See Note 3, Real Estate Facilities—Merger with Strategic Storage Growth Trust, Inc., of the Notes to the Consolidated Financial Statements, for more information.

Equity

The Company was formed on January 8, 2013, under the Maryland General Corporation Law.  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 48.4 million shares of Class A common stock (“Class A Shares”) and approximately 7.3 million shares of Class T common stock (“Class T Shares”) for approximately $493 million and $73 million respectively.

In November 2016, we filed with the SEC a Registration Statement on Form S-3, which registered up to an additional $100.9 million in shares under our distribution reinvestment plan (our “DRP Offering”). The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. As(as of December 31, 2020, we had sold approximately 5.3 million Class A Shares and approximately 0.8 million Class T Shares for approximately $55.5 million and $8.5 million, respectively, in our DRP Offering.

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 shares (the aggregate shares to be purchased, the “Preferred Shares”) of our Series A Convertible Preferred Stock (the “Series A Convertible Preferred Stock”), in one or more closings (each, a “Closing,” and collectively, the “Closings”)2023). 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.

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, 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.  See Note 8, Preferred Equity, of the Notes to the Consolidated Financial Statements, for more information.

On April 20, 2020, our board of directors, upon recommendation of our NominatingOur primary business model is focused on owning and Corporate Governance Committee, approved an estimated value per share of our common stock of $10.40 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 December 31, 2019.

As a result of the calculation of our estimated value per share, beginningoperating high quality self storage properties in May 2020, shares sold pursuant to our DRP Offering are being sold at the estimated value per share of $10.40 for both Class A Shares and Class T Shares.

COVID-19

The global economy has been adversely impacted by the COVID-19 pandemic, includinghigh growth markets in the United States and Canada. We finance our portfolio through a diverse capital strategy which includes cash generated from operations, borrowings under our syndicated revolving line of credit, secured debt financing, equity offerings and joint ventures. Our business model is designed to maximize cash flow available for distribution to our stockholders and to achieve sustainable long-term growth in cash flow in order to maximize long-term stockholder value at acceptable levels of risk. We execute our organic growth strategy by pursuing revenue-optimizing and expense-minimizing opportunities in the markets in which we operate. The COVID-19 pandemic and the resulting effects, including shutdowns or weakness in national, regional and local economies have affected our business, primarily starting in late March of 2020. During the second quarter of 2020, many of the factors underlying the demand for self storage were negatively impacted, but improved during the third and fourth quarters. Future governmental orders or broad economic weakness could adversely impact our business, financial condition, liquidity and results of operations however, the extent and duration to which our operations will be impacted is highly uncertain and cannot be predicted.

Strategic Storage Trust VI

We, through our subsidiary, SRA, now serve as sponsor for SST VI, a private REIT focused on acquiring income and growth self storage properties.  On March 10, 2021, SmartStop OP made an investment of $5.0 million in Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”), the operating partnership of SST VI, in exchange for common units of limited partnership interest in SST VI OP. On March 11, 2021, SST VI OP, through a wholly-owned subsidiary, acquired its first self storage facility in Phoenix, Arizona for approximately $16 million. SST VI commenced a private offering in the first quarter of 2021. Given our current level of ownership, we initially expect to consolidate SST VI in our financial statements until the equity raised in SST VI’s private offering increases the level of outside ownership.

In connection with SST VI’s acquisition of the Phoenix property, we provided a $3.5 million mezzanine loan to a wholly-owned subsidiary of SST VI’s operating partnership with an initial interest rate of 8.5% and term of six months; as well as a 180 day extension option which, if exercised, would increase the interest rate to 9.25%. In addition to the aforementioned mezzanine loan, SST VI financed the acquisition, in part, by obtaining a third party mortgage loan on the property of approximately $9 million, which had an initial interest rate of 3.5%, and a three year term, with two one year extension options.

Industry and Competition

“Self storage” refers to properties that offer do-it-yourself, month-to-month storage unit rental for personal or business use. Self storage offers a cost-effective and flexible storage alternative. Customers rent fully-enclosed spaces that can vary in size according to their specific needs. Customers typically have access to their storage units from 6:00AM – 10:00PM (365 days per year), and some of our facilities provide 24-hour access. Customers have responsibility for moving their items intoexisting portfolio. We execute our external growth strategy by developing, redeveloping, acquiring and out of their units. Self storage unit sizes typically range from five feet by five feet to 10 feet by 30 feet.

Self storage provides a convenient way for individuals and businesses to store their possessions, whether due to a life change or simply because of a need for extra storage space. According to the 2020 Self Storage Almanac,managing self storage facilities generally have a customer mixin the United States and Canada both internally and through our Managed REITs, and we look to acquire properties that are physically stabilized, recently developed, in various stages of approximately 79% residential, 14% commercial, 4% military and 3% students. The mixlease up or at certificate of residential customers using a self storage property is determined by a property’s local demographics and often includes people who are lookingoccupancy. We seek to downsize their living space or whoacquire undermanaged facilities that are not yet settled in a large home. The items that residential customers place in self storage properties range from furniture, household itemsoperated by institutional operators, where we can implement our proprietary management and appliancestechnology to cars, boats and recreational vehicles. Commercial customers tend to include small business owners who require easy and frequent access to their goods, records or extra inventory, or storage for seasonal goods. Self storage properties provide an accessible storage alternative at a relatively low cost. Properties generally have on-site managers who supervise and run the day-to-day operations, providing customers with assistance as needed.

The six key demand drivers of self storage are: (1) population growth; (2) percentage of renter-occupied housing units; (3) average household size; (4) average household income; (5) supply constraints; and (6) economic growth. Customers choose a self storage property based largely on the convenience of the site to their home or business. Therefore, high-density, high-traffic population centers are ideal locations for a self storage property. A property’s perceived security and the general

5

professionalism of the site managers and staff are also contributing factors to a site’s ability to secure rentals. Although most self storage units are leased to customers on a month-to-month basis, customers tend to continue their leases for extended periods of time. However, there are seasonal fluctuations in occupancy rates for self storage properties. Generally, there is increased leasing activity at self storage properties during the late spring and early summer months due to the higher number of people who relocate during this period.

As population densities have increased in the U.S., there has been an increase in self storage awareness and development. According to the 2020 Self Storage Almanac:

The growth in the industry has created more competition in various geographic regionsand the extent of competition in a market area depends significantly on local market conditions. This has led to an increased emphasis on site location, property design, rental rates, innovation and functionality to accommodate local planning and zoning boards and to distinguish a facility from other offerings in the market. This is especially true for new sites slated for high-density population centers. We believe we will compete successfully on these bases. However, many of our competitors are larger and have substantially greater resources than we do. Such competitors may, among other possible advantages, be capable of paying higher prices for acquisitions and obtaining financing on better terms than us.

Self storage operators have placed increased emphasis on offering ancillary products that provide incremental revenues. Moving and packing supplies, such as locks and boxes, and the offering of other services, such as tenant insurance, protection or insurance plans, or other indemnity programs and truck rentals, help to increase revenues. As more sophisticated self storage operators continue to develop innovative products and services such as online rentals, 24-hour accessibility, digital gate access and unit security, climate-controlled storage, wine storage, customer-service call center access and after-hours storage, local operators may be increasingly unable to meet higher customer expectations, which could encourage consolidation in the industry.

We also believe that the self storage industry possesses attractive characteristics not found in other commercial real estate sectors, including the following:

Industry Segments

Prior to the Self Administration Transaction on June 28, 2019, we internally evaluated all of our properties and interests therein as one industry segment and, accordingly, did not report segment information.

Subsequent to the Self Administration Transaction, we now operate in two reportable business segments: (i) self storage operations and (ii) our Managed REIT Platform business.

Management evaluates performance based uponmaximize net operating income (“NOI”). For our self storage operations, NOI is defined as leasing and related revenues, less property level operating expenses. NOI for the Company’s Managed REIT Platform business represents Managed REIT Platform revenues less Managed REIT Platform expenses.

General Business Strategiesincome.

We acquire, own and operate self storage facilities—including facilities owned by us as well as those owned by our Managed REITs. We are also continually looking for investment opportunities to grow our business in a way that achieves our investment objectives.

Operational

As an operating business, self storage requires a much greater focus on strategic planning and tactical operation plans. Our in-house salescall center allows us to centralize our sales efforts as we capture new business over the phone, email, web-based chat, and text mediums. As we have grown our portfolio of self storage facilities, we have been able to consolidate and streamline a number of aspects of our operations through economies of scale. For example, our size and geographic diversification, as well as institution ofwe have implemented a blanket property and casualty insurance program over all properties owned or managed by us nationwide which, coupled with our size and geographic diversification, reduces our total insurance costs per property. We also utilize our digital marketing breadth and expertise which allows us to acquire customers efficiently by leveraging our portfolio size and technological proficiency. To the extent we acquired facilities in clusters within geographic regions, we see property management efficiencies resulting in reduction of personnel and other administrative costs.

As discussed herein, we, through our subsidiaries, currently serve as the sponsor of SST VI and SSGT III. We also served as the sponsor of Strategic Storage Trust IV, Inc., a public non-traded REIT (“SST IV”) through March 17, 2021, and Strategic Storage Growth Trust II, Inc., a private REIT (“SSGT II”) through June 1, 2022. Prior to March 17, 2021 and June 1, 2022, SST IV and SSGT II, respectively, were also included in the “Managed REITs.” We operate the properties owned by the Managed REITs, which together with one other self storage property we manage consist of, as of December 31, 2023, 32 operating properties and approximately 25,400 units and approximately 2.8 million rentable square feet. In addition, we have the internal capability to originate, structure and manage additional self storage investment programs (the “Managed REIT Platform”) which would be sponsored by SmartStop REIT Advisors, LLC (“SRA”), our indirect subsidiary. We generate asset management fees, property management fees, acquisition fees, and other fees and also receive substantially all of the tenant protection program revenue earned by our Managed REITs. For the property management and advisory services that we provide, we are reimbursed for certain expenses that otherwise helps to offset our net operating expense burden.

Investment Objectives

We focus on investing in self storage facilities and related self storage real estate investments that are expected to support sustainable stockholder distributions over the long term. Our primary investment objectives are to: (1) invest in real property in a manner that allows us to qualify as a REIT for U.S. federal income tax purposes; (2) provide regular cash distributions to our stockholders; (3) preserve and protect our stockholders’ invested capital; (4) achieve appreciation in the value of our properties over the long term; and (5) grow net cash flow from operations in order to provide sustainable cash distributions to our stockholders over the long-term.

Our management team has experience acquiring self storage facilities across a broad spectrum of opportunities including physically stabilized facilities, recently developed facilities in physical or economic lease up, facilities that have just received a certificate of occupancy ("C/O"), facilities in need of renovation and/or re-development and ground up development. We have adopted an investment allocation policy, pursuant to which we will have first priority for investment opportunities, and if we decline any such opportunity, we will allocate it to another program sponsored by us after considering various factors. In considering and evaluating potential acquisition opportunities, and to augment our seasoned acquisition team, we employ our proprietary underwriting methodology. We believe that we maintain a competitive advantage in acquiring facilities given the scale of our business and the experience and industry relationships of our team. We maintain a network of self storage operators, real estate brokers and other market participants in the U.S. and Canada, which gives us unique insight into new and highly desirable acquisition opportunities.

Liquidity Events

Subject to then-existing market conditions, and in the sole discretion of our board of directors, we intend to seek one or more of the following liquidity events within the next few years: (1) list our shares on a national securities exchange; (2) merge, reorganize or otherwise transfer our company or its assets to another entity with listed securities; (3) commence the sale of all of our properties and liquidate our company; or (4) otherwise create a liquidity event for our stockholders. Notwithstanding the foregoing, there is no requirement for us to complete one of these liquidity events and our board of directors has the sole discretion to continue operations indefinitely if it deems such continuation to be in the best interests of our stockholders.

Joint Ventures

We may enter into joint ventures, general partnerships, co-tenancies and other participations with real estate developers, owners and others for the purpose of owning and leasing real properties. Among other reasons, we may want to acquire properties through a joint venture with third parties or affiliates in order to diversify our portfolio of properties in terms of geographic region or property type or to co-invest with one of our property management partners. Joint ventures may also allow us to acquire an interest in a property without requiring that we fund the entire purchase price. In addition, certain properties may be available to us only through joint ventures. For example, in connection with the Self Administration Transaction (as defined below), we acquired a joint venture arrangement with SmartCentres Real Estate Investment Trust, an unaffiliated third party (“SmartCentres”), pursuant to which we and SmartCentres work together to identify primarily self storage development opportunities in certain regions in Canada. In general, we have historically participated in these opportunities through one of our Managed REITs on a 50/50 basis with SmartCentres; however, we have several current purchase and sale agreements related to properties which may be acquired pursuant to the SmartCentres joint venture arrangement. Additionally, as discussed in Item 1 herein, onOn March 17, 2021, we closed onacquired six SmartCentres joint venture properties in the SST IV Merger whereby(as defined below). On June 1, 2022, we acquired 6three SmartCentres joint ventures in the SSGT II Merger (as defined below). Additionally, on May 25, 2022, we, as 50% owner and SmartCentres as the other 50% owner of a joint venture properties. Historically,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, acquired a parcel of land in Whitby, Ontario (the "Whitby Property"), that we and SmartCentres intend to develop into a self storage facility in the future. Generally, SmartCentres has been responsible for the development of the properties and we have been responsible for the operation of the facilities upon completion. For more information, please see Note 3—4 – Investments in Unconsolidated Real Estate FacilitiesVentures of the Notes to the Consolidated Financial Statements.

Equity

The Company was formed on January 8, 2013, under the Maryland General Corporation Law. 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”), marketed and sold primarily through retail investor channels, including the independent broker dealer channel. At the termination of our Offering in January 2017, we had sold approximately 48 million Class A Shares and approximately 7 million shares of Class T common stock ("Class T Shares") for approximately $493 million and $73 million respectively.

In November 2016, we filed with the SEC a Registration Statement on Form S-3, which registered up to an additional $100.9 million in shares under our distribution reinvestment plan (our “DRP Offering”). The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. As of December 31, 2023, we had sold approximately 7.2 million Class A Shares and approximately 1.0 million Class T Shares for approximately $77.8 million and $11.1 million, respectively, in our DRP Offering.

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 shares (the aggregate shares to be purchased, the “Preferred Shares”) of our newly-created 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.

Net Asset Value

On January 15, 2024, our board of directors, includingupon recommendation of our Nominating and Corporate Governance Committee, approved an estimated net asset value per share 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.

Recent Economic Conditions

Broad economic weakness, inflationary pressures, rising interest rates, geopolitical events, and other economic events could adversely impact our business, financial condition, liquidity and results of operations. However, the extent and duration to which our operations may be impacted is highly uncertain and cannot be predicted.

Industry and Competition

Self storage refers to properties that offer month-to-month storage unit rental for personal or business use. Self storage facilities offer a cost-effective and flexible storage alternative in which customers rent fully enclosed and secure spaces. Typical unit sizes range from 5x5 feet to 10x30 feet with facilities typically providing a variety of different sizes and configurations. Customers typically have access to their storage units 18 hours a day, with some facilities offering 24-hour access. Rental rates can vary and are determined by the location and size of the rental space, the level of security, and whether the unit is climate controlled. The short-term nature of self storage leases creates the opportunity for real-time rate increases, which has led well-positioned facilities to achieve substantial rate growth in a rising cost environment.

In addition to primary self storage operations, facilities also tend to have a number of other ancillary products that provide incremental revenues. This includes, but is not limited to, tenant insurance, protection or insurance plans, moving and packing supplies, locks and boxes, and other services. Sophisticated operators have the opportunity to substantially increase profitability of under-managed facilities post acquisition.

The customer base of self storage operators includes both local residential customers, typically within a 3- to 5-mile radius of the facility, as well as commercial users. According to the 2023 Self Storage Almanac, self storage facilities generally have a customer mix of approximately 79% residential, 14% commercial, 4% military and 3% students.

The self storage industry is highly fragmented, with owners and operators ranging from individual property owners to institutional investors and large, publicly traded REITs. According to the 2023 Self Storage Almanac, there are approximately 51,000 primary self storage facilities in the U.S. representing a total of 2.0 billion rentable square feet. The largest 100 operators manage approximately 59% of net rentable square footage, but only 35% of all U.S.-based self storage properties. The five publicly listed self storage companies are Public Storage, Extra Space Storage Inc., AMERCO (the parent company of U-Haul), CubeSmart, and National Storage Affiliates Trust, which collectively operate approximately 22% of all U.S.-based self storage properties. Similar to the U.S., the self storage market in Canada exhibits highly fragmented ownership, albeit to a much greater extent. Colliers estimates that approximately 70% of all stores in Canada are owned by individuals with only one or two stores and the top 10 operators in Canada have roughly 20% market share. With the majority of our independent directors, we will attempt to obtain a right of first refusal or option to buy if such venture partner elects to sell its interestthe existing supply operated locally by non-institutional groups in the joint venture entity orU.S and Canada, there is a significant market opportunity to acquire existing facilities and increase revenue and profitability through professional management, digitalization and physical expansion projects.

