1Q 2026 Press release

• Capex 315 million euro, up 4% compared to the first quarter of the previous year, of which approximately 70% related to development projects for the strengthening and efficiency of electricity distribution networks, for the further construction of photovoltaic assets, as well as for the growth of businesses in the Circular Economy area. 66% of capex is eligible for purposes of the European Taxonomy.
• Adjusted Revenues of 4,552 million euro: +15% compared to the first three months of 2025 (3,968 million euro) thanks to the increase in volumes of electricity sold on retail markets and intermediated on wholesale markets, partly offset by the decline in commodity prices.
• Adjusted EBITDA of 647 million euro, -4% compared to the first quarter of the previous year (675 million euro), mainly due to the decrease in commodity prices, the increase in concession fees and the lower contribution of some treatment plants due to scheduled maintenance and revised service terms on the Acerra contract. This trend was partly offset by the growth of electricity distribution activities, and by higher renewable production.
• Adjusted Net Profit of 221 million euro, down 11% compared to the same period of 2025 (249 million euro), following the contraction in Adjusted EBITDA and the increase in depreciation and amortization due to higher deployment of capex.
• Net Financial Position at 5,628 million euro (5,474 million euro at 31 December 2025), due to seasonal factors. NFP/Adjusted EBITDA ratio of 2.5x (2.4x at 31 December 2025).
• 2.7 GW of RES installed capacity, up 4% compared to the same period in 2025, thanks to the entry into service of new wind and photovoltaic plants.
• 8.1 TWh of electricity sold on retail markets, up 24% compared to the first quarter of 2025, driven by B2B segment, of which 2.7 TWh green electricity sold, up 17% compared to the first quarter of 2025.

• A 200 million euro loan has been signed with the European Investment Bank (EIB), intended for the modernization of the electricity distribution networks in Lombardy, with the renewal of approximately 450 km of medium voltage and 140 km low voltage grids, in line with decarbonisation targets. The share of sustainable debt on total gross debt as of March 31, 2026 was 82% (82% in 2025).

  Milan, 14 May 2026 - The Board of Directors of A2A S.p.A. met today and, under the chairmanship of Roberto Tasca, examined and approved the Quarterly Report as at 31 March 2026.

  "In the first quarter, we confirmed our commitment to the ecological transition, with a capex of 315 million euro, up 4% compared to the same period in 2025. Installed renewable capacity reached 2.7 GW, thanks to the entry into service of new wind and photovoltaic plants, and green production increased by 14%, consolidating A2A's role in promoting the growth of the country's energy autonomy." - comments Renato Mazzoncini, CEO of A2A - "We believe that renewable sources constitute a crucial lever to strengthen national energy independence and stabilize prices for families and businesses, and we hope for an evolution of the regulatory framework that accelerates their development. In a still volatile scenario, the solidity of our economic and financial indicators attests to the effectiveness of the company's industrial model and allows us to look ahead with confidence, continuing with discipline in the implementation of the Strategic Plan and in the generation of sustainable value for all stakeholders."

  Adjusted EBITDA, amounting to 647 million euro, decreased by 4% in the first quarter of 2026 compared to the same period of 2025, mainly attributable to the reduction in margins in the Generation and Trading Business Unit due to higher concession fees and lower energy commodity prices, as well as to lower operating margins of some Group's treatment plants.

  These trends were partially offset by higher production in the renewables portfolio, growth in the electricity distribution business, as well as stable results in the energy retail segment.

  Adjusted Net Profit, amounting to 221 million euro, decreased by 11% compared to the same period of the previous year. This decrease is attributable by two main factors: the contraction in Adjusted EBITDA and the increase in depreciation and amortization following higher capex deployed.

  Net Financial Position, amounting to 5,628 million euro, increasing compared to 31 December 2025, with a leverage ratio of 2.5x which guarantees its full sustainability.

