Rendering NexMeter With the Hera Group, also gas distribution is going green. NexMeter, our smart gas meter 4.0, the first of its kind worldwide in terms of cutting-edge technology and safety functions, including reducing gas dispersion into the atmosphere, will be made from recycled plastic and can already be used for distributing hydrogen in the network up to a maximum of 20% compatibility, with a trial planned in the coming months. This advanced meter is therefore a concrete example of our commitment to the energy transition and carbon neutrality, focusing on green gases, such as biomethane, hydrogen and green syngas, and contributing to the fight against climate change. Furthermore, it results from Hera’s experience and know-how in management of the gas distribution service, combined with continuous investments in innovation, research and development, and confirms the Group’s collaboration with outstanding partners: Panasonic, the Japanese multinational global leader in electronic products and components, and Pietro Fiorentini, an Italian company and market leader in creating products and services for the entire natural gas chain. The advanced version of NexMeter will be previewed today in Milan at Enlit, the most important event in the sector. An immediate debut: initial experiments with hydrogen in the domestic gas network soon to be underway NexMeter’s first field test involving hydrogen will be carried out during the next few months, as part of a wider set of activities aimed at certifying our entire supply chain as qualified to use green gases. More specifically, it involves introducing a mixture of natural gas and hydrogen into a portion of the distribution network managed by the Group, involving around thirty households in Castelfranco Emilia in Modena province. This is the first experiment of this kind in Italy as regards domestic gas distribution, and it aims at studying innovative solutions to contribute to the local area’s needs as regards decarbonisation, with benefits for the environment as well. The trial is also part of the broader strategy for developing hydrogen in a two-fold perspective: on the one hand, upgrading our assets, starting with the gas distribution networks, and on the other, creating new business opportunities, which we can make the most of by leveraging its multi-business expertise, including partnerships with other major industrial operators.

Bologna The Emilia-Romagna Territorial Agency for Water and Waste Services (Atersir), acting as regulatory agency and contracting station, has officially awarded the tender for urban and assimilated waste management in the Bologna area to the temporary consortium (RTI) formed by Hera S.p.A., Giacomo Brodolini Soc. Coop and Consorzio Stabile Ecobi. The figures of the tender won by the consortium led by the Hera Group The contract awarded concerns 50 municipalities in the Bologna area, including the capital city, and a total of approximately 1 million inhabitants. As requested during the tender, the temporary consortium led by the Hera Group – the current manager of the service in the same municipalities – will make significant investments to extend the ‘pay as you throw’ waste collection model to the entire area, with the aim of minimising the amount of non-sorted waste and increasing the quantity destined to be recycled. The contract, which will be signed in the coming weeks by Hera and Atersir, has a total value of over 1.7 billion euro and a timespan of 15 years. More sustainability and increasing shared value for communities Thanks to the excellent operational skills of Hera and the other companies in the contracted consortium, the area covered by the service contract will be provided with collection methods based on innovative services and equipment, strongly oriented towards sustainability, waste reduction and an increase in the amount of recycled materials. More dialogue and better environmental performance The key principles underpinning the offer presented by the consortium led by Hera are awareness-raising and the active involvement of citizens and businesses, in order to encourage a reduction in the amount of waste, especially non-sorted waste, and an increasing focus on sorted waste collection. In fact, experience in this field shows that – regardless of the collection method proposed – the environmental performance of waste is better where the community is more aware of its role. For this reason, right from the first months of the new service contract, Hera will launch progressive communication and information campaigns aimed at increasing citizen involvement, and in so doing, further improving the service quality, with a view to creating increasing shared value for local communities.

Risultati finanziari Financial highlights Revenues at 6,424.3 million euro (+31%) Ebitda at 883.3 million euro (+9.6%) Net profit for shareholders at 308.4 million euro (+32.3%) Net financial debt at 3,303.8 million, with Net debt/Ebitda at 2.75x Operating highlights Strategy based on a mix of internal and external growth Significant contribution coming from the gas area, energy services and the waste management sector Over 3.4 million energy customers reached Today, the Hera Group’s Board of Directors, chaired by Tomaso Tommasi di Vignano, unanimously approved the consolidated quarterly report at 30 September 2021. The report shows improvement in the main economic indicators compared to the same period of the previous year, confirming the Group’s long track record of positive performances, its financial solidity and its commitment to sustainable development, respecting European strategies and the UN 2030 Agenda. The most significant results include an increase coming to over 77 million euro in Ebitda, mainly owing to free market activities – especially gas sales, energy services and waste treatment – whose pro-cyclical nature enabled the Group to take full advantage of the opportunities arising from the country’s economic recovery and revival initiatives, while at the same time creating value for the local areas and communities served. A sharp increase was also seen in net profits for shareholders, which in this quarter includes the effects of the tax realignment of certain goodwill items. In July, a dividend amounting to 161 million euro was paid to shareholders, corresponding to 11 cents per share, up 10% compared to the previous year. From a broader point of view, the results for the first three quarters of the year show growth not only with respect to 2020, but also