Our Company

Headquartered in Baltimore, Maryland, we are a market leader in the North American specialty rental services industry. We provide innovative modular space and portable storage solutions to diverse end markets utilizing a branch network of over 100 locations throughout the United States, Canada, and Mexico.

We lease modular space and portable storage units to customers in the commercial and industrial, construction, education, energy and natural resources, government, and other end-markets. We deliver "Ready to Work" solutions through our growing offering of value-added products and services ("VAPS"), such as the rental of steps, ramps, and furniture packages, damage waivers, and other amenities. These turnkey solutions offer customers flexible, low-cost and timely solutions to meet their space needs on an outsourced basis. We complement our core leasing business by selling both new and used units, allowing us to leverage our scale, achieve purchasing benefits and redeploy capital employed in our lease fleet. We also provide delivery, installation, and other ancillary products and services.

Since our business combination in November 2017, we have acquired and successfully integrated two businesses—Acton Mobile Holdings, LLC, a Delaware limited liability company ("Acton"), and Onsite Space LLC, an Indiana limited liability company (dba Tyson Onsite) ("Tyson") . These acquisitions were highly complementary to our market strategy, strengthened our position in key markets, and expanded our modular space and portable storage fleet by more than 22,000 units. The acquisitions also expanded the breadth and depth of our "Ready to Work" solutions to existing and incremental customers and markets.

For the year ended December 31, 2017, we generated consolidated revenues of $445.9 million, net loss of $149.8 million and Adjusted EBITDA of $108.8 million. For the year ended December 31, 2017, our Modular—US Segment generated revenues of $392.9 million, loss from continuing operations before income taxes of $12.3 million and Adjusted EBITDA of $110.8 million and our Modular—Other North America Segment generated revenues of $53.7 million, loss from continuing operations before income taxes of $64.6 million and Adjusted EBITDA of $13.1 million. Corporate & other revenues for the year ended December 31, 2017, were ($0.6) million related to intercompany eliminations with our former Remote Accommodations segment, and Adjusted EBITDA was ($15.1) million related to selling, general and administrative costs incurred prior to or as part of the business combination in November 2017 related to the Algeco Group's (as defined below) corporate costs which are not anticipated to be part of the ongoing costs of WSC. Adjusted EBITDA is not a financial measure calculated in accordance with GAAP. For a reconciliation to the most comparable GAAP measure please see "Summary—Summary Consolidated Historical and Pro Forma Financial Data of WillScot—Non-GAAP Financial Measures and Reconciliations."

ModSpace Acquisition

On June 21, 2018, we and our newly-formed acquisition subsidiary, Mason Merger Sub, Inc., a Delaware corporation ("Merger Sub"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with Modular Space Holdings, Inc., a Delaware corporation ("ModSpace" or "MS"), and NANOMA LLC, a New York limited liability company, solely in its capacity as Holder Representative (as defined therein), pursuant to which Merger Sub will merge with and into ModSpace (the "Merger") with ModSpace as the surviving entity in the Merger and continuing as our indirect subsidiary (the "ModSpace Acquisition"). See "Summary—The Transactions." We refer herein to the ModSpace Acquisition and the related transactions, including this offering, the borrowings under the Amended ABL Facility (as defined below), the issuance and sale of the Secured Notes (as defined below), the issuance and sale of the Unsecured Notes (as defined below), and the payment of any related fees and expenses, collectively as the "Transactions."

ModSpace, based in Berwyn, Pennsylvania, is the largest privately held provider of office trailers, portable storage units and modular buildings for temporary or permanent space needs in North America. Building on nearly 50 years of experience, ModSpace serves a diverse set of customers and markets—including commercial, construction, education, government, healthcare, industrial, energy, disaster relief, franchise, and special events—through an extensive branch network that includes 80 operating locations across the United States and Canada.

The ModSpace Acquisition is consistent with our strategic priorities of driving growth and achieving measurable stockholder value creation both organically and through acquisitions. We believe that the ModSpace Acquisition will provide several significant strategic, operational and financial benefits to our company, including:

Enhances our scale improving access and service levels for the combined customer base. The ModSpace Acquisition significantly enhances our scale and market leading positions in key markets. Following the ModSpace Acquisition, we will have a rental fleet with over 81 million square feet of relocatable space, composed of more than 160,000 modular space and portable storage units. The following table illustrates the breakdown of the net book value of combined company rental equipment between the various modular space product types, portable storage, and VAPS as of March 31, 2018.

The original equipment cost of the ModSpace fleet, excluding VAPS, at March 31, 2018 was $1.3 billion.

We believe that our enhanced scale and balanced asset portfolio increase the stability of our cash flows and provide significant operational advantages both to our company and our customers, including the ability to optimize fleet utilization and offer greater fleet inventory across our locations, the ability to offer VAPS through our supply chain, purchasing efficiencies, and the ability to service large customers with national or multi-region footprints.

Accelerates organic growth through the continued penetration of VAPS across all of our modular assets. We have driven sustained growth of VAPS over the last five years with cumulative average annual growth rates of 23% on our modular space units. We believe the ModSpace Acquisition provides the opportunity to expand the reoccurring revenue from value-added products on new contracts relative to the averages across the acquired portfolio. ModSpace's modular space units had average monthly VAPS rates of approximately $86 as of March 31, 2018. This compares to average monthly VAPS rates on delivered units in our Modular—US segment over the twelve months ended March 31, 2018 of $226 per modular space unit. We believe that further upside exists with any further improvements in our delivered rates related to VAPS pricing, penetration, or expansion of our VAPS offering.

Substantial cost savings opportunities. The ModSpace Acquisition presents approximately $60.0 million in estimated annual cost savings through headcount reductions in duplicative corporate and branch functions, consolidation of real estate, and reduction of other selling, general and administrative ("SG&A") expenses including IT, marketing, travel, and professional fees. The following chart provides a breakdown of the approximately $60.0 million in estimated annual cost savings.

Cost Savings Opportunities

We expect that the majority of our estimated annual cost savings will have been executed and in our earnings run-rate by the end of 2019. We expect to incur one-time costs of $42.0 million related to the integration of ModSpace, which we expect will be partly offset by $30.0 million in expected proceeds from the sale of surplus real estate. Additionally, we intend to leverage best practices from both companies to derive incremental cost and cash flow synergies through a consolidated footprint, branch scale efficiency, logistics optimization, sourcing and procurement, repair and maintenance strategy and further fleet optimization.

Extensive branch network with significant overlap. Our combined extensive footprint provides for cost-effective coverage of smaller customers at the local level, while also addressing the needs of larger national and regional customers. Since geographic proximity to customers can be a competitive advantage in the modular space and portable storage industry, we believe that our extensive branch network will allow us to better serve our existing customers and attract new customers. The significant overlap between our and ModSpace's branch networks provides branch rationalization opportunities. We have identified 65 overlapping locations for rationalization which we expect will drive substantial cost savings.

Substantial free cash flow generation. Our recurring revenue, combined with our flexible capital expenditure requirements and working capital profile, has allowed us to generate substantial free cash flows, even through periods of economic downturn. The long-term nature of our leases, with average lease durations in excess of 30 months, produces significant operating income and predictable cash flow. Following the global financial crisis, our average monthly rates increased steadily due to the stability of contracts put in place before the downturn, exposures to other end markets outside of the construction sector, and the introduction of VAPS. These attributes resulted in our Modular Leasing Revenue remaining quite resilient despite declines in overall market volumes and units on rent during the period. We also exercise significant control and discretion over capital expenditures, due to the longevity and relative simplicity of our products, the ability to invest only where needed and when needed to meet demand, and our ability to sell excess fleet during lower utilization periods. Following the completion of the Transactions, we expect to have a strong financial profile with a solid balance sheet, enhanced cash flow and significant growth prospects. We believe we will realize substantial cost and revenue synergies and realize other synergies related to working capital, capital expenditures, and tax obligations by combining the two portfolios of assets. We estimate, subject to utilization limits, the net present value of tax benefits to be acquired by us in the ModSpace Acquisition to be approximately $50.0 million.

Our Strategies Post-ModSpace Acquisition

Key elements of our strategy to accomplish our continued revenue growth and profitability objectives following the ModSpace Acquisition include:

Expanding our "Ready to Work" value proposition. We combine product quality and availability, the largest service network in North America, an industry leading offering of VAPS, and a commitment to customer service to provide increased value to our customers. This attracts new customers, increases customer retention, and increases our margins and return on invested capital. We intend to grow the combined business by continuing to improve the quality, delivery and service of our products and by continuing to introduce new and innovative products and services that complement our core offering to the most attractive industry and geographic end markets. We believe that we can increase our revenues and improve margins as our, ModSpace's and Acton's units on rent at older rates turn over and are replaced with our current VAPS offerings and delivered rates.

Increasing the utilization and yield of our rental fleet. Our leasing and services business accounted for over 90% of our adjusted gross profit for the twelve months ended March 31, 2018 and represents

the core of our business, providing high margin and recurring revenue. We are continually working to increase the utilization and yield of our lease fleet by improving the efficiency and performance of our sales force, expanding penetration of VAPS and enhancing our management information systems. Effective use of real-time information systems allows us to monitor and optimize the utilization of our fleet, allocate our fleet to the highest demand markets, optimize pricing, and determine the best allocation of our capital to invest in fleet and branches as well as to identify opportunities where underutilized lease fleet can be sold to generate cash.

Industry Overview

Our business primarily operates within the modular space and portable storage markets, however, our services span across a variety of related sectors, including furniture rental, transportation and logistics, facilities rental services, and commercial real estate.

Modular Space Market

The modular space market is highly fragmented. Modular space units are non-residential structures designed to meet federal, provincial, state and local building codes, and, in most cases, are designed to be relocatable. Modular space units are constructed offsite, utilizing manufacturing techniques to prefabricate single or multi-story whole building solutions in deliverable modular sections. Units are typically constructed of steel, wood, and conventional building materials.

The modular space market has evolved in recent years as businesses and other potential customers increasingly recognize the value of modular space. The key growth drivers in this market are:

•

Growing need and demand for space—driven by general economic activity, including gross domestic product growth, industrial production, mining and natural resources activity, non-residential construction, urbanization, public and education spending, and the scale and frequency of special events.

•

Increasing shift from traditional fixed, on-site built space to modular space solutions—driven by several advantages as compared with fixed, on-site built space, including:

•: Quick to install—the pre-fabrication of modular space units allows them to be put in place rapidly, providing potential long-term solutions to needs that may have materialized quickly.
•: Flexibility—flexible assembly design allows modular space units to be built to suit a customer's needs while offering customers the ability to adjust their space as their needs change.
•: Cost effectiveness—modular space units provide a cost effective solution for temporary and permanent space requirements and allow customers to improve returns on capital in their core business.
•: Quality—the pre-fabrication of modular space units is based on a repeatable process in a controlled environment, resulting in more consistent quality.
•: Mobility—modular space units can easily be disassembled, transported to a new location and re-assembled.
•: Environmentally friendly—relocatable buildings promote the reuse of facilities, on an as-needed basis by the occupants.

Portable Storage Market

The portable storage market is highly fragmented and remains primarily local in nature. Portable storage provides customers with a flexible and low-cost storage alternative to permanent warehouse

space and fixed-site self-storage. In addition, portable storage addresses the need for security while providing for convenience and immediate accessibility to customers.

Products and Services Post-ModSpace Acquisition

Our modular space and portable storage units are used to meet a broad range of customer needs. Our units are made of wood, steel, or aluminium frames mounted on a steel chassis, and typically range in size from 8 to 14 feet in width and 16 to 70 feet in length. Most units are equipped with air conditioning and heating, electrical and Ethernet cable outlets and, if necessary, plumbing facilities. Our units are transported by truck, either towed (if fitted with axles and hitches) or mounted on flat-bed trailers. Additionally, we offer VAPS along with our lease fleet (collectively, "rental equipment") in order to deliver "Ready to Work" solutions to our customers. Our specific product offerings include:

Modular Space Products

Single-Wide Modular Space Units. Single-wide modular space units include mobile offices and sales offices. These units offer maximum ease of installation and removal and are deployed across the broadest range of applications in our fleet. These units typically have "open interiors" which can be modified using movable partitions and include tile floors, air conditioning and heating units, partitions and, if requested, toilet facilities.

Section Modulars. Section modulars are two or more units combined into one structure. Redi-Plex and ModSpace E-Plex complexes offer advanced versatility for large, open floor plans or custom layouts with private offices. Redi-Plex and ModSpace E-Plex complexes are built with clearspan construction, which eliminates interference from support columns and allows for up to sixty feet of open building width and building lengths that increase in twelve foot increments, based on the number of units coupled together. Our proprietary design meets a wide range of national and state building, electrical, mechanical and plumbing codes, which creates versatility in fleet management. Examples of section modular units include hospital diagnostic annexes, special events headquarters, golf pro shops and larger general commercial offices.

Classrooms. Classroom units are generally double-wide units adapted specifically for use by school systems or universities. Classroom units usually feature teaching aids, air conditioning/heating units, windows and, if requested, toilet facilities.

Panelized and Stackable Offices. AS Flex^TM and ModSpace HQ^TM panelized and stackable offices are the next generation of modular space technology and offer maximum flexibility and design configurations. These units provide a modern, innovative design, smaller footprint, ground level access and interchangeable panels, including all glass panels, that allow customers to configure the space to their precise requirements. These units have the ability to expand upwards (up to three stories) and outwards.

