In light of this transaction, WSC intends to host its Investor Day later this year after the transaction closes and will provide additional details in due course.

Brad Soultz, Chief Executive Officer of WillScot Mobile Mini, commented, “2023 was a record year for WillScot Mobile Mini across our financial metrics. We built our platform to deliver consistent compound returns irrespective of market conditions, which is evident in our results as we enter 2024. We eclipsed our $1 billion Adjusted EBITDA milestone faster than we expected, generated $577 million of Free Cash Flow, reduced common shares outstanding to 190 million, and grew earnings per share from continuing operations by 35% year-over-year. And we delivered these results while making the right investments to position our platform for the long-term benefit of our customers, employees, and shareholders. In 2023, we upgraded our CRM system, which gives us the most scalable technology platform in the industry. We divested the UK Storage segment and reinvested those proceeds here in North America. And we extended our unmatched offering of space solutions with the addition of industry-leading platforms in climate-controlled storage and clearspan structures.”

Soultz continued, “Heading into 2024, our strategy is unchanged, and we will continue to invest in capabilities to differentiate our offering. We have immediate and significant tailwinds across rates, Value-Added Products (VAPS), margins, and M&A. We are making new investments in both human capital and digital tools, leveraging a powerful combination of local market intimacy and scale, to create an unparalleled customer experience. And our innovation pipeline has never been stronger, as we commercialize new and creative temporary space solutions for our customers.”

Soultz concluded, “Our pending acquisition of McGrath RentCorp (NASDAQ: MGRC) will accelerate our growth as we extend our differentiated value proposition for the benefit of all of our stakeholders. And while we work to close that transaction, we do so knowing that it complements the extraordinary opportunity set that we are already executing within our platform. Thank you to our team for delivering the strongest year in our Company’s history. I am confident that our track record of growth and execution will continue in 2024 and beyond.”

Fourth Quarter 2023 and Full Year 2023 Results²

Tim Boswell, President and Chief Financial Officer, commented, “2023 was a record year financially across all metrics, and we are carrying momentum into 2024 to drive another year of record performance. And we are delivering these outstanding results despite mixed commercial and market indicators in 2023, which is a testament to the strength of our business model and strategy. Across the portfolio, rental rates generally offset volume declines, which were consistent with the contraction of non-residential construction start square footage and retail demand throughout the year relative to record 2022 levels. Through the middle of February, modular unit VAPS contribution inflected to historical highs and VAPS penetration in storage units continued to build. In the same time frame, modular activations and net orders were up year-over-year, while storage activations were in line with non-residential start square footage. Margins continue to be a tailwind, with Adjusted EBITDA margin of 44.9% up 360 basis points for the year, and with in-flight initiatives across all revenue streams supporting margins as we head into 2024.”

Boswell continued, “Our capital allocation framework remains consistent, and our allocation process remains disciplined and demand-driven. We generated $577 million of Free Cash Flow, and see a clear path to $700 million of Free Cash Flow irrespective of the recently announced McGrath acquisition. We invested $185 million of Net Capex in 2023, which approximates maintenance levels given our lower fleet utilization. We invested $562 million in M&A, expanding our offering and total addressable market. And we invested $811 million in share repurchases, resulting in an 8.6% reduction in our share count over the last 12 months. Together, the consistent application of this framework over time drove Return on Invested Capital of 18% and 35% growth in earnings per share from continuing operations in 2023.”

Boswell concluded, “At the midpoint of our 2024 guidance, we expect revenue to grow by 8% to $2,560 million and Adjusted EBITDA to grow by 10% to $1,163 million, with margins up approximately 50 basis points, resulting in yet another record year financially. Our track record and outlook are the predictable result of a strategy constructed to deliver consistent growth and returns over time. And heading into 2024, our organic and inorganic investments are extending that horizon appreciably.”

