Foreword The Interim Financial Report at March 31, 2026 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 practices in the main financial markets, while also taking due account of the quarterly reporting requirements of a number of major listed subsidiaries. ‌Enel organizational model ENEL GROUP CHAIRMAN P.

Reference scenario The macroeconomic environment The 1st Quarter of 2026 was characterized by a global environment marked by persistent geopolitical uncertainties, as well as risks related to possible energy shocks and tensions in the Middle East, which continue to affect the international growth and inflation outlook. Against this backdrop, monetary and fiscal policies remain geared toward supporting economic resilience, while governments are called upon to mitigate the impact of energy price increases and strengthen energy efficiency. In the United States, GDP growth is expected to be 2.5% year-on-year in the 1st Quarter, accelerating from the previous period (2.0%), despite continued uncertainty related to trade policies and energy price tensions. Inflation stood at 2.4% year-on-year, signaling price dynamics still above the Federal Reserve's target. Domestic demand remains solid, although there are downside risks related to labor market developments and the fiscal policy outlook. Economic recovery remains weak in the euro area, with GDP growth estimated at 0.8% year-on-year in the first three months of the year. Although penalized by adverse temporary factors - including unfavorable weather conditions that affected industrial activity, particularly in Germany - growth continues to be mainly driven by domestic demand, especially private consumption, aided by resilient labor markets. However, elements of fragility remain on the external front, with exports still suffering from unfavorable global conditions related to geopolitical tensions. Inflation rose to 2.5% in March, driven mainly by energy prices, showing a temporary departure from the European Central Bank's (ECB) target. Against this backdrop, the ECB's stance remains uncertain, with the possibility of a wait-and-see approach in the face of upside risks to inflation and downside risks to growth. In Latin America, the economic picture remains heterogeneous. In Brazil, GDP growth is expected at 1.1% year-on-year in the 1st Quarter, reflecting still weak domestic demand and a gradual recovery in the services sector. Inflation stood at 3.8% in March, down from last year's levels (average of 5% in 2025), allowing the central bank to cut the key interest rate by 25 basis points to 14.75% in March. In Chile, economic growth is estimated at 1.0% year-on-year, in a context of still low inflation and restrictive monetary policy. However, consumer prices rose by 2.8% year-on-year in March, mainly as a result of government measures introduced on March 24, which accelerated the pass-through of higher oil prices to domestic fuels, following changes to the fuel price stabilization mechanism. In Colombia, GDP is estimated to grow by 2.7% year-on-year, supported by a recovery in consumption and robust domestic demand. Inflation remained high, at 5.3% in March, partly due to the increase in the legal minimum wage (+23%) since the beginning of the year. These inflationary pressures prompted the central bank to raise the interest rate to 11.25% (+100 basis points) at its meeting at the end of March, following a similar increase in January. In Argentina, the economy shows moderate growth, estimated at 1.9% in the 1st Quarter, slowing down from the strong momentum in 2025. Growth is mainly driven by export-oriented sectors - agriculture, energy and mining - while consumption and investment show signs of weakening. Inflationary pressures remain contained, thanks to the consolidation of stabilization policies and the controlled exchange rate regime of the Argentine peso. ‌Change in consumer price index (CPI) 1st Quarter Change % 2026 2025 Italy 1.33 1.83 -0.50 Spain 2.73 2.67 0.06 Argentina 32.87 69.10 -36.23 Brazil 4.02 5.03 -1.01 Chile 2.67 4.83 -2.16 Colombia 5.31 5.20 0.11 United States 2.40 2.73 -0.33 Canada 1.97 2.27 -0.30 Exchange rates 1st Quarter Change 2026 2025 Euro/US dollar 1.17 1.05 11.4% US dollar/Argentine peso 1,417.80 1,055.14 34.4% US dollar/Brazilian real 5.26 5.85 -10.1% US dollar/Chilean peso 886.60 963.71 -8.0% US dollar/Colombian peso 3,693.91 4,189.05 -11.8% Energy conditions The commodity market In the 1st Quarter of 2026, the energy commodities and metals markets showed a sharp discontinuity between the first two months of the year and March, due to the closure of the Strait of Hormuz and the escalation of the conflict in the Middle East. While in January and February the market environment was still characterized by high volatility but with largely steady energy flows, March marked a historic turning point, with profound impacts on prices, availability and logistics of key commodities. In the first two months of the year, oil and natural gas prices were somewhat affected by rising geopolitical tensions, but flows through the Strait of Hormuz -through which around 20% of the world's oil and LNG supply transits - continued, albeit with some slowdowns and an increasing risk premium. Brent crude remained at high levels, but still below the $100/bbl mark, while the price of European natural gas (TTF) fluctuated between €28 and €31/MWh, supported by robust seasonal demand and winter concerns, but without any sudden supply shocks. Coal also showed rising prices, supported by still solid demand and logistical tensions. Since the beginning of March, the situation has changed radically: the effective closure of the Strait of Hormuz, a direct consequence of the attacks and retaliation between the United States, Israel and Iran, has led to a collapse in shipping transit, with the number of oil and gas carriers dropping from over 90 per day in February to fewer than 10 in March, and with exports of crude oil and refined products almost reduced to zero for the Gulf's main producers. The impact on prices was immediate and violent: Brent exceeded $110/bbl in mid-March, peaking at up to $118, before falling back on signs of a possible ceasefire. European natural gas saw a surge, with TTF rising above €50/MWh and spot prices reaching €65/MWh, while futures for the rest of the year rose above €40/MWh. On the flow side, the closure of the Strait has led to a drastic reduction in oil and LNG exports from the Gulf: crude oil production in Iraq, Qatar, Kuwait, the United Arab Emirates and Saudi Arabia has been cut by at least 8-10 million barrels per day, with rapidly depleting stockpiles and alternative export capacities (pipelines to the Red Sea and Fujairah) insufficient to compensate for the loss. LNG exports from Qatar and the Emirates were suspended, resulting in a weekly loss of around 2 billion cubic meters and immediate impacts on Europe and Asia. The refined products and coal markets were also under severe strain: the closure of numerous refineries in the Gulf, either due to direct damage or stockpile saturation, reduced the global supply of diesel, jet fuel and LPG, with knock-on effects on prices and availability, especially in Europe and Asia. Finally, the price of CO 2 (EU ETS) returned to growth, up +3.8% to €73.7/ton, reflecting the increase in demand for allowances and the positioning of financial operators, in an environment of tighter environmental regulation, albeit penalized by expectations of a revision of the operating mechanism, in order to contain energy prices in Europe. Base metals prices generally increased, driven by expectations of economic recovery and a more accommodative monetary policy stance in Europe and the United States. Copper prices significantly increased, to around $13,000/ ton, supported by tight fundamentals and expectations of rising demand, especially for energy transition. Aluminum prices also showed a strong rise, to average values around $3,200/ton, while nickel, after a period of oversupply, recovered to higher levels than in the 1st Quarter of 2025. Battery metals bucked the trend, with prices remaining penalized by continued oversupply, although showing signs of rebalancing. 1st Quarter Change 2026 2025 Market indicators Average Brent ICE price ($/bbl) 77.7 74.9 3.7% Average CO 2 price (€/ton) 76.1 73.3 3.8% Average coal price ($/ton CIF ARA) (1) 108.2 102.4 5.7% Average gas price (€/MWh) (2) 39.5 47.0 -16.0% Average copper price ($/ton) 12,852 9,346 37.5% Average aluminum price ($/ton) 3,195 2,629 21.5% Average nickel price ($/ton) 17,357 15,569 11.5% API2 index TTF index.

