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

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) should be read in conjunction with our consolidated financial statements and notes thereto.

Critical Accounting Estimates

The preparation of consolidated financial statements and related disclosures in conformity with U.S. generally accepted accounting principles (“GAAP”) requires us to make judgments, assumptions, and estimates that affect the amounts reported. On an ongoing basis, we evaluate our estimates and assumptions. These estimates and assumptions are based on current facts, historical experience, and various other factors that we believe are reasonable under the circumstances to determine reported amounts of assets, liabilities, revenues, and expenses that are not readily apparent from other sources.

We believe the following are our critical accounting estimates, because they are reasonably likely to have a material impact on the portrayal of our financial condition and results, and they require us to make judgments and estimates about matters that involve a significant level of uncertainty.

Impairment of Long-Lived Assets: The analysis of impairment of our long-lived assets, including our real estate facilities, involves identification of indicators of impairment, including unfavorable operational results and significant cost overruns on construction, projections of future operating cash flows, and estimates of fair values, all of which require significant judgment and subjectivity. In particular, these estimates are sensitive to significant assumptions, such as the projections of future rental rates, stabilized occupancy level, future profit margin, discount rates, and capitalization rates, all of which could be affected by our expectations about future market or economic conditions. Others could come to materially different conclusions.

Allocating Purchase Price for Acquired Real Estate Facilities: We estimate the fair values of the assets and liabilities of acquired real estate facilities, which consist principally of land, buildings and acquired customers in place, for purposes of allocating the aggregate purchase price of acquired real estate facilities. We estimate the fair value of land based upon price per square foot derived from observable transactions involving comparable land in similar locations as adjusted for location quality, parcel size, and date of sale associated with the acquired facilities. The fair value estimate of land is sensitive to the adjustments made to the land market transactions used in the estimate, particularly when there is a lack of recent comparable land market data. We estimate the fair value of buildings primarily using the income approach by estimating the fair value of hypothetical vacant acquired facilities and adjusting for the estimated fair value of land. The fair value estimate of buildings is sensitive to assumptions, such as lease-up period, future stabilized operating cash flows,

capitalization rate and discount rate. We estimate the fair value of acquired customers in place using the income approach by estimating the foregone rent over the presumed period of time to absorb the occupied spaces as if they were vacant at the time of acquisition. The fair value estimate of the acquired customers in place is sensitive to the assumptions used in the income approach, such as market rent, lease-up period and discount rate. Others could come to materially different conclusions as to the estimated fair values of land, buildings and acquired customers in place, which would result in different depreciation and amortization expense, gains and losses on sale of real estate assets, as well as the level of land and buildings on our consolidated balance sheet.

Overview

Our self-storage operations generate most of our net income, and our earnings growth is impacted by the levels of organic growth within our Same Store Facilities (as defined below) as well as within our Acquired Facilities and Newly Developed and Expanded Facilities (both as defined below).

During 2025, revenues generated by our Same Store Facilities remained relatively unchanged, as compared to 2024, while Same Store cost of operations increased by 1.8% ($16.6 million). Softness in demand for our storage space has led to lower move-in rental rates for new tenants and lower average occupancy in 2025 as compared to 2024. Existing customers behavior was strong in 2025 with fewer move-outs and lower delinquencies allowing for rental rate increases to tenants over their tenancy.

We have grown and plan to continue to grow through the acquisition and development of new facilities and expansion of our existing self-storage facilities. Since the beginning of 2023, we acquired a total of 273 facilities with 19.9 million net rentable square feet for $3.9 billion. Within our Non-Same Store portfolio (as defined below) as of December 31, 2025, our Newly Developed and Expanded Facilities include a total of 111 self-storage facilities with 13.3 million net rentable square feet. For development and expansions completed by December 31, 2025, we incurred a total cost of $1.7 billion. During 2025, combined net operating income generated by our Acquired Facilities and Newly Developed and Expanded Facilities increased 25.6% ($59.5 million), as compared to 2024.

We have embarked on a solar program under which we plan to install solar panels on over 1,600 of our self-storage facilities. We have completed the installations on 1,191 facilities through December 31, 2025. We spent approximately $71 million on the program in 2025, and expect to spend approximately $60 million in 2026 on this effort.

During 2025, PSOC completed public offerings of $875 million aggregate principal amount of senior notes in various tranches and maturities and €425 million of senior notes due 2034. PSOC also repaid at maturity $400 million aggregate principal amount of floating rate senior notes and €242 million aggregate principal amount of senior notes. We plan to use the remaining proceeds for general corporate purposes, including to make investments in self-storage facilities.

Results of Operations

Operating Results for 2025 and 2024

In 2025, net income allocable to our common shareholders was $1.6 billion or $9.01 per diluted common share, compared to $1.9 billion or $10.64 per diluted common share in 2024, representing a decrease of $287.1 million or $1.63 per diluted common share. The decrease was due primarily to (i) a $317.8 million increase in foreign currency exchange losses, (ii) a $22.1 million increase in depreciation and amortization expense (iii) a $17.1 million increase in interest expense, partially offset by (iv) a $53.1 million increase in self-storage net operating income and (v) a $23.4 million increase in ancillary net operating income.

The $53.1 million increase in self-storage net operating income in 2025 as compared to 2024 was a result of a $68.4 million increase attributable to our Non-Same Store Facilities, partially offset by a $15.3 million decrease attributable to our Same Store Facilities. Revenues for the Same Store Facilities remained relatively unchanged in 2025 as compared to 2024, due primarily to higher realized annual rent per occupied square foot partially offset by a decline in average occupancy. Cost of operations for the Same Store Facilities increased by 1.8% or $16.6 million in 2025 as compared to 2024, due primarily to increased property tax expense and indirect cost of operation partially offset by decreased marketing expenses and on-site property manager payroll expense. The increase in net operating income of $68.4 million for the Non-Same Store Facilities was due primarily to the impact of facilities acquired in 2025 and 2024.

Operating Results for 2024 and 2023

In 2024, net income allocable to our common shareholders was $1.9 billion or $10.64 per diluted common share, compared to $1.9 billion or $11.06 per diluted common share in 2023, representing a decrease of $76.1 million or $0.42 per diluted common share. The decrease was due primarily to (i) an $159.7 million increase in depreciation and amortization expense, (ii) an $86.3 million increase in interest expense, (iii) a $26.0 million increase in general and administrative expense, (iv) an $18.4 million decrease in interest and other income, partially offset by (v) an $153.4 million increase in foreign currency exchange gains primarily associated with our Euro denominated notes payable and (vi) a $61.6 million increase in self-storage net operating income.

The $61.6 million increase in self-storage net operating income in 2024 as compared to 2023 was a result of a $103.4 million increase attributable to our Non-Same Store Facilities, partially offset by a $41.8 million decrease attributable to our Same Store Facilities. Revenues for the Same Store Facilities decreased 0.6% or $22.7 million in 2024 as compared to 2023, due primarily to a decline in occupancy. Cost of operations for the Same Store Facilities increased by 2.1% or $19.1 million in 2024 as compared to 2023, due primarily to increased property tax expense, marketing expense, and repairs and maintenance expense, partially offset by decreased indirect cost of operations, utility expenses and on-site property manager payroll expense. The increase in net operating income of $103.4 million for the Non-Same Store Facilities was due primarily to the impact of facilities acquired in 2024 and 2023.

