SALT LAKE CITY, April 29, 2013 — Extra Space Storage Inc. (NYSE: EXR) (the “Company”), a leading owner and operator of self-storage properties in the United States, announced operating results for the three months ended March 31, 2013.

Highlights for the three months ended March 31, 2013:

·                  Achieved funds from operations (“FFO”) of $0.46 per diluted share, representing a 39.4% increase in FFO compared to the first quarter of 2012.

·                  Increased same-store revenue and net operating income (“NOI”) by 7.5% and 10.8%, respectively, compared to the same period in 2012.

·                  Increased same-store occupancy by 290 basis points to 88.6% at March 31, 2013, compared to 85.7% as of March 31, 2012.

·                  Acquired two properties and added 55 properties to the Company’s third-party management platform.

·                  Paid a quarterly dividend of $0.25 per share.

Spencer F. Kirk, CEO of Extra Space Storage Inc., commented:  “We experienced another strong quarter.  Solid operational performance and record high occupancies have once again helped produce outstanding financial results.  Disciplined growth continues to enhance our results as we have benefited from recent acquisitions and the growth of our third-party management platform.  We are optimistic and have confidence in our people, our technology and our properties as we enter peak rental season.”

FFO Per Share:

The following table outlines the Company’s FFO and FFO as adjusted for the three months ended March 31, 2013 and 2012.  The table also provides a reconciliation to GAAP net income per diluted share for each period presented (amounts shown in thousands, except share data - unaudited):

For the three months ended March 31, 2013, there was no dilutive impact from lease-up development properties to FFO or FFO as adjusted per diluted share, compared to $0.01 for the same period in 2012.

Operating Results and Same-Store Property Performance:

The following table outlines the Company’s same-store property performance for the three months ended March 31, 2013 and 2012 (amounts shown in thousands, except property count data - unaudited):

Revenues for the three months ended March 31, 2013, were up primarily due to increases in occupancy and rental rates for both new and existing customers.  Expenses were slightly higher for the same period due to increases in payroll, property tax and credit card expenses.  These increases were offset by lower advertising, office and utility expenses.

The Company’s major markets with revenue growth above the portfolio average for the three months ended March 31, 2013, included Chicago, Cincinnati, Denver, Los Angeles and San Diego.  Major markets performing below the Company’s portfolio average included Sacramento, Phoenix and Washington D.C.

Acquisition and Third-Party Management Activity:

During the quarter, the Company acquired two properties for an approximate purchase price of $12.9 million.  These properties are located in Illinois and Maryland, and were acquired as a result of the purchase of a partner’s interest in two existing joint ventures.

The Company has five additional properties under contract for a total of approximately $53.6 million.  These properties are located in Hawaii, Maryland, North Carolina and Texas.  The purchase of these properties is expected to close by the end of the second quarter of 2013.  These acquisitions are subject to due diligence and other customary closing conditions and no assurance can be provided that these acquisitions will be completed on the terms described, or at all.

During the quarter, the Company added 55 properties to its management program.  As of March 31, 2013, the Company managed 236 properties for third-party owners.  Including 279 properties owned and operated in joint ventures, the Company had a total of 515 properties under management.  The Company continues to be the largest self-storage management company in the United States.

Balance Sheet:

As of March 31, 2013, the Company’s percentage of fixed-rate debt to total debt was 80.2%. The weighted average interest rate on the Company’s fixed and variable rate debt was 4.6% and 2.3%, respectively.  The combined weighted average interest rate was 4.1% with a weighted average maturity of approximately 5.6 years.

Dividends:

The Company paid a first quarter dividend of $0.25 per share on the common stock of the Company on March 29, 2013, to stockholders of record at the close of business on March 15, 2013.

Outlook:

The Company currently estimates that FFO per diluted share will be between $0.47 and $0.49 for the quarter ending June 30, 2013, and will be between $1.94 and $2.01 for the year ending December 31, 2013.  FFO estimates for the year are fully diluted for an estimated average number of shares and Operating Partnership units (“OP units”) outstanding during the year.  The Company’s estimates are forward-looking and based on management’s view of current and future market conditions.

