Notice to Shareholders
Interim Dividends Payment for the third quarter
of 2026
BRBI BR PARTNERS S.A. (“Company”)
informs its shareholders and the market in general that, at the Board of Directors Meeting held on November 3, 2026, the payment of interim
dividends to its shareholders (“Interim Dividends”) was determined and approved, based on the results for the Company’s
quarter ended September 30, 2026, in the amount of R$12,599,484.48 (twelve million, five hundred and ninety-nine thousand, four hundred
and eighty-four reais and forty-eight centavos).
| i. | Dividend Amount per Share: the aggregate amount of R$12,599,484.48 (twelve million, five hundred
and ninety-nine thousand, four hundred and eighty-four reais and forty-eight centavos) corresponding to R$0.04 (four centavos) per common
or preferred share of the Company. Shareholders holding UNITs (BRBI11), consisting of 1 (one) common share and 2 (two) preferred shares,
will therefore receive the equivalent of R$0,12 (twelve centavos) per UNIT. |
| ii. | Ex-Dividend Declaration and Trading Date: The dividend payment will be made to the shareholders
registered in the Company’s records on November 12, 2026, considering trading up to and including that date. The shares issued by the
Company will be traded ex-dividend from and including November 13, 2026. |
| iii. | Payment Date: The dividends will be paid in a single installment on November 26, 2026, in Brazilian
Reais, and there will be no monetary restatement or interest accrued between the dividend declaration date and the actual payment date.
On the dividend payment date, the Company will credit the amount due to each shareholder, according to the number of UNITs (BRBI11) held
on the base date of November 13, 2026 (inclusive), to the respective account and bank domicile provided by such shareholders’ broker to
B3 S.A.- Brasil, Bolsa Balcão, and transferred to BTG Pactual Serviços Financeiros S.A. DTVM, the institution responsible
for the bookkeeping of the Company’s UNITs. |
