Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On February 16, 2023, Adaptimmune Therapeutics plc (the “Company” or “Adaptimmune”) announced that Kristen Hege, M.D., has been appointed to its Board of Directors (the “Board”), as an independent Non-Executive Director, and Tal Zaks, M.D., Ph.D., will be resigning from the Board. Dr. Hege’s appointment will be effective from November 1, 2023 and Dr. Zaks’ resignation from the Board and Remuneration Committee will be effective from March 31, 2023. His decision to resign was not as a result of any disagreement with the Company or its management. The Board determined that Dr. Hege is an “independent director” under Rule 5605(a)(2) of the Nasdaq Listing Rules.

On February 15, 2023, the Company entered into a letter of appointment with Dr. Hege (the “Letter of Appointment”). Under the terms of the Letter of Appointment, effective November 1, 2023, Dr. Hege will receive compensation as of the effective date of her appointment in accordance with the Company’s non-executive director remuneration policy.

On or around November 1, 2023 or such other date as the Board may determine and subject to the rules of the relevant equity plan and any applicable legal or regulatory requirements, Dr. Hege will be awarded market value options to acquire ordinary shares in the Company on the condition that, at the time of the award of such share options, Dr. Hege continues to serve as a non-executive director. In addition, effective from November 1, 2023, Dr. Hege will be eligible to receive fees for her service as a non-executive director set at the usual rate provided for in the Company’s compensation package for non-executive directors, payable monthly in arrears and subject to the deduction of applicable taxes and social security payments, or may elect to waive the fees and receive an additional grant of share options of equivalent value to the fees. All share options awarded will vest as to 25% on the first anniversary of the date they are granted and the remaining 75% will vest in monthly instalments over the following two years. The share options will have an exercise price per ordinary share of not less than one sixth of the closing trading price of the Company’s American Depositary Shares on the last business day prior to the date of grant, translated from USD to GBP.

There are no family relationships between Dr. Hege and any director or executive officer of the Company, and the Company has not entered into any transactions with Dr.Hege that are reportable pursuant to Item 404(a) of Regulation S-K. Except as described above, there are no arrangements or understandings between Dr. Hege and any other persons pursuant to which she was selected as a director.

The foregoing summary of the Appointment Letter is qualified in its entirety by reference to the complete text of the Appointment Letter, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