Funds from Operations and Core Funds from Operations

Funds from Operations (“FFO”) and FFO per diluted common share (“FFO per share”) are non-GAAP measures defined by Nareit. We believe that FFO and FFO per share are useful to REIT investors and analysts in measuring our performance because Nareit’s definition of FFO excludes items included in net income that do not relate to or are not indicative of our operating and financial performance. FFO represents net income before real estate-related depreciation and amortization, which is excluded because it is based upon historical costs and assumes that building values diminish ratably over time, while we believe that real estate values fluctuate due to market conditions. FFO also excludes gains or losses on sale of real estate assets and real estate impairment charges, which are also based upon historical costs and are impacted by historical depreciation. FFO and FFO per share are not a substitute for net income or earnings per share. FFO is not a substitute for net cash flow in evaluating our liquidity or ability to pay dividends, because it excludes investing and financing activities presented on our consolidated statements of cash flows. In addition, other REITs may compute these measures differently, so comparisons among REITs may not be helpful.

For the year ended December 31, 2025, FFO was $15.81 per diluted common share as compared to $17.19 and $16.60 per diluted common share for the years ended December 31, 2024 and 2023, respectively, representing a decrease in 2025 of 8.0%, or $1.38 per diluted common share, as compared to 2024.

We also present “Core FFO” and “Core FFO per share” non-GAAP measures that represent FFO and FFO per share excluding the impact of (i) foreign currency exchange gains and losses, (ii) charges related to the redemption of preferred securities, and (iii) certain other non-cash and/or nonrecurring income or expense items primarily representing, with respect to the periods presented below, the impact of corporate transformation costs, loss contingencies, due diligence costs incurred in pursuit of strategic transactions, realized or unrealized gain or loss on private equity investments, income tax benefits from the sale of solar tax credits, a cash and stock hiring bonus for a new senior executive and amortization of acquired non real estate-related intangibles. We review Core FFO and Core FFO per share to evaluate our ongoing operating performance and we believe they are used by investors and REIT analysts in a similar manner. However, Core FFO and Core FFO per share are not substitutes for net income and net income per share. Because other REITs may not compute Core FFO or Core FFO per share in the same manner as we do, may not use the same terminology or may not present such measures, Core FFO and Core FFO per share may not be comparable among REITs.

Analysis of Net Income — Self-Storage Operations

Our self-storage operations are analyzed in four groups: (i) 2,565 facilities that we have owned and operated on a stabilized basis since January 1, 2023 (the “Same Store Facilities”), (ii) 273 facilities we acquired since January 1, 2023 (the “Acquired Facilities”), (iii) 111 facilities that have been newly developed or expanded, or that had commenced expansion by December 31, 2025 (the “Newly Developed and Expanded Facilities”), and (iv) 222 other facilities, which are otherwise not stabilized with respect to occupancies or rental rates since January 1, 2023 (the “Other Non-Same Store Facilities”). The Acquired Facilities, Newly Developed and Expanded Facilities, and Other Non-Same Store Facilities are collectively referred to as the “Non-Same Store Facilities”. See Note 15 to our December 31, 2025 consolidated financial statements “Segment Information,” for a reconciliation of the amounts in the tables below to our total net income.

(a)Net operating income or “NOI” is a non-GAAP financial measure that excludes the impact of depreciation and amortization expense, which is based upon historical real estate costs and assumes that building values diminish ratably over time, while we believe that real estate values fluctuate due to market conditions. We utilize NOI in determining current property values, evaluating property performance, and evaluating property operating trends. We believe that investors and analysts utilize NOI in a similar manner. NOI is not a substitute for net income, operating cash flow, or other related financial measures, in evaluating our operating results. See Note 15 to our December 31, 2025 consolidated financial statements for a reconciliation of NOI to our total net income for all periods presented.

(b)Revenues and cost of operations do not include tenant reinsurance and merchandise sale revenues and expenses generated at the facilities. See “Ancillary Operations” below for more information.

Same Store Facilities

The Same Store Facilities consist of facilities we have owned and operated on a stabilized level of occupancy, revenues, and cost of operations since January 1, 2023. Our Same Store Facilities increased from 2,507 facilities at December 31, 2024 to 2,565 at December 31, 2025. The composition of our Same Store Facilities allows us more effectively to evaluate the ongoing performance of our self-storage portfolio in 2023, 2024, and 2025 and exclude the impact of fill-up of unstabilized facilities, which can significantly affect operating trends. We believe investors and analysts use Same Store Facilities information in a similar manner. However, because other REITs may not compute Same Store Facilities in the same manner as we do, may not use the same terminology or may not present such a measure, Same Store Facilities may not be comparable among REITs.

The following table summarizes the historical operating results (for all periods presented) of these 2,565 facilities (175.3 million net rentable square feet) that represent approximately 76% of the aggregate net rentable square feet of our U.S. consolidated self-storage portfolio at December 31, 2025. It includes various measures and detail that we do not include in the analysis of the developed, acquired, and other Non-Same Store Facilities, due to the relative magnitude and importance of the Same Store Facilities relative to our other self-storage facilities.

(a)Revenues and cost of operations do not include tenant reinsurance and merchandise sale revenues and expenses generated at the facilities. See “Ancillary Operations” below for more information.

(b)Direct net operating income (“Direct NOI”), a subtotal within NOI, is a non-GAAP financial measure that excludes the impact of supervisory payroll, centralized management costs, and share-based compensation in addition to depreciation and amortization expense. We utilize direct net operating income in evaluating property performance and in evaluating property operating trends as compared to our competitors.

(c)Realized annual rent per occupied square foot is computed by dividing rental income, before late charges and administrative fees, by the weighted average occupied square feet for the period. Realized annual rent per available square foot (“REVPAF”) is computed by dividing rental income, before late charges and administrative fees, by the total available net rentable square feet for the period. These measures exclude late charges and administrative fees in order to provide a better measure of our ongoing level of revenue. Late charges are dependent upon the level of delinquency, and administrative fees are dependent upon the level of move-ins. In addition, the rates charged for late charges and administrative fees can vary independently from rental rates. These measures take into consideration promotional discounts, which reduce rental income.

(d)Annual contract rent represents the agreed upon monthly rate that is paid by our tenants in place at the time of measurement. Contract rates are initially set in the lease agreement upon move-in, and we adjust them from time to time with notice. Contract rent excludes other fees that are charged on a per-item basis, such as late charges and administrative fees, does not reflect the impact of promotional discounts, and does not reflect the impact of rents that are written off as uncollectible.

(e)Represents the absolute nominal change with respect to gross margin and square foot occupancy, and the percentage change with respect to all other items.

Analysis of Same Store Revenue

We believe a balanced occupancy and rate strategy maximizes our revenues over time. We regularly adjust rental rates and promotional discounts offered (generally, “$1.00 rent for the first month”), as well as our marketing efforts to maximize revenue from new tenants to replace tenants that vacate.

We typically increase rental rates to our long-term tenants (generally, those who have been with us for at least five months) every six to twelve months. As a result, the number of long-term tenants we have in our facilities is an important factor in our revenue growth. The level of rate increases to long-term tenants is based upon evaluating the additional revenue from the increase against the negative impact of incremental move-outs, by considering tenants’ in-place rent and prevailing market rents, among other factors.

