$0.7 billion investment in the 1 GW renewable energy project launched in 2022 by ArcelorMittal. The project integrates solar and wind power generation, coupled with energy storage solution through a co-located pumped hydro storage plant, which helps to overcome the intermittent nature of wind and solar power generation. The project is owned and funded by ArcelorMittal. AMNS India entered into a 25 year off-take agreement with ArcelorMittal to purchase renewable electricity annually from the project, resulting in over 20% of the electricity requirement at AMNS India's Hazira plant coming from renewable sources, reducing carbon emissions by approximately 1.5 million tonnes per year. 100% of the solar modules and 96% of the wind turbines have already been installed. The project has begun commissioning in a phased manner and has started supply of renewable power to AMNS India. The Company is studying various options to develop subsequent phases to further increase renewable electricity capacity in India. See "Properties and capital expenditures— Capital expenditures".

ArcelorMittal Argentina

In Argentina, ArcelorMittal has developed a partnership with PCR for a 130MW solar and wind capacity project, which is already operational and supplies over 30% of ArcelorMittal's local electricity requirements, and a 180 MW wind project to be completed by 2027 with a total investment of \$255 million.

ArcelorMittal Brazil

In 2024, in addition to the joint venture agreement with Casa dos Ventos signed in 2023 for the development of a 554MW capacity wind power project (see "Properties and capital expenditures— Investments in joint ventures"), ArcelorMittal Brazil signed contracts for the development of two solar energy projects with a combined capacity of 465MW, equivalent to 14% of its current electricity requirements see "Introduction— Sustainable developments highlights".

Securing metallics input

The main challenge when it comes to raw materials for low carbon emissions steelmaking (high-quality iron ore for DRI production or high-quality scrap, both to be used as input in EAFs) is their availability. The first (high-quality iron ore) represents only about 4% of global iron ore supply and scrap is a scarce resource in many regions. Accordingly, the key actions the Company is taking in this area are focused on securing and diversifying the supply of high-quality raw materials by expanding existing operations and acquiring new businesses.

AMMC

In 2021, the Company announced that a CAD\$205 million investment, supported by the Quebec government, would enable AMMC to convert its entire 10 million tonnes per year pellet production to DRI pellets. The project is in the construction phase and is expected to be completed by the second quarter of 2026. It is expected to become one of the world's largest producers of DRI pellets, the raw material feedstock for iron-making in a DRI furnace. The project includes the implementation of a flotation system that is expected to enable a significant reduction of silica in the iron ore pellets, facilitating the production of very high-quality pellets. It is also expected to deliver a direct annual carbon emissions reduction of approximately 200,000 tonnes at AMMC's Port-Cartier pellet plant, equivalent to over 20% of the pellet plant's total annual carbon emissions.

ArcelorMittal Texas HBI

In 2022, the Company secured high-quality metallic feedstock and purchased a majority shareholding in a world-class HBI plant in Texas (USA). The plant has a 2 million tonnes production capacity. HBI is a high-quality feedstock made through the direct reduction of iron ore which is used to produce high-quality steel grades in an EAF, but which can also be used in blast furnaces, resulting in lower coke consumption. The facility is state-of-the-art, built with best-inclass technology and equipment supplied by MIDREX Technologies. Its coastal location with access to a deep shipping channel allows for cost effective transportation. It also has the advantage of unused land that provides options for further development for additional HBI capacity.

Increasing access to high quality scrap

ArcelorMittal is already one of the biggest recyclers of steel in the world, recycling around 19 million tonnes of scrap every year.

As part of the Sustainable Solutions segment, the recycling business oversees the acquisition and processing of scrap, supplying recycled steel to ArcelorMittal's EAFs and offering closed loop model to customers. In 2022 and 2023, the Company acquired three recycling business: John Lawrie Metals, Alba International Recycling, and Riwald Recycling with a processing capacity of almost 1 million tonnes of scrap steel.

Investing in innovative and breakthrough technologies

The Company is already operating several commercial-scale projects to test and prove a range of CCUS technologies and is also partnering with different stakeholders in the value chain to overcome challenges to deploy these solutions at scale.

CCS Carbon Hub in Ghent, Belgium

ArcelorMittal started a feasibility study for the Ghent Carbon Hub project in partnership with North Sea Port and energy infrastructure group Fluxys. The Ghent Carbon Hub will be an open-access hub to transport and liquefy CO2 from emitters, provide buffer storage and load the CO2 onto ships for onward permanent storage. The project should have the capacity to process 6 million tonnes of CO2 per year – equivalent to around 15% of Belgium's industrial CO2 emissions. North Sea Port, a 60 kilometer-long cross border port in Belgium and the Netherlands, is home to a cluster of energy intensive industries with a significant CO2 footprint. In late 2022, the project was awarded a €9.6 million grant from the EU Commission's Connecting Europe Facility for Energy (CEF-E) funding program.

MHI carbon capture plant: capturing and storing off-gases from the steelmaking process

Also in Ghent, the Company has partnered with Mitsubishi Heavy Industries (MHI), BHP and Mitsubishi Development for a pilot carbon capture project to test the capture of off-gases from the blast furnace at a rate of 300kg of CO2 per day in an initial phase, using MHI's proprietary carbon capture technology. The project, which has been operational since May 2024, will also involve a second phase that involves testing the separation and capture of CO2 in hot strip mill offgases (and potentially on DRI).

3D DMX™: capturing and storing blast furnace waste gas for transporting and storage in Dunkirk, France

In Dunkirk (France), a successful CCS pilot project has been completed, using low temperature heat to separate CO2 from other blast furnace off-gases at a capture rate of 0.5 tonnes of CO2 per hour. The project, which started in April 2023, successfully achieved high capture rates.

Steelanol CCU plant

The Steelanol facility at ArcelorMittal's steel plant in Ghent (Belgium) reached full operational capacity in November 2023 and is currently converting carbon-rich industrial emissions from its blast furnace into fuel-grade ethanol by using leading carbon recycling technology developed by LanzaTech. The produced ethanol can be sold directly into fuel markets, or further purified or converted for use in a wide array of consumer products such as apparel, personal care, and packaging. In December 2024, LanzaTech took title to the first barge shipment, which is purified and sold to LanzaTech's CarbonSmart customers in fragrance and home care markets.

The Company is also investing in technologies that can become a leading option for very low carbon emission steel production:

Direct electrolysis

ArcelorMittal is making progress in commercializing direct electrolysis technology. In June 2023, ArcelorMittal and John Cockerill announced plans to construct the world's first industrial scale low temperature iron electrolysis plant. The project is running according to schedule.

XCarb® innovation fund

The Company has continued its investments in innovative breakthrough decarbonization technologies that hold strong potential to decarbonize steelmaking operations. In July 2024, the Company announced the selection of three start-ups as the joint winners of its inaugural XCarb® India Accelerator Program focused on CCUS technologies and biochar production. In September 2024, the Company announced the investment of \$5 million in Utility Global, a company that has developed a patented reactor which processes variable industrial process gases, without the use of electricity, into high-purity hydrogen and a concentrated CO2 stream that can be captured and stored.

Fostering the development of a supportive environment Due to the scale of transformation required in the global economy to achieve net-zero, policy making has a critical role to play. The significant capital expenditure needed to transition to low carbon technologies, and their higher operating costs especially in the EU, needs to be addressed by governments through incentivization of markets and funding and economic support. ArcelorMittal has actively engaged and continues to do so with governments, policy makers and related organizations and interest groups, to build the appropriate policies and economic and social conditions to achieve the changes required in a commercially viable manner.

ArcelorMittal believes that it is crucial that the newly announced policy initiatives of the new European Commission in the January 29, 2025 Competitiveness Compass Communication – including but not only the Clean Industrial Deal and the Steel and Metals Action plan:

• Result in increased trade protection against massive global excess capacity and unfair competition and more robustly enforced trade defence instruments

• Ensure a solution for competitiveness of EU exports, e.g., through an ETS rebate, ETS exemption or continuation of free allowances for export volumes
• Considerably strengthen the CBAM to avoid carbon leakage and circumvention by major redirection of low carbon steel towards Europe without global emission reduction (resource shuffling)
• Include access to sufficient affordable energy
• Include technology neutral simplified funding processes for large scale decarbonization investments
• Support the demand for low-carbon steel through low carbon steel lead markets.

The global investor community is playing a key role in providing the support and finance for the net-zero transition. Climate is a key part of ESG governance that is causing a greater focus on and scrutiny of key performance data such as carbon emissions reduction. Investors are increasingly aligning their portfolios with the goals of the Paris Agreement, often using third-party ratings and proxies to do so. ArcelorMittal continues to engage with such initiatives to ensure that the challenges and opportunities of competitively transitioning multiple steelmaking assets across multiple regions into a low carbon economy are clearly understood and that the approaches adopted are realistic and pragmatic.

The Company is focused on engaging with numerous other important strategic initiatives that gather key stakeholders to identify the main challenges and requirements for the steel sector's transition. These include the Energy Transition Commission (ETC), Industry Transition Accelerator (ITA), World Business Council for Sustainable Development (WBCSD), Organization for Economic Cooperation and Development (OECD), World Trade Organization (WTO), World Steel Association and ResponsibleSteelTM, amongst others.

Enabling the transition of key sectors.

Delivering low-carbon emissions steel solutions In March 2021, the Company launched XCarb®, which at the time was the only low-carbon emissions steel offering on the

• market. The two initial products were: • XCarb® green steel certificates. These agglomerate
• savings from interventions in the steelmaking process made specifically to reduce carbon emissions such as capturing coke-oven gas and re-injecting it into the blast furnace or reducing coal use through natural gas injection in the blast furnace. The savings are then passed on to customers alongside their physical steel purchases, enabling them to report an equivalent reduction in their Scope 3 emissions.
• XCarb®RRP. This is a physical low-carbon emissions steel product made in an EAF powered entirely by renewable electricity, with high levels of recycled steel as the metallic input.

The Company continues to lead the market with sales of XCarb® low-carbon emissions steel, which have a carbon footprint of as low as 300kg per tonne of steel produced. XCarb® sales increased from 0.2 million tonnes in 2023 to 0.4 million tonnes in 2024. The Sestao revamp project is expected to materially increase the Company's ability to produce lowcarbon emissions flat products.

ArcelorMittal is also actively managing its product portfolio to ensure that it is well positioned to capture areas of growth, focusing on strategic higher value-added products. The Company is increasing its portfolio of climate solutions (electrical steels, renewables, insulation, sheet piles) to support customers in key sectors of the low carbon economy. Key examples include:

• Hydrogen: On August 1, 2024, ArcelorMittal launched the steel brand HyMatch® for hydrogen transport pipelines and supporting the implementation of hydrogen infrastructure globally
• Electric Vehicles: On February 6, 2025, ArcelorMittal announced a project to construct an advanced manufacturing facility in Calvert, Alabama see "Introduction— Sustainable development highlights". This builds upon the facility under construction in Mardyck (France) which will produce 170,000 tonnes and the existing site in France at Saint-Chely d'Apcher (80,000 tonnes)
• Low carbon emissions buildings: On May 31, 2024, ArcelorMittal announced that it was adding to the existing portfolio in lightweighting insulation panels through acquisitions of Italpannelli's Italian and Spanish businesses. Combined, the two facilities operate seven production lines with a capacity of thirteen million m² of sandwich panels a year.

These solutions build on those already available across the group in low-carbon emissions buildings (e.g. Steligence brand), renewables (e.g. Magnelis® for solar) and flood protection (EcoSheetPile™ Plus range).

The role of standards in driving demand for low-carbon emissions steel

In line with its intention to lead developments in decarbonization, ArcelorMittal published a concept for a lowcarbon emissions steel standard in June 2022 to help incentivize the decarbonization of steelmaking globally and support the creation of market demand for physical steel products which would be classified as lower, and ultimately near-zero, carbon emissions steel. The concept involves:

• A dual scoring system which provides customers with a LCA value alongside a rating system which measures a company's progress towards near-zero
• Incentivizing the decarbonization of both primary and secondary steelmaking
• Providing transparency and consistency across steel products for customers

• Supporting the development of markets for lowcarbon emissions steel

The Company believes that the creation of clear definitions for low-carbon emissions physical steel is an important component of 'demand pull' and 'supply push' mechanisms that are required to support the steel industry in its transition to net-zero by 2050. Clear definitions will also help inform targeted policy to support the scale-up and commercialization of these near-zero technologies.

These views concur with those of several credible independent bodies, including the Centre for Climate Aligned Finance, The Energy Transitions Commission, The International Energy Agency, which have all published proposals on this topic, and ResponsibleSteel™, which has launched a certifiable standard. The Company also endorsed the World Trade Organization's Steel Standards Principles that were launched at COP28.

Climate governance and risk management

Structures and decision-making

ArcelorMittal's climate-related activity and progress continues to be overseen by a robust governance structure that includes an executive-level Climate Change Panel and Board-level Sustainability Committee chaired by an independent nonexecutive director. The Board also decided to link executive remuneration to the achievement of the Company's climate objectives. Since 2021, decarbonization targets are part of the performance criteria for vesting of the performance share units in the long-term incentive plan.

In terms of investment decision-making, each major capital expenditure project proposal is required to demonstrate its carbon impact as part of the project review to the IAC. The IAC makes all necessary considerations to maximize the business' chances of achieving its targets while ensuring each project is economically justifiable and earns its cost of capital. It is a crucial part of the Company's strategy to manage risk and deliver long-term growth.

Climate-related risks and opportunities

ArcelorMittal conducted an assessment to identify risks and opportunities arising from the transition to a low-carbon economy. The approach included examining key regions of operation and offering a forward-looking review. It considered scenarios aligned with external reference scenarios as shown in the resilience analysis section.

The assessment of transition-related climate risks and opportunities was conducted at a regional/country level and categorized into various groups: policy and legal, technology, reputation, resilience, products, and market. The strategic relevance for each risk and opportunity identified was determined through a qualitative assessment, considering the potential impact to relevant financial indicators, like capital expenditures, operational expenditures, revenue, and access to capital. Where relevant, the impact on profitability or investment value was also considered.

The scenarios used to inform the identification and assessment of physical and transition risks were the following:

	1.5C scenario	<2C scenario	Business as usual	High Emissions
Temperature by 2100	1.5°C	Below 2°C	>2°C	>4°C
External reference scenarios	IEA NZE	IPCC SSP1-2.6, IEA APS/ SDS	SSP2-4.5 and IEA STEPS	IPCC SSP5-8.5
Description	• Holds warming to approximately 1.5°C, aligned with the Paris Agreement. • Steel demand by 2050 projected at 2 Gtonnes per year	• Assumes a strong global commitment to reducing GHG emissions, leading to low levels of warming • Steel demand by 2050 projected between 2.1 and 2.7 Gtonnes per year	• Assumes moderate efforts to reduce GHG emissions and balanced outcome in terms of socio-economic development and climate change impacts • Steel demand by 2050 projected between 2.2 -2.7 Gtonnes per year	• Assumes GHG emissions continue to rise, leading to high levels of warming and significant climate change impacts
Used for physical risks assessment	No	Yes	Yes	Yes
Used for transition risks/ opportunities assessment	Yes	Yes	Yes	No
Used for target analysis and decarbonization plan	Yes	Yes	Yes	No

These scenarios were used to conduct screenings to qualitatively identify material climate-related risks and opportunities. Main results are summarized below:

Transition risks and opportunities

For the transition screening assessment, the Company used three scenarios: 1.5°C, below 2°C and business as usual to stress-test the exposure to transition climate risks.

Material climate change related transition risks and opportunities, are summarized below. The results are for 2030 under the 'below 2C' and the '1.5C' scenarios, as these capture the most significant transition impacts:

• Regulatory and Policy related risks: see "Introduction— Risk Factors and Control— Laws and regulations restricting emissions of greenhouse gases could force ArcelorMittal to incur increased capital and operating

costs and could have a material adverse effect on ArcelorMittal's results of operations, financial condition and reputation".

• Opportunities arising from enabling low-carbon transition in key sectors: Low-carbon transition within the Company's core customer sectors presents an opportunity to improve and/or expand the product portfolios to meet customers' requirements. Some example of this include electrical steel for electric motors used to power battery electric vehicles; plug in hybrid electric vehicles and hybrid vehicles; low-carbon steel products; HyMatch® for hydrogen transport pipelines and supporting the implementation of hydrogen infrastructure. Refer to 'Enabling the transition of key sectors' covered above.

Physical risks

ArcelorMittal conducted further analysis of its climate change related physical risks in 2024 to assess exposure of its assets to climate hazards. A total of 170 assets, including mining, iron and steelmaking, downstream processing, recycling, and forest management sites, were covered. To conduct this assessment, a third-party climate data analytics tool was used to analyze the exposure of assets to flood, extreme precipitation, heat, cold, fire, drought, wind, and hail related risks.

This analysis considered three IPCC scenarios and was based at the asset-specific geospatial coordinate levels. Climate hazards were evaluated over three-time horizons: short-term (2025), medium-term (2030), and long-term (2050). The short- and medium-term time horizons align with ArcelorMittal's 5-year strategic planning, while the long-term horizon covers the lifespan of most assets.

The three key risks identified included:

• Heat stress, concentrated primarily in the tropical and subtropical regions where high temperatures are already common and are likely to worsen (Mexico, Brazil, Liberia and India). Heatwaves can also have a significant impact in Europe.

• Flood exposure risk mainly concentrated in the Northern Europe region, specifically in areas located in close proximity to rivers or in coastal areas. Sites in Mexico, Brazil, India and Europe have severe to high exposure to precipitation, which also presents flooding risk.
• High water stress caused by a combination of high heat and low precipitation primarily concentrated in the Northern Europe, North America, Southern Africa and South Asia regions.

Since this assessment, the Company has conducted segmentlevel capacity building training exercise to increase awareness about the results of this assessment and the key principles to be considered for site-specific plans to reduce such risks.

Carbon performance (based on 2024 data)

In 2024, the Company's adjusted group intensity KPI was 1.75 tonnes of CO2 emissions per tonne of crude steel ("tCO2e/ tcs"). Significant reductions are only likely to be made with the successful deployment of steelmaking and energy transformation projects. In order to view the trend for CO2e intensity of steel only, the Company also reports the data for 2018, adjusted for structural changes to its portfolio to enable a like for like annual comparison. This shows a reduction of 5.4% since 2018, from 1.85tCO2e/tcs to 1.75tCO2e/tcs. The Company saw a 5.0% improvement in 2024, down to 1.62tCO2e/tcs from the 2018 baseline of 1.71tCO2e/tcs for its European adjusted KPI – CO2e intensity of its steel operations (Scopes 1 and 2). The adjusted absolute emissions that correspond to the Company's global target KPI (Scope 1 and 2, steel and mining) decreased by 25% compared with 2018.

The following indicators are used to measure and monitor ArcelorMittal's decarbonization progress:

Metric	Unit	Scope + perimeter	2018	2022	2023	2024	2018-2024 Reduction
Adjusted absolute CO2e footprint1	Million tonnes	ArcelorMittal Scope 1+2	136.3	106.2	98.5	101.9	25 %
Adjusted absolute CO2e footprint1	Million tonnes	Europe Scope 1+2	67.6	54.5	48.4	51.5	24 %
Adjusted Group CO2e intensity KPI1 (steel and mining)	tCO2e/tonne of steel	ArcelorMittal Scope 1+2	1.85	1.82	1.78	1.75	5.4 %
Adjusted Europe CO2e intensity KPI1 (steel)	tCO2e/tonne of steel	Europe Scope 1+2	1.71	1.71	1.68	1.62	5.0 %
CO2e intensity steel only2	tCO2e/tonne of steel	Steel Scope 1+2+ limited scope 3	2.09	1.98	1.96	1.87	10.7 %
Adjusted CO2e intensity1,2 steel only	tCO2e/tonne of steel	Steel Scope 1+2+ limited scope 3	1.95	1.88	1.86	1.87	4.3 %

1. These figures have been retrospectively adjusted for structural changes to the ArcelorMittal portfolio in the previous 12 months, and reflect emissions and production for ArcelorMittal's site portfolio as at December 2024 to enable a like for like annual comparison.

2. This indicator includes limited upstream Scope 3 emissions from purchased goods that a steelmaker would normally be expected to produce, such as coke, slabs, burnt lime in order to maintain a consistent system boundary and so a like for like comparison.

Ongoing focus on tailings dam safety

Tailings dam safety and structural integrity is a critical issue for all mining companies, in order to protect the safety of local

communities and employees, and to protect the environment from pollution and flooding. The Company has developed a

tailings governance framework based on the Mining Association of Canada (MAC), the Canadian Dam Association (CDA) and the Global Industry Standard for Tailings Management (GISTM). The aim is to ensure that all Group tailings facilities are structurally sound and safe, with all efforts directed at minimizing risk, including independent audits benchmarked against these international guidelines.

ArcelorMittal manages a total of 27 tailings storage facilities ("TSF"). These include conventional, paste, dry and in-pit facilities. There are 15 active, 1 dormant, 4 in care and maintenance, 3 in closure and 4 under construction facilities. To ensure their ongoing safety, a formal assurance process is in place that includes internal and external audits. This is supported by a continuous improvement program that reduces the Company's risk of existing conventional operations by promoting reduced moisture disposal methodologies (e.g. high-density thickened tailings or filtered tailings where appropriate) and proven new technologies (e.g. high-precision radar, InSAR satellite monitoring and remote instrumentation) to monitor facilities globally in real time. The Company is assessing all its mining operations for transition in line with these principles and developing customized design solutions for non-conventional tailings system management.

Tailings thickening steps have been implemented in assets in Mexico, reduced moisture disposal methodologies in Brazil and Canada, and further studies are ongoing across a range of operations.

Products and markets

Product overview

Information regarding segment sales by geographic area and sales by type of products can be found in note 3 to ArcelorMittal's consolidated financial statements.

ArcelorMittal has a high degree of product diversification relative to other steel companies. Its plants manufacture a broad range of finished and semi-finished steel products with different specifications, including many complex and highly technical and sophisticated products that it sells to demanding customers for use in high-end applications.

ArcelorMittal's principal steel products include:

• semi-finished flat products such as slabs;
• finished flat products such as plates, hot- and coldrolled coils and sheets, hot-dipped and electrogalvanized coils and sheets, tinplate and color coated coils and sheets;
• semi-finished long products such as blooms and billets;
• finished long products such as bars, wire-rods, structural sections, rails, sheet piles and wireproducts; and
• seamless and welded pipes and tubes.

ArcelorMittal's main mining products include iron ore lump, fines, concentrate, pellets and sinter feed.

Steel-making process

Historically, primary steel producers have been divided into "integrated" and "mini-mill" producers. Over the past few decades, a third type of steel producer has emerged that combines the strengths of both the integrated and the mini-mill processes. These producers are referred to as "integrated mini-mill producers".

Integrated steel-making

In integrated steel production, coal is converted to coke in a coke oven, and then combined in a blast furnace with iron ore and fluxes to produce hot metal. This is then combined with scrap in a converter, which is also referred to as basic oxygen furnace ("BOF"), to produce raw or liquid steel. Once produced, the liquid steel is metallurgically refined and then transported to a continuous caster for casting into a slab, bloom or billet or cast directly as ingots. The cast steel is then further shaped or rolled into its final form. Various finishing or coating processes may follow this casting and rolling. Recent modernization efforts by integrated steel producers have focused on cutting costs through eliminating unnecessary production steps, reducing manning levels through automation, and decreasing waste generation. Integrated mills are substantially dependent upon iron ore and coking coal which, due to supply and demand imbalances, shortening of contract durations and the linkage between contract prices and spot prices, have been characterized by price volatility in recent years.

Mini-mills

A mini-mill employs an electric arc furnace to directly melt scrap and/or scrap substitutes such as direct reduced iron, thus entirely replacing all of the steps up to and including the energy-intensive blast furnace. A mini-mill incorporates the melt shop, ladle metallurgical station, casting, and rolling into a unified continuous flow. The quality of steel produced by mini-mills is primarily limited by the quality of the metallic raw materials used in liquid steel-making, which in turn is affected by the limited availability of high-quality scrap or virgin orebased metallics for use in the electric arc furnaces. Mini-mills are substantially dependent on scrap, which has been characterized by price volatility in recent years, and the cost of electricity.

Integrated mini-mills

Integrated mini-mills are mini-mills that produce their own metallic raw materials consisting of high-quality scrap substitutes, such as DRI. Unlike most mini-mills, integrated mini-mills are able to produce steel with the quality of an integrated producer, since scrap substitutes, such as DRI, are derived from virgin iron ore, which has fewer impurities. The internal production of scrap substitutes as the primary metallic feedstock provides integrated mini-mills with a competitive advantage over traditional scrap-based mini-mills by insulating the integrated mini-mills from their dependence on scrap,

which continues to be subject to price volatility. The internal production of metallic feedstock also enables integrated minimills to reduce handling and transportation costs. The high percentage use of scrap substitutes such as DRI also allows the integrated mini-mills to take advantage of periods of low scrap prices by procuring a wide variety of lower-cost scrap grades, which can be blended with the higher-purity DRI charge. Integrated mini-mills are substantially dependent upon iron ore which has been characterized by price volatility in recent years (as described for integrated steel production above). In addition, because the production of direct reduced iron involves the use of significant amounts of natural gas, integrated mini-mills are more sensitive to the price of natural gas also than are mini-mills using scrap.

Key steel products

Steel-makers primarily produce two types of steel products: flat products and long products. Flat products, such as sheet or plate, are produced from slabs. Long products, such as bars, rods and structural shapes, are rolled from blooms and/ or billets.

Flat products

Slab. A slab is a semi-finished steel product obtained by the continuous casting of steel or rolling ingots on a rolling mill and cutting them into various lengths. A slab has a rectangular cross-section and is used as a starting material in the production process of other flat products (e.g., hot-rolled sheet, plates). Slabs are typically between 200 millimeters and 250 millimeters thick.

Hot-rolled sheet. Hot-rolled sheet is minimally processed steel that is used in the manufacture of various non-surface critical applications, such as automobile suspension arms, frames, wheels, and other unexposed parts in auto and truck bodies, agricultural equipment, construction products, machinery, tubing, pipe and guard rails. All flat-rolled steel sheet is initially hot-rolled, a process that consists of passing a cast slab through a multi-stand rolling mill to reduce its thickness to typically between 2 millimeters and 25 millimeters, depending on the final product. Flat-rolled steel sheet that has been wound is referred to as "coiled". Alternatively, hot-rolled sheet can be produced using the thin slab casting and rolling process, where the hot-rolled sheet thickness produced can be less than one millimeter. This process is generally used in a flat products mini-mill, but some integrated examples exist as well.

Cold-rolled sheet. Cold-rolled sheet is hot-rolled sheet that has been further processed through a pickle line, which is an acid bath that removes scaling from steel's surface, and then successively passed through a rolling mill without reheating until the desired gauge, or thickness, and other physical properties have been achieved. Cold-rolling reduces gauge and hardens the steel and, when further processed through an annealing furnace and a temper mill, improves uniformity, ductility and formability. Cold-rolling can also impart various surface finishes and textures. Cold-rolled steel is used in

applications that demand higher surface quality or finish, such as exposed automobile and appliance panels. As a result, the prices of cold-rolled sheet are higher than the prices of hotrolled sheet. Typically, cold-rolled sheet is coated or painted prior to sale to an end-user.

Coated sheet. Coated sheet is generally cold-rolled steel that has been coated with zinc, aluminum or a combination thereof to render it corrosion-resistant and to improve its paintability. Hot-dipped galvanized, electro-galvanized and aluminized products are types of coated sheet and in recent times hot dipped coatings composed of zinc, magnesium and aluminum have grown in popularity. These are also the highest valueadded sheet products because they require the greatest degree of processing and tend to have the strictest quality requirements. Coated sheet is used for many applications, often where exposed to the elements, such as automobile exteriors, major household appliances, roofing and siding, heating and air conditioning equipment, air ducts and switch boxes, external structural applications as well as in certain packaging applications, such as food containers.

Plates. Plates are produced by hot-rolling either reheated slabs or ingots. The principal end uses for plates include various structural products such as for bridge construction, storage vessels, tanks, shipbuilding, line pipe, industrial machinery and equipment.

Tinplate. Tinplate is a light-gauge, cold-rolled, low-carbon steel usually coated with a micro-thin layer of tin. Tinplate is usually between 0.14 millimeters and 0.84 millimeters thick and offers particular advantages for packaging, such as strength, workability, corrosion resistance, weldability and ease in decoration. Food and general line steel containers are made from tinplate.

Electrical steels. There are two principal types of electrical steel: non-grain oriented fully processed steels and non-grain oriented semi-processed steels. Non-grain oriented fully processed steels are iron-silicon alloys with varying silicon contents and have similar magnetic properties in all directions in the plane of the sheet. They are principally used for motors, generators, alternators, ballasts, small transformers and a variety of other electromagnetic applications. A wide range of products, including a newly developed thin gauge material for high frequency applications, are available. Non-grain oriented semi-processed steels are largely non-silicon alloys sold in the not finally annealed condition to enhance punchability. Low power loss and good permeability properties are developed after final annealing of the laminations.

Long products

Billets/Blooms. Billets and blooms are semi-finished steel products. Billets generally have square cross-sections up to 180 millimeters by 180 millimeters, and blooms generally have square or rectangular cross-sections greater than 180 millimeters by 180 millimeters. These products are either continuously cast or rolled from ingots and are used for further processing by rolling to produce finished products like bars, wire rod and sections.

Bars. Bars are long steel products that are rolled from billets. Merchant bar and reinforcing bar (rebar) are two common categories of bars. Merchant bars include rounds, flats, angles, squares, and channels that are used by fabricators to manufacture a wide variety of products such as furniture, stair railings, and farm equipment. Rebar is used to strengthen concrete in highways, bridges and buildings.

Special bar quality ("SBQ") steel. SBQ steel is the highest quality steel long product and is typically used in safety-critical applications by manufacturers of engineered products. SBQ steel must meet specific applications' needs for strength, toughness, fatigue life and other engineering parameters. SBQ steel is the only bar product that typically requires customer qualification and is generally sold under contract to long-term customers. End-markets are principally the automotive, heavy truck and agricultural sectors, and products made with SBQ steel include axles, crankshafts, transmission gears, bearings and seamless tubes.

Wire rods. Wire rod is ring-shaped coiled steel with diameters ranging from 5.5 to 42 millimeters. Wire rod is used in the automotive, construction, welding and engineering sectors.

Wire products. Wire products include a broad range of products produced by cold reducing wire rod through a series of dies to improve surface finish, dimensional accuracy and physical properties. Wire products are used in a variety of applications such as fasteners, springs, concrete wire, electrical conductors and structural cables.

Structural sections. Structural sections or shapes are the general terms for rolled flanged shapes with at least one dimension of their cross-section of 80 millimeters or greater. They are produced in a rolling mill from reheated blooms or billets. Structural sections include wide-flange beams, bearing piles, channels, angles and tees. They are used mainly in the construction industry and in many other structural applications.

Rails. Rails are hot-rolled from a reheated bloom. They are used mainly for railway rails but they also have many industrial applications, including rails for construction cranes.

Seamless tubes. Seamless tubes have outer dimensions of approximately 25 millimeters to 508 millimeters. They are produced by piercing solid steel cylinders in a forging operation in which the metal is worked from both the inside and outside. The final product is a tube with uniform properties from the surface through the wall and from one end to the other.

Steel sheet piles. Steel sheet piles are hot rolled products used in civil engineering for permanent and temporary retaining structures. Main applications are the construction of quay walls, jetties, breakwaters, locks and dams, river reinforcements and channel embankments, as well as bridge

abutments and underpasses. Temporary structures like river cofferdams are made with steel sheet piles. A special combination of H beams and steel sheet piles are sometimes used for the construction of large container terminals and similar port structures.

Welded pipes and tubes. Welded pipes and tubes are manufactured from steel sheet that is bent into a cylinder and welded either longitudinally or helically.

Mining products

ArcelorMittal's mining products correspond to iron ore which is also one of the main raw materials for steel operations.

ArcelorMittal's mining and raw materials supply strategy consists of:

• Acquiring and expanding production of raw materials, in particular iron ore but as well some other specific products crucial to the Company's steel operations such as refractory and lime (in partnership with companies who are leaders in these domains), while keeping the cost under control;
• Exploiting its global purchasing reach, pursuing the lowest unit price available based on the principles of total cost of ownership and value-in-use through aggregated purchasing, supply chain and consumption optimization; and
• Leveraging local and low cost advantages on a global scale.

ArcelorMittal's priority is to optimize output and production from its existing sources focused mainly on iron ore.

ArcelorMittal believes that its portfolio of mining assets and long-term supply contracts (see below "—Raw materials and energy") can play an important role in preventing disruptions in the production process. (see "Operating and financial review— Key factors affecting results of operations—Raw materials").

ArcelorMittal sources significant portions of its iron ore needs from its own mines in Ukraine, Bosnia, Canada, Mexico, Liberia and Brazil. Several of ArcelorMittal's steel plants also have in place off-take arrangements with suppliers located near its production facilities.

For further information on Mining segment iron ore production, see "Operating and financial review—Operating results". For further information on each of ArcelorMittal's principal iron ore mining operations including total mining production of iron ore and coal, see "Properties and capital expenditures—Property, plant and equipment" and "Properties and capital expenditures —Property, plant and equipment— Mineral reserves and resources".

Raw materials and energy

Iron ore

ArcelorMittal is a party to contracts with other mining companies that provide long-term, stable sources of raw materials. The Company extended its multi-year iron ore supply contracts with Vale in 2024 to cover its requirements for the EU units, worldwide direct reduction units and for its Tubarão steel mill (ArcelorMittal Pecém, ArcelorMittal Brasil, being covered by a specific long-term agreement). ArcelorMittal's principal international iron ore suppliers include Vale in Brazil, Luossavaara-Kirunavaara AB in Sweden, Baffinland Iron Mines Corporation ("BIM") in Canada, IOC (Rio Tinto Ltd.) in Canada, Samarco in Brazil, Anglo-American (Minas Rio in Brazil), and Metinvest in Ukraine.

Coal

ArcelorMittal's principal coal suppliers include the BHP Billiton Mitsubishi Alliance ("BMA"), Anglo Coal, Peabody, Glencore in Australia, Contura and Warrior in the United States, Teck Coal in Canada, and JSW in Poland.

Metallics (scrap)

ArcelorMittal procures the majority of its scrap requirements locally and regionally, optimizing transport costs. Typically, scrap purchases are made in the spot market on a monthly/ weekly basis or with short-term contracts.

Alloys

ArcelorMittal purchases its requirements of bulk and noble alloys from a number of global, regional and local suppliers on contracts that are linked to generally-accepted indices or negotiated on a quarterly basis.

Base metals

The majority of the Company's base metal needs, including zinc, tin, aluminum and nickel are purchased under annual volume contracts. Pricing is based on the market-accepted indices. Material is sourced from both local and global producers.

Electricity

ArcelorMittal generally procures its electricity through tariffbased systems in regulated areas such as parts of the United States and South Africa, through direct access to markets in most of its European mills or through bilateral contracts elsewhere. The duration of these contracts varies significantly depending on the area and type of arrangement.

For integrated steel mills, plant off-gases from various process steps are utilized to generate a significant portion of the plant's electricity requirements and lower the purchase volumes from the grid. This is either produced by the plant itself or with a partner in the form of a co-generation contract.

Natural gas

ArcelorMittal procures much of its natural gas requirements for its Canadian and Mexican operations from the natural gas spot market or through short-term contracts entered into with local suppliers, with prices fixed either by contract or tariffbased spot market prices. For its European and Ukrainian operations, with a contractual mix of "all-in" bilateral supply and direct access to the market, ArcelorMittal sources its natural gas requirements with European short term/spotindexed supply contracts. The remainder of ArcelorMittal's natural gas consumption is generally sourced from regulated markets.

Industrial gases

Most of ArcelorMittal's industrial gas requirements are produced and supplied under long-term contracts with various suppliers in different geographical regions.

Coke

ArcelorMittal has its own coke-making facilities at most of its integrated mill sites, including in Canada, Brazil, Spain, France, Germany, Belgium, Poland, South Africa, and Ukraine. While ArcelorMittal meets most of its own coke requirements, certain of ArcelorMittal's operating subsidiaries purchase coke mainly from seaborn market from China, U.S, Japan, Australia, Colombia, and Indonesia and certain of its subsidiaries occasionally also sell excess coke at market prices to third parties.

Shipping

ArcelorMittal Shipping ("AM Shipping") provides ocean transportation solutions to ArcelorMittal's manufacturing subsidiaries and affiliates. AM Shipping determines costefficient and timely approaches for the transport of raw materials, such as iron ore, coal, coke and scrap, and semifinished and finished products. AM Shipping is also responsible for providing shipping services to the Company's sales organizations. It provides complete logistics solutions from plants to customer locations using various modes of transport.

In 2024, AM Shipping arranged transportation for approximately 54.1 million tonnes of raw materials and about 7.2 million tonnes of finished products. The key objectives of AM Shipping are to ensure cost-effective and timely shipping services to all units. AM Shipping also acts as the coordinator for Global Chartering Ltd., the Company's joint venture with DryLog Ltd., a Monaco based shipping company.

Purchasing

ArcelorMittal has implemented a global procurement process for its major procurement requirements, including raw materials, capital expenditure items, energy and shipping. ArcelorMittal's centralized procurement teams also provide services such as optimization of contracts and the supply base, logistics and optimizing different qualities of materials suitable for different plants and low cost sourcing.

By engaging in these processes, ArcelorMittal seeks to benefit from economies of scale in a number of ways, including by establishing long-term relationships with suppliers that sometimes allow for advantageous input pricing, pooling its knowledge of the market fundamentals and drivers for inputs and deploying specialized technical knowledge. This enables ArcelorMittal to achieve a balanced supply portfolio in terms of diversification of sourcing risk in conjunction with the ability to benefit from a number of its own raw materials sources.

ArcelorMittal has institutionalized the "total cost of ownership" methodology as its way of conducting its procurement activities across the Group. This methodology focuses on the total cost of ownership for decision making, with the goal of lowering the total cost of production through minimization of waste, improved input material recovery rates and higher rates of recycling.

Sustainability principles are embedded into ArcelorMittal general procurement conditions, purchasing contracts, in the onboarding process and supplier performance management in the area of safety, health, environment, human rights, and employee relations.

Sales and marketing

In 2024, ArcelorMittal sold 54.3 million tonnes of steel products.

Sales

The majority of steel sales from ArcelorMittal are destined for domestic markets. For these domestic markets, sales are usually approached as a decentralized activity that is managed either at the business unit or at the production unit level. For certain specific markets, such as automotive, there is a global approach offering similar products manufactured in different production units around the world. In instances where production facilities are in relatively close proximity to one another, and where the market requirements are similar, the sales function is aggregated to serve a number of production units. In the EU and in South America, ArcelorMittal owns a large number of service and distribution centers. Depending on the level of complexity of the product, or the level of service required by the customer, the service center operations form an integral part of the supply chain to ArcelorMittal's customers. Distribution centers provide access to ArcelorMittal's products to smaller customers that cannot or do not want to buy directly from the operating facility.

The Group prefers to sell exports through its international network of sales agencies to ensure that all ArcelorMittal products are presented to the market in a cost-efficient and coordinated manner.

Sales are executed at the local level, but are conducted in accordance with the Group's sales and marketing and code of conduct policies.

For some global industries with customers in more than one of the geographical areas that ArcelorMittal serves, the Company has established customized sales and service functions. This is particularly the case for the automotive industry. Sales through this channel are coordinated at the Group level with respect to contract, price and payment conditions.

Marketing

Marketing follows the sales activity very closely and is by preference executed at the local level. In practice, this leads to a focus on regional marketing competencies, particularly where there are similarities among regional markets in close geographical proximity. Local marketing provides guidance to sales on forecasting and pricing. At the global level, the objective is to share marketing intelligence with a view towards identifying new opportunities, either in new products or applications, new product requirements or new geographical demand. Where a new product application is involved, the in-house research and development unit of ArcelorMittal is involved in developing the appropriate products.

An important part of the marketing function at ArcelorMittal is to develop short-range outlooks that provide future perspectives on the state of market demand and supply. These outlooks are shared with the sales team in the process of finalizing the sales strategy for the immediate future and with senior management when market conditions call for production adjustments.

Globally, sales and marketing activities are coordinated to ensure a harmonized approach to the market. The objective is to provide similar service experiences to all customers of ArcelorMittal in each market.

Intellectual property

ArcelorMittal owns and maintains a patent portfolio covering processes and steel products, including uses and applications that it creates, develops and implements in territories throughout the world. Such patents and inventions primarily relate to steel solutions with new or enhanced properties, as well as new technologies that generate greater costefficiencies.

ArcelorMittal also owns trademarks, both registered and unregistered, relating to the names and logos of its companies and the brands of its products. ArcelorMittal has policies and systems in place to monitor and protect the confidentiality of its know-how and proprietary information. The Company applies a general policy for patenting selected new inventions, and its committees organize an annual patent portfolio screening by individuals from the Company's R&D and business sectors in order to optimize the global efficiency of the Company's patent portfolio. The Company's patent portfolio includes more than 14,000 patents and patent applications, mostly recent and medium-term, for more than 930 patent families, with 110 inventions newly-protected in 2024. Because of this constant innovation, the Company does not expect the lapse of patents that protect older technology to materially affect medium term revenue.

In addition to its patent portfolio, ArcelorMittal is constantly developing technical know-how and other unpatented proprietary information related to design, production process, decarbonization solutions for steel production and use of high quality steel products, leading to development of new applications or to improvement of steel solutions proposed to its customers, such as the ones aiming at weight reduction for vehicles. ArcelorMittal has also been granted licenses for technologies developed by third parties in order to allow it to propose comprehensive steel solutions to customers. ArcelorMittal is not aware of any pending lawsuits alleging infringement of others' intellectual property rights that could materially harm its business.

Government regulations

ArcelorMittal's operations are subject to various regulatory regimes in the regions in which it conducts its operations. The following is an overview of the principal features of the Company's regulatory regimes, as of December 31, 2024, that affect or are likely to significantly affect the Company's operations.

See also "Introduction—Risk factors and Control", "Sustainable Development—Health and Safety" and note 9.3 to ArcelorMittal's consolidated financial statements.

Environmental laws and regulations

ArcelorMittal's operations are subject to a broad range of laws, directives and regulations relating to air emissions, surface and groundwater protection, wastewater storage, treatment and discharges, the use and handling of hazardous or toxic materials, waste management, recycling, treatment and disposal practices, the remediation of environmental contamination, the protection of soil, biodiversity and ecosystems or rehabilitation (including in mining).

As environmental laws and regulations in the European Union ("EU") stemming from the Green Deal and other jurisdictions continue to become more stringent, ArcelorMittal expects to spend substantial resources, including operating and capital expenditures, to achieve or maintain ongoing compliance. Further details regarding specific environmental proceedings involving ArcelorMittal, including provisions to cover environmental remedial activities and liabilities, decommissioning and asset retirement obligations are described in note 9.1 to ArcelorMittal's consolidated financial statements.

Globally, the regulatory backdrop to environmental compliance in industry is developing rapidly and becoming more stringent, notably through the roll-out of the CSRD reporting and preparation for Task Force on Nature-related Financial Disclosure ("TNFD"). Environmental impacts such as that of air emissions are coming under greater scrutiny as evidenced by the updated air quality guidelines issued by the World Health Organization ("WHO") in September 2021. These guidelines have contributed to the recent adoption of the Air Quality Directive (Directive (EU) 2024/2881), alongside the updated Best Available Techniques Reference Document ("BREF") for the Ferrous Metals Processing Industry, among others. These changes will result in stricter environmental norms concerning pollution (emissions to air, water and land), broader impacts on natural environments, habitats and biodiversity, and energy efficiency and resource efficiency, as well as promoting more sustainable industrial production (part of the European Commission's Green Deal for a climateneutral continent) and increased transparency of information available to public.

European Union

The revised Industrial Emission Directive (Directive 2024/1785 or "IED 2.0") entered into force in August 2024. The overall aim of the IED 2.0 is to minimize the impact of pollution on people's health and the environment by reducing harmful industrial and intensive livestock emissions across the EU. The IED 2.0 imposes stricter rules for defining emission limit values and in respect of permit requirements as well as tighter

compliance and control rules with additional enforcement provisions. The operators of industrial installations will need to develop transformation plans to achieve the EU's 2050 zero pollution, circular economy, and decarbonization goals. The revised directive focuses on resource use performance levels, as well as lower chemical pollution through requirements for a reduced use of toxic chemicals. Furthermore, the new EU Industrial Emissions Portal Regulation (EU) 2024/1244 which replaces the European Pollutant Release and Transfer Register Regulation (E-PRTR) entered into force in May 2024. This revision enhances public access to information related to industrial emissions. During the next two years, the European Commission will work on implementing rules, with the first report under the revised directive (describing releases and resource use in 2027) scheduled for publication in 2028.

In the context of supply chain, the German Supply Chain Due Diligence Act 2022 ("Lieferkettensorgfaltspflichtengesetz"), which came into force in January 2023, provides a legal framework for fulfilling human rights due diligence obligations and requires that German companies undertake due diligence in their supply chains and motivate their contract partners abroad to protect internationally recognized human rights and environmental standards.

Additionally, in July 2024, the Directive on Corporate Sustainability Due Diligence Directive ("Directive 2024/1760") (CS3D) entered into force, establishing a corporate due diligence duty, including to identify and address potential and actual adverse human rights and environmental impacts in the company's own operations, the operations of its subsidiaries and, where related to their value chain(s), those of its and their business partners. In addition, Directive 2024/1760 sets out an obligation for large companies to adopt and put into effect, through best efforts, a transition plan for climate change mitigation aligned with the 2050 climate neutrality objective of the Paris Agreement as well as intermediate targets under the European Climate Law.

ArcelorMittal has established and updated policies in response to these requirements. It aims to assess risks by identifying them with regards to negative impacts on human rights within the Company's value chain; to deal with negative impacts by taking preventive measures to minimize and remedy potential impacts; to follow up on the progress of these measures; to communicate the results to its stakeholders; and to set up complaint mechanisms.

In December 2015, 195 countries participating in the United Nations Framework Convention on Climate Change ("UNFCC"), at its COP21 held in Paris, adopted a global agreement on the reduction of climate change (the "Paris Agreement"). The Paris Agreement sets a goal to limit the increase in the global average temperature to well below 2 degrees Celsius and pursues efforts to limit the increase to 1.5 degree Celsius, to be achieved by getting global GHG emissions to peak as soon as possible. The Paris Agreement consists of two elements: first, a legally binding commitment

by each participating country to set an emissions reduction target, referred to as nationally determined contributions ("NDCs"), with a review of the NDCs that could lead to updates and enhancements every five years beginning in 2023 (Article 4), and second, a transparency commitment requiring participating countries to disclose in full their progress (Article 13). Most countries have issued their intended NDCs.

The United Nations Climate Change Conference COP 28 reached a deal for transitioning away from fossil fuels in energy systems, in a just, orderly, and equitable manner, as well as on tripling renewable energy capacity globally by 2030, speeding up efforts to reduce coal use, and accelerating technologies such as CCUS that can decrease emissions of hard-to-abate industries. By 2025, countries must present their updated NDCs aimed at being aligned with the 1.5 degree Celsius limit. At COP 29, a new collective quantified goal on climate finance destined towards developing countries was reached, and the rules for the operationalization of Article 6 of the Paris Agreement, which provides for bilateral and global carbon trading were finalized.

On July 14, 2021, the European Commission adopted the Fit for 55 Package with a view to adapting climate and energy legislation to the 2030 ambition set by the European Climate Law. The EU also committed internationally to its 55% reduction target. Most of the initiatives of the Fit for 55 Package have been adopted as of December 31, 2024, amending several pieces of legislation that were already applicable to ArcelorMittal, such as the EU-ETS, the Renewable Energy Directive ("RED") and the Energy Efficiency Directive ("EED") as well as introducing the CBAM. CBAM is a tool to put an equivalent price to that faced by domestic production on the carbon emitted during the production of certain goods that are imported into the EU. The CBAM established a transition period of October 1,2023 to December 31, 2025, during which there will be no financial obligation besides the possibility of penalties being imposed for failures to report. There are some implementation rules stemming from the ETS and CBAM that are still currently under preparation. In addition, the Energy Taxation Directive ("ETD") is expected to be revised in 2025. ArcelorMittal's activities in the 27 member states of the EU are subject to the EU-ETS, which was launched in 2005 pursuant to European Directive 2003/87/EC, relating to GHG emissions. The EU-ETS is based on a cap-and-trade principle, setting a cap on GHG emissions from covered installations that is then reduced over time. Within this cap, companies receive emission allowances which they can sell to or buy from one another as needed. The limit on the total number of allowances available ensures that they have a value. In order to achieve the EU 2030 55% reduction ambition, the ETS requires sectors under ETS to reduce their emissions by 62%. As required by the EU Climate Law, the Commission has begun to define a Europewide 2040 target. In February 2024, the Commission presented its assessment for a 2040 climate target for the EU,

recommending reducing the EU's net GHG emissions by 90% by 2040 relative to 1990. The legislative proposal to amend the EU Climate Law with a 2040 target is expected in the first quarter of 2025. The review of the ETS will follow to reflect the adopted 2040 target.

