This classification entails, among the others, the synthetic consolidation of Acea Energia's income statement represented in a single separate item in Acea's consolidated income statement, "Net Result from Discontinued Operations". To provide a more meaningful analysis of the Acea Group's financial performance, Acea's pro forma consolidated income statements for the periods ended September 30, 2025, and 2024 (the "Pro Forma Consolidated Statements") have been prepared. These statements simulate, using valuation criteria consistent with those adopted by the Company, the main economic effects of the Sale, restor ing, with the sole exception of dividends, intercompany transactions with discontinued operations in order to obtain a representation of the results of continuing operations as if the discontinued operations had been deconsoli dated, as well as to simulate the consolidation of Acquedotto del Fiora at equity in the first nine months of 2024. In particular, in line with the IFRIC's discussion regarding the elimination of intercompany balances between continuing operations and discontinued operations, the follo wing pro forma adjustments have been made: 1) the income statement balances for the periods in question relating to transactions between Acea group companies and Acea Energia have been reinstated, as it is believed that these operations will continue even after the disposal (such balances, where applicable, have in fact been eliminated in the consolidation process) and 2) the accounting for Acquedotto del Fiora using the equity method has been adopted starting from 1 January 2024. For the first nine months of 2025, reported revenues and EBITDA reached 2,076mln€ and 1,071mln€, respectively. 2 Includes, in addition to the Water Italy and Grids regulated businesses, the Public Lighting and Environment businesses. 3 The proforma Net Debt takes into account (i) the impact of the future payment to be received for the sale of ACEA Energia (considering the binding offer enterprise value corresponding to 460 million Euro, net cash recognised in the amount of 128.5 million Euro against ACEA Energia’s reported net cash equal to around 213.9 million Euro as at 31.12.24, in addition to the cash variations occurred during the first nine months of 2025 and the NFP reclassified under discontinued operations); (ii) as regards 2024, the sum received for the sale of the High Voltage grid to Terna in the amount of 227 million Euro (excluding ARERA’s premium which will be received in 2026) and equity consolidation of AdF from January 1st.; LTM EBITDA (Last Twelve Months) assuming the pro-forma value net of HV.

Moreover, the growth path continues via strategic projects and participation in tenders for new concessions. • Electricity: the transition towards a more resilient, efficient and digitalised distribution network continues, also facilitated by the utilisation of new technologies, starting with robotics and artificial intelligence. • Environment: successfully launched preparatory activities for the construction of Rome’s waste-to-energy plant, a fundamental infrastructure for innovative and efficient waste management. Rome, 13 November 2025 – Today’s meeting of ACEA’s Board of Directors, chaired by Barbara Marinali, approved the Interim Report for the nine months ended 30 September 2025.

Ordinary EBITDA and net profit are increasing, as are investments. These results demonstrate the effectiveness of our managerial actions: we have enhanced the company’s soundness from a financial and industrial perspective. The broad visibility we have today of the Group’s performance permits us to carry out an upward revision of 2025 EBITDA guidance”.

ACEA GROUP 9M2025 RESULTS4 Proforma Consolidated revenues amount to 2,208.2 million Euro, with an increase over 2,060.9 million Euro as at 30 September 2024, driven by the tariff growth as regards the Water Italy, Grids and Public Lighting businesses. Revenues relating to the regulated areas account for around 89% of the total, with an increase during the period of about 7%. Proforma consolidated EBITDA, at 1,083.9 million Euro, reflects a growth of 8.4% compared to 1,000.3 million Euro for the first nine months of 2024. The one-off components pertaining to the first nine months of 2025 ( 15 million Euro) refer above all to the recognition of integrated water service technical and contractual quality premiums for the period 2022-2023 (ARERA Resolutions 225/2025 and 277/2025, 25 million Euro) and other minor items (-10 million Euro). Proforma recurring EBITDA is up by 10% to 1,069 million Euro, driven by the solid contribution from the Water Italy, Grids and Public Lighting and Generation business areas. The contribution of the various businesses to consolidated EBITDA is as follows: Water Italy 57%; Grids and Public Lighting 3 2%; Environment 6%; Generation 4%; other businesses (Overseas Water, Engineering, Energy Management – including the ACEA Energia business lines outside the sold perimeter) and Corporate 1%. 95% of EBITDA refers to the regulated sectors Water Italy and Grids, and to the Public Lighting and Environment businesses. Depreciation/amortisation, write-downs and provisions, amounting to 595.7 million Euro, are up by 13% compared to the 2024 proforma figure, reflecting the investments carried out and the coming on stream of assets previously under construction, in particular in the Water Italy, Grids and Public Lighting areas . The variation also reflects the provisions for redundancy and mobility (30 million Euro) due to the initial use of the early retirement institute (Article 4, paragraphs 1-7 ter of Law no. 92/2012, as subsequently amended ). This tool offers an opportunity to support the renewal process , promoting the entry of new professional skills and the adaptation of existing competencies, giving rise to a generational turnover in keeping with the Group’s strategic requirements. Proforma consolidated EBIT, at 488.2 million Euro, is up by 2.7% compared to 9M2024. This increase reflects the growth in EBITDA, partially offset by higher amortisation/depreciation, write- downs and provisions. Proforma net financial costs amount to 97.2 million Euro, compared to 93.0 million posted for the corresponding period in 2024. At 30 September 2025, the ACEA Group’s global average cost of debt is 2.04% (2.16% at 31 December 2024).

