2023-11-10 Following Ascopiave’s partial exercise of the put option, the Hera Group, through its subsidiary Hera Comm, now holds 75% of EstEnergy, the largest energy operator in North-Eastern Italy This morning in Bologna, the Hera Group, acting through its subsidiary Hera Comm, and Ascopiave signed a deed of transfer from the latter of a 15% shareholding in EstEnergy, for a counter value of 137.5 million euro. EstEnergy is the commercial joint venture established in 2019 that with over one million customers is North-Eastern Italy’s largest energy operator. This operation results from a partial exercise of the put option held by Ascopiave on its shareholding in the company, as defined in the agreements signed between the parties when the partnership was created. An additional 8% shareholding in EstEnergy was transferred by Ascopiave to Hera Comm on 1 December 2022. As a result of today’s transaction, the Hera Group’s holding in EstEnergy rises to 75%, while Ascopiave’s falls to 25% of the share capital. The right to sell this shareholding remains unchanged, at the previously defined conditions, and the current governance rights are maintained. This transaction will allow the Ascopiave Group to improve the sustainability of its asset structure, consistently with the goals in its strategic plan, contributing to the financial coverage of medium-term investments in core and diversification activities. At the same time, the Hera Group will additionally reinforce its presence in the energy sector, where it is already the third-largest operator in Italy, with 3.8 million customers, to continue generating tangible benefits for customers and the served areas. This transaction, indeed, has made it possible to create new strategic synergies for developing value-added services and working towards decarbonisation and energy efficiency, significantly contributing to achieving the targets set out in Hera’s business plan, also in terms of environmental sustainability. 20231110_Ascopiave transfers EstEnergy shares to Hera Group.pdf 11:01:00 Nuova_Palazzina_110x150.1533218221.jpg See the press release Nuova_Palazzina_110x150.1533218221.jpg

2023-11-08 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. Respecting the goals set out in the business plan, the Group once again combined corporate growth and the creation of value for all stakeholders, as is proven by net investments and corporate acquisitions, up by more than 18% overall. 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. The good operating and financial performances once again confirm the decisions made by management, based on a low-risk policy and a solid multi-business industrial strategy, balanced between internal growth and external development, and between regulated and free-market activities. Double-digit growth was achieved, along with a 9% return on invested capital. Continuing along its path of uninterrupted growth, with the aim of providing its customers with innovative, competitive and increasingly complete solutions, the Group continued to expand the business areas in which it operates. In the waste management sector, Hera opened a second biomethane production plant in the Modena area and signed a partnership with ACR di Reggiani Albertino, a large company operating nationwide in the remediation, industrial waste treatment, industrial plant decommissioning and oil&gas civil engineering sectors. In IT-TLC, acting with Ascopiave the Group acquired 92% of Asco TLC, later merged by incorporation into the subsidiary Acantho. Finally, in the energy sector, it acquired the Ferrara-based company Tiepolo to construct a photovoltaic solar park in Bondeno, as well as 60% of the Rimini-based company F.lli Franchini, which installs thermal-hydraulic, electrical and photovoltaic systems for business clients. Lastly, Horowatt was established, the NewCo between the Hera Group and Orogel, to construct within 2024 a sustainable, state-of-the-art agrivoltaic plant at this agricultural cooperative’s Cesena facility. 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. Return on invested capital also improved, with ROI rising from 7.7% to 9%, confirming the Group’s ability to create value. The total amount of net financial debt came to 4,148.9 million euro, down 100.9 million euro compared to the amount seen at 31 December 2022, even after the payment of dividends, due to the cashflow coming from operations, the benefit in net working capital caused by the reduction in the value of gas storage compared to the record values seen in 2022, and the different energy price scenario. The Group’s financial solidity is also proven by the improvement in the net debt/Ebitda* ratio, which now stands at 2.91x, once again below the 3x reference level and in line with Hera’s traditionally prudential policy. Reduced debt and increased returns The total value of the Group’s net financial debt amounted to 4,148.9 million euro, down 100.9 million euro compared to the figure seen at 31 December 2022, fully covering the payment of dividends in June, the significant increase in investments compared to 2022 and the corporate acquisitions completed in 2023. This reduction is mainly due to the significant cashflow from operations in the first nine months of 2023 and the benefits on net working capital ensuing from the reduced value of gas storage and changes in the energy price scenario compared to the previous year. As a result, the net debt/Ebitda* ratio decreased to 2.91x, returning well below the 3x reference level, in line with Hera’s traditionally prudential policy. Financial operations, while showing an increase compared to 2022 due to the impact of financial lines that are currently no longer active and the Group’s greater need for financial flexibility within an energy price scenario that has not yet fully stabilised, benefitted from a 96.5% fixed-rate medium/long-term debt structure. Thanks to the liability management operations carried out in the first half of 2023, the financial structure was optimised in terms of cost and absolutely capable of insuring the Group against potential risks related to volatility in energy commodity markets, while guaranteeing at the same time continuity in operations and the significant investment activity planned. The use of variable-rate loans, linked to revolving bank lines, is activated exclusively for short-term needs and to manage volatility, is a particularly positive element within a context of rising interest rates compared to the previous year. Return on invested capital and on equity also improved, with ROI rising from 7.7% at 30 September 2022 to 9% and ROE increasing from 9% to 10.6%. Gas Ebitda for the gas area, which includes natural gas distribution and sales, district heating and energy services, amounted to 334.1 million euro at 30 September 2023 compared to 377.0 million euro in the same period of 2022, mainly due to a drop in volumes owing to the particularly mild weather in the first part of the year and the focus on energy saving shown by both residents and businesses. This drop was partially offset by increased volumes on last resort markets, the contribution coming from energy services and incentives for energy efficiency activities. In the month of September, the Group was awarded, through subsidiary Hera Comm and for the next two years, 17 of the 18 lots available in last resort gas markets, including 8 out of 9 areas for the last resort service and all 9 lots of the default service, which will take effect as of the fourth quarter of 2023. In the first nine months of 2023, investments in the gas area amounted to 138.1 million euro, up 33.5 million euro compared to the previous year. In particular, the largest investments were made in gas distribution, after the beginning of management of the Udine2 ATEM, following the tender, and in gas sales, involving the acquisition of new customers. Overall investments in district heating and energy services also rose. The number of gas customers reached almost 2.1 million, up (+2%) compared to the previous year, thanks to growth in both traditional and last resort markets. The gas area accounted for 33.2% of Group Ebitda. Electricity Ebitda for the electricity area, which covers electricity generation, distribution and sales, rose to 176.8 million euro, compared to 22.1 million euro in the same period of 2022, a year marked by fluctuating commodity prices. Significant growth was thus seen, in terms of both margins and volumes sold to end customers, especially thanks to commercial development in the free market, innovative offers and value-added services, and the higher margins on the safeguarded service and on 4 lots of the gradual protection services. Furthermore, 4 lots were recently confirmed in the Consip EE21 tender, for supplying electricity to PAs for 12 months beginning in 2024. Margins from services aimed at promoting the decarbonisation of customer consumption, for example by installing photovoltaic systems and promoting electric mobility solutions, also continued to grow. This context includes the recent acquisition of 60% of the company F.lli Franchini, to further increase decarbonisation services in