We use the SPADE Defense Index both as a performance modifier under our PSUs granted in fiscal 2026 and in the stock performance graph required by Item 201(e) of Regulation S-K included in our annual report to shareholders.

Name Adjusted EBITDA        
Non-GAAP Measure Description We have designated adjusted EBITDA as our Company-Selected Measure under the PVP Rules. Adjusted EBITDA is the principal financial measure used under our AIP for fiscal 2026 to align annual payouts with performance. Adjusted EBITDA is a non-GAAP financial measure that excludes the effects of pre-established categories of items that the Human Capital and Compensation Committee believes are not reflective of operating performance. These categories are identical to the adjustments that we use for the external reporting of our adjusted EBITDA results in our periodic earnings releases. For a further discussion, see "Compensation Discussion and Analysis—Elements of Fiscal 2026 Target Pay—Annual Incentives" and "Appendix A: Reconciliation of Non-GAAP Measures." The Committee does not consider the calculation of CAP as part of its executive compensation determinations; accordingly, the Committee does not actually use any financial performance measure specifically to link CAP to Company performance.
