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.

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.

After being the first company in Italy to issue a "green" debt instrument, in 2014, we have successfully launched, in the context of Euro Medium Term Note Programme (EMTN), our third “green bond” reconfirming itself as a reference player for sustainable finance, also at an international level. After the publication yesterday of our new Green Financing Framework (GFF), certified by an independent advisor and already in line with the EU Taxonomy, with this issue we gave to the market the chance to invest in the activities of the Group, in line with the EU Taxonomy. The characteristics of the new green bond and the projects financed Our third green bond (Moody’s rating Baa2 with stable Outlook and Standard & Poor’s rating BBB+ with stable Outlook), amounts to 500 million euro overall, repayable in 7 years with a 2.5% coupon and a 2.639% return. The issue date for the new green bond is expected to be May 25. The new green bond is represented by senior, non-convertible and unsecured/not guaranteed notes, reserved to qualified investors. The funds will be used to finance or refinance numerous projects, already implemented or included in the Business plan to 2025, selected on the basis of the provisions of the Green Financing Framework (GFF), that pursue one or more of the goals in the UN's 2030 Agenda or Sustainable Development Goals (SDGs). These projects have been subdivided into 3 areas: integrated water cycle (aligned with SDGs No. 6, 13 and 14): waste water management projects, sewerage and water infrastructures furthering resilience and adaptation to climate change; circular economy and pollution prevention and control (meeting SDGs No. 11, 12 and 13): innovative projects in plastics manufacturing, biogas and biofuel production for the use in transportation, the waste collection systems, anaerobic digestion and the compost of organic waste, and vehicle fleets for environmental services; energy efficiency and infrastructures (consistently with SDGs No. 7, 11 and 13): from energy production through photovoltaic systems and geothermic, to district heating networks, from installing devices and equipments for energy performance regulation and control, to renewable energy technologies, from hydrogen introduction networks to power transmission and distribution networks.

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. For further information Press release Green Financing framework and opinion sede_hera_870.png It sets out the guidelines for issuance of green bonds and for new green facility agreements. We are the first multiutility in Europe to publish a framework certified as being in line with the EU Taxonomy sede_hera_110-2.jpg

Financial highlights Revenues at 5,312 million euro (+133.8%) Ebitda at 374.0 million euro (+3.3%) Net profits at 137.8 million euro (-1.8%) Net debt at 3,455.2 million euro, with net debt/Ebitda ratio at 2.8x Operating highlights Good contribution to growth comes from the main businesses, in particular the energy sectors and the waste management area Further development of initiatives for the ecological transition and the circular economy, thanks to state-of-the-art plants and increasingly green services Solid energy customer base, with approximately 3.5 million customers The Hera Group’s Board of Directors, chaired by Tomaso Tommasi di Vignano, unanimously approved the consolidated results for the first quarter of 2022. Despite the fact that the results for the first quarter of 2022 were achieved against the backdrop of an extraordinarily difficult international scenario, marked by energy market volatility and geopolitical conflicts, Hera’s management policies – based on its solid and resilient business model – proved to be effective and enabled it to show further growth in results. Following up on the indications contained in the Business Plan to 2025, the Group thus continues to create value for stakeholders while ensuring, at the same time, quality and continuity in services. As regards regulated services, in November 2021 Atersir definitively awarded the Hera Group the tender for the concession of the integrated water service for 24 municipalities in the province of Rimini, including the capital, with a contract worth approximately 1.7 billion euro. The Hera Group, which was also the outgoing manager, will therefore be responsible for this service from 2022 to 2039. A few weeks later, lastly, Atersir definitively awarded the Hera Group, for a period of time covering 15 years, the tenders for the municipal waste collection services in the Modena and Bologna areas, with a total scope of 1.5 million inhabitants and a value coming to over 2.5 billion. Revenues at roughly 5.3 billion euro (+133.8%) In the first quarter of 2022, revenues amounted to 5,312.0 million euro, up sharply from 2,271.8 million euro seen in the same period one year earlier. The energy sectors in particular contributed to this result, showing significant growth due to increased trading and the rise in commodity prices, as well as higher volumes of gas sold as a result of new lots won in tenders and lower winter temperatures. In addition, growth in energy services was related to energy efficiency in residential buildings (insulation bonus and 110% tax super-bonus) and increased activities for value-added services for customers. Revenues from the waste management sector were also up, mainly due to energy production, higher prices in the recovery market and new acquisitions in the industrial market. Lastly, revenues from network services increased, both regulated and for third parties, as did revenues from the public lighting service. Ebitda rises to 374.0 million euro (+3.3%) Ebitda went from 362.0 million euro in the first three months of 2021 to 374.0 million euro at 31 March 2022, up 12.0 million euro (+3.3%). The main contributions to this result came from the energy area, up by a total of 6.1 million euro, and the waste management area, up 8.1 million euro, offsetting the slight drop in the other services area. In particular, the activities managed concerning the ecological transition and circular economy were decisive, including energy efficiency services developed for condominiums, a reinforcement of value-added services in the energy sector (from “green” supply, to sales and installation of LED devices, smart boilers and thermostats, and energy diagnostics) and the regeneration of resources, through Group subsidiary Aliplast. Operating result and pre-tax profit down slightly Operating results amounted to 220.1 million euro at 31 March 2022, down 1.3% from the 223.1 million euro seen in the first quarter of 2021, mainly due to higher amortisation and depreciation due to changes in the scope of consolidation and higher provisions for bad debts mainly attributable to both last resort and traditional markets as well as the graduated protection service. Financial operations at 31 March 2022 were mainly unchanged, at 29.5 million, compared to 28.8 million euro seen in the first quarter of 2021. This change was caused by lower income from late payment indemnities, partially offset by lower financial charges on long-term debt resulting from debt optimisations. Pre-tax profit amounted to 190.6 million euro, slightly down from 194.3 million euro at 31 March 2021 (-1.9%). Net profit at 137.8 million euro Thanks to a tax rate coming to 27.7%, quite similar to the 27.8% rate of the previous year, net profit stood at 137.8 million euro, as against 140.3 million euro in the first quarter of 2021. Profit pertaining to the Group’s shareholders amounted to 126.5 million euro, down from 132.2 million euro at 31 March 2021, due to an increase in the portion attributable to minority shareholders. Strong growth in operating investments and Group solidity reinforced The Group’s operating investments, including capital grants, amounted to 129.2 million euro, up 11.1% compared to the previous year, and mainly involved work on plants, networks and infrastructures. In addition, regulatory upgrading was carried out, mainly in the gas distribution sector with a large-scale meter replacement, and in the purification and sewerage sector. Net financial debt went from 3,261.3 million euro at 31 December 2021 to 3,455.2 million euro at 31 March 2022, mainly due to a change in net working capital, which increased as a result of the energy scenario and the impact of interventions on “rising bills” also in terms of payment by instalments. The net debt/Ebitda ratio remained substantially stable, at 2.8x, confirming the company’s financial solidity. Profit & Loss (mln €) 31/03/2022 Inc.% 31/03/2021 Inc.% Ch.
