Through a network of locations in the United States, Canada, United Kingdom and The Netherlands, the company executes an operating strategy of leasing secure, high quality portable storage containers and offices, offering a diversified product line and to delivering excellent customer service. Mobile Mini’s ongoing success in deploying this strategy stems from the company’s consistent attention to a number of key marketing and operational drivers. These include maintaining an internal growth focus, increasing market awareness, offering superior, differentiated products, emphasizing sales and marketing, maintaining a national presence coupled with local service, geographic and customer diversification, employee retention and promotion, and creating a culture dedicated to superior customer service. Since its founding in 1983, Mobile Mini’s diligent focus on these initiatives has driven the company’s expansion from one location to a network of 124 locations and has enabled the company to build a solid financial foundation and positioned Mobile Mini to continue its pattern of market leadership and sustainable growth.

We are reaping the cumulative and enduring benefits of the initiatives implemented throughout the past three years, actions that even in the worst of times enabled Mobile Mini to achieve better than average results (compared to other rental companies), maintain high adjusted EBITDA margins, generate substantial free cash flow and pay down debt. As the economy continues its recovery, we look forward to continued growth in our lease revenues, along with adjusted operating margins and net profit. Most of all, we look forward to once again realizing the full impact of the operating leverage inherent in our business model. What a difference a year makes! 2010 Overview In 2010, business improved as the year progressed and by the fourth quarter, we delivered three sequential quarters of growth in revenues and adjusted EBITDA. In addition, by tightly managing operating expenses we generated $66.2 million in free cash flow (which we define as net cash provided by operating activities, less net cash used in investing activities, excluding the cost of acquisitions).

The sales personnel at our full service branches pursue customers with localized requirements, such as large multi-unit customers and mobile office renters, but primarily work with local contractors where personal contact helps us get the inside track on future start-up and renovation projects. This transition to a bifurcated sales force is still ongoing, but we are now fully staffed and moving into the next phase of our transition which is to more deeply penetrate the outbound call campaign to non-contractors. On the second point, with $385.9 million of excess borrowing availability at year-end and plans to reduce debt further in 2011, we elected to decrease our credit facility by $50 million during the third quarter of 2010 thereby reducing associated unused line fees under our now $850 million line of credit. The confluence of paying down debt, reducing unnecessary availability under our credit facility and replacing our 9¾% senior notes due in 2014 with 77/8% senior notes due in 2020, should reduce ongoing interest expense, while providing increased liquidity and financial flexibility for the better part of this decade. The only financial maintenance covenants in our capital structure relate to our revolving credit agreement, and $55.7 million of debt, after payment of an $8.9 million call premium related to our senior note refinancing in the fourth quarter. Since the acquisition of Mobile Storage Group in June 2008, we have generated free cash flow of $178.5 million and reduced debt by $160.0 million. Central themes of 2010 were once again eliminating costs from the business, improving efficiency and customer service, enhancing our financial flexibility, and keeping capital expenditures to a minimum as we redeploy our rental fleet. We also reinserted ‘new market expansion’ back into our business formula. On the first point, we trimmed more than $13.2 million of operating expenses in 2010. We pursued cost savings, both large and small. For example, additional full-service branches were converted into low-cost operational yards which allow us to leverage the infrastructure costs of one or more nearby fully staffed branches to expand our market reach. As of this writing, of our 124 locations, 36 are operational yards that store, maintain and transport our products and equipment. We further tightened our procurement processes, finding additional savings from service providers and negotiating better terms for insurance and rent. By making the internet a primary go-to advertising medium, we’ve been able to achieve further savings. Our Lean6Sigma team forged ahead with efficiency improvements and our new logistics tools, including routing software and handheld radios, enable our drivers, dispatchers and the sales force to do a better job, less expensively. For most of 2010, our hybrid sales model has been in place. This hybrid model encompasses national sales centers, one each in the U.S. and the U.K. that cater to our non-construction customers including specialized end-user groups like schools, 2 these covenants would only be tested if our excess availability under the facility dips below $100 million. We do not anticipate much of an increase, if at all, in capital expenditures in 2011. As the economy improves and utilization follows suit, we have sufficient lease assets to put on rent to grow our business into the foreseeable future, both at existing locations and those in the planning stage. Since 2008 we have scaled back our fleet by over 28,000 units, but throughout the period we used a measured approach to selling steel storage containers out of our rental fleet because of the exceptionally high returns they generate when on rent and their low cost of upkeep. They can easily be re-positioned to high demand markets and they also maintain their value over time. Although these sales were of different products, the blended margin on the sale of fleet was a very healthy 33.7% in 2010. In mid-2010 we entered three new markets– Omaha, NE, Norfolk/Virginia Beach, VA and Washington, DC – all with low cost operational yards and all by repositioning existing fleet. We are pleased to report that these three new locations were operating profitably by year-end. We’ve identified over 50 additional underserved North American markets as potential Mobile Mini locations and recently announced openings in Albany, NY, Columbus, GA and Des Moines, IA in 2011. We plan to open a total of six in 2011. Once again, we will open low cost operational yards where we can reposition idle fleet to enhance utilization and drive growth. Distinctly Mobile Mini: Customer Service, Our Corporate Culture, Product Differentiation, Diverse Customer Base, Attractive Leasing Economics Mobile Mini has made customer service its hallmark. Not surprisingly, our customers have rated Mobile Mini with a best in class customer loyalty Net Promoter Score. But for us, the best expression of customer loyalty is in repeat business, so we are very proud that approximately 60% of our 2010 leasing revenues came from customers who have done business with us in the past. Creating satisfied, long term and/or repeat customers starts with a capable and effective sales force, and we go to great lengths to enhance each salesperson’s effectiveness through our extensive sales call monitoring, mentoring and training programs. Still another Mobile Mini distinction is product differentiation, especially regarding steel portable storage units. These high quality units provide security, convenience, and come in a broad selection of sizes and configurations. With some 100 3 types of units, ranging from five to 48 feet in length and eight to 10 feet in width, multiple door and interior configurations, and nearly all with our proprietary locking system, we clearly differentiate our products from those of our competitors. ■ have long useful lives exceeding 30 years, relatively low maintenance and high residual values; and ■ produce incremental leasing operating margins of approximately 68% in the North America and 55% in the U.K. In 2010, we served 84,500 customers. Our typical customer rents only one unit, and uses storage containers as a lower cost alternative to renting more warehouse or office space. Our customers encompass just about every kind of enterprise including retail, construction, industrial, medical centers, schools and universities, utilities, distributors, the military, hotels, restaurants, entertainment complexes, and consumers. The uses of our containers and offices are virtually limitless, but they are more commonly used to securely store retail and manufacturing inventory, construction materials and equipment, documents and records, and other goods. From time to time, they are deployed in the aftermath of natural disasters. Our offices, which represent approximately 17% of our fleet, are frequently used as golf clubhouses, first aid units, guard/security units, sales offices and job site offices. There are some very attractive aspects of leasing steel portable storage units; specifically they: ■ provide predictable, recurring revenues from leases with an average duration of approximately 35 months; ■ have average monthly lease rates that recoup our current In closing…. The actions we’ve taken operationally and financially should enhance the operating leverage inherent in our business model as the economy continues to strengthen and our utilization improves. For 2011, we expect to achieve top and bottom line growth, and as noted earlier, enter at least six new markets, and continue to generate additional free cash flow and pay down debt. On behalf of the Board of Directors, I want to thank the entire Mobile Mini team on both sides of the Atlantic for their dedication and hard work that got us through the recession and prepared for our future. We continue to value the confidence of our stockholders, suppliers, customers, noteholders and lenders. Sincerely yours, investment on our remanufactured units within an average of 35 months; Steven G.

Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current events. They include words such as “may”, “plan”, “seek”, “will”, “expect”, “intend”, “estimate”, “anticipate”, “believe” or “continue” or the negative thereof or variations thereon or similar terminology. These forward-looking statements include statements regarding, among other things, our future actions; financial position; management forecasts; efficiencies; cost savings, synergies and opportunities to increase productivity and profitability; income and margins; liquidity; anticipated growth; the economy; business strategy; budgets; projected costs and plans and objectives of management for future operations; sales efforts; taxes; refinancing of existing debt; and the outcome of contingencies such as legal proceedings and financial results.

Important factors that could cause actual results to differ materially from our expectations are disclosed under “Risk Factors” and elsewhere in this Annual Report, including, without limitation, in conjunction with the forward-looking statements included in this Annual Report. These are factors that we think could cause our actual results to differ materially from expected and historical results.

BUSINESS. Mobile Mini, Inc. We are the world’s leading provider of portable storage solutions. We offer a wide range of portable storage products in varying lengths and widths with an assortment of differentiated features such as our patented locking systems, premium doors, electrical wiring and shelving. At December 31, 2010, we operated a network of 121 locations in the United States, Canada, the United Kingdom and The Netherlands. Our portable units provide secure, accessible temporary storage for a diversified customer base, including large and small retailers, con- struction companies, medical centers, schools, utilities, manufacturers and distributors, the U.S. and U.K. military, hotels, restaurants, entertainment complexes and households. Our customers use our products for a wide variety of storage applications, including retail and manufacturing supplies and inventory, temporary offices, construction materials and equipment, documents and records and household goods. We were founded in 1983 and follow a strategy of focusing on leasing rather than selling our portable storage units. We derive most of our revenues from the leasing of portable storage containers, security offices and mobile offices. Leasing revenues represented approximately 89.2% of total revenues for the year ended December 31, 2010. We believe our leasing strategy is highly attractive because the vast majority of our fleet consists of steel portable storage units which: (cid:129) provide predictable, recurring revenues from leases with an average duration of approximately 35 months; (cid:129) have average monthly lease rates that recoup our current investment on our remanufactured units within an average of 35 months; and (cid:129) have long useful lives exceeding 30 years, relatively low maintenance and high residual values. Our total lease fleet has grown significantly over the years to approximately 245,500 units at December 31, 2010. We experienced a significant increase in these units in 2008 when we acquired Mobile Storage Group (MSG). In addition to our leasing business, we also sell new and used portable storage containers and security and mobile offices and provide delivery, installation and other ancillary products and services. Our sales represented 10.3% and 10.0% of total revenues for the twelve months ended December 31, 2009 and 2010, respectively. Our fleet is primarily comprised of remanufactured and differentiated steel portable storage containers that were built according to standards developed by the International Organization for Standardization (ISO), other steel containers, steel offices that we manufacture, and mobile offices. We remanufacture and customize our products by adding our proprietary locking and easy-opening premium door system to our purchased ISO containers and steel security offices. Because they are composed primarily of steel, these assets are characterized by low risk of obsolescence, extreme durability, relatively low maintenance, long useful lives and a history of high-value retention. We also have wood mobile office units in our lease fleet to complement our core steel portable storage containers and steel security offices. We perform maintenance on our steel containers and offices on a regular basis. Repair and maintenance expense for our fleet has averaged 2.7% of lease revenues over the past three fiscal years and is expensed as incurred. We believe our historical experience with leasing rates and sales prices for these assets demonstrates their high-value retention. We are able to lease our portable storage containers at similar rates without regard to the age of the container. In addition, we have sold containers and steel security offices from our lease fleet at an average of 145% of original cost from 1997 through 2010. Industry Overview The storage industry includes two principal segments, fixed self-storage and portable storage. The fixed self- storage segment consists of permanent structures located away from customer locations used primarily by consumers to temporarily store excess household goods. We do not participate in the fixed self-storage segment. We do offer some non-fixed self-storage in secure containers from our fleet at some of our locations in the U.S. and the U.K. 4 The portable storage segment in which our business operates differs from the fixed self-storage segment in that it brings the storage solution to the customer’s location and addresses the need for secure, temporary storage with immediate access to the storage unit. The advantages of portable storage include convenience, immediate accessibility, better security and lower price. In contrast to fixed self-storage, the portable storage segment is primarily used by businesses. This segment of the storage industry is highly fragmented and remains primarily local in nature. We believe the portable storage rental market in the U.S. exceeds $1.5 billion in revenue annually. Portable storage solutions include containers, record vaults and van trailer units. Although there are no published estimates of the size of the portable storage segment, we believe portable storage containers are achieving increased storage market share compared to other storage options and that this segment is expanding because of an increasing awareness that only containers provide both ground level access and better protect against damage caused by wind or water than do other portable storage alternatives. As a result, containers can meet the needs of a diverse range of customers. Portable storage units such as ours provide ground level access, higher security and improved aesthetics compared with certain other portable storage alternatives such as van trailers. Our products also serve the mobile office industry. This industry provides mobile offices and other modular structures and we believe this industry generates approximately $3.0 billion in revenue annually in North America. We offer steel security offices, combination steel office/storage units and mobile offices in varying lengths and widths to serve the various requirements of our customers. We also offer portable record storage units and many of our regular storage units are used for document and record storage. We believe the documents and records storage industry will continue to grow as businesses continue to generate substantial paper records that must be kept for extended periods. Our goal is to continue to be the leading provider of portable storage solutions in North America and the U.K. We believe our competitive strengths and business strategy will enable us to achieve this goal. Competitive Strengths Our competitive strengths include the following: Market Leadership. At December 31, 2010, we maintained a total lease fleet of approximately 245,500 units and are the largest provider of portable storage solutions in North America and the U.K. We are creating brand awareness and believe the name “Mobile Mini” is associated with high quality portable storage products, superior customer service and value-added storage solutions. We have historically achieved significant growth in new and existing markets by capturing market share from competitors and by creating demand among businesses and consumers who were previously unaware of the availability of our products to meet their storage requirements. Superior, Differentiated Products. We offer the industry’s broadest range of portable storage products, with many features that differentiate our products from those of our competition. We remanufacture used ISO containers and have designed and manufactured our own portable storage units. These capabilities allow us to offer a wide range of products and proprietary features to better meet our customers’ needs, charge premium lease rates and gain market share from our competitors, who offer more limited product selections. Our portable storage units vary in size from 5 to 48 feet in length and 8 to 10 feet in width. The 10-foot wide units we manufactured provide 40% more usable storage space than the standard eight-foot-wide ISO containers offered by our competitors. The vast majority of our products have our patented locking system and multiple door options, including easy-open door systems. In addition, we offer portable storage units with electrical wiring, shelving and other customized features. This differentiation allows us to charge premium rental rates compared to the rates charged by our competition. Sales and Marketing Emphasis. We target a diverse customer base and, unlike most of our competitors, have developed sophisticated sales and marketing programs enabling us to expand market awareness of our products and generate strong internal growth. We have a dedicated commissioned sales team and we assist them by providing them with our highly customized contact management system and intensive sales training programs. We monitor our salespersons’ effectiveness through our extensive sales call monitoring and sales mentoring and training programs. Our website is an integral part of our sales and marketing approach as well as 5 our advertising online, and in yellow pages and direct-mail media. Our website includes customer focused features such as product video tours, online payment capabilities and online real time sales inquiries, enabling customers to chat live with our salespeople. National Presence with Local Service. We have the largest national network of locations for portable storage solutions in the U.S. and the U.K. and believe it would be difficult for our competitors to replicate this network. We have invested significant capital developing a national network of locations that serves most major metropolitan areas in the U.S. and the U.K. We have differentiated ourselves from our local competitors and made replication of our presence difficult by developing our branch network both through opening branches in multiple cities and purchasing competitors in key markets. The difficulty and time required to obtain the number of units and locations necessary to support a national operation would make establishing a large competitor difficult. In addition, there are difficulties associated with recruiting and hiring an expe- rienced management team such as ours that has strong industry knowledge and local relationships with customers. Our network of local branches and operational yards allows us to develop and maintain relation- ships with our local customers, while providing a level of service to regional and national companies that is made possible by our nationwide presence. Our local managers, sales force and delivery drivers develop and maintain critical personal relationships with customers that benefit from access to our wide selection of products that we have available. Additionally, our National Sales Center (NSC) coordinates inbound calls from non-construction customers and oversees outbound marketing campaigns. Geographic and Customer Diversification. At December 31, 2010, we operated from 121 locations of which 98 were located in the U.S., three in Canada, 19 in the U.K., and one in The Netherlands. We served approximately 84,500 customers from a wide range of industries in 2010. Our customers include large and small retailers, construction companies, medical centers, schools, utilities, manufacturers and distributors, the U.S. and U.K. militaries, government agencies, hotels, restaurants, entertainment complexes and households. Our diverse customer base demonstrates the broad applications for our products and our opportunity to create future demand through targeted marketing. In 2010, our largest and our second-largest customers accounted for 2.1% and 1.2% of our leasing revenues, respectively, and our twenty largest customers accounted for approximately 7.5% of our leasing revenues. During 2010, approximately 61.4% of our customers rented a single unit. We believe this diversity also helps us to better weather economic downturns in individual markets and the industries in which our customers operate. Customer Service Focus. We believe the portable storage industry is particularly service intensive. Our entire organization is focused on providing high levels of customer service, and we have salespeople both at the national level and at our branch locations to better understand our customer’s needs. We have trained our sales force to focus on all aspects of customer service from the sales call onward. We differentiate ourselves by providing security, convenience, high product quality, differentiated and broad product selection and avail- ability, and competitive lease rates. We conduct training programs for our sales force to assure high levels of customer service and awareness of local market competitive conditions. Additionally, we use a Net Promoter Score (NPS) system to measure and enhance our customer service. We use NPS to measure customer satisfaction each month, rental-by-rental, in real time through surveys conducted by a third party. We then use customer feedback to drive service improvements across the company, from our branches to our corporate headquarters. Our Customer Relationship Management (CRM) system also increases our responsiveness to customer inquiries and enables us to efficiently monitor our sales force’s performance. Approximately 59.4% of our 2010 leasing revenues were derived from repeat customers, which we believe is a result of our superior customer service. Customized Enterprise Resource Planning (ERP) System. We have made significant investments in an ERP system supporting our U.S. and U.K. operations. These investments enable us to optimize fleet utilization, control pricing, capture detailed customer data, easily evaluate credit approval while approving it quickly, audit company results reports, gain efficiencies in internal control compliance and support our growth by projecting near-term capital needs. In addition, we believe this system gives us a competitive advantage over smaller and less sophisticated local and regional competitors. Our ERP system allows us to carefully monitor, on a real time basis, the size, mix, utilization and lease rates of our lease fleet branch by branch. Our systems 6 also capture relevant customer demographic and usage information, which we use to target new customers within our existing and new markets. Business Strategy Our business strategy consists of the following: Focus on Core Portable Storage Leasing Business. We focus on growing our core storage leasing business, which accounted for 81% of our fleet at December 31, 2010, because it provides recurring revenue and high margins. We believe that we can continue to generate substantial demand for our portable storage units throughout North America, the U.K. and The Netherlands. Maintain Strong EBITDA Margins. One of the tools we use internally to measure our financial performance is EBITDA margins. We calculate this number by first calculating EBITDA, which we define as net income before interest expense, debt restructuring or extinguishment expense, provision for income taxes, depreciation and amortization. In comparing EBITDA from year to year, we may further adjust EBITDA to exclude the effect of what we consider transactions or events not related to our core business operations to arrive at adjusted EBITDA. We define our EBITDA margins as EBITDA or adjusted EBITDA, divided by our total revenues, expressed as a percentage. We continued to aggressively manage this margin even during the recent downturn in the economic environment. Our objective is to maintain a relatively stable EBITDA margin through adjustments to our cost structure as revenues change. Generate Strong Internal Growth. We focus on increasing the number of portable storage units we lease at our existing branches to both new and repeat customers. We have historically generated strong internal growth within our existing markets by implementing our sophisticated sales and marketing programs aimed to increase brand recognition, expand market awareness of the uses of portable storage and differentiate our superior products from our competitors. Through our NSC, we are able to deploy sophisticated marketing campaigns and customer tracking strategies to generate new sales and support local branch operations. Our technology coupled with a hybrid sales strategy allows us to bifurcate our customer base into customers that need a local sales presence and those that can be supported and grown by our centralized NSC sales force. Through the NSC and our hybrid sales strategy we are able to target sales campaigns by specific markets, customer type and seasonal needs as well as adjust pricing simultaneously on a national basis. Opportunistic Geographic Expansion. We believe we have attractive geographic expansion opportu- nities and have identified over 50 additional markets in North America where we believe demand for portable storage containers is underdeveloped. We have developed a proven market strategy that allows us to enter markets by either redeploying existing containers to new markets that can be serviced by nearby full-service branches or by acquiring the lease fleet assets of a small local portable storage business and overlaying our business model onto the new branch. Although we may make opportunistic acquisitions in various markets from time to time, we are currently focused on optimizing our existing markets and entering new markets through greenfield operational yards. From these start-up operational yards we are able to redeploy existing units and deliver product into new markets without the overhead and staffing of a full-service branch. We opened three greenfield locations in 2010. Continue to Enhance Product Offering. We continue to enhance our existing products to meet our customers’ needs and requirements. We have historically been able to introduce new products and features that expand the applications and overall market for our storage products. For example, over the years we have introduced a number of innovative products including a 10-foot-wide storage unit, a record storage unit and a 10-by-30-foot steel combination storage/office unit to our fleet. The record storage unit provides highly secure, on-site and easy access to archived business records close at hand. In addition to our steel container and steel security offices, we have also added wood mobile offices as a complementary product to better serve our customers. We have also made continuous improvements (for example, making it easier to use in colder climates) to our patented locking system over the years. Currently, the 10-foot-wide unit, the record storage unit and the 10-by-30-foot steel combination storage/office unit are exclusively offered by Mobile Mini. We believe our proprietary designed and manufactured units increase our ability to service our customers’ needs and expand demand for our portable storage solutions. 7 Products We provide a broad range of portable storage products to meet our customers’ varying needs. Our products are managed and our customers are serviced by our team at each of our locations, including management, sales personnel and yard facility employees. Some features of our different products are listed below: (cid:129) Remanufactured and Modified Steel Storage Containers. We purchase used ISO containers from leasing companies, shipping lines and brokers. These containers were originally built to ISO standards and are eight feet wide, 8’6” to 9’6” high and 20, 40 or 45 feet long. After acquisition, we remanufacture and modify these ISO containers at our locations. Remanufacturing typically involves cleaning, removing rust and dents, repairing floors and sidewalls, painting, adding our signs and further customizing them by adding our proprietary easy opening door system and our patented locking system. Modification typically involves splitting some containers into 5-, 10-, 15-, 20- or 25-foot lengths. We have also manufactured portable steel storage containers for our lease fleet and for sale, including our 10-foot-wide containers. We generally purchase used ISO containers when they are 10 to 12 years old, a time at which their useful life as an ISO shipping container has normally expired according to the standards promulgated by the International Organization for Standardization. Because we do not have the same stacking and strength requirements that apply in the ISO shipping industry, we have no need for these containers to meet ISO standards. If we need to purchase ISO containers, as we have in the past, we believe we would be able to procure them at competitive prices because of our volume purchasing power. (cid:129) Steel Security Office and Steel Combination Offices. We buy and historically have manufactured steel security office/storage combination and security office units that range from 10 to 40 feet in length. We offer these units in various configurations, including office and storage combination units that provide a 10- or 15-foot office with the remaining area available for storage. Our office units provide the advantage of ground accessibility for ease of access and high security in an all-steel design. Our European products include canteen units and drying rooms for the construction industry. For customers with space limitations, the office/canteen units can also be stacked two high with stairs for access to the top unit. These office units are equipped with electrical wiring, heating and air conditioning, phone jacks, carpet or tile, high security doors and windows with security bars or shutters. Some of these offices are also equipped with sinks, hot water heaters, cabinets and restrooms. (cid:129) Wood Mobile Offices. We offer wood mobile office units, which range from 8 to 24 feet in width and 20 to 60 feet in length, and which we purchase from manufacturers. These units have a wide range of exterior and interior options, including exterior stairs or ramps, awnings and skirting. These units are equipped with electrical wiring, heating and air conditioning, phone jacks, carpet or tile and windows with security bars. Many of these units contain restrooms. (cid:129) Steel Records Storage Containers. We market proprietary portable records storage units that enable customers to store documents at their location for easy access, or at one of our facilities. Our units are 10.5 feet wide and are available in 12 and 23-foot lengths. The units feature high-security doors and locks, electrical wiring, shelving, folding work tables and air filtration systems. We believe our products are a cost- effective alternative to mass warehouse storage, with a high level of fire and water damage protection. (cid:129) Van Trailers & Other — Non-Core Storage Units. Our acquisitions typically entail the purchase of small companies with lease fleets primarily comprised of standard ISO containers. However, many of these companies also have van trailers and other storage products, which we believe do not have the same advantages as standard containers. It is our goal to dispose of these units from our fleet either as their initial rental period ends or within a few years. We do not remanufacture these products. See “Product Lives and Durability — Van Trailers — Non-Core Storage Units” below. At December 31, 2010, van trailers com- prised less than 0.2% of our lease fleet net book value. We protect our products and brands through the use of trademarks and patents. In particular, we have patented our proprietary door locking system. In 2003 and 2006, we were issued United States patents in connection with our Container Guard Lock and our tri-cam locking system design. In 2006, we applied in several countries for patents 8 for improvements or modifications to our tri-cam locking systems. These applications have been approved in Europe and China and are under review in the United States and other countries. Product Lives and Durability Our steel portable storage containers, steel security offices, and wood mobile offices have estimated useful lives of 30 years, 30 years, and 20 years, respectively, from the date we build or acquire and remanufacture them, with residual values of our per-unit investment ranging from 50% for our mobile offices to 55% for our core steel products. Van trailers, which comprised 0.2% of the net book value of our lease fleet at December 31, 2010, are depreciated over seven years to a 20% residual value. For the past three fiscal years, our cost to repair and maintain our lease fleet units averaged approximately 2.7% of our lease revenues. Repainting the outside of storage units is the most common maintenance item. We maintain our steel containers on a regular basis by painting them with rust inhibiting paint, removing rust, and occasionally replacing the wooden floor or a rusted panel as they come off rent and are ready to be leased again. This periodic maintenance keeps the container in essentially the same condition as after we initially remanufactured it and is designed to maintain the unit’s value and rental rates comparable to new units. Approximately 10.0% of our 2010 revenue was derived from sales of our units. Because the containers in our lease fleet do not significantly depreciate in value, we have no systematic program in place to sell lease fleet containers as they reach a certain age. Instead, most of our container sales involve either highly customized containers that would be difficult to lease on a recurring basis, or containers that we have not remanufactured. In addition, due primarily to availability of inventory at various locations at certain times of the year, we sell a certain portion of containers and offices from the lease fleet. Our gross margins typically increase for containers that have been in our lease fleet for greater lengths of time prior to sale, because although these units have been depreciated based upon a 30 year useful life and 55% residual value (1.5% per year), in most cases a unit’s fair market value may not decline by nearly that amount due to the nature of the assets and our maintenance policy. The following table shows the gross margin on containers and steel security offices sold from inventory (which we call our sales fleet) and from our lease fleet from 1997 through 2010 based on the length of time in the lease fleet.

