PART I

ITEM 1.    BUSINESS

Overview

        Innoviva, Inc. ("Innoviva", the "Company", the "Registrant" or "we" and other similar pronouns) is focused on bringing compelling new medicines to patients in areas of unmet need by leveraging its significant expertise in the development, commercialization and financial management of bio-pharmaceuticals. Innoviva's portfolio is anchored by the respiratory assets partnered with Glaxo Group Limited ("GSK"), including RELVAR^®/BREO^® ELLIPTA^® (fluticasone furoate/ vilanterol, "FF/VI") and ANORO^® ELLIPTA^® (umeclidinium bromide/ vilanterol, "UMEC/VI"). Under the Long-Acting Beta2 Agonist ("LABA") Collaboration Agreement and the Strategic Alliance Agreement with GSK (referred to herein collectively as the "GSK Agreements"), we are entitled to receive royalties from GSK on sales of RELVAR^®/BREO^® ELLIPTA^® as follows: 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. For other products combined with a LABA from the LABA collaboration, such as ANORO™ ELLIPTA™, royalties are upward tiering and range from 6.5% to 10%. Innoviva is also entitled to 15% of any future payments made by GSK under its agreements originally entered into with us, and since assigned to Theravance Respiratory Company, LLC ("TRC"), relating to the combination FF/UMEC/VI and the Bifunctional Muscarinic Antagonist-Beta2 Agonist ("MABA") program, as monotherapy and in combination with other therapeutically active components under the LABA Collaboration Agreement, which has been assigned to TRC other than RELVAR^®/BREO^®ELLIPTA^® and ANORO^® ELLIPTA^®. We do not manufacture or sell any of the products commercialized under the GSK Agreements, as it is the exclusive responsibility of GSK.

        Our headquarters are located at 2000 Sierra Point Parkway, Suite 500, Brisbane, CA 94005. Innoviva 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. In June 2014, we spun-off our research and development activities by distributing the outstanding shares of Theravance Biopharma, Inc. ("Theravance Biopharma") on a pro-rata basis to our stockholders (the "Spin-Off"), which resulted in Theravance Biopharma becoming an independent, publicly traded company. Following a rebranding exercise, we changed our name to Innoviva, Inc. in January 2016.

Our Strategy

        Innoviva uniquely combines deep pharmaceutical industry expertise and strategic financial management with the goal of maximizing the commercial potential and royalties we receive from our partnered pharmaceutical products. By channeling our significant expertise in the key field of pharmaceutical medicines including product development, commercialization, and financial strategy, Innoviva seeks to become a partner in the delivery of compelling new medicines that impact public health. We plan to leverage our unique industry knowledge and capabilities to identify medicines that have the potential to improve the lives of patients. This patient-centric approach is central to how Innoviva operates and collaborates with a partner to advance the availability of crucial medicines and treatments. Our corporate strategy is focused on stockholder returns by:

1.

Maximizing the potential value of our respiratory assets partnered with GSK;



2.

Providing capital returns to our investors through repurchases of equity and/or repurchases, redemptions or prepayments of debt;



3.

Optimizing our overall corporate cost of capital; and



4.

Building a long-term recurring revenue business.

Our Relationship with GSK

LABA Collaboration

        In November 2002, we entered into our LABA Collaboration Agreement with GSK to develop and commercialize once-daily products for the treatment of chronic obstructive pulmonary disease ("COPD") and

4

Table of Contents

asthma. The collaboration has developed two combination products: (1) RELVAR^®/BREO^® ELLIPTA^® (FF/VI) (BREO^® ELLIPTA^® is the proprietary name in the U.S. and Canada and RELVAR^® ELLIPTA^® is the proprietary name outside the U.S. and Canada), a once-daily combination medicine consisting of a LABA, vilanterol (VI), and an inhaled corticosteroid (ICS), fluticasone furoate (FF) and (2) ANORO^® ELLIPTA^® (UMEC/VI), a once-daily medicine combining a long-acting muscarinic antagonist ("LAMA"), umeclidinium bromide (UMEC), with a LABA. Under the LABA Collaboration Agreement, GSK and Innoviva are exploring various paths to create triple therapy medications. GSK is now responsible for all direct research and development activities associated with the collaboration.

        As a result of the launch and approval of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® in the U.S., Japan and Europe, we paid milestone fees to GSK totaling $220.0 million during the year ended December 31, 2014. Although we have no further milestone payment obligations to GSK pursuant to the LABA Collaboration Agreement, we continue to have ongoing participation as part of the collaboration, including joint steering and joint project committees that are expected to continue over the life of the agreement. The milestone fees paid to GSK were recognized as capitalized fees paid to a related party, which are being amortized over their estimated useful lives commencing upon the commercial launch of the products.

        We are entitled to receive royalties from GSK on sales of RELVAR^®/BREO^® ELLIPTA^® as follows: 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. For other products combined with a LABA from the LABA collaboration, such as ANORO™ ELLIPTA™, royalties are upward tiering and range from 6.5% to 10%.

2004 Strategic Alliance

        In March 2004, we entered into the Strategic Alliance Agreement with GSK where 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. 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 Innoviva-discovered preclinical MABA compounds (the "Additional MABAs"). The development program is funded in full by GSK and is currently in Phase II clinical studies. As a result of the transactions effected by the Spin-Off, we are only entitled to receive 15% of any contingent payments and royalties payable by GSK from sales of FF/UMEC/VI (and MABA, and MABA/FF) while Theravance Biopharma receives 85% of those same payments.

Agreements Entered into with GSK in Connection with the Spin-Off

        On March 3, 2014, in contemplation of the Spin-Off, we, Theravance Biopharma and GSK entered into a series of agreements clarifying how the companies would implement the Spin-Off and operate following the Spin-Off. We, Theravance Biopharma and GSK entered into a three-way master agreement providing for GSK's consent to the Spin-Off provided certain conditions were met.

        The amendments to the GSK Agreements do not change the economics or royalty rates under the GSK Agreements, though the assignment of the Strategic Alliance Agreement and portions of the LABA Collaboration Agreement to TRC do change how the economics are allocated between Theravance Biopharma and us. The amendments to the GSK Agreements do provide that GSK's diligent efforts obligations regarding commercialization matters under both agreements will change upon regulatory approval in either the United States or the European Union (the "EU") of FF/UMEC/VI or a MABA in combination with FF. Upon such regulatory approval, GSK's diligent efforts obligations as to commercialization matters under the GSK Agreements will have the objective of focusing on the best interests of patients and maximizing the net value of the overall portfolio of products under the GSK Agreements. Since GSK's commercialization efforts following such regulatory approval will be guided by a portfolio approach across products in which we will retain our full interests upon the Spin-Off and also products in which we have retained only a portion of our interests following the Spin-Off, GSK's commercialization efforts may have the effect of reducing the overall value of our remaining interests in the GSK Agreements following the Spin-Off.

Manufacturing

        Manufacturing of RELVAR^®/BREO^® ELLIPTA^® (FF/VI) and ANORO™ ELLIPTA™ (UMEC/VI) and for the MABA program is performed by GSK.

Government Regulation

        The development and commercialization of products and product candidates pursuant to the GSK Agreements are subject to extensive regulation by governmental authorities in the United States and other countries. Before marketing in the United States, any medicine must undergo rigorous preclinical studies and clinical studies and an extensive regulatory approval process implemented by the FDA. Outside the United States, the 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 reimbursement vary widely from country to country. In any country, the commercialization of medicines is permitted only if the appropriate regulatory authority is satisfied that our collaborative partner has presented adequate evidence of the safety, quality and efficacy of such medicines.

        Once a product is 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 regulatory approval for a medicine is obtained, the 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 cGMP regulations. The cGMP regulations for drugs contain minimum requirements for the methods, facilities, and controls used in manufacturing, processing, and packaging 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 and our collaborative partner 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 the development and commercialization of products and product candidates. 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 collaborative partner's ability to market partnered 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 and our collaborative partner will be able to protect our partnered technology from unauthorized use by third parties only to the extent that such 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 us and our collaborative partner obtaining patent protection for our partnered products and product candidates. Accordingly, patents and other proprietary rights are essential elements 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 business 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, 2016, we owned 33 issued United States patents and 97 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.

        United States issued patents and foreign patents generally expire 20 years after filing. 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 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.

Competition

        We anticipate that RELVAR^®/BREO^® ELLIPTA^® (FF/VI) and ANORO^® ELLIPTA^® (UMEC/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™ Diskus^®/HFA^® (salmeterol and fluticasone proprionate as a combination) marketed by GSK,



•

Symbicort^® (formoterol and budesonide as a combination) marketed by AstraZeneca,

        In addition, several firms are developing new formulations of Advair/Seretide (salmeterol /fluticasone proprionate) and Symbicort (formoterol fumerate/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 of our partnered products. Efforts have intensified following the publication of FDA draft guidance for the approval of fully substitutable versions of Advair and Symbicort in late 2013 and mid-2015 respectively. Current examples of these products include the marketed products Duoresp/Biresp from Teva (generic Symbicort), AirFluSal Forspiro by Sandoz, Rolenium by Elpen and Sirdupla by Mylan (all generic Advair) which are all available in a wide number of countries in the E.U. In the US, several competitors are attempting to gain market authorization for a generic version of Advair in the next one to two years. Chief among these are Mylan and Sandoz (Mylan reported filing of an ANDA with USFDA for their product in December 2015), Vectura and Roxane who own the U.S. rights to AirFluSal, and Teva who is developing both a fully substitutable and non-substitutable generic Advair that are expected to be filed in the next one to two years.

Employees

        As of December 31, 2016, we had 14 employees. None of our employees are represented by a labor union. We consider our employee relations to be good.

ITEM 1A.    RISK FACTORS

Risks Related to our Business

For the foreseeable future we will derive all of our royalty revenues from GSK and our future success depends on GSK's ability to successfully develop and commercialize the products in the respiratory programs partnered with GSK.

        Pursuant to the GSK Agreements, GSK is responsible for the development and commercialization of products in the partnered respiratory programs. Although we may receive milestone payments from GSK if certain development milestones are achieved in our MABA program, we believe that royalty revenues from RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® will represent the majority of our future revenues from GSK. The amount and timing of revenue from such royalties and milestones are unknown and highly uncertain. Our future success depends upon the performance by GSK of its commercial obligations under the GSK Agreements and the commercial success of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®. We have no control over GSK's marketing and sales efforts, and GSK might not be successful, which would harm our business and cause the price of our securities to fall.

        The amount of royalties and milestone payments, if any, we receive will depend on many factors, including the following:

•

the extent and effectiveness of the sales and marketing and distribution support GSK provides to our partnered products;

10

Table of Contents

•

market acceptance and demand for our partnered products;



•

changes in the treatment paradigm or standard of care for COPD or asthma, for instance through changes to the GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines;



•

the competitive landscape of generic and branded products and developing therapies that compete with our partnered products, including the closed triple combination for COPD or products owned by GSK (such as Advair^®) but which are not partnered with us and pricing pressure in the respiratory markets targeted by our partnered products;



•

the size of the market for our partnered products;



•

decisions as to the timing of product launches, pricing and discounts;



•

GSK reprioritizing its commercial efforts on other products, including the closed triple combination for COPD or products owned by GSK (such as Advair^®) but which are not partnered with us;



•

GSK's ability to expand the indications for which our partnered products can be marketed;



•

a satisfactory efficacy and safety profile as demonstrated in a broad patient population;



•

acceptance of, and ongoing satisfaction with, our partnered products by the medical community, patients receiving therapy and third party payors;



•

the ability of patients to be able to afford our partnered products or obtain health care coverage that covers our partnered products;



•

safety concerns in the marketplace for respiratory therapies in general and with our partnered products in particular;



•

regulatory developments relating to the manufacture or continued use of our partnered products;



•

the requirement to conduct additional post-approval studies or trials for our partnered products;



•

GSK's ability to successfully achieve development milestones with respect to our partnered MABA program;



•

GSK's ability to obtain regulatory approval of our partnered products in additional countries;



•

the unfavorable outcome of any potential litigation relating to our partnered products; or



•

general economic conditions in the jurisdictions where our partnered products are sold, including microeconomic disruptions or slowdowns.

If the FDA or other applicable regulatory authorities approve generic products, including but not limited to generic forms of Advair^®, that compete with RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®, or generic form of RELVAR^®/BREO^® ELLIPTA^®, the royalties payable to us pursuant to the LABA Collaboration Agreement will be less than anticipated, which in turn would harm our business and the price of our securities could fall.

        Once an NDA or marketing authorization application outside the United States is approved, the product covered thereby becomes a "listed drug" that can, in turn, be cited by potential competitors in support of approval of an Abbreviated New Drug Application ("ANDA") in the United States. Agency regulations and other applicable regulations and policies provide incentives to manufacturers to create modified, non-infringing versions of a drug to facilitate the approval of an ANDA or other application for generic substitutes in the United States and in nearly every pharmaceutical market around the world. Numerous companies like Mylan N.V., Novartis' Sandoz division and Teva Pharmaceuticals Industries Ltd. have publicly stated their intentions to bring generic forms of the ICS/LABA drug Advair^®, when certain patents covering the Advair^® delivery device expired in 2016. Mylan N.V. has recently announced that its ANDA for fluticasone propionate 100, 250, 500 mcg and salmeterol 50 mcg inhalation powder has been accepted for filing by the FDA with a GDUFA goal date of March 28, 2017. Hikma Pharmaceuticals PLC (Hikma) also recently announced that their ANDA for fluticasone propionate and salmeterol inhalation powder has been accepted for filing by the FDA with a GDUFA goal date of May 10, 2017. In addition, Teva Pharmaceutical Industries Ltd., (NYSE and TASE:

Table of Contents

TEVA) announced recently that the FDA approved two of their products for adolescent and adult patients with asthma, AirDuo™ RespiClick^® (fluticasone propionate and salmeterol inhalation powder) and ArmonAirTM RespiClick^® (fluticasone propionate inhalation powder), which are non-AB generic versions of Advair^®. In general, these manufactures are required to conduct a restricted number of clinical efficacy, pharmacokinetic and device studies to demonstrate equivalence to Advair, per FDA's September 2013 Draft Guidance document. These studies are designed to demonstrate that the generic product has the same active ingredient(s), dosage form, strength, exposure and clinical efficacy as the branded product. These generic equivalents, which must meet the same exacting quality standards as branded products, may be significantly less costly to bring to market, and companies that produce generic equivalents are generally able to offer their products at lower prices. Thus, after the introduction of a generic competitor, a significant percentage of the sales of any branded product and products that may compete with such branded product is typically lost to the generic product. In addition, on April 14, 2016, the FDA issued draft guidelines documents covering Fluticasone Furoate/Vilanterol Trifenatate (FF/VI), the active ingredients used in RELVAR^®/BREO^® ELLIPTA^®. Accordingly, introduction of generic products that compete against ICS/LABA products, like RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®, would materially adversely impact our future royalty revenue, profitability and cash flows. We cannot yet ascertain what impact these generic products and any future approved generic products will have on any sales of RELVAR^®/BREO^® ELLIPTA^® or ANORO^® ELLIPTA^®, if approved.

Reduced prices and reimbursement rates due to the actions of governments, payors, or competition or other healthcare cost containment initiatives such as restrictions on use, may negatively impact royalties generated under the GSK Agreements.

        The continuing efforts of governments, pharmaceutical benefit management organizations (PBMs), insurance companies, managed care organizations and other payors of health care costs to contain or reduce costs of health care has adversely affected the price, market access, and total revenues of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® and may continue to adversely affect them in the future. In addition, we have experienced and expect to continue to experience increased competitive activity which has resulted in lower overall prices for our products.

        The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (together, "PPACA") and other legislative or regulatory requirements or potential legislative or regulatory actions regarding healthcare and insurance matters, along with the trend toward managed healthcare in the U.S., could adversely influence the purchase of healthcare products and reduce demand and prices for our partnered products. This could harm GSK's ability to market our partnered products and significantly reduce future revenues. For example, when GSK launched BREO^® ELLIPTA^® for the treatment of COPD in the U.S. in October 2013, GSK experienced significant challenges gaining coverage at some of the largest PBMs, healthcare payors, and providers and lower overall prices than expected. Recent actions by U.S. PBMs in particular have increased discount levels for respiratory products resulting in lower net sales pricing realized for products in our collaboration. Further, if the ongoing Phase 3b studies with FF/VI do not show improved outcomes relative to the standard of care, obtaining payor coverage for RELVAR^®/BREO^® ELLIPTA^® could become more difficult 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 will continue and may increase. This may make it difficult for GSK to sell our partnered products at a price acceptable to us or GSK or to generate revenues in line with our analysts' or investors' expectations, which may cause the price of our securities to fall.

        More recently, the new presidential administration and the U.S. Congress have indicated that they may seek to replace PPACA and related legislation with new healthcare legislation. There is uncertainty with respect to the impact these potential changes may have, if any, and any changes will likely take time to unfold, and could have an impact on coverage and reimbursement for healthcare items and services covered by plans that were authorized by PPACA. However, we cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us.

        We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products once approved or additional pricing pressures, and may adversely affect our operating results.

All of our current revenues are from royalties derived from sales of our respiratory products partnered with GSK, RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®. If the treatment paradigm for the indications our partnered products are approved for change or if GSK is unable to, or does not devote sufficient resources to, maintain or continue increasing sales of these products, our results of operations will be adversely affected.

        We currently depend on royalties from sales of our products partnered with GSK to support our existing operations. Were the treatment paradigm for COPD or asthma to change, for instance through changes to the GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines, causing our partnered products to fall out of favor, or if GSK was unable, or did not devote sufficient resources, to maintain or continue increasing our partnered product sales, our results of operations would likely suffer and we may need to scale back our operations and capital return programs.

If the commercialization of RELVAR^®/BREO^® ELLIPTA^® or ANORO^® ELLIPTA^® in the countries in which they have received regulatory approval encounters any delays or adverse developments, or perceived delays or adverse developments, or if sales or payor coverage do not meet investors, analysts or our expectations, our business will be harmed, and the price of our securities could fall.

