Commenting on the results in the first half of 2023, François Jackow, Chief Executive Officer of the Air Liquide Group, stated:

"In a complex and changing macroeconomic and geopolitical environment, Air Liquide delivered, in the first half of the year, a very solid performance characterized by sales growth on a comparable basis and a new increase in its operating margin excluding the energy impact. This performance highlights the resilience and quality of our business model and is in line with the trajectory of our ADVANCE strategic plan.

Revenue reached 13.98 billion euros, an increase of +4.9% on a comparable basis in the first semester. On an as published basis, the year-over-year comparison was -1.6%, due to the drop in energy prices - whose variations are passed on to Large Industries customers - as well as negative currency impacts. The Gas & Services activity, which represented 96% of the Group's revenue, was up +5.3% on a comparable basis. Within this activity, all regions saw growth, in particular the Americas and Europe, driven notably by Industrial Merchant and Healthcare.

In line with its ADVANCE strategic plan, Air Liquide continued the steady improvement of its operational performance. The Group generated significant efficiencies of 206 million euros, up +24% despite an inflationary context unfavorable to savings on purchases, and continued the dynamic management of its business portfolio. Its ability to create value allowed it to adjust its prices in Industrial Merchant while preserving sales volumes. As a result, the operating margin increased further, by +80 basis points excluding the energy impact.

Net profit (Group share) amounted to 1.72 billion euros, up +32% as published. Recurring net profit (1) increased by +11.3% excluding currency impacts. Cash flow (2) grew by +13% excluding currency impacts. The balance sheet is strong with a net debt to equity ratio of 39.2% (3) . Recurring ROCE (4) , which amounted to 10.2% at end-June, remains above 10%, in line with ADVANCE's objectives.

In terms of outlook, the Group's investment momentum remained strong, reflecting our commitment to climate and paving the way for future growth. The project backlog, at 3.5 billion euros, remained high. Investment decisions reached 1.8 billion euros this semester. With more than 40% of projects linked to the energy transition, 12-month investment opportunities are numerous and total 3.4 billion euros.

In 2023, Air Liquide is confident in its ability to further increase its operating margin and to deliver recurring net profit growth, at constant exchange rates (5) ."

Group revenue totaled 13,980 million euros in the 1 st half of 2023, up +4.9% on a comparable basis. Group revenue as published in the 1 st half-year was down -1.6%, impacted by unfavorable energy (-4.7%) and currency (-2.1%) impacts, with the significant scope impact being slightly positive at +0.3%.

Gas & Services revenue amounted to 13,405 million euros during the 1 st half, a comparable increase of +5.3%. Published sales in the 1 st half of 2023 were down slightly by -1.4%, impacted by negative energy and currency impacts of -4.9% and -2.1% respectively, the significant scope impact being limited (+0.3%).

• Gas & Services revenue in the Americas reached 5,159 million euros in the 1 st half of 2023, representing a comparable increase of +6.7%. Sales in the Industrial Merchant business were up sharply, by +10.0%, driven by a high price effect (+7.5%). Customer shutdowns penalized Large Industries sales (-3.9%) while volumes remained solid overall in the US Gulf Coast. In Healthcare, price increases in Proximity Care in the United States and the dynamism of Home Healthcare in Canada and South America were the main contributors to the very strong increase in sales (+13.5%). Lastly, after very solid growth in 2022, revenue from the Electronics business was down by -5.8% in the 1 st half due to the sharp decline in sales of materials in the 2 nd quarter, in a context of slowdown in demand from memory manufacturers.
• Revenue in Europe was up +4.8% on a comparable basis during the 1 st half of 2023 and reached 4,975 million euros. In Industrial Merchant, the very strong increase in sales of +18.1% benefited from a price effect that remained very high at +19.0%. Healthcare sales were up +5.8%, driven notably by the strong development of diabetes treatment in Home Healthcare and higher medical gas prices in response to inflation. Large Industries revenue was down -3.6% in the 1 st half-year, however this was a significant improvement compared to the 2 nd half of 2022 heavily impacted by the sharp increase in energy prices.
• Sales in Asia Pacific were up +3.8% on a comparable basis in the 1 st half of 2023 and amounted to 2,763 million euros. Large Industries revenue, down -5.9%, was impacted in particular by weak demand and customer shutdowns. In Industrial Merchant, the sharp increase in sales of +12.1% was supported by a price effect of +9.2% and a strong increase in volumes in China in the 2 nd quarter. In the Electronics business (+7.3%), after double-digit sales growth in the 1 st quarter, revenue growth was more moderate in the 2 nd quarter (+4.3%).
• Revenue in the Middle East & Africa region increased by +5.8% on a comparable basis to 508 million euros in the 1 st half of 2023. The sales growth in air gases in South Africa and Egypt explained the solid performance of Large Industries. In Industrial Merchant, a high price effect (+8.7%) and the increase in volumes made it possible to fully absorb the impact of the divestiture of businesses in the Middle East and achieve solid sales growth.

