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") was issued under the Talen Energy Corporation 2023 Equity Incentive Plan (the "Plan") and represents a contingent right to receive one share of common stock, par value $0.001 ("common stock") of Talen Energy Corporation (the "Company") or its cash equivalent, as determined at the time of settlement by the Compensation Committee of the Company's Board of Directors (the "Committee") pursuant to the terms of the Plan. The reporting person's RSUs were granted on June 16, 2023 and the final installment of the reporting person's RSUs vested on May 17, 2026, the third anniversary of the vesting commencement date, with 60% of the after-tax value of such RSUs settled in cash.
(2)	Each performance-based restricted stock unit ("PSU") was issued under the Plan and represents a contingent right to receive one share of common stock or its cash equivalent, as determined at the time of settlement by the Committee pursuant to the terms of the Plan. The number of PSUs that vest can range from 0% to 200% of the target number of PSUs subject to the award, plus an additional incentive based on the Company's market capitalization at vesting, as more fully set forth in the applicable award agreement. The number of shares in this row represents the actual level of performance (200%) plus the additional incentive shares described above. The reporting person's PSUs were granted on June 16, 2023 and they vested on May 17, 2026, the third anniversary of the vesting commencement date, with 60% of the after-tax value of such PSUs settled in cash.
(3)	In an exempt disposition to the Company under Rule 16b-3(e), the reporting person remitted shares to the Company in connection with the satisfaction of tax withholding obligations arising out of the vesting of the RSUs and PSUs.
