STATEMENT ON FORWARD-LOOKING INFORMATION
Certain information set forth in this report 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 developments, 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.
All forward-looking statements, including without limitation, management’s examination of historical operating trends and estimates of future earnings, 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.
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 report. Any forward-looking statements should be considered in light of the risks referenced in “Part II. Item 1A. Risk Factors” below and in “Part I. Item 1A. Risk Factors” included in our most recent Annual Report on Form 10-K. 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;
potential liability for uninsured losses and environmental contamination;
our ability to recover losses under our insurance policies;
the impact of the regulatory environment as well as national, state, and local laws and regulations including, without limitation, those governing real estate investment trusts (“REITs”), tenant reinsurance and other aspects of our business, which could adversely affect our results;
the effect of competition from new and existing stores or other storage alternatives, including increased or unanticipated competition for our properties, which could cause rents and occupancy rates to decline;
failure to close pending acquisitions and developments on expected terms, or at all;
risks associated with acquisitions, dispositions and development of properties, including increased development costs due to additional regulatory requirements related to climate change and other factors;
reductions in asset valuations and related impairment charges;
our reliance on information technologies, which are vulnerable to, among other things, attack from computer viruses and malware, hacking, cyberattacks and other unauthorized access or misuse, any of which could adversely affect our business and results;
impacts from any outbreak of highly infectious or contagious diseases, including reduced demand for self-storage space and ancillary products and services such as tenant reinsurance, and potential decreases in occupancy and rental rates and staffing levels, which could adversely affect our results;
economic uncertainty due to the impact of natural disasters, war or terrorism, which could adversely affect our business plan;
our lack of sole decision-making authority with respect to our joint venture investments;
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;
availability of financing and capital, the levels of debt that we maintain and our credit ratings;
changes in global financial markets and increases in interest rates;
the effect of recent or future changes to U.S. tax laws; and
the failure to maintain our REIT status for U.S. federal income tax purposes.
All forward-looking statements are based upon our beliefs, assumptions and expectations of our future performance, taking into account all information currently available to us. These beliefs, assumptions and expectations are subject to risks and uncertainties and can change as a result of many possible events or factors, not all of which are known to us. If a change occurs, our business, financial condition, liquidity and results of operations may vary materially from those expressed in our forward-looking statements. You should carefully consider these risks before you make an investment decision with respect to

our securities. 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.

1. ORGANIZATION
Extra Space Storage Inc. (the “Company”) is a fully integrated, self-administered and self-managed REIT, formed as a Maryland corporation on April 30, 2004, to own, operate, manage, acquire, develop and redevelop self-storage properties (“stores”) located throughout the United States. The Company was formed to continue the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. The Company’s interest 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, which meets the definition of a variable interest entity and is consolidated. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT.
The Company invests in stores by acquiring wholly-owned stores or by acquiring an equity interest in real estate entities. At September 30, 2025, the Company had direct and indirect equity interests in 2,427 stores. In addition, the Company managed 1,811 stores for third parties, bringing the total number of stores which it owns and/or manages to 4,238 . These stores are located in 43 states and Washington, D.C. The Company offers tenant reinsurance at its owned and managed stores that insures the value of goods in the storage units and also offers bridge loan financing to certain third-party self-storage owners for whom it manages properties.
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 and nine months ended September 30, 2025 are not necessarily indicative of results that may be expected for the year ending December 31, 2025. The condensed consolidated balance sheet as of December 31, 2024 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, 2024, as filed with the Securities and Exchange Commission.
Recently Issued Accounting Standards
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07 – “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” . The amended guidance requires the disclosure of incremental segment information, including significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and a reconciliation of segment profit or loss to net income. The title and position of the CODM must also be disclosed, along with how the CODM uses the reported measures to assess segment performance and to allocate resources. Pursuant to this ASU, the footnotes to the Company’s condensed consolidated financial statements include incremental disclosures related to its two reportable segments: (1) self-storage operations and (2) tenant reinsurance. The Company has adopted this standard as of December 31, 2024. Refer to note 15 for further discussion of the Company’s reportable segments.
In December 2023, the FASB issued ASU No. 2023-09 – “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” . The amended guidance focuses on providing more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. Pursuant to this ASU, the footnotes to the Company’s consolidated financial statements may include incremental disclosures related to income taxes. This standard is effective for annual periods beginning after December 15, 2024; therefore, compliance with this ASU will be required beginning with the Company’s annual report on Form 10-K for the year ending December 31, 2025, with early adoption permitted. The Company expects to adopt this ASU for its annual report on Form 10-K for the year ending December 31, 2025, is continuing to research the impact of this amended guidance, and does not expect this standard to have a material impact on its consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03 – “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)”. The guidance requires the disclosure of additional information related to certain costs and expenses, including amounts of inventory purchases, employee compensation, and depreciation and amortization included in each income statement line item. For any remaining items within each relevant expense caption, entities must provide a qualitative description of the nature of those expenses. The guidance also requires disclosure of the total amount of selling expenses and the entity’s definition of selling expenses. The guidance is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027; therefore, compliance with this ASU will be required beginning with the Company’s annual report on Form 10-K for the year ending December 31, 2027. The guidance may be applied prospectively or retrospectively, and early adoption is permitted. The Company is currently evaluating the impact of this ASU on 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 FASB’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 itself and its counterparties. However, as of September 30, 2025, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety were classified in Level 2 of the fair value hierarchy.
The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of September 30, 2025, aggregated by the level in the fair value hierarchy within which those measurements fall.
Fair Value Measurements at Reporting Date Using
Description Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3)
Other assets - Cash flow hedge swap agreements $ $ 5,327 $
Other liabilities - Cash flow hedge swap agreements $ $ 2,603 $
The Company did not have any significant assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of September 30, 2025 or December 31, 2024.

