² Cash flow from Operating Activities: Reported EBITDA + change in Net Working Capital – Income Taxes.

¹ The difference between Adjusted EBITDA (Adj.) and Reported EBITDA in the preliminary data as of December 31, 2025, amounts to approximately €7.7 m and includes non-recurring personnel costs of €0.9 m, non-recurring M&A and company reorganization costs of €4.5 m, non-recurring costs related to the disposal of the Marine Technologies business and the Fracking business line amounting to €2 m, and other non-recurring costs of €0.6 m, partially offset by income of €0.3 m related to the net value between eligible IPCEI GF costs and the related contributions.

{1}------------------------------------------------

financial full-year results will be approved by the Board of Directors on 17 March 2026 and published on 18 March 2026 before market opening.

Paolo Dellachà, Chief Executive Officer of De Nora, commented: "The preliminary results for 2025 confirm the soundness of our growth trajectory and the quality of our execution: we recorded increasing revenues and margins, with an adjusted EBITDA margin above guidance, supported by solid operating cash flow generation. Results were driven by the Energy Transition and Water Technologies businesses. The latter benefited from significant growth in Pools and solid order intake development in the Water Technologies Systems.

In the Energy Transition business, in 2025 we delivered approximately 1.1 GW of technologies for green hydrogen, dedicated to two major flagship projects at a global level developed over the past two years: NEOM in Saudi Arabia (2.2 GW) and Stegra in Sweden (over 700 MW), substantially completed in the fourth quarter. These projects have positioned us as a global leader in the supply of advanced AWE technologies.

At the same time, we are expanding the scope of our applications in high-growth-potential markets, such as lithium refining and recycling, and solutions for PFAS removal. These initiatives reflect a strategy aimed at pioneering new industrial trends and leveraging our electrochemical leadership in value chains that are critical for resource security and environmental sustainability.

2026 is expected to be a challenging year, marked by limited visibility in the green hydrogen market and a potential temporary slowdown in the Electrode Technologies business, linked to the macroeconomic environment and the cyclical nature of investments. For the Water business, we expect a continuation of the development already started in 2025. In this context, we continue to rely on a flexible business model, a solid technological base and a diversified global presence, while also evaluating targeted actions to mitigate the impact of lower cost absorption due to a temporary potential decline in volumes.

We look to the medium term with confidence: all our sectors present solid fundamentals and, in addition to the expected growth in Water and the progressive development of the hydrogen market, we also see significant opportunities in new business areas. We are also actively evaluating external growth opportunities, with a particular focus on the water treatment systems business, to further strengthen our strategic positioning."

As of 31 December 2025, preliminary revenues amounted to about euro 875.0 million, up 1.4% compared to the 2024 figure (euro 862.6 million). The figure was negatively impacted by approximately euro 25 million due to the performance of certain currencies, particularly the Euro–Dollar exchange rate. Net to these effects, growth would have been 4.4%.

The revenue trend, consistent with the guidance provided for the fiscal year, mainly reflects growth of 6.4% in the Energy Transition business and 7.2% in the Water Technologies business, partially offset by a 3.6% decline in the Electrode Technologies business, which, net of the negative exchange-rate impact of approximately euro 13 million, would have been broadly stable compared with 2024.

Revenues by business. The Electrode Technologies business reported revenues of approximately euro 437.1 million, compared to 453.3 million of 2024. The performance mainly reflects the recovery of the Electronics line, which reported growth of around 10.4% compared to 2024, and the overall stability of the Chlor Alkali line, offset by a decline of roughly 28% in the Electrowinning and Specialties line, which was impacted by the interruption of a project with a Russian customer that had contributed to the previous year's results. Aftermarket revenues accounted for 46%.

The Water Technologies business reported revenues of about euro 326.0 million, up 7.2% from euro 304.1 million in 2024. Net of the negative impact of certain exchange rates, particularly on the Euro–Dollar, growth would have been 11%. The business performance reflects the expansion of the Pools line, which recorded revenues of approximately euro 125.8 million, an increase of 27.5% year‑on‑year.

