The Company cannot predict with reasonable certainty and without unreasonable effort, the ultimate outcome of unusual gains and losses, the occurrence of matters creating GAAP tax impacts, fluctuations in interest expense or interest income and share-based compensation, and acquisition-related expenses. These items are uncertain, depend on various factors, and could be material to the Company’s results computed in accordance with GAAP. Accordingly, the Company is unable to provide a reconciliation of GAAP net earnings to adjusted EBITDA and adjusted EBITDA margin for the full year 2026 forecast. We wish to caution you that these factors could affect our financial performance and could cause actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in this investor presentation.

Important Note Regarding Pro Forma Results Previously, on June 30, 2025,ePlus inc. (the “Company”) filed a Current Report on Form 8-K (the “Transaction Form 8-K”), disclosing that the Company had completed the sale of 100% of the membership interests of Expo Holdings, LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company (“HoldCo”), thereby selling the Company’s domestic subsidiaries comprising the majority of the Company’s financing business segment, to Marlin Leasing Corporation, a Delaware corporation (“Buyer”), pursuant to that certain Membership Interest Purchase Agreement (the “Purchase Agreement”), dated June 20, 2025, by and among Buyer, the Company and HoldCo (the “Transaction”). On July 7, 2025, the Company amended the T ransaction Form 8-K to provide, as Exhibit 99.2 thereto, the pro forma financial information required by Item 9.01 of Form 8-K (the “Original Pro Forma Financial Statements”). Because the Company customarily provides investor presentations that show select financial information over five fiscal years, the Company provided a Current Report on Form 8-K on September 15, 2025, that furnished certain supplemental pro forma financial information as if the Transaction occurred on April 1, 2020 (the “Supplemental Pro Forma Financial Information” and such Form 8-K being the “Supplemental Pro Forma Form 8-K”). The Supplemental Pro Forma Financial Information was provided as a convenience to investors for information purposes only and reflects many, but not all, adjustments required for pro forma financial information prepared in accordance with Article 11 of Regulation S-X. The pro forma historical results for fiscal years 2023, 2024 and 2025 are presented in accordance with the Original Pro Forma Financial Statements, which provided unaudited pro forma statements of income that were prepared as if the T ransaction occurred on April 1, 2022, and an unaudited pro forma balance sheet that was prepared as if the Transaction occurred on March 31, 2025. Please refer to the Transaction Form 8-K and the Original Pro Forma Financial Statements for additional information. The pro forma historical results for fiscal years 2021 and 2022 are presented in accordance with the Supplemental Pro Forma Financial Information, which provided unaudited pro forma statements of income that were prepared as if the T ransaction occurred on April 1, 2020. Please refer to the Supplemental Pro Forma Form 8-K and the Supplemental Pro Forma Financial Information for additional information. Beginning with the Company’s Quarterly Report on Form 10-Q for the quarter ending June 30, 2025, the historical results of HoldCo were reflected in the Company’s consolidated financial statements as discontinued operations. 29

Reconciliation of Non-GAAP Information We included reconciliations below for the following non-GAAP financial measures: (i) Adjusted EBITDA, (ii) Adjusted EBITDA Margin, (iii) non-GAAP Net Earnings, and (iv) non-GAAP Net Earnings per Common Share - Diluted. We define Adjusted EBITDA as net earnings from continuing operations calculated in accordance with US GAAP , adjusted for the following: interest expense, depreciation and amortization, share-based compensation, acquisition and integration expenses, provision for income taxes, and other income (expense). We define Adjusted EBITDA Margin as Adjusted EBITDA divided by net sales (calculated in accordance with US GAAP), multiplied by 100. Non-GAAP Net Earnings and non-GAAP Net Earnings per Common Share – Diluted are based on net earnings from continuing operations calculated in accordance with US GAAP , adjusted to exclude other income (expense), share based compensation, and acquisition related amortization and acquisition integration expenses, and the related tax effects. We use the above non-GAAP financial measures as supplemental measures of our performance to gain insight into our operating performance and performance trends. We believe that such non-GAAP financial measures provide management and investors a useful measure for period-to-period comparisons of our business and operating results by excluding items that management believes are not reflective of our underlying operating performance. Accordingly, we believe that such non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our operating results. Our use of non-GAAP information as analytical tools has limitations and should not be considered in isolation or as substitutes for analysis of our financial results as reported under GAAP . In addition, other companies, including companies in our industry, might calculate adjusted EBITDA, adjusted EBITDA margin, non-GAAP net earnings, and non-GAAP net earnings per common share, or similarly titled measures differently, which may reduce their usefulness as comparative measures. Basis of Presentation The tables that follow present the non-GAAP financial measures discussed above. We present this non-GAAP information using financial information as originally reported by the Company in its historical financial statements, and on a pro forma basis for our continuing operations (giving effect to the Transaction as if it occurred as previously indicated) and consistent with the Original Pro Forma Financial Statements or the Supplemental Pro Forma Information, as applicable. Additionally , where a caption for a row includes the term “GAAP”, it means that the information presented in the “As Reported” column for that row was derived from the Company’s historical financial statements prepared and presented in accordance with US GAAP . 30
