Forward-Looking Statements

This report and any documents referred to in this report contain forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, and it is intended that all forward-looking statements that Sterling or First Advantage make will be subject to the safe harbor protections created thereby. Forward-looking statements can be identified by forward-looking terminology such as “aim,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “projection,” “seek,” “should,” “will” or “would,” or the negative thereof or other variations thereon or comparable terminology. In particular, statements that address Sterling’s and First Advantage’s future performance, business strategy, future operations, estimates and projections of revenues, losses, costs, expenses, returns, cash flow, and financial position, anticipated benefits of strategic transactions (including acquisitions and divestitures), and plans and objectives of management (including plans for future cash flow from operations), contained in this report or any documents referred to herein are forward-looking statements. These statements also include, but are not limited to, statements regarding the expected benefits of the proposed transaction to Sterling and First Advantage and each of their stockholders and the anticipated timing thereof. Sterling and First Advantage have based these forward-looking statements on current expectations, assumptions, estimates and projections. Such forward-looking statements are only predictions and involve known and unknown risks and uncertainties,

many of which are beyond Sterling’s and First Advantage’s control. Many factors could cause actual future events to differ materially from the forward-looking statements in this report, including but not limited to: (i) the risk that the proposed transaction may not be completed in a timely manner or at all, (ii) the failure to satisfy the conditions to the consummation of the proposed transaction, (iii) the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement, (iv) the effect of the announcement or pendency of the proposed transaction on Sterling’s business relationships, operating results, and business generally, (v) risks that the proposed transaction disrupts current plans and operations of Sterling or First Advantage and potential difficulties in Sterling employee retention as a result of the proposed transaction, (vi) risks related to diverting management’s attention from Sterling’s ongoing business operations, (vii) unexpected costs, charges or expenses resulting from the proposed transaction, (viii) certain restrictions during the pendency of the proposed transaction that may impact Sterling’s ability to pursue certain business opportunities or strategic transactions and (ix) the outcome of any legal proceedings that may be instituted against First Advantage or against Sterling related to the Merger Agreement or the proposed transaction. These and other important factors contained in Sterling’s and First Advantage’s filings with the SEC, including their respective Forms 10-K, 10-Q and 8-K, may cause actual results, performance or achievements to differ materially from those expressed or implied by these forward-looking statements. The forward-looking statements contained in this report are not guarantees of future performance and actual results of operations, financial condition, and liquidity, and the development of the industry in which each of Sterling and First Advantage operates, may differ materially from the forward-looking statements contained in this report. Any forward-looking statement made in this report speaks only as of the date of such statement. Except as required by law, neither Sterling nor First Advantage undertakes any obligation to update or revise, or to publicly announce any update or revision to, any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this report.