        Under our agreements with our collaborative partner GSK, GSK has full responsibility for commercialization of RELVAR^®/ BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®. GSK has launched RELVAR^®/ BREO^® ELLIPTA^® in a number of countries including the United States (U.S.), Canada, Japan, the United Kingdom, and Germany among others. The commercialization of both products in countries where they are already launched and the commercialization launch in new countries are still subject to fluctuating overall pricing levels and uncertain timeframes to obtain payor coverage. Any delays or adverse developments or perceived additional delays or adverse developments with respect to the commercialization of RELVAR^®/ BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® including if sales or payor coverage do not meet investors, analysts or our expectations, will significantly harm our business and the price of our securities could fall.

We are dependent on GSK for the successful commercialization and development of products under the GSK Agreements. If GSK does not devote sufficient resources to the commercialization or development of these products, is unsuccessful in its efforts, or chooses to reprioritize its commercial programs, including the closed triple product for COPD, our business will be materially harmed.

        GSK is responsible for all clinical and other product development, regulatory, manufacturing and commercialization activities for products developed under the GSK Agreements, including RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®. Our royalty revenues under the GSK Agreements may not meet our, analysts', or investors' expectations, due to a number of important factors. GSK has a substantial respiratory product portfolio in addition to the partnered products that are covered by the GSK Agreements. GSK may make respiratory product portfolio decisions or statements about its portfolio which may be, or may be perceived to be, harmful to the respiratory products partnered with us. For instance, GSK has wide discretion in determining the efforts and resources that it will apply to the commercialization of our partnered products. The timing and amount of royalties that we may receive will depend on, among other things, the efforts, allocation of resources and successful development and commercialization of these product candidates by GSK. In addition, GSK may determine to focus its commercialization efforts on its own products or the closed triple product for COPD following approval, if any. For example, in January 2015, GSK launched Incruse^® (Umec) in the U.S., which is a LAMA for the treatment of COPD. GSK may determine to focus its marketing efforts on Incruse, which could have the effect of decreasing the potential market share of ANORO^® ELLIPTA^® and lowering the royalties we may receive for such product. Alternatively, GSK may decide to market Incruse^® in combination with RELVAR^®/BREO^® ELLIPTA^® as an open triple therapy in anticipation of future commercialization of the closed triple therapy for which we only receive limited amount of royalty revenues, and eventually compete directly against sales of RELVAR^®/BREO^® ELLIPTA^®. For example, GSK filed for regulatory approval of the closed triple combination therapy for COPD in the U.S. in November 2016 and in the EU in December 2016. If the closed triple (or MABA /FF) receives regulatory approval in either the U.S. or the EU, GSK's diligent efforts obligations regarding commercialization matters will have the objective of focusing on the best interests of patients and maximizing the net value of the overall portfolio of products under the GSK Agreements. Since GSK's commercialization efforts following such regulatory approval will be guided by a portfolio approach

13

Table of Contents

across products in which we have retained our full interest and also products in which we now have only a small portion of our former interest, GSK's commercialization efforts may have the effect of reducing the overall value of our remaining interests in the GSK Agreements in the future. If GSK prioritizes the closed triple product for COPD following regulatory approval, if any, we will only be entitled to a 15% economic interest of the royalties paid pursuant to the GSK Agreements with respect to this product. In the event GSK does not devote sufficient resources to the commercialization of our partnered products or chooses to reprioritize its commercial programs, our business, operations and stock price would be negatively affected.

If the results of the Salford Lung Study in asthma are negative or do not meet market expectations, or if the data generated from the Salford study indicate safety concerns, sales of RELVAR^®/BREO^® ELLIPTA^® could be diminished and our ability to generate royalties from such sales could be negatively affected, and the price of our securities could fall.

        GSK is conducting the Salford Lung Study to explore the effectiveness of RELVAR^®/BREO^® ELLIPTA^® compared to other asthma treatments when used in a broad group of people living and managing their asthma on a day-to-day basis. The Salford Lung Study is a Phase 3 multicenter, randomized open-label study of approximately 2,800 people being treated in primary care who have been diagnosed and receive regular treatment for asthma in Salford and the surrounding area. The primary endpoint is the proportion of patients whose asthma is under control after 24 weeks receiving RELVAR^®/BREO^® ELLIPTA^® compared to usual maintenance therapy (where asthma control is defined by an ACT score of ³ 20). GSK expects to report results for the Salford Lung Study in asthma in 2017.

        If the data derived from the study are negative, do not meet market expectations, or identify other safety or efficacy concerns with RELVAR/BREO ELLIPTA, it could result in, among other things:

•

decreased market acceptance and demand for RELVAR^®/BREO^® ELLIPTA^®;



•

decrease in the size of the market for RELVAR^®/BREO^® ELLIPTA^®;



•

safety concerns in the marketplace for RELVAR^®/BREO^® ELLIPTA^®;



•

shifts in the medical community to new treatment paradigms or standards of care;



•

changes in the competitive landscape for approved and developing therapies that may compete with RELVAR^®/BREO^® ELLIPTA^®;



•

GSK's ability to obtain regulatory approval for RELVAR^®/BREO^® ELLIPTA^® in additional jurisdictions;



•

the unfavorable outcome or other negative effects of any potential litigation relating to RELVAR^®/BREO^® ELLIPTA^®;



•

additional restrictions on the commercialization of RELVAR^®/BREO^® ELLIPTA^® through changes to the approved RELVAR^®/BREO^® ELLIPTA^® labels;



•

the imposition of additional post-approval studies or trials; or



•

the withdrawal of the approvals of RELVAR^®/BREO^® ELLIPTA^®.

        Our business, operations and stock price would be negatively affected if any of these or similar events occur.

Any adverse change in FDA policy or guidance regarding the use of LABAs to treat asthma may significantly harm our business and the price of our securities could fall.

        On February 18, 2010, the FDA announced that LABAs should not be used alone in the treatment of asthma and it 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, in March 2010, the FDA held an Advisory

14

Table of Contents

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 prospects for FF/VI. 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 the FDA requiring additional asthma clinical trials in the U.S. for FF/VI and increase the overall risk of FF/VI for the treatment of asthma in the U.S. We cannot predict the extent to which new FDA policy or guidance might significantly impede the discovery, development, production and marketing of FF/VI. Any adverse change in FDA policy or guidance regarding the use of LABAs to treat asthma may significantly harm our business and the price of our securities could fall.

Any adverse developments to the regulatory status of either RELVAR^®/BREO^® ELLIPTA^® or ANORO^® ELLIPTA^® in the countries in which they have received regulatory approval including labeling restrictions, safety findings, or any other limitation to usage, will harm our business and may cause the price of our securities to fall.

        Although RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® are approved and marketed in a number of countries, it is possible that adverse changes to the regulatory status of these products could occur in the event new safety issues are identified, treatment guidelines are changed, or new studies fail to demonstrate product benefits. A number of notable pharmaceutical products have experienced adverse developments during commercialization that have resulted in the product being withdrawn, approved uses being limited, or new warnings being included. In the event that any adverse regulatory change was to occur to any of our products, our business will be harmed and the price of our securities could fall.

Any adverse developments or results or perceived adverse developments or results with respect to the ongoing studies for FF/VI in asthma or COPD, for UMEC/VI in COPD, or any future studies will significantly harm our business and the price of our securities could fall, and if regulatory authorities in those countries in which approval has not yet been granted determine that the ongoing studies for FF/VI in asthma or COPD or the ongoing studies for UMEC/VI for COPD do not demonstrate adequate safety and efficacy, the continued development of FF/VI or UMEC/VI or both may be significantly delayed, they may not be approved by these regulatory authorities, and even if approved it may be subject to restrictive labeling, any of which will harm our business, and the price of our securities could fall.

        Although we have announced the completion of, and reported certain top-line data from, the Phase 3 registrational program for FF/VI in COPD and asthma, additional studies of FF/VI are underway. Any adverse developments or perceived adverse developments with respect to any prior, current or future studies in these programs will significantly harm our business and the price of our securities could fall. For example, in September 2015, GSK and we announced that the Study to Understand Mortality and MorbidITy" (SUMMIT) did not meet its primary endpoints, which resulted in a significant decline in the price of our stock.

        Although the FDA, the European Medicines Agency, the Japanese Ministry of Health, Labour and Welfare and Health Canada and other jurisdictions have approved ANORO^® ELLIPTA^®, it has not yet been approved in all jurisdictions.

        Any adverse developments or results or perceived adverse developments or results with respect to other pending or future regulatory submissions for the FF/VI program or the UMEC/VI program will significantly harm our business and the price of our securities could fall. Examples of such adverse developments include, but are not limited to:

•

not every study, nor every dose in every study, in the Phase 3 programs for FF/VI achieved its primary endpoint and regulatory authorities may determine that additional clinical studies are required;



•

safety, efficacy or other concerns arising from clinical or non-clinical studies in these programs having to do with the LABA VI, which is a component of FF/VI and UMEC/VI;

Table of Contents

•

analysts adjusting their sales forecasts downward from previous projections based on results or interpretations of results of prior, current or future studies;



•

safety, efficacy or other concerns arising from clinical or non-clinical studies in these programs;



•

regulatory authorities determining that the Phase 3 programs in asthma or in COPD raise safety concerns or do not demonstrate adequate efficacy; or



•

any change in FDA (or comparable foreign regulatory agency) policy or guidance regarding the use of LABAs to treat asthma or the use of LABAs combined with a LAMA to treat COPD.

RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® face substantial competition for their intended uses in the targeted markets from products discovered, developed, launched and commercialized both by GSK and by other pharmaceutical companies, which could cause the royalties payable to us pursuant to the LABA Collaboration Agreement to be less than expected, which in turn would harm our business and the price of our securities could fall.

        GSK has responsibility for obtaining regulatory approval, launching and commercializing RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® for their intended uses in the targeted markets around the world. While these products have received regulatory approval and been launched and commercialized in the U.S. and certain other targeted markets, the products face substantial competition from existing products previously developed and commercialized both by GSK and by other competing pharmaceutical companies and can expect to face additional competition from new products that are discovered, developed and commercialized by the same pharmaceutical companies and other competitors going forward. For example, sales of Advair^®, GSK's approved medicine for both COPD and asthma, continue to be significantly greater than sales of RELVAR^®/BREO^® ELLIPTA^®, and GSK has indicated publicly that it intends to continue commercializing Advair^®.

        Many of the pharmaceutical companies competing in respiratory markets are international in scope with substantial financial, technical and personnel resources that permit them to discover, develop, obtain regulatory approval and commercialize new products in a highly efficient and low cost manner at competitive prices to consumers. In addition, many of these competitors have substantial commercial infrastructure that facilitates commercializing their products in a highly efficient and low cost manner at competitive prices to consumers. The market for products developed for treatment of COPD and asthma continues to experience significant innovation and reduced cost in bringing products to market over time. There can be no assurance that RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® will not be replaced by new products that are deemed more effective at lower cost to consumers. The ability of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® to succeed and achieve the anticipated level of sales depends on the commercial and development performance of GSK to achieve and maintain a competitive advantage over other products with the same intended use in the targeted markets.

        In addition, GSK made regulatory submissions for the approval of the closed triple combination therapy for COPD in the U.S. and EU at the end of 2016. If the closed triple combination (or MABA /FF) receives regulatory approval in either the U.S. or the EU, GSK's diligent efforts obligations regarding commercialization matters will have the objective of focusing on the best interests of patients and maximizing the net value of the overall portfolio of products under the GSK Agreements. Since GSK's commercialization efforts following such regulatory approval will be guided by a portfolio approach across products in which we have retained our full interest and also products in which we now have only a small portion of our former interest, GSK's commercialization efforts may have the effect of reducing the overall value of our remaining interests in the GSK Agreements in the future. If GSK prioritizes the closed triple product for COPD following regulatory approval, if any, we would only be entitled to a 15% economic interest in the future payments made by GSK under the GSK Agreements with respect to this product.

        If sales of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® are less than anticipated because of existing or future competition in the markets in which they are commercialized, including competition from existing and new products that are perceived as lower cost or more effective, our royalty payments will be less than anticipated, which in turn would harm our business and the price of our securities could fall.

We and GSK are developing UMEC/VI/FF (LAMA/LABA/ICS) and MABA/FF as potential triple combination treatments for COPD and, potentially, asthma. As a result of the Spin-Off, most of our economic rights in these programs were assigned to Theravance Biopharma. If these programs are successful and GSK and the respiratory market in general views triple combination therapy as significantly more beneficial than existing therapies, including RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®, our business could be harmed, and the price of our securities could fall.

        Under our LABA Collaboration Agreement with GSK, we and GSK are exploring various paths to create triple therapy respiratory medications. The use of triple therapy is supported by the GOLD ("Global initiative for chronic Obstructive Lung Disease") guidelines in high-risk patients with severe COPD and a high risk of exacerbations. One potential triple therapy path is the combination of UMEC/VI (two separate bronchodilators) and FF (an inhaled corticosteroid), to be administered via the ELLIPTA^® dry powder inhaler, referred to as UMEC/VI/FF or the "closed triple." Prior to the Spin-Off, we were entitled to receive 100% of any royalties payable under the GSK Agreements arising from sales of UMEC/VI/FF (as well as MABA and MABA/FF) if such products were successfully developed, approved and commercialized. In June 2016, we and GSK announced positive top-line results from the pivotal phase III FULFIL of the investigational once-daily 'closed' triple combination therapy (FF/UMEC/VI) in patients with COPD. GSK made regulatory submissions for the approval of the closed triple combination therapy for COPD in the U.S. and EU at the end of 2016. The commercial success of RELVAR^®/BREO^® ELLIPTA^® may be adversely effected if GSK or the respiratory markets view this closed triple combination or other combination therapies more beneficial. Furthermore, if the closed triple (or MABA /FF) receives regulatory approval in either the U.S. or the EU, GSK's diligent efforts obligations regarding commercialization matters will have the objective of focusing on the best interests of patients and maximizing the net value of the overall portfolio of products under the GSK Agreements. Since GSK's commercialization efforts following such regulatory approval will be guided by a portfolio approach across products in which we have retained our full interest and also products in which we now have only a small portion of our former interest, GSK's commercialization efforts may have the effect of reducing the overall value of our remaining interests in the GSK Agreements in the future. As a result of the transactions effected by the Spin-Off, however, we are now only entitled to receive 15% of any contingent payments and royalties payable by GSK from sales of FF/UMEC/VI (and MABA, and MABA/FF) while Theravance Biopharma receives 85% of those same payments.

In the event that Theravance Biopharma defaults or breaches the agreements we entered into with them in connection with the Spin-Off, our business and results of operations may be materially harmed.

        Upon the Spin-Off, our facility leases in South San Francisco, California were assigned to Theravance Biopharma. However, if Theravance Biopharma were to default on its lease obligations, we would be held liable by the landlord and thus, we have in substance guaranteed the lease payments for these facilities. We would also be responsible for lease-related payments including utilities, property taxes, and common area maintenance, which may be as much as the actual lease payments. As of December 31, 2016, the total remaining lease payments, which run through May 2020, were $21.7 million. In the event that Theravance Biopharma defaults on such obligations, our business and results of operations may be materially harmed.

        Under the terms of a separation and distribution agreement entered into between us and Theravance Biopharma, Theravance Biopharma will indemnify us from (i) all debts, liabilities and obligations transferred to Theravance Biopharma in connection with the Spin-Off (including its failure to pay, perform or otherwise promptly discharge any such debts, liabilities or obligations after the Spin-Off), (ii) any misstatement or omission of a material fact in its information statement filed with the SEC, resulting in a misleading statement and (iii) any breach by it of certain agreements entered into between the parties in connection with the Spin-Off. Theravance Biopharma's ability to satisfy these indemnities, if called upon to do so, will depend upon its future financial strength and if we are not able to collect on indemnification rights from Theravance Biopharma, our financial condition may be harmed.

We may not be able to utilize all of our net operating loss carryforwards.

        We have net operating loss carryforwards and other significant U.S. tax attributes that we believe could offset otherwise taxable income in the U.S. As a part of the overall Spin-Off transaction, the transfer of certain assets by us to Theravance Biopharma and our distribution of Theravance Biopharma ordinary shares resulted

Table of Contents

in taxable transfers pursuant to applicable provisions of the Internal Revenue Code of 1986, as amended (the "Code") and Treasury Regulations. The taxable gain recognized by us attributable to the transfer of certain assets to Theravance Biopharma will generally equal the excess of the fair market value of each asset transferred over our adjusted tax basis in such asset. Although we will not recognize any gain with respect to the cash we transferred to Theravance Biopharma, we may recognize substantial gain based on the fair market value of the other assets (other than cash) transferred to Theravance Biopharma. The determination of the fair market value of these assets is subjective and could be subject to adjustments or future challenge by the Internal Revenue Service ("IRS"), which could result in an increase in the amount of gain realized by us as a result of the transfer. Our U.S. federal income tax resulting from any gain recognized upon the transfer of our assets to Theravance Biopharma (including any increased U.S. federal income tax that may result from a subsequent determination of higher fair market values for the transferred assets), may be reduced by our net operating loss carryforward. The net operating loss carryforwards available in any year to offset our net taxable income will be reduced following a more than 50% change in ownership during any period of 36 consecutive months (an "ownership change") as determined under the Internal Revenue Code of 1986 (the "Code"). We have conducted an analysis to determine whether an ownership change had occurred since inception through December 31, 2015, and concluded that we had undergone two ownership changes in prior years. We have approximately $1.1 billion of net operating loss carryforward as of December 31, 2016. There may be certain annual limitations for utilization based on the above-described ownership change provisions. In addition, we may not be able to have sufficient future taxable income prior to their expiration because net operating losses have carryforward periods. Future changes in federal and state tax laws pertaining to net operating loss carryforwards may also cause limitations or restrictions from us claiming such net operating losses. If the net operating loss carryforwards become unavailable to us or are fully utilized, our future taxable income will not be shielded from federal and state income taxation absent certain U.S. federal and state tax credits, and the funds otherwise available for general corporate purposes would be reduced.

