EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2026 of CubeSmart (the “Parent Company” or “CubeSmart”) and CubeSmart, L.P. (the “Operating Partnership”). The Parent Company is a Maryland real estate investment trust (“REIT”) that owns its assets and conducts its operations through the Operating Partnership, a Delaware limited partnership, and subsidiaries of the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company”. In addition, terms such as “we”, “us” or “our” used in this report may refer to the Company, the Parent Company and/or the Operating Partnership.

The Parent Company is the sole general partner of the Operating Partnership and, as of June 30, 2026, owned a 99.6% interest in the Operating Partnership. The remaining 0.4% interest consists of common units of limited partnership interest issued by the Operating Partnership to third parties in exchange for contributions of properties to the Operating Partnership. As the sole general partner of the Operating Partnership, the Parent Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.

Management operates the Parent Company and the Operating Partnership as one enterprise. The management teams of the Parent Company and the Operating Partnership are identical, and their constituents are officers of both the Parent Company and of the Operating Partnership.

There are a few differences between the Parent Company and the Operating Partnership, which are reflected in the note disclosures in this report. The Company believes it is important to understand the differences between the Parent Company and the Operating Partnership in the context of how these entities operate as a consolidated enterprise. The Parent Company is a REIT, whose only material asset is its ownership of the partnership interests of the Operating Partnership. As a result, the Parent Company does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing the debt obligations of the Operating Partnership. The Operating Partnership holds substantially all of the assets of the Company and, directly or indirectly, holds the ownership interests in the Company’s real estate ventures. The Operating Partnership conducts the operations of the Company’s business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Parent Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s direct or indirect incurrence of indebtedness or through the issuance of partnership units of the Operating Partnership or equity interests in subsidiaries of the Operating Partnership.

The substantive difference between the Parent Company’s and the Operating Partnership’s filings is the fact that the Parent Company is a REIT with public equity, while the Operating Partnership is a partnership with no publicly traded equity. In the consolidated financial statements, this difference is primarily reflected in the equity (or capital for the Operating Partnership) section of the consolidated balance sheets and in the consolidated statements of equity (or capital). Apart from the different equity treatment, the unaudited consolidated financial statements of the Parent Company and the Operating Partnership are nearly identical.

The Company believes that combining the quarterly reports on Form 10-Q of the Parent Company and the Operating Partnership into a single report will:

facilitate a better understanding by the investors of the Parent Company and the Operating Partnership by enabling them to view the business as a whole in the same manner as management views and operates the business;
remove duplicative disclosures and provide a more straightforward presentation in light of the fact that a substantial portion of the disclosure applies to both the Parent Company and the Operating Partnership; and
create time and cost efficiencies through the preparation of one combined report instead of two separate reports.

Table of Contents

In order to highlight the differences between the Parent Company and the Operating Partnership, the separate sections in this report for the Parent Company and the Operating Partnership specifically refer to the Parent Company and the Operating Partnership. In the sections that combine disclosures of the Parent Company and the Operating Partnership, this report refers to such disclosures as those of the Company. Although the Operating Partnership is generally the entity that directly or indirectly enters into contracts and real estate ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Parent Company operates the business through the Operating Partnership.

As general partner with control of the Operating Partnership, the Parent Company consolidates the Operating Partnership for financial reporting purposes, and the Parent Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the Parent Company and the Operating Partnership are the same on their respective consolidated financial statements. The separate discussions of the Parent Company and the Operating Partnership in this report should be read in conjunction with each other to understand the results of the Company’s operations on a consolidated basis and how management operates the Company.

This report also includes separate Item 4 - Controls and Procedures sections, signature pages and Exhibits 31 and 32 certifications for each of the Parent Company and the Operating Partnership, in order to establish that the Chief Executive Officer and the Chief Financial Officer of the Parent Company and the Chief Executive Officer and the Chief Financial Officer of the Operating Partnership have made the requisite certifications and that the Parent Company and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended, and 18 U.S.C. §1350.

Forward-Looking Statements

This Quarterly Report on Form 10-Q, or “this Report”, together with other statements and information publicly disseminated by the Parent Company and the Operating Partnership, contain certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, or the “Exchange Act.” Forward-looking statements include statements concerning the Company’s plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as “believes,” “expects,” “estimates,” “may,” “will,” “should,” “anticipates,” or “intends” or the negative of such terms or other comparable terminology, or by discussions of strategy. Such statements are based on assumptions and expectations that may not be realized and are inherently subject to risks, uncertainties and other factors, many of which cannot be predicted with accuracy and some of which might not even be anticipated. Although we believe the expectations reflected in these forward-looking statements are based on reasonable assumptions, future events and actual results, performance, transactions or achievements, financial and otherwise, may differ materially from the results, performance, transactions or achievements expressed or implied by the forward-looking statements. As a result, you should not rely on or construe any forward-looking statements in this Report, or which management or persons acting on their behalf may make orally or in writing from time to time, as predictions of future events or as guarantees of future performance. We caution you not to place undue reliance on forward-looking statements, which speak only as of the date of this Report or as of the dates otherwise indicated in such forward-looking statements. All of our forward-looking statements, including those in this Report, are qualified in their entirety by this statement.

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 and uncertainties referred to in Item 1A. “Risk Factors” in the Parent Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2025 and in our other filings with the Securities and Exchange Commission (“SEC”). These risks include, but are not limited to, the following:

adverse changes in economic conditions in the real estate industry and in the markets in which we own and operate self-storage properties;

the effect of competition from existing and new self-storage properties and operators on our ability to maintain or raise occupancy and rental rates;

the failure to execute our business plan;

adverse consumer impacts and declines in general economic conditions from inflation, tariffs, changes in interest rates and wage stagnation, including impacts on the demand for self-storage, rental rates and fees and rent collection levels;

reduced availability and increased costs of external sources of capital;

financing risks, including rising interest rates, the risk of over-leverage and the corresponding risk of default on our mortgage and other debt and potential inability to refinance existing or future debt;

counterparty non-performance related to the use of derivative financial instruments;

risks related to our ability to maintain our Parent Company’s qualification as a REIT for federal income tax purposes;

the failure of acquisitions or developments of self-storage properties to close on expected terms, or at all, or to perform as expected;

increases in taxes, fees and assessments from state and local jurisdictions;

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

reductions in asset valuations and related impairment charges;

negative publicity relating to our business or industry, which could adversely affect our reputation;

5

Table of Contents

increases in operating costs, including, without limitation, insurance, utility and other general expenses, which could adversely affect our financial results;

cybersecurity breaches, cyber or ransomware attacks or a failure of our networks, systems or technology, which could adversely impact our business, customer and employee relationships or result in fraudulent payments;

risks associated with generative artificial intelligence tools and large language models and the conclusions that these tools and models may draw about our business and prospects in connection with the dissemination of negative opinions, characterizations or disinformation;

changes in real estate, zoning, use and occupancy laws or regulations;

risks related to or consequences of earthquakes, hurricanes, windstorms, floods, wildfires, other natural disasters or acts of violence, pandemics, active shooters, terrorism, insurrection or war that impact the markets in which we operate;

potential environmental and other material liabilities;

governmental, administrative and executive orders, regulations and laws, which could adversely impact our business operations and customer and employee relationships;

uninsured or uninsurable losses and the ability to obtain insurance coverage, indemnity or recovery from insurance against risks and losses;

changes in the availability of and the cost of labor;

other factors affecting the real estate industry generally or the self-storage industry in particular; and

other risks identified in the Parent Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2025 and, from time to time, in other reports that we file with the SEC or in other documents that we publicly disseminate.