Container Offices. Container offices are International Organization for Standardization ("ISO") certified shipping containers that we convert for office use. They provide safe, secure, ground-level access with fully welded weather-resistant steel corrugated exteriors and exterior window guards made of welded steel and tamper-proof screws. Container offices are available in 20 and 40 foot lengths and in a combination of office and storage floor plans, or all-office floor plans.

Other Modular Space. We offer a range of other specialty products that vary across regions and provide flexibility to serve demands for local markets. Examples include workforce accommodation units used to house workers with dining facilities often in remote locations, blast-resistant units and toilet facilities to complement office and classroom units.

Portable Storage Products

Portable Storage. Storage units are typically ISO shipping containers with swing doors that are repurposed for commercial storage applications. These units are primarily ground-level entry, windowless storage containers made of heavy exterior metals for secure storage and water tightness.

VAPS

We offer a thoughtfully curated portfolio of VAPS that make modular space and portable storage units more productive, comfortable, secure and "Ready to Work" for our customers. We lease furniture, steps, ramps, basic appliances, internet connectivity devices, and other items to our customers for use in connection with our products. We also offer our lease customers a damage waiver program that protects them in case the leased unit is damaged. For customers who do not select the damage waiver program, we bill them for the cost of repairs above and beyond normal wear and tear.

Delivery, Installation and Removal

We provide delivery, site-work, installation, disassembly, unhooking and removal, and other services to our customers for an additional fee as part of our leasing and sales operations. Typically, units are placed on temporary foundations constructed by our in-house service technicians or subcontractors. These in-house service technicians or subcontractors also generally install any ancillary products and VAPS.

Product Leases

Rental equipment leasing is our core business. The vast majority of new lease orders are on standard lease agreements, pre-negotiated master lease or national account agreements. The initial lease periods vary, and our leases are customarily renewable on a month-to-month basis after their initial term. While the initial lease term is often relatively short, the average actual lease duration of our lease portfolio (including month-to-month renewals) is significantly longer. Currently, our average minimum lease terms at delivery for modular space units and portable storage units are 11 months and 7 months, respectively, while the average duration of the combined lease portfolio is 30 months, including those leases acquired as part of the ModSpace, Acton, and Tyson acquisitions.

Customers are responsible for the costs of delivery and set-up, dismantling and pick-up, customer-specified modifications, costs to return custom modifications back to standard configuration at end of lease and any loss or damage beyond normal wear and tear. Our leases generally require customers to maintain liability and property insurance covering the units during the lease term, and to indemnify us from losses caused by the negligence of the customer or their employees.

Product Sales

We complement our core leasing business with product sales. Generally, we purchase new units from a broad network of third-party manufacturers for sale, but do have limited internal production capabilities as well. We typically do not purchase new units for resale until we have obtained firm purchase orders (which normally are non-cancellable and include up-front deposits) for such units. Buying units directly for resale adds scale to our purchasing, which is beneficial to overall supplier relationships and purchasing terms. New unit sales are a natural extension of our leasing operations in situations where customers have long-lived or permanent projects, making it more cost-effective to purchase rather than to lease a standard unit.

In the normal course of managing our business, we also sell idle used rental units at fair market value and units that are already on rent if the customer expresses interest in owning, rather than continuing to rent the unit. The sale of units from our rental equipment has historically been both

profitable and a cost-effective method to finance the replenishment and upgrade of the lease fleet, as well as generate free cash flow during periods of lower rental demand and utilization. Our sales business may include modifying or customizing units to meet customer requirements. We also offer delivery, installation and removal-related services for an additional fee as part of our sales operations.

Post-ModSpace Acquisition End Markets

The following chart provides a breakdown of the pro forma revenue by our key customer end markets:

Pro Forma Revenue by End Market(1)

(1): Based on pro forma revenues for the quarter ended March 31, 2018.

Our key customer end markets include:

Commercial and Industrial

Customers in this category span a variety of industries ranging from commercial offices and warehouses; customers in entertainment, recreation, fast food and retail; transportation; recycling; chemicals and other manufacturing and industrial end-markets.

Construction and Infrastructure

We provide office and storage space to a broad array of contractors associated with non-residential buildings and non-building infrastructure. Our client portfolio includes many of the largest general contractors and engineering, procurement and construction companies in North America. Examples include highway, street, bridge and tunnel contractors; water, sewer, communication and power line contractors; and special construction trades, including glass, glazing and demolition. Our construction and infrastructure customer base is characterized by a wide variety of contractors that are associated with original construction as well as capital improvements in the private, institutional and municipal arenas.

Education

Rapid shifts in populations within regions often necessitate quick expansion of education facilities, particularly in elementary, secondary schools and universities and colleges. Regional and local governmental budgetary pressures, classroom size reduction legislation, refurbishment of existing facilities and the expansion of charter schools have made modular classrooms a convenient and cost-effective way to expand capacity in educational settings. In addition, our products are used as classrooms when schools are undergoing large scale modernization, which allows continuous operation of a school while modernization progresses.

Energy and Natural Resources

Our products are leased to companies involved in up- mid- and down-stream oil and gas, electricity generation and transmission, mining exploration and extraction, forestry and other related sectors.

Government

Government customers consist of national, state, provincial, and local public sector organizations. Modular space and portable storage solutions are particularly attractive to focused niches such as disaster relief, prisons and jails, courthouses, military installations, national security buildings and offices during building modernization.

The representations, warranties and covenants contained in the Merger Agreement are made only for the purposes of the Merger Agreement and are made as of specific dates and are solely for the benefit of the parties to the Merger Agreement. As to factual matters concerning ModSpace, you should not rely upon the representations and warranties in the Merger Agreement.

The Other Financing Transactions

In addition to this offering, we intend to obtain or otherwise incur additional financing for the ModSpace Acquisition as follows:

•: Amended ABL Facility. On July 9, 2018, our indirect subsidiary, Williams Scotsman International, Inc., a Delaware corporation ("WSII"), and certain other of our subsidiaries entered into a first amendment (the "Amended ABL Facility") to their ABL Credit Agreement, dated as of November 29, 2017 (the "ABL Facility") among WSII, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as agent and collateral agent. The Amended ABL Facility will not become effective until the closing of the ModSpace Acquisition. Upon its effectiveness, the Amended ABL Facility will amend the ABL Facility to, among other things, (i) permit the ModSpace Acquisition and the related incurrences of indebtedness by WSII and certain other subsidiaries of the Company to finance the ModSpace Acquisition; (ii) permit the increase of the maximum revolving credit facility amount to $1.35 billion with an accordion feature allowing up to $1.8 billion of capacity; and (iii) increase certain thresholds, basket sizes and default and notice triggers to account for the increased size of the business of WSII and its subsidiaries following the ModSpace Acquisition. We expect WSII will make an incremental draw of $505.0 million under the Amended ABL Facility to finance a portion of the Cash Consideration and certain fees and expenses incurred in connection with the ModSpace Acquisition.
•: Secured Notes Offering. Subsequent to this offering, we expect WSII to offer (the "Secured Notes Offering"), by means of a private placement, approximately $300.0 million in aggregate principal amount of senior secured notes (the "Secured Notes"). The Secured Notes Offering is not part of the offering to which this prospectus supplement relates. The Secured Notes will be offered only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act. This prospectus supplement is not an offer to sell or a solicitation of an offer to buy any Secured Notes being offered in the Secured Notes Offering.
•: Unsecured Notes Offering. Subsequent to this offering, we expect WSII to offer (the "Unsecured Financing"), by means of a private placement, approximately $200.0 million in aggregate principal amount of senior unsecured notes (the "Unsecured Notes"), on the terms and subject to the conditions set forth in the Unsecured Debt Commitment Letter (as defined below). The Unsecured Financing is not part of the offering to which this prospectus supplement relates. The Unsecured Notes will only be offered to accredited investors or qualified institutional buyers under U.S. securities laws. This prospectus supplement is not an offer to sell or a solicitation of an offer to buy any Unsecured Notes being offering in the Unsecured Financing.

We refer to the Amended ABL Facility, the Secured Notes Offering and the Unsecured Financing as the "Other Financing Transactions." We refer to this offering and the Other Financing Transactions collectively as the "Financing Transactions."

The completion of this offering is not contingent upon the completion of the Other Financing Transactions or the consummation of the ModSpace Acquisition. Accordingly, even if the ModSpace Acquisition is not consummated, the shares of Common Stock sold in this offering will remain outstanding, and investors will not have any rights to require us to repurchase, redeem or repay any shares of Common Stock sold in this offering. If the ModSpace Acquisition is not consummated, we intend to use the net proceeds of this offering for general corporate purposes.

Pursuant to an amended and restated commitment letter (the "ABL/Bridge Debt Commitment Letter"), dated July 5, 2018, by and among Bank of America, N.A., Deutsche Bank AG New York Branch, Barclays Bank PLC, Morgan Stanley Senior Funding, Inc., Credit Suisse AG and ING

Capital LLC (collectively, with certain of their respective affiliates, the "Lenders") and us, the Lenders committed to provide (i) an incremental ABL loan facility in an aggregate principal amount of up to $750.0 million; (ii) a senior secured bridge loan facility in an aggregate principal amount of up to $280 million (the "Secured Bridge Facility"); and (iii) a senior unsecured bridge loan facility in an aggregate principal amount of up to $320 million (the "Unsecured Bridge Facility"), on the terms and subject to the conditions set forth in the ABL/Bridge Debt Commitment Letter, to fund a portion of the Cash Consideration for the ModSpace Acquisition and to pay related fees and expenses. Although we do not currently expect to make any borrowings under the Unsecured Bridge Facility or the Secured Bridge Facility, there can be no assurance that such borrowings will not be made. In that regard, we may be required to borrow under the Unsecured Bridge Facility and/or the Secured Bridge Facility if we do not generate sufficient net proceeds from this offering to partially finance the ModSpace Acquisition and related fees and expenses. For additional information regarding the ABL/Bridge Debt Commitment Letter, see "The Transactions—ABL/Bridge Debt Commitment Letter."

Pursuant to a commitment letter (the "Unsecured Debt Commitment Letter"), dated July 24, 2018, by and among Albacore Capital LLP, Canyon Value Realization Fund, L.P. (collectively, with certain of their respective affiliated or managed funds or accounts, the "Unsecured Lenders") and us, the Unsecured Lenders committed to purchase the Unsecured Notes in an aggregate principal amount of up to $200.0 million (which amount may be increased in the event we receive less than $100.0 million of gross proceeds from this offering in an amount equal to the difference between $100.0 million and the gross proceeds received by us from this offering), on the terms and subject to the conditions set forth in the Unsecured Debt Commitment Letter, to fund a portion of the Cash Consideration for the ModSpace Acquisition and to pay related fees and expenses. To the extent that the aggregate gross proceeds from (i) this offering and (ii) the Unsecured Financing (to the extent funded into an escrow account for the purpose of funding the Cash Consideration for the Modspace Acquisition) are at least $300 million, then the Unsecured Bridge Facility commitment under the ABL/Bridge Debt Commitment Letter will be cancelled and terminated in full. However, there is no guarantee that we will be able to raise such gross proceeds under this offering or under the Unsecured Financing in the amounts contemplated or at all. If we do not receive aggregate gross proceeds of at least $300 million from this offering and the Unsecured Financing we intend to borrow under the Unsecured Bridge Facility and/or issue unsecured notes to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act in order to finance the remaining Cash Consideration for the Modspace Acquisition. For additional information regarding Unsecured Debt Commitment Letter, see "The Transactions—Unsecured Debt Commitment Letter."

We cannot assure you that we will complete the ModSpace Acquisition or any of the Other Financing Transactions on the terms contemplated in this prospectus supplement or at all, that the actual amounts will not differ materially from our current plans, or that we will not also, or in lieu thereof, pursue other financings or offer other financial instruments. See "Risk Factors—Risks Related to the ModSpace Acquisition."

For additional information regarding the ModSpace Acquisition and the Other Financing Transactions, see "The Transactions."

Recent Developments

Preliminary Estimated Unaudited Quarterly Results of Operations

We are in the process of finalizing our financial results for the three months ended June 30, 2018. Based on available information to date, we expect our total revenues for the three months ended June 30, 2018 to be in the range of $139.5 to $140.5 million, with the midpoint of this range representing an increase of approximately 27% as compared to the same period in 2017, driven by an increase of approximately 37% in our core leasing and services revenues from both organic growth, and due to the impact of the Acton and Tyson acquisitions. The increase in our core leasing and services business was partially offset by decreases of approximately 44% and 49% in our new and rental unit sales.

We expect our Modular—US segment revenues for the three months ended June 30, 2018 to increase by approximately $26.0 million, or approximately 26%, as compared to the same period in 2017, driven by:

•: Average modular space monthly rental rate growth of approximately 2.5% due to increases both in the price of our units, as well as increased VAPS pricing and penetration. This increase was offset by lower rates on acquired units from Acton and Tyson; and
•: Increased average modular space units on rent of approximately 13,000 units, or approximately 36%, primarily due to the Acton and Tyson acquisitions.

We expect our Modular—Other North America segment revenues for the three months ended June 30, 2018 to increase by approximately $3.0 million, or approximately 25%, as compared to the same period in 2017, driven by:

•: Average modular space monthly rental rate growth of approximately 7% due to increased VAPS pricing and penetration, as well as modest increases in the price of our units; and
•: Increased average modular space units on rent of approximately 500 units, or approximately 10%.