If any product candidates in any respiratory program partnered with GSK are not approved by regulatory authorities or are determined to be unsafe or ineffective in humans, our business will be adversely affected and the price of our securities could fall.

        The FDA must approve any new medicine before it can be marketed and sold in the U.S. Our partner GSK must provide the FDA and similar foreign regulatory authorities with data from preclinical and clinical studies that demonstrate that the product candidates are safe and effective for a defined indication before they can be approved for commercial distribution. GSK will not obtain this approval for a partnered 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 medicines in foreign countries, separate regulatory approvals must be obtained 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 country may make approval in other countries more difficult.

        Clinical studies involving product candidates partnered with GSK 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 or non-clinical studies. In addition, clinical and non-clinical studies of potential products often reveal that it is not possible or practical to continue development efforts for these product candidates. If these studies are substantially delayed or fail to prove the safety and effectiveness of product candidates in development partnered with GSK, GSK may not receive regulatory approval for such product candidates and our business and financial condition will be materially harmed and the price of our securities may fall.

        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 a 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 at the FDA's discretion. These laws, regulations, additional requirements and changes in interpretation could cause non-approval or further delays in the FDA's review and approval of any product candidates in any respiratory program partnered with GSK.

Even if product candidates in any respiratory program partnered with GSK receive regulatory approval, as is the case with RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®, commercialization of such products may be adversely affected by regulatory actions and oversight.

        Even if GSK receives regulatory approval for product candidates in any respiratory program partnered with GSK, this approval may include limitations on the indicated uses for which GSK can market the medicines or the patient population that may utilize the medicines, which may limit the market for the medicines or put GSK at a competitive disadvantage relative to alternative therapies. These restrictions make it more difficult to market the approved products.

        For example, at the joint meeting of the Pulmonary-Allergy Drugs Advisory Committee and Drug Safety and Risk Management Advisory Committee of the FDA regarding the sNDA for BREO^® ELLIPTA^® as a treatment for asthma, the advisory committee recommended that a large LABA safety trial with BREO^® ELLIPTA^® should be required in adults and in 12-17 year olds, similar to the ongoing LABA safety trials being conducted as an FDA Post-Marketing Requirement by each of the manufacturers of LABA containing asthma treatments.

        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 or GSK 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 GSK, including requiring it 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. GSK is 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 as well as governmental authorities in those foreign countries in which any of the product candidates in any respiratory program partnered with GSK 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. Any failure to maintain regulatory approval will limit GSK's ability to commercialize the product candidates in any respiratory program partnered with GSK, which would materially and adversely affect our business and financial condition and which may cause the price of our securities to fall.

We may not be successful in our efforts to expand our portfolio of royalty generating products.

        In the future, we may choose to acquire interests in or rights to one or more additional royalty generating products. However, we may be unable to license or acquire rights to suitable royalty generating products for a number of reasons. In particular, the licensing and acquisition of pharmaceutical product rights is a competitive area. Several more established companies are also pursuing strategies to license or acquire rights to royalty generating products. These established companies may have a competitive advantage over us. Other factors that

19

---

Table of Contents

may prevent us from licensing or otherwise acquiring rights to suitable royalty generating products include the following:

•

we may be unable to license or acquire the rights on terms that would allow us to make an appropriate return from the product;



•

companies that perceive us to be their competitors may be unwilling to assign or license their product rights to us; or



•

we may be unable to identify suitable royalty generating products.

        If we are unable to acquire or license rights to suitable royalty generating product candidates, our business may suffer.

        We are engaged in a continual review of opportunities to acquire income generating assets, whether royalty-based or otherwise, or to acquire companies that hold royalty or other income generating assets. We currently, and generally at any time, have acquisition opportunities in various stages of active review, including, for example, our engagement of consultants and advisors to analyze particular opportunities, technical, financial and other confidential information, submission of indications of interest and involvement as a bidder in competitive auctions or other processes for the acquisition of income generating assets. Many potential acquisition targets do not meet our criteria, and for those that do, we may face significant competition for these acquisitions from other financial investors and enterprises whose cost of capital may be lower than ours. Competition for future asset acquisition opportunities in our markets is competitive and we may be forced to increase the price we pay for such assets or face reduced potential acquisition opportunities. The success of any future income generating asset acquisitions is based on our ability to make accurate assumptions regarding the valuation, timing and amount of payments, which is highly complex and uncertain. The failure of any of these acquisitions to produce anticipated revenues may materially and adversely affect our financial condition and results of operations.

We have a significant amount of debt including Convertible Subordinated Notes and Non-Recourse Notes that are senior in capital structure and cash flow, respectively, to our common stockholders. Satisfying the obligations relating to our debt could adversely affect the amount or timing of distributions to our stockholders.

        As of December 31, 2016, we had approximately $728.2 million in total debt outstanding, comprised primarily of $241.0 million in principal that remains outstanding under our convertible subordinated notes, due 2023 (the "2023 Notes") and $487.2 million in principal that remains outstanding under our non-recourse fixed rate term notes due 2029 (the "2029 Notes") (the 2023 Notes and 2029 Notes hereinafter, the "Notes"). The 2023 Notes are unsecured debt and are not redeemable by us prior to the maturity date. Holders of the Notes may require us to purchase all or any portion of their Notes at 100% of their principal amount, plus any unpaid interest, upon a fundamental change. A fundamental change is generally defined to include a merger involving us, an acquisition of a majority of our outstanding common stock, and the change of a majority of our board without the approval of the board. In addition, to the extent we pursue and complete a monetization transaction or a transaction that modifies our corporate structure, the structure of such transaction may qualify as a fundamental change under the Notes, which could trigger the put rights of the holders of the Notes, in which case we would be required to use a portion of the net proceeds from such transaction to repurchase any Notes put to us. Our 2029 Notes have rights to 40% of all royalty payments received from GSK related to RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® until the notes are paid in full.

        Satisfying the obligations of this debt could adversely affect the amount or timing of any distributions to our stockholders. We may choose to satisfy repurchase, or refinance this debt through public or private equity or debt financings if we deem such financings available on favorable terms. If any or all of the 2023 Notes are not converted into shares of our common stock before the maturity date, we will have to pay the holders the full aggregate principal amount of the Notes then outstanding. If the 2029 Notes are not refinanced or paid in full, then they will receive 40% of all future economics associated with RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® until the notes are paid in full. Any of the above payments could have a material adverse effect on our cash position. If we fail to satisfy these obligations, it may result in a default under the indenture,

which could result in a default under certain of our other debt instruments, if any. Any such default would harm our business and the price of our securities could fall.

If we lose key management personnel, or if we fail to retain our key employees, our ability to manage our business will be impaired.

        We have a small management team and very few employees. We are highly dependent on principal members of our management team and a small group of key employees 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 business operations, which may cause the price of our securities to fall.

We rely and will continue to rely on outsourcing arrangements for many of our activities, including financial reporting and accounting and human resources.

        As of December 31, 2016, we had only 14 full-time employees and, as a result, we rely, and expect to continue to rely, on outsourcing arrangements for a significant portion of our activities, including financial reporting and accounting and human resources, as well as for certain functions as a public company. We may have limited control over these third parties and we cannot guarantee that they will perform their obligations in an effective and timely manner.

If we fail to maintain proper and effective internal control over financial reporting or if the interpretations, estimates or judgments utilized in preparing our financial statements prove to be incorrect, our operating results and our ability to operate our business could be harmed.

        The Sarbanes-Oxley Act requires, among other things, that we establish and maintain effective internal control over financial reporting and disclosure controls and procedures. Under the SEC's current rules, we are required to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our independent registered public accounting firm is also required to report on our internal control over financial reporting. Our testing and our independent registered public accounting firm's testing may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses and render our internal control over financial reporting ineffective. We have and expect to continue to incur substantial accounting and auditing expense and to expend significant management time in complying with the requirements of Section 404. If we are not able to maintain compliance with the requirements of Section 404 in a timely manner, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to investigations or sanctions by the SEC, FINRA, NASDAQ or other regulatory authorities. In addition, we could be required to expend significant management time and financial resources to correct any material weaknesses that may be identified or to respond to any regulatory investigations or proceedings.

        We are also subject to complex tax laws, regulations, accounting principles and interpretations thereof. The preparation of our financial statements requires us to interpret accounting principles and guidance and make estimates and judgments 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 generated and expenses incurred during the reporting periods. Our interpretations, estimates and judgments are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for the preparation of our financial statements. GAAP presentation is subject to interpretation by the SEC, the Financial Accounting Standards Board and various other bodies formed to interpret and create appropriate accounting principles and guidance. In the event that one of these bodies disagrees with our accounting recognition, measurement or disclosure or any of our accounting interpretations, estimates or assumptions, it may have a significant effect on our reported results and may retroactively affect

21

previously reported results. The need to restate our financial results could, among other potential adverse effects, result in us incurring substantial costs, affect our ability to timely file our periodic reports until such restatement is completed, divert the attention of our management and employees from managing our business, result in material changes to our historical and future financial results, result in investors losing confidence in our operating results, subject us to securities class action litigation, and cause our stock price to decline.

As we continue to develop our business, our mix of assets and our sources of income may require that we register with the SEC as an "investment company" in accordance with the Investment Company Act of 1940.

        We have not been and have no current intention to register as an "investment company" under the Investment Company Act of 1940, or the 40 Act, because we believe the nature of our assets and the sources of our income currently exclude us from the definition of an investment company pursuant to Sections (3)(a)(1)(A), (3)(a)(1)(C) under the 40 Act and Rule 270.3a-1 of Title 17 of the Code of Federal Regulations. Accordingly, we are not currently subject to the provisions of the 40 Act, such as compliance with the 40 Act's registration and reporting requirements, capital structure requirements, affiliate transaction restrictions, conflict of interest rules, requirements for disinterested directors, and other substantive provisions. Generally, to avoid being a company that is an "investment company" under the 40 Act, it must both: (a) not be or hold itself out as being engaged primarily in the business of investing, reinvesting or trading in securities, and (b) either (i) not be engaged or propose to engage in the business of investing in securities or own or propose to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis or (ii) not have more than 45% of the value of its total assets (exclusive of Government securities and cash items) consist of or more than 45% of its net income after taxes (for the last four fiscal quarters combined) be derived from securities. In addition, we would not be an "investment company" if an exception, exemption, or safe harbor under the 40 Act applies.

        We monitor our assets and income for compliance with the tests under the 40 Act and seek to conduct our business activities to ensure that we do not fall within its definitions of "investment company." If we were to become an "investment company" and be subject to the strictures of the 40 Act, the restrictions imposed by the 40 Act would likely require changes in the way we do business and add significant administrative burdens to our operations. In order to ensure that we do not fall within the 40 Act, we may need to take various actions which we might otherwise not pursue. These actions may include restructuring the Company and/or modifying our mixture of assets and income.

        Specifically, our mixture of debt vs. royalty assets is important to our classification as an "investment company" or not. In this regard, while we currently believe that none of the definitions of "investment company" apply to us, we may in the future rely on an exception under the 40 Act provided by Section 3(c)(5)(A). To qualify for Section 3(c)(5)(A), as interpreted by the staff of the SEC, we would be required to have at least 55% of our total assets in "notes, drafts, acceptances, open accounts receivable, and other obligations representing part or all of the sales price of merchandise, insurance, and services" (or Qualifying Assets). In a no-action letter issued to Royalty Pharma on August 13, 2010, the staff stated that royalty interests are Qualifying Assets under this exception. If the SEC or its staff in the future adopts a contrary interpretation or otherwise restricts the conclusions in the staff's no-action letter such that our royalty interests are no longer Qualifying Assets for purposes of Section 3(c)(5)(A), we could be required to register under the 40 Act.

        The rules and interpretations of the SEC and the courts, relating to the definition of "investment company" are highly complex in numerous respects. While we currently intend to conduct our operations so that we will not be deemed an investment company, we can give no assurances that we will not determine it to be in the Company's and our stockholders' interest to register as an "investment company", not be deemed an "investment company" and not be required to register under the 40 Act.

Prolonged economic uncertainties or downturns, as well as unstable market, credit and financial conditions, may exacerbate certain risks affecting our business and have serious adverse consequences on our business.

        The global economic downturn and market instability has made the business climate more volatile and more costly. For instance, the United Kingdom's recent decision to exit the European Union ("Brexit") has provided further uncertainty and potential volatility around European currencies. These economic conditions,

22

---

Table of Contents

and uncertainty as to the general direction of the macroeconomic environment, are beyond our control and may make any necessary debt or equity financing more difficult, more costly, and more dilutive. While we believe we have adequate capital resources to meet current working capital and capital expenditure requirements, a lingering economic downturn or significant increase in our expenses could require additional financing on less than attractive rates or on terms that are excessively dilutive to existing stockholders. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our stock price and could require us to delay or abandon clinical development plans.

        Sales of our partnered products will be dependent, in large part, on reimbursement from government health administration authorities, private health insurers, distribution partners and other organizations. As a result of negative trends in the general economy in the U.S. or other jurisdictions in which we may do business, these organizations may be unable to satisfy their reimbursement obligations or may delay payment. In addition, federal and state health authorities may reduce Medicare and Medicaid reimbursements, and private insurers may increase their scrutiny of claims. A reduction in the availability or extent of reimbursement could negatively affect our or our partners' product sales and revenue.

        In addition, we rely on third parties for several important aspects of our business. During challenging and uncertain economic times and in tight credit markets, there may be a disruption or delay in the performance of our third party contractors, suppliers or partners. If such third parties are unable to satisfy their commitments to us, our business and results of operations would be adversely affected.

Risks Related to our Alliance with GSK

Because all our current and projected revenues are derived from products under the GSK Agreements, disputes with GSK could harm our business and cause the price of our securities to fall.

        All of our current and projected revenues are derived from products under the GSK Agreements. Any action or inaction by either GSK or us that results in a material dispute, allegation of breach, litigation, arbitration, or significant disagreement between the parties may be interpreted negatively by the market or by our investors, could harm our business and cause the price of our securities to fall. Examples of these kinds of issues include but are not limited to non-performance of contractual obligations and allegations of non-performance, disagreements over the relative marketing and sales efforts for our partnered products and other GSK respiratory products, disputes over public statements, and similar matters. In addition, while we obtained GSK's consent to the Spin-Off as structured, GSK could decide to challenge various aspects of our post-Spin-Off operation of TRC, the limited liability company jointly owned by us and Theravance Biopharma as violating or allowing it to terminate the GSK Agreements. Although we believe our operation of TRC fully complies with the GSK Agreements and applicable law, there can be no assurance that we would prevail against any such claims by GSK. Moreover, regardless of the merit of any claims by GSK, we may incur significant cost and diversion of resources in defending them. In addition, any market or investor uncertainty about the respiratory programs partnered with GSK or the enforceability of the GSK Agreements could result in significant reduction in the market price of our securities and other material harm to our business.

Because GSK is a strategic partner as well as a significant stockholder, it may take actions that in certain cases are materially harmful to both our business or to our other stockholders.

        Although GSK beneficially owns approximately 29.3% of our outstanding common stock as of February 24, 2017, it is also a strategic partner with rights and obligations under the GSK Agreements that cause its interests to differ from the interests of us and our other stockholders. In particular, GSK has a substantial respiratory product portfolio in addition to the partnered products that are covered by the GSK Agreements. GSK may make respiratory product portfolio decisions or statements about its portfolio which may be, or may be perceived to be, harmful to the respiratory products partnered with us. For example, GSK could promote its non-GSK/Innoviva respiratory products or a partnered product for which we are entitled to receive a lower percentage of royalties, delay or terminate the development or commercialization of the respiratory programs covered by the GSK Agreements, or take other actions, such as making public statements, that have a negative effect on our stock price. In this regard and by way of example, sales of Advair^®, GSK's approved medicine for both COPD and asthma, continue to be significantly greater than sales of RELVAR^®/BREO^® ELLIPTA^®, and

23

---

Table of Contents

GSK has indicated publicly that it intends to continue commercializing Advair^®. Also, given the potential future royalty payments GSK may be obligated to pay under the GSK Agreements, GSK may seek to acquire us to reduce those payment obligations. The timing of when GSK may seek to acquire us could potentially be when it possesses information regarding the status of drug programs covered by the GSK Agreements that has not been publicly disclosed and is not otherwise known to us. As a result of these differing interests, GSK may take actions that it believes are in its best interest but which might not be in the best interests of either us or our other stockholders. In addition, upon regulatory approval of the closed triple combination or a MABA/ICS in either the U.S. or the EU, GSK's diligent efforts obligations as to commercialization matters under the GSK Agreements will have the objective of focusing on the best interests of patients and maximizing the net value of the overall portfolio of products under the GSK Agreements. Since GSK's commercialization efforts following such regulatory approval will be guided by a portfolio approach across products in which we have retained our full interest and also products in which we now have only a portion of our former interest, GSK's commercialization efforts may have the effect of reducing the overall value of our remaining interests in the products covered by the GSK Agreements in the future. In addition, following the expiration of our governance agreement with GSK in September 2015, GSK is no longer subject to the restrictions thereunder regarding the voting of the shares of our common stock owned by it.

GSK has also indicated to us that it believes its consent may be required before we can engage in certain royalty monetization transactions with third parties, which may inhibit our ability to engage in these transactions.

