PHOENIX, May 02, 2024 (GLOBE NEWSWIRE) -- WillScot Mobile Mini Holdings Corp. (“WillScot Mobile Mini” or the “Company”) (Nasdaq: WSC), a leader in innovative temporary flexible space solutions, today announced first quarter 2024 results and provided an update on operations and the current market environment, including the following highlights:

Q1 2024

• Revenue increased 4% to $587 million and Income from continuing operations was $56 million. Income from operations included approximately $15 million of integration and transaction-related expenses. Adjusted EBITDA was flat year-over-year at $248 million.
• Generated Net cash provided by operating activities of $209 million and Free Cash Flow of $144 million, both up 40% year-over-year, with Free Cash Flow Margin of 24.5%, which increased by 660 basis points.
• Maintained leverage sequentially at 3.3x Net Debt to Adjusted EBITDA as of March 31, 2024, inside our target range of 3.0x to 3.5x.
• Generated 17% Return on Invested Capital² ("ROIC") over the last 12 months.
• Returned $595 million to shareholders by repurchasing 13.9 million shares of Common Stock, reducing our share count by 6.4% over the last twelve months as of March 31, 2024¹.
• Maintained our FY 2024 Adjusted EBITDA outlook range of $1,125 million to $1,200 million, representing 6% to 13% growth in our continuing operations versus 2023.
• On January 29, 2024, WSC announced a definitive agreement to acquire McGrath RentCorp (NASDAQ: MGRC). The Company expects the transaction to close in 2024.

Brad Soultz, Chief Executive Officer of WillScot Mobile Mini, commented, "Our Company delivered results in Q1 that were in line with our overall expectations for the year. Leasing revenue was up 5%, despite the ongoing contraction in non-residential construction square footage starts. Modular activations are building both sequentially and year-over-year, offsetting continued headwinds on Storage activations. And we continue to see healthy growth in both rates and Value-Added Products (VAPS) across all product lines, so our commercial performance and outlook remain solid given the market backdrop."

Soultz continued, "The team also completed the final systems and field harmonization that we contemplated in the original WillScot and Mobile Mini integration plan. In January, we combined our legacy WillScot and Mobile Mini sales and operations teams under a single leadership structure, organized by geography. This allows us to go-to-market locally with a single team that can service our customers across our full offering of turnkey space solutions. To support this field integration, in March we upgraded our field service and dispatch system, which allows us to better utilize our operational resources across all product lines while improving execution and customer communication. And we are advancing our digital roadmap using customer feedback to enhance nearly every aspect of the customer experience.”

Soultz concluded, "These initiatives allow us to even more seamlessly deliver our ever-expanding portfolio of space solutions to our entire customer base and will ensure that we continue to offer the most compelling value proposition in the industry. And the McGrath acquisition, which we expect to close in 2024, will further accelerate our growth and proportionally increase the $1B of idiosyncratic growth levers fully in our control, which we believe will benefit all stakeholders for years to come. At WillScot Mobile Mini, we have a proven formula to drive sustainable growth and returns, and I have never been more excited by the execution of our team across all organic and inorganic levers to drive long-term value for our customers, employees, communities, and shareholders."

First Quarter 2024 Results²

Tim Boswell, President and Chief Financial Officer, commented, "Q1 2024 results were in line with our overall plans for the year, so we are maintaining our 2024 outlook. Margins contracted sequentially and year-over-year as expected to support increases in modular activation volumes and related maintenance activity in Q1 and heading into Q2, and we expect margins to reflate through the course of the year as lease revenues build sequentially. So, we are maintaining our 2024 outlook of $2,485 - $2,635 million of revenue and $1,125 - $1,200 million of Adjusted EBITDA, with approximately 50 basis points of margin expansion at the midpoint."

Boswell concluded, "Cash flow and returns continue to be highlights, despite approximately $15 million of integration and transaction-related expenses that we incurred during the quarter. We generated $144 million of Free Cash Flow in the quarter, which was up 40% year-over-year, and a Free Cash Flow Margin of 24.5%, which was up 660 basis points year-over-year. Return on Invested Capital of 17% over the last 12 months was in line with our updated target range. And Net Debt to Adjusted EBITDA of 3.3x is on a downward trajectory heading into Q2. With these results and visibility into our run-rate heading into 2025, we will resume allocating capital between organic investments, acquisitions, and share repurchases, while maintaining the financing plan that is in place to close the McGrath acquisition later in the year, and we are confident in how these investments will amplify returns from the natural compounding of the business over time."

