CORPORATE PROFILE

Mobile Mini, Inc. is North America’s leading provider of portable storage solutions through its total fleet of over 103,000 portable storage
units and offices. Through a Company-owned network of 49 branches located in 29 states and one Canadian province, the Company imple-
ments a replicable operating strategy of leasing secure, high quality portable storage containers and office units, to offer a diversified product line
and to deliver 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  internal  growth  focus  by  increasing  market  awareness,  product  differentiation,  sales  emphasis,  employee
retention, promotion from within and geographic expansion.

Since it’s founding in 1983, Mobile Mini’s diligent focus on these initiatives has driven the Company’s expansion from one location to a network of 49
locations throughout the United States and Canada. At the same time, this strategic focus has enabled the Company to build a solid financial foundation and
positioned Mobile Mini to continue its pattern of profitable growth.

Message to Our Fellow Shareholders:

As I write this letter reviewing our activities and financial performance in 2004, the best year in Mobile Mini’s history, I
recall last year’s Annual Report in which I pointed to early signs of an upturn in our key business indicators.  At that time, it
was too early to define the promising signals as a bona fide trend, but with the benefit of hindsight, the word upturn was
clearly an understatement.  

All the ingredients for success were in place in 2004 – our strong financial structure, our national branch network, our dif-
ferentiated fleet of portable storage units and offices encompassing a wide range of product sizes and functionality, all backed
by our focused sales and marketing culture.  These elements, combined with skillful execution of our strategy to increase units
on rent, proved to be a winning formula across all geographic regions in our branch network.  Of course, the improvement in
the U.S. economy also factored positively into Mobile Mini’s exceptional operating and financial performance in 2004.

2004 Operating Highlights
▲ Internal growth in leasing revenues (the increase in leasing revenues at branch locations open one year or more, excluding

any growth from acquisitions at those locations) was 16.0%, up from 7.4% in 2003;

▲ Yield (total lease revenues per unit on rent) rose 4.1% compared to 2003 while the average number of units on rent for

2004 was up 12.1% over the prior year;

▲ The average utilization rate was 80.7% compared to 78.7% in 2003; 

▲ The lease fleet grew 12.4%, to over 100,000 units from 89,500 one year earlier;

▲ The number of customers to whom we leased storage units or mobile offices was approximately 75,000, an 11.9% gain

from 67,000 one year earlier.

▲ With the addition of a new branch in Detroit, Michigan, we closed the year with 49 Mobile Mini locations.

Financial Highlights 2004 versus Pro Forma 20031
▲ Total revenues rose 14.9% to $168.3 million from $146.6 million; 

▲ Lease revenues rose 16.6% to $149.9 million from $128.5 million; 

▲ Lease revenues accounted for 89.0% of total revenues as compared to 87.7%;

▲ EBITDA rose 20.1% to $67.3 million from $56.0 million and our EBITDA 

margin rose to 40.0% from 38.2% just one year earlier.

▲ Operating income was up 22.1% to $54.9 million from $44.9 million; 

▲ Net income was $20.7 million, up 18.3% from $17.5 million; and,

▲ Earnings per diluted share increased 15.7% to $1.40 from $1.21. 

Mobile Mini is the nation’s leading
provider of portable storage solutions.

Business Overview

Building a national network of Mobile Mini branches was a high corporate priority between 1998 and 2002.  During those

years, we  increased our number of branches from eight to 46.  This expansion culminated in 2002 with 11 new branches.
Our focus changed during the past two years and strengthening our market position at existing locations became job one.
The success of this strategy and its execution are best measured by our internal growth rate, which in every quarter of 2004
exceeded the comparable period of 2003, rising to 22.2% in the final quarter of 2004.  What equally delighted us was the
fourth quarter 13.6% internal growth rate achieved by our eight oldest and largest branches.  The rising internal growth rate,
utilization rate and yield were the catalysts necessary for the resumption of the superior operating leverage that we can achieve
with our business model.    

The Mobile Mini Business Model

In 1996, Mobile Mini set its sights on becoming a customer service-driven marketing enterprise focused on leasing storage

solutions through our own branch locations.  The effectiveness of this business model over time is quite impressive.  
From 1996 to 2004:
▲ Branch locations increased from 8 in 3 states to 49 in 29 states and one Canadian province;
▲ Our total lease fleet grew from 13,600 units to 100,600 units, for a compound annual growth rate (“CAGR”) of 28.4%; 
▲ Total revenues increased from $42.4 million to $168.3 million, for a CAGR of 18.8%;
▲ Leasing revenues increased from $17.9 million to $149.9 million, for a CAGR of 30.4%;
▲ Lease revenues as a percent of the total revenues increased from 42.1% to 89.0% in 2004; and,
▲ Pro forma operating income increased from $5.4 million to $54.9 million, for a CAGR of 33.5%.

This model requires substantial upfront and continual fixed costs at all locations to install and maintain the infrastructure
necessary to support branch leasing growth.  The key to improving operating margins hinges on our ability to grow the num-
ber of containers on lease at our locations at favorable rental rates.  Invariably, newer branches generally produce lower operat-
ing margins than their more mature counterparts, but as new branches increase containers on lease, they spur growth in lease
revenue and earnings.  

We use the following table to show operating margins and the return on the invested capital at our various branches, sorted
by the year the branches began operations.  The table visibly shows how the profitability of branches has improved once they
are firmly established and how older branches have pro-
duced healthy returns on invested capital.  While newer
locations typically achieve stronger organic growth than the
older locations, with time, they truly make a meaningful
and enduring contribution to our operating margin and
return on invested capital.

While a stronger economy generally works to our advan-

tage, Mobile Mini’s core portable storage leasing business
has some undeniably attractive economic characteristics,
irrespective of the prevailing economic climate, including:
▲ Predictable, recurring revenues from leases, with an aver-

age lease duration of approximately 22 months;

▲ Average monthly lease rates that recoup our current unit

investment within an average of 35 months;

▲ Assets with long useful lives exceeding 25 years, low

maintenance and high residual values; 

▲ Rental rates that are generally not affected by the age of

the portable storage unit; and

▲ 73 % EBITDA margins and approximately 57% pretax

margins on incremental leasing revenue.

Confluence of Sales & Marketing and Product & Customer Diversification 

Increasing the size of the portable storage market in each region where we operate is the engine of our business plan, and we

fuel that engine with complementary sales and marketing programs.  In 2004, we spent $7 million on advertising, primarily
for yellow page and direct mail advertising.  Last year, we mailed approximately 7.5 million product brochures to customers
and prospects.  In addition to marketing, one of our strengths is our commissioned sales force, which is located at each of our
branches.  Our sales force is comprised of more than 300 highly motivated individuals who are equipped for success with our
customized contact management system, and their skills are regularly honed with intensive sales training and sales monitoring
programs.

We have built a broad base of customers who use our 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.  Of the
75,000 or so customers we served in 2004, 60.9% rented a single unit.  Our two largest customers accounted for 4.0% and
0.4% of our leasing revenues, respectively, and our twenty largest customers accounted for approximately 6.5% of our leasing
revenues.  Our customers represent nearly all industries and endeavors, including all kinds and sizes of retailers, construction
companies, medical centers, schools and universities, utilities, distributors, the U.S. military, hotels, restaurants, entertainment
complexes, and consumers.  

While our sales and marketing efforts are intense and highly monitored, the reason we can and do provide storage to so many

customers is because with over 100 different configurations of units, we have the industry’s broadest range of portable storage
products.  Our portable storage units vary in size from five to 48 feet in length and eight to 10 feet in width.  The vast majority
of our products have a proprietary locking system and multiple door options.  In addition, we offer portable storage units with
electrical wiring, shelving and other customized features.  Since we design and manufacture portable storage units as well as
refurbish and modify used ocean-going containers, we are able to differentiate our products from those of our
competition and offer the ideal storage solution to each customer.  

Our product mix includes steel and wooden offices, which are commonly used as first aid, guard/security,
sales and job site offices.  Our offices range in size from small construction offices to deluxe double wide sales
offices.  We also offer our customers a very differentiated all steel security office, which sits directly on the
ground, eliminating expensive stairs, steps and tie downs. This product diversification makes Mobile Mini the
single source for storage and office units.  

We believe that customer service focused locally from each branch is essential to our long term success.  Each
of our branches has its own locally-based management team, sales people, delivery drivers, delivery trucks, serv-
ice crews and rental and sales inventory.  With a local focus, we can leverage our business model nationally and
give our customers immediate, local and personalized service.

While we have a very decentralized operating structure, we utilize our MIS systems and regional managers to
centrally manage our growth, sales training, inventories, prospecting and accounting.  This structure allows us to
maintain our localized sales and marketing culture within an efficient nation-wide enterprise.

Internal Growth & Geographic Expansion

One of our major initiatives in 2004 was to optimize our rental fleet, taking all steps

necessary to ensure that our storage units are in ready-to-rent condition and able to
meet customer demand.  Throughout the year, we relocated available storage and office
units to our branches where demand was close to outpacing supply. This initiative,
which will continue throughout 2005, accounts for some of the gains in our 2004 uti-
lization rate and in return on invested capital. 

As we resume a slightly more aggressive new branch strategy of entering two to four
new markets in 2005, we must again state that our expansion formula is not, nor will it
ever be, a rollup or consolidation strategy.  The vast majority of our rental fleet growth is
internally generated and not dependant upon acquisitions.  Most of our branches were
established by purchasing a small revenue-generating lease fleet in a new market.  In this
scenario, our objective is to forego start-up expenses and begin operations in a new mar-
ket with acquired assets already under lease, and to grow our presence from there.  

When the right lease assets are not available in the right market at the right price, we

have established greenfield branches using our low-cost start-up formula. An example
is  our first new branch of 2005, serving Minneapolis-St. Paul since April 2005.  

Once we enter a new market, we move quickly to enlarge the fleet inventory with
our differentiated products, launch an aggressive advertising and direct marketing cam-
paign, staff the branch with seasoned Mobile Mini personnel and integrate our cus-
tomized management information systems designed to optimize branch productivity.
We have a perfect batting average; all 40 of the branches established between 1998 and
2004 remain open and are doing business.

Storage where you need it.

We have branches in many of our target markets.  None of these markets are mature

and we believe that many have the potential to double and triple in size.  In other
words, we can look forward to many years of strong internal growth from our current
branch network.  That said, we also have a disciplined approach to entering new mar-
kets.  We have identified approximately 50 additional U.S. and Canadian markets where
we believe our business model will work quite well.  These include some of the largest
cities in the country, so we also anticipate many years of geographic expansion.  As
noted above, new market acquisitions and greenfield branches historically depress our
operating and EBITDA margins in the early years, but this effect is much less significant
to our overall results than was the case three or four years ago because Mobile Mini is
today a much larger company.

Balance Sheet Highlights & Spending Plans

We are accomplishing our balance sheet objectives of deleveraging on a funded debt–to-EBITDA basis.  At year-end 2004,

funded debt-to-EBITDA was 4.1 to 1, down from 4.4 to 1 at the close of the third quarter.  Looking ahead, we expect to
continue to grow EBITDA at a faster rate than funded debt.  

At year-end, stockholders’ equity stood at $216.4 million, up 14.3% from $189.3 million when the year started.  Cash flow

from operations of $42.3 million together with borrowings under our line of credit were used to fund our most significant
investment, which was the $76.6 million we spent in 2004 on capital expenditures related to growth (primarily for enlarging
our fleet).  We are fortunate in that we do not have to spend anything on maintenance capital expenditures on our steel stor-
age units and had to spend only $2.5 million on maintenance capital expenditures related to the rest of our business.  Our
maintenance capex is spent primarily on replacing delivery trucks and trailers and not on replacing worn out rental assets.  On
this subject, it is worth noting that at December 31, 2004, the fair market value of our lease fleet was approximately 110.6%
of our lease fleet net book value.  We closed the year with $110.7 million of unused borrowing capacity despite the year’s 16%
internal growth rate, the major expansion of our fleet, our entry into the Detroit market, and the increase in fleet maintenance
and optimization costs, which amounted to 2.9% of lease revenue and was expensed.  Our capital expenditures for 2005 have
been budgeted at between $65 million and $90 million, and are primarily earmarked for lease fleet purchases, but that is sub-
ject to change depending primarily on our internal growth rate and on the number of new locations we enter in 2005.

Outlook for 2005

The favorable trends of 2004 are continuing into the new year.  We continue to experience strong demand for our prod-
ucts, improving rental yields and improving rental fleet utilization. One of the consistent historic patterns in our business, first
quarter return of storage container by retailers following the holiday season, has been minimized in 2005.  In the final quarter
of 2004, we were able to limit short-term holiday rentals because of exceptionally strong demand from our core customer
base, which is comprised of those long-term renters who incorporate our units into their business and/or operations.  Those
units that were placed with retailers for the holidays and then returned in the first quarter are quickly being deployed to other
customers.  While our average lease duration is 22 months, we also have annuity customers who have continually rented our
storage units for as many as 15 years or longer. 

Based upon our projected 19% to 20% internal growth rate, our 2005 guidance for EBITDA is in the range of $84 million

to $85 million and for diluted earnings per share, in the $1.88 to $1.92 range.  

Of Note

Mobile Mini added new investment research from Needham & Company in late 2004 and America’s Growth Capital in
early 2005.  With Deutsche Bank Securities, CIBC World Markets and Sidoti & Co., we now have five firms writing equity
research on our company.  In 2004, Mobile Mini was the subject of feature stories in national business media, including
Investor’s Business Daily (September 20, 2004) and Business Week (October 18, 2004). 

The record year Mobile Mini achieved in 2004 would not have been possible without the dedication and hard work of the

1,556 members of the nationwide Mobile Mini family, and on behalf of the Board of Directors, we thank all of you.  We
hope to continue rewarding our shareholders for their confidence, backed by their investment, in Mobile Mini.  We also
appreciate the support of our suppliers, customers, noteholders and commercial lenders.

Sincerely yours,  

Steven G. Bunger
Chairman, President & Chief Executive Officer

Regarding 2003 Pro Forma Results

1 We define “pro-forma” as operating results excluding non-operating charges.  The non-operating charges that we exclude consist of items such as
expenses associated with material litigation and debt restructuring expense, where these expenses are presented as separate line items on our state-
ment of income for the relevant period.  The table below sets forth our reconciliation of net income and operating income from GAAP to pro
forma for fiscal year ended 2003.

We include a reconciliation of our pro forma results and our actual results in our press releases announcing our operating results.  The reconcilia-
tion of our fiscal 2003 results is set forth in our current report on Form 8-K filed with the Securities and Exchange Commission on February 24,
2004, which is available on our Internet website at http://www.mobilemini.com.

2 EBITDA is defined as net income before interest expense, income taxes, depreciation, amortization and debt restructuring expense.  In comparing
EBITDA from year to year, we typically ignore the effect of what we consider non-recurring events not related to our core business operations to
arrive at adjusted EBITDA.  The only non-recurring events reflected in the adjusted EBITDA over the last several years has been the effect in 2002
and 2003 of our Florida litigation expenses and the effect in 1996 of a restructuring charge for winding down our modular sales division.  We pres-
ent a reconciliation of net income to EBITDA in Item 6, “Selected Financial Data” of our annual report on Form 10-K for the fiscal year ended
December 31, 2004. That form 10-K is included elsewhere herein.

BUSINESS.   

PART I 

Founded in 1983, we believe we are the nation’s largest provider of portable storage solutions through our lease fleet of over 100,000
portable storage and portable office units at December 31, 2004.  We offer a wide range of portable storage products in varying lengths 
and widths with an assortment of differentiated features such as our proprietary security systems, multiple doors, electrical wiring and 
shelving.  At December 31, 2004, we operated through a network of 48 branches located in 28 states and one Canadian province.  Our 
portable units provide secure, accessible temporary storage for a diversified client base of approximately 75,000 customers, including 
large and small retailers, construction companies, medical centers, schools, utilities, distributors, the U.S. military, hotels, restaurants, 
entertainment complexes and households.  Our customers use our products for a wide variety of storage applications, including retail
and  manufacturing  inventory,  construction  materials  and  equipment,  documents  and  records  and  household  goods.    Based  on  an 
independent market study, we believe our customers are engaged in a vast majority of the industries identified in the four-digit SIC 
(Standard Industrial Classification) manual published by the U.S. Bureau of the Census.  For the twelve months ended December 31,
2004, we generated revenues of $168.3 million. 

Since 1996, we have followed a strategy of focusing on leasing rather than selling our portable storage units. We believe this leasing 
model is highly attractive because the vast majority of our fleet consists of steel portable storage units which: 

• 
• 
• 
• 

provide predictable, recurring revenues from leases with an average duration of approximately 22 months; 
have average monthly lease rates that recoup our current unit investment within an average of 35 months; 
have long useful lives exceeding 25 years, low maintenance and high residual values; and 
produce incremental leasing operating margins of approximately 57%. 

Since 1996, we have increased our total lease fleet by over 87,000 units, for a compound annual growth rate, or CAGR, of 28.4%.  As 
a result of our focus on leasing, we have achieved substantial increases in our revenues and profitability.  Our annual leasing revenues 
have  increased  from  $17.9  million  in  1996  to  $149.9  million  in  2004,  representing  a  CAGR  of  30.4%.    In  addition  to  our  leasing 
operations, we sell new and used portable storage units and provide delivery, installation and other ancillary products and services. 

Our  fleet  is  primarily  comprised  of  refurbished  and  customized  steel  portable  storage  containers,  which  were  built  according to the 
standards  developed  by  the  International  Organization  for  Standardization  (“ISO”),  and  other  steel  containers  that  we  manufacture.
We refurbish and customize our purchased ISO containers by adding our proprietary locking and easy opening door systems.  These
assets are characterized by low risk of obsolescence, extreme durability, long useful lives and a history of high value retention.  We 
maintain  our  steel  containers  on  a  regular  basis.    This  maintenance  consists  primarily  of  repainting  units  every  two  to  three  years, 
essentially  keeping  them  in  the  same  condition  as  when  they  entered  our  fleet.    Repair  and  maintenance  expense  for  our  fleet  has
averaged 2.4% 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 offices from our 
lease fleet at an average of 145% of original cost from 1997 to 2004.  Appraisals on our fleet are conducted on a regular basis by an 
outside appraiser selected by our banks, and 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.  Our most recent fair market value appraisal, conducted in March 2004, appraised our fleet at a 
value in excess of net book value.  At December 31, 2004, the fair market value of our lease fleet was approximately 110.6% of our 
lease  fleet  net  book  value.    An  orderly  liquidation  value  appraisal,  on  which  our  borrowings  under  our  revolving  credit  facility  are 
based, was performed in March 2004. At December 31, 2004, the orderly liquidation value of our lease fleet is approximately $357.0
million, which equates to 79.0% of the lease fleet net book value.

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. 

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.  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 local 

2

in nature with only a few national participants.  Historically, portable storage solutions included containers, trailers and roll-off units.  
We believe portable storage containers are achieving increased market share from other options because of an increasing awareness of 
the advantages portable storage provides and growing availability of portable storage products to meet the needs of a diverse range of 
customers.  Portable storage containers provide ground level access, higher security and improved aesthetics compared with portable
storage  alternatives  such  as  trailer  storage  solutions.    Although  there  are  no  published  estimates  of  the  size  of  the  portable  storage 
segment, we believe the size of the segment is expanding due to increasing awareness of the advantages of portable storage. 