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, including the Company’s assumptions about the use of the asset, 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 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. The Company compares the carrying value of the related long-lived assets to their estimated fair value, supported by current third-party appraisal or broker market data (categorized within Level 3 of the fair value hierarchy). If the estimated fair value, net of selling costs, is less than the net carrying value of the assets, the Company would recognize a loss on the assets held for sale. The operations of assets held for sale or sold during the period are presented as part of normal operations. As of September 30, 2025, the Company had 29 stores classified as held for sale which are included in real estate assets, net. Refer to note 4 for additional details on disposition and held for sale activity.
The Company assesses annually whether there are any indicators that the value of the Company’s investments in unconsolidated real estate entities may be impaired 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.
The Company evaluates goodwill for impairment at least annually and whenever events, circumstances, and other related factors indicate that the fair value of the related reporting unit may be less than the carrying value. If the fair value of the reporting unit is determined to exceed the aggregate carrying amount, no impairment charge is recorded. Otherwise, an impairment charge is recorded for the amount in which the carrying value of the reporting unit exceeds the fair value. No impairments of goodwill were recorded for any period presented herein.
Fair Value of Financial Instruments
The carrying values of cash and cash equivalents, restricted cash, receivables, investments in debt securities and notes receivable, accounts payable and accrued expenses, variable-rate notes payable, revolving lines of credit and commercial paper and other liabilities reflected in the condensed consolidated balance sheets at September 30, 2025 and December 31, 2024 approximate fair value. Restricted cash is comprised of funds deposited with financial institutions located throughout the United States and the Cayman Islands, primarily relating to operating cash reserve for the Company’s captive insurance subsidiary and earnest money deposits on potential acquisitions.
The fair values of the Company’s fixed-rate notes payable 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.

7. 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 the two-class, treasury stock or if-converted method, whichever is most dilutive. Potential common shares are securities (such as Series B Redeemable Preferred Units (“Series B Units”), Series D Redeemable Preferred Units (“Series D Units” and, together with the Series B Units, the “Preferred OP 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 redemption 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 (i.e. those that reduce earnings per common share) are included.
For the purposes of computing the diluted impact of the potential exchange of the Preferred OP 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 liquidation value of the Preferred OP Units by the average share price for the period presented. The average share price for the three months ended September 30, 2025 and 2024 was $ 143.62 and $ 168.78 , respectively. The average share price for the nine months ended September 30, 2025 and 2024 was $ 146.84 and $ 153.61 , respectively.

8. INVESTMENTS IN UNCONSOLIDATED REAL ESTATE ENTITIES
Investments in unconsolidated real estate entities and cash distributions in unconsolidated real estate ventures represent the Company’s interest in preferred stock of SmartStop Self Storage REIT, Inc. (“SmartStop”), Strategic Storage Trust VI, Inc. and Strategic Storage Growth Trust III, Inc. (collectively, “Strategic Storage”), affiliates of SmartStop, and the Company’s noncontrolling interest in real estate joint ventures. The Company accounts for its investments in SmartStop and Strategic Storage preferred stock, which do not have a readily determinable fair value, at the transaction price less impairment, if any. The Company accounts for its investments in joint ventures using the equity method of accounting. The Company initially records these investments at cost and subsequently adjusts for cash contributions, distributions and net equity in income or loss, which is allocated in accordance with the provisions of the applicable partnership or joint venture agreement.
In these joint ventures, the Company and the joint venture partner generally receive a preferred return on their invested capital. To the extent that cash or profits in excess of these preferred returns are generated through operations or capital transactions, the Company would receive a higher percentage of the excess cash or profits, as applicable, than its equity interest.
The Company separately reports investments with net equity less than zero in cash distributions in unconsolidated real estate ventures in the condensed consolidated balance sheets. The net equity of certain joint ventures is less than zero because distributions have exceeded the Company’s investment in and share of income from these joint ventures. This is generally the

In connection with the amendment, the Company also paid off term loans within the credit facility in the amount of $ 655,000 and increased other term loans within the credit facility by $ 200,000 .
The Credit Agreement is guaranteed by the Company and is not secured by any assets of the Company. The Company’s unsecured debt is subject to certain financial covenants. As of September 30, 2025, the Company was in compliance with all of its financial covenants.
As of September 30, 2025, the Company’s percentage of fixed-rate debt to total debt was 83.8 %. The weighted average interest rates of the Company’s fixed and variable-rate debt were 4.2 % and 5.2 %, respectively. The combined weighted average interest rate was 4.4 %.
11. DERIVATIVES
The Company is exposed to certain risk 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 the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise 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 payments principally related to the Company’s 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 and nine months ended September 30, 2025 and 2024, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. In the coming 12 months, the Company estimates that $ 3,389 will be reclassified as an increase to interest income. As of

Type 2025 2024 2025 2024
Swap Agreements $ ( 2,572 ) $ 7,363 Interest expense $ 9,490 $ 22,042
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 September 30, 2025, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk related to these agreements, was immaterial. As of September 30, 2025, the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of September 30, 2025, it could have been required to cash settle its obligations under these agreements at their termination value.

