1. ORGANIZATION AND NATURE OF OPERATIONS

National Storage Affiliates Trust was organized in the state of Maryland on May 16, 2013 and is a fully integrated, self-administered and self-managed real estate investment trust focused on the self storage sector. As used herein, "NSA," the "Company," "we," "our," and "us" refers to National Storage Affiliates Trust and its consolidated subsidiaries, except where the context indicates otherwise. The Company has elected and believes that it has qualified to be taxed as a real estate investment trust for U.S. federal income tax purposes ("REIT") commencing with its taxable year ended December 31, 2015.

Through its controlling interest as the sole general partner of NSA OP, LP (its "operating partnership"), a Delaware limited partnership formed on February 13, 2013, the Company is focused on the ownership, operation, and acquisition of self storage properties predominantly located within the top 100 metropolitan statistical areas throughout the United States. Pursuant to the operating partnership's Fourth Amended and Restated Agreement of Limited Partnership (the "LP Agreement"), the operating partnership is authorized to issue preferred units, Class A Units ("OP units") and Long-Term Incentive Plan Units ("LTIP units"). The Company also owns certain of its self storage properties through other consolidated subsidiaries of its operating partnership, which the Company refers to as "DownREIT partnerships." The DownREIT partnerships issue equity ownership interests that are intended to be economically equivalent to the Company's OP units ("DownREIT OP units").

The Company owned 807 consolidated self storage properties in 33 states and Puerto Rico with approximately 51.6 million rentable square feet in approximately 406,000 storage units as of June 30, 2025, excluding two properties classified as held for sale, that were sold to a third party in July 2025. These properties are managed with local operational focus and expertise.

As of June 30, 2025, the Company also managed through its property management platform an additional portfolio of 260 properties owned by the Company's unconsolidated real estate ventures. These properties contain approximately 18.1 million rentable square feet, configured in approximately 144,000 storage units and located across 24 states. The Company owns a 25% equity interest in each of its unconsolidated real estate ventures.

As of June 30, 2025, the Company operated and held ownership interests in 1,067 self storage properties located across 37 states and Puerto Rico with approximately 69.7 million rentable square feet in approximately 550,000 storage units, excluding properties classified as held for sale.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying condensed consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles ("GAAP") and have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") regarding interim financial reporting. Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the condensed consolidated financial statements have been included. The Company's results of operations for the quarterly and year to date periods are not necessarily indicative of the results to be expected for the full year or any other future period.

Principles of Consolidation

The Company's financial statements include the accounts of its operating partnership and its controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation of entities.

When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity ("VIE"), and if the Company is deemed to be the primary beneficiary, in accordance with authoritative guidance issued on the consolidation of VIEs. When an entity is not deemed to be a VIE, the Company considers the provisions of additional guidance to determine whether the general partner controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates all entities that are VIEs and of which the Company is deemed to be the primary beneficiary. The Company has determined that its operating partnership is a VIE. The sole significant asset of the Company is its investment in its operating partnership, and consequently, substantially all of the Company’s assets and liabilities represent those assets and liabilities of its operating partnership.

As of June 30, 2025, the Company's operating partnership was the primary beneficiary of, and therefore consolidated, 22 partnerships that are considered VIEs, which owned 49 self storage properties. The net book value of the real estate owned by these VIEs was $401.2 million and $407.1 million as of June 30, 2025 and December 31, 2024, respectively. For certain DownREIT partnerships which are subject to fixed rate mortgages payable, the carrying value of such fixed rate mortgages payable held by these VIEs was $172.9 million and $172.9 million as of June 30, 2025 and December 31, 2024, respectively. The creditors of the consolidated VIEs do not have recourse to the Company's general credit.