Our  products  also  serve  the  mobile  office  industry.    This  industry  provides  mobile  offices  and  other  modular  structures  and  is 
estimated  to  exceed  $2.5  billion  in  revenue  annually.    We  offer  combined  storage/office  and  mobile  offices  in  varying  lengths  and 
widths, with lease terms averaging approximately 20 months. 

We  also  offer  portable  record  storage  units  and  many  of  our  regular  storage  units  are  used  for  document  and  record  storage.    The
documents and records storage industry is experiencing significant growth as businesses continue to generate substantial paper records 
that must be kept for extended periods. 

Our goal is to continue to be the leading national provider of portable storage solutions.  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,  2004,  we  maintained  a  total  fleet  of  both  units  held  for  lease  and  for  sale,  which  was 
approximately 103,000 units, and are the largest provider of portable storage solutions in a majority of our markets.  We believe we are 
creating  brand  awareness  and  the  name  “Mobile  Mini”  is  associated  with  high  quality  portable  storage  products,  superior  customer
service  and  value-added  storage  solutions.    We  have  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 needs. 

Superior, Differentiated Products.  We offer the industry’s broadest range of portable storage products, with many customized features 
that differentiate our products from those of our competition.  We design and manufacture our own portable storage units in addition to 
restoring and modifying used ocean-going containers.  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 five to 48 feet in length and eight to 10 feet in width.  The 10-
foot  wide  units  we  manufacture  provide  40%  more  usable  storage  space  than  the  standard  eight-foot-wide  ocean-going  containers 
offered  by  our  competitors.    The  vast  majority  of  our  products  have  a  proprietary  locking  system  and  multiple  door  options.    In
addition, we offer portable storage units with electrical wiring, shelving and other customized features. 

Geographic  and  Customer  Diversification.    From  our  48  branches,  which  are  located  in  28  states  and  one  Canadian  province,  we 
served  approximately  75,000  customers  from  a  wide  range  of  industries  in  2004.    Our  customers  include  large  and  small  retailers,
construction companies, medical centers, schools, utilities, distributors, the U.S. military, 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  2004,  our  largest  and  our  second-largest  customers  accounted  for  4.0%  and  0.4%  of  our 
leasing revenues, respectively, and our twenty largest customers accounted for approximately 6.5% of our leasing revenues.  During 
2004, approximately 60.9% of our customers rented a single unit.  We believe this diversity also reduces our susceptibility to economic 
downturns in our markets or in any of the industries in which our customers operate.  The fact that our business continued to grow 
during the economic downturn of 2002 and 2003, although at a slower than historic pace, demonstrates a measure of resilience against 
recession in our business model. 

Customer Service Focus.  We believe the portable storage industry is particularly service intensive and essentially local.  Our entire 
organization is focused on providing high levels of customer service, and our salespeople work out of our branch locations to better
understand local market 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  flexible  lease  terms,  security,  convenience,  product  quality,  broad  product  selection  and 
availability, and competitive lease rates.  We conduct on-going training programs for our sales force to assure high levels of customer 
service  and  awareness  of  local  market  competitive  conditions.    Our  customized  management  information  systems  also  increase  our 
responsiveness  to  customer  inquiries  and  enable  us  to  efficiently  monitor  our  sales  force’s  performance.    Due  to  our  orientation
towards customer service, 54.7% of our 2004 leasing revenues were derived from repeat customers.

Sales  and  Marketing  Emphasis.    We  target  a  diverse  customer  base  and,  unlike  most  of  our  competitors,  we  have  developed 
sophisticated  sales  and  marketing  programs  enabling  us  to  expand  market  awareness  of  our  products  and  generate  strong  internal 
growth.  We have over 300 dedicated commissioned salespeople.  Our salespeople are instrumental in leasing our storage products to 
approximately  75,000  customers.    We  assist  our  salespeople  by  providing  them  with  our  highly  customized  contact  management 
system  and  intensive  sales  training  programs.    We  monitor  our  salespersons’  effectiveness  through  our  extensive  sales  monitoring
programs.    Yellow  page  and  direct  mail  advertising  are  integral  parts  of  our  sales  and  marketing  approach.    In  2004,  our  total 
advertising  costs  were  $7.0  million,  and  we  mailed  over  approximately  7.5  million  product  brochures  to  existing  and  prospective
customers.   

Customized Management Information Systems.  We have made substantial investments in our management information systems that 
enable  us  to  optimize  fleet  utilization,  capture  detailed  customer  data,  improve  financial  performance  and  support  our  growth  by
projecting near-term capital needs.  Our management information systems allow us to carefully monitor, on a daily basis, the size, mix, 
utilization  and  lease  rates  of  our  lease  fleet  by  branch.    Our  systems  also  capture  relevant  customer  demographic  and  usage 
information, which we use to target new customers within our existing and new markets.  Our headquarters and each branch are linked 
through a scaleable PC-based wide area network that provides real-time transaction processing and detailed reports on a branch-by-
branch basis.  We have made significant investments to enhance our management information systems during 2004, and we intend to
continue that investment in 2005. 

Business Strategy 

Our business strategy consists of the following:  

Focus on Core Portable Storage Leasing Business.  We focus on growing our core leasing business because it provides predictable, 
recurring revenue and high margins.  We believe that we can generate substantial demand for our portable storage units throughout the 
United States. Our leasing revenues have grown from $17.9 million in 1996 to $149.9 million in 2004, reflecting a CAGR of 30.4%.

Generate Strong Internal Growth.  We focus on increasing the number of portable storage units we lease from our existing branches to 
both new and repeat customers.  Historically, we have been able to generate strong internal growth within our existing markets through 
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.  We define internal growth as growth in lease revenues in markets 
opened for at least a year, excluding any growth arising as a result of additional acquisitions in those markets.  Our internal growth rate 
for  fiscal  years  2000  and  2001  was  22.3%  and  22.2%,  respectively.    During  the  economic  slowdown  in  fiscal  2002  and  2003,  our 
internal  growth  rate  was  7.5%  and  7.4%,  respectively.    In  2004,  as  the  economy  in  many  of  our  markets  started  to  improve,  we 
achieved an internal growth rate that improved as the year progressed, reaching 22.2% in the fourth quarter and averaging 16.0% for 
the year.  In our eight oldest markets, all of which we have operated in for at least nine years, we achieved internal growth rates of 
8.6% in 2004 and 13.6% during the fourth quarter of 2004, demonstrating the growth we can continue to achieve in our most mature
markets.  

Branch Expansion.  We believe we have an attractive geographic expansion opportunity and we have developed a new market entry 
strategy, which we replicate in each new market.  We typically enter a new-market by acquiring the lease fleet assets of a small local 
portable  storage  business  to  minimize  start-up costs and then overlay our business model onto the new branch. Our business model
consists  of  significantly  expanding  the  fleet  inventory  with  our  differentiated  products,  introducing  our  sophisticated  sales  and 
marketing program supported by increased advertising and direct marketing expenditures, adding experienced Mobile Mini personnel
and  implementing  our  customized  management  information  systems.    As  a  result  of  implementing  our  business  model,  our  new 
branches typically achieve very strong organic growth during their first several years.  

4

We  have  identified  many  markets  in  the  United  States  where  we  believe  demand  for  portable  storage  units  is  underdeveloped.  
Typically, these markets are being served by small, local competitors.  In 1998, we began entering new markets through our expansion 
strategy as illustrated in the following table:

During 2003 and 2004 we decided to forego most business acquisition opportunities in order to focus on growing our existing branch 
network, including those branches acquired in previous years. 

Our expansion program and other factors can affect our overall utilization rate.  From 1996 through 2004, our annual utilization levels 
averaged 81.7%, and ranged from a low of 78.7% in 2003 to a high of 89.7% in 1996.  The lower utilization rate in the last few years 
was  primarily  a  result  of  (i)  the  fact  that  many  of  our  acquisitions  have  had  utilization  levels  lower  than  our  historic  average  rates, 
especially  after  we  have  added  our  proprietary  product  to  the  existing  product  mix  at  new  locations,  (ii)  the  fact  that  it  is  easier  to 
maintain a higher utilization rate at a larger branch and we increased the number of small branches in more recent years, and (iii) the 
economic slowdown during 2002 and 2003 in the general economy and in particular the slowdown in the construction sector.  During
2004, we saw a steady recovery in the overall economy and an improvement in the construction sector, which represents approximately 
32% of our leased units.  As the general economy and the non-residential construction industry in our markets continued to recover 
throughout 2004, we repositioned some of our lease fleet units among our branch locations to meet growing demand.  Our utilization 
levels increased throughout the year and averaged 80.7% during 2004.  We entered six markets in 2001, 11 markets in 2002, and only 
one  market  in  both  2003  and  2004.    From  1996  through 2004,  we  grew  our  lease  fleet  from  approximately  13,600  units  to  over 
100,600 units at the end of 2004. 

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, in 1998 we introduced a 10-foot wide storage unit that has proven to be a popular product with our customers. 
In  1999,  we  completed  the  design  of  a  records  storage  unit,  which  provides  highly  secure,  on-site,  easily  accessible  storage.    We 
market this unit as a records storage solution for customers who require easy access close at hand.  In 2000, we added wood mobile
offices as a complementary product to better serve our customers.  In 2001, we redesigned and improved our security locking system, 
making it easier to use, especially in colder climates.  In 2003, we were issued four patents in connection with the new locking system 
design and other improvements made, and we extended the application on the one patent that is still pending.  In 2002, we added a 10-
by-30-foot steel combination storage/office  unit to complement the various other sizes we have in our fleet.  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 design and manufacturing capabilities increase our ability to service our customers’ needs and demand for our portable
storage solutions. 

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 locally by our employee team at each of our branches, including management, sales personnel and yard facility 
employees. Some features of our different products are listed below: 

•  Refurbished  and  Modified  Storage  Units.    We  purchase  used  ocean-going  containers  from  leasing  companies  or  brokers.  
These containers are eight feet wide, 8’6” to 9’6” high and 20, 40 or 45 feet long.  After acquisition, we refurbish and modify
ocean-going containers.  Refurbishment typically involves cleaning, removing rust and dents, repairing floors and sidewalls,

painting,  adding  our  signs  and  installing  new  doors  and  our  proprietary  locking  system.  Modification  typically  involves 
splitting those containers into 5-, 10-, 15-, 20- or 25-foot lengths. 

•  Manufactured Storage Units.  We manufacture steel portable steel storage units for our lease fleet and for sale.  We do this at 
our manufacturing facility in Maricopa, Arizona.  We can manufacture units up to 12 feet wide and 50 feet long and can add 
doors, windows, locks and other customized features.  We now offer a 10-foot-wide unit, which provides 40% more usable 
storage  space  than  a  standard  eight-foot-wide  unit.    Typically,  we  manufacture  “knock-down”  units,  which  we  ship  to  our 
branches.  These units are then assembled by our branches that have assembly capabilities or by third party assemblers.  This 
method of shipment is less expensive than shipping fully assembled storage units. 

• 

Steel  Combination  Mobile  Office  and  Storage/Office  Units.    We  manufacture  steel  combination  storage/office  and  mobile 
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.  We believe our 
office units provide the advantage of ground accessibility for ease of access and high security in an all-steel design.  These 
units  are  equipped  with  electrical  wiring,  heating  and  air  conditioning,  phone  jacks,  carpet  or  tile,  proprietary  doors  and 
windows with security bars. 

•  Wood Mobile Office Units.  We added wood office units to our product line in 2000.  We purchase these units, which range 
from eight to 24 feet in width and 20 to 60 feet in length, 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. 

•  Records Storage Units.  We market and manufacture 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 product is a cost-effective alternative to mass warehouse storage, with a high level of fire
and water damage protection. 

•  Van Trailers and 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 
manufactured storage products that are inferior to standard containers.  It is our goal to dispose of these sub-standard units 
from  our  fleet  either  as  their  initial  rental  period  ends  or  within  a  few  years.    We  do  not  refurbish  these  products.    See 
“Product Lives and Durability — Van Trailers and Other Non-Core Storage Products.” 

We  purchase  used  ocean-going  containers  and  refurbish  and  modify  them  at  our  manufacturing  facility  in  Arizona  and  at  our  other
branch locations.  At certain branches, we also contract with third parties to refurbish and modify our units.   We manufacture new 
portable storage units at our Arizona facility.  We believe we are able to purchase used ocean-going containers at competitive prices 
because of our volume purchasing power.  The used ocean-going containers we purchase are typically about eight to 12 years old.  We 
believe our steel portable storage units, steel offices, and wood modular offices have estimated useful lives of 25 years, 25 years, and 
20 years, respectively, from the date we build or acquire and refurbish them, with residual values of our per unit investment ranging 
from 50% for our mobile offices to 62.5% for our core steel products.  Van trailers, which comprised less than 1.0% of the gross book 
value of our lease fleet at  December 31, 2004, are depreciated over seven years to a 20% residual value.  For the past three full fiscal 
years, our cost to repair and maintain our lease fleet units averaged approximately 2.4% of our lease revenues.  Repainting the outside 
of storage units is the most frequent maintenance item. 

Product Lives and Durability 

Core Portable Storage Products.  Most of our fleet is comprised of refurbished and customized ISO containers, manufactured steel 
containers and record storage units, along with our combined storage/office and mobile office units.  These products are built to last a 
long period of time with proper maintenance. 

We  generally  purchase  used  ISO  containers  when  they  are  eight  to  12  years  old,  a  time  at  which  their  useful  life  as  ocean-going
shipping containers is over according to the standards promulgated by the International Organization for Standardization.  Because we 
do  not  have  the  same  stacking  and  strength  requirements  as  apply  in  the  ocean-going  shipping  industry,  we  have  no  need  for  these
containers  to  meet  ISO  standards.    We  purchase  these  containers  in  large  quantities,  truck  them to our locations, refurbish them by 

6

removing  any  rust,  painting  them  with  a rust inhibiting paint, adding our locking system and further customizing them, typically by 
adding our proprietary, easy opening door system and our proprietary locking system. 

We  maintain  our  steel  containers  on  a  regular  basis  by  painting  them  on  average  every  two  to  three  years,  removing  rust,  and 
occasionally  replacing  the  wooden  floor  or  a  rusted  panel.    This  periodic  maintenance  keeps  the  container  in  essentially  the  same 
condition as after we initially refurbished it. 

Our revolving credit agreement lenders have our containers appraised on a periodic basis, and the appraiser does not differentiate value 
based upon the age of the container or the length of time it has been in our fleet.  Our manufactured containers and steel offices are not 
built to ISO standards, but are built in a similar manner so that, like the ISO containers, they will maintain their utility and value as 
long as they are maintained in accordance with our maintenance program.  As with our refurbished and customized ISO containers, our 
lenders’ appraiser does not differentiate the value of manufactured units based upon the age of the unit.  Our most recent fair market 
value appraisal appraised our fleet at a value in excess of net book value.  At  December 31, 2004, the net book value of our fleet was 
approximately $451.8 million. 

Approximately 10.6% of our 2004 revenue was derived from sales of portable storage and mobile office units.  Because the containers 
in  the  lease fleet do not significantly depreciate in value, we have no 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  unrefurbished  and  refurbished  containers  that  we  had  recently  acquired  but  not  yet  leased.    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  increase  for  containers  in  the  lease  fleet  for  greater  lengths  of  time  prior  to  sale,  because 
although these units have been depreciated, based upon a 25 year useful life and 62.5% residual value (1.5% per year), in most cases 
fair value may not decline by nearly that amount due to the nature of the assets and our stringent maintenance policy.   

The following table shows the gross margin on containers and steel offices sold from inventory (which we call our sales fleet) and from 
our lease fleet from 1997 through 2004 based on the length of time in the lease fleet.

(1)  “Original cost” for purposes of this table includes (i) the price we paid for the unit plus (ii) the cost of our manufacturing, which 
includes both the cost of customizing units and refurbishment costs incurred, plus (iii) the freight charges to our branch where the 
unit is first placed in service. For manufactured units, cost includes our manufacturing cost and the freight charges to the branch 
location. 

(2)  Includes sales of unrefurbished ISO containers.  

Because steel storage containers 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.  To a 
degree, competition, market conditions and other factors can influence our leasing rates.

The following chart shows, for containers that have been in our lease fleet for various periods of time, the average monthly lease rate 
that we currently receive for various types of containers.  We have added our 10 foot wide containers and security offices to the fleet 
only  in  the  last  several  years  and  those  types  of  units  are  not  included  in  this  chart.    This  chart  includes  the  eight  major  types  of 
containers in the fleet for at least 10 years (we have been in business for over 21 years), and specific details of such type of unit are not 
provided due to competitive considerations.

We believe fluctuations in rental rates based on container age are  primarily a function of the location of the branch from which the 
container  was  leased  rather  than  age  of  the  container.    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: 

• 
• 
• 
• 
• 

results of our lenders’ independent appraisal of our lease fleet; 
practices of the larger competitors in our industry;  
our experience concerning useful life of the units; 
profit margins we are achieving on sales of depreciated units; and 
lease rates we obtain on older units.  

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 are depreciated down to their estimated residual values.  In 2004, some of our steel units were in our fleet longer 
than  20  years  and  we  modified  our  depreciation  policy  on  our  steel  units  to  an  estimated  useful  life  of  25  years  with  an  estimated 
residual value of 62.5% which effectively resulted in continual depreciation on these containers at the same annual rate as our previous 
depreciation policy of 20 year life and 70% residual value.  Wood mobile office units are depreciated over 20 years down to a 50% 
residual value.  Van trailers, which are a small part of our fleet, are depreciated over 7 years to a 20% residual value.  Van trailers are 
only added to the fleet in connection with acquisitions of portable storage businesses.

Wood Mobile Office Units.  We began adding wood mobile office units to the lease fleet in 2000 as a complement to our core portable 
storage  products.    At  December  31,  2004,  we  had  nearly  4,800  of  these  units  at  an  average  original  book  value  of  approximately 
$18,200 per unit.  These units are manufactured by third parties and are very similar to the units in the lease fleets of other mobile 
office rental companies.  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 2004, our wood mobile offices were all less than five years old.  These units 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 four years. 

Additionally,  the  operating  margins  on  mobile  offices  are  lower  than  the  margins  on  portable  storage,  and  because  we  have  added
minimum inventories of these units to most of our branches (initially resulting in lower utilization rates), the addition of mobile offices 
has  reduced  our  overall  return  on  invested  capital.    However,  these  mobile  offices  are  rented  using  our  existing  infrastructure  and 
therefore provide incremental returns far in excess of our fixed expenses.  This adds to our overall profitability and operating margins. 

Van Trailers and Other Non-Core Storage Products.  At December 31, 2004, van trailers made up less than 1.0% of the gross 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 are sub-standard compared to our core steel container storage product.  We attempt to purge most 
of these inferior 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 refurbish these products and instead resell them. 

