Operating and financial highlights 2026 Ebitda: approximately 1.5 billion (+246 million compared to 2021) Total investments amount to over 4.1 billion (+53% compared to the last 5 years) Net debt/Ebitda at 2.8x in 2026 Dividends further increase to 15 cents per share in 2026 (+25% compared to last dividend paid) More than 130 million in NRRP (National Recovery and Resilience Plan) grants obtained to accelerate the Group’s investments in the areas served Industrial highlights Development driven by both internal and external (M&A) growth and balanced between regulated and free market activities Target of 4 million energy customers by 2026 2026 Shared-value Ebitda: 62% of total Ebitda, or roughly 910 million, in line with 2030 target of 70% Key goals for 2030 include a 150% increase in recycled plastics and a 37% reduction in emissions Solid point of reference to help local areas move towards the ecological and digital transition and social cohesion The Hera Group’s Board of Directors approved the Business Plan to 2026, which confirms the Group’s commitment to maintain a significant volume of investments over the next five years. Accelerating the evolution of all business areas in which it operates and the strategic guidelines defined one year ago, the Plan is in line with EU policies and responds to the particularly challenging external context, with the aim of continuing to create value for all stakeholders and confirming itself as a solid reference point for the areas served. Over 20 years at the side of the areas served, with preliminary Ebitda for 2022 rising to almost 1.3 billion As confirmation of the achievements made over the twenty years since its establishment, the Hera Group expects to close the 2022 financial year with growth in results exceeding expectations: preliminary Ebitda stands at approximately 1,285 million euro, roughly 60 million euro higher than 2021 Ebitda, while the Net debt/Ebitda ratio is expected to come to approximately 3.3x, improving compared to previous quarters, which is all the more appreciable considering the extraordinary market situation, the increase in the cost of energy commodities and the higher investments sustained in 2022, totalling roughly 780 million. An effective strategy to respond to the challenging context In a challenging external context – marked by high uncertainty caused by geopolitical instability, market volatility, rising inflation, higher energy prices and supply chain problems – the Group has turned challenges into opportunities and drawn up a Plan that follows up on the path previously undertaken. Its concrete projects are consistent with the main national and international policies on the energy transition, circular economy and innovation. Within this framework, cities will play a key role in mitigating climate change: Bologna and Padua are among the 100 selected by the EU Commission to become “smart zero-impact cities” by 2030, and the Hera Group has already launched investments and key projects to support municipalities in achieving carbon neutrality. Investments amounting to over 4.1 billion euro, supported by NRRP contributions The Plan to 2026 foresees total investments coming to over 4.1 billion euro, with an average of roughly 825 million euro per year, an increase over the previous Plan. Of these investments, 60% will go to regulated businesses and the remaining 40% to free market businesses. These figures include concrete initiatives in the areas served, to which more than 130 million euros in NRRP funding have already been allocated. Additional funds have been earmarked for urban waste collection and street sweeping projects, for which a decision is expected in the coming months.

With the publication of the 2023 Sustainability Yearbook – the report containing the analyses carried out to gain access the Dow Jones Sustainability Index (DJSI) – we have been awarded S&P Global’s Gold Class for the third consecutive year. This is the highest recognition for companies listed in the Dow Jones Sustainability Index, in which we confirmed our position as sector leader for the 3rd year in a row. In the most recent edition of the authoritative DJSI international stock market index, which evaluates listed companies on the basis of ESG factors, Hera ranked first internationally in its sector (Multi-utility & Water), with a score of 90/100 compared to a sector average of 34/100, calculated based on the three areas analysed: Environment, Social and Governance. A focus on sustainable development and creating value for the areas and communities served is a commitment and a responsibility that we have taken on since it was established in 2002, with the aim of guaranteeing quality and continuity in essential services for citizens and return value to all stakeholders. Our approach to sustainability, our mission and our purpose – which in 2021 became an integral part of its Articles of Association – indicate the direction in which we intend to continue, in line with the objectives of the United Nations 2030 agenda and with the creation of shared value in three main areas: energy, environment, local areas (and enterprises).

