NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(1) Mobile Mini, Organization and Description of Business

Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage and specialty containment solutions. In these notes, the terms “Mobile Mini” and the “Company” refer to Mobile Mini, Inc. In December 2014, the Company acquired Gulf Tanks Holdings, Inc. (“GTH”), the parent company of Houston, Texas-based Evergreen Tank Solutions (“ETS”). The transaction, referred to as the “ETS Acquisition,” closed on December 10, 2014. On April 16, 2015, the Company entered into a definitive agreement to sell its wood mobile offices within its North American portable storage segment for a cash price of $92.0 million, less associated assumed liabilities of approximately $6.8 million. Cash received is net of transaction costs, as well as escrow amounts and certain other items to be settled over the next eighteen months. The transaction closed on May 15, 2015, resulting in the divestiture of the Company’s approximately 9,400 wood mobile units on that date.

At September 30, 2015, Mobile Mini has a fleet of portable storage units operating throughout the U.S., Canada and the U.K. The Company has a diversified customer base for its portable storage products, including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. These customers use the products for a wide variety of applications, including the storage of retail and manufacturing inventory, construction materials and equipment, and documents and records. The ETS Acquisition resulted in the addition of a fleet of specialty containment products, including liquid and solid containment units rented primarily to chemical, refinery, oil and natural gas drilling, mining and environmental service customers. The operating results of ETS are included in the three- and nine-month periods ended September 30, 2015.

Basis of Presentation and Consolidation

The consolidated financial statements include the accounts of Mobile Mini and its wholly owned subsidiaries. The Company does not have any subsidiaries in which it does not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management of Mobile Mini, Inc., all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows for all periods presented have been made. The results of operations for the three and nine months ended September 30, 2015 and 2014 are not necessarily indicative of the results to be expected for the full year.

These condensed consolidated financial statements should be read in conjunction with the Company’s December 31, 2014 audited consolidated financial statements and accompanying notes thereto, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 27, 2015.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. The most significant estimates and assumptions included within the financial statements are the allowance for doubtful accounts, the recoverability of goodwill, intangibles and other long-lived assets, accruals related to commitments and contingencies, and the estimated useful lives and residual values on the rental fleet, property, plant and equipment, and intangible assets.

Reclassifications

Certain amounts in the consolidated statements of operations for the three months ended March 31, 2015, which is included in the year-to-date period ended September 30, 2015, have been reclassified to conform to the current period presentation. The reclassifications have no effect on total revenues, loss from operations, net loss or net loss per common share. For the previously reported three-month period ended March 31, 2015, the reclassifications resulted in $2.1 million and $1.2 million increases to rental revenues and sales revenues, respectively, with an offsetting decrease to other revenue. For the same period, cost of sales increased $0.9 million, and rental, selling and general expenses decreased by the same amount. These reclassifications are related to the specialty containment business acquired in December 2014; accordingly, there are no corresponding prior period reclassifications.

The revenues reclassified to rental revenues from other revenues consist of ancillary services such as equipment cleaning fees and equipment installation. The items reclassified from other revenues to sales include sales of certain ancillary products. Costs associated with these sales have also been reclassified to cost of sales from rental, selling and general expenses. The Company believes the current presentation better reflects the nature of the underlying financial statement items.

(2) Recent Accounting Pronouncements

Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance on reporting discontinued operations and disclosures of disposals of components of an entity. The new guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance is effective for fiscal years beginning after December 15, 2014. The Company has applied this guidance prospectively to transactions occurring after December 31, 2014.

Revenue from Contracts with Customers. In May 2014, FASB issued the accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services. The standard is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for the annual and interim periods beginning after December 15, 2016, but not prior to that time. The revenue recognition standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the impact, if any, of the adoption of the standard to its financial statements and related disclosures. The Company has not yet selected a transition method nor determined the effect of the standard on its ongoing financial reporting.

Simplifying the Presentation of Debt Issuance Costs. In April 2015, FASB issued accounting guidance on the presentation of debt issuance costs in the balance sheet. This standard requires that certain debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. The Company will apply this guidance prospectively beginning in the fiscal year ended December 31, 2016. The application of this guidance will result in a reclassification of certain debt financing costs from other assets to a reduction of the specific debt liability, and will not affect the Company’s statement of operations or cash flow. As of September 30, 2015, the Company’s debt financing costs, net of accumulated amortization was $6.4 million.

Simplifying the Measurement of Inventory. In July 2015, FASB issued accounting guidance changing the measurement of inventory from lower of cost or market to lower of cost and net realizable value. The standard eliminates the requirement to consider replacement cost or net realizable value less a normal profit margin. The Company will apply this guidance prospectively beginning in the fiscal year ended December 31, 2017 and does not expect this standard to have a material effect on its financial statements and related disclosures.

(3) Fair Value Measurements

The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company utilizes the suggested accounting guidance for the three levels of inputs that may be used to measure fair value:     

Level 1 —	Observable inputs such as quoted prices in active markets for identical assets or liabilities;
Level 2 —	Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and
Level 3 —	Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.

At September 30, 2015 and December 31, 2014, the Company did not have any financial instruments required to be recorded at fair value on a recurring basis.

The carrying amounts of cash, receivables, accounts payable and accrued liabilities approximate fair values based on their short-term nature. The fair values of the Company’s revolving credit facility and capital leases are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company’s revolving credit facility debt and capital leases at September 30, 2015 and December 31, 2014 approximated their respective book values and are considered Level 2 in the fair value hierarchy.

MOBILE MINI, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited) - Continued

The fair value of the Company’s $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the “Senior Notes”) is based on their latest sales price at the end of each period obtained from a third-party institution which is considered a Level 2 input in the fair value hierarchy, as there is not an active market for these notes.

The carrying value and the fair value of the Company’s Senior Notes are as follows:

	September 30, 2015		December 31, 2014
	(In thousands)
Carrying value	$	200,000	$	200,000
Fair value		210,250		206,000

(4) Earnings (Loss) Per Share

Basic earnings (loss) per share (“EPS”) is calculated by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated under the treasury stock method. Potential common shares included nonvested share-awards, which are subject to risk of forfeiture, and incremental shares of common stock issuable upon the exercise of stock options.

The following table is a reconciliation of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS for the three and nine months ended September 30:

There were approximately 0.6 million of common stock equivalents that would have been included in the diluted EPS denominator for the nine month period ended September 30, 2015 had there not been a net loss. These common stock equivalents were excluded because their inclusion would reduce the net loss per share. In addition, the following table represents the number of stock options and nonvested share-awards that were issued or outstanding but excluded in calculating diluted EPS because their effect would have been anti-dilutive for the periods ended September 30:

(5) Impairment and Divestiture of North American Wood Mobile Offices

Mobile Mini’s business strategy is to invest in high return, low maintenance, long-lived assets. Wood mobile offices require more maintenance and upkeep than Mobile Mini’s steel containers and ground level offices, resulting in lower margins as compared to other portable storage products, as well as the newly-acquired specialty containment products. During March 2015, the Company entered into discussions regarding the possible sale of Mobile Mini’s wood mobile offices within its North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value.

Mobile Mini reviews long-lived assets such as rental fleet, property, plant and equipment, and intangibles, for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may be impaired. Based upon the events described above, the Company conducted a review for impairment for these particular long-lived assets as of March 31, 2015. The review included assumptions of cash flows considering the likelihood of possible outcomes that existed as of the date of the review, including assigning probabilities to these outcomes. Management estimated fair market value for the wood mobile offices based upon purchase price discussions. Based on this review, management determined that the assets were impaired as of March 31, 2015 and an impairment loss was recognized.

