STATEMENT ON FORWARD-LOOKING INFORMATION

Certain information presented in this Annual Report on Form 10-K (this “annual report”) may contain “forward-looking statements” within the meaning of the federal securities laws, including the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements concerning Global Self Storage, Inc.'s (the "Company") plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions, and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as “believes,” “plans,” “intends,” “expects,” “estimates,” “may,” “will,” “should,” or “anticipates,” or the negative of such terms or other comparable terminology, or by discussions of strategy. All forward-looking statements made by the Company involve known and unknown risks, uncertainties and other factors, many of which are beyond the control of the Company, which may cause the Company’s actual results to be materially different from those expressed or implied by such statements. The Company may also make additional forward-looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by the Company or on its behalf, are also expressly qualified by these cautionary statements. All forward-looking statements, including without limitation, the Company’s examination of historical operating trends and estimates of future earnings, are based upon the Company’s current expectations and various assumptions. The Company’s expectations, beliefs and projections are expressed in good faith and it believes there is a reasonable basis for them, but there can be no assurance that the Company’s expectations, beliefs and projections will result or be achieved. All forward-looking statements apply only as of the date made. Except as required by law, the Company undertakes no obligation to publicly update or revise forward-looking statements which may be made to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.

There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this report. Any forward-looking statements should be considered in light of the risks referenced in “Item 1A. Risk Factors” and in our other filings with the Securities and Exchange Commission (the “SEC”). Such factors include, but are not limited to:

•

general risks associated with the ownership and operation of real estate, including changes in demand, risks related to redevelopment (including expansion) of self storage properties, potential liability for environmental contamination, natural disasters and adverse changes in tax, real estate and zoning laws and regulations;

•

risks associated with downturns in the national and local economies in the markets in which we operate, including risks related to current economic conditions and the economic health of our customers;

•

the impact of competition from new and existing self storage and commercial properties and other storage alternatives;

•

risks related to the successful evaluation, financing, integration, and managing of acquired and redeveloped properties into our existing operations;

•

risks related to our redevelopment of properties and expansions and related lease up at our existing properties and/or participation in joint ventures;

•

risks of ongoing litigation and other legal and regulatory actions, which may divert management’s time and attention, require us to pay damages and expenses or restrict the operation of our business;

•

the impact of the regulatory environment under national, state, and local laws and regulations including, without limitation, those governing the environment, taxes and our tenant reinsurance business and real estate investment trusts (“REITs”), and risks related to the impact of new laws and regulations;

•

risk of increased tax expense associated either with a possible failure by us to qualify as a REIT, or with challenges to intercompany transactions with our taxable REIT subsidiaries;

•

changes in federal or state tax laws related to the taxation of REITs, which could impact our status as a REIT;

•

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

•

security breaches or a failure of our networks, systems or technology;

•

risks related to obtaining and maintaining financing arrangements on favorable terms;

•

market trends in our industry, interest rates, the debt and lending markets or the general economy;

•

the timing of acquisitions and execution on our acquisition pipeline;

•

general volatility of the securities markets in which we participate;

•

changes in the value of our assets;

•

changes in interest rates and the degree to which our hedging strategies may or may not protect us from interest rate volatility;

•

increasing inflation;

•

risks related to continuing to qualify and maintain our qualification as a REIT for U.S. federal income tax purposes;

•

availability of qualified personnel;

•

difficulties in raising capital at a reasonable cost;

•

fiscal policies or inaction at the U.S. federal government level, which may lead to federal government shutdowns or negative impacts on the U.S. economy;

•

estimates relating to our ability to make distributions to our stockholders in the future; and

•

economic uncertainty due to the impact of terrorism, infectious or contagious diseases or pandemics, or war.

RISK FACTOR SUMMARY

An investment in our securities involves a high degree of risk. You should carefully consider the risks summarized in Item 1A, “Risk Factors” included in this report. These risks include, but are not limited to, the following:

Risks Related to our Self Storage Properties and our Business

•

Adverse economic or other conditions in the markets in which we do business and more broadly could negatively affect our occupancy levels and rental rates and therefore our operating results.

•

Our storage leases are relatively short-term in nature, which exposes us to the risk that we may have to re-lease our units and we may be unable to do so on attractive terms, on a timely basis or at all.

•

Our property taxes could increase due to various reasons, including a reassessment, which could adversely impact our operating results and cash flow.

•

We face competition from other self storage properties, which may adversely impact the markets in which we invest and in which our self storage properties operate.

•

Rental revenues are 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 or if we owned a larger number of self storage properties.

•

We may acquire properties subject to liabilities which may adversely impact our operating results.

•

Our investments in redevelopment projects may not yield anticipated returns which could adversely impact our economic performance.

•

We may be unable to make distributions in the future, maintain our current level of distributions or increase distributions over time.

•

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security breach through cyber-attacks, cyber-intrusions, or other methods could disrupt our information technology networks and related systems and harm our business.

•

Major public health issues and related disruptions in the U.S. and global economy and financial markets could adversely impact or disrupt our financial condition and results of operations.

Risks Related to Our Debt Financings

•

We depend on external sources of financing that are outside of our control, which could adversely affect our ability to acquire or redevelop properties, satisfy our debt obligations and/or make distributions to stockholders.

•

The terms and covenants relating to our indebtedness could adversely impact our economic performance.

Risks Related to Our Qualification as a REIT

•

Our failure to qualify or remain qualified as a REIT would subject us to U.S. federal income tax and applicable state and local taxes, which would reduce the amount of operating cash flow available for distribution to stockholders.

•

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

•

Failure to make required distributions would subject us to tax, which would reduce the operating cash flow available for distribution to stockholders.

•

We may not have cash available to make distributions.

Risks Related to Our Common Stock

•

The future sales of shares of our common stock may depress the price of our common stock and dilute stockholders’ beneficial ownership.

•

Any future offerings of debt, which would be senior to our common stock upon liquidation, and/or preferred equity securities which may be senior to our common stock for purposes of dividend distributions or upon liquidation, may adversely affect the market price of our common stock.

•

The market price and trading volume of our common stock may vary substantially.

PART I

Item 1. Business.

General

Global Self Storage, Inc. (the “Company”) is a self-administered and self-managed real estate investment trust (“REIT”) that owns, operates, manages, acquires, and redevelops self storage properties (“stores” or “properties”) in the United States. Our stores are designed to offer affordable, easily accessible, and secure storage space for residential and commercial customers. As of December 31, 2025, the Company owned and operated, or managed, through its wholly owned subsidiaries, thirteen stores located in Connecticut, Illinois, Indiana, New York, Ohio, Pennsylvania, South Carolina, and Oklahoma. The Company was formerly registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as a non-diversified, closed end management investment company. The Securities and Exchange Commission’s (“SEC”) order approving the Company’s application to deregister from the 1940 Act was granted on January 19, 2016. On January 19, 2016, the Company changed its name to Global Self Storage, Inc. from Self Storage Group, Inc., changed its SEC registration from an investment company to an operating company reporting under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and listed its common stock on NASDAQ under the symbol “SELF”.

The Company was incorporated on December 12, 1996 under the laws of the state of Maryland. The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that the Company continues to qualify as a REIT, it will not generally be subject to U.S. federal income tax, with certain limited exceptions, on its taxable income that is distributed to its stockholders.

Business Activities

As of December 31, 2025, the Company had 36 total employees and owned and operated, or managed, through its wholly owned subsidiaries, thirteen stores. As of December 31, 2025, these properties totaled 966,567 net leasable square feet and offered 7,044‬ storage units. In addition to traditional and climate-controlled units, many of the properties feature both covered and outside auto/RV/boat storage. The Company invests in stores by acquiring stores through its wholly owned subsidiaries and operates primarily in one segment: rental operations.

We continue to evaluate and enact a range of new initiatives and opportunities in order to help enable us to maximize our stores’ financial performance and stockholder value. Our strategies in seeking to maximize our stores’ financial performance and stockholder value include, among others, the following:

•

continue to implement and refine our move-in rate management systems in seeking to maximize occupancies and thus revenue derived from our store portfolio;

•

continue to implement and refine our proprietary existing tenant revenue rate management program in seeking to maximize revenue per leased square foot from our store portfolio;

•

continue to implement and refine our digital, drive-by, and referral marketing programs in seeking to attract more and higher quality (e.g., credit card paying) customers to our stores at a lower net cost; and

•

continue to pursue the acquisition of single stores and small portfolios that we believe can add stockholder value.

Our stores are generally located in densely populated and high traffic areas near major roads and highways. All of our stores display prominent road signage and most feature LED marquee boards describing the store features and move-in rent specials. Our stores are generally located in areas with strict zoning laws and attentive planning boards which make it difficult for our competition to develop new properties near ours. As we evaluate potential stores for acquisition, we seek stores in areas with these high barriers to entry.

Most of our stores compete with other well-managed and well-located competitors and we are subject to general economic conditions, particularly those that affect the spending habits of consumers and moving trends. Because we operate in competitive markets, often where self storage consumers have multiple stores from which to choose, such competition has affected and is likely to continue to affect our store results. We experience seasonal fluctuations in occupancy levels as well, with occupancy levels generally higher in the summer months due to

increased moving activity. We believe that our centralized information networks, national telephone and online reservation system, the brand name “Global Self Storage,” and our economies of scale help enable us to meet such challenges effectively.

In seeking to maximize the performance of our stores, we employ our proprietary revenue rate management program which help us to analyze, adjust, and set our move-in and existing tenant rental rates on a real-time basis across our portfolio. Among other technologies, we employ internet data scraping of our local competitors’ move-in rental rates to help enable us to proactively respond and take advantage of changing market conditions across our store portfolio. Our operating results typically depend significantly on our ability to manage our storage units’ rental rates, to respond in a timely manner to prospective tenant inquiries, and to lease available storage units, and on the ability of our tenants to make required storage unit rental payments.

We have registered the trademark and developed the brand “Global Self Storage.” We have developed a corporate logo and have incorporated it on all of our on-site signage, advertising and other marketing materials. This branding process has included the creation and development of the www.GlobalSelfStorage.us website, whereby prospective customers can rent a storage unit or learn about the features of any of our self storage properties. We continue to develop the Global Self Storage internet presence through advertising and search engine optimization. We solicit tenant reviews for posting to the “Customer Reviews” section of our website and encourage others to view these reviews. We have found referrals of current tenants to be a reliable source of new tenants. Existing self storage customers may also pay their storage unit rent online through www.GlobalSelfStorage.us.

Attracting high quality, long-term tenants is a top priority for the Company and we strongly believe in tenant quality over tenant quantity. In our marketing efforts, we have seen success in our referral marketing program, through which our tenants may recommend Global Self Storage to their family, friends, and colleagues. We also believe our store managers’ attention to detail – maintaining security, cleanliness, and attentive customer service – is essential to attracting high quality tenants.

Tenant leases at all of our stores are generally “month-to-month” leases. We seek to deliver at least 30 days’ written notice of any rental rate change. Lease rates at each store may be set monthly, semi-annually, annually, or at any other interval on a case-by-case basis as determined in the discretion of management. Tenants may be assessed late, administrative, and/or other fees. To date, none of the Company’s stores have experienced any material delinquencies.

Each of our stores features a rental and payment center kiosk available 24 hours a day, seven days a week, where prospective tenants can rent a unit and current tenants can pay their rent. All of our stores have on-site property managers who are committed to delivering the finest customer service. We utilize a customer call center to handle telephone inquiries from current and prospective tenants whenever our store managers are not available. They can respond to questions about our properties and storage features, and book reservations. We seek to deliver convenience and high quality customer service to our tenants, as well as maintain clean and secure stores at all times.

Please refer to Item 7 herein for further discussion of, among other things, competitive business conditions, the Company’s competitive position in the self storage industry, methods of competition, and the effect of existing or probable government regulations on the Company’s business.

Our Acquisition Strategy

General

In our store acquisition strategy, we will seek to continue to focus on secondary and tertiary cities in the Mid-West, Northeast and Mid-Atlantic parts of the country where we believe there is relatively less self storage space per capita available, generally resulting in greater demand for available self storage square feet; where new self storage development and permitting through the local planning and zoning boards is typically more difficult to secure thus creating barriers to entry for new self storage competition; and where local new supply through new development is generally less prevalent.

We continue to review available acquisition opportunities with the awareness that changes in interest rates may impact our ability to obtain favorable rates for financing acquisitions. We will seek to continue to employ our strict acquisition underwriting standards and remain a disciplined buyer and only execute acquisitions where we believe that our management techniques and innovations can strengthen our portfolio and increase stockholder value. For future acquisitions, the Company may employ various financing and capital raising alternatives, including, but not limited to, debt and/or equity offerings, credit facilities, mortgage financing, and joint ventures with third parties.

We conduct or obtain environmental assessments in connection with the acquisition or redevelopment of additional stores. Whenever the environmental assessment for one of our stores indicates that a store is impacted by soil or groundwater contamination from prior owners/operators or other sources, we will work with environmental consultants and where appropriate, state governmental agencies, to ensure that the store is cleaned up, that no cleanup is necessary because the low level of contamination poses no significant risk to public health or the environment, or that the responsibility for cleanup rests with a third party.