Given these uncertainties and the other risks identified elsewhere in this Report, we caution readers not to place undue reliance on forward-looking statements. We undertake no obligation to publicly update or revise these forward-looking statements, whether as a result of new information, future events or otherwise except as may be required by securities laws. Because of the factors referred to above, the future events discussed in or incorporated by reference in this Report may not occur and actual results, performance or achievement could differ materially from that anticipated or implied in the forward-looking statements.

CUBESMART AND CUBESMART, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND NATURE OF OPERATIONS

CubeSmart (the “Parent Company”) operates as a self-managed and self-administered real estate investment trust (“REIT”) with its operations conducted solely through CubeSmart, L.P. and its subsidiaries. CubeSmart, L.P., a Delaware limited partnership (the “Operating Partnership”), operates through an umbrella partnership structure, with the Parent Company, a Maryland REIT, as its sole general partner. In the notes to the unaudited consolidated financial statements, we use the terms the “Company”, “we” or “our” to refer to the Parent Company and the Operating Partnership together, unless the context indicates otherwise. As of June 30, 2026, the Company owned (or partially owned and consolidated) self-storage properties located in the District of Columbia and 25 states throughout the United States, which are presented under one reportable segment: the Company owns, operates, develops, manages and acquires self-storage properties (see note 14).

As of June 30, 2026, the Parent Company owned approximately 99.6% of the partnership interests (“OP Units” or “common units”) of the Operating Partnership. The remaining OP Units, consisting exclusively of limited partner interests, are held by persons who contributed their interests in properties to the Operating Partnership in exchange for OP Units. Under the partnership agreement, these persons have the right to tender their OP Units for redemption to the Operating Partnership at any time following a specified restricted period for cash equal to the fair value of an equivalent number of common shares of the Parent Company. In lieu of delivering cash, however, the Parent Company, as the Operating Partnership’s general partner, may, at its option, choose to acquire any OP Units so tendered by issuing common shares in exchange for the tendered OP Units. If the Parent Company so chooses, its common shares will be exchanged for OP Units on a one-for-one basis. This one-for-one exchange ratio is subject to adjustment to prevent dilution. With each such exchange or redemption, the Parent Company’s percentage ownership in the Operating Partnership will increase. In addition, whenever the Parent Company issues common or other classes of its shares, it contributes the net proceeds it receives from the issuance to the Operating Partnership and the Operating Partnership issues to the Parent Company an equal number of OP Units or other partnership interests having preferences and rights that mirror the preferences and rights of the shares issued. This structure is commonly referred to as an umbrella partnership REIT or “UPREIT.”

The Company typically experiences seasonal fluctuations in the occupancy levels of its stores, which are generally slightly higher during the summer months due to increased moving activity.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting and, in the opinion of each of the Parent Company’s and Operating Partnership’s respective management, include all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of financial position, results of operations and cash flows for each respective company for the interim periods presented in accordance with generally accepted accounting principles in the United States (“GAAP”). Accordingly, readers of this Quarterly Report on Form 10-Q should refer to the Parent Company’s and the Operating Partnership’s combined audited financial statements prepared in accordance with GAAP, and the related notes thereto, for the year ended December 31, 2025, which are included in the Parent Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The results of operations for the three and six months ended June 30, 2026 and 2025 are not necessarily indicative of the results of operations to be expected for any future period or the full year.

The Operating Partnership meets the criteria of a variable interest entity (“VIE”). The Parent Company’s sole significant asset is its investment in the Operating Partnership. As a result, substantially all of the Parent Company’s assets and liabilities represent those assets and liabilities of the Operating Partnership. All of the Parent Company’s debt

is an obligation of the Operating Partnership, and the Parent Company guarantees the unsecured debt obligations of the Operating Partnership.

Recent Accounting Pronouncements

2025 Acquisitions

On February 20, 2025, the Company acquired the remaining 80% ownership interest in HVP IV, an unconsolidated real estate venture in which, prior to such acquisition, the Company owned a 20% noncontrolling interest that was accounted for under the equity method of accounting. As of the date of acquisition, HVP IV owned 28 stores located in Arizona (2), Connecticut (3), Florida (4), Georgia (2), Illinois (5), Maryland (2), Minnesota (1), Pennsylvania (1) and Texas (8) (the “HVP IV Assets”). The purchase price for the 80% ownership interest was $452.8 million, which included $44.4 million to repay the Company’s portion of the venture’s existing indebtedness. The HVP IV Assets were recorded by the Company at $466.9 million, which consisted of the $452.8 million purchase price plus the Company's $14.1 million carryover basis of its previously held equity interest in HVP IV. As a result of the transaction, the HVP IV Assets became wholly owned by the Company and are now consolidated within its financial statements. No gain or loss was recognized as a result of the transaction. In connection with the transaction, which was accounted for as an asset acquisition, the Company allocated the value of the HVP IV Assets and acquisition-related costs to the tangible and intangible assets acquired based on relative fair value. Intangible assets consisted of in-place leases, which aggregated to $32.0 million at the time of the acquisition and prior to amortization of such amounts. The estimated life of these in-place leases was 12 months and the amortization expense that was recognized during the six months ended June 30, 2026 was approximately $5.3 million. There was no amortization expense recognized for these in-place leases during the three months ended June 30, 2026. The amortization expense that was recognized during the three and six months ended June 30, 2025 was approximately $8.0 million and $10.7 million, respectively.

During the year ended December 31, 2025, the Company also acquired one store in Arizona and one store in Florida for an aggregate purchase price of $49.0 million. In connection with these transactions, which were accounted for as asset acquisitions, the Company allocated the purchase price and acquisition-related costs to the tangible and intangible assets acquired based on relative fair value. Intangible assets consisted of in-place leases, which aggregated to $2.7 million at the time of the acquisition and prior to amortization of such amounts. The estimated life of these in-place leases is 12 months and the amortization expense that was recognized during the three and six months ended June 30, 2026 was approximately $0.7 million and $1.3 million, respectively. There was no amortization expense recognized for these in-place leases during the three or six months ended June 30, 2025.

Development Activity

As of June 30, 2026, the Company held an ownership interest in a consolidated joint venture to develop a single self-storage property located in New York. Construction for this project is expected to be completed during the third quarter of 2027. As of June 30, 2026, development costs incurred to date for this project totaled $11.5 million. Total costs for this project are expected to be $28.0 million. These costs are capitalized to construction in progress while the project is under development and are reflected in Storage properties on the Company’s consolidated balance sheets.

