The first nine months of the year ended with strong growth in all economic and financial indicators, confirming the Group’s solidity and the effectiveness of its multi-business strategy Financial highlights Ebitda* at 1,006.8 million euro (+15.1%) Net profit attributable to shareholders* at 235.5 million euro (+10.0%) Net investments and corporate acquisitions at 593 million euro (+18.7%) Net financial debt and net debt/Ebitda* ratio show considerable improvement, coming to 4,148.9 million euro and 2.91x respectively ROI also improves, rising to 9% Operating highlights Significant contribution to growth coming from the energy sectors and the waste management area Ongoing growth in the energy customer base, now at 3.8 million, up 8.9% over 12 months Further initiatives for the green transition and increased investments in innovation, reinforcing the resilience of the assets managed Today, the Board of Directors of the Hera Group, chaired by Cristian Fabbri, unanimously approved the consolidated results at 30 September 2023. The first nine months of the year saw rising investments and record results compared to previous years, showing remarkable resilience when faced with extreme weather events in the area served and a global context that remains uncertain and continues to show widespread increases in inflation and in the cost of money. In particular, the significant investments reflect the Group’s commitment to boosting the resilience of the assets managed and its ongoing focus on projects designed to accelerate the green transition, fully respecting its corporate purpose. Cristian Fabbri, Executive Chairman of the Hera Group: “This period’s results show a relevant creation of value for all stakeholders. In the first nine months we reached over 1 billion of Ebitda, which shows a double-digit growth of 15%. We furthermore increased capex and investments by 19% and achieved a 9% return on invested capital, while continuing to reduce financial debt. All of our businesses contributed to this growth, more than 80% underpinned by Energy supply business due to a 9% increase in customer base, which reached 3.8 million, and further expansion of decarbonisation services. Another significant factor was the contribution coming from last resort markets, which we consolidated in September by winning 17 of the 18 available gas lots. Internal growth and the 5 corporate transactions carried out during these nine months were driven by innovation, resilience, decarbonisation and the circular economy. All of this contributed to an increase in shared-value Ebitda, now over 54% of total Ebitda, which continues to generate incremental benefits for all areas served. We are rapidly following the path for development set out in the business plan, by keeping our business portfolio balanced and seizing opportunities for creating value that allow us to accelerate its implementation.” Orazio Iacono, CEO of the Hera Group: “The effectiveness of our management decisions and our solid multi-business industrial strategy enabled us to achieve positive economic and financial results and, in particular, to further strengthen our leadership in the waste management sector, posting a raising Ebitda and on the back of larger volumes of waste treatments. In a partnership with ACR, which recently joined the Group, we won important concessions in the private oil&gas sector and are participating in tenders to access PNRR funds to reclaim public sites. Thanks to our positive cashflow and strong financial position, we achieved a net debt/Ebitda ratio coming to 2.91x, similar to the one seen before the sharp rise in energy prices. This financial soundness gives us all the flexibility we need to take advantage of new opportunities for development in our target markets. Finally, we are particularly proud of the recognition we received from Arera for the technical quality of our services, particularly in the water business, where we achieved the best performance nationwide.” Revenues at approximately 11 billion At 30 September 2023, revenues amounted to 10,955.0 million euro, slightly down from 14,320.1 million euro at the same date in 2022, mainly due to the decrease of energy commodity prices and lower volumes of gas sold on account of the mild weather in the first half of the year. An increase was seen, instead, in revenues thanks to the higher volumes of electricity sold, commercial development actions, Consip tenders, the safeguarded tenders awarded in electricity, “gradual protection service” lots awarded, higher revenues from “energy efficiency services” linked to incentives in residential buildings and increased activities in value-added services for customers, as well as revenues from the waste treatment business and, above all, to the M&A activity. Ebitda* up sharply to 1,006.8 million Ebitda* for the first nine months of 2023 rose to 1,006.8 million euro (+15.1%), as against 874.8 million euro at 30 September 2022. Of this increase, the contribution coming from the energy areas amounted to 111.8 million euro and the good performance of the waste management area accounted for 11.8 million euro, while 3.5 million euro came from the integrated water cycle and 4.8 million euro from the other services area. Net operating result* rises to 504.6 million euro The net operating result* for the nine months ended 30 September 2023 rose to 504.6 million euro, up 15.5% from 437.0 million euro in the first nine months of 2022, at same growth path signed by Ebitda. Net profit post minorities* up by 10% In September 2023, net profit* rose to 267.1 million euro (+7.5%), up from 248.4 million euro in the same period of 2022, and the tax rate improved to 26.8%. Net profit post minorities* rose to 235.5 million euro, up 10% from 214.1 million euro at 30 September 2022. Strong increase in capital expenditure and M&A In the first nine months of 2023, the Hera Group made net investments including M&A coming to 593.0 million euro (+18.7% compared to the same period in 2022). Operating investments, including capital grants, amounted to 514.0 million euro, up 50.7 million euro year-on-year (+10.9%), and mainly for the development of plants, networks and infrastructures including the large-scale meter replacement in gas distribution and on the purification and sewerage infrastructures.

