PHOENIX, Feb. 25, 2021 (GLOBE NEWSWIRE) -- WillScot Mobile Mini Holdings Corp. (“WillScot Mobile Mini Holdings” or the “Company”) (Nasdaq: WSC), the North American leader in turnkey modular space and portable storage solutions, today announced fourth quarter and full year 2020 financial results and provided an update on merger integration activities, the current market environment and its 2021 outlook.

On July 1, 2020, Williams Scotsman, Inc. closed the merger with Mobile Mini, Inc. (the "Merger") and assumed the name WillScot Mobile Mini Holdings Corp. (Nasdaq: WSC). 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 financing transactions had occurred on January 1, 2019, which we believe is 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.

WillScot Mobile Mini Holdings’ Financial Highlights¹
Highlights of Fourth Quarter Results

• Total revenues of $437.6 million increased by $159.6 million relative to prior year, or 57.4%, driven by the addition of Mobile Mini's revenues to our consolidated results, upon closing of the Merger on July 1, 2020.
  
  °  Modular space monthly rental rates in the NA Modular segment increased by 12.9% year over year.

Management Commentary¹

"Our WillScot Mobile Mini team concluded a transformational year and set the foundation for an exciting new chapter of growth and value creation, despite unprecedented operating challenges," said Brad Soultz, Chief Executive Officer of WillScot Mobile Mini Holdings. "Our portfolio continued to demonstrate its resilience in the fourth quarter as we grew our leasing and services revenue both sequentially and versus prior year, driven by 12.9% average rental rate growth in our NA Modular segment, and impressive rates and volumes in our Storage segments. New order rates, pricing, and value-added products penetration are all trending positively heading into 2021 across our diversified segments and end markets."

"As we progress through the integration, we are developing an expanding portfolio of growth initiatives, which will propel the business for years to come. Some, such as continued price performance and penetration of value-added services are well underway, whereas others such as cross-selling and implementation of operating best practices across our segments are in their infancy and will develop in 2021. We are on track to complete our system migration in the first half of the year, as planned, which will enable further synergies. And, we also started developing our Environmental, Social, and Governance (ESG) roadmap, which will build on the values shared across our organization, while highlighting the inherently sustainable value proposition in our temporary modular and storage solutions."

Soultz continued, “I am proud of the entire team for bringing 2020 across the finish line and am excited for the next phase of our journey.  As our teams have coalesced, Kelly Williams has announced his intention to transition from WillScot Mobile Mini effective July 31, 2021.  I could not have asked for a better partner than Kelly in planning and executing our integration, where he has played an instrumental role. On behalf of the entire WillScot Mobile Mini Holdings Board of Directors, I want to thank him for contributions that will drive years of value creation for our stakeholders. I am also incredibly excited about the broader management structure that we have in place to drive our long-term goals. We are positioned to effectively harness the combined operating expertise of the legacy WillScot and Mobile Mini organizations as we journey forward."

Chief Financial Officer of WillScot Mobile Mini, Tim Boswell, noted that "With the integration ongoing, we delivered another outstanding quarter with acceleration across our key financial metrics. Free cash flow in the fourth quarter increased by $44 million year over year to $87 million. This represents a 20% free cash flow margin in the quarter and shows obvious progression towards the $500 million run-rate free cash flow milestone that we identified one year ago when we were developing our vision for WillScot Mobile Mini. Steady execution of our leasing KPIs, execution of synergies and operating efficiencies, and disciplined capital allocation are all working together to drive free cash flow and returns. We have a high degree of visibility into continued improvements, given our unique business model. Pro forma leverage decreased to 3.8x in the fourth quarter and is well on track to be within our target range of 3.0x to 3.5x by the end of 2021. We also used our share repurchase authorization opportunistically to buy back $35 million of outstanding warrants and share equivalents. Our 2021 guidance is supported by growth initiatives that are within our control and will put us on an exciting trajectory for 2022 and beyond."

Fourth Quarter 2020 Results¹

Total revenues increased 57.4% to $437.6 million, while leasing revenues increased 67.6% versus the prior year quarter driven primarily by the addition of Mobile Mini's revenues to our consolidated results.

• Average modular space units on rent increased 21,780 units, or 24.2%, and average portable storage units on rent increased 143,594 units, both driven by the Mobile Mini Merger.
• Average modular space monthly rental rate increased $29, or 4.5% to $670 driven by a $83, or 12.9% increase in the NA Modular segment, offset by the dilutive impact of lower rates due to mix on the Mobile Mini modular space units.
• Average portable storage monthly rental rate increased $18, or 15.3% to $136 driven by the accretive impact of higher rates from the Mobile Mini portable storage fleet.
  