\\\\\\\\\\\\\\\ 4 Consolidated net profit amounts to 415.2 million Euro, with a growth of 45.7% compared to the first nine months of 2024. This result reflects, inter alia , the capital gain (109.2 million Euro) recognised following the sale of the High Voltage (HV) grid to Terna. Recurring net profit, at 301 million Euro, shows an increase of approximately 8%, in keeping with operational performance during the period. The tax rate at 30 September 2025, adjusted to take account of taxation on the aforesaid capital gain relating to the sale of the HV grid (taxed according to PEX regime), is 32.4%, compared to 30.1% at 30 September 2024. Gross investments carried out by the Group in the first nine months of 2025 amount to 1,009.7 million Euro, with a growth of 6.1% compared to 951.9 million Euro posted during the corresponding period in 2024. Investments were focused above all on the regulated businesses, which account for 89% of total capex (95% excluding ACEA Energia). Investments net of grants amount to around 843 million Euro (829 million Euro in 9M2024). Gross investments are broken down by business sector as follows : Water Italy 593.0 million Euro (473 million net of grants), Grids and Public Lighting 255.8 million Euro (209 million net of grants), Environment 54.3 million Euro, Generation 20.9 million Euro, other businesses (Overseas Water, Engineering & Infrastructure Projects), Corporate and ACEA Energia 85.7 million Euro. The Group’s Net Financial Debt is up by around 140 million Euro, from 4,9448 million Euro at 31 December 2024 to 5,083 million Euro at 30 September 2025. The variation is positively impacted by the cash flow from working capital during the third quarter of 2025, the proceeds of 227 million Euro deriving from the sale of the HV grid and reflects the dynamics of investments carried out, as well as the distribution of dividends and the payment of taxes. At 30 September 2025, the proforma Net Debt/LTM EBITDA ratio9 is equal to 3.39x (compared to 3.34x at 31 December 2024), in line with 2025 guidance. The debt is 80% at fixed rate and has an average maturity of 4.5 years. RESULTS FOR 9M2025 BY BUSINESS AREA • WATER Italy – EBITDA for this area, at 617.4 million Euro, shows an increase of 9.3% compared to 564.8 million in the first nine months of 2024 pro-forma. The growth reflects the operational efficiencies achieved, the trend in tariffs, the investments carried out and the premiums awarded to the ACEA Group water companies for technical and contractual quality, as well as the higher contribution of the companies consolidated with the equity method. Excluding the variations in perimeter and non -recurring events – which, in 2024, included the recognition of past tariff items (24 million Euro), and in 2025, the impact of technical and contractual premiums (25 million Euro) – the organic growth in proforma EBITDA amounts to around 8%. • GRIDS AND PUBLIC LIGHTING – EBITDA amounts to 343.4 million Euro, with an increase of 4.5% compared to 9M2024 (328.4 million Euro). The growth is mainly due to the investments carried out and the positive impact deriving from the revision of RAB monetary update method, which more than offset the reduction in WACC from 6.0% to 5.6%. 8 Net financial debt at 31 December 2024 (4,954 million Euro) has been adjusted to reflect the deconsolidation of Umbria Energy’s debt shown under “Discontinued Operations”. 9 See note on page 1.

OPERATIONAL HIGHLIGHTS 9M2025 9M2024 % change Electricity distributed (GWh) 6,973 7,054 -1% Number of PODs (‘000s) 1,677 1,667 +1% • ENVIRONMENT – EBITDA for the segment amounts to 66.7 million Euro, compared to 65.6 million Euro at 30 September 2024. The variation reflects above all the higher WTE volumes processed, also thanks to the restart of the Tern i facility, following the downtime for revamping activities during the first five months of 2024. Excluding non-recurring items the organic growth in EBITDA comes to around 3%.

The positive variation is driven by the higher energy market prices (SNP +14 Euro/MWh compared to 9M2024) and the larger volumes produced (~+117 GWh). Recurring EBITDA shows a growth of around 54%. OPERATIONAL HIGHLIGHTS (GWh) 9M2025 9M2024 % change Hydro production 272 231 +18% Photovoltaic production 211 140 +51% Thermo production 119 114 +4% Total electricity production 602 485 +24% • Overseas Water, Engineering, Energy Management and Corporate – EBITDA is positive by 7.7 million Euro (11.9 million Euro in 9M2024). OUTLOOK Notwithstanding a background of global uncertainty, caused by the geopolitical tensions in Eastern Europe and the Middle East and the US trade policies, the ACEA Group results for the first nine months of 2025 confirm a substantial growth trend, showing an improvement in terms of both EBITDA and Net Profit. Attention to the management of costs and investments continues, also via the implementation of even more effective purchasing procedures. The ACEA Group confirms its strategy of focusing on the development of sustainable infrastructures in regulated markets, with the aim of maintaining a sound financial structure and generating a positive impact on operational and economic performances . Within this framework, ACEA’s Board of Directors approved the bid received from Eni Plenitude on 4 June 2025 regarding the acquisition of a 100% share in the capital of ACEA Energia (including the 50% equity stake in Umbria Energy), with exclusion of the energ y efficiency, electric mobility, circular economy and energy management business lines. The transaction, in keeping with the strategy outlined in the 2024-2028 Business Plan, will help to consolidate ACEA’s role as infrastructure operator, enabling reinvestment of the sale proceeds for the development of regulated businesses, with special attention to the strengthening of investments for the safety enhancement of Rome’s electricity distribution grid.