Capitalization and Liquidity Update²

As of and for the three months ended March 31, 2024, except where noted:

• Generated $144 million of Free Cash Flow in the first quarter, up 40% year-over-year.
• Invested $43 million of capital in one acquisition during the quarter, with $526 million invested in the last 12 months.
• Increased excess availability to approximately $1.3 billion under our asset backed revolving credit facility.
• Weighted average pre-tax interest rate, after giving effect to both the 3.44% floating-to-fixed interest rate swap that we executed in January 2023 and the 3.70% floating-to-fixed interest rate swap that we executed in January 2024 is approximately 5.9%. Annual cash interest expense based on the current debt structure and benchmark rates is approximately $207 million, or approximately $220 million inclusive of non-cash deferred financing fees. Our debt structure is approximately 79% / 21% fixed-to-floating after giving effect to all interest rate swaps.
• No debt maturities prior to 2025. We have ample liquidity available to redeem or refinance our $527 million 2025 notes, using either our asset backed revolver or other sources of capital, and intend to do so opportunistically prior to maturity in a manner that optimizes our interest costs.
• Leverage is at 3.3x last 12 months Adjusted EBITDA from continuing operations of $1,063 million, which is inside our target range of 3.0x to 3.5x.

2024 Outlook ^{2, 3, 4}
This guidance is subject to risks and uncertainties, including those described in "Forward-Looking Statements" below.

1 - Assumes common shares outstanding as of March 31, 2024 versus common shares outstanding as of March 31, 2023.
2 - Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Free Cash Flow Margin, Net Debt to Adjusted EBITDA and Return on Invested Capital are non-GAAP financial measures. Further information and reconciliations for these non-GAAP measures to the most directly comparable financial measure under generally accepted accounting principles in the US ("GAAP") are included at the end of this press release.
3 - Information reconciling forward-looking Adjusted EBITDA, Net CAPEX, and Free Cash Flow to GAAP financial measures is unavailable to the Company without unreasonable effort and therefore neither the most comparable GAAP measures nor reconciliations to the most comparable GAAP measures are provided.
4 - Net CAPEX is a non-GAAP financial measure. Please see the non-GAAP reconciliation tables included at the end of this press release.
5 - Free Cash Flow incorporates results from discontinued operations. For comparability, we add back discontinued operations to reported revenue to calculate Free Cash Flow Margin.

Non-GAAP Financial Measures

This press release includes non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin from continuing operations, Free Cash Flow, Free Cash Flow Margin, Return on Invested Capital, Net CAPEX and Net Debt to Adjusted EBITDA ratio. Adjusted EBITDA is defined as net income (loss) plus net interest (income) expense, income tax expense (benefit), depreciation and amortization adjusted to exclude certain non-cash items and the effect of what we consider transactions or events not related to our core 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 common stock warrant liabilities, and other discrete expenses. Adjusted EBITDA Margin from continuing operations 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 revenue. Return on Invested Capital is defined as adjusted earnings before interest and amortization divided by average invested capital. Adjusted earnings before interest and amortization is the sum of income (loss) before income tax expense, net interest (income) 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 common stock warrant liabilities, and other discrete expenses, reduced by our estimated statutory tax rate. Given we are not a significant US taxpayer due to our current tax attributes, we include estimated taxes at our current statutory tax rate of approximately 26%. Net assets is total assets less goodwill and intangible assets, net and all non-interest bearing liabilities and is calculated as a five quarter average. 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 the 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. Net Debt to Adjusted EBITDA ratio is defined as Net Debt divided by Adjusted EBITDA. 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; (iv) provide additional tools for investors to use in evaluating ongoing operating results and trends; and (v) align with definitions in our credit agreement. The Company believes that Free Cash Flow and Free Cash Flow Margin are useful to investors because they allow investors to compare cash generation performance over various reporting periods and against peers. The Company believes that Return on Invested Capital provides information about the long-term health and profitability of the business relative to the Company's cost of capital. The Company 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. 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 reconciliations of the non-GAAP measures used in this press release (except as explained below), see “Reconciliation of Non-GAAP Financial Measures" included in this press release.

