Foreword

The Interim Financial Report at September 30, 2025 has been prepared in compliance with Article 154-ter, paragraph 5, of Legislative Decree 58 of February 24, 1998, with the clarification indicated in the following section, and in conformity with the recognition and measurement criteria set out in the international accounting standards (International Accounting Standards - IAS and International Financial Reporting Standards - IFRS) issued by the International Accounting Standards Board (IASB), as well as the interpretations of the International Financial Reporting Interpretations Committee (IFRIC) and the Standing Interpretations Committee (SIC), recognized in the European Union pursuant to Regulation (EC) no. 1606/2002 and in effect as of the close of the period.

Article 154-ter, paragraph 5, of the Consolidated Financial Intermediation Act, as amended by Legislative Decree 25/2016, no longer requires issuers to publish an interim financial report at the close of the 1st and 3rd Quarters of the year. The new rules give CONSOB the power to issue a regulation requiring issuers, following an impact analysis, to publish periodic financial information in addition to the annual and semi-annual financial reports. In view of the foregoing, Enel intends to continue voluntarily publishing an interim financial report at the close of the 1st and 3rd Quarters of each year in order to satisfy investor expectations and conform to consolidated best practice in the main financial markets, while also taking due account of the quarterly reporting requirements of a number of major listed subsidiaries.

The Enel Group structure is organized into a matrix that comprises:

Global Business Lines

Global Business Lines, which are responsible for managing and developing assets, optimizing their performance and the return on capital employed in the various geographical areas in which the Group operates (Italy, Iberia and ROW - Rest of the World). In compliance with safety, protection and environmental policies and regulations, they are tasked with maximizing the efficiency of the processes they manage and applying best international practices, sharing responsibility for EBITDA, cash flows and revenue with the countries.

The Group, which also draws on the work of an Investment Committee,1 benefits from a centralized industrial vision of projects in the various business lines. Each project is assessed not only on the basis of its financial return but also in relation to the best technologies available at the Group level. Furthermore, each business line contributes to guiding Enel's leadership in the energy transition and in the fight against climate change, managing the associated risks and opportunities in its area of competence. The following provides a brief summary of the primary objectives of each Global Business Line:

  • Global Energy and Commodity Management and Chief Pricing Officer: optimizes the Group's margin through the active management of its hedging strategy and the exposure to commodity risk, taking account of all commercial/market factors in order to maximize the integrated margin in the markets in which we operate through the optimization of gas and fuel supplies, and local dispatching of thermal and renewables generation, while supporting Enel X Global Retail in defining the commercial strategy;
  • Enel Green Power and Thermal Generation: provides guidance for a rapid and effective energy transition, growing the portfolio of renewables generation facilities, and manages the corresponding evolution of thermal generation and storage assets with a view to decarbonizing our energy mix in order to meet the needs of customers in all the countries in which we operate; manages the operation and maintenance of Group generation plants in compliance with applicable policies and regulations governing safety, protection and the environment;
  • Enel Commercial: defines the commercial and marketing strategy and manages the customer product range for energy, products and services, including electric mobility up to the sale through the various commercial channels, ensuring compliance with safety, protection and environmental regulations, maximizing value for the customer and operational efficiency, and supporting margin optimization with Global Energy and Commodity Management. Manages the entire customer journey, from activation to billing and support, with the aim of improving customer satisfaction and value while optimizing the cost of service and cash flow. Maximizes operational excellence and customer centricity by exploring new service models to improve productivity and effectiveness, driving the transformation needed to ensure long-term competitiveness.

Reference scenario

The macroeconomic environment

The nine months of 2025 confirm a stabilization of the global economy, despite the slowdown in international trade, new tensions on tariffs and a more uncertain geopolitical context. Global growth kept a moderate pace, supported by services and more favorable financial conditions than at the start of the year. Industry showed signs of recovery, albeit uneven across areas and sectors, while after a first half of resilient consumption, global demand was affected by a slowdown in trade and lower push for investments. Although far from the peaks of 2023, inflation remains persistent in several countries, especially in the services component.

In the euro area, the nine months of the year showed modest growth, held back by the weak performance of manufacturing and declining external demand. Consumption benefited from the gradual improvement in purchasing power and the decline in energy prices, but business confidence remained fragile. In the 3rd Quarter, euro-area headline inflation stood at 2.1% on an annual basis, supported by the decline in energy and food prices, while core inflation decreased more slowly due to service costs and wage rigidity. After cutting interest rates by 0.25 percentage points at its June meeting, the European Central Bank kept them unchanged over the summer, with the deposit rate at 2%, against a backdrop of gradual disinflation and still weak activity.

In the United States, the labor market showed signs of cooling accompanied by a more contained consumption dynamic. Industrial production held up, supported by private investment and a strong technology sector, but trade suffered from tariff increases. In the 3rd Quarter, US headline inflation is estimated to stand at 2.9% on an annual basis, supported by service prices and rising housing costs. After the July cut, the Federal Reserve cut its key interest rates further by 0.25 percentage points in September, bringing the target range to 4.00-4.25%, showing greater confidence in the disinflation process but caution in the face of still-present wage pressures.

In Latin America, economic trends were mixed in the 3rd Quarter of 2025, with signs of a slowdown in a context of cautious monetary policies and a delicate balance between supporting growth and controlling inflation.

In Argentina, GDP is estimated to have increased by 3.2% on an annual basis, down from 6.3% in the previous quarter, while average quarterly inflation is expected at 34.8%, down sharply from 43.4% in the 2nd Quarter.

In Brazil, GDP is expected to grow by 1.9% in the 3rd Quarter, slightly down from 2.2%, with average quarterly inflation at 5.1%, down moderately from 5.4% in the previous quarter. The central bank maintains a cautious stance, progressing towards containing inflation and the expected start of a gradual rate cut cycle by the end of the year.

In Colombia, GDP growth is expected to increase to 3.0% from 2.1% in the previous quarter, supported by expansionary fiscal policy and real wage growth. Inflation remained under pressure, with an average quarterly growth of 5.1%, slightly above the 5.0% in the previous three months, while expectations of rising prices prompted the central bank to keep key interest rates unchanged from its May 2025 meeting.

In Chile, economic activity confirmed signs of moderate growth in the 3rd Quarter, with GDP expected to increase by 2.0% on an annual basis, supported by rising private real incomes. Inflation fell in the last six months of the year, allowing the central bank to start a cycle of rate cuts in July. The mining sector benefited from recovering copper prices and increased demand from Asia.

Energy conditions

The commodity market

The nine months of 2025 continued to be characterized by overall weakness in the oil market. Weak global demand, weighed down by subdued growth in China and the economic slowdown in Europe, did not provide support to prices, with the average price of Brent at about $70 a barrel, down from $81.7 a barrel in the same period of the previous year. The average price fell further to $68 a barrel in the 3rd Quarter, reflecting oversupply on the market, while new voluntary cuts announced by producing countries failed to stabilize prices.

European gas prices also showed decreasing trends. In the 3rd Quarter of 2025, the average TTF price was €32.4/MWh, down from €35.3/MWh in the same period of 2024. The decrease was driven by continuous weakness of industrial demand and rapidly filling European storage facilities, which offset the impact of Asian competition for LNG. Nevertheless, the January-September 2025 average price was €38.3/MWh, up from €31.4/MWh in the same period of 2024, reflecting ongoing geopolitical tensions and the higher demand recorded in winter.

The European API2 coal index continued its stabilization phase in 2025, with a January-September 2025 average price of $100.6/ton, down from $110.4/ton in the same period of 2024. In the 3rd Quarter of 2025, the average price was $98.9/ton, down from $114.3/ ton in the same period of 2024. This trend reflects the persistent weakness of electricity demand in Europe, supported by renewables growth and high storage levels, while supply remains abundant despite some temporary logistical restrictions.

The average CO2 price in the nine months of 2025 was €72.4/ton, up from €64.9/ton in the same period of 2024 (€76/ton in the 3rd Quarter of 2025, up from €67/ton in the same period of 2024), supported by the progressive tightening of the European ETS

{17}------------------------------------------------

system, with decreasing emissions cap and fewer free allowances available, in addition to expectations linked to the CBAM (Carbon Border Adjustment Mechanism) and the inclusion of new sectors.

In the nine months of 2025, base metal prices recorded an overall increasing trend. Copper benefited from supply disruptions and demand driven by the energy transition, while aluminum benefited from Chinese production restrictions and tougher environmental policies. Prices increased for both metals also in the 3rd Quarter, reflecting both a cyclical recovery in industrial demand and the effect of trade tensions following the introduction of 50% tariffs on steel and aluminum by the United States as well as new tariffs on copper. These developments contributed to further fueling volatility, consolidating an upward trend in prices over the course of 2025.

In the 3rd Quarter of 2025 electricity demand in Italy decreased slightly compared with the same period of 2024 (-3.8%), reflecting both the slowdown in economic activity and lower demand for cooling in the months of July and August. By contrast, demand in Spain grew by 2.5%, thanks to solid economic momentum. In the nine months of 2025, compared to the same period

in 2024, diverging trends are confirmed. Demand decreased in Italy by 1.2%, but increased by 3.2% in Spain.

In Latin America, data for the 3rd Quarter of 2025 show significant growth in Colombia (+3.8%) and, to a lesser extent, Chile (+1.4%) and Brazil (+0.3%). In Argentina, however, demand is slightly down (-0.6%).

Natural gas demand in Italy decreased in the 3rd Quarter of 2025, mainly reflecting the decline in thermal generation (-12.4%). Considering the nine months of the year, the balance is still positive compared to 2024, with widespread growth in all sectors, driven in particular by the increase in demand for thermal generation (+4.0%), especially in the first months of the year.

Significant events in the 3rd Quarter of 2025

Enel agrees on a €756 million multiborrower and multicurrency financing with EIFO and Citi

On July 25, 2025, the Group signed an agreement aimed at granting multicurrency facilities from Citi and Denmark's Export and Investment Fund (EIFO), for up to €756 million. The first facility for $500 million (equivalent to around €430 million) was signed by Enel Finance International (EFI).