12. STOCKHOLDERS’ EQUITY
On April 15, 2024, the Company filed its $ 800,000 “at the market” equity program with the Securities and Exchange Commission using a shelf registration statement on Form S-3, and entered into an equity distribution agreement with nine sales agents. No shares have been sold under the current “at the market” equity program, and no shares were sold under the previous “at the market” equity program, which spanned from August 9, 2021 through April 14, 2024.
On November 13, 2023, the Company’s board of directors authorized a share repurchase program allowing for the repurchase of shares with an aggregate value up to $ 500,000 .

During the nine months ended September 30, 2025, the Company repurchased 68,585 shares at an average price of $ 125.62 per share, paying a total of $ 8,615 . As of September 30, 2025, the Company had remaining authorization to repurchase shares with an aggregate value up to $ 491,385 .
13. 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, or (2) its redemption value as of the end of the period in which the determination is made.
At September 30, 2025 and December 31, 2024, the noncontrolling interests represented by the Preferred OP Units qualified for classification as permanent equity on the Company’s condensed consolidated balance sheets. The partnership agreement of the Operating Partnership (as amended, the “Partnership Agreement”) provides for the designation and issuance of the OP Units. The balances for each of the specific Preferred OP Units as presented in the Statements of Noncontrolling Interests and Equity as of the periods indicated are as follows:

September 30, 2025 December 31, 2024
Series B Units $ 33,567 $ 33,567
Series D Units 20,260 42,525
$ 53,827 $ 76,092

Series A Participating Redeemable Preferred Units
The Partnership Agreement provides for the designation and issuance of the Series A Units. The Series A Units have priority over all other partnership interests of the Operating Partnership with respect to distributions and liquidation. As of September 30, 2025 and December 31, 2024, there were no outstanding Series A Units.

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 Series D Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation.
The Series B Units were issued in 2013 and 2014. The Series B Units have a liquidation value of $ 25.00 per unit for a fixed liquidation value of $ 33,567 which represents 1,342,727 Series B Units outstanding at September 30, 2025. Holders of the Series B Units receive distributions at an annual rate of 6.0 %. These distributions are cumulative. The Series B Units became 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 Redeemable Preferred Units
The Partnership Agreement provides for the designation and issuance of the Series C Units. The Series C Units ranked junior to the Series A Units, on parity with the Series B Units and Series D Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation. As of September 30, 2025 and December 31, 2024, there were no outstanding Series C Units.
Series D Redeemable Preferred Units
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.

Holders of the Series D Units receive distributions at an annual rate between 3.0 % and 5.0 %. These distributions are cumulative. The Series D Units 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. In addition, certain of the Series D Units are exchangeable for OP Units at the option of the holder until the tenth anniversary of the date of issuance, with the number of OP Units to be issued equal to $ 25.00 per Series D Unit, divided by the value of a share of common stock as of the exchange date.
During the nine months ended September 30, 2025, 890,594 Series D Units were redeemed for 143,830 shares of common stock.

Between its general partner and limited partner interests, the Company held a 95.6 % ownership interest in the Operating Partnership as of September 30, 2025. The remaining ownership interests in the Operating Partnership (including Preferred OP Units) of 4.4 % are held by certain former owners of assets acquired by the Operating Partnership. As of September 30, 2025 and December 31, 2024, the noncontrolling interest in the Operating Partnership is shown on the balance sheet net of a note receivable of $ 50,000 because a borrower under the note receivable is also a holder of OP Units. This note receivable originated in December 2024, bears interest at 10 % per annum and matures on December 30, 2025.
The noncontrolling interest in the Operating Partnership represents OP Units that are not owned by the Company. OP Units are redeemable at the option of the holder, which redemption may be satisfied at the Company’s option in 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, or shares of the Company’s common stock on a one -for-one basis, subject to anti-dilution adjustments provided in the Partnership Agreement. As of September 30, 2025, the ten-day average closing price of the Company’s common stock was $ 139.99 and there were 9,339,849 OP Units outstanding. Assuming that all of the OP Unit