The consolidated half-year report at 30 June shows growth in all main operating-financial indicators, confirming Hera’s financial solidity and once again demonstrating the effectiveness of the choices made by management Financial highlights Ebitda at 718.3 million euro (+13.8%) Net profit attributable to shareholders at 187.7 million euro (+2.4%) Overall investments rise to 403.4 million euro (+22.4%) Net debt at 4,145.7 million euro, down by 104.1 million euro compared to the 31/12/22 figure, with net debt/Ebitda ratio at 3x Business highlights Significant contribution to growth from the energy sectors, the waste management area and the water business Ongoing growth in the energy customer base, which rose to over 3.7 million, up 7.9% in 12 months Further development of initiatives for the energy transition and the circular economy, thanks to state-of-the-art plants and increasingly green services The Board of Directors of the Hera Group, chaired by Cristian Fabbri, unanimously approved the consolidated results for the first half of 2023. The first half of the year ended with operating results and investments up compared to the previous year, although in the first months of 2023 some of the served areas were affected by extreme weather phenomena and the uncertain global context continues to generate volatility in commodity prices, a generalised rise in inflation and an increase in the interest rates. The consolidated half-year report at 30 June, indeed, shows positive operating and financial performances, demonstrating once again the Group’s financial solidity and strength of its business model, balanced between internal and external growth and between regulated and free market activities. Cristian Fabbri, Executive Chairman of the Hera Group: “The first half of 2023 closed with substantial growth in results, with Ebitda reaching 718.3 million euro, up 13.8%, mainly due to the overall contribution coming from the energy area, which also saw an increase in services for decarbonisation, while growth in the waste management area confirms our commitment to the circular economy. The results for this half-year see us moving rapidly towards achieving the goals set out in our Business Plan and are the fruit of our consolidated multi-business strategy, which has always been geared towards combining corporate growth with the sustainable development of the local ecosystem. This is additionally confirmed by the 22% rise in investments, both for developing the Group’s industrial assets and for M&As that focus on growth towards the ecological transition, innovation and resilience. Our business model is capable of continuously innovating while maintaining strong local roots, and has allowed us to once again respect the commitments made to our shareholders, to whom a dividend up by 4.2% was paid last month, consistent with what was announced during the presentation of the Business Plan to 2026.” Orazio Iacono, CEO of the Hera Group: “The consolidated half-year financial report at 30 June shows significant growth in Ebitda, with a contribution coming from all business areas, in particular the energy sector with 239 million euro (+30%) and the waste management area with 162.9 million euro (+8%), and increased investments and M&A transactions, amounting to over 400 million euro. All of this was made possible by a significant cash generation and a solid financial position. The financial structure was further reinforced during the first half of the year by sustainable sources of financing on favourable terms, including the issue of a sustainability-linked bond, a new revolving credit line and a recent EIB loan. These initiatives allowed us to maintain our net debt/Ebitda ratio at roughly 3x, in line with the previous half-year and the targets defined.” Revenues at 8.3 billion In the first half of 2023, revenues amounted to 8,297.5 million euro, as against 8,896.0 million euro at 30 June 2022, mainly due to the drop in energy commodity prices and lower volumes of gas sold, as a result of the mild weather in the first half of the year. Revenues related to the higher volumes of electricity sold, instead, were up, thanks to commercial development actions, Consip tenders and the lots awarded in the protected and gradual protection services, as well as higher revenues from energy services, in which opportunities related to energy efficiency incentives in residential buildings and increased activities in value-added services for customers remained. A positive contribution also came from revenues in the waste management sector, due to increased treatment activities and acquisitions in the industry market. Ebitda rises to 718.3 million euro Ebitda for the first half of 2023 rose to 718.3 million euro (+13.8%), compared to 631.2 million euro at 30 June 2022. This increase is mainly due to the overall contribution coming from the energy areas, amounting to 68.1 million euro, and the positive performance of the waste management area, up by 12.2 million euro. Net operating result grows The net operating result at 30 June 2023 rose to 374.7 million euro, up 11.9% compared to the 334.9 million euro seen one year earlier. This performance remained positive even after higher depreciation and amortisation, due to the significant increase in investments, and conservative provisions for bad debts, due to the increased turnover in last resort markets. Financial charges increased, mainly due to the medium- and long-term credit lines stipulated in 2022 and the significant change in the interest rate scenario, which saw a significant increase in the cost of money. Net profit attributable to shareholders up to 187.7 million euro Net profit rose to 208.0 million euro (+3.1%), compared to 201.7 million euro in the first half of 2022, with a tax rate coming to 26.8%. Net profit attributable to Group shareholders* totalled 187.7 million euro, up (+2.4%) from 183.3 million euro at 30 June 2022. Strong growth in operating investments and Group solidity reinforced In the first half of 2023, the Hera Group made investments and corporate acquisitions totalling 403.4 million euro (+22.4% compared to the same period in 2022). Operating investments, including capital grants, amounted to 318.4 million euro, up by 31.3 million euro compared to the previous year (+10.9%), and were mainly related to the development of plants, networks and infrastructures. In addition, regulatory upgrading mainly concerned gas distribution, with a large-scale meter replacement, and the purification and sewerage area. Income statement (mn€) Jun-23 % inc. Jun-22 % inc.

