Explanatory Note

This Current Report on Form 8-K/A is filed as an amendment (this “Amended Form 8-K”) to the Current Report on Form 8-K filed on March 1, 2021 (the “Original Form 8-K” ) by WillScot Mobile Mini Corp. (the “Company”) in order to reflect certain changes to the pro forma financial information contained in Item 9.01 of the Original Form 8-K due to the Restatement (as defined below).

On May 10, 2021, the Company filed an amendment to its Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 26, 2021 (the “Form 10-K/A”) to restate its financial statements (the “Restatement”) to conform with the SEC staff’s April 12, 2021 Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”) (the “SEC Statement”). The SEC Staff Statement addressed certain accounting and reporting considerations related to warrants of a kind similar to those issued by the Company that preclude the Company’s warrants from being classified as components of equity for certain reporting periods. The Company’s financial statements previously accounted for these warrants as components of equity. The financial statements were amended to account for these warrants as liabilities.

The Original Form 8-K is amended by this Amended Form 8-K to file the amended unaudited pro forma condensed combined financial statements of WillScot Mobile Mini Corp. for the year ended December 31, 2020 as Exhibit 99.1.

Item 8.01    Other Events.
As previously disclosed, on March 1, 2020, WillScot Corporation, a Delaware corporation (“WillScot”), Mobile Mini, Inc., a Delaware corporation (“Mobile Mini”), and Picasso Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of WillScot (“Merger Sub”), entered into an Agreement and Plan of Merger pursuant to which, subject to the satisfaction of certain customary closing conditions, Merger Sub would be merged with and into Mobile Mini, with Mobile Mini surviving as a wholly-owned subsidiary of WillScot (the “Merger”). The Merger was completed on July 1, 2020, upon which Merger Sub merged with and into Mobile Mini and the separate corporate existence of Merger Sub ceased and Mobile Mini continued its existence as the surviving corporation in the Merger and a wholly-owned subsidiary of WillScot. Immediately following the Merger, on July 1, 2020, WillScot changed its name to WillScot Mobile Mini Holdings Corp.
This Current Report on Form 8-K is being filed to provide certain pro forma financial information giving effect to the Merger for the year ended December 31, 2020, as set forth under Item 9.01(b) below, which is incorporated herein by reference.