holders exercised their right to redeem all of their OP Units on September 30, 2025 and the Company elected to pay the OP Unit holders cash, the Company would have paid $ 1,307,485 in cash consideration to redeem the units.
OP Unit activity is summarized as follows for the periods presented:
For the Nine Months Ended September 30,
2025 2024
OP Units redeemed for common stock 41,978 308,024
OP Units redeemed for cash 10,000
Cash paid for OP Units redeemed $ 1,453 $
OP Units issued in conjunction with acquisitions 37,886
Value of OP Units issued in conjunction with acquisitions $ 5,878 $
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, or (2) its redemption value as of the end of the period in which the determination is made.
Other Noncontrolling Interests
Other noncontrolling interests represent the ownership interest of partners in 12 consolidated joint ventures as of September 30, 2025. There are a total of 16 stores in these consolidated joint ventures, 11 of which are operating and five of which are under development. The voting interests of the partners are 25.0 % or less.
Based on the facts and circumstances of each of the Company’s joint ventures, the Company has determined that one of the joint ventures at September 30, 2025 was a variable interest entity (“VIE”) in accordance with ASC 810, “Consolidation.” The Company has consolidated that joint venture as it was determined that the Company has the power to direct the activities of the joint venture and is the primary beneficiary of the joint venture.
15. SEGMENT INFORMATION
The Company’s segment disclosures present the measure used by the chief operating decision maker (“CODM”) for purposes of assessing each segment’s performance. The Company’s CODM is its Executive Committee (“EC”), which uses net operating income (“NOI”) to assess the performance of the business for the Company’s reportable operating segments. The EC is comprised of the Chief Executive Officer, Chief Financial Officer, Chief Investment Officer, Chief Digital Officer, Chief Strategy and Partnership Officer, Chief Operations Officer, and Chief Legal Officer. The Company’s segments are comprised of two reportable segments: (1) self-storage operations and (2) tenant reinsurance. NOI for the Company’s self-storage operations represents total property revenue less direct property operating expenses. NOI for the Company’s tenant reinsurance segment represents tenant reinsurance revenue less tenant reinsurance expenses.
The Company’s consolidated revenues equal total segment revenues plus management fees and other income. The self-storage operations activities include rental operations of stores that are wholly-owned and in consolidated joint ventures. Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in the stores operated by the Company. Management fees and other income is excluded from segment revenues and net operating income.
The CODM regularly reviews NOI to assess the performance of each segment and makes decisions about resources to be allocated to each segment. As part of this process, the CODM approves each operating segment’s budget, determines allocation of funds for capital expenditures, and reviews discrete financial information on a quarterly basis. Based on each segment’s budgeted operating revenues and expenses, resources are allocated to each segment, and these budgeted amounts comprising NOI are compared against actual segment performance.
For all periods presented, substantially all of the Company’s real estate assets, intangible assets, other assets, and accrued and other liabilities are associated with the self-storage operations segment. Financial information for the Company’s business segments is set forth below:

16. COMMITMENTS AND CONTINGENCIES
As of September 30, 2025, the Company was under agreement to acquire 25 stores at a total purchase price of $ 261,778 . Acquisitions of all 25 stores are scheduled to close in 2025.
As of September 30, 2025, the Company was under agreement to originate $ 27,500 in bridge loans in 2025 and $ 52,200 in 2026 and thereafter.
As of September 30, 2025, the Company was involved in various legal proceedings and was subject to various claims and complaints arising in the ordinary course of business. Because litigation is inherently unpredictable, the outcome of these matters cannot presently be determined with any degree of certainty. In accordance with applicable accounting guidance, management establishes an accrued liability for litigation when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. The estimated loss, if any, is based upon currently available information and is subject to significant judgment, a variety of assumptions, and known and unknown uncertainties. The Company could incur judgments or enter into settlements of claims in the future that could have a material adverse effect on its results of operations in any particular period, notwithstanding the fact that the Company is currently vigorously defending any legal proceedings against it.
Although there can be no assurance, the Company is not aware of any material environmental liability, for which it believes it will be ultimately responsible, that could have a material adverse effect on its financial condition or results of operations. However, changes in applicable environmental laws and regulations, the uses and conditions of properties in the vicinity of the Company’s properties, the activities of its tenants and other environmental conditions of which the Company is unaware with respect to its properties could result in future material environmental liabilities.
17. SUBSEQUENT EVENTS
On October 29, 2025, the Company closed on the acquisition of 13 properties located in Arizona, Nevada and Utah. The Company acquired 11 of the properties on a wholly-owned basis for $ 118,250 , with the remaining two properties entering joint ventures where the Company’s investment totaled $ 2,455 .

ITEM 2.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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, 2024. 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 U.S. generally accepted accounting principles (“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, 2024 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 real estate investment trust (“REIT”), formed to own, operate, manage, acquire, develop and redevelop self-storage properties (“stores”). We derive substantially all of our revenues from our two segments: self-storage operations and tenant reinsurance. Primary sources of revenue for our self-storage operations segment include rents received from tenants under leases at stores that are wholly-owned and in consolidated joint ventures. Our operating results depend materially on our ability to lease available self-storage units, to actively manage unit rental rates, and on the ability of our tenants to make required rental payments. Consequently, management spends a significant portion of their time maximizing cash flows from our diverse portfolio of stores. Revenue from our tenant reinsurance segment consists of insurance revenues from the reinsurance of risks relating to the loss of goods stored by tenants in our stores.
Our stores are generally situated in highly visible locations clustered around large population centers. The clustering of our assets around these population centers enables us to reduce our operating costs through economies of scale. To maximize the performance of our stores, we employ industry-leading revenue management systems. Developed by our management team, these systems enable us to analyze, set and adjust rental rates daily across our portfolio in order to respond to changing market conditions. We believe our systems and processes allow us to more proactively manage revenues.
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. We believe that we are able to respond quickly and effectively to changes in local, regional and national economic conditions by adjusting rental rates through the combination of our revenue management team and our industry-leading technology systems. 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 been open for three years or has sustained average square foot occupancy of 80% or more for one calendar year.

