PART I

ITEM 1.    BUSINESS

Overview

        Theravance is a biopharmaceutical company with a pipeline of internally discovered product candidates and strategic collaborations with pharmaceutical companies. We are focused on the discovery, development and commercialization of small molecule medicines across a number of therapeutic areas including respiratory disease, bacterial infections, and central nervous system (CNS)/pain. Our key programs include: RELOVAIR™, LAMA/LABA ('719/vilanterol (VI)) and MABA (Bifunctional Muscarinic Antagonist-Beta2 Agonist), each partnered with GlaxoSmithKline plc (GSK), and our oral Peripheral Mu Opioid Receptor Antagonist (PµMA) program. By leveraging our proprietary insight of multivalency to drug discovery, we are pursuing a best-in-class strategy designed to discover superior medicines in areas of significant unmet medical need. Our headquarters are located at 901 Gateway Boulevard, South San Francisco, California 94080. Theravance was incorporated in Delaware in November 1996 under the name Advanced Medicine, Inc. and began operations in May 1997. The Company changed its name to Theravance, Inc. in April 2002.

        Our strategy focuses on the discovery, development and commercialization of medicines with superior efficacy, convenience, tolerability and/or safety. Our proprietary approach combines chemistry and biology to discover new product candidates using our expertise in multivalency. Multivalency refers to the simultaneous attachment of a single molecule to multiple binding sites on one or more biological targets. When compared to monovalency, whereby a molecule attaches to only one binding site, multivalency can significantly increase a compound's potency, duration of action and/or selectivity. Multivalent compounds generally consist of several individual small molecules, at least one of which is biologically active when bound to its target, joined by linking components. In addition, we believe that we can enhance the probability of successfully developing and commercializing medicines by identifying at least two structurally different product candidates, whenever practicable, in each therapeutic program.

Table of Contents

        In total, our research and development expenses, including stock-based compensation expense, incurred for all of our therapeutic programs in 2011, 2010, and 2009 were $103.5 million, $75.1 million and $77.5 million, respectively.

        We have entered into the following respiratory collaboration arrangements with GSK:

        In November 2002, we entered into our long-acting beta2 agonist (LABA) collaboration with GSK to develop and commercialize once-daily LABA products for the treatment of chronic obstructive pulmonary disease (COPD) and asthma. For the treatment of COPD, the collaboration is developing combination products, RELOVAIR™ and the LAMA/LABA '719/VI. For the treatment of asthma, the collaboration is developing RELOVAIR™. RELOVAIR™ is an investigational once-daily inhaled corticosteroid (ICS)/LABA combination treatment, comprising fluticasone furoate and vilanterol (FF/VI). '719/VI is an investigational once-daily combination medicine consisting of the long-acting muscarinic antagonist (LAMA) GSK573719 ('719) and the LABA, VI.

        In March 2004, we entered into our strategic alliance agreement with GSK under which GSK received an option to license certain of our discovery programs on pre-determined terms and on an exclusive, worldwide basis. In 2005, GSK licensed our MABA program under this agreement and in October 2011, we and GSK expanded the MABA program by adding six additional Theravance-discovered preclinical MABA compounds.

        Astellas Pharma Inc. (Astellas) recently exercised its right to terminate our 2005 collaboration arrangement for the development and commercialization of VIBATIV® (telavancin), a bactericidal, once-daily injectable antibiotic developed by us for the treatment of Gram-positive infections, including methicillin-resistant Staphylococcus aureus. The U.S. Food and Drug Administration (FDA) has approved VIBATIV® for the treatment of complicated skin and skin structure infections (cSSSI) caused by susceptible Gram-positive bacteria, including both methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) strains of Staphylococcus aureus, in adult patients. VIBATIV® is also approved in Canada for the treatment of cSSSI in adult patients. In September 2011, the European Commission granted marketing authorization for VIBATIV® for the treatment of adults with nosocomial pneumonia, including ventilator-associated pneumonia, known or suspected to be caused by MRSA when other alternatives are not suitable. However, in February 2012 the Committee for Medicinal Products for Human Use (CHMP) recommended to the European Commission that it suspend this marketing authorization because the single-source VIBATIV® drug product supplier does not meet the Good Manufacturing Practice (GMP) requirements to allow the manufacture of VIBATIV®. We currently are focused on evaluating commercialization alternatives for VIBATIV®, including re-partnering, and re-establishing consistent VIBATIV® product supply. Due to the supplier's manufacturing issues, VIBATIV® is currently subject to critical product shortages and regional supply outages in the U.S. If the issues at the manufacturer are not promptly resolved, obtaining supply would require identifying and qualifying an alternative manufacturer, which could take 12 to 24 months.

Our Programs

        Our drug discovery efforts are based on the principles of multivalency. Multivalency involves the simultaneous attachment of a single molecule to multiple binding sites on one or more biological targets. We have applied our expertise in multivalency to discover product candidates and lead compounds in a wide variety of therapeutic areas. We have conducted extensive research in both relevant laboratory and animal models to demonstrate that by applying the design principles of multivalency, we can achieve significantly stronger and more selective attachment of our compounds to a variety of intended biological targets. We believe that medicines that attach more strongly and selectively to their targets will be superior to many medicines by substantially improving potency, duration of action and/or safety.

Our Relationship with GlaxoSmithKline

LABA collaboration with GSK

        In November 2002, we entered into our LABA collaboration with GSK to develop and commercialize once-daily LABA products for the treatment of COPD and asthma. For the treatment of COPD, the collaboration is developing combination products, RELOVAIR™ and the LAMA/LABA '719/VI. For the treatment of asthma, the collaboration is developing RELOVAIR™. RELOVAIR™ is an investigational once-daily combination medicine consisting of a LABA, VI, previously referred to as GW642444 or '444, and an ICS, fluticasone furoate (FF). The LAMA/LABA, '719/VI, is an investigational once-daily combination medicine consisting of the LAMA, '719, and the LABA, VI. The RELOVAIR™ program is aimed at developing a once-daily combination LABA/ICS to succeed GSK's Advair®/Seretide™ (salmeterol and fluticasone as a combination) franchise, which reported 2011 sales of approximately $8.1 billion, and to compete with Symbicort® (formoterol and budesonide as a combination), which reported 2011 sales of approximately $3.1 billion. '719/VI, which is also a combination product, is targeted as an alternative treatment option to Spiriva® (tiotropium), a once-daily, single-mechanism bronchodilator, which reported 2010 sales of approximately $3.8 billion.

        The current lead product candidates in the LABA collaboration, VI and FF, were discovered by GSK. In the event that VI is successfully developed and commercialized, we will be obligated to make milestone payments to GSK which could total as much as $220.0 million if both a single-agent and a combination product or two different combination products are launched in multiple regions of the world. If global regulatory authorities accept the applications for RELOVAIR™, which we anticipate will be filed by GSK beginning in mid-2012, a portion of these potential milestone payments could be payable to GSK within the next two years. We are entitled to annual royalties from GSK of 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. Sales of single-agent LABA medicines and combination medicines would be combined for the purposes of this royalty calculation. For other products combined with a LABA from the LABA collaboration, such as '719/VI, royalties are upward tiering and range from the mid-single digits to 10%. However, if GSK is not selling a LABA/ICS combination product at the time that the first other LABA combination is launched, then the royalties described above for the LABA/ICS combination medicine would be applicable.

        In connection with the LABA collaboration, in 2002, Glaxo Group Limited, an affiliate of GSK, purchased shares of our Series E preferred stock for an aggregate purchase price of $40.0 million.

2004 Strategic Alliance with GSK

        In March 2004, we entered into our strategic alliance with GSK. Under this alliance, GSK received an option to license exclusive development and commercialization rights to product candidates from certain of our discovery programs on pre-determined terms and on an exclusive, worldwide basis. Upon GSK's decision to license a program, GSK is responsible for funding all future development, manufacturing and commercialization activities for product candidates in that program. In addition, GSK is obligated to use diligent efforts to develop and commercialize product candidates from any program that it licenses. If the program is successfully advanced through development by GSK, we are entitled to receive clinical, regulatory and commercial milestone payments and royalties on any sales of medicines developed from the program. If GSK chooses not to license a program, we retain all rights to the program and may continue the program alone or with a third party.

        In 2005, GSK licensed our MABA program for the treatment of COPD, and in October 2011, we and GSK expanded the MABA program by adding six additional Theravance-discovered preclinical MABA compounds (the "Additional MABAs"). GSK's development, commercialization, milestone and royalty obligations under the strategic alliance remain the same with respect to '081, the lead compound in the MABA program. GSK is obligated to use diligent efforts to develop and commercialize at least one MABA within the MABA program, but may terminate progression of any or all Additional MABAs at any time and return them to us, at which point we may develop and commercialize such Additional MABAs alone or with a third party. Both GSK and we have agreed not to conduct any MABA clinical studies outside of the strategic alliance so long as GSK is in possession of the Additional MABAs. If a single-agent MABA medicine containing '081 is successfully developed and commercialized, we are entitled to receive royalties from GSK of between 10% and 20% of annual global net sales up to $3.5 billion, and 7.5% for all annual global net sales above $3.5 billion. If a MABA medicine containing '081 is commercialized only as a combination product, such as a MABA/ICS, the royalty rate is 70% of the rate applicable to sales of the single-agent MABA medicine. For single-agent MABA medicines containing an Additional MABA, we are entitled to receive royalties from GSK of between 10% and 15% of annual global net sales up to $3.5 billion, and 10% for all annual global net sales above $3.5 billion. For combination products containing an Additional MABA, such as a MABA/ICS, the royalty rate is 50% of the rate applicable to sales of the single-agent MABA medicine. If a MABA medicine containing '081 is successfully developed and commercialized in multiple regions of the world, we could earn total milestone payments up to $125.0 million for a single-agent medicine and up to $250.0 million for both a single-agent and a combination medicine. If a MABA medicine containing an Additional MABA is successfully developed and commercialized in multiple regions of the world, we could earn total milestone payments up to $129.0 million.

        In connection with the expansion of the MABA program, GSK relinquished its option right on our MonoAmine Reuptake Inhibitor (MARIN) program and Angiotensin Receptor-NEP Inhibitor (ARNI) program. GSK has no further option rights on any of our research or development programs under the strategic alliance.

        In May 2004, GlaxoSmithKline LLC, an affiliate of GSK, purchased 6,387,096 shares of our Class A common stock for an aggregate purchase price of $108.9 million and, upon the closing of our initial public offering on October 8, 2004, GlaxoSmithKline LLC purchased an additional 433,757 shares of Class A common stock for an aggregate purchase price of $6.9 million. In November 2010 Glaxo Group Limited, an affiliate of GSK, purchased 5,750,000 shares of our Common Stock for an aggregate purchase price of $129.4 million.

Program Highlights

Respiratory Programs with GSK

RELOVAIR™

        RELOVAIR™ is an investigational once-daily ICS/LABA combination treatment, comprising FF/VI, currently in development for the treatment of patients with COPD or asthma.

        In January 2012, we and GSK announced that GSK intends to commence global regulatory filings in COPD and asthma beginning in mid-2012 based upon the initial outcomes from pivotal Phase 3 studies for once-daily RELOVAIR™ in COPD and asthma. For asthma, GSK will continue discussions with the FDA on the regulatory requirements for a U.S. asthma indication.

LAMA/LABA Combination (GSK573719/Vilanterol or '719/VI)

        Enrollment is complete for the seven ongoing studies in the Phase 3 program for the once-daily LAMA/LABA dual bronchodilator '719/VI. '719/VI combines two bronchodilators currently under development—'719, a LAMA and VI, a LABA. These two molecules provide two mechanisms of bronchodilation for patients with COPD: antagonism of acetylcholine muscarinic receptors and agonism of beta2 adrenoreceptors.

        The LAMA/LABA Phase 3 program, which will evaluate over 5,000 patients with COPD globally, consists of a 52-week study to evaluate the long term safety and tolerability of '719 (125mcg) alone, as well as the combination '719/VI (125/25mcg), two large 6-month pivotal studies that will compare improvements in lung function between '719/VI, its components and placebo, two 6-month studies to compare the combination with its components and tiotropium and two studies to assess the effect of '719/VI on exercise endurance. The Phase 3 program will investigate two doses of '719 (125mcg and 62.5mcg) and two doses of the combination '719/VI (125/25mcg and 62.5/25mcg).

Inhaled Bifunctional Muscarinic Antagonist-Beta2 Agonist (MABA)

        GSK961081 ('081), the lead compound in the MABA program with GSK, is a single molecule bifunctional bronchodilator with both muscarinic antagonist and beta2 receptor agonist activity. In February 2012, we announced topline results from a Phase 2b COPD study with '081.

Table of Contents

        In October 2011, we and GSK amended the 2004 Strategic Alliance Agreement to expand the MABA program. We granted to GSK an exclusive license to develop and commercialize additional preclinical MABA compounds discovered by Theravance. We received an upfront license payment of $1.0 million and have the potential to receive clinical, regulatory and commercial milestone payments as well as royalties on worldwide net sales if one of these MABA compounds is successfully commercialized. In connection with this amendment, we regained full rights to our MonoAmine Reuptake INhibitor (MARIN) program, which is currently in Phase 2 development, and our Angiotensin Receptor-NEP Inhibitor (ARNI) program in preclinical development.

Bacterial Infections Program

VIBATIV® (telavancin) for injection

        On January 6, 2012, Astellas exercised its right to terminate our VIBATIV® collaboration agreement and we regained full global rights to VIBATIV®, our once-daily injectable lipoglycopeptide antibiotic approved in the U.S. and Canada. We currently are focusing our efforts on evaluating commercialization alternatives for VIBATIV®, including re-partnering, and re-establishing consistent VIBATIV® product supply.

Central Nervous System (CNS)/Pain Program

Oral Peripheral Mu Opioid Receptor Antagonist (PµMA)—TD-1211

        Enrollment is progressing in the Phase 2b program, which will assess the safety, tolerability and clinical activity of TD-1211 in patients with opioid-induced constipation. This program is evaluating several doses and dose regimens to provide information for the design of the Phase 3 program. TD-1211 is an investigational once-daily, orally-administered, peripherally selective, multivalent inhibitor of the mu opioid receptor designed to alleviate gastrointestinal side effects of opioid therapy without affecting analgesia.

MonoAmine Reuptake INhibitor (MARIN)—TD-9855

        In December 2011, we announced the initiation of an Attention-Deficit/Hyperactivity Disorder (ADHD) Phase 2 proof-of-concept study with TD-9855, the lead compound in our MARIN program. This Phase 2 study will evaluate the safety and efficacy of two different doses of TD-9855 in adult male patients with ADHD. TD-9855 is an investigational norepinephrine and serotonin reuptake inhibitor (NSRI) discovered by Theravance for the treatment of CNS conditions such as ADHD and chronic pain.

Theravance Respiratory Program

Long-Acting Muscarinic Antagonist (LAMA)—TD-4208

        In November 2011, we announced positive topline results from a Phase 2a single-dose COPD study of TD-4208, an investigational inhaled LAMA, discovered by Theravance. In this study, TD-4208 met the primary endpoint by demonstrating a statistically significant mean change from baseline in peak forced expiratory volume in one second (FEV1) compared to placebo, and was generally well tolerated.

Other Programs

        In addition to the programs listed above, we have other clinical-stage programs for bacterial infections, cognitive disorders and gastrointestinal motility.

Table of Contents

        TD-1792 is our investigational heterodimer antibiotic that combines the antibacterial activities of a glycopeptide and a beta-lactam in one molecule. The goal of our program with TD-1792 is to develop a next-generation antibiotic for the treatment of serious infections caused by Gram-positive bacteria.

        In cognitive disorders, we are evaluating compound TD-5108 as a potential treatment for Alzheimer's disease. TD-5108 has successfully completed a Phase 1 study assessing CNS penetration. Our Gastrointestinal (GI) Motility Dysfunction program is dedicated to finding new medicines for GI motility disorders such as chronic idiopathic constipation (CIC) and other disorders related to reduced gastrointestinal motility. Our lead compound in this area is TD-5108, a highly selective 5-HT4 receptor agonist that has successfully completed a 400 patient Phase 2 proof-of-concept study in CIC. The back-up compound in this program, TD-8954, has completed single-ascending and multiple-ascending dose Phase 1 studies.

Multivalency

        Our proprietary approach combines chemistry and biology to discover new product candidates using our expertise in multivalency. Multivalency refers to the simultaneous attachment of a single molecule to multiple binding sites on one or more biological targets. When compared to monovalency, whereby a molecule attaches to only one binding site, multivalency can significantly increase a compound's potency, duration of action and/or selectivity. Multivalent compounds generally consist of several individual small molecules, at least one of which is biologically active when bound to its target, joined by linking components.

        Our approach is based on an integration of the following insights:

Our Strategy

        Our objective is to discover, develop and commercialize new medicines with superior efficacy, convenience, tolerability and/or safety. The key elements of our strategy are to:

        Apply our expertise in multivalency to discover and develop superior medicines in areas of significant unmet medical need. We intend to continue to concentrate our efforts on discovering and developing product candidates where:

10


Table of Contents

        Identify two structurally different product candidates in each therapeutic program whenever practicable. We believe that we can increase the likelihood of successfully bringing superior medicines to market by identifying, whenever practicable, two product candidates for development in each program. Our second product candidates are typically in a different structural class from the first product candidate. Applying this strategy can reduce our dependence on any one product candidate and provide us with the potential opportunity to commercialize two compounds in a given area.

        Partner with leading pharmaceutical companies.    Our strategy is to seek collaborations with leading pharmaceutical companies to accelerate development and commercialization of our product candidates at the strategically appropriate time. The LABA collaboration and our strategic alliance with GSK are examples of these types of partnerships.

        Leverage the extensive experience of our people.    We have an experienced senior management team with many years of experience discovering, developing and commercializing new medicines with companies such as Bristol-Myers Squibb Company, Gilead Sciences, Merck & Co. and Pfizer.