the industrial customer segment, and the beginning of a partnership with the Orogel group to construct an innovative agrivoltaic system serving the Cesena production plant. At 30 September 2023, investments made in the electricity area amounted to 81.3 million euro, up by 28.3 million euro compared to the previous year. In distribution, investments mainly involved non-recurring maintenance and upgrading of plants and networks in the Modena, Imola, Trieste and Gorizia areas, as well as the ongoing large-scale meter replacement and work to improve the resilience of the infrastructure. In the sales area, investments in commercial activities related to the acquisition of new customers increased. The customer base, in fact, saw significant growth compared to the same period in 2022, reaching almost 1.7 million (+18.9%). The electricity area accounted for 17.6% of Group Ebitda. Water Ebitda for the integrated water cycle area, which includes aqueduct, purification and sewerage services, amounted to 209.3 million euro at 30 September 2023, up slightly (+1.7%) compared to 205.8 million euro in the first nine months of 2022. Gross investments made in the integrated water cycle area amounted to 142.0 million euro (89.0 million in waterworks, 34.6 million in sewerage and 18.4 million in purification). These funds went to extensions, reclamation and upgrading on networks and plants, as well as for regulatory adjustments mainly in the purification and sewerage areas. The main investments include, in the aqueduct, the ongoing reclamation on networks and connections, as well as specific renewal and upgrading works intended to counter the risk of water shortages linked to increasingly frequent droughts. Finally, Arera confirmed that the technical quality standards in the integrated water cycle managed by the Hera Group are among the highest nationwide, which led to the recognition of significant bonuses, in line with the Group’s track record. The integrated water cycle area accounted for 20.8% of Group Ebitda. Waste At 30 September 2023, Ebitda for the waste management area rose to 258.0 million euro (+4.8%), up from 246.2 million euro in the same period of 2022. Ebitda for waste treatment services amounted to 212.5 million (up 15.2 million), while Ebitda from collection and street-sweeping services, due to the impact of the newly awarded concessions in Modena and Bologna, came to 45.5 million (down by 3.4 million). These figures include a 15% increase in waste commercialised, due to increases in both municipal and market waste, the excellent performance of energy management, due to the higher contribution coming from the Modena and Trieste waste-to-energy plants, the changed scope of operations due to recent acquisitions, and the positive performance seen in commercial activities, which as a whole offset the increase in costs due to inflation. Throughout 2023, continuity was seen for the main initiatives set out in the business plan in terms of circular economy, from material recovery to renewable energy production. One example is the new plant for biomethane production located in Spilamberto, in the Modena area, born out of a partnership with Inalca, of the Cremonini Group. When fully operational, the capacity of the Spilamberto plant will lead to a 48% increase in the biomethane produced by Hera compared to 2022, and will contribute to achieving the Group's goal of increasing biomethane production to 30 million cubic metres per year. Thanks to the Group’s solid management policies, within a scenario marked by a slight slowdown in inflation, a drop in industrial production and increased competitive pressure in the markets in which it is present, Hera has continued to consolidate its leadership in the waste management sector. This has occurred especially in the industrial and recovery markets, by equipping its plants with the best available technologies and guaranteeing a considerable amount of growth in this sector. With roughly one hundred state-of-the-art facilities capable of treating any type of waste, the Group’s set of plants continues to represent a strategic and distinctive asset in a country that still shows major infrastructural deficiencies in this sector. Protecting environmental resources was confirmed as a priority objective for the Group in 2023, as was the maximisation of their reuse. This is proven by the special attention dedicated to increasing sorted waste collection, which rose to 71.4% at 30 September 2023, up 4.6% compared to the first nine months of 2022, thanks to the introduction of numerous projects in the areas served by the Group. Investments made in the waste management area amounted to 83.4 million euro, and mainly involved maintenance and upgrading on waste treatment plants, optimising collection centres and equipment, as well as investments for the transaction with ACR. The waste management area accounted for 25.6% of Group Ebitda. 20231108_PR Hera Group 3Q 2023.pdf 11:36:00 Nuova_Palazzina_110x150.1533218221.jpg See the press release Nuova_Palazzina_110x150.1533218221.jpg

2023-11-07 fibra carbonio_870.png The Hera Group, through its subsidiary Herambiente, and Leonardo, through its Aerostructures Division, will work together to research the recovery of carbon fibres in polymer matrix composite materials used in aircraft parts. Thanks to the innovative plant built in Emilia-Romagna by the multi-utility and the know-how developed in the Leonardo Group’s laboratories, the precious material will be recycled with positive spin-offs for sustainability and circularity. This marks the start of full-scale testing of a future industrial carbon fibre recovery activity in the aerospace sector using advanced technologies that permit its reuse as a secondary raw material. Through its academic and industrial partnerships, over the years, Leonardo has developed in-depth expertise in recycling materials and processes and, aided by the waste recycling expertise of Herambiente, Italy’s leading operator in the environmental sector, is engaged in closing a circular industry-wide supply chain in this strategic sector. Orazio Iacono, CEO of the Hera Group said: “This partnership, which is entirely consistent with the Hera Group’s goals of decarbonisation and development of the circular economy, is also strategically important in promoting short (reshoring) and circular supply chains in Italy and Europe. These pioneering projects call for alliances where each partner provides resources and expertise to assist in the green transition processes of many domestic industrial champions operating in different business sectors, such as aerospace, automotive, sailing and furniture, to name a few, and thus generate environmental, economic and social benefits for many supply chains.” Stefano Bortoli, Managing Director of Leonardo’s Aerostructures Division, said: “A partnership that not only seeks to recover and regenerate carbon fibre, but also focuses on innovation because it can consolidate and further develop know-how that will make the recycling of carbon fibre-reinforced composites even more efficient. Thanks to this agreement with Herambiente, Leonardo is even more committed to maintaining the circular value of waste, reducing the use of virgin raw materials and using recycled materials for internal applications, as laid out in the Group’s broader Sustainability strategy.” Technological research and innovation are the enabling factors for creating circular business models in line with the Leonardo Group’s sustainability strategy and international multilateral commitments. Circular models and practices are becoming increasingly key to competitiveness by supporting innovative processes and the ability to attract talent. The agreement is strategically significant since Europe is very much lacking in virgin carbon fibre production. Thus, developing supply chains capable of regenerating valuable resources locally will help support the process of European industrial self-sufficiency. Leonardo’s Aerostructures Division will give Herambiente some of the waste fibres from constructing the components of some of the best-known civil aircraft in the commercial aviation sector. To mention a few examples, the stabiliser of ATR turboprops, the fuselage and horizontal stabiliser of the Boeing 787 or, again, the tail planes of the Airbus A220. At the innovative plant under construction in Imola, near Bologna, Herambiente will subject this waste to pyro-gasification, and the (gasified) composite material resins will be separated from the carbon fibres using hot technology. This process, developed with the help of the Department of Industrial Chemistry of the University of Bologna and Curti SpA of Castelbolognese, near Ravenna, will regenerate fibre with performance comparable to new, also based on studies on the subject carried out by Leonardo. The Hera Group is one of Italy’s largest multi-utility companies, operating in the environment, energy and water sectors with more than 9,000 employees. It works daily to satisfy the multiple needs of around five million citizens located mainly in Emilia-Romagna, Veneto, Friuli-Venezia Giulia, Marche, Tuscany and Abruzzo.

