(the “Operating Partnership”) owns, directly or indirectly through one or more subsidiaries, all of the self storage properties that we own. As of September 30, 2024, we owned approximately 88% of the common units of limited partnership interests of our Operating Partnership. The remaining approximately 12% of the common units are owned by current and former employees, members of our executive management team, board members, or indirectly by Strategic Asset Management I, LLC (f/k/a SmartStop Asset Management, LLC), our former sponsor (“SAM”), its affiliates, and affiliates of Select Capital Corporation, the former dealer manager of our offering (the “Former Dealer Manager”). As the sole general partner of our Operating Partnership, we have the exclusive power to manage and conduct the business of our Operating Partnership. We commenced our initial public offering in January 2014, in which we offered a maximum of $1.0 billion in common shares for sale to the public (the “Primary Offering”) and $95.0 million in common shares for sale pursuant to our distribution reinvestment plan (collectively, the “Offering”). At the termination of our Offering in January 2017, we had sold approximately 48 million shares of our Class A common stock (the “Class A Shares”) and approximately 7 million shares of our Class T common stock (the “Class T Shares”) for approximately $493 million and $73 million respectively. In November 2016, we filed a Registration Statement on Form S-3 As of September 30, 2024, we had sold approximately 10.3 million Class A Shares and approximately 1.3 million Class T Shares through our distribution reinvestment plan, of which, approximately 0.5 million Class A Shares and approximately 0.1 million Class T Shares were sold under our current DRP Offering. The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. On January 15, 2024, our board of directors (the “Board”), upon recommendation of our Nominating and Corporate Governance Committee, approved an Estimated Per Share Net Asset Value (“NAV”) of our common stock of $15.25 for our Class A Shares and Class T Shares based on the estimated value of our assets less the estimated value of our liabilities, or net asset value, divided by the number of shares outstanding on a fully diluted basis, calculated as of September 30, 2023.

	Sep. 30, 2024	Dec. 31, 2023
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC. The square footage, unit count, and occupancy percentage data and related disclosures included in these notes to the consolidated financial statements are outside the scope of our independent registered accounting firm’s review. Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. Our Operating Partnership is deemed to be a VIE and is consolidated by us as we are currently the primary beneficiary. Our sole significant asset is our investment in our Operating Partnership; as a result, substantially all of our assets and liabilities represent those assets and liabilities of our Operating Partnership and its wholly-owned subsidiaries. Pacific Oak Holding Group, LLC, the parent company of Pacific Oak Capital Markets, LLC, the dealer manager for the public offering of SST VI, is a 17.5% non-voting As of September 30, 2024 and December 31, 2023, we were not a party to any other material contracts or interests that would be deemed variable interests in VIEs other than our joint ventures with SmartCentres, our Nantucket Joint Venture (as defined below), and our equity investments in the Managed REIT’s, which are all accounted for under the equity method of accounting (see Note 4 – Investments in Unconsolidated Real Estate Ventures and Note 10 – Related Party Transactions for additional information), and our joint venture programs through which we offer our tenant insurance, tenant protection plans or similar programs (the “Tenant Protection Programs”) with SST VI, SSGT III, and SSGT II (through June 1, 2022) which are consolidated. Equity Investments Under the equity method, our investments are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and impairments, as applicable. Equity in earnings will generally be recognized based on our ownership interest in the earnings of each of the unconsolidated investments and recorded within our consolidated statements of operations. Investments in and Advances to Managed REITs As of September 30, 2024 and December 31, 2023, we had both equity and debt investments in the Managed REITs; such amounts are included in Investments in and advances to Managed REITs within our consolidated balance sheets. We account for the equity investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. We record the interest and related financing fees on our debt investments on the accrual basis and such income was previously included in Other, net, within our consolidated statements of operations. Such income has been reclassified to Interest income within the consolidated statements of operations included herein. While we do make loans periodically, we do not consider that to be part of our primary operating activity, and therefore do not report income from loans as operating income. See Note 10 – Related Party Transactions for additional information. Noncontrolling Interests in Consolidated Entities We account for the noncontrolling interests in our Operating Partnership and the noncontrolling interests in SST VI Advisor and our Tenant Protection Programs joint ventures with SST VI, SSGT III, and SSGT II (prior to the SSGT II Merger on June 1, 2022) in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interests are reflected as noncontrolling interests in the accompanying consolidated balance sheets. We also consolidate our interests in the SSGT III and SST VI Tenant Protection Programs and present the minority interests as noncontrolling interests in the accompanying consolidated balance sheets. The noncontrolling interests shall be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interests balance. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management will adjust such estimates when facts and circumstances dictate. Actual results could materially differ from those estimates. The most significant estimates made include that of real estate acquisition valuation and the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed at relative fair value, the evaluation of potential impairment of indefinite and long-lived assets and goodwill, and the estimated useful lives of real estate assets and intangibles. Cash and Cash Equivalents We consider all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. We may maintain cash and cash equivalents in financial institutions in excess of insured limits. In an effort to mitigate this risk, we only invest in or through major financial institutions. Restricted Cash Restricted cash consists primarily of impound reserve accounts for property taxes, insurance and capital improvements in connection with the requirements of certain of our loan agreements. Real Estate Purchase Price Allocation and Treatment of Acquisition Costs We account for asset acquisitions in accordance with GAAP which requires that we allocate the purchase price of a property to the tangible and intangible assets acquired and the liabilities assumed based on their relative fair values as of the date of acquisition. This guidance requires us to make significant estimates and assumptions, including fair value estimates, which requires the use of significant unobservable inputs as of the acquisition date. We engage independent third-party valuation specialists to assist in the determination of significant estimates and market-based assumptions used in the valuation models. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month in-place, in-place Allocation of purchase price to acquisitions of portfolios of facilities are allocated to the individual facilities based upon an income approach or a cash flow analysis using appropriate risk adjusted capitalization rates which take into account the relative size, age, and location of the individual facility along with current and projected occupancy and rental rate levels or appraised values, if available. Acquisitions that do not meet the definition of a business, as defined under current GAAP, are accounted for as asset acquisitions. During the nine months ended September 30, 2024 and 2023, our property acquisitions did not meet the definition of a business. To date, our acquisitions have generally not met the definition of a business because substantially all of the fair value was concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) and because the acquisitions did not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. As a result, once an acquisition is deemed probable, acquisition related transaction costs are capitalized rather than expensed. During the three months ended September 30, 2024 and 2023, we expensed approximately $38,000 and $76,000, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods. During the nine months ended September 30, 2024 and 2023, we expensed approximately $121,000 and $118,000, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods. Evaluation of Possible Impairment of Real Property Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our real property assets may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the real property assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the real property assets to the fair value and recognize an impairment loss. For the nine months ended September 30, 2023, no real property asset impairment losses were recognized. For the nine months ended September 30, 2024, we recorded a casualty loss in connection with damage to one of our wholly-owned properties caused by Hurricane Helene. Please see Note 3 – Real Estate for additional detail. Casualty Insurance Recoveries In the event of a wind storm, flood, fire or other such event causing property damage, we estimate the carrying value of the damaged property and record a corresponding casualty loss. If we determine that an insurance recovery is probable, we record such estimated recovery as a receivable up to the amount of the casualty loss. Any amount of insurance recovery for such loss in excess of the amount of the casualty loss recorded is considered a gain contingency and is recognized when the claim is fully settled. Goodwill Valuation We initially recorded goodwill as a result of the Self Administration Transaction (as defined in Note 10 – Related Party Transactions), which occurred in 2019. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable, and is not amortized. We perform an annual qualitative impairment assessment as of December 31 for goodwill; between annual tests we evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. If circumstances indicate the carrying amount may not be fully recoverable, we perform a quantitative analysis to compare the fair value of each reporting unit to its respective carrying amount. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized. Trademarks In connection with the Self Administration Transaction, we recorded the fair value associated with the two primary trademarks acquired therein. Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible fair value of our ownership of the brand name. As of September 30, 2024 and December 31, 2023, $15.7 million was recorded related to the SmartStop ® ® ® We qualitatively evaluate whether any triggering events or changes in circumstances have occurred in addition to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuation methods is adversely impacted, the impact could result in a material impairment charge in the future. Revenue Recognition Self Storage Operations Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. In accordance with ASC 842, we review the collectability of lease payments on an ongoing basis. We consider collectability indicators when analyzing accounts receivable and historical bad debt levels, including current economic trends, all of which assist in evaluating the probability of outstanding and future rental income collections. Additionally, we earn ancillary revenue from fees we receive related to providing tenant insurance or tenant protection plans to customers at our properties through our Tenant Protection Programs, and to a lesser extent, through the sale of various moving and packing supplies such as locks and boxes. We recognize such revenue in the Ancillary operating revenue line within our consolidated statements of operations as the services are performed and as the goods or services are delivered. Managed REIT Platform We earn property management and asset management revenue, pursuant to the respective property management and advisory agreement contracts, in connection with providing services to the Managed REITs. We have determined under ASC 606 – Revenue from Contracts with Customers (“ASC 606”), that the performance obligation for the property management services and asset management services are satisfied as the services are rendered. While we are compensated for our services on a monthly basis, these services represent a series of distinct daily services in accordance with ASC 606. Such revenue is recorded in the Managed REIT Platform revenue line within our consolidated statements of operations. The Managed REITs’ advisory agreements also provide for reimbursement to us of our direct and indirect costs of providing administrative and management services to the Managed REITs. These reimbursements include costs incurred in relation to organization and offering services provided to the Managed REITs and the reimbursement of salaries, bonuses, and other expenses related to benefits paid to our employees while performing services for the Managed REITs. The Managed REITs’ property management agreements also provide reimbursement to us for the property manager’s costs of managing the properties. Reimbursable costs include wages and salaries and other expenses that arise in operating, managing and maintaining the Managed REITs’ properties. Under ASC 606, direct reimbursement of such costs does not represent a separate performance obligation from our obligation to perform property management and asset management services. The reimbursement income is considered variable consideration, and is recognized as the costs are incurred, subject to limitations on the Managed REIT Platform’s ability to incur offering costs or limitations imposed by the advisory agreements. We have elected to separately record such revenue in the Reimbursable costs from Managed REITs line within our consolidated statements of operations. Additionally, we earn revenue in connection with our Tenant Protection Programs joint ventures with our Managed REITs. We also earn development and construction management revenue from services we provide in connection with the project design, coordination and oversight of development and certain capital improvement projects undertaken by the Managed REITs. We recognize such revenue in the Managed REIT Platform revenue line within our consolidated statements of operations as the services are performed or delivered. See Note 10 – Related Party Transactions, for additional information regarding revenue generated from our Managed REIT Platform. Sponsor Funding Agreement On November 1, 2023, SmartStop REIT Advisors, LLC, a subsidiary of our Operating Partnership, entered into a sponsor funding agreement (the “Sponsor Funding Agreement”) with SST VI and Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”) in connection with certain changes to the public offering of SST VI (see Note 10 – Related Party Transactions for additional information). Pursuant to the Sponsor Funding Agreement, SmartStop, through a wholly-owned subsidiary, is required to fund the payment of the front-end sales load for the sale of SST VI’s class Y and class Z shares sold in its offering. In exchange, SmartStop receives a number of series C convertible units (“Series C Units”) in SST VI OP calculated as the dollar amount of such funding divided by the then-current offering price, which was $9.30 through August 6, 2024 for such class Y and Z shares. The Series C Units shall automatically convert into class A units of SST VI OP on a one-to-one basis upon SST VI’s disclosure of an estimated net asset value per share equal to at least $10.00 per share for each class of SST VI shares of common stock, including the class Y shares and class Z shares, calculated net of the Series C Units to be converted. On August 7, 2024, SST VI declared an estimated net asset value per share of $10.00. Since the Series C Units that could be converted would result in the net asset value falling below $10.00 per share, none of the Series C Units we own were converted into class A units of SST VI OP, and our future purchases will be determined based on the current estimated net asset value at such time. Subsequent to SST VI declaring an estimated net asset value of $10.00 per share, the number of Series C Units SmartStop receives in exchange for funding the front-end sales load of the sale of SST VI’s class Y and class Z shares is calculated as the dollar amount of such sponsor funding divided by the current offering price of $10.00 per share for such class Y and Z shares. In accordance with ASC 606, the amount by which our funding exceeds the fair value of the Series C Units received is accounted for as a payment to a customer and is therefore recorded as a reduction to the transaction price for the services we provide to such customer. Each payment is initially included in the Other assets line-item in our consolidated balance sheet and subsequently recorded as a reduction of Managed REIT Platform revenues ratably over the remaining estimated life of our management contracts with SST VI. Below is a summary of the portion of sponsorship funding payments which exceeds the fair value of the Series C Units received, and is recorded pursuant to ASC 606 as described above (in thousands): Balance as of December 31, 2022 $ —  Amounts incurred 3,527 Recorded sponsor funding reduction (34 ) Balance as of December 31, 2023 $ 3,493 Amounts incurred $ 932 Recorded sponsor funding reduction (598 ) Balance as of September 30, 2024 $ 3,827 Allowance for Doubtful Accounts Tenant accounts receivable is reported net of an allowance for doubtful accounts. Management records this general allowance estimate based upon a review of the current status of accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future. As of September 30, 2024 and December 31, 2023, approximately $1.0 million and $0.9 million, respectively, were recorded to allowance for doubtful accounts and are included within other assets in the accompanying consolidated balance sheets. Advertising Costs Advertising costs are expensed in the period in which the cost is incurred and are included in property operating expenses and general and administrative lines within our consolidated statements of operations, depending on the nature of the expense. We incurred advertising costs of approximately $1.3 million and $1.2 million for the three months ended September 30, 2024 and 2023, respectively, within property operating expenses, and approximately $0.7 million and $0.5 million for the three months ended September 30, 2024 and 2023, respectively, within general and administrative. We incurred advertising costs of approximately $4.0 million and $3.6 million for the nine months ended September 30, 2024 and 2023, respectively, within property operating expenses, and approximately $1.7 million and $1.6 million for the nine months ended September 30, 2024 and 2023, respectively, within general and administrative. Real Estate Facilities We capitalize costs incurred to develop, construct, renovate and improve properties, including interest and property taxes incurred during the construction period. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use. Depreciation of Real Property Assets Our management is required to make subjective assessments as to the useful lives of our depreciable assets. We consider the period of future benefit of the asset to determine the appropriate useful lives. Depreciation of our real property assets is charged to expense on a straight-line basis over the estimated useful lives as follows: Description Standard Depreciable Life Land Not Depreciated Buildings 30-40 Site Improvements 7-10 Depreciation of Personal Property Assets Personal property assets consist primarily of furniture, fixtures and equipment and are depreciated on a straight-line basis over the estimated useful lives, generally ranging from 3 to 5 years, and are included in other assets on our consolidated balance sheets. Intangible Assets We have allocated a portion of our real estate purchase price to in-place The total estimated future amortization expense related to intangible assets for the years ending December 31, 2024, 2025, 2026, 2027, 2028, and thereafter is approximately $0.3 million, $1.2 million, $0.2 million, $0.1 million, $0.1 million, and $0.6 million thereafter, respectively. The weighted-average amortization period on our remaining intangible assets with a net book value of approximately $2.6 million was approximately 3.2 years as of September 30, 2024. We evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuations methods is adversely impacted, the impact could result in an impairment charge in the future. Debt Issuance Costs The net carrying value of costs incurred in connection with obtaining non revolving debt are presented on the balance sheet as a deduction from debt; amounts incurred related to obtaining revolving debt are included in the debt issuance costs line on our consolidated balance sheet. See Note 5 – Debt for additional information. Debt issuance costs are amortized using the effective interest method. As of September 30, 2024 the gross amount of debt issuance costs related to our revolving credit facility totaled approximately $9.3 million and accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $1.8 million. As of December 31, 2023, the gross amount of debt issuance costs related to our revolving credit facility totaled approximately $4.5 million, and accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $4.1 million. As of September 30, 2024, the gross amount allocated to debt issuance costs related to non-revolving debt totaled approximately $6.0 million and accumulated amortization of debt issuance costs related to non-revolving debt totaled approximately $2.7 million. As of December 31, 2023, the gross amount allocated to debt issuance costs related to non-revolving non-revolving Foreign Currency Translation For non-U.S. investments Redeemable Common Stock We adopted a share redemption program (“SRP”) that enables stockholders to sell their shares to us in limited circumstances. We have evaluated the terms of our SRP, and we classify amounts that are redeemable under the SRP as redeemable common stock in the accompanying consolidated balance sheets. The maximum amount of redeemable shares under our SRP is limited to the net proceeds from the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation of us to repurchase shares be classified as liabilities and reported at settlement value. When we determine we have a mandatory obligation to repurchase shares under the SRP, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. See Note 12 – Commitments and Contingencies for additional information on our SRP. Accounting for Equity Awards We issue equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”), both of which may be issued subject to either time based vesting criteria or performance based vesting criteria restrictions. For time based awards granted which contain a graded vesting schedule, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For performance based awards, compensation cost is recognized over the requisite service period if and when we determine the performance condition is probable of being achieved. We record the cost of such equity based awards based on the grant date fair value, and have elected to record forfeitures as they occur. Employee Benefit Plan The Company maintains its own retirement savings plan under Section 401(k) of the Internal Revenue Code, as amended (the “Code”), under which eligible employees can contribute up to 100% of their annual salary, subject to a statutory prescribed annual limit. The Company matches 100% on contributions up to the first 4% of an employee’s compensation. Fair Value Measurements Under GAAP, we are required to measure certain financial instruments at fair value on a recurring basis. In addition, we are required to measure other financial instruments and balances at fair value on a non-recurring • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; • Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and • Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety. The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we will utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment will be necessary to interpret Level 2 and 3 inputs in determining fair value of our financial and non-financial Financial and non-financial non-recurring along with the assets and liabilities described in Note 3 – Real Estate Facilities. The fair values of these assets and liabilities were determined as of the acquisition dates using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) market approach, which considers comparable sales activity. Additionally, certain such assets and liabilities are required to be fair valued periodically or valued pursuant to ongoing fair value requirements and impairment analyses and have been valued subsequently utilizing the same techniques noted above. In general, we consider multiple valuation techniques when measuring fair values. However, in certain circumstances, a single valuation technique may be appropriate. All of the fair values of the assets and liabilities as of the acquisition dates were derived using Level 3 inputs. The Series C Units (categorized within Level 3 of the fair value hierarchy) acquired in connection with the Sponsor Funding Agreement are measured at fair value at the time of acquisition, and are accounted for using the equity method of accounting as described in Note 10 – Related Party Transactions. The fair value of these units were determined upon purchase using a valuation model which considered the following key assumptions: the projected distribution rate of SST VI, implied share price volatility, risk free interest rate, current estimated net asset value, and the estimated effective life of the Series C Units. The carrying amounts of cash and cash equivalents, restricted cash, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates approximate fair value (categorized within Level 1 of the fair value hierarchy). The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with eac	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC. Unaudited Information The square footage, unit count, and occupancy percentage data and related disclosures included in these notes to the consolidated financial statements are unaudited. Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”), the operating partnership of SST VI, and its wholly-owned subsidiaries, were consolidated by us from March 10, 2021 (the date of our initial investment in SST VI OP) until May 1, 2021. The portion not wholly-owned by us was presented as noncontrolling interests, and all intercompany accounts and transactions were eliminated when they were consolidated by us. Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. Our Operating Partnership is deemed to be a VIE and is consolidated by the Company as we are currently the primary beneficiary. Our sole significant asset is our investment in our Operating Partnership; as a result, substantially all of our assets and liabilities represent those assets and liabilities of our Operating Partnership and its wholly-owned subsidiaries. From March 10, 2021 until May 1, 2021, we were deemed to be the primary beneficiary of SST VI OP, and their operations were therefore consolidated by us. Subsequent to May 1, 2021, we are no longer the primary beneficiary, and their operations are no longer consolidated by us. On March 1, 2022, Pacific Oak Holding Group, LLC, the parent company of Pacific Oak Capital Markets, LLC, the dealer manager for the public offering of SST VI, became a 10% non-voting As of December 31, 2023, we were not a party to any other material contracts or interests that would be deemed variable interests in VIEs other than our joint ventures with SmartCentres and our equity investments in the Managed REIT’s, which are all accounted for under the equity method of accounting (see Note 4 – Investments in Unconsolidated Real Estate Ventures and Note 10 - Related Party Transactions for additional information), and our joint venture programs through which we offer our tenant insurance, tenant protection plans or similar programs (the “Tenant Protection Programs”) with SST VI, SSGT III, and SSGT II (through June 1, 2022) which are consolidated. Equity Investments Under the equity method, our investments are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and impairments, as applicable. Equity in earnings will generally be recognized based on our ownership interest in the earnings of each of the unconsolidated investments and recorded within our consolidated statements of operations. Our share of earnings and losses from our equity method investments in the JV Properties (as defined in Note 4 - Investments in Unconsolidated Real Estate Ventures) was previously included in Other, net within our consolidated statements of operations, but has been reclassified to Equity in earnings (losses) from investments in JV Properties within the current consolidated statements of operations included herein. Investments in and Advances to Managed REITs As of December 31, 2023, and 2022, we owned equity and debt investments in the Managed REITs; such amounts are included in Investments in and advances to Managed REITs within our consolidated balance sheets. We account for the equity investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the respective Managed REIT’s earnings and reduced by distributions. Our share of earnings and losses from our equity method investments in the Managed REITs was previously included in Other, net within our consolidated statements of operations, but has been reclassified to Equity in earnings (losses) from investments in Managed REITs within our current consolidated statements of operations included herein. We record the interest on our debt investments on the accrual basis and such income is included in Other, net, within Other income (expense) of our consolidated statements of operations. While we do make loans periodically, we do not consider that to be part of our ordinary operating activity, and therefore do not report income from loans as operating income. See Note 10 – Related Party Transactions for additional information. Noncontrolling Interests in Consolidated Entities We account for the noncontrolling interests in our Operating Partnership and the noncontrolling interests in SST VI Advisor and our Tenant Protection Programs joint ventures with SST VI, SSGT III, and SSGT II (prior to the SSGT II Merger on June 1, 2022) in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interests are reflected as noncontrolling interests in the accompanying consolidated balance sheets. We also consolidate our interests in the SSGT III and SST VI Tenant Protection Programs and present the minority interests as noncontrolling interests in the accompanying consolidated balance sheets. The noncontrolling interests shall be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interests balance. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management will adjust such estimates when facts and circumstances dictate. Actual results could materially differ from those estimates. The most significant estimates made include that of real estate acquisition valuation and the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed at relative fair value, the evaluation of potential impairment of indefinite and long-lived assets and goodwill, and the estimated useful lives of real estate assets and intangibles. Cash and Cash Equivalents We consider all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. We may maintain cash and cash equivalents in financial institutions in excess of insured limits. In an effort to mitigate this risk, we only invest in or through major financial institutions. Restricted Cash Restricted cash consists primarily of impound reserve accounts for property taxes, insurance and capital improvements in connection with the requirements of certain of our loan agreements. Real Estate Purchase Price Allocation and Treatment of Acquisition Costs We account for asset acquisitions in accordance with GAAP which requires that we allocate the purchase price of a property to the tangible and intangible assets acquired and the liabilities assumed based on their relative fair values as of the date of acquisition. This guidance requires us to make significant estimates and assumptions, including fair value estimates, which requires the use of significant unobservable inputs as of the acquisition date. We engage third-party valuation specialists to assist in the determination of significant estimates and market-based assumptions used in the valuation models. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month in-place, in-place Allocation of purchase price to acquisitions of portfolios of facilities are allocated to the individual facilities based upon an income approach or a cash flow analysis using appropriate risk adjusted capitalization rates which take into account the relative size, age, and location of the individual facility along with current and projected occupancy and rental rate levels or appraised values, if available. Acquisitions that do not meet the definition of a business, as defined under current GAAP, are accounted for as asset acquisitions. During the years ended December 31, 2023, 2022, and 2021, our property acquisitions, including the SST IV Merger and the SSGT II Merger, did not meet the definition of a business because substantially all of the fair value was concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) and because the acquisitions did not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. As a result, once an acquisition is deemed probable, acquisition related transaction costs are capitalized rather than expensed. During the years ended December 31, 2023, 2022, and 2021 we expensed approximately $0.2 million, $0.9 million, and $0.9 million, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods. Evaluation of Possible Impairment of Real Property Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our real property assets may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the real property assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the real property assets to the fair value and recognize an impairment loss. For the years ended December 31, 2023, 2022, and 2021, no real property asset impairment losses were recognized. Goodwill Valuation We initially recorded goodwill as a result of the Self Administration Transaction (as defined in Note 10 – Related Party Transactions), which occurred in 2019. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable, and is not amortized. We perform an annual qualitative impairment assessment as of December 31 for goodwill; between annual tests we evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. If circumstances indicate the carrying amount may not be fully recoverable, we perform a quantitative analysis to compare the fair value of each reporting unit to its respective carrying amount. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized. See Note 10 – Related Party Transactions for additional information. Trademarks In connection with the Self Administration Transaction, we recorded the fair value associated with the two primary trademarks acquired therein. Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible fair value of our ownership of the brand name. As of December 31, 2023 and December 31, 2022, $15.7 million was recorded related to the SmartStop ® ® ” ® We qualitatively evaluate whether any triggering events or changes in circumstances have occurred in addition to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuation methods is adversely impacted, the impact could result in a material impairment charge in the future. Revenue Recognition Self Storage Operations Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. In accordance with ASC 842, we review the collectability of lease payments on an ongoing basis. We consider collectability indicators when analyzing accounts receivable and historical bad debt levels, including current economic trends, all of which assist in evaluating the probability of outstanding and future rental income collections. Additionally, we earn ancillary revenue by selling tenant insurance or tenant protection plans to customers at our properties through our Tenant Protection Programs, and to a lesser extent, through the sale of various moving and packing supplies such as locks and boxes. We recognize such revenue in the Ancillary operating revenue line within our consolidated statements of operations as the services are performed and as the goods are delivered. Managed REIT Platform We earn property management and asset management revenue, pursuant to the respective property management and advisory agreement contracts, in connection with providing services to the Managed REITs. We have determined under ASC 606 – Revenue from Contracts with Customers (“ASC 606”), that the performance obligation for the property management services and asset management services are satisfied as the services are rendered. While we are compensated for our services on a monthly basis, these services represent a series of distinct daily services in accordance with ASC 606. Such revenue is recorded in the Managed REIT Platform revenue line within our consolidated statements of operations. The Managed REITs’ advisory agreements also provide for reimbursement to us of our direct and indirect costs of providing administrative and management services to the Managed REITs. These reimbursements include costs incurred in relation to organization and offering services provided to the Managed REITs and the reimbursement of salaries, bonuses, and other expenses related to benefits paid to our employees while performing services for the Managed REITs. The Managed REITs’ property management agreements also provide reimbursement to us for the property manager’s costs of managing the properties. Reimbursable costs include wages and salaries and other expenses that arise in operating, managing and maintaining the Managed REITs’ properties. Under ASC 606, direct reimbursement of such costs does not represent a separate performance obligation from our obligation to perform property management and asset management services. The reimbursement income is considered variable consideration, and is recognized as the costs are incurred, subject to limitations on the Managed REIT Platform’s ability to incur offering costs or limitations imposed by the advisory agreements. We have elected to separately record such revenue in the Reimbursable costs from Managed REITs line within our consolidated statements of operations. Additionally, we earn revenue in connection with our Tenant Protection Programs joint ventures with our Managed REITs. We also earn development and construction management revenue from services we provide in connection with the project design, coordination and oversite of development and certain capital improvement projects undertaken by the Managed REITs. We recognize such revenue in the Managed REIT Platform revenue line within our consolidated statements of operations as the services are performed or delivered. See Note 10 – Related Party Transactions, for additional information regarding revenue generated from our Managed REIT Platform. Sponsor Funding Agreement On November 1, 2023, SmartStop REIT Advisors, LLC, a subsidiary of SmartStop OP entered into a sponsor funding agreement with SST VI and SST VI OP (the “Sponsor Funding Agreement”), in connection with certain changes to the public offering of SST VI (see Note 10 - Related Party for additional information). Pursuant to the Sponsor Funding Agreement, SmartStop, through a wholly-owned subsidiary, is required to fund the payment of the front-end sales load for the sale of SST VI’s class Y and class Z shares sold in their offering. In exchange, SmartStop receives a number of series C convertible units (“Series C Units”) in SST VI’s operating partnership calculated as the dollar amount of such funding divided by the then-current offering price for such class Y and Z shares. The Series C Units convert into class A units of SST VI OP if the estimated net asset value of SST VI, as declared by SST VI, exceeds $10.00 per share. Such conversion is limited such that the dilution caused by the conversion may not reduce the diluted estimated net asset value below $10.00 per share. In accordance with ASC 606, the amount by which our funding exceeds the fair value of the Series C Units received is accounted for as a payment to a customer and is therefore recorded as a reduction to the transaction price for the services we provide to such customer. Each payment is initially included in the Other assets line-item in our consolidated balance sheet and subsequently recorded as a reduction of Managed REIT Platform revenues ratably over the remaining estimated life of our management contracts with SST VI. Below is a summary of the portion of sponsorship funding payments which exceeds the fair value of the Series C Units received, and is recorded pursuant to ASC 606 as described above: Balance as of December 31, 2022 $ —  Amounts incurred 3,526,927 Recorded sponsor funding reduction (33,643 ) Balance as of December 31, 2023 $ 3,493,284 Allowance for Doubtful Accounts Tenant accounts receivable is reported net of an allowance for doubtful accounts. Management records this general allowance estimate based upon a review of the current status of accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future. As of December 31, 2023 and 2022, approximately $0.9 million and $0.7 million, respectively, were recorded to allowance for doubtful accounts, and are included within other assets in the accompanying consolidated balance sheets. Advertising Costs Advertising costs are expensed in the period in which the cost is incurred and are included in property operating expenses and general and administrative lines within our consolidated statements of operations, depending on the nature of the expense. We incurred advertising costs of approximately $2.2 million, $1.3 million, and $0.7 million for the years ended December 31, 2023, 2022, and 2021, respectively, within general and administrative. We incurred advertising costs of approximately $4.8 million, $4.4 million, and $3.7 million for the years ended December 31, 2023, 2022, and 2021, respectively, within property operating expenses. Real Estate Facilities We capitalize costs incurred to develop, construct, renovate and improve properties, including interest and property taxes incurred during the construction period. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use. Depreciation of Real Property Assets Our management is required to make subjective assessments as to the useful lives of our depreciable assets. We consider the period of future benefit of the asset to determine the appropriate useful lives. Depreciation of our real property assets is charged to expense on a straight-line basis over the estimated useful lives as follows: Description Standard Depreciable Life Land Not Depreciated Buildings 30-40 years Site Improvements 7-10 Depreciation of Personal Property Assets Personal property assets consist primarily of furniture, fixtures and equipment and are depreciated on a straight-line basis over the estimated useful lives, generally ranging from 3 to 5 years, and are included in other assets on our consolidated balance sheets. Intangible Assets We have allocated a portion of our real estate purchase price to in-place The total estimated future amortization expense related to intangible assets for the years ending December 31, 2024, 2025, 2026, 2027, 2028, and thereafter is approximately $0.2 million, $0.1 million, $0.1 million, $0.1 million, $0.1 million, and $0.6 million thereafter, respectively. The weighted-average amortization period on our remaining intangible assets with a net book value of approximately $1.2 million was approximately 5.8 years as of December 31, 2023. We evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuations methods is adversely impacted, the impact could result in an impairment charge in the future. Debt Issuance Costs Costs incurred in connection with obtaining non revolving debt are presented on the balance sheet as a deduction from debt; amounts incurred related to obtaining revolving debt are included in the debt issuance costs line on our consolidated balance sheet (see Note 5 – Debt). Debt issuance costs are amortized using the effective interest method. As of December 31, 2023, the gross amount of debt issuance costs related to our revolving credit facility totaled approximately $4.5 million and accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $4.1 million. As of December 31, 2022, the gross amount of debt issuance costs related to our revolving credit facility totaled approximately $4.5 million, and accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $2.4 million. As of December 31, 2023, the gross amount allocated to debt issuance costs related to non-revolving debt totaled approximately $7.7 million and accumulated amortization of debt issuance costs related to non-revolving debt totaled approximately $3.4 million. As of December 31, 2022, the gross amount allocated to debt issuance costs related to non-revolving non-revolving Organizational and Offering Costs Through March 31, 2022, we paid our Former Dealer Manager an ongoing stockholder servicing fee that was payable monthly and accrued daily in an amount equal to 1/365th of 1% of the purchase price per share of the Class T Shares sold in the Primary Offering. In accordance with the selling agreements we entered into with respect to the sale of Class T Shares, we ceased paying the stockholder servicing fee with respect to the Class T Shares sold in the Primary Offering on the fifth anniversary of the last day of the fiscal quarter in which our Primary Offering (i.e., excluding our distribution reinvestment plan offering) terminated (March 31, 2022). Our Former Dealer Manager entered into participating dealer agreements with certain other broker-dealers which authorized them to sell our shares. Upon sale of our shares by such broker-dealers, our Former Dealer Manager re-allowed re-allow Foreign Currency Translation For non-U.S. Redeemable Common Stock We adopted a share redemption program (“SRP”) that enables stockholders to sell their shares to us in limited circumstances. We have evaluated the terms of our SRP, and we classify amounts that are redeemable under the SRP as redeemable common stock in the accompanying consolidated balance sheets. The maximum amount of redeemable shares under our SRP is limited to the net proceeds from the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation of us to repurchase shares be classified as liabilities and reported at settlement value. When we determine we have a mandatory obligation to repurchase shares under the SRP, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. See Note 12 – Commitments and Contingencies for additional information on our SRP. Accounting for Equity Awards We issue equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”), both of which may be issued subject to either time based vesting criteria or performance based vesting criteria restrictions. For time based awards granted which contain a graded vesting schedule, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For performance based awards, compensation cost is recognized over the requisite service period if and when we determine the performance condition is probable of being achieved. We record the cost of such equity based awards based on the grant date fair value, and have elected to record forfeitures as they occur. Employee Benefit Plan The Company terminated its relationship with a professional employer organization and began maintaining its own retirement savings plan during the year ended December 31, 2021 under Section 401(k) of the Internal Revenue Code under which eligible employees can contribute up to 100% of their annual salary, subject to a statutory prescribed annual limit. For the year ended December 31, 2023 and 2022, the Company made matching contributions to such plan of approximately $0.5 million and $0.5 million, respectively, based on a company match of 100% on the first 4% of an employee’s compensation. Fair Value Measurements Under GAAP, we are required to measure certain financial instruments at fair value on a recurring basis. In addition, we are required to measure other financial instruments and balances at fair value on a non-recurring • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; • Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and • Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety. The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we will utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment will be necessary to interpret Level 2 and 3 inputs in determining fair value of our financial and non-financial Financial and non-financial non-recurring along with the assets and liabilities described in Note 3 – Real Estate Facilities. The fair values of these assets and liabilities were determined as of the acquisition dates using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) market approach, which considers comparable sales activity. Additionally, certain such assets and liabilities are required to be fair valued periodically or valued pursuant to ongoing fair value requirements and impairment analyses and have been valued subsequently utilizing the same techniques noted above. In general, we consider multiple valuation techniques when measuring fair values. However, in certain circumstances, a single valuation technique may be appropriate. All of the fair values of the assets and liabilities as of the acquisition dates were derived using Level 3 inputs. The Series C Units (categorized within Level 3 of the fair value hierarchy) acquired in connection with the Sponsor Funding Agreement are measured at fair value at the time of acquisition, and are recorded using the equity method of accounting as described in Note 10 - Related Parties. The fair value of these units were determined using a valuation model which considered the following key assumptions: the projected distribution rate of SST VI, implied share price volatility, risk free interest rate, and the estimated effective life of the Series C Units. The carrying amounts of cash and cash equivalents, restricted cash, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates approximate fair value (categorized within Level 1 of the fair value hierarchy).