        Improve, expand and protect our technical capabilities.    We have created a substantial body of know-how and trade secrets in the application of our multivalent approach to drug discovery. We believe this is a significant asset that distinguishes us from our competitors. We expect to continue to make substantial investments in drug discovery using multivalency and other technologies to maintain what we believe are our competitive advantages.

Manufacturing

        Though we have limited in-house active pharmaceutical ingredient (API) production capabilities, we rely primarily on a number of third parties, including contract manufacturing organizations and our collaborative partners, to produce our active pharmaceutical ingredient and drug product. Manufacturing of compounds in the RELOVAIR™, '719/VI, and MABA programs is handled by GSK, and we are now responsible for manufacture of VIBATIV® as a result of the termination of the VIBATIV® collaboration agreement with Astellas.

        We believe that we have in-house expertise to manage a network of third-party manufacturers. We believe that we will be able to continue to negotiate third-party manufacturing arrangements on commercially reasonable terms and that it will not be necessary for us to obtain internal manufacturing capacity in order to develop or commercialize our products. However, if we are unable to obtain contract manufacturing or obtain such manufacturing on commercially reasonable terms, or if manufacturing is interrupted at one of our suppliers, whether due to regulatory or other reasons, we may not be able to develop or commercialize our products as planned. Due to manufacturing issues at the single-source supplier of VIBATIV® drug product, VIBATIV® is currently subject to critical product shortages and regional supply outages in the U.S. If the issues at the manufacturer are not promptly resolved, obtaining supply would require identifying and qualifying an alternative manufacturer, which could take 12 to 24 months.

Government Regulation

        The development and commercialization of our product candidates and our ongoing research are subject to extensive regulation by governmental authorities in the United States and other countries. Before marketing in the United States, any medicine we develop must undergo rigorous preclinical studies and clinical studies and an extensive regulatory approval process implemented by the FDA under the Federal Food, Drug, and Cosmetic Act. Outside the United States, our ability to market a product depends upon receiving a marketing authorization from the appropriate regulatory authorities. The requirements governing the conduct of clinical studies, marketing authorization, pricing and

11


Table of Contents

reimbursement vary widely from country to country. In any country, however, we will be permitted to commercialize our medicines only if the appropriate regulatory authority is satisfied that we have presented adequate evidence of the safety, quality and efficacy of our medicines.

        Before commencing clinical studies in humans in the United States, we must submit to the FDA an Investigational New Drug application that includes, among other things, the results of preclinical studies. If the FDA accepts the Investigational New Drug submission, clinical studies are usually conducted in three phases and under FDA oversight. These phases generally include the following:

        Phase 1.    The product candidate is introduced into healthy human volunteers and is tested for safety, dose tolerance and pharmacokinetics.

        Phase 2.    The product candidate is introduced into a limited patient population to assess the efficacy of the drug in specific, targeted indications, assess dosage tolerance and optimal dosage, and identify possible adverse effects and safety risks.

        Phase 3.    If a compound is found to be potentially effective and to have an acceptable safety profile in Phase 2 evaluations, the clinical study will be expanded to further demonstrate clinical efficacy, optimal dosage and safety within an expanded patient population.

        The results of product development, preclinical studies and clinical studies must be submitted to the FDA as part of a new drug application, or NDA. The NDA also must contain extensive manufacturing information. NDAs for new chemical entities are subject to performance goals defined in the Prescription Drug User Fee Act (PDUFA) which suggests a goal for FDA action within 6 months for applications that are granted priority review and 10 months for applications that receive standard review. For a product candidate no active ingredient of which has been previously approved by the FDA, the FDA must either refer the product candidate to an advisory committee for review or provide in the action letter on the application for the product candidate a summary of the reasons why the product candidate was not referred to an advisory committee prior to approval. In addition, under the 2009 Food and Drug Administration Amendments Act, the FDA has authority to require submission of a formal Risk Evaluation and Management Strategy (REMS) to ensure safe use of the product. At the end of the review period, the FDA communicates an approval of the NDA or issues a complete response listing the application's deficiencies.

        Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing regulatory standards is not maintained or if safety or quality issues are identified after the product reaches the marketplace. In addition, the FDA may require post-marketing studies, referred to as Phase 4 studies, to monitor the effect of approved products, and may limit further marketing of the product based on the results of these post-marketing studies. The FDA has broad post-market regulatory and enforcement powers, including the ability to suspend or delay issuance of approvals, seize products, withdraw approvals, enjoin violations, and institute criminal prosecution.

        If we obtain regulatory approval for a medicine, this clearance to market the product will be limited to those diseases and conditions for which the medicine is effective, as demonstrated through clinical studies and included in the medicine's labeling. Even if this regulatory approval is obtained, a marketed medicine, its manufacturer and its manufacturing facilities are subject to continual review and periodic inspections by the FDA. The FDA ensures the quality of approved medicines by carefully monitoring manufacturers' compliance with its current Good Manufacturing Practice (cGMP) regulations. The cGMP regulations for drugs contain minimum requirements for the methods, facilities, and controls used in manufacturing, processing, and packing of a medicine. The regulations are intended to make sure that a medicine is safe for use, and that it has the ingredients and strength it claims to have. Discovery of previously unknown problems with a medicine, manufacturer or facility may result in restrictions on the medicine or manufacturer, including costly recalls or withdrawal of the medicine from the market.

        We are also subject to various laws and regulations regarding laboratory practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous substances in connection with our research. In each of these areas, as above, the FDA and other regulatory authorities have broad regulatory and enforcement powers, including the ability to suspend or delay issuance of approvals, seize products, withdraw approvals, enjoin violations, and institute criminal prosecution, any one or more of which could have a material adverse effect upon our business, financial condition and results of operations.

        Outside the United States our ability to market our products will also depend on receiving marketing authorizations from the appropriate regulatory authorities. Risks similar to those associated with FDA approval described above exist with the regulatory approval processes in other countries.

Patents and Proprietary Rights

        We will be able to protect our technology from unauthorized use by third parties only to the extent that our technology is covered by valid and enforceable patents or is effectively maintained as trade secrets. Our success in the future will depend in part on obtaining patent protection for our product candidates. Accordingly, patents and other proprietary rights are essential elements of our business. Our policy is to seek in the United States and selected foreign countries patent protection for novel technologies and compositions of matter that are commercially important to the development of our business. For proprietary know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our drug discovery process that involve proprietary know-how and technology that is not covered by patent applications, we rely on trade secret protection and confidentiality agreements to protect our interests. We require all of our employees, consultants and advisors to enter into confidentiality agreements. Where it is necessary to share our proprietary information or data with outside parties, our policy is to make available only that information and data required to accomplish the desired purpose and only pursuant to a duty of confidentiality on the part of those parties.

        As of December 31, 2011, we owned 271 issued United States patents and 907 granted foreign patents, as well as additional pending United States patent applications and foreign patent applications. The claims in these various patents and patent applications are directed to compositions of matter, including claims covering product candidates, lead compounds and key intermediates, pharmaceutical compositions, methods of use and processes for making our compounds along with methods of design, synthesis, selection and use relevant to multivalency in general and to our research and development programs in particular. In particular, we own the following U.S. patents which are listed in the FDA Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book) for telavancin: U.S. Patent No. 6,635,618 B2, expiring on September 22, 2021; U.S. Patent No. 6,858,584 B2, expiring on August 24, 2022; U.S. Patent No. 6,872,701 B2, expiring on June 5, 2021; U.S. Patent No. 7,008,923 B2, expiring on May 6, 2021; U.S. Patent No. 7,208,471 B2, expiring on May 1, 2021; U.S. Patent No. 7,351,691 B2, expiring on May 1, 2021; U.S. Patent No. 7,531,623 B2, expiring on January 1, 2027; U.S. Patent No. 7,544,364 B2, expiring on May 1, 2021; and U.S. Patent No. 7,700,550 B2, expiring on May 1, 2021. On October 15, 2010, we filed patent term extension (PTE) applications in the United States Patent and Trademark Office (USPTO) for U.S. Patent Nos. 6,635,618 B2; 6,872,701 B2; and 7,208,471 B2. These PTE applications are currently pending and if granted, we will be permitted to extend the term of one of these patents for the period determined by the USPTO.

        United States issued patents and foreign patents generally expire 20 years after filing. The patent rights relating to telavancin owned by us currently consist of United States patents that expire between 2019 and 2027, additional pending United States patent applications and counterpart patents and patent applications in a number of jurisdictions, including Europe. Nevertheless, issued patents can be challenged, narrowed, invalidated or circumvented, which could limit our ability to stop competitors from marketing similar products and threaten our ability to commercialize our product candidates. Our

13


Table of Contents

patent position, similar to other companies in our industry, is generally uncertain and involves complex legal and factual questions. To maintain our proprietary position we will need to obtain effective claims and enforce these claims once granted. It is possible that, before any of our products can be commercialized, any related patent may expire or remain in force only for a short period following commercialization, thereby reducing any advantage of the patent. Also, we do not know whether any of our patent applications will result in any issued patents or, if issued, whether the scope of the issued claims will be sufficient to protect our proprietary position.

        We have entered into a License Agreement with Janssen Pharmaceutica (Janssen) pursuant to which we have licensed rights under certain patents owned by Janssen covering an excipient used in the formulation of telavancin. We believe that the general and financial terms of the agreement with Janssen are ordinary course terms. Pursuant to the terms of this license agreement, we are obligated to pay royalties and milestone payments to Janssen based on any commercial sales of telavancin. The license is terminable by us upon prior written notice to Janssen or upon an uncured breach or a liquidation event of one of the parties.

Competition

        Our objective is to discover, develop and commercialize new medicines with superior efficacy, convenience, tolerability and/or safety. We expect that any medicines that we commercialize with our collaborative partners or on our own will compete with existing and future market-leading medicines.

        Many of our potential competitors have substantially greater financial, technical and personnel resources than we have. In addition, many of these competitors have significantly greater commercial infrastructures than we have. Our ability to compete successfully will depend largely on our ability to leverage our experience in drug discovery and development to:

        LABA Collaboration with GSK.    We anticipate that, if approved, any product from our LABA collaboration with GSK, including RELOVAIR™ and the LAMA/LABA '719/VI, will compete with a number of approved bronchodilator drugs and drug candidates under development that are designed to treat asthma and COPD. These include but are not limited to Advair®/Seretide® (salmeterol and fluticasone as a combination) marketed by GSK, Foradil®/Oxis® (formoterol) marketed by a number of companies, Symbicort® (formoterol and budesonide as a combination) marketed by AstraZeneca, Dulera® (formoterol and mometasone as a combination) marketed by Merck, and Spiriva® (tiotropium) marketed by Boehringer-Ingelheim and Pfizer. Onbrez® (indacaterol) is marketed in multiple international markets by Novartis and was approved as a single-agent by the FDA during 2011 with launch reportedly planned for early 2012. For markets outside of the United States, Novartis is developing indacaterol in combination with an ICS (mometasone). In addition, indacaterol combined with a muscarinic antagonist is being developed by Novartis. Boehringer-Ingelheim is developing a combination product with tiotropium and the long-acting beta agonist olodaterol for the treatment of COPD. In addition, several firms are reported to be developing new formulations of salmeterol-fluticasone and formoterol-budesonide which may be marketed as generics or branded generics relative to the existing products from GSK and AstraZeneca, respectively. All of these efforts represent potential competition for any product from our LABA collaboration.

        VIBATIV® (telavancin).    VIBATIV® competes with vancomycin, a generic drug that is manufactured by a variety of companies, as well as other drugs marketed to treat complicated skin and skin structure infections caused by Gram-positive bacteria. Currently marketed products include but are not limited to Cubicin® (daptomycin) marketed by Cubist Pharmaceuticals, Zyvox® (linezolid) and Tygacil® (tigecycline) both marketed by Pfizer, and Teflaro® (ceftaroline) marketed by Forest Laboratories. To compete effectively with these medicines, and in particular with the relatively inexpensive generic option of vancomycin, we will need to demonstrate to physicians that, based on experience, clinical data, side-effect profiles and other factors, VIBATIV® is preferable to vancomycin and other existing or subsequently-developed anti-infective drugs in certain clinical situations.

        In addition, as the principles of multivalent medicine design become more widely known and appreciated based on patent and scientific publications and regulatory filings, we expect the field to become highly competitive. Pharmaceutical companies, biotechnology companies and academic and research institutions may seek to develop product candidates based upon the principles underlying our multivalent technologies.

Employees

        As of December 31, 2011, we had 222 employees, 171 of which were engaged primarily in research and development activities. None of our employees are represented by a labor union. We consider our employee relations to be good.

ITEM 1A.    RISK FACTORS

        In addition to the other information in this Annual Report on Form 10-K, the following risk factors should be considered carefully in evaluating our business and us.

Risks Related to our Business

If regulatory authorities determine that the RELOVAIR™ Phase 3 program in asthma or chronic obstructive pulmonary disease (COPD) does not demonstrate safety and efficacy, the RELOVAIR™ program will be significantly delayed or terminated, our business will be harmed, and the price of our securities could fall.

        The RELOVAIR™ Phase 3 registrational program for COPD concluded in late 2011 and we currently expect the RELOVAIR™ Phase 3 registrational program for asthma to conclude in the first half of 2012. The RELOVAIR™ Phase 3b program for COPD commenced in February 2011. In early 2012, we and GSK reported topline results from the Phase 3 registrational program for COPD and all but one study from the Phase 3 registrational program for asthma. In connection with reporting these topline results, GSK announced its intention (i) to submit in 2012 regulatory applications in the U.S. and Europe for COPD and an application in Europe for asthma, and (ii) to continue discussions with the U.S. Food and Drug Administration (FDA) on the regulatory requirements for a U.S. asthma indication. Any adverse developments or results or perceived adverse developments or results with

15


Table of Contents

respect to the RELOVAIR™ program will significantly harm our business and could cause the price of our securities to fall. Examples of such adverse developments include, but are not limited to:

        On February 18, 2010, the FDA announced that LABAs should not be used alone in the treatment of asthma and will require manufacturers to include this warning in the product labels of these drugs, along with taking other steps to reduce the overall use of these medicines. The FDA now requires that the product labels for LABA medicines reflect, among other things, that the use of LABAs is contraindicated without the use of an asthma controller medication such as an inhaled corticosteroid, that LABAs should only be used long-term in patients whose asthma cannot be adequately controlled on asthma controller medications, and that LABAs should be used for the shortest duration of time required to achieve control of asthma symptoms and discontinued, if possible, once asthma control is achieved. In addition, on March 10 and 11, 2010, the FDA held an Advisory Committee to discuss the design of medical research studies (known as "clinical trial design") to evaluate serious asthma outcomes (such as hospitalizations, a procedure using a breathing tube known as intubation, or death) with the use of LABAs in the treatment of asthma in adults, adolescents, and children. Further, in April 2011, the FDA announced that to further evaluate the safety of LABAs, it is requiring the manufacturers of currently marketed LABAs to conduct additional randomized, double-blind, controlled clinical trials comparing the addition of LABAs to inhaled corticosteroids versus inhaled corticosteroids alone. Results from these post-marketing studies are expected in 2017. It is unknown at this time what, if any, effect these or future FDA actions will have on the development of RELOVAIR™. The current uncertainty regarding the FDA's position on LABAs for the treatment of asthma and the lack of consensus expressed at the March 2010 Advisory Committee may result in increased time and cost of the asthma clinical trials in the United States for RELOVAIR™ and increase the overall risk of the RELOVAIR™ asthma program in the United States.

If the '719/VI Phase 3 program for the treatment of COPD does not demonstrate safety and efficacy, the '719/VI program will be significantly delayed or terminated, our business will be harmed, and the price of our securities could fall.

        The '719/VI Phase 3 program with the combination of the LABA, VI, and the LAMA GSK573719, or '719, for the treatment of COPD commenced in February 2011. Any adverse developments or results or perceived adverse developments or results with respect to the '719/VI program will significantly

16


Table of Contents

harm our business and could cause the price of our securities to fall. Examples of such adverse developments include, but are not limited to:

If the MABA program for the treatment of COPD does not demonstrate safety and efficacy, the MABA program will be significantly delayed or terminated, our business will be harmed, and the price of our securities could fall.

        The lead compound, GSK961081 ('081), in the bifunctional muscarinic antagonist-beta2 agonist (MABA) program with GSK recently completed a Phase 2b study and a Phase 1 study in combination with fluticasone propionate (FP), an inhaled corticosteroid (ICS), and a number of Phase 3-enabling non-clinical studies are ongoing. We announced topline results from the Phase 2b COPD study in February 2012 and progression into Phase 3 is dependent upon successful completion of the Phase 3-enabling studies. Any adverse developments or results or perceived adverse developments or results with respect to these studies will harm our business and could cause the price of our securities to fall. Examples of such adverse developments include, but are not limited to:

Our collaboration agreement for VIBATIV® was terminated in early 2012, VIBATIV® was returned to us, and we have no experience selling or distributing products and no internal capability to do so.

        Generally, our strategy is to engage pharmaceutical or other healthcare companies with an existing sales and marketing organization and distribution system to market, sell and distribute our products. We may not be able to establish these sales and distribution relationships on acceptable terms, or at all. With VIBATIV®, which was returned to us by Astellas in January 2012, and any of our product candidates that receive regulatory approval in the future and are not covered by our current agreements with GSK or AstraZeneca, we will need a partner in order to commercialize such products unless we establish a sales and marketing organization with appropriate technical expertise and supporting infrastructure and distribution capability. At present, we have no sales personnel and a

17


Table of Contents

limited number of marketing personnel. Factors that may inhibit our efforts to commercialize our products without strategic partners or licensees include:

        If we are not able to partner with a third party and are not successful in recruiting sales and marketing personnel or in building a sales and marketing organization with appropriate technical expertise and supporting infrastructure and distribution capability, we will have difficulty commercializing VIBATIV® and other product candidates, which would adversely affect our business and financial condition and which could cause the price of our securities to fall.

With regard to all of our programs, any delay in commencing or completing clinical studies for product candidates and any adverse results from clinical or non-clinical studies or regulatory obstacles product candidates may face, would harm our business and could cause the price of our securities to fall.