compared to the results for 2019, prior to the impact of the global pandemic. The current results are higher than the expectations contained in the Business Plan to 2024: in less than two years, Hera has achieved more than half of the growth forecast for the five-year period covered by this Plan. The Group’s strategy therefore continues to prove successful, promoting both organic growth and mergers and acquisitions, and protecting results achieved from the turbulence seen in the external context. The more noteworthy changes in the scope of consolidation include three M&A transactions in the industrial waste treatment area, with the acquisition of 70% of the Friuli-based company Recycla, 31% of the company Sea, located in the Marche, and 80% of the Vallortigara Group, which operates in the Veneto region. The energy areas, instead, saw the acquisitions of Wölmann, a company operating in photovoltaic panel installation, the sales company Ecogas, in Abruzzo, and 11% of Ascotrade from the Belluno company Gsp, thus arriving at 100% control. At the same time, continued growth was seen in the Group’s energy customer base, now over 3.4 million, thanks to increases in both liberalised markets and those subject to public tenders. Lastly, as regards regulated services, the Hera Group has won the tenders called to date in the areas served, in the waste management, gas distribution and integrated water service areas. Note in particular the recent confirmation of gas distribution in the Udine 2 ATEM and, last week, in the water cycle, serving 24 municipalities in the province of Rimini, including the city of Rimini. Revenues rise to over 6.4 billion euro In the first nine months of 2021, revenues amounted to 6,424.3 million euro, up 31.0% from 4,905.9 million-euro one year earlier, with growth seen in all areas. More specifically, the energy areas felt the effects of higher revenues from trading, higher volumes of gas sold and an increase in the price of energy commodities, in addition to the energy services business, due to the activities related to the insulation incentive and energy efficiency works. Revenues from network services (both regulated and on behalf of third parties) and the waste management area also increased, due to energy production, more waste treated and an increase in plastics sold. Ebitda increases to 883.3 million euro Ebitda increased by 77.1 million, or 9.6%, over the 806.2 million seen in the first nine months of 2020, rising to 883.3 million at 30 September 2021. This increase is linked to the performance of the energy areas, mainly thanks to gas sales and energy trading, as well as energy service activities. Another decisive factor consisted in the positive results recorded in the waste management sector, particularly in the waste treatment area. Operating result grows to 470.8 million euro Operating profit rose to 470.8 million euro, compared to 414.7 million at 30 September 2020, showing a 13.5% increase (despite higher expenses for depreciation and amortisation). Financial operations at the end of 3Q 2021 amounted to 85.4 million euro, mainly due to lower income from late payment indemnities on last resort markets and higher charges for the sale of tax credits as part of ecobonus-related activities. These aspects were partially offset by the efficiencies achieved following the repurchase of part of the medium- to long-term debt, lower updating expenses and higher profits from subsidiaries and joint ventures. Pre-tax profits increased from 335.2 to 385.4 million euro (+15%). Net profit for shareholders rises to 308.4 million euro Net profit rose to 340.6 million euro, up significantly by 39.2% from 244.7 million euro in the same period during the previous year, thanks to a tax rate that settled at 26.2%, improving compared to the 27% recorded at 30 September 2020, due to the Group’s commitment to supporting substantial investments in technological, digital and environmental transformation towards Utility 4.0. The increase is also linked to the amount consisting in special items, which contributed with 56.2 million euro, as result of the tax realignment of certain goodwill items recorded in the financial statements, offset by the expenses arising from the partial repurchase, last spring, of a 700 million euro bond maturing in 2028. Net profit post minorities also increased sharply, rising to 308.4 million euro from 233.1 million euro at 30 September 2020 (+32.3%). Operating investments at 377.2 million euro and stable net financial debt In the first nine months of 2021, Hera made operating investments coming to 377.2 million euro, an increase of over 13% compared to the 333.6 million euro seen in the same period of the previous year, with an important focus on the projects, including green initiatives foreseen in the Business Plan. These investments were mainly allocated to plants, networks and infrastructures, as well as regulatory upgrading in purification and sewage and a large-scale installation of new-generation gas meters. In addition to financing these investments and paying increased dividends, the positive cash flow generation also made it possible to cover the repurchase of maturing bonds and a large portion of the M&A transactions, keeping net financial debt essentially stable at 3,303.8 million euro in the first nine months of 2021, in line with the 3,227.0 million euro seen at 31 December 2020. Hera’s financial strength – which is also clear from the assessments made by the main rating agencies: BBB+ with stable outlook from Standard & Poor’s, Baa2 from Moody’s - is also confirmed by the Net debt/Ebitda ratio, which stood at 2.75x, an improvement compared to the 2.87x seen at the end of 2020 and 2.97x at 30 September 2020. These aspects go hand in hand with the pursuit of sustainable development, as confirmed by Hera’s recent inclusion in the MIB ESG Index, Italy’s first blue-chip index dedicated to Environmental, Social, and Governance (ESG) best practices. In October, furthermore, Hera successfully launched its first sustainability-linked bond, worth 500 million euro, gathering great interest from international investors, who subscribed with roughly four times the amount offered. This bond is part of a sustainability strategy aimed at reducing emissions and recycling plastics. At the same time, after the end of the quarter, the Group carried out a liability management transaction to repurchase nominal 350 million euro in financing maturing in the next few years, with effects that will be recorded at year-end.