        In the course of our discussions with GSK concerning the Spin-Off of Theravance Biopharma, GSK indicated to us that it believes that its consent may be required before we can engage in certain transactions designed to monetize the future value of royalties that may be payable to us from GSK under the GSK Agreements. GSK has informed us that it believes that there may be certain covenants included in these types of transactions that might violate certain provisions of the GSK Agreements. Although we believe that we can structure royalty monetization transactions in a manner that fully complies with the requirements of the GSK Agreements without GSK's consent, a third party in a proposed monetization transaction may nonetheless insist that we obtain GSK's consent for the transaction or re-structure the transaction on less favorable terms. We have obtained GSK's agreement that (i) we may grant certain pre-agreed covenants in connection with monetization of our interests in RELVAR^®/BREO^® ELLIPTA^®, ANORO^® ELLIPTA^® and vilanterol monotherapy and portions of our interests in TRC, and (ii) it will not unreasonably withhold its consent to our requests to grant other covenants, provided, among other conditions, that in each case, the covenants are not granted in favor of pharmaceutical or biotechnology company with a product either being developed or commercialized for the treatment of respiratory disease. If we seek GSK's consent to grant covenants other than pre-agreed covenants, we may not be able to obtain GSK's consent on reasonable terms, or at all. If we proceed with a royalty monetization transaction that is not otherwise covered by the GSK Agreement without GSK's consent, GSK could request that its consent be obtained or seek to enjoin or otherwise challenge the transaction as violating or allowing it to terminate the GSK Agreements. Regardless of the merit of any claims by GSK, we would incur significant cost and diversion of resources in defending against GSK's claims or asserting our own claims and GSK may seek concessions from us in order to provide its consent. Any uncertainty about whether or when we could engage in a royalty monetization transaction, the potential impact on the enforceability of the GSK Agreements or the loss of potential royalties from the respiratory programs partnered with GSK, could impair our ability to pursue a return of capital strategy for our stockholders ahead of our receipt of significant royalties from GSK, result in significant reduction in the market price of our securities and cause other material harm to our business.

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 24, 2017, GSK beneficially owned approximately 29.3% of our outstanding common stock. As such, 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. The procedures previously governing and restricting GSK offers to our stockholders to acquire outstanding voting stock and the restrictions regarding the voting of

24

Table of Contents

shares of our common stock owned by it terminated upon the expiration of the governance agreement in September 2015. 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.

GSK's significant ownership position may deter or prevent efforts by other companies to acquire us, which could prevent our stockholders from realizing a control premium.

        As of February 24, 2017, GSK beneficially owned approximately 29.3% of our outstanding common stock. As a result of GSK's significant ownership, 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.

        GSK is not subject to any contractual restrictions with us 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. Sales by GSK of a substantial number of shares, or the expectation of such sales, could cause a significant reduction in the market price of our common stock.

Risks Related to Legal and Regulatory Uncertainty

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

        Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented, declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which are necessary to build name and brand recognition among potential partners or customers in our markets of interest. At times, competitors may adopt trademarks or trade names similar to ours, thereby impeding our ability to build name and brand identity and possibly leading to market confusion. In addition, there could be potential trademark or trade name infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. There was also a risk that if there is confusion in the marketplace, the reputation, performance and/or actions of such third parties may negatively impact our stock price and our business. We therefore have, as of January 2016, adopted a new brand, Innoviva. Over the long term, if we are unable to establish name and brand recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. If we fail to promote and maintain our brand successfully, or if we incur substantial expenses in an unsuccessful attempt to promote and maintain our brand, our business may be harmed.

If the efforts of our partner, GSK, to protect the proprietary nature of the intellectual property related to products in any respiratory program partnered with GSK are not adequate, the future commercialization of any such product could be delayed, limited or prevented, which would materially harm our business and the price of our securities could fall.

        To the extent the intellectual property protection of products in any respiratory program partnered with GSK are successfully challenged or encounter problems with the U.S. Patent and Trademark Office or other comparable agencies throughout the world, the commercialization of these products could be delayed, limited or prevented. Any challenge to the intellectual property protection of a late-stage development asset or approved product arising from any respiratory program partnered with GSK could harm our business and cause the price of our securities to fall.

        Our commercial success depends in part on products in any respiratory program partnered with GSK not infringing the patents and proprietary rights of third parties. Third parties may assert that these products are using their proprietary rights without authorization. In addition, third parties may obtain patents in the future and claim that use of GSK's technologies infringes upon these patents. Furthermore, parties making claims against GSK may obtain injunctive or other equitable relief, which could effectively block GSK's ability to further develop or commercialize one or more of the product candidates or products in any respiratory program partnered with GSK.

        In the event of a successful claim of infringement against GSK, it 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, GSK may need to obtain licenses from third parties to advance its research or allow commercialization of the products. GSK may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, GSK would be unable to further develop and commercialize one or more of the products, which could harm our business significantly. In addition, in the future GSK could be required to initiate litigation to enforce its proprietary rights against infringement by third parties. Prosecution of these claims to enforce its rights against others would involve substantial litigation expenses. If GSK fails to effectively enforce its proprietary rights related to our partnered respiratory programs against others, our business will be harmed, and the price of our securities could fall.

Risks Related to Ownership of our Common Stock

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

        The price of our securities has been volatile and may continue to be so. Between January 1, 2016 and December 31, 2016, the high and low sales prices of our common stock as reported on The NASDAQ Global Select Market varied between $13.77 and $8.23 per share. 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 several 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:

•

any adverse developments or results or perceived adverse developments or results with respect to the commercialization of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® with GSK, including, without limitation, if payor coverage is lower than anticipated or if sales of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® are less than anticipated because of pricing pressure in the respiratory markets targeted by our partnered products or existing or future competition in the markets in which they are commercialized, including competition from existing and new products that are perceived as lower cost or more effective, and our royalty payments are less than anticipated;

any adverse developments or results or perceived adverse developments or results with respect to the on-going development of FF/VI with GSK, including, without limitation, any difficulties or delays encountered with the regulatory path for FF/VI or any indication from clinical or non-clinical studies, including the large Phase 3b program, that FF/VI is not safe or efficacious or does not sufficiently differentiate itself from alternative therapies;



•

any adverse developments or results or perceived adverse developments or results with respect to the on-going development of UMEC/VI with GSK, including, without limitation, any difficulties or delays encountered with regard to the regulatory path for UMEC/VI, any indication from clinical or non-clinical studies that UMEC/VI is not safe or efficacious;



•

any adverse developments or perceived adverse developments in the field of LABAs, including any change in FDA (or comparable foreign regulatory authority) policy or guidance (such as the

We may be unable to or elect not to continue returning capital to our stockholders

        We have a corporate goal of returning capital to stockholders and paid quarterly dividends during the third and fourth quarters of 2014 and during the first three quarters of 2015. In October 2015, we announced the acceleration of our capital return plan with an up to $150 million share repurchase program approved by our Board of Directors effective through December 31, 2016, which replaced our quarterly dividends. As of December 31, 2016, we had repurchased an aggregate of $103.7 million under the share repurchase program through a combination of a tender offer and open market purchases and $11.6 million of our 2023 Notes. In February 2017, we announced a new capital return plan, the 2017 Capital Return Plan. The 2017 Capital Return Plan authorizes a combination of repurchases of stock and/or repurchases, redemptions or prepayments of debt up to $150 million, through tender offers, open market purchases, private transactions, exchange offers or other means through December 31, 2017. The 2017 Capital Return Plan is expected to be funded using our working capital. Our announcement of this or future capital return programs does not obligate us to repurchase any specific dollar amount of debt or equity or number of shares of common stock.

Table of Contents

        The payment of, or continuation of, capital returns to stockholders is at the discretion of our Board of Directors and is dependent upon our financial condition, results of operations, capital requirements, general business conditions, tax treatment of capital returns, potential future contractual restrictions contained in credit agreements and other agreements and other factors deemed relevant by our board of directors. Future capital returns may also be affected by, among other factors: our views on potential future capital requirements for investments in acquisitions and our working capital and debt maintenance requirements; legal risks; stock or debt repurchase programs; changes in federal and state income tax laws or corporate laws; and changes to our business model. Our capital return programs may change from time to time, and we cannot provide assurance that we will continue to provide any particular amounts. A reduction, suspension or change in our capital return programs could have a negative effect on our stock price.

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

        As of February 24, 2017, GSK beneficially owned approximately 29.3% of our outstanding common stock and our directors, executive officers and investors affiliated with these individuals beneficially owned approximately 2.3% of our outstanding common stock. Based on our review of publicly available filings as of February 24, 2017, our four largest stockholders other than GSK collectively owned approximately 47.0% of our outstanding common 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. Following the expiration of the governance agreement in September 2015, GSK is no longer subject to the restrictions thereunder regarding the voting of the shares of our common stock owned by it.

Anti-takeover provisions in our charter and bylaws 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:

•

requiring supermajority stockholder voting to effect certain amendments to our Certificate of Incorporation and Bylaws;



•

restricting the ability of stockholders to call special meetings of stockholders;



•

prohibiting stockholder action by written consent; and



•

establishing advance notice requirements for nominations for election to the Board or for proposing matters that can be acted on by stockholders at meetings.

        In addition, some provisions of Delaware law may also discourage, delay or prevent someone from acquiring us or merging with us.

Purchases of Equity Securities by the Issuer

        On October 28, 2015, we announced the acceleration of our capital return plan with an up to $150 million share repurchase program effective through the end of 2016 approved by our Board of Directors (the "2016 Share Repurchase Program"). In February 2017, we announced a new capital return plan, the 2017 Capital Return Plan. The 2017 Capital Return Plan authorizes a combination of repurchases of stock and/or repurchases, redemptions or prepayments of debt up to $150 million, through tender offers, open market purchases, private transactions, exchange offers or other means through December 31, 2017. The 2017 Capital Return Plan is expected to be funded using our working capital. We are not obligated to repurchase any specific dollar amount of debt or equity or number of shares of common stock under the 2017 Capital Return Plan. We will determine when, if and how to proceed with any repurchase transactions under the program, as well as the amount of any such repurchase transactions, based upon, among other things, our evaluation of our liquidity and capital needs (including for strategic and other opportunities), our business, results of operations, and financial position and prospects, general financial, economic and market conditions, prevailing market prices for shares of our common stock, corporate, regulatory and legal requirements, and other conditions and factors deemed relevant by our management and Board of Directors from time to time. Our 2017 Capital Return Plan may be suspended or discontinued at any time.

Management Overview

        Innoviva, Inc. is focused on bringing compelling new medicines to patients in areas of unmet need by leveraging its significant expertise in the development, commercialization and financial management of bio-pharmaceuticals, to maximize the commercial potential of its respiratory assets partnered with Glaxo Group Limited ("GSK"), including RELVAR^®/BREO^® ELLIPTA^® (fluticasone furoate/ vilanterol, "FF/VI") and ANORO^® ELLIPTA^® (umeclidinium bromide/ vilanterol, "UMEC/VI"). Under the Long-Acting Beta2 Agonist ("LABA") Collaboration Agreement and the Strategic Alliance Agreement with GSK (referred to herein collectively as the "GSK Agreements"), we are entitled to receive royalties from GSK on sales of RELVAR^®/BREO^® ELLIPTA^® as follows: 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. For other products combined with a LABA from the LABA collaboration, such as ANORO™ ELLIPTA™, royalties are upward tiering and range from 6.5% to 10%. Innoviva is also entitled to 15% of any future payments made by GSK under its agreements originally entered into with us, and since assigned to Theravance Respiratory Company, LLC ("TRC"). In June 2014, we spun-off our research and development activities by distributing the outstanding shares of Theravance Biopharma, Inc. ("Theravance Biopharma") on a pro-rata basis to our stockholders (the "Spin-Off"), which resulted in Theravance Biopharma becoming an independent, publicly traded company.

        We have designed our company structure and organization to be tailored to our focused activities of managing our respiratory assets with GSK, the commercial and developmental obligations associated with the GSK Agreements, intellectual property, licensing operations, business development activities and providing for certain essential reporting and management functions of a public company. As of December 31, 2016, we had 14 employees. Our revenues consist of royalties and potential milestone payments, if any, from our respiratory partnership agreements with GSK.

Financial Highlights

        In the year ended December 31, 2016, our net income from operations was $59.5 million, an improvement of $78.3 million from a net loss from continuing operations of $18.8 million in the year ended December 31, 2015, primarily due to an increase in net royalty revenue. Cash, cash equivalents, and marketable securities, totaled $150.4 million on December 31, 2016, a decrease of $36.9 million from December 31, 2015. The decrease was due primarily to the repurchases of common stock of $78.1 million, repurchases of our 2023 Notes of $11.6 million, payments on principal of our 2029 Notes of $6.8 million and net purchases of marketable securities of $4.3 million. These outflows were partially offset by cash provided by operating activities of $61.0 million.

Capital Return Plans

        In October 2015, we announced the acceleration of our capital return plan with an up to $150 million share repurchase program effective through the end of 2016, the 2016 Share Repurchase Program. In February 2017, we announced a new capital return plan, the 2017 Capital Return Plan. The 2017 Capital Return Plan authorizes a combination of repurchases of stock and/or repurchases, redemptions or prepayments of debt up to $150 million, through tender offers, open market purchases, private transactions, exchange offers or other means through December 31, 2017. The 2017 Capital Return Plan is expected to be funded using our working capital. We are not obligated to repurchase any specific dollar amount of debt or equity or number of shares of common stock under the 2017 Capital Return Plan. We will determine when, if and how to proceed with any repurchase transactions under the program, as well as the amount of any such repurchase transactions, based upon, among other things, our evaluation of our liquidity and capital needs (including for strategic and other opportunities), our business, results of operations, and financial position and prospects, general financial, economic and market conditions, prevailing market prices for shares of our common stock, corporate, regulatory and legal requirements, and other conditions and factors deemed relevant by our management and Board of Directors from time to time. Our 2017 Capital Return Plan may be suspended or discontinued at any time. There can be no assurance as to the actual volume of any debt or share repurchases in any given period or over the term of the program or as to the manner or terms of any such transactions.

        From January 1, 2016 to December 31, 2016, we purchased 7,201,448 shares of our common stock at an average purchase price of $10.84 per share for a total value of approximately $78.1 million in the open market pursuant to the 2016 Share Repurchase Program. Overall, under the 2016 Share Repurchase Program, we purchased 9,877,684 shares of our common stock at an average purchase price of $10.50 per share for a total value of approximately $103.7 million.

Repurchases of Notes Payable

        During the year ending December 31, 2016, we retired a portion of our 2023 Notes with a face value of $14.1 million and carrying value of $13.9 million by way of open market purchases. The 2023 Notes were purchased for a total settlement price of $11.6 million resulting in a gain of $2.3 million. As a result of the partial retirement of our 2023 Notes, we entered into partial termination agreements of our capped call option transaction and received $0.6 million from the counterparty.

Collaborative Arrangements with GSK

LABA Collaboration

        In November 2002, we entered into our LABA Collaboration Agreement with GSK to develop and commercialize once-daily LABA products for the treatment of chronic obstructive pulmonary disease ("COPD") and asthma. The collaboration has developed two combination products: (1) RELVAR^®/BREO^® ELLIPTA^® (FF/VI) (BREO^® ELLIPTA^® is the proprietary name in the U.S. and Canada and RELVAR^® ELLIPTA^® is the proprietary name outside the U.S. and Canada), a once-daily combination medicine consisting of a LABA, vilanterol (VI), and an inhaled corticosteroid (ICS), fluticasone furoate (FF) and (2) ANORO^® ELLIPTA^® (UMEC/VI), a once-daily medicine combining a long-acting muscarinic antagonist ("LAMA"), umeclidinium bromide (UMEC), with a LABA, VI.

Table of Contents

        As a result of the launch and approval of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® in the U.S., Japan and Europe, we paid milestone fees to GSK totaling $220.0 million during the year ended December 31, 2014. Although we have no further milestone payment obligations to GSK pursuant to the LABA Collaboration Agreement, we continue to have ongoing participation as part of the collaboration, including joint steering and joint project committees that are expected to continue over the life of the agreement. The milestone fees paid to GSK were recognized as capitalized fees paid to a related party, which are being amortized over their estimated useful lives commencing upon the commercial launch of the products.

        We are entitled to receive royalties from GSK on sales of RELVAR^®/BREO^® ELLIPTA^® as follows: 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion. For other products combined with a LABA from the LABA collaboration, such as ANORO™ ELLIPTA™, royalties are upward tiering and range from 6.5% to 10%.

2004 Strategic Alliance

        In March 2004, we entered into the Strategic Alliance Agreement with GSK where 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. 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 Innoviva-discovered preclinical MABA compounds (the "Additional MABAs"). GSK is responsible for funding all future development, manufacturing and commercialization activities for product candidates in that program. As a result of the Spin-Off, we are only entitled to receive 15% of any contingent payments and royalties payable by GSK from sales of FF/UMEC/VI (and MABA, and MABA/FF) while Theravance Biopharma receives 85% of those same payments. See PART I, ITEM 1. BUSINESS — Our Relationship with GSK — 2004 Strategic Alliance, for more detail regarding the royalties payable by GSK under this agreement, if any.

Critical Accounting Policies and Estimates

        Our management's discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). 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 as of the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management's judgments and estimates.

Revenue Recognition

        Revenue is recognized when the four basic criteria of revenue recognition are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. Where the revenue recognition criteria are not met, we defer the recognition of revenue by recording deferred revenue until such time that all criteria are met.

Collaborative Arrangements and Multiple Element Arrangements

        We generate revenue from collaboration and license agreements for the development and commercialization of product candidates. Under the GSK agreements, revenue from non-refundable, upfront fees and development contingent payments were recognized ratably over the expected term of our performance of research and development services under the agreements. These upfront or contingent payments received, pending recognition as revenue, were recorded as deferred revenue and recognized over the estimated performance periods. We recognize royalty revenue on licensee net sales of products with respect to which we

35

---

Table of Contents

have royalty rights in the period in which the royalties are earned and reported to us and collectability is reasonably assured. Royalty revenue earned is reduced by amortization expense resulting from the fees paid to GSK, which were recognized as capitalized fees paid to a related party.

        Under the GSK Agreements, we recognized net revenue of $133.6 million, $53.9 million and $8.4 million for the years ended December 31, 2016, 2015 and 2014, respectively. The remaining deferred revenue under the GSK Strategic Alliance Agreement is $3.1 million as of December 31, 2016. Any change in the estimated performance period, which is predominantly based on GSK's development timeline, will not have a significant impact on the results of operations, except for a change in estimated performance period resulting from the termination of the MABA program that would result in immediate recognition of the deferred revenue.