For manufactured units, cost includes our manufacturing cost and the freight charges to the branch location where the unit is first placed into service. (2) Includes sales of raw ISO containers. Appraisals on our fleet are conducted on a regular basis by an independent appraiser selected by our lenders. The appraiser does not differentiate in value based upon the age of the container or the length of time it has been in our fleet. The latest orderly liquidation value appraisal was conducted in April 2010 by AccuVal Associates, Incorporated. Based on this appraisal, on which our borrowings under our revolving credit facility are based, our lease fleet liquidation appraisal value as of December 31, 2010, is approximately $818.5 million. 9 Because steel storage containers substantially keep their value when properly maintained, we are able to lease containers that have been in our lease fleet for various lengths of time at similar rates, without regard to the age of the container. Our lease rates vary by the size and type of unit leased, length of contractual term, custom features and the geographic location of our branch at which the lease is originated. While we focus on service and security as a main differentiation of our products from our competitors, pricing competition, market conditions and other factors can influence our leasing rates. The following chart shows the average monthly lease rate that we currently receive for various types of containers that have been in our lease fleet for various periods of time. We have added our 10-foot-wide containers and security offices to the fleet and those types of units are not included in this chart. This chart includes the eight major types of containers in the fleet, but specific details of such type of unit are not provided due to competitive considerations. Type 1 . . . .

Some of the units added to our lease fleet during recent years through our acquisitions program have lower lease rates than the rates we typically obtain because the units remain on lease under terms (including lower rental rates) that were in place when we obtained the units in acquisitions. We periodically review our depreciation policy against various factors, including the following: (cid:129) results of our lenders’ independent appraisal of our lease fleet; (cid:129) practices of the major competitors in our industry; (cid:129) our experience concerning useful life of the units; (cid:129) profit margins we are achieving on sales of depreciated units; and (cid:129) lease rates we obtain on older units. In 2009, some of the steel containers in our lease fleet were older than the 25 year originally assigned useful life. In April 2009, we evaluated our depreciation policy on steel units and changed their estimated useful life to 30 years with an estimated residual value of 55%, which effectively results in continual depreciation on these units at the same annual rate of book value as our previous depreciation policy of 25 year life and 62.5% residual value. This change had an immaterial impact on our consolidated financial statements at the date of the change in estimate. 10 Our depreciation policy for our lease fleet uses the straight-line method over the units’ estimated useful life, after the date we put the unit in service, and the units are depreciated down to their estimated residual values. Steel Storage, Steel Security Office and Steel Combination Offices. Our steel products are our core leasing units and include portable storage units, whether manufactured or remanufactured ISO containers, steel security office and office/storage combination units. Our steel units are depreciated over 30 years with an estimated residual value of 55%. Wood Mobile Offices. Because of the wood structure of these units, they are more susceptible to wear and tear than steel units. We depreciate these units over 20 years down to a 50% residual value (2.5% per year), which we believe to be consistent with most of our major competitors in this industry. Wood mobile office units lose value over time and we may sell older units from time to time. At the end of 2010, all of our wood mobile offices were less than eleven years old. These units, excluding those units acquired in acquisitions, are also more expensive than our storage units, causing an increase in the average carrying value per unit in the lease fleet over the last ten years. The operating margins on mobile offices are lower than the margins on steel containers. However, mobile offices are rented using our existing infrastructure and therefore provide incremental returns far in excess of our fixed expenses. These returns add to our overall profitability and operating margins. Van Trailers and Other — Non-Core Storage Units. At December 31, 2010, van trailers made up less than 0.2% of the net book value of our lease fleet. When we acquire businesses in our industry, the acquired businesses often have van trailers and other manufactured storage products that we believe do not offer customers the same advantages as our core steel container storage product. We depreciate our van trailers over 7 years to a 20% residual value. We often attempt to sell most of these units from our fleet as they come off rent or within a few years after we acquire them. We do not utilize our resources to remanufacture these products and instead resell them. Lease Fleet Configuration Our lease fleet is comprised of over 100 different configurations of units. Depending on fleet utilization, we add units to our fleet through purchases of used ISO containers and containers obtained through acquisitions, both of which we remanufacture and customize. We also purchase new manufactured mobile offices in various configurations and sizes, and manufacture our own custom steel units. Due to the number of units acquired in the MSG transaction and the current economic environment, we do not anticipate needing to purchase or acquire containers or offices to remanufacture or customize until our fleet utilization returns to historic levels. Our initial cost basis of an ISO container includes the purchase price from the seller, the cost of remanufacturing, which can include removing rust and dents, repairing floors, sidewalls and ceilings, painting, signage and installing new doors, seals and a locking system. Additional modifications may involve the splitting of a unit to create several smaller units and adding customized features. The restoration and modification processes do not necessarily occur in the same year the units are purchased or acquired. We procure larger containers, typically 40-foot units, and split them into two 20-foot units or one 25-foot and one 15-foot unit, or other configurations as needed, and then add new doors along with our patented locking system and sometimes add custom features. In addition, we also sell units from our lease fleet to our customers. 11 The table below outlines those transactions that effectively maintained the net book value of our lease fleet at $1.1 billion at December 31, 2009, and $1.0 billion at December 31, 2010: Dollars Units (In thousands) Lease fleet at December 31, 2009, net. . . . . . . . . . . . . . . . . . . . . . . . . . . . . $1,055,328 Purchases: 257,208 Container purchases including freight . . . . . . . . . . . . . . . . . . . . . . . . . . . 263 Manufactured units: Steel security offices . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

In order to effectively manage this business across different geographic areas, we divide our one business segment into smaller management areas we call divisions, regions and branches. Each of our branches generally has similar economic characteristics covering all products leased or sold, including similar customer base, sales personnel, advertising, yard facilities, general and administrative costs and branch management. Further financial information by geography is provided in Note 16 to the Consolidated Financial Statements appearing in Item 8 of this report. In the U.S. particularly, we locate our branches in markets with attractive demographics and strong growth prospects. Within each market, we have located our branches in areas that allow for easy delivery of portable storage 12 units to our customers over a wide geographic area. In addition, when cost effective, we seek locations that are visible from high traffic roads in order to advertise our products and our name. Our branches maintain an inventory of portable storage units available for lease, and some of our older branches also provide on-site storage of units under lease at the branch. At December 31, 2010, we operated 121 locations of which 98 were located in the U.S., three in Canada, 19 in the U.K., and one in The Netherlands. We currently have 67 branches in the U.S., one branch in Canada, 17 branches in the U.K. and one branch in The Netherlands. Additionally, we have properties we call operational yards from which we can service a local market and store and maintain our products and equipment. We continue to evaluate our branch operations and where it becomes operationally feasible, we convert some of our branches to operational yards to further reduce expenses. These operational yards do not have branch managers or sales people, but typically have a dispatcher and drivers assigned to them. Likewise, in order to enter new markets we will open new operational yards that can be serviced by nearby full-service branches. Each branch has a branch manager who has overall supervisory responsibility for all activities of the branch. Many branch managers also oversee operational yards that reside within their geographic area. Branch managers report to regional managers who each generally oversee multiple branches. Our regional managers, in turn, report to one of our operational senior vice presidents (called a managing director in Europe). Performance based incentive bonuses are a substantial portion of the compensation for these senior vice presidents, regional managers and branch managers. Each branch has its own dedicated sales staff and a transportation department that delivers and picks up portable storage units from customers. Each branch has delivery trucks and forklifts to load, transport and unload units and a storage yard staff responsible for unloading and stacking units. Steel units can be stored by stacking them to maximize usable ground area. Some of our larger branches also have a fleet maintenance department to maintain the branch’s trucks, forklifts and other equipment. Our other branches perform preventive maintenance tasks, but outsource major repairs and other maintenance requirements. Sales and Marketing We implemented a hybrid sales model consisting of a dedicated sales staff at all of our branch locations as well as at our NSC. Our local sales staff builds and strengthens relationships with local customers in each market with particular emphasis on contractors and construction-related customers, who tend to demand local salesperson presence. Our NSC handles inbound calls from new customers and leads sales campaigns to existing customers not serviced by branch sales personnel. In addition, the NSC initiates outbound marketing calls to solicit new customers. Our sales staff at the NSC work with our local branch managers, dispatchers and sales personnel to ensure customers receive integrated first class service from initial call to delivery. Our branch sales staff, national sales center and sales management team at our headquarters and other locations conduct sales and marketing on a full-time basis. We believe that offering local salesperson presence for customers along with the efficiencies of a centralized sales operation for customers not needing a local sales contact will continue to allow us to provide high levels of customer service and serve all of our customers in a dedicated, efficient manner. Our sales people handle all of our products and we do not maintain separate sales forces for our various product lines. Our sales and marketing force provides information about our products to prospective customers by handling inbound calls and by initiating outbound marketing calls. We have ongoing sales and marketing training programs covering all aspects of leasing and customer service. Our branches communicate with one another and with corporate headquarters through our ERP system and our customer relationship management software and tools. This enables the sales team to share leads and other information and permits management to monitor and review sales and leasing productivity on a branch-by-branch basis. We improve our sales efforts by recording and rating the sales calls made and received by our trained sales force. Our sales employees are compensated largely on a commission basis. Our nationwide presence in the U.S. and the U.K. allows us to offer our products to larger customers who wish to centralize the procurement of portable storage on a multi-regional or national basis. We are well equipped to meet these customers’ needs through our National Account Program, which centralizes and simplifies the procurement, rental and billing process for those customers. Approximately 1,100 U.S. customers and 60 European customers 13 currently participate in our National Account Program. We also provide our national account customers with service guarantees, which assure them they will receive the same high level of customer service from any of our branch locations. This program has helped us succeed in leveraging customer relationships developed at one branch throughout our branch system. We focus an increasing portion of our marketing expenditures on internet-based initiatives with web-based products and services for both existing customers and potential customers. We also advertise our products in the yellow pages and have historically used a targeted direct mail program which described our products and features and highlighted the advantages of portable storage. Customers During 2010, approximately 84,500 customers leased our portable storage products. Our customer base is diverse and consists of businesses in a broad range of industries. In 2010, our largest and second largest customers accounted for 2.1% and 1.2% of our leasing revenues, respectively, and our 20 largest customers accounted for approximately 7.5% of our leasing revenues. During 2010, approximately 61.4% of our customers rented a single unit. Based on an independent market study, we believe our customers are engaged in a vast majority of the industries identified in the four-digit Standard Industrial Classification (SIC) manual published by the U.S. Bureau of the Census. We target customers who can benefit from our portable storage solutions either for seasonal, temporary or long-term storage needs. Customers use our portable storage units for a wide range of purposes. The following table provides an overview of our customers and how they use our portable storage, combination storage/office and mobile office units as of December 31, 2010: Business Consumer service Approximate Percentage of Units on Lease Representative Customers and retail businesses . . . . . 34.2% Construction . . . . . . . . . . . . . 30.5% Industrial and commercial . . . 19.4% Government and institutions . . 10.9% Department, drug, grocery and strip mall stores, hotels, restaurants, dry cleaners and service stations General, electrical, plumbing and mechanical contractors, landscapers, residential homebuilders and equipment rental companies Distributors, trucking and utility companies, finance and insurance companies, real estate brokers and film production companies Schools, hospitals, medical centers, military, Native American tribal governments and reservations and national, state, county and local governmental agencies Consumers . . . . . . . . . . . . . . 5.0% Homeowners 14 Typical Application Inventory storage, supplies, record storage and seasonal needs Equipment and materials storage and job offices Raw materials, equipment, record storage, in-plant office and seasonal needs Athletic equipment, military storage, disaster preparedness, supplier, record storage, security office, supplies, equipment storage, temporary office space and seasonal needs Backyard storage and storage of household goods during relocation or renovation; storage at our location Remanufacturing We continue to remanufacture used ISO containers by adding our proprietary locking and easy-opening door systems at some of our branch locations. Our differentiated product offering allows us to provide a broad selection of products to our customers and distinguishes our products from our competitors. If needed in the remanufacturing process, we purchase raw materials such as steel, vinyl, wood, glass and paint, which we use in our remanufacturing and restoration operations. We typically buy these raw materials on a purchase order basis as we do not have long- term contracts with vendors for the supply of any raw materials. Historically, we built new steel portable storage units, steel security offices and other custom-designed steel structures as well as remanufactured used ISO containers at our Maricopa, Arizona facility. After integrating the assets and operations we acquired in the MSG acquisition, we leveraged our combined fleet and restructured our manufacturing operations, reducing overhead and capital expenditures for our lease fleet. We accomplished this primarily by reducing our work force at our Maricopa, Arizona manufacturing facility in December 2008 by approximately 90%, in addition to reducing manufacturing and remanufacturing staff at other locations. Additionally, we essentially halted new production activities other than completing existing work in process assignments. For the near future, we expect our Maricopa, Arizona facility, with a limited staff, will predominately be used for building custom units, maintenance on our existing fleet and storage for excess lease fleet units. Vehicles At December 31, 2010, we had a fleet of 728 delivery trucks, of which 608 were owned and 120 were leased. We use these trucks to deliver and pick up containers at customer locations. We supplement our delivery fleet by outsourcing delivery services to independent haulers when appropriate. Enterprise Resource Planning and Customer Relationship Management Systems We operate a highly customized ERP and CRM system through which key operational and financial information is made available on a daily basis. Our management team uses this information to monitor closely current business activities. We also use the customized ERP system to improve and optimize lease fleet utilization, improve the effectiveness of our sales and marketing programs and to allow international growth by using the same ERP system throughout the company. The ERP, CRM and all our other systems are available throughout our branch network through a high performance global network. Our Tempe, Arizona corporate headquarters and each branch can enter data into the system and access data on a real-time basis. We generate weekly management reports by branch with leasing volume, fleet utilization, lease rates and fleet movement. These reports allow management to monitor each branch’s performance on a daily, weekly and monthly basis. We track each portable storage unit by its serial number. Lease fleet and sales information are entered in the ERP system daily at the branch level and verified through physical inventories by branch or corporate employees. Salespeople also use the CRM system to track customer leads and other sales data, including information about current and prospective customers. Members of our management team can access all of these systems and databases throughout each day at all of our locations or remotely. Our ERP system is comprised of third-party licensed software and a number of proprietary custom enhancements. We have made significant investments in our ERP and CRM systems over the years, and we intend to continue such investments to further optimize the features of these systems for both our North American and European operations. Lease Terms Under our lease agreements, each lease has an original intended length of term at inception. However, if the customer keeps the leased unit beyond the original intended term, the lease continues on a month-to-month basis until cancelled by the customer. At the end of 2010, our steel storage containers initially have an average intended term of approximately 7 months at inception, however the average duration for these leases that have fulfilled their term agreement was 35 months to date. Our security, security/storage and mobile offices typically have an average intended lease term of approximately nine months. The average duration of all office leases that have fulfilled their term agreement was 24 months in 2010. Our leases provide that the customer is responsible for the cost of delivery and pickup at lease inception. Our leases specify that the customer is liable for any damage done to the unit beyond ordinary wear and tear. However, our customers may purchase a damage waiver from us to avoid this liability in 15 certain circumstances. This provides us with an additional source of recurring revenue. Any customer’s possessions stored within a portable storage unit are typically the responsibility of that customer. Competition We face competition from several local and regional companies, as well as from national companies, in all of our current markets. We compete with several large national and international companies in our mobile office product line. Our competitors include lessors of storage units, mobile offices, used van trailers and other structures used for portable storage. We also compete with conventional fixed self-storage facilities. We compete primarily in terms of security, convenience, product quality, broad product selection and availability, lease rates and customer service. In our core portable storage business, we typically compete with Williams Scotsman, Elliot Hire, PODS, Pac-Van, 1-800-PACK-RAT, LLC, Haulaway Storage Containers, Inc., Moveable Cubicle, Speedy Hire, and a number of other national, regional and local competitors. In the mobile office business, we typically compete with ModSpace, Williams Scotsman, McGrath RentCorp and other national, regional and local companies. Employees As of December 31, 2010, we employed approximately 1,458 full-time employees in the following major categories: Management. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 153 Administrative . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 308 Sales and marketing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 278 Manufacturing and mechanics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 82 Drivers, dispatch and yard . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 637 Seasonality Demand from some of our customers is somewhat seasonal. Demand for leases of 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 leased units to us in December and early in the following year. This seasonality has historically caused lower utilization rates for our lease fleet and a marginal decrease in cash flow during the first quarter of each year.