Our Financing Strategy

Our financing strategy is to seek to minimize the cost of our capital to maximize the returns generated for our stockholders. For future acquisitions, the Company may employ various financing and capital raising alternatives including, but not limited to, debt and/or equity offerings, credit facilities, mortgage financing, and joint ventures with third parties. For a history of our financing transactions, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Our Third-Party Management Platform

On October 23, 2019, we signed our first self storage client under our third-party management platform. As of December 31, 2025, the property, which was previously rebranded as “Global Self Storage,” had 137,318-leasable square feet and was comprised of 619 climate-controlled and non-climate-controlled units located in Edmond, Oklahoma.

We may pursue third-party management opportunities of properties owned by certain affiliates or joint venture partners for a fee, and utilize such relationships with third-party owners as a source for future acquisitions and investment opportunities.

Regulation

General

Generally, self storage properties are subject to various laws, ordinances and regulations, including those relating to lien sale rights and procedures, public accommodations, insurance, and the environment. Changes in any of these laws, ordinances or regulations could increase the potential liability existing or created by tenants or others on our properties. Laws, ordinances, or regulations affecting development, construction, operation, upkeep, safety and taxation requirements may result in significant unanticipated expenditures, loss of self storage stores or other impairments to operations, which would adversely affect our cash flows from operating activities.

Under the Americans with Disabilities Act of 1990 (the “ADA”), all places of public accommodation are required to meet certain federal requirements related to access and use by disabled persons. For additional information on the ADA, see “Item 1A. Risk Factors—Risks Related to Our Business—Costs associated with complying with the ADA may result in unanticipated expenses.”

Insurance activities are subject to state insurance laws and regulations as determined by the particular insurance commissioner for each state in accordance with the McCarran-Ferguson Act, as well as subject to the Gramm-Leach-Bliley Act and the privacy regulations promulgated by the Federal Trade Commission pursuant thereto.

Under the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended (“CERCLA”), and comparable state laws, we may be required to investigate and remediate regulated hazardous materials at one or more of our properties. For additional information on environmental matters and regulation, see “Item 1A. Risk Factors—Risks Related to Our Business—Extensive environmental regulation to which we are subject creates uncertainty regarding future environmental expenditures and liabilities.”

Property management activities are often subject to state real estate brokerage laws and regulations as determined by the particular real estate commission for each state.

REIT Qualification

We have elected and we believe that we have qualified to be taxed as a REIT under the Code, commencing with our taxable year ended on December 31, 2013. We generally will not be subject to U.S. federal income tax on our net taxable income to the extent that we distribute annually all of our net taxable income to our stockholders and maintain our qualification as a REIT. We believe that we have been organized and have operated in conformity with the requirements for qualification and taxation as a REIT under the Code, and we expect that our intended manner of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT. To qualify, and maintain our qualification, as a REIT, we must meet on a continuing basis, through our organization and actual investment and operating results, various requirements under the Code relating to, among other things, the sources of our gross income, the composition and values of our assets, our distribution levels and the diversity of ownership of our shares. If we fail to qualify as a REIT in any taxable year and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal income tax at regular corporate rates and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year during which we failed to qualify as a REIT. Even if we qualify for taxation as a REIT, we still may be subject to some U.S. federal, state and local taxes on our income or assets. In addition, subject to maintaining our qualification as a REIT, a portion of our business is conducted through, and a portion of our income is earned by, one or more taxable REIT subsidiaries (“TRSs”), which are subject to U.S. federal corporate income tax at regular rates. Distributions paid by us generally will not be eligible for taxation at the preferential U.S. federal income tax rates that currently apply to certain distributions received by individuals from taxable corporations, unless such distributions are attributable to dividends received by us from a TRS.

Competition

We compete with many other entities engaged in real estate investment activities for customers and acquisitions of self storage properties and other assets, including national, regional, and local owners, operators, and developers of self storage properties. We compete based on a number of factors including location, rental rates, security, suitability of the property’s design to prospective tenants’ needs, and the manner in which the property is operated and marketed. We believe that the primary competition for potential customers comes from other self storage properties within a three to five mile radius from our stores. We have positioned our properties within their respective markets as high-quality operations that emphasize tenant convenience, security, and professionalism.

We also may compete with numerous other potential buyers when pursuing a possible property for acquisition, which can increase the potential cost of a project. These competing bidders also may possess greater resources than us and therefore be in a better position to acquire a property.

Our primary national competitors in many of our markets for both tenants and acquisition opportunities include local and regional operators, institutional investors, private equity funds, as well as the other public self storage REITs. These entities also seek financing through similar channels to the Company. Therefore, we will continue to compete for investors in a market where funds for real estate investment may decrease.

Human Capital

We seek to create a work environment that values each employee’s talents and contributions. Our success relies on the general professionalism of our property managers and staff, which are contributing factors to our ability to successfully secure rentals, retain tenants and maintain clean and secure self storage properties. We seek to increase employee retention and well-being and our employees enjoy an attractive benefit package that includes medical, dental, vision, life insurance, 401(k) with matching employer contribution, cash bonuses, and long-term equity compensation. We offer competitive health benefits and encourage our employees to participate in employee health

and wellness programs. We also offer individualized counseling to our employees to assist them with their journeys towards better health.

In order to attract and retain top talent, we offer training and development opportunities for our employees. In 2025, this included anti-harassment training, cybersecurity training, and store manager training. We value the safety of our employees and provide regular training for our employees to increase safety at our properties.

Sustainability

We are focused on building our Company for the long-term to generate sustainable growth. To that end, we have established a cross-functional Sustainability committee (the "Sustainability Committee"), comprised of management, responsible for establishing our sustainability priorities and objectives. Management regularly evaluates sustainability risks faced by our real estate portfolio and believe the low obsolescence, geographic diversification, and low emissions of our portfolio help to mitigate those risks. Our Sustainability Committee reports annually to our board of directors on the status of our sustainability program, our progress against the goals we have set, and provides updates on the various initiatives we have undertaken to improve our sustainability.

A key area of focus from a sustainability perspective is minimizing the impact we make on the environment. Self storage remains a low-environmental impact business as it consumes less energy and water while emitting fewer greenhouse gases than other real estate property types. We continue to look for ways to further reduce our low impact through a variety of initiatives including solar panel installations, HVAC upgrades, high-efficiency LED lighting retrofits, energy management systems, and paper reduction through our online rental platform. In 2025, we continued to explore the installation of solar panels at our properties, which we expect would reduce energy consumption and costs at such locations.

Climate Change and Environmental Stewardship

We are committed to managing climate-related risks and opportunities in relation to our business. This commitment is a key component of our recognition that we must operate in a responsible and sustainable manner that aligns with our long-term corporate strategy and promotes our best interests along with those of our stakeholders, including our tenants, investors, employees, and the communities in which we operate.

Our Sustainability Committee guides our commitment to sustainability and has primary responsibility for climate-related activities. Our Sustainability Committee reports annually to our board of directors, which oversees all of our sustainability initiatives.

We consider potential environmental impacts—both positive and negative—into our decision making across the business. The following features of our properties reflect our commitment to responsible environmental stewardship:

•

Low environmental impact. Our properties have an inherently light environmental footprint that we further reduce through environmentally friendly capital initiatives.

•

Low obsolescence. Our properties are expected to retain functional and physical usefulness over many decades. This contrasts with other real estate types that require frequent reinvestment (i.e., capital expenditures) to stay current with tenant preference, remain competitive with newer competition, offset heavier wear-and-tear by users, and maintain structural operating efficiency.

•

High structural resilience. We operate our properties to avoid deferred maintenance, which may mitigate risks from rising water levels, changing temperatures, and natural disasters.

Item 1A. Risk Factors.

Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider the following risk factors, together with the other information contained in this annual report. Any of these risks described could materially adversely affect our business, financial condition, liquidity, results of operations, tax status or ability to make distributions to our stockholders. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business operations. If this were to happen, the price of our securities could decline significantly, and you could lose a part or all of your investment.

Risks Related to our Self Storage Properties and our Business

Adverse economic or other conditions in the markets in which we do business and more broadly could negatively affect our occupancy levels and rental rates and therefore our operating results.

Our operating results are dependent upon our ability to achieve optimal occupancy levels and rental rates at our self storage properties. Adverse economic or other conditions, such as during a government shutdown, in the markets in which we do business, may lower our occupancy levels and limit our ability to maintain or increase rents or require us to offer rental discounts. No single customer represents a significant concentration of our revenues. The following adverse developments, among others, in the markets in which we do business may adversely affect the operating performance of our properties:

•

perceptions by prospective tenants of the safety, convenience, and attractiveness of our self storage properties and the areas in which they are located;

•

industry slowdowns, relocation of businesses and changing demographics may adversely impact the markets in which we invest and in which our self storage properties operate;

•

periods of economic slowdown or recession, rising interest rates, or declining demand for self storage or the public perception that any of these events may occur could result in a general decline in rental rates or new rentals or an increase in tenant defaults; and

•

actual or perceived oversupply or declining demand for self storage in a particular area.

Our operations may be affected by general economic, political and market conditions.

Our operations may be affected by global and national economic, political and market conditions generally. Any of the following events could result in substantial impact to our business, financial condition, results of operations and cash flows:

•

changes in global, national, regional or local economic, demographic or capital market conditions;

•

a recession, slowdown or sustained downturn in the U.S. market, and to a lesser extent, the global economy (or any particular segment thereof);

•

overall weakening of, or disruptions in, the financial markets;

•

perceived or actual economic distress or failures of financial institutions;

•

increases in interest rates, inflationary pressures;

•

supply chain related disruptions, such as those caused by the COVID-19 pandemic;

•

geopolitical challenges and uncertainties (including wars and other forms of conflict, terrorist acts and security operations), such as the ongoing conflict between Iran and the United States, and Russia and Ukraine and the severe economic sanctions and export controls imposed by the U.S. and

other governments against Russia and Russian interests, and Iran and Iranian interests, and the ongoing conflict between Israel and Hamas; and

•

changes in government rules, regulations and fiscal policies, including increases in taxes, changes in zoning laws and increasing costs to comply with environmental laws.

All of these factors are beyond our control. Any negative changes in these factors could affect our business, financial condition, results of operations and cash flows.

If we are unable to promptly re-lease our units or if the rates upon such re-leasing are significantly lower than expected, then our business and results of operations would be adversely affected. Any delay in re-leasing units as vacancies arise would reduce our revenues and harm our operating results. In addition, lower than expected rental rates upon re-leasing could adversely affect our revenues and impede our growth.

Increases in taxes and regulatory compliance costs may reduce our income and adversely impact our cash flows.

Increases in income or other taxes generally are not passed through to tenants under leases and may reduce our net income, funds from operations (“FFO”), cash flows, financial condition, ability to pay or refinance our debt obligations, ability to make cash distributions to stockholders, and the trading price of our securities. Similarly, changes in laws increasing the potential liability for environmental conditions existing on properties or increasing the restrictions on discharges or other conditions may result in significant unanticipated expenditures, which could result in similar adverse effects.

Our property taxes could increase due to various reasons, including a reassessment, which could adversely impact our operating results and cash flow.

The value of our properties may be reassessed for property tax purposes by taxing authorities including as a result of the acquisition of new self storage properties. Accordingly, the amount of property taxes we pay in the future may increase substantially from what we have paid in the past. Increases in property or other taxes generally are not passed through to tenants under leases and may reduce our results of operations and cash flow, and could adversely affect our ability to pay any expected dividends to our stockholders.

Increases in operating costs may adversely affect our results of operation and cash flow.

Increases in operating costs, including insurance costs, labor costs, utilities, capital improvements, real estate assessments and other taxes and costs of compliance with REIT requirements and with other laws, regulations and governmental policies could adversely affect our results of operation and cash flow.

We depend upon our on-site personnel to maximize tenant satisfaction at each of our properties, and any difficulties we encounter in hiring, training, and maintaining skilled field personnel may harm our operating performance.

We depend upon our on-site personnel to maximize tenant satisfaction at each of our properties, and any difficulties we encounter in hiring, training and maintaining skilled field personnel may harm our operating performance. The general professionalism of a store’s managers and staff are contributing factors to a store’s ability to successfully secure rentals and retain tenants. If we are unable to successfully recruit, train and retain qualified field personnel, our quality of service could be adversely affected, which could lead to decreased occupancy levels and reduced operating performance.

We face competition from other self storage properties, which may adversely impact the markets in which we invest and in which our self storage properties operate.

Increased competition in the self storage business has led to both pricing and discount pressures. This increased competition could limit our ability to increase revenues in the markets in which we operate. While some markets may be able to absorb an increase in self storage properties due to superior demographics and density, other markets may not be able to absorb additional properties and may not perform as well.

Because our portfolio of properties consists of only self storage properties, we are subject to risks inherent in investments in a single industry. A decrease in the demand for self storage space would have a greater adverse effect on our rental revenues than it would if we owned a more diversified real estate portfolio. Demand for self storage space has been and could be adversely affected by ongoing weakness in the national, regional and local economies, changes in supply of, or demand for, similar or competing self storage properties in an area and the excess amount of self storage space in a particular market. To the extent that any of these conditions occur, they are likely to affect market rents for self storage space, which could cause a decrease in our rental revenue. Any such decrease could impair our operating results, ability to satisfy debt service obligations and ability to make cash distributions to our stockholders.

Further, currently we invest in a limited number of self storage properties. As a result, the potential effect on our financial condition, results of operations, and cash available for distribution to stockholders, resulting from poor performance at one or more of our self storage properties could be more pronounced than if we invested in a larger number of self storage properties.

We may not be successful in identifying and consummating suitable acquisitions, or integrating and operating acquired properties, which may adversely impact our growth.

