Development properties

Bradenton Land

On February 16, 2023, we, through an indirect, wholly-owned subsidiary of our Operating Partnership, acquired a parcel of land adjacent to our property in Bradenton, Florida (the “Bradenton Land”) from an unaffiliated third party. The purchase price for the Bradenton Land was approximately $1.4 million, plus closing costs and an acquisition fee to our advisor. We are in the process of expanding our current self storage property on the Bradenton Land. As of December 31, 2025, estimated development cost to complete the expansion are approximately $2.1 million, which we expect to fund with a combination of net proceeds from our Series E Preferred Offering and/or potential future debt financing.

Etobicoke Land

On March 27, 2023, we, through an indirect, wholly-owned subsidiary of our Operating Partnership, acquired a parcel of land to be developed into a self storage facility located in Etobicoke, in the city of Toronto, Ontario (the “Etobicoke Land”) from an unaffiliated third party. The purchase price for the Etobicoke Land was approximately CAD $2.2 million, plus closing costs and an acquisition fee to our advisor. As of December 31, 2025, our cost to complete development is approximately CAD $5.3 million, which we expect to fund with the Meridian financing, as described below.

On March 6, 2025, we through wholly-owned subsidiary of our Operating Partnership, entered into a credit agreement with Meridian Credit Union Limited ("Meridian") with a maximum borrowing capacity of CAD $16.0 million. As of December 31, 2025, we had drawn approximately CAD $10.4 million and have CAD $5.6 million available. Please see Note 5 - Debt of the Notes to the Consolidated Financial Statements contained elsewhere in this report for additional information.

In February 2026, we substantially completed development and commenced operations at the Etobicoke Property.

Investments in Unconsolidated Real Estate Ventures

We have entered into joint venture agreements with a subsidiary of SmartCentres, an unaffiliated third party, to acquire tracts of land and develop them into 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. Equity in earnings (loss) will generally be recognized based on our ownership interest in the earnings (loss) of each of the unconsolidated investments.

The following table summarizes our 50% ownership interests in unconsolidated real estate ventures as of December 31, 2025:

