Press Releases and Notices

2022-05-05 Hera continues to create shared value by focusing on the principles underlying a “fair transition” and is able to support the communities it serves in achieving sustainable development. For the first time, the Sustainability Report also provides information on activities consistent with the EU taxonomy Setting challenging goals, growing and innovating by creating value for stakeholders and reporting the results achieved in a clear and transparent way: all of this has always guided Hera’s actions. It also includes protecting the environment and promoting sustainable development, and the Group has summarised it in its 2021 Sustainability Report, now available online (http://bs.gruppohera.it). Industrial growth and sustainable development, therefore, go hand in hand, nourishing one another. In full harmony with Brussels and the main international policies, Hera continues to take determined steps towards bringing about a “fair transition”. This model puts people at its centre and translates into a gradual process, planned so as not to leave anyone behind. On the contrary, it is designed to accompany the local areas served towards a more environmentally sustainable future, and also one that can concretely be achieved from an economic and social point of view. One of the most important new features of the 2021 Sustainability Report is the information provided for the first time concerning activities consistent with the European Union’s taxonomy, with particular reference to the objectives of mitigating and adapting to climate change, thus anticipating regulatory obligations that will only come into force in 2023. Creating value together with the communities served: more than 2.2 billion euro distributed to local areas The Group’s sustainable growth also involves the surrounding economic and social fabric, as is proven by the over 2.2 billion euro distributed in 2021 to the areas served. Hera guarantees them continuity and efficiency in its services, with significant investments made in innovating the infrastructure assets that will be decisive in facing the climate-related challenges of the coming years. Moreover, the total economic value for stakeholders rose to over 2.9 billion euro, including workers (592.8 million), shareholders (217.9 million), public administrations (115.1 million), and approximately 1.2 billion relating to suppliers. Shared value Ebitda rises to 570.6 million One of the most important results reported is shared value Ebitda, referring to business activities that also respond to the drivers of sustainable growth. This figure rose to 570.6 million, a significant increase over 2020 (+25.4%), corresponding to 46.6% of total Ebitda. This is a sign that the positive economic results achieved are accompanied by Hera’s increasing focus on sustainability, a result in line with the trajectory marked out by the Business Plan, which projects this value at 55.6% of total Ebitda by 2025, rising to 70% in 2030. Three main drivers guide this commitment: pursuing carbon neutrality, regenerating resources and closing the loop, and enabling resilience and innovation. Pursuing carbon neutrality For Hera, working on energy means first and foremost pursuing carbon neutrality. Overall, the actions taken by the Group move towards the energy transition and promote energy efficiency. Given that the concentration of greenhouse gases, largely caused by fossil fuels, continues to have a negative impact on the increase in the planet’s temperature, in the field of energy transition and renewable energy the Hera Group continues its commitment to producing increasingly sustainable energy sources. One particularly successful initiative is the S. Agata Bolognese plant, which in 2021 produced 8 million cubic metres of biomethane by transforming the organic waste derived from sorted waste collection coming from citizens, 22% more than in 2019. The goal, to be reached by developing new projects including one in the Modena area thanks to a partnership with the Cremonini Group, is to double the production of biomethane, reaching 16.8 million cubic metres per year in 2025. The relevance of the second area, energy efficiency, must also be considered in relation to the complex international scenarios for the supply and cost of energy, and the role that renewables will play in the sustainable future. The policy to increase the energy efficiency of Hera’s activities will continue, as is borne out by the ISO 50001 certification on energy management obtained for 11 Group companies, where 96% of the entire company’s energy consumption takes place. The Hera Group also supplies renewable electricity to all residential customers on the free market, and when considering all types of customers (residential and non-residential) the total renewable electricity sold on the free market rises from 33% to 40%. Finally, the Group is committed to improving the energy efficiency of condominiums, companies and public administrations, reaching important results, with savings of up to 20-40% of consumption. Regenerating resources and closing the loop No less challenging is the issue of the environment, a front on which Hera is working to regenerate natural resources and closing the loop to promote a more effective use of them. In concrete terms, this means going beyond a linear model to achieve the circular economy. This is the case with municipal waste management: in the areas served by the Group, the EU objective of a 55% waste recycling rate by 2025 has already been achieved, as has the 73% recycling rate for packaging (higher than the EU objective for 2030). This result is due to another important fact: the average sorted waste collection rate comes to 65.3%, higher than the national average for the sector. Moreover, among the 10 most virtuous Italian cities with more than 100,000 inhabitants, as regards sorted waste collection per capita, 4 are managed by Hera, with Ferrara leading the national ranking in terms of percentage of sorted waste collection. And waste is not the only factor involved. Closing the loop is a rationale that is applied across the board, such as in the sustainable management of water resources. Here, we’re talking about 414 million cubic metres supplied down to the last cubic metre, of the highest quality. To make this possible, one must have an excellent set of plants. One example is the Val di Setta drinking water plant, in Bologna area, which has obtained AWS (Alliance for Water Stewardship) certification, an acknowledgement received by Hera as the world’s leading multi-utility. But attention and protection occur first and foremost from within the Group, which in 2021, for example, achieved a reduction of approximately 17% in its internal water consumption, compared to 2017. Enabling resilience and innovation Hera operates locally to enable resilience and innovate, following a rationale of adaptation aimed at guaranteeing, among other things, continuity in services and the availability of resources, by extending infrastructures in the areas served through smart plants and networks. In this context, in line with international policies, digitisation and innovation in activities plays a key role, supported by an investment of 82 million euros in 2021 alone, with projects that involve not only the Group but also the local communities, helping them move towards the digital transition. Making communities more resilient also means working to promote social inclusion. For this reason, in 2021, almost 200,000 bills were paid in instalments, for a total value of 126.8 million euro. In February 2022, in order to consider the situation ensuing from the increase in commodity prices, Hera signed an agreement with consumer associations, in addition to national regulations, to go even further in helping customers in difficulty. 20220505_PR Sustainability report 2021.pdf 11:07:00 See the press release

2022-02-24 On the occasion of the tenth edition of this award, reserved for public utility companies, Hera received the first prize overall among the companies analysed, awarded today during an event dedicated to digitalisation Top Utility According to Top Utility, the Hera Group is the leading Italian utility in terms of economic and financial policies, sustainability, research and innovation, communication and the positive effects on the areas served. This prize has been assigned over the last ten years following an analysis of the main companies in the water, energy and waste management sectors, carried out by a research team from Althesys, a consultancy firm specialising in the public utility sector. The award ceremony was held during an online event entitled “Digitalization and sustainability for the future of Italian utilities”. The Hera Group’s best practices rewarded over the 10 years of Top Utility In particular, this year the Hera Group was awarded the overall Top Utility prize for the following reasons: “For the excellent results achieved in all areas analysed, with particular reference going to stakeholder relations, transparency and communication. Hera has also confirmed itself at the forefront in digitalising business processes and in the sustainability of operations”. This is the second time that Hera has received this important award, an even more significant achievement since this marks the twentieth anniversary of the Group’s establishment, which occurred in 2002 when 11 municipal companies in the Emilia-Romagna region merged. Today, Hera is the first operator nationwide in the waste management area, second in the integrated water cycle and third in electricity and gas sales. Over this award’s history, Hera’s efficiency and good practices have been abundantly confirmed: in addition to receiving the overall Top Utility in 2012, in 2014 and 2019 it received a prize in the communication and transparency category, in 2015 and 2018 in the sustainability category, and in 2021 in the gender equality and diversity and inclusion category. Looking to the future: a focus on generating shared value These two anniversaries are important in conceiving the future of this sector, examining the growth and evolution that municipal utilities have undergone to date and the strong impact they have had on local communities. In this sense, the core of the Hera Group’s strategy and identity consists in uninterrupted economic growth accompanied by sustainable development of its businesses and the areas served. Its commitment to generating shared value has indeed been confirmed as the cornerstone of its relations with all the stakeholders with whom Hera interacts, starting from its own employees and including institutions, local communities, customers, shareholders, citizens and suppliers.

