NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2023

(Unaudited)

1.Description of the Business

Public Storage (referred to herein as “the Company,” “we,” “us,” or “our”), a Maryland real estate investment trust that has elected to be taxed as a real estate investment trust (“REIT”), was organized in 1980. Our principal business activities include 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, ancillary activities such as tenant reinsurance, merchandise sales, and third party management, as well as the acquisition and development of additional self-storage space.

At March 31, 2023, we had direct and indirect equity interests in 2,877 self-storage facilities (with approximately 204.9 million net rentable square feet) located in 40 states in the United States (“U.S.”) operating under the Public Storage® name, and 1.2 million net rentable square feet of commercial and retail space.

At March 31, 2023, we owned a 35% common equity interest in Shurgard Self Storage Limited (“Shurgard”), a public company traded on the Euronext Brussels under the “SHUR” symbol, which owned 266 self-storage facilities (with approximately 15 million net rentable square feet) located in seven Western European countries, all operating under the Shurgard® name.

2.Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

We have prepared the accompanying interim consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) as set forth in the Accounting Standards Codification of the Financial Accounting Standards Board (“FASB”), and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”). In our opinion, the interim consolidated financial statements presented herein reflect all adjustments, primarily of a normal recurring nature, that are necessary to present fairly the interim consolidated financial statements. Because they do not include all of the disclosures required by GAAP for complete annual financial statements, these interim consolidated financial statements should be read together with the audited Consolidated Financial Statements and related Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Certain amounts previously reported in our March 31, 2022 Statements of Cash Flows have been reclassified to conform to the March 31, 2023 presentation, with respect to the separate presentation of changes in operating assets and liabilities in the cash flows from operating activities section.

Disclosures of the number and square footage of facilities, as well as the number and coverage of tenant reinsurance policies (Note 14) are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.).

Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

Summary of Significant Accounting Policies

There have been no significant changes to the Company's significant accounting policies described in Note 2, Basis of Presentation and Summary of Significant Accounting Policies, in Notes to Consolidated Financial Statements included in Item 8 of Part II of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

4.Investments in Unconsolidated Real Estate Entities

The following tables set forth our investments in, and equity in earnings of, the Unconsolidated Real Estate Entities (amounts in thousands):

	Investments in Unconsolidated Real Estate Entities at
	March 31, 2023		December 31, 2022
Shurgard	$	285,692	$	275,752

	Equity in Earnings of Unconsolidated Real Estate Entities for the
	Three Months Ended March 31,
	2023		2022
PSB	$	—	$	36,886
Shurgard	5,995		6,538
Total	$	5,995	$	43,424

Investment in PSB

On July 20, 2022, in connection with the closing of the merger of PS Business Parks, Inc. (“PSB”) with affiliates of Blackstone Real Estate (“Blackstone”), we completed the sale of our 41% common equity interest in PSB in its entirety. At the close of the merger transaction, we received a total of $2.7 billion of cash proceeds and recognized a gain of $2.1 billion during the third quarter of 2022.

Since the sale of PSB in July 2022, we no longer recognize equity in earnings or receive cash distributions from PSB. During the three months ended March 31, 2022, we received cash distributions from PSB totaling $15.2 million.

Investment in Shurgard

Throughout all periods presented, we effectively owned, directly and indirectly 31,268,459 Shurgard common shares, representing a 35% equity interest in Shurgard.

Based upon the closing price at March 31, 2023 (€44.10 per share of Shurgard common stock, at 1.088 exchange rate of U.S. Dollars to the Euro), the shares we owned had a market value of approximately $1.5 billion.

Our equity in earnings of Shurgard comprised our equity share of Shurgard’s net income, less amortization of the Shurgard Basis Differential (defined below). During each of the three months ended March 31, 2023 and 2022, we received $0.9 million of trademark license fees that Shurgard pays to us for the use of the Shurgard® trademark. We eliminated $0.3 million of intra-entity profits and losses for each of the three months ended March 31, 2023 and 2022, representing our equity share of the trademark license fees. We classify the remaining license fees we receive from Shurgard as interest and other income on our income statement.

At March 31, 2023, our investment in Shurgard’s real estate assets exceeded our pro-rata share of the underlying amounts on Shurgard’s balance sheet by approximately $63.3 million ($67.8 million at December 31, 2022). This differential (the “Shurgard Basis Differential”) includes our basis adjustments in Shurgard’s real estate assets net of related deferred income taxes. The Shurgard Basis Differential is being amortized as a reduction to equity in earnings of the Unconsolidated Real Estate Entities. Such amortization totaled approximately $4.5 million and $1.3 million during the three months ended March 31, 2023 and 2022, respectively.

As of March 31, 2023 and 2022, we translated the book value of our investment in Shurgard from Euro to U.S. Dollars and recorded $3.9 million other comprehensive income and $6.8 million other comprehensive loss during the three month ended March 31, 2023 and 2022, respectively.

6.Credit Facility

We have a revolving credit agreement (the “Credit Facility”) with a $500 million borrowing limit that matures on April 19, 2024. Amounts drawn on the Credit Facility bear annual interest at rates ranging from LIBOR plus 0.7% to LIBOR plus 1.350% depending upon the ratio of our Total Indebtedness to Gross Asset Value (as defined in the Credit Facility) (LIBOR plus 0.75% at March 31, 2023). We are also required to pay a quarterly facility fee ranging from 0.07% per annum to 0.25% per annum depending upon the ratio of our Total Indebtedness to our Gross Asset Value (0.10% per annum at March 31, 2023). At March 31, 2023 and May 3, 2023, we had no outstanding borrowings under this Credit Facility. We had undrawn standby letters of credit, which reduce our borrowing capacity, totaling $18.6 million at March 31, 2023 ($18.6 million at December 31, 2022). The Credit Facility has various customary restrictive covenants with which we were in compliance at March 31, 2023.

U.S. Dollar Denominated Unsecured Notes

The U.S. Dollar denominated unsecured notes (the “U.S. Dollar Denominated Unsecured Notes”) have various financial covenants with which we were in compliance at March 31, 2023. Included in these covenants are (a) a maximum Debt to Total Assets of 65% (approximately 14% at March 31, 2023) and (b) a minimum ratio of Adjusted EBITDA to Interest Expense of 1.5x (approximately 25x for the twelve months ended March 31, 2023) as well as covenants limiting the amount we can encumber our properties with mortgage debt.

Euro Denominated Unsecured Notes

Our Euro denominated unsecured notes (the “Euro Notes”) consist of four tranches: (i) €242.0 million issued to institutional investors on November 3, 2015, (ii) €100.0 million issued to institutional investors on April 12, 2016, (iii) €500.0 million issued in a public offering on January 24, 2020, and (iv) €700.0 million issued in a public offering on September 9, 2021. The Euro Notes have financial covenants similar to those of the U.S. Dollar Denominated Unsecured Notes.

We reflect changes in the U.S. Dollar equivalent of the amount payable including the associated interest, as a result of changes in foreign exchange rates as “Foreign currency exchange (loss) gain” on our income statement (losses of $27.1 million and gains of $35.4 million for the three months ended March 31, 2023 and 2022, respectively).

Mortgage Notes

We assumed our non-recourse mortgage debt in connection with property acquisitions, and we recorded such debt at fair value with any premium or discount to the stated note balance amortized using the effective interest method.

The holders of our Preferred Shares have general preference rights with respect to liquidation, quarterly distributions, and any accumulated unpaid distributions. Except as noted below, holders of the Preferred Shares do not have voting rights. In the event of a cumulative arrearage equal to six quarterly dividends, holders of all outstanding series of preferred shares (voting as a single class without regard to series) will have the right to elect two additional members to serve on our Board of Trustees (our “Board”) until the arrearage has been cured. At March 31, 2023, there were no dividends in arrears. The affirmative vote of at least 66.67% of the outstanding shares of a series of Preferred Shares is required for any material and adverse amendment to the terms of such series. The affirmative vote of at least 66.67% of the outstanding shares of all of our Preferred Shares, voting as a single class, is required to issue shares ranking senior to our Preferred Shares.