The Company, through two consolidated joint ventures, completed the construction and opened for operation the following stores during the period from January 1, 2025 through June 30, 2026. The costs associated with the construction of these stores are capitalized to land, building and improvements, as well as equipment and are reflected in Storage properties on the Company’s consolidated balance sheets.

(1)On December 9, 2021, the Company completed the acquisition of LAACO, which included a 50% interest in Fontana and RCSS, each of which owns one self-storage property in California. As of the date of acquisition, the Company recognized differences between the Company’s equity investment in Fontana and RCSS and the underlying equity reflected at the venture level. These differences are being amortized over the expected useful life of the self-storage properties owned by the ventures. As of June 30, 2026, the remaining unamortized difference was $11.9 million for Fontana and $17.8 million for RCSS.

On February 20, 2025, the Company purchased the remaining 80% interest in HVP IV for $452.8 million and consolidated the venture’s assets and liabilities. The $452.8 million purchase price included $44.4 million to repay the Company’s portion of the venture’s existing indebtedness, which was repaid in full at the time of the transaction (see note 4).

The Company determined that CBPR, Fontana, RCSS, HVP V, HVP IV, HHFNE and HHF (collectively, the “Ventures”) are not VIEs in accordance with the accounting standard for the consolidation of VIEs. As a result, the Company used the voting interest model under the accounting standard for consolidation in order to determine whether to consolidate the Ventures. Based upon each member’s substantive participating rights over the activities of each entity as stipulated in the operating agreements, the Ventures are not consolidated by the Company and are accounted for under the equity method of accounting (except for HVP IV, which was consolidated upon the Company’s purchase of the remaining 80% interest on February 20, 2025). The Company’s investments in the Ventures are included in Investment in real estate ventures, at equity on the Company’s consolidated balance sheets and the Company’s earnings from its investments in the Ventures are presented in Equity in earnings of real estate ventures within the Company’s consolidated statements of operations.

The amounts reflected in the following table are based on the historical financial information of the Ventures. The following is a summary of the financial position of the Ventures as of June 30, 2026 and December 31, 2025.

The indenture under which the Senior Notes were issued restricts the ability of the Operating Partnership and its subsidiaries to incur debt unless the Operating Partnership and its consolidated subsidiaries comply with a leverage ratio not to exceed 60% and an interest coverage ratio of more than 1.5:1.0 after giving effect to the incurrence of the debt. The indenture also restricts the ability of the Operating Partnership and its subsidiaries to incur secured debt unless the Operating Partnership and its consolidated subsidiaries comply with a secured debt leverage ratio not to exceed 40% after giving effect to the incurrence of the debt. The indenture also contains other financial and customary covenants, including a covenant not to own unencumbered assets with a value less than 150% of the unsecured indebtedness of the Operating Partnership and its consolidated subsidiaries. As of and for the three and six months ended June 30, 2026, the Operating Partnership was in compliance with all of the financial covenants under the Senior Notes.

8. REVOLVING CREDIT FACILITY

On June 24, 2026, the Company amended and restated, in its entirety, its unsecured revolving credit agreement (the “Third Amended and Restated Credit Facility”) which, subsequent to the amendment and restatement, is comprised of a $1.0 billion unsecured revolving credit facility (the “Revolver”) maturing on June 24, 2030. The Third Amended and Restated Credit Facility provides for two six-month options to extend the maturity date to, at the latest, June 2031 upon the satisfaction of certain conditions. Under the Third Amended and Restated Credit Facility, pricing on the Revolver is dependent upon the Company’s unsecured debt credit ratings and leverage levels. At the Company’s current unsecured debt credit ratings and leverage levels, amounts drawn under the Revolver are priced using a margin of 0.775% plus a facility fee of 0.15% over the Secured Overnight Financing Rate.

As of June 30, 2026, the Revolver had an effective interest rate of 4.61%. Additionally, as of June 30, 2026, $548.5 million was available for borrowing under the Revolver. The available balance under the Revolver is reduced by outstanding letters of credit totaling $0.7 million.

Under the Third Amended and Restated Credit Facility, the Company’s ability to borrow under the Revolver is subject to ongoing compliance with certain financial covenants which include, among other things, (1) a maximum total indebtedness to total asset value of 60.0%, and (2) a minimum fixed charge coverage ratio of 1.5:1.0. As of and for the three and six months ended June 30, 2026, the Operating Partnership was in compliance with all financial covenants of the Third Amended and Restated Credit Facility and its predecessor agreement, the Second Amended and Restated Credit Facility.

11. RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS

The Company is exposed to credit risk with regard to its cash accounts. The Company holds deposits at certain financial institutions in excess of Federal Deposit Insurance Corporation limits. The Company’s cash accounts are held with major financial institutions and management believes that the risk of loss due to disruption at these financial institutions is low. 

23

Table of Contents

The Company’s use of derivative instruments is limited to the utilization of interest rate swap agreements or other instruments to manage interest rate risk exposures and not for speculative purposes. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure, as well as to hedge specific transactions. The counterparties to these arrangements are major financial institutions with which the Company and its subsidiaries may also have other financial relationships. The Company is potentially exposed to credit loss in the event of non-performance by these counterparties. However, because of the high credit ratings of the counterparties, the Company does not anticipate that any of the counterparties will fail to meet these obligations as they come due. The Company does not hedge credit or property value market risks.

The Company formally assesses, both at inception of a hedge and on an on-going basis, whether each derivative is highly effective in offsetting changes in cash flows of the hedged item. If management determines that the derivative is highly effective as a hedge, then the Company accounts for the derivative using hedge accounting, pursuant to which gains or losses inherent in the derivative do not impact the Company’s results of operations. If management determines that the derivative is not highly effective as a hedge or if a derivative ceases to be a highly-effective hedge, the Company discontinues hedge accounting prospectively and reflects within its consolidated statements of operations realized and unrealized gains and losses with respect to the derivative. As of June 30, 2026 and December 31, 2025, all derivative instruments entered into by the Company had been settled.

On December 24, 2018, the Company entered into interest rate swap agreements with notional amounts that aggregated to $150.0 million (the “Interest Rate Swaps”) to protect the Company against adverse fluctuations in interest rates by reducing exposure to variability in cash flows relating to interest payments on a forecasted issuance of long-term debt. The Interest Rate Swaps qualified and were designated as cash flow hedges. Accordingly, the Interest Rate Swaps were recorded on the Company’s consolidated balance sheets at fair value and the related gains or losses were deferred in shareholders’ equity as accumulated other comprehensive income or loss. These deferred gains and losses were amortized into interest expense during the period or periods in which the related interest payments affected earnings. On January 24, 2019, in conjunction with the issuance of $350.0 million of outstanding 4.375% senior notes due 2029 (the “2029 Notes”), the Company settled the Interest Rate Swaps for $0.8 million. The $0.8 million termination premium will be reclassified from accumulated other comprehensive loss as an increase to interest expense over the life of the 2029 Notes, which mature on February 15, 2029. The change in unrealized losses on interest rate swaps reflects a reclassification of twenty thousand dollars and forty thousand dollars of unrealized losses from accumulated other comprehensive loss as an increase to interest expense during the three and six months ended June 30, 2026, respectively. The Company estimates that $0.1 million will be reclassified as an increase to interest expense in the next 12 months.