Comparison of the Year Ended December 31, 2025 to the Year Ended December 31, 2024

Revenues generated by our Same Store Facilities remained relatively unchanged compared to 2024, due primarily to a 0.5% increase in realized annual rent per occupied square foot partially offset by a 0.4% decrease in average occupancy.

The increase in realized annual rent per occupied square foot in 2025 as compared to 2024 was due to cumulative rate increases to existing long-term tenants over the past twelve months partially offset by a decrease in average rates per square foot charged to new tenants moving in over the same period.

The weighted average square foot occupancy for our Same Store Facilities was 92.0% for 2025, representing a decrease of 0.4%, as compared to 2024, due to softening of demand. In response, we lowered move-in rental rates to stimulate move-in activity at our facilities in 2025 as compared to 2024.

Move-out activities from our tenants were lower in 2025 as compared to 2024. More than half of our tenants have rented their space for longer than a year at December 31, 2025, which supported our revenue growth from existing long-term tenants.

Comparison of the Year Ended December 31, 2024 to the Year Ended December 31, 2023

Revenues generated by our Same Store Facilities decreased 0.6% in 2024 as compared to 2023, due primarily to a 0.5% decrease in average occupancy.

The weighted average square foot occupancy for our Same Store Facilities was 92.4% for 2024, representing a decrease of 0.5%, as compared to 2023, due to softening customer demand. In response, we lowered move-in rental rates and increased advertising spending to stimulate move-in activity at our facilities in 2024 as compared to 2023.

Move-out activities from our tenants were lower in 2024 as compared to 2023. More than half of our tenants have rented their space for longer than a year at December 31, 2024, which supported our revenue growth from existing long-term tenants.

Selected Key Move-in and Move-Out Statistical Data

The following table sets forth average annual contract rent per square foot and total square footage for tenants moving in and moving out during the years ended December 31, 2025, 2024, and 2023. Contract rents gained from move-ins and contracts rents lost from move-outs included in the table assume move-in and move-out activities occur at the beginning of each period presented. The table also includes promotional discounts, which vary based upon the move-in contractual rates, move-in volume, and percentage of tenants moving in who receive the discount.

(Amounts in thousands, except for per square foot amounts)

Tenants moving in during the period:

Tenants moving out during the period:

We expect industry-wide demand from new tenants in 2026 to be similar to 2025, across a diverse set of markets, subject to potential adverse effects from evolving political and macroeconomic uncertainty, including changes in trade policy and new tariffs, pricing restrictions and microeconomic uncertainty. As a result, we expect Same Store Facilities revenues in 2026 to be modestly below those earned in 2025.

Late Charges and Administrative Fees

Late charges and administrative fees decreased 1.0% in 2025 and increased 0.7% in 2024, respectively, in each case as compared to the previous year. The decrease in 2025 was due primarily to lower late charges on delinquent accounts due to lower customer delinquency rates. The increase in 2024 was due primarily to higher late charges and lien fees collected on delinquent accounts.

Analysis of Same Store Cost of Operations

Cost of operations (excluding depreciation and amortization) increased 1.8% and 2.1% in 2025 and 2024, respectively, in each case as compared to the previous year. The increase in 2025 was due primarily to increased property tax expense and indirect cost of operations, partially offset by decreased on-site property manager payroll expense and marketing expense. The increase in 2024 was due primarily to increased property tax expense, repairs and maintenance expense and marketing expense partially offset by decreased on-site property manager payroll expense, utilities expense and indirect cost of operations.

Property tax expense increased 5.3% and 4.8% in 2025 and 2024, respectively, in each case as compared to the previous year, as a result of higher assessed values. We expect property tax expense to grow in 2026 due primarily to higher assessed values.

On-site property manager payroll expense decreased 5.0% and 3.3% in 2025 and 2024, respectively, in each case as compared to the previous year. The decreases in each year were primarily due to reduction in labor hours driven by the continued implementation of dynamic staffing models based on customer activity levels. We expect on-site property manager payroll expense to decrease in 2026 as compared to 2025 as we continue to enhance operational processes.

Repairs and maintenance expense increased 1.4% and 8.8% in 2025 and 2024, respectively, in each case as compared to the previous year. Repairs and maintenance expense levels are dependent upon many factors such as (i) damage and equipment malfunctions, (ii) short-term local supply and demand factors for material and labor, and (iii) weather conditions, which can impact costs such as snow removal, roof repairs, and HVAC maintenance and repairs.

Our utility expense consists primarily of electricity costs, which are dependent upon energy prices and usage levels. Changes in usage levels are driven primarily by weather and temperature. Utility expense increased 1.0% in 2025 and decreased 4.2% in 2024 as compared to the previous year, due primarily to our investment in energy saving technology such as solar power and LED lights, which generate favorable returns on investment in the form of lower utility usage, partially offset by increased utility rates in 2025. We expect lower electricity consumption in 2026 as a result of our continued investment in solar power.

Marketing expense includes internet advertising we utilize through our online paid search programs and the operating costs of our website and telephone reservation center. Internet advertising expense, comprising keyword search fees assessed on a “per click” basis, varies based upon demand for self-storage space, the quantity of people inquiring about self-storage through online search, occupancy levels, the number and aggressiveness of bidding competitors, and other factors. These factors are volatile; accordingly, internet advertising can increase or decrease significantly in the short-term. Our marketing expense decreased by 4.4% in 2025 and increased by 13.1% in 2024 as compared to the previous year. The decrease in 2025 was primarily due to realized cost efficiencies on our online paid search programs utilized to attract new tenants. The increase in 2024 was primarily due to utilizing a higher volume of online paid search programs to attract new tenants. We plan to continue to use internet advertising and other advertising channels to support move-in volumes in 2026.

Indirect Cost of Operations represents costs related to our supervisory payroll, centralized management costs, and share-based compensation. Indirect Cost of Operations increased 6.0% in 2025 and decreased 6.4% in 2024 as compared to the previous year primarily related to changes in the administrative and cash compensation expenses for shared general corporate functions to the extent their efforts are devoted to self-storage operations. Such functions include information technology support, hardware, and software, as well as centralized administration of payroll, benefits, training, repairs and maintenance, customer service, pricing and marketing, operational accounting and finance, legal costs, and costs from field management executives. The increase in 2025 was primarily driven by increases in personnel-related costs. The decrease in 2024 was primarily driven by achievement of economies of scale from recent acquisitions with centralized management costs allocated over a broader number of self-storage facilities including Non-Same Store Facilities.

(d)We have completed the expansion project on a facility acquired in 2023 for $6.9 million, adding 45,000 net rentable square feet of storage space as of December 31, 2025.

(e)The amount includes the costs allocated to land, buildings and intangible assets associated with the 127 self-storage facilities from the Simply (as defined below) acquisition.

We have been active in acquiring facilities in recent years. Since the beginning of 2023, we acquired a total of 273 facilities with 19.9 million net rentable square feet for $3.9 billion. During 2025, these facilities contributed net operating income of $167.5 million.

