PART I

ITEM 1. BUSINESS

Overview

Theravance Biopharma, Inc. (“we,” “our,” “Theravance Biopharma” or the “Company”) is a biopharmaceutical company primarily focused on the development and commercialization of medicines. Our focus is to deliver medicines that make a difference^® in people’s lives.

​

In pursuit of our purpose, we leverage decades of expertise, which has led to the development of the United States (“US”) Food and Drug Administration (the “FDA”) approved YUPELRI^® (revefenacin) inhalation solution indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (“COPD”). Ampreloxetine, our late-stage investigational once-daily norepinephrine reuptake inhibitor in development for the treatment of symptomatic neurogenic orthostatic hypotension (“nOH”) in patients with Multiple System Atrophy (“MSA”) has the potential to be a first in class therapy effective in treating a constellation of cardinal symptoms in MSA patients.

​

2023 Significant Developments

​

YUPELRI Sales Growth

In 2023, YUPELRI experienced sales growth and reached all-time high yearly net sales and profitability. Through the combined commercialization efforts with our partner Viatris Inc. (“Viatris”), total YUPELRI net sales increased by 9% to $221.0 million in 2023 compared to 2022. Hospital volumes, which we are directly responsible for, grew 46% in 2023 compared to 2022 and was a meaningful contributor to YUPELRI’s overall net sales growth for the year.

​

Initiation of Ampreloxetine New Phase 3 Clinical Study

In the first quarter of 2023, we initiated the ampreloxetine new Phase 3 clinical study (CYPRESS) in MSA patients with symptomatic nOH, using the Orthostatic Hypotension Symptom Assessment Scale (“OHSA”) composite score as the primary endpoint. In May 2023, we announced that the FDA granted Orphan Drug Designation status to ampreloxetine for the treatment of symptomatic nOH in patients with MSA. The study is currently enrolling patients with 42 clinical sites open across 11 countries, as of February 26, 2024.

​

Capital Return Program

In 2023, we repurchased 18.63 million of our shares on the open market at a weighted average cost of $10.551 per share for an approximate aggregate cost of $196.6 million, excluding fees and expenses. Since the inception of the capital return program in September 2022 through its completion in early January 2024, we repurchased a total of 31.41 million shares at a weighted average cost of $10.354 per share for an approximate aggregate cost of $325.3 million which reduced our shares by 37% since the inception of the capital return program.

​

Discontinued Investment in Research

In February 2023, we announced that we discontinued our research activities, including the inhaled Janus kinase (JAK) inhibitor program, and prioritized our R&D resources toward the ampreloxetine Phase 3 study and the completion of the YUPELRI Peak Inspiratory Flow Rate (PIFR-2) Phase 4 study. As a result of halting further investment in research activities, our headcount was reduced by approximately 17% in March 2023. We plan to seek a partnership to continue progression of our inhaled JAK inhibitor program.

​

Board Governance Changes

In 2023, we appointed three new independent directors reflecting our ongoing commitment to bringing new perspectives and complementary skills to the Company. In addition, we put forth a proposal to declassify the board of the directors over time which was approved at our May 2023 Annual General Meeting of Shareholders.

Core Program Updates

YUPELRI (revefenacin) Inhalation Solution

​

YUPELRI (revefenacin) inhalation solution is a once-daily, nebulized long-acting muscarinic antagonist (“LAMA”) approved for the maintenance treatment of COPD in the US. LAMAs are recognized by international COPD treatment guidelines as a cornerstone of maintenance therapy for COPD, regardless of severity of disease. Our market research indicates there is an enduring population of COPD patients in the US that either need or prefer nebulized delivery for maintenance therapy. The stability of revefenacin in both metered dose inhaler and dry powder inhaler (“MDI/DPI”) formulations suggests that revefenacin could also serve as a foundation for novel handheld combination products.

​

Table of Contents

We co-developed YUPELRI with our collaboration partner, Viatris Inc. Under the terms of the Viatris Development and Commercialization Agreement (the “Viatris Agreement”), we led the US Phase 3 development program for YUPELRI in COPD, and Viatris was responsible for reimbursement of our costs related to the registrational program up until the approval of the first new drug application, after which costs were shared. YUPELRI was approved by the FDA for the maintenance treatment of patients with COPD in November 2018. In the US, Viatris is leading the commercialization of YUPELRI, and we co-promote the product under a profit and loss sharing arrangement (65% to Viatris; 35% to us). Outside the US (excluding China and adjacent territories), Viatris is responsible for development and commercialization and will pay us a tiered royalty on net sales at percentage royalty rates ranging from low double-digits to mid-teens. We retain worldwide rights to revefenacin delivered through other dosage forms, such as a MDI/DPI.

​

In 2019, we granted Viatris exclusive development and commercialization rights to nebulized revefenacin in China and adjacent territories, which include the Hong Kong SAR, the Macau SAR, and Taiwan, (collectively, the “China Region”) and we are eligible to receive low double-digit tiered royalties on net sales of nebulized revefenacin, if approved. As noted above, Viatris is responsible for all aspects of development and commercialization of nebulized revefenacin in the China Region, including pre- and post-launch activities and product registration and all associated costs.

​

Under the terms of the Viatris Agreement, as amended, as of December 31, 2023, we were eligible to receive from Viatris potential global development, regulatory and sales milestone payments (excluding the China Region) of up to $205.0 million in the aggregate with $160.0 million associated with YUPELRI monotherapy and $45.0 million associated with future potential combination products. Of the $160.0 million associated with monotherapy, $10.0 million relates to regulatory actions in the EU and $150.0 million relates to sales milestones based on achieving certain levels of annual US net sales as follows:

​

​

As of December 31, 2023, we were also eligible to receive additional potential development and sales milestones of up to $52.5 million related to Viatris’ development and commercialization of nebulized revefenacin in the China Region with $45.0 million associated with YUPELRI monotherapy and $7.5 million associated with future potential combination products. Of the $45.0 million associated with monotherapy, $7.5 million relates to regulatory approval in the China Region and $37.5 million relates to sales milestones based on achieving certain levels of cumulative net sales in the China Region as follows:

​

​

With respect to the China Region royalties, we are eligible to receive low double-digit tiered royalties on net sales of nebulized revefenacin as follows:

In November 2023, we learned that Viatris’ Phase 3 study of YUPELRI in China was positive, and the data were consistent with previous findings of YUPELRI’s strong efficacy. Viatris plans to move forward with a registrational filing for YUPELRI in China in mid-2024.

​

In August 2021, we announced that in collaboration with our partner Viatris, we were initiating a Phase 4 study comparing improvements in lung function in adults with severe to very severe COPD and suboptimal inspiratory flow rate following once-daily treatment with either revefenacin (YUPELRI) delivered via standard jet nebulizer or tiotropium delivered via a dry powder inhaler (Spiriva^® HandiHaler^®). This study was aimed at helping to better inform decisions when physicians are designing a personalized COPD treatment plan with patients. We agreed to pay 35% of the Phase 4 study costs, and Viatris agreed to pay 65% of the Phase 4 study costs. The first patient for the Phase 4 study was enrolled in January 2022. In January 2024, we announced that the Phase 4 study did not show a statistically significant difference between YUPELRI and Spiriva HandiHaler on the primary endpoint, change from baseline in trough forced expiratory volume in one second (FEV₁) at day 85. While the primary endpoint in the Phase 4 study was not met, YUPELRI demonstrated an efficacy and safety profile consistent with its performance in other clinical studies.

​

While Viatris records total YUPELRI net sales, we are entitled to a 35% share of the net profit (loss). Our implied 35% share of total YUPELRI net sales is presented below:

​

​

Ampreloxetine (TD-9855)

​

Ampreloxetine is an investigational, once-daily norepinephrine reuptake inhibitor (“NRI”) that we are developing for the treatment of Multiple System Atrophy (“MSA”) patients with symptomatic neurogenic orthostatic hypotension (“nOH”). nOH is caused by primary autonomic failure conditions and the majority of patients with MSA experience symptoms of nOH. Ampreloxetine has high affinity for binding to the norepinephrine (“NE”) transporter. By blocking the action of the NE transporter, ampreloxetine causes an increase in extracellular concentrations of norepinephrine. Ampreloxetine is wholly owned by Theravance Biopharma.

​

Based on positive results from a small exploratory Phase 2 study in nOH and discussions with the FDA, we advanced ampreloxetine into a Phase 3 program. We announced the initiation of patient dosing in study in early 2019. The Phase 3 program consisted of two pivotal studies and one non-pivotal study. The first pivotal study (SEQUOIA), a four-week, randomized double-blind, placebo-controlled study, was designed to evaluate the efficacy and safety of ampreloxetine in Parkinson’s disease (“PD”), pure autonomic failure (“PAF”) and MSA patients with symptomatic nOH. The second pivotal study (REDWOOD), a four-month open label study followed by a six-week randomized withdrawal phase was designed to evaluate the durability of the same patient group’s response to ampreloxetine. The protocol for the pivotal studies stipulated an enrollment threshold of 40% MSA patients based on the hypothesis ampreloxetine would work the best in patients with MSA because they have more intact nerves on which ampreloxetine can exert its effect, relative to the other patient types in the study. The third, non-pivotal study (OAK), was a three and half year long-term extension study.

​

In September 2021, we reported that the SEQUOIA Phase 3 clinical study did not meet its primary endpoint. Most treatment-related adverse events were mild or moderate in severity. Serious adverse events occurred in two patients on placebo and four on ampreloxetine, none of which were considered related to the study drug. No deaths were reported, and there was no signal for supine hypertension.

​

In April 2022, we reported that the REDWOOD Phase 3 clinical study did not meet its primary endpoint as the results were not statistically significant for the overall population of patients which included patients with PD, PAF, and MSA. The pre-specified subgroup analysis by disease type suggested that the average benefit seen in patients receiving ampreloxetine was largely driven by a benefit to MSA patients. The benefit to MSA patients in the study was observed in multiple endpoints including Orthostatic Hypotension Symptom Assessment Scale (“OHSA”) composite, Orthostatic Hypotension Daily Activities Scale (“OHDAS”) composite, Orthostatic Hypotension Questionnaire (“OHQ”) composite

and OHSA #1. Throughout the study, there was no indication of worsening of supine hypertension among any of the patient sub-groups. Data suggest that ampreloxetine was well-tolerated and no new safety signals were identified among any of the patient sub-groups.

​

In June 2022, we held a Type C meeting with the FDA. From this meeting, we aligned on a path to a New Drug Application (“NDA”) filing with one additional Phase 3 clinical study (CYPRESS) in MSA patients with symptomatic nOH, using the OHSA composite score as the primary endpoint. This Phase 3 study was initiated in the first quarter of 2023, and the study is currently open to recruitment with the expectation of enrolling the final patient into the open label period of the study in the second half of 2024. In May 2023, we announced that the FDA granted Orphan Drug Designation status to ampreloxetine for the treatment of symptomatic nOH in patients with MSA. 

​

In July 2022, Royalty Pharma Investments 2019 ICAV (“Royalty Pharma”) agreed to invest up to $40.0 million to advance the development of ampreloxetine in MSA in exchange for unsecured low single-digit royalties. Royalty Pharma’s $40.0 million investment in ampreloxetine included a $25.0 million upfront payment received in July 2022 and an additional $15.0 million payment upon the first regulatory approval of ampreloxetine. In exchange, Royalty Pharma will receive future unsecured royalties of 2.5% on annual ampreloxetine global net sales up to $500.0 million and 4.5% on annual global net sales over $500.0 million. If ampreloxetine regulatory approval is not achieved or if ampreloxetine sales are never recognized, the amounts invested by Royalty Pharma would not be repaid by us.

​

Skin-selective Pan-JAK inhibitor Program

​

In December 2019, we entered into a global license agreement with Pfizer Inc. (“Pfizer”) for our preclinical skin-selective, locally acting pan-JAK inhibitor program (the “Pfizer Agreement”). The compounds in this program are designed to target validated pro-inflammatory pathways and are specifically designed to possess skin-selective activity with minimal systemic exposure. Under the Pfizer Agreement, Pfizer had an exclusive license to develop, manufacture and commercialize certain compounds for all uses other than gastrointestinal, ophthalmic, and respiratory applications. We received an upfront cash payment of $10.0 million in 2019, and in March 2022, we received a $2.5 million development milestone payment from Pfizer for the first patient dosed in a Phase 1 clinical trial of the skin-selective pan-JAK inhibitor program. In June 2023, we received notice from Pfizer terminating the Pfizer Agreement, effective as of October 7, 2023, at which time the skin-selective pan-JAK inhibitor program was returned to us.

​

Economic Interests and Other Assets

​

Mid- and Long-Term Economic Interest in TRELEGY^®

In July 2022, we completed the sale of all of our equity interests in Theravance Respiratory Company, LLC (“TRC”) representing our 85% economic interest in the sales-based royalty rights on worldwide net sales of GSK plc's (“GSK”) TRELEGY ELLIPTA (“TRELEGY”) to Royalty Pharma for approximately $1.1 billion in upfront cash while retaining future value through the right to receive contingent milestone payments and certain outer year-royalties (the “TRELEGY Royalty Transaction”).

​

From and after January 1, 2023, for any calendar year starting with the year ended December 31, 2023 and ending with the year December 31, 2026, upon certain milestone minimum royalty amounts for TRELEGY being met, Royalty Pharma is obligated to make certain cash payments to us (the “Milestone Payment(s)”). As of January 1, 2024, a total of $200.0 million in potential Milestone Payments remain available to us. For the next potential Milestone Payment, we are eligible to receive either (i) $25.0 million if Royalty Pharma receives $240.0 million or more in royalty payments from GSK with respect to 2024 TRELEGY global net sales, which we would expect to occur in the event TRELEGY global net sales are approximately $2.86 billion; or (ii) $50.0 million if Royalty Pharma receives $275.0 million or more in royalty payments from GSK with respect to 2024 TRELEGY global net sales, which we would expect to occur in the event TRELEGY global net sales exceed approximately $3.21 billion. Fourth quarter of 2023 global net sales were $737.0 million which represented an increase of 35% year-over-year, and total 2023 global net sales were $2.7 billion which represented an increase of 28% year-over-year.

​

In addition to potential Milestone Payments, we will receive from Royalty Pharma 85% of the royalty payments on TRELEGY payable (a) for sales or other activities occurring on and after January 1, 2031 related to TRELEGY in the

8

Table of Contents

US, and (b) for sales or other activities occurring on and after July 1, 2029 related to TRELEGY outside of the US. US TRELEGY royalties payable to us by Royalty Pharma are expected to end in late 2032, and ex-US royalties are expected to end in the mid-2030s and are country specific. Royalty rates are upward tiering from 6.5% to 10% and based on total annual net sales.

​

The following information regarding the TRELEGY program is based solely upon publicly available information and may not reflect the most recent developments under the programs.

​

TRELEGY provides the activity of an inhaled corticosteroid (FF) plus two bronchodilators (UMEC, a LAMA, and VI, a long-acting beta2 agonist, or LABA) in a single delivery device administered once-daily. TRELEGY is approved for use in the US, European Union (“EU”), and other countries for the long-term, once-daily, maintenance treatment of patients with COPD. Additionally, the FDA approved an sNDA for the use of TRELEGY to treat asthma in adults in September 2020 making TRELEGY the first once-daily single inhaler triple therapy for the treatment of both asthma and COPD in the US. GSK has obtained approval for the asthma indication in ten additional markets. TRELEGY is currently expected to generate global peak sales of $3.7 billion in 2027 according to consensus estimates. Over the past three years, TRELEGY has shown substantial growth, with global net sales increasing annually from $661.4 million in 2019 to $2.7 billion in 2023.

​

See “Risk Factors—We do not control the commercialization of TRELEGY; accordingly, our receipt of Milestone Payments and receipt of the value we currently anticipate from the Outer Years Royalty will depend on, among other factors, GSK’s ability to further commercialize TRELEGY” for additional information.

​

Development Projects

Our focus remains on near-term value opportunities which consists of executing our ampreloxetine registration Phase 3 study (CYPRESS) and preparing for the NDA filing process. In February 2023, as part of our 2023 Strategic Actions, we announced the decision to discontinue research activities including our inhaled JAK program, including nezulcitinib, a nebulized, lung-selective JAK inhibitor positioned for the treatment of acute and chronic lung diseases.

​

Our Strategy

Our focus is to deliver medicines that make a difference^® in people's lives. In pursuit of our purpose, we leverage decades of expertise, which has led to the development of FDA-approved YUPELRI^® (revefenacin) inhalation solution indicated for the maintenance treatment of patients with COPD. Ampreloxetine, our late-stage investigational norepinephrine reuptake inhibitor in development for symptomatic nOH, has the potential to be a first in class therapy effective in treating a constellation of cardinal symptoms in MSA patients. We are committed to creating/driving shareholder value.

​

We follow these core guiding principles in our mission to drive value creation:

​

We manage our pipeline with the goal of optimizing program value and allocation of resources. We employ multiple strategies for commercialization of our products. Our approach may involve retaining product rights and marketing a product independently in the US or we may partner a product to extend our commercial reach, to expand our geographic reach, and/or to manage the financial risk associated with the program. Alternatively, we may monetize or divest an asset that we designate as outside our core business, where we believe the program is optimized by leveraging partner capabilities and removing or limiting our research and development costs.

​

Table of Contents

Manufacturing

We rely on a network of third-party contract manufacturing organizations to produce the active pharmaceutical ingredients (“API”) and drug products required for our clinical trials. We believe that we and our partners have in-house expertise to manage this network of third-party manufacturers, and we believe that we will be able to continue to negotiate third-party manufacturing arrangements on commercially reasonable terms and that it will not be necessary for us to rely on internal manufacturing capacity in order to develop or, potentially, commercialize our products. However, if we are unable to obtain contract manufacturing or obtain such manufacturing on commercially reasonable terms, or if manufacturing is interrupted at one of our suppliers, whether due to regulatory or other reasons, we may not be able to develop or commercialize our products as planned.

​

Any inability to acquire sufficient quantities of API or drug product in a timely manner from current or future sources could disrupt our development programs, the conduct of future clinical trials or our commercialization efforts. For more information, see the risk factor under the heading “There is a single source of supply for a number of our product candidates and for YUPELRI, and our business will be harmed if any of these single-source manufacturers are not able to satisfy demand and alternative sources are not available” of this Annual Report on Form 10-K.