RISK FACTORS A continued economic slowdown, particularly in the non-residential construction sector of the economy, could reduce demand from some of our customers, which could negatively impact our financial results. The recent recession has caused disruptions and extreme volatility in global financial markets and increased rates of default and bankruptcy, and has reduced demand for portable storage and mobile offices. These events have 16 also caused substantial volatility in the stock market and layoffs and other restrictions on spending by companies in almost every business sector. These events could continue to impact our business in a variety of ways, including: (cid:129) reduction in consumer and business spending, which would result in a reduction in demand for our products; (cid:129) a negative impact on the ability of our customers to timely pay their obligations to us or our vendors to timely supply services, thus reducing our cash flow; and (cid:129) an increase in counterparty risk. Additionally, at the end of 2009 and 2010, customers in the construction industry, primarily in non-residential construction, accounted for approximately 28% and 31%, respectively, of our leased units. If the current economic slowdown in the non-residential construction sector continues, we may continue to experience less demand for leases and sales of our products. Because most of the cost of our leasing business is either fixed or semi- variable, our margins will contract if revenue continues to fall without similar changes in expenses, which may be difficult to achieve, and which ultimately may result in having a material adverse effect on our financial condition. Our operational measures designed to increase revenue while continuing to control operating costs may not generate the improvements and efficiencies we expect and may impact customers. We have responded to the economic slowdown by employing a number of operational measures designed to increase revenue while continuing to pursue our strategy of reducing operating costs where available. Additionally, our hybrid sales strategy is designed to meet customer needs and drive revenue growth but differs from our historic sales structure. The extent to which these strategies will achieve the desired goals and efficiencies in 2011 and beyond is uncertain, as their success depends on a number of factors, some of which are beyond our control. Even if we carry out these measures in the manner we currently expect, we may not achieve the improvements or efficiencies we anticipate, or on the timetable we anticipate. There may be unforeseen productivity, revenue or other consequences resulting from our strategies that will adversely affect us. Therefore, there can be no guarantee that our strategies will prove effective in achieving desired profitability or margins. Additionally, these strategies may have adverse consequences if our cost cutting and operational changes are deemed by customers to adversely impact product quality or service levels. Global capital and credit markets conditions could have an adverse effect on our ability to access the capital and credit markets, including via our credit facility. In 2009, due to the disruptions in the global credit markets, liquidity in the debt markets was materially impacted, making financing terms for borrowers less attractive or, in some cases, unavailable altogether. Renewed disruptions in the global credit markets or the failure of additional lending institutions could result in the unavailability of certain types of debt financing, including access to revolving lines of credit. We monitor the financial strength of our larger customers, derivative counterparties, lenders and insurance carriers on a periodic basis using publicly available information in order to evaluate our exposure to those who have or who we believe may likely experience significant threats to their ability to adequately service our needs. While we engage in borrowing and repayment activities under our revolving credit facility on an almost daily basis and have not had any disruption in our ability to access our revolving credit facility as needed, the current credit market conditions could eventually increase the likelihood that one or more of our lenders may be unable to honor its commitments under our revolving credit facility, which could have an adverse effect on our business, financial condition and results of operations. Additionally, in the future we may need to raise additional funds to, among other things, fund our existing operations, improve or expand our operations, respond to competitive pressures, or make acquisitions. If adequate funds are not available on acceptable terms, we may be unable to meet our business or strategic objectives or compete effectively. If we raise additional funds by issuing equity securities, stockholders may experience dilution of their ownership interests, and the newly issued securities may have rights superior to those of the common stock. If we raise additional funds by issuing debt, we may be subject to further limitations on our operations arising out of the agreements governing such debt. If we fail to raise capital when needed, our business will be negatively affected. 17 We face intense competition that may lead to our inability to increase or maintain our prices, which could have a material adverse impact on our results of operations. The portable storage and mobile office industries are highly competitive and highly fragmented. Many of the markets in which we operate are served by numerous competitors, ranging from national companies like ourselves, to smaller multi-regional companies and small, independent businesses with a limited number of locations. See “Business — Competition.” Some of our principal competitors are less leveraged than we are and have lower fixed costs and may be better able to withstand adverse market conditions within the industry. Additionally, some of our competitors currently offer products outside of our core container offerings but may have better brand recognition in their current end customer segments. If these competitors use their brand awareness to enter our product offerings, customers may choose these competitors’ products over ours and we could lose business. We generally compete on the basis of, among other things, quality and breadth of service, expertise, reliability, and the price, size, and attractiveness of our rental units. Our competitors are competing aggressively on the basis of pricing and may continue to drive prices further down. To the extent that we choose to match our competitors’ declining prices, it could harm our results of operations. To the extent that we choose not to match or remain within a reasonable competitive distance from our competitors’ pricing, it could also harm our results of operations, as we may lose rental volume. We operate with a high amount of debt and we may incur significant additional indebtedness. Our operations are capital intensive, and we operate with a high amount of debt relative to our size. At December 31, 2010, we had the following outstanding issuances of senior notes (i) $150.0 million in aggregate principal amount of 6.875% senior notes due 2015; (ii) $200.0 million in aggregate principal amount of 7.785% senior notes due 2020; and (iii) $22.3 million of outstanding notes under a previous issuance of $200.0 million in aggregate principal amount of 9.75% senior notes due 2014, which were originally issued by MSG and assumed by us in connection with our acquisition of MSG in June 2008. In January 2011, the remaining outstanding amount of the 9.75% senior notes due 2014 was redeemed and ceased to be outstanding. Additionally, we have entered into an ABL Credit Agreement under which we may borrow up to $850.0 million on a revolving loan basis, which means that amounts repaid may be reborrowed. All amounts outstanding under the ABL Credit Agreement are due on June 27, 2013. At December 31, 2010, we had approximately $771.4 million of indebtedness. Our substantial indebtedness could have adverse consequences. For example, it could: (cid:129) require us to dedicate a substantial portion of our cash flow from operations to payments on our indebt- edness, which could reduce the availability of our cash flow to fund future working capital, capital expenditures, acquisitions and other general corporate purposes; (cid:129) make it more difficult for us to satisfy our obligations with respect to our senior notes; (cid:129) expose us to the risk of increased interest rates, as certain of our borrowings will be at variable rates of interest; (cid:129) require us to sell assets to reduce indebtedness or influence our decisions about whether to do so; (cid:129) increase our vulnerability to general adverse economic and industry conditions; (cid:129) limit our flexibility in planning for, or reacting to, changes in our business and our industry; (cid:129) restrict us from making strategic acquisitions or pursuing business opportunities; and (cid:129) limit, along with the financial and other restrictive covenants in our indebtedness, among other things, our ability to borrow additional funds. Failing to comply with those covenants could result in an event of default which, if not cured or waived, could have a material adverse effect on our business, financial condition and results of operations. 18 Covenants in our debt instruments restrict or prohibit our ability to engage in or enter into a variety of transactions. The indentures governing our 6.875% senior notes and 7.785% senior notes, contain various covenants that limit our discretion in operating our business. In particular, we are limited in our ability to merge, consolidate or transfer substantially all of our assets, issue preferred stock of subsidiaries and create liens on our assets to secure debt. In addition, if there is default, and we do not maintain borrowing availability in excess of certain pre- determined levels, we may be unable to incur additional indebtedness, make restricted payments (including paying cash dividends on our capital stock) and redeem or repurchase our capital stock. Our senior notes do not contain financial maintenance covenants and the financial maintenance covenants under our revolving credit facility are not applicable unless we fall below $100 million in borrowing availability. Our revolving credit facility requires us, under certain limited circumstances, to maintain certain financial ratios and limits our ability to make capital expenditures. These covenants and ratios could have an adverse effect on our business by limiting our ability to take advantage of financing, merger and acquisition or other corporate opportunities and to fund our operations. Breach of a covenant in our debt instruments could cause acceleration of a significant portion of our outstanding indebtedness. Any future debt could also contain financial and other covenants more restrictive than those imposed under the indentures governing the senior notes, and the revolving credit facility. A breach of a covenant or other provision in any debt instrument governing our current or future indebtedness could result in a default under that instrument and, due to cross-default and cross-acceleration provisions, could result in a default under our other debt instruments. Upon the occurrence of an event of default under the revolving credit facility or any other debt instrument, the lenders could elect to declare all amounts outstanding to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders could proceed against the collateral granted to them, if any, to secure the indebtedness. If the lenders under our current or future indebtedness accelerate the payment of the indebtedness, we cannot assure you that our assets or cash flow would be sufficient to repay in full our outstanding indebtedness, including the senior notes. The amount we can borrow under our revolving credit facility depends in part on the value of the portable storage units in our lease fleet. If the value of our lease fleet declines under appraisals our lenders receive, the amount we can borrow will similarly decline. We are required to satisfy several covenants with our lenders that are affected by changes in the value of our lease fleet. We would be in breach of certain of these covenants if the value of our lease fleet drops below specified levels. If this happens, we may not be able to borrow the amounts we need to expand our business, and we may be forced to liquidate a portion of our existing fleet. Disruptions in our information technology systems (including our phone system) could limit our ability to effectively operate, monitor and control our operations and adversely affect our operating results. Our information technology systems facilitate our ability to monitor and control our operations and adjust to changing market conditions. We rely on a sophisticated phone and data network to communicate with customers and within our branch system. Any disruptions in these systems or the failure of these systems to operate as expected could, depending on the magnitude of the problem, materially adversely affect our financial condition or operating results by limiting our capacity to effectively monitor and control our operations and adjust to changing market conditions in a timely manner. Like other companies, our information technology systems may be vulnerable to a variety of interruptions due to events beyond our control, including, but not limited to, natural disasters, terrorist attacks, telecommunications failures, computer viruses, hackers, and other security issues. In addition, because our systems contain information about individuals and businesses, our failure to maintain the security of the data we hold, whether the result of our own error or the malfeasance or errors of others, could harm our reputation or give rise to legal liabilities leading to lower revenues, increased costs and other potential material adverse effects on our results of operations. 19 As Department of Transportation regulations increase, our operations could be negatively impacted and competition for qualified drivers could increase and result in increased labor costs. We operate in the United States pursuant to operating authority granted by the U.S. Department of Trans- portation, or DOT. Our company drivers also must comply with the safety and fitness regulations of the DOT, including those relating to drug and alcohol testing and hours-of-service. Such matters as weight and equipment dimensions also are subject to government regulations. We also may become subject to new or more restrictive regulations relating to fuel emissions, drivers’ hours-of-service, ergonomics, on-board reporting of operations, collective bargaining, security at ports, and other matters affecting safety or operating methods. The DOT is currently engaged in a rulemaking proceeding regarding drivers’ hours-of-service, and the result could negatively impact utilization of our equipment. For example, in December 2010, CSA 2010, a new enforcement and compliance model implementing driver standards in addition to our current standards, was launched. CSA 2010 may reduce the number of eligible drivers and/or negatively impact our fleet ranking. Under CSA 2010, drivers and fleets will be evaluated and ranked based on certain safety-related standards. The methodology for determining a carrier’s DOT safety rating will be expanded to include the on-road safety performance of the carrier’s drivers. As a result, certain current and potential drivers may no longer be eligible to drive for us, our fleet could be ranked poorly as compared to our peer firms, and our safety rating could be adversely impacted. A reduction in eligible drivers or a poor fleet ranking may result in difficulty attracting and retaining qualified drivers, which could result in increased compensation costs. We may not be able to generate sufficient cash to service all of our debt, and may be forced to take other actions to satisfy our obligations under such indebtedness, which may not be successful. Our ability to make scheduled payments on or to refinance our obligations under, our debt will depend on our financial and operating performance and that of our subsidiaries, which, in turn, will be subject to prevailing economic and competitive conditions and to the financial and business factors, many of which may be beyond our control. See the table under “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Contractual Obligations” for disclosure regarding the amount of cash required to service our debt. We may not maintain a level of cash flow from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness. If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek to obtain additional equity capital or restructure our debt. In the future, our cash flow and capital resources may not be sufficient for payments of interest on and principal of our debt, and such alternative measures may not be successful and may not enable us to meet our scheduled debt service obligations. We may not be able to refinance any of our indebtedness or obtain additional financing, particularly because of our anticipated high levels of debt and the debt incurrence restrictions imposed by the agreements governing our debt, as well as prevailing market conditions. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. The instruments governing our indebtedness restrict our ability to dispose of assets and use the proceeds from any such dispositions. We may not be able to consummate those sales, or if we do, at an opportune time, or the proceeds that we realize may not be adequate to meet debt service obligations when due. The market price of our common stock has been volatile and may continue to be volatile and the value of your investment may decline. The market price of our common stock has been volatile and may continue to be volatile. This volatility may cause wide fluctuations in the price of our common stock on The NASDAQ Global Select Market. The market price of our common stock is likely to be affected by: (cid:129) changes in general conditions in the economy, geopolitical events or the financial markets; (cid:129) variations in our quarterly operating results; 20 (cid:129) changes in financial estimates by securities analysts; (cid:129) other developments affecting us, our industry, customers or competitors; (cid:129) changes in demand for our products or the prices we charge due to changes in economic conditions, competition or other factors; (cid:129) general economic conditions in the markets where we operate; (cid:129) the cyclical nature of our customers’ businesses, particularly those operating in the construction sectors; (cid:129) rental rate changes in response to competitive factors; (cid:129) bankruptcy or insolvency of our customers, thereby reducing demand for our used units; (cid:129) seasonal rental patterns, with rental activity tending to be lowest in the first quarter of the year; (cid:129) timing of acquisitions of companies and new location openings and related costs; (cid:129) labor shortages, work stoppages or other labor difficulties; (cid:129) possible unrecorded liabilities of acquired companies; (cid:129) possible write-offs or exceptional charges due to changes in applicable accounting standards, goodwill impairment, or impairment of assets; (cid:129) the operating and stock price performance of companies that investors deem comparable to us; and (cid:129) the number of shares available for resale in the public markets under applicable securities laws. Unionization by some or all of our employees could cause increases in operating costs. None of our employees are presently covered by collective bargaining agreements. However, from time to time various unions have attempted to organize some of our employees. We cannot predict the outcome of any continuing or future efforts to organize our employees, the terms of any future labor agreements, or the effect, if any, those agreements might have on our operations or financial performance. We believe that a unionized workforce would generally increase our operating costs, divert the attention of management from servicing customers and increase the risk of work stoppages, all of which could have a material adverse effect on our business, results of operations or financial condition. Fluctuations between the British pound and U.S. dollar could adversely affect our results of operations. We derived approximately 15.6% of our total revenues in 2010 from our operations in the U.K. The financial position and results of operations of our U.K. subsidiaries are measured using the British pound as the functional currency. As a result, we are exposed to currency fluctuations both in receiving cash from our U.K. operations and in translating our financial results back into U.S. dollars. We believe the impact on us of currency fluctuations from an operations perspective is mitigated by the fact that the majority of our expenses, capital expenditures and revenues in the U.K. are in British pounds. We do, however, have significant currency exposure as a result of translating our financial results from British pounds into U.S. dollars for purposes of financial reporting. Assets and liabilities of our U.K. subsidiary are translated at the period end exchange rate in effect at each balance sheet date. Our income statement accounts are translated at the average rate of exchange prevailing during each month. Translation adjustments arising from differences in exchange rates from period to period are included in the accumulated other comprehensive income (loss) in stockholders’ equity. A strengthening of the U.S. dollar against the British pound reduces the amount of income or loss we recognize on a consolidated basis from our U.K. business. We cannot predict the effects of further exchange rate fluctuations on our future operating results. We are also exposed to additional currency transaction risk when our U.S. operations incur purchase obligations in a currency other than in U.S. dollars and our U.K. operations incur purchase obligations in a currency other than in British pounds. As exchange rates vary, our results of operations and profitability may be harmed. We do not currently hedge our currency transaction or translation exposure, nor do we have any current plans to do so. The risks we face in foreign currency transactions and translation may continue to increase as we further develop and expand our U.K. 21 operations. Furthermore, to the extent we expand our business into other countries, we anticipate we will face similar market risks related to foreign currency translation caused by exchange rate fluctuations between the U.S. dollar and the currencies of those countries. If we determine that our goodwill has become impaired, we may incur significant charges to our pre-tax income. At December 31, 2010, we had $511.4 million of goodwill on our Consolidated Balance Sheet. Goodwill represents the excess of cost over the fair value of net assets acquired in business combinations. In the future, goodwill and intangible assets may increase as a result of future acquisitions. Goodwill and intangible assets are reviewed at least annually for impairment. Impairment may result from, among other things, deterioration in the performance of acquired businesses, adverse market conditions, stock price, and adverse changes in applicable laws or regulations, including changes that restrict the activities of the acquired business. For more information, see the Notes to Consolidated Financial Statements included in our financial statements contained in this Annual Report. We are subject to environmental regulations and could incur costs relating to environmental matters. We are subject to various federal, state, and local environmental protection and health and safety laws and regulations governing, among other things: (cid:129) the emission and discharge of hazardous materials into the ground, air, or water; (cid:129) the exposure to hazardous materials; and (cid:129) the generation, handling, storage, use, treatment, identification, transportation, and disposal of industrial by- products, waste water, storm water, oil/fuel and other hazardous materials. We are also required to obtain environmental permits from governmental authorities for certain of our operations. If we violate or fail to obtain or comply with these laws, regulations, or permits, we could be fined or otherwise sanctioned by regulators. We could also become liable if employees or other parties are improperly exposed to hazardous materials. Under certain environmental laws, we could be held responsible for all of the costs relating to any contam- ination at, or migration to or from, our or our predecessors’ past or present facilities. These laws often impose liability even if the owner, operator or lessor did not know of, or was not responsible for, the release of such hazardous substances. Environmental laws are complex, change frequently, and have tended to become more stringent over time. The costs of complying with current and future environmental and health and safety laws, and our liabilities arising from past or future releases of, or exposure to, hazardous substances, may adversely affect our business, results of operations, or financial condition. The supply and cost of used ISO containers fluctuates, which can affect our pricing and our ability to grow. As needed, we purchase, remanufacture and modify used ISO containers in order to expand our lease fleet. If used ISO container prices increase substantially, we may not be able to manufacture enough new units to grow our fleet. These price increases also could increase our expenses and reduce our earnings, particularly if we are not able (due to competitive reasons or otherwise) to raise our rental rates to absorb this increased cost. Conversely, an oversupply of used ISO containers may cause container prices to fall. In such event, competitors may then lower the lease rates on their storage units. As a result, we may need to lower our lease rates to remain competitive. These events would cause our revenues and our earnings to decline. 22 The supply and cost of raw materials we use in manufacturing fluctuates and could increase our operating costs. As needed, we manufacture portable storage units to add to our lease fleet and for sale. In our manufacturing process, we purchase steel, vinyl, wood, glass and other raw materials from various suppliers. We cannot be sure that an adequate supply of these materials will continue to be available on terms acceptable to us. The raw materials we use are subject to price fluctuations that we cannot control. Changes in the cost of raw materials can have a significant effect on our operations and earnings. Rapid increases in raw material prices are often difficult to pass through to customers, particularly to leasing customers. If we are unable to pass on these higher costs, our profitability could decline. If raw material prices decline significantly, we may have to write down our raw materials inventory values. If this happens, our results of operations and financial condition will decline. Some zoning laws in the U.S. and Canada and temporary planning permission regulations in Europe restrict the use of our portable storage and office units and therefore limit our ability to offer our products in all markets. Most of our customers use our storage units to store their goods on their own properties. Local zoning laws and temporary planning permission regulations in some of our markets do not allow some of our customers to keep portable storage and office units on their properties or do not permit portable storage units unless located out of sight from the street. If local zoning laws or planning permission regulations in one or more of our markets no longer allow our units to be stored on customers’ sites, our business in that market will suffer. If we fail to retain key management and personnel, we may be unable to implement our business plan. One of the most important factors in our ability to profitably execute our business plan is our ability to attract, develop and retain qualified personnel, including our CEO and operational management. Our success in attracting and retaining qualified people is dependent on the resources available in individual geographic areas and the impact on the labor supply due to general economic conditions, as well as our ability to provide a competitive compensation package, including the implementation of adequate drivers of retention and rewards based on performance, and work environment. The departure of any key personnel and our inability to enforce non-competition agreements could have a negative impact on our business. We may not be able to successfully acquire new operations or integrate future acquisitions, which could cause our business to suffer. We may not be able to successfully complete potential strategic acquisitions if we cannot reach agreement on acceptable terms or for other reasons. If we buy a company, we may experience difficulty integrating that Company’s personnel and operations, which could negatively affect our operating results. In addition: (cid:129) the key personnel of the acquired company may decide not to work for us; (cid:129) we may experience business disruptions as a result of information technology systems conversions; (cid:129) we may experience additional financial and accounting challenges and complexities in areas such as tax planning, treasury management, and financial reporting; (cid:129) we may be held liable for environmental risks and liabilities as a result of our acquisitions, some of which we may not have discovered during our due diligence; (cid:129) our ongoing business may be disrupted or receive insufficient management attention; and (cid:129) we may not be able to realize the cost savings or other financial benefits we anticipated. In connection with future acquisitions, we may assume the liabilities of the companies we acquire. These liabilities, including liabilities for environmental-related costs, could materially and adversely affect our business. We may have to incur debt or issue equity securities to pay for any future acquisition, the issuance of which could involve the imposition of restrictive covenants or be dilutive to our existing stockholders. 23 If we do not manage new markets effectively, some of our new branches and acquisitions may lose money or fail, and we may have to close unprofitable locations. Closing a branch in such circumstances would likely result in additional expenses that would cause our operating results to suffer. In connection with expansion outside of the U.S., we face fluctuations in currency exchange rates, exposure to additional regulatory requirements, including certain trade barriers, changes in political and economic conditions, and exposure to additional and potentially adverse tax regimes. Our success in Europe depends, in part, on our ability to anticipate and effectively manage these and other risks. Our failure to manage these risks may adversely affect our growth, in Europe and elsewhere, and lead to increased administrative costs. We are exposed to various possible claims relating to our business and our insurance may not fully protect us. We are exposed to various possible claims relating to our business. These possible claims include those relating to (1) personal injury or death caused by containers, offices or trailers rented or sold by us, (2) motor vehicle accidents involving our vehicles and our employees, (3) employment-related claims, (4) property damage, and (5) commercial claims. Our insurance policies have deductibles or self-insured retentions which would require us to expend amounts prior to taking advantage of coverage limits. Currently, we believe that we have adequate insurance coverage for the protection of our assets and operations. However, our insurance may not fully protect us for certain types of claims, such as claims for punitive damages or for damages arising from intentional misconduct, which are often alleged in third party lawsuits. In addition, we may be exposed to uninsured liability at levels in excess of our policy limits. If we are found liable for any significant claims that are not covered by insurance, our liquidity and operating results could be materially adversely affected. It is possible that our insurance carrier may disclaim coverage for any class action and derivative lawsuits against us. It is also possible that some or all of the insurance that is currently available to us will not be available in the future on economically reasonable terms or not available at all. In addition, whether we are covered by insurance or not, certain claims may have the potential for negative publicity surrounding such claims, which may lead to lower revenues, as well as additional similar claims being filed. We may not be able to adequately protect our intellectual property and other proprietary rights that are material to our business. Our ability to compete effectively depends in part upon protection of our rights in trademarks, copyrights and other intellectual property rights we own or license, including patents to our locking system. Our use of contractual provisions, confidentiality procedures and agreements, and trademark, copyright, unfair competition, trade secret and other laws to protect our intellectual property and other proprietary rights may not be adequate. Litigation may be necessary to enforce our intellectual property rights and protect our proprietary information and patents, or to defend against claims by third parties that our services or our use of intellectual property infringe their intellectual property rights. Any litigation or claims brought by or against us could result in substantial costs and diversion of our resources. A successful claim of trademark, copyright or other intellectual property infringement against us could prevent us from providing services, which could harm our business, financial condition or results of operations. In addition, a breakdown in our internal policies and procedures may lead to an unintentional disclosure of our proprietary, confidential or material non-public information, which could in turn harm our business, financial condition or results of operations. ITEM 1B. UNRESOLVED STAFF COMMENTS. We have received no written comments regarding our periodic or current reports from the staff of the SEC that were issued 180 days or more preceding the end of our 2010 fiscal year and that remain unresolved. 24 ITEM 2. PROPERTIES. We own several properties in the U.S., including our facility in Maricopa, Arizona, approximately 30 miles south of Phoenix. In the U.K., we own two locations. We lease all of our other locations. All of our major leased properties have remaining lease terms of between 1 and 15 years and we believe that satisfactory alternative properties can be found in all of our markets if we do not renew these existing leased properties. The properties we lease for our branch locations are generally located in industrial areas so that we can stack containers, store large amounts of containers and offices and operate our delivery trucks. These properties tend to be 1 to 16 acre sites with little development needed for us to use them, other than a paved or hard-packed surface, utilities and proper zoning. Four of our leased properties are with related persons and the terms of these related persons lease agreements have been reviewed and approved by the independent directors who comprise a majority of the members of our Board of Directors. Our Maricopa facility is on approximately 43 acres. The facility housed our manufacturing, assembly, restoring, painting and vehicle maintenance operations. At the end of 2008, we restructured our manufacturing operations, and as a result, this facility for the near future will be primarily used to rebrand, remanufacture and do repairs and maintenance on our existing lease fleet and to store any excess units in our fleet. We lease our corporate and administrative offices in Tempe, Arizona. These offices occupy approximately 55,000 square feet of office space, including our NSC. The lease term expires in December 2014. Our European headquarters is located in Stockton-on-Tees, United Kingdom where we lease approximately 10,000 square feet of office space. The term of this lease expires in July 2017. ITEM 3. LEGAL PROCEEDINGS. We are party from time to time to various claims and lawsuits that arise in the ordinary course of business, including claims related to employment matters, contractual disputes, personal injuries and property damage. In addition, various legal actions, claims and governmental inquiries and proceedings are pending or may be instituted or asserted in the future against us and our subsidiaries. Litigation is subject to many uncertainties, and the outcome of the individual litigated matters is not predictable with assurance. It is possible that certain of the actions, claims, inquiries or proceedings, including those discussed above, could be decided unfavorably to us or any of our subsidiaries involved. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, we do not believe that the ultimate resolution of these claims or lawsuits will have a material adverse effect on our business, financial condition, results of operations or cash flows. 25 ITEM 4.