The Water Technologies Systems ("WTS") line reported revenues of approximately euro 200.2 million, compared with euro 205.4 million in 2024, with aftermarket revenues accounting for 42% (38% in 2024). The figure was negatively impacted by approximately euro 7 million due to the performance of certain currencies,

{2}------------------------------------------------

particularly the Euro–Dollar exchange rate, and by the change in scope following the disposal of the Marine business, which accounted for euro 4.5 million. Net of these effects, the WTS line would have reported revenue growth of 3% compared to 2024. It should be noted that during the year the WTS order backlog increased by 8%, providing strong visibility on the evolution of the business over the coming quarters.

The Energy Transition business reported revenues of approximately 111.9 million (105.2 million in 2024), up 6.4% year-on-year. During 2025, De Nora realized 1.1 GW of green hydrogen technologies, bringing the cumulative total of technologies produced since 2022 to 3.5 GW. The business' expansion mainly reflects the good execution of the projects in backlog. In particular, during 2025 the Company completed deliveries for two major contracts: the NEOM project in Saudi Arabia, the world's largest green hydrogen plant with a capacity of approximately 2.2 GW, completed by the third quarter, and Stegra in Sweden, one of Europe's leading projects to produce hydrogen for green steel, with a capacity of over 700 MW, substantially completed during the fourth quarter. As of 31 December 2025, the business' backlog amounted to euro 19.3 million, including the project related to lithium recycling from end-of-life batteries for a Japanese customer.

The adjusted EBITDA as of 31 December 2025 amounted to approximately euro 171.8 million, up 9.1% compared to 2024 (euro 157.4 million); the adjusted EBITDA margin was around 19.6%, an increase of over 1 percentage points versus 18.2% reported in 2024 and above the guidance provided for the year, supported by the positive performance of the Water Technologies and Energy Transition business.

Adjusted EBITDA margin by business. The Electrode Technologies business reported an adjusted EBITDA margin of 20.1% (22.4% in 2024). The evolution compared to the previous year reflects a different mix of projects in backlog, also due to the decline in the Electrowinning product line. The Water Technologies business reported an adjusted EBITDA margin of 21.1%, up about 5 percentage points from 16.5% in 2024, mainly due to the expansion of the Pools line and the aftermarket revenue increase of the WTS line. Finally, the Energy Transition business recorded a positive profitability of 13.7%, strongly increasing compared to 5.3% of 2024, thanks to the significant recovery of operational efficiency achieved following targeted investments to improve the production set-up made in previous years.

As of 31 December 2025, the Net Financial Position was positive with net cash of approximately euro 87 million, up by about 20 million compared to 67.1 million of 31 December 2024, thanks to the excellent operating cash flow generated, amounting to approximately euro 115 million, which funded investments (around euro 78 million), also more than covered the dividend distribution (euro 20.7 million).

Guidance 2026.

For 2026, the Company expects Revenues in the range of euro 750 – 850 million. The guidance primarily reflects the uncertainty surrounding the timing of certain projects within the Energy Transition pipeline particularly those linked to the green hydrogen market, which is currently experiencing a slowdown and limited visibility — thereby reducing the predictability of expected 2026 revenues.

The range also factors in a temporary slowdown in 2026 in the Electrode Technologies business, influenced by the macroeconomic and geopolitical environment and by the cyclical dynamics of plant renewal. Conversely, the Water business is expected to deliver mid-single-digit growth, supported by solid Pools performance and robust WTS backlog.

In this context, and in light of the expected revenue dynamics, the Company forecasts an Adj. EBITDA margin for 2026 in the range of 15% to 18%.

While maintaining its commitment to research activities, aimed at developing innovative solutions and continuously improving its technologies, De Nora is actively evaluating measures to mitigate the lower absorption of fixed costs resulting from lower volumes and the consequent impact on operating profitability.

De Nora will provide further details on the 2026 Guidance on March 18, in conjunction with the publication of the final 2025 results. On the same occasion, the Company will present an update of its Mid-Term View, taking into
