The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company’s NEOs. These amounts reflect the Summary Compensation Table Total with certain adjustments as described in footnote 3 below.

(3)
Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the PEOs and the Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards column are the totals from the Stock Awards column set forth in the Summary Compensation Table.

The Peer Group TSR set forth in this table utilizes the S&P 500 Construction Materials Industry Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 30, 2023. The comparison assumes $100 was invested for the period starting December 28, 2019, through the end of the listed year in the Company and in the S&P 500 Construction Materials Industry Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.

(5)
We determined Adjusted EBITDA to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2023. Adjusted EBITDA is a non-GAAP measure. For more information on Adjusted EBITDA, please see the “Elements of Pay: Annual Cash Incentives” section of the Compensation Discussion & Analysis in this proxy statement. This performance measure may not have been the most important financial performance measure in prior years and we may determine a different financial performance measure to be the most important financial performance measure in future years.
