Biogen Completes $5.3 Billion Acquisition of Apellis Pharmaceuticals

Biogen has successfully completed its acquisition of Apellis Pharmaceuticals, with the transaction valued at approximately $5.3 billion. Biogen's tender offer included a cash payment of $41 per share and a contingent value right, potentially adding up to $4 based on specific sales milestones. Approximately 82.4% of Apellis' outstanding shares were tendered in the offer, leading to the merger where Apellis became a wholly owned subsidiary of Biogen.

The acquisition is expected to enhance Biogen's revenue and earnings per share growth potential, with contributions from Apellis' commercialized products, EMPAVELI® and SYFOVRE®. These products generated $689 million in net revenue in 2025 and will help Biogen expand into nephrology. The company plans to update its financial guidance in July alongside its Q2 earnings report, reflecting the anticipated benefits of this acquisition.