Herambiente acquires Vallortigara Group The Hera Group has further strengthened its national leadership in the waste management sector, more specifically in industrial waste treatment. The Group, through its subsidiary Herambiente, has in fact acquired 80% of the Vallortigara Group, which provides services to industries, public administrations and citizens and manages a multifunctional platform for special waste treatment in Torrebelvicino (Province of Vicenza in the North-Eastern part of Italy). The Torrebelvicino platform consists of three sections: a storage and selection plant for solid and liquid, hazardous and non-hazardous industrial waste, a stabilisation and solidification plant for industrial sludge and a chemical-physical plant for liquid waste. Currently, this facility treats approximately 75,000 tonnes of waste per year and, thanks to the investments planned by Herambiente, it will be able to increase and streamline its activities, in line with the principles of the circular economy. The acquisition of the Vallortigara Group, which employs over 100 workers and has 4,000 customers,both in public and private sector, will enable the Hera Group to strengthen its presence in the Triveneto region. also expand its service to neighbouring territories, creating significant synergies with the Hera Group’s industrial centres in the provinces of Pisa and Ravenna, which have been operational for some time. The current owners (the Vallortigara family) will remain within the new corporate structure. Overall, through the company Hasi (Herambiente Servizi Industriali), Herambiente now has 18 multi-purpose sites dedicated to treating waste produced by businesses, with 1.3 million tonnes of industrial waste treated each year. Following the two transactions in the same field, industrial waste treatment, carried out in the first half of 2021 – the acquisition of 70% of the company Recycla in Friuli and 31% of the company SEA in the Marche region – Herambiente’s development plan thus continues, confirming its position as the country’s leading operator in the sector, able to provide across-the-board solutions in industrial waste treatment to an increasing number of new customers.

Potabilizzatore Val di Setta Hera’s Sasso Marconi (BO) drinking water plantcertified by the AWS (Alliance for Water Stewardship), the leading international standard that encourages a responsible use of water resources and acts as the global benchmark in this area. We are the first utility in the world to obtain this certification for a drinking water plant and the third largest in Italy. The AWS standard is designed to help companies and individuals implement responsible practices and protect this resource, improving their efficiency and addressing current and future water challenges such as drought, climate change and population growth. It is typically used in the manufacturing sector, adopted by major multinational companies, and is recommended by the United Nations. Obtaining this certification is a rigorous process that includes a range of actions, criteria and indicators on how to manage water, both within the plant and outside of it, across the board, submitting the industry’s best practices to a worldwide scientific committee. A clear path, with no observations, and important benefits in terms of efficiency and water resource protection In the case of the Val di Setta drinking water plant, the certification was completed without any nonconformities. The process is rarely so clear-cut, rewarding our commitment over the past year, the length of the entire process. The efficiency measures implemented in 2020 for managing the drinking water plant led to an overall improvement in the use of resources during the plant’s operations. For example, the filter washing phase was optimized thanks to a priorly conducted study, leading to an overall saving coming to roughly 2,400 cubic meters of water per day in water treatment and purification. The AWS also certifies the degree of efficiency, and the Val di Setta plant is outstanding in this regard: to introduce one litre of drinking water into the aqueduct, it takes 1.1 from the environment, compared to an average amount of 1.7 litres for 1 litre of bottled water. Increased good practices at the heart of the certification This certification is also centred around involving the local community in good practices. The Alliance for Water Stewardship is in fact a global organization created with the main goal of raising public awareness on issues related to water scarcity and the proper use of water. The certification must therefore also indicate that the party in question is committed to communicating the importance of water, promoting its efficient and responsible use in the local area and sharing good management practices with other local figures. The AWS thus aims at creating local and international networks of companies actively involved in managing water resources.

