Purchasers subject to beneficial ownership limitations of 4.99% or 9.99% had the option to receive pre-funded warrants in lieu of shares.

Roth Capital Partners served as exclusive placement agent for both transactions. The company stated it intends to use net proceeds for working capital purposes. Aptevo has agreed to file a registration statement with the Securities and Exchange Commission covering the resale of shares issued in connection with these transactions.
