The Board of Directors approves the Consolidated Results as of 31 December 2025

Milan, 18 March 2026 – The Board of Directors of Industrie De Nora S.p.A. (the “Company” or “De Nora”) – an Italian multinational company listed on Euronext Milan, specialized in electrochemistry and a leader in sustainable technologies – met on 17 March 2026 under the chairmanship of Federico De Nora, approved the Integrated Annual Report as of 31 December 2025, the Company’s Financial Statements draft as of 31 December 2025, and proposed the distribution of a dividend of euro 0.103 per share.

The Board of Directors also resolved to convene the Ordinary Shareholders’ Meeting in a single call on April 29, 2026 to resolve, among other items, on the approval of the Financial Statements 2025 and on the proposal for the allocation of the year’s earnings and the dividends distribution, the approval of the Report on the remuneration policy and on compensation paid, as well as the appointment of a member of the Board of Directors pursuant to Article 2386 of the Italian Civil Code.

Paolo Dellachà, Chief Executive Officer of Industrie De Nora, commented:

“2025 was another year of growth for De Nora: we achieved solid results, exceeded our operational profitability targets, and maintained a robust financial structure, confirming the resilience of our industrial model even in a particularly complex geopolitical context. This performance takes on even greater significance in light of the recent evolution of the energy and geopolitical landscape, particularly in the Middle East, where the safety of our people remains our priority and where, to date, no significant impacts on our activities have been recorded.

Over the course of the year, in addition to the continued development of our core businesses and the completion of two global flagship projects in green hydrogen, we entered two new markets: PFAS treatment within the Water Technologies business and the electrochemical refining of lithium within the Energy Transition business, opening a new growth stream linked to circularity.

Looking ahead, we are preparing to face a demanding year, marked by new and complex challenges. We do so with confidence: the work carried out in recent years has equipped us with the structure, skills, and determination needed to manage periods of uncertainty and volatility with discipline.

From a broader perspective, our medium‑to‑long-term strategy provides a clear direction: strengthening leadership in our core businesses, opening new markets through electrochemistry and water treatment technologies, and supporting growth both organically and through selected external development opportunities. These priorities will guide our actions in the coming months and support the journey of building an increasingly solid and resilient De Nora.”