Real Estate [Abstract]
Real Estate	Note 3. Real Estate The following summarizes the activity in real estate during the nine months ended September 30, 2024 (in thousands): Real estate Balance at December 31, 2023 $ 1,924,746 Impact of foreign exchange rate changes and other (4,602 ) Improvements and additions 7,514 Casualty loss (1) (6,541 ) Acquisitions 53,080 Balance at September 30, 2024 $ 1,974,197 Accumulated depreciation Balance at December 31, 2023 $ (255,844 ) Casualty loss (1) 1,913 Depreciation expense (40,189 ) Impact of foreign exchange rate changes and other 602 Balance at September 30, 2024 $ (293,518 ) (1) Hurricane Helene caused record flooding in late September 2024 in Asheville, North Carolina. One of our 14 wholly-owned properties in this market was severely flooded. As a result of the storm event, flooding and related damage, we recorded a net casualty loss related to this property of approximately $4.6 million during the three and nine months ended September 30, 2024, to write-off the carrying value. We expect to rebuild and therefore we believe it is probable that we will receive insurance proceeds to offset the casualty loss and have recorded a receivable related to our pending insurance claims. Consequently the casualty loss was completely offset in our consolidated statements of operations by such recovery. Any amount of insurance recovery related to the property damage in excess of the casualty loss incurred is considered a gain contingency, and will be recognized upon final settlement of the claims. SSGT II Merger On June 1, 2022, we closed on our merger with SSGT II (the “SSGT II Merger”). On such date, (the “SSGT II Merger Date”), we acquired all of the real estate owned by SSGT II, consisting primarily of (i) 10 wholly-owned self storage facilities, and (ii) SSGT II’s 50% equity interest in three unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada. We issued approximately 11.5 million Class A Shares to the former SSGT II stockholders in connection with the SSGT II Merger. SST IV Merger On March 17, 2021, we closed on our merger with SST IV (the “SST IV Merger”). On such date, (the “SST IV Merger Date”), we acquired all of the real estate owned by SST IV, consisting primarily of (i) 24 self storage facilities, and (ii) SST IV’s 50% equity interest in six unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada. As a result of the SST IV Merger, we issued approximately 23.1 million Class A Shares to the former SST IV stockholders. Self Storage Facility Acquisitions On April 10, 2024, we purchased a self storage facility located in Colorado Springs, Colorado (the “Colorado Springs II Property”). The purchase price for the Colorado Springs II Property was approximately $10.5 million, plus closing costs. Upon acquisition, the property was approximately 86% occupied. On July 16, 2024, we purchased a self storage facility located in Spartanburg, South Carolina (the “Spartanburg Property”). The purchase price for the Spartanburg Property was approximately $13.2 million, plus closing costs. Upon acquisition, the property was approximately 94% occupied. On September 24, 2024, we purchased a self storage facility located in Miami, Florida (the “Miami Property”). The purchase price for the Miami Property was approximately $31.2 million, plus closing costs. Upon acquisition, the property was approximately 96% occupied. The following table summarizes our purchase price allocation for our acquisitions during the nine months ended September 30, 2024 (in thousands): Acquisition Acquisition Date Real Estate Intangibles Total (1) 2024 (2) 2024 Net Operating Income (2)(3) Colorado Springs II 4/10/2024 $ 9,841 $ 675 $ 10,516 $ 446 $ 266 Spartanburg 7/16/2024 12,831 401 13,232 229 124 Miami 9/24/2024 30,408 753 31,161 25 3 $ 53,080 $ 1,829 $ 54,909 $ 700 $ 393 (1) The allocation noted above is based on a determination of the relative fair value of the total consideration provided and represents the amount paid including capitalized acquisition costs. (2) The operating results of the self storage properties acquired have been included in our consolidated statements of operations since their acquisition dates. (3) Net operating income excludes corporate general and administrative expenses, interest expense, depreciation, amortization and acquisition related expenses. Potential Acquisitions As of November 13, 2024, we, through our wholly-owned subsidiaries were party to four purchase and sale agreements with unaffiliated third parties for the acquisition of self storage facilities located in the United States and Canada. The total purchase price for these properties is approximately $83.3 million, plus closing costs. There can be no assurance that we will complete these acquisitions. If we fail to acquire these properties, in addition to the incurred acquisition costs, we may also forfeit earnest money of approximately $1.2 million as a result. We may assign some or all of the above purchase and sale agreements to one or more of our Managed REITs.	Note 3. Real Estate Facilities The following summarizes the activity in real estate facilities during the years ended December 31, 2023 and 2022: Real estate facilities Balance at December 31, 2021 $ 1,593,623,628 Facilities acquired through merger with SSGT II 228,359,718 Other facility acquisitions 69,981,850 Impact of foreign exchange rate changes (12,984,154 ) Improvements and additions 8,224,603 Balance at December 31, 2022 1,887,205,645 Acquisitions 23,696,536 Impact of foreign exchange rate changes and other 4,342,673 Improvements and additions 9,501,518 Balance at December 31, 2023 $ 1,924,746,372 Accumulated depreciation Balance at December 31, 2021 $ (155,926,875 ) Depreciation expense (48,400,073 ) Impact of foreign exchange rate changes 1,644,260 Balance at December 31, 2022 (202,682,688 ) Depreciation expense (52,619,881 ) Impact of foreign exchange rate changes and other (541,715 ) Balance at December 31, 2023 $ (255,844,284 ) SSGT II Merger On June 1, 2022, we closed on our merger with SSGT II (the “SSGT II Merger”). On such date, (the “SSGT II Merger Date”), each share of SSGT II’s common stock, $0.001 par value per share (“SSGT II Common Stock”), issued and outstanding immediately prior to the effective time of the SSGT II Merger (other than shares owned by us, any subsidiary of ours, or any subsidiary of SSGT II) was automatically converted into the right to receive 0.9118 shares of our Class A Shares, subject to the treatment of fractional shares in accordance with the SSGT II merger agreement (the “SSGT II Merger Consideration”). As a result, we acquired all of the real estate owned by SSGT II, consisting of (i) 10 wholly-owned self storage facilities located in seven states comprising approximately 7,740 self storage units and approximately 853,900 net rentable square feet, and (ii) SSGT II’s 50% equity interest in three unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada. As of the SSGT II Merger Date, the unconsolidated real estate ventures (collectively, the “SSGT II JV Properties”) consisted of one operating self storage property and two parcels of land being developed into self storage facilities, with subsidiaries of SmartCentres Real Estate Investment Trust, an unaffiliated third party (“SmartCentres”) owning the other 50% of such entities. Additionally, we obtained SSGT II’s rights to acquire (i) one parcel of land being developed into a self storage facility in an unconsolidated joint venture with SmartCentres, and (ii) a self storage property under development located in Southern California, which we acquired on July 13, 2023. On January 12, 2023, we acquired the aforementioned parcel of land in an unconsolidated joint venture that we and SmartCentres intend to develop into a self storage facility in the future. As of December 31, 2023, one of the development joint venture properties had been completed and had begun operations. The following table reconciles the total consideration transferred in the SSGT II Merger: Fair value of consideration: Common stock issued $ 168,791,577 Cash (1) 76,300,006 Preexisting investments in and advances to SSGT II (2) 16,066,930 Total consideration $ 261,158,513 (1) The approximately $76.3 million in cash was primarily used to pay off approximately $75.1 million of SSGT II’s debt that we did not assume in the SSGT II Merger, as well as approximately $1.2 million in transaction costs. (2) Upon our acquisition of SSGT II, we recorded a gain of approximately $16.1 million to record the then fair market value of our special limited partnership interest in SSGT II operating partnership. We issued approximately 11.5 million Class A Shares to the former SSGT II stockholders in connection with the SSGT II Merger. The estimated fair value of our common stock issued was determined by third party valuation specialists primarily based on an income approach to value our properties as well as our Managed REIT Platform, adjusted for market related adjustments and illiquidity discounts, less the estimated fair value of our debt and other liabilities. These fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement as discussed in Note 2 – Summary of Significant Accounting Policies. The key assumptions used in estimating the fair value of our common stock included a marketability discount of 6%, projected annual net operating income, land sales comparisons, growth rates, discount rates, and capitalization rates. The following table summarizes the relative fair values of the assets acquired and liabilities assumed in the SSGT II Merger: Assets Acquired: Land $ 21,111,616 Buildings 201,026,974 Site improvements 6,221,128 Construction in process 252,925 Intangible assets (1) 15,688,002 Investments in real estate joint ventures 7,394,539 Cash and cash equivalents, and restricted cash 10,759,283 Other assets 847,359 Total assets acquired $ 263,301,826 Liabilities assumed: Total liabilities assumed (2) $ 2,143,313 Total net assets acquired $ 261,158,513 (1) Approximately $8.0 million of the intangible assets acquired related to the intrinsic value of a purchase and sale agreement for the acquisition of a property in San Gabriel, CA that we assumed in the SSGT II Merger and acquired on July 13, 2023. The remainder of the intangible asset relates to value ascribed to the in-place (2) Liabilities assumed represents accounts payable and other liabilities. As a result of our acquiring SSGT II and terminating the preexisting advisory and property management agreements with SSGT II, we expensed approximately $2.0 million related to such assets on the acquisition date. SST IV Merger On March 17, 2021, we closed on our merger with SST IV (the “SST IV Merger”). On such date, (the “SST IV Merger Date”), we acquired all of the real estate owned by SST IV, consisting of (i) 24 self storage facilities located in nine states comprising approximately 18,000 self storage units and approximately 2.0 million net rentable square feet, and (ii) SST IV’s 50% equity interest in six unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada (collectively the “SST IV JV Properties”). The SST IV JV Properties consisted of three operating self storage properties and three parcels of land in various stages of development into self storage facilities as of the SST IV Merger Date, jointly owned with subsidiaries of SmartCentres. The three development joint venture properties have subsequently been completed and have begun operations. The following table reconciles the total consideration transferred in the SST IV Merger: Fair Value of Consideration Transferred: Common stock issued $ 231,412,470 Cash (1) 54,250,000 Other 365,703 Total Consideration Transferred $ 286,028,173 (1) The approximately $54.3 million in cash was primarily used to pay off approximately $54.0 million of SST IV debt that we did not assume in the SST IV Merger, as well as approximately $0.3 million in transaction costs. As a result of the SST IV Merger, approximately 23.1 million Class A Shares were issued in exchange for approximately 10.6 million shares of SST IV common stock. The estimated fair value of our common stock issued was determined by third party valuation specialists primarily based on an income approach to value the properties as well as our Managed REIT Platform, adjusted for market related adjustments and illiquidity discounts, less the estimated fair value of our debt and other liabilities. These fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement as discussed in Note 2 – Summary of Significant Accounting Policies. The key assumptions used in estimating the fair value of our common stock included a marketability discount of 6%, projected annual net operating income, land sales comparisons, growth rates, discount rates, and capitalization rates.

Self Storage Facility Acquisitions In connection with the SSGT II Merger, we recorded an intangible asset of approximately $8.0 million related to the intrinsic value of a purchase and sale agreement for the San Gabriel Property which was being developed by the seller into a self storage facility. On July 5, 2023, we entered into an approximately $10.4 million first mortgage bridge loan to the seller, and on July 13, 2023, we closed on the San Gabriel Property and the seller repaid the bridge loan in full. We recorded approximately $23.7 million to Real estate facilities related to the San Gabriel Property, which consisted of the contractual purchase price of approximately $15.5 million, as well as approximately $8.0 million which was previously recorded as an intangible asset. The following table summarizes the purchase price allocation for the real estate related assets acquired during the year ended December 31, 2023: Acquisition Acquisition Real Estate Intangibles Total (1) 2023 (2) 2023 Net Operating (2)(3) San Gabriel Property 7/13/2023 $ 23,696,536 $ —  $ 23,696,536 $ 22,964 $ (157,676 ) $ 23,696,536 $ —  $ 23,696,536 $ 22,964 $ (157,676 ) (1) The allocation noted above is based on a determination of the relative fair value of the total consideration provided and represents the amount paid including capitalized acquisition costs.

Potential Acquisitions We, through our wholly-owned subsidiaries were party to a purchase and sale agreement with an unaffiliated third party for the acquisition of a self storage facility located in the U.S. which had not yet closed as of December 31, 2023. The total purchase price for this property was approximately $10.5 million, plus closing costs. There can be no assurance that we will complete this acquisition. If we fail to acquire this property, in addition to the incurred acquisition costs, we may also forfeit earnest money of approximately $0.2 million as a result. We may assign the above purchase and sale agreement to one of our Managed REITs.

Investments in Unconsolidated Real Estate Ventures	Note 4. Investments in Unconsolidated Real Estate Ventures Nantucket Joint Venture On July 18, 2024, we entered into a joint venture arrangement with an unaffiliated third party to develop a self storage property in Nantucket, Massachusetts (the “Nantucket Joint Venture”). On such date we agreed to purchase a minority ownership in the property of approximately 38%, and immediately funded approximately $4.9 million. In September 2024, we funded an additional $1.3 million. Upon completion of development, we expect to serve as property manager of the self storage property. This investment is accounted for pursuant to the equity method of accounting as we have the ability to exercise influence, but not control. As of September 30, 2024, the carrying value of this investment was approximately $6.2 million. SmartCentres Joint Ventures As a result of the SST IV Merger, we acquired six self storage real estate joint ventures located in the Greater Toronto Area of Ontario, Canada, all of which were operating as of September 30, 2024. As a result of the SSGT II Merger, we acquired three self storage real estate joint ventures located in the Greater Toronto Area of Ontario, Canada, all of which were operating as of September 30, 2024. On May 25, 2022, we, as 50% owner and SmartCentres as the other 50% owner of a joint venture subsidiary, purchased a single tenant industrial building located in the city of Burnaby, British Columbia (the “Regent Property”), that we and SmartCentres intend to develop into a self storage facility in the future. On January 12, 2023, we as 50% owner and SmartCentres as the other 50% owner of a joint venture subsidiary, purchased a parcel of land in Whitby, Ontario, (the “Whitby Property”), that we and SmartCentres developed into a self storage facility that became operational in January 2024. These joint venture agreements are with a subsidiary of SmartCentres, an unaffiliated third party, to acquire, develop, and operate self storage facilities. For the three months ended September 30, 2024 and 2023, we recorded net aggregate loss of approximately $0.4 million and $0.3 million respectively, from our equity in earnings related to our unconsolidated real estate ventures in Canada. For the nine months ended September 30, 2024 and 2023, we recorded net aggregate loss of approximately $1.1 million and $1.2 million respectively, from our equity in earnings related to our unconsolidated real estate ventures in Canada.

