Public Storage (PSA) Risk Factors

ITEM 1A.    Risk Factors

In addition to the other information in our Annual Report on Form 10-K, you should consider the risks described below that we believe may be material to investors in evaluating the Company. This section contains forward-looking statements, and in considering these statements, you should refer to the qualifications and limitations on our forward-looking statements that are described in “Item 1. Business.”

Risks Related to Our Properties and Our Business

Natural disasters, terrorist attacks, civil unrest, or other events that could damage or otherwise disrupt our ability to operate our facilities could adversely impact our business and financial results.

Natural disasters, such as earthquakes, fires, hurricanes, drought, extreme temperatures and floods, terrorist attacks, civil unrest, and other events that damage our facilities or our tenants’ property, or that make our facilities temporarily unavailable, have in the past and may in the future adversely impact our business and financial results. Damage and business interruption losses could exceed the aggregate limits of our insurance coverage. In addition, because we self-insure a portion of our risks, losses below a certain level may not be covered by insurance. See Note 16 to our December 31, 2025 consolidated financial statements for a description of the risks of losses that are not covered by third-party insurance contracts. Our exposure to these types of events is increased by potential tenant claims associated with our tenant reinsurance business. In addition, perceptions about the risk of property loss from these events could negatively impact self-storage demand.

Operating costs, including property taxes, could increase.

We could be subject to increases in property or other taxes, repair and maintenance costs, payroll, utility costs, insurance premiums, workers compensation, and other operating expenses due to various factors such as inflation, labor shortages, commodity and energy price increases, weather, increases to minimum wage rates, supply chain disruptions, and changes to governmental safety and real estate use limitations and other governmental actions. Our property tax expense, generally depends upon the assessed value of our real estate facilities as determined by assessors and government agencies and, accordingly, could be subject to substantial increases if such agencies change their valuation approaches or opinions or if new laws are enacted, especially if new approaches are adopted or laws are enacted that result in increased property tax assessments in states or geographies where we have a high concentration of facilities. See also “We have exposure to increased property tax in California” below.

The acquisition of existing properties or self-storage operating companies is subject to risks that may adversely affect our growth and financial results.

We have acquired self-storage facilities and self-storage operating companies in the past, and we expect to continue to do so in the future. We face significant competition for suitable acquisition properties and companies from other real estate investors, including operating companies and private equity funds. As a result, we may be unable to acquire the companies or additional properties we desire or the purchase price for desirable companies or properties may be significantly increased. Failures or unexpected circumstances in integrating facilities or companies that we acquire, or circumstances we did not detect or anticipate during due diligence, such as environmental matters, needed repairs or deferred maintenance, customer collection issues, assumed liabilities, turnover of critical personnel involved in acquired operating companies, or the effects of increased property tax following reassessment of a newly-acquired property, as well as the general risks of real estate investment and mergers and acquisitions, could jeopardize realization of the anticipated earnings from an acquisition.

Our development program subjects us to risks.

There are significant risks involved in developing self-storage facilities, such as delays, cost increases, or inability to complete development projects due to changes in or failure to meet government or regulatory requirements, failure of revenue to meet our underwriting estimates, delays caused by weather issues, unforeseen site conditions, or personnel problems. Self-storage space is generally not pre-leased, and rent-up of newly developed space can be delayed or ongoing cash flow yields can be reduced due to competition, reductions in storage demand, or other factors.

8

There is significant competition among self-storage operators and from other storage alternatives.

Our self-storage facilities generate most of our revenue and earnings. Significant competition from self-storage operators, property developers, and other storage alternatives may adversely impact our ability to attract and retain customers and may negatively impact our ability to generate revenue. Competition in the local market areas in which many of our properties are located is significant and affects our occupancy levels, rental rates, and operating expenses, particularly advertising costs. There may be an increasing influx of capital from outside financing sources driving more money, development, and supply into the industry. Development of self-storage facilities may increase, which may intensify competition as newly developed facilities are opened. Development of self-storage facilities by other operators could increase, due to increases in availability of funds for investment or other reasons, and further intensify competition.

Demand for self-storage facilities may be affected by customer perceptions and factors outside of our control.

Significantly lower logistics costs could introduce new competitors, such as valet-style storage services, which may reduce the demand for traditional self-storage. Customer preferences and/or needs for self-storage could change, decline, or shift to other product types, thereby impacting our business model and ability to grow and/or generate revenues. Shifts in population and demographics could cause the geographical distribution of our portfolio to be suboptimal and affect our ability to maintain occupancy and attract new customers. Security incidents could result in the perception that our properties are not safe. If our customers do not feel our properties are safe, they may select competitors for their self-storage needs, or if there is an industry perception of inadequate security generally, customer use of self-storage could be negatively impacted.