The figures may change during the year. In the first three months of 2026, electricity demand in Italy grew significantly compared with the same period in 2025 (+3.0%), driven by a recovery in industrial activity and weather conditions in line with the seasonal average. Growth was mainly concentrated on weekdays, a sign of a recovery in the manufacturing sector, while the residential sector remained stable. In Spain, electricity demand increased by 1.5% compared with the 1st Quarter of 2025, but weakened in March, reflecting the slowdown in industrial activity and above-average temperatures. The impact of the Middle East crisis was reflected in a contraction of industrial demand, which affected consumption prospects. In Latin America, electricity demand decreased in Argentina (-4.1%) and Brazil (-1.9%), while it grew in Chile (+0.9%) and Colombia (+4.4%). ‌Electricity prices Average baseload price Q1 2026 (€/ MWh) Change in average baseload price Q1 2026 - Q1 2025 Average peakload price Q1 2026 (€/ MWh) Change in average peakload price Q1 2026 - Q1 2025 Italy 130.2 -5.7% 141.1 -4.3% Spain 43.3 -49.7% 37.5 -53.8% In the 1st Quarter of 2026, electricity prices showed a downward trend compared with the previous year, almost exclusively reflecting the sharp declines in the first two months of the year. In Italy, the average baseload price was €130.2/MWh (-5.7% compared with 2025), reaching €132.7/MWh in January and falling to €114.4/ MWh in February, thanks to the combination of stable demand, strong growth in renewables and falling gas prices. The closure of the Strait of Hormuz and the subsequent surge in gas prices reversed the trend in March, bringing the average monthly price to €143.4/MWh, the highest level for more than a year, with daily peaks above €160/MWh. In Spain, the decrease in prices was even more pronounced in the first two months, with an average baseload price of €71.7/MWh in January and €16.4/MWh in February, reflecting the abundance of renewable and hydroelectric generation and subdued demand. Here too, however, March marked a reversal, with the average price rising to €41.8/MWh, although remaining at historically low levels compared to other European markets.