2023-10-19 Biorg_CS_870.jpg Thanks to a 28 million euro investment, the NewCo Biorg, born out of a partnership between Herambiente and Inalca, has created an outstanding example of the circular economy, converting an old biodigester into a state-of-the-art plant transforming organic and food processing waste into 100% renewable methane and compost. The 3.7 mcm of green gas and 18 thousand tonnes of compost produced per year represent a significant contribution to the green energy transition The inauguration of the innovative biomethane production plant built by NewCo Biorg took place today in Spilamberto, in the province of Modena. This company is the result of a partnership between Herambiente (Hera Group), one of Italy’s largest multi-utilities and the foremost operator nationwide in the waste management sector, and the company Inalca (Cremonini Group), an Italian leader in meat production and food distribution. Thanks to an overall investment coming to approximately 28 million euro and the use of the best technologies currently available for treating sorted organic and food processing waste, when fully operational the plant produces 3.7 million cubic metres of biomethane, a 100% renewable fuel for automotive use, and roughly 18 thousand tonnes of compost every year. The ribbon-cutting ceremony was attended by the vice-president of the Emilia-Romagna Region with a mandate for the Environment, Irene Priolo, the Mayor of Spilamberto, Umberto Costantini, the Chairman and CEO of Biorg, Giovanni Sorlini and Paolo Cecchin, respectively, the CEO of the Hera Group, Orazio Iacono, and the CEO of Inalca, Paolo Boni. A state-of-the-art plant for the energy transition and the circular economy 100% renewable natural gas is produced at the Biorg plant in Spilamberto from both the anaerobic digestion of organic waste, coming from the sorted waste collection carried out mainly in Modena and the surrounding area, and waste from the processing carried out by the local agricultural industry and Inalca’s meat production process. Once refined, it becomes biomethane and can be injected into the gas network. Organic waste thus returns to the service of the community in the form of renewable fuel that, when injected into the network, fuels public and private city transport, thus helping a sector increasingly exposed to the issue of carbon dioxide emissions. The plant’s annual production, coming to 3.7 mcm of biomethane, is enough for a methane-powered car to travel 52 million km. The plant is therefore an excellent example of the circular economy, because it allows not only energy to be recovered, but materials as well. The waste coming out of the anaerobic digestion process, technically referred to as solid digestate, instead of being disposed of, is in fact recovered after being transported to the Biorg composting plant in Nonantola (Modena province), to produce compost that can be used as a biofertilizer in agriculture. This project is also an effective example of industrial synergy, with biomethane production and composting taking place in two perfectly complementary and integrated plants. Furthermore, it demonstrates that only innovation can generate competitive sustainability, not only reducing the environmental impact but at the same time creating added value for the entire livestock supply chain. Significant environmental benefits: approximately 7,000 tonnes of CO2 avoided every year Thanks to the biomethane injected into the grid and its use by motor vehicles, significant environmental benefits are also expected. Each year, approximately 3 thousand tonnes of oil equivalent (TOE) of fossil fuel will be saved, and approximately 7 thousand tonnes of CO2 emissions will be avoided. To absorb this amount of CO2, an average of 280 thousand trees would be needed. Moreover, constructing the Spilamberto plant did not involve any usage or consumption of new soil, since it is the result of the conversion of an old biodigester owned by the Municipality of Spilamberto and managed by Herambiente, thus making the most of a previously existing site. This amounts to zero square kilometres, but also “kilometre zero”, because the on-site production of compost creates added value for the entire livestock chain. Fertiliser deriving from recycled biodegradable waste and recovered food industry by-products, from the point of view of its production process and quality, guarantees equivalent or superior characteristics compared to fertiliser produced through other industrial processes, even when used in a pure form, and makes it possible to reduce dependence on foreign suppliers. Hera Group: a commitment to decarbonisation In order to formulate a concrete response and reduce climate-changing emissions, thus moving towards carbon neutrality, the Hera Group has included various development measures in its business plan to make an important contribution to the green transition and achieve its decarbonisation objectives. More specifically, the Group has reserved a key role for this sort of renewable fuel, and was in fact the first in Italy to build a state-of-the-art plant in Sant’Agata Bolognese, in 2018, for the production of biomethane from the organic portion of sorted waste collection. Approximately 20 thousand tonnes of compost and around 8 million cubic metres of biomethane are obtained annually, with a yearly saving coming to over 6 thousand tonnes of oil and a reduction in CO2 emissions amounting to roughly 14,600 tonnes. When fully operational, the capacity of the Spilamberto plant will result in a 48% increase in the amount of biomethane produced by the Group compared to the final figure for 2022 (7.7 million cubic metres produced in Sant’Agata Bolognese alone). At Group level, the goal is to increase biomethane production to 30 mcm per year by 2030. Inalca (Cremonini Group): integration and circular economy for sustainable business development Inalca has always adopted a pragmatic approach to sustainability issues, considering them as a strategic business asset and part of the company’s economic value, and has been able to create a fully integrated beef chain that includes breeding, processing and distribution. Its business model aims to fully exploit this supply chain on the basis of circular economy principles. The new biomethane production plant represents a further step in this direction and is an example of the company’s full local integration, in addition to achieving a complete valorisation of the by-products deriving from meat production activities. Through its partnership with the Hera Group, Inalca will also be able to rely on a further portion of organic fertilisers to improve the fertility of farmland and support the increasingly widespread adoption of regenerative farming techniques. Inalca, with the aim of decarbonising its activities, has for some time been self-producing approximately 90% of the energy it uses, about a quarter of which comes from renewable sources. This is possible thanks to 2 biomass cogeneration plants, 6 methane cogeneration plants, 2 biogas plants fuelled by industrial waste coming from its factories, 4 biogas plants from agricultural waste, over 22,120 photovoltaic panels installed on 13 factories, 1 biomethane plant and 