Peer Group Issuers, Footnote The Peer Group TSR set forth in this table utilizes the peer companies (the “Compensation Peer Group”) used for compensation benchmarking purposes for the year 2025, which is listed in our Compensation Discussion & Analysis section of the proxy statement. The Peer Group TSR is weighted according to the respective peer companies’ stock market capitalization on December 31, 2020. The comparison assumes $100 was invested for the period starting December 31, 2020, through the end of the listed year in the Company and in the Compensation Peer Group, respectively. Historical stock performance is not necessarily indicative of future stock performance.

In previous years, the equity compensation actually paid to the PEO and NEOs was significantly impacted by stock price appreciation related both to the Company’s financial results and to its forward P/E multiple from significant actual and expected revenue growth.

Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the PEO 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 amounts from the Stock Awards column set forth in the Summary Compensation Table.

Name Adjusted Net Income per Diluted Share        
Non-GAAP Measure Description We determined Adjusted EPS 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. Adjusted EPS represents adjusted net income divided by weighted average common shares outstanding on a fully diluted basis. Adjusted net income represents GAAP net income recognizing adjustments, net of tax. Adjustments represent additions and deductions to GAAP net income which include the non-cash impact of amortization of acquired intangible assets, acquisition-related expenses, and the impact of certain expenses and other items that management believes are not indicative of longer-term business trends and operations. This performance measure may not have been the most important financial performance measure for the four preceding fiscal years and we may determine a different financial performance measure to be the most important financial performance measure in future years.