Industry Segments

In the event that the venture partner were to elect to sell property held in any such joint venture, however,Self Administration Transaction on June 28, 2019, we may not have sufficient funds to exercise our right of first refusal to buy the venture partner’s interest in the property held by the joint venture.

Liquidity Events

Subject to then-existing market conditions, and in the sole discretion of our board of directors, we intend to seek one or more of the following liquidity events within the next few years: (1) merge, reorganize or otherwise transfer our company or

its assets to another entity with listed securities; (2) commence the sale ofinternally evaluated all of our properties and liquidateinterests therein as one industry segment and, accordingly, did not report segment information.

Subsequent to the Self Administration Transaction, we now operate in two reportable business segments: (i) self storage operations and (ii) our company; (3) listManaged REIT Platform business.

Management evaluates performance based upon net operating income (“NOI”). For our shares on a national securities exchange; or (4) otherwise create a liquidity eventself storage operations, NOI is defined as leasing and related revenues, less property level operating expenses. NOI for our stockholders. Notwithstanding the foregoing, there is no requirement for us to complete one of these liquidity events and our board of directors has the sole discretion to continue operations indefinitely if it deems such continuation to be in the best interests of our stockholders.Company’s Managed REIT Platform business represents Managed REIT Platform revenues less Managed REIT Platform expenses.

Government Regulations

Our business is subject to many laws and governmental regulations. Changes in these laws and regulations, or their interpretation by agencies and courts, occur frequently.

Accommodations for Persons with Disabilities

We are subject to various rules, regulations and standards with respect to accommodations we must make for individuals with disabilities. For example, in the United States, under the Americans with Disabilities Act of 1990, or ADA, all public accommodations and commercial facilities are required to meet certain federal requirements related to access and use by disabled persons. We are also subject to similar requirements in Ontario, Canada, under the Accessibility for Ontarians with Disabilities Act, or AODA. Complying with such requirements could require us to remove access barriers. Failing to comply could result in the imposition of fines by various governmental agencies or an award of damages to private litigants. Although we intend to acquire properties that substantially comply with these requirements, we may incur additional costs related to compliance. In addition, a number of additional governmental laws may require us to modify any properties we purchase, or may restrict further renovations thereof, with respect to access by disabled persons. Additional legislation could impose financial obligations or restrictions with respect to access by disabled persons. Although we believe that these costs will not have a material adverse effect on us, if required changes involve a greater amount of expenditures than we currently anticipate, our ability to make distributions to our stockholders could be adversely affected.

Environmental Matters

Under various federal, state and local laws, ordinances and regulations, a current or previous owner or operator of real property may be held liable for the costs of removing or remediating hazardous or toxic substances. These laws often impose clean-up responsibility and liability without regard to whether the owner or operator was responsible for, or even knew of, the presence of the hazardous or toxic substances. The costs of investigating, removing or remediating these substances may be substantial, and the presence of these substances may adversely affect our ability to rent units or sell the property, or to borrow using the property as collateral, and may expose us to liability resulting from any release of or exposure to these substances. If we arrange for the disposal or treatment of hazardous or toxic substances at another location, we may be liable for the costs of removing or remediating these substances at the disposal or treatment facility, whether or not the facility is owned or operated by us. We may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from a site that we own or operate. Certain environmental laws also impose liability in connection with the handling of or exposure to asbestos containing materials, pursuant to which third parties may seek recovery from owners or operators of real properties for personal injury associated with asbestos-containing materials and other hazardous or toxic substances.

Other Regulations

The properties we acquire will be subject to various federal, state and local regulatory requirements, such as zoning and state and local fire and life safety requirements. Failure to comply with these requirements could result in the imposition of fines by governmental authorities or awards of damages to private litigants. We intend to acquire properties that are in material compliance with all such regulatory requirements. However, we cannot make assurances that these requirements will not be changed or that new requirements will not be imposed which would require significant unanticipated expenditures by us and could have an adverse effect on our financial condition and results of operations.

Employees and Human Capital

As of December 31, 2020,2023, we had approximately 400500 employees, none of which are represented by a collective bargaining agreement. We continually assess and strive to enhance employee satisfaction and engagement. We believe our relationship with our employees is good and that we provide them with adequate flexibility to meet personal and family needs. We also appreciate the importance of retention, growth and development of our employees and we believe we offer competitive compensation (including salary and bonuses) and benefits packages to our employees. Further, from professional

8

development opportunities to leadership training, we have development programs and on-demand opportunities to cultivate talent throughout our organization.

WhileWe strive to foster an inclusive work environment, comprising top talent and high performing employees. We maintain policies that strive to protect our criteria for recruitment, hiring, development, training, compensation and advancement are based on qualifications, performance, skills and experience, we are growing our focus on diversity and inclusion strengths and opportunities and evaluating strategies to support further progress in that area. We also endeavor to maintain workplaces that are freeemployees from discrimination or harassment on the basis of color, race, sex, national origin, ethnicity, religion, age, disability, sexual orientation, gender identification or expression or any other status protected by applicable law. To that end, we conduct annual training to raise awareness of (and with the goal of preventing) all forms of harassment and discrimination.

For a discussion of additional measures taken by us with respect to our employees in response to the COVID-19 pandemic, see the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Market Conditions,” below.

9ITEM 1A.RISK FACTORS

Below are risks and uncertainties that could adversely affect our operations that we believe are material to stockholders. Additional risks and uncertainties not presently known to us or that we do not consider material based on the information currently available to us may also harm our business. Unless the context otherwise requires, references to stockholders are generally intended to be references to our common stockholders.

Risks Related to an Investment in SmartStop Self Storage REIT, Inc.

We have historically incurred a net loss to date andlosses, have an accumulated deficit, and weit is possible that our operations may not be profitable, or maintain profitability, in the future.

We incurredrecorded a net loss attributable to our common stockholders of approximately $54$2.7 million for the fiscal year ended December 31, 2020.2023. We have historically incurred net losses attributable to our common stockholders and cannot guarantee that we will not incur future operating losses. Our accumulated deficit was approximately $141$167.3 million as of December 31, 2020. The extent of our future operating losses and the timing of when we will achieve profitability are uncertain, and we may never achieve or sustain profitability.2023.

We have paid, and may continue to pay, distributions from sources other than cash flow from operations; therefore, we will have fewer funds available for the acquisition of properties, and our stockholders’ overall return may be reduced.

Our

In the future we may borrow funds, issue additional securities, or sell assets in order to fund the distributions or make the distributions out of proceeds from our DRP.distributions. We are not prohibited from undertaking such activities by our charter, bylaws or investment policies, and we may use an unlimited amount from any source to pay our distributions. For the year ended December 31, 2020, we funded 54% of our distributions using cash flows from operations, 14% using cash provided by financing activities, and 32% using proceeds from our DRP Offering. If we fund distributions from financings, then such financings will need to be repaid, and if we fund distributions from operatingsources other than cash flows,flow from operations, then we will have fewer funds available for acquisition of properties or working capital, which may affect our ability to generate future cash flows from operations and may reduce our stockholders’ overall returns. Additionally, to the extent distributions exceed cash flow from operations, a stockholder’s basis in our stock may be reduced and, to the extent distributions exceed a stockholder’s basis, the stockholder may recognize a capital gain.

There is currently no public trading market for our shares and there may never be one; therefore, it will be difficult for our stockholders to sell their shares. Our charter does not require us to pursue a liquidity transaction at any time.

There is currently no public market for our shares and there may never be one. Stockholders may not sell their shares unless the buyer meets applicable suitability and minimum purchase standards. Our charter also prohibits the ownership by any one individual of more than 9.8% of our stock, unless waived by our board of directors, which may inhibit large investors from desiring to purchase our stockholders’ shares. As described below, our share redemption program is partially suspended. If we lift suchthe suspension of our share redemption program, stockholders will continue to be limited in terms of the amount of shares which may be redeemed. Therefore, it may be difficult for our stockholders to sell their shares promptly or at all. If our stockholders are able to sell their shares, they will likely have to sell them at a substantial discount to the price they paid for the shares.discount. It also is likely that the shares would not be accepted as the primary collateral for a loan. Our stockholdersshares should purchase shares onlybe considered as a long-term investment because of the illiquid nature of the shares.

10

Our share redemption program is partially suspended, and even if stockholders are able to have their shares redeemed, our stockholders may not be able to recover the amount of their investment in our shares.

Presently, our share redemption program is suspended except for redemption requests related to the death or disability of such stockholder (including redemption due to confinement to a long-term care facility), or other exigent circumstances.

If our share redemption program is reinstated or a common stockholder is otherwise able to have their shares redeemed, such stockholders should be fully aware that our share redemption program contains significant restrictions and limitations.

Further, our board of directors may limit, suspend, terminate or amend any provision of the share redemption program upon 30 days’ notice. Redemptions of shares, when requested, will generally be made quarterly to the extent we have sufficient funds available to us to fund such redemptions. 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 and redemptions will be funded solely from proceeds from our distribution reinvestment plan. We are not obligated to redeem shares under our share redemption program. Therefore, our common stockholders should not assume that they will be able to sell any of their shares back to us pursuant to our share redemption program at any time or at all.

The purchase price for shares we repurchase under our share redemption program is equal to the most recently published estimated net asset value per share of the applicable share class. Accordingly, our common stockholders may receive less by selling their shares back to us than they would receive if our investments were sold for their estimated values and such proceeds were distributed in our liquidation.

We have issued Series A Convertible Preferred Stock that ranks senior to all common stock and grants the holder superior rights compared to common stockholders, which may have the effect of diluting our stockholders’ interests in us and discouraging a takeover or other similar transaction.

We have issued Series A Convertible Preferred Stock that ranks senior to all other shares of our stock, including our common stock, and grants the holder (the “Preferred Investor”) certain rights that are superior to the rights of common stockholders, including with respect to the payment of distributions, liquidation preference, redemption rights, and conversion rights.

Distributions on the Series A Convertible Preferred Stock are cumulative and are declared and payable quarterly in arrears. We are obligated to pay the Preferred Investor its current distributions and any accumulated and unpaid distributions prior to any distributions being paid to our common stockholders and, therefore, any cash available for distribution is used first to pay distributions to the Preferred Investor. If we fail to pay distributions on the Series A Convertible Preferred Stock for four quarters (whether or not consecutive), the Preferred Investor is permitted to vote on any matter submitted to a vote of the common stockholders of the Company, upon which the Preferred Investor and common stockholders shall vote together as a single class. In such a case, the Preferred Investor’s vote would have a dilutive effect on the voting power of our common stockholders.

The Series A Convertible Preferred Stock has a liquidation preference in the event of our voluntary or involuntary liquidation, dissolution, or winding up of our affairs (a “liquidation”) which could negatively affect any payments to the common stockholders in the event of a liquidation. Furthermore, the Series A Convertible Preferred Stock is redeemable in certain circumstances. A redemption of our Series A Convertible Preferred Stock, whether at our option or at the option of the holder of our Series A Convertible Preferred Stock, could have an adverse effect on our financial condition, cash flow and the amount available for distributions to our common stockholders.

The Preferred Investor also has, upon the occurrence of certain events, the right to convert any or all of the Series A Convertible Preferred Stock held by the Preferred Investor into shares of our common stock. The issuance of common stock upon conversion of the Series A Convertible Preferred Stock would result in dilution to our common stockholders. As of December 31, 2020,2023, we had $200 million of Series A Convertible Preferred Stock outstanding, which would represent approximately 24%16% of our common stock on an as converted, fully diluted basis. See Note 8,6 – Preferred Equity, of the Notes to the Consolidated Financial Statements, for more information.

11

The Series A Convertible Preferred Stock also imposes several negative covenants on us such as not permitting us to exceed a leverage ratio of 60% loan-to-value or prohibiting us from entering into a merger with another entity whose assets are not at least 80% self storage related, in each case without an affirmative vote by the Preferred Investor. Because of these superior rights, the existence of the Series A Convertible Preferred Stock could have the effect of discouraging a takeover or other transaction in which holders of some or a majority of our outstanding common stock might receive a premium for their shares.

We may only calculate the estimated value per share for our shares annually and, therefore, our stockholders may not be able to determine the estimated net asset value of their shares on an ongoing basis.

On April 20, 2020,January 15, 2024, our board of directors approved an estimated value per share for our Class A shares and Class T shares of $10.40.$15.25. Our board of directors approved this estimated value per share pursuant to rules promulgated by FINRA. When determining the estimated value per share there are currently no SEC, federal andor state rules that establish requirements specifying the methodology to employ in determining an estimated value per share; provided, however, that the

determination of the estimated value per share must be conducted by, or with the material assistance or confirmation of, a third-party valuation expert or service and must be derived from a methodology that conforms to standard industry practice.

We calculated our estimated value per share as of December 31, 2019, which was prior to the emergence of the novel coronavirus (“COVID-19”) in the United States.  At the time the estimated value per share was calculated, we were unable to quantify the potential impact of the COVID-19 pandemic, and therefore the estimated value per share did not take into account the impact of the pandemic on our operations or the broader economic environment.  Future valuations of our properties or other assets and liabilities could be affected by COVID-19 or any associated weakened economic conditions.  We intend to use this estimated per share value of our shares until the next net asset valuation approved by our board of directors, which we are required to approve at least annually. We may not calculate the net asset value per share for our shares more than annually. Therefore, you may not be able to determine the net asset value of your shares on an ongoing basis.

In determining our estimated value per share, we primarily relied upon a valuation of our portfolio of properties as of December 31, 2019.September 30, 2023. Valuations and appraisals of our properties are estimates of fair value and may not necessarily correspond to realizable value upon the sale of such properties; therefore our estimated net asset value per share may not reflect the amount that would be realized upon a sale of each of our properties.

For the purposes of calculating the estimated value per share, an independent third party appraiser valued our properties as of December 31, 2019.September 30, 2023. The valuation methodologies used to value our properties involved certain subjective judgments. Ultimate realization of the value of an asset depends to a great extent on economic and other conditions beyond our control and the control of our independent appraiser. Further, valuations do not necessarily represent the price at which an asset would sell, since market prices of assets can only be determined by negotiation between a willing buyer and seller. Therefore, the valuations of our properties and our investments in real estate related assets may not correspond to the timely realizable value upon a sale of those assets. Because our share prices are primarily based on the estimated net asset value per share, our stockholders may pay more than realizable value when such shares are purchased or receive less than realizable value when such shares are sold.

We may be unable to pay or maintain cash distributions or increase distributions over time.

There are many factors that can affect the availability and timing of cash distributions to stockholders. We are required to pay dividends with respect to our Series A Convertible Preferred Stock at rate of 6.25% per annum,. which is subject to increases following the fifth anniversary of the Series A Convertible Preferred Stock issuance. Distributions to our common stockholders will be based principally on distribution expectations of our investors and cash available from our operations.

The amount of cash available for distribution will be affected by many factors, such as the yields on securities of other real estate programs that we invest in and our operating expense levels, as well as many other variables. Actual cash available for distribution may vary substantially from estimates. We cannot assure our stockholders that we will be able to pay or maintain distributions or that distributions will increase over time, nor can we give any assurance that rents from the properties will increase, that the securities we buy will increase in value or provide constant or increased distributions over time, or that future acquisitions of real properties will increase our cash available for distribution to stockholders. We also cannot assure our stockholders that our board of directors will not decide to reduce distributions based on other external factors. Additionally, our board of directors may decide to amend our distribution policy to provide for distributions on a quarterly basis instead of a monthly basis. Our actual results may differ significantly from the assumptions used by our board of directors in establishing the distribution rate to stockholders. If we fail to pay distributions on the Series A Convertible Preferred Stock for four quarters (whether or not consecutive), the Preferred Investor is permitted to vote on any matter submitted to a vote of the common stockholders of the Company, upon which the Preferred Investor and common stockholders shall vote together as a single class. In such a case, the Preferred Investor’s vote would have a dilutive effect on the voting power of our common stockholders.

If we lose or are unable to retain our executive officers, our ability to implement our investment objectivesbusiness could be delayed or hindered, which could adversely affect our ability to continue to pay distributions and the value of our stockholders’ investment.harmed.

Our success depends to a significant degree upon the contributions of our executive officers. While we have adopted an Executive Severance and Change of Control Plan which is applicable to each of these officers, we do not have an employment agreement with any of these key personnel and we cannot guarantee that all, or any particular one, will remain employed by us. If any of these executive officers were to cease their affiliation with us, our operating results could suffer. If we lose or are unable to retain our executive officers, or do not establish or maintain appropriate strategic relationships, our ability to implementoperating results and our investment strategiesfuture growth could be delayed or hindered, which could adversely affect our ability to continue to pay distributions at the current rate and the value of our stockholders’ investment.suffer.