1 composting plant. "In the 1990s the Municipality of Spilamberto started a plant that was necessary to dispose of sewage produced by intensive livestock farms which previously was spread across the land causing the poisoning of groundwater," - intervenes the Mayor of Spilamberto, Umberto Costantini. "Unfortunately, the plant never worked as imagined and this failure would therefore lead to a considerable waste of public money. However, thanks to Hera and the Cremonini Group, we have moved from a failure to a success story. Today Spilamberto is the best municipality in the province under Hera management in terms of quantity, quality and percentage of separate waste collection. The great effort in increasing separate waste collection made in recent years in Spilamberto and in many municipalities that have followed our example has led to a significant increase in the organic fraction of waste and the consequent need to treat it more virtuously than in the past. We are succeeding. The next challenges will be to focus on minimizing the odour impact resulting from these treatments for the benefit of those who live around it, but I am sure that Biorg will be as cooperative as it has been up to now in taking care of our plant and its surroundings. It's not enough to talk about circular economy, it has to be done, and here in Spilamberto I am happy to say that we are doing it." “The inauguration of the Spilamberto plant, born out of this partnership between Herambiente and Inalca, is a concrete example of the circular economy and environmental sustainability”, remarks the Vice-President of the Emilia-Romagna Region, Irene Priolo. “Biomethane provides an important opportunity to reduce the use of fossil fuels and alleviate the energy footprint of our region. The ecological conversion,” she continues, “requires a new model for development centred around a recognition of the enormous value of raw materials, which must be saved, and the importance of recovering waste and putting it at the core of new production processes. This is a fundamental turning point in establishing increasingly strong and effective actions to mitigate and adapt to climate change”. “This new plant intended for biomethane production, with an outstanding partner such as Inalca, represents a significant achievement for the circular economy and an additional step forward for us in producing biomethane on an industrial scale”, states Hera Group CEO Orazio Iacono. “The challenges of the future require utilities like ourselves to make an increasingly decisive commitment, which we intend to translate into concrete projects through investments that allow us to accompany citizens, businesses and public administrations along the green transition and, in this case, the environmental transition, with an increasingly well-distributed and inclusive model for the development of the social and industrial fabric. We must move forward without hesitation by transparently addressing the challenges posed by climate change and energy security, which are the crucial issues underlying our multi-business strategies. That is why we have also included in our business plana range of solutions for promoting renewable energy sources, energy efficiency, circular economy and infrastructure innovation.” “The construction of this plant, in partnership with a company such as Hera, equipped with significant know-how and advanced technology, represents an important step towards consolidating and strengthening Inalca’s integrated and sustainable production model”, explains Paolo Boni, the company’s CEO. “This new plant, in fact, makes it possible to fully valorise processing waste deriving from our production activities and is an additional step forward in the circular economy process. Furthermore, an effective industrial synergy being created with the production of biomethane and composting in two plants that perfectly complement each other, demonstrating that by efficiently combining innovation and integration processes, we can increase our level of sustainability and reduce environmental impacts, while at the same time ensuring greater value for the livestock business. Lastly, this model for partnership is consistent with Inalca’s investment strategy, aimed at building additional biomethane and photovoltaic plants on its farms, increasing its production of renewable energy and its commitment to combating climate change”. 20231019_Inauguration of Biorg production plant.pdf 14:05:00 Biorg_CS_110.jpg See the press release Biorg_CS_110.jpg

2023-09-27 The merger deed was signed today and follows the acquisition, last March, of 92% of Asco TLC by the Hera Group subsidiary and Ascopiave. The transaction will strengthen Acantho’s position in the IT-TLC sector, making it a multi-regional operator The Chairman of Asco TLC, Alessandro Aiello, and the Chairman of Acantho, Roberto Vancini, signed the deed of merger by incorporation of Asco TLC into Acantho this morning in Bologna. As of 1 October 2023, the latter company will take over the management of telephone and data centre services involving an infrastructure with 326,600 km of fibre optics owned, 4 data centres available (Imola, Siziano, Santa Lucia di Piave and San Vendemiano), and approximately 9,000 customers. This merger follows up on the acquisition of 92% of Asco TLC by Acantho, a subsidiary of the Hera Group, and Ascopiave, finalised on 14 March 2023 and a result of the public tender procedure called by Asco Holding. Following the transaction, the Acantho shareholding will have the following breakdown: Hera S.p.A. 70.16%, Con.AMI 16.84%, Ascopiave 11.35% Province of Treviso 1.65%. This transaction not only represents for the Hera Group and the Ascopiave Group a strategic step in the evolution of their ICT business portfolio, in line with their respective business plans, it will also enable the new Acantho to create significant operational and commercial synergies and to provide customers with increasingly broader, more efficient, innovative and competitive solutions in terms of both costs and sustainability. Asco TLC and Acantho, indeed, are companies that share many common features, not only from an industrial perspective, but also in terms of their path of development and the type of ICT services offered to their customers. The aim of incorporating Asco TLC's infrastructure assets and advanced expertise into Acantho is to expand the range of services offered in the IT and telecommunications sector. This will lead to growth in business activities, especially in the high-density industrial sector, where the company already operates through other business lines. More specifically, the merger will help improve supply relationships with citizens and companies in the geographical areas served, enabling Acantho to offer commercial proposals that use the most advanced current technology. These proposals will be integrated and made flexible, to meet the different needs of customers and stakeholders, including high-performance and reliable connectivity, telephone and data centre services. “We are excited to announce the completion of the merger by incorporation of Asco TLC into Acantho, which marks a significant step in our strategic growth and development.