Our newly developed and expanded facilities, and facilities that we manage for third party owners, may negatively impact the revenues of our legacy facilities.

We continue to develop new self-storage facilities and expand our existing self-storage facilities. In addition, we are seeking to increase the number of self-storage facilities that we manage for third party owners in exchange for a fee, many of which are in the process of stabilization and are near our existing stabilized self-storage facilities. In order to hasten the fill-up of these new facilities, we aggressively price such space during the fill-up period. While we believe that this aggressive pricing allows us to increase our market share relative to our competitors and increase the cash flows of these properties, such pricing and the added capacity may also negatively impact our existing stabilized self-storage facilities that are near these unstabilized facilities.

We may incur significant liabilities from environmental contamination or moisture infiltration.

Existing or future laws impose or may impose liability on us to clean up environmental contamination on or around properties that we currently or previously owned or operated, even if we were not responsible for or aware of the environmental contamination or even if such environmental contamination occurred prior to our involvement with the property. We have conducted preliminary environmental assessments on most of our properties, which have not identified any material liabilities. These assessments, commonly referred to as “Phase 1 Environmental Assessments,” include an investigation (excluding soil or groundwater sampling or analysis) and a review of publicly available information regarding the site and other nearby properties.

We are also subject to potential liability relating to moisture infiltration, which can result in mold or other damage to our or our customers’ property, as well as potential health concerns. When we receive a complaint or otherwise become aware that an air quality concern exists, we implement corrective measures and seek to work proactively with our customers to resolve issues, subject to our contractual limitations on liability for such claims.

We are not aware of any environmental contamination or moisture infiltration related liabilities at any of our properties that could be material to our overall business, financial condition, or results of operation. However, we may not have detected all material liabilities, we could acquire properties with material undetected liabilities, or new conditions could arise or develop at our properties, any of which could result in a cash settlement or adversely affect our ability to sell, lease, operate, or encumber affected facilities.

9

Elevated interest rate levels could adversely impact us and our tenants.

Interest rates remain elevated compared to recent years. As a result, if we issued new debt or preferred shares or refinanced our indebtedness, our debt service costs or preferred share dividend yields would likely be, based on current interest rates, significantly higher than current financing costs. Elevated interest rates also adversely impact the relative attractiveness of the dividend yield on our common shares. Increases in our cost of capital impact our assessment of the yields we consider appropriate to support pursuing property acquisition and development opportunities and thus can impact our external growth prospects. The degree and pace of these changes have had and may continue to have adverse macroeconomic effects that have and may continue to have adverse impacts on our tenants, including as a result of economic recession, increased unemployment, and increased financing costs. For more information on interest rate risk, see Part II, “Item 7A. Quantitative and Qualitative Disclosures About Market Risk”.

Economic conditions can adversely affect our business, financial condition, and growth.

Economic downturns or adverse economic or industry conditions, including those related to high levels of inflation, could adversely impact our financial results, growth, and access to capital. Our revenues and operating cash flow can be negatively impacted by reductions in employment and population levels, household and disposable income, and other general economic factors that lead to a reduction in demand for self-storage space in each of the markets in which we operate.

We have exposure to European operations through our ownership in Shurgard.

Shurgard, as an owner, operator, and developer of self-storage facilities, is subject to many of the same risks we are with respect to self-storage. However, through our investment in Shurgard, we are exposed to additional risks unique to the various European markets in which Shurgard operates, which may adversely impact our business and financial results, and many of which are referred to in Shurgard’s public filings. These risks include the following:

•Currency risks: Currency fluctuations can impact the fair value of our investment in Shurgard, our equity earnings, our ongoing dividends, and any other related repatriations of cash.

•Legislative, tax, and regulatory risks: Shurgard is subject to a variety of local, national, and pan-European laws and regulations related to permitting and land use, the environment, labor, and other areas, as well as income, property, sales, and value added and employment tax. These laws and regulations can be difficult to apply or interpret, can vary in each country or locality, and are subject to unexpected changes in their form and application due to regional, national, or local political uncertainty and other factors. Such changes, or Shurgard’s failure to comply with these laws, could subject it to penalties or other sanctions, adverse changes in business processes, and, potentially, adverse income tax, property tax, or other tax burdens.