During 2023, we acquired BREIT Simply Storage LLC (“Simply”), a self-storage company that owned and operated 127 self-storage facilities (9.4 million square feet) and managed 25 self-storage facilities (1.8 million square feet) for third parties, for a purchase price of $2.2 billion in cash.

We remain active in seeking to acquire additional self-storage facilities. Future acquisition volume may be impacted by cost of capital and overall macro-economic uncertainties. During 2025, we acquired 87 self-storage facilities across 21 states with 6.1 million net rentable square feet for $945.6 million. Subsequent to December 31, 2025, we acquired or were under contract to acquire three self-storage facilities across three states with 0.2 million net rentable square feet for $20.7 million. Our total acquisitions planned or completed through December 31, 2025, amount to $966.3 million.

Newly Developed and Expanded Facilities

The Newly Developed and Expanded Facilities include 47 facilities that were developed on new sites since January 1, 2020, and 64 facilities expanded to increase their net rentable square footage. Of these expansions, 45 were completed before 2024, 14 were completed in 2024 or 2025, and five are currently in process at December 31, 2025.

(e)We have completed an expansion project on a facility developed in 2023 for $23.8 million, adding 140,000 net rentable square feet of storage space as of December 31, 2025.

(f)These amounts only include the direct cost incurred to expand and renovate these facilities, and do not include (i) the original cost to develop or acquire the facility or (ii) the lost revenue on space demolished during the construction and fill-up period.

Our Newly Developed and Expanded Facilities includes a total of 111 self-storage facilities of 13.3 million net rentable square feet. For development and expansions completed by December 31, 2025, we incurred a total cost of $1.7 billion. During 2025, Newly Developed and Expanded Facilities contributed net operating income of $124.6 million.

It typically takes at least three to four years for a newly developed or expanded self-storage facility to stabilize with respect to revenues. Physical occupancy can be achieved as early as two to three years following completion of the development or expansion through offering lower rental rates during fill-up. As a result, even after achieving high occupancy, there can still be a period of elevated revenue growth as the tenant base matures and higher rental rates are achieved.

We believe that our development and redevelopment activities generate favorable risk-adjusted returns over the long run. However, in the short run, our earnings are diluted during the construction and stabilization period due to the cost of capital to fund the development cost, the related construction and development overhead expenses included in general and administrative expense, and the net operating loss from newly developed facilities undergoing fill-up.

We typically underwrite new developments to stabilize at approximately an 8% yield on cost (adjusted for impacts from tenant reinsurance and maintenance capital expenditures). Our developed facilities have thus far leased up as expected and are at various stages of their revenue stabilization periods. The actual annualized yields that we may achieve on these facilities upon stabilization will depend on many factors, including local and current market conditions in the vicinity of each property and the level of new and existing supply.

The facilities under “expansions completed” represent those facilities where the expansions have been completed at December 31, 2025. We incurred a total of $809.9 million in direct cost to expand these facilities, demolished a total of 0.6 million net rentable square feet of storage space, and built a total of 4.8 million net rentable square feet of new storage space.

The facilities under “expansion in process” represent those facilities where construction is in process at December 31, 2025, and together with additional future expansion activities primarily related to our Same Store Facilities at December 31, 2025, we expect to add a total of 0.9 million net rentable square feet of storage space by expanding existing self-storage facilities for an aggregate direct development cost of $130.4 million.

At December 31, 2025, we had 29 additional facilities in development, which will have a total of 2.6 million net rentable square feet of storage space and have an aggregate development cost totaling approximately $479.5 million. We expect these facilities to open over the next 18 to 24 months.

As of December 31, 2025, we have ongoing development and expansion projects at an estimated cost of approximately $609.9 million.

Other Non-Same Store Facilities

The “Other Non-Same Store Facilities” represent facilities which, while not newly acquired, developed, or expanded, are not fully stabilized since January 1, 2023, including facilities acquired prior to 2023 and facilities developed or expanded prior to 2020 undergoing fill-up as well as facilities damaged in casualty events such as hurricanes, floods, and fires.

The Other Non-Same Store Facilities have an aggregate of 20.9 million net rentable square feet at December 31, 2025. During 2025, 2024, and 2023, the average occupancy for these facilities totaled 85.3%, 81.8%, and 80.8%, respectively, and the realized rent per occupied square foot totaled $15.82, $16.01, and $15.52, respectively.

Depreciation and amortization expense

Depreciation and amortization expense for Self-Storage Operations increased $22.1 million and $159.7 million in 2025 and 2024, respectively in each case as compared to the previous year. The increase was primarily due to newly acquired facilities and newly developed and expanded facilities.

The following discussion and analysis of the components of net income, including Ancillary Operations and certain items not allocated to segments, present a comparison for the year ended December 31, 2025 to the year ended December 31, 2024. The results of these components for the years ended December 31, 2024 compared to December 31, 2023 was included in our Annual Report on Form 10-K for the year ended December 31, 2024 on page 45, under Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which was filed with the SEC on February 24, 2025.

Ancillary Operations

Ancillary revenues and expenses include amounts associated with the reinsurance of policies against losses to goods stored by tenants in our self-storage facilities, sale of merchandise at our self-storage facilities, and management of property owned by unrelated third parties. The following table sets forth our ancillary operations:

Year Ended December 31,

(Amounts in thousands)

Revenues:

Cost of operations:

Net operating income (loss):

Tenant reinsurance operations: Tenant reinsurance premium revenue increased $24.1 million or 10.6% in 2025 over 2024, as a result of an increase in our tenant base with respect to acquired, newly developed, and expanded facilities and the third party properties we manage, as well as higher insurance coverage and premium rates in our tenant base at our same store facilities. Tenant reinsurance premium revenue generated from tenants at our Same Store Facilities were $184.2 million and $175.0 million in 2025 and 2024, respectively, representing a 5.2% year over year increase in 2025.

Cost of operations primarily includes claims paid as well as claims adjustment expenses. Claims expenses vary based upon the number of insured tenants and the volume of events that drive covered losses, such as burglary, as well as catastrophic weather events affecting multiple properties such as hurricanes and floods. Tenant reinsurance cost of operations increased $1.6 million in 2025, as compared to 2024, primarily due to increased claim volumes and expenses related to flooding and burglary as well as increased access fees we paid to the third-party owners of properties we manage driven by the significant growth of our third-party property management program.

We expect tenant reinsurance operations to grow as we roll out insurance policies with increased coverage and higher premiums in 2026, and as we continue to increase the tenant base at our newly acquired and developed facilities.

Third-party property management: At December 31, 2025, in our third-party property management program, we managed 362 facilities (28.2 million net rentable square feet) for unrelated third parties, and were under contract to manage 84 additional facilities (7.1 million net rentable square feet) including 78 facilities that are currently under construction. During 2025, we added 73 facilities to the program and had 18 facilities exit the program. While we expect this business to increase in scope and size, we do not expect any significant changes in overall profitability of this business in the near term as we seek new properties to manage and are in the earlier stages of fill-up for newly managed properties.

Analysis of items not allocated to segments

Equity in earnings of unconsolidated real estate entity: We account for our equity investment in Shurgard using the equity method and record our pro-rata share of its net income. We recognized equity in earnings of Shurgard of $9.6 million and $19.8 million for 2025 and 2024, respectively. Included in our equity earnings from Shurgard were $59.5 million and $44.2 million of our share of depreciation and amortization expense for 2025 and 2024, respectively.