Capitalization and Liquidity Update²

As of and for the three months ended December 31, 2023, except where noted:

• Generated $166 million of Free Cash Flow in the fourth quarter, up 35% year-over-year.
• Invested $76 million of capital in one acquisition during the quarter, with $562 million invested in the last 12 months.
• Increased excess availability to approximately $1.2 billion under our asset backed revolving credit facility.
• Weighted average pre-tax interest rate, inclusive of 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 $212 million. Our debt structure is approximately 77% / 23% 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 $1,061 million, which is inside our target range of 3.0x to 3.5x.
• Repurchased 3.5 million shares of Common Stock for $136 million in the quarter, contributing to a 8.6% reduction in our share count over the last 12 months. We paused repurchasing shares in the middle of Q4 2023 as acquisition discussions advanced with McGrath RentCorp.

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 December 31, 2023 versus common shares outstanding as of December 31, 2022.
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.
6 – During the first quarter of 2023, the ground level office business within the Modular segment was transferred to the Storage segment, and associated revenues, expenses, and operating metrics were transferred to the Storage segment. All periods presented have been retrospectively revised to reflect this change within the Modular and Storage segments. See further discussion within the Unaudited Segment Operating Data tables included at the end of this press release.

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 net assets. 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 Company and McGrath’s respective boards of directors. 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 the second quarter of 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 WSI, in accordance with the terms of the Commitment Letter, (i) an $875 million eight year senior secured bridge credit facility, (ii) an $875 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 $4.45 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

Unaudited Segment Operating Data

The Company operates in two reportable segments: Modular and Storage. Modular represents the activities of the North American modular business, excluding ground level offices, which were transferred to the Storage segment during the first quarter of 2023. Storage represents the activities of the North American portable storage and ground level office business. All periods presented have been retrospectively revised to reflect this change within the Modular and Storage segments. Effective January 1, 2023, we transferred approximately 6,000 Ground Level Office (GLO) modular products from the Modular Solutions segment to our Storage Solutions segment. We transferred these legacy WillScot GLOs to the Storage Solutions segment because they are modified container products that can be operated more efficiently on the legacy Mobile Mini branch and logistics infrastructure. The adjustment transferred approximately $49.8 million of revenue and $20.8 million of Adjusted EBITDA on an annualized basis from Modular Solutions to Storage Solutions. We recast historical segment financial results and operating key performance indicators (KPIs) to reflect this transfer.

For the three months ended December 31, 2022, this transfer resulted in approximately $12.9 million of revenue, $7.6 million of gross profit, and $5.9 million of Adjusted EBITDA being transferred from the Modular segment to the Storage segment. For the year ended December 31, 2022, this resulted in approximately $49.8 million of revenue, $28.5 million of gross profit, and $20.8 million of Adjusted EBITDA being transferred from the Modular segment to the Storage segment. As part of the transfer, we adjusted the average monthly rental rate for modular units (Ground Level Offices) in the Storage segment to incorporate Value-Added Products specifically applicable to Ground Level Offices.

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 segment performance on Adjusted EBITDA, a non-GAAP measure that excludes certain items as described below. We believe that evaluating segment 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 by segment to assist in the assessment of the operational performance of each operating segment. We consider Adjusted EBITDA to be the more important metric because it more fully captures the business performance of the segments, 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

Adjusted EBITDA is a non-GAAP measure defined as net income (loss) before income tax expense (benefit), net interest (income) expense, depreciation and amortization adjusted for certain items 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.
• Gains and losses resulting from changes in fair value and extinguishment of common stock warrant liabilities.
• 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 tables provide unaudited reconciliations of Income before income tax to Adjusted EBITDA for the ground level office segment adjustment:

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 unaudited reconciliations of Adjusted EBITDA 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 Tank and Pump segment through September 30, 2022 and 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 including discontinued operations includes amounts for the former Tank and Pump segment through September 30, 2022 and 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 net assets. 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% effective in 2023. 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 Tank and Pump segment and former UK Storage Solutions segment have been excluded prospectively from July 1, 2022 and January 1, 2023, respectively, and prior periods have not been adjusted.
