Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Basis of Presentation

        The accompanying condensed consolidated financial statements are unaudited and have been prepared by Vertex Pharmaceuticals Incorporated ("Vertex" or the "Company") in accordance with accounting principles generally accepted in the United States of America ("GAAP").

        The condensed consolidated financial statements reflect the operations of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.

        Certain information and footnote disclosures normally included in the Company's annual financial statements have been condensed or omitted. The interim financial statements, in the opinion of management, reflect all normal recurring adjustments (including accruals) necessary for a fair presentation of the financial position and results of operations for the interim periods ended June 30, 2009 and 2008.

        The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the fiscal year, although the Company expects to incur a substantial loss for the year ending December 31, 2009. These interim financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2008, which are contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2008 that was filed with the Securities and Exchange Commission (the "SEC") on February 17, 2009.

        On March 12, 2009, Vertex acquired ViroChem Pharma Inc. ("ViroChem"). The Company consolidated ViroChem's operating results with those of Vertex beginning on the date of the acquisition. See Note 10, "Acquisition of ViroChem Pharma Inc.," for additional information regarding the acquisition.

        In accordance with Financial Accounting Standards Board ("FASB") Statement No. 165, "Subsequent Events," the Company has evaluated subsequent events through August 10, 2009, the date of issuance of the condensed consolidated financial statements. During this period, the Company did not have any material recognizable subsequent events. However, the Company did have a nonrecognizable subsequent event related to the amendment of its license, development and commercialization agreement with Mitsubishi Tanabe Pharma Corporation on July 30, 2009. See Note 17, "Subsequent Event," for additional information regarding the amendment.

2. Accounting Policies

Reclassification in the Preparation of Financial Statements

        Certain amounts in prior period condensed consolidated financial statements have been reclassified to conform to the current presentation. The reclassifications had no effect on the reported net loss.

Basic and Diluted Net Loss per Common Share

        Basic net loss per common share is based upon the weighted-average number of common shares outstanding during the period, excluding restricted stock that has been issued but is not yet vested. Diluted net loss per common share is based upon the weighted-average number of common shares outstanding during the period plus additional weighted-average common equivalent shares outstanding during the period when the effect is dilutive. Common equivalent shares result from the assumed exercise of outstanding stock options (the proceeds of which are then assumed to have been used to

repurchase outstanding stock using the treasury stock method), the assumed conversion of convertible notes and vesting of unvested restricted shares of common stock. Common equivalent shares have not been included in the net loss per common share calculations because the effect would have been anti-dilutive. Total potential gross common equivalent shares consisted of the following:

Conversion price (per share)

  $ 23.14   $ 23.14  

Unvested restricted shares

    1,778     1,943  

Stock-based Compensation Expense

        The Company records stock-based compensation expense in accordance with FASB Statement No. 123(R), "Share-Based Payment" ("SFAS 123(R)"). SFAS 123(R) requires companies to expense the fair value of employee stock options and other forms of stock-based employee compensation over the employees' service periods or the derived service period for awards with market conditions. Compensation expense is determined based on the fair value of the award at the grant date, including estimated forfeitures, and is adjusted to reflect actual forfeitures and the outcomes of certain conditions. Please refer to Note 3, "Stock-based Compensation Expense," for further information.

Research and Development Expenses

        All research and development expenses, including amounts funded by research and development collaborations, are expensed as incurred. Pursuant to Emerging Issues Task Force ("EITF") Issue No. 07-3, "Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future Research and Development Activities," the Company defers and capitalizes nonrefundable advance payments made by the Company for research and development activities until the related goods are delivered or the related services are performed.

        Research and development expenses are comprised of costs incurred by the Company in performing research and development activities, including salary and benefits; stock-based compensation expense; laboratory supplies and other direct expenses; contractual services, including clinical trial and pharmaceutical development costs; commercial supply investment in telaprevir; and infrastructure costs, including facilities costs and depreciation expense. The Company evaluates periodically whether a portion of its commercial supply investment may be capitalized as inventory. Generally, inventory may be capitalized if it is probable that future revenues will be generated from the sale of the inventory and that these revenues will exceed the cost of the inventory. The Company is continuing to expense all of its commercial supply investment due to the high risk inherent in drug development.

2. Accounting Policies (Continued)

        The Company's collaborators have funded portions of the Company's research and development programs related to specific drug candidates and research targets, including telaprevir, in the three and six months ended June 30, 2009 and 2008. The Company's collaborative and other research and development revenues were $13.1 million and $59.7 million, respectively, for the three months ended June 30, 2009 and 2008. The Company's collaborative and other research and development revenues were $31.0 million and $90.5 million, respectively, for the six months ended June 30, 2009 and 2008. The Company's research and development expenses allocated to programs in which a collaborator funded at least a portion of the research and development expenses were approximately $37 million and approximately $35 million, respectively, for the three months ended June 30, 2009 and 2008, and approximately $86 million and approximately $70 million, respectively, for the six months ended June 30, 2009 and 2008.

Restructuring Expense

        The Company records costs and liabilities associated with exit and disposal activities, as defined in FASB Statement No. 146, "Accounting for Costs Associated with Exit or Disposal Activities" ("SFAS 146"), based on estimates of fair value in the period the liabilities are incurred. In periods subsequent to initial measurement, changes to the liability are measured using the credit-adjusted risk-free discount rate applied in the initial period. Liabilities are evaluated and adjusted as appropriate at least on a quarterly basis for changes in circumstances.

Revenue Recognition

        The Company recognizes revenues in accordance with SEC Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements," as amended by SEC Staff Accounting Bulletin No. 104, "Revenue Recognition," and EITF Issue No. 00-21, "Revenue Arrangements with Multiple Deliverables" ("EITF 00-21").

        The Company's revenues are generated primarily through collaborative research, development and/or commercialization agreements. The terms of these agreements typically include payment to the Company of one or more of the following: nonrefundable, up-front license fees; funding of research and/or development efforts; milestone payments; and royalties on product sales.

        Agreements containing multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the collaborator and whether there is objective and reliable evidence of the fair value of the undelivered obligation(s). The consideration received is allocated among the separate units either on the basis of each unit's fair value or using the residual method, and the applicable revenue recognition criteria are applied to each of the separate units.

        The Company recognizes revenues from nonrefundable, up-front license fees on a straight-line basis over the contracted or estimated period of performance, which is typically the research or development term. Research and development funding is recognized as earned, ratably over the period of effort.

2. Accounting Policies (Continued)

        Substantive milestones achieved in collaboration arrangements are recognized as earned when the corresponding payment is reasonably assured, subject to the following policies in those circumstances where the Company has obligations remaining after achievement of the milestone:

    In those circumstances where collection of a substantive milestone payment is reasonably assured, the Company has remaining obligations to perform under the collaboration arrangement and the Company has sufficient evidence of the fair value for the performance of its remaining obligations, management considers the milestone payment and the remaining obligations to be separate units of accounting. In these circumstances, the Company uses the residual method under EITF 00-21 to allocate revenues among the milestones and the remaining obligations.

    In those circumstances where collection of a substantive milestone payment is reasonably assured and the Company has remaining obligations to perform under the collaboration arrangement, but the Company does not have sufficient evidence of the fair value for its remaining obligations, management considers the milestone payment and the remaining obligations under the contract as a single unit of accounting. If the collaboration does not require specific deliverables at specific times or at the end of the contract term, but rather, the Company's obligations are satisfied over a period of time, substantive milestone payments are recognized over the period of performance. This typically results in a portion of the milestone payment being recognized as revenue on the date the milestone is achieved equal to the applicable percentage of the performance period that has elapsed as of the date the milestone is achieved, with the balance being deferred and recognized over the remaining period of performance.

        At the inception of each agreement that includes milestone payments, the Company evaluates whether each milestone is substantive on the basis of the contingent nature of the milestone, specifically reviewing factors such as the scientific and other risks that must be overcome to achieve the milestone, as well as the level of effort and investment required. Milestones that are not considered substantive and that do not meet the separation criteria are accounted for as license payments and recognized on a straight-line basis over the remaining period of performance.

        Payments received or reasonably assured after performance obligations are met completely are recognized as earned.

        Royalty revenues typically are recognized based upon actual and estimated net sales of licensed products in licensed territories, as provided by the licensee, and generally are recognized in the period the sales occur. The Company reconciles and adjusts for differences between actual royalty revenues and estimated royalty revenues in the quarter they become known. These differences have not historically been significant.

        In the circumstance where the Company has sold its rights to future royalties under a license agreement and also maintains continuing involvement in the royalty arrangement (but not significant continuing involvement in the generation of the cash flows due to the purchaser), the Company defers recognition of the proceeds it receives for the royalty stream and recognizes these deferred revenues over the life of the license agreement. The Company recognizes these deferred revenues pursuant to the units-of-revenue method in accordance with EITF Issue No. 88-18, "Sales of Future Revenues" ("EITF 88-18"). Under this method, the amount of deferred revenues to be recognized as royalty

2. Accounting Policies (Continued)


revenues in each period is calculated by multiplying the following: (1) the royalty payments due to the purchaser for the period by (2) the ratio of the remaining deferred revenue amount to the total estimated remaining royalty payments due to the purchaser over the term of the agreement.

Debt Issuance Costs and Royalty Sale Transaction Expenses

        Debt issuance costs incurred to complete the Company's convertible senior subordinated note offering are deferred and included in other assets on the condensed consolidated balance sheets. The debt issuance costs are amortized based on the effective interest method over the term of the related debt issuance. The amortization expense related to the debt issuance costs is included in interest expense on the condensed consolidated statements of operations.

        The Company defers direct and incremental costs associated with its sale of its rights to future HIV royalties by analogy to FASB Technical Bulletin No. 90-1, "Accounting for Separately Priced Extended Warranty and Product Maintenance Contracts." These costs are included in other assets on the condensed consolidated balance sheets and are amortized based on the units-of-revenue method in the same manner and over the same period in which the related deferred revenues are recognized as royalty revenues. The amortization expense related to these transaction expenses is included in royalty expenses on the condensed consolidated statements of operations.

Business Combinations

        Under FASB Statement No. 141 (Revised 2007), "Business Combinations" ("SFAS 141(R)"), which applies to transactions that occur after January 1, 2009, the Company assigns the value of the consideration transferred to acquire a business to the tangible assets and identifiable intangible assets acquired and liabilities assumed on the basis of their fair values at the date of acquisition. The Company assesses the fair value of assets, including intangible assets such as in-process research and development, using a variety of methods including present-value models. Each asset is measured at fair value in accordance with FASB Statement No. 157, "Fair Value Measurements" ("SFAS 157"), from the perspective of a market participant. The method used to estimate the fair values of in-process research and development assets reflects significant assumptions regarding the estimates a market participant would make in order to evaluate an asset, including a market participant's assumptions regarding the probability of completing in-process research and development projects, which would require obtaining regulatory approval for marketing of the associated drug candidate; a market participant's estimates regarding the timing of and the expected costs to complete in-process research and development projects; a market participant's estimates of future cash flows from potential product sales; and the appropriate discount rates for a market participant. In accordance with SFAS 141(R), transaction costs and restructuring costs associated with the transaction are expensed as incurred.

In-process Research and Development Assets

        In-process research and development assets acquired in a business combination initially are recorded at fair value and accounted for as indefinite-lived intangible assets in accordance with FASB Statement No. 142, "Goodwill and Other Intangible Assets," as amended by SFAS 141(R). These assets are maintained on the Company's condensed consolidated balance sheets until either the project underlying them is completed or the assets become impaired. If a project is completed, the carrying

value of the related intangible asset is amortized over the remaining estimated life of the asset beginning in the period in which the project is completed. If a project becomes impaired or is abandoned, the carrying value of the related intangible asset is written down to its fair value and an impairment charge is taken in the period in which the impairment occurs. In-process research and development assets will be tested for impairment on an annual basis during the fourth quarter, or earlier if impairment indicators are present.

Goodwill

        The difference between the purchase price and the fair value of assets acquired and liabilities assumed in a business combination is allocated to goodwill. Goodwill will be evaluated for impairment on an annual basis during the fourth quarter, or earlier if impairment indicators are present.

3. Stock-based Compensation Expense

        At June 30, 2009, the Company had four stock-based employee compensation plans: the 1991 Stock Option Plan (the "1991 Plan"), the 1994 Stock and Option Plan (the "1994 Plan"), the 1996 Stock and Option Plan (the "1996 Plan") and the 2006 Stock and Option Plan (the "2006 Plan" and together with the 1991 Plan, the 1994 Plan and the 1996 Plan, collectively, the "Stock and Option Plans") and one Employee Stock Purchase Plan (the "ESPP"). On May 15, 2008, the Company's stockholders approved an increase in the number of shares of common stock authorized for issuance under the 2006 Plan of 6,600,000, to a total of 13,902,380 shares of common stock, and an increase in the number of shares of common stock authorized for issuance under the ESPP of 2,000,000. On May 14, 2009, the Company's stockholders approved an increase in the number of shares of common stock authorized for issuance under the 2006 Plan of 7,700,000, to a total of 21,602,380 shares of common stock. In connection with the Stock and Option Plans, the Company issues stock options and restricted stock awards with service conditions, which are generally the vesting periods of the awards. The Company also issues to certain members of senior management restricted stock awards that vest upon the earlier of the satisfaction of (i) a market or performance condition or (ii) a service condition ("PARS").

