Hera’s Ordinary and Extraordinary Shareholders Meeting, chaired by Executive Chairman Cristian Fabbri, was held in Bologna to approve the 2023 financial statements and the payment of a dividend increasing to 14 cents per share, in line with what was previously announced during the presentation of the 2027 Business Plan and based on the significant results achieved. The 2023 Sustainability Report was also presented during the Meeting. 2023 financial statements approved with record results The Shareholders Meeting approved the 2023 financial statements, which showed strong growth in the main operating and financial indicators compared to both the previous year and to pre-crisis levels (FY2021). Among the main results: adjusted Ebitda rose to 1,494.7 million euro (+15.4%) and adjusted net profit attributable to shareholders amounted to 375.2 million euro (+16.5%). Gross operating investments reached 815.8 million euro (+15.0%) and were mainly allocated to innovation and resilience of the assets managed, the circular economy and the energy transition, with concrete projects consistent with the foremost national and international policies. Net debt fell to 3,827.7 million euro, as against 4,249.8 million euro at 31 December 2022. The financial structure thus improved significantly, with the net debt to adjusted Ebitda ratio dropping to 2.56x, compared to 3.28x for the previous year, well below the Group’s prudential parameters. Dividend payment confirmed, rising to 14 cents per share The Shareholders Meeting approved the Board of Directors’ proposal to distribute a dividend coming to 14 cents per share, up 1.5 cents over the last dividend paid (+12%). The ex-dividend date was set at 24 June 2024, with payment as of 26 June 2024. The dividend will be paid to the shares recorded on 25 June 2024. Sustainability Report: shared-value Ebitda and investments rise The 2023 Sustainability Report was also presented during the Shareholders Meeting, showing that improvement in operating and financial indicators goes hand in hand with the Group’s focus on sustainability and creating value in the served areas. In 2023, shared-value Ebitda, which refers to business activities that also respond to the targets on the Global Agenda, rose to 776.0 million euro, up 16% compared to the 670.3 million euro seen in 2022 and corresponding to 52% of overall Ebitda. Two new directors appointed The Shareholders Meeting also resolved to reappoint Director Enrico Di Stasi for the remainder of the term of office of the Board of Directors.

