Please note that in this document the Company may discuss events or results that have not yet occurred or been realized, commonly referred to as forward-looking statements.

Such statements are based on the Company's expectations, intentions, and projections regarding the Company's future performance, anticipated events or trends and other matters that are not historical facts.

Given these risks and uncertainties, investors are cautioned not to place undue reliance on forward-looking statements. Additional information concerning these risks, uncertainties and other factors that could cause actual results to vary is, or will be, included in the periodic and other reports filed by the Company with the Securities and Exchange Commission. Forward-looking statements included in this document speak only as of the date hereof and,

except as required by applicable law, the Company does not undertake any obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or circumstances after the date of this document.

Non-GAAP Financial Measures

This document contains non-U.S. GAAP financial measures within the meaning of Regulation G promulgated by the Securities and Exchange Commission. The Company uses certain non-U.S. GAAP financial measures that are included in this document and the additional financial information both in explaining its results to shareholders and the investment community and in its internal evaluation and management of its businesses. The Company’s management believes that these non-U.S. GAAP financial measures and the information they provide are useful to investors since these measures (a) permit investors to view the Company’s performance using the same tools that management uses to evaluate the Company’s past performance, reportable business segments and prospects for future performance, (b) permit investors to compare the Company with its peers, (c) in the case of adjusted EBITDA, determines certain elements of management’s incentive compensation, (d) provide consistent period-to-period comparisons of the results, and (e) in the case of organic net revenue growth, enable investors to assess the growth rate of the Company’s existing operations independent of the impact of acquisitions and foreign currency translation. Specifically:

assessment of its significance to the comparability of the Company’s consolidated or segment-level results. Management applies this threshold consistently across periods.

While the Company believes these non-U.S. GAAP measures are useful in evaluating the Company’s performance, this information should be considered as supplemental in nature and not as a substitute for or superior to the related financial information prepared in accordance with U.S. GAAP. Additionally, these non-U.S. GAAP financial measures may differ from similar measures presented by other companies. A reconciliation of these non-U.S. GAAP financial measures is included later in this document.

The Company is unable to provide a quantitative reconciliation of forward-looking non-U.S. GAAP adjusted EBITDA, growth in reported and organic net revenues, and adjusted free cash flow conversion to U.S. GAAP without unreasonable effort due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations, including adjustments that could be made for acquisitions and divestitures, systems and business enablement expenses, business process transformation expenses, impairment charges, transaction and other costs related to acquisitions and divestitures, restructuring costs, miscellaneous capital market activities, and other charges reflected in the Company’s reconciliation of historic numbers, the amount of which, based on historical experience, could be significant.

Additional Information

Following the three-for-two stock split executed on June 30, 2025, all references to the number of shares outstanding, issued shares, and per share amounts of the Company’s common shares have been restated to reflect the effect of the stock split for all historical periods presented in this document.
