Pay vs Performance Disclosure |  |  |  |  |  |  |  |
Pay vs Performance Disclosure, Table |  | PAY VERSUS PERFORMANCE DISCLOSURE As described in more detail in “Compensation Discussion and Analysis,” the Company’s executive compensation program has been designed to provide a level of compensation that is strongly dependent upon the achievement of short-term and long-term goals that are aligned with the interests of our stockholders and customers. As such, a substantial portion of pay will only be realized upon strong corporate performance. The Compensation Committee has not designed the compensation program to specifically align the Company’s performance measures with "compensation actually paid" ("CAP") (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. For example, the Company utilizes several performance measures to align executive compensation with Company performance that are not presented in the Pay versus Performance table below. The following tables and supplemental graphical and narrative information present information about CAP, as defined by Item 402(v) of Regulation S-K, and compares CAP to various performance measures, also in accordance with such rules. CAP is a supplemental measure to be viewed alongside performance measures as an addition to the philosophy and strategy of compensation-setting discussed in “Compensation Discussion and Analysis,” and not in replacement thereof.

Compensation Actually Paid vs. Total Shareholder Return |  | CAP v. TSR As demonstrated in the following graph, the amount of compensation paid to the PEOs and the average compensation paid to the other NEOs was aligned with the Company’s TSR performance. A substantial portion of the compensation awarded to each of the NEOs is long-term incentive compensation. For most of the NEOs, performance unit awards comprise 65% of the long-term incentive compensation granted each year, with vesting primarily based upon the Company’s TSR performance against its peer group. As discussed further in “Compensation Discussion and Analysis,” the performance units granted in 2022, which vested at the end of the three-year performance period ended December 31, 2024, provided a payout slightly above target. See the Five-Year Cumulative Return and Total Stockholder Returns graphs in “Compensation Discussion and Analysis – Executive Summary” for information on the Company’s performance over the 5-year period ended December 31, 2024, which was in line with the performance of its peer group, and 10-year period ended December 31, 2024, which exceeded the performance of its peer group, respectively. |  |  |  |  |  |
Compensation Actually Paid vs. Net Income |  | CAP v. WEC Net Income and Adjusted Earnings Per Share (Company-Selected Measure) As demonstrated by the following graphs, during the cumulative five-year period ended December 31, 2024, the compensation paid to the PEOs and the average compensation paid to the other NEOs was aligned with the Company’s net income and EPS performance. In 2024 and 2023, WEC Energy Group's EPS performance is shown on an adjusted (non-GAAP) basis. Pursuant to the terms of the Company’s short-term performance plan, in 2024, almost 75% of the payout was based upon the Company’s adjusted EPS performance, and almost 25% was based upon the Company’s performance against cash flow goals. For information on how the EPS and cash flow targets were established for 2024, see “Compensation Discussion and Analysis." The Company’s strong performance against the EPS and cash flow goals in 2024 resulted in maximum level payouts for each measure. For information on the performance metrics applicable to Mr. Hooper's 2024 annual cash incentive award, see "Compensation Discussion and Analysis." WEC Energy Group’s earnings per share on a GAAP basis were $4.83 for 2024, which includes a $0.06 per share charge to earnings related to certain capital expenditures under the Qualifying Infrastructure Plant (“QIP”) rider that were disallowed by the Illinois Commerce Commission (the “ICC”) as part of PGL's 2016 QIP reconciliation proceeding. Excluding this charge, WEC Energy Group’s adjusted earnings per share were $4.88. PGL has since appealed this decision. The ICC’s disallowance of these expenditures is not indicative of WEC Energy Group’s operating performance in 2024. As a result, the Compensation Committee determined that the Company’s performance against the earnings per share targets should be measured using adjusted earnings per share. With respect to the earnings per share calculation, note that WEC Energy Group’s adjusted earnings per share does not add due to rounding. WEC Energy Group’s earnings per share on a GAAP basis were $4.22 for 2023, which includes a $0.41 per share non-cash charge to earnings related to the ICC's disallowance of an aggregate of $178.9 million of previously incurred capital costs as part of its decisions in the rate cases of the Company’s Illinois utilities. Excluding this charge, WEC Energy Group’s 2023 adjusted earnings per share were $4.63. The ICC’s disallowance of previously incurred capital costs of this nature is not indicative of WEC Energy Group’s operating performance in 2023. As a result, the Compensation Committee determined that the Company’s performance against the earnings per share targets should be measured using adjusted earnings per share. See Appendix A for net income presented on an adjusted basis (non-GAAP) along with a reconciliation to net income, presented on a GAAP basis, for 2024 and 2023. In the graph below, net income is presented on a GAAP basis. EPS is presented on an adjusted (non-GAAP) basis for 2024 and 2023 and on a GAAP basis for years prior to 2023. |  |  |  |  |  |
Compensation Actually Paid vs. Company Selected Measure |  | CAP v. WEC Net Income and Adjusted Earnings Per Share (Company-Selected Measure) As demonstrated by the following graphs, during the cumulative five-year period ended December 31, 2024, the compensation paid to the PEOs and the average compensation paid to the other NEOs was aligned with the Company’s net income and EPS performance. In 2024 and 2023, WEC Energy Group's EPS performance is shown on an adjusted (non-GAAP) basis.

