THIS 2022 INTERIM CHIEF EXECUTIVE OFFICER RESTRICTED STOCK UNITS AWARD AGREEMENT (the “Agreement”), effective as of October 28, 2022 (the “Grant Date”), is entered into by and between the Company and Mr. John W. Somerhalder II (the “Grantee”).

1.Definitions. Unless otherwise specified in this Agreement, capitalized terms shall have the meanings attributed to them under the FirstEnergy Corp. 2020 Incentive Compensation Plan.

2.Grant of 2022 Interim Chief Executive Officer Restricted Stock Units Award.

(a)Description of Award. As of the Grant Date, the Company has granted to the Grantee an Award of Restricted Stock Units under the Plan effectively reflecting the right to earn payment of an amount of Shares for each calendar month (or partial calendar month), commencing with September 2022 and ending with December 2022, during which the Grantee serves without interruption in 2022 as Interim President and Chief Executive Officer of the Company. The Award described in this Agreement is collectively referred to as the “2022 Interim CEO Restricted Stock Units Award.” The 2022 Interim CEO Restricted Stock Units Award was granted in accordance with, and subject to, all the terms, conditions and restrictions of the Plan, which is hereby incorporated by reference in its entirety. The Grantee irrevocably agrees to, and accepts, the terms, conditions and restrictions of the Plan and this Agreement on the Grantee’s own behalf and on behalf of any heirs, successors and assigns.

(b)Target Restricted Stock Units; Monthly Allocation of Target Restricted Stock Units; Final Earned RSUs. In particular, under the 2022 Interim CEO Restricted Stock Units Award, the Company has granted to the Grantee the right to earn a percentage (but not more than 200%) of 53,260 (the “Target”) Restricted Stock Units (the “Restricted Stock Units” or “RSUs”), allocated as follows: (i) 7,609 Target RSUs for the period September 16, 2022 through and including September 30, 2022 (the “September Period”); (ii) 15,217 Target RSUs for the period October 1, 2022 through and including October 31, 2022 (the “October Period”); (iii) 15,217 Target RSUs for the period November 1, 2022 through and including November 30, 2022 (the “November Period”); and (iv) 15,217 Target RSUs for the period December 1, 2022 through and including December 31, 2022 (the “December Period” and, together with the October Period and the November Period, the “Monthly Periods”); but with such Target RSUs subject to adjustment as provided for in Section 3 of this Agreement to determine the final number of Restricted Stock Units earned under this Agreement for the Grantee’s service as Interim President and Chief Executive Officer of the Company from September 16, 2022 through and including January 4, 2023 (such adjustment, the “Adjustment,” and such final number of earned Restricted Stock Units, the “Final Earned RSUs”).

3.Adjustments to Determine Final Earned RSUs.

(a)Determination of Monthly Period Share Number. As of January 4, 2023, for each Monthly Period, (A) the Company shall calculate the product of (1) the quotient of (a) $600,000 divided by (b) the average of the highest and lowest closing prices for the Shares for the trading days in such Monthly Period on the New York Stock Exchange, multiplied by (2) a fraction (not greater than one) the numerator of which is the number of calendar days during such Monthly Period during which the Grantee actually served as Interim President and Chief Executive Officer of the Company, and the denominator of which is the total number of calendar days in

such Monthly Period (for each Monthly Period, rounded up to the nearest whole number, the “Monthly Period Share Number”).

(b)Determination of Adjustment for October Period. For the October Period: (A) if the October Monthly Period Share Number is less than (or equal to) the October Period Target RSUs, then, in calculating the Final Earned RSUs, the Target RSUs evidenced by this Agreement shall be reduced by the difference between (1) the October Period Target RSUs minus (2) the October Monthly Period Share Number (rounded up to the nearest whole number); or (B) if the October Monthly Period Share Number is more than the October Period Target RSUs, then, in calculating the Final Earned RSUs, the Target RSUs evidenced by this Agreement shall be increased by the difference between (1) the October Monthly Period Share Number minus (2) the October Period Target RSUs (rounded up to the nearest whole number).

(c)Determination of Adjustment for November Period. For the November Period: (A) if the November Monthly Period Share Number is less than (or equal to) the November Period Target RSUs, then, in calculating the Final Earned RSUs, the Target RSUs evidenced by this Agreement shall be reduced by the difference between (1) the November Period Target RSUs minus (2) the November Monthly Period Share Number (rounded up to the nearest whole number); or (B) if the November Monthly Period Share Number is more than the November Period Target RSUs, then, in calculating the Final Earned RSUs, the Target RSUs evidenced by this Agreement shall be increased by the difference between (1) the November Monthly Period Share Number minus (2) the November Period Target RSUs (rounded up to the nearest whole number).

