UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information sets forth selected pro forma consolidated financial information for WillScot Corporation (the “Company,” “WillScot” or “we,” “us,” or “our”) for the year ended December 31, 2017 and the six months ended June 30, 2018 and is derived from and should be read in conjunction with, the consolidated financial statements and related notes in our Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 10-K”), the consolidated financial statements and related notes in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2018 (the “Q2 2018 10-Q”), and ModSpace Holdings, Inc.’s (“ModSpace”) historical consolidated financial statements included as Exhibits 99.1 and 99.2 to our Current Report on Form 8-K filed on July 24, 2018 and ModSpace’s historical consolidated financial statements included as Exhibit 99.1 and Exhibit 99.2 to our Current Report on Form 8-K/A filed on September 17, 2018.

On August 15, 2018, pursuant to the terms of that certain Agreement and Plan of Merger (the “Merger Agreement”) dated as of June 21, 2018, by and among WillScot Corporation, a Delaware corporation (the “Company”), the Company’s newly-formed acquisition subsidiary, Mason Merger Sub, Inc., a Delaware corporation (“Merger Sub”), ModSpace, and NANOMA LLC, solely in its capacity as the representative of the Holders (as defined therein), Merger Sub merged with and into ModSpace (the “Merger”) with ModSpace as the surviving entity in the Merger and continuing as an indirect subsidiary of the Company (the “ModSpace Acquisition”). The unaudited pro forma condensed combined financial information set forth below has been prepared to reflect adjustments to our financial condition and results of operations to give effect to the following items:

i.                  the consummation of the ModSpace Acquisition, including our issuance of shares of our Class A common stock, par value $0.0001 per share (the “Common Stock”), and warrants to purchase shares of Common Stock (the “ModSpace Warrants”) to the sellers of ModSpace;

ii.               the Financing Transactions (as defined and discussed below),

iii.            the effects of the acquisition of Acton Mobile Holdings, LLC (“Acton”), which closed on December 20, 2017 (the “Acton Acquisition”);

iv.           the effects of the business combination of Double Eagle Acquisition Corp. and Williams Scotsman International, Inc., which we completed on November 29, 2017 (the “Business Combination”), on the historical capital structure; and

v.              Transaction costs incurred in connection with the ModSpace Acquisition and Financing Transactions.

As referred to above, the “Financing Transactions” includes:

·                    our issuance of 9,200,000 shares of our Common Stock in an underwritten public offering at $16.00 per share (the “Equity Offering”);

·                    the entry by our indirect subsidiary, Williams Scotsman International, Inc. (“WSII”) and certain of its subsidiaries into amendments (the “Amended ABL Facility”) to the 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 became effective upon the closing of the ModSpace Acquisition and increased borrowing capacity under the ABL Facility from $600 million to $1.425 billion, with an accordion feature allowing aggregate borrowing capacity of up to $1.8 billion. As of the closing date of the ModSpace Acquisition, we have total borrowings of $841.1 million under the ABL Facility;

·                    WSII’s issuance of $300 million in aggregate principal amount of senior secured notes (the “Secured Notes”) to qualified institutional buyers pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”) (the “Secured Notes Offering”); and

·                    WSII’s issuance of $200 million in aggregate principal amount of senior unsecured notes (the “Unsecured Notes”) in a private placement transaction (the “Unsecured Financing”).

We refer to the entry into the Amended ABL Facility and the amounts funded thereunder, the Secured Notes Offering and the Unsecured Financing collectively as the “Other Financing Transactions.” We refer to the Equity

1

Offering and the Other Financing Transactions collectively as the “Financing Transactions.” We refer to the ModSpace Acquisition, the Acton Acquisition, the Business Combination and the Financing Transactions collectively as the “Transactions.”