Industrial Merchant revenue continued to grow strongly (+12.1%), driven by a high price effect of +10.7% and growing volumes. Large Industries revenue, down -3.6% in a context of weak demand, saw a significant improvement compared to a 2 nd half of 2022 which was heavily impacted by the sharp increase in energy prices, in Europe in particular. Electronics sales were up +6.3% in the half-year: following double-digit growth in the 1 st quarter, revenue growth was more moderate in the 2 nd quarter due to a very high basis of comparison in 2022 and lower demand from memory manufacturers. Lastly, the strong growth in sales in Healthcare (+8.2%) was supported by the increase in the prices of medical gases in an inflationary context and the dynamism of Home Healthcare.

Consolidated revenue from Engineering & Construction totaled 180 million euros in the 1 st half of 2023, down -17.3% compared to the high sales to third-party customers in the 1 st half of 2022. Consolidated revenue does not reflect the volume of activity carried out with internal projects in Large Industries or Electronics. Order intake amounted to 530 million euros, a slight increase compared to the 1 st half of 2022.

Sales in the Global Markets & Technologies business increased by +3.9% on a comparable basis and amounted to 395 million euros in the 1 st half-year. Organic growth reached +17%, excluding several divestitures. Order intake for Group projects and third-party customers reached 496 million euros.

The Group's operating income recurring (OIR) reached 2,481 million euros in the 1 st half of 2023. It was up by +8.5% and +13.0% on a comparable basis, which is significantly higher than the comparable growth in sales of +4.9%.

The operating margin (OIR to revenue) stood at 17.7%, a strong improvement of +80 basis points excluding the energy impact.

Efficiencies ( ) contributed to this improvement in margin. They amounted to 206 million euros, up sharply by +23.6% 1 compared to the 1 st half of 2022 and in line with the annual target of more than 400 million euros.

Net profit (Group share) amounted to 1,722 million euros in the 1 st half of 2023, with an increase as published of +31.9% and +39.5% excluding the currency impact. Excluding the proceeds from the sale of the stake in Hydrogenics, the impairment of an intangible asset and of assets held for sale, net profit recurring (Group share) (2) amounted to 1,627 million euros. This was up by +4.9% and +11.3% excluding currency, compared to net profit recurring (Group share) in the 1 st half of 2022, a significant increase over comparable sales growth of +4.9%. Net earnings per share rose by +32.0% compared with the 1 st half of 2022, in line with the increase in net profit (Group share). These stood at 3.30 euros per share compared with 2.50 euros per share in the 1 st half of 2022.

Cash flows from operating activities before changes in working capital amounted to 3,211 million euros during the 1 st half of 2023, representing a sharp increase of +10.4% and +13.2% excluding the currency impact.

Net debt at June 30, 2023 reached 10,550 million euros, a sharp decrease compared with 12,010 million euros at June 30, 2022 and an increase of 289 million euros compared with December 31, 2022, following the payment of more than 1.6 billion euros in dividends in May.

The return on capital employed after tax (ROCE) was 10.0% for the 1 st half of 2023. At 10.2%, recurring ROCE (3) remained above the target of 10.0% in the Advance strategic plan, and was up sharply by +50 basis points compared to the 1 st half of 2022.

In order to accelerate the decarbonization of its production units, Air Liquide announced in the 1 st half of 2023 the signing of long-term renewable energy supply contracts (PPAs) for more than 1,000 GWh per year. This will equate to a reduction of its annual CO² emissions by approximately -970,000 tonnes.

In the 1 st half of 2023, industrial and financial investment decisions amounted to 1,798 million euros. They were stable compared to the very high level of the 1 st half of 2022.

At 3.5 billion euros, the investment backlog remained at a very high level for three quarters and posted a strong increase compared to the 3.0 billion euros in the 1 st half of 2022.

The additional contribution to sales of unit start-ups and ramp-ups totaled 139 million euros over the 1 st half of 2023. Over full-year 2023, it is expected to be at the low end of the range of 300 to 330 million euros previously communicated.