On August 1, 2024, Shurgard acquired Lok’nStore, a self-storage company publicly traded on the London Stock Exchange, for approximately £385 million ($501 million) in cash, including direct acquisition costs.

For purposes of recording our equity in earnings from Shurgard, the Euro was translated at exchange rates of approximately 1.174 U.S. Dollars per Euro at December 31, 2025 (1.039 at December 31, 2024), and average exchange rates of 1.130 for 2025 and 1.082 for 2024.

Real estate acquisition and development expense: In 2025 and 2024, we incurred a total of $19.6 million and $15.5 million, respectively, of internal and external expenses related to our acquisition and development of real estate facilities. These amounts are net of $13.6 million and $17.2 million in 2025 and 2024, respectively, in development costs that were capitalized to newly developed and redeveloped self-storage facilities. The year-over-year change of real estate acquisition and development expense was primarily due to the recognition of a $4.3 million impairment write-down of certain land development parcels that were marketed for sale during 2025.

General and administrative expense: The following table sets forth our general and administrative expense:

Year Ended December 31,

(Amounts in thousands)

Corporate transformation costs 4,875 — 4,875

General and administrative expense remained relatively unchanged in 2025, as compared to 2024 due primarily to (i) an increase in corporate management costs driven by higher payroll costs, (ii) an increase in corporate transformation costs offset by (iii) a decrease in IT costs as a result of a successful ERP implementation in the prior year.

As part of our operating model transformation, we have launched a corporate transformation initiative focused on modernization and growth. This includes streamlining our processes through technology and expanding our geographic footprint with a stronger corporate presence in offshore locations and relocation of our principal office from California to Texas. The initiative is intended to transform our corporate functions improving efficiency and productivity.

We expect to incur corporate transformation costs of approximately $15 to $20 million as we complete the initiative over the next three years. Beginning in 2026, we believe this restructuring plan will result in future cost savings of approximately $3 to $5 million annually, although the amount and timing of such savings are subject to change depending on a variety of factors.

Interest and other income: The following table sets forth our interest and other income:

Year Ended December 31,

(Amounts in thousands)

Interest earned on notes receivable, net 5,074 123 4,951

Unrealized gain on private equity investments 3,859 4,355 (496)

Interest earned on cash balances decreased $13.1 million in 2025 as compared to 2024, due primarily to lower average cash balances and lower interest rates earned in 2025.

Interest expense: In 2025 and 2024, we incurred $311.0 million and $297.9 million, respectively, of interest on our outstanding notes payable. In determining interest expense, these amounts were offset by capitalized interest of $6.5 million and $10.5 million during 2025 and 2024, respectively, associated with our development activities. The increase of interest expense in 2025 as compared to 2024 was due to the issuance of U.S. Dollar and Euro denominated unsecured notes. At December 31, 2025, we had $10.3 billion of notes payable outstanding, with a weighted average interest rate of approximately 3.2%.

Foreign currency exchange gain (loss): In 2025, we recorded foreign currency losses of $215.6 million, representing primarily the changes in the U.S. Dollar equivalent of our Euro-denominated unsecured notes due to fluctuations in exchange rates (gains of $102.2 million for 2024). The Euro was translated at exchange rates of approximately 1.174 U.S. Dollars per Euro at December 31, 2025 and 1.039 at December 31, 2024. Future gains and losses on foreign currency will be dependent upon changes in the relative value of the Euro to the U.S. Dollar and the level of Euro-denominated notes payable outstanding.

Income tax (provision) benefit: We operate as a REIT for U.S. federal income tax purposes. As a REIT, we are generally not subject to U.S. federal income taxes on our taxable income distributed to stockholders. In 2025, we recorded an income tax benefit of $7.2 million and an income tax expense of $4.7 million in 2024, related to our taxable REIT subsidiaries and income taxes incurred in certain state and local jurisdictions in which we operate. The year-over-year change in our income tax (provision) benefit was primarily driven by the income tax benefit we recognized through the sale of solar tax credits as well as changes in state income tax, due to fluctuations of taxable income in certain states where there are differences between federal and state tax laws.

Liquidity and Capital Resources

Overview and our Sources of Capital

While operating as a REIT allows us to minimize the payment of U.S. federal corporate income tax expense, we are required to distribute at least 90% of our taxable income to our shareholders. Notwithstanding this requirement, our annual operating retained cash flow was approximately $400 million in 2024 and $566 million in 2025. Retained operating cash flow represents our expected cash flow provided by operating activities (including property operating costs and interest payments described below), less shareholder distributions and capital expenditures. We expect retained cash flow of approximately $605 million for 2026.

Capital needs in excess of retained cash flow are met with: (i) medium and long-term debt, (ii) preferred equity, (iii) limited partnership interests, and (iv) common equity. We select among these sources of capital based upon relative cost, availability, the desire for leverage, and considering potential constraints caused by certain features of capital sources, such as debt covenants.

Because raising capital is important to our growth, we endeavor to maintain a strong financial profile characterized by strong credit metrics, including low leverage relative to our total capitalization and operating cash flows. We are one of the highest rated REITs, as rated by major rating agencies Moody’s and Standard & Poor’s. Our senior notes payable have an “A” credit rating by Standard & Poor’s and “A2” by Moody’s. Our credit ratings on each of our series of preferred shares are “A3” by Moody’s and “BBB+” by Standard & Poor’s. Our credit profile enables us to effectively access both the public and private capital markets to raise capital.

Our revolving line of credit has a borrowing limit of $1.5 billion. As of December 31, 2025 and February 12, 2026, there were no borrowings outstanding on the revolving line of credit; however we do have approximately $19.4 million of outstanding letters of credit, which limits our borrowing capacity to $1.5 billion as of February 12, 2026. Our line of credit matures on June 12, 2027.

In December 2024, we implemented an “at the market” offering program pursuant to which we may, from time to time, sell common shares through participating agents up to an aggregate gross sales price of $2.0 billion on the open market or in privately negotiated transactions. Since the inception of the program, we have issued a total of 184,390 common shares on the open market for an aggregate gross sales price of $61.4 million and received net proceeds of approximately $60.3 million after issuance costs. We did not issue any common shares under the program in 2025.

We believe that we have significant financial flexibility to adapt to changing conditions and opportunities, and we have significant access to sources of capital including debt and preferred equity. Based on our strong credit profile and our substantial current liquidity relative to our capital requirements noted below, we would not expect any potential capital market dislocations to have a material impact upon our expected capital and growth plans over the next 12 months. However, if capital market conditions deteriorate significantly for a long period of time, our access to or cost of debt and preferred equity capital could be negatively impacted and potentially affect future investment activities.

Our current and expected capital resources include: (i) $318.1 million of cash as of December 31, 2025, and (ii) approximately $605 million of expected retained operating cash flow over the next twelve months. Additionally, we have $1.5 billion available borrowing capacity on our revolving line of credit. We believe that the cash provided by our operating activities will continue to be sufficient to enable us to meet our ongoing cash requirements for interest payments on debt, maintenance capital expenditures, and distributions to our shareholders for the foreseeable future.