Always concerned with implementing policies concerning gender equality and enhancing diversity in the workplace, in 2023 as well we have been counted among the most inclusive companies worldwide. Today, we were confirmed – for the fourth consecutive year – as part of the Bloomberg Gender-Equality Index, which analyses the performance of companies engaged in supporting gender equality by developing dedicated active policies and transparency in communicating information. In the 2023 edition, which includes 484 listed companies, based in over 45 countries, selected out of more than 11,700 businesses, we confirmed our results in all areas under analysis with an overall score of 80.1%, above the Italian average (78.27%). The Group stood out in particular for equal pay, an inclusive culture and harassment prevention. This important result confirms our desire to keep valorising the uniqueness of people in a working context highly exposed to change, constantly committing ourselves to promoting and creating fair and inclusive workplaces, thanks to the development of dedicated policies and projects. This path stretches quite far into the past and has been enriched over time, starting with the signing of the Charter for equal opportunities and equality in the workplace in 2009 and the introduction – as early as 2011 – of the figure of the Diversity Manager who undertakes to promote the enhancement of diversity inside and outside the company, with dedicated awareness-raising initiatives.

We have been certified as a Top Employer for the 14th consecutive time, standing out for its job policies and ranking among the top 3 in Italy out of 1,600 companies analysed. The well-being of people, training, professional growth and transformation of skills are the main strengths that have allowed us to receive this prestigious award. It was conferred by the Institute based in Holland, a global body certifying corporate excellence in the HR field, after a close analysis that becomes increasingly selective every year and concerns specific parameters such as adequate salaries, working conditions, career opportunities, corporate culture, training and people development. With our pioneering vision, concrete decisions and increasing investments in human resources and training, we continue to take on the challenges of change, aiming at developing new skills and competencies. In this sense, a central role is played by HerAcademy, the corporate University founded precisely with the desire to generate new knowledge in response to the trends seen in the context, including an ongoing debate on current issues and collaborations with major national and international institutions. All training activities for Hera’s over 9,000 employees fall within this scope, so that continuous learning and people development are at the heart of the strategy, in line with the growing demand for profiles capable of overcoming the challenges of the transitions currently underway (digital, energy and environmental). In 2022 alone, 97% of the corporate population, including the most operational ones, attended training courses, totalling approximately 270 thousand hours, or roughly 30 hours of training per capita, well above the sector average. In line with this same vision, and above all as a response to the challenge of the energy transition, we have also launched a major talent acquisition campaign throughout Italy in recent months. The goal is to select and train, in collaboration with ManpowerGroup, 300 new resources with technical and operational profiles and include them, within 2023, in the Group’s various companies and in supplier companies.

We once again rank among the companies that pay the most attention to sustainability and ESG aspects internationally. Our latest ESG Evaluation, carried out by the Sustainable Finance analysts of S&P Global Ratings, has indeed also been published. This is a cross-industry assessment of our ability to effectively manage, in the medium and long term, our exposure to environmental, social and governance risks, as well as to grasp opportunities arising from the changes required by a constantly evolving international context. This year, we obtained an overall score of 81/100, making it one of the best companies internationally as assessed by S&P Global Ratings. This comes as further important recognition for the attention that we dedicate to ESG aspects in pursuing a strategy of sustainable, long-term growth, which has characterised us since Hera was established in 2002, and which complements and goes hand in hand with our financial solidity. In particular, in the ESG Evaluation just published, we are assessed by S&P Global Ratings as being strongly prepared to implement our strategy of creating shared value, contributing to the transition towards a circular and low-emission economy.