At 3.4 billion euros, the 12-month portfolio of investment opportunities remained very high at the end of June 2023. This reflects the dynamism of project developments, particularly in the energy transition, representing more than 40% of the portfolio, as well as in the Electronics business.

The Air Liquide Board of Directors met on July 26, 2023. During this meeting, the Board reviewed the consolidated financial statements ending June 30, 2023. Limited review procedures were completed with respect to the consolidated interim financial statements, and an unqualified review report is in the process of being issued by the statutory auditors.

Americas

Gas & Services revenue in the Americas reached 5,159 million euros in the 1 st half of 2023, representing an increase of +6.7%. Sales in the Industrial Merchant business were up sharply, by +10.0%, driven by a high price effect (+7.5%). Customer shutdowns penalized Large Industries sales (-3.9%) while volumes remained solid overall in the US Gulf Coast. In Healthcare, price increases in Proximity Care in the United States and the dynamism of Home Healthcare in Canada and South America were the main contributors to the very strong increase in sales (+13.5%). Lastly, after very solid growth in 2022, revenue from the Electronics business was down by -5.8% in the 1 st half due to the sharp decline in sales of materials in the 2 nd quarter, in a context of slowdown in demand from memory manufacturers.

• Revenue from Large Industries was down -3.9% in the 1 st half-year, affected by customer shutdowns in the region and the divestiture of the activity in Trinidad and Tobago. In the United States, sales of cogeneration units were solid and gas volumes resilient, particularly in the 2 nd quarter.
• Sales in the Industrial Merchant business posted a strong increase of +10.0% in the 1 st half-year. The price effect remained high at +7.5% in an inflationary context, down slightly sequentially in the 2 nd quarter (+5.3%). Volumes increased, in particular those of bulk, supported notably by the Manufacturing, Construction and Research markets.
• In the Healthcare business, sales increased sharply by +13.5% in the 1 st half of 2023. Rising prices in Proximity Care in the United States, the dynamism of

Americas Gas & Services H1 2023 Revenue

Home Healthcare in Canada, particularly for the treatment of sleep apnea, and the development of the Medical Gases and Home Healthcare businesses in Latin America were the main drivers of this strong growth.

■ Electronics posted a decrease of -5.8% in revenue in the 1 st half-year. The sharp decline in volumes in specialty and advanced materials was partially offset by higher sales in Equipment & Installation, while Carrier Gas revenue remained stable.

Europe

Revenue in Europe was up +4.8% during the 1 st half of 2023 and reached 4,975 million euros. In Industrial Merchant, the very strong increase in sales of +18.1% benefited from a price effect that remained very high at +19.0%. Healthcare sales were up +5.8%, driven notably by the strong development of diabetes treatment in Home Healthcare and higher medical gas prices in response to inflation. Large Industries revenue was down -3.6% in the 1 st half-year, however this was a significant improvement compared to a 2 nd half of 2022 heavily impacted by the sharp increase in energy prices.

• Revenue from Large Industries was down -3.6% in the 1 st half-year, however a strong improvement compared to sales that were down -22% in the 2 nd half of 2022 due to the sharp rise in energy prices. Customer demand strengthened in the 1 st half-year in a context of lower energy prices and sales benefited from the start-up of a new Air Separation Unit (ASU) in Poland at the beginning of the year. Hydrogen volumes progressed in the 2 nd quarter in Refining. The level of activity in the 2 nd quarter was broadly stable compared to the 1 st quarter.
• In the Industrial Merchant business, sales growth remained extremely strong, at +18.1%, supported by a price effect of +19.0%, still very high, with a slight sequential decrease in the 2 nd quarter (+16.4%). Volumes increased excluding helium and liquefied CO² (whose supply was restricted for several

Europe Gas & Services H1 2023 Revenue

months). They benefited in particular from sustained demand in the Automotive and Metallurgy sectors.

■ Revenue from Healthcare increased by +5.8% in the 1 st half-year. Diabetes treatment was the largest contributor to the strong growth in Home Healthcare sales, followed by sleep apnea. Growth in Medical Gases revenue was supported by rising prices in an inflationary context. Growth in Specialty Ingredients sales remained dynamic, with a strong contribution from price increases associated with raw material cost inflation.

