1. ORGANIZATION

Extra Space Storage Inc. (the “Company”) is a fully-integrated, self-administered and self-managed real estate investment trust (“REIT”), formed as a Maryland corporation on April 30, 2004, to own, operate, manage, acquire, develop and redevelop professionally managed self-storage properties (“stores”) located throughout the United States. The Company continues the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. The Company’s interests in its stores is held through its operating partnership, Extra Space Storage LP (the “Operating Partnership”), which was formed on May 5, 2004. The Company’s primary assets are general partner and limited partner interests in the Operating Partnership. This structure is commonly referred to as an umbrella partnership REIT (“UPREIT”). The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. To the extent the Company continues to qualify as a REIT, it will not be subject to tax, with certain limited exceptions, on the taxable income that is distributed to its stockholders.

The Company invests in stores by acquiring wholly-owned stores or by acquiring an equity interest in real estate entities. At March 31, 2015, the Company had direct and indirect equity interests in 835 stores. In addition, the Company managed 271 stores for third parties, bringing the total number of stores which it owns and/or manages to 1,106. These stores are located in 35 states, Washington, D.C. and Puerto Rico.

The Company operates in three distinct segments: (1) rental operations; (2) tenant reinsurance; and (3) property management, acquisition and development. The rental operations activities include rental operations of stores in which we have an ownership interest. No single tenant accounts for more than 5.0% of rental income. Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in the Company’s stores. The Company’s property management, acquisition and development activities include managing, acquiring, developing and selling stores.

2. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information, and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they may not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2015, are not necessarily indicative of results that may be expected for the year ending December 31, 2015. The condensed consolidated balance sheet as of December 31, 2014 has been derived from the Company’s audited financial statements as of that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the Securities and Exchange Commission.

Reclassifications

Certain amounts in the Company’s 2014 consolidated financial statements and supporting note disclosures have been reclassified to conform to the current period presentation. Such reclassifications did not impact previously reported net income or accumulated deficit.

Recently Issued Accounting Standards

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and disclosures of Components of an Entity.” Under this guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. The guidance also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The Company adopted this guidance effective January 1, 2015. The Company has not previously had discontinued operations and as such, does not expect this guidance to have a significant impact on its consolidated financial statements.

Table of Contents

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards. ASU 2014-09 outlines a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016, and early adoption is prohibited. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. Management is currently assessing the impact of the adoption of ASU 2014-09 on the Company’s condensed consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which requires a reporting entity to treat a performance target that affects vesting, and that could be achieved after the requisite service period, as a performance condition. ASU 2014-12 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. ASU 2014-12 may be adopted either prospectively for share-based payment awards granted or modified on or after the effective date, or retrospectively, using a modified retrospective approach. The modified retrospective approach would apply to share-based payment awards outstanding as of the beginning of the earliest annual period presented in the financial statements on adoption, and to all new or modified awards thereafter. The Company does not expect the adoption of ASU 2014-12 to have a material impact on its consolidated financial statements.

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. ASU 2015-02 amends the criteria for determining if a service provider possesses a variable interest in a VIE, and eliminates the presumption that a general partner should consolidate a limited partnership. The Company does not expect the adoption of this standard to materially impact its consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” This guidance requires debt issuance costs related to a recognized debt liability to be presented as a direct deduction from the carrying amount of that debt liability. The new guidance will only impact financial statement presentation. The guidance is effective in the first quarter of 2016 and allows for early adoption. The Company does not expect the adoption of this standard to materially impact its consolidated financial statements.

3. FAIR VALUE DISCLOSURES

Derivative Financial Instruments

Currently, the Company uses interest rate swaps to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate forward curves.

The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. In conjunction with the Financial Accounting Standards Board’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, as of March 31, 2015, the Company had assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety were classified in Level 2 of the fair value hierarchy.

Table of Contents

The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2015, aggregated by the level in the fair value hierarchy within which those measurements fall.