Van trailers are initially manufactured to be attached to trucks to move merchandise in interstate commerce.  The initial cost of these 
units  can  be  $18,000  or  more.    They  are  leased  to,  or  purchased  by,  cross  country  truckers  and  other  companies  involved  in  cross
country  transportation  of  merchandise.    They  are  made  of  light  weight  material  in  order  to  make  them  ideal  for  transport  and  have 
wheels and brakes.  They are typically made of aluminum, but have steel base frames to maintain some structural integrity.  Because of 
their  light  weight,  moving  parts,  the  heavy  loads  they  carry  and  the  wear  and  tear  involved  in  hundreds  of  thousands  of  miles  of
transport,  these  units  depreciate  quite  rapidly.    This  business  and  the  cartage  business  described  below  are  also  very  economically 
cyclical. 

Once  van  trailers  become  too  old  to  use  in  interstate  commerce  without  frequent  maintenance  and  downtime,  they  are  sold  to 
companies that use them as “cartage trailers.”  At this point, they may have a depreciated cost of approximately $5,000.  As cartage 
trailers, they are used to move loads of merchandise much shorter distances and may be used to store goods for some period of time 
and then to move them from one part of a facility or a city to another part. They continue to depreciate quite rapidly until they reach 
the point where they are not considered safe or cost effective to move loaded with merchandise. 

At this point, near the end of the life cycle of a van trailer, it may be used for storage.  Unlike a storage container, however, van trailers 
are much less secure, can fairly easily be stolen (as they are on wheels) and are unsightly.  Most importantly, they are not ground level 
and, under the Occupational Safety and Health Administration (OSHA) regulations, must be attached to approved stairs or ramps to
prevent accidents when they are accessed. 

A large part of our leasing effort involves demonstrating to our customers the superiority of our containers to van trailers.  Mobile Mini 
has found that when it markets steel storage containers against storage van trailers, customers recognize the superiority of containers. 
As a result, we believe that eventually the use of van trailers will primarily be limited to dock height storage and to customers who 
must frequently move storage units. 

The  average  initial  unit  value  given  to  the  van  trailers  we  have  purchased  in  acquisitions  is  approximately  $1,550  (excluding 
refrigerated units which are valued higher), and we depreciate these units over seven years down to a 20% residual value. As noted 
above,  we  sell  these  units  as  soon  as  practicable.    During  2003  and  2004,  we  disposed  of  over  300  and  almost  600  van  trailers, 
respectively, representing approximately 10% and 20% of our van trailer fleet, respectively.

Lease Fleet Configuration 

Our  lease  fleet  is  comprised  of  over  100  different  configurations  of  units.    Throughout  the  year  we  add  units  to  our  fleet  through 
purchases of used ISO containers and containers obtained through acquisitions, both of which we refurbish and customize.  We also 
purchase  new  manufactured  mobile  offices  in  various  configurations  and  sizes,  and  manufacture  our  own  custom  steel  units.    Our 
initial cost basis of an ISO container includes the purchase price from the seller, the cost of refurbishment, which can include removing 
rust and dents, repairing floors, sidewalls and ceilings, painting, signage, installing new doors, seals and a locking system.  Additional 
modification  may  involve  the  splitting  of  a  unit  to  create  several  smaller  units  and  adding  customized  features.    The  restoring  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 proprietary locking system and sometimes we add custom features.  We also will sell units from our 
lease fleet to our customers. 

The  table  below  outlines  those  transactions  that  effectively  increased  the  net  asset  value  of  our  lease  fleet  from  $382.8  million  at 
December 31, 2003 to $451.8 million at December 31, 2004:

Branch Operations 

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 units to our customers.  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 storage of units under lease at the branch 
(“on-site storage”).  We own our branch locations in Dallas, Texas, Oklahoma City, Oklahoma and a portion of our Phoenix, Arizona 
location.  The rest of our branch locations are leased.  The following table shows information about our branches:

Each branch has a branch manager who has overall supervisory responsibility for all activities of the branch.  Branch managers report 
to one of our twelve regional managers.  Our regional managers, in turn, report to one of our three senior vice presidents.  Incentive 
bonuses are a substantial portion of the compensation for these senior vice presidents, branch and regional managers. 

Each branch has its own sales force 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 three high to maximize usable ground area.  Our larger branches also have a 
fleet  maintenance  department  to  maintain  the  branch’s  trucks,  forklifts  and  other  equipment.    Our  smaller  branches  perform 
preventative maintenance tasks and outsource major repairs. 

Sales and Marketing 

We have over 300 dedicated sales people at our branches and 17 people in sales management at our headquarters and other locations
that  conduct  sales  and  marketing  on  a  full-time  basis.    We  believe  that  by  locating  most  of  our  sales  and  marketing  staff  in  our
branches, we can better understand the portable storage needs of our customers and provide high levels of customer service.  Our sales 
force handles 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 cold calls.  We have on-going 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  management  information  system.    This 
enables the sales and marketing team to share leads and other information and permits the headquarters staff to monitor and review 
sales  and  leasing  productivity  on  a  branch-by-branch  basis.    Our  sales  and  marketing  employees  are  compensated  primarily  on  a 
commission basis.

Our nationwide presence 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  multi-regional customers needs through our National Account
Program,  which simplifies the procurement, rental and billing process for those customers.  Approximately 550 customers 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 advertise our products in the yellow pages and use a targeted direct mail program.  In 2004, we mailed over 7.5 million product 
brochures to existing and prospective customers.  These brochures describe our products and features and highlight the advantages of 
portable storage.  Our total advertising costs were approximately $7.0 million in 2004, $6.9 million in 2003, and $6.2 million in 2002. 

Customers 

During  2004,  approximately  75,000  customers  leased  our  portable  storage,  combination  storage/office  and  mobile  office  units, 
compared to approximately 67,000 in 2003.  Our customer base is diverse and consists of businesses in a broad range of industries.  
Our largest single leasing customer accounted for 4.0% and 4.9% of our leasing revenues in 2004 and 2003, respectively.  Our next 
largest customer accounted for less than 0.4% and 0.5% of our leasing revenues in 2004 and 2003, respectively.  Our twenty largest 
customers combined accounted for approximately 6.5% of our lease revenues in 2004 and approximately 7.4% of our lease revenues in 
2003.  Approximately 60.9% of our customers rented a single unit during 2004. 

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 at December 31,
2004 of our customers and how they use our portable storage, combination storage/office and mobile office units:

Manufacturing 

We  build  new  steel  portable  storage  units,  steel  mobile  offices  and  other  custom-designed  steel  structures  as  well  as refurbish used 
ocean going containers at our Maricopa, Arizona manufacturing plant.  We also refurbish used ocean-going containers at this plant and 
at our branch locations.  Our manufacturing capabilities allow us to differentiate our products from our competitors and enable us to 
provide  a  broader  product  selection  to  our  customers.  Our  manufacturing  process  includes  cutting,  shaping  and  welding  raw  steel,
installing  customized  features  and  painting  the  newly  constructed  units.    Typically,  we  manufacture  “knock-down”  units,  which  we
ship to our branches.  These units are then assembled by our branches that have assembly capabilities or third party assemblers.  We 
can ship up to twelve “knock-down” 20-foot containers on a single flat-bed trailer.  By comparison, only two or three assembled 20-
foot  ocean-going  containers  can  be  shipped  on  a  flat-bed  trailer.    This  reduces  our  cost  of  transporting  units  to  our  branches  and 
permits us to economically ship our manufactured units to any city in the continental United States or Canada.  At December 31, 2004, 
we had about 178 manufacturing workers at our Maricopa facility, and an additional 329 workers who participate in manufacturing and 
repair activities in our branch facilities.  We believe we can expand the capacity of our Maricopa facility at a relatively low cost, and 
that numerous third parties have the facilities needed to perform refurbishment and assembly services for us on a contract basis. 

We purchase raw materials such as steel, vinyl, wood, glass and paint, which we use in our manufacturing and restoring operations.  
We typically buy these raw materials on a purchase order basis.  We do not have long-term contracts with vendors for the supply of 
any raw materials. 

Our manufacturing capacity protects us to some extent from shortages of and price increases for used ocean-going containers.  Used 
ocean-going containers vary in availability and price from time to time based on market conditions.  Should the price of used ocean-
going containers increase substantially, or should they become temporarily unavailable, we can increase our manufacturing volume and 
reduce the number of used steel containers we buy and refurbish. 

Vehicles 

At December 31, 2004, we had a fleet of nearly 400 delivery trucks, of which approximately 300 were owned and approximately 100
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. 

Management Information Systems  

We use a customized management information system in an effort to optimize lease fleet utilization and the effectiveness of our sales 
and marketing.  This system consists of a wide-area network that connects our headquarters and all of our branches.  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 as well as monthly profit and loss statements on a consolidated
and branch basis.  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 system daily at the branch 
level and verified through monthly physical inventories by branch or corporate employees.  Branch salespeople also use the system to 
track customer leads and other sales data, including information about current and prospective customers.  We have made significant 
investments to enhance our management information systems during 2004, and we intend to continue that investment in 2005. 

Lease Terms 

Based  on  the  composition  of  our  leases  at  the  end  of  2004,  our  steel  portable  storage  unit  leases  have  an  average  initial  term  of 
approximately 10 months and provide for the lease to continue at the same rental rate on a month-to-month basis until the customer 
cancels the lease.  The average duration of these leases has been 22 months and the average monthly rental rate for units on lease was 
$100  during  2004.    Most  of  our  steel  portable  storage  units  rent  for  approximately  $50  to  over  $270  per  month.    Our  van  trailers
normally lease for substantially lower amounts than our portable storage units.  Our combination storage/office and mobile office units 
typically have a scheduled initial lease term of approximately 13 months and the average duration of these leases has been 20 months.  
Our combination storage/office and mobile office units typically rent for $100 to over $1,100 per month.  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 
some of this liability.  This provides us with an additional source of recurring revenue. The customer’s possessions stored within the 
portable storage unit are the responsibility of the customer.

Competition 

We face competition from several local companies and usually one or two regional or 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 compete with conventional fixed 
self-storage  facilities  to  a  lesser  extent.    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 Mobile 
Storage  Group  and  a  number  of  smaller  local  competitors.    In  the  mobile  office  business,  we  typically  compete  with  GE  Capital 
Modular Space, Williams Scotsman and other national, regional and local companies.

Cautionary Factors That May Affect Future Operating Results 

Our  discussion  and  analysis  in  this  report,  in  other  reports  that  we  file  with  the  Securities  and  Exchange  Commission,  in  our  press 
releases and in public statements of our officers and corporate spokespersons contain forward-looking statements.  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 “anticipate,” “estimate,” “expect,” “intend,” “plan,” “believe” 
and  other  words  of  similar  meaning  in  connection  with  discussion  of  future  operating  or  financial  performance.    These  include 
statements relating to future actions, acquisition and growth strategy, future performance or results of current and anticipated products, 
sales efforts, expenses, the outcome of contingencies such as legal proceedings and financial results.  

Forward-looking statements may turn out to be wrong.  They can be affected by inaccurate assumptions or by known or unknown risks
and uncertainties.  Many factors mentioned in this report, for example, the availability to Mobile Mini of additional equity and debt 
financing  that  could  be  needed  to  continue  to  achieve  growth  rates  similar  to  those  of  the  last  several  years,  will  be  important  in 
determining  future  results.    No  forward-looking  statement  can  be  guaranteed,  and  actual  results  may  vary  materially  from  those 
anticipated in any forward-looking statement. 

Mobile  Mini  undertakes  no  obligation  to  update  any  forward-looking  statement.    We  provide  the  following  discussion  of  risks  and
uncertainties relevant to our business.  These are factors that we think could cause our actual results to differ materially from expected 
and historical results.  Mobile Mini could also be adversely affected by other factors besides those listed here. 

15

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.  In June 2003, we issued $150.0
million  in  aggregate  principal  amount  of  9.5%  Senior  Notes,  due  2013.    Under  our  revolving  credit  facility,  we  can  borrow  up  to
$250.0  million  on  a  revolving  loan  basis,  which  means  that  amounts  repaid  may  be  reborrowed.    As  of  March  1,  2005,  we  had 
outstanding borrowings of approximately $134.3 million and letters of credit of approximately $3.3 million under the credit facility, 
leaving  approximately  $115.7  million,  available  for  further  borrowing,  of  which  approximately  $102.3  million  was  immediately 
available computed under the most restrictive covenant contained in the revolving credit facility.  Our substantial indebtedness could 
have important consequences.  For example, it could:   

• 

require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, which could 
reduce  the  availability  of  our  cash  flow  to fund future working capital, capital expenditures, acquisitions and other general 
corporate purposes; 

•  make it more difficult for us to satisfy our obligations with respect to our Senior Notes; 

• 

• 

• 

• 

• 

• 

• 

expose us to the risk of increased interest rates, as certain of our borrowings will be at variable rates of interest; 

require us to sell assets to reduce indebtedness or influence our decisions about whether to do so; 

increase our vulnerability to general adverse economic and industry conditions; 

limit our flexibility in planning for, or reacting to, changes in our business and our industry; 

restrict us from making strategic acquisitions or pursuing business opportunities; 

place us at a competitive disadvantage compared to our competitors that have relatively less indebtedness; and 

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. 

Subject to the restrictions in our revolving credit facility and the indenture governing our Senior Notes, we and our subsidiaries may 
incur significant additional indebtedness.  Although the terms of the revolving credit facility and the indenture contain restrictions on 
the  incurrence  of  additional  indebtedness, these restrictions are subject to a number of qualifications and exceptions, and additional 
indebtedness incurred in compliance with these restrictions could be substantial.  If new debt is added to our current debt levels, the 
related risks that we now face could increase. 

Covenants in our debt instruments restrict or prohibit our ability to engage in or enter into a variety of transactions. 

The indenture governing our Senior Notes and our  revolving credit facility agreement contain various restrictive covenants that  limit 
our discretion in operating our business.  In particular, these agreements limit our ability to, among other things: 

•  make restricted payments (including paying dividends on, limitations on redeeming or repurchasing our capital stock); 

• 

issue preferred stock of subsidiaries;  

•  make certain investments or acquisitions;  

• 

• 

create liens on our assets to secure debt;  

engage in transactions with affiliates;  

•  merge, consolidate or transfer substantially all of our assets; and 

• 

transfer and sell assets.  

16

In  addition,  our  revolving  credit  facility  requires  us  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  indenture  governing  the  Senior  Notes,  and the restated 
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. 

Our planned growth strains our management resources, which could disrupt our development of our new branch locations. 

Our  future  performance  will  depend  in  large  part  on  our  ability  to  manage  our  planned  growth.    Our  growth  could  strain  our 
management, human and other resources.  To successfully manage this growth, we must continue to add managers and employees and 
improve our operating, financial and other internal procedures and controls.  We also must effectively motivate, train and manage our 
employees.  If we do not manage our growth effectively, some of our new branches and acquisitions may lose money or fail, and we
may have to close unprofitable locations. Closing a branch would likely result in additional expenses that would cause our operating 
results to suffer. 

We may need additional debt or equity to sustain our growth, but we do not have commitments for such funds.  

We finance our growth through a combination of borrowings, cash flow from operations, and equity financing.  Our ability to continue 
growing at the pace we have historically grown will depend in part on our ability to obtain either additional debt or equity financing.  
The terms on which debt and equity financing is available to us varies from time to time and is influenced by our performance and by 
external factors, such as the economy generally and developments  in the market, that are beyond our control.  Also, additional debt 
financing or the sale of additional equity securities may cause the market price of our common stock to decline which will make it less 
likely that we will pursue any equity financing.  If we are unable to obtain additional debt or equity financing on acceptable terms, we 
may have to curtail our growth by delaying new branch openings, or, under certain circumstances, lease fleet expansion. 

A slowdown in the economy could reduce demand from some of our customers, which could result in lower demand for our 
products. 

At  the  end  of  2004  and  2003,  customers  in  the  construction  industry  accounted  for  approximately  32%  of  our  leased  units.    This 
industry tends to be cyclical and particularly susceptible to slowdowns in the overall economy. In 2002 and 2003 this industry sector 
suffered  a  sustained  economic  slowdown  which  resulted  in  much slower growth in demand for leases and sales of our products.  If
another sustained economic slowdown in this sector were to occur, it is likely that we would again experience less demand for leases 
and sales of our products.  If we do, our results of operations may decline, and we may decide to slow the pace of our planned lease 
fleet growth and new branch expansion.  Our internal growth rate slowed to 7.5% in 2002 and 7.4% in 2003 due to a slowdown in the 
economy,  particularly  in  this  sector.    We  attribute  a  significant  portion  of  the  decrease  in  our  internal  growth rate during 2002 and 
2003 to a recession during those years that had a prolonged effect on the construction industry. 

The supply and price of used ocean-going containers fluctuates, and this can affect our pricing, our ability to grow, and the 
amount we can borrow under our credit facility. 

We purchase, refurbish and modify used ocean-going containers in order to expand our lease fleet.  The availability of these containers 
depends  in  part  on  the  level  of  international  trade  and  overall  demand  for  containers  in  the  ocean  cargo  shipping  business.    When 
international  shipping  increases,  the  availability  of  used  ocean-going  containers  for  sale  often  decreases,  and  the  price  of  available 
containers increases.  Conversely, an oversupply of used ocean-going containers may cause container prices to fall.  Our 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.  This 
would cause our revenues and our earnings to decline. 

17

Ours  is  not  the  only type of business that purchases used ocean-going containers.  Various freight transportation companies, freight 
forwarders and commercial and retail storage companies purchase used ocean-going containers.  Some of these companies have greater
financial resources than we do.  As a result, if the number of available containers for sale decreases, these competitors may be able to 
absorb an increase in the cost of containers, while we could not.  If used ocean-going 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. 

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,  we  cannot  borrow  as  much.    During  2004,  the  price  of  used  ocean-going  containers 
increased and the availability of these units decreased, and if this trend continues we may be unable to add as many units to our fleet as 
we  would  like.    At  the  same  time,  the  increase  in  steel  prices  and  other  raw  materials  has  increased  our  cost  to  manufacture  new
containers. If this trend continues, we may not manufacture as many new units as during recent periods, and we may narrow the mix of 
manufactured  products  we  offer  at  our  branches.  Conversely,  if  steel  prices  or  the  value  of  containers  were  to  rapidly  fall,  those 
occurrences might adversely affect the value of our lease fleet.  We are required to satisfy several covenants with our lenders that are 
affected  by  changes  in  the  value of our lease fleet.  We would breach some of these covenants if the value of our lease fleet drops 
below specified levels.  If this happened, we could not borrow the amounts we would need to expand our business, and we could be
forced to liquidate a portion of our existing fleet. 

The supply and cost of raw materials we use in manufacturing fluctuates and could increase our operating costs. 

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, such 
as have been experienced in 2004, are 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 restrict the use of our storage 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 in some of our markets do 
not  allow  some  of  our  customers  to  keep  portable  storage  units  on  their  properties  or  do  not  permit  portable  storage  units  unless
located  out  of  sight  from  the  street.    If  local  zoning  laws  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. 

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. 

18

Future  changes  in  financial  accounting  standards  may  cause  lower  than  expected  operating  results  and  affect  our  reported 
results of operations. 

Changes  in  accounting  standards  may  have  a  significant  effect  on  our  reported  results  and  may  affect  our  reporting  of  transactions 
completed before the change becomes effective.  New pronouncements and varying interpretations of pronouncements have occurred 
and may occur in the future.  Changes to existing standards or current practices may adversely affect our reported financial results.   