Long Lived Assets Held for Sale

The Company considers long-lived assets to be "held for sale" upon satisfaction of the following criteria: (a) management commits to a plan to sell an asset (or group of assets), (b) the asset is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets, (c) an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated, (d) the sale of the asset is probable and transfer of the asset is expected to be completed within one year, (e) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value and (f) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

Typically these criteria are all met when the relevant asset is under contract, significant non-refundable deposits have been made by the potential buyer, the assets are immediately available for transfer, and there are no contingencies related to the sale that may prevent the transaction from closing. However, each potential transaction is evaluated based on its separate facts and circumstances. Assets classified as held for sale are reported at the lesser of carrying value or fair value less estimated costs to sell and are not depreciated. As of June 30, 2025, the Company had $6.0 million of self storage properties classified as held for sale, consisting of two self storage properties that were sold to a third party in July 2025. There were no self storage properties held for sale as of December 31, 2024.

Revenue Recognition

Rental revenue

Rental revenue consists of space rentals and related fees. Management has determined that all of the Company's leases are operating leases. Substantially all leases may be terminated on a month-to-month basis and rental income is recognized ratably over the lease term using the straight-line method. Rents received in advance are deferred and recognized on a straight-line basis over the related lease term associated with the prepayment. Promotional discounts and other incentives are recognized as a reduction to rental income over the applicable lease term.

Other property-related revenue

Other property-related revenue primarily consists of ancillary revenues such as tenant insurance and/or tenant warranty protection-related access fees, sales of storage supplies and truck rentals which are recognized in the period earned.

The Company has tenant insurance and/or tenant warranty protection plan-related arrangements with insurance companies and the Company’s tenants. During the three months ended June 30, 2025 and 2024, the Company recognized $5.9 million and $5.3 million, respectively, of tenant insurance and tenant warranty protection plan revenues and during six months ended June 30, 2025 and 2024, the Company recognized $11.8 million and $10.9 million, respectively, of tenant insurance and tenant warranty protection plan revenues.

The Company sells boxes, packing supplies, locks, other retail merchandise and rents moving trucks at its properties. During the three months ended June 30, 2025 and 2024, the Company recognized retail sales of $0.4 million and $0.6 million, respectively and during the six months ended June 30, 2025 and 2024, the Company recognized retail sales of $0.8 million and $1.1 million, respectively.

Management fees and other revenue

Management fees and other revenue consist of property management fees, platform fees, call center fees, acquisition fees, amounts related to the facilitation of tenant warranty protection or tenant insurance programs for certain stores in the Company's consolidated portfolio and unconsolidated real estate ventures, access fees associated with tenant insurance-related arrangements, and profit distributions from the Company's interest in a reinsurance company.

With respect to the 2016 Joint Venture, the 2018 Joint Venture, the 2023 Joint Venture and the 2024 Joint Venture (each as defined in Note 5), the Company provides supervisory and administrative property management services, centralized call center services, and technology platform and revenue management services to the properties in the unconsolidated real estate ventures. The property management fees for the 2016 Joint Venture, the 2018 Joint Venture and the 2023 Joint Venture are equal to 6% of monthly gross revenues and net sales revenues from the assets of the unconsolidated real estate ventures, and the platform fees are equal to $1,250 per month per unconsolidated real estate venture property. The property management fees for the 2024 Joint Venture are equal to 4% of monthly gross revenues and net sales revenues from the assets of the unconsolidated real estate venture. With respect to the 2016 Joint Venture, the 2023 Joint Venture and the 2024 Joint Venture, the call center fee is equal to 1% of each of monthly gross revenues and net sales revenues. During the three months ended June 30, 2025 and 2024, the Company recognized property management fees, call center fees and platform fees of $4.7 million and $4.5 million, respectively, and during the six months ended June 30, 2025 and 2024, the Company recognized property management fees, call center fees and platform fees of $9.4 million and $8.7 million, respectively.

The Company also earns acquisition fees for properties acquired by the 2016 Joint Venture, the 2018 Joint Venture, the 2023 Joint Venture and the 2024 Joint Venture. These fees are based on a percentage of the gross capitalization of the acquired assets determined by the members of the 2016 Joint Venture, the 2018 Joint Venture, the 2023 Joint Venture and the 2024 Joint Venture, and are generally earned when the unconsolidated real estate ventures obtain title and control of an acquired property. During the six months ended June 30, 2025 and 2024, the Company recognized acquisition fees of $0.1 million and $0, respectively.