•Impediments to capital repatriation could negatively impact the realization of our investment in Shurgard: Laws in Europe and the U.S. may create, impede, or increase our cost to repatriate distributions received from Shurgard or proceeds from the sale of Shurgard shares.

•Risks of collective bargaining: Collective bargaining, which is prevalent in certain areas in Europe, could negatively impact Shurgard’s labor costs or operations. Many of Shurgard’s employees participate in various national unions.

•Potential operating and individual country risks: Economic slowdowns or extraordinary political or social change in the countries in which it operates have posed, and could continue to pose, challenges or result in future reductions of Shurgard’s operating cash flows.

•Liquidity of our ownership stake: We have no plans to liquidate our interest in Shurgard. However, while Shurgard is a publicly held entity, if we chose to, our ability to liquidate our shares in Shurgard in an efficient manner could be limited by the level of Shurgard’s public “float” relative to any ownership stake we sought to sell. Our existing relationship with our legacy joint venture partner may place further contractual limitations on our ability to sell all of the shares we own if we desired to do so.

10

•Impediments of Shurgard’s public ownership structure: Shurgard’s strategic decisions, involving activities such as borrowing money, capital contributions, raising capital from third parties, and selling or acquiring significant assets, are determined by its board of directors. As a result, Shurgard may be precluded from taking advantage of opportunities that we would find attractive but that we may not be able to pursue separately, or it could take actions that we do not agree with.

Public health and other crises have adversely impacted, and may in the future adversely impact, our business.

Our business is subject to risks from public health and other crises like the COVID-19 pandemic, including, among others:

•risk of illness or death of our employees or tenants;

•negative impacts on economic conditions in our markets, which may reduce the demand for self-storage;

•risk that there could be an out-migration of population from major markets where we operate;

•government restrictions that (i) limit or prevent use of our facilities, (ii) limit our ability to increase rent or otherwise limit the rent we can charge, (iii) limit our ability to collect rent or evict delinquent tenants, or (iv) limit our ability to complete development and redevelopment projects;

•risk that we could experience a change in the move-out patterns of our long-term tenants due to economic uncertainty and increases in unemployment, which could lead to lower occupancies and rent “roll down” as long-term tenants are replaced with new tenants at lower rates; and

•risk of negative impacts on the cost and availability of debt and equity capital, which could have a material impact upon our capital and growth plans.

Local, state, and federal governments have and may in the future adopt regulations that could adversely impact our

operations.

Local, state, and federal governments have and may in the future adopt regulations that could adversely impact our operations, including in response to natural disasters and public health crises. For example, in response to wildfires in 2018, 2019, and early 2025 and floods in 2023, the State of California and some localities in California adopted temporary regulations that imposed certain limits on the rents we could charge at certain of our facilities and the extent to which we could increase rents to existing tenants. Similarly, in response to the COVID-19 pandemic, certain localities adopted restrictions on the use of certain of our facilities, limited our ability to increase rents, limited our ability to collect rent or evict delinquent tenants, and limited our ability to complete development and redevelopment projects. California and other jurisdictions have also adopted regulations restricting our operations relating to pricing methodologies, restrictions on fees, procedures for selling stored property of delinquent tenants, marketing restrictions related to price changes and promotional rates, zoning restrictions and other matters. Similar restrictions could be imposed in the future, including in response to significant events and these restrictions could adversely impact our operations.

Our marketing and pricing strategies may fail to be effective or may be constrained by factors outside of our control.

Marketing initiatives, including our increasing dependence on Google to source customers, may fail to be effective and could negatively impact financial performance. More than half of our new storage customers in 2025 were sourced directly or indirectly through “unpaid” search and “paid” search campaigns on Google. We believe that the vast majority of customers searching for self-storage use Google at some stage in their shopping experience. Google is providing tools to allow smaller and less sophisticated operators to bid for search terms, increasing competition for self-storage search terms. The predominance of Google in the shopping experience, as well as Google’s enabling of additional competitors to bid for placements in self-storage search terms, may reduce the number of new customers that we can procure, and/or increase our costs to obtain new customers.

In addition, the inability to utilize our pricing methodology due to regulatory or market constraints could also significantly impact our financial results.

11

We are exposed to 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.

