Gilead Sciences Announces Third Quarter 2004 Financial Results

FOSTER CITY, Calif.--(BUSINESS WIRE)--Oct. 21, 2004--Gilead Sciences, Inc. (Nasdaq:GILD)

  • Total Quarterly Revenues of $326 Million, Up 63 Percent over Third Quarter 2003
  • Total Nine Month Revenues of $955 Million Surpasses Total Full Year Revenues for 2003
  • GAAP EPS of $0.25 Per Share

Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the third quarter ended September 30, 2004. Total revenues for the third quarter were $326.2 million, up 63 percent, compared to total revenues of $200.4 million for the third quarter of 2003. Operating cash flow for the quarter increased by 207 percent to $166.6 million, compared to $54.3 million for the same period last year.

Net income for the third quarter of 2004 was $113.2 million, or $0.25 per diluted share, an increase of 55 percent compared to net income of $73.1 million, or $0.17 per diluted share, for the third quarter of 2003. The third quarter of 2003 included a $13.2 million reimbursement that Gilead received after settling a contractual dispute with a vendor. This reimbursement was recorded as a reduction of research and development expenses and increased prior period earnings per share by nearly $0.03. Pre-tax income for the third quarter of 2004 increased substantially to $166.5 million, an increase of 116 percent, when compared to $77.0 million in the third quarter of 2003. The difference between the pre-tax and after-tax growth rates is principally due to the Company's effective tax rate, which increased to 32 percent during the third quarter of 2004 compared to 5 percent for the same period last year.

Net revenues from product sales totaled $310.7 million, up 60 percent from the third quarter of 2003. This growth was primarily driven by higher revenues from our HIV products, which includes Viread(R) (tenofovir disoproxil fumarate), Emtriva(R) (emtricitabine) and Truvada(TM) (emtricitabine and tenofovir disoproxil fumarate). HIV product sales were $228.1 million during the third quarter of 2004, up from $121.4 million in the third quarter of 2003, an increase of 88 percent. U.S. sales of the Company's HIV products in the third quarter of 2004 were $139.4 million, including Viread sales of $108.5 million, Truvada sales of $18.2 million, and Emtriva sales of $12.8 million. Growth in HIV product sales in the United States during the third quarter of 2004 was driven primarily by higher prescription volumes of Viread and Emtriva, as well as the launch of Truvada in August 2004. This growth was offset in part by additional reductions in U.S. distribution channel inventory levels of Viread as the three major wholesalers achieved the targets stipulated under our recently implemented inventory management agreements. HIV product sales outside the United States totaled $88.7 million, including Viread sales of $85.4 million and Emtriva sales of $3.2 million. Ex-U.S. HIV product sales growth for the third quarter of 2004 was driven by higher prescription volumes and a favorable currency environment. HIV product sales in the third quarter of 2004 were $5.9 million higher due primarily to a stronger European currency environment compared to the same quarter last year. AmBisome(R) (amphotericin B) liposome for injection sales for the third quarter of 2004 were $49.8 million, a decrease of 3 percent compared to the third quarter of 2003. This decrease was due to lower volumes resulting from increased competition in Europe, which offset a favorable currency impact of $2.8 million due to the stronger European currency when compared to the third quarter of 2003. Sales of Hepsera(R) (adefovir dipivoxil 10 mg) were $29.7 million for the third quarter of 2004, a substantial increase of 81 percent from $16.4 million in the third quarter of 2003. This was primarily driven by prescription growth in the United States and Europe, offset in part by reductions in U.S. distribution channel inventory levels as the three major wholesalers achieved the targets stipulated under our inventory management agreements.

"We are pleased with the third quarter results and the overall growth of our HIV franchise -- in particular, Truvada's rapid uptake and solid revenue performance after only nine weeks on the market," said John C. Martin, PhD, President and Chief Executive Officer of Gilead Sciences. "We continue to leverage our antiviral expertise and solid financial position to successfully grow our global HIV franchise."

For the third quarter of 2004, royalty and contract revenues resulting from collaborations with corporate partners totaled $15.5 million, compared to $6.3 million in the third quarter of 2003. Significant components of royalty and contract revenues for the third quarter of 2004 include royalties of $3.6 million on sales of AmBisome primarily in the United States by Gilead's co-promotion partner Fujisawa Healthcare, a $2.9 million milestone payment earned from EyeTech Pharmaceuticals upon the filing of a new drug application in Europe for Macugen(TM) (pegaptanib sodium injection) and $2.1 million received from Medarex, Inc. in conjunction with a royalty buyout agreement.