2023-07-27 The merger leads to the strengthening of Acantho's position in the IT-TLC sector: thanks to Asco TLC's cutting-edge skills and infrastructure, the digital company expands its assets and services, becoming a multi-regional operator able to provide its customers with more innovative, efficient, reliable and competitive solutions, both in terms of cost and sustainability. The Hera Group and the Ascopiave Group have today approved the merger of Asco TLC into Acantho at the extraordinary shareholders' meetings of the subsidiaries held today. The expected contribution to the growth of Acantho's EBITDA, and thus to the Hera Group's consolidated EBITDA as parent company, is at least EUR 4 million, to which the resulting synergies will be added. The merger follows the acquisition of 92% of Asco TLC finalised by Acantho and Ascopiave on 14 March 2023 and the previous awarding of the public tender procedure called by Asco Holding. Asco TLC, a company active since 2001 in the provision of ICT services mainly to corporate customers and public administrations, has a significant proprietary territorial network, located in the Veneto and Friuli-Venezia Giulia regions for more than 2,200 km of fibre optic backbones, 56 radio links and 24 xDSL exchanges in unbundling, and provides its services to more than 2,700 customers. Acantho, the digital company controlled by the Hera Group, with over 7,000 customers, started over two decades ago, the development of a proprietary ultra-wideband fibre optic network, stretching over 238.000 km, and provides, also to the parent company and other companies, data centre, telephony and connectivity services, in particular with solutions in primary and secondary data centre management, networks connecting offices, internet access, fixed and mobile telephony, Internet of Things (IoT) applications for distribution network and meter management, radio infrastructure for meter and network node remote reading, network remote control platforms and digital transformation. There has always been a constant focus on sustainability by Acantho, which self-produces 30% of its data centre's energy needs, with a 20% reduction in CO2 emissions into the atmosphere. The merger by incorporation of Asco TLC into Acantho represents for the Hera Group and the Ascopiave Group a strategic step in the evolution of the business portfolio in the IT-TLC sectors, in line with their respective industrial plans. Moreover, it will allow the birth of a multi-regional player with significant operational and commercial synergies and important benefits also for customers, who will receive a dedicated communication as soon as the effective date of the merger will be defined, approximately in autumn 2023. The expected industrial benefits of the merger Thanks to the integration of Asco TLC's infrastructural assets and cutting-edge skills into Acantho, the Hera Group expects to expand its range of services in the information technology and telecommunications sector, with consequent commercial development, particularly in its reference territory, with a high industrial density, where it already operates with other businesses. The transaction is part of the multi-utility's development path, which aims to provide its customers with increasingly broader, more efficient, innovative and competitive solutions in terms of both costs and sustainability. In particular, the merger will bring added value to supply relations with the citizens and companies of the territories served, enabling the Hera Group to offer business proposals at the technological frontier, integrated and flexible to the various needs of customers and stakeholders, including connectivity, telephony and data centre services of high performance and reliability, also guaranteed by high seismic-resistance structures, and state-of-the-art anti-flooding, fire-fighting and alarm systems. "The incorporation of Asco TLC into Acantho, and therefore within the Hera Group, gives us the opportunity to make the most of the potential and specialist excellence of the two companies. In addition, the operational integration of the IT-TLC business activities of our multi-utility and Ascopiave will lead us to consolidate the proposal of Information and Communications Technology (ICT) services on the territory, with an increasingly tailor-made and flexible offer for customers, including the same companies controlled by the two groups. The sharing of assets, skills and solutions will also enable us to be able to respond more effectively and efficiently to the main trends in the ICT market, which is moving towards a greater demand for advanced products and integrated security services, both at network and systems level," said Alessandro Aiello, General Manager of Acantho. "The transaction we have concluded today will make it possible to harness, in the most effective way, the potential industrial synergies arising from the integration of the companies involved, in an increasingly competitive market context that requires a continuous improvement of commercial proposals for local authorities, companies and users," said Nicola Cecconato, Chairman, CEO and General Manager of the Ascopiave Group. 20230727_Merger ASCO TLC into Acantho.pdf 17:30:00 Nuova_Palazzina_110x150.1533218221.jpg See the press release Nuova_Palazzina_110x150.1533218221.jpg

2023-07-26 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. The Group continues to pursue the goals set out in its Business Plan, combining corporate growth and sustainable development, with value created for all stakeholders, first and foremost the local communities served. 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 Today, 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. In addition to creating value for all stakeholders, the increase in operating investments compared to the first half of 2022 provides evidence of Hera’s ongoing focus on improving and strengthening the resilience of the assets it manages, with positive impacts on the quality and continuity of services in the areas in which it operates. 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. Also note the resilience shown by Ebitda for regulated network services, with particular reference to gas distribution and the integrated water cycle, thanks to the increase in recognised revenues and operating efficiencies that offset the higher costs related to inflation. 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. The total amount of net financial debt came to 4,145.7 million euro, down 104.1 million euro compared to the figure seen at 31 December 2022, even after the payment of dividends. As proof of the Group’s financial solidity, the net debt/Ebitda* ratio stands at 3x, in line with its long-standing prudential policy. The Group’s financial structure has now been further reinforced and optimised, partly as a result of the liability management operations completed in the first half of the year, to enable Hera to handle any potencial new tensions in the energy markets and guarantee continuity in operations and a significant amount of investments. Gas Ebitda* for the gas area, which includes natural gas distribution and sales, district heating and energy services, amounted to 293.1 million euro in the first half of 2023, compared to 299.3 million euro at 30 June 2022. The factors responsible for this result mainly lie in the particularly mild winter and consumption habits that became more attentive to energy saving. This decrease was partly offset by a rise in volumes sold on the last resort market. The contribution coming from energy services, aimed at reducing customers’ consumption, in particular from activities supported by energy efficiency incentives such as the 110% super-bonus, still showed growth. In the first half of 2023, investments made in the gas area amounted to 89.3 million euro, up by 23.9 million euro compared to the previous year. In particular, higher investments were made in gas distribution for plants and networks in the new municipalities awarded with the ATEM Udine2 tender, while in gas sales they were aimed at acquiring new customers. In district heating and energy services, investments (mainly for new plants and network extensions) also increased overall. The number of gas customers reached almost 2.1 million, with a slight increase (0.5%) compared to the previous year. The gas area accounted for 40.8% of Group Ebitda. Electricity Ebitda for the electricity area, which includes electricity generation, distribution and sales, rose to 114.4 million euro, as against 40.1 million euro in the same period of 2022, showing significant growth (+185.3%) both in terms of margins and volumes sold to end customers, mainly due to commercial development in the free market. In addition to this, Group subsidiary Hera Comm was awarded, through tenders, 10 lots nationwide: 4 in the Consip EE20 tender for supplying public administrations in 2023, 3 in the gradual protection service to SMEs for the period from 1 July 2021 to 30 June 2024 in nine regions of Italy, 2 in the safeguarded service for the two-year period 2023-2024 in four regions of Italy, and 1 in the gradual protection