There were no transfers of assets and liabilities between Level 1 and Level 2 during the three months ended March 31, 2015. The Company did not have any significant assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of March 31, 2015 or December 31, 2014.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Long-lived assets held for use are evaluated for impairment when events or circumstances indicate there may be impairment. The Company reviews each store at least annually to determine if any such events or circumstances have occurred or exist. The Company focuses on stores where occupancy and/or rental income have decreased by a significant amount. For these stores, the Company determines whether the decrease is temporary or permanent, and whether the store will likely recover the lost occupancy and/or revenue in the short term. In addition, the Company carefully reviews stores in the lease-up stage and compares actual operating results to original projections.

When the Company determines that an event that may indicate impairment has occurred, the Company compares the carrying value of the related long-lived assets to the undiscounted future net operating cash flows attributable to the assets. An impairment loss is recorded if the net carrying value of the assets exceeds the undiscounted future net operating cash flows attributable to the assets. The impairment loss recognized equals the excess of net carrying value over the related fair value of the assets.

When real estate assets are identified by management as held for sale, the Company discontinues depreciating the assets and estimates the fair value of the assets, net of selling costs. If the estimated fair value, net of selling costs, of the assets that have been identified as held for sale is less than the net carrying value of the assets, a valuation allowance is established. The operations of assets held for sale or sold during the period are presented as part of normal operations for all periods presented.

The Company assesses whether there are any indicators that the value of the Company’s investments in unconsolidated real estate ventures may be impaired annually and when events or circumstances indicate that there may be impairment. An investment is impaired if management’s estimate of the fair value of the investment is less than its carrying value. To the extent impairment has occurred, and is considered to be other than temporary, the loss is measured as the excess of the carrying amount of the investment over the fair value of the investment.

In connection with the Company’s acquisition of stores, the purchase price is allocated to the tangible and intangible assets and liabilities acquired based on their fair values, which are estimated using significant unobservable inputs. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Intangible assets, which represent the value of existing tenant relationships, are recorded at their fair values based on the avoided cost to replace the current leases. The Company measures the value of tenant relationships based on the rent lost due to the amount of time required to replace existing customers, which is based on the Company’s historical experience with turnover in its stores. Debt assumed as part of an acquisition is recorded at fair value based on current interest rates compared to contractual rates. Acquisition-related transaction costs are expensed as incurred.

Fair Value of Financial Instruments

The carrying values of cash and cash equivalents, restricted cash, receivables, other financial instruments included in other assets, accounts payable and accrued expenses, variable-rate notes payable, lines of credit and other liabilities reflected in the condensed consolidated balance sheets at March 31, 2015 and December 31, 2014 approximate fair value.

The fair values of the Company’s notes receivable from Preferred Operating Partnership unit holders were based on the discounted estimated future cash flows of the notes (categorized within Level 3 of the fair value hierarchy); the discount rate used approximated the current market rate for loans with similar maturities and credit quality. The fair values of the Company’s fixed-rate notes payable

Table of Contents

and notes payable to trusts were estimated using the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality. The fair value of the Company’s exchangeable senior notes was estimated using an average market price for similar securities obtained from a third party.

The fair values of the Company’s fixed-rate assets and liabilities were as follows for the periods indicated:

4. EARNINGS PER COMMON SHARE

Basic earnings per common share is computed using the two-class method by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding during the period. All outstanding unvested restricted stock awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common stockholders; accordingly, they are considered participating securities that are included in the two-class method. Diluted earnings per common share measures the performance of the Company over the reporting period while giving effect to all potential common shares that were dilutive and outstanding during the period. The denominator includes the weighted average number of basic shares and the number of additional common shares that would have been outstanding if the potential common shares that were dilutive had been issued, and is calculated using either the two-class, treasury stock or as if-converted method, whichever is most dilutive. Potential common shares are securities (such as options, convertible debt, Series A Participating Redeemable Preferred Units (“Series A Units”), Series B Redeemable Preferred Units (“Series B Units”), Series C Convertible Redeemable Preferred Units (“Series C Units”), Series D Redeemable Preferred Units (“Series D Units”) and common Operating Partnership units (“OP Units”)) that do not have a current right to participate in earnings of the Company but could do so in the future by virtue of their option, redemption or conversion right.

In computing the dilutive effect of convertible securities, net income is adjusted to add back any changes in earnings in the period associated with the convertible security. The numerator also is adjusted for the effects of any other non-discretionary changes in income or loss that would result from the assumed conversion of those potential common shares. In computing diluted earnings per common share, only potential common shares that are dilutive (those that reduce earnings per common share) are included. For the three months ended March 31, 2015 and 2014, options to purchase approximately 19,762 and 18,100 shares of common stock, respectively, were excluded from the computation of earnings per share as their effect would have been anti-dilutive.