Financial highlights Ebitda* at 875 million euro (+2.4%) Net result* at 248 million euro (-5.6%) Net financial debt at 4,489 million euro, with net debt/Ebitda* at 3.62x Investments increase sharply to 463 million euro (+22.8%) Operating highlights Contribution to growth coming from core businesses Expansion in initiatives for the ecological transition and the circular economy Commercial margins maintained in the energy area Significant operating investments in networks, plus a significant effort in gas storage, as well as the completion of a number of M&As Solid energy customer base, approximately 3.5 million Today, the Hera Group’s Board of Directors, chaired by Tomaso Tommasi di Vignano, unanimously approved the consolidated quarterly report at 30 September 2022. Although the results achieved in the first nine months of the year are part of a complicated scenario, characterised by ongoing volatility on the energy market, which became even more pronounced over the last three months, as well as the complex current economic and geopolitical conditions and the gradual increase in inflation in the country, these figures highlight the Group’s ability to offset adversity, continuing to pursue the goals set out in its business plan, with increasing sustainable investments aimed at generating positive effects for the communities and local areas served. Moreover, the Hera Group’s resilient business model, the management policies it implements and its financial solidity have continued to enable it to seize the strategic opportunities offered by the market, to guarantee a high quality and continuity in its services while at the same time supporting and confirming the commitments made to all its stakeholders. Among the initiatives in support of stakeholders, note the flexibility shown towards the Group’s suppliers, who were able to revise their supply conditions based on inflation, and the significant gas storage initiative intended to support the customer base and the Italian gas system as a whole. As regards customers, thanks to the special attention to disadvantaged users, more favourable instalment terms than those provided for by law, an extension of the social bonus to include district heating, compliance with and maintenance of fixed-price contractual conditions, to date the performance in receipts for bills has been confirmed as essentially regular. Revenues rise to roughly 14.3 billion euro In the first nine months of 2022, revenues amounted to 14,320.1 million euro, up sharply (+122.9%) from the 6,424.3 million euro seen in the same period of the previous year. In particular, the energy segments showed significant growth mainly due to the increase in the price of energy commodities, which reached very high figures, especially in the third quarter of the year. Ebitda* increases to 874.8 million euro Ebitda* for the first nine months of the year amounted to 874.8 million euro, up 2.4% from the 854.4 million euro seen at 30 September 2021. The performance of the waste management area was particularly good, with Ebitda up 27.8 million euro, as was that of the water cycle area, up 7.3 million euro, fully offsetting the lower contributions coming from the energy area and the other services area. Financial operations essentially stable and pre-tax profit* at 347.5 million euro The result from financial operations for the first nine months of 2022 came to 89.5 million euro, basically stable compared to the 85.4 million seen during the first nine months of 2021. This change is mainly due to the increase in net financial debt generated by the trend in energy commodity prices compared to 2021. Net result and at 248.4 million euro With a tax rate of 28.5%, up from the same period in 2021 (26.2%) mainly due to the recognition of the non-recurring contribution against high utility bills (amounting to 2.3 million euro) and the recognition of lower benefits related to the tax credit on investments linked to the technological, digital and environmental transformation, the net result* and net profit* for the first nine months of 2022 amounted to 248.4 million euro. Net profit was largely stable compared to the 263 million seen at 30 September 2021. Strong growth in investments and net financial debt sensitive to the higher value of stored gas In the first nine months of 2022, the Hera Group’s operating investments, including capital grants, amounted to 463.3 million euro, up 22.8% compared to the 377.2 million euro seen in the same period of the previous year, with a major focus on resilience- and circularity-oriented projects, as set out in the business plan. The most significant interventions concerned plants, networks, and infrastructures, as well as regulatory upgrading focusing on gas distribution and the integrated water cycle, respectively involving a large-scale replacement of new-generation meters and specific interventions in the purification and sewerage areas.