        Each of our product candidates must undergo extensive non-clinical and clinical studies as a condition to regulatory approval. Non-clinical and clinical studies are expensive, take many years to complete and study results may lead to delays in further studies or decisions to terminate programs. For example, we had planned to commence the Phase 2b study in our MABA program with GSK in 2009, but the program was delayed until late 2010.

        The commencement and completion of clinical studies for our product candidates may be delayed and programs may be terminated due to many factors, including, but not limited to:

18


Table of Contents

If our product candidates that we develop on our own or through collaborative partners are not approved by regulatory authorities, including the FDA, we will be unable to commercialize them.

        The FDA must approve any new medicine before it can be marketed and sold in the United States. We must provide the FDA and similar foreign regulatory authorities with data from preclinical and clinical studies that demonstrate that our product candidates are safe and effective for a defined indication before they can be approved for commercial distribution. We will not obtain this approval for a product candidate unless and until the FDA approves a NDA. The processes by which regulatory approvals are obtained from the FDA to market and sell a new product are complex, require a number of years and involve the expenditure of substantial resources. In order to market our medicines in foreign jurisdictions, we must obtain separate regulatory approvals in each country. The approval procedure varies among countries and can involve additional testing, and the time required to obtain approval may differ from that required to obtain FDA approval. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or by the FDA. Conversely, failure to obtain approval in one or more jurisdictions may make approval in other jurisdictions more difficult.

        Clinical studies involving our product candidates may reveal that those candidates are ineffective, inferior to existing approved medicines, unacceptably toxic, or that they have other unacceptable side effects. In addition, the results of preclinical studies do not necessarily predict clinical success, and larger and later-stage clinical studies may not produce the same results as earlier-stage clinical studies.

        Frequently, product candidates that have shown promising results in early preclinical or clinical studies have subsequently suffered significant setbacks or failed in later clinical studies. In addition, clinical studies of potential products often reveal that it is not possible or practical to continue development efforts for these product candidates. If our clinical studies are substantially delayed or fail to prove the safety and effectiveness of our product candidates in development, we may not receive regulatory approval of any of these product candidates and our business and financial condition will be materially harmed and the price of our securities may fall.

If telavancin is not approved for nosocomial pneumonia (NP) in the United States, the commercialization of VIBATIV® in the U.S. will continue to be adversely affected and the price of our securities could fall.

        Our first New Drug Application (NDA), for VIBATIV® (telavancin) for the treatment of complicated skin and skin structure infections (cSSSI) caused by susceptible Gram-positive bacteria in adult patients, was approved by the FDA in September 2009. In January 2009, we submitted a second telavancin NDA to the FDA for the NP indication based on data from our two Phase 3 studies referred to as the ATTAIN studies. These studies were conducted in accordance with the then current draft FDA guidelines and met their primary efficacy endpoint of clinical cure. During the fourth quarter of 2010 the FDA issued new draft guidance for antibacterial clinical trial design for the treatment of NP with a focus on mortality as the primary efficacy endpoint. In late 2010, we received a Complete Response Letter from the FDA indicating that the ATTAIN studies do not meet the new draft guidance and that additional clinical studies will be required for approval. We do not plan to conduct additional clinical studies for NP, but we do intend to continue to engage with FDA concerning the NP

19


Table of Contents

NDA. Lack of FDA approval for use of telavancin to treat NP has adversely affected and may continue to adversely affect commercialization of this medicine in the United States.

If any product candidates, in particular those in any respiratory program with GSK, are determined to be unsafe or ineffective in humans, our business will be adversely affected and the price of our securities could fall.

        Although our first product, VIBATIV®, is approved in the U.S. and Canada, none of our other product candidates have been approved by regulatory authorities. We are uncertain whether any of our other product candidates will prove effective and safe in humans or meet applicable regulatory standards. In addition, our approach to applying our expertise in multivalency to drug discovery may not result in the creation of successful medicines. The risk of failure for our product candidates is high. For example, in late 2005, we discontinued our overactive bladder program based upon the results of our Phase 1 studies with compound TD-6301, and GSK discontinued development of TD-5742, the first LAMA compound licensed from us, after completing a single-dose Phase 1 study. The data supporting our drug discovery and development programs is derived solely from laboratory experiments, non-clinical studies and clinical studies. A number of other compounds remain in the lead identification, lead optimization, preclinical testing or early clinical testing stages.

        Several well-publicized Complete Response letters issued by the FDA and safety-related product withdrawals, suspensions, post-approval labeling revisions to include boxed warnings and changes in approved indications over the last several years, as well as growing public and governmental scrutiny of safety issues, have created an increasingly conservative regulatory environment. The implementation of new laws and regulations, and revisions to FDA clinical trial design guidance, have increased uncertainty regarding the approvability of a new drug. Further, there are additional requirements for approval of new drugs, including advisory committee meetings for new chemical entities, and formal risk evaluation and mitigation strategy (REMS) at the FDA's discretion. These new laws, regulations, additional requirements and changes in interpretation could cause non-approval or further delays in the FDA's review and approval of our product candidates.

There is currently a single manufacturer for VIBATIV® product supply and we rely on a single source of supply for a number of our product candidates; accordingly, our business will be harmed if these manufacturers are not able to satisfy demand and alternative sources are not available.

        There is currently a single source of supply of telavancin API and a single source of supply of VIBATIV® drug product. If, for any reason, these third parties are unable or unwilling to perform, or if their performance does not meet regulatory requirements, including maintaining current good manufacturing practice (cGMP) compliance, we may not be able to locate alternative manufacturers, enter into acceptable agreements with them or obtain sufficient quantities of API and drug product in a timely manner. Any inability to acquire sufficient quantities of API and drug product in a timely manner from current or future sources could further adversely affect the commercialization of VIBATIV® and could cause the price of our securities to fall.

        During the fourth quarter of 2011, the third party manufacturer of VIBATIV® drug product notified the FDA of an ongoing investigation related to its production equipment and processes. The notification included all products manufactured at the third party manufacturer's facility which remain within expiry, including batches of manufactured but unreleased VIBATIV®. In November 2011, Astellas (our former VIBATIV® collaboration partner) voluntarily placed a hold on distribution of VIBATIV® to wholesalers, and cancelled pending orders for VIBATIV® with this manufacturer. VIBATIV® drug product previously manufactured by, and still on-site at, this manufacturer will not become available for sale in the U.S. unless and until the batches are released. We cannot predict when or if the manufactured batches of VIBATIV® will be released. In addition, in August 2011 the third party manufacturer of VIBATIV® drug product announced its intention to transition out of the

20


Table of Contents

contract manufacturing services business over the next several years. Additional VIBATIV® drug product will need to be manufactured to meet longer-term U.S. demand as well as demand from the E.U. and Canada. In February 2012 the Committee for Medicinal Products for Human Use (CHMP) recommended to the European Commission that it suspend marketing authorization for VIBATIV® because the single-source VIBATIV® drug product supplier does not meet the GMP requirements to allow the manufacture of VIBATIV®. No VIBATIV® drug product intended to meet E.U. specifications has as yet been manufactured. Identifying and qualifying an alternative manufacturer for VIBATIV® drug product may take 12 to 24 months.

        If the VIBATIV® drug product on-site at the third party manufacturer is not released in the near future, the commercialization of VIBATIV® in the U.S. will continue to be adversely affected, and if supplemental or alternative commercial manufacture of VIBATIV® drug product cannot be arranged on a timely basis, the commercial introduction of VIBATIV® in the E.U. and Canada will be materially delayed. In each such case, our business will be harmed and the price of our securities could fall.

        With respect to our programs other than VIBATIV®, we have limited in-house production capabilities for non-clinical and early clinical study purposes, and depend primarily on a number of third-party API and drug product manufacturers. We may not have long-term agreements with these third parties and our agreements with these parties may be terminable at will by either party at any time. If, for any reason, these third parties are unable or unwilling to perform, or if their performance does not meet regulatory requirements, we may not be able to locate alternative manufacturers or enter into acceptable agreements with them. Any inability to acquire sufficient quantities of API and drug product in a timely manner from these third parties could delay clinical studies, prevent us from developing our product candidates in a cost-effective manner or on a timely basis. In addition, manufacturers of our API and drug product are subject to the FDA's cGMP regulations and similar foreign standards and we do not have control over compliance with these regulations by our manufacturers.

        Our manufacturing strategy presents the following additional risks:

Even if our product candidates receive regulatory approval, as VIBATIV® has, commercialization of such products may be adversely affected by regulatory actions and oversight.

        Even if we receive regulatory approval for our product candidates, this approval may include limitations on the indicated uses for which we can market our medicines or the patient population that may utilize our medicines, which may limit the market for our medicines or put us at a competitive disadvantage relative to alternative therapies. For example, VIBATIV®'s U.S. labeling contains a boxed

21


Table of Contents

warning regarding the risks of use of VIBATIV® during pregnancy. Products with boxed warnings are subject to more restrictive advertising regulations than products without such warnings. In addition, the VIBATIV® labeling that was approved for the E.U. in 2011 specifies that VIBATIV® should be used only in situations where it is known or suspected that other alternatives are not suitable. These restrictions could make it more difficult to market VIBATIV®. Further, in February 2012 the CHMP recommended to the European Commission that it suspend marketing authorization for VIBATIV® because the single-source VIBATIV® drug product supplier does not meet the GMP requirements to allow the manufacture of VIBATIV®. With VIBATIV® approved in certain countries, we are subject to continuing regulatory obligations, such as safety reporting requirements and additional post-marketing obligations, including regulatory oversight of promotion and marketing.

        In addition, the manufacturing, labeling, packaging, adverse event reporting, advertising, promotion and recordkeeping for the approved product remain subject to extensive and ongoing regulatory requirements. If we become aware of previously unknown problems with an approved product in the U.S. or overseas or at contract manufacturers' facilities, a regulatory authority may impose restrictions on the product, the contract manufacturers or on us, including requiring us to reformulate the product, conduct additional clinical studies, change the labeling of the product, withdraw the product from the market or require the contract manufacturer to implement changes to its facilities. For example, during the fourth quarter of 2011, the third party manufacturer of VIBATIV® drug product notified the FDA of an ongoing investigation related to its production equipment and processes. The notification included all products manufactured at the third party manufacturer's facility which remain within expiry, including batches of manufactured but unreleased VIBATIV®. Astellas (our former VIBATIV® collaboration partner) subsequently placed a voluntary hold on distribution of VIBATIV® to wholesalers and cancelled pending orders for VIBATIV® with this manufacturer. With this supply interruption and the termination of our VIBATIV® collaboration agreement with Astellas, commercialization of VIBATIV® has essentially stopped, we will likely experience a significant drop in the sales of the product and the reputation of VIBATIV® in the marketplace may suffer.

        We are also subject to regulation by regional, national, state and local agencies, including the Department of Justice, the Federal Trade Commission, the Office of Inspector General of the U.S. Department of Health and Human Services and other regulatory bodies with respect to VIBATIV®, as well as governmental authorities in those foreign countries in which any of our product candidates are approved for commercialization. The Federal Food, Drug, and Cosmetic Act, the Public Health Service Act and other federal and state statutes and regulations govern to varying degrees the research, development, manufacturing and commercial activities relating to prescription pharmaceutical products, including non-clinical and clinical testing, approval, production, labeling, sale, distribution, import, export, post-market surveillance, advertising, dissemination of information and promotion. If we or any third parties that provide these services for us are unable to comply, we may be subject to regulatory or civil actions or penalties that could significantly and adversely affect our business. Any failure to maintain regulatory approval will limit our ability to commercialize our product candidates, which would materially and adversely affect our business and financial condition, which may cause our stock price to decline.

We have incurred operating losses in each year since our inception and expect to continue to incur substantial losses for the foreseeable future.

        We have been engaged in discovering and developing compounds and product candidates since mid-1997. Our first approved product, VIBATIV®, was launched by our partner Astellas in the U.S. in November 2009, and to date we have received only modest revenues from VIBATIV® sales. We may never generate sufficient revenue from the sale of medicines or royalties on sales by our partners to achieve profitability. As of December 31, 2011, we had an accumulated deficit of approximately $1.3 billion.

        We expect to incur substantial expenses as we continue our drug discovery and development efforts, particularly to the extent we advance our product candidates into and through clinical studies, which are very expensive. As a result, we expect to continue to incur substantial losses for the foreseeable future. We are uncertain when or if we will be able to achieve or sustain profitability. Failure to become and remain profitable would adversely affect the price of our securities and our ability to raise capital and continue operations.

If we fail to obtain the capital necessary to fund our operations, we may be unable to develop our product candidates or commercialize VIBATIV® and we could be forced to share our rights to commercialize our product candidates with third parties on terms that may not be favorable to us.

        We need large amounts of capital to support our research and development efforts. If we are unable to secure capital to fund our operations we will not be able to continue our discovery and development efforts and we might have to enter into strategic collaborations that could require us to share commercial rights to our medicines to a greater extent than we currently intend. Based on our current operating plans, milestone and royalty forecasts and spending assumptions, we believe that our cash and cash equivalents and marketable securities will be sufficient to meet our anticipated operating needs for at least the next twelve months. We are likely to require additional capital to fund operating needs thereafter. Although we have no current intention to do so, if we were to conduct additional studies to support the telavancin NP NDA, or if we were to build the sales and marketing, distribution and compliance infrastructure to commercialize VIBATIV® without a partner, our capital needs would increase substantially. We intend to continue development of our pipeline. A Phase 2b program is underway in our PµMA program and we initiated a Phase 2 study for MARIN in late 2011. We also intend to invest in other assets in our pipeline, including our Hepatitis C virus (HCV) and cardiovascular programs in late-stage discovery, and conduct a number of other non-clinical and earlier-stage clinical studies in other programs. Further, pursuant to the terms of the recent termination of our collaboration agreement with Astellas, we may purchase up to $11.0 million of VIBATIV® inventory during 2012. In addition, under our LABA collaboration with GSK, in the event that vilanterol (VI), which is the current lead LABA product candidate in RELOVAIR™ and LAMA/LABA ('719/VI) and which was discovered by GSK, is approved and launched in multiple regions of the world as both a single agent and a combination product or two different combination products, we will be obligated to pay GSK milestone payments that could total as much as $220.0 million and we would not be entitled to receive any further milestone payments from GSK. Future financing to meet our capital needs may not be available in sufficient amounts or on terms acceptable to us, if at all. Even if we are able to raise additional capital, such financing may result in significant dilution to existing security holders. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to make reductions in our workforce and may be prevented from continuing our discovery and development efforts and exploiting other corporate opportunities. This could harm our business, prospects and financial condition and cause the price of our securities to fall.

VIBATIV® may not be accepted by physicians, patients, third party payors, or the medical community in general, and this risk is aggravated by the current critical product shortages and regional supply outages.

        The commercial success of VIBATIV® depends upon its acceptance by physicians, patients, third party payors and the medical community in general. We cannot be sure that VIBATIV® will be accepted by these parties. VIBATIV® competes with vancomycin, a relatively inexpensive generic drug that is manufactured by a variety of companies, and a number of existing antibacterials manufactured and marketed by major pharmaceutical companies and others, and may compete against new antibacterials that are not yet on the market. Even if the medical community accepts that VIBATIV® is safe and efficacious for its indicated use, physicians may restrict the use of VIBATIV® due to the current product shortages stemming from the manufacturing issues at the drug product supplier, the recent termination of our VIBATIV® collaboration agreement with Astellas, or otherwise. If we are

23


Table of Contents

unable to demonstrate to physicians that, based on experience, clinical data, side-effect profiles and other factors, VIBATIV® is preferable to vancomycin and other antibacterial drugs, we may never generate meaningful revenue from VIBATIV® which could cause the price of our securities to fall. The degree of market acceptance of VIBATIV® depends on a number of factors, including, but not limited to:

If our partners do not satisfy their obligations under our agreements with them, or if they terminate our partnerships with them, as Astellas did with our VIBATIV® collaboration agreement in January 2012, we may not be able to develop or commercialize our partnered product candidates as planned.

        We entered into our LABA collaboration agreement with GSK in November 2002, our strategic alliance agreement with GSK in March 2004, and our VIBATIV® collaboration agreement with Astellas in November 2005. In connection with these agreements, we have granted to these parties certain rights regarding the use of our patents and technology with respect to compounds in our development programs, including development and marketing rights. Under our GSK agreements, GSK has full responsibility for development and commercialization of RELOVAIR™, LAMA/LABA ('719/VI) and any product candidates in the MABA program. Any future milestone payments or royalties to us from these programs will depend on the extent to which GSK advances the product candidate through development and, if approved, commercialization. Astellas terminated the VIBATIV® agreement in January 2012.

        Our partners might not fulfill all of their obligations under these agreements, and, in certain circumstances, they may terminate our partnership with them, as Astellas did in January 2012. In either event, we may be unable to assume the development and commercialization of the product candidates covered by the agreements or enter into alternative arrangements with a third party to develop and commercialize such product candidates. In addition, with the exception of product candidates in our LABA collaboration and the MABA program under the strategic alliance, our partners generally are not restricted from developing and commercializing their own products and product candidates that compete with those licensed from us. If a partner elected to promote its own products and product candidates in preference to those licensed from us, future payments to us could be reduced and our business and financial condition would be materially and adversely affected. Accordingly, our ability to receive any revenue from the product candidates covered by these agreements is dependent on the efforts of the partner. We could also become involved in disputes with a partner, which could lead to

24


Table of Contents

delays in or termination of our development and commercialization programs and time-consuming and expensive litigation or arbitration.

        If a partner terminates or breaches its agreements with us, or otherwise fails to complete its obligations in a timely manner, the chances of successfully developing or commercializing product candidates under the collaboration could be materially and adversely affected. For example, Astellas terminated the VIBATIV® collaboration agreement in January 2012, and both due to the termination and the current product shortages and regional supply outages stemming from the manufacturing issues at the third party VIBATIV® drug product supplier, the commercialization of VIBATIV® in the U.S. has essentially stopped and the commercial introduction of VIBATIV® in the E.U. and Canada has been delayed.

