Poseida Therapeutics to Be Acquired by Roche in $1.5 Billion Deal

Key Points:
– Poseida Therapeutics to be acquired by Roche for up to $1.5 billion, advancing the field of allogeneic CAR-T therapies.
– Poseida’s non-viral, TSCM-rich CAR-T therapies aim to enhance clinical outcomes and expand treatment access.
– Roche’s capabilities in late-stage development and commercialization will bring Poseida’s advancements to patients worldwide.

Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage biopharmaceutical company pioneering allogeneic cell and genetic therapies, announced that it has entered into a definitive agreement to be acquired by Roche Holdings, Inc. in a transaction valued at up to $1.5 billion. Under the agreement, Poseida stockholders will receive $9.00 per share in cash upon closing, along with a contingent value right (CVR) for up to $4.00 per share upon achieving specified milestones. The acquisition has been unanimously approved by Poseida’s Board of Directors, which recommends that stockholders tender their shares.

The merger will bring Poseida’s advanced platform technologies and innovative therapies into Roche’s Pharmaceuticals Division. This acquisition marks a significant expansion of Roche’s capabilities in allogeneic cell therapy, a cutting-edge area of biotech innovation focused on creating “off-the-shelf” treatments. This collaboration builds on an ongoing strategic partnership between Poseida and Roche, particularly in developing CAR-T therapies for hematologic malignancies. The expanded scope will also include CAR-T programs targeting solid tumors and autoimmune diseases.

Poseida’s proprietary technology platform, which utilizes non-viral, T stem cell memory (TSCM)-rich CAR-T therapies, is at the forefront of innovation in cell therapy. TSCM cells are considered highly advantageous due to their long-lived, self-renewing, and multipotent properties, enabling potentially safer and more effective therapies. These characteristics differentiate Poseida’s therapies from other CAR-T approaches, which often rely on more differentiated cells with reduced regenerative capacity.

Highlighting Poseida’s potential, interim clinical data for P-BCMA-ALLO1, a CAR-T candidate for multiple myeloma, have shown compelling results. This reinforces the transformative potential of Poseida’s platform in addressing high unmet needs across various therapeutic areas. Kristin Yarema, Ph.D., President and CEO of Poseida Therapeutics, emphasized the importance of the acquisition:
“Poseida has demonstrated the unique ability of its non-viral platform to deliver TSCM-rich CAR-T therapies with the potential to improve clinical outcomes and expand access. Joining Roche will allow us to accelerate development and bring our therapies to patients worldwide.”

The transaction terms include a tender offer for all outstanding Poseida shares, priced at $9.00 per share in cash at closing. The CVR, valued at up to $4.00 per share, will be contingent upon achieving specific clinical, regulatory, and commercial milestones. Roche plans to acquire any remaining shares not tendered during the initial offer through a second-step merger, ensuring full ownership of Poseida.

The deal is expected to close in the first quarter of 2025, subject to regulatory approvals and customary closing conditions. Centerview Partners LLC and Cooley LLP advised Poseida on the transaction, while Citi and Sidley Austin LLP served as advisors to Roche.

This acquisition represents a major milestone for Poseida and Roche alike. For Roche, it establishes a new core capability in allogeneic cell therapy and genetic medicine, areas that hold immense promise for the future of personalized healthcare. For Poseida, the merger offers an opportunity to leverage Roche’s global resources in late-stage development, commercialization, and market access, enabling its therapies to reach patients worldwide.

As the biotech industry increasingly focuses on transformative therapies, this deal underscores the growing importance of partnerships in accelerating innovation. With Poseida’s cutting-edge technology and Roche’s global expertise, the acquisition is poised to reshape the landscape of cell and genetic therapies, delivering groundbreaking treatments to patients across the globe.