Excluding this charge, WEC Energy Group’s 2023 adjusted earnings per share were $4.63. The ICC’s disallowance of previously incurred capital costs of this nature is not indicative of WEC Energy Group’s operating performance in 2023. As a result, the Compensation Committee determined that the Company’s performance against the earnings per share targets should be measured using adjusted earnings per share. See Appendix A for net income presented on an adjusted basis (non-GAAP) along with a reconciliation to net income, presented on a GAAP basis, for 2024 and 2023. In the graph below, net income is presented on a GAAP basis. EPS is presented on an adjusted (non-GAAP) basis for 2024 and 2023 and on a GAAP basis for years prior to 2023 * Earnings per share for 2020, 2021 and 2022 are presented on a GAAP basis. |  |  |  |  |  |

[2] | Represents the CAP to each of Messrs. Lauber and Fletcher, and the average CAP to the non-PEO NEOs as a group, each as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned or paid during the applicable fiscal years. To calculate the CAP to Messrs. Lauber, and the average CAP to our non-PEO NEOs for the 2024 fiscal year, the following adjustments were made to the SCT total compensation: SCT to CAP Reconciliation
Year | SCT Total ($) | Deductions from SCT Total | Additions to SCT Total | CAP ($)
Change in Pension Value ($) | (a) Equity-based awards Grant Date Fair Value ($) | (b) Pension Benefit Service Costs ($) | (c)(i) Change in Value of Covered Fiscal Year Awards Unvested at Covered Fiscal Year-End ($) | (c)(ii) Change in Value of Prior Years' Awards Unvested at Fiscal Year-End ($) | (c)(iii) Value of Awards Granted and Vested in Covered Fiscal Year ($) | (c)(iv) Change in Value of Prior Years' Awards that Vested in Fiscal Year ($)

(a) Represents the grant date fair value of equity awards as reflected in the "Stock Awards" and "Option Awards" columns of the SCT. (b) Represents the actuarially determined value of the pension benefit accrual for services rendered by each NEO during the applicable year. There were no costs of benefits granted pursuant to a plan amendment during any covered fiscal year that were attributed by the plan's benefit formula to services rendered in periods prior to the plan amendment. (c) Represents (i) the covered fiscal year-end value of any equity awards granted in the covered fiscal year that were outstanding and unvested as of the end of such year; (ii) the amount of the change as of the covered fiscal year-end (from the end of the prior fiscal year) in fair value of any awards granted in prior years that were outstanding and unvested as of the end of the covered fiscal year; (iii) the fair value as of the vesting date of awards granted in a covered fiscal year that vested in the same covered fiscal year; and (iv) the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value for awards granted in prior years that vested during the covered fiscal year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.