12. FAIR VALUE MEASUREMENTS

The Company applies the methods of determining fair value as described in authoritative guidance, to value its financial assets and liabilities. As defined in the guidance, fair value is based on the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, the guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

24

Table of Contents

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, as well as considering counterparty credit risk in its assessment of fair value.

The fair values of financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, other financial instruments included in other assets, accounts payable, accrued expenses and other liabilities approximate their respective carrying values at June 30, 2026 and December 31, 2025.

The following table summarizes the carrying value and estimated fair value of the Company’s debt as of June 30, 2026 and December 31, 2025:

The fair value of debt estimates were based on a discounted cash flow analysis assuming market interest rates for comparable obligations as of June 30, 2026 and December 31, 2025. The Company estimates the fair value of its fixed-rate debt and the credit spreads over variable market rates on its variable-rate debt by discounting the future cash flows of each instrument at estimated market rates or credit spreads consistent with the maturity of the debt obligation with similar credit policies, which is classified within Level 2 of the fair value hierarchy. Rates and credit spreads take into consideration general market conditions and the respective debt maturities.

13. NONCONTROLLING INTERESTS

Interests in Consolidated Joint Ventures

Noncontrolling interests in subsidiaries represent the ownership interests of third parties in the Company’s consolidated joint ventures. All consolidated joint ventures were formed to develop, own and operate new stores with the exception of Anoka and Hines (both defined below), which both owned existing stores that had commenced operations prior to the Company’s acquisition of its ownership interest. The following table summarizes the Company’s consolidated joint ventures, each of which are accounted for as VIEs:

Operating Partnership Ownership

During the six months ended June 30, 2026, 19,011 OP Units were redeemed for cash. No OP Units were redeemed during the three months ended June 30, 2026. During the three and six months ended June 30, 2025, 38,965 and 91,465 OP units were redeemed for common shares of the Company, respectively.

As of June 30, 2026 and December 31, 2025, 984,229 and 1,003,240 OP Units, respectively, were owned by third parties. The per unit cash redemption amount of the outstanding OP Units owned by third parties was calculated based upon the closing price of the common shares of CubeSmart on the New York Stock Exchange on the final trading day of the quarter. Based on the Company’s evaluation of the redemption value of the redeemable noncontrolling interests, the Company has reflected these interests at the greater of the carrying value based on the accumulation of historical cost or the redemption value as of June 30, 2026 and December 31, 2025. The aggregate redemption value of the 984,229 OP Units owned by third parties as of June 30, 2026 was $39.1 million.

14. SEGMENT INFORMATION

Overview

The Company has one operating segment: the ownership, operation, development, management, and acquisition of self-storage properties (the “self-storage segment”). Accordingly, the self-storage segment is the Company’s only reportable segment. The self-storage segment derives substantially all of its revenue from customers who lease self-storage space at the Company’s self-storage properties and fees earned from managing self-storage properties. Expenses incurred by the segment are directly related to the revenue-generating activities, the depreciation and amortization of the Company’s assets, and other expenses incurred for the administration and financing of the Company’s operations.

The accounting policies applicable to the self-storage segment are the same as those described in the summary of significant accounting policies included in note 2 to the consolidated financial statements included in the Parent Company’s and Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2025. The Company does not have intra-entity sales or transfers. The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer.

In determining the Company’s operating segment, management considered the reports and information that the CODM reviews, the Company’s organizational structure, the basis of the Company’s incentive compensation, and the information discussed on the Company’s earnings calls and presented on its website. After such analysis, management determined that the Company is primarily and fundamentally managed at the consolidated level, with one operating segment.

Segment Assets

The CODM does not regularly review total assets for our single reportable segment as total assets are not used to assess performance or allocate resources.

Segment Profit or Loss

As a single-segment entity, the Company’s measure of segment profit or loss is net income, which is reported on the Company’s consolidated statements of operations. This measure includes all of the Company’s revenues and expenses, allowing the CODM to evaluate the self-storage segment’s overall performance and informing the CODM’s decisions to allocate resources to different operational, investing and financing aspects of the self-storage segment.

15. COMMITMENTS AND CONTINGENCIES

Development Commitments

As of June 30, 2026, the Company had an agreement with a developer for the construction of one new self-storage property (see note 4), with remaining payments anticipated to approximate $19.3 million. These amounts are due in installments upon completion of certain construction milestones.

Litigation

From time to time, the Company is involved in claims which arise in the ordinary course of business. In accordance with applicable accounting guidance, management establishes an accrued liability for claim expenses, insurance retention and litigation costs when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be exposure to loss in excess of those 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. In the opinion of management, the Company has made adequate provisions for potential liabilities arising from any such matters, which are included in Accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets.

16. RELATED PARTY TRANSACTIONS

The Company provides management services to certain joint ventures and other related parties. Management agreements provide for fee income to the Company based on a percentage of revenues at the managed stores. Total management fees for unconsolidated real estate ventures or other entities in which the Company held an ownership interest totaled $0.7 million and $1.3 million for the three and six months ended June 30, 2026, respectively, compared to $0.6 million and $1.5 million, respectively, during the same periods in 2025.

27

Table of Contents

The management agreements for certain joint ventures, other related parties and third-party stores provide for the reimbursement to the Company for certain expenses incurred to manage the stores. These reimbursements consist of amounts due for management fees, payroll, and other store expenses. The amounts due to the Company were $26.5 million and $19.2 million as of June 30, 2026 and December 31, 2025, respectively, and are included in Other assets, net on the Company’s consolidated balance sheets. Additionally, the Company had outstanding mortgage loans receivable from consolidated joint ventures of $259.0 million and $232.5 million as of June 30, 2026 and December 31, 2025, respectively, which are eliminated for consolidation purposes. The Company believes that all of these related-party amounts are fully collectible.

The CBPR, HVP V, HVP IV and HHFNE operating agreements provide for acquisition, disposition and other fees payable from CBPR, HVP V, HVP IV and HHFNE to the Company upon the closing of certain property transactions by CBPR, HVP V, HVP IV and HHFNE or any of their subsidiaries and completion of certain measures as defined in the operating agreements. There were no such fees recognized during the three or six months ended June 30, 2026 or 2025.

Prior to the Company’s purchase of the remaining interest in HVP IV (see note 4), the Company served as lessor in a ground lease related to land underlying an HVP IV property located in Texas. The Company recognized income associated with this ground lease of $0.1 million during the six months ended June 30, 2025. No income associated with this ground lease was recognized during the three months ended June 30, 2025 or the three and six months ended June 30, 2026. This income is included in the component of other (expense) income designated as Other within the Company’s consolidated statements of operations.