PROPERTIES
As of September 30, 2025, we owned or had ownership interests in 2,427 operating stores. Of these stores, 2,005 are wholly-owned, 11 are in consolidated joint ventures, and 411 are in unconsolidated joint ventures. In addition, we managed an additional 1,811 stores for third parties bringing the total number of stores which we own and/or manage to 4,238. These stores are located in 43 states and Washington, D.C. The majority of our stores are clustered around large population centers. The clustering of assets around these population centers enables us to reduce our operating costs through economies of scale. Our acquisitions have given us an increased scale in many core markets as well as a foothold in many markets where we had no previous presence.
As of September 30, 2025, approximately 2,460,000 tenants were leasing storage units at the 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 same-stores as of September 30, 2025, the average length of stay for tenants who have vacated was approximately 17.0 months.
Our store portfolio is made up of different types of construction and building configurations. Most often sites are what we consider “hybrid” stores, a mix of drive-up and multi-floor buildings.

RESULTS OF OPERATIONS

Amounts in thousands, except store and share data

Comparison of the three and nine months ended September 30, 2025 and 2024

Overview
Results for the three and nine months ended September 30, 2025 included the operations of 2,427 stores (2,005 wholly-owned, 11 in consolidated joint ventures, and 411 in joint ventures accounted for using the equity method) compared to the results for the three and nine months ended September 30, 2024, which included the operations of 2,401 stores (1,934 wholly-owned, seven in consolidated joint ventures, and 460 in joint ventures accounted for using the equity method).

Revenues
The following table presents information on revenues earned for the periods indicated:
For the Three Months Ended September 30, For the Nine Months Ended September 30,
2025 2024 $ Change % Change 2025 2024 $ Change % Change
Revenues:
Property rental $ 735,581 $ 710,874 $ 24,707 3.5 % $ 2,160,965 $ 2,096,018 $ 64,947 3.1 %
Tenant reinsurance 90,341 84,048 6,293 7.5 % 263,625 249,100 14,525 5.8 %
Management fees and other income 32,538 29,882 2,656 8.9 % 95,485 89,888 5,597 6.2 %
Total revenues $ 858,460 $ 824,804 $ 33,656 4.1 % $ 2,520,075 $ 2,435,006 $ 85,069 3.5 %

Property rental— The increase in property rental revenues for the three and nine months ended September 30, 2025 was primarily the result of an increase of $32,063 and $78,672, respectively, associated with acquisitions completed in 2024 and acquisitions completed in the first nine months of 2025. The increase in revenue resulting from these acquisitions was partially offset by decreases in rental revenue of $5,882 and $15,601, respectively, due to property dispositions for the three and nine months ended September 30, 2025. We acquired 58 wholly-owned stores and disposed of six wholly-owned stores in 2024, and we acquired 46 wholly-owned stores and disposed of 12 wholly-owned stores during the nine months ended September 30, 2025.
Tenant reinsurance— The increase in tenant reinsurance revenues was due primarily to an increase in the number of stores operated. We operated 4,238 stores at September 30, 2025 compared to 3,862 stores at September 30, 2024.
Management fees and other income— Management fees and other income primarily represent the fees collected for our management of stores owned by third parties and unconsolidated joint ventures and other transaction fee income. The increase for the three and nine months ended September 30, 2025 was due to both an increase in the number of stores managed and an increase in the overall revenue of stores under management when compared to the same period last year. As of September 30, 2025, we managed 2,222 stores for unconsolidated joint ventures and third parties, compared to 1,921 stores as of September 30, 2024.

Property operations— The increase in property operations expense during the three and nine months ended September 30, 2025 consists primarily of an increase of $14,738 and $38,855, respectively, related to acquisitions completed in 2024 and acquisitions completed in the first nine months of 2025. We acquired 58 wholly-owned stores in 2024 and an additional 46 wholly-owned stores during the nine months ended September 30, 2025. Additionally, for the three and nine months ended September 30, 2025, there was an increase of $9,184 and $31,215, respectively, at our same-store properties primarily due to an increase in payroll and benefits, marketing, repairs and maintenance, and property tax expenses.
Tenant reinsurance— Tenant reinsurance expense represents the costs that are incurred to provide tenant reinsurance and is subject to volatility due to increased claims arising when significant events occur at stores.
General and administrative— General and administrative expenses primarily include all expenses not directly related to our stores, including corporate payroll, office expense, office rent, travel and professional fees. These expenses are recognized as incurred. Our overall general and administrative expense increased primarily as a result of our increased size through acquisitions and growth in our managed portfolio.
Depreciation and amortization— We amortize to expense intangible assets-customer intangibles on a straight-line basis over the average period that a tenant is expected to utilize the facility (currently estimated at 18 months). Depreciation and amortization expense decreased for both the three and nine month periods, primarily due to the customer intangibles associated with our merger with Life Storage being fully expensed in January of this year.

