SHARE CAPITAL AND SHARES WITH VOTING RIGHTS

Pursuant to Article 125-quater of the Consolidated Law on Finance, it should be noted that, as of the date of this notice of call, the Company's subscribed and paid-up share capital amounted to Euro 18,268,203.90, divided into 201,685,174 shares, without any indication of par value, of which no. 51,203.979 ordinary shares listed on Euronext Milan, organised and managed by Borsa Italiana S.p.A., and no. 150,481,195 shares with multiple voting rights, not subject to listing, as provided for by Article 5 of the By-Laws, available on the Company's website www.denora.com (Section

"Governance / Documents and Procedures"). Each ordinary share entitles the holder to 1 (one) vote in the Company's ordinary and extraordinary shareholders' meetings, while each multi-voting share entitles the holder to 3 (three) votes in the Company's ordinary and extraordinary shareholders' meetings.

As of the date of this notice, the Company holds 2,986,240 treasury shares, corresponding to 1.48% of the share capital, for which voting rights are suspended pursuant to law.

Since the Company's By-Laws provide for the issuance of shares with multiple voting rights pursuant to Article 127-sexies of the Consolidated Law on Finance, the Company shall disclose to the public, pursuant to Article 85-bis, paragraph 4-bis, of the Issuers' Regulations adopted by CONSOB with resolution No. 11971 of 14 May 1999, as subsequently integrated and amended (the "Issuers' Regulation"), the total amount of voting rights by the day following the date indicated in Article 83 sexies, paragraph 2, of the Consolidated Law on Finance (the "record date") and, therefore, by 17 April 2025.

RIGHT TO INTERVENE AND VOTE

The right to attend the Shareholders' Meeting and exercise voting rights - which will only occur through the Designated Representative - is certified by a notice sent to the Company by the authorized intermediary, at the request of the entitled party, on the basis of the accounting records relating to the end of the accounting day of the seventh trading day prior to the date set for the Shareholders' Meeting on a single call, i.e. Wednesday 16 April 2025 (record date). Those who result as holders of the Company's shares only after that date, based on the recordings made in such accounts, will not be entitled to attend and vote at the Shareholders' Meeting and, therefore, will not be able to issue a proxy to the Designated Representative. The notice from the intermediary must reach the Company by the end of the third trading day prior to the date set for the Shareholders' Meeting and, therefore, by 24 April 2025. However, the legitimacy to attend and vote, again exclusively through the Designated Representative and in compliance with the terms for granting proxies to the Designated Representative, remains unaffected if the communications are received by the Company after the aforementioned deadline, provided that they are received before the start of the Shareholders' Meeting activities.