Hera BoD approves results for 1H 2021 Financial highlights Revenues at 4,179.7 million euro (+22.8%) Ebitda at 617.9 million euro (+10.4%) Net profit for Shareholders at 216.1 million euro (+30.0%) Strong improvement in net financial debt, now at 2,956.7 million euro, with a further decrease in the net debt/Ebitda ratio, now at 2.5x Operating highlights Good contribution to growth comes from the Group’s main businesses, in particular the energy and waste areas Progression of results underpinned both by organic growth and M&A Solid customer base in energy sectors, coming to almost 3.4 million customers The Hera Group’s Board of Directors, chaired by Tomaso Tommasi di Vignano, unanimously approved the consolidated operating results for the first half of 2021, which confirm the positive trend shown by the Group, with strong growth in the main operating and financial indicators, and financial solidity confirmed by the further improvement in the net debt/Ebitda ratio, now at 2.5x. Among the main changes in the scope of consolidation, external growth occurred through a few transactions in the waste management sector, in particular the acquisition of 70% of Recycla, a Friuli-based company that manages three platforms for solid and liquid industrial waste and is headquartered in Maniago (PN), consolidated in the first half of 2021. In addition, 31% of SEA, a company operating in the Marche region with a solid facility for industrial waste, was acquired, and a further transaction will be closed in the same area within the summer. Furthermore, another acquisition will contribute to the results in second half: yesterday it was finalised the acquisition of the 90% of share capital of Ecogas, operating in Abruzzo, which will bring roughly 22,000 new customers and will lead the Group to consolidate its role as the third largest operator in that area, with roughly 90,000 customers. Revenues increase sharply, coming to roughly 4.2 billion euro In the first half of 2021, revenues amounted to 4,179.7 million, rising considerably by 777.4 million (+22.8%) compared to the 3,402.3 million seen in the same period of 2020, thanks to the contribution coming from all business areas. In particular, the waste management sector contributed to growth with an increase in waste treated and plastics sold, as did the energy areas. In this area, higher revenues came from trading, higher volumes of gas sold, the increased price of electricity and generation, as well as growth in the heat management business and value-added services. Ebitda rises to 617.9 million euro Ebitda amounted to 617.9 million, up by 58.2 million (+10.4%) over the 559.7 million seen at 30 June 2020. This growth was mainly driven by the energy area, due to higher sales and trading margins, and the waste management sector. Operating results and pre-tax profits increase Operating income rose to 343.6 million (+16.2%), compared to 295.7 million in the same period of 2020, partially due to improved financial operations, coming to 55.1 million. This result includes higher charges resulting from the sale of tax credits as part of ecobonus-related activities. Pre-tax profit rose to 288.5 million (+20.5%), up compared to the 239.5 million in the first half of 2020, for reasons including non-recurring items related to a tax exemptions, as described in further detail below. Net profits for Shareholders up, reaching 216.1 million euro Thanks to a tax rate coming to 26.7%, an improvement compared to the 27% seen in the first half of 2020, achieved thanks to the Group’s commitment investment in technological, digital and environmental transformation following Utility 4.0 trends, net profits at 30 June 2021 rose to 236.2 million (+35.1%), compared to 174.9 million in the first half of 2020. This increase is also linked to the value of special items, which contributed with 24.7 million, also due to the effects of the tax realignment concerning some goodwill recognised in the financial statements for 46.3 million. Also due to this factor, profit attributable to Group Shareholders increased sharply, coming to 216.1 million (+30.0%), as against the 166.2 million seen in the same period one year earlier. Strong increase in investments and improvement in net financial debt Net operating investments went from 195.1 million at 30 June 2020 to 237.4 million in the first half of 2021, up 21.7%, and were mainly related to works on plants, networks and infrastructures, in addition to investments for the large-scale meter replacement and the purification and sewage sector. Thanks to the positive contribution coming from operations, which allowed both higher investments and M&A transactions to be fully financed, net financial debt further improved, settling at 2,956.7 million at 30 June 2021, compared to 3,227.0 million at 31 December 2020. The Group’s financial solidity was also confirmed by the net debt/Ebitda ratio, which in the first half of 2021 dropped to 2.5x, a further improvement compared to 2.87x at the end of 2020 and 2.81x at 30 June 2020. Hera’s financial strength – also reflected in the ratings given by the main rating agencies, including Standard & Poor's recent upgrade to BBB+ with a stable outlook – goes hand in hand with the sustainable development strategy it has pursued since its establishment, along with its ability to manage risks and opportunities, as shown by S&P Global Rating’s ESG Evaluation. Statement by Executive Chairman Tomaso Tommasi di Vignano Our half-year results reflect the good performance of the Group and encourage us to look towards the future with confidence, in line with our long-standing path of growth and our focus on creating value for our shareholders and the local areas in which we operate. In particular, respecting the strategic guidelines contained in our Business Plan to 2024, we are carrying out a series of transactions aimed at external growth, which will allow us to consolidate our leadership in Italy in waste treatment and further expand our plant platform, with cutting-edge facilities and circular economy solutions for companies. In this way, we will be able to continue to extend the scope of our activity, extracting synergies and guaranteeing increasing benefits for our customers, thanks to a more pervasive presence in the areas served. The acquisitions in the waste management area alone, once completed, will create an additional contribution to the Hera Group’s Ebitda coming to approximately 20 million euro, above and beyond the value of the synergies expected from these integrations. Statement by CEO Stefano Venier The results achieved in the first half of the year show a further reinforcement of our financial solidity, based on an excellent operating performance and effective management of working capital. This balanced and solid path allows us to effectively govern the changes underway, guaranteeing further expansion in investments and continuing to implement the development strategy outlined in our Business Plan, capable of combining growth and solutions supporting the transition, as further confirmed quite recently by S&P Global Rating’s ESG Evaluation.

Sede Hera We rank 5th internationally among the Utility Networks assessed by this rating agency’s Sustainable Finance analysts, thanks to our focus on sustainability and our ability to manage risks and opportunities After being included in the Dow Jones Sustainability Index, World and Europe, in 2020, we have once again confirmed our standing as one of the companies most attentive to sustainability and ESG aspects internationally. Hera’s ESG Evaluation, carried out by the Sustainable Finance analysts of S&P Global Ratings, was indeed published. This is a cross-industry assessment of a company’s ability to effectively manage, over the medium and long term, its exposure to environmental, social and governance risks, as well as to seize opportunities arising from the changes occurring in a constantly evolving international context. We are the first company in Italy to publish its ESG Evaluation, in which we obtained an overall score of 81/100, making it one of the top fifteen companies assessed internationally by S&P Global Ratings. The score obtained (81) places us well above the international (68) and European (73) average and ranks us fifth internationally among Utility Networks (with the sector average coming to 74). In particular, in the ESG Evaluation, we are assessed by S&P Global Ratings as being strongly prepared to implement its growth and development strategy, ready to face the potential risks deriving from regulations in an economy that is moving towards the circular model, with low emissions, supporting the resilience of its well-diversified business model.