​

Government Regulation

The development and commercialization of pharmaceutical products and our product candidates by us, our collaboration partners and licensees, and those commercializing products in which we have an economic interest, such as GSK, are subject to extensive regulation by governmental authorities in the US and other countries. Before marketing in the US, any medicine must undergo rigorous preclinical studies and clinical studies and an extensive regulatory approval process implemented by the FDA under the Federal Food, Drug, and Cosmetic Act. Outside the US, the ability to market a product depends upon receiving a marketing authorization from the appropriate regulatory authorities which are subject to equally rigorous regulatory obligations. The requirements governing the conduct of clinical studies, marketing authorization, pricing and reimbursement vary widely from country to country. In any country, however, the commercialization of pharmaceutical products is permitted only if the appropriate regulatory authority is satisfied that we have presented adequate evidence of the safety, quality and efficacy of the product.

​

Before commencing clinical studies in humans in the US, we must submit to the FDA an investigational new drug application (“IND”) that includes, among other things, the general investigational plan and protocols for specific human studies and the results of preclinical studies. An IND will go into effect 30 days following its receipt by the FDA unless the FDA issues a clinical hold. Once clinical studies have begun under the IND, they are usually conducted in three phases and under FDA oversight. These phases generally include the following:

​

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

​

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

​

Phase 3. Phase 3 clinical trials are undertaken to further evaluate dosage, clinical efficacy, potency and safety in an expanded patient population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit profile of the product and provide an adequate basis for product labeling.

​

The results of product development, preclinical studies and clinical studies must be submitted to the FDA as part of an NDA. The NDA also must contain extensive manufacturing information, and under the Pediatric Research Equity Act (“PREA”), certain applications for approval must also include an assessment, generally based on clinical study data, of the safety and effectiveness of the subject drug in relevant pediatric populations. The submission of an NDA generally requires payment of a substantial user fee to the FDA under the Prescription Drug User Fee Act (“PDUFA”), subject to certain limited deferrals, waivers and reductions. FDA’s PDUFA performance goal is to review and act on 90 percent of priority new molecular entity (“NME”) NDA submissions within 6 months of the 60-day filing date, and to review and act on 90 percent of standard NME NDA submissions within 10 months of the 60-day filing

Table of Contents

date. The FDA may determine that a Risk Evaluation and Management Strategy (“REMS”) is necessary to ensure that the benefits of a product outweigh its risks. At the end of the review period, the FDA communicates either approval of the NDA or issues a complete response letter (“CRL”) listing the application’s deficiencies. The CRL may require additional testing or information, including additional pre-clinical or clinical data, for the FDA to reconsider the application. Even if such additional information and data are submitted, the FDA may decide that the NDA still does not meet the standards for approval. Data from clinical trials are not always conclusive and the FDA may interpret data differently than the sponsor. FDA approval of any application may include many delays or never be granted. If FDA grants approval, an approval letter authorizes commercial marketing of the product candidate with specific prescribing information for specific indications. Post-approval modifications to the drug, such as changes in indications, labeling, or manufacturing processes or facilities, may require a sponsor to develop additional data or conduct additional pre-clinical studies or clinical trials, to be submitted in a new or supplemental NDA, which would require FDA approval.

​

If an application is approved, drug products are subject to continuing regulation by the FDA, and the FDA may withdraw the product approval if compliance with 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, sometimes referred to as Phase 4 studies, to monitor the safety and effectiveness 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 require changes to a product’s approved labeling, including the addition of new warnings and contraindications, or the implementation of other risk management measures, including distribution-related restrictions, if there are new safety information developments, suspend or delay issuance of approvals, seize products, withdraw approvals, enjoin violations, and initiate criminal prosecution.

​

If regulatory approval for a medicine is obtained, the clearance to market the product will be limited to those diseases and conditions approved by FDA and for which the medicine was shown to be effective, as demonstrated through clinical studies and specified in the medicine’s labeling. 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, carefully monitoring manufacturers’ compliance with its current Good Manufacturing Practice (“cGMP”) regulations by conducting regular, periodic visits to re-inspect equipment, facilities, and processes following the initial approval of a product. Failure to comply with applicable cGMP requirements and conditions of product approval may lead the FDA to take enforcement actions or seek sanctions, including fines, issuance of warning letters, civil penalties, injunctions, suspension of manufacturing operations, operating restrictions, withdrawal of FDA approval, seizure or recall of products, and criminal prosecution. 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 fines, issuance of warning letters, civil penalties, injunctions, suspension of manufacturing operations, operating restrictions, costly recalls, withdrawal of FDA approval, and criminal prosecution.

​

Additionally, the FDA and other federal regulatory agencies closely regulate the marketing and promotion of drugs through, among other things, standards and regulations for direct-to-consumer advertising, advertising and promotion to healthcare professionals, communications regarding unapproved uses, industry-sponsored scientific and educational activities, and promotional activities involving the Internet. A product cannot be promoted before it is approved. After approval, product promotion can include only those claims relating to safety and effectiveness that are consistent with the labeling approved by the FDA. Healthcare providers are permitted to prescribe drugs for “off-label” uses - that is, uses not approved by the FDA and not described in the product’s labeling - because the FDA does not regulate the practice of medicine. However, FDA regulations impose restrictions on manufacturers’ communications regarding off-label uses. Broadly speaking, a manufacturer may not promote a drug for off-label use, but under certain conditions may engage in non-promotional, balanced, scientific communication regarding off-label use. Failure to comply with applicable FDA requirements and restrictions in this area may subject a company to adverse publicity and enforcement action by the FDA, the Department of Justice, or the Office of the Inspector General of the Department of Health and Human Services, as well as state authorities. This could subject a company to a range of penalties that could have a significant commercial impact, including civil and criminal fines and agreements that materially restrict the manner in which a company promotes or distributes a drug.

​

We, our collaboration partners and licensees are also subject to various laws and regulations regarding laboratory practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous substances in connection with our drug development. 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 initiate 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 US, the ability to market 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.

​

United States Healthcare Reform

The Patient Protection and Affordable Care Act, as amended (the “Healthcare Reform Act”), substantially changed the way healthcare is financed by both governmental and private insurers, and impacts pricing and reimbursement of YUPELRI and the marketed drugs with respect to which we are entitled to royalty or similar payments, and related commercial operations. Certain provisions of the Healthcare Reform Act have been subject to judicial challenges as well as efforts to modify them or to alter their interpretation or implementation. We expect that the Healthcare Reform Act, its implementation, efforts to modify, or invalidate, the Healthcare Reform Act or portions thereof, or its implementation, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect on our industry generally and on the ability of us, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties to maintain or increase sales of our existing products or to successfully commercialize our product candidates, if approved. For more information, see the risk factor under the heading “Changes in healthcare law and implementing regulations, including government restrictions on pricing and reimbursement, as well as healthcare policy and other healthcare payor cost-containment initiatives, may negatively impact us, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties” of this Annual Report on Form 10-K.

​

Pharmaceutical Pricing

We participated in and had certain price reporting obligations under the Medicaid Drug Rebate and other programs and we remain responsible for data reported under those programs in past quarters, as described in greater detail under the risk factor “If we failed to comply with our reporting and payment obligations under the Medicaid Drug Rebate program or other governmental pricing programs, we could be subject to additional reimbursement requirements, penalties, sanctions and fines, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects” of this Annual Report on Form 10-K.

​

Our ability, and the ability of our collaboration partners, licensees, or those commercializing products with respect to which we have an economic interest or right to receive royalties to commercialize our products successfully, and our ability to attract commercialization partners for our products, depends in significant part on the availability of adequate financial coverage and reimbursement from third-party payors, including, in the US, governmental payors such as the Medicare and Medicaid programs, managed care organizations, and private health insurers. The Inflation Reduction Act of 2022 (the “IRA”) establishes a new manufacturer discount program, Part B and Part D inflation rebates, and a Drug Price Negotiation Program under which the prices for Medicare units of certain high Medicare spend drugs without generic or biosimilar competition will be capped by reference to, among other things, a specified non-federal average manufacturer price, with negotiated prices set to take effect starting in 2026. Whether any of our products are selected for negotiation for a given year will depend on whether they are at least 7 years post-approval/licensure; whether they meet any of the exclusions from eligibility for selection for negotiation, such as the exclusion of certain orphan drugs; their expenditures under Medicare Part B or Part D during a statutorily specified period; and whether a generic of the product has been determined to have come to market. Ampreloxetine received an Orphan Drug Designation status from the FDA, which should mean it will not be selected for negotiation, assuming it continues to meet all other criteria for the exclusion from eligibility for selection. However, our understanding of whether and when our products are likely to be subject to selection for negotiation could evolve as the Drug Price Negotiation Program is implemented. We further expect continued scrutiny on pricing from Congress, agencies, and

12

Table of Contents

other bodies with respect to drug pricing. The reimbursement environment is described in greater detail under the risk factor “Changes in healthcare law and implementing regulations, including government restrictions on pricing and reimbursement, as well as healthcare policy and other healthcare payor cost-containment initiatives, may negatively impact us, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties” of this Annual Report on Form 10-K.

​

Coverage and Reimbursement

Market acceptance and sales of any one or more of our product candidates will depend on reimbursement policies and may be affected by future healthcare reform measures in the US. Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we obtain regulatory approval. In the US and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part on the availability of reimbursement from third-party payers. Third-party payers include government health administrative authorities, managed care providers, private health insurers and other organizations. The process for determining whether a payer will provide coverage for a drug product may be separate from the process for setting the price or reimbursement rate that the payer will pay for the drug product. Third-party payers may limit coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drugs for a particular indication. Third-party payers are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of our products, in addition to the costs required to obtain FDA approvals. Any approved products we commercialize may not be considered by payers to be medically necessary or cost-effective for particular diseases or conditions. A payer’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.

​

Fraud and Abuse Laws

Our interactions and arrangements with customers and third-party payors are subject to applicable US federal and state fraud and abuse laws and equivalent third country laws. These laws and the related risks are described in greater detail under the risk factor “Our relationships with customers and third-party payors are subject to applicable anti-kickback, fraud and abuse, transparency and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, exclusion, contractual damages, reputational harm and diminished profits and future earnings” of this Annual Report on Form 10-K.

​

Data Privacy and Protection

We are subject to laws and regulations that address privacy and data security. In the US, numerous federal and state laws and regulations, including state data breach notification laws, state health information and/or genetic privacy laws, and federal and state consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act (“FTC Act”)), govern the collection, use, disclosure, and protection of health-related and other personal information. Similar obligations apply outside of the US. For example, the General Data Protection Regulation (“GDPR”) amplified existing data protection obligations in the EU. These laws and related risks are described in greater detail under the risk factor “If we fail to comply with data protection laws and regulations, we could be subject to government enforcement actions (which could include civil or criminal penalties), private litigation and/or adverse publicity, which could negatively affect our operating results and business” of this Annual Report on Form 10-K.

​

Patents and Proprietary Rights

We will be able to protect our technology from unauthorized use by third parties only to the extent that our technology is covered by valid and enforceable patents or is effectively maintained as trade secrets. Our success in the future will depend in part on obtaining patent protection for our product candidates. Accordingly, patents and other proprietary rights are essential elements of our business. Our policy is to seek patent protection in the US and selected foreign countries for novel technologies, including compositions of matter that are commercially important to the development of our business. Issued US and foreign patents generally expire 20 years after their filing date. For proprietary know-how that is not patentable, processes for which patents are difficult to enforce and any other elements

13

Table of Contents

of our drug discovery process that involve proprietary know-how and technology that is not covered by patent applications, we rely on trade secret protection and confidentiality agreements to protect our interests. We require all of our employees, consultants, and advisors to enter into confidentiality agreements. Where it is necessary to share our proprietary information or data with outside parties, our policy is to make available only that information and data required to accomplish the desired purpose and only pursuant to a duty of confidentiality on the part of those parties.

​

As of December 31, 2023, we owned a total of 176 issued US patents and 1,002 granted foreign patents, as well as additional pending US patent applications and foreign patent applications. The claims in these various patents and patent applications are typically directed to compositions of matter, including claims covering product candidates, crystalline forms, lead compounds and key intermediates, pharmaceutical compositions, methods of use and/or processes for making our compounds. Our patents and patent applications are also directed to other inventions made during the research and development process. In particular, our wholly-owned subsidiary Theravance Biopharma R&D IP, LLC owns the following US patents that are listed in the FDA Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book) for YUPELRI (revefenacin) inhalation solution: US Patent No. 7,288,657, expiring on December 23, 2025; US Patent No. 7,491,736, expiring March 10, 2025; US Patent No. 7,521,041, expiring March 10, 2025; US Patent No. 7,550,595, expiring March 10, 2025; US Patent No. 7,585,879, expiring March 10, 2025; US Patent No. 7,910,608, expiring March 10, 2025; US Patent No. 8,034,946, expiring March 10, 2025; US Patent No. 8,053,448, expiring March 10, 2025; US Patent No. 8,273,894, expiring March 10, 2025; US Patent No. 8,541,451, expiring August 25, 2031; US Patent No. 9,765,028, expiring July 14, 2030; US Patent No. 10,106,503, expiring March 10, 2025; US Patent No. 10,343,995, expiring March 10, 2025; US Patent No. 10,550,081, expiring July 14, 2030; US Patent No. 11,008,289, expiring July 14, 2030; US Patent No. 11,247,969, expiring March 10, 2025; US Patent 11,484,531, expiring October 23, 2039; US Patent 11,691,948, expiring July 14, 2030; and US Patent 11,858,898, expiring July 14, 2030 (each of the aforementioned expiration dates not including any patent term extensions that may be available under the Drug Price Competition and Patent Term Restoration Act of 1984). Thus, the last to expire patent currently listed in the Orange Book for YUPELRI (revefenacin) inhalation solution expires on October 23, 2039. On December 19, 2018, we filed patent term extension (“PTE”) applications in the US Patent and Trademark Office (“USPTO”) for US Patent Nos. 7,288,657 and 7,585,879. These PTE applications are currently pending and, if granted, we will be permitted to extend the term of one of these patents for the period determined by the USPTO.

​

The patent rights relating to YUPELRI (revefenacin) inhalation solution currently consist of issued US patents, pending US patent applications and certain counterpart patents and patent applications in a number of jurisdictions, including Europe and China.

​

Additionally, some of our patents and patent applications are directed to products in development. Our patent rights relating to ampreloxetine include an issued US composition of matter patent that expires in 2030 and an issued US method of treatment patent that expires in 2037 (in each case, not including any patent term extensions that may be available under the Drug Price Competition and Patent Term Restoration Act of 1984). The patent portfolio for this development product includes additional pending patent applications and granted patents in a number of jurisdictions. 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 potentially 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.

​

Patent Term Restoration, Regulatory Exclusivities, and Hatch-Waxman Litigation

Depending upon the timing, duration, and specifics of FDA approval of our product candidates, some of our US patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of

14

Table of Contents

an IND and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application, except that the period is reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug is eligible for the extension, and the extension must be applied for prior to expiration of the patent and within 60 days of approval. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.

​

The Hatch-Waxman Act also provides periods of regulatory exclusivity for products that would serve as a reference listed drug, or RLD, for an abbreviated new drug application, or ANDA, or application submitted under section 505(b)(2) of the FDCA, or 505(b)(2) application. If a product is a new chemical entity, or NCE — generally meaning that the active moiety has never before been approved in any drug — there is a period of five years from the product’s approval during which the FDA may not accept for filing any ANDA or 505(b)(2) application for a drug with the same active moiety. An ANDA or 505(b)(2) application may be submitted after four years, however, if the sponsor of the application makes a “Paragraph IV” certification stating that one or more of the Orange Book listed patents are invalid or will not be infringed by the applicant’s product.

​

A product, if not an NCE, or a new product use may instead qualify for a three-year period of exclusivity if the NDA contains new clinical data (other than bioavailability studies), derived from studies conducted by or for the sponsor, that were necessary for approval. In that instance, the exclusivity period does not preclude filing or review of an ANDA or 505(b)(2) application; rather, the FDA is precluded from granting final approval to the ANDA or 505(b)(2) application until three years after approval of the RLD. Additionally, the exclusivity applies only to the conditions of approval that required submission of the clinical data.

​

Once the FDA accepts for filing an ANDA or 505(b)(2) application containing a Paragraph IV certification, the applicant must within 20 days provide notice to the RLD NDA holder and patent owner that the application has been submitted and provide the factual and legal basis for the applicant’s assertion that the patent is invalid or not infringed. If the NDA holder or patent owner files suit against the ANDA or 505(b)(2) applicant for patent infringement within 45 days of receiving the Paragraph IV notice, the FDA is prohibited from approving the ANDA or 505(b)(2) application for a period of 30 months or the resolution of the underlying suit, whichever is earlier. If the RLD has NCE exclusivity and the notice is given and suit filed during the fifth year of exclusivity, the regulatory stay extends until 7.5 years after the RLD approval. The FDA may approve the proposed product before the expiration of the regulatory stay if a court finds the patent invalid or not infringed or if the court shortens the period because the parties have failed to cooperate in expediting the litigation.

​

During January 2023, we received notice from Accord Healthcare, Inc.; Cipla USA, Inc. and Cipla Limited; Eugia Pharma Specialties Ltd.; Lupin Inc.; Mankind Pharma Ltd.; Orbicular Pharmaceutical Technologies Private Limited; and Teva Pharmaceuticals, Inc. (collectively, the “generic companies”), that they have each filed with FDA an ANDA, for a generic version of YUPELRI. The notices from the generic companies each included a Paragraph IV certification with respect to five of our patents listed in FDA’s Orange Book for YUPELRI. The asserted patents relate generally to polymorphic forms of and a method of treatment using YUPELRI. In February 2023, we filed patent infringement suits against the generic companies in federal district court, which continue in the United States District Court for the District of New Jersey. That complaint alleges that by filing the ANDAs, the generic companies have infringed five of our Orange Book listed patents. We are seeking a permanent injunction to prevent the generic companies from introducing a generic version of YUPELRI that would infringe our patents. As a result of this lawsuit, a stay of approval through May 2026 will be imposed by FDA on the generic companies’ ANDAs pending any adverse court decision.

​

We have subsequently filed further complaints and amended complaints regarding newly-granted Orange Book listed patents, as well as certain non-Orange Book listed patents. These new complaints do not result in any further stay of approval by FDA.

​

As of February 28, 2024, we have settled all litigation with Accord Healthcare, Inc.; Lupin Pharmaceuticals, Inc.; Orbicular Pharmaceutical Technologies Private Limited; and Teva Pharmaceuticals, Inc. pursuant to individual agreements in which we granted these companies a royalty-free, non-exclusive, non-sublicensable, non-transferable license to manufacture and market their respective generic versions of YUPELRI inhalation solution in the US on or

15

Table of Contents

after the licensed launch date of April 23, 2039, subject to certain exceptions as is customary in these type of agreements. As required by law, the settlements are subject to review by the U.S. Department of Justice and the Federal Trade Commission. The patent litigation against the three remaining generic companies, along with certain affiliates, remains pending.

​

This litigation and the related risks are described in greater detail under the risk factor “Litigation to protect or defend our intellectual property or third-party claims of intellectual property infringement would require us to divert resources and may prevent or delay our drug discovery and development efforts” of this Annual Report on Form 10-K.

​

Competition

Our late-stage development programs, and the marketed products to which we are entitled to profit share revenue, royalty or similar payments are primarily focused on respiratory and neurological therapeutics. Our commercial infrastructure is focused primarily on the acute care setting. We expect that any medicines that we commercialize with our collaborative partners or on our own will compete with existing and future market-leading medicines.

​

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

​

YUPELRI (revefenacin) inhalation solution

YUPELRI competes predominately with short acting nebulized bronchodilators that are dosed three to four times per day. During 2023, Sunovion Pharmaceuticals Inc. voluntarily withdrew Lonhala^® Magnair^® (glycopyrrolate) from the US market due to limited utilization, leaving YUPELRI as the only approved nebulized LAMA as of December 31, 2023.

​

Verona Pharma plc’s ensifentrine, a first-in-class, selective inhaled dual inhibitor of PDE3 and PDE4 is expected to launch in the US in the second half of 2024. Nebulized ensifentrine has the potential to be complementary to YUPELRI given that it is another nebulized treatment for COPD.

​

Sanofi and Regeneron Pharmaceutical, Inc. are expecting US approval for their first-in-class, IL-4/IL-13 monoclonal antibody (mAb) Dupixent^® (dupilumab) for COPD in the second half of 2024. The expanded indication is expected to be a maintenance treatment for patients with moderate-to-severe COPD, who are uncontrolled with current SOC triple therapy (LAMA + LABA + ICS) and have evidence of Type 2 inflammation and frequent exacerbation history. Dupixent is currently indicated for atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis, eosinophilic esophagitis and prurigo nodularis.

​

Ampreloxetine norepinephrine reuptake inhibitor (“NRI”)

If successfully developed and approved, ampreloxetine would be expected to serve as the only safe, convenient, and durably effective treatment option for MSA patients with symptomatic nOH. While droxidopa is currently the sole product approved for nOH patients, it was approved to treat dizziness, lightheadedness, or the “feeling that you are about to black out” in adults who experience nOH and who have MSA or other conditions. Droxidopa has never demonstrated

16

Table of Contents

a durable effect on nOH symptoms including failure of a confirmatory study known as RESTORE which was required by the FDA as a condition of an accelerated approval. Northera^®, marketed by Lundbeck NA Ltd., is the branded version of droxidopa and became generic in 2021. Midodrine, which is approved for OH, is not indicated to improve symptoms of nOH. Both midodrine and droxidopa must be taken 3 times daily and carry a black box warning for its potential to lead to a “marked elevation of supine blood pressure”. Pending confirmation of its clinical profile in the CYPRESS study, it is anticipated that ampreloxetine will represent a differentiated treatment option for MSA patients with symptomatic nOH.

​

Trelegy (the combination of fluticasone furoate/umeclidinium bromide/vilanterol)

For treatment of COPD, Trelegy competes in all major markets with AstraZeneca’s Breztri^® Aerosphere^® (budesonide/glycopyrronium/formoterol fumarate, dosed twice per day). Trimbow^® (beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide, dosed twice per day) from Chiesi Farmaceutici is an additional COPD competitor in Europe.

​

For treatment of asthma, TRELEGY is the only triple therapy approved in the US and competes in Japan with Novartis’s Enerzair^® Breezhaler^® (indacaterol acetate, glycopyrronium bromide and mometasone furoate, dosed once daily).

​

In both COPD and asthma, TRELEGY also competes with “open triple” therapy which can be accomplished by the concurrent use of two or three products. An example of such use includes a LABA/ICS combination, such as AstraZeneca’s Symbicort^® and a LAMA such as Boehringer Ingelheim’s Spiriva^®.

​

Human Capital

As of December 31, 2023, we had 99 employees. Of these employees, 88 were based in the US, and 11 were based in Dublin, Ireland.

​

Culture and Employee Engagement

We consider our employee relations first-rate and strive to provide a culture of purpose, engagement, and learning. We have a strong value proposition anchored in our Core Values—We Think it Through, We Find a Way, We Get it Done, and We Win Together. We strive to live these values across the Company every day, integrating them into everything from our interview, hiring, and onboarding processes to our PULSE performance process, total rewards, and recognition programs. In addition to valuing professional qualifications, we emphasize the importance of character and integrity, fostering a culture of empowerment where employees have ownership in business outcomes.

​

Reflected in our Core Values are behaviors that keep our people engaged and working collaboratively. Our employees are encouraged to ask questions, make suggestions, and provide input through many forms of corporate communication, such as an open-door policy, all-employee meetings, an anonymous online suggestion box, and an employee PULSE survey. Our employee PULSE survey is designed to assist us in measuring overall employee engagement, and we consistently achieve participation rates between 85% to 100%. Our 2023 survey scores averaged an overall score of 4.5 on a scale of 1 (Strongly Disagree) through 5 (Strongly Agree), and we received 100% participation from employees. These survey results provide important insight into organizational success and allow areas of opportunity to be identified and addressed.

​

We expect all employees to observe the highest levels of business ethics while delivering the highest levels of performance. These expectations are outlined and reinforced in various documents and forms of communication within and across our Company. The Company encourages employees to speak up and raise questions and concerns promptly about any situation that may violate our Code of Business Conduct, our Core Values, or our policies. We seek to promote an environment that fosters honest communications about matters of conduct related to our business activities, whether that conduct occurs within the Company, involves one of the Company’s contractors, suppliers, consultants, clients, or any other party with a business relationship with the Company. We work diligently to make clear that management is prepared to address any reported violations and ensure that it is known that any form of retaliation is strictly prohibited. In addition, we have an easily accessible hotline available to employees wishing to report complaints anonymously.

Diversity, Equity, and Inclusion

As an equal-opportunity employer, we strive to build and maintain a culture of diversity, equity, and inclusion through both our business and human resources practices and policies. We work to eliminate discrimination and harassment in all its forms, including related to color, race, sex or gender, sexual orientation, gender identity, age, pregnancy, caste, disability, ethnicity, national origin, ancestry, religious beliefs, veteran status, uniformed service member status, or physical or mental disability. We strive to build and foster a culture where all employees feel empowered to be their authentic selves. Our Diversity, Equity & Inclusion Council and Women’s Leadership Network are Company-sponsored, employee-led groups that aim to improve attraction, retention, development, inclusion, and engagement of a diverse and global workforce. For the benefit of our employees, patients, and community, we must celebrate, encourage, and support similarities and differences to drive innovation.

​

Talent, Development, and Total Rewards

We believe that our talent strategy of providing exciting career growth and development opportunities, recognizing, and rewarding performance, providing competitive compensation and benefits assists us in attracting and retaining the best talent. We believe we are successful in our retention efforts because we provide challenging work assignments, cross-functional teamwork experiences, and career progression supported by new skill-building. We invest in employee learning and development by identifying and providing training and development programs, speakers, tuition reimbursement, and cross-training in areas of interest beyond hired role.

​

We work diligently to attract the best talent from a diverse range of sources to meet the current and future demands of our business. We offer a competitive total rewards package that supports our business strategy to attract, retain and reward our employees in a highly competitive market. Our employees are provided with a strong base salary, cash bonus opportunities, equity incentives, health and wellness benefits, and programs. We regularly evaluate our compensation programs with an independent consultant and utilize industry benchmarking. In addition, we provide a variety of programs and services that meet our employees' needs and encourage work-life balance. These services include competitive and affordable healthcare and additional insurance benefits for both full-time and part-time employees, including eligible dependents. We also match contributions to tax-qualified defined contribution savings (401k) plans, offer an employee share purchase plan (“ESPP”), and provide training and development programs designed to improve workplace performance while supporting flexible, hybrid-remote working.

​

Understanding the importance of goal setting and ongoing career development conversations, we require managers and employees to play an active role in the PULSE performance management process at monthly, quarterly, and annual frequencies. PULSE is designed to increase clarity and accountability for roles and responsibilities, strengthen communication, and build trust, all while championing personal and professional growth, learning, and success.

​

Workplace Safety

Workplace safety is always a priority for us. To maintain a safe and healthy workplace, we have implemented initiatives, procedures, and policies designed to address risk and stay compliant with relevant national and international health and safety standards. We continue to focus on employee wellness and safety, policy updates based on Centers for Disease Control and Prevention (“CDC”), county, federal, and state guidelines, and ongoing employee communication.

Corporation Information

Theravance Biopharma was incorporated in the Cayman Islands in July 2013 under the name Theravance Biopharma, Inc. Theravance Biopharma began operating as an independent, publicly-traded company on June 2, 2014 following a spin-off from Innoviva, Inc. Our corporate address in the Cayman Islands is P.O. Box 309, Ugland House,

ITEM 1A. RISK FACTORS

The risks described below and elsewhere in this Annual Report on Form 10-K and in our other public filings with the SEC are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

RISKS RELATING TO THE COMPANY

​

We may never achieve or sustain profitability from our operations.

First as part of Innoviva, Inc., and since June 2, 2014 as Theravance Biopharma, we have been engaged in discovery and development of compounds and product candidates since 1997. We may never generate sufficient cash or revenue to achieve sustainable cash flow or profitability from our operations. For the year ended December 31, 2023, we recognized a net loss of $55.2 million. We reflect the cumulative net loss incurred after June 2, 2014, the effective date of our spin-off from Innoviva, Inc. (the “Spin-Off”), as accumulated deficit on our consolidated balance sheets, which was $909.1 million as of December 31, 2023. We may continue to incur net losses over the next several years due to expenditures relating to the development of our current product candidate, which we are advancing into and through

later stage clinical studies without a partner and which we may prepare to commercialize. In addition, we may invest strategically in efforts to continue to support our development and commercial pipeline. While our YUPELRI operations have been profitable on a brand basis since the third quarter of 2020, we will continue to incur costs and expenses associated with the commercialization of YUPELRI in the US, including the maintenance of an independent sales and marketing organization with appropriate technical expertise, a medical affairs presence and consultant support, and post-marketing studies. Our commitment of resources to the continued development of ampreloxetine and YUPELRI will require ongoing funding, and we expect our sales and marketing expenditures to increase in 2024 as we prepare for the potential commercial launch of ampreloxetine. Our operating expenses also will increase if, among other things:

​

​

While we are generating revenues and income from sales of YUPELRI, our economic and royalty interests, and payments under collaboration agreements, we may not generate significant profit from our operations in the near future. We could fail to meet our revenue expectations. If we or our collaborators or licensees are not able to successfully develop additional products, obtain required regulatory approvals, manufacture products at an acceptable cost or with appropriate quality, or successfully market and sell such products, and do so with desired margins, our expenses will continue to exceed any revenues we may receive in the future.

Our strategic business plan is subject to significant uncertainties and risks as a result of, among other factors, the sales levels of our approved product, unplanned expenses, clinical program outcomes, expenses being higher than anticipated, cash receipts being lower than anticipated, whether, when and on what terms we are able to enter into new collaboration arrangements, and the need to satisfy contingent liabilities. Our ability to reach, and the time required to reach, and then to sustain, profitability from operations is uncertain. As a result, we may incur substantial losses in the future. Failure to become and remain profitable from operations would adversely affect the price of our securities and our ability to continue operations as planned.

​

If YUPELRI’s acceptance by physicians, patients, third-party payors, or the medical community in general does not continue to grow, we may not receive significant additional revenues from sales of this product.

The commercial success of YUPELRI depends upon its acceptance by physicians, patients, third-party payors and the medical community in general. YUPELRI’s acceptance by these parties may not continue to grow as we have planned. YUPELRI competes predominately with short acting nebulized bronchodilators that are dosed three to four times per day. If physicians, patients, third-party payors, or the medical community in general believe that YUPELRI is not a preferred treatment option for those with COPD, we may see declines, or fail to grow. If YUPELRI’s acceptance does not continue to grow, or declines from previous levels, our business and financial results could be materially harmed.

In collaboration with Viatris, we are responsible for marketing and sales of YUPELRI in the US, which subjects us to certain risks.

We currently maintain a sales force in the US to support our co-promotion obligations for YUPELRI under our agreement with Viatris. The risks of fulfilling our US co-promotion obligations to Viatris include:

​

​

​

​

If we are not successful in maintaining a sales and marketing organization with appropriate experience, technical expertise, supporting infrastructure and the ability to obtain access to and educate adequate numbers of physicians about prescribing YUPELRI in appropriate clinical situations, we will have difficulty maintaining effective commercialization of YUPELRI in the hospital setting, which would adversely affect our business and financial results, and the condition and the price of our securities could fall.

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

Product candidates must undergo extensive non-clinical and clinical studies as a condition to regulatory approval. Clinical studies are expensive, take many years to complete and study results may lead to delays in further studies, new requirements for conducting future studies or decisions to terminate programs. The completion of clinical studies for our product candidate may be delayed and programs may be terminated due to many factors, including, but not limited to:

​

​

​

Any adverse developments or results or perceived adverse developments or results with respect to our clinical program including, without limitation, any delays in development in our program, any halting of development in our program, any difficulties or delays encountered with regard to the FDA or other third country regulatory authorities with respect to our program, or any indication from clinical or non-clinical studies that the compounds in our program are not safe, efficacious or sufficiently differentiated from those of our competitors, could have a material adverse effect on our business and cause the price of our securities to fall. For example, in August 2021 we announced that our Phase 2b study of izencitinib in ulcerative colitis did not meet its primary endpoint, and in September 2021, we announced that our four-week SEQUOIA Phase 3 study for ampreloxetine did not meet its primary endpoint. There can be no assurance that our Phase 3 study for ampreloxetine will be completed on the timeline we expect or at all, that the CYPRESS study will meet its endpoints, or that ampreloxetine will ultimately be found to be safe and effective.

If our product candidates are not approved by regulatory authorities, including the FDA, we will be unable to commercialize them.

The FDA must approve any new medicine before it can be marketed and sold in the US. We will not obtain this approval for a product candidate, such as ampreloxetine, unless and until the FDA approves an NDA. We, or our collaborative partners, must provide the FDA and similar foreign regulatory authorities with data from preclinical and clinical studies that demonstrate that our product candidates comply with the regulatory requirements for the quality of medicinal products and are safe and effective for a defined indication before they can be approved for commercial distribution. FDA or foreign regulatory authorities may disagree with our trial design and our interpretation of data from preclinical studies and clinical trials. The processes by which regulatory approvals are obtained from the FDA and foreign regulatory authorities to market and sell a new product are complex, require a number of years, depend upon the type, complexity and novelty of the product candidate and involve the expenditure of substantial resources for research, development and testing. The FDA has substantial discretion in the drug approval process and may require us to conduct additional non-clinical and clinical testing or to perform post-marketing studies. Further, the implementation of new laws and regulations, and revisions to FDA clinical trial design guidance may lead to increased uncertainty regarding the approvability of new drugs. See the risk factor entitled “Any delay in commencing or completing clinical studies for product candidates or product and any adverse results from clinical or non-clinical studies or regulatory obstacles product candidates or product may face, would harm our business and the price of our securities could fall” above for additional information. In addition, the FDA has additional standards for approval of new drugs, including recommended advisory committee meetings for certain new molecular entities, and formal risk evaluation and mitigation requirements at the FDA’s discretion. Even if we receive regulatory approval of a product, the approval may limit the indicated uses for which the drug may be marketed or impose significant restrictions or limitations on the use and/or distribution of such product.

In addition, in order to market our medicines in foreign jurisdictions, we or our collaborative partners must obtain separate regulatory approvals in each country. The approval procedure varies among countries and can involve additional testing, and the time required to obtain approval may differ from that required to obtain FDA approval. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or by the FDA. Conversely, failure to obtain approval in one or more jurisdictions may make approval in other jurisdictions more difficult. These laws, regulations, additional requirements and changes in interpretation could cause non-approval or further delays in the FDA’s or other regulatory authorities’ review and approval of our and our collaborative partners’

23

product candidates, which would materially harm our business and financial condition and could cause the price of our securities to fall.

If our partners do not satisfy their obligations under our agreements with them, or if they terminate our partnerships with us, we may not be able to develop or commercialize our partnered product candidates as planned.

In January 2015, we entered into a collaboration agreement with Viatris for the development and commercialization of a nebulized formulation of our LAMA revefenacin, including YUPELRI. Under the terms of the agreement, we and Viatris will co-develop nebulized revefenacin, including YUPELRI, for COPD and other respiratory diseases. In 2019, we granted Viatris exclusive development and commercialization rights to nebulized revefenacin in China and adjacent territories, which include the Hong Kong SAR, the Macau SAR, and Taiwan, and we are eligible to receive low double-digit tiered royalties on net sales of nebulized revefenacin, if approved. Viatris is responsible for all aspects of development and commercialization of nebulized revefenacin in China and adjacent territories, including pre- and post-launch activities and product registration and all associated costs. In connection with these agreements, Viatris has certain rights regarding the use of patents and technology with respect to the compounds in our development programs, including development and marketing rights.

