Our lease revenue is highly predictable due to its recurring nature and the underlying stability and diversification of our lease portfolio.

However, given that our customers value flexibility, they consistently extend their leases or renew on a month-to-month basis such that the average effective duration of our lease portfolio excluding seasonal portable storage units is nearly 30 months.

Furthermore, given that our customers value flexibility, they consistently extend their leases or renew on a month-to-month basis such that the average effective duration of our modular space and portable storage lease portfolio, excluding seasonal portable storage units, is nearly 31 months.

We complement our core leasing business by selling both new and used units, allowing us to leverage scale, achieve purchasing benefits and redeploy capital employed in our lease fleet.

Our customers operate in a diversified set of end markets, including construction, commercial and industrial, retail and wholesale trade, education, energy and natural resources, government, and healthcare.

Core to our operating model is the ability to redeploy standardized assets across end markets, as we did in 2020 to service emerging demand in the healthcare and government sectors related to COVID-19, as well as expanded space requirements related to social distancing.

We track several market leading indicators including those related to our two largest end markets, the commercial and industrial segment and the construction segment, which together accounted for over 85% of our revenues for the three months ended September 30, 2021.

Our customers operate in a diversified set of end markets, including construction, commercial and industrial, retail and wholesale trade, energy and natural resources, education, government and institutions, and healthcare.

Core to our operating model is the ability to redeploy standardized assets across end markets, as we did in 2020 and 2021 to service emerging demand in the healthcare and government sectors related to COVID-19, as well as expanded space requirements related to social distancing.

We track several market leading indicators in order to predict demand, including those related to our two largest end markets, the commercial and industrial segment and the construction segment, which collectively accounted for approximately 46% and 41% of our revenues, respectively, for the three months ended March 31, 2022.

We remain focused on our core priorities of growing leasing revenues by increasing units on rent, both organically and through our consolidation strategy, delivering “Ready to Work” solutions to our customers with value added products and services ("VAPS"), and on continually improving the overall customer experience.

Significant Developments

Mobile Mini Merger

On July 1, 2020, we closed the Merger 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.

We believe that the Merger is resulting in strategic and financial benefits by combining the two industry leaders in the complementary modular space and portable storage solutions markets.

As part of the Merger, we planned to integrate the two companies' customer relationship management, operating, and financial systems.

A significant portion of these efforts to date had been focused on the conversion of the combined company onto a single enterprise resource planning system, which was successfully completed during the second quarter of 2021.

Other Acquisitions

On September 17, 2021, the Company acquired certain assets and liabilities of three companies in the United States that focus primarily in the portable storage solutions market for $56.3 million in cash.

The primary assets acquired included approximately 11,000 storage units and 400 modular units, the majority of which were on rent.

See Note 2 to the condensed consolidated financial statements for further discussion.

We continue to manage a pipeline of potential acquisition targets and anticipate that mergers and acquisitions will be a significant portion of our capital allocation priorities.

Reportable Segments

Following the Merger, we operate in four reporting segments:

NA Modular, NA Storage, UK Storage, and Tank and Pump.

Prior to the Merger, WillScot had two reporting segments, US Modular and Other North America Modular.

These two segments were combined to create the NA Modular segment, which represents the legacy WillScot operations.

The other segments, NA Storage, UK Storage, and Tank and Pump, align to the legacy operations and segments reported by Mobile Mini.

The reporting segments are aligned with how we operate and analyze our business results.

Financing Activities

On March 26, 2021, we redeemed $65.0 million of our 6.125% senior secured notes due 2025 (the “2025 Secured Notes”) at a redemption price of 103.0%, plus accrued and unpaid interest.

This repayment was funded by internally generated cash flow and lower cost borrowings under the 2020 ABL facility.

Upon redemption in the first quarter of 2021, we recorded a loss on extinguishment of debt in the condensed consolidated statement of operations of $3.2 million comprised of a redemption premium of $1.9 million and write off of unamortized deferred financing fees of $1.3 million.