Herambiente acquires the company Recycla The Hera Group, through its subsidiary Herambiente has acquired 70% of Recycla, a Friuli-based company that manages three platforms for solid and liquid industrial waste, whose central offices are in Maniago (PN). This transaction will confirm Herambiente’s position as a key operator in the sector and allow it to offer its across-the-board waste treatment solutions to new customers. Through its company Hasi (Herambiente Servizi Industriali), Herambiente has thus consolidated and expanded its facilities serving businesses, with 15 multifunctional sites dedicated to the treatment of waste produced by companies and 1.2 million tonnes of industrial waste treated each year. More specifically, the Maniago platform for solid and liquid industrial waste handles over 40,000 tonnes per year of waste produced by companies. In line with the principles of the circular economy, this waste is pre-treated to optimise its characteristics and is mainly destined for energy recovery or chemical-physical treatment. Therefore, only 3% of the waste entering the platform is disposed of in landfills. This transaction, which follows the acquisitions completed in recent years (from Waste Recycling, Teseco and Pistoia Ambiente in Tuscany and Geo Nova and Aliplast in Treviso), is a new step in Herambiente’s continuous growth in the industrial waste treatment sector. This development will be further strengthened by two agreements already signed with companies operating in the Marche and Veneto regions in the same industrial sector, which will be finalised within the summer. When fully operational, thanks to these three transactions, an additional 350,000 tonnes of industrial waste produced by 3,300 new customers will be treated each year.

Top10 2021 We rank first among Italian companies for its full and conscious integration of sustainability policies within its business strategies. This has been confirmed by the 2021 Integrated Governance Index, presented today at the ESG Business Conference, an authoritative model for analysing ESG factors, i.e. the social, environmental and governance aspects of business activities. In addition to leading the overall ranking, we also stand out in two other dedicated rankings. For the fourth year in a row, the Group is at the top of the sustainable finance category, which analyses the links between a company and responsible investors. It also ranked second in the special 2021 ESG Identity survey, which focuses on a company’s ability to enhance its sustainable identity, through means including stakeholder involvement, first and foremost customers and suppliers. Sustainability at the heart of the Group’s strategies For us, uninterrupted growth in operating results goes hand in hand with increasing attention to sustainability. In 2016, we introduced shared value reporting, referring to those business activities which, in addition to generating margins, respond to the drivers for sustainable growth defined by the UN 2030 Agenda and, more generally, various national and international policies. We gave further evidence of the central role played by creating shared value when it introduced the concept of Purpose in our Articles of Association, among the first companies in Italy to do so. Last April, the Shareholders Meeting approved a paragraph explaining the Group’s corporate purpose, i.e. the objectives it aims to achieve in carrying out its business activities, thus reaffirming its commitment to sustainability. The Integrated Governance Index The Integrated Governance Index is the only model for quantitatively analysing degree to which ESG factors are integrated into corporate strategies. Developed by ETicaNews, with the academic and legal support of specialised associations and advisors, it is now in its sixth edition. This index is increasingly used as an indicator of a company’s ESG identity.

Financial results as at 31 March 2021 Financial highlights Revenues at 2,271.8 million euro (+10.5%) Ebitda at 362.0 million euro (+3.7%) Net profit for Shareholders at 132.2 million euro (+6.3%) Net financial debt shows strong improvement, now at 3,077.6 million euro, and net debt/Ebitda ratio falls to 2.71x Operating highlights Good contribution to growth coming from the Group’s main businesses, the energy sectors and waste management in particular Solid energy customer base, now reaching almost 3.4 million Further development in initiatives for the circular economy, with aspects including state of the art plants and increasingly green services for companies and citizens The Hera Group’s Board of Directors, chaired by Tomaso Tommasi di Vignano, unanimously approved the consolidated results for the first quarter of 2021, with all main operating and financial indicators improving, compared to the same period in the previous year, thanks to the Group’s solid, efficient and sustainable multi-business strategy and a good operating, financial and fiscal management. The energy sectors and the waste management area made a particularly important contribution. Also note the additional improvement in financial solidity, with a strong reduction in net financial debt. At 31 March 2021, the number of energy customers reached almost 3.4 million, thanks to factors including marketing initiatives and reinforced value-added services, from “green” offers to the sale and installation of LED devices, smart boilers and thermostats, as well as energy diagnoses, contracts for energy services, systems and targeted upgrading projects. The acquisition in September 2020 of the company Wölmann, which operates in the photovoltaic panel installation sector, is also part of this context and represents the main change in scope of operations compared to the first quarter of the previous year. Revenues reach approximately 2.3 billion (+10.5%) In the first quarter of 2021, revenues amounted to 2,271.8 million, up 10.5% compared to the 2,055.8 million seen in the same period of 2020. This result was sustained in particular by the energy sectors, with higher revenues from trading, higher volumes