In connection with our entry into the Merger Agreement and pursuant to an amended and restated commitment letter (as amended, 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, as amended, the Lenders provided (i) an incremental ABL loan facility in an aggregate principal amount of up to $825.0 million); (ii) a senior secured bridge loan facility in an aggregate principal amount of up to $285.6 million) (the “Secured Bridge Facility”); and (iii) a senior unsecured bridge loan facility in an aggregate principal amount of up to $326.4 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. We did not make any borrowings under the Unsecured Bridge Facility or the Secured Bridge Facility.

In connection with our entry into the Merger Agreement on July 31, 2018, a wholly-owned subsidiary of WSII, Mason Finance Sub, Inc. (“Finance Sub”), entered into a purchase agreement with certain financial institutions under which the initial purchasers agreed to purchase $300.0 million in aggregate principal amount of 6.875% senior secured notes due 2023 (the “2023 Secured Notes”) to be issued by Finance Sub. On August 6, 2018, Finance Sub closed the private placement and the initial purchasers deposited $300.0 million of gross offering proceeds into an escrow account. Upon consummation of the ModSpace Acquisition and the satisfaction of other conditions, the escrowed proceeds were released to fund a portion of the cash consideration payable by WSII in the ModSpace Acquisition and to pay related fees and expenses. Upon the closing the ModSpace Acquisition, Finance Sub merged with and into WSII, with WSII continuing as the surviving corporation, and WSII assumed the obligations of Finance Sub under the 2023 Secured Notes and the indenture governing the notes. The 2023 Secured Notes mature on August 15, 2023. The notes bear interest at a rate of 6.875% per annum, payable semi-annually on February 15 and August 15 of each year beginning February 15, 2019.

In connection with our entry into the Merger Agreement and 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 purchased senior unsecured notes (the “Unsecured Notes”) in an aggregate principal amount of $200.0 million, 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. The Unsecured Notes will mature on November 15, 2023. 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 any interest period ending on or prior to February 15, 2021, increasing thereafter to 12.5% per annum with no paid in kind option, in each case payable semi-annually on February 15 and August 15 of each year beginning February 15, 2019. The Unsecured Notes are WSII’s general unsecured obligations and 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.

In connection with the Other Financing Transactions and the ModSpace Acquisition, we and the Lenders entered into three amendments to the credit agreement governing our ABL loan facility to effectuate, among other

2

things, (i) the amendments contemplated by the ABL/Bridge Debt Commitment Letter, (ii) the syndication of the upsized ABL loan facility, and (iii) the closing of the ModSpace Acquisition, including the release of escrowed proceeds from the Secured Notes Offering and Unsecured Financing for purposes of funding the cash consideration payable in the Merger and transaction costs related thereto.

The following unaudited pro forma condensed combined financial information is based on the historical financial statements of WillScot, Acton and ModSpace described below. Our fiscal year is different than ModSpace’s historical fiscal year. Our fiscal year ends on December 31, while ModSpace’s historical fiscal year ends on September 30. In preparing the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2017, certain historical financial information for ModSpace was reclassed to align with WillScot’s annual reporting period. To adjust the historical operating results of ModSpace’s September fiscal year, we added the operating results for the three months ended December 31, 2017 (Successor), and subtracted the operating results for the three months ended December 31, 2016 (Predecessor) from the year ended September 30, 2017 for ModSpace Statement of Operations, to arrive at the reclassed statement of operations for the twelve months ended December 31, 2017 for ModSpace. To derive the historical operating results of ModSpace for the six months ended June 30, 2018, we subtracted the operating results for the three months ended December 31, 2017 (Successor) from the nine months ended June 30, 2018 for ModSpace Statement of Operations as filed in our Current Report on Form 8-K/A on September 17, 2018, to arrive at the reclassed statement of operations for the six months ended June 30, 2018. The ModSpace operating results for the three months ended December 31, 2017 are derived from the historical unaudited interim financial statements of ModSpace included in our Current Report on Form 8-K filed on July 24, 2018. The three month period was derived by taking the ModSpace historical unaudited statement of operations for the six month ended March 31, 2017, and subtracting the three months ended March 31, 2017. In addition, certain reclassifications were made to the reported financial information of ModSpace to conform to the reporting classifications of WillScot.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2017 combines:

·                    the audited historical consolidated statement of operations of Willscot for the year ended December 31, 2017;

·                    the reclassed unaudited historical consolidated statement of operations of ModSpace for the twelve months ended December 31, 2017; and

·                    the unaudited historical consolidated statement of operations of Acton for the period from January 1, 2017 to December 20, 2017.