Research and development (R&D) expenses for the third quarter of 2004 were $49.2 million. R&D expenses for the third quarter of 2003 were $36.0 million, which included the favorable impact of a $13.2 million reimbursement resulting from the settlement of a contractual dispute with a vendor. Excluding the impact of this reimbursement, third quarter 2003 spending would have been $49.2 million. During prior periods, certain European phase IV clinical trial expenses that are now recorded as R&D expenses were recorded as selling, general and administrative expenses (SG&A). Such expenses for the third quarter of 2003 of $4.3 million have been reclassified from SG&A to R&D to be consistent with the current period presentation. Third quarter 2004 R&D expenses remained flat from the third quarter of 2003 primarily due to higher research spending associated with Gilead's proprietary prodrug technology and hepatitis C programs, offset by a lower level of clinical trials activity in the third quarter 2004.

SG&A expenses for the three months ended September 30, 2004 were $72.4 million, compared to $59.3 million for the same quarter of 2003 after the European phase IV clinical trial reclassification of $4.3 million to R&D expenses. The higher expenses are due primarily to increased global marketing efforts, the significant expansion of Gilead's U.S. and European sales forces toward the latter part of 2003, increased infrastructure costs, as well as the U.S. launch of Truvada.

The net foreign exchange impact on pre-tax earnings, including revenue and expenses generated from outside the United States, as well as hedging activity for the three and nine months ended September 30, 2004, was a favorable $7.9 million and $23.0 million, respectively, due primarily to a stronger Euro relative to the U.S. dollar.

Gilead also reported its results of operations for the nine months ended September 30, 2004. The Company recorded net revenues from product sales of $886.6 million and aggregate royalty and contract revenues of $68.4 million, up 53 percent and 189 percent, respectively, compared to the same period last year. Total revenues for the first nine months of 2003 included product sales of $580.7 million and aggregate royalty and contract revenues of $23.6 million. Sales of HIV products for the nine months ended September 30, 2004 were $646.7 million, up from $395.7 million in the nine months ended September 30, 2003. On a volume basis, for the nine months ended September 30, 2004, HIV product volume increased by 66 percent when compared to the first nine months of 2003; volume increased 58 percent in the U.S. and 82 percent in ex-U.S. countries. AmBisome sales for the nine months ended September 30, 2004 were $156.7 million compared to $143.8 million, a 9 percent increase over the nine months ended September 30, 2003. Due to the favorable currency environment, sales in the first nine months of 2004 were $21.2 million and $13.6 million higher for HIV and AmBisome products, respectively, when compared to the same period last year. Sales of Hepsera totaled $76.6 million for the first nine months of 2004, an increase of 121 percent over the $34.7 million in the first nine months of 2003.

Net income for the nine months ended September 30, 2004 was $339.1 million, or $0.74 per diluted share. This compares to a net loss of $264.6 million, or $0.66 per diluted share for the nine months ended September 30, 2003 which included a charge of $488.6 million for in-process research and development associated with the acquisition of Triangle Pharmaceuticals, Inc. in January 2003. Excluding this in-process research and development charge, non-GAAP earnings would have been $211.4 million or $0.49 per diluted share for the nine months ended September 30, 2003, which includes the impact of dilutive stock options and convertible debt.

Research and development expenses for the nine months ended September 30, 2004 and 2003 were $153.4 million and $122.9 million, respectively, which includes the reclassification of phase IV clinical trial expenses to R&D of $11.3 million for the first nine months of 2003. Excluding the $13.2 million vendor contract settlement mentioned above, R&D expenses for the nine months ended September 30, 2003 would have been $136.1 million. The higher expenses during the first nine months of 2004 are primarily attributable to increased headcount, costs associated with the development of Truvada and research spending related to the Company's proprietary prodrug technology.

Selling, general and administrative expenses for the nine months ended September 30, 2004 were $217.4 million, compared to $160.1 million for the first nine months ended September 30, 2003, which includes the reclassification of phase IV clinical trial expenses to R&D of $11.3 million for the nine months of 2003. The significant increase in expenses is primarily due to Gilead's increased global marketing efforts and the expansion of Gilead's U.S. and European sales forces to support the commercial launches of Viread, Hepsera, Emtriva and Truvada.

As of September 30, 2004, the Company had cash, cash equivalents and marketable securities of $1.15 billion, compared to $707.0 million at December 31, 2003. The increase in cash, cash equivalents and marketable securities is primarily attributable to strong operating cash flow of $387.3 million for the nine months ended September 30, 2004.

In late July 2004, Gilead announced that its Board of Directors approved a two-for-one split of the Company's outstanding common stock, payable to shareholders of record as of August 12, 2004. The Company's stock began trading at the post-split price on September 7, 2004. All share and per share data in this press release reflect this two-for-one stock split.

Corporate Highlights

In July 2004, Gilead announced that it had entered into inventory management agreements (IMAs) with AmerisourceBergen Drug Corporation, Cardinal Health, Inc. and McKesson Corporation, three major pharmaceutical wholesalers that distribute about 90 percent of the portfolio of products Gilead sells in the United States.