Financial highlights Revenues at 14,897.3 million euro Ebitda* at 1,494.7 million euro (+15.4%) Net profit* for shareholders at 375.2 million euro (+16.5%) Gross operating investments at 815.8 million euro (+15.0%) Net financial debt improves to 3,827.7 million euro (-10%), with Net debt / Ebitda* at 2.56x Proposed dividend rises to 14 eurocents per share (+12%) Operating highlights Strong performance from internal growth with contributions coming from acquisitions Significant contributions from the energy area, growth in the waste management sector, and network resilience pending the adjustment of the tariff return effective from 2024 Consolidation of ranking as Italy’s first operator in the waste management sector, second in water and third in energy Shared-value Ebitda rises sharply to 776.0 million euro (+16%) and shared-value investments amount to 558.4 million euro (69% of total investments) The Board of Directors of the Hera Group, chaired by Executive Chairman Cristian Fabbri, unanimously approved the consolidated financial results as at 31 December 2023 and the Report on remuneration policy and compensation paid, as well as the Sustainability report. Record year for the Group, that continues to create value for stakeholders and increase its scope of operations Thanks to effective choices made by management and the numerous development actions implemented, which also made it possible to seize market opportunities, the Hera Group closed the 2023 financial year with main operating results showing strong growth compared to the previous year. In particular, the Group leveraged its financial flexibility to successfully participate in recent last resort market tenders, and to acquire strategic assets in the waste management area. In a year characterised by an international geopolitical situation that remained unstable, with high energy market volatility in the first half of the year and prices that have not yet returned to the levels seen prior to the crisis, as well as a series of extreme weather and climate phenomena that affected the areas served, the Hera Group has continued to ensure service continuity and quality and the creation of value for all stakeholders. This concrete and transparent value was quantified through shared-value Ebitda and investments, with the data in question subjected for the fifth consecutive year to an external auditing company in order to validate these distinctive aspects of the Group’s reporting to all stakeholders. Hera pursued corporate growth and, at the same time, sustainable development, as shown by the increased investments in innovation and resilience of the assets managed, the circular economy and the energy transition, with concrete projects consistent with major national and international policies. In addition to internal growth, in 2023 Hera continued to expand its scope of operations through external development, with the aim of providing its customers with increasingly innovative and competitive solutions. Cristian Fabbri, Executive Chairman of Hera Group: “We closed 2023 with record performance in our main operating and financial indicators, achieved within a macroeconomic environment that was volatile and uncertain. Ebitda reached almost 1.5 billion, net profit attributable to shareholders grew by 16.5% and investments were up by 15%, exceeding 800 million euro. As a result, the economic value distributed to stakeholders in the areas in which we operate reached 2.3 billion euro, up 36%. We achieved these results mainly thanks to the contribution coming from the waste management and energy areas. In the energy area in particular, we achieved significant growth supported by commercial development, last resort markets and energy efficiency services. At the same time, debt fell by 10%, bringing us to a Net debt / Ebitda ratio of 2.56x, allowing the Board of Directors to propose a 12% increase in dividends, equal to 14 eurocents per share. The 2023 results thus confirm the validity of our Group’s strategic vision and constitute the solid building block of our new business plan, approved in January.” Orazio Iacono, CEO of the Hera Group: “In 2023, Ebitda exceed the targets set in the previous Plan to 2026 three years ahead of schedule. The normalisation of energy prices made it possible to reduce net working capital achieving a significant financial structure and a Net debt / Ebitda ratio of 2.56x. The Group thus regained its usual financial flexibility and can continue to seize further growth opportunities in its reference markets, still highly fragmented. Evidence of this lies in the transactions carried out in 2023, which also confirm our focus on generating sustainable growth in the local areas served. This commitment was confirmed by the increase in both shared-value Ebitda, up by 16% to 776.0 million euro, 52% of overall Ebitda, and in CSV investments, which amounted to 558.4 million euro in 2023, approximately 69% of total investments. Finally, we proved our ongoing commitment to sustainable finance, a driving force for our investment plan and confirmation of our desire to create value in the areas served, with particular attention going to objectives including decarbonisation, circular economy, innovation and resilience, consistent with our corporate purpose and the path set out by the Business Plan.”.

With Panasonic Industry Europe, the operating company of the Japanese multinational world leader in the production of electronic products and components, we renew the long-standing collaboration with the signing of a commercial agreement aimed at expanding the diffusion of the innovative NexMeter meter in the Italian gas distribution market. There are several utilities that have already demonstrated their interest in our device and further future prospects for partnerships with European operators cannot be ruled out. The collaboration with Panasonic dates back to 2019, when we launched our smart gas meter 4.0, equipped with advanced safety and leakage reduction functions, which subsequently evolved over time: since 2021 it has been made with recycled plastic components and has obtained the compatibility "stamp" for green gas mixtures such as hydrogen and biomethane. NexMeter has now been a consolidated reality for several years and has already made it possible to provide an important technical contribution within our activities. Its anti-seismic vocation has now led to over 250 thousand meters already installed mainly in Friuli-Venezia Giulia and Emilia-Romagna, areas classified as high seismic risk, and the additional functions of NexMeter in leak detection have also made it possible to intervene successfully in potentially critical situations, avoiding even serious risks to people and things. Furthermore, we have already activated the first Italian trial of introducing a mixture of methane and hydrogen into the city's gas distribution network two years ago in the province of Modena. Today the collaboration with Panasonic is further consolidated to make this innovative device available to all operators in the sector, which represents an excellent ally for decarbonisation. Starting from our know-how and consolidated experience in the field, Panasonic's technological excellence will, in fact, enrich the NexMeter device with further functions and will make available to all Italian operators a meter that exceeds national standards, with additional performances aimed not only at improving the safety and sustainability of the service, to the benefit of the end consumer, but also at making gas distribution more efficient and reducing costs, for the benefit of the distributors themselves.

