214 17 32 55 58 54 184 218 222 191 191 191 107 107 107 Statements made in this presentation concerning Deluxe, the company’s or management’s intentions, expectations, outlook or predictions about future results or events are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements reflect management’s current intentions or beliefs and are subject to risks and uncertainties that could cause actual results or events to vary from stated expectations, which variations could be material and adverse. Factors that could produce such a variation include, but are not limited to, the following: the risk that the proposed Celero transaction may not be completed in a timely manner or at all; the inability to integrate and/or realize the benefits of the Celero transaction, including expected synergies; the occurrence of any fact, event, change, development or circumstance that could give rise to the termination of the Celero acquisition agreement; the failure to satisfy any of the conditions to the consummation of the Celero acquisition, including the receipt of certain regulatory approvals; the risk that the financing necessary to consummate the Celero acquisition may not be obtained, may be delayed, or may be available only on less favorable terms than anticipated; that the announcement of the Celero acquisition could disrupt the company’s or Celero’s relationships with customers, employees or other business partners; changes in local, regional, national and international economic or political conditions, including those resulting from heightened inflation, rising interest rates, a recession, or intensified international hostilities, and the impact they may have on the company, its data, customers or demand for the company’s products and services; the effect of proposed and enacted legislative and regulatory actions affecting the company or the financial services industry as a whole; continuing cost increases and/or declines in the availability of data, materials and other services; the company’s ability to execute its strategy and to realize the intended benefits; the inherent unreliability of earnings, revenue and cash flow predictions due to numerous factors, many of which are beyond the company’s control; declining demand for the company’s checks, check-related products and services and business forms; risks that the company’s strategies intended to drive sustained revenue and earnings growth, despite the continuing decline in checks and forms, are delayed or unsuccessful; intense competition; continued consolidation of financial institutions and/or bank failures, thereby reducing the number of potential customers and referral sources and increasing downward pressure on the company’s revenue and gross profit; risks related to other acquisitions, including integration-related risks and risks that future acquisitions will not be consummated; risks that any such acquisitions do not produce the anticipated results or synergies; risks that the company’s cost reduction initiatives will be delayed or unsuccessful; risks related to any divestitures contemplated or undertaken by the company; performance shortfalls by one or more of the company’s major suppliers, licensors, data or service providers; continuing supply chain and labor supply issues; unanticipated delays, costs and expenses in the development and marketing of products and services, including financial technology and treasury management solutions; the failure of such products and services to deliver the expected revenues and other financial targets; risks related to security breaches, computer malware or other cyber-attacks; risks of interruptions to the company’s website operations or information technology systems; and risks of unfavorable outcomes and the costs to defend litigation and other disputes. The company’s forward-looking statements speak only as of the time made, and management assumes no obligation to publicly update any such statements. Additional information concerning these and other factors that could cause actual results and events to differ materially from the company’s current expectations are contained in the company’s Form 10-K for the year ended December 31, 2025, and other filings made with the SEC. The company undertakes no obligation to update or revise any forward-looking statements to reflect subsequent events, new information or future circumstances. CAUTIONARY STATEMENT Non-GAAP Financial Measures This presentation includes certain non-GAAP financial measures that management uses to evaluate the Company’s operating business, measure performance, and make strategic decisions, including Adjusted EBITDA, Adjusted EBITDA Margin, free cash flow, unlevered free cash flow and net leverage. Adjusted EBITDA and Adjusted EBITDA Margin exclude the impact of interest expense, income taxes, depreciation and amortization, and certain other items that may vary for reasons unrelated to current period operating performance. Adjusted EBITDA excludes the results of the Safeguard small business distributor channel in the Print segment, which was sold in March 2026, and reflects post-transaction terms with the buyer. Free cash flow is defined as net cash provided by operating activities less purchases of capital assets and capitalized software costs. Unlevered Free Cash Flow is defined as tax-effected EBIT, adding back Depreciation & Amortization, and subtracting both the Change in Net Working Capital and Capital Expenditures. Net leverage is calculated as total debt (less cash and cash equivalents) divided by Adjusted EBITDA. Management uses these measures to evaluate operating results, facilitate period-to-period and peer comparisons, and inform strategic decision-making aimed at enhancing performance. These non-GAAP financial measures are not financial measures calculated in accordance with GAAP and should not be considered as a substitute for net income, operating profit, or any other operating performance measure calculated in accordance with GAAP. In addition, although other companies in Deluxe's industry may report measures titled with the same or similar descriptions, such non-GAAP financial measures may be calculated differently from how Deluxe calculates its non-GAAP financial measures, which reduces their overall usefulness as comparative measures. Because of these limitations, you should consider each of the non-GAAP financial measures referenced in this paragraph alongside other financial performance measures, including net income, net cash provided by operating activities and Deluxe's other financial results presented in accordance with GAAP. Deluxe does not provide quantitative reconciliation of forward-looking, non-GAAP financial measures, such as Adjusted EBITDA, Adjusted EBITDA margin, free cash flow and net leverage, to the most directly comparable GAAP financial measures because the Company does not provide outlook guidance on the reconciling items between the non-GAAP and GAAP measures. Due to the significant uncertainty and variability associated with certain forward-looking reconciling items such as restructuring and integration expense, gains and losses on sales of businesses and long-lived assets, and certain legal and environmental expenses, a reconciliation of forward-looking, non-GAAP financial measures to the corresponding GAAP measures cannot be provided without unreasonable effort. The potential impact of such reconciling items is substantial and, based on historical experience, could be material. 1