Our Executive Severance and Change of Control Plan and the related agreements with our executive officers may result in significant expense for us and may deter a third party from engaging in a change of control transaction with us.us that might otherwise result in a premium price to our stockholders.

We have adopted an Executive Severance and Change of Control Plan that is applicable to our executive officers and have entered into an associated Severance Agreement with each of our executive officers. Pursuant to such documents, if the officer’s employment is terminated other than for cause or if the officer elects to terminate his employment with us for good reason, we will make a severance payment equal to the officer’s highest annual compensation in the prior two years plus the officer’s average cash performance bonus earned for the prior three years, multiplied by an amount specified in the Executive Severance and Change of Control Plan, together with continuation of medical coverage for a period of time specified in the Executive Severance and Change of Control Plan. In addition, certain outstanding equity awards may be subject to accelerated vesting or may remain eligible for vesting, as specified further in the Executive Severance and Change of Control

Plan. These agreements may result in a significant expense for us if an executive officer’s employment is terminated for certain reasons, and may discourage a third party from acquiring us.engaging in a change of control transaction with us that might otherwise result in a premium price for our stockholders.

Impairment of goodwill or other intangible assets resulting from the Self Administration Transaction may adversely affect our financial condition and results of operations.

During 2020, with the emergence of the COVID-19 Pandemic and the resulting volatility and disruptions of the economy and capital markets, and the ability of our Managed REITs to raise additional equity in light of the foregoing, we recorded various impairments to goodwill and other intangible assets, related to our Managed REITs. Potential impairmentadditional future impairments of goodwill or other intangible assets, including trademarks and other acquired intangibles, resulting from the Self Administration Transaction could adversely affect our financial condition and results of operations. We assess our goodwill and other intangible assets and long-lived assets for impairment at least annually or upon the occurrence of a triggering event, as required by GAAP. We are required to record an impairment charge if circumstances indicate that the asset carrying values exceed their fair values. Our assessment of goodwill, other intangible assets, or long-lived assets could indicate that an impairment of the carrying value of such assets may have occurred that could result in a material, non-cash write-down of such assets, which could have a material adverse effect on our results of operations and future earnings. See Note 5—Self Administration Transaction - Intangibles, Goodwill,

If we fail to maintain an effective system of internal control over financial reporting and Certain Other Assetsdisclosure controls, we may not be able to accurately and Liabilitiestimely report our financial results.

Effective internal control over financial reporting and disclosure controls are necessary for us to provide reliable financial reports, effectively prevent fraud, and to operate successfully as a public company. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results could be harmed. We are currently required to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, and, in the future, if we were to become an accelerated filer or large accelerated filer, we may be required to have our independent registered public accounting firm attest to the Notessame, as required by Section 404 of the Sarbanes-Oxley Act of 2002. To date, the audit of our consolidated financial statements by our independent registered public accounting firm has included a consideration of internal control over financial reporting as a basis of designing their audit procedures, but not for the purpose of expressing an opinion (as is required pursuant to Section 404(b) of the Consolidated Financial Statements for additionalSarbanes-Oxley Act of 2002) on the effectiveness of our internal control over financial reporting. If a material weakness or significant deficiency was to be identified in our internal control over financial reporting, we may also identify deficiencies in some of our disclosure controls and procedures that we believe require remediation. If we or our independent registered public accounting firm discover deficiencies or weaknesses, we will make efforts to improve our internal controls over financial reporting and disclosure controls. However, there is no assurance that we will be successful. Any failure to maintain effective controls or timely effect any necessary improvement of our internal controls over financial reporting and disclosure controls could harm operating results or cause us to fail to meet our reporting obligations. Ineffective internal control over financial reporting and disclosure controls could also cause investors to lose confidence in our reported financial information.

Our trademarks are important.important, and the loss of or our inability to enforce trademark and other proprietary intellectual property rights could harm our business.

We own trademarks and other intellectual property rights, including but not limited to the “SmartStop®” and “Strategic Storage®” brands, which are important to our success and competitive position, and the loss of or our inability to enforce trademark and other proprietary intellectual property rights could harm our business. We will devote substantial resources to the establishment and protection of our trademarks and other proprietary intellectual property rights.

Our efforts to protect our intellectual property may not be adequate. Third parties may misappropriate or infringe on our intellectual property. From time to time, we may engage in litigation to protect our intellectual property, which could result in substantial costs as well as diversion of management attention. The occurrence of any of these risks could adversely affect our business and results of operations. See Note 5—Self Administration Transaction - Intangibles, Goodwill, and Certain Other Assets and Liabilities to the Notes to the Consolidated Financial Statements for additional information.

We recently became a self-managed REIT and have limited operating experience being self-managed.

As a result of the Self Administration Transaction, we are a newly self-managed REIT. We no longer bear the costs of the various fees and expense reimbursements previously paid to our former external advisor and its affiliates; however, our expenses now include the compensation and benefits of our officers and employees, as well as overhead previously paid by our former external advisor and its affiliates. Our employees now provide services historically provided by the external advisors and their affiliates. We are subject to potential liabilities that are commonly faced by employers, such as workers’ disability and compensation claims, potential labor disputes, and other employee-related liabilities and grievances, and we

13

bear the cost of the establishment and maintenance of any employee compensation plans. In addition, prior to June 28, 2019, we had not previously operated as a self-managed REIT and may encounter unforeseen costs, expenses, and difficulties associated with providing these services on a self-advised basis. If we incur unexpected expenses as a result of our self-management, our results of operations could be more negatively impacted than they otherwise would have been.

Strategic Transfer Agent Services, LLC, our Transfer Agent, has a limited operating history and a failure by our Transfer Agent to perform its functions for us effectively may adversely affect our operations.

Our Transfer Agent is a related party. While it is a registered transfer agent with the SEC, the business was formed in October 2017 and has had only limited operations to date. Because of its limited experience, there is no assurance that our Transfer Agent will be able to effectively provide transfer agent and registrar services to us. Furthermore, our Transfer Agent

will be responsible for supervising third party service providers who may, at times, be responsible for executing certain transfer agent and registrar services. If our Transfer Agent fails to perform its functions for us effectively, our operations may be adversely affected.

Our cash could be adversely affected if the financial institutions in which we hold our cash fail.

We maintain domestic cash deposits in Federal Deposit Insurance Corporation ("FDIC") insured banks and in money market accounts. Our balances may exceed FDIC insurance limits or may otherwise not be subject to FDIC coverage. Our balances could be impacted if one or more of the financial institutions in which we deposit monies fails or is subject to other adverse conditions in the financial or credit markets. We can provide no assurance that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial and credit markets.

Our bylaws designate the Circuit Court for Baltimore City, Maryland as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Circuit Court for Baltimore City, Maryland, or, if that Court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, shall be the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders with respect to our Company, our directors, our officers, or our employees. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that the stockholder believes is favorable for disputes with us or our directors, officers, or employees, which may discourage meritorious claims from being asserted against us and our directors, officers, and employees. Alternatively, if a court were to find this provision of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, or results of operations.

Our future results may suffer as a result of the effect of recent affiliated mergers, acquisitions and other strategic transactions.

We consummated the SSGT Mergers in January 2019 and recently consummated the SST IV Merger onin March 17, 2021.2021 and the SSGT II Merger in June 2022. We will likely continue to expand our operations through additional mergers, acquisitions and other strategic transactions, including such transactions with affiliated real estate programs or Managed REITs, some of which may involve complex challenges. Our future success will depend, in part, upon the merger consideration negotiated by our special committees appointed by our board of directors in connection with these affiliated mergers, our ability to manage our expansion opportunities, integrate new operations into our existing business in an efficient and timely manner, successfully monitoring our operations, costs and service quality, and maintaining other necessary internal controls. There can be no assurance that our expansion or acquisition opportunities will be successful, or that we will realize our expected operating efficiencies, cost savings, revenue enhancements, synergies, or other benefits. Moreover, we assumed the liabilities of SSGT and SST IV and SSGT II in connection with the respective mergers. These liabilities could have a material adverse effect on our business to the extent we have not identified such liabilities or have underestimated the amount of such liabilities.

We are the subject of various claims and legal proceedings and may become the subject of claims, litigation or investigations which could have a material adverse effect on our business, financial condition or results of operations.

In the ordinary course of business, we are the subject of various claims and legal proceedings and may become the subject of claims, litigation or investigations, including commercial disputes and employee claims, such as claims of age discrimination, sexual harassment, gender discrimination, immigration violations or other local, state and federal labor law violations, and from time to time may be involved in governmental or regulatory investigations or similar matters arising out of our current or future business. While we have policies in place that are intended to prevent or address such issues, we cannot be assured that such policies will adequately prevent or mitigate the foregoing concerns and any associated harm. Any claims asserted against us or our management, regardless of merit or eventual outcome, could harm our reputation or the reputation of our management and have an adverse impact on our relationship with our clients, business partners and other third parties and could lead to additional related claims. In light of the potential cost and uncertainty involved in litigation, we have in the past settled and may in the future settle matters even when we believe we have a meritorious defense. Certain claims may seek injunctive relief, which could disrupt the ordinary conduct of our business and operations or increase our cost of doing business. Our insurance or indemnities may not cover all claims that may be asserted against us. Furthermore, there is no guarantee that we will be successful in defending ourselves in pending or future litigation or similar matters under various laws. Any judgments or settlements in any pending litigation or future claims, litigation or investigation could have a material adverse effect on our business, financial condition and results of operations.

Privacy concerns could result in regulatory changes that may harm our business.

The California Consumer Privacy Act (the “CCPA”) went into effect on January 1, 2020. Additionally, an amendment to the CCPA, the California Privacy Rights Act (the “CPRA”) went into effect on January 1, 2023, with a lookback to January 1, 2022. While the CPRA modifications are not finalized, the current proposed amendment significantly modifies the CCPA and imposes additional data protection obligations on companies doing business in California. The CCPA, as amended

by the CPRA, is intended to protect consumer privacy rights, and, among other things, it providesprovide California residents with the ability to know what information companies collect about them, to request, in certain circumstances, the deletion of such information, and to affirmatively opt out of the sale or “sharing” of their personal information. However, regulations fromWe cannot yet predict the California Attorney General have not been finalized, and it is expected that additional amendments tofull impact of the CCPA, will be introduced in 2020.  It therefore remains unclear what, ifas amended by the CPRA, or any modifications will be made torules or regulations promulgated thereunder, nor can we predict the CCPA or how these will be interpreted.full impact of any interpretations thereof. While we believe we have developed processes and notices that are intended to comply in all material respects with applicable CCPA and CPRA requirements, a regulatory agency may not agree with certain of our

14

implementation decisions, which could subject us to litigation, regulatory actions or changes to our business practices that could increase costs or reduce revenues. Other states including Colorado, Connecticut, Delaware, Florida, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Virginia have also considered or are considering privacy laws similar to the CCPA.CCPA and the CPRA, and a federal consumer privacy law has also been proposed. Similar laws may be implemented in other jurisdictions that we do business in and in ways that may be more restrictive than the CCPA or the CPRA, increasing the cost of compliance, as well as the risk of noncompliance, on our business.

Risks Related to Conflicts

Certain of Interest

Ourour officers and certain of our key personnel will face competing demands relating to their time and this maywill face conflicts of interest related to the positions they hold with affiliated entities, which could cause our operating resultsbusiness to suffer.

Our

Certain of our officers and certain of our key personnel and their respective affiliates are officers, key personnel, advisors, managers, and sponsors of other real estate programs having investment objectives and legal and financial obligations similar to ours, including the Managed REITs. In addition, our Chief Executive Officer remains (i) Chairman of the Board of Strategic Student & Senior Housing Trust, Inc. and (ii) the Chief Executive Officer of our former sponsor. Because these persons have competing demands on their time and resources, they may have conflicts of interest in allocating their time between our business and these other activities. During times of intense activity in other programs and ventures, they may devote lessShould these persons not balance these competing demands on their time and fewer resources, to our business than is necessary or appropriate. If this occurs, the returns on our stockholders’ investments maycould suffer.

Certain of our officers 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 our stockholders.

Certain of our executive officers are also officers of affiliated entities, including the Managed REITs. As a result, Furthermore, these individualspersons owe fiduciary duties to these other entities and their owners, which fiduciary duties may conflict with the duties that they owe to our stockholders and us. Their loyalties to these other entities could result in actions or inactions that are detrimental to our business, which could harm the implementation of our investment objectives. Conflicts with our businessbusiness.

Our Chief Executive Officer has direct and interests are most likely to arise from involvement in activities related to (1) allocation of new investments and management time and services between us and the other entities, (2) our purchase of properties from, or sale of properties to, affiliated entities, (3) the timing and terms of the investment in or sale of an asset, (4) development of our properties by affiliates, and (5) investments with affiliates. If we do not successfully implement our investment objectives, we may be unable to generate cash needed to continue to pay distributions at the current rate to our stockholders and to maintain or increase the value of our assets.

We may face a conflict of interest if we purchase properties from, or sell properties to, our affiliates, including the Managed REITs.

We may purchase properties from, or sell properties to, one or more of our affiliates, including the Managed REITs, in the future. A conflict of interest may exist if such acquisition or disposition occurs. The business interests of our affiliates may be adverse to, or to the detriment of, our interests. Additionally, if we purchase properties from our affiliates, the prices we pay to these affiliates for our properties may be equal to, or in excess of, the prices paid by them, plus the costs incurred by them relating to the acquisition and financing of the properties. If we sell properties to our affiliates, the offers we receive from these affiliates for our properties may be equal to, or less than, the prices we paid for the properties. These prices will not be the subject of arm’s-length negotiations, which could mean that the acquisitions may be on terms less favorable to us than those negotiated in an arm’s-length transaction. Even though we intend to use an independent third-party appraiser to determine fair market value when acquiring properties from, or selling properties to, our affiliates, we may pay more, or may not be offered as much, for particular properties than we would have in an arm’s-length transaction, which would reduce our cash available for investment in other properties or distribution to our stockholders.

Furthermore, because any agreement that we enter into with our affiliates will not be negotiated in an arm’s-length transaction, we may be reluctant to enforce the agreements against those affiliated entities.

15

We will face conflicts of interest relating to joint ventures that we may form with our affiliates, which conflicts could result in a disproportionate benefit to other joint venture partners at our expense.

We may enter into joint ventures with our affiliates, including the Managed REITs, for the acquisition, development, or improvement of properties. We may have conflicts of interest in determining which program should enter into any particular joint venture agreement. The co-venturer may have economic or business interests or goals that are or may become inconsistent with our business interests or goals. In addition, we may face a conflict in structuring the terms of the relationship between our interests and the interest of the affiliated co-venturer and in managing the joint venture. Agreements and transactions between us and the co-venturers with respect to any such joint venture will not have the benefit of arm’s-length negotiation of the type normally conducted between unrelated co-venturers, which may result in the co-venturers receiving benefits greater than the benefits that we receive. In addition, we may assume liabilities related to the joint venture that exceeds the percentage of our investment in the joint venture, and this could reduce the returns on investment.

Such limited partnership interestsOP units may be exchanged for our common stock in the future. In addition, in certain circumstances such as a merger, sale of all or substantially all of our assets, share exchange, conversion, dissolution or amendment to our charter, in each case where the vote of our stockholders is required under Maryland law, the consent of our Operating Partnership will also be required, which could result in our Chief Executive ChairmanOfficer being able to influence such matters submitted to a vote of our stockholders. This may result in an outcome that may not be favorable to our stockholders. Our Chief Executive ChairmanOfficer may also make decisions on behalf of SAM related to redemptions of either its limited partnership interestsOP units or its common stock which may negatively impact our stockholders.

Revenue and earnings from the Managed REIT Platform are uncertain.

Increasing our revenue from the Managed REIT Platform is no separate counseldependent in large part on the ability to raise capital in offerings for usexisting or future Managed REITs or other future programs, as well as on our ability to make investments that meet the investment criteria of existing and future entities, both of which are subject to uncertainty with respect to capital market and real estate market conditions. This uncertainty could have an adverse impact on our earnings. Moreover, revenue generated from asset management fees, property management fees, and other fees and distributions relating to the Managed REITs’ offerings and the investment and management of their respective assets may be affected by factors that include not only our ability to increase the Managed REITs’ portfolio of properties under management, but also changes in valuation of those properties, sales of the Managed REIT properties and assets and our affiliates,ability to successfully operate the Managed REIT properties.

The Managed REITs may not generate sufficient revenue or may incur significant debt, which either due to liquidity problems or restrictive covenants contained in their borrowing agreements could result in conflicts of interest.