Information regarding the most comparable GAAP financial measures and reconciling forward-looking Adjusted EBITDA, Net CAPEX, and Free Cash Flow to those GAAP financial measures is unavailable to the Company without unreasonable effort. We cannot provide the most comparable GAAP financial measures nor reconciliations of forward-looking Adjusted EBITDA, Net CAPEX, and Free Cash Flow 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 ranges of Adjusted EBITDA and Net CAPEX that we believe will be achieved, we cannot accurately predict all the components of the Adjusted EBITDA and Net CAPEX calculations. The Company provides Adjusted EBITDA and Net CAPEX guidance because we believe that Adjusted EBITDA and Net CAPEX, when viewed with our results under GAAP, provides useful information for the reasons noted above.

Recent Developments

Entry into an Agreement to Acquire McGrath RentCorp

On January 28, 2024, the Company, along with its newly formed subsidiaries, Brunello Merger Sub I, Inc. (“Merger Sub I”) and Brunello Merger Sub II, LLC (“Merger Sub II”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with McGrath RentCorp ("McGrath"). Merger Sub I will merge with and into McGrath (the “First-Step Merger”), with McGrath surviving the First-Step Merger and, immediately thereafter, McGrath will merge with and into Merger Sub II (the “Second-Step Merger” and together with the First-Step Merger, the “McGrath Acquisition”), with Merger Sub II surviving the Second-Step Merger as a wholly owned subsidiary of the Company. At the effective time of the First-Step Merger, and subject to the terms and subject to the conditions set forth in the Merger Agreement, each outstanding share of the common stock of McGrath shall be converted into the right to receive either (i) $123.00 in cash or (ii) 2.8211 shares of validly issued, fully paid and nonassessable shares of the Company’s common stock. McGrath shareholders will receive for each of their shares either $123.00 in cash or 2.8211 shares of WillScot Mobile Mini common stock, as determined pursuant to the election and allocation procedures in the merger agreement under which 60% of McGrath’s outstanding shares will be converted into the cash consideration and 40% of McGrath’s outstanding shares will be converted into the stock consideration. Under the terms of the Merger Agreement, we expect McGrath’s shareholders would own approximately 12.6% of the Company following the McGrath Acquisition.

The McGrath Acquisition has been approved by the respective boards of directors of the Company and McGrath. The McGrath Acquisition is subject to customary closing conditions, including receipt of regulatory approval and approval by McGrath’s shareholders, and is expected to close in 2024.

In connection with the Merger Agreement, the Company entered into a commitment letter on January 28, 2024, which was further amended and restated on February 12, 2024 (the "Commitment Letter"), pursuant to which certain financial institutions have committed to make available to Williams Scotsman, Inc. (WSI), in accordance with the terms of the Commitment Letter, (i) a $500 million eight year senior secured bridge credit facility, (ii) a $500 million five year senior secured bridge credit facility and (iii) an upsize to WSI's existing $3.7 billion ABL Facility by $750 million to $4.5 billion to repay McGrath's existing credit facilities and notes, fund the cash portion of the consideration, and pay the fees, costs and expenses incurred in connection with the McGrath Acquisition and the related transactions, subject to customary conditions.

Additional Information and Where to Find It

Additional information can be found on the company's website at www.willscotmobilemini.com.

Reconciliation of Non-GAAP Financial Measures

In addition to using GAAP financial measurements, we use certain non-GAAP financial information that we believe is important for purposes of comparison to prior periods and development of future projections and earnings growth prospects. This information is also used by management to measure the profitability of our ongoing operations and analyze our business performance and trends.

We evaluate business performance on Adjusted EBITDA, a non-GAAP measure that excludes certain items as described below. We believe that evaluating performance excluding such items is meaningful because it provides insight with respect to intrinsic and ongoing operating results of the Company.

We also regularly evaluate gross profit to assist in the assessment of the operational performance. We consider Adjusted EBITDA to be the more important metric because it more fully captures the business performance, inclusive of indirect costs.

We also evaluate Free Cash Flow, a non-GAAP measure that provides useful information concerning cash flow available to fund our capital allocation alternatives.