On April 16, 2015 the Company entered into a definitive agreement to sell its wood mobile offices within its North American portable storage segment for a cash price of $92.0 million, less associated deferred revenue and customer deposits of $6.8 million. The net assets were reclassified to held for sale as of that date. The transaction closed on May 15, 2015 and the Company recorded a net loss on the sale.

For the nine months ended September 30, 2015, the following amounts were recorded for the impairment and divestiture of the wood mobile office fleet.

	(In thousands)
Estimated fair market value	$	92,000
Net book value:
Wood mobile offices in rental fleet		155,429
Ancillary items in property, plant and equipment		1,201
Impairment loss	$	(64,630	)
Sale price	$	92,000
Book value of divested assets after impairment		92,000
Selling expenses		1,498
Net loss on sale of wood mobile offices	$	(1,498	)

The Company and the purchaser entered into a transition services agreement whereby the Company agreed to provide direct services such as transportation and maintenance for the wood mobile offices on behalf of the purchaser, as well as house units on the Company’s leased properties and provide certain administrative services such as billing and cash collection. The revenue related to this agreement is included in other revenue, and the expenses for providing these services are included in rental, selling and general expenses. Services provided are expected to decrease over the next three months.

(6) Acquisitions

In the nine months ended September 30, 2015, Mobile Mini completed two acquisitions of portable storage businesses. These acquisitions expanded the Company’s existing operations in the Glasgow, Scotland market and further strengthened the Company’s positions in Knoxville and Chattanooga, Tennessee. The accompanying consolidated financial statements include the operations of the acquired businesses from the date of acquisition. The aggregate purchase price for the assets and liabilities acquired were recorded based on their estimated fair values at the date of the acquisitions. The Company has not disclosed the pro-forma impact of the acquisitions on operations as it was immaterial to the Company’s financial position in the aggregate.

The components of the purchase price and net assets acquired during the nine months ended September 30, 2015 are as follows (in thousands):

Net Assets Acquired:
Rental fleet	$	12,252
Property, plant and equipment		157
Intangible assets:
Customer relationships		759
Non-compete agreements		74
Goodwill		5,343
Other assets		318
Liabilities		(281	)
Total purchase price	$	18,622

(7) Inventories

Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out (“FIFO”) method) or market. Market is the lower of replacement cost or net realizable value.

Raw materials principally consist of raw steel, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes, and to a lesser extent, parts used for internal maintenance, and ancillary items held for sale in the Company’s specialty containment segment. Work-in-process primarily represents partially assembled units pre-sold or for use as fleet. Finished portable storage units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet.

Inventories at September 30, 2015 and December 31, 2014 consisted of the following:

	September 30, 2015		December 31, 2014
	(In thousands)
Raw materials and supplies	$	14,404	$	14,241
Work-in-process		207		201
Finished portable storage units		2,951		2,294
Inventories	$	17,562	$	16,736

(8) Rental Fleet

Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred.

Management periodically reviews depreciable lives and residual values against various factors, including the results of its lenders’ independent appraisal of rental fleet, practices of competitors in comparable industries, profit margins achieved on sales of depreciated units and rental rates obtained on older units. See Note 5 for information regarding the impairment and divestiture of wood mobile offices during 2015.

Appraisals on the Company’s portable storage fleet are conducted on a regular basis by an independent appraiser selected by its lenders. Based on the values assigned in the most recent appraisal as of September 30, 2014, the portable storage rental fleet orderly liquidation value was approximately $1.0 billion as of September 30, 2015. In addition, an appraisal of the specialty containment fleet was conducted as of December 2014 in conjunction with the ETS Acquisition. Based upon the values assigned in this appraisal, the specialty containment rental fleet orderly liquidation value was approximately $94 million as of September 30, 2015. These appraisals were conducted by AccuVal Associates, Incorporated and are used to calculate the Company’s available borrowings under its Credit Agreement, as described in Note 11.

(1) Specialty containment fleet has been assigned zero residual value.

(9) Property, Plant and Equipment

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is provided using the straight-line method over the assets’ estimated useful lives. The Company’s depreciation expense related to property, plant and equipment for the nine months ended September 30, 2015 and 2014 was $14.8 million and $10.9 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the Consolidated Statements of Operations. See Note 5 for information regarding the impairment and divestiture of ancillary equipment related to wood mobile offices during 2015.

(1) Improvements made to leased properties are depreciated over the lesser of the estimated remaining life or the remaining term of the respective lease.

(10) Goodwill and Intangibles

For acquired businesses, the Company records assets acquired and liabilities assumed at their estimated fair values on the respective acquisition dates. Based on these values, the excess purchase prices over the fair value of the net assets acquired is recorded as goodwill. Estimated fair values of acquired assets is provisional and could change as additional information is received. During the nine months ended September 30, 2015, primarily due to further analysis of the assets acquired in the ETS acquisition, the associated goodwill was adjusted upward by $0.9 million.

The following table shows the activity and balances related to goodwill from January 1, 2015 to September 30, 2015:

	(In thousands)
Balance at January 1, 2015	$	705,608
Acquisition		5,343
Foreign currency		(2,220	)
Adjustments		893
Balance at September 30, 2015	$	709,624

Intangible assets are amortized over the estimated useful life of the asset utilizing a method which reflects the estimated pattern in which the economic benefits will be consumed. Customer relationships and certain trade names and trademarks, are amortized using an accelerated method while other intangibles are amortized using the straight-line method.

The following table reflects balances related to intangible assets for the periods presented:

(11) Lines of Credit

The Company has a $1.0 billion ABL Credit Agreement with Deutsche Bank AG New York Branch and other lenders party thereto (the “Credit Agreement”). The Credit Agreement provides for a five-year, revolving credit facility and all amounts outstanding under the Credit Agreement are due on February 22, 2017. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of its assets.

Amounts borrowed under the Credit Agreement and repaid or prepaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement bear interest at the Company’s option at either: (i) LIBOR plus a defined margin, or (ii) the Agent bank’s prime rate plus a margin. The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans at each measurement date. As of September 30, 2015, the applicable margins are 2.0% for LIBOR loans and 1.0% for base rate loans.

Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of the Company’s eligible accounts receivable, eligible container fleet (including containers held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the net orderly liquidation value, as defined in the Credit Agreement, is included in the borrowing base to determine how much the Company may borrow under the Credit Agreement.

The Credit Agreement provides for U.K. borrowings, which are, at the Company’s option, denominated in either Pounds Sterling or Euros, by its U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by its Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, by the Company based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary.

The Credit Agreement also contains customary negative covenants, including covenants that restrict the Company’s ability to, among other things: (i) allow certain liens to attach to the Company or its subsidiary assets; (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, prepay certain indebtedness or make acquisitions or other investments subject to Payment Conditions (as defined in the Credit Agreement); and (iii) incur additional indebtedness or engage in certain other types of financing transactions. Payment Conditions allow restricted payments and acquisitions to occur without financial covenants as long as the Company has $250.0 million of pro forma excess borrowing availability under the Credit Agreement. The Company must also comply with specified financial maintenance covenants and affirmative covenants only if the Company falls below $100.0 million of borrowing availability levels with set permitted values for the Debt Ratio and Fixed Charge Coverage Ratio (as defined in the Credit Agreement). The Company was in compliance with the terms of the Credit Agreement as of September 30, 2015, and was above the minimum borrowing availability threshold and therefore not subject to any financial maintenance covenants.

