The conditions to the tender offer were satisfied, and Sobi and Cleopatra have accepted for payment and will promptly pay the depositary for all validly tendered shares.

Sobi expects to complete the acquisition of CTI on 26 June, 2023, through a merger without a vote or meeting of CTI’s stockholders pursuant to Section 251(h) of the General Corporation Law of the State of Delaware.