        The Company records stock-based compensation expense in accordance with SFAS 123(R). SFAS 123(R) requires companies to recognize share-based payments to employees as compensation expense using the fair value method. The fair value of stock options and shares purchased pursuant to the ESPP is calculated using the Black-Scholes valuation model. The fair value of restricted stock awards typically is based on intrinsic value on the date of grant. Under the fair value recognition provisions of SFAS 123(R), stock-based compensation, measured at the grant date based on the fair value of the award, is recognized as expense ratably over the service period. The expense recognized over the service period includes an estimate of awards that will be forfeited.

        For PARS awards granted in 2008, 2007 and 2006, which vest upon the earlier of the achievement of a market condition or a service condition, a portion of the fair value of the common stock on the date of grant is recognized ratably over a derived service period that is equal to the estimated time to satisfy the market condition. The portion of the fair value of the common stock that is recognized over the derived service period is determined on the basis of the estimated probability that the PARS award will vest as a result of satisfying the market condition. For the PARS awards granted in 2008, 2007 and

3. Stock-based Compensation Expense (Continued)


2006, the derived service period relating to each market condition is shorter than the four-year service-based vesting period of the PARS. The difference between the fair value of the common stock on the date of grant and the value recognized over the derived service period is recognized ratably over the four-year service-based vesting period of the PARS. The stock-based compensation expense recognized over each of the derived service periods and the four-year service periods includes an estimate of awards that will be forfeited prior to the end of the derived service periods or the four-year service periods, respectively. For PARS awards granted in 2009, the shares vest on the fourth anniversary of the grant date, subject to accelerated vesting upon achievement of performance conditions. In accordance with SFAS 123(R), stock-based compensation expense associated with the PARS issued in 2009 is being expensed ratably over the four-year service period.

        The effect of stock-based compensation expense during the three and six months ended June 30, 2009 and 2008 was as follows:

Stock Options

        All stock options awarded during the six months ended June 30, 2009 and 2008 were awarded with exercise prices equal to the fair market value of the Company's common stock on the date the award was granted by the Company's board of directors. Under amendments to the 2006 Plan adopted on May 15, 2008, no options can be issued under the 2006 Plan with an exercise price less than the fair market value on the date of grant.

        The stock options granted during the six months ended June 30, 2008 included options to purchase 536,625 shares of common stock (the "Contingent Options") at an exercise price of $18.93 per share that were granted to the Company's executive officers on February 7, 2008, subject to ratification by the Company's stockholders. At the Company's 2008 Annual Meeting of Stockholders, the stockholders ratified the Contingent Options as part of the Company's proposal to increase the number of shares authorized for issuance under the 2006 Plan. Under SFAS 123(R), the Contingent Options are deemed for accounting purposes to have been granted on May 15, 2008 (the date of ratification by the Company's stockholders), and the grant-date fair value of the Contingent Options is based on a Black-Scholes valuation model based on the fair market value of the Contingent Options on May 15, 2008.

4. Marketable Securities (Continued)

        The Company had marketable securities of $345.4 million and $443.0 million that were all classified as current assets on the condensed consolidated balance sheets as of June 30, 2009 and December 31, 2008, respectively.

        The Company reviews investments in marketable securities for other-than-temporary impairment whenever the fair value of an investment is less than amortized cost and evidence indicates that an investment's carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers the intent to sell, or whether it is more likely than not that the Company will be required to sell, the investment before recovery of the investment's amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, compliance with the Company's investment policy, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2009 and December 31, 2008, the Company did not have any securities with unrealized losses.

        In the three and six months ended June 30, 2009, the Company had proceeds of $171,000 and $345,000, respectively, from sales and maturities of available for sale securities. In the three and six months ended June 30, 2008, the Company had proceeds of $55,000 and $84,000, respectively, from sales and maturities of available for sale securities.

        Realized gains and losses are determined on the specific identification method and are included in interest income on the condensed consolidated statements of operations. There were no gross realized gains and losses for the three and six months ended June 30, 2009. Gross realized gains and losses for the three months ended June 30, 2008 were $378,000 and $306,000, respectively. Gross realized gains and losses for the six months ended June 30, 2008 were $525,000 and $306,000, respectively.

5. Fair Value of Financial Instruments and Nonfinancial Assets

        On January 1, 2008, the Company adopted SFAS 157, which established a framework for measuring the fair value of assets and liabilities pursuant to GAAP and expanded the required disclosure regarding assets and liabilities that are measured at fair value. SFAS 157 became applicable to the Company's financial assets and liabilities on January 1, 2008 and became applicable to the Company's nonfinancial assets and liabilities on January 1, 2009.

        SFAS 157 did not change the standard for determining whether assets and liabilities should be recorded at cost or at fair value. For assets and liabilities required to be disclosed at fair value, SFAS 157 introduced, or reiterated, a number of key concepts that form the foundation of the fair value measurement approach. In accordance with SFAS 157, the fair value of the Company's financial assets and liabilities reflects the Company's estimate of amounts that it would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from sources independent from the Company) and to minimize the use of unobservable inputs (the Company's assumptions about how market participants

would price assets and liabilities). SFAS 157 establishes the following fair value hierarchy for the use of observable inputs and unobservable inputs in valuing assets and liabilities:

    Level 1:   Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
   
Level 2:

 

Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.
   
Level 3:

 

Unobservable inputs based on the Company's assessment of the assumptions that market participants would use in pricing the asset or liability.

        The Company's investment strategy is focused on capital preservation. The Company invests in instruments that meet credit quality standards as outlined in the Company's investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue or type of instrument. Beginning in the fourth quarter of 2007, the Company began to shift its investments to instruments that carry less exposure to market volatility and liquidity pressures. As of June 30, 2009, the majority of the Company's investments are in money market funds and short-term government guaranteed or supported securities.

        As of June 30, 2009, all of the Company's financial assets that were subject to fair value measurements were valued using observable inputs and the Company had no financial liabilities that were subject to fair value measurement. The Company's financial assets valued based on Level 1 inputs consisted of a money market fund and government-sponsored enterprise securities, which are government supported. The Company's money market fund also invests in government-sponsored enterprise securities. The Company's financial assets valued based on Level 2 inputs consisted of commercial paper, which is guaranteed by the FDIC. The Company's investments in commercial paper consist of high-grade investments. During the six months ended June 30, 2009 and 2008, the Company did not record an other-than-temporary impairment charge related to its investments.

        The following table sets forth the Company's financial assets subject to fair value measurements on a recurring basis as of the end of the second quarter of 2009:

        Intangible assets acquired in connection with the Company's acquistion of ViroChem were accounted for in accordance with SFAS 157 as described in Note 10, "Acquisition of ViroChem Pharma Inc." The fair value of these nonfinancial assets was based on Level 3 inputs.

        The Company had $144.0 million outstanding in aggregate principal amount of 4.75% convertible senior subordinated notes due 2013 included on the condensed consolidated balance sheet as of June 30, 2009. At June 30, 2009, these 2013 Notes had a fair value of $216.9 million as obtained from a quoted market source.

7. Income Taxes

        Effective January 1, 2007, the Company adopted the provisions of FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109" ("FIN 48"). At June 30, 2009 and December 31, 2008, the Company had no material unrecognized tax benefits and no adjustments to liabilities or operations were required under FIN 48. The Company does not expect that its unrecognized tax benefits will materially increase within the next twelve months. The Company did not recognize any material interest or penalties related to uncertain tax positions at June 30, 2009 and December 31, 2008.

        The Company files United States federal income tax returns and income tax returns in various state, local, and foreign jurisdictions. The Company is no longer subject to any tax assessment from an income tax examination in the United States before 2007 and any other major taxing jurisdiction for years before 2005, except where the Company has net operating losses or tax credit carryforwards that originate before 2005. The Company completed an examination by the Internal Revenue Service with respect to 2006 in June 2009 with no material change. The Company currently is not under examination by any jurisdiction for any tax year.

8. Restructuring Expense

        In June 2003, Vertex adopted a plan to restructure its operations to coincide with its increasing internal emphasis on advancing drug candidates through clinical development to commercialization. The restructuring was designed to re-balance the Company's relative investments in research and development to better support the Company's long-term strategy. The restructuring plan included a workforce reduction, write-offs of certain assets and a decision not to occupy approximately 290,000 square feet of specialized laboratory and office space in Cambridge, Massachusetts under lease to Vertex (the "Kendall Square Lease"). The Kendall Square Lease commenced in January 2003 and has a 15-year term. In the second quarter of 2005, the Company revised its assessment of its real estate requirements and decided to use approximately 120,000 square feet of the facility subject to the Kendall Square Lease (the "Kendall Square Facility") for its operations, beginning in 2006. The remaining rentable square footage of the Kendall Square Facility currently is subleased to third parties.

        The Company estimates the restructuring expense in accordance with SFAS 146. The restructuring expense incurred in the three and six months ended June 30, 2009 and 2008 relates only to the portion of the building that the Company is not occupying and does not intend to occupy for its operations. The remaining lease obligations, which are associated with the portion of the Kendall Square Facility that the Company occupies and uses for its operations, are recorded as rental expense in the period incurred.

        In estimating the expense and liability under its Kendall Square Lease obligation, the Company estimated (i) the costs to be incurred to satisfy rental and build-out commitments under the lease (including operating costs), (ii) the lead-time necessary to sublease the space, (iii) the projected sublease rental rates and (iv) the anticipated durations of subleases. The Company uses a credit-adjusted risk-free rate of approximately 10% to discount the estimated cash flows. The Company reviews its estimates and assumptions on at least a quarterly basis, and intends to continue such reviews until the termination of the Kendall Square Lease, and will make whatever modifications the Company believes necessary, based on the Company's best judgment, to reflect any changed circumstances. The Company's estimates have changed in the past, and may change in the future, resulting in additional adjustments to the estimate of the liability, and the effect of any such adjustments could be material. Changes to the Company's estimate of the liability are recorded as additional restructuring expense/(credit). In addition, because the Company's estimate of the liability includes the application of a discount rate to reflect the time-value of money, the Company will record imputed interest costs related to the liability each quarter. These costs are included in restructuring expense on the Company's condensed consolidated statements of operations.

        For the three months ended June 30, 2009, the Company recorded restructuring expense of $1.1 million, which was primarily the result of the imputed interest cost relating to the restructuring

9. Equity and Debt Offerings and Debt Exchanges

        On February 24, 2009, the Company completed an offering of 10,000,000 shares of common stock (the "February 2009 Equity Offering"), which were sold at a price of $32.00 per share. This offering resulted in $313.3 million of net proceeds to the Company. The underwriting discount of $6.4 million and other expenses of $0.4 million related to the February 2009 Equity Offering were recorded as an offset to additional paid-in capital.

        On September 23, 2008, the Company completed an offering of 8,625,000 shares of common stock (the "September 2008 Equity Offering"), which were sold at a price of $25.50 per share. This offering resulted in $217.4 million of net proceeds to the Company. The underwriting discount of $2.2 million and other expenses of $0.3 million related to the September 2008 Equity Offering were recorded as an offset to additional paid-in capital.

        On February 19, 2008, the Company completed concurrent offerings of $287.5 million in aggregate principal amount of 4.75% convertible senior subordinated notes due 2013 (the "2013 Notes") and 6,900,000 shares of common stock (the "February 2008 Equity Offering"), which were sold at a price of $17.14 per share.

        The convertible debt offering resulted in net proceeds of $278.6 million to the Company. The underwriting discount of $8.6 million and other expenses of $0.3 million related to the convertible debt offering were recorded as debt issuance costs and are included in other assets on the Company's condensed consolidated balance sheets. The February 2008 Equity Offering resulted in net proceeds of $112.7 million to the Company. The underwriting discount of $5.3 million and other expenses of $0.2 million related to the February 2008 Equity Offering were recorded as an offset to additional paid-in capital.

        The 2013 Notes are convertible, at the option of the holder, into common stock at a price equal to approximately $23.14 per share, subject to adjustment. The 2013 Notes bear interest at the rate of 4.75% per annum, and the Company is required to make semi-annual interest payments on the outstanding principal balance of the 2013 Notes on February 15 and August 15 of each year. The 2013 Notes will mature on February 15, 2013.

