Zymeworks Announces Updated 2026 Financial Guidance and Final Transaction Details Following Theravance Biopharma Acquisition

$ZYMEPress releaseSep 28, 2026, 6:00 AM ETRead the release

Zymeworks closed its acquisition of Theravance Biopharma, adding YUPELRI (revefenacin) with a 35% share of U.S. net profits via the Viatris collaboration, and Theravance shareholders received $17.00 per share in cash. Updated 2026 guidance calls for total revenue of $278-292 million and adjusted EBITDA of $114-128 million, with YUPELRI delivering $133.1 million in first-half sales and 25% Q2 hospital-sales growth. The $350 million OMERS non-recourse note keeps the deal non-dilutive, with 75% of YUPELRI profit-share cash flows servicing the debt until repayment; a potential $100 million TRELEGY milestone in Q1 2027 could offset the cash outlay.
