Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 10 footnotes

Footnote 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.

Footnote 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.

Footnote 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.

Footnote F4

Represents shares of common stock of the Company automatically 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.

Footnote 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.

Footnote F6

In connection with the vesting of the Share-Based RSUs on March 1, 2026, the reporting person's receipt of 13,657 shares of the Company's common stock was deferred, resulting in the reporting person receiving instead 13,657 shares of phantom stock pursuant to the Company's deferred compensation plan. The reporting person is therefore reporting the disposition of 13,657 shares of common stock in exchange for an equal number of shares of phantom stock.

Footnote F7

The Company 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 February 28, 2026.

Footnote F8

RSUs convert into the Company's common stock on a one-for-one basis.

Footnote F9

Each share of phantom stock represents a right to receive one share of the Company's common stock.

Footnote F10

The phantom stock becomes payable upon the reporting person's death, disability or termination of employment with the Company.