If we are unable to enter into future collaboration arrangements or if any such collaborations with third parties are unsuccessful, we will be unable to fully develop and commercialize VIBATIV® and our product candidates and our business will be adversely affected.

        We have active collaborations with GSK for RELOVAIR™, LAMA/LABA ('719/VI) and the MABA program and we have licensed our anesthesia compound to AstraZeneca AB (AstraZeneca). Additional collaborations will be needed to fund later-stage development of our product candidates that have not been licensed to a collaborator, and to commercialize these product candidates if approved by the necessary regulatory authorities. Each of TD-5108, our lead compound in the 5-HT4 program, TD-1792, our investigational antibiotic, TD-1211, the lead compound in our PµMA program for opioid-induced constipation and TD-4208, our LAMA compound, has successfully completed a Phase 2 proof-of-concept study. In addition, in connection with the expansion of the MABA program under the strategic alliance with GSK in October 2011, GSK relinquished its right to option our MARIN and ARNI programs. Also, we now have full rights to VIBATIV® as a result of the termination of our collaboration agreement with Astellas in January 2012. We currently intend to seek third parties with which to pursue collaboration arrangements for the development and commercialization of our development programs and for the future commercialization of VIBATIV®. Collaborations with third parties regarding these programs or our other programs may require us to relinquish material rights, including revenue from commercialization of our medicines, on terms that are less attractive than our current arrangements or to assume material ongoing development obligations that we would have to fund. These collaboration arrangements are complex and time-consuming to negotiate, and if we are unable to reach agreements with third-party collaborators, we may fail to meet our business objectives and our financial condition may be adversely affected. We face significant competition in seeking third-party collaborators, especially in the current uncertain economy, which is driving many biotechnology and biopharmaceutical companies to seek to sell or license their assets. We may be unable to find third parties to pursue product collaborations on a timely basis or on acceptable terms. Furthermore, for any collaboration, we may not be able to control the amount of time and resources that our partners devote to our product candidates and our partners may choose to pursue alternative products. Our inability to successfully collaborate with third parties would increase our development costs and would limit the likelihood of successful commercialization of our product candidates which may cause our stock price to decline.

We depend on third parties in the conduct of our clinical studies for our product candidates.

        We depend on independent clinical investigators, contract research organizations and other third-party service providers in the conduct of our non-clinical and clinical studies for our product candidates. We rely heavily on these parties for execution of our non-clinical and clinical studies, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that our clinical studies are conducted in accordance with good clinical practices (GCPs) and other regulations as required by the FDA and foreign regulatory authorities, and the applicable protocol. Failure by these

25


Table of Contents

parties to comply with applicable regulations, GCPs and protocols in conducting studies of our product candidates can result in a delay in our development programs or non-approval of our product candidates by regulatory authorities.

        The FDA enforces good clinical practices and other regulations through periodic inspections of trial sponsors, clinical research organizations (CROs), principal investigators and trial sites. For example, in connection with the FDA's review of our telavancin NDAs, the FDA conducted inspections of Theravance and certain of our study sites, clinical investigators and CROs. If we or any of the third parties on which we have relied to conduct our clinical studies are determined to have failed to comply with GCPs, the study protocol or applicable regulations, the clinical data generated in our studies may be deemed unreliable. This could result in non-approval of our product candidates by the FDA, or we or the FDA may decide to conduct additional audits or require additional clinical studies, which would delay our development programs, could result in significant additional costs and could cause the price of our securities to fall.

We face substantial competition from companies with more resources and experience than we have, which may result in others discovering, developing, receiving approval for or commercializing products before or more successfully than we do.

        Our ability to succeed in the future depends on our ability to demonstrate and maintain a competitive advantage with respect to our approach to the discovery and development of medicines. Our objective is to discover, develop and commercialize new small molecule medicines with superior efficacy, convenience, tolerability and/or safety. We expect that any medicines that we commercialize with our collaborative partners will compete with existing or future market-leading medicines.

        Many of our potential competitors have substantially greater financial, technical and personnel resources than we have. In addition, many of these competitors have significantly greater commercial infrastructures than we have. Our ability to compete successfully will depend largely on our ability to leverage our experience in drug discovery and development to:

        Established pharmaceutical companies may invest heavily to quickly discover and develop or in-license novel compounds that could make our product candidates obsolete. Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA approval or discovering, developing and commercializing medicines before we do. Other companies are engaged in the discovery of medicines that would compete with the product candidates that we are developing.

        Any new medicine that competes with a generic or proprietary market leading medicine must demonstrate compelling advantages in efficacy, convenience, tolerability and/or safety in order to overcome severe price competition and be commercially successful. VIBATIV® must demonstrate these advantages, as it competes with vancomycin, a relatively inexpensive generic drug that is manufactured by a number of companies, and a number of existing antibacterial drugs marketed by major and other pharmaceutical companies. If we are not able to compete effectively against our current and future competitors, our business will not grow, our financial condition and operations will suffer and the price of our securities could fall.

26


Table of Contents

        As the principles of multivalency become more widely known, we expect to face increasing competition from companies and other organizations that pursue the same or similar approaches. Novel therapies, such as gene therapy or effective vaccines for infectious diseases, may emerge that will make both conventional and multivalent medicine discovery efforts obsolete or less competitive.

If we lose key management or scientific personnel, or if we fail to retain our key employees, our ability to discover and develop our product candidates will be impaired.

        We are highly dependent on principal members of our management team and scientific staff to operate our business. Our company is located in northern California, which is headquarters to many other biotechnology and biopharmaceutical companies and many academic and research institutions. As a result, competition for certain skilled personnel in our market remains intense. None of our employees have employment commitments for any fixed period of time and they all may leave our employment at will. If we fail to retain our qualified personnel or replace them when they leave, we may be unable to continue our development and commercialization activities, which may cause our stock price to decline.

Our business and operations would suffer in the event of system failures.

        Although we have security measures in place, our internal computer systems and those of our CROs and other service providers are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. We have not experienced any material system failure, accident or security breach to date, but if such an event were to occur, it could result in a material disruption to our business. For example, the loss of clinical trial data from completed or ongoing clinical trials of our product candidates could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. If a disruption or security breach results in a loss of or damage to our data or regulatory applications, or inadvertent disclosure of confidential or proprietary information, we could incur liability, the further development of our product candidates could be delayed and the price of our securities could fall.

Our principal facility is located near known earthquake fault zones, and the occurrence of an earthquake, extremist attack or other catastrophic disaster could cause damage to our facilities and equipment, which could require us to cease or curtail operations.

        Our principal facility is located in the San Francisco Bay Area near known earthquake fault zones and therefore is vulnerable to damage from earthquakes. In October 1989, a major earthquake struck this area and caused significant property damage and a number of fatalities. We are also vulnerable to damage from other types of disasters, including power loss, attacks from extremist organizations, fire, floods, communications failures and similar events. If any disaster were to occur, our ability to operate our business could be seriously impaired. In addition, the unique nature of our research activities and of much of our equipment could make it difficult for us to recover from this type of disaster. We may not have adequate insurance to cover our losses resulting from disasters or other similar significant business interruptions and we do not plan to purchase additional insurance to cover such losses due to the cost of obtaining such coverage. Any significant losses that are not recoverable under our insurance policies could seriously impair our business and financial condition, which could cause the price of our securities to fall.

Risks Related to our Alliance with GSK

GSK's ownership of a significant percentage of our stock and its ability to acquire additional shares of our stock may create conflicts of interest, and may inhibit our management's ability to continue to operate our business in the manner in which it is currently being operated.

        As of February 17, 2012, GSK beneficially owned approximately 18.4% of our outstanding capital stock, and GSK has the right to acquire stock from us to maintain its percentage ownership of our capital stock. GSK could have substantial influence in the election of our directors, delay or prevent a transaction in which stockholders might receive a premium over the prevailing market price for their shares and have significant control over certain changes in our business.

        In addition, GSK may make an offer to our stockholders to acquire outstanding voting stock that would bring GSK's percentage ownership of our voting stock to no greater than 60%, provided that:

        If pursuant to the provision described above GSK's ownership of us becomes greater than 50.1%, then on or prior to September 1, 2012 GSK is allowed to make an offer to our stockholders to merge with us or otherwise acquire outstanding voting stock that would bring GSK's percentage ownership of our voting stock to 100%, provided that;

        Furthermore, if pursuant to the provision described above GSK's ownership of us is greater than 50.1%, then after September 1, 2012, GSK is allowed to make an offer to our stockholders to acquire outstanding voting stock that would bring GSK's percentage ownership of our voting stock to 100%, provided that;

        Further, pursuant to our certificate of incorporation, we renounce our interest in and waive any claim that a corporate or business opportunity taken by GSK constitutes a corporate opportunity of ours unless such corporate or business opportunity is expressly offered to one of our directors who is a director, officer or employee of GSK, primarily in his or her capacity as one of our directors.

28


Table of Contents

GSK's rights under the governance agreement may deter or prevent efforts by other companies to acquire us, which could prevent our stockholders from realizing a control premium.

        Our governance agreement with GSK requires us to exempt GSK from our stockholder rights plan, affords GSK certain rights to offer to acquire us in the event third parties seek to acquire our stock and contains other provisions that could deter or prevent another company from seeking to acquire us. For example, GSK may offer to acquire 100% of our outstanding stock from stockholders in certain circumstances, such as if we are faced with a hostile acquisition offer or if our board of directors acts in a manner to facilitate a change in control of us with a party other than GSK. As a result of these rights, other companies may be less inclined to pursue an acquisition of us and therefore we may not have the opportunity to be acquired in a transaction that stockholders might otherwise deem favorable, including transactions in which our stockholders might realize a substantial premium for their shares.

GSK could sell or transfer a substantial number of shares of our common stock, which could depress the price of our securities or result in a change in control of our company.

        Under our governance agreement with GSK, GSK currently may sell or transfer our common stock only pursuant to a public offering registered under the Securities Act or pursuant to Rule 144 of the Securities Act. Beginning in September 2012, GSK will have no contractual restrictions on its ability to sell or transfer our common stock on the open market, in privately negotiated transactions or otherwise, and these sales or transfers could create substantial declines in the price of our securities or, if these sales or transfers were made to a single buyer or group of buyers, could contribute to a transfer of control of our company to a third party.

Risks Related to Legal and Regulatory Uncertainty

If our efforts to protect the proprietary nature of the intellectual property related to our technologies are not adequate, we may not be able to compete effectively in our market.

        We rely upon a combination of patents, patent applications, trade secret protection and confidentiality agreements to protect the intellectual property related to our technologies. Any involuntary disclosure to or misappropriation by third parties of this proprietary information could enable competitors to quickly duplicate or surpass our technological achievements, thus eroding our competitive position in our market. The status of patents in the biotechnology and pharmaceutical field involves complex legal and scientific questions and is very uncertain. As of December 31, 2011, we owned 271 issued United States patents and 907 granted foreign patents, as well as additional pending United States and foreign patent applications. Our patent applications may be challenged or fail to result in issued patents and our existing or future patents may be invalidated or be too narrow to prevent third parties from developing or designing around these patents. If the sufficiency of the breadth or strength of protection provided by our patents with respect to a product candidate is threatened, it could dissuade companies from collaborating with us to develop, and threaten our ability to commercialize, the product candidate. Further, if we encounter delays in our clinical trials or in obtaining regulatory approval of our product candidates, the patent lives of the related product candidates would be reduced.

        In addition, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable, for processes for which patents are difficult to enforce and for any other elements of our drug discovery and development processes that involve proprietary know-how, information and technology that is not covered by patent applications. Although we require our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information and technology to enter into confidentiality agreements, we cannot be certain that this know-how, information and technology will not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information

29


Table of Contents

and techniques. Further, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent material disclosure of the intellectual property related to our technologies to third parties, we will not be able to establish or, if established, maintain a competitive advantage in our market, which could materially adversely affect our business, financial condition and results of operations, which could cause the price of our securities to fall.

Litigation or third-party claims of intellectual property infringement would require us to divert resources and may prevent or delay our drug discovery and development efforts.

        Our commercial success depends in part on us and our partners not infringing the patents and proprietary rights of third parties. Third parties may assert that we or our partners are using their proprietary rights without authorization. There are third party patents that may cover materials or methods for treatment related to our product candidates. At present, we are not aware of any patent claims with merit that would adversely and materially affect our ability to develop our product candidates, but nevertheless the possibility of third party allegations cannot be ruled out. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Furthermore, parties making claims against us or our partners may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business.

        In the event of a successful claim of infringement against us, we may have to pay substantial damages, obtain one or more licenses from third parties or pay royalties. In addition, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could harm our business significantly. In addition, in the future we could be required to initiate litigation to enforce our proprietary rights against infringement by third parties. Prosecution of these claims to enforce our rights against others would involve substantial litigation expenses and divert substantial employee resources from our business. If we fail to effectively enforce our proprietary rights against others, our business will be harmed, which may cause our stock price to decline.

If the efforts of our partner, GSK, to protect the proprietary nature of the intellectual property related to the assets in the LABA collaboration, including RELOVAIR™ and LAMA/LABA ('719/VI), are not adequate, the future commercialization of any medicines resulting from the LABA collaboration could be delayed or prevented, which would materially harm our business and could cause the price of our securities to fall.

        The risks identified in the two preceding risk factors also apply to the intellectual property protection efforts of our partner, GSK. To the extent the intellectual property protection of any of the assets in the LABA collaboration are successfully challenged or encounter problems with the United States Patent and Trademark Office or other comparable agencies throughout the world, the future commercialization of these potential medicines could be delayed or prevented. Any challenge to the intellectual property protection of a late-stage development asset arising from the LABA collaboration could harm our business and cause the price of our securities to fall.

Table of Contents

Product liability lawsuits could divert our resources, result in substantial liabilities and reduce the commercial potential of our medicines.

        The risk that we may be sued on product liability claims is inherent in the development and commercialization of pharmaceutical products. Side effects of, or manufacturing defects in, products that we or our partners develop or commercialize could result in the deterioration of a patient's condition, injury or even death. Once a product is approved for sale and commercialized, the likelihood of product liability lawsuits tends to increase. Claims may be brought by individuals seeking relief for themselves or by individuals or groups seeking to represent a class. These lawsuits may divert our management from pursuing our business strategy and may be costly to defend. In addition, if we are held liable in any of these lawsuits, we may incur substantial liabilities and may be forced to limit or forgo further commercialization of the applicable products.

        Although we maintain general liability and product liability insurance, this insurance may not fully cover potential liabilities. In addition, inability to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims could prevent or inhibit the commercial production and sale of our products, which could adversely affect our business. Product liability claims could also harm our reputation, which may adversely affect our and our partners' ability to commercialize our products successfully, which could cause the price of our securities to fall.

Government restrictions on pricing and reimbursement, as well as other healthcare payor cost-containment initiatives, may negatively impact our ability to generate revenues.

        The continuing efforts of the government, insurance companies, managed care organizations and other payors of health care costs to contain or reduce costs of health care may adversely affect one or more of the following:

        The Patient Protection and Affordable Care Act and other potential legislative or regulatory action regarding healthcare and insurance matters, along with the trend toward managed healthcare in the United States, could influence the purchase of healthcare products and reduce demand and prices for our products, if approved. This could harm our or our collaborators' ability to market our potential medicines and generate revenues. Cost containment measures that health care payors and providers are instituting and the effect of the Patient Protection and Affordable Care Act and further agency regulations that are likely to emerge in connection with the passage of this act could significantly reduce potential revenues from the sale of any product candidates approved in the future. In addition, in certain foreign markets, the pricing of prescription drugs is subject to government control and reimbursement may in some cases be unavailable. We believe that pricing pressures at the state and federal level, as well as internationally, will continue and may increase, which may make it difficult for us to sell our potential medicines that may be approved in the future at a price acceptable to us or our collaborators, which may cause our stock price to decline.

If we use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be liable for damages.

        Our research and development activities involve the controlled use of potentially hazardous substances, including chemical, biological and radioactive materials. In addition, our operations produce hazardous waste products. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of hazardous materials. We may incur significant additional costs to comply with these and other applicable laws in the future. Also, even if we are in compliance with

31


Table of Contents

applicable laws, we cannot completely eliminate the risk of contamination or injury resulting from hazardous materials and we may incur liability as a result of any such contamination or injury. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our resources. We do not have any insurance for liabilities arising from hazardous materials. Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development and production efforts, which could harm our business, which could cause the price of our securities to fall.

Risks Related to Ownership of our Common Stock

The price of our securities has been extremely volatile and may continue to be so, and purchasers of our securities could incur substantial losses.

        The price of our securities has been extremely volatile and may continue to be so. The stock market in general and the market for biotechnology and biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the companies' operating performance, in particular during the last few years. The following factors, in addition to the other risk factors described in this section, may also have a significant impact on the market price of our securities:

Concentration of ownership will limit your ability to influence corporate matters.

        As of February 17, 2012, GSK beneficially owned approximately 18.4% of our outstanding capital stock and our directors, executive officers and investors affiliated with these individuals beneficially owned approximately 6.58% of our outstanding capital stock. Based on our review of publicly available filings as of February 17, 2012, our six largest stockholders other than GSK collectively owned approximately 50.9% of our outstanding capital stock. These stockholders could control the outcome of actions taken by us that require stockholder approval, including a transaction in which stockholders might receive a premium over the prevailing market price for their shares.

Anti-takeover provisions in our charter and bylaws, in our rights agreement and in Delaware law could prevent or delay a change in control of our company.

        Provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions include:

        In addition, our board of directors has adopted a rights agreement that may prevent or delay a change in control of us. Further, some provisions of Delaware law may also discourage, delay or prevent someone from acquiring us or merging with us.

