Telefônica Brasil S.A. (“Company”) informs its Shareholders that the Company’s Executive Board has decided to set the payment date for the interest on capital (“IoC”) declared in the 2^nd, 3^rd and 4^th quarters of 2025 at meetings of the Board of Directors held on April 1, 2025; May 12, 2025; June 12, 2025; July 14, 2025; August 14, 2025; September 11, 2025; October 14, 2025; November 13, 2025; and December 16, 2025, as well as the resources resulting from the Capital Stock Reduction to be declared at the Extraordinary Shareholders’ Meeting (“ESM”), to be held on March 12, 2026 (“Capital Reduction”), as detailed below:

IoC:

¹ The amount per share declared on April 1, 2025, was recalculated and is being presented considering the effects of the Company’s reverse stock split and forward stock split operation carried out on April 15, 2025.

As provided for in Article 26 of the Company’s Bylaws, the net amount of said IoC will be imputed to the mandatory minimum dividend for the fiscal year ended December 31, 2025, ad referendum of the Ordinary Shareholders’ Meeting to be held on April 16, 2026.

The IoC not claimed within a period of 03 (three) years from the payment date will prescribe and revert to the Company, pursuant to Law No. 6,404, of December 15, 1976, Article 287, Item II, item “a”.

Capital Reduction:

TELEFÔNICA BRASIL S.A.

Publicly Held Company

CNPJ No. 02.558.157/0001-62 - NIRE 35.3.001.5881-4

The Company informs that the Capital Reduction is subjected to the approval by shareholders at ESM, to be held on March 12, 2026, and, if approved, it will become effective after the 60-day period, beginning on the publication of the ESM minutes, as provided for in Article 174 of Law No. 6,404/1976.

Due to the Company’s Share Buyback Program, the amount per share specified in the Capital Reduction table above may change considering the Company’s shareholding base to be verified on May 22, 2026. Thus, the shareholding position considered for receiving the resources resulting from the Capital Reduction will be based on the Company’s records at the end of May 22, 2026, and, after this date, the shares issued by the Company will be traded ex-reimbursement rights.

If the Capital Reduction is approved at the ESM, the resources will be paid in a single instalment, individually to each shareholder, based on the respective shareholding position in the Company’s capital.

The Company will, in due course, disclose the documents and procedures required from non-resident shareholders for tax purposes, including any potential withholding income tax on capital gains resulting from the Capital Reduction. Regarding investors resident in Brazil, the appropriate tax treatment must be identified directly by the respective shareholders and advisors.

The payment of the IoC and the resources resulting from the Capital Reduction to shareholders who have a banking option in the shareholder register with Banco Bradesco S.A. will be made directly into the indicated accounts. For shareholders with shares in Fiduciary Custody of the Stock Exchanges, payment will be made through Brokerage Firms. The other shareholders must go to any branch of Banco Bradesco S.A., carrying their identification documents.

São Paulo, February 23, 2026.