We depend on a few key management persons. 

We are substantially dependent on the personal efforts and abilities of Steven G. Bunger, our Chairman, President and Chief Executive 
Officer, and Lawrence Trachtenberg, our Executive Vice President and Chief Financial Officer.  The loss of either of these officers or 
our other key management persons could harm our business and prospects for growth. 

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 National Market.  The market price of our common stock is likely to be affected by: 

• 
• 
• 
• 
• 
• 

changes in general conditions in the economy, geo political or the financial markets;  
variations in our quarterly operating results;  
changes in financial estimates by securities analysts;  
other developments affecting us, our industry, customers or competitors;  
the operating and stock price performance of companies that investors deem comparable to us; and 
the number of shares available for resale in the public markets under applicable securities laws. 

ITEM 2.  

PROPERTIES. 

We own our branch locations in Dallas, Texas, Oklahoma City, Oklahoma and a portion of our Phoenix, Arizona location.  We lease
all of our other branch locations.  All of our major leased properties have remaining lease terms of at least 2 years, and we believe that 
satisfactory alternative properties can be found in all of our markets if necessary. 

We own our manufacturing facility in Maricopa, Arizona, approximately 30 miles south of Phoenix.  This facility is 13 years old and is 
on  approximately  45  acres.    The  facility  includes  nine  manufacturing  buildings,  totaling  approximately  166,600  square  feet.  These 
buildings house our manufacturing, assembly, restoring, painting and vehicle maintenance operations. 

We lease our corporate and administrative offices in Tempe, Arizona.  These offices have 25,000 square feet of space.  The lease term 
is through August 2008.

ITEM 3.   LEGAL PROCEEDINGS.   

We are party from time to time to various claims and lawsuits which arise in the ordinary course of business.  Although the specific 
allegations  in  the  lawsuits  differ,  most  of  them  involve  claims  pertaining  to  goods  allegedly  damaged  while  stored  in  one  of  our
containers.    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. 

ITEM 4.  

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. 

No matters were submitted to a vote of our security holders during the quarter ended December 31, 2004.

We had approximately 110 holders of record of our common stock on February 16, 2005, and we estimate that we have more than 
2,000 beneficial owners of our common stock. 

Mobile Mini has not paid cash dividends on its common stock and does not expect to do so in the foreseeable future, as it intends to 
retain  all  earnings  to  provide  funds  for  the  operation  and  expansion  of  its  business.    Our  revolving  credit  agreement  precludes  the 
payment of cash dividends on our stock without the consent of our lenders.  

Sales of Unregistered Securities; Repurchases of Securities 

We did not make any sales of unregistered securities during 2004, nor did we repurchase any of our outstanding securities during the 
three months ended December 31, 2004.  

Equity Compensation Plan Information  

Information  regarding  Mobile  Mini’s  equity  compensation  plans,  including  both  stockholder  approved  plans  and  non-stockholder 
approved  plans,  is  set  forth  in  the  section  entitled  “Equity  Compensation  Plan  Information”  in  Mobile  Mini’s  Notice  of  Annual

(1)  EBITDA  is  defined  as  net  income  before  interest  expense,  income  taxes,  depreciation,  amortization,  and  debt  restructuring 
expense.  We present EBITDA because we believe it provides useful information regarding our liquidity and financial condition 
and  because  management  uses  this  measure,  adjusted  for  certain  charges  not  related  to  core  operations,  in  evaluating  the 
performance of the business.  The only such charge during the time periods presented in the table is Florida litigation expenses
which we incurred in 2002 and 2003.  See Item 7. – Management’s Discussion and Analysis of Financial Condition and Results of 
Operations.  EBITDA should not be considered in isolation or 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  United  States  or  as  a 
measure of our profitability or liquidity.  EBITDA may not be comparable to similar titled measure presented by other companies.

(2)  EBITDA margin is calculated as EBITDA divided by total revenues expressed as a percentage.

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 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  1,  “Description  of  Business  -Cautionary 
Factors that May Affect Future Operating Results.” 

Overview  

General

In 1996, we initiated a strategy of focusing on leasing rather than selling our portable storage units.  As a result of this change, leasing 
revenues  as  a  percentage  of  our  total  revenues  increased  steadily  from  42.1%  in  1996  to  89.0%  in  2004.    The  number  of  portable 
storage and combination storage/office and mobile office units in our lease fleet increased from 13,604 at the end of 1996 to 100,629
at the end of 2004, representing a compounded annual growth rate, or CAGR, of 28.4%. 

We  derive  most of our revenues from the leasing of portable storage containers and portable offices.  The average contracted lease 
term at lease inception is approximately 10 months for portable storage units and approximately 13 months for portable offices.  After 
the  expiration  of  the  contracted  lease  term,  units  continue  on  lease  on  a  month-to-month  basis.    In  2004,  the  over-all  lease  term 
averaged 22 months for portable storage units and 20 months for portable offices.  As a result of these long average lease terms, our 
leasing  business  tends  to  provide  us  with  a  recurring  revenue  stream  and minimizes fluctuations in revenues.  However, there is no 
assurance that we will maintain such lengthy overall lease terms. 

In addition to our leasing business, we also sell portable storage containers and occasionally we sell portable office units.  Since 1996, 
when  we  changed  our  focus  to  leasing,  our  sales  revenues  as  a  percentage  of  total  revenues  has  decreased  from  55.7%  in  1996  to 
10.6% in 2004. 

Over the last seven years, Mobile Mini has grown both through internally generated growth and acquisitions which we use to gain a 
presence in new markets.  Typically, we enter a new market through the acquisition of the business of a smaller local competitor and 
then apply our business model, which is usually much more customer service and marketing focused than the business we are buying or 
its competitors in the market.  If we cannot find a desirable acquisition opportunity in a market we wish to enter, we establish a new 
location from the ground up.  As a result, a new branch location will typically 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 branch, we take 
advantage  of  operating  efficiencies  to  improve  operating  margins  at  the  branch  and  typically  reach  company  average  levels  after
several  years.    When  we  enter  a  new  market,  we  incur  certain  costs  in  developing  an  infrastructure.    For  example,  advertising  and 
marketing costs will be incurred and certain minimum staffing levels and certain minimum levels of 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 generate high margins on incremental lease revenues.  Therefore, each additional unit put on lease  in excess of the 
break even level, contributes significantly to profitability.  Conversely, additional fixed expenses that we incur require us to achieve 
additional revenue as compared to the prior period to cover the additional expense.  As a result of these dynamics, from 2000 through 
2003, as we were adding costs related to entering many new markets, there was downward pressure on our overall operating margins.  
In 2004, the second year in a row in which we entered only one new market, this downward pressure abated.   

Among the external factors we examine to determine the direction of our business is the level of non-residential construction activity, 
especially in areas of the country where we have a significant presence.  Construction activity represented approximately 32% of our 
units on rent at December 31, 2004, and because of the degree of operating leverage we have, declines in non-residential construction 
activity can have a significant effect on our operating margins and net income.  In 2002 and 2003, we saw weakness in the level of 
leasing revenues from the non-residential construction sector of our customer base.  The lower than historical growth rate in revenues 
combined with increases in fixed costs depressed our growth in adjusted EBITDA (as defined below) in those years.  In 2004, the level 
of non-residential construction activity in the U.S. leveled off and rose slightly after two years of steep declines.  As a result of the 
improvement in the non-residential construction sector and the general improvements in the economy, our adjusted EBITDA began to
grow rapidly in 2004. 

In managing our business, we focus on our internal growth rate in leasing revenue, which we define as growth in lease revenues on a 
year  over  year  basis  at  our  branch  locations  in  operation  for at  least one year, without inclusion of same market acquisitions.  This 
24

internal growth rate has remained positive every quarter, but in 2002 and 2003 had fallen to single digits, from over 20% prior to 2002, 
due to the slowdown in the economy, especially as the slowdown affected the non-residential construction sector in certain areas where 
we have large branch operations, including Texas and Colorado.  We achieved an internal growth rate in 2004 of 16.0%, reflecting an 
improvement in both economic and market conditions.  Mobile Mini’s goal is to maintain a high internal growth rate so that revenue 
growth will exceed inflationary growth in expenses and we can continue to take advantage of the operating leverage inherent in our 
business model. 

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  is  a  measure  of  our  earnings  before  interest  expense,  debt
restructuring  costs,  provision  for  income  taxes,  depreciation  and  amortization.    This  measure  eliminates  the  effect  of  financing
transactions that we enter into on an irregular basis based on capital needs and market opportunities, and this measure 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  ignore  the  effect  of  what  we  consider  non-recurring  events  not 
related to our core business operations to arrive at adjusted EBITDA.  The only non-recurring event reflected in the adjusted EBITDA 
has been the effect in 2002 and in 2003 of our Florida litigation expense.  The litigation was concluded in 2003.  In addition, several of 
the  covenants  contained  under  our  revolving  credit  facility  are  expressed  by  reference  to  this  adjusted  EBITDA  financial  measure,
similarly  computed.    Because  EBITDA  is  a  non-GAAP  financial  measure,  as  defined  by  the  SEC,  we  include  in  this  Report  a 
reconciliation of EBITDA to the most directly comparable financial measures calculated and presented in accordance with accounting 
principles generally accepted in the United States.  This reconciliation is included in Item 6, “Selected Financial Data.” 

In managing our business, we routinely compare our adjusted EBITDA margins from year to year and based upon age of branch. We 
define  this  margin  as  adjusted  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 adjusted 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 market or branch, we must first fund 
and  absorb  the  startup  costs  for  setting  up  the  new  branch  facility,  hiring  and  developing  the  management  and  sales  team  and 
developing our marketing and advertising programs.  A new branch will have low adjusted EBITDA margins in its early years until the 
number of units on rent increases.  Because of our high 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 significant growth in leasing revenues, the adjusted 
EBITDA margin at a branch will remain relatively flat on a period by period comparative basis. 

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 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,  refurbish  and  modify  used  ocean-going
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, commissions 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 2.4% 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). 

Our principal asset is our lease fleet, which has historically maintained value close to its original cost.  Prior to 2004, our lease fleet 
units  (other  than  van trailers) were historically depreciated on the straight-line method over our units’ estimated useful life, in most 
cases 20 years after the date that we put the unit in service, with estimated residual values of 70% on steel units.  Effective in 2004, we 
began to depreciate the steel units in our lease fleet using an estimated useful life of 25 years, after the date the unit is placed in service, 
with  an  estimated  residual  value  of  62.5%,  which  effectively  results  in  depreciation  on  these  units  at  the  same  annual  rate.    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 twenty 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. See “Item 1. Business — Product Lives and Durability.”

Our branch expansion program and other factors can affect our overall utilization rate.  From 1996 through 2004, our annual utilization 
levels averaged 81.7%, and ranged from a low of 78.7% in 2003 to a high of 89.7% in 1996.  The lower utilization rate in the last few 
years was primarily a result of (i) the fact that many of our acquired branches, at the time of the acquisition transaction and for various 
periods  thereafter,  have  had  utilization  levels  lower  than  our  historic  average  rates,  especially  after  we  have  added  our  proprietary 
product,  (ii)  the  fact  that  it  is  easier  to  maintain  a  higher  utilization  rate  at  a  large  branch  but  we  increased  the  number  of  small 
branches  in  more  recent  years,  and  (iii)  the  economic  slowdown  in  the  general  economy  and  in  particular  the  slowdown  in  the 
construction  sector.    We  entered  six  markets  in  2001,  11  markets  in  2002, and one market in 2003 and 2004, typically resulting  in 
reduced overall utilization rates as our system absorbs the added assets.  With the addition of fewer markets in 2003 and in 2004, we 
are  focusing  on  increasing  our  utilization rate by balancing inventory between markets and decreasing the number of out of service
units.  Our utilization rate increased from 78.7% in 2003 to 80.7% in 2004.  From the end of 1996 through the end of 2004, we grew 
our lease fleet from 13,600 units to 100,600 units, representing a CAGR of 28.4%.  Our utilization is somewhat seasonal with the low 
realized in the first quarter and the high realized in the fourth quarter.

Twelve Months Ended December 31, 2004 Compared to Twelve Months Ended December 31, 2003 

Total revenues in 2004 increased $21.8 million, or 14.9%, to $168.3 million from $146.6 million in 2003.  Leasing of portable storage 
units  and  portable  offices  accounted  for  approximately  89.0%  of  total  revenues  during  2004.    Leasing  revenues  in  2004  increased
$21.4 million, or 16.6%, to $149.9 million from $128.5 million in 2003.  This increase resulted primarily from a 4.1% increase in the 
average rental yield per unit and a 12.1% increase in the average number of units on lease.  In 2004, our internal growth rate increased 
to approximately 16.0% as compared to approximately 7.4% in 2003.  We define internal growth as the growth in lease revenues in
markets opened for at least one year, excluding any growth arising as a result of additional acquisitions in those markets.  The level of 
our internal growth rate in 2003 was principally due to general U.S. domestic economic weakness, particularly associated with the non-
residential  construction  sector  and  particularly  in  several  of  our  more  established  markets.    Internal  growth  at  many  of  our  newer 
locations was strong during 2003.  During 2004, we saw a steady improvement in our internal growth rate from the previous year’s
level.  The internal growth rate during the four quarters of 2004 was 7.8%, 14.9%, 17.7% and 22.2%, respectively.  We completed
only one small acquisition in Detroit, Michigan in 2004.  Sales of portable storage units have accounted for 10.7%  and 11.8% in 2004 
and  2003,  respectively,  of  our  total  revenues,  and  we  generated  less  than  1.0%  of  our  total  revenues  from  other  miscellaneous 
revenues, primarily related to our sales business and principally arising from transportation charges for the delivery of units sold and 
the sale of ancillary products.  Our revenues from the sale of portable storage units increased $0.7 million, or 3.9%, to $17.9 million in

2004  from  $17.2  million  in  2003.    This  increase  in  sales  revenue  was  due  to  an  increase  in  both  the  price  of  steel  and  used  steel
containers, which we were able to pass on to customers who purchased our units, resulting in a higher price per unit sold.  This price 
increase was almost completely offset by a lower volume of units sold, as the higher sales prices made it more attractive for customers 
to lease rather than buy containers. 

Cost of sales is the cost to us of units we sold during the period.  Cost of sales as a percentage of sales revenues decreased to 63.4% in 
2004 from 66.6% in 2003.  The higher profit margins in 2004 primarily related to our economies of scale associated with our higher 
number of units produced in 2004 resulting in lower manufacturing costs, partially offset by the increase in steel prices. 

Leasing,  selling  and  general  expenses  increased  $10.6  million,  or  13.5%,  to  $89.7  million  in  2004  from  $79.1  million  in  2003.  
Leasing, selling and general expenses, as a percentage of total revenues, were 53.3% and 53.9% in 2004 and 2003, respectively. These 
expenses as a percentage of total revenue declined due to the operating leverage in the Company’s business model.  As units on rent 
are added to existing branches, the growth in revenues far exceeds the growth in leasing, selling and general expenses related to the 
incremental  lease  revenue.    These  economies  of  scale  were  offset  to  some  extent  by  increases  in  certain  expense  levels.    Freight
trucking  expense  increased  by  $2.1  million  as  we  used  more third-party vendors for the transportation of our units, particularly our 
modular office units (which are more expensive to transport), and due to the repositioning of some of our lease fleet units from city to 
city.  We repositioned units to meet our customers’ demand by more efficiently using our existing resources, which also resulted in 
higher overall utilization rates.  Repairs on our lease fleet increased by $1.7 million due to our increased maintenance efforts which 
were related to the increase in our overall utilization rates.  Fuel expenses increased by $0.8 million due to fuel price increases and the 
increase  in  the  number  of  deliveries  and  pick  ups  due  to  our  larger  fleet  size  and  customer  base.    Repairs  and  maintenance  of 
equipment increased by $0.7 million principally as a result of our preventative maintenance programs and general repairs associated
with  servicing  a  larger  lease  fleet.    Real  estate  rent  expense  increased  by  $0.6  million  for  the  lease  properties  obtained  in  our  two 
acquisitions in 2003 and 2004, new properties and lease renewals at certain of our branch locations and the general inflationary index 
clauses in our lease agreements. 

Florida litigation expense in 2003 relates to litigation and related costs incurred in connection with litigation which was concluded in 
2003.

EBITDA  in  2004  was  $67.3  million.    In  2003,  EBITDA  was  $47.5  million,  which  included  the  effect  of  $8.5  million  of  Florida 
litigation expense.  EBITDA increased in 2004 by 41.6%; adjusted EBITDA increased in 2004 by approximately 20.1%. 

Depreciation and amortization expenses increased $1.3 million, or 12.0%, to $12.4 million in 2004 from $11.1 million in 2003.  The 
higher  depreciation  was  directly  related  to  a  larger  fleet  in  2004,  which  enabled  us  to  achieve  higher  lease  revenues,  includes  the 
depreciation expenses associated with the refurbishment of portable storage units added to the lease fleet during 2004 and the inclusion 
in  the  lease  fleet  of  additional  wood  modular  offices  which  have  a  higher  depreciation  rate  than  our  steel  units.    By  increasing  our 
overall utilization rate, we were able to grow revenues faster than we increased the size of our lease fleet.  Since December 31, 2003, 
our  lease  fleet  cost  basis  for  depreciation  increased  by  $76.5  million.    See “Critical Accounting Policies and Estimates” within this 
Item 7. 

Interest expense increased $4.1 million, or 25.4%, to $20.4 million in 2004 from $16.3 million in 2003.  Our average debt outstanding 
during 2004, compared to 2003, increased by 14.9%, primarily due to increased borrowings under our credit facility to fund the growth 
of our lease fleet during the year.  The increase in interest expense includes the higher interest cost associated with our Senior Notes, 
which  effectively  increased  the  weighted  average  interest  rate  on  our  debt  to  7.5%  for  2004  from  6.8%  for  2003,  excluding 
amortization of debt issuance costs.  Taking into account the amortization of debt issuance costs, the weighted average interest rate was 
7.8% in 2004 and 7.1% in 2003.  Our weighted average interest rate is higher in 2004 due to the full year effect of the higher interest 
rate  on  the  Senior  Notes,  which  were  issued  at the end of June 2003.  Our Senior Notes bear interest at 9.5% per annum, which is 
higher than the average borrowing rate under our revolving credit facility.  On an annualized basis, the additional interest cost incurred 
under the Senior Notes versus the senior secured credit facility, which was our sole source of borrowing prior to our issuance of the 
Senior Notes, was approximately $6 million based on floating rates and swap rates in effect at the time the transaction was concluded.  
However,  the  issuance  of  the  Senior  Notes  in  2003  provided  the  Company  a  great  deal  of  additional  liquidity.    See  “Liquidity  and
Capital Resources” within this Item 7. 

Debt restructuring expense in 2003 was $10.4 million and includes the termination expenses (approximately $8.7 million) related to 
unwinding certain interest rate swap agreements relating to debt repaid with the proceeds from our sale during June 2003 of $150.0
million of Senior Notes and the write off of certain capitalized debt issuance costs (approximately $1.7 million) associated with our 
revolving credit agreement before it was amended and restated in June 2003.