9. Equity and Debt Offerings and Debt Exchanges (Continued)

        On or after February 15, 2010, the Company may redeem the 2013 Notes at its option, in whole or in part, at the redemption prices stated in the indenture, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. Holders may require the Company to repurchase some or all of their 2013 Notes upon the occurrence of certain fundamental changes of Vertex, as set forth in the indenture, at 100% of the principal amount of the 2013 Notes to be repurchased, plus any accrued and unpaid interest, if any, to, but excluding, the repurchase date.

        If a fundamental change occurs that is also a specific type of change of control under the indenture, the Company will pay a make-whole premium upon the conversion of the 2013 Notes in connection with any such transaction by increasing the applicable conversion rate on such 2013 Notes. The make-whole premium will be in addition to, and not in substitution for, any cash, securities or other assets otherwise due to holders of the 2013 Notes upon conversion. The make-whole premium will be determined by reference to the indenture and is based on the date on which the fundamental change becomes effective and the price paid, or deemed to be paid, per share of the Company's common stock in the transaction constituting the fundamental change, subject to adjustment.

        The indenture provides the holders of the 2013 Notes with certain remedies if a default occurs under the indenture. If an event of default under the indenture relates solely to the Company's failure to comply with its reporting obligations pursuant to the 2013 Notes, at the election of the Company, the sole remedy of the holders of the 2013 Notes for the first 180 days following such event of default would consist of the right to receive special interest at an annual rate equal to 1.0% of the outstanding principal amount of the 2013 Notes.

        Based on the Company's evaluation of the 2013 Notes in accordance with EITF Issue No. 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock," and FASB Statement No. 133, "Accounting for Derivative Instruments and Hedging Activities," the Company determined that the 2013 Notes contain a single embedded derivative. This embedded derivative relates to potential penalty interest payments that could be imposed on the Company for a failure to comply with its reporting obligations pursuant to the 2013 Notes. This embedded derivative required bifurcation as the feature was not clearly and closely related to the host instrument. The Company has determined that the value of this embedded derivative was nominal as of February 19, 2008, December 31, 2008 and June 30, 2009.

        On June 10, 2009, the Company exchanged 6,601,000 shares of newly-issued common stock for $143.5 million in aggregate principal amount of the 2013 Notes, plus accrued interest. In the exchanges, the Company issued 46 shares of common stock for each $1,000 in principal amount of 2013 Notes. As a result of the exchanges, the Company incurred a non-cash charge of $12.3 million in the second quarter of 2009. This charge is related to the incremental shares issued in the transaction over the number that would have been issued upon conversion of the 2013 Notes under their original terms, at the original conversion rate of approximately 43.22 shares of common stock per $1,000 in principal amount of the 2013 Notes. In addition, accrued interest of $2.1 million and unamortized debt issuance costs of exchanged convertible notes of $3.5 million were recorded as an offset to additional paid-in capital on the Company's condensed consolidated balance sheet.

10. Acquisition of ViroChem Pharma Inc.

        On March 12, 2009, the Company acquired 100% of the outstanding equity of ViroChem, a privately-held biotechnology company based in Canada, for $100.0 million in cash and 10,733,527 shares of the Company's common stock. Vertex acquired ViroChem in order to add two clinical-development stage HCV polymerase inhibitors to Vertex's HCV drug development portfolio. In addition at the time of the acquisition, ViroChem was engaged in additional research stage activities related to viral diseases and was developing an early-stage drug candidate for the treatment of patients with HIV.

        The transaction is being accounted for under the acquisition method of accounting in accordance with SFAS 141(R). Under SFAS 141(R), all of the assets acquired and liabilities assumed in the transaction are recognized at their acquisition-date fair values, while transaction costs and restructuring costs associated with the transaction are expensed as incurred.

Purchase Price

        The $390.6 million purchase price for ViroChem is based on the acquisition-date fair value of the consideration transferred, which was calculated based on the opening price of the Company's common stock of $27.07 per share on March 12, 2009. The acquisition-date fair value of the consideration consisted of the following:

Allocations of Assets and Liabilities

        The Company has allocated the purchase price for ViroChem to net tangible assets and intangible assets, goodwill and a deferred tax liability. The difference between the aggregate purchase price and the fair value of assets acquired and liabilities assumed was allocated to goodwill. The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date:

10. Acquisition of ViroChem Pharma Inc. (Continued)

        Under SFAS 141(R), all $525.9 million of the intangible assets acquired in the ViroChem acquisition relate to in-process research and development assets. These in-process research and development assets primarily relate to ViroChem's two clinical-development stage HCV polymerase inhibitors, VX-222 (formerly VCH-222) and VX-759 (formerly VCH-759), which had estimated fair values of $412.9 million and $105.8 million, respectively. The fair values of VX-222 and VX-759 were measured from the perspective of a market participant in accordance with SFAS 157. In addition, the Company also considered ViroChem's other clinical drug candidates and determined that VCH-286, ViroChem's lead HIV drug candidate, had an estimated fair value of $7.2 million, based on development costs through the acquisition date, and that the other clinical drug candidates had no fair value because the clinical and non-clinical data for those drug candidates did not support further development as of the acquisition date. The Company also considered ViroChem's preclinical programs and other technologies and determined that because of uncertainties related to the safety, efficacy and commercial viability of the potential drug candidates market participants would not ascribe value to these assets.

        If a project is completed, the carrying value of the related intangible asset will be amortized over the remaining estimated life of the asset beginning in the period in which the project is completed. If a project becomes impaired or is abandoned, the carrying value of the related intangible asset will be written down to its fair value and an impairment charge will be taken in the period in which the impairment occurs. The ViroChem intangible assets will be tested for impairment on an annual basis during the fourth quarter, or earlier if impairment indicators are present.

        The deferred tax liability primarily relates to the tax impact of future amortization or impairments associated with the identified intangible assets acquired, which are not deductible for tax purposes.

        The difference between the consideration transferred to acquire the business and the fair value of assets acquired and liabilities assumed was allocated to goodwill. This goodwill relates to the potential synergies from the possible development of combination therapies involving telaprevir and the acquired drug candidates. None of the goodwill is expected to be deductible for income tax purposes. As of June 30, 2009, there were no changes in the recognized amounts of goodwill resulting from the acquisition of ViroChem.

Acquisition-related Expenses, Including Restructuring

        The Company incurred $0 and $7.8 million, respectively, in expenses that are reflected as acquisition-related expenses on the condensed consolidated statement of operations for the three and six months ended June 30, 2009. These costs include transaction expenses and a restructuring charge that was incurred in March 2009 when Vertex determined it would restructure ViroChem's operations in order to focus ViroChem's activities on its HCV development programs. As a result of this restructuring plan, Vertex recorded a $2.1 million expense related to employee severance, benefits and related costs in accordance with SFAS 146. SFAS 146 requires that a liability be recorded for a cost associated with an exit or disposal activity at its fair value in the period in which the liability is incurred. The accrued liability of $2.1 million, which was included in accrued expenses and other current liabilities on the condensed consolidated balance sheet as of March 31, 2009, was paid in the second quarter of 2009.

ViroChem Financial Information

        The results of operations of ViroChem have been included in the condensed consolidated financial statements since the acquisition date. ViroChem had no revenues in the period from the acquisition date to June 30, 2009, and ViroChem's net loss in the period from the acquisition date to June 30, 2009 was immaterial to the Company's condensed consolidated financial results. Pro forma results of operations for the three and six months ended June 30, 2009 and 2008 assuming the acquisition of ViroChem had taken place at the beginning of each period would not differ significantly from Vertex's actual reported results.

11. Sale of HIV Protease Inhibitor Royalty Stream

        In December 1993, the Company and GlaxoSmithKline plc ("GlaxoSmithKline") entered into a collaboration agreement to research, develop and commercialize HIV protease inhibitors, including Agenerase (amprenavir) and Lexiva/Telzir (fosamprenavir calcium). Under the collaboration agreement, GlaxoSmithKline agreed to pay the Company royalties on net sales of drugs developed under the collaboration.

        The Company began earning a royalty from GlaxoSmithKline in 1999 on net sales of Agenerase, in the fourth quarter of 2003 on net sales of Lexiva, and in the third quarter of 2004 on net sales of Telzir. GlaxoSmithKline has the right to terminate its arrangement with the Company without cause upon twelve months' notice. Termination of the collaboration agreement by GlaxoSmithKline will relieve it of its obligation to make further payments under the agreement and will end any license granted to GlaxoSmithKline by the Company under the agreement. In June 1996, the Company and GlaxoSmithKline obtained a worldwide, non-exclusive license under certain G.D. Searle & Co. ("Searle," now owned by Pharmacia/Pfizer) patents in the area of HIV protease inhibition. Searle is paid royalties based on net sales of Agenerase and Lexiva/Telzir.

        On May 30, 2008, the Company entered into a purchase agreement (the "Purchase Agreement") with Fosamprenavir Royalty, L.P. ("Fosamprenavir Royalty") pursuant to which the Company sold, and Fosamprenavir Royalty purchased, the Company's right to receive royalty payments, net of royalty amounts to be earned and due to Searle, arising from sales of Lexiva/Telzir and Agenerase under the Company's 1993 agreement with GlaxoSmithKline, from April 1, 2008 to the end of the term of the collaboration agreement, for a one-time cash payment of $160.0 million. In accordance with the Purchase Agreement, GlaxoSmithKline will make all royalty payments, net of the subroyalty amounts payable to Searle, directly to Fosamprenavir Royalty. The Purchase Agreement also contains other representations, warranties, covenants and indemnification obligations. The Company continues to be obligated for royalty amounts earned and that are due to Searle. The Company has instructed GlaxoSmithKline to pay such amounts directly to Searle as they become due.

        The Company classified the proceeds received from Fosamprenavir Royalty as deferred revenues, to be recognized as royalty revenues over the life of the collaboration agreement because of the Company's continuing involvement in the royalty arrangement over the term of the Purchase Agreement. Such continuing involvement, which is required pursuant to covenants contained in the Purchase Agreement, includes overseeing GlaxoSmithKline's compliance with the collaboration agreement, monitoring and defending patent infringement, adverse claims or litigation involving the

11. Sale of HIV Protease Inhibitor Royalty Stream (Continued)


royalty stream, undertaking to cooperate with Fosamprenavir Royalty's efforts to find a new license partner in the event that GlaxoSmithKline terminates the collaboration agreement, and compliance with the license agreement with Searle, including the obligation to make future royalty payments to Searle. Because the transaction was structured as a non-cancellable sale, the Company does not have significant continuing involvement in the generation of the cash flows due to Fosamprenavir Royalty and there are no guaranteed rates of return to Fosamprenavir Royalty, the Company has recorded the proceeds as deferred revenues pursuant to EITF 88-18.

        The Company recorded $155.1 million, representing the proceeds of the transaction less the net royalty payable to Fosamprenavir Royalty for the period from April 1, 2008 through May 30, 2008, as deferred revenues to be recognized as royalty revenues over the life of the collaboration agreement under the units-of-revenue method. Under this method, the amount of deferred revenues to be recognized as royalty revenues in each period is calculated by multiplying the following: (1) the net royalty payments due to Fosamprenavir Royalty for the period by (2) the ratio of the remaining deferred revenue amount to the total estimated remaining net royalties that GlaxoSmithKline is expected to pay Fosamprenavir Royalty over the term of the collaboration agreement. On May 31, 2008, the Company began recognizing these deferred revenues. In addition, the Company will continue to recognize royalty revenues for the portion of the royalty earned that is due to Searle.

        The Company will recognize royalty expenses in each period based on (i) deferred transaction expenses in the same manner and over the same period in which the related deferred revenues are recognized as royalty revenues plus (ii) the subroyalty paid by GlaxoSmithKline to Searle on net sales of Agenerase and Lexiva/Telzir for the period.

12. Significant Revenue Arrangements

Janssen Pharmaceutica, N.V.

        In June 2006, the Company entered into a collaboration agreement with Janssen Pharmaceutica, N.V. ("Janssen") for the development, manufacture and commercialization of telaprevir, the Company's lead investigative HCV protease inhibitor. Under the agreement, Janssen has agreed to be responsible for 50% of the drug development costs incurred under the development program for the parties' territories (North America for the Company, and the rest of the world, other than the Far East, for Janssen) and has exclusive rights to commercialize telaprevir in its territories including Europe, South America, the Middle East, Africa and Australia. Under the development program for telaprevir, each party is incurring reimbursable drug development costs. Reimbursable costs incurred by Janssen are offset against reimbursable costs incurred by the Company. Amounts that Janssen pays to the Company for reimbursement, after the offset, are recorded as revenues. Accordingly, as Janssen incurs increased costs under the development program, the Company's revenues attributable to the reimbursement are reduced.