We are subject to the risk of legal claims and proceedings (including class actions) and regulatory enforcement actions across many jurisdictions in the ordinary course of our business and otherwise, and we could incur significant liabilities and substantial legal fees from these actions. Resolution of these claims and actions may divert time and attention of our management and could involve payment of damages or expenses by us, all of which may be significant, and could damage our reputation and our brand. In addition, any such resolution could involve our agreement to terms that restrict the operation of our business. The results of legal proceedings cannot be predicted with certainty. We cannot guarantee that losses incurred in connection with any current or future legal or regulatory proceedings or actions will not exceed any provisions we may have set aside in respect of such proceedings or actions or any available insurance coverage. Any such legal claims, proceedings, and regulatory enforcement actions could negatively impact our operating results, cash flow available for distribution or reinvestment, and/or the price of our common shares.

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. For example, we have begun to

utilize artificial intelligence technologies in various aspects of our business, which are susceptible to errors and other

malfunctions which could lead to operational challenges and reputational risks.

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. In addition, the use of emerging technologies, including artificial intelligence, entails risks including risks relating to the possibility of intellectual property infringement or misappropriation; data privacy; quality control related to artificial intelligence outputs; new or enhanced governmental or regulatory scrutiny, requirements, litigation, or other liability; ethical concerns; negative consumer perceptions as to automation and artificial intelligence; or other complications or liabilities that could adversely affect our business, reputation, results of operations, or financial results. Although we have adopted policies with respect to these risks, including related to the development, deployment and monitoring of artificial intelligence tools, we cannot be certain that such policies will be effective.

The failure or disruption of our computer and communications systems, on which we are heavily dependent, could significantly harm our business.

We are heavily dependent upon automated information technology and Internet commerce, with more than half of our new customers coming from the telephone or over the Internet. We centrally manage significant components of our operations with our computer systems, including our financial information, and we also rely extensively on third-party vendors to retain data, process transactions, and provide other systems services. These systems are subject to damage or interruption from power outages, system, network, internet and telecommunications failures, hackers, including through a ransomware attack, computer worms, viruses, and other destructive or disruptive cybersecurity incidents, and catastrophic events. Such incidents could also result in significant costs to repair or replace such networks or information systems, as well as actual monetary losses in case of a cybersecurity incident that resulted in fraudulent payments or other cash transactions. Our operations could be severely impacted by a natural disaster, terrorist attack, attack by hackers, acts of vandalism, data theft, misplaced or lost data, programming or human error, or other circumstance that results in a significant outage of our systems or those of our third party providers, despite our use of back up and redundancy measures. While we may be entitled to damages if our third-party providers fail to satisfy their security-related obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award.

12

If our confidential information is compromised or corrupted, including as a result of a cybersecurity incident, our reputation and business relationships could be damaged and our financial condition and operating results could be adversely affected.

In the ordinary course of our business we acquire and store sensitive data, including personally identifiable information of our prospective and current customers and our employees. The secure processing and maintenance of this information is critical to our operations and business strategy. Although we believe we and our third-party service providers have taken commercially reasonable steps to protect the security of our confidential information, information security risks have generally increased in recent years due to the rise in new technologies and the increased sophistication and activities of perpetrators of cyberattacks. Further, new technologies such as artificial intelligence may be more capable at evading these safeguard measures. Despite our security measures, we face cybersecurity threats, including system, network, or Internet failures; cyberattacks, ransomware, and other malware; social engineering; and phishing schemes. In these cases, our information technology and infrastructure could be vulnerable and our or our customers’ or employees’ confidential information could be compromised or misappropriated. Any such cybersecurity incident, including those impacting personal information, could result in serious and harmful consequences for us or our customers. A cybersecurity incident could also interfere with our ability to comply with financial reporting requirements. Additionally, future or past business transactions (such as acquisitions or integrations) could expose us to additional cybersecurity risks and threats, as our systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies. Furthermore, we may discover security issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into our information technology environment and security program.

Our confidential information may also be compromised due to programming or human error, negligence, or fraud. Although we and our third-party service providers make efforts to maintain the security and integrity of our information, including the implementation of security measures, required employee awareness training, and the existence of a disaster recovery plan, there is no guarantee that they will be adequate to safeguard against all cybersecurity incidents or misuses of data. In addition, as the regulatory environment related to information security, data collection and use, and privacy becomes increasingly rigorous, with new and changing requirements applicable to our business from multiple regulatory agencies at the local, state, federal, or international level, compliance with those requirements could also result in additional costs, or we could fail to comply with those requirements due to various reasons.