Provision  for  income  taxes  was  based  on  an  annual  effective  tax  rate  of  40.0% for 2004 and 39.0% for 2003.  The increase in our 
effective tax was primarily due to certain state tax loss carryforwards that we believe will expire before we will be able to utilize them.  
At December 31, 2004, we had a federal net operating loss carryforward of approximately $61.3 million, which expires if unused from 
2009 to 2024.  In addition, we had net operating loss carryforward 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 2004 was $20.7 million, as compared to $5.9 million in 2003.  In 2003, net income included after-tax charges of $5.2
million related to Florida litigation expense and after-tax charges of $6.4 million related to debt restructuring expense.   

Twelve Months Ended December 31, 2003 Compared to Twelve Months Ended December 31, 2002 

Total revenues in 2003 increased $13.5 million, or 10.1%, to $146.6 million from $133.1 million in 2002.  Leasing portable storage 
units and portable offices accounts for the majority of our revenues, and accounted for approximately 87.7% of total revenues during 
2003.    Leasing  revenues  in  2003  increased  $12.3  million,  or  10.6%, to $128.5 million from $116.2 million in 2002.  This increase
resulted  primarily  from  an  11.9%  increase  in  the  average  number  of  units  on  lease.    In  2003,  our  internal  growth  rate  was 
approximately 7.4% as compared to approximately 7.5% in 2002.  We completed only one small acquisition in Portland, Oregon in 
late 2003.  The slowdown in our internal growth rate in 2002 and 2003 is principally due to general economic weakness, particularly 
associated with the non-residential construction sector and particularly in several of our more established markets.  Internal growth at 
many  of  our  newer  locations  was  strong.    This  growth  was  offset  by  weakness  at  certain  of  our  older  more  established  branches, 
especially  those  in  Texas  and  Colorado,  which  were  affected  by  weakness  in  construction  in  the markets that those branches serve.
Sales  of  portable  storage  units  have  accounted  for  approximately  11.8%  to  12.0%  in  2003  and  2002,  respectively,  of  our  total 
revenues,  and  we  generate  less  than  1.0%  of  our  total  revenues  from  other  miscellaneous  revenues,  primarily  related  to  our  sales
business, principally transportation charges for the delivery of units sold and the sale of ancillary products.  Our revenues from the sale 
of portable storage units increased $1.2 million, or 7.8%, to $17.2 million in 2003 from $16.0 million in 2002.  This 7.8% increase is 
partially due to increase sales at the locations we added in 2002 and a large government sale in the fourth quarter 2003, partially offset 
by lower sales volume at our more established locations. 

Cost of sales is the cost to us of units that we sold during the period.  Cost of sales increased $1.1 million, or 11.1%, to $11.5 million 
in 2003 from $10.3 million in 2002.  Cost of sales, as a percentage of sales revenues, increased to 66.6% in 2003 from 64.6% in 2002.  
This slight decrease in sales margins is not significant and is partially attributable to lower margins on the government sale made in the 
fourth quarter 2003, and the sales of van trailers at much lower margins than our principal products.   

Leasing, selling and general expenses increased $9.9 million, or 14.3%, to $79.1 million in 2003 from $69.2 million in 2002.   Leasing, 
selling and general expenses, as a percentage of total revenues, was 53.9% and 52.0% in 2003 and 2002, respectively.  These expenses 
as  a  percentage  of  total  revenues  declined  at  older  branches, as we were able to benefit from economies of scale as those branches 
grew.  This was offset by higher leasing, selling and general expenses as a percentage of total revenues at newer branches.  In general, 
new  branches  initially  have  lower  operating  margins  until  their  fixed  operating  costs  are  covered  by  higher  leasing  volumes  that
typically are not achieved until the branch has been operated for several years.  Among the other major increases in leasing, selling and 
general expenses in 2003 were increases in insurance expense ($2.1 million), advertising expense ($0.7 million), rent expense ($0.5
million) which related in significant part to the addition of 11 new locations during the second half of 2002, property tax expense ($0.8 
million) and fuel expenses incurred in connection with the delivery and pick up of leased containers ($0.7 million). 

Florida litigation expense relates to litigation and related costs incurred in connection with our Florida litigation which was concluded 
in 2003.  We recorded approximately $8.5 million and $1.3 million of costs and legal expenses in connection with this suit and related 
litigation in 2003 and 2002, respectively.   

EBITDA in 2003 was $47.5 million, which included the effect of $8.5 million of Florida litigation expense.  In 2002, EBITDA was
$52.2 million, which included the effect of $1.3 million of Florida litigation expense. 

Depreciation and amortization expenses increased $1.6 million, or 17.1%, to $11.1 million in 2003 from $9.5 million in 2002.  The 
higher  depreciation  was  directly related to a larger fleet in 2003,  which enabled Mobile Mini to achieve higher lease revenues, and 
includes  depreciation  expenses  associated  with  the  refurbishment  of  portable  storage  units  added  to  the  lease  fleet  during  2003
following our acquisition of the units in transactions that occurred during 2002 and prior years and includes the higher depreciation 
rate  associated  with  wood  mobile  offices  which  were  a  larger  part  of  our  fleet  in  2003.    See  “Critical  Accounting  Policies  and 
Estimates” within this Item 7. 

28

Interest expense increased $4.7 million, or 40.7%, to $16.3 million in 2003 from $11.6 million in 2002.  The increase was primarily 
the result of the issuance in June 2003 of our Senior Notes, the proceeds of which were used to replace lower interest secured debt.  
Our average debt outstanding during 2003, compared to 2002, increased by 17.0%, with most of the increase occurring during the first 
six months of 2003, primarily due to increased borrowings under our credit facility to fund the growth of our lease fleet during that 
period.  The increase in interest expense includes the higher interest cost associated with our Senior Notes, which effectively increased 
the weighted average interest rate on our debt to 6.8% for 2003 from 5.7% for 2002, excluding amortization of debt issuance costs.
Taking into account the amortization of debt issuance costs, the weighted average interest rate was 7.1% in 2003 and 5.9% in 2002.
Our Senior Notes bear interest at 9.5% per annum, which is higher than the average borrowing rate under our revolving credit facility.  
On  an  annualized  basis,  the  additional  interest  cost  incurred  under  the  Senior  Notes  versus  the  senior  secured  credit  facility  is
approximately  $6  million  based  on  floating  rates  and  swap  rates  in  effect  at  the  time  the  transaction  was  concluded.   However,  the 
issuance of the Senior Notes provided the Company with a great deal of additional liquidity.  See “Liquidity and Capital Resources” 
within this Item 7. 

Debt restructuring expense in 2003 was $10.4 million and includes the termination expenses (approximately $8.7 million) related to 
unwinding certain interest rate swap agreements relating to debt repaid with the proceeds from our sale during June 2003 of $150.0
million of Senior Notes and the write off of certain capitalized debt issuance costs (approximately $1.7 million) associated with our 
revolving  credit  agreement  before  it  was  amended  and  restated  in  June  2003.    During  2002,  we  incurred  $1.3  million  of  expense 
related to the write off of certain capitalized debt issuance costs associated with a former credit agreement.  The 2002 transaction was 
recorded  as  an  extraordinary  item  in  2002  pursuant  to  SFAS  No.  4,  Reporting  Gains  and  Losses  from  Extinguishment  of  Debt.    In 
accordance with SFAS No. 145, which among other things rescinded  SFAS No. 4, the 2002 transaction has been reclassified in our 
consolidated statements in pre-tax earnings as debt restructuring expense. 

Provision for income taxes was based on an annual effective tax rate of 39.0% for both 2003 and 2002.  At December 31, 2003, we 
had a federal net operating loss carryforward of approximately $67.9 million, which expires if unused from 2008 to 2023.  In addition, 
we had net operating loss carryforward in the various states in which we operate.   

Net income in 2003 was $5.9 million, which included after tax charges of $5.2 million related to Florida litigation expense and after 
tax charges of $6.4 million related to debt restructuring expense.  In 2002, net income was $18.2 million, which included the after tax 
charge of $0.8 million related to Florida litigation expense and an after tax charge of $0.8 million related to debt restructuring expense.

Liquidity and Capital Resources  

Liquidity Summary

Most  of  Mobile  Mini’s  capital  expenditures  are  comprised  of  discretionary  purchases  of  inventory,  lease  fleet  units  and  equipment 
related  to  the  expansion  of  our  business.    Currently,  we  spend  approximately  $2.5  million  to  $3.0  million  per  year  in  maintenance
capital expenditures to replace forklifts, delivery trucks, trailers and enhancements to computer information systems.  Mobile Mini’s 
outside sources of liquidity include a $250.0 million senior secured revolving line of credit, public equity offerings completed in 1999 
and  2001  and  a  $150.0  million  Senior  Note  offering  completed  in  2003.    Approximately  $125.9  million  and  $89.0  million  was 
outstanding at December 31, 2004 and 2003, respectively,  under our $250.0 million senior secured revolving line of credit.   

Since 1996, Mobile Mini has focused the growth of its business on its leasing operations.  Leasing is a capital intensive business that 
requires that we acquire assets before they generate revenues, cash flow and earnings.  The assets Mobile Mini leases have very long 
useful  lives  and  require  relatively  little  recurrent  maintenance  expenditures.    Most  of  the  capital  Mobile  Mini  has  deployed  into  its 
leasing business has been of a discretionary nature in order to expand the company’s operations geographically, to increase the number 
of units available for lease at the company’s leasing locations, and to add to the mix of products the company offers.   During recent 
years, Mobile Mini’s operations have generated cash flow that exceeds the company’s pre-tax earnings, particularly due to the deferral 
of income taxes due to accelerated depreciation which is used for tax accounting. 

Historically, Mobile Mini has funded much of its growth through equity and debt issuances and borrowings under its revolving credit 
facility.    Recently,  Mobile  Mini  has  been  able  to  fund  more  of  its  capital  expenditures  from  operating  cash  flow,  and  during  2004
Mobile Mini funded a good portion of its $81.3 million of capital expenditures with operating cash flow of $42.3 million. Borrowings 
under its revolving credit facility increased in the aggregate by $36.9 million between December 31, 2003 and December 31, 2004.

Operating Activities.  Our operations provided net cash flow of $42.3 million (after payment of an $8.0 million judgment relating to 
certain litigation in Florida) in 2004 compared to $43.1 million in 2003 and $45.4 million in 2002.  The $0.8 million decrease in 2004 
over  2003  in  cash  provided  by  operating  activities  was  due  primarily  to  payment  of  the  $8.0  million  judgment  and  to  increases  in
accounts  receivables  and  in  inventory  (primarily  raw  materials  and  supplies),  deposits  and  prepaid  expenses,  partially  offset  by  an 
increase in accounts payable.  Cash provided by operating activities is enhanced by the rapid tax depreciation rate of our assets and our 
federal and state net operating loss carryforwards, which minimizes our tax payments at this time.  At December 31, 2004 we had a 
federal net operating loss carryforward of approximately $61.3 million and a deferred tax liability of $59.8 million. 

Investing Activities.  Net cash used in investing activities was $82.4 million in 2004, $57.6 million in 2003 and $93.3 million in 2002.  
In 2004, $1.3 million of cash was paid for acquisition of a business, compared to $1.7 million in 2003 period and $30.8 million in 
2002.  Capital expenditures for our lease fleet were $76.6 million for 2004, $52.0 million for 2003 and $57.0 million in 2002.  Capital 
expenditures  increased  during  2004  due  to an increase in demand which required us to purchase and refurbish more containers and
offices than in 2003 and due to an increase in the cost of used shipping containers and modular offices, as well as the price of raw 
materials,  especially  steel.    During  the  past  several  years,  our  fleet  has  become  more  customized,  enabling  us  to  differentiate  our 
product  from  our  competitors’  product.    Capital  expenditures  for  property,  plant  and  equipment  were  $4.7  million  in  2004,  $4.5 
million in 2003 and $5.9 million in 2002.  The amount of cash that we use during any period in investing activities is almost entirely 
within management’s discretion.  Mobile Mini has 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.  Our maintenance capital expenditures 
during 2004 were approximately $2.5 million, to cover 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 systems. 

Financing Activities.  Net cash provided by financing activities was $40.6 million in 2004, $12.7 million in 2003, and $49.0 million in 
2002.  During 2004, we primarily relied on cash provided by operations as well as our credit facility to provide the additional cash 
needed to fund the growth of our lease fleet.  Additionally, we received $4.4 million from the exercises of employee stock options.  In 
2003,  Mobile  Mini  completed  an  offering  of  $150.0  million  of  9.5%  Senior  Notes  due  2013  and,  at  the  same  time,  amended  its 
revolving credit facility to revise certain covenants.  The net proceeds of the Senior Notes offering were used in part to unwind certain 
interest rate swap agreements (approximately $8.7 million) that had been entered into to hedge floating rate indebtedness outstanding 
under  the  revolving  credit  facility  prior  to  the  transaction,  and  the  remainder  of  the  net  proceeds  was  used  to  repay  borrowings
outstanding under the revolving credit facility.  Upon the closing of the transactions, most of Mobile Mini’s outstanding debt was fixed 
rate debt, and the amount of unused borrowings available to Mobile Mini under the revolving credit facility increased to approximately 
$76.4 million.  We used $36.3 million less cash in financing activities during 2003 as compared to 2002, primarily as a result of our 
strategic  decision  to  forego  most  business  acquisition  opportunities  during  2003  in  order  to  focus  on  growing  our  existing  branch 
network.    As  of  December 31,  2004,  we  had  $125.9  million  of  borrowings  outstanding  under our credit facility, and approximately
30

$110.7  million  of  additional  borrowings  were  available  to  us  under  the  facility.    As  of  March  1,  2005,  our  borrowings  outstanding
under our credit facility were approximately $134.3 million. This increase is primarily due to the semi-annual interest payment on the 
Senior Notes in January 2005 ($7.1 million).   

The  interest  rate  under  our  revolving  credit  facility  is  based  on  our  ratio  of  funded  debt  to  earnings  before  interest  expense,  taxes, 
depreciation and amortization, debt restructuring expenses and any judgment or settlement costs related to our Florida litigation.  In 
August 2004, we amended our senior secured revolving line of credit to reduce the interest rate by reducing the spread over LIBOR 
which  we  pay  at  various  levels  of  leverage.    The  interest  rate,  as  calculated  at  December  31,  2004,  under  our  credit  facility  is  the 
LIBOR  (London  Interbank  Offered  Rate)  rate  plus  2.0%  or  the  prime  rate  plus  0.25%,  whichever  we  elect,  subject  to  certain 
conditions.   

All  of  our  obligations  under  the  revolving  credit  facility  are  unconditionally  guaranteed  jointly  and  severally  by  each  of  our 
subsidiaries.  The revolving credit facility and the related guarantees are secured by substantially all of our assets and all assets of each 
guarantor,  including  but  not  limited  to  (i)  a  first-priority  pledge  of  all  of  the  outstanding  capital  stock  or  other  ownership  interest 
owned by us and each guarantor and (ii) first-priority security interests in all of our tangible and intangible assets and the tangible and 
intangible assets of each guarantor (in each case, other than certain equipment assets subject to capitalized lease obligations).  As of 
December 31, 2004, we had no capital lease obligations. 

Loans under the revolving credit facility bear interest at a rate based, at our option and subject to certain conditions, on either (1) the 
prime rate plus a spread ranging from 0.00% (nil) to 0.75% depending on our leverage ratio, or (2) the London inter-bank offered rate, 
which we refer to as LIBOR, plus a spread ranging from 1.75% to  2.50% depending on our leverage ratio.  Interest on outstanding
borrowings  is  payable  monthly  or,  with  respect  to  LIBOR  borrowings,  either  quarterly  or  on  the  last  day  of  the  applicable  interest 
period (whichever is more frequent).  In addition to paying interest on any outstanding principal amount, we pay an unused revolving 
credit facility fee to the senior lenders equal to a range of 0.30% to 0.50% per annum on the unused daily balance of the revolving 
credit commitment, payable monthly in arrears, based upon the actual number of days elapsed in a 360 day year.  For each letter of 
credit we issue, we pay (i) a per annum fee equal to the margin over the LIBOR rate from time to time in effect, (ii) a fronting fee on 
the aggregate outstanding stated amounts of such letters of credit, plus (iii) customary administrative charges. 

The  credit  facility  documentation  contains  covenants  restricting  our  ability  to,  among  others  (i)  declare  dividends  or  redeem  or
repurchase  capital  stock,  (ii)  prepay,  redeem  or  purchase  other  debt,  (iii)  incur  liens,  (iv)  make  loans  and  investments,  (v)  incur 
additional  indebtedness,  (vi)  amend  or  otherwise  alter  debt  and  other  material  agreements,  (vii)  make  capital  expenditures,  (viii)
engage  in  mergers,  acquisitions  and  asset  sales,  (ix)  transact  with  affiliates,  and  (x)  alter  the  business  we  conduct.    We  also  must 
comply  with  specified  financial  covenants  and  affirmative  covenants.    These  financial  covenants  set  maximum  values  for  Mobile 
Mini’s leverage, fixed charge coverage, capital expenditures, and minimum values for lease fleet utilization rates.  The leverage or debt 
ratio covenant requires that our ratio of funded debt to EBITDA (as defined in our revolving credit agreement) not exceed a specified 
ratio, which is 5.75 to 1.0 currently and which decreases to 5.5 to 1.0 at December 31, 2005 and thereafter. EBITDA for purposes of 
this  covenant  (i)  includes  our  net  income  plus  the  amount  of  any  non-cash  extraordinary  losses  and  debt  restructuring  costs  arising 
from  payments  of  termination  costs  of  interest  rate  swaps  and  from  write-offs  of  fees  and  expenses  in  connection  with  the  initial
funding under the loan and security agreement and (ii) gives pro forma effect to any permitted acquisition, in each case measured over 
our fiscal quarters ending on each quarterly measurement date.  Our debt ratio covenant excludes all accruals and payments made by us 
in connection with our Florida litigation, which was concluded in 2003.  Our fixed charge coverage ratio is required to be at least 1.85 
to 1.0 and is defined as the ratio of our cash flow for four quarters to the sum of interest expense for such four quarters plus the current 
portion of our funded debt, but the calculation excludes accruals or cash payments made in connection with our Florida litigation.  Our 
capital expenditure covenant limits our permitted payments made in connection with the acquisition of fixed assets to $115 million per 
year,  as  adjusted  by  annual  carry-forward  amounts  plus  an  amount  equal  to  300%  of  the  net  cash  proceeds  we  receive  from  any 
issuance  of  our  equity  securities.    Portable  containers  held  for  sale  and  inventory  and  equipment  acquired  in  connection  with 
acquisition permitted under our revolving credit agreement are excluded from the capital expenditures covenant limitation.  Our lease 
fleet utilization covenant requires us to maintain minimum utilization ranging from 75% to 77.5%, depending upon the fiscal quarter
that  is  the  measurement  period.    The  credit  facility  also  contains  limitations  on,  among  other  things,  incurring  debt,  granting  liens, 
making  investments,  making  restricted  payments,  entering  into  transactions  with  affiliates  and  prepaying  subordinated  debt.    Our
compliance  with  financial  covenants  is  measured  as  of  the  last  day  of  each  fiscal  quarter.    We  were  in  compliance  with  all  the 
covenants under the revolving credit facility agreement at December 31, 2004. 