Today, the Hera Group, through its subsidiary Hera Comm, was definitively awarded 7 lots (the maximum number allowed, out of the 26 into which the country is divided) in the national tender called by the Single Purchaser for the Gradual Protection Service for non-vulnerable household customers. This achievement will lead to the acquisition of more than 1 million new electricity customers, spread over 37 provinces of Italy, who will become part of the Group’s portfolio as of 1 July 2024. It also marks a significant step towards the target set out in the Business Plan to 2027. More specifically, Hera will strengthen its presence in several regions: Emilia-Romagna, Veneto, Friuli Venezia Giulia, Marche, Tuscany, Abruzzo, Lazio, Umbria, Liguria, Piedmont, Lombardy and Campania. The result of considerable experience in the sector and significant industrial synergies The Hera Group won 7 lots in the Gradual Protection Service by leveraging the experience previously gained in managing these services and its substantial industrial synergies. The new customers in the Gradual Protection Service will be able to rely on the Hera Group’s consolidated expertise in offering cutting-edge solutions in the energy sector and numerous contact channels, starting from over 200 customer helpdesks located throughout the country, which represent a point of reference to which they can turn for any request, concerning both supplies (gas and electricity) and value-added services (energy saving, sustainable mobility, solutions for businesses). For Hera, focussing on customer and local roots is fundamental: relations with local communities are, in fact, one of the company’s strengths.

The Hera Group has further strengthened its Italian leadership in the waste management sector, particularly in industrial waste treatment, thanks to the binding agreement signed today by its subsidiary, Herambiente Servizi Industriali, concerning the acquisition of 70% of TRS Ecology based in Piacenza, Emilia Romagna region. TRS Ecology has thus transferred to Herambiente its corporate branch responsible for the multifunctional waste treatment platform located in Caorso in Piacenza. With this new facility, when fully operational, Herambiente will process over 64,000 additional tons of industrial waste annually, contributing with approximately 6 million euro to the Hera Group’s consolidated Ebitda, in addition to synergies expected from the integration. The acquisition of TRS Ecology, which employs over 70 workers and serves approximately 2,700 clients, will allow Hera to expand its presence in the Northwestern Italy and create important synergies with its existing industrial hubs in Pisa, Ravenna and Vicenza provinces. The current ownership, represented by the company’s Sole Director Claudio Dodici, will remain within the new corporate structure, retaining a significant operational role. The details of the partnership The TRS facility in Caorso is authorized to treat more than 100,000 tons of waste annually and is organized into four process lines: solid and liquid waste storage; solid and liquid waste reconditioning, sorting, screening and recovery; solid waste volumetric reduction and grinding; solid and liquid waste mixing. In addition to its treatment activities, TRS Ecology can engage in storage, aimed at managing waste from environmental remediation. The Caorso facility currently processes approximately 50,000 tons of waste each year, and with the investments planned by Herambiente, it will be able to increase and streamline its activities, respecting the Group’s circular economy objectives.