  
• NA Modular segment revenue decreased 2.7% to $270.6 million, primarily driven by a $12.9 million decline in new unit sales revenues. However, leasing revenues increased $6.9 million, or 3.6% due to continued growth of pricing and value added products:
  
  °  NA Modular space average monthly rental rate of $724 increased 12.9% year over year, representing a continuation of the long-term price optimization and VAPS penetration opportunities across our portfolio.
  
  °  Average NA modular space units on rent decreased 4,002, or 4.4%, year over year, however, only dropped 0.5% sequentially from Q3 into Q4 to 86,011, which compares to a 1.3% drop from Q3 to Q4 in 2019 providing clear evidence of stabilization across our end markets.

Adjusted EBITDA of $179.7 million increased $81.5 million, or 83.0% year over year. Of this increase, $72.2 million was driven by the addition of Mobile Mini to our consolidated results, with the remainder driven by strong organic growth in the NA Modular segment.

• Adjusted EBITDA in our NA Modular segment increased $9.3 million, or 9.5% to $107.5 million primarily driven by increases in leasing and services gross profit excluding depreciation of $16.8 million, or 11.6%, driven by increased pricing and VAPS, as well as approximately $9.5 million of variable cost savings.
• Consolidated Adjusted EBITDA Margin was 41.1% in the fourth quarter and increased 580 bps versus prior year driven by a 440 bps increase in the NA Modular segment, as well as the addition of the higher margin Mobile Mini operations in Q3 2020. Within the NA Modular segment, margin expansion was driven by a 490 bps improvement in leasing and services gross profit margin excluding depreciation due to variable cost reductions and a higher mix of more profitable leasing revenues, partially offset by increased selling, general, and administrative costs. During the quarter, we realized year over year incremental synergy savings in the NA Modular segment of $5.1 million related to previous acquisitions.

Net income of $46.5 million for the three months ended December 31, 2020 was up $37.6 million versus prior year.

Free Cash Flow increased by $43.7 million year over year to $87.4 million, representing a 20% free cash flow margin.

Full Year 2020 Results¹

Total revenues increased $303.9 million, or 28.6%, year over year to $1,367.6 million, driven by a 32.3% increase in leasing and services revenue due to improved pricing and VAPS penetration in our NA Modular segment, and increased volumes due to the addition of Mobile Mini's revenues to our consolidated results following the Merger on July 1, 2020.

• Consolidated average modular space monthly rental rates increased $44, or 7.2% year over year driven by a $71, or 11.6%, increase in the NA Modular segment, partially offset by the dilutive impact of lower rates due to mix on the Mobile Mini modular space units.
• Consolidated average portable storage monthly rental rates increased $12, or 10.0% versus prior year driven by the accretive impact of higher rates from the Mobile Mini portable storage fleet.
• Average modular space and portable storage units on rent increased 8.6% and 398.6% year over year, respectively, driven by the Mobile Mini Merger, partially offset by reductions in new project starts in the second and third quarters, following the onset of the COVID-19 pandemic.
• NA Modular segment revenue decreased 1.2% to $1,051.2 million, primarily driven by a $26.6 million decline in new and rental unit sales revenues and a $12.0 million decrease in delivery and installation revenues, primarily due to demand disruptions in the second and third quarters. However, leasing revenues increased $26.1 million, or 3.5% due to continued growth of pricing and value added products:
  
  °  Modular space average monthly rental rate of $685 increased 11.6% year over year, representing a continuation of the long-term price optimization and VAPS penetration opportunities across our portfolio.
  
  °  Average modular space units on rent decreased 4,808, or 5.2%, year over year, however, only dropped 0.5% sequentially from Q3 into Q4 to 86,011, which compares to a 1.3% drop from Q3 to Q4 in 2019.

Adjusted EBITDA of $530.3 million, represented a $173.8 million, or 48.8%, increase year over year. Of this increase, $135.5 million was driven by the addition of Mobile Mini to our consolidated results, and the remainder was driven by strong organic growth in our NA Modular segment of $38.3 million, or 10.7%.

Adjusted EBITDA margin expanded 530 bps year over year to 38.8% and with strong margin expansion across all four operating segments. The margin expansion was driven by strong pricing and value-added products growth, a revenue mix shift weighted towards higher margin leasing revenues, and proactive cost reductions implemented in Q2 and maintained through Q4 to adjust for demand disruptions due to the COVID pandemic.

Net income of $71.9 million for the year ended December 31, 2020 was up $83.4 million versus prior year and included a $42.4 million loss on extinguishment of debt related to our recent refinancing activities and $93.8 million of discrete costs expensed in the period related to transaction and integration activities, partly offset by a $51.5 million non-cash income tax benefit.

Free Cash Flow increased by $142.3 million year over year to $162.3 million.