service to micro-businesses for the period from 1 April 2023 to 31 March 2027. Margins for services aimed at promoting the decarbonisation of customers’ consumption, involving installations of photovoltaic systems, electric mobility and air conditioning systems, also continued to increase. The acquisition of 60% of the company F.lli Franchini, finalised in late June, was aimed at further increasing decarbonisation services for the industrial customer segment, as was the start-up of a partnership with the Orogel Group for developing an agro-voltaic plant serving the Cesena production plant. In the first half of 2023, investments made in the electricity area amounted to 48.3 million euro, up by 16.3 million euro compared to the previous year. As regards distribution, investments mainly concerned non-recurring maintenance and upgrading on plants and networks in the Modena, Imola, Trieste and Gorizia areas. The large-scale meter replacement continued, as did works to improve the resilience of the infrastructure. In the sales area, investments in activities related to acquiring new customers increased. The customer base indeed recorded significant growth compared to the same period of 2022, reaching over 1.6 million (+16.7%). The electricity area accounted for 15.9% of Group Ebitda. Water cycle Ebitda for the integrated water cycle area, which includes aqueduct, purification and sewerage services, stood at 128.6 million euro at 30 June 2023, slightly up (+2.6%) from the 125.3 million euro seen in the first half of 2022. In the first half of 2023, net investments in the water cycle area amounted to 81.2 million euro (58.8 million in the aqueduct, 23.7 million in sewerage and 10.5 million in purification), which went towards extensions, reclamations and upgrading on networks and plants, as well as for regulatory activities, mainly in the purification and sewerage areas. The main interventions include, in the aqueduct area, ongoing reclamation activities on networks and connections related to Arera’s Resolution 917/2017 on the regulation of the technical quality of the service, with specific modernisation and upgrading interventions intended to counter the risks of water shortages caused by increasingly frequent droughts. The integrated water cycle area accounted for 17.9% of Group Ebitda. Waste In the first half of 2023, Ebitda for the waste management area increased to 162.9 million euro (+8.1%), up from the 150.7 million euro recorded at 30 June 2022. Ebitda for waste treatment services amounted to 134.6 million, while Ebitda for environmental services including collection and sweeping amounted to 28.2 million euro, mainly due to the beginning of new concessions. In particular, margins coming from energy management increased, due to both a greater contribution from the Modena and Trieste waste-to-energy plants and the hedges made on energy sales, and a positive performance shown by commercial activities. The consolidation of existing commercial relationships, and the development of the customer portfolio, also benefited from the M&A transactions concluded in the last 12 months. Note in particular the recent expansion of the scope of operations in the environmental remediation and industrial waste global service sectors, thanks to a partnership with the Modena company A.C.R. di Reggiani Albertino S.p.A.®. In a context characterised by decreasing inflation, declining industrial production and increased competitive pressure in the markets served, the Group proved able to consolidate its leadership, especially in the industrial market and in reclamation, and achieve a significant amount of growth in this sector. All of this is thanks to Hera’s valid management policies and its set of plants, which continues to constitute a distinctive strategic asset, also considering that it works towards the ecological transition of the communities served. The protection of environmental resources was a priority objective in the first half of 2023 as well, as was the maximisation of their reuse. This is proven by the special attention dedicated to increasing sorted waste collection, which in the first half of 2023 rose to 70.4%, up 4% compared to June 2022. Investments made in the waste management area amounted to 48.5 million euro and were mainly related to maintenance and upgrading of waste treatment and storage plants, optimising collection centres and equipment, as well as investments for the transaction with ACR. The waste management area accounted for 22.7% of Group Ebitda. Press release H1 2023.pdf 13:13:00 Nuova_Palazzina_110x150.1533218221.jpg See the press release Nuova_Palazzina_110x150.1533218221.jpg

2023-07-17 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. Operations in the water sector will strengthen existing infrastructure, promote the reuse of water resources, and ensure the quality and continuity of service in the event of drought and extreme weather events. In the energy sector, the development of photovoltaic power plants — including small-scale ones — will enable renewable energy generation, while the installation of second-generation smart meters will improve energy efficiency. In the environmental sector, the construction and strengthening of plants will improve processing, recycling, and recovery capacity. The European Investment Bank (EIB) has granted a €460 million loan to Hera Group, one of Italy’s 40 largest companies by market capitalisation (part of the FTSE MIB) operating in over 300 Italian municipalities. 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 operation is a concrete example of the EIB’s commitment to promoting the sustainability, efficiency, and resilience of water, energy, and waste management infrastructure in Italy and across Europe,” said EIB Vice-President Gelsomina Vigliotti. “The EIB loan will also back Hera Group's efforts to strengthen the services provided in the parts of Emilia-Romagna affected by flooding to improve prevention and the resilience of water services to future natural disasters.” “This financing from the EIB — a longstanding and steadfast partner of Hera Group — will give major impetus to our strategic plan and confirms our commitment to sustainable development in the regions where we operate, particularly with reference to the goals of decarbonisation, the circular economy, innovation, and resilience, in line with our company’s mission,” added Hera Group CEO Orazio Iacono. “It is a key component of our financial strategy that, as well as further expanding the range of innovative products and instruments adopted by the group, will also help support the 2022-2026 development plan, confirming the sound nature of our business and our financial flexibility.” Strong EIB support for Italy’s water sector The EIB is the EU climate bank and one of the world's largest lenders to the water sector, with over 1 600 projects and around €80 billion in funding granted since 1958. Italy was the biggest beneficiary of EIB resources for the water sector from 2016 to 2022. The EIB financed 40 operations in the country during this period, providing a total of €2.9 billion and helping to unlock about €8.9 billion in investment. Background information European Investment Bank (EIB) The European Investment Bank (EIB) is the long-term lending institution of the European Union owned by its Member States. It provides long-term financing for sound investments that contribute to EU policy. The Bank finances projects in four priority areas: infrastructure, innovation, climate and environment, and small and medium-sized enterprises (SMEs). Between 2019 and 2022, the EIB Group provided €45 billion in financing for projects in Italy.

2023-07-06 This transaction, strongly linked to the local social and industrial fabric, 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. This morning, 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 the Hera Group, combating climate change is crucial and translates into a strong focus on the energy transition in all strategic areas of development outlined in our Business Plan to 2026”, comments Orazio Iacono, CEO of the Hera Group. “These concrete initiatives promote renewable energy sources, from photovoltaics to new models of distributed power generation and from hydrogen to biomethane, which will play an increasingly important role in the process towards the decarbonisation and energy security of our country. Once again, Hera’s contribution will be crucial for the sustainable development of all local areas in which we operate.” 20230706_Hera Group acquires Tiepolo to build photovoltaic power station.pdf 10:58:00 Nuova_Palazzina_110x150.1533218221.jpg See the press release Nuova_Palazzina_110x150.1533218221.jpg

2023-06-29 Through its subsidiary Hera Comm, the Group has acquired 60% of the long-standing Rimini-based company, a reference point for technological systems and renewable energy throughout Italy, thus expanding its portfolio of solutions dedicated to business customers. This morning, the Hera Group, acting through its subsidiary Hera Comm, 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 the Hera Group 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.

