News & Events

Cambridge, MA, February 9, 2005 -- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today reported consolidated financial results for the quarter and year ending December 31, 2004. The Company also provided its full year 2005 financial guidance and outlook.

“Vertex enters 2005 with an improved operating profile and is financially stronger than a year ago,” stated Ian Smith, Senior Vice President and Chief Financial Officer of Vertex Pharmaceuticals. “We set aggressive financial goals for 2004 and achieved all those goals. We significantly increased our total revenue base and reduced our loss. Additionally, we improved our capital structure by deferring significant debt obligations to 2011. We expect the financial achievements and trends to continue in 2005, resulting in an exciting year – a year focused on our clinical pipeline.”

Full Year 2004 Results
For the year ending December 31, 2004, the Company’s GAAP net loss was $166.2 million, or $2.12 per share, compared to a GAAP net loss of $196.8 million, or $2.56 per share, for the year ending December 31, 2003. The GAAP net loss for 2004 and 2003 includes restructuring and other charges of $17.6 million and $91.8 million, respectively. The 2003 GAAP net loss also includes a gain on sale of assets of $70.3 million.

Excluding restructuring and other charges and gains, the loss for the year ending December 31, 2004 was $145.2 million, or $1.85 per share, compared to a loss of $174.6 million, or $2.27 per share, for the year ending December 31, 2003. The reduced loss was principally the result of increased revenues.

Total revenues for the year ending December 31, 2004 were $102.7 million, which represents an increase of $33.6 million, or 49%, compared to $69.1 million in 2003. This increase is primarily due to new collaborative revenue and milestone payments, and increased HIV product royalties from the sales of Lexiva® in the U.S.

Research and development expenses for the year ending December 31, 2004 were $192.2 million compared to $199.6 million in 2003. Sales, general and administrative expenses for the year ending December 31, 2004 were $42.1 million, compared to $39.1 million in 2003. Other interest expense, net, for the year ending December 31, 2004 was $8.0 million compared to $1.9 million in 2003.

At December 31, 2004, Vertex had approximately $392.3 million in cash, cash equivalents and available for sale securities, $232.4 million in convertible debt due February 2011 and $82.6 million in convertible debt due September 2007.

Fourth Quarter 2004 Results
For the fourth quarter of 2004, the Company’s GAAP net loss was $42.8 million, or $0.54 per share, compared to a GAAP net loss of $41.0 million, or $0.53 per share, for the fourth quarter of 2003. The net loss for the fourth quarter of 2004 included a restructuring and other expense of $12.4 million and for the corresponding period in 2003 included a restructuring and other expense of $1.4 million.

Excluding restructuring and other charges, the loss for the fourth quarter of 2004 was $30.4 million, or $0.38 per share, compared to a loss of $39.6 million, or $0.51 per share, for the quarter ending December 31, 2003. That reduced loss was principally the result of increased revenues, which were significantly greater than the increases in research and development expense.

Total revenues for the fourth quarter of 2004 were $39.8 million, which represents an increase of $18.5 million from $21.4 million in 2003. Total revenue included $33.5 million in collaborative R&D revenue in the fourth quarter of 2004 compared to $18.3 million in 2003. The increase includes $9.1 million of revenue recognized from milestone payments received from pharmaceutical collaborators. The Company also recorded $6.3 million in HIV product royalties primarily driven from sales of Lexiva® and Telzir® compared to $3.1 million in the corresponding period in 2003.

Research and development expenses for the fourth quarter of 2004 were $54.2 million, compared to $48.3 million in 2003. This principally reflects increased clinical activity and preparation for significant clinical studies to commence in early 2005. Sales, general and administrative expenses for the quarter ending December 31, 2004 were $11.7 million, compared to $10.5 million in 2003.

During the fourth quarter of 2004, Vertex recorded a $12.4 million charge for restructuring and other expense relating to a real estate lease. This charge reflects a revision of key estimates and assumptions in identifying and securing sub-tenants for a real estate lease, and an imputed interest charge for the related balance sheet liability.

Pralnacasan Update
Vertex today disclosed that Sanofi Aventis has given notice that it is terminating its research, development and commercialization agreement with Vertex pertaining to pralnacasan, a development stage ICE inhibitor. Non-clinical toxicology studies pertaining to pralnacasan are ongoing. Upon termination of the agreement, worldwide rights to pralnacasan will revert to Vertex.

Full Year 2005 Financial Guidance
This section contains forward-looking guidance about the financial outlook for Vertex Pharmaceuticals Incorporated. Financial guidance for 2005 is provided on a non-GAAP basis and excludes any charges or gains. Excluded charges will include certain types of stock-based compensation incurred as a result of the adoption of Financial Accounting Standards Board Statement No. 123^®, “Share-Based Payments” in July 2005. In 2004 and 2003, Vertex engaged in activities that resulted in charges related to an operational restructuring and a decision not occupy a leased facility. The liability associated with the estimated net ongoing obligation will be reviewed quarterly and additional credits or charges may be recorded, as changes in circumstances require.