Nelson Mullins Riley & Scarborough LLP (Nelson Mullins) acts as legal counselrestrict their ability to pay or reimburse fees and expenses owed to us and also represents somewhen due. In addition, the revenue payable by the Managed REITs is subject to certain limits set forth in their respective advisory agreements, which may limit the growth of our affiliates, includingrevenue. Furthermore, our ability to earn certain subordinated distributions from the Managed REITs is tied to providing liquidity events for the Managed REITs. There isOur

ability to provide such liquidity events, and to do so under circumstances that will satisfy the applicable subordination requirements, will depend on market conditions at the relevant time, which may vary considerably over a possibilityperiod of years. If we are unable to satisfy such subordination requirements, certain equity interests we hold in the futureManaged REITs may be impaired.

Because the revenue streams from the advisory agreements with the Managed REITs are subject to limitation or cancellation, any such termination could adversely affect our financial condition, cash flow and the amount available for distributions to our common stockholders.

Our advisory agreements with the Managed REITs are subject to the renewal terms thereof and each may generally be terminated by each Managed REIT, without cause or penalty, upon 60 days’ written notice. There can be no assurance that the interestsadvisory agreements will be renewed before they expire or that the advisory agreements will not be terminated. Any such non-renewal or termination could adversely affect our financial condition, cash flow and the amount available for distributions to our common stockholders.

We will face conflicts of interest relating to the purchase of properties, including conflicts with the Managed REITs, and there can be no assurance that our investment allocation policy will adequately address all of the various partiesconflicts that may become adversearise or that it will address such conflicts in a manner that is more favorable to us than to the Managed REITs.

We own the entities that serve as the sponsor and underadvisor to the code of professional responsibility of the legal profession, Nelson MullinsManaged REITs, which have investment objectives similar to ours, and we may be precluded from representing any one or all of such parties. If any situation arises in which our interests appear to be in conflict with those of our affiliates, additional counsel may be retained bybuying properties at the same time as one or more of the parties to assure that their interests are adequately protected. Moreover, should a conflictManaged REITs, or other programs managed by us, our officers, our key personnel or our subsidiaries (the “Other Programs”). Accordingly, we will have conflicts of interest in allocating potential properties, acquisition expenses, management time, services, and other functions between various existing enterprises or future enterprises with which the Managed REITs may be or become involved. SST VI is a public non-traded Managed REIT which began operations in early 2021 that invests in self storage properties and has assets of approximately $560 million as of December 31, 2023, and SSGT III is a private Managed REIT which began operations in May 2022 that invests in self storage properties and had assets of approximately $180 million as of December 31, 2023.

While we have adopted an acquisition allocation policy in an effort to appropriately allocate acquisitions among us, the Managed REITs and the Other Programs, there can be no assurance that such allocation policy will adequately address all of the conflicts that may arise or that it will address such conflicts in a manner that is more favorable to us than to the Managed REITs or the Other Programs. In addition, conflicts of interest may exist in the valuation of our investments and regarding decisions about the allocation of specific investment opportunities among us, the Managed REITs and the Other Programs and the allocation of fees and costs among us, the Managed REITs and the Other Programs. To the extent we fail to appropriately deal with any such conflicts, it could negatively impact our reputation and ability to raise additional funds or result in potential litigation against us.

If the Managed REITs are unable to repay certain loans made to them by us or redeem certain preferred equity investments made in them by us, our liquidity, financial condition, cash flow, and the amount available for distributions to our common stockholders could be adversely affected.

We have provided and may continue to provide financial support to the Managed REITs in the form of mezzanine loans, preferred equity investments, and other strategic investments. As of March 13, 2024, we had an aggregate of approximately $17.0 million in outstanding loans to the Managed REITs. Additionally, we had previously invested an aggregate of approximately $15.0 million in the form of preferred units of the Managed REITs’ operating partnerships, which were redeemed. If the Managed REITs are unable to raise sufficient additional capital or produce adequate funds from operations, they may not be readily apparent, Nelson Mullinsable to repay such loan amounts. As a result, the amounts loaned or invested may inadvertently act in derogation of the interest of the parties,remain unavailable to us longer than expected, which could affecthave a negative impact on our liquidity and could result in us pursuing additional capital in the form of additional debt or equity issuances. If we are unable to acquire additional capital, our financial condition, cash flow, and the amount available for distributions to our common stockholders could be adversely affected.

We are obligated under the Sponsor Funding Agreement to fund up to $70 million for the upfront sales load in the SST VI public offering, which may limit our ability to meetmake investments and/or fund distributions to our investment objectives.stockholders or use for other working capital purposes, and there is no guarantee that we will receive a return on this investment.

On November 1, 2023, we (through our indirect subsidiary, SmartStop REIT Advisors, LLC, or “SRA”) entered into a Sponsor Funding Agreement with SST VI and its operating partnership and we 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 (the “Class Y Shares”) sold in the SST VI public offering, (ii) the upfront 3% dealer manager fee for the Class Y Shares sold in the SST VI public 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 (the “Class Z Shares”) sold in the SST VI public offering. SRA also reimbursed 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 public offering, which reimbursement was approximately $6.6 million. Additionally, 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.

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, the SST VI operating partnership will issue a number of Series C Subordinated Convertible Units of limited partnership interest in the SST VI operating partnership (the “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 public offering, which will initially be $9.30 per share. The Series C Units are subordinated such that SRA is not entitled to distribution, liquidation, voting or other rights to participate in SST VI’s operating partnership, unless and until such units are converted into class A units of their operating partnership. 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.

We are obligated to fund up to $70 million pursuant to the Sponsor Funding Agreement, which may limit our ability to make other investments and/or fund distributions to our stockholders or use for other working capital purposes. In addition, there is no guarantee that the Series C Units will convert into class A units or that we will receive a return on this investment.

A subsidiary of ours is the sponsor of the Managed REITs and may sponsor additional future programs. As a result, we could be subject to any litigation that may arise by investors in those entities or the respective operations of those entities.

In the course of their operations, the Managed REITs and the other future programs may be subject to lawsuits. We may be named in such lawsuits as the sponsor of such entities and may, in some instances, be found to be subject to liability. In such an instance, our ability to seek reimbursement or indemnification from such programs may be limited. If we are subject to significant legal expenses, it could have an adverse effect on our financial condition.

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.

In order for us to qualify as a REIT, no more than 50% of our outstanding stock may be beneficially owned, directly or indirectly, by five or fewer individuals (including certain types of entities) at any time during the last half of each taxable year. To ensure that we do not fail to qualify as a REIT under this test, our charter restricts ownership by one person or entity to no more than 9.8% of the value of our then-outstanding capital stock or more than 9.8% of the value or number of shares, whichever is more restrictive, of our then outstanding common stock. This restriction may have the effect of delaying, deferring, or preventing a change in control of us, including an extraordinary transaction (such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price for holders of our common stock.

16

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.

Our charter permits our board of directors to issue up to 900,000,000 shares of capital stock. In addition, our board of directors, without any action by our stockholders, may amend our charter from time to time to increase or decrease the aggregate number of shares or the number of shares of any class or series of stock that we have authority to issue. Our board of directors may classify or reclassify any unissued common stock or preferred stock and establish the preferences, conversion or other rights, voting powers, restrictions, limitations as to distributions, qualifications and terms or conditions of redemption of any such stock. Thus, our board of directors could authorize the issuance of preferred stock with terms and conditions that have a priority as to distributions and amounts payable upon liquidation over the rights of the holders of our common stock, such as our Series A Convertible Preferred Stock. See the risk factor captioned “We have issued Series A

Convertible Preferred Stock that ranks senior to all common stock and grants the holder superior rights compared to common stockholders, which may have the effect of diluting our stockholders’ interests in us and discouraging a takeover or other similar transaction.” in the section titled “Risks Related to an Investment in SmartStop Self Storage REIT, Inc.,” above. Preferred stock could also have the effect of delaying, deferring, or preventing a change in control of our company, including an extraordinary transaction (such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price for holders of our common stock.

We will not be affordedhave opted out of provisions of the protection of Maryland lawMGCL relating to business combinations.deterring or defending hostile takeovers.

Under Maryland law, “business combinations” between a Maryland corporation and an interested stockholder (as defined in the statute) or an affiliate of an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, share exchange, or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. An interested stockholder is defined as:

These prohibitions are intended to prevent a change of control by interested stockholders who do not have the support of our board of directors. Pursuant to the statute, our board of directors has by resolution exempted business combinations between us and any person, provided that the business combination is first approved by our board of directors. We cannot assure you that

Also, under Maryland law, control shares of a Maryland corporation acquired in a control share acquisition have no voting rights except to the extent approved by a vote of stockholders entitled to cast two-thirds of the votes entitled to be cast on the matter. Shares owned by the acquirer, an officer of the corporation, or an employee of the corporation who is also a director of the corporation, are excluded from the vote on whether to accord voting rights to the control shares. As permitted by the MGCL, our boardbylaws contain a provision exempting from the control share acquisition statute any and all acquisitions by any person of directors will not amend or repeal this resolution inour stock.

Our decision to opt out of the future. Therefore, we will not be affordedabove provisions of the MGCL removes certain protections of this statute and, accordingly, therethe MGCL that may otherwise deter a hostile takeover or assist us in defending against a hostile takeover. There is no guarantee that the ownership limitations in our charter would provide the same measure of protection as the business combinations statuteabove provisions of the MGCL and prevent an undesired change of control by an interested stockholder.

Our rights and the rights of our stockholders to recover claims against our officers and directors are limited, which could reduce our stockholders’ and our recovery against them if they cause us to incur losses.

Maryland law provides that a director has no liability in that capacity if the director performs theirhis or her duties in good faith, in a manner the director reasonably believes to be in the corporation’s best interests, and with the care that an ordinarily prudent person in a like position would use under similar circumstances. Our charter requires us to indemnify our directors and officers and permits us to indemnify our employees and agents for actions taken by them in good faith and without negligence or misconduct.to the maximum extent permitted under Maryland law. Additionally, our charter limits the liability of our directors and officers for monetary damages to the maximum extent permitted under Maryland law. As a result, we and our stockholders may have more limited rights against our directors, officers, employees and agents than might otherwise exist under common law, which could reduce our stockholders’ and our recovery against them. We have also entered into indemnification agreements with each of our directors and executive officers, which obligate us to indemnify such persons in certain circumstances, including if they are or are threatened to be made a party to, or witness in, any proceeding by reason of their status as a present or former director or officer of us. In addition, we may be obligated to fund the defense costs incurred by our directors, officers, employees and agents in some cases which would decrease the cash otherwise available for distribution to our stockholders.

17

Our board of directors may change any of our investment objectives, including our focus on self storage facilities.

Our board

Future offerings of directorsdebt securities, which would be senior to our common stock, or equity securities, which would dilute our existing stockholders and may change any ofbe senior to our investment objectives, including our focus on self storage facilities. Ifcommon stock, may adversely affect our stockholders, do not agree with a decision ofand our board to change any of our investment objectives, our stockholders only have limited control over such changes. Additionally, we cannot assure our stockholders that we would be successful in attaining any of these investment objectives, which may adversely impact our financial performance and ability to make distributions to our stockholders.

Our stockholders’ interests in us will be diluted as we issue additional shares.

Our stockholders will not have preemptive rights to any shares issued by us

We may in the future. Subjectfuture attempt to increase our capital resources by offering debt or equity securities, including notes and classes of preferred or common stock. Debt securities or shares of preferred stock may generally be entitled to receive interest payments or distributions, both current and in connection with any liquidation or sale, prior to the holders of our common stock. We are not required to offer any such additional debt or equity securities to existing common stockholders on a preemptive basis. Therefore, offerings of common stock or other equity securities may dilute the holdings of our existing stockholders. Because we may generally issue any such debt or equity securities in the future without obtaining the consent of our stockholders, you will bear the risk of such future offerings, including the dilution of your proportionate ownership.

In addition, subject to any limitations set forth under Maryland law, our board of directors may increase the number of authorized shares of stock (currently 900,000,000 shares), increase or decrease the number of shares of any class or series of stock designated, or reclassify any unissued shares without the necessity of obtaining stockholder approval. All such shares may be issued in the discretion of our board of directors. Further, our Series A Convertible Preferred Stock may be converted into our common stock under certain circumstances. In addition, we have granted, and expect to grant in the future, equity awards to our independent directors and certain of our employees, including our executive officers, which to date consist of restricted stock of the Company and LTIP units of our Operating Partnership, which are convertible into shares of our common stock subject to satisfaction of certain conditions. Finally, a subsidiary of SAM owns units of limited partnership interest in our Operating Partnership which are convertible into shares of our Class A common stock under certain circumstances.

Therefore, existing stockholders will experience dilution of their equity investment in us as we (1) sell additional shares in the future, including those issued pursuant to our distribution reinvestment plan, (2) sell securities that are convertible into shares of our common stock, (3) issue shares of our common stock in a private offering of securities, (4) issue restricted shares of our common stock or other equity-based securities to our independent directors and executive officers, (5) issue shares of our common stock in a merger or to sellers of properties acquired by us in connection with an exchange of limited partnership interests of our Operating Partnership, or (6) convert shares of our Series A Convertible Preferred Stock into shares of our common stock.

Because the limited partnership interests of our Operating Partnership may, in the discretion of our board of directors, be exchanged for shares of our common stock, any merger, exchange or conversion between our Operating Partnership and another entity ultimately could result in the issuance of a substantial number of shares of our common stock, thereby diluting the percentage ownership interest of other stockholders. Because of these and other reasons, our stockholders may experience substantial dilution in their percentage ownership of our shares.

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.

We expect our primary use of capital to be paying distributions to our stockholders and making capital investments into our assets and our business.  In addition, in order to continue to qualify as a REIT, we generally must distribute to our stockholders at least 90% of our taxable income each year, excluding capital gains. Because of this distribution requirement, it is not likely that we will be able to fund a significant portion of our future capital needs from retained earnings. We have limited any additional sources of capital for future funding, and such sources of funding may not be available to us on favorable terms or at all. If we do not have access to sufficient funding in the future, we may not be able to make necessary capital improvements to our properties, pay other expenses or expand our business.

Risks Related to the Self Storage Industry

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.

Because our portfolio of properties consists primarily of self storage facilities, we are subject to risks inherent in investments in a single industry. A decrease in the demand for self storage space would likely have a greater adverse effect on our rental revenues than if we owned a more diversified real estate portfolio. Demand for self storage space has been and could be adversely affected by weakness in the national, regional, and local economies and changes in supply of or demand for similar or competing self storage facilities in an area. To the extent that any of these conditions occur, they are likely to affect demand, and market rents, for self storage space, which could cause a decrease in our rental revenue. Any such decrease could impairhave a material adverse impact on our ability to continue to pay distributions at the current rate to our stockholders.business, financial condition, and results of operations. We do not expect to invest in other real estate or businesses to hedge against the risk that industry trends might decrease the profitability of our self storage-related investments.

18

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.

We face intense competition in every market in which we purchase self storage facilities. We compete with numerous national, regional, and local developers, owners and operators in the self storage industry, including the Managed REITs, publicly traded REITs, other REITs and other REITs.institutional investment funds. Moreover, development of self-storageself storage facilities has increased in recent years, which has intensified competition, and we expect it will continue to do so as newly developed facilities are opened. In addition, competition for suitable investments may reduce the number of suitable investment opportunities available to us, may increase acquisition costs, and may reduce demand for self storage units in certain areas

where our facilities are located, all of which may adversely affect our operating results. Additionally, an economic slowdown in a particular market could have a negative effect on our self storage revenues.

If competitors build new facilities that compete with our facilities or offer space at rental rates below the rental rates we charge our customers, we may lose potential or existing customers and we may be pressured to discount our rental rates to retain customers. As a result, our rental revenues may become insufficient to continue to pay distributions at the current rate to our stockholders. In addition, increased competition for customers may require us to make capital improvements to facilities that we would not otherwise make,make. As a result, our rental income could decline, which could reduce cash availablehave a material adverse impact on our business, financial condition, and results of operations.

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 expect to make future acquisitions of self storage properties. We may not be successful in identifying and consummating suitable acquisitions that meet our criteria, which may impede our growth. We may encounter competition when we seek to acquire properties, especially for distributionbrokered portfolios. Aggressive bidding practices by prospective acquirers have been commonplace and this competition also may be a challenge for our acquisition strategy and potentially result in our paying higher prices for acquisitions, including, in some instances, paying consideration for certain properties that may be more than others are willing to pay for such properties. Should we pay higher prices for self storage properties or other assets, our stockholders.operating results may suffer. Furthermore, when we acquire self storage properties, we will be required to integrate them into our then-existing portfolio. The acquired properties may turn out to be less compatible with our acquisition strategy than originally anticipated, may cause disruptions in our operations, or may divert management’s attention away from day-to-day operations, which could impair our results of operations. Our ability to acquire or integrate properties may also be constrained by the following additional risks:

The acquisition of new properties may give rise to difficulties in predicting revenue potential.

