AMERICAN ELECTRIC POWER CO INC

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”) and certain measures of the financial performance of the Company. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to the Compensation Discussion and Analysis beginning on page 48.

(1)“PEO” means Principal Executive Officer, which was Julie A. Sloat for 2023 and Nicholas K. Akins for 2022, 2021 and 2020. Ms. Sloat replaced Mr. Mr. Akins as CEO effective January 1, 2023, at which point Mr. Akins became Executive Chair. The dollar amounts reported in column (b) are the amounts of total compensation reported for the applicable PEO for 2022, 2021 and 2020 for the corresponding year in the “Total” column of the Summary Compensation Table (“SCT”). Refer to the SCT in the proxy statement for each year for further information.

(2)The dollar amounts reported in column (c) represent the amount of “compensation actually paid” or “CAP” for Ms. Sloat or Mr. Akins, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Ms. Sloat or Mr. Akins during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Ms. Sloat’s or Mr. Akins’ Total Compensation shown in the SCT for the applicable year to calculate “CAP”:

(A)This column reflects the total grant date fair value of equity awards reported in the “Stock Awards” column in the SCT for the applicable year for Ms. Sloat for 2023 and Mr. Akins for 2022, 2021 and 2020. Neither Ms. Sloat nor Mr. Akins received any stock option awards in the years shown.

(B)The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following:

i. The year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year;

ii. The amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year;

iii. For awards that are granted and vest in same applicable year, of which there were not any for Ms. Sloat or Mr. Akins, the fair value as of the vesting date;

iv. For awards granted in prior years that had all applicable vesting conditions satisfied in the applicable year, the change in fair value as of the vesting date (from the end of the prior fiscal year);

v. For awards granted in prior years that are determined to permanently not meet the applicable vesting conditions during the applicable year, of which there were none for Ms. Sloat or Mr. Akins, a deduction equal to the fair value at the end of the prior fiscal year; and

vi. The dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year, of which there were none for Ms. Sloat or Mr. Akins.

The valuation methodology used to determine valuation assumptions and calculate fair values for the TSR portion of the Company’s performance units is consistent with those previously disclosed for the calculation of grant date values and was calculated in accordance with FASB ASC Topic 718 by an independent third party. See Note 15 to the Consolidated Financial Statements included in our Form 10-K for the applicable year for a discussion of the relevant assumptions used in calculating the grant date fair values of equity awards. The EPS and non-emitting generating capacity measures in the Company’s performance shares were valued using target scores as of the grant date, the Company’s projected score for each measure for valuation dates within the performance period, and the actual score for vested awards. These scores were multiplied by the closing share price of AEP common stock on the vesting date or at year end, as applicable, and by number of shares or units then outstanding associated with the weight assigned to each performance measure, including shares or units due to dividend credits.

The prorated portion of performance shares that vest due to the elimination of an executive’s position and separation from AEP service as the result of a consolidation, reorganization, restructuring or downsizing or under circumstances that give rise to Executive Severance Plan Benefits are treated as unvested until the end of the performance period for the purpose of calculating “CAP”. The unrestricted but not yet payable shares granted to Mr. Akins in 2023 were also treated as unvested shares on that date. The amounts deducted or added in calculating the equity award adjustments are as follows:

(C)The amounts included in this column are the Change in Pension Value amounts reported in “Change in Pension Value and Nonqualified Deferred Compensation Earnings” column of the SCT for the applicable year. Neither Ms. Sloat nor Mr. Akins received preferential or above-market earnings on deferred compensation for any of the years shown.

(D)The total pension benefit adjustment for each applicable year includes the aggregate of two components: (i) the actuarially determined service cost for services rendered by Ms. Sloat or Mr. Akins during the applicable year (the “service cost”); and (ii) the entire cost of benefits granted in a plan amendment (or initiation) during the applicable year that are attributed by the benefit formula to services rendered in periods prior to the plan amendment or initiation (the “prior service cost”), of which there were none. In each case, the adjustments are calculated in accordance with U.S. GAAP. The amounts deducted or added in calculating the pension benefit adjustments are as follows:

(3)The dollar amounts reported in column (d) represent the average of the amounts reported for the Company’s named executive officers (NEOs) as a group (excluding Ms. Sloat for 2023 and Mr. Akins for 2020-2022) in the “Total” column of the SCT in the applicable year. Refer to the SCT in the proxy statement for each year for further information. The names of each of the NEOs (excluding Ms. Sloat for 2023 and Mr. Akins for 2020-2022) included for purposes of calculating the average amounts in each applicable year are as follows:

2023: Charles E. Zebula, David M. Feinberg, Christian T. Beam, Peggy I. Simmons, Nicholas K. Akins, and Ann P. Kelly

2022: Julia A. Sloat, Ann P. Kelly, David M. Feinberg, Charles E. Zebula, Paul Chodak III, and Lisa M. Barton

2021: Julia A. Sloat, Lisa M. Barton, David M. Feinberg, Charles E. Zebula, Brian X. Tierney, and Mark C. McCullough

2020: Brian X. Tierney, Lisa M. Barton, David M. Feinberg, and Lana L. Hillebrand

(4)The dollar amounts reported in column (e) represent the average amount of “CAP” for the NEOs as a group (excluding Ms. Sloat for 2023 and Mr. Akins for 2020- 2022), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Ms. Sloat for 2023 and Mr. Akins for 2020-2022) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Ms. Sloat for 2023 and Mr. Akins for 2020-2022) for each year to determine the “CAP”, using the same methodology described above in Note 2:

(A)The amounts deducted or added in calculating the total average equity award adjustments are as follows:

(B)The amounts deducted or added in calculating the total pension benefit adjustments are as follows:

(5)Total shareholder return (TSR) reflects the value at the end of the year shown of $100 invested in the Company’s common stock at the closing market price on the last trading day immediately prior to first year shown. This provides a cumulative TSR value that incorporates both the appreciation or depreciation of the Company’s stock price and the value of dividends, which are assumed to have been reinvested in additional AEP shares. TSR for this purpose was calculated and provided by Bloomberg L.P. as of December 31, 2023. Past performance is not a guarantee of future results.

(6)Represents the market-capitalization weighted average TSR of the S&P Electric Utilities (SP833) that was also used for the stock performance graph required by Item 201(e) of Regulation S-K in our Annual Report for the year ended December 31, 2023. This is an index of peer companies provided by S&P Dow Jones Indices LLC for which the TSR was calculated and provided by Bloomberg L.P. as of December 31, 2023.

(7)The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year.

(8)Operating earnings per share is a non-GAAP financial measure. Exhibit A to the proxy statement for the corresponding year contains a full reconciliation of GAAP earnings per share to non-GAAP operating earnings per share for that year. For purposes of Item 402(v) of Regulation S-K, the Company has determined that operating earnings per share is the financial performance measure that, in the Company’s assessment, represents the most important performance measure used by the Company to link “CAP” of the Company’s NEOs to Company performance for the most recent two fiscal years. This performance measure may not have been the most important financial performance measure for 2020 or 2021 and the Company may determine a different financial performance measure to be the most important financial performance measure in future years.
