Press Releases and Notices

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 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.

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 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.

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.

By acquiring this Veneto-based company, the Hera Group has further consolidated its leadership in the waste management sector. From this and two similar transactions completed in the first half of 2021 in the industrial waste treatment sector, a consolidated contribution to Hera’s Ebitda coming to 20 million euro is expected The Hera Group has further strengthened its national leadership in the waste management sector, more specifically in industrial waste treatment. The Group, through its subsidiary Herambiente, has in fact acquired 80% of the Vallortigara Group, which provides services to industries, public administrations and citizens and manages a multifunctional platform for special waste treatment in Torrebelvicino (Province of Vicenza in the North-Eastern part of Italy). The Torrebelvicino platform consists of three sections: a storage and selection plant for solid and liquid, hazardous and non-hazardous industrial waste, a stabilisation and solidification plant for industrial sludge and a chemical-physical plant for liquid waste. Currently, this facility treats approximately 75,000 tonnes of waste per year and, thanks to the investments planned by Herambiente, it will be able to increase and streamline its activities, in line with the principles of the circular economy. The acquisition of the Vallortigara Group, which employs over 100 workers and has 4,000 customers,both in public and private sector, will enable the Hera Group to strengthen its presence in the Triveneto region. It will also expand its service to neighbouring territories, creating significant synergies with the Hera Group’s industrial centres in the provinces of Pisa and Ravenna, which have been operational for some time. The current owners (the Vallortigara family) will remain within the new corporate structure. Overall, through the company Hasi (Herambiente Servizi Industriali), Herambiente now has 18 multi-purpose sites dedicated to treating waste produced by businesses, with 1.3 million tonnes of industrial waste treated each year. Following the two transactions in the same field, industrial waste treatment, carried out in the first half of 2021 – the acquisition of 70% of the company Recycla in Friuli and 31% of the company SEA in the Marche region – Herambiente’s development plan thus continues, confirming its position as the country’s leading operator in the sector, able to provide across-the-board solutions in industrial waste treatment to an increasing number of new customers. In fact, all the acquisitions made by Herambiente also contribute to the objective of strengthening the geographical presence by increasing the penetration at local level, thus improving the efficiency and quality of services to local businesses and generating positive returns in the areas served, along with economic benefits for customers. “This new transaction is in line with the significant path of strategic development we are implementing in the industrial waste sector”, comments Tomaso Tommasi di Vignano, Executive Chairman of Hera Group. “When fully operational, thanks to the three acquisitions made in 2021, we will treat more than 300,000 additional tonnes of industrial waste produced by 3,300 new industrial customers every year, with a contribution to the Hera Group’s Ebitda coming to roughly 20 million euro, in addition to the value of the synergies expected from the integrations.” Press releaase Vallortigara acquisition.pdf 2021-09-13 11:02:00 Sede Gruppo Sede Gruppo 2019-07-03

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