On June 16, 2021, we redeemed an additional $58.5 million of our 2025 Secured Notes at a redemption price of 103.0%, plus accrued and unpaid interest.

This repayment was funded by internally generated cash flow and lower cost borrowings under the 2020 ABL facility.

Upon redemption in the second quarter of 2021, we recorded a loss on extinguishment of debt in the condensed consolidated statement of operations of $2.8 million comprised of a redemption premium of $1.8 million and write off of unamortized deferred financing fees of $1.0 million.

Asset Acquisitions

During the first quarter of 2022, we acquired certain assets and liabilities, which consisted primarily of approximately 400 blast resistant modular units.

When combined with other recent acquisitions over the past three quarters, we have acquired assets and liabilities from eight regional and local storage and modular companies, consisting primarily of 15,700 storage units and 6,200 modular units.

Share and Warrant Repurchases

On March 1, 2021, we repurchased and cancelled 2,750,000 shares of our Common Stock directly from Sapphire Holding S.à r.l.

(“Sapphire Holdings”), our largest shareholder at that time, which is controlled by TDR Capital LLP (“TDR Capital”), for $73.7 million.

On June 29, 2021, we repurchased and cancelled an additional 3,900,000 shares of our Common Stock directly from Sapphire Holdings for $108.2 million.

On September 9, 2021, we repurchased and cancelled an additional 2,379,839 shares of our Common Stock directly from Sapphire Holdings for $67.1 million.

During the nine months ended September 30, 2021, we repurchased and cancelled 3,055,000 2015 Private Warrants for $25.5 million.

In addition, during the nine months ended September 30, 2021, 9,655,000 2015 Private Warrants were exercised on a cashless basis, resulting in the issuance of 2,939,898 shares of Common Stock.

As a result of these transactions, no 2015 Private Warrants were outstanding as of September 30, 2021.

At September 30, 2021, 6,525,736 of the 2018 Warrants were outstanding.

During the nine months ended September 30, 2021, we repurchased a total of 11,656,552 shares of Common Stock and stock equivalents for $322.6 million, including the shares repurchased from Sapphire Holdings and all repurchased warrants.

As of September 30, 2021, we had $142.2 million remaining of a $500.0 million share repurchase authorization under our stock repurchase program.

During the three months ended March 31, 2022, we repurchased and cancelled 11,032 of the 2018 Warrants for $0.2 million.

At March 31, 2022, 3,137,762 of the 2018 Warrants were outstanding.

During the three months ended March 31, 2022, we repurchased a total of 2,070,054 shares of Common Stock and stock equivalents for $77.4 million , including the repurchased warrants.

As of March 31, 2022, we had $879.3 million remaining of a $1 billion share repurchase authorization under our stock repurchase program.

Given the predictability of our free cash flow, we believe that repurchases will be a reoccurring capital allocation priority.

In October of 2021, the Company's Board of Directors replaced the existing share repurchase program with a new share repurchase program that authorizes the Company to repurchase up to $1.0 billion of its outstanding shares of Common Stock and equivalents.

COVID-19 Impact on Business

Since the outbreak of COVID-19 was designated as a global pandemic by the World Health Organization (the “WHO”) in March 2020, our operations have generally continued to operate normally with additional safety protocols in place as we have been considered an essential business in most jurisdictions.

The global macroeconomic backdrop and impact on our end markets has evolved rapidly since the beginning of 2020.

However, overall our lease portfolio and financial results have proven to be durable and predictable despite the severity of the economic contraction in 2020 and the current expansion in 2021.

On a pro forma basis, our deliveries were down 25% in the second quarter of 2020 year over year and 13% in the third quarter of 2020 year over year due to COVID-19 related economic contraction in our largest geographic markets.

This reduced delivery demand slowed the growth of our leasing revenues as well as our delivery and installation revenues.

However, we successfully implemented significant variable cost and capital expenditure reductions to help offset the financial impact of the temporarily reduced activity levels.

Importantly, due to our long lease durations, the majority of our gross profit in any given period is from units already out on rent.