We have not paid cash dividends on our common stock and do not expect to do so in the foreseeable future, as we intend to retain all earnings to provide funds for the operation and expansion of our business. Further, our revolving credit agreement restricts our ability to pay dividends or other distributions on our common stock. Sales of Unregistered Securities; Repurchases of Securities On June 27, 2008, as part of the consideration for the acquisition of Mobile Storage Group, we issued 8.6 million shares of our Series A Convertible Redeemable Participating Preferred Stock to the former stockholders of Mobile Storage Group. This issuance was made pursuant to an exemption from registration under Regulation D of the Securities Act of 1933, as amended. These outstanding shares of preferred stock are convertible into an aggregate of 8.2 million shares of our common stock at any time at the option of the holders, representing an initial conversion price of $18.00 per common share. The preferred stock will be mandatorily convertible into our common stock if, after the first anniversary of the issuance thereof, our common stock trades above $23.00 per share for a period of 30 consecutive days.

We present EBITDA because we believe it provides useful information regarding our ability to meet our future debt payment requirements, capital expenditures and working capital requirements and that it provides an overall evaluation of our financial condition. In addition, EBITDA is a component of certain financial covenants under our revolving credit facility and is used to determine our available borrowing capacity and the facility’s applicable interest rate in effect at the end of each measurement period. EBITDA has certain limitations as an analytical tool and should not be used as a substitute for net income, cash flows, or other consolidated income or cash flow data prepared in accordance with generally accepted accounting principles in the U.S. or as a measure of our profitability or our liquidity. In particular, EBITDA, as defined does not include: (cid:129) Interest expense — because we borrow money to partially finance our capital expenditures, primarily related to the expansion of our lease fleet, interest expense is a necessary element of our cost to secure this financing to continue generating additional revenues. (cid:129) Income taxes — because we operate in jurisdictions subject to income taxation, income tax expense is a necessary element of our costs to operate. (cid:129) Depreciation and amortization — because we are a leasing company, our business is very capital intensive and we hold acquired assets for a period of time before they generate revenues, cash flow and earnings; therefore, depreciation and amortization expense is a necessary element of our business. (cid:129) Debt restructuring or extinguishment expense — debt restructuring and extinguishment expenses are not deducted in our various calculations made under our credit agreements and are treated no differently than interest expense. As discussed above, interest expense is a necessary element of our cost to finance a portion of the capital expenditures needed for the growth of our business. When evaluating EBITDA as a performance measure, and excluding the above-noted charges, all of which have material limitations, investors should consider, among other factors, the following: (cid:129) increasing or decreasing trends in EBITDA; (cid:129) how EBITDA compares to levels of debt and interest expense; and (cid:129) whether EBITDA historically has remained at positive levels. Because EBITDA, as defined, excludes some but not all items that affect our cash flow from operating activities, EBITDA may not be comparable to a similarly titled performance measure presented by other companies. (2) Adjusted EBITDA represents EBITDA plus the sum of certain transactions that are excluded when internally evaluating our operating performance. Management believes adjusted EBITDA is a more meaningful eval- uation and comparison of our core business when comparing period over period results without regard to transactions that potentially distort the performance of our core business operating results. (3) EBITDA and adjusted EBITDA margins are calculated as EBITDA and adjusted EBITDA divided by total revenues expressed as a percentage. The GAAP financial measure that is most directly comparable to EBITDA margin is operating margin, which represents operating income divided by revenues. EBITDA margin is presented along with the operating margin in the selected financial data under “Operating Data” so as not to imply that more emphasis be placed on this measure than the corresponding GAAP measure. (4) Integration, merger and restructuring expenses represent costs we incurred in connection with the MSG acquisition and the expenses in connection with the continued restructuring of our manufacturing operations as a result of the MSG acquisition. (5) Goodwill impairment represents a non-cash charge for a portion of our goodwill relating to our United Kingdom and The Netherlands operations. (6) Class action settlement expense represents costs incurred and the estimated settlement cost of a purported class action lawsuit that was settled in order to avoid the uncertainties and cost of continued litigation representing $0.7 million and $0.1 million in 2009 and 2010, respectively and other represents one-time expenses. 30 ITEM 7. 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 the consolidated financial statements and the accompanying notes included elsewhere in this Annual Report. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in those forward-looking statements as a result of certain factors, including, but not limited to, those described under Item 1A, “Risk Factors”. The following discussion takes into consideration our acquisition of Mobile Storage Group, Inc. (MSG) on June 27, 2008. The operations of MSG are included in our operating results for only six months of the twelve months ended December 31, 2008. Additionally, in 2008, the results of operations include four other acquisitions (beyond MSG) we completed during 2008. There were no acquisitions consummated in either 2009 or 2010. Executive Summary Although fiscal 2010 was a challenging year for us globally with the prolonged weakened economy still impacting businesses and consumers, we were proactive on the cost side of our business and saw signs of positive growth in the last half of 2010. Despite our total revenue declining approximately 11.7% from the 2009 level, we continued to take essential actions to keep our business right-sized, primarily by further reducing payroll costs where possible and by other effective cost management measures allowing us to maintain a strong adjusted EBITDA margin of 39.3%. We were cash flow positive (excluding the MSG Merger) for the third consecutive year as we have continued to manage our operations and capital expenditures and have used this positive cash flow to pay down debt of approximately $160.0 million since June 30, 2008. We began to see signs of recovery beginning in the second quarter and we also continued to enact selective price increases focusing on customers that had units out on rent for an extended period of time and to date, have observed no measurable difference in the attrition rates for these customers. By the fourth quarter of 2010, our level of business had finally ceased to decline on a year over year basis. We continue to invest in our business with the adoption of a hybrid sales model incorporating a local as well as centralized component, with both groups incentivized on the basis of performance. The salespeople at the branches primarily focus on construction customers who tend to be large multi-unit customers that benefit from local service, while those in our NSC in Tempe, Arizona are targeting the balance of our customers who are generally single unit customers. We also implemented a similar program in Europe in 2010. In late 2008, we restructured our manufacturing operations to reduce costs and implemented two rounds of company-wide reductions in addition to other headcount reductions, which together resulted in cost savings that continued throughout 2010. We continue to monitor activity levels through a variety of metrics we use to determine the optimal efficiencies for our drivers, dispatchers, managers, salespeople and corporate staff needed in the changing business environment without negatively impacting customer service and sales activity levels. In 2009, we identified certain branch operations that we converted to operational yards, which operate at a significantly lower cost structure than traditional branches, and in 2010, we opened three new greenfield locations as operational yards to redeploy fleet and increase revenue while maintaining that same level of efficiency. We monitor the effectiveness of our branches and where possible, we will continue to migrate some of our branches to these lower cost operational yards in the future. In August 2010, we amended our revolving credit facility to reduce the line by $50.0 million to $850.0 million, which reduces our ongoing unused line fees. This amendment also allows a permitted refinancing of our senior notes as well as restricted payments and acquisitions to occur without financial covenant restrictions provided we have $250.0 million in pro forma excess borrowing availability. Following this amendment, in November 2010 we completed an offering of $200.0 million principal amount of 7.875% senior notes due 2020 and redeemed $170.6 million principal amount of 9.75% senior notes due 2014. We redeemed the balance of the 9.75% senior notes due 2014 ($22.3 million) in January 2011. Our senior notes do not contain financial maintenance covenants and the financial maintenance covenants under our revolving credit facility are not applicable unless we fall below $100.0 million in borrowing availability. 31 We believe these continued efforts, coupled with managing working capital and controls over capital expenditures will allow us to generate free cash flow in 2011 and to continue paying down debt, which remains a top management priority. We have reduced borrowings under our asset based revolving credit facility from $473.7 million at December 31, 2009 to $396.9 million at December 31, 2010, leaving us with $385.9 million of unused borrowing capacity under our facility. As we continue to seek alternative methods to reduce expenses we are at the same time focusing on sales growth to our core customers and continue our sophisticated sales campaign strategies at our NSC and branches. We accomplish this in part through increasing salesperson accountability through our disciplined sales processes which we believe has traditionally given us a significant competitive advantage. General We are the world’s leading provider of portable storage solutions, through a total lease fleet of approximately 245,500 units at December 31, 2010. We offer a wide range of portable storage products in varying lengths and widths with an assortment of differentiated features such as our patented locking systems, multiple doors, electrical wiring and shelving. We derive most of our revenues from leasing of portable storage containers, security offices and mobile offices. In addition to our leasing business, we also sell portable storage containers and occasionally sell security and mobile office units. We also sell non-core assets, in particular van trailers and timber units, when the opportunity arises. Our sales revenues represented 10.0% of total revenues in 2010. On June 27, 2008, we acquired the outstanding shares of MSG and MSG became a wholly-owned subsidiary of Mobile Mini. We refer to this transaction as “the Merger” or “the MSG acquisition” throughout this Annual Report. The MSG acquisition was the largest acquisition we have completed and it increased the scope of our operations in both the U.S. and the U.K. Our consolidated statements of income for the periods reported include certain estimated expenses expected or incurred related to integration of the business acquired in the MSG acquisition and restructuring charges related to restructuring of our manufacturing operations as a result of the MSG acquisition. Prior to acquiring MSG, we grew both organically and through smaller acquisitions, which we used to gain a presence in new markets. Traditionally, we enter new markets through the acquisition of the business of a smaller local competitor and then implement our business model, which is usually more focused on customer service and marketing than the acquired business or other market competitors. Given our current utilization levels, we are currently entering new markets through greenfield locations by migrating idle fleet to new low-cost operational yards. These greenfield operational yards do not have all the overhead associated with a fully staffed branch as they typically only have drivers and yard personnel to handle deliveries and pick-ups of our fleet. A new location will generally have fairly low operating margins during its early years, but as our marketing efforts help us penetrate the new market and we increase the number of units on rent at the new location, we are typically able to reach company average levels of profitability after several years. The costs associated with opening a greenfield operational yard are lower than a fully staffed branch which should have a comparatively positive effect on margins. When we enter a new market, we incur certain costs in developing new infrastructure. For example, advertising and marketing costs will be incurred and certain minimum levels of staffing and delivery equipment will be put in place regardless of the new market’s revenue base. Once we have achieved revenues during any period that are sufficient to cover our fixed expenses, we are able to generate relatively high margins on incremental lease revenues. Therefore, each additional unit rented in excess of the break-even level contributes significantly to profitability. Conversely, any additional fixed expenses require us to achieve additional revenue in order to maintain our margins. When we refer to our operating leverage in this discussion, we are describing the impact on margins once we either cover our fixed costs or if we incur additional fixed costs. The level of non-residential construction activity is an important external factor that we examine to determine the direction of our business. Customers in the construction industry represented approximately 31% and 28% of our leased units at December 31, 2010 and December 31, 2009, respectively, and because of the degree of operating leverage we have, increases or decreases in non-residential construction activity can have a significant effect on our operating margins and net income. Beginning in the second quarter of 2008, the level of our construction related 32 business slowed down and then declined. The decline continued and adversely affected our results of operations. Although the construction business has not returned to pre-2009 levels, the level of our construction related business began to stabilize and then increase in 2010. In managing our business, we focus on growing leasing revenues, particularly in existing markets where we can take advantage of the operating leverage inherent in our business model. Our goals are to maintain a stable operating margin and, after the economy returns to normalized conditions, a steady growth rate in leasing revenues. We are a capital-intensive business, so in addition to focusing on earnings per share, we focus on adjusted EBITDA to measure our results. We calculate this number by first calculating EBITDA, which we define as net income before interest expense, debt restructuring or extinguishment expense, provision for income taxes, depreciation and amortization. This measure eliminates the effect of financing transactions that we enter into and it provides us with a means to track internally generated cash from which we can fund our interest expense and our lease fleet growth. In comparing EBITDA from year to year, we typically further adjust EBITDA to exclude the effect of what we consider transactions or events not related to our core business operations to arrive at what we define as adjusted EBITDA. For 2008, 2009 and 2010, adjusted EBITDA excludes the integration, merger and restructuring expenses related to the MSG acquisition, the reduction and restructuring of our manufacturing operations and other one-time expenses. In addition, 2008 excludes the impairment charge to goodwill. In managing our business, we measure our EBITDA margins from year to year based on the size of the branch. We define this margin as EBITDA divided by our total revenues, expressed as a percentage. We use this comparison, for example, to study internally the effect that increased costs have on our margins. As capital is invested in our established branch locations, we achieve higher EBITDA margins on that capital than we achieve on capital invested to establish a new branch, because our fixed costs are already in place in connection with the established branches. The fixed costs are those associated with yard and delivery equipment, as well as advertising, sales, marketing and office expenses. With a new branch or operational yard, we must first fund and absorb the start-up costs for setting up the new location, hiring and developing the management and sales team and developing our marketing and advertising programs. A new location will have lower EBITDA margins in its early years until the branch increases the number of units it has on rent. Because this operating leverage creates higher operating margins on incremental lease revenue, which we realize on a branch-by-branch basis when the branch achieves leasing revenues sufficient to cover the branch’s fixed costs, leasing revenues in excess of the break-even amount produce large increases in profitability. Conversely, absent growth in leasing revenues, the EBITDA margin at a branch will be expected to remain relatively flat on a period-by-period comparative basis if expenses remained the same or would decrease if fixed costs increased. Because EBITDA, adjusted EBITDA, EBITDA margin and adjusted EBITDA margin are non-GAAP financial measures, as defined by the SEC, we include in this Annual Report reconciliations of EBITDA to the most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the U.S. These reconciliations are included in Item 6, “Selected Financial Data”. Accounting and Operating Overview Our leasing revenues include all rent and ancillary revenues we receive for our portable storage, combination storage/office and mobile office units. Our sales revenues include sales of these units to customers. Our other revenues consist principally of charges for the delivery of the units we sell. Our principal operating expenses are: (1) cost of sales; (2) leasing, selling and general expenses; and (3) depreciation and amortization, primarily depreciation of the portable storage units and mobile offices in our lease fleet. Cost of sales is the cost of the units that we sold during the reported period and includes both our cost to buy, transport, remanufacture and modify used ISO containers and our cost to manufacture portable storage units and other structures. Leasing, selling and general expenses include among other expenses, advertising and other marketing expenses, real property lease expenses, commissions, repair and maintenance costs of our lease fleet and transportation equipment, stock-based compen- sation expense and corporate expenses for both our leasing and sales activities. Annual repair and maintenance expenses on our leased units over the last three years have averaged approximately 2.7% of lease revenues and are included in leasing, selling and general expenses. We expense our normal repair and maintenance costs as incurred (including the cost of periodically repainting units). 33 Our principal asset is our lease fleet, which has historically maintained value close to its original cost. The steel units in our lease fleet (other than van trailers) are depreciated on the straight-line method using an estimated useful life of 30 years, after the date the unit is placed in service, with an estimated residual value of 55%. The depreciation policy is supported by our historical lease fleet data, which shows that we have been able to obtain comparable rental rates and sales prices irrespective of the age of our container lease fleet. Our wood mobile office units are depreciated over 20 years to 50% of original cost. Van trailers, which constitute a small part of our fleet, are depreciated over 7 years to a 20% residual value. Van trailers, which are only added to the fleet as a result of acquisitions of portable storage businesses, are of much lower quality than storage containers and consequently depreciate more rapidly. We also have other non-core products that are added to our fleet as a result of acquisitions that have various other measures of useful lives and residual values. See “Item 1. Business — Product Lives and Durability”. During the last five fiscal years, our annual utilization levels averaged 67.3% and ranged from a low of 53.4% in 2010 to a high of 82.7% in 2006. The average lease fleet utilization was 53.4% and 59.2% for 2010 and 2009, respectively. Historically, our average utilization has been somewhat seasonal with the low normally being realized in the first quarter and the high realized in the fourth quarter of each year.