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 brokered portfolios. Aggressive bidding practices by prospective acquirers have been commonplace and this competition also may be a challenge for our growth strategy and potentially result in our paying higher prices for acquisitions including paying consideration for certain properties that may exceed the value of such properties. Should we pay higher prices for self storage properties or other assets, our potential profitability may be reduced. Also, when we acquire any 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 growth 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 inability to achieve satisfactory completion of due diligence investigations and other customary closing conditions;

•

spending more than the time and amounts budgeted to make necessary improvements or renovations to acquired properties;

•

the inability to build a captive pipeline of target properties that meet our rigorous underwriting standards;

•

the inability to accurately estimate occupancy levels, rental rates, operating costs or costs of improvements to bring an acquired property up to the standards established for our intended market position; and

•

encountering delays in the selection, acquisition, or redevelopment of self storage properties which could adversely affect returns to stockholders and stockholders could suffer delays in the distribution of cash dividends attributable to any such properties.

We may not be able to develop a captive pipeline of acquisition targets without the use of non-refundable deposits.

We may be required to use non-refundable deposits to develop a captive pipeline of acquisition targets. If we are unable to raise the capital necessary to consummate such acquisitions we may be forced to abandon all or some of the acquisitions and forfeit any non-refundable deposits. If this occurs, it could adversely impact our operating results and our ability to pay any expected dividends to our stockholders.

We may acquire properties subject to liabilities which may adversely impact our operating results.

We may acquire properties subject to liabilities without any recourse, or with only limited recourse, with respect to known or unknown liabilities such as liabilities for clean-up of undisclosed environmental contamination, claims by persons dealing with the former owners of the properties and claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties. The costs associated with these liabilities may adversely impact our operating results.

Our investments in redevelopment projects may not yield anticipated returns which could adversely impact our economic performance.

In deciding whether to redevelop a particular property, we make certain assumptions regarding the expected future performance of that property. These assumptions are inherently uncertain, and, if they prove to be wrong, then we may be subject to certain risks including the following:

•

we may not complete redevelopment projects on schedule or within projected budgeted amounts;

•

we may underestimate the costs necessary to bring a property up to the standards established for its intended market position;

•

we may encounter delays or refusals in obtaining all necessary zoning, land use, building, occupancy and other required governmental permits and authorizations;

•

we may be unable to increase occupancy at a newly acquired property as quickly as expected or at all; and

•

we may be unable to obtain financing for these projects on favorable terms or at all.

The occurrence of such events could adversely affect the investment returns from these redevelopment projects and may adversely impact our economic performance.

Store ownership through joint ventures may limit our ability to act exclusively in our interest.

We may co-invest with third parties through joint ventures. In any such joint venture, we may not be in a position to exercise sole decision-making authority regarding the stores owned through joint ventures. Investments in joint ventures may, under certain circumstances, involve risks not present when a third party is not involved, including the possibility that joint venture partners might become bankrupt or fail to fund their share of required capital contributions. Joint venture partners may have business interests or goals that 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 also have the potential risk of impasse on strategic decisions, such as a sale, in cases where neither we nor the joint venture partner would have full control over the joint venture. In other circumstances, joint venture partners may have the ability without our agreement to make certain major decisions, including decisions about sales, capital expenditures, and/or financing. Any disputes that may arise between us and our joint venture partners could result in litigation or arbitration that could increase our expenses and distract our officers and/or directors from focusing their time and effort on our business. In addition, we might in certain circumstances be liable for the actions of our joint venture partners, and the activities of a joint venture could adversely affect our ability to qualify as a REIT, even though we do not control the joint venture.

Our performance is subject to risks associated with the real estate industry.

An investment in us is closely linked to the performance of the real estate markets in which we own self storage properties and subject to the risks associated with the direct ownership of real estate, including fluctuations in interest rates, inflation or deflation; declines in the value of real estate; and competition from other real estate investors with significant capital. Prevailing economic conditions affecting the real estate industry may adversely affect our business, financial condition and results of operations.

Illiquidity of real estate investments could significantly impede our ability to respond to adverse changes in the performance of our properties.

We may be unable to promptly sell one or more properties in response to changing economic, financial and investment conditions. 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 may be required to expend funds to correct defects or to make improvements before a property can be sold. We cannot give assurances that we will have funds available to correct those defects or to make those improvements. In acquiring a property, we may agree to transfer restrictions that materially restrict us from selling 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 transfer restrictions may impede our ability to sell a property even if we deem it necessary or appropriate. We may also have joint venture investments in certain of our properties and, consequently, our ability to control decisions relating to such properties may be limited.

Any negative perceptions of the self storage industry generally may result in a decline in our stock price.

To the extent that the investing public has a negative perception of the self storage industry, the value of our securities may be negatively impacted.

Costs associated with complying with various federal, state and local laws, regulations and governmental policies including the ADA may result in unanticipated expenses.

Our self storage properties also are subject to risks related to changes in, and changes in enforcement of, federal, state and local laws, regulations and governmental policies, including fire and safety requirements, health, zoning and tax laws, governmental fiscal policies and the ADA. Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by community developers may restrict our use of our properties and may require us to obtain approval from local officials or community standards organizations at any time with respect to our properties, including prior to acquiring a property or when undertaking renovations of any of our existing properties. Further, compliance with the ADA and other regulations may require us to make unanticipated expenditures that could significantly reduce cash available for distribution to stockholders. A failure to comply with the ADA or similar state laws could lead to government imposed fines on us and/or litigation, which could also involve an award of damages to individuals affected by the noncompliance. Such noncompliance also could result in an order to correct any noncomplying feature, which could result in substantial capital expenditures.

Extensive environmental regulation to which we are subject creates uncertainty regarding future environmental expenditures and liabilities.

Under environmental regulations such as CERCLA, owners and operators of real estate may be liable for the costs of investigating and remediating certain hazardous substances or other regulated materials on or in such property. Such laws often impose liability, without regard to knowledge or fault, for removal or remediation of hazardous substances or other regulated materials upon owners and operators of contaminated property, even after they no longer own or operate the property. Moreover, the past or present owner or operator of a property from which a release emanates could be liable for any personal injuries or property damages that may result from such releases, as well as any damages to natural resources that may arise from such releases. The presence of such substances or materials, or the failure to properly remediate such substances, may adversely affect the owner’s or operator’s ability to lease, sell or rent such property or to borrow using such property as collateral.

Climate change and regulatory and other efforts to address climate change could adversely affect our business.

We face a number of risks associated with climate change including both transition and physical risks. The transition risks that could impact the Company include those risks related to the impact of U.S. and foreign climate- and sustainability-related legislation and regulation, as well as risks arising from climate-related business trends. Moreover, we are subject to risks stemming from the physical impacts of climate change. In particular, significant physical effects of climate change including extreme weather events can also have an adverse impact on our properties. Additionally, both transition and physical risks associated with climate change could result in increased operating costs for our properties. As the effects of climate change increase, we expect the frequency and impact of weather and

climate related events and conditions to increase as well. These risks may adversely impact our business, financial condition and results of operations.

New climate change-related regulations or interpretations of existing laws may result in enhanced disclosure obligations that could negatively affect us and materially increase our regulatory burden. Increased regulations generally increase the costs to us, and those higher costs may continue to increase if new laws require additional resources, including spending more time, hiring additional personnel or investing in new technologies.

We also face business trend-related climate risks. Certain investors are increasingly taking into account environmental, social, and governance ("ESG") factors, including climate risks, in determining whether to invest in companies. Additionally, our reputation and investor relationships could be damaged as a result of our involvement with activities perceived to be causing or exacerbating climate change, as well as any decisions we make to continue to conduct or change our activities in response to considerations relating to climate change. Recently, the United States federal government and certain states have enacted or proposed “anti-ESG” executive orders, policies or legislation and certain investors, customers and governmental authorities may oppose ESG initiatives. These increasingly divergent views on ESG matters increase the risk that any action or lack of action taken by the Company with respect to ESG matters may be perceived negatively by at least some investors and customers and adversely impact our reputation and business.

We may become subject to litigation or threatened litigation or other claims that may divert management’s time and attention, require us to pay damages and expenses or restrict the operation of our business.

We may become subject to disputes with commercial parties with whom we maintain relationships or other parties with whom we do business. Any such dispute could result in litigation between us and the other parties. Whether or not any dispute actually proceeds to litigation, we may be required to devote significant management time and attention as well as associated costs of legal and other advisors to its successful resolution (through litigation, settlement or otherwise), which would detract from our management’s ability to focus on our business. Any such resolution could involve the payment of damages or expenses by us, which may be significant. In addition, any such resolution could involve our agreement with terms that restrict the operation of our business.

From time to time we may be required to resolve tenant claims and litigation and employment-related claims and litigation by corporate level and field personnel which could result in substantial liabilities to us. We also could be sued for personal injuries and/or property damage occurring at our properties. The liability insurance we maintain may not cover all costs and expenses arising from such lawsuits.

Uninsured losses or losses in excess of our insurance coverage could adversely affect our financial condition and cash flow.

We maintain comprehensive liability, fire, flood, earthquake, wind, extended coverage and rental loss insurance (as deemed necessary or as required by our lenders, if any) with respect to our properties. Certain types of losses, however, may be either uninsurable or not economically insurable, such as losses due to earthquakes, hurricanes, tornadoes, riots, acts of war or terrorism. Should an uninsured loss occur, we could lose both our investment in and anticipated profits and cash flow from a property. In addition, if any such loss is insured, we may be required to pay significant amounts on any claim for recovery of such a loss prior to our insurer being obligated to reimburse us for the loss, or the amount of the loss may exceed our coverage for the loss.

To the extent that we invest in publicly traded REITs, our performance may be subject to the risks of investment in such securities.

The value of our investments in REITs may fluctuate, sometimes rapidly and unpredictably. Because REITs concentrate their assets in the real estate industry, the performance of REITs is closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from economic, legal, cultural or technological developments, rising interest rates, and rising capitalization rates. REIT prices also may drop because of the failure of borrowers to pay their loans and poor management. In addition, there are specific risks associated with particular sectors of real estate investments such as self storage, retail, office, hotel, healthcare, and multi-family properties. Many REITs utilize leverage, which increases investment risk and could

adversely affect a REIT’s operations and market value in periods of rising interest rates as well as risks normally associated with debt financing. In addition, a REIT’s failure to qualify as a REIT under the Code, or failure to maintain exemption from registration under the Investment Company Act could adversely affect our operations and our qualification as a REIT under the Code. The failure of these investments to perform as expected may have a significant effect on our performance and our ability to make distributions to stockholders.

We may be unable to make distributions in the future, maintain our current level of distributions or increase distributions over time.

There are many factors that can affect the availability and timing of cash distributions to stockholders and the determination to make distributions will fall within the discretion of our board of directors. Our board of directors’ decisions to pay distributions will depend on many factors, such as our historical and projected results of operations, financial condition, cash flows and liquidity, maintenance of our REIT qualification and other tax considerations, capital expenditure and other expense obligations, debt covenants, contractual prohibitions or other limitations and applicable law and such other matters as our board of directors may deem relevant from time to time. Actual cash available for distributions may vary substantially from estimates. We may not have sufficient available cash from operations to make a distribution required to qualify for or maintain our REIT status. We may be required to borrow or make distributions that would constitute a return of capital which may reduce the amount of capital we invest in self storage properties. We cannot assure stockholders that we will be able to make distributions in the future, be able to maintain our current level of distributions or that our distributions will increase over time, and our inability to make distributions, or to make distributions at expected levels, could result in a decrease in the market price of our common stock.

We rely on information technology networks and systems, including the internet, to process, transmit and store electronic information, and to manage or support a variety of business processes, including, but not limited to, financial transactions and records, personally identifiable information, and tenant and lease data. In many cases, we rely significantly on third-party vendors to retain data, process transactions, and provide information technology and other system services. Our networks and operations could be disrupted, and sensitive data could be compromised, by physical or electronic security breaches, targeted against us, our vendors or other organizations, including financial markets or institutions, including by way of or through cyber-attacks or cyber-intrusions over the internet, malware, computer viruses, attachments to e-mails, phishing, employee theft or misuse, or inadequate security controls. We rely on third-party vendors and commercially available systems, software, tools and monitoring to provide security for processing, transmission and storage of confidential tenant and other sensitive information. Although we make efforts to protect the security and integrity of our networks and systems, there can be no assurance that these efforts and measures will be effective or that attempted security breaches or disruptions would not be successful, as such attacks and breaches may be difficult to detect (or not detected at all) and are becoming more sophisticated. In such event, we may experience business interruptions or shutdowns; data loss, ransom, misappropriation, or corruption; theft or misuse of confidential or proprietary information; or litigation and investigation by tenants, governmental or regulatory agencies, or other third parties. Such events could also have other adverse impacts on us, including, but not limited to, regulatory penalties, breaches of debt covenants or other contractual or REIT compliance obligations, late or misstated financial reports, and significant diversion of management attention and resources. As a result, such events could have a material adverse effect on our financial condition, results of operations and cash flows and harm our business reputation.

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

Personal privacy has become a significant issue in the jurisdictions in which we operate. Many jurisdictions in which we operate have imposed restrictions and requirements on the use of personal information by those collecting such information. Changes to the laws or regulations affecting privacy, if applicable to our business, could impose additional costs and liability on us and could limit our use and disclosure of such information.

Major public health issues and related disruptions in the U.S. and global economy and financial markets could adversely impact or disrupt our financial condition and results of operations.