Loss: Vertex expects that the full year 2005 loss will be in the range of $125 to $135 million, before any charges and gains. Vertex anticipates a loss, before charges and gains, for the first quarter of 2005 in the range of $46 to $49 million.

Revenues: Vertex expects that full year 2005 total revenue will be in the range of $150 to $160 million. This is comprised of:

• HIV product royalties of $25 to $29 million,
• Approximately $100 million of collaborative R&D revenues from existing collaborations, which includes:
  • $90 million in contracted collaborative R&D funding, and
  • approximately $10 million of revenue related to milestone payments from existing collaborations.
• The Company has conducted discussions with pharmaceutical companies regarding strategic research and product development agreements, and the Company expects the successful conclusion of those or other such discussions to result in an additional $20 to $30 million in revenue.

Research and Development (R&D) Expense: The Company projects that R&D expense will be in the range of $225 to $240 million for 2005. The forecasted increase as compared to 2004 is driven by increased clinical development investment as Vertex advances its core programs.

Sales, General and Administrative (SG&A) Expense: Vertex expects SG&A expense to be in the range of $42 to $46 million in 2005.

Cash, Cash Equivalents and Available for Sale Securities: Vertex expects cash, cash equivalents and available for sale securities to be in excess of $250 million at the end of 2005.

2005 Outlook
“ Strong performance across all aspects of our business – finance, commercial, clinical and discovery – in 2004 has provided a foundation upon which we can pursue important product development objectives in 2005,” stated Joshua Boger, Ph.D., Chairman and CEO of Vertex. “As we seek to advance Vertex’s core product opportunities in the clinic this year, we see numerous potential catalysts for value creation. We anticipate significant clinical newsflow from our leading HCV therapies.”

“In particular, we expect to report data from a Phase Ib study of our oral HCV protease inhibitor, VX-950, in the second quarter of the year, which we believe may begin to distinguish clinically the potency of this product candidate,” said Dr. Boger. “The Phase Ib study has been rigorously designed and is blinded to the investigators conducting the trial and to Vertex. The Company plans to complete the first interim analysis, which will include all on-treatment data from all three dose groups of HCV-infected patients, in the second quarter of 2005.”

“We also anticipate that by the end of the year, we will define the registration path forward for merimepodib (MMPD),” Dr. Boger added. “Together, VX-950 and MMPD represent potential new therapeutic options that could enhance or change the standard of care for the treatment of HCV.”

“ In 2005, we will also focus our development investment on advancing our oral anti-cytokine product candidates targeting inflammatory diseases,” continued Dr. Boger. “Based on results from important safety and biomarker studies, we plan to initiate a 200+ patient Phase II study of our p38 MAP kinase inhibitor, VX-702, in patients with rheumatoid arthritis. In addition, we are conducting a Phase IIa study of our lead ICE inhibitor, VX-765, in psoriasis. We expect that these studies will begin to define the future clinical and commercial role of these product opportunities.”

Dr. Boger continued, “Last year, new collaborations had a positive effect on our business. In 2005, we will continue to pursue new collaborations that could support the development and commercialization of our proprietary compounds as well as support our discovery organization. In addition, we are looking forward to continued progress with products being developed in collaboration with major pharmaceutical companies, including VX-680, a novel Aurora kinase inhibitor for the treatment of cancer, which is beginning broad Phase I development with Merck. Also in cancer, we expect our collaborator Novartis to complete preclinical development of VX-322, a novel Flt-3/c-kit inhibitor.”

Note 2: For the three and twelve months ended December 31, 2004 and 2003, the Company incurred restructuring and other expense charges. The charge for the three and twelve months ending December 31, 2004 was $12.4 million and $17.6 million, respectively, and relates to estimated incremental net ongoing lease obligations associated with a real estate lease as well as the imputed interest costs relating to the restructuring and other expense liability. For the three and twelve months ended December 31, 2003 the Company recorded $1.4 million and $91.8 million, respectively. Restructuring and other expense for the twelve months ended December 31, 2003 includes an estimate of the net ongoing lease obligation associated with a decision not to occupy a facility, operational restructuring charges and $6.0 million of lease operating expense incurred prior to the decision not to occupy the space. This expense has been estimated in accordance with FASB 146 “Accounting for Costs Associated with Exit or Disposal Activities” and is reviewed quarterly for changes in circumstances.

Note 3: The Company sold certain assets and liabilities of the Discovery Tools and Services business in March and December 2003, respectively. In October 2001, the FASB issued FASB 144 “Accounting for the Impairment of Long-Lived Assets” (“SFAS 144”). SFAS 144 provides a single accounting model for long-lived assets to be disposed of. The combination of the assets sold in March 2003 and in December 2003 represents a component of the Company’s business that, beginning in 2002, had separately identifiable cash flows. As such, pursuant to SFAS No. 144, the tables presented in this release give effect to the disposition of the assets sold in March and December 2003, accounting for such assets as discontinued operations. For the three months ended December 31, 2003 the Company recorded a loss from discontinued operations of $23,000 while total income for the twelve months ended December 31, 2003 was $69.6 million, including a gain on the sale of assets.