The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2018 combines:

·                    the unaudited historical consolidated statement of operations of WillScot for the six months ended June 30, 2018 (historical statements include Acton operating results as it was a wholly owned subsidiary of WillScot during this period); and

·                    the reclassed unaudited historical consolidated statement of operations of ModSpace for the six months ended June 30, 2018.

The unaudited pro forma condensed combined balance sheet as of June 30, 2018 combines:

·                    the unaudited historical consolidated balance sheet of WillScot as of June 30, 2018 (historical statements include Acton as it was a wholly owned subsidiary of WillScot during this period); and

·                    the unaudited historical consolidated balance sheet of ModSpace as of June 30, 2018.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2017 is based on, derived from, and should be read in conjunction with, our historical audited financial statements as set forth in our 2017 10-K. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2017 is also based on, derived from, and reclassed from ModSpace’s historical audited financial statements for the fiscal year ended September 30, 2017 and should be read in conjunction with ModSpace’s

historical audited financial statements included in our Current Report on Form 8-K filed on July 24, 2018, as adjusted to conform to our calendar year end. The unaudited pro forma condensed statement of operations for the year ended December 31, 2017 does not include the operating results of Tyson Onsite (“Tyson”), which we acquired on January 3, 2018.

Our balance sheet as of June 30, 2018 and our statement of operations for the six months ended June 30, 2018 is based on, derived from, and should be read in conjunction with, our historical unaudited financial statements, included in our 10-Q for the quarter ended June 30, 2018.  ModSpace’s balance sheet as of June 30, 2018 and statement of operations for the six months ended June 30, 2018 is based on, and derived from, ModSpace’s historical unaudited financial statements, and should be read in conjunction with, ModSpace’s historical unaudited financial statements for the six months ended March 31, 2018 and the nine months ended June 30, 2018, included in our Current Report on Form 8-K filed on July 24, 2018 and our Current Report on Form 8-K/A filed on September 17, 2018, respectively.

The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2017, and the six months ended June 30, 2018 assume that the Transactions occurred on January 1, 2017. The unaudited pro forma condensed combined balance sheet as of June 30, 2018 assumes that the Transactions occurred on June 30, 2018. The unaudited pro forma condensed combined financial information has been prepared by management for illustrative purposes only and is not necessarily indicative of the consolidated financial position or results of operations that would have been realized had the Transactions occurred as of the dates indicated, nor is it meant to be indicative of any anticipated consolidated financial position or future results of operations of the combined company. In addition, the accompanying unaudited pro forma condensed combined statements of operations do not include any expected cost savings or restructuring actions which may be achievable or which may occur subsequent to the ModSpace Acquisition, or the costs to achieve these cost savings or restructuring actions. The pro forma financial information also does not include the impact of any non-recurring activity and one-time transaction-related costs. The historical consolidated financial information has been adjusted in the accompanying unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (i) directly attributable to the Transactions related thereto, (ii) factually supportable and (iii) with respect to the unaudited pro forma condensed combined statements of operations, are expected to have a continuing impact on the combined results. Please see note 4 below for further discussion of the pro forma adjustment.

