Gilead Sciences Announces Fourth Quarter and Full Year 2002 Financial Results; Full Year Product Sales of $424 Million, Up 122 Percent over 2001; Net Income of $72 Million for 2002

FOSTER CITY, Calif.--(BUSINESS WIRE)--Jan. 30, 2003--Gilead Sciences, Inc. (Nasdaq:GILD) announced today its results of operations for the fourth quarter ended December 31, 2002. Total revenues for the fourth quarter were $145.0 million, up 95 percent, compared to total revenues of $74.3 million for the fourth quarter of 2001. Net income for the fourth quarter 2002 was $35.5 million, or $0.17 per diluted share. This compares to net income in the fourth quarter 2001 of $131.6 million, or $0.62 per share, which included a one-time non-operating gain of $157.8 million from the sale of oncology assets and related technology to OSI Pharmaceuticals (OSI).

Gilead achieved positive operating cash flow for both the fourth quarter and the full year 2002. Operating cash flow for the quarter was $35.5 million, driven by higher earnings and improved collections compared with cash used in operations of $34.2 million for the same period last year. Operating cash flow for the year was $74.4 million, compared with cash used in operations of $127.0 million for the full year 2001.

Net revenues from product sales totaled $139.2 million, up 133 percent from the fourth quarter 2001. This growth was primarily driven by higher revenues from Viread(R) (tenofovir disoproxil fumarate) and AmBisome(R) (amphotericin B) liposome for injection. Sales of Viread were $85.0 million in the fourth quarter of 2002, up from $13.2 million in the fourth quarter of 2001 and $68.9 million in the third quarter of 2002. AmBisome sales for the fourth quarter of 2002 were $49.6 million, an increase of 16 percent compared to the fourth quarter of 2001. Excluding the impact of foreign currencies relative to the U.S. dollar, AmBisome sales grew 7 percent for the fourth quarter of 2002 over the comparable quarter of 2001.

"Delivering on its promise, Gilead achieved profitability on an operating basis for the fourth quarter and full year 2002, driven by the solid financial performance of Viread and AmBisome," said John C. Martin, PhD, president and chief executive officer of Gilead Sciences. "This is a testament to the need for novel anti-infectives with unique profiles, and Gilead's commitment to deliver returns to its investors."

For the fourth quarter of 2002, royalty and contract revenues resulting from collaborations with corporate partners totaled $5.8 million. These revenues primarily relate to royalties on sales of AmBisome in the United States by Gilead's co-promotion partner Fujisawa Healthcare.

Research and development expenses for the fourth quarter of 2002 were $35.0 million, compared to $44.6 million for the same quarter in 2001. The lower expenses during the fourth quarter of 2002 is primarily attributable to lower clinical spending for Viread and the divestiture of Gilead's oncology portfolio to OSI in December 2001.

Selling, general and administrative expenses for the three months ended December 31, 2002 were $57.6 million, compared to $41.5 million for the same quarter of 2001. The significant increase in expenses is primarily due to increased global marketing efforts and the expansion of Gilead's U.S. and European sales forces to support the commercial launches of Viread and Hepsera(TM) (adefovir dipivoxil).

Gilead also reported its results of operations for the year ended December 31, 2002. The company recorded net revenues from product sales of $423.9 million and aggregate contract and royalty revenues of $42.9 million. Sales of Viread for the year ended December 31, 2002 were $225.8 million, or 53 percent of product sales. AmBisome sales for the year ended December 31, 2002 were $185.7 million, a 13 percent increase over the year ended December 31, 2001. Excluding the impact of foreign currencies relative to the U.S. dollar, AmBisome sales grew 9 percent for the year ended December 31, 2002 over the comparable period of 2001. Net revenues of $466.8 million for the year ended December 31, 2002 compare to net revenues of $233.8 million in 2001. Net revenues for 2001 included product sales of $191.0 million and aggregate contract and royalty revenues of $42.8 million.

Net income for the year ended December 31, 2002 was $72.1 million, or $0.35 per diluted share, which includes a one-time non-operating loss of $16.0 million realized upon the July 2002 sale of Gilead's shares in OSI. This compares to net income of $52.3 million, or $0.26 per diluted share, for the year ended December 31, 2001, which includes the gain of $157.8 million from the sale of oncology assets and related technology to OSI.