Enel finalizes the agreement to purchase Cetasa, owner of a portfolio of wind plants and wind projects in Spain

On July 31, 2025, Enel announced that Enel Green Power España SLU, a Group subsidiary controlled through Endesa, finalized an agreement to buy 37.5% and 25% of the capital of Cetasa from Caja Rural de Soria and Caja Rural de Navarra, respectively. Cetasa is the owner of a 99 MW portfolio of operating wind plants in the province of Soria, plus a further 30 MW in wind projects under development. Following the agreement, Enel Green Power España SLU increased its interest in Cetasa to 100%. The enterprise value on a 100% basis recognized in the agreement is equal to €60 million.

Enel Américas SA approved a share buyback program

On July 31, 2025, the Board of Directors of the Chilean listed subsidiary Enel Américas SA approved the call of an Extraordinary Shareholders' Meeting held on August 28, 2025 to resolve on the approval of a share buyback program, regarding a maximum of 4% of Enel Américas' share capital, with a duration of 90 days from the date of the Shareholders' Meeting.

The Board of Directors meeting immediately after the Extraordinary Shareholders' Meeting set the purchase price for the share buyback at $105.23, equal to the weighted average price over the 90 days prior to July 30, 2025, plus a 15% premium.

The transaction was finalized on October 1, 2025, with a total outlay of €421 million. Following the transaction, the Group increased its interest in Enel Américas SA from 82.27% to 85.71%.

Enel launches a share buyback program of up to €1 billion to pay additional remuneration to shareholders

On July 31, 2025, in implementation of the resolution of the Shareholders' Meeting of May 22, 2025, the Company's Board of Directors approved the launch of a share buyback program for a total outlay of up to €1 billion and a maximum number of shares not exceeding 495 million in any case, equivalent to approximately 4.87% of Enel's share capital.

The program, extending from August 1 until no later than December 31, 2025, is aimed at providing shareholders a remuneration in addition to the distribution of dividends, as a result of the cancellation of treasury shares purchased for this purpose. For the purposes of executing the program, Enel appointed an authorized intermediary who can make decisions on the purchases in full independence, also in relation to their timing, and in accordance with daily price and volume limits consistent with both the authorization granted by the Shareholders' Meeting of May 22, 2025, and with the provisions of Article 5 of Regulation (EU) 596/2014 and Article 3 of Delegated Regulation (EU) 2016/1052.

The cancellation of the treasury shares purchased under the program is carried out without reduction of the share capital, in accordance with the resolution of the Shareholders' Meeting of May 22, 2025, and by means of several deeds in a fractional manner.

As of September 30, 2025 Enel has purchased shares for a total €631 million and holds 91,622,961 treasury shares, equal to about 0.9012% of share capital.

{20}------------------------------------------------

On September 24, 2025, Enel Finance International NV, the finance company controlled by Enel SpA, launched a multi-tranche bond for institutional investors in the US and international markets for a total $4.5 billion, equivalent to about €3.8 billion. The issue, guaranteed by Enel, was around 3 times oversubscribed, with total orders for approximately $14.4 billion. The issue was structured in four tranches with settlement date at September 30, 2025, and had an average duration of approximately 12 years and an average cost equivalent in euros of about 3.6%.

The proceeds of the issuance are expected to be used in order to fund the Group's ordinary financing needs, including refinancing of maturing debt.

Net electricity generated by Enel in the nine months of 2025 decreased by 6.09 TWh on the same period of 2024 (-4.1%).

The decrease reflected a decline in output from traditional sources (-2.29 TWh), attributable to decreased recourse to coal-fired plants (-0.64 TWh), combined-cycle plants (-1.48 TWh) and fuel oil and turbogas plants (-0.17 TWh) mainly in Italy, Colombia and Peru, (the latter following the disposal of a number of generation companies).

Renewables generation decreased (-3.51 TWh) mainly reflecting a decrease in hydroelectric generation (-3.43 TWh) mainly in Italy, Chile, Argentina, Brazil and Peru, partly offset by an increase in generation in Colombia and Spain (the latter following the acquisition of 34 hydro plants), wind generation (-1.44 TWh) mainly in Spain, the United States, Chile, Italy and Peru, and geothermal, biomass and biogas generation (-0.16 TWh), partly offset by an increase in solar generation (1.52 TWh) mainly in Brazil, Italy, Colombia and North America.

Nuclear generation declined by 0.29 TWh.

Excluding the changes attributable to the above-mentioned disposals of generation assets in Peru during the nine months of 2024 (3.19 TWh) and the acquisition in 2025 of 34 hydro plants and a number of wind plants in Spain (-1.14 TWh), electricity generation in the nine months of 2025 decreased by 4.04 TWh (-2.8%) over the same period of 2024.

NET ELECTRICITY GENERATION BY SOURCE (NINE MONTHS OF 2025)

The Group's total net efficient consolidated capacity increased to 86.3 GW, from 83.8 GW at the end of 2024, reflecting the acquisition in Spain of 34 hydro plants from the Acciona Group and a portfolio of wind plants from Caja Rural de Soria and Caja Rural de Navarra (0.7 GW), a new thermal combined-cycle plant in Italy (0.8 GW), the increase in Battery Energy Storage System (BESS) capacity in Italy (0.5 GW) and higher solar capacity (0.5 GW).

  • (3) The figure for 2024 was restated following an update of the calculation method from LTM (last twelve months) to YTD (year-to-date).

Electricity transported on Enel's distribution grid in the nine months of 2025 came to 355.7 TWh, down 7.6 TWh (-2.1%) on the same period of 2024, mainly reflecting the sale of distribution assets in Peru (-3.7 TWh) and in a number of municipalities in the provinces of Milan and Brescia in Italy (-6.6 TWh).

Thus, excluding the effects of the above-mentioned changes in the scope of consolidation in the two periods under review, electricity distribution increased by 2.7 TWh (+0.8%), mainly reflecting an increase in volumes transported in Spain (+3.3 TWh).

The number of Enel end users with active smart meters at September 30, 2025 increased by 108,198, mainly reflecting increases in Brazil (+734,551), Spain (+82,401), Chile (+3,603) and Colombia (+13), partly offset by decreases in Italy (-712,267) and Argentina (-103).

The number of Enel end users at the end of the nine months of 2025 decreased by 218,944 on the same period of 2024 (-0.3%). The decrease is mainly attributable to the already mentioned disposal of distribution assets in the provinces of Milan and Brescia in Italy (-718,387), only partly offset by increases in the Rest of the World (+422,322), mainly in Latin America, and Spain (+77,121).

Foreword

In light of the Group ongoing reorganization and the finalization of the divestment program in 2024, the table below reports financial information as prepared for management purposes, in order to provide a consistent and comparable representation of the Group performance and allow a better understanding of underlying developments.

The information, prepared on the basis of "like-forlike" management data, reflects the changes in the consolidation scope in application of the Group strategy to focus on core countries and business lines, as if these had been in place since the beginning of the period.

{27}------------------------------------------------

At September 30, 2025, Group revenue came to €59,702 million, up 3.6% from €57,634 million in the corresponding period of 2024.

The increase on like-for-like basis is equal to €4,097 million and mainly reflects higher revenue from the Thermal Generation and Trading business, with the sale of commodity on the wholesale market, within a framework of rising average prices compared with the same period of 2024, as well as the increase in revenue from the transport of electricity and gas, mainly in Italy, and in retail revenue in Spain. These factors have more than offset the decrease in retail revenue in Italy, connected to the repositioning in the customer portfolio, which led to a decrease in average rates applied and a decrease in volumes in the top and corporate segments.

As commented above for revenue, costs also increased in the period ended September 30, 2025, mainly reflecting the increase in prices of energy commodities, in particular gas in Italy, which impacted on fair value measurement of gas purchase contracts with physical settlement closed in the nine months of 2025.

Costs in the period also include the charges relating to the finalization of the sale of a residual interest in Slovenské elektrárne due to the release in profit or loss of negative equity reserves in respect of that company (€341 million).

Moreover, following a new organizational arrangement, the performance and financial data of the 3SUN subsidiary were reallocated from Enel Green Power to the Holding and Services Business Line.

Ordinary gross operating profit decreased by €187 million (-1.1%) compared with the same period of 2024. Excluding the effects commented in the foreword, and considering like-for-like operating figures, the ordinary gross operating profit increased by €153 million and also reflects the effects of adverse exchange rate developments (for a total €355 million), mainly in Brazil (€152 million), Colombia (€75 million) and Argentina (€73 million).

Net of these changes, the like-for-like ordinary gross operating profit increased by €508 million, thanks to the performance of Integrated Businesses in Spain and Enel Grids in Italy, as a result of the strong acceleration of investment, implemented starting from 2023. These effects more than offset the decrease in the retail segment in Italy with the normalization of the offering portfolio for retail customers and the decrease in quantities sold.

Gross operating profit/(loss)

Gross operating profit came to €16,870 million (€18,595 million in the nine months of 2024), a decrease of €1,725 million, mainly reflecting the effects mentioned in relation to ordinary gross operating profit, as well as the recognition, in the nine months of 2024, of income from the sale of electricity generation and distribution assets in Peru (€1,347 million) and charges for extraordinary solidarity levies in Spain (€202 million). These effects were compounded by the recognition in the 2nd Quarter of 2025 of charges relating to the finalization of the sale of a residual interest in Slovenské elektrárne due to the release in profit or loss of negative equity reserves in respect of that company (€341 million).

In addition to the factors commented above, operating profit also includes the impairment losses essentially relating to a number of renewable generation assets in the United States (€68 million) and Chile (€31 million).

Group ordinary profit/(loss)

Group ordinary profit in the period ended September 30, 2025 amounted to €5,703 million, from €5,846 million in the same period of 2024.

Considering like-for-like data (for the reasons detailed in the foreword) the Group ordinary profit increased by €248 million, essentially reflecting the factors already commented for ordinary operating profit, as well as the decrease in net financial charges (€315 million), relating to the decrease in net debt in the periods under review and in the average cost of debt.

