Gilead Sciences Announces Fourth Quarter and Full Year 2004 Financial Results

FOSTER CITY, Calif.--(BUSINESS WIRE)--Jan. 27, 2005--Gilead Sciences, Inc. (Nasdaq:GILD)

  • Full Year Record Product Sales of $1.24 Billion, Up 49 Percent over 2003
  • Full Year HIV Product Sales of $908 Million, Up 58 Percent over 2003
  • Fourth Quarter GAAP EPS of $0.24; Full Year GAAP EPS of $0.99

Gilead Sciences, Inc. (Nasdaq:GILD) announced today its results of operations for the fourth quarter ended December 31, 2004. Total revenues for the fourth quarter of 2004 were $369.6 million, up 40 percent, compared to total revenues of $263.5 million for the fourth quarter of 2003. Net income for the fourth quarter 2004 was $110.2 million, or $0.24 per diluted share, compared to net income of $192.6 million, or $0.43 per diluted share, for the fourth quarter of 2003. Non-GAAP net income for the fourth quarter increased 26 percent from $91.4 million, or $0.21 per diluted share, in 2003, to $114.8 million, or $0.25 per diluted share in 2004, an increase of $23.4 million.

During the fourth quarter of 2004, Gilead recorded a non-operating charge of $7.4 million related to a make-whole payment made as a result of the redemption of our $345.0 million 2% convertible senior debt. During the fourth quarter of 2003, Gilead recorded non-cash impairment charges related to certain long-lived assets of $10.9 million related to other asset write-downs charged to cost of goods sold, which were primarily driven by the decision to terminate liposomal research and development activities and to discontinue the DaunoXome product line, and a one-time income tax benefit of $111.6 million related to the reduction of the valuation allowance against our net deferred tax assets.

Operating cash flow for the fourth quarter of 2004 was $124.1 million, compared to operating cash flow of $99.9 million for the fourth quarter of 2003, an increase of approximately 24 percent. This marked Gilead's eighth consecutive quarter of positive cash flow from operations. Operating cash flow for the full year 2004 was $511.4 million, compared to operating cash flow of $234.6 million for the full year 2003.

Fourth Quarter 2004 Financial Results

Net revenues from product sales totaled $355.6 million for the fourth quarter of 2004, up 39 percent from the fourth quarter of 2003. This growth was driven primarily by higher product sales from our HIV product franchise that includes Viread(R) (tenofovir disoproxil fumarate), Emtriva(R) (emtricitabine) and Truvada(R) (emtricitabine and tenofovir disoproxil fumarate). HIV product sales were $261.7 million in the fourth quarter of 2004, a 45 percent increase from HIV product sales of $180.8 million for the same period in 2003. Sales of Viread were $198.8 million in the fourth quarter of 2004, up from $176.8 million in the fourth quarter of 2003, an increase of 12 percent. U.S. sales of Viread were $103.9 million, while sales outside the United States totaled $94.9 million. Overall Viread sales growth was led by a 40 percent increase in European volume partially offset by a 14 percent volume decrease in the United States, which was primarily driven by patients switching from a Viread-containing regimen to one containing Truvada. A favorable currency environment in Europe further increased Viread sales in the fourth quarter of 2004 by $6.2 million compared to the same quarter last year. Sales of Truvada and Emtriva were $49.7 million and $13.2 million, respectively, for the fourth quarter of 2004. AmBisome(R) (amphotericin B) liposome for injection sales for the fourth quarter of 2004 were $55.0 million, a slight increase of one percent compared to the fourth quarter of 2003. Actual sales volume of AmBisome in Europe increased by 2 percent when compared to the same period last year. This increase in volume along with the favorable foreign exchange environment in Europe, and higher sales volumes in Latin America and Asia, were partially offset by lower pricing in some regions. Sales of Hepsera(R) (adefovir dipivoxil 10 mg) totaled $35.9 million for the fourth quarter of 2004, up 127 percent from $15.8 million in the same quarter of 2004 due to the growth in European sales since the launch of Hepsera in 2003.

"We are extremely pleased with the performance of our product portfolio, in particular our HIV franchise, over the course of 2004," said John C. Martin, PhD, President and Chief Executive Officer of Gilead Sciences. "For the first time, full-year sales from our products surpassed $1 billion. This achievement, along with our continued focus on disciplined spending, resulted in record cash flow for the year 2004 of over $511 million."

For the fourth quarter of 2004, royalty and contract revenues resulting from collaborations with corporate partners totaled $14.0 million, compared to $7.9 million in the fourth quarter of 2003. These revenues primarily relate to royalties on sales of Tamiflu(R) (oseltamivir phosphate) by F. Hoffmann-La Roche and royalties on sales of AmBisome in the United States by Gilead's co-promotion partner, Fujisawa Healthcare.

Research and development (R&D) expenses for the fourth quarter of 2004 were $70.2 million, compared to $58.9 million for the same quarter in 2003. 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 fourth quarter of 2003 of $5.6 million have been reclassified from SG&A to R&D to be consistent with the current period presentation. The higher expenses during the fourth quarter of 2004 are primarily attributable to increased headcount as well as significant research and license fees paid by Gilead in relation to its hepatitis C collaboration agreements with Genelabs Technologies and Achillion Pharmaceuticals.