of gas sold and an increase in the price of electricity, in addition to the heat management business and activities involving value-added services for customers. Revenues from district heating and regulated network services also increased, as did those from the waste management area, thanks to energy production and a higher amount of waste treated. Ebitda rises to 362.0 million (+3.7%) Ebitda rose from 349.2 million in the first quarter of 2020 to 362.0 million at 31 March 2021, showing a 12.8 million (+3.7%) increase. This growth is due in particular to the performance achieved in the energy areas, which grew by 12.3 million overall, mainly due to higher sales margins and trading. Positive contributions also came from the waste management area and other services, while the water cycle saw a slight fall. Operating result and pre-tax profit increase Ebit rose, amounting to 223.1 million at 31 March 2021, up from 211.7 million in the same period of 2020 (+5.4%). Financial operations were largely unchanged, at 28.8 million, with an increase in charges for tax credit sales as part of ecobonus-related activities, offset by higher income for late payment indemnities on credits in the “last resort” markets. Pre-tax profit rose to 194.3 million (+6.2%). Net profit for shareholders grows to 132.2 million (+6.3%) Thanks to an improved tax rate, coming to 27.8% compared to 28.8% in the first quarter of 2020, driven by the Group’s commitment to making investments in technological, digital and environmental transformation with an eye to Utility 4.0, net profit at 31 March 2021 reached 140.3 million, up 7.7% compared to the 130.3 million seen in the same period of 2020. Profit pertaining to Group shareholders also rose to 132.2 million, up 6.3% compared to the 124.4 million seen in the same period of 2020. Operating investments rise and net financial debt improves significantly Net operating investments were up significantly, from 91.5 million at 31 March 2020 to 112.6 million (+23.1%) in the first quarter of 2021, and were mainly related to work on plants, networks and infrastructures, with investments in gas distribution concerning the large-scale meter replacement, and in the purification and sewerage area. Thanks in particular to the positive contribution coming from operational management during the quarter, a strong improvement was also seen in net financial debt, which stood at 3,077.6 million, compared to 3,227.0 million at 31 December 2020, down by approximately 150 million. Thanks to the double leverage provided by increased Ebitda and decreased net financial debt, the net debt/Ebitda ratio further improved to 2.71x, both compared to the same quarter last year (2.93x) and to the figure seen at the end of 2020 (2.87x). This data once again confirms the Group’s financial solidity, which also appears in the opinions released by major rating agencies, in particular the recent upgrade by Standard & Poor’s to BBB+ with a stable outlook.

Sustainability report 2021 Figures allow us to better analyse processes and impacts, to activate improvement actions and to transparently report the results achieved. These are the objectives of our Sustainability Report, published online and focused on the year 2020 just ended. A document that represents the value horizon we operate in and that aims to combine industrial growth and sustainable development while striking a balance between three dimensions represented by as many keywords: planet, people and prosperity. Creating value together with the communities served: over two billion EUR distributed locally Sustainable growth also involves the economic and social fabric of the territories served. Here are some figures: the economic value distributed to workers, shareholders, suppliers, public administration and local community in 2020 was 2,118 million, of which 740 million to local suppliers (+6% compared to the previous year, 65% of the total value of supplies), generating an employment impact of over 8,800 workers and allowing the inclusion of 864 disadvantaged people through social cooperatives; 584 people were hired during the year and 96.6% of employees have permanent contracts. The gross operating margin (EBITDA) from our activities that address the priorities of the Global Agenda, in particular the sustainable development objectives of the United Nations, rose to 420 million EUR in 2020, 37% of the total (it will be 50% in 2024), divided into three areas: energy, environment, territory (and business). Energy: pursuing carbon neutrality Working on energy for us means first and foremost pursuing carbon neutrality, with actions that involve both the company and all social players, in the interest of a planet that is increasingly exposed to climate change and whose natural resources are compromised. An example is the goal of reducing greenhouse gas emissions that we set ourselves, among the most ambitious for a company in Italy: 37% less by 2030 compared to 2019, validated according to the strictest scientific criteria by the prestigious international network Science Based Target initiative (SBTi). Overall, the actions we have taken range from promoting energy efficiency to energy transition and renewables. Internally, in 2020 energy consumption fell by 6.2% over 2013 (equal to 13,800 tons of oil equivalent) and 83% of the electricity used is derived from renewable sources. In addition, 7.8 million cubic metres of biomethane were produced through the transformation of organic waste in the plant in S. Agata Bolognese (Bo), 20% more than the previous year. Through the construction of new plants, the goal is to produce up to over 30 million cubic meters in 2030. As far as customer involvement is concerned, also in 2020 we purchased electricity from renewable sources in such a quantity as to fully cover the consumption of all household customers in the free market, and in 2030 we aim to reach 45% of subscriptions to offers that include energy efficiency services, thus supporting them in adopting virtuous behaviours with 100% green offers and consumption containment tools.