{31}------------------------------------------------

Group profit/(loss)

Group profit came to €5,236 million in the period ended September 30, 2025, a decrease of €634 million from €5,870 million in the corresponding period of 2024, mainly reflecting the different incidence of the sale of assets in the periods under review. More specifically, profit in the nine months of 2024 includes gains, net of tax and non-controlling interest, from the sale of generation and distribution assets in Peru (€428 million), while in the same period in 2025 it includes charges of €341 million reflecting the sale of 50% of Slovak Power Holding and the release of negative equity reserves relating to the company.

The following table provides a reconciliation of Group profit with Group ordinary profit, indicating the non-recurring items and their respective impact on performance, net of the associated tax effects and non-controlling interests.

Net capital employed at September 30, 2025 came to €107,323 million and was funded by €49,788 million in equity attributable to owners of the Parent and non-controlling interests and €57,535 million in net financial debt. At September 30, 2025 the debt/ equity ratio was 1.16 (1.13 at December 31, 2024). The increase in net capital employed (€2,385 million) mainly reflected:

• the increase in net working capital (up €4,012 million), mainly reflecting the decrease in trade payables, mainly in Italy, Spain and Chile, and in net payables to institutional market operators in Italy, partly offset by a decrease in trade receivables mainly in Italy, Spain and Chile;

• the decrease in net non-current assets in the amount of €1,164 million mainly due to the decrease in property, plant and equipment and intangible assets, essentially attributable to depreciation and amortization recognized for the period and adverse exchange rate developments,

{33}------------------------------------------------

which more than offset the effect of capital expenditure in the period and of the acquisition in Spain of hydro plants from the Acciona Group and wind plants from Caja Rural de Soria and Caja Rural de Navarra;

• the decrease in net assets held for sale (€101 million) mainly reflecting the reclassification of the assets of Enel Generación Piura under assets "held for use" (€204 million), since they no longer meet the requirements of IFRS 5, net of the reclassification under assets available for sale of a number of US renewable generation assets and associated liabilities included in the asset swap agreement with Gulf Pacific Power (€125 million).

Total equity at September 30, 2025 increased by €617 million mainly reflecting the profit for the period (€4,415 million) and the increase in the reserve for perpetual hybrid bonds (€1,074 million). These increases were partly offset by the distribution of dividends (€3,499 million including the coupons paid to holders of hybrid bonds) and the decrease in the reserve related to the buyback transaction launched by Enel SpA (€1,000 million).

{34}------------------------------------------------

Net financial debt amounted to €57,535 million at September 30, 2025, not including at September 30, 2025 the net financial debt of net assets classified as held for sale for a total €49 million, an increase of €1,768 million from €55,767 million at December 31, 2024.

The funding needs generated by capital expenditure in the period (€6,522 million, net of grants received equal to €314 million), the payment of dividends (€5,859 million including €240 million in coupons paid to holders of hybrid bonds), the acquisition of hydro and wind plants by Endesa (€979 million, net of cash and cash equivalents acquired) and the buyback of treasury shares by Enel SpA and Endesa (€1,073 million), as well as the effects on debt relating to new leases (€395 million), were only partly offset by the cash flows generated by operating activities (€9,093 million), the issuance of perpetual hybrid bonds net of repayments in the nine months of 2025 (€1,074 million) and positive effects of exchange rate developments on debt (€2,870 million). At September 30, 2025, the debt/equity ratio was 1.16 (1.13 at December 31, 2024).

Gross financial debt came to €69,208 million at September 30, 2025, a decrease of €1,954 million compared with December 31, 2024.

- sustainable financing 44,127 1,373 45,500 45,650 2,549 48,199
Sustainable financing/Totalgross debt (%) 66% 68%

More specifically, gross long-term financial debt (including the short-term portion) amounted to €67,238 million, of which €44,127 million in sustainable financing, and is structured as follows:

  • bonds in the amount of €48,084 million, of which €29,641 million in sustainability-linked bonds, an increase of €484 million on December 31, 2024, reflecting new bond issues by Enel Finance International including a multi-tranche sustainability-linked issue in February 2025, equal to €2,000 million, and a multi-tranche issue in September 2025, equal to $4,500 million (equivalent to about €3,800 million). The increase was partly offset by redemptions in the period and positive exchange rate developments;

  • bank borrowings in the amount of €16,004 million, of which €14,487 million in sustainability-linked fi-

  • nancing, a decrease of €493 million on December 31, 2024;

  • other borrowings in the amount of €3,150 million, a decrease of €256 million on December 31, 2024.

Gross short-term financial debt amounted to €1,970 million, down by €1,689 million on December 31, 2024, mainly reflecting a reduction in commercial paper issues and cash collateral, equal to €1,159 million and €535 million, respectively.

Cash and cash equivalents and short- and long-term financial assets amounted to €11,673 million, a decrease of €3,722 million on December 31, 2024 mainly reflecting the decrease in "cash and cash equivalents with banks and short-term securities" of €3,234 million.

{35}------------------------------------------------

Cash flows

Cash flows from operating activities in the nine months of 2025 was a positive €9,093 million, an increase of €700 million on the corresponding period of the previous year, reflecting the decrease in cash requirements connected with the payment of taxes, interest and other financial expense, and cash requirements connected with changes in net working capital essentially in line with the same period of 2024.

Cash flows used in investing activities in the nine months of 2025 absorbed cash in the amount of €7,471 million, compared with €2,953 million in the nine months of 2024, essentially reflecting a decrease in cash flows from disposals of businesses or business units (€4,178 million). In the nine months of 2025, disposals of businesses or business units (€53 million) include a price adjustment from the sale in 2024 of 90% of Duereti Srl to A2A SpA (€24 million), the sale of Wind Autogeneración in Colombia (€13 million), the sale of Arroyo Solar in the United States (€14 million) and the price adjustment of €2 million on the sale of 50% of Enel Green Power Australia. In the nine months of 2024, the amount of €4,231 million mainly referred to:

  • the sale by Enel Green Power North America (EGPNA) of the entire interest held in a number of renewables companies for €249 million net of cash and cash equivalents sold of €4 million;
  • the sale of the entire interest held by Enel Perú SAC in generation companies Enel Generación Perú SAA and Compañía Energética Veracruz SAC to Niagara Energy SAC for a total of €1,100 million net of cash and cash equivalents sold of €98 million;
  • the sale by Enel Perú SAC of equity stakes held in Enel Distribución Perú SAA and Enel X Perú SAC to North Lima Power Grid Holding SAC for a total of €2,865 million net of cash and cash equivalents sold of €15 million.

Moreover, in the nine months of 2025, investments in companies or business units came to €979 million and included €949 million for the acquisition of the entire capital of Corporación Acciona Hidráulica SL by Endesa Generación net of cash and cash equivalents acquired of €10 million and €30 million for the acquisition of 62.5% of Compañía Eólica Tierras Altas SA by Enel Green Power España net of cash and cash equivalents acquired of €14 million.

Investments in property, plant and equipment, intangibles and non-current contract assets came to €6,838 million in the nine months of 2025, of which €2 million classified as held for sale, a decrease from €7,790 million in the same period of the previous year. Capital grants came to €314 million (€587 million in the nine months of 2024).

Cash flows from/(used in) other investing activities in the nine months of 2025 came to €21 million and mainly reflects the cash outflow for the capital increase of Enel Green Power Australia in the amount of €130 million following the agreement between Potentia Energy and CVC DIF and Cbus Super for the acquisition of a controlling interest in a portfolio of over 1 GW of renewable assets. The effect was only partly offset by minor divestments mainly in Italy, Spain, North America and Latin America.

Cash flows from financing activities absorbed liquidity for a total €4,605 million, compared with €4,220 million in the nine months of 2024, mainly reflecting:

  • the change in net financial debt (as the net balance between repayments, new borrowings and other changes) of €1,246 million;
  • distribution of dividends in the amount of €5,619 million, plus €240 million paid to holders of hybrid bonds;
  • the issue of hybrid bonds in the amount of €1,974 million with repayments of €900 million;
  • the purchase of own shares by Endesa in the amount of €442 million and Enel SpA in the amount of €631 million.

In the nine months of 2025 cash flow used in investing activities in the amount of €7,471 million and cash flow from financing activities of €4,605 million totally absorbed the cash flows from operating activities, a positive €9,093 million. The remainder therefore decreased cash and cash equivalents at September 30, 2025 by €3,239 million (including €256 million associated with developments in the exchange rates of local currencies against the euro).

Total(1) 6,836 7,602 (766) -10.1%

(1) Does not include €2 million regarding units classified as held for sale (€188 million in the nine months of 2024).

Capital expenditure amounted to €6,836 million in the nine months of 2025, a decrease of €766 million compared with the same period of 2024.

The decrease reflects a different approach to investment selection, with greater focus on operational plants ("brownfield") in order to maximize financial return and profitability.

In this respect, if the acquisitions of 34 hydroelectric plants in Spain for €961 million and of a portfolio of wind plants for €46 million are included in brownfield investments, total capex in the period increased by €241 million compared to the same period of the previous year.

Group capital expenditure is mainly focused on grids (€4,738 million, 69% of the total) and renewable energy (€1,053 million, 15% of the total), in line with the Group's Strategic Plan.

Capital expenditure in distribution activities increased

by €579 million to ensure continuous improvement in service reliability and quality, enhance the resilience of grids to extreme climate events as well as to maximize return on investment. More specifically, the increases were concentrated in Italy, Spain, Brazil, Chile and Argentina.

Regarding renewable energy, the decrease of €1,167 million, excluding the impact of the brownfield investments mentioned above, mainly concerned activities in North America (€582 million), Brazil (€265 million), Italy (€218 million), Chile (€173 million) and Spain (€57 million), only partly offset by increased investments in Colombia (€125 million), South Africa (€8 million) and Panama (€4 million).

Capital expenditure in End-user Markets decreased by €125 million, mainly in Italy and Spain. Capital expenditure by Thermal Generation and Trading decreased by €106 million mainly in Italy.

