Roche to acquire Poseida Therapeutics for USD 1.5 billion
Basel: Roche has announced that it has entered into a definitive merger agreement to acquire Poseida Therapeutics, Inc., a public clinical-stage biopharmaceutical company pioneering donor-derived CAR-T cell therapies.
Based in San Diego, California, Poseida’s R&D portfolio includes pre-clinical and clinical-stage off-the-shelf (also referred to as allogeneic) CAR-T therapies across several therapeutic areas including haematological malignancies, solid tumours, and autoimmune disease, as well as manufacturing capabilities and technology platforms.
The acquisition builds on the existing partnership between Roche and Poseida following the collaboration and licence agreement established in 2022, which focuses on developing off-the-shelf CAR-T cell therapies to address medical needs of patients with haematological malignancies.
“This exciting acquisition will allow us to drive further progress in allogeneic cell therapy while leveraging the successful existing partnership with Poseida,” said Levi Garraway, Head of Product Development and Chief Medical Officer at Roche. “We are very encouraged by the early clinical data, and this acquisition builds on our joint progress to catalyse the development of potentially first and best-in-class cell therapies in oncology, immunology and neurology.”
Under the terms of the merger agreement, Roche will promptly commence a tender offer to acquire all of the outstanding shares of Poseida common stock at a price of US $9.00 per share in cash at closing plus a non-tradeable CVR to receive certain milestone payments of up to an aggregate of US $4.00 per share in cash, representing a total equity value of approximately US $1.0 billion at closing and representing a total deal value of up to US $1.5 billion. The price payable at closing represents a premium of approximately 215% to Poseida’s closing share price on 25 November 2024. The merger agreement has been unanimously approved by the boards of Roche and Poseida.
Poseida will file a recommendation statement containing the unanimous recommendation of the Poseida board that Poseida’s stockholders tender their shares pursuant to the tender offer. Following the completion of the tender offer, Roche will acquire all remaining shares at the same price of US $9.00 per share in cash through a second step merger.
Each non-tradeable CVR will entitle its holders to receive the following contingent cash payments, conditioned upon the achievement of certain clinical development and commercial milestones, within specified time periods:
US $2.00 per share in cash, upon the initiation of the first pivotal study of a P-BCMA-ALLO1 product for the treatment of any indication (by December 31, 2028)
US $1.00 per share in cash, upon the initiation of the first pivotal study of a P-CD19CD20-ALLO1 product or of a P-BCMACD19-ALLO1 product for the treatment of an autoimmune indication (by December 31, 2034)
US $1.00 per share in cash, upon the first commercial sale of a P-BCMA-ALLO1 product for the treatment of any indication (by December 31, 2031)
There can be no assurance that any payments will be made with respect to the CVR. Assuming the conditions of the CVR are met, this would represent an additional cash consideration of up to approximately US $0.5 billion for Poseida’s stockholders.
The transaction is expected to close in the first quarter of 2025 and is subject to customary closing conditions, including the tender of at least a majority of the outstanding shares of Poseida’s common stock and the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
