Non-GAAP Financial Measures

This presentation 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 presentation 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 and (c) determine certain elements of management's incentive compensation. Specifically:

• The Company's management believes that adjusted gross profit, adjusted selling, general and administrative ("SG&A") expenses, adjusted net income, and adjusted earnings per share, which are non-GAAP financial measures that exclude business transformation and other expenses for the integration of acquired businesses, the impact and results of businesses classified as assets held-for-sale and businesses divested, and one-time and other events such as impairment charges, share-based compensation, transaction and other costs related to acquisitions, amortization of intangible assets, net COVID-19 relief, non-service pension benefit, severance related costs related to corporate leadership changes and certain tax benefits from the acquisition of APi Group, Inc. (the "APi Acquisition") are useful because they provide investors with a meaningful perspective on the current underlying performance of the Company's core ongoing operations.
• The Company also presents organic changes in net revenues on a consolidated basis or segment specific basis to provide a more complete understanding of underlying revenue trends by providing net revenues on a consistent basis as it excludes the impacts of material acquisitions, completed divestitures, and changes in foreign currency from year-over- year comparisons on reported net revenues, calculated as the difference between the reported net revenues for the current period and reported net revenues for the current period converted at the prior year average monthly exchange rates (excluding acquisitions and divestitures). The remainder is divided by the prior year net revenues, excluding the impacts of material acquisitions and completed divestitures.

Non-GAAP Financial Measures (Cont'd)

• Earnings before interest, taxes, depreciation and amortization ("EBITDA") is the measure of profitability used by management to manage its segments and, accordingly, in its segment reporting. The Company supplements the reporting of its consolidated financial information with certain non-U.S. GAAP financial measures, including EBITDA and adjusted EBITDA, which is defined as EBITDA excluding the impact of certain non-cash and other specifically identified items ("adjusted EBITDA"). Adjusted EBITDA margin is calculated as adjusted EBITDA divided by net revenues. The Company believes these non-U.S. GAAP measures provide meaningful information and help investors understand the Company's financial results and assess its prospects for future performance. The Company uses EBITDA and adjusted EBITDA to evaluate its performance, both internally and as compared with its peers, because it excludes certain items that may not be indicative of the Company's core operating results. Consolidated EBITDA is calculated in a manner consistent with segment EBITDA, which is a measure of segment profitability.
• The Company presents free cash flow, adjusted free cash flow and adjusted free cash flow conversion, which are liquidity measures used by management as factors in determining the amount of cash that is available for working capital needs or other uses of cash, however, it does not represent residual cash flows available for discretionary expenditures. Free cash flow is defined as cash provided by (used in) operating activities less capital expenditures. Adjusted free cash flow is defined as cash provided by (used in) operating activities plus or minus events including, but not limited to, transaction and other costs related to acquisitions, business transformation and other expenses for the integration of acquired businesses, impacts of businesses classified as assets held-for-sale and businesses divested, and one-time and other events such COVID related payroll tax deferral and relief items. Adjusted free cash flow conversion is defined as adjusted free cash flow as a percentage of adjusted EBITDA.

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 in this presentation.

Beginning with the first quarter of 2022, the Company has combined its Industrial Services and Specialty Services segments into one operating segment. Certain prior year amounts have been recast to conform to this presentation and the information in the tables below has been retroactively adjusted to reflect these changes in reporting segments.