The implementation rules for the second trading period of Phase IV (2026-2030) will further reduce current benchmark values, although the adopted approach will prevent a large disruptive decrease of the hot metal benchmark. Still, the resulting shortage in free allocation levels would put the European steel industry at a significant disadvantage versus global competition (see note 9.1 to the consolidated financial statements). To prevent such disadvantages, CBAM has been established for a limited number of sectors, including steel, with a transitional period that started in October 2023 and runs until the end of December 2025, with the initiation of CBAM payments in 2026. In the case of the steel sector, only direct emissions will be covered, at least through 2025, allowing access to indirect cost compensation. On the other hand, free allocation to covered sectors will be progressively phased out as follows: 2026: 97.5%, 2027: 95%, 2028: 90%, 2029: 77.5%, 2030: 51.5%, 2031: 39%, 2032: 26.5%, 2033: 14%, and 0% as from 2034. The agreement does not include a solution for exports but requires the European Commission to prepare an assessment and report by 2025. Several implementing acts to supplement the CBAM regulation are still to be developed.

Moreover, the revised Renewable Energy Directive ("RED") was adopted in November 2023, increasing the current EUlevel target of at least 32% of renewable energy sources in the overall energy mix to at least 42.5% by 2030. Member States must also collectively endeavor to increase the share of energy from renewable sources in the EU's gross final consumption of energy in 2030 to 45%. The RED aims to deploy renewables across all sectors, particularly in sectors where progress in integrating renewables had been slower.

Additionally, the revised Energy Efficiency Directive ("EED") raised the EU energy efficiency target, making it binding for EU countries to collectively ensure an additional 11.3% reduction in energy consumption by 2030 compared to the 2020 reference scenario projections. In addition, the revised Land Use, Land Use Change and Forestry ("LULUCF") sets a target for net GHG removals at 310 million tonnes of CO² equivalent as a sum of the values of the GHG net emissions and removals by Member States in 2030. The LULUCF sector is connected to all ecosystems and economic activities that rely on the land and the services it provides, thus directly impacting ArcelorMittal's sites.

Furthermore, the Eco-design for Sustainable Product Regulation ("ESPR") is a cornerstone in the European Green Deal for more environmentally sustainable and circular products. The new regulation acts as a framework and complements existing product regulation. The regulation is implemented following a workplan through secondary legislation by Delegated Acts. As part of the new Commission work plan, the Joint Research Centre ("JRC") is expected to finalize a preparatory study on Iron and Steel Products by June 2025. The ESPR framework will make "Digital Product Passports" mandatory and must ensure that relevant environmental information is transferred along the supply chain on a need-to-know basis.

Environmental requirements impacting industrial operations are also becoming more stringent in various jurisdictions.

Argentina

Argentina's goal is to achieve carbon neutrality by 2050, and it has outlined its NDCs compromises for 2030, reinforcing them through participation in COP 28. During 2023, the Argentinian government established two key strategies: one for the Carbon Trade Market (Resolution N° 385/2023) and another for Hydrogen Economy Development. The program was launched in 2023 with the participation of more than 120 participants, and the roadmap for the industrialization of hydrogen as a productive vector in the energy transition was presented.

Additionally, the Renewable Energy Law has set mandatory national targets for electricity consumption from renewable energy sources: 8% in 2018; 12% in 2019/20; 16% in 2021/22; 18% in 2023/24; and 20% in 2025. All energy-intensive industries must contribute to these mandatory national targets, but no significant impact on the Company is expected. Acindar has outlined its renewable energy business plan as follows: (i) for the Villa Constitución Site, targets are being met by purchasing renewable energy from Cammesa.

Brazil

In Brazil, new federal laws have been established in 2024 to guide climate change adaptation plans and create a legal framework for low-carbon hydrogen, including incentives and programs for its production and development. The states of Minas Gerais, Ceará and Santa Catarina have also introduced their own green hydrogen policies. Additionally, federal laws have launched programs to promote sustainable low-carbon mobility, including green mobility, sustainable aviation fuel, green diesel, and biomethane. A national air quality policy has been established, setting standards and guidelines for air quality management. Forestry has been excluded from the list of potentially polluting activities, and environmental licensing for forestry has been simplified in Minas Gerais. Furthermore, federal decrees have set guidelines for the national circular economy strategy and regulated tax incentives for the recycling production chain. In São Paulo, a state decree has established a program to manage solid urban waste. Specific impacts are yet to be regulated.

The state of Minas Gerais (where the Serra Azul Dam is located) published State Decree No. 48.848/2024, which included new types of guarantees, such as mortgages and fiduciary alienation of real estate. The validity of bank guarantees has been extended to a minimum of five years, with financial institutions required to deposit the guaranteed

credit within 15 days if the debtor fails to renew the bond. Additionally, the insurance policy must be issued by a Susepauthorized insurance company, with the credit settlement period extended to 30 days after notification. The deadline for presenting environmental bonds for dams has been increased from 180 to 270 days. Furthermore, the real estate offered as a guarantee can be re-evaluated at any time and must be supplemented if its value is lower than declared. These changes aim to enhance security and flexibility in managing environmental guarantees.

In 2022, Brazil launched Resolution No. 433/2021 establishing the National Policy of the Judiciary for the Environment, establishing the monitoring of climate actions and mandating that indemnities for environmental damages include the impact on global climate change, as well as diffuse damage to affected peoples and communities. In September 2023, the Plenary of the Brazilian National Council of Justice approved a Normative Act recommending the adoption of a new protocol for the trial of environmental damage actions by Brazilian courts. This aims to enhance the effectiveness of judgments in environmental cases, providing guidelines on the use of evidence obtained by sensors and satellites. The focus is on preventing and combating environmental externalities, particularly concerning climate change and collective damage.

Brazil has established the Interministerial Committee on Climate Change ("CIM") through Decree No. 11.550/2023, published in June 2023, which monitors the implementation of actions and public policies within the federal executive branch related to the National Policy on Climate Change ("PNMC"). The decree revoked the former National System for the Reduction of Emissions of Greenhouse Gases ("SINARE"), previously established by Decree No. 11.075/2022.

Law No. 15.042/2024, which regulates the carbon market in Brazil creating the Brazilian Greenhouse Gas Emission Trading System was approved in December 2024. The new law is based on a minimum emissions threshold rather than specific sectors. Installations emitting above 10 thousand tonnes of CO2 per year per source or installation must report their emissions. Installations emitting more than 25 thousand tonnes of CO2 per year, in addition to mandatory reporting, must carry out periodic reconciliation of obligations. The regulation applies equally to all sectors of the economy, except for primary agricultural production which was expressly excluded.

The state of Ceará has published Law No. 18.458/2023, instituting the state policy for green, sustainable hydrogen and its derivatives within the scope of the state of Ceará and creating the state council for governance and development of the production of green, sustainable hydrogen and its derivatives.

Canada

In Canada, depollution attestations applicable to AMMC facilities are currently being renewed and may include more restrictive standards.

In the province of Quebec, the renewal requests for depollution attestations for AMMC's Mont Wright operations, Fire Lake, and Port-Cartier pellet plant are currently in the analysis stage by environmental authorities. They aim to apply the same standards to all mines. These permits establish targets for water, air, soil, and waste management, as well as the monitoring and reporting frequencies and requirements for each target.

Furthermore, the Contrecoeur West depollution attestation was scheduled to be renewed in 2023; the renewal application was filed in June 2023, awaiting further input from the Government. The Contrecoeur East depollution attestation is scheduled to be renewed in 2026, the application must be filled in the third quarter of 2025. Also, starting January 1, 2024, royalty rates are payable for contaminated soils for landfilling (CAD\$10/t) or treating (CAD\$5/t).

Quebec's government expanded the scope of the regulation related to compensation for adverse effects on wetlands and bodies of water. It will apply to projects conducted in Port-Cartier, Mont Wright, and Fire Lake and might extend to AMLPC's future projects. Also in Quebec, the regulation respecting royalties payable for the use of water was amended to increase, as of January 1, 2024, the royalty rates from CAD\$2.5 per million liters ("CAD\$/ML") of water to CAD\$35/ML, and from CAD\$70/ML to CAD\$ 150/ML. The applicable rate will vary according to the use of the resource. These rates are subject to indexation every year by 3% per annum.

The ECCC, the Iron Ore Company of Canada, and AMMC have entered into an environmental performance agreement effective from January 5, 2018 until June 1, 2026. The agreement is designed to facilitate the implementation of BLIERs developed for the iron ore pellet sector. Specifically, it outlines the composition, timelines, and objectives of the NOx Working Group. The agreement aims to ensure compliance with BLIERs limits for Particulate Matter ("PM") 2.5 and SO2 while also overseeing the implementation of the approach to studying NOx.

At the national level, the Environment and Climate Change Canada ("ECCC"), a department of the Government of Canada, updated the Base-Level Industrial Emissions Requirements ("BLIERs") under the federal Air Quality Management System, resulting in the need for substantial investments to comply with emission regulations. Provincial regulations in Ontario and Quebec will also require additional emissions reductions.

In Ontario, the BLIER requires all coke plants in the province to install coke oven gas desulphurization in order to meet SO2 limits by the end of December 2025. In 2023, ArcelorMittal

Dofasco received an exemption from the ECCC due to its ongoing decarbonization efforts. Currently, on a plant-wide basis, ArcelorMittal Dofasco's facility is meeting its BLIERs objective. Moreover, the decarbonization project will impact ArcelorMittal Dofasco's overall Nitrogen Oxide ("NOx") emissions.

In Canada, carbon pricing regulations have become increasingly stringent. For example, the Order Amending Schedule 3 to the GHG Pollution Pricing Act: Statutory Orders and Regulation ("SOR")/2022-210 introduces amendments to set the royalty amounts per tonne of GHG emitted for the years 2023 to 2030.

As from January 1, 2022, ArcelorMittal Dofasco and Ontario industries have been regulated on carbon pricing under the Ontario Emissions Performance Standards ("EPS"), transitioning out of the Federal output-based pricing system ("OBPS"). The Federal government intends to ensure provincial GHG programs are rigorous enough to meet Federal carbon reduction targets (40 - 45% lower than in 2005 by 2030).

In March 2023, the Federal government updated the federal benchmark. Ontario subsequently published changes to the EPS carbon tax program for 2023 and 2030, which includes (i) changes to carbon pricing from CAD\$50/t CO2e to CAD\$65/t in 2023 and increasing CAD\$15/t annually up to CAD\$170/t CO2e by 2030, and (ii) changes to the stringency factors: -2.4% in 2023 and -1.5% annually from 2024 to 2030.

As part of the Ontario EPS program, the Ontario provincial authority signaled a recognition of the significant transformation in the steel sector for those large steel producers expected to make the transition to clean steel production in the coming years. In consideration of the changes at these facilities, stringency factors would be set equal to one for the transition period up to 2030; thus, exemptions will be considered for first movers in the steel sector. Final details have been provided and the Director's official issuance notice for the amendments were issued in the second quarter of 2024.

The development of an approach to address facility-specific emissions targets for the innovative DRI facilities has been completed, often based on three years of performance following the start-up of a facility. Detailed discussions concluded in 2023, and the final Director's order was issued in the first quarter of 2024. The proposed approach to address ArcelorMittal Dofasco's decarbonization program during the transformation periods has also been developed. Compliance of Director's order is to be achieved by reducing GHGs as well as additional first-mover considerations by the regulator.

In Quebec, the 2030 Plan for a Green Economy sets a 37.5% GHG emission reduction target by 2030 compared with 1990 levels, with the goal that Quebec reaches carbon neutrality by 2050. Separate consultations by the government of Quebec

are underway with large GHG emitters regarding the cap-andtrade program regulation for the second and subsequent compliance periods from 2021 to 2030. Quebec completed the consultations for the 2021 to 2023 compliance period. For the period 2024 to 2030, negotiations are still in progress to minimize the financial impact of regulatory changes on ArcelorMittal's operating subsidiaries in Canada.

As part of Canada's climate plan to reduce emissions and accelerate the use of clean technologies and fuels, in June 2022, the final Clean Fuel Regulations ("CFR") under the Canadian Environmental Protection Act 1999 ("CEPA") were registered, bringing the 2017 Clean Fuel Standard ("CFS") into law. It came into force upon registration, except for two sections repealing the pre-existing Renewable Fuels Regulations ("RFRs"), which will come into force on September 30, 2024. The CFS establishes lifecycle carbon intensity requirements separately for liquid, gaseous, and solid fuels that are used in transportation, industry, and buildings. This performance-based approach, intended to incentivize innovation, development, and use of a broad range of lowercarbon fuels, alternative energy sources, and technologies, only requires liquid fuel (e.g., gasoline, diesel, home heating oil) suppliers to reduce the carbon intensity of their fuels. Gaseous and solid fossil fuels have been eliminated from the scope. The Regulations will increase production costs for primary suppliers, which would increase prices for liquid fuel consumers.

Liberia

In Liberia, ArcelorMittal holds a mining concession, inclusive of 250 kilometers of rail and port facilities. The Environment Protection Agency ("EPA") in Liberia has heightened its enforcement of environmental standards, supported by its dedicated laboratories. The nearby presence of ArcelorMittal Liberia ("AML") installations has fueled local communities' environmental awareness, increasing pressure on AML from stakeholders.

Guided by the Environmental Protection Agency Act (2002) and the Environment Protection and Management Law (2002), comprehensive Environmental Impact Assessments ("EIAs") are mandatory for projects affecting the environment. In adherence to these regulations, ArcelorMittal has developed an Environmental and Social Standards Manual ("SSM"), approved by the Liberian EPA, governing all activities within the existing Liberia mining project. The SSM is regularly updated with external consultants' input, and the SSM surpasses local environmental requirements. ArcelorMittal's mining concession falls within the purview of the National Forestry Reform Law (2006), the National Forestry Law (2000), and the Act Creating the Forestry Development Authority (2000). These laws govern both commercial and community use of forests, and some territories within the concession are subject to these regulations. The Community Rights Law regarding Forest Lands (2009) has notably empowered communities in forest management. The stringent conditions attached to existing environmental permits reflect

the Company's dedication to sustainable operations; in connection with the Phase 2 project, ArcelorMittal has committed to an environmental offset program and mine closure plan, potentially exceeding \$100 million. In 2023, all environmental permits were renewed, covering Yuelliton mining activities, TSF construction, a new sewage plant, and the rehabilitation of rail and port facilities, has elevated requirements for sediment control, water discharge, and biodiversity conservation. In tandem, AML has initiated a climate change risk assessment and is participating in the TNFD studies. On October 17, 2024, the National Solid Waste Management Policy was published by the Environmental Protection Agency. The Policy outlines the vision of the Government of Liberia, which recognizes that effective and efficient waste management is essential for the development of sound public health and improved quality of life.

Mexico

In March 2022, Mexico published a new standard on wastewater discharges, reducing the maximum permissible limits and introducing new parameters for quarterly monitoring and reporting to the National Water Commission ("CONAGUA"). ArcelorMittal internally defined a preliminary action plan to enhance wastewater quality discharges in line with the requirement of the standard through operational controls. In April 2023, with prior authorization from CONAGUA, ArcelorMittal submitted an action plan outlining milestones to bring wastewater discharge in compliance with the new standard. This program is scheduled to conclude in February 2027, with progress reports required to update on the program's milestones.

Additionally, due to the recent reform of the National Mining Regulation ("NMR"), several significant changes have been made, mostly related to environmental, water and waste management. With respect to water, the changes primarily relate to water access by the population (in preference to industrial use of water), which may have an impact on the ability to use water for iron ore transportation. Several constitutional claims against the NMR were submitted (including claims by ArcelorMittal Mexico). The final rulings are expected to be resolved by the Supreme Court in 2025. As part of these ongoing trends in water management, ArcelorMittal Mexico joined the initiative of a National Agreement on Water and signed the agreement on November 14, 2024, voluntarily assigning 56.5% of its concessioned volume to the National Water Commission for 2025.

To fulfil its commitments under the Paris Agreement, the federal government of Mexico has published rules and principles for an emissions trading system (ETS) applicable to entities generating more than 100,000 tons of CO2 per year. Since 2020, a pilot of the ETS has been implemented by ArcelorMittal México Long and Flat Segments and Services areas ("SERSIINSA"), along with other relevant companies. This pilot stage is still in progress, with new rules potentially issued by the first quarter of 2025. During the pilot stage, ArcelorMittal México consistently adhered to the

environmental authority's ("SEMARNAT") emission calculation and reporting criteria for the ETS. ArcelorMittal's CO² emissions reports have consistently showed zero deficits. Despite the initial plan for the operational stage to start in 2023, In January 2024, SEMARNAT presented a proposal of the operating rules of the ETS with new growth factors and reduction factors for the mechanism to assign free emission allowances for all participants sectors. The authority has not officially defined operational stage rules, but an unofficial final proposal is expected soon.

In addition, since 2023, there has been a very marked trend by state governments in Mexico to implement green taxes on CO2 emissions, which caused an additional tax impact on different sectors that participate in other federal government schemes (e.g., ETS). Working groups have been formed within several trade associations and business chambers to promote initiatives that minimize the economic impacts on the industrial sector. Taxes range from \$2.2 - \$44.5 USD per ton of CO2 emitted.

South Africa

In South Africa, the proposed Phase 2 of the Carbon Tax discussion paper has been published by the National Treasury on November 13, 2024. The proposal as is poses a significant increase in carbon tax liability to ArcelorMittal South Africa with increase in annual carbon tax rates combined with a drastic phase down of tax-free allowances and stricter eligibility criteria to benefit from other tax-free allowances, all measures projecting a significant impact in financial terms to unaffordable levels. The proposal presented by National Treasury also includes a higher carbon tax of R640/tCO2e for emissions exceeding the allocated carbon budget to be applied to taxpayers as a penalty.

Also in South Africa, on April 26, 2024 the DFFE published the Draft Sectoral Emission Targets (SETs) Report for public comments. The report outlines institutional arrangements that will guide the SETs allocation to support the country's both national and international commitments to mitigate climate change.

Ukraine

In July 2024, Ukraine adopted the Law on "Integrated Prevention and Control of Industrial Pollution" (IPPC Law), which will enter into force on August 8, 2025. The document aims to prevent, reduce and control pollution arising from economic activities and applies an integrated approach to pollution regulation and implementation of best available technologies and management methods. According to the IPPC Law, all new entities are required to obtain an integrated permit after the law will enter into force. The existing entities have a transition period of four years to obtain integrated permits.

ArcelorMittal closely monitors local, national, and international negotiations, and regulatory and legislative developments, and endeavors to reduce its emissions where appropriate.

Foreign trade

ArcelorMittal has manufacturing operations in many countries and sells its products worldwide. In 2024, certain countries and regions, such as Canada, the EU, Mexico, Turkey and the U.S., continued or launched investigations into whether to impose or continue imposing trade remedies (usually antidumping or safeguard measures) against injury, or the threat thereof, caused by increasing steel imports originating from various steel producing countries.

Under both international agreements and the domestic trade laws of most countries, trade remedies are available to domestic industries where imports are "dumped" or "subsidized" and such imports cause injury, or a threat thereof, to a domestic industry. Although there are differences in how trade remedies are assessed, such laws have common features established in accordance with World Trade Organization ("WTO") standards. Dumping involves exporting a product at a price lower than that at which the same or similar product is sold in the home market of the exporter, or where the export prices are lower than a value that typically must be at or above the full cost of production (including sales and marketing costs) plus a reasonable amount for profit. Subsidies from governments (including, among others, grants and loans at artificially low interest rates) are similarly actionable under certain circumstances. The trade remedies available are typically (i) an anti-dumping duty order where injurious dumping is found and (ii) a countervailing duty order or suspension agreement where injurious subsidization is found. Normally, the duty is equal to the amount of dumping or subsidization that is generally imposed on the imported product (other than in the EU where the lesser duty rule is applied). Accordingly, such orders and suspension agreements do not prevent the importation of a product, but rather require that either the product be priced at a nondumped level or without the benefit of subsidies, or that the importer pays the difference between such dumped or subsidized price and the actual price to the government as a duty.

Safeguard measures are addressed more generally to a particular product, irrespective of its country of origin, to protect domestic production against serious injury caused by unforeseen, sharp and sudden increase of imports.

All WTO members are required to review anti-dumping duty and countervailing duty orders every five years to determine if they should be maintained, revised or revoked. This requires a review of whether the dumping or subsidization is likely to continue or recur if the order/suspension agreement is revoked and whether a domestic industry in the country is likely to suffer the continuation or recurrence of the injury within the reasonably foreseeable future if the orders are revoked. If the government finds dumping or subsidization and the injury is likely to continue or recur, then the orders continue. In the case of safeguard measures imposed for a period exceeding three years, all WTO members are required to conduct a mid-term review of the imposed measures. After

a review, safeguard measures may be extended if they continue to be required, but the total period for the application of safeguard measures may not exceed eight years.

In a number of markets in which ArcelorMittal has manufacturing operations, it may be the beneficiary of trade actions intended to address trade distortions consistent with WTO regulations, such as the examples mentioned above. In other situations, certain operations of ArcelorMittal may be a respondent to anti-dumping and countervailing duty cases and its exported products might be subject to anti-dumping and countervailing duties or other trade restrictions.

USA Section 232:

On March 23, 2018, after national security investigation with respect to steel imports (under Section 232 of the Trade Expansion Act ("Section 232")), the Trump Administration imposed tariffs of 25% on steel products from all but a select list of countries, with a temporary suspension applied for Canada, Mexico, Argentina, South Korea, Brazil and the EU until May 1, 2018. Subsequently, Australia obtained a full exemption, and imports from Argentina, Brazil and South Korea became subject to annual quotas. Tariffs on imports of steel products from Canada and Mexico were eliminated on May 17, 2019, which led to positive impacts in the Company's North America business units; imports from Canada and Mexico were monitored to identify whether imported volumes surged meaningfully beyond historical levels. Mexico's Section 232 tariff exemption was subsequently modified in July 2024 to apply only to Mexican steel products melted and poured in North America.

On October 31, 2021, the United States and EU announced that they had reached a two-year agreement to modify the Section 232 measures on U.S. steel imports from the EU, which was further extended for another two years in December 2023. Effective January 1, 2022, the U.S. replaced the existing Section 232 tariffs on EU steel with a tariff-rate quota ("TRQ") consistent with pre-Section 232 trade volumes in return for the EU dropping the threat of retaliatory tariffs. The total annual import volume under the TRQ is set at 3.3 million tonnes allocated by product category and on an EU member state basis. Only steel "melted and poured" in the EU is eligible for duty-free treatment. Imports above the TRQ volumes will continue to be subject to the 25% tariff. An additional 1.1 million tonnes of products previously excluded from Section 232 tariffs are also allowed to continue duty-free. Subsequently, the U.S. reached similar agreements with Japan and the UK, also replacing the 25% Section 232 tariffs with tariff-rate quotas. Those agreements took effect on April 1, 2022 (Japan) and June 1, 2022 (UK).

In May 2022, the U.S. suspended Section 232 tariffs on imports of steel from Ukraine. In May 2023, the suspension was extended for an additional year and expanded to include steel products from Ukraine further processed in the EU. In May 2024, the suspension and expansion were extended until June 1, 2025.

In February 2025, the U.S. administration announced that it would reinstate 25% tariffs on all steel and aluminum imports under Section 232, revoking previously negotiated countryspecific exemptions and quota arrangements from March 12, 2025 (including those described above).

The 2018 Section 232 tariffs triggered concerns of trade deflection worldwide and several countries initiated domestic remediation measures. On February 2, 2019, the EU Commission imposed definitive safeguard measures based on global tariff quotas with a 100% quota based on average imports over the past three years prior to 2018 and covering 26 steel product categories. Imports that exceeded the above quotas would face a 25% tariff but certain 'developing' countries were exempt when their respective import shares were below 3%. The measures set country-based quotas for larger importers on all product categories, except for hot rolled (global), and quarterly quota calculations for residual volumes of all products. They also included annual quota relaxations, adaptable to market conditions. Countries subject to quotas have an incentive to front-load the consumption of their national quota in order to benefit from the residual quotas in the final quarter of the period, thus ensuring full quota consumption.

In 2021, the EU Commission carried out a review resulting in a three-year extension prolonging the measures until June 30, 2024. It was agreed to carry out a review of the quota levels after one year and a review of the measures in general after two years. The first of these reviews took place in 2022 and a further review in 2023 confirmed the measures until June 2024. Following a further review in the first half of 2024, the measures were extended until June 30, 2026.

If the Section 232 tariffs are reinstated in full, the European Union and other countries may implement counter measures in response.

Separately, from April 1, 2022, all Russian and Belarusian quota volumes were redistributed across other countryspecific quotas and the residual quota based on 2021 imports.

In 2024, the Commission extended anti-dumping measures on corrosion-resistant steel from China for a further five years.

On April 30, 2024 an expiry review was opened by the Commission into existing anti-dumping and anti-subsidy measures on organic coated steel from China.

During 2024, the Commission also opened anti-dumping investigations into hot-rolled coil from Japan, India, Egypt and Vietnam, and tin plate from China. These investigations are ongoing.

In January 2021, Turkey opened an investigation into HRC coming from the EU and South Korea. The investigation led to a 10.9% duty being applied to imports from ArcelorMittal as from July 7, 2022. In 2023, Turkey opened a safeguard

investigation into Wire Rod imports, imposing provisional measures while the investigation is ongoing.

In 2022, the U.S. completed reviews of anti-dumping and countervailing duty measures in place on corrosion-resistant, cold-rolled, and hot-rolled steel, and cut-to-length steel plate, continuing most duties for another five years.

In January 2023, the U.S. initiated an anti-dumping investigation regarding tin mill products from eight countries, including Canada. ArcelorMittal Dofasco was named as a respondent in the case. In February 2024, a final decision confirmed that no measures will be imposed on any of the targeted eight countries.

In September 2024, the U.S. industry petitioned a new Corrosion-Resistant anti-dumping case against ten countries, and subsidy case against four countries. Canada and Mexico were included in both allegations. In October 2024, the United States International Trade Commission ("ITC") made a preliminary injury determination against all ten countries. The United States Department of Commerce ("DOC") and ITC final injury phases are expected to continue to the third quarter of 2025.

In September 2024, the U.S. modified its tariff action in the Section 301 investigation of China's unfair trade practices, increasing the section 301 tariffs on imports of Chinese steel from 7.5% to 25%. The section 301 tariff is in addition to applicable tariffs under Section 232 and existing anti-dumping and countervailing duties. Duties were also increased on a number of other products in strategic sectors, including electric vehicles (duty of 100%).

In Canada, as a result of the opening of a safeguard investigation on certain flat and long products, provisional measures were put in place on October 25, 2018 in the form of quotas and a 25% tariff on steel imports. Final safeguard measures were subsequently implemented in relation to plate and stainless wire, but not on rebar, hot rolled, prepaint, wire rod and energy tubulars. In addition, twelve cold-rolled and corrosion-resistant anti-dumping and countervailing duty measures were implemented between 2018-2020 (CRS, COR, COR2). In 2022, anti-dumping and countervailing duty measures were initiated for hot-rolled from China, Brazil, Ukraine and India under a five-year review (HRSS), while Ukraine was removed from the measures. In September 2024, six cold-rolled anti-dumping and subsidy measures (CRS) were continued for another five years, and in November 2024, Canada continued four corrosion-resistant anti-dumping measures (COR) for another four years. In December 2024, the Canadian Government self-initiated a new corrosionresistant anti-dumping measure (COR3) against Turkey (Borcelik), with final determination expected in July 2025.

For rebar, nineteen anti-dumping and countervailing duty measures were implemented between 2015 to 2021 (RB1- RB4), with ten measures continued in two separate five-year

reviews in 2020 (RB1) and 2022 (RB2). In May 2024, a new rebar anti-dumping case (RB5) was initiated against three countries and implemented in January 2025. Finally, a new wire rod anti-dumping case against three countries (WR) was initiated in March and implemented in October 2024.

In February 2024, the Canadian government announced implementation of a "Country of Melted and Poured" steel import monitoring system, with mandatory reporting effective November 2024.

In addition, to align with the U.S. 301 duties on Chinese unfair trade practices, the Canadian government implemented a Section 53 surtax of 100% on Chinese electric vehicles, effective October 1, 2024, and a 25% Section 53 surtax on Chinese steel and aluminum, effective October 22, 2024. These surtaxes are in addition to any duties or tariffs applicable to Chinese steel and aluminum.

Key currency regulations and exchange controls

As a holding company, ArcelorMittal is dependent on the industrial franchise fees from, earnings and cash flows of, and dividends and distributions from, its operating subsidiaries to pay expenses, meet its debt service obligations, pay any cash dividends or distributions on its ordinary shares or conduct share buy-backs. Significant cash or cash equivalent balances may be held from time to time at subsidiaries where repatriation of funds may be affected by tax and foreign exchange policies, including in Argentina, Brazil, China, South Africa and Ukraine. Such policies are briefly summarized below; however, none of these are currently significant in the context of ArcelorMittal's overall liquidity.

Argentina

The Argentinian foreign exchange market is regulated by the Argentine Central Bank ("BCRA"), which has introduced measures affecting the foreign exchange market since 2018 in an effort to improve macroeconomic conditions and bring stability to the country.

In December 2023, the government devalued the Argentine peso ("ARS") against the U.S. dollar to establish an official exchange rate of around 800 pesos per U.S. dollar. The adjustment of the exchange rate was intended to serve as a supplementary anchor for inflation expectations. Based on the current situation, the exchange rate devaluation path is currently set at 2% per month by the government. Throughout 2024, the BCRA actively intervened in both the official and parallel foreign exchange markets, including by selling U.S. dollars in the parallel market, in an effort to curb inflation, stabilize the monetary base, and close the gap between Argentina's official peso exchange rate and the Blue Chip Swap (BCS) rate (a parallel exchange rate). By December 2024, the gap had narrowed significantly, reaching a historic low of around 1.45%.

Brazil

The Central Bank of Brazil ("BCB") operates, consistent with the inflation targeting rate, a free floating foreign exchange regime that aims to reduce excessive volatility, although intervention has become more regular in recent years. The BCB regulates all currency inflows and outflows in Brazil, and the country's foreign exchange regime does not permit free convertibility of the currency. Nevertheless, the BCB does not directly determine the exchange rate. The Brazilian Real is fully deliverable onshore (i.e., physical settlement of the designated currency at maturity), but is non-deliverable offshore. As a result, foreign currency transactions must be executed with an institution authorized by the BCB to carry out such transactions, which is responsible for ensuring compliance with the local foreign exchange regulation. With proper documentation, the repatriation of registered invested capital and remittance of profits do not require prior approval from the BCB. Profits can be freely remitted as dividends or as interest on capital to foreign shareholders or portfolio investors.

China

China's foreign exchange regime has undergone significant liberalization in recent years. The People's Bank of China ("PBOC") maintains the Chinese renminbi in a managed float with reference to a basket of currencies. The CNY, which refers to the Chinese renminbi on the onshore market, is partially convertible and has a non-deliverable offshore market. CNY foreign currency spot transactions under \$50,000 per year do not require supporting documents. All onshore transactions involving foreign exchange are strictly controlled by the State Administration of Foreign Exchange. The foreign currency exchange fixing rate is announced every morning at 9:15 Beijing time, and the interbank market is only allowed to trade within 2% of the fixing rate for onshore CNY versus U.S. dollar. Since 2021, repatriating capital or profits out of China includes increased layers of inspection and security from the government. The PBOC has decided to increase the amount of foreign-currency deposits that financial institutions need to hold as reserves, as from June 2021, in order to curb sell-offs of foreign currencies after the renminbi's value climbed to a record high. The CNH, which is the Chinese renminbi traded offshore, became deliverable in Hong Kong in July 2010. The CNH can generally be transferred freely between offshore accounts and interaction with the onshore market is growing, although transfers of CNH from Hong Kong to onshore China are subject to regulations and approval by the PBOC. Moreover, in July 2020, integration of the interbank and exchange bond markets, as well as wider participation in the treasury bond futures market, suggest that more progress is likely to be made by the PBOC to move toward increased internalization of the Chinese market.

India

The Reserve Bank of India ("RBI") maintains the Indian rupee ("INR") in a managed floating regime. The INR is partially convertible and has a non-deliverable offshore market.

Onshore deliverable forwards are also available out to 10 years. The most common and liquid tenor in the forwards market is one year or less. The RBI monitors the value of the INR against the REER (Real Effective Exchange Rate). The INR exchange rate is determined in the interbank foreign exchange market. The INR is convertible for exports and imports of goods and services as well as unilateral transfers, including repatriating profits from foreign-funded companies, as well as for daily recurring transactions in the ordinary course of business. However, the INR is restricted on capital accounts (purchase and sale transactions of foreign assets and liabilities) and there are specific transactions that have to be authorized by the RBI or other relevant government departments for routine capital account transactions, e.g. foreign currency borrowings under the approval route or foreign direct investments that are not permitted under the automatic route. A daily benchmark fixing is published by the Financial Benchmark of India Limited for INR against U.S. dollar, EUR, JPY and GBP. Other permitted capital account transactions that are allowed, subject to compliance with local applicable regulations, include foreign direct investment, foreign currency loans and bonds, securities and equity investments overseas.

South Africa

The South African Reserve Bank ("SARB") operates a managed floating exchange rate system. The South African rand ("ZAR") is deliverable and largely convertible, and the SARB is gradually relaxing exchange rate controls. The currency is deliverable and traded out to 10 years, although liquidity is highest in tenors of two years or less. Since January 1, 2014, companies may apply for approval to establish a holding company to hold their offshore investments. Subject to certain conditions, listed companies may place ZAR 5 billion per year with such holding companies, which can be transferred offshore without exchange control approval, and unlisted companies may transfer ZAR 3 billion per year. All funds transferred into or out of South Africa must be declared to the SARB. Active currency hedging with maturity of more than 12 months requires documentary evidence of firm and ascertainable commitment. In most cases, there are no restrictions on capital inflows. However, all incoming loans are subject to the SARB's approval and institutions' overseas investments are restricted to 25% of retail assets for retirement funds and long-term insurers.

Ukraine

The National Bank of Ukraine ("NBU") is responsible for the country's monetary policy. Due to the ongoing war with Russia since the end of February 2022, on shore liquidity on Ukrainian Hryvnya has been significantly reduced, leading to the NBU implementing strong regulation to control foreign exchange transactions.

As of 2024, the National Bank of Ukraine (NBU) has introduced important updates to its foreign exchange regulations. These updates include easing restrictions on import payments and dividend repatriation, permitting currency transfers for international technical assistance, and facilitating VAT payments for e-commerce within the EU. Additionally, new limits have been set to reduce unproductive capital outflows, and restrictions on using foreign currency loans for purchasing securities have been tightened. These measures aim to maintain economic stability, support business operations, and effectively manage foreign currency reserves.

Disclosure pursuant to Section 219 of the Iran Threat Reduction & Syria Human Rights Act (ITRA) regarding ArcelorMittal's business with customers in Iran

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the U.S. Securities Exchange Act of 1934, as amended (the Exchange Act). Section 13(r) requires an issuer to disclose in its annual reports whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran. Disclosure is required even where the activities, transactions or dealings are conducted outside the United States by non-US persons in compliance with applicable law, and whether or not the activities are sanctionable under U.S. law.

In 2024, neither ArcelorMittal nor any of its affiliates engaged in activities, transactions or dealings relating to Iran requiring disclosure under Section 13(r).

ArcelorMittal continues to monitor developments in this area, in particular the status of U.S. sanctions, the Joint Comprehensive Plan of Action ("JCPOA") and EU sanctions, and the expansion of the EU Blocking Regulation (Council Regulation (EC) 2271/96). ArcelorMittal carefully monitors political risk and sanctions exposure and has procedures and systems in place intended to manage those risks.

However, ArcelorMittal's business is subject to an extensive, complex and evolving regulatory framework. It is possible that ArcelorMittal may face conflicting obligations or risks under U.S. direct and secondary sanctions and the EU Blocking Regulation, or other conflicting instruments. Despite its governance, compliance policies and procedures and continuous efforts to comply with all applicable sanctions regimes, its systems and procedures may not always prevent the occurrence of violations which may lead to regulatory penalties or cause reputational harm to operating subsidiaries, joint ventures or associates. See "Introduction—Risk Factors and Control."

Organizational structure

ArcelorMittal is a holding company with no business operations of its own. All of ArcelorMittal's significant operating subsidiaries are indirectly owned by ArcelorMittal through intermediate holding companies. The following chart represents the operational structure of the Company, including ArcelorMittal's significant operating subsidiaries or business divisions and not its legal or ownership structure.

Please refer to the "Glossary—definitions, terminology and principal subsidiaries" for a listing of the Company's principal subsidiaries, including country of incorporation. Please refer to note 2.2.1 of the consolidated financial statements for the ownership percentages of these subsidiaries. Unless otherwise stated, the subsidiaries as listed have share capital consisting solely of ordinary shares, which are held directly or indirectly by the Company and the proportion of ownership interests held equals to the voting rights held by the Company.

Investments in joint ventures

Reportable segments

ArcelorMittal reports its business in the following six reportable segments corresponding to continuing activities: North America, Brazil, Europe, India and joint ventures ("JVs"), Sustainable Solutions and Mining. The Company's operations in South Africa and Ukraine are included in Others.

As from January 1, 2024, ArcelorMittal implemented changes to its organizational structure. India and JVs are reported as a new operating segment that includes the joint ventures AMNS India, VAMA and AMNS Calvert, as well as other associates, joint ventures and other investments. The segment Sustainable Solutions is composed of a number of businesses playing an important role in supporting climate action (including renewables, special projects and construction business). Such businesses were previously reported within the Europe segment and are now reported as a separate operating segment. The NAFTA segment has been renamed North America. Finally, following the sale of the Company's operations in Kazakhstan, the remaining parts of the former ACIS segment were assigned to Others.

North America produces flat, long and tubular products. Flat products include slabs, hot rolled coil, cold rolled coil, coated steel products and plate and are sold primarily to customers in the following sectors: automotive, energy, construction, packaging and appliances and via distributors and processors. Flat product facilities are located at two integrated and minimill sites located in two countries. Long products include wire rod, sections, rebar, billets, blooms and wire drawing. Long production facilities are located at two integrated and mini-mill sites located in two countries. In 2024, shipments from North America totaled 10.1 million tonnes (10.6 million tonnes in 2023). The raw material supply of the North America operations includes sourcing from iron ore captive mines in Mexico to supply the steel facilities.

Brazil produces flat, long and tubular products. Flat products include slabs, hot rolled coil, cold rolled coil and coated steel. Long products comprise sections, wire rod, bar and rebars, billets and wire drawing. These products are sold primarily to

customers in the construction, power generation and agribusiness sectors, as well as in the automotive and household appliances industries.

AMNS India

AMNS India is an integrated flat carbon steel manufacturer from iron ore to ready-to-market products with achievable crude steel capacity of 8.8 million tonnes per annum. Its manufacturing facilities comprise iron making, steelmaking and downstream facilities spread across India.

In 2019, ArcelorMittal and Nippon Steel Corporation ("NSC"), Japan's largest steel producer and the third largest steel

producer in the world, created a joint venture to own and operate AMNS India with ArcelorMittal holding a 60% interest and NSC holding 40%. Through the agreement, both ArcelorMittal and NSC are guaranteed equal board representation and participation in all significant financial and operating decisions.

AMNS India's main steel manufacturing facility is located at Hazira, Gujarat in western India. It also has:

• two iron ore beneficiation plants close to the mines in Kirandul and Dabuna, with slurry pipelines that then transport the beneficiated iron ore slurry to the pellet plants in the Kirandul-Vizag and Dabuna-Paradeep systems;
• downstream facilities in Pune, Khopoli and Gandhidham; and
• six service centers in the industrial clusters of Hazira, Indore, Bahadurgarh, Chennai, Kolkata and Pune. It has a complete range of flat rolled steel products, including value added products, and significant iron ore pellet capacity with two main pellet plant systems in Kirandul-Vizag and Dabuna-Paradeep, which have the potential for expansion. Its facilities are located close to ports with deep draft for movement of raw materials and finished goods.

In terms of iron ore pellet capacity, the Kirandul-Vizag system has 8 million tonnes of annual pellet capacity; and the Dabuna-Paradeep system has 12 million tonnes of annual pellet capacity.

AMNS India completed the acquisition of the portfolio of strategic infrastructure assets from Essar Group. The remaining assets which were pending due to regulatory approvals have been acquired during 2024 and include a 16 million-tonne per annum all-weather, deep draft terminal at Visakhapatnam, Andhra Pradesh (along with an integrated conveyor connected to AMNS India's iron ore pellet plant in the port city) and a 100-kilometer Gandhar - Hazira transmission line, connecting AMNS India's steelmaking complex with the central electricity grid.

The resolution plan submitted for the acquisition of AMNS India in 2018 included a capital expenditure plan of approximately \$2.6 billion to be implemented in two stages over 6 years. The first stage involves investments which increase production of finished steel goods to 7.6 million tonnes per annum. It includes capital expenditure projects with respect to third line CSP caster (completed), Paradeep pellet plant (completed), as well as coke oven, second sinter plant and Dabuna beneficiation plant (in progress). The first stage also includes investment in maintenance to restore current assets, the implementation of an environmental management plan and the implementation of ArcelorMittal's best practices on raw material sourcing, plant operations, sales and product mix (in particular through greater sophistication of the quality and markets of the steel produced with a focus on developing sales to the automotive industry), people management and health & safety. The second stage involving capital expenditure projects to increase the production of finished steel goods from 7.6 million tonnes per annum to 8.6 million tonnes per annum is now included in the expansion

investment plan launched in October 2022 as described below.

AMNS India intends to further debottleneck existing operations (steel shop and rolling parts) in the medium term. The first phase of expansion represents capital expenditures of approximately \$7.7 billion (\$0.8 billion for debottlenecking, \$0.2 billion for operational readiness, \$1.0 billion for downstream projects and \$5.7 billion for upstream projects) and started in October 2022. It aims to increase production at the Hazira facility to 15 million tonnes of rolled products by the second half of 2026 (phase 1) following the construction of two blast furnaces (blast furnace 2 to start in 2025 and blast furnace 3 in 2026), the capacity increase of the existing blast furnace 1 from 2.2 to 2.8 million tonnes per annum and it includes also a cold rolling mill 2 complex and galvanizing and annealing line, steel shop, hot strip mill and ancillary equipment (including coke, sinter, networks, power, gas, oxygen plant, etc.) and raw material handling. Continuous galvanizing line No. 4 was commissioned in December 2023, which will enable AMNS India to launch the Magnelis product for the growing renewable energy sector. Plans are under development to expand the production capacity further. As per phase 2, steelmaking capacity would grow to 18 million tonnes per annum by 2028 and as per phase 3 production capacity would further increase to 24 million tonnes. Additionally, greenfield development options are under consideration to take steelmaking capacity to 40 million tonnes per annum in the long-term. See "—Capital expenditures".

In terms of mining assets, AMNS India operates the Thakurani mine in the Keonjhar district of Odisha and the Ghoraburhani-Sagasahi mine in the Sudargarh district of Odisha. The Thakurani mine is operating at full 5.5 million tonnes per annum capacity and concentrated material is transported by pipeline from the Dabuna plant to the Paradeep pellet plant, located on the coast at Bay of Bengal. AMNS India commenced the operations at the Ghoraburhani-Sagasahi iron ore mine in September 2021. The mine is set up to gradually ramp up production until 2026 to a rated capacity of 7.2 million tonnes per annum. The iron ore final product is supplied to the beneficiation plant in Dabuna from where the feed reaches the pellet plant at Paradeep and contributes significantly to meeting AMNS India's long-term raw material requirements. For further details on Indian mines production and other information, see " —Mineral reserves and resources".

*Ongoing projects refer to projects for which construction has begun (excluding various projects that are under development).

• a. The Vega Do Sul expansion project targets the growing domestic market with an approximately \$0.4 billion investment. It includes an option for a 100,000-tonne organic coating line for construction and appliances. Upon completion, it will strengthen ArcelorMittal's position in the automotive and industrial markets with AHSS products. The pickling line and tandem cold mill produced their first coil in June 2023, followed by the first continuous annealed commercial coil in June 2024. Coated production (GI) began in July 2024, Magnelis trials in September 2024, and the CGLCAL PAC-Provisional Acceptance Certificate was issued on December 16, 2024.
• b. See "Business overview—Sustainable development—Climate change and decarbonization".
• c. AMNS Calvert is constructing a new 1.5 million tonnes EAF and caster. The facility is currently in the hot commissioning phase. The new EAF project with investment over \$1 billion, integrated with ArcelorMittal's HBI facility in Texas, will enable Calvert to supply automotive customers with lower CO2 embodied steel, melted and poured in the U.S. The new EAF has a strong product mix of advanced steel grades, including Exposed, Dual Phase (DP), Multiphase (MP), Third Generation (Gen-3) steels and Press Hardened Steels (PHS) namely Usibor®. Option to add a further 1.5 million tonnes EAF at lower capital expenditure intensity is being studied.
• d. The Serra Azul project's current investment forecast is approximately \$0.5 billion. The DRI quality pellet feed is expected to primarily supply ArcelorMittal Mexico steel operations. Completion is delayed by 1 year mainly due to delayed delivery of equipment.
• e. Approximately \$0.3 billion investment in the Barra Mansa (Brazil) sections mill aims to expand domestic market share and profitability with higher added value ("HAV") products like merchant and special bars. Project completion is now expected in the second half of 2025 as a result of unforeseen challenges during civil works.
• f. ArcelorMittal, with French government support, is establishing a new electrical steels production unit at Mardyck, complementing its Saint-Chély d'Apcher plant. The \$0.5 billion investment will be completed in two phases: commissioning and ramp-up of the annealing and coating line in the first half of 2025, followed by APL and REV startup in the second half of 2025. The delay from the initial timeline is due to unforeseen civil construction challenges and resource constraints among main contractors.
• g. ArcelorMittal Liberia has been operating at 5 million tonnes per annum of direct shipping ore (DSO) since 2011 (Phase 1) and restarted construction of a concentrator and associated infrastructure (Phase 2). Project commissioning ongoing with most procurement and civil works completed in 2024 (with minor areas still to be concluded) and structural, mechanical, piping and platework well progressed. An opportunity to increase port shipment capacity to 20 million tonnes per annum led to a revised project capital expenditure of \$1.8 billion (previously \$1.4 billion), reflecting a multiple product approach (sinter feed and concentrate) following revised mining plan and additional investment in material handling, port infrastructure, covered stockpile and power supply. The revised scope allows for an additional 5 million tonnes per annum of blended product, bringing total shipment capacity to 20 million tonnes per annum (previously 15 million tonnes per annum). By blending a portion of the new concentrate with crushed ore product, a sinter feed blend (>62% Fe) can be produced, increasing Liberia's marketable production. Of the targeted 20 million tonnes, 75% or 15 million tonnes of sinter feed is to be made up of a blend of 10 million tonnes concentrate and 5 million tonnes of crushed ore, and remaining 25% or 5 million tonnes is to be represented by high-grade concentrate. First concentrate was produced during commissioning activities in the fourth quarter of 2024, with commissioning targeted for mid-2025 and full project completion and capacity ramp-up expected in the fourth quarter of 2025. Approximately 10 million tonnes of shipments are targeted in 2025 (with the majority of shipments expected in the second half of 2025). In addition, a phased plan to expand capacity up to 30 million tonnes per annum, including DRI-quality concentrate is under study.

• h. Approximately \$0.2 billion investment project will enable concentrate production to the blast furnace route (2 million tonnes per year) and DRI route (0.3 million tonnes per year) for a total of 2.3 million tonnes per year. Primary target is to supply ArcelorMittal Mexico steel operations with high quality feed. Due to delay in equipment delivery and construction works, amplified by the strike/illegal blockade of the mine in the second and third quarters of 2024. production is expected to start in the first half of 2026.

• i. AMNS India medium-term plans are to expand and grow initially to approximately 15 million tonnes by the second half of 2026 in Hazira (phase 1) including automotive downstream and enhancements to iron ore operations, with estimated capital expenditure of approximately \$7.7 billion (\$0.8 billion for debottlenecking, \$0.2 billion for operational readiness, \$1.0 billion for downstream projects and \$5.7 billion for upstream project). Studies for options to further expand capacity at Hazira from 15 million tonnes to ultimately reach 24 million tonnes are in progress. Also,the development of two greenfield options on the East Coast (Paradeep and Kendrapara) to take overall capacity above 40 million tonnes is under study.

