Record Product Sales of $670.1 Million, Up 43 Percent Over Third Quarter 2005 Net Loss Per Share of $(0.11); Non-GAAP EPS of $0.64 Per Share, Excluding Purchased In-Process Research and Development Charge Business Editors/Health/Medical Writers

FOSTER CITY, Calif.--(BUSINESS WIRE)--Oct. 18, 2006--Gilead Sciences, Inc. (Nasdaq:GILD) announced today its results of operations for the quarter ended September 30, 2006. Total revenues for the third quarter of 2006 were $748.7 million, up 52 percent compared to total revenues of $493.5 million for the third quarter of 2005. Net loss for the third quarter of 2006 was $52.2 million, or $(0.11) per diluted share, which included a charge of $355.6 million for purchased in-process research and development (IPR&D) incurred in connection with the acquisition of Corus Pharma, Inc. (Corus) in August 2006 and after-tax stock-based compensation expense of $25.6 million reflecting the impact of the adoption of the Financial Accounting Standards Board's Statement No. 123 (revised 2004), "Share Based Payment" (SFAS 123R) on January 1, 2006. Excluding the impact of the IPR&D charge, non-GAAP net income for the third quarter of 2006 was $303.4 million, or $0.64 per diluted share. Net income for the third quarter of 2005 was $179.2 million, or $0.38 per diluted share.

Product Sales

Product sales were a record $670.1 million for the third quarter of 2006, up 43 percent over the same period in 2005, marking twelve consecutive quarters of product sales growth. This growth continues to be driven primarily by Gilead's HIV product franchise, including the strong performance of Truvada(R) (emtricitabine and tenofovir disoproxil fumarate) and the rapid uptake of Atripla(TM) (efavirenz 600 mg/ emtricitabine 200 mg/ tenofovir disoproxil fumarate 300 mg) following its U.S. launch in July of this year, as well as continued solid product sales of Hepsera(R) (adefovir dipivoxil).

HIV Franchise

HIV product sales were $557.3 million in the third quarter of 2006, a 53 percent increase from $363.5 million for the same period in 2005.

-- Truvada

Truvada sales were $309.0 million for the third quarter of 2006, an increase of 90 percent from Truvada sales in the third quarter of 2005. Truvada sales accounted for more than 55 percent of Gilead's total HIV product sales in the third quarter of 2006.

-- Viread

Sales of Viread(R) (tenofovir disoproxil fumarate) were $170.6 million in the third quarter of 2006, a 10 percent decrease from $189.4 million in the third quarter of 2005. Viread sales volume has decreased due primarily to patients switching from a Viread-containing regimen to one containing Truvada in countries where Truvada is available.

-- Atripla
Sales of Atripla were $68.4 million in the third quarter of 2006.

-- Emtriva
Emtriva(R) (emtricitabine) sales were $9.3 million for the third quarter of 2006, down 21 percent from the third quarter of 2005. Emtriva sales volume has decreased due primarily to patients switching from an Emtriva-containing regimen to one containing Truvada in countries where Truvada is available.

AmBisome for Severe Fungal Infections

Sales of AmBisome(R) (amphotericin B) liposome for injection for the third quarter of 2006 were $55.3 million, an increase of one percent compared to the third quarter of 2005.

Hepsera for Chronic Hepatitis B

Sales of Hepsera totaled $55.1 million for the third quarter of 2006, an 18 percent increase from $46.9 million in the third quarter of 2005. The increase in sales for the third quarter of 2006 was primarily driven by strong volume growth in Europe.

Royalty and Contract Revenues

For the third quarter of 2006, royalty and contract revenues resulting from collaborations with corporate partners totaled $78.7 million, an increase of $52.4 million from the third quarter of 2005. The increase in the third quarter of 2006 was primarily driven by the recognition of Tamiflu(R) (oseltamivir phosphate) royalties from F. Hoffmann-La Roche Ltd (Roche) of $62.7 million. This amount was significantly higher than the Tamiflu royalties of $12.1 million recognized in the third quarter of 2005. The increase was primarily due to the significantly higher Tamiflu sales recorded by Roche during the second quarter of 2006 compared to the same period in 2005, as well as the elimination of a contractual cost of goods adjustment that had historically reduced the amount of Tamiflu royalties recognized by Gilead.