Other Revenues and Expenses
The following table presents information on other revenues and expenses for the periods indicated:
For the Three Months Ended September 30, For the Nine Months Ended September 30,

Total other revenues & expenses, net $ (210,215) $ (160,518) $ (49,697) 31.0 % $ (390,377) $ (436,280) $ 45,903 (10.5) %

Loss on real estate assets held for sale and sold, net— As of September 30, 2025, we had 29 properties classified as held for sale. Of the 29 stores, 27 had an estimated fair value, net of selling costs, less than the carrying value of the assets. During the three and nine months ended September 30, 2025, we recorded estimated net losses of $105,128 and $108,887, respectively. Additionally, we completed the sale of 12 previously held for sale stores, resulting in a net gain of $38,656, which partially offset the loss recorded for the nine months ended September 30, 2025. As of September 30, 2024, we had 17 stores classified as held for sale. Of the 17 stores, nine had an estimated fair value, net of selling costs, less than the carrying value of the assets. During the three and nine months ended September 30, 2024, we recorded estimated losses of $8,961 and $63,620, respectively.

33


Interest expense— The increase in interest expense during the three and nine months ended September 30, 2025 was primarily the result of higher outstanding debt. As of September 30, 2025, we had approximately $13,162,058 in total face value of debt, compared to approximately $11,827,208 as of September 30, 2024.
Non-cash interest expense related to amortization of discount on unsecured senior notes, net— Represents the amortization of the discount assigned to the fair value of the Life Storage unsecured senior notes assumed as part of the Life Storage Merger and net premium from bond offerings, offset by the discount from assumed debt.
Interest income— Interest income represents interest earned on variable interest rate bridge loans, debt securities and on notes receivable from Common Operating Partnership unit holders. The increase in interest income during the three and nine months ended September 30, 2025 was primarily the result of an increase in the amount of bridge loans outstanding. The balance of bridge loans was $1,544,719 as of September 30, 2025, compared to $1,032,244 as of September 30, 2024.
Equity in earnings and dividend income from unconsolidated real estate entities— Equity in earnings of unconsolidated real estate entities represents the income earned through our ownership interests in unconsolidated joint ventures. In these joint ventures, we and our joint venture partners generally receive a preferred return on our invested capital. To the extent that cash or profits in excess of these preferred returns are generated, we receive a higher percentage of the excess cash or profits. The increase for the nine months ended September 30, 2025 is primarily due to the transaction in November 2024 in which we acquired additional ownership interest in the HF1 Sovran HHF Storage Holdings LLC and HF2 Sovran HHF Storage Holdings II LLC from our partner in the unconsolidated joint ventures. The transaction increased our equity ownership percentages from 20% and 15%, respectively, to 49% in each unconsolidated joint venture. The decrease for the three months ended September 30, 2025 is primarily due to the transfer and distribution of membership interests in the PR II EXR JV LLC joint venture in March 2025, the acquisition of our partners’ membership interests in the ESS-NYFL JV LP and ESS CA-TIVS JV LP joint ventures in April 2025, and the sale of our membership interest in the Life Storage Spacemax LLC joint venture in July 2025. The number of stores in unconsolidated joint ventures in which we have ownership interests was 411 as of September 30, 2025, compared to 460 as of September 30, 2024. Dividend income represents dividends from our investment in preferred stock of SmartStop and its affiliates.
Equity in earnings of unconsolidated real estate ventures - gain on sale of real estate assets and sale of a joint venture interest —The net gain of $9,354 for the three and nine months ended September 30, 2025 is due to the sale of our membership interest in the Life Storage Spacemax LLC joint venture, which held six properties, in July 2025. During the three months ended September 30, 2024, the ESS Bristol Investments LLC joint venture sold five of its eight stores to one of our unconsolidated joint ventures, and we recognized a gain of $10,324 for our pro rata share of the transaction. Additionally, we sold our membership interest in the Alan Jathoo JV LLC unconsolidated joint venture, which held nine stores, to our partner and recognized a gain of $3,406 as a result of the transaction.

Impairment of Life Storage trade name —During the three months ended September 30, 2024, we decided to operate all our stores under a single brand. As a result of that decision, we deemed the Life Storage trade name as an intangible asset to be impaired and recognized a loss for the full value of the asset.
Income tax expense —The increase in income tax expense for the three and nine months ended September 30, 2025 was primarily the result of an increase in book income and a decrease in permanent tax deductions related to stock awards.
FUNDS FROM OPERATIONS

Funds from operations (“FFO”) provides relevant and meaningful information about our operating performance that is necessary, along with net income and cash flows, for an understanding of our operating results. We believe 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 we believe FFO more accurately reflects the value of our real estate assets. FFO is defined by the National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) as net income computed in accordance with GAAP, excluding gains or losses on sales of operating stores and impairment write-downs of depreciable real estate assets, plus real estate related depreciation and amortization and after adjustments to record unconsolidated partnerships and joint ventures on the same basis. We believe that to further understand our performance, FFO should be considered along with the reported net income and cash flows in accordance with GAAP, as presented in our condensed consolidated financial statements. FFO should not be considered a replacement of net income computed in accordance with GAAP.
The computation of FFO 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