Any such access, disclosure, or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties, disruption to our operations and the services we provide to customers, or damage to our reputation, any of which could adversely affect our results of operations, reputation, and competitive position. In addition, our customers could lose confidence in our ability to protect their personal information, which could cause them to discontinue leasing our self-storage facilities. Such events could lead to lost future revenues and adversely affect our results of operations, or result in remedial and other costs, fines, or lawsuits, which could exceed any available insurance that we have procured.

We have identified and expect to continue to identify cyberattacks and cybersecurity incidents on our systems and those of third parties we rely upon, but none of the cyberattacks and incidents we have identified to date has had a material impact on our business or operations. While we have purchased cybersecurity insurance, there are no assurances that the coverage would be adequate in relation to any incurred losses. Moreover, as cyberattacks increase in frequency and magnitude, we may be unable to obtain cybersecurity insurance in amounts and on terms we view as adequate for our operations.

Further information relating to cybersecurity risk management is discussed in Item 1C. “Cybersecurity” in this report.

If we fail to successfully execute our recent leadership succession, we may struggle to effectively execute our strategic plan.

We recently announced leadership changes, including a change in our Chairman of the Board, our President and Chief Executive Officer and our Chief Financial Officer. Although these changes were made pursuant to the Board’s succession planning efforts, there is no guarantee that the transition to new leadership will be executed successfully. Failure to successfully implement these successions may result in disruptions in the execution of our strategic plan. Failure to successfully implement future succession plans for other key employees may leave us vulnerable to retirements and turnover.

13

We may be harmed if we fail to protect our intellectual property adequately.

We maintain a portfolio of trademarks and trade dress that we believe are fundamental to the success of the Public Storage® brand. While we actively seek to enforce and protect our rights, failure to adequately protect our rights could lead to loss of such trademark and trade dress protection. We also own and may seek to protect other intellectual property, such as propriety systems, processes, data, and other trade secrets that we have collected and developed in the course of operating our business and that we believe provides us with various competitive advantages. Our protections could be inadequate or we could lose rights to our other intellectual property and trade secrets. Competitor use of our trademarks and trade names could lead to likelihood of confusion, tarnishment of our brand, and loss of legal protection for our marks.

We may be subject to labor disruptions related to unionization efforts.

Our employees have been and may in the future be subject to unionization efforts. These activities could lead to labor disruptions which could adversely impact our ability to operate our business and could negatively impact our reputation. In addition, these activities could result in collective bargaining agreements, which could result in increased operating and legal costs.

We may record losses as a result of the bankruptcy, insolvency, or other credit failure of the borrowers under our

bridge lending financing program. In that case, our revenues and results of operations may be materially and

adversely impacted.

Although we conduct due diligence and aim to carefully evaluate the risks associated with this debt and other investments, we could incur losses from our lending decisions, which includes subjective and complex judgments and forecasts of economic conditions and how these economic predictions might impair the ability of our borrowers to operate their business and/or make all required payments. For example, volatility of the capital and credit markets, increased interest rates, lower demand for self-storage and general economic conditions may adversely affect the solvency, creditworthiness or operations of our borrowers. If our forecasts prove incorrect, or if any of our borrowers fail to perform as expected, we may incur losses from these bridge loans which could have a material adverse effect on our operating revenue and results of operations.

Risks Related to Our Ownership, Organization and Structure

Takeover attempts or changes in control could be thwarted, even if beneficial to shareholders.

In certain circumstances, shareholders might desire a change in control or acquisition of us in order to realize a premium over the then-prevailing market price of our shares or for other reasons. However, the following could prevent, deter, or delay such a transaction:

•Provisions of Maryland law may impose limitations that may make it more difficult for a third party to negotiate or effect a business combination transaction or control share acquisition with Public Storage. Currently, our Board has opted not to subject the Company to these provisions of Maryland law, but it could choose to do so in the future without shareholder approval.

•To protect against the loss of our REIT status due to concentration of ownership levels, our declaration of trust generally limits the ability of a person, other than the Hughes family or “designated investment entities” (each as defined in our declaration of trust), to own, actually or constructively, more than 3% of our outstanding common shares or 9.9% of the outstanding shares of any class or series of preferred or equity shares. Our Board may grant, and has previously granted, a specific exemption. These limits could discourage, delay, or prevent a transaction involving a change in control of the Company not approved by our Board.