(2) These joint venture properties were acquired through the SST IV Merger, which closed on March 17, 2021. (3) This property was leased as a single tenant industrial lease as of September 30, 2024. The joint venture plans to develop this property into a self storage facility in the future. (4) This property was acquired on January 12, 2023 in connection with a purchase agreement assumed in the SSGT II Merger. (5) As of September 30, 2024, these properties were encumbered by first mortgages pursuant to the RBC JV Term Loan II (defined below). (6) As of September 30, 2024, these properties were encumbered by first mortgages pursuant to the RBC JV Term Loan (defined below). (7) This property is encumbered by a first mortgage pursuant to the SmartCentres Financings (defined below). RBC JV Term Loan II On July 17, 2024, three of our joint ventures with SmartCentres closed on a $46.0 million CAD term loan (the “RBC JV Term Loan II”) with Royal Bank Canada (“RBC”) pursuant to which three of our joint venture subsidiaries that each own 50% of a JV Property serve as borrowers (the “RBC Borrowers II”). The RBC JV Term Loan II is secured by first mortgages on three of the JV Properties which were previously encumbered by the SmartCentres Financings. The maturity date of the RBC JV Term Loan II is November 3, 2025, which may be requested to be extended by one additional year at the sole discretion of RBC and subject to certain conditions. Interest on the RBC JV Term Loan is a fixed annual rate of 4.97%, and payments are interest only during the term of the loan. We and SmartCentres each serve as a full recourse guarantor with respect to 50% of the secured obligations under the RBC JV Term Loan II. The RBC JV Term Loan II contains certain customary representations and warranties, affirmative, negative and financial covenants, and events of default. Pursuant to the terms of the RBC JV Term Loan II, a failure by either us or SmartCentres to observe any negative covenant under each of our respective (and separate) credit facilities (“Separate Credit Facilities”) would be an event of default under the RBC JV Term Loan II. We and SmartCentres entered into a separate Cross-Indemnity Agreement pursuant to which we and SmartCentres have each agreed to indemnify the other party with respect to any claims arising from a breach or default of the other party pursuant to the RBC JV Term Loan II or the Separate Credit Facilities. The net proceeds from the RBC JV Term Loan II, in combination with cash on hand were used to fully repay the allocated loan amounts of approximately $46.4 million CAD or approximately $34.1 million USD under the SmartCentres Financings for each of the three JV Properties. As of September 30, 2024, there was approximately $46.0 million CAD or approximately $34.0 million USD outstanding on the RBC JV Term Loan II. RBC JV Term Loan On November 3, 2023, five of our joint ventures with SmartCentres closed on a $70 million CAD term loan (the “RBC JV Term Loan”) with RBC pursuant to which five of our joint venture subsidiaries that each own 50% of a Joint Venture property serve as borrowers (the “RBC Borrowers”). The RBC JV Term Loan is secured by first mortgages on five of the JV Properties which were previously encumbered by the SmartCentres Financings (as defined below). The maturity date of the RBC JV Term Loan is November 2, 2025, which may be requested to be extended by one additional year by the RBC Borrowers, subject to the approval of RBC in its sole and absolute discretion. Interest on the RBC JV Term Loan is a fixed annual rate of 6.21%, and payments are interest only during the term of the loan. We and SmartCentres each serve as a full recourse guarantor with respect to 50% of the secured obligations under the RBC JV Term Loan. The RBC JV Term Loan contains certain customary representations and warranties, affirmative, negative and financial covenants, and events of default. Pursuant to the terms of the RBC JV Term Loan, a failure by either us or SmartCentres to observe any negative covenant under each of our Separate Credit Facilities would be an event of default under the RBC JV Term Loan; in addition, certain actions by either us or SmartCentres may trigger an event of default under the RBC JV Term Loan. We and SmartCentres entered into a separate Cross-Indemnity Agreement pursuant to which we and SmartCentres have each agreed to indemnify the other party with respect to any claims arising from a breach or default of the other party pursuant to the RBC JV Term Loan or the Separate Credit Facilities. The majority of net proceeds from the RBC JV Term Loan were used to fully repay the allocated loan amounts of approximately $68.9 million CAD under the SmartCentres Financings (as defined below) for each of the five JV Properties. As of September 30, 2024, $70.0 million CAD or approximately $51.8 million in USD, was outstanding on the RBC JV Term Loan. SmartCentres Financings In connection with the SST IV Merger, we, through our acquisition of the Oshawa, East York, Brampton, Vaughan, and Scarborough joint venture partnerships, also became party to a master mortgage commitment agreement (the “MMCA I”) with SmartCentres Storage Finance LP (the “SmartCentres Lender”) (the “SmartCentres Loan I”). The SmartCentres Lender is an affiliate of SmartCentres. On August 18, 2021, the Kingspoint Property was added to the MMCA I, increasing the available capacity. On June 1, 2022, in connection with the SSGT II Merger, we assumed another loan with the SmartCentres Lender. SSGT II had previously entered into a master mortgage commitment agreement on April 30, 2021, which was subsequently modified on October 22, 2021 (the “MMCA II”), with the SmartCentres Lender in the amount of up to approximately $34.3 million CAD (the “SmartCentres Loan II”) (collectively with SmartCentres Loan I, the “SmartCentres Financings”). The borrowers under the SmartCentres Loan II are the joint venture entities in which we (SSGT II prior to June 1, 2022), and SmartCentres each hold a 50% limited partnership interest with respect to the Dupont and Aurora joint venture properties. In connection with the SmartCentres Loan II assumption, we became a recourse guarantor for 50% of the SmartCentres Financings. On September 13, 2022, the Markham Property was added to the MMCA II, increasing the available capacity. The SmartCentres Loan I and SmartCentres Loan II have an accordion feature such that borrowings pursuant thereto may be increased up to approximately $120 million CAD each, subject to certain conditions set forth in the MMCA I and MMCA II agreements. Additionally, pursuant to the MMCA I and MMCA II agreements, the collective borrowings between all SmartCentres Financings, and loans made by the SmartCentres Lender to our affiliates, are limited to an overall combined capacity of $120 million CAD. The SmartCentres Financings were amended on May 13, 2024, extending the maturity date to May 11, 2026, among other changes. Monthly interest payments initially increase the outstanding principal balance. Upon a JV Property generating sufficient net cash flow, the SmartCentres Financings provide for the commencement of quarterly payments of interest. The borrowings advanced pursuant to the SmartCentres Financings may be prepaid without penalty, subject to certain conditions set forth in the MMCA I and MMCA II. The SmartCentres Financings contain customary affirmative and negative covenants, agreements, representations, warranties and borrowing conditions (including a loan to value ratio of no greater than 70% with respect to each JV Property) and events of default, all as set forth in the MMCA I and MMCA II. We serve as a full recourse guarantor with respect to 50% of the SmartCentres Financings. As of September 30, 2024, the joint ventures were in compliance with all such covenants. On July 17, 2024, three of our joint ventures with SmartCentres closed on a $46.0 million CAD term loan with RBC pursuant to which three of our joint venture subsidiaries that each own 50% of a JV Property serve as borrowers. The RBC JV Term Loan II is secured by first mortgages on three of the JV Properties which were previously encumbered by the SmartCentres Financings. The net proceeds from such loan were used to fully repay the allocated loan amounts of approximately $46.4 million CAD or approximately $34.1 million USD under the SmartCentres Financings for each of the three JV Properties. Interest on the SmartCentres Financings is a variable annual rate equal to the aggregate of: (i) the BA Equivalent Rate, plus: (ii) a margin based on the External Credit Rating, plus (iii) a margin under the Senior Credit Facility, each as defined and described further in the MMCA I and MMCA II. As of September 30, 2024, the total interest rate was approximately 7.3%. As of September 30, 2024, approximately $17.3 million CAD or approximately $12.8 million in USD, was outstanding on the SmartCentres Financings. As of December 31, 2023, approximately $57.3 million CAD or approximately $43.3 million USD was outstanding on the SmartCentres Financings. The proceeds of the SmartCentres Financings have been and will generally be used to finance the acquisition, development, and construction of the JV Properties.	Note 4. Investments in Unconsolidated Real Estate Ventures As a result of the SST IV Merger, we acquired six self storage real estate joint ventures located in the Greater Toronto Area of Ontario, Canada, all of which were operating properties as of December 31, 2023. As a result of the SSGT II Merger, we acquired three self storage real estate joint ventures located in the Greater Toronto Area of Ontario, Canada, two of which were operating properties and one of which was under development as of December 31, 2023. On May 25, 2022, we, as 50% owner and SmartCentres as the other 50% owner of a joint venture subsidiary, purchased a single tenant industrial building located in the city of Burnaby, British Columbia (the “Regent Property”), that we and SmartCentres intend to develop into a self storage facility in the future. Our 50% of the total purchase price for the Regent Property was approximately $3.5 million CAD (or approximately $2.7 million USD), plus closing costs. On January 12, 2023, we as 50% owner and SmartCentres as the other 50% owner of a joint venture subsidiary, purchased a parcel of land in Whitby, Ontario, (the “Whitby Property”), that we and SmartCentres are developing into a self storage facility in the future. Our 50% of the initial investment at closing for the Whitby Property was approximately $2.7 million CAD (or approximately $2.0 million USD), plus closing costs. These joint venture agreements are with a subsidiary of SmartCentres, an unaffiliated third party, to acquire, develop, and operate self storage facilities. We account for these investments using the equity method of accounting and they are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and increased for contributions. Equity in earnings (loss) will generally be recognized based on our ownership interest in the earnings (loss) of each of the unconsolidated investments, and is recorded in Equity in earnings (losses) from investments in JV Properties in the accompanying consolidated statements of operations. For the years ended December 31, 2023 and 2022, we recorded net aggregate loss of approximately $1.6 million and $0.8 million respectively, from our equity in earnings related to our unconsolidated real estate ventures in Canada.

The joint venture plans to develop this property into a self storage facility in the future. (4) This property was acquired on January 12, 2023 in connection with a purchase agreement assumed in the SSGT II Merger. Potential Future Joint Ventures We as 50% owner and SmartCentres as the other 50% owner of a joint venture subsidiary were party to two purchase and sale agreements for the acquisition of land in Canada intended to be developed into self storage facilities which had not yet closed. Our 50% portion of the total purchase price for these properties was approximately USD $7.6 million, plus closing costs. There can be no assurance that we will complete these acquisitions. Additionally, we may assign some or all of such purchase and sale agreements to the Managed REITs. If we fail to acquire these properties, in addition to the incurred acquisition costs, we may also forfeit earnest money of approximately USD $1.1 million as a result. RBC JV Term Loan On November 3, 2023, we closed on a $70 million CAD term loan (the “RBC JV Term Loan”) with Royal Bank of Canada (“RBC”) pursuant to which five of our joint venture subsidiaries that each own 50% of a Joint Venture property serve as borrowers (the “RBC Borrowers”). The RBC JV Term Loan is secured by first mortgages on five of the JV Properties which were previously encumbered by the SmartCentres Financings (as defined below). The maturity date of the RBC JV Term Loan is November 2, 2025, which may be requested to be extended by one additional year by the RBC Borrowers, subject to the approval of RBC in its sole and absolute discretion. Interest on the RBC JV Term Loan is a fixed annual rate of 6.21%, and payments are interest only during the term of the loan.

The separate assets of these encumbered properties are not available to pay our other debts. (2) This fixed rate loan encumbers five properties (Pompano Beach, Lake Worth, Jupiter, Royal Palm Beach, and Delray) with monthly interest only payments until June 2022, at which time both interest and principal payments became due monthly. The separate assets of these encumbered properties are not available to pay our other debts. (3) This fixed rate, interest only loan encumbers 10 properties (Myrtle Beach I, Myrtle Beach II, Port St. Lucie, Plantation, Sonoma, Las Vegas I, Las Vegas II, Las Vegas III, Ft Pierce, and Nantucket Island). The separate assets of these encumbered properties are not available to pay our other debts. (4) On March 17, 2021, in connection with the SST IV Merger, we assumed a $40.5 million fixed rate CMBS financing with KeyBank as the initial lender pursuant to a mortgage loan (the “SST IV CMBS Loan”). This fixed rate loan encumbers seven properties owned by us (Jensen Beach, Texas City, Riverside, Las Vegas IV, Puyallup, Las Vegas V, and Plant City). The separate assets of these encumbered properties are not available to pay our other debt. The loan has a maturity date of February 1, 2030. Monthly payments due under the loan agreement (the “SST IV CMBS Loan Agreement”) are interest only, with the full principal amount becoming due and payable on the maturity date. (5) As of March 31, 2023, a Total Leverage Ratio Event (as defined below) had occurred, and the interest rate on such Note increased to 5.28% prospectively. For additional information regarding this loan, see 2032 Private Placement Notes below. (6) The amounts shown above are in USD based on the foreign exchange rate in effect as of the date presented. (7) This loan incurs interest at an all in rate of CORRA (as defined further below under the section entitled “2027 NBC Loan”), plus a CORRA adjustment effective interest rate on this loan is 6.42% when factoring the effects of a CORRA Swap which we entered into with the National Bank of Canada for the initial term of the loan. The Dufferin, Oakville II, Burlington II, Iroquois Shore Rd, and Stoney Creek I properties are encumbered by this loan. See Note 7 – Derivative Instruments for additional information. (8) On November 16, 2023, we, through eight of our wholly-owned Canadian subsidiaries entered into a term loan (the “2028 Canadian Term Loan”) with affiliates of QuadReal Finance LP, receiving net proceeds of $110.0 million CAD on such date. The 2028 Canadian Term Loan is secured by eight Canadian properties, has a maturity date of December 1, 2028, and carries a fixed interest rate for the term of the loan of 6.41%. The first two years of the Canadian Term Loan are interest only, after which it requires monthly amortizing payments based on a 25-year amortization schedule. The weighted average interest rate on our consolidated debt, excluding the impact of our interest rate hedging activities, as of September 30, 2024 was approximately 6.1%. We are subject to certain restrictive covenants, as amended, relating to the outstanding debt, and as of September 30, 2024, we were in compliance with all such covenants. KeyBank Bridge Loan On July 31, 2024, we entered into a bridge loan with KeyBank for up to $45.0 million (the “KeyBank Bridge Loan”) which matures on July 31, 2025. The KeyBank Bridge Loan was able to be funded in up to two draws, neither of which could occur after 90 days from closing. No amounts borrowed and repaid under such loan were available to be redrawn. At closing, we drew $20.0 million. There were no subsequent draws within 90 days after initial closing, and we no longer have the ability to draw additional funds pursuant to this loan. The KeyBank Bridge Loan was completed in connection with SSGT III’s acquisition of two self storage facilities on July 31, 2024, whereby our Operating Partnership provided a similar bridge loan to an indirect wholly-owned subsidiary of SSGT III for $20.0 million (the “SSGT III Bridge Loan”) to facilitate SSGT III’s closing on such properties. An indirect wholly-owned subsidiary of SSGT III is sponsoring a private offering of beneficial interests in a Delaware statutory trust (“DST”) relating to the two properties. We, through a newly formed subsidiary of SmartStop REIT Advisors, LLC (“SRA”), will serve as property manager of both of these properties. The KeyBank Bridge Loan incurs interest based on adjusted daily simple SOFR plus 275 basis points. The SSGT III Bridge Loan incurs interest based on adjusted daily simple SOFR plus 300 basis points. The SSGT III Bridge Loan is secured by an indirect pledge of equity in the entity sponsoring the private DST offering relating to the two properties mentioned above, as well as a full guaranty by SSGT III OP. We have pledged the SSGT III Bridge Loan to KeyBank as the collateral for the KeyBank Bridge Loan, as well as provided a full guaranty from our Operating Partnership. As such sponsor entity sells such DST interests, it is required to utilize such net proceeds to pay down the SSGT III Bridge Loan and we are similarly required to use such net proceeds to pay down the KeyBank Bridge Loan. In any event, we will be required to pay down at least 15% of the balance within four months, 35% within six months, 55% within nine months, and 75% within twelve months from the final draw. Full repayment is subject to one six month extension option. Similar required paydowns are also required of SSGT III pursuant to the terms of the SSGT III Bridge Loan. 2024 Credit Facility On February 22, 2024, we through our Operating Partnership (the “Borrower”), entered into an amended and restated revolving credit facility with KeyBank, National Association, as administrative agent and collateral agent, certain others listed as joint book runners, joint lead arrangers, syndication agents and documentation agents, and certain other lenders party thereto, (the “2024 Credit Facility”). The 2024 Credit Facility replaced the Credit Facility (defined below) the Company entered into on March 17, 2021, and has a maturity date of February 22, 2027. The aggregate commitment of the 2024 Credit Facility is $650 million. The Borrower has the right to request to increase the commitment amount available under the 2024 Credit Facility by an additional $850 million, for a total potential maximum aggregate amount of $1.5 billion, subject to certain conditions. The 2024 Credit Facility also includes sublimits of (a) up to $25 million for letters of credit and (b) up to $25 million for swingline loans; each of these sublimits are part of, and not in addition to, the amounts available under the 2024 Credit Facility. Borrowings under the 2024 Credit Facility may be in either USD or CAD. Upon the closing of the 2024 Credit Facility, we immediately drew down an aggregate amount of $576 million, which was used primarily to pay off the amounts outstanding under the Credit Facility. The maturity date of the 2024 Credit Facility is February 22, 2027, subject to a one-year extension option, subject to the payment of an extension fee of 0.20% on the aggregate amount of the then-outstanding revolving commitments for such extension, and it may be prepaid or terminated at any time without penalty; provided, however, that the lenders shall be indemnified for certain breakage costs. Amounts borrowed under the 2024 Credit Facility bear interest based on the type of borrowing (either Base Rate Loans, Daily Simple SOFR Loans, Term SOFR Loans or CORRA Loans, each as defined in the 2024 Credit Facility). Base Rate Loans bear interest at the lesser of (x) the Base Rate (as defined in the 2024 Credit Facility) plus the applicable rate, or (y) the maximum rate. Daily Simple SOFR Loans bear interest at the lesser of (a) Adjusted Daily Simple SOFR (as defined in the 2024 Credit Facility) plus the applicable rate, or (b) the maximum rate. Term SOFR Loans bear interest at the lesser of (a) Term SOFR (as defined in the 2024 Credit Facility) for the interest period in effect plus the applicable rate, or (b) the maximum rate. CORRA Loans bear interest at the lesser of (a) Adjusted Daily Simple CORRA (as defined in the 2024 Credit Facility) plus the applicable rate, or (b) the maximum rate. The corresponding applicable rate varies between (i) prior to a Security Interest Termination Event (defined below), 165 basis points to 230 basis points for Daily Simple SOFR Loans, Term SOFR Loans and CORRA Loans and between 65 basis points and 130 basis points for Base Rate Loans, in each case of this clause (i), depending on the consolidated leverage ratio of the Company and (ii) following a Security Interest Termination Event, 140 basis points to 225 basis points for Daily Simple SOFR Loans, Term SOFR Loans and CORRA Loans and between 40 basis points and 125 basis points for Base Rate Loans, in each case of this clause (ii), depending on the consolidated capitalization rate leverage ratio of the Company. Initial advances under the 2024 Credit Facility are Daily Simple SOFR Loans that bear interest at 175 basis points over Adjusted Daily Simple SOFR. The 2024 Credit Facility is also subject to an annual unused fee based upon the average amount of the unused portion of the 2024 Credit Facility, which varies from 15 bps to 25 bps, depending on the size of the unused amount, as well as whether a Security Interest Termination Event has occurred. As of September 30, 2024, borrowings under the 2024 Credit Facility only bore interest based on Daily Simple SOFR. The rate spread above Daily Simple SOFR at which the 2024 Credit Facility incurs interest is subject to increase based on the consolidated leverage ratio. There are five leverage tiers under the 2024 Credit Facility, with the highest tier limited to a maximum leverage of 60% and a maximum spread of 230 basis points on the 2024 Credit Facility. During the three months ended September 30, 2024, our consolidated leverage ratio was within the second leverage tier, and this loan incurred interest at daily simple SOFR plus a spread of 1.85% and the SOFR Index Adjustment of 0.10%. The 2024 Credit Facility is fully recourse, jointly and severally, to us, the Borrower, and certain of our subsidiaries (the “Subsidiary Guarantors”). In connection with the 2024 Credit Facility, we, the Borrower and the Subsidiary Guarantors executed guarantees in favor of the lenders. It is an event of default under the 2024 Credit Facility if (a) there is a payment default by us, the Borrower or any Subsidiary Guarantor under any recourse debt for borrowed money, (b) there is a payment default by us or any of its subsidiaries under any non-recourse debt of at least $75 million or (c) prior to a Security Interest Termination Event, an event of default occurs under the 2032 Private Placement Notes. The 2024 Credit Facility is initially secured by a pledge of equity interests in the Subsidiary Guarantors. However, upon the achievement of certain security interest termination conditions, the pledges shall be released and the 2024 Credit Facility shall become unsecured (the “Security Interest Termination Event”). The Security Interest Termination Event occurs at the Borrower’s election, once the Borrower satisfies all of the following security interest termination conditions: (i) a fixed charge coverage ratio of no less than 1.50:1.00; (ii) an unsecured interest coverage ratio of not less than 2.00:1.00; (iii) a consolidated capitalization rate leverage ratio of not greater than 60%; and (iv) a secured debt ratio of no greater than 40%. Following the occurrence of the Security Interest Termination Event, certain terms and conditions of the 2024 Credit Facility are modified, including, but not limited to: (i) in certain circumstances, a reduction in the applicable rate under the 2024 Credit Facility, (ii) the modification or addition of certain financial covenants, (iii) the addition of a floor of at least $25 million for any cross-defaulted recourse debt of us, Borrower or any Subsidiary Guarantor, and (iv) in certain circumstances, a reduction in the annual unused fee for the 2024 Credit Facility. The outstanding 2032 Private Placement Notes previously issued by us remain pari passu with the 2024 Credit Facility. The 2024 Credit Facility contains certain customary representations and warranties, affirmative, negative and financial covenants, borrowing conditions, and events of default. In particular, the financial covenants imposed on us include: a maximum leverage ratio, a minimum fixed charge coverage ratio, a minimum tangible net worth, certain limits on both secured debt and secured recourse debt, certain payout ratios of dividends paid to adjusted funds from operations, limits on unhedged variable rate debt, and minimum liquidity. If an event of default occurs and continues, the Borrower is subject to certain actions by the administrative agent, including, without limitation, the acceleration of repayment of all amounts outstanding under the 2024 Credit Facility. Subsequent to the initial draw on the 2024 Credit Facility, during the three months ended September 30, 2024, we borrowed an additional $67.5 million in order to fund our acquisitions of the Spartanburg and Miami Properties, to lend to the Managed REITs, and to fund other general corporate activities. Subsequent to the initial draw on the 2024 Credit Facility, during the nine months ended September 30, 2024, we borrowed an additional $83.0 million in order to fund our acquisitions of the Colorado Springs II, Spartanburg and Miami Properties, to lend to the Managed REITs, and to fund other general corporate activities. During the nine months ended September 30, 2024, the Colorado Springs II Property was added to the borrowing base of the 2024 Credit Facility. As of September 30, 2024, 90 of our wholly-owned properties were encumbered by the 2024 Credit Facility, and we had borrowed approximately $604 million of the $650 million maximum potential current commitment of the 2024 Credit Facility. The availability of the Credit Facility is subject to certain calculations, including a debt service coverage ratio (“DSCR”) calculation which utilizes prevailing treasury rates within the calculation. As of September 30, 2024, based on the aforementioned and other borrowing base calculations, we had the ability to draw up to an additional approximately $46.1 million on the current capacity of the revolver. 2027 NBC Loan On March 7, 2024, we, through five of our wholly-owned Canadian subsidiaries (the “2027 NBC Loan Borrowers”), entered into a loan with National Bank of Canada (“NBC”) as administrative agent, National Bank Financial as lead arranger and sole bookrunner, and certain other lenders party thereto (the “2027 NBC Loan”). On such date, we drew the maximum aggregate borrowing of $75 million CAD pursuant to the 2027 NBC Loan. This loan is secured by the five properties owned by the 2027 NBC Loan Borrowers (the “Secured NBC Properties”). Previously, four of the Secured NBC Properties were included in the borrowing base of the 2024 Credit Facility, and the other property was unencumbered. The net proceeds from the 2027 NBC Loan were used to pay down the 2024 Credit Facility by approximately $55.1 million USD, and accordingly, the respective four properties were released as collateral from the 2024 Credit Facility. The 2027 NBC Loan has a maturity date of March 7, 2027, which may be extended for additional one-year periods in the discretion of the lenders. The 2027 NBC Loan carries a variable interest rate based on either the Canadian Overnight Repo Rate Average (“CORRA”) or the Canadian Prime Rate. As of September 30, 2024, borrowings under the 2027 NBC Loan were subject to interest at the CORRA rate, plus a CORRA adjustment of approximately 0.30%, plus a spread of 2.20%. On March 12, 2024, we entered into an interest rate swap agreement based on CORRA with NBC whereby, inclusive of the swap we fixed the interest rate on the NBC loan at 6.42% for the initial three year term of the loan. The 2027 NBC Loan requires monthly amortizing principal and interest payments, which are based on a 25-year amortization schedule. The 2027 NBC Loan may be prepaid, in whole or in part, at any time upon prior written notice to the lenders, subject to interest rate swap breakage costs. SmartStop and the 2027 NBC Loan Borrowers provided an ordinary course environmental indemnity in favor of NBC and the lenders. SmartStop serves as a non-recourse guarantor, and each borrower provided a limited recourse guaranty up to the amount of the collateral pledged by it, under the 2027 NBC Loan. 2032 Private Placement Notes On April 19, 2022, we as guarantor, and our Operating Partnership as issuer, entered into a note purchase agreement (the “Note Purchase Agreement”) which provides for the private placement of $150 million of 4.53% Senior Notes due April 19, 2032 (the “2032 Private Placement Notes”). The sale and purchase of the 2032 Private Placement Notes occurred in two closings, with the first of such closings having occurred on April 19, 2022 with $75 million aggregate principal amount of the 2032 Private Placement Notes having been issued on such date (the “First Closing”) and the second of such closings having occurred on May 25, 2022 with $75 million aggregate principal amount of the 2032 Private Placement Notes having been issued on such date (the “Second Closing”). Interest on each series of the 2032 Private Placement Notes is payable semiannually on the nineteenth day of April and October in each year. Interest payable on the Notes was originally subject to a prospective 75 basis points increase, if, as of March 31, 2023, the ratio of total indebtedness to EBITDA (the “Total Leverage Ratio”) of the Company and its subsidiaries, on a consolidated basis, was greater than 7.00 to 1.00 (a “Total Leverage Ratio Event”). As of March 31, 2023, such Total Leverage Ratio Event occurred, and our 2032 Private Placement Notes began accruing interest at a rate of 5.28%. The interest accruing on the 2032 Private Placement Notes will continue to accrue at 5.28% until such time as the Total Leverage Ratio is less than or equal to 7.00 to 1.00 for two consecutive fiscal quarters, upon such achievement, the applicable fixed interest rate will revert to 4.53% and remain at that interest rate through maturity, regardless of our future Total Leverage Ratio. We are permitted to prepay at any time all, or from time to time, any part of the Notes in amounts not less than 5% of the 2032 Private Placement Notes then outstanding at (i) 100% of the principal amount so prepaid and (ii) the make-whole amount (as defined in the Note Purchase Agreement). The “Make-Whole Amount” is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the 2032 Private Placement Notes being prepaid over the amount of such 2032 Private Placement Notes. In addition, in connection with a change of control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the 2032 Private Placement Notes at 100% of the principal amount plus accrued and unpaid interest thereon, but without the Make Whole Amount or any other prepayment premium or penalty of any kind. The Company must also maintain a debt rating of the 2032 Private Placement Notes by a rating agency. The Note Purchase Agreement contains certain customary representations and warranties, affirmative, negative and financial covenants, and events of default that were substantially similar to the previously existing Credit Facility (defined below). The 2032 Private Placement Notes were issued on a pari passu basis with the previously existing Credit Facility, and are pari passu with the 2024 Credit Facility. As such, the Company and certain of its subsidiaries (the “Subsidiary Guarantors”) fully and unconditionally guarantee the Operating Partnership’s obligations under the 2032 Private Placement Notes. The 2032 Private Placement Notes were initially secured by a pledge of equity interests in the Subsidiary Guarantors on similar terms as the previously existing Credit Facility. On April 26, 2024, we amended the Note Purchase Agreement dated April 19, 2022 (the “NPA Amendment”). The primary purpose of the NPA Amendment was to make certain conforming changes between the Note Purchase Agreement and our recently amended and restated revolving credit facility, the 2024 Credit Facility. In particular, the NPA Amendment conformed certain of the definitions related to the financial tests that we are required to maintain, as well as certain of the property pool covenants we are required to satisfy, in the Note Purchase Agreement during the term thereof to those in the 2024 Credit Facility. Credit Facility On March 17, 2021, we, through our Operating Partnership (the “Borrower”), entered into a credit facility with KeyBank, National Association, as administrative agent, KeyBanc Capital Markets, Inc., Wells Fargo Securities, Citibank, N.A., and BMO Capital Markets, Corp., as joint book runners and joint lead arrangers, and certain other lenders party thereto (the “Credit Facility”). The initial aggregate amount of the Credit Facility was $500 million, which consisted of a $250 million revolving credit facility (the “Credit Facility Revolver”) and a $250 million term loan (the “Credit Facility Term Loan”). On October 7, 2021, the Borrower and lenders who were party to the Credit Facility amended the Credit Facility to increase the commitment on the Credit Facility by $200 million. In connection with the increased commitment, additional lenders were added to the Credit Facility. As a result of this amendment, the aggregate commitment on the Credit Facility was $700 million. The Credit Facility was repaid in full on February 22, 2024 in connection with the establishment of the 2024 Credit Facility. The following table presents the future principal payments required on outstanding debt as of September 30, 2024 (in thousands): 2024 $ 915 2025 8,948 2026 94,333 2027 706,122 2028 78,431 2029 and thereafter 294,500 Total payments 1,183,249 Debt issuance costs, net (3,345 ) Total $ 1,179,904	Note 5.

