2 This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements relate to the Company’s current expectations, beliefs, and projections concerning matters that are not historical facts and are not guarantees of future performance. Forward-looking statements involve uncertainties, risks, assumptions and contingencies, many of which are outside the Company’s control and which may cause actual results to differ materially from those described in or implied by any forward-looking statement. Such statements include, but are not limited to, information provided regarding expected revenues, earnings, growth, and operational performance for fiscal 2026 and thereafter. For a further discussion of factors that could cause the Company's future results to differ materially from any forward-looking statements, see the section entitled "Risk Factors" in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2025 and other risks described therein and in documents subsequently filed by the Company from time to time with the Securities and Exchange Commission. All forward-looking statements are based on currently available information and speak only as of the date on which they are made. Investors should not place undue reliance on forward-looking statements as a prediction of actual results. The Company assumes no obligation to update any forward-looking statement made in this investor presentation that becomes untrue because of subsequent events, new information or otherwise, except to the extent it is required to do so in connection with its ongoing requirements under federal securities laws. This presentation includes certain non-GAAP financial measures. The presentation of these non-GAAP figures is provided to allow for the comparison of the underlying performance of the Company, net of impairment, restructuring, and other charges (including certain legal costs), amortization of intangible assets acquired through business acquisitions, gain on sale of property in fiscal 2022, and non- cash interest expense primarily related to convertible debt, and their associated tax effects, and the impact of discrete income tax items including charges resulting from the Tax Cuts and Jobs Act (the “Tax Act”). Although we exclude amortization of acquired intangible assets from our non-GAAP figures, revenue generated from such intangibles is included within revenue in determining non-GAAP financial performance of the Company. Management believes that these non-GAAP financial measures provide (i) enhanced insight into the ongoing operations of the Company, (ii) meaningful information regarding the Company's financial results (excluding amounts management does not view as reflective of ongoing operating results) for purposes of planning, forecasting, and assessing the performance of the Company’s businesses, (iii) a meaningful comparison of financial results of the current period against results of past periods, and (iv) financial results that are more comparable to financial results of peer companies than are GAAP figures. Non-GAAP financial measures should not be assessed in isolation or as a substitute for measures of financial performance prepared in accordance with GAAP. These non-GAAP measures may not be the same as measures used by other companies due to possible differences in methods and in the items or events for which adjustments are made. Reconciliations of GAAP to non-GAAP financial information are included within this presentation. Safe Harbor 2