The following table presents the number of Preferred Operating Partnership units, and the potential common shares, that were excluded from the computation of earnings per share as their effect would have been anti-dilutive, assuming full conversion at the average share price for the quarter of $65.59.

Table of Contents

The Operating Partnership had $250,000 of its 2.375% Exchangeable Senior Notes due 2033 (the “Notes”) issued and outstanding as of March 31, 2015. The Notes could potentially have a dilutive impact on the Company’s earnings per share calculations. The Notes are exchangeable by holders into shares of the Company’s common stock under certain circumstances per the terms of the indenture governing the Notes. The exchange price of the Notes was $55.62 per share as of March 31, 2015, and could change over time as described in the indenture. The Company has irrevocably agreed to pay only cash for the accreted principal amount of the Notes relative to its exchange obligations, but retained the right to satisfy the exchange obligation in excess of the accreted principal amount in cash and/or common stock.

Though the Company has retained that right, Accounting Standards Codification (“ASC”) 260, “Earnings per Share,” requires an assumption that shares would be used to pay the exchange obligation in excess of the accreted principal amount, and requires that those shares be included in the Company’s calculation of weighted average common shares outstanding for the diluted earnings per share computation. For the three months ended March 31, 2015, 682,502 shares related to the Notes were included in the computation for diluted earnings per share. For the three months ended March 31, 2014, no shares related to the Notes were included in the computation for diluted earnings per share as the exchange price exceeded the per share price of the Company’s common stock during this period.

For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series A Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the positive intent and ability to settle at least $115,000 of the instrument in cash (or net settle a portion of the Series A Units against the related outstanding note receivable), only the amount of the instrument in excess of $115,000 is considered in the calculation of shares contingently issuable for the purposes of computing diluted earnings per share as allowed by ASC 260-10-45-46.

For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series B Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series B Units outstanding as of March 31, 2015 of $41,902 by the closing price of the Company’s common stock as of March 31, 2015 of $67.57 per share. Assuming full exchange for common shares as of March 31, 2015, 620,127 shares would have been issued to the holders of the Series B Units.

For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series C Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series C Units outstanding as of March 31, 2015 of $29,639 by the closing price of the Company’s common stock as of March 31, 2015 of $67.57 per share. Assuming full exchange for common shares as of March 31, 2015, 438,641 shares would have been issued to the holders of the Series C Units.

For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series D Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series D Units outstanding as of March 31, 2015 of $13,710 by the closing price of the Company’s common stock as of March 31, 2015 of $67.57 per share. Assuming full exchange for common shares as of March 31, 2015, 202,901 shares would have been issued to the holders of Series D Units.

5. STORE ACQUISITIONS

The following table summarizes the Company’s acquisitions of operating stores for the three months ended March 31, 2015, and does not include purchases of raw land or improvements made to existing assets:

6. VARIABLE INTERESTS

The Operating Partnership has three wholly-owned unconsolidated subsidiaries (“Trust,” “Trust II” and “Trust III,” together, the “Trusts”) that have issued trust preferred securities to third parties and common securities to the Operating Partnership. The proceeds from the sale of the preferred and common securities were loaned in the form of notes to the Operating Partnership. The Trusts are VIEs because the holders of the equity investment at risk (the trust preferred securities) do not have the power to direct the activities of the entities that most significantly affect the entities’ economic performance because of their lack of voting or similar rights. Because the Operating Partnership’s investment in the Trusts’ common securities was financed directly by the Trusts as a result of its loan of the proceeds to the Operating Partnership, that investment is not considered an equity investment at risk. The Operating Partnership’s investment in the Trusts is not a variable interest because equity interests are variable interests only to the extent that the investment is considered to be at risk, and therefore the Operating Partnership cannot be the primary beneficiary of the Trusts. Since the Company is not the primary beneficiary of the Trusts, they have not been consolidated. A debt obligation has been recorded in the form of notes for the proceeds as discussed above, which are owed to the Trusts. The Company has also included its investment in the Trusts’ common securities in other assets on the condensed consolidated balance sheets.

