The Hera Group’s Board of Directors, chaired by Executive Chairman Cristian Fabbri, has reviewed the 2025 preliminary results and approved the Business Plan to 2029.
Cristian Fabbri, Executive Chairman of Hera Group:

“The new Business Plan confirms our commitment to creating value for all stakeholders. The 5.5 billion euros investment plan, up by around 40% compared to the last five years, supports, also through innovation, sustainable industrial development and the increased resilience of our infrastructures and will allow us to target an EBITDA of 1.76 billion euros by 2029. The improvement in the objectives of the new Business Plan and the positive economic and financial forecasts for the 2025 results allow us to revise the dividend policy upwards by proposing an increase of approximately 7% already from the next dividend, up to 27% in 2029 with a dividend of 19 eurocents per share. The economic value distributed over the 5 years to stakeholders in the areas in which we operate and the contribution of sustainable activities to the Group's EBITDA, which will reach 68%, are also growing to 11.5 billion euros.”
Orazio Iacono, CEO of the Hera Group:
"We expect to close 2025 with an EBITDA of more than 1.53 billion euros and a profit attributable to shareholders of more than 0.46 billion euros. Results supported by the growth of all businesses in the portfolio, despite the absence of temporary opportunities that had been seized in 2024. This performance made it possible to finance an increase in capital expenditures while maintaining a net debt/EBITDA ratio of less than 2.6x. This financial flexibility allows us to support investments in the green transition and industrial development. The capital expenditures, earmarked for both regulated and liberalised businesses, will fuel organic growth and will be financed by strong cash generation, which will allow us to maintain a financial leverage in 2029 in line with that of the expected closure in 2025, reconfirming financial soundness and creating additional flexibility to be able to seize future new opportunities".
BUSINESS PLAN TO 2029
Development, resource regeneration, carbon neutrality, resilience and the creation of tangible and sustainable value for the benefit of all stakeholders are reconfirmed as the strategic axes of the new Plan, which also leverages innovation and digitalisation to support the achievement of the Group’s environmental, social and economic objectives. The increasing investments planned over the five-year period, mainly earmarked for development, will also make it possible to further strengthen the assets managed, also to cope with the increasing frequency of extreme weather events related to climate change.
Value creation with the aim of reaching 1.76 billion euros of EBITDA by 2029 with a net profit attributable to Shareholders growing to approximately 520 million euros
The Plan's projects promote structural growth of approximately 350 million euros with an average annual growth rate of around 5%. This growth more than offsets the loss of approximately 180 million euros in non-recurring business opportunities (compared to 2024) and achieves a total EBITDA of 1,760 million euros by 2029, up by 60 million euros compared to the previous Plan target for 2028.
Organic development, which contributes approximately 250 million euros, is the main lever and is fuelled by the development capex plan, both in regulated and liberalised businesses, by commercial development and by the continuous search for efficiencies. Organic growth is also supported by innovative technologies and plant solutions and the use of artificial intelligence.
Focus on sustainable development with a constant growth of shared-value EBITDA, equal to 68% of total EBITDA
The Hera Group has planned initiatives with adequate profitability, consistent with the economic and financial balance and which, in parallel, guarantee to amplify the creation of sustainable value.
Keeping the focus on decarbonisation, circular economy, resilience and innovation, an important evolution of the EBITDA at shared value is expected, which in 2029 will reach 68% of the Group's EBITDA. Over the five-year period, the shared-value EBITDA will increase by 30%, reflecting the growing weight of initiatives that, in addition to contributing to the development of the company, are in line with the objectives of the UN Agenda and with the development of the territory and communities.
Gross investments of 5.5 billion euros with an expected leverage of 2.6x in 2029
During the period 2025-2029, the Business Plan foresees gross investments of 5.5 billion euros, a financial commitment 6% higher than the previous strategic document and 39% higher than the total resources invested in the last 5 years. In addition to the 5 billion euros of investments directly financed by the Hera Group, there are almost 500 million euros of contributions from the National Recovery and Resilience Plan (NRRP) resources and other institutions (PNIISSI, FONI, etc.).
Regulated businesses will absorb 63% of the investment plan (with 3.1 billion allocated to networks, which are confirmed as the most capital-intensive business), while the remaining 37% will fuel the growth of liberalised businesses. Most of the investments (55% or 3 billion) will be for development, while the remaining 2.5 billion will be for maintenance.

Hera Group acquires Sostelia and becomes Italy’s leading player in water treatment
With this integration, the multiutility further strengthens its positioning also in the industrial and civil water treatment sector

Hera Group further strengthens its leadership in the environmental sector, in particular in the treatment of civil and industrial water, thanks to the binding agreement signed for the purchase of 100% of STA and the related stakes in the subsidiaries that are part of the Sostelia Group (NTW, CID, NPC, Trentino Acque, COMS, Acque della Concordia, Arcobaleno GC). Sostelia is an important Italian private player for technologies and the treatment of industrial and civil water, 65% controlled by Xenon Fidec, an impact private equity fund managed by Xenon AIFM, and with the remaining 35% held by entrepreneurs representing the companies within the group.
The transaction has an enterprise value of €138 million. The acquisition by Hera Group is subject to certain customary closing conditions (including notifications and approvals by the competent authorities) and is expected to be completed by the end of March 2026.
Once fully integrated, the transaction is estimated to contribute more than €20 million to the consolidated EBITDA growth of Hera Group, in addition to the value of the expected integration synergies.
The strategic lines of the transaction
The transaction creates a benchmark player in Italy with an integrated offering in the water treatment market - from design and construction (EPC) to operation and maintenance (O&M), up to the treatment and disposal of liquid waste and sludge related to purification processes. It also enables a strong system of synergies with Herambiente, the Hera-controlled subsidiary and Italy’s foremost environmental operator, enhancing quality, efficiency, and service continuity for both public and private customers.
Synergies are, in fact, one of the main drivers of value creation. On the one hand, the integration of Sostelia’s services could enable Herambiente to broaden its commercial offering by providing its customers with additional services such as revamping solutions and the design of new plants, or the operation and maintenance of existing private plants, ensuring technical-operational continuity that translates into greater reliability and lower operating costs. On the other hand, Sostelia’s customer portfolio represents a significant opportunity for Herambiente to integrate its own service offering.
More generally, the combination of Sostelia’s technical expertise, plant infrastructure, and commercial capability will enable Hera Group to expand its customer base, diversify revenues, and increase business resilience in a sector that requires speed of intervention, high quality of service, and continuous innovation.
