Gilead to Offer $1.1 Billion Convertible Senior Notes; Company to Repurchase Approximately $500 Million in Common Stock

FOSTER CITY, Calif.--(BUSINESS WIRE)--April 18, 2006--Gilead Sciences, Inc. (Nasdaq:GILD) today announced its intention to offer, subject to market and other conditions, approximately $550 million principal amount of Convertible Senior Notes due 2011 and approximately $550 million principal amount of Convertible Senior Notes due 2013 through offerings to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). The notes will be convertible under certain circumstances. Upon conversion, holders will receive cash up to the principal amount, and any excess conversion value will be delivered, at our election, in cash, common stock or a combination of cash and common stock. Gilead also expects to grant the initial purchasers an option to purchase additional notes to cover overallotments.

Gilead expects to use the net proceeds from the offering and the proceeds of the warrant transactions referred to below to repurchase approximately $500 million worth of shares of its common stock contemporaneously with the closing of the sale of the notes. In addition, proceeds from the transactions will be used to fund convertible note hedge transactions that Gilead expects to enter into with one or more of the initial purchasers of the notes and/or their affiliates. Any remaining proceeds from the transactions will be added to Gilead's working capital and will be used for general corporate purposes.

The convertible note hedge transactions are intended to offset the dilution to Gilead common stock upon potential future conversion of the notes. Gilead also expects to enter into separate warrant transactions with one or more of the initial purchasers and/or their affiliates.

This notice does not constitute an offer to sell or the solicitation of an offer to buy securities. Any offers of the securities will be made only by means of a private offering memorandum. The securities and the shares of Gilead common stock issuable upon conversion or exercise of the securities have not been, and will not be, registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
