This communication may contain forward-looking statements, which include all statements that do not relate solely to historical or current facts, such as statements regarding the Merger and the expected timing of the closing of the Merger and other statements that concern the Company’s expectations, intentions or strategies regarding the future. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “aim,” “potential,” “continue,” “ongoing,” “goal,” “can,” “seek,” “target” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. These forward-looking statements are based on the Company’s beliefs, as well as assumptions made by, and information currently available to, the Company. Because such statements are based on expectations as to future financial and operating results and are not statements of fact, actual results may differ materially from those projected and are subject to a number of known and unknown risks and uncertainties, including, but not limited to: (i) the risk that the Merger may not be completed on the anticipated timeline or at all; (ii) the failure to satisfy any of the conditions to the consummation of the Merger, including the receipt of required approval from the Company’s stockholders and required regulatory approval; (iii) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the Merger Agreement with private equity funds managed by Blackstone, including in circumstances requiring the Company to pay a termination fee; (iv) the effect of the announcement or pendency of the Merger on the Company’s business relationships, operating results and business generally; (v) risks that the Merger disrupts the Company’s current plans and

operations; (vi) the Company’s ability to retain and hire key personnel and maintain relationships with key business partners and customers, and others with whom it does business; (vii) risks related to diverting management’s or employees’ attention during the pendency of the Merger from the Company’s ongoing business operations; (viii) the amount of costs, fees, charges or expenses resulting from the Merger; (ix) potential litigation relating to the Merger; (x) uncertainty as to timing of completion of the Merger and the ability of each party to consummate the Merger; (xi) risks that the benefits of the Merger are not realized when or as expected; (xii) the risk that the price of the Company’s Class A common stock may fluctuate during the pendency of the Merger and may decline significantly if the Merger is not completed; and (xiii) other risks described in the Company’s filings with the U.S. Securities and Exchange Commission (the “SEC”), such as the risks and uncertainties described under the headings “Cautionary Note Regarding Forward-Looking Statements,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other sections of the Company’s Annual Report on Form 10-K, the Company’s Quarterly Reports on Form 10-Q, and in the Company’s other filings with the SEC. While the list of risks and uncertainties presented here is, and the discussion of risks and uncertainties presented in the preliminary proxy statement on Schedule 14A filed by the Company with the SEC on January 11, 2024 (the "Preliminary Proxy Statement") relating to its special meeting of stockholders are, considered representative, no such list or discussion should be considered a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and/or similar risks, any of which could have a material adverse effect on the completion of the Merger and/or the Company’s consolidated financial condition. The forward-looking statements speak only as of the date they are made. Except as required by applicable law or regulation, the Company undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.