On a pro forma basis, including the results of Acton and Tyson for all periods presented, we expect our core leasing and services revenues for the three months ended June 30, 2018 to increase by approximately $12.5 million, or approximately 10.5%, as compared to our pro forma leasing and services revenues of $119.9 million for the same period in 2017. We expect unit sales for the three months ended June 30, 2018 to decline by approximately $10.0 million, or approximately 57%, as compared to our pro forma unit sales of $17.7 million for the same period in 2017 as a result of lower volumes of sales opportunities and increased focus on our higher margin modular leasing business. We expect our pro forma total revenues for the three months ended June 30, 2018 to increase by approximately $2.5 million, or approximately 2%, as compared to our pro forma total revenues of $137.5 for the same period in 2017

We expect our pro forma Modular—US segment leasing and services revenues for the three months ended June 30, 2018, to increase by approximately $8 million, or approximately 7%, as compared to the same period in 2017, driven by:

•: Average modular space monthly rental rate growth of approximately 9% due to increases both in the price of our units, as well as increased VAPS pricing and penetration; and
•: An increase in average modular space units on rent of approximately 1%.

There are no pro forma adjustments for our Modular—Other North America Segment relating to the Acton or Tyson acquisitions.

We expect our Adjusted EBITDA for the three months ended June 30, 2018 to be in the range of $41.0 million to $42.5 million, with the midpoint of this range representing an increase of $12.9 million, or approximately 45%, over the same period in 2017 for the Modular—US Segment and the Modular—Other North America Segment. This increase was driven by increased gross profit as a result of increased core leasing and services revenues over the same period in 2017, offset by increases in selling, general, and administrative costs related primarily to Acton, prior to expected significant synergy realization, and increased public company costs not incurred in 2017. On a consolidated basis, including the corporate & other segment, the midpoint of the range for our expected Adjusted EBITDA for the three months ended June 30, 2018 of $41.0 million to $42.5 million represents an increase of $15.5 million or approximately 59% over the same period in 2017. Corporate & other included selling, general and administrative costs incurred prior to or as part of the business combination in November 2017 related to the Algeco Group's corporate costs which are not anticipated to be part of the ongoing costs of WSC.

We expect our net (loss) income for the three months ended June 30, 2018 to be in the range of ($1.0) million to $2.0 million, with the midpoint of this range representing an increase of approximately $6.0 million over the same period in 2017. This increase was driven by increased gross profit as a result of increased core leasing and services revenues over the same period in 2017, and approximately $14.0 million of decreased net interest expense as a result of our recapitalization in November 2017. These increases in net (loss) income were partially offset by increases in selling, general, and administrative costs of approximately $16.0 million and an increase in currency losses (gains), net of approximately $7.0 million. The increase in selling, general, and administrative costs were related to the acquisition of Acton (branch network, corporate costs, and headcounts, prior to expected significant synergy realization), costs incurred during the quarter in relation to the Acton integration, increased public company costs not incurred in 2017, and transaction costs associated with this offering, the Other Financing Transactions and the ModSpace Acquisition.

Adjusted EBITDA is a non-GAAP measure. See "Summary—Summary Historical and Pro Forma Consolidated Financial Data of WillScot—Non-GAAP Financial Measures and Reconciliations" in this prospectus supplement for the definitions of such non-GAAP financial measures and below for a reconciliation of our estimated second quarter net (loss) income to estimated second quarter Adjusted EBITDA. Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation from, or as substitutes for analysis of, results as reported under GAAP.

The following table provides an unaudited reconciliation of our estimated second quarter net (loss) income to our estimated second quarter Adjusted EBITDA:

	Three Months Ended June 30, 2018

Other expense(a)		0.0 - 0.5		0.2

Adjusted EBITDA	$	41.0 - 42.5	$	41.8

(a): Other expense represents primarily acquisition-related costs such as advisory, legal, valuation and other professional fees in connection with actual or potential business combinations, which are expensed as incurred, but do not reflect ongoing costs of the business.

We believe that the preliminary estimates set forth above have been prepared on a reasonable basis and reflect our best estimates and judgements based on currently available information. We have provided approximate amounts or ranges rather than specific amounts for the financial results for the three months ended June 30, 2018 because our financial closing procedures for this period are not yet complete. Estimates of results are inherently uncertain and subject to change, and we undertake no obligation to update this information. Our estimates contained in this prospectus supplement may differ materially from our actual results. Our actual results remain subject to the completion of a final review by our management and our board of directors. During the course of the preparation of our quarterly financial statements and related notes for the period ended June 30, 2018, additional items that would require material adjustments to the preliminary estimates presented above may be identified. The preliminary estimates included in this prospectus supplement has been prepared by, and are the responsibility of, management. Our auditors have not audited, reviewed, compiled, or applied agreed upon procedures with respect to the preliminary estimated financial data above and, accordingly, do not express an opinion or any other form of assurance with respect thereto. Our auditors' reports incorporated by reference into this prospectus supplement refer exclusively to our historical financial information. In light of the foregoing, prospective investors are cautioned not to place undue reliance on these estimates. The estimates set forth above were prepared by our management and are based upon a number of assumptions. See "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors."

(a): The Company presents Adjusted EBITDA and Adjusted Gross Profit, which are not financial measures calculated in accordance with GAAP, because they are key metrics used by management to assess financial performance. Our business is capital-intensive and these additional metrics allow management to further evaluate its operating performance. See below for a reconciliation of these non-GAAP financial measures to the most comparable GAAP measures.
(b): Included in corporate & other are selling, general and administrative expenses related to corporate costs of a parent company of WSII's former owners, Algeco Scotsman Global S.ár.l. (together with its subsidiaries, the "Algeco Group") incurred prior to or as part of our business combination with WSII which are not anticipated to be part of our ongoing costs.
(c): A reduction or increase in incremental borrowings under the Amended ABL Facility of $1,000 would cause our interest expense presented in the unaudited pro forma condensed combined statement of operations for year ended December 31, 2017 and the three months ended March 31, 2018 to decrease or increase by approximately $46 and $12, respectively. A 1/8% change in the interest rate to the drawn portion of the ABL facility which is subject to a variable interest rate would increase or decrease the pro forma interest on the $860,200 of outstanding borrowings by approximately $1,075 annually and $269 quarterly. A 1/8% change in the interest rate on the Senior Secured and Unsecured Note which is subject to a fixed interest rate would increase or decrease the pro forma cash interest by $375 and $250 annually and $94 and $63 quarterly, respectively.
(d): An increase or decrease in the size of this offering of $1,000 would cause our financing fees to increase or decrease by approximately $48.

Non-GAAP Financial Measures and Reconciliations

Adjusted EBITDA

We define EBITDA as net income (loss) plus interest (income) expense, income tax expense (benefit), depreciation and amortization. Our 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 equipment and property, plant and equipment;
•: Restructuring costs associated with restructuring plans designed to streamline operations and reduce costs;
•: Costs to integrate acquired companies;
•: Non-cash charges for stock compensation plans; and
•: Other expenses, 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 our results as reported under 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 a measure of cash that will be available to meet

our obligations. The following table provides an unaudited reconciliation of Net loss to Adjusted EBITDA:

The following tables presents a reconciliation of pro forma net (loss) income by company, including acquisition and financing adjustments to pro forma Adjusted EBITDA and pro forma Adjusted Bank EBITDA:

Adjusted Bank EBITDA

We define Adjusted Bank EBITDA as set forth in "Non-GAAP Financial Measures and Reconciliations—Adjusted EBITDA." Our Adjusted Bank EBITDA is calculated in accordance with our ABL Facility and reflects the following further adjustments to Adjusted EBITDA to include pre-acquisition Adjusted EBITDA for Acton and Tyson, and to exclude certain costs excluded from our ABL Facility, plus projected net cost savings, including synergies, to result from actions taken or expected to be taken from implementation of cost savings initiatives, business optimization and other restructuring and integration charges:

•: Any expenses or charges (other than depreciation or amortization expenses) related to any equity offering (including by any Parent Entity) as defined in our ABL Facility, permitted investment, acquisition, disposition, recapitalization or the incurrence of Indebtedness as defined in our ABL Facility permitted to be incurred (including refinancing) (whether or not successful), and any amendment or modification to the terms of any such transaction, including such fees, expenses or charges related to (i) the transactions or (ii) any amendment or other modification of our credit agreement
•: The amount of net cost savings, operating expense reductions, charges attributable to the undertaking and/or implementation of cost savings initiatives and improvements, business

optimization and other restructuring and integration charges, and other synergies projected by the company in good faith to result from actions taken or expected to be taken within eighteen (18) months following the date of determination as a result of specified actions initiated or expected to be taken (calculated on a pro forma basis as though such net cost savings, operating expense reductions, charges and other synergies had been realized on the first day of such period), net of the amount of actual benefits realized during such period from such actions; and

•: Costs associated with, or in anticipation of, or preparation for, compliance with the requirements of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith or other enhanced accounting functions and public company costs

The ABL Facility contains debt incurrence ratios and financial covenant ratios that are calculated by reference to Adjusted Bank EBITDA. Non-compliance with such debt incurrence ratios and financial covenant ratios would prohibit us from being able to incur additional indebtedness other than pursuant to specified exemptions or could result in an event of default under the ABL Facility.

Bank 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 our results as reported under GAAP. Some of these limitations are:

•: Adjusted Bank EBITDA does not reflect changes in, or cash requirements, for our working capital needs;
•: Adjusted Bank EBITDA does not reflect our interest expense, or the cash requirements necessary to service interest or principal payments, on our indebtedness;
•: Adjusted Bank EBITDA does not reflect our tax expense or the cash requirements to pay our taxes;
•: Adjusted Bank EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments;
•: Adjusted Bank 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 Bank EBITDA does not reflect any cash requirements for such replacements;
•: Adjusted Bank EBITDA includes the cost-savings initiatives and synergy estimates that have not been realized. We may not realize the cost synergies that are anticipated from the planned ModSpace Acquisition. See "Risk Factors—We may not realize the cost synergies that are anticipated from the planned ModSpace Acquisition" and "We may fail to realize the anticipated benefits of the ModSpace Acquisition or those benefits may take longer to realize than expected;" and
•: other companies in our industry may calculate Adjusted Bank EBITDA differently, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted Bank EBITDA should not be considered as discretionary cash available to reinvest in the growth of our business or a measure of cash that will be available to

meet our obligations. The following table provides an unaudited reconciliation of Net loss to Adjusted EBITDA, and further reconciliation to Adjusted Bank EBITDA:

Adjusted Gross Profit

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

We have derived the summary consolidated financial data as of September 30, 2017 and 2016 and for the period from March 3, 2017 through September 30, 2017 and from October 1, 2016 through March 2, 2017 and the years ended September 30, 2016 and 2015 from ModSpace's audited consolidated financial statements and the accompanying notes included in our Current Report on Form 8-K filed with the SEC on July 24, 2018. We have derived the summary condensed consolidated financial data as of March 31, 2018 and September 30, 2017 and for the three and six months ended March 31, 2018 and the period from March 3, 2017 through March 31, 2017, the periods from January 1, 2017 through March 2, 2017 and from October 1, 2016 through March 2, 2017 from ModSpace's unaudited consolidated financial statements included in our Current Report on Form 8-K filed with the SEC on July 24, 2018. ModSpace's results for the six months ended March 31, 2018 are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year and we refer you to those consolidated financial statements and accompanying notes in our Current Report on Form 8-K filed with the SEC on July 24, 2018, which are incorporated by reference into this prospectus supplement and the accompanying prospectus.

ModSpace filed a petition on December 21, 2016 with the United States Bankruptcy Court for the District of Delaware for reorganization under the provisions of Chapter 11 of the Bankruptcy Code. ModSpace's Joint Prepackaged Plan of Reorganization (the "Plan") was substantially consummated on March 2, 2017 and the ModSpace emerged from bankruptcy. In connection with its emergence from bankruptcy, ModSpace adopted fresh start accounting. As a result of the application of fresh start accounting, as well as the effects of the implementation of the Plan, the consolidated financial statements of ModSpace subsequent to March 2, 2017 are not comparable with the consolidated financial statements on or prior to that date, which were prepared on a historical basis of accounting. References to "Successor" refer to the financial position and results of operations of the reorganized company subsequent to March 2, 2017. References to "Predecessor" refer to the financial position and results of operations of ModSpace prior to and including March 2, 2017.

Non-GAAP Financial Measures and Reconciliations

Adjusted EBITDA

ModSpace defines Adjusted EBITDA as net income (loss) plus interest (income) expense, income tax expense (benefit), depreciation and amortization. ModSpace Adjusted EBITDA is a non-GAAP

measure based on the definition under ModSpace's credit agreement and reflects the following further adjustments to EBITDA to exclude certain non-cash items and the effect of what they consider transactions or events not related to core business operations:

•: 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 associated with restructuring plans designed to streamline operations and reduce costs;
•: Costs associated with reorganizations and associated accounting adjustments such as fresh start accounting adjustments;
•: Non-cash charges for stock compensation plans; and
•: 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 does not reflect changes in, or cash requirements, for working capital needs;
•: Adjusted EBITDA does not reflect interest expense, or the cash requirements necessary to service interest or principal payments, on indebtedness;
•: Adjusted EBITDA does not reflect tax expense or the cash requirements to pay 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 considered not to be indicative of 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 the 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 the business or as measures of cash that will be available to meet obligations. Please see the unaudited reconciliation of Net loss to Adjusted EBITDA for ModSpace within section "Summary Historical and Pro Forma Consolidated Financial Data of WillScot."