Leasing, our primary revenue focus, accounted for approximately 89.2% of total revenues during 2010. Leasing revenues in 2010 decreased $38.5 million, or 11.5%, to $295.0 million from $333.5 million in 2009. This decrease in leasing revenues resulted from a 14.4% decrease in the average number of units on lease, partially offset by a 3.4% increase in yield. Yield was primarily driven by higher trucking and ancillary revenues, while the average rental rate per unit remained virtually unchanged. In 2010, decline in both leasing and sales revenues was primarily the result of a reduction in business activity including non-residential construction activity and the weakness in the global economy. Our leasing revenue decline in 2010 over the same period in the prior year was 21.6%, 13.6%, 7.9% and 1.5% for the first, second, third and fourth quarters, respectively, as the year over year decline in our business leveled off by the time the year ended. Our revenues from the sale of units decreased $5.4 million, or 14.1%, to $33.2 million in 2010 from $38.6 million in 2009. Other revenues are primarily related to transportation charges for the delivery of units sold and the sale of ancillary products and represented 0.8% and 0.6% of total revenues in 2010 and 2009, respectively. Cost of sales relate to our sales revenue and as a percentage of sales revenue decreased slightly to 66.3% in 2010 from 66.8% in 2009. The gross profit margin on sales improved 0.5% in 2010 over 2009 levels. Leasing, selling and general expenses decreased $13.8 million, or 7.1%, to $179.1 million in 2010 from $192.9 million in 2009. Leasing, selling and general expenses, as a percentage of total revenues, were 54.2% and 51.5% in 2010 and 2009, respectively. This slight increase as a percentage of revenues is due to our fixed costs in a declining revenue environment and was partially offset by variable cost saving reductions achieved by the cost cutting measures we implemented in response to the reduced revenue levels, primarily payroll related reductions and migrating a number of our branches to operational yards. These operational yards do not have all the personnel and overhead expenses associated with a fully staffed branch. The major decreases in leasing, selling and general expenses for 2010 were (1) payroll and related payroll costs, which decreased by $9.2 million primarily due to reductions in our workforce and the decrease in commission expense resulting from the lower revenues levels; (2) insurance expense, which decreased $3.6 million due to improved safety programs and general reductions in premiums; and (3) advertising costs, which decreased $2.0 million as we moved further away from printed advertising campaigns. Delivery and freight costs, including fuel, increased $4.1 million, and were related to an increase in pick up and delivery activity of units by our drivers or third-party vendors, many which were wood modular offices that command higher delivery rates than regular containers. Repairs and maintenance expenses, increased $2.2 million, and includes the costs of repairing and maintaining our lease fleet as well as our delivery equipment, primarily our trucks, trailers and forklifts. Fixed costs for building and land leases for our locations, including real property taxes, increased $1.1 million, primarily due to contractual rate increases, lease renewals, additional acreage, new greenfield locations, and property tax increases. Integration, merger and restructuring expenses for 2010 were $4.0 million as compared to $11.3 million in 2009. These costs primarily represent costs related to reductions in our workforce. Adjusted EBITDA decreased $26.7 million, or 17.0%, to $129.9 million, as compared to $156.6 million for the same period in 2009 and adjusted EBITDA margins were 39.3% and 41.8% of total revenues for 2010 and 2009, respectively. The decrease is due to a decline in revenues, which were partially offset by our cost cutting measures. Depreciation and amortization expenses decreased $3.4 million, or 8.7%, to $35.7 million in 2010 from $39.1 million in 2009. The lower depreciation and amortization expense is primarily due to reduced amortization expense of intangible assets, primarily due to customer relationships that are amortized on an accelerated basis, and reduced depreciation expense related to property plant and equipment, primarily due to lower levels of that equipment. Depreciation expense includes the related depreciation on the additions to property, plant and equipment, primarily trucks, forklifts and trailers, to support the lease fleet, and the customized ERP, CRM and other software systems to enhance our reporting environment. It also includes wood modular offices which have a higher depreciation rate than our steel units. Depreciation and amortization expense also includes the amortization of customer relationships and trade name valuation that were associated with the Merger. Since December 31, 2009, our lease fleet cost basis for depreciation decreased $8.3 million. See “Critical Accounting Policies, Estimates and Judgments” within this Item 7. 35 Interest expense decreased $3.1 million, or 5.2%, to $56.4 million in 2010 from $59.5 million in 2009. The decrease in interest expense is attributable to a decrease in our lower average debt outstanding in 2010 compared to 2009, principally due to the use of operating cash flow to reduce our debt over the past year. Our average annual debt outstanding decreased $85.7 million, or 9.7%, compared to the same period last year. Additionally, we redeemed $6.0 million of our MSG Notes in the first quarter of 2010 and replaced $171.6 million of the 9.75% Notes with 7.875% Notes in the fourth quarter of 2010. Although we continue to reduce outstanding debt, the shift between our floating rate debt and our higher fixed interest rate debt has caused a slight increase in our weighted average interest rates as compared to the same period for 2009. The monthly weighted average interest rate on our debt was 6.5% for 2010 compared to 6.2% for 2009, excluding the amortizations of debt issuance and other costs. Taking into account the amortizations of debt issuance and other costs, the monthly weighted average interest rate was 7.1% in 2010 and 6.8% in 2009. Debt restructuring expense in 2010 of $11.0 million relates to the redemption of $170.6 million of our MSG Notes and represents the early tender offer and related consent premiums and the write-off of remaining unamortized acquisition date discount related to the notes redeemed. See “Liquidity and Capital Resources — Senior Notes”. Deferred financing costs write-off in 2010 of $0.5 million represents that portion of deferred financing costs associated with the $50.0 million Company elected reduction in the ABL Agreement. See “Liquidity and Capital Resources — Revolving Credit Facility”. Provision for income taxes was based on an annual effective tax rate of 38.5% for 2010 as compared to an annual effective tax rate of 39.4% for 2009. The 0.9% decrease is primarily due to a reduction in the U.K. corporate tax rate as well as the continued strengthening of our U.K. operations and their corresponding increased contribution to the consolidated net income. Our 2010 consolidated tax provision is based upon the expected tax rates for our operations in the U.S., Canada, U.K. and The Netherlands. At December 31, 2010, we had a federal net operating loss carryforward of approximately $301.6 million, which expires if unused from 2012 to 2030. In addition, we had net operating loss carryforwards in the various states in which we operate. We believe, based on internal projections, that we will generate sufficient taxable income needed to realize the corresponding federal and state deferred tax assets to the extent they are recorded as deferred tax assets in our balance sheet. Net income in 2010 was $13.5 million, as compared to $27.8 million in 2009. The 2010 year was negatively affected by expenses of $11.5 million ($7.1 million after tax), related to the redemption of the MSG Notes and the reduction in the ABL Agreement, both discussed above. In addition, the 2010 year was negatively affected by expenses of $4.0 million ($2.5 million after tax), related to integration, merger and restructuring. The 2009 year was negatively affected by expenses of $11.3 million ($7.0 million after tax), related to integration, merger and restructuring. Twelve Months Ended December 31, 2009 Compared to Twelve Months Ended December 31, 2008 Total revenues in 2009 decreased $40.9 million, or 9.9%, to $374.5 million from $415.4 million in 2008. Leasing, our primary revenue focus, accounted for approximately 89.1% of total revenues during 2009. Leasing revenues in 2009 decreased $38.0 million, or 10.2%, to $333.5 million from $371.5 million in 2008. This decrease in leasing revenues resulted from a 3.5% decrease in the average number of units on lease, and a 7.0% decrease in yield. Yield was primarily driven by lower ancillary revenues and the mix of the type of units on lease, while the average rental rate per unit remained virtually unchanged. In 2009, the decline in both leasing and sales revenues was primarily the result of a reduction in business activity level due to a continued decline in non-residential construction activity and the economic recession. Our leasing revenues declined in the last two quarters of 2009 from the 2008 levels. Leasing revenues increased in the first two quarters of 2009 because the comparable quarters in 2008 excluded the MSG merger. Our leasing revenue growth, or decline, rate in 2009 over the same period in the prior year was 27.8%, 15.9%, (31.2)% and (29.1)% for the first, second, third and fourth quarters, respectively. Our revenues from the sale of units decreased $2.7 million, or 6.5%, to $38.6 million in 2009 from $41.3 million in 2008. Other revenues are primarily related to transportation charges for the delivery of units sold and the sale of ancillary products and represented 0.6% of total revenues in both 2009 and 2008. 36 Cost of sales relate to our sales revenue and as a percentage of sales revenue decreased slightly to 66.8% in 2009 from 68.0% in 2008, thus the gross profit margin on sales improved 1.2% in 2009 over 2008 levels. Leasing, selling and general expenses decreased $19.4 million, or 9.2%, to $192.9 million in 2009 from $212.3 million in 2008. Leasing, selling and general expenses, as a percentage of total revenues, were 51.5% and 51.1% in 2009 and 2008, respectively. This slight increase as a percentage of revenues is due to a decline in leasing revenues, which were partially offset by the cost savings achieved in 2009. The $19.4 million decrease in 2009 is the result of cost synergies achieved in the MSG acquisition in addition to cost cutting measures on the reduced revenue levels. These cost cutting measures primarily involved reductions in our workforce and migrating a number of our branches to operational yards. These operational yards do not have all the personnel and overhead expenses associated with a fully staffed branch. The major decreases in leasing, selling and general expenses for 2009 were: (1) delivery and freight costs, including fuel, which decreased $9.5 million, and were related to the pick up and delivery of containers by our drivers or third-party vendors; (2) payroll and related payroll costs, which decreased by $8.6 million primarily in connection with reductions in our workforce; and (3) repairs and maintenance expenses, which decreased $7.2 million, and which includes the costs of repairing and maintaining our lease fleet as well as our trucks, trailers and forklifts. Fixed costs for building and land leases for our locations, including real property taxes, increased $4.2 million due to the assumption of leases utilized by the locations added in the Merger and contractual rate increases at many of these locations. Integration, merger and restructuring expenses for 2009 were $11.3 million as compared to $24.4 million in 2008. In 2009, these costs primarily represent costs related to reductions to our work force and the repositioning of fleet to their intended location. In 2008, these costs primarily represented estimated costs for exiting targeted Mobile Mini branch operations that overlapped with MSG’s properties, repositioning and relocating assets to their intended location and other costs associated with personnel and office expenses associated with the integration of the companies. Also included in the 2008 expense was our estimated cost for restructuring our manufacturing operations including severance, related benefit costs and asset impairment charges for the disposal of manufac- turing equipment and inventories that were not used in the restructured environment. Goodwill impairment in 2008 represented a non-cash charge for a portion of our goodwill related to our U.K. and The Netherlands operations. There was no goodwill impairment charges recorded in 2009. See Notes to Consolidated Financial Statements included in Item 8 in this report for a more detailed discussion. EBITDA increased $7.4 million, or 5.5%, to $144.4 million, as compared to $137.0 million for the same period in 2008 and EBITDA margins were 38.6% and 33.0% of total revenues for 2009 and 2008, respectively. Adjusted EBITDA was $156.6 million in 2009 as compared to $175.0 million in 2008 and adjusted EBITDA margins were 41.8% and 42.1% of total revenues for 2009 and 2008, respectively. Depreciation and amortization expenses increased $7.3 million, or 23.0%, to $39.1 million in 2009 from $31.8 million in 2008. The higher depreciation expense is primarily due to the depreciation of units acquired through prior years’ acquisitions. It also includes wood modular offices which have a higher depreciation rate than our steel units. Depreciation expense also includes the related depreciation on the additions to property, plant and equipment, primarily trucks, forklifts and trailers, to support the lease fleet, and the customized ERP, CRM and other software systems to enhance our reporting environment. Depreciation and amortization expense also includes the amortization of customer relationships and trade name valuation that were associated with the MSG Merger. Since December 31, 2008, our lease fleet cost basis for depreciation increased only by $1.1 million. See “Critical Accounting Policies, Estimates and Judgments” within this Item 7. Interest expense increased $11.4 million, or 23.6%, to $59.5 million in 2009 from $48.1 million in 2008. This increase is primarily due to the $540.9 million of debt we assumed in the Merger. Although at the time of the Merger, we assumed the MSG Notes and our interest rate spread under our revolving credit facility increased from LIBOR + 1.25% to LIBOR + 2.50%, our average borrowing rate declined slightly in 2009, due to lower prevailing LIBOR rates. The monthly weighted average interest rate on our debt was 6.2% for 2009 compared to 6.8% for 2008, excluding the amortizations of debt issuance and other costs. Taking into account the amortizations of debt issuance and other costs, the monthly weighted average interest rate was 6.8% in 2009 and 7.2% in 2008. 37 Provision for income taxes was based on an annual effective tax rate of 39.4% for 2009 as compared to an annual effective tax rate of 49.1% for 2008. Our 2008 effective tax rate was negatively affected by the goodwill impairment charge of $13.7 million related to our European operations, which was not tax deductible. Our 2009 consolidated tax provision includes the expected tax rates for our operations in the U.S., Canada, U.K. and The Netherlands. At December 31, 2009, we had a federal net operating loss carryforward of approximately $216.8 million, which expires if unused from 2017 to 2029. In addition, we had net operating loss carryforwards in the various states in which we operate. We believe, based on internal projections, that we will generate sufficient taxable income needed to realize the corresponding federal and state deferred tax assets to the extent they are recorded as deferred tax assets in our balance sheet. Net income in 2009 was $27.8 million, as compared to $29.0 million in 2008. Our 2009 net income results were primarily achieved by maintaining our operating margins. The 2009 year was negatively affected by expenses of $11.3 million ($7.0 million after tax), related to integration, merger and restructuring. The 2008 year was negatively affected by expenses of $24.4 million ($15.3 million after tax), related to integration, merger and restructuring in addition to a $13.7 million after tax charge for goodwill impairment. Liquidity and Capital Resources Liquidity Summary Leasing is a capital-intensive business that requires us to acquire assets before they generate revenues, cash flow and earnings. The assets which we lease have very long useful lives and require relatively little recurrent maintenance expenditures. Most of the capital we deploy into our leasing business historically has been used to expand our operations geographically, to increase the number of units available for lease at our leasing 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 our cash flow from operations and the deferral of income taxes caused by accelerated depreciation of our fixed assets in our tax return filings. For the past three years, we were cash flow positive (after capital expenditures but excluding the Merger). During the past three years, our capital expenditures and acquisitions have been funded from our operating cash flow, and from borrowings under our revolving credit facility. Our operating cash flow is generally weakest during the first quarter of each fiscal year, when customers who leased containers for holiday storage return the units and as a result of seasonal weather in some of our markets. During 2008, 2009 and 2010, we significantly reduced our capital expenditures and were able to fund capital expenditures with cash flow from operations. We expect this trend to continue in 2011. In addition to cash flow generated by operations, our principal current source of liquidity is our revolving credit facility described below. Senior Notes. At December 31, 2010, we had three series of outstanding senior notes (i) $150.0 million aggregate principal amount of 6.875% senior notes due 2015 (the 2015 Notes), (ii) $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the 2020 Notes, and together with the 2015 Notes, the Mobile Mini Notes) and (iii) $22.3 million aggregate principal amount of 9.750% senior notes originally issued in the amount of $200.0 million by MSG due 2014 (the MSG Notes and together with the Mobile Mini Notes, the Senior Notes). In January 2011, all of the remaining MSG Notes were redeemed and ceased to be outstanding. We issued the 2020 Notes on November 23, 2010 at an initial offering price of 100% of their face value. The net proceeds from the sale of the 2020 Notes were used to redeem approximately $170.6 million of the outstanding MSG Notes, to pay the redemption and tender offer premium (approximately $8.9 million) and accrued interest (approximately $5.2 million) on the MSG Notes, and to pay fees and expenses related to the offering. We used the remaining net proceeds of approximately $10.4 million to repay borrowings under our revolving credit facility. The Senior Notes include covenants, indemnities and events of default that are customary for indentures of this type, including restrictions on the incurrence of additional debt, sales of assets and payment of dividends. Management does not believe that the covenants in the Senior Notes limit our ability to pursue its intended business strategy or its future financing needs. We were in compliance with the covenants of the Senior Notes as of December 31, 2010. 38 Revolving Credit Facility. On June 27, 2008, we entered into a $900.0 million ABL Credit Agreement (the Credit Agreement) with Deutsche Bank AG New York Branch and the other lenders party thereto. In August 2010, we entered into a Second Amendment to the Credit Agreement that, among other things, allows a permitted refinancing of our senior notes and for restricted payments and acquisitions to occur without financial covenant restrictions, provided we have $250.0 million in pro forma excess borrowing availability as defined in the Credit Agreement. We also elected to reduce the Credit Agreement by $50.0 million to $850.0 million, which reduces our ongoing unused line fees. All amounts outstanding under the Credit Agreement are due on June 27, 2013. The obligations of Mobile Mini and our subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets. At December 31, 2010, we had approximately $396.9 million of borrowings outstanding and $385.9 million of additional borrowing availability under the Credit Agreement, based upon borrowing base calculations as of such date. We were in compliance with the terms of the Credit Agreement as of December 31, 2010. Amounts borrowed under the Credit Agreement and repaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement will 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 margins for each type of loan will range from 2.25% to 2.75% for LIBOR loans and 0.75% to 1.25% for base rate loans depending upon our debt ratio, as defined in the Agreement, at the measurement date. Based on our debt ratio at December 31, 2010, our applicable interest rate margins for LIBOR loans will be LIBOR plus 2.75% and prime plus 1.25% for base rate loans until the next measurement date which is the end of each fiscal quarter and becomes effective the month following management’s communication to their lenders. The Credit Agreement provides for U.K. borrowings, denominated in either Pounds Sterling or Euros, by the Company’s subsidiary Mobile Mini U.K. Limited, based upon a U.K. borrowing base and additionally supported by the U.S. and Canada borrowing base, if necessary. For U.S. borrowings, which are denominated in U.S. Dollars, the borrowing base is based upon a U.S. and Canada borrowing base. 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, eligible inventory (including containers held for sale, work-in-process and raw materials), machinery and equipment and real property, each multiplied by an applicable advance rate or limit. The Credit Agreement does contain certain financial maintenance covenants, but these maintenance covenants are not applicable unless we have less than $100.0 million in borrowing availability under the facility. The Credit Agreement also contains customary negative covenants applicable to us and our subsidiaries, including covenants that restrict their ability to, among other things, (i) make capital expenditures in excess of defined limits, (ii) allow certain liens to attach to us or our subsidiary assets, (iii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iv) incur additional indebtedness or engage in certain other types of financing transactions, and (v) make acquisitions or other investments. We believe our cash provided by operating activities will provide for our normal capital needs for the next 12 months. If not, we have sufficient borrowings available under our revolving credit facility 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 think that there is a likelihood that any of our lenders might not be able to honor its commitments under the Credit Agreement. Operating Activities. Our operations provided net cash flow of $60.8 million in 2010 as compared to $86.8 million in 2009 and $98.5 million in 2008. The $26.0 million decrease in 2010 over 2009 in cash provided by operating activities was primarily attributable to a decrease in net income, after giving effect to non-cash items and a decrease in working capital. In 2010, working capital was primarily affected by a decrease in accrued liabilities. This decrease reflects the continued reduction in certain liabilities associated with the Merger and the interest payment in connection with the $170.6 million redemption of the MSG Notes. In 2009, there were decreases in receivables, inventories and deposits and prepaid expenses which were partially offset by decreases in accounts payable and accrued liabilities. These decreases were primarily due to the weakened economy, our restructured manufacturing operations and reduction of certain liabilities associated with the Merger. In 2008, there were 39 decreases in both inventories and deposits and prepaid expenses providing positive cash flows, which were offset by decreases in accounts payable and accrued liabilities. These decreases were primarily a result of the Merger and the decrease in purchases of inventories due to the restructuring of our manufacturing operations in late 2008. Cash provided by operating activities is enhanced by the deferral of most income taxes due to the rapid tax depreciation rate of our assets and our federal and state net operating loss carryforwards. At December 31, 2010, we had a federal net operating loss carryforward of approximately $301.6 million and a net deferred tax liability of $165.6 million. Investing Activities. Net cash provided by investing activities was $5.4 million in 2010, compared to $3.0 million in 2009 and to net cash used of $97.9 million in 2008. In 2010 and 2009, we did not acquire any businesses, compared to cash payments for acquisitions of $33.3 million in 2008. Capital expenditures for our lease fleet, net of proceeds from sale of lease fleet units, provided net cash proceeds of $13.8 million in 2010 compared to net cash proceeds of $12.0 million in 2009 and net cash expenditures of $48.3 million in 2008. Our capital expenditures for our lease fleet decreased 29.8% in 2010 compared to 2009 as we required fewer units to be manufactured or remanufactured from prior acquisitions due to the continued economic slowdown. Proceeds from sale of lease fleet units decreased 13.8% as compared to 2009. Additions to the lease fleet primarily included remanufacturing of prior acquisition units and manufactured steel offices. During the past several years we have increased the customization of our fleet, enabling us to differentiate our product from our competitors’ product, and we have complimented our lease fleet by adding wood mobile offices. At the end of 2008, we restructured our manufacturing operations to right-size our manufacturing requirements considering the large lease fleet we acquired in the MSG transaction. As a result of the acquisition and the current economic conditions, we anticipate our near term investing activities will be primarily focused on remanufacturing units acquired in prior acquisitions to meet our lease fleet standards as these units are placed on-rent. Capital expenditures for property, plant and equipment, net of proceeds from any sale of property, plant and equipment, were $8.4 million in 2010, $9.0 million in 2009 and $16.4 million in 2008. Expenditures for property, plant and equipment in 2010 were primarily for technology and communication improvements, delivery equipment and improvements to our branch locations. The amount of cash that we use during any period in investing activities is almost entirely within management’s discretion. We have no contracts or other arrangements pursuant to which we are required to purchase a fixed or minimum amount of goods or services in connection with any portion of our business. Maintenance capital expenditures is the cost to replace old forklifts, trucks and trailers that we use to move and deliver our products to our customers, and for enhancements to our computer information and communication systems. Our maintenance capital expenditures were approximately $2.2 million in 2010, $0.1 million in 2009 and $3.0 million in 2008. Financing Activities. Net cash used in financing activities was $67.7 million in 2010 as compared to $83.0 million in 2009 and $6.7 million in 2008. In November 2010, we received approximately $195.1 million in net proceeds from the issuance of the 2020 Notes, which we used to redeem $170.6 million in principal amount of MSG Notes. In conjunction with the redemption of the MSG Notes, we incurred approximately $8.9 million in tender and consent premiums. Earlier in the year we also redeemed $6.0 million of the MSG Notes. In 2010, we reduced our net borrowings under our revolving credit facility by $76.8 million in addition to reducing other net debt obligations by $2.3 million. In 2009, we reduced our net borrowings under our revolving credit facility by $80.9 million and other net debt obligations of $1.7 million in addition to redeeming $1.1 million principal amount of MSG Notes. In 2008, our borrowings under our revolving credit facility were used primarily to fund the Merger, as well as other related expenses and costs associated with the credit facility. In connection with the Merger we also assumed certain debt obligations, some requiring monthly installment payments. We received $1.1 million, $0.3 million and $1.7 million from the exercises of employee stock options and the related tax benefits in 2008, 2009 and 2010, respectively. As of December 31, 2010, we had $396.9 million of borrowings outstanding under our revolving credit facility, and approximately $385.9 million of additional borrowings were available to us under the facility. Hedging Activities. At December 31, 2010, we had five interest rate swap agreements in place to fix interest rates paid on a total of $125.0 million of our outstanding debt. We entered into interest rate swap agreements that effectively fixed the interest rate so that the rate is payable based upon a spread from fixed rates, rather than a spread from the LIBOR rate. At December 31, 2010, $449.5 million of our outstanding indebtedness bears interest at fixed rates (or the rate is effectively fixed due to a swap agreement), and approximately $271.9 million of borrowings under our credit facility are at a variable rate. 40 Contractual Obligations and Commitments Our contractual obligations primarily consist of our outstanding balance under our revolving credit facility and $372.3 million of Senior Notes, together with other, primarily unsecured notes payable obligations, and obligations under capital leases. We also have operating lease commitments for: (1) real estate properties for the majority of our branches with remaining lease terms typically ranging from 1 to 15 years; (2) 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 (3) office related equipment. At December 31, 2010, primarily in connection with the issuance of our insurance policies, we provided certain insurance carriers and others with approximately $8.8 million in letters of credit. We currently do not have any obligations under purchase agreements or commitments. We enter into operating and capital lease obligations from time to time. At December 31, 2010, we had $2.6 million in capital lease obligations. The table below provides a summary of our contractual commitments as of December 31, 2010. The operating lease amounts include certain real estate leases that expire in 2011, but have lease renewal options that we currently anticipate to exercise in 2011 at the end of the initial lease period.

