The first nine months of the year closed with strong growth in revenue and investments, and with all key operating and financial indicators positive, in line with the first two quarters and the targets set out in the Business Plan

Operating and financial highlights
- Revenue rises to 9,365.6 million euro (+10.6%)
- EBITDA stable at 1,037.2 million euro
- Net profit for the period up to 324.6 million euro (+4%)
- Gross operating investments at 666.8 million euro (+18.8%)
- Net financial position at 4,147.2 million euro and net financial position/EBITDA ratio at 2.6x, an improvement compared to September 2024
- Return on invested capital increases, with ROI at 9.9%
Key industrial guidelines
- Organic growth of the multi-business portfolio. The strong performance of the water and waste sectors offsets the absence of the temporary opportunities seized in 2024 within the energy segment.
- Expansion of the operational scope. Strengthening continues through M&A and joint venture initiatives (Ambiente Energia, CircularYard) and through the full consolidation of subsidiaries EstEnergy, Hera Comm, and Aliplast via the acquisition of minority interests.
- Value creation capacity. Solid operating performance and efficient financial management support earnings growth and the profitability of invested capital.
- Ample room for development. Cash generation and financial flexibility provide the basis for new organic and external growth initiatives, consistent with the objectives of the Business Plan.
Today, the Hera Group’s Board of Directors, chaired by Executive Chairman Cristian Fabbri, unanimously approved the consolidated quarterly report at 30 September 2025, which confirms a positive structural performance and strong growth in revenues and investments compared to the same period of the previous year.
Cristian Fabbri, Executive Chairman of the Hera Group:

“Over the past nine months, leveraging cash generation and our strong financial flexibility, we have focused on the Group’s structural growth: we have doubled our operating investments aimed at development, increasing investments by almost 20% in both regulated sectors and free-market businesses. We furthermore completed a number of M&A transactions and repurchased the minority stakes in EstEnergy, Aliplast and, at the beginning of October, Hera Comm, all of which are now 100% owned. These persistent growth drivers, combined with the strength of our multi-business portfolio, enabled us to offset the loss of certain temporary opportunities and resulted in an increase in return on equity, now close to 10%. These results demonstrate that we are fully on track to achieve the objectives set out in our Business Plan.”
Orazio Iacono, CEO of the Hera Group:
“Strong operating performance and steps towards financial optimisation supported growth in net profit attributable to Shareholders, which rose by 4.2%. The macroeconomic scenario remains complex, but signs of stabilisation in the energy market, combined with our ability to generate cash flow and margins – with the net debt/EBITDA ratio at 2.6x – now allow us to pursue development opportunities with even greater momentum. One non-negotiable principle remains at the heart of our industrial strategy: sustainability must go hand in hand with competitiveness. All our investments in technologies and services aim to strengthen this connection, improving resilience, innovation and the quality of our offer. Only in this way can we reconcile the Net Zero 2050 target with the growth of local areas and the well-being of communities.”
Double-digit growth in revenue, at 9.4 billion euro
At 30 September 2025, the Hera Group’s revenue amounted to nearly 9.4 billion euro (9,365.6 million euro), increasing by more than 894 million euro compared to the same period in 2024, up +10.6%, mainly linked to the increase in energy commodity prices and the higher value of gas and electricity volumes traded.
EBITDA stable at 1,037 million euro
EBITDA for the first nine months of 2025 remained substantially stable with respect to the previous year, amounting to 1,037.2 million euro. Lower margins in the energy areas (–23.3 million euro) were offset by positive results in the water cycle and waste management services. The comparison with 2024 should however take into account the 85 million euro in extraordinary margins recorded that year, linked to temporary non-recurring opportunities (mainly last resort markets and eco-bonuses). Adjusted for these effects, EBITDA at 30 September 2025 shows structural growth coming to 9%, supported by contributions from all the Group’s core businesses, exceeding the 7% average annual growth rate forecast in the Business Plan for the period to 2028.
Profit before income tax above 457 million euro
Ebit for the first nine months stood at 519.9 million euro, down slightly (-0.5%) compared to the same period in 2024, mainly due to the increase in depreciation and amortisation linked to new investments in regulated sectors and waste treatment, while provisions decreased thanks to the normalisation of the energy market. Effective operational and financial management, which saw a 27.5 million euro reduction in expenses thanks to a rationalisation of the debt structure and a reduction in IAS expenses, led to a profit before income tax of 457.2 million euro, up 5.5% compared to the 433.5 million euro seen at 30 September 2024.
Net Profit up 4%
Despite the increased tax rate, at 29% (vs 28% the previous year), net profit at 30 September 2025 reached 324.6 million euro, up 4% compared to 312.1 million euro in the same period of 2024. At the same time, net profit attributable to Group Shareholders also grew, reaching 294.7 million euro (+4.2% compared to 282.9 million euro at 30 September 2024).
Strong growth in operating investments and confirmation of the Group’s financial solidity
At 30 September 2025, operating investments, including capital grants (34.2 million), amounted to 666.8 million euro, up by almost 106 million compared with the same period in 2024 (+18.8%). The areas that benefited most from development and regulatory compliance measures were the integrated water cycle (over 243 million euro in investments, 68 million euro more than the figure seen at 30 September 2024), the waste management area (almost 30 million euro more over one year) and the gas area (+11 million).

Eni and Hera together for the circular economy: from spent vegetables oils the biofuel for waste collection vehicles
The partnership will make it possible to transform the Eni bio-refinery in Venice into oils collected by Hera (800 tons in 2017) in Eni green diesel. Relevant environmental benefits with a reduction of up to 40% of polluting emissions

Eni and Hera, companies long engaged in promoting a circular economy model through the continuous technological and organizational development of their respective businesses, have today signed a partnership aimed at transforming used vegetable oil into biofuel to fuel the Hera waste collection company vehicles.
The agreement provides that exhausted vegetable oils for domestic use, such as those for frying, recovered by Hera through approximately 400 road containers and in about 120 collection centers, will be sent to the Eni biorefinery in Venice, in Porto Marghera, the world's first example of conversion of an oil refinery into a biorefinery, which will transform it into green diesel, a completely renewable product which constitutes 15% of Enidiesel +. The biofuel will feed the Hera company vehicles for the collection of urban waste. In the experimental phase Enidiesel + will be used by some thirty large vehicles, in order to optimize the environmental benefit, in the Modena area.
The agreement signed today extends the virtuous circle already initiated by Eni with the multi-utility companies of Turin, Venice and Rome and whose tests have already demonstrated important benefits in terms of air quality, economic and industrial. In fact, compared to traditional diesel, Enidiesel + has a renewable component that reduces polluting emissions by up to 40%, saves fuel consumption by around 4% and reduces engine maintenance costs. The same technical improvement parameters deriving from the use of the biofuel will be subject to joint monitoring by the two companies, in collaboration with the CNR Institute of Motors.
To further support the initiative, Hera has chosen to enhance the collection of vegetable oils by introducing 300 new dedicated containers in the areas served. In 2017 alone, 800 tons of waste vegetable oils were collected, recovered and then processed to be valued as lubricants or through energy recovery. An increasingly widespread service which, by encouraging correct recovery, also aims to prevent behavior, such as the spillage of oils in the sink, which is harmful to domestic pipes and water purification plants.