The Company has not provided financing or other support during the periods presented to the Trusts that it was not previously contractually obligated to provide. The Company’s maximum exposure to loss as a result of its involvement with the Trusts is equal to the total amount of the notes discussed above less the amounts of the Company’s investments in the Trusts’ common securities. The net amount is the notes payable that the Trusts owe to third parties for their investments in the Trusts’ preferred securities.

Following is a tabular comparison of the liabilities the Company has recorded as a result of its involvement with the Trusts to the maximum exposure to loss the Company is subject to as a result of such involvement as of March 31, 2015:

The Company had no consolidated VIEs during the three months ended March 31, 2015.

7. DERIVATIVES

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its debt funding and by using derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposure that arises from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (“OCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. A portion of these changes is excluded from accumulated other comprehensive income as it is allocated to noncontrolling interests. During the three months ended March 31, 2015 and 2014, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt.

The Company held 23 derivative financial instruments which had a total combined notional amount of $825,987 as of March 31, 2015.

Fair Values of Derivative Instruments

The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the condensed consolidated balance sheets:

Effect of Derivative Instruments

The tables below present the effect of the Company’s derivative financial instruments on the condensed consolidated statements of operations for the periods presented. No tax effect has been presented as the derivative instruments are held by the Company:

Credit-risk-related Contingent Features

The Company has agreements with some of its derivative counterparties that contain provisions pursuant to which the Company could be declared in default of its derivative obligations if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender.

The Company also has an agreement with some of its derivative counterparties that incorporates the loan covenant provisions of the Company’s indebtedness with a lender affiliate of the derivative counterparty. Failure to comply with the loan covenant provisions would result in the Company being in default on any derivative instrument obligations covered by the agreement.

As of March 31, 2015, the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of March 31, 2015, it could have been required to settle its obligations under the agreements at their termination value of $7,740, including accrued interest.

8. EXCHANGEABLE SENIOR NOTES

On June 21, 2013, the Operating Partnership issued $250,000 of its 2.375% Exchangeable Senior Notes due 2033 at a 1.5% discount, or $3,750. Costs incurred to issue the Notes were approximately $1,672. These costs are being amortized as an adjustment to interest expense over five years, which represents the estimated term based on the first available redemption date, and are included in other assets in the condensed consolidated balance sheets. The Notes are general unsecured senior obligations of the Operating Partnership and are fully guaranteed by the Company. Interest is payable on January 1 and July 1 of each year beginning January 1, 2014, until the maturity date of July 1, 2033. The Notes bear interest at 2.375% per annum and contain an exchange settlement feature, which provides that the Notes may, under certain circumstances, be exchangeable for cash (for the principal amount of the Notes) and, with respect to any excess exchange value, for cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at the Company’s option. The exchange rate of the Notes as of March 31, 2015 was approximately 17.98 shares of the Company’s common stock per $1,000 principal amount of the Notes.

The Operating Partnership may redeem the Notes at any time to preserve the Company’s status as a REIT. In addition, on or after July 5, 2018, the Operating Partnership may redeem the Notes for cash, in whole or in part, at 100% of the principal amount plus accrued and unpaid interest, upon at least 30 days but not more than 60 days prior written notice to the holders of the Notes. The holders of the Notes have the right to require the Operating Partnership to repurchase the Notes for cash, in whole or in part, on July 1 of the years 2018, 2023 and 2028, and upon the occurrence of certain designated events, in each case for a repurchase price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest. Certain events are considered “Events of Default,” as defined in the indenture governing the Notes, which may result in the accelerated maturity of the Notes.

Table of Contents

GAAP requires entities with convertible debt instruments that may be settled entirely or partially in cash upon conversion to separately account for the liability and equity components of the instrument in a manner that reflects the issuer’s economic interest cost. The Company therefore accounts for the liability and equity components of the Notes separately. The equity component is included in additional paid-in capital in stockholders’ equity in the condensed consolidated balance sheets, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component. The discount is being amortized as interest expense over the remaining period of the debt through its first redemption date, July 1, 2018. The effective interest rate on the liability component is 4.0%.