Except under certain conditions relating to the Company’s qualification as a REIT, the Preferred Shares are not redeemable prior to the dates indicated on the table above. On or after the respective dates, each of the series of Preferred Shares is redeemable at our option, in whole or in part, at $25.00 per depositary share, plus accrued and unpaid dividends. Holders of the Preferred Shares cannot require us to redeem such shares.

Upon issuance of our Preferred Shares, we classify the liquidation value as preferred equity on our consolidated balance sheet with any issuance costs recorded as a reduction to Paid-in capital.

Dividends

On February 4, 2023, our Board of Trustees declared a 50% increase in its regular common quarterly dividend from $2.00 to $3.00 per share. The distribution equates to an annualized increase to the Company’s regular common dividend from $8.00 to $12.00 per share.

Preferred share dividends paid totaled $48.7 million and $48.4 million for the three months ended March 31, 2023 and 2022, respectively.

10.Related Party Transactions

At March 31, 2023, Tamara Hughes Gustavson, a current member of our Board, held less than a 0.1% equity interest in, and is a manager of, a limited liability company that owns 65 self-storage facilities in Canada. Two of Ms. Gustavson’s adult children owned the remaining equity interest in the limited liability company. These facilities operate under the Public Storage® tradename, which we license to the owners of these facilities for use in Canada on a royalty-free, non-exclusive basis. We have no ownership interest in these facilities and we do not own or operate any facilities in Canada. If we chose to acquire or develop our own facilities in Canada, we would have to share the use of the Public Storage® name in Canada. We have a right of first refusal, subject to limitations, to acquire the stock or assets of the corporation engaged in the operation of these facilities if their owners agree to sell them. Our subsidiaries reinsure risks relating to loss of goods stored by customers in these facilities, and have received premium payments of approximately $0.5 million for each of the three months ended March 31, 2023 and 2022.

11.Share-Based Compensation

Under various share-based compensation plans and under terms established or modified by our Board or a committee thereof, we grant equity awards to trustees, officers, and key employees, including non-qualified options to purchase the Company’s common shares, restricted share units (“RSUs”), deferred share units (“DSUs”), and unrestricted common shares issued in lieu of trustee compensation.

We recorded share-based compensation expense associated with our equity awards in the various expense categories in the Consolidated Statements of Income as set forth in the following table. In addition, $0.7 million and $1.0 million of share-based compensation cost was capitalized as real estate facilities for the three months ended March 31, 2023 and 2022, respectively.

	Three Months Ended March 31,
	2023		2022
	(Amounts in thousands)
Self-storage cost of operations	$	4,210	$	4,864
Ancillary cost of operations	31		266
General and administrative	5,604		8,798
Total	$	9,845	$	13,928

Included in share-based compensation is $0.5 million and $4.2 million during the three months ended March 31, 2023 and 2022, respectively, in connection with retirement acceleration as discussed in Note 2 to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022.

As of March 31, 2023, there was $100.4 million of total unrecognized compensation cost related to share-based compensation arrangements. This cost is expected to be recognized over a weighted-average period of three years.

Stock Options

We have service-based and performance-based stock options outstanding. Performance-based stock options outstanding vest upon meeting certain performance conditions or market conditions. Stock options generally vest over 3 to 5 years, expire 10 years after the grant date, and have an exercise price equal to the closing trading price of our

common shares on the grant date. New shares are issued for options exercised. Employees cannot require the Company to settle their awards in cash.

During the three months ended March 31, 2023, 117,168 stock options were granted, 150,658 options were exercised, and 25,816 options were forfeited. A total of 3,105,177 stock options were outstanding at March 31, 2023 (3,164,483 at December 31, 2022).

For the stock options granted during the three months ended March 31, 2023, vesting is dependent upon meeting certain market conditions over the three-year period from March 15, 2023 through March 14, 2026, with continued service-based vesting through the first quarter of 2028. These stock options require relative achievement of the Company’s total shareholder return as compared to the weighted average total shareholder return of specified peer groups and can result in grantees earning up to 200% of the target options originally granted.

For the three months ended March 31, 2023 and 2022, we incurred share-based compensation cost for outstanding stock options of $3.2 million and $3.9 million, respectively.

Restricted Share Units

We have service-based and performance-based RSUs outstanding, which generally vest over 5 to 8 years from the grant date. Performance-based RSUs outstanding vest upon meeting certain performance conditions or market conditions. Upon vesting, the grantee receives new common shares equal to the number of vested RSUs, less common shares withheld to satisfy the grantee’s statutory tax liabilities arising from the vesting.

During the three months ended March 31, 2023, 38,895 RSUs were granted, 12,514 RSUs were forfeited and 67,748 RSUs vested. The vesting resulted in the issuance of 48,817 common shares. A total of 434,680 RSUs were outstanding at March 31, 2023 (476,047 at December 31, 2022).

During the three months ended March 31, 2023, 37,211 RSUs were awarded where vesting is dependent upon meeting certain market conditions over a three-year period from March 15, 2023 through March 14, 2026, with continued service-based vesting through the first quarter of 2028. These RSUs require relative achievement of the Company’s total shareholder return as compared to the weighted average total shareholder return of specified peer groups and can result in grantees earning up to 200% of the target RSUs originally granted.

Also included in the RSUs granted during the three months ended March 31, 2023 are 1,684 service-based RSUs.

For the three months ended March 31, 2023 and 2022, we incurred share-based compensation cost for RSUs of $7.2 million and $10.8 million, respectively.

Trustee Deferral Program

Non-management trustees may elect to receive all or a portion of their cash retainers in cash, unrestricted common shares, or fully-vested DSUs to be settled at a specified future date. Unrestricted common shares and/or DSUs will be granted to the non-management trustee on the last day of each calendar quarter based on the cash retainer earned for that quarter and converted into a number of shares or units based on the applicable closing price of our common shares on such date. During the three months ended March 31, 2023, we granted 501 DSUs and 212 unrestricted common shares. During the three months ended March 31, 2023, 867 previously granted DSUs were settled in common shares.

12. Net Income per Common Share

We allocate net income to (i) noncontrolling interests based upon their contractual rights in the respective subsidiaries or for participating noncontrolling interests based upon their participation in both distributed and undistributed earnings of the Company, (ii) preferred shareholders, for distributions paid or payable, (iii) preferred shareholders, to the extent redemption cost exceeds the related original net issuance proceeds (a “preferred share redemption charge”), and (iv) RSUs, for non-forfeitable dividends paid and adjusted for participation rights in undistributed earnings of the Company.

We calculate basic and diluted net income per common share based upon net income allocable to common shareholders, divided by (i) weighted average common shares for basic net income per common share, and (ii) weighted average common shares adjusted for the impact of dilutive stock options outstanding for diluted net income per common share. Potentially dilutive stock options representing 264,512 common shares were excluded from the computation of diluted earnings per share for the three months ended March 31, 2023, because their effect would have been antidilutive.

The following table reconciles the numerators and denominators of the basic and diluted net income per common shares computation for the three months ended March 31, 2023 and 2022, respectively (in thousands, except per share amounts):

	Three Months Ended March 31,

14. Commitments and Contingencies

Contingent Losses

We are a party to various legal proceedings and subject to various claims and complaints; however, we believe that the likelihood of these contingencies resulting in a material loss to the Company, either individually or in the aggregate, is remote.

Insurance and Loss Exposure

We carry property, earthquake, general liability, employee medical insurance, and workers compensation coverage through internationally recognized insurance carriers, subject to deductibles. Our deductible for general liability is $2.0 million per occurrence. Our annual deductible for property loss is $25.0 million per occurrence. This deductible decreases to $5.0 million once we reach $35.0 million in aggregate losses for occurrences that exceed $5.0 million. Insurance carriers’ aggregate limits on these policies of $75.0 million for property losses and $102.0 million for general liability losses are higher than estimates of maximum probable losses that could occur from individual catastrophic events determined in recent engineering and actuarial studies; however, in case of multiple catastrophic events, these limits could be exceeded.