        Janssen made a $165.0 million up-front license payment to the Company in July 2006. The up-front license payment is being amortized over the Company's estimated period of performance under the collaboration agreement. Under the agreement, Janssen agreed to make contingent milestone payments, which could total up to $380.0 million if telaprevir is successfully developed, approved and launched as a product. As of June 30, 2009, the Company had earned $100.0 million of these

24

12. Significant Revenue Arrangements (Continued)


contingent milestone payments under the agreement. The remaining $280.0 million in milestones under the Company's agreement with Janssen include $100.0 million related to marketing authorization for telaprevir from the European Medicines Evaluation Agency and $150.0 million related to the launch of telaprevir in the European Union. In July 2009, the Company announced its intention to explore the sale of its rights to these $250.0 million in milestones.

        The agreement also provides the Company with royalties on any sales of telaprevir in the Janssen territories, with a tiered royalty averaging in the mid-20% range, as a percentage of net sales in the Janssen territories, depending upon successful commercialization of telaprevir. Each of the parties will be responsible for drug supply in their respective territories. However, the agreement provides for the purchase by Janssen from the Company of materials required for Janssen's manufacture of the active pharmaceutical ingredient. In addition, Janssen will be responsible for certain third-party royalties on net sales in its territories. Janssen may terminate the agreement without cause at any time upon six months' notice to the Company.

        During the three and six months ended June 30, 2009, the Company recognized $12.8 million and $29.9 million, respectively, in revenues under the Janssen agreement, which included an amortized portion of the up-front payment and net reimbursements from Janssen for telaprevir development costs. During the three months ended June 30, 2008, the Company recognized $58.0 million in revenues under the Janssen agreement, which included an amortized portion of the up-front payment, a milestone of $45.0 million in connection with the commencement of a Phase 3 clinical trial of telaprevir, and net reimbursements from Janssen for telaprevir development costs. During the six months ended June 30, 2008, the Company recognized $83.5 million in revenues under the Janssen agreement, which included an amortized portion of the up-front payment, a milestone of $45.0 million in connection with the commencement of a Phase 3 clinical trial of telaprevir, a milestone of $10.0 million in connection with the commencement of the Phase 2 clinical trial of telaprevir in patients with genotype 2 and genotype 3 HCV infection and net reimbursements from Janssen for telaprevir development costs.

13. Guarantees

        As permitted under Massachusetts law, the Company's Articles of Organization and Bylaws provide that the Company will indemnify certain of its officers and directors for certain claims asserted against them in connection with their service as an officer or director. The maximum potential amount of future payments that the Company could be required to make under these indemnification provisions is unlimited. However, the Company has purchased directors' and officers' liability insurance policies that could reduce its monetary exposure and enable it to recover a portion of any future amounts paid. No indemnification claims are currently outstanding and the Company believes the estimated fair value of these indemnification arrangements is minimal.

        The Company customarily agrees in the ordinary course of its business to indemnification provisions in agreements with clinical trial investigators and sites in its drug development programs, in sponsored research agreements with academic and not-for-profit institutions, in various comparable agreements involving parties performing services for the Company in the ordinary course of business, and in its real estate leases. The Company also customarily agrees to certain indemnification provisions in its drug discovery, development and commercialization collaboration agreements. With respect to the

25

Notes to Condensed Consolidated Financial Statements (Continued)

(unaudited)

13. Guarantees (Continued)


Company's clinical trials and sponsored research agreements, these indemnification provisions typically apply to any claim asserted against the investigator or the investigator's institution relating to personal injury or property damage, violations of law or certain breaches of the Company's contractual obligations arising out of the research or clinical testing of the Company's compounds or drug candidates. With respect to lease agreements, the indemnification provisions typically apply to claims asserted against the landlord relating to personal injury or property damage caused by the Company, to violations of law by the Company or to certain breaches of the Company's contractual obligations. The indemnification provisions appearing in the Company's collaboration agreements are similar, but in addition provide some limited indemnification for its collaborator in the event of third-party claims alleging infringement of intellectual property rights. In each of the cases above, the indemnification obligation generally survives the termination of the agreement for some extended period, although the obligation typically has the most relevance during the contract term and for a short period of time thereafter. The maximum potential amount of future payments that the Company could be required to make under these provisions is generally unlimited. The Company has purchased insurance policies covering personal injury, property damage and general liability that reduce its exposure for indemnification and would enable it in many cases to recover a portion of any future amounts paid. The Company has never paid any material amounts to defend lawsuits or settle claims related to these indemnification provisions. Accordingly, the Company believes the estimated fair value of these indemnification arrangements is minimal.

        On February 12, 2008, the Company entered into underwriting agreements with Merrill Lynch, Pierce, Fenner & Smith Incorporated, on September 18, 2008, the Company entered into an underwriting agreement with Goldman, Sachs & Co. and on February 18, 2009, the Company entered into an underwriting agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated (collectively, the "Underwriting Agreements"), as the representative of the several underwriters, if any, named in such agreements, relating to the public offering and sale of shares of the Company's common stock or convertible senior subordinated notes. The Underwriting Agreement relating to each offering requires the Company to indemnify the underwriters against any loss they may suffer by reason of the Company's breach of representations and warranties relating to that public offering, the Company's failure to perform certain covenants in those agreements, the inclusion of any untrue statement of material fact in the prospectus used in connection with that offering, the omission of any material fact needed to make those materials not misleading, and any actions taken by the Company or its representatives in connection with the offering. The representations, warranties and covenants in the Underwriting Agreements are of a type customary in agreements of this sort. The Company believes the estimated fair value of these indemnification arrangements is minimal.

14. Contingencies

        The Company has certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a reserve for contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. There were no contingent liabilities accrued as of June 30, 2009 or December 31, 2008.

15. Management Transition

        Matthew W. Emmens, one of the Company's directors, became the Company's Chairman and Chief Executive Officer in May 2009. On February 5, 2009, the Company entered into a transition arrangement with Dr. Joshua S. Boger. The benefits under the transition arrangement include: (i) a lump sum payment of $2.9 million payable in November 2009, (ii) 18 months' accelerated vesting of his outstanding stock options, which will remain exercisable until December 31, 2010, subject to specified limitations, (iii) 18 months' accelerated vesting of each outstanding restricted stock award, treating each award as if it vests ratably over the term of the grant rather than the end of the service period and (iv) reimbursement for certain expenses. The Company recorded expenses of $1.4 million and $2.9 million, respectively, in the three and six months ended June 30, 2009 in connection with the lump sum payable in November 2009. In the three and six months ended June 30, 2009, the Company recorded a non-cash charge of $5.2 million and $10.5 million, respectively, due to the acceleration and extended exercisability of Dr. Boger's equity awards under the transition arrangement.

16. Recent Accounting Pronouncements

        In June 2009, the FASB issued SFAS No. 167, "Amendments to FASB Interpretation No. 46(R)" ("SFAS 167"). SFAS 167 requires a qualitative approach to identifying a controlling financial interest in a variable interest entity ("VIE"), and requires ongoing assessment of whether an entity is a VIE and whether an interest in a VIE makes the holder the primary beneficiary of the VIE. SFAS 167 is effective for the Company on January 1, 2010. The Company is evaluating the effect of the pending adoption of SFAS 167 on the Company's condensed consolidated financial statements.

        In June 2009, the FASB issued SFAS No. 166, "Accounting for Transfers of Financial Assets—an amendment of FASB Statement No. 140" ("SFAS 166"). SFAS 166 amends FASB Statement No. 140 to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor's continuing involvement in transferred financial assets. The recognition and measurement provisions of SFAS 166 shall be applied to transfers that occur on or after January 1, 2010, the effective date of SFAS 166 to the Company. The Company is evaluating the effect of the pending adoption of SFAS 166 on the Company's condensed consolidated financial statements.

        In April 2009, the FASB issued three FASB Staff Positions ("FSP"s) that are intended to provide additional application guidance and enhance disclosures about fair value measurements and impairments of securities. FSP No. FAS 157-4, "Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly," clarifies the objective and method of fair value measurement even when there has been a significant decrease in market activity for the asset being measured. FSP No. FAS 115-2 and FAS 124-2, "Recognition and Presentation of Other-Than-Temporary Impairments," establishes a new model for measuring other-than-temporary impairments for debt securities, including establishing criteria for when to recognize a write-down through earnings instead of other comprehensive income. FSP No. FAS 107-1 and APB 28-1, "Interim Disclosures about Fair Value of Financial Instruments," expands the fair value disclosures required for all financial instruments within the scope of FASB Statement No. 107, "Disclosures about Fair Value of Financial Instruments," to interim periods. All of these FSPs became effective for the Company on April 1, 2009. FSP No. FAS 157-4, FSP No.

FAS 115-2 and FAS 124-2, and FSP No. FAS 107-1 and APB 28-1 did not have an effect on the Company's condensed consolidated financial statements.

        In April 2009, the FASB issued FSP No. FAS 141(R)-1, "Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies," which amends SFAS 141(R) by establishing a model to account for certain pre-acquisition contingencies. In November 2008, the FASB ratified EITF Issue No. 08-7, "Accounting for Defensive Intangible Assets" ("EITF 08-7"). EITF 08-7 applies to defensive intangible assets, which are acquired intangible assets that the acquirer does not intend to actively use but intends to hold to prevent its competitors from obtaining access to them. FSP No. FAS 141(R)-1 and EITF 08-7 became effective on January 1, 2009. The implementation of FSP No. FAS 141(R)-1 and EITF 08-7 did not have an effect on the Company's condensed consolidated financial statements.

17. Subsequent Event

        On July 30, 2009, the Company amended its license, development and commercialization agreement with Mitsubishi Tanabe Pharma Corporation ("Mitsubishi Tanabe"). Under the amended agreement, the Company will receive $105.0 million following signing the amendment, and will be eligible to receive further contingent milestone payments in lieu of royalties, which if realized would range between $15.0 million and $65.0 million. The amended agreement provides to Mitsubishi Tanabe a fully-paid license to commercialize telaprevir as part of a combination regimen with interferon and ribavirin to treat HCV infection in Japan and other countries in the Far East, as well as rights to manufacture telaprevir for sale in Japan and the Far East.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

        We are in the business of discovering, developing and commercializing small molecule drugs for the treatment of serious diseases. Telaprevir, our lead drug candidate, is an oral hepatitis C protease inhibitor and one of the most advanced of a new class of antiviral treatments in clinical development that targets hepatitis C virus, or HCV, infection. Telaprevir is being evaluated in a fully-enrolled registration program focused on treatment-naïve and treatment-failure patients with genotype 1 HCV. We currently intend to submit a new drug application, or NDA, for telaprevir in the United States in the second half of 2010, assuming the successful completion of the registration program. We also are developing, among other compounds, VX-770 and VX-809, drug candidates for the treatment of patients with cystic fibrosis, or CF. In the second quarter of 2009, we began a registration program for VX-770 that focuses on CF patients with the G551D mutation in the gene responsible for CF. We intend to continue investing in our research programs with the goal of adding to our pipeline drug candidates designed to address significant unmet medical needs and provide substantial benefits to patients.

Business Focus

        Over the next several years, we expect to focus a substantial portion of our resources on the development and commercialization of telaprevir. Our clinical development program is designed to support registration by us of telaprevir in North America for treatment-naïve and treatment-failure patients with genotype 1 HCV, and by our collaborators, Janssen Pharmaceutica, N.V., a Johnson & Johnson company, and Mitsubishi Tanabe Pharma Corp., in international markets.

        In the second quarter of 2009, we initiated a registration program for VX-770 focused on patients with CF who have the G551D mutation. We also expect to continue the development of VX-809, an investigational CFTR corrector compound that is being evaluated in a Phase 2a clinical trial in patients with CF. As a result, we expect that over the next several years we will need to substantially increase resources focused on the development of our CF drug candidates. We plan to leverage the infrastructure that we are building in preparation for the launch of telaprevir to support the potential launch of VX-770.

        In addition to the registration programs for telaprevir and VX-770, we plan to continue investing in our research and early development programs and to develop selected drug candidates that emerge from those programs, alone or with third-party collaborators. Using our drug discovery capability, which integrates biology, pharmacology, biophysics, chemistry, automation and information technologies in a coordinated manner, we have identified, among other drug candidates: telaprevir; VX-813 and VX-985, two additional HCV protease inhibitors; VX-770 and VX-809; and VX-509 and VX-467, novel Janus Kinase 3, or JAK3, inhibitors that target immune-mediated inflammatory diseases.

        Our acquisition of ViroChem Pharma Inc., or ViroChem, in March 2009 for $100.0 million in cash plus 10.7 million shares of our common stock, represents a significant investment in order to acquire drug candidates that are in Phase 1 clinical development and could potentially be used to treat HCV infection in combination with telaprevir. In order to realize benefits from this acquisition, we will need to invest significant resources in the development of these potential combination therapies.