Adjusted EBITDA From Continuing Operations

We define EBITDA as net income (loss) plus interest (income) expense, income tax expense (benefit), depreciation and amortization. Our adjusted EBITDA ("Adjusted EBITDA") reflects the following further adjustments to EBITDA to exclude certain non-cash items and the effect of what we consider transactions or events not related to our core business operations:

• Currency (gains) losses, net on monetary assets and liabilities denominated in foreign currencies other than the subsidiaries’ functional currency.
• Goodwill and other impairment charges related to non-cash costs associated with impairment charges to goodwill, other intangibles, rental fleet and property, plant and equipment.
• Restructuring costs, lease impairment expense, and other related charges associated with restructuring plans designed to streamline operations and reduce costs including employee termination costs.
• Transaction costs including legal and professional fees and other transaction specific related costs.
• Costs to integrate acquired companies, including outside professional fees, non-capitalized costs associated with system integrations, non-lease branch and fleet relocation expenses, employee training costs, and other costs required to realize cost or revenue synergies.
• Non-cash charges for stock compensation plans.
• Other expense, including consulting expenses related to certain one-time projects, financing costs not classified as interest expense, and gains and losses on disposals of property, plant, and equipment.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider the measure in isolation or as a substitute for net income (loss), cash flow from operations or other methods of analyzing the Company’s results as reported under US GAAP. Some of these limitations are:

• Adjusted EBITDA does not reflect changes in, or cash requirements for our working capital needs;
• Adjusted EBITDA does not reflect our interest expense, or the cash requirements necessary to service interest or principal payments, on our indebtedness;
• Adjusted EBITDA does not reflect our tax expense or the cash requirements to pay our taxes;
• Adjusted EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments;
• Adjusted EBITDA does not reflect the impact on earnings or changes resulting from matters that we consider not to be indicative of our future operations;
• Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and Adjusted EBITDA does not reflect any cash requirements for such replacements; and
• Other companies in our industry may calculate Adjusted EBITDA differently, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered as discretionary cash available to reinvest in the growth of our business or as measures of cash that will be available to meet our obligations.

The following table provides unaudited reconciliations of Income from continuing operations to Adjusted EBITDA from continuing operations:

Adjusted EBITDA Margin From Continuing Operations

We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue. Management believes that the presentation of Adjusted EBITDA Margin provides useful information to investors regarding the performance of our business. The following table provides an unaudited comparison of Adjusted EBITDA Margin to Gross Profit Margin:

Net Debt to Adjusted EBITDA From Continuing Operations Ratio

Net Debt to Adjusted EBITDA ratio is defined as Net Debt divided by Adjusted EBITDA from continuing operations from the last twelve months. We define Net Debt as total debt from continuing operations net of total cash and cash equivalents from continuing operations. Management believes that the presentation of Net Debt to Adjusted EBITDA ratio provides useful information to investors regarding the performance of our business. The following table provides an unaudited reconciliation of Net Debt to Adjusted EBITDA ratio:

Free Cash Flow and Free Cash Flow Margin

Free Cash Flow is a non-GAAP measure. We define Free Cash Flow 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 including discontinued operations. Management believes that the presentation of Free Cash Flow and Free Cash Flow Margin provides useful additional information concerning cash flow available to fund our capital allocation alternatives. Free Cash Flow as presented includes amounts for the former UK Storage Solutions segment through January 31, 2023. The following table provides unaudited reconciliations of Free Cash Flow and Free Cash Flow Margin:

Net CAPEX

We define Net CAPEX as purchases of rental equipment and refurbishments and purchases of property, plant and equipment (collectively, "Total Capital Expenditures"), less proceeds from the 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. Management believes that the presentation of Net CAPEX provides useful information regarding the net capital invested in our rental fleet and property, plant and equipment each year to assist in analyzing the performance of our business. As presented below, Net CAPEX includes amounts for the former UK Storage Solutions segment through January 31, 2023.

The following table provides unaudited reconciliations of Net CAPEX, which is calculated using metrics from our Statements of Cash Flows:

Return on Invested Capital

Return on Invested Capital is defined as adjusted earnings before interest and amortization divided by average invested capital. Adjusted earnings before interest and amortization is the sum of income (loss) before income tax expense, net interest (income) 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 common stock warrant liabilities, and other discrete expenses, reduced by estimated taxes. Given we are not a significant US taxpayer due to our current tax attributes, we include estimated taxes at our current statutory tax rate of approximately 26%. Net assets is total assets less goodwill, and intangible assets, net and all non-interest bearing liabilities. Denominator is calculated as a four quarter average for annual metrics and two quarter average for quarterly metrics.

The following table provides unaudited reconciliations of Return on Invested Capital, which is calculated using metrics from our Balance Sheets and Statements of Operations. Average Invested Capital and Adjusted EBITDA related to our former UK Storage Solutions segment have been excluded prospectively from January 1, 2023.