Executive Summary

        Theravance is a biopharmaceutical company with a pipeline of internally discovered product candidates and strategic collaborations with pharmaceutical companies. We are focused on the discovery, development and commercialization of small molecule medicines across a number of therapeutic areas including respiratory disease, bacterial infections, and central nervous system (CNS)/pain. Our key programs include: RELOVAIR™, LAMA/LABA ('719/vilanterol (VI)) and MABA (Bifunctional Muscarinic Antagonist-Beta2 Agonist), each partnered with GlaxoSmithKline plc (GSK), and our oral Peripheral Mu Opioid Receptor Antagonist (PµMA) program. By leveraging our proprietary insight of multivalency to drug discovery, we are pursuing a best-in-class strategy designed to discover superior medicines in areas of significant unmet medical need.

        Our net loss for the year ended December 31, 2011 was $115.3 million compared to $83.9 million in 2010. This increase was due primarily to higher research and development expenses. Research and development expenses for the year ended December 31, 2011 increased to $103.5 million compared to $75.1 million in 2010. This increase was driven primarily by higher external costs. Cash, cash equivalents, and short-term investments totaled $240.9 million at December 31, 2011, a decrease of $68.7 million since December 31, 2010. The decrease was due primarily to cash used in operations,

partially offset by net proceeds of $13.6 million received from sales of our common stock to an affiliate of GSK, net proceeds of $10.1 million received from exercises of employee stock options, a $3.0 million milestone payment received from GSK for the initiation of a Phase 1 combination study in the MABA program, a $1.0 million upfront license payment related to GSK's license of additional preclinical MABA compounds from us, and $2.4 million royalty revenue from VIBATIV® sales.

Program Highlights

Respiratory Programs with GSK

RELOVAIR™

        RELOVAIR™ is an investigational once-daily inhaled corticosteroid (ICS)/long-acting beta2 agonist (LABA) combination treatment, comprising fluticasone furoate and vilanterol (FF/VI), currently in development for the treatment of patients with chronic obstructive pulmonary disease (COPD) or asthma.

        In January 2012, we and GSK announced that GSK intends to commence global regulatory filings in COPD and asthma beginning in mid-2012 based upon the initial outcomes from pivotal Phase 3 studies for once-daily RELOVAIR™ in COPD and asthma. For asthma, GSK will continue discussions with the U.S. Food and Drug Administration (FDA) on the regulatory requirements for a U.S. asthma indication.

LAMA/LABA Combination (GSK573719/Vilanterol or '719/VI)

        Enrollment is complete for the seven ongoing studies in the Phase 3 program for the once-daily long-acting muscarinic antagonist (LAMA)/LABA dual bronchodilator '719/VI. '719/VI combines two bronchodilators currently under development—'719, a LAMA and VI, a LABA. These two molecules provide two mechanisms of bronchodilation for patients with COPD: antagonism of acetylcholine muscarinic receptors and agonism of beta2 adrenoreceptors.

        The LAMA/LABA Phase 3 program, which will evaluate over 5,000 patients with COPD globally, consists of a 52-week study to evaluate the long term safety and tolerability of '719 (125mcg) alone, as well as the combination '719/VI (125/25mcg), two large 6-month pivotal studies that will compare improvements in lung function between '719/VI, its components and placebo, two 6-month studies to compare the combination with its components and tiotropium and two studies to assess the effect of '719/VI on exercise endurance. The Phase 3 program will investigate two doses of '719 (125mcg and 62.5mcg) and two doses of the combination '719/VI (125/25mcg and 62.5/25mcg).

Inhaled Bifunctional Muscarinic Antagonist-Beta2 Agonist (MABA)

        GSK961081 ('081), the lead compound in the MABA program with GSK, is a single molecule bifunctional bronchodilator with both muscarinic antagonist and beta2 receptor agonist activity. In February 2012, we announced topline results from a Phase 2b COPD study with '081.

        In October 2011, we and GSK amended the 2004 Strategic Alliance Agreement to expand the MABA program. We granted to GSK an exclusive license to develop and commercialize additional preclinical MABA compounds discovered by Theravance. We received an upfront license payment of $1.0 million and have the potential to receive clinical, regulatory and commercial milestone payments as well as royalties on worldwide net sales if one of these MABA compounds is successfully commercialized.

Bacterial Infections Program

VIBATIV® (telavancin) for injection

        In November 2005, we entered into a global collaboration arrangement with Astellas for the development and commercialization of VIBATIV®. On January 6, 2012, Astellas exercised its right to terminate this agreement. The rights granted to Astellas ceased upon termination of the agreement and Astellas has stopped promotional sales efforts. Pursuant to the terms of the agreement, there are no termination payments required by either party and Astellas is entitled to a ten-year, 2% royalty on future net sales of VIBATIV®. To support the transition, Astellas will sell inventory to us, manage certain clinical and regulatory activities and respond to medical inquiries with respect to VIBATIV® until no later than March 31, 2012. We currently are focusing our efforts on evaluating commercialization alternatives for VIBATIV®, including re-partnering, and re-establishing consistent VIBATIV® product supply.

        Due to manufacturing issues at the single-source supplier of VIBATIV® drug product, VIBATIV® is currently subject to critical product shortages and regional supply outages in the U.S., and the Committee for Medicinal Products for Human Use (CHMP) recommended to the European Commission that it suspend marketing authorization for VIBATIV®. If the issues at the manufacturer are not promptly resolved, obtaining supply would require identifying and qualifying an alternative manufacturer, which could take 12 to 24 months.

Central Nervous System (CNS)/Pain Program

Oral Peripheral Mu Opioid Receptor Antagonist (PµMA)—TD-1211

        Enrollment is progressing in the Phase 2b program, which will assess the safety, tolerability and clinical activity of TD-1211 in patients with opioid-induced constipation. This program is evaluating several doses and dose regimens to provide information for the design of the Phase 3 program. TD-1211 is an investigational once-daily, orally-administered, peripherally selective, multivalent inhibitor of the mu opioid receptor designed to alleviate gastrointestinal side effects of opioid therapy without affecting analgesia.

MonoAmine Reuptake INhibitor (MARIN)—TD-9855

        In December 2011, we announced the initiation of an Attention-Deficit/Hyperactivity Disorder (ADHD) Phase 2 proof-of-concept study with TD-9855, the lead compound in our MARIN program. This Phase 2 study will evaluate the safety and efficacy of two different doses of TD-9855 in adult male patients with ADHD. TD-9855 is an investigational norepinephrine and serotonin reuptake inhibitor (NSRI) discovered by Theravance for the treatment of CNS conditions such as ADHD and chronic pain.

Theravance Respiratory Program

Long-Acting Muscarinic Antagonist (LAMA)—TD-4208

        In November 2011, we announced positive topline results from a Phase 2a single-dose COPD study of TD-4208, an investigational inhaled LAMA, discovered by Theravance. In this study, TD-4208 met the primary endpoint by demonstrating a statistically significant mean change from baseline in peak forced expiratory volume in one second (FEV1) compared to placebo and was generally well tolerated.

Other Programs

        In addition to the programs listed above, we have other clinical-stage programs for bacterial infections, cognitive disorders and gastrointestinal motility.

41


Table of Contents

        TD-1792 is our investigational heterodimer antibiotic that combines the antibacterial activities of a glycopeptide and a beta-lactam in one molecule. The goal of our program with TD-1792 is to develop a next-generation antibiotic for the treatment of serious infections caused by Gram-positive bacteria.

        In cognitive disorders, we are evaluating compound TD-5108 as a potential treatment for Alzheimer's disease. TD-5108 has successfully completed a Phase 1 study assessing CNS penetration. Our Gastrointestinal (GI) Motility Dysfunction program is dedicated to finding new medicines for GI motility disorders such as chronic idiopathic constipation (CIC) and other disorders related to reduced gastrointestinal motility. Our lead compound in this area is TD-5108, a highly selective 5-HT4 receptor agonist that has successfully completed a 400 patient Phase 2 proof-of-concept study in CIC. The back-up compound in this program, TD-8954, has completed single-ascending and multiple-ascending dose Phase 1 studies.

Critical Accounting Policies

        This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported revenue and expenses during the reporting periods. We periodically evaluate our material estimates and judgments based on the terms of underlying agreements, the expected course of development, historical experience and other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

        While our significant accounting policies are more fully described in Note 1, "Description of Operations and Summary of Significant Accounting Policies," in the Notes to our consolidated financial statements contained in Part II, Item 8, "Financial Statements and Supplementary Data" in this Annual Report on Form 10-K, we believe that the following accounting policies relating to revenue recognition, preclinical study and clinical study expenses, stock-based compensation charges and inventory require us to make significant estimates, assumptions and judgments.

Revenue Recognition

        We recognize revenue in accordance with the Financial Accounting Standards Board (FASB) Subtopic ASC 605-25, "Revenue Recognition—Multiple-Element Arrangements." As of January 1, 2011, we adopted on a prospective basis the accounting updates to guidance ASC 605 "Revenue Recognition", subtopic ASC 605-25 "Revenue with Multiple Element Arrangements" and subtopic ASC 605-28 "Revenue Recognition-Milestone Method", which provides accounting guidance for revenue recognition for arrangements with multiple deliverables and guidance on defining the milestone and determining when the use of the milestone method of revenue recognition for research and development transactions is appropriate, respectively. The adoption of ASC 605-25 "Revenue with Multiple Element Arrangements" and the election of the milestone method under subtopic ASC 605-28 "Revenue Recognition-Milestone Method" did not have a material impact on our consolidated financial statements. However, these updates will result in different accounting treatment for future new collaboration arrangements and substantive milestones earned after the dates of adoption.

        Our revenues are related primarily to our collaboration arrangements with GSK and our collaboration agreement with Astellas, which was in effect through January 6, 2012 (see Collaboration Arrangements section below). Our arrangements provide for various types of payments to us, including non-refundable upfront license and other fees, milestone payments and royalty payments. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured.

42


Table of Contents

        For multiple-element arrangements entered into prior to January 1, 2011, we determined that the deliverables under our collaboration agreements with GSK and Astellas did not meet the criteria required for separate accounting units for the purposes of revenue recognition. As a result, we recognized revenue from non-refundable, upfront fees and development milestone payments ratably over the term of its performance under the agreements. These upfront or milestone payments received, pending recognition as revenue, are recorded as deferred revenue and are classified as a short-term or long-term liability on the balance sheet to be amortized over the period of deferral. We periodically review the estimated performance periods of our contracts based on the progress of its programs.

        In accordance with ASC Subtopic 808-10, "Collaborative Arrangement," and pursuant to our agreement with Astellas, we recognized as revenue the net impact of transactions with Astellas related to VIBATIV® inventory including revenue specifically attributable to any sales, and cost of inventory either transferred or expensed as unrealizable.

        We have recognized royalty revenue on net sales in the period in which the royalties are earned based on net sales reporting provided by Astellas, our former collaborative partner for VIBATIV®.

        We have been reimbursed by GSK and Astellas for certain external development costs under their respective collaboration agreements. Such reimbursements have been reflected as a reduction of research and development expense and not as revenue.

        For multiple-element arrangements entered into, or materially modified, subsequent to January 1, 2011, each deliverable within a multiple deliverable revenue arrangement is accounted for as a separate unit of accounting if both of the following criteria are met: (1) the delivered item or items have value to the customer on a standalone basis and (2) for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control.

        In addition, multiple deliverable revenue arrangement consideration is allocated at the inception of an arrangement to all deliverables using the relative selling price method. We also apply a selling price hierarchy for determining the selling price of a deliverable, which includes (1) vendor-specific objective evidence, if available, (2) third-party evidence, if vendor-specific objective evidence is not available, and (3) estimated selling price if neither vendor-specific nor third-party evidence is available.

        Where a portion of non-refundable upfront license or other payments, or milestone payments received are allocated to continuing performance obligations under the terms of a collaboration agreement, it will be recorded as deferred revenue and recognized as revenue ratably over the term of its estimated performance period under the agreement. We determine the estimated performance periods and they are periodically reviewed based on the progress of the related program. The effect of a change made to an estimated performance period and therefore revenue recognized ratably would occur on a prospective basis in the period that the change was made.

        Deferred revenue associated with a non-refundable payment received under a collaborative agreement that the performance obligations are terminated will result in an immediate recognition of any remaining deferred revenue in the period that termination occurred provided that all performance obligations have been satisfied.

        For milestones earned after January 1, 2011, we recognize revenue from milestone payments when: (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, and (ii) we do not have ongoing performance obligations related to the achievement of the milestone earned. Milestone payments are considered substantive if all of the following conditions are met: the milestone payment (a) is commensurate with either our performance to achieve the milestone or the enhancement of the value of the delivered item or items as a result of a specific outcome resulting from our performance to achieve the milestone, (b) relates solely to past performance, and (c) is reasonable relative to all of the deliverables and payment terms (including

other potential milestone consideration) within the arrangement. See Note 3, "Collaboration Arrangements," in the Notes to the Consolidated Financial Statements below in part II, Item 8, "Financial Statements and Supplementary Data" on this Annual Report on Form 10-K, for analysis of each milestone event deemed to be substantive or non-substantive.

Preclinical Study and Clinical Study Expenses

        A substantial portion of our preclinical studies and all of our clinical studies have been performed by third-party contract research organizations (CROs). Some CROs bill monthly for services performed, while others bill based upon milestones achieved. We review the activities performed under the significant contracts each quarter. For preclinical studies, the significant factors used in estimating accruals include the percentage of work completed to date and contract milestones achieved. For clinical study expenses, the significant factors used in estimating accruals include the number of patients enrolled and percentage of work completed to date. Vendor confirmations are obtained for contracts with longer duration when necessary to validate our estimate of expenses. Our estimates are highly dependent upon the timeliness and accuracy of the data provided by our CROs regarding the status of each program and total program spending and adjustments are made when deemed necessary. To date, we have not recorded any material adjustments as a result of changes to our estimates.

Stock-Based Compensation

        Stock-based compensation arrangements currently include stock options granted, restricted stock unit awards (RSUs) granted and restricted shares issued RSAs) under the 2004 Equity Incentive Plan (2004 Plan) and the 2008 New Employee Equity Incentive Plan (2008 Plan) and purchases of common stock by our employees at a discount to the market price during offering periods under our Employee Stock Purchase Plan (ESPP). Non-statutory options, RSUs, and RSAs were granted under the 2008 Plan to our newly hired employees until April 27, 2010, the date on which stockholders approved our amended and restated 2004 Plan. No further awards will be granted under the 2008 Plan.

        We use the Black-Scholes option pricing model to estimate the fair value of options granted under our equity incentive plans and rights to acquire stock granted under our employee stock purchase plan. The Black-Scholes option valuation model requires the use of assumptions, including the expected term of the award and the expected stock price volatility. We use the "simplified" method as described in Staff Accounting Bulletin No. 107 for the expected option term because the usage of our historical exercise data is limited due to post-IPO exercise restrictions. Since April 1, 2011, we have used our historical volatility to estimate expected stock price volatility. Prior to April 1, 2011, we used peer company price volatility to estimate expected stock price volatility due to our limited historical common stock price volatility since its initial public offering in 2004. Restricted stock units (RSUs) and stock awards are measured based on the fair market values of the underlying stock on the dates of grant.

        The estimated fair value of stock options, RSUs and RSAs are expensed on a straight-line basis over the expected term of the grant and the fair value of performance-contingent RSUs and performance-contingent RSAs are expensed during the term of the award when we determine that it is probable that certain performance milestones will be achieved. Compensation expense for purchases under the ESPP is recognized based on the estimated fair value of the common stock during each offering period and the percentage of the purchase discount.

        Stock-based compensation expense for stock options, RSUs and RSAs has been reduced for estimated forfeitures so that compensation expense is based on options, RSUs and RSAs ultimately expected to vest. We estimate annual forfeiture rates for stock options, RSUs and RSAs based on our historical forfeiture experience.

Inventory

        Inventory is stated at the lower of cost or market value and is included in prepaid and other current assets. Inventory was comprised of VIBATIV® active pharmaceutical ingredient. VIBATIV® has a limited shelf life. During the quarter ended December 31, 2011, we expensed all remaining inventory at an average cost basis of $0.5 million as it was no longer realizable.

Collaboration Arrangements

GSK

LABA collaboration with GSK

        In November 2002, we entered into our LABA collaboration with GSK to develop and commercialize once-daily LABA products for the treatment of COPD and asthma. For the treatment of COPD, the collaboration is developing combination products, RELOVAIR™ and the LAMA/LABA '719/VI. For the treatment of asthma, the collaboration is developing RELOVAIR™. RELOVAIR™ is an investigational once-daily combination medicine consisting of a LABA, VI, previously referred to as GW642444 or '444, and an ICS, fluticasone furoate (FF). The LAMA/LABA, '719/VI, is an investigational once-daily combination medicine consisting of the LAMA, '719, and the LABA, VI. The RELOVAIR™ program is aimed at developing a once-daily combination LABA/ICS to succeed GSK's Advair®/Seretide™ (salmeterol and fluticasone as a combination) franchise, which reported 2011 sales of approximately $8.1 billion, and to compete with Symbicort® (formoterol and budesonide as a combination), which reported 2011 sales of approximately $3.1 billion. '719/VI, which is also a combination product, is targeted as an alternative treatment option to Spiriva® (tiotropium), a once-daily, single-mechanism bronchodilator, which reported 2010 sales of approximately $3.8 billion.

        The current lead product candidates in the LABA collaboration, VI and FF, were discovered by GSK. In the event that VI is successfully developed and commercialized, we will be obligated to make milestone payments to GSK which could total as much as $220.0 million if both a single-agent and a combination product or two different combination products are launched in multiple regions of the world. If global regulatory authorities accept the applications for RELOVAIR™, which we anticipate will be filed by GSK beginning in mid-2012, a portion of these potential milestone payments could be payable to GSK within the next two years. We are entitled to annual royalties from GSK of 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. Sales of single-agent LABA medicines and combination medicines would be combined for the purposes of this royalty calculation. For other products combined with a LABA from the LABA collaboration, such as '719/VI, royalties are upward tiering and range from the mid-single digits to 10%. However, if GSK is not selling a LABA/ICS combination product at the time that the first other LABA combination is launched, then the royalties described above for the LABA/ICS combination medicine would be applicable.

