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)	Balance has been updated since the reporting person's last filed Form 4 to include shares acquired through dividend reinvestments.
(2)	The Company's 401(k) Savings Plan includes a unitized fund invested in shares of common stock of the Company, in which the reporting person may invest, and includes dividend reinvestment and company match features. The number of shares reported as indirectly held in the 401(K) Savings Plan in this row is an estimate of the number of shares of the Company's common stock held in the unitized stock fund since the reporting person's last filed Form 4 and as allocated to the reporting person's account as of January 31, 2025.
(3)	Represents performance-adjusted restricted stock units ("RSUs"), each of which represents a contingent right to receive an award payable 2/3 in Company common stock and 1/3 in cash following the vesting date. This Form 4 is being filed to report the satisfaction of the performance goals for the RSUs, as certified by the Company's Board of Directors on February 5, 2025. As a result, these RSUs will vest on March 1, 2025, generally subject to the reporting person's continued service.
(4)	Each share of phantom stock is the economic equivalent of one share of common stock. This holding reflects phantom stock payable in cash upon retirement or other termination of employment under the FirstEnergy Corp. Amended and Restated Executive Deferred Compensation Plan.
(5)	Includes phantom stock acquired through dividend reinvestments.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