(12) Income Taxes

The Company files U.S. Federal tax returns, U.S. state tax returns and foreign tax returns. The Company has identified its U.S. Federal tax return as its “major” tax jurisdiction. For the U.S. Federal return, its tax years for 2012, 2013 and 2014 are subject to tax examination by the U.S. Internal Revenue Service through September 15, 2016, 2017 and 2018, respectively. The Company does not anticipate that the total amount of unrecognized tax benefit related to any particular tax position will change significantly within the next 12 months.

The Company uses a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.

MOBILE MINI, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited) - Continued

The Company’s policy for recording interest and penalties associated with audits is to record such items as a component of income before taxes. Penalties and associated interest costs, if any, are recorded in rental, selling and general expenses in its Condensed Consolidated Statements of Operations.

(13) Share-based Compensation

The Company has historically awarded stock options and nonvested share-awards for employees and non-employee directors as a means of attracting and retaining quality personnel and to align employee performance with stockholder value. Stock option plans are approved by the Company’s stockholders and administered by the compensation committee of the board of directors (“Board”). The current plan allows for a variety of equity programs designed to provide flexibility in implementing equity and cash awards, including incentive stock options, nonqualified stock options, nonvested share-awards, restricted stock units, stock appreciation rights, performance stock, performance units and other share-based awards. Participants may be granted any one of the equity awards or any combination. The Company does not award stock options with an exercise price below the market price of the underlying securities on the date of award. As of September 30, 2015, 2.5 million shares remain available for future grants. Generally stock options have contractual terms of ten years.

The following table summarizes the Company’s share-based compensation for the three and nine months ended September 30:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2015		2014		2015		2014
	(In thousands)				(In thousands)
Share-based compensation expense included in:
Rental, selling and general expenses	$	3,418	$	4,156	$	9,283	$	11,297
Restructuring expenses		678		276		1,550		276
Total share-based compensation	$	4,096	$	4,432	$	10,833	$	11,573

As of September 30, 2015, total unrecognized compensation cost related to stock option awards was approximately $6.0 million and the related weighted-average period over which it is expected to be recognized is approximately 1.1 years. As of September 30, 2015, the unrecognized compensation cost related to nonvested share-awards was approximately $6.5 million, which is expected to be recognized over a weighted-average period of approximately 2.1 years.

Stock options. The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes option pricing model which requires the input of assumptions. Management estimates the risk-free interest rate based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options, volatility and dividend rates are estimated based on the Company’s historical data. The following are the key assumptions used for options granted during the nine-month periods ended September 30:

	2015	2014
Risk-free interest rate	1.3% - 1.7%	1.5% - 1.7%
Expected life of the options (years)	5	5
Expected stock price volatility	35.3% - 35.7%	36.6% - 38.4%
Expected dividend rate	1.8% - 2.0%	1.5% - 1.8%

(14) Restructuring Costs

The Company has undergone restructuring actions to align its business operations. These activities materially change the scope of the business or the manner in which the business is conducted. In 2015, restructuring costs relate primarily to activities associated with the integration of ETS into the existing Mobile Mini infrastructure, including the Company’s shift from managing its operations on a product-oriented basis to a geographic, customer-focused organization. To support this shift, the Company also aligned sales leadership with operational leadership. The 2014 restructuring costs primarily relate to the closure of the Company’s Belfast, North Ireland location as well as the transition of key leadership positions. The accrued restructuring obligations as of September 30, 2015 were related to the Company’s operations in North America.

The following table details accrued restructuring obligations (included in accrued liabilities in the Consolidated Balance Sheets) and related activity for the year ended December 31, 2014 and the nine-month period ended September 30, 2015.

	Severance and Benefits			Lease Abandonment Costs			Other Costs			Total
	(In thousands)
Accrued obligations as of January 1, 2014	$	613		$	1,063		$	—		$	1,676

Restructuring expenses	$	1,846	$	593		$	4,773	$	2,909

(15) Commitments and Contingencies

Mobile Mini is a party to various claims and litigation in the normal course of business. Management’s current estimated range of liability related to various claims and pending litigation is based on claims for which management can determine that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Because of the uncertainties related to both the probability of incurred and possible range of loss on pending claims and litigation, management must use considerable judgment in making a reasonable determination of the liability that could result from an unfavorable outcome. As additional information becomes available estimates will be revised as appropriate. Management does not anticipate the resolution of such matters known at this time will have a material adverse effect on the Company’s business or consolidated financial position.

(16) Stockholders’ Equity

Dividends

On January 21, 2015, April 29, 2015, and July 21, 2015 the Board authorized and declared a cash dividend to all the Company’s common stockholders of $0.187 per share of common stock. These dividends were paid on March 19, 2015, June 3, 2015, and September 2, 2015 respectively, to all stockholders of record as of the close of business on March 5, 2015, May 20, 2015 and August 19, 2015. Each future quarterly dividend payment is subject to review and approval by the Board. The Company’s Credit Agreement contains restrictions on the declaration and payment of dividends.

Treasury stock

On November 6, 2013, the Board approved a share repurchase program authorizing up to $125.0 million of the Company’s outstanding shares of common stock to be repurchased, and on April 17, 2015 authorized an additional $50.0 million for the repurchase program, for a total of $175.0 million. The shares may be repurchased from time to time in the open market or in privately negotiated transactions. The share repurchases are subject to prevailing market conditions and other considerations. The share repurchase program does not have an expiration date and may be suspended or terminated at any time by the Board. All shares repurchased are held in treasury.

During the nine months ended September 30, 2015, the Company purchased approximately 1.5 million shares of its common stock at a cost of $55.4 million under the authorized share repurchase program, and approximately $94.7 million is available for repurchase as of September 30, 2015. In addition, the Company withheld approximately 11,000 shares of stock from employees, for an approximate value of $0.4 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

During the nine months ended September 30, 2014, the Company purchased approximately 0.6 million shares of its common stock at a cost of $25.0 million under the authorized share repurchase program.

(17) Segment Reporting

Prior to the ETS Acquisition, the Company’s operations were comprised of two reportable segments: North America and the U.K., both of which offer portable storage solutions. Discrete financial data on each of the Company’s products is not available and it would be impractical to collect and maintain financial data in such a manner. As a result of the ETS Acquisition, the Company established a new specialty containment reporting segment. Operations related to ETS are included in Mobile Mini’s consolidated results for the nine months ended September 30, 2015. The results for each segment are reviewed discretely by senior management.

All of the Company’s locations operate in their local currency and, although the Company is exposed to foreign exchange rate fluctuation in foreign markets where the Company rents and sells its products, the Company does not believe such exposure will have a significant impact on its results of operations.

The following tables set forth certain information regarding each of the Company’s segments for the three-month periods ended September 30, 2015 and 2014.

(19) Condensed Consolidating Financial Information

The following tables reflect the condensed consolidating financial information of the Company’s subsidiary guarantors of the Senior Notes and its non-guarantor subsidiaries. Separate financial statements of the subsidiary guarantors are not presented because the guarantee by each 100% owned subsidiary guarantor is full and unconditional, joint and several, subject to customary exceptions, and management has determined that such information is not material to investors.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read together with our December 31, 2014 consolidated financial statements and the accompanying notes thereto which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the Securities and Exchange Commission (“SEC”). This discussion contains forward-looking statements. Forward-looking statements are based on current expectations and assumptions that involve risks and uncertainties. Our actual results may differ materially from those anticipated in our forward-looking statements. The tables and information in this “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” section were derived from exact numbers and may have immaterial rounding differences.