• j. See "Introduction—Sustainable developments highlights"

In addition, in 2024, the Company approved 17 multi-year projects with identified environmental benefits and involving capital expenditures of \$219 million and 32 multi-year projects with identified energy benefits and involving capital expenditure of \$326 million. The latter also includes 11 multiyear projects specifically targeted to decarbonization involving capital expenditures of \$146 million. Capital expenditures related to decarbonization initiatives amounted to \$0.3 billion for the year ended December 31, 2024 and are expected to remain stable between \$0.3 to \$0.4 billion in 2025, with main spend focusing on continuation of engineering studies on DRI-EAF facilities in Europe (flat products), implementation of new EAF project in Gijón (long products) with total expected investment of \$0.2 billion and EAF capacity expansion in Sestao (flat products) with total expected investment of \$0.1 billion, as well as new DR pellet project in AMMC.

Peña Colorada

Peña Colorada is the operator of a production stage surface iron ore mine, located 60 kilometers to the north-east of the port city of Manzanillo, in the province of Minatitlán in the north-western part of the State of Colima, Mexico. ArcelorMittal holds 50% of Peña Colorada through a joint operation with Ternium, who owns the other 50% interest.

Peña Colorada controls a total of 4,167 hectares of surface rights and holds mineral rights over 39,978 hectares (98,791 acres) across 20 concessions. According to new regulations, government concessions are granted by the Mexican federal government for an initial period of 30 years. However, the applicability of this new regulation to Peña Colorada is subject to pending governmental procedures as of the date of this annual report. The expiration dates of the current mining concessions range from 2043 to 2062.

Peña Colorada is a complex polyphase iron ore deposit. The iron mineralization at Peña Colorada consists of banded to massive concentrations of magnetite within breccia zones and results from several magmatic, metamorphic and hydrothermal mineralization stages with associated skarns, dykes and late faults sectioning the entire deposit.

Peña Colorada operates an open pit mine as well as a concentrating facility and a two-line pelletizing facility. The ore is mined by truck and shovel/loader method. The beneficiation plant and the pelletizing plant are located at the mine and in

Manzanillo, respectively. Major processing facilities include a primary crusher, a dry cobbing plant, two autogenous mills, three horizontal and two vertical ball mills and several stages of magnetic separation. The concentrate is sent as a pulp through a pipeline from the mineral processing plant to the pelletizing facilities. The magnetite concentrate and pellets are transported from Manzanillo to ArcelorMittal Mexico, as well as to Ternium's steel plants, by ship and by rail.

Las Truchas

Las Truchas is a production stage mine located approximately 27 kilometers north-west of the town of Lázaro Cárdenas in the State of Michoacán, Mexico. ArcelorMittal holds a 100% interest.

ArcelorMittal Mexico holds mineral rights over 53,812 hectares, of which 4,261 support the Las Truchas operations in Mexico. Government concessions are granted by the Mexican federal government for a period of 50 years and are renewable. The expiration dates of the current mining concessions range from 2044 to 2053.

The Las Truchas deposits consist of massive concentrations of magnetite of irregular morphology. The main Las Truchas deposits occur along a geological trend that is about seven kilometers long and about two kilometers wide. The Las Truchas mineral deposits have been classified as hydrothermal deposits, which may have originated from late-stage plutonic activity injecting through older sedimentary rocks. The mineralization of the Las Truchas iron deposits occurs in disseminated and irregular massive concentrations of magnetite within

metamorphic rocks and skarns. The mineralization also occurs as fillings of faults, breccia zones, and fractures.

Mining activities consist of open pit mining, crushing, dry cobbing to generate pre-concentrate, and a concentration plant.

The concentrator includes two primary crushers, two secondary crushers and three tertiary crushers, two ball mills, two bar mills and two wet magnetic separation circuits. The concentrated ore is pumped from the mine site through a 26 kilometer slurry pipeline to the steel plant facility in Lázaro Cárdenas.

ArcelorMittal Mexico launched a project to increase pellet feed production to 2.3 million tonnes per annum and improve concentrate grade in Las Truchas; see "—Capital expenditures".

San José

The San José mine ceased its operations in 2024 due to the depletion of resources, as such there have been no mineral reserves or resources estimated for this property. It is located approximately 40 kilometers South-East of the town of Culiacán, the capital of the State of Sinaloa, México. Mining at San José began in 1946 and was handled by multiple owners until 2019, when ArcelorMittal secured a lease agreement and commenced mining and pre-concentration operations. ArcelorMittal's interest in the San José mine is 100%.

ArcelorMittal Mexico holds mineral concessions for 30 hectares which supported its now closed San José operations. Additionally, ArcelorMittal Mexico holds mineral rights over 1,053 hectares which previously supported its now closed El Volcan operations, located approximately 68 kilometers northwest of the city of Obregon.

ArcelorMittal Mexico has a lease agreement secured from Ejido Las Flechas, for both the land and the San José facilities, which is in place for a period of ten years and is valid until 2028. Previous mine operators have secured surface rights to the project from the Ejido in the past and it is reasonable to assume that ArcelorMittal Mexico can continue to secure surface rights beyond 2028.

Andrade Mine

The Andrade Mine is a production stage open pit iron ore mine, located 5 kilometers away from the town of João Monlevade and 80 kilometers east of Belo Horizonte in the Brazilian state of Minas Gerais. The Andrade mine is 100% owned and operated by the Long products division of ArcelorMittal Brasil, with all production supplying the Monlevade steel plant.

ArcelorMittal's operations control all of the mineral rights and surface rights needed to mine and process its estimated iron ore reserves, dominated by directly shippable hematite ore. ArcelorMittal Brasil holds mineral rights of over 2,885 hectares and land lease over 3,347 hectares to support its current operation. Mining legislation in Brazil does not predetermine the duration of mineral rights and as such these rights are considered valid to the point of mine exhaustion.

The Andrade deposit is located in the north-eastern part of the Iron Quadrangle. The base stratigraphic section consists of quartzites and sericite-quartzites of the Moeda formation,

followed by schists of the Batatal formation, both forming the Caraça group. The iron rich mineral bodies are part of the overlying Cauê formation, which represents the base of the Itabira Group. The Caraça and Itabira groups compose the base of the Paleoproterozoic Minas Supergroup. The Cauê formation rocks are covered by dolomites and marbles, and sometimes weathered phylites and schists, belonging to the Gandarela formation.

In addition to the open pit mine, the Andrade mine operates a crushing and screening facility, as well as a concentration plant used to improve the quality of the sinter feed to the Monlevade plant. This concentration plant commenced production in early 2020 and concentrates the itabirite ores, enabling mixing with the higher-grade hematite ores. The concentrated iron ore product is transported to the Monlevade steel plant through a private railway line.

In 2022, the resource model of Andrade has been updated, resulting in a new pit optimization and mine schedule, with

updated Life of Mine schedule for the Itabirite and Hematite ores. The new life of mine extends to 2054, with increased annual ROM capacity up to 4.5 million tonnes after 2027.

Serra Azul Mine

ArcelorMittal Mineração Serra Azul mine is a production stage open pit iron ore mine located approximately 70 kilometers southwest of Belo Horizonte in the Minas Gerais State of Brazil. The mine is 100% owned and operated by ArcelorMittal Brasil.

ArcelorMittal Brasil controls all of the mineral and surface rights needed to mine and process its iron ore reserves. ArcelorMittal Brasil holds mineral rights over the Central and East claims of the Serra Azul deposit of over 375 hectares and surface rights over 288 hectares. Mining legislation in Brazil does not predetermine the duration of mineral rights and as such these rights are considered valid to the point of mine exhaustion.

The Serra Azul mine is located in the western part of the Iron Quadrangle, in the iron rich Cauê Formation of the Itabira Group. The mineralization occurs as friable, semi compact and compact itabirites and banded hematite-silica rocks, with varying degrees of weathering and oxidation. Currently, Serra Azul mines and processes the friable itabirite with the Serra Azul expansion project (see "—Capital expenditures") contemplating the mining and processing of semi-compact and compact ores.

The Serra Azul mine also operates a processing plant consisting of a crushing facility and a three-line concentration facility, including screening, magnetic separation, spirals separators and jigging. Iron ore product is transported by truck to two railway terminals located 35 and 50 kilometers from the mine site for distribution to local purchasers of sinter feed or for export through third-party port facilities located in the Rio de Janeiro State.

In 2021, an updated resource model was generated, incorporating the results of a 1,508 meter drilling program completed in late 2020. The drilling program targeted further definition of the friable itabirite ("IF") ore bodies and the updated model has been used to reassess the mine life for the current IF phase of the Serra Azul Mine. This resulted in a revised life of mine for the IF phase, with mining operations extended until the end of 2024. After finalizing the IF phase, the mine will pause its production until the IC and ISC processing plant operations start in second half of 2025.

Following the integration of the Serra Azul Mine into ArcelorMittal Brasil in 2020, an expansion project for the Serra Azul Mine was approved, extending the mine's life until 2058. The project considers producing 4.5 million tonnes per annum of DRI quality pellet feed by processing compact itabirite ("IC") and semi-compact itabirite ("ISC") material. The IC and ISC processing plant operations are scheduled to start in the second half of 2025 (see also "—Capital expenditures).

In February 2019, the Company decided to implement the evacuation plan related to its dormant Serra Azul tailing dam. The community situated downstream to the dam was evacuated as a precautionary measure based on an updated stability report following incidents in the Brazilian mining sector. This was done to enable further testing and implementation of any additional mitigating measures. As a result, the Company has executed an agreement with the Federal and State Public Prosecutors Offices and affected families to provide temporary assistance to the families and set technical measures required to re-establish factor of safety standards. Such agreement was extended in February 2020 and negotiations regarding compensation continued in 2021, during which a Complementary Agreement Term was signed with new guidelines for compensation parameters for the impacts caused by preventive evacuation. As of December 31, 2024, the Company had entered into 942 indemnification agreements with the affected families. The agreement contemplates the construction of a check dam structure by the end of 2025 and the tailing dam deconstruction by 2032.

ArcelorMittal Prijedor

The Omarska mine is a production stage surface iron ore mine in Bosnia and Herzegovina, operated by ArcelorMittal Prijedor. The mine is located 25 kilometers south-east of the town of Prijedor. ArcelorMittal Prijedor was founded in 2004 as a partnership between ArcelorMittal (at the time LNM Holdings) with a 51% controlling interest and local mining company Iron Ore Mine Ljubija owning the remaining 49% stake. ArcelorMittal Prijedor is a captive mine of the Europe segment and supplies all of its iron ore production to the ArcelorMittal Zenica steel plant.

In 2022, ArcelorMittal Prijedor acquired additional mining and land rights and started iron ore mining on a trial basis at Ljubija Mine. Product from Ljubija mine is supplied to ArcelorMittal Zenica steel plant where it is blended with the product from Omarska mine.

The Omarska mine's current concession was signed in 2018 for a period of 6 years and the renewal process is ongoing as of the date of this annual report. The property comprises 1,946 hectares of land and mineral rights. The Ljubija mine's current concession was signed in 2022 for a period of 6 years, with an option to renew upon the expiry, in accordance with updated life of mine. The property comprises 739 hectares of land and mineral rights. ArcelorMittal Prijedor is the registered holder of the mining rights at the Omarska mine exploitation field. Land tenure and mineral rights issued to ArcelorMittal Prijedor are indefinite and considered to be of sufficient duration to enable all reported mineral reserves on the properties to be mined in accordance with current life of mine production schedules.

The Buvac deposit at the Omarska mine is located within Carboniferous clastic (shale and sandstones) and carbonate (limestone, dolomite, and ankerite) sequences, with massive siderite-limonite mineralization forming an integral part of the formation. Iron ore from the Buvac deposit is predominantly limonite-goethite with associated quartz, carbonates, and silicates of the illite type. The limonite-goethite mineralization was formed during the oxidization of the upper parts of the primary siderite bodies.

The ore body is asymmetrical, lens-shape and elongated in a northeast - southwest direction, dipping at about 8° toward the north-east from the surface to a depth of 210 meters. The deposit is approximately 1.5 kilometer long and 1.0 kilometer wide.

The Ljubija deposit is located within Carboniferous and Permian-Triassic formation rocks which are partly covered by thin Quaternary rocks. The ore within these formations is primarily composed of siderite and ankerite with secondary limonite iron facies.

The ore is excavated from the Omarska and Ljubija deposits by traditional truck and shovel open pit mining methods. At the Omarska mine, after a primary stage of crushing within the pit, the ore is transported to a processing plant via a conveyor. The processing plant on site performs crushing, screening, gravity separation, magnetic separation and filtration. At the Ljubia mine, ore is only crushed and screened.

ArcelorMittal Kryvyi Rih

AMKR is a production stage iron ore mining complex located predominantly within the borders of the city of Kryvyi Rih, 150 kilometers southwest of Dnipro, Ukraine. The mine is 95.1% owned by ArcelorMittal and is integrated into the ArcelorMittal Kryvyi Rih steel business as a captive mine. ArcelorMittal acquired the operations in 2005.

AMKR operates two open pits over the Novokryvorizke (Mine 2 on the map) and Valyavkinske (Mine 3 on the map) deposits, and an underground mine at the high-grade iron ore deposit of Kirova. Operations began at the Kryvyi Rih open pit mines in 1959 and at the Kryvyi Rih underground mine in 1933.

AMKR's operations control all of the mineral rights and surface rights needed to mine and process its estimated iron ore reserves, holding mineral rights over 775 hectares and surface rights over 4,827 hectares to support its surface operations, and 57.9 hectares of mineral and 160 hectares of surface rights for the underground mine operation. The subsoil use permits for the underground mine were renewed in 2021 for the next 20 years, and for the surface pits, mineral rights are due to expire in 2038, with the land lease agreements being valid until 2060 and 2061, respectively.

The iron ore deposits are located within the southern part of the Krivorozhsky iron-ore basin. The iron mineralization at Novokryvorizke and Valyavkinske deposits is hosted by early Proterozoic rocks containing multiple altered ferruginous

quartzite strata with shale layers. The major iron ore bearing units in the open pit mines have a carbonate-silicate-magnetite composition. In addition, oxidized, iron-rich quartzite is mined simultaneously with primary ore and is stored separately for possible future processing. Only the magnetite mineralization is included in the 2024 open pit iron ore reserve estimates. The high-grade iron ore of the Kirova deposit is hosted by a ferruginous quartzite with martite and jaspilite.

Along with the two open pit sites and an underground mine, AMKR operates a concentrating facility and a crushing facility to produce its final product. The iron ore extracted from the open pits is crushed at the mine site through primary crushing, loaded on a rail-loading facility and transported to the concentrator. The concentration facility includes crushing, grinding, classification, magnetic separation and filtering. The iron ore is extracted from the underground mine by a modified sub-level caving method and is crushed and screened at surface into lump and sinter ore, before being transported by rail to the steel plant. The AMKR steel plant is the main consumer of the mine's products.

As a result of the ongoing war in Ukraine, iron ore production was planned according to the consumption at AMKR steel plant and logistics availability. In 2024, open pit iron ore production was at approximately 75% of its maximum capacity (as compared to approximately 45% in 2023). Mining at open pit continued without stoppages in 2024. There have been temporary stoppages at the underground mine in the first quarter of 2023, the first quarter of 2024 and the underground

mine has been idled since September 2024, due to lower demand for sinter ore. In 2024, iron ore production at the underground mine was at approximately 26% of its maximum capacity (as compared to 40% in 2023).

South Africa

The Thabazimbi mine in the Limpopo Province of South Africa is an exploration stage captive mine of ArcelorMittal South Africa ("AMSA") steel. AMSA took full ownership of the Thabazimbi operations from Kumba Iron Ore in November 2018.

Open pit operations at Thabazimbi ceased in 2016, and the mine is currently only engaged in the rehandling of iron ore from stockpiles of ROM material from historical production.

The Thabazimbi mine holds surface rights over 10,952.8 hectares and mineral rights over 8,662.3 hectares, valid until 2039. Further studies to define mineral reserves and the life of the mine will be undertaken in 2025.

The Vanderbijl iron ore deposit at Thabazimbi, for which the resources are estimated, is located on the northern margin of the Transvaal sub-basin. The Transvaal Supergroup was deposited in an open marine sedimentary basin developed on the Kaapvaal Craton within fluvial, deltaic to marine depositional environments. The iron ore deposits are developed at or close to the transitional contact zone of the combined footwall dolomites and upper transitional shale beds (including the overlying an approximately 15 meter thick chert-rich shale layer) of the Malmani Subgroup and the overlying BIFs of the Penge Formation.

AMMC

AMMC is structured in two partnerships ArcelorMittal Mining Canada G.P. and ArcelorMittal Infrastructure Canada G.P., which are both held at 85% by ArcelorMittal with a 15% noncontrolling interest held by 9404-5515 Québec Inc., a consortium constituted, among others, of POSCO, South Korean Steel Company and China Steel Corporation.

AMMC is a production stage property, including two deposits at Mont-Wright and Fire Lake, and another deposit at Mont-Reed. The mines at Mont-Wright and Fire Lake are operated by AMMC and are both open-pit producing mines, consolidated in one production schedule and life of mine supporting the AMMC property's disclosed mineral reserves. The deposit at Mont-Reed is currently in an exploration stage.

The Mont-Wright and Fire Lake deposits are located in Québec, Canada. Mont-Wright is located near Fermont, and Fire Lake is located 85 kilometers south-east of Fermont. The Mont-Reed deposit is located approximately 130 kilometers southwest of Mont-Wright. Along with the Mont-Wright and Fire Lake mines, AMMC operates an ore processing plant located on-site at Mont-Wright, as well as a pelletizing plant located at the Port-Cartier port.

Headquarters of the mines are based in Greater Montreal. Fermont, the town site built to support the mining operations, is located 16 kilometers east of the Mont-Wright mining complex and is connected by Highway 389 to Baie-Comeau, which is 570 kilometers away. The Mont-Wright and Fire Lake mines are located approximately 400 kilometers north of the city of Port-Cartier and approximately 1,000 kilometers north-east of Montreal.

AMMC mining property comprises 38,748 hectares of mineral rights across six mining leases, five patented parcels and 698 map designated claims. Patented parcels have no expiration dates or lease fees whereas active leases are valid for a period of ten years. All current leases expire between 2025 and 2033 and can be renewed as needed, with reports on material moved disclosed to the government on a yearly basis.

The Mont-Wright, Fire Lake and Mont-Reed deposits are all Lake Superior–type banded iron formations, the metamorphic equivalent to other iron formations within the Labrador Trough iron district. While Mont-Wright and Fire Lake are hematite-rich deposits, Mont-Reed has a greater ratio of magnetite.

Mont-Wright and Fire Lake are surface pit producing mines, with the mining operations carried out in conventional large-scale open pits employing industry standard technology and equipment to mine ore with grades averaging approximately 29% Fe.

All mined ore from Mont-Wright and Fire Lake is processed at the Mont-Wright processing plant, with material from Fire Lake brought in by train. Feed ore material is fed through the crusher and concentrated in the processing plant in Mont-Wright using a gravity separation method. Concentrate is shipped to Port-Cartier, Québec, Canada, via private railroad, to the pelletizing facilities and port operations. The main products sold are concentrate and a variety of pellets.

AML

AML is an open-pit production stage property and has been mining direct shipping ore ("DSO") from the Mt. Tokadeh, Mt. Gangra, and Mt Yuelliton deposits in northern Liberia, since 2011. ArcelorMittal's ownership of AML is 85%, with the remaining 15% owned by the Liberia Government. The construction of the mine commenced in 1960 by a group of Swedish companies, which ultimately became the Liberian American-Swedish Minerals Company ("LAMCO"), and production commenced at the Nimba deposit in 1963. After

LAMCO ceased production in 1992, AML signed a Mineral Development Agreement (MDA) in 2005 with the Liberian Government. On December 28, 2006, AML signed the First Amendment to the MDA with the Liberian Government. On January 23, 2013, the parties signed the Second Amendment to the MDA.

Under the MDA, AML is currently developing three deposits located approximately 300 kilometers northeast of Monrovia, Liberia. Three deposits within the MDA are grouped under the name "Western Range Project", which includes the Mt. Tokadeh, Mt. Gangra and Mt Yuelliton deposits. The MDA, which is valid until 2030, grants a concession area to AML of approximately 51,342 hectares within which AML has the rights to explore or mine iron ore. Within the concession area, AML has a Class A mining license for the Mt. Tokadeh, Mt. Gangra and Mt Yuelliton deposits and a Mineral Exploration License for Mt. Blei and Mt Detton. In addition to the rights to explore and mine iron ore, the Liberian Government has granted the right to develop, use, operate and maintain the Buchanan to Yekepa railroad and the Buchanan port, along with an area at Buchanan for township and industrial facilities for material handling and workshops.

The Nimba range consists of itabirites in a 250 to 450-meterthick recrystallized iron formation. Although the iron deposits at Mt. Tokadeh, Mt. Gangra and Mt Yuelliton fit the general definition of itabirite as laminated metamorphosed oxide-facies iron formation, they are of lower iron grade than the ore previously mined at the Nimba deposit. Tropical weathering effects have caused the decomposition of the rock forming minerals resulting in enrichment in the iron content that is sufficient to support a DSO operation and accordingly, currently, only high-grade ore reserves of oxidized iron ore are mined. This ore only requires crushing and screening to make it suitable for export. The materials-handling operation consists of stockyards at both the mine and port areas, which are linked by a 250-kilometer single track railway running from Mt. Tokadeh to the port of Buchanan. The facilities at the port consist of tail pulley platforms, a conveyor system, a quayside including bays for iron ore storage, a fuel quayside jetty, an equipment workshop and the final product storage. The final product is primarily supplied to ArcelorMittal's steel plants in Europe, and any product balance is shipped to the external European market.

In 2013, AML began construction of a Phase 2 project that targeted 15 million tonnes per annum of concentrate sinter fines. This project was, however, suspended due to the onset of Ebola in West Africa and the subsequent force majeure declaration by the onsite contracting companies. AML completed a revised feasibility study, which was updated in 2019-2020, to apply best available technology and replace wet with dry stack tailings treatment. The Phase 2 expansion includes the construction of a concentrator plant with the ability to beneficiate oxidized and transitional ores and that targets 15 million tonnes per annum of premium iron ore concentrate.

Current plans aim to optimize the product mix and achieve a 20 million tonnes per annum production rate by the end of 2025. For the first five years, this is done by blending concentrate with 5 million tonnes per annum of crushed blend ore, which bypasses the concentrator. This crushed blend ore mixed with concentrate makes it suitable for sinter feed. The plan is to maintain these higher production rates, so ongoing studies are exploring options to expand the resource base of crushed blend ore, optimize mass recovery through the inclusion of regrinding and flotation circuits for the tailings, and increase concentrator capacity.

The concentrator phase, will transition AML to a premium product category (high-grade concentrate) asset while achieving a low FOB and CIF-China cost position (with the economies of scale projected to more than offset the cost of concentration). The expansion project, which encompasses processing, rail and port facilities, is one of the largest mining projects in West Africa. It is effectively a brownfield expansion, with 90% of the procurement already completed (with the equipment on site) and most civil works completed in 2024 (with minor areas still to be concluded), with structural, mechanical, piping and platework well progressed. First concentrate was generated during commissioning activities in the fourth quarter of 2024, full completion and continuous production is expected in 2025. The revised feasibility study also contemplates a future change to the processing infrastructure to enable the production of highquality concentrate from the magnetite dominant fresh ores (Phase 3).

Thakurani mine

AMNS India's Thakurani iron ore mine is a production stage open pit mine in the Odisha state of India. AMNS India holds surface and mineral rights over 228 hectares to support its Thakurani operations, located 320 kilometers to the north of the Odisha's capital Bhubaneswar and 4 kilometers east of the town of Barbil.

The operation and mining rights to the Thakurani operations were obtained by AMNS India in February 2020 through the Indian Government Mining Block auction scheme. The Thakurani open pit mine has been operated since 1961 and has both mature mining pits and undeveloped resource areas. AMNS India commenced mining operations in mid-2020, following the demobilization of the previous claim holder, Kaypee Enterprises.

AMNS India has a permit in place for 5.5 million tonnes per annum of ore production. The ramp-up to a capacity of 5 million tonnes per annum was completed in 2021. The mining lease deed was granted in 2020 for a period of 50 years. Until June 2021, all production from the mine had to be consumed by specified AMNS India end use plants, after which up to 25% of production may be sold to a third party. The permitted production rate was increased to 7.99 million tonnes per year from 2023 after a submission approved by the Indian Bureau of Mines in late 2020.

The Thakurani operations lie in the south-eastern part of the Singhbhum-Keonjhar-Bonai iron ore belt, a narrow NNE-SSW directional trending folded syncline that runs through northern Odisha, India and southern Jharkhand, India. The Precambrian horseshoe shaped belt is a well-known iron ore province hosting many iron ore deposits. The enriched sequence is a traditional Banded Iron Formation that has been subject to significant weathering that has enriched the iron ore deposits. Ore is generally of the friable hematite type, however more competent hematite ores and friable goethite ores are also present.

The current mining operation at Thakurani is being carried out by conventional mining methods using excavators and trucks for ore transportation to a mobile crushing facility. Ore from the Thakurani operation is crushed and screened on site before

being transported by road to the Dabuna beneficiation plant located approximately 40 kilometers to the south. Beneficiated material is then transported by slurry pipeline to the pelletizing plant at Paradip, located on the coast of Bay of Bengal.

Ghoraburhani – Sagasahi mine

The Ghoraburhani – Sagasahi mine is a production stage open pit iron ore mine, located in the Sundargarh district of Odisha, state of India. The operation and mining rights to the Ghoraburhani – Sagasahi operations were obtained through the AMNS India takeover of Essar Steel India Limited (ESIL) in December 2019. The mining lease deed was granted in 2021, for a period of 50 years and permits production of up to 7.16 million tonnes per annum of ore primarily for captive usage. AMNS India holds surface and mineral rights over 139 hectares at the Ghoraburhani – Sagasahi mine.

The Ghoraburhani – Sagasahi operations lie in the southwestern part of the Singhbhum-Keonjhar-Bonai iron ore belt. The enriched sequence is a traditional Banded Iron Formation that has been subject to significant weathering and deformation that has enriched the iron ore deposits. Ore is generally of lateritic iron ore/hard laminated ore on the top followed by soft laminated ore and friable hematite with intercalations of friable shaly ore and limonitic ore are also present.

Ore mining commenced at the Ghoraburhani – Sagasahi mine in 2021 by conventional mining methods, using excavators and trucks for ore transportation to a mobile screening & crushing facility, where ore is crushed and screened on site before being transported by road to the Dabuna beneficiation plant located approximately 28 kilometers to the south-east. Beneficiated material is then transported by 253 kilometers slurry pipeline to the pelletizing plant at Paradip.

The Mary River mine is a production stage open pit high-grade iron ore mine. The mine is operated by Baffinland Iron Mines Corporation, a privately owned Canadian mining company.

The Mary River property is located within the Arctic Circle on north Baffin Island, in the Qikiqtani Region of Nunavut, Canada, approximately 1,000 kilometers (620 miles) northwest of Iqaluit, the capital of Nunavut. It comprises five high grade deposits and six prospects, which represent high grade examples of Algomatype iron formation consisting of magnetite, hematite and specular hematite mineralization. The project began commercial production on Deposit No. 1 in 2014.

In March 2011, ArcelorMittal acquired 70% of the Mary River mine project, with Nunavut Iron Ore Inc. ("NIO"), an affiliate of The Energy and Minerals Group ("EMG"), owning the remaining 30%. In February 2013, ArcelorMittal and NIO entered into a joint arrangement and equalized their shareholdings at 50/50. Subsequently, following equity funding commitments and conversion of preferred shares into equity, both exercised by NIO only, ArcelorMittal's share over time decreased to 25.70% as of December 31, 2019 and 25.23% as of December 31, 2020. In September 2020, the corporate structure was reorganized whereby NIO became the sole parent company of Baffinland, while ArcelorMittal together with EMG became shareholders of NIO. Following this reorganization, ArcelorMittal retained its participation in the project and as of December 31, 2024, holds a 25.23% interest in NIO.

Baffinland's total mineral tenures (including mining leases, mineral claims and mineral exploration agreements) cover an area of approximately 269,187 hectares (665,176 acres). Of this, approximately 14% is subject to mining leases (being leased claims under the Nunavut Mining Regulations), 79% is covered by mineral claims (being recorded claims under the Nunavut Mining Regulations) and the rest by mineral exploration agreements.

Baffinland has two main operating locations – the mine site at Mary River and Milne Port, located approximately 86 kilometers north-west of the mine site. The Mary River mine is selfsustaining and is equipped with an airstrip and aerodrome. It is a conventional open pit truck and shovel operation. Ore is delivered to crushers before the crushed product is transported

via the 100 kilometer Tote road to Milne Port. Milne Port has been fully developed to accommodate a 5 million-tonne ore stockpile, an ore dock, maintenance facility, and associated infrastructure for the operation of the port facilities. Baffinland can only ship during the open water season (typically July to October), but may conduct haulage of ore to the port throughout the year.

In 2023, Baffinland operated within an approved Early Revenue Phase, which permitted up to 6.0 million tonnes per annum to be hauled to and shipped from Milne Port. The current permitting limit on trucking and shipping is 4.2 million tonnes per annum. In September 2023, Baffinland obtained continued approval for an increase to 6 million tonnes per annum for 2024.

Baffinland had approved a project involving the construction of a railway to replace the existing truck-haul operation for the transport of iron ore from Mary River to Milne Inlet, as well as the expansion of mining, crushing and screening operations and port ship loading capacity (the "Northern Rail Expansion").

On May 13, 2022, the Nunavut Impact Review Board ("NIRB") formally recommended that Baffinland's proposed Northern Rail Expansion not move forward at this time, citing potential environmental impact concerns on the local wildlife and culture, among other things. On November 16, 2022, the Minister of Northern Affairs accepted the NIRB's recommendation, and rejected Northern Rail Expansion.

Beginning in 2023, Baffinland's expansion activities and related capital expenditures have been primarily directed toward expanding the mining and processing operations at the Mary River mine site and connecting the mine site south to the Steensby port (for which it has already obtained the major permits) (the "Steensby Expansion"). Baffinland continues to advance the financing plans for the Steensby Expansion and expects the overall financing process to conclude in the second half of 2025.

Vallourec Mineração Pau Branco Mine

In August 2024, ArcelorMittal completed the acquisition of a 28.4% equity stake (27.9% as at December 31, 2024) in the associate Vallourec.

In Brazil, Vallourec extracts iron ore at its Vallourec Tubos do Brasil SA (VBR) Pau Branco open pit mine and these operations and structures are duly licensed. VBR's Mining Unit (formerly Vallourec Mineração Ltda.) has been extracting iron ore at its Pau Branco open pit mine since the early 1980s. The mine is located in the city of Brumadinho in the State of Minas Gerais, 30 kilometers south of Belo Horizonte. Mining at Pau Branco consists of hematite rich itabirite ore that is part of the iron formations within the Minas Supergroup, Quadrilátero Ferifero (Iron Quadrangle), Brazil. The Pau Branco mine produced 5.4, 7.1 and 4.1 million tonnes of iron ore in 2024, 2023 and 2022, respectively.

The mining operations were temporarily suspended in January 2022 due to flooding and damage to the Cachoeirinha waste pile. However, operations were partially restarted in May 2022. Vallourec requested the state mining and environmental authorities to release the pile fully in the fourth quarter of 2022. In May 2023, the Pau Branco iron ore mine resumed production levels after receiving permits to operate the Cachoeirinha waste pile.

Vallourec launched two projects aimed at improving the profitability and durability of the Pau Branco mine. Phase 1 was expected to be completed at the end of 2024 with a total investment of approximately €20 million. Phase 2 was scheduled for completion in 2027 and expected to cost between €100 million and €125 million. Vallourec indicated that its management was engaging with the state and national authorities to obtain the required production and environmental permits for this phase of work.

The Pau Branco mine concentrates and enriches the mined hematite ore via jigs, spirals and magnetic separators to a +60% Fe hematite product that it supplies to blast furnaces and the pellet plant of Vallourec's affiliates located at Jeceaba in Minas Gerais. The Jeceaba steel mill site is located 120 kilometers south of Belo Horizonte and consists of a premium rolling mill; a steel mill (with a blast furnace and electrical furnace), which supplies steel bars for production at the Jeceaba and Barreiro plants; a pellet unit that produces pellets used by the Jeceaba blast furnaces and the local Brazilian market; and finishing lines. The Barreiro site is an integrated unit that combines production and hot rolling equipment for the tube finishing lines. Beyond supplying Vallourec's own steel-making operation, the mine's iron ore production is also sold to external customers.

The Pau Branco mine is classified as an "exploration stage property", as that term is defined under S-K 1300, because no proven or probable mineral reserves have been determined in accordance with S-K 1300. As a result, and even though the Pau Branco mine has produced iron ore historically and is expected to continue such production, the mine will remain classified as an "exploration stage property", as that term is defined under S-K 1300, until such time as proven or probable mineral reserves have been determined and disclosed in accordance with S-K 1300. ArcelorMittal cannot guarantee that proven or probable mineral reserves will be determined and disclosed in accordance with S-K 1300 for the Pau Branco mine.

Estimates of Iron Ore Mineral Reserves and Mineral Resources

For the meanings of certain technical terms used in this annual report, see "Glossary - definitions, terminology and principal subsidiaries".

The mineral reserve and resource estimates have been prepared in accordance with S-K 1300 and Society for Mining, Metallurgy & Exploration (SME) Guide for Reporting Exploration Information, Mineral Resources, and Mineral Reserves (The "SME Guide").

The estimates of mineral resources and mineral reserves at the Company's mines and projects and the estimates of the mine life included in this report have been prepared by qualified persons, in accordance with the guidelines for mining property disclosure requirements in accordance with S-K 1300. Qualified persons are either employees of ArcelorMittal, or they are third parties or employees of a third party who are not affiliates of ArcelorMittal and neither such third parties or their employers has an ownership, royalty or other interest in the property for which they have estimated mineral reserves or mineral resources. No qualified persons have been employed on a contingent basis.

Only measured and indicated mineral resources, where the level of geological certainty associated was sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit, were converted to proven or probable mineral reserves for each of the mineral properties under the summary disclosure.

The 2024 mineral resource and mineral reserve estimates at the AMMC mining property have been prepared by qualified persons who are employees of ArcelorMittal.

The 2024 mineral resource and reserve estimates for the Las Truchas mine (consolidated as Mexico, excluding Peña Colorada in the tables below) were prepared by qualified persons of SLR Consulting (Canada) Ltd. Peña Colorada also contracted SLR Consulting (Canada) Ltd. to provide the 2024 mineral resource and reserve estimates for the Peña Colorada mine, with the support of the Peña Colorada team.

The 2024 mineral resource and reserve estimates for the Andrade and Serra Azul mines (consolidated as Brazil in the tables below) were prepared by qualified persons of the GE21 Consultoria Mineral, with the support of the ArcelorMittal Brazil local team.

The mineral resource and reserve estimates for the AMKR (Ukraine) open pit and underground operations as of December 31, 2024 were prepared by LLC "KAI" with the support of the AMKR team.

For 2024, mineral resource and reserve estimates for the Thakurani and Ghoraburhani – Sagasahi mines (India in the tables below) were prepared by a qualified person of BMRC Geomining Solutions PVT LTD.

AML's 2024 mineral resources and mineral reserves were estimated by qualified persons who are employees of ArcelorMittal.

In 2024, a qualified person of VBKOM (Pty) Ltd updated the mineral resources estimate for the Vanderbijl pit at Thabazimbi (South Africa in tables below). Estimates of mineral reserves are not reported in 2024 for ArcelorMittal South Africa iron ore operation Thabazimbi.

Mineral resources and mineral reserves as of December 31, 2024 for ArcelorMittal Prijedor (Bosnia in the tables below) were prepared by an independent qualified person.

The mineral resources and reserves for the Mary River Mine (Baffinland in the tables below) as of December 31, 2024 were calculated by annual depletion method by a qualified person from Baffinland Iron Mines based on the original estimates of a qualified person of SLR Consulting (Canada) Ltd.

The point of reference of reporting all of ArcelorMittal's mineral resources and reserves in the tables below is in situ for resources and the point of delivery of the ROM material to the processing plant for reserves. All material is reported on a wet basis and grades on a dry basis. The effective date for reporting of all mineral resources and reserves is December 31, 2024.

For each of the mining operations under the summary disclosure, economic viability of the declared mineral reserves has been determined by the qualified persons using a discounted cash flow analysis, demonstrating that extraction of the mineral reserve is economically viable under reasonable investment and market assumptions. The estimated mine life reported in this table corresponds to the duration of the production schedule of each operation based on the 2024 yearend iron ore reserve estimates only. The production varies for each operation during the mine life and as a result the mine life is not the total reserve tonnage divided by the 2024 production. Mine life of each operation is derived from the life of mine plans and corresponds to the duration of the mine production scheduled from mineral reserve estimates only. The demonstration of economic viability is established through the application of a life of mine plan for each operation or project providing a positive net present value on a cash-forward looking basis, considering the entire value chain. Economic viability is demonstrated using forecasts of operating and capital costs

based on historical performance, with forward adjustments based on planned process improvements, changes in production volumes and in fixed and variable proportions of costs, and forecasted fluctuations in costs of raw material, supplies, energy and wages. Mineral reserve estimates are updated annually in order to reflect new geological information and current mine plan and business strategies. The Company's reserve estimates are of in-place material after adjustments for mining depletion and mining losses and recoveries, with no adjustments made for metal losses due to processing. For a description of risks relating to reserves and reserve estimates, see "Introduction—Risk factors—Risks related to ArcelorMittal's mining activities".

The reported iron ore reserves contained in this report do not exceed the quantities that the Company estimates could be extracted economically if future prices were at similar levels to the average contracted price for the three years ended December 31, 2024. The Company establishes optimum design and future operating cut-off grade based on its forecast of commodity prices, adjusted for local market conditions, freight, inland logistics costs, and final product value in use premiums/ penalties, and operating and sustaining capital costs. The cut-off grade varies from operation to operation and during the life of each operation in order to optimize cash flow, return on investments and the sustainability of the mining operations. Such sustainability in turn depends on expected future operating and capital costs. Estimates of reserves and resources can vary from year to year due to the revision of mine plans in response to market and operational conditions, in particular market price. See "Introduction—Risk factors—Risks related to ArcelorMittal's mining activities—ArcelorMittal's reserve and resource estimates may materially differ from mineral quantities that it may be able to actually recover; ArcelorMittal's estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves uneconomical to mine."

To ensure that mineral resource estimates for all mines satisfy the requirements for reasonable prospects for economic extraction ("RPEE") requirement, reasonable technical and economic factors were considered by qualified persons in the process of derivation of the ultimate mineral resource pit shells or underground constraining wireframes and other spatial controls used to constrain the mineralization. Factors used are current, considered to be reasonably developed, and are based on generally accepted industry practice and experience.

Tonnage and grade estimates are reported as 'Run of Mine'. Tonnage is reported on a wet metric basis. Metallurgical recoveries are accounted for in the concentrate tonnes calculation based on historical processing data and are variable as a function of head grade.

ArcelorMittal owns less than 100% of certain mining operations; mineral reserve and mineral resource estimates have been adjusted to reflect ownership interests and therefore reflect the portion of total estimated mineral reserves and resources of each mine attributable to ArcelorMittal as per the Company's ownership interest in each mine at December 31, 2024.

The classification of the iron ore reserve estimates as proven or probable reflects the variability in the mineralization at the selected cut-off grade, the mining selectivity and the production rate and ability of the operation to blend the different ore types that may occur within each deposit.

The following table summarizes ArcelorMittal's mineral reserves as of the end of the fiscal year ended December 31, 2024 in the aggregate, and by commodity and country and for certain individual properties (each property containing 10% or more of ArcelorMittal's combined mineral reserves and certain properties containing less). Mineral reserve quantities are rounded to million tonnes. Unless indicated otherwise below, for the purpose of determining iron ore mineral reserves, ArcelorMittal has used a long-term iron ore reference price of \$70 per tonne for 62% Fe fines, based on supply/demand fundamentals and industry cost curve adjusted upwards or downwards for mine specific factors and further adjusted for grade, logistics, and other adjustments.

Cautionary note concerning mineral reserve and mineral resource estimates: With regards to ArcelorMittal's reported resources, investors are cautioned not to assume that any or all of ArcelorMittal's mineral deposits that constitute either

'measured mineral resources', 'indicated mineral resources' or 'inferred mineral resources' (estimated in accordance with S-K 1300 and the SME Guide) will ever be converted into mineral reserves. There is a reasonable level of uncertainty as to the

existence of 'inferred mineral resources' and their economic and legal feasibility, and it should not be assumed that any or all of an 'inferred mineral resource' will be upgraded to a higher category.

Internal Controls

ArcelorMittal mining and exploration properties employ robust quality control and quality assurance processes and procedures to ensure the validity and integrity of data utilized in the estimation of mineral resources and mineral reserves.

ArcelorMittal has developed an Orebody Knowledge and Management Framework, comprising a comprehensive set of internal guidelines and management standards that govern the resource and mining activities conducted at its properties. The framework and its associated documents describe the systems and processes to be developed and implemented at ArcelorMittal properties to effectively manage activities and data for the estimation and mining of its mineral resources and reserves. This framework and its associated documents are compiled and managed by a centralized corporate team of experienced and qualified technical experts and are reviewed and updated on a regular basis.

To increase rigor over internal controls and ensure integrity of its reported mineral resource and mineral reserve disclosures ArcelorMittal implements K2fly's Mineral Resource Governance and Model Manager platforms globally. This has enabled enhanced control over the consolidation of the Company's mineral resource and reserves disclosures. The K2fly solutions were deployed in 2024 after a successful implementation and configuration into the ArcelorMittal global mining portfolio and are being used in conjunction with SK-1300 Reports.

Databases are compiled and managed by experienced personnel engaged directly by the operating entities and business units, following documented procedures. Sample data derived from activities such as, but not limited to, exploration drilling and field sampling, is subject to thorough sample security and integrity protocols, field and laboratory quality assurance and quality control processes, and data validation procedures.

Field quality control processes and procedures will vary based on the specific nature of the drilling or sampling program, but will nominally include the use of duplicate samples, blank control samples and certified reference materials. Samples processed and analyzed at internal and external laboratories are subject to additional laboratory quality control processes including, but not limited to, duplicate samples and certified reference materials. Data verification workflows are employed for each program to ensure the quality and integrity of all data incorporated into the databases.

Historical data is subject to rigorous verification processes prior to inclusion in resource estimation databases. These procedures can include, but are not limited to, external database validation by independent parties, internal database audits, and spatial and statistical analyses. Where historical data cannot be verified to the satisfaction of the relevant qualified person, it is excluded from the databases used in the estimation processes.

Where applicable, all mineral resource and mineral reserve estimates are reconciled against mine production data and operational results. Geological interpretations and estimation parameters are updated, and modifying factors, cost and price assumptions validated and adjusted.

There are inherent risks associated with all mineral resource and mineral reserve estimations see "Introduction—Risk Factors —Risks associated with ArcelorMittal's Mining Activities".

OPERATING AND FINANCIAL REVIEW

Key factors affecting results of operations

Overview

The steel industry, and the iron ore and coal mining industries, which provide its principal raw materials, have historically been highly cyclical. They are significantly affected by general economic conditions, consumption trends as well as by worldwide production capacity and fluctuations in international steel trade and tariffs. This is due to the cyclical nature of the automotive, construction, machinery and equipment and transportation industries that are the principal consumers of steel.

In 2022, the global economy was adversely affected by supply chain issues, high inflation, consequential tightening of monetary policy and Russia's invasion of Ukraine (itself aggravating inflationary pressures, particularly in the energy sector). All these shocks weighed on growth in ArcelorMittal's core developed markets (EU, U.S.), with a negative impact on steel demand and pricing. During 2023 and 2024, real steel demand broadly stabilized at low levels in the core developed markets with apparent demand supported somewhat by an end to the destocking seen in 2022. The lagged impact of monetary tightening and weak real steel demand weighed on prices in the core developed markets during the second half of 2023 and through 2024, negatively impacting ArcelorMittal's profitability.

While the economy and underlying real demand was stronger in the U.S. relative to Europe during 2024, supported by continued growth in consumer expenditure, the lagged impact of tighter credit conditions and elevated interest rates negatively impacted output of interest rate sensitive sectors (e.g., machinery and residential construction), causing real steel demand to remain subdued. The European market heavily impacts the Company's prospects and economic growth has stagnated over the past 18 months Although, the European Central Bank has cut the deposit interest rate, as inflation has fallen the lagged impact of prior elevated interest rates has negatively affected the manufacturing and construction sectors that drive steel demand, with new orders and backlogs weakening and real steel demand declining during the second half of 2023 and through 2024. In addition, the recently announced imposition of tariffs on all steel imports into the U.S. could result in retaliatory protectionist measures by other countries and have a significant negative impact on global trade and economic growth. In Europe, this could potentially offset the positive impact of monetary policy easing in the region and increase the risk of an economic downturn. The automotive industry, which is a significant consumer of steel, is likely to be negatively impacted by the tariffs and resulting higher steel prices. More generally, tariffs may result in renewed inflationary pressures in the U.S. Tariffs on EU exports to the U.S. is also expected to negatively impact steel demand in EU as steel intensive manufactured goods account for a significant proportion of the EU's goods trade surplus with the U.S. U.S. tariffs are also expected to

have an effect on supply and prices in the U.S. and the Company's other markets (such as Canada and Mexico). See "Introduction—Risk Factors and Control—Unfair trade practices, import tariffs and/or barriers to free trade could negatively affect steel prices and ArcelorMittal's results of operations in various markets".

While steel demand in both the U.S. and EU continues to be well below pre-pandemic levels, steel consumption has been expected to be supported over the next few years by the American Jobs Plan ("AJP") and the Inflation Reduction Act ("IRA") in the U.S. and by the Next Generation EU ("NGEU") stimulus plans in the EU. However, beyond the impact of tariffs mentioned above, the new U.S. administration's policies present a significant downside risk to the additional steel demand from the IRA, with some potential offset from hot rolled substrate for additional pipe and tube demand from the oil sector.

Demand in some markets, such as Brazil rebounded during 2024, to well above pre-pandemic levels. Inflation has accelerated in such markets, however, driven by resilient domestic demand and by looser fiscal policy. With inflation above target, interest rates have been raised and further monetary tightening is expected, negatively impacting household consumption in 2025, which is expected to lead to broadly stable steel demand in Brazil. While many emerging markets are better placed to deal with crises than in the past, economic risks remained high through 2024 for many countries, including external foreign currency debt risk in Turkey and Argentina. This has led the Turkish lira to depreciate significantly against the U.S. dollar, causing inflationary pressure to re-accelerate and forcing the central bank to increase interest rates to over 40%, causing a downturn in the economy and stagnating steel demand in 2024.

Historically, demand dynamics in China have also substantially affected the global steel business, mainly due to significant changes in net steel exports. Continued weakness of Chinese steel demand, coupled with ample domestic supply has seen net Chinese finished flat steel exports increase from 3.4 million tonnes per month during 2022, to 5.2 million per month during 2023, 6.1 million tonnes per month during the first half of 2024 and reaching record highs of 6.6 million tonnes per month during the second half of 2024. In 2024, weak steel demand was seen in the continued decline in housing sales in China, reflecting low household confidence and with new housing starts continuing to fall during 2024. The short-term outlook for China remains largely dependent upon the timing and scale of the cyclical rebound in the real estate market, the negative impact of increased U.S. tariffs and the amount of government stimulus. While the expectation is that further government stimulus will support GDP growth in 2025, Chinese overcapacity and a need to export is expected to remain across most industries. Moreover, the Company continues to expect Chinese steel demand to decline in the medium-term, as infrastructure spending has been frontloaded and real estate demand is expected to weaken structurally due to lower levels of rural-urban migration. If the expected decline in demand does not coincide with renewed capacity closures, this could lead to steel exports from China remaining at or above current peak levels and have a negative impact on global steel prices and spreads.

Unlike many commodities, steel is not completely fungible due to wide differences in its shape, chemical composition, quality, specifications and application, all of which affect sales prices. Accordingly, there is still limited exchange trading and uniform pricing of steel, whereas there is increased trading of steel raw materials, particularly iron ore. Commodity spot prices can vary, which causes sales prices from exports to fluctuate as a function of the worldwide balance of supply and demand at the time sales are made.

ArcelorMittal's sales are made based on shorter-term purchase orders as well as some longer-term contracts to certain industrial customers, particularly in the automotive industry. Steel price surcharges are often implemented on steel sold pursuant to long-term contracts to recover increases in input costs. However, longer term contracts with low steel prices will not reflect increases in spot steel prices that occur after contract negotiation; similarly low contract prices (if contract pricing is renegotiated when steel prices are low, for example, steel contracts that reset annually) will continue to affect results even as spot steel prices increase. Spot market steel, iron ore and coal prices and short-term contracts are more driven by market conditions.

