Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Each restricted stock unit ("RSU") represents a contingent right to receive one share of common stock of MiNK Therapeutics, Inc. (the "Company").
(2)	Represents sales of shares, as a consequence of the vesting of restricted stock units, solely to satisfy tax withholding obligations incurred upon vesting.
(3)	Represents a weighted average price. The shares were sold in multiple transactions at prices ranging from $10.33 to $10.61. The reporting person undertakes to provide to the Company, any shareholder of the Company, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.
(4)	On October 11, 2023 the reporting person was granted RSUs under the Company's 2021 Equity Incentive Plan, vesting in three substantially equal annual installments on each of the third, fourth and fifth anniversaries of the grant date. This award was previously reported as covering 695,750 RSUs but was adjusted to 69,573 RSUs to reflect the 1-for-10 reverse stock split (rounding) that occurred on January 28, 2025.
