resolution no. 15519 of

July, 27 2006

In the year in question A2A S.p.A. shows revenues for a total of 9,270.1 million euro (8,752.8 million euro in the previous year). Sales revenues (8,942.5 million euro) mainly refer to electricity sales to wholesalers, institutional operators, even on IPEX markets (Italian Power Exchange) and subsidiaries, sales of gas and fuels to third parties and subsidiaries and the sale of materials and environmental certificates. Revenues from services (284.3 thousand euro) mainly relate to provisions to subsidiaries of administrative, fiscal, legal, managerial and technical services, and revenues from the Municipality of Milan for the video surveillance service.

The increase in sales revenues is mainly due to the increase in prices on the wholesale markets of both electricity and gas, as well as higher revenues from sales of CO2 mainly due to the higher functioning of the thermoelectric plants managed by A2A S.p.A. through tolling contracts.

Other income (43.3 million euro) have decreased compared to the previous year mainly due to both the lower revenues related to the feed-in tariff incentive mechanism and the lower consideration granted by EP Produzione as the assignee for dispatching of the Scandale plant for the year 2025.

Operating expenses amounted to 8,673.5 million euro (7,880.8 million euro at December 31, 2024) and refer to costs for raw materials (7,658.1 million euro) related primarily to purchases of energy and fuels, both for electricity production and for resale to customers and wholesalers, as well as purchases of materials and environmental certificates; service costs (472.6 million euro), which refer to the logistics costs for the transport on the national network of natural gas, costs for maintenance and repairs related to both the plants and the information systems of the company, as well as costs for services from third parties and from subsidiaries and associates; to other operating costs (542.8

million euro), which refer to the contracting of the thermoelectric production plants tolling agreement of subsidiaries, the costs relating to the use of a portion of the electricity capacity of Ergosud S.p.A., as well as water derivation fees, damages and penalties.

The increase in operating costs derives mainly from the increase in raw material costs, attributable both to the increase in unit procurement prices, due to the increase recorded in the reference scenario, and to the higher volumes purchased, to the higher purchases of environmental certificates, the increase in which is affected both by the higher purchases of CO2 due to the higher volumes emitted related to the higher thermoelectric production and the higher unit procurement cost, by

the increase in costs for the transport and storage of natural gas, partly offset by the decrease in maintenance costs and costs for the provision of IT services, communication and sponsorship.

Personnel expenses amounted to 211.6 million euro (206.3 million euro at December 31, 2024). The increase for the year includes both the effect of contractual renewals and the effect of the increase in staff.

Due to the dynamics mentioned above the Gross operating profit - EBITDA amounted to 385.0 million euro (665.7 million euro at December 31, 2024).

"Amortization and depreciation, provisions and impairment losses" of the year amounted to 205.5 million euro (193.1 million euro at December 31, 2024) and include amortization, depreciation and impairment losses on non-current assets for 177.5 million euro (164.3 million euro at December 31, 2024) and provisions for 28.0 million euro (28.8 million euro at December 31, 2024), mainly related to provisions for risks.

A2A

Separate financial statements 2025

"Operating profit - Ebit" was positive for 179.5 million euro (472.6 million euro at December 31, 2024).

Net finance income and expenses reported a positive balance of 517.4 million euro (positive for 479.5 million euro at December 31, 2024). This item includes dividends from investees companies of 535.0 million euro (395.7 million euro at December 31, 2024), as well as net financial expense of 17.6 million euro (net financial income 83.8 million euro at December 31, 2024).

The "Profit before taxes" was positive for 696.9 million euro (positive for 952.1 million euro at December 31, 2024).

"Income taxes" amounted to 52.7 million euro (163.7 million euro at December 31, 2024) and refer to current taxes calculated on taxable income IRES and IRAP, partially offset by deferred tax assets and liabilities.

The "Profit of the year" was positive for 644.2 million euro (788.4 million euro at December 31, 2024).

***

Net year capex amounted to 606.8 million euro and included net investments in shareholdings, treasury shares, as well as interventions on hydroelectric plants, computer equipment and network devices, buildings, fixed assets in progress, and capex in the Group's information systems and software.

General information on A2A S.p.A.

A2A S.p.A. is a company incorporated under the laws of the Italian Republic which operates, also through its subsidiaries ("Group"), both in Italy and abroad.

