Item 1.02 Termination of Material Definitive Agreement.

On April 10, 2024, Adaptimmune Limited, a wholly-owned subsidiary of Adaptimmune Therapeutics plc (“Adaptimmune”) received notice of termination of the Strategic Collaboration and License Agreement with Genentech, Inc. (“Genentech”) and F. Hoffman-La Roche Ltd. (the “Agreement”). The termination will become effective 180 days after the date of receipt of the notice of termination (the “Termination Date”).

Under the Agreement, Genentech and Adaptimmune (each, a “party” and together, the “parties”) collaborated to develop two types of allogeneic T-cell therapies: (i) off-the-shelf αβ T-cell therapies directed to up to five collaboration targets and (ii) personalized therapies utilizing αβ T-cell receptors (TCRs) isolated from a patient, with these therapies being administered to the same patient. Under the terms of the Agreement, Adaptimmune received $150 million in upfront payments and $35 million in milestone payments. Until the Termination Date, the obligations of the parties under the Agreement will continue as currently provided.

As a result of the termination of the Agreement, Adaptimmune will not be entitled to receive any further milestones or other payments due after the Termination Date. Adaptimmune will also cease to have any development obligations after the Termination Date and the licenses Adaptimmune granted to Genentech pursuant to the Agreement will cease to be in effect as of the Termination Date.

The foregoing description of the termination of the Agreement is only a summary of the material terms thereof, and does not purport to be complete. The description is qualified in its entirety by reference to the Agreement, which was filed as Exhibit 10.1 to Adaptimmune’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 4, 2021 and is attached as Exhibit 10.1 hereto and incorporated herein by reference.