Performance by Segment

The representation of performance by Segment presented here is based on the approach used by management in monitoring Group performance and communicating it to the markets, taking account of the Group operational model.

The business line is therefore the main discriminant in the analyses performed and decisions taken by the management of the Enel Group, and is fully consistent with the internal reporting prepared for these purposes since the results are measured and evaluated first and foremost for each business line and only thereafter are they broken down by geographical area. In this regard, note that starting with the presentation of the performance of Segments in 2025, management deemed appropriate, also in line with the regulatory systems of the various countries, to include the results of some activities in Latin America, previously allocated to the End-user Markets Business Line, under energy distribution operations of the Enel Grids Business Line. In application of a new organizational arrangement, management also decided to reallocate the performance and financial data of the 3SUN subsidiary from Enel Green Power to the Holding and Services Business Line. Following the new allocation, the figures of the corresponding period of 2024 have been restated for comparative purposes.

Thermal and nuclear generation in the nine months of 2025 decreased by 2,573 million kWh compared with the same period of 2024. The decrease of 642 million kWh in coal-fired generation is mainly attributable to Colombia due to higher resort to hydro generation. The decrease in generation by combined-cycle and fuel-oil and turbo-gas plants of 1,481 million kWh and 171 million kWh, respectively, is essentially attributable to the effects of the sale in the 1st Half of 2024 of Enel Generación Perú (871 million kWh) as well as a decrease in generation in Italy.

The decrease of €161 million in ordinary gross operating profit is mainly attributable to the reduction in thermal power generation in Italy, the effect of which is partly offset by the increase in average prices and volumes sold on the wholesale market in Spain commented earlier. Excluding changes in the consolidation scope due to the disposal in 2024 of traditional generation assets in Peru, the decrease of the ordinary gross operating profit came to €123 million.

Gross operating profit came to €2,038 million (€2,586 million in the nine months of 2024), down by €548 million. Specifically, the decrease reflects the business factors commented above, changes in the consolidation scope in the two periods under review and different developments of non-recurring items. These were a negative €343 million in 2025 and a positive €44 million in 2024. More specifically, non-recurring items in 2025 mainly included charges connected with the release of equity reserves following the disposal of an interest in Slovenské elektrárne (€341 million) in the 2nd Quarter of 2024, while in 2024 non-recurring items related to the gains from the sale of assets in Peru.

In the nine months of 2025 total net power generation decreased compared with the same period of 2024, reflecting lower hydro, wind and geothermal generation, only partly offset by higher solar generation.

The decrease in hydroelectric generation is mainly attributable to the sale of renewables generation assets in Peru in the 2nd Quarter of 2024 (1,819 million kWh), and most notably to lower generation in several countries, with a significant impact in Italy (1,509 million kWh), Chile (1,682 million kWh), Argentina (628 million kWh) and Brazil (481 million kWh), partly offset by higher power generation in Colombia and Central America (1,678 million kWh), Iberia (994 million kWh) and Mexico (12 million kWh).

Wind generation decreased mainly in Iberia (588 million kWh), the United States (530 million kWh), Peru (238 million kWh, reflecting the disposals in the 1st Half of 2024), Chile (127 million kWh), Brazil (109 million kWh) and Italy (86 million kWh). The decrease was partly offset by higher generation in Mexico (286 million kWh).

Solar generation posted an increase, mainly in the United States (1,575 million kWh), Brazil (485 million kWh), Colombia (313 million kWh) and Italy (295 million kWh), driven by the entry in operation of new plants in 2024. The increase was partly offset by the decrease in generation in Chile (459 million kWh) and Iberia (372 million kWh), and Peru (257 million kWh), the latter due to the change in consolidation scope commented earlier.

The ordinary gross operating profit in the nine months of 2025 decreased by €501 million compared with the same period of 2024.

The decrease came to €389 million on like-for-like basis, considering that the ordinary gross operating profit for the nine months of 2024 also reflects the contribution of renewable generation assets in Peru sold in the 2nd Quarter of 2024.

The change is essentially attributable to lower hydro generation in Italy and Chile, lower tax partnership gains in the United States (€281 million), as well as adverse exchange rate developments (€135 million). These negative effects were only partly offset by improved margins in the United States due to the increase in solar generation and in Colombia due to higher hydro generation.

The gross operating profit came to €5,111 million (€5,685 million in the nine months of 2024), a decrease of €574 million mainly reflecting the factors already commented for the ordinary gross operating profit and the recognition in the nine months of 2024 of €65 million from the sale of renewables generation assets in Peru.

The decrease in the ordinary operating profit reflects the factors already commented for the ordinary gross operating profit as well as higher depreciation due to new plants entering into operation, mainly in Italy and the United States.

The decrease of €876 million in the operating profit compared with the nine months of 2024 is attributable to the factors commented earlier in relation to the gross operating profit, as well as higher depreciation and impairment losses in the nine months of 2025, including the impairment loss on a number of assets in Chile (€31 million) and the United States (€68 million).

Capital expenditure in the nine months of 2025, not including the acquisition of already operating plants ("brownfield"), decreased by €1,167 million on the same period of the previous year. The decrease was mainly attributable to assets in North America (€582 million), Brazil (€265 million), Italy (€218 million), Chile (€173 million) and Spain (€57 million), and was only partly offset by higher capital expenditure recognized in Colombia and Central America (€130 million). The decrease reflects a different approach to investment selection, with a greater focus on brownfield plants to maximize financial return and profitability. In this respect, if the acquisition in Spain of 34 hydroelectric plants for €961 million and a portfolio of wind plants for €46 million is included in brownfield investments, capex in the period decreased by €160 million on the same period of the previous year.

In the nine months of 2025 electricity transported on Enel's grid decreased by 2.1% essentially reflecting the sale of distribution assets in Italy in respect of a number of municipalities in the provinces of Milan and Brescia in December 2024 (-6.6 TWh) and the sale of distribution assets in Peru in the 1st Half of 2024

(-3.7 TWh). These effects were only partly offset by higher volumes handled in Spain.

Excluding the effects of these disposals, electricity transported on Enel's grid increased by 2.7 TWh on the same period of the previous year.

Ordinary gross operating profit in the nine months of 2025 increased by €319 million on the same period of 2024.

The increase came to €499 million on a like-for-like basis, considering that the ordinary gross operating profit of the nine months of 2024 also reflected the contribution of distribution assets in Peru and in a number of municipalities in the provinces of Milan and Brescia, respectively sold in the 2nd and 4th Quarter of 2024.

This increase is mainly attributable to Italy, due to the strong acceleration of investments implemented

{59}------------------------------------------------

as from 2023, and to Argentina reflecting rate increases in the period. The ordinary gross operating profit was affected by adverse exchange rate developments (€225 million) in the two periods under review.

Gross operating profit came to €6,522 million (€7,484 million in the nine months of 2024), down €962 million reflecting the recognition in the same period of 2024 of gains from the sale of distribution assets in Peru in the amount of €1,288 million, only partly offset by the period factors commented above for ordinary gross profit.

The decrease in quantities of electricity sold on the free market in the nine months of 2025 mainly regards the business-to-business (B2B) customer segment. The most significant decrease concentrated in Italy with the adoption of a sales strategy focused on the consumer and small business segments*,* and regarded both the free and regulated markets, also reflecting, in the latter, regulatory developments culminating in the elimination of the enhanced protection market from July 1, 2024.2 In Other countries the decrease reflected the change in consolidation scope after the sale of assets in Peru.

Ordinary gross operating profit in the nine months of 2025 increased by €66 million on the same period of 2024, mainly in Spain due to the increase in revenue commented earlier and in the United States reflecting the contribution of demand response capacity and the repositioning towards more profitable businesses. The increase was only partly offset by lower margins in Italy, reflecting the decrease in sales in the retail market commented earlier and the normalization of rates applied to end consumers.

Excluding €11 million related to the sale of assets in Peru, the increase of like-for-like ordinary gross operating profit came to €77 million.

Gross operating profit came to €3,343 million (€3,277 million in the corresponding period of 2024), up €66 million due to the factors commented above.

The increase in ordinary operating profit essentially reflects the factors commented earlier in relation to ordinary gross operating profit, including the decrease in depreciation, amortization and impairment losses recognized in the period (€1,046 million in the nine months of 2025 from €1,315 million in the same period of 2024). More specifically, lower writedowns on trade receivables in Italy and Spain were only partly offset by the increase in amortization charges connected to the capitalization of customer acquisition costs, mainly in Italy and Spain.

The operating profit in the nine months of 2025 came to €2,297 million (€1,899 million in the corresponding period of 2024), reflecting the factors commented earlier in relation to gross operating profit and the decrease in depreciation, amortization and impairment losses, including value adjustments of €83 million recognized in the nine months of 2024 on a number of companies operating in battery storage business in North America.

The change in the ordinary operating loss in the nine months of 2025 compared to the same period of 2024 reflects the decrease in the ordinary gross operating loss, partly offset by the increase of depreciation, amortization and impairment losses in the amount of €9 million.

The operating loss decreased by €284 million, reflecting the factors commented in relation to the gross operating loss and the increase in depreciation and amortization.

Definition of performance measures

In order to present the performance of the Group and analyze its financial structure, separate reclassified schedules have been prepared that differ from the schedules envisaged under the IFRS-EU adopted by the Group and contained in the consolidated financial situation at September 30, 2025. These reclassified schedules contain different performance measures from those obtained directly from the consolidated financial situation, in line with the ESMA Guidelines on Alternative Performance Measures (ESMA/2015/1415) published on October 5, 2015. Management believes that these measures are useful in monitoring the performance of the Group and representative of the financial performance and position of our business.

With regard to those measures, on April 29, 2021, CONSOB issued warning notice no. 5/2021, which gives force to the Guidelines issued on March 4, 2021, by the European Securities and Markets Authority (ESMA) on disclosure requirements under Regulation (EU) 2017/1129 (the Prospectus Regulation), which took effect on May 5, 2021 and replace the references to the CESR Recommendations and those contained in Communication no. DEM/6064293 of July 28, 2006 regarding the net financial position. In particular, the Guidelines update the previous CESR Recommendations (ESMA/2013/319, in the revised version of March 20, 2013).