We reinsure a program that provides insurance to our customers from an independent third-party insurer. This program covers customer claims for losses to goods stored at our facilities as a result of specific named perils (earthquakes are not covered by this program), up to a maximum limit of $5,000 per storage unit. We reinsure all risks in this program, but purchase insurance to cover this exposure for a limit of $15.0 million for losses in excess of $5.0 million per occurrence. We are subject to licensing requirements and regulations in all states. Customers participate in the program at their option. At March 31, 2023, there were approximately 1.3 million certificates held by our self-storage customers, representing aggregate coverage of approximately $5.8 billion.

Commitments

We have construction commitments representing future expected payments for construction under contract totaling $249.5 million at March 31, 2023. We expect to pay approximately $189.6 million in the remainder of 2023, $59.4 million in 2024, and $0.5 million in 2025 for these construction commitments.

We have future contractual payments on land, equipment and office space under various lease commitments totaling $62.5 million at March 31, 2023. We expect to pay approximately $2.1 million in the remainder of 2023, $3.1 million in 2024, $3.0 million in each of 2025 and 2026, $2.1 million in 2027, and $49.2 million thereafter for these commitments.

15.    Subsequent Events

Subsequent to March 31, 2023, we acquired or were under contract to acquire 12 self-storage facilities across three states with 0.9 million net rentable square feet, for $139.0 million.

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.

During the three months ended March 31, 2023, there were no material changes to our critical accounting estimates as compared to the critical accounting estimates disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2022.

Overview

Our self-storage operations generate most of our net income, and our earnings growth is impacted by the levels of 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). Accordingly, a significant portion of management’s time is devoted to maximizing cash flows from our existing self-storage facility portfolio.

During the three months ended March 31, 2023, revenues generated by our Same Store Facilities increased by 9.8% ($75.5 million), as compared to the same period in 2022, while Same Store cost of operations increased by 5.6% ($11.0 million). Demand and operating trends softened in the second half of 2022 continuing through the first quarter of 2023 and returned to historical seasonal patterns as compared to what we experienced in 2020 and 2021. We expect these trends to lead to moderating levels of income growth through 2023.

In addition to managing our existing facilities for organic growth, 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 2021, we acquired a total of 311 facilities with 27.0 million net rentable square feet for $5.9 billion. In our non-same store portfolio, we also have developed and expanded self-storage facilities of 15.6 million net rentable square feet for a total cost of $1.3 billion. During the three months ended March 31, 2023, net operating income generated by our Acquired Facilities and Newly Developed and Expanded Facilities increased 31.7% ($25.3 million), as compared to the same period in 2022.

We have experienced recent inflationary impacts on our cost of operations including labor, utilities, and repairs and maintenance, and costs of development and expansion activities, and we may continue to experience such impacts in the future. We have implemented various initiatives to manage the adverse impacts, such as enhancements in operational processes and investments in technology to reduce payroll hours, achievement of economies of scale from recent acquisitions with supervisory payroll allocated over a broader number of self-storage facilities, and investments in solar power and LED lights to lower utility usage.

In order to enhance the competitive position of certain of our facilities relative to local competitors (including newly developed facilities), we have embarked on our multi-year Property of Tomorrow program to (i) rebrand our properties with more pronounced, attractive, and clearly identifiable color schemes and signage, (ii) enhance the energy efficiency of our properties, and (iii) upgrade the configuration and layout of the offices and other customer zones to improve the customer experience. We expect to complete the program in 2025. We spent approximately $32 million on the program in the three months ended March 31, 2023 and expect to spend approximately $160 million over 2023 on this effort.

Results of Operations

Operating Results for the Three Months Ended March 31, 2023 and 2022

For the three months ended March 31, 2023, net income allocable to our common shareholders was $467.6 million or $2.65 per diluted common share, compared to $464.1 million or $2.63 per diluted common share for the same period in 2022, representing an increase of $3.5 million or $0.02 per diluted common share. The increase is due primarily to (i) a $92.0 million increase in self-storage net operating income and (ii) a $15.3 million increase in interest and other income, partially offset by (iii) a $62.2 million increase in foreign currency exchange losses primarily associated with our Euro denominated notes payable and (iv) a $37.4 million decrease in equity in earnings of unconsolidated real estate entities due to our sale of PSB in July 2022.

The $92.0 million increase in self-storage net operating income in the three months ended March 31, 2023 as compared to the same period in 2022 is a result of a $64.4 million increase attributable to our Same Store Facilities and a $27.6 million increase attributable to our non-same store facilities. Revenues for the Same Store Facilities increased 9.8% or $75.5 million in the three months ended March 31, 2023 as compared to the same period in 2022, due primarily to higher realized annual rent per occupied square foot, partially offset by a decline in occupancy. Cost of operations for the Same Store Facilities increased by 5.6% or $11.0 million in the three months ended March 31, 2023 as compared to the same period in 2022, due primarily to increased property tax expense, repairs and maintenance expenses, marketing expense, and other direct property costs. The increase in net operating income of $27.6 million for the non-same store facilities is due primarily to the impact of facilities acquired in 2021 and 2022 and the fill-up of recently developed and expanded facilities.

Funds from Operations and Core Funds from Operations

Funds from Operations (“FFO”) and 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 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 three months ended March 31, 2023, FFO was $3.94 per diluted common share as compared to $3.83 per diluted common share for the same period in 2022, representing an increase of 2.9%, or $0.11 per diluted common share.

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 contingency resolution, due diligence costs incurred in pursuit of strategic transactions, unrealized gain on private equity investments, and our equity share of severance of a senior executive from our equity investees. 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) the 2,348 facilities that we have owned and operated on a stabilized basis since January 1, 2021 (the “Same Store Facilities”), (ii) 311 facilities we acquired since January 1, 2021 (the “Acquired Facilities”), (iii) 136 facilities that have been newly developed or expanded, or that will commence expansion by December 31, 2023 (the “Newly Developed and Expanded Facilities”), and (iv) 82 other facilities, which are otherwise not stabilized with respect to occupancies or rental rates since January 1, 2021 (the “Other Non-same Store Facilities”). See Note 13 to our March 31, 2023 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 13 to our March 31, 2023 consolidated financial statements for a reconciliation of NOI to our total net income for all periods presented.

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, 2021. Our Same Store Facilities increased from 2,276 facilities at December 31, 2022 to 2,348 at March 31, 2023. The composition of our Same Store Facilities allows us more effectively to evaluate the ongoing performance of our self-storage portfolio in 2021, 2022, and 2023 and exclude the impact of fill-up of unstabilized facilities, which can significantly affect operating trends. We believe investors and analysts use Same Store 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 2,348 facilities (155.5 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 March 31, 2023. 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.

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 a year) 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 customers’ in-place rent and prevailing market rents, among other factors.

Revenues generated by our Same Store Facilities increased 9.8% in the three months ended March 31, 2023, as compared to the same period in 2022, due primarily to (i) a 12.4% increase in realized annual rent per occupied square foot, partially offset by (ii) a 2.4% decrease in average occupancy.

The increase in realized annual rent per occupied square foot in the three months ended March 31, 2023 as compared to the same period in 2022 was due to rate increases to existing long-term tenants, partially offset by a 7.5% decrease in average rates per square foot charged to new tenants moving in who replaced tenants moving out with higher rental rates during the three months ended March 31, 2023 as compared to the same period in 2022. The growth rate in realized annual rent per occupied square foot has decelerated since the second half of 2022 as a result of increases in moving-out activity that drove us to lower move-in rates and increase promotion discounts to replace tenants that vacate. At March 31, 2023, annual contract rent per occupied square foot was 10.8% higher as compared to March 31, 2022.