Drug Discovery and Clinical Development

        Discovery and development of a new pharmaceutical product is a lengthy and resource-intensive process, which may take 10 to 15 years or more. Throughout this entire process, potential drug candidates are subjected to rigorous evaluation, driven in part by stringent regulatory considerations, designed to generate information concerning efficacy, side-effects, proper dosage levels and a variety of

29


Table of Contents


other physical and chemical characteristics that are important in determining whether a drug candidate should be approved for marketing as a pharmaceutical product. The toxicity characteristics and profile of drug candidates at varying dose levels administered for varying periods of time also are monitored and evaluated during the nonclinical and clinical development process. Most chemical compounds that are investigated as potential drug candidates never progress into formal development, and most drug candidates that do advance into formal development never become commercial products. A drug candidate's failure to progress or advance may be the result of any one or more of a wide range of adverse experimental outcomes including, for example, the lack of sufficient efficacy against the disease target, the lack of acceptable absorption characteristics or other physical properties, difficulties in developing a cost-effective manufacturing or formulation method, or the discovery of toxicities or side-effects that are unacceptable for the disease indication being treated or that adversely affect the competitive commercial profile of the drug candidate.

        Designing and coordinating large-scale clinical trials to determine the efficacy and safety of drug candidates and to support the submission of an NDA requires significant financial resources, along with extensive technical and regulatory expertise and infrastructure. Prior to commencing a late-stage clinical trial of any drug candidate, we must work collaboratively with regulatory authorities, including the United States Food and Drug Administration, or FDA, in order to identify the specific scientific issues that need to be addressed by the clinical trials in order to support continued development and approval of the drug candidate. These discussions with regulatory authorities typically occur over a period of months and can result in significant changes to planned clinical trial designs or timelines. In addition, even after agreement with respect to a clinical trial design has been reached, regulatory authorities may request additional clinical trials or changes to existing clinical trial protocols. If the data from our ongoing clinical trials or nonclinical studies regarding the safety or efficacy of our drug candidates are not favorable, we may be forced to delay or terminate the clinical development program, which, particularly in the case of telaprevir, would materially harm our business. Further, even if we obtain marketing approvals from the FDA and comparable foreign regulatory authorities in a timely manner, we cannot be sure that the drug will be commercially successful.

        Our investments are subject to the considerable risk that one or more of our drug candidates will not progress to product registration due to a wide range of adverse experimental outcomes. We monitor the results of our clinical trials, discovery research and our nonclinical studies and frequently evaluate our portfolio investments in light of new data and scientific, business and commercial insights with the objective of balancing risk and potential. This process can result in relatively abrupt changes in focus and priority as new information becomes available and is analyzed and we gain additional insights into ongoing programs and potential new programs. Although we believe that our development activities and the clinical trial data we have obtained to date have reduced the risks associated with obtaining marketing approval for telaprevir, we cannot be sure that our development of telaprevir will lead successfully to regulatory approval of telaprevir on a timely basis, or at all, or that obtaining regulatory approval will lead to commercial success of telaprevir. With respect to our other drug candidates, we have more limited data from clinical trials and nonclinical studies and as a result it is difficult to predict which, if any, of these drug candidates will result in pharmaceuticals products.

Drug Candidates

    HCV

    Telaprevir

        Telaprevir, our oral HCV protease inhibitor, is being investigated in a registration program focused on patients with genotype 1 HCV that includes ADVANCE and ILLUMINATE, which are Phase 3 clinical trials in treatment-naïve patients, and REALIZE, which is a Phase 3 clinical trial in treatment-failure patients. Enrollment in ADVANCE, ILLUMINATE and REALIZE was completed in October

30


Table of Contents

2008, January 2009 and February 2009, respectively. Telaprevir dosing is complete in all three of these Phase 3 clinical trials. We expect to have sustained viral response, or SVR, data from the ADVANCE and ILLUMINATE clinical trials in the first half of 2010 and SVR data from the REALIZE clinical trial in mid-2010. We currently intend to submit an NDA for telaprevir in the second half of 2010, assuming the successful completion of our ongoing registration program. In addition to the clinical trials in our registration program, our collaborators and we are conducting several additional clinical trials, including trials evaluating twice-daily dosing of telaprevir and the use of telaprevir for treatment of patients with other HCV genotypes. We expect to present SVR data from the clinical trial evaluating twice-daily dosing of telaprevir at the Annual Meeting of the American Association for the Study of Liver Diseases that begins in October 2009.

        We have completed three Phase 2b clinical trials of telaprevir-based combination therapy in patients with genotype 1 HCV, which enrolled an aggregate of approximately 580 treatment-naïve patients and 440 patients who did not achieve an SVR with a previous treatment with pegylated-interferon, or peg-IFN, and ribavirin, or RBV. The SVR rates on an intent-to-treat basis of the patients in the 24-week telaprevir-based treatment arms and the control arms of PROVE 1 and PROVE 2, the two Phase 2b clinical trials that evaluated treatment-naïve patients, are set forth in the table below:

 
  PROVE 1   PROVE 2  
24-week telaprevir-based treatment arm:              
  telaprevir in combination with peg-IFN and RBV for 12 weeks, followed by peg-IFN and RBV alone for 12 weeks     61 %   69 %
48-week control arm:              
  48 weeks of therapy with peg-IFN and RBV     41 %   46 %

        The SVR rates of the patients on an intent-to-treat basis in the 24-week telaprevir-based triple-therapy treatment arm, the 48-week telaprevir-based treatment arm and the control arm of PROVE 3, the Phase 2b clinical trial that evaluated treatment-failure patients, are set forth in the table below:

 
  Non-responders   Relapsers   Breakthroughs   Total  
24-week telaprevir-based triple-therapy treatment arm:                          
  telaprevir in combination with peg-IFN and RBV for 12 weeks, followed by peg-IFN and RBV alone for 12 weeks     39% (n=66)     69% (n=42)     57% (n=7)     51% (n=115)  
48-week telaprevir-based treatment arm:                          
  telaprevir in combination with peg-IFN and RBV for 24 weeks, followed by peg-IFN and RBV alone for 24 weeks     38% (n=64)     76% (n=41)     50% (n=8)     52% (n=113)  
48-week control arm:                          
  48 weeks of therapy with peg-IFN and RBV     9% (n=68)     20% (n=41)     40% (n=5)     14% (n=114)  

        The adverse event profile of telaprevir generally has been consistent across our Phase 2 clinical trials, which have principally involved clinical trial sites in North America and Europe. Safety data from our Phase 2 clinical trials indicated that the most common adverse events, regardless of treatment assignment, were fatigue, rash, headache and nausea. The most common adverse events reported more frequently in patients receiving telaprevir than in the control arms were gastrointestinal events, skin events—rash and pruritus—and anemia. There have been reports of severe rashes in clinical trials involving telaprevir-based treatments, including several reports from the clinical trials being conducted by Mitsubishi Tanabe in Japan, where telaprevir has advanced into Phase 3 clinical trials in combination with peg-IFN and RBV. Rash resulted in treatment discontinuations in the telaprevir-based treatment arms in approximately 7% of patients in PROVE 1 and PROVE 2 and 5% of patients in PROVE 3.

Other adverse events reported in our Phase 2 clinical trials generally were similar in type and frequency to those seen with peg-IFN and RBV treatment.

        The successful development and commercialization of telaprevir is critical to the success of our business as currently conducted. While we are devoting significant resources, time and attention to the development, potential regulatory approval and a successful commercial launch of telaprevir, all of these efforts involve significant scientific and execution risks and can be adversely affected by events, such as competitive activities, adverse trial results and regulatory actions, outside of our direct control.

    HCV Polymerase Inhibitors

        HCV polymerase inhibitors, including our HCV polymerase inhibitors VX-222 (formerly VCH-222) and VX-759 (formerly VCH-759), are direct-acting antivirals that inhibit the ability of the hepatitis C virus to replicate through a mechanism that is distinct from HCV protease inhibitors such as telaprevir. VX-222 and VX-759 were evaluated by ViroChem in Phase 1 clinical trials. In a Phase 1 viral kinetic clinical trial involving five treatment-naïve patients with genotype 1 HCV infection, VX-222 dosed at 750 mg twice daily resulted in a median 3.7 log10 decrease in HCV RNA—equivalent to a 5,000-fold reduction in virus in the blood—at the end of three days of dosing. The results were consistent from patient to patient, and across HCV genotype 1 subtypes. In clinical evaluations of VX-222 to date, no serious adverse events have been observed. VX-222 has completed 28-day non-clinical toxicology studies in two species.

        In the second quarter of 2009, we initiated a multi-dose viral kinetic clinical trial to evaluate the antiviral activity, safety, tolerability and pharmacokinetics of VX-222 in patients with genotype 1 HCV infection. There currently are no ongoing clinical trials of VX-759. The ongoing clinical trial of VX-222 will evaluate the antiviral activity of VX-222 dosed as monotherapy for three days in approximately 32 treatment-naïve patients. We expect to complete this clinical trial in the third quarter of 2009. We anticipate initiating a drug-drug interaction clinical trial of VX-222 and telaprevir in healthy volunteers in the third quarter of 2009. We plan to begin a combination clinical trial of telaprevir with VX-222 in patients with genotype 1 HCV as early as the fourth quarter of 2009 and expect to have data from this clinical trial in the first half of 2010.

    Cystic Fibrosis

    VX-770

        In May 2009, we initiated a registration program, referred to as ENDEAVOR, for VX-770, which is an investigational cystic fibrosis transmembrane conductance regulator, or CFTR, potentiator that targets the defective CFTR protein that causes CF. The VX-770 registration program will focus on patients with the G551D mutation, which is present in approximately 4% of the CF population in the United States. ENDEAVOR will consist of three clinical trials.

        The primary clinical trial, which is referred to as STRIVE, is a Phase 3 clinical trial of VX-770 in patients 12 years and older with the G551D mutation on at least one of the patient's two CFTR genes, or alleles. This randomized, placebo-controlled, double-blind, parallel-group clinical trial is designed to enroll a minimum of 80 patients who will receive either VX-770 or placebo for 48 weeks. In the trial, VX-770 will be dosed as a single 150 mg tablet twice daily. The primary endpoint for the STRIVE clinical trial is absolute change from baseline in percent predicted forced expiratory volume in one second, or FEV1, the lung function test most commonly used to monitor CF disease progression, through week 24. Additional FEV1 measurements will be taken through 48 weeks as a secondary endpoint. Additional secondary endpoints, including sweat chloride, will be measured to evaluate the effect of VX-770 on improving the function of the defective CFTR protein. The STRIVE clinical trial is currently open to patient enrollment, and we expect STRIVE to be fully enrolled in the first quarter of 2010.

Table of Contents

        The second clinical trial, which is referred to as ENVISION, is a Phase 3 clinical trial of VX-770 in patients between 6 to 11 years of age with the G551D mutation on at least one allele. ENVISION is a two-part, randomized, placebo-controlled, double-blind, parallel-group clinical trial of VX-770. Part 1 of ENVISION will be a single-dose pharmacokinetic clinical trial that is expected to enroll approximately 10 patients. Following an analysis of data from Part 1, Part 2 of the ENVISION trial is expected to enroll approximately 30 patients who will receive either VX-770 or placebo for 48 weeks. The primary endpoint of the trial is absolute change from baseline in percent predicted FEV1 through week 24. Secondary endpoints, including sweat chloride, will be measured to evaluate the effect of VX-770 on improving the function of the defective CFTR protein. Part 1 of the ENVISION clinical trial is opened to patient enrollment.

        The third clinical trial, which is referred to as DISCOVER, will be a Phase 2 exploratory clinical trial of VX-770 in patients with CF who are 12 years and older and homozygous for the F508del mutation. This randomized, placebo-controlled, double-blind, parallel-group clinical trial is expected to enroll approximately 120 patients who will receive either VX-770 or placebo for 16 weeks. In DISCOVER, VX-770 will be dosed as a single 150 mg tablet twice daily. The primary endpoints of the DISCOVER clinical trial are safety as well as absolute change from baseline in percent predicted FEV1 through week 16. Additional secondary endpoints, including sweat chloride, will be measured to evaluate the effect of VX-770 on improving the function of the defective CFTR protein. We expect to initiate the DISCOVER clinical trial in the third quarter of 2009.

        In October 2008, we completed a Phase 2a clinical trial of VX-770 in 39 patients with CF with the G551D mutation. Patients in the Phase 2a clinical trial received VX-770 over 14-day and 28-day dosing periods. The primary endpoint for this clinical trial was safety, and no serious adverse events attributable to VX-770 were observed. The promising lung function data from this Phase 2a clinical trial, as measured by improvements in FEV1, and the observed changes in biomarkers that seek to measure the activity of the CFTR protein, were used to design the ENDEAVOR registration program.

    VX-809

        We have conducted Phase 1 clinical trials of VX-809 in healthy volunteers and an escalating single-dose pharmacokinetics and safety clinical trial of VX-809 in patients with CF who carry the F508del mutation on at least one allele. In the first quarter of 2009, we initiated a Phase 2a clinical trial primarily designed to evaluate the safety and tolerability of multiple doses of VX-809 in patients with CF. In addition to assessing safety, the trial will evaluate the effect of VX-809 on measures of CFTR function and whether VX-809 has an effect on FEV1. The trial is expected to enroll approximately 90 patients homozygous for the F508del mutation in the CFTR gene, the most common mutation in CF patients. We expect to complete this clinical trial in early 2010.