• Air Liquide and Holcim have signed a Memorandum of Understanding (MoU) to pursue a project to decarbonize Holcim's new cement production plant under development in Belgium, using Air Liquide proprietary Cryocap TM carbon capture innovative technology. The joint funding request was selected by the European Union Innovation Fund.
• Air Liquide will implement for Verallia, in Italy, a customized solution allowing to reduce CO² emissions and energy consumption. The furnace will use the oxy-combustion process and the HeatOx TM proprietary technology to recover the heat.
• Air Liquide announced the construction of an industrial scale ammonia (NH3) cracking pilot plant in the port of Antwerp, Belgium. When transformed into ammonia, hydrogen can be easily transported over long distances. Using innovative technology, this plant will make it possible to convert, with an optimized carbon footprint, ammonia into hydrogen.

Asia Pacific

Sales in Asia Pacific were up +3.8% in the 1 st half of 2023 and amounted to 2,763 million euros. Large Industries revenue, down -5.9%, was impacted in particular by weak demand and customer shutdowns. In Industrial Merchant, the sharp increase in sales of +12.1% was supported by a price effect of +9.2% and a strong increase in volumes in China in the 2 nd quarter. In the Electronics business (+7.3%), after double-digit sales growth in the 1 st quarter, revenue growth was more moderate in the 2 nd quarter (+4.3%).

• Sales in Large Industries were down -5.9% in the 1 st half-year, with trends observed at the beginning of the year continuing in the 2 nd quarter. Demand thus remained low, particularly in air gases for the Steel industry in Japan and in Chemicals. Sales were also impacted by customer maintenance turnarounds, including one extended stoppage in China.
• Industrial Merchant revenue was up sharply by +12.1%. The price effect stood at a very high level of +9.2% in the 1 st half-year, with particularly strong price increases in Japan and Australia. In China, after the beginning of the year was marked by a wave of covid-19, volumes rose sharply from March, with the comparison effect also favorable in the 2 nd quarter. In the region, the

Asia Pacific Gas & Services H1 2023 Revenue

Manufacturing, Food and Technology sectors supported the increase in volumes.

■ Sales in the Electronics business were up by +7.3% in the 1 st half-year. Following double-digit growth in the 1 st quarter, revenue growth was more moderate in the 2 nd quarter due to a very high basis of comparison in 2022 and lower demand from memory manufacturers. Sales of materials were down, while Carrier Gas revenue was up sharply, supported by the start-up and ramp-up of new units and by the increase in the price of helium. After a very strong increase in the 1 st quarter, Equipment & Installation sales were stable in the 2 nd quarter compared to a high level in 2022.

Asia Pacific

• Air Liquide has signed a long-term Power Purchase Agreement (PPA) with subsidiaries of China Three Gorges, allowing access to solar and wind farms of a total production capacity of 200 MW. This agreement will enable up to 120,000 tonnes of CO² emission reduction per year. Following PPAs signed in the United States, Europe and South Africa, this is the first long-term PPA signed by Air Liquide in China.
• Air Liquide will invest in China around 60 million euros to revamp two Air Separation Units (ASUs) in order to use electrical energy instead of steam, hence significantly reducing the CO² emissions. This investment is performed within the frame of a long term supply contract renewal with Tianjin Bohua Yongli Chemical Industry CO., Ltd (YLC).

Middle East and Africa

Revenue in the Middle East & Africa region increased by +5.8% to 508 million euros in the 1 st half of 2023. The sales growth in air gases in South Africa and Egypt explained the solid performance of Large Industries. In Industrial Merchant, a high price effect (+8.7%) and the increase in volumes made it possible to fully absorb the impact of the divestiture of businesses in the Middle East and achieve solid sales growth. In the Healthcare business, the development of diabetes treatment in Saudi Arabia and the contribution of an acquisition in South Africa were the main drivers of the strong growth in Home Healthcare.

Middle East and Africa

■ In the first half, Air Liquide and Sasol announced the signing of long-term Power Purchase Agreements (PPAs) with Enel Green Power, TotalEnergies and its partner Mulilo for the Sasol site at Secunda in South Africa.

• In May 2023, Future Proof Shipping (FPS) launched the world's first hydrogen-powered container barge. "H2 Barge 1" transports goods between the port of Rotterdam (Netherlands) and the region of Antwerp (Belgium) on behalf of the sports equipment manufacturer Nike. Air Liquide actively contributed to this project with the supply of hydrogen and the development of a specific storage system.

OPERATING INCOME RECURRING

Operating income recurring before depreciation and amortization totaled 3,710 million euros, an increase of +6.8% and +9.3% excluding the currency impact compared with the 1 st half of 2022.