Document
Exhibit 99.1
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 Mobile Mini Holdings Corp. (“WillScot Mobile Mini” or “the Company”) for the year ended December 31, 2020 and is derived from, and should be read in conjunction with, the consolidated financial statements and related notes in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2020 (the “2020 10-K/A”) and Mobile Mini, Inc.’s (“Mobile Mini”) historical consolidated financial statements included as Exhibits 99.1 and 99.2 to our Current Report on Form 8-K filed on August 10, 2020.
WillScot Corporation, a Delaware corporation (“WillScot”) entered into an Agreement and Plan of Merger, dated as of March 1, 2020, as amended on May 28, 2020 (as amended, the “Merger Agreement”), by and among WillScot, Mobile Mini, and Picasso Merger Sub, Inc., a wholly-owned subsidiary of WillScot (“Merger Sub”). On July 1, 2020, Merger Sub merged with and into Mobile Mini (the “Merger”). At the effective time of the Merger, the separate corporate existence of Merger Sub ceased, and Mobile Mini continued its existence as the surviving corporation in the Merger and a wholly-owned subsidiary of WillScot. As a result of the Merger, each issued and outstanding share of Mobile Mini Common Stock, par value $0.01 per share (other than treasury shares held by Mobile Mini), was converted automatically into the right to receive 2.405 shares of WillScot’s Class A Common Stock, par value $0.0001 per share (the “WillScot Class A Common Stock”), and cash in lieu of any fractional shares. Immediately following the Merger, WillScot changed its name to “WillScot Mobile Mini Holdings Corp.” and filed an amended and restated certificate of incorporation (the “A&R Charter”), which reclassified all outstanding shares of WillScot Class A Common Stock and converted such shares into shares of WillScot Mobile Mini common stock, par value $0.0001 per share (“WillScot Mobile Mini Common Stock”). Unless the context otherwise requires, all references herein to “WillScot,” refer to WillScot Corporation, at or prior to the completion of the Merger and without giving effect to the name change and all references to “WillScot Mobile Mini,” refer to WillScot Mobile Mini Holdings Corp., after giving effect to the Merger and the name change.
Upon completion of the Merger, each outstanding and unexercised option to purchase shares of Mobile Mini Common Stock was assumed by WillScot Mobile Mini and became an option to purchase shares of WillScot Mobile Mini Common Stock, on the same terms and conditions as applied to each such option immediately prior to the Merger, except that (A) the number of shares of WillScot Mobile Mini Common Stock subject to such option equaled the product of (i) the number of shares of Mobile Mini Common Stock that were subject to such option immediately prior to the Merger multiplied by (ii) 2.4050, rounded down to the nearest whole share, and (B) the per-share exercise price was equal to the quotient of (i) the exercise price per share of Mobile Mini Common Stock at which such option was exercisable immediately prior to the Merger, divided by (ii) 2.4050, rounded up to the nearest whole cent.
On July 1, 2020, in connection with the completion of the Merger, Williams Scotsman Holdings Corp (“WSHC”), Williams Scotsman International Inc. (“WSII”), and certain of its subsidiaries, entered into a new asset-based credit agreement that provides for revolving credit facilities in the aggregate principal amount of up to $2.4 billion, consisting of: (i) a senior secured asset-based US dollar revolving credit facility in the aggregate principal amount of $2.0 billion (the “US Facility”) and (ii) a $400.0 million senior secured asset-based multicurrency revolving credit facility (the “Multicurrency Facility” and together with the US Facility, the “2020 ABL Facility”). On July 1, 2020, in connection with the completion of the Merger, approximately $1.47 billion of proceeds from the 2020 ABL Facility were used to repay the existing WillScot revolving credit facility (“WillScot ABL Facility”) and the Mobile Mini revolving credit facility assumed in the Merger (“Mobile Mini ABL Facility”), as well as, to pay fees, costs, and expenses incurred in connection with the Merger and the related debt financing transactions.
In anticipation of the Merger, on June 15, 2020 Picasso Finance Sub, Inc., a newly-formed finance subsidiary of WSII and Delaware corporation (the “Escrow Issuer”), completed a private offering of $650.0 million in aggregate principal amount of its 6.125% senior secured notes due 2025 (the “2025 Secured Notes”). On July 1, 2020, the Escrow Issuer merged with and into WSII, with WSII as the surviving entity in such merger (the “Escrow Issuer Merger”). In connection with the Escrow Issuer Merger, WSII, each of WSII’s direct and indirect domestic subsidiaries and Williams Scotsman Holdings Corp. (together with the direct and indirect domestic subsidiaries of WSII (including Mobile Mini and its domestic subsidiaries), the “Note Guarantors”) and the Trustee entered into a supplemental indenture (the “2025 Secured Notes Indenture”) pursuant to which WSII assumed all of the Escrow Issuer’s obligations and rights under the 2025 Secured Notes Indenture and the Note Guarantors unconditionally guaranteed the 2025 Secured Notes. The offering proceeds from the 2025 Secured Notes were used to redeem all WillScot outstanding senior secured notes due 2022 (the “2022 Secured Notes”), redeem the existing Mobile Mini outstanding notes due 2024 assumed in the Merger (“Mobile Mini 2024 Notes”), and pay certain fees, costs, and expenses related to the Merger and the related financing transactions.
On June 30, 2020, as contemplated by the Merger Agreement, Sapphire Holding S.a r.l. (“Sapphire Holding”) exchanged each of its shares of common stock of WSHC for 1.3261 shares of WillScot Class A Common Stock (the “Sapphire Exchange”). As a result of the Sapphire Exchange, all issued and outstanding shares of WillScot's Class B Common Stock, par value $0.0001 per share, were automatically canceled for no consideration and the existing exchange agreement was automatically terminated. As a result of the Sapphire Exchange, Sapphire Holding became a wholly-owned subsidiary of WillScot. Prior to the Sapphire Exchange, Sapphire Holding’s ownership of WSHC was recorded as a non-controlling interest in the Company’s consolidated financial statements.

Exhibit 99.1
The following unaudited pro forma condensed combined financial information has been prepared to reflect adjustments to the results of operations of WillScot Mobile Mini to give effect to the following items:
i.the estimated effects of the Merger, inclusive of the effects of the assumption and subsequent repayment of the Mobile Mini ABL Facility and Mobile Mini 2024 Notes, both of which are deemed to be debt assumed as of the acquisition date;
ii.the extinguishment of the WillScot ABL Facility and a contemporaneous arrangement to enter into the 2020 ABL Facility, with an increased commitment;
iii.the issuance of the 2025 Secured Notes to qualified institutional buyers in a private placement transaction and the use of the proceeds therefrom and the extinguishment of the 2022 Secured Notes; and
iv.elimination of non-controlling interest as a result of the exchange of all issued and outstanding shares of the Company’s common stock held by Sapphire Holding for newly-issued shares of WillScot Class A Common Stock, as provided by the Merger Agreement (collectively with items above, the “Transactions”).
The following unaudited pro forma condensed combined financial information is based on the historical financial statements of WillScot Mobile Mini and Mobile Mini described below. In preparing the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020, certain reclassifications were made to the reported financial information of Mobile Mini to conform to the reporting classifications of the Company.
The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 assumes that the Transactions occurred on January 1, 2020. The unaudited pro forma condensed combined financial information has been prepared by WillScot Mobile Mini management for illustrative purposes only and is not necessarily indicative of the combined results of operations that would have been realized had the Transactions occurred as of the date indicated, nor is it meant to be indicative of any anticipated combined future results of operations of WillScot Mobile Mini. In addition, the accompanying unaudited pro forma condensed combined statement of operations does not include any expected cost savings or restructuring actions which may be achievable, or which may occur in the future. The historical combined financial information has been adjusted in the accompanying unaudited pro forma condensed combined financial statement to depict the income statement effects of the Transactions as though they occurred on January 1, 2020.
The Merger was 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 information. Under ASC 805, transaction costs are not included as a component of consideration transferred and are expensed as incurred. Under ASC 805, WillScot Mobile Mini 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. Such fair values are based on available information and certain assumptions that we believe are reasonable. The assignment of purchase price to assets acquired and liabilities assumed is subject to completion of the final analysis of the fair value of the rental equipment, intangible assets, and related deferred tax liabilities of Mobile Mini as of the date of the Merger, which will be finalized within the allowable one-year measurement period. Accordingly, the depreciation, amortization, and income tax benefit recorded in the unaudited pro forma condensed combined statement of operations are preliminary and final amounts may differ.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
(in thousands, except share and per share data)