• The Series D Preferred Units rank senior to all common units in our operating partnership, as well as the Series E Preferred Stock, and therefore, any cash we have to pay distributions may be used to pay distributions to the Series D Preferred Investor first, which could have a negative impact on our ability to pay distributions to you.
• The Series E Preferred Stock rank senior to all classes or series of common stock in our company, and therefore, any cash we have to pay distributions may be used to pay distributions to the Series E Preferred Investors first, which could have a negative impact on our ability to pay distributions to you.
• The value of a share of our common stock may be diluted if we issue a stock distribution.
• As a result of our sponsor paying the front-end load pursuant to the Sponsor Funding Agreement and the ultimate conversion of the Series C Units to be issued to the sponsor into Class A Units, the holders of the Class W shares and Class Z shares would suffer more dilution than holders of the Class T shares and Class Y shares relative to shares that were or could have been sold previously through RIAs net of the front-end load resulting in a gross-up of shares.
• If we, through our Advisor, are unable to find suitable investments, then we may not be able to achieve our investment objectives or continue to pay distributions.
• We may suffer from delays in locating suitable investments, which could adversely affect our ability to make distributions and the value of stockholders’ investments.
• If any of our Sponsor, Advisor, or Property Manager lose or are unable to retain their executive officers, then our ability to implement our investment objectives could be delayed or hindered, which could adversely affect our ability to make distributions and the value of an investment in us.
• Our ability to operate profitably will depend upon the ability of our Advisor to efficiently manage our day-to-day operations and the ability of our Property Manager and affiliates of our Advisor to effectively manage our properties.
• We do not own or control the intellectual property rights to the “SmartStop® Self Storage” brand and other trademarks and intellectual property that we expect to use in connection with our properties; therefore, we could potentially lose revenues and incur significant costs if we cease to operate under this brand.
• We are an “emerging growth company” under the federal securities laws and will be subject to reduced public company reporting requirements.
• We may utilize a portion of the proceeds of our offerings to fund the development or purchase of income-producing and growth self storage properties (whether through loans, preferred equity investments, or otherwise), and we may invest in mortgage or other loans, but if these loans and investments are not fully repaid, the resulting losses could reduce the value of a stockholder’s investment.
• Government regulation of investment advice could have a negative impact on our ability to raise capital.
• Risks Related to Conflicts of Interest
• Our Advisor, Property Manager, and their officers and certain of our key personnel will face competing demands relating to their time, and this may cause our operating results to suffer.
• Our executive officers and one of our directors face conflicts of interest related to the positions they hold with affiliated entities, which could hinder our ability to successfully implement our investment objectives and to generate returns to stockholders.
• Our Advisor will face conflicts of interest relating to the purchase of properties, including conflicts with SmartStop, SSGT III and SST X, and such conflicts may not be resolved in our favor, which could adversely affect our investment opportunities.
• We may face a conflict of interest if we purchase properties from affiliates of our Advisor.
• We may face a conflict of interest if we sell properties to affiliates of our Advisor.
• Our Advisor and its affiliates will face conflicts of interest relating to the Series C Units and the incentive fee structure under our operating partnership agreement, which could result in actions that are not necessarily in the long-term best interests of our stockholders.
• Our Advisor will face conflicts of interest relating to joint ventures that we may form with affiliates of our Advisor, which conflicts could result in a disproportionate benefit to other joint venture partners at our expense.
• There is no separate counsel for us and our affiliates, which could result in conflicts of interest.
• Risks Related to Our Corporate Structure
• The limit on the number of shares a person may own may discourage a takeover that could otherwise result in a premium price to our stockholders.
• Our charter permits our board of directors to issue stock with terms that may subordinate the rights of common stockholders or discourage a third party from acquiring us in a manner that might result in a premium price to our stockholders.
• We will not be afforded the protections of Maryland law relating to control share acquisitions and business combinations.
• SSA may receive economic benefits from its status as a special limited partner without bearing any of the investment risk.
• A stockholders’ investment return may be reduced if we are required to register as an investment company under the Investment Company Act of 1940; if we become an unregistered investment company, we will not be able to continue our business.
• Stockholders are bound by the majority vote on matters on which our stockholders are entitled to vote and, therefore, a stockholder vote on a particular matter may be superseded by the vote of other stockholders.
• Our stockholders have limited control over changes in our policies and operations and may not be able to change such policies and operations, except as provided for in our charter and under applicable law.
• Our rights and the rights of our stockholders to recover claims against our officers, directors, and our Advisor are limited, which could reduce our stockholders’ and our recovery against them if they cause us to incur losses.
• Our board of directors may change any of our investment objectives without our stockholders’ consent, including our focus on income-producing and growth self storage properties.
• Our stockholders’ interests in us will be diluted as we issue additional shares.
• Payment of fees to our Advisor and its affiliates will reduce cash available for investment and distribution. There are a number of such fees that may have to be paid and certain fees may be added or the amounts increased without stockholder approval.
• We are uncertain of our sources of debt or equity for funding our future capital needs. If we cannot obtain funding on acceptable terms, our ability to make necessary capital improvements to our properties, pay other expenses, or expand our business may be impaired or delayed.
• Risks Related to the Self Storage Industry
• The growth portion of our property acquisition strategy involves a higher risk of loss than more conservative investment strategies.
• Because we are focused on the self storage industry, our rental revenues will be significantly influenced by demand for self storage space generally, and a decrease in such demand would likely have a greater adverse effect on our rental revenues than if we owned a more diversified real estate portfolio.
• We face significant competition in the self storage industry, which may increase the cost of acquisitions or developments or impede our ability to retain customers or re-let space when existing customers vacate.
• The acquisition of new properties may give rise to difficulties in predicting revenue potential.
• We may be unable to promptly re-let units within our facilities at satisfactory rental rates.
• We may not be successful in identifying and consummating suitable acquisitions, or integrating and operating acquired properties, which may adversely impact our growth and results of operations.
• We depend on our property manager’s on-site personnel to maximize customer satisfaction at each of our facilities, and any difficulties our property manager encounters in hiring, training, and retaining skilled field personnel may adversely affect our rental revenues.
• Legal claims related to moisture infiltration and mold could arise in one or more of our properties, which could adversely affect our revenues.
• Delays in development and lease-up of our properties would reduce our profitability.
• The risks associated with storage contents may increase our operating costs or expose us to potential liability that may not be covered by insurance, which may have adverse effects on our business, financial condition, and results of operations.
• Our operating results may be affected by regulatory changes that have an adverse impact on our specific facilities, which may adversely affect our business, financial condition, and results of operations.
• General Risks Related to Investments in Real Estate
• Our operating results will be affected by economic and regulatory changes that have an adverse impact on the real estate market in general, and we cannot assure stockholders that we will be profitable or that we will realize growth in the value of our real estate properties.
• We may suffer reduced or delayed revenues for, or have difficulty selling, properties with vacancies.
• Our operating results may be negatively affected by our construction and development activities, whether as a result of an increased cost of labor and materials, or increased costs and risks associated with potential development and construction delays, each of which could diminish the return on a stockholder’s investment.
• We may obtain only limited warranties when we purchase a property.
• If we enter into non-compete agreements with the sellers of the properties that we acquire, and the terms of those agreements expire, the sellers may compete with us within the general location of one of our properties, which could have an adverse effect on our operating results and returns to our stockholders.
• Costs of complying with governmental laws and regulations, including those relating to environmental matters, may adversely affect our income and the cash available for distribution.
• Costs of complying with governmental laws and regulations, including those relating to regulations accommodating disabilities, may affect cash available for distribution.
• Our inability to sell a property when we desire to do so could adversely impact our ability to pay cash distributions to our stockholders.
• We may not be able to sell our properties at a price equal to, or greater than, the price for which we purchased such properties, which may lead to a decrease in the value of our assets.
• We may acquire or finance properties with lock-out provisions, which may prohibit us from selling a property, or may require us to maintain specified debt levels for a period of years on some properties.
• If we sell properties by providing financing to purchasers, defaults by the purchasers would adversely affect our cash flows.
• Rising expenses could reduce cash flow and funds available for future acquisitions.
• If we suffer losses that are not covered by insurance or that are in excess of insurance coverage, we could lose invested capital and anticipated profits.
• Delays in the acquisition, development, and construction of properties may have adverse effects on our results of operations and returns to our stockholders.
• Increases in interest rates may adversely affect the demand for our shares.
• Property taxes may increase, which will adversely affect our net operating income and cash available for distributions.
• We will be subject to risks associated with joint venture partners in joint venture arrangements that otherwise may not be present in other real estate investments.
• Investments in properties or other real estate investments outside the United States subject us to foreign currency risks, which may adversely affect distributions and our REIT status.
• Changes in the Canadian Dollar/USD exchange rate could have a material adverse effect on our operating results and value of the investment of our stockholders.
• We are subject to additional risks as a result of any joint venture interest or properties we acquire in Canada.
• Changes in U.S. trade policy, including significant tariffs or other restrictions imposed on imports by the U.S. and related countermeasures taken by impacted foreign countries, could have a material adverse effect on our business.