Purchases were down significantly by -10.3% excluding currency impacts, due to the decrease in energy costs. Other purchasing items were up slightly in an inflationary environment. Personnel costs increased by +8.3% excluding currency impacts in a context of sustained inflation. Other operating income and expenses increased by +12.2% excluding currency impacts and notably included an increase in maintenance costs and to a lesser extent travel costs, the level of which nevertheless remained lower than in 2019.

Depreciation and amortization amounted to 1,229 million euros, an increase of +4.5% excluding the currency impact, reflecting the impact of the start-up of new units.

The Group's operating income recurring (OIR) reached 2,481 million euros in the 1 st half of 2023. It was up by +8.5% and +13.0% on a comparable basis, which is significantly higher than the comparable growth in sales of +4.9%. The operating margin (OIR to revenue) stood at 17.7%, a strong improvement of +80 basis points excluding the energy impact. The increase was +160 basis points as published thanks to the accretive effect linked to the decrease in energy costs contractually passed through to Large Industries customers.

Efficiencies ( ) contributed to this improvement in margin. They amounted to 206 million euros, up sharply by +23.6% 4 compared to the 1 st half of 2022 and in line with the annual target of more than 400 million euros. These efficiencies represent a saving of 1.9% of the cost base. Industrial efficiencies increased and accounted for more than 50% of the total. They included energy efficiency and production optimization projects in Large Industries and supply chain improvements in Industrial Merchant. The Group's digital transformation continued: in Large Industries with the connection of new units to remote operation centers (Smart Innovative Operations, SIO), in Industrial Merchant with the implementation of tools to optimize delivery routes for bulk and, increasingly, cylinders, and in Healthcare with the

Operating income recurring in the Americas reached 1,029 million euros over the 1 st half of 2023, an increase of +6.2% as published. Excluding the energy impact, the operating margin increased by +10 basis points compared with the 1 st half of 2022. This improvement was supported by the increase in the Industrial Merchant business margin, which benefited from higher prices and volumes and the high level of efficiencies. In the Electronics business, the significant decline in sales of advanced materials with high added value, and in Large Industries, the costs resulting from customer shutdowns, had an unfavorable impact on the margin, which partially offset the positive contribution of Industrial Merchant.

Operating income recurring in Europe amounted to 846 million euros, an increase as published of +9.7% compared with the 1 st half of 2022. Excluding the energy impact, the operating margin improved very significantly by +100 basis points compared with the 1 st half of 2022. The contribution of the Industrial Merchant business was significant, with higher prices and efficiencies supporting the increase in the operating margin. The efficiencies generated in the Healthcare activity also contributed to the improvement in the margin.

In Asia Pacific, operating income recurring stood at 611 million euros, an increase as published of +7.7%. Excluding the energy impact, the operating margin improved by +170 basis points compared with the 1 st half of 2022. This improvement was supported by the increase in the Industrial Merchant business margin, which benefited from higher

prices and the high level of efficiencies, and by an increase in prices in Electronics, particularly helium and rare gases. The payment of an indemnity by a Large Industries customer also contributed to this improvement.

Operating income recurring for the Middle East and Africa region amounted to 101 million euros, representing an increase of +5.2% as published compared with the 1 st half of 2022. Excluding the energy impact, the operating margin was down by -320 basis points compared with the 1 st half of 2022. The introduction of re-invoicing to the customer for the costs of the energy consumed by the 17 units at the Secunda site in South Africa had a highly dilutive effect on the margin ( ) . 5

Engineering & Construction

Operating income recurring for Engineering & Construction amounted to 18 million euros in the 1 st half of 2023, or 10.0% of sales, in line with medium-term business objectives.

Global Markets & Technologies

Operating income recurring for Global Markets & Technologies stood at 64 million euros, an increase of +29.3% as published compared with the 1 st half of 2022. The operating margin reached 16.2%, a very sharp increase of +330 basis points compared with the 1 st half of 2022. This performance was supported by high efficiencies and the accretive effect on the margin of the recent activities divestitures.

Research & Development and Corporate costs

Research & Development expenses and Corporate costs totaled 188 million euros, stable compared with the 1 st half of 2022.

NET PROFIT

Other operating income and expenses showed a positive net balance of 33 million euros. Other operating expenses amounted to -172 million euros and included in particular the impairment of an intangible asset and of assets held for sale (these two items having no cash impact) and, to a lesser extent, restructuring costs. Other operating income amounted to 205 million euros and mainly included the sale of the Group's stake in Hydrogenics.