Overview

Executive Summary

We are the world’s leading provider of portable storage solutions, maintaining a strong leadership position in virtually all markets served. Our mission is to be the leader in portable storage solutions to customers throughout North America and the U.K. and specialty containment solutions in the U.S. We are committed to providing our customers with superior service and access to a high-quality and diverse fleet. In managing our business, we focus on renting rather than selling our units, with rental revenues representing approximately 92.9% of our total revenues for the nine months ended September 30, 2015. We believe this strategy provides us with predictable, recurring revenue. Additionally, our assets have long useful lives, low maintenance costs and generally maintain their value throughout their useful lives. We also sell new and used units and provide delivery, installation and other ancillary products and value-added services.

On December 10, 2014, we completed the acquisition (the “ETS Acquisition”) of Evergreen Tank Solutions (“ETS”). ETS is the third largest provider of specialty containment solutions in the U.S. and the leading provider in the Gulf Coast region. ETS operates as a separate subsidiary under the ETS name (as does its own subsidiary, Water Movers, Inc.), and its operations are included in our results of operations for the nine months ended September 30, 2015.

On May 15, 2015, we completed the divestiture of our North American wood mobile office fleet. Our business strategy is to invest in high return, low maintenance, long-lived assets. Wood mobile offices require more maintenance and upkeep than Mobile Mini’s steel containers and steel ground level offices, resulting in lower margins as compared to our other portable storage products, as well as the newly-acquired specialty containment products. During March 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American Portable Storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value and we conducted a review for impairment for these long-lived assets as of March 31, 2015. Based on this review, an impairment loss was recorded in the quarter ended March 31, 2015. Upon completion of the sale in May 2015, a loss on sale was recorded. The total impairment and loss on the divestiture of the wood mobile offices was $66.1 million during the nine-month period ended September 30, 2015. See additional discussion regarding the impairment and the divestiture of the wood mobile offices in Note 5 to the accompanying condensed consolidated financial statements.

As of September 30, 2015, our network includes 133 portable storage locations, 19 specialty containment locations and 6 combined locations. Our portable storage fleet consists of approximately 209,500 units and our specialty containment business has a fleet of approximately 11,400 units.

Business Environment and Outlook. Excluding the divested wood mobile business, approximately 61% of our estimated combined rental revenue (including estimated ETS rental revenue prior to the time of acquisition) during the twelve-month period ended September 30, 2015 was derived from our North American portable storage business, 18% was derived from our U.K. portable storage business and 21% was derived from our specialty containment business. Our business is subject to the general health of the economy and we utilize a variety of general economic indicators to assess market trends and determine the direction of our business.

Based on our assessment, we expect that the majority of our end markets will continue to drive demand for our products. In particular, construction, which represents approximately 41% of our consolidated rental revenue, is forecasted by third parties for continued growth for the next several years. While only 3% of our consolidated rental revenue is generated by oil and gas customers, the oil and gas industry is forecasted by third parties to continue to remain challenged in the near term.

Accounting and Operating Overview

Our principal operating revenues and expenses are:

Revenues:

• Rental revenues include all rent and ancillary revenues we receive for our rental fleet.

• Sales revenues consist primarily of sales of new and used portable storage products, used specialty containment fleet, and to a lesser extent, parts and supplies sold to specialty containment customers.

28

Costs and expenses:

• Rental, selling and general expenses include, among other expenses, payroll and payroll-related costs including share-based compensation and commissions for our sales team, fleet transportation and fuel costs, repair and maintenance costs for our rental fleet and transportation equipment, real estate lease expense, insurance costs, and general corporate expenses.

• Cost of sales is the net book value of the units that were sold during the reported period and includes both our cost to buy, transport, remanufacture and modify used containers and our cost to manufacture portable storage units and other structures. To a lesser extent, cost of sales includes parts and supplies sold to specialty containment customers.

• Depreciation and amortization includes depreciation on our rental fleet, our property, plant and equipment, and amortization of definite-lived intangible assets.

Our principal assets consist of our rental fleet, which is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred.

The table below outlines the composition of our portable storage rental fleet at September 30, 2015:

	Rental Fleet			Number of Units		Percentage of Units
	(In thousands)
Steel storage containers	$	622,312			177,727		85	%

We are a capital-intensive business. Therefore in addition to focusing on measurements calculated in accordance with generally accepted accounting principles in the U.S. (“GAAP”), we focus on EBITDA, adjusted EBITDA, and free cash flow to measure our operating results. EBITDA, adjusted EBITDA and the resultant margins, as well as free cash flow are non-GAAP financial measures. As such, we include in this Quarterly Report on Form 10-Q reconciliations to their most directly comparable GAAP financial measures. These reconciliations and a description of the limitations of these measures are included below in this report.

Non-GAAP Data and Reconciliations

EBITDA and Adjusted EBITDA. EBITDA eliminates the effect of financing transactions that we enter into and is defined as net income before discontinued operation, net of tax (if applicable), interest expense, income taxes, depreciation and amortization, and debt restructuring or extinguishment expense (if applicable), including any write-off of deferred financing costs. Adjusted EBITDA further excludes certain non-cash expenses, such as share-based compensation, as well as transactions that management believes are not indicative of our business. Because EBITDA and adjusted EBITDA, as defined, exclude some but not all items that affect our cash flow from operating activities, they may not be comparable to similarly titled performance measures presented by other companies.

29

We present EBITDA and adjusted EBITDA because we believe they provide an overall evaluation of our financial condition and that they provide useful information regarding our ability to meet our future debt payment requirements, capital expenditures and working capital requirements. EBITDA and adjusted EBITDA have certain limitations as analytical tools and should not be used as substitutes for net income, cash flows from operations, or other consolidated income or cash flow data prepared in accordance with GAAP.

Reconciliation of net income (loss) to EBITDA and adjusted EBITDA is as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,

(1) Share-based compensation represents non-cash compensation expense associated with the granting of equity instruments. The reconciliation of net cash provided by operating activities to EBITDA includes share-based compensation recognized within restructuring expense. For more information, see Note 13 to the accompanying condensed consolidated financial statements.

30

(2) The Company has undergone restructuring actions to align its business operations. These activities materially change the scope of the business or the manner in which the business is conducted. For more information, see Note 14 to the accompanying condensed consolidated financial statements.

(3) Incremental costs associated with acquisitions.

(4) In 2015, these costs represent asset impairment charge and loss on the wood mobile office divestiture, net. For more information about the wood mobile office divestiture, see Note 5 to the accompanying condensed consolidated financial statements. In 2014, these costs represent the additional loss upon completion of sale (offset by gains upon completion of sale) of assets that were written down to fair value in the second quarter of 2013.

(5) Transition services revenue and operating expenses associated with the provision of transition services related to the wood mobile divestiture, including expenses related to wood mobile offices on our leased properties.

(6) Revenue associated with a sales tax refund recorded in the first quarter.

(7) Expenses related to the proposed settlement of an outstanding unclaimed property liability with the state of Delaware.

(8) Revenue discussed above associated with the sales tax refund and the transition services were excluded in the calculation of the adjusted EBITDA margin.

Free Cash Flow. Free cash flow is defined as net cash provided by operating activities, minus or plus, net cash used in or provided by investing activities, excluding acquisitions and certain transactions, including the cash received related to the divestiture of the wood mobile office fleet. Free cash flow is a non-GAAP financial measure and is not intended to replace net cash provided by operating activities, the most directly comparable financial measure prepared in accordance with GAAP. We present free cash flow because we believe it provides useful information regarding our liquidity and ability to meet our short-term obligations. In particular, free cash flow indicates the amount of cash available after capital expenditures for, among other things, investments in our existing business, debt service obligations, payment of authorized quarterly dividends, repurchase of our common stock and strategic small acquisitions.