2022-01-27 The new five-year strategic document builds on the Group’s path of growth, with investments coming to over 3.8 billion and concrete energy transition and circular economy projects. The Plan is solidly based on twenty years of experience, with positive value creation for shareholders, local areas and the communities served, and on the results for the 2021 financial year, whose Ebitda is estimated at over 1.2 billion euro Sede Hera Operating-financial highlights 2025 Ebitda: 1.4 billion euro (+277 million compared to 2020) Total industrial and financial investments: over 3.8 billion Net debt/Ebitda at 2.8x in 2025 Further increase in dividends, reaching 14.5 cents per share in 2025 (+32% compared to the last dividend paid) All five-year operating and ESG targets revised upwards Industrial highlights Confirmation of strategy focused on 3 areas: environment, socio-economic factors and innovation, with a wide range of concrete projects in all business areas Development driven by both internal and external growth (M&As) and balanced between regulated and free-market activities Goal of 4.5 million energy customers by 2025 Shared value at 780 million euro by 2025 (roughly 55% of total Ebitda) Among the objectives for 2030: reducing CO2 emissions by 37% and increasing recycled plastic by 150% A Plan that combines growth, value creation and sustainable development Today, the Hera Group’s Board of Directors, chaired by Tomaso Tommasi di Vignano, approved the Business Plan to 2025, which consolidates the Group’s commitment to balanced and sustainable development in all business areas, with the aim of continuing to create value for shareholders, local areas and the communities served. With Ebitda expected to reach 1.4 billion in 2025 and investments totalling approximately 3.8 billion over the period covered by the Plan, this five-year strategic document shows increases in all main targets and outlines a wide range of actions for the energy transition, the circular economy and technological evolution, with concrete and innovative projects that will also benefit from funding opportunities coming from the Recovery and Resilience Plan. 20 years of uninterrupted growth, and 2021 Ebitda expected to total over 1.2 billion euro The new Plan is based on a trend of uninterrupted growth, as is proven by Group Ebitda, which has increased more than sixfold in 20 years. This consistent and linear path has been seen since the establishment of the Hera Group, which is characterised by a full correspondence between the commitments made and the initiatives implemented, capital and financial solidity and a multi-business strategy that balances regulated and free market activities, internal growth and M&A transactions. This model, which has proved its resilience and capability of supporting stakeholders, even during adverse scenarios, has enabled the Hera Group to consolidate leading positions in all business areas. Projections for 2021 year-end results are also positive, exceeding expectations, with a preliminary Ebitda rising to over 1,220 million euro, compared to 1,123 million at the end of 2020, and a net debt/Ebitda ratio coming to approximately 2.7x, an improvement on 31 December 2020. Last year, in addition to increased dividends, significant investments were seen, amounting to over 650 million euro, with strong growth over 2020. A recovering macroeconomic scenario, with coordinated actions for a fair and sustainable transition After the slowdown seen in 2020 due to the health emergency, global trends are now positive, with the European and Italian economies returning to rapid growth. This recovery, moreover, is generating tension in some sectors, such as raw materials, causing a significant increase in market volatility, which is set to continue in the coming months, and which will see the Group further strengthen both its risk management strategies and its actions to support stakeholders. In this framework, European and national institutions are implementing coordinated and convergent actions aimed at a fair, sustainable and inclusive transition. In particular, with its Recovery and Resilience Plan, Italy has entered the executive phase of the Green Deal, with funds supporting carbon neutrality interventions and regenerative and circular development models. The opportunities seen in the Italian context also include those related to the consolidation of markets that are still overly fragmented, tenders for the renewal of services under concession, and the further liberalisation of electricity sales, with the elimination of protected markets. Three focal points of the Business Plan to 2025: environment, socio-economic factors and innovation In a context undergoing recovery, with an increasing emphasis on sustainability and the utilities sector set to benefit from the most significant share of the Recovery and Resilience Plan, the Hera Group will be able to continue to leverage the competitive position it has cultivated over the years and thus grow. In full compliance with national and European policies and the objectives on the UN’s 2030 Agenda, which have been guiding Hera’s strategies for some time, all projects in the Business Plan to 2025 are structured around three focal points: the environment, socio-economic factors and innovation, with initiatives for the green and digital transition, capable of generating positive effects in the areas served. The environmental focal points include initiatives to combat climate change, in order to achieve carbon neutrality, with actions to reduce emissions, increase infrastructure resilience and promote the circular economy. The socio-economic aspects, on the other hand, aim to create “shared value”: under the Plan, the Hera Group will extend the range and quality of its services in areas where it has been present for quite some time, reinforced by the newly awarded tenders for regulated service concession renewals, and in new areas as well, and will seize further development opportunities through external growth. Lastly, innovation will embrace all opportunities linked to technological evolution, with the aim of further increasing the efficiency and quality of services, and above all introducing changes in its model of organisational management. A strong increase in investments, coming to over 3.8 billion euro, thanks to the Group’s financial solidity The Plan to 2025 calls for a sharp increase in investments, amounting to more than 3.8 billion euro, or approximately 770 million per year. This is a very significant rise – equivalent to 60% – compared to the average seen over the last five years, and is possible thanks to its solid financial structure, reinforced over the years and in 2021 as well. Investment allocation combines internal development opportunities with actions to increase system resilience (accounting for roughly 1.2 billion). Significant investments for innovation will be made in all business areas and support will be given to the ongoing transition. In general, of the total investments envisaged in the Plan, more than 1.7 billion are aligned with the criteria with which the European Taxonomy identifies opportunities that contribute to environmental policy objectives, in particular the two areas regulated for now, relating to mitigation of and adaptation to climate change. Furthermore, many of these interventions respect the directions indicated by the Recovery and Resilience Plan. Thanks to an optimisation of financial and fiscal costs, the Plan outlines an increasing creation of value, as seen among other factors by ROE and ROI, projected at 10.6% and 8.7% respectively in 2025, a particularly appreciable result considering that the recent reduction in WACC for regulated activities concerns 60% of the invested capital. Moreover, the net debt to Ebitda ratio at 2025 is expected to be 2.8x, consistent with the current figure and indicative of a strong self-financing capability, providing room for manoeuvre that will allow the Group to take advantage of any additional unforeseen opportunities that may arise during the period covered by the Plan. Ebitda expected to rise to 1.4 billion by 2025, thanks to both internal and external growth The improved scenario and the increase in investments have enabled the Hera Group to revise all its five-year targets upwards, first and foremost Ebitda, which is expected to reach 1.4 billion euro in 2025, 277 million more than the 1,123 million seen at the end of 2020. The average annual increase comes to 4.5%, higher than the 3.7% forecast by the previous Plan (this data already includes the impact of the reduction in tariffs following Arera’s WACC revision for regulated activities included in gas, electricity and water bills). Besides the positive contribution coming from all business sectors, internal growth and operating efficiencies will contribute 192 million euro to Ebitda, while 100 million will come from new M&As, plus any synergies that the Group will be able to extract, in line with its previous trends. A further 22 million in Ebitda will be generated by the operations concluded in late 2020 and early 2021: the acquisition of the company Wölmann, which operates in photovoltaic panel installation, the energy sales company Ecogas and three companies in the industrial waste sector: Recycla, Gruppo Vallortigara and SEA. Synergies, efficiency gains, expansion of market shares, new projects and investments will thus make it possible to offset the negative impacts, totalling 37 million, deriving from the loss of some incentives, such as those on the production of renewable energy, and the cut in the WACC on regulated services mentioned above. Sustainability as a strategic priority: “shared value” Ebitda at 55% in 2025, almost 70% in 2030 Sustainability remains one of the cornerstones of the Group’s strategies for growth, perfectly integrated and relevant to all operating areas, with an increasing focus on creating value for stakeholders, as shown by the recent introduction of the concept of corporate purpose in the Group’s Articles of Association. “Shared value” Ebitda itself, reported since 2016 and referring to business activities that meet the sustainability goals on the UN Agenda, has increased steadily over the years. It is expected to reach roughly 55% of total Ebitda in 2025, equivalent to 780 million euro, and to amount 70% in 2030, along a linear path that generates concrete benefits for the areas and communities served, proportionately reflecting the company’s own development. The Hera Group’s best practices in ESG areas, in any case, have long been recognised both nationally and internationally. Along with ranking first in the 2021 Integrated Governance Index, which measures the integration of sustainability into corporate strategies, Hera has been included, as leader in its sector (Multi-Utility & Water), for the second year in a row, in the Dow Jones Sustainability Index, World and Europe, one of the most authoritative stock exchange indices in the world assessing social responsibility. Further increase in dividends, rising to 14.5 cents per share As confirmation of its focus on generating value for shareholders, the Group plans to pay steadily increasing dividends: upon approval of the 2021 Financial Statements, the Group will in fact propose to the Board of Directors a 12 €cents/share dividend, compared to 11 €cents/share for the 2020 dividend, thus showing an increase of 1 €cent instead of 0.5 €cents, as initially planned. This additional increase will thus benefit all prospected dividends, which will reach 14.5 €cents/share in 2025 (32% more than the last dividend paid). This higher dividend payment is in line with the expected trend in earnings per share, which will also rise by 5.7% per year on average until 2025. The networks sector: resilience, resource regeneration and development of “clean energy” solutions Ebitda expected in 2025 from the networks sector – which includes electricity and gas distribution services, the water cycle and district heating – comes to 533 million euro, up 73 million compared to 2020. This target is all the more significant considering that it fully offsets the revised WACC, effective as of 1 January 2022, which will have a -22 million impact over the period covered by the Plan. Most of the internal growth will come from two main drivers: infrastructure development, with investments bringing overall RAB to 4 billion euro, and further cost efficiency coming to 40 million euro, made possible among other things by an increased use of digitalisation and innovations on infrastructures that introduce new operating models. More specifically, Hera will invest approximately 2.1 billion euro in extending, modernising and evolving its networks, focusing on integrating traditional methods with technologically innovative solutions to ensure resilience, efficiency and business continuity even in the event of extreme weather events. Interventions for the smart transition include installing approximately 420,000 second generation (2G) electricity meters that will measure consumption more precisely. As regards gas distribution, in addition to replacing gas meters in compliance with regulatory obligations, installation of “NexMeter” devices will continue, patented by the Group and equipped with advanced safety functions in the event of leaks or earthquakes, and cutting-edge technology in terms of reducing gas dispersion into the atmosphere. By 2025, 300,000 will be installed, 200,000 of which in the new recycled plastic version and ready to measure blends with “green gas”. This green version of NexMeter will be at the centre of the first trial in Italy concerning the use of gas and hydrogen mixtures in household gas distribution, in the Modena area. Hera’s multi-business competence, indeed, represents a strategic opportunity to develop solutions in the field of “clean energies”, as shown by the project for a unit with power-to-gas technology at the Bologna Corticella purification plant, already at an advanced planning stage, with start-up expected by 2023. As regards tenders for gas distribution, Hera aims to confirm its position as service manager in the areas already covered, with two more tenders expected over the period covered by the Plan, in addition to ATEM Udine 2, which the Group was recently awarded. In district heating, Hera’s goals include increasing volumes distributed and developing the heat generation mix, with the goal of reaching 77% of energy from renewable and assimilated sources in the networks managed by the Group within 2025. Lastly, in the water cycle, Hera will aim for an increasingly efficient use of water resources, with a reduction in consumption and circularity solutions, and will invest in new technologies to increase network efficiency and resilience, through means including enhanced automation and remote monitoring. The energy sector: 4.5 million customers by 2025 and focus on value-added services and energy efficiency By 2025, Ebitda in the energy sector will amount to 444 million euro, up 76 million compared to the 368 million seen in 2020, while the investments made during the period covered by the Plan period will come to approximately 550 million euro. Hera will continue its efforts to expand the customer base, with the aim of consolidating its position as the third largest operator in the energy sector in Italy and reaching 4.5 million customers by 2025, due to factors including upcoming competitive procedures for eliminating protected markets. This will be due to significant investments in customer experience, to improve its effectiveness and efficiency, introducing new functions and tools to encourage customer involvement and interaction with the company, while maintaining the “cost to serve” per client stable over the years. Ebitda will be sustained first and foremost by extracting commercial expansion and cross-selling activities – amounting to approximately 27 million – due in particular to the integration of EstEnergy, the internal growth created by sales campaigns and the increased amount of value-added services and energy efficiency, continuing also to take advantage of all the opportunities related to the so-called super-ecobonus. The range of value-added services, in particular, will be further expanded with solutions for reducing consumption and new integrated proposals for protecting the environment, such as photovoltaics. This focus on sustainability is confirmed by the fact that proposals are already made to all retail customers for 100% energy from renewable sources. Hera will also continue to invest in developing electric mobility, with the aim of installing more than 4,000 recharging points by 2025, integrating its offer with a series of advanced products and services. Lastly, as regards external growth, following up on the acquisitions already completed, the Group will aim to acquire new customer packages in a market that is still highly fragmented and in which smaller operators, vulnerable due to the currently high volatility of energy markets, are disappearing. A leader in waste management, with outstanding plants and innovative projects for the circular economy Ebitda for the waste management sector will also rise, going from 258 million euro in 2020 to 380 million in 2025, with investments expected to amount to almost 1.1 billion over the period covered by the Plan. In this sector, the Hera Group is the leading operator nationally, with a set of approximately ninety state-of-the-art facilities in line with European best practices, capable of treating all types of waste. Under the Plan, the Group aims to consolidate its leadership through new acquisitions, commercial development, growth in volumes treated, increased recovery and recycling activities. It will thus meet the rapidly growing demand and continue to implement projects in support of the circular economy. Group subsidiary Aliplast, already a leader in plastics recycling, will play a central role in promoting the circular economy, extending its efforts by increasing the capacity of plants dedicated to treating flexible plastics (PET and LDPE). Thanks to its partnership with NextChem, part of the Maire Tecnimont Group, it will also enter the rigid plastics segment, with the construction in Modena of an innovative plant producing high-quality recycled polymers, which will promote the sustainability of certain sectors, such as IT and consumer electronics, which until now have only been able to use virgin plastics for their products. A new plant is also being planned to recycle carbon fibre, which can then be reused to make new products, particularly in the automotive sector. In general, the objective is to increase the volume of recycled plastic by 125% in 2025 compared to 2017. In addition, Hera plans to double its production of biomethane – reaching 16.8 million cubic metres per year in 2025 – by replicating the positive experience of the Sant’Agata Bolognese plant in Bologna area, which produces compost and biomethane from organic waste, fuelling sustainable mobility. Through the NewCo Biorg, born out of a partnership with the Cremonini Group, a plant in Spilamberto in Modena area will be restructured to produce biomethane and compost from organic waste and agro-food waste, while in the Marche region Hera is continuing to work on an anaerobic biodigester from organic waste, generating positive effects in an area currently lacking in facilities of this type. Thanks to its unique offer of sustainable and integrated solutions, Hera also aims to expand its industrial customer base. The synergies between the Group’s companies make it possible to offer businesses customised “turnkey” service packages that include all activities relating to the waste cycle, water resources and energy services. A further contribution to enriching Group’s proposals and its geographical coverage will come from recent M&As in industrial waste treatment: in 2021, in fact, Hera acquired 70% of the Friuli-based company Recycla, 31% of Sea in the Marche region and 80% of the Vallortigara Group located in Veneto. Lastly, as regards municipal waste services, the Group has already won tenders in the Ravenna-Cesena, Modena and Bologna areas and aims to confirm its management of this service in the remaining areas already covered in Emilia-Romagna. In these areas, Hera intends to further improve the percentage of sorted waste collected, reaching 76% by 2025, with measures to increase its quality as well, such as involving citizens and businesses with dedicated initiatives and communication campaigns, and installing around 62 thousand “Smarty” computerised bins, automated and remotely controlled, during the period covered by the Plan. The main industrial objectives to 2025, with an eye on 2030 as well The Group’s commitment towards the content of the Plan to 2025 translates into industrial objectives consistent with European policies and UN recommendations. Moreover, in order to define its contribution even more precisely, Hera has extended its perspective to include a series of targets to 2030. One of the most important of these goals is to work towards carbon neutrality. Hera has set itself one of the most ambitious greenhouse gas emission reduction targets for a company in Italy: 37% by 2030, after achieving 26% in 2025 (in both cases compared to 2019). This target – validated by the prestigious international network Science Based Target initiative – is even more significant since it takes into account both the Group’s activities and those of its suppliers and customers in electricity and gas sales. The Group has also confirmed its commitment to the circular economy and regenerating resources. Some targets include: increasing the percentage of packaging recycling, from 73% in 2020 to 76% in 2025 and over 80% in 2030, and increasing the percentage of wastewater reused, from 5.1% in 2020 to 8.5% in 2025 and 15% in 2030. Tomaso Tommasi di Vignano, Executive Chairman of the Hera Group The Hera Group’s Business Plan to 2025 outlines new development objectives for our company, in economic terms and as regards sustainability. In order to achieve these goals, we have allocated significant investments to continue introducing cutting-edge projects in the areas where we have a consolidated presence. These investments will also allow us to expand our scope, seizing the best opportunities for competition in the still highly fragmented sectors in which we operate. In an increasingly complex economic context, we wish to concretely contribute to recovery and the sustainable transition in Italy, with a multifaceted series of interventions, in line with the notices of the Recovery and Resilience Plan. Our multi-utility has now reached maturity, and not only in terms of age: this Plan crowns 20 years of progressive and linear growth, which has also generated value in the communities served. We have proved able to look to the future, extending our knowledge and perspectives, while being able to count on the solid foundations provided by our heritage and a consolidated strategy. Above all in the difficult times that our country has recently experienced, we have continued to guarantee quality services – as demonstrated by being awarded all tenders for regulated services held to date in the areas we cover – and to support those who have believed in us. This means our employees, customers, suppliers and shareholders, to whom we plan to pay dividends with further increases compared to what was previously defined, reaching 14.5 cents per share by 2025, following a growth rate of approximately 6%, in line with the expected trend in net results. Stefano Venier, CEO of the Hera Group The strategies set out in the Hera Group’s Business Plan to 2025 confirm and consolidate the orientations we have defined in the past, proving the effectiveness of the guidelines adopted by our multi-utility, which perfectly reflect European policies and the drivers of the UN Agenda for Sustainable Development. The improved cash flows expected will make it possible to self-finance our entire investment plan and remuneration for our shareholders. In order to focus our actions even more effectively, over the last two years we have begun measuring our progress with respect to the ambitious targets set for 2030, thus strengthening our commitment to the energy transition, the circular economy and technological evolution. Business activities and attention to ESG factors have always gone hand in hand for us, and over the years “shared value” Ebitda has grown at the same rate as the Group itself: in 2025 we expect this figure to reach 55% of total Ebitda, rising to 70% in 2030.