The ModSpace Acquisition will be accounted for as a business combination using the acquisition method of accounting under the provisions of Accounting Standard Codification No. 805, “Business Combinations,” (“ASC 805”) and applying the pro forma assumptions and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial statements. Under ASC 805, the Company values assets acquired and liabilities assumed in a business combination at their fair values as of the acquisition date. Fair value measurements can be highly subjective and the reasonable application of measurement principles may result in a range of alternative estimates using the same facts and circumstances. The process for estimating the fair values of identifiable intangible assets and certain tangible assets requires the use of significant estimates and assumptions by management, including estimating future cash flows, and developing appropriate discount rates. Under ASC 805, transaction costs are not included as a component of consideration transferred, and are expensed as incurred. The final valuation is expected to be completed as soon as practicable but no later than one year after the consummation of the ModSpace Acquisition. The purchase price allocation is subject to completion of the Company’s final analysis of the fair value of the assets and liabilities of ModSpace as of the effective date of the ModSpace Acquisition. Accordingly, the purchase price allocation in the unaudited pro forma condensed combined financial statements is preliminary. Adjustments to the preliminary purchase price allocation could be material. The Company believes the fair values assigned to the assets to be acquired and liabilities to be assumed are based on reasonable estimates and assumptions using currently available data.

This unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X.  The unaudited pro forma condensed combined financial information is presented for informational purposes only and does not purport to represent what the Company’s results of operations would actually have been if the Transactions had occurred on the dates indicated nor do they purport to project the Company’s results of operations for any future period.

1. ModSpace Acquisition

On August 15, 2018, pursuant to the terms of the Merger Agreement dated as of June 21, 2018, we completed the ModSpace Acquisition. Subject to adjustments contemplated by the Merger Agreement, including a net working capital adjustment, the aggregate consideration paid to the sellers of ModSpace in connection with the ModSpace Acquisition consisted of (i) $1,063,750 in cash (the “Cash Consideration”), (ii) 6,458,500 shares of the Company’s Common Stock (the “Common Stock Consideration”), (iii) warrants to purchase an aggregate of 10,000,000 shares of the Company’s Common Stock at an exercise price of $15.50 per share (the “ModSpace Warrants”), and (iv) $5,724 in cash net working capital paid to seller.

The following table summarizes the components of the estimated total purchase price included in the pro forma condensed combined financial statements as if the acquisition had been completed on June 30, 2018:

(1)         Fair value of the ModSpace Warrants was preliminarily determined utilizing a Black-Scholes model resulting in a $3.91 per warrant fair value. The warrant fair value determination is preliminary, subject to management’s final determination and based on the Company’s Common Stock per share closing price on NASDAQ of $15.78 on August 15, 2018.

The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting under the provisions of ASC 805 and was based on the historical financial information of WillScot and ModSpace. Under the acquisition method of accounting, the total estimated purchase price of an acquisition is allocated to the net tangible and intangible assets to be acquired based on their estimated fair values as of the date the acquisition is consummated. Such fair values are based on available information and certain assumptions that we believe are reasonable. Management has made a preliminary allocation of the estimated purchase price to the tangible (including rental equipment) and intangible assets to be acquired and liabilities to be assumed based on various preliminary estimates. The final determination of these estimated fair values, the assets’ useful lives and the amortization methods are subject to completion of an ongoing assessment and will be available as soon as practicable but no later than one year after the consummation of the ModSpace Acquisition. Fair value measurements can be highly subjective and the reasonable application of measurement principles may result in a range of alternative estimates using the same facts and circumstances. The results of the final allocation could be materially different from the preliminary allocation set forth in these unaudited pro forma condensed combined financial statements, including but not limited to, the allocations related to identifiable intangible assets, rental equipment, property, plant and equipment, inventories, deferred taxes, goodwill, other depreciation and amortization, interest expense and income taxes:

Under the Merger Agreement, certain assets and liabilities will not transfer to us. Accordingly, pro forma adjustments have been reflected in the unaudited pro forma condensed combined balance sheet to exclude these net liabilities from the purchase price allocation of the acquired business:

The following table summarizes the preliminary purchase price allocation. ModSpace emerged from bankruptcy in March 2017 applying fresh start accounting which resulted in a revaluing of its balance sheet at the time. Based on preliminary valuation procedures which are subject to completion upon the closing, limited fair value adjustments were identified given the close proximity to the application of fresh start accounting. The table reflects the allocation of fair value as if the ModSpace Acquisition had been completed on June 30, 2018:
