Business Description

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”). ​ Recent Significant Developments Ampreloxetine Phase 3 Clinical Study Top-line Results On March 3, 2026, we announced that our ampreloxetine Phase 3 clinical study (CYPRESS) in development for the treatment of symptomatic neurogenic orthostatic hypotension in patients with multiple system atrophy did not meet its primary endpoint in the Orthostatic Hypotension Symptom Assessment composite score. As a result of this outcome, we have decided to wind down the ampreloxetine program. ​ Strategic Review Committee In connection with the CYPRESS study results, the Strategic Review Committee of our Board of Directors (the "Committee") is accelerating its ongoing review of alternatives to maximize value for shareholders. Since its formation in 2024, the Committee has been working on an ongoing basis with Lazard, its independent financial advisor, to evaluate opportunities available to the Company, including under multiple potential outcomes for the CYPRESS study. Building upon this work, the Committee will act with urgency to evaluate a broad range of value maximizing and tax efficient alternatives, including but not limited to a sale of the Company. There can be no assurance that the Committee's strategic review process will result in any transaction. We do not intend to disclose further developments on this review process unless and until it determines that such disclosure is appropriate or necessary. As we proceed with the orderly wind down of the ampreloxetine program, we will complete additional analyses of the CYPRESS dataset and Phase 3 program, in consultation with external experts, to assess whether the data merits further regulatory discussion. This assessment is intended to provide the Committee with additional clarity regarding any remaining value in ampreloxetine for our shareholders. There can be no assurance that any additional regulatory engagement will occur. ​ Organizational Restructure While the Committee accelerates its review, we are implementing an organizational restructuring (the “Restructuring”) to streamline costs and align our resources with our commercial focus on YUPELRI. The Restructuring will involve winding down our R&D function and significantly reducing our G&A function. The Restructuring is expected to reduce operating expenses by approximately 60%, relative to 2025 operating expenses of $111.1 million. The full run-rate cost savings of approximately $70 million are expected to be realized beginning in the third quarter of 2026. ​ YUPELRI Net Sales Growth In 2025, YUPELRI experienced net sales growth and reached launch-to-date highs in annual net sales and brand profitability. Through the combined commercialization efforts with our partner Viatris Inc., total YUPELRI net sales increased by 12% to $266.6 million in 2025 compared to 2024. Customer demand grew 7% in 2025 compared to 2024. In addition, in January 2026, we received a $25.0 million milestone payment for the achievement of $250.0 million in US net sales in 2025. ​ 4 Table of Contents Sale of TRELEGY ® Royalties In June 2025, we sold our remaining royalty interest in the global net sales of TRELEGY to GSK plc for $225.0 million while retaining our right to receive up to $150.0 million in remaining potential milestone payments from Royalty Pharma Investments. The sales transaction represented the first outcome of the ongoing efforts of the Committee to assess all strategic alternatives available to us to unlock shareholder value. ​ Achievement of $50.0 Million TRELEGY ® Royalty Milestone Payment for 2025 In February 2026, we received a $50.0 million maximum milestone payment from Royalty Pharma Investments associated with the achievement of certain minimum royalty payments related to 2025 TRELEGY global net sales.…
