Apellis (APLS) HSR waiting period expired; $41.00 cash plus up to $4.00 CVR

Apellis Pharmaceuticals has announced that the Hart-Scott-Rodino (HSR) waiting period for its tender offer and merger has expired as of May 11, 2026, satisfying a key regulatory condition. This paves the way for the acquisition by a Biogen subsidiary, which proposes $41.00 per share in cash plus a non-transferable contingent value right (CVR) for up to $4.00 in additional cash based on milestone achievements. The expiration removes an antitrust obstacle, but final closing depends on other conditions.