Our partner may not fulfill their obligations under our agreements, and, in certain circumstances, they or we may terminate our partnership with them. For example, in June 2023, we received notice from Pfizer terminating the License Agreement (the “Pfizer Agreement”) with Pfizer Inc. (“Pfizer”) regarding our preclinical program for skin targeted, locally acting pan Janus kinase (JAK) inhibitors that can be rapidly metabolized as of October 2023. We are assessing our choices with respect to the program covered by the Pfizer Agreement. We may be unable to assume the development and commercialization responsibilities covered by the agreements or enter into alternative arrangements with a third-party to develop and commercialize such product candidates. If a partner elected to promote alternative products and product candidates such as its own products and product candidates in preference to those licensed from us, does not devote an adequate amount of time and resources to our product or product candidates or is otherwise unsuccessful in its efforts with respect to our products or product candidates, the development and commercialization of products and product candidates covered by the agreements could be delayed or terminated, and future payments to us could be delayed, reduced or eliminated and our business and financial condition could be materially and adversely affected. Accordingly, our ability to receive any revenue from the products and product candidates covered by these agreements is dependent on the efforts of our partners. If a partner terminates or breaches its agreements with us, otherwise fails to complete its obligations in a timely manner or alleges that we have breached our contractual obligations under these agreements, the chances of successfully developing or commercializing products and product candidates under the collaboration could be materially and adversely affected. In addition, effective collaboration with a partner requires coordination to achieve complex and detail-intensive goals between entities that potentially have different priorities, capabilities and processes and successful navigation of the challenges such coordination entails. We could also become involved in disputes with a partner, which could lead to delays in or termination of our development and commercialization programs and time-consuming and expensive litigation or arbitration. Furthermore, termination of an agreement by a partner could have an adverse effect on the price of our ordinary shares or other securities even if not material to our business.

Our ongoing drug development efforts might not generate additional approvable drugs.

Our compounds in clinical trials are subject to the risks and failures inherent in the development of pharmaceutical products. These risks include, but are not limited to, the inherent difficulty in selecting the right drug and drug target and avoiding unwanted side effects, as well as unanticipated problems relating to product development, testing, enrollment, obtaining regulatory approvals, maintaining regulatory compliance, manufacturing, competition and costs and expenses that may exceed current estimates.

Clinical studies involving our product candidates may reveal that those candidates are ineffective, inferior to existing approved medicines, unacceptably toxic, or that they have other unacceptable side effects. In addition, the results of preclinical studies do not necessarily predict clinical success, and larger and later-stage clinical studies may not produce the same results as earlier-stage clinical studies. For example, despite promising early stage studies, we previously announced that two late stage clinical programs failed to meet their primary endpoints. There can be no assurance that our Phase 3 study for ampreloxetine will meet its primary endpoint, and developments and results from that study may be adverse or may be perceived to be adverse.

Table of Contents

Frequently, product candidates that have shown promising results in early preclinical or clinical studies have subsequently suffered significant setbacks or failed in later non-clinical or clinical studies. In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, varying levels of adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. Clinical and non-clinical studies of product candidates often reveal that it is not possible or practical to continue development efforts for these product candidates. In addition, the design of a clinical trial can determine whether its results will support regulatory approval and flaws in the design of a clinical trial may not become apparent until the clinical trial is well underway or completed. As our clinical studies for one of our prior product candidates suggested that our product candidate was not efficacious in the indications we were investigating, we choose to cease development of this product candidate. In addition, our product candidates may have undesirable side effects or other unexpected characteristics that could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restricted label or the delay or denial of regulatory approval by regulatory authorities.

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

Our ability to succeed in the future depends on our ability to demonstrate and maintain a competitive advantage with respect to our approach to the discovery, development and commercialization of medicines. Our objective is to develop and commercialize new small molecule medicines with superior efficacy, convenience, tolerability and/or safety. We expect that any medicines that we commercialize with or without our collaborative partners will compete with existing or future market-leading medicines.

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

​

​

​

​

​

​

Pharmaceutical companies, including companies with which we collaborate, may invest heavily to quickly discover and develop or in-license novel compounds that could make our product or product candidate obsolete. Accordingly, other companies may succeed in obtaining patent protection, conducting clinical trials, receiving FDA or equivalent regulatory approval outside the US or discovering, developing and commercializing medicines before we do. Other companies are engaged in the discovery of medicines that would compete with the product candidate that we are developing or our existing product.

Any new medicine that competes with a generic or proprietary market leading medicine must demonstrate compelling advantages in efficacy, convenience, tolerability and/or safety in order to overcome severe price competition and be commercially successful. For example, YUPELRI competes predominately with short acting nebulized bronchodilators that are dosed three to four times per day, Verona Pharma plc’s ensifentrine, a first-in-class, selective inhaled dual inhibitor of PDE3 and PDE4 is expected to launch in the US in the second half of 2024, and Sanofi and

Regeneron Pharmaceutical, Inc. are expecting US approval for their first-in-class, IL-4/IL-13 monoclonal antibody (mAb) Dupixent^® (dupilumab) for COPD in the second half of 2024 for the maintenance treatment for patients with moderate-to-severe COPD, who are uncontrolled with current SOC triple therapy (LAMA + LABA + ICS) and have evidence of Type 2 inflammation and frequent exacerbation history. If successfully developed and approved, ampreloxetine would be expected to serve as the only safe, convenient, and durably effective treatment option for MSA patients with symptomatic nOH, entering a market where generic droxidopa is currently the sole product approved for nOH patients and midodrine is approved for OH. If we are not able to compete effectively against our current and future competitors, our business will not grow, our financial condition and operations will suffer and the price of our securities could fall.

There is a single source of supply for our product candidates and for YUPELRI, and our business will be harmed if any of these single-source manufacturers are not able to satisfy demand and alternative sources are not available.

We depend on a number of third-party Active Pharmaceutical Ingredient (“API”) and drug product manufacturers for clinical study purposes and we depend on third party suppliers for warehousing and storage of our existing API and drug product. We may not have long-term agreements with these third parties and our agreements with these parties may be terminable at will by either party at any time. In addition, there is a single supplier of YUPELRI API, a single supplier of YUPELRI drug product and YUPELRI is warehoused in a single facility. If, for any reason, any of these third-party manufacturers are unable or unwilling to perform, or if their performance does not meet regulatory requirements, alternative manufacturers may not be available or may not be available on acceptable terms. For example, while we have not been directly or indirectly materially impacted, manufacturers and warehousing suppliers are periodically impacted by natural disasters, accidents, labor disputes, labor shortages, regulatory actions, public healthy emergencies and geopolitical factors. Any inability to acquire sufficient quantities of API and drug product in a timely manner from these third parties could delay clinical studies or prevent us from developing our product candidates in a cost-effective manner or on a timely basis or adversely impact YUPELRI sales. In addition, manufacturers of our API and drug product are subject to the FDA’s current Good Manufacturing Practice (“cGMP”) regulations and similar foreign standards and we do not have control over compliance with these regulations by our manufacturers.

​

Our manufacturing strategy presents the following additional risks:

​

​

​

​

We are subject to extensive and ongoing regulation, oversight and other requirements by the FDA and failure to comply with these regulations and requirements may subject us to penalties that may adversely affect our financial condition or our ability to commercialize any approved products.

Prescription drug advertising and promotion are closely scrutinized by the FDA, including substantiation of promotional claims, disclosure of risks and safety information, and the use of themes and imagery in advertising and promotional materials. As with all companies selling and marketing products regulated by the FDA in the US, we are prohibited from promoting any uses of an approved product, such as YUPELRI, that are outside the scope of those uses that have been expressly approved by the FDA as safe and effective on the product’s label.

26

Table of Contents

The manufacturing, labeling, packaging, adverse event reporting, advertising, promotion, and recordkeeping for an approved product remain subject to extensive and ongoing regulatory requirements. If we become aware of previously unknown problems with an approved product in the US or overseas or at a contract manufacturer’s facilities, a regulatory authority may impose restrictions on the product, the contract manufacturers or on us, including requiring us to reformulate the product, conduct additional clinical studies, change the labeling of the product, withdraw the product from the market or require the contract manufacturer to implement changes to its facilities.

We are also subject to regulation by regional, national, state, and local agencies, including the Department of Justice, the Federal Trade Commission, the Office of Inspector General of the US Department of Health and Human Services (“OIG”) and other regulatory bodies with respect to any approved product, such as YUPELRI, as well as governmental authorities in those foreign countries in which any product is approved for commercialization. The Federal Food, Drug, and Cosmetic Act, the Public Health Service Act and other federal and state statutes and regulations govern to varying degrees the research, development, manufacturing, and commercial activities relating to prescription pharmaceutical products, including non-clinical and clinical testing, approval, production, labeling, sale, distribution, import, export, post-market surveillance, advertising, dissemination of information and promotion. If we or any third parties that provide these services for us are unable to comply, we may be subject to regulatory or civil actions or penalties that could significantly and adversely affect our business.

Regulatory approval for our product candidates, if any, may include similar or other limitations on the indicated uses for which we can market our medicines or the patient population that may utilize our medicines, which may limit the market for our medicines or put us at a competitive disadvantage relative to alternative therapies.

Failure to satisfy required post-approval requirements and/or commitments may have implications for a product’s approval and may carry civil monetary penalties. Any failure to maintain regulatory approval will materially limit the ability to commercialize a product or any future product candidates and if we fail to comply with FDA regulations and requirements, the FDA could potentially take a number of enforcement actions against us, including the issuance of untitled letters, warning letters, preventing the introduction or delivery of the product into interstate commerce in the US, misbranding charges, product seizures, injunctions, and civil monetary penalties, which would materially and adversely affect our business and financial condition and may cause the price of our securities to fall.

The risks identified in this risk factor relating to regulatory actions and oversight by agencies in the US and throughout the world also apply to the commercialization of any partnered products by our collaboration partners and those commercializing products with respect to which we have an economic interest or right to receive royalties, including GSK, and such regulatory actions and oversight may limit those parties’ ability to commercialize such products, which could materially and adversely affect our business and financial condition, and which may cause the price of our securities to fall.

We and/or our collaboration partners and those commercializing products with respect to which we have an economic interest or right to receive royalties may face competition from companies seeking to market generic versions of any approved products in which we have an interest, such as YUPELRI.

Under the Drug Price Competition and Patent Term Restoration Act of 1984, a company may submit an abbreviated new drug application (“ANDA”) under section 505(j) of the Federal Food, Drug, and Cosmetic Act to market a generic version of an approved drug. Because a generic applicant does not conduct its own clinical studies, but instead relies on the FDA’s finding of safety and effectiveness for the approved drug, it is able to introduce a competing product into the market at a cost significantly below that of the original drug. Although we have multiple patents protecting YUPELRI with expiration dates ranging from 2025 to 2039 that are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, generic applicants have submitted, and could potentially submit additional, “paragraph IV certifications” to FDA stating that such patents are invalid or will not be infringed by the applicant’s product. In fact, on January 10, 2023, the FDA included seven ANDAs that referred to YUPELRI (revefenacin) inhalation solution and contained a paragraph IV certification on its Paragraph IV Certifications List. As of February 28, 2024, we have settled litigation with some of the generic applicants, and pursuant to individual agreements, we granted these companies a royalty-free, non-exclusive, non-sublicensable, non-transferable license to manufacture and market their respective generic versions of YUPELRI inhalation solution in the US on or after the licensed launch date of April 23, 2039, subject to certain exceptions as is customary in these type of

27

Table of Contents

agreements. We are not aware of any other paragraph IV notifications with respect to products in which we have an economic interest or right to receive royalties. Our collaboration partner, Viatris, is responsible for enforcing our Orange Book patents relating to YUPELRI, in consultation with us, and our views may differ from theirs with respect to the ongoing litigation, process or strategy and we have a reduced ability to control the outcome of the litigation. If any competitors successfully challenge the patents related to these products, including YUPELRI, we and/or our collaboration partners and those commercializing products with respect to which we have an economic interest or right to receive royalties would face substantial competition. If we are not able to compete effectively against such future competition, our business will not grow, our financial condition and operations will suffer and the price of our securities could fall.

For additional discussion of the risk of generic competition to YUPELRI, please see the risk factor below entitled “If our efforts to protect the proprietary nature of the intellectual property related to our technologies are not adequate, we may not be able to compete effectively in our current or future markets” and “Litigation to protect or defend our intellectual property or third party claims of intellectual property infringement will require us to divert resources and may prevent or delay our drug discovery and development efforts.”

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

We have a collaboration with Viatris for the development and commercialization of a nebulized formulation of revefenacin, which is a LAMA compound (including YUPELRI). In addition, we plan to seek a partnership to continue progression of our inhaled JAK inhibitor program. Additional collaborations, if any, may be needed to progress additional programs and to commercialize the product candidates in our programs if approved by the necessary regulatory authorities. We evaluate commercial strategy on a product by product basis either to engage pharmaceutical or other healthcare companies with an existing sales and marketing organization and distribution system to market, sell and distribute our products or to commercialize a product ourselves. However, we may not be able to establish these sales and distribution relationships on acceptable terms, or at all, or may encounter difficulties in commercializing a product ourselves. For any of our product candidates that receive regulatory approval in the future and are not covered by our current collaboration agreements, we will need a partner in order to commercialize such products unless we establish independent sales, marketing and distribution capabilities with appropriate technical expertise and supporting infrastructure.

Collaborations with third parties regarding our programs may require us to relinquish material rights, including revenue from commercialization of our medicines, or to assume material ongoing development obligations that we would have to fund. These collaboration arrangements are complex and time-consuming to negotiate, and if we are unable to reach agreements with third-party collaborators, we may fail to meet our business objectives and our financial condition may be adversely affected. We face significant competition in seeking third-party collaborators. We may be unable to find third parties to pursue product collaborations on a timely basis or on acceptable terms.

Furthermore, once we enter into a collaboration, our collaboration partners are frequently important for the success of the product or product candidate. For example, Viatris’ role in the commercialization of YUPELRI is important to the overall success of product. In addition, since we do not currently intend to progress our skin-selective pan-JAK inhibitor program internally, Pfizer was important to such program’s development. However, for any collaboration, we may not be able to control the amount of time and resources that our partners devote to our products or product candidates and our partners may choose to prioritize alternative programs or otherwise be unsuccessful in their efforts with respect to our products or product candidates. In addition, effective collaboration with a partner requires coordination to achieve complex and detail-intensive goals between entities that potentially have different priorities, capabilities and processes and successful navigation of the challenges such coordination entails. For example, Viatris has a substantial existing product portfolio largely comprising generic products, other considerations and incentives that influence its resource allocation, and background, experiences, priorities, and internal organizational processes that differ from our own. As a result of these differing backgrounds, interests, and processes, Viatris 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 shareholders. Our inability to successfully collaborate with third parties would increase our development costs and may cause us to choose not to continue development of certain product candidates, would limit the likelihood of successful commercialization of

28

Table of Contents

some of our product candidates, may cause us not to continue commercialization of our authorized products and could cause the price of our securities to fall.

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

We depend on independent clinical investigators, contract research and manufacturing organizations and other third-party service providers in the conduct of our non-clinical and clinical studies for our product candidates. We rely heavily on these parties for execution of our non-clinical and clinical studies, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that our clinical studies are conducted in accordance with good clinical, laboratory and manufacturing practices (“GXPs”) and other regulations as required by the FDA and foreign regulatory authorities, and the applicable protocol. Failure by these parties to comply with applicable regulations and practices in conducting studies of our product candidates can result in a delay in our development programs or non-approval of our product candidates by regulatory authorities.

The FDA, and equivalent authorities in third countries, enforces GXPs and other regulations through periodic inspections of trial sponsors, clinical research organizations (“CROs”), principal investigators and trial sites. If we or any of the third parties on which we have relied to conduct our clinical studies are determined to have failed to comply with GXPs (or other equivalent regulations outside the US), the study protocol or applicable regulations, the clinical data generated in our studies may be deemed unreliable. This could result in non-approval of our product candidates by the FDA, or equivalent authorities in other countries, or we, the FDA, or equivalent authorities in other countries may decide to conduct additional audits or require additional clinical studies, which would delay our development programs, could result in significant additional costs and cause the price of our securities to fall.

If there are any adverse developments or perceived adverse developments with respect to TRELEGY, we may not receive Milestone Payments or the revenue we expect from the Outer Years Royalty, which would harm our business and could cause the price of our securities to fall.

Through the milestone payments we may receive from Royalty Pharma if certain TRELEGY global net sales thresholds are met following our sale of our economic interest in TRELEGY (the “Milestone Payments”) and pursuant to our right to receive from Royalty Pharma 85% of the royalty payments on the Assigned Collaboration Products (as defined in the Purchase Agreement) payable (a) for sales or other activities occurring on and after January 1, 2031 related to the Assigned Collaboration Products in the US, and (b) for sales or other activities occurring on and after July 1, 2029 related to the Assigned Collaboration Products outside of the US (the “Outer Years Royalty” and, together with the Milestone Payments, the “Ongoing Economic Interest”), we may participate in the mid- and long-term economically in royalty payments from GSK with respect to the TRELEGY. However, we cannot assure you as to the amount, if any, we might receive. We have no access to non-public information regarding the development progress of, or plans for TRELEGY, and we have no current authority to enforce rights under the GSK Agreements assigned to TRC. However, if there are any adverse developments or perceived adverse developments with respect to TRELEGY, we may not realize the value we currently anticipate from the Ongoing Economic Interest, which would harm our business and may cause the price of our securities to fall. Examples of such adverse developments include, but are not limited to:

​

​

We do not control the commercialization of TRELEGY; accordingly, our receipt of Milestone Payments and receipt of the value we currently anticipate from the Outer Years Royalty will depend on, among other factors, GSK’s ability to further commercialize TRELEGY.

Our Ongoing Economic Interest in TRELEGY consists of the potential Milestone Payments and our right to receive from Royalty Pharma the Outer Years Royalty, both of which are ultimately based on the amount of sales of this product by GSK. Any benefit we may receive from the Ongoing Economic Interest will depend on GSK’s ability to commercialize the product, and the future payments, if any, made by GSK to Royalty Pharma.

Accordingly, our Ongoing Economic Interest involves a number of risks and uncertainties, including:

These risks and uncertainties could materially impact the amount and timing of future Milestone Payments and Outer Years Royalty, which could have a material adverse effect on our future revenues, other financial results and our financial position and cause the price of our securities to fall.

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

We are highly dependent on principal members of our management team and commercial and scientific staff, and in particular, our Chief Executive Officer, Rick E Winningham, to operate our business. Mr. Winningham has significant pharmaceutical industry experience. The loss of Mr. Winningham’s services could impair our ability to discover, develop and commercialize new medicines.