The separate assets of these encumbered properties are not available to pay our other debts. (2) This fixed rate loan encumbers five properties (Pompano Beach, Lake Worth, Jupiter, Royal Palm Beach, and Delray) with monthly interest only payments until June 2022, at which time both interest and principal payments became due monthly. The separate assets of these encumbered properties are not available to pay our other debts. (3) This fixed rate, interest only loan encumbers 10 properties (Myrtle Beach I, Myrtle Beach II, Port St. Lucie, Plantation, Sonoma, Las Vegas I, Las Vegas II, Las Vegas III, Ft Pierce, and Nantucket Island). The separate assets of these encumbered properties are not available to pay our other debts. (4) On March 17, 2021, in connection with the SST IV Merger, we assumed a $40.5 million fixed rate CMBS financing with KeyBank as the initial lender pursuant to a mortgage loan (the “SST IV CMBS Loan”). This fixed rate loan encumbers seven properties owned by us (Jensen Beach, Texas City, Riverside, Las Vegas IV, Puyallup, Las Vegas V, and Plant City). The separate assets of these encumbered properties are not available to pay our other debt. The loan has a maturity date of February 1, 2030. Monthly payments due under the loan agreement (the “SST IV CMBS Loan Agreement”) are interest only, with the full principal amount becoming due and payable on the maturity date. (5) As of March 31, 2023, a Total Leverage Ratio Event (as defined below) had occurred, and the interest rate on such Note increased to 5.28% prospectively. For additional information regarding this loan, see below. (6) On April 15, 2021, we purchased the Oakville III Property. We partially financed the Oakville III Property acquisition with a loan from Bank of Montreal (the “Oakville III BMO Loan”), which was secured by a first lien on the Oakville III Property. The loan is denominated in Canadian dollars (7) The amounts shown above are in USD based on the foreign exchange rate in effect as of the date presented. The weighted average interest rate on our consolidated debt, excluding the impact of our interest rate hedging activities, as of December 31, 2023 was approximately 6.1%. We are subject to certain restrictive covenants relating to the outstanding debt, and as of December 31, 2023, we were in compliance with all such covenants. 2028 Canadian Term Loan On November 16, 2023, we, through eight of our wholly-owned Canadian subsidiaries (the “Canadian Term Loan Borrowers”), entered into a term loan (the “2028 Canadian Term Loan”) with affiliates of QuadReal Finance LP (“QuadReal”). The 2028 Canadian Term Loan has an aggregate borrowing capacity of $110 million CAD and is secured by the eight properties owned by the Canadian Term Loan Borrowers (the “Canadian Term Loan Secured Properties”). Previously, the Canadian Term Loan Secured Properties were included in the borrowing base of the Credit Facility (defined below). The net proceeds of approximately $110 million CAD from the 2028 Canadian Term Loan were used to pay down the revolving portion of the Credit Facility, and accordingly, the eight Canadian Term Loan Secured Properties were released from the borrowing base of the Credit Facility. The 2028 Canadian Term Loan has a maturity date of December 1, 2028, and carries a fixed interest rate for the term of the loan of 6.41%. The first two years of the Canadian Term Loan are interest only, after which it requires monthly amortizing payments based on a 25-year amortization schedule. If the Canadian Term Loan is prepaid prior to the third anniversary, the Company must make a yield maintenance payment. After the third anniversary, any prepayment of the loan are subject to an exit fee, which is equal to a percentage of the then outstanding principal amount, as follows: (i) 100 bps if the prepayment occurs between the third and fourth anniversaries; and (ii) 75 bps if the prepayment occurs after the fourth anniversary . We provided an indemnity in favor of QuadReal for certain environmental matters and pursuant to which we also provided a non-recourse carveout guaranty. 2032 Private Placement Notes On April 19, 2022, we as guarantor, and our Operating Partnership as issuer, entered into a note purchase agreement (“The Note Purchase Agreement”) which provides for the private placement of $150 million of 4.53% Senior Notes due April 19, 2032 (the “2032 Private Placement Notes”). The sale and purchase of the 2032 Private Placement Notes occurred in two closings, with the first of such closings having occurred on April 19, 2022 with $75 million aggregate principal amount of the 2032 Private Placement Notes having been issued on such date (the “First Closing”) and the second of such closings having occurred on May 25, 2022 with $75 million aggregate principal amount of the 2032 Private Placement Notes having been issued on such date (the “Second Closing”). Interest on each series of the 2032 Private Placement Notes will be payable semiannually on the nineteenth day of April and October in each year. Interest payable on the Notes was originally subject to a prospective 75 basis points increase, if, as of March 31, 2023, the ratio of total indebtedness to EBITDA (the “Total Leverage Ratio”) of the Company and its subsidiaries, on a consolidated basis, was greater than 7.00 to 1.00 (a “Total Leverage Ratio Event”). As of March 31, 2023, such Total Leverage Ratio Event occurred, and our 2032 Private Placement Notes began accruing interest at a rate of 5.28%. The interest accruing on the 2032 Private Placement Notes will continue We are permitted to prepay at any time all, or from time to time any part of the Notes in amounts not less than 5% of the 2032 Private Placement Notes then outstanding at (i) 100% of the principal amount so prepaid and (ii) the make-whole amount (as defined in the Note Purchase Agreement). The “Make-Whole Amount” is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the 2032 Private Placement Notes being prepaid over the amount of such 2032 Private Placement Notes. In addition, in connection with a change of control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the 2032 Private Placement Notes at 100% of the principal amount plus accrued and unpaid interest thereon, but without the Make Whole Amount or any other prepayment premium or penalty of any kind. The Company must also maintain a debt rating of the 2032 Private Placement Notes by a rating agency. The Note Purchase Agreement contains certain customary representations and warranties, affirmative, negative and financial covenants, and events of default that are substantially similar to our existing Credit Facility (defined below). The 2032 Private Placement Notes have been issued on a pari passu basis with the Credit Facility, and as such, the Company and certain of its subsidiaries (the “Subsidiary Guarantors”) fully and unconditionally guarantee the Operating Partnership’s obligations under the 2032 Private Placement Notes. The 2032 Private Placement Notes are initially secured by a pledge of equity interests in the Subsidiary Guarantors on similar terms as the Credit Facility. The proceeds from the 2032 Private Placement Notes were used primarily to pay off existing debt and to pay off certain existing indebtedness of SSGT II in connection with the SSGT II Merger. Credit Facility On March 17, 2021, we, through our Operating Partnership (the “Borrower”), entered into a credit facility with KeyBank, National Association, as administrative agent, KeyBanc Capital Markets, Inc., Wells Fargo Securities, Citibank, N.A., and BMO Capital Markets Corp., as joint book runners and joint lead arrangers, and certain other lenders party thereto (the “Credit Facility”). The initial aggregate amount of the Credit Facility was $500 million, which consisted of a $250 million revolving credit facility (the “Credit Facility Revolver”) and a $250 million term loan (the “Credit Facility Term Loan”). The Borrower had the right to increase the amount available under the Credit Facility by an additional $350 million (the “Accordion Feature”), for an aggregate amount of $850 million, subject to certain conditions. The Credit Facility also includes sublimits of (a) up to $25 million for letters of credit and (b) up to $25 million for swingline loans; each of these sublimits are part of, and not in addition to, the amounts available under the Credit Facility Revolver. Borrowings under the Credit Facility may be in either U.S. dollars or Canadian dollars. The maturity date of the Credit Facility Revolver is March 17, 2024, subject to a one-year no On October 7, 2021, the Borrower and lenders who were party to the Credit Facility amended the Credit Facility to increase the commitment on the Credit Facility Revolver by $200 million for a total commitment of $450 million. In connection with the increased commitments, additional lenders were added to the Credit Facility. The commitments on the Credit Facility Term Loan remain unchanged. As a result of this amendment, the aggregate commitment on the Credit Facility is now $700 million. In addition, the Accordion Feature was also amended such that Borrower has the right to increase the aggregate amount of the Credit Facility by an additional $350 million, for an aggregate amount of up to $1.05 billion, subject to certain conditions. On April 19, 2022, we amended the Credit Facility (the “Credit Facility Amendment”). The primary purpose of the Credit Facility Amendment was to: (i) facilitate the issuance of the 2032 Private Placement Notes, (ii) make conforming changes between the Note Purchase Agreement and the Credit Facility, and (iii) modify the Credit Facility to reflect a transition from London Interbank Offer Rate (“LIBOR”) to secured overnight financing rate (“SOFR”) for floating rate borrowings. As of December 31, 2023, advances under the Credit Facility Term Loan incurred interest at a 160 basis points spread over daily simple SOFR plus an additional 10 basis points (the “SOFR Index Adjustment”) or 30-day 30-day The rate spreads above daily simple SOFR plus the SOFR Index Adjustment or CDOR at which the Credit Facility incurs interest are subject to increase based on the consolidated leverage ratio. There are five leverage tiers under the Credit Facility, with the highest tier limited to a maximum leverage of 60% and maximum spreads of 225 basis points and 230 basis points on the Term Loan and the Credit Facility Revolver, respectively. As of December 31, 2023, the consolidated leverage ratio was within the first (i.e. the lowest) leverage tier. The Credit Facility is fully recourse, jointly and severally, to us, our Operating Partnership, and certain of our subsidiaries (the “Subsidiary Guarantors”). In connection with this, we, our Operating Partnership, and our Subsidiary Guarantors executed guarantees in favor of the lenders. The Credit Facility is also cross-defaulted to (i) any recourse debt of ours, our Operating Partnership, or the Subsidiary Guarantors and (ii) any non-recourse The Credit Facility is initially secured by a pledge of equity interests in the Subsidiary Guarantors. However, upon the achievement of certain security interest termination conditions, the pledges shall be released and the Credit Facility shall become unsecured. The Credit Facility contains certain customary representations and warranties, affirmative, negative and financial covenants, borrowing conditions, and events of default. In particular, the financial covenants imposed include: a maximum leverage ratio, a minimum fixed charge coverage ratio, a minimum tangible net worth, certain limits on both secured debt and secured recourse debt, certain payout ratios of dividends paid to core funds from operations, limits on unhedged variable rate debt, and minimum liquidity. If an event of default occurs and continues, the Borrower is subject to certain actions by the administrative agent, including, without limitation, the acceleration of repayment of all amounts outstanding under the Credit Facility. In connection with the 2028 Canadian Term Loan, on November 16, 2023, eight properties were released from the borrowing base of the Credit Facility, and two properties were added to the borrowing base of the Credit Facility. As of December 31, 2023, 93 of our wholly-owned properties were encumbered by the Credit Facility. As of December 31, 2023, we had borrowed approximately $318.7 million of the $450 million maximum potential current capacity of the Credit Facility Revolver and all $250 million of the $250 million capacity on the Credit Facility Term Loan. The availability of the Credit Facility is subject to certain calculations, including a debt service coverage ratio (“DSCR”) calculation which utilizes prevailing treasury rates within the calculation. As of December 31, 2023, based on the aforementioned and other borrowing base calculations, we had the ability to draw up to an additional approximately $87.2 million on the Credit Facility Revolver. The following table presents the future principal payments required on outstanding debt as of December 31, 2023: 2024 $ 321,423,329 2025 2,987,627 2026 343,312,927 2027 49,594,599 2028 79,968,686 2029 and thereafter 294,500,000 Total payments 1,091,787,168 Discount on secured debt (80,227 ) Debt issuance costs, net (4,305,607 ) Total $ 1,087,401,334 On February 22, 2024, we entered into an amended and restated revolving credit facility with KeyBank (the “2024 Credit Facility”). The 2024 Credit Facility replaces the Credit Facility we entered into on March 17, 2021, and has a maturity date of February 22, 2027. Additionally, on March 7, 2024, we entered into a $75 million CAD term loan with National Bank of Canada (the “2027 NBC Loan”), which has a maturity date of March 7, 2027.

Equity [Abstract]
Preferred Equity	Note 6. Preferred Equity Series A Convertible Preferred Stock On October 29, 2019 (the “Commitment Date”), we entered into a preferred stock purchase agreement (the “Purchase Agreement”) with Extra Space Storage LP (the “Investor”), a subsidiary of Extra Space Storage Inc. (NYSE: EXR), pursuant to which the Investor committed to purchase up to $200 million in preferred shares (the aggregate shares to be purchased, the “Preferred Shares”) of our new Series A Convertible Preferred Stock (the “Series A Convertible Preferred Stock”), in one or more closings (each, a “Closing,” and collectively, the “Closings”). The initial closing (the “Initial Closing”) in the amount of $150 million occurred on the Commitment Date, and the second and final closing in the amount of $50 million occurred on October 26, 2020. We incurred approximately $3.6 million in issuance costs related to the Series A Convertible Preferred Stock, which were recorded as a reduction to Series A Convertible Preferred stock on our consolidated balance sheets. The shares of Series A Convertible Preferred Stock rank senior to all other shares of our capital stock, including our common stock, with respect to rights to receive dividends and to participate in distributions or payments upon any voluntary or involuntary liquidation, dissolution or winding up of the Company. Dividends payable on each share of Series A Convertible Preferred Stock were initially equal to a rate of 6.25% per annum. The dividend rate increased by an additional 0.75% per annum to an aggregate of 7.0% per annum on October 29, 2024. The dividend rate will increase an additional 0.75% per annum each year thereafter to a maximum of 9.0% per annum until the tenth anniversary of the Initial Closing, unless the Series A Convertible Preferred Stock is redeemed or repurchased in full. The dividends are payable in arrears for the prior calendar quarter on or before the 15 th Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of Series A Convertible Preferred Stock will be entitled to receive a payment equal to the greater of (i) aggregate purchase price of all outstanding Preferred Shares, plus any accrued and unpaid dividends (the “Liquidation Amount”) and (ii) the amount that would have been payable had the Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to such liquidation. Subject to certain additional redemption rights, as described herein, we have the right to redeem the Series A Convertible Preferred Stock for cash. The amount of such redemption will be equal to the Liquidation Amount. Upon the listing of our common stock on a national securities exchange (the “Listing”), we have the right to redeem any or all outstanding Series A Convertible Preferred Stock at an amount equal to the greater of (i) the amount that would have been payable had such Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to the Listing, and then all of such Preferred Shares were sold in the Listing, or (ii) the Liquidation Amount. Upon a change of control event, we have the right to redeem any or all outstanding Series A Convertible Preferred Stock at an amount equal to the greater of (i) the amount that would have been payable had the Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to such change of control or (ii) the Liquidation Amount. In addition, subject to certain cure provisions, if we fail to maintain our status as a real estate investment trust, the holders of Series A Convertible Preferred Stock have the right to require us to repurchase the Series A Convertible Preferred Stock at an amount equal to the Liquidation Amount with no Premium Amount. Subject to our redemption rights in the event of a listing or change of control described above, the holders of Series A Convertible Preferred Stock have the right to convert any or all of the Series A Convertible Preferred Stock held by such holders into common stock at a rate per share equal to the quotient obtained by dividing the Liquidation Amount by the conversion price. The conversion price is $10.66, as may be adjusted in connection with stock splits, stock dividends and other similar transactions. The holders of Series A Convertible Preferred Stock are not entitled to vote on any matter submitted to a vote of our stockholders, except that in the event that the dividend for the Series A Convertible Preferred Stock has not been paid for at least four quarters (whether or not consecutive), the holders of Series A Convertible Preferred Stock have the right to vote together with our stockholders on any matter submitted to a vote of our stockholders, upon which the holders of the Series A Convertible Preferred Stock and holders of common stock shall vote together as a single class. The number of votes applicable to a share of Series A Convertible Preferred Stock will be equal to the number of shares of common stock a share of Series A Convertible Preferred Stock could have been converted into as of the record date set for purposes of such stockholder vote. loan-to-value, In connection with the issuance of the Series A Convertible Preferred Stock, we and the Investor also entered into an investors’ rights agreement (the “Investors’ Rights Agreement”) which provides the Investor with certain customary protections, including demand registration rights and “piggyback” registration rights with respect to our common stock issued to the Investor upon conversion of the Preferred Shares. As of September 30, 2024, there were 200,000 Preferred Shares outstanding with an aggregate liquidation preference of approximately $203.1 million, which consists of $150 million from the Initial Closing, $50 million from a closing on October 26, 2020 and approximately $3.1 million of accumulated and unpaid distributions. As of December 31, 2023, there were 200,000 Preferred Shares outstanding with an aggregate liquidation preference of approximately $203.2 million, which consists of $150 million from the Initial Closing, $50 million from a closing on October 26, 2020 and approximately $3.2 million of accumulated and unpaid distributions.	Note 6. Preferred Equity Series A Convertible Preferred Stock On October 29, 2019 (the “Commitment Date”), we entered into a preferred stock purchase agreement (the “Purchase Agreement”) with Extra Space Storage LP (the “Investor”), a subsidiary of Extra Space Storage Inc.

The initial closing (the “Initial Closing”) in the amount of $150 million occurred on the Commitment Date, and the second and final closing in the amount of $50 million occurred on October 26, 2020. We incurred approximately $3.6 million in issuance costs related to the Series A Convertible Preferred Stock, which were recorded as a reduction to Series A Convertible Preferred stock on our consolidated balance sheets. The shares of Series A Convertible Preferred Stock rank senior to all other shares of our capital stock, including our common stock, with respect to rights to receive dividends and to participate in distributions or payments upon any voluntary or involuntary liquidation, dissolution or winding up of the Company. Dividends payable on each share of Series A Convertible Preferred Stock will initially be equal to a rate of 6.25% per annum. If the Series A Convertible Preferred Stock has not been redeemed on or prior to the fifth anniversary date of the Initial Closing (October 29, 2024), the dividend rate will increase an additional 0.75% per annum each year thereafter to a maximum of 9.0% per annum until the tenth anniversary of the Initial Closing, at which time the dividend rate shall increase 0.75% per annum each year thereafter until the Series A Convertible Preferred Stock is redeemed or repurchased in full. The dividends are payable in arrears for the prior calendar quarter on or before the 15 th Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of Series A Convertible Preferred Stock will be entitled to receive a payment equal to the greater of (i) aggregate purchase price of all outstanding Preferred Shares, plus any accrued and unpaid dividends (the “Liquidation Amount”) and (ii) the amount that would have been payable had the Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to such liquidation. Subject to certain additional redemption rights, as described herein, we have the right to redeem the Series A Convertible Preferred Stock for cash at any time following the fifth anniversary of the Initial Closing. The amount of such redemption will be equal to the Liquidation Amount. Upon the listing of our common stock on a national securities exchange (the “Listing”), we have the right to redeem any or all outstanding Series A Convertible Preferred Stock at an amount equal to the greater of (i) the amount that would have been payable had such Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to the Listing, and then all of such Preferred Shares were sold in the Listing, or (ii) the Liquidation Amount, plus a premium amount (the “Premium Amount”) of 10%, 8%, 6%, 4%, or 2% if redeemed prior to the first, second, third, fourth, or fifth anniversary dates of issuance, respectively, or 0% if redeemed thereafter, as set forth in the Articles Supplementary. Upon a change of control event, we have the right to redeem any or all outstanding Series A Convertible Preferred Stock at an amount equal to the greater of (i) the amount that would have been payable had the Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to such change of control or (ii) the Liquidation Amount, plus the Premium Amount, as set forth in the Articles Supplementary. In addition, subject to certain cure provisions, if we fail to maintain our status as a real estate investment trust, the holders of Series A Convertible Preferred Stock have the right to require us to repurchase the Series A Convertible Preferred Stock at an amount equal to the Liquidation Amount with no Premium Amount. Subject to our redemption rights in the event of a listing or change of control described above, upon the earlier to occur of (i) the second anniversary of the Initial Closing or (ii) 180 days after a Listing, the holders of Series A Convertible Preferred Stock have the right to convert any or all of the Series A Convertible Preferred Stock held by such holders into common stock at a rate per share equal to the quotient obtained by dividing the Liquidation Amount by the conversion price. The conversion price is $10.66, as may be adjusted in connection with stock splits, stock dividends and other similar transactions. The holders of Series A Convertible Preferred Stock are not entitled to vote on any matter submitted to a vote of our stockholders, except that in the event that the dividend for the Series A Convertible Preferred Stock has not been paid for at least four quarters (whether or not consecutive), the holders of Series A Convertible Preferred Stock have the right to vote together with our stockholders on any matter submitted to a vote of our stockholders, upon which the holders of the Series A Convertible Preferred Stock and holders of common stock shall vote together as a single class. The number of votes applicable to a share of Series A Convertible Preferred Stock will be equal to the number of shares of common stock a share of Series A Convertible Preferred Stock could have been converted into as of the record date set for purposes of such stockholder vote. This foregoing limited voting right shall cease when all past dividend periods have been paid in full. In addition, the affirmative vote of the holders of a majority of the outstanding shares of Series A Convertible Preferred Stock is required in certain customary circumstances, as well as other circumstances, such as (i) our real estate portfolio exceeding a leverage ratio of 60% loan-to-value, In connection with the issuance of the Series A Convertible Preferred Stock, we and the Investor also entered into an investors’ rights agreement (the “Investors’ Rights Agreement”) which provides the Investor with certain customary protections, including demand registration rights and “piggyback” registration rights with respect to our common stock issued to the Investor upon conversion of the Preferred Shares. As of December 31, 2023, there were 200,000 Preferred Shares outstanding with an aggregate liquidation preference of approximately $203.2 million, which consists of $150 million from the Initial Closing, $50 million from a closing on October 26, 2020 and approximately $3.2 million of accumulated and unpaid distributions. As of December 31, 2022, there were 200,000 Preferred Shares outstanding with an aggregate liquidation preference of approximately $203.2 million, which consists of $150 million from the Initial Closing, $50 million from a closing on October 26, 2020 and approximately $3.2 million of accumulated and unpaid distributions.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 7. Derivative Instruments Interest Rate Derivatives Our objectives in using interest rate derivatives are to add stability to our earnings (losses) and to manage our exposure to interest rate movements. To accomplish this objective, we have used interest rate swaps and caps as part of our interest rate risk management strategy. For interest rate derivatives designated and qualified as a hedge for GAAP purposes, the change in the fair value of the effective portion of the derivative is recorded in accumulated other comprehensive income (loss) (“AOCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to such derivatives will be reclassified to interest expense as interest payments are made on our variable rate debt. In addition, we classify cash flows from qualifying cash flow hedging relationships in the same category as the cash flows from the hedged items in our consolidated statements of cash flows. We do not use interest rate derivatives for trading or speculative purposes. Interest rate derivatives not designated as hedges for GAAP are not speculative and are used to manage our exposure to interest rate movements and other identified risks but we have elected not to apply hedge accounting. Changes in the fair value of interest rate derivatives not designated in hedging relationships are recorded in other income (expense) within our consolidated statements of operations. Foreign Currency Hedges Our objectives in using foreign currency derivatives are to add stability to potential fluctuations in exchange rates between foreign currencies and the U.S. dollar and to manage our exposure to exchange rate movements. To accomplish this objective, we have used foreign currency forwards and foreign currency options as part of our exchange rate risk management strategy. A foreign currency forward contract is a commitment to deliver a certain amount of currency at a certain price on a specific date in the future. By entering into the forward contract and holding it to maturity, we are locked into a future currency exchange rate in an amount equal to and for the term of the forward contract. A foreign currency option contract is a commitment by the seller of the option to deliver, solely at the option of the buyer, a certain amount of currency at a certain price on a specific date. For derivatives designated as net investment hedges for GAAP purposes, the changes in the fair value of the derivatives are reported in accumulated other comprehensive income. Amounts are reclassified out of accumulated other comprehensive income (loss) into earnings when the hedged net investment is either sold or substantially liquidated. The change in the value of the designated portion of our settled and unsettled foreign currency hedges is recorded net in foreign currency hedge contract gain (loss) in our consolidated statements of comprehensive income (loss) in the related period. The change in the value of the portion of our settled and unsettled foreign currency hedges that are not designated for hedge accounting for GAAP is recorded in other income (expense) within our consolidated statements of operations and represented a loss of approximately $0.4 million and a gain of approximately $3.8 million for the three months ended September 30, 2024 and 2023, respectively, and a gain of approximately $1.3 million and $0.6 million for the nine months ended September 30, 2024 and 2023, respectively. On April 12, 2021, we entered into an approximately $125.9 million CAD currency forward with a settlement date of April 12, 2023. On April 12, 2023, we settled this foreign currency forward and received approximately USD $6.4 million, and simultaneously entered into a new approximately $134.4 million CAD currency forward with a maturity date of July 6, 2023. On July 5, 2023, we settled this foreign currency forward and paid approximately USD $1.2 million, and simultaneously entered into a new approximately $132.4 million CAD currency forward with a settlement date of April 12, 2024. On April 12, 2024, we settled this hedge and we received approximately USD $3.5 million. We simultaneously entered into a new foreign currency hedge with a notional amount of $136,476,000 CAD at a strike rate of 1.3648 which matures on April 11, 2025. On October 12, 2022, we entered into a new $137.7 million CAD currency forward with a settlement date of October 12, 2023. On October 11, 2023, we rolled this hedge without any cash settlement, extending the maturity date to November 9, 2023 at a strike rate of 1.3766, and notional of $137,664,000 CAD. On November 9, 2023, we rolled this hedge without any cash settlement, extending the maturity date to November 16, 2023 at a strike rate of 1.3767, and notional of $137,669,000 CAD. On November 16, 2023, this hedge matured, and without any cash settlement, we simultaneously entered into a new $30.0 million CAD currency forward with a maturity date of January 16, 2024, and a strike rate of 1.3782. On January 16, 2024 we rolled this hedge without any cash settlement, effectively extending the maturity date to February 15, 2024 at a strike rate of 1.3781. Additionally, on February 16, 2024 we further rolled this hedge without any cash settlement at a strike rate of 1.3781. This hedge ultimately matured on March 7, 2024 whereby we owed and paid approximately $0.5 million at settlement. In connection with the 2027 NBC Loan borrowing, on March 12, 2024, we entered into a CORRA Swap with NBC with an initial notional amount of CAD $75,000,000 at a rate of 3.926% for the initial duration of the 2027 NBC Loan, maturing on March 7, 2027. The amortization of this swap corresponds with the amortizing principal payments on the related loan. On May 1, 2024, to hedge our exposure to potentially rising interest rates, we entered into three SOFR interest rate caps for a total of approximately $8.2 million. We deferred payment for these SOFR interest rate caps, and are recording these interest rate caps net of such deferred payment liability on our balance sheet.