Business Plan to 2027, operating and financial highlights 2027 Ebitda: 1.650 billion euro (+27% compared to 2022) Five-year investments at 4.4 billion euro Increased return on net invested capital, from 7.9% to 9.5% in 2027 Net debt/Ebitda below 3x over the period covered by the Plan: 2.7x in 2027 7% average annual increase in Earnings per Share Dividends to rise by 28% (up to 16 €cents per share in 2027) Average annual Total Shareholder Return (TSR) at 12%. Business highlights: sustainable growth 2.5 billion euro in investments aligned with the European Taxonomy for Sustainable Investments (98% of eligible investments) Shared-value investments coming to over 70% during the entire five-year plan Increase in shared-value Ebitda, up to over 55% in 2027, reaching 64% of total Ebitda Commitment to reduce total CO2 emissions by 29% within 2027 and by 37% within 2030 confirmed 30% of the investment plan goes towards digitisation and infrastructure innovation 40% of the investment plan contributes to increasing the climate-change resilience of the Group’s infrastructures 10 billion euro distributed over the five-year period 2023-2027 to stakeholders in the areas served by the Group Highlights from 2023 preliminary results Ebitda expected to rise over 1,480 million euro (+14%) Net debt/Ebitda ratio expected to settle below 2.6x (from 3.3x in 2022) Dividend expected at 14 euro cents (+12% over 2022), higher than forecast by the Plan The Hera Group’s Board of Directors, chaired by Cristian Fabbri, reviewed the preliminary results for 2023 and approved the Business Plan to 2027. Growth in all main key operating and financial indicators, from Ebitda to ROI, earnings per share and dividends, accompanies a focus on financial balance, with net debt/Ebitda ratio stably below 3x. The significant investment plan allocated for the 2023-2027 five-year period will support numerous projects and accelerate activities geared towards strengthening resilience and generating shared value and sustainable development. Hera thus confirms itself as a solid point of reference in its reference markets responding to the challenges of the external context and enabling the ecological, energy and digital transition, the circular economy and resource protection. Cristian Fabbri, Executive Chairman of the Hera Group: “4.4 billion in investments aimed at industrial development, sustainable growth and resilience underpin our projections of the Ebitda coming to 1.65 billion euro in 2027, up 28% compared to 2022, along with a dividend increase of 5% CAGR. 40% of capex plan will contribute to making our infrastructures even more resilient. A 29% reduction in carbon emissions and our commitment to resource regeneration are concrete examples of our contribution to the ecological transition, and the Ebitda generated by activities that also meet the targets set out in the UN Agenda will rise to 64%. Furthermore, over the five years covered by the Plan we will distribute 10 billion euro to the stakeholders. This Plan fully responds to our Group’s purpose: to generate sustainable value by promoting a ‘just’ transition. The record growth in Ebitda seen in 2023, which we expect to come to over 1.48 billion euro, and the considerable decrease in debt, with the net debt/Ebitda ratio expected below 2.6x, are promising indications and fundamental building blocks of this Business Plan. They are matched by the provisional awarding of more than one million customers in the Italian electricity market liberalization process, allowing us to more rapidly reach 4.3 million energy customers and to consolidate our position as Italy’s third largest operator in this sector.” Orazio Iacono, CEO of the Hera Group: “With Ebitda expected to reach almost 1.5 billion euro in 2023, and financial leverage strongly improving to less than 2.6x, we will meet and exceed the targets set out in the previous Business Plan to 2026 three years ahead of schedule. These results prove the validity of our Group’s strategic vision in seizing market opportunities and our commitment towards sustainable growth in the areas served. This commitment has been confirmed once again by our new Business Plan, with shared-value Ebitda expected to exceed 1 billion euro in 2027, showing a 55% increase in absolute terms over 2022-2027, higher than the growth rate of overall Ebitda, testifying to the growing importance of initiatives that not only generate margins for our company, but are also in line with the objectives found in the UN Agenda. More than 70% of the investments made over the time covered by the Plan will indeed be allocated to sustainability projects that benefit all our stakeholders. Regarding our various businesses, the next five years will see an important contribution to growth in the Group’s results coming from all activities, in particular the waste management sector, thanks to our strategy that leverages a portfolio of global waste services that will further strengthen our leadership in this market, and the networks sector, which will see a significant investment plan, accompanying the areas served towards the green transition.” Business Plan to 2027 The strategic objective underlying the Hera Group’s new Business Plan is to create value benefitting all stakeholders, thanks to financial, environmental and social sustainability objectives, along with a business model and an industrial structure that are resilient to the negative effects of climate change and external market crises. Creating value: 2027 Ebitda up to 1.650 billion and dividend up to 16 €cents (+28%) The projects planned will bring overall Ebitda to more than 1,650 million euro in 2027, with a 355 million euro improvement compared to the 2022 result. Taking into account a number of business opportunities that will no longer be present during the time covered by the Plan and that contributed with roughly 120 million euro to the 2022 result, the growth will reach 475 million euro with an average annual rate coming to 7%. Sustainable growth to support the ecological transition: shared-value Ebitda at 64% in 2027 and economic contribution to local areas at 10 billion euro The Hera Group has confirmed its focus on the circular economy and decarbonisation, in order to encourage and support the ecological transition of the areas served with initiatives aimed at citizens, public administrations and industrial customers, offering its extensive set of plants and the know-how it has accumulated in various business sectors. The initiatives set out in the Business Plan to 2027 make it possible to project a path that is perfectly consistent with achieving the industrial objectives to 2030 in terms of circular economy and decarbonisation. As regards the circular economy, for example, the route to be followed confirms 2030 targets such as an increase in recycled plastics (+150% compared to 2017) and the reuse of wastewater (reaching 18% of total wastewater by 2030). Balanced growth in the multi-business portfolio and increased resilience The Business Plan expects growth to be equally distributed among the three main lines of business (networks, energy and waste management), maintaining their current balance. Continuity is also expected in the Group’s development model, which has ensured a high degree of resilience in results within all scenarios witnessed over the last twenty years, allowing for uninterrupted growth in both sustainability targets and operating-financial and service performances. Total investments at 4.4 billion euro, with additional projects funded by 400 million in grants coming from the NRRP and other institutions The investment plan amounts to 4.4 billion euro, 48% of which will go to development initiatives and M&As. 55% of investments will be earmarked for regulated businesses, while the remaining 45% will support growth in free-market businesses. The over 870 million euro invested each year on average will accelerate the Group’s commitment to the ecological transition (with roughly 60% of the entire investment plan going to decarbonisation and the circular economy) and to generate sustainable development in the areas served. In this sense, more than 70% of the investment plan will be allocated to initiatives capable of creating shared-value Ebitda. In light of the introduction of the new aspects related to the European Taxonomy, the Group estimates that operational investments coming to 2.5 billion euro (or 98% of eligible investments) will be aligned with the requirements of the European framework, and will therefore be able to gain full access to subsidised sustainable finance instruments, with benefits in terms of financial costs as well.