        In connection with the LABA collaboration, in 2002, Glaxo Group Limited, an affiliate of GSK, purchased shares of our Series E preferred stock for an aggregate purchase price of $40.0 million.

2004 Strategic Alliance with GSK

        In March 2004, we entered into our strategic alliance with GSK. Under this alliance, GSK received an option to license exclusive development and commercialization rights to product candidates from certain of our discovery programs on pre-determined terms and on an exclusive, worldwide basis. Upon GSK's decision to license a program, GSK is responsible for funding all future development, manufacturing and commercialization activities for product candidates in that program. In addition, GSK is obligated to use diligent efforts to develop and commercialize product candidates from any program that it licenses. If the program is successfully advanced through development by GSK, we are entitled to receive clinical, regulatory and commercial milestone payments and royalties on any sales of medicines developed from the program. If GSK chooses not to license a program, we retain all rights to the program and may continue the program alone or with a third party.

        In 2005, GSK licensed our MABA program for the treatment of COPD, and in October 2011, we and GSK expanded the MABA program by adding six additional Theravance-discovered preclinical MABA compounds (the "Additional MABAs"). GSK's development, commercialization, milestone and royalty obligations under the strategic alliance remain the same with respect to '081, the lead compound in the MABA program. GSK is obligated to use diligent efforts to develop and commercialize at least one MABA within the MABA program, but may terminate progression of any or all Additional MABAs at any time and return them to us, at which point we may develop and commercialize such Additional MABAs alone or with a third party. Both GSK and we have agreed not to conduct any MABA clinical studies outside of the strategic alliance so long as GSK is in possession of the Additional MABAs. If a single-agent MABA medicine containing '081 is successfully developed and commercialized, we are entitled to receive royalties from GSK of between 10% and 20% of annual global net sales up to $3.5 billion, and 7.5% for all annual global net sales above $3.5 billion. If a MABA medicine containing '081 is commercialized only as a combination product, such as a MABA/ICS, the royalty rate is 70% of the rate applicable to sales of the single-agent MABA medicine. For single-agent MABA medicines containing an Additional MABA, we are entitled to receive royalties from GSK of between 10% and 15% of annual global net sales up to $3.5 billion, and 10% for all annual global net sales above $3.5 billion. For combination products containing an Additional MABA, such as a MABA/ICS, the royalty rate is 50% of the rate applicable to sales of the single-agent MABA medicine. If a MABA medicine containing '081 is successfully developed and commercialized in multiple regions of the world, we could earn total milestone payments up to $125.0 million for a single-agent medicine and up to $250.0 million for both a single-agent and a combination medicine. If a MABA medicine containing an Additional MABA is successfully developed and commercialized in multiple regions of the world, we could earn total milestone payments up to $129.0 million.

        In connection with the expansion of the MABA program, GSK relinquished its option right on our MonoAmine Reuptake Inhibitor (MARIN) program and Angiotensin Receptor-NEP Inhibitor (ARNI) program. GSK has no further option rights on any of our research or development programs under the strategic alliance.

        In May 2004, GlaxoSmithKline LLC, an affiliate of GSK, purchased 6,387,096 shares of our Class A common stock for an aggregate purchase price of $108.9 million and, upon the closing of our initial public offering on October 8, 2004, GlaxoSmithKline LLC purchased an additional 433,757 shares of Class A common stock for an aggregate purchase price of $6.9 million. In November 2010 Glaxo Group Limited, an affiliate of GSK, purchased 5,750,000 shares of our Common Stock for an aggregate purchase price of $129.4 million.

GSK Conversion of our Class A Common Stock and Purchases of Common Stock under our Governance Agreement with GSK

        In July 2011, GSK converted all of the shares of our Class A common stock held by its affiliates into 9,401,499 shares of our common stock on a one share-for-one share basis in accordance with the terms of our restated certificate of incorporation. In addition, Glaxo Group Limited purchased shares of our common stock pursuant to its periodic "top-up" rights under our governance agreement with GSK dated June 4, 2004, as amended, as follows:

GSK Upfront License Fees, Milestone Payments and Revenue

        In August 2011, we received a $3.0 million milestone payment from GSK for the initiation of the Phase 1 combination study in our MABA program.

        In October 2011, we received an upfront license payment of $1.0 million from GSK related to the Additional MABAs, which is being accounted for as a new arrangement under the updated multiple element arrangement accounting guidance. We allocated revenue from this upfront license payment and will allocate any potential contingent payments related to the Additional MABAs under the MABA program, as discussed above in the section entitled Critical Accounting Policies—Revenue Recognition, to each non-contingent element based upon the relative selling price of each element. We determined the license has standalone value because the license can be used for its intended purpose and may be developed, commercialized and manufactured for its intended purpose without any remaining participation from us. As a result, we recognized $936,000 of the upfront license payment and the remaining amount was deferred and will be amortized over the estimated development period over which we will be performing services.

        Any eligible potential contingent payments related to the MABA program are not deemed substantive due to the fact that the achievement of the event underlying the payment predominantly relates to GSK's performance of future development, manufacturing and commercialization activities for product candidates after licensing the program.

Astellas

        In November 2005, we entered into a global collaboration arrangement with Astellas for the development and commercialization of VIBATIV®. On January 6, 2012, Astellas exercised its right to terminate this agreement. The rights granted to Astellas ceased upon termination of the agreement and Astellas has stopped promotional sales efforts. Pursuant to the terms of the agreement, there are no termination payments required by either party and Astellas is entitled to a ten-year, 2% royalty on future net sales of VIBATIV®. To support the transition, Astellas will sell inventory to us, manage certain clinical and regulatory activities and respond to medical inquiries with respect to VIBATIV® until no later than March 31, 2012. We are evaluating global commercialization alternatives for VIBATIV® either alone or with partners.

        VIBATIV® (telavancin), a bactericidal, once-daily injectable antibiotic developed by us for the treatment of Gram-positive infections. The FDA has approved VIBATIV® for the treatment of complicated skin and skin structure infections (cSSSI) caused by susceptible Gram-positive bacteria including both methicillin-resistant (MRSA) and methicillin-susceptible strains of Staphylococcus aureus in adult patients. VIBATIV® is also approved in Canada for the treatment of cSSSI in adult patients. In September 2011, the European Commission granted marketing authorization for VIBATIV® for the treatment of adults with nosocomial pneumonia, including ventilator-associated pneumonia, known or suspected to be caused by MRSA when other alternatives are not suitable. However, in February 2012 the Committee for Medicinal Products for Human Use (CHMP) recommended to the European Commission that it suspend this marketing authorization because the single-source drug product supplier does not meet the Good Manufacturing Practice (GMP) requirements to allow the manufacture of VIBATIV®.

        Due to manufacturing issues at the single-source supplier of VIBATIV® drug product, VIBATIV® is currently subject to critical product shortages and regional supply outages in the U.S. If the issues at the manufacturer are not promptly resolved, obtaining supply would require identifying and qualifying an alternative manufacturer, which could take 12 to 24 months.

        Through December 31, 2011, we have received $191.0 million in upfront license, milestone and other fees from Astellas. We recorded these payments as deferred revenue and are amortizing them ratably over our estimated performance period (development and commercialization period). As a

        We recognize revenue from the amortization of upfront license fees and milestone payments related to our GSK LABA collaboration and strategic alliance agreements and our Astellas telavancin collaboration, which was terminated on January 6, 2012. In addition, we recognized revenue related to our Astellas telavancin collaboration from royalties from net sales of VIBATIV® and from the impact of VIBATIV® inventory transfers or dispositions.

        Revenue increased to $24.5 million in 2011 compared to 2010. This increase was due primarily to an (i) increase in royalty revenue of $1.3 million from higher net sales of VIBATIV®, (ii) an increase in revenue related to our GSK MABA program of $1.1 million reflecting primarily the Additional MABA upfront license fee, and (iii) a decrease in expense of $0.3 million related to VIBATIV® inventory that was no longer realizable. These increases in 2011 were partially offset by (i) a decrease in revenue related to our GSK strategic alliance agreement of $0.8 million resulting from the deferred revenue being fully amortized in the third quarter of 2011, (ii) a decrease in net proceeds of $1.1 million in 2011, compared to 2010, related to the delivery of VIBATIV® to Astellas, and (iii) a decrease in revenue of $0.4 million in 2011, compared to 2010, resulting from a change in the estimated performance period related to our GSK LABA collaboration.

        As a result of the termination of the VIBATIV® collaboration agreement with Astellas, future revenue from Astellas will be comprised of recognition in the first quarter of 2012 of the remaining non-cash, deferred upfront license fees and milestone payments, net of any estimated termination obligations, of approximately $125.0 million. Future revenue from GSK will include ongoing amortization of upfront license fees and milestone payments over their estimated performance periods. We periodically review and, if necessary, revise the estimated performance periods pursuant to these contracts.

        R&D expenses increased in 2011 compared to 2010, due primarily to clinical costs related to our PµMA and MARIN programs, laboratory supplies, and higher employee related expenses in 2011.

        R&D expenses decreased in 2010 compared to 2009, due primarily to lower external costs in 2010, partially offset by lower reimbursements received from third parties in 2010. Employee-related expenses increased in 2010 compared to 2009 due primarily to higher salary and benefits costs. Stock-based compensation decreased in 2010 compared to 2009, due primarily to a larger number of options that completed vesting in 2009.

Table of Contents

        During the first quarter of 2011, we granted special long-term retention and incentive equity awards to executive officers and certain employees and special long-term retention and incentive cash bonus awards to certain employees. The vesting of these awards is tied to the achievement of certain performance conditions over a six-year timeframe from 2011 through December 31, 2016 and continued employment, both of which must be satisfied in order for vesting to occur. The maximum potential expense for R&D associated with this program is $6.3 million related to stock-based compensation expense and $35.4 million related to cash bonus expense, which would be recognized in increments based on achievement of the performance conditions. During the third quarter of 2011, we granted an incentive equity award to a non-executive officer that has dual triggers of vesting based upon the achievement of a performance condition over a timeframe from 2011-2013 and continued employment through 2014, both of which must be satisfied in order for the award to vest in full. The maximum potential expense for R&D associated with this award is approximately $475,000, which would be recognized in increments based on achievement of the performance conditions. As of December 31, 2011, we determined that the achievement of the performance conditions under these awards was not probable and, as a result, no compensation expense has been recognized. Management believes that the likelihood of achieving all of the performance conditions under these awards is remote.

        We anticipate R&D expenses for 2012 to increase relative to 2011. R&D expenses in 2012 will be driven largely by employee related expenses, costs associated with our continued development efforts in our PµMA program for opioid-induced constipation with TD-1211, our MARIN program with TD-9855, and costs associated with our earlier stage clinical programs and our Hepatitis C virus (HCV) and cardiovascular programs in late-stage discovery, as well as new drug discovery programs. We have not provided program costs in detail because we do not track, and have not tracked, all of the individual components (specifically the internal cost components) of our research and development expenses on a program basis. We do not have the systems and processes in place to accurately capture these costs on a program basis.

        G&A expenses increased in 2011 compared to 2010, due primarily to higher employee related and external expenses offset by lower facilities related costs.

        G&A expenses increased in 2010 compared to 2009, due primarily to higher salary and benefits costs partially offset by lower external costs.

        During the first quarter of 2011, we granted special long-term retention and incentive equity awards to executive officers and certain employees and special long-term retention and incentive cash bonus awards to certain employees. The vesting of these awards is tied to the achievement of certain performance conditions over a six-year timeframe from 2011 through December 31, 2016 and continued employment, both of which must be satisfied in order for the vesting to occur. The maximum potential expense for G&A associated with this program is $25.6 million related to stock-based compensation expense and $4.4 million related to cash bonus expense, which would be recognized in increments based on achievement of the performance conditions. As of December 31, 2011, we determined that the achievement of the requisite performance conditions was not probable and, as a result, no compensation expense has been recognized. Management believes that the likelihood of achieving all of the performance conditions is remote.

        Interest expense is comprised primarily of interest expense and amortization of debt issuance costs on our convertible subordinated notes issued in January 2008.

Income Taxes

        At December 31, 2011, we had net operating loss carryforwards for federal income taxes of $1,068.2 million and federal research and development tax credit carryforwards of $43.2 million. We recorded a valuation allowance to offset in full the benefit related to our deferred tax assets because realization of these benefits is uncertain.

        We had unrecognized tax benefits of $42.6 million as of December 31, 2010 and $46.9 million as of December 31, 2011. If we eventually are able to recognize these uncertain positions, most of the $46.9 million of the unrecognized benefit would reduce the effective tax rate, except for excess tax benefits related to stock-based payments.

        Utilization of net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. We conducted an analysis through 2011 to determine whether an ownership change had occurred since inception. The analysis indicated that two ownership changes occurred in prior years. However, notwithstanding the applicable annual limitations, we estimate that no portion of the net operating loss or credit carryforwards will expire before becoming available to reduce federal and

state income tax liabilities. Annual limitations may result in expiration of net operating loss and tax credit carryforwards before some or all of such amounts have been utilized.

Liquidity and Capital Resources

Liquidity

        Since our inception, we have financed our operations primarily through private placements and public offerings of equity and debt securities and payments received under corporate collaboration arrangements. As of December 31, 2011, we had $240.9 million in cash, cash equivalents and marketable securities, excluding $0.9 million in restricted cash that was pledged as collateral for certain of our leases.

        We expect to incur substantial expenses as we continue our discovery and development efforts; particularly to the extent we advance our product candidates into clinical studies, which are very expensive. A Phase 2b program is underway in our PµMA program and we initiated a Phase 2 study for MARIN in late 2011. We also intend to invest in other assets in our pipeline, including our Hepatitis C virus (HCV) and cardiovascular programs in late-stage discovery, and to conduct a number of other non-clinical and clinical studies in 2012. On January 6, 2012, Astellas exercised its right to terminate our collaboration agreement for VIBATIV®. Pursuant to the terms of the termination agreement, we may purchase certain VIBATIV® inventory from Astellas in 2012. The purchase is subject to release of the inventory by a third-party manufacturer and may cost up to $11.0 million. We believe that our cash, cash equivalents and marketable securities will be sufficient to meet our anticipated operating needs for at least the next twelve months based upon current operating plans, milestone and royalty forecasts and spending assumptions. If our current operating plans, milestone and royalty forecasts or spending assumptions change, we may require additional funding sooner in the form of public or private equity offerings or debt financings. Furthermore, if in our view favorable financing opportunities arise, we may seek additional funding at any time. However, future financing may not be available in amounts or on terms acceptable to us, if at all. This could leave us without adequate financial resources to fund our operations as presently conducted. In addition, we regularly explore debt restructuring and/or reduction alternatives, including through tender offers, redemptions, repurchases or otherwise, all consistent with the terms of our debt agreements.

        Cash used in operations increased in 2011, compared to 2010, due primarily to higher uses of cash for operating liabilities.

        Cash used in investing activities increased in 2011, compared to 2010, resulting primarily from higher cash balances being invested in short-term investments during 2011, compared to 2010.

        Cash provided by financing activities decreased in 2011, compared to 2010, due primarily to net proceeds of $129.2 million received from our private equity placement with GSK in November 2010, net proceeds of $93.5 million received from our public offering of common stock that closed in March 2010 and $2.7 million in Qualifying Therapeutic Discovery Project Grants received from the National Institute of Health in December 2010. This decrease was partially offset by proceeds of $13.6 million received from sales of our common stock to an affiliate of GSK throughout 2011, an increase in

proceeds of $3.7 million resulting from the exercises of employee stock options in 2011, a $3.0 million milestone payment received from GSK for the initiation of a Phase 1 combination study in the MABA program in August 2011 and $1.0 million upfront license fee received from GSK for the Additional MABAs in October 2011.

Off-Balance Sheet Arrangements

        We lease various real properties under an operating lease that generally requires us to pay taxes, insurance, maintenance, and minimum lease payments. This lease has options to renew.

        We have not entered into any off-balance sheet financial arrangements and have not established any structured finance or special purpose entities. We have not guaranteed any debts or commitments of other entities or entered into any options on non-financial assets.

Contractual Obligations and Commercial Commitments

        In the table below, we set forth our enforceable and legally binding obligations and future commitments, as well as obligations related to all contracts that we are likely to continue, regardless of the fact that they were cancelable as of December 31, 2011. Some of the figures that we include in this table are based on management's estimate and assumptions about these obligations, including their duration, the possibility of renewal, anticipated actions by third parties, and other factors. Because these estimates and assumptions are necessarily subjective, the obligations we will actually pay in future periods may vary from those reflected in the table.

In January 2008, we closed an underwritten public offering of $172.5 million aggregate principal amount of unsecured convertible subordinated notes that will mature on January 15, 2015. The financing raised proceeds, net of issuance costs, of $166.7 million which is being used for general corporate purposes. The notes bear interest at the rate of 3.0% per year, that is payable semi-annually in arrears in cash on January 15 and July 15 of each year, beginning on July 15, 2008. The notes are convertible, at the option of the holder, into shares of our common stock at an initial conversion rate of 38.6548 shares per $1,000 principal amount of the notes, subject to adjustment in certain circumstances, which represents an initial conversion price of approximately $25.87 per share.

Amount due is less than $50,000.

        We indemnify our officers and directors for certain events or occurrences, subject to certain limits. We may be subject to contingencies that may arise from matters such as product liability claims, legal proceedings, shareholder suits and tax matters, as such, we are unable to estimate the potential exposure related to these indemnification agreements. We have not recognized any liabilities relating to these agreements as of December 31, 2011.

        Pursuant to our LABA collaboration with GSK, we will be obligated to make milestone payments to GSK which could total as much as $220.0 million if both a single-agent and a combination product or two different combination products are launched in multiple regions of the world with the current lead LABA, VI. If global regulatory authorities accept the applications for RELOVAIR™, which we anticipate will be filed by GSK beginning in mid-2012, a portion of these potential milestone payments could be payable to GSK within the next two years. We have not recognized any liabilities relating to this agreement as of December 31, 2011.