Capitalized Fees paid to a Related Party

        We capitalize fees paid to licensors related to agreements for approved products or commercialized products ("Capitalized Fees"). Our gross Capitalized Fees of $220.0 million as of December 31, 2016 consist of registrational and launch-related to milestone fees paid to GSK. We capitalized these fees as capitalized fees paid to a related party and amortize these Capitalized Fees on a straight-line basis over their estimated useful lives upon the commercial launch of the products. The estimated useful lives of these Capitalized Fees are based on a country-by-country and product-by-product basis, as the later of the expiration or termination of the last patent right covering the compound in such product in such country and 15 years from first commercial sale of such product in such country, unless the agreement is terminated earlier. Consistent with our policy for classification of costs under the research and development collaborative arrangements, the amortization of these Capitalized Fees is recognized as a reduction of royalty revenue. Amortization expense for the years ended December 31, 2016, 2015 and 2014 were $13.8 million, $13.8 million and $11.1 million, respectively. The remaining estimated amortization expense is $13.8 million for each of the years from 2017 to 2021 and $111.4 million thereafter.

        We review our Capitalized Fees for impairment on a product-by-product basis for each major geographic area when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The recoverability of Capitalized Fees is measured by comparing the asset's carrying amount to the expected undiscounted future cash flows that the asset is expected to generate. The determination of recoverability typically requires various estimates and assumptions, including estimating the useful life over which cash flows will occur, their amount, and the asset's residual value, if any. We derive the required cash flow estimates from near-term forecasted product sales and long-term projected sales in the corresponding market. Based upon our analyses, no impairment charges have been recorded on the Capitalized Fees as of December 31, 2016.

Fair Value of Stock-Based Compensation Awards

        We use the Black-Scholes-Merton option pricing model to estimate the fair value of options as of the date of grant. The Black-Scholes-Merton 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, "Share Based Payment," for the expected option term. We use our historical volatility to estimate expected stock price volatility. The estimated fair value of the option is expensed on a ratable basis over the expected term of the grant.

        We determine the fair value of RSUs and RSAs based on the fair market values of the underlying stock on the dates of grant. The fair value of service based RSUs and RSAs is expensed on a ratable or straight-line basis over the expected term of the vesting. The fair value of performance-contingent RSUs and RSAs is expensed using an accelerated method over the requisite service period based on management's best estimate as to whether it is probable that the shares awarded are expected to vest. We assess the probability of the performance indicators being met on a continuous basis. The grant date fair value of the RSUs and RSAs with a market condition is determined using a Monte Carlo valuation model and the compensation expense is recognized over the implied service period.

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

Amortization of Debt Issuance Costs from Non-recourse Notes Payable, due 2029

        In April 2014, we entered into certain note purchase agreements relating to the private placement of $450.0 million aggregate principal amount of non-recourse 9% fixed rate term notes due 2029 (the "2029 Notes") issued by our wholly-owned subsidiary. The 2029 Notes are secured exclusively by a security interest in a segregated bank account established to receive 40% of royalties due to us under the LABA Collaboration with GSK commencing on April 1, 2014 and ending upon the earlier of full repayment of principal or May 15, 2029. The funds in the segregated bank account can only be used to make principal and interest payments on the 2029 Notes.

        The 2029 Notes bear an annual interest rate of 9%, with interest and principal paid quarterly beginning November 15, 2014. The 2029 Notes may be redeemed at any time prior to maturity, in whole or in part, at specified redemption premiums. Prior to May 15, 2016, in the event that the specified portion of royalties received in a quarter was less than the interest accrued for the quarter, the principal amount of the 2029 Notes was increased by the interest shortfall amount for that period.

        In connection with the issuance of the 2029 Notes, we incurred approximately $15.3 million in transaction costs, which are amortized to interest expense over the estimated life of the 2029 Notes based on the effective interest method. Since the principal and interest payments on the 2029 Notes are based on royalties from product sales, which vary from quarter to quarter, the 2029 Notes may be repaid prior to the final maturity date in 2029. To the extent that the interest or principal payments are greater or less than our initial estimates or the timing of such payments is materially different than our original estimates, we will prospectively adjust the amortization of the debt issuance costs. There are a number of factors that could materially affect the amount and timing of the royalty payments due to us under the LABA Collaboration with GSK, most of which are not within our control. Such factors include, but are not limited to, the competitive landscape for approved products and developing therapies that compete with our partnered products, the ability of patients to be able to afford our partnered products, the size of the market for our partnered products, safety concerns in the marketplace for respiratory therapies in general and with our partnered products in particular, decisions as to the timing of product launches, pricing and discounts, and other events or circumstances that result in reduced royalty payments, all of which would result in an impact to the amount of debt issuance costs amortized.

Results of Operations

Net Revenue

        Total net revenue from continuing operations, as compared to the prior years, was as follows:

37

---

Table of Contents

        Total net revenue increased for the year ended December 31, 2016, compared to the year ended December 31, 2015. The increases were primarily due to growth in prescriptions and market share for both RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®. The revenue growth during the year ended December 31, 2016 as compared to the year ended December 31, 2015 may not be indicative of our future revenue growth, if any.

        Total net revenue increased for the year ended December 31, 2015, compared to the year ended December 31, 2014. The increases were primarily due to higher sales of RELVAR^®/BREO^® ELLIPTA^®, ANORO^® ELLIPTA^® not having been commercially launched until April 2014 and the approval in April 2015 of BREO^® ELLIPTA^® (FF/VI) as a once-daily inhaled treatment of asthma in patients aged 18 years and older in the U.S.

Research & Development

        Research & Development ("R&D") expenses from continuing operations, as compared to the prior years, were as follows:

        R&D expenses decreased for the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to reduced activities related to the late-stage partnered respiratory assets with GSK.

        R&D expenses from continuing operations decreased for the year ended December 31, 2015 compared to the year ended December 31, 2014 primarily due to fewer costs incurred and due to higher stock-based compensation in the year ended December 31, 2014. Stock-based compensation expense was higher during the year ended December 31, 2014 due to the achievement of performance conditions under a specified long-term retention and incentive equity awarded to certain employees in the year ended December 31, 2011.

General & Administrative

        General and administrative expenses from continuing operations, as compared to the prior years, were as follows:

        General and administrative expenses increased in the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to the recognition of stock-based compensation expenses related to pre-Spin-Off legacy performance-contingent RSAs and higher employee costs.

        General and administrative expenses from continuing operations decreased in the year ended December 31, 2015 compared to the year ended December 31, 2014 primarily due to lower stock-based compensation expense and reduced overhead costs, mostly related to the reduced size of our operations following the Spin-Off in 2014. For the year ended December 31, 2014, stock-based compensation expense and employee-related costs were higher primarily due to the probable achievement of performance conditions under a special long-term retention and incentive equity and cash bonus awarded to certain employees in the year ended December 31, 2011.

Other Income (Expense), net and Interest Income

        Other income (expense), net and interest income, as compared to the prior years, were as follows:

        Other income (expense), net increased in the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to realized gain of $2.3 million from the repurchases of our 2023 Notes during the year ended December 31, 2016.

        Interest income increased in the year ended December 31, 2016 as compared to the year ended December 31, 2015 primarily due to higher interest generated from our investments in marketable securities.

        Other income (expense), net increased in the year ended December 31, 2015 compared to the year ended December 31, 2014 primarily related to a realized gain of $1.2 million on the sale of all of the ordinary shares of Theravance Biopharma that we held as of December 31, 2014 in the first quarter of 2015.

        Interest income decreased in the year ended December 31, 2015 as compared to the year ended December 31, 2014 primarily due to the full year effect of lower average cash balances resulting from the cash contribution to Theravance Biopharma in June 2014 and capital return programs in 2015.

        Other income (expense), net in the year ended December 31, 2014 includes a charge of $3.8 million recognized for the unrealized loss as of December 31, 2014 on Theravance Biopharma, Inc. ordinary shares owned by us.

Interest Expense

        Interest expense, as compared to the prior years, was as follows:

        Interest expense increased in the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to higher outstanding average principal balance on our 2029 Notes, of which $0.9 million was added in the first two quarters of 2016 and $43.2 million was added during the years ended December 31, 2015 and 2014 in the form of payment in kind ("PIK"). See "Liquidity" section below for further information.

        Interest expense increased in the year ended December 31, 2015 compared to the year ended December 31, 2014 primarily due to the issuance of our 2029 Notes in April 2014, and a subsequent increase of $43.2 million in the form of PIK to the outstanding principal balance, of which $22.7 million and $20.5 million was added during the years ended December 31, 2015 and 2014, respectively. See "Liquidity" section below for further information.

Income Taxes

        As of December 31, 2016 and 2015, we had net operating loss carryforwards for federal income taxes of $1.1 billion and $1.2 billion, respectively. As of December 31, 2016 and 2015, we had federal research and development tax credit carryforwards of $45.2 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.

39

---

Table of Contents

        We had unrecognized tax benefits of $15.5 million as of December 31, 2016 and 2015. None of our currently unrecognized tax benefits would affect our effective income tax rate if recognized, due to the valuation allowance that currently offsets our deferred tax assets.

        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 2015 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.

Discontinued Operations

        On June 1, 2014, we separated our research and drug development businesses from our late-stage partnered respiratory assets. The significant components of the research and drug development operations, which are presented as discontinued operations on the consolidated statements of operations, were as follows:

        There was no impact of the discontinued operations after the Spin-Off to our revenues and expenses for the year ended December 31, 2016 and 2015.

        Net revenues for the year ended December 31, 2014 includes revenue from collaborative arrangements, and products sales for which revenue recognition commenced in the first quarter of 2014, both of which were transferred to Theravance Biopharma as a part of the Spin-Off.

        Loss from discontinued operations for the year ended December 31, 2014 primarily relates to R&D expenses incurred prior to June 1, 2014 in addition to external legal and accounting fees in connection with our separation strategy and the additional stock-based compensation and cash bonus expense recognized due to the achievement of performance conditions under a special long-term retention and incentive equity and cash bonus awarded to certain employees in the year ended December 31, 2011, both of which we started to incur in the year ended December 31, 2013.

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 collaborative arrangements. Since the start of the commercialization of RELVAR^®/ BREO^® ELLIPTA^® in the fourth quarter of 2013 and ANORO^® ELLIPTA^® during 2014, we have complemented the source of financing with royalty revenues from the global net sales of these products by GSK. In the year ended December 31, 2016, we generated gross royalty revenues from GSK of $146.5 million. Net cash and cash equivalents, short-term investments and marketable securities totaled $150.4 million, and royalties receivable from GSK totaled $46.8 million as of December 31, 2016.

        In February 2017, we announced a new capital return plan, the 2017 Capital Return Plan. The 2017 Capital Return Plan authorizes a combination of repurchases of stock and/or repurchases, redemptions or prepayments of debt up to $150 million, through tender offers, open market purchases, private transactions, exchange offers or other means through December 31, 2017. The 2017 Capital Return Plan is expected to be funded using our working capital. We are not obligated to repurchase any specific dollar amount of debt or equity or number of shares of common stock under the 2017 Capital Return Plan. We will determine when, if and how to proceed with any repurchase transactions under the program, as well as the amount of any such repurchase transactions,

40

Table of Contents

based upon, among other things, our evaluation of our liquidity and capital needs (including for strategic and other opportunities), our business, results of operations, and financial position and prospects, general financial, economic and market conditions, prevailing market prices for shares of our common stock, corporate, regulatory and legal requirements, and other conditions and factors deemed relevant by our management and Board of Directors from time to time. Our 2017 Capital Return Plan may be suspended or discontinued at any time.

        In April 2014, we entered into certain note purchase agreements relating to the private placement of $450.0 million aggregate principal amount of our 2029 Notes. The 2029 Notes are secured exclusively by a security interest in a segregated bank account established to receive 40% of the royalties from global net sales and ending upon the earlier of full repayment of principal or May 15, 2029 due to us under the LABA Collaboration Agreement with GSK. As of December 31, 2016, the remaining balance of the 2029 Notes was $487.2 million.

Adequacy of Cash Resources to Meet Future Needs

        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 and financials forecasts. If our current operating plans and financial forecasts 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 currently planned. 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 Flows

        Cash flows, as compared to the prior years, were as follows:

Cash Flows from Operating Activities

        Net cash provided by operating activities for the year ended December 31, 2016 of $61.0 million was primarily due to:

•

$125.9 million provided by gross receipt of royalties from a related party (GSK) after adjusting for a $20.6 million increase in receivables from collaborative arrangements;



•

$15.9 million used for operating expenses, after adjusting for $8.4 million of non-cash related items, consisting primarily of stock-based compensation expense; and



•

$48.8 million used for interest payments on the 2023 Notes and 2029 Notes.

        Net cash provided by operating activities for the year ended December 31, 2015 of $10.1 million was primarily due to:

•

$51.2 million provided by gross receipt of royalties from a related party after adjusting for a $15.7 million increase in receivables from collaborative arrangements;



•

$15.4 million used for operating expenses, after adjusting for $7.0 million of non-cash related items, consisting primarily of stock-based compensation expense; and

Table of Contents

•

$25.9 million used for interest payments on the 2023 Notes and 2029 Notes.

        Net cash used in operating activities for the year ended December 31, 2014 of $130.7 million was primarily due to:

•

$100.5 million used for operating expenses;



•

$15.9 million decrease in payable to Theravance Biopharma;



•

$4.8 million increase in interest payments on convertible subordinated notes payable;



•

$1.9 million used to increase inventories, all incurred prior to the Spin-Off;



•

$7.7 million decrease in accounts payable primarily due to the timing of payments and our ongoing operations being significantly smaller due to the Spin-Off; and



•

$3.2 million from the decrease in deferred revenue.

Cash Flows from Investing Activities

        Net cash used in investing activities for the year ended December 31, 2016 of $4.6 million was primarily due to $95.7 million in purchases of marketable securities, partially offset by $91.4 million of proceeds received from the sale and maturities of marketable securities.

        Net cash provided by investing activities for the year ended December 31, 2015 of $159.2 million was primarily due to $245.7 million of proceeds received from the sale and maturities of marketable securities, partially offset by $86.5 million in purchases of marketable securities.

        Net cash used in investing activities in the year ended December 31, 2014 of $65.1 million was primarily due to $135.0 million used for payments to GSK for registrational and launch-related milestone fees, partially offset by $69.7 million from the sale and maturities of marketable securities, net of purchases.

Cash Flows from Financing Activities

        Net cash used in financing activities for the year ended December 31, 2016 of $97.6 million was primarily due to $78.1 million paid for the repurchases of common stock, $11.6 million repurchases of our 2023 Notes, and payments on principal of our 2029 Notes of $6.8 million.

        Net cash used in financing activities for the year ended December 31, 2015 of $106.9 million was primarily due to $87.3 million of cash dividends paid to our stockholders and $25.6 million paid for the repurchases of common stock, partially offset by $6.0 million of proceeds received from the issuance of our common stock.

        Net cash provided by financing activities in the year ended December 31, 2014 of $149.1 million was primarily due to net proceeds of $434.7 million received from the private placement of our 2029 Notes and $48.9 million received from the issuance of our common stock. These increases were partially offset by $277.5 million of cash and cash equivalents contributed to Theravance Biopharma in connection with the Spin-Off and payments of cash dividends of $57.0 million to our stockholders.

Off-Balance Sheet Arrangements

        Upon the Spin-Off, our facility leases in South San Francisco, California were assigned to Theravance Biopharma. However, if Theravance Biopharma were to default on its lease obligations, we would be held liable by the landlord and thus, we have in substance guaranteed the lease payments for these facilities. We would also be responsible for lease-related payments including utilities, property taxes, and common area maintenance, which may be as much as the actual lease payments. As of December 31, 2016, the total remaining lease payments for the duration of the lease, which runs through May 2020, were $21.7 million. The carrying value of this lease guarantee was $1.1 million as of December 31, 2016 and is reflected in other long-term liabilities in our consolidated balance sheet.

Table of Contents

Commitments and Contingencies

        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, 2016.

Contractual Obligations and Commercial Commitments

        In April 2014, we entered into certain note purchase agreements relating to the private placement of $450.0 million aggregate principal amount of the 2029 Notes. Since issuance, $44.0 million of interest expense has been added to the principal balance of the 2029 Notes, of which $0.9 million, $22.7 million and $20.5 million was added during the years ended December 31, 2016, 2015, and 2014, respectively. During the year ended December 31, 2016, the principal balance of the 2029 Notes was paid down by $6.8 million with the payments received from the royalty revenues generated in the previous quarters ended June 30 and September 30, 2016.

        In the table below, we set forth our significant enforceable and legally binding obligations and future commitments as of December 31, 2016.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

        We are exposed to interest rate risk related to our portfolio of investments in debt securities and the debt that we have issued. We account for our investments in debt securities at fair value, with unrealized gains or losses recorded as a component of other comprehensive income. We believe that our exposure to interest rate risk on our investment portfolio is immaterial as of December 31, 2016 and 2015, as the average remaining maturity of our investment portfolio was one month as of both dates.

        We account for our debt on an amortized cost basis and our recognized value of the debt does not reflect changes in fair value. Also, because our debt is fixed rate, our cash flows are not subject to variability as a result of changes in interest rates. However, we do disclose the estimated fair value of our debt and we are exposed to economic unrealized gains or losses that may occur as a result of interest rate fluctuations. As of December 31, 2016, the fair value of our 2023 Notes was estimated to be $202.1 million, based on available pricing information. The 2023 Notes bear interest at a fixed rate of 2.125%. As of December 31, 2016, the fair value of the 2029 Notes was estimated to be $487.2 million, based on available pricing information. The 2029 Notes bear interest at a fixed rate of 9% per annum. Information about the contractual maturities of our debt is disclosed in the table within the Contractual Obligations and Commercial Commitments section of Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

1.     DESCRIPTION OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Operations

Innoviva, Inc. (referred to as "Innoviva", the "Company", or "we" and other similar pronouns) is focused on bringing compelling new medicines to patients in areas of unmet need by leveraging its significant expertise in the development, commercialization and financial management of bio-pharmaceuticals. Innoviva's portfolio is anchored by the respiratory assets partnered with Glaxo Group Limited ("GSK"), including RELVAR^®/BREO^® ELLIPTA^® (fluticasone furoate/ vilanterol, "FF/VI") and ANORO^® ELLIPTA^® (umeclidinium bromide/ vilanterol, "UMEC/VI"). Under the Long-Acting Beta2 Agonist ("LABA") Collaboration Agreement and the Strategic Alliance Agreement with GSK (referred to herein as the "GSK Agreements"), Innoviva is eligible to receive the associated royalty revenues from RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^®. Innoviva is also entitled to 15% of any future payments made by GSK under its agreements originally entered into with us, and since assigned to Theravance Respiratory Company, LLC ("TRC"), relating to the combination FF/UMEC/VI and the Bifunctional Muscarinic Antagonist — Beta2 Agonist ("MABA") program, as monotherapy and in combination with other therapeutically active components, such as an inhaled corticosteroid, and any other product or combination of products that may be discovered and developed in the future under the LABA Collaboration Agreement ("LABA Collaboration"), which has been assigned to TRC other than RELVAR^®/BREO^®ELLIPTA^® and ANORO^® ELLIPTA^®.