SG&A expenses for the fourth quarter of 2004 were $85.4 million, compared to $73.1 million for the same quarter of 2003 after the phase IV clinical trial reclassification of $5.6 million to R&D expenses. The higher expenses are due primarily to increased global marketing efforts as well as the timing of certain international medical conferences during the fourth quarter of 2004.

The net foreign exchange impact on pre-tax earnings, including revenue and expenses generated from outside the United States and hedging activity, was a favorable $8.1 million over the fourth quarter of 2003 and a favorable $31.1 million over the full year 2003, due primarily to stronger European currencies relative to the U.S. dollar.

Full Year 2004 Financial Results

Gilead also reported its results of operations for the year ended December 31, 2004. Total net revenues for the year were $1.3 billion, an increase of 53 percent compared to total net revenues of $867.9 million in 2003. Total revenues recorded in fiscal year 2004 included net product sales of $1.2 billion and aggregate contract and royalty revenues of $82.4 million. This compares to net product sales of $836.3 million and aggregate contract and royalty revenues of $31.5 million for 2003. Total product sales from our HIV franchise were $908.4 million for the fiscal year 2004 versus $576.5 million for fiscal year 2003. HIV product sales in 2004 were $27.4 million higher compared to 2003 due to the favorable European currency environment, the majority of which relates to Viread sales. Sales of Viread for the year ended December 31, 2004 were $782.9 million, up 38 percent from $566.5 million for the year ended December 31, 2003. Product sales in 2004 for Emtriva and Truvada were $57.6 million and $67.9 million, respectively. AmBisome sales for the year ended December 31, 2004 were $211.7 million, a 7 percent increase over the year ended December 31, 2003. AmBisome sales for 2004 were $16.3 million higher due to the favorable currency environment compared to 2003. Sales of Hepsera totaled $112.5 million for the year ended December 31, 2004, up 123 percent from $50.4 million for the same period in 2003.

Net income for the year ended December 31, 2004 was $449.4 million, or $0.99 per diluted share, compared to the net loss for the year ended December 31, 2003 of $72.0 million, or $0.18 per diluted share. For the year ended December 31, 2004, non-GAAP net income was $441.4 million, or $0.96 per diluted share, which excludes the impact of the $20.6 million pre-tax gain related to our warrants in Eyetech Pharmaceuticals, Inc., recorded in the first quarter; and the $7.4 million make-whole payment made as a result of the redemption of our $345.0 million 2% convertible senior debt in the fourth quarter. This compares to non-GAAP net income of $302.8 million, or $0.71 per diluted share for the year ended December 31, 2003, after excluding the charge of $488.6 million for in-process research and development associated with the acquisition of Triangle in the first quarter; the $13.2 million reimbursement of research and development expenses from the settlement of a contractual dispute with a vendor recorded during the third quarter; the $10.9 million fourth quarter asset impairment charges and write-downs; and the $111.6 million income tax benefit recorded during the fourth quarter of 2003.

Research and development expenses for the year ended December 31, 2004 were $223.6 million, compared to $181.8 million, which includes the reclassification of phase IV clinical trial expenses to R&D of $16.9 million for the year ended December 31, 2003. Excluding a $13.2 million vendor contract settlement, R&D expenses for the year ended December 31, 2003 would have been $195.0 million. The higher expenses during 2004 are primarily attributable to increased headcount, clinical trials associated with the development of Emtriva and Truvada, as well as significant research and license fees paid by Gilead in relation to two hepatitis C collaboration agreements signed in the fourth quarter of 2004.

Selling, general and administrative expenses for the year ended December 31, 2004 were $302.8 million compared to $233.3 million for the year ended December 31, 2003, which includes the reclassification of phase IV clinical trial expenses to R&D of $16.9 million. The significant increase in expenses is primarily due to Gilead's increased global marketing efforts, the expansion of Gilead's U.S. and European sales forces and infrastructure investments required to support the growth of the business.

As of December 31, 2004, the Company had cash, cash equivalents and marketable securities of $1.25 billion, compared to $707.0 million at December 31, 2003. The increase in cash, cash equivalents and marketable securities is primarily attributable to the $511.4 million of operating cash flow generated during 2004.

Corporate Highlights

In November, the Company completed the redemption of its 2% convertible senior notes due 2007. Gilead called for the full redemption of the outstanding notes on October 6, 2004. The completion of this redemption reduced Gilead's long-term debt by $345.0 million and resulted in the issuance of 14.7 million shares of common stock upon conversion of the notes.

Product and Pipeline Highlights

"In addition to our strong financial performance, Gilead achieved several key milestones in the fourth quarter of 2004, rounding out a year of significant accomplishments," continued Dr. Martin. "We are now one step closer to achieving marketing approval for Truvada in the European Union and have announced a very significant and pioneering joint venture with Bristol-Myers Squibb to further improve HIV therapies for patients by developing a once-daily antiretroviral fixed-dose regimen. In addition, our recent agreements with Genelabs and Achillion presents us with exciting opportunities to accelerate the development of new compounds for the treatment of hepatitis C."

