This press release contains certain non-GAAP measures, including non-GAAP gross profit, non-GAAP gross margin, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, non-GAAP net income per basic and diluted share, non-GAAP effective tax rate, diluted non-GAAP share count and free cash flow.

The non-GAAP measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. However, the Company believes that this non-GAAP information is useful as an additional means for investors to evaluate its operating performance, when reviewed in conjunction with its GAAP financial statements. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP, and because these amounts are not determined in accordance with GAAP, they should not be used exclusively in evaluating the Company's business and operations. In addition, undue reliance should not be placed upon non-GAAP or operating information because this information is neither standardized across companies nor subjected to the same control activities and audit procedures that produce the Company's GAAP financial results.

The Company's non-GAAP statement of operations measures, including non-GAAP gross profit, non-GAAP gross margin, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, non-GAAP net income per basic and diluted share, non-GAAP effective tax rate, diluted non-GAAP share count and free cash flow, are adjusted to exclude the impact of certain costs, expenses, gains and losses and other specified items that management believes are not indicative of its ongoing operations. These adjusted measures exclude the impact of share-based compensation and eliminate potential differences in results of operations between periods caused by factors such as financing and capital structures, taxation positions or regimes, restructuring, transaction expenses, impairment and other charges. Please refer to the reconciliations of these measures below to what the Company believes are the most directly comparable measures evaluated in accordance with GAAP.

This press release contains “forward-looking statements” within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on management’s beliefs and assumptions and on information currently available to management. Forward-looking statements include information concerning the Company's possible or assumed future results of operations, business strategies, technology developments, financing and investment plans, dividend policy, competitive position, industry, economic and regulatory environment, potential growth opportunities and the effects of competition.

Forward-looking statements involve known and unknown risks, uncertainties, and other factors, many of which are beyond the Company’s control, that may cause the Company’s actual results, performance, or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

These risks and uncertainties may cause actual results to differ materially from CWAN’s current expectations and include, but are not limited to, the Company’s ability to successfully integrate the operations and technology of its acquisitions of Enfusion, Beacon and Bistro (the “Acquisitions”) with those of the Company and to obtain third party data rights, retain and incentivize the employees of the Acquisitions following the close of the Acquisitions, retain the Acquisitions’ clients, repay debt incurred in connection with the Acquisitions and meet financial covenants to be imposed in connection with such debt, risks that synergies and growth from the Acquisitions may not be fully realized or may take longer to realize than expected, the Company's ability to keep pace with rapid technological change and market developments, including artificial intelligence, competitors in its industry, the possibility that market volatility, a downturn in economic conditions or other factors may cause negative trends or fluctuations in the value of the assets on the Company’s platform, the Company's ability to manage growth, the Company’s ability to attract and retain skilled employees, the possibility that the Company’s solutions fail to perform properly, disruptions and failures in the Company's and third parties’ computer equipment, cloud-based services, electronic delivery systems, networks and telecommunications systems and infrastructure, the failure to protect the Company, its customers’ and/or its vendors’ confidential information and/or intellectual property, claims of infringement of others’ intellectual property, factors related to the Company's ownership structure as well as other risks and uncertainties detailed in CWAN’s periodic public filings with the U.S. Securities and Exchange Commission (the “SEC”), including but not limited to those discussed under “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed on February 26, 2025 (as amended by Amendment No. 1 thereto, filed with the SEC on March 7, 2025), and in other periodic reports filed by the Company with the SEC. These filings are available at www.sec.gov and on the Company’s website.

Given these uncertainties, you should not place undue reliance on forward-looking statements. Also, forward-looking statements represent management’s beliefs and assumptions only as of the date of this press release and should not be relied upon as representing the Company’s expectations or beliefs as of any date subsequent to the time they are made. The Company does not undertake to and specifically declines any obligation to update any forward-looking statements that may be made from time to time by or on behalf of the Company.
