**<u>Annex I</u>**

**Trading of Company´s Own Shares**

**Banco Santander (Brasil) S.A.** (the "Company" or "Santander"), pursuant to the provisions of Article 33, item XXXV, of CVM Resolution No. 80, of March 29<sup>th</sup>, 2022, hereby informs its shareholders and the market that the Board of Directors approved on September 25, 2025, a Buyback Program to purchase shares issued by the Company, as follows:

**1. Justify in detail the purpose and expected economic effects of the operation.**

The buyback program purposes are: (1) to maximize the value creation to shareholders by means of an efficient capital structure management; and (2) to enable the payment of officers, directors, management level employees and other employees of the Company and companies under its control, in accordance with the Long Term Incentive Plans.

**2. Inform the number of (i) outstanding shares and (ii) shares already held in treasury.**

On December 31<sup>st</sup>, 2023, Banco Santander had: (i) 348,147,839 outstanding common shares and 375,952,252 outstanding preferred shares; and (ii) 27,291,697 common shares and 27,291,697 preferred shares in treasury.

**3. Inform the number of shares that may be purchased or sold.**

The buyback program shall cover the purchase of up to 37,463,477 Units, representing 37,463,477 common shares and 37,463,477 preferred shares, or ADRs, corresponding, on December 31<sup>st</sup>, 2023, to approximately 1% of the Company´s total capital stock, to be purchased by the Company or by its branch in Cayman, being certain that the effective buyback of the total number of shares just established shall observe, at the acquisition moment, the limit set forth on Article 9 of CVM Resolution 77.

**4. Describe the main characteristics of the derivative instruments that the company may use, if any.**

There will be no use of derivatives as part of the Buyback Program.

**5. Describe, if any, eventually existing agreements or voting instructions between the company and the counterparty of the operations.**

The shares' purchase will take place by means of operations on the stock exchange and therefore there is no existing agreements or voting instructions between the Company and the counterparties of the operations.

**6. In case of transactions carried out off the organized securities markets, inform:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a. the maximum price (minimum) by which the shares will be purchased (sold); and**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b. if applicable, the reasons that justify operations at prices more than 10% (ten percent) higher, in case of purchase, or more than 10% (ten percent) lower, in case of sale, than the average market price, weighted by volume, within ten (10) prior trading days.**

![](bsbr202509256k_001.jpg)

All operations shall be carried out on organized markets. The Units shall be purchased on the B3 S.A. Brasil, Bolsa, Balcão ("B3"), through Santander Corretora de Câmbio e Valores Mobiliários S.A., and ADRs shall be purchased on the New York Stock Exchange ("NYSE") through Santander Investment Securities Inc., U.S.

**7. Inform, if applicable, the impacts that the trading shall have on the composition of the shareholding control or the administrative structure of the company.**

The operations under the buyback program will not affect the shareholding or management structures of the Company.

**8. Identify counterparties, if known, and, in case of related party of the company, as defined by accounting rules that govern such matter, provide the information required by Article 9 of CVM Resolution No. 81, of March 29<sup>th</sup>, 2022.**

The operations will be carried out on the B3, by Santander Corretora de Câmbio e Valores Mobiliários S.A., and ADRs shall be purchased on NYSE by Santander Investment Securities Inc., U.S., so it is not possible, at this moment, to identity the counterparties of the operations scope of the Buyback Program. Both B3 and NYSE act as central counterparty in transactions by their respective clearinghouses.

**9. Indicate the allocation of the proceeds of sale, if applicable.**

There is no specific provision for the allocation of proceeds in the event of sale of shares purchased through the buyback program.

**10. Inform the deadline for the settlement of the authorized operations.**

The settlement period at B3 and NYSE is two (2) days after the conclusion of each operation.

**11. Identify the institutions that shall act as intermediaries, if any.**

The Units shall be purchased on the B3, by market prices, through Santander Corretora de Câmbio e Valores Mobiliários S.A.

The ADRs shall be purchased on NYSE, by market prices, through Santander Investment Securities Inc., U.S.

**12. Specify the available funds to be used, according to Article 8, first paragraph, of CVM Resolution No. 77, of March 29<sup>th</sup>, 2022.**

According to the latest financial information of the Company regarding the accrued balance until December, 2024, the Company has available funds in the amount of R$32.7 billion in its capital reserve and revenues reserve accounts (excluding the legal reserve). The effective buyback shall depend of the existence of available funds at the acquisition moment, pursuant to Article 8 of CVM Resolution 77.

![](bsbr202509256k_001.jpg)

**13. Specify the reasons why members of the board of directors are comfortable that the repurchase of shares shall not affect the compliance of obligations assumed towards creditors or the payment of mandatory fixed or minimum dividends.**

The sum of the financial value of this buyback program is not material in relation to the Company's cash position, in order to affect its capacity to comply with obligations towards creditors or payment of minimum mandatory dividends.

São Paulo, September 25, 2025.