2023-06-14 Hera achieves 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. Among Italy’s top companies for the last three years, Hera ranks second in 2023 thanks to its 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 and presented today in Milan at the ESG Business Conference. “We are satisfied with this recognition”, remarks Cristian Fabbri, Executive Chairman of the Hera Group, “which rewards the attention we have always paid to sustainability which is a driver of our business development strategy and is fully integrated into our corporate governance. Close ties with the local areas served are crucial for a company like ours, always aware of and attentive to its institutional and social role, which is all the more significant in today’s constantly evolving context. Local roots and focus on ESG objectives are one of Hera’s hallmarks, showing that it has 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 Hera Group’s sustainable growth is, in fact, the result of a business model that always considers the generation of value as the cornerstone of its relations with all stakeholders, from the local ecosystem and future generations to customers, shareholders, workers and suppliers. Sustainability and the creation of shared value therefore stand out as the Hera Group’s fundamental traits and define its underlying purpose, which was officially included in the Articles of Association two years ago. This made Hera one of the first companies in Italy to fully affirm its commitment to the energy transition and the circular economy, through innovation and digitalisation, as well as to promoting social equity. Sustainability at the heart of Hera’s strategies Ever since the Hera Group was founded, the full and deliberate integration of sustainability in its business strategies has been one of the key elements enabling it 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 it was among the first companies to report shared-value Ebitda, which was later explicitly included in the Business plan and in the management incentive system. 20230614 Hera Group on Top 3 of IGI 2023.pdf 15:20:00 Nuova_Palazzina_110x150.1533218221.jpg See the press release Nuova_Palazzina_110x150.1533218221.jpg

2023-05-10 The consolidated quarterly report at 31 March shows growth in the main operating-financial indicators, once again proving the financial solidity and strength of the Group’s multi-business model. Hera continues to combine corporate growth with sustainable development, confirming its commitment to creating value for all stakeholders and the local communities. 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. The consolidated quarterly report at 31 March thus highlights growth in the main indicators, once again demonstrating the Group’s financial solidity and the strength of its business model. The 20.5% increase in capital expenditures compared to one year earlier provides further proof of the Group’s ongoing focus on growth, increasing value and reinforcing the resilience of assets under management. 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. Furthermore, higher turnover was recorded in energy services, as was a rise in value-added services for customers. These increases were partially offset by lower gas sales due to the particularly mild weather. 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. The pre-tax result* amounted to 191.7 million euro, consistent with the figure seen at 31 March 2022, considering the increased weight of financial operations, mainly due to the medium- and long-term credit lines stipulated in 2022. The financial structure has now been additionally reinforced, to insure the Group against potential liquidity risks arising from market tensions and to guarantee the Group’s operations and significant activities in investments. 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. Net debt totalled 3,777.6 million euro, down 472.2 million euro from the amount seen at 31 December 2022. As proof of the Group’s financial solidity, the net debt/Ebitda* ratio dropped to 2.84x, in line with Hera’s long-standing prudential policy. Gas Ebitda* for the gas area, which includes natural gas distribution and sales, district heating and energy services, stood at 193.8 million euro, as against 202.5 million euro at 31 March 2022. This decrease was due to lower sales, mainly owing to milder weather compared to the same period one year earlier, partially offset by the contribution of energy services and higher volumes sold by the subsidiary Hera Comm on default, last resort and public administration (Consip) services. In the first quarter of 2023, investments in the gas area amounted to 49.3 million euro, up 20 million euro compared to the previous year. In particular, gas distribution saw higher investments for plants and networks in the new municipalities awarded with the ATEM Udine2 tender, while in gas sales the higher investments were aimed at acquiring new customers. The number of gas customers reached almost 2.1 million, a slight increase (0.2%) compared to the previous year. The gas area accounted for 47.2% of Group Ebitda. Electricity Ebitda for the electricity area, which includes electricity generation, distribution and sales, rose to 64.5 million euro, compared to 30.4 million euro for the same period in 2022. The first quarter of 2023 showed significant growth in terms of both margins and volumes sold to end customers, thanks to commercial development, mainly in the free market, innovative offers (relating to electric mobility, photovoltaics, heating and air conditioning) and value-added services. Contributions also came from higher volumes sold to public administrations (Consip) and the initial effects of the lots awarded last autumn in the safeguarded service for 2023 and 2024, one more lot than in the previous two years. In the first quarter of 2023, investments made in the electricity area amounted to 21.7 million euro, up 6.2 million euro over the previous year. In electricity distribution, investments mainly regarded extraordinary maintenance and upgrading on plants and distribution networks in the Modena, Imola, Trieste and Gorizia areas, as well as the ongoing large-scale meter replacement and work on improving network resilience. In the energy sales segment, investments in activities related to acquiring new customers increased. The number of electricity customers increased by 7.4% compared to the same period in 2022, reaching approximately 1.5 million. This growth occurred mainly on the free market, as a result of reinforced commercial activities. The electricity area accounted for 15.7% of Group Ebitda. Water cycle At 31 March 2023, Ebitda for the integrated water cycle area, which includes aqueduct, purification and sewerage services, amounted to 55.6 million euro, essentially in line (+0.2%) with the 55.5 million euro seen in the same period in 2022. In the first quarter of 2023, investments made in the water cycle area, including capital grants, rose to more than 47 million euro (29.8 million euro in the aqueduct, 12.4 million euro in sewerage and 5 million euro in purification), mainly involving extensions, reclamation and enhancements on networks and plants, as well as regulatory upgrading mainly in the purification and sewerage areas. The integrated water cycle area accounted for 13.5% of Group Ebitda. Waste Ebitda for the waste management area, which includes waste collection, treatment and recovery services, rose to 87.6 million euro (+11%), as against 78.9 million euro at 31 March 2022, due to increased margins from energy management, partially thanks to production in plants that returned to full operations during the first quarter, and recent acquisitions in the industrial waste treatment sector. These positive effects more than offset the higher purchase prices of consumables and an increase in treatment and transport costs. Thanks to its excellent set of roughly one hundred state-of-the-art plants, capable of treating any type of waste, which continues to represent a strategic and distinctive asset on the market, the Group was able to seize further opportunities for growth, confirming its ability to react with great resilience to the market context. It thus expanded its market shares in industrial waste treatment (+27%, volumes treated), also benefiting from an enlarged scope of operations thanks to M&A transactions. In particular, note the recent partnership with the Modena-based company A.C.R. di Reggiani Albertino S.p.A.®, which enabled Hera to consolidate its leadership in the waste management area and has led to the birth of Italy’s largest operator in the environmental remediation and industrial waste global service sector, with widespread coverage throughout the country. Moreover, in the first three months of 2023, all main initiatives in the circular economy continued, from material recovery to renewable energy production. Also note the beginning of operations at the new biomethane production plant in Spilamberto (Modena), in a partnership with the Cremonini Group company Inalca. Following the NRRP grants awarded to construct platforms for material recovery, including in niche segments such as rigid plastics recycling and carbon fibre recovery, the Group was awarded further funding for upgrading and digitalising collection centres and “smart” facilities in the areas served, which will make it possible to optimise waste management services by making them increasingly innovative and efficient. Sorted municipal waste reached 70.7%, up 4.5 percentage points compared to the previous year, thanks to the development of projects in the areas served by the Group. In the first quarter of 2023, investments in the waste management area amounted to roughly 20 million euro, mainly involving maintenance and upgrading on waste treatment plants. The waste management area accounted for 21.4% of Group Ebitda.