HIV/AIDS Franchise

Also in October, Gilead announced the presentation of interim 24-week data from an ongoing clinical trial (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. The data were presented in a late-breaker presentation at the 44th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Washington D.C.

In November, the Company announced that the European Committee for Medicinal Products for Human Use (CHMP), the scientific committee of the European Medicines Agency (EMEA), recommended granting a Marketing Authorisation for Truvada in the 25 member states of the European Union. The European Commission generally follows the CHMP recommendation and grants a final Marketing Authorisation within a few months following a positive recommendation.

In December, Gilead and Bristol-Myers Squibb announced details of a joint venture to develop and commercialize the fixed-dose combination of Bristol-Myers Squibb's Sustiva(R) (efavirenz) and Gilead's Truvada in the United States.

Hepatitis Franchise

In early November, Gilead announced positive 144-week safety and efficacy data from a clinical trial (Study 437) of Hepsera in patients with chronic hepatitis B at the 55th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in Boston, Massachusetts.

In late November, Gilead and Achillion Pharmaceuticals announced that the companies signed an exclusive agreement granting Gilead worldwide rights for the research, development and commercialization of certain Achillion compounds for the treatment of infection with the hepatitis C virus (HCV).

In December, GlaxoSmithKline (GSK), Gilead's marketing partner for Hepsera in Asia and Latin America, announced that it had launched Hepsera in Japan. Gilead receives royalties for Hepsera sales in the countries where GSK markets the drug. Hepsera is now marketed by Gilead in 20 countries, including the United States, Australia and 15 countries of the European Union, and by GSK in six countries in Asia.

Notes:

(1) Certain prior period amounts associated with phase IV clinical
    trial expenses totaling $5.6 million and $16.9 million for the
    quarter and year ended December 31, 2003, respectively, have been
    reclassified from selling, general and administrative to research
    and development to be consistent with the current period
    presentation.

(2) During the fourth quarter of 2003, Gilead recorded non-cash
    impairment charges against certain long-lived assets of $10.2
    million and $0.7 million related to other asset write-downs
    charged to cost of goods sold. These charges were primarily driven
    by the decision to terminate liposomal research and development
    activities and discontinue the DaunoXome product line. In
    addition, Gilead recorded an income tax benefit of $111.6 million
    related to the reduction of the valuation allowance on certain of
    our net deferred tax assets.

(3) In November 2004, in conjunction with the redemption of the
    Company's $345.0 million 2% convertible senior debt, Gilead made a
    make-whole payment equal to $60 per $1,000 principal value less
    any interest actually paid or accrued from debt issuance to
    redemption.

(4) Net income (loss) 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 September 3, 2004.

(5) In accordance with Statement of Financial Accounting Standard
    No. 128, using the If-Converted Method, interest expense related
    to convertible debt of $9.2 million has been added back to net
    income for purposes of calculating diluted net income per share
    for the year ended December 31, 2004, and $4.2 million for the
    quarter ended December 31, 2003. The shares used in the
    calculation of net income per diluted share for the year ended
    December 31, 2004 includes the effect of 19.3 million stock
    options outstanding, and the pro-rated 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 quarter ended
    December 31, 2003 includes the effect of 19.3 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.

Notes:

(1) The adjustment reflects the make-whole payment related to the
    redemption of Gilead's $345.0 million 2% convertible senior debt,
    Gilead made a make-whole payment equal to $60 per $1,000 principal
    value less any interest actually paid or accrued from debt
    issuance to redemption.

(2) The non-GAAP results for the three months ended December 31,
    2003 exclude the non-cash impairment charges against certain
    long-lived assets of $10.2 million and $0.7 million related to
    other asset write-downs charged to cost of goods sold. These
    charges were primarily driven by the decision to terminate
    liposomal research and development activities and discontinue the
    DaunoXome product line. The non-GAAP results also exclude an
    income tax benefit of $111.6 million related to the reduction of
    the valuation allowance on certain of our net deferred tax assets.

(3) Certain prior period amounts associated with phase IV clinical
    trial expenses totaling $5.6 million for the three months ended
    December 31, 2003 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 September 3, 2004.

(5) In accordance with Statement of Financial Accounting Standard
    No. 128, using the If-Converted Method, interest expense related
    to convertible debt of $0.7 million and $4.2 million has been
    added back to net income for purposes of calculating diluted net
    income per share for the three months ended December 31, 2004 and
    2003, respectively. The shares used in the calculation of net
    income per diluted share for the three months ended December 31,
    2004 includes the effect of 19.9 million stock options
    outstanding, and the pro-rated 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 three months ended December 31, 2003
    includes the effect of 19.3 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.

    redemption of our $345.0 million 2% convertible senior debt.

(2) The non-GAAP results for the year ended December 31, 2003
    exclude the first quarter in-process research and development

    quarter reimbursement to Gilead of $13.2 million of research and
    development expenses resulting from the settlement of a
