Janus Henderson Group plc Decreases Percentage Ownership in Biohaven Ltd. to 11.7%

On May 15, 2026, Janus Henderson Group plc filed a Schedule 13G/A with the SEC, reporting a decrease in its ownership percentage of Biohaven Ltd. (BHVN). As of the event date of March 31, 2026, the firm beneficially owns 17,534,612 common shares, representing an 11.7% stake in the company. This reflects a decrease from the previously reported 12.7% ownership stake, despite an absolute increase in the number of shares held from 16,803,459 to 17,534,612, likely due to changes in the issuer's total outstanding shares. Janus Henderson Group plc serves as the ultimate parent company for various SEC-registered investment advisers, including Janus Henderson Investors US LLC and Janus Henderson Investors UK Limited. These asset managers exercise shared voting and dispositive power over the shares held within their managed portfolios. The filing confirms that the securities were acquired in the ordinary course of business and not for the purpose of influencing or changing the control of the issuer. No single managed portfolio holds more than 5% of the outstanding common shares.