Information about the carrying amount of the equity component, the principal amount of the liability component, its unamortized discount and its net carrying amount was as follows for the periods indicated:

9. NONCONTROLLING INTEREST REPRESENTED BY PREFERRED OPERATING PARTNERSHIP UNITS

Classification of Noncontrolling Interests

GAAP requires a company to present ownership interests in subsidiaries held by parties other than the company in the consolidated financial statements within the equity section, but separate from the company’s equity. It also requires the amount of consolidated net income attributable to the parent and to the noncontrolling interest to be clearly identified and presented on the face of the consolidated statement of operations and requires changes in ownership interest to be accounted for similarly as equity transactions. If noncontrolling interests are determined to be redeemable, they are to be carried at their redemption value as of the balance sheet date and reported as temporary equity.

The Company has evaluated the terms of the Operating Partnership’s preferred units and classifies the noncontrolling interest represented by such preferred units as stockholders’ equity in the accompanying condensed consolidated balance sheets. The Company will periodically evaluate individual noncontrolling interests for the ability to continue to recognize the noncontrolling interest as permanent equity in the condensed consolidated balance sheets. Any noncontrolling interests that fail to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount and (2) the redemption value as of the end of the period in which the determination is made.

Series A Participating Redeemable Preferred Units

On June 15, 2007, the Operating Partnership entered into a Contribution Agreement with various limited partnerships affiliated with AAAAA Rent-A-Space to acquire ten stores in exchange for 989,980 Series A Units of the Operating Partnership. The stores are located in California and Hawaii.

On June 25, 2007, the Operating Partnership loaned the holders of the Series A Units $100,000. The note receivable bears interest at 4.85% per annum. During 2013, a loan amendment was signed extending the maturity date to September 1, 2020. The loan is secured by the borrower’s Series A Units. The holders of the Series A Units could redeem up to 114,500 Series A Units prior to the maturity date of the loan. If any redemption in excess of 114,500 Series A Units occurs prior to the maturity date, the holder of the Series A Units is required to repay the loan as of the date of that redemption.

Table of Contents

The partnership agreement of the Operating Partnership (as amended, the “Partnership Agreement”) provides for the designation and issuance of the Series A Units. The Series A Units will have priority over all other partnership interests of the Operating Partnership with respect to distributions and liquidation.

Under the Partnership Agreement, Series A Units in the amount of $115,000 bear a fixed priority return of 5% and have a fixed liquidation value of $115,000. The remaining balance participates in distributions with, and has a liquidation value equal to, that of the OP Units. The Series A Units are redeemable at the option of the holder, which redemption obligation may be satisfied, at the Company’s option, in cash or shares of its common stock.

On October 3, 2014, the holders of the Series A Units redeemed 114,500 Series A Units for $4,794 in cash and 280,331 shares of common stock. No additional redemption of Series A Units can be made without repayment of the loan. Subsequent to this redemption, the fixed priority return is calculated using the current liquidation value of $101,699. The Series A Units are shown on the balance sheet net of the $100,000 loan because the borrower under the loan receivable is also the holder of the Series A Units.

Series B Redeemable Preferred Units

On April 3, 2014, the Operating Partnership completed the purchase of a store located in Georgia. This store was acquired in exchange for $15,158 of cash and 333,360 Series B Units valued at $8,334.

On August 29, 2013, the Operating Partnership completed the purchase of 19 out of 20 stores affiliated with All Aboard Mini Storage, all of which are located in California. On September 26, 2013, the Operating Partnership completed the purchase of the remaining store. These stores were acquired in exchange for $100,876 of cash (including $98,960 of debt assumed and immediately defeased at closing), 1,342,727 Series B Units valued at $33,568, and 1,448,108 OP Units valued at $62,341.

The Partnership Agreement provides for the designation and issuance of the Series B Units. The Series B Units rank junior to the Series A Units, on parity with the Series C Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation.

The outstanding Series B Units have a liquidation value of $25.00 per unit for a fixed liquidation value of $41,902. Holders of the Series B Units receive distributions at an annual rate of 6%. These distributions are cumulative. The Series B Units will become redeemable at the option of the holder on the first anniversary of the date of issuance, which redemption obligation may be satisfied at the Company’s option in cash or shares of its common stock.

