(NASDAQ:CTIC) (CTI), at a price of USD 9.10 per share in cash, net to the seller thereof in cash, without interest and subject to any applicable withholding taxes.

The tender offer expired as scheduled at one minute after 11:59 p.m., Eastern Time on June 23, 2023 (12:00 midnight, Eastern Time, on June 24, 2023). As of the expiration, 110,640,230 shares of common stock of CTI had been validly tendered and not validly withdrawn, representing approximately 83.8 percent of CTI's outstanding shares of common stock, according to the depositary for the tender offer. 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. At the effective time of the merger, and subject to any perfected appraisal rights, all of the remaining shares of common stock of CTI not purchased in the tender offer will be converted into the right to receive the same USD 9.10 per share, net to the seller thereof in cash, without interest and subject to any applicable withholding taxes. Upon completion of the merger, CTI will become an indirect wholly owned subsidiary of Sobi, and the common stock of CTI will cease to be traded on the NASDAQ Stock Market.

On 26 June, 2023, Sobi intends to file with the U.S. Securities and Exchange Commission (SEC) an amendment to the tender offer statement on Schedule TO which sets forth the final results of the tender offer.