2022-01-26 This year, for the third year in a row, Hera has been included in the international index assessing gender equality, diversity and inclusion Sede Hera The Hera Group has confirmed its status as one of the world’s most inclusive companies, attentive to gender equality and promoting diversity. In 2022, the Group has indeed been included, for the third consecutive time, in the Bloomberg Gender-Equality Index, confirming and improving its results in all areas analysed. Hera stands out most importantly for its transparency in disclosure on these issues, as well as its inclusive corporate culture and its attention towards women in many areas, including equal pay. The Group obtained an overall score slightly above 80%, a significant increase over the previous year and better than both the sector average and the Italian companies analysed. This year, the index included 418 listed companies from 45 countries, selected from over 11,700, reflecting the international financial community’s growing interest towards companies with outstanding diversity policies. Hera’s presence in the 2022 Bloomberg Gender-Equality Index confirms the attention it has always reserved for these issues, following a path it has enhanced over time. Diversity policies are in fact an integral part of Hera’s business strategies. For over 10 years, a company Diversity Manager, accompanied by a team of female and male colleagues from different areas, has been committed to promoting diversity both inside and outside the Group, supporting initiatives intended to raise awareness and support, and developing projects geared towards these priorities. At Hera, promoting diversity, inclusion and people development is also central to human resource management. Professional growth takes place regardless of gender, and equal access is ensured by meritocratic systems that are guaranteed to be applied, with compensation and benefits tools linked to performance, role complexity and market comparisons. The Group counts 32.6% of women in roles of responsibility and, more generally, a 26.7% share of female staff, higher than the national average for the sector (2020 data). As further proof of the Group’s attention to these topics, it has also been included for some time in the Refinitiv “Diversity & Inclusion Index” and, boasting a position of world leadership in its sector, in the Dow Jones Sustainability Index World and Europe, the authoritative stock exchange index for evaluating social responsibility, which brings together the companies with the best sustainability performance in the world.

2022-01-20 Once again among Italy’s highest ranked employers, this year second place overall among companies nationwide for outstanding human resource management, Hera has reached its first milestone of the new year, which marks its twentieth anniversary. Training, welfare and digitalisation among the Group’s strong points. Sede Hera The start of a new year is always an occasion to look back in time, but even more so to look forward, taking a look at results and focusing on new objectives. In 2022, this is all the more true for the Hera Group, since this year marks the twentieth anniversary of its establishment. This is why receiving Top Employer certification for the 13th consecutive year, a sign of excellence in human resource management, is even more significant. Hera, after gaining recognition as the best company in 2020 and 2021, has found its place on the podium this year as well, ranking second overall in Italy among the 1,600 companies analysed by the Dutch Top Employer Institute. How? Over the years, Hera has provided itself with the best technologies, projects and initiatives to invest in the skills and well-being of its workers and select the most interesting talent on the market. One aspect which is increasingly crucial on the workplace as well, especially considering the changes in external contexts, is the care given to relations, which must be seen as real capital. Hera has decided to invest in this area, through means including training and corporate culture. HerAcademy, the Hera Group’s corporate university, plays a leading role in this field, and at the end of last year it organised a conference entitled “The evolution of social and relational dynamics for the ‘rebirth’ of work”, an event which called on leading figures from the world of business, academics and professionals. The goal was to compare experiences and practices, demonstrating that only by being part of a solid and motivated team is it possible to meet the challenges awaiting us outside and inside organisations. Moreover, the Hera Group has always stood out for its organisational methods, promoting agility in work, safety and the value given to the uniqueness of people, all within a context highly exposed to change. Alongside the increasing importance of training and welfare, along with a corporate culture dedicated to the inclusion of diversity, Hera has proven able to meet the challenge of digitalising services and therefore professional activities. Within this process, which is now in full swing and covers all company activities, even the most operational, employees have been accompanied but above all listened to, trying to understand and share their needs. Overall, this commitment has been recognised by the workers themselves, as shown by the latest employee climate survey, in which 82% of the company’s workforce took part and in which the company achieved excellent results. 16 years after the first survey, the overall satisfaction index has risen by more than 20 points, reaching 71 on a scale of 1 to 100. All of this testifies to the effectiveness of the steps towards improvement introduced following numerous communication initiatives. “For us, 2022 promises to be a very important year, encouraging us to look to the future with confidence, feeling proud of what we have done so far”, states Hera Group Executive Chairman Tomaso Tommasi di Vignano. “Ours is a twenty-year journey that began from local communities, from the people who live in them and to whom we provide essential services, but which has even more distant roots in the many companies out of which the Hera Group was born in 2002. It was very clear to us that our workers deserved to be at centre stage, because their skills and motivation are crucial to ensuring the continuity and constantly increasing quality of our services. This is why recognition as a Top Employer is so important: we have achieved this goal for 13 years, but we want to continue to take pride in it and invest in it, without ever taking it for granted. We will continue to promote the development of the idea of our organisation as a community and as a social environment, by constantly investing in the growth of our people.” Press release Hera Top Employer.pdf 2020-07-02 11:29:00 Sede Hera

2021-11-30 Hera’s smart gas meter 4.0, the first of its kind internationally in terms of safety functions, is already prepared for its first experimentation in the network with hydrogen, and its construction in recycled plastic further confirms the commitment to the energy transition and circularity. Not only equipped with outstanding technology and functions, including reducing gas dispersion into the atmosphere, the device is at the centre of the first experimentation in Italy with the use of hydrogen in domestic gas distribution Nexmeter With the Hera Group, also gas distribution is going green. NexMeter, Hera’s 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 the Hera Group’s 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. NexMeter gets the “stamp” for hydrogen operation The new NexMeter is now ready to be used with hydrogen distributed through the network, having obtained the “stamp of approval” certifying its compatibility with green gas mixtures. This is thanks to the metrological certification carried out by Tifernogas, a notified body pursuant to the relevant Directives (2014/32/EU MI-002 and MI-008), and the construction analysis concerning the compatibility of its materials with blending hydrogen and methane, carried out by RINA, an international engineering, consulting, inspection, quality assurance and quality control company in the energy 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 the entire Hera Group’s 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 Group’s broader strategy for developing hydrogen in a two-fold perspective: on the one hand, upgrading its assets, starting with the gas distribution networks, and on the other, creating new business opportunities, which Hera can make the most of by leveraging its multi-business expertise, including partnerships with other major industrial operators. A green device with environmental benefits with over 68% of its elements made in recycled plastic NexMeter’s advanced functions have numerous environmental and economic benefits: eliminating leaks reduces methane dispersion, which in turn is highly polluting, while the entire process of optimising gas network management has a positive impact on the performance and emissions of user appliances, first and foremost boilers. Its ability to detect and signal to users even the smallest gas leaks also helps contain costs in their bills. But that’s not all: the new NexMeter model will be the first meter on the market with most of its components made of recycled plastic, reaching over 68%. To achieve this result, the Hera Group, which has always been committed to the circular economy and regenerating resources, can count on the expertise of its subsidiary Aliplast, a leader in plastic recycling and regeneration, with plants in Italy and abroad, and an annual production of around 100,000 tonnes of recycled plastic. The metre’s manuals are also green and smart, with a QR code included on the meter instead of a classic instruction manual, to avoid paper consumption, and packaging in recycled cardboard. 300,000 NexMeter meters installed by 2023 in earthquake-prone areas The previous model of NexMeter, we should recall, was already equipped with advanced functions, including a cutting-edge "mini-computer" offering absolute precision and safety, since it is capable of intercepting in real time even minimal leaks or tremors in the event of earthquakes. Launched in 2019, these devices are still being installed, with 70,000 devices already in operation. Thanks to approximately 45 million in investments, the Group’s goal is to reach 300,000 NexMeters installed by 2023, 200,000 of which will be made of recycled plastic. The areas concerned are those served by the Hera Group’s distribution companies, starting with areas classified as at risk of earthquakes or where the latter have recently occurred, such as Emilia-Romagna and Friuli-Venezia Giulia. “With NexMeter, two years ago, we gave concrete proof of our ability to invest and innovate in a sector that remains quite traditional, such as gas distribution, paying particular attention to safety and reducing gas dispersion into the atmosphere, a factor that was also at the centre of debates during the recent Cop26 – states Stefano Venier, CEO of the Hera Group – Today, with this new version of the device, ready for hydrogen and made of recycled plastic, we are taking a further step forward, continuing to exploit our in-depth experience in this field with the skills offered by the most qualified partners, nationally and internationally. Actions and investments for the circular economy and innovation guide, indeed, the strategies set out in our Business Plan, in line with European guidelines and the goals on the UN 2030 Agenda. As a local multi-utility, we also have the task of growing while promoting sustainable development in the communities we serve, with advanced solutions that respect the environment and meet the safety and quality needs of citizens. NexMeter is a tangible example of our commitment to carrying out this mission in the best possible way.” “We are honoured to have contributed to the development of NexMeter which today added the use of green gas, especially hydrogen, to the safety functions, meeting the needs that the ecological transition imposes – states Motokazu Nishii, Head of Meter Device Business, Smart Energy System Business Division, Electric Works Company, Panasonic Corporation – This was possible thanks to Panasonic technology in ultrasonic measurement and safety functions with experience on the market for over 35 years, and, more importantly, to the collaboration with the Hera Group. The result is NexMeter which is a unique reference in the smart gas metering market. Panasonic will continue to work with the Hera Group to create a company where people can live better and more comfortably thanks to the use of clean energy and increasingly innovative solutions”. “The NexMeter, whose first version was already extremely innovative due to its advanced sensors and safety functions, has in this new phase achieved greater component sustainability and hydrogen compatibility” – states Cristiano Nardi, Executive Chairman of the Pietro Fiorentini Group – The project’s success confirms Pietro Fiorentini’s commitment towards establishing a continuous and constructive dialogue with our partners Hera and Panasonic, in order to work together in creating technologically advanced, competitive and fully environmentally friendly solutions, all of which are very important issues for our Group.” Press Release Green Nexmeter.pdf 2020-07-02 12:15:00 Nexmeter

