Summary of MOBILE MINI INC

Item 2.02. Results of Operations and Financial Condition
On February 26, 2009, Mobile Mini, Inc. issued a press release announcing its financial results for the fourth quarter and fiscal year ended December 31, 2008. A copy of the press release is furnished as Exhibit 99.1 to this report. The press release includes the financial measures "EBITDA", "EBITDA margin" and "free cash flow." These measurements may be deemed a "non-GAAP financial measure" under rules of the Securities and Exchange Commission, including Regulation G. This non-GAAP financial information may be determined or calculated differently by other companies.
EBITDA is defined as net income before interest expense, income taxes, depreciation and amortization, and debt restructuring or extinguishment costs. The GAAP financial measure that is most directly comparable to EBITDA is net cash provided by operating activities. EBITDA margin is calculated by dividing consolidated EBITDA by total revenues. The GAAP financial measure that is most directly comparable to EBITDA Margin is operating margin, which represents operating income divided by revenues. We present EBITDA and EBITDA margin because we believe they provide useful information regarding our ability to meet our future debt payment requirements, capital expenditures and working capital requirements and that it provides an overall evaluation of our financial condition. In addition, EBITDA is a component of certain financial covenants under our revolving credit facility and is used to determine our available borrowing ability and the interest rate in effect at any point in time. We include EBITDA in the earnings announcement to provide transparency to investors. EBITDA has certain limitations as an analytical tool and should not be used as a substitute for net income, cash flows, or other consolidated income or cash flow data prepared in accordance with generally accepted accounting principles in the United States or as a measure of our profitability or our liquidity. EBITDA margin is presented along with the operating margin so as not to imply that more emphasis should be placed on it than the corresponding GAAP measure.
Free cash flow is defined as net cash provided by operating activities, less net cash used in investing activities, excluding acquisitions. Free cash flow is a non-GAAP financial measure and is not intended to replace net cash provided by operating activities, the most directly comparable GAAP financial measure. We present free cash flow because we believe it provides useful information regarding our liquidity and ability to meet our short-term obligations. In particular, free cash flow indicates the amount of cash available after capital expenditures for, among other things, investments in the Company's existing businesses, debt service obligations and strategic acquisitions.
A reconciliation of EBITDA to net cash provided by operating activities and net income to EBITDA, as well as a reconciliation of net cash provided by operating activities to free cash flow, follows. These reconciliations are in thousands and include effects of rounding:
