Press Releases and Notices

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.

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 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.

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 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.

This year, for the third year in a row, Hera has been included in the international index assessing gender equality, diversity and inclusion 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.

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. 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 2022-01-20 11:29:00 Sede Hera Sede Hera 2020-07-02