  Guidance

  The outlook for the 2026 financial year confirms an Adjusted EBITDA of between 2.21 and 2.25 billion euro and an Adjusted Group Net Profit of between 0.63-0.66 billion euro.

  Q1 2026 Performance Commentary Adjusted Revenue

  In the first quarter of 2026, the Group's Adjusted Revenue amounted to 4,552 million euro, up 15% compared to the previous year (3,968 million euro). The change is mainly attributable to the increase in the volumes of electricity and gas intermediated in the wholesale markets, the growth in volumes in the retail electricity markets, partly offset by the decrease in energy prices and the contraction in the volumes sold on the retail gas markets.

  Operating costs and personnel costs

  Operating costs amounted to 3,665 million euro, up 20% compared to the first quarter of 2025, due to higher costs related to the increase in commodity volumes, partly offset by the decline in energy prices.

  Personnel costs, amounting to 240 million euro, increased by 4% compared to the same period of the previous year, about 10 million euro. The increase is attributable, on one hand, to the increase in the number of FTEs (Full-Time Equivalents) linked to the hires made during 2025 for the launch of new tenders in the Collection segment and for the upgrading of plants (+162 FTEs, +1.1%, net of the sale of the gas branch to Ascopiave); on the other hand, the effects of salary increases related to contract renewals and merit increases, as well as the higher costs incurred for the share ownership plan aimed at all Group employees.

  Adjusted EBITDA

  Circular Economy	190	202	(12)	-6%
  Smart Infrastructures	129	122	7	6%
  Corporate	-10	-6	(4)	n.s.

  Adjusted EBITDA amounted to 647 million euro, a decrease of 4%, -28 million euro compared to 31 March 2025 (675 million euro), mainly due to the lower contribution of the Circular Economy and Generation and Trading Business Units, partly offset by the better performance of the Smart Infrastructures Business Unit.

  The EBITDA of the Generation & Trading Business Unit amounted to 202 million euro, a decrease of 22 million euro compared to the first quarter of 2025.

  The change is mainly attributable to:

  • the growth in renewable production, driven by the increase in hydroelectric production due to greater hydraulicity in Calabria, the contribution of new photovoltaic and wind plants that entered into operation in 2025 and the first quarter of 2026 and the repowering of existing assets;

  • the positive contribution of trading portfolio. These effects were more than offset by:

  • the decrease in energy commodities price, despite the rise in March due to growing geopolitical tensions. In fact, in the period, the PUN decreased by 6% (from 138.0 €/MWh in the first quarter of 2025 to 130.2 €/MWh in the corresponding period of 2026) while the average cost of gas at the PSV showed a contraction of 14% (from 48.4 €/MWh to 41.7 €/MWh);

  • the higher hydroelectric fees, following the Resolution of 30.12.25 of the Lombardy Region which, in allowing the temporary continuation of expired concessions, redetermined the average nominal power of the plants under concession. This increase is partly relative to previous years.

    The EBITDA of the Market Business Unit amounted to 136 million euro, an increase of 3 million euro compared to the first quarter of the previous year.

    Despite the competitive environment, EBITDA grew mainly due to the positive contribution of the electricity market, which year-on-year benefited from lower retention charges and higher volumes sold (8.1 TWh, +1.6 TWh compared to Q1 2025), mainly related to the large customer segment, partly offset by lower margins.

    The Adjusted EBITDA of the Circular Economy Business Unit amounted to 190 million euro, a decrease of 12 million euro compared to the first quarter of 2025.

    The change is mainly attributable to

  • waste treatment sector for -24 million euro, driven by: lower margins in the quarter due to the new service contract with the Campania Region for the management of Acerra WTE, the lower contribution of the Parona and Trezzo WTEs and of some treatment plants, mainly for scheduled maintenance and revamping;

  • collection sector for -1 million euro;

  • heat sector for +10 million euro, thanks to higher revenues from the sale of white certificates;

  • water cycle segment for +3 million euro, mainly due to higher allowed revenues.

