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

On July 16, 2024, Adaptimmune Therapeutics plc (the “Company”) adopted an amended and restated executive severance policy effective as of July 16, 2024 (the “Updated 2024 Executive Severance Policy”). The Updated 2024 Executive Severance Policy incorporates updates to the executive severance policy established by the Company on March 10, 2017 (the “2017 Executive Severance Policy”) and amended and restated on June 11, 2024. The Updated 2024 Executive Severance Policy is applicable in relation to our executive officers and provides for post-employment compensation arrangements upon a termination of employment in certain circumstances as described below.

Under the terms of the Updated 2024 Executive Severance Policy, if the employment of any of our executive officers is terminated by the Company without cause, or if the executive officer resigns for good reason, then the executive officer will be entitled under the executive officer’s employment or service agreement, as applicable, and the Updated 2024 Executive Severance Policy to receive a severance payment equal to the executive officer’s annual base salary for 12 months and to payment of premiums for continuation of healthcare benefits for a period of 12 months following such termination (formerly, nine months under the 2017 Executive Severance Policy). Our executive officers resident in the U.K. may elect to waive continuation of payment of healthcare premiums and accept a payment in lieu of such premiums. In addition, at the sole discretion of the Company’s board of directors (or an authorized committee thereof), the executive officer may be paid a lump sum cash amount equal to his or her annual performance bonus for the year of termination, prorated based on the number of calendar days the executive officer was employed during the year of termination.

Furthermore, if the employment of any of our executive officers (other than our chief executive officer) is terminated without cause or if any of our executive officers (other than our chief executive officer) resigns for good reason within 12 months following a change in control, the executive officer will be entitled to receive a severance payment equal to the executive officer’s annual base salary for 12 months and to payment of premiums for continuation of healthcare benefits for a period of 12 months following such termination (no change compared to the 2017 Executive Severance Policy). Our executive officers resident in the U.K. may elect to waive continuation of payment of healthcare premiums and accept a payment in lieu of such premiums. In addition, the executive officer will be paid a lump sum cash amount equal to a 12 month bonus for the year of termination calculated based on the target bonus for the year of termination (formerly, the actual bonus under the 2017 Executive Severance Policy), and is entitled to accelerated vesting of any unvested and outstanding share options or other equity awards.

If the employment of our chief executive officer is terminated without cause or the chief executive officer resigns for good reason within 12 months following a change in control, the chief executive officer will be entitled to receive a severance payment equal to the chief executive officer’s annual base salary for 18 months and to payment of premiums for continuation of healthcare benefits for a period of 18 months following such termination (formerly, 12 months under the 2017 Executive Severance Policy). A chief executive officer resident in the U.K. may elect to waive continuation of payment of healthcare premiums and accept a payment in lieu of such premiums. In addition, the chief executive officer will be paid a lump sum cash amount equal to an 18 month bonus for the year of termination calculated based on the target bonus for the year of termination (formerly, the actual bonus under the 2017 Executive Severance Policy), and is entitled to accelerated vesting of any unvested and outstanding share options or other equity awards. In addition, the Company’s board of directors has discretion under our option plan rules to allow some or all of the options held by our executive officers, including the chief executive officer,to vest in the event of a change of control or otherwise.

In order to receive severance benefits under the executive officer’s employment or service agreement and the Updated 2024 Executive Severance Policy, the executive officer is required to execute a release of claims in favor of the Company and comply with certain other post-employment covenants set forth in the executive officer’s employment or service agreement, as applicable.

The foregoing summary of the Updated 2024 Executive Severance Policy is qualified in its entirety by reference to the complete text of the Updated 2024 Executive Severance Policy, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

AMENDED AND RESTATED

EXECUTIVE SEVERANCE POLICY

This Executive Severance Policy (“Policy”) has been established by Adaptimmune Therapeutics plc (the “Company”) on March 10, 2017, as amended and restated effective from June 11, 2024 and then on July 16, 2024 to provide Executives with the opportunity to receive severance benefits following termination of employment under certain conditions. The purpose of the Policy is to attract and retain qualified executives. This Policy is applicable to all Executives regardless of base location. This Policy is intended to be a top hat welfare benefit plan under the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”), maintained for a select group of management or highly compensated employees.

1.Notice of Termination; Company’s Obligations Upon Cessation of Employment Period.

(a)Notice of Termination. Notice of termination will be provided in accordance with the terms of the relevant Executive’s Employment Agreement.

(b)Company’s Obligations Upon Cessation of the Employment Period.

(i)Accrued Benefits. Unless stated otherwise, where terms of this Policy are inconsistent to the terms of Executive’s Employment Agreement, the terms of Executive’s Employment Agreement shall prevail. Subject to Executive’s Employment Agreement, upon Executive’s termination of employment for any reason and save as explicitly otherwise provided in Executive’s Employment Agreement, Executive shall be entitled to receive: (A) Base Salary (as defined in Executive’s Employment Agreement) earned for services rendered by Executive through the date of termination, which shall be paid on the next succeeding payroll date unless otherwise mutually agreed; (B) payment of any accrued but unused vacation as of the date of termination owed to Executive as provided for under Executive’s Employment Agreement; (C) any unpaid expense reimbursement owed to Executive under Executive’s Employment Agreement, which shall be paid within thirty (30) days of the date of termination; and (D) any amount earned, accrued and arising from Executive’s participation in, or benefits accrued under, any Company employee benefit plan or arrangement, which amounts shall be payable in accordance with the terms and conditions of such employee benefit plans and arrangements (collectively, the “Accrued Benefits”).