In September, Gilead announced that Kevin Young joined the Company as Executive Vice President, Commercial Operations, a newly-created position following the Company's expansion and reorganization of its commercial operations earlier this year.

In early October, Gilead announced that the Company was calling for redemption on November 20, 2004 all of its outstanding 2% Convertible Senior Notes due December 15, 2007 (the Notes). The aggregate principal amount outstanding of the Notes is $345.0 million as of September 30, 2004.

Product and Pipeline Highlights

"This quarter saw our HIV franchise continue its strong growth with the approval of Truvada, our third once-a-day HIV therapeutic and fourth once-a-day antiviral approved by the FDA in less than three years," said Dr. Martin. "With this once-daily fixed-dose product, doctors and patients now have a new weapon in their fight against HIV that may make it easier to construct convenient combination regimens. Additionally, we were pleased to announce our collaboration with Genelabs Technologies to develop novel compounds for the treatment of hepatitis C, a serious life-threatening disease that represents an important unmet medical need."

HIV/AIDS Franchise

In July, Gilead announced a 37 percent reduction in the price of Viread for use in the developing world. Gilead provides Viread through the Global Access Program at a no-profit price in every country in Africa and in 15 additional countries in other parts of the world classified as "least developed" by the United Nations. This reduction resulted from improvements in the manufacturing process for Viread and increased economies of scale.

Also in July, the Company announced the publication of results from two separate studies evaluating the efficacy and safety of Viread and Emtriva, respectively, compared with stavudine (d4T), in combination with other antiretroviral agents. These data appeared in the July 14, 2004 edition of the Journal of the American Medical Association, a special issue that was published to coincide with the 15th International AIDS Conference, which took place in Bangkok, Thailand.

In early August, Gilead announced that the U.S. Food and Drug Administration granted expedited approval for Truvada, a fixed-dose combination of the Company's anti-HIV medications Emtriva and Viread. Gilead began shipping Truvada to wholesalers within days of approval.

In mid-August, the Company announced that it will provide access to Truvada through Gilead's Global Access Program and Advancing Access Program. The Advancing Access Program helps ensure access to the Company's products for patients in the United States who cannot obtain reimbursement or afford to pay for the product.

In late August, Gilead announced positive preliminary data from a planned interim 24-week analysis of the Company's ongoing Study 934. This study, a 48-week clinical trial, was designed to compare a regimen of Viread, Emtriva and efavirenz to Combivir(R) (lamivudine 150 mg/zidovudine 300 mg) and efavirenz in more than 500 treatment-naive patients with HIV.

In September, the Company announced the acceptance of a late breaker presentation of the 24-week interim data from Study 934 at the 44th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Washington, DC. The data will be presented on Sunday, October 31, 2004 at 4:20 p.m. Eastern.

Today, Gilead announced the discontinuation of early stage development programs for GS 7340 and GS 9005 for the potential treatment of HIV.

Hepatitis Franchise

At the end of the quarter, Gilead and Genelabs Technologies, Inc. (Nasdaq: GNLB) announced that the companies have signed an agreement to collaborate in the research, development and commercialization of novel nucleoside polymerase inhibitors for the treatment of infection caused by the hepatitis C virus.

Notes:

(1) The adjustment reflects a pre-tax gain of $20.6 million related to
our warrants in EyeTech Pharmaceuticals, Inc., which completed its
initial public offering during the first quarter.

(2) The non-GAAP results for the nine months ended September 30, 2003
exclude the first quarter in-process research and development charge
of $488.6 million from the acquisition of Triangle Pharmaceuticals,
Inc., as well as the third quarter reimbursement to Gilead of $13.2
million of research and development expenses resulting from the
settlement of a contractual dispute with a vendor.

(3) Certain prior period amounts associated with phase IV clinical
trial expenses totaling $4.9 million and $11.3 million for the nine
months ended September 30, 2004 and 2003, respectively, have been
reclassified from selling, general and administrative to research and
development to be consistent with the current period presentation.

(4) Net income per share and the number of shares used in the per
share calculation for all periods presented reflect the two-for-one
stock split effective August 12, 2004.

(5) In accordance with Statement of Financial Accounting Standard No.
128, using the If-Converted Method, interest expense related to
convertible debt of $3.9 million has been added back to net income for
purposes of calculating diluted net income per share for the nine
months ended September 30, 2004, and $13.8 million for the nine months
ended September 30, 2003. The shares used in the calculation of net
income per diluted share for the nine months ended September 30, 2004
includes the effect of 19.1 million stock options outstanding and the
effect of the $345.0 million 2% convertible senior debt, which
converts to approximately 14.7 million shares. The shares used in the
calculation of net income per diluted share for the nine months ended
September 30, 2003 includes the effect of 25.5 million stock options
outstanding and the effect of the $345.0 million 2% convertible senior
debt and $250.0 million 5% convertible subordinated debt, which
convert to approximately 14.7 million and 20.4 million shares,
respectively.