One of the principal factors affecting the Company's operating profitability is the relationship between raw material prices and steel selling prices. Profitability depends in part on the extent to which steel selling prices exceed raw material prices, and specifically the extent to which changes in raw material prices are passed through to customers in steel selling prices. Complicating factors include the extent of the time lag between (a) the raw material price change and the steel selling price change and (b) the date of the raw material purchase and of the actual sale of the steel product in which the raw material was used (average cost basis). In recent periods, steel selling prices have not always been correlated with changes in raw material prices, although steel selling prices may also be impacted quickly due in part to the tendency of distributors to increase purchases of steel products early in a rising cycle of raw material prices and to hold back from purchasing as raw material prices decline. With respect to (b), as average cost basis is used to determine the cost of the raw materials incorporated, inventories must first be worked through before a decrease in raw material prices translates into decreased operating costs. In some of ArcelorMittal's segments, in particular Europe and North America, there are several months between raw material purchases and sales of steel products incorporating those materials. Although this lag has been reduced in recent years by changes to the timing of pricing adjustments in iron ore contracts, it cannot be eliminated and exposes these

segments' margins to changes in steel selling prices in the interim (known as a "price-cost squeeze"). This lag can result in inventory write-downs, as occurred in 2022 due to sharp declines in steel prices. In addition, decreases in steel prices may outstrip decreases in raw material costs in absolute terms, as has occurred numerous times in the past. Steel spreads, especially in Europe, were compressed by elevated energy prices, particularly gas, and destocking at stockers and end-users through the second half of 2022, adversely impacting the Company's deliveries and profitability. Steel prices declined faster than raw material prices in both the third and fourth quarters of 2022, with significant compression of spreads. However, the fourth quarter of 2022 was the peak of the destocking cycle and inventory levels across ArcelorMittal's main markets fell to low levels. As destocking began to end during the first quarter of 2023, apparent demand improved from the lows of the fourth quarter of 2022 and led to a recovery in steel prices and spreads. However, with economic growth weakening across the Company's core developed markets, due to the lagged impact of interest rate rises, elevated steel prices and spreads unwound during the second and third quarters of 2023, thus negatively impacting the results of the third and fourth quarters of 2023, due to the significant lag between transactions and deliveries, especially for flat products. Prices and spreads in the Company's core markets remained relatively weak through 2024, as apparent steel demand stabilized at historically low levels in both Europe and the U.S.

Volatility on steel margins aside, the results of the Company's Mining segment (which sells externally as well as internally) are directly impacted by iron ore prices. See "—Raw materials —Iron ore". The Company believes current prices are unsustainable over the medium term, if as expected, Chinese steel demand weakens further, which would lead to further falls in iron ore prices and negatively impact ArcelorMittal's revenues and profitability. See also "Introduction—Risk factors and control—Risks related to the global economy and the mining and steel industry—Prolonged low steel and (to a lesser extent) iron ore prices, low steel demand and/or steel/ iron ore oversupply would have an adverse effect on ArcelorMittal's results of operations."

Economic environment

The global economy has undergone several years of negative shocks, starting from COVID-19's disruption in 2020-21, followed by subsequent high inflation, exacerbated by the Russian invasion of Ukraine in 2022, and to curb inflation, a sharp rise in interest rates occurred through 2023, particularly in developed economies. As a result, global GDP growth slowed to 2.8% in 2023, from 3.3% in 2022 and 6.5% in 2021. During 2024, global growth remained stable, yet subdued. Inflation continued to wane globally, making progress toward central bank targets, even though price pressures persisted in some developed countries during the first half of 2024, mainly due to elevated services inflation. Global disinflation was also supported by easing in labor market tightness during postpandemic recovery, which contained pressure from wage

inflation. The return of inflation to near central bank targets could pave the way for easing monetary policy as a result. Since June 2024, major central banks in advanced economies have started to cut their policy rates, moving their policy stance toward neutral. Overall, despite a sharp and synchronized tightening of monetary policy around the world, the global economy has remained resilient to elevated interest rates throughout the disinflationary process, avoiding a global recession in 2024. While specific pockets of weakness remain, such as the industrial recession in developed economies and real estate downturn in China, other offsetting factors, including the relative strength of services and additional fiscal stimulus from the Chinese government, have helped keep economic growth relatively steady. As a result, global GDP growth only slowed marginally to 2.7% in 2024.

After slowing to 2.5% in 2022 following the post COVID-19 rebound in 2021, U.S. GDP growth picked up to 2.9% in 2023, despite higher interest rates and inflation. Overall, cautiously loosening fiscal policy coupled with resilient consumption and investment contributed to GDP growth remaining steady at approximately 2.8% in 2024. With the new U.S. administration, downside risk to growth in 2025 centers around policy uncertainty, in particular rising trade tensions with trading partners, as higher tariffs potentially add to domestic inflationary pressure, becoming a drag on GDP growth.

After EU27 GDP growth slowed to 3.5% in 2022 due to a sharp spike in energy prices, especially gas, following the Russian invasion of Ukraine, GDP growth slowed to only 0.5% year-on-year in 2023, as the economy weakened in early 2023, and inflation rose far above target levels (resulting in increased interest rates). In 2024, economic activity, though no longer weakening, stagnated at low levels due to the lagged impact of high interest rates. The weakness of the industrial sector led to EU27 GDP growth only increasing to an estimated 0.9% year-on-year in 2024. Weaker growth led to inflation moderating and allowed the ECB to start cutting interest rates in June 2024.

China's economy has remained resilient despite the ongoing property sector downturn since 2022. GDP growth of 5.2% in 2023 (as compared to 3% in 2022), was supported by fiscal stimulus for infrastructure spending, resilient private consumption and higher manufacturing exports. These trends in 2023 largely continued during 2024. With GDP growth slowing to 5% in 2024 (driven by real estate sector downturn). Despite government monetary and fiscal stimulus in the real estate sector, there is downside risk to 2025 growth from rising trade tensions with the U.S.

In Brazil, GDP growth of 3.3% in 2024 (compared to 2.9% in 2023 and 3% in 2022) was driven by strong domestic demand supported by wages growing above inflation, unemployment falling and by looser fiscal policy. Rising debt sustainability concerns toward the year-end and continued monetary policy tightening in response to inflation, will likely weigh on growth in 2025.

In India, following strong growth of 7.7% in 2023, GDP growth in 2024 grew at an estimated 6.4% year-on-year, driven by investment and supported by strong public investment, particularly in infrastructure, and resilient consumption growth. The level of public debt means public spending is unlikely to be as strong going forward, but expected robust investment growth and strong private consumption growth are expected to, support solid economic growth.

After global apparent steel consumption ("ASC") increased by over 3% in 2021, as the global economy rebounded postpandemic, ASC declined by over 2% in 2022 due to weaker demand from China caused by COVID-19 restrictions and a destocking cycle in ex-China. In 2023, global ASC increased slightly by approximately 0.2% year-on-year, with world ex-China ASC growing by 2.1% year-on-year, offsetting an almost 2% decline in China, as persistent weakness in domestic real estate sector negatively impacted steel demand. However, weakness in the real estate sector in China worsened in 2024, causing China ASC to decline further by more than 3% yearon-year. Meanwhile, despite weak real demand in ex-China, supportive real demand in emerging markets and restocking, and strong exports from China helped ex-China ASC to grow almost 2% year-on-year. Indeed, ASC in developing markets grew an estimated 4% year-on-year, supported by strong growth in India (10% year-on-year), followed by approximately 8% year-on-year growth in Brazil offsetting weaker growth elsewhere. On the other hand, ASC in developed markets is estimated to have decreased slightly by 1% in 2024, largely driven by a decline of 3% year-on-year in ASC in "Developed Asia" (including in particular Japan, South Korea and Taiwan). EU27 steel demand was broadly stable as inventory build was enough to offset weaker real demand as the industrial recession continued. ASC in the U.S. was also slightly down by approximately 0.5% year-on-year, mainly driven by long products and pipe and tube. As a result, ex-China ASC rose by almost 2% year-on-year. However, ex-China growth was not enough to offset the decline in China, leading to global ASC estimated to have decreased by approximately 1% in 2024.

Steel production

Global production declined to 1.88 billion tonnes in 2022 as compared to 2021, driven by lower production in world ex-China resulting from high energy costs and the Russian invasion of Ukraine. In China, lower production in 2022 reflected lower steel demand, which was negatively impacted by COVID-19's exacerbation of the downturn in the real estate market.

This trend in the developed market continued in 2023, but stronger production in developing ex-China notably resulted in world ex-China production being broadly stable relative to

1. Steel production in China rose by almost 1% year-onyear in 2023, leading to a surge in Chinese net steel exports (given the slight decline in domestic demand).

Overall, global steel production in 2024 decreased marginally, down almost 1% year-on-year. Steel production in world ex-China was stable, as production in developed markets fell slightly from weak levels, offset by stronger production in developing markets. Production in the Company's major markets of Canada, the EU and the U.S. was stable, albeit at weak levels, offset by declining production in developed Asia. In 2024, the situation in China was similar to 2023, with government stimulus supporting infrastructure but only partially offsetting an even sharper decline in the real estate sector. Steel production declined less than the decline in domestic demand resulting in increased Chinese net exports relative to 2023.

Trade and import competition

Europe

There has been a trend of imports growing more strongly than domestic demand in the EU since 2012. In 2022, the Russian invasion of Ukraine in February triggered an energy crisis in Europe, causing both ASC and imports to decline sharply during the second half of 2022. As a result, import penetration only rose marginally to 20% in 2022.

In 2023, while subdued demand in Europe meant both ASC and imports declined year-on-year, the decrease in imports was slightly greater than the fall in ASC, which led to import penetration declining slightly to 19%. In 2024, imports once again increased, estimated at approximately 9% year-on-year. Strong import growth coupled with relatively stable demand has pushed import penetration up to approximately 20% in 2024.

United States

Steel imports continued to increase strongly during 2022, with the increase in imports (10% year-on-year) coupled with a decline in steel demand leading to import penetration increasing to over 23%. The weakening trend in imports since late 2022 continued through 2023, with imports falling by approximately 14% year-on-year while ASC only declined by approximately 3.5% year-on-year. The much sharper decline in imports pushed import penetration down to approximately 21% in 2023. In 2024, imports stopped falling and rose by an estimated 1.6% year-on-year, while ASC (mainly long products, pipe and tube) continued to decline by

approximately 3%, leading import penetration to rise slightly to 22%.

Source: American Iron and Steel Association total/regional imports data and ASC data to November 2024, internal Company estimate for December 2024.

China

In 2022, Chinese finished steel exports were broadly stable, up only 0.8% year-on-year to 67.4 million tonnes as compared to 66.9 million tonnes in 2021. With weak demand in China and a large price gap to ex-China, Chinese finished steel exports increased strongly in 2023, to 91.2 million tonnes, an increase of approximately 25 million tonnes from 2022 levels. This trend continued in 2024, with finished steel exports rising by 22% year-on-year to 111 million tonnes for 2024. While most Chinese exports are delivered to regions which are not core to the Company's business due to the protection of trade measures, Chinese exports still negatively impact the Company both directly and indirectly. See "Business overview —Government regulations—Foreign trade" and "Introduction —Risk Factors and Control—Risks related to the global economy and the mining and steel industry—Unfair trade practices, import tariffs and/or barriers to free trade could negatively affect steel prices and ArcelorMittal's results of operations in various markets."

Steel prices

In relation to flat products, European hot rolled coil ("HRC") prices (both Northern and Southern), U.S. domestic Midwest HRC prices and Chinese HRC prices, VAT excluded, over the 2022-2024 period generally reflect a downward trend. Likewise, in relation to long products, European medium and rebar prices and Turkish rebar prices experienced a similar trend over this period. Movements in these prices over this period have been driven by a number of factors affecting demand and supply in such markets, including the effects of the war in Ukraine (started at the end of February 2022), inflation, recessionary concerns, supply chain constraints and labor shortages that weakened manufacturing and demand in certain industries (including as a result of COVID-19

restrictions), import levels and domestic mill outages (e.g., for maintenance or otherwise).

Raw materials

The primary raw material inputs for a steelmaker are iron ore, coking coal, solid fuels, metallics (e.g., scrap), alloys, electricity, natural gas and base metals. ArcelorMittal is exposed to price volatility in each of these raw materials with respect to its purchases in the spot market and under its longterm supply contracts. In the longer term, demand for raw materials is expected to continue to correlate closely with the steel market, with prices fluctuating according to supply and demand dynamics. Since most of the minerals used in the steelmaking process are finite resources, their prices may also rise in response to any perceived scarcity of remaining accessible supplies, combined with the evolution of the pipeline of new exploration projects to replace depleted resources.

As for pricing mechanisms, quarterly and monthly pricing systems are the main type of contract pricing mechanisms, but spot purchases have gained a greater share, in particular since 2020, as steelmakers have developed strategies to benefit from increasing spot market liquidity and volatility. Pricing is generally linked to market price indexes and uses a variety of mechanisms, including current spot prices and average prices over specified periods. Therefore, there may not be a direct correlation between market reference prices and actual selling prices in various regions at a given time.

Iron ore

In 2022, iron ore market reference prices decreased to an average of \$120.03/t, down by 24.9% compared to an average of \$159.89/t in 2021, mainly due to collapsing market confidence as China implemented strict lockdowns across the country starting in mid-March, boycotts from homebuyers in China resulting from failures to meet construction schedules which weighed further on the crisis-stricken real estate sector, harsh weather conditions in the summer and the US Federal Reserve's tightening of its monetary policy.

In 2023, iron ore market reference prices averaged \$119.54/t, relatively stable compared to an average of \$120.03/t in 2022. The first quarter of 2023 began with an increase in reference prices mainly driven by prevailing bolstered sentiment on scrap of COVID control in China, which was later counteracted by the disappointing actual economy recovery, largely dragged by its real estate woes and sliding exports. By the end of 2023, iron ore market reference prices increased to \$141.92/t on December 27, a record high for the period dating back to June 9, 2022, driven by lower port inventory, stimulus anticipation and strong demand outlook for Chinese economy in the first quarter of 2024, following the deposits rate cut by Chinese commercial banks on December 22, 2023.

In 2024, iron ore market reference prices dropped to an average of \$109.46/t, down by \$10.08/t compared to an average of \$119.54/t in 2023. Prices fell for the first three quarters of 2024 due to persistently sluggish demand amid economic weakness generally and a real estate slowdown specifically, but recovered slightly in the fourth quarter of 2024 on boosted sentiment from stimulus policies.

Coking coal

Coking coal prices in 2022 averaged \$364.22/t as compared to \$227.29/t in 2021, driven by faster-than-expected demand recovery, tight global supply and geopolitical tensions. Australia confronted both heavy rainfall, which affected production and logistics in Queensland, and a severe rise in COVID-19 pandemic cases. Russia's invasion of Ukraine sent prices to new records in March 2022. Prices increased in December 2022 as China neared lifting its ban on Australian coal imports.

Coking coal prices in 2023 averaged \$295.97/t as compared to \$364.22/t in 2022. Although coking coal prices decreased slightly in 2023, they still remained at a historic high at year

end. Supply disruption in Australia, caused by the wet season, port maintenance, higher vessel queues, and lower production from BHP, South 32, and Anglo due to longwall issues, coupled with strong demand from India and China, kept the prices at an elevated level. In the Chinese market, continuous mine accidents and safety checks resulted in increased domestic coking coal prices.

In 2024, coking coal prices averaged \$241.32/t as compared to \$295.97/t in 2023, driven by weak global steel demand amid increased supply due to eased weather-related disruptions starting in the third quarter of 2024, despite the fire accident in Anglo's Grosvenor mine at the end of June 2024. China reduced its coal imports from seaborne Australian supply as Australian prices lost competitiveness compared to falling Chinese domestic coking coal prices and Indian demand was muted due to weakening margins of steel mills. China and India account for almost 40% of global demand for seaborne supply, and these two countries are main participants in the global spot market.

ArcelorMittal has continued to leverage its iron ore and coking coal supply chain and diversified supply portfolio as well as the flexibility provided by contractual terms to mitigate regional supply disruptions and also mitigate part of the market price volatility.

The average index price for 2024 was €359/t as compared to €365/t in 2023, a €6/t or 2% decrease compared to 2023. The average price in 2022 was €409/t.

Turkey remains the main scrap buying country in the international market.

Scrap Index HMS 1&2 CFR Turkey, North Europe origin, started January 2024 at \$414/t and reached the yearly low of \$341/t in December 2024. Scrap Index HMS 1&2 CFR Turkey, North Europe origin, started January 2023 at \$407/t and

ended at \$415/t in December 2023 (after reaching \$357/t in October 2023).

In 2024, the average prices for European domestic scrap price of grade 3 were \$389/t. In 2023, average European domestic scrap prices of grade 3 were at \$395/t.

In the domestic U.S. market, HMS 1 delivered Midwest index decreased from an average of \$349/t in 2023 to \$330/t in 2024 and decreased from an average of \$387/t in 2022 to \$349/t in 2023. On the export market, HMS export FOB New York average prices for 2024 were at \$347/t, a decrease of \$17/t compared to 2023.

Ferro alloys and base metals

Ferro alloys

The underlying price driver for manganese alloys is ordinarily the price of manganese ore, which was at the level of \$5.53 per dry metric tonne unit ("dmtu") (for 44% lump ore) on Cost, Insurance and Freight ("CIF") China for 2024, representing a 5.93% increase from \$5.22/dmtu in 2023 (\$5.97/dmtu in 2022).

High carbon ferro manganese prices increased by 4% from \$1,244/t in 2023 to \$1,292/t in 2024 (\$2,042/t in 2022), silicon manganese increased by 6% from \$1,266/t in 2023 to \$1336/t in 2024 (\$2,123/t in 2022) and medium carbon ferro manganese prices decreased by 2% from \$1,832/t in 2023 to \$1,790/t in 2024 (\$3,332/t in 2022).

Base metals

Base metals used by ArcelorMittal are zinc, tin and aluminum for coating, aluminum for deoxidization of liquid steel and nickel for producing stainless or special steels. ArcelorMittal partially hedges its exposure to its base metal inputs in accordance with its risk management policies.

The average price of zinc for 2024 was \$2,777/t, representing a 4.8% increase as compared to the 2023 average price of \$2,649/t (the 2022 average was \$3,485/t).

The average price of tin for 2024 was \$30,191/t, 16.6% higher than the 2023 average of \$25,895/t. In 2022 average was \$31,102/t).

The average price of aluminum for 2024 was \$2,419/t, representing a 7.4% increase compared to the 2023 average of \$2,252/t (the 2022 average was \$2,707/t).

The average price of nickel for 2024 was \$16,812/t, representing a 21.7% decrease compared to the 2023 average of \$21,474/t (the 2022 average was \$25,604/t).

Energy market and CO²

Solid fuels, electricity and natural gas are some of the primary energy inputs for a steelmaker. ArcelorMittal is exposed to price volatility in each of these energy types with respect to its purchases in the spot market and under its long-term supply contracts.

Oil

Brent crude oil price averaged \$79.86/bbl in 2024, a decrease of \$2.29/bbl as compared to 2023 which averaged at \$82.15/ bbl. Brent crude oil prices in 2023 reflected a decrease of \$16.9/bbl compared to 2022, which averaged \$99.05/bbl. Brent crude oil price volatility over the 2022-2024 period has been exacerbated by a number of geopolitical and macroeconomic factors, including the war in Ukraine, conflicts in the Middle East, production decisions by Organization of Petroleum Exporting Countries ("OPEC") and other countries, embargoes on Russian oil, monetary policy (including by the U.S. Federal Reserve), economic growth or weakness and general perception over the economic outlook.

CO²

The average price for one tonne of CO2 emitted in 2024 decreased by 21.9% compared to 2023 and reached €66.5 per ton of carbon dioxide equivalent ("/tCO2e"). The average price for one tonne of CO2 emitted in 2023 increased by 4.9% compared to the previous year.

Variations in the price per ton of carbon dioxide equivalent is driven by a number of factors, including compliance buying, temperatures and natural gas prices and storage levels (impacting level of power generation from coal power plants).

Because the integrated steel process leads to substantial CO² emissions, costs related to EUAs and the fluctuations in EUA prices can significantly affect the Company's costs of production. The Company recognized a CO2 emission obligation provision of \$420 million at December 31, 2024 with respect to its shortfall. See note 9.1 to the consolidated financial statements. The Company also uses derivative financial instruments to manage its exposure to fluctuations in prices of emission rights allowances from time to time. See note 6.3 to the consolidated financial statements for further information.

Natural gas

In Europe, the overall spot price (or TTF) average for natural gas in 2024 was €34.9/MWh, a 15% decrease in comparison to previous year. In 2023, natural gas prices averaged at €40.9/MWh, a 66% decrease in comparison to 2022. TTF prices over the 2022-2024 have been impacted by a number of factors, including the invasion of Ukraine (and the German government's decision not to proceed with the Russianbacked Nord Stream 2 project) and other geopolitical tensions and conflicts (e.g., in the Middle East), imports of liquefied natural gas ("LNG") (e.g., from the U.S.), temperatures, maintenance of pipelines, inventory levels, coal prices. Russian transit gas into Europe ceased at the end of 2024, which is expected to have an impact on 2025.

In the U.S., Henry Hub ("HH", the main gas hub in Louisiana) prices in 2024 dropped to an average of \$2.4/MMBtu, a 10% year-on-year decrease as compared to \$2.7/MMBtu in 2023. In 2023, HH average natural gas prices fell to \$2.7/MMBtu, a 59% decrease compared to 2022. HH prices over the 2022-2024 have been impacted by a number of factors, including disruptions in gas production (e.g., from severe weather events or fires), increased LNG production capacity, demand for LNG exports (including from Europe), inventory levels and temperatures.

In 2024, the Japan Korea Marker ("JKM", the LNG benchmark price assessment for spot physical cargoes delivered ex-ship into Japan, South Korea, China and Taiwan) average price dropped to \$11.9/MMBtu, a 17% decrease compared to 2023. The JKM average price of \$14.4/MMBtu in 2023 represented a 58% decrease compared to 2022. JKM prices over the 2022-2024 have been impacted by a number of factors, including the invasion of Ukraine and other geopolitical tensions (e.g., Middle East), temperatures, ability to switch to oil and domestic gas consumption, Chinese demand (suppressed by COVID-19 outbreaks), inventory levels, demand from outside of Asia (e.g., Europe), LNG supply from

outside of Asia (e.g., U.S.), adverse weather events (e.g., cyclones) and outages at production facilities.

Electricity - Europe

Due to the regional nature of electricity markets, prices follow mainly local drivers (i.e., energy mix of the respective country, power generation from renewables such as nuclear, country specific energy policies, etc.), as well as temperatures and natural gas prices (positively correlated).

In 2022, electricity prices reached new highs amid high natural gas prices.

In 2023 power prices mainly followed the same trend as natural gas prices.

In 2024, European power demand remained at the lower end of the 7-year range due to mild weather and availability of power generation from renewables.

The following table shows quarterly average spot prices of electricity in Germany, France and Belgium for the past three years:

Ocean freight

Transportation costs, particularly shipping, constitute a principal input cost. Shipping freight rates vary depending on several factors, such as demand (including from China), positional tonnage deficits relative to demand in both the Atlantic and Pacific basins, weather conditions, water levels in the Panama Canal and fleet growth. Moreover, the relatively new ETS regulations that entered into force at the start of 2024 continue to have an impact on the market as average vessel speeds dropped to comply with the stricter environmental requirements and to limit costs.

The Baltic Dry Index ("BDI") (an index of average prices paid for transport of dry bulk materials) average was at 1,378 points in 2023 compared to 1,934 points in 2022. The Capesize sub-index (cargoes of about 150,000 tonnes) increased by 1.31% year-on-year to an average of \$16,389/ day in 2023 compared to \$16,177/day in 2022. The Panamax sub-index (cargoes of about 60-70,000 tonnes) decreased by 38.01% to an average of \$12,854/day as compared to \$20,736/day in 2022. In 2023, the Supramax sub-index (cargoes of about 48-60,000 tonnes) fell to an average of \$11,240/day as compared to \$22,152/day in 2022, a 49.26% decline.

The BDI average was at 1,755 points in 2024 compared to 1,378 points in 2023. The Capesize index increased by 37.8% year-on-year to an average of \$22,592/day in 2024 compared to \$16,389/day in 2023. The Panamax index increased by 9.7% to an average of \$14,099/day as compared to \$12,854/ day in 2023. In 2024, the Supramax index increased to an average of \$13,600/day as compared to \$11,240/day in 2023, a 21% increase.

Impact of exchange rate movements

Because a substantial portion of ArcelorMittal's assets, liabilities, sales and earnings are denominated in currencies other than the U.S. dollar (its reporting currency), ArcelorMittal has exposure to fluctuations in the values of these currencies

relative to the U.S. dollar. These currency fluctuations, especially the fluctuation of the U.S. dollar relative to the euro, as well as fluctuations in the currencies of the other countries in which ArcelorMittal has significant operations and sales, can have a material impact on its results of operations. For example, ArcelorMittal's subsidiaries may purchase raw materials, including iron ore and coking coal, in U.S. dollars, but may sell finished steel products in other currencies. Consequently, an appreciation of the U.S. dollar will increase the cost of raw materials; thereby having a negative impact on the Company's operating margins, unless the Company is able to pass along the higher cost in the form of higher selling prices. In order to minimize its currency exposure, ArcelorMittal enters into hedging transactions to lock-in a set exchange rate, as per its risk management policies.

Since April 1, 2018, the Company has designated a portfolio of euro denominated debt (€4.1 billion as of December 31, 2024) as a hedge of certain euro denominated investments (€8.2 billion as of December 31, 2024) in order to mitigate the foreign currency risk arising from certain euro denominated subsidiaries net assets. The risk arises from the fluctuation in spot exchange rates between the euro and U.S. dollar, which causes the amount of the net investments to vary. See also note 6.3 to the consolidated financial statements. As a result of the hedge designation, foreign exchange gains and losses related to the portfolio of euro denominated debt are recognized in other comprehensive income.

As of December 31, 2024, the Company is mainly subject to foreign exchange exposure relating to the euro, Brazilian real, Canadian dollar, Indian rupee, South African rand, Mexican peso, Polish zloty, Argentinian peso and Ukrainian hryvnia against the U.S. dollar resulting from its payables, receivables or foreign operations denominated in such currencies.

Critical accounting policies and use of judgments and estimates

Management's discussion and analysis of ArcelorMittal's operational results and financial condition is based on ArcelorMittal's consolidated financial statements, which have been prepared in accordance with IFRS. The preparation of financial statements in conformity with IFRS recognition and measurement principles and, in particular, making the critical accounting judgments highlighted below require the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Management reviews its estimates on an ongoing basis using currently available information. Changes in facts and circumstances or obtaining new information or more experience may result in revised estimates, and actual results could differ from those estimates.

An overview of ArcelorMittal's critical accounting policies under which significant judgments, estimates and assumptions are made may be found in note 1.3 to the consolidated financial statements.

Legal proceedings

ArcelorMittal is currently and may in the future be involved in litigation, arbitration or other legal proceedings. Provisions related to legal and arbitration proceedings are recorded in accordance with the accounting policies described in note 9.1 to ArcelorMittal's consolidated financial statements. Please refer to note 9.3 for a description of contingencies, including legal proceedings.

Operating results

The following discussion and analysis should be read in conjunction with ArcelorMittal's consolidated financial statements included in this annual report.

As from January 1, 2024, ArcelorMittal implemented changes to its organizational structure. India and joint ventures are presented as a new operating segment including the joint ventures AMNS India, VAMA and AMNS Calvert as well as all other associates, joint ventures ("JVs") and other investments; the results of these entities are included in the line "Investments in associates, joint ventures and other investments" and discussed in such section. The segment Sustainable Solutions is composed of a number of niche, capital light businesses playing an important role in supporting climate action (including renewables, special projects and construction business), which were previously reported within the Europe segment and are now reported as a separate operating segment. The NAFTA segment has been renamed North America. Finally, following the sale of the Company's operations in Kazakhstan, the remaining operations of the former ACIS segment, i.e. ArcelorMittal Kryvyi Rih and ArcelorMittal South Africa, were assigned to Others. Segment disclosures have been recast to reflect this new segmentation in conformity with IFRS.

ArcelorMittal reports its operations in six reportable segments: North America, Brazil, Europe, India and JVs, Sustainable Solutions and Mining, with the remainder of its operations in "Others". The key performance indicators that ArcelorMittal's management uses to analyze operations are sales, average steel selling prices, crude steel production, steel shipments, iron ore production and operating income. Management's analysis of liquidity and capital resources is driven by net cash flow from operations and capital expenditures.

Sales

ArcelorMittal had sales of \$62.4 billion for the year ended December 31, 2024, representing an 8.5% decrease from sales of \$68.3 billion for the year ended December 31, 2023, primarily due to 7.6% lower average steel selling prices and a 2.4% decline in steel shipments. In the first half of 2024, sales decreased by 12.3% to \$32.5 billion from \$37.1 billion for the first half of 2023, primarily due to 4.6% lower steel shipments and 7.5% lower average steel selling prices. In the second half of 2024, sales decreased by 4.0% to \$29.9 billion from \$31.2 billion for the second half of 2023, primarily due to 7.5% lower average steel selling prices.

ArcelorMittal had sales of \$68.3 billion for the year ended December 31, 2023, representing a 14.5% decrease from sales of \$79.8 billion for the year ended December 31, 2022, primarily due to 13.5% lower average steel selling prices. In the first half of 2023, sales were \$37.1 billion, decreasing from \$44.0 billion in the first half of 2022, primarily due to lower steel shipments and 15% lower average steel selling prices. In the second half of 2023, sales of \$31.2 billion represented a 13.1% decrease as compared to sales of \$35.9 billion in the second half of 2022, primarily driven by an 11.8% decrease in average steel selling prices, a negative currency translation impact offset in part by 2.9% higher steel shipments.

Export sales

Because Group's customers and operations are mainly based outside its home country of Luxembourg, all of its sales are considered to be export sales. Annual sales to a single individual customer did not exceed 5% of sales in any of the periods presented.

Cost of sales

Cost of sales consists primarily of purchases of raw materials necessary for steel-making (iron ore, coke and coking coal, scrap and alloys), energy, repair and maintenance costs, as well as direct labor costs, depreciation and impairment. Cost of sales for the year ended December 31, 2024 was \$56.7 billion as compared to \$63.5 billion for the year ended December 31, 2023, mainly driven by lower iron ore, coal and energy costs (see below for more details). Cost of sales for the year ended December 31, 2024 included \$116 million impairment charges of property, plant and equipment, of which \$37 million related to the announced wind down of the Longs Business in ArcelorMittal South Africa, \$43 million relating to write off of certain civil works following the termination of the Monlevade expansion project in Brazil and \$36 million in connection with the closure of the Kraków coke plant in Poland. Cost of sales for the year ended December 31, 2024 also included \$216 million of restructuring charges, including \$74 million relating to the Europe segment, \$79 million relating to Sustainable Solutions and \$63 million related to the announced wind down of the Longs Business in ArcelorMittal South Africa. Cost of sales for the year ended December 31, 2023 included \$1.5 billion foreign exchange translation losses and impairment charges of \$0.9 billion in connection with the sale of ArcelorMittal's Kazakhstan operations, the Company's steel and mining operations in Kazakhstan, of which \$0.7 billion impairment of property, plant and equipment and \$0.2 billion impairment of former ACIS goodwill.

These shipments, which vary between periods due to slab sourcing mix and timing of vessels in a period, amounted to 1,867,000 tonnes, 1,660,000 tonnes and 1,173,000 tonnes in 2024, 2023 and 2022, respectively.

Crude steel production, steel shipments and average steel selling price

Crude steel production for the North America segment decreased by 13.6% to 7.5 million tonnes for the year ended December 31, 2024 as compared to 8.7 million tonnes for the year ended December 31, 2023. Crude steel production in the North America segment decreased 9.4% to 4.0 million tonnes in the first half of 2024 as compared to 4.4 million tonnes for the first half of 2023 and decreased 17.9% to 3.5 million tonnes in the second half of 2024 as compared to 4.3 million tonnes in the second half of 2023. This resulted mainly from the illegal blockade of Mexico's steel plant in Lazaro Cardenas and mine located in the Tenencia La Mira in the state of Michoacán by a group of workers due to their dissatisfaction with the distribution of profit sharing by the Company during the second and third quarters of 2024. In order to maintain safety within and outside the plant, the Company halted the steel and mining operations, and undertook mitigation actions to continue to serve customers. The estimated impact was approximately 800,000 tonnes of foregone steel production and lost operating income of \$0.2 billion (including increased costs due to the actions mentioned above). On July 19, 2024, the Company announced that it approved a new settlement with unions with an agreement to end the strike and blockade leading to a gradual restart of crude steel production, which continued to normalize during the fourth quarter of 2024 and is expected to fully recover in the first quarter of 2025.

Income tax expense (benefit)

ArcelorMittal recorded an income tax expense of \$1.5 billion for the year ended December 31, 2024 as compared to \$0.2 billion for the year ended December 31, 2023. The increase included a \$0.4 billion decrease in deferred tax asset and resulting deferred tax expense related to the decrease of the statutory tax rate in Luxembourg effective January 1, 2025 from 24.94% to 23.87%. Income tax expense included also in 2024 a \$0.2 billion provision relating to expected resolution of the tax disputes in the North America segment. See note 10.1 to the consolidated financial statements.

ArcelorMittal recorded an income tax expense of \$0.2 billion for the year ended December 31, 2023 as compared to \$1.7 billion for the year ended December 31, 2022 reflecting overall lower taxable income.

ArcelorMittal's consolidated income tax expense (benefit) is affected by the income tax laws and regulations in effect in the various countries in which it operates and the pre-tax results of its subsidiaries in each of these countries, which can change from year to year. ArcelorMittal operates in

jurisdictions, mainly in Eastern Europe and Asia, which have a structurally lower corporate income tax rate than the statutory tax rate as enacted in Luxembourg (23.87%), as well as in

jurisdictions, mainly in Brazil and Mexico, which have a structurally higher corporate income tax rate.

The statutory income tax expense (benefit) and the statutory income tax rates of the countries that most significantly resulted in the tax expense (benefit) at statutory rate for each of the years ended December 31, 2024, 2023 and 2022 are as set forth below:

Non-controlling interests

Net income attributable to non-controlling interests was \$41 million, \$103 million and \$236 million for the years ended December 31, 2024, 2023 and 2022, respectively. Net income attributable to non-controlling interests decreased in 2024 compared to 2023 and 2022 primarily as a result of lower operating performance.

Net income attributable to equity holders of the parent

ArcelorMittal's net income attributable to equity holders of the parent was \$1.3 billion, \$0.9 billion and \$9.3 billion for the years ended December 31, 2024, 2023 and 2022, respectively.

Liquidity and capital resources

ArcelorMittal's principal sources of liquidity are cash generated from its operations and its credit facilities at the corporate level.

Because ArcelorMittal is a holding company, it is dependent upon the earnings and cash flows of, as well as dividends and distributions from, its operating subsidiaries to pay expenses and meet its debt service obligations. Cash and cash equivalents are primarily centralized at the parent level and are managed by ArcelorMittal Treasury SNC, although from time to time cash or cash equivalent balances may be held at the Company's international subsidiaries or its holding companies. Some of these operating subsidiaries have debt

outstanding or are subject to acquisition agreements that impose restrictions on such operating subsidiaries' ability to pay dividends, but such restrictions are not significant in the context of ArcelorMittal's overall liquidity. Repatriation of funds from operating subsidiaries may also be affected by tax and foreign exchange policies in place from time to time in the various countries where the Company operates, though none of these policies is currently significant in the context of ArcelorMittal's overall liquidity.

In management's opinion, ArcelorMittal's credit facilities and working capital are adequate for its present requirements.

As of December 31, 2024, ArcelorMittal's cash and cash equivalents and restricted cash amounted to \$6.5 billion (including restricted cash of \$84 million, of which \$68 million relating to various environmental obligations, true sales of receivables programs and letter of credits issued in ArcelorMittal South Africa) as compared to \$7.8 billion (including restricted cash of \$97 million, of which \$54 million relating to various environmental obligations and true sales of receivables programs in ArcelorMittal South Africa) as of December 31, 2023. In addition, ArcelorMittal had available borrowing capacity of \$5.5 billion under its \$5.5 billion revolving credit facility as of December 31, 2024 compared to \$5.4 billion as of December 31, 2023. For information on the

currencies of cash and cash equivalents and restricted cash, see note 6.1.4 to the consolidated financial statements.

As of December 31, 2024, ArcelorMittal's total debt, which includes long-term debt and short-term debt was \$11.6 billion, compared to \$10.7 billion as of December 31, 2023.

Net debt (defined as long-term debt (\$8.8 billion) plus shortterm debt (\$2.7 billion), less cash and cash equivalents, restricted cash and other restricted funds (\$6.5 billion)) was \$5.1 billion as of December 31, 2024, up from \$2.9 billion at December 31, 2023 (long-term debt of \$8.4 billion plus shortterm debt of \$2.3 billion, less cash and cash equivalents and restricted cash of \$7.8 billion). Most of the external debt is borrowed by the parent company on an unsecured basis and bears interest at varying levels based on a combination of fixed and variable interest rates. Gearing (defined as net debt divided by total equity) at December 31, 2024 and 2023 was 10% and 5%, respectively. See note 6.3 to the consolidated financial statements.

The margin applicable to ArcelorMittal's principal credit facilities (\$5.5 billion revolving credit facility and certain other credit facilities) and the coupons on certain of its outstanding bonds are subject to adjustment in the event of a change in its long-term credit ratings. On June 16, 2023, Standard & Poor's upgraded its outlook on ArcelorMittal to positive on expected strengthening of the business and affirmed the 'BBB-' investment grade rating. On February 19, 2024, Moody's revised its outlook on ArcelorMittal to 'Positive' from 'Stable' on expected strengthening of its business profile and structurally improving its profitability, and affirmed the 'Baa3' investment grade rating. See "Introduction—Risk Factors and Controls— Risks related to ArcelorMittal's financial position and organizational structure—ArcelorMittal's indebtedness could have an adverse impact on its results of operations and financial position, and the market's perception of ArcelorMittal's leverage may affect its share price."

ArcelorMittal's \$5.5 billion revolving credit facility (see "— Financings—Principal credit facilities" below) contains restrictive covenants, which among other things, limit encumbrances on the assets of ArcelorMittal and its subsidiaries, the ability of ArcelorMittal's subsidiaries to incur debt and the ability of ArcelorMittal and its subsidiaries to dispose of assets in certain circumstances.

Non-compliance with the covenants in the Company's borrowing agreements entitles the lenders under such facilities to accelerate the Company's repayment obligations. The Company was in compliance with the financial covenants in the agreements related to all of its borrowings as of December 31, 2024.

As of December 31, 2024, ArcelorMittal had guaranteed \$375 million of debt of its operating subsidiaries compared to \$234 million as of December 31, 2023. See also note 9.4 to the consolidated financial statements for a description of guarantees by ArcelorMittal for joint ventures indebtedness of \$6.3 billion as of December 31, 2024 including \$4.0 billion issued on behalf of AMNS India, \$1.2 billion issued on behalf of Calvert, \$303 million in relation to outstanding lease liabilities for vessels operated by Global Chartering, \$183 million on behalf of Ventos de Santos Antonio and \$186 million on behalf of Al Jubail. ArcelorMittal's debt facilities have provisions whereby the acceleration of the debt of another borrower within the ArcelorMittal group could, under certain circumstances, lead to acceleration under such facilities.

In particular, with respect to joint ventures, on March 16, 2020, the parent company of AMNS India entered into a \$5.1 billion ten-year term loan agreement with Japan Bank for International Cooperation ("JBIC"), MUFG Bank LTD., Sumitomo Mitsui Banking Corporation, Mizuho Bank Europe N.V., and Sumitomo Mitsui Trust Bank, Limited (London Branch) in connection with the acquisition of AMNS India. The obligations under the term loan agreements are both guaranteed by ArcelorMittal and NSC in proportion to their interests in the joint venture, 60% and 40%. On April 28, 2021, the syndicate of Japanese banks amended the agreement and agreed that the Leverage Ratio financial covenant would fall away in the event that the Company obtains an investment grade long-term credit rating (with a stable outlook) from two rating agencies (which occurred in 2021).

On March 30, 2023, AMNS Luxembourg entered into an additional \$5 billion loan agreement ("JBIC co-financing loan") with the same syndicate of Japanese banks. As for the abovementioned loan, the obligations of AMNS Luxembourg under the term loan agreement are guaranteed by ArcelorMittal and NSC in proportion to their interests in the joint venture, 60% and 40%, respectively. The proceeds obtained through the JBIC co-financing loan are being used to finance the expansion of AMNS India's steelmaking capacity at its Hazira plant from 8.6 million tonnes to 15 million tonnes. In addition to the primary steelmaking capacity expansion, the project includes the development of downstream rolling and finishing facilities that will enhance AMNS India's ability to produce value-added steels for sectors including defense, automotive and infrastructure.

The following table summarizes the repayment schedule of ArcelorMittal's outstanding indebtedness, which includes short-term and long-term debt, as of December 31, 2024.

Further information regarding ArcelorMittal's outstanding shortterm and long-term indebtedness as of December 31, 2024, including the breakdown between fixed rate and variable rate debt, is set forth in note 6 to the consolidated financial statements. Further information regarding ArcelorMittal's use of financial instruments for hedging purposes is set forth in note 6 to the consolidated financial statements.

Financings

ArcelorMittal's principal credit facilities are described below, for further information on its existing credit facilities and several debt financing and repayment transactions completed during 2024, please refer to note 6 to the consolidated financial statements.

Principal credit facilities

On May 29, 2024, ArcelorMittal signed a new \$5.5 billion revolving credit facility (the "Facility") which replaced the \$5.5 billion revolving credit facility dated December 19, 2018 (amended on April 27, 2021) to incorporate a single tranche of \$5.5 billion maturing on May 29, 2029, with two one-year extension options at the lenders' discretion (i.e., the options to extend are to be exercised before the dates that are respectively one and two years after the signing date of the agreement). The Facility may be used for general corporate purposes and was fully available as of December 31, 2024.

On September 30, 2010, ArcelorMittal entered into a \$500 million revolving multi-currency letter of credit facility (the "Letter of Credit Facility"). The Letter of Credit Facility is used by the Company and its subsidiaries for the issuance of letters of credit and other instruments. The terms of the letters of credit and other instruments contain certain restrictions as to duration. The Letter of Credit Facility, whose amount and maturity have been revised from time to time, amounted to \$395 million. On July 31, 2024, the Company refinanced its Letter of Credit Facility by entering into a \$445 million revolving multi-currency letter of credit facility, which extended the maturity from July 31, 2024 to July 31, 2027, with two oneyear extension options.

Mandatory convertible bond

On March 14, 2023, the Company through its wholly-owned subsidiary Hera Ermac made an early repayment of 226,666 of the 666,666 outstanding unsecured and unsubordinated bonds mandatorily convertible into preferred shares of such

subsidiary for a total cash consideration of \$340 million. See notes 11.2 and 11.2 to the consolidated financial statements. On December 21, 2023, the Company extended the conversion date of its bonds mandatorily convertible into preferred shares to January 30, 2026.

Working capital management

The Company makes drawdowns from and repayments on the Facility in the framework of its cash management. In addition, the Company has established a number of programs for sales without recourse of trade accounts receivable to various financial institutions (referred to as true sale of receivables ("TSR")). As of December 31, 2024, the total amount of trade accounts receivables sold amounted to \$4.4 billion. Through the TSR programs, certain operating subsidiaries of ArcelorMittal surrender the control, risks and benefits associated with the accounts receivable sold; therefore, the amount of receivables sold is recorded as a sale of financial assets and the balances are removed from the consolidated statements of financial position at the moment of sale.

As part of the Company's ongoing efforts to improve its working capital position, it continually engages with its customers and suppliers with the aim of improving overall terms, including pricing, quality, just in time delivery, discounts and payment terms. Trade accounts payable have maturities from 15 to 180 days depending on the type of material, the geographic area in which the purchase transaction occurs and the various contractual agreements. The Company's average outstanding number of trade payable days amounted to 83 over the last 5 years. The ability of suppliers to provide payment terms may be dependent on their ability to obtain funding for their own working capital needs and or their ability to early discount their receivables at their own discretion (the Company estimates that about \$2.8 billion of trade payables were subject to early discount by its suppliers in 2024 as compared to \$2.9 billion in 2023). Given the nature and large diversification of its supplier base the Company does not expect any material impact to its own liquidity position as a result of suppliers not having access to liquidity. As of December 31, 2024, a 5-day reduction in trade payable days would result in a trade payables decrease by \$632 million.

ArcelorMittal's material cash requirements in the near and medium term

The Company's cash requirements in the near and medium term are primarily driven by the current commitments, obligations and other arrangements in place as of December 31, 2024. ArcelorMittal has various purchase commitments for materials, supplies and capital expenditure incidental to the

ordinary course of business. As of December 31, 2024, ArcelorMittal had various outstanding obligations mostly related to:

• Guarantees, pledges and other collateral related to financial debt and credit lines given on behalf of third parties and joint ventures,
• Capital expenditure commitments mainly related to commitments associated with investments in expansion and improvement projects by various subsidiaries,
• Other commitments comprising mainly commitments incurred for gas supply to electricity suppliers.

These commitments, obligations and other arrangements will become due in 2025 and beyond. These various purchase commitments and long-term obligations will have an effect on ArcelorMittal's future liquidity and capital resources. For further details on commitments and obligations, please refer to note 9.4 to the consolidated financial statements. ArcelorMittal also has various environmental commitments and asset retirement obligations as of December 31, 2024. For further details on environmental commitments and asset retirement obligations, please refer to note 9.1 to the consolidated financial statements.

The Company expects to service its cash requirements in the near and medium-term with net cash provided by operating activities. In the future, the Company may enter into additional financing facilities if required.

Sources and uses of cash

Years ended December 31, 2024, 2023 and 2022 The following table presents a summary of cash flow of ArcelorMittal:

Summary of cash flow		For the year ended December 31,
(in \$ millions)	2024	2023	2022
Net cash provided by operating activities	4,852	7,645	10,203
Net cash used in investing activities	(4,987)	(5,848)	(4,483)

Net cash provided by operating activities

For the year ended December 31, 2024, net cash provided by operating activities decreased to \$4.9 billion as compared with \$7.6 billion for the year ended December 31, 2023. Net cash provided by operating activities included a marginal operating working capital release of \$0.1 billion (as compared to an operating working capital release of \$1.6 billion in 2023), including a \$0.2 billion and \$0.1 billion inflow from inventories and trade accounts payable, respectively, partially offset by a \$0.2 billion outflow for trade accounts receivable. Activity levels were higher in the fourth quarter of 2024 as compared to the fourth quarter of 2023 with higher inventory and sales volumes, which was offset by lower inventory costs and selling prices.

For the year ended December 31, 2023, net cash provided by operating activities decreased to \$7.6 billion as compared with \$10.2 billion for the year ended December 31, 2022. Net cash provided by operating activities included an operating working capital release of \$1.6 billion as compared to an operating working capital investment of \$1.3 billion in 2022, including an inflow from inventories and trade accounts receivable of \$1.6 billion and \$0.3 billion, respectively, partially offset by an outflow for trade accounts payable of \$0.3 billion. The operating working capital release was driven primarily by lower accounts receivable (due to lower prices and lower volumes, including the impact of normal seasonality at year end), and lower inventories (primarily due to reduced inventory volumes) in the fourth quarter of 2023.

For the year ended December 31, 2022, net cash provided by operating activities increased to \$10.2 billion as compared with \$9.9 billion for the year ended December 31, 2021.

Disclosures about market risk

ArcelorMittal is exposed to a number of different market risks arising from its normal business activities. Market risk is the possibility that changes in raw materials prices, foreign currency exchange rates, interest rates, base metal prices (zinc, nickel, aluminum and tin) and energy prices (oil, natural gas and power) will adversely affect the value of ArcelorMittal's financial assets, liabilities or expected future cash flows.

The fair value information presented below is based on the information available to management as of the date of the consolidated statements of financial position. Although ArcelorMittal is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of this annual report since that date, and therefore, the current estimates of fair value may differ significantly from the amounts presented. The estimated fair values of certain financial instruments have been determined using available market information or other valuation methodologies that require considerable judgment in interpreting market data and developing estimates.

See note 6 to ArcelorMittal's consolidated financial statements for quantitative information about risks relating to financial instruments, including financial instruments entered into pursuant to the Company's risk management policies.

Risk management

ArcelorMittal has implemented strict policies and procedures to manage and monitor financial market risks. Organizationally, supervisory functions are separated from operational functions, with proper segregation of duties. Financial market activities are overseen by the CEO and CFO, the Corporate Finance and Tax Committee and the Executive Office.

All financial market risks are managed in accordance with the Treasury and Financial Risk Management Policy. These risks are managed centrally through Group Treasury by a group specializing in foreign exchange, interest rate, commodity, internal and external funding and cash and liquidity management.

All financial market hedges are governed by ArcelorMittal's Treasury and Financial Risk Management Policy, which includes a delegated authority and approval framework, sets the boundaries for all hedge activities and dictates the required approvals for all Treasury activities. Hedging activity and limits are monitored on an ongoing basis. ArcelorMittal enters into transactions with numerous counterparties, mainly banks and financial institutions, as well as brokers, major energy producers and consumers.