The financial result totaled -211 million euros compared to -180 million euros in the 1 st half of 2022. This includes net finance costs of -118 million euros, down -22.5% excluding currency impact due to the decrease in average outstanding debt and to the proceeds generated by the early redemption of bonds in US dollars. The average net finance cost of 3.3% was higher than in the 1 st half of 2022 (3.0%). The average net finance cost does not include the exceptional income related to the early redemption of bonds denominated in US dollars. Other financial income and expenses stood at -93 million euros compared with -36 million euros in the 1 st half of 2022. This sharp increase is due to a provision for interest on arrears and the impact of the increase in interest rates on pension obligations.

The tax expense was 539 million euros, an effective tax rate of 23.4%, lower than in the 1 st half of 2022 (25.0%), mainly due to a reduced tax rate on the capital gain on the divestiture of the Group's stake in Hydrogenics.

The share of profit of associates amounted to 2 million euros. The share of minority interests in net profit totaled 44 million euros, down -39.6%, mainly due to the impairment of an intangible asset.

Net profit (Group share) amounted to 1,722 million euros in the 1 st half of 2023, with an increase as published of +31.9% and +39.5% excluding the currency impact. Excluding the proceeds from the sale of the stake in Hydrogenics, the impairment of an intangible asset and of assets held for sale, net profit recurring (Group share) (6)

Extra-financial performance

In order to accelerate the decarbonization of its production units, Air Liquide announced in the 1 st half of 2023 the signing of long-term renewable energy supply contracts (PPAs) for more than 1,000 GWh per year. This will equate to a reduction of its annual CO² emissions by approximately -970,000 tonnes. The Group has also decided to build a pilot industrial-scale ammonia cracking unit to enrich its portfolio of low-carbon hydrogen production solutions.

The European Commission granted subsidies to 2 new carbon capture projects in Germany and Belgium. They will enable Group customers in the cement and lime sectors to reduce their emissions by 2.6 million tonnes of CO² per year.

Air Liquide has partnered with Lotte Chemical in South Korea and TotalEnergies in Europe to create joint ventures that will invest primarily in hydrogen filling centers and refueling stations for heavy vehicles. The Group has also signed a partnership with Iveco to develop hydrogen mobility in Europe, with a first refueling station having been inaugurated in the south of France. Air Liquide is thus very actively involved in the decarbonization of mobility.

Importantly, an additional "scope 3" objective and new biodiversity commitments were also announced in the first half of 2023.

Sustainable development

• Aware of the importance of contributing to the achievement of carbon neutrality throughout its value chain and the importance of its customer relationships, the Group made a pledge that 75% of its 50 largest customers will have a stated carbon neutrality commitment by 2025 and 100% by 2035.
• New biodiversity objectives:
  • o Air Liquide committed to submit a set of engagements towards biodiversity conservation to Act4nature International.
  • o Air Liquide committed to develop and implement an aggregated biodiversity KPI by 2025, allowing the Group to monitor and communicate on its biodiversity performance. This will be defined in 2023 and be deployed thereafter.
  • o Air Liquide committed to reinforce its biodiversity assessment criteria into the investment process for all new projects by 2024.

INVESTMENT CYCLE

INVESTMENT DECISIONS AND INVESTMENT BACKLOG

In the 1 st half of 2023, industrial and financial investment decisions amounted to 1,798 million euros. They were stable compared to the very high level of the 1 st half of 2022.

Industrial investment decisions reached 1,771 million euros in the 1 st half of 2023, an increase over the 1,738 million euros in investments decided in the 1 st half of 2022. The Electronics business continued to grow, notably with the signature of long-term contracts for new carrier gas production units in the United States and Asia, and the investment in a new production site for advanced materials in Asia. In Industrial Merchant, 2 nd quarter decisions include in particular three nitrogen generators for a customer manufacturing batteries in the United States, in addition to the five nitrogen generators decided in the 1 st quarter in China. Within the Global Markets & Technologies business, the development of hydrogen mobility continues in China and Korea with investment decisions in hydrogen filling centers and their logistics chain.

Financial investment decisions totaled 27 million euros in the 1 st half of 2023. They include seven acquisitions in Industrial Merchant in China, the United States, Italy and India to intensify the density of our local presence and thus profitability of the businesses. They also include the acquisition of a Home Healthcare company in Sweden and a company that designs and manufactures innovative equipment for Hydrogen mobility.