2021-11-25 The winning proposal for the Bologna area, submitted by a consortium led by the Hera Group, focuses on sustainability, innovation and creating shared value. The contract with Atersir, the regulatory agency and contracting station representing the 50 municipalities involved, will last 15 years and have a total value coming to over 1.7 billion euro. Sede Hera 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. Chairman Tommasi: “a confirmation of the Group’s service quality and competitiveness” “We are particularly satisfied with this tender awarded for urban and assimilated waste management in the Bologna area”, comments Tomaso Tommasi di Vignano, Executive Chairman of the Hera Group. “It ensures continuity for our services in this area, and corroborates our work in two senses. On the one hand, it confirms the quality of our operations in one of the activities in which Hera has excelled since its establishment. On the other, it highlights the Group’s competitiveness in the waste management sector, even when dealing with tenders at European-level, for which we have developed specific skills that continue to generate positive effects for the company and for local communities.” CEO Venier: “alongside Municipalities for the transition to the circular economy” “With this assignment, the 50 municipalities covered by the new service contract have all the tools they need to face the challenges of the transition towards increasingly advanced and sustainable urban waste management and, more generally, towards a truly circular economy”, states Stefano Venier, CEO of the Hera Group. "These objectives, thanks to our support and expertise, have now become realistic and concrete. They cannot however be achieved without one fundamental element: the involvement and collaboration of people, who remain at the heart of our strategy".

2021-11-13 DJSI 2021 For the second year in a row, the Group leads its sector giving further recognition to Hera’s strategy, which combines attention towards sustainability with creating shared value DJSI 2021 The Hera Group has once again been confirmed as the world’s best multi-utility in ESG dimensions by S&P Global that selects the companies to be included in the Dow Jones Sustainability Indexes (DJSI). S&P Global has indeed announced the new ranking - effective as of November 22, 2021 - for its authoritative international stock exchange indices, which assesses the social responsibility of listed companies, based on sustainability performances for ESG factors. For the second consecutive year, Hera has been included in both the global (Dow Jones Sustainability World Index) and European (Dow Jones Sustainability Europe Index) indices, ranked best in the sector. The Group further raised its sector benchmark, achieving an overall score of 90/100 (improving compared to the 87/100 seen in 2020), against a sector average of 39/100. The ratings achieved: 92/100 in Environment, 90/100 in Economic & Governance and 88/100 in Social, reaching the highest sector score in all the three dimensions. This recognition is fully in line with the consensus found in ESG assessments thanks to a strategy focused on sustainable value creation in the last 20 years. Hera’s stock has been recently included in the MIB ESG Index, Italy’s first blue-chip index dedicated to Environmental, Social and Governance best practices, launched by Euronext and Borsa Italiana.

2021-11-11 The bid for the Modena area made by a temporary consortium led by Hera won thanks to its focus on sustainability, innovation and creating shared value. The contract with Atersir, the regulatory agency and contracting station on behalf of the 32 municipalities involved, will extend over a period of 15 years and will have a value of over 880 million euro. Sede Hera The Emilia-Romagna Territorial Agency for Water and Waste Services (Atersir), the regulatory agency and contracting station, has officially awarded the tender for urban and assimilated waste management in the Modean area to the temporary group of companies (RTI) made up of Hera S.p.A., Giacomo Brodolini Soc. Coop and Consorzio Stabile Ecobi. The numbers of the tender won by the consortium led by the Hera Group The contract concerns 32 municipalities in the Modena area, including the city of Modena, covering an area with approximately 490,000 inhabitants overall. As requested during the tender, the temporary consortium led by the Hera Group – the outgoing manager of this service for the same municipalities – will make significant investments to extend methods for collection over the entire served area that allow waste to be measured precisely, with the aim of minimising the amount of non-sorted waste delivered and increasing the quantity sent for recycling. The contract, to be signed in the upcoming months by Hera and Atersir, has a total value of over 880 million euro and a fifteen-year timespan. More sustainability and increased shared value for communities Thanks to the strong operational skills possessed by Hera and the other companies forming the temporary consortium to which was awarded the contract, the geographical area included in the service contract will be provided with collection models presenting innovative services and equipment, highly oriented towards sustainability, reduced waste and an increase in recycled materials. Innovation and sustainability, in any case, are values that Hera expressly pursued since the earliest stages of the tender, whose concreteness is proven by the results in terms of the percentage of sorted collection already achieved by the municipalities managed in the Modena area, with unit-pricing collection systems. The Ecosistema Urbano report published this week by Legambiente and Sole 24 Ore, which compares Italy’s capital cities, has also certified Ferrara’s leading position in terms of the percentage of sorted waste collected, for the third year in a row. This city is served by Hera with collection systems based on unit pricing, similar to those foreseen for Modena and the other municipalities in the Modena area. More dialogue and better environmental performances The key principles underpinning the bid submitted by the consortium led by Hera consist in awareness raising and a more active involvement of citizens and businesses, in order to encourage a reduction in the overall amount of waste, especially non-sorted waste, and ever-stronger emphasis on sorted waste collection. In fact, the experience gained until now shows that – regardless of the collection model proposed – the environmental performance of waste collection is better when a community is more aware of its own role. This is why, right from the earliest months of the new service contract, Hera will launch progressive communication and information campaigns aimed at increasing citizen involvement, and in so doing, further increasing the quality of the service, with a view to creating even more shared value for local communities. Executive Chairman Tommasi: “a confirmation of service quality and of the Group’s competitiveness” “We are particularly satisfied with being awarded the tender for managing urban and assimilated waste in the Modena area, comments Tomaso Tommasi di Vignano, Executive Chairman of the Hera Group. “This will give continuity to our presence in this area, and provides confirmation of two essential facts: on the one hand, the quality of our work with one of the activities that, since its inception, have characterized Hera's excellence, and on the other, the competitiveness that the Group has reached in the waste management sector. This is the case even when dealing with European-level tenders, for which we have developed specific skills that continue to generate positive effects for the company and for local communities.” CEO Venier: “alongside the municipalities in the transition to the circular economy” “With this tender, the 32 municipalities included in the new service contract have all the tools they need to face the challenge of the transition towards increasingly advanced and sustainable urban waste management and, more generally, towards a truly circular economy”, says Stefano Venier, CEO of the Hera Group. “These objectives, thanks to our support and expertise, have now become realistic and concrete. They could not however be achieved without one fundamental element: the involvement and collaboration of people, who remain at the heart of our strategy.” The 32 municipalities in the province of Modena covered by the tender Bastiglia, Bomporto, Castelfranco Emilia, Castelnuovo Rangone, Castelvetro di Modena, Fanano, Fiorano Modenese, Fiumalbo, Formigine, Frassinoro, Guiglia, Lama Mocogno, Maranello, Marano sul Panaro, Modena, Montecreto, Montefiorino, Montese, Palagano, Pavullo nel Frignano, Pievepelago, Polinago, Prignano, Riolunato, San Cesario sul Panaro, Sassuolo, Savignano sul Panaro, Serramazzoni, Sestola, Spilamberto, Vignola and Zocca.

2021-11-10 The Group consolidates the first nine months of the year with operating-financial indicators showing growth compared to the same period in 2020, and results exceeding the expectations set out in the Business Plan. Financial solidity, the pursuit of sustainable development and creating value for the local areas and communities served confirmed as strong points Risultati trimestrali 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. Gas Ebitda for the gas area – which includes natural gas distribution and sales, district heating and heat management services – rose to 333.4 million euro as at 30 September 2021, up 33.4% compared to 249.9 million euro in the same period last year. This growth, in terms of both revenues and volumes sold, was achieved thanks to the positive contribution coming from sales on traditional markets and on those subject to tenders, where Hera Comm has further consolidated its presence (with 8 lots of the last resort gas service awarded in 16 regions, 5 lots of the default gas service in 12 regions, effective as of October 2020, and 9 lots of the Consip GAS13 tender in 12 regions). These increased earnings are linked to significant rise in the energy services business, due to incentives deriving from tax bonuses and energy efficiency works, confirming the significant growth trend in this sector already recorded in the previous quarters of the year. A slight increase (+1%) was seen in the number of customers, which totalled 2 million. Furthermore, note that, from October 2021 until September 2023, Hera Comm has been awarded all lots of the default gas service tender and 6 out of 9 lots of the last resort gas service. The gas accounted for 37.7% of Group Ebitda. Water At 30 September 2021, the integrated water cycle area – which includes aqueduct, purification and sewerage services – recorded an Ebitda coming to 198.5 million, essentially unchanged from the 201.1 million euro seen in the first three quarters of 2020. This result is due to higher operating costs on networks and plants as a result of resuming activities after the lockdown, partially offset by a rise in revenues for new connections and higher other revenues. This also includes the benefits recognised by ARERA under the application of the new tariff method, linked to the significant investments made by the Group to implement measures aimed at resilience and sustainability in its plants, enabling it to continue guaranteeing citizens quality, efficiency and continuity of supply. Lastly, thanks to a bid geared towards sustainability and creating value, Hera was awarded the tender for integrated water cycle services for 18 years in 24 municipalities in the province of Rimini, including the capital city, with a contract worth approximately 1.7 billion euro. The integrated water cycle area accounted for 22.5% of Group Ebitda. Waste Ebitda for the waste management area – which includes waste collection, treatment, recovery and disposal services – rose to 218.4 million euro (+19.1%) as at 30 September 2021, compared to 183.3 million euro in the same period one year earlier. This growth was achieved thanks to the ability shown by the Hera Group – the nation’s leading operator in the sector – to make the most of the opportunities offered by this pro-cyclical business, i.e. one that is able to take advantage of the current economic recovery and the general recovery of markets after the lockdown. In fact, Hera has further augmented its outstanding set of plants with a series of transactions in the field of industrial waste treatment and environmental reclamation and restoration. The increase in earnings was caused by higher revenues linked to the increase in volumes of waste treated and electricity generation, and by the strong growth of the activities carried out by the subsidiary Aliplast, a leader in producing high-quality recycled polymers, against a significant increase in demand and in the selling price of recycled materials. In general, in the early months of 2021 as well, the Group continued to pursue all main initiatives related to the circular economy through front-line technologies and innovative structures. These include the production of renewable energy by developing the biomethane chain, including a collaboration with other companies found in the areas served. Hera has indeed signed a partnership with the company Inalca, part of the Cremonini Group, to establish a NewCo for transforming organic waste and agricultural waste into 100% renewable methane and compost. Lastly, Hera Business Solution, a turnkey multi-service offer for large companies, with integrated energy and environmental solutions all guided by sustainability, saw a further increase in its activities. The Group’s focus on protecting and reusing environmental resources was also confirmed by the increase in sorted waste collection, which stood at 64.8% in the first nine months of 2021, up slightly compared to the same period of 2020. The waste management area accounted for 24.7% of Group Ebitda. Electricity At 30 September 2021, Ebitda for the electricity area – which includes services in electricity generation, distribution and sales – amounted to 103.5 million euro, compared to 144.8 million euro in the first three quarters of the previous year. This result was mainly due to lower income from the dispatching market. Furthermore, a smaller scope of operations was seen in safeguarded markets, following the last tender awarded, in late 2020. These trends were partially contained by contributions to commercial growth in traditional markets and in new managed services, with innovative offers, value-added services and increasing investments to improve customer experience and customer segmentation. Furthermore, last June Hera Comm was awarded, through a tender, the gradual protection service for supplying electricity to SMEs in 9 Italian regions, for the period extending from 1 July 2021 to 30 June 2024. At 30 September 2021, electricity customers totalled 1.4 million, up 5.4% compared to the first three quarters of the previous year. The electricity area accounted for 11.7% of Group Ebitda. The manager responsible for drafting the company’s accounting statements, Luca Moroni, declares, pursuant to article 154-bis paragraph 2 of the TUF, that the information contained in the present press release corresponds to the documentation available and to the account books and entries.