•Similarly, current provisions of our declaration of trust and powers of our Board could have the same effect, including (1) limitations on removal of trustees, (2) restrictions on the acquisition of our shares of beneficial interest, (3) the power to issue additional common shares, preferred shares, or equity shares on terms approved by our Board without obtaining shareholder approval, (4) the advance notice provisions of our bylaws, and (5) our Board’s ability under Maryland law, without obtaining shareholder approval, to implement takeover defenses that we may not yet have and to take, or refrain from taking, other actions that could have the effect of delaying, deterring, or preventing a transaction or a change in control.

14

Holders of our preferred shares have dividend, liquidation, and other rights that are senior to the rights of the holders of our common shares.

Holders of our preferred shares are entitled to cumulative dividends before any dividends may be declared or set aside on our common shares. Upon liquidation, holders of our preferred shares will receive a liquidation preference of $25,000 per share (or $25.00 per depositary share) plus any accrued and unpaid distributions before any payment is made to the common shareholders. These preferences may limit the amount received by our common shareholders either from ongoing distributions or upon liquidation. In addition, our preferred shareholders have the right to elect two additional directors to our Board whenever dividends are in arrears in an aggregate amount equivalent to six or more quarterly dividends, whether or not consecutive.

Public Storage is a holding company with no direct operations, and it relies on funds received from PSA OP and PSOC to pay its obligations and make distributions to shareholders

Public Storage is a holding company with no direct operations. All of Public Storage’s property ownership, development, and related business operations are conducted through PSOC (which is wholly-owned by PSA OP) and Public Storage has no material assets or liabilities other than its investment in PSA OP. As a result, Public Storage relies on distributions from PSA OP, which in turn relies on distributions from PSOC, to make common and preferred share dividend payments. Although Public Storage exercises control over PSA OP and PSOC, including the authority to cause PSA OP and PSOC to make distributions, in connection with our future acquisition activities or otherwise, PSA OP may issue additional units of limited partnership to third parties, and these limited partners may negotiate for certain rights. In addition, because Public Storage is a holding company, shareholder claims are structurally subordinated to all existing and future liabilities of PSA OP and PSOC and their subsidiaries. Therefore, in the event of a bankruptcy, insolvency, liquidation or reorganization of PSA OP or PSOC, or their subsidiaries, assets of PSA OP or PSOC or the applicable subsidiary will be available to satisfy any claims of our shareholders only after such liabilities and obligations have been satisfied in full.

Holders of our preferred shares are subject to certain risks.

Holders of our preferred shares have preference rights over our common shareholders with respect to liquidation and distributions, which give them some assurance of continued payment of their stated dividend rate, and receipt of their principal upon liquidation of the Company or redemption of their securities. However, holders of our preferred shares should consider the following risks:

•The Company has in the past, and could in the future, issue or assume additional debt. Preferred shareholders would be subordinated to the interest and principal payments of such debt, which would increase the risk that there would not be sufficient funds to pay distributions or liquidation amounts to the preferred shareholders.

•The Company has in the past, and could in the future, issue additional preferred shares that, while pari passu to the existing preferred shares, increases the risk that there would not be sufficient funds to pay distributions to the preferred shareholders.

•While the Company has no plans to do so, if the Company were to lose its REIT status or no longer elect REIT status, it would no longer be required to distribute its taxable income to maintain REIT status. If, in such a circumstance, the Company ceased paying dividends, unpaid distributions to the preferred shareholders would continue to accumulate. The preferred shareholders would have the ability to elect two additional members to serve on our Board until the arrearage was cured. The preferred shareholders would not receive any compensation (such as interest) for the delay in the receipt of distributions, and it is possible that the arrearage could accumulate indefinitely.

•Holders of our Preferred Shares have limited rights in the event the Company ceases to pay dividends to shareholders and have no rights with respect to a Company decision to discontinue listing the Preferred Shares on a national securities exchange or file reports with the SEC, including following a change of control transaction.

15

Risks Related to Government Regulations and Taxation

We would incur adverse tax consequences if we failed to qualify as a REIT, and we would have to pay substantial U.S. federal corporate income taxes.

REITs are subject to a range of complex organizational and operational requirements. A qualifying REIT does not generally incur U.S. federal corporate income tax on its “REIT taxable income” (generally, taxable income subject to specified adjustments, including a deduction for dividends paid and excluding net capital gain) that it distributes to its shareholders. Our REIT status is also dependent upon the REIT qualification of PS Business Parks, Inc. (“PSB”) through

the end of its taxable year ended December 31, 2022, as a result of our substantial ownership interest in it prior to the

closing of the PSB merger with an unaffiliated third party. We believe we have qualified as a REIT and we intend to continue to maintain our REIT status.