Investing in shares of our Common Stock involves various risks. You should carefully consider the risks and uncertainties described below and the other information in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference, including those risks identified under "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 before deciding whether to purchase shares of our Common Stock.

We intend to use the net proceeds from this offering to fund a portion of the aggregate consideration necessary to complete the ModSpace Acquisition, but this offering is not conditioned upon the closing of the ModSpace Acquisition and we will have broad discretion to determine alternative uses of proceeds.

As described under "Use of Proceeds," we intend to use the net proceeds from this offering, together with the net proceeds of the Other Financing Transactions, to fund the Cash Consideration for the ModSpace Acquisition and to pay related fees and expenses. However, this offering is not conditioned upon the closing of the ModSpace Acquisition. If the ModSpace Acquisition is not consummated, we will have broad discretion in the application of the net proceeds from this offering such as using the proceeds from this offering for general corporate purposes, and holders of our Common Stock will not have the opportunity as part of their investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use.

The ModSpace Acquisition may not be completed within the expected timeframe or at all, and the failure to complete the ModSpace Acquisition may negatively affect the trading price of our Common Stock and could adversely affect our financial results.

The ModSpace Acquisition is subject to risks and uncertainties, including: (i) the risk that the ModSpace Acquisition may not be completed, or completed within the expected timeframe, including as a result of the possibility that a governmental entity may prohibit, delay or refuse an approval required to complete the ModSpace Acquisition; or (ii) costs relating to the ModSpace Acquisition (including in respect of the financing of the ModSpace Acquisition) may be greater than expected. If the ModSpace Acquisition is not completed or if there are significant delays in completing the planned acquisition, it could negatively affect the trading price of our Common Stock, adversely affect our future business and financial results and could result in our failure to realize certain synergies relating to such acquisition. Any failure to consummate the ModSpace Acquisition could also result in a negative reaction from the financial markets, particularly if the current market prices reflect market assumptions that the Merger will be completed, which could cause the value of your investment in our Common Stock to decline. If the ModSpace Acquisition does not close due to the occurrence of certain regulatory events, we may be required to pay a $35 million termination fee to ModSpace.

We may not realize the cost synergies that are anticipated from the planned ModSpace Acquisition.

The benefits that are expected to result from the ModSpace Acquisition, including the anticipated annual cost savings included herein, will depend, in part, on our ability to realize such anticipated cost synergies. Our success in realizing these cost synergies, and the timing of this realization, depends on the successful integration of ModSpace. See "—We may fail to realize the anticipated benefits of the ModSpace Acquisition or those benefits may take longer to realize than expected."

Even if we are able to integrate ModSpace successfully, this integration may not result in the realization of the full benefits of the cost synergies that we currently expect from the ModSpace Acquisition, and we cannot guarantee that these benefits will be achieved within anticipated timeframes

or at all. For example, we may not be able to eliminate duplicative costs. Moreover, we may incur unanticipated expenses in connection with the integration of ModSpace. While it is anticipated that certain expenses will be incurred to achieve cost synergies, such expenses are difficult to estimate accurately, and may exceed current estimates. Accordingly, the benefits from the planned acquisition may be offset by costs incurred to, or delays in, integrating the businesses.

We may fail to realize the anticipated benefits of the ModSpace Acquisition or those benefits may take longer to realize than expected.

Our ability to realize the anticipated benefits of the ModSpace Acquisition, including realizing revenue growth opportunities from employing our operating strategy in the ModSpace business, annual cost savings and certain tax benefits, will depend, to a large extent, on our ability to integrate ModSpace's business with our business, which is a complex, costly and time-consuming process. We will be required to devote significant management attention and resources to integrate the business practices and operations of WillScot and ModSpace. The integration process may disrupt our business and, if implemented ineffectively, could restrict the realization of the full expected benefits. The failure to meet the challenges involved in the integration process and to realize the anticipated benefits of the ModSpace Acquisition could cause an interruption of, or a loss of momentum in, our operations and could adversely affect our business, financial condition and results of operations.

In addition, the integration of ModSpace may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customers and other business relationships, and diversion of management's attention. Additional integration challenges include:

Many of these factors will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenues and diversion of management's time and energy, which could adversely affect our business, financial condition and results of operations and result in us becoming subject to litigation. In addition, even if ModSpace is integrated successfully, the anticipated benefits of the ModSpace Acquisition may not be realized, including the sales or growth opportunities that are anticipated. These benefits may not be achieved within the anticipated time frame, or at all. Further, additional unanticipated costs may be incurred in the integration process. All of these factors

could cause reductions in our earnings per share, decrease or delay the expected accretive effect of the ModSpace Acquisition and negatively impact the price of our Common Stock. As a result, it cannot be assured that the ModSpace Acquisition will result in the realization of the full anticipated benefits.

Investors will not have any rights to require us to repurchase, redeem or repay any shares of Common Stock offered hereby if the ModSpace Acquisition is not completed.

This offering is not contingent on completion of the ModSpace Acquisition. Investors will not have any rights to require us to repurchase, redeem or repay any shares of Common Stock offered hereby if the ModSpace Acquisition is not completed. Accordingly, even if the ModSpace Acquisition is not completed, shares of our Common Stock sold in this offering will remain outstanding. Further, investors will not have any right to require us to repurchase, redeem or repay any shares of the Common Stock offered hereby, if, subsequent to the completion of this offering, we experience any changes in our business or financial condition or if the terms of the ModSpace Acquisition or the financing thereof change.

The ModSpace Acquisition could be subject to review by antitrust authorities in the United States.

We believe that the ModSpace Acquisition is exempt from notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in the United States. However, we cannot provide assurances that the ModSpace Acquisition will not be subject to antitrust review in the United States. To the extent the ModSpace Acquisition is subject to such antitrust review, we can provide no assurances that (i) the review will not delay or render us unable to complete the ModSpace Acquisition or (ii) we would not be subject to asset divestitures or other remedial measures.

The pendency of the ModSpace Acquisition could adversely affect our business, financial results and operations, and the market price of shares of our Common Stock.

The announcement and pendency of the ModSpace Acquisition could cause disruptions and create uncertainty surrounding our business and affect our relationships with our customers and employees. In addition, we have diverted, and will continue to divert, significant management resources to complete the ModSpace Acquisition, which could have a negative impact on our ability to manage existing operations or pursue alternative strategic transactions, which could adversely affect our business, financial condition and results of operations. Until the completion of the ModSpace Acquisition, holders of shares of Common Stock will be exposed to the risks faced by our existing business without any of the potential benefits from the ModSpace Acquisition. As a result of investor perceptions about the terms or benefits of the ModSpace Acquisition, the market price of shares of Common Stock may decline.

If the ModSpace Acquisition is completed, ModSpace may underperform relative to our expectations.

Following completion of the ModSpace Acquisition, we may not be able to maintain the growth rate, levels of revenue, earnings or operating efficiency that we and ModSpace have achieved or might achieve separately. The business and financial performance of ModSpace are subject to certain risks and uncertainties. Our failure to do so could have a material adverse effect on our financial condition and results of operations.

Our actual financial position and results of operations may differ materially from the unaudited pro forma financial information included and incorporated by reference into this prospectus supplement.

The unaudited pro forma financial information included and incorporated by reference into this prospectus supplement is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of operations would have been had the ModSpace

Acquisition, this offering and the Other Financing Transactions been completed on the dates indicated. The unaudited pro forma financial information has been derived from the audited and unaudited historical financial statements of WillScot and ModSpace, and reflects assumptions and adjustments that are based upon preliminary estimates and our successful completion of the ModSpace Acquisition, this offering and the Other Financing Transactions. The assets and liabilities of ModSpace have been preliminarily estimated using assumptions that our management believes are reasonable utilizing information currently available. The process for estimating the fair value of acquired assets and assumed liabilities requires the use of judgment in determining the appropriate assumptions and estimates. These estimates may be revised as additional information becomes available and as additional analyses are performed. Accordingly, the final acquisition accounting adjustments may differ materially from the pro forma adjustments reflected herein. In addition, the assumptions used in preparing the unaudited pro forma financial information, including assumptions as to the successful completion of the ModSpace Acquisition, this offering and the Other Financing Transactions may not prove to be accurate, and other factors may adversely affect our financial condition or results of operations following the closing of the ModSpace Acquisition and negatively impact the price of shares of our Common Stock.

Our credit ratings may be impacted by the additional indebtedness we expect to incur in connection with the ModSpace Acquisition and any negative impact on our credit ratings may impact the cost and availability of future borrowings and, accordingly, our cost of capital.

Our credit ratings at any time will reflect each rating organization's then opinion of our financial strength, operating performance and ability to meet our debt obligations. We anticipate that the additional indebtedness we expect to incur in connection with the ModSpace Acquisition may result in a negative change to our credit ratings, including a potential downgrading. Any reduction in our credit ratings may limit our ability to borrow at interest rates consistent with the interest rates that have been available to us prior to the ModSpace Acquisition and the Other Financing Transactions. If our credit ratings are further downgraded or put on watch for a potential downgrade, we may not be able to sell additional debt securities or borrow money in the amounts, at the times or interest rates or upon the more favorable terms and conditions that might be available if our current credit ratings were maintained.

We expect to incur significant costs and significant indebtedness in connection with the consummation of the Transactions, including the ModSpace Acquisition, and the integration of ModSpace into our business, including legal, accounting, financial advisory and other costs.

We expect to incur significant costs in connection with integrating the operations, products and personnel of ModSpace into our business, in addition to costs related directly to completing the Transactions. These costs may include costs for:

In addition, we expect to incur significant non-recurring costs associated with integrating and combining the operations of ModSpace and its subsidiaries, which cannot be estimated accurately at this time. While we expect to incur a significant amount of transaction fees and other one-time costs related to the consummation of the Transactions, additional unanticipated costs may yet be incurred. Any expected elimination of duplicative costs, as well as the expected realization of other efficiencies related to the integration of our operations with those of ModSpace, that may offset incremental transaction and transaction-related costs over time, may not be achieved in the near term, or at all.

In addition, we expect to incur and/or assume significant new indebtedness in connection with the Transactions. The debt we incur or assume in connection with the Transactions may limit our financial and operating flexibility, and we may incur additional debt, which could increase the risks associated with our substantial indebtedness. Our substantial indebtedness may have material consequences for our business, financial condition and results of operations. See "—Our credit ratings may be impacted by the additional indebtedness we expect to incur in connection with the ModSpace Acquisition and any negative impact on our credit ratings may impact the cost and availability of future borrowings and, accordingly, our cost of capital."

The ModSpace Acquisition will significantly increase our goodwill and other intangible assets.

We have a significant amount, and following the ModSpace Acquisition will have an additional amount, of goodwill and other intangible assets on our consolidated financial statements that are subject to impairment based upon future adverse changes in our business or prospects. The impairment of any goodwill and other intangible assets may have a negative impact on our consolidated results of operations.

Our ability to use ModSpace's net operating loss carryforwards and other tax attributes may be limited.

As of March 31, 2018, we had US net operating loss ("NOL") carryforwards of approximately $269.9 million for US federal income tax and state tax purposes available to offset future taxable income, prior to consideration of annual limitations that may be imposed under Section 382 ("Section 382") of the Internal Revenue Code of 1986, as amended (the "Code"). The US NOL carryforwards begin to expire in 2028 if not utilized. In addition, we had foreign NOLs of $9.9 million as a result of our operations in Mexico. The Mexico NOL carryforwards begin to expire in 2020 if not utilized.

As of September 30, 2017, ModSpace had US NOL carryforwards of approximately $655.0 million, gross, for US federal income tax and state tax purposes available to offset future taxable income, prior to consideration of annual limitations that may be imposed under Section 382. ModSpace's US NOL carryforwards begin to expire in 2022 if not utilized. As of September 30, 2017, ModSpace also recorded a net of tax amount of $104.9 million of a valuation allowance on its US federal and state NOL carryforwards which does not take into account the impacts of Tax Cuts and Jobs Act of 2017, specifically the impacts of the reduced federal rate of 21%.

We may be unable to fully use ModSpace's NOL carryforwards, if at all. Under Section 382 and corresponding provisions of US state law, if a corporation undergoes an "ownership change," generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation's ability to use its pre-change US NOLs and other applicable pre-change tax attributes, such as research and development tax credits, to offset its post-change income may be limited. We have not completed a Section 382 analysis and therefore cannot forecast or otherwise determine our ability to derive any benefit from our various federal or state tax attribute carryforwards at this time. As a result, if we earn net taxable income, our ability to use our pre-change US NOL carryforwards to offset US federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of US NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

Lastly, we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If we determine that an ownership change has occurred and our ability to use our historical NOL and tax credit carryforwards is materially limited, it may result in increased future tax obligations.

The price of our Common Stock may be volatile, which could cause the value of your investment to decline.