Related Party Transactions	Note 10. Related Party Transactions Self Administration Transaction On June 28, 2019, we, our Operating Partnership and our TRS entered into a series of transactions, agreements, and amendments to our existing agreements and arrangements with our then-sponsor, SAM, and SmartStop OP Holdings, LLC (“SS OP Holdings”), a subsidiary of SAM, pursuant to which, effective June 28, 2019, we acquired the self storage advisory, asset management and property management businesses and certain joint venture interests of SAM, along with certain other assets of SAM (collectively, the “Self Administration Transaction”). As a result of the Self Administration Transaction, we became self-managed and succeeded to the advisory, asset management and property management businesses and certain joint ventures previously in place for us, SST IV (until the SST IV Merger Date), and SSGT II (until the SSGT II Merger Date), and we acquired the internal capability to originate, structure and manage additional future self storage investment products which would be sponsored by SmartStop REIT Advisors, LLC (“SRA”), our indirect subsidiary. The transfer agent agreement described below was not impacted by the Self Administration Transaction. Our Chief Executive Officer, who is also the Chairman of our board of directors, holds ownership interests in and is an officer of SAM, and other affiliated entities. Our Chief Executive Officer also previously indirectly held an ownership interest in our former dealer manager. Previously, certain of our executive officers and another member of our board of directors held ownership interests in and/or were officers of SAM, and other affiliated entities. Accordingly, any agreements or transactions we have entered into with such entities may present a conflict of interest. None of SAM and its affiliates or our directors or executive officers receive any compensation, fees or reimbursements from our Managed REITs, other than with respect to fees and reimbursements in accordance with the Administrative Services Agreement and the transfer agent agreement, or as otherwise described in this section. Former Transfer Agent Agreement SAM owns 100% of the membership interests of Strategic Transfer Agent Services, LLC, our former transfer agent (“Transfer Agent”), which is a registered transfer agent with the SEC. Pursuant to our transfer agent agreement, our Transfer Agent provided transfer agent and registrar services to us. These services were substantially similar to what a third party transfer agent would provide in the ordinary course of performing its functions as a transfer agent, including, but not limited to: providing customer service to our stockholders, processing the distributions and any servicing fees with respect to our shares and issuing regular reports to our stockholder. We believe that our Transfer Agent, through its knowledge and understanding of the direct participation program industry which includes non-traded Fees paid to our Transfer Agent included a fixed quarterly fee, one-time Effective as of April 29, 2024, we transitioned to a new transfer agent, SS&C GIDS, Inc. In connection with such transfer, we simultaneously terminated the transfer agent agreement with Strategic Transfer Agent Services, LLC. In lieu of a termination fee and in recognition of the additional cost and expenses incurred by our former transfer agent in connection with the transition, we paid a transition fee of $150,000 to Strategic Transfer Agent Services, LLC in May 2024. Pursuant to the terms of the agreements described above, the following table summarizes related party costs incurred and paid by us for the year ended December 31, 2023 and the nine months ended September 30, 2024, as well as any related amounts payable as of December 31, 2023 and September 30, 2024 (in thousands): Year Ended December 31, 2023 Nine Months Ended September 30, 2024 Incurred Paid Payable  Incurred   Paid   Payable  Expensed Transfer Agent fees $ 1,479 $ 1,473 $ 75 $ 648 $ 693 $ 30 Other Other —  —  341 —  —  341 Total $ 1,479 $ 1,473 $ 416 $ 648 $ 693 $ 371 Acquisition of Self Storage Platform from SAM and Other Transactions As a result of the Self Administration Transaction, we acquired the self storage sponsorship platform of SAM. Accordingly, the advisor and property manager entities of SST IV and SSGT II became our indirect subsidiaries, and we became entitled to receive various fees and expense reimbursements under the terms of the SST IV and SSGT II advisory and property management agreements as described below. In addition, we now also own the advisor and property manager entities of SST VI and SSGT III and are entitled to receive various fees and expense reimbursements under the terms of the SST VI and SSGT III advisory and property management agreements as described below. Advisory Agreement Fees Our indirect subsidiaries, the SST VI Advisor, and the SSGT III Advisor are or were entitled to receive various fees and expense reimbursements under the terms of the SST VI, and SSGT III advisory agreements. SST VI Advisory Agreement The SST VI Advisor provides acquisition and advisory services to SST VI pursuant to an advisory agreement (the “SST VI Advisory Agreement”). In connection with the SST VI private placement offering, SST VI was required to reimburse the SST VI Advisor for organization and offering costs from the SST VI private offering pursuant to the SST VI private offering advisory agreement. Pursuant to the SST VI Advisory Agreement, the SST VI Advisor receives acquisition fees equal to 1.00% of the contract purchase price of each property SST VI acquires plus reimbursement of any acquisition expenses that SST VI Advisor incurs. The SST VI Advisor also receives a monthly asset management fee equal to 0.0625%, which is one-twelfth A subsidiary of our Operating Partnership may also be potentially entitled to a subordinated distribution through its ownership of a special limited partnership in SST VI OP if SST VI (1) lists its shares of common stock on a national exchange, (2) terminates the SST VI Advisory Agreement, (3) liquidates its portfolio, or (4) merges with another entity or enters into an Extraordinary Transaction, as defined in SST VI OP’s limited partnership agreement. The SST VI Advisory Agreement provides for reimbursement of the SST VI Advisor’s direct and indirect costs of providing administrative and management services to SST VI. Beginning four fiscal quarters after commencement of SST VI’s public offering, which was declared effective March 17, 2022, the SST VI Advisor was required to pay or reimburse SST VI the amount by which SST VI’s aggregate annual operating expenses, as defined, exceed the greater of 2% of SST VI’s average invested assets or 25% of SST VI’s net income, as defined, unless a majority of SST VI’s independent directors determine that such excess expenses were justified based on unusual and non-recurring Pacific Oak Holding Group, LLC, is a 17.5% non-voting SSGT III Advisory Agreement The SSGT III Advisor provides acquisition and advisory services to SSGT III pursuant to an advisory agreement (the “SSGT III Advisory Agreement”). In connection with the SSGT III private placement offering, which became effective on May 18, 2022, SSGT III is required to reimburse the SSGT III Advisor for organization and offering costs from the SSGT III private offering pursuant to the SSGT III Advisory Agreement. Pursuant to the SSGT III Advisory Agreement, the SSGT III Advisor will receive acquisition fees equal to 1.00% of the contract purchase price of each property SSGT III acquires plus reimbursement of acquisition expenses that SSGT III Advisor incurs, provided, however, that no reimbursement shall be made for costs of personnel to the extent that such personnel perform services in transactions for which the Advisor receives the Acquisition Fee. The SSGT III Advisor also receives a monthly asset management fee equal to 0.0625%, which is one-twelfth of 0.75%, of SSGT III’s aggregate asset value, as defined. The SSGT III Advisor is also entitled to receive a disposition fee equal to 1.5% of the contract sale price for any properties sold inclusive of any real estate commissions paid to third party real estate brokers. Through a separate agreement, Pacific Oak Holding Group, LLC, the parent company of Pacific Oak Capital Markets, LLC, the dealer manager for the SSGT III private offering, is entitled to receive 17.5% of the acquisition fees, asset management fees and disposition fees SSGT III Advisor earns pursuant to the SSGT III Advisory Agreement. A subsidiary of our Operating Partnership may also be potentially entitled to various subordinated distributions through its ownership of a special limited partnership in SSGT III’s operating partnership agreement if SSGT III (1) lists its shares of common stock on a national exchange, (2) terminates the SSGT III Advisory Agreement, (3) liquidates its portfolio, or (4) merges with another entity or enters into an Extraordinary Transaction, as defined in the SSGT III operating partnership agreement. Managed REIT Property Management Agreements Our indirect subsidiaries, SS Growth Property Management II, LLC, Strategic Storage Property Management VI, LLC, and SS Growth Property Management III, LLC, (collectively the “Managed REITs Property Managers”), are or were entitled to receive fees for their services in managing the properties wholly or partially owned by the Managed REITs pursuant to property management agreements entered into between the owner of the property and the applicable Managed REIT’s Property Manager. The Managed REITs’ Property Managers will receive a property management fee equal to 6% of the gross revenues from the properties, generally subject to a monthly minimum of $3,000 per property, plus reimbursement of the costs of managing the properties, and a one-time on-site The SST VI and SSGT III property managers are or were entitled to a construction management fee equal to 5% of the cost of a related construction or capital improvement work project in excess of $10,000. Effective June 1, 2022, in connection with the SSGT II Merger, the SSGT II property management contracts were terminated. As a result of us acquiring SSGT II and terminating such contracts, we recorded a write-off In connection with the Self Administration Transaction, we previously recorded a deferred tax liability, which was the result of the difference between the GAAP carrying value of the SSGT II property management contract and the carrying value for tax purposes. As we reduced the GAAP carrying value of such intangible asset, we adjusted the value of our deferred tax liability on a pro-rata Summary of Fees and Revenue Related to the Managed REITs Pursuant to the terms of the various agreements described above for the Managed REITs, the following summarizes the related party fees for the three and nine months ended September 30, 2024 and 2023 (in thousands): Three Months Ended September 30, Nine Months Ended Managed REIT Platform Revenues   2024     2023     2024     2023   Asset Management Fees: SST VI $ 1,082 $ 1,062 $ 3,208 $ 2,378 SSGT III 367 296 1,039 690 1,449 1,358 4,247 3,068 Property Management Fees: SST VI 436 346 1,244 857 SSGT III 150 105 407 236 JV Properties 248 190 703 540 834 641 2,354 1,633 Tenant Protection Program Fees: SST VI 317 263 883 575 SSGT III 106 63 281 112 JV Properties 100 72 270 196 523 398 1,434 883 Acquisition Fees: SST VI —  —  34 2,465 SSGT III 103 —  162 642 103 —  196 3,107 Other Managed REIT Fees (1) 232 121 695 424 Managed REIT Platform Fees 3,141 2,518 8,926 9,115 Sponsor funding reduction (2) (218 ) —  (598 ) —  Total Managed REIT Platform Revenues $ 2,923 $ 2,518 $ 8,328 $ 9,115 (1) Such revenue primarily includes other property management related fees, construction management fees, development fees, and other miscellaneous revenues. (2) Pursuant to the Sponsor Funding Agreement, SmartStop funds certain costs of SST VI’s share sales, and in return receives Series C Units in SST VI’s OP. The excess of the funding over the value of the Series C Units received is accounted for as a reduction of Managed REIT Platform revenues from SST VI over the remaining estimated term of the management contracts with SST VI. We offer tenant insurance or tenant protection programs to customers at our Managed REITs’ properties pursuant to which we, as the property manager and majority owner of the Tenant Protection Program joint ventures, are entitled to substantially all of the net revenue attributable to the sale of such tenant programs. In order to protect our interest in receiving these revenues in light of the fact that the Managed REITs control the properties, we and the Managed REITs transferred our respective rights in such arrangements to a joint venture entity owned 99.9% by us through a TRS subsidiary and 0.1% by the Managed REIT. Under the terms of the operating agreements of the joint venture entities, we receive 99.9% of the net revenues generated from such Tenant Protection Programs and the Managed REIT receives the other 0.1% of such net revenues. Subsequent to the SSGT II Merger, the SSGT II Tenant Protection Programs joint ventures are wholly-owned by us and such revenue is generated at our now wholly-owned self storage properties and is recorded within ancillary operating revenue in our consolidated statements of operations. Reimbursable costs from Managed REITs includes reimbursement of SST IV (until the SST IV Merger Date), SSGT II (until the SSGT II Merger Date), SST VI and SSGT III’s Advisors’ certain direct and indirect costs of providing administrative and management services to the Managed REITs. Additionally, reimbursable costs includes reimbursement pursuant to the property management agreements for reimbursement of certain costs of managing the Managed REITs’ properties, including wages and salaries and other expenses of employees engaged in operating, managing and maintaining such properties. As of September 30, 2024 and December 31, 2023 we had receivables due from the Managed REITs totaling approximately $18.8 million and $6.5 million, respectively. Such amounts are included in investments in and advances to the Managed REITs line-item in our consolidated balance sheets. Such amounts included unpaid amounts relative to the above table, in addition to other direct reimbursable expenditures of the Managed REITs that we directly funded. Investments in and advances to SST VI OP Equity Investments On March 10, 2021, SmartStop OP made an investment of $5.0 million in SST VI OP, in exchange for common units of limited partnership interest in SST VI OP. Additionally, a subsidiary of SmartStop OP owns a special limited partnership interest (the “SST VI SLP”) in SST VI OP. For the three and nine months ended September 30, 2024 we recorded a loss related to our equity interest in SST VI OP of approximately $0.2 million, and $0.6 million, respectively, and received distributions in the amount of approximately $0.1 million, and $0.3 million, respectively. For the three and nine months ended September 30, 2023 we recorded a loss related to our equity interest, excluding our preferred investment discussed below, in SST VI OP of approximately $0.3 million, and $0.7 million, respectively, and received distributions in the amount of approximately $0.1 million, and $0.3 million, respectively. On January 30, 2023, a subsidiary of SmartStop made a preferred investment of 600,000 Series A Cumulative Redeemable Preferred units of limited partnership interest in SST VI OP for an aggregate of $15 million. Upon closing of the preferred investment, an investment fee equal to 1% of the investment amount was owed and paid by SST VI OP. SmartStop, through its subsidiary, received distributions, payable monthly in arrears, at a rate of 7.0% per annum from the date of issuance until the second anniversary of the date of issuance, 8.0% per annum commencing thereafter until the third anniversary of the date of issuance, 9.0% per annum commencing thereafter until the fourth anniversary of the date of issuance, and 10% per annum thereafter, payable monthly. On May 2, 2023, SST VI fully redeemed SmartStop’s preferred investment of 600,000 Series A Cumulative Redeemable Preferred units of limited partnership interest in SST VI OP, and repaid accrued distributions due as of the date of redemption for a total amount of approximately $15.1 million. Sponsor Funding Agreement On November 1, 2023, SRA, a subsidiary of our Operating Partnership, entered into a Sponsor Funding Agreement with SST VI and SST VI OP, in connection with certain changes to the public offering of SST VI. Pursuant to the Sponsor Funding Agreement, SRA, as sponsor of the SST VI offering, has agreed to fund the payment of (i) the upfront 3% sales commission for the sale of Class Y shares sold in the SST VI offering, (ii) the upfront 3% dealer manager fee for the Class Y shares sold in the SST VI offering, and (iii) the estimated 1% organization and offering expenses for the sale of Class Y shares and Class Z shares sold in the SST VI offering. SRA also agreed to reimburse SST VI in cash to cover the dilution from certain one-time stock dividends which were issued by SST VI to existing stockholders in connection with the sponsor funding changes to the SST VI offering. On December 15, 2023, we paid SST VI approximately $6.6 million for the reimbursement of the aforementioned stock dividend. In consideration for SRA providing the funding for the front-end sales load and the cash to cover the dilution from the stock dividends described above, SST VI OP will issue a number of Series C Units to SRA equal to the dollar amount of such funding divided by the then-current offering price for the Class Y shares and Class Z shares sold in the SST VI offering, which was initially $9.30 per share. Pursuant to the Sponsor Funding Agreement, SRA will reimburse SST VI monthly for the applicable front-end sales load it has agreed to fund, and SST VI OP will issue the Series C Units on a monthly basis upon such reimbursement. On August 7, 2024, SST VI declared an estimated net asset value per share of $10.00. Since the Series C Units that could be converted would result in the net asset value falling below $10.00 per share, none of the Series C Units we own were converted into class A units of SST VI OP, and our future purchases will be determined based on the current estimated net asset value at such time. Subsequent to SST VI declaring an estimated net asset value of $10.00 per share, the number of Series C Units SmartStop receives in exchange for funding the front-end sales load of the sale of SST VI’s class Y and class Z shares is calculated as the dollar amount of such sponsor funding divided by the current offering price of $10.00 per share for such class Y and Z shares. The Sponsor Funding Agreement will terminate immediately upon the date that SST VI ceases to offer the Class Y shares and Class Z shares in the SST VI offering. The SST VI offering was set to expire on March 17, 2024, and was extended to March 17, 2025 upon the approval of SST VI’s board of directors on February 1, 2024. Inclusive of all extension options available to SST VI, its current offering could not extend beyond September 12, 2025. On November 1, 2023, SRA entered into Amendment No. 3 to the Second Amended and Restated Limited Partnership Agreement of SST VI OP with SST VI and SST VI OP containing, among other things, the terms of the Series C Units. The Series C Units shall initially have no distribution, liquidation, voting, or other rights to participate in SST VI OP unless and until such Series C Units are converted into class A units of SST VI OP. The Series C Units shall automatically convert into class A units on a one-to-one basis upon SST VI’s disclosure of an estimated net asset value per share equal to at least $10.00 per share for each class of SST VI shares of common stock, including the Class Y shares and Class Z shares, calculated net of the Series C Units to be converted. Through September 30, 2024, we have incurred approximately $8.7 million in connection with the Sponsor Funding Agreement, representing approximately 928,000 subordinated units. During the three and nine months ended September 30, 2024 we incurred approximately $0.6 million and $1.8 million, respectively, of which approximately $0.2 million was accrued as a payable pursuant to the Sponsor Funding Agreement. As of September 30, 2024, the maximum remaining commitment of SRA pursuant to the Sponsor Funding Agreement is approximately $61.9 million if SST VI were to sell the maximum amount under its current offering of $1.0 billion. Debt Investments On December 30, 2021, in connection with SST VI’s acquisition of two self storage facilities, our Operating Partnership entered into a mezzanine loan agreement with a wholly-owned subsidiary of SST VI OP for up to $45 million (the “SST VI Mezzanine Loan”). The SST VI Mezzanine Loan required a commitment fee equal to 1.0% of the amount drawn at closing of the SST VI Mezzanine Loan, and each subsequent draw. Interest on this loan accrued at LIBOR plus 3.0%. The SST VI Mezzanine Loan was amended on December 20, 2022, such amendment increased the principal borrowing amount from a maximum of $45 million to $55 million. Pursuant to this amendment, the interest rate on the SST VI Mezzanine Loan was converted to a variable rate equal to SOFR plus 3.0%. Additionally, in such amendment, SST VI exercised the existing extension option; payments on the SST VI Mezzanine Loan were interest only until the due date of December 30, 2023. As of December 31, 2022 the balance on the SST VI Mezzanine Loan was $35.0 million. On January 31, 2023, SST VI borrowed an additional $15.0 million on the SST VI Mezzanine Loan. On May 2, 2023, SST VI fully repaid the outstanding principal, plus all applicable accrued interest due on the SST VI Mezzanine Loan as of such date for a total amount of approximately $ 51.7 On June 13, 2023 SmartStop OP entered into a promissory note agreement with SST VI OP ( the “SST VI Note”), where SST VI OP borrowed $15.0 million. Interest on the loan accrued at SOFR plus 3.0%. Payments on the SST VI Note are interest only. The loan was extended to December 31, 2024 at the borrower’s option. As such, the interest rate on the loan increased to SOFR plus 4.0%, and a fee equal to 0.25% of the outstanding principal balance was due as a result of SST VI exercising the extension option on December 8, 2023. The SST VI Note required a commitment fee equal to 1.0% of the aggregate principal amount of the loan. On June 28, 2024, the SST VI Note was amended to expand the borrowing capacity up to $25.0 million and extend the maturity date from December 31, 2024 to December 31, 2025. The loan is interest only, and the interest rate on such loan is SOFR plus 4.0%. On July 29, 2024, SST VI borrowed an additional $8.0 million on the SST VI Note. As of September 30, 2024, SST VI OP had $23.0 million borrowed and outstanding pursuant to the SST VI Note. The following table summarizes the carrying value of our investments in and advances to SST VI as of September 30, 2024 and December 31, 2023 (in thousands): Receivables: As of September 30, 2024 As of Receivables and advances due $ 16,660 $ 5,861 Debt: SST VI Note 23,000 15,000 Equity: SST VI OP Units and SST VI SLP 1,126 1,932 SST VI Class C Subordinated Units 4,215 3,307 Total investments in and advances $45,001 $ 26,100 Investments in and advances to SSGT III OP Equity Investments On August 29, 2022, SmartStop OP made an investment of $5.0 million in SS Growth Operating Partnership III, L.P., the operating partnership of SSGT III (“SSGT III OP”), in exchange for common units of limited partnership interest in SSGT III OP. Additionally, a subsidiary of SmartStop OP owns a special limited partnership interest (the “SSGT III SLP”) in SSGT III OP. For the three and nine months ended September 30, 2024, we recorded a loss related to our equity interest in SSGT III OP of approximately $0.1 million and $0.4 million, respectively, and received distributions in the amount of approximately $0.1 million, and $0.2 million, respectively. For the three and nine months ended September 30, 2023, we recorded a loss related to our equity interest in SSGT III OP of approximately $0.2 million and $0.6 million, respectively, and received distributions in the amount of approximately $0.1 million, and $0.2 million, respectively. Debt Investments On August 9, 2022, in connection with SSGT III’s acquisition of two self storage facilities, our Operating Partnership entered into a mezzanine loan agreement with a wholly-owned subsidiary of SSGT III, for up to $50.0 million (the “SSGT III Mezzanine Loan”), of which $42.0 million was funded as an initial draw at the time of closing. The SSGT III Mezzanine Loan requires a commitment fee equal to 1.0% of the amount drawn at closing of the SSGT III Mezzanine Loan, and subsequent draws. The SSGT III Mezzanine Loan was amended on December 20, 2022, such amendment increased the principal borrowing amount from up to $50 million to $77 million. Pursuant to this amendment, the interest rate on the SSGT III Mezzanine Loan became a variable rate equal to SOFR plus 3.0%. Payments on the SSGT III Mezzanine Loan are interest only, and it had an initial maturity date of August 9, 2023. SSGT III extended the ultimate maturity date of the SSGT III Mezzanine Loan until August 9, 2024, as such, the interest rate of the SSGT III Mezzanine Loan increased to SOFR plus 4.0% per annum, pursuant to the December 20, 2022 amendment. The SSGT III Mezzanine Loan may be prepaid in whole or in part at any time without fees or penalty and, in certain circumstances, equity interests securing the SSGT III Mezzanine Loan may be released from the pledge of collateral. The SSGT III Mezzanine Loan is secured by a pledge of the equity interest in the indirect, wholly-owned subsidiaries of SSGT III, that owned seven operating self storage facilities as of September 30, 2024. SSGT III OP, also serves as a non-recourse On May 2, 2024, SSGT III paid down the remaining $1.0 million outstanding on the SSGT III Mezzanine Loan. On August 9, 2024, the SSGT III Mezzanine Loan expired, and no further borrowings were allowed pursuant to such loan agreement. On July 31, 2024, our Operating Partnership provided a bridge loan to an indirect wholly-owned subsidiary of SSGT III for $20.0 million (the “SSGT III Bridge Loan”) to facilitate SSGT III’s acquisition of two self storage facilities. An indirect wholly-owned subsidiary of SSGT III is sponsoring a private offering of beneficial interests in a Delaware statutory trust (“DST”) relating to the two properties. The SSGT III Bridge Loan incurs interest based on adjusted daily simple SOFR plus 300 basis points. The SSGT III Bridge Loan is secured by an indirect pledge of equity in the entity sponsoring the private DST offering relating to the two properties mentioned above, as well as a full guaranty by SSGT III OP. As such sponsor entity sells such DST interests, it is required to utilize such net proceeds to pay down the SSGT III Bridge Loan. SSGT III will be required to pay down at least 15% of the balance within four months, 35% within six months, 55% within nine months, and 75% within twelve months from the final draw. As of September 30, 2024, SSGT III and its subsidiaries had repaid approximately $15.0 million on the SSGT III Bridge Loan, such that $5.0 million was outstanding on such loan as of September 30, 2024.

Note 10. Related Party Transactions Self Administration Transaction On June 28, 2019, we, our Operating Partnership and SmartStop TRS entered into a series of transactions, agreements, and amendments to our existing agreements and arrangements with our then-sponsor, SAM, and SmartStop OP Holdings, LLC (“SS OP Holdings”), a subsidiary of SAM, pursuant to which, effective June 28, 2019, we acquired the self storage advisory, asset management and property management businesses and certain joint venture interests of SAM, along with certain other assets of SAM (collectively, the “Self Administration Transaction”). As a result of the Self Administration Transaction, we became self-managed and succeeded to the advisory, asset management and property management businesses and certain joint ventures previously in place for us, SST IV (until the SST IV Merger Date), and SSGT II (until the SSGT II Merger Date), and we acquired the internal capability to originate, structure and manage additional future self storage investment products which would be sponsored by SmartStop REIT Advisors, LLC (“SRA”), our indirect subsidiary. The transfer agent agreement described below was not impacted by the Self Administration Transaction. Our Chief Executive Officer, who is also the Chairman of our board of directors, holds ownership interests in and is an officer of SAM, and other affiliated entities. Our Chief Executive Officer also previously indirectly held an ownership interest in our former dealer manager. Previously, certain of our executive officers and another member of our board of directors held ownership interests in and/or were officers of SAM, and other affiliated entities. Accordingly, any agreements or transactions we have entered into with such entities may present a conflict of interest. None of SAM and its affiliates or our directors or executive officers receive any compensation, fees or reimbursements from our Managed REITs, other than with respect to fees and reimbursements in accordance with the Administrative Services Agreement and the transfer agent agreement, or as otherwise described in this section. Former Dealer Manager Agreement In connection with our Primary Offering, our Former Dealer Manager received a sales commission of up to 7.0% of gross proceeds from sales of Class A Shares and up to 2.0% of gross proceeds from the sales of Class T Shares in the Primary Offering and a dealer manager fee of up to 3.0% of gross proceeds from sales of both Class A Shares and Class T Shares in the Primary Offering under the terms of the Former Dealer Manager Agreement. In addition, our Former Dealer Manager received an ongoing stockholder servicing fee as discussed in Note 2 – Summary of Significant Accounting Policies – Organization and Offering Costs. Affiliated Former Dealer Manager SAM previously indirectly held a 15% non-voting Transfer Agent Agreement SAM owns 100% of the membership interests of Strategic Transfer Agent Services, LLC, our transfer agent (“Transfer Agent”), which is a registered transfer agent with the SEC. Pursuant to our transfer agent agreement, our Transfer Agent provides transfer agent and registrar services to us. These services are substantially similar to what a third party transfer agent would provide in the ordinary course of performing its functions as a transfer agent, including, but not limited to: providing customer service to our stockholders, processing the distributions and any servicing fees with respect to our shares and issuing regular reports to our stockholder.