If we fail to retain our qualified personnel or replace them when they leave, we may be unable to continue our development and commercialization activities, which may cause the price of our securities to fall. The Restructuring announced in September 2021, and completed in the third quarter of 2022, and the additional headcount reductions announced in February 2023, may make retention of our current personnel both more important and more challenging.

In addition, our US operating subsidiary’s facility and most of its employees are located in northern California, 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 is intense. None of our employees have employment commitments for any fixed period of time and they all may leave our employment at will. If we fail to retain our qualified personnel or replace them when they leave, we may be unable to continue our development and commercialization activities and the price of our securities could fall.

Our business and operations would suffer in the event of significant disruptions of information technology systems or security breaches.

We rely extensively on computer systems to maintain information and manage our finances and business. In the ordinary course of business, we collect, store, and transmit large amounts of confidential information (including but not limited to trade secrets or other intellectual property, proprietary business information and personal information) and it is critical that we maintain the confidentiality and integrity of such confidential information. Although we have security measures in place, our internal information technology systems and those of our CROs and other service providers, including cloud based and hosted applications, data and services, may be vulnerable to service interruptions and security breaches from inadvertent or intentional actions by our employees, service providers and/or business partners, from cyber-attacks by malicious third parties, including but not limited to those involving malware and ransomware, which can disrupt operations significantly, and/or from, natural disasters, terrorism, war and telecommunication and electrical failures. Cyber-attacks are increasing in their frequency, sophistication, and intensity, and have become increasingly difficult to detect. Significant disruptions of information technology systems or security breaches could adversely affect our business operations and result in financial, legal, business, and reputational harm to us, including significant liability and/or significant disruption to our business. If a disruption of information technology systems or security breach results in a loss of or damage to our data or regulatory applications, unauthorized access, use, or disclosure of, or the prevention of access to, confidential information, or other harm to our business, we could incur liability and reputational harm, we could be required to comply with federal and/or state breach notification laws and foreign law equivalents, we may incur legal expenses to protect our confidential information, the further development of our product candidates could be delayed and the price of our securities could fall. For example, the loss of clinical trial data from completed or ongoing clinical trials of our product candidates could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. As another example, we may incur penalties imposed by the competent authorities in the EU Member States in case of breach of the EU rules governing the collection and processing of personal data, including unauthorized access to or disclosure of personal data. In addition, we may suffer damages as a result of civil (class action) claims in response to security breaches. Although we have security and fraud prevention measures in place, we have been subject to immaterial payment fraud activity. In 2017, we filed a lawsuit (which has since been resolved) against a former employee for misappropriation of our confidential, proprietary and trade secret information. Moreover, there can be no assurance that our security measures will prevent service interruptions or security breaches that could adversely affect our business. These same risks also apply to our partners and vendors, who similarly hold sensitive and critical information related to our business in computer systems and are similarly potentially vulnerable to service interruptions and security breaches.

We face risks related to widespread illnesses, including the recent COVID-19 pandemic, which could have a material adverse effect on our business and results of operations.

Our business has been and may continue to be adversely affected by the outbreak of respiratory illness caused by a novel strain of coronavirus, SARS-CoV-2, causing the Coronavirus Disease 2019, also known as COVID-19 (the “COVID-19 pandemic”).

Sales momentum was affected by COVID-19 in the past and may continue to be in the future. We market YUPELRI in the hospital setting and to pulmonologists, whose practices were, and may be in the future, impacted by the pandemic or future respiratory pandemics. Customer orders or new patient use of YUPELRI may decline or fail to grow as a result of, among other things, a shift in our marketing efforts, increased workload of healthcare providers, staffing challenges at hospitals, and the impact of any concerns regarding nebulization in COVID-19 positive patients.

Challenges to the conduct of clinical trials may continue to arise due to the COVID-19 pandemic from site closures, site staffing shortages, potential interruptions to the supply chain for investigational products, or other considerations if site personnel or trial participants become infected with COVID-19. These challenges may lead to difficulties in meeting protocol-specified procedures.

If significant portions of our workforce, and particularly our field-based teams, are unable to work effectively, including due to illness, quarantines, social distancing, government actions or other restrictions in connection with the COVID-19 pandemic or other health emergencies, our operations will be impacted. The COVID-19 pandemic or other health emergencies could limit the ability of our customers, suppliers, and business partners to perform under their

31

Table of Contents

contracts with us, including third-party payers’ ability to make timely payments to us during and following the pandemic. Even now that the COVID-19 pandemic has largely subsided, we may continue to experience an adverse impact to our business as a result of its global economic impacts.

Global economic, political, and social conditions may harm our ability to do business, increase our costs and negatively affect our stock price.

Worldwide economic conditions remain uncertain due to current global economic challenges, hostilities in Ukraine and the Middle East, the COVID-19 pandemic and other health emergencies, the United Kingdom’s (“UK”) withdrawal from the EU (often referred to as “Brexit”), inflation, instability in the US banking sector and other disruptions to global and regional economies and markets.

Further, development of our product candidates and/or regulatory approval may be delayed for other political events beyond our control. For example, a US federal government shutdown or budget sequestration, such as ones that occurred during 2013, 2018, and 2019, may result in significant reductions to the FDA’s budget, employees, and operations, which may lead to slower response times and longer review periods, potentially affecting our ability to progress development of our product candidates or obtain regulatory approval for our product candidates. Further, future government shutdowns, including as a result of the US failing to raise the debt ceiling, could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Our operations also depend upon favorable trade relations between the US and those foreign countries, including China, in which our materials suppliers have operations. A protectionist trade environment in either the US or those foreign countries in which we do business, such as a change in the current tariff structures, export compliance or other trade policies, may materially and adversely affect our operations.

Brexit created significant uncertainty about the future relationship between the UK and the EU, including with respect to the laws and regulations that will apply as the UK determines which EU laws to replace or replicate after withdrawal. From a regulatory perspective, the UK’s withdrawal bears significant complexity and risks.

External factors, such as potential terrorist attacks, acts of war, geopolitical and social turmoil, including the ongoing hostilities between Russia and Ukraine, similar events in many parts of the world or the worsening of such factors, could also prevent or hinder our ability to do business, increase our costs and negatively affect our stock price. These geopolitical, social, and economic conditions could harm our business.

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

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

If sufficient capital is not available, we may have to further curtail operations or we could be forced to share our rights to commercialize our product candidates with third parties on terms that may not be favorable to us.

Based on our current operating plans and financial forecasts, we believe that our existing cash, cash equivalents and marketable securities will be sufficient to meet our anticipated operating needs for at least the next twelve months. However, our current operating plans or financial forecasts occasionally change. For example, in August 2017, we announced an increase in our anticipated operating loss for 2017, primarily driven by our decision to accelerate funding associated with the next phase of development of izencitinib in our JAK inhibitor program. In addition, following

unfavorable results from our late-stage development programs, in September 2021, we announced a strategic update and corporate restructuring (the “2021 Restructuring”), including a reduction in headcount by approximately 75% through a reduction in our workforce of regular and contingent workers. The 2021 Restructuring was completed during the third quarter of 2022, and we announced additional headcount reductions in February 2023. If our current operating plans or financial forecasts change, we may require or seek additional funding in the form of public or private equity or equity-linked offerings, debt financings or additional collaborations and licensing arrangements. In addition, as of December 31, 2023, we had cash, cash equivalents and marketable securities of $102.4 million, which do not reflect our repurchase of $0.4 million of our ordinary shares during January 2024 under our share repurchase program.

​

Our future capital needs depend on many factors, including:

​

​

​

​

​

​

​

​

​

If we require additional funding, we may not be able to obtain additional financing on terms favorable to us, if at all. General market conditions may make it difficult for us to seek financing from the capital markets. We may be required to relinquish rights to our technologies, product candidates or territories, or grant licenses on terms that are not favorable to us, in order to raise additional funds through collaborations or licensing arrangements. We may also have to sequence studies as opposed to conducting them concomitantly in order to conserve resources, or, as we announced in September 2021 and in February 2023, we may need to delay, reduce, or eliminate one or more of our programs and reduce overall overhead expenses. In addition, we may have to make additional reductions in our workforce and may be prevented from continuing our development and commercialization efforts and exploiting other corporate opportunities. This would likely harm our business, prospects and financial condition, and cause the price of our securities to fall.

We may seek to obtain future financing through the issuance of debt or equity, which may have an adverse effect on our shareholders or may otherwise adversely affect our business.

We may in the future need to raise additional funds to continue to progress our business. If we raise funds through the issuance of additional debt, including convertible debt or debt secured by some or all of our assets, or equity, any debt securities or preferred shares issued will have rights, preferences, and privileges senior to those of holders of our ordinary shares in the event of liquidation. We do not have any outstanding long-term debt, but if additional debt is issued or we otherwise borrow additional funds in the future, there is a possibility that once all senior claims are settled, there may be no assets remaining to pay out to the holders of ordinary shares. In addition, if we raise funds through the

33

Table of Contents

issuance of additional equity, whether through private placements or public offerings, such an issuance would dilute ownership of our current shareholders that do not participate in the issuance. If we are unable to obtain any needed additional funding, we may be required to reduce the scope of, delay, or eliminate some or all of, our planned development and commercialization activities or to license to third parties the rights to develop and/or commercialize products or technologies that we would otherwise seek to develop and/or commercialize ourselves or on terms that are less attractive than they might otherwise be, any of which could materially harm our business.

Furthermore, the terms of any debt securities we may issue in the future may impose restrictions on our operations, which may include limiting our ability to incur additional indebtedness, pay dividends on or repurchase our share capital, or make certain acquisitions or investments. In addition, we may be subject to covenants requiring us to satisfy certain financial tests and ratios, and our ability to satisfy such covenants may be affected by events outside of our control.

We may be treated as a US corporation for US federal income tax purposes.

For US federal income tax purposes, a corporation generally is considered tax resident in the place of its incorporation. Theravance Biopharma is incorporated under Cayman Islands law and established tax residency in Ireland effective July 1, 2015. Therefore, it should be a non-US corporation under this general rule. However, Section 7874 of the Internal Revenue Code of 1986, as amended (the “Code”), contains rules that may result in a foreign corporation being treated as a US corporation for US federal income tax purposes. The application of these rules is complex and there is little guidance regarding certain aspects of their application.

Under Section 7874 of the Code, a corporation created or organized outside the US will be treated as a US corporation for US federal tax purposes if (i) the foreign corporation directly or indirectly acquires substantially all of the properties held directly or indirectly by a US corporation, (ii) the former shareholders of the acquired US corporation hold at least 80% of the vote or value of the shares of the foreign acquiring corporation by reason of holding stock in the US acquired corporation, and (iii) the foreign corporation’s “expanded affiliated group” does not have “substantial business activities” in the foreign corporation’s country of incorporation relative to its expanded affiliated group’s worldwide activities. For this purpose, “expanded affiliated group” generally means the foreign corporation and all subsidiaries in which the foreign corporation, directly or indirectly, owns more than 50% of the stock by vote and value, and “substantial business activities” generally means at least 25% of employees (by number and compensation), assets and gross income of our expanded affiliated group are based, located, and derived, respectively, in the country of incorporation.

We do not expect to be treated as a US corporation under Section 7874 of the Code, because we do not believe that the assets contributed to us by Innoviva constituted “substantially all” of the properties of Innoviva (as determined on both a gross and net fair market value basis). However, the Internal Revenue Service may disagree with our conclusion on this point and assert that, in its view, the assets contributed to us by Innoviva did constitute “substantially all” of the properties of Innoviva. In addition, there could be legislative proposals to expand the scope of US corporate tax residence and there could be changes to Section 7874 of the Code or the Treasury Regulations promulgated thereunder that could apply retroactively and could result in Theravance Biopharma being treated as a US corporation.

If it were determined that we should be treated as a US corporation for US federal income tax purposes, we could be liable for substantial additional US federal income tax on our post-Spin-Off taxable income. In addition, though we have no current plans to pay any dividends, payments of any dividends to non-US holders may be subject to US withholding tax.

Future tax reform, including changes in tax rates and imposition of new taxes, could impact our results of operations and financial condition.

We are incorporated in the Cayman Islands, maintain subsidiaries in the Cayman Islands (until December 2020), the US, the UK and Ireland, and effective July 1, 2015, we migrated our tax residency from the Cayman Islands to Ireland. We are subject to new, evolving, or revised tax laws and regulations in such jurisdictions, and the enactment of or increases in taxes, or other changes in the application of existing taxes, in such jurisdictions may have an adverse effect on our business or on our results of operations. Due to economic and political conditions, tax rates in various jurisdictions may be subject to significant change. Our future effective tax rate could be affected by changes in our mix

34

Table of Contents

of earnings in countries with differing statutory tax rates, changes in valuation of our deferred tax assets and liabilities, or changes in tax laws or their interpretation, including possible US tax reform and contemplated changes in other countries of long-standing tax principles. These and other similar changes, if finalized and adopted, could have a material impact on our income tax expense and deferred tax balances.

Taxing authorities may challenge our structure and transfer pricing arrangements.

We are incorporated in the Cayman Islands, maintain subsidiaries in the Cayman Islands (until December 2020), the US, the UK and Ireland, and effective July 1, 2015, we migrated our tax residency from the Cayman Islands to Ireland. Due to economic and political conditions, various countries are actively considering changes to existing tax laws. We cannot predict the form or timing of potential legislative changes that could have a material adverse impact on our results of operations. Ireland has implemented further tax law changes through the Finance Act 2021 to comply with the European Union Anti-Tax Avoidance Directives. Changes to date, including reverse-hybrid mismatch and interest limitation rules, are not expected to have a material impact on the Company’s tax position.

In April 2020, we became aware of a withholding tax regulation that could be interpreted to apply to certain of our previous intra-group transactions. Additional draft guidance on this withholding tax regime was released in late 2020 and early 2021, and based on our analysis of this guidance, we do not believe the exposure to be material. We continue to monitor the evolving legislation relating to this matter and will consider its impact on our consolidated financial statements.

In addition, significant judgment is required in determining our worldwide provision for income taxes. Various factors may have favorable or unfavorable effects on our income tax rate including, but not limited to the performance of certain functions and ownership of certain assets in tax-efficient jurisdictions such as the Cayman Islands and Ireland, together with intra-group transfer pricing agreements. Taxing authorities may challenge our structure and transfer pricing arrangements through an audit or lawsuit. Responding to or defending such a challenge could be expensive and consume time and other resources, and divert management’s time and focus from operating our business. We cannot predict whether taxing authorities will conduct an audit or file a lawsuit challenging this structure, the cost involved in responding to any such audit or lawsuit, or the outcome. We may be required to pay taxes for prior periods, interest, fines or penalties, and may be obligated to pay increased taxes in the future which could result in reduced cash flows and have a material adverse effect on our business, financial condition and growth prospects.

We were a passive foreign investment company, or “PFIC,” for 2014, but we were not a PFIC from 2015 through 2023, and we do not expect to be a PFIC for the foreseeable future.

For US federal income tax purposes, we generally would be classified as a PFIC for any taxable year if either (i) 75% or more of our gross income (including gross income of certain 25% or more owned corporate subsidiaries) is “passive income” (as defined for such purposes) or (ii) the average percentage of our assets (including the assets of certain 25% or more owned corporate subsidiaries) that produce passive income or that are held for the production of passive income is at least 50%. In addition, whether our Company will be a PFIC for any taxable year depends on our assets and income over the course of each such taxable year and, as a result, cannot be predicted with certainty until after the end of the year.

Based upon our assets and income during the course of 2014, we believe that our Company and one of our Company’s wholly-owned subsidiaries, Theravance Biopharma R&D, Inc. was a PFIC for 2014. Based upon our assets and income from 2015 through 2023, we do not believe that our Company is a PFIC since 2015. Based on existing tax law, we do not expect to be a PFIC for the foreseeable future based on our current business plans and current business model. For any taxable year (or portion thereof) in which our Company is a PFIC that is included in the holding period of a US holder, the US holder is generally subject to additional US federal income taxes plus an interest charge with respect to certain distributions from Theravance Biopharma or gain recognized on a sale of Theravance Biopharma shares. Similar rules would apply with respect to distributions from or gain recognized on an indirect sale of Theravance Biopharma Ireland Limited. US holders of our ordinary shares may have filed an election with respect to Company shares held at any time during 2014 to be treated as owning an interest in a “qualified electing fund” (“QEF”) or to “mark to market” their ordinary shares to avoid the otherwise applicable interest charge consequences of PFIC treatment with respect to our ordinary shares. A foreign corporation will not be treated as a QEF for any taxable year in which such foreign corporation is not treated as a PFIC. QEF and mark to market elections generally apply to the taxable year for

35

Table of Contents

which the election is made and all subsequent taxable years unless the election is revoked with consent of the Secretary of Treasury. US holders of our ordinary shares should consult their tax advisers regarding the tax reporting implications with respect to any QEF and mark to market elections made with respect to our Company and with respect to their indirect interests in Theravance Biopharma R&D, Inc.

If we are unable to maintain effective internal controls, our business, financial position, and results of operations could be adversely affected.

If we are unable to maintain effective internal controls, our business, financial position, and results of operations could be adversely affected. We are subject to the reporting and other obligations under the Exchange Act, including the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, which require annual management assessments of the effectiveness of our internal control over financial reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) under the Exchange Act. Our 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 accounting principles generally accepted in the US. Any failure to achieve and maintain effective internal controls could have an adverse effect on our business, financial position, and results of operations. These reporting and other obligations place significant demands on our management and administrative and operational resources, including accounting resources.

RISKS RELATED TO LEGAL AND REGULATORY UNCERTAINTY

​

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

We rely upon a combination of patents, patent applications, trade secret protection and confidentiality agreements to protect the intellectual property related to our technologies. Any involuntary disclosure to or misappropriation by third parties of this proprietary information could enable competitors to quickly duplicate or surpass our technological achievements, thus eroding our competitive position in our market. The status of patents in the biotechnology and pharmaceutical field involves complex legal and scientific questions and is very uncertain. As of December 31, 2023, we owned a total of 176 issued US patents and 1,002 granted foreign patents, as well as additional pending US and foreign patent applications. Our patent applications may be challenged or fail to result in issued patents and our existing or future patents may be invalidated or be too narrow to prevent third parties from developing or designing around these patents, including the patents that relate to YUPELRI. If the sufficiency of the breadth or strength of protection provided by our patents with respect to a product candidate is threatened, it could dissuade companies from collaborating with us to develop product candidates and threaten our ability to commercialize products. Further, if we encounter delays in our clinical trials or in obtaining regulatory approval of our product candidates, the effective patent lives of the related product candidates could be reduced.

