4. AGENDA AND RESOLUTION: After examining the matters on the Agenda, the members of the Board of Directors unanimously decided as follows:

4.1. Proposal for the Declaration of Interest on Capital: The proposal for a declaration of interest on capital by the Company (“IoC”) was approved, based on the balance sheet of March 31, 2026, in the gross amount of R$365,000,000.00, corresponding to R$301,125,000.00^[1] net of withholding income tax. The gross amount of IoC per share is equivalent to R$0.11421932485^[2], of which R$0.09423094300¹ ² net of income tax.

The IoC credit will be carried out individually to the shareholders, based on the shareholding position in the Company’s records at the end of April 27, 2026. After this date, the shares will be considered “ex-IoC”.

The net amount of the IoC will be allocated to the mandatory minimum dividend for fiscal year ending December 31, 2026, ad referendum to the Ordinary General Meeting to be held in 2027, and the payment of these proceeds will be made by April 30, 2027, with the Company’s Management being responsible for setting the exact date.

^[1] Considers the standard tax rate of 17.5%, which may vary due to international treaties, tax immunities and exemptions, countries with favorable taxation, and privileged tax regimes.

^[2] Value per share calculated based on the shareholding position of March 31, 2026. Given the Company’s Share Buyback Program in effect, the value per share may be subject to change, considering the Company’s shareholding position to be verified on April 27, 2026.
