SOUTH SAN FRANCISCO, Calif. and LOS ANGELES - Alumis Inc. (NASDAQ: ALMS) and ACELYRIN, INC. (NASDAQ: SLRN) today announced an amendment to their merger agreement terms, increasing ACELYRIN stockholders’ ownership in the combined company. The revised exchange ratio will give ACELYRIN stockholders approximately 48% ownership, while Alumis stockholders will own about 52% on a fully diluted basis.

According to the updated terms, ACELYRIN stockholders will receive 0.4814 shares of Alumis common stock for each ACELYRIN share they own. This adjustment reflects a significant increase from the original merger agreement and is seen as a move to maximize value for ACELYRIN stockholders while strengthening the combined entity.
