NEW HAVEN, Conn., Sept. 18, 2022 /PRNewswire/ -- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN) ("Biohaven") today announced that it has set a record date of September 26, 2022 (the "Record Date") for the previously announced spin-off by Biohaven of its Biohaven Ltd. ("SpinCo") subsidiary, which will own the Kv7 ion channel activators, glutamate modulation, myeloperoxidase inhibition and myostatin inhibition platforms, preclinical product candidates, and certain corporate infrastructure currently owned by Biohaven. The completion of the spin-off remains subject to closing conditions noted in Biohaven's Proxy Statement filed on August 30, 2022, including receipt of shareholder approval at Biohaven's special meeting of shareholders to be held on September 29, 2022.

Beginning on September 23, 2022, and continuing until the occurrence of the distribution on the Distribution Date, Biohaven common shares will trade with an entitlement to the distribution under the symbol "BHVN". Any holders of Biohaven common shares who sell shares on or before the Distribution Date will also be selling their right to receive SpinCo common shares. Investors are encouraged to consult with their financial advisors regarding the specific implications of buying or selling Biohaven common shares on or before the Distribution Date.

Beginning on September 23, 2022, SpinCo common shares are expected to begin trading on a "when-issued" basis on the New York Stock Exchange under the symbol "BHVN WI" and under "Biohaven Ltd." When-issued trading of SpinCo common shares will continue until the distribution occurs.