As described below, our current committed cash requirements consist of (i) $20.7 million in property acquisitions currently under contract, (ii) $415.6 million of remaining spending on our current development pipeline, which will be incurred primarily in the next 18 to 24 months, (iii) unfunded loan commitments of $43.9 million under the bridge lending program expected to close in the next twelve months, (iv) approximately $1.2 billion in scheduled principal repayments on our unsecured notes in the next twelve months, and (v) $48.2 million in unfunded capital commitments related to our private equity investments. We plan to refinance these unsecured notes as they come due in 2026 through either cash generated from operations, the issuance of additional debt or borrowings under the Company's Credit Facility. Our cash requirements may increase over the next year as we add projects to our development pipeline and acquire additional properties. Additional potential cash requirements could result from various activities including the redemption of outstanding preferred securities, repurchases of common stock, or merger and acquisition activities, as and to the extent we determine to engage in such activities.

Over the long term, to the extent that our cash requirements exceed our capital resources, we believe we have a variety of possibilities to raise additional capital including issuing common or preferred securities, debt, and limited partnership interests, or entering into joint venture arrangements to acquire or develop facilities.

Cash Requirements

The following summarizes our expected material cash requirements, which comprise (i) contractually obligated expenditures, including payments of principal and interest, (ii) other essential expenditures, including property operating expenses, maintenance capital expenditures and dividends paid in accordance with REIT distribution requirements, and (iii) opportunistic expenditures, including acquisitions and developments and repurchases of our securities. We expect to satisfy these cash requirements through operating cash flow and opportunistic debt and equity financings.

Required Debt Repayments:As of December 31, 2025, the principal outstanding on our debt totaled approximately $10.3 billion, consisting of $8.2 billion of U.S. Dollar denominated unsecured notes payable, $2.1 billion of Euro-denominated unsecured notes payable, and $1.6 million of mortgage notes payable. Approximate principal maturities and interest payments are as follows:

Principal Interest Total

(Amounts in Thousands)

We have $500 million and $650 million of our U.S. Dollar denominated unsecured notes that mature on February 15, 2026 and November 9, 2026, respectively. We plan to repay these notes as they come due through either cash generated from operations or the issuance of additional debt, such as borrowings under the Company's Credit Facility.

Capital Expenditure Requirements: Capital expenditures include general maintenance, major repairs, or replacements to elements of our facilities to keep our facilities in good operating condition and maintain their visual appeal. Capital expenditures do not include costs relating to the development of new facilities or redevelopment of existing facilities to increase their available rentable square footage.

We spent $218 million of capital expenditures to maintain real estate facilities in 2025 and expect to spend approximately $175 million in 2026. In addition, we have spent $71 million and $54 million on the installation of solar panels in 2025 and 2024, respectively, and expect to spend approximately $60 million in 2026.

We believe the capital spent to install solar panels and LED lights will significantly reduce electricity consumption resulting in lower utility costs.

Requirement to Pay Distributions: For all periods presented herein, we have elected to be treated as a REIT, as defined in the Internal Revenue Code. For each taxable year in which we qualify for taxation as a REIT, we will not be subject to U.S. federal corporate income tax on our “REIT taxable income” (generally, taxable income subject to specified adjustments, including a deduction for dividends paid and excluding our net capital gain) that is distributed to our shareholders. We believe we have met these requirements in all periods presented herein, and we expect to continue to qualify as a REIT.Our consistent, long-term dividend policy has been to distribute our taxable income. Future quarterly distributions with respect to the common shares will continue to be determined based upon our REIT distribution requirements after taking into consideration distributions to the preferred shareholders and will be funded with cash flows from operating activities.

The annual distribution requirement with respect to our preferred shares outstanding at December 31, 2025 is approximately $194.7 million per year.

Real Estate Investment Activities:We continue to seek to acquire additional self-storage facilities from third parties. Subsequent to December 31, 2025, we acquired or were under contract to acquire three self-storage facilities across three states with 0.2 million net rentable square feet for $20.7 million.

As of December 31, 2025, we had development and expansion projects at a total cost of approximately $609.9 million. Costs incurred through December 31, 2025 were $194.3 million, with the remaining cost to complete of $415.6 million expected to be incurred primarily in the next 18 to 24 months. Some of these projects are subject to contingencies such as entitlement approval. We expect to continue to seek to add projects to maintain and increase our robust pipeline. Our ability to do so continues to be challenged by various constraints such as difficulty in finding projects that meet our risk-adjusted yield expectations and challenges in obtaining building permits for self-storage facilities in certain municipalities.

Bridge loan commitments: We offer bridge loan financing to third-party self-storage owners for operating properties that we manage. As of December 31, 2025, we had unfunded loan commitments of $43.9 million expected to close in the next twelve months, subject to the satisfaction of certain conditions.

Property Operating Expenses: The direct and indirect cost of our operations impose significant cash requirements. Direct operating costs include property taxes, on-site property manager payroll, repairs and maintenance, utilities, and marketing. Indirect operating costs include supervisory payroll and centralized management costs. The cash requirements from these operating costs will vary year to year based on, among other things, changes in the size of our portfolio and changes in property tax rates and assessed values, wage rates, and marketing costs in our markets.

Redemption of Preferred Securities: Historically, we have taken advantage of refinancing higher coupon preferred securities with lower coupon preferred securities. In the future, we may also elect to finance the redemption of preferred securities with proceeds from the issuance of debt. As of February 12, 2026, our Series F through O of preferred securities are eligible for redemption, at our option and with 30 days’ notice. See Note 10 to our December 31, 2025 consolidated financial statements for the redemption dates of all of our series of preferred shares. Redemption of such preferred shares will depend upon many factors, including the rate at which we could issue replacement preferred securities. None of our preferred securities are redeemable at the option of the holders.

Repurchases of Common Shares: Our Board has authorized a share repurchase program pursuant to which management may purchase up to 35,000,000 of our common shares on the open market or in privately negotiated transactions. From the inception of the repurchase program through February 12, 2026, we have repurchased a total of 24,448,781 common shares at an aggregate cost of approximately $879.1 million. We did not repurchase any common shares in 2025. All the repurchased shares are constructively retired and returned to an authorized and unissued status. Future levels of common share repurchases will be dependent upon our available capital, investment alternatives and the trading price of our common shares.

Recent Tax Legislation

Effective July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law. Certain provisions of OBBBA impact us and our shareholders. Among other changes, this legislation (i) permanently extended the 20% deduction for “qualified REIT dividends” for individuals and other non-corporate taxpayers under Section 199A of the Internal Revenue Code (“the Code”), (ii) permanently reinstates 100% bonus depreciation for certain property acquired after January 19, 2025, (iii) increased the percentage limit under the REIT asset test applicable to taxable REIT subsidiaries (“TRSs”) from 20% to 25% for taxable years beginning after December 31, 2025, and (iv) increases the base on which the 30% interest deduction limit under Section 163(j) of the Code applies by excluding depreciation, amortization and depletion from the definition of “adjusted taxable income” (i.e. based on EBITDA rather than EBIT) for taxable years beginning after December 31, 2024.