We experienced high occupancy levels throughout the three months ended March 31, 2023 with a weighted average square foot occupancy of 93.2%, representing a decrease of 2.4% as compared to the same period in 2022. Occupancy levels, although strong, have gradually declined since the second half of 2022 as move-out activity increased and customer demand softened. We lowered move-in rental rates and increased promotional activity and advertising spending to increase move-in activity at our facilities, which led to a year-over year 12.5% increase in move-in volumes that more than offset the year-over year 11.5% increase in move-out volumes for the three months ended March 31, 2023. Although the move-in volumes net of move-out volumes were higher in the three months ended March 31, 2023 as compared to the same period in 2022, at March 31, 2023, the average square foot occupancy was 92.8% as compared to 95.0% at March 31, 2022, due primarily to lower occupancy levels at December 31, 2022 of 92.3% as compared to December 31, 2021 of 94.7%.

Move-out volumes were partially impacted by rental rate increases to our existing tenants in the three months ended March 31, 2023 as compared to the same period in 2022. However, move-out activity from tenants not receiving increases was also higher in the three months ended March 31, 2023 as compared to the same period in 2022, returning to pre-2020 levels. Average length of stay of our tenants slightly increased in the three months ended March 31, 2023 as compared to the same period in 2022, which supported our revenue growth by contributing to the number of tenants eligible for rental rate increases.

Demand historically has been higher in the summer months than in the winter months and, as a result, rental rates charged to new tenants have typically been higher in the summer months than in the winter months. More typical seasonal patterns of demand with lower demand in the winter months returned in 2022. Demand fluctuates due to various local and regional factors, including the overall economy. Demand for our facilities is also impacted by new supply of self-storage space and alternatives to self-storage.

We expect weaker industry-wide demand in the remainder of 2023 as compared to 2022 driven by a weaker macroeconomic outlook and more limited moving activities, with move-out activities and occupancy levels returning to pre-2020 levels. To mitigate the negative impact of macroeconomic challenges, we will continue to support demand levels to our self-storage facilities with increased marketing expense, lowering rental rates to new customers, and increased promotional discounting. As a result, we expect revenue growth to decline significantly in the remainder of 2023 as compared to high levels of growth in 2022 and 2021. With a wide range of potential macroeconomic pathways for the remainder of 2023, the range of potential revenue growth rates is wide including the potential for year-over-year declines in revenue in the second half of 2023.

Late Charges and Administrative Fees

Late charges and administrative fees increased 14.5% in the three months ended March 31, 2023 as compared to the same period in 2022, due to (i) higher late charges collected on delinquent accounts driven by more delinquent accounts and to a lesser extent (ii) higher administrative fees resulting from higher move-in volumes.

Selected Key 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 three months ended March 31, 2023 and 2022. It 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.

	Three Months Ended March 31,
	2023		2022		Change

Analysis of Same Store Cost of Operations

Cost of operations (excluding depreciation and amortization) increased 5.6% in the three months ended March 31, 2023 as compared to the same period in 2022 due primarily to increased property tax expense, repairs and maintenance expense, marketing expense, and other direct property costs.

Property tax expense increased 5.0% in the three months ended March 31, 2023 as compared to the same period in 2022, as a result of higher assessed values. We expect property tax expense to grow 5.2% in 2023 due primarily to higher assessed values.

On-site property manager payroll expense increased 2.5% in the three months ended March 31, 2023 as compared to the same period in 2022, due primarily to increases in wage rates as a result of competitive labor conditions experienced in most geographical markets. We expect an inflationary increase in on-site property manager payroll expense in 2023 driven by increased wage rates, partially offset by expected reduction in labor hours driven by revisions in operational processes.

Repairs and maintenance expense increased 13.2% in the three months ended March 31, 2023 as compared to the same period in 2022. 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. We expect a moderate year-over-year increase in repairs and maintenance expense in the remainder of 2023.

Marketing expense includes Internet advertising and the operating costs of our 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. We increased marketing expense by 32.7% in the three months ended March 31, 2023 as compared to the same period in 2022, by utilizing a higher volume of online paid search programs to attract new tenants.

Other direct property costs include administrative expenses specific to each self-storage facility, such as property loss, telephone and data communication lines, business license costs, bank charges related to processing the facilities’ cash receipts, tenant mailings, credit card fees, eviction costs, and the cost of operating each property’s rental office. These costs increased 12.0% in the three months ended March 31, 2023 as compared to the same period in 2022. These increases were due primarily to an increase in credit card fees as a result of year-over-year increases in revenues, and to a lesser extent, a long-term trend of more customers paying with credit cards rather than cash, checks, or other methods of payment with lower transaction costs. We expect a moderate increase in other direct property costs in the remainder of 2023 primarily driven by an increase in credit card fees.

(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.

(c)The Acquired Facilities have an aggregate of approximately 27.0 million net rentable square feet, including 10.9 million in Texas, 3.9 million in Maryland, 1.6 million in Florida, 1.2 million in Virginia, 1.0 million in Oklahoma, 0.9 million in North Carolina, 0.7 million in Idaho, 0.6 million in each of Arizona, Colorado, and South Carolina, 0.5 million in Nebraska, 0.4 million in each of Georgia, Indiana, and Oregon, 0.3 million in each of California, Minnesota, Nevada, Ohio, Tennessee, and Washington, and 1.5 million in other states.

(d)We have completed the expansion projects on facilities acquired in 2021 for $26.7 million, adding 179,000 net rentable square feet of storage space as of March 31, 2023.

We have been active in acquiring facilities in recent years. Since the beginning of 2021, we acquired a total of 311 facilities with 27.0 million net rentable square feet for $5.9 billion. During the three months ended March 31, 2023, these facilities contributed net operating income of $62.3 million, consistent with our original underwritten expectations.

During 2021, we acquired the ezStorage portfolio, consisting of 48 properties (4.1 million net rentable square feet) for acquisition cost of $1.8 billion. As of March 31, 2023, we have completed the expansion projects on four properties of this portfolio for $26.3 million, adding 169,000 net rentable square feet of storage space. Included in the Acquisition results in the table above are ezStorage portfolio revenues of $25.6 million, NOI of $20.0 million (including Direct NOI of $20.5 million), and average square footage occupancy of 85.7% for the three months ended March 31, 2023.

During 2021, we acquired the All Storage portfolio, consisting of 56 properties (7.5 million net rentable square feet) for $1.5 billion. Included in the Acquisition results in the table above are All Storage portfolio revenues of $21.4 million, NOI of $13.3 million (including Direct NOI of $14.2 million), and average square footage occupancy of 78.5% for the three months ended March 31, 2023.

We remain active in seeking to acquire additional self-storage facilities. Subsequent to March 31, 2023, we acquired or were under contract to acquire 12 self-storage facilities across three states with 0.9 million net rentable square feet, for $139.0 million. Future acquisition volume is likely to be impacted by increasing cost of capital requirements and overall macro-economic uncertainties.

Developed and Expanded Facilities

The developed and expanded facilities include 49 facilities that were developed on new sites since January 1, 2018, and 87 facilities expanded to increase their net rentable square footage. Of these expansions, 61 were completed before 2022, 13 were completed in 2022 or 2023, and 13 are currently in process at March 31, 2023.

(a)Represents the percentage change with respect to square foot occupancy and annual contract rent per occupied square foot, and the absolute nominal change with respect to all other items.

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

(c)The facilities included above have an aggregate of approximately 15.6 million net rentable square feet at March 31, 2023, including 3.7 million in Texas, 3.0 million in Florida, 2.1 million in California, 1.4 million in each of Colorado and Minnesota, 0.8 million in North Carolina, 0.7 million in Michigan, 0.4 million in Missouri, 0.3 million in each of New Jersey, South Carolina, Virginia, and Washington, and 0.9 million in other states.

(d)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.

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, as well as the related construction and development overhead expenses included in general and administrative expense.

We typically underwrite new developments to stabilize at approximately an 8.0% NOI yield on cost. 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 March 31, 2023. We incurred a total of $625.6 million in direct cost to expand these facilities, demolished a total of 1.1 million net rentable square feet of storage space, and built a total of 6.1 million net rentable square feet of new storage space.