The market price of our Common Stock has fluctuated, and may in the future continue to fluctuate, significantly from time to time, and may be influenced by many factors, some of which are beyond our control, including those described in this "Risk Factors" section (including under the heading "—Risks Related to the ModSpace Acquisition" above) and the following:

Broad market fluctuations or any failure of our operating results in a particular quarter to meet market expectations may adversely affect the market price of shares of our Common Stock and the value of your investment. Occasionally, periods of volatility in the market price of a company's securities may lead to the institution of securities class action litigation against a company. If we are subject to such volatility in the price of shares of our Common Stock, we may be the target of such securities litigation in the future. Such legal action could result in substantial costs to defend our interests and a diversion of management's attention and resources, each of which would have a material adverse effect on our business and operating results and the market price of shares of Common Stock may decline.

Sales of a significant number of shares of our Common Stock in the public markets, or the perception of the likelihood of such sales, could depress the market price of shares of our Common Stock.

Sales of a substantial number of shares of our Common Stock in the public markets and the availability of those shares for sale could adversely affect the market price of our Common Stock. Such sales, or the perception in the market that holders of a large number of shares intend to sell shares, could depress the market price of our Common Stock and impair our ability to raise capital through the sale of additional equity securities. Under our existing Amended and Restated Registration Rights Agreement, dated November 29, 2017 (the "Registration Rights Agreement") by and among the Company and the investors party thereto, including an affiliate of TDR Capital, certain of the Founders (as defined below) certain of our directors and certain transferees of the Founders (the "Registration Rights Parties"), the Registration Rights Parties have the right to request an unlimited number of demands, customary shelf registration rights, subject to certain conditions, and piggyback registration rights with respect to registration statements filed by us. In connection with the ModSpace Acquisition, we expect to amend the Registration Rights Agreement to include certain sellers of ModSpace pursuant to which they will join as Registration Rights Parties for the shares of Common Stock received in connection with the ModSpace Acquisition and shares of Common Stock issuable upon exercise of the ModSpace Warrants, subject to certain conditions. See "The Transactions—Second Amended and Restated Registration Rights Agreement." The Registration Rights Parties also may request that we include such Common Stock in certain future registration statements or offerings of Common Stock by us. We cannot predict the effect that future sales of Common Stock or other equity-related securities would have on the market price of our Common Stock.

In addition to the Registration Rights Agreement, Double Eagle Acquisition LLC ("DEAL") and Harry E. Sloan (the "Founders") deposited 12,425,000 shares of our Class A Common Stock in escrow for a period of three years, subject to early release, pursuant to an earnout agreement entered into at the closing of the business combination with WSII (the "Earnout Agreement"). On January 19, 2018, 6,212,500 shares of Common Stock were released from escrow in accordance with the terms of the Earnout Agreement. In addition, the Founders and our former independent directors (the "initial

shareholders") have agreed not to transfer, assign or sell any of their shares of Class A Common Stock until the date that is one year after the date of the consummation of the business combination on November 29, 2017 or earlier if we consummate a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of our stockholders having the right to exchange their shares of Common Stock for cash, securities or other property. However, assuming such shares are released to the Founders in accordance with the Earnout Agreement (including the anticipated release of shares upon completion of the ModSpace Acquisition), following the termination of these transfer restrictions, we cannot predict what effect, if any, market sales of Common Stock held by our initial shareholders or any other shareholder or the availability of these shares for future sale will have on the market price of our Common Stock.

This offering is expected to be dilutive, and there may be future sales or other dilution of our equity, which may adversely affect the market price of the shares of our Common Stock and/or dilute the value of shares of our Common Stock.

Giving effect to the issuance of shares of Common Stock in this offering, the receipt of the expected net proceeds and the use of those proceeds as described under "Use of Proceeds," we expect that this offering will have a dilutive effect on our expected earnings per share for the year ending December 31, 2018. In addition, shares of Common Stock and warrants issued as consideration for the ModSpace Acquisition will have a further dilutive effect. Moreover, to the extent shares are subsequently issued upon the exercise of options or warrants or the vesting of restricted stock units, you will incur further dilution. The actual amount of dilution cannot be determined at this time and will be based upon numerous factors.

If securities or industry analysts cease to publish research, or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our Common Stock will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. In addition, if our operating results fail to meet the forecasts of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

We do not intend to pay dividends on our Common Stock so any returns will be limited to the value of our Common Stock.

We have never declared or paid any cash dividends on our Common Stock. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock

Our principal stockholder controls a majority of our outstanding Common Stock and will continue to following this offering, and it may take actions or have interests that may be adverse to or conflict with those of our other stockholders.

Sapphire Holding S.à r.l. ("Sapphire"), an entity controlled by TDR Capital, beneficially owned approximately 54.8% of our outstanding shares of Common Stock as of July 20, 2018. Upon the completion of this offering, we expect Sapphire will own approximately 50.1% of our outstanding shares of Common Stock. In addition, pursuant to the terms of the Earnout Agreement and the occurrence of a certain triggering event as described therein, Sapphire may receive additional shares of our Common Stock upon release from escrow, as set forth in the Earnout Agreement.

Moreover, Sapphire's ownership of our Common Stock may also adversely affect the trading price for our Common Stock to the extent investors perceive disadvantages in owning shares of a company with a majority stockholder or in the event Sapphire takes any action with its shares that could result in an adverse impact on the price of our Common Stock, including any pledge or other use of its share of our Common Stock in connection with a loan. Sapphire will not be restricted from pledging any or all of its shares of our Common Stock pursuant to the lock-up agreements described herein. See "Underwriting." In the case of any pledge of its shares of our Common Stock in connection with a loan, in the event of a default, lenders could foreclose upon any or all of such pledged shares of our Common Stock. The sale of a significant amount of shares of our Common Stock at any given time or the perception that such sales could occur, including sales of any pledged shares that are foreclosed upon, could adversely affect the prevailing market price of our Common Stock. Moreover, the occurrence of a foreclosure, and a subsequent sale of all, or substantially all, of the pledged shares of our Common Stock in connection with such a loan could result in a change of control under our Supplemental Indenture dated February 15, 2018, by and among WSII, the Guarantors party thereto, and Deutsche Bank Trust Company Americas as trustee and collateral agent, the ABL Facility, the Amended ABL Facility, and future agreements that may we enter into, even when such a change may not be in the best interest of our stockholders. Such a sale of the pledged shares of our Common Stock may also result in another shareholder beneficially owning a significant amount of our common stock and being able to exert a significant degree of influence or actual control over our management and affairs. Such shareholder's interests may be different from or conflict with those of our other shareholders. In addition, TDR Capital is in the business of making investments in companies and may, from time to time, acquire interests in businesses that directly or indirectly compete with our business, as well as businesses that are significant existing or potential customers. TDR Capital may acquire or seek to acquire assets that we seek to acquire and, as a result, those acquisition opportunities may not be available to us or may be more expensive for us to pursue, and as a result, the interests of TDR Capital may not coincide and may even conflict with the interests of our other stockholders.

Pursuant to the terms of the Merger Agreement, by and among us, Merger Sub, ModSpace and, solely in its capacity as the Holder Representative, NANOMA LLC ("Holder Representative"), Merger Sub, our indirect subsidiary, has agreed to merge with and into ModSpace, with ModSpace surviving as our indirect subsidiary.

Under the terms of the Merger Agreement, the consideration to be paid by us for ModSpace consists of: (A) the Cash Consideration; (B) 6,458,500 shares of Common Stock, subject to adjustments as contemplated by the Merger Agreement; and (C) warrants to purchase 10,000,000 shares of Common Stock at an exercise price of $15.50 per share on the terms and subject to the conditions set forth in the ModSpace Warrant Agreement, as described herein. Such consideration shall be distributed on a pro rata basis to the record holders of issued and outstanding common stock of ModSpace and holders of vested restricted stock unit awards (collectively, the "Holders") based on their ownership in ModSpace immediately prior to closing; provided that any Holders who are not accredited investors or qualified institutional buyers under U.S. federal securities laws or hold or would hold less than 1,000 shares of ModSpace common stock as of the closing date of the ModSpace Acquisition shall only receive Cash Consideration adjusted accordingly.

The Cash Consideration will be increased by cash on hand at ModSpace as of the closing and reduced by unpaid expenses of ModSpace relating to the ModSpace Acquisition and prior restructuring of ModSpace and the repayment of ModSpace's existing indebtedness in accordance with the payoff letter to be delivered pursuant to the Merger Agreement, and will also be subject to a net working capital adjustment based on a target net working capital and accounting principles set forth in the Merger Agreement. The Cash Consideration is subject to post-closing adjustment with respect to actual cash, indebtedness, and working capital in accordance with the terms of the Merger Agreement. Prior to any distribution of the adjusted Cash Consideration by the paying agent to the Holders, we will deduct from the Cash Consideration and deliver to the Holder Representative prior to the closing of the ModSpace Acquisition an amount equal to $500,000 to pay fees and expenses of the Holder Representative to the extent payable by the Holders, and an amount equal to $3,000,000 to an escrow account to secure Holders' obligations with respect to an above-referenced post-closing adjustments to the Cash Consideration.

The shares of Common Stock received by the Holders as a portion of the purchase price will be subject to a lock-up agreement prohibiting sales, transfers or other dispositions (other than to certain permitted transferees) for a period of six months following the closing of the ModSpace Acquisition. The holders of the Common Stock would also be afforded certain customary registration rights consistent with the terms of the Registration Rights Agreement, as further described below.

In connection with the transactions contemplated by the Merger Agreement, we have obtained, at our sole cost and expense, a representations and warranties insurance policy, solely for our and our subsidiaries benefit. Except for damages arising from fraud, willful misconduct or intentional misrepresentation, we shall have no recourse against ModSpace or its Holders for breaches under the Merger Agreement or in connection with the ModSpace Acquisition other than pursuant to such representations and warranties policy.

The ModSpace Acquisition and Merger Agreement have been approved by our Board of Directors and the respective boards of directors of Holdings, as sole stockholder of WSII, and WSII, as sole

stockholder of Merger Sub. The ModSpace Acquisition and Merger Agreement have also been approved by the board of directors of ModSpace and Holders of a majority of the issued and outstanding shares of ModSpace. On July 16, 2018, the Canadian Competition Bureau issued a No Action Letter relating to the ModSpace Acquisition.

The Merger Agreement contains certain customary conditions to closing, including relating to certain antitrust approvals. The Merger Agreement further provides that in no event shall we be obligated to take any action with respect to obtaining any clearance under any antitrust law that, individually or in the aggregate, (i) would, individually or in the aggregate, reasonably be expected to result in a reduction of greater than 3.5% of the consolidated EBITDA of the combined business of WillScot and ModSpace after giving effect to the ModSpace Acquisition (as calculated pursuant to terms of the ABL Facility) or (ii) would, or would reasonably be expected to have a material adverse effect on the combined business (a "Regulatory Adverse Effect").

The Merger Agreement may be terminated by us and ModSpace under certain circumstances, including, among others: (i) by mutual consent; (ii) by either ModSpace or us if (A) the ModSpace Acquisition shall not have occurred on or prior to November 18, 2018, which shall be subject to automatic extension to December 18, 2018 if certain conditions to the consummation of the ModSpace Acquisition have been met by such date and subject to further extension by mutual agreement of the parties, or (B) if any governmental entity enforces, enacts or enters any final non-appealable law, judgment, order, decree, injunction, ruling or other action which would make the ModSpace Acquisition illegal or otherwise enjoin or prohibit the consummation of the ModSpace Acquisition; and (iii) by us upon the issuance of a non-appealable order, injunction, decree, ruling, divestiture requirement or other action taken by a governmental entity which would have a Regulatory Adverse Effect. In the event the Merger Agreement is terminated by either ModSpace or us pursuant to (ii)(B) in the event the applicable law, judgment, order, decree, injunction, ruling or other action is taken under antitrust laws, or in the event the Merger Agreement is terminated by us pursuant to (iii) above, we shall pay ModSpace a termination fee equal to $35 million.

Pursuant to the terms of the Merger Agreement, ModSpace has agreed to use commercially reasonable efforts to negotiate in good faith and take all steps reasonably necessary in connection therewith to consider alternative acquisition structures pursuant to which we may acquire ModSpace in order to most effectively maximize tax benefits to the parties.

A copy of the Merger Agreement is included as an exhibit to our Current Report on Form 8-K filed with the SEC on June 22, 2018, which is incorporated by reference into this prospectus supplement. The foregoing description does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement. The Merger Agreement has been incorporated by reference herein solely to provide investors and security holders with information relating to its terms. It is not intended to be a source of financial, business or operational information about ModSpace or its subsidiaries or affiliates. The representations, warranties and covenants contained in the Merger Agreement are made only for the purposes of the Merger Agreement and are made as of specific dates and are solely for the benefit of the parties to the Merger Agreement. As to factual matters concerning ModSpace, you should not rely upon the representations and warranties in the Merger Agreement.

As a condition precedent to the closing of the transactions contemplated by the Merger Agreement, we, Sapphire, the ModSpace Investors (as defined therein), the Initial Investors (as defined

therein), and the Joinder Parties (as defined therein) expect to enter into, subject to the receipt of the requisite approval of existing parties to our Registration Rights Agreement, a second amended and restated registration rights agreement (the "Second Amended and Restated Registration Rights Agreement") that further amends and restates the Registration Rights Agreement and provides such investors with certain demand, shelf and piggyback registration rights covering all shares of Common Stock owned by each investor, and certain warrants and shares of Common Stock issued or issuable upon the exercise of such warrants beneficially owned by such investor until such shares and warrants cease to be "Registrable Securities" as defined in the Registration Rights Agreement. The Second Amended and Restated Registration Rights Agreement provides each investor the right to request an unlimited number of demands at any time following the consummation of the ModSpace Acquisition and customary shelf registration rights, in each case, subject to certain conditions. In addition, the agreement grants the ModSpace Investors and the Initial Investors piggyback registration rights with respect to registration statements filed subsequent to the consummation of the ModSpace Acquisition. We are responsible for all Registration Expenses (as defined in the Registration Rights Agreement) in connection with any demand, shelf or piggyback registration by any of the initiating holders party thereto. The registration rights under the Second Amended and Restated Registration Rights Agreement are subject to customary lock up provisions.