We believe that our Transfer Agent, through its knowledge and understanding of the direct participation program industry which includes non-traded Fees paid to our Transfer Agent include a fixed quarterly fee, one-time out-of-pocket The initial term of the transfer agent agreement was three years, which term is automatically renewed for one year successive terms, but either party may terminate the transfer agent agreement upon 90 days’ prior written notice. In the event that we terminate the transfer agent agreement, other than for cause, we will pay our transfer agent all amounts that would have otherwise accrued during the remaining term of the transfer agent agreement; provided, however, that when calculating the remaining months in the term for such purposes, such term is deemed to be a 12 month period starting from the date of the most recent annual anniversary date. Pursuant to the terms of the agreements described above, the following table summarizes related party costs incurred and paid by us for the years ended December 31, 2023 and 2022, as well as any related amounts payable as of December 31, 2023 and 2022.

Accordingly, the advisor and property manager entities of SST IV and SSGT II became our indirect subsidiaries, and we became entitled to receive various fees and expense reimbursements under the terms of the SST IV and SSGT II advisory and property management agreements as described below. In addition, we now also own the advisor and property manager entities of SST VI and SSGT III and are entitled to receive various fees and expense reimbursements under the terms of the SST VI and SSGT III advisory and property management agreements as described below. Advisory Agreement Fees Our indirect subsidiaries, Strategic Storage Advisor IV, LLC, the advisor to SST IV (the “SST IV Advisor”), SS Growth Advisor II, LLC, the advisor to SSGT II (the “SSGT II Advisor”), the SST VI Advisor, and the SSGT III Advisor are or were entitled to receive various fees and expense reimbursements under the terms of the SST IV, SSGT II, SST VI, and SSGT III advisory agreements. SST IV Advisory Agreement The SST IV Advisor provided acquisition and advisory services to SST IV pursuant to an advisory agreement (the “SST IV Advisory Agreement”) with SST IV up until the SST IV Merger on March 17, 2021. Effective March 17, 2021, in connection with the SST IV Merger, the SST IV Advisory Agreement was terminated and none of the aforementioned subordinated distributions or fees were paid. As a result of us acquiring SST IV and terminating such contracts, we recorded a write-off write-off As a result of the Self Administration Transaction, we recorded a deferred tax liability, which was the result of the difference between the GAAP carrying value of the SST IV Advisory Agreement and its carrying value for tax purposes. As we reduced the GAAP carrying value of such intangible asset, as noted above, we adjusted the corresponding value of our related deferred tax liability by approximately $1.4 million during the year ended December 31, 2021, and recorded such benefit to the income tax (expense) benefit line-item in our consolidated statements of operations. SSGT II Advisory Agreement The SSGT II Advisor provided acquisition and advisory services to SSGT II pursuant to an advisory agreement (the “SSGT II Advisory Agreement”) with SSGT II up until the SSGT II Merger on June 1, 2022. Effective June 1, 2022, in connection with the SSGT II Merger, the SSGT II Advisory Agreement was terminated and pursuant to the SSGT II operating partnership agreement, subordinated distribution of approximately $16.1 million was otherwise due. As a result, we recorded a gain of approximately $16.1 million related to our special limited partnership interest and recorded this within gain on preexisting equity interests upon acquisition of control in our consolidated statements of operations. As a result of our acquisition of SSGT II and terminating the SSGT II Advisory Agreement, we recorded a write-off As a result of the Self Administration Transaction, we recorded a deferred tax liability, which was the result of the difference between the GAAP carrying value of the SSGT II Advisory Agreement and its carrying value for tax purposes. As we reduced the GAAP carrying value of such intangible asset, as noted above, we adjusted the corresponding value of our related deferred tax liability by approximately $0.3 million on June 1, 2022, and recorded such benefit to the income tax (expense) benefit line-item in our consolidated statements of operations. SST VI Advisory Agreement The SST VI Advisor provides acquisition and advisory services to SST VI pursuant to an advisory agreement (the “SST VI Advisory Agreement”).

The SST VI Advisory Agreement provides for reimbursement of the SST VI Advisor’s direct and indirect costs of providing administrative and management services to SST VI. Beginning four fiscal quarters after commencement of SST VI’s public offering, which was declared effective March 17, 2022, the SST VI Advisor was required to pay or reimburse SST VI the amount by which SST VI’s aggregate annual operating expenses, as defined, exceed the greater of 2% of SST VI’s average invested assets or 25% of SST VI’s net income, as defined, unless a majority of SST VI’s independent directors determine that such excess expenses were justified based on unusual and non-recurring On March 1, 2022, Pacific Oak Holding Group, LLC, became a 10% non-voting On October 17, 2023, in connection with an amendment to SST VI’s dealer manager agreement, SST VI ceased the sale of Class W shares in its public offering, and subsequently began selling Class Z shares. Separately, we through one of our subsidiaries agreed to pay SST VI’s dealer manager an amount equal to 1.5% of the gross offering proceeds from the sale of Class Z shares sold in their public offering. As such, for the year ended December 31, 2023, we had incurred approximately $5,000 to SST VI’s dealer manager associated with the Class Z Shares sold in their public offering. Additionally, in connection with the commencement of SST VI’s public offering, the SST VI Advisor or its affiliates agreed that it would fund on behalf of SST VI, an amount equal to 1% of the gross offering proceeds from the sale of Class W shares sold in their initial public offering, which amount shall be used by SST VI towards the payment of its offering expenses.

A subsidiary of our Operating Partnership may also be potentially entitled to various subordinated distributions through its ownership of a special limited partnership in SSGT III’s operating partnership agreement if SSGT III (1) lists its shares of common stock on a national exchange, (2) terminates the SSGT III Advisory Agreement, (3) liquidates its portfolio, or (4) merges with another entity or enters into an Extraordinary Transaction, as defined in the SSGT III operating partnership agreement. The SSGT III Advisory Agreement provides for reimbursement of the SSGT III Advisor’s direct and indirect costs of providing administrative and management services to SSGT III. Managed REIT Property Management Agreements Our indirect subsidiaries, Strategic Storage Property Management IV, LLC, SS Growth Property Management II, LLC, Strategic Storage Property Management VI, LLC, and SS Growth Property Management III, LLC, (collectively the “Managed REITs Property Managers”), are or were entitled to receive fees for their services in managing the properties owned by the Managed REITs pursuant to property management agreements entered into between the owner of the property and the applicable Managed REIT’s Property Manager.

As a result of us acquiring SSGT II and terminating such contracts, we recorded a write-off In connection with the Self Administration Transaction, we previously recorded a deferred tax liability, which was the result of the difference between the GAAP carrying value of the SST IV and SSGT II property management contracts and their carrying values for tax purposes. As we reduced the GAAP carrying value of such intangible assets, we adjusted the value of our deferred tax liability on a pro-rata Summary of Fees and Revenue Related to the Managed REITs Pursuant to the terms of the various agreements described above for the Managed REITs, the following summarizes the related party fees for the years ended December 31, 2023, 2022, and 2021: Managed REIT Platform Revenues Year Ended Year Ended Year Ended Asset Management Fees: SST IV (1) $ —  $ —  $ 716,278 SSGT II (2) —  798,395 1,843,769 SST VI 3,420,040 1,348,314 178,282 SSGT III 1,017,194 145,622 —  4,437,234 2,292,331 2,738,329 Property Management Fees: SST IV (1) —  —  346,179 SSGT II (2) —  407,706 709,533 SST VI 1,243,056 551,493 99,602 SSGT III 358,494 62,426 —  JV Properties 738,408 432,944 116,984 2,339,958 1,454,569 1,272,298 Tenant Protection Program Fees: SST IV (1) —  —  285,959 SSGT II (2) —  250,156 636,671 SST VI 841,582 396,758 158,662 SSGT III 186,109 8,119 —  JV Properties 271,221 186,658 51,185 1,298,912 841,691 1,132,477 Acquisition Fees: SST VI 2,470,497 1,846,168 649,623 SSGT III 837,000 846,000 —  3,307,497 2,692,168 649,623 Other Managed REIT Fees (3) 556,353 538,457 530,243 Managed REIT Platform Fees 11,939,954 7,819,216 6,322,970 Sponsor funding reduction (4) (33,643 ) —  —  Total Managed REIT Platform Revenues $ 11,906,311 $ 7,819,216 $ 6,322,970 (1) On March 17, 2021, we acquired SST IV and no longer earn such fees. Additionally, the Tenant Protection Program revenue for SST IV is now included in ancillary operating revenue in our consolidated statements of operations. (2) On June 1, 2022, we acquired SSGT II and no longer earn such fees. Additionally, the Tenant Protection Program revenue for SSGT II is now included in ancillary operating revenue in our consolidated statements of operations. (3) Such revenue primarily includes other property management related fees, construction management fees, development fees, and other miscellaneous revenues. (4) Pursuant to the Sponsor Funding Agreement, SmartStop funds certain costs of SST VI’s share sales, and in return receives Series C Units in SST VI’s OP. The excess of the funding over the value of the Series C Units received is accounted for as a reduction of Managed REIT Platform revenues from SST VI over the remaining estimated term of the management contracts with SST VI. We offer tenant insurance or tenant protection programs to customers at our Managed REITs’ properties pursuant to which we, as the property manager and majority shareholder of the Tenant Protection Program joint ventures, are entitled to substantially all of the net revenue attributable to the sale of such tenant programs. In order to protect our interest in receiving these revenues in light of the fact that the Managed REITs control the properties, we and the Managed REITs transferred our respective rights in such arrangements to a joint venture entity owned 99.9% by us through a TRS subsidiary and 0.1% by the Managed REIT. Under the terms of the operating agreements of the joint venture entities, we receive 99.9% of the net revenues generated from such Tenant Protection Programs and the Managed REIT receives the other 0.1% of such net revenues. Subsequent to the SST IV Merger and the SSGT II Merger, the SST IV and SSGT II Tenant Protection Programs joint ventures are wholly-owned by us and such revenue is generated at our now wholly-owned self storage properties and is recorded within ancillary operating revenue in our consolidated statements of operations. Reimbursable costs from Managed REITs includes reimbursement of SST IV (until the SST IV Merger Date), SSGT II, (until the SSGT II Merger Date), SST VI and SSGT III’s Advisors’ direct and indirect costs of providing administrative and management services to the Managed REITs. Additionally, reimbursable costs includes reimbursement pursuant to the property management agreements for reimbursement of the costs of managing the Managed REITs’ properties, including wages and salaries and other expenses of employees engaged in operating, managing and maintaining such properties. As of December 31, 2023 and 2022, we had receivables due from the Managed REITs totaling approximately $6.5 million, and $2.0 million, respectively. Such amounts are included in investments in and advances to the Managed REITs line-item in our consolidated balance sheets. Such amounts included unpaid amounts relative to the above table, in addition to other direct routine reimbursable expenditures of the Managed REITs that we directly funded. Investments in and advances to SST VI OP Equity Investments On March 10, 2021, SmartStop OP made an investment of $5.0 million in SST VI OP, in exchange for common units of limited partnership interest in SST VI OP. Additionally, a subsidiary of SmartStop OP owns a special limited partnership interest (the “SST VI SLP”) in SST VI OP. For the years ended December 31, 2023 and 2022, we recorded a loss related to our equity interest, excluding our preferred investment discussed below, in SST VI OP of approximately $0.9 million and $1.8 million, respectively, and received distributions in the amount of approximately $341,000 and $315,000, respectively. On January 30, 2023, a subsidiary of SmartStop made a preferred investment of 600,000 Series A Cumulative Redeemable Preferred units of limited partnership interest in SST VI OP for an aggregate of $15 million. Upon closing of the preferred investment, an investment fee equal to 1% of the investment amount was owed and paid by SST VI OP. SmartStop, through its subsidiary, received distributions, payable monthly in arrears, at a rate of 7.0% per annum from the date of issuance until the second anniversary of the date of issuance, 8.0% per annum commencing thereafter until the third anniversary of the date of issuance, 9.0% per annum commencing thereafter until the fourth anniversary of the date of issuance, and 10% per annum thereafter, payable monthly. On May 2, 2023, SST VI fully redeemed SmartStop’s preferred investment of 600,000 Series A Cumulative Redeemable Preferred units of limited partnership interest in SST VI OP, and repaid accrued distributions due as of the date of redemption for a total amount of approximately $15.1 million. As discussed in Note 2 – Summary of Significant Accounting Policies, due to our equity interest in SST VI OP, we consolidated this investment from March 10, 2021 (the date of our initial investment in SST VI OP) until May 1, 2021. Sponsor Funding Agreement On November 1, 2023, SRA, a subsidiary of SmartStop OP entered into a Sponsor Funding Agreement with SST VI and SST VI OP, in connection with certain changes to the public offering of SST VI. Pursuant to the Sponsor Funding Agreement, SRA, as sponsor of the SST VI offering, has agreed to fund the payment of (i) the upfront 3% sales commission for the sale of shares of SST VI’s Class Y common stock sold in the SST VI offering, (ii) the upfront 3% dealer manager fee for the Class Y Shares sold in the SST VI offering, and (iii) the estimated 1% organization and offering expenses for the sale of Class Y Shares and shares of SST VI’s Class Z common stock sold in the SST VI offering. SRA also agreed to reimburse SST VI in cash to cover the dilution from certain one-time stock dividends which were issued by SST VI to existing stockholders in connection with the sponsor funding changes to the SST VI offering. On December 15, 2023, we paid SST VI approximately $6.6 million for the reimbursement of the aforementioned stock dividend. In consideration for SRA providing the funding for the front-end sales load and the cash to cover the dilution from the stock dividends described above, SST VI OP will issue a number of Series C Units to SRA equal to the dollar amount of such funding divided by the then-current offering price for the Class Y Shares and Class Z Shares sold in the SST VI offering, which will initially be $9.30 per share. Pursuant to the Sponsor Funding Agreement, SRA will reimburse SST VI monthly for the applicable front-end sales load it has agreed to fund, and SST VI OP will issue the Series C Units on a monthly basis upon such reimbursement. The Sponsor Funding Agreement will terminate immediately upon the date that SST VI ceases to offer the Class Y Shares and Class Z Shares in the SST VI offering. The SST VI offering was set to expire on March 17, 2024, and was extended to March 17, 2025 upon the approval of SST VI’s board of directors on February 1, 2024. Inclusive of all extension options available to SST VI, their offering could not extend beyond September 12, 2025. On November 1, 2023, SRA entered into Amendment No. 3 to the Second Amended and Restated Limited Partnership Agreement of SST VI OP with SST VI and SST VI OP containing, among other things, the terms of the Series C Units. The Series C Units shall initially have no distribution, liquidation, voting, or other rights to participate in SST VI OP unless and until such Series C Units are converted into class A units of SST VI OP. The Series C Units shall automatically convert into class A units on a one-to-one basis upon SST VI’s disclosure of an estimated net asset value per share equal to at least $10.00 per share for each class of SST VI shares of common stock, including the Class Y Shares and Class Z Shares, calculated net of the value of the Series C Units to be converted. Through December 31, 2023, we have paid SST VI approximately $6.6 million in connection with the Sponsor Funding Agreement, and have received approximately 710,000 subordinated units. Additionally, as of December 31, 2023, approximately $0.2 million was accrued as a payable pursuant to the Sponsor Funding Agreement. If SST VI were to sell the maximum amount under its offering of $1.0 billion, assuming the sale of all Class Y Shares consisting of a 7% front end sales load, the maximum commitment of SRA pursuant to the Sponsor Funding Agreement is approximately $70 million, excluding the reimbursement for the one time stock dividend of approximately $6.6 million. Debt Investments On March 11, 2021, SST VI OP, through a wholly-owned subsidiary, used the funds from our $5.0 million investment described above, in part, to acquire its first self storage facility in Phoenix, Arizona for approximately $16 million. In connection with SST VI OP’s acquisition of the Phoenix property, we provided a $3.5 million mezzanine loan to a wholly-owned subsidiary of SST VI OP with an initial interest rate of 8.5% and term of six months; as well as a 180 day extension option which was exercised and increased the interest rate to 9.25% for the remainder of the term. On April 16, 2021, in connection with SST VI OP’s investment in a real estate joint venture property located in North York, Ontario Canada, we provided a $2.1 million term loan with similar terms as the mezzanine loan discussed above. On November 12, 2021, a wholly-owned subsidiary of SST VI OP repaid the outstanding balance on the $3.5 million mezzanine loan and the $2.1 million term loan along with all accrued interest. The loans were terminated in accordance with the mezzanine loan agreement and the term loan agreement without fees or penalties. On December 30, 2021, in connection with SST VI’s acquisition of two self storage facilities, SmartStop OP entered into a mezzanine loan agreement with a wholly-owned subsidiary of SST VI OP for up to $45 million (the “SST VI Mezzanine Loan”). The SST VI Mezzanine Loan required a commitment fee equal to 1.0% of the amount drawn at closing of the SST VI Mezzanine Loan, and each subsequent draw. Interest on this loan accrued at LIBOR plus 3.0%. The SST VI Mezzanine Loan was amended on December 20, 2022, such amendment increased the principal borrowing amount from a maximum of $45 million to $55 million. Pursuant to this amendment, the interest rate on the SST VI Mezzanine Loan was converted to a variable rate equal to SOFR plus 3.0%. Additionally, in such amendment, SST VI exercised the existing extension option; payments on the SST VI Mezzanine Loan were interest only until the due date of December 30, 2023. As of December 31, 2022, a wholly-owned subsidiary of SST VI OP had $35.0 million outstanding, pursuant to the SST VI Mezzanine Loan. On May 2, 2023, SST VI fully repaid the outstanding principal, plus all applicable accrued interest due on the SST VI Mezzanine Loan as of such date for a total amount of approximately $51.7 million. On such date, the SST VI Mezzanine Loan agreement was terminated. On June 13, 2023 SmartStop OP entered into a promissory note agreement with SST VI OP ( the “SST VI Note”), where SST VI OP borrowed $15.0 million. Interest on the loan accrued at SOFR plus 3.0%. Payments on the SST VI Note are interest only. The loan was extended to December 31, 2024 at the borrower’s option. As such, the interest rate on the loan increased to SOFR plus 4.0%, and a fee equal to 0.25% of the outstanding principal balance was due as a result of SST VI exercising the extension option. The SST VI Note required a commitment fee equal to 1.0% of the aggregate principal amount of the loan. As of December 31, 2023, SST VI OP had $15.0 million borrowed and outstanding pursuant to the SST VI Note.

The SSGT III Mezzanine Loan requires a commitment fee equal to 1.0% of the amount drawn at closing of the SSGT III Mezzanine Loan, and subsequent draws. The SSGT III Mezzanine Loan was amended on December 20, 2022, such amendment increased the principal borrowing amount from up to $50 million to $77 million. Pursuant to this amendment, the interest rate on the SSGT III Mezzanine Loan became a variable rate equal to SOFR plus 3.0%.

Share-Based Payment Arrangement [Abstract]
Equity Based Compensation	Note 11. Equity Based Compensation Prior to June 15, 2022, we issued equity based compensation pursuant to the Company’s Employee and Director Long-Term Incentive Plan (the “Prior Plan”). On June 15, 2022, our stockholders approved the 2022 Long-Term Incentive Plan (the “Plan”) and we no longer issue equity under the Prior Plan. Pursuant to the Plan, we are able to issue various forms of equity based compensation. Through September 30, 2024, we have generally issued equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”). The fair value of restricted stock is determined on the grant date based on an estimated value per share. The estimated fair value of our restricted stock was determined with the assistance of third party valuation specialists primarily based on an income approach to value our properties as well as the Managed REIT Platform, less the estimated fair value of our debt and other liabilities. The key assumptions used in estimating the fair value of our restricted stock were projected annual net operating income, projected growth rates, discount rates, capitalization rates and an illiquidity discount. The fair value of LTIP Units were further adjusted by applying an additional discount as the LTIP Units are not initially economically equivalent to our restricted stock. For performance based awards, a fair value was determined for each performance ranking scenario, with stock compensation expense recorded using the fair value of the scenario determined to be probable of achievement as of the end of the respective period. Time Based Awards We have granted various time based awards, which generally vest ratably over either one three With respect to grants of time based LTIP Units, distributions accrue based on the effective date of each grant, and are payable as distributions are paid on our Class A Shares without regard to whether the underlying awards have vested. With respect to time based restricted stock issued to our board of directors, distributions accrue as of the effective date of each grant and are payable as distributions are paid on our Class A Shares without regard to whether the underlying awards have vested. With respect to all other existing time based restricted stock, distributions accrue on non-vested Holders of time based LTIP Units receive allocations of profits and losses with respect to the LTIP Units as of the effective date, distributions from the effective date in an amount equivalent to the distributions declared and paid on our Class A Shares, and the same voting rights as holders of common units, voting as a class with each LTIP Unit holder having one vote per LTIP Unit held. Prior to vesting, time based LTIP Units generally may not be transferred, other than by laws of descent and distribution.

The targeted award for each executive was determined and approved by the Compensation Committee of our board of directors. The actual number of shares of restricted stock or LTIP Units, as applicable, to be issued upon vesting may range from 0% to 200% of the targeted award, such determination being based upon the results of the performance measure. Performance based awards vest based upon our performance as ranked amongst a peer group of self storage related companies. This comparison is conducted using a performance measure of average annual same-store revenue growth, analyzed over a three-year period. Earned awards for the 2022, 2023 and 2024 grants will vest, as applicable, no later than March 31, 2025, 2026 2027 Recipients of performance based restricted stock accrue distributions during the performance period, and such distributions will only be payable on the date that any such shares of restricted stock vest, based upon the performance level attained. Recipients of performance based LTIP Units are issued LTIP Units at 200% of the targeted award and are entitled to receive distributions and allocations of profits and losses with respect to the performance based LTIP Units as of the effective date of each award in an amount equal to 10% of the distributions and allocations available to such LTIP Units, until the Distribution Participation Date (as defined in the Operating Partnership Agreement). The remaining 90% of distributions will accrue and will be payable on the Distribution Participation Date based upon the performance level attained and number of performance based LTIP Units that vest. Following the Distribution Participation Date, recipients will be entitled to receive the full amount of distributions and allocations of profits and losses with respect to the vested performance-based LTIP Units, such amount being equivalent to distributions declared and paid on our Class A Shares.