Recent Accounting Update

        In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, "Presentation of Comprehensive Income" an update to Accounting Standards Codification (ASC) Topic 220, "Comprehensive Income". The amendments of this update require that all nonowner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This update is to be applied retrospectively and is effective for financial statements issued for fiscal years, and interim periods within those years, beginning after December 15, 2011, and interim and annual periods thereafter. This update will be effective for us January 1, 2012. We do not expect the adoption of this guidance to have a material impact on our condensed consolidated financial statements

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        We are exposed to market risk, including changes to interest rates which are confined to our cash, cash equivalents, restricted cash and marketable securities. We have invested primarily in money market funds, federal agency notes, corporate debt securities and U.S. treasury notes. To reduce the volatility relating to these exposures, we have put investment and risk management policies and procedures in place. The securities in our investment portfolio are not leveraged, are classified as available-for-sale and, due to their very short-term nature, are subject to minimal interest rate risk. We currently do not engage in hedging activities. Because of the short-term maturities of our investments, we do not believe that an increase in market rates would have any significant negative impact on the realized value of our investment portfolio. Our outstanding note payable has a fixed interest rate and therefore, we have no exposure to interest rate fluctuations.

        Most of our transactions are conducted in U.S. dollars, although we do conduct some preclinical activities and manufacture some active pharmaceutical ingredients with vendors located outside the United States. Some of these expenses are paid in U.S. dollars, and some are paid in the local foreign currency. If the exchange rate undergoes a change of 10%, we do not believe that it would have a material impact on our results of operations or cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Operations and Summary of Significant Accounting Policies

Description of Operations

        Theravance, Inc. (the Company or Theravance) is a biopharmaceutical company with a pipeline of internally discovered product candidates and strategic collaborations with pharmaceutical companies. Theravance is focused on the discovery, development and commercialization of small molecule medicines across a number of therapeutic areas including respiratory disease, bacterial infections, and central nervous system (CNS)/pain. By leveraging the Company's proprietary insight of multivalency to drug discovery, Theravance is pursuing a best-in-class strategy designed to discover superior medicines in areas of significant unmet medical need.

Principles of Consolidation

        The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Management's Estimates

        The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

Segment Reporting

        The Company has determined that it operates in a single segment which is the research and development of human therapeutics. Revenues are generated primarily from the Company's collaborations with GlaxoSmithKline plc (GSK), located in the United Kingdom and, through 2011, Astellas Pharma Inc. (Astellas), located in Japan. All long-lived assets are maintained in the United States.

Cash and Cash Equivalents

        The Company considers all highly liquid investments purchased with a maturity of three months or less on the date of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value.

        Under certain lease agreements and letters of credit, the Company has pledged cash and cash equivalents as collateral. Restricted cash related to such agreements was $0.9 million as of December 31, 2011 and December 31, 2010.

Marketable Securities

        The Company determines the appropriate classification of its marketable securities, which consist of debt securities, at the time of purchase and reevaluates such designation at each balance sheet date. All of the marketable securities are classified as available-for-sale and carried at estimated fair values and reported in either cash equivalents or marketable securities. Unrealized gains and losses on available-for-sale securities are reported in accumulated other comprehensive income as a separate component of stockholders' net capital deficiency. Interest, amortization of purchase premiums and

discounts, and realized gains and losses on sales of securities are included in interest and other income. The cost of securities sold is based on the specific identification method.

        The Company regularly reviews all of its investments for other-than-temporary declines in fair value. The Company's review includes the consideration of the cause of the impairment, including the creditworthiness of the security issuers, the number of securities in an unrealized loss position, the severity and duration of the unrealized losses, whether the Company has the intent to sell the securities and whether it is more likely than not that the Company will be required to sell the securities before the recovery of their amortized cost basis. When the Company determines that the decline in fair value of an investment is below the amortized cost basis and the decline is other-than-temporary, the Company reduces the carrying value of the security and records a loss for the amount of such decline.

Fair Value of Financial Instruments

        Financial instruments include cash equivalents, marketable securities, related party receivables, accounts payable, accrued liabilities and convertible subordinated notes. Marketable securities are carried at estimated fair value. The carrying value of cash equivalents, receivables from related party, accounts payable and accrued liabilities approximate their fair value due to the relatively short nature of these instruments. Convertible subordinated notes are described in Note 7.

Concentration of Credit Risks

        The Company invests in a variety of financial instruments and, by its policy, limits the amount of credit exposure with any one issuer, industry or geographic area for investments other than instruments backed by the U.S. federal government.

Notes Receivable

        The Company provided loans to certain employees to assist them primarily with the purchase of a primary residence, which collateralizes the resulting loans. There was no interest receivable related to the loans as of December 31, 2011 and December 31, 2010. The outstanding loans have maturity dates ranging from July 2012 through May 2014.

Inventory

        Inventory is stated at the lower of cost or market value and is included in prepaid and other current assets in the accompanying consolidated balance sheets. Inventory is comprised of VIBATIV® active pharmaceutical ingredient. VIBATIV® has a limited shelf life. Astellas purchased VIBATIV® inventory from the Company at a cost of $1.2 million in 2011 and $2.0 million in 2010. The Company expensed inventory, on an average cost basis, that was no longer realizable of $0.5 million in 2011, $0.8 million in 2010 and $1.2 million in 2009. Inventory was valued at zero at December 31, 2011 and $1.7 million at December 31, 2010.

Property and Equipment

        Property, equipment and leasehold improvements are stated at cost and depreciated using the straight-line method as follows:

Leasehold improvements

  Shorter of remaining lease terms or useful life

Equipment, furniture and fixtures

  5 - 7 years

Software and computer equipment

  3 years

Capitalized Software

        The Company capitalizes certain costs related to direct material and service costs for software obtained for internal use. Capitalized software costs are depreciated over 3 years.

Impairment of Long-Lived Assets

        Long-lived assets include property and equipment. The carrying value of long-lived assets is reviewed for impairment whenever events or changes in circumstances indicate that the asset may not be recoverable. An impairment loss is recognized when the total of estimated future cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount.

Bonus Accruals

        The Company has short-term bonus programs for eligible employees. Bonuses are determined based on various criteria, including the achievement of corporate, departmental and individual goals. Bonus accruals are estimated based on various factors, including target bonus percentages per level of employee and probability of achieving the goals upon which bonuses are based. The Company's management periodically reviews the progress made towards the goals under the bonus programs. As bonus accruals are dependent upon management's judgments of the likelihood of achieving the various goals, it is possible for bonus expense to vary significantly in future periods if changes occur in those management estimates.

Deferred Rent

        Deferred rent consists of the difference between cash payments and the recognition of rent expense on a straight-line basis for the buildings the Company occupies. Rent expense is being recognized ratably over the life of the leases. Because the Company's facility operating leases provide for rent increases over the terms of the leases, average annual rent expense during the first 1.5 years of the leases exceeded the Company's actual cash rent payments. Also included in deferred rent are lease incentives of $2.6 million as of December 31, 2011, which is being recognized ratably over the life of the leases.

Revenue Recognition

        The Company recognizes revenue in accordance with Financial Accounting Standards Board (FASB) Subtopic ASC 605-25, "Revenue Recognition—Multiple-Element Arrangements." As of January 1, 2011, the Company adopted on a prospective basis the accounting updates to guidance ASC 605 "Revenue Recognition", subtopic ASC 605-25 "Revenue with Multiple Element Arrangements"

and subtopic ASC 605-28 "Revenue Recognition-Milestone Method", which provides accounting guidance for revenue recognition for arrangements with multiple deliverables and guidance on defining the milestone and determining when the use of the milestone method of revenue recognition for research and development transactions is appropriate, respectively. The adoption of ASC 605-25 "Revenue with Multiple Element Arrangements" and the election of the milestone method under subtopic ASC 605-28 "Revenue Recognition-Milestone Method" did not have a material impact on the Company's consolidated financial statements. However, these updates will result in different accounting treatment for future new collaboration arrangements and substantive milestones earned after the dates of adoption.

        The Company's revenues are related primarily to its collaboration arrangements with GSK and, through 2011, with Astellas (see Note 3, "Collaboration Arrangements" for more information). The Company's arrangements provide for various types of payments to the Company, including non-refundable upfront fees and milestone payments and royalty payments. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured.

        For multiple-element arrangements entered into prior to January 1, 2011, the Company determined the deliverables under its collaboration agreements with GSK and Astellas did not meet the criteria required for separate accounting units for the purposes of revenue recognition. As a result, the Company recognized revenue from non-refundable, upfront fees and development milestone payments ratably over the term of its performance under the agreements. These upfront or milestone payments received, pending recognition as revenue, are recorded as deferred revenue and are classified as a short-term or long-term liability on the balance sheet to be amortized over the period of deferral. The Company periodically reviewed the estimated performance periods of its contracts based on the progress of its programs.

        In accordance with ASC Subtopic 808-10, "Collaborative Arrangement," and pursuant to the Company's agreement with Astellas, the Company recognized as revenue the net impact of transactions with Astellas related to VIBATIV® inventory including revenue specifically attributable to any sales, and cost of inventory either transferred or expensed as unrealizable.

        The Company recognizes royalty revenue on net sales in the period in which the royalties are earned based on net sales reporting provided by the Company's former collaboration partner, Astellas.

        The Company has been reimbursed by GSK and Astellas for certain external development costs under their respective collaboration agreements. Such reimbursements have been reflected as a reduction of research and development expense and not as revenue.

        For multiple-element arrangements entered into, or materially modified, subsequent to January 1, 2011, each deliverable within a multiple deliverable revenue arrangement is accounted for as a separate unit of accounting if both of the following criteria are met: (1) the delivered item or items have value to the customer on a standalone basis and (2) for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the Company's control.

        In addition, multiple deliverable revenue arrangement consideration is allocated at the inception of an arrangement to all deliverables using the relative selling price method. The Company also applies a selling price hierarchy for determining the selling price of a deliverable, which includes

(1) vendor-specific objective evidence, if available, (2) third-party evidence, if vendor-specific objective evidence is not available, and (3) estimated selling price if neither vendor-specific nor third-party evidence is available.

        Where a portion of non-refundable upfront license or other payments, or milestone payments received are allocated to continuing performance obligations under the terms of a collaborative agreement, it will be recorded as deferred revenue and recognized as revenue ratably over the term of its estimated performance period under the agreement. The Company determines the estimated performance periods and they are periodically reviewed based on the progress of the related program. The effect of a change made to an estimated performance period and therefore revenue recognized ratably would occur on a prospective basis in the period that the change was made.

        Deferred revenue associated with a non-refundable payment received under a collaborative agreement that the performance obligations are terminated will result in an immediate recognition of any remaining deferred revenue in the period that termination occurred provided that all performance obligations have been satisfied.

        For milestones earned after January 1, 2011, the Company recognizes revenue from milestone payments when (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement and (ii) the Company does not have ongoing performance obligations related to the achievement of the milestone earned. Milestone payments are considered substantive if all of the following conditions are met: the milestone payment (a) is commensurate with either the Company's performance to achieve the milestone or the enhancement of the value of the delivered item or items as a result of a specific outcome resulting from the Company's performance to achieve the milestone, (b) relates solely to past performance, and (c) is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. See Note 3, "Collaboration Arrangements," for analysis of each milestone event deemed to be substantive or non-substantive.

Research and Development Costs

        Research and development costs are expensed in the period that services are rendered or goods are received. Research and development costs consist of salaries and benefits, laboratory supplies and facility costs, as well as fees paid to third parties that conduct certain research and development activities on behalf of the Company, net of certain external research costs reimbursed by GSK and, through 2011, Astellas.

Preclinical Study and Clinical Study Expenses

        Most of the Company's preclinical studies and all of its clinical studies have been performed by third-party contract research organizations (CROs). Some CROs bill monthly for services performed, while others bill based upon milestones achieved. The Company reviews the activities performed under the significant contracts each quarter. For preclinical studies, the significant factors used in estimating accruals include the percentage of work completed to date and contract milestones achieved. For clinical study expenses, the significant factors used in estimating accruals include the number of patients enrolled and percentage of work completed to date. Vendor confirmations are obtained for contracts with longer duration when necessary to validate the Company's estimate of expenses. The Company's estimates are highly dependent upon the timeliness and accuracy of the data provided by its CROs

regarding the status of each program and total program spending and adjustments are made when deemed necessary.

Fair Value of Stock-Based Compensation Awards

        Stock-based compensation arrangements currently include the following awards granted under the 2004 Equity Incentive Plan (2004 Plan) and the 2008 New Employee Equity Incentive Plan (2008 Plan): stock options, restricted stock unit awards (RSUs), performance-contingent RSUs, restricted stock awards (RSAs), and performance-contingent RSAs. In addition, purchases of common stock by the Company's employees at a discount to the market price during offering periods under the Company's Employee Stock Purchase Plan (ESPP). Under the 2004 Plan and 2008 Plan, stock options may be granted with an exercise price not less than 100% of the fair market value of the common stock on the date of grant. Stock options are generally granted with terms of up to ten years and vest over a period of four years.

        The Company uses the Black-Scholes option pricing model to estimate the fair value of options granted under its equity incentive plans and rights to acquire stock granted under its employee stock purchase plan. The Black-Scholes option valuation model requires the use of assumptions, including the expected term of the award and the expected stock price volatility. The Company used the "simplified" method as described in Staff Accounting Bulletin No. 107 for the expected option term because the usage of its historical exercise data is limited due to post-IPO exercise restrictions. Beginning April 1, 2011, the Company used its historical volatility to estimate expected stock price volatility. Prior to April 1, 2011, the Company used peer company price volatility to estimate expected stock price volatility due to the Company's limited historical common stock price volatility since its initial public offering in 2004. RSUs and RSAs are measured based on the fair market values of the underlying stock on the dates of grant.

        Stock-based compensation expense was calculated based on awards ultimately expected to vest and has been reduced for estimated forfeitures at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company's estimated annual forfeiture rates for stock options, RSUs and RSAs are based on its historical forfeiture experience.

        The estimated fair value of stock options, RSUs and RSAs is expensed on a straight-line basis over the expected term of the grant and the fair value of performance-contingent RSUs and RSAs is expensed during the term of the award when the Company determines that it is probable that certain performance milestones will be achieved. Compensation expense for purchases under the ESPP is recognized based on the estimated fair value of the common stock during each offering period and purchase discount percentage.

        The Company has not recognized, and does not expect to recognize in the near future, any tax benefit related to employee stock-based compensation costs as a result of the full valuation allowance on the Company's net deferred tax assets including deferred tax assets related to its net operating loss carryforwards.

Income Taxes

        The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Comprehensive Loss

        Comprehensive loss is comprised of net loss and other comprehensive income (loss). Other comprehensive income (loss) consists of changes in unrealized gains and losses on the Company's available-for-sale securities. Comprehensive income or loss for the years ended December 31, 2011, 2010 and 2009 has been presented in the Company's Consolidated Statements of Stockholders' Net Capital Deficiency.

Related Parties

        Transactions with GSK are described in Note 3, "Collaboration Arrangements".

        Robert V. Gunderson, Jr. is a director of the Company. The Company has engaged Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, of which Mr. Gunderson is a partner, as its primary legal counsel. Fees are incurred in the ordinary course of business were $0.3 million in 2011, $0.7 million in 2010, and $0.4 million in 2009.

Recent Accounting Update

        In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, "Presentation of Comprehensive Income" an update to Accounting Standards Codification (ASC) Topic 220, "Comprehensive Income". This update requires that all nonowner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This update is to be applied retrospectively and is effective for financial statements issued for fiscal years, and interim periods within those years, beginning after December 15, 2011, and interim and annual periods thereafter. This update will be effective for the Company January 1, 2012. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

2. Net Loss per Share

        Basic net loss per share (basic EPS) is computed by dividing net loss by the weighted-average number of common shares outstanding during the period, less RSAs subject to forfeiture. Diluted net loss per share (diluted EPS) is computed by dividing net loss by the weighted-average number of common shares outstanding during the period, less RSAs subject to forfeiture, plus dilutive potential common shares. Diluted EPS is identical to basic EPS for all periods presented since potential common shares are excluded from the calculation, as their effect is anti-dilutive.

3. Collaboration Arrangements

GSK

LABA collaboration with GSK

        In November 2002, the Company entered into its long-acting beta2 agonist (LABA) collaboration with GSK to develop and commercialize once-daily LABA products for the treatment of chronic obstructive pulmonary disease (COPD) and asthma. For the treatment of COPD, the collaboration is developing combination products, RELOVAIR™ and the LAMA/LABA (GSK573719/vilanterol or '719/VI). For the treatment of asthma, the collaboration is developing RELOVAIR™. RELOVAIR™ is an investigational once-daily combination medicine consisting of a LABA, VI, previously referred to as GW642444 or '444, and an inhaled corticosteroid (ICS), fluticasone furoate (FF). The LAMA/LABA, '719/VI, is an investigational once-daily combination medicine consisting of the long-acting muscarinic antagonist (LAMA) '719, and the LABA, VI.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

3. Collaboration Arrangements (Continued)

        The current lead product candidates in the LABA collaboration, VI and FF, were discovered by GSK. In the event that VI is successfully developed and commercialized, the Company will be obligated to make milestone payments to GSK which could total as much as $220.0 million if both a single-agent and a combination product or two different combination products are launched in multiple regions of the world. If global regulatory authorities accept the applications for RELOVAIR™, which the Company anticipates will be filed by GSK beginning in mid-2012, a portion of these potential milestone payments could be payable to GSK within the next two years. The Company is entitled to annual royalties from GSK of 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. Sales of single-agent LABA medicines and combination medicines would be combined for the purposes of this royalty calculation. For other products combined with a LABA from the LABA collaboration, such as '719/VI, royalties are upward tiering and range from the mid-single digits to 10%. However, if GSK is not selling a LABA/ICS combination product at the time that the first other LABA combination is launched, then the royalties described above for the LABA/ICS combination medicine would be applicable.