New acquisitions could fail to perform in accordance with our expectations. If we fail to accurately estimate occupancy levels, rental rates, operating costs, or costs of improvements to bring an acquired facility up to our standards, the performance of the facility may be below expectations. Properties we acquire may have characteristics or deficiencies affecting their valuation or revenue potential that we have not yet discovered. We cannot assure our stockholders that the performance of properties we acquire will increase or be maintained under our management.

We may be unable to promptly re-let units within our facilities at satisfactory rental rates.

Generally, our unit leases are on a month-to-month basis. Delays in re-letting units as vacancies arise would reduce our revenues and could adversely affect our operating performance. In addition, lower-than-expected rental rates and higher rental concessions upon re-letting could adversely affect our rental revenues and impede our growth.

We depend on our on-site personnel to maximize customer satisfaction at each of our facilities, and any difficulties we encounter in hiring, training, and retaining skilled field personnel may adversely affect our rental revenues.

The customer service, marketing skills, knowledge of local market demand and competitive dynamics of our facility managers are contributing factors to our ability to maximize our rental income and to achieve the highest sustainable rent levels at each of our facilities. If we are unable to successfully recruit, train, and retain qualified field personnel, our rental revenuesincomes may be adversely affected, which could impairhave a material adverse impact on our ability to continue to pay distributions at the current rate to our stockholders.

Legal claims related to moisture infiltrationbusiness, financial condition, and mold could arise in one or moreresults of our properties, which could adversely affect our revenues.operations.

Delays in development and lease-up of our properties would reduce our profitability.

We may acquire properties that require repositioning or redeveloping such properties with the goal of increasing cash flow, value or both. Construction delays to new or existing self storage properties due to weather, unforeseen site conditions, personnel problems, (including as a result of the COVID-19 outbreak), and other factors could delay our anticipated customer occupancy plan which could adversely affect our profitability and cash flow. Furthermore, our estimate of the costs of repositioning or redeveloping an acquired property may prove to be inaccurate, which may result in our failure to meet our profitability goals. We have encountered in the past, and we may also encounter in the future unforeseen cost increases associated with building materials or construction services resulting from trade tensions, disruptions, tariffs, duties or restrictions or an epidemic, pandemic or other health crisis, such as the COVID-19 outbreak. Additionally, we may acquire a new property that has a relatively low physical occupancy, and the cash flow from existing operations may be insufficient to pay the operating expenses associated with that property until the property is adequately leased. If one or more of these properties do not perform as expected or we are unable to successfully integrate new properties into our existing operations, our financial performance and our ability to make distributions may be adversely affectedaffected..

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 and returns to our stockholders.operations.

The self storage facilities we own and operate are leased directly to customers who store their belongings without any immediate inspections or oversight from us. We may unintentionally lease space to groups engaged in illegal and dangerous activities. Damage to storage contents may occur due to, among other occurrences, the following: war, acts of terrorism, earthquakes, floods, hurricanes, pollution, environmental matters, fires or events caused by fault of a customer, fault of a third party, or fault of our own. Such damage may or may not be covered by insurance maintained by us, if any. We will determine the amounts and types of insurance coverage that we will maintain, including any coverage over the contents of any properties in which we may invest. Such determinations will be made on a case-by-case basis based on the type, value, location, and risks associated with each investment, as well as any lender requirements, among any other factors we may consider relevant. There is no guarantee as to the type of insurance that we will obtain for any investments that we may make and there is no guarantee that any particular damage to storage contents would be covered by such insurance, even if obtained. The costs associated with maintaining such insurance, as well as any liability imposed upon us due to damage to storage contents, may have ana material adverse effectimpact on our business, financial condition, and results of operations and returns to our stockholders.operations.

Additionally, although we require our customers to sign an agreement stating that they will not store flammable, hazardous, illegal, or dangerous contents in the self storage units, we cannot ensure that our customers will abide by such agreement.agreement or otherwise comply with applicable laws, including environmental, health and safety laws. The storage of such materials or violation of applicable laws might cause destruction to a facility or impose liability on us for the costs of removal or remediation if these various contents or substances are released on, from or in a facility, which may have ana material adverse effectimpact on our business, financial condition, and results of operations and returns to our stockholders.operations.

Our operating results may be affected by regulatory changes that have an adverse impact on our specific facilities, including our ability to obtain required permits and approvals, which may adversely affect our business, financial condition, and results of operations and returns to our stockholders.operations.

Certain regulatory changes may have a direct impact on our self storage facilities, including but not limited to, land use, zoning, and permitting requirements by governmental authorities at the local level, which can restrict the availability of land for development, and special zoning codes which omit certain uses of property from a zoning category. These special uses (i.e., hospitals, schools, and self storage facilities) are allowed in that particular zoning classification only by obtaining a special use permit and the permission of local zoning authority. If we are delayed in obtaining or unable to obtain a special use permit where one is required, new developments or expansion of existing developments could be delayed or reduced. Additionally, certain municipalities require holders of a special use permit to have higher levels of liability coverage than is normally required. The acquisition of, or the inability to obtain, a special use permit and the possibility of higher levels of insurance coverage associated therewith may have an adverse effectimpact on our business, financial condition, and results of operations and returnsoperations.

In certain cases, we protect our customers’ goods pursuant to our stockholders.tenant protection program or other arrangements that may, in some cases, be subject to governmental regulation, which may adversely affect our results.

In certain cases, we provide a tenant protection program to customers at our properties, and in certain other cases, we protect our customers goods through other arrangements. We earn fees in connection with these arrangements. These

arrangements, including the payments associated with these arrangements, may be subject to state-specific or provincial-specific governmental regulation. Such regulatory authorities generally have broad discretion to promulgate, interpret and implement regulations, to adopt new or additional licensing requirements, to grant, renew and revoke licenses and approvals, and to evaluate compliance with regulations through periodic examinations, audits, investigations and inquiries. In addition, there has been and may continue to be regulatory or private action in the jurisdictions in which we operate. Although the marketing of, and management procedures associated with, these arrangements were designed to navigate the regulatory environment in which we operate, as a result of regulatory or private action in any jurisdiction in which we operate, we may be temporarily or permanently suspended from generating revenue with respect to these arrangements, or otherwise fined or penalized or suffer an adverse judgment, which could adversely affect our business and results of operations.

A failure in, or breach of, our operational or security systems or infrastructure, or those of our third party vendors and other service providers or other third parties, including as a result of cyber attacks, could disrupt our businesses, result in the disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs, and cause losses.

We rely heavily on communications and information systems to conduct our business. Information security risks for our business have generally increased in recent years in part because of the proliferation of new technologies; the use of the

20

Internet and telecommunications technologies to process, transmit and store electronic information, including the management and support of a variety of business processes, including financial transactions and records, personally identifiable information, and tenant and lease data; and the increased sophistication and activities of organized crime, hackers, and terrorists, activists, and other external parties. As customer, public, and regulatory expectations regarding operational and information security have increased, our operating systems and infrastructure must continue to be safeguarded and monitored for potential failures, disruptions, and breakdowns. Our business, financial, accounting, and data processing systems, or other operating systems and facilities, may stop operating properly or become disabled or damaged as a result of a number of factors, including events that are wholly or partially beyond our control. For example, there could be electrical or telecommunication outages; natural disasters such as earthquakes, tornadoes, and hurricanes; disease pandemics; events arising from local or larger scale political or social matters, including terrorist acts; and as described below, cyber attacks.

Our business relies on its digital technologies, computer and email systems, software and networks to conduct its operations. Although we have information security procedures and controls in place, our technologies, systems and networks and, because the nature of our business involves the receipt and retention of personal information about our customers, our customers’ personal accounts may become the target of cyber attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss, or destruction of our or our customers’ or other third parties’ confidential information. Third parties with whom we do business or who facilitate our business activities, including intermediaries or vendors that provide service or security solutions for our operations, and other third parties, could also be sources of operational and information security risk to us, including from breakdowns or failures of their own systems or capacity constraints. In addition, hardware, software or applications we develop or procure from third parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security.

While we have disaster recovery and other policies and procedures designed to prevent or limit the effect of the failure, interruption or security breach of our information systems, there can be no assurance that any such failures, interruptions or security breaches will not occur or, if they do occur, that they will be adequately addressed. Our risk and exposure to these matters remain heightened because of the evolving nature of these threats. As a result, cyber security and the continued development and enhancement of our controls, processes, and practices designed to protect our systems, computers, software, data, and networks from attack, damage or unauthorized access remain a focus for us. As threats continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate information security vulnerabilities. Disruptions or failures in the physical infrastructure or operating systems that support our businesses and customers, or cyber attacks or security breaches of the networks, systems or devices that our customers use to access our products and services, could result in customer attrition, regulatory fines, penalties or intervention, reputation damage, reimbursement or other compensation costs, and/or additional compliance costs, any of which could have a material effect on our business, financial condition, or results of operations or financial condition.from operations. Furthermore, if such attacks are not detected immediately, their effect could be compounded.

If we enter into non-compete agreements with the sellers of the self storage properties that we acquire,

We may be unable to promptly re-let units within our facilities at satisfactory rental rates.

Generally, our unit leases are on a month-to-month basis. Delays in re-letting units as vacancies arise would reduce our revenues and the terms of those agreements expire, the sellers may compete with us within the general location of one of our self storage facilities, which could have an adverse effect onadversely affect our operating resultsperformance. In addition, lower-than-expected rental rates and returns tohigher rental concessions upon re-letting could adversely affect our stockholders.rental revenues and impede our growth.

We may enter into non-compete agreements with the sellers of the self storage properties that we acquire in order to prohibit the seller from owning, operating, or being employed by a competing self storage property for a predetermined time frame and within a geographic radius of a self storage facility we acquire. When these non-compete agreements expire, we may face the risk that the seller will develop, own, operate, or become employed by a competing self storage facility within the general location of one of our properties, which could have an adverse effect on our operating results and returns to our stockholders.

We face risks related to an epidemic, pandemic or other health crisis, such as the recent outbreak of the novel coronavirus (“COVID-19”), which could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects.

We face risks related to an epidemic, pandemic or other health crisis, including the ongoing COVID-19 pandemic which impacts the United States, Canada and the markets in which we operate and could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects. Our rental revenue and operating results depend significantly on the demand for self storage space. While we have not seen a continuing material impact on the demand for self storage space resulting from the COVID-19 pandemic as of the date of this report, if the pandemicIf such an event causes weakness in national, regional and local economies that negatively impact the demand for self storage space and/or increase

Additionally, we typically conduct aspects of our leasing activity at our facilities, as well as the offering of various ancillary products, including moving and packing supplies, such as locks and boxes, and other services, such as protection plans, tenant insurance or similar programs. Accordingly,Further, if such an event results in reductions in the ability and willingness of customers to visit our facilities, due to the COVID-19 pandemicwe could reduceexperience reduced rental revenue and ancillary operating revenue produced by our facilities. Concerns relating toand changes in behavior as a result of such a pandemican event could also impact the availability of oursite-level personnel, to report for work at our facilities, which could adversely affect our ability to adequately manage our facilities. In order to prevent the spread of COVID-19 there have been, and may continue to be, temporary shut downs or restrictions placed on businesses by cities, counties, states, or the federal government. These orders have impacted, and may continue to impact, our facilities and 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 our stockholders that we will be profitable or that we will realize growth in the value of our real estate properties.

Our operating results will be subject to risks generally incident to the ownership of real estate, including:

These and other reasons may prevent us from being profitable or from realizing growth or maintaining the value of our real estate properties.

We may suffer reduced or delayed revenues for, or have difficulty selling, properties with vacancies.

We anticipate that the majority of the properties we own or will acquire will ultimately have stabilized occupancy levels (at or above 75%). However, certain of the real properties we own or will acquire may have some level of vacancy at the time of closing either because the property is in the process of being developed and constructed, it is newly constructed and in the process of obtaining customers, or because of economic or competitive or other factors. Shortly after a new property is opened, during a time of development and construction, or because of economic or competitive or other factors, we may suffer reduced revenues resulting in lower cash distributions to our stockholders due to a lack of an optimum level of customers. The resale value of properties with prolonged low occupancy rates could suffer, which could further reduce our stockholders’ returns.

A high concentration of our properties in a particular geographic area would magnify the effects of downturns in that geographic area.

In the event that we have a concentration of properties in any particular geographic area, any adverse situation that disproportionately affects that geographic area would have a magnified adverse effect on our portfolio. For the month of December 2020,2023, approximately 24%23%, 21%20%, and 13%10% of our rental income was concentrated in Florida, California, Florida, and Ontario (Canada),the Greater Toronto Area of Canada, respectively. Moreover, if the SST IV Merger had been effected prior to the month of December 2020, approximately 21%, 22%, and 11% of the combined company’s rental income for the month of December 2020 would have been concentrated in California, Florida, and Ontario (Canada), respectively.

22

We may obtain only limited warranties when we purchase a property.

The seller of a property will often sell such property in its “as is” condition on a “where is” basis and “with all faults,” without any warranties of merchantability or fitness for a particular use or purpose. In addition, purchase agreements may contain only limited warranties, representations, and indemnifications that will only survive for a limited period after the closing. Also, many sellers of real estate are single purpose entities without significant other assets. The purchase of properties with limited warranties or from undercapitalized sellers increases the risk that we may lose some or all of our invested capital in the property as well as rental income from that property.

We may acquire or finance properties with yield maintenance or defeasance provisions, which may restrict our operational and financial flexibility.

Yield maintenance or defeasance provisions are provisions that generally require the payment of a premium in connection with the prepayment of a loan balance. Such provisions are typically provided for by the terms of the agreement underlying a loan. Yield maintenance or defeasance provisions could materially restrict us from selling or otherwise disposing of or refinancing properties. These provisions would affect our ability to turn our investments into cash and thus affect cash available for distribution to our stockholders. Yield maintenance or defeasance provisions may increase the costs of reducing the outstanding indebtedness with respect to any properties or refinancing such indebtedness.

Yield maintenance or defeasance provisions could impair our ability to take actions that would otherwise be in our stockholders’ best interests and, therefore, may have an adverse impact on the value of the shares, relative to the value that would result if such provisions did not exist. In particular, yield maintenance or defeasance provisions could preclude us from participating in major transactions that could result in a disposition of our assets or a change in control, even though that disposition or change in control might be in our stockholders’ best interests.

Rising expenses could reduce cash available for future acquisitions.

Any properties that we buy in the future will be subject to operating risks common to real estate in general, any or all of which may negatively affect us. If any property is not fully occupied or if rents are being paid in an amount that is

insufficient to cover operating expenses, we could be required to expend funds for that property’s operating expenses. Our properties will be subject to increases in tax rates, utility costs, operating expenses, insurance costs, repairs and maintenance and administrative expenses.

If we are unable to offset such cost increases through rent increases, we could be required to fund those increases in operating costs which could adversely affect funds available for future acquisitions or cash available for distribution.

Our real estate assets may decline in value and be subject to significant impairment losses, which may reduce our net income.

We evaluate our real property assets for impairment based on events and changes in circumstances that may impact the carrying amounts of such assets. When indicators of potential impairment are present, we will assess the recoverability of the particular asset by determining whether the carrying value of the asset will be recovered, through an evaluation of the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. This evaluation is based on a number of estimates and assumptions. These key assumptions are subjective in nature and may differ materially from actual results. Based on this evaluation, if the expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the real property asset and recognize an impairment loss. Additionally, changes in our disposition strategy or changes in the marketplace may alter the holding period of an asset or asset group, which may result in an impairment loss, and such loss may be material to our financial condition or operating performance.

The fair value of real estate assets is subjective and is determined through the use of comparable sales information and other market data if available. These subjective assessments have a direct effect on our net income because recording an impairment loss results in an immediate negative adjustment to net income, which may be material.

Adverse economic conditions will negatively affect our returns and profitability.

The following market and economic challenges may adversely affect our operating results:

We are susceptible to the effects of adverse macro-economic events that can result in higher unemployment, shrinking demand for products, large-scale business failures, and tight credit markets, such as inflation, rising interest rates, or labor shortages. Because our portfolio of facilities consists of self storage facilities, we are subject to risks inherent in investments in a single industry, and our results of operations are sensitive to changes in overall economic conditions that impact consumer spending, including discretionary spending, as well as to increased bad debts. A continuation of, or slow recovery from, ongoing adverse economic conditions affecting disposable consumer income, such as employment levels, business conditions, interest rates, tax rates, and fuel and energy costs, could reduce consumer spending or cause consumers to shift their spending to other products and services. A general reduction in the level of discretionary spending or shifts in consumer discretionary spending could adversely affect our growth and profitability.

If market conditions worsen, the value of the properties we acquire may decline. Further, the results of operations for a property in any one period may not be indicative of results in future periods, and the long-term performance of such property generally may not be comparable to, and cash flows may not be as predictable as, other properties owned by third parties in the same or similar industry.

Our inability to sell a property when we desire to do so could adversely impact our abilitybusiness and financial condition, and our inability to pay cash distributionssell our properties at a price equal to, or greater than, the price for which we purchased such properties may lead to a decrease in the value of our stockholders.assets.