At March 31, 2023, we had 25 additional facilities in development, which will have a total of 2.4 million net rentable square feet of storage space and have an aggregate development cost totaling approximately $537.8 million. We expect these facilities to open over the next 18 to 24 months.

The facilities under “expansion in process” represent those facilities where construction is in process at March 31, 2023, and together with additional future expansion activities primarily related to our Same Store Facilities at March 31, 2023, we expect to add a total of 2.4 million net rentable square feet of storage space by expanding existing self-storage facilities for an aggregate direct development cost of $488.2 million.

38

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, 2021, including facilities 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 6.8 million net rentable square feet, including 1.2 million in Texas, 0.5 million in Pennsylvania, 0.4 million in each of California, Illinois, Michigan, Ohio, and Washington, 0.3 million in each of Arizona, Florida, and South Carolina, 0.2 million in each of Alabama, Colorado, Georgia, Minnesota, Missouri, and Virginia, and 1.0 million in other states.

During the three months ended March 31, 2023 and 2022, the average occupancy for these facilities totaled 86.2% and 89.1%, respectively, and the realized rent per occupied square foot totaled $17.83 and $15.24, respectively.

Depreciation and amortization expense

Depreciation and amortization expense for Self-Storage Operations decreased $0.5 million in the three months ended March 31, 2023, as compared to the same period in 2022, due to a decline in amortization of intangible assets related to our 2021 and 2022 acquisitions.

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:

	Three Months Ended March 31,
	2023		2022		Change
	(Amounts in thousands)
Revenues:
Tenant reinsurance premiums	$	49,298	$	45,195	$	4,103
Merchandise	6,820		6,871		(51)
Third party property management	5,930		4,364		1,566
Total revenues	62,048		56,430		5,618
Cost of operations:
Tenant reinsurance	9,572		7,277		2,295
Merchandise	4,213		3,904		309
Third party property management	5,891		4,334		1,557
Total cost of operations	19,676		15,515		4,161
Net operating income:
Tenant reinsurance	39,726		37,918		1,808
Merchandise	2,607		2,967		(360)
Third party property management	39		30		9
Total net operating income	$	42,372	$	40,915	$	1,457

Tenant reinsurance operations: Tenant reinsurance premium revenue increased $4.1 million or 9.1% in the three months ended March 31, 2023 over the same period in 2022, 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. Tenant reinsurance premium revenue generated from tenants at our Same-Store Facilities were $37.1 million and $35.8 million in the three months ended March 31, 2023 and 2022, respectively, representing a 3.6% increase.

We expect future growth will come primarily from customers of newly acquired and developed facilities, as well as additional tenants at our existing unstabilized self-storage facilities.

39

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 customer losses, such as burglary, as well as catastrophic weather events affecting multiple properties such as hurricanes and floods.

Merchandise sales: Sales of locks, boxes, and packing supplies at our self-storage facilities are primarily impacted by the level of move-ins and other customer traffic at our self-storage facilities. We do not expect any significant changes in revenues or profitability from our merchandise sales in the remainder of 2023.

Third-party property management: At March 31, 2023, in our third-party property management program, we managed 116 facilities for unrelated third parties, and were under contract to manage 77 additional facilities including 71 facilities that are currently under construction. During the three months ended March 31, 2023, we added seven facilities to the program and had six properties exit the program due to sales to other buyers. 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 entities

We account for the equity investments in PSB (prior to the sale of our investment in PSB) and Shurgard using the equity method and record our pro-rata share of the net income of these entities. The following table, and the discussion below, sets forth our equity in earnings of unconsolidated real estate entities:

	Three Months Ended March 31,
	2023		2022		Change
	(Amounts in thousands)
Equity in earnings:
PSB	$	—	$	36,886	$	(36,886)
Shurgard	5,995		6,538		(543)
Total equity in earnings	$	5,995	$	43,424	$	(37,429)

Investment in PSB: On July 20, 2022, in connection with the closing of the merger of PSB with Blackstone, we completed the sale of our 41% common equity interest in PSB in its entirety. At the close of the merger transaction, we received a total of $2.7 billion of cash proceeds and recognized a gain of $2.1 billion during the third quarter of 2022.

Since the sale of PSB in July 2022, we no longer recognize equity in earnings from PSB. Included in our equity earnings from PSB for the three months ended March 31, 2022 is our equity share of gains on sale of real estate totaling $23.6 million. Our equity share of earnings from PSB contributed $25.5 million to Core FFO in the three months ended March 31, 2022.

Investment in Shurgard: For purposes of recording our equity in earnings from Shurgard, the Euro was translated at exchange rates of approximately 1.088 U.S. Dollars per Euro at March 31, 2023 (1.070 at December 31, 2022), and average exchange rates of 1.073 and 1.122 for the three months ended March 31, 2023 and 2022, respectively. Included in our equity in earnings from Shurgard were $8.5 million and $8.3 million of our share of depreciation and amortization expense for the three months ended March 31, 2023 and 2022, respectively.

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

	Three Months Ended March 31,
	2023		2022		Change
	(Amounts in thousands)
Share-based compensation expense	$	5,604	$	8,798	$	(3,194)

Other costs	4,149		2,611		1,538
Total	$	25,544	$	23,069	$	2,475

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

	Three Months Ended March 31,
	2023		2022		Change
	(Amounts in thousands)
Interest earned on cash balances	$	11,859	$	136	$	11,723
Commercial operations	2,383		2,082		301
Unrealized gain on private equity investments	2,218		—		2,218
Other	2,174		1,161		1,013
Total	$	18,634	$	3,379	$	15,255

Interest expense: For the three months ended March 31, 2023 and 2022, we incurred $37.8 million and $34.3 million, respectively, of interest on our outstanding notes payable. In determining interest expense, these amounts were offset by capitalized interest of $1.7 million and $1.2 million during the three months ended March 31, 2023 and 2022, respectively, associated with our development activities. The increase of interest expense in the three months ended March 31, 2023 as compared to the same period in 2022 is due to the increase of Compounded Secured Overnight Financing Rate (“SOFR”) on our $700.0 million variable rate unsecured notes, partially offset by the interest savings on the $500.0 million unsecured notes redeemed in August 2022. At March 31, 2023, we had $6.9 billion of notes payable outstanding, with a weighted average interest rate of approximately 2.2%.

Foreign Currency Exchange (Loss) Gain: For the three months ended March 31, 2023 and 2022, we recorded foreign currency losses of $26.9 million and gains of $35.4 million, respectively, representing primarily the changes in the U.S. Dollar equivalent of our Euro-denominated unsecured notes due to fluctuations in exchange rates. The Euro was translated at exchange rates of approximately 1.088 U.S. Dollars per Euro at March 31, 2023, 1.070 at December 31, 2022, 1.111 at March 31, 2022, and 1.134 at December 31, 2021. 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.

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 increased from $200 million to $300 million per year in recent years to approximately $700 million in 2021 and $1 billion in 2022. 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 $400 million for 2023.

Capital needs in excess of retained cash flow are met with: (i) medium and long-term debt, (ii) preferred equity, and (iii) 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. We view our line of credit, as well as any short-term bank loans, as bridge financing.

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.

We have a $500.0 million revolving line of credit that we are able to use as temporary “bridge” financing until we are able to raise longer term capital. As of March 31, 2023 and May 3, 2023, 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 $480.6 million as of May 3, 2023. Our line of credit matures on April 19, 2024.

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. While the costs of financing have increased recently, 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 deteriorated 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) $695.4 million of cash as of March 31, 2023 and (ii) approximately $400.0 million of expected retained operating cash flow over the next twelve months. We believe that our 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) $139.0 million in property acquisitions currently under contract, (ii) $648.6 million of remaining spending on our current development pipeline, which will be incurred primarily in the next 18 to 24 months, and (iii) $8.2 million in scheduled principal repayments on our mortgage notes in the next twelve months. We have no principal payments on unsecured notes until April 2024. 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, issuing debt, or entering into joint venture arrangements to acquire or develop facilities.