Events of default under the revolving credit facility include, but are not limited to, (i) our failure to pay principal or interest when due, 
(ii) our material breach of any representations or warranty, (iii) covenant defaults, (iv) events of bankruptcy, (v) cross default to certain 
other debt, (vi) certain unsatisfied final judgments over a stated threshold amount, and (vii) a change of control.

Prior to June 2003, we entered into interest rate swap agreements under which we effectively fixed the interest rate payable on $135.0 
million of borrowings under our credit facility so that the rate is based upon a spread from fixed rates, rather than a spread from the 
LIBOR rate.  In June 2003, in conjunction with our sale of our Senior Notes and the amendment of our credit facility, we terminated
$110.0 million  of  these  swap  agreements.    Accounting  for  these  swap  agreements  is  covered  by  Statement  of  Financial  Accounting 
Standard (SFAS) No. 133, and pursuant to SFAS No. 133, the swap termination resulted in a charge to net income of approximately
$5.3 million, net of an income tax benefit of approximately $3.4 million at June 30, 2003.  At December 31, 2004 and 2003, we had
one interest rate swap agreement for $25.0 million of debt.  In January 2005, we entered into another interest rate swap agreement for 
an additional $25.0 million of debt.  At December 31, 2004, a majority of our outstanding indebtedness bears interest at fixed rates (or 
the  rate  is  effectively fixed due to a swap agreement), and approximately $100.9 million of borrowings under our credit facility are 
variable rate.  

Mobile Mini believes that it has sufficient borrowings available under the facility to provide for its foreseeable capital needs over the 
next 12 to 36 months, with the duration dependent in large part upon the balance between the internal growth rates achieved during 
2005 and subsequent periods and the expenses of entry into additional markets during the period, which will be the main determinant 
of how quickly the company uses its additional borrowing capacity under the revolving credit facility. 

Contractual Obligations and Commitments        

Our contractual obligations primarily consist of our outstanding balance under our secured revolving credit facility and $150.0 million 
of unsecured Senior Notes, together with other notes payable obligations both secured and unsecured.  We also have operating lease 
commitments for:  1) real estate properties for the majority of our branches with remaining lease terms on our major leased properties 
ranging from 2 to 11 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) other equipment, primarily  office  machines. 

In connection with the issuance of our insurance policies, we have provided our various insurance carriers approximately $3.3 million 
in letters of credit and an agreement under which we are contingently responsible for $1.2 million to provide credit support for our 
payment of the deductibles and/or loss limitation reimbursements under the insurance policies. 

We  currently  do  not  have any obligations under purchase agreements or commitments.  Historically, we enter into capitalized lease 
obligations from time to time to purchase delivery, transportation and yard equipment, but currently have no commitments recorded as 
a capital lease. 

The table below provides a summary of our contractual commitments as of December 31, 2004.  The operating lease amounts include
the extended terms on real estate lease option renewals on those properties we currently anticipate we will exercise at the end of the 
lease term.

Off-Balance Sheet Transactions 

Mobile Mini does 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 Mobile Mini’s 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 inventory for the holiday season.  Our retail
customers usually return these leased units to us early in the following year.  This causes lower utilization rates for our lease fleet and a 
marginal decrease in cash flow during the first quarter of the 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. 

Mobile Mini’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the 
United States.  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 Securities and Exchange Commission 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  units  and  office 
units  are  recognized  monthly, which approximates a straight-line basis.  Revenues and expenses from portable storage unit delivery 
and  hauling  are  recognized  when  these  services  are  billed,  in  accordance  with  SAB  101,  as  amended  by  SAB  104.  We  recognize 
revenues from sales of containers and office units upon delivery.   

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 at December 31, as follows:

Diluted earnings per share

If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional 
allowances may be required. 

33

 
 
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: 

•  Significant under-performance relative to historical, expected or projected future operating results; 
•  Significant changes in the manner of our use of the acquired assets or the strategy for our overall business;  
•  Our market capitalization relative to net book value, and 
•  Significant negative industry or general economic trends. 

When we determine the carrying value of goodwill and other identified intangibles may not be recoverable, we measure impairment
based on a projected discounted cash flow method using a discount rate determined by our management to be commensurate with the
risk inherent in our current business model.  In accordance with SFAS No. 142, Goodwill and Other Intangible Assets, on January 1, 
2002, we ceased amortizing goodwill arising from acquisitions completed prior to July 1, 2001.  We tested goodwill for impairment 
using  the  two-step  process  prescribed  in  SFAS  No.  142.    The  first  step  is  a  screen  for  potential  impairment,  while  the  second  step 
measures  the  amount  of  the  impairment,  if  any.    We  performed  the  annual  required  impairment  tests  for  goodwill  at  December  31, 
2002, December 31, 2003 and December 31, 2004, and determined that the carrying amount of goodwill was not impaired as of those
dates.  We will perform this test in the future as required by SFAS No. 142.  

Impairment 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. 

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 25 years with an estimated residual value of 62.5%.  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.  Van trailers are only added to the fleet as a result of acquisitions of portable 
storage businesses.  

In 2004, our depreciation policy on our steel units was modified to increase the useful life to 25 years (from 20 years), and to decrease 
the residual value to 62.5% (from 70%), which effectively resulted in continued depreciation on steel units for five additional years at 
the same annual rate (1.5%).  This change was made to reflect that some of our steel units have now been in our lease fleet longer than 
20 years and these units continue to be effective income producing assets that do not show signs of reaching the end of their useful life.  
The depreciation policy is supported by our historical lease fleet data that shows we have been able to retain comparable rental rates 
and sales prices irrespective of the age of the unit in our container lease fleet.   

34

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 62.5% residual value and a 
25-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  and  useful  life  would  have  the  following  approximate  effect  on  our  net  income  and  diluted  earnings  per  share  as
reflected in the table below.

Insurance Reserves.  Our worker’s compensation, auto and general liability insurance is purchased under large deductible programs.  
Our current per incident deductibles are: worker’s compensation $250,000, auto $100,000 and general liability $100,000.  We expense 
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.    Management’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 (as that term is defined in SFAS No. 5) 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 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.

Recent Accounting Pronouncements 

SFAS  No.  123,  (Revised  2004)  (SFAS  No.  123(R)),  Share-Based  Payment,  was  issued  in  December  2004.   SFAS  No.  123(R)  is  a 
revision  of  FASB Statement 123, Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25,  Accounting for 
Stock Issued to Employees, and its related implementation guidance, which allowed companies to use the intrinsic method of valuing 
share-based  payment  transactions.  SFAS  No.  123(R)  focuses  primarily  on  accounting  for  transactions  in  which  an  entity  obtains 
employee  services  in  share-based  payment  transactions.  SFAS  No.  123(R)  requires  a  public  entity  with  share-based  payments  to 
employees, including grants of employee stock options, to be recognized in the financial statements based on the fair-value method as 
defined in Statement 123. Pro forma disclosure is no longer an alternative.  That cost will be recognized over the period during which 
an employee is required to provide service in exchange for the award. This statement is effective as of the beginning of the first interim 
or annual reporting period that begins after June 15, 2005.

As permitted by Statement 123, we currently account for share-based payments to employees using the intrinsic value method and, as 
such,  generally  recognize  no  compensation  cost  for  employee  stock  options.    Accordingly,  the  adoption  of  Statement  123(R)’s  fair
value  method  is  expected  to  have  an  impact  on  our  results  of  operations,  although  it  will  have  no  impact  on  our  overall  financial
condition.  The impact upon adoption of Statement 123(R) cannot be predicted at this time because it will depend on levels of share-
based payments granted in the future, the valuation model used to value the options and other variables. 

SFAS No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4, was issued in November 2004.  SFAS No. 151 clarifies 
that abnormal amounts of idle facility expense, freight, handling costs and spoilage should be expensed as incurred and not included in 
overhead.  Further, SFAS No. 151 requires that allocation of fixed and production facilities overheads to conversion costs should be 
based on normal capacity of the production facilities.  The provisions of SFAS No. 151 are effective for fiscal years beginning after 
June 15, 2005.  We do not expect the adoption of SFAS No. 151 to have a material effect on our results of operations or financial
condition. 

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

We enter into derivative financial arrangements only to the extent that the arrangement meets the objectives described above, and we 
do not engage in such transactions for speculative purposes.  

Impact of Foreign Currency Rate Changes.  We currently have branch operations in Toronto, Canada, and we invoice those customers 
primarily in the local currency, the Canadian Dollar, under the terms of our lease agreements with those customers.  We are exposed to 
foreign exchange rate fluctuations as the financial results of our Canadian branch operation are translated into U.S. dollars.  The impact 
of foreign currency rate changes have historically been insignificant. 

Caution Respecting Forward-Looking Statements 

Our disclosure and analysis in this report contains forward-looking information about our Company’s financial results and estimates 
and  our  business  prospects  that  involve substantial risks and uncertainties.  From time to time, we also may provide oral or written 
forward-looking  statements  in  other  materials  we  release  to  the  public.    Forward-looking  statements  are  expressions  of  our  current 
expectations or forecasts of future events.  You can identify these statements by the fact that they do not relate strictly to historic or 
current facts.  They include words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “will,” and other 
words and terms of similar meaning in connection with any discussion of future operating or financial performance.  In particular, these 
include  statements  relating  to  future  actions,  future  performance  or  results,  expenses,  the  outcome  of  contingencies,  such  as  legal 
proceedings, and financial results.  Among the factors that could cause actual results to differ materially are the following: 

• 
• 
• 

• 
• 
• 
• 

• 
• 
• 
• 
• 

• 

our ability to manage our planned growth, both internally and at new branches 
competitive developments affecting our industry, including pricing pressures in newer markets 
economic  slowdown  that  affects  any  significant  portion  of  our  customer  base,  including  economic  slowdown  in  areas  of 
limited geographic scope if markets in which we have significant operations are impacted by such slowdown 
the timing and number of new branches that we open or acquire 
changes in the supply and price of used ocean-going containers 
changes in the supply and cost of the raw materials we use in manufacturing storage units 
legal  defense  costs,  insurance  expenses,  settlement  costs  and  the  risk  of  an  adverse  decision  or  settlement  related  legal 
proceedings 
our ability to protect our patents and other intellectual property 
interest rate fluctuations 
governmental laws and regulations affecting domestic and foreign operations, including tax obligations 
changes in generally accepted accounting principles 
any changes in business, political and economic conditions due to the threat of future terrorist activity in the U.S. and other
parts of the world, and related U.S. military action overseas 
increases in costs and expenses, including costs of raw materials 

We  cannot  guarantee  any  forward-looking  statement  will  be  realized,  although  we  believe  we  have  been  prudent  in  our  plans  and 
assumptions.  Achievement of future results is subject to risks, uncertainties and inaccurate assumptions.  Should known or unknown 
risks  or  uncertainties  materialize,  or  should  underlying  assumptions  prove  inaccurate,  actual  results  could  vary  materially  from  past 
results and those anticipated, estimated or projected.  Investors should bear this in mind as they consider forward-looking statements. 

We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or 
otherwise.  You are advised, however, to consult any further disclosures we make on related subjects in our Form 10-Q, 8-K and 10-K 
reports  to  the  Securities  and  Exchange  Commission.    Our  Form  10-K  lists  and  discusses  (in  “Item  1.  Business”)  various  important
factors that could cause actual results to differ materially from expected and historic results.  We note these factors for investors as 
permitted by the Private Securities Litigation Reform Act of 1995.  Readers can find them in Item 1 of this report under the heading 
“Cautionary Factors That May Affect Future Operating Results.”  You should understand that it is not possible to predict or identify all 
such factors.  Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.  You may 
obtain a copy of our Form 10-K by requesting it from the Company’s Investor Relations Department at (480) 894-6311 or by mail to

Management’s Report on Internal Control Over Financial Reporting 

To the Shareholders of Mobile Mini, Inc., 

The  management  of  Mobile  Mini,  Inc.,  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial 
reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f).  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.  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  our  assets;  (2)  provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit 
preparation  of  financial  statements  in  conformity    with  U.S.  generally  accepted  accounting  principles,  and  that  our  receipts  and
expenditures  are  being  made  only  in  accordance  with  authorizations  of  our  management  and  directors;  and  (3)  provide  reasonable 
assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition  of  our  assets  that  could  have  a 
material effect on the financial statements.   

Because of its inherent limitations, our controls and procedures may not prevent or detect misstatements.  A control system, no matter 
how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the controls system are 
met.    Because  of  the  inherent  limitations  in  all  controls  systems,  no  evaluation  of  controls  can  provide  absolute  assurance  that  all 
control issues and instances of fraud, if any, have been detected.   

Under the supervision and with the participation of management, we assessed the effectiveness of our internal control over financial 
reporting based on the criteria in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission.  Based on our evaluation under the criteria in Internal Control – Integrated Framework, we concluded that 
our internal control over financial reporting was effective as of December 31, 2004.   

Management’s  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2004  has  been 
audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Shareholders of  
Mobile Mini, Inc. 

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial 
Reporting,  that  Mobile  Mini,  Inc.  maintained  effective  internal  control  over  financial  reporting  as  of  December 31,  2004,  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.  Our  responsibility  is  to 
express an opinion on management’s assessment and an opinion on the effectiveness of 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,  evaluating  management’s  assessment,  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal 
control, 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,  management’s  assessment  that  Mobile  Mini,  Inc. maintained effective internal control over financial reporting as of 
December  31,  2004,  is  fairly  stated,  in  all  material  respects,  based  on  the  COSO  criteria.  Also,  in  our  opinion,  Mobile  Mini,  Inc. 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, 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  as  of  December  31,  2004  and  2003,  and  the  related  consolidated  statements  of  income,  stockholders’ 
equity, and cash flows for each of the three years in the period ended December 31, 2004 of Mobile Mini, Inc. and Subsidiaries, and 
our report dated March 10, 2005 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Shareholders  
Mobile Mini, Inc. 

We have audited the accompanying consolidated balance sheets of Mobile Mini, Inc. and subsidiaries as of December 31, 2004 and 
2003, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period 
ended  December  31,  2004.  Our  audit  also  included  the  financial  statement  schedule  listed  in  Item  15(a)(2).  These  consolidated 
financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
these consolidated 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.  and  subsidiaries  at  December 31,  2004  and  2003,  and  the  consolidated  results  of  their  operations  and  their  cash
flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2004,  in  conformity  with  U.S.  generally  accepted  accounting 
principles. Also, in our opinion, the related 2004 financial statement schedule, when considered in relation to the basic consolidated
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),  the 
effectiveness of Mobile Mini, Inc.’s internal control over financial reporting as of December 31, 2004, based on criteria established in 
Internal Control(cid:650)Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our 
report dated March 10, 2005 expressed an unqualified opinion thereon.

MOBILE MINI, INC. 

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  (Mobile  Mini  or  the  Company),  is  a  leading  provider  of  portable  storage  solutions.    At
December 31, 2004, we have a fleet of portable storage and office units and operate throughout the United States and in one Canadian 
province.  Our portable storage products offer secure, temporary storage with immediate access.  We have a diversified client base, 
including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the United States military, 
hotels, restaurants, entertainment complexes and households.  Customers use our 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.

We have experienced rapid growth during the last several years.  This growth is primarily related to our internal growth at existing 
branch locations, as well as some growth through acquisitions of new branches. 

Our ability to obtain used containers for our lease fleet is subject in large part to the availability of these containers in the market.  This 
is in part subject to international trade issues and the demand for containers in the ocean cargo shipping business.  When international 
shipping  increases,  the  availability  of  used  ocean-going  containers  for  sale  often  decreases,  and  the  price  of  available  containers 
increases.  Conversely, an oversupply of used ocean-going containers may cause container prices to fall.  Our 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.  This would cause 
our  revenues  and  our  earnings  to  decline.    In  addition,  under  our  revolving  credit  facility,  we  are  required  to  comply  with  certain 
covenants and restrictions, as more fully discussed in Note 3.  If we fail to comply with these covenants and restrictions, the lender has 
the  right  to  refuse  to  lend  additional  funds  and  may  require  early  payment  of  amounts  owed.    If  this  happens,  it  would  materially 
impact our growth and ability to fund ongoing operations.  Furthermore, because a substantial portion of the amount borrowed under
the  credit  facility  bears  interest  at  a  variable  rate,  a  significant  increase  in  interest  rates  could  have  an  adverse  affect  on  our 
consolidated results of operations and financial condition. 

Principles of Consolidation  

The  consolidated  financial  statements  include  the  accounts  of  Mobile  Mini,  Inc.  and  its  wholly  owned  subsidiaries.    All  significant 
intercompany transactions have been eliminated.   

Reclassifications 

Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current 
financial presentation requirements.

Revenue Recognition 

In  December  2003,  the  Securities  and  Exchange  Commission  (SEC)  issued  staff  accounting  bulletin  No.  104  (SAB  104)  Revenue
Recognition, which codifies, revises and rescinds certain sections of Staff Accounting Bulletin No. 101 Revenue Recognition, in order 
to  make  this  interpretive  guidance  consistent  with  current  authoritative  accounting  guidance  and  SEC  rules  and  regulations.    The
changes noted in SAB 104 did not have a material effect on our consolidated financial statements.  Mobile Mini follows SAB 101,
Revenue Recognition in Financial Statements, as amended by SAB 104, for the recognition of revenue. 

Lease  and  leasing  ancillary  revenues  and  related  expenses  generated  under  portable  storage  units  and  office  units  are  recognized
monthly  which  approximates  a  straight-line  basis.    Revenues  and  expenses  from  portable  storage  unit  delivery  and  hauling  are 
recognized when these services are billed, in accordance with SAB 101, as amended by SAB 104.  Mobile Mini recognizes revenues 
from sales of containers and office units upon delivery.  

46

Cost of Sales 

Cost of sales in our consolidated statements of operations includes only the costs for units we sell.  Similar costs associated with the 
portable storage units that we lease are capitalized on our balance sheet under “Lease fleet”. 

Advertising Costs 

Advertising costs are accounted for under Statement of Position, (SOP) 93-7, Reporting on 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, 2003 and 2004, prepaid advertising costs
were  approximately  $2.8  million  and  $2.5  million,  respectively.    The  amortization  period  of  the  prepaid  balance  never  exceeds  12
months.    Our  direct-response  advertising  costs  are  monitored  by  each  branch  through  call  logs  and  advertising  source  codes  in  a
contact  management  information  system.    Advertising  expense  was  $6.2  million,  $6.9  million  and  $7.0  million  in  2002,  2003  and 
2004, respectively. 

Cash 

Our revolving credit agreement includes restrictions on excess cash.  There was no restricted cash at December 31, 2003 and 2004.