The real estate market is affected by many factors, such as general economic conditions, availability of financing, interest rates and other factors, including supply and demand, that are beyond our control. Our self storage facilities, including related tangible and intangible assets, represent the majority of our total consolidated assets and they may not be readily convertible to cash. As a result, our ability to sell one or more of our self storage facilities in response to changes in economic, industry, or other conditions, may be limited. We cannot predict whether we will be able to sell any property for the price or on the terms set by us, or whether any price or other terms offered by a prospective purchaser would be acceptable to us. We cannot predict the length of time needed to find a willing purchaser and to close the sale of a property. Real estate generally cannot be sold quickly. Also, the tax laws applicable to REITs require that we hold our facilities for investment, rather than for sale in the ordinary course of business, which may cause us to forego or defer sales of facilities that otherwise would be in our best interest. Therefore, we may not be able to dispose of facilities promptly, or on favorable terms, in response to economic or other market conditions, and this may adversely impact our ability to continue to pay distributions at the current rate to our stockholders.business and financial condition.

In addition, we may be required to expend funds to correct defects or to make improvements before a property can be sold. We cannot assure our stockholders that we will have funds available to correct such defects or to make such improvements.

In acquiring a property, we may agree to restrictions that prohibit the sale of that property for a period of time or impose other restrictions, such as a limitation on the amount of debt that can be placed or repaid on that property. These provisions would also restrict our ability to sell a property.

We Additionally, 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 be purchasingacquire our properties at a time when capitalization rates are at historically low levels and purchase prices are high. Therefore, the value of our properties may not increase over time, which may restrict our ability to sell our properties, or in the event we are able to sell such property, may lead to a sale price less than the price that we paid to purchase the properties.

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.

Lock-out provisions are provisions that generally prohibit repayment of a loan balance for a certain number of years following the origination date of a loan. Such provisions are typically provided for by the Code or the terms of the agreement underlying a loan. Lock-out provisions could materially restrict us from selling or otherwise disposing of or refinancing properties. These provisions would affect our ability to turn our investments into cash and thus affect cash available for distribution to our stockholders. Lock-out provisions may prohibit us from reducing the outstanding indebtedness with respect to any properties, refinancing such indebtedness on a non-recourse basis at maturity, or increasing the amount of indebtedness with respect to such properties.

Lock-out provisions could impair our ability to take actions during the lock-out period that would otherwise be in our stockholders’ best interests and, therefore, may have an adverse impact on the value of the shares, relative to the value that would result if the lock-out provisions did not exist. In particular, lock-out provisions could preclude us from participating in major transactions that could result in a disposition of our assets or a change in control, even though that disposition or change in control might be in our stockholders’ best interests.

Rising expenses could reduce cash available for future acquisitions.

Any properties that we buy in the future will be subject to operating risks common to real estate in general, any or all of which may negatively affect us. If any property is not fully occupied or if rents are being paid in an amount that is

23

insufficient to cover operating expenses, we could be required to expend funds for that property’s operating expenses. Our properties will be subject to increases in tax rates, utility costs, operating expenses, insurance costs, repairs and maintenance and administrative expenses.

If we are unable to offset such cost increases through rent increases, we could be required to fund those increases in operating costs which could adversely affect funds available for future acquisitions or cash available for distribution.

Adverse economic conditions will negatively affect our returns and profitability.

The following market and economic challenges may adversely affect our operating results:

We are susceptible to the effects of adverse macro-economic events that can result in higher unemployment, shrinking demand for products, large-scale business failures, and tight credit markets. Because our portfolio of facilities consists of self storage facilities, we are subject to risks inherent in investments in a single industry, and our results of operations are sensitive to changes in overall economic conditions that impact consumer spending, including discretionary spending, as well as to increased bad debts due to recessionary pressures. A continuation of, or slow recovery from, ongoing adverse economic conditions affecting disposable consumer income, such as employment levels, business conditions, interest rates, tax rates, and fuel and energy costs, could reduce consumer spending or cause consumers to shift their spending to other products and services. A general reduction in the level of discretionary spending or shifts in consumer discretionary spending could adversely affect our growth and profitability.

Since we cannot predict when real estate markets may recover, the value of the properties we acquire may decline if market conditions persist or worsen. Further, the results of operations for a property in any one period may not be indicative of results in future periods, and the long-term performance of such property generally may not be comparable to, and cash flows may not be as predictable as, other properties owned by third parties in the same or similar industry.

Our tenant insurance and tenant protection plan businesses are, in some cases, subject to governmental regulation, which may adversely affect our results.

Depending on the jurisdiction, we provide either tenant insurance or a tenant protection plan to customers at our properties. These businesses, including the payments associated with these arrangements, may be subject to state-specific or provincial-specific governmental regulation. Such regulatory authorities generally have broad discretion to promulgate, interpret and implement regulations, to adopt new or additional licensing requirements, to grant, renew and revoke licenses and approvals, and to evaluate compliance with regulations through periodic examinations, audits, investigations and inquiries. In addition, there has been and may continue to be regulatory or private action in the jurisdictions in which we operate. The impact of such actions could adversely affect our business and results of operations.

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.

Material losses may occur in excess of insurance proceeds with respect to any property, as insurance may not be sufficient to fund the losses. However, there are types of losses, generally of a catastrophic nature, such as losses due to wars, acts of terrorism, earthquakes, floods, fires, hurricanes, pollution or environmental matters, which are either uninsurable or not economically insurable, or may be insured subject to limitations such as large deductibles or co-payments. InsuranceThese insurance risks associated with potential terrorist acts could sharply increase the premiums we pay for coverage against property and casualty claims. Additionally, mortgage lenders in some cases require that commercial property owners purchase specific coverage against terrorism as a condition for providing mortgage loans. It is uncertain whether such insurance policies will be available, or available at reasonable cost, which could inhibit our ability to finance or refinance our potential properties. In these instances, we may be required to provide other financial support, either through financial assurances or self-insurance, to cover potential losses. We cannot assure our stockholders that we will have adequate coverage for such losses. The Terrorism Risk Insurance Act of 2002 is designed for a sharing of terrorism losses between insurance companies and the federal government and requires that insurers make terrorism insurance available under their property and casualty insurance

24

policies, but this legislation does not regulate the pricing of such insurance. We cannot be certain how this act will impact us or what additional cost to us, if any, could result. If such an event damaged or destroyed one or more of our properties, we could lose both our invested capital and anticipated profits from such property.

Our joint venture investments could be adversely affected by our lack of sole decision-making authority.

We hold interests in certain properties through joint ventures. Some of these arrangements could be adversely affected by our lack of sole decision-making authority, our reliance on co-venturers financial conditions, and disputes between us and our co-venturers. We expect to continue our joint venture strategy by entering into more joint ventures for the purposes of developing new properties and acquiring properties with existing facilities. In such event, we would not be in a position to exercise sole decision-making authority regarding the property, partnership, joint venture, or other entity. In addition, investments in partnerships, joint ventures or other entities may, under certain circumstances, involve risks not present were a third party not involved, including the possibility that partners or co-venturers might become bankrupt or fail to fund their share of required capital contributions. Partners or co-venturers may have economic or other business interests or goals which are inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives. Such investments may also have the potential risk of impasses on decisions, such as a sale, because neither we nor the partner or co-venturer would have full control over the partnership or joint venture. Disputes between us and partners or co-venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and/or directors from focusing their time and efforts on our business. Consequently, actions by or disputes with partners or co-venturers might

result in subjecting properties owned by the partnership or joint venture to additional risk. In addition, we may in certain circumstances be liable for the actions of our third-party partners or co-venturers, which could harm our financial condition.

We disclose funds from operations and funds from operations, as adjusted, each a non-GAAP financial measure, in communications with investors, including documents filed with the SEC. However, funds from operations and funds from operations, as adjusted, are not equivalent to our net income or loss or cash flow from operations as determined under GAAP, and stockholders should consider GAAP measures to be more relevant to our operating performance.

We use, and we disclose to investors, funds from operations (“FFO”) and FFO, as adjusted, which are non-GAAP financial measures. FFO and FFO, as adjusted, are not equivalent to our net income or loss or cash flow from operations as determined in accordance with GAAP, and investors should consider GAAP measures to be more relevant in evaluating our operating performance and ability to pay distributions. FFO and FFO, as adjusted, differ from GAAP net income because FFO and FFO, as adjusted, exclude gains or losses from sales of property and asset impairment write downs, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. In determining FFO, as adjusted, we make further adjustments to FFO to exclude the effects of non-real estate related asset impairments and intangible amortization, acquisition related costs, other write-offs incurred in connection with acquisitions, contingent earnout expenses, accretion of fair value of debt adjustments, gains or losses from extinguishment of debt, accretion of deferred tax liabilities, realized and unrealized gains/losses on foreign exchange transactions, and gains/losses on foreign exchange and interest rate derivatives not designated for hedge accounting. FFO, as adjusted, also reflects adjustments for unconsolidated partnerships and jointly owned investments.

Because of these differences, FFO and FFO, as adjusted, may not be accurate indicators of our operating performance, especially during periods in which we are acquiring properties. In addition, FFO and FFO, as adjusted, are not indicative of cash flow available to fund cash needs and investors should not consider FFO and FFO, as adjusted, as alternatives to cash flows from operations or an indication of our liquidity or of funds available to fund our cash needs, including our ability to pay distributions to our stockholders.

Neither the SEC nor any other regulatory body has passed judgment on the acceptability of the adjustments that we use to calculate FFO and FFO, as adjusted. Also, because not all companies calculate FFO and FFO, as adjusted, the same way, comparisons with other companies may not be meaningful.

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.

All real property, including our self storage properties, and the operations conducted on real property are subject to federal, state, and local laws and regulations relating to environmental protection and human health and safety. These laws and regulations generally govern wastewater discharges, air emissions, the operation and removal of underground and above-ground storage tanks, the generation, use, storage, treatment, transportation, release, and disposal of solid and hazardous materials and wastes, and the remediation of contamination associated with disposals.contamination. Some of these laws and regulations may impose joint and several liability on customers, owners, or operators for the costs to investigate or remediate contaminated properties, regardless of fault or whether the acts causing the contamination were legal.legal at the time. This liability could be substantial. In addition, the presence of hazardous substances (including asbestos or asbestos-containing materials and mold), or the failure to properly remediate these substances, may expose us to legal actions, and may adversely affect our ability to sell or rent a property, or to pledge such property as collateral for future borrowings.

Some of these laws and regulations have been amended so as to require compliance with new or more stringent standards as of future dates. Compliance with new or more stringent laws or regulations or stricter interpretation of existing laws may require us to incur material expenditures. Future laws, ordinances or regulations may impose material environmental liability. Additionally, our customers’ activities, the existing condition of land when we buy it, operations in the vicinity of our properties, such as the presence of underground storage tanks, or activities of unrelated third parties may affect our properties. In addition, there are various local, state, and federal fire, health, life-safety, and similar regulations with which we may be required to comply, and that may subject us to liability in the form of fines or damages for noncompliance. Any material expenditures, fines, or damages we must pay will reduce our ability to continue to pay distributions at the current rate to our stockholders and may reduce the value of our stockholders’ investments.

We cannot assure our stockholders that the independent third party environmental assessments we obtain prior to acquiring any properties we purchase will reveal all environmental liabilities, or that a prior owner, occupant, or neighbor of a property did not create a material environmental condition not known to us. We also cannot assure that the current

environmental condition of our properties will not be affected by neighbors and occupants, by the condition of nearby properties, or by other unrelated third parties. We cannot predict what other environmental legislation or regulations will be enacted in the future, how existing or future laws or regulations will be administered or interpreted, or what environmental conditions may be found to exist in the future. WeFinally, we cannot assure our stockholders that our business, assets,

25

results of operations, liquidity, or financial condition will not be adversely affected by these laws, which may adversely affect cash available for distribution, and the amount of distributions to our stockholders.

Climate change may adversely affect our business, financial condition, cash flows and results of operations.

Climate change, including the impact of global warming, creates physical and financial risks. Physical risks from climate change include an increase in sea levels and changes in weather conditions, such as an increase in storm intensity and severity of weather (e.g., floods, tornadoes or hurricanes) and extreme temperatures. The occurrence of sea level rise or one or more natural disasters, such as floods, tornadoes, hurricanes, tropical storms, wildfires, and earthquakes (whether or not caused by climate change), could cause considerable damage to our properties, disrupt our operations and negatively affect our financial performance. To the extent any of these events results in significant damage to or closure of one or more of our properties, our operations and financial performance could be adversely affected through an inability to lease or re-lease the property. In addition, these events could result in significant expenses to restore or remediate a property, increases in fuel or other energy costs or a fuel shortage, and increases in the costs of (or making unavailable) insurance on favorable terms if they result in significant loss of property or other insurable damage. In addition, transition risks associated with new or more stringent laws or regulations or stricter interpretations of existing laws or regulations may require material expenditures by us. For example, various federal, state, and regional laws and regulations have been implemented or are under consideration to mitigate the effects of climate change caused by greenhouse gas emissions. Among other things, “green” building codes may seek to reduce emissions through the imposition of standards for design, construction materials, water and energy usage and efficiency, and waste management. Such codes could require us to make improvements to our properties, increase the costs of maintaining or improving our properties or developing new properties, or increase taxes and fees assessed on us or our properties.

Costs of complying with governmental laws and regulations, including those relating to regulations accommodating disabilities, may affect cash available for distribution.

We are subject to various rules, regulations and standards with respect to accommodations we must make for individuals with disabilities. For example, in the United States, under the Americans with Disabilities Act of 1990, or ADA, all public accommodations and commercial facilities are required to meet certain federal requirements related to access and use by disabled persons. We are also subject to similar requirements in Ontario, Canada, under the Accessibility for Ontarians with Disabilities Act, or AODA. Under these regulations, places of public accommodation, which include our self storage facilities, are required to comply with certain requirements related to access and use by disabled persons. These requirements could require removal of access barriers and could result in the imposition of injunctive relief, monetary penalties, or, in some cases, an award of damages. We will attempt to acquire properties that comply with such regulations or place the burden on the seller or other third party to ensure compliance with such regulations. However, we cannot assure our stockholders that we will be able to acquire properties or allocate responsibilities in this manner. If we cannot, our funds used for such compliance may affect cash available for distribution and the amount of distributions to our stockholders.

If we sell properties by providing financing to purchasers, defaults by the purchasers would adversely affect our cash flows.

In some instances, we may sell our properties by providing financing to purchasers. When we provide financing to purchasers, we will bear the risk that the purchaser may default, which could negatively impact our cash distributions to stockholders. Additionally, the distribution of the proceeds of sales to our stockholders, or their reinvestment in other assets, will be delayed until the promissory notes or other property we may accept upon the sale are actually paid, sold, refinanced, or otherwise disposed of. In some cases, we may receive initial down payments in cash and other property in the year of sale in an amount less than the selling price and subsequent payments will be spread over a number of years. If any purchaser defaults under a financing arrangement with us, it could negatively impact our ability to continue to pay distributions at the current rate to our stockholders.

Property taxes and insurance premiums may increase, which would adversely affect our net operating income and cash available for distributions.

Each of the properties we acquire will be subject to real property taxes.taxes and insurance premiums, including property insurance, liability insurance, and, in some cases, earthquake insurance. Some local real property tax assessors may seek to reassess some of our properties as a result of our acquisition of the property. From time to time, our property taxes may increase as property values or assessment rates change or for other reasons deemed relevant by the assessors. In addition, state or local governments may increase tax rates or assessment levels (See the risk factor immediately below).levels. Further, insurance premiums have recently increased and may continue to increase due to various factors, including inflation and natural disasters. Increases in real property taxes and insurance premiums will adversely affect our net operating income and cash available for distributions.

Our property taxes could increase due to reassessment or property tax rate changes.

Real property taxes on our properties may increase as our properties are reassessed by taxing authorities or as property tax rates change. For example, a current California law commonly referred to as Proposition 13 generally limits annual real estate tax increases on California properties to 2% of assessed value. Accordingly, the assessed value and resulting property tax we pay is less than it would be if the properties were assessed at current values. From time to time, proposals have been made to reduce the beneficial impact ofIf Proposition 13 particularly with respect to commercial property, which would include self-storage facilities.  While these initiatives have failed to pass to date, there can be no assurance that Proposition 13 will not beis repealed or amended at some point, which could causein a way that reduces its beneficial impact, our property tax expense tocould increase substantially for our properties located in California, adversely affecting our net operating income and cash flow from operations and net income.available for distributions.

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.

Revenues generated from any properties or other real estate investments we acquire or ventures we enter into relating to transactions involving assets located in markets outside the United States likely will be denominated in the local currency. Therefore, any investments we make outside the United States may subject us to foreign currency risk due to potential fluctuations in exchange rates between foreign currencies and the U.S. dollar. As a result, changes in exchange rates of any such foreign currency to U.S. dollars may affect our revenues, operating margins, and distributions and may also affect the book value of our assets and the amount of stockholders’ equity.