Business Separation

On June 1, 2014, we separated our biopharmaceutical research and drug development operations from our late-stage partnered respiratory assets by transferring our research and drug development operations into our then wholly-owned subsidiary, Theravance Biopharma, Inc. ("Theravance Biopharma") (the "Spin-Off"). The Spin-Off resulted in Theravance Biopharma operating as an independent, publicly traded company.

The results of operations for the former research and drug development operations conducted by us and by Theravance Biopharma until June 1, 2014 are included as part of this report as discontinued operations. Refer to Notes 11 and 12, "Spin-Off of Theravance Biopharma, Inc.," and "Discontinued Operations" for further information.

Principles of Consolidation

The consolidated financial statements include the accounts of Innoviva 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 U.S. Generally Accepted Accounting Principles ("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. Management evaluates its significant accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and other relevant assumptions that we believe to be reasonable under the circumstances. These estimates also form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1.     DESCRIPTION OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Certain Risks and Concentrations

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and marketable securities. Although we deposit our cash with multiple financial institutions, our deposits, at times, may exceed federally insured limits. Refer to "Segment Reporting" below for concentrations with respect to revenues and geographic locations.

Segment Reporting

We operate in a single segment, which is to provide capital return to stockholders by maximizing the potential value of our respiratory assets partnered with GSK. Revenues are generated from our collaborative arrangements and royalty payments from GSK, located in Great Britain. Our facilities are located within the United States.

Variable Interest Entities

We evaluate our ownership, contractual and other interest in entities to determine if they are variable-interest entities ("VIE"), whether we have a variable interest in those entities and the nature and extent of those interests. Based on our evaluations, if we determine we are the primary beneficiary of such VIEs, we consolidate such entities into our financial statements. We consolidate the financial results of TRC, which we have determined to be a VIE, because we have the power to direct the economically significant activities of TRC and the obligation to absorb losses of, or the right to receive benefits from, TRC. The financial position and results of operations of TRC are not material for the periods presented.

Cash and Cash Equivalents

We consider 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.

Investments in Marketable Securities

We invest in short-term investments and marketable securities, primarily corporate notes, government, government agency, and municipal bonds. We limit 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. We classify our marketable securities as available-for-sale securities and report them at fair value in cash equivalents, short-term investments or marketable securities on the consolidated balance sheets with related unrealized gains and losses included as a component of stockholders' equity (deficit). The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, which is included in interest income on the consolidated statements of operations. Realized gains and losses, if any, on available-for-sale securities are included in interest income. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income.

We regularly review all of our investments for other-than-temporary declines in estimated fair value. Our 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 we have the intent to sell the securities and whether it is more likely than not that we will be required to sell the securities before the recovery of their amortized cost basis. When we determine that the decline in estimated fair value of an investment is below the amortized cost basis and the

1.     DESCRIPTION OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

decline is other-than-temporary, we reduce the carrying value of the security and record a loss for the amount of such decline to other income (expense), net.

Fair Value of Financial Instruments

We define 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.

Our valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. We classify these inputs into the following hierarchy:

Level 1 — Quoted prices for identical instruments in active markets.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 — Unobservable inputs and little, if any, market activity for the assets.

Financial instruments include cash equivalents, marketable securities, accounts receivable, receivables from collaborative arrangements, accounts payable, and accrued liabilities. Cash equivalents and marketable securities are carried at estimated fair value. The carrying value of accounts receivable, receivables from collaborative arrangements, accounts payable, and accrued liabilities approximate their estimated fair value due to the relatively short-term nature of these instruments.

Property and Equipment

Property and equipment as of December 31, 2016 and 2015, which consisted of computer equipment, software. office furniture and fixture, amounted to $0.4 million and $0.2 million, respectively.

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

Depreciation expense for the years ended December 31, 2016, 2015 and 2014 was $0.1 million, $0.1 million and $1.1 million. Depreciation expense for property and equipment used by our former research and drug development operations is classified within discontinued operations in the consolidated statements of operations for the year ended December 31, 2014. The change in accumulated depreciation is net of asset retirements.

Capitalized Software

We capitalize certain costs related to direct material and service costs for software obtained for internal use. Capitalized software costs are depreciated over three years.

Capitalized Fees Paid to a Related Party

We capitalize fees paid to licensors related to agreements for approved products or commercialized products. We capitalize these fees as capitalized fees paid to a related party ("Capitalized Fees") and amortize these Capitalized Fees on a straight-line basis over their estimated useful lives upon the commercial launch of the product, which has been shortly after regulatory approval of such product. The estimated useful lives of these Capitalized Fees are based on a country-by-country and product-by-product basis, as the later of the expiration or termination of the last patent right covering the compound in such product in such country and 15 years from first commercial sale of such product in such country, unless the agreement is terminated earlier. Consistent with our policy for classification of costs under the research and development collaborative arrangements, the amortization of these Capitalized Fees are recognized as a reduction of royalty revenue. We review our Capitalized Fees for impairment on a product-by-product basis for each major geographic area when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The recoverability of Capitalized Fees is measured by comparing the asset's carrying amount to the expected undiscounted future cash flows that the asset is expected to generate. The determination of recoverability typically requires various estimates and assumptions, including estimating the useful life over which cash flows will occur, their amount, and the asset's residual value, if any. We derive the required cash flow estimates from near-term forecasted product sales and long-term projected sales in the corresponding market.

Revenue Recognition

Revenue is recognized when the four basic criteria of revenue recognition are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. Where the revenue recognition criteria are not met, we defer the recognition of revenue by recording deferred revenue until such time that all criteria are met.

Collaborative Arrangements and Multiple-Element Arrangements

Revenue from nonrefundable, up-front license or technology access payments under license and collaborative arrangements that are not dependent on any future performance by us is recognized when such amounts are earned. If we have continuing obligations to perform under the arrangement, such fees are recognized over the estimated period of continuing performance obligation. For our arrangements with GSK, we recognize revenue from non-refundable, upfront fees and development contingent payments in the same manner as the final deliverable, which is ratably over the expected term of our performance of research and development services under the agreements. These upfront or contingent payments received, pending recognition as revenue, are recorded as deferred revenue. We periodically review the estimated performance period of our contracts based on the progress of our programs. The effect of any change made to an estimated performance period and, therefore revenue recognized, would occur on a prospective basis in the period that the change was made.

We account for contingent payments in accordance with Financial Accounting Standards Board (the "FASB") Subtopic Accounting Standards Codification ("ASC") 605-28 "Revenue Recognition — Milestone Method." 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. 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

53

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.

Royalties

We recognize royalty revenue on licensee net sales of products with respect to which we have contractual royalty rights in the period in which the royalties are earned and reported to us and collectability is reasonably assured. Royalties are recognized net of amortization of capitalized fees associated with any approval and launch milestone payments made to GSK.

Product Revenues

We currently have no product revenues following the Spin-Off.

Prior to the Spin-Off, we recognized revenues from product sales when there was persuasive evidence that an arrangement existed, title and risk of loss transferred, the price was fixed and determinable, and collectability was reasonably assured. Product sales were recognized net of estimated allowances, discounts, sales returns, chargebacks and rebates. Such amounts are presented within discontinued operations in the consolidated statements of operations.

Allowance for Doubtful Accounts

We maintain a policy to record allowances for potentially doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. As of December 31, 2016, there were no allowances for doubtful accounts and we have not had any write-offs historically.

Fair Value of Stock-Based Compensation Awards

We use the Black-Scholes-Merton 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 ("ESPP"). The Black-Scholes-Merton 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, "Share-Based Payment," for the expected option term. We use our historical volatility to estimate expected stock price volatility.

Restricted Stock Units ("RSUs") and Restricted Stock Awards ("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 was reduced for estimated forfeitures at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differed from those estimates. Our estimated annual forfeiture rates for stock options, RSUs and RSAs are based on our historical forfeiture experience.

The estimated fair value of stock options, RSUs and RSAs is expensed on a ratable or straight-line basis over the expected term of the grant or expected term of the vesting and the estimated fair value of performance-contingent RSUs and RSAs is expensed using an accelerated method over the term of the award once we have determined that it is probable that performance milestones will be achieved. Compensation expense for RSUs and RSAs that contain performance conditions is based on the grant date fair value of the award. Compensation expense is recorded over the requisite service period based on management's best estimate as to whether it is probable that the shares awarded are expected to vest. We

54

assess the probability of the performance milestones being met on a continuous basis. The grant date fair value of the RSUs and RSAs with a market condition is determined using a Monte Carlo valuation model and the compensation expense is recognized over the implied service period.

Compensation expense for purchases under the ESPP is recognized based on the fair value of the common stock on the date of offering, less the purchase discount percentage provided for in the plan.

Amortization of Debt Issuance Costs from Non-recourse Notes Payable, due 2029

In April 2014, we entered into certain note purchase agreements relating to the private placement of $450.0 million aggregate principal amount of non-recourse 9% fixed rate term notes due 2029 (the "2029 Notes") issued by our wholly-owned subsidiary.

We incurred approximately $15.3 million in transaction costs in connection with issuance of 2029 Notes, which we amortize to interest expense over the estimated life of the 2029 Notes based on the effective interest method. Since the principal and interest payments on the 2029 Notes are based on royalties from product sales, which will vary from quarter to quarter, the 2029 Notes may be repaid prior to the final maturity date in 2029. We continue to assess, on an ongoing basis, our estimates on royalties from products sales as it relates to its impact on payments of principal and interest on the 2029 Notes. To the extent that the interest or principal payments are greater or less than our initial estimates or the timing of such payments is materially different than our original estimates, we prospectively adjust the amortization of the debt issuance costs.

Income Taxes

We utilize 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.

None of our currently unrecognized tax benefits would affect our effective income tax rate if recognized, due to the valuation allowance that currently offsets our deferred tax assets. We do not anticipate the total amount of unrecognized income tax benefits relating to uncertain tax positions existing as of December 31, 2016 will significantly increase or decrease in the next 12 months.

We assess all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by relevant taxing authorities. Assessing an uncertain tax position begins with the initial determination of the position's sustainability and is measured at the largest amount of benefit that is greater than 50% likely to be realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain tax positions must be reassessed, and we will determine whether: the factors underlying the sustainability assertion have changed and whether the amount of the recognized tax benefit is still appropriate.

The recognition and measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit might change as new information becomes available.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of changes in unrealized and realized gains and losses on our marketable securities.

Related Parties

GSK owned 29.5% of our outstanding common stock as of December 31, 2016. Transactions with GSK are described in Note 3, "Collaborative Arrangements".

In filings with the Securities and Exchange Commission, BlackRock, Inc., a global provider of investment, advisory and risk management solutions, reported beneficial ownership of more than 5% of our outstanding common stock as of December 31, 2016 and 2015, respectively. We use an external asset manager, not affiliated with BlackRock, Inc., to manage a portion of our cash and investments portfolio. We had $64.3 million and $148.7 million invested in BlackRock Liquidity Money Market Fund as of December 31, 2016 and 2015, respectively, through our external asset manager. The money market fund invests in U.S. Treasury bills, notes, trust receipts and direct obligations of the U.S. Treasury and repurchase agreements relating to direct treasury obligations.

Prior to the Spin-Off, Robert V. Gunderson, Jr. was one of our directors. We have engaged Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, of which Mr. Gunderson is a partner, as our primary legal counsel. Fees incurred in the ordinary course of business were, $1.3 million in the year ended December 31, 2014. As Mr. Gunderson was not one of our directors for the years ended December 31, 2016 and 2015, he is no longer considered a related party.

Recently Issued Accounting Pronouncements Not Yet Adopted

In April 2016, the FASB issued ASU 2016-10 to clarify the implementation guidance on licensing and the identification of performance obligations consideration included in ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which is also known as ASC 606, was issued in May 2014 and outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. In March 2016, the FASB issued ASU 2016-08 to provide amendments to clarify the implementation guidance on principal versus agent considerations. ASU 2014-09 guidance is effective for the fiscal years and interim reporting periods beginning after December 15, 2017 (as amended through ASU 2015-14 issued in August 2015), with early adoption permitted. Companies can elect a full retrospective method to recast prior-period financial statements or a modified retrospective method to recognize the cumulative effect as an adjustment to the retained earnings in the initial year. We plan to implement the standard in the first quarter of 2018 on a modified retrospective basis and do not anticipate that this standard will have a material impact on our accounting for royalty revenues. We are continuing to assess the potential impacts of the standard on the accounting for other revenues associated with the collaboration agreements.

In February 2016, the FASB issued ASU 2016-02, Leases, which supersedes the lease recognition requirements in ASC Topic 840, Leases. The standard requires an entity to recognize right-of-use assets and lease liabilities arising from a lease for both financing and operating leases in the consolidated balance sheets but recognize the impact on the consolidated statement of operations and cash flows in a similar manner under current GAAP. The standard also requires additional qualitative and quantitative disclosures. The standard is effective for us at the beginning January 1, 2019 and requires transition under a modified retrospective method. The most significant impact of the update to us is that we will be required to

56

recognize a "right-of-use" asset and lease liability for the operating lease agreement that was not previously included on the balance sheet under the existing lease guidance. We anticipate that the treatment of the lease on our consolidated statement of operations and cash flows will be the same.

Recently Adopted Accounting Pronouncement

In April 2015, the FASB issued ASU 2015-03, Interest — Imputation of Interest ("ASU 2015-03"), to simplify the presentation of debt issuance costs. This standard amended existing guidance to require the presentation of debt issuance costs associated with term loans in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. We adopted ASU 2015-03 on January 1, 2016. Upon adoption of ASU 2015-03, we applied the guidance retrospectively to all periods presented and classified our debt issuance costs, which prior to adoption were included in other assets in the condensed consolidated financial statements, as a deduction to the respective long-term portion of our 2023 Notes and 2029 Notes.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), to simplify the accounting for the taxes related to stock based compensation, requiring excess tax benefits and deficiencies to be recognized as a component of income tax expense rather than equity. This guidance also requires excess tax benefits and deficiencies to be presented as an operating activity on the statement of cash flows and allows an entity to make an accounting policy election to either estimate expected forfeitures or to account for them as they occur. We adopted ASU 2016-09 in the first quarter of 2016, which resulted in an increase in our deferred tax assets related to the tax effect on stock-based compensation in our net operating losses. The adoption did not have a material effect on our financial statements because our deferred tax assets are subject to a full valuation allowance. We elected to account for forfeitures as they occur, rather than estimate expected forfeitures.

2.     NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common shares and dilutive potential common share equivalents then outstanding. Dilutive potential common share equivalents include the assumed exercise, vesting and issuance of employee stock awards using the treasury stock method, as well as common shares issuable upon assumed conversion of our convertible debt using the if-converted method.

3.     COLLABORATIVE ARRANGEMENTS

Net Revenue from Collaborative Arrangements

Net revenue from collaborative arrangements from continuing operations relates to our collaborative arrangement with GSK. Net revenue from other collaborative arrangements is reflected as discontinued operations in the consolidated statements of operations. Refer to Notes 1, 11 and 12, "Description of Operations and Summary of Significant Accounting Policies," "Spin-Off of Theravance Biopharma, Inc." and "Discontinued Operations" for further information.

Net revenue recognized under our GSK Agreements was as follows:

LABA Collaboration

In November 2002, we entered into our LABA Collaboration Agreement with GSK to develop and commercialize once-daily LABA products for the treatment of chronic obstructive pulmonary disease ("COPD") and asthma.

As a result of the launch and approval of RELVAR^®/BREO^® ELLIPTA^® and ANORO^® ELLIPTA^® in the U.S., Japan and Europe, we paid milestone fees to GSK totaling $220.0 million during the year ended December 31, 2014. Although we have no further milestone payment obligations to GSK pursuant to the LABA Collaboration Agreement, we continue to have ongoing participation as part of the collaboration, including joint steering and joint project committees that are expected to continue over the life of the agreements. The milestone fees paid to GSK were recognized as capitalized fees paid to a related party, which are being amortized over their estimated useful lives commencing upon the commercial launch of the product. The amortization expense is recorded as a reduction to the royalties from GSK.

We are entitled to receive annual royalties from GSK on sales of RELVAR^®/BREO^® ELLIPTA^® as follows: 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 ANORO^® ELLIPTA^®, royalties are upward tiering and range from 6.5% to 10%.

2004 Strategic Alliance

In March 2004, we entered into the Strategic Alliance Agreement with GSK where 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. 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 Innoviva-discovered preclinical MABA compounds (the "Additional MABAs"). The development program is fully funded by GSK and is still currently in early stages of Phase II trials. As a result of the transactions effected by the Spin-Off, we are only entitled to receive 15% of any

3.     COLLABORATIVE ARRANGEMENTS (Continued)

contingent payments and royalties payable by GSK from sales of FF/UMEC/VI (and MABA, and MABA/FF) while Theravance Biopharma receives 85% of those same payments.

GSK Contingent Payments and Revenue

The potential future contingent payments receivable related to the MABA program of up to $363.0 million are not deemed substantive milestones 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 Company is entitled to 15% of any milestone payments.