2023-05-04 The multi-utility’s 2022 Sustainability Report confirms its commitment to a just transition. Pursuing carbon neutrality, regenerating resources, enabling resilience and innovating remain the main levers for shared value. 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 the Hera Group’s 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 The Hera Group's 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. Despite the difficulties created by a complex international context and an unprecedented energy scenario, the growth in EBITDA in terms of shared value is thus confirmed in line with the trajectory outlined in the Business Plan, projecting it to 62% in 2026, to reach a target of 70% in 2030. Significant results for the Hera Group, which for the third year running, was also awarded the S&P Global Gold Class, the highest award for listed companies in the Dow Jones Sustainability Index, where the multi-utility had been confirmed last year as sector leader in the ESG (environmental, social and governance) dimensions. Pursuing carbon neutrality Transition and promoting energy efficiency continue to be at the heart of the Hera Group's strategies. This is the direction that is being pursued at a rapid pace for the commitment to increase sustainable sources of energy. One example is the production of biomethane from the organic fraction of waste, at the Sant'Agata Bolognese and Spilamberto plants (in partnership with the Cremonini Group's Inalca company): the Hera Group intends to almost quadruple this by 2030, to reach 30 million cubic metres per year. Furthermore, the multi-utility achieved 100 per cent renewable electricity to power internal consumption a year ahead of schedule. Other important initiatives include the development of hydrogen as an energy carrier and the production of energy from photovoltaics. The Group's objective is to have more than 90 MW of installed photovoltaic power by 2026, which, when added to the systems installed at customers' premises and the energy communities that Hera is helping to develop, will provide 150 MW. With regard to total greenhouse gas emissions, the multi-utility has already reduced these by 11.7%, compared to 2019, with a target of -37% by 2030; a target validated by the prestigious international network “Science Based Targets Initiative”. In addition, the ISO 50001 certification on energy management for 11 Group companies, where 96% of the multi-utility's energy consumption takes place, is also proof of the strong focus on energy efficiency in all activities carried out and in servicing apartment buildings, companies and the public administration. Regenerating resources and closing the circle The environment is another fundamental driver guiding the Hera Group's objectives and actions. The multi-utility has always worked to regenerate natural resources, promote their more sustainable use and close the circle on the circular economy. Local collections, collections from homes, and ecological stations are the cornerstones of its urban waste management system, which focuses increasingly on the recovery of materials: 57% waste recycling had already been achieved by 2022 in the territories serviced, exceeding the EU target for 2025. Aliplast recycled more than 79,000 tons of plastic, 33% more than in 2017, the year when the multi-utility signed its commitment to reduce plastic waste pollution, in the scope of the Ellen Mac Arthur Foundation initiative. The aim is to further increase these volumes to around 150,000 tons by 2030. The integrated and sustainable management of water resources follows the same approach. As Italy's second largest operator in the integrated water cycle, from abstraction to drinking water and distribution, from sewage systems to purification, the Hera Group bases its care of water on circular management. In addition to guaranteeing quality and consistently controlled tap water using a system based on excellence, it also promotes reuse. Examples of this are the important protocols signed with the Emilia-Romagna Region and the decontamination consortia, and the experimental project at the Cesena plant for re-using purified water for agriculture. A focus and the protection of water start by setting a good example: in 2022, the multi-utility recorded a 20.5% reduction in its internal consumption (about 315.1 million cubic metres saved since 2017), with a target of -25% by 2030. Enabling resilience and innovating Ensuring service continuity and the availability of resources means first and foremost, having intelligent installations and sensitive networks. The Hera Group is well aware of this, having made digitalisation and business innovation its strategic assets: last year alone, the multi-utility invested € 102.8 million in innovation. In the critical context of water availability, the water service has shown its resilience by ensuring service continuity (without rationing drinking water) in all territories, with interventions aimed at mitigating the risk of drought and also interventions on infrastructure, with the construction of new wells and reservoirs, aqueduct interconnections, and the upgrading of withdrawal points, including the upgrading of the Po river pumps in Ferrara: investments of € 30 million are planned for this type of intervention by 2026 in the Triveneto and Emilia-Romagna regions. Community resilience also means working to promote social inclusion and the creation of shared value in the communities serviced: purchases from local suppliers in the past year amounted to € 881 million (65% of the total). More specifically, value relating to social cooperatives amounted to over € 82 million (+14% compared to 2021) and enabled the employment of 899 disadvantaged persons, with a consequent benefit for the public administration that can be estimated at over € 3.8 million. Central to this is the support provided to households: in 2022, around 272,000 bills (+36% compared to 2021), worth € 354 million, were paid in instalments. The significant increase, both in terms of numbers and value, confirms the Group's commitment to allowing payments by instalments, which has been and continues to be at significant levels in recent years. In addition, there are 135 Municipalities that have signed a Memorandum of Understanding to avoid the suspension of supplies to households experiencing economic difficulties monitored by Social Services (26 more protocols signed in 2022 in Modena, Ferrara and Bologna). 20230504_Hera Group_Over € 2.3 billion for the territories in 2022.pdf cover_BS_2022_110x150.jpg See the press release cover_BS_2022_110x150.jpg