Reconciliation of net cash provided by operating activities to free cash flow is as follows:

Revenues. The following table depicts revenue by type of business for the three-month periods ended September 30:

	Three Months Ended September 30,
	Portable Storage									Specialty Containment
	2015		2014		Increase (Decrease) 2015 versus 2014					2015
	(In thousands, except percentages)
Revenues:
Rental	$	98,855	$	104,798	$	(5,943	)	(5.7	)%	$	25,958
Sales		4,830		7,913		(3,083	)	(39.0	)		1,764
Other		1,909		611		1,298		212.4			27
Total revenues	$	105,594	$	113,322	$	(7,728	)	(6.8	)	$	27,749

Total revenues for the quarter ended September 30, 2015 increased $20.0 million, or 17.7%, to $133.3 million, compared to $113.3 million for the same period in 2014. The increase is due to $27.7 million related to the acquired specialty containment business, partially offset by a $7.7 million decrease in portable storage revenues resulting from the divestiture of the wood mobile office business, which contributed $12.0 million of total revenue in the prior-year quarter. Rental revenues as a percentage of total revenues was 93.6%, compared to 92.5% in the prior-year quarter. Rental revenues for the quarter ended September 30, 2015 increased $20.0 million, or 19.1%, to $124.8 million, compared to $104.8 million for the same period in 2014. Specialty containment rental revenue of $26.0 million was partially offset by a decrease of $5.9 million in portable storage rental revenues, from $104.8 million to $98.9 million.

32

The decreased rental revenues within the portable storage business is a result of the second quarter 2015 divestiture of wood mobile offices discussed previously. In the third quarter of 2015, the Company did not have any revenue related to the divested assets, as compared to $11.4 million of associated rental revenue in the third quarter of 2014.

Rental revenue related to the remaining portable storage business increased approximately $5.4 million, or 5.8%, driven by a 3.7% increase in rental rates as well as a 3.9% increase in units on rent. These increases in revenue were partially offset by unfavorable currency translation rates in the current year, as compared to the prior year. Adjusted for the change in currency translation rates and excluding the divested assets, rental revenue increased approximately 7.7%. Excluding the divested wood mobile offices and adjusted for the unfavorable currency effect, yield (calculated as rental revenues divided by average units on rent) increased approximately 3.6% as compared to the prior-year quarter.

Portable storage sales revenue for the quarter ended September 30, 2015 decreased $3.1 million, or 39%, to $4.8 million, compared to $7.9 million in the same period in 2014. Revenue from specialty containment sales was $1.8 million for the quarter ended September 30, 2015. We focus on rental revenues; as such and in general, sales of units from our fleet occur due to a particular customer need, or due to having fleet in excess of demand at a particular location.

Costs and expenses. The following table depicts costs and expenses by type of business for the three-month periods ended September 30:

	Three Months Ended September 30,
	Portable Storage									Specialty Containment
	2015		2014		Increase (Decrease) 2015 versus 2014					2015
	(In thousands, except percentages)

Cost of sales		3,124		5,199		(2,075	)	(39.9	)		1,242
Restructuring expenses		248		593		(345	)	(58.2	)		1,598
Depreciation and amortization		8,404		9,470		(1,066	)	(11.3	)		6,594
Total costs and expenses	$	78,066	$	83,151	$	(5,085	)	(6.1	)	$	24,803

Rental, selling and general expenses for portable storage decreased $1.6 million, or 2.4%. As a percentage of total portable storage revenues, rental, selling and general expenses increased to 62.8% in the current quarter, from 59.9% in the three months ended September 30, 2014. The increase as a percentage of revenues was largely driven by $2.2 million of expense associated with the transition services agreement, $0.4 million of acquisition-related expenses and $0.2 million related to a proposed unclaimed property settlement. Excluding these items, which we do not consider to be indicative of our business, as well as the $1.2 million of transition services revenue; rental, selling and general expenses were 61.0% of total portable storage revenues.

The $2.8 million increase in expenses discussed above was more than offset by approximately $4.4 million of other net decreases, resulting in a $1.6 million total net decrease in rental, selling and general expense within the portable storage business. These decreases were driven by lower fleet freight and fuel, and repairs and maintenance resulting primarily from decreased activity related to the wood mobile office business. In addition, decreasing fuel prices and fleet positioning activity contributed to this decrease. Excluding expenses associated with the provision of transition services, repairs and maintenance on our portable storage rental fleet as a percentage of rental revenue was 5.3%, compared to 6.4% in the prior-year quarter.

The approximately $2.2 million in expenses incurred to provide transition services related to the divestiture of our wood mobile offices includes direct expenses to transport and maintain the assets on behalf of the purchaser, as well as expenses incurred related to wood mobile offices on our leased properties and certain administrative expenses such as billing and revenue collection.

Specialty containment rental, selling and general expense was $15.4 million for the quarter ended September 30, 2015, or 55.4% of total specialty containment revenues.

Cost of sales is the cost related to our sales revenue only. Within the portable storage business, cost of sales was $3.1 million and $5.2 million in the quarters ended September 30, 2015 and 2014, respectively. Portable storage sales revenue, less cost of sales (sales profit), was $1.7 million and $2.7 million for the three-month periods ended September 30, 2015 and 2014, respectively. Sales profit expressed as a percentage of sales revenue (sales profit margin) was 35.3% in the quarter ended September 30, 2015 and 34.3% in the prior-year quarter. Cost of sales related to our specialty containment products was $1.2 million in the quarter ended September 30, 2015. Specialty containment products sales profit and profit margin were $0.5 million and 29.6% in the quarter ended September 30, 2015.

33

In the third quarter of 2015, restructuring costs relate primarily to activities associated with the integration of ETS into the existing Mobile Mini infrastructure, including the Company’s shift from managing its operations on a product-oriented basis to a geographic, customer-focused organization. To support this shift, the Company aligned sales leadership with operational leadership. The 2014 restructuring costs primarily relate to the transition of key leadership positions.

We expect the restructuring costs associated with the projects noted above to continue throughout the remainder of 2015 and 2016. In addition, upon the completion of the wood mobile office divestiture, including transition services, we expect further restructuring costs as we consolidate yards and reduce yard space to reduce ongoing costs.

Depreciation and amortization expense increased $5.5 million for the three months ended September 30, 2015, as compared to the prior-year quarter. Increased depreciation of $6.6 million related to the specialty containment business was partially offset by a decrease of $1.1 million related to the portable storage business due to the divestiture of the wood mobile offices.

Adjusted EBITDA. Adjusted EBITDA increased $7.7 million, or 17.3%, to $52.1 million, compared to $44.4 million in the prior-year period. Adjusted EBITDA of $11.2 million related to our specialty containment business was partially offset by a decrease of $3.5 million related to our portable storage business. The reduction in portable storage adjusted EBITDA is primarily a result of the wood mobile office divestiture. Adjusted EBITDA margins were 39.5% and 39.2% for the quarters ended September 30, 2015 and 2014, respectively. Adjusted EBITDA margins for the quarter ended September 30, 2015 were 39.3% for our portable storage business and 40.4% for our specialty containment business.