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

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this Report. Some of the statements we make in this section 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 Report entitled “Forward-Looking Statements.” Certain risk factors may cause actual results, performance or achievements to differ materially from those expressed or implied by the following discussion. For a complete discussion of such risk factors, see the section entitled “Risk Factors” in the Parent Company’s and Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2025.

Overview

We are an integrated self-storage real estate company, and as such we have in-house capabilities in the design, development, acquisition, operation, leasing, and management of self-storage properties. The Parent Company’s operations are conducted solely through the Operating Partnership and its subsidiaries. The Parent Company has elected to be taxed as a REIT for U.S. federal income tax purposes. As of June 30, 2026 and December 31, 2025, we owned (or partially owned and consolidated) 662 self-storage properties containing an aggregate of approximately 48.5 million rentable square feet and 662 self-storage properties containing an aggregate of approximately 48.4 million rentable square feet, respectively. As of June 30, 2026, we owned stores in the District of Columbia and the following 25 states: Arizona, California, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah and Virginia. In addition, as of June 30, 2026, we managed 872 stores for third parties (including 50 stores containing an aggregate of approximately 3.4 million rentable square feet as part of six separate unconsolidated real estate ventures) bringing the total number of stores we owned and/or managed to 1,534. As of June 30, 2026, we managed stores for third parties in the following 41 states: Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia, Washington and Wisconsin.

We derive substantially all of our revenue from customers who lease self-storage space at our stores and fees earned from managing stores. Therefore, our operating results depend materially on our ability to retain our existing customers and lease our available self-storage units to new customers while maintaining and, where possible, increasing our pricing levels. In addition, our operating results depend on the ability of our customers to make required rental payments to us. Our approach to the management and operation of our stores combines centralized marketing, revenue management and other operational support with local operations teams that provide market-level oversight and management. We believe this approach allows us to respond quickly and effectively to changes in local market conditions and maximize revenues by managing rental rates and occupancy levels.

We typically experience seasonal fluctuations in the occupancy levels of our stores, which are generally slightly higher during the summer months due to increased moving activity.

Our results of operations may be sensitive to changes in overall economic conditions that impact consumer spending, including discretionary spending and moving trends, as well as to increased bad debts due to economic pressures. Adverse economic conditions affecting disposable consumer income, such as employment levels, business conditions, inflation, deflation, tariffs, interest rates, tax rates, fuel and energy costs, and other matters could reduce consumer spending or cause consumers to shift their spending to other products and services. A general reduction in the level of discretionary spending or shifts in consumer discretionary spending could adversely affect our growth and profitability.

We continue our focus on maximizing internal growth opportunities and selectively pursuing targeted acquisitions, co-investment partnerships and developments of self-storage properties.

We have one operating segment: we own, operate, develop, manage and acquire self-storage properties.

Table of Contents

Our self-storage properties are located in major metropolitan and suburban areas and have numerous customers per store. No single customer represents a significant concentration of our revenues for the three months ended June 30, 2026. Our stores in New York, Florida, Texas and California provided approximately 18%, 13%, 11% and 10%, respectively, of total revenues for the six months ended June 30, 2026.

Summary of Critical Accounting Policies and Estimates

Set forth below is a summary of the accounting policies and estimates that management believes are critical to the preparation of the unaudited consolidated financial statements included in this Report. Certain of the accounting policies used in the preparation of these unaudited consolidated financial statements are particularly important for an understanding of the financial position and results of operations presented in this Report. For additional discussion of the Company’s significant accounting policies, see note 2 to the consolidated financial statements included in the Parent Company’s and Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2025. These policies require the application of judgment and assumptions by management and, as a result, are subject to a degree of uncertainty. Due to this uncertainty, actual results could differ materially from estimates calculated and utilized by management.

Basis of Presentation

The accompanying unaudited consolidated financial statements include all of the accounts of the Company, and its majority-owned and/or controlled subsidiaries. The portion of these entities not owned by the Company is presented as noncontrolling interests as of and during the periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation.

When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity (“VIE”), and if the Company is deemed to be the primary beneficiary, in accordance with authoritative guidance issued by the Financial Accounting Standards Board (“FASB”) on the consolidation of VIEs. To the extent that the Company (i) has the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE and (ii) has the obligation or rights to absorb the VIE’s losses or receive its benefits, then the Company is considered the primary beneficiary. The Company may also consider additional factors included in the authoritative guidance, such as whether or not it is the partner in the VIE that is most closely associated with the VIE. When an entity is not deemed to be a VIE, the Company considers the provisions of additional FASB guidance to determine whether a general partner, or the general partners as a group, controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates (i) entities that are VIEs and of which the Company is deemed to be the primary beneficiary and (ii) entities that are non-VIEs which the Company controls and in which the limited partners do not have substantive participating rights, or the ability to dissolve the entity or remove the Company without cause.

Self-Storage Properties

The Company records self-storage properties at cost less accumulated depreciation. Depreciation on buildings and improvements, as well as equipment is recorded on a straight-line basis over their estimated useful lives, which range from five to 39 years. Expenditures for significant renovations or improvements that extend the useful life of assets are capitalized. Repair and maintenance costs are expensed as incurred.

When stores are acquired, the purchase price is allocated to the tangible and intangible assets acquired and liabilities assumed based on estimated relative fair values.

Allocations to land, buildings and improvements, and equipment are recorded based upon their respective relative fair values as estimated by management. If appropriate, the Company allocates a portion of the purchase price to an intangible asset attributed to the value of in-place leases. This intangible asset is generally amortized to expense over the expected remaining term of the respective leases. Substantially all of the storage leases in place at acquired stores are at market rates, as the majority of the leases are month-to-month contracts. Accordingly, to date, no portion of the purchase price has been allocated to above- or below-market lease intangibles associated with storage leases assumed at acquisition. Above- or below- market lease intangibles associated with assumed leases in which the Company serves as lessee are recorded as an adjustment to the right-of-use asset and reflect the difference between the contractual amounts to be paid pursuant to each in-place lease and management’s estimate of fair market lease rates.

amortized over the term of the lease. To date, no intangible asset has been recorded for the value of customer relationships, because the Company does not have any concentrations of significant customers and the average customer turnover is fairly frequent.

Long-lived assets classified as “held for use” are reviewed for impairment when events or circumstances such as declines in occupancy and operating results indicate that there may be an impairment. The carrying value of these long-lived assets is compared to the undiscounted future net operating cash flows, plus a terminal value, attributable to the assets to determine if the store’s basis is recoverable. If a store’s basis is not considered recoverable, an impairment loss is recorded to the extent the net carrying value of the asset exceeds the fair value. The impairment loss recognized equals the excess of the net carrying value over the related fair value of the asset. There were no impairment losses recognized in accordance with these procedures during the three or six months ended June 30, 2026 and 2025.