As part of its financial risk management activities, ArcelorMittal uses derivative instruments to manage its exposure to changes in interest rates, foreign exchange rates and

commodities prices. These instruments are principally interest rate, currency and commodity swaps, spots and forwards. ArcelorMittal may also use futures and options contracts.

Counterparty risk

ArcelorMittal has established detailed counterparty limits to mitigate the risk of default by its counterparties. The limits restrict the exposure ArcelorMittal may have to any single counterparty. Counterparty limits are calculated taking into account a range of factors that govern the approval of all counterparties. The factors include an assessment of the counterparty's financial soundness and its ratings by the major rating agencies, which must be of a high quality. Counterparty limits are monitored on a periodic basis.

All counterparties and their respective limits require the prior approval of the Corporate Finance and Tax Committee. Standard agreements, such as those published by the International Swaps and Derivatives Association, Inc. (ISDA) are negotiated with all ArcelorMittal trading counterparties.

Currency exposure

ArcelorMittal seeks to manage each of its entities' exposure to its operating currency. For currency exposure generated by activities, the conversion and hedging of revenues and costs in foreign currencies is typically performed using currency transactions on the spot market and forward market. For some of its business segments, ArcelorMittal hedges future cash flows.

Because a substantial portion of ArcelorMittal's assets, liabilities, sales and earnings are denominated in currencies other than the U.S. dollar (its reporting currency), ArcelorMittal has exposure to fluctuations in the values of these currencies relative to the U.S. dollar. These currency fluctuations, especially the fluctuation of the value of the U.S. dollar relative to the euro, the Canadian dollar, Brazilian real, South African rand, Argentine peso, Indian rupee, Polish zloty and Ukrainian hryvnia, as well as fluctuations in the currencies of the other countries in which ArcelorMittal has significant operations and/ or sales, could have a material impact on its results of operations.

ArcelorMittal faces transaction risk, where its businesses generate sales in one currency but incur costs relating to that revenue in a different currency. For example, ArcelorMittal's subsidiaries may purchase raw materials, including iron ore and coking coal, in U.S. dollar, but may sell finished steel products in other currencies. Consequently, an appreciation of the U.S. dollar will increase the cost of raw materials, thereby negatively impacting the Company's operating margins, unless the Company is able to pass along the higher cost in the form of higher selling prices.

ArcelorMittal faces foreign currency translation risk, which arises when ArcelorMittal translates the financial statements of its subsidiaries, denominated in currencies other than the U.S.

dollar for inclusion in ArcelorMittal's consolidated financial statements.

The tables below illustrate the impact of a 10% increase or decrease between the relevant foreign currencies and the U.S. dollar as of December 31, 2024 and December 31, 2023. A positive sign means an increase in the net debt.

Derivative instruments

ArcelorMittal uses derivative instruments to manage its exposure to movements in interest rates, foreign exchange rates and commodity prices. Changes in the fair value of derivative instruments are recognized in the consolidated statements of operations or in equity according to nature and effectiveness of the hedge.

Derivatives used are non-exchange-traded derivatives such as over-the-counter swaps, options and forward contracts.

For the Company's tabular presentation of information related to its market risk sensitive instruments, please see note 6 to the consolidated financial statements.

Interest rate sensitivity

Cash balances, which are primarily composed of euros and U.S. dollar, are managed according to the short-term (up to one year) guidelines established by senior management on the basis of a daily interest rate benchmark, primarily through short-term currency swaps, without modifying the currency exposure.

Interest rate risk on debt

ArcelorMittal's policy consists of incurring debt at fixed and floating interest rates, primarily in U.S. dollar and euros according to general corporate needs. Interest rate and currency swaps are utilized to manage the currency and/or interest rate exposure of the debt.

For the Company's tabular presentation of the fair values of its short and long term debt, please see note 6 to the consolidated financial statements.

Commodity price risk

ArcelorMittal utilizes a number of exchange-traded commodities in the steel-making process. In certain instances, ArcelorMittal is the leading consumer worldwide of certain commodities. In some businesses and in certain situations, ArcelorMittal is able to pass this exposure on to its customers. The residual exposures are managed as appropriate.

Financial instruments related to commodities (base metals, energy, freight and emission rights) are utilized to manage ArcelorMittal's exposure to price fluctuations.

Hedges in the form of swaps and options are utilized to manage the exposure to commodity price fluctuations.

In case of natural gas, ArcelorMittal has a portfolio of steelmaking assets with approximately 75% of steel being produced through the BF-BOF route which means resulting by-product gases are recycled and utilized as a substitute for natural gas covering a large part of the Company's needs. Overall, the Company has a policy of hedging a portion of its natural gas requirements with other strategic long term hedges in place.

With respect to emission rights, in 2024, the Company has fulfilled its shortfall requirements through the utilization of some of its hedges and through some spot purchases by strategically buying certificates in a planned manner.

For the Company's tabular presentation of information related to its market risk sensitive instruments, please see note 6 to the consolidated financial statements.

In respect of non-exchange traded commodities, ArcelorMittal is exposed to volatility in the prices of raw materials such as iron ore (which is generally correlated with steel prices with a time lag) and coking coal. This exposure is almost entirely managed through long-term contracts, however some hedging of iron ore exposures is made through derivative contracts. For a more detailed discussion of ArcelorMittal's iron ore and

coking coal purchases, see "Operating and financial review — Key factors affecting results of operations—Raw materials".

Outlook

The Company expects higher apparent demand in 2025 as compared to 2024. Outside China, ASC is expected to grow by 2.5% to 3.5% in 2025 as compared to 2024, which is expected to support steel shipment growth in 2025.

ArcelorMittal expects the following demand dynamics by key region in 2025:

• In the U.S., ASC for flat products is expected to grow within the range of 1.0% to 3.0%;
• In Europe, ASC for flat products is expected to grow within a range of 0% to 2.0%;
• In Brazil, the Company expects ASC to be stable in 2025 following strong growth in 2024 by 8.0%;
• In India, the Company expects ASC growth within the range of 6.0% to 7.0%;
• In China, ASC is expected to remain stable.

While near term demand is expected to remain subdued, given the low inventory environment, especially in Europe, the Company is optimistic that restocking activity will supplement real demand improvement in time.

Capital expenditure is expected to remain within the range of \$4.5 billion to \$5.0 billion (of which \$1.4 billion to \$1.5 billion is related to strategic growth capital expenditure and \$0.3 billion to \$0.4 billion on projects related to decarbonization).

Cash flows from operating activities in 2025 is expected to be supported by working capital optimization. The completion of the Company's strategic growth projects is expected to support structurally higher operating income in the coming periods.

All information that is not historical in nature and disclosed under "Operating and financial review", and in particular in this Outlook section, is deemed to be a forward-looking statement. A detailed discussion of principal risks and uncertainties which may cause actual results and events to differ materially from such forward-looking statements is included in the section "Risk factors".

Annual statement from the Chairwoman of ARCG Committee

Dear Shareholders,

In my capacity as Appointments, Remuneration & Corporate Governance Committee ("ARCG") chair I would like to provide you with a summary of the Committee's major focus and an overview of the main actions taken in 2024 and to be taken in 2025.

Safety

Safety continues to be a priority for all levels of the Company. This includes the ARCG Committee working closely with the Sustainability Committee.

The safety audit was completed this year against the backdrop of a necessity to strengthen Group safety performance. We were satisfied with the rigor and extensive analysis that dss+ performed during the nine-month audit of the Group and the Board had a number of meetings to discuss safety and the audit throughout the year. The audit included 155 site audits (including joint ventures) on the three main occupational risks; process safety management audits on the 14 highest risk assets; and a thorough examination of health and safety management practices across the Group. Overall, dss+ confirmed that ArcelorMittal has the right policies and standards but the biggest challenge is to make sure that implementation is uniform across the Group. The ARCG Committee reviewed, strengthened and approved appropriate targets for long and short-term incentives related to health & safety performance improvements and this was an important focus area in 2024.

The Company has committed to implementing the recommendations provided by dss+. Business specific plans have already been developed with clear actions for implementation. The health and safety assurance model has also been strengthened to provide a more comprehensive oversight and the third line will report now directly to the Board.

To support these actions, the ARCG Committee also had requested benchmarking of ArcelorMittal health & safety related incentives with other steel and mining companies. The analysis shows the Company is well aligned with industry best practice.

Business and results

Market conditions were particularly challenging in 2024, with unsustainably low steel prices in the Company's core markets, and aggressive exports from China.

Despite these challenges, ArcelorMittal delivered a resilient financial performance in 2024, which reflects the structural business improvements and the benefits of regional/product diversification. The Company has grown the business, rewarded shareholders all whilst maintaining a strong balance sheet.

ArcelorMittal remains committed to its long-term strategy and has continued to invest in growth and sustainability initiatives. Several recently completed projects such as the Vega CMC in Brazil and a 975MW renewables project in India are performing well. This first completed renewables project started supplying power to AMNS India in September 2024. The Vega CMC project is also fully up and running and produced its first Magnelis® coil.

People strategy, remuneration, nomination, and governance

In April 2024, Mrs. Patricia Barbizet was appointed as chairwoman of the Audit & Risk Committee.

The ARCG Committee members engaged with shareholders in the context of proposals to the Annual General Meeting in May 2024 and specific governance and remuneration related questions of concern to shareholders. Feedback was constructive.

During January 2025, the Lead Independent Director and ARCG Chair conducted the Annual Self-Assessment of the Board of Directors relating to 2024, which has shown that the Company continues to place a ubiquitous focus on the Health and Safety improvement (including fatality reduction), decarbonization and other ESG measures, but also on deployment of capital in the long term and for the interests of investors. The analysis reveals a well-functioning board with strong fundamentals in governance, communication, and strategic oversight, while highlighting specific areas for future focus.

The Committee reviewed the long-term incentive plans for Executive Officers and the ArcelorMittal equity plan for 2025.

During the second half of 2024, the Committee conducted the review of the succession plan for the Company's Executive Office and Executive Vice Presidents. The Committee also worked on the search for a non-executive Director. This process is ongoing.

The ARCG Committee also reviewed and supported the outcome of the Company's Speak Up+ survey-related improvement initiatives, targets and performance.

Climate and Sustainability

ArcelorMittal's existing capabilities in low-carbon metallics and EAF steelmaking puts it in a strategically advantaged position to provide access to low-carbon intensity steel products to customers. ArcelorMittal's XCarb® low-carbon emissions steel, which has a carbon footprint of as low as 300kg per tonne of steel produced, has seen sales grow to approximately 0.4 million tonnes in 2024.

Energy infrastructure, policy and the market environment in Europe have not moved in a favorable direction for decarbonization. Before taking final investment decisions on the Company's decarbonization projects, ArcelorMittal need to have greater clarity on the policy to ensure higher cost steelmaking can be competitive in Europe without a global carbon price.

However, the Company continues to move forward with decarbonization projects which are economic. In 2024, ArcelorMittal started the construction of a 1.1 million-tonne EAF in Gijόn, Spain and is progressing on the EAF expansion at Sestao, Spain to 1.6 million tonnes. Outside of Europe, in the United States, AM/NS Calvert is commissioning a new 1.5 million tonne per annum EAF enhancing its ability to meet automotive demand.

At the same time, the Company continues to secure the resources for decarbonization. In 2024, the Company increased its renewable energy portfolio to 2.1 GW with 975MW commissioned in India and equity investments in Brazil and Argentina.

Going forward

Safety remains the number one focus for 2025, and ArcelorMittal will be monitoring alongside shareholders the progress in implementing the recommendations of the safety audit.

There are certainly several challenges to navigate, but the longterm outlook for steel is positive. ArcelorMittal aims to leverage its geographic presence and strong R&D capabilities to meet stakeholder needs and produce smarter steels – for people and planet.

We are committed to delivering sustainable value to shareholders and thank you for your investment and trust in ArcelorMittal.

Yours Sincerely,

Karyn Ovelmen

Remuneration

Remuneration strategy

The ARCG Committee assists the Board of Directors to maintain a formal and transparent procedure for setting policy on senior management's remuneration and to determine an appropriate remuneration package for senior management. The ARCG Committee should ensure that remuneration arrangements support the strategic aims of the business and enable the recruitment, motivation and retention of senior executives while complying with applicable rules and regulations.

Board oversight

To this end, the Board of Directors has established the ARCG Committee to assist it in making decisions affecting employee remuneration. All members of the ARCG Committee are required to be independent under the Company's corporate governance guidelines, the New York Stock Exchange ("NYSE") standards and the 10 Principles of Corporate Governance of the Luxembourg Stock Exchange.

The members are appointed by the Board of Directors each year after the annual general meeting of shareholders. The members have relevant expertise or experience relating to the purposes of the ARCG Committee. The ARCG Committee makes decisions by a simple majority with no member having a casting vote and is chaired by Ms. Karyn Ovelmen, Lead Independent Director.

Appointments, remuneration and corporate governance committee

One of the tasks of the ARCG Committee is to assist the Board of Directors by providing recommendations specifically related to remuneration and compensation. This includes:

• reviewing and approving corporate and personal goals and objectives relevant to the compensation of the members of the Executive Office, Executive Officers and senior management as deemed appropriate by the committee, and evaluating their performance in light of these goals and objectives.
• making recommendations to the Board of Directors regarding trends in Board remuneration and incentive compensation plans.
• Recommending the Company's framework of remuneration for the members of the Executive Office, Executive Officers and other senior executives as determined by the committee. In making these recommendations, the committee may consider factors that it deems necessary, including a member's total cost of employment (factoring in equity/long term incentives, any perquisites and benefits in kind and pension contributions).
• Approving a report on executive remuneration to be included in the company's annual report.
• Reviewing the analysis of proxy advisory firms in the context of corporate governance compensation.

Individual remuneration is discussed by the ARCG Committee without the person concerned being present. The ARCG Committee Chair presents her decisions and findings to the Board of Directors after each ARCG Committee meeting.

See also "Corporate governance—Board of Directors committees"' for further details and additional responsibilities of the ARCG Committee.

Remuneration policy

The ARCG Committee has set policies applied to senior management on base salary, short-term incentives and longterm incentives. According to the Shareholders Right Directive II, which was transposed into Luxembourg law in August 1, 2019, the remuneration policies must be approved at the Annual General Meeting of shareholders at least every 4 years and whenever there is a material change. The Company submits the remuneration report for the prior year for shareholder approval at each AGM.

Scope

ArcelorMittal's remuneration philosophy and framework apply to the following groups of senior management:

• the Executive Chairman and the CEO; and
• the CFO and other Executive Officers.

The remuneration philosophy and governing principles also apply, with certain limitations, to a wider group of employees including Executive Vice Presidents, Vice Presidents, General Managers and Managers.

Remuneration philosophy

ArcelorMittal's remuneration philosophy for its senior management is based on the following principles:

• provide total remuneration competitive with executive remuneration levels of peers of similar size, scope and industry:
  • Korn Ferry (KF) and WillisTowersWatson (WTW) provide benchmarking services to ArcelorMittal for all Management Committee members, an average between KF and WTW data is performed;
  • For the Steel division: Large industry industrial segment including metals, chemicals, mining, transport, energy & utilities, upper revenues range;
  • For the Mining division: Large companies with a significant mining divisions or companies similar to ArcelorMittal Mining division;
  • Data are linked to each local market.
• encourage and reward performance that will lead to long-term enhancement of shareholder value; and
• promote internal pay equity by providing base pay and total remuneration levels that reflect the role, job size and responsibility as well as the performance and effectiveness of the individual.

Remuneration framework

The ARCG Committee develops proposals for senior management remuneration annually for the Board of Directors' consideration. Such proposals include the following components:

• fixed annual salary;
• short-term incentives (i.e., performance-based bonus); and
• long-term incentives (i.e., RSUs and/or PSUs).

The Company does not have any deferred compensation plans for senior management, including the Executive Chairman and CEO.

The following table provides an overview of the remuneration policy applied by the ARCG:

Short-term incentives

Targets associated with ArcelorMittal's 2024 Annual Performance Bonus Plan were aligned with the Companies' strategic objectives of improving health and safety performance and overall business performance and competitiveness.

For the Executive Chairman and the CEO, the 2024 annual performance bonus formula is based on the achievement of the following performance targets:

• EBITDA targets at Group level: 40% (acts as circuit breaker for financial measures EBITDA and FCF);
• FCF targets at Group level: 25%;
• Gap to competition targets at Group level: 20%; and
• Health and safety performance targets at Group level: 15%. In order to help focus attention, energy and resources on detecting and eliminating the causes of serious injury or fatality precursors, the Company has moved to a target of potential severe injury or fatality. To emphasize this priority, the fatality frequency rate acts as a circuit breaker for the Health & Safety component. The circuit breaker is set at a fatality frequency rate of nil.

For the Executive Chairman and CEO, 100% achievement of the agreed performance targets results in an annual performance bonus which equals 120% of base salary.

For the CFO and other Executive Officers, the 2024 annual performance bonus formula was tailored for their respective positions and is generally based on the following performance targets:

• EBITDA targets at Group, segment or Business unit level (acts as circuit breaker for financial measures EBITDA and FCF);
• FCF targets at Group, segment or Business unit level;
• Gap to competition targets at Group level, segment or Business unit level;
• Health and safety performance targets at Group, Segment or Business unit level (fatalities act as circuit breaker for this component).The circuit breaker is set at a facility frequency rate of 0.012 for 2024, 0.006 for 2025 and nil for 2026.

For the CFO and other Executive Officers, 100% achievement of the agreed performance targets results in an annual performance bonus which equals 80% of base salary in general (depends on the region).

For the calculation of the annual performance bonus, the achievement level of every performance target is calculated separately, and these are added up.

Individual performance and assessment ratings define the individual annual performance bonus multiplier that will be applied to the annual performance bonus calculated based on actual performance against the performance measures. Those individuals who consistently perform at expected levels will have an individual multiplier of 1. For outstanding performers, an individual multiplier of up to 1.5 may cause the annual performance bonus pay-out to be higher than 200% of the target annual performance bonus, up to 360% of the target annual performance bonus being the absolute maximum for the Executive Chairman and the CEO. Similarly, a reduction factor will be applied for those at the lower end.

In exceptional circumstances, the ARCG Committee can exercise discretion in the final determination of the annual performance bonus.

The achievement level of performance for the annual performance bonus for the Executive Chairman, the CEO, the CFO and the other Executive Officers is summarized as follows:

Functional level	Target achievement threshold @ 80%	Target achievement @ 100%	Target achievement @ 120%	Target achievement ≥ ceiling @ 140%
Executive Chairman and CEO	60% of base pay	120% of base pay	180% of base pay	240% of base pay
CFO and Executive Officers	40% of base pay	80% of base pay	120% of base pay	160% of base pay

ArcelorMittal Equity Incentive Plan

ArcelorMittal operates a long-term incentive plan ("the ArcelorMittal Equity Incentive Plan") to incentivize shareholder wealth creation in excess of performance of a peer group and incentivize executives to achieve strategy. The ArcelorMittal Equity Incentive Plan is intended to align the interests of the Company's shareholders and eligible employees by allowing them to participate in the success of the Company. The ArcelorMittal Equity Incentive Plan provides for the grant of RSUs and PSUs to eligible employees of the Company (including the Executive Officers) and is designed to incentivize employees, improve the Company's long-term performance and retain key employees.

The maximum number of PSUs and RSUs available for grant during any given year is subject to the prior approval of the Company's shareholders at the annual general meeting. The 2020, 2021, 2022, 2023 and 2024 Caps for the number of PSUs/RSUs that may be allocated to the Executive Office and other retention and performance based grants below the Executive Office level, were approved at the annual general meetings on June 8, 2021, May 4, 2022 ,on May 2, 2023 and on April 30, 2024, respectively, at a maximum of 3,500,000 shares, 3,500,000 shares, 3,500,000 shares and 5,500,000 shares, respectively.

RSUs granted under the ArcelorMittal Equity Incentive Plan are designed to provide a retention incentive to beneficiaries. RSUs are subject to "cliff vesting" after 3 years with 100% of the grant vesting on the third anniversary of the grant contingent upon the continued active employment of the beneficiary within the Company.

Awards in connection with PSUs are subject to the fulfillment of performance criteria such as ROCE, TSR, EPS and gap to competition (until 2022). Since 2021, the performance criteria for the PSUs for the Executive Office and Executive Officers include an ESG criteria comprised of a health & safety, a climate action and a diversity & inclusion ("D&I") target. For health & safety, the target is to halve the fatality frequency rate versus a defined baseline (the baseline is the adjusted average frequency rate over 5 years before the grant). For D&I, the target up to this point has been to reduce the gap between the Company's 2030 target of having 25% women in management and 2020 baseline. Good progress has been made in strengthening the number of women in leadership, and given the critical importance of rapidly improving safety results across the Company, ArcelorMittal will give consideration to increasing the safety component. For climate, the CO2 emission target has been set to be reached by the end of the vesting period.

Other benefits

In addition to the remuneration described above, other benefits may be provided to senior management and, in certain cases, other employees. These other benefits can include insurance, housing (in cases of international transfers), car allowances and tax assistance.

SOX 304 and clawback policy

Under Section 304 of the Sarbanes-Oxley Act, the SEC may seek to recover remuneration from the CEO and CFO of the Company in the event that it is required to restate accounting information due to any material misstatement thereof or as a result of misconduct in respect of a financial reporting requirement under the U.S. securities laws (the "SOX Clawback").

Under the SOX Clawback, the CEO and the CFO may have to reimburse ArcelorMittal for any short-term incentive or other incentive-based or equity-based remuneration received during the 12-month period following the first public issuance or filing with the SEC (whichever occurs first) of the relevant filing, and any profits realized from the sale of ArcelorMittal securities during that 12-month period.

In October 2022, the SEC adopted final rules implementing the Dodd-Frank requirement for issuers to recover incentive-based compensation erroneously paid to current and former executive officers due to an accounting restatement. These clawback rules required listing exchanges, such as the NYSE, to adopt clawback standards as from the fourth quarter of 2023, with

issuers required to implement and disclose "no fault" clawback policies that meet strict recovery standards for restatements, within 60 days thereafter.

The Board of Directors, through its ARCG Committee, adopted its own clawback policy in 2012, which was updated in 2023 (the "Clawback Policy"), to reflect the Company's structural changes and comply with the new rules.

The Clawback Policy applies to all Executive Officers and covers cash short-term incentives and any other incentivebased or equity-based remuneration, as well as profits from the sale of the Company's securities ("Covered Compensation") received during the three completed fiscal years of the Company immediately preceding a the Restatement Date (as defined in the policy) and any transition period (that results from a change in the Company's fiscal year) of less than nine months within or immediately following those three completed fiscal years. Compensation is deemed to be received in the Company's fiscal period during which the Financial Reporting Measure specified in the Incentive-based Compensation award is attained (capitalized terms as defined in the policy).

Under the Clawback Policy, ArcelorMittal will recover reasonably promptly erroneously paid Covered Compensation in the event it is required to prepare an accounting restatement due to the material noncompliance of ArcelorMittal with any financial reporting requirement under the U.S. securities laws, including any required accounting restatement to correct an error in a previously issued financial statement that is material to the previously issued financial statement, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

Employees

As of December 31, 2024, ArcelorMittal employed approximately 125,416 full time equivalents ("FTE") employees directly, as well as a large number of contractors. The Company recruits, hires, promotes and retains employees based on merit and demonstrated skills.

The table below sets forth the number of FTE employees respectively by segment as of the end of each of the past three years.

The people strategy

To meet the evolving needs of its people and address the challenges of a shifting skills economy, technological advancements, and generational transitions, ArcelorMittal remains committed to delivering its people strategy, launched in 2022. The strategy is built around ArcelorMittal's fundamental purpose to create smarter steels for people and the planet. This strategy seeks to boost talent and continuously foster a safety-first, people-driven culture that ensures sustainable performance and enables the Company to deliver on its purpose.

Employee development

Attracting, developing and retaining the right people continues to be a strategic priority for ArcelorMittal in sustaining a highperforming organization.

With strong competition for the best talent, ArcelorMittal is committed to ensuring the Company is an aspirational workplace—one where employees feel safe, respected and valued. This also means building a culture that constantly keeps employees engaged, motivated, and eager to learn and excel.

Employee development, which includes succession planning and the development of early career talents plays a crucial role in building a high-performing organization. The Company strives to provide employees a clear career pathway, supported by continuous training and ongoing initiatives to develop both technical and behavioral skills. A dedicated process helps identify high potential employees ("HiPos") and manage the succession of key roles.

In 2024, the Company intensified its efforts to develop employees' skills and accelerate the readiness of its HiPos to take on increased responsibilities. A strong focus was placed

on having the right people in the right roles at the right time, strengthening key succession plans, and preparing future leaders. Efforts also included anticipating and filling vacancies; building a robust and qualified leadership pipeline; encouraging individual and sustained performance; and fostering talent retention through recognition, empowerment, and meaningful work.

To further support career growth, ArcelorMittal enhanced its communications initiatives to increase the visibility of global career opportunities, ensuring employees are aware of potential paths for advancement within the organization.

The Company also took steps to enhance the quality of its succession planning, ensuring stronger alignment between potential successors and their career aspirations.

In 2024, the Company experienced a significant increase in virtual learning engagement at ArcelorMittal University ("AMU"), further expanding its global community. Employees across the Group invested an average of 5.1 hours each to online learning with more than 149,000 active learners (a 48% increase year-on-year) logging over 760,000 hours (a 27% increase year-on-year).

The Company continued offering world-class leadership programs through AMU. Delivered in a blended format combining face-to-face (where possible) with digital sessions —these programs support the development of talent and future leaders. In 2024, 16 leadership programs were launched engaging 462 employees.

A new development program called 'Thrive' was introduced in North America, Brazil, and Europe to help employees accelerate their career growth. The program matches individuals with suitable roles and career opportunities based on their preferences, skills and qualifications.

ArcelorMittal's Group Mentoring Program also remained a vital resource, offering employees an opportunity to engage in a structured mentoring relationship with an experienced leader. In 2024, more than 1,900 mentorship hours were invested as part of the program with 426 active mentor-mentee pairs as of December 31, 2024.

In addition, the Company continued refining its employee systems landscape, improving processes in recruitment, performance, career development, learning, and compensation. These enhancements provide a stronger infrastructure for analyzing data and identifying areas for continuous improvement, reinforcing ArcelorMittal's commitment to employee growth and engagement.

Speak Up +, the global employee survey

For the past few years, ArcelorMittal's Speak Up + survey has been the Group's flagship employee engagement tool. It gathers insights from professionals and leadership on their experience working at ArcelorMittal, what the Company does well and areas for improvement.

In 2024, ArcelorMittal continued to listen to employees' voices through these surveys, which serve as the ongoing vehicle to help the Company's leaders stay attuned to the organization in a rapidly changing environment. The goal is to track engagement levels across the Group, understand employees' aspirations, and empower leaders to address potential issues proactively.

The survey is conducted twice a year. The outcomes from each Speak Up + survey are compared to internal benchmarks over time and external industry peers. This enables leaders to identify strengths, detect risks—such as attrition— and take actions to enhance employee engagement.

Based on survey outcomes, concrete actions are continuously developed and implemented to address employee concerns and drive engagement.

Equal opportunity and non-discrimination

ArcelorMittal values bringing together fresh perspectives and experiences to the business as part of its ambition to be an employer of choice. The Company is present in over 60 countries and aims to have employees which represent all differences. In 2022, the Company defined a clear roadmap to ensure equal opportunity and nondiscrimination. Subsequently, a strategic framework was launched in 2024, which includes best practices as a reference guide for all segments and plants to achieve equality for all employees.

The Company continuously reviews and benchmarks its policies and HR practices to build an inclusive and merit based culture that empowers all talents. This is designed to ensure that all qualified candidates have equal opportunities ultimately based on individual merit.

In 2024, women held 19% of management positions across the Group based on merit, compared to 17.3% in 2023.

As of December 31, 2024, women held four of the nine positions on the Board of Directors.

Collective Labor Agreements ("CLAs")

In multiple regions globally, ArcelorMittal employees are represented by trade unions and the Company actively engages in collective bargaining agreements with employee organizations at specific locations. The description below provides an overview of the current status of specific agreement and relationships.

The Company is committed to open, respectful and transparent social dialogue at all of its operations, to maintain strong employee relations, and to provide a safe, healthy and quality working lives for all its workers.

In the current inflationary environment, the Company understands that salary increases for workers is a question of high sensitivity. ArcelorMittal is respecting its commitment to

social dialogue and all entities have regular discussions and negotiations on salary policy with their respective unions.

The Joint Global Health and Safety Agreement between the Company and IndustriALL global trade union, signed in 2008, remained in effect in 2024. This agreement recognizes the vital role played by trade unions in improving health and safety. It sets out minimum standards for every site where the Company operates with the objective of achieving world-class performance. As a result of this agreement, the Joint Global H&S Committee, composed of 16 representatives in 2024 (12 in 2023) of management and the unions was created to identify areas for improvement and harmonize safety performance across the Group. The Joint Global H&S Committee only deals with issues related to H&S and does not act as a negotiation committee on behalf of unions or management. One of its primary priorities is centered around overseeing deployment and monitoring the compliance of local joint H&S panels. This involves developing guidelines to progress and training programs, conducting site visits to assess implementation and offering suggestions for improvement. Additionally, the Joint Global H&S Committee provides recommendations on transversal and global topics to enhance overall safety measures.

In 2024, one physical meeting was organized at the Group level to discuss transversal specific topics with regard to H&S. One of the main topics of this meeting was the collective review and the update of the committee charter. In addition, other safety training and coaching programs, such as "Take Care" Trainings as well as a dss+ lead "Area of Transformation" program continued to be rolled out in 2024 in order to support the "Journey to Zero" program aimed at reducing the amount of injuries and fatalities in the Company to zero. See "Business overview—Sustainable development— Health and Safety".

In 2024, several entities and countries engaged in entering or renewal of CLAs.

In North America, employees at various sites continue to work under collective agreements that remain valid. In May 2024, the Company's steel plant in Lazaro Cardenas, Mexico and mine located in Tenecia La Mira in the Mexican state of Michoacán was impacted by an illegal blockade by a group of workers due to their dissatisfaction with the distribution of profit sharing by the Company. Ultimately, the Company approved a new settlement with unions with an agreement to end the strike in July 2024.

In South America, inflation trends varied across different countries. Brazil experienced a deceleration in inflation, with collective bargaining agreements generally granting adjustments equivalent to the inflation rate. Argentina has been experiencing a high inflation rate since several years. The situation remained the same in 2024 and the negotiations for salary increase are still in progress.

In Europe, four meetings were conducted in 2024 to inform the European Works Council ("EWC") representatives about the

H&S and business performance and outlook regarding the Company's European operations. Throughout the year, three meetings with the Select Committee were held, alongside a Plenary Assembly in December 2024. Negotiations aiming to revise the EWC agreement are expected to finalize by the end of the first quarter of 2025.

In France, a one-year salary agreement for 2024 was signed in December 2023, covering most legal entities. Negotiations for 2025 were conducted at most of the French sites at the end of 2024 and resulted in the payment of a premium. ArcelorMittal Méditerranée announced in July 2024 that it would continue to operate with only one of the two blast furnaces in the foreseeable future due to weak market conditions. Discussions with employee representatives in order to manage workforce adaptation started in 2024 and are still ongoing. All employees are covered by collective labor agreements.

In Luxembourg, social elections were held on March 12, 2024 which led to the election of new staff representatives and deputies, with a new staff delegation replacing the previous one.

In 2024, Germany continued to experience high energy prices, impacting costs and market conditions negatively, despite low inflation. A one-off payment was made to all employees under previous collective bargaining agreements.

In 2024, at ArcelorMittal Poland, a successful negotiation of the CLA was achieved with trade unions. The management also invited trade union representatives to the Supervisory Board, promoting transparency and inclusive decision-making. About 99% of employees are covered by the CLA, with only top executives excluded.

In Spain, a temporary layoff plan was agreed upon in late 2023 due to market conditions and extended through 2024. A framework agreement for labor relations was signed with most unions in May 2023, and all local CLAs were finalized by mid-2024, covering about 80% of the workforce. Additionally, a layoff plan for employees born in 1962 was agreed in May 2024, to address the labor implications of decarbonization initiatives as per the Memorandum of Understanding between the Spanish government and ArcelorMittal.

In 2024, the situation in Ukraine continued to be difficult in terms of personnel due to the war with Russia. The martial law imposed by the country's government since February 2022, which, among other things, limits the labor rights of employees and trade unions (such as the right to strike; the right to vacation, etc.) remains in force. In 2024, more than 3,000 of AMKR's employees were mobilized and more than 220 died in the war or went missing in action. The facility continued to experience a significant outflow of personnel, mainly men, due to mobilization. As a consequence, it launched recruitment campaigns to attract women and young people. Despite operating at 30-50% of production capacity, AMKR maintained work positions and wages for its 18,000 workers avoiding layoffs.

In South Africa, out of the 5,997 employees at AMSA, 4,182 employees (70% of the workforce) are covered by a CLA/ Bargaining council agreement concluded between management and the recognized trade unions i.e. NUMSA and Solidarity trade unions. The CLA will expire in March 2026. From April 2023 to March 2024, the agreement comprised a range of provisions encompassing a 6.5% remuneration adjustment for all employees within the bargaining unit. It further incorporated an ex-gratia premium, enhancements to the medical aid subsidy and a 6.5% increase in all allowances excluding retention and protected allowances. The company's contribution to medical aid will progressively rise, reaching 70% by 2026 while the employee's contribution will decrease to 30%. In 2024, the company gave a 5% salary increase to permanent bargaining and package category employees.

Throughout 2024, ArcelorMittal Mining maintained a productive engagement with its trade unions and communities where it operates. 76% of the workforce is unionized in ArcelorMittal's operations in Canada and 82% in ArcelorMittal's operations in Liberia.

Corporate governance

This section describes the corporate governance practices of ArcelorMittal for the year ended December 31, 2024.

Board of Directors and senior management

ArcelorMittal is governed by a Board of Directors and managed by the senior management. As described in "Directors and senior management" above, ArcelorMittal's senior management is comprised of the Executive Office comprising the Executive Chairman, Mr. Lakshmi N. Mittal and the CEO, Mr. Aditya Mittal. The Executive Office is supported by a team of nine other Executive Officers, who together encompass the key regions and corporate functions. As of December 31, 2024, the average age and serving period of board members is 61 years and 10 years, respectively. A number of corporate governance provisions in the Articles of Association of ArcelorMittal reflect provisions of the Memorandum of Understanding signed on June 25, 2006 (prior to Mittal Steel Company N.V.'s merger with Arcelor), amended in April 2008 and which mostly expired on August 1, 2009. For more information about the Memorandum of Understanding, see "Additional information—Material contracts—Memorandum of Understanding".

ArcelorMittal fully complies with the 10 Principles of Corporate Governance of the Luxembourg Stock Exchange. This is explained in more detail in "—Other corporate governance practices" below. ArcelorMittal also complies with the New York Stock Exchange Listed Company Manual as applicable to foreign private issuers. There are no significant differences between the corporate governance practices of ArcelorMittal

and those required of a U.S. domestic issuer under the Listed Company Manual of the New York Stock Exchange.

Board of Directors

9 Members

Non-executive and independent directors Non-executive and non-independent directors Executive directors (CEO and Executive Chairman)

Gender representation on board

The Board of Directors is in charge of the overall governance and direction of ArcelorMittal. It is responsible for the performance of all acts of administration necessary or useful

in furtherance of the corporate purpose of ArcelorMittal, except for matters reserved by Luxembourg law or the Articles of Association to the general meeting of shareholders. The Articles of Association provide that the Board of Directors is composed of a minimum of 3 and a maximum of 18 members.

The Articles of Association provide that directors are elected and removed by the general meeting of shareholders by a simple majority of votes cast. Other than as set out in the Company's Articles of Association, no shareholder has any specific right to nominate, elect or remove directors. Directors are elected by the general meeting of shareholders for threeyear terms. In the event that a vacancy arises on the Board of Directors for any reason, the remaining members of the Board of Directors may by a simple majority elect a new director to temporarily fulfill the duties attaching to the vacant post until the next general meeting of the shareholders.

For further information on the composition of the Board of Directors, including the expiration of each Director's term and the period during which each Director has served, see section "—Directors and senior management " above.

Mr. Lakshmi N. Mittal was elected Chairman of the Board of Directors on May 13, 2008. Mr. Lakshmi N. Mittal was also ArcelorMittal's CEO until February 11, 2021. Mr. Lakshmi N. Mittal was re-elected to the Board of Directors for a three-year term at the annual general meeting of shareholders on May 2, 2023.

A director is considered "independent" if:

• (a) he or she is independent within the meaning of the New York Stock Exchange Listed Company Manual, as applicable to foreign private issuers,
• (b) he or she is unaffiliated with any shareholder owning or controlling more than two percent of the total issued share capital of ArcelorMittal, and
• (c) the Board of Directors makes an affirmative determination to this effect.

For these purposes, a person is deemed affiliated to a shareholder if he or she is an executive officer, a director who also is an employee, a general partner, a managing member or a controlling shareholder of such shareholder. The 10 Principles of Governance of the Luxembourg Stock Exchange, which constitute ArcelorMittal's domestic corporate governance code, require ArcelorMittal to define the independence criteria that apply to its directors, which are described in article 8.1 of its Articles of Association.

Specific characteristics of the director role

Required share ownership

Lead Independent Director - minimum of 6,000 ordinary shares Non-executive directors - minimum of 4,000 ordinary shares

Maximum 12 year service (independent directors)

May not serve on the boards of directors of more than four publicly listed companies (nonexecutive directors)

Required to sign the Company's Code of Business Conduct and confirm their adherence annually

The Company's Articles of Association do not require directors to be shareholders of the Company. The Board of Directors nevertheless adopted a share ownership policy on October 30, 2012, that was amended on November 7, 2017, considering that it is in the best interests of all shareholders for all non-executive directors to acquire and hold a minimum number of ArcelorMittal ordinary shares in order to better align their long-term interests with those of ArcelorMittal's shareholders. The Board of Directors believes that this share ownership policy will result in a meaningful holding of ArcelorMittal shares by each non-executive director, while at the same time taking into account the fact that the share ownership requirement should not be excessive in order not to unnecessarily limit the pool of available candidates for appointment to the Board of Directors. Directors must hold their shares directly or indirectly, and as sole or joint beneficiary owner (e.g., with a spouse or minor children), at the latest within three years of his or her election to the Board of Directors. Each director will hold the shares acquired on the basis of this policy for so long as he or she serves on the Board of Directors. Directors purchasing shares in compliance with this policy must comply with the ArcelorMittal Insider Dealing Regulations and, in particular, refrain from trading during any restricted period, including any such period that may apply immediately after the Director's departure from the Board of Directors for any reason.

On October 30, 2012, the Board of Directors also adopted a policy that places limitations on the terms of independent directors as well as the number of directorships that directors may hold in order to align the Company's corporate governance practices with best practices in this area (as highlighted in the table above). Nevertheless, the Board of Directors may, by way of exception to this rule, make an affirmative determination, on a case-by-case basis, that a Director may continue to serve beyond the 12-year rule if the Board of Directors considers it to be in the best interest of the Company based on the contribution of the Director involved taking into consideration the balance between the knowledge, skills, experience of the director and the need for renewal of the Board.

As membership of the Board of Directors represents a significant time commitment, the policy requires both executive and non-executive directors to devote sufficient time to the discharge of their duties as a Director of ArcelorMittal. Directors are therefore required to consult with the Chairman and the Lead Independent Director before accepting any

additional commitment that could conflict with or impact the time they can devote to their role as a Director of ArcelorMittal. A non-executive Director's service on the board of directors of any subsidiary or affiliate of ArcelorMittal or of any non-publicly listed company is not taken into account for purposes of complying with the service limitation.

Although non-executive directors of ArcelorMittal who change their principal occupation or business association are not necessarily required to leave the Board of Directors, the policy requires each non-executive director, in such circumstances, to promptly inform the Board of Directors of the action he or she is contemplating. Should the Board of Directors determine that the contemplated action would generate a conflict of interest, such non-executive director would be asked to tender his or her resignation to the Chairman of the Board of Directors, who would decide to accept the resignation or not.

None of the members of the Board of Directors, including the executive directors, have entered into service contracts with ArcelorMittal or any of its subsidiaries that provide for any form of remuneration or for benefits upon the termination of their term. All non-executive Directors of the Company signed the Company's Appointment Letter, which confirms the conditions of their appointment by the General Meeting of the Shareholders including compliance with certain non-compete provisions, the 10 Principles of Corporate Governance of the Luxembourg Stock Exchange and the Company's Code of Business Conduct.

The remuneration of the members of the Board of Directors is determined on a yearly basis by the annual general meeting of shareholders.

Share transactions by management

In compliance with laws prohibiting insider dealing, the Board of Directors of ArcelorMittal has adopted insider dealing regulations, which apply throughout the ArcelorMittal group. These regulations are designed to ensure that insider information is treated appropriately within the Company and avoid insider dealing and market manipulation. Any breach of the rules set out in this procedure may lead to criminal or civil charges against the individuals involved, as well as disciplinary action by the Company.

Operation

General

The Board of Directors and the Board committees may engage the services of external experts or advisers as well as take all actions necessary or useful to implement the Company's corporate purpose. The Board of Directors (including its three committees) has its own budget, which covers functioning costs such as external consultants, continuing education activities for directors and travel expenses.

Meetings

The Board of Directors meets when convened by the Chairman of the Board or any two members of the Board of Directors. The Board of Directors holds physical meetings at least on a quarterly basis as five regular meetings are scheduled per year. The Board of Directors holds additional meetings if and when circumstances require, in person or by teleconference and can take decisions by written circulation, provided that all members of the Board of Directors agree.

In 2024, the Board of Directors held 7 meetings with 100% of the average attendance rate.

7 meetings (2024)

100% Average attendance rate

In order for a meeting of the Board of Directors to be validly held, a majority of the directors must be present or represented, including at least a majority of the independent directors. In the absence of the Chairman, the Board of Directors will appoint a chairman by majority vote for the meeting in question. The Chairman may decide not to participate in a Board of Directors' meeting, provided he has given a proxy to one of the directors who will be present at the meeting. For any meeting of the Board of Directors, a director may designate another director to represent him or her and vote in his or her name, provided that the director so designated may not represent more than one of his or her colleagues at any time.

Each director has one vote and none of the directors, including the Chairman, has a casting vote. Decisions of the Board of Directors are made by a majority of the directors present and represented at a validly constituted meeting, except for the decisions of the Board of Directors relating to the issue of any financial instruments carrying or potentially carrying a right to equity pursuant to the authorization conferred by article 5.5 of the Articles of Association, which shall be taken by a majority of two-thirds of the directors present or represented at a validly constituted meeting.

Lead Independent Director

Mrs. Karyn Ovelmen was elected by the Board of Directors as ArcelorMittal's Lead Independent Director at the board meeting held on May 2, 2023.

The agenda of each meeting of the Board of Directors is decided jointly by the Chairman of the Board of Directors and the Lead Independent Director.

Separate meetings of independent directors

The independent members of the Board of Directors may schedule meetings outside the presence of non-independent directors. Systematic executive sessions take place at the end of each committee and of each board meeting. Nineteen meetings of the independent directors outside the presence of management were held in 2024.

Annual self-evaluation

The Board of Directors decided in 2008 to start conducting an annual self-evaluation of its functioning in order to identify potential areas for improvement. The first self-evaluation process was carried out in early 2009. The self-evaluation process includes structured interviews between the Lead Independent Director and each director and covers the overall performance of the Board of Directors, its relations with senior management, the performance of individual directors, and the performance of the committees. The process is supported by the Company Secretary under the supervision of the Chairman and the Lead Independent Director. The findings of the self-evaluation process are examined by the ARCG Committee and presented with recommendations from the ARCG Committee to the Board of Directors for adoption and implementation. Suggestions for improvement of the Board of Directors' process based on the prior year's performance and functioning are implemented during the following year.

The 2024 Board of Directors' self-evaluation was completed by the Board on February 5, 2025. The Board of Directors was of the opinion that it and the management had cooperated successfully during 2024. Strong focus has continued to be given on health and safety, on environmental matters, on Board succession planning as well as on the operations in India and Europe. The Board of Directors reviewed the practical implementation of the governance structure and considered it was working well. The Board set new priorities for discussion and review and identified a number of priority topics for 2025.

The Board of Directors believes that its members have the appropriate range of skills, knowledge and experience, as well as the degree of perspectives, experiences and background necessary to enable it to effectively govern the business. The Board of Directors composition is reviewed on a regular basis and additional skills and experience are actively searched for in line with the expected development of ArcelorMittal's business as and when appropriate.

Directors and its committees are therefore required to ensure that the Board has the right balance of skills, experience, independence and knowledge necessary to perform its role in accordance with the highest standards of governance.

Diverse skills, perspectives, knowledge, backgrounds and experience are required in order to effectively govern a global business the size of the Company's operations. The Board of

The Company's directors must demonstrate unquestioned honesty and integrity, preparedness to question, challenge and critique constructively, and a willingness to understand and commit to the highest standards of governance. They must be committed to the collective decision-making process of the Board of Directors and must be able to debate issues openly and constructively, and question or challenge the opinions of others. Directors must also commit themselves to remain actively involved in Board decisions and apply strategic thought to matters at issue. They must be clear communicators and good listeners who actively contribute to the Board in a collegial manner. Each director must also ensure that no decision or action is taken that places his or her interests before the interests of the business. Each director has an obligation to protect and advance the interests of the Company and must refrain from any conduct that would harm it.

In order to govern effectively, non-executive directors must have a clear understanding of the Company's strategy, and a thorough knowledge of the ArcelorMittal group and the industries in which it operates. Non-executive directors must be sufficiently familiar with the Company's core business to effectively contribute to the development of strategy and monitor performance.

With specific regard to the non-executive directors of the Company, the composition of the group of non-executive directors should be such that the combination of experience, knowledge and independence of its members allows the Board to fulfill its obligations towards the Company and other stakeholders in the best possible manner.

The ARCG Committee ensures that the Board of Directors is comprised of high-caliber individuals whose background, skills, experience and personal characteristics enhance the overall profile of the Board and meets its needs by nominating high quality candidates for election to the Board by the general meeting of shareholders.

Board profile

The key skills and experience of the directors, and the extent to which they are represented on the Board of Directors and its committees, are set out below. In summary, the nonexecutive directors contribute:

Renewal

The Board of Directors plans for its own succession, with the assistance of the ARCG Committee. In doing this, the Board of Directors:

• considers the skills, backgrounds, knowledge, and experience necessary to allow it to meet the corporate purpose;
• assesses the skills, backgrounds, knowledge and experiences currently represented;
• identifies any inadequate representation of those attributes and agrees the process necessary to ensure a candidate is selected who brings them to the Board of Directors; and
• reviews how Board performance might be enhanced, both at an individual director level and for the Board as a whole.

The Board believes that orderly succession and renewal is achieved through careful planning and by continuously reviewing the composition of the Board.

When considering new appointments to the Board, the ARCG Committee oversees the preparation of a position specification that is provided to an independent recruitment firm retained to conduct a global search, taking into account, among other factors, geographic location, nationality and gender. In addition to the specific skills, knowledge and experience required of the candidate, the specification contains the criteria set out in the ArcelorMittal Board profile.

Director induction, training and development The Board considers that the development of the directors' knowledge of the Company, the steel-making and mining industries, and the markets in which the Company operates is an ongoing process. To further bolster the skills and knowledge of directors, the Company set up a continuous development program in 2009.

Upon his or her election, each new non-executive director undertakes an induction program specifically tailored to his or her needs and includes ArcelorMittal's long-term vision centered on the concept of "Safe Sustainable Steel".

The Board's development activities include the provision of regular updates to directors on each of the Company's products and markets. Non-executive directors may also participate in training programs designed to maximize the effectiveness of the directors throughout their tenure and link in with their individual performance evaluations. The training and development program may cover not only matters of a business nature, but also matters falling into the environmental, social and governance area.

Structured opportunities are provided to build knowledge through initiatives such as visits to plants and mine sites and business briefings provided at Board meetings. Non-executive directors also build their Company and industry knowledge through the involvement of the Executive Office and other senior employees in Board meetings. Business briefings, site visits and development sessions underpin and support the Board's work in monitoring and overseeing progress towards the corporate purpose of creating long-term shareholder value through the development of the ArcelorMittal business in steel and mining. The Company therefore continuously builds directors' knowledge to ensure that the Board remains up-todate with developments within the Company's segments, as well as developments in the markets in which the Company operates.