For further discussion see Note 12 to our Consolidated Financial Statements. (5) The aggregate principal amount outstanding on the MSG Notes ($22.3 million) at December 31, 2010, was redeemed in January 2011. 41 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 some of our customers is somewhat seasonal. Demand for leases of 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. These retailers usually return these leased units to us in December and early in the following year. This seasonality has historically caused lower utilization rates for our lease fleet and a marginal decrease in cash flow during the first quarter of each year. Critical Accounting Policies, Estimates and Judgments Our significant accounting policies are disclosed in Note 1 to our Consolidated Financial Statements. The following discussion addresses our most critical accounting policies, some of which require significant judgment. Our consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses during the reporting period. These estimates and assumptions are based upon our evaluation of historical results and anticipated future events, and these estimates may change as additional information becomes available. The SEC defines critical accounting policies as those that are, in management’s view, most important to our financial condition and results of operations and those that require significant judgments and estimates. Management believes that our most critical accounting policies relate to: Revenue Recognition. Lease and leasing ancillary revenues and related expenses generated under portable storage and mobile office units are recognized on a straight-line basis. Delivery and hauling revenues and expenses from our portable storage and mobile office units are recognized when these services are earned. We recognize revenues from sales of containers and mobile office units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. We sell our products pursuant to sales contracts stating the fixed sales price with our customers. Share-Based Compensation. We recognize the fair-value of share-based compensation transactions in the consolidated statements of income. The fair value of our share-based awards is estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes valuation calculation requires us to estimate key assumptions such as future stock price volatility, expected terms, risk-free rates and dividend yield. Expected stock price volatility is based on the historical volatility of our stock. We use historical data to estimate option exercises and employee terminations within the valuation model. The expected term of options granted is derived from an analysis of historical exercises and remaining contractual life of stock options, and represents the period of time that options granted are expected to be outstanding. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant. We historically have not paid cash dividends, and do not currently intend to pay cash dividends, and thus have assumed a 0% dividend rate. If our actual experience differs significantly from the assumptions used to compute our share-based compensation cost, or if different assumptions had been used, we may have recorded too much or too little share-based compensation cost. In the past we have issued stock options and restricted stock, which we also refer to as nonvested shares. For stock options and nonvested share-awards subject solely to service conditions, we recognize expense using the straight-line method. For nonvested share-awards subject to service and performance conditions, we are required to assess the probability that such performance conditions will be met. In 2010 the share-based compensation expense was reduced by $0.4 million to reflect anticipated shortfalls related to share-awards with vesting subject to a performance conditions. If the likelihood of the performance condition being met is deemed probable, we will recognize the expense using the accelerated attribution method. In addition, for both stock options and nonvested share-awards, we are required to estimate the expected forfeiture rate of our stock grants and only recognize the expense for those shares expected to vest. If the 42 actual forfeiture rate is materially different from our estimate, our share-based compensation expense could be materially different. We had approximately $2.3 million of total unrecognized compensation costs related to stock options at December 31, 2010 that are expected to be recognized over a weighted-average period of 3.8 years and $20.6 million of total unrecognized compensation costs related to nonvested share-awards at December 31, 2010 that are expected to be recognized over a weighted-average period of 3.2 years. See Note 10 to the Consolidated Financial Statements for a further discussion on share-based compensation. Allowance for Doubtful Accounts. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We establish and maintain reserves against estimated losses based upon historical loss experience and evaluation of past due accounts agings. Management reviews the level of the allowances for doubtful accounts on a regular basis and adjusts the level of the allowances as needed. If we were to increase the factors used for our reserve estimates by 25%, it would have the following approximate effect on our net income and diluted earnings per share as follows: As reported: Net income . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Impairment of Goodwill. We assess the impairment of goodwill and other identifiable intangibles on an annual basis or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Some factors we consider important which could trigger an impairment review include the following: (cid:129) significant under-performance relative to historical, expected or projected future operating results; (cid:129) significant changes in the manner of our use of the acquired assets or the strategy for our overall business; (cid:129) our market capitalization relative to net book value; and (cid:129) significant negative industry or general economic trends. We operate in one reportable segment, which is comprised of three operating segments that also represent our reporting units (North America, the U.K. and The Netherlands). All of our goodwill was allocated between these three reporting units. At December 31, 2010, only North America and the U.K. have goodwill subject to impairment testing. We perform an annual impairment test on goodwill at December 31 using a two-step process. The first step is a screen for potential impairment, while the second step measures the amount of the impairment, if any. In addition, we will perform impairment tests during any reporting period in which events or changes in circumstances indicate that an impairment may have incurred. At December 31, 2010, we performed the first step of the two-step impairment test and compared the fair value of each reporting unit to its carrying value. In assessing the fair value of the reporting units, we considered both the market approach and the income approach. Under the market approach, the fair value of the reporting unit is based on quoted market prices of companies comparable to the reporting unit being valued. Under the income approach, the fair value of the reporting unit is based on the present value of estimated cash flows. The income approach is dependent on a number of significant management assumptions, including estimated future revenue growth rates, gross margins on sales, operating margins, capital expenditures, tax payments and discount rate. Each approach was given equal weight in arriving at the fair value of the reporting unit. As of December 31, 2010, neither of the 43 reporting units with goodwill had estimated fair values less than their individual net asset carrying values, therefore step two was not required at December 31, 2010. In step two of the impairment test, we are required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. We allocated the fair value of the reporting units to the respective assets and liabilities of each reporting unit as if the reporting units had been acquired in separate and individual business combinations and the fair value of the reporting units was the price paid to acquire the reporting units. The excess of the fair value of the reporting units over the amounts assigned to their respective assets and liabilities is the implied fair value of goodwill. We reconciled the fair values of our three reporting units in the aggregate to our market capitalization at December 31, 2010. The performance of our 2009 and 2010 annual impairment analyses resulted in no impairment charges to the North America or U.K. reporting units, where all of our goodwill is recorded. A goodwill impairment charge of $13.7 million was recognized in 2008, primarily related to the U.K. reporting unit. The fair value of the North America and U.K. reporting units exceeded the carrying value at December 31, 2010 by 41% and 18%, respectively. At December 31, 2010, $447.3 million of our goodwill relates to the North America reporting unit and $64.1 million relates to the U.K. reporting unit. The discount rates utilized in the 2010 analyses ranged from 11% to 12% while the terminal growth rates used in the discounted cash flow analysis were approximately 2%. Impairment of Long-Lived Assets. We review property, plant and equipment and intangibles with finite lives (those assets resulting from acquisitions) for impairment when events or circumstances indicate these assets might be impaired. We test impairment using historical cash flows and other relevant facts and circumstances as the primary basis for its estimates of future cash flows. This process requires the use of estimates and assumptions, which are subject to a high degree of judgment. If these assumptions change in the future, whether due to new information or other factors, we may be required to record impairment charges for these assets. There were no indicators of impairment at December 31, 2009 and 2010. Depreciation Policy. Our depreciation policy for our lease fleet uses the straight-line method over our units’ estimated useful life, after the date that we put the unit in service. Our steel units are depreciated over 30 years with an estimated residual value of 55%. Wood offices units are depreciated over 20 years with an estimated residual value of 50%. Van trailers, which are a small part of our fleet, are depreciated over 7 years to a 20% residual value. We have other non-core products that have various other measures of useful lives and residual values. Van trailers and other non-core products are only added to the fleet as a result of acquisitions of portable storage businesses. In April 2009, we evaluated our depreciation policy on our steel units and changed the estimated useful life to 30 years (from 25 years) and decreased the residual value to 55% from 62.5%. This results in continual depreciation on steel units for five additional years at the same annual rate of 1.5% of book value. This change had an immaterial impact on the consolidated financial statements at the date of the change in estimate. We made this change because some of our steel units have been in our lease fleet longer than 25 years and these units continue to be effective income producing assets that do not show signs of realizing the end of their useful life. Our historical lease fleet data on our steel units shows we have retained comparable rental rates and sales prices irrespective of the age of the steel units in our lease fleet. We periodically review our depreciation policy against various factors, including the results of our lenders’ independent appraisal of our lease fleet, practices of the larger competitors in our industry, profit margins we are achieving on sales of depreciated units and lease rates we obtain on older units. If we were to change our depreciation policy on our steel units from 55% residual value and a 30-year life to a lower or higher residual and a shorter or longer useful life, such change could have a positive, negative or neutral effect on our earnings, with the actual effect being determined by the change. For example, a change in our estimates used in our residual values 44 and useful life on our steel units would have the following approximate effect on our net income and diluted earnings per share as reflected in the table below.

Our worker’s compensation, auto and general liability insurance are purchased under large deductible programs. Our current per incident deductibles are: worker’s compensation $250,000, auto $500,000 and general liability $100,000. We provide for the estimated expense relating to the deductible portion of the individual claims. However, we generally do not know the full amount of our exposure to a deductible in connection with any particular claim during the fiscal period in which the claim is incurred and for which we must make an accrual for the deductible expense. We make these accruals based on a combination of the claims development experience of our staff and our insurance companies, and, at year end, the accrual is reviewed and adjusted, in part, based on an independent actuarial review of historical loss data and using certain actuarial assumptions followed in the insurance industry. A high degree of judgment is required in developing these estimates of amounts to be accrued, as well as in connection with the underlying assumptions. In addition, our assumptions will change as our loss experience is developed. All of these factors have the potential for significantly impacting the amounts we have previously reserved in respect of anticipated deductible expenses, and we may be required in the future to increase or decrease amounts previously accrued. Contingencies. We are a party to various claims and litigation in the normal course of business. Manage- ment’s current estimated range of liability related to various claims and pending litigation is based on claims for which our 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 reasonable determination of the liability that could result from an unfavorable outcome. As additional information becomes 45 available, we will assess the potential liability related to our pending litigation and revise our estimates. Such revisions in our estimates of the potential liability could materially impact our results of operation. We do not anticipate the resolution of such matters known at this time will have a material adverse effect on our business or consolidated financial position. Deferred Taxes. In preparing our consolidated financial statements, we recognize income taxes in each of the jurisdictions in which we operate. For each jurisdiction, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which it is more likely than not that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income as well as feasible tax planning strategies in each jurisdiction. If we determine that we will not realize all or a portion of our deferred tax assets, we will increase our valuation allowance with a charge to income tax expense or offset goodwill if the deferred tax asset was acquired in a business combination. Conversely, if we determine that we will ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced with a credit to income tax expense except if the valuation allowance was created in conjunction with a tax asset in a business combination. At December 31, 2010, we have a $1.4 million valuation allowance and $135.6 million of deferred tax assets included within the net deferred tax liability on our balance sheet. The majority of the deferred tax asset relates to federal net operating loss carryforwards that have future expiration dates. Management believes that certain state net operating loss carryforwards will expire unused and, as a result, has created a valuation allowance of $0.2 million. Management currently believes that adequate future taxable income will be generated through future operations and, or through available tax planning strategies to recover these assets. However, given that these federal net operating loss carryforwards that give rise to the deferred tax asset expire over 18 years beginning in 2012, there could be changes in management’s judgment in future periods with respect to the recoverability of these assets. As of December 31, 2010, management believes that it is more likely than not that the unreserved portion of these deferred tax assets will be recovered. Purchase Accounting. We account for acquisitions under the purchase method. Under the purchase method of accounting, the price paid by us, including the value of the redeemable convertible preferred stock, if any, is allocated to the assets acquired and liabilities assumed based upon the estimated fair values of the assets and liabilities acquired and the fair value of the convertible redeemable participating preferred stock issued at the date of acquisition. The excess of the purchase price over the fair value of the net assets and liabilities acquired represents goodwill that is subject to annual impairment testing. Earnings Per Share. Basic net income per share is calculated by dividing income allocable to common stockholders by the weighted-average number of common shares outstanding, net of shares subject to repurchase by us during the period. Income allocable to common stockholders is net income less the earnings allocable to preferred stockholders. Diluted net income per share is calculated under the if-converted method unless the conversion of the preferred stock is anti-dilutive to basic net income per share. To the extent the inclusion of preferred stock is anti-dilutive, we calculate diluted net income per share under the two-class method. Potential common shares include restricted common stock and incremental shares of common stock issuable upon the exercise of stock options and vesting of nonvested stock awards and upon conversion of convertible preferred stock using the treasury stock method. 46 Recent Accounting Pronouncements Transfers of Financial Assets. In June 2009, the Financial Accounting Standards Board (FASB) issued guidance that changes the information a reporting entity provides in its financial statements about the transfer of financial assets and continuing interests held in transferred financial assets. The standard amends previous accounting guidance by removing the concept of qualified special purpose entities. This accounting standard became effective for the Company for transfers occurring on or after January 1, 2010. We adopted this accounting standard and it did not have a material effect on our consolidated financial statements and related disclosures. Multiple Element Arrangements. In September 2009, the FASB issued new accounting guidance related to the revenue recognition of multiple element arrangements. The new guidance states that if vendor specific objective evidence or third party evidence for deliverables in an arrangement cannot be determined, companies will be required to develop a best estimate of the selling price to separate deliverables and allocate arrangement consideration using the relative selling price method. This guidance is effective for arrangements entered into after January 1, 2011. We currently do not expect this guidance to have a material impact on our financial statements and disclosures. Fair Value Measurements. In January 2010, the FASB issued guidance which requires new disclosures of significant transfers in and out of Level 1 and Level 2 fair value measurements. The guidance also requires disclosure about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements for Level 2 and Level 3. We adopted the provisions of this guidance on January 1, 2010. The adoption of these provisions did not have a material effect on our consolidated financial statements. Business Combinations. In December 2010, the FASB issued clarification on the accounting guidance for business combinations. The new accounting guidance clarifies the requirement that public entities that have entered into a new business combination during the year, present comparative financial statements disclosing revenue and earnings of the combined entity as though the business combination that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. This guidance is effective for business combinations entered into after January 1, 2011. We currently do not expect this guidance to have a material impact on our financial statements and disclosures. Goodwill. In December 2010, the FASB issued new accounting guidance for goodwill impairment testing. The new accounting guidance states that for reporting units with zero or negative carrying amounts the reporting unit should perform Step 2 of a goodwill impairment after considering the evidence of adverse qualitative factors that an impairment may exist. This guidance is effective for business combinations entered into after January 1, 2011. We currently do not expect this guidance to have a material impact on our financial statements and disclosures. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. Interest Rate Swap Agreement. We seek to reduce earnings and cash flow volatility associated with changes in interest rates through a financial arrangement intended to provide a hedge against a portion of the risks associated with such volatility. We continue to have exposure to such risks to the extent they are not hedged. Interest rate swap agreements are the only instruments we use to manage interest rate fluctuations affecting our variable rate debt. At December 31, 2010, we had five interest rate swap agreements under which we pay a fixed rate and receive a variable interest rate on a notional amount of $125.0 million of debt. In 2010, comprehensive income included $3.4 million, net of income tax expense of $2.2 million, related to the fair value of our interest rate swap agreements. We enter into derivative financial arrangements only to the extent that the arrangement meets the objectives described, and we do not engage in such transactions for speculative purposes. 47 The following table sets forth the scheduled maturities and the total fair value of our debt portfolio: At December 31, 2011 2012 2013 2014 Thereafter 2015 (In thousands, except percentages) Total at December 31, 2010 Total Fair Value at December 31, 2010 Debt: Fixed rate . . . . . . . . . $ 1,577 $ Average interest rate . .

(2) The aggregate principal amount outstanding of the MSG Notes, $22.3 million, was redeemed in January 2011. Impact of Foreign Currency Rate Changes. We currently have branch 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, operations in the U.K. are billed in Pound Sterling and operations in The Netherlands are billed in the Euro. 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 European operations. In order to help minimize our exchange rate gain and loss volatility, we finance our European entities through our revolving line of credit which allows us, at our option, to borrow funds locally in Pound Sterling denominated debt. 48 ITEM 8.

We have audited the accompanying consolidated balance sheets of Mobile Mini, Inc. as of December 31, 2010 and 2009, and the related consolidated statements of income, preferred stock and stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Mobile Mini, Inc. at December 31, 2010 and 2009, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Mobile Mini, Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organiza- tions of the Treadway Commission and our report dated March 1, 2011 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1) Mobile Mini, its Operations and Summary of Significant Accounting Policies: Organization and Special Considerations Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage solutions. In these notes, the terms “Mobile Mini” and the “Company”, refers to Mobile Mini, Inc. At December 31, 2010, Mobile Mini has a fleet of portable storage and office units, and operates throughout the U.S., in Canada, the U.K. and The Netherlands. The Company’s portable storage products offer secure, temporary storage with immediate access. The Company has a diversified customer base, including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. The Company’s customers use its products for a wide variety of applications, including the storage of retail and manufacturing inventory, construction materials and equipment, documents and records and other goods. On June 27, 2008, we acquired Mobile Storage Group, Inc. (MSG) and the discussion in this Annual Report of the Company’s business includes the results of its combined operations with MSG since June 27, 2008. Principles of Consolidation The consolidated financial statements include the accounts of Mobile Mini, Inc. 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. Revenue Recognition Lease and leasing ancillary revenues and related expenses generated under portable storage and mobile office units are recognized on a straight-line basis. Delivery and hauling revenues and expenses from portable storage and mobile office units are recognized when these services are earned. The Company recognizes revenues from sales of containers and mobile office units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. The Company sells its products pursuant to sales contracts stating the fixed sales price with its customers. Cost of Sales Cost of sales in the Company’s consolidated statements of income includes only the costs for units it sells. Similar costs associated with the portable storage units that it leases are capitalized on its balance sheet under “Lease fleet”. Advertising Costs All non direct-response advertising costs are expensed as incurred. Direct-response advertising costs, principally yellow page advertising, are capitalized when paid and amortized over the period in which the benefit is derived. At December 31, 2009 and 2010, prepaid advertising costs were approximately $2.3 million and $1.3 million, respectively. The amortization period of the prepaid balance never exceeds 12 months. The direct- response advertising costs are monitored through the Company’s CRM system and the marketing department. Advertising expense was $12.5 million and $11.4 million and $9.3 million in 2008, 2009 and 2010, respectively. Receivables and Allowance for Doubtful Accounts Receivables primarily consist of amounts due from customers from the lease or sale of containers throughout the U.S., Canada, the U.K. and The Netherlands. Mobile Mini records an estimated provision for bad debts through a charge to operations in amounts of its estimated losses expected to be incurred in the collection of these accounts. The Company reviews the provision for adequacy monthly. The estimated losses are based on historical collection experience and evaluation of past-due account agings. Specific accounts are written off against the allowance when 55 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. management determines the account is uncollectible. The Company requires a security deposit on most leased office units to cover the cost of damages or unpaid balances, if any. Concentration of Credit Risk Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of receivables. Concentration of credit risk with respect to receivables is limited due to the Company’s large number of customers spread over a broad geographic area in many industry segments. No single customer accounts for more than 10.0% of our receivables at December 31, 2009 and December 31, 20010. Receivables related to its sales operations are generally secured by the product sold to the customer. Receivables related to its leasing operations are primarily small month-to-month amounts. The Company has the right to repossess leased portable storage units, including any customer goods contained in the unit, following non-payment of rent. 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. Inventories primarily consist of raw materials, supplies, work-in-process and finished goods, all related to the manufacturing, remanufacturing and maintenance, primarily for the Company’s lease fleet and its units held for sale. Raw materials principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes. Work-in-process primarily represents units being built that are either pre-sold or being built to add to its lease fleet upon completion. Finished portable storage units primarily represent ISO (International Organization for Standardization) containers held in inventory until the containers are either sold as is, reman- ufactured and sold, or units in the process of being remanufactured to be compliant with the Company’s lease fleet standards before transferring the units to its lease fleet. There is no certainty when the Company purchases the containers whether they will ultimately be sold, remanufactured and sold, or remanufactured and moved into its lease fleet. Units that are determined to go into the Company’s lease fleet undergo an extensive remanufacturing process that includes installing its proprietary locking system, signage, painting and sometimes its proprietary security doors.