The Company considers long-lived assets to be “held for sale” upon satisfaction of the following criteria: (a) management commits to a plan to sell an asset (or group of assets), (b) the asset is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets, (c) an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated, (d) the sale of the asset is probable and transfer of the asset is expected to be completed within one year, (e) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value and (f) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

Typically these criteria are all met when the relevant asset is under contract, significant non-refundable deposits have been made by the potential buyer, the assets are immediately available for transfer and there are no contingencies related to the sale that may prevent the transaction from closing. However, each potential transaction is evaluated based on its separate facts and circumstances. Assets classified as held for sale are reported at the lesser of carrying value or fair value less estimated costs to sell and are not depreciated. There were no stores classified as held for sale as of June 30, 2026.

Investments in Unconsolidated Real Estate Ventures

The Company accounts for its investments in unconsolidated real estate ventures under the equity method of accounting when it is determined that the Company has the ability to exercise significant influence over the venture. Under the equity method, investments in unconsolidated real estate ventures are recorded initially at cost, as investments in real estate entities, and subsequently adjusted for equity in earnings (losses), cash contributions, cash distributions and impairments. On a periodic basis, management also assesses whether there are any indicators that the carrying value of the Company’s investments in unconsolidated real estate entities may be other than temporarily impaired. An investment is impaired only if the fair value of the investment, as estimated by management, is less than the carrying value of the investment and the decline is other than temporary. To the extent impairment that is other than temporary has occurred, the loss shall be measured as the excess of the carrying amount of the investment over the fair value of the investment, as estimated by management. Fair value is determined through various valuation techniques, including, but not limited to, discounted cash flow models, quoted market values and third-party appraisals. There were no impairment losses related to the Company’s investments in unconsolidated real estate ventures recognized during the three or six months ended June 30, 2026 and 2025.

Differences between the Company’s net investment in unconsolidated real estate ventures and its underlying equity in the net assets of the ventures are primarily a result of the Company acquiring interests in existing unconsolidated real estate ventures. As of June 30, 2026 and December 31, 2025, the Company’s net investment in unconsolidated real estate ventures was greater than its underlying equity in the net assets of the unconsolidated real estate ventures by an aggregate of $29.7 million and $30.1 million, respectively. These differences are amortized over the estimated useful lives of the self-storage properties owned by the real estate ventures. This amortization is included in equity in earnings of real estate ventures within our consolidated statements of operations.

Results of Operations

The following discussion of our results of operations should be read in conjunction with our unaudited consolidated financial statements and the accompanying notes thereto. Historical results set forth in our consolidated statements of operations reflect only the existing stores for each period presented and should not be taken as indicative of future operations. We consider our same-store portfolio to consist of only those stores owned and operated on a stabilized basis at the beginning and at the end of the applicable periods presented. We consider a store to be stabilized once it has achieved an occupancy rate that we believe, based on our assessment of market-specific data, is representative of similar self-storage assets in the applicable market for a full year measured as of the most recent January 1 and has not been significantly damaged by natural disaster or undergone significant renovation. We believe that same-store results are useful to investors in evaluating our performance because they provide information relating to changes in store-level operating performance without taking into account the effects of acquisitions, developments or dispositions. As of June 30, 2026, we owned 623 same-store properties and 39 non same-store properties. The non same-store property portfolio results include 2025 and 2026 acquisitions, dispositions, newly developed stores, stores with a significant portion of net rentable square footage taken out of service or stores that have not yet reached stabilization as defined above. For analytical presentation, all percentages are calculated using the numbers presented in the unaudited consolidated financial statements contained in this Report.

Acquisition and Development Activities

The comparability of our results of operations is affected by the timing of acquisition and disposition activities during the periods reported. The following table summarizes the change in the number of owned (or partially owned and consolidated) stores from January 1, 2025 through June 30, 2026:

(1)During the quarter ended March 31, 2026, we completed development of a new store located in New Rochelle, NY for approximately $28.0 million. The developed store is located adjacent to an existing store. Given this proximity, the developed store has been combined with the adjacent existing store in our store count upon opening, as well as for operational and reporting purposes.

Revenues

Total revenues increased from $282.3 million for the three months ended June 30, 2025 to $286.5 million for the three months ended June 30, 2026, an increase of $4.2 million, or 1.5%. This increase was primarily attributable to increased rental rates in our same-store portfolio.

Operating Expenses

Property operating expenses increased from $89.0 million for the three months ended June 30, 2025 to $96.0 million for the three months ended June 30, 2026, an increase of $7.0 million, or 7.9%. This increase was primarily attributable to increases in personnel expense and property taxes.

Depreciation and amortization decreased from $66.5 million for the three months ended June 30, 2025 to $55.8 million for the three months ended June 30, 2026, a decrease of $10.6 million, or 16.0%. This decrease was primarily attributable to decreased amortization of in-place lease intangibles related to stores acquired in 2025.

General and administrative expenses increased from $14.9 million for the three months ended June 30, 2025 to $17.2 million for the three months ended June 30, 2026, an increase of $2.3 million, or 15.8%. This increase was primarily attributable to increases in personnel expense.

Other (Expense) Income

Interest expense on loans increased from $29.1 million during the three months ended June 30, 2025 to $30.3 million during the three months ended June 30, 2026, an increase of $1.3 million, or 4.3%. The increase was attributable to an increase in the average outstanding debt balance and higher interest rates during the 2026 period compared to the 2025 period. The average outstanding debt balance increased from $3.43 billion during the three months ended June 30, 2025 to $3.51 billion during the three months ended June 30, 2026. The weighted average effective interest rate on our

The increase was attributable to an increase in the average outstanding debt balance and higher interest rates during the 2026 period compared to the 2025 period. The average outstanding debt balance increased from $3.31 billion during the six months ended June 30, 2025 to $3.49 billion during the six months ended June 30, 2026. The weighted average effective interest rate on our outstanding debt increased from 3.25% during the six months ended June 30, 2025 to 3.33% for the six months ended June 30, 2026.

Cash provided by operating activities decreased from $303.8 million for the six months ended June 30, 2025 to $293.2 million for the six months ended June 30, 2026, reflecting a decrease of $10.6 million. The decreased cash flow from operating activities was primarily attributable to increased cash paid for interest for the 2026 period as compared to the corresponding 2025 period.

Cash used in investing activities decreased from $491.4 million for the six months ended June 30, 2025 to $27.8 million for the six months ended June 30, 2026, reflecting a change of $463.6 million. This change was primarily the result of $451.1 million paid to acquire the remaining 80% ownership interest in 191 IV CUBE LLC during the 2025 period. There were no acquisitions during the 2026 period.

Cash provided by financing activities was $124.3 million for the six months ended June 30, 2025 compared to $259.0 million of cash used in financing activities for the six months ended June 30, 2026, reflecting a change of $383.3 million. The change was primarily the result of a $294.3 million decrease in net proceeds from our revolving credit facility during the 2026 period as compared to the corresponding 2025 period as well as $75.9 million in payments to repurchase common shares during the 2026 period. There were no such repurchases during the 2025 period.

