© 2026 First Advantage NON- GAAP FINANCIAL INFORMATION This presentation contains “non-GAAP financial measures” that are financial measures that either exclude or include amounts that are not excluded or included in the most directly comparable measures calculated and presented in accordance with accounting principles generally accepted in the United States (“GAAP”). Specifically, we make use of the non-GAAP financial measures “Adjusted EBITDA,” “Adjusted EBITDA Margin,” “Adjusted Net Income,” “Adjusted Diluted Earnings Per Share,” and “Constant Currency Revenues.” Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted Earnings Per Share, and Constant Currency Revenues have been presented in this presentation as supplemental measures of financial performance that are not required by or presented in accordance with GAAP because we believe they assist investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. Management believes these non-GAAP measures are useful to investors in highlighting trends in our operating performance, while other measures can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate, and capital investments. Management uses Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted Earnings Per Share, and Constant Currency Revenues to supplement GAAP measures of performance in the evaluation of the effectiveness of our business strategies, to make budgeting decisions, to establish discretionary annual incentive compensation, and to compare our performance against that of other peer companies using similar measures. Management supplements GAAP results with non-GAAP financial measures to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Diluted Earnings Per Share, and Constant Currency Revenues are not recognized terms under GAAP and should not be considered as an alternative to net income (loss) as a measure of financial performance or cash provided by (used in) operating activities as a measure of liquidity, or any other performance measure derived in accordance with GAAP. We define Adjusted EBITDA as net income (loss) before interest, taxes, depreciation, and amortization, and as further adjusted for loss on extinguishment of debt, share-based compensation, transaction and acquisition-related charges, integration and restructuring charges, and other non-cash charges. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by total revenues. We define Adjusted Net Income for a particular period as net income (loss) before taxes adjusted for debt-related costs, acquisition-related depreciation and amortization, share-based compensation, transaction and acquisition-related charges, integration and restructuring charges, and other non-cash charges, to which we then apply the related effective tax rate. We define Adjusted Diluted Earnings Per Share as Adjusted Net Income divided by adjusted weighted average number of shares outstanding—diluted. We define Constant Currency Revenues as current period revenues translated using prior-year period exchange rates. For reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures, see the reconciliations included at the end of this presentation. The presentations of these measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Because not all companies use identical calculations, the presentations of these measures may not be comparable to other similarly titled measures of other companies and can differ significantly from company to company. Numerical figures included in the reconciliations have been subject to rounding adjustments. Accordingly, numerical figures shown as totals in various tables may not be arithmetic aggregations of the figures that precede them. To facilitate comparability, we present pro forma combined company results, consisting of First Advantage and Sterling historical results and certain pro forma adjustments as if the acquisition of Sterling had occurred on 1/1/2023. The pro forma information does not constitute Article 11 pro forma information. FORWARD- LOOKING STATEMENTS This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.

For additional information on these and other factors that could cause First Advantage’s actual results to differ materially from expected results, please see our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission (the “SEC”), as such factors may be updated from time to time in our filings with the SEC, which are or will be accessible on the SEC’s website at www.sec.gov.