In recent years, the outbreaks of a number of diseases, including COVID-19, avian influenza, H1N1, and other viruses, have increased the risk of a pandemic or major public health issues.

We believe that our level of business activity and the profitability of our business, as well as the values of, and the cash flows from, the assets we own could in the future be impacted by a pandemic or other major public health issue. While we have taken preventive measures and other precautions, no predictions of specific scenarios can be made with certainty and such measures may not adequately predict the impact on our business from such events.

The extent of the impact of a pandemic and any other pandemic or major health issue on us will depend on many factors, including the duration and scope of the public health emergency, the actions taken by governmental authorities to contain such pandemics or public health issues and their financial and economic impact, the implementation of travel advisories and restrictions, the efficacy and availability of vaccines, the disparities in vaccination rates and vaccine hesitancy, the rise of new variants and the severity of such variants, the impact of the public health emergency on overall supply and demand, goods and services, consumer confidence and levels of economic activity and the extent of its disruption to global, regional, and local supply chains and economic markets, all of which are uncertain and difficult to assess. Moreover, many risk factors set forth in this annual report on Form 10-K should be interpreted as heightened risks as a result of the impact of a pandemic or other major public health issue.

Our use of or failure to adopt advancements in information technology, such as artificial intelligence, may hinder or prevent us from achieving strategic objectives or otherwise harm our business.

Our use of or inability to safely and effectively adopt and deliver new technological capabilities and enhancements in line with strategic objectives, including artificial intelligence and machine learning, may put us at a competitive disadvantage; cause us to miss opportunities to innovate, achieve efficiencies, or improve the customer experience; or adversely impact our business, reputation, results of operations, and financial condition.

Legislative and regulatory activity related to information technology, including related to privacy, may also result in new laws that are applicable to us and that may hinder our business, including by restricting our use of customer data or otherwise regulating the use of algorithms and automated processing in ways that could materially affect our business or lead to significant increases in the cost of compliance.

Risks Related to Our Organization and Structure

The ability of our board of directors to revoke our REIT election without stockholder approval may cause adverse consequences to our stockholders.

Our board of directors may revoke or otherwise terminate our REIT election without the approval of stockholders if it determines that it is no longer in our best interests to continue to qualify as a REIT. If we cease to qualify as a REIT, we would become subject to U.S. federal income tax on our taxable income and would no longer be required to distribute most of our net taxable income to stockholders, which may have adverse consequences on the total return to our stockholders.

Our business could be harmed if key personnel with business experience in the self storage industry terminate their employment with us.

Our officers have experience in the self storage industry and our success will depend, to a significant extent, on their services. There is no guarantee that any of them will remain employed with us. We do not generally maintain key person life insurance. The loss of services of one or more members of our senior management could harm our business.

There may be conflicts of interest resulting from the relationships among us, our affiliates, and other related parties.

The outside business interests of our officers may divert their time and attention away from us, and may result in a potential conflict with respect to the allocation of business opportunities, which could harm our business. Our board of directors has adopted policies and procedures designed to mitigate these conflicts of interest, such as allocation procedures for determining the appropriate allocation of such business opportunities. Specifically, if any of our officers or directors who also serves as an officer, director, or advisor of our affiliates becomes aware of a potential transaction related primarily to the self storage business that may represent a corporate opportunity for us and one or more of our affiliates, such officer or director has no duty to present that opportunity to such affiliates and we will have the sole right to pursue the transaction if our board of directors so determines. Notwithstanding the foregoing, our officers or directors are encouraged to notify our affiliates of such an opportunity.

Certain provisions of Maryland law could inhibit changes in control of our company.

Certain “business combination” and “control share acquisition” provisions of the Maryland General Corporation Law (“MGCL”), may have the effect of deterring a third party from making a proposal to acquire us or of impeding a change in control under circumstances that otherwise could provide the holders of our common stock with the opportunity to realize a premium over the then-prevailing market price of our common stock. Pursuant to the MGCL, our board of directors has by resolution exempted business combinations between us and any other person. Our bylaws contain a provision exempting from the control share acquisition statute any and all acquisitions by any person of shares of our stock. However, there can be no assurance that these exemptions will not be amended or eliminated at any time in the future. Our charter and bylaws and Maryland law also contain other provisions that may delay, defer or prevent a transaction or a change of control that might involve a premium price for our common stock or that our stockholders otherwise believe to be in their best interest.

Our rights and the rights of our stockholders to take action against our directors and officers are limited, which could limit your recourse in the event of actions not in your best interest.

Our charter limits the liability of our present and former directors and officers to us and our stockholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, our present and former directors and officers will not have any liability to us or our stockholders for money damages other than liability resulting from:

•

actual receipt of an improper benefit or profit in money, property or services; or

•

active and deliberate dishonesty by the director or officer that was established by a final judgment and is material to the cause of action.

Our charter authorizes us to indemnify our present and former directors and officers for actions taken by them in those capacities to the maximum extent permitted by Maryland law. Our bylaws require us to indemnify each present and former director or officer, to the maximum extent permitted by Maryland law, in connection with any proceeding to which he or she is made, or threatened to be made, a party to or witness in by reason of his or her service to us as a director or officer or in certain other capacities. In addition, we may be obligated to pay or reimburse the expenses incurred by our present and former directors and officers without requiring a preliminary determination of their ultimate entitlement to indemnification. As a result, we and our stockholders may have more limited rights against our present and former directors and officers than might otherwise exist absent the current provisions in our charter and bylaws or that might exist with other companies, which could limit your recourse in the event of actions not in your best interest.

Our charter contains provisions that make removal of our directors difficult, which could make it difficult for our stockholders to effect changes to our management.

Our charter provides that, subject to the rights of holders of one or more classes or series of preferred shares, a director may be removed with cause, by the affirmative vote of at least two-thirds of the votes entitled to be cast generally in the election of directors. Vacancies on our board of directors generally may be filled only by a majority of the remaining directors in office, even if less than a quorum. These requirements make it more difficult to change our management by removing and replacing directors and may prevent a change in our control that is in the best interests of our stockholders.

We may change our investment and financing strategies and enter into new lines of business without stockholder consent, which may subject us to different risks.

We may change our investment and financing strategies and enter into new lines of business at any time without the consent of our stockholders, which could result in our making investments and engaging in business activities that are different from, and possibly riskier than, the investments and businesses described in this document. A change in our investment strategy or our entry into new lines of business may impact our ability to qualify or remain qualified as a REIT, or increase our exposure to other risks or real estate market fluctuations.

If other self storage companies convert to a REIT structure or if tax laws change, we may no longer have an advantage in competing for potential acquisitions.

Because we are structured as a REIT, we are a more attractive acquirer of properties to tax-motivated sellers than our competitors that are not structured as REITs. However, if other self storage companies restructure their holdings to become REITs, this competitive advantage will disappear. In addition, new legislation may be enacted or new interpretations of existing legislation may be issued by the Internal Revenue Service (the “IRS”), or the U.S. Treasury Department that could affect the attractiveness of the REIT structure so that it may no longer assist us in competing for acquisitions.

Our board of directors has the power to issue additional shares of our stock in a manner that may not be in the best interest of our stockholders.

Our charter authorizes our board of directors to issue additional authorized but unissued shares of common stock or preferred stock and to increase the aggregate number of authorized shares or the number of shares of any class or series without stockholder approval. In addition, our board of directors may classify or reclassify any unissued shares of common stock or preferred stock and set the preferences, rights and other terms of the classified or reclassified shares. Our board of directors could issue additional shares of our common stock or establish a series of preferred stock that could have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price for our securities or otherwise not be in the best interests of our stockholders.

Restrictions on ownership and transfer of our shares may restrict change of control or business combination opportunities in which our stockholders might receive a premium for their shares.

In order for us to qualify as a REIT for each taxable year after our taxable year ended December 31, 2013, no more than 50% in value of our outstanding shares may be owned, directly or constructively, by five or fewer individuals during the last half of any calendar year, and at least 100 persons must beneficially own our shares during at least 335 days of a taxable year of 12 months, or during a proportionate portion of a shorter taxable year. “Individuals” for this purpose include natural persons, private foundations, some employee benefit plans and trusts, and some charitable trusts. Our charter contains, among other things, such customary provisions related to our current operation as a REIT and such other provisions that are consistent with the corporate governance profile of our public peers, including certain customary ownership limitations that prohibit, among other limitations, any person from beneficially or constructively owning more than 9.8% in value or in number of shares, whichever is more restrictive, of the outstanding shares of our common stock or all classes and series of our capital stock. These ownership limits and the other restrictions on ownership and transfer of our shares in our charter could have the effect of discouraging a takeover or other transaction in which holders of our common stock might receive a premium for their shares over the then prevailing market price or which holders might believe to be otherwise in their best interests.

Risks Related to Our Debt Financings

Disruptions in the financial markets could affect our ability to obtain debt financing on reasonable terms or at all and have other adverse effects.

Uncertainty in the credit markets may negatively impact our ability to access additional debt financing or to refinance existing debt maturities on favorable terms (or at all), which may negatively affect our ability to make acquisitions. A downturn in the credit markets may cause us to seek alternative sources of potentially less attractive financing, and may require us to adjust our business plans accordingly. In addition, these factors may make it more

difficult for us to sell properties or may adversely affect the price we receive for properties that we do sell, as prospective buyers may experience increased costs of debt financing or difficulties in obtaining debt financing.

We depend on external sources of financing to acquire properties, to satisfy our debt obligations and to make distributions to our stockholders required to maintain our qualification as a REIT, and these sources of financing may not be available on favorable terms, or at all. Our access to external sources of financing depends on a number of factors, including the market’s perception of our growth potential and our current and potential future earnings and our ability to continue to qualify as a REIT for U.S. federal income tax purposes. If we are unable to obtain external sources of financing, we may not be able to acquire properties when strategic opportunities exist, satisfy our debt obligations or make cash distributions to our stockholders that would permit us to qualify as a REIT or avoid paying U.S. federal income tax on all of our net taxable income.

The terms and covenants relating to our indebtedness could adversely impact our economic performance.

The Second Amended Credit Facility Loan Documents and the Term Loan Documents contain (and any new or amended loan and/or facility we may enter into from time to time will likely contain) customary affirmative and negative covenants, including financial covenants that, among other things, require us to comply with a minimum net worth (as defined in the Second Amended Credit Facility Loan Documents and Term Loan Documents) of at least the outstanding principal balance of the term loan and a minimum liquidity standard of at least 10% of the outstanding principal balance of the term loan (as defined in the Second Amended Credit Facility Loan Documents and Term Loan Documents). In the event that we fail to satisfy our covenants, we would be in default under the Second Amended Credit Facility Loan Documents and the Term Loan Documents and may be required to repay such debt with capital from other sources. Under such circumstances, other sources of debt or equity capital may not be available to us, or may be available only on unattractive terms. Moreover, the presence of such covenants could cause us to operate our business with a view toward compliance with such covenants, which might not produce optimal returns for stockholders.

Risks Related to Our Qualification as a REIT

We have elected, and believe that we have been qualified, to be taxed as a REIT commencing with the taxable year ended December 31, 2013. Qualification for treatment as a REIT involves the application of highly technical and extremely complex Code provisions for which there are only limited judicial and administrative interpretations. The determination of various factual matters and circumstances not entirely within our control may affect our ability to qualify for REIT treatment. To qualify as a REIT, we must meet, on an ongoing basis through actual operating results, various tests regarding the nature and diversification of our assets and our income, the ownership of our outstanding shares and the amount of our distributions. Our compliance with the REIT income and quarterly asset requirements also depends upon our ability to manage successfully the composition of our income and assets on an ongoing basis. Our ability to satisfy these asset tests depends upon an analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination, and for which we will not obtain independent appraisals. In addition, we have held and may continue to hold investments in other publicly traded REITs. If any such publicly traded REIT fails to qualify as a REIT with respect to any period during which we hold or have held shares of such REIT, or if our interests in these REITs are otherwise not treated as equity in a REIT for U.S. federal income tax purposes, our ability to satisfy the REIT requirements could be adversely affected. Moreover, new legislation, court decisions or administrative guidance may, in each case possibly with retroactive effect, make it more difficult or impossible for us to qualify as a REIT. Thus, while we believe that we have been organized and operated and intend to operate so that we will continue to qualify as a REIT, given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations and the possibility of future changes in our circumstances, no assurance can be given that we have qualified or will so qualify for any particular year. These considerations also might restrict the types of assets that we can acquire or services that we can provide in the future. We have not requested and do not plan to request a ruling from the IRS regarding our qualification as a REIT.

In order to qualify as a REIT, among other requirements, we must ensure that at least 75% of our gross income for each taxable year, excluding certain amounts, is derived from certain real property-related sources, and at least 95% of our gross income for each taxable year, excluding certain amounts, is derived from certain real property-related sources and passive income such as dividends and interest. For purposes of these rules, income from the rental of real property is generally treated as qualifying income, whereas service income is generally treated as nonqualifying income. Furthermore, for purposes of these rules, services provided to tenants at a property could cause all income from the property to be nonqualifying if the income from such services, or the costs of providing those services, exceed certain thresholds. We have provided and may continue to provide certain services to our tenants, such as access to insurance. We believe that these services have been provided in a manner that does not cause our rental income to fail to be treated as qualifying income for purposes of the REIT gross income tests. However, if the IRS were to successfully challenge our characterization of these services, our qualification as a REIT could be adversely impacted. In addition, where we have provided services that may generate nonqualifying income, we believe the income attributable to these services and the costs of providing these services are sufficiently small so as not to cause us to fail to satisfy the REIT gross income tests. However, there is limited guidance regarding what costs are taken into account for this purpose. If the IRS were to successfully assert that our income from these services or the costs of providing these services exceeded certain thresholds, we could fail to qualify as a REIT.