At 3.5 billion euros, the investment backlog remained at a very high level for three quarters and posted a strong increase compared to the 3.0 billion euros in the 1 st half of 2022. The breakdown of the investment backlog is balanced between Large Industries and Electronics. These investments should lead to a future contribution to annual sales of approximately 1.2 billion euros per year after full ramp-up of the units.

START-UPS

In the 1 st quarter, three large Air Separation Units (ASUs) for Large Industries customers started up in Europe and the United States. In the 2 nd quarter, three carrier gas units also started up for Electronics customers in China and Japan, as well as a unit for the assembly of integrated circuits in secondary electronics in the Industrial Merchant business in Vietnam.

The additional contribution to sales of unit start-ups and ramp-ups totaled 139 million euros over the 1 st half of 2023. Over full-year 2023, it is expected to be at the low end of the range of 300 to 330 million euros previously communicated.

INVESTMENT OPPORTUNITIES

At 3.4 billion euros, the 12-month portfolio of investment opportunities remained very high at the end of June 2023. This reflects the dynamism of project developments, particularly in the energy transition, representing more than 40% of the portfolio, as well as in the Electronics business. The distribution of opportunities is well-balanced between Americas, supported by the Inflation Reduction Act and the Chips Act, Europe, where large electrolyzer and carbon capture projects are in the advanced development phase, Asia, with projects in Large Industries and Electronics, and lastly, the Middle East. The portfolio beyond 12 months includes other significant projects related to the Inflation Reduction Act and the Chips Act in the United States and the energy transition in Europe and Canada.

RISK FACTORS

There was no change in risk factors during the first half. Risk factors are described in the 2022 Universal Registration Document on pages 76 to 94.

OUTLOOK

In a complex and changing macroeconomic and geopolitical environment, Air Liquide delivered, in the first half of the year, a very solid performance characterized by sales growth on a comparable basis and a new increase in its operating margin excluding the energy impact. This performance highlights the resilience and quality of its business model and is in line with the trajectory of the ADVANCE strategic plan.

Revenue reached 13.98 billion euros, an increase of +4.9% on a comparable basis in the 1 st semester. On an as published basis, the year-over-year comparison was -1.6%, due to the drop in energy prices - whose variations are passed on to Large Industries customers - as well as negative currency impacts. The Gas & Services activity, which represented 96% of the Group's revenue, was up +5.3% on a comparable basis. Within this activity, all regions saw growth, in particular the Americas and Europe, driven notably by Industrial Merchant and Healthcare.

In line with its ADVANCE strategic plan, Air Liquide continued the steady improvement of its operational performance. The Group generated significant efficiencies of 206 million euros, up +24% despite an inflationary context unfavorable to savings on purchases, and continued the dynamic management of its business portfolio. Its ability to create value allowed it to adjust its prices in Industrial Merchant while preserving sales volumes. As a result, the operating margin increased further, by +80 basis points excluding the energy impact.

Net profit (Group share) amounted to 1.72 billion euros, up +32% as published. Recurring net profit ( ) increased by 9 +11.3% excluding currency impact. Cash flow ( ) grew by +13% excluding currency impact. The balance sheet is 10 strong with a net debt to equity ratio of 39.2% ( ) . Recurring ROCE ( ) , which amounted to 10.2% at end-June, remains 11 12 above 10%, in line with ADVANCE's objectives.

In terms of outlook, the Group's investment momentum remained strong, reflecting its commitment to climate and paving the way for future growth. The project backlog, at 3.5 billion euros, remained high. Investment decisions reached 1.8 billion euros this semester. With more than 40% of projects linked to the energy transition, 12-month investment opportunities are numerous and total 3.4 billion euros.

In 2023, Air Liquide is confident in its ability to further increase its operating margin and to deliver recurring net profit growth, at constant exchange rates ( ) . 13

• Comparable sales change and comparable operating income recurring change
• Operating margin and operating margin excluding energy impact
• Recurring net profit Group share

• Recurring ROCE

DEFINITION OF CURRENCY, ENERGY AND SIGNIFICANT SCOPE IMPACTS

Since industrial and medical gases are rarely exported, the impact of currency fluctuations on activity levels and results is limited to euro translation impacts with respect to the financial statements of subsidiaries located outside the eurozone. The currency impact is calculated based on the aggregates for the period converted at the exchange rate for the previous period.

In addition, the Group passes on variations in the cost of energy (electricity and natural gas) to its customers via indexed invoicing integrated into their medium and long-term contracts. This indexing can lead to significant variations in sales (mainly in the Large Industries Business Line) from one period to another depending on fluctuations in prices on the energy market.

