| F1 | These securities are time-based restricted stock units, each representing a contingent right to receive one share of common stock, par value $0.10 per share, of FirstEnergy Corp. (the "Company"). The time-based restricted stock units were granted under the Company's 2020 Incentive Compensation Plan and will vest in full on March 1, 2029. |
| F2 | Represents the vesting of performance-adjusted restricted stock units ("RSUs"), each of which previously represented a contingent right to receive an RSU award payable 2/3 in shares of common stock of the Company ("Share-Based RSUs") and 1/3 in cash ("Cash-Based RSUs") following the vesting date. The satisfaction of the performance goals for the RSUs were certified by the Company's Board of Directors on February 11, 2026, as previously reported on a Form 4 filed on February 13, 2026, and the RSUs, which had remained subject to a continued service requirement, vested on March 1, 2026. |
| F3 | The RSUs converted into shares of the Company's common stock on a one-for-one basis under the Company 2020 Incentive Compensation Plan. |
| F4 | Represents shares of common stock of the Company withheld to cover tax obligations associated with the vesting on March 1, 2026, of the Share-Based RSUs described in footnote 2, which transaction is exempt under Rule 16b-3. |
| F5 | On March 1, 2026, the Cash-Based RSUs were settled based on an average of the Company's high and low stock price on February 27, 2026, net of applicable tax withholding obligations. |
| F6 | 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 February 28, 2026. |
| F7 | RSUs convert into the Company's common stock on a one-for-one basis. |