As a condition precedent to the closing of the transactions contemplated by the Merger Agreement, we expect to enter into a warrant agreement (the "ModSpace Warrant Agreement") with the warrant agent named therein that governs the terms of the ModSpace Warrants to be issued to the Holders of ModSpace as partial consideration under the Merger Agreement. The ModSpace Warrant Agreement provides for the issuance of 10,000,000 shares of Common Stock to the Holders at an exercise price of $15.50 per share on a one to one basis, which may be adjusted in the event of an increase in the number of outstanding shares of Common Stock by share dividends (or a share split-up or the payment of extraordinary dividends), a decrease in the number of shares of Common Stock by a consolidation, reverse split or similar transaction and in the in the event of certain reorganization transactions. Under the ModSpace Warrant Agreement, the ModSpace Warrants are not redeemable and may be replaced for replacement securities upon the occurrence of certain reorganization transactions of ours (other than those that would lead to an adjustment in the exercise price of the ModSpace Warrants). The ModSpace Warrants become exercisable on 180th day after the consummation of the Merger and expire on November 29, 2022. Under the Second Amended and Restated Registration Rights Agreement, we will agree to use our commercially reasonable efforts to file and have declared effective a shelf registration statement for the shares of Common Stock issuable upon exercise of the ModSpace Warrants within 180 days after the consummation of the ModSpace Acquisition and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the ModSpace Warrants in accordance with the provisions of the ModSpace Warrant Agreement. The ModSpace Warrant Agreement will contain certain customary Securities Act restrictions on the transfer of the ModSpace Warrants issued thereunder.

Pursuant to the ABL/Bridge Debt Commitment Letter, the Lenders committed to provide (i) an incremental ABL loan facility in an aggregate principal amount of up to $750.0 million; (ii) the Secured Bridge Facility; and (iii) the Unsecured Bridge Facility, on the terms and subject to the conditions set forth in the ABL/Bridge Debt Commitment Letter, to fund a portion of the Cash Consideration for the ModSpace Acquisition and to pay related fees and expenses.

The ABL/Bridge Debt Commitment Letter provides that any net cash proceeds received by us from this offering will, to the extent they are to be used to fund the ModSpace Acquisition, reduce the

commitments of the Lenders as follows: (i) first, the commitments of the Lenders in respect of the Unsecured Bridge Facility will be automatically and immediately reduced and terminated, on a dollar-for-dollar basis, by the first $70.0 million of such proceeds and (ii) second, to the extent those proceeds exceed $70.0 million, amounts to be funded under the ABL Facility will be automatically and immediately reduced, on a dollar-for-dollar basis, by the amount of such excess. Although we do not currently expect to make any borrowings under the Unsecured Bridge Facility or the Secured Bridge Facility, there can be no assurance that such borrowings will not be made. In that regard, we may be required to borrow under the Unsecured Bridge Facility and/or the Secured Bridge Facility if we do not generate sufficient net proceeds from this offering to partially finance the ModSpace Acquisition and related fees and expenses.

Pursuant to the Unsecured Debt Commitment Letter, the purchasers of the Unsecured Notes committed to purchase the Unsecured Notes in an aggregate principal amount of up to $200.0 million (which amount may be increased in the event we receive less than $100.0 million of gross proceeds from this offering in an amount equal to the difference between $100.0 million and the gross proceeds received by us from this offering), on the terms and subject to the conditions set forth in the Unsecured Debt Commitment Letter.

The Unsecured Notes will mature 5 years and 3 months after the date of issuance. The Unsecured Notes will bear interest at a rate of 10.0% per annum if paid in cash (or if paid in kind, 11.5% per annum) for the first 2 years and 6 months after the date of issuance and thereafter increasing to 12.5% per annum with no paid in kind option, in each case payable semi-annually. The Unsecured Notes will be WSII's general unsecured obligations and will rank pari passu in right of payment with all of WSII's existing and future senior indebtedness, effectively junior to all of WSII's existing and future secured indebtedness, including the Amended ABL Facility, WSII's existing 7.875% senior secured notes due 2022 (the "2022 Notes") and the Secured Notes, to the extent of the value of the collateral securing such indebtedness, and senior in right of payment to any of WSII's future unsecured subordinated indebtedness.

The Unsecured Notes will be fully and unconditionally guaranteed, jointly and severally, by Holdings and each of our direct and indirect domestic subsidiaries. Such guarantees will rank pari passu in right of payment with all of the guarantors' existing and future senior indebtedness (except with respect to the guarantee by WillScot Equipment II, a Delaware limited liability company, whose guarantee will be subordinated to its obligations under the Amended ABL Facility), effectively junior to all of their existing and future secured indebtedness, including the Amended ABL Facility, the 2022 Notes and the Secured Notes, to the extent of the value of the collateral securing such indebtedness, and senior in right of payment to any of the guarantors' future unsecured and subordinated indebtedness.

The Unsecured Notes will not be pre-payable until the date that is six months after the date of issuance. Thereafter, the Unsecured Notes will be redeemable or prepayble at (a) par plus a make-whole premium until the date that is one year after the date of issuance, (b) 102% of the principal amount thereof plus accrued and unpaid interest to the date of payment if redeemed or prepaid during the period from 12 months after the date of issuance through 18 months after the date of issuance, (c) 104% of the principal amount thereof plus accrued and unpaid interest to the date of payment if redeemed or prepaid during the period from 18 months after the date of issuance through 30 months after the date of issuance and (d) 106% of the principal amount thereof plus accrued and unpaid interest to the date of payment if redeemed or prepaid thereafter.

To the extent that the aggregate gross proceeds from (i) this offering and (ii) the Unsecured Financing (to the extent funded into an escrow account for the purpose of funding the Cash

Consideration for the Modspace Acquisition) are at least $300 million, then the Unsecured Bridge Facility commitment under the ABL/Bridge Debt Commitment Letter will be cancelled and terminated in full. However, there is no guarantee that we will be able to raise such gross proceeds under this offering or under the Unsecured Financing in the amounts contemplated or at all. If we do not receive aggregate gross proceeds of at least $300 million from this offering and the Unsecured Financing we intend to borrow under the Unsecured Bridge Facility and/or issue unsecured notes to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act in order to finance the remaining Cash Consideration for the Modspace Acquisition.

The documentation governing the Unsecured Notes is expected to contain covenants that, among other things, limit WSII's and its restricted subsidiaries' ability to: (i) incur or guarantee additional indebtedness or issue preferred stock; (ii) pay dividends on, or make other distributions in respect of, their capital stock; (iii) purchase or redeem capital stock or subordinated indebtedness; (iv) make investments; (v) create liens or use assets as security; (vi) enter into agreements restricting such restricted subsidiary's ability to pay dividends, make loans, or transfer assets to us or other restricted subsidiaries; (vii) sell assets, including capital stock of subsidiaries; (viii) engage in transactions with affiliates; and (ix) consolidate or merge with or into other companies or transfer all or substantially all of their assets. The aforementioned restrictions will be subject to certain exceptions. The documentation for the Unsecured Notes is expected to also contain certain customary representations and warranties, conditions to borrowing and events of default.

The documentation governing the Unsecured Notes has not been finalized and accordingly, the actual terms of the Unsecured Notes may differ materially from those described in this prospectus supplement.

The gross proceeds to us from this offering will be $128.0 million (or $147.2 million if the underwriters exercise their option to purchase additional shares of Common Stock in full), at a public offering price of $16.00 per share.

We intend to use the gross proceeds from this offering, together with the gross proceeds of the Other Financing Transactions, to fund the Cash Consideration for the ModSpace Acquisition and to pay related fees and expenses.

There can be no assurance that the ModSpace Acquisition or any of the Other Financing Transactions will be consummated on the terms described herein, or at all. If the ModSpace Acquisition is not consummated, we intend to use the net proceeds of this offering for general corporate purposes.

The following table sets forth our cash and cash equivalents, total debt and capitalization at March 31, 2018:

This offering is not conditioned on the consummation of the Other Financing Transactions or the ModSpace Acquisition. The following data are qualified in their entirety by our financial statements and the related notes and other information incorporated by reference into this prospectus supplement and the accompanying prospectus. This table should be read in connection with the sections entitled "Summary—Recent Developments", "Risk Factors", and "Use of Proceeds" and each of our and ModSpace's consolidated financial statements and related notes thereto which are incorporated by

reference into this prospectus supplement and the accompanying prospectus. See "Where You Can Find More Information and Incorporation by Reference" in this prospectus supplement.

Our Common Stock is listed on Nasdaq under the symbol "WSC." Through November 29, 2017, our common stock, warrants, and units were quoted under the symbols "EAGL," "EAGLW" and "EAGLU," respectively. Upon consummation of our business combination with WSII, our public units automatically separated into their component securities and, as a result, no longer trade as a separate security. These units were delisted from Nasdaq.

The following table includes the high and low closing prices for shares of our Common Stock for the periods presented. Share prices for the fourth quarter of 2017 represent prices for Common Stock of WillScot Corporation which came into existence on November 29, 2017 as part of the business combination. Share prices for all other periods presented represent prices for Class A ordinary shares of Double Eagle.

The closing price of our Common Stock on Nasdaq on July 20, 2018 was $15.80. As of June 30, 2018, there were 8 registered stockholders of record of our Common Stock.

We have not paid any cash dividends on our Common Stock to date. The payment of cash dividends will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition. The determination of whether or not we pay any cash dividends from time to time is within the discretion of our board of directors. Further, our ability to declare dividends may be limited by restrictive covenants under our financing arrangements.

The following discussion describes material U.S. federal income tax considerations that are likely to be relevant to the purchase, ownership, and disposition of shares of our Common Stock. This discussion deals only with shares of our Common Stock held as capital assets, for U.S. federal income tax purposes, by investors who purchase shares of our Common Stock in this offering. This discussion does not cover all aspects of U.S. federal taxation that may be relevant to the purchase, ownership or disposition of shares of our Common Stock by prospective investors in light of their specific facts and circumstances. In particular, this discussion does not address all of the tax considerations that may be relevant to persons in special tax situations, including banks, insurance companies or other financial institutions, dealers in securities, persons that will hold more than 5% of our Common Stock, certain former citizens or long-term residents of the United States, a person that is a "controlled foreign corporation," a person that is a "passive foreign investment company," persons holding shares of our Common Stock as part of a hedge, straddle, conversion or other integrated financial transaction, entities or arrangements that are treated as partnerships for U.S. federal income tax purposes (or partners therein), persons subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an applicable financial statement or that are otherwise subject to special treatment under the Code. This section does not address any other U.S. federal tax considerations (such as estate or gift taxes, the alternative minimum tax or the Medicare tax on net investment income) or any state, local or non-U.S. tax considerations. You should consult your own tax advisors about the tax consequences of the purchase, ownership and disposition of shares of our Common Stock in light of your own particular circumstances, including the tax consequences under state, local, non-U.S. and other tax laws and the possible effects of any changes in applicable tax laws.

For purposes of this discussion, a "U.S. Holder" means a beneficial owner of shares of our Common Stock that is an individual citizen or resident of the United States, a domestic corporation or otherwise subject to U.S. federal income tax on a net basis with respect to income from our Common Stock. A "Non-U.S. Holder" means any beneficial owner of shares of our Common Stock that is an individual, corporation, foreign estate, or foreign trust that is not a U.S. Holder.

This discussion is based on the tax laws of the United States, including the Code, existing and proposed regulations, and administrative and judicial interpretations, all as of the date hereof. Such authorities may be repealed, revoked, modified or subject to differing interpretations, possibly on a retroactive basis, so as to result in U.S. federal income tax consequences different from those discussed below.

Dividends. A distribution of cash or property with respect to shares of our Common Stock generally will be treated as a dividend to the extent paid out of our current or accumulated earnings and profits and will be includible in income by the U.S. Holder and taxable as ordinary dividend income when received. If such a distribution exceeds our current and accumulated earnings and profits, the excess will be first treated as a tax-free return of the U.S. Holder's investment, and reduce the U.S. Holder's tax basis in the shares of our Common Stock (but not below zero), and thereafter as a capital gain from the sale or exchange of such Common Stock. Dividends received by a non-corporate U.S. Holder generally will be eligible to be taxed at reduced rates if the U.S. Holder meets certain holding period and other applicable requirements. Dividends received by a corporate U.S. Holder generally will be eligible for the dividends-received deduction if the U.S. Holder meets certain holding period and other applicable requirements.

Sale, Exchange or Other Taxable Disposition of Common Stock. For U.S. federal income tax purposes, gain or loss that a U.S. Holder realizes on the sale or other disposition of shares of our Common Stock will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder

held the shares for more than one year. The amount of the U.S. Holder's gain or loss will be equal to the difference between the amount realized on the disposition and the U.S. Holder's tax basis in the shares of our Common Stock that were sold. A U.S. Holder's tax basis in the Common Stock is generally its purchase price for the Common Stock. Long-term capital gains recognized by non-corporate U.S. Holders generally will be subject to tax at reduced rates. The deductibility of capital losses may be subject to limitations.