The EBITDA of the Smart Infrastructures Business Unit for the period amounted to 129 million euro, up 7 million euro compared to the first quarter of 2025.

The growth is mainly attributable to the increase in allowed revenues in electricity distribution , thanks to the application of the new ROSS tariff method and the RAB organic growth., These effects are partly offset by the sale of the gas business in the Provinces of Brescia, Cremona, Bergamo, Pavia and Lodi, which occurred in July 2025.

Adjusted EBIT amounted to 372 million euro, a 9% decrease compared to the same period of 2025 (411 million euro). The change is mainly attributable to the reduction in Adjusted EBITDA and the increase in depreciation and amortization of 12 million euro mainly due to higher capex made.

Net Financial Expenses amounted to 41 million euro, down from 42 million euro in the previous year.

Adjusted Taxes amounted to 98 million euro, a decrease of 10 million euro compared to the first quarter of 2025 due to a lower tax base, with a tax rate of 29.5%.

Adjusted Net Profit attributable to the Group amounted to 221 million euro, decreasing by 11% compared to the first quarter of 2025 (249 million euro).

Below is a reconciliation between the adjusted economic results and the reported economic results shown with the inclusion of special items.

This award upheld the Region's claims regarding the reimbursement of part of the consideration relating to the 2021-2023 period, due and already paid to A2A Ambiente for the execution of the management contract of Acerra WTE, stipulated in 2018 and terminated in February 2025. Prior to the notification of the award and before its enforceability, the Region, by communication dated 7 May 2026, requested the Company to indicate whether it intended to comply voluntarily.

The Company will appeal the arbitration award within the time limits provided for by law, in order to protect its rights.

In the first quarter of 2026, capex amounted to 315 million euro, up 4% year-on-year.

Approximately 70% was allocated to development initiatives, primarily aimed at strengthening and enhancing the efficiency of distribution networks, especially electricity grids, installing further photovoltaic capacity, and supporting the growth of Circular Economy activities (development of WTEs, plants for material recovery and for bioenergy and biomethane production, collection vehicles for new awarded tenders), Further development initiatives refer to the digitalisation of the Group and the construction of the new company headquarters.

Capex of the Generation and Trading Business Unit amounted to 35 million euro (50 million euro in the first quarter of 2025). Development initiatives equalled 24 million euro, mainly relating to photovoltaic and wind power plants to accelerate the growth of renewable generation.

Approximately 11 million euro concerned extraordinary maintenance activities, of which mainly 7 million euro for thermoelectric plants and 3 million euro for hydroelectric and photovoltaic plants.

Capex of the Circular Economy Business Unit amounted to 98 million euro (75 million euro in the first quarter of 2025) and concerned:

• the waste treatment segment for 45 million euro, of which 18 million euro for WTEs maintenance and development, 11 million euro for the development of the new Corteolona WTE, and 27 million euro for other treatment plants, such as biomass and bioenergy, material recovery and OFMSW;

• the district heating and heat management segment for 27 million euro, for maintenance and development of the heat distribution network and new connections;

• the integrated water cycle segment for 14 million euro, related to maintenance and development of the water transport and distribution network, as well as for interventions and renovations of sewerage networks and water treatment plants;

• the collection segment for 12 million euro, relating to the purchase of the vehicles for the launch of the new concessions.

  Capex of the Smart Infrastructures Business Unit amounted to 109 million euro (123 million euro in the first quarter of 2025) and mainly concerned:

• the electricity distribution segment, with 77 million euro dedicated to the connection of new users, interventions on primary plants and secondary substations, on the medium and low voltage network aa well as well software upgrades;

• the gas distribution segment, with 26 million euro for the connection of new users, the replacement of medium and low pressure pipes and maintenance of gas meters;

• the e-mobility sector with 4 million euro allocated to the installation of new charging stations.