Depreciation is provided using the straight-line method over the assets’ estimated useful lives. Residual values are determined when the property is constructed or acquired and range up to 25%, depending on the nature of the asset. In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. The Company’s depreciation expense related to property, plant and equipment for 2008, 2009 and 2010 was $9.4 million, $12.1 million and $11.3 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 retirement of fixed assets and is included in leasing, selling and general expenses in the Consolidated Statements of Income. 56 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC.

Other Assets and Intangibles Other assets and intangibles primarily represent deferred financing costs and intangible assets from acqui- sitions of $44.8 million at December 31, 2009 and $49.2 million at December 31, 2010, excluding accumulated amortization of $18.2 million at December 31, 2009 and $25.7 million at December 31, 2010. Deferred financing costs are amortized over the term of the agreement, and intangible assets are amortized on a straight-line basis, typically from five to 20 years, depending on its useful life. Intrinsic values assigned to customer relationships and trade names are amortized on an accelerated basis, typically over 15 years. The following table reflects balances related to other assets and intangible assets for the years ended December 31: Gross Carrying Amount $21,831 21,572 943 273 218 2009 Accumulated Amortization $ (7,977) (9,266) (750) (123) (78) Net Carrying Amount Gross Carrying Amount (In thousands) $13,854 12,306 193 150 140 $26,269 21,313 926 250 414 Deferred financing costs . . . . . .

The annual amortization of deferred financing costs is expected to be $4.1 million in 2011, $4.1 million in 2012, $2.5 million in 2013, $0.9 million in 2014 and $3.0 million thereafter. Amortization expense for all other intangibles was approximately $3.7 million, $5.6 million and $4.0 million in 2008, 2009 and 2010, respectively. Based on the carrying value at December 31, 2010, and assuming no 57 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. subsequent impairment of the underlying assets, the annual amortization expense is expected to be $2.9 million in 2011, $2.1 million in 2012, $1.5 million in 2013, $1.0 million in 2014 and $1.4 million thereafter. Income Taxes Mobile Mini utilizes the liability method of accounting for income taxes where deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Income tax expense includes both taxes payable for the period and the change during the period in deferred tax assets and liabilities. Earnings per Share The Company’s preferred stock participates in distributions of earnings on the same basis as shares of common stock. Earnings for the period are allocated between the common and preferred shareholders based on their respective rights to receive dividends. Basic net income per share is then calculated by dividing income allocable to common stockholders by the weighted-average number of common shares outstanding, net of shares subject to repurchase by the Company, during the period. The Company is not required to present basic and diluted net income (loss) per share for securities other than common stock; therefore, the following net income per share amounts only pertain to the Company’s common stock. The Company calculates diluted net income per share under the if- converted method unless the conversion of the preferred stock is anti-dilutive to basic net income per share. To the extent the inclusion of preferred stock is anti-dilutive, the Company calculates diluted net income per share under the two-class method.

Long Lived Assets Mobile Mini reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. If this review indicates the carrying value of these assets will not be recoverable, as measured based on estimated undiscounted cash flows over their remaining life, the carrying amount would be adjusted to fair value. The cash flow estimates contain management’s best estimates, using appropriate and customary assumptions and projections at the time. The Company did not recognize any impairment losses in the years ended December 31, 2009 and 2010. Goodwill Purchase prices of acquired businesses have been allocated to the assets and liabilities acquired based on the 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 were allocated to goodwill. Acquisitions of businesses under asset purchase agreements results in the goodwill relating to business acquisition being deductible for income tax purposes over 15 years even though goodwill is not amortized for financial reporting purposes. The Company did not have any acquisitions through mergers, asset purchase or stock purchase agreements either in 2009 or 2010. The Company evaluates goodwill periodically to determine whether events or circumstances have occurred that would indicate goodwill might be impaired. The Company originally had assigned its goodwill to each of its three reporting units (North America, the U.K. and The Netherlands). At December 31, 2010, only North America and the U.K. have goodwill subject to impairment testing. The Company performs an annual impairment test on goodwill at December 31 using the two-step process. The first step is a screen for potential impairment, while the second step measures the amount of the impairment, if any. In addition, the Company will perform impairment tests during any reporting period in which events or changes in circumstances indicate that an impairment may have incurred. At December 31, 2010, the Company performed the first step of the two-step impairment test and compared the fair value of each reporting unit to its carrying value. In assessing the fair value of the reporting units, the Company considered both the market and income approaches. Under the market approach, the fair value of the reporting unit is based on quoted market prices of companies comparable to the reporting unit being valued. Under the income approach, the fair value of the reporting unit is based on the present value of estimated cash flows. The income approach is dependent on a number of significant management assumptions, including estimated future revenue growth rates, gross margins on sales, operating margins, capital expenditure, tax payments and discount rates. Each approach was given equal weight in arriving at the fair value of the reporting unit. As of December 31, 2010, neither of the Company’s two remaining reporting units with goodwill had estimated fair values less than the reporting units’ individual net asset carrying values, therefore, step two of the impairment test was not required at December 31, 2010. If step two of the impairment test is necessary, the Company is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The Company would allocate the fair value of the reporting units to the respective assets and liabilities of each reporting unit as if the reporting units had been acquired in separate and individual business combinations and the fair value of the reporting units was the price paid to acquire the reporting units. The excess of the fair value of the reporting units over the amounts assigned to their respective assets and liabilities is the implied fair value of goodwill. The Company reconciled the fair values of its two reporting units in the aggregate to its market capitalization at December 31, 2010. At December 31, 2010, $447.3 million of the goodwill relates to the North America reporting unit, and $64.1 million relates to the U.K. reporting unit. The fair value of the North America and U.K. reporting units exceeded the carrying value at December 31, 2010 by 41% and 18%, respectively. 60 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC.

Fair Value of Financial Instruments The Company determines the estimated fair value of financial instruments using available market information and valuation methodologies. Considerable judgment is required in estimating fair values. Accordingly, the estimates may not be indicative of the amounts it could realize in a current market exchange. The carrying amounts of cash, receivables, accounts payable and accrued liabilities approximate fair values based on the liquidity of these financial instruments or based on their short-term nature. The carrying amounts of the Company’s borrowings under its credit facility and notes payable approximate fair value. The fair values of the Company’s notes payable and credit facility are estimated using discounted cash flow analyses, based on its 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 fixed rate notes payable at December 31, 2009 and 2010, approximated their respective book values. The fair value of the Company’s $150.0 million aggregate principal amount of 6.875% senior notes due 2015 (the 2015 Notes), its $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the 2020 Notes, and together with the 2015 Notes, the Mobile Mini Notes) and its $200.0 million aggregate principal amount of 9.750% senior notes originally issued by MSG due 2014 (the MSG Notes and together with the Mobile Mini Notes, the Senior Notes), is based on the latest sales price of the notes at the end of each period obtained from a third-party institution. The carrying value and the fair value of the Company’s Senior Notes are as follows: December 31, 2009 December 31, 2010 (In thousands) Carrying value . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $345,402 $371,655 Fair value . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $348,500 $375,608 Deferred Financing Costs Included in other assets and intangibles are deferred financing costs of approximately $13.9 million and $14.6 million, net of accumulated amortization of $8.0 million and $11.7 million, at December 31, 2009 and 2010, respectively. Costs of obtaining long-term financing, including the Company’s amended credit facility, are amortized over the term of the related debt, using the straight-line method. Amortizing the deferred financing costs using the straight-line method approximates the effective interest method. 61 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. Derivatives In the normal course of business, the Company’s operations are exposed to fluctuations in interest rates. The Company addresses a portion of these risks through a controlled program of risk management that includes the use of derivative financial instruments. The objective of controlling these risks is to limit the impact of fluctuations in interest rates on earnings. The Company’s primary interest rate risk exposure results from changes in short-term U.S. dollar interest rates. In an effort to manage interest rate exposures, the Company may enter into interest rate swap agreements, which convert its floating rate debt to a fixed-rate and which it designates as cash flow hedges. Interest expense on the notional amounts under these agreements is accrued using the fixed rates identified in the swap agreements. Mobile Mini had interest rate swap agreements totaling with an aggregate notional amount of $200 million and $125 million at December 31, 2009 and December 31, 2010, respectively. The fixed interest rate on the Company’s five swap agreements at December 31, 2010 range from 3.25% to 3.87% plus the spread. The swap agreements mature in 2011. The following tables summarize information related to the Company’s derivatives. All of the Company’s derivatives are designated as effective hedging instruments in cash flow hedging relationships.

Fair Value (In thousands) $(7,703) $(2,124) Amount of Gain Recognized in Other Comprehensive Income on Derivatives (In thousands) $2,335 $3,417 Share-Based Compensation At December 31, 2010, the Company had one active share-based employee compensation plan. There are two expired compensation plans, one of which still has outstanding options subject to exercise or termination. No additional options can be granted under the expired plans. Stock option awards under these plans are granted with an exercise price per share equal to the fair market value of the Company’s common stock on the date of grant. Each outstanding option must expire no more than 10 years from the date it was granted, unless exercised or forfeited before the expiration date, and historically options are granted with vesting over a 4.5 year period. The total value of the Company’s stock option awards is expensed over the related employee’s service period on a straight-line basis. The Company uses the modified prospective method and does not recognize a deferred tax asset for any excess tax benefit that has not been realized related to stock-based compensation deductions. The Company adopted the with-and-without approach with respect to the ordering of tax benefits realized. In the with-and-without approach, the excess tax benefit related to stock-based compensation deductions will be recognized in additional paid-in capital only if an incremental tax benefit would be realized after considering all other tax benefits presently available to us. Therefore, the Company’s net operating loss carryforward will offset current taxable income prior to the recognition of the tax benefit related to stock-based compensation deductions. In 2008 and 2010 there were $0.4 million and $2.4 million, respectively, of excess tax benefits related to stock-based compensation, which were 62 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. not realized under this approach. In 2009, no excess tax benefit was generated, as instead a $1.3 million tax deduct shortfall occurred, which was applied against previously recognized benefits. Once the Company’s net operating loss carryforward is utilized, these excess tax benefits, totaling $8.5 million, may be recognized in additional paid- in capital. Foreign Currency Translation and Transactions For Mobile Mini’s non-U.S. operations, the local currency is the functional currency. All assets and liabilities are translated into U.S. dollars at period-end exchange rates and all income statement amounts are translated at the average exchange rate for each month within the year. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. 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 included within the financial statements are the allowance for doubtful accounts, the estimated useful lives and residual values on the lease fleet and property, plant and equipment and goodwill and other asset impairments. Impact of Recently Issued Accounting Standards Transfers of Financial Assets. In June 2009, the Financial Accounting Standards Board (FASB) issued guidance that changes the information a reporting entity provides in its financial statements about the transfer of financial assets and continuing interests held in transferred financial assets. The standard amends previous accounting guidance by removing the concept of qualified special purpose entities. This accounting standard is effective for the Company for transfers occurring on or after January 1, 2010. The Company adopted this accounting standard and it did not have a material effect on its consolidated financial statements and related disclosures. Fair Value Measurements. In January 2010, the FASB issued guidance which requires new disclosures of significant transfers in and out of Level 1 and Level 2 fair value measurements. The guidance also requires disclosure about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements for Level 2 and Level 3. The Company adopted the provisions of this guidance on January 1, 2010. The adoption of these provisions did not have a material effect on the Company’s consolidated financial statements. Business Combinations. In December 2010, the FASB issued clarification on the accounting guidance for business combinations. The new accounting guidance clarifies the requirement that public entities that have entered into a new business combination during the year, present comparative financial statements disclosing revenue and earnings of the combined entity as though the business combination that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. This guidance is effective for business combinations entered into after January 1, 2011. The Company currently does not expect this guidance to have a material impact on its financial statements and disclosures. Goodwill. In December 2010, the FASB issued new accounting guidance for goodwill impairment testing. The new accounting guidance states that for reporting units with zero or negative carrying amounts the reporting unit should perform Step 2 of a goodwill impairment after considering the evidence of adverse qualitative factors that an impairment may exist. This guidance is effective for business combinations entered into after January 1, 2011. The Company currently does not expect this guidance to have a material impact its financial statements and disclosures. 63 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. (2) 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 liability. As a basis for considering such assumptions, the Company adopted the suggested accounting guidance for the three levels of inputs that may be used to measure fair value: Level 1 Observable input 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. Assets and liabilities measured at fair value on a recurring basis are as follows: Interest Swap Agreements Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) December 31, 2009 . . . . . . . . . . . December 31, 2010 . . . . . . . . . . . $(7,703) $(2,124) $— $— Significant Other Observable Inputs (Level 2) (In thousands) $(7,703) $(2,124) Significant Unobservable Inputs (Level 3) Valuation Technique $— $— (1) (1) (1) The Company’s interest rate swap agreements are not traded on a market exchange; therefore, the fair values are determined using valuation models which include assumptions about the LIBOR yield curve at the reporting dates as well as counterparty credit risk and the Company’s own non-performance risk. The Company has consistently applied these calculation techniques to all periods presented. At December 31, 2009 and 2010, the fair value of interest rate swap agreements is recorded in accrued liabilities in the Company’s Consolidated Balance Sheets. (3) Lease Fleet Mobile Mini’s lease fleet primarily consists of remanufactured, modified and manufactured portable storage and office units that are leased to customers under short-term operating lease agreements with varying terms. Depreciation is provided using the straight-line method over the units’ estimated useful life, after the date the Company put the unit in service, and are depreciated down to their estimated residual values. The Company’s depreciation policy on its steel units uses an estimated useful life of 30 years with an estimated residual value of 55%. Wood mobile office units are depreciated over 20 years down to a 50% residual value. Van trailers, which are a small part of the Company’s fleet, are depreciated over 7 years to a 20% residual value. Van trailers and other non- core assets are only added to the fleet in connection with acquisitions of portable storage businesses. In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. The Company continues to evaluate these depreciation policies as more information becomes available from other comparable sources and its own historical experience. The Company’s depreciation expense related to lease fleet for 2008, 2009 and 2010 was $18.9 million, $21.4 million and $20.8 million, respectively. At December 31, 2009 64 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. and 2010, all of the Company’s lease fleet units were pledged as collateral under the credit facility (see Note 4). Normal repairs and maintenance to the portable storage and mobile office units are expensed as incurred.

On June 27, 2008, Mobile Mini and its subsidiaries, (including Mobile Storage Group and its subsidiaries) entered into an ABL Credit Agreement (the Credit Agreement) with Deutsche Bank AG New York Branch and other lenders party thereto. The Credit Agreement provided for a five-year, $900.0 million revolving credit facility. In August 2010, Mobile Mini entered into a Second Amendment to the Credit Agreement which allowed the Company to reduce the Credit Agreement by $50.0 million to $850.0 million. In addition, the amendment provides for (1) new defined terms in the Credit Agreement relating to a permitted refinancing of the Company’s senior notes and (ii) revisions to the “Payment Conditions” (as defined in the Credit Agreement) allowing restricted payments and acquisitions to occur without financial covenants so long as the Company has $250.0 million of pro forma excess borrowing availability under the facility. 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 margins for each type of loan will range from 2.25% to 2.75% for LIBOR loans and 0.75% to 1.25% for base rate loans depending upon the Company’s debt ratio at each measurement date. All amounts outstanding under the Credit Agreement are due on June 27, 2013. 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), machinery and equipment and real property, each multiplied by an applicable advance rate or limit. The lease fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the lesser of cost or appraised orderly liquidation value, as defined, may be included in the borrowing base to determine how much the Company may borrow under this facility. The Credit Agreement provides for U.K. borrowings, denominated in either Pounds Sterling or Euros, by the Company’s subsidiary Mobile Mini U.K. Limited based upon a U.K. borrowing base and for U.S. borrowings, which are denominated in U.S. Dollars, by Mobile Mini based upon a U.S. and Canada borrowing base. The Company’s obligations and those of its subsidiaries under the Credit Agreement are secured by a blanket lien on substantially all of the Company’s assets. 65 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. The Credit Agreement also contains customary negative covenants applicable to Mobile Mini and its subsidiaries, including covenants that restrict their ability to, among other things, (i) make capital expenditures in excess of defined limits, (ii) allow certain liens to attach to the Company or its subsidiary assets, (iii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iv) incur additional indebtedness or engage in certain other types of financing transactions, and (v) make acquisitions or other investments. Mobile Mini also must comply with specified financial covenants and affirmative covenants. Only if the Company falls below specified borrowing availability levels are financial maintenance covenants applicable, with set maximum permitted values for its leverage ratio (as defined), fixed charge coverage ratios and its minimum required utilization rates. At December 31, 2009 and December 31, 2010, the Company was above the minimum borrowing availability threshold and therefore not subject to these financial maintenance covenants. The weighted average interest rate under the line of credit, including the effect of applicable interest rate swap agreements, was approximately 4.4% in 2009 and 4.7% in 2010. The average balance outstanding was approx- imately $531.9 million and $448.4 million during 2009 and 2010, respectively. Mobile Mini has interest rate swap agreements under which it effectively fixed the interest rate payable on $125.0 million of borrowings under the Company’s credit facility so that the interest rate is based on a spread from a fixed rate rather than a spread from the LIBOR rate. The aggregate change in the fair value of the interest rate swap agreements resulted in comprehensive income of $2.3 million and $3.4 million, net of applicable income taxes of $1.5 million and $2.2 million for the years ended December 31, 2009 and 2010, respectively.

The lease agreements provide the Company with a purchase option at the end of the lease term. The leases have been capitalized using interest rates ranging from approximately 5.7% to 8.5%. The leases are secured by the equipment under lease. Assets recorded under capital lease obligations totaled approximately $6.9 million as of December 31, 2009 and $6.8 million as of December 31, 2010. Related accumulated amortization totaled approximately $700,000 as of December 31, 2009 and $1.2 million as of December 31, 2010.

The 2020 Notes were issued by the Company at an initial offering price of 100% of their face value. The net proceeds from the sale of the 2020 Notes were used to redeem approximately $170.6 million of the outstanding MSG Notes due 2014, which were originally issued by MSG and assumed by the Company in connection with the acquisition of MSG in June 2008, to pay the redemption and tender offer premium (approximately $8.9 million) and accrued interest (approximately $5.2 million) on the MSG Notes, and to pay fees and expenses related to the offering. We used the remaining net proceeds of approximately $10.4 million to repay borrowings under our revolving credit facility. In January 2011, the remaining principal amount outstanding on the MSG Notes, $22.3 million, was redeemed pursuant to the terms of the Indenture. The 2020 Notes have a ten-year term and mature on December 1, 2020. The 2020 Notes bear interest at a rate of 7.875% per year, accruing from November 23, 2010. Interest on the 2020 Notes is payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2011. The 2020 Notes are senior unsecured obligations of the Company and are unconditionally guaranteed on a senior unsecured basis by all of our domestic subsidiaries. On November 22, 2010, Mobile Mini entered into a Second Supplemental Indenture with Wells Fargo Bank, N.A., as trustee (the Second Supplemental Indenture), in connection with the Company’s cash tender offer and consent solicitation for the MSG Notes. Pursuant to the Second Supplemental Indenture, substantially all of the restrictive covenants and certain events of default found in the indenture governing the MSG Notes were removed. The Indenture was terminated in January 2011 with the redemption of the remaining outstanding MSG Notes.