26

Changes in foreign currency exchange rates used to value a REIT’s foreign assets may be considered changes in the value of the REIT’s assets. These changes may adversely affect our ability to qualify as a REIT. Further, bank accounts in foreign currency which are not considered cash or cash equivalents may adversely affect our ability to qualify as a REIT.

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 have purchased and may continue to purchase properties in Canada. In addition, our Managed REITs own properties in Canada where we, through our subsidiaries, serve as the property manager. As a result, our financial results may be adversely affected by fluctuations in the Canadian Dollar/USD exchange rate. We cannot predict with any certainty changes in foreign currency exchange rates or our ability to mitigate these risks. Several factors may affect the Canadian Dollar/USD exchange rate, including:

These events and actions are unpredictable. In addition, the Canadian Dollar may not maintain its long term value in terms of purchasing power in the future. The resulting volatility in the Canadian Dollar/USD exchange rate could materially and adversely affect our performance.

We are subject to additional risks due to the location of any of the properties that we either own or operate in Canada.

In addition to currency exchange rates, the value of any properties we purchase in Canada may be affected by factors peculiar to the laws and business practices of Canada. Canadian laws and business practices may expose us to risks that are different from and in addition to those commonly found in the United States. Ownership and operation of foreign assets pose several risks, including, but not limited to the following:

27

Risks Associated with Debt Financing

We have broad authority to incur debt, and high debt levels could hinder our ability to continue to pay distributions at the current rate and could decrease the value of our stockholders’ investments.

Our board may approve unlimited levels of debt. High debt levels would cause us to incur higher interest charges, would result in higher debt service payments, and could be accompanied by restrictive covenants. These factors could limit the amount of cash we have available to distribute and could result in a decline in the value of our stockholders’ investments.

If we or the other parties to our loans breach covenants thereunder, such loan or loans could be deemed in default, which could accelerate our repayment date and materially adversely affect the value of our stockholders’ investment in us.

Certain of our loans are secured by first mortgages on some of our properties and other loans are secured by pledges of equity interests in the entities that own certain of our properties. Such loans also impose a number of financial or other covenant requirements on us. If we, or the other parties to these loans, should breach certain of those financial or other covenant requirements, or otherwise default on such loans, then the respective lenders, as the case may be, could accelerate our repayment dates. If we do not have sufficient cash to repay the applicable loan at that time, such lenders could foreclose on the property securing the applicable loan or take control of the pledged collateral, as the case may be. Such foreclosure could result in a material loss for us and would adversely affect the value of our stockholders’ investment in us. In addition, certain of these loans are cross-collateralized and cross-defaulted with each other such that a default under one loan would cause a default under the other loans. See Note 7 – Debt, and Note 16 – Subsequent Events of the Notes to the Consolidated Financial Statements for more information on such loans.

Discontinuation, reform, or replacement of LIBOR may adversely affect the amount of interest that we pay on our variable rate debt.

A significant portion of our borrowings are at variable rates of interest, primarily based on the London Interbank Offered Rate for deposits of U.S dollars (“LIBOR”). In July 2017, the United Kingdom Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. The Federal Reserve, in conjunction with the Alternative Reference Rates Committee (“ARRC”), a steering committee comprised of large U.S. financial institutions, announced replacement of U.S. dollar LIBOR with a new index calculated by short-term repurchase agreements, backed by U.S. Treasury securities called the Secured Overnight Financing Rate (“SOFR”). The first publication of SOFR was released in 2018. Whether or not SOFR attains market traction as a LIBOR replacement tool remains in question and the future of LIBOR remains uncertain.  Providing some clarification, in November 2020, the ICE Benchmark Administration (“IBA”) announced that it will consult on its intentions to cease the publication of one week and two month USD LIBOR following the LIBOR publication on December 31, 2021, and to cease the publication of the remaining USD LIBOR settings following the LIBOR publication on June 30, 2023, effectively extending the transition timeline. At this time, it is unclear what LIBOR or new methods of calculating LIBOR will look like after 2021.

In conjunction with the transition away from LIBOR, we and our lenders will cooperate in establishing an alternate rate of interest, which we would expect to be comparable to LIBOR on a historical basis prior to such determination. However, during the time that an alternate rate of interest is determined, we may be limited in our ability to draw upon Eurodollar Loans and may be required to draw upon alternative base rate loans. See Note 7 – Debt and Note 16 – Subsequent Events of the Notes to the Consolidated Financial Statements for more information on such loans. In addition, the U.S. Federal Reserve Board, in conjunction with the Alternative Reference Rates Committee, is considering replacing U.S. dollar LIBOR with a newly created index, calculated with a broad set of short-term repurchase agreements backed by treasury securities. It is not possible to predict the effect of the foregoing, including any related reforms or the establishment of alternative reference rates in the U.S. or elsewhere. To the extent these interest rates increase, our interest expense will increase, in which event we may have difficulties making interest payments and funding our other fixed costs, and our available cash flow for general corporate requirements may be adversely affected.

28

We have incurred and intend to continue to incur, mortgage indebtedness and other borrowings, which may increase our business risks.

We have placed, and intend to continue to place, permanent financing on our properties and we may obtain additional credit facilities or other similar financing arrangements in order to acquire additional properties. In particular, we have a Credit Facility with KeyBank, National Association of up to $700 million, of which approximately $568.7 million was outstanding as of December 31, 2023. We are also party to the Note Purchase Agreement, whereby we issued to the purchasers an aggregate of $150 million of secured notes payable. At issuance, the notes carried a fixed interest rate of 4.53%, which increased to 5.28% as a result of certain leverage thresholds. The notes will continue to accrue interest at a rate of 5.28% until certain leverage thresholds are met for two consecutive fiscal quarters, at which point, the rate will revert to 4.53% and remain at that interest rate through maturity. The credit facility and the notes are subject to a series of financial and other covenants. See Note 5 – Debt, for additional information. We may also decide to later further leverage our properties. We may incur mortgage debt and pledge all or some of our real properties as security for that debt to obtain funds to acquire real properties. If we default on our secured indebtedness, the lender may foreclose and we could lose our entire investment in the properties securing such loan, which could adversely affect distributions to our stockholders. To the extent lenders require us to cross-collateralize our properties, or our loan agreements contain cross-default provisions, a default under a single loan agreement could subject multiple properties to foreclosure.

In connection with the SST IV Merger, we assumed certain loans and entered into a new credit facility (See Note 16 Subsequent Events of the Notes to the Consolidated Financial Statements for more information on such loans). Accordingly, we may be subject to an increased risk that our cash flow could be insufficient to meet required payments on our debt. Our increased indebtedness as a result of the SST IV Merger, compared to our level of indebtedness prior to the SST IV Merger, could have important consequences to our stockholders, including:

In addition, we may borrow if we need funds to pay a desired distribution rate to our stockholders. We may also borrow if we deem it necessary or advisable to assure that we maintain our qualification as a REIT for federal income tax purposes. If there is a shortfall between the cash flow from our properties and the cash flow needed to service mortgage debt, then the amount available for distribution to our stockholders may be reduced.

If we or the other parties to our loans or secured notes payable, as applicable, breach covenants thereunder, such loan or loans or secured notes payable could be deemed in default, which could accelerate our repayment date and materially adversely affect the value of our stockholders’ investment in us.

Certain of our loans are secured by first mortgages on some of our properties, and other loans and our secured notes payable are secured by pledges of equity interests in the entities that own certain of our properties. Such loans and our secured notes payable also impose a number of financial or other covenant requirements on us. If we, or the other parties to these loans or notes, should breach certain of those financial or other covenant requirements, or otherwise default on such loans or notes, then the respective lenders or noteholders, as the case may be, could accelerate our repayment dates. If we do

not have sufficient cash to repay the applicable loan or note at that time, such lenders or noteholder could foreclose on the property securing the applicable loan or note or take control of the pledged collateral, as the case may be. Such foreclosure could result in a material loss for us and would adversely affect the value of our stockholders’ investment in us. In addition, certain of our loans are cross-collateralized and cross-defaulted with each other such that a default under one loan would cause a default under the other loans.

Our obligation to make balloon payments could increase the risk of default.

Our debt may have balloon payments of up to 100% of the principal amount of such loans due on the respective maturity dates. Thus, such debt will have a substantial payment due at the scheduled maturity date, unless previously prepaid or refinanced. Loans with a substantial remaining principal balance on their stated maturity involve greater degrees of risk of non-payment at stated maturity than fully amortizing loans. As a result, our ability to repay such loans on their respective maturity dates will largely depend upon our ability either to prepay such loans, refinance such loans or to sell, to the extent permitted, all or a portion of the properties encumbered by such loans, if any. Our ability to accomplish any of these goals will be affected by a number of factors at the time of attempted prepayment, refinancing, or sale, including, but not limited to: (i) the availability of, and competition for, credit for commercial real estate; (ii) prevailing interest rates; (iii) the net operating income generated by our properties; (iv) the fair market value of our properties; (v) our equity in our properties; (vi) our financial condition; (vii) the operating history and occupancy level of our properties; (viii) the tax laws; and (ix) the prevailing general and regional economic conditions.

29

Lenders have required and will likely continue to require us to enter into restrictive covenants relating to our operations, which could limit our ability to continue to pay distributions to our stockholders.

When providing financing, lenders often impose restrictions on us that affect our distribution and operating policies and our ability to incur additional debt. Loan documents we enter into may contain covenants that limit our ability to further mortgage the property or discontinue insurance coverage. We are also required to obtain the affirmative vote of the holders of a majority of the Series A Convertible Preferred Stock before entering into certain transactions. These or other limitations may adversely affect our flexibility and limit our ability to continue to pay distributions at the current rate to our stockholders. If the limits set forth in these covenants prevent us from satisfying our distribution requirements, we could fail to qualify for federal income tax purposes as a REIT. If the limits set forth in these covenants do not jeopardize our qualification for taxation as a REIT, but prevent us from distributing 100% of our REIT taxable income, we will be subject to U.S. federal income tax, and potentially a nondeductible excise tax, on the retained amounts.

Increases in interest rates could increase the amount of our debt payments and adversely affect our ability to continue to pay distributions at the current rate to our stockholders.

We currently have outstanding debt payments which are indexed to variable interest rates. We may also incur additional debt or issue additional preferred equity in the future which rely on variable interest rates. Increases in these variable interest rates have occurred and may continue in the future would increasewhich increases our interest costs and preferred equity distribution payments, which would likely reduce our cash flows and potentially negatively impact our ability to continue to pay distributions at the current rate to our stockholders. In addition, if we need to make payments on instruments which contain variable interest during periods of rising interest rates, we could be required to liquidate one or more of our investments in properties at times that may not permit realization of the maximum return on such investments.

Further, as a result of the discontinuation of the London Interbank Offered Rate, or LIBOR, beginning in 2021, our variable rate debt is currently indexed to the Secured Overnight Financing Rate, or SOFR. SOFR is a relatively new reference rate, has a very limited history and is based on short-term repurchase agreements, backed by Treasury securities. Changes in SOFR can be volatile and difficult to predict, and there can be no assurance that SOFR will perform similarly to the way LIBOR would have performed at any time. As a result, the amount of interest we may pay on our credit facilities is difficult to predict.

Disruptions in the credit markets could have a material adverse effect on our results of operations, financial condition, and ability to pay distributions to our stockholders.

Domestic and international financial markets have experienced significant disruptions in the past which were brought about in large part by failures in the U.S. banking system. These disruptions severely impacted the availability of credit and contributed to rising costs associated with obtaining credit. Future credit market disruptions including those associated with the worldwide COVID-19 outbreak, may have similar effects or otherwise make obtaining additional and replacement external sources of liquidity more difficult and more costly, if available at all. If debt financing is not available on terms and conditions we find acceptable, we may not be able to obtain financing

for investments. If these disruptions in the credit markets resurface, our ability to borrow monies to finance the purchase of, or other activities related to, real estate assets will be negatively impacted. If we are unable to borrow monies on terms and conditions that we find acceptable, we may be forced to use a greater proportion of our Offering proceeds to finance our acquisitions, reduce the number of properties we can purchase, and/or dispose of some of our assets. These disruptions could also adversely affect the return on the properties we do purchase. In addition, if we pay fees to lock in a favorable interest rate, falling interest rates or other factors could require us to forfeit these fees. All of these events would have a material adverse effect on our results of operations, financial condition, and ability to pay distributions.

Risks Associated with Our Managed REIT Platform

Revenue and earnings from the Managed REIT Platform are uncertain.

Increasing our revenue from the Managed REIT Platform is dependent in large part on the ability to raise capital in offerings for existing or future Managed REITs or other future programs, as well as on our ability to make investments that meet the investment criteria of existing and future entities, both of which are subject to uncertainty with respect to capital market and real estate market conditions. This uncertainty could have an adverse impact on our earnings. Moreover, revenue generated from asset management fees, property management fees, and other fees and distributions relating to the Managed REITs’ offerings and the investment and management of their respective assets may be affected by factors that include not only our ability to increase the Managed REITs’ portfolio of properties under management, but also changes in valuation of those properties, sales of the Managed REIT properties and assets and our ability to successfully operate the Managed REIT properties.

The Managed REITs may not generate sufficient revenue or may incur significant debt, which either due to liquidity problems or restrictive covenants contained in their borrowing agreements could restrict their ability to pay or reimburse fees and expenses owed to us when due. In addition, the revenue payable by the Managed REITs is subject to certain limits set forth in their respective advisory agreements, which may limit the growth of our revenue. Furthermore, our ability to earn

30

certain subordinated distributions from the Managed REITs is tied to providing liquidity events for the Managed REITs. Our ability to provide such liquidity events, and to do so under circumstances that will satisfy the applicable subordination requirements, will depend on market conditions at the relevant time, which may vary considerably over a period of years. If we are unable to satisfy such subordination requirements, certain equity interests we hold in the Managed REITs may be impaired.

Because the revenue streams from the advisory agreements with the Managed REITs are subject to limitation or cancellation, any such termination could adversely affect our financial condition, cash flow and the amount available for distributions to our common stockholders.

Our advisory agreement with the SST VI Advisor is renewable annually, and our advisory agreement with the SSGT II Advisor has an initial term of 10 years and is renewable annually thereafter, and each may generally be terminated by each Managed REIT, without cause or penalty, upon 60 days’ written notice. There can be no assurance that the advisory agreements will be renewed before they expire or that the advisory agreements will not be terminated. Any such non-renewal or termination could adversely affect our financial condition, cash flow and the amount available for distributions to our common stockholders.

We will face conflicts of interest relating to the purchase of properties, including conflicts with the Managed REITs, and there can be no assurance that our investment allocation policy will adequately address all of the conflicts that may arise or that it will address such conflicts in a manner that is more favorable to us than to the Managed REITs.

We own the entities that serve as the sponsor and advisor to the Managed REITs, which have investment objectives similar to ours, and we may be buying properties at the same time as one or more of the Managed REITs, or other programs managed by us, our officers, our key personnel or our subsidiaries (the “Other Programs”). Accordingly, we will have conflicts of interest in allocating potential properties, acquisition expenses, management time, services, and other functions between various existing enterprises or future enterprises with which the Managed REITs may be or become involved. SSGT II is a private Managed REIT that invests in self storage properties and had assets of approximately $141 million as of December 31, 2020, and SST VI is a private Managed REIT that was in its early stage of operations in early 2021.

While we have adopted an investment allocation policy in an effort to appropriately allocate acquisitions among us, the Managed REITs and the Other Programs, there can be no assurance that such allocation policy will adequately address all of the conflicts that may arise or that it will address such conflicts in a manner that is more favorable to us than to the Managed REITs or the Other Programs. In addition, conflicts of interest may exist in the valuation of our investments and regarding decisions about the allocation of specific investment opportunities among us, the Managed REITs and the Other Programs and the allocation of fees and costs among us, the Managed REITs and the Other Programs. To the extent we fail to appropriately deal with any such conflicts, it could negatively impact our reputation and ability to raise additional funds or result in potential litigation against us.

A subsidiary of ours is the sponsor of the Managed REITs and may sponsor additional future programs. As a result, we could be subject to any litigation that may arise by investors in those entities or the respective operations of those entities.

In the course of their operations, the Managed REITs and the other future programs may be subject to lawsuits. We may be named in such lawsuits as the sponsor of such entities and may, in some instances, be found to be subject to liability. In such an instance, our ability to seek reimbursement or indemnification from such programs may be limited. If we are subject to significant legal expenses, it could have an adverse effect on our financial condition.

Federal Income Tax Risks

Failure to continue to qualify as a REIT would adversely affect our operations and our ability to continue to pay distributions at our current level as we will incur additional tax liabilities.