If we fail to qualify for treatment as a REIT at any time and do not qualify for certain statutory relief provisions, we would be required to pay U.S. federal income tax on our taxable income, and possibly could be required to borrow money or sell assets to pay that tax, thus substantially reducing the funds available for distribution for each year involved. Unless entitled to relief under specific statutory provisions, we would also be disqualified from treatment as a REIT for the four taxable years following the year during which we lost our qualification. In addition, all distributions to stockholders, including capital gain dividends, would be subject to tax as regular dividends to the extent of our earnings and profits.

Even if we qualify as a REIT, we may face other tax liabilities that reduce our cash flow.

Even though we believe that we currently qualify for U.S. federal income tax purposes as a REIT, we may face tax liabilities that will reduce our cash flow, including taxes on any undistributed income, state or local income and property and transfer taxes, including real property transfer taxes. In addition, we could, in certain circumstances, be required to pay an excise or penalty tax (which could be significant in amount) in order to utilize one or more relief provisions under the Code to maintain our qualification as a REIT. Any of these taxes would decrease operating cash flow to our stockholders. In addition, in order to meet the REIT qualification requirements, or to avert the imposition of a 100% tax that applies to certain gains derived by a REIT from dealer property or inventory, we hold some of our assets and provide certain services to our tenants through one or more TRSs, or other subsidiary corporations that will be subject to corporate-level income tax at regular corporate rates. Any TRSs or other taxable corporations in which we invest will be subject to U.S. federal, state and local corporate taxes.

Furthermore, if we acquire appreciated assets from a corporation that is or has been a subchapter C corporation in a transaction in which the adjusted tax basis of such assets in our hands is less than the fair market value of the assets, determined at the time we acquired such assets, and if we subsequently dispose of any such assets during the 5-year period following the acquisition of the assets from the C corporation, we will be subject to tax at the highest corporate tax rates on any gain from the disposition of such assets to the extent of the excess of the fair market value of the assets on the date that we acquired such assets over the basis of such assets on such date, which are referred to as built-in gains. Payment of these taxes generally could materially and adversely affect our income, cash flow, results of operations, financial condition, liquidity and prospects, and could adversely affect the value of our common stock and the ability to make distributions to stockholders.

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 the 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, the per share trading price of our common stock, 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 our financial condition, results of operations, cash flows and our ability to pay distributions on, and the per share trading price of, our common stock.

Failure to make required distributions would subject us to tax, which would reduce the operating cash flow available for distribution to stockholders.

Failure to make required distributions would subject us to tax, which would reduce the operating cash flow to our stockholders. In order to qualify as a REIT, we must distribute to our stockholders each calendar year at least 90% of our net taxable income (excluding net capital gain). To the extent that we satisfy the 90% distribution requirement, but distribute less than 100% of our net taxable income (including net capital gain), we would be subject to U.S. federal corporate income tax on our undistributed net taxable income. In addition, we will incur a 4% non-deductible excise tax on the amount, if any, by which our distributions in any calendar year are less than a minimum amount specified under U.S. federal income tax laws. Although we intend to distribute our net taxable income to our stockholders in a manner intended to satisfy the REIT 90% distribution requirement and to avoid the 4% non-deductible excise tax, it is possible that we, from time to time, may not have sufficient cash to distribute 100% of our net taxable income. There may be timing differences between our actual receipt of cash and the inclusion of items in our income for U.S. federal income tax purposes. Accordingly, there can be no assurance that we will be able to distribute net taxable income to stockholders in a manner that satisfies the REIT distribution requirements and avoids the 4% non-deductible excise tax.

Complying with the REIT requirements may cause us to forgo and/or liquidate otherwise attractive investments.

To qualify as a REIT for U.S. federal tax purposes, we must continually satisfy various requirements 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. Among other requirements, to qualify as a REIT, we must satisfy certain annual gross income tests and we must ensure that, at the end of each calendar quarter, at least 75% of the value of our total assets consists of cash, cash items, U.S. government securities and qualified real estate assets. The remainder of our investment in securities generally cannot include more than 10% of the outstanding voting securities of any one issuer (other than U.S. government securities, securities of corporations that are treated as TRSs and qualified real estate assets) or more than 10% of the total value of the outstanding securities of any one issuer (other than government securities, securities of corporations that are treated as TRSs and qualified real estate assets). In addition, in general, no more than 5% of the value of our assets can consist of the securities of any one issuer (other than U.S. government securities, securities of corporations that are treated as TRSs and qualified real estate assets), no more than 20% of the value of our total assets can be represented by securities of one or more TRSs and no more than 25% of the value of our assets can consist of debt instruments issued by publicly offered REITs that are not otherwise secured by real property. If we fail to comply with these asset requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences.

To meet these tests, we may be required to take or forgo taking actions that we would otherwise consider advantageous. For instance, in order to satisfy the gross income or asset tests applicable to REITs under the Code, we may be required to forgo investments that we otherwise would make. Furthermore, we may be required to liquidate from our portfolio otherwise attractive investments. In addition, we may be required to make distributions to stockholders at disadvantageous times or when we do not have funds readily available for distribution. These actions could reduce our income and amounts available for distribution to stockholders. Thus, compliance with the REIT requirements may hinder our investment performance.

We may be subject to a 100% tax on income from “prohibited transactions,” and this tax may limit our ability to sell assets or require us to restructure certain of our activities in order to avoid being subject to the tax.

We are subject to a 100% tax on any income from a prohibited transaction. “Prohibited transactions” generally include sales or other dispositions of property (other than property treated as foreclosure property under the Code) that is held as inventory or primarily for sale to customers in the ordinary course of a trade or business by a REIT, either directly or indirectly through certain pass-through subsidiaries. The characterization of an asset sale as a prohibited transaction depends on the particular facts and circumstances.

The 100% tax will not apply to gains from the sale of inventory that is held through a TRS or other taxable corporation, although such income will be subject to tax in the hands of the corporation at regular corporate income tax rates. We have sold items such as locks, boxes, and packing materials to tenants and third parties directly rather

than through a TRS, and as a result could be liable for this tax with respect to these sales. To the extent that we continue to sell such inventory items, other than through a TRS, we may be subject to this 100% tax.

Our TRSs will be subject to U.S. federal income tax and will be required to pay a 100% penalty tax on certain income or deductions if transactions with such TRSs are not conducted on arm’s length terms.

We conduct certain activities (such as selling packing supplies and locks and renting trucks or other moving equipment) through one or more TRSs.

A TRS is a corporation other than a REIT in which a REIT directly or indirectly holds stock, and that has made a joint election with such REIT to be treated as a TRS. If a TRS owns more than 35% of the total voting power or value of the outstanding securities of another corporation, such other corporation will also be treated as a TRS. Other than some activities relating to lodging and health care properties, a TRS may generally engage in any business, including the provision of customary or non-customary services to tenants of its parent REIT. A TRS is subject to U.S. federal income tax as a regular C corporation.

No more than 20% of the value of a REIT’s total assets may consist of stock or securities of one or more TRSs. This requirement limits the extent to which we can conduct our activities through TRSs. The values of some of our assets, including assets that we hold through TRSs, may not be subject to precise determination, and values are subject to change in the future. In addition, the Code imposes a 100% tax on certain transactions between a TRS and its parent REIT that are not conducted on an arm’s length basis. We intend to structure transactions with any TRS on terms that we believe are arm’s length to avoid incurring the 100% excise tax described above. There can be no assurances, however, that we will be able to avoid application of the 100% tax.

We may not have cash available to make distributions.

Our taxable income may exceed our cash flow for a year, which could necessitate our borrowing funds and/or subject us to tax, thus reducing the cash available for distribution to our stockholders. We intend to make cash distributions each year sufficient to satisfy REIT distribution requirements and to avoid liability for the REIT excise tax. There can be no assurance, however, that we will be able to do so. Our taxable income may substantially exceed our net income as determined based on GAAP, as well as our cash flow, because, for example, realized capital losses will be deducted in determining GAAP net income but may not be deductible in computing taxable income or because we acquired assets that generate taxable income in excess of economic income or in advance of the corresponding cash flow from the assets. Under the Tax Cuts and Jobs Act of 2017 (the “TCJA”), which was signed into law on December 22, 2017, we generally will be required to recognize certain amounts in income no later than the time such amounts are reflected on our financial statements. Also, in certain circumstances our ability to deduct interest expenses for U.S. federal income tax purposes may be limited by provisions of the TCJA. If the cash flow we generate in a particular year is less than our taxable income, we may be required to use cash reserves, incur short-term, or possibly long-term, debt or liquidate non-cash assets at rates or at times that are unfavorable in order to make the necessary distributions.

Our REIT qualification could be adversely affected by the REIT qualification of any REIT in which we hold an interest.

In connection with our conversion from a regulated investment company (a “RIC”) to a REIT, we disposed of the majority of our assets and acquired government securities and shares of publicly traded REITs. As a result, our qualification as a REIT has depended on the REIT qualification of the publicly traded REITs in which we have invested. Furthermore, we may continue to hold interests in publicly traded REITs, and as a result our REIT qualification may continue to depend on the REIT qualification of any publicly traded REITs in which we continue to hold an interest. We do not generally independently investigate the REIT qualification of such REITs, but rather generally rely on statements made by such REITs in their public filings. In the event that one or more of the publicly traded REITs in which we invested was not properly treated as a REIT for U.S. federal income tax purposes, or if our interests in these REITs were otherwise not treated as equity in a REIT for U.S. federal income tax purposes, it is possible that we may not have met certain of the REIT asset and income requirements, in which case we could have failed to qualify as a REIT. Similarly, if we hold an interest in a publicly traded REIT in the future that fails to qualify as a REIT, such failure could adversely impact our REIT qualification.

We could fail to qualify as a REIT if we have not distributed any earnings and profits attributable to a taxable year before we elected to be taxed as a REIT.

A corporation does not qualify as a REIT for a given taxable year if, as of the final day of the taxable year, the corporation has any undistributed earnings and profits that accumulated during a period that the corporation was not treated as a REIT. Because we were not treated as a REIT for our entire existence (such period prior to our election to be taxed as a REIT, the “Pre-REIT period”), it is possible that we could have undistributed earnings and profits from the Pre-REIT period, in which case we would be required to pay a deficiency dividend in order to comply with this requirement or could fail to qualify as a REIT. We believe that, since December 31, 2013, we have not had any earnings and profits accumulated from the Pre-REIT period because all such earnings and profits were distributed prior to December 31, 2013. In particular, prior to December 31, 2013, we believe that we qualified as a RIC for U.S. federal income tax purposes, and as a RIC, we distributed our earnings on an annual basis in order to avoid being subject to U.S. federal income tax on our undistributed earnings. However, if it is determined that we have accumulated earnings and profits from the Pre-REIT period, we could be required to pay a deficiency dividend to stockholders after the relevant determination in order to maintain our qualification as a REIT, or we could fail to qualify as a REIT.

We may not have satisfied requirements related to the ownership of our outstanding stock, which could cause us to fail to qualify as a REIT.

In order to qualify as a REIT, not more than 50% in value of our outstanding stock may be owned, directly or indirectly, through the application of certain attribution rules under the Code, by five or fewer individuals, as defined in the Code to include specified entities, during the last half of any taxable year other than the first taxable year during which we qualified as a REIT (the “5/50 Test”). Prior to October 20, 2017, our charter did not contain customary REIT ownership restrictions and therefore did not ensure that we satisfied the 5/50 Test. Effective as of October 20, 2017, our charter was revised to include, among other things, certain customary ownership limitations that prohibit, among other limitations, any person from beneficially or constructively owning more than 9.8% in value or in number of shares, whichever is more restrictive, of the outstanding share of our common stock or all classes and series of our capital stock. These provisions are intended to assist us in satisfying the 5/50 Test. With respect to the period between January 1, 2013 and October 20, 2017, we monitored purchases and transfers of shares of our common stock by regularly reviewing, among other things, ownership filings required by the federal securities laws to monitor the beneficial ownership of our shares in an attempt to ensure that we met the 5/50 Test. However, the attribution rules under the Code are broad, and we may not have had the information necessary to ascertain with certainty whether or not we satisfied the 5/50 Test during such period. As a result, no assurance can be provided that we satisfied the 5/50 Test during such period. If it were determined that we failed to satisfy the 5/50 Test, we could fail to qualify as a REIT or, assuming we qualify for a statutory relief provision under the Code, be required to pay a penalty tax.

Complying with REIT requirements may limit our ability to hedge effectively and may cause us to incur tax liabilities.

The REIT provisions of the Code may limit our ability to hedge our assets and operations. Under these provisions, any income that we generate from transactions intended to hedge interest rate risk will be excluded from gross income for purposes of the REIT 75% and 95% gross income tests if (i) the instrument (a) hedges interest rate risk on liabilities used to carry or acquire real estate assets or (b) hedges an instrument described in clause (a) for a period following the extinguishment of the liability or the disposition of the asset that was previously hedged by the hedged instrument, and (ii) the relevant instrument is properly identified under applicable Treasury regulations. Income from hedging transactions that do not meet these requirements will generally constitute non-qualifying income for purposes of both the REIT 75% and 95% gross income tests. As a result of these rules, we may have to limit our use of hedging techniques that might otherwise be advantageous or implement those hedges through a TRS. This could increase the cost of our hedging activities because our TRS would be subject to tax on gains or expose us to greater risks associated with changes in interest rates than we would otherwise want to bear. In addition, losses in our TRS will generally not provide any tax benefit, except for being carried back or forward against past or future taxable income in the TRS.

