As established in article 26 of the Company’s Bylaws, said IoC will be considered as part of the mandatory dividends for the fiscal year ending on December 31, 2026, ad referendum of the Ordinary General Shareholders’ Meeting to be held in 2027.

The IoC will be paid individually to each shareholder, based on the shareholding position in the Company’s records at the end of June 26, 2026. After this date, the shares will trade as “ex-IoC”. The payment of these proceeds will be made by April 30, 2027, with the Company’s Executive Board being responsible for setting the exact date.

The amount per share of the IoC may be adjusted considering the Company’s shareholding base on June 26, 2026, due to possible acquisitions of shares under the Company’s ongoing Share Buyback Program. In the event of share repurchases, the Company will disclose a Notice to the Market informing the recalculated amount per share. If no share repurchases occur during the respective period, the information contained in this Notice shall remain valid, and no additional Notice to the Market will be issued to confirm the amount per share.

² Amount per share calculated based on the shareholding position of May 29, 2026.