In addition, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable, for processes for which patents are difficult to enforce and for any other elements of our drug discovery and development processes that involve proprietary know-how, information and technology that is not covered by patent applications. Although we require our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information and technology to enter into confidentiality agreements, we cannot be certain that this know-how, information and technology will not be misappropriated, disclosed or used for unauthorized purposes or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Further, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the US. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the US and abroad. If we are unable to prevent material disclosure of the intellectual property related to our technologies to third parties, we will not be able to establish or, if established, maintain a competitive advantage in our market, which could materially adversely affect our business, financial condition, and results of operations, which could cause the price of our securities to fall.

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

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

In the event of a successful claim of infringement against us, we may have to pay substantial damages, obtain one or more licenses from third parties or pay royalties. In addition, even in the absence of litigation, we may need to obtain licenses from third parties to allow commercialization of our product candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could harm our business significantly.

In addition, we have initiated, and in the future we could again be required to initiate, litigation to enforce our proprietary rights against infringement by third parties, prevent the unauthorized use or disclosure of our trade secrets and confidential information, or defend the validity of our patents. For example, in 2017, we filed a lawsuit against a former employee for misappropriation of certain of our confidential, proprietary and trade secret information. While this litigation has since been resolved, prosecution of claims to enforce or defend our rights against others involve substantial litigation expenses and divert substantial employee resources from our business but may not result in adequate remedy to us or sufficiently mitigate the harm to our business caused by any intellectual property infringement, unauthorized access, use or disclosure of trade secrets. For example, in February 2023, we filed patent infringement lawsuits against seven companies and certain of their affiliates seeking to market a generic version of YUPELRI, and in December 2023, we amended the lawsuit to include several non-Orange Book listed patents. Additional lawsuits were filed later in 2023 and into 2024 based on newly-issued patents. If these companies are found not to infringe one or more of our patents or the litigation results in one or more of our patents being invalidated, the generic companies may be able to launch their products prior to the expiration of the patents, which range from 2028 to 2039. Our collaboration partner, Viatris, is responsible for enforcing our Orange Book patents relating to YUPELRI, in consultation with us, and their views on the ongoing litigation, process or strategy may differ from ours, and we have a reduced ability to control the outcome of the litigation. For additional discussion of risks related to partnering programs, please see the risk factor entitled “If we are unable to enter into future collaboration arrangements or if any such collaborations with third parties are unsuccessful, we may be unable to fully develop and commercialize certain product candidates and our business will be adversely affected.” If we fail to effectively enforce our proprietary rights against others, our business will be harmed and the price of our securities could fall.

​

If the efforts of our partners or future partners to protect the proprietary nature of the intellectual property related to collaboration assets are not adequate, the future commercialization of any medicines resulting from collaborations could be negatively impacted, which would materially harm our business and could cause the price of our securities to fall.

The risks identified in the two preceding risk factors may also apply to the intellectual property protection efforts of our partners or future partners and to GSK with respect to TRELEGY in which we maintain the Ongoing Economic Interest. To the extent the intellectual property protection of any partnered assets is successfully challenged or encounters problems with the US Patent and Trademark Office or other comparable agencies throughout the world, the future commercialization of these potential medicines could no longer be economically feasible. Any challenge to the intellectual property protection of a late-stage development or commercial-stage asset, particularly those of TRELEGY, could harm our business and cause the price of our securities to fall.

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

The risk that we may be sued on product liability claims is inherent in the development and commercialization of pharmaceutical products. Side effects of, or manufacturing defects in, products that we or our partners develop or commercialize could result in the deterioration of a patient’s condition, injury or even death. Once a product is approved for sale and commercialized, the likelihood of product liability lawsuits tends to increase. Claims may be brought by individuals seeking relief for themselves or by individuals or groups seeking to represent a class, asserting injuries based both on potential adverse effects described in the label as well as adverse events not yet observed. We also face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials. In addition, changes in laws outside the US are expanding our potential liability for injuries that occur during clinical trials. Product liability claims could harm our reputation, regardless of the merit or ultimate success of the claim, which may adversely affect our and our partners’ ability to commercialize our products and cause the price of our securities to fall. These lawsuits may divert our management from pursuing our business strategy and may be costly to defend. In addition, if we are held liable in any of these lawsuits, we may incur substantial liabilities and may be forced to limit or forgo further commercialization of the applicable products.

Although we maintain general liability and product liability insurance, this insurance may not fully cover potential liabilities and we cannot be sure that our insurer will not disclaim coverage as to a future claim. In addition, inability to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims could prevent or inhibit the commercial production and sale of our products, which could adversely affect our business.

We may also be required to prosecute or defend general commercial, intellectual property, securities and other lawsuits. Litigation typically involves substantial expenses and diverts substantial employee resources from our business. The cost of defending any product liability litigation or engaging in any other legal proceeding, even if resolved in our favor, could be substantial and uncertainties resulting from the initiation and continuation of the litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace and achieve our business goals.

If we fail to comply with data protection laws and regulations, we could be subject to government enforcement actions (which could include civil or criminal penalties), private litigation and/or adverse publicity, which could negatively affect our operating results and business.

We are subject to data protection laws and regulations (i.e., laws and regulations that address privacy and data security). In the US, numerous federal and state laws, and regulations, including state data breach notification laws, state health information and/or genetic privacy laws, and federal and state consumer protection laws (e.g., Section 5 of the FTC Act), govern the collection, use, disclosure, and protection of health related and other personal information. In California, the California Consumer Privacy Act (“CCPA”) establishes certain requirements for data use and sharing transparency, and provides California residents certain rights concerning the use, disclosure, and retention of their personal data. The California Privacy Rights Act (“CPRA”) currently in effect, significantly amends the CCPA. Virginia, Colorado, Utah, Indiana, Iowa, Tennessee, Montana, Texas, and Connecticut have enacted privacy laws similar to the CCPA that impose new obligations or limitations in areas affecting our business. These laws and regulations are evolving and subject to interpretation and may impose limitations on our activities or otherwise adversely affect our business. The obligations to comply with the CCPA and evolving legislation involve, among other things, updates to our notices and the development of new processes internally and with our partners. We may be subject to fines, penalties, or private actions in the event of non-compliance with such laws.

In addition, we may obtain health information from third parties (e.g., healthcare providers who prescribe our products) that are subject to privacy and security requirements under the Health Insurance Portability and Accountability Act of 1996, the Health Information Technology for Economic and Clinical Health Act, and their implementing regulations, (collectively, “HIPAA”). HIPAA imposes privacy and security obligations on covered entity health care providers, health plans, and health care clearinghouses, as well as their “business associates”—certain persons or entities that create, receive, maintain, or transmit protected health information in connection with providing a specified service or performing a function on behalf of a covered entity. Although we are not directly subject to HIPAA, we could be

subject to criminal penalties if we knowingly receive individually identifiable health information maintained by a HIPAA covered entity in a manner that is not authorized or permitted by HIPAA.

Further at the federal level, the Federal Trade Commission (“FTC”) also sets expectations for failing to take appropriate steps to keep consumers’ personal information secure, or failing to provide a level of security commensurate to promises made to individual about the security of their personal information (such as in a privacy notice) may constitute unfair or deceptive acts or practices in violation of Section 5(a) of the Federal Trade Commission Act (“FTC Act”). The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits stronger safeguards. With respect to privacy, the FTC also sets expectations that companies honor the privacy promises made to individuals about how the company handles consumers’ personal information; any failure to honor promises, such as the statements made in a privacy policy or on a website, may also constitute unfair or deceptive acts or practices in violation of the FTC Act. While we do not intend to engage in unfair or deceptive acts or practices, the FTC has the power to enforce promises as it interprets them, and events that we cannot fully control, such as data breaches, may be result in FTC enforcement. Enforcement by the FTC under the FTC Act can result in civil penalties or enforcement actions.

EU Member States and other jurisdictions where we operate, such as Switzerland and the UK, have adopted data protection laws and regulations, which impose significant compliance obligations. For example, the General Data Protection Regulation (“GDPR”), imposes strict obligations and restrictions on the ability to collect, analyze, use, store, disclose. transfer or otherwise process personal data, including health data from clinical trials subjects and adverse event reporting. Switzerland has adopted laws that impose restrictions and obligations similar to the GDPR. The GDPR and Switzerland’s data protection laws impose a broad range of requirements and obligations relating to the processing and protection of personal data, including obligations to having legal bases for processing personal data (which may result in some instances in obtaining the consent of the individuals to whom the personal data relate), providing detailed information about the processing activities to the individuals, dealing with restrictions on sharing of personal data with third parties and transferring personal data out of the European Economic Area (“EEA”) or Switzerland, having contracting arrangements in place where required (such as with clinical trial sites and vendors), notifying in certain instances personal data breaches to data protection authorities and/or affected individuals, appointing data protection officers, conducting data protection impact assessments, responding to privacy rights requests and keeping records of processing activities. . Data protection authorities from the different EU Member States and the EEA may interpret the GDPR and applicable related national laws differently which could effectively result in requirements additional to those currently understood to apply under the GDPR. In addition, guidance on implementation and compliance practices may be updated or otherwise revised, which adds to the complexity of processing personal data in the EU. When processing personal data of subjects in the EU, we have to comply with applicable data protection and electronic communications laws. In particular, as we rely on service providers processing personal data of data subjects in the EU, we have to enter into suitable contract terms with such providers and receive sufficient guarantees that such providers meet the requirements of the applicable data protection laws, particularly the GDPR which imposes specific and relevant obligations. Enforcement by EU and UK regulators is active, and failure to comply with the GDPR or applicable Member State law may result in substantial fines. The GDPR increases substantially the penalties to which we could be subject in the event of any non-compliance, including fines of up to 10,000,000 Euros or up to 2% of our total worldwide annual turnover for certain comparatively minor offenses, or up to 20,000,000 Euros or up to 4% of our total worldwide annual turnover for more serious offenses. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with data protection authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR.

With regard to transfer of personal data, the GDPR restricts the ability of companies to transfer personal data from the EU to the U.S. and other countries, which may incur compliance costs for implementing lawful transfer mechanisms, conducting data transfer impact assessments, and implementing additional measures where necessary to ensure that personal data transferred are adequately protected in a manner essentially equivalent to the EU. The GDPR provides different transfer mechanisms we can use to lawfully transfer personal data from the EU to countries outside the EU. An example is relying on the EU Standard Contractual Clauses as approved by the European Commission in June 2021. Compliance with EU data transfer obligations can be costly and time-consuming. Data importers must also expend resources in analyzing their ability to comply with transfer obligations, including implementing new safeguards

and controls to further protect personal data. If we or our vendors fail to comply with applicable data privacy laws concerning, or if the legal mechanisms we or our vendors rely upon to allow, the transfer of personal data from the EEA or Switzerland to the US (or other countries not considered by the European Commission to provide an adequate level of data protection) are not considered adequate, we could be subject to government enforcement actions, including an order to stop transferring the personal data outside of the EEA and significant penalties against us. Moreover, our business could be adversely impacted if our ability to transfer personal data out of the EEA, the UK or Switzerland to the US is restricted, which could adversely impact our operating results.

Failure to comply with data protection laws and regulations could result in unfavorable outcomes, including increased compliance costs, delays or impediments in the development of new products, increased operating costs, diversion of management time and attention, government enforcement actions and create liability for us (which could include civil, administrative, and/or criminal penalties), private litigation and/or adverse publicity that could negatively affect our operating results and business.

Changes in healthcare law and implementing regulations, including government restrictions on pricing and reimbursement, as well as healthcare policy and other healthcare payor cost-containment initiatives, may negatively impact us, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties.

The continuing efforts of the government, insurance companies, managed care organizations and other payors of health care costs to contain or reduce costs of health care may adversely affect us, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties in regard to one or more of the following:

​

​

​

The pricing and reimbursement environment for products may change in the future and become more challenging due to, among other reasons, policies advanced by the presidential administration, federal agencies, new healthcare legislation passed by Congress or fiscal challenges faced by all levels of government health administration authorities. Among policy makers and payors in the US and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality, and expanding access to healthcare. In the US, the pharmaceutical industry has been a particular focus of these efforts and has been and may in the future be significantly affected by major regulatory or legislative initiatives, including those related to pricing of or reimbursement for prescription drugs. We expect we, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties may experience pricing pressures in connection with the sale of drug products, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative enactments and administrative policies.

The Patient Protection and Affordable Care Act, as amended (the “Healthcare Reform Act”), contains a number of provisions that impact our business and operations, including those governing enrollment in federal healthcare programs, reimbursement changes, benefits for patients within a coverage gap in the Medicare Part D prescription drug program (commonly known as the “donut hole”; the coverage gap will be eliminated effective 2025 under the Inflation Reduction Act and will be replaced with a new manufacturer discount program), rules regarding prescription drug benefits under the health insurance exchanges, changes to the Medicare Drug Rebate program, expansion of the Public Health Service Act’s 340B drug pricing program, fraud and abuse and enforcement. These changes have impacted previously existing government healthcare programs and have resulted in the development of new programs, including Medicare payment for performance initiatives and improvements to the physician quality reporting system and feedback program.

Certain provisions of the Healthcare Reform Act have been subject to judicial challenges as well as efforts to modify them or to alter their interpretation or implementation and additional legislative changes to and regulatory

40

Table of Contents

changes under the Healthcare Reform Act remain possible, but the nature and extent of such potential additional changes are uncertain at this time. We expect that the Healthcare Reform Act, its implementation, efforts to modify, or invalidate the Healthcare Reform Act, or portions thereof, or its implementation, and other healthcare reform measures including those that may be adopted in the future, could have a material adverse effect on our industry generally and on the ability of us, our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties to maintain or increase sales of existing products or to successfully commercialize product candidates, if approved.

The Bipartisan Budget Act of 2018, among other things, amended the Healthcare Reform Act to increase the point-of-sale discounts that manufacturers must agree to offer under the Medicare Part D coverage discount program from 50% to 70% off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. Civil monetary penalties can be applied if a manufacturer fails to provide these discounts in the amount of 125 percent of the discount that was due (the coverage gap has been eliminated effective 2025 under the Inflation Reduction Act).

The Budget Control Act of 2011, among other things, and in concert with subsequent legislation, has resulted in aggregate reductions to Medicare payments to providers of, on average, 2% per fiscal year through 2031. Sequestration is currently set at 2% and will increase to 2.25% for the first half of fiscal year 2030, to 3% for the second half of fiscal year 2030, and to 4% for the remainder of the sequestration period that lasts through the first six months of fiscal year 2031. As long as these cuts remain in effect, they could adversely impact payment for any products that are reimbursed under Medicare.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022 (the “IRA”). The IRA sunsets the coverage gap discount program starting in 2025 and replaces it with a new manufacturer discount program and establishes Part B and Part D inflation rebates. The IRA also creates a Drug Price Negotiation Program under which the prices for Medicare units of certain high Medicare spend drugs and biologics without generic or biosimilar competition will be capped by reference to, among other things, a specified non-federal average manufacturer price, with negotiated prices set to take effect starting in 2026. Failure to comply with requirements under the drug price negotiation program is subject to an excise tax and/or a civil monetary penalty. Whether any of our products are selected for negotiation for a given year will depend on whether they are at least 7 years post-approval/licensure; whether they meet any of the exclusions from eligibility for selection for negotiation, such as the exclusion of certain orphan drugs; their expenditures under Medicare Part B or Part D during a statutorily specified period; and whether a generic of the product has been determined to have come to market. Ampreloxetine received an Orphan Drug Designation status from the FDA, which should mean it will not be selected for negotiation; however, our understanding of whether and when our products are likely to be subject to selection for negotiation could evolve as the Drug Price Negotiation Program is implemented. These or any other legislative change could impact the market conditions for our products. We further expect continued scrutiny on pricing from Congress, agencies, and other bodies with respect to drug pricing.

Individual states in the US have also increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement limitations, marketing cost disclosure and transparency measures, and, in some cases, measures designed to encourage importation from other countries and bulk purchasing. For example, California has enacted a prescription drug price transparency law requiring prescription drug manufacturers to provide advance notice and explanation for price increases of certain drugs with prices that exceed a specified threshold, and to report new prescription drugs introduced to the market at a wholesale acquisition cost exceeding the Medicare Part D specialty drug threshold. Additionally, some individual states have begun establishing Prescription Drug Affordability Boards (or similar entities) to review high-cost drugs and, in some cases, set upper payment limits.

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 product or additional pricing pressures for our collaboration partners, or those commercializing products with respect to which we have an economic interest or right to receive royalties, which could impact our revenues.

If we failed to comply with our reporting and payment obligations under the Medicaid Drug Rebate program or other governmental pricing programs, we could be subject to additional reimbursement requirements, penalties, sanctions and fines, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Prior to the sale of VIBATIV to Cumberland Pharmaceuticals Inc. (“Cumberland”) in November 2018, we had certain price reporting obligations to the Medicaid Drug Rebate program and other governmental pricing programs, and we had obligations to report average sales price under the Medicare program. Following the consummation of the transaction with Cumberland, our price reporting obligations related to VIBATIV have been transitioned to Cumberland, and price reporting obligations for YUPELRI reside with Viatris. We retain certain obligations with respect to record retention for these programs. These programs included the following:

​

​

A manufacturer that becomes aware that its Medicaid reporting for a prior quarter was incorrect, or has changed as a result of recalculation of the pricing data, is obligated to resubmit the corrected data for up to three years after those data originally were due. Such restatements and recalculations increase the costs for complying with the laws and regulations governing the Medicaid Drug Rebate program and could result in an overage or underage in our rebate liability for past quarters. Price recalculations also may affect the 340B ceiling price and the average sales price. Manufacturers may need to make additional restatements beyond the three-year period.