Interest Expense. Interest expense increased $1.9 million, or 26.1%, to $9.0 million in the third quarter of 2015, compared to the same quarter in the prior year. In December 2014, we borrowed funds under our Credit Agreement to facilitate the ETS Acquisition. Our average debt outstanding in the quarter ended September 30, 2015 was $886.5 million, as compared to $517.0 million in the prior-year quarter. The weighted average interest rate on our debt was 3.7% and 4.9% for the three months ended September 30, 2015 and 2014, respectively, excluding the amortizations of debt issuance costs. Taking into account the amortization of debt issuance costs, the weighted average interest rate was 4.0% and 5.5% for the three month periods ended September 30, 2015 and 2014, respectively. The decrease in the average interest rate is primarily due to the increase of our lower rate line of credit, as a percentage of our overall debt.

Provision for income taxes. During the quarter ended September 30, 2015, we had a $7.5 million provision for income taxes, compared to $8.2 million in the prior-year quarter. Our effective income tax rate decreased slightly to 35.0% for three months ended September 30, 2015, compared to 35.7% for the prior-year period. The decrease in the tax rate is primarily due to the increase in profitability of our U.K. operations, which has a lower tax rate, as a percentage of our total pre-tax profit.

Net income. As a result of the income statement activity discussed above, we had net income of $14.0 million for the three months ended September 30, 2015, compared to net income of $14.8 million in the prior-year quarter.

Revenues. The following table depicts revenue by type of business for the nine-month periods ended September 30:

	Nine Months Ended September 30,
	Portable Storage									Specialty Containment
	2015		2014		Increase (Decrease) 2015 versus 2014					2015
	(In thousands, except percentages)

Total revenues	$	315,054	$	322,259	$	(7,205	)	(2.2	)	$	81,206

Total revenues for the nine months ended September 30, 2015 increased $74.0 million, or 23.0%, to $396.3 million, compared to $322.3 million for the same period in 2014. This increase is due to $81.2 million related to the acquired specialty containment business, partially offset by a $7.2 million decrease in portable storage revenues. The divested wood mobile office business contributed approximately $17.0 million of total revenue in the current-year period, as compared to $34.6 million in the prior-year period. Rental revenues as a percentage of total revenues was 92.9%, compared to 92.1% in the prior-year period. Rental revenues for the nine months ended September 30, 2015 increased $71.3 million, or 24.0%, to $368.2 million, compared to $296.9 million for the same period in 2014. Specialty containment rental revenue accounted for $75.3 million of this increase, while portable storage rental revenue decreased $4.0 million to $292.9 million, from $296.9 million in the prior-year period.

35

Revenues within the portable storage business were affected by the wood mobile office divestiture on May 15, 2015, as discussed earlier in this report. In the first nine months of 2015, the divested business contributed approximately $15.8 million of rental revenue, as compared to $32.5 million of rental revenue in the first nine months of 2014, a difference of $16.7 million.

The rental revenue related to the remaining portable storage business increased approximately $12.8 million, or 4.8%, driven by a 5.0% increase in rental rates. The increased rate was partially offset by unfavorable currency translation rates in the current year, as compared to the prior year. Adjusted for the change in currency translation rates and excluding the divested assets, rental revenue increased approximately 7.0%. Excluding the divested wood mobile offices and adjusted for the effect of unfavorable currency rates, yield increased approximately 5.4%, as compared to the prior-year period.

Revenue from the sales of portable storage and office units for the nine months ended September 30, 2015 decreased $6.9 million, or 28.9%, to $16.9 million, compared to $23.8 million in the same period in 2014. Revenue from specialty containment sales was $5.9 million for the nine months ended September 30, 2015. We focus on rental revenues; as such and in general, sales of units from our fleet occur due to a particular customer need, or due to having fleet in excess of demand at a particular location.

Costs and expenses. The following table depicts costs and expenses by type of business for the nine-month periods ended September 30:

Rental, selling and general expenses for portable storage decreased $3.9 million, or 1.9%, and as a percentage of total portable storage revenues increased slightly to 63.7% from 63.4% for the nine months ended September 30, 2015 and 2014, respectively. The increase as a percentage of revenues was largely driven by $3.9 million of expense associated with the transition services agreement, $2.3 million of acquisition-related expenses and $0.8 million related to a proposed unclaimed property settlement. Excluding these items, which we do not consider to be indicative of our business, as well as the $2.5 million of transition services revenue and $1.2 million of revenue associated with the receipt of a sales tax refund; rental, selling and general expenses were 62.2% of total portable storage revenues.

The $7.1 million increase in expenses discussed above was more than offset by approximately $11.0 million of other net decreases, resulting in a $3.9 million total net decrease in rental, selling and general expense within the portable storage business. These decreases were driven by lower fleet freight and fuel, and repairs and maintenance resulting primarily from decreased activity related to the wood mobile office business. In addition, decreasing fuel prices and fleet positioning activity contributed to this decrease. Excluding expense associated with providing transition services, repairs and maintenance on our portable storage rental fleet as a percentage of rental revenue was 5.0%, compared to 6.8% in the prior-year period.

The approximately $3.9 million in expenses incurred to provide transition services related to the divestiture of our wood mobile offices includes direct expenses to transport and maintain the assets on behalf of the purchaser, as well as expenses related to wood mobile offices on our leased properties, and certain administrative services such as billing and cash collection.

Specialty containment rental, selling and general expense was $47.3 million for the nine-month period ended September 30, 2015, or 58.2% of total specialty containment revenues.

Cost of sales is the cost related to our sales revenue only. Within the portable storage business, cost of sales was $11.0 million and $16.1 million in the nine months ended September 30, 2015 and 2014, respectively. Portable storage sales profit was $5.9 million and $7.6 million for the nine-month periods ended September 30, 2015 and 2014, respectively. Sales profit margin was 35.0% in the current-year period and 32.1% in the prior-year period. Cost of sales related to our specialty containment products was $3.9 million in the nine-month period ended September 30, 2015. Specialty containment product sales profit and profit margin were $2.0 million and 33.2%, respectively, for the nine-month period ended September 30, 2015.

36

In 2015, restructuring costs relate primarily to activities associated with the integration of ETS into the existing Mobile Mini infrastructure, including the Company’s shift from managing its operations on a product-oriented basis to a geographic, customer-focused organization. To support this shift, the Company aligned sales leadership with operational leadership. The 2014 restructuring costs primarily relate to the transition of key leadership positions, as well as the closure of our Belfast, North Ireland location.

As discussed previously in this report, during the nine months ended September 30, 2015, we recorded impairment charges and loss on divestiture of $66.1 million related to our wood mobile offices in our North American portable storage segment. See additional discussion regarding the impairment and divestiture of the wood mobile office assets in Note 5 to the accompanying condensed consolidated financial statements. Asset impairment charges, net of recoveries, were $0.6 million for the nine months ended September 30, 2014 and relate to gains and losses upon completion of the sale, or other disposal of assets impaired in a 2013 assessment of the rental fleet resulting in a non-cash impairment charge on long-lived assets.

Depreciation and amortization expense increased $17.2 million for the nine months ended September 30, 2015, as compared to the prior-year period. Increased depreciation of $19.0 million related to the specialty containment business was partially offset by a decrease of $1.9 million related to the portable storage business. Subsequent to the impairment of the wood mobile office business, no additional depreciation was recognized on these assets.

Adjusted EBITDA. Adjusted EBITDA increased $32.8 million, or 29.0%, to $145.9 million, compared to $113.1 million in the prior-year period. Of this increase, $2.4 million related to our portable storage business and $30.4 million related to our newly-acquired specialty containment business. Adjusted EBITDA margins were 37.2% and 35.1% for the nine months ended September 30, 2015 and 2014, respectively. Adjusted EBITDA margins for the nine-month period ended September 30, 2015 were 37.1% for our portable storage business and 37.5% for our specialty containment business.

