March 31 (Reuters) - Biogen BIIB.O has agreed to acquire Apellis Pharmaceuticals for about $5.6 billion in cash, expanding its portfolio of rare-disease medicines, the companies said on Tuesday.
Under the terms of the deal, Apellis shareholders will receive $41 per share in cash, representing a premium of about 140% to the stock's last close.
They are also eligible to receive two payments of $2 per share each, contingent on certain global sales milestones for Apellis' eye disorder drug Syfovre, the companies said.
Shares of Apellis rose more than twofold in premarket trading.