Source: Enel based on data from the Ministry for Economic Development and Snam Rete Gas. In the 1st Quarter of 2026, demand for natural gas in Italy remained substantially stable compared with the previous year, at around 21.6 billion cubic meters (+0.4%). Growth was mainly concentrated in the thermoelectric sector, while civil and industrial consumption remained unchanged. Spain also recorded an increase, mainly reflecting higher electricity generation through gas-fired plants in January and March. Significant events in the 1st Quarter of 2026 Enel places new €2 billion perpetual hybrid bonds On January 7, 2026, Enel SpA launched on the European market new non-convertible, subordinated perpetual hybrid bonds for institutional investors, denominated in euros, for an aggregate amount of €2 billion. The new issue is structured in two series, has no fixed maturity, and is due and payable only in the event of winding up or liquidation of the Company: €1,250 million bond with a fixed annual coupon of 4.125%; €750 million bond with a fixed annual coupon of 4.500%. The securities are listed both on the regulated market of the Irish Stock Exchange (Euronext Dublin) and the MOT of Borsa Italiana. Enel completes the share buyback program serving its 2025 Long-Term Incentive Plan On January 12, 2026, implementing the authorization granted by the Shareholders' Meeting of May 22, 2025 and the resolution subsequently passed by the Compa-ny's Board of Directors, Enel SpA launched a share buyback program, for 3.2 million shares, equal to approximately 0.0315% of Enel's share capital. The program is designed to serve the Long-Term Incentive Plan 2025 for the management of Enel and/or of its subsidiaries pursuant to Article 2359 of the Italian Civil Code (LTI Plan 2025), which was also approved by the Shareholders' Meeting on May 22, 2025. The program ended on February 19, 2026 with a total outlay of €29.3 million. Decree Law 21 of February 20, 2026 ("Energy bills Decree") On February 20, 2026, Decree Law 21 ("Energy bills De-cree") introduced a package of measures to keep energy costs down for households and businesses. The main provisions affecting the energy sector concern: support to end customers: enhancement of the social electricity bonus for 2026 and introduction of a mechanism of voluntary contributions by sellers in favor of households not benefiting from the bonus; system charges and taxation: reduction of the Asos component for some non-domestic users. This is partly financed through the rescheduling of incentives for large photovoltaic plants under the Conto Energia (Energy Account), the realignment of the timing of system charges payment, and a temporary (2026-2027) 2% increase in the IRAP for companies in the energy sector; wholesale markets and generation: introduction of mechanisms to reduce the wholesale price of electricity and gas, including targeted refunds for thermal generation (subject to European authorization), the optimization of the sale of stored gas and the introduction of a cap on the number of hours of minimum guaranteed prices for bioenergy; infrastructure and grids: new provisions to mitigate vir- tual saturation of the transmission grid, with procedural simplifications and new capacity allocation rules to foster the integration of renewables. The parliamentary process for conversion into law was concluded on April 8, 2026 with final approval by the Senate. The Regulatory Authority for Energy, Networks and the Environment (ARERA) is charged to define the relevant implementation rules for the areas under its jurisdiction. Agreements for the acquisition of an 830 MW portfolio of wind and solar power plants in the United States On February 21, 2026, Enel SpA, acting through its wholly-owned subsidiaries Enel Green Power North America and EGPNA Project HoldCo 2, signed agreements with Excelsior Energy Capital to acquire a portfolio of wind and solar power plants, located in the United States, with a total installed capacity of 830 MW and an expected average annual generation of about 2.1 TWh, for approximately $1 billion (equal to about €850 million) subject to customary adjustments for these types of transactions. The enterprise value on a 100% basis of the portfolio is equal to ‌around $1.3 billion. The transaction is expected to close in the third quarter of 2026. Enel completes a new buyback program of up to €1 billion On February 22, 2026, the Board of Directors of Enel SpA approved the launch of a new share buyback program aimed at providing shareholders an additional remuneration with respect to the distribution of dividends as a result of the cancellation of the treasury shares purchased for this purpose. The program ended on March 30, 2026 with the purchase of 106,661,417 treasury shares, equal to 1.0491% of the share capital), at a volume-weighted average price of €9.3755 per share and a total outlay of approximately €1 billion. Group financing operations On February 22, 2026, the Board of Directors of Enel SpA authorized the issuance of bonds and the subscription and/or renewal of bank loans by Enel and/or Enel Finance International NV and/or Enel Finance America LLC (in the latter two cases, with a guarantee issued by Enel), for a maximum total amount of €12 billion. Exercise of purchase option on 10% interest in Duereti Srl On March 19, 2026, A2A SpA exercised a purchase option on a 10% interest in Duereti Srl held by e-distribuzione SpA, consistent with the agreement signed between e-dis-tribuzione SpA and A2A SpA on December 30, 2024 The transaction was finalized on April 13, 2026 for €144 million.