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.

From 7 to 10 November 2023, “Ecomondo” (the European fair that acts as a reference point on ecological transition, technological and industrial innovation of environmental services and green economy, particularly waste and resources, circular bio-economy, and water) is at the Fiera di Rimini. We are there again this year, in Hall C1 at Stand 500, with a two-storey exhibition space covering 550 square metres: the entire Hera Group is present with Hera S.p.A., Herambiente, Aliplast, Hera Comm, HERAtech and Hera Luce. During the fair, the business offers of the Group's trading companies are also presented. As every year, the stand is decorated with works of art made from recycled materials by SCART, the Hera Group project devoted to the artistic regeneration of industrial waste, in full compliance with the circular economy. Once again this year, SCART presents a new project in collaboration with the Fine Arts Academies of Florence, Ravenna and Rimini and the young people from the San Patrignano rehab centre. These are 30 new works made up of waste from sports activities. Even outside the expo, it is possible to admire a Formula 1 car created with the waste collected by the Group following the floods of May 2023.

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 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.

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. For further information Press release acquisizionetiepolo_870.png This transaction represents a major new commitment made by the Group to promote the energy transition and decarbonisation in the areas it serves sede-hera-110.jpg

Acting through our subsidiary Hera Comm, we finalised the acquisition of 60% of Fratelli Franchini. Based in Rimini, this company has a consolidated experience in the area of designing, installing and providing maintenance of all types of technological systems for companies, public administrations and hospitality facilities. It has been active for over 17 years in producing high-yield renewable energy sources for public and private industrial customers throughout Italy. The remaining 40% of the company stays in the hands of Franchini Group Srl, owned by brothers Pierpaolo and Marco Franchini, who retain the position of CEOs. This partnership with a long-standing operator, active both locally and nationally, will enable us to acquire new technical skills, particularly in the photovoltaic market, expand its portfolio of solutions for business customers, and respond to the growing demand for systems based on renewable sources, further strengthening its position in the Italian energy market. The details of the partnership Fratelli Franchini boasts over half a century of activity in the system engineering sector: since 1959 it has been building technological systems and since 2006 it has also been working in the renewable energy sector, developing projects for business clients in the hotel, port, hospital, industrial, retail and museum sectors. This company is the partner of choice for clients in the industrial sector, both public and private, to whom it is able to offer integrated solutions in all phases necessary for installing and maintaining of electrical, mechanical, large-scale photovoltaic and energy efficiency systems. It has installed more than 300 systems over the years. This operation boosts our ability to support our customers along the path to decarbonisation, including through the installation of photovoltaic generation systems, from traditional photovoltaic panel systems to new distributed power generation models such as Renewable Energy Communities.