Today, the Hera Group, acting through its subsidiary Herambiente Servizi Industriali (HASI), signed a binding agreement for a long-term partnership that provides for the acquisition of 60% of the company A.C.R. di Reggiani Albertino S.p.A. ® (hereinafter ACR), one of Italy’s largest companies in the reclamation sector, involved in industrial waste treatment, decommissioning industrial plants and oil & gas-related civil works, based in Mirandola (Modena). The new company will also bring together some of the remediation and global services activities carried out by HASI. This unprecedented transaction gives way to the leading national operator in the remediation and global services business, with an extensive presence throughout Italy. The Hera Group will thus further strengthen its leadership in the waste treatment sector, thanks to its approximately one hundred certified, state-of-the-art plants. It can now rely on ACR’s high operating capacity, time-to-market in services and significant machinery and equipment, which is already active in over 100 remediation sites with over 450 employees and having among its customers the major players in the oil & gas sector. With this partnership, on the one hand, the Hera Group will reach in advance the target in reclamation activities set out in its business plan, following up on the path of growth already achieved in this area in terms of both size and sustainability/circular economy, in line with the goals on the UN’s 2030 Agenda, which over the last 10 years have enabled it to double its customer base. On the other hand, ACR is implementing its strategic plan by making an agreement concerning commercial areas with a leading national player in the sector, strengthening its presence in its core remediation business and entering the world of global services. For further information Press release Visit Herambiente Servizi Industriali website 870x320.png The binding agreement signed today provides for the acquisition by the Hera Group of 60% of ACR, based in Modena and one of the major companies in the remediation and industrial waste treatment sector new_sede_hera_110.jpg

We have been confirmed as one of the companies most committed to promoting diversity, inclusion and people development. This has been certified once again by Refinitiv’s “Diversity & Inclusion Index”, whose 2022 edition examined over 12,000 companies worldwide and assigned to us a score that places us in the TOP10 of the international ranking, now first among multi-utilities and the top Italian company. This index is one of the main references for investors, who are taking an increasingly positive look at companies that adopt a Diversity & Inclusion (D&I) policy. After more than 10 years of projects, activities and initiatives aimed at reducing inequality, enhancing diversity and promoting an inclusive culture, this recognition provides further confirmation of the attention that we pay to policies in this area. This approach is confirmed by the Charter for Equal Opportunities and Equality at Work, signed as early as 2009 and matured internally, with the support of the working group led by the Diversity Manager, and later promoted outside the company context as well, to foster increasingly inclusive cities. This is also demonstrated by our personnel policies: our corporate welfare plan, for example, provides important support for Group employees and their families, with 5.3 million in services used last year alone. Hera also invests in developing internal and customised career paths, with 34% of women in positions of responsibility and, more generally, a female workforce coming to 27.3%, above the national industry average (2021 figures). For further information Press release Refinitiv Global D&I Index D&I in Hera Group refinitiv_870.png In the international ranking of Refinitiv’s 2022 “Diversity & Inclusion Index”, we are included in the TOP10 globally, becoming the world’s leading multi-utility and the top company in Italy for its commitment to diversity and people inclusion and development policies Refinitiv_2022 D&I_Logo_110.png

We presented our innovative “power to gas” plant named SynBioS (Syngas Biological Storage) at the Gastech exhibition in Milan. This plant will be able to convert renewable electricity and wastewater into “green” hydrogen and then into biomethane. SynBioS, in Bologna Corticella, inside the largest purification plant by users served among those we manage, is currently scheduled to be operational within 2023 and is linked to the support coming from incentives, including for example those coming from the PNRR. One of the first to be built internationally, the SynBioS plant has been made possible thanks to an investment coming to around 10 million euro and the synergies created between energy decarbonisation and water purification. Our multi-business know-how, combined with continuous investments in innovation, research and development, are in fact the strategic drivers that over the years have enabled us to develop cutting-edge integrated solutions in the field of “clean energy”, in line with the programmes outlined in its Business Plan. A plant to obtain biomethane from renewable electricity The plant, which uses “power-to-gas” technology to convert renewable electricity into synthetic natural gas, not only increases the pollutant reduction potential of the sewage treatment plant, but also allows excess renewable energy to be valorised by reusing biomethane in the city’s distribution network, which thus acts as a long-term storage facility. The figures: the annual methane gas consumption of 1,200 households sustainably covered At full capacity, coming to 1 MW, the plant will be able to produce approximately 190 Nm3/h of green gas, preventing roughly 50 Nm3/h of carbon dioxide from being released into the atmosphere, corresponding to the annual impact of about 400 cars. This is a true flagship project from the point of view of the circular economy: while producing enough methane to cover the annual consumption of 1,200 households, in fact, the plant will use the wastewater produced by about 50 people every day, also helping to increase the quality of the purification process itself. For further information Press release Gruppo Hera_Bologna_870.png Within 2023, we will build a system in Bologna equipped with “power to gas” technology, integrated with our largest water purification plant. One of the first to be built internationally, it will be able to convert renewable electricity and wastewater into “green” hydrogen and then into biomethane new_sede_hera_110.jpg