ITEM 7A.Quantitative and Qualitative Disclosures about Market Risk

To limit our exposure to market risk, we are capitalized primarily with preferred and common equity. Our preferred shares are redeemable at our option generally five years after issuance, but the holder has no redemption option. Our debt, which totals approximately $10.3 billion at December 31, 2025, is the only market-risk sensitive portion of our capital structure.

The fair value of our debt at December 31, 2025 is approximately $9.9 billion. The table below summarizes the annual maturities of our debt, which had a weighted average effective rate of 3.2% at December 31, 2025. See Note 8 to our December 31, 2025 consolidated financial statements for further information regarding our debt.

(Amounts in Thousands)

At December 31, 2025, we have three separate interest rate swaps with a notional amount of $475 million which converted our $475 million principal amount of 4.375% fixed rate senior unsecured notes due July 2030 into a floating rate instrument with an interest rate based on a SOFR index. See Note 8 to our December 31, 2025 consolidated financial statements for further information regarding our swaps.

We have foreign currency exposure at December 31, 2025 related to (i) our investment in Shurgard, with a book value of $388.6 million, and a fair value of $1.2 billion based upon the closing price of Shurgard’s stock on December 31, 2025, and (ii) €1.8 billion ($2.1 billion) of Euro-denominated unsecured notes payable, providing a natural hedge against the fair value of our investment in Shurgard.

ITEM 9A. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in reports we file and submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized, and reported within the time periods specified in accordance with SEC guidelines, and that such information is communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure based on the definition “of disclosure controls and procedures” in Rules 13a-15(e) and 15d-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 provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures in reaching that level of reasonable assurance. We also have an investment in an unconsolidated real estate entity, and, because we do not control this entity, our disclosure controls and procedures with respect to such entity are substantially more limited than those we maintain with respect to our consolidated subsidiaries.

As of December 31, 2025, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2025, at a reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee on Sponsoring Organizations of the Treadway Commission (2013 Framework). Based on our evaluation under the framework in Internal Control-Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of internal control over financial reporting as of December 31, 2025, has been audited by Ernst & Young LLP, an independent registered public accounting firm. Ernst & Young LLP’s report on our internal control over financial reporting appears below.

Changes in Internal Control Over Financial Reporting

There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of 2025 to which this report relates that have materially affected, or are reasonable likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of Public Storage

Opinion on Internal Control Over Financial Reporting

We have audited Public Storage’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Public Storage (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2025 and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 12, 2026 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 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. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of Public Storage

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Public Storage (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2025 , and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 12, 2026 expressed an unqualified opinion thereon.

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 PCAOB and are required to be independent with respect to the Company in accordance with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. 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 Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2025

1. Description of the Business

Public Storage is a Maryland real estate investment trust (“REIT”) engaged in the ownership and operation of self-storage facilities that offer storage spaces for lease, generally on a month-to-month basis, for personal and business use, and other related operations such as tenant reinsurance, merchandise sales, third party management, and bridge lending to third-party self-storage owners, as well as the acquisition and development of additional self-storage space.

We are structured as an umbrella partnership REIT, or UPREIT, under which substantially all of our business is conducted through Public Storage OP, L.P. (“PSA OP”), an operating partnership, and its subsidiaries, including Public Storage Operating Company (“PSOC”). The primary assets of the parent entity, Public Storage, are general partner and limited partner interests in PSA OP, which holds all of the Company’s assets through its ownership of all of the equity interests in PSOC. As a limited partnership, PSA OP is a variable interest entity and is consolidated by Public Storage as its primary beneficiary. As of December 31, 2025, Public Storage owned all of the general partner interests and approximately 99.80% of the limited partnership interests of PSA OP, with the remaining 0.20% of limited partnership interests owned by certain trustees and officers of the Company.

Unless stated otherwise or the context otherwise requires, references to “Public Storage” mean the parent entity, Public Storage, and references to “the Company,” “we,” “us,” and “our” mean collectively Public Storage, PSA OP, PSOC, and those entities/subsidiaries owned or controlled by Public Storage, PSA OP, and PSOC.

At December 31, 2025, we owned interests in 3,171 self-storage facilities (with approximately 229.4 million net rentable square feet) located in 40 states in the United States (“U.S.”) operating under the Public Storage® name, and 1.0 million net rentable square feet of commercial and retail space. In addition, we managed 362 facilities (with approximately 28.2 million net rentable square feet) for third parties at December 31, 2025.

At December 31, 2025, we owned an approximate 35% common equity interest in Shurgard Self Storage Limited (“Shurgard”), a public company traded on the Euronext Brussels under the “SHUR” symbol, which owned 332 self-storage facilities (with approximately 18 million net rentable square feet) located in seven Western European countries, all operating under the Shurgard® name. In recording our share of equity in earnings or loss from Shurgard, we adjust Shurgard’s operating results, which are reported under International Financial Reporting Standards (“IFRS”), to conform with U.S. generally accepted accounting principles (“GAAP”).

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

We have prepared the accompanying consolidated financial statements in accordance with U.S. GAAP as set forth in the Accounting Standards Codification of the Financial Accounting Standards Board, and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”).

Disclosures of the number and square footage of facilities, as well as the number and coverage of tenant reinsurance policies (Note 16) are unaudited and outside the scope of our independent registered public accounting firm’s audit of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.).

PUBLIC STORAGE

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2025

Summary of Significant Accounting Policies

Consolidation and Equity Method of Accounting

We consider entities to be Variable Interest Entities (“VIEs”) when they have insufficient equity to finance their activities without additional subordinated financial support provided by other parties, or the equity holders as a group do not have a controlling financial interest. In addition, we have general partner interests in limited partnerships along with third-party investors to develop, construct or operate self-storage facilities. As the general partner, we consider the limited partnerships to be VIEs if the limited partners lack both substantive participating rights and substantive kick-out rights. We consolidate VIEs when we have (i) the power to direct the activities most significantly impacting economic performance, and (ii) either the obligation to absorb losses or the right to receive benefits from the VIE. PSA OP met the definition of a VIE and is consolidated by the Company as the primary beneficiary of PSA OP. All of the assets and liabilities of the Company are held by PSA OP. The total assets, primarily real estate assets, and the total liabilities of our other consolidated VIEs are not material as of December 31, 2025. We consolidate all other entities when we control them through voting shares or contractual rights. We refer to the entities we consolidate, for the period in which the reference applies, collectively as the “Subsidiaries,” and we eliminate intercompany transactions and balances.

We account for our investment in an entity that we do not consolidate but over which we have significant influence using the equity method of accounting. We refer to this entity, for the periods in which the reference applies, as the “Unconsolidated Real Estate Entity,” and we eliminate intra-entity profits and losses and amortize any differences between the cost of our investment and the underlying equity in net assets against equity in earnings as if the Unconsolidated Real Estate Entity was a consolidated subsidiary.

Equity in earnings of unconsolidated real estate entity presented on our income statements represents our pro-rata share of the earnings of the Unconsolidated Real Estate Entity. The dividends we receive from the Unconsolidated Real Estate Entity are reflected on our consolidated statements of cash flows as “distributions from cumulative equity in earnings of unconsolidated real estate entity” to the extent of our cumulative equity in earnings, with any excess classified as “distributions in excess of cumulative equity in earnings from unconsolidated real estate entity.”