"We are pleased to have achieved a very solid third quarter in 2006, including total revenues of $749 million," said John F. Milligan, Ph.D., Executive Vice President and Chief Financial Officer of Gilead. "Revenues from the first nine months of this year have already exceeded total revenues recorded for all of last year. Our continued sales growth is a result of strong initial uptake of Atripla, robust U.S. and international sales of Truvada, and continued solid performance of both Hepsera and AmBisome in increasingly competitive markets."

Research and Development

Research and development (R&D) expenses for the third quarter of 2006 were $93.3 million, which included stock-based compensation expense of $13.3 million, compared to R&D expenses of $78.8 million for the same quarter in 2005. R&D expenses for the third quarter of 2006 were higher due to increased headcount and increased clinical, product development and research activities associated with our HIV, hepatitis B and hepatitis C programs, as well as stock-based compensation expense from Gilead's adoption of SFAS 123R. During the third quarter of 2005, Gilead made a $15.0 million payment to Emory University (Emory) in connection with the amendment of our existing license agreement with Emory related to our obligation to develop emtricitabine for the hepatitis B indication.

Selling, General and Administrative

Selling, general and administrative (SG&A) expenses for the third quarter of 2006 were $132.5 million, which included stock-based compensation expense of $16.0 million, compared to SG&A expenses of $100.9 million for the same quarter in 2005. The higher SG&A expenses in the third quarter of 2006 as compared to the third quarter of 2005 were primarily due to increased headcount and expenses driven by our significant business growth and business development activities, as well as stock-based compensation expense from Gilead's adoption of SFAS 123R.

Purchased In-Process Research and Development

In August 2006, Gilead completed its acquisition of Seattle-based Corus and recorded a charge of $355.6 million to reflect Corus's incomplete IPR&D programs. Gilead did not record any income tax benefit for this charge.

Cash, Cash Equivalents and Marketable Securities

As of September 30, 2006, Gilead had cash, cash equivalents and marketable securities of $3.20 billion. This compared to $2.31 billion as of December 31, 2005. The increase in cash, cash equivalents and marketable securities was primarily attributable to $738.6 million of operating cash flows generated during the first nine months of 2006 and $587.6 million of net proceeds generated from our issuance of convertible senior notes and related transactions, offset by $356.2 million in net cash paid on our acquisition of Corus and $161.0 million paid toward principal on our term loan.

Other Balance Sheet Highlights

Inventories increased by $156.4 million from December 31, 2005 to $373.3 million as of September 30, 2006, primarily driven by increases in Atripla inventory, which includes the purchases of Sustiva(R) (efavirenz) active pharmaceutical ingredient from Bristol-Myers Squibb (BMS) at BMS' approximate market value of Sustiva.

Corporate Highlights

In July 2006, Gilead announced a donation to The Institute of Organic Chemistry and Biochemistry at the Academy of Sciences of the Czech Republic (IOCB) for the establishment of a Gilead Sciences Research Centre. Gilead will provide a $1.1 million annual donation to IOCB for an initial five-year term to fund the Centre's operations and ongoing research activities.

In August 2006, Gilead and Merck & Co., Inc. (Merck) announced that the companies established an agreement for the distribution of Atripla in developing countries around the world.

In August 2006, Gilead announced that it completed its acquisition of Corus following an initial investment of $25.0 million in Corus in April 2006. Corus's lead product candidate, aztreonam lysine for inhalation, is an inhaled antibiotic with activity against Gram-negative bacteria including Pseudomonas aeruginosa, which can cause lung infections in patients with cystic fibrosis. The product candidate is currently being evaluated in Phase III clinical studies.

Also in August and September of 2006, Gilead announced that it signed non-exclusive agreements to provide eleven generic companies in India with a license to produce and distribute generic versions of Viread to 95 low-income countries around the world, including India.

In September 2006, Gilead and BMS announced an agreement to commercialize Atripla in Canada for the treatment of HIV-1 infection in adults, subject to the approval of the product by Health Canada.

In October 2006, Gilead and Myogen, Inc. (Myogen), announced that the companies have signed a definitive agreement under which Gilead plans to acquire Myogen for approximately $2.5 billion. Myogen is a publicly held biopharmaceutical company focused on the discovery, development and commercialization of small molecule therapeutics for the treatment of cardiovascular disorders. This press release is neither an offer to purchase nor a solicitation of an offer to sell any securities of Myogen. A tender offer for Myogen's outstanding shares is being made only by the Offer to Purchase filed with the Securities and Exchange Commission on October 16, 2006.

