Any or all of our forward-looking statements in this release and in any other public statements that we make, are subject to certain risks and uncertainties that could cause actual results to differ materially from those projected. Such risks and uncertainties include, but are not limited to: payments on accounts receivable may be slower than expected, or amounts due on receivables or notes may not be fully collectible; our business could be adversely affected if Marcum LLP (“Marcum”) does not perform to our expectations or we underestimate the liabilities we have assumed; we are dependent on the services of our executive officers, and other key employees, the loss of whom may have a material adverse effect on our business, financial condition and results of operations; restrictions imposed by independence requirements and conflict of interest rules, as well as the nature and terms of our current administrative service agreements, limit our ability to provide services to clients of the attest firms with which we have contractual relationships and the ability of such attest firms to provide attestation services to our clients; our goodwill and other intangible assets could become impaired, which could lead to material non-cash charges against earnings and a material impact on our results of operations and financial condition; certain liabilities resulting from acquisitions are estimated and could lead to a material impact on our results of operations; we may fail to realize the anticipated benefits of acquisitions, or they may prove disruptive and could result in the combined business failing to meet our expectations; recent Securities & Exchange Commission ("SEC") and Public Company Accounting Oversight Board sanctions against Marcum may adversely impact our performance and reputation; if we are unable to implement and maintain effective internal control over financial reporting following the acquisition of Marcum (the “Transaction”), we may fail to prevent or detect material misstatements in our financial statements, in which case investors could lose confidence in the accuracy and completeness of our financial reports and the market price of our common stock may decline; we may not be able to acquire and finance additional businesses, which could limit our ability to pursue our business strategy; we will incur transaction, integration, and restructuring costs in connection with our acquisition program; governmental regulations and interpretations are subject to changes, which could have a material adverse effect on our financial condition; continuing uncertainty in the current economic and geopolitical environment could lead to continuing softness in demand for certain of our services; changes in the United States healthcare environment, including new healthcare legislation, may adversely affect the revenue and margins in our healthcare benefit business; we are subject to risks relating to processing customer transactions for our payroll and other transaction processing businesses; cyberattacks or other security breaches involving our computer systems or the systems of one or more of our vendors could materially and adversely affect our business; we are subject to risk as it relates to software that we license from third parties; we are reliant on information processing systems and any failure or disruptions of these systems could have a material adverse effect on our business, financial condition and results of operations; we could be held liable for errors and omissions; the business services industry is competitive and fragmented, if we are unable to compete effectively, our business, financial condition and results of operations could be negatively impacted; given our levels of share-based compensation, our tax rate may vary significantly depending on our stock price; rapid technological changes could significantly impact our competitive position, client relationships and operating results and our ability to realize the anticipated benefits of the Transaction; climate change legislation or regulations restricting emissions of greenhouse gases could result in increased operating costs; the adverse impact of legislative and regulatory changes in the U.S. and globally, including as a result of the One Big Beautiful Bill Act, on the our tax rate, accounting practices, operations and results; the widespread outbreak of a communicable illness or any other public health crisis could adversely affect our business, financial condition and results of operations; we require a significant amount of cash for interest payments on our debt and to expand our business as planned; terms of our amended and restated credit agreement providing for $2.0 billion in senior secured credit facilities, consisting of a $1.4 billion term loan and $600.0 million revolving credit facility, could adversely affect our ability to run our business and/or reduce stockholder returns; our failure to satisfy covenants in our debt

instruments could cause a default under those instruments; our increased leverage following the Transaction may adversely impact our business; we may be more sensitive to revenue fluctuations than other companies, which could result in fluctuations in the market price of our common stock; the significant number of shares issuable as the stock consideration in the Transaction may adversely impact our stock price; the future issuance of additional shares could adversely affect the price of our common stock; there is volatility in our stock price; and the price of our common stock could be adversely impacted if we do not perform to expectations following the Transaction.

Such forward-looking statements can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Should one or more of these risks materialize, or should the underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated, projected or implied.

Consequently, no forward-looking statement can be guaranteed. A more detailed description of risk factors may be found in our periodic filings with the SEC, including in “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2024. All forward-looking statements made in this release are made only as of the date hereof, and we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. You are advised, however, to consult any further disclosures we make on related subjects in the current, quarterly, periodic and annual reports we file with the SEC.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), we also present Adjusted Net Income (Loss), Adjusted Diluted Earnings Per Share (“EPS”), and Adjusted EBITDA, which are non-GAAP measures. These non-GAAP measures are adjusted to exclude the impact of the Transaction, integration costs, amortization of acquired intangible assets, and other significant non-operating related gains and losses management does not consider ongoing in nature.

The presentation of non-GAAP financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. We use these non-GAAP financial measures for financial and operational decision-making, and to evaluate results relative to employee compensation targets. We believe that these non-GAAP financial measures provide meaningful supplemental information to stockholders, debt holders, and other interested parties in assessing our performance. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance by excluding significant acquisition expenses, certain one-time non-recurring items, and gains and losses that management does not consider ongoing in nature. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key measures used by management in its financial and operational decision-making and (2) they are used by our stockholders and analyst community to determine the health of our business.

Management provides specific information regarding the GAAP amounts excluded from or included in these non-GAAP financial measures. Additionally, management provides reconciliations of these non-GAAP financial measures to their most comparable financial measures in accordance with GAAP. Please see the sections captioned “GAAP Reconciliation” within the Appendix for the reconciliations.