        In connection with the LABA collaboration, in 2002, Glaxo Group Limited, an affiliate of GSK, purchased shares of the Company's Series E preferred stock for an aggregate purchase price of $40.0 million.

2004 Strategic Alliance with GSK

        In March 2004, the Company entered into its strategic alliance with GSK. Under this alliance, GSK received an option to license exclusive development and commercialization rights to product candidates from certain of the Company's discovery programs on pre-determined terms and on an exclusive, worldwide basis.

        Upon GSK's decision to license a program, GSK is responsible for funding all future development, manufacturing and commercialization activities for product candidates in that program. In addition, GSK is obligated to use diligent efforts to develop and commercialize product candidates from any program that it licenses. If the program is successfully advanced through development by GSK, the Company is entitled to receive clinical, regulatory and commercial milestone payments and royalties on any sales of medicines developed from the program. If GSK chooses not to license a program, the Company retains all rights to the program and may continue the program alone or with a third party.

        In 2005, GSK licensed the Company's bifunctional muscarinic antagonist-beta2 agonist (MABA) program for the treatment of COPD, and in October 2011, the Company and GSK expanded the MABA program by adding six additional Theravance-discovered preclinical MABA compounds (the "Additional MABAs"). GSK's development, commercialization, milestone and royalty obligations under the strategic alliance remain the same with respect to '081, the lead compound in the MABA program. GSK is obligated to use diligent efforts to develop and commercialize at least one MABA within the MABA program, but may terminate progression of any or all Additional MABAs at any time and return them to the Company, at which point the Company may develop and commercialize such Additional MABAs alone or with a third party. Both GSK and the Company have agreed not to conduct any MABA clinical studies outside of the strategic alliance so long as GSK is in possession of the Additional MABAs. If a single-agent MABA medicine containing '081 is successfully developed and commercialized, the Company is entitled to receive royalties from GSK of between 10% and 20% of annual global net sales up to $3.5 billion, and 7.5% for all annual global net sales above $3.5 billion. If

3. Collaboration Arrangements (Continued)

a MABA medicine containing '081 is commercialized only as a combination product, such as a MABA/ICS, the royalty rate is 70% of the rate applicable to sales of the single-agent MABA medicine. For single-agent MABA medicines containing an Additional MABA, the Company is entitled to receive royalties from GSK of between 10% and 15% of annual global net sales up to $3.5 billion, and 10% for all annual global net sales above $3.5 billion. For combination products containing an Additional MABA, such as a MABA/ICS, the royalty rate is 50% of the rate applicable to sales of the single-agent MABA medicine. If a MABA medicine containing '081 is successfully developed and commercialized in multiple regions of the world, the Company could earn total milestone payments up to $125.0 million for a single-agent medicine and up to $250.0 million for both a single-agent and a combination medicine. If a MABA medicine containing an Additional MABA is successfully developed and commercialized in multiple regions of the world, the Company could earn total milestone payments up to $129.0 million.

        In May 2004, GlaxoSmithKline LLC, an affiliate of GSK, purchased 6,387,096 shares of the Company's Class A common stock for an aggregate purchase price of $108.9 million and, upon the closing of the Company's initial public offering on October 8, 2004, GlaxoSmithKline LLC purchased an additional 433,757 shares of Class A common stock for an aggregate purchase price of $6.9 million. In November 2010 Glaxo Group Limited, an affiliate of GSK, purchased 5,750,000 shares of the Company's Common Stock for an aggregate purchase price of $129.4 million.

GSK Conversion of the Company's Class A Common Stock and Purchases of Common Stock under the Company's Governance Agreement with GSK

        In July 2011, GSK converted all of the shares of the Company's Class A common stock held by its affiliates into 9,401,499 shares of the Company's common stock on a one share-for-one share basis in accordance with the terms of the Company's restated certificate of incorporation. In addition, Glaxo Group Limited purchased shares of the Company's common stock pursuant to its periodic "top-up" rights under the Company's governance agreement with GSK dated June 4, 2004, as amended, as follows:

In August 2004, GSK exercised its right to license the Company's LAMA program pursuant to the terms of the strategic alliance. In 2009, GSK returned the program to the Company.

        In August 2011, the Company received a $3.0 million milestone payment from GSK for the initiation of the Phase 1 combination study in the Company's MABA program.

        In October 2011, the Company received an upfront license payment of $1.0 million from GSK related to the Additional MABAs, which is being accounted for as a new arrangement under the updated multiple element arrangement accounting guidance. The Company allocated revenue from this upfront license payment and will allocate any potential contingent payments related to the Additional MABAs under the MABA program, as discussed above in the section entitled Note 1, "Description of Operations and Summary of Significant Accounting Policies—Revenue Recognition," to each non-contingent element based upon the relative selling price of each element. The Company determined the license has standalone value because the license can be used for its intended purpose and may be developed, commercialized and manufactured for its intended purpose without any remaining participation from the Company's. As a result, the Company recognized $936,000 of the upfront license payment and the remaining amount was deferred and will be amortized over the estimated development period over which we will be performing services.

        The eligible potential contingent payments related to the MABA program, which includes the Additional MABAs, are not deemed substantive due to the fact that the achievement of the event underlying the payment predominantly relates to GSK's performance of future development, manufacturing and commercialization activities for product candidates after licensing the program.

The rights granted to Astellas ceased upon termination of the agreement and Astellas has stopped promotional sales efforts. Pursuant to the terms of the agreement, there are no termination payments required by either party and Astellas is entitled to a ten-year, 2% royalty on future net sales of VIBATIV®. To support the transition, Astellas will sell inventory to the Company, manage certain clinical and regulatory activities and respond to medical inquiries with respect to VIBATIV® until no later than March 31, 2012. The Company is evaluating global commercialization alternatives for VIBATIV® either alone or with partners.

        Through December 31, 2011, the Company received $191.0 million in upfront license, milestone and other fees from Astellas. The Company recorded these payments as deferred revenue and is amortizing them ratably over its estimated performance period (development and commercialization period). As a result of the termination of the VIBATIV® collaboration agreement, the Company is no longer eligible to receive any further milestone payments.

        At December 31, 2011, all of the available-for-sale debt securities had contractual maturities within twelve months and the average duration of marketable securities was approximately five months. The Company does not intend to sell the investments which are in an unrealized loss position and it is unlikely that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity. The Company has determined that the gross unrealized losses on its marketable securities at December 31, 2011 were temporary in nature.

5. Fair Value Measurements

        The Company defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

        The Company's valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect the Company's market assumptions. The Company classifies these inputs into the following hierarchy:

Convertible Subordinated Notes

        In January 2008, the Company closed an underwritten public offering of $172.5 million aggregate principal amount of unsecured convertible subordinated notes which will mature on January 15, 2015. The financing raised proceeds, net of issuance costs, of $166.7 million. The notes bear interest at the rate of 3.0% per year, that is payable semi-annually in arrears in cash on January 15 and July 15 of each year, beginning on July 15, 2008. The fair value of debt was estimated based on the quoted price of the instrument on December 30, 2011.

        The notes are convertible, at the option of the holder, into shares of the Company's common stock at an initial conversion rate of 38.6548 shares per $1,000 principal amount of the notes, subject to adjustment in certain circumstances, which represents an initial conversion price of approximately $25.87 per share. The debt issuance costs, which are included in other long-term assets, are being amortized on a straight-line basis over the life of the notes. Unamortized debt issuance costs totaled $2.5 million as of December 31, 2011. Amortization expense was $0.8 million in 2011, 2010 and 2009.

        Holders of the notes will be able to require the Company to repurchase some or all of their notes upon the occurrence of a fundamental change (as defined) at 100% of the principal amount of the notes being repurchased plus accrued and unpaid interest. The Company may not redeem the notes prior to January 15, 2012. On or after January 15, 2012 and prior to the maturity date, the Company,

76


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

7. Long-Term Obligations (Continued)

upon notice of redemption, may redeem for cash all or part of the notes if the last reported sale price of its common stock has been greater than or equal to 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period prior to the date on which it provides notice of redemption. The redemption price will equal 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest up to but excluding the redemption date.

Note Payable

        In connection with the Company's original lease agreement for its facility in South San Francisco, California (see Note 8, "Operating Leases and Subleases," for more information), the Company received approximately $0.9 million in July 2002 under a tenant improvement loan from the lessor, which is payable in monthly installments through 2012, bears interest at 14.5% per annum and is secured by the underlying leasehold improvements. The aggregate maturity of the note payable for the remaining year was $42,000 in 2012 and is included in note payable and capital lease, current in the accompanying consolidated balance sheets.

Capital Lease

        The Company's capital lease agreement for communications equipment entered into in June 2009 is accounted for as follows:

        The equipment under the capital lease arrangement is included in property and equipment and the related amortization is included in depreciation and amortization expense in the consolidated statements of cash flows. The cost of equipment financed under capital leases was $0.2 million and the related accumulated amortization was $72,000 as of December 31, 2011 and $41,000 as of December 31, 2010.

8. Operating Leases and Subleases

        The Company entered into amendments to its South San Francisco, CA facility leases in June 2010. These amendments extend the lease terms through May 2020 and the Company may extend the terms for two additional five-year periods. The leases are for two buildings of approximately 110,000 and 40,000 square feet.

9. Commitments and Contingencies

Guarantees and Indemnifications

        The Company indemnifies its officers and directors for certain events or occurrences, subject to certain limits. The Company believes the fair value of these indemnification agreements is minimal. Accordingly, the Company has not recognized any liabilities relating to these agreements as of December 31, 2011.

Purchase Obligations

        As of December 31, 2011, the Company had outstanding purchase obligations on commercially reasonable terms, primarily for services under contract research, development and clinical supply agreements totaling $1.0 million.

10. Stock-Based Compensation

Equity Incentive Plans

        The Company authorized 500,000 shares of common stock for issuance under the 2008 Plan upon its adoption in 2008 and authorized an additional 200,000 shares for issuance under the 2008 Plan in July 2009. The 2008 Plan provided for the granting of non-qualified stock options, restricted stock awards and RSUs to newly hired employees. Following the approval by stockholders of the amendment

78


Table of Contents


THERAVANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

10. Stock-Based Compensation (Continued)

and restatement of the 2004 Plan on April 27, 2010, no additional awards have been made or will be made in the future under the 2008 Plan.

        The 2004 Plan provides for the granting of stock options, restricted stock awards, stock appreciation rights and RSUs to employees, officers, directors and consultants of the Company. On April 27, 2010, an amendment and restatement of the 2004 Plan was approved by the Company's stockholders to, among other things, reserve additional shares of common stock for issuance thereunder. As of December 31, 2011, total shares remaining available for issuance under the 2004 Plan were 2,090,098.

Employee Stock Purchase Plan

        Under the 2004 Employee Stock Purchase Plan (ESPP), the Company's non-officer employees may purchase common stock through payroll deductions at a price equal to 85 percent of the lower of the fair market value of the stock at the beginning of the offering period or at the end of each applicable purchase period. The ESPP provides for consecutive and overlapping offering periods of 24 months in duration, with each offering period composed of four consecutive six-month purchase periods. The purchase periods end on either May 15th or November 15th. ESPP contributions are limited to a maximum of 15 percent of an employee's eligible compensation.

        The Company's ESPP plan also includes a feature that provides for a new offering period to begin when the fair market value of the Company's common stock on any purchase date during an offering period falls below the fair market value of the Company's common stock on the first day of such offering period. This feature is called a reset. The Company had resets for new twenty-four month offering periods starting on November 16, 2007, May 16, 2008, November 16, 2008, May 16, 2010, and November 16, 2011. The Company applied modification accounting to determine the incremental fair value associated with the ESPP resets and recognized the related incremental stock-based compensation expense.

        As of December 31, 2011, a total of 2,025,000 shares of common stock were approved and authorized for issuance under the ESPP. Through December 31, 2011, the Company issued 1,468,454 shares under the ESPP at an average price of $10.15 per share. As of December 31, 2011, total shares remaining available for issuance under the ESPP were 556,546.

Restricted Stock Awards

        The Compensation Committee of the Company's Board of Directors approved the grant of 1,168,000 in 2011 and 71,000 shares in 2007, of restricted stock to certain members of the Company's management. These restricted shares of common stock vest based on continued service, with pre-determined vesting percentages and anniversary dates. The Company valued the awards based on the closing market price of the Company's common stock on the date of the respective awards.

Performance-Contingent Restricted Stock Awards

        In 2011, the Compensation Committee of the Company's Board of Directors approved the grant of 1,290,000 performance-contingent RSAs to senior management. These grants have dual triggers of vesting based upon the achievement of certain performance conditions over a six-year timeframe from 2011-2016 and continued employment, both of which must be satisfied in order for the RSAs to vest.

79


Table of Contents


THERAVANCE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

10. Stock-Based Compensation (Continued)

Expense associated with these RSAs would be recognized, if at all, during these years depending on the probability of meeting the performance conditions. The maximum potential expense associated with the RSAs could be up to approximately $31.9 million (allocated as $6.3 million for research and development expense and $25.6 million for general and administrative expense) if all of the performance conditions are achieved on time. As of December 31, 2011, the Company had determined that the achievement of the requisite performance conditions was not probable and, as a result, no compensation expense has been recognized. As the RSAs are dependent upon the achievement of certain performance conditions, the expense associated with the RSAs may vary significantly from period to period.

        In 2011, the Compensation Committee of the Company's Board of Directors approved the grant of 25,000 performance-contingent RSAs to a non-executive officer that has dual triggers of vesting based upon the achievement of a performance condition over a timeframe from 2012-2013 and continued employment through 2014, both of which must be satisfied in order for the award to vest in full. The maximum potential expense associated with this award is approximately $475,000, which would be recognized in increments based on the achievement of the performance condition. As of December 31, 2011, the Company had determined that the achievement of the requisite performance condition was not probable and, as a result, no compensation expense has been recognized. As the vesting of the RSAs is contingent upon the achievement of the performance condition, the expense associated with the RSAs may vary significantly from period to period.

Performance-Contingent Restricted Stock Units

        In 2010, the Compensation Committee of the Company's Board of Directors approved the grant of 210,000 performance-contingent RSUs to senior management. These awards have dual triggers of vesting based upon the successful achievement of certain corporate operating milestones during 2010 and 2011, as well as a requirement for continued employment through early 2014. As of February 11, 2011, both performance milestones had been deemed achieved, and time-based vesting commenced with respect to all of the performance-contingent RSU shares.

Director Compensation Program

        Non-employee directors of the Company receive compensation for services provided as a director. Each member of the Company's Board who is not an employee receives an annual retainer as well as a fee for each board and committee meeting attended. Commencing on April 27, 2011, chairpersons of the various committees of the Board, the Audit Committee, the Compensation Committee, Nominating/Corporate Governance Committee and the Science and Technology Advisory Committee receives a fixed retainer. The lead independent director also receives a fixed retainer.

        Each of the Company's independent directors receives periodic automatic grants of equity awards under a program implemented under the 2004 Plan. These grants are non-discretionary. Only independent directors of the Company or affiliates of such directors are eligible to receive automatic grants under the 2004 Plan. Under the program, as amended in July 2010, each individual who first becomes an independent director will, on the date such individual joins the Board, automatically be granted (i) a one-time grant of RSUs covering 6,000 shares of the Company's common stock and (ii) a one-time nonstatutory stock option grant covering 6,000 shares of the Company's common stock.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

10. Stock-Based Compensation (Continued)

        These initial equity grants vest monthly over the director's first two years of service. In addition, on the date of joining the Board, the new director will also receive the standard annual equity awards (if joining on the date of the Company's Annual Meeting of Stockholders) or pro-rated annual equity awards (if joining on any other date). The pro-ration is based upon the number of months of service the new board member will provide during the 12-month period ending on the one-year anniversary of the most recent annual meeting of stockholders. Annually, upon his or her re-election to the Board at the Annual Meeting of Stockholders, each independent director is automatically granted both an RSU covering 6,000 shares of the Company's common stock and a nonstatutory stock option covering 6,000 shares of the Company's common stock. These standard annual equity awards vest monthly over the twelve month period of service following the date of grant. In addition, all automatic equity awards vest in full if the Company is subject to a change in control or the Board member dies while in service.

As a result of the stock option modification, the Company recorded an expense of $0.9 million in June 2010.

11. Income Taxes

        Due to ongoing operating losses and the inability to recognize any income tax benefit, there is no provision for income taxes for any periods presented.

        Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax assets are as follows:

 
  December 31,  
(in thousands)
  2011   2010  

Deferred tax assets:

             

Net operating loss carryforwards

  $ 359,000   $ 311,000  

Deferred revenues

    56,000     63,000  

Capitalized research and development expenditures

    35,000     34,000  

Research and development tax credit carryforwards

    37,000     34,000  

Other

    31,000     26,000  

Valuation allowance

    (518,000 )   (468,000 )
           

Net deferred tax assets

  $   $  
           

        Realization of deferred tax assets is dependent on future taxable income, if any, the timing and the amount of which are uncertain. Accordingly, the deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $50.0 million in 2011, $35.0 million in 2010, and $32.0 million in 2009.

        As of December 31, 2011, the Company had federal net operating loss carryforwards of approximately $1,068.2 million, which will expire from 2012 through 2030, and federal research and development tax credit carryforwards of approximately $43.2 million, which will expire from 2018 through 2030. The Company also had state net operating loss carryforwards of approximately $425.0 million expiring in the years 2012 through 2030 and state research tax credits of approximately $46.9 million, which do not expire.

        The net operating loss deferred tax asset balances as of December 31, 2011 and 2010 do not include excess tax benefits from stock option exercises. Stockholders' net capital deficiency will be credited if and when such excess tax benefits are ultimately realized.

        Utilization of net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. The Company conducted an analysis through 2011 to determine whether an ownership change had occurred since inception. The analysis indicated that two ownership changes occurred in prior years. However, notwithstanding the applicable annual limitations, no portion of the net operating loss or credit carryforwards are expected to expire before becoming available to reduce federal and state income tax liabilities. Annual limitations may result in expiration of net operating loss and tax credit carryforwards before some or all of such amounts have been utilized.