Capitalization and Liquidity Update^1,3

Through a series of strategic transactions leading up to and immediately following the Merger, we refinanced and optimized all of WillScot's and Mobile Mini’s pre-existing debt and put in place a robust capital structure that we believe will support the business for years to come.

As of December 31, 2020

• We generated $87.4 million of free cash flow in the fourth quarter and are highly liquid and cash generative heading into 2021.
• We had over $1 billion of excess availability under the asset-based revolving credit facility, which combined with strong cash generation from operations and a flexible covenant structure, give us ample liquidity with which to operate the business.
• Our weighted average interest rate is approximately 4.1% and annual cash interest expense based on the current debt structure is approximately $104 million.
• We have no debt maturities prior to 2025.
• We reduced leverage to 3.8x our pro forma last-twelve-months Adjusted EBITDA of $646.5 million and are on a rapid deleveraging trajectory.

2021 Outlook^{1, 2, 3}

This guidance is subject to risks and uncertainties, including those described in "Forward-Looking Statements" below. The 2021 guidance includes:

1 - Adjusted EBITDA, Adjusted EBITDA Margin, and Free Cash Flow 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") is included at the end of this press release.
2 - Information reconciling forward-looking Adjusted EBITDA and Net CAPEX to GAAP financial measures is unavailable to the Company without unreasonable effort and therefore no reconciliation to the most comparable GAAP measures is provided.
3 - Net CAPEX is a non-GAAP financial measure. Please see the non-GAAP reconciliation 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, Free Cash Flow, pro forma revenue, 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, 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. 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. 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. However, 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 press release (except as explained below), see “Reconciliation of Non-GAAP Financial Measures" included in this press release.

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.

Reconciliation of Non-GAAP Financial Measures

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 in the reconciliation of our consolidated net income (loss) to Adjusted EBITDA reconciliation below. We believe that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic 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 meet future debt service obligations and working capital requirements.

Adjusted EBITDA

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. Substantially all such currency gains (losses) are unrealized and attributable to financings due to and from affiliated companies.
• 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 and lease 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 includes 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 Net income (loss) to Adjusted EBITDA.

Consolidated Adjusted EBITDA

(a) In connection with the ModSpace acquisition, the Company incurred bridge financing fees and upfront commitment fees of $20.5 million, included within interest expense, during the year ended December 31, 2018.
(b) Other expense includes consulting expenses related to one-time projects, financing costs not classified as interest expense and gains and losses on the disposal of property, plant and equipment.

Pro Forma Adjusted EBITDA

The unaudited table below provides a reconciliation of pro forma net income (loss) to pro forma Adjusted EBITDA and incorporates all pro forma adjustments made to present the historical consolidated statements of operations of WillScot Mobile Mini Holdings, giving effect to the following items as if they had occurred on January 1, 2019:

1. the Merger with Mobile Mini;
2. borrowings under the Company’s 2025 Secured Notes and the 2020 ABL Facility;
3. extinguishment of the Mobile Mini line of credit and senior notes assumed in the Merger and subsequently repaid;
4. repayment of the 2017 ABL Facility and the 2022 Senior Notes repaid contemporaneously with the Merger;
5. the transaction costs incurred in connection with the Merger; and
6. elimination of non-controlling interest in connection with the Sapphire Exchange as contemplated by the Merger.

Adjusted EBITDA Margin Non-GAAP Reconciliation

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 tables provide unaudited reconciliations of Adjusted EBITDA Margin.

Pro Forma Adjusted EBITDA Margin Non-GAAP Reconciliation

The following tables provide unaudited reconciliations of Pro Forma Adjusted EBITDA Margin.

Free Cash Flow

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. Management believes that the presentation of Free Cash Flow provides useful information to investors regarding our results of operations because it provides useful additional information concerning cash flow available to meet future debt service obligations and working capital requirements.

The following table provides unaudited reconciliations of net cash provided by operating activities to Free Cash Flow.

Adjusted Gross Profit and Adjusted Gross Profit Percentage

We define Adjusted Gross Profit as gross profit plus depreciation on rental equipment. Adjusted Gross Profit Percentage is defined as Adjusted Gross Profit divided by revenue. Adjusted Gross Profit and Percentage are not measurements of our financial performance under GAAP and should not be considered as an alternative to gross profit, gross profit percentage, or other performance measures derived in accordance with GAAP. In addition, our measurement of Adjusted Gross Profit and Adjusted Gross Profit Percentage may not be comparable to similarly titled measures of other companies. Our management believes that the presentation of Adjusted Gross Profit and Adjusted Gross Profit Percentage provides useful information to investors regarding our results of operations because it assists in analyzing the performance of our business.

The following table provides unaudited reconciliations of gross profit to Adjusted Gross Profit and Adjusted Gross Profit Percentage.

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 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.

The following table provides unaudited reconciliations of Net CAPEX:
