Exhibit 99.1

Theravance Biopharma Announces Approval of YUPELRI® (revefenacin) by China’s NMPA

DUBLIN, June 26, 2025 -- Theravance Biopharma, Inc. ("Theravance Biopharma" or the "Company") (NASDAQ: TBPH) today announced that Viatris Inc. (“Viatris”), has secured regulatory approval from China’s National Medical Products Administration (NMPA) for YUPELRI® (revefenacin) inhalation solution, the first once-daily nebulized long-acting muscarinic antagonist (LAMA) approved for maintenance treatment of chronic obstructive pulmonary disease (COPD) in China.

This approval triggers a one-time $7.5 million milestone from Viatris to Theravance Biopharma, which is expected to be received in Q3 2025. Theravance Biopharma is also eligible for further sales-based milestones of up to $37.5 million and tiered royalties of 14% to 20% on net sales in China. Viatris is responsible for all aspects of development and commercialization of YUPELRI in China.

Today’s announcement offers further support for Theravance Biopharma’s diversified and improving financial position, which includes $131 million in cash as of March 31, 2025, an additional $225 million from the recent sale of TRELEGY royalties to GSK, 35% of U.S. YUPELRI profits, and up to $150 million in near-term potential TRELEGY milestone payments from Royalty Pharma. It also comes as the Company nears completion of enrollment in the open label portion of CYPRESS, its registrational study of ampreloxetine in symptomatic neurogenic orthostatic hypotension associated with multiple system atrophy. Ampreloxetine is a wholly-owned asset with the potential to address a significant unmet need in this rare neurological disorder.

About Ampreloxetine

Ampreloxetine, an investigational, once-daily, selective norepinephrine reuptake inhibitor in development for the treatment of symptomatic neurogenic orthostatic hypotension (nOH) in patients with multiple system atrophy (MSA). The unique benefits of ampreloxetine treatment reported in MSA patients from Study 0170 included an increase in norepinephrine levels, a favorable impact on blood pressure, clinically meaningful and durable symptom improvement, and no signal for worsening of supine hypertension. In the US, the Company has been granted an Orphan Drug Designation for ampreloxetine for the treatment of symptomatic nOH in patients with MSA and, if results from the ongoing Phase 3 CYPRESS study are supportive, plans to file an NDA for full approval in this indication.

About CYPRESS (Study 0197), a Phase 3 Study

Study 0197 (NCT05696717) is currently enrolling. This is a registrational Phase 3, multi-center, randomized withdrawal study to evaluate the efficacy and durability of ampreloxetine in participants with MSA and symptomatic nOH after 20 weeks of treatment; the primary endpoint of the study is change in the Orthostatic Hypotension Symptom Assessment (OHSA) composite score. The Study includes four periods: screening, open label (12-week period, participants will receive a single daily 10 mg dose of ampreloxetine), randomized withdrawal (eight-week period, double-blind, placebo-controlled, participants will receive a single daily 10 mg dose of placebo or ampreloxetine), and a long-term treatment extension. Secondary outcome measures include change from baseline in Orthostatic Hypotension Daily Activity Scale (OHDAS) item 1 (activities that require standing for a short time) and item 3 (activities that require walking for a short time).