Series C Convertible Redeemable Preferred Units

On November 19, 2013, the Company entered into Contribution Agreements with various entities affiliated with Grupe Properties Co. Inc. (“Grupe”), under which the Company agreed to acquire twelve stores, all of which are located in California. The Company completed the purchase of these stores between December 2013 and May 2014. The Company previously held 35% interests in five of these stores and a 40% interest in one store through six separate joint ventures with Grupe. These stores were acquired in exchange for a total of approximately $45,722 of cash, the assumption of $37,532 in existing debt, and the issuance of 704,016 Series C Units valued at $30,960.

The Partnership Agreement provides for the designation and issuance of the Series C Units. The Series C Units rank junior to the Series A Units, on parity with the Series B Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation.

The outstanding Series C Units have a liquidation value of $42.10 per unit for a fixed liquidation value of $29,639. From issuance to the fifth anniversary of issuance, each Series C Unit holder will receive quarterly distributions equal to the quarterly distribution per OP Unit plus $0.18. Beginning on the fifth anniversary of issuance, each Series C Unit holder will receive a fixed quarterly distribution equal to the aggregate quarterly distribution payable in respect of such Series C Unit during the four quarters immediately preceding the fifth anniversary of issuance, divided by four. These distributions are cumulative. The Series C Units will become redeemable at the option of the holder one year from the date of issuance, which redemption obligation may be satisfied at the

20

Table of Contents

Company’s option in cash or shares of its common stock. The Series C Units will also become convertible into OP Units at the option of the holder one year from the date of issuance, at a rate of 0.9145 OP Units per Series C Unit converted. This conversion option expires upon the fifth anniversary of the date of issuance.

In December 2014, the Operating Partnership loaned certain holders of the Series C Units $20,230. The notes receivable, which are collateralized by the Series C Units, bear interest at 5.0% per annum and mature on December 15, 2024. The Series C Units are shown on the balance sheet net of the $20,230 loan because the borrower under the loan receivable is also the holder of the Series C units.

Series D Redeemable Preferred Units

In December 2014, the Operating Partnership completed the acquisition of a store located in Florida. This store was acquired in exchange for $5,621 in cash and 548,390 Series D Units valued at $13,710.

The Partnership Agreement provides for the designation and issuance of the Series D Units. The Series D Units rank junior to the Series A Units, on parity with the Series B Units and Series C Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation.

The Series D Units have a liquidation value of $25.00 per unit, for a fixed liquidation value of $13,710. Holders of the Series D Units receive distributions at an annual rate of 5.0%. These distributions are cumulative. The Series D Units will become redeemable at the option of the holder on the first anniversary of the date of issuance, which redemption obligation may be satisfied at the Company’s option in cash or shares of its common stock.

10. NONCONTROLLING INTEREST IN OPERATING PARTNERSHIP

The Company’s interest in its stores is held through the Operating Partnership. ESS Holding Business Trust I, a wholly-owned subsidiary of the Company, is the sole general partner of the Operating Partnership. ESS Holding Business Trust II, also a wholly-owned subsidiary of the Company, is a limited partner of the Operating Partnership. Between its general partner and limited partner interests, the Company held a 93.4% ownership interest in the Operating Partnership as of March 31, 2015. The remaining ownership interests in the Operating Partnership (including Preferred Operating Partnership units) of 6.6% are held by certain former owners of assets acquired by the Operating Partnership.

The noncontrolling interest in the Operating Partnership represents OP Units that are not owned by the Company. In conjunction with the formation of the Company, and as a result of subsequent acquisitions, certain persons and entities contributing interests in stores to the Operating Partnership received limited partnership interests in the form of OP Units. Limited partners who received OP Units in the formation transactions or in exchange for contributions for interests in stores have the right to require the Operating Partnership to redeem part or all of their OP Units for cash based upon the fair market value of an equivalent number of shares of the Company’s common stock (based on the ten-day average trading price) at the time of the redemption. Alternatively, the Company may, in its sole discretion, elect to acquire those OP Units in exchange for shares of its common stock on a one-for-one basis, subject to anti-dilution adjustments provided in the Partnership Agreement. The ten-day average closing stock price at March 31, 2015 was $67.76 and there were 4,365,879 OP Units outstanding. Assuming that all of the OP Unit holders exercised their right to redeem all of their OP Units on March 31, 2015 and the Company elected to pay the OP Unit holders cash, the Company would have paid $295,832 in cash consideration to redeem the units.