Use of Estimates

The preparation of consolidated financial statements and accompanying notes in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates and assumptions.

Cash Equivalents

Cash equivalents represent highly liquid financial instruments that mature within three months of acquisition such as money market funds with a rating of at least AAA by Standard & Poor’s, commercial paper that is rated A1 by Standard & Poor’s or deposits with highly rated commercial banks.

Fair Value

As used herein, the term “fair value” is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. In the absence of active markets for identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information that is consistent with what market participants would use in a hypothetical transaction that occurs at the balance sheet date.

Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

Level 1 Quoted prices in active markets for identical assets or liabilities at the measurement date.

F-11

PUBLIC STORAGE

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2025

Level 2 Significant observable inputs other than Level 1, that are observable for the asset or liability, either directly or indirectly through corroboration with observable market data.

Level 3 Unobservable inputs that are supported by little or no market data for the related assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Our financial instruments consist of cash and cash equivalents, notes receivable, other assets, other liabilities, and notes payable and related interest rate swaps. Cash equivalents, notes receivable, other assets and other liabilities are stated at book value, which approximates fair value as of the balance sheet date due to the short time period to maturity or variable interest rates.

We estimate and disclose the fair value of our notes payable and related interest rate swaps using Level 2 inputs by discounting the related future cash flows at a rate based upon quoted interest rates for securities that have similar characteristics such as credit quality and time to maturity.

We use significant judgment to estimate fair values of real estate facilities, goodwill, and other intangible assets for the purposes of purchase price allocation or impairment analysis. In estimating their values, we consider Level 3 inputs such as market prices of land, market capitalization rates, expected returns, earnings multiples, projected levels of earnings, costs of construction, and functional depreciation.

Real Estate Facilities

We record real estate facilities at cost. We capitalize all costs incurred to acquire, develop, construct, renovate and improve facilities as part of major repair and maintenance programs, including interest and property taxes incurred during the construction period. We expense the costs of demolition of existing facilities associated with a renovation as incurred. We allocate the net acquisition cost of acquired real estate facilities to the underlying land, buildings, and identified intangible assets based upon their respective individual estimated fair values.

We expense costs associated with dispositions of real estate, as well as routine repairs and maintenance costs, as incurred. We depreciate buildings and improvements on a straight-line basis over estimated useful lives ranging generally between 5 to 40 years.

When we sell a full or partial interest in a real estate facility without retaining a controlling interest following sale, we recognize a gain or loss on sale as if 100% of the property was sold at fair value. If we retain a controlling interest following the sale, we record a noncontrolling interest for the book value of the partial interest sold, and recognize additional paid-in capital for the difference between the consideration received and the partial interest at book value.

Goodwill and Other Intangible Assets

Intangible assets consist of goodwill, the Shurgard® trade name, which Shurgard uses pursuant to a fee-based licensing agreement, and finite-lived assets. Goodwill and the Shurgard® trade name have indefinite lives and are not amortized. Our finite-lived assets consist primarily of (i) acquired customers in place amortized relative to the benefit of the customers in place, with such amortization reflected as depreciation and amortization expense on our income statement, (ii) property tax abatements acquired and amortized relative to the reduction in property tax paid, with such amortization reflected as self-storage cost of operations on our income statement and (iii) acquired non real estate-related contracts, with such amortization reflected as depreciation and amortization expense on our income statement.

F-12

PUBLIC STORAGE

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2025

Notes Receivable

We account for notes receivable from bridge loans we originate to third-party self-storage owners at amortized cost. The bridge loans, collateralized by operating self-storage properties, typically have a term of three years or four years with twoone-year extensions, and have variable interest rates. We recognize interest income and other fee income related to the bridge loans using the effective interest method, with deferred fees and costs amortized over the lives of the related loans as yield adjustment. We recognize an allowance for expected credit losses for outstanding notes receivable and unfunded loan commitments.

Evaluation of Asset Impairment

We evaluate our real estate and finite-lived intangible assets for impairment each quarter. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal.

We evaluate our investment in unconsolidated real estate entity for impairment quarterly. We record an impairment charge to the extent the carrying amount exceeds estimated fair value, when we believe any such shortfall is other than temporary.

We evaluate goodwill for impairment annually and whenever relevant events, circumstances, and other related factors indicate that it is more likely than not that the fair value of the related reporting unit is less than the carrying amount. When we conclude that it is not more likely than not that the fair value of the reporting unit is less than the aggregate carrying amount, no impairment charge is recorded and no further analysis is performed. Otherwise, we record an impairment charge to the extent the carrying amount of the goodwill exceeds the amount that would be allocated to goodwill if the reporting unit were acquired for estimated fair value.

We evaluate other indefinite-lived intangible assets, such as the Shurgard® trade name for impairment at least annually and whenever relevant events, circumstances and other related factors indicate that it is more likely than not that the asset is impaired. When we conclude that it is not more likely than not that the asset is impaired, we do not record an impairment charge and no further analysis is performed. Otherwise, we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value.

During 2025, we recognized $4.3 million of impairment write-down of certain land development parcels that are or will be marketed for sale. These land development parcels are included in other assets on the Consolidated Balance Sheet, and the related impairment write-down is included in real estate acquisition and development expense on the Consolidated Statements of Income.

Revenue and Expense Recognition

We recognize revenues from self-storage facilities, which primarily comprise rental income earned pursuant to month-to-month leases, as well as associated late charges and administrative fees, as earned. Promotional discounts reduce rental income over the promotional period, which is generally one month. We recognize ancillary revenues when earned.

We accrue for property tax expense based upon actual amounts billed and, in some circumstances, estimates when bills or assessments have not been received from the taxing authorities. If these estimates are incorrect, the timing and amount of expense recognition could be incorrect. We expense cost of operations (including advertising expenditures), general and administrative expense, and interest expense as incurred.

Foreign Currency Exchange Translation

The local currency (the Euro) is the functional currency for our equity interests in Shurgard. The related balance sheet amounts are translated into U.S. Dollars at the exchange rates at the respective financial statement date, while amounts on our consolidated statements of income are translated at the average exchange rates during the respective period. Cumulative translation adjustments, are included in equity as a component of accumulated other comprehensive income (loss).

When financial instruments denominated in a currency other than the U.S. Dollar are expected to be settled in cash in the foreseeable future, the impact of changes in the U.S. Dollar equivalent are reflected in current earnings.

At December 31, 2025, due primarily to our investment in Shurgard (Note 4) and our notes payable denominated in Euros (Note 8), our operating results and financial position are affected by fluctuations in currency exchange rates between the Euro, against the U.S. Dollar. The Euro was translated at exchange rates of approximately 1.174 U.S. Dollars per Euro at December 31, 2025 (1.039 at December 31, 2024), and average exchange rates of 1.130, 1.082 and 1.081 for the years ended December 31, 2025, 2024, and 2023, respectively.

Income Taxes

We and a subsidiary of PSOC have elected to be treated as a REIT, as defined in the Internal Revenue Code of 1986, as amended (the “Code”). For each taxable year in which we qualify for taxation as a REIT, we will not be subject to U.S. federal corporate income tax on our “REIT taxable income” (generally, taxable income subject to specified adjustments, including a deduction for dividends paid and excluding our net capital gain) that is distributed to our shareholders.