Receivables  

Receivables primarily consist of amounts due from customers from the lease or sale of containers.  Mobile Mini records an estimated
provision for bad debts and reviews the provision monthly for adequacy.  Specific accounts are written off against the allowance when 
management determines the account is uncollectible.  We require 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 Mobile Mini to concentrations of credit risk, as defined by SFAS No. 105, Disclosure 
of  Information  about  Financial  Instruments  with  Off-Balance-Sheet  Risk  and  Financial  Instruments  with  Concentrations  of  Credit 
Risk, consist primarily of receivables.  Concentration of credit risk with respect to receivables are limited due to the large number of 
customers spread over a large geographic area in many industry segments.  Receivables related to our sales operations are generally 
secured  by  the  product  sold  to  the  customer.    Receivables  related  to  our  leasing  operations  are  primarily  small  month-to-month 
amounts.  We have 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, refurbishment and maintenance, primarily for our lease 
fleet  and  our  units  held  for  sale.    Raw  materials  principally  consist  of  raw  steel,  wood,  glass,  paint,  vinyl  and  other  assembly
components used in our processes.  Inventories at December 31, consist of the following: 

Raw materials and supplies 
Work-in-process 
Finished portable storage units

Property, Plant and Equipment  

Property,  plant  and  equipment  are  stated  at  cost,  net  of  accumulated  depreciation.    Depreciation  is  provided  using  the  straight-line 
method over the assets’ estimated useful lives.  Residual values are determined when the property is constructed or acquired and range 

47

 
 
 
 
 
 
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.  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. 

Property, plant and equipment at December 31, consist of the following:

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

Other Assets and Intangibles 

Other  assets  and  intangibles  primarily  represent  deferred  financing  costs  and  intangible  assets  from  acquisitions  and  were 
approximately $7.1 million and $6.5 million, net of accumulated amortization of $0.7 million and $1.4 million at December 31, 2003
and 2004, respectively. 

Income Taxes 

The Company utilizes the liability method of accounting for income taxes as set forth in SFAS No. 109, Accounting for Income Taxes.
Under  the  liability  method,  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  

Mobile  Mini  has  adopted  SFAS  No.  128,  Earnings  per  Share.    Pursuant  to  SFAS  No.  128,  basic  earnings  per  common  share  are 
computed by dividing net income by the weighted average number of shares of common stock outstanding during the year.  Diluted 
earnings per common share are determined assuming the potential dilution of the exercise or conversion of options and warrants into 
common stock. 

Below are the required disclosures pursuant to SFAS No. 128 for the years ended December 31:

Employee stock options to purchase 518,550, 1,332,920 and 819,670 shares were issued or outstanding during 2002, 2003 and 2004,
respectively, but were not included in the computation of diluted earnings per share because the exercise price exceeded the average 
market  price  for  that  year  and  the  effect  would  have  been  anti-dilutive.    The  anti-dilutive  options  could  potentially  dilute  future 
earnings per share. 

Long-Lived Assets 

In accordance with SFAS No. 144, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed 
Of,” the Company 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.  We have not recognized any impairment losses during the three year period ended December 31, 2004.  

Goodwill 

On January 1, 2002, Mobile Mini adopted SFAS No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other Intangible 
Assets.    Purchase  prices  of  acquired  businesses  that  are  accounted  for  as  purchases  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.  

Prior  to  January  1,  2002,  Mobile  Mini  amortized  goodwill  over  the  useful  life of the underlying asset, not to exceed 25 years.   On 
January 1, 2002, Mobile Mini began accounting for goodwill under the provisions of SFAS Nos. 141 and 142 and discontinued the 
amortization of goodwill.  The Company evaluates goodwill periodically to determine whether events or circumstances have occurred
that  would  indicate  goodwill  might  be  impaired.    At  December 31,  2004,  Mobile  Mini  had  gross  goodwill  of  $55.1  million  and 
accumulated amortization of $2.0 million.  For the years ended December 31, 2002, 2003 and 2004, Mobile Mini did not recognize 
amortization expense related to goodwill.   

In  assessing  the  recoverability  of  Mobile  Mini’s  goodwill  and  other  intangibles,  Mobile  Mini  must  make  assumptions  regarding 
estimated  future  cash  flows  and  other  factors  to  determine  the fair value of the respective assets.  If these estimates or their related 
assumptions change in the future, Mobile Mini may be required to record impairment charges for these assets not previously recorded.
Some  factors  considered  important  which  could  trigger  an  impairment  review  include  significant  underperformance  relative  to 
expected historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy 
for the overall business, Mobile Mini’s market capitalization relative to net book value, and significant negative industry or economic 
trends.  

Mobile  Mini  performed  the  annual  required  impairment  tests  for  goodwill  as  of  December  31,  2003  and  2004  and  determined  that 
goodwill was not impaired either year and it was not necessary to record any impairment losses related to goodwill and other intangible 
assets.  

49

 
     
 
 
 
   
 
 
 
 
Fair Value of Financial Instruments  

We  determine  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 we 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 our borrowings under our credit facility and 
notes payable approximate fair value.  The fair values of our notes payable and credit facility are estimated using discounted cash flow 
analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements.  Based on the borrowing rates 
currently  available  to  us  for  bank  loans  with  similar  terms  and  average  maturities,  the  fair  value  of  fixed  rate  notes  payable  at
December 31, 2003 and 2004 approximated the book values.  The fair value of our $150.0 million 9.5% Senior Notes at December 31,
2003  and  2004  is  approximately  $165.0  million  and  $174.8  million,  respectively.    The  determination  for  fair  value  is  based  on  the 
latest sale prices at the end of each fiscal year obtained from a third-party institution.  

Deferred Financing Costs  

Included  in  other  assets  and  intangibles  are  deferred  financing  costs,  of  approximately  $6.2  million  and  $5.7  million,  net  of 
accumulated amortization of $0.4 million and $1.2 million at December 31, 2003 and 2004, respectively.  The costs associated with 
our former credit agreement were written off to expense in 2002 and the remaining costs of the new credit facility prior to amending 
the  agreement  in  June  2003,  were  written  off  to  expense  in  2003  (See  Note  3  –  Line  of  Credit).    The  costs  of  obtaining  long-term
financing, including our amended credit facility, are being amortized over the term of the related debt, using the straight-line method.  
Amortizing the deferred financing costs using the straight-line method approximates such costs using the effective interest method.  

Derivatives 

SFAS No. 133, Accounting For Derivative Instruments and Hedging Activities, amended by SFAS No. 137, Accounting for Derivative 
Instruments  and  Hedging  Activities  -  Deferral  of  the  Effective  Date  of  FASB  No.  133,  SFAS  No.  138,  Accounting  for  Certain 
Derivative Instruments and Certain Hedging Activities, and SFAS No. 149, Amendment of Statement 133 on Derivative Instruments 
and  Hedging  Activities  establishes  accounting  and  reporting  standards  requiring  that  every  derivative  instrument  (including  certain 
derivative instruments embedded in other contracts) be recorded in the balance sheet as either an asset or liability measured at its fair 
value.  The statement requires that changes in the fair value of the derivative be recognized currently in earnings unless specific hedge 
accounting criteria are met.  If specific hedge accounting criteria are met, changes in the fair value of derivatives will be recognized in 
other comprehensive loss until the hedged item is recognized in earnings.  The ineffective portion of a derivative’s change in fair value 
will  be  immediately  recognized  in  earnings.    Derivative  transactions  during  2003  and  2004  under  SFAS  No.  133  resulted  in 
comprehensive  income  of  $3.7  million,  net  of  income  tax  expense  of  $2.4  million  for  2003,  and  $0.3  million,  net  of  income  tax 
expense of $0.2 million for 2004.  Derivative transactions are included in other liabilities.  Accumulated other comprehensive income 
(loss) included a charge of approximately $293,000 and $33,000 related to derivatives at December 31, 2003 and 2004, respectively.   

Stock Based Compensation

We grant stock options for a fixed number of shares to employees and directors with an exercise price equal to the fair market value of 
the shares at the date of grant.  We account for such stock option grants using the intrinsic-value method of accounting in accordance 
with  Accounting  Principles  Board,  (APB),  Opinion  No.  25,  Accounting  for  Stock  Issued to  Employees  (No.  25)  and  related 
Interpretations.  Under APB No. 25, we generally recognize no compensation expense with respect to such awards.  Also, we do not
record any compensation expense in connection with our Employee Stock Option Plan. 

50

If  we  had  accounted  for stock options consistent with SFAS No. 123, these amounts would be amortized on a straight-line basis as
compensation  expense  over  the  average  holding  period  of  the  options  and  our  net  income  and  earnings  per  share  would  have  been 
reported as follows for the years ended December 31:

Pro forma results disclosed are based on the provisions of SFAS No. 123 using the Black-Scholes option valuation model and are not 
likely  to  be  representative  of  the  effects  on  pro  forma  net  income  for  future  years.   In addition, the Black-Scholes option valuation 
model  was  developed  for  use  in  estimating  the  fair  value  of  traded  options,  which  have  no  vesting  restrictions  and  are  fully 
transferable.  In addition, option valuation models require the input of highly subjective assumptions including the expected stock price 
volatility.  Because our stock options have characteristics significantly different from those of traded options, and because changes in 
the subjective input assumptions can materially affect the fair value estimate, in our opinion, the estimating models do not necessarily 
provide a reliable single measure of the fair value of our stock options.  See Note 8 for further discussion of the Company’s stock-
based employee compensation. 

Foreign Currency Translation and Transactions

For our Canadian operations, the local currency is the functional currency.  All assets and liabilities are translated into United States 
dollars  at  period-end  exchange  rates  and  all  income  statement  amounts  are  translated  at  the  average  exchange  rate  for  each  month
within the year.  Adjustments resulting from this translation are recorded in accumulated other comprehensive income.    

Use of Estimates  

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  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 

SFAS  No.  123,  (Revised  2004)  (SFAS  No.  123(R)),  Share-Based  Payment,  was  issued  in  December  2004.   SFAS  No.  123(R)  is  a 
revision  of  FASB Statement 123, Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25,  Accounting for 
Stock Issued to Employees, and its related implementation guidance, which allowed companies to use the intrinsic method of valuing 
share-based  payment  transactions.  SFAS  No.  123(R)  focuses  primarily  on  accounting  for  transactions  in  which  an  entity  obtains 
employee  services  in  share-based  payment  transactions.  SFAS  No.  123(R)  requires  a  public  entity  with  share-based  payments  to 
employees, including grants of employee stock options, to be recognized in the financial statements based on the fair-value method as 
defined in Statement 123. Pro forma disclosure is no longer an alternative.  That cost will be recognized over the period during which 
an employee is required to provide service in exchange for the award. This statement is effective as of the beginning of the first interim 
or annual reporting period that begins after June 15, 2005.

As permitted by Statement 123, we currently account for share-based payments to employees using the intrinsic value method and, as 
such,  generally  recognize  no  compensation  cost  for  employee  stock  options.    Accordingly,  the  adoption  of  Statement  123(R)’s  fair
value  method  is  expected  to  have  an  impact  on  our  results  of  operations,  although  it  will  have  no  impact  on  our  overall  financial
condition.  The impact upon adoption of Statement 123(R)  cannot be predicted at this time because it will depend on levels of share-
based payments granted in the future, the valuation model used to value the options and other variables. 

SFAS No. 123(R) permits public companies to adopt its requirements using one of two methods. A “modified prospective” method in
which compensation cost is recognized beginning with the effective date of SFAS No. 123(R) (a) based on the requirements of SFAS 
123(R) for all share-based payments granted after the effective date and (b) based on the requirements of Statement 123 for all awards 
granted to employees prior to the effective date of SFAS 123(R) that remain unvested on the effective date. A “modified retrospective” 
method  which  includes  the  requirements  of  the  modified  prospective  method  described  above,  but  also  permits entities  to  restate, 
based on the amounts previously recognized under Statement 123 for purposes of pro forma disclosures, either (a) all prior periods
presented or (b) prior interim periods of the year of adoption. The Company will determine which method that it will adopt prior to the 
effective date of SFAS No. 123(R). 

SFAS No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4, was issued in November 2004.  SFAS No. 151 clarifies 
that abnormal amounts of idle facility expense, freight, handling costs and spoilage should be expensed as incurred and not included in 
overhead.  Further, SFAS No. 151 requires that allocation of fixed and production facilities overheads to conversion costs should be 
based on normal capacity of the production facilities.  The provisions of SFAS No. 151 are effective for fiscal years beginning after 
June 15, 2005.  We do not expect the adoption of SFAS No. 151 to have a material effect on our results of operations or financial
condition. 

(2)  Lease Fleet:

Mobile Mini has a lease fleet primarily consisting of refurbished, 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  our  units’  estimated  useful  life,  after  the  date  we  put  the  unit  in  service,  and  are  depreciated  down  to  their  estimated 
residual  values.  Effective  January  1,  2004,  some  of  our  steel  units  were  in  our  fleet  longer  than  20  years  and  we  modified  our 
depreciation  policy  on  our  steel  units  to  an  estimated  useful  life  of  25  years  with  an  estimated  residual  value  of  62.5%  which 
effectively resulted in continual depreciation on these containers at the same annual rate as our previous depreciation policy of 20 year 
life and 70% residual value. Wood mobile office units are depreciated over 20 years down to a 50% residual value. Van trailers, which 
are a small part of our fleet, are depreciated over 7 years to a 20% residual value.  Van trailers 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.  We continue to evaluate these depreciation policies as more information becomes available from other 
comparable sources and our own historical experience.    At December 31, 2003 and 2004, all of our lease fleet units were pledged as 
collateral under the credit facility (see Note 3).  Normal repairs and maintenance to the portable storage and mobile office units are 
expensed as incurred. 

Gains from sale-leaseback transactions were deferred and amortized over the estimated useful lives of the related assets.  Unamortized
gains at December 31, 2003 and 2004, approximated $169,000 and $152,000, respectively, and are reflected as a reduction to the lease 
fleet value in the accompanying consolidated balance sheets.

(3)  Line Of Credit:

On  February  11,  2002,  we  entered  into  a  Loan  and  Security  Agreement  with  a  group  of  lenders,  led  by  Fleet  Capital  Corporation, 
which  provides  us  with  a  $250.0  million  revolving  credit  facility.    The  initial  borrowings  under  that  credit  facility  were  used  to 
refinance approximately $161.4 million of outstanding borrowings under a prior credit facility, which had a maturity date of March 
2004.  In connection with this refinancing, in the first quarter of 2002 we recorded an after-tax extraordinary charge (under SFAS No. 
4)  of  approximately  $0.8  million,  net  of  tax  of  $0.5  million,  which  has  been  reclassified  as  debt  restructuring  expense  in  the 
accompanying consolidated financial statements in accordance with SFAS No. 145.  The credit facility under the Loan and Security
Agreement was then scheduled to expire in February 2007. 

In June 2003, we amended and restated the credit agreement, which we refer hereinafter as the Loan and Security Agreement, to permit 
us to issue $150 million of our Senior Notes, to operate at higher levels of leverage and to reduce required fleet utilization covenant 
levels.    The  term  of  the  credit  facility  was  extended  by  one  year  to  February  2008.    In  January  2004,  we  amended  our  Loan  and 
Security  Agreement  such  that,  if  our  Board  of  Directors  were  to  adopt  a  stock  repurchase  plan,  we  would  be  permitted  under  the 
agreement to purchase in the open market an aggregate of up to $10.0 million of our common stock.  In March 2004, the Loan and 
Security Agreement was amended to permit further expansion of our lease fleet should there be a stronger demand, by changing our
minimum required fixed charge coverage ratio from 2.10 to 1.0 to 1.85 to 1.0.  In August 2004, our lenders agreed to further amend 
our Loan and Security Agreement to reduce the interest rate, which is a spread over LIBOR and varies based upon our ratio of funded 
debt to earnings before interest expense, taxes, depreciation and amortization and certain excluded expenses. 

Borrowings under the present Loan and Security Agreement are secured by a lien on substantially all of our present and future assets.  
Borrowings of up to $250 million are available under this facility, based on the value of our lease fleet, property, plant, equipment, and 
levels of inventories and receivables.  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 
we may borrow under this facility.  The interest rate spread under the facility is based on a quarterly calculation of our ratio of funded 
debt  to  earnings  before  interest  expense,  taxes,  depreciation  and  amortization  and  certain  excluded  expenses  during  the  prior  12
months.    Borrowings  are,  at  our  option,  at  either  a  spread from the prime or LIBOR rates, as defined.  At December 31, 2004, the
prime  rate  was  5.25%  and  the  weighted  average  LIBOR  rate  was  2.2291%.    The  Loan  and  Security  Agreement  contains  several 
covenants,  including  a  minimum  fixed  charge  coverage,  maximum  ratio  of  funded  debt  to  EBITDA  (as  defined  in  the  Loan  and 
Security  Agreement),  a  minimum  borrowing  base  availability  and  minimum  required  utilization  rates.    The  Loan  and  Security 
Agreement also restricts our capital expenditures, our incurrence of additional debt and prohibits our payment of cash dividends on the 
common stock.  We were in compliance with all covenants at December 31, 2004.  The most restrictive covenant is the ratio of funded 
debt to EBITDA, as defined in the Loan and Security Agreement, of 5.75 to 1.0 at December 31, 2004.  We had approximately $110.7
million of availability, at December 31, 2004, under the requirements of this covenant.  

Our revolving line of credit balance outstanding was approximately $89.0 million and $125.9 million at December 31, 2003 and 2004,
respectively.    Our  2003  balance  was  affected  by  our  issuance  of  $150.0 million of Senior Notes in June 2003.  (See Note 5).  The
weighted average interest rate under the line of credit, including the effect of applicable interest rate swaps, was approximately 5.4% in 
2003  and  4.8%  in  2004,  and  the  average  balance  outstanding  during  2003  and  2004  was  approximately  $152.6  million  and $113.9 
million, respectively. 

53

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In connection with our debt restructuring transaction on June 26, 2003, we terminated $110.0 million of the $135.0 million interest rate 
swap agreements then in effect.  The termination fees for unwinding these agreements of approximately $8.7 million are included in 
debt  restructuring  expense  in  the  accompanying  consolidated  financial  statements.    The  fixed  interest  rate  on  the  remaining  $25.0
million swap is 3.66% plus the spread.  Accounting for these swap agreements is covered by SFAS No. 133 and the aggregate change
in the fair value of the interest rate swap agreements resulted in comprehensive income at December 31, 2003 of $3.7 million, net of 
income tax expense of $2.4 million and at December 31, 2004, comprehensive income of $0.3 million, net of income tax expense of
$0.2  million.    These  swap  agreements  are  designated  as  cash  flow  hedges  and  interest  expense  on  the  borrowings  under  these 
agreements is accrued using the fixed rates identified in the swap agreements.  Our objective in entering into these swap transactions 
was to reduce the risk associated with future interest rate fluctuations.  We began accounting for the swap agreements under SFAS No. 
133 effective January 1, 2001.

In  June  2003,  we  completed  the  sale  of  $150.0  million  in  aggregate  principal  amount  of  9.5%  Senior  Notes  due  July  2013.    This 
transaction allowed us to replace floating rate debt with long term fixed rate debt and, through changes in covenants that we negotiated 
in our credit agreement, it greatly increased our borrowing availability.  The net proceeds from the sale of the Senior Notes were used 
to pay down borrowings under our revolving credit facility and to pay transaction costs and expenses.  The  Senior Notes bear interest 
at the rate of 9.5% per annum, which is payable semi annually in January and July each year. 