2021-11-05 The Group was awarded the tender thanks to a bid focused on sustainability and value creation. An 18-year contract worth approximately 1.7 billion euro will be signed with Atersir, the contracting authority, in the upcoming months Sede Hera The Emilia-Romagna Regional Agency for Water and Waste Services (Atersir), acting as contracting authority, has officially awarded Hera the tender for managing the integrated water service in the province of Rimini (Emilia-Romagna region), with the exception of the municipality of Maiolo. The figures of the tender won by the Hera Group The tender concerns 24 municipalities in the Rimini area, including the province’s capital, and over 160,000 thousand users, distributed along a network extending over 3,000 km. Thanks to this tender, one of the first to be called in Italy, the new water distribution service in the Rimini area will be based on sustainability and innovation, and the Hera Group, which is also the outgoing manager for the 24 municipalities, will be responsible for the service over the next 18 years. The contract, which will be signed in the upcoming months between the Group and Atersir, is worth over 1.7 billion euro. Competition that creates shared value for communities In order to maintain management of this service, in a competitive context open to the most qualified operators in the water sector, the Hera Group has drawn up a proposal capable of reconciling service efficiency, and therefore economic impact, with best practices that guarantee high safety standards. Asset management and environmental aspects will thus be monitored by using innovative technologies that have already been operationally tested. Hera is also focusing on innovation to guarantee resilience in the management of the water cycle, a service characterised by a large number of infrastructures and therefore, more than other sectors, subject to the consequences of climate change. In addition to the high service quality already guaranteed by the Group in this area, the new management will therefore make substantial investments to increase the resilience of networks and plants and create increasing shared value for local communities. 250 million in investments to increase safety and resilience The Hera Group’s plan calls for a substantial part of the approximately 250 million euro planned for investments in the Rimini area over the next 18 years to be used to prevent and limit leaks, to upgrade the network and to further increase its reliability and resilience, thus providing the best guarantee of service continuity. The investment plan also includes measures to optimise the sewage system and upgrade the purification plants, as well as solutions for the implementation of rainwater collection plans. In order to increasingly improve the efficiency of networks and plants, the use of more traditional techniques will be enhanced with digitalisation and the most advanced technologies, including artificial intelligence and big data, already used by the multi-utility in other areas, for example to optimise maintenance activities or increase energy savings in purification. The Group’s proposal also guarantees a level of service that goes significantly beyond the standards required by ARERA, the Regulatory Authority, both in terms of the contractual quality inherent in relations with the user, and in terms of technical standards. Chairman Tommasi: “from competition in public services shared value for the territory” We are particularly satisfied with the awarded tender for managing the integrated water service for the province of Rimini”, explains Tomaso Tommasi di Vignano, Executive Chairman of the Hera Group. “We have always made our outstanding know-how available to the areas in which we operate, not only in terms of safety and service management, but also environmental sustainability, all of which will be confirmed and reinforced with the start of the new management. Tenders, not only in the water cycle, represent a challenge that the Group has prepared itself to face for some time. This achievement demonstrates once again how important it is for us, in addition to providing service quality and continuity, to invest and create positive effects for local communities.” CEO Venier: “local jobs and professional skills maintained” “The spirit with which we will sign this long term contract with Atersir for the integrated water service in the 24 municipalities of the Rimini area has nothing to do with simply continuing to manage it”, says Stefano Venier, CEO of the Hera Group. “In addition to maintaining local jobs and professional skills, we intend to create new value for Rimini and the municipalities managed.” The 24 municipalities found in the Province of Rimini involved in the tender Bellaria-Igea Marina, Casteldelci, Cattolica, Coriano, Gemmano, Misano Adriatico, Mondaino, Montecolombo Montescudo, Montefiore Conca, Montegridolfo, Morciano di Romagna, Novafeltria, Pennabilli, Poggio Torriana, Riccione, Rimini, Saludecio, San Clemente, San Giovanni in Marignano, San Leo, Sant’Agata Feltria, Santarcangelo di Romagna, Talamello and Verucchio.

2021-10-28 The Hera Group’s sales company has been awarded the lots for the Province of Rome, Campania, Calabria and Sicily, involving roughly 39,000 supply points and an annual supply of over 3.4 TWh of electricity, worth more than 580 million euro. Sede Hera Hera Comm will supply electricity to Public Administrations in the Province of Rome, Campania, Calabria and Sicily. The Hera Group’s sales company has in fact been awarded 4 of the lots put to tender by Consip, worth over 580 million euro, meaning that Hera will serve approximately 39,000 supply points overall, providing over 3.4 TWh of energy. The agreement will be effective as of the end of the year and will have a total duration of up to 24 months, depending on the supply option chosen, with a fixed or variable price. Hera Comm won this tender thanks to its advantageous economic offer, which also includes a Green Option, with 50% of the energy supplied coming from renewable sources. The Hera Group has thus confirmed itself as a leading player on the Italian energy scene, with 3.4 million customers, the third largest among Italian sales companies. Hera Comm has a well-established relationship with Consip, this being the third consecutive year in which it has been awarded lots in tenders called by Consip, for the supply of both electricity and gas.

2021-10-18 Being part of Italy’s first blue-chip index, launched today by Euronext and Borsa Italiana and dedicated to ESG best practices, gives Hera additional recognition for its focus on sustainability and creating shared value for all stakeholders Sede Hera The Hera Group has received yet another significant recognition, a reward for its way of integrating financial strategies and attention to sustainability: Hera has been included in the MIB ESG Index (Bloomberg gross return code: MIBESG), Italy’s first blue-chip index dedicated to Environmental, Social, and Governance (ESG) best practices. Announced today by Euronext and Borsa Italiana, the MIB ESG Index combines measurements of operating performance with ESG assessments, in line with the principles of the United Nations Global Compact. Inclusion in this index is based on an analysis by Vigeo Eiris, a Moody’s ESG Solutions company, and is designed to meet growing investor and market demand for sustainable investment instruments. The creation of this index is an important step in accelerating the transition to a sustainable economy and allowing investors to fund high-impact projects and companies in Italy and Europe. The index’s methodology was designed in a collaboration with the financial community, public institutions and regulatory authorities. Its main goals include facilitating the adoption of traditional ESG investment approaches by public and private investors and gathering consensus for sustainable and responsible investments. After being included one year ago in the Dow Jones Sustainability Index, World and Europe, with recognition as the best multi-utility worldwide by S&P Global, with today's inclusion in the MIB ESG Index, Hera’s successful corporate strategy has been further confirmed. The combination of growth in results and sustainability, alongside creating value for all stakeholders, defines the path taken by Hera ever since it was founded, 20 years ago. The Group’s Business Plans themselves highlight its various sustainability objectives – circularity, decarbonisation, risk management – to 2024 and 2030. Broken down by business area, these goals are based on investments that increase asset resilience, innovation, digitalisation, artificial intelligence and big data. More specifically, the Hera Group’s greenhouse gas emission reduction target is one of the most ambitious among Italian companies: 37% less by 2030 compared to 2019, as certified by the prestigious international network Science Based Target initiative (SBTi). Hera aims in particular to meet the “Well below 2°C” objective, conceived to limit the increase in global temperature to significantly less than 2°C compared to pre-industrial data, in line with the path set out by the Paris Climate Agreement. In addition to steadily improving its operating and financial results, Hera’s focus on ESG factors is accompanied by its stable governance, unique in the sector and rewarded this year with the highest ranking in Italy in the Integrated Governance Index, compiled by ETicaNews. A pioneer in the field of sustainable finance since it launched Italy’s first green bond in 2014, Hera successfully issued a sustainability-linked bond amounting to 500 million euro only a few days ago. A high level of interest was shown by international investors, whose subscriptions came to roughly four times the amount offered. This non-convertible bond’s issuance is linked to targets in reducing emissions and recycling plastics. Two years ago, Hera was also the first company in Italy to launch a sustainable revolving credit line, introducing a bonus mechanism linked to achieving specific environmental, social and governance (ESG) objectives. Green and, more generally, ESG financial instruments represent a fundamental lever with which Hera creates value and supports its commitment to increasingly regenerative and resilient development.

2021-10-13 Strong interest shown by international investors towards the 500 million euro, 12-and-a-half-year bond. The issue is part of a strategy aimed at sustainability, intended to reduce emissions and recycle plastics. The subscriptions received totalled around two billion euro, four times the amount offered Sede Hera The Hera Group – a pioneer in sustainable finance in Italy – has successfully launched its first sustainability-linked bond, worth 500 million euro. This non-convertible bond attracted a great deal of interest from international investors, who made subscriptions coming to four times the amount offered. The issue is part of a strategy aimed at sustainability, intended to reduce emissions and recycle plastics. One of the first companies in Italy to issue a sustainability-linked bond, Hera continues to act as a point of reference for ESG finance nationwide, with innovative instruments capable not only of supporting its commitment to sustainable development but also attracting growing attention on the market. Hera – it is worth recalling – was the first company in Italy to issue a green bond, in 2014, followed by a second green bond five years later, as well as the first ESG-linked revolving credit line, in 2018. Hera’s first sustainability-linked bond follows up on the publication, last 6 October, of its Sustainability-Linked Financing Framework (SLFF), with which the Group further strengthened the integration between its financial strategies and its attention to sustainability, outlining the metrics applicable to any financial instrument. The features of Hera’s sustainability-linked bond Hera’s first sustainability-linked bond, launched as part of the Euro Medium-Term Notes programme (last updated on 7 October) and reserved for qualified investors, amounts to a total of 500 million euro, repayable in 12 and a half years. The transaction saw significant participation coming from international investors (France, Germany, Netherland and United Kingdom), most of whom specialised in sustainable finance products. The strong demand, with subscriptions coming to around two billion euros, four times the offer, and the quality of the orders received, allowed the price to be set at an excellent level. An annual fixed rate coupon of 1.0% will be paid, while the yield at the time of issue is 1.077%. As of the interest payment date of 2032, a possible step-up (interest rate increase) has been included, should the Group fail to meet the targets for reducing greenhouse gas emissions, in tonnes of CO2 (rate increase of 0.20%), and the quantity of recycled plastic, in thousand tonnes (rate increase of 0.15%). The new issue, whose settlement date has been set for 25 October 2021, will be listed, as of the issue date, on the regulated market of Euronext Dublin, on the regulated market of the Luxembourg Stock Exchange and, at a later moment, on Borsa Italiana’s ExtraMOT PRO multilateral trading facility. This sustainability-linked bond is also expected to be assigned a rating in line with Hera’s (Baa2 with stable outlook for Moody’s and BBB+ with stable outlook for Standard & Poor’s). Interventions aimed at reducing emissions and recycling plastics The sustainability-linked bond is part of the Hera Group’s strategy aimed at reducing greenhouse gas emissions and increasing the amount of plastic recycled. These activities have already been launched or are included in the Business Plan, and represent Hera’s commitment to achieving the objectives on the UN 2030 Agenda. The bond is linked, as mentioned above, to meeting the sustainability targets contained in the Sustainability-Linked Financing Framework, with respect to which intermediate Sustainability Performance Targets (SPTs) have also been defined, which will be reported annually for the purpose of transparency. More specifically, the Hera Group aims to reduce greenhouse gas emissions by 37% within 2030 (compared to 2019), thanks to both the concrete actions taken within the Group and the involvement of suppliers and customers in electricity and gas sales. This is one of the most ambitious targets for a company in Italy, validated by the prestigious international network Science Based Target initiative (SBTi). As regards the second target, the Group aims to increase its amount of recycled plastic by 150% by 2030 (compared to 2017), thanks to factors including an increased plant capacity and an extension of the scope of action to include the recovery of rigid plastics. Hera is already a leader in this area, thanks to its subsidiary Aliplast, and is the only Italian multi-utility to have signed the Ellen MacArthur Foundation’s “New Plastics Economy Global Commitment”. “Our first sustainability-linked bond provides further confirmation of Hera’s commitment to sustainable development, with a focus on carbon neutrality and the circular economy, thanks to ESG financial strategies” states Stefano Venier, CEO of Hera Group “For some time, we have been committed to actions aimed at reducing emissions and recycling plastics, thus respecting our Business Plan and strategies for the energy and environmental transition. These issues are particularly relevant for us, considering the very nature of the businesses in which we operate, and we can make a real difference by responding to the many challenges we are currently facing, first and foremost climate change, and contributing to achieving the goals on the 2030 Agenda. Thanks to this new bond issued, we will be able to give further impetus to our activities in these areas.” The partners in the operation Hera’s sustainability-linked bond issue was coordinated and placed by BNP Paribas, Credit Agricole CIB, IMI-Intesa Sanpaolo, Mediobanca, Santander and UniCredit. The law firm Legance Avvocati Associati assisted Hera, while Linklaters supported the placing banks. Press release sustainability linked bond launch.pdf 2020-07-02 18:23:00 Sede Hera