Dividends. A distribution of cash or property with respect to shares of our Common Stock generally will be treated as a dividend to the extent paid out of our current or accumulated earnings and profits. If such a distribution exceeds our current and accumulated earnings and profits, the excess will be first treated as a tax-free return of the non-U.S. Holder's investment, up to the non-U.S. Holder's tax basis in the shares of our Common Stock, and thereafter as a capital gain subject to the tax treatment described below in "—Sale, Exchange or Other Taxable Disposition of Common Stock."

Except as described below with respect to effectively connected dividends and subject to the discussion below under "Information Reporting and Backup Withholding," dividends paid to a Non-U.S. Holder generally will be subject to withholding of U.S. federal income tax at a 30% rate, or such lower rate as may be specified by an applicable tax treaty.

Even if a Non-U.S. Holder is eligible for a lower treaty rate, we generally will be required to withhold at a 30% rate (rather than the lower treaty rate) on dividend payments to a Non-U.S. Holder, unless:

If a Non-U.S. Holder is eligible for a reduced rate of U.S. federal withholding tax pursuant to an applicable income tax treaty or otherwise, the Non-U.S. Holder may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Investors are encouraged to consult with their own tax advisors regarding the possible implications of these withholding requirements on their investments in the shares of our Common Stock.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable

withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax generally in the same manner as if the Non-U.S. Holder were a U.S. person and will be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year that are attributable to such dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules or rates.

Sale, Exchange or Other Taxable Disposition of Common Stock. Subject to the discussion below under "Information Reporting and Backup Withholding," Non-U.S. Holders generally will not be subject to U.S. federal income tax with respect to gain recognized on a sale, exchange or other taxable disposition of shares of our Common Stock unless: (i) the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable); (ii) the Non-U.S. Holder is an individual who is present in the United States for a period or periods aggregating 183 days or more in the taxable year of that disposition and other conditions are met; or (iii) our Common Stock constitutes a U.S. real property interest ("USRPI") by reason of our status as a U.S. real property holding corporation ("USRPHC") for U.S. federal income tax purposes.

Gain described in (i) above generally will be subject to U.S. federal income tax in the same manner as if the Non-U.S. Holder were a U.S. person and will be subject to the U.S. federal income tax on the net gain derived from the sale or other taxable disposition under regular graduated U.S. federal income tax rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on a portion of its effectively connected earnings and profits for the taxable year that are attributable to such gain, as adjusted for certain items.

Gain described in (ii) above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder, provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

We believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance that we currently are not a USRPHC or that will not become a USRPHC in the future. Even if we are or were to become a USRPHC, our Common Stock will not be treated as a USRPI if our Common Stock is "regularly traded," as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually or constructively, 5% or less of our Common Stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition of, or the Non-U.S. Holder's holding period for, our Common Stock.

In the case of the sale or disposition of shares of our Common Stock on or after January 1, 2019, a Non-U.S. Holder may be subject to a 30% withholding tax on the gross proceeds of the sale or disposition under FATCA unless the requirements described in the last bullet point under "Dividends" above are satisfied. Investors are encouraged to consult with their own tax advisors regarding the possible implications of these withholding requirements on their investment in the shares of our Common Stock and the potential for a refund or credit in the case of any withholding tax.

Information returns are required to be filed with the IRS with respect to payments (including sales proceeds) made to certain holders. In addition, certain U.S. Holders may be subject to backup withholding tax in respect of such payments if they do not provide their taxpayer identification numbers to the paying agent, fail to certify that they are not subject to backup withholding tax, or otherwise fail to comply with applicable backup withholding tax rules. Non-U.S. Holders may be required to comply with applicable certification procedures to establish that they are Non-U.S. Holders in order to avoid the application of backup withholding tax. Any amount paid as backup withholding may be creditable against the holder's U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Barclays Capital Inc., Deutsche Bank Securities Inc., Morgan Stanley & Co. LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the number of shares indicated below:

The underwriters and the representatives are collectively referred to as the "underwriters" and the "representatives," respectively. The underwriters are offering the shares of Common Stock subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of Common Stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of Common Stock offered by this prospectus supplement if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters' option to purchase additional shares described below.

The underwriters initially propose to offer part of the shares of Common Stock directly to the public at the offering price listed on the cover page of this prospectus supplement and part to certain dealers. After the initial offering of the shares of Common Stock, the offering price and other selling terms may from time to time be varied by the representatives.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 1,200,000 additional shares of Common Stock at the public offering price listed on the cover page of this prospectus supplement, less underwriting discounts and commissions. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of Common Stock as the number listed next to the underwriter's name in the preceding table bears to the total number of shares of Common Stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions, and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase up to an additional 1,200,000 shares of Common Stock.

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately $0.4 million. We have agreed to reimburse the underwriters for expense relating to clearance of this offering with the Financial Industry Regulatory Authority, Inc. up to $15,000.

We and all directors and executive officers and Sapphire Holding S.á r.l., an entity controlled by TDR Capital, have agreed that, without the prior written consent of Barclays Capital Inc., Deutsche Bank Securities Inc., Morgan Stanley & Co. LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the underwriters, we and they will not, during the period ending 60 days after the date of this prospectus supplement (the "restricted period"):

whether any such transaction described above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. In addition, we and each such person agrees that, without the prior written consent of Barclays Capital Inc., Deutsche Bank Securities Inc., Morgan Stanley & Co. LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the underwriters, we or such other person will not, during the restricted period, make any demand for, or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.

The restrictions described in the immediately preceding paragraph to do not apply to:

Barclays Capital Inc., Deutsche Bank Securities Inc., Morgan Stanley & Co. LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated in their sole discretion, may release the Common Stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

In order to facilitate the offering of the Common Stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Common Stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the option. The underwriters can close out a covered short sale by exercising the option of purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option. The underwriters may also sell shares in excess of the option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Common Stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of Common Stock in the open market to stabilize the price of the Common Stock. These activities may raise or maintain the market price of the Common Stock above independent market levels or prevent or retard a decline in the market price of the Common Stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus supplement in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The

representative may agree to allocate a number of shares of Common Stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representative to underwriters that may make Internet distributions on the same basis as other allocations.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging. financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses. In particular, the underwriters, or their affiliates, have committed to provide the Secured Bridge Facility and the Unsecured Bridge Facility to the Company or its affiliates under certain circumstances, for which they will be paid customary fees. The commitment in respect of the Unsecured Bridge Facility will be reduced with certain proceeds of this offering in accordance with the terms of the ABL/Bridge Debt Commitment Letter, as further described in "Summary—The Transactions." Furthermore, affiliates of the underwriters, will act as lenders in respect of the ABL Facility and anticipated borrowings under the ABL Facility may be reduced by certain proceeds of this offering in accordance with the terms of the ABL/Bridge Debt Commitment Letter, as further described in "Summary—The Transactions."

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

In addition, we have granted the underwriters the right to participate in any public or private offering of securities by us, subject to certain limitations.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a "Relevant Member State") an offer to the public of any shares of our Common Stock may not be made in that Relevant Member State, except that an offer to the public in that Relevant Member State of any shares of our Common Stock may be made at any time under the following exemptions under the Prospectus Directive, if they have been implemented in that Relevant Member State:

For the purposes of this provision, the expression an "offer to the public" in relation to any shares of our Common Stock in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and any shares of our Common Stock to be offered so as to enable an investor to decide to purchase any shares of our Common Stock, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression "Prospectus Directive" means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in the Relevant Member State, and the expression "2010 PD Amending Directive" means Directive 2010/73/EU.

The Common Stock may be sold in Canada only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions, and Ongoing Registrant Obligations. Any resale of the Common Stock must be made in accordance with an exemption form, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province or territory of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

The Common Stock may not be offered or sold in Hong Kong by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32 of the Laws of Hong Kong), or Companies (Winding Up and Miscellaneous Provisions) Ordinance, or which do not constitute an invitation to the public within the meaning of the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong), or Securities and Futures Ordinance, or (ii) to "professional investors" as defined in the Securities and Futures Ordinance and any rules made thereunder, or (iii) in

other circumstances which do not result in the document being a "prospectus" as defined in the Companies (Winding Up and Miscellaneous Provisions) Ordinance, and no advertisement, invitation or document relating to the shares may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to shares of Common Stock which are or are intended to be disposed of only to persons outside Hong Kong or only to "professional investors" in Hong Kong as defined in the Securities and Futures Ordinance and any rules made thereunder.

This prospectus supplement has not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this prospectus supplement and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the shares of Common Stock may not be circulated or distributed, nor may the shares of Common Stock be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor under Section 274 of the Securities and Futures Act, Chapter 289 of Singapore (the "SFA") (ii) to a relevant person pursuant to Section 275(1), or any person pursuant to Section 275(1A), and in accordance with the conditions specified in Section 275, of the SFA, or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

No registration pursuant to Article 4, paragraph 1 of the Financial Instruments and Exchange Law of Japan (Law No. 25 of 1948, as amended) (the "FIEL") has been made or will be made with respect to the solicitation of the application for the acquisition of the shares of Common Stock.

Accordingly, the shares of Common Stock have not been, directly or indirectly, offered or sold and will not be, directly or indirectly, offered or sold in Japan or to, or for the benefit of, any resident of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan) or to others for re-offering or re-sale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan except pursuant to an exemption from the registration requirements, and otherwise in compliance with, the FIEL and the other applicable laws and regulations of Japan.

Please note that the solicitation for newly-issued or secondary securities (each as described in Paragraph 2, Article 4 of the FIEL) in relation to the shares of Common Stock constitutes either a "QII only private placement" or a "QII only secondary distribution" (each as described in Paragraph 1, Article 23-13 of the FIEL).

The consolidated financial statements of WillScot Corporation appearing in WillScot Corporation's Annual Report ("Form 10-K") for the year ended December 31, 2017, have been audited by Ernst & Young LLP ("EY"), independent registered public accounting firm, as set forth in their report thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such report given on the authority of such firm as experts in accounting and auditing.

Prior to the engagement of EY as WSII's independent registered public accounting firm under the standards of the Public Company Accounting Oversight Board ("PCAOB"), EY and other associated entities of Ernst & Young Global Limited ("EYG") had lending relationships with a 12.40% owner of WSII's parent company. The independent auditor having a lending relationship with a record or beneficial owner of greater than 10% of the outstanding shares of the parent of an audit client is not in accordance with the auditor independence rules of Regulation S-X and the PCAOB. All such lending relationships were terminated during 2015. The lending relationship did not affect the audit procedures or audit judgments in connection with the audits of WSII's consolidated financial statements.

Additionally prior to the engagement of EY as WSII's independent registered public accounting firm under the PCAOB standards, a member firm of EYG in Norway was engaged to provide a loan staffing service whereby an employee of such member firm acted in a management function from January 2015 through July 2015 for a controlled investee of TDR Capital LLP, the ultimate parent of WSII. The entity for whom the engagement was performed is an affiliate of WSII under the SEC independence rules by virtue of being under common control by the same ultimate parent. This service is prohibited under the auditor independence rules of Regulation S-X and the PCAOB. The service was not related to, and did not affect, the consolidated financial statements of WSII nor EY's related audits. Total fees collected by the EYG member firm for the loan staffing services were insignificant in relation to the total fees for EY's audits. None of the professionals who provided the service were members of the EY audit engagement team with respect to the audits of WSII's consolidated financial statements.

After careful consideration of the facts and circumstances and the applicable independence rules, EY has concluded that (i) the aforementioned matters do not impair EY's ability to exercise objective and impartial judgment in connection with its audits of WSII's consolidated financial statements and (ii) a reasonable investor with knowledge of all relevant facts and circumstances would conclude that EY has been and is capable of exercising objective and impartial judgment on all issues encompassed within its audits of WSII's consolidated financial statements. After considering these matters, WSII's management and the audit committee charged with governance over WSII concur with EY's conclusions.

The audited historical consolidated financial statements of Modular Space Holdings, Inc. as of September 30, 2017 and for the period from March 3, 2017 to March 31, 2017 ("Successor") included on Exhibit 99.1 of WillScot Corporation's Current Report on Form 8-K dated July 24, 2018 have been so incorporated in reliance on the report (which contains an explanatory paragraph relating to the Company's joint prepackaged plan of reorganization and emergence from bankruptcy, as described in Note 1 to the consolidated financial statements) of PricewaterhouseCoopers LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting.

The audited historical consolidated financial statements of Modular Space Holdings, Inc. as of September 30, 2016 and for the period from October 1, 2016 to March 2, 2017, and for each of the two years in the period ended September 30, 2016 ("Predecessor") included on Exhibit 99.1 of WillScot Corporation's Current Report on Form 8-K dated July 24, 2018 have been so incorporated in reliance

on the report (which contains an explanatory paragraph relating to the Company's joint prepackaged plan of reorganization and emergence from bankruptcy, as described in Note 1 to the financial statements) of PricewaterhouseCoopers LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting.

You should consider the specific risks described in the 2017 10-K, the risk factors described under the caption "Risk Factors" in any applicable prospectus supplement and any risk factors set forth in our other filings with the SEC, pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, before making an investment decision.

