Apellis Soars 140% on $5.6 Billion Biogen Acquisition to Expand Rare Disease Portfolio
summarizeSummary
Biogen has agreed to acquire Apellis Pharmaceuticals for approximately $5.6 billion in cash, offering $41 per share plus potential contingent value rights of up to $4 per share tied to global sales milestones for Apellis' eye disorder drug Syfovre. This represents a substantial 140% premium to Apellis' last closing price, causing its shares to more than double in premarket trading. For Apellis, this is a definitive exit with a significant payout for shareholders. For Biogen, this acquisition materially expands its rare disease portfolio, building on recent positive developments such as a new license agreement, positive Phase 2 study results, and an FDA approval for Spinraza, indicating a strategic push for pipeline growth. Investors will now watch for the deal's completion and the successful integration of Apellis' assets, particularly the commercial performance of Syfovre.
