Historical stock performance is not necessarily indicative of future stock performance.

Non-GAAP Measure Description 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 2025. 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.