What happened to the Marmolada glacier is unfortunately irreversible, as are other devastating effects of climate change, now plain for all to see. If we are able to successfully reduce climate-changing emissions, this could help to contain climate change, which has by now evolved into an established crisis, and its effects. Energy Solutions for the Climate, the report in which we report on the reduction of our emissions, is online This is the focus of the new edition of our thematic sustainability report Energy Solutions for the Climate, which has just become available online and will soon be available at our main customer service branches. In the report, we present some of the important results we have already achieved on the way to the major target of reducing emissions by 37% by 2030, validated last year by the prestigious international network of the Science Based Targets initiative. Combating climate change: a commitment now enshrined in our Articles of Association We have been active for years in the 'pursuit of carbon neutrality', a goal that deliberately coincides with one of our three drivers for the creation of shared value, which was added to our Articles of Association as our 'purpose’ in 2021. For us, in short, the fight against climate change is crucial and translates into a wide-ranging action that ranges from the sale of renewable electricity and gas with CO2 offsetting to the promotion of energy efficiency, as part of an inclusive logic that involves customers and suppliers, thus contributing to increasing the very chances of success of the transition also promoted by the EU. For further information View the new edition of the online report banner_energy.png Efforts continue to reduce overall climate-altering emissions, which we aim to reduce by 37% by 2030.

Financial highlights Revenues at 8,896.0 million euro (+112.8%) Ebitda* at 631.2 million euro (+3.3%) Net profit* at 201.7 million euro (-12.7%) Net financial debt at 3,682.4 million euro, with Net debt/Ebitda* at 2.96x, confirming the Group’s financial solidity Operating highlights Contribution to growth comes from main businesses Further development of initiatives for the ecological transition and the circular economy Solid energy customer base, amounting to roughly 3.5 million The Board of Directors of the Hera Group unanimously approved the consolidated operating results for the first half of 2022. Despite the complicated scenario, marked by ongoing volatility on energy markets and international geopolitical conflicts, the Hera Group’s management policies and its solid and resilient business model have once again proven effective. The Group has thus achieved results that guarantee both quality and continuity of services and the constant creation of value for all stakeholders. As regards changes in the scope of consolidation, the energy areas benefited from the acquisitions, through the subsidiary Hera Comm, of 90% of the Abruzzo company Eco Gas and 100% of the company Con Energia. Also note that Hera Comm was awarded the gradual protection service for electricity supply to SMEs in 9 Italian regions. In the waste management area, compared to June 2021, note the integration of 80% of the Vallortigara Group, which provides services to industries, public administrations and citizens and manages a multi-purpose platform for special waste treatment in the Veneto region. Furthermore, note the acquisition on 30 June 2022, through the subsidiary Marche Multiservizi, of 70% of Macero Maceratese, which operates in the waste management sector. With this additional transaction, the Hera Group has strengthened its nationwide leadership in the waste management sector, and industrial waste management and treatment in particular. Revenues reach roughly 8.9 billion euro In the first half of 2022, revenues amounted to 8,896.0 million euro, with a sharp increase (+112.8%) compared to 4,179.7 million euro seen at 30 June 2021, thanks to the contribution coming from all major business areas. The energy areas in particular showed significant growth, mainly related to the increase in commodity prices. Furthermore, growth in energy services was related to energy efficiency in residential buildings (insulation bonus and 110% super-bonus) and increasing activities involving value-added services for customers. As regards the waste management area, instead, higher revenues mainly came from energy production, the expansion of business customer base and changes in market prices. Ebitda* increases to 631.2 million euro Ebitda* for the first half of 2022 rose to 631.2 million euro (+3.3%), against 610.9 million euro at 30 June 2021, up 20.3 million euro, mainly due to contributions coming from the energy, waste management and water areas. Financial operations improved, pre-tax profit and net profit substantially stable The result of financial operations for the first six months of 2022 came to 50.9 million euro, with a 4.2 million euro improvement compared to 30 June 2021, mainly due to lower financial expenses on long-term debt (the result of debt optimisation operations) and lower expenses from discounting provisions. Compared to the equivalent figures for the previous year, pre-tax profit* thus amounted to 284.0 million euro, up slightly (+0.9%) over the 281.5 million euro seen one year earlier, while net profit* pre-minorities, equal to 201.7 million euro, remained in line with that as at 30 June 2021 (206.4 million euro). Net results* at 201.7 million Net profit* at 30 June 2022 amounted to 201.7 million euro, down from 231.1 million in the first half of 2021, which included non-recurring items amounting to 24.7 million, caused by a tax realignment and the partial repurchase of some bonds. Investments rise; net financial debt affected by the higher value of gas storage In the first half of 2022, the Group’s operating investments, including capital grants, amounted to 287.1 million euro, up sharply (+16.3%) compared to the 246.9 million euro seen during the same period of the previous year, and were mainly related to works on plants, networks and infrastructures. Alongside the latter, regulatory adjustments mainly concerned gas distribution, with a large-scale replacement of meters, and the purification and sewerage area. Net financial debt went from 3,261.3 million euro at 31 December 2021 to 3,682.4 million euro at 30 June 2022, showing an increase coming to roughly 421.1 million euro. This was mainly due to a change in net working capital*, due to the higher value of stored gas, already contracted to better serve the needs of the upcoming thermal season and guarantee quality and continuity of service to customers. The net debt/Ebitda* ratio increased slightly, reaching 2.96x. Conto economico (mln €) giu-22 Inc.% giu-21 Inc.% Var. Ass.