Product and Pipeline Highlights

"We are all very proud of Gilead's achievements in the third quarter of 2006," said John C. Martin, PhD, President and Chief Executive Officer of Gilead. "After only a two and a half month review period, we, along with our partner Bristol-Myers Squibb, received U.S. approval for Atripla, the first-ever once-daily single tablet regimen for the treatment of HIV-1 infection in adults. I am pleased to report that Atripla is off to a very strong launch and am proud that we have contributed to providing improved dosing convenience for many physicians and patients. We also worked diligently in partnership with colleagues at Bristol-Myers Squibb and Merck to complete the submission of our Marketing Authorisation Application for Atripla in the European Union earlier this month."

Dr. Martin continued, "We also made significant progress with our research programs during the third quarter. This progress will be further augmented, pending the completion of our acquisition of Myogen, by the addition of ambrisentan to Gilead's pipeline - a product with important potential for the treatment of pulmonary arterial hypertension. The Myogen transaction allows Gilead to strengthen our efforts in the specialty market of pulmonary-related diseases, as initially established with our acquisition of Corus."

HIV Franchise

In July 2006, Gilead and BMS announced that the U.S. Food and Drug Administration granted approval of Atripla for the treatment of HIV-1 infection in adults.

In August 2006, Gilead announced the presentation of positive 96-week data from an ongoing clinical trial (Study 934) comparing a once-daily regimen of Viread, Emtriva and Sustiva to a twice-daily regimen of Combivir(R) (lamivudine/zidovudine) with Sustiva once daily in treatment-naive adults with HIV. The data were presented at the XVI International AIDS Conference, which took place August 13 to 18, 2006 in Toronto, Canada.

In September 2006, Gilead announced two presentations of long-term efficacy and safety data from Study 903E, evaluating the company's once-daily anti-HIV medication, Viread, as part of combination therapy. Data from both analyses of Study 903E were presented at the 8th International Workshop on Adverse Drug Reactions and Lipodystrophy in HIV, held September 24 to 26, 2006 in San Francisco, California.

Non-GAAP Financial Information

Non-GAAP earnings and earnings per diluted share are presented excluding the impact of the IPR&D charge incurred in connection with the acquisition of Corus. Our management believes this non-GAAP information is useful for investors, in conjunction with our GAAP financial statements, because it facilitates the comparison of current and prior period operating results after eliminating the effect of expense components that are individually material in the current period but were not present in the prior period. Non-GAAP financial information no longer excludes stock-based compensation expense resulting from our adoption of SFAS 123R on January 1, 2006 as management believes that investors have gained a better understanding of stock-based compensation expense and are now including such expense in their evaluation of the company; however, note 1 to the condensed consolidated statements of operations on page 6 of the attached press release continues to enable management and investors to understand the comparative impact of stock-based compensation expense on the various captions of the statements of operations in 2006. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of our operating results as reported under GAAP.

 net income per diluted share for the nine months ended September 30,
 2006 include the effect of outstanding stock options to purchase 19.3
 million shares of common stock applying the treasury stock method.

(3) For the nine months ended September 30, 2006, cost of goods sold
 includes $6.8 million recorded in the first quarter of 2006 to
 decrease the book value of inventory for our Access Program to
 reflect its net realizable value.

(4) For the three and nine months ended September 30, 2006, we
 incurred $355.6 million of purchased in-process research and
 development as a result of our acquisition of Corus Pharma, Inc.

       RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL INFORMATION
                             (unaudited)
               (in thousands, except per share amounts)

Below is a reconciliation of our GAAP operating results and per share
 amounts as reported in the attached press release.  Non-GAAP earnings
 and earnings per diluted share are presented excluding the impact of
 the purchased in-process research and development charge incurred in
 connection with the acquisition of Corus. Our management believes
 this non-GAAP information is useful for investors, in conjunction
 with our GAAP financial statements, because it facilitates the
 comparison of current and prior period operating results after
 eliminating the effect of expense components that are individually
 material in the current period but were not present in the prior
 period. Non-GAAP financial information no longer excludes stock-based
 compensation expense resulting from our adoption of SFAS 123R on
 January 1, 2006 as management believes that investors have gained a
 better understanding of stock-based compensation expense and are now
 including such expense in their evaluation of the company; however,
 note 1 to the condensed consolidated statements of operations on page
 6 of the attached press release continues to enable management and
 investors to understand the comparative impact of stock-based
 compensation expense on the various captions of the statements of
 operations in 2006. Non-GAAP information is not prepared under a
 comprehensive set of accounting rules and should only be used to
 supplement an understanding of our operating results as reported
 under GAAP.