It includes 3,680 MW relating to the Brindisi and Torrevaldaliga Nord coal-fired plants in Italy for which the authorization to use coal (AIA requirement) expired on January 1, 2026. At December 31, 2025. It is calculated as the capacity operated under the Stewardship model. Net energy generated by Enel in the 1st Quarter of 2026 increased by 1.13 TWh compared with 2025 (+2.4%), the result of higher thermal generation (+1.35 TWh) reflecting an increase in quantities generated by combined-cycle plants (+1.74 TWh) mainly in Italy and Spain, partially offset by lower generation from coal (-0.36 TWh), fuel oil and turbogas (-0.03 TWh). The increase in energy generation from renewable sources (+0.09 TWh) is mainly attributable to higher generation from wind (+0.49 TWh) mainly in the United States and Spain, and solar (+0.40 TWh) in Chile, Spain and Colombia, partially offset by the decrease in generation from hydroelectric (-0.77 TWh) and other sources (-0.03 TWh).

In particular, revenue from the sale of commodities with physical settlement, including the results from the fair value measurement of transactions closed in the period, sales of gas and other fuels, decreased by €1,269 million overall in Italy compared with the 1st Quarter of 2025, due to the overall decrease in volumes used in trading operations together with a drop of about 14% in the average wholesale price of gas (PSV - Virtual Trading Point). Revenue from the sale of electricity decreased by €558 million, of which €371 million related to Italy, reflecting the decrease in volumes sold (-2.2 TWh) and in average rate applied to customers. These negative effects were partially offset by higher revenue from the transport of electricity and gas (€352 million) mainly related to Spain, Brazil and Italy.