The shares were determined to have an initial fair value of $196.6 million based upon a third party valuation. The outstanding shares had a liquidation preference of $147.4 million at December 31, 2009 and at December 31, 2010. The preferred stock votes with Mobile Mini’s common stock as a single class. It ranks senior to the common stock only with respect to distributions upon the occurrence of the bankruptcy, liquidation, dissolution or winding up of Mobile Mini. Holders of a majority of the shares of preferred stock, may require the Company to redeem all of the outstanding preferred stock (i) if the Company enters into a binding agreement in respect of a sale of the Company (as defined in the Certificate of Designation for the preferred stock) at a sale price of less than $23.00 per share or (ii) at any time after the tenth anniversary of the preferred stock issuance date. If such majority holders do not exercise their redemption rights following either of these events, the Company at its option may redeem the preferred stock. These outstanding shares of preferred stock are convertible into an aggregate of 8.2 million shares of the Company’s common stock at any time at the option of the holders, representing an initial conversion price of $18.00 per common share. The preferred stock will be mandatorily convertible into the Company’s common stock if, after the first anniversary of the issuance thereof, its common stock trades above $23.00 per share for a period of 30 consecutive days. In 2009, 364,587 shares of preferred stock were converted to an equal number of shares of common stock. The preferred stock will not have any cash or payment-in-kind dividends (unless and until a dividend is paid with respect to the common stock, in which case dividends will be paid on an equal basis with the common stock, on an as-converted basis) and does not impose any financial covenants upon the Company. Under a Stockholders Agreement entered into with the sellers of MSG, Mobile Mini filed a registration statement on Form S-3 under the Securities Act of 1933, as amended, on April 28, 2009, as amended on June 19, 2009, covering all of the shares of Mobile Mini common stock issuable upon conversion of the preferred stock and any shares of its common stock received in respect of the preferred stock (called the registrable securities) then held by any Mobile Storage Group stockholders party to the Stockholders Agreement to enable the resale of such registrable securities after June 27, 2009. The registration rights granted in the Stockholders Agreement are subject to customary restrictions such as blackout periods and limitations on the number of shares to be included in any underwritten offering imposed by the managing underwriter. In addition, the Stockholders Agreement contains other limitations on the timing and ability of the holders of registrable securities to exercise demands. 68 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC.

A deferred U.S. tax liability has not been provided on the undistributed earnings of certain foreign subsidiaries because it is Mobile Mini’s intent to permanently reinvest such earnings. Undistributed earnings of foreign subsidiaries, which have been, or are intended to be, permanently invested, aggregated approximately $0.1 million and $3.2 million as of December 31, 2009 and 2010, respectively. A net deferred tax liability of approximately $11.9 million related to the Company’s U.K. and The Netherlands operations have been combined with the net deferred tax liabilities of its U.S. operations in the Consolidated Balance Sheets at December 31, 2010.

At December 31, 2010, the Company had net operating loss carryforwards in the various states in which it operates totaling $208.3 million, which expire if unused from 2011 to 2030. At December 31, 2009 and 2010, the Company’s deferred tax assets do not include $5.5 million and $8.5 million of excess tax benefits from employee stock option exercises that are a component of its net operating loss carryforward. Additional paid in capital will be increased by $8.5 million if and when such excess tax benefits are realized. Management evaluates the ability to realize its deferred tax assets on a quarterly basis and adjusts the amount of its valuation allowance if necessary. In 2010, the Company recorded a valuation allowance of $0.2 million related to various state net operating losses that expired in 2010 or will expire in 2011. Accelerated tax amortization primarily relates to amortization of goodwill for income tax purposes. Mobile Mini adopted 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 process, 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. 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, the Company’s tax years for 2008 and 2009 are subject to tax examination by the U.S. Internal Revenue Service through September 15, 2012 and 2013, respectively. No reserves for uncertain income tax positions have been recorded. 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’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 are recorded in leasing, selling and general expenses in its Consolidated Statements of Income. As a result of stock ownership changes during the years presented, it is possible that the Company has undergone a change in ownership for federal income tax purposes, which can limit the amount of net operating loss currently available as a deduction. Management has determined that even if such an ownership change has occurred, it would not impair the realization of the deferred tax asset resulting from the federal net operating loss carryover. 70 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. Mobile Mini paid income taxes of approximately $0.7 million, $0.9 million and $0.8 million in 2008, 2009 and 2010, respectively. These amounts are lower than the recorded expense in the years due to net operating loss carryforwards and general business credit utilization. (9) Transactions with Related Persons: When Mobile Mini was a private company prior to 1994, it leased some of its properties from entities originally controlled by its founder, Richard E. Bunger, and his family members. These related party leases remain in effect. The Company leases a portion of the property comprising its Phoenix location and the property comprising its Tucson location from entities owned by Steven G. Bunger and his siblings. Steven G. Bunger is Mobile Mini’s President and Chief Executive Officer and has served as its Chairman of the Board since February 2001. Annual lease payments under these leases totaled approximately $98,000, $178,000 and $202,000 in 2008, 2009 and 2010, respectively. The term of each of these leases expire on December 31, 2013. Mobile Mini leases its Rialto, California facility from Mobile Mini Systems, Inc., a corporation wholly owned by Barbara M. Bunger, the mother of Steven G. Bunger. Annual lease payments in 2008, 2009 and 2010 under this lease were approximately $295,000, $307,000 and $317,000, respectively. The Rialto lease expires on April 1, 2016. Management believes that the rental rates reflect the fair market rental value of these properties or were less than the fair market rental value. The terms of these related persons lease agreements have been reviewed and approved by the independent directors who comprise a majority of the members of the Company’s Board of Directors. It is Mobile Mini’s intention not to enter into any additional related person transactions other than extensions of these lease agreements. (10) Share-Based Compensation: The Company awarded stock options and nonvested shares under the existing share-based compensation plans. The majority of these options and nonvested share-awards vest in equal annual installments over a four to five year period. The total value of these options and awards is expensed on a straight-line basis over the service period of the employees receiving the grants. The “service period” is the time during which the employees receiving grants must remain employees for the shares granted to fully vest. The Company also grants its executive officers nonvested share-awards with vesting subject to a performance conditions. Vesting for these share-awards is dependent upon the officers fulfilling the service period requirements, as well as the Company meeting certain EBITDA targets in each of the next four years after the grant is awarded. The Company is required to assess the probability that such performance conditions will be met. If the likelihood of the performance condition being met is deemed probable, the Company will recognize the expense using accelerated attribution method. The accelerated attribution method could result in as much as 50% of the total value of the shares being recognized in the first year of the service period if each of the four future targets is assessed as probable of being met. In 2009 and 2010, the share-based compensation expense was reduced by $1.4 million, and $0.4 million, respectively, to reflect anticipated shortfalls related to share-awards with vesting subject to a performance conditions. Share-based payment expense related to the vesting of options and share-awards was approximately $3.5 million, $4.3 million and $5.8 million for 2008, 2009 and 2010, respectively. As of December 31, 2010, the unrecognized compensation cost related to share-awards was approximately $20.6 million, which is expected to be recognized over a weighted-average period of approximately 3.2 years. As of December 31, 2010, total unrecognized compensation cost related to stock option awards was approximately $2.3 million and the related weighted-average period over which it is expected to be recognized is approximately 3.8 years. The cash flows resulting from the tax benefits arising from tax deductions in excess of the compensation cost recognized from the exercise of stock options (excess tax benefits) are classified as financing cash flows. As of December 31, 2010, the Company had no tax benefits arising from tax deductions in excess of the compensation cost recognized because the benefit has not been “realized” given that the Company currently has net operating loss carryforwards and follow the with-and-without approach with respect to the ordering of tax benefits realized. 71 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC.

The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes option pricing model.

In addition, option valuation models require the input of assumptions including expected stock price volatility. The risk-free interest rate is based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options and volatility rates are based on our historical data. We do not anticipate paying a dividend, and therefore no expected dividend yield was used. The weighted average fair value of stock options granted was $8.23 for 2010. Mobile Mini did not grant stock options under the share-based compensation plan during 2008 or 2009. (11) Benefit Plans: Stock Option and Equity Incentive Plans In August 1994, Mobile Mini’s Board of Directors adopted the Mobile Mini, Inc. 1994 Stock Option Plan, which was amended in 1998 and expired (with respect to granting additional options) in 2003. At December 31, 2010, there were no outstanding options to acquire shares under the 1994 Plan. In August 1999, the Company’s Board of Directors approved the Mobile Mini, Inc. 1999 Stock Option Plan, which expired (with respect to granting additional options) in August 2009. As of December 31, 2010, there were outstanding options to acquire 1.33 million shares under the 1999 Plan. Both plans and amendments were approved by the stockholders at annual meetings. Awards granted under the 1999 Plan may be incentive stock options, which are intended to meet the requirements of Section 422 of the Internal Revenue Code, nonstatutory stock options or shares of restricted stock awards. Incentive stock options may be granted to the Company’s officers and other employees. Nonstatutory stock options may be granted to directors and employees, and to non-employee service providers and share-awards may be made to officers and other employees. In February 2006, Mobile Mini’s Board of Directors approved the 2006 Equity Incentive Plan that was subsequently approved by the stockholders at the Company’s 2006 Annual Meeting. At the Annual Stockholders’ Meeting in June 2009, the stockholders approved an amendment to the 2006 Equity Incentive Plan to increase the maximum number of shares that could be issued by an additional 3.0 million shares. The 2006 Plan is an “omnibus” 73 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. stock plan permitting 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 stock-based awards. Participants in the 2006 Plan may be granted any one of the equity awards or any combination of them, as determined by the Board of Directors or the Compensation Committee. The 2006 Plan, as amended, has reserved 4.2 million shares of common stock for issuance. As of December 31, 2010, there were outstanding options to acquire 291,000 shares under the 2006 Plan. The purpose of these plans is to attract and retain the best available personnel for positions of substantial responsibility and to provide incentives to, and to encourage ownership of stock by, Mobile Mini’s management and other employees. The Board of Directors believes that stock options and other share-based awards are important to attract and to encourage the continued employment and service of officers and other employees and encourage them to devote their best efforts to the Company’s business, thereby advancing the interest of its stockholders. The option exercise price for all options granted under these plans may not be less than 100% of the fair market value of the common stock on the date of grant of the option (or 110% in the case of an incentive stock option granted to an optionee beneficially owning more than 10% of the outstanding common stock). The maximum option term is ten years (or five years in the case of an incentive stock option granted to an optionee beneficially owning more than 10% of the outstanding common stock). Payment for shares purchased under these plans is made in cash. Options may, if permitted by the particular option agreement, be exercised by directing that certificates for the shares purchased be delivered to a licensed broker as agent for the optionee, provided that the broker tenders to Mobile Mini, cash or cash equivalents equal to the option exercise price. The plans are administered by the Compensation Committee of Mobile Mini’s Board of Directors. The Compensation Committee is comprised of independent directors. They determine whether options will be granted, whether options will be incentive stock options, nonstatutory option, restricted stock, or performance stock, which officers, employees and service providers will be granted options, the vesting schedule for options and the number of options to be granted. Each outstanding option must expire no more than 10 years from the date it was granted, unless exercised or forfeited before the expiration date, and historically options are granted with vesting over a 4.5 year period. Each non-employee director serving on the Company’s Board of Directors receives an automatic award of shares of Mobile Mini’s common stock equivalent to $82,500 based on the closing price of the Company’s common stock on August 1 of that year, or the following trading day if August 1 is not a trading day. These awards vest 100% when granted. The Board of Directors may amend the plans at any time, except that approval by Mobile Mini’s stockholders may be required for an amendment that increases the aggregate number of shares which may be issued pursuant to each plan, changes the class of persons eligible to receive incentive stock options, modifies the period within which options may be granted, modifies the period within which options may be exercised or the terms upon which options may be exercised, or increases the material benefits accruing to the participants under each plan. The Board of Directors may terminate or suspend the plans at any time. Unless previously terminated, the 2006 Plan will expire in February 2016. Any option granted under a plan will continue until the option expiration date, notwithstanding earlier termination of the plan under which the option was granted. In 2005, the Company began awarding nonvested shares under the existing share-based compensation plans. These nonvested shares vest in equal annual installments on each of the first four or five annual anniversaries of the award date, unless the person to whom the award was made is not then employed by Mobile Mini (or one of its subsidiaries). In 2009 and 2010 certain officers of the Company received performance based nonvested shares. The Company did not grant performance based shares in 2008. If employment terminates, the nonvested shares are forfeited by the former employee. In June 2008, in conjunction with the Merger and the hiring of Mobile Storage Group’s employees, the Company awarded nonvested share-awards for an aggregate of 157,535 shares with an aggregate fair value of 74 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. $3.2 million. These awards vest over a period of between one and five years. The total value of these awards is expensed on a straight-line basis over the service period. 401(k) and Retirement Plans In 1995, the Company established a contributory retirement plan in the U.S., the 401(k) Plan, covering eligible employees with at least one year of service. The 401(k) Plan is designed to provide tax-deferred retirement benefits to employees in accordance with the provisions of Section 401(k) of the Internal Revenue Code. The 401(k) Plan provides that each participant may annually contribute a fixed amount or a percentage of his or her salary, not to exceed the statutory limit. Mobile Mini may make a qualified non-elective contribution in an amount it determines. Under the terms of the 401(k) Plan, Mobile Mini may also make discretionary profit sharing contributions. Profit sharing contributions are allocated among participants based on their annual compensation. Each participant has the right to direct the investment of their funds among certain named plans. Mobile Mini can contribute 25% of its employees’ first 4% of contributions up to a maximum of $2 thousand per employee. The Company has a similar plan as governed and regulated by Canadian law, where the Company makes matching contributions with the same limitations as its 401(k) plan, to its Canadian employees. In the U.K., the Company’s employees are covered by a defined contribution program. The employees become eligible to participate three months after they begin employment. The plan is designed as a retirement benefit program into which the Company pays a fixed 7% of the annual employees’ salary into the plan. Each employee has the election to make further contributions if they so elect. The participants have the right to direct the investment of their funds among certain named plans. A charge of 1% is deducted annually from each employee’s fund to cover the administrative costs of this program. In The Netherlands, the Company’s employees are covered by a defined contribution program. All employees become eligible after one month of employment. Contributions are based on a pre-defined percentage of the employee’s earnings. The percentage contribution is based on the employee’s age, with two-thirds of the contribution made by the Company and one-third made by the employee. The administrative costs for this plan are deducted by the administrative agent from the contributions and the investment earnings. In 2010, Mobile Mini did not make any contributions to the retirement plan in the U.S. Mobile Mini made contributions to these plans of approximately $0.7 million, $0.5 million and $0.3 million in 2008, 2009 and 2010, respectively. The Company incurred approximately $11,700, $26,100 and $26,500 in 2008, 2009 and 2010, respectively, for administrative costs for these programs. (12) Commitments and Contingencies: Leases As discussed more fully in Note 9, Mobile Mini is obligated under four noncancelable operating leases with related parties. The Company also leases its corporate offices and other properties and operating equipment from third parties under noncancelable operating leases. Rent expense under these agreements was approximately $12.3 million, $16.4 million and $18.0 million for the years ended December 31, 2008, 2009 and 2010, respectively. 75 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC.

See Note 14 for a further discussion on restructuring related commitments. Insurance The Company maintains insurance coverage for its operations and employees with appropriate aggregate, per occurrence and deductible limits as the Company reasonably determines is necessary or prudent with current operations and historical experience. The majority of these coverages have large deductible programs which allow for potential improved cash flow benefits based on its loss control efforts. The Company’s employee group health insurance program is a self-insured program with an aggregate stop loss limit. The insurance provider is responsible for funding all claims in excess of the calculated monthly maximum liability. This calculation is based on a variety of factors including the number of employees enrolled in the plan. This plan allows for some cash flow benefits while guarantying a maximum premium liability. Actual results may vary from estimates based on the Company’s actual experience at the end of the plan policy periods based on the carrier’s loss predictions and its historical claims data. The Company’s worker’s compensation, auto and general liability insurance are purchased under large deductible programs. The Company’s current per incident deductibles are: worker’s compensation $250,000, auto $500,000 and general liability $100,000. The Company expenses the deductible portion of the individual claims. However, the Company generally does not know the full amount of its exposure to a deductible in connection with any particular claim during the fiscal period in which the claim is incurred and for which it must make an accrual for the deductible expense. The Company makes these accruals based on a combination of the claims development experience of its staff and its insurance companies, and, at year end, the accrual is reviewed and adjusted, in part, based on an independent actuarial review of historical loss data and using certain actuarial assumptions followed in the insurance industry. A high degree of judgment is required in developing these estimates of amounts to be accrued, as well as in connection with the underlying assumptions. In addition, the Company’s assumptions will change as its loss experience is developed. All of these factors have the potential for significantly impacting the amounts the Company has previously reserved in respect of anticipated deductible expenses and the Company may be required in the future to increase or decrease amounts previously accrued. Under the Company’s various insurance programs, it has collective reserves recorded in accrued liabilities of $10.7 million and $7.8 million at December 31, 2009 and 2010, respectively. As of December 31, 2010, in connection with the issuance of our insurance policies, Mobile Mini has provided its various insurance carriers approximately $8.7 million in letters of credit. 76 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. General Litigation The Company is a party to routine claims incidental to its business. Most of these routine claims involve alleged damage to customers’ property while stored in units leased from Mobile Mini and damage alleged to have occurred during delivery and pick-up of containers. The Company carries insurance to protect it against loss from these types of claims, subject to deductibles under the policy. The Company does not believe that any of these incidental claims, individually or in the aggregate, is likely to have a material adverse effect on its business or results of operations. (13) Mergers and Acquisitions: The Company enters new markets in one of three ways i) a new branch start-up, ii) or through acquiring a business consisting of the portable storage assets and related leases of other companies, or iii) by establishing greenfield operational yards which are new start-up locations that do not have all the overhead associated with a fully-staffed new branch start-up. An acquisition generally provides the Company with cash flow which enables the Company to immediately cover the overhead cost at a new branch. On occasion, the Company also purchases portable storage businesses in areas where the Company has existing small branches either as part of multi-market acquisitions or in order to increase the Company’s operating margins at those branches. In 2008, the Company completed the Merger by which MSG became a wholly-owned subsidiary of Mobile Mini, Inc., and also acquired four other portable storage businesses, three through asset purchase agreements and one as a stock purchase. The Merger and other acquisitions were accounted for as the purchase of a business with the purchased assets and assumed liabilities recorded at their estimated fair values of the date of each acquisition. The Company did not enter into any mergers or acquisitions in either 2009 or 2010. (14) Integration, Merger and Restructuring Costs: In connection with the Merger, the Company recorded accruals for costs to be incurred to exit overlapping Mobile Storage Group lease properties, property shut down costs, costs of Mobile Storage Group’s severance agreements, costs for asset verification and for damaged assets. In connection with the Merger, the Company leveraged the combined fleet and restructured the manufacturing operations and reduced overhead and capital expenditures for the lease fleet. In connection with these activities, the Company recorded costs for severance agreements and recorded impairment charges to write down to certain assets previously used in conjunction with the manufacturing operations and inventories. 77 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC.

All of the Company’s branches operate in their local currency and although the Company is exposed to foreign exchange rate fluctuation in other foreign markets where the Company leases and sells the Company’s products, the Company does not believe this will have a significant impact on the Company’s results of operations. Financial results of geographic regions are aggregated into one reportable segment since their operations have similar characteristics. 78 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. Each branch has similar characteristics covering all products leased or sold, including similar products and services, processes for delivering these services, customer base, sales personnel, advertising, yard facilities, general and administrative costs and the method of branch management. Management’s allocation of resources, performance evaluations and operating decisions are not dependent on the mix of a branch’s products. The Company does not attempt to allocate shared revenue nor general, selling and leasing expenses to the different configurations of portable storage and office products for lease and sale. The branch operations include the leasing and sales of portable storage units, portable offices and combination units configured for both storage and office space. The Company leases to businesses and consumers in the general geographic area surrounding each branch. In managing the Company’s business, management focuses on growing leasing revenues, particularly in existing markets where it can take advantage of the operating leverage inherent in its business model, EBITDA and earnings per share. 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; therefore, reportable segment information is the same as contained in the Company’s Consolidated Financial Statements. The tables below represent the Company’s revenues from customers and long-lived assets, consisting of lease fleet and property, plant and equipment.

(17) Selected Consolidated Quarterly Financial Data (unaudited): The following table sets forth certain unaudited selected consolidated financial information for each of the four quarters in the years ended December 31, 2009 and 2010. In management’s opinion, this unaudited consolidated quarterly selected information has been prepared on the same basis as the audited consolidated financial statements and includes all necessary adjustments, consisting only of normal recurring adjustments, which management considers necessary for a fair presentation when read in conjunction with the Consolidated Financial Statements 79 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) MOBILE MINI, INC. and notes. The Company believes these comparisons of consolidated quarterly selected financial data are not necessarily indicative of future performance.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. There were no disagreements with accountants on accounting and financial disclosure matters during the periods reported herein. ITEM 9A. CONTROLS AND PROCEDURES. 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 Annual Report on Form 10-K, the Company’s disclosure controls and procedures, were effective such that the information relating to the Company required to be disclosed in our 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. Report of Management on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the company. Internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; providing reasonable assurance that receipts and expenditures of company assets are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use, or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2010. Our internal control over financial reporting as of December 31, 2010 has been audited by Ernst & Young, LLP, an independent registered public accounting firm, as stated in their report which is included herein. 89 Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders of Mobile Mini, Inc. We have audited Mobile Mini, Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Mobile Mini, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, Mobile Mini, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Mobile Mini, Inc. (and subsidiaries) as of December 31, 2010 and 2009, and the related consolidated statements of income, preferred stock and stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2010 of Mobile Mini, Inc. and our report dated March 1, 2011 expressed an unqualified opinion thereon. Ernst & Young LLP Phoenix, Arizona March 1, 2011 90 Changes in Internal Control Over Financial Reporting Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we conducted an evaluation of any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during our most recently completed fiscal quarter. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that there has not been any change in our internal control over financial reporting during that quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