This gives us significant forward visibility into our future cash flows, which allows us to plan ahead and adjust our capital expenditures and cost structure for varying demand levels.

As expected, our portfolio of units already out on rent at the onset of the pandemic was resilient and largely unimpacted, despite the unprecedented swings in economic activity in 2020.

Activity levels in the fourth quarter of 2020 and the first half of 2021 stabilized, and our volume of new lease activations grew significantly in the second quarter of 2021 as economic activity rebounded sharply with modular deliveries across our NA Modular and NA Storage segments up a combined 9% over 2020 levels and storage product deliveries across these two segments up a combined 39% over 2020 levels and on par with 2019 pro forma activity levels.

This recovery continued in the third quarter of 2021 and for the three months ended September 30, 2021, both modular and storage product deliveries across our NA Modular and NA Storage segments were up a combined 6% over 2020 levels.

Overall, while new lease activation volumes over the past seven quarters were impacted in line with the swings in economic activity, our lease revenue streams were stable and predictable and remain on an attractive upward long-term trajectory, which is a direct reflection of the diversification in our end markets, our long lease durations, and the success of the organic growth initiatives that we are executing.

Third Quarter Highlights

For the three months ended September 30, 2021, key drivers of our financial performance included:

• Total revenues increased by $73.3 million, or 17.6%.

Leasing revenue increased $63.3 million, or 21.1%, delivery and installation revenue increased $15.0 million, or 17.7%, rental unit sales decreased $1.6 million, or 12.1%, and new sales revenue decreased $3.5 million, or 18.0%.

First Quarter Highlights

For the three months ended March 31, 2022, as compared to the three months ended March 31, 2021 unless otherwise noted, key drivers of our financial performance included:

• Total revenues increased by $83.6 million, or 19.7%, attributable to organic revenue growth levers in the business and due to the impact of acquisitions.

Leasing revenue increased $77.5 million, or 24.5%, and delivery and installation revenue increased $16.8 million, or 20.1%.

These increases were offset by decreased sales;

rental unit sales decreased $6.4 million, or 42.1%, and new unit sales revenue decreased $4.4 million, or 40.0%.

We estimate that recent acquisitions contributed approximately $12.0 million to total revenues for three months ended March 31, 2022.

Key leasing revenue drivers include:

– Average portable storage units on rent increased 19,408 units, or 13.5%, and average modular space units on rent decreased 1,395 units, or 1.3%.

The increase in average portable storage units on rent was driven by significant increases in delivery activity during 2021 as economic activity rebounded versus 2020 more quickly across portable storage units than modular space units.

– Average portable storage units on rent increased 34,877 units, or 24.0%, and average modular space units on rent increased 1,670 units, or 1.5%.

Approximately 50% of the increase in total average units on rent was driven by increases in organic delivery activity and lower return activity during 2021 and into the first quarter of 2022 as economic activity rebounded versus 2020 and the other 50% was driven by units on rent acquired as a result of recent acquisitions.

– Average modular space monthly rental rate increased $123, or 18.1%, to $802 driven by strong pricing performance across all relevant segments.

3 unchanged sentences

Average utilization for modular space units decreased 140 basis points ("bps") to 68.9%.

• NA Modular segment revenue, which represents 61.0% of consolidated revenue for the three months ended September 30, 2021, increased $31.2 million, or 11.6%, to $299.1 million.

• NA Modular segment revenue, which represents 58.9% of consolidated revenue for the three months ended March 31, 2022, increased $33.5 million, or 12.6%, to $299.7 million.

The increase was driven by our core leasing revenue, which grew $33.4 million, or 16.7%, due to continued growth of pricing and value added products.

Delivery and installation revenues increased $5.9 million, or 11.3%, driven by increased demand for new project deliveries as compared to 2020, which was significantly impacted by slowdowns associated with COVID-19.

Delivery and installation revenues increased $6.9 million, or 14.2%, driven by increased pricing on new deliveries and returns as compared to 2021.