GAAP requires a company to present ownership interests in subsidiaries held by parties other than the company in the consolidated financial statements within the equity section, but separate from the company’s equity. It also requires the amount of consolidated net income attributable to the parent and to the noncontrolling interest to be clearly identified and presented on the face of the consolidated statement of operations, and requires changes in ownership interest to be accounted for similarly as equity transactions. If noncontrolling interests are determined to be redeemable, they are to be carried at their redemption value as of the balance sheet date and reported as temporary equity.

The Company has evaluated the terms of the OP Units and classifies the noncontrolling interest represented by the OP Units as stockholders’ equity in the accompanying condensed consolidated balance sheets. The Company will periodically evaluate individual noncontrolling interests for the ability to continue to recognize the noncontrolling amount as permanent equity in the condensed consolidated balance sheets. Any noncontrolling interests that fail to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount and (2) the redemption value as of the end of the period in which the determination is made.

11. OTHER NONCONTROLLING INTERESTS

Other noncontrolling interests represent the ownership interests of various third parties in two consolidated joint ventures as of March 31, 2015. One of these consolidated joint ventures owns a single store in California. The second consolidated joint venture owns 19 stores. The ownership interests of the third-party owners range from 1.0% to 3.3%. Other noncontrolling interests are included in the stockholders’ equity section of the Company’s condensed consolidated balance sheets. The income or losses attributable to these third-party owners based on their ownership percentages are reflected in net income allocated to Operating Partnership and other noncontrolling interests in the condensed consolidated statements of operations.

12. EQUITY IN EARNINGS OF UNCONSOLIDATED REAL ESTATE VENTURES—GAIN ON SALE OF REAL ESTATE AND PURCHASE OF JOINT VENTURE PARTNERS’ INTERESTS

In March 2015, ESS PRISA II LLC (“PRISA II”), a joint venture in which the Company holds a 2.0% interest, sold one store located in New York for $90,000. As a result of the sale, PRISA II recognized a gain of $60,496 and the Company recorded its 2.0% portion of the gain, or $1,228.

In March 2015, the Company acquired its joint venture partner’s 82.4% interest in Sacramento One, an existing joint venture which owned one store located in California, for $1,700. In addition, the Company held mortgage notes receivable from Sacramento One totaling $11,009, which were eliminated as a result of the acquisition. Prior to the acquisition, the remaining 17.6% interest was owned by the Company, which accounted for its investment in Sacramento One using the equity method. The Company recorded a non-cash gain of $1,629 related to this transaction, which represents the increase in fair value of the company’s interest in the joint venture from its formation to the acquisition date.

13. SEGMENT INFORMATION

The Company operates in three distinct segments: (1) rental operations; (2) tenant reinsurance; and (3) property management, acquisition and development. Management fees collected for wholly-owned stores are eliminated in consolidation. Financial information for the Company’s business segments is presented below:

CAUTIONARY LANGUAGE

The following discussion and analysis should be read in conjunction with our unaudited “Condensed Consolidated Financial Statements” and the “Notes to Condensed Consolidated Financial Statements (unaudited)” appearing elsewhere in this report and the “Consolidated Financial Statements,” “Notes to Consolidated Financial Statements” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in our Form 10-K for the year ended December 31, 2014. We make statements in this section that are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this Form 10-Q entitled “Statement on Forward-Looking Information.”

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based on our unaudited condensed consolidated financial statements contained elsewhere in this report, which have been prepared in accordance with GAAP. Our notes to the unaudited condensed consolidated financial statements contained elsewhere in this report and the audited financial statements contained in our Form 10-K for the year ended December 31, 2014 describe the significant accounting policies essential to our unaudited condensed consolidated financial statements. Preparation of our financial statements requires estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions that we have used are appropriate and correct based on information available at the time they were made. These estimates, judgments and assumptions can affect our reported assets and liabilities as of the date of the financial statements, as well as the reported revenues and expenses during the period presented. If there are material differences between these estimates, judgments and assumptions and actual facts, our financial statements may be affected.