Liquidity and Capital Resources

Liquidity Overview

Our cash flow from operations has historically been one of our primary sources of liquidity used to fund debt service, distributions and capital expenditures. We derive substantially all of our revenue from customers who lease self-storage space at our stores and fees earned from managing stores. Therefore, our ability to generate cash from operations is dependent on the rents and management fees that we are able to charge and collect from our customers and clients. We believe that the properties in which we invest, self-storage properties, are less sensitive than other real estate product types to changes in economic conditions. However, prolonged economic pressures could adversely affect our cash flows from operations.

In order to qualify as a REIT for federal income tax purposes, the Parent Company is required to distribute at least 90% of its REIT taxable income, excluding capital gains, to its shareholders on an annual basis, and must pay federal income tax on undistributed income to the extent it distributes less than 100% of its REIT taxable income. The nature of our business, coupled with the requirement that we distribute a substantial portion of our income on an annual basis, will cause us to have substantial liquidity needs over both the short and long term.

Our short-term liquidity needs consist primarily of funds necessary to pay operating expenses associated with our stores; repay certain indebtedness; pay interest expense and scheduled principal payments on debt; fund expected distributions to limited partners and shareholders; and fund capital expenditures and the acquisition and development of new stores. These funding requirements will vary from year to year, in some cases significantly. For the remainder of the 2026 fiscal year, we expect recurring capital expenditures to be approximately $12.5 million to $17.5 million, planned capital improvements and store upgrades to be approximately $9.0 million to $14.0 million and costs associated with the development of new stores to be approximately $2.0 to $7.0 million. Our currently scheduled principal payments on our outstanding debt, including the repayment of unsecured senior notes, are approximately $340.4 million for the remainder of 2026.

Our most restrictive financial covenants limit the amount of additional leverage we can add; however, we believe cash flows from operations, access to equity financing, including through our at-the-market equity program, and available borrowings under our Revolver (defined below) provide adequate sources of liquidity to enable us to execute our current business plan and remain in compliance with our covenants.

Our liquidity needs beyond 2026 consist primarily of contractual obligations which include repayments of indebtedness at maturity, as well as potential discretionary expenditures such as (i) non-recurring capital expenditures; (ii) redevelopment of operating stores; (iii) acquisitions of additional stores; and (iv) development of new stores. We will have to satisfy the portion of our needs not covered by cash flow from operations through additional borrowings, including borrowings under our Revolver, sales of common or preferred shares of the Parent Company and common or preferred units of the Operating Partnership and/or cash generated through store dispositions and joint venture transactions.

We believe that, as a publicly traded REIT, we will have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional debt and the issuance of additional equity. However, we cannot provide any assurance that this will be the case. Our ability to incur additional debt will be dependent on a number of factors, including our degree of leverage, the value of our unencumbered assets and borrowing restrictions that may be imposed by lenders. In addition, dislocation in the United States debt markets may significantly reduce the availability and increase the cost of long-term debt capital, including conventional mortgage financing and commercial mortgage-backed securities financing. There can be no assurance that such capital will be readily available in the future. Our ability to access the equity capital markets will be dependent on a number of factors, including general market conditions for REITs and market perceptions about us.

As of June 30, 2026, we had approximately $14.3 million in available cash and cash equivalents. In addition, we had approximately $548.5 million of availability for borrowings under our Revolver.

The indenture under which the Senior Notes were issued restricts the ability of the Operating Partnership and its subsidiaries to incur debt unless the Operating Partnership and its consolidated subsidiaries comply with a leverage ratio not to exceed 60% and an interest coverage ratio of more than 1.5:1.0 after giving effect to the incurrence of the debt. The indenture also restricts the ability of the Operating Partnership and its subsidiaries to incur secured debt unless the Operating Partnership and its consolidated subsidiaries comply with a secured debt leverage ratio not to exceed 40% after giving effect to the incurrence of the debt. The indenture also contains other financial and customary covenants, including a covenant not to own unencumbered assets with a value less than 150% of the unsecured indebtedness of the Operating Partnership and its consolidated subsidiaries. As of and for the three and six months ended June 30, 2026, the Operating Partnership was in compliance with all of the financial covenants under the Senior Notes.

Revolving Credit Facility

On June 24, 2026, we amended and restated, in its entirety, our unsecured revolving credit agreement (the “Third Amended and Restated Credit Facility”) which, subsequent to the amendment and restatement, is comprised of a $1.0 billion unsecured revolving credit facility (the “Revolver”) maturing on June 24, 2030. The Third Amended and Restated Credit Facility provides for two six-month options to extend the maturity date to, at the latest, June 2031 upon the satisfaction of certain conditions. Under the Third Amended and Restated Credit Facility, pricing on the Revolver is dependent upon our unsecured debt credit ratings and leverage levels. At our current unsecured debt credit ratings and leverage levels, amounts drawn under the Revolver are priced using a margin of 0.775% plus a facility fee of 0.15% over the Secured Overnight Financing Rate.

As of June 30, 2026, the Revolver had an effective interest rate of 4.61%. Additionally, as of June 30, 2026, $548.5 million was available for borrowing under the Revolver. The available balance under the Revolver is reduced by outstanding letters of credit totaling $0.7 million.

Under the Third Amended and Restated Credit Facility, our ability to borrow under the Revolver is subject to ongoing compliance with certain financial covenants which include, among other things, (1) a maximum total indebtedness to total asset value of 60.0%, and (2) a minimum fixed charge coverage ratio of 1.5:1.0. As of and for the three and six months ended June 30, 2026, the Operating Partnership was in compliance with all financial covenants of the Third Amended and Restated Credit Facility and its predecessor agreement, the Second Amended and Restated Credit Facility.

At-the-Market Equity Program

On March 3, 2025, we replaced our prior at-the-market equity distribution program with a new at-the-market equity distribution program. Under the new program, we may sell, from time to time, up to an aggregate of 13,510,817 common shares of CubeSmart through agents acting as our sales agents or as forward sellers of common shares borrowed from third parties (if acting as forward sellers). Sales of common shares, if any, made through the agents, as our sales agents, or as forward sellers, may be made by any method permitted by law to be an “at the market” offering as defined in Rule 415 under the Securities Act of 1933, as amended, or by any other method permitted by applicable law. We may also sell common shares to a sales agent, as principal for its own account, at a price to be agreed upon at the time of sale. Actual sales, if any, under the program will depend on a variety of factors to be determined by us from time to time, including, among other things, market conditions, the trading price of our common shares, capital needs and determinations by us of the appropriate sources of our funding. As of June 30, 2026, we had not sold any common shares under the new program.