Interest Expense. Interest expense increased $5.8 million, or 27.3%, to $27.0 million in 2015. In December 2014, we borrowed funds under our Credit Agreement to facilitate the ETS Acquisition. Our average debt outstanding in the nine-month period ended September 30, 2015 was $902.4 million, as compared to $513.2 million in the prior-year period. The weighted average interest rate on our debt was 3.6% and 4.9% for the nine months ended September 30, 2015 and 2014, respectively, excluding the amortizations of debt issuance costs. Taking into account the amortization of debt issuance costs, the weighted average interest rate was 4.0% and 5.5% for the nine-month periods ended September 30, 2015 and 2014, respectively. The decrease in the average interest rate is primarily due to the increase of our lower rate line of credit, as a percentage of our overall debt.

(Benefit) provision for income taxes. During the nine-month period ended September 30, 2015, we had a $5.5 million benefit for income taxes, due to a pre-tax loss of $9.4 million, driven by the asset impairment charge and loss on sale of wood mobile units discussed previously in this report. In the prior-year period, we had a $17.6 million provision for tax on pre-tax income of $49.2 million. Our effective income tax rate increased to 58.2% for nine months ended September 30, 2015, compared to 35.9% for the prior-year period. Our effective tax rate in the current period was higher than our prior year tax rate due to the discrete benefit of $25.5 million recorded in the period related primarily to the wood mobile office divestiture.

Net (loss) income. Primarily due to the $66.1 million impairment and divestiture loss and the other income statement activity discussed above, we had a net loss of $3.9 million for the nine months ended September 30, 2015, compared to net income of $31.5 million in the prior-year period.

Wood Mobile Office Divestiture

Revenues and adjusted EBITDA will decrease in the near term compared to prior periods as a result of the wood mobile office divestiture. Historically, the divested assets have contributed $10 million to $12 million in rental revenue per quarter, and we estimate they contributed $46 million in revenue for the year ended December 31, 2014.

We estimate that in the twelve months ended December 31, 2014, the wood mobile office fleet generated approximately $14 million in adjusted EBITDA. However, due to shared costs and infrastructure, the Company estimates the divestiture would have resulted in an approximately $19 million reduction in 2014 adjusted EBITDA, had it occurred prior to the beginning of that year. We further expect the transaction to be modestly dilutive to net income and earnings per share for the balance of 2015.

LIQUIDITY AND CAPITAL RESOURCES

Our business is capital-intensive and requires us to acquire assets before they generate revenues, cash flow and earnings. The assets that we rent have very long useful lives and require relatively little maintenance expenditures. Most of the capital we have deployed in our rental business historically has been used to expand our operations geographically, to increase the number of units available for rent at our existing locations, and to add to the mix of products we offer. During recent years, our operations have generated annual cash flow that exceeds our pre-tax earnings, particularly due to cash flow from operations and the deferral of income taxes caused by accelerated tax depreciation of our fixed assets. Our free cash flow has been positive, even after capital net expenditures for the past five years. This positive cash flow trend continued for the nine-month period ended September 30, 2015. In addition to cash flow generated by operations, our principal current source of liquidity is our Credit Agreement described below.

37

Revolving Credit Facility. On February 22, 2012, we entered into a $900.0 million Credit Agreement with Deutsche Bank AG New York Branch and other lenders party thereto. On December 10, 2014, we amended our Credit Agreement to increase the credit facility to $1.0 billion. The Credit Agreement provides for a five-year, revolving credit facility and matures on February 22, 2017. The obligations of us and our subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets. We funded the ETS Acquisition with funds drawn on our Credit Agreement. At September 30, 2015, we had $663.4 million of borrowings outstanding and $330.1 million of additional borrowing availability under the Credit Agreement. We were in compliance with the terms of the Credit Agreement as of September 30, 2015 and were above the minimum borrowing availability threshold and therefore not subject to any financial maintenance covenants.

Amounts borrowed under the Credit Agreement and repaid or prepaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement bear interest at our option at either: (i) LIBOR plus a defined margin, or (ii) the Agent bank’s prime rate plus a margin. The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans at each measurement date. Based on the pricing grid at September 30, 2015, the applicable margins are 2.0% for LIBOR loans and 1.0% for base rate loans and will be remeasured at the end of the next measurement date, which is within 10 days following the end of each fiscal quarter.

Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of our eligible accounts receivable, eligible container fleet (including containers held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the net orderly liquidation value, as defined in the Credit Agreement, is included in the borrowing base to determine how much we may borrow under the Credit Agreement. The divestiture of the wood mobile offices did not have a material effect on our available borrowings, as the calculated borrowing base currently exceeds the maximum eligibility.

The Credit Agreement provides for U.K. borrowings, which are, at our option, denominated in either Pounds Sterling or Euros, by our U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by our Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary.

The Credit Agreement also contains customary negative covenants, including covenants that restrict our ability to, among other things: (i) allow certain liens to attach to the Company or its subsidiary assets; (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, prepay certain indebtedness or make acquisitions or other investments subject to Payment Conditions (as defined in the Credit Agreement); and (iii) incur additional indebtedness or engage in certain other types of financing transactions. Payment Conditions allow restricted payments and acquisitions to occur without financial covenants as long as we have $250.0 million of pro forma excess borrowing availability under the Credit Agreement. We must also comply with specified financial maintenance covenants and affirmative covenants only if we fall below $100.0 million of borrowing availability levels.

We believe our cash provided by operating activities will provide for our normal capital needs for the next twelve months. If not, we have sufficient borrowings available under our Credit Agreement to meet any additional funding requirements. We monitor the financial strength of our lenders on an ongoing basis using publicly-available information. Based upon that information, we do not presently believe that there is a likelihood that any of our lenders will be unable to honor their respective commitments under the Credit Agreement. Free cash flow was $58.0 million and $81.0 million for the nine-month periods ended September 30, 2015 and 2014, respectively.

Senior Notes. At September 30, 2015, we had outstanding $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the “Senior Notes”). Interest on the Senior Notes is payable semiannually in arrears on September 1 and December 1 of each year.

Operating Activities. Net cash provided by operating activities was $113.7 million for the nine months ended September 30, 2015, compared to $87.8 million in the same period in the prior year, an increase of $26.0 million. Although the nine-month period ended September 30, 2015 reflects a net loss of $3.9 million, compared to net income of $31.5 million in the comparable period in the prior-year period, the difference is due primarily to non-cash items. Non-cash items in the current year include, a $66.1 million asset impairment charge and loss on divestiture, $45.1 million in depreciation and amortization and $10.8 million of share-based compensation expense, offset by a $6.1 million decrease in deferred taxes. Non-cash items in the prior year include $17.3 million in deferred tax expense, $27.9 million of depreciation and amortization and $11.6 million of share-based compensation expense.

38

Excluding the net non-cash income statement items of $118.1 million in the current-year period and $57.0 million in the prior-year period, cash generated by net income increased to $114.1 million, from $88.5 million in the prior-year period. The increase is due primarily to the recently acquired specialty containment business, as well as increased margins in the portable storage business. The change in working capital accounts resulted in cash outflow of $0.4 million in the 2015 period and $0.8 million in the 2014 period, due to normal operating fluctuations.