Legislative or regulatory tax changes related to REITs could materially and adversely affect our business.

The U.S. federal income tax laws and regulations governing REITs and their stockholders, as well as the administrative interpretations of those laws and regulations, are constantly under review and may be changed at any time, possibly with retroactive effect. No assurance can be given as to whether, when, or in what form, the U.S. federal income tax laws applicable to us and our stockholders may be enacted. Changes to the U.S. federal income tax laws and interpretations of U.S. federal tax laws could adversely affect an investment in our common stock.

Risks Related to Our Common Stock

The future sales of shares of our common stock may depress the price of our common stock and dilute stockholders’ beneficial ownership.

We cannot predict whether future issuances of shares of our common stock or the availability of shares of our common stock for resale in the open market will decrease the market price of our common stock. Any sales of a substantial number of shares of our common stock in the public market or the perception that such sales might occur, may cause the market price of our common stock to decline. In addition, future issuances of our common stock may be dilutive to existing stockholders.

In the future, we may increase our capital resources by making offerings of debt or preferred equity securities, including trust preferred securities, senior or subordinated notes and preferred stock. Upon liquidation, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings will receive distributions of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing stockholders or reduce the market price of our common stock, or both. Holders of our common stock are not entitled to preemptive rights or other protections against dilution. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future offerings reducing the market price of our common stock and diluting their stock holdings in us.

The market price and trading volume of our common stock may vary substantially.

Our common stock is listed on NASDAQ under the symbol “SELF.” The stock markets, including NASDAQ, have experienced significant price and volume fluctuations over the past several years. As a result, the market price of our common stock is likely to be similarly volatile, and investors in our common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. Accordingly, no assurance can be given as to the ability of our stockholders to sell their common stock or the price that our stockholders may obtain for their common stock.

Some of the factors that could negatively affect the market price of our common stock include:

•

our actual or projected operating results, financial condition, cash flows and liquidity or changes in business strategy or prospects;

•

actual or perceived conflicts of interest with our directors, officers and employees;

•

equity issuances by us, or share resales by our stockholders, or the perception that such issuances or resales may occur;

•

the impact of accounting principles and policies on our financial positions and results;

•

publication of research reports about us or the real estate industry;

•

changes in market valuations of similar companies;

•

adverse market reaction to any increased indebtedness we may incur in the future;

•

additions to or departures of our key personnel;

•

speculation in the press or investment community;

•

our failure to meet, or the lowering of, our earnings estimates or those of any securities analysts;

•

increases in market interest rates, which may lead investors to demand a higher distribution yield for our common stock and would result in increased interest expenses on our debt;

•

failure to maintain our REIT qualification or exclusion from registration under the 1940 Act, as amended;

•

price and volume fluctuations in the stock market generally; and

•

general market and economic conditions, including the current state of the credit and capital markets.

Market factors unrelated to our performance could also negatively impact the market price of our common stock. One of the factors that investors may consider in deciding whether to buy or sell our common stock is our distribution rate as a percentage of our stock price relative to market interest rates. If market interest rates increase, prospective investors may demand a higher distribution rate or seek alternative investments paying higher dividends or interest. As a result, interest rate fluctuations and conditions in capital markets can affect the market value of our common stock. For instance, if interest rates rise, it is likely that the market price of our common stock will decrease as market rates on interest-bearing securities increase.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

CAUTIONARY LANGUAGE

The following discussion and analysis should be read in conjunction with our selected consolidated historical financial data together with the consolidated pro forma financial data and historical financial statements and related notes thereto included elsewhere in this annual report. We make statements in this section that may be forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this annual report entitled “Statement on Forward-looking Information.”

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements contained elsewhere in this annual report, which have been prepared in accordance with generally accepted accounting principles (“GAAP”). Our notes to the consolidated financial statements contained elsewhere in this annual report describe the significant accounting policies essential to our condensed consolidated financial statements. Preparation of our financial statements requires estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions that we have used are appropriate and correct based on information available at the time they were made. These estimates, judgments and assumptions can affect our reported assets and liabilities as of the date of the financial statements, as well as the reported revenues and expenses during the period presented. If there are material differences between these estimates, judgments and assumptions and actual facts, our financial statements may be affected.

In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require our judgment in its application. There are areas in which our judgment in selecting among available alternatives would not produce a materially different result, but there are some areas in which our judgment in selecting among available alternatives would produce a materially different result. See the notes to the condensed consolidated financial statements that contain additional information regarding our accounting policies and other disclosures.

Management’s Discussion and Analysis Overview

The Company is a self-administered and self-managed REIT that owns, operates, manages, acquires, and redevelops self storage properties (“stores” or “properties”) in the United States. Our stores are designed to offer affordable, easily accessible and secure storage space for residential and commercial customers. As of December 31, 2025, the Company owned and operated, or managed, through its wholly owned subsidiaries, thirteen stores located in Connecticut, Illinois, Indiana, New York, Ohio, Pennsylvania, South Carolina, and Oklahoma. The Company was formerly registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as a non-diversified, closed end management investment company. The Securities and Exchange Commission’s (“SEC”) order approving the Company’s application to deregister from the 1940 Act was granted on January 19, 2016. On January 19, 2016, the Company changed its name to Global Self Storage, Inc. from Self Storage Group, Inc., changed its SEC registration from an investment company to an operating company reporting under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and listed its common stock on NASDAQ under the symbol “SELF”.

Our store operations generated most of our net income for all periods presented herein. Accordingly, a significant portion of management’s time is devoted to seeking to maximize cash flows from our existing stores, as well as seeking investments in additional stores. The Company expects to continue to earn a majority of its gross income from its store operations as its current store operations continue to develop and as it makes additional store acquisitions. Over time, the Company expects to divest its remaining portfolio of investment securities and use the proceeds to acquire and operate additional stores. The Company expects its income from investment securities to continue to decrease as it continues to divest its holdings of investment securities.

Financial Condition and Results of Operations

Our financing strategy is to minimize the cost of our capital in order to maximize the returns generated for our stockholders. For future acquisitions, the Company may employ various financing and capital raising alternatives including, but not limited to, debt and/or equity offerings, credit facilities, mortgage financing, and joint ventures with third parties.

On June 24, 2016, certain wholly owned subsidiaries of the Company (“Term Loan Secured Subsidiaries”) entered into a loan agreement and certain other related agreements (collectively, the “Term Loan Agreement”) between the Term Loan Secured Subsidiaries and Insurance Strategy Funding IV, LLC (the “Term Loan Lender”). Under the Term Loan Agreement, the Term Loan Secured Subsidiaries borrowed from Term Loan Lender the principal amount of $20 million pursuant to a promissory note (the “Term Loan Promissory Note”). The Term Loan Promissory Note bears interest at a rate equal to 4.192% per annum and is due to mature on July 1, 2036. Pursuant to a security agreement (the “Term Loan Security Agreement”), the obligations under the Term Loan Agreement are secured by certain real estate assets owned by the Term Loan Secured Subsidiaries. J.P. Morgan Investment Management, Inc. acted as Special Purpose Vehicle Agent of the Term Loan Lender. The Company entered into a non-recourse guaranty (the “Term Loan Guaranty” and together with the Term Loan Agreement, the Term Loan Promissory Note and the Term Loan Security Agreement, the “Term Loan Documents”) to guarantee the payment to the Term Loan Lender of certain obligations of the Term Loan Secured Subsidiaries under the Term Loan Agreement. We have used some of the proceeds from the Term Loan Agreement to acquire four self storage properties in 2016.

On December 20, 2018, certain of our wholly owned subsidiaries (“Credit Facility Secured Subsidiaries”) entered into a revolving credit loan agreement (collectively, the “Credit Facility Loan Agreement”) between the Credit Facility Secured Subsidiaries and TCF National Bank (“Credit Facility Lender”). Under the Credit Facility Loan Agreement, the Credit Facility Secured Subsidiaries may borrow from the Credit Facility Lender in the principal amount of up to $10 million pursuant to a promissory note (the “Credit Facility Promissory Note”). The Credit Facility Promissory Note bears an interest rate equal to 3.00% over the One Month U.S. Dollar London Inter-Bank Offered Rate and was due to mature on December 20, 2021. The obligations under the Credit Facility Loan Agreement are secured by certain real estate assets owned by the Credit Facility Secured Subsidiaries. We entered into a guaranty of payment on December 20, 2018 (the “Credit Facility Guaranty,” and together with the Credit Facility Loan Agreement, the Credit Facility Promissory Note and related instruments, the “Credit Facility Loan Documents”) to guarantee the payment to the Credit Facility Lender of certain obligations of the Credit Facility Secured Subsidiaries under the Credit Facility Loan Agreement. As described in more detail below, the Credit Facility Loan Agreement has been replaced in its entirety by the Amended Credit Facility Loan Agreement (as defined below) on July 6, 2021.

On December 18, 2019, we completed a rights offering whereby we sold and issued an aggregate of 1,601,291 shares of our common stock, par value $0.01 per share (“common stock”), at the subscription price of $4.18 per whole share of common stock, pursuant to the exercise of subscriptions and oversubscriptions from our stockholders. We raised aggregate gross proceeds of approximately $6.7 million in the rights offering.

On May 19, 2020, an affiliate of the Company (the “Borrower”) entered into a Paycheck Protection Program Term Note (“PPP Note”) with Customers Bank on behalf of itself, the Company, and certain other affiliates under the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The Borrower received total proceeds of $486,602 from the PPP Note. On April 5, 2022, the Borrower was granted forgiveness of the entire PPP Note and any accrued interest. Upon forgiveness, the Company received $307,210 in cash from the Borrower, which was the amount attributable to the Company under the SBA's loan determination formula, and recorded a gain for such amount in its consolidated statements of operations and comprehensive income.

On June 25, 2021, we completed an underwritten public offering whereby we sold and issued an aggregate of 1,121,496 shares of our common stock at the price of $5.35 per share. Subsequently, the over-allotment option was exercised increasing the total number of shares sold and issued to 1,289,720. We raised aggregate gross proceeds of approximately $6.9 million in the public offering after giving effect to the exercise of the over-allotment option.

On July 6, 2021, certain wholly owned subsidiaries (“Amended Credit Facility Secured Subsidiaries”) of the Company entered into a first amendment to the Credit Facility Loan Agreement (collectively, the “Amended Credit Facility Loan Agreement”) between the Amended Credit Facility Secured Subsidiaries and The Huntington National Bank, successor by merger to TCF National Bank (“Amended Credit Facility Lender”). Under the Amended Credit

Facility Loan Agreement, the Amended Credit Facility Secured Subsidiaries were able to borrow from the Amended Credit Facility Lender in the principal amount of up to $15 million, reduced to $14.75 million and $14.5 million in years 2 and 3, respectively, pursuant to a promissory note (the “Amended Credit Facility Promissory Note”). The Amended Credit Facility Promissory Note bore an interest rate equal to 3% plus the greater of the One Month U.S. Dollar London Inter-Bank Offered Rate or 0.25% and was due to mature on July 6, 2024. The publication of LIBOR ceased after June 30, 2023. The Amended Credit Facility Loan Agreement provided for a replacement index based on the Secured Overnight Financing Rate (“SOFR”). The interest rate on the Amended Credit Facility Promissory Note subsequent to June 30, 2023, was equal to 3% plus the greater of SOFR plus 0.11448% or 0.25%. The obligations under the Amended Credit Facility Loan Agreement were secured by certain real estate assets owned by the Amended Credit Facility Secured Subsidiaries. The Company entered into an amended and restated guaranty of payment on July 6, 2021 (“Amended Credit Facility Guaranty,” and together with the Amended Credit Facility Loan Agreement, the Amended Credit Facility Promissory Note and related instruments, the “Amended Credit Facility Loan Documents”) to guarantee the payment to the Amended Credit Facility Lender of certain obligations of the Amended Credit Facility Secured Subsidiaries under the Amended Credit Facility Loan Agreement. The Company and the Amended Credit Facility Secured Subsidiaries paid customary fees and expenses in connection with their entry into the Amended Credit Facility Loan Documents. As described in more detail below, the Amended Credit Facility Loan Agreement has been replaced in its entirety by the Second Amended Credit Facility Loan Agreement on July 6, 2024.

On January 14, 2022, the Company entered into an At Market Offering Sales Agreement (the “Prior Sales Agreement”) with B. Riley Securities, Inc. (the “Prior Sales Agent”) pursuant to which the Company may sell, from time to time, shares of the Company’s common stock, par value $0.01 per share, having an aggregate offering price of up to $15,000,000, through the Prior Sales Agent. During the twelve months ended December 31, 2022, under the Prior Sales Agreement, the Company sold and issued an aggregate of 373,833 shares of common stock and raised aggregate gross proceeds of approximately $2,272,628, less sales commissions of approximately $45,491 and other offering costs resulting in net proceeds of $2,008,436. Effective April 4, 2025, the Company delivered written notice to the Prior Sales Agent terminating the Prior Sales Agreement and entered into a new at market offering sales agreement with another sales agent. There were no shares of common stock sold during the three and twelve months ended December 31, 2025 under the Prior Sales Agreement.

