“We are excited to announce the completion of Pharmacosmos’ acquisition of G1. This acquisition fits perfectly with our strategy and positions our company for the next phase of growth. We are particularly thrilled to expand our product portfolio with Cosela, an innovative first-in-class product that is making a real difference for patients with small cell lung cancer. Our focus will now be on bringing Cosela to more patients and customers in the US, where it is already approved, and to start the work to have it registered and made available internationally including in the UK and EU,” said Tobias S Christensen - CEO and President of Pharmacosmos A/S.

The tender offer commenced on August 20, 2024 and expired one minute after 11:59 p.m. Eastern Time on September 17, 2024 (the "Expiration Date"). As of the Expiration Date, a total of 39,486,447 shares of G1 Therapeutics common stock were validly tendered, and not validly withdrawn, representing approximately 74.64% of the outstanding shares of G1 Therapeutics common stock as of the Expiration Date. As of the Expiration Date, the number of shares validly tendered in accordance with the terms of the tender offer and not validly withdrawn satisfied the minimum tender condition, and all other conditions to the tender offer were satisfied. On September 18, 2024, Genesis Merger Sub, Inc., an indirect wholly owned subsidiary of Pharmacosmos A/S (“Purchaser”), irrevocably accepted for payment all shares validly tendered and not validly withdrawn and has paid the depositary for such shares.

Following the closing of the tender offer, on September 18, 2024 Purchaser merged with and into G1 Therapeutics, with G1 Therapeutics continuing as the surviving corporation and a wholly owned subsidiary of Pharmacosmos Therapeutics Inc., a U.S. subsidiary of Pharmacosmos A/S.

As a result of the transaction, G1 Therapeutics shares ceased to be traded on NASDAQ as of the date of closing of the acquisition, and shares of G1 Therapeutics common stock will be delisted from NASDAQ and deregistered under the Securities Exchange Act of 1934, as amended.

“Since our founding in 2008, G1 has been committed to improving the lives of patients living with cancer; this effort culminated in the approval and launch of COSELA^® (trilaciclib), the first and only therapy that proactively delivers multilineage myeloprotection to patients with extensive-stage small cell lung cancer being treated with chemotherapy,” said Jack Bailey, Chief Executive Officer at G1 Therapeutics. “The closing of this transaction is an exciting moment for everyone working in G1 and Pharmcosmos, and the patients we seek to treat, as the combined team moves forward with COSELA to meet the needs of even more cancer patients. Finally, I want to thank the members of the G1 team throughout these last 16 years that made this innovation possible.”
