The Hera Group closed the year 2021 with positive results, despite the complex scenario seen in Italy due to the ongoing Coronavirus emergency and, in the second half of the year, high volatility in the energy market. Thanks to its solid and efficient multi-business model and its good operational, financial and fiscal management, Hera managed to keep its results growing while pursuing sustainable development. It also succeeded in supporting its stakeholders, first and foremost its customers, with concrete actions such as bill instalment plans to enable them to meet their payments. More generally, the Hera Group prolonged the path of uninterrupted growth that has characterised it since it was founded in 2002, continuing to leverage its own strategy: a balanced mix of internal and external growth, with significant economies of scale and an extraction of synergies that exceed expectations. All this was accompanied by a wide range of initiatives for the energy transition, the circular economy and technological evolution, consistent with the path set out in the Business Plan to 2025, which aims to stand beside local areas in recovery, while respecting European strategies and the goals of the UN’s 2030 Agenda. “In 2021 our commitment to pursuing the creation of value for the company and our stakeholders, with sustainable development, once again enabled us to achieve positive results and implement actions to support the environment in which we operate, starting with our customers. We will continue to do so in spite of the current scenario, which remains complex, and we look to the future by focusing on two factors that have always distinguished our twenty-year history: concreteness and solidity. Our decision to increase the dividend to 12 cents per share, in line with what we announced when we presented our new Business Plan, is a step in this direction and will benefit our shareholders, who will be able to count on higher income to face the current difficult situation. Risk prevention and management, moreover, is one of the strategic guidelines underpinning our Plan; it translates into the medium- to long-term approach required to anticipate actions and thus offset the risks to which utilities are exposed, deal with complexities and continue to guarantee service quality and continuity”. Executive President, Tomaso Tommasi di Vignano, went on to say at the end of the Board of Directors meeting of 23 March. Chief Executive Officer, Stefano Venier, added: “The positive results achieved in 2021 show a further reinforcement of the company’s financial solidity, confirmed among other things by the net debt/Ebitda ratio, now at 2.66x, an improvement compared to the previous year. The positive cash flow allowed us to make greater investments, with positive repercussions for the areas in which we operate, in terms of both service quality and the induced economic activity created. Our greater solidity allows us to face the current complex scenario with confidence, continuing to guarantee investments and support for our stakeholders, with sustainability fully integrated into our business strategies. This is confirmed by the increase of over 25% in shared value Ebitda, which rose to 570.6 million in 2021 and accounted for 46.6% of total Ebitda, with the aim of reaching 70% in 2030”.

This prize has been assigned over the last ten years following an analysis of the main companies in the water, energy and waste management sectors, carried out by a research team from Althesys, a consultancy firm specialising in the public utility sector. The award ceremony was held during an online event entitled “Digitalization and sustainability for the future of Italian utilities”.

Business Plan to 2025 A Plan that combines growth, value creation and sustainable development Today, the Hera Group’s Board of Directors approved the Business Plan to 2025, which consolidates the Group’s commitment to balanced and sustainable development in all business areas, with the aim of continuing to create value for shareholders, local areas and the communities served. With Ebitda expected to reach 1.4 billion in 2025 and investments totalling approximately 3.8 billion over the period covered by the Plan, this five-year strategic document shows increases in all main targets and outlines a wide range of actions for the energy transition, the circular economy and technological evolution, with concrete and innovative projects that will also benefit from funding opportunities coming from the Recovery and Resilience Plan. 20 years of uninterrupted growth, and 2021 Ebitda expected to total over 1.2 billion euro The new Plan is based on a trend of uninterrupted growth, as is proven by Group Ebitda, which has increased more than sixfold in 20 years. This consistent and linear path has been seen since the establishment of the Hera Group, which is characterised by a full correspondence between the commitments made and the initiatives implemented, capital and financial solidity and a multi-business strategy that balances regulated and free market activities, internal growth and M&A transactions. This model, which has proved its resilience and capability of supporting stakeholders, even during adverse scenarios, has enabled the Hera Group to consolidate leading positions in all business areas. Three focal points of the Business Plan to 2025: environment, socio-economic factors and innovation In a context undergoing recovery, with an increasing emphasis on sustainability and the utilities sector set to benefit from the most significant share of the Recovery and Resilience Plan, the Hera Group will be able to continue to leverage the competitive position it has cultivated over the years and thus grow. In full compliance with national and European policies and the objectives on the UN’s 2030 Agenda, which have been guiding Hera’s strategies for some time, all projects in the Business Plan to 2025 are structured around three focal points: the environment, socio-economic factors and innovation, with initiatives for the green and digital transition, capable of generating positive effects in the areas served. A strong increase in investments, coming to over 3.8 billion euro, thanks to the Group’s financial solidity The Plan to 2025 calls for a sharp increase in investments, amounting to more than 3.8 billion euro, or approximately 770 million per year. This is a very significant rise – equivalent to 60% – compared to the average seen over the last five years, and is possible thanks to its solid financial structure, reinforced over the years and in 2021 as well. Investment allocation combines internal development opportunities with actions to increase system resilience (accounting for roughly 1.2 billion). Significant investments for innovation will be made in all business areas and support will be given to the ongoing transition. In general, of the total investments envisaged in the Plan, more than 1.7 billion are aligned with the criteria with which the European Taxonomy identifies opportunities that contribute to environmental policy objectives, in particular the two areas regulated for now, relating to mitigation of and adaptation to climate change. Furthermore, many of these interventions respect the directions indicated by the Recovery and Resilience Plan.