42

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 March 31, 2023, the principal outstanding on our debt totaled approximately $6.9 billion, consisting of $10.0 million of secured notes payable, $1.7 billion of Euro-denominated unsecured notes payable and $5.3 billion of U.S. Dollar denominated unsecured notes payable. Approximate principal maturities and interest payments (including $44.5 million estimated interests on $700 million variable rate unsecured notes) are as follows (amounts in thousands):

	Principal		Interest		Total
Remainder of 2023	$	8,141	$	111,444	$	119,585
2024	808,903		128,998		937,901
2025	263,390		108,578		371,968
2026	1,150,138		101,402		1,251,540
2027	500,140		87,639		587,779
Thereafter	4,206,633		163,867		4,370,500
	$	6,937,345	$	701,928	$	7,639,273

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.

Capital expenditures totaled $93.7 million in the first three months of 2023 and are expected to approximate $450 million in 2023. In addition to standard capital repairs of building elements reaching the end of their useful lives, our capital expenditures in recent years have included incremental expenditures to enhance the competitive position of certain of our facilities relative to local competitors pursuant to a multi-year program. Such investments include development of more pronounced, attractive, and clearly identifiable color schemes and signage and upgrades to the configuration and layout of the offices and other customer zones to improve the customer experience. We spent approximately $32 million in the first three months of 2023 and expect to spend $160 million in 2023 on this effort. In addition, we have made investments in LED lighting and the installation of solar panels, which approximated $9 million for the three months ended March 31, 2023 and we expect to spend $132 million in 2023.

We believe that these incremental investments improve customer satisfaction, the attractiveness and competitiveness of our facilities to new and existing customers and, in the case of LED lighting and solar panels, reduce operating costs.

Requirement to Pay Distributions: For all periods presented herein, we have elected to be treated as a REIT, as defined in 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. We believe we have met these requirements in all periods presented herein, and we expect to continue to qualify as a REIT.

On May 2, 2023, our Board declared a regular common quarterly dividend of $3.00 per common share totaling approximately $526 million, which will be paid at the end of June 2023. This represented a 50% increase in the $2.00 per common share quarterly dividend paid during 2022. 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.

43

The annual distribution requirement with respect to our preferred shares outstanding at March 31, 2023 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 March 31, 2023, we acquired or were under contract to acquire 12 self-storage facilities for a total purchase price of $139.0 million.

We are actively seeking to acquire additional facilities. However, future acquisition volume will depend upon whether additional owners will be motivated to market their facilities, which will in turn depend upon factors such as economic conditions and the level of seller confidence.

As of March 31, 2023, we had development and expansion projects at a total cost of approximately $1.0 billion. Costs incurred through March 31, 2023 were $377.3 million, with the remaining cost to complete of $648.6 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.

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 May 3, 2023, we have two series of preferred securities that are eligible for redemption, at our option and with 30 days’ notice: our 5.150% Series F Preferred Shares ($280.0 million) and our 5.050% Series G Preferred Shares ($300.0 million). See Note 9 to our March 31, 2023 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 management to repurchase up to 35,000,000 of our common shares on the open market or in privately negotiated transactions. During three months ended March 31, 2023, we did not repurchase any of our common shares. From the inception of the repurchase program through May 3, 2023, we have repurchased a total of 23,721,916 common shares at an aggregate cost of approximately $679.1 million. Future levels of common share repurchases will be dependent upon our available capital, investment alternatives and the trading price of our common shares.

44

ITEM 3.    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 $6.9 billion at March 31, 2023, is the only market-risk sensitive portion of our capital structure.

The fair value of our debt at March 31, 2023 is approximately $6.0 billion. The table below summarizes the annual maturities of our debt, which had a weighted average effective rate of 2.2% at March 31, 2023. See Note 7 to our March 31, 2023 consolidated financial statements for further information regarding our debt (amounts in thousands).

	Remainder of 2023		2024		2025		2026		2027		Thereafter		Total
Debt	$	8,141	$	808,903	$	263,390	$	1,150,138	$	500,140	$	4,206,633	$	6,937,345

We have foreign currency exposure at March 31, 2023 related to (i) our investment in Shurgard, with a book value of $285.7 million, and a fair value of $1.5 billion based upon the closing price of Shurgard’s stock on March 31, 2023, and (ii) €1.5 billion ($1.7 billion) of Euro-denominated unsecured notes payable, providing a natural hedge against the fair value of our investment in Shurgard.

ITEM 4.    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 investments in certain unconsolidated real estate entities and because we do not control these entities, our disclosure controls and procedures with respect to such entities are substantially more limited than those we maintain with respect to our consolidated subsidiaries.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures, as required by Exchange Act Rule 13a-15(b), as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective, at a reasonable assurance level.

Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

45

Part II.        OTHER INFORMATION

ITEM 1.    Legal Proceedings

We are a party to various legal proceedings and subject to various claims and complaints; however, we believe that the likelihood of these contingencies resulting in a material loss to the Company, either individually or in the aggregate, is remote.

ITEM 1A.    Risk Factors

In addition to the other information in this Quarterly Report on Form 10-Q, you should carefully consider the risks described in our Annual Report on Form 10-K filed for the year ended December 31, 2022, in Part I, Item 1A, Risk Factors, and in our other filings with the SEC. These factors may materially affect our business, financial condition and operating results. There have been no material changes to the risk factors relating to the Company disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

In addition, in considering the forward-looking statements contained in this Quarterly Report on Form 10-Q and elsewhere, you should refer to the qualifications and limitations on our forward-looking statements that are described in Forward-Looking Statements at the beginning of Part I, Item 2 of this Quarterly Report on Form 10-Q.

ITEM 2.    Unregistered Sales of Equity Securities and Use of Proceeds

Common Share Repurchases

Our Board has authorized management to repurchase 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 May 3, 2023, we have repurchased a total of 23,721,916 common shares (all purchased prior to 2010) at an aggregate cost of approximately $679.1 million. Our common share repurchase program does not have an expiration date and there are 11,278,084 common shares that may yet be repurchased under our repurchase program as of March 31, 2023. We have no current plans to repurchase shares; however, future levels of common share repurchases will be dependent upon our available capital, investment alternatives, and the trading price of our common shares.

Description of the Business

Description of the Business

Public Storage (referred to herein as “the Company,” “we,” “us,” or “our”), a Maryland real estate investment trust that has elected to be taxed as a real estate investment trust (“REIT”), was organized in 1980. Our principal business activities include 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, ancillary activities such as tenant reinsurance, merchandise sales, and third party management, as well as the acquisition and development of additional self-storage space.

At March 31, 2023, we had direct and indirect equity interests in 2,877 self-storage facilities (with approximately 204.9 million net rentable square feet) located in 40 states in the United States (“U.S.”) operating under the Public Storage® name, and 1.2 million net rentable square feet of commercial and retail space.

At March 31, 2023, we owned a 35% common equity interest in Shurgard Self Storage Limited (“Shurgard”), a public company traded on the Euronext Brussels under the “SHUR” symbol, which owned 266 self-storage facilities (with approximately 15 million net rentable square feet) located in seven Western European countries, all operating under the Shurgard® name.

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

We have prepared the accompanying interim consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) as set forth in the Accounting Standards Codification of the Financial Accounting Standards Board (“FASB”), and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”). In our opinion, the interim consolidated financial statements presented herein reflect all adjustments, primarily of a normal recurring nature, that are necessary to present fairly the interim consolidated financial statements. Because they do not include all of the disclosures required by GAAP for complete annual financial statements, these interim consolidated financial statements should be read together with the audited Consolidated Financial Statements and related Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Certain amounts previously reported in our March 31, 2022 Statements of Cash Flows have been reclassified to conform to the March 31, 2023 presentation, with respect to the separate presentation of changes in operating assets and liabilities in the cash flows from operating activities section.

Disclosures of the number and square footage of facilities, as well as the number and coverage of tenant reinsurance policies (Note 14) are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.).

Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

Summary of Significant Accounting Policies

There have been no significant changes to the Company's significant accounting policies described in Note 2, Basis of Presentation and Summary of Significant Accounting Policies, in Notes to Consolidated Financial Statements included in Item 8 of Part II of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Investments in Unconsolidated Real Estate Entities

The following tables set forth our investments in, and equity in earnings of, the Unconsolidated Real Estate Entities (amounts in thousands):

PSB	$	—	$	36,886
Shurgard	5,995		6,538
Total	$	5,995	$	43,424

Investment in PSB

On July 20, 2022, in connection with the closing of the merger of PS Business Parks, Inc. (“PSB”) with affiliates of Blackstone Real Estate (“Blackstone”), we completed the sale of our 41% common equity interest in PSB in its entirety. At the close of the merger transaction, we received a total of $2.7 billion of cash proceeds and recognized a gain of $2.1 billion during the third quarter of 2022.

Since the sale of PSB in July 2022, we no longer recognize equity in earnings or receive cash distributions from PSB. During the three months ended March 31, 2022, we received cash distributions from PSB totaling $15.2 million.

Investment in Shurgard

Throughout all periods presented, we effectively owned, directly and indirectly 31,268,459 Shurgard common shares, representing a 35% equity interest in Shurgard.

Based upon the closing price at March 31, 2023 (€44.10 per share of Shurgard common stock, at 1.088 exchange rate of U.S. Dollars to the Euro), the shares we owned had a market value of approximately $1.5 billion.

Our equity in earnings of Shurgard comprised our equity share of Shurgard’s net income, less amortization of the Shurgard Basis Differential (defined below). During each of the three months ended March 31, 2023 and 2022, we received $0.9 million of trademark license fees that Shurgard pays to us for the use of the Shurgard® trademark. We eliminated $0.3 million of intra-entity profits and losses for each of the three months ended March 31, 2023 and 2022, representing our equity share of the trademark license fees. We classify the remaining license fees we receive from Shurgard as interest and other income on our income statement.

At March 31, 2023, our investment in Shurgard’s real estate assets exceeded our pro-rata share of the underlying amounts on Shurgard’s balance sheet by approximately $63.3 million ($67.8 million at December 31, 2022). This differential (the “Shurgard Basis Differential”) includes our basis adjustments in Shurgard’s real estate assets net of related deferred income taxes. The Shurgard Basis Differential is being amortized as a reduction to equity in earnings of the Unconsolidated Real Estate Entities. Such amortization totaled approximately $4.5 million and $1.3 million during the three months ended March 31, 2023 and 2022, respectively.

As of March 31, 2023 and 2022, we translated the book value of our investment in Shurgard from Euro to U.S. Dollars and recorded $3.9 million other comprehensive income and $6.8 million other comprehensive loss during the three month ended March 31, 2023 and 2022, respectively.

At March 31, 2023 and May 3, 2023, we had no outstanding borrowings under this Credit Facility. We had undrawn standby letters of credit, which reduce our borrowing capacity, totaling $18.6 million at March 31, 2023 ($18.6 million at December 31, 2022).

U.S. Dollar Denominated Unsecured Notes

The U.S. Dollar denominated unsecured notes (the “U.S. Dollar Denominated Unsecured Notes”) have various financial covenants with which we were in compliance at March 31, 2023. Included in these covenants are (a) a maximum Debt to Total Assets of 65% (approximately 14% at March 31, 2023) and (b) a minimum ratio of Adjusted EBITDA to Interest Expense of 1.5x (approximately 25x for the twelve months ended March 31, 2023) as well as covenants limiting the amount we can encumber our properties with mortgage debt.

Euro Denominated Unsecured Notes

Our Euro denominated unsecured notes (the “Euro Notes”) consist of four tranches: (i) €242.0 million issued to institutional investors on November 3, 2015, (ii) €100.0 million issued to institutional investors on April 12, 2016, (iii) €500.0 million issued in a public offering on January 24, 2020, and (iv) €700.0 million issued in a public offering on September 9, 2021. The Euro Notes have financial covenants similar to those of the U.S. Dollar Denominated Unsecured Notes.

We reflect changes in the U.S. Dollar equivalent of the amount payable including the associated interest, as a result of changes in foreign exchange rates as “Foreign currency exchange (loss) gain” on our income statement (losses of $27.1 million and gains of $35.4 million for the three months ended March 31, 2023 and 2022, respectively).

Mortgage Notes

We assumed our non-recourse mortgage debt in connection with property acquisitions, and we recorded such debt at fair value with any premium or discount to the stated note balance amortized using the effective interest method.

At March 31, 2023, the related contractual interest rates of our mortgage notes are fixed, ranging between 3.2% and 7.1%, and mature between November 1, 2023 and July 1, 2030.

At March 31, 2023, approximate principal maturities of our Notes Payable are as follows (amounts in thousands):

The holders of our Preferred Shares have general preference rights with respect to liquidation, quarterly distributions, and any accumulated unpaid distributions. Except as noted below, holders of the Preferred Shares do not have voting rights. In the event of a cumulative arrearage equal to six quarterly dividends, holders of all outstanding series of preferred shares (voting as a single class without regard to series) will have the right to elect two additional members to serve on our Board of Trustees (our “Board”) until the arrearage has been cured. At March 31, 2023, there were no dividends in arrears. The affirmative vote of at least 66.67% of the outstanding shares of a series of Preferred Shares is required for any material and adverse amendment to the terms of such series. The affirmative vote of at least 66.67% of the outstanding shares of all of our Preferred Shares, voting as a single class, is required to issue shares ranking senior to our Preferred Shares.

Except under certain conditions relating to the Company’s qualification as a REIT, the Preferred Shares are not redeemable prior to the dates indicated on the table above. On or after the respective dates, each of the series of Preferred Shares is redeemable at our option, in whole or in part, at $25.00 per depositary share, plus accrued and unpaid dividends. Holders of the Preferred Shares cannot require us to redeem such shares.

Upon issuance of our Preferred Shares, we classify the liquidation value as preferred equity on our consolidated balance sheet with any issuance costs recorded as a reduction to Paid-in capital.

Dividends

On February 4, 2023, our Board of Trustees declared a 50% increase in its regular common quarterly dividend from $2.00 to $3.00 per share. The distribution equates to an annualized increase to the Company’s regular common dividend from $8.00 to $12.00 per share.

Common share dividends paid, including amounts paid to our restricted share unitholders, totaled $527.6 million ($3.00 per share) and $351.2 million ($2.00 per share) for the three months ended March 31, 2023 and 2022, respectively. Preferred share dividends paid totaled $48.7 million and $48.4 million for the three months ended March 31, 2023 and 2022, respectively.

Two of Ms. Gustavson’s adult children owned the remaining equity interest in the limited liability company. These facilities operate under the Public Storage® tradename, which we license to the owners of these facilities for use in Canada on a royalty-free, non-exclusive basis. We have no ownership interest in these facilities and we do not own or operate any facilities in Canada. If we chose to acquire or develop our own facilities in Canada, we would have to share the use of the Public Storage® name in Canada. We have a right of first refusal, subject to limitations, to acquire the stock or assets of the corporation engaged in the operation of these facilities if their owners agree to sell them. Our subsidiaries reinsure risks relating to loss of goods stored by customers in these facilities, and have received premium payments of approximately $0.5 million for each of the three months ended March 31, 2023 and 2022.

In addition, $0.7 million and $1.0 million of share-based compensation cost was capitalized as real estate facilities for the three months ended March 31, 2023 and 2022, respectively.

	Three Months Ended March 31,
	2023		2022
	(Amounts in thousands)
Self-storage cost of operations	$	4,210	$	4,864
Ancillary cost of operations	31		266
General and administrative	5,604		8,798
Total	$	9,845	$	13,928

Included in share-based compensation is $0.5 million and $4.2 million during the three months ended March 31, 2023 and 2022, respectively, in connection with retirement acceleration as discussed in Note 2 to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022.