Among Italy’s top companies for the last three years, we rank second in 2023 thanks to our full and deliberate integration of sustainability policies into its business strategies and governance structure. This has been confirmed by the Integrated Governance Index, the main quantitative index measuring the integration of ESG factors in the governance of the top 100 Italian listed companies, managed by ETicaNews. Local roots and focus on ESG objectives are one of our hallmarks, showing that we have always been committed to giving full value to people, thus generating a tangible impact and helping the communities served move towards a more equitable future in environmental, economic and social terms. The Group’s sustainable growth is, in fact, the result of a business model that always considers the generation of value as the cornerstone of our relations with all stakeholders, from the local ecosystem and future generations to customers, shareholders, workers and suppliers. Sustainability at the heart of our strategies Ever since the Group was founded, the full and deliberate integration of sustainability in our business strategies has been one of the key elements enabling us to meet all its challenges, because for Hera growth and sustainable development necessarily go hand in hand. This path has been built over time, starting from the Group’s corporate culture: in 2016 we were among the first companies to report shared-value Ebitda, which was later explicitly included in the Business plan and in the management incentive system. This commitment is also shown by the launch, in April 2023, of the second Sustainability-Linked Bond and the activation of a new credit line, the Sustainability-Linked Revolving Credit Facility, thanks to which we will allocate more than 1 billion in financing for projects moving towards the green transition. For further information Press release primo_piano_IGI_2023_870.png We achieve second place in the overall ranking published by the index measuring the degree to which ESG factors are integrated within the governance of Italy’s top 100 listed companies centrata IGI_2023_110.jpg