NOTE 1 - Mobile Mini Merger
On July 1, 2020, Mobile Mini became a wholly-owned subsidiary of WillScot. Each share of Mobile Mini Common Stock issued and outstanding immediately prior to the Merger (other than shares held by Mobile Mini as treasury shares or owned by a subsidiary of Mobile Mini), was converted into the right to receive 2.405 shares of WillScot Class A Common Stock and cash in lieu of any fractional shares. Immediately following the Merger, WillScot changed its name to “WillScot Mobile Mini Holdings Corp.” and filed the A&R Charter, which reclassified all outstanding shares of WillScot Class A Common Stock and converted such shares into shares of WillScot Mobile Mini Common Stock.
Upon completion of the Merger, each outstanding and unexercised option to purchase shares of Mobile Mini Common Stock was assumed by WillScot Mobile Mini and converted to an option to purchase shares of WillScot Mobile Mini Common Stock using a conversion ratio of 2.405.
On July 1, 2020, WSHC, WSII, and certain of its subsidiaries, entered into a new asset-based credit agreement that provides for revolving credit facilities in the aggregate principal amount of up to $2.4 billion, consisting of: (i) a $2.0 billion US Facility and (ii) a $400 million Multicurrency Facility. On July 1, 2020, approximately $1.47 billion of proceeds from the 2020 ABL Facility were used to repay the WillScot ABL Facility and the Mobile Mini ABL Facility, as well as, to pay fees, costs, and expenses incurred in connection with the Merger and the related debt financing transactions.
On June 15, 2020 the Company completed a private offering of $650 million 2025 Secured Notes. The offering proceeds from the 2025 Secured Notes were used to redeem all 2022 Secured Notes, redeem the Mobile Mini 2024 Notes, and pay certain fees, costs, and expenses related to the Merger and the related financing transactions.
On June 30, 2020, Sapphire Holding exchanged each of its shares of common stock of WSHC for 1.3261 shares of WillScot Class A Common Stock. All issued and outstanding shares of WillScot's Class B Common Stock, par value $0.0001 per share, were automatically canceled for no consideration and the existing exchange agreement was automatically terminated. As a result of the Sapphire Exchange, Sapphire Holding became a wholly-owned subsidiary of WillScot. Prior to the Sapphire Exchange, Sapphire Holding’s ownership of WSHC was recorded as a non-controlling interest in the Company’s consolidated financial statements.
The unaudited pro forma condensed combined statement of operations was prepared to depict the income statement effects of the application of the acquisition method of accounting under the provisions of ASC 805 and was based on the historical financial information of WillScot Mobile Mini and Mobile Mini as adjusted to give effect to the Merger as if it had occurred on January 1, 2020. The purchase price consideration utilized for the pro forma condensed combined statement of operations measures consideration using the July 1, 2020 stock price of the Company and is consistent with the calculation included in the 2020 10K. Under the acquisition method of accounting, the total estimated purchase price of an acquisition is assigned to the net tangible and intangible assets to be acquired based on their estimated fair values as of the date of the acquisition. Such fair values are based on available information and certain assumptions that we believe are reasonable. The assignment of purchase price to assets acquired and liabilities assumed is subject to completion of the final analysis of the fair value of the rental equipment, intangible assets, and related deferred tax liabilities of Mobile Mini as of the date of the Merger, which will be finalized within the allowable one-year measurement period. Accordingly, the depreciation, amortization, and income tax benefit recorded in the unaudited pro forma condensed combined statement of operations are preliminary and final amounts may differ.

NOTE 2 - Accounting Policies and Reclassifications
During the preparation of the unaudited pro forma condensed combined statement of operations, the Company made an assessment as to any material differences between accounting policies of the two companies. The unaudited pro forma condensed combined statement of operations does not present any material differences in accounting policies between the two companies based on this assessment.
Financial information presented in the “Historical Mobile Mini” column in the unaudited pro forma condensed combined statement of operations has been reclassified to conform to the historical presentation of WillScot as noted below. This information represents the results of operations of Mobile Mini for the six months ended June 30, 2020, the period before the Merger. Results of operations for the period after the Merger are included in the “WillScot Mobile Mini Holdings Corp.” column in the unaudited pro forma condensed combined statement of operations.
