Footnotes

F1: These securities are restricted stock units ("RSUs"), each representing a contingent right to receive one share of common stock, par value $0.10 per share, of FirstEnergy Corp. (the "Company"). The RSUs were granted under the Company's 2020 Incentive Compensation Plan and will vest in full on March 1, 2028. This transaction is being reported late due to an inadvertent administrative error and not any error of the Reporting Person.

F2: Balance includes dividends accrued on time-based equity awards.

F3: This Form 4 is being filed to report the number of shares withheld to satisfy the reporting person's tax withholding obligation upon the vesting of 36,630 shares of restricted common stock granted pursuant to the terms of the Restricted Stock Award Agreement, dated June 1, 2023, between the Company and the reporting person.

F4: The Company's 401(k) Savings Plan ("401(k) 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) 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 May 31, 2025.