34


considered as an alternative to net income as an indication of our performance, as an alternative to net cash flow from operating activities, as a measure of our liquidity, or as an indicator of our ability to make cash distributions.
The following table presents the calculation of FFO for the periods indicated:

SAME-STORE RESULTS
Our same-store pool for the periods presented consists of 1,829 stores that are wholly-owned and operated and that were stabilized by the first day of the earliest calendar year presented. We consider a store to be stabilized once it has been open for three years or has sustained average square foot occupancy of 80% or more for one calendar year. We believe that by providing same-store results from a stabilized pool of stores, with accompanying operating metrics including but not limited to occupancy, rental revenue growth, operating expense growth, net operating income growth, etc., stockholders and potential investors are able to evaluate operating performance without the effects of non-stabilized occupancy levels, rent levels, expense levels, acquisitions or completed developments. Same-store results should not be used as a basis for future same-store performance or for the performance of our stores as a whole.

CASH FLOWS

Cash flows from operating activities for the nine months ended September 30, 2025 increased when compared to the same period in the prior year. Cash flows used in investing activities relate primarily to our acquisition and development of new stores, sales of stores, investments in unconsolidated real estate entities, and notes receivable from bridge loans and fluctuate depending on our actions in those areas. Cash flows from financing activities depend primarily on our debt and equity financing activities. A summary of cash flows along with significant components are as follows:
For the Nine Months Ended September 30,
2025 2024
Net cash provided by operating activities $ 1,482,396 $ 1,479,151
Net cash used in investing activities (697,662) (877,503)
Net cash used in financing activities (811,803) (612,406)
Significant components of net cash flow included:
Net income $ 721,674 $ 622,431
Depreciation and amortization 535,088 586,821
Acquisition and development of real estate assets (698,614) (461,633)
Proceeds from sale of real estate assets 168,747 4,415
Investment in unconsolidated real estate entities (107,178) (7,175)
Return of investment in unconsolidated real estate ventures 231,130 12,999
Issuance of notes receivable, net of sales and principal payments (276,043) (410,396)
Net proceeds (payments) from unsecured term loans, senior notes, revolving lines of credit and commercial paper (1,344,259) (520,534)
Proceeds from issuance of public bonds, net 1,650,000 1,000,000
Dividends paid on common stock (1,031,930) (1,031,044)
We believe that cash flows generated by operations, along with our existing cash and cash equivalents, the availability of funds under our existing lines of credit, and our access to capital markets will be sufficient to meet all of our reasonably anticipated cash needs during the next twelve months. These cash needs include operating expenses, monthly debt service payments, acquisitions, funding for the bridge loan program, recurring capital expenditures, building redevelopments and expansions, distributions to unit holders and dividends to stockholders necessary to maintain our REIT qualification.
We expect to generate positive cash flow from operations in 2025, and we consider projected cash flows in our sources and uses of cash. These cash flows are principally derived from rents paid by our tenants. A significant deterioration in projected cash flows from operations could cause us to increase our reliance on available funds under our existing lines of credit, curtail planned capital expenditures, or seek other additional sources of financing.

LIQUIDITY AND CAPITAL RESOURCES
As of September 30, 2025, we had $111,931 available in cash and cash equivalents. Our cash and cash equivalents are held in accounts managed by third party financial institutions and consist of invested cash and cash in our operating accounts. During 2025 and 2024, we experienced no loss or lack of access to our cash and cash equivalents; however, there can be no assurance that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial markets.
The following table presents information relating to our debt:
September 30, 2025
Total face value of debt $ 13,162,058
Total enterprise value ratio 29.6 %
Total fixed-rate debt and other instruments to total debt
83.8% (1)
Weighted average interest rate of total debt 4.4 %
(1) $11,025,665 total fixed-rate debt including $952,000 on which we have interest rate swaps that have been included as fixed-rate debt.

38


We expect to fund our short-term liquidity requirements, including operating expenses, recurring capital expenditures, dividends to stockholders, distributions to holders of Operating Partnership units and interest on our outstanding indebtedness, out of our operating cash flow, cash on hand and borrowings under our revolving lines of credit and commercial paper. In addition, we are pursuing additional sources of financing based on anticipated funding needs and growth assumptions.
In November 2024, we established our commercial paper program, under which we may issue, repay and re-issue short-term unsecured commercial paper notes. The aggregate principal amount outstanding under the program at any time cannot exceed $1,000,000, and the net proceeds of the commercial paper notes are expected to be used for general corporate purposes. The maturities of the notes generally range from overnight to three months, with a maximum of up to 13 months. The commercial paper notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. At any point in time, we expect to maintain available commitments under our Credit Facilities in an amount at least equal to the amount of commercial paper notes outstanding. At September 30, 2025, we had $540,000 in issuances outstanding under the commercial paper program.
We hold a BBB+/Stable rating from S&P, which was upgraded from BBB/Stable in July 2023 in connection with the Life Storage Merger, and a Baa2/Positive rating from Moody’s Investors Service. We intend to manage our balance sheet to maintain these ratings. Certain of our real estate assets are pledged as collateral for our debt. As of September 30, 2025, we had a total of 1,786 unencumbered stores as defined by our public bonds. Our unencumbered asset value was calculated as $30,315,349 and our total asset value was calculated as $35,717,864 according to the calculations as defined by our public bonds. We are subject to certain restrictive covenants relating to our outstanding debt. We were in compliance with all financial covenants at September 30, 2025.
Our liquidity needs consist primarily of operating expenses, monthly debt service payments, recurring capital expenditures, dividends to stockholders and distributions to unit holders necessary to maintain our REIT qualification. We may from time to time seek to repurchase our outstanding debt, shares of common stock or other securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. In addition, we evaluate, on an ongoing basis, the merits of strategic acquisitions and other relationships, which may require us to raise additional funds. We may also use Operating Partnership units as currency to fund acquisitions from self-storage owners.
On April 15, 2024, we entered into an equity distribution agreement (the “Equity Distribution Agreement”) with certain sales agents and forward purchasers named therein. Under the terms of the Equity Distribution Agreement, we may issue and sell, and the forward purchasers may sell, from time to time through or to the sales agents, shares of our common stock having an aggregate offering price of up to $800,000. The shares of common stock will be offered pursuant to our effective registration statement on Form S-3 (Registration Statement No. 333-278690) previously filed with and declared effective by the Securities and Exchange Commission (the “SEC”) and a prospectus supplement and accompanying prospectus, filed with the SEC. As of September 30, 2025, no shares have been sold under the Equity Distribution Agreement, which we refer to as our “at the market” equity program.