We may be liable for errors associated with our submission of pricing data for VIBATIV for historic periods, and we may retain some liability for price reporting by Cumberland for VIBATIV sold under our labeler code. In addition to retroactive rebates and the potential for 340B program refunds, if we are found to have knowingly submitted any false price information to the government, we may be liable for significant civil monetary penalties per item of false information. If we are found to have made a misrepresentation in the reporting of our average sales price, the Medicare statute provides for significant civil monetary penalties for each misrepresentation for each day in which the misrepresentation was applied. If we are found to have charged 340B covered entities more than the statutorily mandated ceiling price, we could be subject to significant civil monetary penalties and/or such failure also could be grounds for HRSA to terminate a manufacturer’s agreement to participate in the 340B program, in which case covered outpatient drugs under our labeler code may no longer be eligible for federal payment under the Medicaid or Medicare Part B program. If we are found to have not submitted required price data on a timely basis, that could result in a significant civil monetary penalty per day for each day the information is late beyond the due date.

In order to be eligible to have its products paid for with federal funds under the Medicaid and Medicare Part B programs and purchased by the Department of Veterans Affairs (“VA”), Department of Defense (“DoD”), Public Health Service, and Coast Guard (the “Big Four agencies”) and certain federal grantees, a manufacturer is required to list its innovator products on a VA Federal Supply Schedule (“FSS”) contract and charge a price to the Big Four agencies that is no higher than the Federal Ceiling Price (“FCP”), which is a price calculated pursuant to a statutory formula. In addition, manufactures must submit to the VA quarterly and annual “non-federal average manufacturer price” (“Non-FAMP”) calculations for each NDC-11 of their innovator drugs. Under Section 703 of the National Defense

42

Table of Contents

Authorization Act for FY 2008, the manufacturer is required to pay quarterly rebates to DoD on utilization of its innovator products that are dispensed through DoD’s Tricare network pharmacies to Tricare beneficiaries.

Individual states in the US, as noted, have also passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including establishing Prescription Drug Affordability Boards (or similar entities) to review high-cost drugs and, in some cases, set upper payment limits and implementing marketing cost disclosure and transparency measures. Some states require the submission of reports related to pricing information, including based on the introduction of new prescription drugs, certain increases in wholesale acquisition cost of prescription drugs, marketing of prescription drugs within the state, and sales of prescription drugs in or into the state. Some states may pursue available enforcement measures, including imposition of civil monetary penalties, for a manufacturer’s failure to report such information.

​

The coverage and reimbursement status of new or current products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for new or current products could limit our ability to market those products and decrease our ability to generate revenue.

​

Market acceptance and sales of any one or more of our product candidates will depend on reimbursement policies and may be affected by future healthcare reform measures in the US. Government authorities and third-party payers, such as private health insurers and health maintenance organizations, decide which drugs they will cover and establish payment levels. We cannot be certain that reimbursement will be available for any commercialized products. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for, our products. If reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize any product candidates that we develop.

The pricing, coverage and reimbursement of our product candidates, if commercialized, must be adequate to support our commercial infrastructure. Our per-patient prices must be sufficient to recover our development and manufacturing costs and potentially achieve profitability. However, sales of any pharmaceutical product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. One third-party payor’s decision to cover a product does not ensure that other payors will also provide coverage for the product. As a result, we do not have assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.

In addition, third-party payors are increasingly reducing reimbursements for pharmaceutical products and services. The US government and state legislatures have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement, and requirements for substitution of generic products. Third-party payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost effectiveness of pharmaceutical products, in addition to questioning their safety and efficacy. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Further, such payors are increasingly challenging the price, examining the medical necessity and reviewing the cost effectiveness of medical product candidates. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit or delay sales of any of our future products. A decision by a third-party payor not to cover a product could reduce physician ordering and patient demand for any of our future products.

​

Our relationships with customers and third-party payors are subject to applicable anti-kickback, fraud and abuse, transparency and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, exclusion, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians, distributors, and third-party payors play a primary role in the distribution, recommendation, and prescription of any pharmaceutical product for which we obtain marketing approval. Our arrangements with third-party payors and customers expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements through which we market, sell

and distribute any products for which we have obtained or may obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations include the following:

​

The shifting commercial compliance environment and the need to build and maintain robust and expandable systems to comply with different compliance or reporting requirements in multiple jurisdictions increase the possibility that we or our partners may fail to comply fully with one or more of these requirements. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with applicable fraud and abuse or other healthcare laws and regulations or guidance. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, exclusion from government funded healthcare programs, such as Medicare and Medicaid in the US and similar programs outside the US, contractual damages, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. If any of the physicians or other providers or entities with whom we do or expect to do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our financial condition and divert resources and the attention of our management from operating our business.

Our business and operations, including the use of hazardous and biological materials may result in liabilities with respect to environmental, health and safety matters.

Our drug development activities involve the controlled use of potentially hazardous substances, including chemical, biological, and radioactive materials. In addition, our operations produce hazardous waste products, including hazardous waste. Federal, state, and local laws and regulations govern the use, manufacture, management, storage, handling and disposal of hazardous materials and wastes. We may incur significant additional costs or liabilities to comply with, or for violations of, these and other applicable laws in the future. Also, even if we are in compliance with applicable laws, we cannot completely eliminate the risk of contamination or injury resulting from hazardous materials and we may incur liability as a result of any such contamination or injury. Further, in the event of a release of or exposure to hazardous materials, including at the sites we currently or formerly operate or at sites such as landfills where we send wastes for disposal, we could be held liable for cleanup costs or damages or subject to other costs or penalties and such liability could exceed our resources. We do not have any insurance for liabilities arising from hazardous materials or under environmental laws. Compliance with or liability under applicable environmental laws and regulations or with respect to hazardous materials may be expensive, and current or future environmental regulations may impair our development and production efforts, which could harm our business, which could cause the price of our securities to fall.

RISKS RELATING TO OUR ORDINARY SHARES

​

The market price for our shares has and may continue to fluctuate widely and may result in substantial losses for purchasers of our ordinary shares.

The market price for our shares has fluctuated and may continue to fluctuate and may result in substantial losses for purchasers of our ordinary shares. For example, in the year ended December 31, 2023, the last reported sales price of our ordinary shares on Nasdaq fluctuated between a low of $8.38 per share and a high of $11.92 per share. To the extent that low trading volumes for our ordinary shares continues, our stock price may fluctuate significantly more than the stock market as a whole or the stock prices of similar companies. Without a larger public float of actively traded shares, our ordinary shares are likely to be more sensitive to changes in sales volumes, market fluctuations and events or perceived events with respect to our business, than the shares of common stock of companies with broader public ownership, and as a result, the trading prices for our ordinary shares may be more volatile. Among other things, trading of a relatively small volume of ordinary shares may have a greater effect on the trading price than would be the case if our public float of actively traded shares were larger. In addition, as further described below under the risk factor entitled “—Concentration of ownership will limit your ability to influence corporate matters,” a number of shareholders hold large concentrations of our shares which, if sold to third parties within a relatively short timeframe, could cause the price of our shares to drop significantly.

Market prices for securities of biotechnology and biopharmaceutical companies have been highly volatile, and we expect such volatility to continue for the foreseeable future, so that investment in our ordinary shares involves substantial risk. Additionally, the stock market from time to time has experienced significant price and volume fluctuations unrelated to the operating performance of particular companies.

The following are some of the factors that may have a significant effect on the market price of our ordinary shares:

If any of these factors causes us to fail to meet the expectations of securities analysts or investors, or if adverse conditions prevail or are perceived to prevail with respect to our business, the price of the ordinary shares would likely drop significantly. For example, our stock price dropped significantly when we announced that izencitinib did not meet its primary endpoint in our Phase 2b/3 induction and maintenance study of izencitinib in ulcerative colitis. In addition, though none has been filed to our knowledge, a significant drop in the price of a company’s securities often leads to the filing of securities class action litigation against the company. This type of litigation against us could result in substantial costs and a diversion of management’s attention and resources.

Activist shareholders could negatively impact our business and cause disruptions.

We value constructive input from investors and regularly engage in dialogue with our shareholders regarding strategy and performance. While our board of directors and management team welcome their views and opinions with the goal of enhancing value for all shareholders, we may be subject to actions or proposals from activist shareholders that may not align with our business strategies or the best interests of all of our shareholders.

​

For example, in February 2023, Irenic Capital Management LP (“Irenic”) released a public letter communicating its opinions regarding actions that it believes we should take and made public statements critical of our board of directors and management. Irenic may continue to make and/or other activist shareholders may make such public communications in the future.

​

In the event of such shareholder activism – particularly with respect to matters which our board of directors, in exercising their fiduciary duties, disagree with or have determined not to pursue – our business could be adversely affected because responding to such actions by activist shareholders can be costly and time-consuming, disruptive to our operations and divert the attention of management, our board of directors and our employees, and our ability to execute our strategic plan could also be impaired as a result. Such an activist campaign could require us to incur substantial legal, public relations and other advisory fees and proxy solicitation expenses. Further, we may become subject to, or we may initiate, litigation as a result of proposals by activist shareholders or matters relating thereto, which could be a further distraction to our board of directors and management and could require us to incur significant additional costs. In addition, perceived uncertainties as to our future direction, strategy, or leadership created as a consequence of activist shareholders may result in the loss of potential business opportunities, harm our ability to attract new or retain existing investors, customers, directors, employees, collaborators or other partners, harm or impair our ability to accrue patients to clinical trials because of concerns the study may be disrupted, disrupt relationships with us, and the market price of our ordinary shares could also experience periods of increased volatility as a result.

​

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

Based solely on our review of publicly available filings, as of December 31, 2023, our three largest shareholders collectively owned 45.5% of our outstanding ordinary shares. These shareholders could control the outcome of actions taken by us that require shareholder approval, including a transaction in which shareholders might receive a premium over the prevailing market price for their shares.

48

Table of Contents

Certain provisions in our constitutional and other documents may discourage our acquisition by a third-party, which could limit your opportunity to sell shares at a premium.

Our constitutional documents include provisions that could limit the ability of others to acquire control of us, modify our structure or cause us to engage in change-of-control transactions, including, among other things, provisions that:

​

​

​

​

​

In addition, in May 2018, our shareholders approved a resolution authorizing our board of directors to adopt a shareholder rights plan in the future intended to deter any person from acquiring more than 19.9% of our outstanding ordinary shares without the approval of our board of directors.

These provisions could have the effect of depriving you of an opportunity to sell your ordinary shares at a premium over prevailing market prices by discouraging third parties from seeking to acquire control of us in a tender offer or similar transaction.

Our shareholders may face difficulties in protecting their interests because we are incorporated under Cayman Islands law.

Our corporate affairs are governed by our amended and restated memorandum and articles of association, by the Companies Law (2020 Revision) of the Cayman Islands and by the common law of the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under the laws of the Cayman Islands are different from those under statutes or judicial precedent in existence in jurisdictions in the US. Therefore, you may have more difficulty in protecting your interests than would shareholders of a corporation incorporated in a jurisdiction in the US, due to the different nature of Cayman Islands law in this area.

Shareholders of Cayman Islands exempted companies such as our company have no general rights under Cayman Islands law to inspect corporate records and accounts or to obtain copies of lists of shareholders. Our directors have discretion under our amended and restated memorandum and articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

Our Cayman Islands counsel, Maples and Calder, is not aware of any reported class action having been brought in a Cayman Islands court. Derivative actions have been brought in the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability for such actions. In most cases, the Company will be the proper plaintiff in any claim based on a breach of duty owed to it, and a claim against (for example) our officers or directors usually may not be brought by a shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority and be applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which:

​

​

A shareholder may have a direct right of action against the company where the individual rights of that shareholder have been infringed or are about to be infringed.

There is uncertainty as to shareholders’ ability to enforce certain foreign civil liabilities in the Cayman Islands.

We are incorporated as an exempted company limited by shares with limited liability under the laws of the Cayman Islands. A material portion of our assets are located outside of the US. As a result, it may be difficult for our shareholders to enforce judgments against us or judgments obtained in US courts predicated upon the civil liability provisions of the federal securities laws of the US or any state of the US.

We understand that the courts of the Cayman Islands are unlikely (i) to recognize or enforce against Theravance Biopharma judgments of courts of the US predicated upon the civil liability provisions of the securities laws of the US or any State; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against Theravance Biopharma predicated upon the civil liability provisions of the securities laws of the US or any State, on the grounds that such provisions are penal in nature. However, in the case of laws that are not penal in nature, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the US, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands’ judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands court, including the Grand Court of the Cayman Islands, may stay proceedings if concurrent proceedings are being brought elsewhere, which would delay proceedings and make it more difficult for our shareholders to bring action against us.

If securities or industry analysts cease coverage of us or do not publish research, or publish inaccurate or unfavorable research, about our business, the price of our ordinary shares and trading volume could decline.

The trading market for our ordinary shares depends in part on the research and reports that securities or industry analysts publish about us or our business. If few securities analysts commence coverage of us, or if industry analysts cease coverage of us, the trading price for our ordinary shares could be negatively affected. If one or more of the analysts who cover us downgrade our ordinary shares or publish inaccurate or unfavorable research about our business or if our results fail to meet the expectations of these analysts, the price of our ordinary shares would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our ordinary shares could decrease, which might cause our share price and trading volume to decline.

Capital appreciation, if any, of our ordinary shares may be your sole source of gain for the foreseeable future.

We have never declared or paid cash dividends on our capital shares. Starting in September 2022, we undertook a capital return program of $325.3 million. As of December 31, 2023, we had repurchased $324.9 million of shares, and we repurchased the remaining $0.4 million in the capital return program during January 2024. There is no guarantee that we will implement another capital return program in the future. As a result, capital appreciation, if any, of our ordinary shares may be your sole source of gain for the foreseeable future.

We are a smaller reporting company, and any decision on our part to comply only with reduced reporting and disclosure requirements applicable to such companies could make our ordinary shares less attractive to investors.

As of June 30, 2023, we qualified as a “smaller reporting company,” as defined in the Exchange Act. For as long as we continue to be a smaller reporting company, we may choose to take advantage of exemptions from various

50

reporting requirements applicable to other public companies that are not smaller reporting companies, including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and only being required to provide two years of audited financial statements in annual reports. In addition, for so long as we remain a smaller reporting company and not classified as an “accelerated filer” or “large accelerated filer” pursuant to SEC rules, we will be exempt from the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act.

​

We will remain a smaller reporting company so long as, as of June 30 of the preceding year, (i) the market value of our ordinary shares held by non-affiliates, or our public float, is less than $250.0 million; or (ii) we have annual revenues less than $100.0 million and either we have no public float or our public float is less than $700.0 million.

​

If we take advantage of some or all of the reduced disclosure requirements available to smaller reporting companies, investors may find our ordinary shares less attractive, which may result in a less active trading market for our common stock and greater stock price volatility.

ITEM 1C. CYBERSECURITY

​

Risk Management and Strategy

We recognize the importance of maintaining the trust and confidence of our investors, patients, business partners, and employees. Our board of directors are actively involved in the oversight of our risk management program, and cybersecurity represents an important component of our overall approach to enterprise risk management (“ERM”). Our cybersecurity policies, standards, processes, and practices are fully integrated into our ERM program and are based on recognized frameworks established by the National Institute of Standards and Technology, the international organization for standardization. In general, we seek to address cybersecurity risks through a comprehensive cross-functional approach that is focused on preserving the confidentiality, security, and availability of the information that we collect and store by identifying, preventing, and mitigating cybersecurity threats and effectively responding to cybersecurity incidents when they occur.

​

Our cybersecurity program includes the following key elements:

​

We have implemented a comprehensive cross-functional approach to identifying, preventing, and mitigating cybersecurity threats and incidents, while also implementing controls and procedures that provide for the prompt escalation of certain cybersecurity incidents so that decisions regarding the public disclosure and reporting of such incidents can be made by management in a timely manner.

​

We deploy technical safeguards that are designed to protect our information systems from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality, and access controls, which are evaluated and improved through vulnerability assessments and cybersecurity threat intelligence.

​

We have established and maintain comprehensive incident response and recovery plans that address our response to a cybersecurity incident, and such plans are tested and evaluated on a regular basis.

​

Table of Contents

We maintain a comprehensive risk-based approach to identifying and overseeing cybersecurity risks presented by third parties, including vendors, service providers, and other external users of our systems, as well as the systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems.

​

We provide regular mandatory training for employees regarding cybersecurity threats as a means to equip our employees with effective tools and education to address cybersecurity threats and to communicate our evolving information security policies, standards, processes, and practices.

​

Governance

One of the key functions of our board of directors is informed oversight of our ERM, including risks from cybersecurity threats. Our board of directors receive regular presentations and reports on our cybersecurity risks, which have pertained to a wide range of topics including recent developments, evolving standards, vulnerability assessments, third-party and independent reviews, the threat environment, technological trends, and information security considerations arising with respect to our peers and third parties. The board of directors also receive prompt and timely information regarding any cybersecurity incident that meets reporting thresholds, as well as ongoing updates regarding any such incident until it has been addressed and resolved.

​

On an annual basis, the board of directors discuss our approach to cybersecurity risk management with management which includes our Chief Information Officer (“CIO”). Our CIO has overall operational responsibility for our cybersecurity risk management. To facilitate the success of our cybersecurity risk management program, we have an Infrastructure, Operations & Security Team (“IOS Team”) that is tasked with the responsibility to design, implement, and manage systems, processes, and policies to defend against cybersecurity threats and to respond to cybersecurity incidents. Working collaboratively across our Company, the IOS Team implements and maintains a program designed to protect our information systems from cybersecurity threats and to promptly respond to any cybersecurity incidents in accordance with our incident response and recovery plans.

​

ITEM 2. PROPERTIES

Our principal physical properties in the US consist of approximately 162,000 square feet of office and laboratory space leased in two buildings in South San Francisco, California. Of this office and laboratory space, approximately 99,000 square feet was subleased as of December 31, 2023. The South San Francisco lease expires in May 2030, and our subleases expire in September 2028 and May 2030. Our Irish subsidiary operates from approximately 700 square feet of leased office space in Dublin, Ireland, that expires in May 2024.