In particular, as the "Parent Company", A2A S.p.A. is responsible for the guiding strategy, administration, planning and control, financial management and coordinating the activities of the A2A Group.

Therefore, Group companies benefit from administrative, tax, legal, personnel management, procurement and communication services, so as to optimize the resources that are available within the Group and to use the existing known how in a cost-effective way.

A2A S.p.A mainly operates in the following sectors:

  • production and sale of electricity from hydroelectric plants located in Lombardy, Calabria and Friuli-Venezia Giulia, as well as management of the Group's portfolio of generation plants;

  • trading of electricity, gas and CO₂ through bilateral contracts or on the markets;

  • provision of administrative, tax, legal, treasury, human resources management, procurement and communication services, in order to optimise the resources available within the Group and to efficiently leverage existing know-how in a cost-effective manner.

    The Separate Financial Statements of A2A S.p.A. (hereinafter "the Financial Statements") at December 31, 2025 have been prepared:

  • in compliance with Legislative Decree 58/1998 (art. 154-ter) as amended and with the Issuers' Regulations published by Consob;

  • in accordance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standard Board (IASB) and approved by the European Union. IFRS means all the revised International Accounting Standards (IAS) and all the interpretations of the International Financial Reporting Interpretations Committee (IFRIC), formerly known as the Standing Interpretations Committee (SIC).

In preparing the Financial Statements, the same standards used at December 31, 2024 were applied, other than the principles and interpretations described in detail in the paragraph below "Changes in International Financial Reporting Standards" adopted for the first time on January 1, 2025.

The directors assessed the applicability of the going concern assumption in the preparation of the Financial Statements, concluding that this assumption is appropriate as it was verified that there were no financial, managerial or other indicators that could indicate critical issues regarding the Company's ability to meet its obligations in the foreseeable future and in particular in the next 12 months.

Board of Auditors

and net debt

resolution no. 15519 of

July, 27 2006

The Financial Statements have been prepared using the historical cost method, with the exception of the financial statement items that according to IFRS are recognized at fair value, as indicated in the valuation criteria of the individual items, and non-current assets and disposal groups classified as held for sale that are measured at the lower of carrying amount and fair value net of selling costs.

The Financial Statements required the use of estimates by management; the areas characterized by valuations and assumptions of particular significance, together with those with significant effects on the reported situations, are reported in the section "Use of estimates and judgement by management" at the end of this paragraph.

The currency used for the presentation of the Financial Statements is the euro, the functional currency of the company; all values are expressed in thousands of euro, unless otherwise indicated.

The Financial Statements consist of:

  • Statement of financial position: provides for the distinction of assets and liabilities by maturity, separating between current and non-current;

  • Income statement: presented in scalar form with the individual items analysed by nature. The form chosen, in accordance with the presentation methods of the major sector operators and in line with international practice, is considered the most suitable to represent the company results;

  • Statement of components of the comprehensive income statement: presented in a separate table, it shows the components of the result suspended in equity;

  • Statement of cash flows: prepared using the indirect method, with separate presentation of cash flow from operating activities, investment activities and financing activities.

    More specifically, the Statement of cash flows is presented on a gross basis and does not include non-monetary transactions.

    In particular, although the company does not deviate from the provisions of IAS 7 in the classification of items, the following is specified:

    • in addition to cash flows from ordinary operations, cash flows from operating activities include interest on loans granted and obtained, dividends and advances on dividends paid, as well as dividends received from associated companies or joint ventures;

    • investment activities include investments in property, plant and equipment and intangible assets (including any capitalized financial expenses) and related disposals; investments and disposals in assets deriving from contracts with customers relating to agreements for concession services and other minor investments;

    • cash flows from financing activities include cash flows arising from liability management and lease transactions;

  • Statement of changes in equity: in addition to the components of the comprehensive income statement, it also shows the transactions with shareholders;

  • Explanatory notes.

Separate financial statements 2025

In section 1.b Financial Statements pursuant to Consob resolution no. 15519 of July, 27 2006 are reported Statement of financial position, Income statement and Statement of Cash flow with the effects of relations with related parties, witch are defined in the paragraph 2.7 "Note on related party transaction".

The financial statements presented herein are the same as those used to prepare the Financial Statements at December 31, 2024, with the exception of the following changes that management has adopted to ensure better representation and comparability.

