EBITDA stood at 317.0 million euro, up by 56.2%, compared with 203.0 million euro in 2024, while EBIT amounted to 178.2 million euro, compared with 63.3 million euro in the previous year.

These margins are also presented in an adjusted form which is more suitable to appreciate the trend of the normal business operations, with the exclusion of costs or revenues not representative of them; the main adjustments for the period are the neutralisation of i) the positive impact from the reconsolidation of the Russian subsidiary ("Ariston Thermo Rus LLC"), and ii) the negative impact of the PPA amortization related to past acquisitions, the strategic multi-year reorganization program and M&A expenses.

Adjusted EBITDA totaled 311.2 million euro, with a 11.5% margin on net revenue, compared to

276.3 million euro (10.5% margin) in 2024.

Adjusted EBIT amounted to 192.8 million euro, compared with 160.2 million euro in 2024, with 7.1% margin on net revenue, from 6.1% in 2024. The improvement was led by the execution of our efficiency initiatives and the positive impact of operating leverage, which more than offset the accelerated investments for growth in go-to-market, digital and R&D. The Group Net profit was equal to 132.4 million euro, compared with 2.5 million euro in 2024, while the Group adjusted Net profit was 112.9 million euro, from 89.0 million euro in 2024.

The Group adjusted Net profit is the result for the period attributable to the Group before adjustments on operating and financial income (expense), before the relevant taxation effect and before other positive/negative tax adjustments for the period.

Free cash flow reached 125 million euro in 2025, compared to 152 million euro in the previous year - when it benefitted from an exceptional net working capital reduction - thanks to profitable growth resulting in higher EBITDA contribution, continuous improvement in net working capital management, which more than offset higher CapEx in 2025 (141 million euro compared to 116 million euro in 2024), as planned. Net Financial Indebtedness on 31 December 2025 (calculated according to ESMA 32-382-1138 guidelines) decreased to 573.7 million euro from 602.7 million euro at 31 December 2024, thanks to cash flow generation partially offset by acquisitions, distribution payment, financial charges and buyback.

For comparative purposes, applying the calculation method used before the adoption of ESMA guidelines, Net Financial Indebtedness went from 579.1 to 542.0 million euro. The main differences are ESMA's inclusion - among liabilities - of put & call options related to acquisitions, and the neutralization of positive mark-to-market derivatives.