The Guidelines are intended to promote the usefulness and transparency of alternative performance measures included in regulated information or prospectuses within the scope of application of Directive 2003/71/EC in order to improve their comparability, reliability and comprehensibility.

In line with the regulations cited above, the criteria used to construct these measures for the Enel Group are the following.

Gross operating profit (EBITDA): an operating performance indicator, calculated as the sum of "Operating profit" and "Depreciation, amortization and other impairment" included in "Costs".

Ordinary gross operating profit (ordinary EBITDA): de-

fined as "Gross operating profit" from core businesses connected with the Ownership, Partnership and Stewardship business models with which the Group operates. It does not include a number of charges connected with the disposal of joint control operations not attributable to the Group's core business operations, costs connected with corporate restructurings, costs associated with the resolution of disputes from previous years, compensation related to the sale of controlling interests and extraordinary solidarity levies imposed by local foreign governments on energy companies.

Ordinary operating profit: defined starting from "Operating profit" excluding the effects of transactions not connected with core operations referred to with regard to ordinary gross operating profit. It also excludes significant impairment losses (including reversals of impairment losses) on assets and/or groups of assets following an assessment of the recoverability of their carrying amount under the provisions of "IAS 36 - Impairment of assets" or "IFRS 5 - Non-current assets held for sale and discontinued operations".

Group ordinary profit: it is determined by adjusting "Group profit" for the items discussed under "Ordinary operating profit", taking account of any tax effects and non-controlling interests. Also excluded are a number of operating value adjustments regarding equity-accounted investments and financial components not strictly attributable to the Group's core business operations.

Net non-current assets: calculated as the difference between "Non-current assets" and "Non-current liabilities" with the exception of:

  • "Deferred tax assets" included in "Other non-current assets";
  • "Other non-current financial assets included in net financial debt" included in "Other non-current financial assets";
  • "Long-term borrowings";

{72}------------------------------------------------

  • "Provisions for risks and charges (non-current portion)" included in "Sundry provisions and deferred tax liabilities";
  • "Deferred tax liabilities" included in "Sundry provisions and deferred tax liabilities";
  • "Other non-current financial liabilities included in net financial debt" included in "Other non-current liabilities".

Net working capital: calculated as the difference between "Current assets" and "Current liabilities" with the exception of:

  • "Other current financial assets included in net financial debt" included in "Other current financial assets";
  • "Cash and cash equivalents";
  • "Short-term borrowings and current portion of long-term borrowings";
  • "Provisions for risks and charges (current portion)" included in "Other current liabilities";
  • "Other current financial liabilities included in net financial debt" included in "Other current liabilities".

Net assets held for sale: calculated as the algebraic sum of "Assets classified as held for sale" and "Liabilities included in disposal groups classified as held for sale".

Net capital employed: calculated as the sum of "Net non-current assets", "Net working capital", "Provisions for risks and charges (non-current and current portions)", "Employee benefits", "Deferred tax liabilities" and "Deferred tax assets", as well as "Net assets held for sale".

Net financial debt: a financial structure indicator, determined by:

  • "Long-term borrowings", "Short-term borrowings and current portion of long-term borrowings", and the items "Other non-current financial liabilities included in net financial debt" and "Other current financial liabilities included in net financial debt" respectively included in "Other non-current liabilities" and "Other current liabilities";
  • net of "Cash and cash equivalents";
  • net of "Current financial assets included in net financial debt", which includes: (i) current loan assets; (ii) the current portion of long-term loan assets and (iii) current securities;
  • net of "Other non-current financial assets included in net financial debt", which includes: (i) loan assets and (ii) non-current securities.

More generally, the net financial debt of the Enel Group is reported in accordance with Guideline 39, issued on March 4, 2021 by ESMA, applicable as from May 5, 2021, and with the above warning notice no. 5/2021 issued by CONSOB on April 29, 2021.

Main changes in the consolidation scope

In the two periods under comparison, the consolidation scope changed as a result of a number of transactions. For more information, please see note 3 of the notes to the consolidated financial situation at September 30, 2025.

Outlook

In the nine months of 2025 the Group recorded strong performance that underscores the effectiveness of the strategy set out in the 2025-2027 Strategic Plan presented in November 2024 with a strategy mainly focused on flexible capital allocation in core countries, with the aim of increasing investments in regulated assets with solid and predictable returns.

The Plan is based on three pillars:

  • profitability, flexibility and resilience pursuing value creation through selective capital allocation to optimize the risk/return profile, while keeping a flexible approach;
  • effectiveness and efficiency pursuing the continuous optimization of processes, activities and the product and services portfolio, strengthening cash generation and developing innovative solutions to increase the value of existing assets;
  • financial and environmental sustainability to maintain a solid structure, ensure the flexibility needed for growth and address the challenges of climate change.

The Strategic Plan for 2025-2027 provides for a total gross capex of about €43 billion, an increase of about €7 billion compared with the previous Plan, allocated as follows:

  • €26 billion in Grids, to improve the resilience, digitalization and efficiency of the distribution network. The Group will also continue its advocacy efforts to promote regulatory frameworks that support the central role of grids in the energy transition;
  • €12 billion in Renewable Generation, with a flexible capital allocation and a selective approach aimed at maximizing returns and minimizing risks, also taking advantage of brownfield opportunities, with the aim of further improving profitability. Over the Plan period, we expect to add approximately 12 GW of capacity, with an improved technology mix that includes over 70% onshore wind and programmable technologies (hydro and batteries), reaching a total installed renewable capacity of about 76 GW in 2027;

• €2.7 billion in the Retail segment to enhance integrated bundled offers and improve customer and service management.

As a result of these strategic actions, in 2027 Group ordinary EBITDA is expected to grow to between €24.1 and €24.5 billion and Group net ordinary income is expected to increase to between €7.1 and €7.5 billion.

Shareholders remuneration provides for:

  • a dividend policy based on a minimum fixed dividend per share (DPS) of €0.46 for the 2025-2027 period, with a potential increase up to a 70% payout on net ordinary income;
  • the launch of a share buyback program extending from August 1, 2025 to no later than December 31, 2025 – aimed at granting shareholders additional remuneration, in addition to the distribution of dividends resulting from the cancellation of the shares purchased for this purpose, for a total disbursement of up to €1 billion and a maximum number of shares in any case not exceeding 495 million.

In 2025 Enel plans:

  • investments in distribution grids focusing on geographical areas with a more balanced and clearer regulatory framework;
  • selective investments in renewables**,** aimed at maximizing the return on invested capital and minimizing risks;
  • active management of the customer portfolio through bundled multi-play offers.

In light of the solid performance registered in the nine months of 2025 and business developments in the last Quarter of 2025, we can confirm the guidance provided to the financial markets on the presentation of the 2025-2027 Strategic Plan with a Group ordinary EBIT-DA in the range of between €22.9 and €23.1 billion; the Group net ordinary income for 2025 is expected be slightly above the high end of the guidance range of between €6.7 and €6.9 billion.

In February 2026, the new Strategic Plan of the Group will be presented to the financial community.

  1. Report on Operations

2. Consolidated financial situation at September 30, 2025

Notes to the consolidated financial situation at September 30, 2025

1. Accounting policies and measurement criteria

The accounting standards adopted, the recognition and measurement criteria and the consolidation criteria and methods used for the consolidated financial situation at September 30, 2025 are the same as those adopted for the consolidated financial statements at December 31, 2024 (please see the related report for more information), with the exception of a number of accounting standards. In addition, as from January 1, 2025 the following amendments of accounting standards have become applicable to the Enel Group.

• "Amendments to IAS 21 - The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability", issued in August 2023, clarify how to determine whether a currency is exchangeable for another and, when it is not, the exchange rate to be used. The amendments establish that a currency is considered exchangeable into another when it is possible to obtain the other currency through a market or exchange mechanism that creates enforceable rights and obligations with a normal administrative delay. The assessment of exchangeability must be made at a measurement date and for a specified purpose.

If, in such circumstances, only an insignificant amount of the other currency can be obtained, then the currency is not exchangeable. In that case, an entity is required to estimate the spot exchange rate reflecting the rate at which an orderly exchange transaction would take place at the measurement date between market participants, under prevailing economic conditions. The amendments do not specify how to estimate the spot exchange rate for a currency that is not exchangeable, allowing the use of an observable exchange rate without adjustment or another estimation technique.

Under the amendments, companies need to provide new disclosures, providing information that enable users to assess how the fact that a currency is not exchangeable into another currency affects, or is expected to affect, their financial performance, financial position and cash flows.

The application of the amendments, as currently stands, has not had a material impact in this consolidated financial situation at September 30, 2025.

2. Argentina – Hyperinflationary economy: impact of the application of IAS 29

As from July 1, 2018, the Argentine economy has been considered hyperinflationary based on the criteria established by "IAS 29 - Financial reporting in hyperinflationary economies". This designation is determined following an assessment of a series of qualitative and quantitative circumstances, including the presence of a cumulative inflation rate of more than 100% over the previous three years.

For the purposes of preparing this consolidated financial situation and in accordance with IAS 29, certain items of the balance sheets of the investees in Argentina have been remeasured by applying the general consumer price index to historical data in order to reflect changes in the purchasing power of the Argentine peso at the reporting date for those companies.

{85}------------------------------------------------

Bearing in mind that the Enel Group acquired control of the Argentine companies on June 25, 2009, the remeasurement of the non-monetary balance sheet figures was conducted by applying the inflation indices starting from that date. In addition to being already reflected in the opening balance sheet, the accounting effects of that remeasurement also include changes during the period. More specifically, the effect of the remeasurement of non-monetary items, the components of equity and the components of the income statement recognized in the nine months of 2025 was recognized in a specific line of the income statement under financial income and expense. The associated tax effect was recognized in taxes for the period.