    Immune-mediated Inflammatory Disease

        VX-509 is a novel oral JAK3 inhibitor that we believe has the potential to be used in multiple immune-mediated inflammatory disease, or IMID, indications. We have completed the Phase 1 clinical trials of VX-509, including a Phase 1 single and multiple, 14-day, dose-ranging clinical trial of VX-509 in healthy volunteers. The safety data from the 14-day dose-ranging clinical trial of VX-509 supported further development. In addition, VX-509 showed a dose-dependent and reversible reduction in PSTAT-5, a specific biomarker of JAK3 activity, and a high degree of selectivity for JAK3 over JAK2. These data were consistent with data from in vitro studies that indicated that VX-509 was highly selective for JAK3 compared to certain other JAK and non-JAK kinases in cell-based assays. We may seek to license VX-509 and/or VX-467 to a corporate collaborator in order to fund and support other research and development investments.

Corporate Collaborations

        Corporate collaborations have been and will continue to be an important component of our business strategy. Under our agreement with Janssen, we have retained exclusive commercial rights to telaprevir in North America, and we are leading the global clinical development program. Janssen agreed to be responsible for 50% of the drug development costs under the development program for telaprevir in North America and the Janssen territories, to pay us contingent milestone payments based on successful development, approval and launch of telaprevir, to be responsible for the commercialization of telaprevir outside of North America and the Far East and to pay us royalties on any sales of telaprevir in its territories. The principal remaining milestones under our agreement with Janssen relate to marketing authorization for telaprevir from the European Medicines Evaluation Agency and the launch of telaprevir in the European Union. These milestones include $100.0 million related to regulatory submission and approval and $150.0 million related to launch of telaprevir. We anticipate, based on projected development and commercial timelines for telaprevir, and assuming successful development, that these milestones will be earned prior to April 2012. In July 2009, we announced our intention to explore the sale of our rights to these milestone payments.

        We also have a collaboration with Mitsubishi Tanabe with respect to the development of telaprevir in Japan and other countries in the Far East. Mitsubishi Tanabe is conducting Phase 3 registration trials in Japan of telaprevir in combination with peg-IFN and RBV, in approximately 300 patients with genotype 1 HCV. This registration program is expected to be fully enrolled in the third quarter of 2009, and SVR data from these clinical trials is expected to be available in 2010. On July 30, 2009, we amended our license, development and commercialization agreement with Mitsubishi Tanabe. Under the amended agreement, we expect to receive $105.0 million in the third quarter of 2009, and will be eligible to receive further contingent milestone payments in lieu of royalties, which if realized would range between $15.0 million and $65.0 million. The amended agreement provides to Mitsubishi Tanabe a fully-paid license to commercialize telaprevir as part of a combination regimen with peg-IFN and RBV to treat HCV in Japan and the Far East, as well as rights to manufacture telaprevir for sale in Japan and the Far East.

        Our drug candidate pipeline also includes Aurora kinase inhibitors that are being investigated by Merck & Co., Inc. for oncology indications. In the second quarter of 2008, Merck initiated a Phase 1 clinical trial of MK-5108 (VX-689) alone and in combination with docetaxel in patients with advanced and/or refractory tumors. In the third quarter of 2008, Merck selected additional Aurora kinase inhibitors for potential development.

        We will not have the resources for some time to develop and commercialize all drug candidates for which we have rights, and therefore we will need to rely on corporate collaborations for the development and commercialization of some or all of our new drug candidates. Historically, we have been successful in initiating and concluding productive collaborations, but we will need to continue to do so in the future, even though economic and competitive conditions may be different than in the past.

Acquisition of ViroChem Pharma Inc.

        In March 2009, we acquired ViroChem, a privately-held Canadian biotechnology company, for $100.0 million in cash plus 10.7 million shares of our common stock. ViroChem was in the business of discovering and developing drug candidates for the treatment of HCV and HIV infection, including VX-222 and VX-759, which were two HCV polymerase inhibitors and ViroChem's two lead drug candidates. We are planning on pursuing potential combination therapies for the treatment of HCV infection.

        After acquiring ViroChem, we restructured its operations in order to focus ViroChem's research and development activities on drug candidates for the treatment of HCV infection. ViroChem currently

34


Table of Contents


has approximately 35 employees and leases a research facility in Laval, Canada. The expenses associated with continuing the research and development activities at our new research site in Canada are not expected to be significant in comparison to the costs and expenses related to our other ongoing research and development activities. We currently are evaluating ViroChem's non-HCV programs and may seek to license rights to ViroChem's other assets to a third-party collaborator.

Financing Strategy

        At June 30, 2009, we had $754.4 million of cash, cash equivalents and marketable securities, which was a decrease of $77.7 million from $832.1 million at December 31, 2008. This decrease was a result of cash used to fund our operations during the first half of 2009 and the $100.0 million of cash used in our acquisition of ViroChem in March 2009 partially offset by net proceeds of $313.3 million from the sale in February 2009 of 10.0 million shares of our common stock.

        We have incurred losses from our inception and expect to continue to incur losses at least until we obtain approval for and successfully commercialize a product, if we ever do. Therefore, we are dependent in large part on our continued ability to raise significant funding to finance our research and development operations, to create a commercial infrastructure, and to meet our overhead costs and long-term contractual commitments and obligations. To date, we have secured funds principally through capital market transactions, strategic collaborative agreements, proceeds from the disposition of assets, investment income and the issuance of common stock under our employee benefit plans.

        We expect that we will need additional capital in order to complete the development and commercialization of telaprevir while at the same time continuing the development of our other drug candidates, including VX-770. We may raise additional capital from public offerings or private placements of our securities or other methods of financing. We cannot be sure that any such financing opportunities will be available on acceptable terms, if at all. If adequate funds are not available on acceptable terms, or at all, we may be required to curtail significantly or discontinue one or more of our research, drug discovery or development programs, including clinical trials, incur significant cash exit costs, or attempt to obtain funds through arrangements with collaborators or others that may require that we relinquish rights to certain of our technologies or drug candidates.

        As part of our strategy for managing our capital structure, we have from time to time adjusted the amount and maturity of our debt obligations through new issues, privately negotiated transactions and market purchases, depending on market conditions and our perceived needs at the time. For example, in the second quarter of 2009, we exchanged 6.6 million shares of newly-issued common stock for $143.5 million in aggregate principal amount of our 4.75% convertible senior subordinated notes due 2013, or 2013 Notes, plus accrued interest. We expect to continue pursuing a general financial strategy that may lead us to undertake one or more additional transactions with respect to our outstanding debt obligations, and the amounts involved in any such transactions, individually or in the aggregate, may be material. Any such transactions may or may not be similar to transactions in which we have engaged in the past.

Critical Accounting Policies and Estimates

        Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States. The preparation of these financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. These items are monitored and analyzed by management for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are reflected in reported results for

35


Table of Contents


the period in which they become known. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates if past experience or other assumptions do not turn out to be substantially accurate. There were no material changes during the six months ended June 30, 2009 to our critical accounting policies as reported in our Annual Report on Form 10-K for the year ended December 31, 2008. We have added a critical accounting policy regarding business combinations as a result of our acquisition of ViroChem in March 2009 and have supplemented our critical accounting policy regarding up-front license fees.

Business Combinations

        In March 2009, we acquired ViroChem for $100.0 million in cash and common stock with a fair market value of $290.6 million. Under Financial Accounting Standards Board ("FASB") Statement No. 141 (Revised 2007), "Business Combinations" ("SFAS 141(R)"), which became effective on January 1, 2009, we assign the value of the consideration transferred to acquire a business to the tangible assets and identifiable intangible assets acquired and liabilities assumed on the basis of their fair values at the date of acquisition. For purposes of the condensed consolidated balance sheet, we allocated the purchase price for ViroChem to the net tangible assets and intangible assets. The difference between the purchase price and the fair value of assets acquired and liabilities assumed was allocated to goodwill. This goodwill relates to the potential synergies from the possible development of combination therapies involving telaprevir and the acquired drug candidates. The allocations recorded on our condensed consolidated balance sheet included $525.9 million of intangible assets related to in-process research and development and a $162.5 million deferred tax liability.

        The intangible assets are in-process research and development assets relating to the drug candidates being developed by ViroChem, primarily VX-222 and VX-759, each of which was in Phase 1 clinical development at the date of acquisition. VX-222 and VX-759 had estimated fair values of $412.9 million and $105.8 million, respectively. In addition, we considered ViroChem's other clinical drug candidates and determined that VCH-286, ViroChem's lead HIV drug candidate, had an estimated fair value of $7.2 million, based on development costs through the acquisition date, and that the other clinical drug candidates had no fair value because the clinical and non-clinical data for those drug candidates did not support further development as of the acquisition date. We also considered ViroChem's preclinical programs and other technologies and determined that because of uncertainties related to the safety, efficacy and commercial viability of the potential drug candidates, market participants would not ascribe value to these assets.

        We assess the fair value of assets, including intangible assets such as in-process research and development, using a variety of methods including present-value models that are based upon multiple probability-weighted scenarios involving the development and potential commercialization of the acquired drug candidates. The present-value models used to estimate the fair values of VX-222 and VX-759 reflect significant assumptions regarding the estimates a market participant would make in order to evaluate a drug development asset, including the probability of completing in-process research and development projects, which requires successfully completing clinical trials and obtaining regulatory approval for marketing of the associated drug candidate; estimates regarding the timing of and the expected costs to complete in-process research and development projects; estimates of future cash flows from potential product sales; and appropriate discount rates. The fair value of VX-222 and VX-759 was based on the estimated fair value that would be ascribed to each of these compounds by a market participant that acquired both compounds in a single transaction. The probability of advancing VX-222 and VX-759 through various phases of development reflects the understanding among market participants that most drug candidates that enter Phase 2 clinical trials are not ultimately approved. While on the date of acquisition each of the HCV polymerase inhibitors was at a similar stage of development, we attributed a significantly higher value to VX-222 than to VX-759 because the clinical

36


Table of Contents


and non-clinical data regarding VX-222 was significantly more promising than the clinical and non-clinical data regarding VX-759. In addition, we determined that a market participant would not be likely to continue development of VX-759 unless future data from clinical trials or non-clinical studies of VX-222 resulted in a delay or discontinuation of the VX-222 development program. Finally, while the duration and cost of non-clinical studies and clinical trials may vary significantly over the life of a project and are difficult to predict, a market participant would assume that it would take several years to complete each phase of clinical trials for a drug candidate for the treatment of patients with HCV and that future cash flows, if any, would not be generated until a drug candidate had completed all required phases of clinical trials and had obtained regulatory approval. The risk-adjusted discount rate for each of these projects is approximately 28%.

        Initially, the in-process research and development assets are recorded at fair value and accounted for as indefinite-lived intangible assets in accordance with FASB Statement No. 142, "Goodwill and Other Intangible Assets," as amended by SFAS 141(R). These assets will be maintained on our condensed consolidated balance sheets until either the research and development project underlying them is completed or the assets become impaired. If a project is completed, the carrying value of the related intangible asset would be amortized over the remaining estimated life of the asset. If a project becomes impaired or is abandoned, the carrying value of the related intangible asset would be written down to its fair value and an impairment charge would be taken in the period in which the impairment occurs. In order to complete an acquired research and development project, the related drug candidate will need to be evaluated in later-stage clinical trials, which are subject to all of the risks and uncertainties associated with the development of pharmaceutical products. If the fair value of any of these drug candidates, and in particular VX-222, becomes impaired as the result of unfavorable safety or efficacy data from any ongoing or future clinical trial or because of any other information regarding the prospects of successfully developing or commercializing the drug candidate, we could incur significant charges in the period in which the impairment occurs. These intangible assets will be tested for impairment on an annual basis during the fourth quarter, or earlier if impairment indicators are present. Post-acquisition research and development expenses related to the in-process research and development projects will be expensed as incurred.

Up-front License Fees

        We recognize revenues from nonrefundable, up-front license fees related to collaboration agreements, including the $165.0 million we received from Janssen in 2006, on a straight-line basis over the contracted or estimated period of performance. The period of performance over which the revenues are recognized is typically the period over which the research and/or development is expected to occur. As a result, we often are required to make estimates regarding drug development and commercialization timelines for compounds being developed pursuant to a collaboration agreement. Because the drug development process is lengthy and our collaboration agreements typically cover activities over several years, this approach often has resulted in the deferral of significant amounts of revenue into future periods. In addition, we periodically evaluate our estimates in light of changes and anticipated changes in the development plans for our drug candidates and because of the many risks and uncertainties associated with the development of drug candidates, our estimates regarding the period of performance have changed in the past and may change in the future. Our estimates regarding the period of performance under the Janssen collaboration agreement were adjusted in 2007 as a result of changes in the global development plan for telaprevir. This adjustment was made on a prospective basis beginning in the period in which the change was identified and resulted in a decrease in the amount of revenues we were recognizing from the Janssen collaboration by $2.6 million per fiscal quarter after the adjustment. Any future adjustment in our estimates of the period of performance under our collaborations could result in substantial changes to the period over which the revenues from an up-front license fee related to each such collaboration are recognized. If we adjusted our estimates as of July 1, 2009 to increase the period of performance under the Janssen agreement by one year, it

would result in a decrease in the amount of deferred revenues we recognize from our Janssen collaboration of approximately $1.1 million per fiscal quarter beginning in the third quarter of 2009.