Research and development expenses for the year ended December 31, 2002 and 2001 were $134.8 million and $185.6 million, respectively. The substantially lower expenses during 2002 were attributable to lower Viread clinical trial costs, the divestiture of Gilead's oncology portfolio to OSI in December 2001, and upfront licensing payments in 2001.

Selling, general and administrative expenses for the year ended December 31, 2002 were $181.3 million compared to $125.1 million for the same period in 2001. The significant increase in expenses is primarily due to increased global marketing efforts and the expansion of Gilead's U.S. and European sales forces to support the commercial launches of Viread and Hepsera.

Corporate Highlights

On December 4, 2002, Gilead announced an agreement to acquire Triangle Pharmaceuticals, Inc. The transaction, structured as a two-step acquisition, was comprised of a cash tender offer for all of the outstanding Triangle common stock at $6.00 per share, followed by a cash merger in which Gilead acquired all remaining outstanding Triangle common stock at $6.00 per share. The transaction was completed on January 23, 2003.

In December 2002, the company sold $345 million of convertible notes, including the fully exercised over-allotment of $45 million, to qualified institutional buyers through a Rule 144A offering. Gilead expects to use the proceeds from the offering for general corporate purposes, including the acquisition of Triangle Pharmaceuticals, Inc., potential future product or company acquisitions, capital expenditures and working capital.

Products and Pipeline Highlights

"The fourth quarter marked a period of significant progress for Gilead, underscored by the continued uptake of Viread and the introduction of Hepsera to the U.S. market," said Dr. Martin. "Importantly, our acquisition of Triangle Pharmaceuticals significantly expanded our pipeline and increased our opportunity for continued growth. We believe that we are uniquely positioned to take full advantage of the value that the Triangle product portfolio has to offer, especially through the potential co-formulation of Viread and emtricitabine (FTC)."

Viread for HIV/AIDS

During the fourth quarter of 2002, Gilead established pricing for Viread and launched the drug in additional territories, including Austria and Australia. In January, Gilead launched Viread in Italy.

In late October 2002, the Bill & Melinda Gates Foundation announced that it awarded Family Health International (FHI) a $6.5 million grant to conduct a multinational clinical trial evaluating Viread as a method of HIV prevention in resource-poor countries with high HIV incidence. Gilead will be supplying Viread for the study, which is designed to evaluate the safety and efficacy of the drug as a method of reducing the risk of HIV infection in sexually active women who are regularly exposed to the virus.

In December 2002, Gilead announced that it would provide every country in Africa and 15 additional countries in other parts of the world classified as "least developed" by the United Nations access to Viread at no profit pricing. The program, which is expected to be operational by mid-2003, will provide Viread at a reduced price that represents only the cost of manufacturing and distributing the drug and administering the program. Gilead also will participate in the "Development of Antiretroviral Therapies" (DART) study, a clinical trial sponsored by United Kingdom's Medical Research Council designed to evaluate antiretroviral management strategies in resource-limited parts of the world.

Hepsera for Chronic Hepatitis B

In early November 2002, Gilead took part in the 53rd Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in Boston, Massachusetts. During the meeting the company presented 48-week results from a clinical trial (Study 461) evaluating the antiviral activity and safety of Hepsera in patients with lamivudine-resistant virus.

Also in November 2002, the company announced that the European Union's Committee for Proprietary Medicinal Products (CPMP), the scientific committee of the European Medicines Evaluation Agency (EMEA), recommended granting Marketing Authorisation for Hepsera for the treatment of chronic hepatitis B in all 15 member states of the European Union. On the basis of the CPMP's recommendation, the European Commission will consider granting final Marketing Authorisation, which is anticipated to occur by mid-2003.

Emtricitabine (FTC) for HIV/AIDS

Emtricitabine, Triangle's lead product prior to the company's acquisition by Gilead, was accepted for review in January 2003 by the European Union's EMEA. Emtricitabine is a one pill, once daily nucleoside analogue for the treatment of HIV infection and also is currently under review by the U.S. Food and Drug Administration (FDA), with a PDUFA (Prescription Drug User Fee Act) action date of July 3, 2003.