In order to also take account of the impact of hyperinflation on the exchange rate of the local currency, the income statement balances expressed in the hyperinflationary currency have been translated into the Group's presentation currency (euro) applying, in accordance with IAS 21, the closing exchange rate rather than the average rate for the period in order to adjust these amounts to current values.

The cumulative changes in the general price indices from December 31, 2018 to September 30, 2025, are shown in the following table:

Periods Cumulative change in general consumer price index
From July 1, 2009 to December 31, 2018 346.30%
From January 1, 2019 to December 31, 2019 54.46%
From January 1, 2020 to December 31, 2020 35.41%
From January 1, 2021 to December 31, 2021 49.73%
From January 1, 2022 to December 31, 2022 97.08%
From January 1, 2023 to December 31, 2023 222.01%
From January 1, 2024 to December 31, 2024 109.22%
From January 1, 2025 to September 30, 2025 22%

86

In the nine months of 2025 the application of IAS 29 generated net financial income from hyperinflation adjustments (gross of tax) of €108 million.

The following tables report the effects of IAS 29 on the balance sheet at September 30, 2025 and the impact of hyperinflation on the main income statement items for the nine months of 2025, differentiating between that concerning the revaluation on the basis of the general consumer price index and that due to the application of the closing exchange rate rather than the average exchange rate for the period in accordance with the provisions of IAS 21 for hyperinflationary economies.

3. Main changes in the consolidation scope

At September 30, 2025, the scope of consolidation changed with respect to September 30, 2024 and December 31, 2024, as a result of the following main transactions:

2024

  • On January 4, 2024, the Enel Group, acting through its wholly-owned subsidiary Enel Green Power North America (EGPNA), closed the sale of a renewable asset portfolio in the United States for a total of €253 million. The assets sold include EGPNA's entire geothermal portfolio as well as a number of small solar plants, with a total capacity of about 150 MW of operating plants. The transaction had a positive impact on the Group results of €8 million.

  • On May 10, 2024, Enel Perú SAC, controlled by Enel SpA through Enel Américas SA, finalized the sale to Niagara Energy SAC of all the equity stakes held in the power generation companies Enel Generación Perú SAA and Compañía Energética Veracruz SAC for a total €1,198 million. The sale generated a positive impact of €9 million on Group profit for the period, taking account of the negative effects associated with the release of the associated translation reserves.

  • On June 12, 2024, Enel Perú SAC also finalized the sale to North Lima Power Grid Holding SAC of the

  • entire equity stakes held in Enel Distribución Perú SAA and in advanced energy services company Enel X Perú SAC, for a total €2,880 million. The transaction generated a positive impact on Group profit of €509 million, taking account of the negative effects associated with the release of the associated translation reserves.

  • At the beginning of October 2024 the Enel Group, acting through the subsidiary Enel North America, completed the sale of the assets relating to the storage business in North America to MSS Energy Storage LLC (for assets in the United States) and MSS LP Holdings Inc. (for assets in Canada) for a total of €160 million. The transaction generated a negative impact on Group profit of €44 million.

  • On December 30, 2024 Enel SpA, acting through its subsidiary e-distribuzione SpA, finalized the sale to A2A, of 90% of the share capital of Duereti Srl, a vehicle beneficiary of the contribution of electricity distribution services in a number of municipalities in the provinces of Milan and Brescia for €1,229 million.

In the nine months of 2025 revenue from the "sale of electricity" decreased by €3,174 million compared to the same period of 2024 (-9.6%), to €29,960 million. The decrease was largely accounted for by Italy (€2,192 million), mainly reflecting a decline in volumes sold on the retail market and the update of rates applied in the year, and Peru (€549 million) following the sale of generation and distribution assets.

Revenue from the "transport of electricity" increased by €427 million, mainly reflecting the remuneration of distribution and metering costs in Italy.

"Fees from network operators" posted an increase of €345 million compared to the nine months of 2024, essentially attributable to Italy and reflecting the fees for the capacity market mechanism and system security.

The decrease in revenue from the "sale and transport of gas" of €510 million on the nine months of 2024 is mainly attributable to a decrease in sales volumes on the retail market and to the update of the more favorable contractual conditions applied to end users.

The decrease in gains on sale of subsidiaries (€1,336 million) is mainly attributable to the recognition in the 1st Half of 2024 of gains on the disposal of generation and distribution assets in Peru (€1,347 million).

{90}------------------------------------------------

2. Consolidated financial situation at September 30, 2025 1. Report on Operations

"Electricity purchases" decreased by €791 million compared to the same period of 2024. More specifically, the decrease mainly reflects developments in Italy, mainly reflecting the decrease in volumes connected with the elimination of the enhanced protection market for non-vulnerable clients, as well as the sale of generation and distribution assets in Peru, partly offset by an increase in electricity purchases in Spain reflecting increasing average costs. The item includes the result of the fair value measurement of contracts for the purchase of electricity with physical settlement closed in the nine months of 2025, which increased by €71 million on the corresponding period of 2024.

The decrease in costs for "consumption of fuel for electricity generation" is mainly connected to decreasing electricity generation from fossil sources in Italy compared to the same period of 2024, mainly in Italy and Spain.

The increase in costs for the purchase of "fuel for trading and gas for sale to end users" essentially reflects increasing average prices of gas and developments in volumes handled. The item includes the results of the fair value measurement of gas purchase contracts with physical settlement closed in the nine months of 2025, which posted an increase of €3,101 million compared with the corresponding period of 2024.

Costs for "personnel" amounted to €3,456 million, a decrease of €14 million (-0.4%).

The Enel Group workforce at September 30, 2025 numbered 61,192, of which 29,603 employed outside Italy. In the nine months of 2025, the workforce increased by 833, mainly reflecting the acquisition of Corporación Acciona Hidráulica SL in Spain (+36) and the balance between new hires and terminations (+797).

{92}------------------------------------------------

2. Consolidated financial situation at September 30, 2025 1. Report on Operations

The overall change compared with December 31, 2024 breaks down as follows:

Balance at December 31, 2024 60,359
Hirings 3,206
Terminations (2,409)
Change in consolidation scope 36
Balance at September 30, 2025 61,192

Costs for "services, rentals and leases" in the nine months of 2025 are essentially in line with the same period of 2024 and include wheeling in the amount of €7,060 million (€6,873 million in the corresponding period of 2024), mainly in Italy and Iberia, maintenance and repair services, services connected with the electrical and gas business, IT services and rentals and leases.

The increase in "depreciation, amortization and other impairment losses" in the nine months of 2025 mainly reflects an increase in depreciation and amortization of property, plant and equipment and intangible assets connected with investments made in the renewable energy sector, partly offset by a decrease in impairment losses on trade receivables.

Costs for "environmental certificates" decreased by €197 million mainly reflecting a decline in the prices of guarantees of origin.

"Other costs connected with electrical and gas system" increased by €46 million mainly reflecting the increasing impact of the Bono Social in Spain.

"Other taxes and duties" increased by €92 million essentially reflecting the increase in the tax on the value of electricity generation (IVPEE) recognized in Spain following its progressive reactivation in 2024 by Royal Decree 8/2023.

"Extraordinary solidarity levies" regard the extraordinary solidarity levy recognized in the nine months of 2024 in Spain in the amount of €202 million following the approval of Law 38 of December 27, 2022. The levy is no longer due as from 2025.

"Capital losses and other costs on the disposal of equity investments" in the nine months of 2025 include the impact of the disposal of the residual interest in Slovak Power Holding BV, with the release to profit or loss of the negative OCI reserves in respect of the associate (€341 million).

4.c Net results from commodity contracts – €538 million

Net results from commodity contracts showed net income of €538 million in the nine months of 2025 (net expense of €434 million in the corresponding period of 2024) and break down as follows:

• net income from commodity derivatives totaling €285 million (net expense of €606 million in the nine months of 2024) relating to derivatives designated as cash flow hedges and derivatives measured at fair value through profit or loss. In particular, the net income from derivatives settled in the period amounted to €121 million (net expense of €745 million in the nine months of 2024) and the

  • net fair value gain on outstanding derivatives came to €164 million (net income of €139 million in the nine months of 2024);
  • net fair value gain on energy commodity contracts with physical settlement still outstanding at the reporting date amounting to €253 million (net fair value gain of €172 million in the nine months of 2024).

The increase in net results from commodity contracts came to €972 million, mainly reflecting the results from derivatives entered into to hedge commodity price risk, mainly due to the fluctuation of market prices.

{93}------------------------------------------------

4.d Net financial income/(expense) – €(2,045) million

Net financial expense amounted to €2,045 million, a decrease of €265 million on the same period of 2024, mainly reflecting:

  • a decrease of €413 million in interest expense and other charges on financial debt primarily reflecting
  • the reduction in the average debt in the period;
  • a decrease of €138 million in net income from hyperinflation recognized by the Argentine companies as a result of the application of IAS 29 due to the decrease of the average inflation rate in Argentina.

4.e Share of profit/(loss) of equity-accounted investments – €(41) million

The share of the net loss of equity-accounted investments increased by €35 million compared with the same period of the previous year, mainly attributable to:

  • a number of associates of EGPNA Renewable Energy Partners and Rocky Caney which, following the asset
  • swap agreement between Enel Green Power North America and Gulf Pacific Power, were reclassified under "assets held for sale" with a total impairment loss of €29 million;
  • the decrease in the share of profit/(loss), most notably of Gridspertise.

4.f Income taxes – €2,567 million

Income taxes in the nine months of 2025 came to €2,567 million, a decrease of €836 million on the same period of 2024, equal to 29% of pre-tax profit (32.7% in the nine months of 2024). The decrease in the tax rate essentially reflects the decreasing impact of mergers and acquisitions, which in 2024 mainly regarded the sale of distribution and generation assets in Peru, as well as the non-deductibility of the extraordinary solidarity levy recognized in the nine months of 2024 in Spain.

Information on the condensed consolidated statement of financial position

Assets

5.a Non-current assets – €144,447 million

Property, plant and equipment and intangible assets, including investment property, amounted to €109,486 million at September 30, 2025, a decrease of €965 million.