We believe we operate in a manner that allows uselected to qualifybe taxed as a REIT for U.S. federal income tax purposes undercommencing with our taxable year ended December 31, 2014. We believe that our organization and method of operation has enabled and will continue to enable us to meet the Code.requirements for qualification and taxation as a REIT for U.S. federal income tax purposes. Qualification as a REIT involves highly technical and complex Code provisions for which there are only limited judicial and administrative interpretations. Our qualification as a REIT will depend upon our ability to meet, through investments, actual operating results, distributions and satisfaction of specific stockholder rules, the various tests imposed by the Code.

31

If we fail to qualify as a REIT for any taxable year, we will be subject to federal income tax and any applicable alternative minimum tax on our taxable income at the regular corporate rates.rate, which would reduce our net earnings available for investment or distribution to stockholders. If our REIT status is terminated for any reason, we would generally be disqualified from treatment as a REIT for the four taxable years following the year of such termination. Losing our REIT status would reduce our net earnings available for investment or distribution to stockholders because of the additional tax liability. In addition, distributions to stockholders would no longer qualify for the distributions paid deduction, and we would no longer be required to make distributions.distributions to stockholders, and distributions we do make would no longer qualify for the dividends paid deduction. In addition, if we fail to qualify as a REIT, we may be required to repurchase the Series A Convertible Preferred Stock. If this occurs, we mightmay be required to borrow funds or liquidate some investments in order to pay the applicable tax and redeem holders of the Series A Convertible Preferred Stock.

In the event that any REIT we have acquired in a nontaxable merger transaction, including SST IV or SSGT II, is found to have failed to qualify as a REIT for any period prior to our acquisition, we may be liable for certain entity level taxes of such acquired REIT for such tax periods as a result of such acquisition, that could substantially reduce our cash available for distribution, including cash available to pay dividends to our stockholders, because:because the acquired REIT would be subject to U.S. federal corporate income tax on its net income for the years it did not qualify for taxation as a REIT (and, for such years, would not be allowed a deduction for dividends paid to stockholders in computing its taxable income).

In addition, if any such acquired REIT, including SST IV or SSGT II, failed to qualify as a REIT for any taxable period prior to our acquisition, in the event of a taxable disposition of an asset formerly held by such acquired REIT during a period of up to five years following our acquisition, we would be subject to U.S. federal corporate income tax with respect to any built-in gain inherent in such asset as of the closing of our acquisition.

Qualification as a REIT is subject to the satisfaction of tax requirements and various factual matters and circumstances that are not entirely within our control. New legislation, regulations, administrative interpretations or court decisions could change the tax laws with respect to qualification as a REIT or the federal income tax consequences of being a REIT. Our failure to continue to qualify as a REIT would adversely affect the return of our stockholders’ investment.

To qualify as a REIT, and to avoid the payment of U.S. federal income and excise taxes and maintain our REIT status, we may be forced to borrow funds, use proceeds from the issuance of securities, or sell assets to pay distributions, which may result in our distributing amounts that may otherwise be used for our operations.

To obtain the favorable tax treatment accorded to REITs, we normally will be required each year to distribute to our stockholders at least 90% of our REIT taxable income, generally determined without regard to the deduction for distributionsdividends paid and by excluding net capital gains. We will be subject to federal income tax on our undistributed REIT taxable income and net capital gain and subject to a 4% nondeductible excise tax on any amount by which distributionsdividends we pay with respect to any calendar year are less than the sum of (1) 85% of our ordinary income, (2) 95% of our capital gain net income, and (3) 100% of our undistributed income from prior years. These requirements could cause us to distribute amounts that otherwise would be spent on the acquisition, maintenance or development of properties and it is possible that we might be required to borrow funds, use proceeds from the issuance of securities or sell assets in order to distribute enough of our taxable income to maintain our REIT status and to avoid the payment of federal income and excise taxes. We may be required to make

distributions to stockholders at times it would be more advantageous to reinvest cash in our business or when we do not have cash readily available for distribution, and we may be forced to liquidate assets on terms and at times unfavorable to us. These methods of obtaining funding could affect future distributions by increasing operating costs and decreasing available cash. In addition, such distributions may constitute a return of investor’s capital for federal income tax purposes.

Our stockholders may have tax liability on distributions they elect to reinvest in our common stock.

If our stockholders participate in our distribution reinvestment plan, our stockholders will be deemed to have received, and for income tax purposes will be taxed on, the amount reinvested in common stock to the extent the amount reinvested was not a tax-free return of capital. As a result, unless our stockholders are a tax-exempt entity,entities, our stockholders may have to use funds from other sources to pay their tax liability on the value of the common stock received.

If any of our partnerships fails to maintain its status as a partnership for federal income tax purposes, its income would be subject to taxation and our REIT status wouldmay be terminated.

32

We intend to maintain the status of our partnerships, including our Operating Partnership, as partnerships for federal income tax purposes. However, if the Internal Revenue Service (IRS) were to successfully challenge the status of any of our partnerships as a partnership, it would be taxable as a corporation. Such an event would reduce the amount of distributions that such partnership could make to us. This would also result in our losing REIT status and becoming subject to a corporate level tax on our own income. This would substantially reduce our cash available to pay distributions and the return on our stockholders’ investments. In addition, if any of the entities through which any of our partnerships owns its properties, in whole or in part, loses its characterization as a partnership for federal income tax purposes, it generally would be subject to taxation as a corporation, thereby reducing distributions to such partnership. Such a recharacterization of any of our partnerships or an underlying property owner could also threatencause us to fail to qualify as a REIT, which would substantially reduce our abilitycash available to maintain REIT status.pay distributions and the return on our stockholders’ investments.

In certain circumstances, we may be subject to federal and state income taxes as a REIT, which would reduce our cash available for distribution to our stockholders.

Even if we qualify and maintain our status as a REIT, we may be subject to federal income taxes or state taxes. For example, net income from a “prohibited transaction” will be subject to a 100% tax. We may not be able to make sufficient distributions to avoid excise taxes applicable to REITs. We may also decide to retain income we earn from the sale or other disposition of our property and pay income tax directly on such income. In that event, our stockholders would be treated as if they earned that income and paid the tax on it directly. However, stockholders that are tax-exempt, such as charities or qualified pension plans, would have no benefit from their deemed payment of such tax liability. We may also be subject to state and local taxes on our income or property, either directly, at the level of our Operating Partnership, or at the level of any other companies through which we indirectly own our assets. Any federal or state taxes we pay will reduce our cash available for distribution to our stockholders.

We may be required to pay some taxes due to actions of our taxable REIT subsidiaries, which would reduce our cash available for distribution to our stockholders.

Any net taxable income earned directly by our taxable REIT subsidiaries, or through entities that are disregarded for federal income tax purposes as entities separate from our taxable REIT subsidiaries,TRSs, will be subject to federal and possibly state corporate income tax. We have elected to treat SmartStop TRS, Inc. as a taxable REIT subsidiary,TRS, and we may elect to treat other subsidiaries as taxable REIT subsidiariesTRSs in the future. In this regard, several provisions of the laws applicable to REITs and their subsidiaries ensure that a taxable REIT subsidiaryTRS will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to deduct certain interest payments made to an affiliated REIT. In addition, the REIT has to pay a 100% penalty tax on some payments that it receives or on some deductions taken by a taxable REIT subsidiaryTRS if the economic arrangements between the REIT, the REIT’s customers, and the taxable REIT subsidiaryTRS are not comparable to similar arrangements between unrelated parties. Finally, some state and local jurisdictions may tax some of our income even though as a REIT we are not subject to federal income tax on that income, because not all states and localities follow the federal income tax treatment of REITs. To the extent that we and our affiliates are required to pay federal, state, and local taxes, we will have less cash available for distributions to our stockholders.

Distributions to tax-exempt investors may be classified as unrelated business taxable income.

Neither ordinary nor capital gain distributions with respect to our common stock, nor gain from the sale of common stock, should generally constitute unrelated business taxable income, (“UBTI”)or UBTI, to a tax-exempt investor. However, there are certain exceptions to this rule. In particular:

33

Complying with the REIT requirements may cause us to forego otherwise attractive opportunities.

To qualify as a REIT for federal income tax purposes, we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts we distribute to our stockholders and the ownership of shares of our common stock. We may be required to make distributions to stockholders at disadvantageous times or when we do not have funds readily available for distribution, or we may be required to liquidate otherwise attractive investments in order to comply with the REIT tests. Thus, compliance with the REIT requirements may hinder our ability to operate solely on the basis of maximizing profits.

Legislative

To maintain our REIT qualification, we may be forced to borrow funds during unfavorable market conditions.

In order to maintain our REIT qualification and avoid the payment of income and excise taxes, we may need to borrow funds to meet the REIT distribution requirements even if the then prevailing market conditions are not favorable for these borrowings. These borrowing needs could result from, among other things, timing differences between the actual receipt of cash and inclusion of income for U.S. federal income tax purposes, or regulatory actionthe effect of non-deductible capital expenditures, the creation of reserves or required debt or amortization payments. These sources, however, may not be available on favorable terms or at all. Our access to third-party sources of capital depends on a number of factors, including the market’s perception of our growth potential, current debt levels, and our current and potential future earnings. We cannot assure you that we will have access to such capital on favorable terms at the desired times, or at all, which may cause us to curtail investment activities and/or to dispose of assets at inopportune times, and could adversely affect investors.our financial condition, results of operations, cash flows, and our ability to pay distributions to our stockholders.

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.

Individuals with incomes below certain thresholds are subject to taxation at a 15% qualified dividend rate.rate for federal income tax purposes. For those with income above such thresholds, the qualified dividend rate is 20%. These tax rates are generally not applicable to distributionsdividends paid by a REIT, unless such distributionsdividends represent earnings on which the REIT itself has been taxed. As a result, distributionsdividends (other than capital gain distributions)dividends) we pay to individual investors generally will be subject to the tax rates that are otherwise applicable to ordinary income for federal income tax purposes, subject to a 20% deduction for REIT dividends available under “An Actof up to provide reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018” (the “2017 Tax Act”)20%. This disparity in tax treatment may make an investment in our shares comparatively less attractive to individual investors than an investment in the shares of non-REIT corporations, and could have an adverse effect on the value of our common stock. Our stockholders are urged to consult with their own tax advisor with respect to the impact of recent legislation on their investment in our common stock and the status of legislative, regulatory, or administrative developments and proposals and their potential effect on an investment in our common stock.

Foreign purchasers of our common stock may be subject to FIRPTA tax upon the sale of their shares.

A foreign person disposing of a U.S. real property interest, including shares of a U.S. corporation whose assets consist principally of U.S. real property interests, is generally subject to a tax, known as FIRPTA tax, on the gain recognized on the disposition. Such FIRPTA tax does not apply, however, to the disposition of stock in a REIT if the REIT is “domestically controlled.” A REIT is “domestically controlled” if less than 50% of the REIT’s stock, by value, has been owned directly or indirectly by persons who are not qualifying U.S. persons during a continuous five-year period ending on the date of disposition or, if shorter, during the entire period of the REIT’s existence.

We believe, but cannot assure our stockholdersguarantee, that we will qualify asbe a “domestically controlled” REIT. If we were to fail to so qualify, gain realized by foreign investors on a sale of our shares would be subject to FIRPTA tax, unless our shares were traded on an established securities market and the foreign investor did not at any time during a specified testing period directly or indirectly own more than 10% of the value of our outstanding common stock.

Legislative or other actions affecting REITs materially and adversely affect our stockholders and us.

The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury. Changes to the tax laws, with or without retroactive application, could materially and adversely affect our stockholders and us. We cannot predict how changes in the tax laws might affect our investors or us. New legislation, Treasury Regulations, administrative interpretations or court decisions could significantly and negatively affect our ability to qualify as a REIT or the federal income tax consequences of such qualification, or the federal income tax consequences of an investment in us. Also, the law relating to the tax treatment of other entities, or an investment in other entities, could change, making an investment in other entities more attractive relative to an investment in a REIT.

ERISA Risks

If our assets are deemed to be plan assets, we may be exposed to liabilities under Title I of Employee Retirement Income Security Act of 1974, or ERISA, and the Code.

In some circumstances where an ERISA plan holds an interest in an entity, the assets of the entity are deemed to be ERISA plan assets unless an exception applies. This is known as the “look-through rule.” Under those circumstances, the obligations and other responsibilities of plan sponsors, plan fiduciaries and plan administrators, and of parties in interest and disqualified persons, under Title I of ERISA or Section 4975 of the Code, may be applicable, and there may be liability under these and other provisions of ERISA and the Code. We believe that we will meet the “publicly-offered securities” exception and the “operating company” exception under the plan asset regulations. We note, however, that because certain limitations are imposed upon the transferability of shares of our common stock so that we may qualify as a REIT, and perhaps for other reasons, it is possible that these exceptions may not apply. If that is the case, and if we are exposed to liability under ERISA or the Code, our performance and results of operations could be adversely affected.

There are special considerations that apply to qualified pension or profit-sharing trusts or IRAs investing in our shares which could cause an investment in our company to be a prohibited transaction and could result in additional tax consequences.

If our stockholders are investing the assets of a qualified pension, profit-sharing, 401(k), Keogh, or other qualified retirement plan or the assets of an IRA in our common stock, they should satisfy themselves that, among other things:

Persons investing the assets of employee benefit plans, IRAs, and other tax-favored benefit accounts should consider ERISA and related risks of investing in the shares.

34

ERISA and Code Section 4975 prohibit certain transactions that involve (1) certain pension, profit-sharing, employee benefit, or retirement plans or individual retirement accounts and Keogh plans, and (2) any person who is a “party-in-interest” or “disqualified person” with respect to such a plan. Consequently, the fiduciary of a plan contemplating an investment in the shares should consider whether we, any other person associated with the issuance of the shares, or any of their affiliates is or might become a “party-in-interest” or “disqualified person” with respect to the plan and, if so, whether an exemption from such prohibited transaction rules is applicable. In addition, the Department of Labor (“DOL”) plan asset regulations provide that, subject to certain exceptions, the assets of an entity in which a plan holds an equity interest may be treated as assets of an investing plan, in which event the underlying assets of such entity (and transactions involving such

assets) would be subject to the prohibited transaction provisions. We intend to take such steps as may be necessary to qualify us for one or more of the exemptions available, and thereby prevent our assets as being treated as assets of any investing plan.

ITEM 1C.CYBERSECURITY

We take a comprehensive approach to cybersecurity and prioritize the security and integrity of our data, including those of our customers and other stakeholders, as a top priority. Our board of directors (in particular our audit committee) and our management are actively involved in the oversight of our risk management program, of which cybersecurity represents an important component. As described in more detail below, we have established policies, standards, processes and practices for assessing, identifying, and managing material risks from cybersecurity threats. We have devoted significant resources to implement and maintain security measures to meet regulatory requirements and stakeholder expectations, and we intend to continue to make appropriate investments to maintain the security and integrity of our data. There can be no guarantee that our established policies, standards, processes and practices will be properly followed in every instance or that they will be effective at mitigating all cybersecurity threats. Although our risk factors include further detail about the material cybersecurity risks we face, we believe that risks from cybersecurity threats, have not materially affected our business to date. We can provide no assurance that there will not be incidents in the future or that they will not materially affect us, including our business, results of operations, or financial condition.

Risk Management and Strategy

Our policies, standards, processes and practices for assessing, identifying, and managing material risks from cybersecurity threats are integrated into our overall risk management process and are based on frameworks established by the National Institute of Standards and Technology (“NIST”), the International Organization for Standardization and other applicable industry standards and best practices. Our cybersecurity program in particular focuses on the following key areas:

Collaboration

Our cybersecurity risks are identified and addressed through a comprehensive, cross-functional approach. Key security, risk, and compliance stakeholders meet regularly to develop strategies for preserving the confidentiality, integrity and availability of Company and customer information, identifying, preventing and mitigating cybersecurity threats. We maintain controls and procedures that are designed to ensure prompt escalation of certain cybersecurity incidents so that decisions regarding public disclosure and reporting of such incidents can be made by management and our board of directors in a timely manner.

Risk Assessment

At least annually, we conduct a cybersecurity risk assessment that takes into account information from internal stakeholders, known security vulnerabilities, and other external sources (e.g., reported security incidents that have impacted other companies, industry trends, and evaluations by third parties and consultants). The results of the assessment are used to drive alignment on, and prioritization of, initiatives to enhance our security controls, make recommendations to improve processes, and updates are presented to our board of directors and members of management, as appropriate.

Technical Safeguards

We regularly assess and deploy technical safeguards designed to protect our information systems from cybersecurity threats. Such safeguards are regularly evaluated and improved based on vulnerability assessments, cybersecurity threat intelligence and other developing cybersecurity practices.

Incident Response and Recovery Planning

We have established comprehensive incident response and recovery plans and continue to evaluate the effectiveness of those plans. Our incident response and recovery plans address and guide our response to a cybersecurity incident.

Third-Party Risk Management