The EIB loan will help improve the resilience of the integrated water cycle, energy efficiency and the management of environmental services in the areas served by Hera The European Investment Bank (EIB) has granted a €460 million loan to Hera Group. The main goals of the financing are to strengthen the resilience of integrated water services, increase the production of renewable energy, foster energy efficiency, decarbonisation and the circular economy, and bolster waste processing and collection, all in order to support Hera Group’s areas of operation on their path to a sustainable environmental transition and help combat climate change. This EU bank loan will finance over 60 Hera Group projects aligned with the EU taxonomy and in line with the objectives of the UN 2030 Agenda, helping the communities served by the Italian multi-utility on their path to a green transition closely connected to local society and industry. The EIB financing will therefore cover almost 60% of the total value of these investments (over €800 million) already planned by the company in its 2022-2026 industrial plan. Operations will mainly take place in Emilia-Romagna, but also in other areas served such as Veneto and Friuli-Venezia Giulia. In concrete terms, the EU bank resources will contribute to improving integrated water services via operations to further cut losses and renew rainwater collection and wastewater treatment facilities. Hera Group will increase its capacity for processing, recycling, and recovering waste by renovating existing collection centres and building new, cutting-edge plants for recycling plastic and carbon fibre and for the pre-treatment and storage of industrial waste. The EIB financing will also enable Hera Group to install over 370 000 second-generation smart meters in the regions concerned, as well as develop district heating and combined heat and power systems and build photovoltaic plants — even small-scale ones — to increase renewable energy production. Almost 40% of the EIB-financed investments will be made in the parts of Emilia-Romagna that were hit the hardest by the recent floods. The financed operations will improve the resilience of water services to future extreme weather events, including via the construction of underground rainwater collection tanks in areas of the Romagna coast subject to high hydrogeological risk. Elsewhere, a number of measures will be taken to make the sewerage network more resilient to flooding. The financing announced today is part of the REPowerEU initiative supported by the EIB, which will invest an additional €30 billion over the next five years to unlock €115 billion, promoting the green transition and gradually reducing Europe's dependence on fossil fuels.

This transaction represents a major new commitment made by the Group to promote the energy transition and decarbonisation in the areas it serves Only two months after the establishment of Horowatt, a NewCo between Hera Group and Orogel that within 2024 will create an innovative and sustainable agrivoltaic plant in the agricultural cooperative’s Cesena facilities, Hera’s programme for developing cutting-edge integrated solutions in the field of clean energy is making rapid progress. Hera Group finalised the acquisition of Tiepolo Srl, owned by Combigas and Greenfield Renewables (each one holding 50% of the shares), which has developed a project for constructing a solar park in Bondeno (Ferrara) capable of meeting the needs of over 5,000 households. The plant, which will have a capacity of 8.9 megawatts and will generate approximately 13 GWh/year when fully operational, is one of the Hera Group’s numerous projects aimed at producing renewable energy and already included in the Business Plan to 2026, to support citizens, businesses and public administrations in the decarbonisation and electrification of their consumption. In order to make a significant contribution to reducing climate-changing gas emissions in all localities served and accompany them towards carbon neutrality, the Group has not only allocated significant investments for the energy transition in its Business Plan but has also set up a new business unit entirely dedicated to renewable energy production and energy management.