Accordingly, individuals who elected to receive performance based restricted stock were issued and immediately vested additional shares to equal 200% of their targeted award. Holders of performance based restricted stock do not have any rights as a stockholder with respect to the unvested portion of such restricted stock awards. Prior to vesting, shares of performance based restricted stock generally may not be transferred, other than by laws of descent and distribution. Holders of performance based LTIP Units have the same voting rights as holders of common units, voting as a class with each LTIP Unit holder having one vote per LTIP Unit held. Prior to vesting, performance based LTIP Units generally may not be transferred, other than by laws of descent and distribution. LTIP Units are designed to qualify as “profits interests” in the Operating Partnership for federal income tax purposes. The profits interests’ characteristics of the LTIP Units mean that initially they will not be treated as economically equivalent in value to a common unit and the issuance of LTIP Units will not be a taxable event to the Operating Partnership or the recipient. If and when certain events occur pursuant to applicable tax regulations and in accordance with the Operating Partnership Agreement, LTIP Units may become economically equivalent to common units of limited partnership interest of our Operating Partnership on a one-for-one As of September 30, 2024, 8,769,928 shares of stock were available for issuance under the Plan. We recorded approximately $1.3 million and $3.7 million of equity based compensation expense in general and administrative expense during the three and nine months ended September 30, 2024, respectively, compared to approximately $1.3 million and $3.7 million during the three and nine months ended September 30, 2023, respectively. We recorded approximately $0.1 million and $0.2 million of equity based compensation expense in property operating expenses, within our consolidated statements of operations for the three and nine months ended September 30, 2024, respectively, compared to approximately $0.1 million and $0.4 million during the three and nine months ended September 30, 2023, respectively. As of September 30, 2024, there was approximately $9.3 million of total unrecognized compensation expense related to non-vested period of approximately 2.3 years. As of December 31, 2023, there was approximately $6.8 million of total unrecognized compensation expense related to non-vested In March 2024, an aggregate of 270,096 LTIP Units were issued to our executive officers in connection with performance-based equity grants. With respect to performance-based equity grants, the number of LTIP Units granted as of the grant date was equal 200% of the targeted award. Similarly, in March 2024, an aggregate of 274,183 LTIP Units were issued to our executive officers in connection with time-based equity grants. These are non-vested grants which shall vest ratably over four years, with the first tranche vesting on December 31, 2024, subject to the recipient’s continued employment through the applicable vesting date.	Note 11. Equity Based Compensation Prior to June 15, 2022, we issued equity based compensation pursuant to the Company’s Employee and Director Long-Term Incentive Plan (the “Prior Plan”). On June 15, 2022, our stockholders approved the 2022 Long-Term Incentive Plan (the “Plan”) and we no longer issue equity under the Prior Plan. Pursuant to the Plan, we are able to issue various forms of equity based compensation. Through December 31, 2023, we have generally issued equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”). Through March 2020, we had only issued restricted stock, which shares are subject to a time based vesting period. In April 2020, the Compensation Committee of the board of directors approved awards for our executive officers, which include (1) performance based awards, and (2) time based awards. For both such type of awards, the recipient can choose either LTIP Units or restricted stock consisting of shares of our common stock. Effective June 2022, certain other recipients of time based awards were also allowed to choose either LTIP Units or restricted stock shares of our common stock. The fair value of restricted stock is determined on the grant date based on an estimated value per share. The estimated fair value of our restricted stock was determined with the assistance of third party valuation specialists primarily based on an income approach to value our properties as well as the Managed REIT Platform, l ess the estimated fair value of our debt and other liabilities. The key assumptions used in estimating the fair value of our restricted stock were projected annual net operating income, projected growth rates, discount rates, capitalization rates and an illiquidity discount. The fair value of LTIP Units were further adjusted by applying an additional discount as the LTIP Units ar Time Based Awards We have granted various time based awards, which generally vest ratably over either one three With respect to grants of time based LTIP Units, distributions accrue based on the effective date of each grant, and are payable as distributions are paid on our Class A Shares without regard to whether the underlying awards have vested. With respect to time based restricted stock issued to our board of directors in or after June 2022, distributions accrue as of the effective date of each grant and are payable as distributions are paid on our Class A Shares without regard to whether the underlying awards have vested. With respect to all other existing time based restricted stock, distributions accrue on non-vested Holders of time based LTIP Units receive allocations of profits and losses with respect to the LTIP Units as of the effective date, distributions from the effective date in an amount equivalent to the distributions declared and paid on our Class A Shares, and the same voting rights as holders of common units, voting as a class with each LTIP Unit holder having one vote per LTIP Unit held.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 12. Commitments and Contingencies Distribution Reinvestment Plan We have adopted an amended and restated distribution reinvestment plan (our “DRP”) that allows both our Class A and Class T stockholders to have distributions otherwise distributable to them invested in additional Class A Shares and Class T Shares, respectively. Under our DRP, the board of directors may amend, modify, suspend or terminate our plan for any reason upon 10 days’ written notice to the participants. The purchase price per share pursuant to our DRP is equivalent to the estimated value per share approved by our board of directors and in effect on the date of purchase of shares under the plan. In conjunction with the board of directors’ declaration of a new estimated value per share of our common stock on January 15, 2024, any shares sold pursuant to our distribution reinvestment plan will be sold at our new estimated value per share of $15.25 per Class A Share and Class T Share. Please see the section below titled “Suspension and Partial Resumption of DRP and SRP” for additional information. As of September 30, 2024, we had sold approximately 10.3 million Class A Shares and approximately 1.3 million Class T Shares through our distribution reinvestment plan, of which, approximately 0.5 million Class A Shares and approximately 0.1 million Class T Shares were sold under our current DRP Offering. The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. Share Redemption Program As described in “Note 2 – Summary of Significant Accounting Policies – Redeemable Common Stock,” we have an SRP. Please refer to that section for additional details. Pursuant to the SRP, we may redeem the shares of stock presented for redemption for cash to the extent that such requests comply with the below terms of our SRP and we have sufficient funds available to fund such redemption. All redemption requests received, and not withdrawn, on or prior to the last day of the applicable quarter are processed on the last business day of the month following the end of the quarter in which the redemption requests were received. Our board of directors may amend, suspend or terminate the SRP with 30 days’ notice to our stockholders. We may provide this notice by including such information in a Current Report on Form 8-K On August 20, 2020, our board of directors amended the terms of the SRP to revise the redemption price per share for all redemptions under the SRP to be equal to the most recently published estimated net asset value per share of the applicable share class (the “SRP Amendment”). Prior to the SRP Amendment, the redemption amount was the lesser of the amount the stockholders paid for their shares or the price per share in the current offering. On January 15, 2024, we declared a new estimated net asset value per share and the redemption price under our SRP immediately changed to $15.25 (our current estimated net asset value per share). There are several limitations in addition to those noted above on our ability to redeem shares under the SRP including, but not limited to: • During any calendar year, we will not redeem in excess of 5% of the weighted-average number of shares outstanding during the prior calendar year. • The amount available for redemption is limited to the proceeds from the sale of shares pursuant to our distribution reinvestment plan, less any prior redemptions. • We have no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland law, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency. During the nine months ended September 30, 2024, approximately 2.0 million shares or $29.9 million of requests that met the eligibility criteria were requested to be redeemed; approximately $17.3 million of which were fulfilled during the nine months ended September 30, 2024, and approximately $12.6 million of which were included in accounts payable and accrued liabilities within our consolidated balance sheets as of September 30, 2024 and fulfilled in October 2024. During the year ended December 31, 2023, approximately 1.5 million shares or $22.9 million of requests that met the eligibility criteria were requested to be redeemed; approximately $19.0 million of which were fulfilled during the year ended December 31, 2023, and approximately $3.9 million of which were included in accounts payable and accrued liabilities within our consolidated balance sheets as of December 31, 2023 and fulfilled in January 2024. Please see the section below titled “Suspension and Partial Resumption of DRP and SRP” for additional information. Suspension and Partial Resumption of DRP and SRP In connection with a review of liquidity alternatives by the board of directors, on March 7, 2022, the board of directors approved the full suspension of our DRP and SRP. However, on March 16, 2023, the DRP was fully reinstated and the SRP was partially reinstated to allow for redemptions solely sought in connection with a stockholder’s death, “qualifying disability” (as that term is defined in the SRP), confinement to a long-term care facility, or other exigent circumstances. All other redemptions remain suspended at this time. On May 1, 2024, our board of directors adopted a limitation to our SRP such that any redemption request made under the SRP in connection with a stockholder’s death must be made within one year of the date of such death in order to be honored by us. This limitation took effect on June 1, 2024. Operating Partnership Redemption Rights Generally, the limited partners of our Operating Partnership have the right to cause our Operating Partnership to redeem their limited partnership units for cash equal to the value of an equivalent number of our shares, or, at our option, we may purchase their limited partnership units by issuing one share of our common stock for each limited partnership unit redeemed. These rights may not be exercised under certain circumstances that could cause us to lose our REIT election. Furthermore, limited partners may exercise their redemption rights only after their limited partnership units have been outstanding for one year. Additionally, the Class A-1 Class A-1 Other Contingencies and Commitments We have severance arrangements which cover certain members of our management team; these provide for severance payments upon certain events, including after a change of control. See Note 10 – Related Party Transactions related to our debt investments in the Managed REITs and our Sponsor Funding Agreement with SST VI for more information about our contingent obligations under these agreements. As of September 30, 2024, pursuant to various contractual relationships, we are required to make other payments in the amounts of approximately $3.0 million, $11.2 million, $4.2 million, and $3.9 million during the years ending December 31, 2024, 2025, 2026, and 2027, respectively. From time to time, we are party to legal, regulatory and other proceedings that arise in the ordinary course of our business. In accordance with applicable accounting guidance, management accrues an estimated liability 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. For such proceedings, we are not aware of any for which the outcome is reasonably likely to have a material adverse effect on our results of operations or financial condition.	Note 12.

On March 29, 2022, 1,094,434 Class A-2 Class A-1 Class A-2 Class A-1 On August 9, 2022, pursuant to the revised definition of AUM as described above, we reached the incremental assets under management threshold of $700 million, and 1,094,434 Class A-2 Class A-1 Class A-2 Class A-1 Distribution Reinvestment Plan We have adopted an amended and restated distribution reinvestment plan (our “DRP”) that allows both our Class A and Class T stockholders to have distributions otherwise distributable to them invested in additional shares of our Class A and Class T Shares, respectively. Under our DRP, the Board may amend, modify, suspend, or terminate our plan for any reason upon 10 days’ written notice to the participants. The purchase price per share pursuant to our DRP is equivalent to the estimated value per share approved by our board of directors and in effect on the date of purchase of shares under the plan. In conjunction with the board of directors’ declaration of a new estimated value per share of our common stock on January 15, 2024, any shares sold pursuant to our distribution reinvestment plan will be sold at our new estimated value per share of $15.25 per Class A Share and Class T Share. Please see the section below titled “Suspension and Partial Resumption of DRP and SRP” for additional information. As of December 31, 2023, we had sold approximately 8.2 million Class A Shares and approximately 1.1 million Class T Shares through our DRP Offering. Share Redemption Program As described in Note 2 – Summary of Significant Accounting Policies- Redeemable Common Stock, we have an SRP. Please refer to that section for additional details. Pursuant to the SRP, we may redeem the shares of stock presented for redemption for cash to the extent that such requests comply with the below terms of our SRP and we have sufficient funds available to fund such redemption. All redemption requests received, and not withdrawn, on or prior to the last day of the applicable quarter are processed on the last business day of the month following the end of the quarter in which the redemption requests were received. Our board of directors may amend, suspend or terminate the SRP with 30 days’ notice to our stockholders. We may provide this notice by including such information in a Current Report on Form 8-K On August 20, 2020, our board of directors amended the terms of the SRP to revise the redemption price per share for all redemptions under the SRP to be equal to the most recently published estimated net asset value per share of the applicable share class (the “SRP Amendment”). Prior to the SRP Amendment, the redemption amount was the lesser of the amount the stockholders paid for their shares or the price per share in the current offering. On January 15, 2024, we declared a new estimated net asset value per share and the redemption price under our SRP immediately changed to $15.25 (our current estimated net asset value per share). There are several limitations in addition to those noted above on our ability to redeem shares under the SRP including, but not limited to: • During any calendar year, we will not redeem in excess of 5% of the weighted-average number of shares outstanding during the prior calendar year. • The amount available for redemption is limited to the proceeds from the sale of shares pursuant to our distribution reinvestment plan, less any prior redemptions. • We have no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland law, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency. During the year ended December 31, 2023, approximately 1.5 million shares or $22.9 million of requests that met the eligibility criteria were requested to be redeemed; approximately $19.0 million of which were fulfilled during the year ended December 31, 2023, and approximately $3.9 million of which were included in accounts payable and accrued liabilities within our consolidated balance sheets as of December 31, 2023 and fulfilled in January 2024. For the year ended December 31, 2022, we received redemption requests totaling approximately $2.4 million (approximately 0.2 million shares). Due to the complete suspension of our SRP at such time we were unable to honor redemption requests made during the year ended December 31, 2022. For the year ended December 31, 2021, we received redemption requests totaling approximately $5.6 million (approximately 0.4 million shares), approximately $3.9 million of which were fulfilled during the year ended December 31, 2021, with the remaining approximately $1.7 million included in accounts payable and accrued liabilities as of December 31, 2021 and fulfilled in January 2022. Please see the section below titled “Suspension and Partial Resumption of DRP and SRP” for additional information. Suspension and Partial Resumption of DRP and SRP In connection with a review of liquidity alternatives by the Board, on March 7, 2022, the Board approved the full suspension of our DRP and SRP. However, on March 16, 2023, the DRP was fully reinstated and the SRP was partially reinstated to allow for redemptions solely sought in connection with a stockholder’s death, “qualifying disability” (as that term is defined in the SRP), confinement to a long-term care facility, or other exigent circumstances. All other redemptions remain suspended at this time. All previously received and reconfirmed redemption requests, along with such requests received during the three months ended March 31, 2023 that correctly met the eligibility criteria above, were redeemed in April 2023, in accordance with the SRP. For those stockholders that had elected to participate in the DRP prior to its suspension in March 2022, distributions automatically reverted back to being reinvested through the DRP effective for the month of March 2023 (to the extent we are qualified to offer shares pursuant to the DRP in accordance with applicable state laws). Operating Partnership Redemption Rights Generally, the limited partners of our Operating Partnership, have the right to cause our Operating Partnership to redeem their limited partnership units for cash equal to the value of an equivalent number of our shares, or, at our option, we may purchase their limited partnership units by issuing one share of our common stock for each limited partnership unit redeemed. These rights may not be exercised under certain circumstances that could cause us to lose our REIT election. Furthermore, limited partners may exercise their redemption rights only after their limited partnership units have been outstanding for one year. Additionally, the Class A-1 Class A-1 Other Contingencies and Commitments We have severance arrangements which cover certain members of our management team; these provide for severance payments upon certain events, including after a change of control. See Note 10 – Related Party Transactions related to our debt investments in the Managed REITs and our Sponsor Funding Agreement with SST VI for more information about our contingent obligations under these agreements. As of December 31, 2023, pursuant to various contractual relationships, we are required to make other non-cancellable From time to time, we are party to legal, regulatory and other proceedings that arise in the ordinary course of our business. In accordance with applicable accounting guidance, management accrues an estimated liability 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. For such proceedings, we are not aware of any for which the outcome is reasonably likely to have a material adverse effect on our results of operations or financial condition. In connection with a fire that occurred at one of our properties, a neighboring property was also damaged. In December 2023, we, along with our insurance carrier, received a subrogation demand letter from an attorney representing the insurance company for the neighboring property owner for approximately $8.3 million alleging that we were responsible for their damages. We intend to vigorously defend this matter. We believe we have adequate insurance coverage for this matter.

Subsequent Events [Abstract]
Subsequent Events	Note 14. Subsequent Events There are no significant events which have occurred subsequent to September 30, 2024, other than the subsequent events discussed elsewhere in the notes to the financial statements.	Note 14. Subsequent Events In addition to the subsequent events discussed elsewhere in the notes to the financial statements, the following events occurred subsequent to December 31, 2023: Issuance of Equity Award Subsequent to December 31, 2023, the compensation committee of our board of directors approved the 2024 executive compensation terms for our executives, which included (1) performance-based equity grants in the form of either, at the election of the executive, restricted stock awards or LTIP Units, and (2) time-based equity grants in the form of either, at the election of the executive, restricted stock awards or LTIP Units. In March 2024, an aggregate of 270,096 LTIP Units were issued to our executive officers in connection with performance-based equity grants. With respect to performance-based equity grants, the number of LTIP Units granted as of the grant date was equal 200% of the targeted award. These are non-vested Similarly, in March 2024, an aggregate of 274,183 LTIP Units were issued to our executive officers in connection with time-based equity grants. These are non-vested 2024 Credit Facility On February 22, 2024, we through our Operating Partnership (the “Borrower”), entered into an amended and restated revolving credit facility with KeyBank, National Association, as administrative agent and collateral agent, certain others listed as joint book runners, joint lead arrangers, syndication agents and documentation agents, and certain other lenders party thereto. The 2024 Credit Facility replaces the credit facility the Company entered into on March 17, 2021, and has a maturity date of February 22, 2027. The aggregate amount of the 2024 Credit Facility is $650 million. The Borrower has the right to increase the amount available under the 2024 Credit Facility by an additional $850 million, for a total potential maximum aggregate amount of $1.5 billion, subject to certain conditions. The 2024 Credit Facility also includes sublimits of (a) up to $25 million for letters of credit and (b) up to $25 million for swingline loans; each of these sublimits are part of, and not in addition to, the amounts available under the 2024 Credit Facility. Borrowings under the 2024 Credit Facility may be in either U.S. dollars or Canadian dollars. Upon the closing of the 2024 Credit Facility, we immediately drew down an aggregate amount of $ million, which was used primarily to pay off the amounts outstanding under the Credit Facility. The maturity date of the 2024 Credit Facility is February 22, 2027, subject to a one-year extension option, subject to the payment of an extension fee of 0.20% on the aggregate amount of the then-outstanding revolving commitments for such extension, and it may be prepaid or terminated at any time without penalty; provided, however, that the lenders shall be indemnified for certain breakage costs. Amounts borrowed under the 2024 Credit Facility bear interest based on the type of borrowing (either Base Rate Loans, Daily Simple SOFR Loans, Term SOFR Loans or CORRA Loans, each as defined in the 2024 Credit Facility). Base Rate Loans bear interest at the lesser of (x) the Base Rate (as defined in the 2024 Credit Facility) plus the applicable rate, or (y) the maximum rate. Daily Simple SOFR Loans bear interest at the lesser of (a) Adjusted Daily Simple SOFR (as defined in the 2024 Credit Facility) plus the applicable rate, or (b) the maximum rate. Term SOFR Loans bear interest at the lesser of (a) Term SOFR (as defined in the 2024 Credit Facility) for the interest period in effect plus the applicable rate, or (b) the maximum rate. CORRA Loans bear interest at the lesser of (a) Adjusted Daily Simple CORRA (as defined in the 2024 Credit Facility) plus the applicable rate, or (b) the maximum rate. The corresponding applicable rate varies between (i) prior to a Security Interest Termination Event (defined below), 165 basis points to 230 basis points for Daily Simple SOFR Loans, Term SOFR Loans and CORRA Loans and between 65 basis points and 130 basis points for Base Rate Loans, in each case of this clause (i), depending on the consolidated leverage ratio of the Company and (ii) following a Security Interest Termination Event, 140 basis points to 225 basis points for Daily Simple SOFR Loans, Term SOFR Loans and CORRA Loans and between 40 basis points and 125 basis points for Base Rate Loans, in each case of this clause (ii), depending on the consolidated capitalization rate leverage ratio of the Company. Initial advances under the 2024 Credit Facility are Daily Simple SOFR Loans that bear interest at 175 basis points over Adjusted Daily Simple SOFR. The 2024 Credit Facility is also subject to an annual unused fee based upon the average amount of the unused portion of the 2024 Credit Facility, which varies from 15 bps to 25 bps, depending on the size of the unused amount, as well as whether a Security Interest Termination Event has occurred. The 2024 Credit Facility is fully recourse, jointly and severally, to us, the Borrower, and certain of our subsidiaries (the “Subsidiary Guarantors”). In connection with the 2024 Credit Facility, we, the Borrower and the Subsidiary Guarantors executed guarantees in favor of the lenders. It is an event of default under the 2024 Credit Facility if (a) there is a payment default by us, the Borrower or any Subsidiary Guarantor under any recourse debt for borrowed money, (b) there is a payment default by us or any of its subsidiaries under any non-recourse debt of at least $75 million or (c) prior to a Security Interest Termination Event, an event of default occurs under the 2032 Private Placement Notes. The 2024 Credit Facility is initially secured by a pledge of equity interests in the Subsidiary Guarantors. However, upon the achievement of certain security interest termination conditions, the pledges shall be released and the 2024 Credit Facility shall become unsecured (the “Security Interest Termination Event”). The Security Interest Termination Event occurs at the Borrower’s election, once the Borrower satisfies all of the following security interest termination conditions: (i) a fixed charge coverage ratio of no less than 1.50:1.00; (ii) an unsecured interest coverage ratio of not less than 2.00:1.00; (iii) a consolidated capitalization rate leverage ratio of not greater than 60%; and (iv) a secured debt ratio of no greater than 40%. Following the occurrence of the Security Interest Termination Event, certain terms and conditions of the 2024 Credit Facility are modified, including, but not limited to: (i) in certain circumstances, a reduction in the applicable rate under the 2024 Credit Facility, (ii) the modification or addition of certain financial covenants, (iii) the addition of a floor of at least $25 million for any cross-defaulted recourse debt of us, Borrower or any Subsidiary Guarantor, and (iv) in certain circumstances, a reduction in the annual unused fee for the 2024 Credit Facility. The outstanding 2032 Private Placement Notes previously issued by us remain pari passu with the 2024 Credit Facility. The 2024 Credit Facility contains certain customary representations and warranties, affirmative, negative and financial covenants, borrowing conditions, and events of default. In particular, the financial covenants imposed on us include: a maximum leverage ratio, a minimum fixed charge coverage ratio, a minimum tangible net worth, certain limits on both secured debt and secured recourse debt, certain payout ratios of dividends paid to adjusted funds from operations, limits on unhedged variable rate debt, and minimum liquidity. If an event of default occurs and continues, the Borrower is subject to certain actions by the administrative agent, including, without limitation, the acceleration of repayment of all amounts outstanding under the 2024 Credit Facility. 2027 NBC Loan On March 7, 2024, we, through five of our wholly-owned Canadian subsidiaries (the “2027 NBC Loan Borrowers”), entered into the 2027 NBC Loan with National Bank of Canada (“NBC”) as administrative agent, National Bank Financial as lead arranger and sole bookrunner, and certain other lenders party thereto. The 2027 NBC Loan has aggregate borrowings of $75 million CAD and is secured by the five properties owned by the 2027 NBC Loan Borrowers (the “Secured NBC Properties”). Previously, four of the Secured NBC Properties were included in the borrowing base of the 2024 Credit Facility, and the other property was previously unencumbered. The net proceeds from the 2027 NBC Loan were used to pay down the 2024 Credit Facility by approximately $55.1 million USD, and accordingly, the respective four properties were released as collateral from the 2024 Credit Facility. The 2027 NBC Loan has a maturity date of March 7, 2027, which may be extended for additional one-year periods in the sole discretion of the lenders. The 2027 NBC Loan carries a variable interest rate based on either the Canadian Overnight Repo Rate Average (“CORRA”) or the Canadian Prime Rate. Subsequent to the closing of the loan, we entered into an interest rate swap agreement based on CORRA with NBC whereby, inclusive of the swap we fixed the interest rate on the NBC loan at 6.42% for the initial three-year term of the loan. The 2027 NBC Loan requires monthly amortizing principal and interest payments, which are based on a 25-year amortization schedule. The 2027 NBC Loan may be prepaid, in whole or in part, at any time upon prior written notice to the lenders, subject to interest rate swap breakage costs. SmartStop and the 2027 NBC Loan Borrowers provided an indemnity in favor of NBC and the lenders for certain environmental matters. SmartStop serves as a non-recourse guarantor, and each borrower provided a limited recourse guaranty up to the amount of the collateral pledged by it, under the 2027 NBC Loan.

Principles of Consolidation	Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation.	Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”), the operating partnership of SST VI, and its wholly-owned subsidiaries, were consolidated by us from March 10, 2021 (the date of our initial investment in SST VI OP) until May 1, 2021. The portion not wholly-owned by us was presented as noncontrolling interests, and all intercompany accounts and transactions were eliminated when they were consolidated by us.
Consolidation Considerations	Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. Our Operating Partnership is deemed to be a VIE and is consolidated by us as we are currently the primary beneficiary. Our sole significant asset is our investment in our Operating Partnership; as a result, substantially all of our assets and liabilities represent those assets and liabilities of our Operating Partnership and its wholly-owned subsidiaries. Pacific Oak Holding Group, LLC, the parent company of Pacific Oak Capital Markets, LLC, the dealer manager for the public offering of SST VI, is a 17.5% non-voting As of September 30, 2024 and December 31, 2023, we were not a party to any other material contracts or interests that would be deemed variable interests in VIEs other than our joint ventures with SmartCentres, our Nantucket Joint Venture (as defined below), and our equity investments in the Managed REIT’s, which are all accounted for under the equity method of accounting (see Note 4 – Investments in Unconsolidated Real Estate Ventures and Note 10 – Related Party Transactions for additional information), and our joint venture programs through which we offer our tenant insurance, tenant protection plans or similar programs (the “Tenant Protection Programs”) with SST VI, SSGT III, and SSGT II (through June 1, 2022) which are consolidated.

Our sole significant asset is our investment in our Operating Partnership; as a result, substantially all of our assets and liabilities represent those assets and liabilities of our Operating Partnership and its wholly-owned subsidiaries. From March 10, 2021 until May 1, 2021, we were deemed to be the primary beneficiary of SST VI OP, and their operations were therefore consolidated by us. Subsequent to May 1, 2021, we are no longer the primary beneficiary, and their operations are no longer consolidated by us. On March 1, 2022, Pacific Oak Holding Group, LLC, the parent company of Pacific Oak Capital Markets, LLC, the dealer manager for the public offering of SST VI, became a 10% non-voting As of December 31, 2023, we were not a party to any other material contracts or interests that would be deemed variable interests in VIEs other than our joint ventures with SmartCentres and our equity investments in the Managed REIT’s, which are all accounted for under the equity method of accounting (see Note 4 – Investments in Unconsolidated Real Estate Ventures and Note 10 - Related Party Transactions for additional information), and our joint venture programs through which we offer our tenant insurance, tenant protection plans or similar programs (the “Tenant Protection Programs”) with SST VI, SSGT III, and SSGT II (through June 1, 2022) which are consolidated.
Equity Investments	Equity Investments Under the equity method, our investments are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and impairments, as applicable. Equity in earnings will generally be recognized based on our ownership interest in the earnings of each of the unconsolidated investments and recorded within our consolidated statements of operations.	Equity Investments Under the equity method, our investments are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and impairments, as applicable. Equity in earnings will generally be recognized based on our ownership interest in the earnings of each of the unconsolidated investments and recorded within our consolidated statements of operations. Our share of earnings and losses from our equity method investments in the JV Properties (as defined in Note 4 - Investments in Unconsolidated Real Estate Ventures) was previously included in Other, net within our consolidated statements of operations, but has been reclassified to Equity in earnings (losses) from investments in JV Properties within the current consolidated statements of operations included herein.
Investments in and Advances to Managed REITs	Investments in and Advances to Managed REITs As of September 30, 2024 and December 31, 2023, we had both equity and debt investments in the Managed REITs; such amounts are included in Investments in and advances to Managed REITs within our consolidated balance sheets. We account for the equity investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. We record the interest and related financing fees on our debt investments on the accrual basis and such income was previously included in Other, net, within our consolidated statements of operations. Such income has been reclassified to Interest income within the consolidated statements of operations included herein. While we do make loans periodically, we do not consider that to be part of our primary operating activity, and therefore do not report income from loans as operating income. See Note 10 – Related Party Transactions for additional information.

We account for the equity investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the respective Managed REIT’s earnings and reduced by distributions. Our share of earnings and losses from our equity method investments in the Managed REITs was previously included in Other, net within our consolidated statements of operations, but has been reclassified to Equity in earnings (losses) from investments in Managed REITs within our current consolidated statements of operations included herein. We record the interest on our debt investments on the accrual basis and such income is included in Other, net, within Other income (expense) of our consolidated statements of operations. While we do make loans periodically, we do not consider that to be part of our ordinary operating activity, and therefore do not report income from loans as operating income. See Note 10 – Related Party Transactions for additional information.
Noncontrolling Interests in Consolidated Entities	Noncontrolling Interests in Consolidated Entities We account for the noncontrolling interests in our Operating Partnership and the noncontrolling interests in SST VI Advisor and our Tenant Protection Programs joint ventures with SST VI, SSGT III, and SSGT II (prior to the SSGT II Merger on June 1, 2022) in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interests are reflected as noncontrolling interests in the accompanying consolidated balance sheets. We also consolidate our interests in the SSGT III and SST VI Tenant Protection Programs and present the minority interests as noncontrolling interests in the accompanying consolidated balance sheets. The noncontrolling interests shall be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interests balance.

Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management will adjust such estimates when facts and circumstances dictate. Actual results could materially differ from those estimates. The most significant estimates made include that of real estate acquisition valuation and the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed at relative fair value, the evaluation of potential impairment of indefinite and long-lived assets and goodwill, and the estimated useful lives of real estate assets and intangibles.

Cash and Cash Equivalents	Cash and Cash Equivalents We consider all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. We may maintain cash and cash equivalents in financial institutions in excess of insured limits. In an effort to mitigate this risk, we only invest in or through major financial institutions.

Real Estate Purchase Price Allocation and Treatment of Acquisition Costs	Real Estate Purchase Price Allocation and Treatment of Acquisition Costs We account for asset acquisitions in accordance with GAAP which requires that we allocate the purchase price of a property to the tangible and intangible assets acquired and the liabilities assumed based on their relative fair values as of the date of acquisition. This guidance requires us to make significant estimates and assumptions, including fair value estimates, which requires the use of significant unobservable inputs as of the acquisition date. We engage independent third-party valuation specialists to assist in the determination of significant estimates and market-based assumptions used in the valuation models. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month in-place, in-place Allocation of purchase price to acquisitions of portfolios of facilities are allocated to the individual facilities based upon an income approach or a cash flow analysis using appropriate risk adjusted capitalization rates which take into account the relative size, age, and location of the individual facility along with current and projected occupancy and rental rate levels or appraised values, if available. Acquisitions that do not meet the definition of a business, as defined under current GAAP, are accounted for as asset acquisitions. During the nine months ended September 30, 2024 and 2023, our property acquisitions did not meet the definition of a business. To date, our acquisitions have generally not met the definition of a business because substantially all of the fair value was concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) and because the acquisitions did not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. As a result, once an acquisition is deemed probable, acquisition related transaction costs are capitalized rather than expensed. During the three months ended September 30, 2024 and 2023, we expensed approximately $38,000 and $76,000, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods. During the nine months ended September 30, 2024 and 2023, we expensed approximately $121,000 and $118,000, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods.