President_and_CEO_110 Hera’s Ordinary and Extraordinary Shareholders Meeting was held this morning in Bologna. The 2020 financial statements were approved, as was payment of a dividend rising to 11 cents per share (+10% compared to the last dividend paid), providing further confirmation of value creation for stakeholders and local areas. Among the various resolutions passed, the Meeting approved a number of amendments to the company’s Articles of Association, in particular introducing the concept of corporate purpose. The 2020 Sustainability Report was also presented at the Meeting. Approval of the 2020 financial statements and growth in results During the ordinary session, the Shareholders Meeting approved the 2020 financial statements, which showed improvement in the main operating and financial indicators, thanks to a solid, efficient and sustainable multi-business model and good operational, financial and fiscal management. Despite the health emergency that struck the world, Hera managed to close the year positively, guaranteeing quality and continuity in services and, at the same time, protecting its stakeholders with concrete actions, first and foremost employees, customers and suppliers. Dividend increasing to 11 cents per share approved The Shareholders Meeting then approved the Board of Directors’ proposal to pay a dividend coming to 11 cents per share, up 10% over the last dividend paid and higher than the amount foreseen by the Business Plan for the current year. The coupon date has been set at 5 July 2021, with payment starting on 7 July 2021. The Sustainability Report: shared value Ebitda rises to 420.0 million euro The Sustainability 2020 Report was also presented during the Shareholders Meeting, showing how improvement in operating and financial indicators goes hand in hand with the creation of shared value and positive effects for local areas, in the interest of the communities served. In 2020, shared value Ebitda – i.e., results from business activities that, in addition to generating margins, meet the goals for sustainable growth defined by the UN Agenda and, more generally, national and international policies – rose to € 420.0 million euro (+7.2%), equivalent to 37.4% of total Ebitda. Creating shared value now part of the Articles of Association Another important step approved by the Shareholders Meeting concerns the introduction into the Articles of Association of Hera, one of the first companies in Italy to do so, of the concept of “Purpose”, with a focus on creating shared value. In particular, an additional paragraph was included in Article 3 to explain the Group’s corporate purpose, i.e. the goals it aims to achieve in carrying out its business activities. This emphasises Hera’s commitment to sustainability, which has characterized it since its establishment.

SBTi 2021 We can now boast one of the most ambitious targets for reducing greenhouse gas emissions certified on a scientific basis for a company in Italy: down 37% by 2030 compared to 2019. This has been certified by the prestigious international network Science Based Targets initiative (SBTi), born out of a collaboration between CDP, the United Nations Global Compact, the World Resources Institute and the WWF, which today – World Earth Day – formalized its validation of our greenhouse gas reduction targets. We are committed in particular to the “Well below 2°C” goal, aimed at limiting the increase in global temperature to considerably below 2°C compared to pre-industrial levels, in line with the path set out by the Paris Climate Agreement. At the forefront in the energy transition and the fight against climate change Our focus on sustainability is fully integrated in the business strategies and goes hand in hand with creation of increasing shared value, with stakeholders and the areas in which we operate. We have long been at the forefront in the fight against climate change, taking action and making investments for the energy transition towards carbon neutrality and the transition to a circular economy, as reiterated in the 2024 Business Plan. And in order to focus our objectives even more concretely, we extend our outlook to 2030, also including the targets validated by SBTi, following the most rigorous scientific criteria. Our objective of a 37% reduction in carbon dioxide emissions is all the more ambitious considering that it is not limited to the emissions produced by the Group’s own activities but also covers those of our customers, in electricity and gas sales, and our suppliers. In fact, we have introduced numerous solutions for individuals and companies to promote energy efficiency, accompanied by broader initiatives intended to increase involvement and awareness, aimed at encouraging reduced consumption. img_canvas_interna.jpg Our objective in reducing greenhouse gas emissions is among the most ambitious for an Italian company, as officially communicated today, World Earth Day, by the international network Science Based Targets initiative /-/hera-to-reduce-emissions-by-37-within-2030 /documents/1514726/4185885/HERA-ITA-002-OFF+Certificate.pdf/58bf5219-2e44-4571-fc1d-4db76a3d7d0c?t=1619018057136 https://sciencebasedtargets.org/ https://eng.gruppohera.it/group_eng/sustainability/sustainability-report Press release read the SBTi certificate Visit SBTi website Read the chapter of the sustainability report dedicated to climate change mitigation centrata SBTi 2021

Tomaso Tommasi di Vignano e Stefano Venier The Hera Group closed the 2020 financial year positively, as well as in all quarters, even during a particularly difficult year on account of the Coronavirus emergency. The Group’s Board of Directors unanimously approved the consolidated economic results along with the Sustainability report. Thanks to its solid and efficient multi-business model, and good operating, financial and fiscal management, Hera succeeded in maintaining growth in its results while at the same time supporting its stakeholders. Even during the lockdown, indeed, Hera guaranteed continuity, safety, quality and efficiency in all services and also provided help not only for its own employees but also its customers, suppliers and local communities. This consisted first in allowing customers to pay with delays or by instalments and offering reverse factoring to small and medium businesses, and later participating in specific solidarity initiatives across the areas served. These initiatives were appreciated by customers, as appears in the recent customer satisfaction poll which, despite the difficult external context, confirmed a high customer satisfaction rate (73/100), with approval of the management and services provided during the emergency coming to 85/100. The Hera Group succeeded in continuing along the path of uninterrupted growth