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.

2021-09-29 In the international standing provided by Refinitiv’s 2021 “Diversity & Inclusion Index”, the Group ranks 42nd globally, second overall among multi-utilities and third in Italy. Policies promoting diversity, inclusion and people development are increasingly central for investors. Hera has been confirmed among the listed companies most committed to promoting diversity, inclusion and people development worldwide. This emerges from the 2021 edition of the “Diversity & Inclusion Index” published by Refinitiv, which examined approximately 11,000 companies globally and awarded the Hera Group with 42nd place in the world ranking, 2nd best multi-utility in the world and 3rd best among Italian companies. The “Diversity & Inclusion Index” was designed and created by the international financial information giant Refinitiv and analyses the performance of companies on the basis of a wide set of sustainability KPIs. It provides one of the main references to investors who look favourably at companies adopting policies oriented towards Diversity & Inclusion (D&I). These issues are becoming increasingly important worldwide, alongside a growing awareness on the part of companies themselves of the benefits linked to ESG factors from an economic and social point of view, in terms of sustainability and wellbeing. For Hera, this offers further confirmation of the attention the Group has always paid to these issues, focusing on the wellbeing and development of its over 9,000 employees, promoting an inclusive culture both inside and outside the company. The Group was a pioneer in this area, signing the Charter for Equal Opportunities and Equality on the Workplace in 2009 and introducing the position of Diversity Manager in 2011, to promote diversity, equal opportunities and equality on the workplace. One outstanding example of the Group’s personnel policies is its corporate welfare plan, which supports employees and their families, with 4.5 million in services used in 2020 alone. Hera also invests in developing personalised internal career paths, with 32.6% of women in positions of responsibility and, more generally, a 26.7% share of female staff, above the national average for the sector (2020 figures). Investment in training is also crucial, with an average of approximately 26 hours per capita and activities involving 95% of employees last year.