Financial highlights Revenues at 5,628.9 million euro (+6.0%) Ebitda* at 410.2 million euro (+9.4%) Net profit attributable to shareholders* at 128.2 million euro (+0.7%) Net debt at 3,777.6 million euro, down 11% compared to 31 December 2022, with net debt/Ebitda* at 2.84x Business highlights Good contribution to growth coming from all main businesses, the energy and environment sectors in particular Further development of initiatives for the ecological transition and the circular economy through state-of-the-art plants and increasingly green services Ongoing growth in the energy customer base, reaching almost 3.6 million Today, the Board of Directors of the Hera Group, chaired by Cristian Fabbri, unanimously approved the consolidated results for the first quarter of 2023. For the Hera Group, the first quarter closed with improved operating results and investments compared to one year earlier, even though the scenario still shows a considerable amount of uncertainty, with effects on the commodity prices and a slowdown in production and international trade. Both internal and external growth drivers in Hera’s multi-business portfolio enabled it to achieve an excellent operating and financial performance while pursuing the creation of value for all stakeholders. Cristian Fabbri, Hera Group Executive Chairman: “The first quarter of 2023 closed with increased operating results, supported by the positive performance of the free-market energy and waste management businesses. We have thus confirmed our ability to gain new market shares, to provide services that are favoured by customers, and effectively leverage upon our competitive advantages in all our activities. The significant positive cash flow over the first quarter allowed us to reduce our debt and significantly improve the net debt/Ebitda ratio, which now stands at 2.84x.” Orazio Iacono, Hera Group CEO: “The positive operating cash flow of Q1 was able to fully cover a significant increase both in capital expenditures and investments which mainly concerned strengthening the infrastructures and plants managed, to the benefit of the quality of services provided to the customers as well as the resilience of our infrastructures and plants. We also strengthened and optimised our debt structure, thanks to the recent issue of a sustainability-linked bond worth 600 million euro and the simultaneous subscription of a 450 million euro sustainable revolving credit line. These are two additional milestones in sustainable finance and will lead us to allocate more than 1 billion euro in financing to green transition projects, to achieve the goals on the 2030 Agenda with concrete initiatives and respond to the challenges of a sustainable transition rooted in the social and industrial fabric. This operation, particularly appreciated by the market, guarantees additional financial flexibility.” Revenues amounting to over 5.6 billion In the first quarter of 2023, revenues amounted to 5,628.9 million euro, up 6% from the 5,312.0 million euro seen in the same period of 2022. The energy segments above all contributed to this result – mainly due to the higher volumes of electricity sold as a result of reinforced commercial initiatives and the safeguarded lots awarded last autumn – and the waste management area, partially due to acquisitions in the remediation and industrial waste treatment market. Ebitda* rises to 410.2 million Ebitda at 31 March 2023 rose to 410.2 million euro, +9.4% compared to 375.1 million euro in the first three months of 2022. This positive growth was mainly due to the overall contribution coming from the energy areas and the good performance of the waste management area. Increased net operating result* and stable pre-tax result* Ebit* at 31 March 2023 increased to 236.1 million euro, up 6.7% from 221.2 million euro in the first quarter of 2022. This performance was positive even after higher depreciation and amortisation due to the significant increase in investments and provisions for bad debts resulting from the increase in turnover, including last resort markets. Net profit* rises to 140.3 million euro Thanks to a tax rate coming to 26.8%, down from the previous year, net profit* rose to 140.3 million euro (+1.2%), as against 138.6 million euro in the first quarter of 2022. Net profit attributable to Group shareholders* settled at 128.2 million euro, up +0.7% from 127.3 million euro at 31 March 2022. Sharp increase in operating investments and Group solidity reinforced The Group’s capital expenditures, including capital grants, amounted to 155.7 million euro, up sharply (+20.5%) compared to 129.2 million euro at 31 March 2022, and mainly involved work on plants, networks and infrastructures. Regulatory upgrading, instead, mainly concerned gas distribution, with a large-scale meter replacement, and the purification and sewerage area.

Reporting with clarity and transparency on the results achieved, sharing the challenging objectives on which corporate choices are based with stakeholders and, above all, striving to make people, needs and the enhancement of territories our focus: these criteria once again form the basis underpinning our 2022 Sustainability Report. As in 2021, the document also includes a report on all activities in accordance with the EU taxonomy of environmentally sustainable activities, with particular reference to climate change mitigation and adaptation objectives. In total compliance with Brussels and the primary international policies, the multi-utility thus continues its path towards change, combining climate action and social inclusion, in the belief that no step forward can be sustainable unless it is fully endorsed by everyone. Creating value together with communities: over € 2.3 billion distributed in the serviced territories Our sustainable growth is the result of a business model that continues to enhance people and support the communities it services towards a more just future in environmental, economic and social terms. Compared to 2021, total economic value for stakeholders rose to more than € 3 billion: this includes employees (601.1 million), shareholders (236.3 million), the public administration (151.8 million) and suppliers (approximately 1.4 billion). Over € 2.3 billion of this amount, or 76%, is distributed in the territories serviced, where the multi-utility guarantees service continuity and efficiency, with significant investments to innovate its infrastructure assets, which will be decisive in meeting climate challenges in coming years. Shared-value EBITDA also increased: € 670.6 million (+17%) Among the most significant achievements, the shared-value Gross Operating Margin (EBITDA) - i.e., referring to business activities generating environmental and social benefits in the three areas of carbon neutrality, the circular economy, resilience and innovation - rose to € 670.6 million (+17% compared to 2021) or 52% of total EBITDA, with an improvement across all target parameters. In other words, it means making what has been done even more sustainable and continuing to grow, evolving the business in the right direction.
