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.