ITEM 3. LEGAL PROCEEDINGS

During January 2023, we received notice from Accord Healthcare, Inc.; Cipla USA, Inc. and Cipla Limited; Eugia Pharma Specialties Ltd.; Lupin Inc.; Mankind Pharma Ltd.; Orbicular Pharmaceutical Technologies Private Limited; and Teva Pharmaceuticals, Inc. (collectively, the “generic companies”), that they have each filed with the FDA an abbreviated new drug application (“ANDA”), for a generic version of YUPELRI. The notices from the generic companies each included a paragraph IV certification with respect to five of our patents listed in the FDA’s Orange Book for YUPELRI on the date of our receipt of the notice. The asserted patents relate generally to polymorphic forms of and a method of treatment using YUPELRI. In February 2023, we filed patent infringement suits against the generic companies in federal district courts, including the United States District Court for the District of New Jersey, the U.S. District Court for the District of Delaware, and the U.S. District Court for the Middle District of North Carolina. The suits in Delaware and North Carolina have been dismissed, as all generic companies have agreed to venue in New Jersey. The complaint alleges that by filing the ANDAs, the generic companies have infringed five of our Orange Book listed patents. We are seeking a permanent injunction to prevent the generic companies from introducing a generic version of YUPELRI that would infringe its patents. As a result of this lawsuit, a stay of approval through May 2026 has been imposed by the FDA on the generic companies’ ANDAs pending any adverse court decision. Additional patents

52

Table of Contents

covering YUPELRI, granted on July 4, 2023 and January 2, 2024, were subsequently listed in FDA’s Orange Book. We filed additional patent infringement suits in the U.S. District Court for the District of New Jersey during August 2023 and January 2024. These suits have been consolidated with the above action. Further, the original complaint was amended during December 2023 to include certain patents not listed in the Orange Book.

​

As of February 28, 2024, we have settled all litigation with Accord Healthcare, Inc.; Lupin Pharmaceuticals, Inc.; Orbicular Pharmaceutical Technologies Private Limited; and Teva Pharmaceuticals, Inc. pursuant to individual agreements in which we granted these companies a royalty-free, non-exclusive, non-sublicensable, non-transferable license to manufacture and market their respective generic versions of YUPELRI inhalation solution in the US on or after the licensed launch date of April 23, 2039, subject to certain exceptions as is customary in these type of agreements. As required by law, the settlements are subject to review by the U.S. Department of Justice and the Federal Trade Commission. The patent litigation against the three remaining generic companies, along with certain affiliates, remains pending.

​

Please also see “Item 1, Business – Patents and Proprietary Rights -- Patent Term Restoration, Regulatory Exclusivities, and Hatch-Waxman Litigation” for additional information. In addition, this litigation and the related risks are described in greater detail under the risk factor “Litigation to protect or defend our intellectual property or third party claims of intellectual property infringement would require us to divert resources and may prevent or delay our drug discovery and development efforts” of this Annual Report on Form 10-K.

​

ITEM 5. MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our ordinary shares have traded on The Nasdaq Global Market under the symbol “TBPH” since June 3, 2014. As of February 23, 2024, there were 43 shareholders of record of our ordinary shares. As many of our ordinary shares are held by brokers and other institutions on behalf of shareholders, we are unable to estimate the total number of underlying shareholders represented by these shareholders of record.

​

Dividend Policy

We currently intend to retain any future earnings to finance our pharmaceutical development efforts. We have never declared or paid cash dividends on our ordinary shares and do not intend to declare or pay cash dividends on our ordinary shares in the foreseeable future.

​

Issuer Purchases of Equity Securities

On September 19, 2022, we announced that our board of directors had approved a $250.0 million share repurchase program, and on February 27, 2023, we announced that our board of directors had authorized a $75.0 million increase to the capital return program, bringing the total capital return program to $325.0 million. As of December 31, 2023, we had repurchased $324.8 million of shares, and, as of December 31, 2023, we had approximately $0.4 million remaining in the capital return program which was completed in early January 2024.

​

The table below summarizes information about the Company’s purchases of its equity securities registered pursuant to Section 12 of the Exchange Act during the three months ended December 31, 2023. All shares purchased under the repurchase program were cancelled and ceased to be outstanding.

Equity Compensation Plans

The following table provides certain information with respect to all of our equity compensation plans in effect as of December 31, 2023:

​

We have three equity compensation plans — our 2013 Equity Incentive Plan (the “2013 EIP”), as amended, our 2013 Employee Share Purchase Plan (the “2013 ESPP”), and our 2014 New Employee Equity Incentive Plan (the “2014 NEEIP”). At inception of the plans, we were authorized to issue 5,428,571 ordinary shares under the 2013 EIP and 857,142 ordinary shares under the 2013 ESPP, and 750,000 ordinary shares under the 2014 NEEIP.

​

The 2013 EIP provides for the issuance of share-based awards, including restricted shares, restricted share units, options, share appreciation rights (“SARs”) and other equity-based awards, to our employees, officers, directors, and consultants. Options may be granted with an exercise price not less than the fair market value of the ordinary shares on the grant date. Under the terms of our 2013 EIP, options granted to employees generally have a maximum term of 10 years and vest over a four-year period from the date of grant; 25% vest at the end of one year, and 75% vest monthly over the remaining three years. We may grant options with different vesting terms from time to time. Unless an employee’s termination of service is due to disability or death, upon termination of service, any unexercised vested options will generally be forfeited at the end of three months or the expiration of the option, whichever is earlier.

​

At the our Annual General Meeting of Shareholders on May 2, 2023, shareholders approved an amendment and restatement of the 2013 EIP to effect the following material changes to the existing plan (i) extend the term of the 2013 EIP by an additional ten years to February 14, 2033; (ii) eliminate the provision that provided for automatic annual increases in the number of shares available for issuance under the 2013 EIP; (iii) reduce the number of shares reserved for issuance by 3,808,287 shares; (iv) eliminate our ability to reprice options and share appreciation rights without first obtaining shareholder approval; and (v) remove certain provisions no longer necessary since the repeal of the exemption from the annual deduction limitation imposed by Section 162(m) of the Internal Revenue Code for performance-based compensation.

​

Under the 2013 ESPP, our officers and employees may purchase ordinary shares through payroll deductions at a price equal to 85% of the lower of the fair market value of the ordinary share at the beginning of the offering period or at the end of each applicable purchase period. As of January 1 of each year, commencing on January 1, 2015 and ending on (and including) January 1, 2033, the aggregate number of ordinary shares that may be issued under the 2013 ESPP shall automatically increase by a number equal to the least of (i) 1% of the total number of ordinary shares outstanding on December 31 of the prior year; (ii) 857,142 ordinary shares; or (iii) a number of ordinary shares determined by our board of directors. The ESPP generally provides for consecutive and overlapping offering periods of 24 months in duration, with each offering period generally 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. Our 2013 ESPP also includes a feature that provides for the existing offering period to terminate

55

Table of Contents

and for participants in that offering period to automatically be enrolled in a new offering period when the fair market value of an ordinary share at the beginning of a subsequent offering period falls below the fair market value of an ordinary share on the first day of such offering period.

​

The 2014 NEEIP provides for the issuance of share-based awards, including restricted shares, restricted share units, non-qualified options and SARs, to our employees. Options may be granted with an exercise price not less than the fair market value of the ordinary shares on the grant date. Under the terms of our 2014 NEEIP, options granted to employees generally have a maximum term of 10 years and vest over a four-year period from the date of grant; 25% vest at the end of one year, and 75% vest monthly over the remaining three years. We may grant options with different vesting terms from time to time. Unless an employee’s termination of service is due to disability or death, upon termination of service, any unexercised vested options will generally be forfeited at the end of three months or the expiration of the option, whichever is earlier.

​

Additional information regarding share-based compensation is included in “Item 8, Note 1. Organization and Summary of Significant Accounting Policies,” and “Item 8, Note 12. Share-Based Compensation,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Our Management’s Discussion and Analysis (“MD&A”) is intended to facilitate an understanding of our results of operations, as well as our liquidity and capital resources. Additionally, it describes accounting policies and estimates that management has deemed as “critical accounting policies and estimates.” This MD&A should be read in conjunction with our consolidated financial statements and notes included in this Annual Report on Form 10-K. The information contained in this MD&A or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, our operating expenses, and future payments under our collaboration agreements, includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). Such statements are based upon current expectations that involve risks and uncertainties. You should review the section entitled “Risk Factors” in Item 1A of Part I above for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. See the section entitled “Special Note regarding Forward-Looking Statements” on page 3 for more information.

​

Management Overview

Theravance Biopharma, Inc. (“we,” “our,” “Theravance Biopharma” or the “Company”) is a biopharmaceutical company primarily focused on the development and commercialization of medicines. Our focus is to create medicines that make a difference^® in people’s lives.

​

In pursuit of our purpose, we leverage decades of expertise, which has led to the development of the United States (“US”) Food and Drug Administration (the “FDA”) approved YUPELRI^® (revefenacin) inhalation solution indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (“COPD”). Ampreloxetine, our late-stage investigational once-daily norepinephrine reuptake inhibitor in development for the treatment of symptomatic neurogenic orthostatic hypotension (“nOH”) in patients with Multiple System Atrophy (“MSA”) has the potential to be a first in class therapy effective in treating a constellation of cardinal symptoms in MSA patients.

​

2023 Significant Developments

​

YUPELRI Sales Growth

In 2023, YUPELRI experienced sales growth and reached all-time high yearly net sales and profitability. Through the combined commercialization efforts with our partner Viatris Inc. (“Viatris”), total YUPELRI net sales increased by 9% to $221.0 million in 2023 compared to 2022. Hospital volumes, which we are directly responsible for, grew 46% in 2023 compared to 2022 and was a meaningful contributor to YUPELRI’s overall net sales growth for the year.

​

Initiation of Ampreloxetine New Phase 3 Clinical Study

In the first quarter of 2023, we initiated the ampreloxetine new Phase 3 clinical study (CYPRESS) in MSA patients with symptomatic nOH, using the Orthostatic Hypotension Symptom Assessment Scale (“OHSA”) composite score as the primary endpoint. In May 2023, we announced that the FDA granted Orphan Drug Designation status to ampreloxetine for the treatment of symptomatic nOH in patients with MSA. The study is currently enrolling patients with 42 clinical sites open across 11 countries, as of February 26, 2024.

​

Capital Return Program

In 2023, we repurchased 18.63 million of our shares on the open market at a weighted average cost of $10.551 per share for an approximate aggregate cost of $196.6 million, excluding fees and expenses. Since the inception of the capital return program in September 2022 through its completion in early January 2024, we repurchased a total of 31.41

57

Table of Contents

million shares at a weighted average cost of $10.354 per share for an approximate aggregate cost of $325.3 million which reduced our shares by 37% since the inception of the capital return program.

​

Discontinued Investment in Research

In February 2023, we announced that we discontinued our research activities, including the inhaled Janus kinase (JAK) inhibitor program, and prioritized our R&D resources toward the ampreloxetine Phase 3 study and the completion of the YUPELRI Peak Inspiratory Flow Rate (PIFR-2) Phase 4 study. As a result of halting further investment in research activities, our headcount was reduced by approximately 17% in March 2023. We plan to seek a partnership to continue progression of our inhaled JAK inhibitor program.

​

Board Governance Changes

In 2023, we appointed three new independent directors reflecting our ongoing commitment to bringing new perspectives and complementary skills to the Company. In addition, we put forth a proposal to declassify the board of the directors over time which was approved at our May 2023 Annual General Meeting of Shareholders.

​

See “Item 1. Business” starting on page 4 for a more complete discussion of our business.

​

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with US Generally Accepted Accounting Principles (“GAAP”). The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets, liabilities, and other related disclosures. 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 and estimates discussed below are essential to understanding our operating results and financial condition, as these policies and estimates relate to the more significant areas involving management’s judgments.

​

Future Contingent Milestone and Royalty Assets

The fair value of consideration received in connection with the sale of Theravance Respiratory Company, LLC (“TRC”) in July 2022 included an estimated $194.2 million in future contingent milestones and royalties that were recorded as a contingent consideration asset (“Contingent Consideration”) on our consolidated balance sheets on the transaction date. The Contingent Consideration was initially measured at fair value utilizing a Monte Carlo simulation model to calculate the present value of the risk-adjusted cash flows estimated to be received from the Contingent Consideration. The fair value model involved significant unobservable inputs derived using our estimates. Our estimates were based in part on external data and reflected our judgements and forecasts. The primary significant unobservable input was the estimate of forecasted TRELEGY ELLIPTA net revenues which is considered a Level 3 fair value input. We periodically reassess the carrying value of the Contingent Consideration when indicators of impairment are identified, and we will recognize an impairment loss if the carrying value materially exceeds the reassessed fair value. We recognize any increases in the carrying value of the Contingent Consideration only when such contingent gains are realized.

​

Future Royalty Payment Contingency

We treat contingent liabilities related to sale of future royalties as debt financings, amortized under the effective interest method over the estimated life of the related expected royalty stream. The contingent liabilities related to sale of future royalties and the debt amortization are based on current estimates of the amount and timing of future royalty payments, including the potential for any future funding milestones. We periodically reassess the amount and timing of estimated royalty payments based on internal sales projections and external information from market data sources, which are considered Level 3 inputs. To the extent our estimates of the amount and timing of future royalty payments are materially greater or less than previous estimates, we will prospectively adjust the amortization of the contingent liability and effective interest rate.

​

Results of Operations

The following tables set forth our results of operations and management’s commentary for the 2023 period compared to the 2022 period.

​

Revenue

While Viatris Inc. (“Viatris”) records the total net sales of YUPELRI within its own financial statements, our implied 35% YUPELRI revenue, as compared to the prior year period, was as follows:

​

​

Our recognized revenue, as compared to the prior year period, was as follows:

​

NM: Not Meaningful

We are entitled to a share of US profits and losses (65% to Viatris; 35% to Theravance Biopharma) received in connection with YUPELRI net sales. In accordance with the applicable accounting guidance, amounts receivable from Viatris in connection with the commercialization of YUPELRI are recorded within the consolidated statements of operations as revenue from “Viatris collaboration agreement”. Any reimbursement from Viatris attributed to the 65% cost-sharing of our R&D expenses is characterized as a reduction of R&D expense, as we do not consider performing R&D services for reimbursement to be a part of our ordinary operations.

​

In 2023 and 2022, we recognized $57.2 million and $48.6 million, respectively, in revenue from the Viatris collaboration agreement, which represented an increase of 18%. The increase was driven primarily by (i) an increase in net sales as YUPELRI continued to increase its share of the long-acting nebulized COPD market in both the hospital and outpatient settings; and (ii) lower costs incurred by Viatris. YUPELRI continued to be profitable for us on a brand basis, and total YUPELRI net sales recorded by Viatris reached an all-time high for 2023 and for the most recent fourth quarter of $221.0 million and $60.6 million, respectively.

​

Licensing revenue was $2.5 million in 2022 and was related to a non-recurring development milestone payment from Pfizer Inc. (“Pfizer”) for the first patient dosed in a Phase 1 clinical trial of the skin-selective pan-JAK inhibitor program. In June 2023, we received notice from Pfizer terminating the Pfizer licensing agreement, effective as of October 7, 2023, at which time the skin-selective pan-JAK inhibitor program was returned to us. We did not recognize any licensing revenue in 2023.

​

Research and Development

Our R&D expenses consist primarily of employee-related costs, external costs, and various allocable expenses. We budget total R&D expenses on an internal department level basis, and we manage and report our R&D activities across the following four cost categories:

​

​

59

Table of Contents

​

​

​

The following table summarizes our R&D expenses incurred, net of any reimbursements from collaboration partners, as compared to the prior year period:

​

​

R&D expenses decreased by $22.8 million in 2023, or 36%, compared to 2022. The decrease was across all R&D categories and was primarily driven by our 2023 Strategic Actions announced in February 2023 which included the discontinuation of investment in our research activities. The $3.7 million decrease in external-related expenses was partially offset by increases related to the progression of the ampreloxetine Phase 3 clinical study (CYPRESS) for MSA patients with symptomatic nOH, the completion of the YUPELRI Phase 4 study (PIFR-2), and the close out of discontinued programs.

​

R&D expenses directly attributed to the 2023 Strategic Actions and the restructuring announced in 2021 and completed during the third quarter of 2022 (the “2021 Restructuring”) are included in the Restructuring and Related Expenses section below.

​

Under certain of our collaborative arrangements, we receive partial reimbursement of employee-related costs and external costs, which have been reflected as a reduction of R&D expenses of $5.7 million and $6.7 million for 2023 and 2022, respectively.

​

Selling, General and Administrative

Selling, general and administrative (“SG&A”) expenses consist primarily of salaries and benefits, facilities and overhead costs, and other costs related to areas such as legal, finance, information technology, sales and marketing, and medical affairs.

​

SG&A expenses, as compared to the prior year period, were as follows:

​

​

In 2023, SG&A expenses increased by $3.0 million compared to 2022 and was primarily due to increases in external-related expenses of $4.9 million and SG&A allocated overhead expenses of $7.4 million. External-related expenses increased by $5.0 million and was primarily attributed to professional and financial advisory services and intellectual property protection services, such as the Hatch Waxman litigation, and the increase in SG&A allocated overhead expenses was driven by the reduction in our research activities which resulted in a larger absorption of such expenses by SG&A. Our cost reduction efforts led to decreases in employee-related expenses of $1.2 million, share-based compensation expenses of $2.9 million and facilities/other expenses of $5.1 million which partially offset the increases in external-related and allocated overhead expenses.

60

Table of Contents

​

Share-based compensation expense related to selling, general and administrative expenses was $17.0 million and $19.8 million for 2023 and 2022, respectively.

​

SG&A expenses that were directly attributed to the 2023 Strategic Actions and the 2021 Restructuring are included in the Restructuring and Related Expenses section below. Following our 2023 Strategic Actions, we placed approximately 42,000 square feet of vacant office and laboratory space in South San Francisco on the market for sublease in March 2023. As of December 31, 2023, we evaluated the carrying value of our operating lease assets and leasehold improvements associated with the sublease space (approximately $10.9 million) and determined that the carrying amount of these assets was fully recoverable. As a result, we did not recognize an impairment charge in 2023. However, as the sublease market continues to evolve, it is possible that we will need to adjust our assumptions and record an impairment charge (non-cash) in a future period.

​

Restructuring and Related Expenses

Restructuring and related expenses, as compared to the prior year period, were as follows:

​
