Pay vs Performance Disclosure, Table

PAY VERSUS PERFORMANCE

Pursuant to a mandate of the Dodd-Frank Act commonly referred to as "Pay versus Performance," the SEC has adopted a rule requiring registrants to provide a clear description of (1) the relationship between executive compensation actually paid ("CAP") to the Company's NEOs (including the principal executive officer or person acting in a similar capacity during the last completed fiscal year ("CEO")) and the Company’s cumulative total shareholder return (“TSR”), net income and a third Company-selected financial measure, and (2) the relationship between the Company's TSR and the TSR of a peer group chosen by the Company.

The following table provides information regarding CAP to our CEO and non-CEO NEOs during each of the past five fiscal years, as well as TSR, net income, and our Company-selected measure, adjusted EBITDA. See the “Compensation Discussion and Analysis" section above for a comprehensive discussion of our executive compensation program and philosophy.

(1)

These columns reflect the amounts reported in the “Summary Compensation Table” for Ms. Hurd, our current CEO, Mr. Hendrix, our former CEO, and the average for our non-CEO NEOs, for each of the years listed. The non-CEO NEOs for whom the average compensation is presented in this table are Messrs. Foshee, Hausmann, Poppens and Stansfield, for each of the years presented.

(2)

TSR is calculated based on an initial fixed investment of $100 on December 31, 2020 (the final trading day before our 2021 fiscal year), assuming reinvestment of dividends, through the end of the covered fiscal year presented.

(3)

The peer group used for the TSR calculation are the same companies comprising the “self-determined peer group” index used for compensation decision making (as described in the Compensation Discussion and Analysis in the proxy statement for each applicable fiscal year) and used to create the stock performance graph included in the Company’s Annual Report on Form 10-K for each applicable fiscal year.

(4)

Adjusted EBITDA is a non-GAAP financial measure. Please see Appendix A for a reconciliation of this non-GAAP measure to the most directly comparable GAAP measure.

Recovery of Erroneously Awarded Compensation	Dec. 28, 2025
Restatement Determination Date:: 2025-12-31
Erroneously Awarded Compensation Recovery
Erroneous Compensation Analysis	Clawback Policy The Committee has adopted a Clawback Policy, which requires the Committee to take such action as it deems necessary to recover reasonably promptly from executive officers certain incentive-based compensation, including both cash and equity, following a restatement of the Company’s financial statements. Pursuant to the Clawback Policy, in the event the Company is required to prepare an accounting restatement due to the Company’s material noncompliance with any financial reporting requirement under the U.S. federal securities laws (an “Accounting Restatement”), regardless of individual fault, the Committee must require the forfeiture or reimbursement, subject to the terms of the Clawback Policy, from any current or former “Covered Executive” (meaning, any officer of the Company covered by Section 16(a) of the Securities Exchange Act) of the Company, any excess incentive-based compensation awarded during the three completed fiscal years immediately preceding the date on which the Company is required to prepare an Accounting Restatement. Excess incentive-based compensation, as defined in the Clawback Policy, essentially means the amount or value of incentive-based compensation granted, earned or vested (“Awarded”) in excess of what would have been Awarded to that Covered Executive based on the Accounting Restatement. The Committee or the Board of Directors shall recover such excess incentive-based compensation unless the Committee determines such recovery would be impracticable pursuant to the terms of the Clawback Policy.