The decrease was fair most pronounced in Italy, where gas procurement costs post a decrease of €1,362 mil- lion compared with the 1st Quarter of 2025, also including fair value measurements at the settlement date of closed transactions, while the costs of electricity purchases decreased by €502 million, due to the decrease in volumes, from 16.1 TWh in 2025 to 12.4 TWh in 2026. Net results from commodity contracts Net results from commodity contracts came to a net expense of €20 million in the 1st Quarter of 2026, down €294 million from net income of €274 million in the same period of 2025. The decrease mainly reflects the increase in prices in the quarter compared with the end Ordinary EBITDA of 2025, negatively impacting the fair value measurement of the exposure of the derivatives portfolio, particularly when compared with the 1st Quarter of 2025, which benefited a particularly positive fair value measurement effects. 1st Quarter Change Millions of euro 2026 2025 (1) Thermal Generation and Trading 698 790 (92) -11.6% Enel Green Power 1,595 1,712 (117) -6.8% Enel Grids 2,539 2,153 386 17.9% Enel Commercial 1,177 1,169 8 0.7% Holding and Services (6) (27) 21 77.8% Total 6,003 5,797 206 3.6% The figures for 2025 do not include the positive impact of the fair value measurement of the commodity portfolio in the 1st Quarter, due to a particularly favorable market scenario. ‌Ordinary EBITDA for the 1st Quarter of 2026 increased by €206 million compared with the same period of 2025, also taking into account the negative effects of exchange rate developments (amounting to €121 million, mainly related to Brazil for €41 million and Argentina for €33 million). EBITDA increased by €386 million in Enel Grids, of which €212 million reflecting an increase in revenue in Spain mainly related to the recognition of regulatory adjustments due to the revision of a number of remuneration parameters following a ruling by the Supreme Court, €71 million EBITDA reflecting an increase in the Regulated Asset Base (RAB) in Italy related to the higher investments made in previous years, and €51 million reflecting the increase in volumes in Brazil combined with the recovery of inflation in the rates. This increase was only partially offset by the decrease in ordinary EBITDA attributable to the Integrated Businesses (€201 million), connected with the results of Thermal Generation and Trading, Enel Green Power and Enel Commercial mainly in Italy, and the lower margins of renewable generation in Latin America, mainly in Chile and Brazil. 1st Quarter 2026 Millions of euro Thermal Generation and Trading Enel Green Power Enel Grids Enel Commercial Holding and Services Total Ordinary EBITDA 698 1,595 2,539 1,177 (6) 6,003 Colombia wealth tax - (9) (7) - - (16) Loss on the Torrevaldaliga Nord and Brindisi coal-fired plants (22) - - - - (22) Loss on 3SUN - - - - (23) (23) EBITDA 676 1,586 2,532 1,177 (29) 5,942 EBITDA came to €5,942 million, down €32 million from the 1st Quarter of 2025, reflecting the factors commented on in the ordinary EBITDA as well as the contribution from non-recurring items, totaling €61 million, mainly related to the losses associated with the Brindisi and Torrevaldaliga Nord (Civitavecchia) coal-fired power plants and the photovoltaic panel production activities in Sicily (3SUN). In particular, in order to provide a better representation of the operating performance of its core business, the results attributable to the two coal-fired power plants mentioned above, together with those attributable to the subsidiary 3SUN, have been excluded from ordinary profit. This new approach is based on the following considerations, which, in the opinion of management, exclude the results of these assets from ordinary operations. Termination of commercial coal operations : the Group is currently awaiting feedback from the MASE on its application to permanently cease operations of the plants. Moreover, as stipulated in the integrated environmental authorizations (AIAs) and in line with the National Integrated Plan for Energy and Climate (PNIEC), the deadline for the use of coal in the two power plants expired on December 31, 2025 and, consequently, they cannot be operated. During this transitional phase, however, the Group continues to incur in a number of operating and safety charges to ensure the use of the plants in case of need. In this context, since these charges are incurred outside the normal production cycle and the use of the power plants would only occur in extraordinary cases, they are no longer attributable to the ordinary business of power generation. Strategic focus and industrial discontinuity : the Group reaffirmed its strategic focus on its primary activities of renewable generation, grid management and customer solutions. In this context, the industrial activity of photovoltaic module production, performed by the subsidiary 3SUN, is characterized by competitive industrial dynamics and risk profiles structurally different from the ordinary business model of the Group. Nevertheless, the Enel Group confirms its commitment to ensure compliance with its commitments to the European Union.

The 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. Group profit came to €1,861 million in the 1st Quarter of 2026, a decrease of €146 million from €2,007 million in the same period of 2025. The decrease is substantially due to higher depreciation and amortization related to capital expenditure made in previous years, while EBITDA was in line with 2025, and reflects the factors commented in the note to the table.

At March 31, 2026 the debt/equity ratio was 1.15 (1.22 at December 31, 2025). The increase in net capital employed of €4,242 million mainly reflected: an increase in net non-current assets mainly related to: property, plant and equipment and intangible assets, which increased mainly as a result of higher investments (€2,053 million), favorable exchange rate developments (€1,275 million) and the acquisition of En- ergía Colectiva (€117 million), offset by depreciation and amortization for the period of €1,762 million; net non-current liabilities, which decreased mainly as a result of the increase in non-current derivative assets (€434 million), non-current financial assets in respect of service concession arrangements (€587 million), receivables due from institutional market operators and for energy services (€83 million), contract assets (€66 million) and tax receivables (€59 million), partially offset by the reclassification to assets held for sale of the investment held in Duereti Srl amounting to €137 million, following the exercise of the purchase option by A2A SpA; ‌the increase in net working capital mainly due to the increase in inventories of CO 2 emission allowances held for trading, as well as the decrease in other net current liabilities, which decreased mainly as a result of the payment of the 2025 interim dividend (€2,369 million), only partially offset by the increase in net tax liabilities (€1,410 million), the negative performance of current derivatives (€461 million) and the increase in amounts due to customers (€149 million). Total equity at March 31, 2026 increased by €3,594 million mainly reflecting the profit for the period (€2,265 million), the net increase in perpetual hybrid bonds (€1,972 million) and the positive contribution of comprehensive income recognized directly in equity (€746 million).

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, considering that the results are measured and evaluated first and foremost for each business line and only thereafter are they broken down by geographical area. Following a new organizational arrangement, management 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 2025 have been restated for comparative purposes.