For our circular economy projects, we have obtained from Bureau Veritas Italia, a leading multinational certification company, the certificate for the AFNOR XP X30-901 standard, the first issued to an Italian multi-utility. The French AFNOR XP X 30-901 standard is now the main international reference for implementing a management system for circular economy projects. This model, in fact, provides a point of reference for all companies that, wishing to adopt circular solutions within their production systems, need a certifiable guide on which to base themselves. Certification for the AFNOR standard encourages standardisation of corporate methodologies for project management, achieved by adopting a concrete tool to carry out a critical analysis of these methods in relation to areas of action and environmental, social and economic factors. More specifically, it is based on a matrix that combines the 3 classical factors involved in sustainability (environment, economy, society) with the 7 action areas of the circular economy (Sustainable Procurement, Eco-design, Industrial Symbiosis, Functional Economy, Responsible Consumption, Product Life Extension, Efficient Product and Material Management). We have implemented a management system for our circular economy projects and have set up the following three, according to this matrix: the “HOVE” project to transform the exhausted vegetable oils collected in the served area into biofuel; a project to integrate circularity criteria into procurement; and a project to reuse purified wastewater. Bureau Veritas Italia was therefore called upon to analyse them in detail and has certified the compliance of the company’s management system for circular economy projects with the AFNOR standard. For futher information Press release Visit Bureau Veritas website BV-logo_870.png We have successfully concluded our certification process with the multinational Bureau Veritas, the sector’s leader, confirming the commitment we’ve shown over the years with numerous projects and initiatives favouring the circular economy BV-logo_110.png