The  Senior  Notes  mature  on  July  1,  2013,  and  we  can  redeem  some  or  all  of  the  Notes  on  or  after  July  1,  2008,  at  their  principal
amount at specified redemption prices that range from 104.75% in 2008 to 100.00% in 2012 and thereafter, plus accrued and unpaid
interest to the date of the redemption.  In addition, on or prior to July 1, 2006, with proceeds that we may raise in one or more equity 
offerings, we can choose to redeem up to 35% of the outstanding Notes at a redemption price of 109.50% of the principal amount, plus 
accrued and unpaid interest thereon. 

(6)  Income Taxes:

We account for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes.  SFAS No. 109 requires the use of an 
asset and liability approach in accounting for income taxes.  Deferred tax assets and liabilities are recorded based on the differences 
between the financial statement and tax bases of assets and liabilities at the tax rates in effect when these differences are expected to 
reverse.

A reconciliation of the federal statutory rate to Mobile Mini’s effective tax rate for the years ended December 31, is as follows:

At December 31, 2004, we had a federal net operating loss carryforward of approximately $61.3 million which expires if unused from 
2009 to 2024.  At December 31, 2004, we had net operating loss carryforward in the various states in which we operate.  Deferred tax 
benefits are recorded for state net operating loss carryforwards only to the extent management estimates they are more than likely than 
not recoverable.

As a result of stock ownership changes during the years presented, it is possible that Mobile Mini has undergone one or more changes 
in  ownership  for  federal  income  tax  purposes,  which  can  limit  the  amount  of  net  operating  loss  currently  available  as  a  deduction.  
Such limitation could result in our being required to pay tax currently because only a portion of the net operating loss is available.   

(7)  Transactions with Related Parties:

When we were a private company prior to 1994, we leased some of our properties from entities controlled by our founder, Richard E. 
Bunger,  and  his  family  members.    These  related  party  leases  remain  in  effect.    We  lease  a  portion  of  the  property  comprising  our
Phoenix  location  and  the  property  comprising  our  Tucson  location  from  entities  owned  by  Steven  G.  Bunger  and  his  siblings 
(including Carolyn A. Clawson, a member of our board of directors).  Steven G. Bunger is our President and Chief Executive Officer
and has served as our Chairman of the Board since February 2001.  Annual lease payments under these leases totaled approximately 
$81,000, $83,000 and $84,000 in 2002, 2003 and 2004, respectively.  In 2003, the term of each of these leases was extended for five 
years, under the same terms and conditions, and expire on December 31, 2008.  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  and  Carolyn  A. 
Clawson.    Annual  lease  payments  in  2002,  2003  and  2004  under  this  lease  were  approximately  $247,000,  $252,000  and  $261,000, 
respectively.  The Rialto lease expires on April 1, 2016.  Management believes that the rental rates reflect the fair market rental value 
of these properties. 

Mobile  Mini  obtains  services  throughout  the  year  from  SkilQuest,  Inc.,  a  company  engaged  in  sales  and  management  support 
programs.    SkilQuest,  Inc.  is  owned  by  Carolyn  A.  Clawson,  a  member  of  our  board  of  directors.    Mobile  Mini  made  aggregate 
payments of approximately $263,000, $334,000, and $188,000 to SkilQuest, Inc. in 2002, 2003 and 2004, respectively, which Mobile
Mini believes represented the fair market value for the services performed.

In  February  2001,  Mobile  Mini  and  its  former  Chairman  of  the  Board,  Richard  E.  Bunger,  entered  into  an  employment  agreement 
pursuant to which Mr. Bunger provides services to Mobile Mini during the term of the agreement, which is scheduled to end on June 
30, 2005.  Under the agreement, Mobile Mini paid Mr. Bunger $180,000 during 2002, $112,000 during 2003 and $12,000 in 2004, 
and  will  pay  him  $1,000  per  month  through  June  30,  2005.    Until  February  2004,  Mobile  Mini    also  provided  office  space  and an 
administrative  assistant  to  Mr.  Bunger.    The  agreement  also  provides  that  Mr.  Bunger  is  bound  by  an  agreement  pertaining  to 
confidentiality of Mobile Mini’s confidential information, and a non-competition agreement.  

It is Mobile Mini’s intention not to enter  into any additional related party transactions other than extension of lease agreements and

Stock Option Plans

In  August  1994,  our  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,  2004,  there  were  outstanding    options  to  acquire
274,832 shares under the 1994 Plan.  In August 1999, our board of directors approved the Mobile Mini, Inc. 1999 Stock Option Plan, 
under  which  1.2  million  shares  of  common  stock  were  originally  reserved  for  issuance  upon  the  exercise  of  options  which  may  be 
granted under this plan.  The 1999 Plan was amended in 2003, to increase shares of common stock authorized for issuance from 1.2
million to 2.2 million shares.  Both plans and amendments were approved  by the stockholders at annual meetings.  Under the 1999
Plan, both incentive stock options (ISOs), which are intended to meet the requirements of Section 422 of the Internal Revenue Code,
and  non-qualified  stock  options  may  be  granted.    ISOs  may  be  granted  to  our  officers  and  other  employees.    Non-qualified  stock 
options may be granted to directors and employees, and to non-employee service providers.  The purposes of the Plan 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, our management and other employees.  The board of directors believes that stock options are important to attract and to 
encourage the continued employment and service of officers and other employees by facilitating their purchase of a stock interest in 
Mobile Mini. 

The option exercise price for all options granted under the Plan 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  the  Plan  may  be  made  either  in  cash  or,  if  permitted  by  the  particular  option  agreement,  by 
exchanging  shares  of  common  stock  with  a  fair  market  value  equal  to  the  total  option  exercise  price  plus  cash  for  any  difference.
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  Plan  is  administered  by  the  compensation  committee  of  our  board  of  directors.    The  committee  is  comprised  of  independent 
directors.    They  determine  whether  options  will  be  granted,  whether  options  will  be  ISOs  or  non-qualified  options,  which  officers, 
employees  and  service  providers  will be granted options, the vesting schedule for options and the number of options to be granted.
Each option granted must expire no more than 10 years from the date it is granted.  Each non-employee director serving on our board
of directors receives an automatic grant of options for 7,500 shares on August 1 of each year as part of the compensation we provide to 
such directors. 

The  board  of  directors  may  amend  the  1999  Plan  at  any  time,  except  that  approval  by  our  stockholders  may  be  required  for  an 
amendment  that  increases  the  aggregate  number  of  shares  which  may  be  issued  pursuant  to  the  plan,  changes  the  class  of  persons 
eligible to receive ISO’s, 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 the 
plan.  The board of directors may terminate or suspend the 1999 Plan at any time.  Unless previously terminated, the 1999 Plan will 
expire  in  August  2009.    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.

On  December  13,  2000,  the  compensation  committee  extended  the  term  of  10,000  stock  options  granted  to  Steven  G.  Bunger,  our 
President and Chief Executive Officer, that were to expire on December 29, 2000.  The options were originally granted at an exercise 
price of $4.13 per share and were extended for five years with a two year vesting period.  These options will now expire on December 
29,  2005.    In  connection  with  this  transaction,  we  amortized  the  expense  over  the  pro  rata  vesting  period  of  two  years  which 
approximated $76,000 in both 2001 and 2002. 

We account for stock-based compensation plans under APB No. 25, under which no compensation expense has been recognized in the 
accompanying consolidated financial statements for stock-based employee awards with an exercise price equal to or greater than the 
fair value of the common stock on the date of grant.  For purposes of SFAS No. 123, the fair value of each option granted has been 
estimated at the date of the grant using the Black-Scholes option pricing model using the following assumptions: 

2002

2003 

2004 

Risk free interest rates range 
Expected holding period 
Dividend rate 
Expected volatility 

3.03 to 4.81%
5.0 years

5.0 years 
0.0% 
35.6% 

3.47 to 3.53% 
5.4 years 
0.0% 
37.6% 

Under these assumptions, the weighted average fair value of the stock options granted was $9.63, $8.26 and $11.20 for 2002, 2003 and 
2004, respectively.   

The effect of applying SFAS No. 123 in the pro forma disclosures above is not likely to be representative of the effect on reported net 
income or earnings per share for future years, because options vest over several years, additional stock options are generally awarded 
in each year and SFAS No. 123 has not been applied to options granted prior to January 1, 1995.

In 1995, we established a contributory retirement plan, 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 contributes 10% of employees’ contributions up to a maximum of $500 per employee.  We made 
matching  contributions  of  $72,000,  $76,000  and  $88,000  in  2002,  2003  and  2004,  respectively.    Additionally,  we  incurred 
approximately $25,000, $25,000 and $18,000 in 2002, 2003 and 2004, respectively, for administrative costs on this program. 

(9)  Commitments and Contingencies:

Leases 

As discussed more fully in Note 7, Mobile Mini is obligated under noncancellable operating leases with related parties.  We also lease 
our  corporate  offices  and  other  properties  and  operating  equipment  from  third  parties  under  noncancellable  operating  leases.    Rent 
expense under these agreements was approximately $4,224,000, $5,165,000 and $5,812,000 for the years ended December 31, 2002, 
2003 and 2004, respectively.  Total future commitments under all noncancellable agreements for the years ended December 31, are
approximately as follows:

Insurance 

We maintain all major lines of insurance coverage for our operations and employees with appropriate aggregate, per occurrence and 
deductible limits as we reasonably determine 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 our loss control 
efforts.  Our employee group health insurance program is a minimum premium plan.  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, even favorably, based on our actual experience at the end of the plan policy periods based on 
the carrier’s loss predictions and our historical claims data.  

Our  worker’s  compensation,  auto  and  general  liability  insurance  is  purchased  under  large  deductible  programs.    Our  current  per 
incident deductibles are: worker’s compensation $250,000, auto $100,000 and general liability $100,000.  We expense 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. 

In connection with the issuance of our insurance policies, we have provided our various insurance carriers approximately $3.3 million 
in letters of credit and an agreement under which we are contingently responsible for $1.2 million to provide credit support for our 
payment of the deductibles and/or loss limitation reimbursements under the insurance policies. 

General Litigation  

Mobile Mini 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 us and damage alleged to have occurred during delivery and pick-up of containers. We carry 
insurance to protect us against loss from these types of claims, subject to deductibles under the policy.  We do not believe that any of 
these  incidental  claims,  individually  or  in  the  aggregate,  is  likely  to  have  a  material  adverse  effect  on  our  business  or  results  of 
operations. 

(10)  Stockholders’ Equity:

Redeemable Warrants

Redeemable Warrants to purchase 187,500 shares of common stock at $5.00 per share were issued in connection with our issuance in
November 1997 of Senior Subordinated Notes.  Redeemable Warrants of 44,007 had been exercised for an equal number of shares of 
common stock, with proceeds to Mobile Mini of approximately $220,000 in 2002.  The Redeemable Warrants expired on November 1, 
2002, with 4,150 warrants expiring unexercised.   

(11)  Acquisitions:

Mobile Mini enters new markets in one of two ways, either by a new branch start up or through acquiring the portable storage assets 
and related leases of other companies.  An acquisition provides us with cash flow which enables us to immediately cover the overhead 
cost at the new branch.  On occasion, we also purchase portable storage businesses in areas where we have existing smaller branches 
either as part of multi-market acquisitions or in order to increase our operating margins at those branches. 

Mobile  Mini  acquired  for  cash,  the  assets  and  assumed  certain  liabilities  of  10  businesses  in  2002,  one  business  in  2003  and  one
business in 2004.  The accompanying consolidated financial statements include the operations of the acquired business from the date of 
acquisition.    The  acquisition  was  accounted  for  as  a  purchase  in  accordance  with  SFAS  No.  141,  Business  Combinations,  and 

59

accordingly,  the  purchased  assets  and  the  assumed  liabilities  were  recorded  at  their  estimated  fair  values  at  the  date  of  acquisition.  
Goodwill for acquisitions completed through June 30, 2001, was amortized using the straight-line method over 25 years from the date 
of the acquisition during 2001.  In 2002, 2003 and 2004, goodwill for acquisitions was not amortized in accordance with SFAS No.
142.  Goodwill was approximately $52.5 million and $53.1 million at December 31, 2003 and 2004 respectively.   

The aggregate purchase price of the operations acquired consists of:  

Cash 
Retirement of debt

The fair value of the assets purchased has been allocated as follows:

The purchase prices for acquisitions have been allocated to the assets acquired and liabilities assumed based upon estimated fair values 
as  of  the  acquisition  dates  and  are  subject  to  adjustment  when  additional  information  concerning  asset  and  liability  valuations  are 
finalized.  We do not believe any adjustments to the allocation will have any material effect on our results of operations or financial 
position. 

Included in other assets and intangibles are non-compete agreements that are amortized from 2 to 5 years using the straight-line method 
with no residual value.  Amortization expense for non-compete agreements was approximately $201,000, $244,000 and $207,000 in 
2002, 2003 and 2004, respectively.   .

(12)  Segment Reporting:

Our management approach includes evaluating each segment on which operating decisions are made based on performance, results and
profitability.  Currently, our branch operation is the only segment that concentrates on our core business of leasing.  Each branch has 
similar economic characteristics covering all products leased or sold, including the same customer base, sales personnel, advertising, 
yard  facilities,  general  and  administrative  costs  and  the  branch  management.    Management’s  allocation  of  resources,  performance
evaluations and operating decisions are not dependent on the mix of a branch’s products.  We do 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 includes the leasing and sales of portable storage units, portable offices and combination units configured for both 
storage and office space.  We lease to businesses and consumers in the general geographic area relative to each branch.  The operation 
includes Mobile Mini’s manufacturing facilities, which are responsible for the purchase, manufacturing and refurbishment of products 
for leasing, sales or equipment additions to our delivery system.   

60

 
 
 
 
 
 
 
 
 
 
 
 
 
 
In managing our business, we focus on our internal growth rate in leasing revenue, which we define as growth in lease revenues on a 
year over year basis at our branch locations in operation for at least one year, without inclusion of same market acquisitions.

In addition, we focus on earnings per share and on adjusted EBITDA.  We calculate this number by first calculating EBITDA, which is 
a measure of our earnings before interest expense, debt restructuring costs, income tax, depreciation and amortization.  This measure 
eliminates the effect of financing transactions that we enter into on an irregular basis based on capital needs and market opportunities.  
It provides us with a means to measure internally generated available cash from which we can fund our interest expense and our lease 
fleet growth.  In comparing EBITDA from year to year, we typically ignore the effect of what we consider non-recurring events not 
related to our core business operations to arrive at adjusted EBITDA.  The only such non-recurring event during the last several years 
has been the expenses that we incurred in connection with our litigation in Florida in Nuko Holdings I, LLC v. Mobile Mini, which 
was concluded in 2003; these expenses included the costs of defending in the lawsuit and the cost of the judgment. 

Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in 
such a manner; therefore, based on the provisions of SFAS No. 131, reportable segment information is the same as contained in our 
consolidated financial statements. 

(13)  Selected Consolidated Quarterly Financial Data (unaudited): 

The following table sets forth certain unaudited selected consolidated financial information for each of the four quarters in fiscal 2003 
and 2004.  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,  that  management  considers  necessary  for  a  fair  presentation  when  read  in  conjunction  with  the  Consolidated  Financial
Statements and notes.  The Company believes these comparisons of consolidated quarterly selected financial data are not necessarily 
indicative of future performance. 

Quarterly  earnings  per  share  may  not  total  to  the  fiscal  year  earnings  per  share  due  to  the  weighted  average  number  of  shares 
outstanding at the end of each period reported.

(2)  Includes termination expenses for certain interest rate swap agreements and certain capitalized debt issuance costs, both incurred

approximated $6.4 million, net of income tax benefit of $4.0 million, or $0.44 per diluted share. 

(3)  Includes Florida litigation expenses, which approximated $0.09 million, net of income tax benefit of $0.06 million, or $0.01 per

(5)  Includes  Florida  litigation  expenses,  which  approximated  $5.0  million,  net  of  income  tax  benefit  of  $3.2  million,  or  $0.35  per

diluted share. 

(14)   Subsequent Event: 

In January 2005, we entered into an interest rate swap agreement under which we effectively fixed the interest rate payable on $25.0
million of borrowings under our credit facility so that the rate is based upon a spread from a fixed rate, rather than a spread from the 
LIBOR rate. 

On  February  23,  2005,  the  Compensation  Committee  of  Mobile  Mini,  Inc.,  approved  the  accelerated  vesting  of  a  portion  of  the 
Company’s stock options granted on December 13, 2001, at an exercise price of $32.91 per share.  All of the stock options that were 
scheduled  to  vest  on  June  13,  2006,  approximately  83,100  shares  unvested  and  outstanding,  were  accelerated.    At  the  time  of  the 
resolution, the exercise price was less than the market value of those related common stock options.  Upon our adoption of SFAS No. 
123(R), the accelerated vesting will reduce future compensation expense to be recognized in the income statement over the next two 
years by approximately $1.5 million, or approximately $0.75 million in the second half of fiscal 2005 and approximately $0.75 million 
in the first half of fiscal 2006. 

(15)  Subsequent Event – Florida Litigation:  (unaudited) 

On  March  15,  2005,  Mobile  Mini  entered  into  a  Mediation  Conference  Memorandum,  pursuant  to  which  a  third  party  agreed  to 
reimburse  us  $3.3  million  of  the  loss  we  sustained  in  connection  with  two  lawsuits  that  arose  in  connection  with  our  acquisition  in 
April 2000 of a portable storage business in Florida.  These lawsuits were previously reported in our reports on Form 10-K and Form 
10-Q,  which  are  filed  with  the  Securities  and  Exchange  Commission.    The  settlement  is  subject  to  execution  and  delivery  of  a 
definitive settlement agreement containing the agreed-upon terms no later than April 14, 2005. 

ITEM 9.   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. 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

Under  the  supervision  and  with  the  participation  of  our  management,  including  our  Chief  Executive  Officer  and  Chief  Financial 
Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as such 
term  is  defined  under  Rule  13a-15(e)  and  15d-15(e)  promulgated  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the 
Exchange Act).  Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure 
controls  and  procedures,  subject  to  the  limitations  as  noted  below,  were  effective  during the period and as of the end of the period 
covered by this annual report.   

Because of its inherent limitations, our disclosure controls and procedures may not prevent or detect misstatements.  A control system, 
no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the controls 
system are met.  Because of the inherent limitations in all controls systems, no evaluation of controls can provide absolute assurance 
that all control issues and instances of fraud, if any, have been detected.

Changes in Internal Control Over Financial Reporting 

There were no changes in the Company’s internal controls over financial reporting that occurred during the year ended December 31,
2004,  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  the  Company’s  internal  control  over  financial
reporting. 

The Sarbanes-Oxley Act of 2002 (the Act) imposed many requirements regarding corporate governance and financial reporting.  One
requirement under section 404 of the Act is for management to report on the Company’s internal control over financial reporting and 
for  our  independent  registered  public  accountants  to attest to this report.  Management’s Report on Internal Control Over Financial
Reporting  and  our  Independent  Registered  Public  Accounting  Firm’s  report  with  respect  to  management’s  assessment  of  the 
effectiveness of internal control over financial reporting are included in Item 8, “Financial Statements and Supplementary Data”.