More specifically, the increases generated by:

  • investments in the period in the amount of €6,176 million;
  • the recognition of property, plant and equipment in the amount of €980 million following the acquisition in Spain of 34 hydro plants from the Acciona Group and wind plants from Caja Rural de Soria and Caja Rural de Navarra;
  • hyperinflation effects in Argentina in the amount of €367 million gross of the impact on depreciation and amortization;
  • new lease contracts (€399 million);
  • the capitalization of interest on loans obtained specifically for investments in property, plant and equipment (€50 million);
  • the net effect of reclassification of assets as held for sale (€25 million) and the reclassification of assets held for sale to non-current assets "held for use" in respect of Enel Generación Piura SA in Peru (€130 million), since the conditions that had determined the previous classification under IFRS 5 no longer apply, partly offset by the reclassification to assets held for sale of a number of companies in North America included in the asset swap transaction relating to renewable plants (€105 million),

were more than offset by depreciation, amortization and impairment losses on these assets (€5,305 million), exchange losses (€3,503 million) and grants received from e-distribuzione (€212 million).

Goodwill came to €13,059 million, an increase of €209 million mainly attributable to the price allocation process following the acquisitions of Corporación Acciona Hidráulica SL and Compañía Eólica Tierras Altas SA (Cetasa) in Spain, for €125 million and €52 million respectively.

Please note that the price allocation for Cetasa is not final, as the company was acquired on July 31, 2025.

Other changes mainly include the reclassification from assets held for sale to continuing operations of Enel Generación Piura SA (€25 million) and positive exchange rate adjustments in Brazil, partly offset by negative exchange rate adjustments in North America, Chile and Central America (€7 million).

Equity-accounted investments amounted to €1,432 million, a decrease of €24 million on December 31, 2024 mainly reflecting:

  • the capital increase (€122 million) in the joint venture Potentia Energy allowing the latter to finalize an agreement with CVC DIF and Cbus Super for acquiring interests in a portfolio of over 1 GW of renewable assets;
  • the classification under "assets classified as held for sale" of a number of assets of EGPNA Renewable Energy Partners and Rocky Caney, in the amount of €58 million following the finalization of an asset swap agreement with Gulf Pacific Power which will allow Enel Green Power North America to increase to 51% its indirect interest in a number of wind plants owners, in exchange for certain investments, one 100%-subsidiary and other associates. Please note that the transaction was finalized on October 1, 2025. For further details, please see the section "Subsequent events";
  • negative impacts of changes in the scope of consolidation in the amount of €34 million, mainly in respect of the disposal of an interest in Energie Electrique de Tahaddart and the acquisition from Caja Rural de Soria and Caja Rural de Navarra of the residual 62.5% investment held by Enel Green Power España SLU in Cetasa (Compañía Eólica Tierras Altas) which led to the full consolidation of the investment and its elimination from associates;
  • the loss pertaining to the Group, in the amount of €19 million;
  • the collection of dividends in the amount of €20 million;
  • adverse exchange rate developments in the amount of €24 million.

Other non-current assets 1,524 1,546 (22) -1.4%
Total 20,470 21,095 (625) -3.0%

(1) The item includes investments of the period in contract assets of €660 million (€844 million at December 31, 2024).

The decrease in the period is primarily attributable to:

  • the decrease in "deferred tax assets" (€656 million), mainly linked to developments in the fair value of cash flow hedge derivatives and the impact of exchange differences mainly in Latin America;
  • the decrease in the fair value of "non-current financial derivative assets", mainly related to cash flow hedge derivatives (€845 million) primarily involving contracts transacted to manage exchange rate risk.

These factors were partially offset by:

  • the increase in "financial assets from service concession arrangements", mainly in Brazil;
  • the increase in "amounts due from institutional mar-

ket operators", in Spain and Italy, relating to distribution activities;

  • the increase in "contract assets", in Brazil, which mainly includes assets being developed in respect of public services under "public-to-private" concession arrangements, expiring beyond 12 months, recognized in accordance with IFRIC 12;
  • the increase in "other non-current financial assets included in net financial debt", reflecting the increase in securities at FVOCI which essentially represent the financial instruments in which Enel Reinsurance invests part of its liquidity.

Finally, the item comprises: long-term financial receivables in the amount of €2,070 million (€2,101 million at December 31, 2024) and securities for €693 million (€575 million at December 31, 2024).

5.b Current assets – €36,656 million

Inventories amounted to €4,016 million, an increase of €373 million.

The change mainly reflects an increase in environmental certificates (€318 million), primarily emission allowances not intended for compliance in Spain, and in inventories of raw materials (€53 million).

Trade receivables amounted to €14,926 million, a decrease of €1,015 million mainly in Italy, Spain and Chile.

2. Consolidated financial situation at September 30, 2025 1. Report on Operations

Other current assets include:

Millions of euro at Sept. 30, 2025 at Dec. 31, 2024 Change
Other current financial assets included in netfinancial debt 4,199 4,668 (469) -10.0%
Current financial assets in respect of jointdevelopment agreements (JDA) - 10 (10) -
Current financial derivative assets 2,712 3,512 (800) -22.8%
Other current financial assets 160 176 (16) -9.1%
Tax assets 2,607 2,059 548 26.6%
Amounts due from institutional marketoperators 1,153 904 249 27.5%
Other current assets 2,172 1,908 264 13.8%
Total 13,003 13,237 (234) -1.8%

The decrease in the period mainly reflects:

  • the reduction in the fair value of "current financial derivative assets", essentially relating to derivatives at FVTPL (€479 million) and cash flow hedge derivatives (€356 million), primarily connected with contracts transacted to manage commodity price risk and currency risk;
  • the decrease in "other current financial assets included in net financial debt" reflecting a decline in the current portion of long-term financial assets (€953 million), partly offset by the increase in short-term financial receivables (€378 million), referring mainly to cash collateral paid to counterparties and time deposits, and in short-term securities (€106 million). This item consists of: short-term financial receivables for €2,734 million (€2,356 million at December

31, 2024), the current portion of long-term financial receivables for €1,221 million (€2,174 million at December 31, 2024) and securities for €244 million (€138 million at December 31, 2024).

These adverse effects were partially offset by:

  • the increase in "income and other tax assets", mainly related to income tax assets, connected with the estimated tax liability for the period (€769 million) partly offset by the decrease in VAT credits;
  • the increase in "amounts due from institutional market operators", in Spain and Italy, relating to distribution activities;
  • the increase in receivables for expired derivatives (€104 million) and prepaid expenses (€126 million) included in "other current assets".

{97}------------------------------------------------

5.c Assets classified as held for sale – €233 million

The item includes assets measured at the lower of cost, understood as their net carrying amount, and their estimated realizable value, which, due to management decisions, meet the requirements of "IFRS 5 - Non-current assets held for sale and discontinued operations" for their classification in this item.

In the nine months of 2025 the item decreased by €182 million compared to December 31, 2024, mainly reflecting:

  • the classification to assets "held for use" of assets in respect of Enel Generación Piura, for €204 million, since the conditions that had determined the previous classification under IFRS 5 no longer applied, and management no longer considered the disposal highly probable;

  • the classification under net assets available for sale of a number of US companies as part of the asset swap agreement with Gulf Pacific Power for €125 million;

  • the partial disposal of land located in Spain, in Palma

  • de Mallorca, for €28 million, already classified as held for sale at December 31, 2024;

  • the disposal of the Colombian company Wind Autogeneración, owner of the Windpeshi wind project, for €49 million, to Ecopetrol.

Note that in the 1st Half of 2025 the sale of Slovak Power Holding BV was finalized following the agreement on December 18, 2024, when the company was reclassified as held for sale and fully written off. For this reason, the transaction did not entail any changes in the balances of assets and liabilities held for sale. For more information on the financial effects of these transactions please see the section "Main changes in the consolidation scope".

  1. Report on Operations

2. Consolidated financial situation at September 30, 2025

Equity and liabilities

5.d Equity attributable to the owners of the Parent – €35,288 million

The increase of €1,557 million in the nine months of 2025 in equity attributable to the owners of the Parent mainly reflects profit for the period (€5,236 million), the change in the reserve for perpetual hybrid bonds due to new issues, net of repayments, in the amount of €1,074 million, the monetary revaluation of €133 million in Argentina owing to the application of the provisions of IAS 29 (financial reporting in hyperinflationary economies) and the net result of transactions on non-controlling interests for €83 million, the latter mainly relating to the buyback transactions by Endesa and Enel Américas. These positive factors were partly offset by dividends paid in the amount €2,830 million (including coupons paid to holders of perpetual hybrid bonds in the amount of €240 million), a decrease in the translation reserve (€1,560 million) following the strengthening of the euro against other currencies and the decrease in reserves related to the buyback transaction launched by Enel SpA (€1,000 million).

5.e Non-current liabilities – €86,364 million

Long-term borrowings amounted to €58,455 million (€60,000 million at December 31, 2024) and consist of: bonds in the amount of €41,242 million (€42,282 million at December 31, 2024), bank borrowings in the amount of €14,485 million (€14,755 million at December 31, 2024) and other borrowings of €2,728 million (€2,963 million at December 31, 2024).

Long-term borrowings decreased by €1,545 million on December 31, 2024 reflecting:

  • a decrease in bonds of €1,040 million, mainly due to the reclassification of the short-term portion (€4,862 million) and positive exchange rate developments (€2,314 million). These effects were partly offset by new issues (for a nominal amount of €6,207 million) primarily by Enel Finance International;
  • a decrease in bank borrowings of €270 million mainly due to the reclassification of the short-term portion (€628 million) and positive exchange rate developments (€332 million), partly offset by new issues (for a nominal amount of €1,043 million);
  • a reduction in other borrowings in the amount of €235 million mainly reflecting the decrease in bor-

rowing in respect of tax partnerships in the United States (€163 million).