(d)Determination of Adjustment for December Period. For the December Period: (A) if the December Monthly Period Share Number is less than (or equal to) the December Period Target RSUs, then, in calculating the Final Earned RSUs, the Target RSUs evidenced by this Agreement shall be reduced by the difference between (1) the December Period Target RSUs minus (2) the December Monthly Period Share Number (rounded up to the nearest whole number); or (B) if the December Monthly Period Share Number is more than the December Period Target RSUs, then, in calculating the Final Earned RSUs, the Target RSUs evidenced by this Agreement shall be increased by the difference between (1) the December Monthly Period Share Number minus (2) the December Period Target RSUs (rounded up to the nearest whole number).

(e)Determination of Final Earned RSUs. As of January 4, 2023, once the Adjustments for the October Period, November Period and December Period have been determined, the number of Final Earned RSUs subject to this Agreement shall be determined based on the Adjustments described above as applied to the Target RSUs (and in no event will the Final Earned RSUs exceed 200% of such Target RSUs). Such Final Earned RSUs shall vest and become payable, and will be paid, in accordance with the terms and conditions of the Plan and this Agreement.

4.Restrictions on 2022 Interim CEO Restricted Stock Units Award. Except as otherwise provided in this Agreement, and specifically subject to Section 7 of this Agreement, the Grantee cannot sell, transfer, assign, hypothecate or otherwise dispose of the 2022 Interim CEO Restricted Stock Units Award (or any Shares payable thereunder prior to actual payment of such Shares), or pledge the 2022 Interim CEO Restricted Stock Units Award (or any Shares payable thereunder prior to actual payment of such Shares) as collateral for a loan, other than by will or by the laws of descent and distribution, and in no event may the 2022 Interim CEO Restricted Stock Units Award (or any Shares payable thereunder prior to actual payment of such Shares) be transferred for value. In addition, the 2022 Interim CEO Restricted Stock Units Award, and any payments made with respect thereto, will be subject to such other restrictions as the Committee deems necessary or appropriate, including, without limitation, the Company’s Executive

Compensation Recoupment Policy and the Company’s Insider Trading Policy, as each may be amended from time to time, or their successors, to the extent applicable. The restrictions described in this Section 4 are referred to as the “Transfer Restrictions.” For purposes of clarification, neither the 2022 Interim CEO Restricted Stock Units Award nor any Shares paid pursuant thereto will be considered compensation for the Grantee’s service as a Nonemployee Director of the Company.

5.Vesting; Timing for Settlement.

(a)Vesting. Except as otherwise provided in Section 7 or Section 8 below, if and to the extent Final Earned RSUs are earned under this Agreement, such Final Earned RSUs will vest on January 4, 2023 (the “Vesting Date”) as long as the Grantee remains continuously employed by the Company or a Subsidiary until such Vesting Date. The Grantee will have no rights to the Shares underlying the Final Earned RSUs until the Final Earned RSUs have vested and been settled (each Final Earned RSU that vests pursuant to this Section 5 or Section 7 or Section 8 below, a “Vested RSU”). Prior to settlement, each Final Earned RSU (whether or not a Vested RSU) represents an unfunded and unsecured obligation of the Company.

(b)Settlement. Except as otherwise provided in Section 8 or Section 12 below, and subject to Section 9 of this Agreement, the Company shall settle each Vested RSU by delivering one Share per Vested RSU to the Grantee (or the Grantee’s estate) during the period from and including January 4, 2023, to January 31, 2023. Fractional Vested RSUs, if any, will be settled in cash.

6.Forfeiture. Except as otherwise provided in Section 7 and Section 8, the Grantee will forfeit the Grantee’s interest in the RSUs evidenced by this Agreement to the extent reduced pursuant to the Adjustment, and/or if the Company terminates the Grantee’s employment with the Company and its Subsidiaries for Cause prior to the Vesting Date, and/or if the Grantee voluntarily terminates the Grantee’s employment with the Company and its Subsidiaries prior to the Vesting Date.

7.Alternative Vesting Situations. Notwithstanding any provision in this Agreement to the contrary:

(a)Commencement of Employment of Successor Chief Executive Officer Prior to Vesting Date. If, after the Grant Date but prior to the Vesting Date, and at a time when the RSUs evidenced by this Agreement have not been forfeited, the Grantee ceases to serve as Interim President and Chief Executive Officer of the Company because a person other than the Grantee commences employment with the Company in the role of the Company’s Chief Executive Officer (as appointed by the Board) to be the successor to the Grantee, then the Final Earned RSUs shall become Vested RSUs on the Vesting Date (and Grantee’s continued employment with the Company or a Subsidiary until the Vesting Date will no longer be required).

(b)Death, Involuntary Termination of Employment Due to Disability, or Involuntary Termination of Employment Without Cause. If, after the Grant Date but prior to the Vesting Date, and at a time when the RSUs evidenced by this Agreement have not been forfeited, (i) the Grantee dies, (ii) the Grantee’s employment with the Company and its Subsidiaries is involuntarily terminated due to the Grantee’s Disability, or (iii) the Grantee’s employment with the Company and its Subsidiaries is involuntarily terminated by the Company without Cause, then, subject to Section 7(c) below, the Final Earned RSUs shall become Vested RSUs on the Vesting Date (and Grantee’s continued employment with the Company or a Subsidiary until the Vesting Date will no longer be required).