On July 6, 2024, certain wholly owned subsidiaries (“Second Amended Credit Facility Secured Subsidiaries”) of the Company entered into a second amendment to the Credit Facility Loan Agreement (collectively, the “Second Amended Credit Facility Loan Agreement”) between the Second Amended Credit Facility Secured Subsidiaries and The Huntington National Bank, successor by merger to TCF National Bank (“Second Amended Credit Facility Lender”). Under the Second Amended Credit Facility Loan Agreement, the Second Amended Credit Facility Secured Subsidiaries may borrow from the Second Amended Credit Facility Lender in the principal amount of up to $15 million, reduced to $14.75 million and $14.5 million in years 2 and 3, respectively, pursuant to a promissory note (the “Second Amended Credit Facility Promissory Note”). The Second Amended Credit Facility Promissory Note bears an interest rate equal to 3% plus the greater of the One Month SOFR or 0.25% and is due to mature on July 6, 2027, with an option to extend the maturity to July 6, 2028. As of December 31, 2025, the effective interest rate was approximately 6.8%. An annual unused facility fee is charged based on the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during the trailing twelve month period ending each June 30. The fee will be calculated at 0.25% per annum if the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during such trailing twelve month period was greater than fifty percent, and will be calculated at 0.15% if the daily average of the unadvanced amount of the Second Amended Credit Facility Loan Agreement during such trailing twelve month period was less than or equal to fifty percent. The obligations under the Second Amended Credit Facility Loan Agreement are secured by certain real estate assets owned by the Second Amended Credit Facility Secured Subsidiaries. The Company entered into a second amended and restated guaranty of payment as of July 6, 2024 (“Second Amended Credit Facility Guaranty,” and together with the Second Amended Credit Facility Loan Agreement, the Second Amended Credit Facility Promissory Note and related instruments, the “Second Amended Credit Facility Loan Documents”) to guarantee the payment to the Second Amended Credit Facility Lender of certain obligations of the Second Amended Credit Facility Secured Subsidiaries under the Second Amended Credit Facility Loan Agreement. The Company and the Second Amended Credit Facility Secured Subsidiaries paid customary fees and expenses in connection with their entry into the Second Amended Credit Facility Loan Documents. The Company also maintains a bank account at the Second Amended Credit Facility Lender. As of December 31, 2025, we have no withdrawn proceeds under the Second Amended Credit Facility Loan Agreement. We currently intend to strategically withdraw proceeds available under the Second Amended Credit

Facility Loan Agreement to fund: (i) the acquisition of additional self storage properties, (ii) expansions at existing self storage properties in our portfolio, and/or (iii) joint ventures with third parties for the acquisition and expansion of self storage properties.

On July 8, 2024, in connection with the Second Amended Credit Facility Loan Agreement, the Company entered into a swap transaction for an interest rate derivative with Huntington (the "Cap Rate Agreement") effective July 10, 2024. The notional amount and strike is $7,500,000 and 5.25%, respectively. The cost of the initial premium was $57,000 and will be carried as an asset on the balance sheet at fair value. The Cap Rate Agreement terminates on July 6, 2027.

On April 4, 2025, the Company entered into an At Market Offering Sales Agreement (the "Sales Agreement") with A.G.P./Alliance Global Partners (the “Agent”) pursuant to which the Company may sell through the Agent, from time to time, shares of the Company’s common stock, par value $0.01 per share, having an aggregate offering price of up to $15,000,000. There were no shares of common stock sold during the three and twelve months ended December 31, 2025 under the Sales Agreement.

We continue to actively review a number of store and store portfolio acquisition opportunities and have been working to further redevelop and expand our current stores. We did not make any acquisitions in the year ended December 31, 2025. In addition, we may pursue third-party management opportunities of properties owned by certain affiliates or joint venture partners for a fee, and utilize such relationships with third-party owners as a source for future acquisitions and investment opportunities. As of December 31, 2025, we managed one third-party owned property, which was previously rebranded as “Global Self Storage,” had 137,318-leasable square feet and was comprised of 619 climate-controlled and non-climate-controlled units located in Edmond, Oklahoma.

In addition to actively reviewing a number of store and portfolio acquisition opportunities, we have been working to further redevelop and expand our current stores.

We expect we will have sufficient cash from current sources to meet our liquidity needs for the next twelve months because our capital resources currently exceed our projected expenses for the next twelve months. However, we may opt to supplement our equity capital and increase potential returns to our stockholders through the use of prudent levels of borrowings. We may use debt when the available terms and conditions are favorable to long-term investing and well-aligned with our business plan.

The Company currently has capital resources totaling approximately $24.5 million, comprised of $7.5 million of cash, cash equivalents, and restricted cash, and $2.3 million of marketable securities as of December 31, 2025, and $14.7 million available for withdrawal under the Second Amended Credit Facility Loan Agreement. Capital resources derived from retained cash flow have been and are currently expected to continue to be negligible. Retained operating cash flow represents our expected cash flow provided by operating activities, less stockholder distributions and capital expenditures to maintain stores. The Company's capital resources allow us to continue to execute our strategic business plan, which includes funding acquisitions, either directly or through joint ventures; expansion projects at our existing properties; and broadening our revenue base and pipeline of potential acquisitions through developing Global MaxManagementSM, our third-party management platform. Our board of directors regularly reviews our strategic business plan, with emphasis on capital formation, debt versus equity ratios, dividend policy, use of capital and debt, funds from operations (“FFO”) and adjusted funds from operations (“AFFO”) performance, and optimal cash levels. See the section titled "Non-GAAP Financial Measures" for the definition and use of FFO and AFFO.

We expect that the results of our operations will be affected by a number of factors. Many of the factors that will affect our operating results are beyond our control. The Company and its properties could be materially and adversely affected by the risks, or the public perception of the risks, related to, among other things, public health crises, natural disasters and geopolitical events, including the ongoing conflict between Russia, Belarus and Ukraine, the ongoing conflict between Israel and Hamas, the ongoing conflict between Iran and the United States, financial and credit market volatility and disruptions, inflationary pressures, interest rate fluctuations, supply chain issues, labor shortages and recessionary concerns.

Results of Operations for the Year Ended December 31, 2025 Compared with the Year Ended December 31, 2024

Revenues

Total revenues increased from $12,530,280 during the year ended December 31, 2024 to $12,705,245 during the year ended December 31, 2025, an increase of 1.4% or $174,965. Rental income increased from $12,024,552 during the year ended December 31, 2024 to $12,196,698 during the year ended December 31, 2025, an increase of 1.4% or $172,146‬. The increase in total revenues was due primarily to increased occupancy rates, and the results of our proprietary revenue rate management program of raising existing tenant rates.

Other store related income consists of customer insurance fees, sales of storage supplies, and other ancillary revenues. Other store related income decreased from $435,167 in the year ended December 31, 2024 to $434,804 in the year ended December 31, 2025, a decrease of 0.1% or $363.

Operating Expenses

Total expenses increased from $9,635,952 during the year ended December 31, 2024 to $9,743,894 during the year ended December 31, 2025, an increase of 1.1% or $107,942, which was primarily due to an increase in certain store operating expenses. Store operating expenses increased from $4,739,995 in the year ended December 31, 2024 to $4,864,402 in the year ended December 31, 2025, an increase of 2.6% or $124,407, which was primarily due to increased expenses in employment and utilities.

Depreciation and amortization increased from $1,634,147 in the year ended December 31, 2024 to $1,634,480 in the year ended December 31, 2025.

General and administrative expenses decreased $36,047 for the year ended December 31, 2025 as compared to the year ended December 31, 2024.

Business development, capital raising, and store acquisition expenses increased from $3,037 to $22,286 during the year ended December 31, 2025 as compared to the year ended December 31, 2024. These costs primarily consisted of consulting costs in connection with business development, capital raising, and future potential store acquisitions, and expenses related to our third party management platform marketing initiatives. The majority of these expenses are non-recurring and fluctuate based on business development activity during the time period.

Operating Income

Operating income increased from $2,894,328 during the year ended December 31, 2024 to $2,961,351 during the year ended December 31, 2025, an increase of 2.3% or $67,023, which was primarily due to increased rental income, which was partially offset by increased total expenses.

Other Income (expense)

Interest expense on debt decreased from $880,744 during the year ended December 31, 2024 to $854,052 during the year ended December 31, 2025, a decrease of 3.0% or $26,692. This decrease was attributable to lower principal balance outstanding.

Dividend and interest income was $288,573 during the year ended December 31, 2025 as compared to $276,201 during the year ended December 31, 2024. The increase was attributable to interest earned on increased cash balances.

The Company recognizes changes in the fair value of its investments in equity securities with readily determinable fair values in net income and comprehensive income and, as such, recorded an unrealized loss of $357,421 for the year ended December 31, 2025 compared to an unrealized loss of $166,042 during the year ended December 31, 2024.

Net Income

For the year ended December 31, 2025, net income was $2,038,451 or $0.18 per fully diluted share. For the year ended December 31, 2024, net income was $2,123,743 or $0.19 per fully diluted share.

Non-GAAP Financial Measures

Funds from Operations (“FFO”) and FFO per share are non-GAAP measures defined by the National Association of Real Estate Investment Trusts (“NAREIT”) and are considered helpful measures of REIT performance by REITs and many REIT analysts. NAREIT defines FFO as a REIT’s net income, excluding gains or losses from sales of property, and adding back real estate depreciation and amortization. The Company also excludes unrealized gains on marketable equity securities and gains relating to PPP loan forgiveness. FFO and FFO per share are not a substitute for net income or earnings per share. FFO is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends because it excludes financing activities presented on our statements of cash flows. In addition, other REITs may compute these measures differently, so comparisons among REITs may not be helpful. However, the Company believes that to further understand the performance of its stores, FFO should be considered along with the net income and cash flows reported in accordance with GAAP and as presented in the Company’s financial statements.

Adjusted FFO (“AFFO”) and AFFO per share are non-GAAP measures that represent FFO and FFO per share excluding the effects of stock-based compensation, business development, capital raising, and acquisition related costs and non-recurring items, which we believe are not indicative of the Company’s operating results. AFFO and AFFO per share are not a substitute for net income or earnings per share. AFFO is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends because it excludes financing activities presented on our statements of cash flows. We present AFFO because we believe it is a helpful measure in understanding our results of operations insofar as we believe that the items noted above that are included in FFO, but excluded from AFFO, are not indicative of our ongoing operating results. We also believe that the analyst community considers our AFFO (or similar measures using different terminology) when evaluating us. Because other REITs or real estate companies may not compute AFFO in the same manner as we do, and may use different terminology, our computation of AFFO may not be comparable to AFFO reported by other REITs or real estate companies. However, the Company believes that to further understand the performance of its stores, AFFO should be considered along with the net income and cash flows reported in accordance with GAAP and as presented in the Company’s financial statements.

We believe net operating income or “NOI” is a meaningful measure of operating performance because we utilize NOI in making decisions with respect to, among other things, capital allocations, determining current store values, evaluating store performance, and in comparing period-to-period and market-to-market store operating results. In addition, we believe the investment community utilizes NOI in determining operating performance and real estate values and does not consider depreciation expense because it is based upon historical cost. NOI is defined as net store earnings before general and administrative expenses, interest, taxes, depreciation, and amortization.

NOI is not a substitute for net income, net operating cash flow, or other related GAAP financial measures in evaluating our operating results.

Same-Store Self Storage Operations

We consider our same-store portfolio to consist of only those stores owned and operated on a stabilized basis at the beginning and at the end of the applicable periods presented. We consider a store to be stabilized once it has achieved an occupancy rate that we believe, based on our assessment of market-specific data, is representative of similar self storage assets in the applicable market for a full year measured as of the most recent January 1 and has not been significantly damaged by natural disaster or undergone significant renovation or expansion. We believe that same-store results are useful to investors in evaluating our performance because they provide information relating to changes in store-level operating performance without taking into account the effects of acquisitions, dispositions or new ground-up developments. As of December 31, 2025, we owned twelve same-store properties and zero non-same-store properties. The Company believes that by providing same-store results from a stabilized pool of stores, with accompanying operating metrics including, but not limited to, variances in occupancy, rental revenue, operating expenses, NOI, etc., stockholders and potential investors are able to evaluate operating performance without the effects of non-stabilized occupancy levels, rent levels, expense levels, acquisitions or completed developments. Same-store results should not be used as a basis for future same-store performance or for the performance of the Company’s stores as a whole.

Same-store occupancy as of the end of the three months and year ended December 31, 2025 increased by 10 basis points to 93.0% from 92.9% for the same period in 2024.

Same-store revenues decreased by 0.9% for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased by 1.4% for the twelve months ended December 31, 2025 versus the twelve months ended December 31, 2024. Same-store cost of operations increased by 4.5% for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased by 2.6% for the twelve months ended December 31, 2025 versus the twelve months ended December 31, 2024. Same-store NOI decreased by 4.1% for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased by 0.6% for the twelve months ended December 31, 2025 versus the twelve months ended December 31, 2024. The increase in same-store NOI for the twelve months ended December 31, 2025 versus the twelve months ended December 31, 2024 was due primarily to an increase in same-store revenues.

We believe that our results were driven by, among other things, our internet and digital marketing initiatives which helped maintain our overall average same-store occupancy of approximately 93% as of December 31, 2025. Also contributing to our results were our customer service efforts which we believe were essential in building local brand loyalty resulting in powerful referral and word-of-mouth market demand for our storage units and services.

