    Did Biohaven’s Kv7 Deal With SK Biopharmaceuticals Just Reshape BHVN’s Risk And Funding Profile?

    Listen to the news
    • In August 2026, Biohaven Ltd. announced a global licensing and collaboration agreement granting SK Biopharmaceuticals an exclusive worldwide license to its Kv7 ion channel platform, led by opakalim (BHV-7000), with Biohaven set to receive up to US$795 million in upfront and milestone payments plus tiered royalties on U.S. net sales.
    • The deal not only brings Biohaven US$400 million in near-term cash and up to US$150 million in additional milestones, but also shifts substantial future Kv7 development and milestone obligations, including up to US$245 million in program costs, to SK Biopharmaceuticals, reshaping Biohaven’s risk and funding profile.
    • Next, we’ll examine how offloading future Kv7 development costs to SK Biopharmaceuticals influences Biohaven’s investment narrative and capital allocation flexibility.

    What Is Biohaven's Investment Narrative?

    To own Biohaven today, you really have to believe its early science can eventually justify heavy, ongoing losses, despite zero revenue and a very large negative return on equity. The SK Biopharmaceuticals deal matters here: shifting up to US$245 million of future Kv7 costs off Biohaven’s books and bringing in US$400 million of near-term cash should ease the previous concern about a short cash runway and soften the near-term need for fresh equity. At the same time, it moves one of Biohaven’s nearer-term epilepsy catalysts partly outside the company, refocusing attention on its degraders (BHV-1300, BHV-1400) and other pipeline assets as the key value drivers. Given the volatile share price, persistent losses and shareholder dilution, the risk side of the story still feels very real.

    However, shorter cash runway concerns may not be fully resolved by this deal. Biohaven's shares have been on the rise but are still potentially undervalued. Find out how large the opportunity might be.
