CNPJ No. 02.558.157/0001-62 - NIRE 35.3.0015881-4

**MATERIAL FACT**

**Telefônica Brasil S.A.** ("<u>Company</u>") (B3: VIVT3; NYSE: VIV), in accordance with Article 157, paragraph 4, of Law No. 6,404, of December 15, 1976 ("<u>Brazilian Corporate Law</u>"), and CVM Resolution No. 44, of August 23, 2021, hereby informs its shareholders and the market in general that, at a meeting held on this date, the Board of Directors approved the cancellation of 34,740,770 common, book-entry and non-par value shares issued by the Company and held in treasury, representing 1.07% of the capital stock, without reducing its value. These shares were acquired under the Company's Share Buyback Program.

As a result of the approved cancellation of shares, the Company's capital stock is now divided into 3,226,546,622 common, book-entry and non-par value shares. Additionally, a Shareholders' General Meeting will be convened in due course to amend the caput of Article 5 of the Company's Bylaws to reflect the new number of shares comprising the capital stock.

Finally, the Company clarifies that, due to the reverse stock split with subsequent forward stock split of its own shares, which was effective on April 15, 2025, the maximum number of shares that may be acquired under the current share buyback program, approved on February 25, 2025, has been automatically adjusted.

São Paulo, July 24, 2025.