Repurchase of Common Shares

During the three and six months ended June 30, 2026, we repurchased 1.1 million and 2.0 million common shares of beneficial interest, respectively, under our share repurchase program. The average purchase price was $38.96 per share for the three-month period and $37.90 per share for the six-month period. There were no such repurchases during the three or six months ended June 30, 2025. Additionally, on February 24, 2026, the Company’s Board of Trustees (the “Board”) authorized additional share repurchases of up to 10.0 million of the Parent Company’s outstanding common shares. As of June 30, 2026, 10.1 million common shares remained available for repurchase under this program.

Recent Developments

Subsequent to June 30, 2026, we entered into an agreement to contribute 15 wholly-owned stores to a newly-formed joint venture with an affiliate of Heitman Capital Management (“Heitman”) for an agreed-upon value of $197.0 million. We will receive cash and own a 20% interest in the joint venture, while Heitman will contribute cash and own the remaining 80% interest. The stores subject to the agreement contain approximately 0.9 million square feet and are located in Connecticut (3), Georgia (1), North Carolina (2), Ohio (1), Texas (2), Utah (4) and Virginia (2). The transaction is expected to close in the fourth quarter of 2026.

Non-GAAP Financial Measures

NOI

We define net operating income, which we refer to as “NOI”, as total continuing revenues less continuing property operating expenses. NOI also can be calculated by adding back to net income (loss): interest expense on loans, loan procurement amortization expense, loss on early extinguishment of debt, acquisition-related costs, equity in losses of real estate ventures, other expense, depreciation and amortization expense, general and administrative expense, and deducting from net income (loss): equity in earnings of real estate ventures, gains from sales of real estate, net, other income, gains from remeasurement of investments in real estate ventures and interest income. NOI is not a measure of performance calculated in accordance with GAAP.

We use NOI as a measure of operating performance at each of our stores, and for all of our stores in the aggregate. NOI should not be considered as a substitute for operating income, net income, cash flows provided by operating, investing and financing activities, or other income statement or cash flow statement data prepared in accordance with GAAP.

We believe NOI is useful to investors in evaluating our operating performance because:

it is one of the primary measures used by our management to evaluate the economic productivity of our stores, including our ability to lease our stores, increase pricing and occupancy and control our property operating expenses;

it is widely used in the real estate and self-storage industries to measure the performance and value of real estate assets without regard to various items included in net income that do not relate to or are not indicative of operating performance, such as depreciation and amortization, which can vary depending upon accounting methods and the book value of assets; and

it helps our investors to meaningfully compare the results of our operating performance from period to period by removing the impact of our capital structure (primarily interest expense on our outstanding indebtedness) and depreciation of our basis in our assets from our operating results.

There are material limitations to using a measure such as NOI, including the difficulty associated with comparing results among more than one company and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income. We compensate for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with our analysis of net income. NOI should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues, total operating expenses, and net income.

FFO

Funds from operations (“FFO”) is a widely used performance measure for real estate companies and is provided here as a supplemental measure of operating performance. The April 2002 National Policy Bulletin of the National Association of Real Estate Investment Trusts, as amended and restated, defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of real estate and related impairment charges, plus real estate depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

Management uses FFO as a key performance indicator in evaluating the operations of our stores. Given the nature of our business as a real estate owner and operator, we consider FFO a key measure of our operating performance that is not specifically defined by accounting principles generally accepted in the United States. We believe that FFO is useful to management and investors as a starting point in measuring our operational performance because FFO excludes various items included in net income that do not relate to or are not indicative of our operating performance such as gains (or losses) from sales of real estate, gains from remeasurement of investments in real estate ventures, impairments

40

Table of Contents

of depreciable assets, and depreciation, which can make periodic and peer analyses of operating performance more difficult. Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies.

FFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance. FFO does not represent cash generated from operating activities determined in accordance with GAAP and is not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO should be compared with our reported net income and considered in addition to cash flows computed in accordance with GAAP, as presented in our unaudited consolidated financial statements.

FFO, as adjusted

FFO, as adjusted represents FFO, as defined above, excluding the effects of acquisition related costs, gains or losses from early extinguishment of debt, and non-recurring items, which we believe are not indicative of the Company’s operating results. We present FFO, as adjusted because we believe it is a helpful measure in understanding our results of operations insofar as we believe that the items noted above that are included in FFO, but excluded from FFO, as adjusted are not indicative of our ongoing operating results. We also believe that investors, analysts and other stakeholders consider our FFO, as adjusted (or similar measures using different terminology) when evaluating us. Because other REITs or real estate companies may not compute FFO, as adjusted in the same manner as we do, and may use different terminology, our computation of FFO, as adjusted may not be comparable to FFO, as adjusted reported by other REITs or real estate companies.

The following table presents a reconciliation of net income attributable to the Company’s common shareholders to FFO (and FFO, as adjusted) attributable to the Company’s common shareholders and third-party OP unitholders for the three and six months ended June 30, 2026 and 2025.

Off-Balance Sheet Arrangements

We do not have off-balance sheet arrangements, financings or other relationships with other unconsolidated entities (other than our co-investment partnerships) or other persons, also known as variable interest entities, not previously discussed.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair values relevant to financial instruments depend upon prevailing market interest rates.

Market Risk

Our investment policy relating to cash and cash equivalents is to preserve principal and liquidity while maximizing returns through the investment of available funds.

Effect of Changes in Interest Rates on our Outstanding Debt

Our interest rate risk objectives are to limit the impact of interest rate fluctuations on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, we may, from time to time, choose to manage our exposure to fluctuations in market interest rates for a portion of our borrowings through the use of derivative financial instruments such as interest rate swaps or caps to mitigate our interest rate risk on a related financial instrument or to effectively lock the interest rate on a portion of our variable-rate debt. The analysis below presents the sensitivity of the market value of our financial instruments to selected changes in market interest rates. The range of changes chosen reflects our view of changes which are reasonably possible over a one-year period. Market values are the present value of projected future cash flows based on the market interest rates chosen.

As of June 30, 2026, our consolidated debt consisted of $3.04 billion of outstanding mortgage loans and notes payable and unsecured senior notes that are subject to fixed rates. Additionally, as of June 30, 2026, there were $450.8 million of outstanding unsecured credit facility borrowings subject to floating rates.  Changes in market interest rates have different impacts on the fixed- and variable-rate portions of our debt portfolio. A change in market interest rates on the fixed portion of the debt portfolio impacts the net financial instrument position, but has no impact on interest incurred or cash flows. A change in market interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows, but does not impact the net financial instrument position.

If market interest rates on our variable-rate debt increase by 100 basis points, the increase in annual interest expense on our variable-rate debt would decrease future earnings and cash flows by approximately $4.5 million a year. If market interest rates on our variable-rate debt decrease by 100 basis points, the decrease in interest expense on our variable-rate debt would increase future earnings and cash flows by approximately $4.5 million a year.

If market interest rates increase by 100 basis points, the fair value of our outstanding fixed-rate mortgage debt and unsecured senior notes would decrease by approximately $103.6 million. If market interest rates decrease by 100 basis points, the fair value of our outstanding fixed-rate mortgage debt and unsecured senior notes would increase by approximately $109.5 million.
