To effect the separation, Anaptys' board of directors approved a distribution to Anaptys stockholders of all shares of First Tracks Bio common stock. Holders of Anaptys common stock will be entitled to receive one share of First Tracks Bio common stock for every one share of Anaptys common stock held on the expected record date of April 6. The distribution is expected to occur on April 20, prior to market open. For U.S. federal income tax purposes, the distribution is expected to be a taxable transaction for Anaptys.