However, there can be no assurance that we qualify or will continue to qualify as a REIT, because of the highly technical nature of the REIT rules, the ongoing importance of factual determinations, the possibility of unidentified issues in prior periods, or changes in our circumstances, as well as share ownership limits in our declaration of trust that may fail to ensure that our shareholder base is sufficiently diverse for us to qualify as a REIT. For any year we fail to qualify as a REIT, unless certain relief provisions apply (the granting of such relief could nonetheless result in significant excise or penalty taxes), we would not be allowed a deduction for dividends paid, we would be subject to U.S. federal corporate income tax on our taxable income, and generally we would not be allowed to elect REIT status until the fifth year after such a disqualification. In addition, for tax years beginning after December 31, 2022, we could also be subject to certain taxes enacted by the Inflation Reduction Act of 2022 that are applicable to non-REIT corporations, including the corporate alternative minimum tax and nondeductible one percent excise tax on certain stock repurchases. Any taxes, interest, and penalties incurred would reduce our cash available for distributions to shareholders and could negatively affect our stock price. However, for years in which we failed to qualify as a REIT, we would not be subject to REIT rules that require us to distribute substantially all of our taxable income to our shareholders.

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

Dividends payable by REITs may be taxed at higher rates than dividends of non-REIT corporations. The maximum U.S. federal income tax rate for qualified dividends paid by domestic non-REIT corporations to U.S. stockholders that are individuals, trusts, or estates is generally 20%. Dividends paid by REITs to such stockholders are generally not eligible for that rate but, such stockholders may deduct up to 20% of ordinary dividends (i.e., dividends not designated as capital gain dividends or qualified dividend income) received from a REIT for taxable years beginning before January 1, 2026. Although this deduction reduces the effective tax rate applicable to certain dividends paid by REITs, such tax rate may still be higher than the tax rate applicable to regular corporate qualified dividends. This may cause investors to view REIT investments as less attractive than investments in non-REIT corporations, which in turn may adversely affect the value of the stock of REITs, including our stock.

We may pay some taxes, reducing cash available for shareholders.

Even if we qualify as a REIT for U.S. federal corporate income tax purposes, we may be subject to some federal, foreign, state, and local taxes on our income and property. Certain consolidated corporate subsidiaries of the Company have elected to be treated as taxable REIT subsidiaries (“TRSs”) for U.S. federal corporate income tax purposes and are taxable as regular corporations and subject to certain limitations on intercompany transactions. If tax authorities determine that amounts paid by our TRSs to us are not reasonable compared to similar arrangements among unrelated parties, we could be subject to a 100% penalty tax on the excess payments, and ongoing intercompany arrangements could have to change, resulting in higher ongoing tax payments. To the extent the Company is required to pay federal, foreign, state, or local taxes, or federal penalty taxes due to existing laws or changes thereto, we will have less cash available for distribution to shareholders.

In addition, certain local and state governments have imposed taxes on self-storage rent. While in most cases those taxes are paid by our customers, they increase the cost of self-storage rental to our customers and can negatively impact our revenues. Other local and state governments may impose self-storage rent taxes in the future.

If PSA OP were to fail to maintain its status as a partnership for U.S. federal income tax purposes, our financial results would be adversely impacted.

We believe PSA OP qualifies as a partnership for U.S. federal income tax purposes. As a partnership, PSA OP is generally not subject to U.S. federal income tax on its income. Instead, each of the partners is allocated its share of PSA OP’s income. There is no assurance, however, that the IRS will not challenge the status of PSA OP as a partnership for U.S. federal income tax purposes. If the IRS were to successfully challenge the status of PSA OP as a partnership, it would be taxable as a corporation. In such event, this would reduce the amount of distributions that PSA OP could make. The treatment of PSA OP as a corporation would also cause us to fail to qualify as a REIT. This would substantially reduce our cash available to pay distributions and the return on a shareholder's investment.

Changes in tax laws could negatively impact us.

The United States Treasury Department and Congress frequently review federal income tax legislation, regulations and other guidance. We cannot predict whether, when, or to what extent new federal tax laws, regulations, interpretations or rulings will be adopted, but these changes might include, in particular, increases in the U.S. federal income tax rates that apply to us or our shareholders in certain circumstances, possibly with retroactive effect.

We have exposure to increased property tax in California.