The increases to leasing revenue and delivery and installation revenues were partially offset by declines in revenues for portable storage units as the result of transitioning the majority of the portable storage product business within the NA Modular segment to the NA Storage segment.

Rental unit sales decreased $4.2 million, or 40.4%, and new unit sales decreased $2.7 million, or 36.0%.

NA Modular revenue drivers for the three months ended September 30, 2021 included:

NA Modular revenue drivers for the three months ended March 31, 2022 included:

– Modular space average monthly rental rate of $884, increased 19.9% 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 2,182, or 2.5%, year over year driven by lower deliveries during 2020 as a result of the COVID-19 pandemic.

• NA Storage segment revenue, which represents 27.3% of consolidated revenue for the three months ended September 30, 2021, increased $29.4 million, or 28.1%, to $133.9 million.

The increase was driven by our core leasing revenue, which grew $24.2 million, or 31.4%, due to increased units on rent driven by significant increases in delivery activity during 2021 as economic activity rebounded versus 2020, and increased pricing.

Delivery and installation revenues increased $7.4 million, or 35.4%, driven by increased demand for new project deliveries as compared to 2020, which was significantly impacted by slowdowns associated with COVID-19.

The increases to leasing revenue and delivery and installation revenues in the NA Storage segment were also impacted as the result of transitioning the majority of the portable storage product business within the NA Modular segment to the NA Storage segment.

Rental unit sales increased $0.3 million, or 10.7%, and new unit sales decreased $2.5 million, or 65.8%.

NA Storage revenue drivers for the three months ended September 30, 2021 included:

– Average modular space units on rent increased 212, or 0.3%, year over year driven primarily by units on rent acquired as a result of recent acquisitions.

Sequentially from December 31, 2021, modular space units on rent increased by approximately 1,800 units, or 2.1%.

Excluding units acquired from acquisitions during the quarter, sequential modular space units on rent from December 31, 2021 increased by approximately 1,400 units, or 1.7%.

– Average modular space monthly utilization decreased 60 bps to 67.0% for the three months ended March 31, 2022, as compared to the three months ended March 31, 2021.

Sequentially from the fourth quarter 2021, average modular utilization decreased 50 bps, however end of period utilization increased over 100 bps from December 31, 2021 to March 31, 2022.

• NA Storage segment revenue, which represents 29.8% of consolidated revenue for the three months ended March 31, 2022, increased $43.7 million, or 40.5%, to $151.5 million.

The increase was driven by our core leasing revenue, which grew $38.2 million, or 47.5%, due to increased units on rent driven by significant increases in delivery activity during 2021 and into the first quarter of 2022 as economic activity rebounded versus 2020, recent acquisition activity, and increased pricing.

Delivery and installation revenues increased $8.5 million, or 39.7%, driven by increased demand for new project deliveries, and by increased pricing on new deliveries and returns as compared to 2021.

The increases to leasing revenue and delivery and installation revenues in the NA Storage segment were also impacted

as the result of transitioning the majority of the portable storage product business within the NA Modular segment to the NA Storage segment.

Rental unit sales decreased $1.7 million, or 44.7%, and new unit sales decreased $1.3 million, or 59.1%.

NA Storage revenue drivers for the three months ended March 31, 2022 included:

• Portable storage average monthly rental rate of $166, increased 12.2% year over year as a result of our price management tools and processes, further supported by tight supply on portable storage containers in the markets in which we operate.

Modular space average monthly rental rate of $594, increased 11.0% year over year as a result of price optimization and early benefits from increased VAPS penetration opportunities.

• Average portable storage units on rent increased 31,902, or 30.3%, year over year driven by significant increases in delivery activity during 2021 as economic activity rebounded versus 2020.

NA Storage portable storage units on rent also increased as a result of the transitioning of the majority of the portable storage product business within the NA Modular segment to the NA Storage segment during the third quarter, which represented the transfer of approximately 12,000 units on rent.

• Average portable storage units on rent increased 46,516, or 44.0%, year over year.

Increases in organic activity in 2021 and the first quarter of 2022 drove an increase to average portable storage units on rent of approximately 18% or 19,000 units on rent.