During the year, non-executive directors participated in the following activities:

• comprehensive business briefings intended to provide the directors with a deeper understanding of the Company's activities, environment, key issues and strategy of the Company's segments. These briefings are provided to the Board of Directors by senior executives, including Executive Office members. The briefings provided during the course of 2024 covered many areas. In particular, a strong emphasis has been given to health and safety processes, fatality prevention, environment and climate change. Specific major acquisitions were reviewed. In addition, cyber security, risk management, corporate responsibility, carbon reduction strategy in steelmaking, capital allocation process and strategy were covered. Business briefings took place at Board and committee meetings;
• briefing meetings with the Company executives in charge of specific business segments or markets;
• site visits of directors to plants and R&D centers; and
• development sessions on specific topics of relevance, such as health and safety, commodity markets, HR, investor relations, accounting, the world

economy, changes in corporate governance standards, directors' duties and shareholder feedback.

The ARCG Committee oversees director training and development. This approach allows induction and learning opportunities to be tailored to the directors' committee memberships, as well as the Board of Directors' specific areas of focus. In addition, this approach ensures a coordinated process in relation to succession planning, Board renewal, training, development and committee composition, all of which are relevant to the ARCG Committee's role in securing the supply of talent to the Board.

Board of Directors committees

The Board of Directors has three committees:

• the Audit & Risk Committee,
• the ARCG Committee, and
• the Sustainability Committee.

Audit & Risk Committee

In 2024, 6 meetings of the Audit & Risk Committee were held with an attendance rate of 100%.

The primary function of the Audit & Risk Committee is to assist the Board in fulfilling its oversight responsibilities by reviewing:

• the integrity of the financial reports and other financial information provided by the Company to any governmental body or the public;

The Audit & Risk Committee must be composed solely of independent members of the Board of Directors. The members are appointed by the Board of Directors each year after the annual general meeting of shareholders. The Audit & Risk Committee is comprised of four members, all of whom must be independent under the Company's corporate governance guidelines, the NYSE standards as applicable to foreign private issuers and the 10 Principles of Corporate Governance of the Luxembourg Stock Exchange. The Audit & Risk Committee makes decisions by a simple majority with no member having a casting vote.

The Audit & Risk Committee currently consists of 4 members: Mrs. Karyn Ovelmen, Mrs. Patricia Barbizet, Mr. Karel de Gucht and Mr. Etienne Schneider, each of whom is an independent Director according to the NYSE standards and the 10 Principles of Corporate Governance of the Luxembourg Stock Exchange. The Chairwoman of the Audit & Risk Committee is Mrs. Patricia Barbizet who is an "audit committee financial expert" as defined by the SEC. Please see "—–Directors and senior management—–Board of Directors" above for Mrs. Barbizet's experience.

According to its charter, the Audit & Risk Committee is required to meet at least four times a year. The Audit & Risk Committee performs an annual self-evaluation and completed its 2024 self-evaluation on February 5, 2025. The charter of the Audit & Risk Committee is available from ArcelorMittal upon request.

Appointments, Remuneration and Corporate Governance Committee

In 2024, 7 meetings of the ARCG Committee were held, with an attendance rate of 100%.

The ARCG Committee is comprised of three directors, each of whom is independent under the New York Stock Exchange standards as applicable to foreign private issuers and the 10 Principles of Corporate Governance of the Luxembourg Stock Exchange.

The members are appointed by the Board of Directors each year after the annual general meeting of shareholders. The

ARCG Committee makes decisions by a simple majority with no member having a casting vote.

The primary function of the ARCG Committee is to assist the Board of Directors of ArcelorMittal by:

• reviewing and approving corporate and personal goals and objectives relevant to the compensation of members of the Executive Office, executive officers and senior management and evaluating their performance considering these goals and objectives;
• making recommendations to the Board of Directors on the Company`s framework of remuneration for the members of the Executive Office and executive officers and such other senior executives as the ARCG Committee may determine;

Succession management

Succession management at ArcelorMittal is a systematic, structured process for identifying and preparing employees with potential to fill key organizational positions, should the position become vacant. This process applies to all ArcelorMittal key positions up to and including the Executive Office. Succession management aims to ensure the continued effective performance of the organization by providing for the availability of experienced and capable employees who are prepared to assume these roles as they become available. For each position, candidates are identified based on performance, potential and an assessment of leadership capabilities and their "years to readiness". Development needs linked to the succession plans are discussed, after which "Personal Development Plans" are put in place, to accelerate development and prepare candidates. Regular reviews of succession plans are conducted at different levels of the organization to ensure that they are accurate and up to date,

leading to at least once a year formal review by the Executive Office, of all key positions. Succession management is a necessary process to reduce risk of vacant positions or skill gap transitions, create a pipeline of future leaders, ensure smooth business continuity and improve employee motivation and engagement. This process has been in place for several years and reinforced, widened and made more systematic in all regions of the organization. The responsibility to review and approve succession plans and contingency plans at the highest level rests with the Board's ARCG Committee.

Insider Dealing Regulations

ArcelorMittal has adopted insider trading policies and procedures ("Insider Dealing Regulations" or "IDR") governing the purchase, sale, and other dispositions of its securities by directors, senior management, and employees that are reasonably designed to promote compliance with insider trading laws, rules and regulations and listing standards applicable to the Company. IDR are updated when necessary (most recently in January 2023) and training is conducted throughout the Group in relation to them. The IDR's most recent version was updated in light of the new Market Abuse Regulation. IDR are available on ArcelorMittal's website, www.arcelormittal.com.

The IDR apply to the worldwide operations of ArcelorMittal. The compliance and data protection officer of ArcelorMittal is also the IDR compliance officer and answers questions that members of senior management, the Board of Directors, or employees may have about the IDR's interpretation. The IDR compliance officer maintains a list of insiders as required by Regulation No 596/2014 of the European Parliament and the Council dated April 16, 2014 on market abuse or "MAR" and the Commission Implementing Regulation 2016/347 of 10 March 2016 laying down technical standards with regard to the precise format of insider lists and for updating insider lists in accordance with MAR. The IDR compliance officer may assist senior executives and directors with the filing of notices required by Luxembourg law to be filed with the Luxembourg financial regulator, the CSSF (Commission de Surveillance du Secteur Financier). Furthermore, the IDR compliance officer has the power to conduct investigations in connection with the application and enforcement of the IDR, in which any employee or member of senior management or of the Board of Directors is required to cooperate.

Selected new employees of ArcelorMittal are required to participate in a training course about the IDR upon joining ArcelorMittal and every three years thereafter. The individuals who must participate in the IDR training include the members of senior management, employees who work in finance, legal, sales, mergers and acquisitions and other areas that the Company may determine from time to time. In addition, ArcelorMittal's Code of Business Conduct contains a section on "Trading in the Securities of the Company" that emphasizes the prohibition to trade on the basis of inside information. An online interactive training tool based on the IDR is currently deployed across the group through ArcelorMittal's intranet, with the aim to enhance the staff's awareness of the risks of sanctions applicable to insider dealing. The importance of the IDR is again reiterated in the Group's internal Group Policies and Procedures Manual.

Memorandum of Understanding

The Memorandum of Understanding entered into in connection with the Mittal Steel acquisition of Arcelor, certain provisions of which expired in August 2009 and August 2011, is described under "Additional information—Material contracts —Memorandum of Understanding".

Agreements with Aperam SA post-Stainless Steel Spin-Off In connection with the spin-off of its stainless steel division into a separately focused company, Aperam SA ("Aperam"), which was completed on January 25, 2011, ArcelorMittal entered into several agreements with Aperam and/ or certain Aperam subsidiaries which are still in force: a purchasing services agreement for negotiation services from ArcelorMittal Purchasing (the "Purchasing Services Agreement") as well as certain commitments regarding cost-sharing in Brazil and

certain other ancillary arrangements governing the relationship between Aperam and ArcelorMittal following the spin-off, as well as certain agreements relating to financing.

The parties agreed to renew a limited number of services where expertise and bargaining power created value for each party. ArcelorMittal will continue to provide in 2025 (similar to 2024) certain services relating to areas including environmental and technical support.

In the area of research and development at the time of the spin-off, Aperam entered into a framework agreement with ArcelorMittal in 2011, and as amended in 2015 to establish a structure for future cooperation in relation to certain ongoing or new research and development programs. Currently, few but valuable research and development supports are implemented through this agreement. New exchanges about breakthrough technologies or possible technical developments interesting both companies were launched between 2021 and 2024 and are still ongoing.

In Europe, Aperam purchased most of its electricity and natural gas through energy supply contracts put in place for the period 2014-2020 through ArcelorMittal Energy SCA. Electricity and natural gas contracts were renewed in 2022 and for 2023 under similar terms and conditions. Electricity and natural gas supplies continued in 2024 under the new conditions described in several new contracts reflecting the supply practices throughout 2024; contracts were signed in December 2024 effective from January 1, 2024 till January 1, 2026, extendable by mutual agreement between the parties.

Regarding procurement, Aperam still relies on ArcelorMittal Europe S.A. for supplies and services in relation to the negotiation of certain contracts with global or large regional suppliers. The Purchasing Services Agreement entered into on January 25, 2011 has been renewed and remains in force in relation to the following key categories: operating materials (only hot strip mill), refractory materials, spare parts, sea freight, logistics, industrial products and support services (excluding industrial services). The Purchasing Services Agreement also permits Aperam to avail itself of the services and expertise of ArcelorMittal for certain capital expenditures.

Another commercial agreement in place between Aperam and ArcelorMittal Sourcing is effective since January 2020 for the sale of electrodes. Two specific IT service agreements are also in place with Aperam, for the use in Europe and Brazil of

Asset Reliability Maintenance Program ("ARMP") and for the use of the global wide area network (WAN).

Purchasing activities will continue to be provided to Aperam pursuant to existing contracts with ArcelorMittal entities that it has specifically elected to assume. In addition, since 2011, a services agreement has been concluded between ArcelorMittal Shared Service Center Europe Sp z.o.o. Sp.k. and Aperam for accounting services.

In connection with the spin-off, management also renegotiated an existing Brazilian cost-sharing agreement between ArcelorMittal Brasil and Aperam Inox América do Sul S.A., Aperam Inox Serviços Brasil Ltda., Aperam Inox Tubos Brasil Ltda. and Aperam Bioenergia Ltda. pursuant to which, ArcelorMittal Brasil continued to perform purchasing for the benefit of these Aperam's Brazilian subsidiaries, with costs being shared on the basis of cost allocation parameters agreed between the parties on a yearly basis.

Share Repurchase Agreement

The Significant Shareholder has entered into a share repurchase agreement with ArcelorMittal on February 12, 2021 (as amended from time to time), (the "Share Repurchase Agreement"), to sell each trading day on which ArcelorMittal has purchased shares under its 2021 share buyback programs (the "Programs") an equivalent number of shares, at the proportion of the then Significant Shareholder's stake in ArcelorMittal of issued and outstanding shares of ArcelorMittal, at the same price as the shares repurchased on the market. The effect of the Share Repurchase Agreement was to maintain the Significant Shareholder's voting rights in ArcelorMittal's issued share capital (net of treasury shares) at the then-current level, pursuant to the Programs.

ArcelorMittal announced the completion of five consecutive Programs during 2021 under the authorization given by the annual general meetings of shareholders held on June 13, 2020 and June 8, 2021. To maintain Significant Shareholder's current level of voting rights as per the Share Repurchase Agreement, in the context of five consecutive Programs, in totality the Company repurchased, 62.2 million shares from the Significant Shareholder for \$1,878 million.

To maintain Significant Shareholder's current level of voting rights as per the Share Repurchase Agreement, the Company repurchased 525,177 shares from the Significant Shareholder for \$16.2 million. On February 25, 2022, the Company announced the decision of the Significant Shareholder not to further participate to such program. Accordingly, the Share Repurchase Agreement was terminated with respect to this program.

Markets

ArcelorMittal shares are listed and traded (through a single order book) on the Euronext European markets (Paris and Amsterdam) (symbol "MT"), are admitted to trading on the Luxembourg Stock Exchange's regulated market and listed on the Official List of the Luxembourg Stock Exchange (symbol "MT") and are listed and traded on the Spanish Stock Exchanges (symbol "MTS"). In the United States, ArcelorMittal shares are listed and traded on the NYSE (symbol "MT").

Paying agents

The paying agent for shareholders who hold shares listed on the NYSE is Citibank and the paying agent for shareholders who hold shares listed on Euronext Amsterdam, Euronext Paris, and Luxembourg Stock Exchange is ABN AMRO.

New York Registry Shares

The Company does not have any American Depositary Receipts. As described under "Additional information— Memorandum and Articles of Association—Form and transfer of shares", the Company maintains a New York share register with Citibank, N.A. for its shares that trade on the NYSE. As of December 31, 2024, 58,562,475 shares (or approximately 6.87% of ArcelorMittal's total issued shares) were ArcelorMittal New York Registry Shares. Holders of ArcelorMittal New York Registry Shares do not pay fees to Citibank as a general matter, but do incur costs of up to \$5 per 100 shares for transactions that require canceling or issuing New York Registry Shares, such as cross-border trades where New York Registry Shares are cancelled in exchange for shares held in ArcelorMittal's European register, or vice-versa. Subject to certain conditions, Citibank reimburses the Company on an annual basis for expenses incurred by the Company in relation to the ongoing maintenance of the New York share facility (e.g., investor relations expenses, NYSE listing fees, etc.). In 2024, Citibank paid the Company \$293,881 in respect of reimbursements of expenses incurred by the Company in 2024.

Dividend distributions

Based on Luxembourg law and its Articles of Association, ArcelorMittal allocates at least five percent of its net profits to the creation of a reserve. This allocation ceases to be compulsory when the reserve reaches ten percent (10%) of its issued share capital, and becomes compulsory once again when the reserve falls below that percentage. Under Luxembourg law, the amount of any dividends paid to shareholders may not exceed the amount of the profits at the end of the last financial year plus any profits carried forward and any amounts drawn from reserves that are available for that purpose, less any losses carried forward and sums to be placed in reserve in accordance with Luxembourg law or the Articles of Association. A company may not pay dividends to shareholders when, on the closing date of the last financial year, the net assets are, or following the payment of such dividend would become, lower than the amount of the subscribed capital plus the reserves that may not be distributed by law or by virtue of the articles of association. ArcelorMittal's Articles of Association provide that the portion of annual net profit that remains unreserved is allocated as follows by the general meeting of shareholders upon the proposal of the Board of Directors:

• • a global amount is allocated to the Board of Directors by way of directors' fees ("tantièmes"). This amount may not be less than €1,000,000. In the event that the profits are insufficient, the amount of €1,000,000 shall be imputed in whole or in part to charges. The distribution of this amount among the members of the Board of Directors shall be effected in accordance with the Board of Directors' rules of procedure; and
• the balance is distributed as dividends to the shareholders or placed in the reserves or carried forward.

Interim dividends may be distributed under the conditions set forth in Luxembourg law by decision of the Board of Directors.

No interest is paid on dividends declared but not paid which are held by the Company on behalf of shareholders.

Following the achievement of the Group's net debt target, in February 2021, the Board approved a new capital return policy. See under "History and development of the Company— Other information—Capital return policy".

In February 2022, the Board of Directors recommended an increase of the base annual dividend to \$0.38/share, from \$0.30/share which was approved on May 4, 2022 at the annual general meeting of shareholders. The dividend amounted to \$332 million and was paid on June 10, 2022.

In February 2023, the Board of Directors recommended an increase of the base annual dividend from \$0.38/share to \$0.44/share, which was approved on May 2, 2023 at the annual general meeting of shareholders. The dividend amounted to \$369 million.

In February 2024, the Board of Directors recommended an increase of the base annual dividend to \$0.50/share (from

\$0.44/share paid in 2023), which was approved on April 30, 2024 at the annual general meeting of shareholders. The dividend amounted to \$393 million.

In February 2025, the Board of Directors recommended an increase of the base annual dividend to \$0.55/share (from \$0.50/share paid in 2024), subject to the approval of shareholders at the annual general meeting of shareholders in May 2025.

Purchases of equity securities by the issuer and affiliated purchasers

On May 5, 2023, the Company announced a share buyback program of up to 85 million shares to be completed by May 2025 (subject to market conditions) pursuant to the authorization of the AGM held on May 2, 2023 ("2023 buyback program"), which remains outstanding as of the date of this annual report. At December 31, 2024, ArcelorMittal had repurchased approximately 78.2 million shares representing approximately 92% of the current share buyback program for a total value of \$2.0 billion.

See "Introduction—History and development of the Company —Additional information".

As described in "Memorandum and Articles of Association", the maximum number of shares that may be acquired does not in any event exceed 10% of the Company's issued share capital. The maximum number of own shares that the Company may hold at any time directly or indirectly may not have the effect of reducing its net assets ("actif net") below the amount mentioned in paragraphs 1 and 2 of Article 461-272-1 of the Law.

See "Introduction—History and development of the Company—Additional information". As of December 31, 2024, the 2023 buyback program was not yet completed.

Share capital

As of December 31, 2024, the Company's issued share capital amounted to \$303 million, represented by 852,809,772 ordinary shares without nominal value. The Company's issued share capital changed as described below in 2022 and 2023.

Out of the total of 852,809,772 shares in issue, 84,263,150 shares were held in treasury by ArcelorMittal at December 31, 2024, representing 9.88% of its issued share capital.

The Company's authorized share capital, including the issued share capital, was \$395 million, represented by 1,111,418,599 ordinary shares without nominal value as of December 31, 2024. The Company's authorized share capital changed as described below in 2022 and 2023.

On May 19, 2023, upon mandatory conversion of the remaining 24,290,025 outstanding mandatorily convertible subordinated notes issued on May 18, 2020 and due May 18, 2023, ArcelorMittal delivered a total of 57,057,991 treasury shares (of which 9,396,120 to the Significant Shareholder). See note 11.2 to the consolidated financial statements.

In line with the authorization granted by the EGM of ArcelorMittal shareholders held on May 4, 2022 and May 2, 2023, the Board of Directors decided to keep the number of treasury shares within appropriate levels by cancelling:

(i) on January 14, 2022, 45 million treasury shares. As a result of this cancellation, ArcelorMittal had 937,809,772 shares in issue (compared to 982,809,772 before cancellation);

(ii) on May 18, 2022, 60 million treasury shares. As a result of this cancellation, ArcelorMittal had 877,809,772 shares in issue (compared to 937,809,772 before cancellation); and

(iii) on April 28, 2023, 25 million treasury shares. As a result of such cancellation, ArcelorMittal has 852,809,772 shares in issue (compared to 877,809,772 before the cancellation).

The cancellations took into account the \$1 billion share buyback announced on November 17, 2021, which was completed on December 28, 2021, the \$1 billion share buyback announced on May 5, 2022, which was completed on June 8, 2022 and the 60,431,380 share buyback announced on July 29, 2022 which was completed on March 31, 2023.

Over the years, ArcelorMittal has issued equity-settled sharebased payments to certain employees, including stock options, restricted share units and performance share units. See note 8.3 to the consolidated financial statements.

ADDITIONAL INFORMATION

Memorandum and Articles of Association

Below is a summary of ArcelorMittal's Articles of Association and certain legal provisions and internal policies applicable to ArcelorMittal. The full text of the Company's Articles of Association is also available on www.arcelormittal.com under "Investors-Corporate Governance-Current-Articles of Association".

Corporate purpose

Article 3 of the Articles of Association provides that the corporate purpose of ArcelorMittal is the manufacture, processing and marketing of steel, steel products and all other metallurgical products, as well as all products and materials used in their manufacture, their processing and their marketing, and all industrial and commercial activities connected directly or indirectly with those objects, including mining and research activities and the creation, acquisition, holding, exploitation and sale of patents, licenses, know-how and, more generally, intellectual and industrial property rights.

The Company may realize its corporate purpose either directly or through the creation of companies, the acquisition, holding or acquisition of interests in any companies or partnerships, membership in any associations, consortia and joint ventures.

In general, the Company's corporate purpose comprises the participation, in any form whatsoever, in companies and partnerships and the acquisition by purchase, subscription or in any other manner as well as the transfer by sale, exchange or in any other manner of shares, bonds, debt securities, warrants and other securities and instruments of any kind.

It may grant assistance to any affiliated company and take any measure for the control and supervision of such companies.

It may carry out any commercial, financial or industrial operation or transaction that it considers to be directly or indirectly necessary or useful in order to achieve or further its corporate purpose.

Form and transfer of shares

The shares of ArcelorMittal are issued in registered form only and are freely transferable. There are no restrictions on the rights of Luxembourg or non-Luxembourg residents to own ArcelorMittal shares.

In accordance with Luxembourg law, the ownership of registered shares is evidenced by the inscription of the name of the shareholder and the number of shares held by such shareholder in the shareholders' register. Each transfer of shares is made by a written declaration of transfer recorded in the shareholders' register of ArcelorMittal, dated and signed by the transferor and the transferee or by their duly appointed agent. ArcelorMittal may accept and enter into its shareholders' register any transfer based on an agreement between the transferor and the transferee provided a true and complete copy of such agreement is provided to ArcelorMittal.

The Articles of Association provide that shares may be held through a securities settlement (clearing) system or a professional depositary of securities. Shares held in this manner have the same rights and obligations as the registered shares. Shares held through a securities settlement system or a professional depositary of securities may be transferred in accordance with customary procedures for the transfer of securities in book-entry form.

The ArcelorMittal ordinary shares may be held in registered form on the Company's register only. Registered shares are fully fungible and may consist of:

• a ArcelorMittal Registry Shares, which are registered directly on ArcelorMittal's Luxembourg shareholders' register,
• b shares traded on Euronext Amsterdam, Euronext Paris, the regulated market of the Luxembourg Stock Exchange and the Spanish Stock Exchanges, which are held in Euroclear, or
• c shares traded on the NYSE (the "New York Registry Shares"), which are registered (including in the name of the nominee of DTC) in a New York Share Register kept on behalf of ArcelorMittal by Citibank, N.A., its New York transfer agent.

ABN AMRO assists the Company with certain administrative tasks relating to the day-to-day administrative management of the shareholders' register. The Company maintains a New York shareholders' register with Citibank, N.A. (located at 388 Greenwich Street, New York, New York 10013) for its New York Registry Shares that trade on the NYSE with underlying positions held in Euroclear. As of December 31, 2024, 58,562,475 shares (or approximately 6.87% of ArcelorMittal's total issued shares) were New York Registry Shares.

The law of April 6, 2013 concerning dematerialized securities allows Luxembourg issuers to opt for the full dematerialization of shares. The EGM of ArcelorMittal shareholders held on May 10, 2017 authorized and empowered the Board of Directors to give effect to such dematerialization and to determine its effective date, following which new shares in the Company may only be issued in dematerialized form (the "Effective Date"). Notice of the compulsory dematerialization will be given in accordance with Article 6.9 (i) of the Articles of Association. As from the Effective Date, shareholders would be required to hold their shares in a securities account at a bank or other financial intermediary, which would in turn hold the shares via an account with a securities depository such as Clearstream or Euroclear. Dematerialized securities would be solely represented by account entries with the securities depositary and would therefore exist only in electronic form. It would then no longer be possible for shareholders to hold shares through a direct, nominative registration in the Company's register of shareholders as is currently the case. As of December 31, 2024, notice of the Effective Date has not been given.

Issuance of shares

The issuance of shares by ArcelorMittal requires either an amendment of the Articles of Association approved by an EGM or a decision of the Board of Directors that is within the limits of the authorized share capital set out in the Articles of Association. In the latter case, the Board of Directors may determine the conditions for the issuance of shares, including the consideration (cash or in kind) payable for such shares.

The EGM may not validly deliberate unless at least half of the share capital is present or represented upon the first call. If the quorum is not met, the meeting may be reconvened as described in "General meeting of shareholders" below. The second meeting will be held regardless of the proportion of share capital represented. At both meetings, resolutions, in order to be adopted, must be carried by at least two-thirds of the votes cast.

Preemptive rights

Unless limited or canceled by the Board of Directors as described below or by an EGM, holders of ArcelorMittal shares have a pro rata preemptive right to subscribe for newly issued shares, except for shares issued for consideration other than cash (i.e., in kind).

The Articles of Association provide that preemptive rights may be limited or canceled by the Board of Directors in the event of an increase in the Company's issued share capital until the date being five years from the date of publication in the Luxembourg legal gazette (Recueil électronique des sociétés et associations) ("RESA") of the relevant meeting minutes, which publication occurred on June 17, 2020 with respect to the minutes of the EGM held on June 13, 2020. This power of the Board of Directors may be renewed from time to time by an EGM for subsequent periods not to exceed five years each.

Repurchase of shares

ArcelorMittal is prohibited by Luxembourg law from subscribing for its own shares. ArcelorMittal may, however, repurchase its own shares or have another person repurchase shares on its behalf, subject to certain conditions, including:

• a prior authorization of the general meeting of shareholders setting out the terms and conditions of the proposed repurchase, including the maximum number of shares to be repurchased, the duration of the period for which the authorization is given (which may not exceed five years) and the minimum and maximum consideration per share;
• the repurchase may not reduce the net assets of ArcelorMittal on a non-consolidated basis to a level below the aggregate of the issued share capital and the reserves that ArcelorMittal must maintain pursuant to Luxembourg law or its Articles of Association;
• only fully paid-up shares may be repurchased. At December 31, 2024, all of ArcelorMittal's issued ordinary shares were fully paid-up; and
• the acquisition offer is made on the same terms and conditions to all the shareholders who are in the same position, it being noted however that listed companies may repurchase their own shares on the stock exchange without an acquisition offer having to be made to the shareholders.

In addition, Luxembourg law allows the Board of Directors to approve the repurchase of ArcelorMittal shares without the

prior approval of the general meeting of shareholders if necessary to prevent serious and imminent harm to ArcelorMittal. In such a case, the next general meeting of shareholders must be informed by the Board of Directors of the reasons for and the purpose of the acquisitions made, the number and nominal values, or in the absence thereof, the accounting par value of the shares acquired, the proportion of the issued share capital that they represent, and the consideration paid for them.

The annual general meeting of shareholders held on April 30, 2024 (the "2024 AGM") decided to authorize, effective immediately after the 2024 AGM, the Board of Directors, with the option to delegate to the corporate bodies of the other companies in the ArcelorMittal group in accordance with the Luxembourg law of August 10, 1915 on commercial companies, as amended (the "Law"), to acquire and sell shares in the Company in accordance with the Law and any other applicable laws and regulations, including but not limited to entering into off-market and over-the-counter transactions and to acquire shares in the Company through derivative financial instruments as well as to enter into cash-settled derivative financial instruments to mitigate the volatility in the share prices paid to acquire shares in the Company (the "Authorization").

Any acquisitions, disposals, exchanges, contributions or transfers of shares by the Company or other companies in the ArcelorMittal group must be in accordance with Regulation (EU) No. 596/2014 of the European Parliament and of the Council of April 16, 2014 on market abuse (the "MAR Regulation"), Commission Delegated Regulation (EU) No. 2016/1052 of March 8, 2016 with regard to regulatory technical standards for the conditions applicable to buy-back programs and stabilization measures and Luxembourg law of December 23, 2016 on market abuse implementing the MAR Regulation.

Such transactions may be carried out at any time, including during a tender offer period, subject to applicable laws and regulations including Section 10(b) and Section 9(a)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5 promulgated under the Exchange Act.

The Authorization is valid until the end of the annual general meeting of shareholders to be held in 2027 (the "2027 AGM") or until the date of its renewal by a resolution of the general meeting of shareholders if such renewal date is prior to the expiration of the 2027 AGM.

The Company may not repurchase shares amounting to more than 10% of its issued share capital (at the date of the 2024 AGM being 85,280,977 shares). The maximum number of own shares that the Company may hold at any time directly or indirectly may not have the effect of reducing its net assets ("actif net") below the amount mentioned in paragraphs 1 and 2 of Article 461-2 of the Law. The purchase price per share to be paid shall not exceed 110% of the average of the final

listing prices of the 30 trading days preceding the three trading days prior to each date of repurchase, and shall not be less than one euro cent. The final listing prices are those on the NYSE, Euronext markets or the Luxembourg Stock Exchange, depending on the market on which the purchases are made. For off-market transactions, the maximum purchase price shall be 110% of the reference price on the NYSE (in case of purchase in USD) or the Euronext markets (in case of purchase in EUR) on which the Company's shares are listed. The reference price will be deemed to be the average of the final listing prices per share on these markets during 30 consecutive days on which these markets are open for trading preceding the three trading days prior to the date of purchase. For the avoidance of doubt, price restrictions set out in the immediately preceding paragraphs do not apply to cashsettled derivative financial instruments entered into to mitigate volatility in the per share prices paid to acquire shares in the Company. In the event of a share capital increase by incorporation of reserves or issue premiums and the free allotment of shares as well as in the event of the division or regrouping of the shares, the purchase price indicated above shall be adjusted by a multiplying coefficient equal to the ratio between the number of shares comprising the issued share capital prior to the transaction and such number following the transaction.

Capital reduction

The Articles of Association provide that the issued share capital of ArcelorMittal may be reduced subject to the approval of at least two-thirds of the votes cast at an extraordinary general meeting of shareholders where, at first call, at least 50% of the issued share capital is required to be represented, with no quorum being required at a reconvened meeting.

The extraordinary general meeting of shareholders held on May 2, 2023 decided to authorize the Board of Directors, for a period of three years (i) to cancel all the shares repurchased by the Company under its share buyback programs up to a maximum of 88 million shares and to consequently reduce the issued share capital of the Company and the authorized share capital of the Company by an amount corresponding to the product of the number of treasury shares cancelled multiplied by thirty-six U.S. dollar cents (USD 0.36), being the par value of the shares in the Company - and (ii) to consequentially amend articles 5.1 and 5.2 of the articles of association of the Company to reflect the above cancellations and reductions of the issued and authorized share capital of the Company, (iii) to reduce or cancel the relevant reserves constituted under applicable law in relation thereto and (iv) to instruct and delegate power to and authorize the Board of Directors or its delegate(s) to implement the cancellation of the number of treasury shares determined by the Board of Directors and the corresponding reduction of share capital and related matters in one or more installments as deemed fit by the Board of Directors, to cause the share capital reductions and cancellations of the treasury shares and the consequential amendment of the Articles to be recorded by way of one or

more notarial deeds, and generally to take any steps, actions or formalities as appropriate or useful to implement this decision of the extraordinary general meeting.

Please refer to the section on "Shareholder and markets - Share capital" for the details on the latest share capital reductions.

General meeting of shareholders

The shareholders' rights law of May 24, 2011, which transposes into Luxembourg law Directive 2007/36/EC of the European Parliament and of the Council of July 11, 2007 (on the exercise of certain rights of shareholders in listed companies) as amended (the "Shareholders' Rights Law") includes provisions relating to general meetings of shareholders, as discussed below.

General meetings of shareholders are convened by the publication of a notice at least 30 days before the meeting date in a Luxembourg newspaper, via the online platform called Recueil électronique des sociétés et associations ("RESA"), and by way of press release sent to the major news agencies. Ordinary general meetings are not subject to any minimum shareholder participation level. Extraordinary general meetings, however, are subject to a minimum quorum of 50% of the share capital. In the event the 50% quorum is not met upon the first call, the meeting may be reconvened by way of convening notice published in the same manner as the first notice, at least 17 days before the meeting date. No quorum is required upon the second call.

Shareholders whose share ownership is directly registered in the shareholders' register of the Company must receive the convening notice by regular mail, unless they have accepted to receive it through other means (i.e., electronically). In addition, all materials relating to a general meeting of shareholders must be made available on the website of ArcelorMittal from the first date of publication of the convening notice.

The Shareholders' Rights Law abolished the blocking period and introduced the record date system into Luxembourg law. As set out in the Articles of Association, the record date applicable to ArcelorMittal is the 14th day at midnight before the general meeting date. Only the votes of shareholders who are shareholders of the Company on the record date will be taken into account, regardless of whether they remain shareholders on the general meeting date. Shareholders who intend to participate in the general meeting must notify the Company at the latest on the date indicated in the convening notice of their intention to participate (by proxy or in person).

Ordinary general meetings of shareholders.

At an ordinary general meeting of shareholders there is no quorum requirement and resolutions are adopted by a simple majority, irrespective of the number of shares represented. Ordinary general meetings deliberate on any matter that does not require the convening of an extraordinary general meeting. The Articles of Association provide that the annual general meeting of shareholders is held each year within six months from the end of the previous financial year at the Company's registered office or at any other place in the Grand Duchy of Luxembourg as determined by the Board of Directors and indicated in the convening notice.

Extraordinary general meetings of shareholders. An extraordinary general meeting must be convened to deliberate on the following types of matters:

• an increase or decrease of the authorized or issued share capital,
• a limitation or exclusion of existing shareholders' preemptive rights,
• the acquisition by any person of 25% or more of the issued share capital of ArcelorMittal,
• approving a merger or similar transaction such as a spinoff, and
• any transaction or matter requiring an amendment of the Articles of Association.

The extraordinary general meeting must reach a quorum of shares present or represented at the meeting of 50% of the share capital in order to validly deliberate. If this quorum is not reached, the meeting may be reconvened and the second meeting will not be subject to any quorum requirement. In order to be adopted by the extraordinary general meeting (on the first or the second call), any resolution submitted must be approved by at least two-thirds of the votes cast except for certain limited matters where the Articles of Association require a higher majority (see "—Amendment of the Articles of Association"). Votes cast do not include votes attaching to shares with respect to which the shareholder has not taken part in the vote, has abstained or has returned a blank or invalid vote.

In addition, Luxembourg law requires the Board of Directors to convene a general meeting of shareholders if shareholders representing in the aggregate 10% of the issued share capital so require in writing with an indication of the requested agenda. In this case, the general meeting of shareholders must be held within one month of the request. If the requested general meeting of shareholders is not so convened, the relevant shareholder or group of shareholders may petition the competent court in Luxembourg to have a court appointee convene the general meeting.

Shareholder participation at general meetings

The Board of Directors may decide to arrange for shareholders to be able to participate in the general meeting by electronic means by way, among others, of (i) real-time transmission to the public of the general meeting, (ii) two-way communication enabling shareholders to address the general meeting from a remote location, or (iii) a mechanism allowing duly identified shareholders to cast their votes before or during the general meeting without the need for them to appoint a proxyholder who would be physically present at the meeting.

A shareholder may act at any general meeting of shareholders by appointing another person (who need not be a shareholder) as his or her attorney by means of a written proxy using the form made available on the website of the Company. The completed and signed proxy must be sent to the Company in accordance with the instructions set out in the convening notice.

The Board of Directors may also decide to allow shareholders to vote by correspondence by means of a form providing for a positive or negative vote or an abstention on each agenda item. The conditions for voting by correspondence are set out in the Articles of Association and in the convening notice.

Shareholders representing in the aggregate 5% of the issued share capital may also request that additional items be added to the agenda of a general meeting and may draft alternative resolutions to be submitted to the general meeting regarding existing agenda items. The request must be made in writing and sent either to the electronic address or to the Company's postal address set out in the convening notice.

The Shareholders' Rights Law provides that a company's articles of association may allow shareholders to ask questions prior to the general meeting which will be answered by management during the general meeting's questions and answers session prior to the vote on the agenda items. Although the Articles of Association do not specifically address this point, shareholders may ask questions in writing ahead of a general meeting, which are taken into account in preparing the general meeting's questions and answers session. With regard to the April 30, 2024 general meetings, shareholders could also send questions to the Company in advance by writing to a dedicated e-mail address indicated in the convening notice. The Company on a best efforts basis provided responses to the questions during the general meeting Q&A session.

Identification of shareholders

Pursuant to the Shareholders' Rights Law, listed companies now have the ability to identify their shareholders and ultimately improve communication between them and their shareholders. Intermediaries, including those in third countries, are required to provide the Company with information to enable the identification of shareholders. Intermediaries in-scope of the Shareholders' Rights Law are investment firms, credit institutions and central securities depositories which provide share safekeeping or administration of securities accounts or maintenance services to shareholders or other persons. Third country in-scope intermediaries are those which provide these services to shareholders or other intermediaries with respect to shares in the Company and are located outside of the European Union. There are no restrictions on the rights of Luxembourg or non-Luxembourg residents to vote ArcelorMittal shares. Each share entitles the shareholder to attend a general meeting of shareholders in person or by proxy, to address the general meeting of shareholders and to vote. Each share entitles the holder to one vote at the general meeting of shareholders. There is no minimum shareholding (beyond owning a single share or representing the owner of a single share) required to be able to attend or vote at a general meeting of shareholders.

The voting and information rights of ArcelorMittal's shareholders have been further expanded since the entry into force of the Shareholders' Rights Law.

Election and removal of directors

Members of the Board of Directors are elected by simple majority of the represented shareholders at an ordinary general meeting of shareholders. Directors are elected for a period ending on a date determined at the time of their appointment. The directors of ArcelorMittal are elected for three-year terms in staggered intervals. Any director may be removed with or without cause by a simple majority vote at any general meeting of shareholders.

(a) a director's power to vote on a proposal, arrangement or contract in which the director is materially interested; If a Director has directly or indirectly a financial interest in a transaction that is submitted to the Board of Directors for approval and this interest conflicts with that of ArcelorMittal (other than transactions which are ordinary business operations and are entered into under normal conditions), the Director must advise the Board of Directors of the existence and nature of the conflict and cause a record of his/her statement to be included in the minutes of the meeting. In addition, the Director may not take part in the discussions on and may not vote on the relevant transaction and he or she shall not be counted for the purposes of whether the quorum is present, in which case the Board of Directors may validly deliberate if at least the majority of the non-conflicted directors are present or represented. At the next following general meeting of shareholders of ArcelorMittal, before any other resolution is put to a vote, a special report will be made by the Board of Directors to the shareholders' meeting on any such transaction.

If a material transaction with a related party involves a Director, that Director may not participate in the approval of such transaction.

(b) the directors' power, in the absence of an independent quorum, to vote compensation to themselves or any members of their body;

The remuneration of the Directors is determined each year by the annual general meeting of shareholders subject to Article 17 of the Articles of Association. The annual shareholders meeting of the Company decides on the directors' remuneration. The Executive Chairman is not remunerated for his membership on the Board of Directors. The remuneration

Voting and information rights

of the Executive Chairman is determined by the Board's ARCG Committee, which consists solely of independent directors. For more information, see "Management and employees—Compensation".

Pursuant to the Shareholders' Rights Law, the shareholders must be informed in detail of the remuneration of the members of the Company's Board of Directors and its CEO and the company's remuneration policy. Companies must prepare a management remuneration policy describing all components, criteria, methods and modalities applied to determine the fixed and variable remuneration of such persons. Such remuneration policy must contribute to the Company' business strategy and long-term interests. It must be resubmitted to an advisory vote at the general meeting of shareholders for approval each time there is a significant change thereto and at least every four years. In addition, companies must prepare a remuneration report for the annual general meeting on the remuneration and benefits granted to directors, and such remuneration report is required to be submitted for an advisory vote at the general meeting of shareholders each year.

(c) borrowing powers exercisable by the directors and how such borrowing powers can be varied;

Any transaction between ArcelorMittal or a subsidiary of ArcelorMittal and a Director (or an affiliate of a Director) must be conducted on arm's length terms and, if material, must obtain the approval of the Independent Directors.

(d) retirement or non-retirement of directors under an age limit requirement

There is no retirement or non-retirement of directors under an age limit requirement. However, on October 30, 2012, the Board of Directors adopted a policy that places limitations on the terms of independent directors as well as the number of directorships Directors may hold in order to align the Company's corporate governance practices with best practices in this area. The policy provides that an independent director may not serve on the Board of Directors for more than 12 consecutive years, although the Board of Directors may, by way of exception to this rule, make an affirmative determination, on a case-by-case basis, that he or she may continue to serve beyond the 12 years rule if the Board of Directors considers it to be in the best interest of the Company based on the contribution of the Director involved and the balance between the knowledge, skills, experience and need for renewal of the Board.

(e) number of shares, if any, required for director's qualification.

Article 8.2 of the Articles of Association states that the members of the Board of Directors do not have to be shareholders in the Company. However, the Board of Directors introduced on October 30, 2012 (as amended on November 7, 2017) a policy that requires members of the Board of Directors to hold 4,000 shares in the Company (6,000 for the Lead Independent Director). For more information, see

"Management and employees—Corporate governance— Specific characteristics of the director role".

ArcelorMittal's Articles of Association provide that the Significant Shareholder is entitled to nominate a number of candidates for election by the shareholders to the Board of Directors in proportion to its shareholding. The Significant Shareholder has not exercised this right to date.

Amendment of the Articles of Association

Any amendments to the Articles of Association must be approved by an extraordinary general meeting of shareholders held in the presence of a Luxembourg notary, followed by the publications required by Luxembourg law.

In order to be adopted, amendments of the Articles of Association relating to the size and the requisite minimum number of independent and non-executive directors of the Board of Directors, the composition of the Audit & Risk Committee, and the nomination rights to the Board of Directors of the Significant Shareholder require a majority of votes representing two-thirds of the voting rights attached to the shares in ArcelorMittal. The same majority rule would apply to amendments of the provisions of the Articles of Association that set out the foregoing rule.

Annual accounts

Each year before submission to the annual ordinary general meeting of shareholders, the Board of Directors approves the stand-alone audited financial statements for ArcelorMittal, the parent company of the ArcelorMittal group as well as the consolidated financial statements of the ArcelorMittal group, each of which are prepared in accordance with IFRS. The Board of Directors also approves the management reports on each of the stand-alone audited financial statements and the consolidated financial statements, and in respect of each of these sets of accounts a report must be issued by the independent auditors.

The stand-alone audited financial statements, the consolidated financial statements, the management reports and the auditor's reports will be available on request from the Company and on the Company's website from the date of publication of the convening notice for the annual ordinary general meeting of shareholders.

The stand-alone audited financial statements and the consolidated financial statements, after their approval by the annual ordinary general meeting of shareholders, are filed with the Luxembourg Register of Commerce and Companies.

Dividends

Except for shares held in treasury by the Company, each ArcelorMittal share is entitled to participate equally in dividends if and when declared out of funds legally available for such purposes. The Articles of Association provide that the annual ordinary general meeting of shareholders may declare a dividend and that the Board of Directors may declare interim dividends within the limits set by Luxembourg law.

Declared and unpaid dividends held by ArcelorMittal for the account of its shareholders do not bear interest. Under Luxembourg law, claims for dividends lapse in favor of ArcelorMittal five years after the date on which the dividends have been declared.

Merger and division

A merger whereby the Luxembourg company being acquired transfers to an existing or newly incorporated Luxembourg company all of its assets and liabilities in exchange for the issuance to the shareholders of the company being acquired of shares in the acquiring company, and a division whereby a company (the company being divided) transfers all its assets and liabilities to two or more existing or newly incorporated companies in exchange for the issuance of shares in the beneficiary companies to the shareholders of the company being divided or to such company, and certain similar restructurings must be approved by an extraordinary general meeting of shareholders of the relevant companies held in the presence of a notary. These transactions require the approval of at least two-thirds of the votes cast at a general meeting of shareholders of each of the companies where at least 50% of the share capital is represented upon first call, with no such quorum being required at a reconvened meeting.

Liquidation

In the event of the liquidation, dissolution or winding-up of ArcelorMittal, the assets remaining after allowing for the payment of all liabilities will be paid out to the shareholders pro rata to their respective shareholdings. The decision to liquidate, dissolve or wind-up the Company requires the approval of at least two-thirds of the votes cast at a general meeting of shareholders where at first call at least 50% of the share capital is represented, with no quorum being required at a reconvened meeting. Irrespective of whether the liquidation is subject to a vote at the first or a subsequent extraordinary general meeting of shareholders, it requires the approval of at least two-thirds of the votes cast at the extraordinary general meeting of shareholders.

Mandatory bid—squeeze-out right—sell-out right

Mandatory bid. The Luxembourg law of May 19, 2006 implementing Directive 2004/25/EC of the European Parliament and the Council of April 21, 2004 on takeover bids, as amended from time to time (the "Takeover Law"), provides that, if a person acting alone or in concert acquires securities of ArcelorMittal which, when added to any existing holdings of ArcelorMittal securities, give such person voting rights representing at least one third of all of the voting rights attached to the issued shares in ArcelorMittal, this person is obliged to make an offer for the remaining shares in ArcelorMittal. In a mandatory bid situation the "fair price" is in principle considered to be the highest price paid by the offeror or a person acting in concert with the offeror for the securities during the 12–month period preceding the mandatory bid.

ArcelorMittal's Articles of Association provide that any person who acquires shares giving them 25% or more of the total

voting rights of ArcelorMittal must make or cause to be made, in each country where ArcelorMittal's securities are admitted to trading on a regulated or other market and in each of the countries in which ArcelorMittal has made a public offering of its shares, an unconditional public offer of acquisition for cash to all shareholders for all of their shares and also to all holders of securities giving access to capital or linked to capital or whose rights are dependent on the profits of ArcelorMittal. The price offered must be fair and equitable and must be based on a report drawn up by a leading international financial institution nominated by the Company.

Squeeze-out right. The Takeover Law provides that, when an offer (mandatory or voluntary) is made to all of the holders of voting securities of ArcelorMittal and if after such offer the offeror holds at least 95% of the securities carrying voting rights and 95% of the voting rights, the offeror may require the holders of the remaining securities to sell those securities (of the same class) to the offeror. The price offered for such securities must be a fair price. The price offered in a voluntary offer would be presumed a fair price in the squeeze-out proceedings if the offeror acquired at least 90% of the ArcelorMittal shares carrying voting rights that were the subject of the offer. The price paid in a mandatory offer is presumed a fair price. The consideration paid in the squeezeout proceedings must take the same form as the consideration offered in the offer or consist solely of cash. Moreover, an allcash option must be offered to the remaining ArcelorMittal shareholders. Finally, the right to initiate squeeze-out proceedings must be exercised within three months following the expiration of the offer.

Sell-out right. The Takeover Law provides that, when an offer (mandatory or voluntary) is made to all of the holders of voting securities of ArcelorMittal and if after such offer the offeror holds securities carrying more than 90% of the voting rights, the remaining security holders may require that the offeror purchase the remaining securities of the same class. The price offered in a voluntary offer would be presumed "fair" in the sell-out proceedings if the offeror acquired at least 90% of the ArcelorMittal shares carrying voting rights and which were the subject of the offer. The price paid in a mandatory offer is presumed to be a fair price. The consideration paid in the sellout proceedings must take the same form as the consideration offered in the offer or consist solely of cash. Moreover, an allcash option must be offered to the remaining ArcelorMittal shareholders. Finally, the right to initiate sell-out proceedings must be exercised within three months following the expiration of the offer.

Disclosure of significant ownership in ArcelorMittal shares Holders of ArcelorMittal shares and derivatives or other financial instruments linked to ArcelorMittal shares may be subject to the notification obligations of the Luxembourg law of January 11, 2008, as amended, on transparency requirements regarding information about issuers whose securities are admitted to trading on a regulated market (the "Transparency

Law"). The following description summarizes these obligations. ArcelorMittal shareholders are advised to consult with their own legal advisers to determine whether the notification obligations apply to them.

The Transparency Law provides that, if a person acquires or disposes of a shareholding in ArcelorMittal, and if following the acquisition or disposal the proportion of voting rights held by the person reaches, exceeds or falls below one of the thresholds of 5%, 10%, 15%, 20%, 25%, one-third, 50% or two-thirds of the total voting rights existing when the situation giving rise to a declaration occurs, the relevant person must simultaneously notify ArcelorMittal and the CSSF (the Luxembourg securities regulator) of the proportion of voting rights held by it further to such event within four Luxembourg Stock Exchange trading days of the day of execution of the transaction triggering the threshold crossing.

A person must also notify ArcelorMittal of the proportion of his or her voting rights if that proportion reaches, exceeds or falls below the above-mentioned thresholds as a result of events changing the breakdown of voting rights.

The above notification obligations also apply to persons who directly or indirectly hold financial instruments linked to ArcelorMittal shares. Pursuant to article 12 a. of the Transparency Law, persons who hold ArcelorMittal shares and financial instruments linked to ArcelorMittal shares must aggregate their holding.

ArcelorMittal's Articles of Association also provide that the above disclosure obligations also apply to:

• any acquisition or disposal of shares resulting in the threshold of 2.5% of voting rights in ArcelorMittal being crossed upwards or downwards,
• any acquisition or disposal of shares resulting in the threshold of 3.0% of voting rights in ArcelorMittal being crossed upwards or downwards, and
• with respect to any shareholder holding at least 3.0% of the voting rights in ArcelorMittal, to any acquisition or disposal of shares resulting in successive thresholds of 1.0% of voting rights being crossed upwards or downwards.

Pursuant to the Articles of Association, any person who acquires shares giving him or her 5% or more or a multiple of 5% or more of the voting rights must inform ArcelorMittal within 10 Luxembourg Stock Exchange trading days following the date on which the threshold was crossed by registered letter with return receipt requested as to whether he or she intends to acquire or dispose of shares in ArcelorMittal within the next 12 months or intends to seek to obtain control over ArcelorMittal or to appoint a member to ArcelorMittal's Board of Directors.