During the years ended December 31, 2023, 2022, and 2021, our property acquisitions, including the SST IV Merger and the SSGT II Merger, did not meet the definition of a business because substantially all of the fair value was concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) and because the acquisitions did not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. As a result, once an acquisition is deemed probable, acquisition related transaction costs are capitalized rather than expensed. During the years ended December 31, 2023, 2022, and 2021 we expensed approximately $0.2 million, $0.9 million, and $0.9 million, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods.
Evaluation of Possible Impairment of Real Property Assets	Evaluation of Possible Impairment of Real Property Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our real property assets may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the real property assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the real property assets to the fair value and recognize an impairment loss. For the nine months ended September 30, 2023, no real property asset impairment losses were recognized. For the nine months ended September 30, 2024, we recorded a casualty loss in connection with damage to one of our wholly-owned properties caused by Hurricane Helene. Please see Note 3 – Real Estate for additional detail. Casualty Insurance Recoveries In the event of a wind storm, flood, fire or other such event causing property damage, we estimate the carrying value of the damaged property and record a corresponding casualty loss. If we determine that an insurance recovery is probable, we record such estimated recovery as a receivable up to the amount of the casualty loss. Any amount of insurance recovery for such loss in excess of the amount of the casualty loss recorded is considered a gain contingency and is recognized when the claim is fully settled.

Goodwill Valuation	Goodwill Valuation We initially recorded goodwill as a result of the Self Administration Transaction (as defined in Note 10 – Related Party Transactions), which occurred in 2019. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable, and is not amortized. We perform an annual qualitative impairment assessment as of December 31 for goodwill; between annual tests we evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. If circumstances indicate the carrying amount may not be fully recoverable, we perform a quantitative analysis to compare the fair value of each reporting unit to its respective carrying amount. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized.

Trademarks	Trademarks In connection with the Self Administration Transaction, we recorded the fair value associated with the two primary trademarks acquired therein. Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible fair value of our ownership of the brand name. As of September 30, 2024 and December 31, 2023, $15.7 million was recorded related to the SmartStop ® ® ® We qualitatively evaluate whether any triggering events or changes in circumstances have occurred in addition to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuation methods is adversely impacted, the impact could result in a material impairment charge in the future.

Revenue Recognition	Revenue Recognition Self Storage Operations Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. In accordance with ASC 842, we review the collectability of lease payments on an ongoing basis. We consider collectability indicators when analyzing accounts receivable and historical bad debt levels, including current economic trends, all of which assist in evaluating the probability of outstanding and future rental income collections. Additionally, we earn ancillary revenue from fees we receive related to providing tenant insurance or tenant protection plans to customers at our properties through our Tenant Protection Programs, and to a lesser extent, through the sale of various moving and packing supplies such as locks and boxes. We recognize such revenue in the Ancillary operating revenue line within our consolidated statements of operations as the services are performed and as the goods or services are delivered. Managed REIT Platform We earn property management and asset management revenue, pursuant to the respective property management and advisory agreement contracts, in connection with providing services to the Managed REITs. We have determined under ASC 606 – Revenue from Contracts with Customers (“ASC 606”), that the performance obligation for the property management services and asset management services are satisfied as the services are rendered. While we are compensated for our services on a monthly basis, these services represent a series of distinct daily services in accordance with ASC 606. Such revenue is recorded in the Managed REIT Platform revenue line within our consolidated statements of operations. The Managed REITs’ advisory agreements also provide for reimbursement to us of our direct and indirect costs of providing administrative and management services to the Managed REITs. These reimbursements include costs incurred in relation to organization and offering services provided to the Managed REITs and the reimbursement of salaries, bonuses, and other expenses related to benefits paid to our employees while performing services for the Managed REITs. The Managed REITs’ property management agreements also provide reimbursement to us for the property manager’s costs of managing the properties. Reimbursable costs include wages and salaries and other expenses that arise in operating, managing and maintaining the Managed REITs’ properties. Under ASC 606, direct reimbursement of such costs does not represent a separate performance obligation from our obligation to perform property management and asset management services. The reimbursement income is considered variable consideration, and is recognized as the costs are incurred, subject to limitations on the Managed REIT Platform’s ability to incur offering costs or limitations imposed by the advisory agreements. We have elected to separately record such revenue in the Reimbursable costs from Managed REITs line within our consolidated statements of operations. Additionally, we earn revenue in connection with our Tenant Protection Programs joint ventures with our Managed REITs. We also earn development and construction management revenue from services we provide in connection with the project design, coordination and oversight of development and certain capital improvement projects undertaken by the Managed REITs. We recognize such revenue in the Managed REIT Platform revenue line within our consolidated statements of operations as the services are performed or delivered. See Note 10 – Related Party Transactions, for additional information regarding revenue generated from our Managed REIT Platform. Sponsor Funding Agreement On November 1, 2023, SmartStop REIT Advisors, LLC, a subsidiary of our Operating Partnership, entered into a sponsor funding agreement (the “Sponsor Funding Agreement”) with SST VI and Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”) in connection with certain changes to the public offering of SST VI (see Note 10 – Related Party Transactions for additional information). Pursuant to the Sponsor Funding Agreement, SmartStop, through a wholly-owned subsidiary, is required to fund the payment of the front-end sales load for the sale of SST VI’s class Y and class Z shares sold in its offering. In exchange, SmartStop receives a number of series C convertible units (“Series C Units”) in SST VI OP calculated as the dollar amount of such funding divided by the then-current offering price, which was $9.30 through August 6, 2024 for such class Y and Z shares. The Series C Units shall automatically convert into class A units of SST VI OP on a one-to-one basis upon SST VI’s disclosure of an estimated net asset value per share equal to at least $10.00 per share for each class of SST VI shares of common stock, including the class Y shares and class Z shares, calculated net of the Series C Units to be converted. On August 7, 2024, SST VI declared an estimated net asset value per share of $10.00. Since the Series C Units that could be converted would result in the net asset value falling below $10.00 per share, none of the Series C Units we own were converted into class A units of SST VI OP, and our future purchases will be determined based on the current estimated net asset value at such time. Subsequent to SST VI declaring an estimated net asset value of $10.00 per share, the number of Series C Units SmartStop receives in exchange for funding the front-end sales load of the sale of SST VI’s class Y and class Z shares is calculated as the dollar amount of such sponsor funding divided by the current offering price of $10.00 per share for such class Y and Z shares. In accordance with ASC 606, the amount by which our funding exceeds the fair value of the Series C Units received is accounted for as a payment to a customer and is therefore recorded as a reduction to the transaction price for the services we provide to such customer. Each payment is initially included in the Other assets line-item in our consolidated balance sheet and subsequently recorded as a reduction of Managed REIT Platform revenues ratably over the remaining estimated life of our management contracts with SST VI. Below is a summary of the portion of sponsorship funding payments which exceeds the fair value of the Series C Units received, and is recorded pursuant to ASC 606 as described above (in thousands): Balance as of December 31, 2022 $ —  Amounts incurred 3,527 Recorded sponsor funding reduction (34 ) Balance as of December 31, 2023 $ 3,493 Amounts incurred $ 932 Recorded sponsor funding reduction (598 ) Balance as of September 30, 2024 $ 3,827	Revenue Recognition Self Storage Operations Management believes that all of our leases are operating leases.

Redeemable Common Stock	Redeemable Common Stock We adopted a share redemption program (“SRP”) that enables stockholders to sell their shares to us in limited circumstances. We have evaluated the terms of our SRP, and we classify amounts that are redeemable under the SRP as redeemable common stock in the accompanying consolidated balance sheets. The maximum amount of redeemable shares under our SRP is limited to the net proceeds from the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation of us to repurchase shares be classified as liabilities and reported at settlement value. When we determine we have a mandatory obligation to repurchase shares under the SRP, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. See Note 12 – Commitments and Contingencies for additional information on our SRP.	Redeemable Common Stock We adopted a share redemption program (“SRP”) that enables stockholders to sell their shares to us in limited circumstances. We have evaluated the terms of our SRP, and we classify amounts that are redeemable under the SRP as redeemable common stock in the accompanying consolidated balance sheets. The maximum amount of redeemable shares under our SRP is limited to the net proceeds from the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation of us to repurchase shares be classified as liabilities and reported at settlement value. When we determine we have a mandatory obligation to repurchase shares under the SRP, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. See Note 12 – Commitments and Contingencies for additional information on our SRP.
Accounting for Equity Awards	Accounting for Equity Awards We issue equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”), both of which may be issued subject to either time based vesting criteria or performance based vesting criteria restrictions. For time based awards granted which contain a graded vesting schedule, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For performance based awards, compensation cost is recognized over the requisite service period if and when we determine the performance condition is probable of being achieved. We record the cost of such equity based awards based on the grant date fair value, and have elected to record forfeitures as they occur.

Employee Benefit Plan	Employee Benefit Plan The Company maintains its own retirement savings plan under Section 401(k) of the Internal Revenue Code, as amended (the “Code”), under which eligible employees can contribute up to 100% of their annual salary, subject to a statutory prescribed annual limit. The Company matches 100% on contributions up to the first 4% of an employee’s compensation.	Employee Benefit Plan The Company terminated its relationship with a professional employer organization and began maintaining its own retirement savings plan during the year ended December 31, 2021 under Section 401(k) of the Internal Revenue Code under which eligible employees can contribute up to 100% of their annual salary, subject to a statutory prescribed annual limit. For the year ended December 31, 2023 and 2022, the Company made matching contributions to such plan of approximately $0.5 million and $0.5 million, respectively, based on a company match of 100% on the first 4% of an employee’s compensation.
Fair Value Measurements	Fair Value Measurements Under GAAP, we are required to measure certain financial instruments at fair value on a recurring basis. In addition, we are required to measure other financial instruments and balances at fair value on a non-recurring • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; • Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and • Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety. The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we will utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment will be necessary to interpret Level 2 and 3 inputs in determining fair value of our financial and non-financial Financial and non-financial non-recurring along with the assets and liabilities described in Note 3 – Real Estate Facilities. The fair values of these assets and liabilities were determined as of the acquisition dates using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) market approach, which considers comparable sales activity. Additionally, certain such assets and liabilities are required to be fair valued periodically or valued pursuant to ongoing fair value requirements and impairment analyses and have been valued subsequently utilizing the same techniques noted above. In general, we consider multiple valuation techniques when measuring fair values. However, in certain circumstances, a single valuation technique may be appropriate. All of the fair values of the assets and liabilities as of the acquisition dates were derived using Level 3 inputs. The Series C Units (categorized within Level 3 of the fair value hierarchy) acquired in connection with the Sponsor Funding Agreement are measured at fair value at the time of acquisition, and are accounted for using the equity method of accounting as described in Note 10 – Related Party Transactions. The fair value of these units were determined upon purchase using a valuation model which considered the following key assumptions: the projected distribution rate of SST VI, implied share price volatility, risk free interest rate, current estimated net asset value, and the estimated effective life of the Series C Units. The carrying amounts of cash and cash equivalents, restricted cash, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates approximate fair value (categorized within Level 1 of the fair value hierarchy). The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of our fixed and variable rate debt was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities (categorized within Level 2 of the fair value hierarchy). The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. As of September 30, 2024 and December 31, 2023, we believe the fair value of our variable rate debt was reasonably estimated at their notional amounts as there have been minimal changes to the fixed spread portion of interest rates for similar loans observed in the market, and as the variable portion of our interest rates fluctuate with the associated market indices. The table below summarizes the carrying amounts and fair values of our fixed rate debt which are not carried at fair value as of September 30, 2024 and December 31, 2023 (in thousands): September 30, 2024 December 31, 2023 Fair Value Carrying Fair Value Carrying Fixed Rate Secured Debt $ 502,200 $ 519,471 $ 505,700 $ 523,019 During the nine months ended September 30, 2024 and 2023, we held interest rate cash flow hedges and foreign currency net investment hedges to hedge our interest rate and foreign currency exposure (See Notes 5 – Debt and 7 – Derivative Instruments). The fair value analyses of these instruments reflect the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities, as applicable. The fair value of interest rate swap and cap agreements are determined using widely accepted valuation techniques, including discounted cash flow analyses on the expected cash flows of the instruments. Our fair values of our net investment hedges are based primarily on the change in the spot rate at the end of the period as compared with the strike price at inception. To comply with GAAP, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of derivative contracts for the effect of non-performance Although we had determined that the majority of the inputs used to value our derivatives were within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilized Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and our counterparties. However, through September 30, 2024, we had assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of our derivatives. As a result, we determined that our 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, 2024 and December 31, 2023, aggregated by the level in the fair value hierarchy within which those measurements fall (in thousands): Fair Value Measurements at Description Quoted Significant Significant Other assets - interest rate derivatives $ —  $ 202 $ —  Accounts payable and accrued liabilities - interest rate derivatives $ —  $ 5,656 $ —  Accounts payable and accrued liabilities - foreign currency hedges $ —  $ 1,326 $ —  Fair Value Measurements at Description Quoted Significant Significant Other assets - interest rate derivatives $ —  $ 3,485 $ —  Accounts payable and accrued liabilities - foreign currency hedges $ —  $ 985 $ —	Fair Value Measurements Under GAAP, we are required to measure certain financial instruments at fair value on a recurring basis.

Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We record all derivatives on our balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. For derivatives designated as net investment hedges, the effective portion of changes in the fair value of the derivatives are reported in accumulated other comprehensive income (loss). The ineffective portion of the change in fair value of the derivatives is recognized in Other, net, within our consolidated statements of operations. Amounts are reclassified out of other comprehensive (loss) income (“OCI”) into earnings (loss) when the hedged net investment is either sold or substantially liquidated.

Income Taxes	Income Taxes We made an election to be taxed as a Real Estate Investment Trust (“REIT”), under Sections 856 through 860 of the Code, commencing with our taxable year ended December 31, 2014. To qualify as a REIT, we must continue to meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the REIT’s taxable income to stockholders (which is computed without regard to the dividends paid deduction or net capital gains and which does not equal net income as calculated in accordance with GAAP). For income tax purposes, distributions to common stockholders are characterized as ordinary dividends, capital gain dividends, or as nontaxable distributions. To the extent that we make a distribution in excess of our current or accumulated earnings and profits, the distribution will be a non-taxable As a REIT, we generally will not be subject to U.S. federal income tax on taxable income that we distribute to our stockholders. If we fail to qualify as a REIT in any taxable year, we will then be subject to U.S. federal income taxes on our taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for U.S. federal income tax purposes for four years following the year during which qualification is lost unless the IRS grants us relief under certain statutory provisions. Such an event could materially adversely affect our net income and net cash available for distribution to stockholders. However, we believe that we are organized and operate in such a manner as to qualify for treatment as a REIT and intend to operate in the foreseeable future in such a manner that we will remain qualified as a REIT for U.S. federal income tax purposes. Even if we continue to qualify for taxation as a REIT, we may be subject to certain state, local, and foreign taxes on our income and property, and federal income and excise taxes on our undistributed income. We filed an election to treat our primary taxable REIT subsidiary (“TRS”) as a taxable REIT subsidiary effective January 1, 2014. In general, our TRS performs additional services for our customers and provides the advisory and property management services to the Managed REITs and otherwise generally engages in non-real We account for deferred income taxes using the asset and liability method and recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Any increase or decrease in the deferred tax liability that results from a change in circumstances, and that causes a change in our judgment about expected future tax consequences of events, is included in the tax provision when such changes occur. Deferred income taxes also reflect the impact of operating loss and tax credit carryforwards. A valuation allowance is provided if we believe it is more likely than not that all or some portion of the deferred tax asset will not be realized. Any increase or decrease in the valuation allowance that results from a change in circumstances, and that causes a change in our judgment about the realizability of the related deferred tax asset, is included in the tax provision when such changes occur. Uncertain tax positions may arise where tax laws may allow for alternative interpretations or where the timing of recognition of income is subject to judgment. Under ASC Topic 740, tax positions are evaluated for recognition using a more–likely–than–not threshold, and those tax positions requiring recognition are measured at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties relating to uncertain tax positions will be recognized in income tax expense when incurred. As of September 30, 2024 and December 31, 2023, the Company had no uncertain tax positions. Income taxes payable are classified within accounts payable and accrued liabilities in the consolidated balance sheets. The tax years 2020-2023 remain open to examination by the major taxing jurisdictions to which we are subject.

Concentration	Concentration No single self storage customer represents a significant concentration of our revenues. For the nine months ended September 30, 2024, approximately 22%, 20%, and 10% of our rental income was concentrated in Florida, California, and the Greater Toronto Area of Canada, respectively. Our properties within the aforementioned geographic areas are dispersed therein, operating in multiple different regions and sub-markets.

Convertible Preferred Stock	Convertible Preferred Stock We classify our Series A Convertible Preferred Stock (as defined in Note 6 – Preferred Equity) on our consolidated balance sheets using the guidance in ASC 480-10-S99. Our Series A Convertible Preferred Stock can be redeemed by us on or after the fifth anniversary of its issuance (October 29, 2024), or if certain events occur, such as the listing of our common stock on a national securities exchange, a change in control, or if a redemption would be required to maintain our REIT status. Additionally, if we do not maintain our REIT status the holder can require redemption. As the shares are contingently redeemable, and under certain circumstances not solely within our control, we have classified our Series A Convertible Preferred Stock as temporary equity. We have analyzed whether the conversion features in our Series A Convertible Preferred Stock should be bifurcated under the guidance in ASC 815-10 and have determined that bifurcation is not necessary.

Recently Issued Accounting Guidance	Recently Issued Accounting Guidance In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280).” The guidance in ASU 2023-07 was issued to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendment becomes effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Other than the required incremental disclosures, we do not expect it to have a material impact on our consolidated financial statements and related disclosures. We expect to adopt this ASU for the annual report on Form 10-K for the year ending December 31, 2024. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740).” The guidance in ASU 2023-09 was issued to provide investors with information to better assess how an entity’s operations and related tax risks, tax planning and operational opportunities affect its tax rate and prospects for future cash flows. The amendment becomes effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact upon adoption of the new standard on our consolidated financial statements and related disclosures. In March 2024, the FASB issued ASU 2024-01, “Compensation–Stock Compensation (Topic 718).” ASU 2024-01 adds illustrative guidance in ASC 718 and was issued to reduce complexity in determining whether a profits interest award is subject to the guidance in Topic 718, and to reduce existing diversity in practice. ASU 2024-01 clarifies how to determine whether profits interest and similar awards should be accounted for as a share-based payment arrangement under ASC 718, or as a cash bonus or profit-sharing arrangement under ASC 710 or other guidance, and applies to all reporting entities that account for profits interest awards as compensation to employees or non-employees. The amendment becomes effective for fiscal years beginning after December 15, 2024, including interim periods within those annual periods, with early adoption permitted. The amendments should be applied either retrospectively to all prior periods presented in the financial statements, or prospectively to profits interest and similar awards granted or modified on or after the adoption date. We are currently assessing the impact upon adoption of the new standard on our consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses (Topic 220).” The guidance in ASU 2024-03 was issued to provide investors with more disaggregated information about an entity’s expenses. The amendment becomes effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. We are currently evaluating the impact upon adoption of the new standard on our consolidated financial statements and related disclosures.

Summary of Fixed Rate Notes Payable	The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of our fixed and variable rate debt was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities (categorized within Level 2 of the fair value hierarchy). The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. As of September 30, 2024 and December 31, 2023, we believe the fair value of our variable rate debt was reasonably estimated at their notional amounts as there have been minimal changes to the fixed spread portion of interest rates for similar loans observed in the market, and as the variable portion of our interest rates fluctuate with the associated market indices. The table below summarizes the carrying amounts and fair values of our fixed rate debt which are not carried at fair value as of September 30, 2024 and December 31, 2023 (in thousands): September 30, 2024 December 31, 2023 Fair Value Carrying Fair Value Carrying Fixed Rate Secured Debt $ 502,200 $ 519,471 $ 505,700 $ 523,019	The table below summarizes the carrying amounts and fair values of financial instruments that are not carried at fair value as of December 31, 2023 and 2022.

One of our 14 wholly-owned properties in this market was severely flooded. As a result of the storm event, flooding and related damage, we recorded a net casualty loss related to this property of approximately $4.6 million during the three and nine months ended September 30, 2024, to write-off the carrying value. We expect to rebuild and therefore we believe it is probable that we will receive insurance proceeds to offset the casualty loss and have recorded a receivable related to our pending insurance claims. Consequently the casualty loss was completely offset in our consolidated statements of operations by such recovery. Any amount of insurance recovery related to the property damage in excess of the casualty loss incurred is considered a gain contingency, and will be recognized upon final settlement of the claims.

[1]Hurricane Helene caused record flooding in late September 2024 in Asheville, North Carolina. One of our 14 wholly-owned properties in this market was severely flooded. As a result of the storm event, flooding and related damage, we recorded a net casualty loss related to this property of approximately $4.6 million during the three and nine months ended September 30, 2024, to write-off the carrying value. We expect to rebuild and therefore we believe it is probable that we will receive insurance proceeds to offset the casualty loss and have recorded a receivable related to our pending insurance claims. Consequently the casualty loss was completely offset in our consolidated statements of operations by such recovery. Any amount of insurance recovery related to the property damage in excess of the casualty loss incurred is considered a gain contingency, and will be recognized upon final settlement of the claims.

[1]On March 17, 2021, in connection with the SST IV Merger, we assumed a $40.5 million fixed rate CMBS financing with KeyBank as the initial lender pursuant to a mortgage loan (the “SST IV CMBS Loan”). This fixed rate loan encumbers seven properties owned by us (Jensen Beach, Texas City, Riverside, Las Vegas IV, Puyallup, Las Vegas V, and Plant City). The separate assets of these encumbered properties are not available to pay our other debt. The loan has a maturity date of February 1, 2030. Monthly payments due under the loan agreement (the “SST IV CMBS Loan Agreement”) are interest only, with the full principal amount becoming due and payable on the maturity date.[2]On April 15, 2021, we purchased the Oakville III Property. We partially financed the Oakville III Property acquisition with a loan from Bank of Montreal (the “Oakville III BMO Loan”), which was secured by a first lien on the Oakville III Property. The loan is denominated in Canadian dollars and the proceeds from the loan were approximately CAD $16.3 million. The interest only loan was prepayable at any time without penalty. On March 24, 2023, we fully paid off this loan, including all outstanding accrued interest.[3]The amounts shown above are in USD based on the foreign exchange rate in effect as of the date presented.[4]This fixed rate loan encumbers 29 properties (Whittier, La Verne, Santa Ana, Upland, La Habra, Monterey Park, Huntington Beach, Chico, Lancaster I, Riverside, Fairfield, Lompoc, Santa Rosa, Federal Heights, Aurora, Littleton, Bloomingdale, Crestwood, Forestville, Warren I, Sterling Heights, Troy, Warren II, Beverly, Everett, Foley, Tampa, Boynton Beach, and Lancaster II) with monthly interest only payments until September 2021, at which time both interest and principal payments became due monthly. The separate assets of these encumbered properties are not available to pay our other debts.[5]This fixed rate loan encumbers 29 properties (Whittier, La Verne, Santa Ana, Upland, La Habra, Monterey Park, Huntington Beach, Chico, Lancaster I, Riverside, Fairfield, Lompoc, Santa Rosa, Federal Heights,Aurora, Littleton, Bloomingdale, Crestwood, Forestville, Warren I, Sterling Heights, Troy, Warren II, Beverly, Everett, Foley, Tampa, Boynton Beach, and Lancaster II) with monthly interest only payments until September 2021, at which time both interest and principal payments became due monthly. The separate assets of these encumbered properties are not available to pay our other debts.[6]This fixed rate loan encumbers five properties (Pompano Beach, Lake Worth, Jupiter, Royal Palm Beach, and Delray) with monthly interest only payments until June 2022, at which time both interest and principal payments became due monthly. The separate assets of these encumbered properties are not available to pay our other debts.[7]This fixed rate, interest only loan encumbers 10 properties (Myrtle Beach I, Myrtle Beach II, Port St. Lucie, Plantation, Sonoma, Las Vegas I, Las Vegas II, Las Vegas III, Ft Pierce, and Nantucket Island). The separate assets of these encumbered properties are not available to pay our other debts.[8]As of March 31, 2023, a Total Leverage Ratio Event (as defined below) had occurred, and the interest rate on such Note increased to 5.28% prospectively. For additional information regarding this loan, see 2032 Private Placement Notes below.[9]As of March 31, 2023, a Total Leverage Ratio Event (as defined below) had occurred, and the interest rate on such Note increased to 5.28% prospectively. For additional information regarding this loan, see below.[10]On November 16, 2023, we, through eight of our wholly-owned Canadian subsidiaries entered into a term loan (the “2028 Canadian Term Loan”) with affiliates of QuadReal Finance LP, receiving net proceeds of $110.0 million CAD on such date. The 2028 Canadian Term Loan is secured by eight Canadian properties, has a maturity date of December 1, 2028, and carries a fixed interest rate for the term of the loan of 6.41%. The first two years of the Canadian Term Loan are interest only, after which it requires monthly amortizing payments based on a 25-year amortization schedule.[11]This loan incurs interest at an all in rate of CORRA (as defined further below under the section entitled “2027 NBC Loan”), plus a CORRA adjustment of approximately 0.30%, plus a spread of 2.20%. Theeffective interest rate on this loan is 6.42% when factoring the effects of a CORRA Swap which we entered into with the National Bank of Canada for the initial term of the loan. The Dufferin, Oakville II, Burlington II, Iroquois Shore Rd, and Stoney Creek I properties are encumbered by this loan. See Note 7 – Derivative Instruments for additional information.

[1]Pursuant to the Sponsor Funding Agreement, SmartStop funds certain costs of SST VI's share sales, and in return receives Series C Units in SST VI's OP. The excess of the funding over the value of the Series C Units received is accounted for as a reduction of Managed REIT Platform revenues from SST VI over the remaining estimated term of the management contracts with SST VI.[2]On March 17, 2021, we acquired SST IV and no longer earn such fees. Additionally, the Tenant Protection Program revenue for SST IV is now included in ancillary operating revenue in our consolidated statements of operations.[3]On June 1, 2022, we acquired SSGT II and no longer earn such fees. Additionally, the Tenant Protection Program revenue for SSGT II is now included in ancillary operating revenue in our consolidated statements of operations.[4]Such revenue primarily includes other property management related fees, construction management fees, development fees, and other miscellaneous revenues.
