NOTICE TO THE MARKET

LAUNCH OF VIVO PAY

Telefônica Brasil S.A. (“Vivo”) (B3: VIVT3 / NYSE: VIV) hereby announces to its shareholders and the market in general about the launch of Vivo Pay, a fully digital account that allows for banking transactions directly through the application.

This initiative reinforces Vivo's presence in the financial services space and the company's ongoing evolution as a hub of digital services that go beyond connectivity.
