Compensation Actually Paid vs. Total Shareholder Return     For the same period, net income increased by $28 million or 6%, and MICP Adjusted EBITDA increased by $8 million or 1%. Also during this period, cumulative Core & Main TSR decreased 5%, and TSR for the S&P 400 MidCap Industrial Index increased 17%. The decreases in PEO CAP, non-PEO NEOs and TSR were primarily driven by the decrease in our share price for fiscal 2025 compared with an increase in share price in fiscal 2024.

Additional 402(v) Disclosure     Reflects the amounts of total compensation reported in the Summary Compensation Table ("SCT") for Stephen LeClair, our former CEO and Principal Executive Officer ("PEO 1"), and Mark Witkowski, who was appointed CEO and Principal Executive Officer ("PEO 2") effective March 31, 2025, replacing Mr. LeClair, for the applicable year. See "Director and Executive Compensation - Summary Compensation Table."Amounts reported in this column represent the amount of compensation actually paid ("CAP") to Mr. Witkowski, Mr. LeClair or the non-PEO NEOs, as applicable, computed in accordance with Item 402(v) of Regulation S-K, the CAP reported for Mr. Witkowski,Mr. LeClair, and the non-PEO NEOs reflects the following adjustments to the total compensation reported in the SCT to determine the applicable CAP:
The fair value of stock options reported in this table were determined using the Black-Scholes option pricing model. The assumptions used for purposes of calculating fair values of stock options as of the vesting date or fiscal year-end date, as applicable, are: (i) the expected life of each stock option is based on the “simplified method” using an average of the remaining vesting period and remaining term as of the applicable vesting date or fiscal year end date; (ii) the exercise price is based on each grant date closing price and asset price is based on the applicable vesting date or fiscal year end closing price; (iii) the risk free interest rate is based on the Treasury Constant Maturity rate closest to the remaining expected life as of the applicable vesting date or fiscal year end date; and (iv) historical volatility is based on daily price history for the expected life of the stock option prior to the applicable vesting date or fiscal year end date. The portion of CAP that is based on fiscal year end share price reflects the share prices of '$53.36, $56.44, $40.55, $21.67, and $23.45 for fiscal year 2025, 2024,2023 ,2022 , and 2021, respectively.
Reflects “Net Income” in the Company’s Consolidated Financial Statements included in the Form 10-K for the applicable fiscal year.These columns represent the value at the end of the respective fiscal year of a $100 initial investment on July 23, 2021, the date of our IPO, for our Class A common stock and the S&P 400 MidCap Industrials Index. We measure the total shareholder return in a fiscal year as the change from the cumulative investment value from the prior fiscal year-end value divided by the cumulative investment value as of the prior fiscal year-end.
Performance Measures
The performance measures listed below represent, in the Company’s assessment, the most important performance measures that link compensation actually paid to our NEOs for fiscal 2025 to company performance. The Company uses MICP Adjusted EBITDA and MICP Working Capital Percentage in its annual cash incentive program, and share price is a key determinant of the value of long-term incentive awards held by our NEOs in the form of stock options and RSUs.
Calculated as year-end accounts receivable plus inventory less accounts payable, as a percentage of fiscal 2025 net sales. The MICP Working Capital Percentage is also adjusted to exclude the same acquisitions as were excluded for the MICP Adjusted EBITDA calculation. See “Director and Executive Compensation – Elements of Our Executive Compensation Program – Short-Term Incentives.”
Additional information regarding these measures, including a reconciliation to the most comparable GAAP measure, is included under the heading “Non-GAAP Reconciliation” beginning on page 53 of this proxy statement and under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Financial Measures” in our 2025 Form 10-K.
As discussed in greater detail under the heading “Director and Executive Compensation,” the Talent and Compensation Committee considers many factors when making decisions concerning the compensation of our executive officers. TSR, net income and MICP Adjusted EBITDA are examples of indicators of the Company’s overall financial performance, which may directly or indirectly impact the Company’s compensation decisions as well as CAP. However, as calculated under SEC rules, CAP reflects adjusted values to unvested and vested equity awards, GAAP valuation assumptions, and projected performance modifiers but does not reflect actual amounts realized by our executives for those awards.