In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require our judgment in its application. There are areas in which our judgment in selecting among available alternatives would not produce a materially different result, but there are some areas in which our judgment in selecting among available alternatives would produce a materially different result. See the notes to the unaudited condensed consolidated financial statements that contain additional information regarding our accounting policies and other disclosures.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT, formed to continue the business commenced in 1977 by Extra Space Storage LLC and its subsidiaries to own, operate, manage, acquire, develop and redevelop professionally managed self-storage stores.

We derive substantially all of our revenues from rents received from tenants under leases at each of our wholly-owned stores; from management fees on the stores we manage for joint venture partners and unaffiliated third parties; and from our tenant reinsurance program. Our management fee is equal to approximately 6% of cash collected from the managed stores. We also receive an asset management fee of 0.5% of the total asset value from one of our joint ventures.

We operate in competitive markets, often where consumers have multiple stores from which to choose. Competition has impacted, and will continue to impact, our store results. We experience seasonal fluctuations in occupancy levels, with occupancy levels generally higher in the summer months due to increased moving activity. Our operating results depend materially on our ability to lease available self-storage units and actively manage rental rates, and on the ability of our tenants to make required rental payments. We believe that we are able to respond quickly and effectively to changes in local, regional and national economic conditions by centrally adjusting rental rates through the combination of our revenue management team and our industry-leading technology systems.

We continue to evaluate a range of new initiatives and opportunities in order to enable us to maximize stockholder value. Our strategies to maximize stockholder value include the following:

PROPERTIES

As of March 31, 2015, we owned, had ownership interests in, or managed 1,106 stores in 35 states, Washington, D.C. and Puerto Rico. Of these 1,106 stores, we owned 565 stores, we held joint venture interests in 270 stores, and our taxable REIT subsidiary, Extra Space Management, Inc., operated an additional 271 stores that are owned by third parties. These operating stores contain approximately 81.8 million square feet of rentable space in approximately 740,000 units.

Our stores are generally situated in convenient, highly visible locations clustered around large population centers such as Atlanta, Baltimore/Washington, D.C., Boston, Chicago, Dallas, Houston, Las Vegas, Los Angeles, Miami, New York City, Orlando, Philadelphia, Phoenix, St. Petersburg/Tampa and San Francisco/Oakland. These areas all enjoy above-average population growth and income levels. The clustering of assets around these population centers enables us to reduce our operating costs through economies of scale. Our acquisitions and management business have given us an increased scale in many core markets as well as a foothold in many markets where we had no previous presence.

We consider a store to be in the lease-up stage after it has been issued a certificate of occupancy, but before it has achieved stabilization. We consider a store to be stabilized once it has achieved either an 80% average occupancy rate for a full year measured as of January 1, or has been open for three years.

As of March 31, 2015, approximately 670,000 tenants were leasing storage units at the 1,106 operating stores that we own and/or manage, primarily on a month-to-month basis, providing the flexibility to increase rental rates over time as market conditions permit. Existing tenants generally receive rate increases at least annually, for which no direct correlation has been drawn to our vacancy trends. Although leases are short-term in duration, the typical tenant tends to remain at our stores for an extended period of time. For stores that were stabilized as of March 31, 2015, the average length of stay was approximately 13.4 months for tenants that vacated during the preceding twelve month period.

The average annual rent per square foot for our existing customers at stabilized stores, net of discounts and bad debt, was $14.18 for the three months ended March 31, 2015, compared to $13.62 for the same period ended March 31, 2014. Average annual rent per square foot for new leases was $14.56 for the three months ended March 31, 2015, compared to $13.82 for the same period ended March 31, 2014. The average discounts, as a percentage of rental revenues, during these periods were 3.9% and 4.1%, respectively.

Our store portfolio is made up of different types of construction and building configurations depending on the site and the municipality where it is located. Most often sites are what we consider “hybrid” stores, a mix of drive-up and multi-floor buildings. We have a number of multi-floor buildings with elevator access only, and a number of stores featuring ground-floor access only.

The following table presents additional information regarding the occupancy of our stabilized stores by state as of March 31, 2015 and 2014. The information as of March 31, 2014 is on a pro forma basis as though all the stores owned and/or managed at March 31, 2015 were under our control as of March 31, 2014.