As of March 31, 2023, there was $100.4 million of total unrecognized compensation cost related to share-based compensation arrangements. This cost is expected to be recognized over a weighted-average period of three years.

Stock Options

We have service-based and performance-based stock options outstanding. Performance-based stock options outstanding vest upon meeting certain performance conditions or market conditions. Stock options generally vest over 3 to 5 years, expire 10 years after the grant date, and have an exercise price equal to the closing trading price of our

common shares on the grant date. New shares are issued for options exercised. Employees cannot require the Company to settle their awards in cash.

During the three months ended March 31, 2023, 117,168 stock options were granted, 150,658 options were exercised, and 25,816 options were forfeited. A total of 3,105,177 stock options were outstanding at March 31, 2023 (3,164,483 at December 31, 2022).

For the stock options granted during the three months ended March 31, 2023, vesting is dependent upon meeting certain market conditions over the three-year period from March 15, 2023 through March 14, 2026, with continued service-based vesting through the first quarter of 2028. These stock options require relative achievement of the Company’s total shareholder return as compared to the weighted average total shareholder return of specified peer groups and can result in grantees earning up to 200% of the target options originally granted.

For the three months ended March 31, 2023 and 2022, we incurred share-based compensation cost for outstanding stock options of $3.2 million and $3.9 million, respectively.

Restricted Share Units

We have service-based and performance-based RSUs outstanding, which generally vest over 5 to 8 years from the grant date. Performance-based RSUs outstanding vest upon meeting certain performance conditions or market conditions. Upon vesting, the grantee receives new common shares equal to the number of vested RSUs, less common shares withheld to satisfy the grantee’s statutory tax liabilities arising from the vesting.

During the three months ended March 31, 2023, 38,895 RSUs were granted, 12,514 RSUs were forfeited and 67,748 RSUs vested. The vesting resulted in the issuance of 48,817 common shares. A total of 434,680 RSUs were outstanding at March 31, 2023 (476,047 at December 31, 2022).

During the three months ended March 31, 2023, 37,211 RSUs were awarded where vesting is dependent upon meeting certain market conditions over a three-year period from March 15, 2023 through March 14, 2026, with continued service-based vesting through the first quarter of 2028. These RSUs require relative achievement of the Company’s total shareholder return as compared to the weighted average total shareholder return of specified peer groups and can result in grantees earning up to 200% of the target RSUs originally granted.

Also included in the RSUs granted during the three months ended March 31, 2023 are 1,684 service-based RSUs.

For the three months ended March 31, 2023 and 2022, we incurred share-based compensation cost for RSUs of $7.2 million and $10.8 million, respectively.

Trustee Deferral Program

Non-management trustees may elect to receive all or a portion of their cash retainers in cash, unrestricted common shares, or fully-vested DSUs to be settled at a specified future date. Unrestricted common shares and/or DSUs will be granted to the non-management trustee on the last day of each calendar quarter based on the cash retainer earned for that quarter and converted into a number of shares or units based on the applicable closing price of our common shares on such date. During the three months ended March 31, 2023, we granted 501 DSUs and 212 unrestricted common shares. During the three months ended March 31, 2023, 867 previously granted DSUs were settled in common shares.

Earnings Per Share [Abstract]

Net Income per Common Share

Net Income per Common Share

We allocate net income to (i) noncontrolling interests based upon their contractual rights in the respective subsidiaries or for participating noncontrolling interests based upon their participation in both distributed and undistributed earnings of the Company, (ii) preferred shareholders, for distributions paid or payable, (iii) preferred shareholders, to the extent redemption cost exceeds the related original net issuance proceeds (a “preferred share redemption charge”), and (iv) RSUs, for non-forfeitable dividends paid and adjusted for participation rights in undistributed earnings of the Company.

We calculate basic and diluted net income per common share based upon net income allocable to common shareholders, divided by (i) weighted average common shares for basic net income per common share, and (ii) weighted average common shares adjusted for the impact of dilutive stock options outstanding for diluted net income per common share. Potentially dilutive stock options representing 264,512 common shares were excluded from the computation of diluted earnings per share for the three months ended March 31, 2023, because their effect would have been antidilutive.

The following table reconciles the numerators and denominators of the basic and diluted net income per common shares computation for the three months ended March 31, 2023 and 2022, respectively (in thousands, except per share amounts):

Segment Information

Our operating segments reflect the significant components of our operations where discrete financial information is evaluated separately by our chief operating decision maker.

Self-Storage Operations

The Self-Storage Operations reportable segment reflects the aggregated rental operations from the self-storage facilities we own from (i) Same Store Facilities, (ii) Acquired Facilities, (iii) Developed and Expanded Facilities, and (iv) Other Non-Same Store Facilities. The presentation in the table below sets forth the Net Operating Income (“NOI”) of this reportable segment, as well as the related depreciation expense. For all periods presented, substantially all of our real estate facilities, goodwill and other intangible assets, other assets, and accrued and other liabilities are associated with the Self-Storage Operations reportable segment.

Ancillary Operations

The Ancillary Operations reflects the combined operations of our tenant reinsurance, merchandise sales, and third party property management operating segments.

Commitments and Contingencies

Commitments and Contingencies

Contingent Losses

We are a party to various legal proceedings and subject to various claims and complaints; however, we believe that the likelihood of these contingencies resulting in a material loss to the Company, either individually or in the aggregate, is remote.

Insurance and Loss Exposure

We carry property, earthquake, general liability, employee medical insurance, and workers compensation coverage through internationally recognized insurance carriers, subject to deductibles. Our deductible for general liability is $2.0 million per occurrence. Our annual deductible for property loss is $25.0 million per occurrence. This deductible decreases to $5.0 million once we reach $35.0 million in aggregate losses for occurrences that exceed $5.0 million. Insurance carriers’ aggregate limits on these policies of $75.0 million for property losses and $102.0 million for general liability losses are higher than estimates of maximum probable losses that could occur from individual catastrophic events determined in recent engineering and actuarial studies; however, in case of multiple catastrophic events, these limits could be exceeded.

We reinsure a program that provides insurance to our customers from an independent third-party insurer. This program covers customer claims for losses to goods stored at our facilities as a result of specific named perils (earthquakes are not covered by this program), up to a maximum limit of $5,000 per storage unit. We reinsure all risks in this program, but purchase insurance to cover this exposure for a limit of $15.0 million for losses in excess of $5.0 million per occurrence. We are subject to licensing requirements and regulations in all states. Customers participate in the program at their option. At March 31, 2023, there were approximately 1.3 million certificates held by our self-storage customers, representing aggregate coverage of approximately $5.8 billion.

Commitments

We have construction commitments representing future expected payments for construction under contract totaling $249.5 million at March 31, 2023. We expect to pay approximately $189.6 million in the remainder of 2023, $59.4 million in 2024, and $0.5 million in 2025 for these construction commitments.

We have future contractual payments on land, equipment and office space under various lease commitments totaling $62.5 million at March 31, 2023. We expect to pay approximately $2.1 million in the remainder of 2023, $3.1 million in 2024, $3.0 million in each of 2025 and 2026, $2.1 million in 2027, and $49.2 million thereafter for these commitments.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

We have prepared the accompanying interim consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) as set forth in the Accounting Standards Codification of the Financial Accounting Standards Board (“FASB”), and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”). In our opinion, the interim consolidated financial statements presented herein reflect all adjustments, primarily of a normal recurring nature, that are necessary to present fairly the interim consolidated financial statements. Because they do not include all of the disclosures required by GAAP for complete annual financial statements, these interim consolidated financial statements should be read together with the audited Consolidated Financial Statements and related Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Certain amounts previously reported in our March 31, 2022 Statements of Cash Flows have been reclassified to conform to the March 31, 2023 presentation, with respect to the separate presentation of changes in operating assets and liabilities in the cash flows from operating activities section.

Disclosures of the number and square footage of facilities, as well as the number and coverage of tenant reinsurance policies (Note 14) are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.).

Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.
