2 Safe Harbor Forward Looking Statements This presentation contains forward-looking statements (including the guidance/outlook contained herein) within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and Section 21E of the Securities Exchange Act of 1934, as amended. The words "estimates," "expects," "anticipates," "believes," "forecasts," "plans," "intends," "may," "will," "should," "shall," "outlook," and variations of these words and similar expressions identify forward-looking statements, which are generally not historical in nature. Certain of these forward-looking statements include statements relating to: strength in core leasing KPIs for the foreseeable future, the scalability and strength of our platform, our ability to expand and sustain expanded margins, and our revenue, Adjusted EBITDA, and Net Capex outlooks. Forward-looking statements are subject to a number of risks, uncertainties, assumptions, and other important factors, many of which are outside our control, which could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Although the Company believes that these forward-looking statements are based on reasonable assumptions, they are predictions and we can give no assurance that any such forward-looking statement will materialize. Important factors that may affect actual results or outcomes include, among others, our ability to acquire and integrate new assets and operations; our ability to achieve planned synergies related to acquisitions; our ability to manage growth and execute our business plan; our estimates of the size of the markets for our products; the rate and degree of market acceptance of our products; the success of other competing modular space and portable storage solutions that exist or may become available; rising costs adversely affecting our profitability; potential litigation involving our Company; general economic and market conditions impacting demand for our products and services; our ability to maintain an effective system of internal controls; and such other risks and uncertainties described in the periodic reports we file with the SEC from time to time (including our Form 10-K/A for the year ended December 31, 2020), which are available through the SEC’s EDGAR system at www.sec.gov and on our website. Any forward-looking statement speaks only at the date in which it is made, and the Company disclaims any obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law. Non-GAAP Financial Measures This presentation includes non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Free Cash Flow Margin, Pro Forma Revenue, Adjusted Gross Profit, Adjusted Gross Profit Percentage, Net Income Excluding Gain/Loss from Warrants, Return on Invested Capital, and Net CAPEX. Adjusted EBITDA is defined as net income (loss) before income tax expense, net interest expense, depreciation and amortization adjusted for non-cash items considered non-core to business operations including net currency gains and losses, goodwill and other impairment charges, restructuring costs, costs to integrate acquired companies, costs incurred related to transactions, non-cash charges for stock compensation plans, gains and losses resulting from changes in fair value and extinguishment of warrant liabilities, and other discrete expenses. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by revenue. Free Cash Flow is defined as net cash provided by operating activities, less purchases of, and proceeds from, rental equipment and property, plant and equipment, which are all included in cash flows from investing activities. Free Cash Flow Margin is defined as Free Cash Flow divided by Total Revenue. Net CAPEX is defined as purchases of rental equipment and refurbishments and purchases of property, plant and equipment (collectively, "Total Capital Expenditures"), less proceeds from sale of rental equipment and proceeds from the sale of property, plant and equipment (collectively, "Total Proceeds"), which are all included in cash flows from investing activities. Our management believes that the presentation of Net CAPEX provides useful information to investors regarding the net capital invested into our rental fleet and plant, property and equipment each year to assist in analyzing the performance of our business. Pro Forma Revenue is defined the same as revenue, but includes pre-acquisition results from Mobile Mini for all periods presented. Adjusted Gross Profit is defined as gross profit plus depreciation on rental equipment. Adjusted Gross Profit Percentage is defined as Adjusted Gross Profit divided by revenue. Return on Invested Capital (ROIC): is defined as adjusted earnings before interest and amortization divided by net assets. Adjusted earnings before interest and amortization is the sum of net income (loss) before income tax expense, net interest expense, amortization adjusted for non-cash items considered non-core to business operations including net currency (gains) losses, goodwill and other impairment charges, restructuring costs, costs to integrate acquired companies, non-cash charges for stock compensation plans, gains and losses resulting from changes in fair value and extinguishment of warrant liabilities, and other discrete expenses, reduced by estimated taxes. Net Income Excluding Gain/Loss from Warrants is defined as Net Income plus or minus the impact of the change in the fair value of the warrant liability. The Company believes that our financial statements that will include the impact of this mark-to-market expense or income may not be necessarily reflective of the actual operating performance of our business. The Company believes that Adjusted EBITDA and Adjusted EBITDA margin are useful to investors because they (i) allow investors to compare performance over various reporting periods on a consistent basis by removing from operating results the impact of items that do not reflect core operating performance; (ii) are used by our board of directors and management to assess our performance; (iii) may, subject to the limitations described below, enable investors to compare the performance of the Company to its competitors; and (iv) provide additional tools for investors to use in evaluating ongoing operating results and trends. The Company believes that pro forma revenue is useful to investors because they allow investors to compare performance of the combined Company over various reporting periods on a consistent basis. The Company believes that Net CAPEX provide useful additional information concerning cash flow available to meet future debt service obligations. Adjusted EBITDA is not a measure of financial performance or liquidity under GAAP and, accordingly, should not be considered as an alternative to net income or cash flow from operating activities as an indicator of operating performance or liquidity. These non-GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. Other companies may calculate Adjusted EBITDA and other non-GAAP financial measures differently, and therefore the Company's non-GAAP financial measures may not be directly comparable to similarly-titled measures of other companies. For reconciliation of the non-GAAP measures used in this presentation (except as explained below), see “Reconciliation of Non-GAAP Financial Measures" included in this presentation. Information reconciling forward-looking Adjusted EBITDA to GAAP financial measures is unavailable to the Company without unreasonable effort. We cannot provide reconciliations of forward-looking Adjusted EBITDA to GAAP financial measures because certain items required for such reconciliations are outside of our control and/or cannot be reasonably predicted, such as the provision for income taxes. Preparation of such reconciliations would require a forward-looking balance sheet, statement of income and statement of cash flow, prepared in accordance with GAAP, and such forward-looking financial statements are unavailable to the Company without unreasonable effort. Although we provide a range of Adjusted EBITDA that we believe will be achieved, we cannot accurately predict all the components of the Adjusted EBITDA calculation. The Company provides Adjusted EBITDA guidance because we believe that Adjusted EBITDA, when viewed with our results under GAAP, provides useful information for the reasons noted above. Merger and Presentation of Entities On March 2, 2020, we announced that we entered into an Agreement and Plan of Merger (the "Merger") with Mobile Mini, Inc. (“Mobile Mini”). During the second quarter, we obtained all required regulatory approvals and stockholder approvals from the Company's and Mobile Mini’s stockholders and we closed the Merger on July 1, 2020 at which time Mobile Mini became a wholly-owned subsidiary of WillScot. Concurrent with the closing of the Merger, we changed our name to WillScot Mobile Mini Holdings Corp. ("WillScot Mobile Mini"). The following presentation is intended to help the reader understand WillScot Mobile Mini, our operations and our present business environment. The discussion of results of operations is presented on a historical basis, as of or for the three months ended September 30, 2021 or prior periods. Our reported results only include Mobile Mini for the periods subsequent to the Merger. Our Pro Forma Results include Mobile Mini's results as if the Merger and related financing transactions had occurred on January 1, 2019, and are a better representation of how the combined company has performed over time. Following the Merger, we expanded our reporting segments from two segments to four reporting segments. The North America Modular Segment aligns with the WillScot legacy business prior to the Merger and the North America Storage, UK Storage and Tank and Pump segments align with the Mobile Mini segments prior to the Merger. Additional Information and Where to Find It Additional information about WillScot Mobile Mini can be found on our investor relations website at www.willscotmobilemini.com.
