Forward-Looking Statements This Earnings Infographic and supporting materials contain “forward-looking” statements, including ScanSource's FY25 annual outlook and mid-term goals, which involve risks and uncertainties, many of which are beyond ScanSource’s control. No undue reliance should be placed on such statements, as any number of factors could cause actual results to differ materially from anticipated or forecasted results, including, but not limited to, the following factors, which are neither presented in order of importance nor weighted: macroeconomic conditions, including potential prolonged economic weakness, inflation, the failure to manage and implement ScanSource's growth strategy, credit risks involving ScanSource's larger customers and suppliers, changes in interest and exchange rates and regulatory regimes impacting ScanSource's international operations, risk to the business from a cyberattack, a failure of IT systems, failure to hire and retain quality employees, loss of ScanSource's major customers, relationships with key suppliers and customers or a termination or a modification of the terms under which it operates with these key suppliers and customers, changes in ScanSource's operating strategy, and other factors set forth in the "Risk Factors" contained in ScanSource's annual report on Form 10-K for the year ended June 30, 2024. Except as may be required by law, ScanSource expressly disclaims any obligation to update these forward-looking statements to reflect events or circumstances after the date of this Earnings Infographic or otherwise. Non-GAAP Financial Information In addition to disclosing results that are determined in accordance with United States Generally Accepted Accounting Principles (“GAAP”), ScanSource also discloses certain non-GAAP measures, including non-GAAP SG&A expenses, non-GAAP operating income, non-GAAP operating income margin, non-GAAP pre-tax income, non-GAAP net income, non-GAAP diluted EPS, adjusted EBITDA, adjusted EBITDA margin, net debt, adjusted ROIC, free cash flow and net sales in constant currency excluding acquisitions and divestitures (organic growth). A reconciliation of the Company's non-GAAP financial information to GAAP financial information is provided in the following supporting materials and in the Company’s Form 8-K, filed with the SEC, with the quarterly earnings press release for the period indicated. Please see the “Non-GAAP Financial Information” section in the quarterly earnings press release for additional description of ScanSource’s non-GAAP measures. ScanSource discloses forward-looking information that is not presented in accordance with GAAP with respect to adjusted EBITDA, adjusted EBITDA margin, adjusted ROIC, and free cash flow. ScanSource believes that a quantitative reconciliation of such forward-looking information to the most directly comparable GAAP financial measure cannot be made without unreasonable efforts, because a reconciliation of these non-GAAP financial measures would require an estimate of future non-operating items such as acquisitions and divestitures, restructuring costs, impairment charges and other unusual or non-recurring items. Neither the timing nor likelihood of these events, nor their probable significance, can be quantified with a reasonable degree of accuracy. Accordingly, a reconciliation of such forward- looking information to the most directly comparable GAAP financial measure is not provided. 3