The sanction of suspension of voting rights automatically applies, subject to limited exceptions set out in the Transparency Law, to any shareholder (or group of shareholders) who has (or have) crossed the thresholds set out in article 7 of the Articles of Association and articles 8 to 15 of the Transparency Law but have not notified the Company accordingly. The sanction of suspension of voting rights will apply until such time as the notification has been properly made by the relevant shareholder(s).

For the purposes of calculating the percentage of a shareholder's voting rights in ArcelorMittal, the following are taken into account:

• voting rights held by a third party with whom that person or entity has concluded an agreement and which obliges them to adopt, by concerted exercise of the voting rights they hold, a lasting common policy towards ArcelorMittal;
• voting rights held by a third party under an agreement concluded with that person or entity providing for the temporary transfer for consideration of the voting rights in question;
• voting rights attaching to shares pledged as collateral with that person or entity, provided the person or entity controls the voting rights and declares its intention to exercise them;
• voting rights attaching to shares in which a person or entity holds a life interest;
• voting rights which are held or may be exercised within the meaning of the four foregoing points by an undertaking controlled by that person or entity;
• voting rights attaching to shares deposited with that person or entity which the person or entity may exercise at its discretion in the absence of specific instructions from the shareholders;
• voting rights held by a third party in its own name on behalf of that person or entity; and
• voting rights which that person or entity may exercise as a proxy where the person or entity may exercise the voting rights in its sole discretion.

In addition, the Articles of Association provide that, for the purposes of calculating a person's voting rights in ArcelorMittal, the voting rights attached to shares underlying any other financial instruments owned by that person (such as convertible notes) must be taken into account for purposes of the calculation described above.

Disclosure of insider dealing transactions Members of the Board of Directors and the members of the Executive Office, Executive Officers and other executives fulfilling senior management responsibilities within

ArcelorMittal and falling with the definition of "Persons Discharging Senior Managerial Responsibilities" set out below and persons closely associated with them must disclose to the CSSF and to ArcelorMittal all transactions relating to shares or debt instruments of ArcelorMittal or derivatives or other financial instruments linked to any shares or debt instruments of ArcelorMittal (together the "Financial Instruments") conducted by them or for their account. Such notifications shall be made promptly and not later than three business days after the date of the transaction.

"Persons Discharging Senior Managerial Responsibilities" within ArcelorMittal are the members of the Board of Directors, and the Executive Office, the Executive Officers, and other executives occupying a high level management position with regular access to non-public material information relating, directly or indirectly, to ArcelorMittal and have the authority to make management decisions about the future development of the Company and its business strategy (see "Management and employees— Directors and senior management" for a description of senior management). Persons closely associated with them include their respective family members.

Both information on trading in Financial Instruments by "Persons Discharging Senior Managerial Responsibilities" and ArcelorMittal's Insider Dealing Regulations are available on www.arcelormittal.com under "Investors—Corporate Governance—Share Transactions by Management". For more information, see "Management and employees—Directors and senior management". In 2024, eight notifications were received by ArcelorMittal from such persons and filed with the CSSF.

Related Party Transactions

The Shareholders' Rights Law provides that a company is now required to publicly disclose material transactions (excluding "transactions taking place as part of the company's ordinary activity and concluded under normal market conditions") with related parties no later than at the time of conclusion of the transaction. The same requirement applies to material transactions concluded between related parties of a company and subsidiaries of such company. The Board of Directors must approve material transactions of the Company with related parties. A transaction with a related party is material if (i) its publication and divulgation may have a significant impact on the economic decisions of shareholders and (ii) it may create a risk for the company and its shareholders which are not related parties, including minority shareholders. In the determination of whether a transaction is material both the nature of the transaction and the position of the related party must be taken into account.

Publication of regulated information

Since January 2009, disclosure to the public of "regulated information" (within the meaning of the Luxembourg Transparency Law) concerning ArcelorMittal has been made by publishing the information through the centralized regulated information filing and storage system managed by the

Luxembourg Stock Exchange and accessible in English and French on www.luxse.com, in addition to the publication by ArcelorMittal of the information by way of press release. All news and press releases issued by the Company are available on www.arcelormittal.com in the "News and Media" section.

Limitation of directors' liability/indemnification of Directors and the members of the Executive Office

The Articles of Association provide that ArcelorMittal will, to the broadest extent permitted by Luxembourg law, indemnify every director and member of the Executive Office as well as every former director or member of the Executive Office for fees, costs and expenses reasonably incurred in the defense or resolution (including a settlement) of all legal actions or proceedings, whether civil, criminal or administrative, he or she has been involved in his or her role as former or current director or member of the Executive Office.

The right to indemnification does not exist in the case of gross negligence, fraud, fraudulent inducement, dishonesty or for a criminal offense, or if it is ultimately determined that the director or members of the Executive Office has not acted honestly, in good faith and with the reasonable belief that he or she was acting in the best interests of ArcelorMittal.

The Company also maintains liability insurance for its directors and officers, including insurance against liabilities arising under the U.S. Securities Act of 1933, as amended, and the U.S. Securities Exchange Act of 1934, as amended.

Material contracts

The following are material contracts, not entered into in the ordinary course of business, to which ArcelorMittal has been a party during the past two years.

ArcelorMittal Equity Incentive Plan, Performance Share Unit Plan and Special Grant

For a description of such plans, please refer to "Management and employees—Compensation."

Memorandum of Understanding

Mr. Lakshmi Mittal, Mrs. Usha Mittal, Lumen Investments S.à r.l., Nuavam Investments S.à r.l. (together, the "MoU Group") and the Company are parties to a Memorandum of Understanding ("MoU"), dated June 25, 2006, to combine Mittal Steel and Arcelor in order to create the world's leading steel company. (Lumen Investments S.à r.l. and Nuavam Investments S.à r.l. became parties following the assumption of the obligations of original parties to the MoU that have since ceased to hold Company shares). In April 2008, the Board of Directors approved resolutions amending certain provisions of the MoU in order to adapt it to the Company's needs in the post-merger and post-integration phase, as described under "Management and employees—Corporate governance— Operation—Lead Independent Director".

On the basis of the MoU, Arcelor's Board of Directors recommended Mittal Steel's offer for Arcelor, and the parties to the MoU agreed to certain corporate governance and other matters relating to the combined ArcelorMittal group. Certain provisions of the MoU relating to corporate governance were incorporated into the Articles of Association of ArcelorMittal at the extraordinary general meeting of the shareholders on November 5, 2007.

Certain additional provisions of the MoU expired effective August 1, 2009 and on August 1, 2011. ArcelorMittal's corporate governance rules will continue to reflect, subject to those provisions of the MoU that have been incorporated into the Articles of Association, the best standards of corporate governance for comparable companies and to conform with the corporate governance aspects of the NYSE listing standards applicable to non-U.S. companies and Ten Principles of Corporate Governance of the Luxembourg Stock Exchange.

The following summarizes the main provisions of the MoU that remain in effect or were in effect in 2024.

Standstill

The MoU Group agreed not to acquire, directly or indirectly, ownership or control of an amount of shares in the capital stock of the Company exceeding the percentage of shares in the Company that it will own or control following completion of the Offer (as defined in the MoU) for Arcelor and any subsequent offer or compulsory buy-out, except with the prior written consent of a majority of the independent directors on the Company's Board of Directors. Any shares acquired in violation of this restriction will be deprived of voting rights and shall be promptly sold by the MoU Group. Notwithstanding the above, if (and whenever) the MoU Group holds, directly and indirectly, less than 45% of the then-issued Company shares, the MoU Group may purchase (in the open market or otherwise) Company shares up to such 45% limit. In addition, the MoU Group is also permitted to own and vote shares in excess of the threshold mentioned in the immediately preceding paragraph or the 45% limit mentioned above, if such ownership results from (1) subscription for shares or rights in proportion to its existing shareholding in the Company where other shareholders have not exercised the entirety of their rights or (2) any passive crossing of this threshold resulting from a reduction of the number of Company shares (e.g., through self-tender offers or share buy-backs) if, in respect of (2) only, the decisions to implement such measures were taken at a shareholders' meeting in which the MoU Group did not vote or by the Company's Board of Directors with a majority of independent directors voting in favor.

Once the MoU Group exceeds the threshold mentioned in the first paragraph of this "Standstill" subsection or the 45% limit, as the case may be, as a consequence of any corporate event set forth in (1) or (2) above, it shall not be permitted to increase the percentage of shares it owns or controls in any way except as a result of subsequent occurrences of the

corporate events described in (1) or (2) above, or with the prior written consent of a majority of the independent directors on the Company's Board of Directors.

If subsequently the MoU Group sells down below the threshold mentioned in the first paragraph of this "Standstill" subsection or the 45% limit, as the case may be, it shall not be permitted to exceed the threshold mentioned in the first paragraph of this "Standstill" subsection or the 45% limit, as the case may be, other than as a result of any corporate event set out in (1) or (2) above or with the prior written consent of a majority of the independent directors.

Finally, the MoU Group is permitted to own and vote shares in excess of the threshold mentioned in the first paragraph of this "Standstill" subsection or the 45% limit mentioned above if it acquires the excess shares in the context of a takeover bid by a third party and (1) a majority of the independent directors of the Company's Board of Directors consents in writing to such acquisition by the MoU Group or (2) the MoU Group acquires such shares in an offer for all of the shares of the Company.

Non-compete

For so long as the MoU Group holds and controls at least 15% of the outstanding shares of the Company or has representatives on the Company's Board of Directors or Executive Office, the MoU Group and its affiliates will not be permitted to invest in, or carry on, any business competing with the Company, except for PT ISPAT Indo.

Exchange controls and other limitations affecting security holders

There are no legislative or other legal provisions currently in force in Luxembourg or arising under ArcelorMittal's Articles of Association that restrict the payment of dividends to holders of ArcelorMittal shares not resident in Luxembourg, except for regulations restricting the remittance of dividends and other payments in compliance with United Nations and EU sanctions. There are no limitations, either under the laws of Luxembourg or in the Articles of Association, on the right of non-Luxembourg nationals to hold or vote ArcelorMittal shares.

Luxembourg takeover law disclosure

The following disclosure is provided based on article 11 of the Luxembourg law of May 19, 2006 transposing Directive 2004/25/EC of the European Parliament and the Council of April 21, 2004 on takeover bids (the "Takeover Law"). The Articles of Association are available on www.arcelormittal.com, under Investors, Corporate Governance, Current Articles of Association.

With regard to articles 11(1)(a) and (c) of the Takeover Law, the Company has issued a single category of shares (ordinary shares), and the Company's shareholding structure showing each shareholder owning 5% or more of the Company's share capital is available elsewhere in this report and on www.arcelormittal.com under Investors, Corporate

Governance, Shareholding Structure, where the shareholding structure chart is updated monthly.

With regard to article 11(1)(b) of the Takeover Law, the ordinary shares issued by the Company are listed on various stock exchanges including NYSE and are freely transferable.

With regard to article 11(1)(d) of the Takeover Law, each ordinary share of the Company gives right to one vote, as set out in article 13.6 of the Articles of Association, and there are no special control rights attaching to the shares. Article 8 of the Articles of Association provides that the Mittal Shareholder (Mr Lakshmi N. Mittal, Mrs Usha Mittal or any of their heirs or successors acting directly or indirectly and/or the trust or trusts of which Mr. Lakshmi N. Mittal, Mrs. Usha Mittal and/or their heirs or successors are the beneficiaries, hold or control ArcelorMittal shares or any other entity controlled, directly or indirectly, by either of them) may, at its discretion, exercise the right of proportional representation and nominate candidates for appointment to the Board of Directors (defined as "Mittal Shareholder Nominees"). The Mittal Shareholder has not, to date, exercised that right.

Articles 11(1)(e) and (f) of the Takeover Law are not applicable to the Company. However, the sanction of suspension of voting rights automatically applies, subject to limited exceptions set out in the Transparency Law (as defined above), to any shareholder (or group of shareholders) who has (or have) crossed the thresholds set out in article 7 of the Articles of Association and articles 8 to 15 of the Transparency Law but have not notified the Company accordingly. The sanction of suspension of voting rights will apply until such time as the notification has been properly made by the relevant shareholder(s).

Article 11(1)(g) of the Takeover Law is not applicable to the Company.

With regard to article 11(1)(h) of the Takeover Law, the Articles of Association provide that the directors are elected at the annual general meeting of shareholders for a term that may not exceed three years, and may be re-elected. The rules governing amendments to the Articles of Association are described elsewhere in this report and are set out in article 19 of the Articles of Association.

With regard to article 11(1)(i) of the Takeover Law, the 2024 AGM granted the Board of Directors a new share buy-back authorization whereby the Board of Directors may authorize the acquisition or sale of Company shares including, but not limited to, entering into off-market and over-the-counter transactions and the acquisition of shares through derivative financial instruments, as well as to enter into cash-settled derivative financial instruments to mitigate the volatility in the share price paid to acquire shares in the Company. Any acquisitions, disposals, exchanges, contributions or transfers of shares by the Company or other companies in the ArcelorMittal group must be in accordance with the Luxembourg law of December 23, 2016 on market abuse,

Regulation (EU) No. 596/2014 of the European Parliament and of the Council of April 16, 2014 on market abuse and Commission Delegated Regulation (EU) No. 2016/1052 of March 8, 2016 with regard to regulatory technical standards for the conditions applicable to buy-back programs and stabilization measures and may be carried out by all means, on or off-market, including by a public offer to buy-back shares, or by the use of derivatives or option strategies. The fraction of the capital acquired or transferred in the form of a block of shares may amount to the entire program. Such transactions may be carried out at any time, including during a tender offer period, in accordance with applicable laws and regulations, including Section 10(b) and Section 9(a)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5 promulgated under the Exchange Act.

Articles 11(1)(j) and (k) of the Takeover Law are not applicable to the Company.

Taxation

United States taxation

The following discussion is a summary of the material U.S. federal income tax consequences that are likely to be relevant to U.S. Holders (as defined below) in respect of the ownership and disposition of ArcelorMittal common shares (hereinafter the "ArcelorMittal shares") that are held as capital assets (such as for investment purposes). This summary does not purport to address all material tax consequences that may be relevant to a particular U.S. Holder. This summary also does not take into account the specific circumstances of particular investors, some of which (such as tax-exempt entities, banks, insurance companies, broker-dealers, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, regulated investment companies, real estate investment trusts, partnerships and other pass-through entities, investors liable for any U.S. alternative minimum tax, investors that own or are treated as owning 10% or more of the total combined voting power or value of ArcelorMittal's shares, investors that hold ArcelorMittal shares as part of a straddle, hedge, conversion, constructive sale or other integrated transaction, and U.S. Holders whose functional currency is not the U.S. dollar) may be subject to special tax rules. This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), the Treasury regulations issued thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service ("IRS"), all as in effect on the date hereof, and the income tax treaty between the United States and Luxembourg dated April 3, 1996 (as amended by any subsequent protocols) (the "Treaty"). Those authorities

are subject to change (possibly with retroactive effect) or to differing interpretations.

This summary does not address any aspects of U.S. federal tax law other than income taxation, or any state, local, or non-U.S. tax considerations that may be applicable to investors, or the Medicare contribution tax applicable to net investment income of certain non-corporate U.S. Holders. Investors are urged to consult their tax advisors regarding the U.S. federal, state, local and other tax consequences of acquiring, owning and disposing of ArcelorMittal shares.

For purposes of this discussion, a "U.S. Holder" is a beneficial owner of ArcelorMittal shares that is, for U.S. federal income tax purposes:

• an individual citizen or resident of the United States;
• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States, any state thereof, or the District of Columbia; or
• any other person that is subject to U.S. federal income tax on a net income basis in respect of the ArcelorMittal shares.

The U.S. federal income tax consequences of a partner in a partnership holding ArcelorMittal shares generally will depend on the status of the partner and the activities of the partnership. The Company recommends that partners in such a partnership consult their own tax advisors.

Except where specifically described below, this discussion assumes that ArcelorMittal is not a passive foreign investment company ("PFIC") for U.S. federal income tax purposes. See "—Passive foreign investment company ("PFIC") status".

(a) Taxation of distributions

Cash distributions made by ArcelorMittal in respect of ArcelorMittal shares will constitute a taxable dividend when such distribution is actually or constructively received, to the extent such distribution is paid out of the current or accumulated earnings and profits of ArcelorMittal (as determined under U.S. federal income tax principles). The amount of any distribution will include the amount of any applicable Luxembourg withholding tax. To the extent the amount of any distribution received by a U.S. Holder in respect of ArcelorMittal shares exceeds the current or accumulated earnings and profits of ArcelorMittal, the distribution (1) will be treated as a non-taxable return of the U.S. Holder's adjusted tax basis in those ArcelorMittal shares and (2) thereafter will be treated as U.S.-source capital gain. Because ArcelorMittal does not maintain calculations of earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. Distributions of additional ArcelorMittal shares that are made to U.S. Holders with respect to their ArcelorMittal shares, and that are part of a pro rata distribution to all ArcelorMittal shareholders, generally will not be subject to U.S. federal income tax unless the U.S. Holder has the right to receive cash or property instead, in which case the U.S. Holder will be treated as if it received cash equal to the fair market value of the distribution.

The U.S. dollar amount of a taxable dividend generally will be included in the gross income of a U.S. Holder as ordinary income derived from sources outside the United States for U.S. foreign tax credit purposes and generally will be passive category income for purposes of the foreign tax credit limitation. Dividends paid in euro will be included in a U.S. Holder's income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date the dividend is received; a recipient of such dividends that converts such euro to dollars upon receipt generally should not be required to recognize foreign currency gain or loss in respect of the dividend income. Dividends paid by ArcelorMittal will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from U.S. corporations.

Taxable dividends received by certain non-corporate U.S. Holders (including individuals) with respect to the ArcelorMittal shares will be subject to U.S. federal income taxation at rates that are lower than the rates applicable to ordinary income if the dividends represent "qualified dividend income". Subject to certain exceptions for short-term or hedged positions, dividends paid on the ArcelorMittal shares will be treated as qualified dividend income if (i) the ArcelorMittal shares are readily tradable on an established securities market in the United States (such as the New York Stock Exchange) and (ii) ArcelorMittal is not a Passive foreign investment company ("PFIC") in the year in which the dividend was paid or in the year prior thereto. As discussed further below, ArcelorMittal believes that it was not a PFIC for U.S. federal income tax purposes with respect to its 2023 and 2024 taxable years, and ArcelorMittal does not expect to be a PFIC for its 2025 taxable year. See "—Passive foreign investment company ("PFIC") status".

U.S. Holders of ArcelorMittal shares should consult their own tax advisors regarding the availability of the reduced rate of U.S. federal income tax on dividends in light of their own particular circumstances.

Subject to generally applicable limitations and conditions, Luxembourg dividend withholding tax paid at the appropriate rate applicable to the U.S. Holder may be eligible for a credit against such U.S. Holder's U.S. federal income tax liability. These generally applicable limitations and conditions include requirements adopted by the IRS in regulations promulgated in December 2021, and any Luxembourg tax will need to satisfy these requirements in order to be eligible to be a creditable tax for a U.S. Holder. In the case of a U.S. Holder that either (i) is eligible for, and properly elects, the benefits of the Treaty, or (ii) consistently elects to apply a modified version of these rules under recently issued temporary

guidance and complies with specific requirements set forth in such guidance, the Luxembourg tax on dividends will be treated as meeting the new requirements and therefore as a creditable tax. In the case of all other U.S. Holders, the application of these requirements to the Luxembourg tax on dividends is uncertain, and we have not determined whether these requirements have been met. If the Luxembourg dividend tax is not a creditable tax for a U.S. Holder or the U.S. Holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year, the U.S. Holder may be able to deduct the Luxembourg tax in computing such U.S. Holder's taxable income for U.S. federal income tax purposes. The temporary guidance discussed above also indicates that the Treasury and the IRS are considering proposing amendments to the December 2021 regulations and that the temporary guidance can be relied upon until additional guidance is issued that withdraws or modifies the temporary guidance. The rules with respect to foreign tax credits are complex and involve the application of rules that depend on a U.S. Holder's particular circumstances. Accordingly, U.S. Holders are urged to consult their tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

(b) Taxation of sales, exchanges, or other dispositions of ArcelorMittal shares

Sales or other taxable dispositions by U.S. Holders of ArcelorMittal shares generally will give rise to gain or loss equal to the difference between the amount realized on the disposition and the U.S. Holder's tax basis in such ArcelorMittal shares, as determined in U.S. dollars. A U.S. Holder generally will have an initial tax basis in each ArcelorMittal share equal to its U.S. dollar cost to the U.S. Holder.

In general, gain or loss recognized on the sale or exchange of ArcelorMittal shares will be capital gain or loss and, if the U.S. Holder's holding period for such ArcelorMittal shares exceeds one year, will be long-term capital gain or loss. Certain U.S. Holders, including individuals, are eligible for preferential rates of U.S. federal income tax in respect of long-term capital gains. The deduction of capital losses against ordinary income is subject to limitations under the Code.

Passive foreign investment company ("PFIC") status Special U.S. federal income tax rules apply to investors owning stock of a PFIC. ArcelorMittal believes that it was not a PFIC for U.S. federal income tax purposes with respect to its 2023 and 2024 taxable years, and ArcelorMittal does not expect to be a PFIC for its 2025 taxable year. This conclusion is based upon an annual analysis of its financial position and an interpretation of the PFIC provisions that ArcelorMittal believes is correct. No assurances can be made, however, that the applicable tax law or relevant factual circumstances will not change in a manner that affects the determination of ArcelorMittal's PFIC status. If, contrary to the foregoing, ArcelorMittal were classified as a PFIC, a U.S. Holder would

be subject to a special tax at ordinary income tax rates on "excess distributions" (generally, any distributions that you receive in a taxable year that are greater than 125 percent of the average annual distributions that the U.S. Holder has received in the preceding three taxable years, or the U.S. Holder's holding period, if shorter), and gain that that the U.S. Holder recognizes on the sale of the holder's shares. Under these rules (a) the "excess distribution or gain will be allocated", ratably over the U.S. Holder's holding period, (b) the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income, and (c) the amount allocated to each of the other taxable years will be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit will be imposed with respect to the resulting tax attributable to each such other taxable year. If ArcelorMittal were a PFIC and its shares constitute "marketable stock", a U.S. Holder may elect to instead be taxed annually on a markto-market basis with respect to its ArcelorMittal shares and generally would not be subject to the PFIC rules described above. U.S. Holders should consult their tax advisors regarding the application of the PFIC rules to ArcelorMittal including the availability and consequences of a mark-tomarket election with respect to their shares of ArcelorMittal.

Foreign Financial Asset Reporting

Certain U.S. Holders that own "specified foreign financial assets" with an aggregate value in excess of U.S.\$50,000 on the last day of the taxable year or U.S.\$75,000 at any time during the taxable year are generally required to file an information statement along with their tax returns, currently on Form 8938, with respect to such assets. "Specified foreign financial assets" include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions. The understatement of income attributable to "specified foreign financial assets" in excess of U.S.\$5,000 extends the statute of limitations with respect to the tax return to six years after the return was filed. U.S. Holders who fail to report the required information could be subject to substantial penalties. U.S. Holders are encouraged to consult with their own tax advisers regarding the possible application of these rules, including the application of the rules to their particular circumstances.

Backup withholding and information reporting

The payment of proceeds received upon the sale, exchange or redemption of ArcelorMittal shares by U.S. Holders within the United States (or through certain U.S.-related financial intermediaries), and dividends on ArcelorMittal shares paid to U.S. Holders in the United States (or through certain U.S. related financial intermediaries), will be subject to information reporting and may be subject to backup withholding unless the U.S. Holder (1) is an exempt recipient, and establishes that exemption if required or (2) in the case of backup withholding, provides an IRS Form W-9 (or an acceptable substitute form)

that contains the U.S. Holder's taxpayer identification number and that certifies that no loss of exemption from backup withholding has occurred.

Backup withholding is not an additional tax. The amount of backup withholding imposed on a payment to a U.S. Holder will be allowed as a credit against the holder's U.S. federal income tax liability, if any, or as a refund, so long as the required information is properly furnished to the IRS. Holders that are not "U.S. persons" (as defined in the Code) may need to comply with certification procedures to establish their non-U.S. status in order to establish an exemption from information reporting and backup withholding.

THE SUMMARY OF U.S. FEDERAL INCOME TAX CONSEQUENCES SET OUT ABOVE IS INTENDED FOR GENERAL INFORMATION PURPOSES ONLY. EACH INVESTOR IN ARCELORMITTAL ORDINARY SHARES IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF ARCELORMITTAL SHARES BASED ON THE INVESTOR'S PARTICULAR CIRCUMSTANCES.

Luxembourg taxation

The following is a summary addressing certain material Luxembourg tax consequences that are likely to be relevant to holders of shares in respect of the ownership and disposition of shares in ArcelorMittal.

This summary does not purport to address all material tax considerations that may be relevant to a holder or prospective holder of ArcelorMittal shares. This summary also does not take into account the specific circumstances of particular investors some of which may be subject to special tax rules, including dealers in securities, financial institutions, insurance companies, investment funds.

This summary is based on the laws, regulations and applicable tax treaties as in effect on the date hereof in Luxembourg, all of which are subject to change, possibly with retroactive effect. Holders of ArcelorMittal shares should consult their own tax advisers as to the particular tax consequences, under the tax laws of the country of which they are residents for tax purposes of the ownership or disposition of ArcelorMittal shares.

This summary does not address the terms of employee stock options or other incentive plans implemented by ArcelorMittal and its subsidiaries and does not purport to provide the holders of stock subscription options or other comparable instruments (including shares acquired under employee share ownership programs) with a description of the possible tax and social security implications for them, nor to determine under which conditions these options or other instruments are or may become exercisable. These holders are therefore urged to consult their own tax advisers as to the potential tax and

social security implications of an exercise of their options or other instruments.

As used herein, a "Luxembourg individual" means an individual resident in Luxembourg who is subject to personal income tax (impôt sur le revenu) on his or her worldwide income from Luxembourg or foreign sources, and a "Luxembourg company" means a company or another entity resident in Luxembourg subject to corporate income tax (impôt sur le revenu des collectivités) on its worldwide income from Luxembourg or foreign sources. For the purposes of this summary, Luxembourg individuals and Luxembourg companies are collectively referred to as "Luxembourg Holders". A "non-Luxembourg Holder" means any investor in ArcelorMittal shares other than a Luxembourg Holder.

(a) Luxembourg withholding tax on dividends paid on ArcelorMittal shares

Dividends distributed by ArcelorMittal will in principle be subject to Luxembourg withholding tax at the rate of 15%.

Luxembourg resident corporate holders

Dividend withholding tax exemption applies on dividends paid by ArcelorMittal to a Luxembourg company (that is, a fully taxable entity within the meaning of Article 159 of the Luxembourg Income Tax Law) holding shares (or a Luxembourg permanent establishment/representative of a qualifying foreign entity to which the shares are attributable), which meets the qualifying participation test (that is, a shareholding in ArcelorMittal of at least 10% or having an acquisition cost of at least EUR 1.2 million held or committed to be held for a minimum one year holding period) under the conditions of Article 147 of the Luxembourg Income Tax Law). If such exemption from dividend withholding tax does not apply, a Luxembourg company may be entitled to a tax credit.

Luxembourg resident individual holders

Luxembourg withholding tax on dividends paid by ArcelorMittal to a Luxembourg resident individual holder may entitle such Luxembourg Holder to a tax credit for the tax withheld.

Non-Luxembourg Holders

Non-Luxembourg Holders of ArcelorMittal shares who have held a shareholding in ArcelorMittal representing at least 10% of ArcelorMittal's share capital (or shares with an acquisition cost of at least EUR 1.2 million) for an uninterrupted period of at least 12 months (or where held for a shorter period, where the holder takes the commitment to hold the qualifying shareholding for such period) may benefit from an exemption from the dividend withholding tax if they are: (i) entities which fall within the scope of Article 2 of the European Council Directive 2011/96/EU, as amended (the "EU Parent-Subsidiary Directive") and which are not excluded to benefit from the EU Parent-Subsidiary Directive under its mandatory general antiavoidance rule ("GAAR") in each case as implemented in Luxembourg, or (ii) corporates subject to a tax comparable to Luxembourg corporate income tax and which are resident of a country having concluded a double tax avoidance treaty with

Luxembourg, or (iii) corporates subject to a tax comparable to Luxembourg corporate income tax and which are resident in a State being part of the European Economic Area (EEA) other than a Member State of the European Union, or (iv) corporates resident in Switzerland subject to corporate income tax in Switzerland without benefiting from an exemption.

Non-Luxembourg Holders of ArcelorMittal shares who are tax resident in a country having a double tax avoidance treaty with Luxembourg may claim for a reduced withholding tax rate or a withholding tax relief under the conditions and subject to the limitations set forth in the relevant treaty.

(b) Luxembourg income tax on dividends paid on ArcelorMittal shares and capital gains

Luxembourg resident individual holders

For Luxembourg individuals, income in the form of dividends or capital gains derived from ArcelorMittal shares will normally be subject to individual income tax at the applicable progressive rate with a current top effective marginal rate of 45.78% including the unemployment fund contribution at the maximum rate of 9%. Such dividends may benefit from the 50% exemption set forth in Article 115(15a) of the Luxembourg Income Tax Law, subject to fulfillment of the conditions set out therein. Capital gains will only be taxable if they are realized on a sale of ArcelorMittal shares, which takes place within the first six months following their acquisition, or if the relevant holder (alone or together with his/her spouse or registered partner and his/her underage children), directly or indirectly, holds or has held more than 10% of the ArcelorMittal shares at any time during the past five years.

Luxembourg resident corporate holders

For Luxembourg companies, which do not benefit from a special tax regime, income in the form of dividends or capital gains derived from ArcelorMittal shares will be subject to corporate income tax and municipal business tax. The combined rate for these two taxes (including an unemployment fund contribution of 7%) for Luxembourg companies with registered office in Luxembourg City is 24.94% in 2024 (23.87% in 2025). Such dividends may benefit either from the 50% exemption set forth in Article 115(15a) of the Luxembourg Income Tax Law or from the full exemption set forth in Article 166 of the Luxembourg Income Tax Law, subject in each case to fulfillment of the respective conditions set out therein. Capital gains realized on the sale of ArcelorMittal shares may benefit from the full exemption provided for by the Grand Ducal Decree of December 21, 2001, as amended, subject to fulfillment of the conditions set out therein.

Non-Luxembourg Holders

An individual or corporate non-Luxembourg Holder of ArcelorMittal shares who/which realizes a gain on disposal thereof (and who/which does not have a permanent establishment in Luxembourg to which the ArcelorMittal shares would be attributable) will only be subject to Luxembourg taxation on capital gains arising upon disposal of such shares if such holder has (if an individual, alone or together with his or her spouse or registered partner and underage children) directly or indirectly held more than 10% of the capital of ArcelorMittal, at any time during the past five years, and either (1) such holder has been a resident of Luxembourg for tax purposes for at least 15 years and has become a non-resident within the last five years preceding the realization of the gain, subject to any applicable tax treaty, or (2) the disposal of ArcelorMittal shares occurs within six months from their acquisition, subject to any applicable tax treaty.

A corporate non-Luxembourg Holder, which has a permanent establishment or a permanent representative in Luxembourg to which ArcelorMittal shares would be attributable, will bear corporate income tax and municipal business tax on dividends received and/or a gain realized on a disposal of such shares under the same conditions as are applicable to a Luxembourg resident corporate holder, as described above.

(c) Other taxes

Net wealth tax

Luxembourg net wealth tax will not be levied on a Luxembourg Holder unless:

• the Luxembourg Holder is a legal entity subject to net wealth tax in Luxembourg; or
• ArcelorMittal shares are attributable to an enterprise or part thereof which is carried on through a permanent establishment or a permanent representative in Luxembourg of a non-resident entity.

Net wealth tax is levied annually at a digressive rate depending on the amount of the net wealth of the above holders, as determined for net wealth tax purposes (i.e. 0.5% on an amount up to EUR 500 million and 0.05% on the amount of taxable net wealth exceeding EUR 500 million).

ArcelorMittal shares may be exempt from net wealth tax subject to the conditions set forth by Article 60 of the Law of October 16, 1934 on the valuation of assets (Bewertungsgesetz), as amended.

Estate and gift tax

Luxembourg inheritance tax may be levied on the transfer of ArcelorMittal shares upon the death of a Luxembourg individual. No Luxembourg inheritance tax is, however, levied on the transfer of the ArcelorMittal shares upon the death of a holder in cases where the deceased was not a resident of Luxembourg for inheritance tax purposes.

Luxembourg gift tax will be levied in the event that a gift of ArcelorMittal shares is made pursuant to a notarial deed signed before a Luxembourg notary.

Other Luxembourg tax considerations

No registration tax will be payable by a holder of shares upon the issue, subscription or acquisition of shares in ArcelorMittal or upon the disposal of shares by sale or exchange.

Evaluation of disclosure controls and procedures

Disclosure controls and procedures

Management maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company's reports under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. ArcelorMittal's disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Management, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of December 31, 2024. Based upon that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2024, the Company's disclosure controls and procedures were effective.

Management's report on internal control over financial reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management assessed the effectiveness of internal control over financial reporting as of December 31, 2024 based upon the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").

Based on this assessment, management concluded that ArcelorMittal's internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of management's internal control over financial reporting as of December 31, 2024 has been audited by the Company's independent registered public accounting firm, Ernst & Young S.A., and their report as of March 10, 2025 below expresses an unqualified opinion on the Company's internal control over financial reporting.

Remediation of Previously Disclosed Material Weakness A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's financial statements will not be prevented or detected on a timely basis.

As described in ArcelorMittal's annual report for the year ended December 31, 2023, ArcelorMittal's management, with the oversight of the Audit & Risk Committee, concluded that its internal control over financial reporting was not effective as of December 31, 2023 due to a material weakness that was identified as a result of control deficiencies at one of the Company's Canadian subsidiaries, with respect to information technology general controls ("ITGCs") in the areas of user access and program change management over certain information technology ("IT") systems that support the recognition of sales and cost of sales, ineffective business process controls (automated and manual IT-dependent) due to the dependency on such ITGCs, and other ineffective business process controls supporting the recognition of sales and cost of sales. This material weakness did not result in any material misstatements in the consolidated financial statements.

During the year ended December 31, 2024, ArcelorMittal implemented a remediation plan to address this material weakness and to enhance the Company's control environment. The remediation plan included the following key actions to enhance ITGCs and other business process controls supporting the recognition of sales and cost of sales: (i) enhanced identification of IT applications relevant to internal control over financial reporting, (ii) appropriate implementation and operation of ITGCs with a focus on the areas of user access and program change management of certain IT systems that support the recognition of sales and cost of sales which had a cascading effect on business process controls (automated and manual IT-dependent), (iii) additional training of Company personnel and (iv) clear communication of control responsibilities through identification and education of the control owners as well as documentation of the procedure to be followed and the expected outcome.

As a result of these efforts and the control tests performed, ArcelorMittal's management concluded that the material weaknesses had been remediated as of December 31, 2024. Changes in Internal Control over Financial Reporting Except as noted in the preceding paragraphs, there have been no changes in the Company's internal control over financial reporting that occurred during the year ended December 31, 2024 that have materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

Mineral resource	is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.
Green steel	steel products subject to auditor verified certification of the CO2 savings achieved	Inferred mineral resource	is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve.
Mineral reserve	is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.

Note 1: General

ArcelorMittal Parent Company (the "Company") was incorporated as a "Société Anonyme" under Luxembourg law on June 8, 2001 for an unlimited period.

The Company has its registered office in 24-26 boulevard d'Avranches, Luxembourg City and is registered at the Register of Trade and Commerce of Luxembourg under the number B82.454.

The financial year of the Company starts on January 1 and ends on December 31 each year.

The Company's corporate goal is the manufacturing, processing and marketing of steel products, all other metallurgical products, mining products and any other activity directly or indirectly related thereto. The Company realizes its corporate goal either directly or through the creation of companies or the acquisition and holding of interests in companies, partnerships, associations, consortia and joint ventures.

These financial statements correspond to the separate financial statements of the ArcelorMittal Parent Company and were authorized for issuance on March 27, 2025 by the Company's Board of Directors. In conformity with the requirements of Luxembourg laws and regulations, the Company publishes consolidated financial statements in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and as adopted by the European Union.

Note 2: Basis of presentation

Statement of compliance

The financial statements have been prepared in accordance with IFRS as adopted by the European Union and in particular with IAS 27 Separate Financial Statements as well as in accordance with chapter IIbis and art 72bis of the Luxembourg amended law of December 19, 2002.

Adoption of new IFRS standards, amendments and interpretations applicable from January 1, 2024

On January 1, 2024, the Company adopted the narrow-scope amendments to IAS 1 which clarify how to classify debt and other liabilities as current or non-current. The amendments aim to promote consistency in applying the requirements by helping companies to determine whether, in the statement of financial position, debt and other liabilities with an uncertain settlement date should be classified as current (due or potentially due to be settled within one year) or non-current. The amendments include clarifications about the classification requirements for debt a company might settle by converting it into equity.

In addition, on January 1, 2024, the Company adopted the following amendments:

• 'Non-current Liabilities with Covenants (Amendments to IAS 1)' to clarify how conditions with which an entity must comply within twelve months after the reporting period affect the classification of a liability.
• Amendments to IFRS 16 'Leases' with respect to the lease liability in a sale and leaseback transaction. The amendments require a seller-lessee to subsequently measure lease liabilities arising from a leaseback in a way that it does not recognize any amount of the gain or loss that relates to the right of use it retains. The new requirements do not prevent a seller-lessee from recognizing in profit or loss any gain or loss relating to the partial or full termination of a lease.
• 'Supplier Finance Arrangements (Amendments to IAS 7 and IFRS 7)' to add disclosure requirements, and 'signposts' within existing disclosure requirements, which require entities to provide qualitative and quantitative information about supplier finance arrangements. In particular, entities will have to disclose in the notes information that enables users of financial statements to (i) assess how supplier finance arrangements affect an entity's liabilities and cash flows and to (ii) understand the effect of supplier finance arrangements on an entity's exposure to liquidity risk and how the entity might be affected if the arrangements were no longer available to it.

The adoption of these amendments did not have a material impact to the Company's financial statements.

The Company has adopted 'International Tax Reform – Pillar Two Model Rules (Amendments to IAS 12)' upon release on May 23, 2023. The amendments provided a temporary mandatory exception from deferred tax accounting for the top-up tax, which was effective immediately, and required new disclosures about the Pillar Two exposure as of December 31, 2023. The Company has applied a temporary mandatory relief from deferred tax accounting for the impacts of the top-up tax and accounts for it as a current tax when incurred.

New amendments applicable from 2025 onward

On August 15, 2023, the IASB published 'Lack of Exchangeability (Amendments to IAS 21)' that contains guidance to specify when a currency is exchangeable and how to determine the exchange rate when it is not and how an entity determines the exchange rate to apply when a currency is not exchangeable. The amendments also require the disclosure of additional information when a currency is not exchangeable. The amendments are effective for annual periods beginning on or after January 1, 2025 with early adoption permitted. The amendments do not apply retrospectively. An entity recognizes

any effect of initially applying the amendments as an adjustment to the opening balance of retained earnings when the entity reports foreign currency transactions. When an entity uses a presentation currency other than its functional currency, it recognizes the cumulative amount of translation differences in equity.

The Company does not expect that the adoption of this amendment will have a material impact to its financial statements. The Company does not plan to early adopt this amendment.

New IFRS standards and amendments not yet endorsed by the European Union

On April 9, 2024, the IASB published IFRS 18 'Presentation and Disclosure in Financial Statements' which includes requirements for all entities applying IFRS for the presentation and disclosure of information in financial statements. The objective of IFRS 18 is to set out requirements for the presentation and disclosure of information in general purpose financial statements (financial statements) to help ensure they provide relevant information that faithfully represents an entity's assets, liabilities, equity, income and expenses. Retrospective application of the standard is mandatory for annual reporting periods starting from January 1, 2027 onwards but earlier application is permitted.

On May 9, 2024, the IASB published IFRS 19 'Subsidiaries without Public Accountability: Disclosures' which specifies reduced disclosure requirements that an eligible entity is permitted to apply instead of the disclosure requirements in other IFRS Accounting Standards. IFRS 19 is effective for reporting periods beginning on or after January 1, 2027. Earlier application is permitted.

On May 30, 2024, the IASB issued 'Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7)' to address matters identified during the post-implementation review of the classification and measurement requirements of IFRS 9 'Financial Instruments'. The amendments relate to derecognition of a financial liability settled through electronic transfer, classification of financial assets and disclosures. The amendments are effective for reporting periods beginning on or after January 1, 2026. Earlier application of either all the amendments at the same time or only the amendments to the classification of financial assets is permitted.

On July 18, 2024, the IASB issued 'Annual Improvements— Volume 11' including minor amendments of IFRS 1 'First-time Adoption of International Financial Reporting Standards', IFRS 7 'Financial Instruments: Disclosures', IFRS 9 'Financial Instruments', IFRS 10 'Consolidated Financial Statements' and IAS 7 'Statement of Cash Flows'.

On December 18, 2024, the IASB issued 'Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7', which amend the own-use requirements in IFRS 9 to include the factors an entity is required to consider for contracts to buy and take delivery of renewable electricity for which the source of production of the electricity is nature-dependent. The hedge accounting requirements in IFRS 9 are also amended to permit an entity using a contract for nature-dependent renewable electricity with specified characteristics as a hedging instrument to designate a variable volume of forecast electricity transactions as the hedged item if specified criteria are met and to measure the hedged item using the same volume assumptions as those used for the hedging instrument. The amendments are effective for annual reporting periods beginning on or after January 1, 2026. Early application is permitted.

Except for the adoption of IFRS 18, for which the Company is still assessing the potential impact to its financial statements, ArcelorMittal does not expect that the adoption of the abovementioned standards and amendments will have a material impact to its financial statements. The Company does not plan to early adopt any standards or amendments.

Basis of measurement

The financial statements have been prepared on a historical cost basis, except for derivative financial instruments and financial assets measured at fair value through other comprehensive income ("FVOCI") which are measured at fair value less cost to sell.

Functional and presentation currency

These financial statements are presented in US dollars which is the Company's functional currency. Unless otherwise stated, all amounts are rounded to the nearest million, except share and earnings per share data.

Use of estimates and judgments

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

The following summary provides further information about the Company's critical accounting policies under which significant judgments, estimates and assumptions are made. It should be read in conjunction with the notes mentioned in the summary:

Deferred tax assets (note 16): The Company assesses the recoverability of deferred tax assets based on future taxable income projections, which are inherently uncertain and may be subject to changes over time. Judgment is required to assess the impact of such changes on the measurement of these assets and the time frame for their utilization. In addition, the Company applies judgment to recognize income tax liabilities when they are probable and can be reasonably estimated depending on the interpretation, which may be uncertain, of applicable tax laws and regulations. ArcelorMittal periodically reviews its estimates to reflect changes in facts and circumstances.

Impairment of investments in subsidiaries (note 7): In order to assess the recoverable amount of investments in subsidiaries, the Company mainly determines their value in use on the basis of the present value of cash flow projections. The estimates, judgments and assumptions applied for the value in use calculations relate primarily to growth rates, expected changes to average selling prices, shipments and direct costs of the underlying investments. Assumptions for average selling prices and shipments are based on historical experience and expectations of future changes in the market. When determining value in use, management also applies judgement when assessing whether cash flows expected to arise to achieve sustainability and decarbonization targets are deemed to maintain the same level of economic benefits or whether they improve or enhance the asset's performance. Discount rates are reviewed annually.

Note 3: Material accounting policies

The accounting policies set out below have been applied consistently by the Company to all periods presented in these financial statements.

(a) Foreign currency

Transactions in foreign currencies are translated to the functional currency of the Company at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are translated to the functional currency at the exchange rate at that date and the related foreign currency gain or loss are reported within financing costs-net in the statements of operations.

Non-monetary items in a foreign currency that are measured at historical cost are translated using the exchange rate at the date of the transaction. Foreign currency differences arising from translation of non-monetary assets and liabilities are recognized in the statements of operations.

(b) Fair value

The Company classifies the bases used to measure certain assets and liabilities at their fair value. Assets and liabilities

carried or measured at fair value have been classified into three levels based upon a fair value hierarchy that reflects the significance of the inputs used in making the measurements.

The levels are as follows:

Level 1: Quoted prices in active markets for identical assets or liabilities that the entity can access at the measurement date;

Level 2: Significant inputs other than within Level 1 that are observable for the asset or liability, either directly (i.e.: as prices) or indirectly (i.e.: derived from prices);

Level 3: Inputs for the assets or liabilities that are not based on observable market data and require management assumptions or inputs from unobservable markets.

(c) Financial instruments

(i) Non-derivative financial assets

The Company initially recognizes non-derivative financial assets on the date that they are originated, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the right to receive the contractual cash flows from the financial asset in a transaction in which substantially all the control of the financial asset are transferred. Any control in transferred financial assets that is created or retained by the Company is recognized as a separate asset or liability.

Financial assets and liabilities are offset and the net amount presented in the statements of financial position when, and only when, the Company has legal right to offset the amounts and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously.

The Company has the following non-derivative financial assets:

Loans and other financial assets

Loans and other financial assets are financial assets with fixed or determinable payments that are not quoted in an active market. Such assets are recognized initially at fair value plus any directly attributable transaction costs. Subsequent to initial recognition, loans and other financial assets are measured at amortized cost using the effective interest method, less any impairment losses when such loans and other financial assets are held within a business model whose objective is to hold financial assets in order to collect contractual cash flows that are solely payments of principal and interest on the principal amount outstanding. Impairment losses are recognized based on a change in expected credit losses. Loans and other financial

assets comprise receivables from other ArcelorMittal group entities, advances to suppliers and other receivables.

Cash and cash equivalents

Cash and cash equivalents consist of cash and short-term highly liquid investments that are readily convertible to cash with original maturities of three months or less at the time of purchase and are carried at cost plus accrued interest, which approximates fair value.

(ii) Non-derivative financial liabilities and equity instruments

Classification as debt or equity

Debt and equity instruments are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangement.

Equity instruments

Any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities is accounted for as an equity instrument. Equity instruments issued by the Company are recorded at the proceeds received, net of direct issuance costs. A contract that is settled by the Company receiving or delivering a fixed number of its own shares for no future consideration, or exchanging a fixed number of its own shares for a fixed amount of cash or another financial asset, is also recognized as an equity instrument.

Financial liabilities

Financial liabilities such as loans and borrowings and other payables are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual terms of the instrument.

Financial liabilities are recognized initially at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities are measured at amortized cost using the effective interest method.

The Company derecognizes a financial liability when its contractual obligations are settled or cancelled or expired.

Loans and borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least twelve months after the financial position date.

Financial guarantee contracts where the Company is required to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payment when due in accordance with the terms of a debt instrument are recognized at inception at fair value and subsequently measured at the higher of the expected credit loss allowance

and the amount initially recognized less any cumulative amount of income recognized.

(iii) Derivative financial instruments

The Company enters into derivative financial instruments principally to manage its exposure to fluctuations in exchange rates and the exposure of certain of its subsidiaries to price risk for raw materials and energy. Derivative financial instruments are classified as current or non-current assets or liabilities based on their maturity dates and are accounted for at trade date. Embedded derivatives are separated from the host contract and accounted for separately if they are not closely related to the host contract. The Company measures all derivative financial instruments based on fair values derived from market prices of the instruments or from option pricing models, as appropriate. Gains or losses arising from changes in fair value of derivatives are recognized in the statements of operations.

(d) Investments in subsidiaries, associates, joint ventures and other investments

Subsidiaries are those companies over which the Company exercises control. The Company controls an entity when it is exposed to or has rights to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Investments in subsidiaries are accounted for under the cost method.

Associated companies are those companies over which the Company has the ability to exercise significant influence on the financial and operating policy decisions and which are not subsidiaries. Generally, significant influence is presumed to exist when the Company holds more than 20% of the voting rights. Joint ventures are those companies over which the Company exercises joint control and has rights to the net assets of the arrangement. Investments in associates in which ArcelorMittal has the ability to exercise significant influence and joint ventures are accounted for at cost.

Investments in other entities, over which the Company does not have the ability to exercise significant influence and have a readily determinable fair value are accounted for at fair value with any resulting gain or loss recognized in the reserves in other comprehensive income. To the extent that these investments do not have a readily determinable fair value, they are accounted for under the cost method.

The Company reviews all its investments at each reporting date to determine whether there is an indicator that the investment may be impaired. If evidence indicates that the investment is impaired, ArcelorMittal calculates the amount of the impairment of the investment as being the difference between the higher of the fair value less costs to sell or its value in use and its carrying value.

(e) Impairment

Financial assets are assessed at each reporting date to determine whether there is any evidence that it is impaired or whenever changes in circumstances indicate that the carrying amount may not be recoverable. A financial asset is impaired if evidence indicates that a loss event has occurred after the initial recognition of the asset, and that the loss event had a negative effect on the estimated future cash flows of that asset that can be estimated reliably.