With regard to the statement of financial position, the following steps were taken:

  • disaggregate the financial statement line relating to "Intangible assets and goodwill" through two new lines, respectively "Intangible assets" and "Goodwill";

  • separate current/non-current asset/liability derivatives from the respective other current/non-current assets/liabilities;

  • separate the disbursement expected within the following 12 months from the "Provisions for risks and charges", classifying it as a current liability.

    With regard to the Income Statement, the following steps were taken:

  • separate the item "depreciation, amortization, provisions and impairment losses" by nature: "Amortization, depreciation and impairment losses of non-current assets", "Provision for risks on Impairment losses on trade receivables", "Other provisions for risks";

    As regards the Statement of cash flows, the following steps were taken:

  • saparate the line "net interest paid" into "interest received" and "interest paid";

  • include the information relating to related parties.

The Company also renamed certain lines in the financial statements with respect to the statements published as at December 31, 2024, reclassified inventories of environmental securities relating to the industrial portfolio from "Intangible assets" to "Inventories", and reclassified the portion within the financial year "Provisions for risks and charges". The changes relating to the values at December 31, 2024 are not considered relevant for the economic and equity size of the Company.

In this file, use has been made of some Alternative Performance Indicators that are different from the financial indicators expressly provided for by the IFRS international accounting standards adopted by the Company; for details of these indicators, please see the specific paragraph Alternative Performance Indicators in the Report on Operations.

Changes in International Financial Reporting Standards

Accounting standards, amendments and interpretations applicable by the company as of January 1, 2025

Effective from January 1, 2025, the amendments to IAS 21 "The Effects of Changes in Foreign Exchange Rates," issued by the IASB on August 15, 2023, came into force to regulate the procedures to be followed in the event of a lack of exchangeability between currencies. The amendment introduces requirements to determine when a currency is convertible into another currency and when it is not and requires an entity to estimate the spot exchange rate when it determines that a currency is not convertible into another currency. The amendment had no impact on the financial statements as at December 31, 2025.

Accounting standards, amendments and interpretations endorsed by the European Union but not yet mandatorily applicable and not early adopted by the Company
  1. Amendments to the classification and measurement of financial instruments (Amendments to IFRS 9 and IFRS 7)

    On May 27, 2025, the amendments to IFRS 9 and IFRS 7 regarding "Amendments to the Classification and Measurement of Financial Instruments," issued in 2024, were endorsed, with entry into force scheduled for January 1, 2026.

    These amendments clarify the classification of financial assets with environmental, social and governance (ESG) features and similar ones, as well as the settlement of financial liabilities through electronic payment systems. They also introduce disclosure requirements aimed at enhancing transparency for investors in relation to investments in equity instruments measurement at fair value through other comprehensive income statement and in financial instruments with contingent features, such as features linked to ESG goals.

    • The amendments to IFRS 9 clarify the circumstances under which a financial asset or liability is recognised and derecognised. According to the amendments, a company generally derecognizes its financial liability on the settlement date. Normally, this is the date when the payment is completed. The amendments also introduce an exception, permitting the company to derecognize its financial liability prior to the settlement date, which is the date when the payment is initiated and cannot be cancelled. The exception is available when the company uses an electronic payment system that satisfies all of the following criteria:

      • no practical way to withdraw, stop, or cancel the payment instruction;

      • no practical means to access the money needed for the settlement as a result of the payment instruction;

      • the settlement risk connected with the electronic payment system is insignificant.

        A2A

        Separate financial statements 2025

        • The amendments also provide more precise criteria for determining when a financial asset can be classified as "measured at amortized cost" or "at fair value." This helps companies to treat complex instruments consistently, such as loans with prepayment options or variable clauses (e.g. instruments linked to ESG indices or non-standard variable rates).

          The amendments further clarify how to measure such instruments, with the aim of ensuring that the measurement better reflects the actual economic risk.

        • The amendment to IFRS 7 provides for an additional disclosure for financial assets and liabilities with contractual terms referencing a potential event, including those associated with ESG factors, as well as for equity instruments classified at fair value through other comprehensive income statement elements.

        The Company is currently assessing the impacts of these amendments, but no significant effects are expected.

  2. Nature-dependent electricity contracts (Amendments to IFRS 9 and IFRS 7)

    On June 30, 2025, the amendments to IFRS 9 and IFRS 7 regarding nature-dependent electricity purchase contracts (power purchase agreements) were endorsed. These amendments will enter into force on January 1, 2026.