(ii)Termination by Company Without Cause or by Executive For Good Reason; No Change in Control. If the Employment Period is terminated by the Company without Cause or if Executive resigns for Good Reason other than in the twelve (12) months following the date of a Change in Control, in addition to the Accrued Benefits, Executive shall be entitled to receive: (A) an amount equal to his or her Base Salary (as in effect immediately prior to termination of employment) for a period of twelve (12) months following the date of termination, paid in a single lump sum as soon as administratively feasible within sixty (60) days following the date of termination; (B) any unpaid Annual Bonus (as defined in Executive’s Employment Agreement) relating to the year prior to the year in which the date of termination of employment occurs, paid in a single lump sum no later than March 15 of the year following the calendar year in which the Annual Bonus, if any, was earned; (C) at the discretion of the Board of Directors of the Company (the “Board”) a prorated amount of any Annual Bonus relating to the year in which the date of termination of employment occurs, based on the number of full calendar months worked by Executive during such year divided by twelve (12), and paid in a single lump sum no later than March 15 of the year following the calendar year in which the prorated Annual Bonus, if any, was earned; and (D) either (a) reimbursement of Executive’s payment of the full monthly premiums required for Executive’s continued participation in the Company’s group health coverage shall be pursuant to the U.S. Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), through the end of the twelfth (12th) month following the date of termination, provided that Executive is eligible for and timely elects to receive COBRA coverage and that such provision of healthcare does not result in discrimination in the Company’s healthcare plan in which Executive participates under Section 105(h) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated thereunder or (b) where COBRA does not apply to Executive, continuation of the health coverage provided under Executive's Employment Agreement through the end of the twelfth (12th) month following the date of termination provided such continuation is permitted under the terms of the relevant insurance, or (at the election of a UK Executive) payment of the cash equivalent of the cost to the Company of providing such health coverage during such period. The benefits identified under Section 1(b)(ii)(A) to (D) are collectively referred to as “Severance Benefits”). The payment of Base Salary under Section 1(b)(ii)(A) and any payment in respect of health coverage under Section 1(b)(ii)(D) shall be reduced by any Base Salary or health coverage payments otherwise made to Executive by way of a payment in lieu of notice under Executive's Employment Agreement.

The Company may offset any amounts Executive owes the Company or its affiliates or subsidiaries against any amounts the Company owes Executive hereunder subject to applicable law.

(viii)The Company’s obligation to provide the Severance Benefits to Executive or CIC Severance Benefits to Executive (excluding Chief Executive Officer) or CEO CIC Severance Benefits to Chief Executive Officer shall be conditioned upon Executive’s execution and the irrevocability of a general release in a form acceptable to the Company within 60 days following termination of employment.

(C)

"termination,” and “termination of employment” shall mean a “separation from service” as defined in Section 409A. If any amount that constitutes deferred compensation for purposes of Section 409A is to be paid in two or more installments, each installment shall constitute a separate payment; and

(D)

4.Miscellaneous.

(a)Administration. The Administrator has the exclusive right, power and authority, in its sole and absolute discretion, to administer and interpret the Policy. The Administrator has all powers reasonably necessary to carry out its responsibilities under the Policy. The decision of the Administrator on any disputes arising under the Policy, including (but not limited to) questions of construction, interpretation and administration shall be final, conclusive and binding on all persons having an interest in or under the Policy. For the avoidance of doubt, the role of the Administrator is limited to the administration of this Policy and, as such, it is acknowledged that determinations by the Administrator are not final or binding with respect to any subsequent dispute resolution process and shall not be afforded a special status during any legal action.

(b)Amendment and Termination. The Company reserves the right to amend or terminate the Policy at any time by action of the Board. However, the Company shall consult with Executive in relation to any proposed significant amendment or termination. Where any proposed amendment or termination of this Policy substantially reduces the rights or benefits of Executive, then such amendment or termination will only take effect if made in accordance with the terms of Executive’s Employment Agreement.

(c)At-Will Employment. The Policy does not alter the status of each Executive, for Executives based in the US such Executives are employed as an at-will employee of the Company. Nothing contained herein shall be deemed to give any Executive the right to remain employed by the Company or to interfere with the rights of the Company to terminate the employment of any Executive at any time, with or without Cause.

(d)Unfunded Obligations. The amounts to be paid to Executives under the Policy are unfunded obligations of the Company. The Company is not required to segregate any monies or other assets from its general funds with respect to these obligations. Executives shall not have any preference or security interest in any assets of the Company other than as a general unsecured creditor.

(e)Transfer and Assignment. Neither an Executive nor any other person shall have any right to sell, assign, transfer, pledge, anticipate or otherwise encumber, transfer, hypothecate or convey any amounts payable under the Policy prior to the date that such amounts are paid.

(f)References to the Company. Where the employing company of the Executive is not the Company but another member of the Company's group, references in this Policy to the Company shall be construed accordingly and, where necessary, shall be deemed to be or include references to the relevant employing company.

(iii)Executive has the right to be provided with, upon request and free of charge, reasonable access to and copies of all pertinent documents, records and other information that is relevant to his or her claim for benefits.

(iv)The review of the denied claim will take into account all comments, documents, records and other information that Executive submitted relating to his or her claim, without regard to whether such information was submitted or considered in the initial denial of his or her claim.

(h)Administrator's Response to Appeal. The Administrator will provide Executive with written notice of its decision within 30 days after the Administrator’s receipt of Executive’s written claim for review. The Administrator’s decision on Executive’s claim for review will be communicated to Executive in writing and will clearly state:

(i)Exhaustion of Administrative Remedies. The exhaustion of these claims procedures is mandatory for resolving every claim and dispute arising under the Policy.