Based on the information currently known to us, we believe that the information incorporated by reference in this prospectus identifies the most significant risk factors affecting us. Each of risks described in these documents could materially and adversely affect its business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment.

The following table sets forth our ratio of consolidated earnings to fixed charges for each of the periods indicated. We do not have any Preferred Stock outstanding as of the date of this prospectus and did not have any Preferred Stock with required dividend payments during any of the periods presented below. Therefore, there are no preferred dividends included in our calculation of these ratios.

We intend to use the net proceeds from the sale of the securities as set forth in the applicable prospectus supplement.

This prospectus contains a summary of our Common Stock (as defined below), Preferred Stock, warrants, and debt securities. These summaries are not meant to be a complete description of each security. The particular terms of any security to be issued pursuant hereto will be set forth in a related prospectus supplement. This prospectus and the accompanying prospectus supplement will contain the material terms and conditions for each security.

The following is a description of our capital stock and certain provisions of our certificate of incorporation, bylaws and certain provisions of applicable law. The following is only a summary and is qualified by applicable law and by the provisions of our certificate of incorporation and bylaws, copies of which are included as exhibits to the registration statement of which this prospectus forms a part.

We are incorporated in the State of Delaware. The rights of our stockholders are generally covered by Delaware law and our certificate of incorporation and bylaws. The terms of our capital stock are therefore subject to Delaware law, including the Delaware General Corporation Law.

Our Certificate of Incorporation authorizes the issuance of 501,000,000 shares of capital stock, consisting of (i) 500,000,000 shares of common stock, including 400,000,000 shares of Class A Common Stock and 100,000,000 shares of Class B common stock (our "Class B Common Stock" and together with our Class A Common Stock, our "Common Stock") and (ii) 1,000,000 shares of Preferred Stock.

This section describes the general terms and provisions of our Common Stock. For more detailed information, you should refer to our Certificate of Incorporation and Bylaws, copies of which have been filed with the SEC. These documents are also incorporated by reference into the registration statement of which this prospectus forms a part.

The holders of shares of Common Stock possess all voting power for the election of our directors and all other matters requiring stockholder action and will at all times vote together as one class on all matters submitted to a vote of the stockholders of the Company. Holders of Common Stock are entitled to one vote per share on matters to be voted on by stockholders. Holders of Class A Common Stock will be entitled to receive dividends if and when declared by our Board out of funds legally available therefor and shall share equally on a per share basis in such dividends and distributions. Holders of Class B Common Stock are not entitled to share in any such dividends or other distributions. Upon liquidation, dissolution or winding-up of our Company, the holders of the Class A Common Stock will be entitled to receive an equal amount per share of all of our assets available for distribution, after the rights of the holders of any Preferred Stock have been satisfied. Holders of Class B Common Stock are not entitled to receive any portion of such assets in respect of their shares of Class B Common Stock. Our stockholders have no preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to our Common Stock.

This section describes the general terms and provisions of our Preferred Stock. For more detailed information, you should refer to our Certificate of Incorporation and Bylaws, copies of which have been filed with the SEC. These documents are also incorporated by reference into the registration statement of which this prospectus forms a part

Preferred Stock may be issued from time to time in one or more series. Our Board can fix the rights, preferences and privileges applicable to the shares of each series and any of its qualifications, limitations or restrictions. Our Board is authorized, without stockholder approval, to issue Preferred Stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Common Stock and could have anti-takeover effects. The ability of our Board to issue Preferred Stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no Preferred Stock outstanding at the date hereof.

Our board of directors will fix the designations, voting powers, preferences and rights of each series, as well as the qualifications, limitations or restrictions thereof, of the Preferred Stock of each series that we offer under this prospectus and applicable prospectus supplements in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of Preferred Stock we are offering before the issuance of that series of Preferred Stock. This description will include:

The General Corporation Law of the State of Delaware, the state of our incorporation, provides that the holders of Preferred Stock will have the right to vote separately as a class (or, in some cases, as a series) on an amendment to our certificate of incorporation if the amendment would change the par value or, unless the certificate of incorporation provided otherwise, the number of authorized shares of the class or change the powers, preferences or special rights of the class or series so as to adversely affect the class or series, as the case may be. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

We have outstanding warrants exercisable for 34,750,000 shares of Class A Common Stock, consisting of: (i) 50,000,000 warrants, each exercisable for one-half of one share of common stock issued in connection with Double Eagle's (as defined below)initial public offering (the "Public Warrants") and (ii) 19,500,000 warrants, each exercisable for one-half of one share of common stock (the "Private Warrants," and together with the Public Warrants, the "Existing Warrants"). The Existing Warrants were issued under a warrant agreement dated September 10, 2015, between Continental Stock Transfer & Trust Company, as warrant agent, and Double Eagle Acquisition Corp., our predecessor company ("Double Eagle").

Each Public Warrant entitles the registered holder to purchase one-half of one share of our Class A Common Stock at a price of $5.75 per half share, subject to adjustment, at any time. The Public Warrants will expire on November 29, 2022, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We may call the Public Warrants for redemption in whole and not in part, at a price of $0.01 per warrant, upon not less than 30 days' prior written notice of redemption to each warrant holder and if, and only if, the last reported sale price of the Class A Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before we send the notice of redemption to the warrant holders.

The Public Warrant holders do not have the rights or privileges of holders of Class A Common Stock and any voting rights until they exercise their Public Warrants and receive shares of Class A Common Stock. After the issuance of shares of Class A Common Stock upon exercise of the Public Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Public Warrants may be exercised only for a whole number of shares of Class A Common Stock. No fractional shares will be issued upon exercise of the Public Warrants. If, upon exercise of the Public Warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise,

round down to the nearest whole number the number of shares of Class A Common Stock to be issued to the Public Warrant holder.

The founders of Double Eagle and our former independent directors purchased 19,500,000 Private Warrants at a price of $0.50 per Private Warrant for an aggregate purchase price of $9,750,000 in a private placement that occurred simultaneously with Double Eagle's initial public offering. The Private Warrants may be exercised at any time. So long as the Private Warrants are held by the initial shareholders or their permitted transferees, such warrants may be exercised on a cashless basis and will not be redeemable by us. If the Private Warrants are held by holders other than the initial shareholders or their permitted transferees, the Private Warrants will be redeemable by us and exercisable by the holders on the same basis as the Public Warrants. Otherwise, the Private Warrants have terms and provisions that are identical to those of the Public Warrants.

In addition, pursuant to the terms of the Earnout Agreement, all of the Private Warrants held by the founders of our predecessor Double Eagle Acquisition Corp., including Jeff Sagansky (14,550,000 Private Warrants) are subject to transfer restrictions until November 29, 2018, among other terms, and may not be exercised until the expiration of such restrictions under the Earnout Agreement.

On November 29, 2017, we entered into an amended and restated registration rights agreement pursuant to which we granted to TDR Capital, the founders of our predecessor Double Eagle Acquisition Corp. and the other parties named therein, certain demand, shelf and piggyback registration rights covering all shares of our Class A Common Stock owned by each holder, until such shares cease to be "Registrable Securities" (as defined therein).

Our Class A Common Stock and warrants are listed on Nasdaq under the symbols "WSC" and "WSCWW," respectively.

The transfer agent and registrar for our Class A Common Stock is Continental Stock Transfer & Trust Company. Its address is 1 State Street, 30th Floor, New York, NY 10004. The transfer agent for any series of Preferred Stock that we may offer under this prospectus will be named and described in the prospectus supplement for that series.

We may issue warrants for the purchase of our Class A Common Stock, Preferred Stock or debt securities. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under one or more warrant agreements to be entered into between us and a warrant agent to be named in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include the following:

Each warrant will entitle the holder of the warrant to purchase for cash the amount of common stock, preferred stock or debt securities at the exercise price stated or determinable in the applicable prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as possible, forward the common stock, preferred stock or debt securities that the warrant holder has purchased. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants.

The description in the applicable prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement and warrant certificate, which will be filed with the SEC if we offer warrants. For more information on how you can obtain copies of any warrant certificate or warrant agreement if we offer warrants, see "Where You Can Find More Information" beginning on page 2 of this prospectus. We urge you to read the applicable warrant certificate, the applicable warrant agreement and any applicable prospectus supplement in their entirety.

Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements will be governed by and construed in accordance with the laws of the State of New York.

We may offer secured or unsecured debt securities which may be senior or subordinated, and which may be convertible or non-convertible, exchangeable or non-exchangeable. We may issue debt securities in one or more series.

The following description briefly sets forth certain general terms and provisions of the debt securities that we may offer and sell from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to the debt securities, will be described in the applicable prospectus supplement. A form of the indenture is filed as an exhibit to the registration statement of which this prospectus forms a part. The terms of the debt securities will include those set forth in the applicable indenture, any related security documents and those made a part of the applicable indenture by the Trust Indenture Act of 1939, as amended (the "TIA"). You should read the summary below, the applicable prospectus supplement and the provisions of the applicable indenture and any related security documents, if any, in their entirety before investing in our debt securities. Capitalized terms used in the summary have the meanings specified in the indentures.

The prospectus supplement relating to any series of debt securities that we may offer will contain the specific terms of the debt securities. These terms may include the following:

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the applicable indenture. In addition, we will describe in the applicable prospectus supplement, material U.S. federal income tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $1,000 and any integral multiples thereof. Subject to the limitations provided in the indenture and in the prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the corporate office of the trustee or the principal corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Unless we inform you otherwise in the applicable prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be

transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

The indenture and the debt securities shall be construed in accordance with and governed by the laws of the State of New York.

We may sell the securities offered by this prospectus from time to time in one or more transactions, including without limitation:

We will identify the specific plan of distribution, including any underwriters, brokers, dealers, agents or direct purchasers and their compensation in a prospectus supplement, in a post-effective amendment, or in filings we make with the SEC under the Exchange Act which are incorporated by reference.

A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, subscriptions, exchangeable securities, forward delivery contracts and the writing of options.

In addition, the manner in which we may sell some or all of the securities covered by this prospectus, includes, without limitation, through:

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement or pricing supplement, as the case may be. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities

pursuant to this prospectus and the applicable prospectus supplement or pricing supplement, as the case may be.

Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be "underwriters" as defined in the Securities Act. Any discounts or commissions they receive from us and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.

If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market price or at negotiated prices. We may offer the securities to the public through an underwriting syndicate or through a single underwriter. The underwriters in any particular offering will be mentioned in the applicable prospectus supplement or pricing supplement, as the case may be.

Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

We may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. We may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for us. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

We may sell the offered securities to dealers as principals. We may negotiate and pay dealers' commissions, discounts or concessions for their services. The dealer may then resell such securities to

the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale. Dealers engaged by us may allow other dealers to participate in resales.

We may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved.

We may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or pricing supplement, as the case may be will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

We will enter into such delayed contracts only with institutional purchasers that we approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

We may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.

There is currently no market for any of the offered securities, other than the Class A Common Stock and the Existing Warrants which are listed for trading on Nasdaq. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We have no current plans for listing of the debt securities, preferred stock or warrant on any securities exchange; any such listing with respect to any particular debt securities, preferred stock or warrant will be described in the applicable prospectus supplement or pricing supplement, as the case may be.

In connection with any offering of Class A Common Stock, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the over-allotment option. The underwriters must close out

any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.

In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc. ("FINRA"), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement or pricing supplement, as the case may be; however, it is anticipated that the maximum commission or discount to be received in any particular offering of securities will be significantly less than this amount.

Unless otherwise indicated in the applicable prospectus supplement, Allen & Overy LLP, New York, New York will provide opinions regarding the authorization and validity of the securities. Allen & Overy LLP may also provide opinions regarding certain other matters. Any underwriters will also be advised about legal matters by their own counsel, which will be named in the prospectus supplement..

The consolidated financial statements of WillScot Corporation appearing in the Company's Annual Report (Form 10-K) for the year ended December 31, 2017 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their report thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such report given on the authority of such firm as experts in accounting and auditing.

Prior to the engagement of EY as WSII's independent registered public accounting firm under the standards of the Public Company Accounting Oversight Board ("PCAOB"), EY and other associated entities of Ernst & Young Global Limited ("EYG") had lending relationships with a 12.40% owner of WSII's former parent company. The independent auditor having a lending relationship with a record or beneficial owner of greater than 10% of the outstanding shares of the parent of an audit client is not in accordance with the auditor independence rules of Regulation S-X and the PCAOB. All such lending relationships were terminated during 2015. The lending relationship did not affect the audit procedures or audit judgments in connection with the audits of WSII's consolidated financial statements.

service is prohibited under the auditor independence rules of Regulation S-X and the PCAOB. The service was not related to, and did not affect, the consolidated financial statements of WSII nor EY's related audits. Total fees collected by the EYG member firm for the loan staffing services were insignificant in relation to the total fees for EY's audits. None of the professionals who provided the service were members of the EY audit engagement team with respect to the audits of WSII's consolidated financial statements.

After careful consideration of the facts and circumstances and the applicable independence rules, EY has concluded that (i) the aforementioned matters do not impair EY's ability to exercise objective and impartial judgment in connection with its audits of WSII's consolidated financial statements and (ii) a reasonable investor with knowledge of all relevant facts and circumstances would conclude that EY has been and is capable of exercising objective and impartial judgment on all issues encompassed within its audits of WSII's consolidated financial statements. After considering these matters, WillScot Corporation's management and the audit committee charged with governance over WSII concur with EY's conclusions.