The Hera Group, acting through its subsidiary Marche Multiservizi, the leading operator in public utilities in the Marche region, has acquired from the Iesari family 70% of Macero Maceratese, a long-standing company in this area, operating since 1969 in the waste management sector, whose customers are mainly located in the province of Macerata and to a lesser degree in the remaining provinces of the Marche region, as well as in the neighbouring regions of Abruzzo and Umbria. By operating on the free market and creating significant synergies both with the other companies of the Hera Group active in waste treatment and with its own industrial poles already operating in the province of Pesaro and Urbino, Marche Multiservizi expects, when in full force, a 10% increase in turnover and a 5% increase in Ebitda, with an overall benefit for all stakeholders in the area served. History and activities of Macero Maceratese Widely recognised and consolidated in central Italy, for over 50 years Macero Maceratese has been dealing with services related to managing the waste produced by local industries, including SMEs and large-scale retail trade, and activities related to managing municipal waste, partially destined for energy recovery and landfills, and partially for treatment and recovery. With 30 employees working at three sites in Macerata, Piediripa di Macerata and Martinsicuro (Teramo province), in the last three years Macero Maceratese has handled an annual average of 58 thousand tonnes of waste. The main plant in Piediripa di Macerata is home of two large-capacity pressing plants, a shredding plant and a waste sorting plant, which boast ISO 9001, ISO 14001 and OHSAS 18001 certification, modern equipment and qualified personnel. For further information Press release sede MMS_870.png With this additional transaction, which follows up on others carried out in previous years, the Hera Group has strengthened its national leadership in the waste management sector, regarding in particular industrial waste management and treatment sede MMS_110.JPG

According to Arera, the Regulatory Authority for Energy, Networks and the Environment, we are among the top providers in Italy regarding technical quality of the water service. The ranking, drawn up after a careful assessment by the Authority, refers to the two-year period 2018-2019 and is designed to verify the quality and efficiency of water infrastructures. Interruptions to services, leaks, quality of water supplied, adequacy of the sewerage system, quality of purified water and disposal of sludge. These are the 6 macro-indicators on which each of the water service operators active on the national territory has been analysed and classified. By analysing the data up to 17 July 2020, the Authority was able to award a prize to those who have achieved, maintained and improved on the objectives set. We figure at the top of the ranking, scoring particularly well with regard to the levels of service in the regions of Rimini, Bologna, Ravenna and Forlì-Cesena. This result rewards our use of innovative technologies for the efficient management of the water cycle, and the work of our many professionals, who are committed to ensuring continuity, safety and quality of service on a daily basis. The involvement of local governments has also been fundamental to achieving this goal, with whom we have always teamed up to guarantee citizens an increasingly better service.

We are the foremost company in Italy for the importance of sustainability policies, fully and consciously incorporated within business strategies. This is demonstrated, for the second consecutive year, by the Integrated Governance Index, the main quantitative index to measure the integration of ESG factors in corporate governance, managed by ETicaNews and presented in Milan at the ESG Business Conference. Sustainability at the heart of our strategies Ever since our foundation, sustainability has been at the core of our strategy. This award is therefore fully in line with the cultural transformation that began 20 years ago and has concerned all aspects of the Group. ESG factors are indeed fully integrated within our activities and represent a strategic asset in all respects. Our attention to sustainability is also proven by the recent transformation of subsidiary Hera Luce into a Benefit Corporation. This decision represents a further step towards sustainable development, following last year’s introduction of the concept of corporate purpose into our Articles of Association.

As pioneers in sustainable finance since 2014, when it issued the first green bond in Italy, we have published our new Green Financing Framework (GFF) that consolidates the transparency policy we pursue towards the investors. Sustainability and ecological transition at the core of the new GFF The new GFF is a landmark for issuance of green bonds and for new green facility agreements related to the following areas: “Sustainable Water and Wastewater Management”, “Circular Economy and Pollution Prevention and Control” and “Energy Efficiency and Energy Infrastructure”, selected in compliance with the Green Bond Principles 2021 (GBP) published by the International Capital Market Association (ICMA) and the Green Loan Principles 2021 (GLP) published by the Loan Market Association (LMA). Furthermore, the GFF sets out our commitment in the direction of the EU Taxonomy and of the Climate Transition Finance Handbook. Consistently with our positioning characteristic since our establishment and with the strategies outlined in the 2025 Business Plan, the new GFF intends to promote, also through the sustainable finance leverage, the achievement of the goals related to the ecological transition, to which we direct the development of our businesses.