Due to the impact of Proposition 13, which generally limits increases in assessed values to 2% per year, the assessed value and resulting property tax we pay is less than it would be if the properties were assessed at current estimated market values. From time to time, proposals have been made to reduce the beneficial impact of Proposition 13, most recently in the November 2020 ballot. While this ballot initiative failed, there can be no assurance that future initiatives or other legislative actions will not eliminate or reduce the benefit of Proposition 13 with respect to our properties. If the beneficial effect of Proposition 13 were ended for our properties, our property tax expense could increase substantially, adversely affecting our cash flow from operations and net income.

We are subject to extensive laws and regulations and to frequent changes in such laws and regulations.

We are subject to extensive laws and regulations, and to frequent changes in such laws and regulations, at the city, county, state, and federal level. These laws and regulations include (i) laws and regulations related to access to our self-storage facilities, including the Americans with Disabilities Act of 1990, (ii) laws and regulations related to taxes, including property taxes, income taxes, and REIT status compliance, (iii) labor and employment laws and regulations, (iv) consumer protection laws and regulations, including those related to lien sales, (v) state and local business licensing laws and regulations, (vi) zoning laws and regulations, (vii) privacy laws and regulations, including the California Privacy Rights Act and the California Consumer Privacy Act, and (viii) securities laws. Compliance with these laws and regulations, including changes thereto, have imposed significant costs and could in the future impose greater costs or require adverse changes to our business and operations. Failure to comply with applicable laws and regulations may subject us to increased litigation and regulatory actions and negatively affect our business and operations or reputation.

Our tenant reinsurance business is subject to governmental regulation, which could reduce our profitability or limit our growth.

We hold limited lines self-service storage insurance agent licenses from a number of individual state departments of insurance and are subject to state governmental regulation and supervision. Our continued ability to maintain these limited lines self-service storage insurance agent licenses in the jurisdictions in which we are licensed depends on our compliance with related rules and regulations. The regulatory authorities in each jurisdiction generally have broad discretion to grant, renew, and revoke licenses and approvals, to promulgate, interpret, and implement regulations, and to evaluate compliance with regulations through periodic examinations, audits, and investigations of the affairs of insurance agents. As a result of regulatory or private action in any jurisdiction, we may be temporarily or permanently suspended from continuing some or all of our reinsurance activities, or otherwise fined, penalized, or subject to an adverse judgment, which could reduce our net income.

In the event that we recognize a significant gain from cash settlement of a forward sale agreement, the U.S. federal income tax treatment of the cash that we receive in such instance is unclear and could impact our ability to meet the REIT qualification requirements.

We maintain an “at the market” offering program under which we may enter into forward sale agreements from time to time to sell common shares and, subject to certain conditions, we have the right to elect physical, cash or net share settlement under these agreements at any time and from time to time, in part or in full. In the event that we elect to settle a forward sale agreement for cash and the settlement price is below the forward sale price, we would be entitled to receive a cash payment from the applicable forward purchaser(s). Under Section 1032 of the Code, generally, no gains and losses are recognized by a corporation in dealing in its own shares, including pursuant to a “securities futures contract,” as defined in the Code by reference to the Securities Exchange Act of 1934, as amended. Although we believe that any amount received by us in exchange for our common shares would qualify for the exemption under Section 1032 of the Code, because it is not entirely clear whether a forward sale agreement qualifies as a “securities futures contract,” the U.S. federal income tax treatment of any cash settlement payment we receive is uncertain. In the event that we recognize a significant gain from the cash settlement of a forward sale agreement, we might not be able to satisfy the gross income requirements applicable to REITs under the Code. If we were to fail to satisfy one or both of the gross income tests for any taxable year, we may nevertheless qualify as a REIT for such year if we were entitled to relief under certain provisions of the Code. If these relief provisions were inapplicable, we would not qualify to be taxed as a REIT.

International trade disputes, including U.S. trade tariffs and retaliatory tariffs, could adversely impact our business.

International trade disputes, including threatened or implemented tariffs imposed by the U.S. and threatened or implemented tariffs imposed by foreign countries in retaliation, could result in inflationary pressures that directly impact our costs, such as costs for steel, lumber and other materials applicable to our development and redevelopment projects. Trade disputes could also adversely impact global supply chains which could further increase costs for us or delay delivery of key inventories and supplies. Tariffs and trade restrictions can be announced with little or no advance notice, and we may not be able to effectively mitigate all adverse impacts from such measures. If we are not able to navigate these changes, it could have a material adverse effect on our business.