2021-10-06 Hera is among the first companies in Italy to publish its Sustainability-Linked Financing Framework. An important point of reference also for issuing bonds in the future, its includes objectives linked to reducing greenhouse gas emissions and plastic recycling, in line with the Group’s Business Plan and strategies for energy and environmental transition The Hera Group – which pioneered sustainable finance in 2014, when it issued the first green bond in Italy – has further strengthened its integration between financial strategy and attention towards sustainability, with a focus on carbon neutrality and circular economy projects. The Group has in fact published – among the first companies in Italy to do so – its Sustainability-Linked Financing Framework (SLFF), which sets out the guidelines of its commitment to sustainable finance. This document outlines the metrics applicable to any financial instrument, and in particular provides a reference model for future bonds linked to reducing emissions and encouraging plastic recycling. More specifically, the Hera Group has introduced two key indicators in its SLFF, in line with the strategies outlined in the Business Plan for energy and environmental transition, and representative of Hera’s commitment to achieving the goals on the UN’s 2030 Agenda. The first concerns reducing greenhouse gas emissions: Hera aims to lower these emissions by 37% within 2030 (compared to 2019), thanks to both concrete interventions within the company and the involvement of suppliers and customers in electricity and gas sales. This is one of the most ambitious targets defined by a company in Italy, validated by the prestigious international network Science Based Target initiative (SBTi). The second is linked to the quantity of plastics recycled by the Group, an area in which it already shows leadership, through its subsidiary Aliplast. The only Italian multi-utility to have signed the Ellen MacArthur Foundation’s “New Plastics Economy Global Commitment”, it will extend its commitment in this sector, through means including increasing its plant capacity and extending its range of action to the recovery of rigid plastics. The goal is to increase the amount of plastic recycled by 150% within 2030 (compared to 2017). In the spirit of transparency, which has always been one of Hera’s hallmarks, intermediate Sustainability Performance Targets (SPTs) have also been defined with respect to the 2030 objectives, which will be reported annually. The Hera Group’s published SLFF now stands alongside its Green Financing Framework (GFF) – adopted by the company in 2019 – and responds to the growing attention shown by international investors towards sustainable financial instruments. This is an area in which Hera has always invested: after issuing the first green bond in Italy in 2014, the Group in fact offered a second “green” bond in 2019 and, in 2018, was the first company to launch an ESG-linked revolving credit line in this country. “With the Sustainability-Linked Financing Framework, we have consolidated the link between our financial strategies and the attention to sustainability which has always characterised us, for reasons including the very nature of the businesses we manage”, states Luca Moroni, Group Manager of Administration, Finance and Control. “Green financial instruments and, more generally, ESG criteria are in fact a fundamental lever to create value and support our commitment to an increasingly regenerative and resilient development. In particular, reducing greenhouse gas emissions and recycling plastics are particularly relevant areas for us, where we want to and can make a real difference in order to respond to the many challenges we are currently facing, starting with climate change, and contribute to meeting the goals on the 2030 Agenda”. Sustainalytics, one of the leading ESG rating agencies, has issued a Second Party Opinion certifying the Hera Group’s Sustainability-Linked Financing Framework’s consistency with the main international reference standards, first and foremost the International Capital Market Association’s 2020 Sustainability-Linked Bond Principles. In structuring its SLFF, the Group was supported by BNP Paribas, UniCredit and Mediobanca.

2021-09-13 By acquiring this Veneto-based company, the Hera Group has further consolidated its leadership in the waste management sector. From this and two similar transactions completed in the first half of 2021 in the industrial waste treatment sector, a consolidated contribution to Hera’s Ebitda coming to 20 million euro is expected Sede Gruppo 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. It will 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. In fact, all the acquisitions made by Herambiente also contribute to the objective of strengthening the geographical presence by increasing the penetration at local level, thus improving the efficiency and quality of services to local businesses and generating positive returns in the areas served, along with economic benefits for customers. “This new transaction is in line with the significant path of strategic development we are implementing in the industrial waste sector”, comments Tomaso Tommasi di Vignano, Executive Chairman of Hera Group. “When fully operational, thanks to the three acquisitions made in 2021, we will treat more than 300,000 additional tonnes of industrial waste produced by 3,300 new industrial customers every year, with a contribution to the Hera Group’s Ebitda coming to roughly 20 million euro, in addition to the value of the synergies expected from the integrations.” Press releaase Vallortigara acquisition.pdf 2019-07-03 11:02:00 Sede Gruppo

2021-09-09 Through its subsidiary EstEnergy, the Group has acquired 11% of the share capital of Ascotrade, a gas and electricity sales company, from Bim Gsp, now controlling it entirely. This transaction is part of a rationalisation and consolidation process following the Ascopiave partnership Sede Gruppo The Hera Group continues to expand its presence in the energy sector, in the Triveneto area in particular. Through its subsidiary EstEnergy, indeed, it has purchased 11% of Ascotrade, a company operating in gas and electricity sales, from Bim Gestione Servizi Pubblici in Belluno, for 21 million euro, thus controlling 100% of the share capital. This transaction is part of the process of rationalisation and consolidation of the companies controlled by EstEnergy, already the foremost energy operator in North-Eastern Italy, following the partnership between the Hera Group and Ascopiave. With the acquisition of the entirety of Ascotrade’s shares, the Hera Group has further consolidated its leadership in the energy area, where it already has a total of approximately 3.4 million customers.

2021-07-30 potabilizzatore_val_di_setta.jpg The certification process for the Val di Setta plant, located in Sasso Marconi and serving Bologna’s main aqueduct, has been successfully completed, confirming Hera’s ongoing commitment to managing and protecting water resources. Internationally, the Hera Group is the first utility to receive certification for a drinking water plant Potabilizzatore As of today, Hera’s Sasso Marconi (BO) drinking water plant, which also supplies Bologna, is certified 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. The Hera Group is 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 Hera’s 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. 38 million cubic metres of water per year, for 34 municipalities Hera’s drinking water plant in Sasso Marconi takes water from the Reno river and the Setta stream, makes it drinkable and serves 34 municipalities in the Bologna area, including the capital, with a total of almost 800,000 inhabitants. 42% of the overall drinking water supplied in the province comes from here, with an average of 38 million cubic metres per year. The plant works on a continuous cycle and is fully automated and controlled 24 hours a day by the Hera Group’s remote control centre, so that the slightest change in the service is reported and it is possible to intervene in real time, even remotely. “The virtuous management of water for us is fundamental, and with this certification we wish to formalize our commitment even more strongly. This is why we chose the Val di Setta drinking water plant”, comments Susanna Zucchelli, Group’s Water Manager. “One of the most important plants, it supplies important institutional and industrial facilities, and can therefore contribute to forming the sort of local network that is highly desired by this standard and enables us to share actions and best practices. One example is the collaboration initiated some time ago with Philip Morris, which has a large plant in Valsamoggia, served by our water treatment plant.” Press release Hera has the world's first AWS certified drinking water plant.pdf 2019-07-03 11:25:00 Potabilizzatore

2021-07-28 The half-year report shows significant growth in operating and financial indicators, thanks to the contribution coming from the Group’s main businesses. The pursuit of sustainable development and financial solidity are confirmed as strong points, as further verified by the recent S&P ESG Evaluation and the net debt/Ebitda ratio, which further improved to 2.5x Sede Gruppo 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 Today, 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. Hera thus continues along its uninterrupted path of development, promoting growth led by sustainability and innovation and relying on a strategy that balances internal growth and M&As and combines regulated and free market activities. 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 last week by S&P Global Rating’s ESG Evaluation. Gas Ebitda for the gas area – which includes services in natural gas distribution and sales, district heating and heat management – amounted to 244.1 million in the first half of 2021, a strong improvement (+21.6%) compared to the 200.8 million seen at 30 June 2020. This result was achieved mainly thanks to growth in both traditional and last resort markets. In particular, the Hera Group is increasingly consolidating its presence, with 8 portions awarded in the last resort gas service in 16 regions, 5 portions in the gas distribution default service in 12 regions and 9 portions of the Consip GAS13 tender in 12 regions. An increase in the energy services management business also contributed to growth, due to the greater activities linked to the insulation bonus and energy efficiency works for condominiums, district heating volumes and increased activities in Bulgaria. There was a slight increase in the customer base (+0.8% compared to the same period during the previous year), which totalled more than 2 million, to which the customers acquired from the Abruzzo company Ecogas will be added in the second half of the year. The gas area accounted for 39.5% of Group Ebitda. Water Ebitda for the integrated water cycle area – which includes aqueduct, purification and sewerage services – remained stable at 122.3 million at 30 June 2021, compared to 122.7 million in the first half of 2020. This result reflects higher operating costs on networks and plants, especially on electricity costs and on sludge disposal, compared to the previous year, partially offset by increased revenues from new connections and services for third parties. The integrated water cycle area accounted for 19.8% of Group Ebitda. Waste In the first half of 2021, Ebitda for the waste management area – which includes waste collection, treatment, recycling and disposal services – grew to 142.6 million, with a strong 16.5% increase compared to the 122.4 million seen at 30 June 2020, thanks in particular to growth in volumes treated, an increase in sales of recycled plastic products and higher revenues from electricity generation and biomethane production. The earliest positive impacts of the new acquisitions also appeared, especially from Recycla, which contributed 3.5 million to the results as of 1st January. Against a backdrop of recovery in the sector, the Group thus further confirmed and consolidated its leadership, partially due to partnerships in the industrial waste and environmental remediation and restoration sectors, which helped further expand its plant facilities, which now number around ninety, capable of handling all types of waste. Hera also continues to develop initiatives for an increasingly circular economy, from material recovery activities, thanks to the company Aliplast, which operates in plastic recycling and whose volumes are growing rapidly, to the production of renewable energy and biomethane, and Hera Business Solution, a “turnkey” multi-service proposal for large companies offering sustainable and integrated management of waste, water and energy. Further growth was seen in sorted waste collection, which stood at 65.8% at 30 June 2021, compared to 64.4% in the first half of 2020, thanks to the numerous projects introduced. The waste management area accounted for 23.1% of Group Ebitda. Electricity In the first half of 2021, Ebitda for the electricity area – which includes electricity generation, distribution and sales services – settled at 90.0 million, compared to the 97.0 million seen at 30 June 2020. Lower earnings in the safeguarded segment of the last resort market, due to a different scope of portions managed, and lower electricity generation activities were partially offset by the positive result of trading activities and strong commercial development, supported by innovative offers, value-added services and increasing investments to improve customer experience and customer segmentation based on different needs. Customers increased slightly (+1.4%), reaching over 1.3 million. The electricity area accounted for 14.6% of Group Ebitda. 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.