Evidence that financial assets are impaired can include default or delinquency by a debtor, restructuring of an amount due to the Company on terms that the Company would not consider otherwise, indications that a debtor or issuer will enter bankruptcy, adverse changes in the payment status of borrowers, economic conditions that correlate with defaults or the disappearance of an active market for a security.

The recoverable amount of investments is the greater of value in use and fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the investment.

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset's original effective interest rate. Losses are recognized in the statements of operations and reflected in an allowance account against receivables. Interest on the impaired asset continues to be recognized.

When a subsequent event causes the amount of impairment loss to decrease or if there has been a change in the estimates used to determine the recoverable amount, the decrease in impairment loss is reversed through the statements of operations.

(f) Leases

As a lessee, the Company assesses if a contract is or contains a lease at inception of the contract. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

The Company recognizes a right-of-use asset and a lease liability at the commencement date, except for short-term leases of twelve months or less and leases for which the underlying asset is of low value, which are expensed in the statement of operations on a straight-line basis over the lease term.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date,

discounted using the interest rate implicit in the lease, or, if not readily determinable, the incremental borrowing rate specific to the country, term and currency of the contract. Lease payments fixed payments, variable payments, as well as any extension. The lease liability is subsequently measured at amortized cost using the effective interest method and remeasured with a corresponding adjustment to the related right-of-use asset when there is a change in future lease payments in case of renegotiation, changes of an index or rate.

The right-of-use asset comprises, at inception, the initial lease liability, any initial direct costs and, when applicable, the obligations to refurbish the asset, less any incentives granted by the lessors. The right-of-use asset is subsequently depreciated, on a straight-line basis, over the lease term. Right-of-use assets are also subject to testing for impairment if there is an indicator for impairment.

In the statement of financial position, right-of-use assets and lease liabilities are classified, respectively, as part of property, plant and equipment and short-term/long-term debt, respectively.

(g) Provisions and accruals

The Company recognizes provisions for liabilities and probable losses that have been incurred when it has a present legal or constructive obligation as a result of past events and it is probable that the Company will be required to settle the obligation and a reliable estimate of the amount of the obligation can be made. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as a financing cost. Provisions for onerous contracts are recorded in the statements of operations when it becomes known that the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received.

(h) Income taxes

The Company is the head of a tax integration and is fully liable for the overall tax liability of the tax integration. Each of the entities included in the tax integration is charged with the amount of tax that relates to its individual taxable profit and this tax is paid to ArcelorMittal. Tax losses at entity level are transferred to the Company where they are offset with taxable profits for the determination of the net taxable income of the tax integration. Entities do not pay any tax expense to ArcelorMittal on their individual taxable profits prior to full utilization of their individual cumulative tax losses.

The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the statements of

operations because it excludes items of income or expense that are never taxable or deductible. The Company's current income tax expense (benefit) is calculated using tax rates that have been enacted or substantively enacted as of the statements of financial position date.

Deferred tax is recognized on differences between the carrying amounts of assets and liabilities, in the financial statements and the corresponding tax basis used in the computation of taxable profit, and is accounted for using the statements of financial position liability method. Deferred tax liabilities are generally recognized for all taxable temporary differences, and deferred tax assets are generally recognized for all deductible temporary differences. Deferred tax assets are recognized for net operating loss carry forwards of all entities within the tax integration to the extent that it is probable that taxable profits will be available against which those carry forwards can be utilized.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the statement of financial position date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

The carrying amount of deferred tax assets is reviewed at each statement of financial position date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to enable all or part of the asset to be recovered.

(i) Financing costs-net

Financing costs-net include mainly interest income and expense, gains (losses) on disposal of investments, fair value adjustments of the call option on mandatory convertible bonds, gains (losses) on other derivative instruments, premiums and fees on borrowings and foreign exchange gains and losses.

(j) Income from investments and from industrial franchise agreement

Dividend income is recognized when the shareholders' rights to receive payment have been established. Interest income is accrued as earned, by reference to the principal outstanding and at the prevailing effective interest rate. Income from contractually arranged corporate services is deducted from general and administrative expenses.

In connection with an industrial franchise agreement ("IFA") with group subsidiaries, the Company licenses its business model for manufacturing, processing and distributing steel to group subsidiaries. The business model includes the ArcelorMittal

business intelligence, which is a package of business solutions and implementation support combined with the development and maintenance of intangibles such as the ArcelorMittal brand, ArcelorMittal global information technology solutions, ArcelorMittal global research & development and ArcelorMittal global purchase agreements. The industrial franchise fee is calculated as a percentage of the steel sales of the franchisee entities after deduction of purchases of steel products from other franchisee entities.

(k) Earnings per common share

Basic earnings per common share is computed by dividing net income (loss) available to equity holders as per the consolidated financial statements by the weighted average number of common shares outstanding during the year. Diluted earnings per share is computed by dividing net income (loss) available to equity holders as per the consolidated financial statements by the weighted average number of common shares and potential common shares from share unit plans and outstanding stock options as well as potential common shares from the conversion of certain convertible bonds whenever the conversion results in a dilutive effect.

(l) Equity settled share-based payments

ArcelorMittal issues equity-settled share-based payments to certain employees, including restricted share units ("RSUs") and performance share units ("PSUs"). Equity-settled share-based payments are measured at fair value (excluding the effect of non market-based vesting conditions) at the grant date. The fair value determined at the grant date of the equity-settled sharebased payments is expensed on a graded vesting basis over the vesting period, based on the Company's estimate of the shares that will eventually vest and adjusted for the effect of non market-based vesting conditions. Where the fair value calculation requires modeling of the Company's performance against other market index, fair value is measured using the Monte Carlo pricing model to estimate the forecasted target performance goal for the Company and its peer companies. The expected life used in the model has been adjusted, based on management's best estimate, for the effects of nontransferability, exercise restrictions and behavioral considerations. In addition, the expected annualized volatility has been set by reference to the implied volatility of options available on ArcelorMittal shares in the open market, as well as, historical patterns of volatility. For the RSUs and PSUs, the fair value determined at the grant date of the equity-settled sharebased payments is expensed on a straight line method over the vesting period.

The main movements in 2024 are listed below:

1. ArcelorMittal Poland S.A.

On October 31, 2024 following a spin-off of ArcelorMittal Poland S.A., the Company recognized a 171 investment in ArcelorMittal Investment Management Poland Sp.z.o.o., which was subsequently contributed into AM Global Holding see below.

2. AM Global Holding

On November 18, 2024 the Company completed a capital increase in kind of 167 into AM Global Holding by transferring all shares held in ArcelorMittal Investment Management Poland Sp.z o.o.

Impairment

The Company assesses at the end of each reporting period whether there is any indication that its investments in subsidiaries may be impaired. As the Company's investments in subsidiaries correspond mainly to holding companies, in making this assessment, the Company considered indicators of impairment of steel and mining operations held directly and indirectly by such holding companies such as significant declines in operational results or changes in the outlook of future profitability, among other potential indicators. As of December 31, 2024, the Company determined that there was an indication that some of its investments in subsidiaries may be impaired or subject to an impairment reversal.

When an indication of impairment exists, the Company estimates the recoverable amount of the investments in subsidiaries measured based on the value in use of underlying steel and mining operations. The value in use was determined by estimating cash flows for a period of five years for subsidiaries holding businesses engaged in steel operations and over the life of the mines for those holding businesses engaged in mining operations. With respect to steel operations, the key assumptions for the value in use calculations are primarily the discount rates, growth rates, expected changes to average selling prices, shipments and direct costs during the period. Assumptions for average selling prices and shipments are based on historical experience and expectations of future changes in the market. Cash flow forecasts are derived from the most recent financial plans approved by management. Beyond the specifically forecasted period of five years, the Company extrapolates cash flows for the remaining years based on an estimated constant growth rate of 2%. This rate does not exceed the average long-term growth rate for the relevant markets. Regarding mining operations, the key assumptions for the value in use calculations are primarily the discount rates, capital expenditure, expected changes to average selling prices, shipments and direct costs during the period.

Management estimates discount rates using pre-tax rates that reflect current market rates for investments of similar risk. The rate for each investment was estimated from the weighted average cost of capital of producers, which operate a portfolio of assets similar to those of the Company's assets. The weighted average pre-tax discount rates used for the Company's steel business range from 10.6% to 18.7% and vary by geographic location.

The Company considered its exposure to certain climate-related risks which could affect its estimates of future cash flow projections applied for the determination of the recoverable amount of its investments. It considered the legal obligation of carbon neutrality by 2050 effective within the EU and in Canada following adoption of the Climate Law and the Net Zero Emission Accountability Act, respectively. Accordingly, with respect to its investments in flat steel operations in the EU and in Canada, ArcelorMittal included future decarbonization capital expenditures necessary to maintain the level of economic benefits expected to arise from the assets in their current condition in its assumptions for future cash flows of the recoverable amount of the respective investments. For other investment including steel operations applying the blast furnace basic oxygen furnace "BF-BOF" with decarbonization evolving at a different pace or not yet subject to a legal obligation of carbon neutrality, the Company increased risk premiums included in their discount rates until they are able to accelerate their decarbonization strategy to meet the Company's 2050 carbon neutrality objective and a legal obligation arises in the relevant jurisdiction. Due to economic developments,

uncertainties over the pace of transition to low-emission technologies, political and environmental actions that will be taken to meet the carbon reduction goals, regulatory changes and emissions activity arising from climate-related matters, the Company's assumptions used in the recoverable amount calculations are inherently uncertain and may ultimately differ from actual amounts.

In 2024, the Company recognized a total net impairment loss of 537. Impairment losses amounted to 2,286 (13,225 in 2023) and were mainly related to the Company's investments in AM Global Holding (1,544), ArcelorMittal Poland S.A. (361) and ArcelorMittal Investment S.à r.l. (322). Impairment reversals corresponding to impairment losses recognized in prior periods which no longer exists or have decreased amounted to 1,749 (310 in 2023) and were mainly related to the Company's investment in ArcelorMittal Spain Holding, S.L.U. for 1,681.

In 2023, the Company recognized a total net impairment loss of 12,915. Impairment losses were mainly related to the Company's investments in AM Global Holding (10,336), ArcelorMittal Spain Holding, S.L.U (1,513), ArcelorMittal Italy Holding S.r.l. (770), ArcelorMittal Poland S.A. (251) and ArcelorMittal France (224). Impairment reversal corresponding to an impairment loss recognized in prior periods which no longer exists or has decreased was related to the Company's investment in Ispat Inland S.à r.l. for 310.

This Facility replaced the 5.5 billion revolving credit facility dated December 19, 2018, which was amended and extended on April 27, 2021. The agreement incorporated a single tranche of 5.5 billion maturing on May 29, 2029, with two one-year extension options. The Facility contains restrictive covenants, which among other things, limit encumbrances on the assets of ArcelorMittal and its subsidiaries, the ability of ArcelorMittal's subsidiaries to incur debt and the ability of ArcelorMittal and its subsidiaries to dispose of assets in certain circumstances. The margin

On June 16, 2023, Standard & Poor's upgraded ArcelorMittal's outlook to positive and affirmed a long-term credit rating of 'BBB-'.

The Letter of Credit Facility is used by the Company and its subsidiaries for the issuance of letters of credit and other instruments. The terms of the letters of credit and other instruments contain certain restrictions as to duration. The Letter of Credit Facility, whose amount and maturity have been revised from time to time, amounted to 395 prior to refinancing through a 445 Letter of Credit Facility entered into on July 31, 2024, with maturity extended from July 31, 2024 to July 31, 2027 and with two extension options for one year each. The Letter of Credit Facility also includes an accordion clause which allows the Company to invite lenders to increase their commitments up to 595 in aggregate.

The following tables summarize the Company's bases used to measure its debt at fair value. Fair value measurement has been classified into three levels based upon a fair value hierarchy that reflects the significance of the inputs used in making the measurements.

					As of December 31, 2024
	Carrying amount				Fair Value
		Level 1	Level 2	Level 3	Total
Instruments payable bearing interest at fixed rates	7,914	8,008	133	—	8,141
Instruments payable bearing interest at variable rates	1,122	—	1,130	—	1,130

Commercial paper	745	—	758	—	758
					As of December 31, 2023
	Carrying amount				Fair Value
		Level 1	Level 2	Level 3	Total
Instruments payable bearing interest at fixed rates	7,014	6,969	278	—	7,247

Instruments payable bearing interest at variable rates	1,143	—	1,132	—	1,132
Total long-term debt, including current portion	8,157	6,969	1,410	—	8,379
Short term bank loans and other credit facilities including commercial paper	684	—	698	—	698

Instruments payable classified as Level 1 refer to the Company's listed bonds quoted in active markets. The total fair value is the official closing price as defined by the exchange on which the instrument is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

Instruments payable classified as Level 2 refer to all debt instruments not classified as Level 1. The fair value of the debt is based on estimated future cash flows converted into U.S. dollar at the forward rate and discounted using current U.S. dollar zero coupon rates and ArcelorMittal's credit spread quotations for the relevant maturities.

There were no instruments payable classified as Level 3.

Note 12: Financial instruments

Financial assets and liabilities mainly comprise:

• gross debt (see note 11)
• cash and cash equivalents (see note 4)
• derivative financial instruments (see below)
• other non-derivative financial assets and liabilities:

Other non-derivative financial assets and liabilities include loans from and to related parties (see note 10), certain prepaid expenses and other current and non-current assets (see notes 5 and 9), certain accrued expenses and other liabilities (see note 17) and certain long-term provisions and other obligations (see note 18).

The Company enters into derivative financial instruments to manage its exposure to fluctuations in exchange rates, the exposure of certain of its subsidiaries to price risk for raw materials and energy and its obligations out of mandatorily convertible bonds. The Company manages the counter-party risk associated with its instruments by centralizing its commitments and by applying procedures which specify, for each type of transaction and underlying position, risk limits and/ or the characteristics of the counter-party. The Company does not generally grant to or require guarantees from its counterparties for the risks incurred. Allowing for exceptions, the Company's counterparties are part of its financial partners and the related market transactions are governed by framework agreements (mainly International Swaps and Derivatives Association agreements which allow netting only in case of counterparty default). Accordingly, derivative assets and derivative liabilities are not offset.

Fair values versus carrying amounts

The estimated fair values of certain financial instruments have been determined using available market information or other valuation methodologies that require judgment in interpreting market data and developing estimates.

The following table summarize assets and liabilities based on their categories at December 31, 2024:

The Company classifies the bases used to measure certain assets and liabilities at their fair value. Assets and liabilities carried or measured at fair value have been classified into three levels based upon a fair value hierarchy that reflects the significance of the inputs used in making the measurements.

The levels are as follows:

Level 1: Quoted prices in active markets for identical assets or liabilities that the entity can access at the measurement date;

Level 2: Significant inputs other than within Level 1 that are observable for the asset or liability, either directly (i.e.: as prices) or indirectly (i.e.: derived from prices);

Level 3: Inputs for the assets or liabilities that are not based on observable market data and require management assumptions or inputs from unobservable markets.

The following tables summarize the bases used to measure certain assets and liabilities at their fair value on recurring basis:

	As of December 31, 2024
	Level 1	Level 2	Level 3	Total
Assets at fair value:
Investments in equity instruments at FVOCI	26	—	—	26
Derivative current assets	—	16	—	16
Derivative non-current assets	—	50	—	50
Total assets at fair value	26	66	—	92
Liabilities at fair value:
Derivative current liabilities	—	156	—	156
Derivative non-current liabilities	—	287	—	287
Total liabilities at fair value	—	443	—	443

			As of December 31, 2023
	Level 1	Level 2	Level 3	Total
Assets at fair value:
Investments in equity instruments at FVOCI	26	—	—	26
Derivative current assets	—	74	—	74
Derivative non-current assets	—	59	—	59
Total assets at fair value	26	133	—	159
Liabilities at fair value:
Derivative current liabilities	—	72	—	72
Derivative non-current liabilities	—	6	—	6
Total liabilities at fair value	—	78	—	78

Investments in equity instruments at FVOCI classified as Level 1 refer to listed securities quoted in active markets. A quoted market price in an active market provides the most reliable evidence of fair value and is used without adjustment to measure fair value whenever available, with limited exceptions. The total fair value is either the price of the most recent trade at the time of the market close or the official close price as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

Derivative financial assets and liabilities classified as Level 2 refer to instruments to hedge fluctuations in foreign exchange rates and energy. The total fair value is based on the price a dealer would pay or receive for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and the fair value is calculated using standard industry models based on significant observable market inputs such as foreign exchange rates, energy prices, swap rates and interest rates.

Risk management policy

The Company's operations expose it to a variety of financial risks including interest rate risk, foreign exchange risk, liquidity risk and risks in fluctuations in prices of energy on behalf of certain of its subsidiaries. The Company actively monitors and seeks to reduce volatility of these exposures through a diversity of financial instruments, where considered appropriate. The Company has formalized how it manages these risks within the Treasury and Financial Risk Management Policy, which has been approved by Management.

Capital management

The Company's objective when managing capital is to safeguard continuity, maintain a strong credit rating and healthy capital ratios to support its business and provide adequate return to shareholders through continuing growth.

The Company sets the amount of capital required on the basis of annual business and long-term operating plans which include capital and other strategic investments. The funding requirement is met through a combination of equity, bonds and other longterm and short-term borrowings.

The Company monitors capital using a gearing ratio, being the ratio of net debt as a percentage of total equity.

	December 31,
	2024	2023
Total equity	56,147	57,140
Net debt	6,093	3,287
Gearing	10.85%	5.75%

Interest rate risk

The Company is exposed to interest rate risk on short-term and long-term floating rate instruments and on refinancing of fixed rate debt. The Company's policy is to maintain a balance of fixed and floating interest rate borrowings, which is adjusted depending on the prevailing market interest rates and outlook. As at December 31, 2024, the long-term debt was comprised of 88% fixed rate debt and 12% variable rate debt (see note 11). The Company may utilize certain instruments to manage interest rate risks. Interest rate instruments allow the Company to borrow long-term at fixed or variable rates, and to swap the rate of this debt either at inception or during the lifetime of the borrowing. The Company and its counterparties exchange, at predefined intervals, the difference between the agreed fixed rate and the variable rate, calculated on the basis of the notional amount of the swap. Similarly, swaps may be used for the exchange of variable rates against other variable rates.

Foreign exchange rate risk

The Company is exposed to changes in values arising from foreign exchange rate fluctuations generated by its operating activities. Because a substantial portion of ArcelorMittal's assets, liabilities, income and expenses are denominated in

currencies other than the U.S. dollar (its reporting currency), ArcelorMittal has an exposure to fluctuations in the values of these currencies relative to the U.S. dollar. These currency fluctuations, especially the fluctuation of the value of the U.S. dollar relative to the euro, Brazilian real, Mexican peso, Canadian dollar, Polish Zloty and South African rand could have a material impact on its financial position and results of operations.

ArcelorMittal also faces foreign currency translation risk, which arises when ArcelorMittal translates its net debt (see note 11) and other items denominated in currencies other than the U.S. dollar. Following its Treasury and Financial Risk Management Policy, the Company hedges a portion of its net exposure to foreign exchange rates through forwards, options and swaps.

The Company may also use derivative instruments at the corporate level to hedge debt recorded in foreign currency other than the functional currency or the balance sheet risk associated with certain monetary assets denominated in a foreign currency other than the functional currency.

Liquidity Risk

Liquidity risk is the risk that the Company may encounter difficulties in meeting its obligations associated with financial liabilities that are settled by delivering cash. ArcelorMittal Treasury S.N.C is responsible for the Company's funding and liquidity management. ArcelorMittal's principal sources of liquidity are cash generated from its operations and its credit lines. The Company actively manages its liquidity. Following the Company's Treasury and Financial Risk Management Policy, the levels of cash, credit lines and debt are closely monitored and appropriate actions are taken in order to comply with the covenant ratios, leverage, fixed/floating ratios, maturity profile and currency mix.

The contractual maturities of the below financial liabilities include estimated loan repayments, interest payments and settlement of derivatives, excluding any impact of netting agreements. The cash flows are calculated based on market data as of December

31, 2024, and as such are sensitive to movements in mainly foreign exchange rates and interest rates. The cash flows are non-discounted, except for derivative financial liabilities where the cash flows equal their fair values.

Energy and raw materials price risks

The Company hedges the exposure to fluctuations in natural gas and raw materials prices in certain of its subsidiaries and uses financial instruments such as forward purchases or sales, options and swaps in order to manage such volatility. The fair value of such instruments categorized as Level 2 was (31) and 17 at December 31, 2024 and 2023, respectively.

Sensitivity analysis

Foreign currency sensitivity

The following tables detail the Company's derivative financial instruments' sensitivity as it relates to derivative financial instruments to a 10% strengthening and a 10% weakening in the U.S. dollar against the euro. A positive number indicates an increase in profit or loss and other equity, where a negative number indicates a decrease in profit or loss and other equity.

The sensitivity analysis includes the Company's complete portfolio of foreign currency derivatives outstanding. The impact on the non €/\$ derivatives reflects the estimated move of such currency pairs, when the U.S. dollar appreciates or depreciates 10% against the euro, based on computations of correlations in the foreign exchange markets in 2024.

Share capital

On April 28, 2023, ArcelorMittal cancelled 25 million treasury shares to keep the number of treasury shares within appropriate levels. This cancellation took into account the shares already purchased under the 60,431,380 share buyback program (see below). Following this cancellation, the aggregate number of shares issued and fully paid up and share capital decreased from 877,809,772 and 312 as of December 31, 2022 to 852,809,772 and 303 as of December 31, 2023, respectively. Share capital remained unchanged at December 31, 2024.

Authorized shares

Following the cancellation of treasury shares on April 28, 2023, authorized share capital decreased from 404 represented by 1,136,418,599 ordinary shares without nominal value as of December 31, 2022 to 395 represented by 1,111,418,599 ordinary shares without nominal value as of December 31, 2023 and remained unchanged at December 31, 2024.

Share buyback

On April 25, 2022, ArcelorMittal completed its 1,000 share buyback program announced on February 11, 2022 under the authorization given by the annual general meeting of shareholders of June 8, 2021 and repurchased 31.8 million shares for a total value of €911 million (equivalent to 1,000) at an approximate average price per share of €28.68 (\$31.49).

On June 8, 2022, ArcelorMittal completed a second share buyback program in the amount of 1,000 under the authorization given by the annual general meeting of shareholders of May 4, 2022, bringing the total 2022 buybacks announced so far to 2,000. ArcelorMittal repurchased 33.3 million shares for a total value of €943 million (equivalent to 1,000) at an approximate average price per share of €28.26 (\$29.99).

On July 29, 2022, the Company announced a third share buyback program of 60.4 million shares (approximately 1.4 billion based on share price as of July 26, 2022) to be completed by the end of May 2023 (subject to market conditions) under the authorization given by the annual general meeting of shareholders of May 4, 2022. The Significant Shareholder has decided not to participate in the program consistent with the position announced on February 25, 2022. On March 31, 2023, ArcelorMittal completed the share buyback program. The total repurchase value was €1,456 million (1,492) at an approximate average price per share of €24.10 (\$24.68).

On May 5, 2023, ArcelorMittal announced the commencement of a new buyback program of up to 85 million shares under the authorization given by the annual general meeting of shareholders of May 2, 2023, to be completed by May 2025. The actual amount of shares that will be repurchased pursuant to this new program will depend on the level of post-dividend free cash flow ("FCF") (calculated as net cash provided by operating activities less purchases of property, plant and equipment and intangibles less dividends paid to non-controlling shareholders) generated over the period (the Company's defined policy is to return a minimum of 50% of post-dividend annual FCF), the continued authorization by shareholders, and market conditions. At market closure on December 31, 2024, ArcelorMittal had repurchased 78.2 million shares for a total value of €1,802 million (1,952) at an average price per share of €23.03 (\$24.96).

The shares acquired under the different programs are intended to reduce ArcelorMittal's share capital, and/or to meet ArcelorMittal's obligations arising from employee share programs.

Mandatorily convertible subordinated notes

On May 18, 2020, the Company completed an offering of mandatorily convertible subordinated notes ("MCNs") due May 18, 2023 for 1,250. The MCNs had a three-year maturity, were issued at 100% of the principal amount and were mandatorily

converted into common shares of the Company upon maturity unless converted earlier at the option of the holders or ArcelorMittal during the conversion period or upon occurrence of certain defined events. The Company determined that the MCNs were a hybrid instrument including an equity component and a debt component.

On May 19, 2023, upon mandatory conversion of the 24,290,025 outstanding MCNs due May 18, 2023, ArcelorMittal delivered a total of 57,057,991 treasury shares (of which 9,396,120 to the Significant Shareholder) with a carrying amount of 1,534. Following the mandatory conversion, the Company derecognized the 509 equity component presented separately in the statements of changes in equity and recognized a 1,025 (794 net of tax) decrease in additional paid-in capital.

Treasury shares

As of December 31, 2024 and 2023, the Company held 84.3 million and 33.5 million treasury shares, respectively.

Legal reserve

In accordance with Luxembourg Company Law, the Company is required to transfer a minimum of 5% of its net profit for each financial year to a legal reserve. This requirement ceases to be necessary once the balance of the legal reserve reaches 10% of the subscribed capital.

Earnings per common share

Basic earnings per common share is computed by dividing net income attributable to equity holders of the parent in accordance with the Company's consolidated financial statements by the weighted average number of common shares outstanding during the year. Diluted earnings per share is computed by dividing net income attributable to equity holders of the parent in accordance with the Company's consolidated financial statements by the weighted average number of common shares plus potential common shares from share unit plans whenever the conversion results in a dilutive effect.

The following table provides the numerators and a reconciliation of the denominators used in calculating basic and diluted earnings per common share for the years ended December 31, 2024 and 2023:

	Year ended December 31,
	2024	2023
Consolidated net income attributable to equity holders of the parent	1,339	919
Weighted average common shares outstanding (in millions) for the purpose of basic earnings per share	788	842
Incremental shares from assumed conversion of restricted share units and performance share units (in millions)	3	3
Weighted average common shares outstanding (in millions) for the purpose of diluted earnings per share	791	845

Dividends

Note 16: Income tax

The Company has adopted International Tax Reform – Pillar Two Model Rules (Amendments to IAS 12 upon their release on May 23, 2023). The Amendments provide a temporary mandatory exception from deferred tax accounting for the top-up tax, which is effective immediately, and require new disclosures about the Pillar Two exposure from December 31, 2023. The Company has applied a temporary mandatory relief from deferred tax accounting for the impacts of the top-up tax and accounts for it as a current tax when incurred.

Pillar Two legislation has been enacted or substantively enacted in the jurisdiction of ArcelorMittal S.A. and in certain other jurisdictions where the Company operates. The legislation is effective for the Company's financial year beginning January 1, 2024. Based on the applicable criteria, the Company is subject to Pillar Two minimum tax.

Non-deductible impairments	76	449
Exempted dividend income	(858)	(744)
Other permanent items	1	11
Total permanent items	(781)	(284)

Non-deductible impairments: Impairments of investments in subsidiaries are generally tax deductible under the Luxembourg tax legislation. However impairments are not tax-deductible if they (i) are neutralized with exempt dividend income, exempt capital gains and mark to market valuation, or (ii) arise within the tax consolidation (up to the tax loss incurred by the subsidiary). These non-deductible (taxable) impairment (reversals) amounted to 305 and 1,800 in 2024 and 2023, respectively.

Exempted dividend income: Under Article 166 of the Luxembourg tax law, dividend income, liquidation proceeds, and capital gains may be treated as tax-exempt to the extent certain requirements are met relating to the parent's participation in the subsidiary. The participation exemption applies if the Luxembourg parent maintains (or commits to hold) a minimum

Deferred tax assets and liabilities

The origin of deferred tax assets and liabilities is as follows:

holding in a qualified subsidiary company (generally a shareholding of at least 10% or having an acquisition cost of at least €1.2 million) for an uninterrupted period of at least 12 months.

Rate changes: The 374 tax expense resulting from rate changes in 2024 is due to the decrease from 24.94% to 23.87% of the statutory tax rate as enacted in Luxembourg and applied to deferred taxes.

Net change in measurement of deferred tax assets

The 2024 net change in measurement of deferred tax assets of 158 mainly consists of unrecognized deferred tax asset related to net tax deductible loss for the period .

The 2023 net change in measurement of deferred tax assets of 2,005 mainly consists of 2,378 unrecognized deferred tax assets due to impairments of investments not considered deductible for tax, and (373) recognition of tax losses for carried forward based on revised taxable income forecast of ArcelorMittal and its subsidiaries included in the tax integration.

Uncertain tax positions

ArcelorMittal takes income tax positions that management believes are supportable and are intended to withstand challenge by tax authorities. Some of these positions are inherently uncertain and include those relating to transfer pricing matters and the interpretation of income tax laws applied to complex transactions. The Company periodically reassesses its tax positions. Changes to the financial statement recognition, measurement, and disclosure of tax positions is based on management's best judgment given any changes in the facts, circumstances, information available and applicable tax

laws. Considering all available information and the history of resolving income tax uncertainties, the Company believes that the ultimate resolution of such matters will not have a material effect on the Company's financial position, statements of operations or cash flows.

Tax credits	8	8	—	8
Other temporary differences	9.535	2,378	—	2,378
Total		32,559	8,720	23,839

As of December 31, 2024, deferred tax assets not recognized relate to (i) tax losses carried forward, and (ii) other temporary differences representing the impairments of investments not considered deductible for tax. The utilization of tax losses carried forward is restricted to the taxable income of the Luxembourg tax consolidated group. The utilization of tax losses carried forward may be also restricted by the character of the income.

The total amount of accumulated tax losses amounted to 130,581 as of December 31, 2024. Of this amount 35,149 was considered realizable, resulting in the recognition of 8,390 of deferred tax assets at the applicable income tax rate in Luxembourg. The total amount of accumulated tax losses amounted to 120,982 as of December 31, 2023. Of this amount 34,964 was considered realizable, resulting in the recognition of 8,720 of deferred tax assets at the applicable income tax rate in Luxembourg. Under the Luxembourg tax legislation the tax losses generated until the end of 2016 can be carried forward indefinitely and are not subject to any specific yearly loss utilization limitations. Of the total of 130,581 accumulated tax losses, tax losses of 21,677 will expire within the next 12 to 17 years. The remaining amount can be carried forward indefinitely. The tax losses carried forward related primarily to tax deductible impairments of investments in consolidated subsidiaries recorded by certain of the ArcelorMittal group's holding companies in Luxembourg. Out of the total tax losses carried

forward, 69.9 billion may be subject to recapture in the future if the write-downs that caused them are reversed creating taxable income unless the Company converts them to permanent through sales or other organizational restructuring activities.

The Company believes that it is probable that sufficient future taxable profits will be generated to support the recognized deferred tax asset for tax losses carried forward in Luxembourg. As part of its recoverability assessment the Company has taken into account: (i) its most recent forecast approved by management and the Board of Directors, (ii) the likelihood that the factors that have contributed to past losses in Luxembourg will not recur, (iii) the fact that ArcelorMittal in Luxembourg is the main provider of funding to the Company's consolidated subsidiaries, leading to significant amounts of taxable interest income on outstanding and future loans as updated based on most recent funding strategy, (iv) the expected level of interest expenses in Luxembourg driven by the Group net debt level, (v) the industrial franchise agreement whereby ArcelorMittal S.A. licenses its business model for manufacturing, processing and distributing steel to group subsidiaries, and (vi) other significant and reliable sources of operational income earned from ArcelorMittal's European and worldwide operating subsidiaries for centralized distribution and procurement activities performed in Luxembourg.

The Company has also considered the implications of the netzero path and its carbon emissions intensity reduction targets on its future taxable profits expectations in relation to the existing business models and the potential future financing of such projects, resulting in no major impact on the estimated level of future taxable profit. In performing the assessment, the Company estimates at which point in time its earnings projections are no longer reliable, and thus taxable profits are no longer probable. Accordingly, the Company has established consistent forecast periods for its different income streams for estimating probable future taxable profits, against which the unused tax losses can be utilized in Luxembourg.

At December 31, 2024, based upon the level of historical taxable income and projections for future taxable income over the periods in which the deductible temporary differences are anticipated to reverse, management believes it is probable that ArcelorMittal will realize the benefits of the deferred tax assets of 8,390 recognized. The amount of future taxable income required to be generated by ArcelorMittal's subsidiaries to utilize the deferred tax assets of 8,390 is at least 35,149. Historically, the Company has been able to generate taxable income in sufficient amounts and believes that it will generate sufficient levels of taxable income upcoming years to permit the Company to utilize tax benefits associated with tax losses carried forward and other deferred tax assets that have been recognized in its financial statements. In the event that a history of recent losses is present, the Company relied on convincing other positive evidence such as the character of (historical) losses and tax planning to support the deferred tax assets recognized.

At December 31, 2023, based upon the level of historical taxable income and projections for future taxable income over the periods in which the deductible temporary differences are anticipated to reverse, management believes it is probable that ArcelorMittal will realize the benefits of the deferred tax assets of 8,720 recognized. The amount of future taxable income required to be generated by ArcelorMittal's subsidiaries to utilize the deferred tax assets of 8,720 is at least 34,964. Historically, the Company has been able to generate taxable income in sufficient amounts and believes that it will generate sufficient levels of taxable income upcoming years to permit the Company to utilize tax benefits associated with tax losses carried forward and other deferred tax assets that have been recognized in its financial statements. In the event that a history of recent losses is present, the Company relied on convincing other positive evidence such as the character of (historical) losses and tax planning to support the deferred tax assets recognized.

Note 20: Contingencies

The Company is currently and may in the future be involved in litigation, arbitration or other legal proceedings. Provisions related to legal and arbitration proceedings are recorded in accordance with the principles described in note 3.

On May 15, 2012, ArcelorMittal received a writ of summons on behalf of Association des Actionnaires d'Arcelor ("AAA"), a French association of former minority shareholders of Arcelor to appear before the civil court of Paris. The AAA alleged in particular that, based on Mittal Steel's and Arcelor's disclosure and public statements, investors had a legitimate expectation that the exchange ratio in the second-step merger would be the same as that of the secondary exchange offer component of Mittal Steel's June 2006 tender offer for Arcelor (i.e., 11 Mittal Steel shares for 7 Arcelor shares), and that the second-step merger did not comply with certain provisions of company law. AAA claimed, inter alia, damages in a nominal amount and reserved the right to seek additional remedies including the cancellation of the merger. The proceedings before the civil court of Paris were stayed, pursuant to a ruling of such court on July 4, 2013, pending a preparatory investigation (instruction préparatoire) by a criminal judge magistrate (juge d'instruction) triggered by the complaints of AAA and several hedge funds (who quantified their total alleged damages at 282). The dismissal of charges (non-lieu) ending the preparatory investigation became final in March 2018. On March 6, 2020 AAA revived its claim before the civil court of Paris on its behalf and on behalf of the hedge funds who had also filed a criminal complaint, as well as two new plaintiffs. In October 2024, the court ruled in ArcelorMittal's favor, dismissing all of AAA's

claims. Following AAA's appeal in December 2024, AAA filed their first brief in March 2025, which quantified its damages claim at 420 (€404 million) plus interest.

Note 21: Personnel and deferred employee benefits

Employees and key management personnel

As of December 31, 2024 and 2023, the Company had a workforce comprising 184 and 173 people, respectively, and the total annual compensation of the Company's employees paid in 2024 and 2023 was as follows:

	Year ended December 31,
	2024	2023
Employee Information
Wages and salaries	33	36
Social security costs	2	3
Other staff expenses	9	8
Total	44	47

The total annual compensation of ArcelorMittal's key management personnel, including its Board of Directors, paid in 2024 and 2023 was as follows:

	Year ended December 31,
	2024	2023
Base salary and/or directors fees	2	2
Short-term performance-related bonus	3	3

The fair value of the shares attributed in the framework of RSU and PSU plans to the ArcelorMittal's key management personnel is recorded as an expense in the statements of operations over the relevant vesting periods.

As of December 31, 2024 and 2023, ArcelorMittal did not have outstanding any loans or advances to members of its Board of Directors or key management personnel, and had not given any guarantees for the benefit of any member of its Board of Directors or key management personnel.

Deferred employee benefits

Certain employees of ArcelorMittal are included in the unfunded defined benefit pension plan managed by the Company's affiliate ArcelorMittal Luxembourg. The Company has a defined benefit obligation with respect to this plan by virtue of a contractual arrangement with ArcelorMittal Luxembourg. Benefits are based on such employees' length of service and applicable pension table under the terms of the agreement. This defined benefit pension plan was closed to new entrants on December 31, 2007 and replaced by a defined contribution

pension plan for active members financed by employer and employee contributions.

The following table details the reconciliation of the defined benefit pension obligation:

	December 31,
	2024	2023

Service cost is included in general administrative expense. Interest cost is included in financing costs – net.

Assumptions used to determine benefit obligations

	December 31,
	2024	2023
Discount rate	3.40 %	3.30 %
Rate of compensation increase	3.10 %	3.20 %

Cash contributions and maturity profile of the plans

In 2024, the Company expects its cash contributions to amount to 3 for pension plans.

At December 31, 2024, the duration of the liabilities related to the pension plan was 10 years (2023:10 years).

Risks associated with defined benefit plans

Through its defined benefit pension plans, ArcelorMittal is exposed to a number of risks, the most significant of which is the change in bond yields. A decrease in corporate bond yields will increase plan liabilities.

Sensitivity analysis

The following information illustrates the sensitivity to a change in certain assumptions related to ArcelorMittal's pension plan (as of December 31, 2024, the defined benefit obligation ("DBO") for pension was 18):

	Effect on 2025 pre-tax pension expense (sum of service cost and interest cost) 1	Effect on December 31, 2024 DBO
Change in assumption
100 basis point decrease in discount rate	—	2
100 basis point increase in discount rate	—	(2)
100 basis point decrease in rate of compensation	—	(1)
100 basis point increase in rate of compensation	—	1

1. Amounts are not disclosed as they are below 1 and rounded to nearest million.

The above sensitivities reflect the effect of changing one assumption at a time. Actual economic factors and conditions often affect multiple assumptions simultaneously, and the effects of changes in key assumptions are not necessarily linear.

Share-based payments

ArcelorMittal Equity Incentive Plan

ArcelorMittal operates a long-term incentive plan ("the ArcelorMittal Equity Incentive Plan") to incentivize shareholder wealth creation in excess of performance of a peer group and incentivize executives to achieve strategy. The ArcelorMittal Equity Incentive Plan is intended to align the interests of the Company's shareholders and eligible employees by allowing them to participate in the success of the Company. The ArcelorMittal Equity Incentive Plan provides for the grant of RSUs and PSUs to eligible Company employees (including Executive Officers) and is designed to incentivize employees, improve the Company's long-term performance and retain key employees.

The grant of PSUs under the ArcelorMittal Equity Incentive Plan aims to serve as an effective performance-enhancing scheme

based on the employee's contribution to the eligible achievement of the Company's strategy. Awards in connection with PSUs are subject to the fulfillment of cumulative performance criteria over a three-year period from the date of the PSU grant such as return on capital employed ("ROCE"), total shareholders return ("TSR"), earnings per share ("EPS") and gap to competition (until 2022). Since 2021, performance criteria also include a set of three weighted environmental, social and governance ("ESG") indicators representing 30% and 20% award vesting for the Executive Office and Executive Officers, respectively, including health & safety, climate action and diversity & inclusion ("D&I"). For health & safety (10% award vesting for both Executive Office and Executive Officers), the target is to halve the fatality frequency rate versus a defined baseline (the baseline is the adjusted average frequency rate over 5 years before the grant). For D&I (10% and 5% award vesting for Executive Office and Executive Officers, respectively), the target is to reduce by 40% the gap between the Company's 2030 target of having 25% women in management and 2020 baseline. For climate (10% and 5% award vesting for Executive Office and Executive Officers, respectively), the CO2 emission target has been set to be reached by the end of the vesting period. The employees eligible to receive PSUs are a sub-set of the group of employees eligible to receive RSUs.

RSUs granted under the ArcelorMittal Equity Incentive Plan are designed to provide a retention incentive to eligible employees. RSUs are subject to "cliff vesting" after 3 years, with 100% of the grant vesting on the third anniversary of the grant contingent upon the continued active employment of the eligible employee within the Company.

The maximum number of PSUs and RSUs available for grant during any given year is subject to the prior approval of the Company's shareholders at the annual general meeting of shareholders. The 2023 and 2024 Caps for the number of PSUs/RSUs that may be allocated to the Executive Office and other retention and performance based grants below the Executive Office level, were approved at the annual general meetings of shareholders on May 2, 2023 and April 30, 2024, respectively, at a maximum of 3,500,000 shares and 5,500,000 shares, respectively.

Independent auditor's report

Report on the Audit of the Financial Statements

Opinion

We have audited the financial statements of ArcelorMittal S.A. (the "Company"), which comprise the statement of financial position as at December 31, 2024, and the statement of operations and statement of other comprehensive income, the statement of changes in equity and the statement of cash flows for the year then ended, and the notes to the financial statements, including material accounting policy information.

In our opinion, the accompanying financial statements give a true and fair view of the financial position of the Company as at December 31, 2024, and of its financial performance and cash flows for the year then ended in accordance with International Financial Reporting Standards ("IFRS") as adopted by the European Union.

Basis for opinion

We conducted our audit in accordance with EU Regulation N° 537/2014, the Law of 23 July 2016 on the audit profession ("Law of 23 July 2016") and with International Standards on Auditing ("ISAs") as adopted for Luxembourg by the "Commission de Surveillance du Secteur Financier" ("CSSF"). Our responsibilities under the EU Regulation Nº 537/2014, the Law of 23 July 2016 and ISAs as adopted for Luxembourg by the CSSF are further described in the "Responsibilities of the "réviseur d'entreprises agréé" for the audit of the financial statements" section of our report. We are also independent of the Company in accordance with the International Code of Ethics for Professional Accountants, including International Independence Standards, issued by the International Ethics Standards Board for Accountants ("IESBA Code") as adopted for Luxembourg by the CSSF together with the ethical requirements that are relevant to our audit of the financial statements, and have fulfilled our other ethical responsibilities under those ethical requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of the audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Impairment of Investments in Subsidiaries

Description of the Matter The balance of investments in subsidiaries as of December 31, 2024 was \$46,049 million. As disclosed in Note 7 to the financial statements, the Company recorded a net impairment of investments in subsidiaries of \$537 million in 2024.

The Company's evaluation of investments in subsidiaries for impairment involves a comparison of the recoverable amount measured based on the value in use of underlying steel and mining operations with the carrying amount. Key assumptions that had a significant impact on the Company's estimate of the recoverable amounts of investments in subsidiaries, included future volumes of shipments, future selling prices, variable costs and discount rate. Changes in these assumptions could have a significant impact on the recoverable amount of the investments. There are significant judgments made by management to estimate these assumptions, including as it relates to the impact of the war in Ukraine, both specifically on the Company's investments in Ukrainian operations, and more broadly, the impact of the war on the level of uncertainty associated with these assumptions. Furthermore, there are significant judgments made by management to assess the existence of impairment reversal indicator. When such indicator is identified, management also performs an estimate of the recoverable amount of the impaired investments.

The estimate of the recoverable amount also considers the Company's exposure to certain climate related risks, which affect the estimates of the future cash flows. Where there is a legal obligation in terms of carbon neutrality, the estimates of the future cash flows include the decarbonization capital expenditure expected to be necessary to maintain the level of economic benefits expected to be generated by the respective assets in the current condition. For the jurisdictions where there is no legal obligation for carbon neutrality, the decarbonization related uncertainty was reflected in the risk premiums in the discount rates applied to determine the present value of the estimated future cash flows.

Auditing the recoverable amounts of investments in subsidiaries was complex and required a high degree of auditor judgement and an increased extent of effort, including the involvement of valuation specialists, as the amount of investments in subsidiaries and the amount of impairment of investments in subsidiaries are material to the financial statements and due to the significant estimation uncertainty and subjective nature of the assumptions used in the estimates, as described above.

How We Addressed the Matter in Our Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over management's valuation methodology and assumptions used for the estimates of future cash flows of the underlying steel and mining operations, which are directly and indirectly held by the Company and its subsidiaries. For example, we evaluated controls over the Company's forecasting process used to develop the estimated future cash flows and controls over management's data included in the estimated future cash flows.

We evaluated management's ability to reasonably estimate future cash flows by comparing actual results to management's historical forecasts. As it relates to future volume of shipments, future selling prices and variable costs, we compared management's estimates to available external third-party data regarding demand, selling prices and raw material prices. Specifically, as it relates to the estimate of the recoverable amount of investments in subsidiaries which comprise ArcelorMittal Kryvyi Rih CGU (representing the Company's operations in Ukraine), we evaluated the reasonableness of management's assumption as it relates to the timing for the end of war and the length of the post-war recovery period, by independently developing a reasonable range of point estimates and comparing to management's estimate.

With the assistance of our valuation specialists, we evaluated the effects of climate-related matters, including their impact on risk premiums and discount rates by considering, among other factors, current legislation and regulations related to carbon emissions, as well as the Company's ongoing initiatives to transition to lower-carbon operations. Also, as part of our procedures, we compared expected decarbonization capital expenditures against approved budgets and where applicable, costs incurred to date.

With the assistance of our valuation specialists, we evaluated the discounted cash flows methodology and assessed the discount rates used in the value in use estimates, by comparing to underlying source information, testing the mathematical accuracy of the calculation, developing an independent range of estimates and comparing the discount rate selected by management to our range.

We also evaluated the adequacy of the disclosures in Note 7 of the financial statements.

Recoverability of Deferred Tax Assets ("DTAs")

Description of the Matter	The DTA balance as of December 31, 2024, was \$8,390 million. As explained in Note 16 to the financial statements, ArcelorMittal S.A. has DTAs primarily related to tax losses and other tax benefits carried forward. Under current tax law in Luxembourg, tax losses accumulated before January 1, 2017, do not expire and are recoverable against future taxable income. The assessment of the likelihood of future taxable profits being available, and specifically the length of the forecast periods utilized, requires significant management judgment.
	Auditing the recognition of ArcelorMittal S.A.'s DTA balances is subjective because the estimation requires significant judgment, including the availability of future taxable income against which tax deductions represented by the DTA can be offset. In addition, auditing the recognition of DTA balances that are supported by the expectation of future taxable income arising beyond ArcelorMittal S.A.'s 5-year planning horizon required significant auditor's judgment and an increased effort.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's assessment of the recoverability of deferred tax assets. For example, we tested controls over management's review of the significant assumptions used in estimating the projections of future taxable income, including management's analysis of the sensitivity of the length of the forecast periods to change, based on other reasonably likely outcomes that would have a material effect on the recoverability of DTAs.
	To test the recoverability of DTAs, among other procedures, we compared the projections of future taxable income with the actual results of prior periods and, separately, against other forecasted financial information prepared by the Company, such as that used in estimating the recoverable amounts of investments in subsidiaries as described in the 'Impairment of Investments in Subsidiaries' key audit matter above. We assessed the Company's evaluation of the length of the forecast periods to utilize the DTA by independently developing a reasonable range of point estimates and comparing to management's estimate. Additionally, we tested the completeness and accuracy of the existing intragroup loan and external debt agreements used by management to forecast financial income, the primary input to future taxable income, and we performed sensitivity analyses over this forecast. Where relevant and with the assistance of our tax professionals, we also evaluated management's proposed tax planning strategies.

We also evaluated the adequacy of the disclosures in Note 16 of the financial statements in respect of ArcelorMittal S.A.'s DTAs.

Other information

The Board of Directors is responsible for the other information. The other information comprises the information included in the management report and the corporate governance statement but does not include the financial statements and our report of "réviseur d'entreprises agréé" thereon.

Our opinion on the financial statements does not cover the other information and we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report this fact. We have nothing to report in this regard.

Responsibilities of the Board of Directors for the financial statements

The Board of Directors is responsible for the preparation and fair presentation of the financial statements in accordance with IFRS as adopted by the European Union, and for such internal control as the Board of Directors determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

The Board of Directors is also responsible for presenting the financial statements in compliance with the requirements set out in the Delegated Regulation 2019/815 on European Single Electronic Format, as amended ("ESEF Regulation").

In preparing the financial statements, the Board of Directors is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Board of Directors either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Responsibilities of the "réviseur d'entreprises agréé" for the audit of the financial statements

The objectives of our audit are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue a report of the "réviseur d'entreprises agréé" that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with EU Regulation N° 537/2014, the Law of 23 July 2016 and with the ISAs as adopted for Luxembourg by the CSSF will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

As part of an audit in accordance with EU Regulation N° 537/2014, the Law of 23 July 2016 and with ISAs as adopted for Luxembourg by the CSSF, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control.
• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Board of Directors.
• Conclude on the appropriateness of Board of Directors' use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our report of the "réviseur d'entreprises agréé" to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our report of the "réviseur d'entreprises agréé". However, future events or conditions may cause the Company to cease to continue as a going concern.
• Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
• Assess whether the financial statements have been prepared, in all material respects, in compliance with the requirements laid down in the ESEF Regulation.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and communicate to them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our report unless law or regulation precludes public disclosure about the matter.