4.     AVAILABLE-FOR-SALE SECURITIES AND FAIR VALUE MEASUREMENTS

Available-for Sale Securities

The classification of available-for-sale securities in the consolidated balance sheets is as follows:

The estimated fair value of available-for-sale securities is based on quoted market prices for these or similar investments that were based on prices obtained from a commercial pricing service. Available-for-sale securities are summarized below:

 

As of December 31, 2016, all of the available-for-sale debt securities had contractual maturities within one year and the average duration of debt securities was approximately one month.

4.     AVAILABLE-FOR-SALE SECURITIES AND FAIR VALUE MEASUREMENTS (Continued)

During the year ended December 31, 2015, we recognized a gain of $1.2 million from the sale of all of the ordinary shares of Theravance Biopharma that we held as of December 31, 2014, which is included in other income (expense), net in the condensed consolidated statement of operations. In addition, we sold other available-for-sale securities totaling $100.4 million, and the related realized gains and losses were not significant during year ended December 31, 2015.

We recognized an unrealized loss of $3.8 million on our Theravance Biopharma equity securities as of December 31, 2014, which was determined to be other-than-temporary and charged to other income (expense), net on the consolidated statements of operations.

Fair Value Measurements

Our available-for-sale securities are measured at fair value on a recurring basis and our debt is carried at the amortized cost basis. The estimated fair values were as follows:

The fair value of our marketable securities classified within Level 2 is based upon observable inputs that may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications.

The fair value of our 2023 Notes and 2029 Notes is based on recent trading prices of the instruments.

5.     CAPITALIZED FEES PAID TO A RELATED PARTY

We capitalize fees paid to licensors related to agreements for approved products or commercialized products. We capitalize these fees as capitalized fees paid to a related party ("Capitalized Fees") and amortize these Capitalized Fees on a straight-line basis over their estimated useful lives upon the commercial launch of the product, which is expected to be shortly after regulatory approval of such product. The estimated useful lives of these Capitalized Fees are based on a country-by-country and product-by-product basis, as the later of the expiration or termination of the last patent right covering the compound in such product in such country and 15 years from first commercial sale of such product in such country, unless the agreement is terminated earlier. Capitalized fees paid to a related party, which consist of registrational and launch-related milestone fees paid to GSK, were as follows:

These milestone fees are being amortized over their estimated useful lives commencing upon the commercial launch of the product in their respective regions with the amortization expense recorded as a reduction in revenue from collaborative arrangements. As of December 31, 2016, the weighted average remaining amortization period is 13.1 years.

Additional information regarding these milestone fees is included in Note 3, "Collaborative Arrangements." Amortization expense for the years ended December 31, 2016, 2015 and 2014 were $13.8 million, $13.8 million and $11.1 million. The remaining estimated amortization expense is $13.8 million for each of the years from 2017 to 2021 and $111.4 million thereafter.

6.     STOCK-BASED COMPENSATION

Equity Incentive Plans

In May 2012, we adopted the 2012 Equity Incentive Plan (the "2012 Plan"). The 2012 Plan provides for the grant of incentive stock options, nonstatutory stock options, restricted stock awards, stock unit awards and SARs to employees, non-employee directors and consultants. As of December 31, 2016, total shares remaining available for issuance under the 2012 Plan were 3,573,436.

Employee Stock Purchase Plan

Under the 2004 Employee Stock Purchase Plan (the "ESPP"), our employees may purchase common stock through payroll deductions at a price equal to 85% 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

62

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6.     STOCK-BASED COMPENSATION (Continued)

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 15 or November 15. ESPP contributions are limited to a maximum of 15% of an employee's eligible compensation. The maximum number of shares that an employee may purchase in any purchase period is 2,500. An employee may not purchase shares with a value greater than $25,000 in any calendar year.

As of December 31, 2016, total shares remaining available for issuance under the ESPP were 237,627.

Performance-Contingent RSAs and RSUs

Since 2011, the Compensation Committee of our Board of Directors (the "Compensation Committee") has approved grants of performance-contingent RSAs to senior management and a non-executive officer. Generally, these awards have dual triggers of vesting based upon the achievement of certain performance goals by a pre-specified date, as well as a requirement for continued employment. Recognition of stock-based compensation expense begins when the performance goals are deemed probable of achievement.

Included in these performance-contingent RSAs is the grant of 1,290,000 special long-term retention and incentive performance-contingent RSAs to senior management in 2011. The awards have dual triggers of vesting based upon the achievement of certain performance conditions over a six-year timeframe from 2011 through December 31, 2016 and require continued employment. As of March 31, 2014, we determined that the achievement of the requisite performance conditions for vesting of the first tranche of these awards was probable and the total stock-based compensation expense of $7.0 million for the first tranche was fully recognized through May 2014. In connection with the Spin-Off, our Compensation Committee approved the modification of the remaining tranches related to these awards as the performance conditions associated with the remaining portions of these awards were unlikely to be consistent with the new strategies of each company following the Spin-Off. The remaining 63,000 RSAs for which service-based vesting was not triggered at the time of the Spin-Off remain subject to new performance conditions (as well as the original service conditions). In addition, the RSAs for which both the performance and service-based conditions were not achieved prior to the Spin-Off were entitled to the pro rata dividend distribution made by the Company on June 2, 2014 of one ordinary share of Theravance Biopharma for every 3.5 shares of the Company's common stock subject to their awards, which will also be subject to the same new performance and service conditions as the original RSAs to which they relate. During the year ended December 31, 2016, we determined that the achievement of the requisite performance conditions was met and, as a result, $1.3 million compensation cost was recognized for the remaining equity awards.

On January 14, 2016, the Compensation Committee approved and granted 282,394 RSAs and 46,294 RSUs to senior management. These awards include a market condition based on Relative Total Shareholder Return ("TSR") and a service condition that requires continued employment, collectively the "Performance Measures". The vesting percentages of these awards are calculated based on the two-year TSR with a catch-up provision opportunity measured on January 13, 2019 for RSAs and on September 30, 2018 for RSUs. Two-thirds of amounts earned at the end of year two will vest and be distributed on February 20, 2018, while the final one-third earned after two years as well as the catch-up amount earned will vest and be distributed on February 20, 2019 for RSAs and November 20, 2018 for RSUs. The actual payout of shares may range from a minimum of zero shares to a maximum of 328,688 shares granted upon the actual performance against the Performance Measures. The grant date fair value of these awards is determined using a Monte Carlo valuation model. The aggregate value of $2.0 million is recognized as compensation expense over the implied service period and will not be reversed if the market condition is not met.

Director Compensation Program

Our non-employee directors receive compensation for services provided as a director. Each member of our Board of Directors who is not an employee receives an annual cash retainer for services as a director, member of a committee of the Board of Directors, lead independent director and chairman, as applicable.

Each of our independent directors receives periodic automatic grants of equity awards under a program implemented under the 2012 Plan. These grants are non-discretionary. Only our independent directors or affiliates of such directors are eligible to receive automatic grants under the 2012 Plan. Under the program, as amended following the Spin-Off, each individual who first becomes a non-employee director will, on the date such individual joins the Board of Directors, automatically be granted a one-time grant of RSUs covering a number of shares of our common stock calculated as $250,000 divided by our common stock closing share price on the date of grant as reported on The NASDAQ Global Select Market, rounded down to the nearest whole share (the "Initial RSUs"), plus a one-time grant of RSUs covering a number of shares of our common stock calculated as $250,000 divided by our common stock closing share price on the date of grant as reported on The NASDAQ Global Select Market, which would be pro-rated for the number of whole months remaining until the anniversary of the prior year's stockholders' meeting, rounded down to the nearest whole share (the "Pro Rata RSUs"). The Initial RSUs vest in two equal annual installments, while Pro-Rata RSUs vest in a single installment at the sooner of the next annual stockholder meeting or the one-year grant anniversary, in each case subject to the non-employee director's continuous service through the applicable vesting date.

Annually, upon his or her re-election to the Board at the Annual Meeting of Stockholders, each non-employee director is automatically granted an RSU covering a number of shares of our common stock calculated as $250,000 divided by our common stock closing share price on the date of grant as reported on The NASDAQ Global Select Market, rounded down to the nearest whole share. Annual RSUs will vest at the sooner of the next annual stockholder meeting or the one-year anniversary of grant, subject to the non-employee director's continuous service through the applicable vesting date.

These RSUs will vest in full upon the director's death or the occurrence of a Change in Control before the director's service terminates. All director RSUs will be settled in shares of our common stock on the vesting date. Director RSUs will carry dividend equivalent rights to be credited with an amount equal to all cash dividends paid on the underlying shares of common stock while unvested. Dividend equivalents will be subject to the same terms and conditions, including vesting, as the RSUs to which they attach and will be paid in cash upon vesting.

Stock-Based Compensation Expense

In connection with the Spin-Off of Theravance Biopharma, all outstanding shares of Theravance Biopharma were distributed to our stockholders as a pro-rata dividend distribution on June 2, 2014 by issuing one ordinary share of Theravance Biopharma for every 3.5 shares held of Innoviva common stock to stockholders of record on May 15, 2014. Outstanding stock options and RSUs that were not eligible for the dividend distribution were adjusted for the Spin-Off of Theravance Biopharma. The number of shares and exercise price for all outstanding stock options were adjusted and the number of shares for all outstanding RSUs was adjusted. All other terms of these grants remain the same; provided, however, that the vesting and expiration of these grants are based on the holder's continuing employment or service with us or Theravance Biopharma, as applicable.

6.     STOCK-BASED COMPENSATION (Continued)

Although the anti-dilution adjustments were required pursuant to the terms of each stock plan, the anti-dilution adjustments were calculated using a volume-weighted average stock price, rather than the stock price as of the date of the dividend distribution, which resulted in incremental compensation expense. The accounting impact of the adjustment to the outstanding stock options and RSUs that occurred in connection with the Spin-Off of Theravance Biopharma was measured by comparing of the fair values of the modified stock options and RSUs to our employees and directors immediately before and after the adjustment. As a result, we recognized incremental stock-based compensation expense of $1.2 million in the second quarter of 2014, of which $0.9 million is included in discontinued operations. All remaining unrecognized stock-based compensation expense associated with this adjustment will be recognized by Theravance Biopharma as it pertains to stock options and RSUs held by individuals now employed by Theravance Biopharma or one if its affiliates.

Stock-based compensation expense is included in the consolidated statements of operations as follows:

Stock-based compensation expense included in the consolidated statements of operations by award type is as follows:

Our debt consists of:

Convertible Subordinated Notes Due 2023

In January 2013, we completed an underwritten public offering of $287.5 million aggregate principal amount of unsecured convertible subordinated notes, which will mature on January 15, 2023 (the "2023 Notes"). The financing raised proceeds, net of issuance costs, of approximately $281.2 million, less $36.8 million to purchase two privately-negotiated capped call option transactions in connection with the issuance of the notes. The 2023 Notes bear interest at the rate of 2.125% per year that is payable semi-annually in arrears in cash on January 15 and July 15 of each year, beginning on July 15, 2013.

7.     DEBT (Continued)

The 2023 Notes were convertible, at the option of the holder, into shares of our common stock at an initial conversion rate of 35.9903 shares per $1,000 principal amount of the 2023 Notes, subject to adjustment in certain circumstances, which represents an initial conversion price of approximately $27.79 per share.

In connection with the offering of the 2023 Notes, we entered into two privately-negotiated capped call option transactions with a single counterparty. The capped call option transaction is an integrated instrument consisting of a call option on our common stock purchased by us with a strike price equal to the initial conversion price of $27.79 per share for the underlying number of shares and a cap price of $38.00 per share, both of which are subject to adjustments consistent with the 2023 Notes. The cap component is economically equivalent to a call option sold by us for the underlying number of shares with an initial strike price of $38.00 per share. As an integrated instrument, the settlement of the capped call coincides with the due date of the convertible debt. Upon settlement, we would receive from our hedge counterparty a number of shares of our common shares that would range from zero, if the stock price was below $27.79 per share, to a maximum of 2,779,659 shares, if the stock price is above $38.00 per share. However, if the market price of our common stock, as measured under the terms of the capped call transactions, exceeds $38.00 per share, there is no incremental anti-dilutive benefit from the capped call.

Following the Spin-Off of Theravance Biopharma in June 2014, the partial conversion by certain holders of the 2023 Notes in July 2014, and dividends declared and paid in 2014 and 2015, the conversion rate with respect to our 2023 Notes was adjusted in total to 50.5818 shares of our common stock per $1,000 principal amount of the 2023 Notes, which represents a conversion price of approximately $19.77 per share. As a result of the conversion rate adjustments, the capped call strike price and cap price were also adjusted accordingly to $19.77 and $27.04.

For the year ending December 31, 2016, we retired a portion of our 2023 Notes with a face value of $14.1 million and carrying value of $13.9 million by way of purchase in the open market. The 2023 Notes were purchased for a total settlement price of $11.6 million resulting in a gain of $2.3 million, which is included in other income (expense), net in the condensed consolidated statement of operations. As a result of the partial retirement of our 2023 Notes, we entered into partial termination agreement of the capped call option transaction described above. The partial termination agreement of the capped call option transaction enabled us to receive $0.6 million from the counterparty, which was recorded as an increase in additional paid-in capital in our condensed consolidated balance sheets as of December 31, 2016.

Non-Recourse Notes Due 2029

In April 2014, we entered into certain note purchase agreements relating to the private placement of $450.0 million aggregate principal amount of non-recourse fixed rate term notes due 2029 (the "2029 Notes") issued by our wholly-owned subsidiary.

The 2029 Notes are secured by a security interest in a segregated bank account established to receive 40% of royalties due to us under the LABA Collaboration with GSK commencing on April 1, 2014 and ending upon the earlier of full repayment of principal or May 15, 2029. The amounts in the segregated bank account can only be used to make interest and principal payments on the 2029 Notes. As of December 31, 2016 and 2015, the balance of the segregated bank account was not material.

The 2029 Notes bear an annual interest rate of 9%, with interest and principal paid quarterly beginning November 15, 2014. The 2029 Notes may be redeemed at any time prior to maturity, in whole or in part, at specified redemption premiums. Prior to May 15, 2016, in the event that the specified portion of royalties received in a quarter is less than the interest accrued for the quarter, the principal amount of the 2029 Notes increased by the interest shortfall amount for that period, and considered as payment in kind ("PIK"). Since issuance, $44.0 million of interest expense has been added to the principal balance of the 2029 Note, of which $0.9 million and $22.7 million was added during the years ended December 31, 2016

and 2015, respectively. During the year ended December 31, 2016, the principal balance of the 2029 Notes was paid down by $6.8 million with the payments received from the royalty revenues generated in the previous quarters ended June 30 and September 30, 2016. Since the principal and interest payments on the 2029 Notes are based on royalties from product sales recorded by GSK, which will vary from quarter to quarter and are unknown to us, the 2029 Notes may be repaid prior to the final maturity date in 2029. The 2029 Notes can be prepaid subject to a prepayment premium of 5% until April 17, 2016, 2.5% thereafter until April 17, 2017, and without premium afterwards.

In connection with the sale of the 2029 Notes, we incurred approximately $15.3 million in debt issuance costs, which are being amortized to interest expense over the estimated life of the 2029 Notes.

As of December 31, 2016, the principal balance of the 2029 Notes was $487.2 million, which will be partially paid down by $7.8 million in the next quarterly payment expected to be made in February 2017. This payment is based on our royalty revenues of $46.8 million for the three months ended December 31, 2016.

Dividends

On February 20, 2015, our Board of Directors declared a quarterly dividend of $0.25 per share of common stock to stockholders of record as of the close of business on March 12, 2015. This dividend was paid on March 31, 2015. On April 24, 2015, our Board of Directors declared a quarterly dividend of $0.25 per share of common stock to stockholders of record as of the close of business on June 12, 2015. This dividend was paid on June 30, 2015. On July 24, 2015, our Board of Directors declared a quarterly dividend of $0.25 per share of common stock to stockholders of record as of the close of business on September 10, 2015. This dividend was paid to our stockholders on September 30, 2015. During the year ended December 31, 2015, we paid an aggregate of $87.3 million in dividends. Unvested RSAs and certain unvested RSUs as of the record date are also entitled to dividends, which will only be paid when the RSAs and such RSUs vest and are released. For further information on the impact of the cash dividend payments on the 2023 Notes, refer to Note 7, "Debt".

On October 16, 2014, our Board of Directors declared a quarterly dividend of $0.25 per share of common stock to stockholders of record as of the close of business on November 25, 2014. This dividend was paid on December 31, 2014.

This dividend was paid on September 18, 2014.

Share Repurchase Program

On October 28, 2015, we announced the 2016 Share Repurchase Program. As a component of the Share Repurchase Program, on October 30, 2015, we commenced a "modified Dutch auction" tender offer (the "October 2015 TO") to purchase up to $75 million of our common stock, at a price per share of not less than $8.50 and not greater than $9.25, which will be contingent upon satisfaction of customary conditions. The October 2015 TO expired on December 1, 2015. The following table shows our share repurchase activity and related information on the October 2015 TO:

9.     COMMITMENTS AND CONTINGENCIES

Operating Lease and Lease Guarantee

Upon the Spin-Off, our facility leases in South San Francisco, California were assigned to Theravance Biopharma. However, if Theravance Biopharma were to default on its lease obligations, we have in substance guaranteed the lease payments for these facilities. We would also be responsible for lease-related payments including utilities, property taxes, and common area maintenance, which may be as much as the actual lease payments. As of December 31, 2016, the total remaining lease payments, which run through May 2020, were $21.7 million. The carrying value of this lease guarantee was $1.1 million as of December 31, 2016 and is reflected in other long-term liabilities in our consolidated balance sheet. Amortization on the lease guarantee commenced in 2016 and amortization expense for the year ended December 31, 2016 was $0.2 million.

On June 10, 2016, we executed a lease for our new corporate headquarters in Brisbane, California. The term of the new lease is seven years, subject to our right to extend the lease. Minimum lease payments under the new lease are as follows as of December 31, 2016:

In connection with entering into the new lease, we terminated our sublease by and between us and Theravance Biopharma, dated June 2, 2014 (the "Gateway Sublease"). The Gateway Sublease was set to expire on May 31, 2020. On June 10, 2016, we executed a Sublease Termination Agreement with Theravance Biopharma to terminate the Gateway Sublease (the "Gateway Sublease Termination Agreement"). No termination fee was payable to Theravance Biopharma as a result of this Gateway Sublease Termination Agreement.