2021-07-21 The Hera Group ranks 5th internationally among the Utility Networks assessed by this rating agency’s Sustainable Finance analysts, thanks to its focus on sustainability, which has characterised the Group since its establishment, and its ability to manage risks and opportunities https://eng.gruppohera.it/group_eng/investor-relations/hera-stock Hera stock After being included in the Dow Jones Sustainability Index, World and Europe, in 2020, the Hera Group has once again confirmed its 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 today. 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. The Hera Group is the first company in Italy to publish its ESG Evaluation, in which it 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 it well above the international (68) and European (73) average and ranks Hera fifth internationally among Utility Networks (with the sector average coming to 74). This is a further important recognition of the attention that the Hera Group pays to ESG aspects in pursuing its strategy of sustainable, long-term growth, which has characterised it since it was established in 2002, which complements and goes hand in hand with its financial solidity, confirmed by its recent rating upgrade. In particular, in the ESG Evaluation, the Hera Group is 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. Among the Group’s most distinctive factors, the following were positively evaluated: a robust governance, characterised by a high level of independence and transparency; a proven ability to anticipate change and a solid track record in setting and achieving targets; an ability to capitalise on the principles of the circular economy by investing in technology and innovation, with results exceeding its peers; a long-term growth strategy anchored to sustainability principles (by creating shared value, in line with the goals on the UN 2030 Agenda); a good level of diversity, thanks to a high percentage of women in managerial positions, and the inclusive approach to local communities, through their constant engagement thanks to targeted initiatives.

2021-07-07 The two companies have partnered to form a NewCo for transforming organic waste and agro-food wastewater into 100% renewable methane and compost, using a plant equipped with the most efficient technologies and in line with circular economy principles. A 28 million Euro investment has been allocated. Hera and INALCA (Cremonini Group) together to produce biomethane Hera Group's subsidiary Herambiente, the national leader in the waste management sector, and the company INALCA (Cremonini Group), leader in meat production and food distribution, signed a partnership agreement to set up the NewCo BIORG for the production of biomethane, a 100% renewable fuel, and compost from the sorted-waste collection of organic and food waste. Through an investment of approximately 28 million Euro, a site owned by Herambiente in Spilamberto, in the Modena area, will be renovated using the best available technologies. The biomethane production plant will be operational by 2022. After the pioneering experience in Sant’Agata Bolognese (BO) launched in 2018, the Hera Group is thus continuing to develop its biomethane supply chain, with the aim of producing more than 15.5 million cubic metres per year by 2024, more than doubling the current volume. The partnership will generate significant environmental benefits, including for the local area In particular, in line with the Group’s emphasis on all aspects of environmental sustainability, the Spilamberto plant will not require using new land. The natural gas will be generated by the anaerobic digestion of organic waste from the Hera Group's sorted waste collection and waste from the processing of the agro-food industry, including the meat production cycle of INALCA, a company controlled by the Cremonini Group. When fully operational, production is expected to be 3.7 million cubic metres of biomethane per year, which will be injected into the gas network and returned to the local area for automotive use. The resulting environmental benefits are significant: each year approximately 3,000 TOE (tons of oil equivalent) of fossil fuel will be saved and approximately 7,000 tons of atmospheric CO2 emissions will be avoid. The operation will also enable the recovery of materials as well as energy. Instead of being disposed of, the waste resulting from the anaerobic digestion process, technically called solid digestate, will be further recovered, transferring it to the composting plant in Nonantola (MO) - currently owned by the Cremonini Group and to be transferred to BIORG - to produce approximately 18,000 tons of compost per year, which may be used as a biofertiliser in agriculture. Thanks to this NewCo, therefore, the Group will be able to make tangible contributions to the local-area circular economy in keeping with the guidelines of the recent PNRR (National Recovery and Resilience Plan) which promotes and supports the construction of new facilities for the production of biofuels. “The Hera Group has always been at the forefront in promoting environmental sustainability and the circular economy: all our projects go in this direction, while at the same time fostering innovation and the growth both of the company and the areas in which we operate” - states Andrea Ramonda, CEO of Herambiente. “Regarding the development of the biomethane chain in particular, our agreement with a first-class partner such as INALCA represents a further step forward for us after having established the first plant ever built in Italy by a multi-utility to produce biomethane on an industrial scale, the one in Sant’Agata Bolognese. Thanks to the know-how gained through this facility, we are always aiming at new initiatives for a circular economy transition, in line with our Strategic Plan up to 2024”. “This agreement consolidates and strengthens INALCA’s integrated and sustainable production model," the company’s CEO Luigi Scordamaglia explained. “In fact, the new plant allows the processing waste from our production activities to be fully exploited, confirming INALCA’s ‘zero waste’ commitment. In addition, an effective industrial synergy is achieved, with the production of biomethane and composting in two perfectly complementary plants. For this reason, this agreement with a company with know-how and state-of-the-art technologies such as Hera proves that only true innovation can generate the competitive sustainability that reduces impact on the environment while at the same time generating higher added value for the entire livestock sector”. The Hera Group is one of the largest Italian multi-utilities and operates in the waste-management, energy and water sectors, with over 9,000 employees who are committed every day to meeting the multiple needs of approximately 5 million citizens located mainly in Emilia-Romagna, Veneto, Friuli-Venezia Giulia, Marche, Tuscany and Abruzzo. Listed since 2003, it joined the FTSE MIB on 18 March 2019 and the Dow Jones Sustainability Index, World and Europe, on 23 November 2020. Its subsidiary Herambiente is the leading national operator in the waste management sector, with approximately 90 state-of-the-art plants that treat all types of waste. For additional information: https://eng.gruppohera.it; http://ha.gruppohera.it/?lang=2 INALCA S.p.A. is a Cremonini Group's company, European leader in the production of beef and processed meat products, cured meats, bacon and snacks (with the brands Inalca, Montana, Manzotin, Italia Alimentari, Fiorani and Ibis), and in the international distribution of top-quality food products (Inalca Food & Beverage). The company, which controls the entire production chain from breeding to distribution and is jointly controlled by the Italian state through Cdp Equity (Cassa Depositi & Prestiti Group), recorded revenues of EUR 2,121.5 million € in 2020, 30% of which from exports. Its industrial structure consists of 21 production plants (16 of which are in Italy and 5 abroad) and 26 logistical distribution platforms. It includes 9 farms (7 of which are in Italy and 2 abroad) and more than 100 breeding farms, for a total of 180,000 animals raised annually.

2021-06-30 The Hera Group has consolidated its leadership in industrial waste treatment and extended its scope of operations in northern Italy thanks to the acquisition of this Friuli-based company. Including the two further transactions to be completed within the summer, the final consolidated contribution to Hera's Ebitda is estimated at approximately 20 million euro. Hera The Hera Group, through its subsidiary Herambiente, Italy’s leading operator in waste treatment and recovery, 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), Italy’s largest industrial waste management company, 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. Important synergies are expected with its industrial centres in Pisa Province and at Ravenna, which have already been operational for some time. 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, and the contribution to the Hera Group’s Ebitda will come to approximately 20 million euro when the transactions are finalised. The strategic priority of Herambiente, which can count on a total of roughly 90 certified, state-of-the-art plants that combine efficiency, cost competitiveness and sustainability, is to offer companies waste treatment solutions in line with the circular economy. The new acquisitions, therefore, respect this strategic orientation and will guarantee positive returns in the areas served and economic benefits for customers. Lastly, all these transactions share a rationale that is part of Herambiente Servizi Industriali’s DNA: remaining close to its customers. Integrating these new platforms with the current set of plants will increase the wide availability of solutions in areas served for years by Herambiente, improving the efficiency and quality of services for local businesses. “With this acquisition, we continue to pursue our significant strategic development in the industrial waste sector, guaranteeing service continuity and competitiveness for companies,” comments Tomaso Tommasi di Vignano, Executive Chairman of the Hera Group. “In the upcoming months, we will close transactions with two further important companies operating in this sector. Taken as a whole, these three transactions will involve a total investment of 122 million euro and will add 200 qualified resources to our Group”.

2021-06-16 The Hera Group leads the overall ranking in this index, which measures the extent to which sustainability is integrated within corporate strategies. Hera is also at the top of the finance category, for the fourth consecutive year, and second in the special ESG Identity survey IGI 2021 Hera ranks 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, Hera also stands 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. “This recognition”, remarks Hera Group Executive Chairman Tomaso Tommasi di Vignano, “certifies once again the validity of the direction pursued since our establishment. Sustainability is in fact fully integrated within our activities, across the board, and represents a strategic asset in all respects. As is stated in our Articles of Association, Hera’s growth is accompanied by the generation of shared value for the communities and local areas served, which in turn are priority elements for defining financial and investment policies.” Sustainability at the heart of the Group’s strategies For the Hera Group, uninterrupted growth in operating results goes hand in hand with increasing attention to sustainability. In 2016, Hera 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. In 2020, shared value Ebitda rose to 420.0 million euro (+7.2%), equivalent to 37.4% of total Ebitda. This is in line with the path set out by the Business Plan, which projects this value at 50% of total Ebitda by 2024. Hera gave further evidence of the central role played by creating shared value when it introduced the concept of Purpose in its 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 Articles thus updated – in line with Borsa Italiana’s new Corporate Governance Code and best practices at European level – allow the Group to further strengthen its commitment to the energy transition and the circular economy. Lastly, as regards sustainable finance, in line with the growing interest shown by investors towards ESG factors, Hera has proven able to act swiftly, adopting innovative models that have led it to play a pioneering role in the sector. It was in fact the first company in Italy to launch a green bond, in 2014, followed by a second issue in 2019. Three years ago, the first sustainable revolving credit line was launched, introducing bonuses linked to achieving specific environmental, social and governance (ESG) goals. These include, for example, additionally reducing the carbon footprint in energy production, reaching new energy efficiency targets and improving sorted waste collection. 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. This year, IGI invited Italy’s top 100 listed companies, companies that publish a non-financial statement, and the top 50 non-listed companies to participate, thus reaching the highest number to date of companies analysed. The index now covers 60% of the companies listed on the FTSE Mib and 50% of Italy’s top 100 listed companies. Press release IGI 2021.pdf 2019-07-03 10:41:00 Press release IGI 2021

2021-02-24 Yet another recognition for the Group in this area. This prize, which analyses and valorises the best performances of Italy’s public service companies, was awarded today during the digital conference for its ninth edition Top Utility Analysis Attention towards gender equality, care given to diversity and inclusion: these issues are at the centre of the Hera Group’s strategies and corporate culture. This has been recognised among others by Top Utility, which today, during its digital conference, awarded to the Group first place in the Diversity category “for its efforts in making policies favouring diversity, inclusion and social responsibility”. Currently at its ninth edition, Top Utility analyses and valorises the changes made and performance shown by Italy’s 100 largest utilities on a yearly basis. Ranking as Top Utility in the Diversity category comes as recognition for the numerous initiatives introduced by the Hera Group, applied not only to its corporate culture but also to the management and development of its human resources. One example lies in the meritocratic systems planned and measured to be concrete applied, with compensation tools and benefits focused on performance, complexity in professional roles and market comparisons, regardless of characteristics involving gender or generation. The ensuing career paths see a growing percentage of women in roles of responsibility, now coming to roughly 30%. The attention given to these issues and the approach taken towards them by businesses is, furthermore, increasingly important for the international financial community, with investors showing growing interest towards listed companies with excellent policies in this area. For this reason as well, Hera has integrated these aspects within its Business plan, and provides transparent information on them each year in its sustainability report. “We are committed to making the Hera Group a place where everyone can feel ‘well’ and included”, remarks Susanna Zucchelli, Diversity Manager and Water Director at Hera. “A place where everyone knows they can make their own contribution to important projects that enrich the communities served, aiming at quality and favouring collaboration and communication. This is a company to which younger generations as well can look with interest as regards their future career. Receiving these recognitions gratifies us, motivates us and encourages us to do even better, to make our company a truly enabling party, developing and integrating these issues within the social fabric.” Hera’s leadership has also been recognised by other important awards. First and foremost, the Top Employer certification, achieved for the 12th consecutive year, confirming in 2021 as well the Hera Group’s top ranking overall in Italy. For years, furthermore, Hera has been included in the Bloomberg Gender-Equality Index and is among the leading companies in the Refinitiv Diversity & Inclusion Index.