Investing Activities. Net cash provided by investing activities was $9.0 million for the nine months ended September 30, 2015, compared to net cash used in investing activities of $26.8 million for the same period in 2014. Cash received from the divestiture of the wood mobile offices, less associated deferred revenue and customer deposits was $83.3 million, while cash paid for businesses acquired was $18.6 million in the current-year period and $20.0 million in the prior-year period.

Capital expenditures for our rental fleet were $53.5 million, and proceeds from sale of rental fleet units were $13.3 million for the nine months ended September 30, 2015, compared to capital expenditures of $16.3 million and proceeds of $17.8 million for the same period in 2014. Of the $53.5 million in capital expenditures for the rental fleet, $21.3 million related to our North America business, $16.3 million related to our U.K. business and $16.0 million were specialty containment fleet expenditures. Our expenditures are primarily to meet demand in geographic areas of high utilization for which it does not make economic sense to reposition our fleet and to meet customer demand for specific types of units.

Gross and net capital expenditures for property, plant and equipment were $17.9 million and $15.5 million, respectively, for the nine-month period ended September 30, 2015 compared to gross and net capital expenditures for property, plant and equipment of $11.7 million and $8.3 million, respectively, for the nine-month period ended September 30, 2014. Current year expenditures include costs to implement our new enterprise resource planning platform and general technology upgrades, as well as costs related to our new corporate headquarters.

Financing Activities. Net cash used in financing activities during the nine months ended September 30, 2015 was $124.6 million, compared to $59.8 million for the same period in 2014. We used proceeds from the wood mobile office divestiture, as well as free cash flow to pay down $42.1 million on our lines of credit, purchase $55.8 million of treasury shares and pay $25.3 million in dividends. In the prior year, free cash flow was used to pay down $11.9 million on our line of credit, pay $23.6 million in dividends and purchase $25.5 million of treasury shares.

CONTRACTUAL OBLIGATIONS AND COMMITMENTS

Our contractual obligations primarily consist of our outstanding balance under the Credit Agreement, $200.0 million aggregate principal amount of the Senior Notes and obligations under capital leases. We also have operating lease commitments for: (i) real estate properties for the majority of our locations with remaining lease terms typically ranging from one to five years, (ii) delivery, transportation and yard equipment, typically under a five-year lease with purchase options at the end of the lease term at a stated or fair market value price, and (iii) office related equipment.

At September 30, 2015, primarily in connection with securing our insurance policies, we have provided certain insurance carriers and others with approximately $6.5 million in letters of credit. We currently do not have any obligations under purchase agreements or commitments.

OFF-BALANCE SHEET TRANSACTIONS

We do not maintain any off-balance sheet transactions, arrangements, obligations or other relationships with unconsolidated entities or others that are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

SEASONALITY

Demand from our portable storage customers is somewhat seasonal. Construction customers typically reflect higher demand during months with more temperate weather, while demand for our portable storage units by large retailers is stronger from September through December because these retailers need to store more inventories for the holiday season. Our retail customers usually return these rented units to us in December and early in the following year. In the specialty containment business, demand from customers is typically higher in the middle of the year from March to October, driven by the timing of customer maintenance projects. The demand for rental of our pumps may also be impacted by weather, specifically when temperatures drop below freezing.

CRITICAL ACCOUNTING POLICIES, ESTIMATES AND JUDGMENTS

A comprehensive discussion of our critical accounting policies and management estimates and significant accounting policies are included in the Management’s Discussion and Analysis of Financial Conditions and Results of Operations and in Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

39

There have been no significant changes in our critical accounting policies, estimates and judgments during the nine-month period ended September 30, 2015.

RECENT ACCOUNTING PRONOUNCEMENTS

For discussions of the adoption and potential impacts of recently issued accounting standards, refer to Note 2, “Recent Accounting Pronouncements” to the accompanying condensed consolidated financial statements.

CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING STATEMENTS

This section and other sections of this report contain forward-looking information about our financial results and estimates and our business prospects that involve substantial risks and uncertainties. From time to time, we also may provide oral or written forward-looking statements in other materials we release to the public. Forward-looking statements are expressions of our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historic or current facts. They include words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “will,” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. In particular, these include statements relating to future actions, future performance or results, expenses, the outcome of contingencies, such as legal proceedings, and financial results. Factors that could cause actual results to differ materially from projected results include, without limitation:

• an economic slowdown in the U.S. and/or the U.K. that affects any significant portion of our customer base, or the geographic regions where we operate in those countries;

• our ability to increase revenue and control operating costs;

• our ability to raise or maintain rental rates;

• our ability to leverage and protect our information technology systems;

• changes in the supply and cost of the raw materials we use in refurbishing or remanufacturing storage units;

• competitive developments affecting our industry, including pricing pressures;

• the timing, effectiveness and number of new markets we enter;

• our ability to cross-sell our portable storage and specialty containment products,

• our ability to integrate ETS or other acquisitions;

• our ability to execute the divestiture of the wood mobile offices and achieve the expected benefits from the divestiture;

• our ability to obtain borrowings under our Credit Agreement or additional debt or equity financing on acceptable terms;

• our ability to develop a new scalable enterprise resource platform; and

• our ability to utilize our deferred tax assets.

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from past results and those anticipated, estimated or projected. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise.

In addition to the information set forth in this report, you should carefully consider the factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2014 under the heading “Risk Factors”.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk. As of September 30, 2015, we had $663.4 million of indebtedness under our Credit Agreement, which bears interest at variable rates. The average interest rate applicable to our Credit Agreement was 2.2% for the nine months ended September 30, 2015. Based upon the average amount of our variable rate debt outstanding during the nine months ended September 30, 2015, our annual interest expense would increase by approximately $6.7 million for each one percentage point increase in the interest rate of our lines of credit.

Impact of Foreign Currency Rate Changes. We currently have operations outside the U.S., and we bill those customers primarily in their local currency, which is subject to foreign currency rate changes. Our operations in Canada are billed in the Canadian Dollar, and our operations in the U.K. are billed in Pound Sterling. We are exposed to foreign exchange rate fluctuations as the financial results of our non-U.S. operations are translated into U.S. Dollars. The impact of foreign currency rate changes has historically been insignificant with our Canadian operations, but we have more exposure to volatility with our U.K. operations. In order to help minimize our exchange rate gain and loss volatility, we finance our European entities through our Credit Agreement, which allows us, at our option, to borrow funds locally in Pound Sterling or Euros denominated debt.

40

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, the Company’s disclosure controls and procedures were effective such that the information relating to the Company required to be disclosed in our Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (ii) is accumulated and communicated to the Company’s management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

41

Changes in Internal Controls.

There were no changes in our internal control over financial reporting that have occurred during the fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1A. RISK FACTORS

We refer you to documents filed by us with the SEC, specifically “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, which identify important risk factors that could materially affect our business, financial condition and future results. We also refer you to the factors and cautionary language set forth in the section entitled “Cautionary Statements Regarding Forward-looking Statements” in “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations” of this Quarterly Report on Form 10-Q. This Quarterly Report on Form 10-Q, including the accompanying condensed consolidated financial statements and related notes, should be read in conjunction with such risks and other factors for a full understanding of our operations and financial condition. The risks described in our Form 10-K and herein are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or operating results. The risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 have not materially changed.

The following tables reflect the condensed consolidating financial information of the Company’s subsidiary guarantors of the Senior Notes and its non-guarantor subsidiaries. Separate financial statements of the subsidiary guarantors are not presented because the guarantee by each 100% owned subsidiary guarantor is full and unconditional, joint and several, subject to customary exceptions, and management has determined that such information is not material to investors.