Guarantees and Indemnifications

We indemnify our officers and directors for certain events or occurrences, subject to certain limits. We believe the fair value of these indemnification agreements is minimal. Accordingly, we have not recognized any liabilities relating to these agreements as of December 31, 2016.

10.   INCOME TAXES

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 our deferred tax assets are as follows:

The differences between the U.S. federal statutory income tax rate to our effective tax rate are as follows:

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 $20.6 million in the year ended December 31, 2016, increased by $4.7 million in the year ended December 31, 2015, and decreased by $103.8 million in the year ended December 31, 2014.

The increase in the valuation allowance in the year ended December 31, 2016 was primarily due to early adoption of the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, ("ASU 2016-09"), for which we recognized additional excess stock option tax benefits of $46.9 million in net operating loss carryforwards.

The increase in the valuation allowance in the year ended December 31, 2015 was primarily a result of net operating loss carryforwards.

As of December 31, 2016, we had federal net operating loss carryforwards of approximately $1.1 billion, which will expire from 2025 through 2035, and federal research and development tax credit carryforwards of approximately $45.2 million, which will expire from 2018 through 2034. We also had state net operating loss carryforwards of approximately $674.3 million expiring in the years 2017 through 2035 and state research tax credits of approximately $32.3 million, which do not expire.

INNOVIVA, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

10.   INCOME TAXES (Continued)

The net operating loss deferred tax asset balances as of December 31, 2016 include excess tax benefits from stock option exercises due to early adoption of ASU 2016-09.

Utilization of net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations provided by the Internal Revenue Code and similar state provisions. Annual limitations may result in expiration of net operating loss and tax credit carryforwards before some or all of such amounts have been utilized.

Our policy is to recognize interest and/or penalties related to income tax matters in income tax expense. As of December 31, 2016 and 2015, we had no accrued interest or penalties.

We conducted an analysis through the year ended December 31, 2015 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 as a result of those identified ownership changes. If we undergo another ownership change, the utilization of the pre-ownership change net operating loss carryforwards or pre-ownership change tax attributes, such as research tax credits, to offset the post-ownership change income may be subject to an annual limitation, pursuant to Section 382 and 383 of the Internal Revenue Code of 1986, as amended. Similar rules may apply under state tax laws.

Uncertain Tax Positions

A reconciliation of the beginning and ending balances of the total amounts of unrecognized tax benefits are as follows (in thousands):

In the event that we are able to recognize these uncertain positions, most of the $15.5 million of the unrecognized benefit would reduce our effective tax rate. We currently have a full valuation allowance against our deferred tax assets, which would impact the timing of the effective tax rate benefit, should any of these uncertain positions be favorably settled in the future. We do not believe it is reasonably possible that our unrecognized tax benefits will significantly change within the next twelve months.

We are subject to taxation in the U.S. and various state jurisdictions. The tax years 1999 and forward remain open to examination by the federal and most state tax authorities due to net operating loss and overall credit carryforward positions.

11.   SPIN-OFF OF THERAVANCE BIOPHARMA, INC.

On June 1, 2014, we separated our late-stage partnered respiratory assets from our biopharmaceutical research and drug development operations. We contributed the assets and certain liabilities from the research and drug development operations and $393.0 million of cash, cash equivalents and marketable securities to Theravance Biopharma. All outstanding shares of Theravance Biopharma were then

distributed to our stockholders of record on May 15, 2014 as a pro-rata dividend distribution of one ordinary share of Theravance Biopharma for every 3.5 shares held of our common stock.

On June 1, 2014, we entered into a Separation and Distribution Agreement with Theravance Biopharma that set forth the terms and conditions of the separation of Theravance Biopharma from us. The Separation and Distribution Agreement sets forth a framework for the relationship between us and Theravance Biopharma following the separation regarding principal transactions necessary to separate Theravance Biopharma from us. This agreement also sets forth other provisions that govern certain aspects of our relationship with Theravance Biopharma after the completion of the separation from us and provides for the allocation of assets, liabilities and obligations between Theravance Biopharma and us in connection with the Spin-Off.

In addition, we entered into other definitive agreements in connection with the Spin-Off, including (1) a Transition Services Agreement pursuant to which Theravance Biopharma and we will provide each other with a variety of administrative services, including financial, tax, accounting, information technology, legal and human resources services, for a period of time of up to 12 months following the Spin-Off, (2) a Tax Matters Agreement that generally governs the parties' respective rights, responsibilities and obligations after the separation with respect to taxes, (3) the Gateway Sublease and (4) an Employee Matters Agreement that allocates liabilities and responsibilities relating to employee compensation, benefit plans, programs and other related matters in connection with the separation, including the treatment of outstanding incentive awards and certain retirement and welfare benefit obligations. These arrangements contain the provisions related to the Spin-Off and the distribution of Theravance Biopharma's ordinary shares to our stockholders.

Due to the Spin-Off, the leases for the facilities in South San Francisco, California, which formerly served as our headquarters, were assigned to Theravance Biopharma. We would be held liable by the landlord if Theravance Biopharma defaults under its lease obligations, and thus, we have in substance guaranteed the payments under the lease agreements for these facilities. See Note 9, "Commitments and Contingencies" for further information on this lease guarantee.

Theravance Biopharma's historical results of operations have been presented as discontinued operations in our consolidated statement of operations for the year ended December 31, 2014. See Note 12, "Discontinued Operations," for further information.

12.   DISCONTINUED OPERATIONS

On June 1, 2014, we separated our research and drug development businesses from our late-stage partnered respiratory assets.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Innoviva, Inc.

        We have audited the accompanying consolidated balance sheets of Innoviva, Inc. as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive income (loss), stockholders' equity (deficit) and cash flows for each of the three years in the period ended December 31, 2016. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Innoviva, Inc. as of December 31, 2016 and 2015, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2016, in conformity with U.S. generally accepted accounting principles.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Innoviva Inc.'s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 28, 2017 expressed an unqualified opinion thereon.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures.

        We conducted an evaluation as of December 31, 2016, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, which are defined under SEC rules as controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files under the Securities Exchange Act of 1934 (Exchange Act) is recorded, processed, summarized and reported within required time periods. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective.

Management's Report on Internal Control over Financial Reporting

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

        Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on criteria established in the Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Management's assessment included evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2016.

        Our independent registered public accounting firm, Ernst & Young LLP, has audited our internal control over financial reporting as of December 31, 2016. Their attestation report on the audit of our internal control over financial reporting is included below.

Limitations on the Effectiveness of Controls

        Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefit of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Innoviva have been detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting

        There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 of the Exchange Act, which occurred during the fourth fiscal quarter of the year ended December 31, 2016 which has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Innoviva, Inc.

        We have audited Innoviva, Inc.'s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Innoviva, Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, Innoviva, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Innoviva, Inc. as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive income (loss), stockholders' equity (deficit) and cash flows for each of the three years in the period ended December 31, 2016 of Innoviva, Inc. and our report dated February 28, 2017, expressed an unqualified opinion thereon.

Exhibit 10.72

PARTIAL TERMINATION AGREEMENT
dated as of December 13, 2016
Between INNOVIVA, INC. and BANK OF AMERICA, N.A.

        THIS PARTIAL TERMINATION AGREEMENT (this "Agreement") with respect to the Capped Call Confirmations (as defined below) is made as of December 13, 2016, between Innoviva, Inc. ("Company") and Bank of America, N.A. ("Dealer").

        WHEREAS, Company issued $287,500,000 principal amount of 2.125% Convertible Senior Notes due 2023 (the "Convertible Notes") pursuant to an Indenture dated as of January 24, 2013 between Company and The Bank of New York Mellon Trust Company, N.A., as trustee;

        WHEREAS, in connection with the issuance of the Convertible Notes, Company and Dealer entered into a Base Capped Call Transaction (Transaction Reference Number: 138120785) (the "Base Capped Call Transaction") pursuant to an ISDA confirmation dated as of January 17, 2013, which supplements, forms a part of, and is subject to an agreement in the form of the 2002 ISDA Master Agreement, pursuant to which Company purchased from Dealer 250,000 call options (as amended, modified, terminated or unwound from time to time, the "Base Capped Call Confirmation");

        WHEREAS, in connection with the exercise of the over-allotment option by the initial purchasers of the Convertible Notes, Company and Dealer entered into an Additional Capped Call Transaction (Transaction Reference Number: 138123249) (the "Additional Capped Call Transaction" and, together with the Base Capped Call Transaction, the "Capped Call Transactions") pursuant to an ISDA confirmation dated as of January 18, 2013, which supplements, forms a part of, and is subject to an agreement in the form of the 2002 ISDA Master Agreement, pursuant to which Company purchased from Dealer an additional 37,500 call options (as amended, modified, terminated or unwound from time to time, the "Additional Capped Call Confirmation" and, together with the Base Capped Call Confirmation, the "Capped Call Confirmations");

        WHEREAS, on July 31, 2014, the Base Capped Call Confirmation was amended to reflect a partial termination of 32,391 options, leaving 217,609 options outstanding under the Base Capped Call Transaction following such partial termination and except as expressly modified therein, the Capped Call Confirmations remained in full and effect;

        WHEREAS, on May 11, 2016, the Additional Capped Call Confirmation was amended to reflect a partial termination of 10,000 options, leaving 27,500 options outstanding under the Additional Capped Call Transaction following such partial termination and except as expressly modified therein, the Capped Call Confirmations remained in full and effect; and

        WHEREAS, in connection with a repurchase by Company of 4,125 Convertible Notes in $1,000 principal amount denominations (such number of Convertible Notes in $1,000 principal amount denominations, the "Repurchase Number"), Company has requested partial termination of the Additional Capped Call Transaction;

        NOW, THEREFORE, in consideration of their mutual covenants herein contained, the parties hereto, intending to be legally bound, hereby mutually covenant and agree as follows:

        1.    Defined Terms.    Any capitalized term not otherwise defined herein shall have the meaning set forth for such term in the Capped Call Confirmations.

        2.    Partial Termination.    Notwithstanding anything to the contrary in the Capped Call Confirmations, Company and Dealer agree that, effective on the date hereof and following the partial termination contemplated hereby, the Number of Options remaining outstanding under the Additional Capped Call Transaction shall be reduced to 23,375, and in connection therewith Dealer shall be required to pay to Company the Cash Settlement Amount on the Payment Date pursuant to Sections 3 and 4 below.

        3.    Payments and Deliveries.    On the third Scheduled Trading Day following the Averaging Date (as defined below) or, if such day is not a Clearance System Business Day, on the next Clearance System Business Day immediately following such day (the "Payment Date"), Dealer shall pay to Company in immediately available funds cash in an amount equal to the Cash Settlement Amount. The "Cash Settlement Amount" shall mean an amount in US Dollars determined by Dealer according to the table set forth in Schedule A attached hereto (using linear interpolation or commercially reasonable extrapolation by

---

Dealer, as applicable, to determine the Cash Settlement Amount for any VWAP Price not specifically appearing in Schedule A).

        4.    Valuation.    "Averaging Date" means December 14, 2016; provided, however, that if such date is a Disrupted Day in whole, such date shall not constitute the Averaging Date, and the Averaging Date shall occur on the Scheduled Trading Day after the date that would otherwise be the Averaging Date. "VWAP Price" means the per Share volume-weighted average price as displayed under the heading "Bloomberg VWAP" on Bloomberg page INVA <equity> AQR (or any successor thereto) in respect of the period from 9:30 am to 4:00 pm (New York City time) on the Averaging Date (or if such volume-weighted average price is unavailable, the market value of one Share on the Averaging Date for such time period, as determined by Dealer in a good faith, commercially reasonable manner). Notwithstanding the foregoing, if (i) the Averaging Date is a Disrupted Day in part or (ii) Dealer determines in its commercially reasonable judgment that an additional Averaging Date is reasonably necessary to preserve Dealer's hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect sales of Shares in connection with its hedge unwind activity hereunder in a manner that would be in compliance with applicable legal, regulatory or self-regulatory requirements, or with internal policies and procedures, then the VWAP Price for such additional Averaging Date shall be the volume-weighted average price per Share on such Scheduled Trading Day on the Exchange for such time period, as determined by Dealer in a commercially reasonable manner and the Cash Settlement Amount shall be adjusted by Dealer in its good faith, commercially reasonable discretion to account for such disruption and/or extension.

        5.    Representations and Warranties of Company.    Company represents and warrants to Dealer on the date hereof that:

        (a)   it has the power to execute this Agreement and any other documentation relating to this Agreement to which it is a party, to deliver this Agreement and to perform its obligations under this Agreement and has taken all necessary action to authorize such execution, delivery and performance;

        (b)   such execution, delivery and performance do not violate or conflict with any law applicable to it, any provision of its constitutional documents, any order or judgment of any court or other agency of government applicable to it or any of its assets or any material contractual restriction binding on or affecting it or any of its assets;

        (c)   all governmental and other consents that are required to have been obtained by it with respect to this Agreement have been obtained and are in full force and effect and all conditions of any such consents have been complied with;

        (d)   its obligations under this Agreement constitute its legal, valid and binding obligations, enforceable in accordance with their respective terms (subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors' rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement is sought in a proceeding in equity or at law));

        (e)   each of it and its Affiliates is not in possession of any material nonpublic information regarding Company or the Shares; and

        (f)    it is not entering into this Agreement or purchasing to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Securities Exchange Act of 1934, as amended.

        6.    Representations and Warranties of Dealer.    Dealer represents and warrants to Company on the date hereof that:

        (a)   it has the power to execute this Agreement and any other documentation relating to this Agreement to which it is a party, to deliver this Agreement and to perform its obligations under this Agreement and has taken all necessary action to authorize such execution, delivery and performance;

2

---

        (b)   such execution, delivery and performance do not violate or conflict with any law applicable to it, any provision of its constitutional documents, any order or judgment of any court or other agency of government applicable to it or any of its assets or any material contractual restriction binding on or affecting it or any of its assets;

        (c)   all governmental and other consents that are required to have been obtained by it with respect to this Agreement have been obtained and are in full force and effect and all conditions of any such consents have been complied with; and

        (d)   its obligations under this Agreement constitute its legal, valid and binding obligations, enforceable in accordance with their respective terms (subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors' rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement is sought in a proceeding in equity or at law)).

        7.    Account for Payment to Company:    

        8.    Governing Law.    This Agreement and any dispute arising hereunder shall be governed by and construed in accordance with the laws of the State of New York (without reference to choice of law doctrine).

        9.    Counterparts.    This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if all of the signatures thereto and hereto were upon the same instrument.

        10.    No Reliance, etc.    Company confirms that it has relied on the advice of its own counsel and other advisors (to the extent it deems appropriate) with respect to any legal, tax, accounting, or regulatory consequences of this Agreement, that it has not relied on Dealer or its Affiliates in any respect in connection therewith, and that it will not hold Dealer or its Affiliates accountable for any such consequences.

        11.    Agreements and Acknowledgements Regarding Hedging.    Company acknowledges and agrees that:

        (a)   on the Averaging Date, Dealer and its Affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to this Agreement;

        (b)   Dealer and its Affiliates also may be active in the market for Shares other than in connection with hedging activities in relation to this Agreement;

        (c)   Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in Company's securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the VWAP Price; and

        (d)   any market activities of Dealer and its Affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the VWAP Price, each in a manner that may be adverse to Company.

        12.    Indemnification.    In the event that Dealer or any of its Affiliates becomes involved in any capacity in any action, proceeding or investigation brought by or against any person in connection with any matter referred to in this Agreement, Company shall reimburse Dealer or such Affiliate for its reasonable legal and other out-of-pocket expenses (including the reasonable cost of any investigation and preparation) incurred in connection therewith within 90 days of receipt of written notice of such expenses, and shall indemnify and hold Dealer or such Affiliate harmless against any losses, claims, damages or liabilities to which Dealer or such Affiliate is subject to in connection with any such action, proceeding or investigation; provided, however, Company shall not indemnify Dealer or its Affiliates for any such losses, claims, damages, liabilities or expenses that result from, or relate to, the willful misconduct, fraud, gross negligence or bad faith of, or violation of applicable law or breach of this Agreement by, Dealer or any of its affiliates. If for any reason the foregoing indemnification is unavailable to Dealer or such Affiliate or insufficient to hold it harmless, then Company shall contribute to the amount paid or payable by Dealer or such Affiliate

as a result of such losses, claims, damages or liabilities (i) in such proportion as is reasonably appropriate to reflect the relative benefits received by Company on the one hand and Dealer or such Affiliate on the other hand in the matters contemplated by this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is reasonably appropriate to reflect not only the relative benefits received by Company on the one hand and Dealer or such Affiliate on the other hand in the matters contemplated by this Agreement but also the relative fault of Company and Dealer or such Affiliate with respect to such losses, claims, damages or liabilities and any other relevant equitable considerations. The reimbursement, indemnity and contribution obligations of Company under this Section 12 shall be in addition to any liability that Company may otherwise have, shall extend upon the same terms and conditions to the partners, directors, officers, agents, employees and controlling persons (if any), as the case may be, of Dealer and its Affiliates and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of Company, Dealer, any such Affiliate and any such person. Company also agrees that neither Dealer nor any of such Affiliates, partners, directors, officers, agents, employees or controlling persons shall have any liability to Company for or in connection with any matter referred to in this Agreement except to the extent that any losses, claims, damages, liabilities or expenses incurred by Company result from, or relate to, willful misconduct, fraud, the gross negligence or bad faith of, or violation of applicable law by, Dealer or any of its Affiliates or a breach by Dealer of any of its covenants or obligations hereunder. The foregoing provisions shall survive any termination or completion of the transactions contemplated by this Agreement.

        13.    No Other Changes.    Except as expressly set forth herein, all of the terms and conditions of the Additional Capped Call Confirmation shall remain in full force and effect and are hereby confirmed in all respects.
