Theravance Acquisition

Theravance was acquired by Zymeworks for $929M on 28 June 2026.

The acquisition price implies a 12.4x revenue multiple on $75M of revenue.

Zymeworks Inc. acquired Theravance Biopharma, Inc. in a cash-and-contingent value right (CVR) deal announced on June 29, 2026, with shareholders receiving $17.00 per share in cash, representing an equity value of approximately $929 million USD. The CVR entitles Theravance shareholders to 80% of net proceeds from any future license, divestiture, or monetization of ampreloxetine over ten years, while Zymeworks retains 20%. The transaction is expected to close in the second half of 2026. Strategically, the acquisition diversifies Zymeworks' revenue beyond oncology by adding commercial COPD royalties from Yupelri, which generated $75 million in revenue in 2025, plus a $100 million milestone payment from Trelegy expected in Q1 2027, and an antibiotic royalty stream. The deal is financed through a $350 million non-dilutive note from OMERS Life Sciences (secured by Yupelri assets), $219 million of Zymeworks' cash, and approximately $360 million of Theravance's cash at closing, with no new Zymeworks shares issued. Theravance Biopharma, a Dublin-based respiratory drug developer, is known for Yupelri—the first and only nebulized LAMA for COPD in the U.S., protected until April 2039—and holds early-stage pipeline assets and $2.5 billion in Irish tax attributes. Zymeworks forecasts the deal to be immediately profit-making upon close.