2021-02-22 Depuratore Gruppo Hera Snam and Hera announce that they have signed a Letter of Intent for a technological collaboration aimed at developing hydrogen, for their own areas of activity respectively. Depuratore Gruppo Hera The aim is to test and subsequently implement a number of solutions able to respond to the decarbonisation needs of the Emilia-Romagna region in a cross-cutting manner, from production to mobility to individual citizens. This agreement will also contribute to promote the development of renewable energies in Italy, in line with the guidelines set out by the European Union. The accord involves several areas of action, starting from the collaboration on power-to-gas technology. Specifically, an innovative plant is at an advanced stage of design at the Bologna Corticella multi-utility treatment plant, which will transform excess renewable electricity into “green” hydrogen to be injected into the networks by exploiting purified water and returning oxygen, biogas and sludge to the water purification process, thus obtaining a mutually beneficial “symbiosis” between the two plants, with an additional environmental benefit. In the industrial field, the two companies will also study the application of hydrogen for thermal uses in the most energy-intensive sectors and with processes that are difficult to electrify. Other options under study include the creation of plants to extract green hydrogen from water, using the renewable energy generated by the Hera Group’s waste-to-energy plants, with the aim of contributing to the decarbonisation of industrial sectors such as the production of fertilisers and fuels. Finally, the Letter of Intent provides for a possible joint experimentation of injecting a mixture of natural gas and hydrogen into a portion of Hera’s distribution network in Emilia-Romagna, similar to what Snam has already done on its own transmission network. At the heart of this experimentation is the gas network of Modena. “The agreement with Hera - Marco Alverà, CEO of Snam said - is part of the collaboration we are starting with energy and industrial companies to develop hydrogen-related technologies and implement projects in different areas of the Italian territory. Hydrogen will be a decisive element, together with electricity from renewable sources, to enable Europe to become the first continent with net zero emissions by 2050. Snam intends to contribute to this path, by providing its infrastructure, combined with its skills and innovation capacity, to create a national hydrogen supply chain capable of accelerating the path to decarbonisation and create new opportunities for development and employment.” “With this partnership we wish to concretely contribute to the development of the hydrogen option to pursue the carbon neutrality of the territories, consistent with the commitment to sustainable development that has always guided our actions. – Stefano Venier, CEO of the Hera Group commented - Signing this protocol is part of the strategy outlined in our 2024 Business Plan, which calls for numerous actions and investments for energy transition and environmental protection in line with European strategies and the objectives of the UN 2030 Agenda. Green gases, including hydrogen, are a particularly interesting frontier for us because we operate in several businesses: by making available our cross-sector expertise and our extensive infrastructure platform we can create innovative examples of carbon neutral circularity among supply chains.” This agreement is likely subject to subsequent binding agreements that the parties will define in compliance with the applicable regulatory profiles.

2021-02-08 The Group has received Gold Class status for ranking as "Industry leader" in the Dow Jones Sustainability Index, one of the world's most authoritative stock market indices assessing ESG factors. Hera also given special mention as "Industry mover". Sede Hera The Hera Group has received a worldwide gold medal for social responsibility. S&P Global, indeed, has awarded the company its Gold Class 2021, the highest recognition reserved for companies included in the Dow Jones Sustainability Index (DJSI), the authoritative international stock market index assessing the ESG factors of roughly 3,500 listed companied with the highest capitalisation globally. This prestigious result was released today with the publication of the Sustainability Yearbook 2021, a report that contains the results of analyses carried out for gaining access to the index last year, and the names of companies that achieved the highest sustainability scores. Following its inclusion in the FTSE MIB in 2019, Hera participated in the selection process for the DJSI and, in only 2 years, rapidly rose in the classification, being included in the World and European indices at the same time and ranking as "Industry leader", i.e. the best "Multi-utility and Water" in the world, with a score of 87/100, compared to a sector average coming to 45/100. Compared to the other companies assessed by the DJSI, Hera stood out in particular for its environmental and economic sustainability, and its governance. The Sustainability Yearbook 2021 gives particular emphasis to the significant results achieved by Hera in the areas identified as most challenging for its sector, such as resource management and protection, the ability to grasp market opportunities and relations with stakeholders. In addition to Gold Class status, Hera also received special mention as "Industry mover", that is, the company that recorded the most significant improvement, rising by no less than 19 points compared to the score of 68/100 in 2019. These recognitions provide further confirmation of the valid sustainability strategy pursued by Hera, which represents its fundamental approach, substantiated once again by its Business plan to 2024, presented to investors 20 days ago. In the Plan, operating and financial results are expected to improve continuously, with a solid cash generation and ESG targets to 2030. The Plan foresees investments and initiatives for energy and environmental transition and technological evolution, in line with European strategies and the UN's 2030 Agenda. The most significant challenges include the field of renewable energies and pursuing carbon neutrality. In particular, Hera aims to achieve ambitious goals in reduction, following the criteria of the "Science Based Target initiative" especially as regards "Well below 2°C", (intended to limit the increase in the Earth's temperature to significantly under 2°C). Among the numerous international recognitions going to the Group for its attention towards sustainability, also note Hera's inclusion in 2020 in the FTSE4Good Index Series, a set of ethical indices conceived by FTSE Russell to encourage investments in companies that meet strict criteria in the area of ESG. Not by chance, attention towards ESG factors is an increasingly central issue for investors as well, and was included by Hera in its mission as of 2002, the year of its establishment.

2021-02-04 Aimed at contributing to decarbonising the agriculture sector, Hera has signed a memorandum intended to study the feasibility of a project for generating and using green hydrogen, linked to a concrete goal: fuelling the fertiliser produced by Yara Italia, the leader in this industry. Sapio is also involved, for the technological aspects and hydrogen management Sede Hera In times of climate change, a transition in the agricultural transition is a challenge as urgent as it is complex, because it requires not only reducing high water consumption but also limiting the emissions involved in the many processes concerned by agriculture, both directly and indirectly. The fertiliser sector is unquestionably among these processes, and is the subject of the memorandum signed by the Hera Group – one of Italy’s largest multi-utilities – with Yara Italia, a leader in nitric and complex fertiliser production, and by Sapio, a leading figure in the field of technical and medical gases. The memorandum is intended to explore the possibility of increasing sustainability in the agriculture sector, by using green hydrogen. A plant able to produce up to 500 tons/year of green hydrogen Based on this agreement, Hera, Yara and Sapio will begin a coordinated series of analyses that, within the year’s end, will assess the technological, economic and regulatory feasibility of a concrete project for using renewable energy and developing the green hydrogen industry. The project covers green hydrogen generation, transportation and use to fuel fertiliser production. In particular, the experimental plant intended for generating hydrogen would use the renewable energy produced by Hera’s Ferrara WTE plant, to produce hydrogen from water and thus fuel Yara Italia’s nearby industrial facility, dedicated to fertiliser production. Scouting the plant technologies will be done by Sapio, who will also be responsible for further evaluations concerning the technical solutions through which Yara’s facility will be supplied. An annual green hydrogen production capacity coming to 500 tons is expected. Commitment to green energy at the centre of Hera’s strategies By signing this memorandum, the Hera Group has given new impetus, only a few weeks after the approval of its Business Plan to 2024, to its commitment towards innovation, renewable energy and carbon neutrality. In line with European strategies and the goals on the UN’s 2030 Agenda, the environmental content of the Plan calls for not only promoting a circular economy and intervening to increase infrastructure resilience, but also all actionsfor energy transition and the fight against climate change, which increasingly involve biomethane, hydrogen and green syngas. The Group’s investments in technological innovation are fundamental in this sense, essential in searching for sustainable solutions in the area of so-called “clean energies”. Hera has been working towards sustainability in the agriculture sector for some time, for example through a circular and resilient management of water that also involves various projects in regenerating water resources and reusing waste water. “Developing clean energy”, remarks Stefano Venier, Hera Group CEO, “necessarily involves periods of research that, following the spirit underlying this memorandum, consolidate the expectations of our most advanced projects. Furthermore, it is equally important to set out these projects in a concrete and sustainable way, to meet the needs of sectors such as agriculture, which still have a significant environmental impact in terms of resource consumption, from water to energy. A commitment to sustainability, in any case, has always been in our DNA, as is further proven by Hera’s recent inclusion in theDow Jones Sustainability Index, and our decision to voluntarily apply the recommendations of the “Task Force on Climate-related Financial Disclosures” (TCFD) in our reporting as of the 2020 financial year. Our goal, reaffirmed in the Business Plan to 2024 as well, is to keep raising the bar, and forward-looking projects such as the one launched with Yara Italia and Sapio go precisely in this direction, exploring possibilities that, in a modular way, can be replicated elsewhere as well.” Yara Italia, the Italian branch of the Norwegian multinational Yara International ASA, a world leader in the fertiliser sector, has been successfully working for years to shape change as regards sustainability. Reducing CO2 emissions and water consumption, improving the environmental and energy sustainability of production processes and implementing regenerative solutions for soil that increase the effectiveness of fertiliser and thus reduce overuse, are at the top of the Group’s list of strategic priorities. Participating in this project is for Yara an additional, significant step in this direction. Sapio has maintained its vision of sustainability for almost a century, and is strongly committed to remaining at the forefront in developing and promoting the hydrogen sector, to allow Italy, which boasts an advantageous geographical position and important distribution networks, to become a European leader. Sapio, an active member of H2IT (the Italian Hydrogen and Fuel Cell Association) and the European Clean Hydrogen Alliance, covers all modalities of hydrogen production and distribution, through to its final applications, guaranteeing a high-quality offer with significant technological value. “Hydrogen is the future. And the future is now”, remarks the Chairman of the Sapio Group and the Associazione H2IT, Alberto Dossi. “We are witnessing an important historical moment, and it is equally important to collaborate with companies such as Hera and Yara. This example proves that this sector, in our country, is prepared to lead Italy to play a central role in the energy transition. We have both an industrial and a scientific mission, thanks to our relations with leading universities and research centres. To rise to the challenge of decarbonisation, the time has come to formulate a national strategy for hydrogen, that will allow us to reach the ambitious goals set out by the Ministry of Economic Development, which call for a usage of hydrogen coming to 20% within 2050.” Press release Sustainable agriculture Hera with Yara Italia and Sapio for green hydrogen.pdf 2020-01-24 10:51:00 Sede Hera