    The amendments clarify the requirements for applying the "own-use exemption," define the rules for using these agreements as hedging instruments in a hedge accounting relationship, and introduce disclosure obligations to enable investors to understand the effects of such agreements on the company financial performance and future cash flows.

    The Company is currently assessing the impacts of these amendments, but no significant effects are expected.

  3. Annual Improvements to IFRS Accounting Standards-Volume 11

    On July 9, 2025, the annual improvements "Annual Improvements to IFRS Accounting Standards - Volume 11" were endorsed as part of the ordinary improvement process, with entry into force scheduled for January 1, 2026. The annual improvements aim to streamline and clarify existing standards by resolving any inconsistencies identified in the IFRS Accounting Standards or by providing terminological clarifications.

  4. IFRS 18 Presentation and disclosure in financial statements

On February 13, 2026, IFRS 18, issued by the IASB in April 2024, was endorsed, replacing IAS 1 'Presentation of Financial Statements. IFRS 18 introduces new requirements for the presentation of the income statement, including specific totals and subtotals. In addition, entities will have to classify all costs and revenues within the income statement into five categories: operating, investing, financing, income taxes and discontinued operations, where the first three categories are new.

The standard also requires disclosure on the basis of the new definition of management-defined performance measures (MPM), subtotals of costs and revenues, and includes new provisions for the aggregation and disaggregation of financial information on the basis of the identified roles of the "primary" financial statements (PFS) and the notes.

In addition, amendments have been made to IAS 7 Cash Flow Statement, which include the change in the starting point for determining operating cash flows on the basis of the indirect method; from profit or loss to operating profit or loss and the removal of the option to classify cash flows from dividends and interest. In addition, consequential changes were made to several other accounting standards.

IFRS 18, and the amendments to the other standards, are effective for financial years beginning on or after January 1, 2027. However, early application is permitted unless disclosed. IFRS 18 will apply retrospectively.

The Group is currently working, also with the support of external professionals, to identify the impacts that the changes will have on its financial statements and notes to the financial statements, on information systems and on agreements and contracts (e.g. employee benefits and financing contracts/covenants).

2.3

Basis of preparation

Translation of foreign currency items

Items denominated in currencies other than the functional currency, whether monetary (cash and cash equivalents, assets and liabilities that will be collected or paid in fixed or determinable amounts of money, etc.) or non-monetary (advances to suppliers of goods and/or services, goodwill, intangible assets, etc.), are initially recognized at the exchange rate in effect on the date the transaction is

executed. Subsequently, monetary items are converted into the functional currency on the basis of the exchange rate on the reporting date, and differences arising from the conversion are recorded in the income statement. Non-monetary items are maintained at the conversion rate of the transaction.

Property, plant and equipment

Assets for business use are recorded under "Property, plant and equipment" while non-business assets are classified as "Investment properties" if necessary.

Property, plant and equipment are measured at cost, including any additional charges directly attributable to bringing the asset into an operating condition (e.g. transport, customs duty, installation and testing costs, notary and land registry fees and any non-deductible VAT), increased when material and where there are obligations by the present value of the estimated cost of restoring the location from an environmental point of view or dismantling the asset. Borrowing costs, where directly attributable to the purchase or construction of an asset, are capitalized as part of the cost of the asset if the type of asset so warrants.

If important components of tangible assets have different useful lives, they are accounted for separately using the "component approach", assigning to each component its own useful life for the purpose of calculating depreciation (the component approach).

Land, whether occupied by residential or industrial buildings or devoid of construction, is not depreciated as it has an unlimited useful life, except for land used in production activities that is subject to deterioration over time (e.g. quarries).

Ordinary maintenance costs are fully expensed to the income statement in the year they are incurred. Costs for maintenance carried out at regular intervals are attributed to the assets to which they refer and are depreciated over the specific residual possibility of use of such.

Property, plant and equipment are stated net of accumulated depreciation and any impairment losses. Depreciation is charged from the year in which the individual asset enters service on a straight-line basis over the estimated useful life of the asset for the business. The estimated realizable value which is deemed to be recoverable at the end of an asset's useful life is not depreciated. The useful life of each asset is reviewed annually and any changes, if needed, are made with a view to showing the correct value of the asset.

Depreciation of property, plant, and equipment was calculated based on economic and technical useful lives, considered representative of their residual useful life.