Of the remaining increase, approximately 15,500 units on rent was driven by units acquired from recent acquisitions, and approximately 12,000 units on rent was driven by transitioning the portable storage product business within the NA Modular segment to the NA Storage segment, which occurred in the third quarter of 2021.

Combined, average portable storage units on rent for the NA Storage and NA Modular segments increased approximately 32,076 units, or 26.6%.

Given the timing of acquisitions during the quarter, acquisition units did not have a material impact on average units on rent.

Average modular space units on rent were essentially flat year over year.

• Average portable storage monthly utilization increased 980 bps to 83.2% for the three months ended September 30, 2021, as compared to the three months ended September 30, 2020.

Other Non-GAAP Financial Data and Reconciliations

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 the 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.

Purchases of rental equipment and refurbishments increased $4.7 million, or 146.9%, to $7.9 million for the three months ended March 31, 2022 from $3.2 million for the three months ended March 31, 2021.

Net CAPEX increased $4.6 million, or 143.8%, to $7.8 million.

These increases were driven primarily by increased purchases of rental fleet during the period to support organic growth given high utilization, as well as by reduced proceeds from sales of rental fleet given high utilization.

Reconciliation of Non-GAAP Financial Measures

In addition to using GAAP financial measurements, we use certain non-GAAP financial measures to evaluate our operating results.

As such, we include in this Quarterly Report on Form 10-Q reconciliations of non-GAAP financial measures to their most directly comparable GAAP financial measures.

Set forth below are definitions and reconciliations to the nearest comparable GAAP measure of certain non-GAAP financial measures used in this Quarterly Report on Form 10-Q along with descriptions of why we believe these measures provide useful information to investors as well as a description of the limitations of these measures.

Each of these non-GAAP financial measures has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for analysis of, results reported under GAAP.

Our measurements of these metrics may not be comparable to similarly titled measures of other companies.

Adjusted EBITDA

We define EBITDA as net income (loss) plus interest expense, income tax expense (benefit), depreciation and amortization.

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:

Leasing revenues increased $42.6 million compared to the prior year.

Modular space average units on rent increased 3.1% and average modular space monthly rental rates increased 16.8% year-over-year driven primarily by increased pricing on new deliveries.

Portable storage units on rent increased 14.0% and average portable storage monthly rental rates increased 4.8% year-over-year also driven primarily by increased pricing on new deliveries.

Delivery and installation revenues increased $14.0 million year-over-year as delivery levels in the third quarter have increased as a result of increased demand.

Sales revenues remained flat at $16.7 million, compared to prior-year.

Gross Profit:

Gross profit increased by $29.4 million, or 13.9%, to $240.8 million for the nine months ended September 30, 2021 compared to $211.4 million compared to the nine months ended September 30, 2020.

Adjusted EBITDA increased $23.7 million, or 18.1%, to $155.0 million for the nine months ended September 30, 2021 from $131.2 million for the nine months ended September 30, 2020 and the margin contracted to 43.4% from 43.6%.

The increase in Adjusted EBITDA was driven primarily by increased leasing gross profit as described above, partially offset by increased SG&A.

Excluding acquisition costs and stock-based compensation, SG&A increased $9.5 million in this segment.

The increase was comprised of increased costs for personnel, including commissions and other variable compensation, insurance, computer costs, and bad debt expenses.

Capital Expenditures for Rental Equipment:

Purchases of rental equipment and refurbishments of $24.2 million for the nine months ended September 30, 2021 were $4.5 million lower than for the nine months ended September 30, 2020.

We continue to review available acquisition opportunities with the awareness that any such acquisition may require us to incur additional debt to finance the acquisition and/or to issue shares of our Common Stock or other equity securities as acquisition consideration or as part of an overall financing plan.

In addition, we will continue to evaluate alternatives to optimize our capital structure, which could include the issuance or repurchase of additional unsecured and secured debt, equity securities and/or equity-linked securities.

There can be no assurance as to the timing of any such issuance or repurchase.