(c)Release Requirement. Notwithstanding any provision in this Agreement to the contrary, except as otherwise determined by the Company, in order for the Grantee to receive Shares pursuant to the settlement of Vested RSUs under Section 7(b) above, the Grantee (or the representative of his or her estate) must execute and deliver to the Company a general release and waiver of claims against the Company, its Subsidiaries and their directors, officers, employees, shareholders and other affiliates in a form that is satisfactory to the Company (the “Release”). The Release must become effective and irrevocable under applicable law no later than 30 days following the date of the Grantee’s death or termination of employment, as applicable.

8.Change in Control. If, after the Grant Date but prior to the Vesting Date, and at a time when the RSUs evidenced by this Agreement have not been forfeited, a Change in Control occurs, the RSUs shall generally become subject to the terms and conditions of Article 16 of the Plan; provided, that if the RSUs evidenced by this Agreement are not otherwise assumed, replaced or continued in connection with the Change in Control in the form of a Replacement Award, then notwithstanding Section 5(b) of this Agreement, the Company (or its successor in the Change in Control) shall determine the Final Earned RSUs as of a reasonable date immediately preceding the Change in Control, and such Final Earned RSUs shall become Vested RSUs and shall be settled as of the date of, and immediately prior to, the Change in Control (and Grantee’s continued employment with the Company or a Subsidiary until the Vesting Date will no longer be required).

10.Dividend Equivalents. Until the date on which the RSUs are settled for Shares or forfeited, and pursuant to the terms and conditions of this Agreement, the Grantee will be credited (in the manner described in the following sentences) on the books and records of the Company with an amount per each RSU equal to the amount per share of any cash dividends declared by the Board of Directors of the Company with a record date on or after the Grant Date on the outstanding Shares (such amount, a “Dividend Equivalent”). Such Dividend Equivalents will be credited in the form of an additional number of RSUs, and the Target RSUs shall be adjusted by each additional RSU credited to the Grantee pursuant to the Dividend Equivalents. The additional number of RSUs will be equal to the aggregate amount of Dividend Equivalents credited under this Agreement on the respective dividend payment date divided by the average of the high and low prices per Share on the respective dividend payment date. The RSUs attributable to the Dividend Equivalents will be either settled or forfeited, as appropriate, under the same terms and conditions that apply to the other RSUs under this Award Agreement, including the Adjustment and any action taken by the Committee.

11.Continuous Employment. So long as the Grantee continues to be an employee of the Company or any of its Subsidiaries, the Grantee shall not be considered to have experienced a termination of employment because of: (a) any temporary leave of absence approved in writing by the Company or such Subsidiary; or (b) any change of duties or position (including transfer from one Subsidiary to another).

12.Withholding. Notwithstanding any other provision of the Plan or this Agreement to the contrary, unless the Committee determines otherwise, the Company shall withhold Shares in an amount not to exceed the maximum amount necessary to satisfy all federal, state, local, or other taxes to be withheld in connection with the settlement of Vested RSUs or any other applicable taxable event under this Agreement.

13.No Shareholder Rights Until Payment. The Grantee shall have no shareholder rights (or rights as a beneficial owner), including no voting rights, with respect to the RSUs or any Share underlying the RSUs unless and until the Grantee receives such Share upon settlement of the RSUs.

14.Recoupment. This Agreement will be administered in compliance with Section 10D of the Exchange Act, any applicable rules or regulations promulgated by the Securities and Exchange Commission or any national securities exchange or national securities association on which the Shares may be traded, and will be subject to the Company’s Executive Compensation Recoupment Policy, as amended from time to time, or any other successor Company policy, including those adopted pursuant to applicable law, rules, or regulations (and this Agreement may be amended to further such purpose without the consent of the Grantee).

15.Termination of Agreement. This Agreement will terminate on the date by which the Company has fulfilled all of its obligations with respect to the RSUs under this Agreement; provided, however, that any terms or conditions of this Agreement that the Company determines are reasonably necessary to effectuate its purposes shall survive the termination of this Agreement.

16.Non-Transferability and Legends. The Shares underlying the RSUs have not been registered for resale under the Securities Act of 1933, as amended (the “Act”), and may not be sold, transferred or otherwise disposed of unless a registration statement under the Act with respect to such Shares has become effective or unless the Grantee establishes to the satisfaction of the Company that an exemption from such registration is available. After a Share Payment, the paid Shares, as held in book entry form or via certificate form, may bear the following (or similar) legend until such Shares are no longer subject to the Transfer Restrictions or forfeiture: “The sale or other transfer of the shares of stock represented by this certificate or book entry, whether voluntary, involuntary, or by operation of law, is subject to certain restrictions on transfer set forth in a 2022 Interim Chief Executive Officer Restricted Stock Units Award Agreement, a copy of which document may be obtained from the Corporate Secretary of FirstEnergy Corp.”