The Company’s actual results may differ materially from these estimates, which include the following annual assumptions:

Forward-Looking Statements:

Certain information set forth in this release contains “forward-looking statements” within the meaning of the federal securities laws. Forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as “believes,” “estimates,” “expects,” “may,” “will,” “should,” “anticipates,” or “intends,” or the negative of such terms or other comparable terminology, or by discussions of strategy. We may also make additional forward-looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements.  There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this release.  Any forward-looking statements should be considered in light of the risks referenced in the “Risk Factors” section included in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q.  Such factors include, but are not limited to:

·                  adverse changes in general economic conditions, the real estate industry and the markets in which we operate;

·                  the effect of competition from new and existing self-storage facilities or other storage alternatives, which could cause rents and occupancy rates to decline;

·                  difficulties in our ability to evaluate, finance, complete and integrate acquisitions and developments successfully and to lease up those properties, which could adversely affect our profitability;

·                  potential liability for uninsured losses and environmental contamination;

·                  the impact of the regulatory environment as well as national, state, and local laws and regulations including, without limitation, those governing REITs, which could increase our expenses and reduce our cash available for distribution;

·                  disruptions in credit and financial markets and resulting difficulties in raising capital or obtaining credit at reasonable rates or at all, which could impede our ability to grow;

·                  increased interest rates and operating costs;

·                  reductions in asset valuations and related impairment charges;

·                  the failure of our joint venture partners to fulfill their obligations to us or their pursuit of actions that are inconsistent with our objectives;

·                  the failure to maintain our REIT status for federal income tax purposes;

·                  economic uncertainty due to the impact of war or terrorism, which could adversely affect our business plan; and

·                  difficulties in our ability to attract and retain qualified personnel and management members.

All forward-looking statements are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but there can be no assurance that management’s expectations, beliefs and projections will result or be achieved. All forward-looking statements apply only as of the date made. We undertake no obligation to publicly update or revise forward-looking statements which may be made to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.

Definition of FFO:

FFO provides relevant and meaningful information about the Company’s operating performance that is necessary, along with net income and cash flows, for an understanding of the Company’s operating results. The Company believes FFO is a meaningful disclosure as a supplement to net earnings. Net earnings assume that the values of real estate assets diminish predictably over time as reflected through depreciation and amortization expenses.  The values of real estate assets fluctuate due to market conditions and the Company believes FFO more accurately reflects the value of the Company’s real estate assets.  FFO is defined by the National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) as net income computed in accordance with U.S. generally accepted accounting principles (“GAAP”), excluding gains or losses on sales of operating properties and impairment write downs of depreciable real estate assets, plus depreciation and amortization and after adjustments to record unconsolidated partnerships and joint ventures on the same basis. The Company believes that to further understand the Company’s performance, FFO should be considered along with the reported net income and cash flows in accordance with GAAP, as presented in the Company’s consolidated financial statements.

For informational purposes, the Company provides FFO as adjusted for the exclusion of non-recurring revenues and expenses, acquisition related costs and non-cash interest charges related to the Company’s exchangeable senior notes.  Although the Company’s calculation of FFO as adjusted differs from NAREIT’s definition of FFO and may not be comparable to that of other REITs and real estate companies, the Company believes it provides a meaningful supplemental measure of operating performance.  The Company believes that by excluding non-recurring revenues and expenses, the costs related to acquiring properties and non-cash interest charges from the exchangeable senior notes, stockholders and potential investors are presented with an indicator of its operating performance that more closely achieves the objectives of the real estate industry in presenting FFO.  FFO as adjusted by the Company should not be considered a replacement of the NAREIT definition of FFO and may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.  FFO does not represent cash generated from operating activities determined in accordance with GAAP, and should not be considered as an alternative to net income as an indication of the Company’s performance, as an alternative to net cash flow from operating activities as a measure of liquidity, or as an indicator of the Company’s ability to make cash distributions.

Definition of Same-Store Properties:

The Company’s same-store properties for the periods presented consist of 344 properties that are wholly-owned and operated and that were stabilized by the first day of the earliest calendar year presented.  The Company considers a property to be stabilized once it has been open three years or has sustained average square foot occupancy of 80.0% or more for one calendar year.  Same-store results provide information relating to property operations without the effects of acquisitions or completed developments and should not be used as a basis for future same-store performance or for the performance of the Company’s properties as a whole.
