TELEFÔNICA BRASIL ANNOUNCES LAUNCH OF EQUITY OFFERING

São Paulo, March 26, 2015 — Telefônica Brasil S.A. (NYSE: VIV; BOVESPA: VIVT3.ON and VIVT4.PN) (“Telefônica Brasil”) announced today the launch of an offering of 219,950,615 preferred shares (or up to 7,746,660 preferred shares if the international and Brazilian underwriters’ options to purchase additional shares are exercised in full) as part of a global offering, which consists of an international offering in the United States and other countries outside Brazil and a concurrent offering of common shares and preferred shares in Brazil. Preferred shares offered in the global offering may be offered directly or in the form of American Depositary Shares (“ADSs”), each of which represents one preferred share of Telefônica Brasil.

Holders of Telefônica Brasil’s preferred shares as of April 1, 2015 will be given the opportunity to subscribe for preferred shares in the Brazilian offering on a priority basis at the public offering price. The priority subscription procedure will not be made available to holders of ADSs or to shareholders located in jurisdictions in which such offering would be unlawful. The number of preferred shares available for sale in the global offering to investors will be reduced to the extent that existing shareholders of Telefônica Brasil subscribe on the priority basis for preferred shares in the Brazilian offering.

Telefônica Brasil intends to use the net proceeds from the global offering to (1) fund the cash portion of the GVT acquisition, which is expected to close by mid-2015, (2) repay GVT’s loans with a related party, and (3) adjust its capital structure in order to maintain liquidity.

Itau BBA, Morgan Stanley, BofA Merrill Lynch and Santander are acting as global coordinators and Bradesco BBI, BTG Pactual, Credit Suisse, Goldman, Sachs & Co., HSBC and J.P. Morgan are acting as joint bookrunners in connection with the international offering.

The international offering is being made pursuant to an effective registration statement (including a base prospectus) on Form F-3 filed with the U.S. Securities and Exchange Commission (“SEC”) on March 26, 2015. A copy of the preliminary prospectus supplement and accompanying base prospectus relating to the international offering may be obtained by contacting Itaú BBA, 767 Fifth Avenue, 50th Floor, New York, NY 10153, attention: Investment Banking Department — Equity Capital Markets; Morgan Stanley & Co.