Net Loss

        In the second quarter of 2009 as compared to the second quarter of 2008, our net loss increased by $80.0 million, or 88%. In the first half of 2009 as compared to the first half of 2008, our net loss increased by $146.5 million, or 78%. The increases in net loss in the second quarter and first half of 2009 as compared to the comparable periods in 2008 were the result of significant increases in costs and expenses combined with significant decreases in our revenues. Our lower revenues were primarily the result of a $45.0 million milestone payment that we recognized in the second quarter of 2008 and a $10.0 million milestone payment that we recognized in the first quarter of 2008 for which there were no corresponding milestone payments in the first half of 2009. The increased expenses included increased operating expenses related to the increased size of our workforce and to our late-stage clinical programs and increased stock-based compensation expense and restructuring expense. In addition, in the second quarter of 2009, we had a $12.3 million non-cash expense on the exchange of a portion of the 2013 Notes into our common stock and in the first half of 2009 we had $7.8 million of acquisition-related expenses from our acquisition of ViroChem and additional expenses related to our CEO transition.

Net Loss per Share

        Our net loss for the three months ended June 30, 2009 was $0.99 per basic and diluted common share compared to $0.66 per basic and diluted common share for the three months ended June 30, 2008. Our net loss for the six months ended June 30, 2009 was $2.03 per basic and diluted common share compared to $1.37 per basic and diluted common share for the six months ended June 30, 2008. The increases in net loss per common share in the three and six months ended June 30, 2009 compared to the comparable periods in 2008 were the result of the increased net losses for the periods in 2009 partially offset by increases in the basic and diluted weighted-average number of common shares outstanding in 2009. The increases in the weighted-average number of common shares outstanding in 2009 were primarily the result of the equity offerings in February 2008, September 2008 and February 2009 and our acquisition of ViroChem in March 2009. Our basic and diluted weighted-average number of common shares outstanding increased from 138.7 million in the three months ended June 30, 2008 to 172.6 million in the three months ended June 30, 2009 and from 136.6 million in the six months ended June 30, 2008 to 164.3 million in the six months ended June 30, 2009.

    net reimbursements from Janssen for development costs of telaprevir; and

39


Table of Contents

    an amortized portion of the $165.0 million up-front payment.

        The $45.2 million, or 78%, decrease in our revenues from Janssen in the second quarter of 2009 compared to the second quarter of 2008 and the $53.6 million, or 64%, decrease in our revenues from Janssen in the six months ended June 30, 2009 compared to the six months ended June 30, 2008 were primarily the result of a decrease in milestone payments from our Janssen collaboration. We recognized a $45.0 million milestone payment in the second quarter of 2008 and a total of $55.0 million in milestone payments in the first half of 2008 for which there were no corresponding milestone payments in 2009. During the second half of 2009, we expect to continue to recognize revenue from net reimbursements from Janssen for telaprevir development costs and an amortized portion of the $165.0 million up-front payment. The principal remaining milestones under our agreement with Janssen relate to marketing authorization for telaprevir from the European Medicines Evaluation Agency and the launch of telaprevir in the European Union. These milestones include $100.0 million related to regulatory filing and approval and $150.0 million related to launch of telaprevir. We have announced our intention to explore the sale of our rights to these milestones, which we anticipate, based on projected development and commercial timelines for telaprevir, and assuming successful development, will be earned prior to April 2012.

        Our revenues from our other collaborative arrangements decreased in the three months ended June 30, 2009 compared to the three months ended June 30, 2008 and decreased significantly in the six months ended June 30, 2009 compared to the six months ended June 30, 2008. On July 30, 2009, we entered into an amendment to our license, development and commercialization agreement with Mitsubishi Tanabe that provides for a $105.0 million payment in connection with the execution of the amendment. We expect that we will begin recognizing revenues related to this payment commencing in the third quarter of 2009, and that as a result our total collaborative and other research and development revenues will increase in the second half of 2009 as compared to the first half of 2009.

    Royalty Revenues

        Our royalty revenues relate to sales of the HIV protease inhibitors Lexiva/Telzir and Agenerase by GlaxoSmithKline. Until May 30, 2008, these royalty revenues were based on actual and estimated worldwide net sales of Lexiva/Telzir and Agenerase. On May 30, 2008, we sold our right to receive future royalties from GlaxoSmithKline with respect to these HIV protease inhibitors, excluding the portion allocated to pay a subroyalty on these net sales to a third party, in return for a one-time cash payment of $160.0 million. We deferred the recognition of $155.1 million of revenues from this sale. We are recognizing these deferred revenues over the term of our agreement with GlaxoSmithKline under the units-of-revenue method. We will also continue to recognize royalty revenues equal to the amount of the third-party subroyalty and an offsetting royalty expense for the third-party subroyalty payment.

        The $3.8 million, or 39%, decrease in royalty revenues in the three months ended June 30, 2009 compared to three months ended June 30, 2008 and the $8.5 million, or 41%, decrease in royalty revenues in the six months ended June 30, 2009 compared to six months ended June 30, 2008 resulted primarily from this sale of our future HIV royalties in the second quarter of 2008. In 2009, we expect that we will recognize as royalty revenues a portion of the remaining deferred revenues from the sale of our HIV royalty stream plus the full amount of the third-party subroyalty.

        The $9.8 million and $37.1 million increases in our total research and development expenses in the three and six months ended June 30, 2009, respectively, compared to the same periods in 2008 were primarily the result of increases in expenses related to our workforce.

        Our research and development expenses include internal and external costs incurred for our drug candidates, including telaprevir and VX-770. We do not assign to individual drug candidates our internal costs such as salary and benefits, stock-based compensation expense, laboratory supplies and infrastructure costs because the employees within our research and development groups are typically deployed across multiple research and development programs. These internal costs are significantly greater than our external costs, such as the costs of services provided to us by clinical research organizations and other outsourced research, which we do allocate by individual drug program. All research and development costs for our drug candidates are expensed as incurred.

        To date, we have incurred in excess of $3.1 billion in research and development expenses associated with drug discovery and development. The successful development of our drug candidates is highly uncertain and subject to a number of risks. In addition, the duration of clinical trials may vary substantially according to the type, complexity and novelty of the drug candidate. The FDA and comparable agencies in foreign countries impose substantial requirements on the introduction of therapeutic pharmaceutical products, typically requiring lengthy and detailed laboratory and clinical testing procedures, sampling activities and other costly and time-consuming procedures. Data obtained from nonclinical and clinical activities at any step in the testing process may be adverse and lead to discontinuation or redirection of development activity. Data obtained from these activities also are

41


Table of Contents


susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The duration and cost of discovery, nonclinical studies and clinical trials may vary significantly over the life of a project and are difficult to predict. Therefore, accurate and meaningful estimates of the ultimate costs to bring our drug candidates to market are not available.

        Our lead drug candidate telaprevir represents the largest portion of our development costs for our clinical drug candidates. Based on the completion of enrollment of our Phase 3 clinical trials of telaprevir in February 2009, we anticipate that our ongoing Phase 3 clinical trials will be completed in mid 2010, but that development costs associated with other clinical trials of telaprevir may continue after the completion of the registration trials. If we are able to successfully commercialize telaprevir in accordance with current development timelines, we anticipate revenues and cash flows from the sales of telaprevir to commence in 2011. Our other drug candidates are less advanced and as a result any estimates regarding development timelines for these drug candidates are highly subjective and subject to change, and we cannot at this time make a meaningful estimate when, if ever, these drug candidates, including the drug candidates we acquired from ViroChem, will generate revenues and cash flows.

        The $2.9 million and $4.9 million increases in total research expenses in the three and six months ended June 30, 2009, respectively, compared to the same periods in 2008, were primarily the result of increased expenses related to our workforce partially offset by decreased contractual services and infrastructure costs.

        Our development expenses increased in the three and six months ended June 30, 2009 compared to the same periods in 2008 primarily as a result of increased expenses related to our workforce. The number of employees in our development group increased by approximately 20% from the second quarter of 2008 to the second quarter of 2009 and by approximately 22% from the first half of 2008 to the first half of 2009. Our contractual services expenses, which fluctuate significantly from quarter to quarter based on the timing of activities related to our clinical trials, decreased slightly in the second quarter of 2009 compared to the second quarter of 2008, but were higher in the first half of 2009 as compared to the first half of 2008 due to the timing of expenses related to our telaprevir clinical trials.

        The increases in sales, general and administrative expenses in the three and six months ended June 30, 2009 compared to the same periods in 2008 are the result of increased headcount as we advanced our drug candidates, particularly telaprevir, into late-stage development. In the three months ended June 30, 2009 and 2008, our sales, general and administrative expenses included $6.0 million and $3.3 million, respectively, of stock-based compensation expense. In the six months ended June 30, 2009 and 2008, our sales, general and administrative expenses included $11.0 million and $5.7 million, respectively, of stock-based compensation expense.

    Royalty Expenses

        Royalty expenses decreased slightly in the three and six months ended June 30, 2009 as compared to the three and six months ended June 30, 2008. Royalty expenses primarily relate to a subroyalty payable to a third party on net sales of Lexiva/Telzir and Agenerase. The subroyalty results in both a royalty expense and corresponding royalty revenues. We expect to continue to recognize this subroyalty as an expense in future periods.

    Restructuring Expense

        We recorded restructuring expense of $1.1 million for the three months ended June 30, 2009 compared to $1.2 million for the three months ended June 30, 2008. We recorded restructuring expense of $3.5 million for the six months ended June 30, 2009 compared to $1.8 million for the six months ended June 30, 2008. The restructuring expense in all periods includes imputed interest cost related to the restructuring liability associated with our Kendall Square lease. The increase in restructuring expense for the six months ended June 30, 2009 compared to the six months ended June 30, 2008 was primarily the result of a revision, in the first quarter of 2009, of certain key estimates and assumptions about facility operating costs for the remaining period of the lease commitment, for which there was no corresponding revision in the six months ended June 30, 2008. The lease restructuring liability was $34.1 million as of June 30, 2009.

        We review our estimates and assumptions with respect to the Kendall Square lease on at least a quarterly basis, and will make whatever modifications we believe are necessary to reflect any changed circumstances, based on our best judgment, until the termination of the lease. Our estimates have changed in the past, and may change in the future, resulting in additional adjustments to the estimate of the liability, and the effect of any such adjustments could be material.

    Acquisition-related Expenses

        We incurred $7.8 million of expenses in the six months ended June 30, 2009, all in the first quarter, in connection with our acquisition of ViroChem, including $5.7 million in transaction expenses and $2.1 million related to a restructuring of ViroChem's operations that we undertook in March 2009 in order to focus ViroChem's activities on its HCV assets. We did not have corresponding acquisition-related expenses in the six months ended June 30, 2008.

Non-operating Items—Other Income (Expense)

        Interest income decreased by $2.5 million, or 63%, to $1.5 million for the three months ended June 30, 2009 from $4.0 million for the three months ended June 30, 2008. Interest income decreased by $4.4 million, or 52%, to $4.1 million for the six months ended June 30, 2009 from $8.5 million for the six months ended June 30, 2008. The decrease was a result of lower portfolio yields during the 2009 period as compared to the 2008 period. Our cash, cash equivalents and marketable securities yielded approximately 1% on an annual basis in the second quarter of 2009 compared to approximately 2% on an annual basis in the second quarter of 2008.

        Interest expense decreased by $0.5 million, or 13%, to $3.3 million for the three months ended June 30, 2009 from $3.8 million for the three months ended June 30, 2008. Interest expense was $6.7 million and $5.7 million, respectively, for the six months ended June 30, 2009 and June 30, 2008. We recorded interest expense of $2.1 million on the $143.5 million in aggregate principal amount of 2013 Notes that were exchanged in June 2009 through the date on which we entered into the exchange agreements with respect to such 2013 Notes. Our outstanding principal amount of 2013 Notes decreased from $287.5 million on March 31, 2009 to $144.0 million on June 30, 2009. As a result, we expect that interest expense will decrease significantly in the second half of 2009 as compared to the second half of 2008.

        In the three months ended June 30, 2009, we incurred a non-cash charge of $12.3 million in connection with the exchange of $143.5 million in aggregate principal amount of the 2013 Notes for 6.6 million newly-issued shares of our common stock. The charge related to the additional approximately 400,000 shares of common stock that we issued in excess of the number of shares of common stock into which such 2013 Notes were convertible prior to the exchange.