On July 1, 2020, in connection with the completion of the Merger, Holdings, WSII, and certain of its subsidiaries, entered into a new asset-based credit agreement, that provides for revolving credit facilities in the aggregate principal amount of up to $2.4 billion, consisting of:

(i) a senior secured asset-based US dollar revolving credit facility in the aggregate principal amount of $2.0 billion (the “US Facility”), available to WSII and certain of its subsidiaries (collectively, the “US Borrowers”), and (ii) a $400.0 million senior secured asset-based multicurrency revolving credit facility (the "Multicurrency Facility") together with the US Facility (collectively, the “2020 ABL Facility”), available to be drawn in US Dollars, Canadian Dollars, British Pounds Sterling or Euros by the US Borrowers, and certain of WSII’s wholly-owned subsidiaries organized in Canada and in the United Kingdom.

COVID-19 Impact on Liquidity

We continue to monitor the impact that the global pandemic is having on our financial operations and liquidity;

however, to date this impact has been immaterial, and we see the adverse impacts of COVID-19 diminishing as the global economy recovers.

We regularly manage all aspects of our business including, but not limited to, monitoring the financial health of our customers, suppliers and other third-party relationships, actively managing our cost structure, reducing or delaying capital spending, and developing new opportunities for growth.

We believe that the actions we have taken in recent years to increase our scale and competitive position and strengthen our balance sheet positioned us well to manage through economic cycles and have positioned us well for the current recovery.

Free Cash Flow for the nine months ended September 30, 2021 was an inflow of $251.7 million as compared to an inflow of $74.8 million for the nine months ended September 30, 2020, an increase in Free Cash Flow of $176.9 million.

Free Cash Flow increased year over year principally as a result of the $217.0 million increase in cash provided by operating activities and partially offset by the $55.9 million increase in cash used in the purchase of rental equipment and refurbishments.

The $130.4 million in cash provided by operating activities for the three months ended September 30, 2021 was returned to shareholders through stock and warrant repurchases and cancellations and reinvested into the business to support the purchase of rental equipment, including VAPS, and refurbishments.

Free Cash Flow for the three months ended March 31, 2022 was an inflow of $54.6 million as compared to an inflow of $91.2 million for the three months ended March 31, 2021, a decrease in Free Cash Flow of $36.6 million.

Free Cash Flow decreased year over year principally as a result of a $42.7 million increase in cash used in the purchase of rental equipment and refurbishments, a $13.4 million decrease in the proceeds from the sale of property, plant and equipment and a $0.6 million decrease in the proceeds from the sale of rental equipment.

These were partially offset by a $23.4 million increase in cash provided by operating activities driven by increased profitability in the business.

The $145.5 million in cash provided by operating activities for the three months ended March 31, 2022 was returned to shareholders through stock and warrant repurchases and cancellations and reinvested into the business to support the purchase of rental equipment, including VAPS, and refurbishments, as well as inorganic growth through mergers and acquisitions.

Material cash requirements

The Company’s material cash requirements include the following contractual and other obligations:

The Company has outstanding debt related to its ABL Facility, 2025 Secured Notes, 2028 Secured Notes, and finance leases, totaling $2.9 billion as of March 31, 2022, $19.8 million of which is obligated to be repaid within the next twelve months.

Refer to Note 9 for further information regarding outstanding debt.

Operating leases

The Company has commitments for future minimum rental payments relating to operating leases, which are primarily for equipment and office space.

As of March 31, 2022, the Company had lease obligations of $282.2 million, with $62.0 million payable within the next twelve months.

In addition to the aforementioned cash requirements, the Company has a Share Repurchase Program authorized by the Board of Directors which allows the Company to repurchase up to $1.0 billion of outstanding shares of Common Stock and equivalents.

This program does not obligate the Company to repurchase any specific amount of shares.

The company believes its cash, cash flows generated from ongoing operations, continued access to its revolving credit facility, as well as access to debt markets, are sufficient to satisfy its currently anticipated cash requirements for the foreseeable future.