These results are summarized as follows:

Analysis of Same-Store Revenue

For the three and twelve months ended December 31, 2025, revenue decreased 0.9% and increased 1.4%, respectively, as compared to the same periods in 2024. The increase in the twelve months ended December 31, 2025 was attributable to, among other things, increased occupancy rates, and the results of our proprietary revenue rate management program of raising existing tenant rates. Same store average overall square foot occupancy for all of the Company’s same-stores combined increased by 10 basis points to 93.0% in the twelve months ended December 31, 2025 from 92.9% in the twelve months ended December 31, 2024.

We believe that our focus on maintaining high occupancy helps us to maximize rental income at our properties. We seek to maintain an average square foot occupancy level at or above 90% by regularly adjusting the rental rates and promotions offered to attract new tenants as well as adjusting our online marketing efforts in seeking to generate

sufficient move-in volume to replace tenants that vacate. Demand may fluctuate due to various local and regional factors, including the overall economy. Demand is generally higher in the summer months than in the winter months and, as a result, rental rates charged to new tenants are typically higher in the summer months than in the winter months.

As of December 31, 2025, we observed no material degradation in rent collections. However, we believe that our bad debt losses could increase from historical levels due to (i) cumulative stress (such as inflation, recession fears, etc.) on our customers’ financial capacity and (ii) reduced rent recoveries from auctioned units.

We may experience a change in the move-out patterns of our long-term customers due to economic uncertainty. This could lead to lower occupancies and rent “roll down” as long-term customers are replaced with new customers at lower rates.

We currently expect rental income growth, if any, to come from a combination of the following: (i) continued existing tenant rent increases, (ii) higher rental rates charged to new tenants, (iii) lower promotional discounts, and (iv) higher occupancies. Our future rental income growth will likely also be dependent upon many factors for each market that we operate in, including, among other things, demand for self storage space, the level of competitor supply of self storage space, and the average length of stay of our tenants. Increasing existing tenant rental rates, generally on an annual basis, is a key component of our revenue growth. We typically determine the level of rental increases based upon our expectations regarding the impact of existing tenant rate increases on incremental move-outs. We currently expect existing tenant rent increases for 2026, if any, to be similar to, those for the year ended December 31, 2025.

It is difficult to predict trends in move-in, move-out, in place contractual rents, and occupancy levels. Current trends, when viewed in the short-term, are volatile and not necessarily predictive of our revenues going forward because they may be subject to many short-term factors. Such factors include, among others, initial move-in rates, seasonal factors, unit size and geographical mix of the specific tenants moving in or moving out, the length of stay of the tenants moving in or moving out, changes in our pricing strategies, and the degree and timing of rate increases previously passed to existing tenants.

Importantly, we continue to refine our proprietary revenue rate management program which includes regular internet data scraping of local competitors’ prices. We do this in seeking to maintain our competitive market price advantage for our various sized storage units at our stores. This program helps us in seeking to maximize each store’s occupancy and our self storage revenue and NOI. We believe that, through our various marketing initiatives, we can continue to attract high quality, long term tenants who we expect will be storing with us for years. As of December 31, 2025, our average tenant duration of stay was approximately 3.5 years, which was up from 3.4 years as of December 31, 2024.

Analysis of Same-Store Cost of Operations

Same-store cost of operations increased 4.5% or $53,268 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased 2.6% or $124,407 for the twelve months ended December 31, 2025 versus the twelve months ended December 31, 2024. This increase in same-store cost of operations for the twelve months ended December 31, 2025 was due primarily to increased expenses for employment and utilities.

Employment. On-site store manager, regional manager and district payroll expense increased 18.1% or $60,584 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased 4.5% or $63,363 for the twelve months ended December 31, 2025 as compared to the same period in 2024. This increase for 2025 versus 2024 was due primarily to routine employee additions and departures, and inflationary increases in compensation rates for existing employees. We currently expect inflationary increases in compensation rates for existing employees and other increases in compensation costs as we potentially add new stores as well as district, regional, and store managers.

Real Estate Property Tax. Store property tax expense increased 0.4% or $1,739 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and decreased 6.2% or $101,621 for the twelve

months ended December 31, 2025 as compared to the same period in 2024. The decrease in property tax expense during the year ended December 31, 2025 is primarily due to property tax relief obtained for our Dolton, IL property in 2024, which was partially offset by our increased property assessment valuations. See the section titled “Property Tax Expenses at Dolton, IL” for additional detail. We currently expect same-store property tax expenses to increase during 2026, primarily due to increased property assessment valuations.

Administrative. We classify administrative expenses as bank charges related to processing the stores’ cash receipts, credit card fees, repairs and maintenance, utilities, landscaping, alarm monitoring and trash removal. Administrative expenses decreased 11.4% or $28,618 in the three months ended December 31, 2025 as compared to the same period in 2024, and increased 10.5% or $93,896 in the twelve months ended December 31, 2025 as compared to the same period in 2024. We experienced an increase in administrative expenses for the year ended December 31, 2025 due primarily to increased utilities and landscaping expense. We currently expect moderate increases in other direct store costs in 2026.

Repairs and maintenance expense decreased 55.6% or $52,813 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and decreased 6.1% or $13,987 for the twelve months ended December 31, 2025 as compared to the same period in 2024. We experienced a decrease in repairs and maintenance expense for the year ended December 31, 2025 due primarily to a decreased number of one-off repairs in 2025 as compared to 2024.

Our utility expenses are currently comprised of electricity, oil, and gas costs, which vary by store and are dependent upon energy prices and usage levels. Changes in usage levels are driven primarily by weather and temperature. Also affecting our utilities expenses over time is our ongoing LED light replacement program at all of our stores, which has already resulted in lower electricity usage. Utility expense decreased 4.7% or $2,576 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased 25.7% or $65,364 for the twelve months ended December 31, 2025 as compared to the same period in 2024, primarily due to higher energy usage during the twelve months ended December 31, 2025 versus the same periods in 2024. It is difficult to estimate future utility costs because weather, temperature, and energy prices are volatile and unpredictable. However, based upon current trends and expectations regarding commercial electricity rates, we currently expect inflationary increases in rates resulting in higher net utility costs in 2026.

Landscaping expenses, which include snow removal costs, increased 99.9% or $24,077 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased 28.6% or $31,810 in the twelve months ended December 31, 2025 compared to the same period in 2024. The increase in landscaping expense in the twelve months ended December 31, 2025 versus the same period in 2024 is primarily due to higher snow removal costs. Landscaping expense levels are dependent upon many factors such as weather conditions, which can impact landscaping needs including, among other things, snow removal, inflation in material and labor costs, and random events. We currently expect inflationary increases in landscaping expense in 2026, excluding snow removal expense, which is primarily weather dependent and unpredictable.

Marketing. Marketing expense is comprised principally of internet advertising and the operating costs of our 24/7 kiosk and telephone call and reservation center. Marketing expense varies based upon demand, occupancy levels, and other factors. Internet advertising, in particular, can increase or decrease significantly in the short term in response to these factors. Marketing expense increased 13.1% or $11,272 for the three months ended December 31, 2025 versus the three months ended December 31, 2024, and increased 6.9% or $23,497 for the twelve months ended December 31, 2025 as compared to the same period in 2024. Based upon current trends in move-ins, move-outs, and occupancies, we currently expect marketing expense to increase in 2026.

General. Other direct store costs include general expenses incurred at the stores. General expenses include items such as store insurance, business license costs, and the cost of operating each store’s rental office including supplies and telephone and data communication lines. General expenses increased 3.1% or $3,360 in the three months ended December 31, 2025 as compared to the same period in 2024, and increased 6.0% or $26,498 in the twelve months ended December 31, 2025 as compared to the same period in 2024. The increase in general expense in the twelve months ended December 31, 2025 versus the same period in 2024 is primarily due to the addition of cloud-based accounting software that is expected to improve efficiency. We currently expect moderate increases in other direct store costs in 2026.

Lien Administration. Lien administration expenses increased 57.9% or $2,888 in the three months ended December 31, 2025 as compared to the same period in 2024, and increased 30.0% or $6,148 in the twelve months ended December 31, 2025 as compared to the same period in 2024.

Property Tax Expenses at Dolton, IL

Late in the third quarter of 2017, our Dolton, IL property was reassessed by the municipality and separately, our Class 8 tax incentive renewal hearing was held. As a result of those two events, our Dolton, IL property was reassessed at approximately 52% higher and the Class 8 tax incentive was not renewed. These events were applied retroactively to take effect on January 1, 2017. Property tax expenses have increased to $399,000 during 2020, $417,000 during 2021, $532,000 during 2022, and $559,000 during 2023. The Class 8 tax incentive phased out over the years 2017, 2018, 2019, 2020, and 2021. In 2024, tax relief was granted resulting in an approximate 17.9% reduction in tax liability to the real estate property taxes for our Dolton, IL property. We are continuing to appeal the property tax reassessment and our Class 8 tax incentive renewal status for further tax relief. However, there is no guarantee that either the assessment will be reduced or our Class 8 tax incentive status will be reinstated.

Analysis of Global Self Storage Store Expansions

In addition to actively reviewing a number of store and portfolio acquisition candidates, we have been working to further redevelop and expand our current stores. In 2020, we completed three expansion/conversion projects at our

properties located in Millbrook, NY, McCordsville, IN, and West Henrietta, NY. In 2021, 2023 and 2026, we completed conversion projects at our property located in Lima, OH.

In 2019, the Company broke ground on the Millbrook, NY expansion, which added approximately 11,800 leasable square feet of all-climate-controlled units. Upon completion in February 2020, the Millbrook, NY store's area occupancy dropped from approximately 88.6% to approximately 45.5%. As of June 30, 2021, the Millbrook, NY store’s total area occupancy was approximately 95.4%.

In the first quarter of 2020, the Company began reviewing plans to convert certain commercially-leased space to all-climate-controlled units at the McCordsville, IN property. In April 2020, the Company commenced such conversion, which resulted in a new total of 535 units and 76,360 leasable square feet at the McCordsville, IN property. Upon completion in June 2020, the McCordsville, IN store's total area occupancy dropped from what would have been approximately 97.4% to approximately 79.1%. As of June 30, 2021, the McCordsville, IN store’s total area occupancy was approximately 94.7%.

Our West Henrietta, NY store expansion project, completed in August 2020, added approximately 7,300 leasable square feet of drive-up storage units. Upon completion of the expansion project, West Henrietta, NY’s total area occupancy dropped from approximately 89.6% to approximately 77.9%. As of June 30, 2021, the West Henrietta, NY store’s total area occupancy was approximately 89.1%.

In 2021, the Company began reviewing plans to convert certain commercially-leased spaces to approximately 3,000 leasable square feet of all-climate-controlled units at the Lima, OH property. In July 2021, the Company completed such conversion, resulting in a new total of 756 units and 96,883 leasable square feet at the Lima, OH property. Upon completion, total area occupancy was approximately 94.8%. This conversion did not constitute a significant renovation or expansion because it only added approximately 3,000 leasable square feet of self storage to the property. As such, our Lima, OH property remained a same store property.

In 2022, the Company began reviewing plans to convert certain commercially-leased spaces to approximately 2,500 leasable square feet of all-climate-controlled units at the Lima, OH property. In January 2023, the Company completed such conversion, resulting in a new total of 767 units and 94,928 leasable square feet at the Lima, OH property. Upon completion, total area occupancy was approximately 91.1%. This conversion did not constitute a significant renovation or expansion because it only added approximately 2,500 leasable square feet of self storage to the property. As such, our Lima, OH property remained a same store property.

In 2025, the Company began reviewing plans to convert certain student housing space to approximately 2,400 leasable square feet of all-climate-controlled units at the Lima, OH property. In January 2026, the Company completed such conversion, resulting in a new total of 763 units and 94,931 leasable square feet at the Lima, OH property. Upon completion, total area occupancy was approximately 90.6%. This conversion did not constitute a significant renovation or expansion because it only added approximately 2,400 leasable square feet of self storage to the property. As such, our Lima, OH property remained a same store property.

Analysis of Realized and Unrealized Gains (Losses)

The unrealized loss on the Company’s investment in marketable equity securities was $357,421 and $166,042 for the years ended December 31, 2025 and 2024, respectively. As we continue to acquire and/or redevelop additional stores, as part of the funding for such activities, we may liquidate our investment in marketable equity securities and potentially realize gains or losses. As of December 31, 2025, our cumulative unrealized gain on marketable equity securities was $1,496,079. There were no realized gains or losses for the years ended December 31, 2025 and 2024.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures to ensure that information required to be disclosed in the reports we file pursuant to the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide a reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We have a disclosure controls and procedures committee, comprised of the Chief Executive Officer and Chief Financial Officer, which meets as necessary and is responsible for considering the materiality of information and determining our disclosure obligations on a timely basis.

The disclosure controls and procedures committee carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, audit committee, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP and includes those policies and procedures that:

•

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and board of directors; and

•

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Our management, including our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, our management

used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework).

Based on this assessment, our management believes that, as of December 31, 2025, our internal control over financial reporting was effective based on those criteria.

Changes in Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) that occurred during our fiscal fourth quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

Stockholders and the Board of Directors

Global Self Storage, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Global Self Storage, Inc. and its subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive income, stockholders’ equity and cash flows for the years then ended, and the related notes to the consolidated financial statements and schedule (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments.