The Net Financial Position at 31 March 2026 amounted to 5,628 million euro (5,474 million euro at 31 December 2025). Excluding changes in the scope of consolidation of -22 million euro, and the share buyback of 10 million euro, the NFP amounted to 5,640 million euro. The fixed-rate share of gross debt is 79%. The duration is 5.0 years. The cost of debt remains unchanged compared to 2025 and equal to 2.7%.

During the period, the Group generated operating cash flows of 149 million euro. With reference to items other than Adjusted Ebitda:

• the change in Net Working Capital (including the change in other assets/liabilities and the use of funds) led to a cash absorption of 460 million euro, mainly attributable to the business seasonality and the increase in energy prices starting from March 2026, following the evolution of the conflict in Iran;

• the payment of net financial expenses absorbed cash of 38 million euro, up compared to the first quarter of the previous year due to the payment of the first coupon of the inaugural European Green Bond issued in January 2025.

  Capex deployed in the quarter amounted to 315 million euro, as described above.

  The changes in the consolidation scope in 2026 were positive and amounted to 22 million euro and are attributable for 25 million euro to the price adjustment received by Ascopiave for the sale in 2025 of some ATEMs relating to gas distribution.

  Finally, paymentsof 10 million euro were made as a result of the repurchase of treasury shares aimed at implementing the shareholding plan approved by the Shareholders' Meeting of A2A S.p.A. on 29 April 2025.

• acquisition of 100% of the company Renewable Adventure Cornate D'Adda s.r.l. by the company Aeb S.p.A..

The increase in net non-current assets of 108 million euro is mainly attributable to the following changes:

• an increase of 46 million euro in property, plant and equipment, of which 215 million euro of capex, mainly for the development and maintenance on electricity grids, renewable production plants, district heating and waste treatment. The increase was partially offset by depreciation for the period of 158 million euro;

• an increase of 9 million euro in intangible assets and goodwill due to capex of 100 million euro, intended for the development of information systems, gas and water networks and the maintenance of the customer portfolio. This change was offset by depreciation and amortization of 91 million euro;

    Alternative Performance Indicators (AIPs)

    In this press release, some alternative performance indicators (AIPs) not provided for by the international accounting standards adopted by the European Union (IFRS-EU) are used, in order to allow a better assessment of the performance of the A2A Group's economic and financial operations. In accordance with the recommendations of the new ESMA Guidelines published in July 2020 and applicable from 5 May 2021, the meaning, content and basis for calculation of these indicators are set out below:

  • Adjusted Revenues: alternative operating performance indicator, calculated by excluding Special Items from Revenues;
  • EBITDA: alternative operating performance indicator, calculated as the sum of "EBIT" plus "Depreciation, amortisation, provisions and impairment losses";
  • Adjusted EBITDA: alternative operating performance indicator, calculated as the EBITDA described above net of Special Items
  • Special Items: non-recurring events that occurred during the period that had an effect on the consolidated income statement (including, for example, capital gains and losses, write-downs and reversals of impairment from impairment processes, extraordinary tax effects);
  • Adjusted EBIT: alternative operating performance indicator, calculated by excluding Special Items from EBIT;
  • Adjusted Net Profit: alternative performance indicator, calculated excluding the impact of special items;
  • Net Financial Position is an indicator of financial structure. This indicator is determined as the result of current and non-current financial payables, the non-current portion of trade payables and other non-remunerated payables that have a significant implicit financing component (payables maturing more than 12 months), net of cash and cash equivalents and current and non-current financial assets (financial receivables and securities other than shareholdings).
  • Capex: alternative performance indicator used by the A2A Group as a financial objective in the context of both internal Group (Business Plan) and external (presentations to financial analysts and investors) presentations and is a useful measurement of the resources used in maintaining and developing the A2A Group's capex.
  • M&A: alternative performance indicator used by the A2A Group to represent the overall impact on the balance sheet of external growth transactions.