seen since its establishment in 2002, once again leveraging its own strategy: a balanced mix of internal and external growth, with significant economies of scale and higher synergies than expected. All of this while continuously striving to create value for its stakeholders, respecting the directions set out by the new Business Plan to 2024, which aims at accompanying all areas served in a recovery that respects European strategies and the goals on the UN’s 2030 Agenda. “These results indeed reflect our uninterrupted activities, in spite of the pandemic, supporting the economic fabric in which we operate. Quarter after quarter, we succeeded in meeting the challenges posed by the emergency, reacting quickly to reorganise our work and find solutions to protect our assets on the one hand, and customers on the other. In a complex context, we defined new projects and signed agreements with outstanding partners, and in the second half of 2020, gaining speed in particular towards the end of the year, we benefitted from the overall recovery seen in economic activities in the areas we serve. These positive results were reflected in all main indicators and are all the more significant in light of the difficulties caused by the health emergency: we thus confirmed our track record of 18 years of growth and further improved our financial solidity, with positive consequences for our public and private shareholders, to whom we have decided to pay, already this year, an increased dividend coming to 11 cents per share”. Executive President, Tomaso Tommasi, di Vignano went on to say at the end of the Board of Directors meeting of 24 March. Chief Executive Officer, Stefano Venier, added: “The growth achieved by the Hera Group was strongly supported by its partnership with Ascopiave, which enabled the Group to expand further in the Triveneto region. Despite the complex context, we were able to immediately extract a significant part of the expected synergies, thus giving a crucial contribution to the increase in our cash flows in 2020. The year was also dedicated to further progress in fully integrating sustainability into our business strategies: we are committed to promoting further development in this direction, with projects for circularity, carbon neutrality and technological innovation, respecting European policies and the goals on the UN’s 2030 Agenda. This also includes a few collaborations recently launched, such as the one with Snam for developing hydrogen”. 2019-07-18 News_BS_870px_eng.jpg The year ended positively, despite the nationwide impact coming from the Coronavirus emergency, during which Hera stood by its stakeholders and provided support. Thanks to its solid, efficient and sustainable multi-business strategy, Hera thus continued to grow and create value for shareholders and local communities /group_eng/investor-relations/results-and-presentations/y2020 https://eng.gruppohera.it/group_eng/sustainability/sustainability-report/sr /-/hera-bod-approves-y2020-results /documents/1514726/7351398/Bilancio+di+sostenibilit%C3%A0+2020+Highlight.pdf/773fb31e-68a1-a8b4-b487-435b139c741b?t=1618991300290 /group_eng/investors See the interactive 2020 annual report See the sustainability report 2020 Read the press release on Y2020 results 2020 Sustainability Report Highlights Find out the Investor Relations area Tomaso Tommasi di Vignano e Stefano Venier

World Water Day World Water Day celebrates water and raises awareness. On World Water Day 2021, dedicated to the theme 'The role of water in our society and how to defend it’, we renew our commitment to encouraging the responsible use of water. Protecting water and reducing consumption have always been of paramount importance for us, and the service we manage, according to a circular economy approach, has specific and challenging goals. Investments of more than 1 Billion Euro have been allocated to the Water Cycle in the 2024 Business Plan Our strategies to ensure quality, efficiency and resilience require major investments, in order to upgrade infrastructures, even with the use of innovative technologies. That is why, we have allocated investments of over 1 billion Euro to the water cycle in our 2024 Business Plan. Many projects are planned such as the partitioning of the networks into districts, strengthening interconnections, to reduce water loss and guarantee water supplies even in critical situations, as well as water reuse projects. Reducing consumption and efficient use of water One of the goals of the 2030 UN Agenda for Sustainable Development is to substantially increase water-use efficiency across all sectors within 2030. We have set our internal water saving goal by 2030 as 25%, and have already reduced consumption by 5% in 2019 (with respect to consumption in 2017). Monitoring consumption to promote a conscious use of water We have provided numerous free tools to our customers to make them aware of the properties of the water they use every day. The water bill, for example, shows the water label with details (territory by territory) of the main benchmarks. This data is also provided by the report “In Good Waters”, which is published online, and contains, amongst other things, information about the quality of the water managed, which is monitored with almost 3,000 tests a day. The Acquologo (the Water Expert), on the other hand, is a free App for tablets and smartphones that is yet another communications channel with the citizens we serve. Its functions include self-reading of your own water meter or access to data about the water quality in your municipality. The App, which in 2020 alone was downloaded almost 12,000 times, sends warnings to users about the interruption to the water supply for routine maintenance and water leakages or burst pipes on land in the public domain. Our website also has a web area dedicated to water (eng.gruppohera.it/acqua), with useful information and insights. Finally, to encourage a conscious use of water, we were the first to create in Italy, a free tool called, the Consumption Diary, in which users may monitor their water consumption in order to modify the way they use water, giving a saving on water bills while ensuring positive impact on the environment. The project, in collaboration with Milan Polytechnic University, has to date involved over 145,000 domestic users and will gradually be extended to all customers who provide an email address to the company. World Water Day Sede Hera 2013-08-28 For further information World Water Day On World Water Day 2021, we renew our commitment to protecting this precious natural resource. Investments of over one billion Euro have been allocated to the water cycle in our 2024 Business Plan. Our priorities are an efficient use of water and reducing consumption. World Water Day