OFF-BALANCE SHEET ARRANGEMENTS
Except as disclosed in the notes to our consolidated financial statements of our most recently filed Annual Report on Form 10-K, we do not currently have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purposes entities, which typically are established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, except as disclosed in the notes to our condensed consolidated financial statements, we have not guaranteed any obligations of unconsolidated entities, nor do we have any commitments or intent to provide funding to any such entities. Accordingly, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

SEASONALITY
The self-storage business is subject to seasonal fluctuations. A greater portion of revenues and profits is typically realized from May through September. Historically, our highest level of occupancy has been at the end of July, while our lowest level of occupancy has been in late February and early March. Results for any quarter may not be indicative of the results that may be achieved for the full fiscal year.

RECENT TAX LEGISLATION
On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted into law, which included certain modifications to U.S. tax law, including certain provisions that affect the taxation of REITs and their investors. The OBBBA permanently extended certain provisions that were enacted in the Tax Cuts and Jobs Act of 2017. Such extensions included the

39


permanent extension of the 20% deduction for “qualified REIT dividends” for individuals and other non-corporate taxpayers. The OBBBA also increased the percentage limit under the REIT asset test applicable to taxable REIT subsidiaries (the permissible value of taxable REIT subsidiary securities that a REIT may hold) from 20% to 25% of the value of the REIT’s total assets for taxable years beginning after December 31, 2025. We are currently evaluating the provisions of the OBBBA, but we do not expect the OBBBA to have a material impact on our financial position and/or results of operations.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk
Market risk refers to the risk of loss from adverse changes in market prices and interest rates. Our future income, cash flows and fair values of financial instruments are dependent upon prevailing market interest rates.
Interest Rate Risk
Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control.
As of September 30, 2025, we had approximately $13.2 billion in total face value of debt, of which approximately $2.1 billion was subject to variable interest rates (excluding debt with interest rate swaps). If SOFR was to increase or decrease by 100 basis points, the increase or decrease in interest expense on the variable-rate debt would increase or decrease future earnings and cash flows by approximately $21.4 million annually.
Interest rate risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

ITEM 4.    CONTROLS AND PROCEDURES

(1) Disclosure Controls and Procedures
We maintain disclosure controls and procedures to ensure that information required to be disclosed in the reports we file pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide a reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
We have a disclosure committee that is responsible for considering the materiality of information and determining the disclosure obligations of the Company on a timely basis. The disclosure committee meets quarterly and reports directly to our Chief Executive Officer and Chief Financial Officer.
We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this report.

(2) Changes in internal control over financial reporting
There were no changes in our internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) that occurred during our most recent quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.     OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS
We are involved in various legal proceedings and are subject to various claims and complaints arising in the ordinary course of business. Because litigation is inherently unpredictable, the outcome of these matters cannot presently be determined with any degree of certainty. In accordance with applicable accounting guidance, management establishes an accrued liability for litigation when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. The estimated loss, if any, is based upon currently available information and is subject to significant judgment, a variety of assumptions, and known and unknown uncertainties. We could in the future incur judgments or enter into settlements of claims that could have a material adverse effect on our results of operations in any particular period, notwithstanding the fact that we are currently vigorously defending any legal proceedings against us.

ITEM 1A.    RISK FACTORS
In addition to the other information set forth in this report, you should carefully consider the factors discussed in “Part I. Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, which could materially affect our business, financial condition and results of operations. There have been no material changes to the risk factors described in the “Risk Factors” section in our Annual Report on Form 10-K for the year ended December 31, 2024. The risks described in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect our business, financial condition and results of operations.

ITEM 2.    UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

None.

ITEM 3.    DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4.    MINE SAFETY DISCLOSURES

Not Applicable.

ITEM 5.    OTHER INFORMATION
During the three months ended September 30, 2025, none of our officers or directors adopted , modified or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non Rule 10b5-1 trading arrangement.”