Provisions and deferred tax liabilities came to €15,491 million at September 30, 2025 (€16,066 million at December 31, 2024) and include:

  • employee benefit liabilities totaling €1,402 million (€1,614 million at December 31, 2024), a decrease of €212 million, connected to uses of €459 million, mainly reflecting the early payment of a number of liability positions in respect of an Enel Distribuição São Paulo pension fund, partly offset by the update of demographic variables, which prompted provisions of €162 million, mainly in Italy and Brazil, and discounting charges of €77 million, mainly in Brazil;
  • "non-current portion of provisions for risks and charges" of €6,426 million (€6,501 million at December 31, 2024), with no significant changes in the period;
  • "deferred tax liabilities" of €7,663 million (€7,951 million at December 31, 2024), a decrease of €288 million, primarily reflecting cash flow hedge derivatives and the impact of exchange differences in Latin America.

{99}------------------------------------------------

Other non-current liabilities include:

Millions of euro at Sept. 30, 2025 at Dec. 31, 2024 Change
Non-current financial derivative liabilities 3,581 2,915 666 22.8%

Liabilities for tax partnerships 745 1,001 (256) -25.6%
Liabilities with equalization funds/market andenergy services operators 233 297 (64) -21.5%
Other items 1,264 1,164 100 8.6%
Total 12,418 12,089 329 2.7%

The change in the period primarily reflects:

  • the increase in the fair value of "non-current financial derivative liabilities", mainly attributable to derivatives designated in hedge accounting (€650 million) mainly to hedge currency risk;
  • the decrease in "liabilities for tax partnerships" at the North American companies, following the entry into operation of a number of plants;
  • the decrease in "contract liabilities" in Italy, in respect of deferred income from connection fees which is recognized at the time of connection to the network;
  • the increase in "other items", mainly attributable to regulatory liabilities in Brazil.

5.f Current liabilities – €45,115 million

Short-term borrowings and current portion of longterm borrowings amounted to €10,686 million (€11,084 million at December 31, 2024) and include short-term borrowings for €1,967 million (€3,645 million at December 31, 2024) and the current portion of long-term borrowings for €8,719 million (€7,439 million at December 31, 2024).

The item decreased by €398 million on December 31, 2024, reflecting the decrease in short-term borrowing for €1,678 million mainly connected to the reduction in commercial paper (€1,159 million) in Enel Finance International.

This effect was partly offset by the increase in the current portion of long-term borrowings (€1,280 million), mainly regarding the current portion of bonds (€1,524 million) in which the reclassification of the short-term portion was largely offset by redemptions and favorable exchange rate developments.

Trade payables amounted to €10,486 million, down €3,207 million mainly in Italy, Spain and Chile.

{100}------------------------------------------------

2. Consolidated financial situation at September 30, 2025 1. Report on Operations

Other current liabilities break down as follows:

Millions of euro at Sept. 30, 2025 at Dec. 31, 2024 Change
Current derivative liabilities 2,616 3,584 (968) -27.0%
Other current financial liabilities included in netfinancial debt 3 14 (11) -78.6%
Other current financial liabilities 935 831 104 12.5%

Dividends 146 2,523 (2,377) -94.2%
Other current liabilities 4,285 3,557 728 20.5%
Total 23,943 24,886 (943) -3.8%

The change in the period is essentially due to:

  • a decrease in amounts due for "dividends" reflecting dividends paid during the nine months of 2025;
  • a decrease in the fair value of "current derivative liabilities", mainly regarding derivatives at FVTPL (€877 million), mainly entered into to manage commodity price risk;
  • a decrease in "amounts due to institutional market operators", mainly attributable to e-distribuzione primarily for the decrease in amounts due to the Energy and Environmental Service Fund - CSEA, mainly for the reduction in the liabilities for rate components and system charges;
  • a decrease in "amounts due to employees and social security institutions".

These effects were partially offset by:

  • the increase in "tax liabilities", mainly in respect of the estimated income tax liability for the period (€1,155 million) and VAT liabilities (€296 million);
  • the increase in "provisions for risks and charges (current portion)", mainly reflecting an increase in the provision for emission allowances in Spain and Italy;
  • the increase in "other current liabilities", essentially connected to the recognition of the liability for the buyback transaction by Enel SpA and Enel America, and the increase in debts relating to expired derivatives.

{101}------------------------------------------------

The balance of liabilities included in disposal groups classified as held for sale and discontinued operations at September 30, 2025 decreased by €81 million on December 31, 2024 mainly reflecting:

  • the classification of liabilities in respect of Enel Generación Piura under current and non-current liabilities for €106 million since the conditions that had determined the previous classification under IFRS 5 no longer applied, and management no longer considered the disposal highly probable;
  • the classification under liabilities held for sale of a number of companies in North America as part of the swap agreement with Gulf Pacific Power for €56 million;
  • the decrease in the liabilities associated to the partial disposal of land located in Spain for €17 million already classified as held for sale at December 31, 2024.

- sureties and other guarantees granted to third parties 2,836 3,300 (464)
Commitments to suppliers for:
- electricity purchases 57,506 56,438 1,068
- fuel purchases 34,155 44,008 (9,853)
- various supplies 3,227 3,614 (387)
- tenders 5,765 5,608 157

Commitments for the purchase of fuels are determined with reference to the parameters and exchange rates applicable at the end of the period (as prices are variable and mainly denominated in foreign currency). At September 30, 2025 they amounted to €34,155 million, of which €19,880 million refer to the period October 1, 2025-2029, €7,735 million to the period 2030-2034, €5,751 million to the period 2035-2039, and the remaining €789 million beyond 2039.

The increase in commitments for the purchase of electricity essentially reflects rate adjustments and supplies in Latin America.

The decrease in commitments for the purchase of fuels mainly refers to gas in Italy and Spain reflecting the contraction in volumes purchased.

{112}------------------------------------------------

Tax litigation in Brazil

Compared with the consolidated financial statements at December 31, 2024, which the reader is invited to consult for more information, the following main changes have occurred in tax-related contingent assets and liabilities.

ICMS – Coelce

The State of Ceará has filed various tax assessments against Companhia Energética do Ceará SA over the years (for tax periods 2015-2020), as well as against all other energy distributors in Brazil, demanding the ICMS (Imposto sobre Circulação de Mercadorias e Serviços, tax on the circulation of goods and services) on the subsidies paid by the Federal government against the regulatory discounts granted to certain consumers.

The company has appealed the individual assessments, defending its actions at the various levels of jurisdiction.

The amount involved in the dispute at September 30, 2025 is about €109 million.

IRPJ/CSLL tax credits – Enel Brasil, Eletropaulo and Enel Green Power Volta Grande

The Federal Tax Authority served Enel Brasil, Eletropaulo and Enel Green Power Volta Grande a number of tax assessments contesting the offsetting of tax credits relating to IRPJ (Imposto sobre a Renda das Pessoas Jurídicas) and CSLL (Contribuição Social sobre o Lucro Líquido) arising from taxes paid in excess in previous years in monthly advance payments.

2. Consolidated financial situation at September 30, 2025

As regards Enel Brasil, the Federal Tax Authority contests the offsetting of IRPJ and CSLL tax credits in the 2020 tax period since, due to a formal error in completing the certifications for withholdings operated on financial revenue, it considered the calculation on the company's income tax to be incorrect. Enel Brasil filed an appeal against the tax assessment, since it is based on a mere formal error, defending in the various levels of jurisdiction the validity of the offsets claimed.

As regards Enel Green Power Volta Grande, the Tax Authority is contesting the IRPJ and CSLL tax credit offsetting for the 2019 tax period, essentially due to a difference between the statement filed to the Tax Authority and the amounts the company was actually entitled to offset. The company maintains that the right to the tax credit exists and can be demonstrated through the relevant accounting records and further supporting documentation.

As regards Eletropaulo, the assessments relate to tax credits offset in the 2000 and 2002 tax periods, as they concerned unapproved credits, arising from excess advances paid in 1998. Following unfavorable decisions in the first and second administrative instances, the company has filed a request for clarification to the same Court in order to take into consideration the established jurisprudence regarding the possibility of using credits deriving from excess payments of IRPJ or CSLL as compensation, even if not approved or awaiting approval.

The overall amount involved in the disputes at September 30, 2025 is about €107 million.

9. Subsequent events

Enel increases its US consolidated renewable capacity by 285 MW

On October 1, 2025, Enel Green Power North America (EGPNA), a wholly owned subsidiary controlled through Enel North America, closed an asset swap transaction with Gulf Pacific Power. Pursuant to the agreement, EG-PNA increased to 51% its stake in a number of corporate vehicles owning wind farms. At the same time, the company disposed of a number of minority interests in wind farms and its entire stake in a smaller wind facility, for a cash consideration of about $50 million subject to an adjustment mechanism typical for this type of transactions. As a result, Enel increased its net installed consolidated capacity in the United States by 285 MW. The transaction is in line with the Group's strategy to increase its generation capacity from renewable sources, including through the acquisition of assets already in operation (brownfield).

{113}------------------------------------------------

Enel and Masdar finalized the partnership agreement signed in March 2025 for 446 MW of operating photovoltaic plants in Spain

On October 2, 2025 Enel Green Power España, a Group company controlled through Endesa, closed the sale to Masdar, the UAE's clean energy leader, of a non-controlling interest of 49.99% in the share capital of EGPE Solar 2, a vehicle owning four Endesa photovoltaic assets operating in Spain with total installed capacity of 446 MW.

In line with the agreement signed on March 24, 2025, Masdar paid €184 million for the acquisition of 49.99% of the share capital of EGPE Solar 2, subject to adjustments customary for this type of transactions.

The transaction, following the partnership with Masdar finalized in December 2024 on a 2 GW portfolio of other solar assets already operating in Spain, is in line with the aim of retaining control on strategic assets while maximizing productivity and returns on invested capital set in the 2025-2027 Strategic Plan.

Enel presents LENE, the new digital company of the Group

On October 28, 2025, the Group established LENE, a new digital company, focusing on the offer of electricity and subsequently also gas-related services, with the aim of controlling a growing market segment characterized by a preference for digital channels.