An energy impact is calculated based on the sales of each of the main subsidiaries in Large Industries. Their consolidation allows the determination of the energy impact for the Group as a whole. The foreign exchange rate used is the average annual exchange rate for the year N-1. Thus, at the subsidiary level, the following formula provides the energy impact, calculated for natural gas and electricity respectively:

Energy impact =

Share of sales indexed to energy year (N-1) x (Average energy price in year (N) - Average energy price in year (N-1))

This indexation effect of electricity and natural gas does not impact the operating income recurring.

The significant scope impact corresponds to the impact on sales of all acquisitions or disposals of a significant size for the Group. These changes in scope of consolidation are determined:

• for acquisitions during the period, by deducting from the aggregates for the period the contribution of the acquisition,
• for acquisitions during the previous period, by deducting from the aggregates for the period the contribution of the acquisition between January 1 of the current period and the anniversary date of the acquisition,
• for disposals during the period, by deducting from the aggregates for the previous period the contribution of the disposed entity as of the anniversary date of the disposal,
• for disposals during the previous period, by deducting from the aggregates for the previous period the contribution of the disposed entity.

Note: exceptionally, the acquisition of Sasol air separation units in 2021 had an impact in 2 steps on Group sales. After the acquisition of the assets in June 2021 (1 st step), devices were installed on the units in 2022 in order to measure the energy consumed which, from October 2022 (2 nd step), could be re-invoiced to the customer according

to the standard Large Industries contractual frame. For the sake of transparency in financial communication, sales related to energy consumed and contractually re-invoiced to the customer are identified within the significant scope and are therefore excluded from the comparable growth. This element will thus be accounted for in the significant scope during 12 months from October 2022.

OPERATING MARGIN AND OPERATING MARGIN EXCLUDING ENERGY IMPACT

The operating margin is the ratio of the operating income recurring divided by revenue. The operating margin excluding energy impact corresponds to the operating income recurring (not affected in absolute value by the cost of energy contractually re-invoiced to Large Industries customers) divided by revenue excluding the energy impact to which is attached the corresponding currency impact. The ratio of operating income recurring divided by the revenue (whether restated or not from the energy impact) is calculated with rounding to one decimal place. The variation between 2 periods is calculated as the difference between these rounded ratios, which can result in positive or negative differences compared to a more precise calculation, due to rounding.

NET PROFIT EXCLUDING IFRS16 AND NET PROFIT RECURRING EXCLUDING IFRS16

Net Profit excluding IFRS16:

	H1 2022	FY 2022	H1 2023
(A) Net Profit as Published	1,377.6	2,903.9	1,765.6

(A) - (B) = Net Profit excluding IFRS16	1,384.8	2,919.5	1,772.7

(1) The IFRS16 impact includes the reintegration of leasing expenses less depreciation and other financial expenses booked in relation to IFRS16

Net Profit Recurring excluding IFRS16:

	H1 2022	FY 2022	H1 2023
(A) Net Profit as Published	1,377.6	2,903.9	1,765.6
(B) Exceptional and significant transactions after-tax with no impact on OIR	(245.8)	(402.9)	70.2
(A) - (B) = Net Profit recurring	1,623.4	3,306.8	1,695.4
(1) (C) IFRS16 Impact	(7.2)	(15.6)	(7.1)
(A) - (B) - (C) = Net Profit recurring excluding IFRS16	1,630.6	3,322.4	1,702.5

(1) The IFRS16 impact includes the reintegration of leasing expenses less depreciation and other financial expenses booked in relation to IFRS16

Nota: the fact that the impaired intangible asset is on the balance sheet of a company with minority interests explains the difference between the amount of significant and non-recurring items after tax taken into account in the calculation of recurring net profit Group share and the amount considered in the calculation of non-recurring ROCE (based on 100% recurring net income excluding IFRS 16).

EFFICIENCIES

Efficiencies represent a sustainable cost reduction resulting from an action plan on a specific project. Efficiencies are identified and managed on a per project basis. Each project is followed by a team composed in alignment with the nature of the project (purchasing, operations, human resources...).

RETURN ON CAPITAL EMPLOYED - ROCE

Return on capital employed after tax is calculated based on the Group's consolidated financial statements, by applying the following ratio for the period in question.

For the numerator: net profit excluding IFRS16 - net finance costs after taxes for the period in question. For the denominator: the average of (total shareholders' equity excluding IFRS16 + net debt) at the end of the past three half-years.