Liquidity and Capital Resources

        We have incurred operating losses since our inception and have financed our operations principally through public and private offerings of our equity and debt securities, strategic collaborative agreements that include research and/or development funding, development milestones and royalties on the sales of products, strategic sales of assets or businesses, investment income and proceeds from the issuance of common stock under our employee benefit plans. We expect that we will require additional capital in order to commercialize telaprevir and continue our planned activities in other areas.

        At June 30, 2009, we had cash, cash equivalents and marketable securities of $754.4 million, which was a decrease of $77.7 million from $832.1 million at December 31, 2008. The decrease was the result of cash expenditures we made in the six months ended June 30, 2009 related to, among other things, research and development expenses and sales, general and administrative expenses, $100.0 million in cash that we paid for ViroChem, and the timing of payments to our vendors. These cash expenditures were largely offset by the $313.3 million of net proceeds from the offering of common stock that we completed in February 2009. In addition, we received payments from our collaborators and $16.6 million from the issuance of common stock under our employee benefits plans. Capital expenditures for property and equipment during the six months ended June 30, 2009 were $11.2 million.

        During the three months ended June 30, 2009, we reduced the aggregate principal amount of our 2013 Notes outstanding from $287.5 million to $144.0 million. The 2013 Notes bear interest at the rate of 4.75% per annum, and we are required to make semi-annual interest payments on the outstanding principal balance of the 2013 Notes on February 15 and August 15 of each year. The 2013 Notes will mature on February 15, 2013. The 2013 Notes are convertible, at the option of the holder, into our common stock at a price equal to approximately $23.14 per share, subject to adjustment. On or after February 15, 2010, we may redeem the 2013 Notes at our option, in whole or in part, at the redemption prices stated in the indenture related to the 2013 Notes, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

        Our accrued restructuring expense of $34.1 million at June 30, 2009 relates to the portion of the facility that we lease in Kendall Square that we do not intend to occupy and includes other related lease obligations, recorded at net present value. In the six months ended June 30, 2009, we made cash payments of $7.8 million against the accrued expense and received $4.2 million in sublease rental payments. During the second half of 2009, we expect to make additional cash payments of $7.5 million against the accrued expense and receive $4.2 million in sublease rental payments.

        We expect to continue to make significant investments in our development pipeline, particularly in clinical trials of telaprevir, in our effort to prepare for potential registration, regulatory approval and commercial launch of telaprevir, and in clinical trials for our other drug candidates, including VX-770. We also expect to maintain our substantial investment in research. As a result, we expect to incur future losses on a quarterly and annual basis. The adequacy of our available funds to meet our future operating and capital requirements will depend on many factors, including the number, breadth and prospects of our discovery and development programs, the costs and timing of obtaining regulatory approvals for any of our drug candidates and our decisions regarding manufacturing and commercial investments.

        We believe that our current cash, cash equivalents and marketable securities, in addition to amounts we expect to receive from our collaborators under existing contractual obligations, will be sufficient to fund our operations for at least the next twelve months. We expect that we will need additional capital in order to complete the development and commercialization of telaprevir and to continue the development of our other drug candidates, including VX-770. We may raise additional capital through public offerings or private placements of our securities, securing new collaborative agreements, or other methods of financing. Any such capital transactions may or may not be similar to

45


Table of Contents


transactions in which we have engaged in the past. We also will continue to manage our capital structure and consider all financing opportunities, whenever they may occur, that could strengthen our long-term liquidity profile. There can be no assurance that any such financing opportunities will be available on acceptable terms, if at all. If adequate funds are not available, we may be required to curtail significantly or discontinue one or more of our research, drug discovery or development programs or attempt to obtain funds through arrangements that may require us to relinquish rights to certain of our technologies or drug candidates.

Contractual Commitments and Obligations

        Our commitments and obligations were reported in our Annual Report on Form 10-K for the year ended December 31, 2008, which was filed with the Securities and Exchange Commission, or SEC, on February 17, 2009. There have been no material changes from the contractual commitments and obligations previously disclosed in that Annual Report on Form 10-K, except that as a result of the exchanges of $143.5 million of our outstanding 2013 Notes for 6.6 million newly-issued shares of our common stock in June 2009, the principal amount on the 2013 Notes that we are obligated to repay in 2013 has been reduced to $144.0 million from $287.5 million. In addition, the interest payment on the 2013 Notes that we are obligated to make in August 2009 is reduced from $6.8 million to $3.4 million, and the interest payments we are obligated to make in 2010, 2011, 2012 and 2013 have been reduced by $6.8 million, $6.8 million, $6.8 million and $3.4 million, respectively.

Recent Accounting Pronouncements

        In June 2009, the FASB issued SFAS No. 167, "Amendments to FASB Interpretation No. 46(R)" ("SFAS 167"). SFAS 167 requires a qualitative approach to identifying a controlling financial interest in a variable interest entity ("VIE"), and requires ongoing assessment of whether an entity is a VIE and whether an interest in a VIE makes the holder the primary beneficiary of the VIE. SFAS 167 is effective for us on January 1, 2010. We are evaluating the effect of the pending adoption of SFAS 167 on our condensed consolidated financial statements.

        In June 2009, the FASB issued SFAS No. 166, "Accounting for Transfers of Financial Assets—an amendment of FASB Statement No. 140" ("SFAS 166"). SFAS 166 amends FASB Statement No. 140 to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor's continuing involvement in transferred financial assets. The recognition and measurement provisions of this statement shall be applied to transfers that occur on or after January 1, 2010, the effective date of SFAS 166 for us. We are evaluating the effect of the pending adoption of SFAS 167 on our condensed consolidated financial statements.

        In April 2009, the FASB issued three FASB Staff Positions ("FSP"s) that are intended to provide additional application guidance and enhance disclosures about fair value measurements and impairments of securities. FSP No. FAS 157-4, "Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly," clarifies the objective and method of fair value measurement even when there has been a significant decrease in market activity for the asset being measured. FSP No. FAS 115-2 and FAS 124-2, "Recognition and Presentation of Other-Than-Temporary Impairments," establishes a new model for measuring other-than-temporary impairments for debt securities, including establishing criteria for when to recognize a write-down through earnings instead of other comprehensive income. FSP No. FAS 107-1 and APB 28-1, "Interim Disclosures about Fair Value of Financial Instruments," expands the fair value disclosures required for all financial instruments within the scope of FASB Statement No. 107, "Disclosures about Fair Value of Financial Instruments," to interim periods. All of these FSPs became effective for us on April 1, 2009. FSP No. FAS 157-4, FSP No. FAS 115-2 and

46


Table of Contents


FAS 124-2, and FSP No. FAS 107-1 and APB 28-1 did not have an effect on our condensed consolidated financial statements.

        In April 2009, the FASB issued FSP No. FAS 141(R)-1, "Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies," which amends SFAS 141(R) by establishing a model to account for certain pre-acquisition contingencies. In November 2008, the FASB ratified Emerging Issues Task Force ("EITF") Issue No. 08-7, "Accounting for Defensive Intangible Assets" ("EITF 08-7"). EITF 08-7 applies to defensive intangible assets, which are acquired intangible assets that the acquirer does not intend to actively use but intends to hold to prevent its competitors from obtaining access to them. FSP No. FAS 141(R)-1 and EITF 08-7 became effective on January 1, 2009. The implementation of FSP No. FAS 141(R)-1 and EITF 08-7 did not have an effect on our condensed consolidated financial statements.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

        As part of our investment portfolio, we own financial instruments that are sensitive to market risks. The investment portfolio is used to preserve our capital until it is required to fund operations, including our research and development activities. None of these market risk-sensitive instruments are held for trading purposes. We do not have derivative financial instruments in our investment portfolio.

Interest Rate Risk

        We invest our cash in a variety of financial instruments, principally securities issued by the United States government and its agencies, investment grade commercial paper and money market funds. These investments are denominated in United States dollars. All of our interest-bearing securities are subject to interest rate risk, and could decline in value if interest rates fluctuate. Substantially all of our investment portfolio consists of marketable securities with active secondary or resale markets to help ensure portfolio liquidity, and we have implemented guidelines limiting the term-to-maturity of our investment instruments. Due to the conservative nature of these instruments, we do not believe that we have a material exposure to interest rate risk.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

        Our chief executive officer and chief financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q, have concluded that, based on such evaluation, as of June 30, 2009 our disclosure controls and procedures were effective and designed to provide reasonable assurance that the information required to be disclosed is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Controls Over Financial Reporting

        No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) occurred during the second quarter of 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 1A.    Risk Factors

        Information regarding risk factors appears in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2008, which was filed with the SEC on February 17, 2009, as updated by our Quarterly Report on Form 10-Q for the three months ended March 31, 2009, which was filed with the SEC on May 11, 2009. There have been no material changes from the risk factors previously disclosed in the Form 10-K as updated by the Form 10-Q.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This Quarterly Report on Form 10-Q and, in particular, our Management's Discussion and Analysis of Financial Condition and Results of Operations set forth in Part I—Item 2, contain or incorporate a number of forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding:

    our expectations regarding clinical trials, development timelines and regulatory authority filings for telaprevir, VX-770, VX-809, VX-222 and other drug candidates under development by us and our collaborators including our intention to submit an NDA for telaprevir in the United States in the second half of 2010;

    our expectations regarding the number of patients that will be evaluated, the trial design that will be utilized, and the expected date by which SVR data, interim data and/or final data will be available and/or publicly announced for our ADVANCE, REALIZE and ILLUMINATE trials, the other ongoing or planned clinical trials of telaprevir, the ENDEAVOR registration program for VX-770, including the STRIVE, ENVISION and DISCOVER trials, the Phase 2a clinical trials of VX-809, the Phase 1 clinical trial of VX-222, and the clinical trials being conducted by our collaborators of drug candidates for the treatment of cancer;

    expectations regarding the amount of, timing of and trends with respect to our revenues and costs and expenses;

    the data that will be generated by ongoing and planned clinical trials, and the ability to use that data for the design and initiation of further clinical trials and to support regulatory filings, including potentially applications for marketing approval for telaprevir and VX-770;

    our ability to potentially register telaprevir for marketing across a range of genotypes and patient populations;

    our plan to begin clinical evaluation of novel combination regimens of telaprevir with VX-222 as early as the fourth quarter of 2009;

    our expectations regarding the future market demand and medical need for telaprevir and our other drug candidates;

    our beliefs regarding the support provided by clinical trials and preclinical and nonclinical studies of our drug candidates for further investigation, clinical trials or potential use as a treatment of those drug candidates;

    our ability to successfully market telaprevir and VX-770 if we are able to obtain regulatory approval;

    the focus of our drug development efforts and our financial and management resources and our plan to invest significant resources in telaprevir and our other drug candidates;

    the establishment, development and maintenance of collaborative relationships;

Table of Contents

    potential business development activities, including with respect to our JAK3 program and our telaprevir milestones;

    our ability to use our research programs to identify and develop new drug candidates to address serious diseases and significant unmet medical needs;

    our estimates regarding obligations associated with a lease of a facility in Kendall Square, Cambridge, Massachusetts; and

    our liquidity and our expectations regarding our needs for and ability to raise additional capital.

        Without limiting the foregoing, the words "believes," "anticipates," "plans," "intends," "expects" and similar expressions are intended to identify forward-looking statements. Any or all of our forward-looking statements in this Quarterly Report on Form 10-Q may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in our discussion in this Quarterly Report on Form 10-Q will be important in determining future results. Consequently, no forward- looking statement can be guaranteed. Actual future results may vary materially from expected results. We also provide a cautionary discussion of risks and uncertainties under "Risk Factors" in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2008, which was filed with the SEC on February 17, 2009, and updated and supplemented by "Part II—Item 1A—Risk Factors" of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2009, which was filed with the SEC on May 11, 2009. These are factors that we think could cause our actual results to differ materially from expected results. Other factors besides those listed could also adversely affect us. In addition, the forward-looking statements contained herein represent our estimate only as of the date of this filing and should not be relied upon as representing our estimate as of any subsequent date. While we may elect to update these forward-looking statements at some point in the future, we specifically disclaim any obligation to do so to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements.

    22,622   $ 0.01          

        The repurchases were made under the terms of our 1996 Stock and Option Plan and 2006 Stock and Option Plan. Under these plans, we award shares of restricted stock that typically are subject to a lapsing right of repurchase by us. We may exercise this right of repurchase in the event that a restricted stock recipient's service to us is terminated. If we exercise this right, we are required to repay the purchase price paid by or on behalf of the recipient for the repurchased restricted shares, which typically is the par value per share of $0.01. Repurchased shares are returned to the applicable Stock and Option Plan under which they were issued. Shares returned to the 2006 Stock and Option Plan are available for future awards under the terms of that plan.