The Company provides or makes available tenant insurance or tenant warranty protection programs for tenants at its properties. For certain of the properties in the Company’s consolidated portfolio and unconsolidated real estate ventures, the Company provides such tenant insurance through the Company’s wholly-owned captive insurance company and a separate reinsurance company in which the Company has a partial ownership interest. With respect to properties in the Company’s unconsolidated real estate ventures, the Company receives 50% of all proceeds from tenant insurance and tenant warranty protection programs at each unconsolidated real estate venture property in exchange for facilitating the programs at those properties. During the three months ended June 30, 2025 and 2024, the Company recognized $7.1 million and $4.8 million, respectively, of revenue related to these activities and during the six months ended June 30, 2025 and 2024, the Company recognized $14.3 million and $9.5 million, respectively, of revenue related to these activities.

Gain on sale of self storage properties

The Company recognizes gains from disposition of properties only upon closing in accordance with the guidance on sales of nonfinancial assets. Profit on real estate sold is recognized upon closing when all, or substantially all, of the promised consideration has been received and is nonrefundable and the Company has transferred control of the facilities to the purchaser.

Investments in Unconsolidated Real Estate Ventures

The Company's investments in its unconsolidated real estate ventures are recorded under the equity method of accounting in the accompanying condensed consolidated financial statements. Under the equity method, the Company's investments in unconsolidated real estate ventures are stated at cost and adjusted for the Company's share of net earnings or losses and reduced by distributions. Equity in earnings (losses) is recognized based on the Company's ownership interest in the earnings (losses) of the unconsolidated real estate ventures, except for the 2024 Joint Venture, for which the Company follows the hypothetical liquidation at book value ("HLBV") method. The Company follows the "nature of the distribution approach" for classification of distributions from its unconsolidated real estate ventures in its condensed consolidated statements of cash flows. Under this approach, distributions are reported on the basis of the nature of the activity or activities that generated the distributions as either a return on investment, which are classified as operating cash flows, or a return of investment (e.g., proceeds from the unconsolidated real estate ventures' sale of assets) which are reported as investing cash flows.

Noncontrolling Interests

All of the limited partner equity interests ("OP equity") in its operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than its operating partnership. In the condensed consolidated statements of operations, the Company allocates net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to National Storage Affiliates Trust.

For transactions that result in changes to the Company's ownership interest in its operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interests is adjusted is reflected as an adjustment to additional paid-in capital on the condensed consolidated balance sheets.

Allocation of Net Income (Loss)

Effective July 1, 2024, in connection with the Company's internalization of its PRO structure, all outstanding subordinated performance units of our operating partnership ("subordinated performance units'") including all units of the DownREIT partnerships intended to be economically equivalent to the subordinated performance units ("DownREIT subordinated performance units") were converted into OP units and DownREIT OP units, respectively. For periods in which the subordinated performance units were outstanding, the Company allocated GAAP income utilizing the HLBV method, in which income or loss was allocated based on the change in each unitholders' claim on the net assets of its operating partnership at period end after adjusting for any distributions or contributions made during such period. For periods in which the subordinated performance units are not outstanding, the Company allocates GAAP income based on the number of common shares and partnership units (including DownREIT OP units) outstanding.

Other Comprehensive Income (Loss)

The Company has cash flow hedge derivative instruments that are measured at fair value with unrealized gains or losses recognized in other comprehensive income (loss) with a corresponding adjustment to accumulated other comprehensive income (loss) within equity, as discussed further in Note 12.

Cash and Cash Equivalents

The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. From time to time, the Company maintains cash balances in financial institutions in excess of federally insured limits. The Company has never experienced a loss that resulted from exceeding federally insured limits.

Restricted Cash

The Company's restricted cash consists of escrowed funds deposited with financial institutions resulting from property sales for which we elected to purchase replacement property in accordance with Section 1031 of the Code, and for real estate taxes, insurance and other reserves for capital improvements in accordance with the Company's loan agreements.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

3. SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS

Shareholders' Equity

Series A Preferred Shares

The Company's 6.000% cumulative redeemable preferred shares of beneficial interest ("Series A Preferred Shares") rank senior to the Company's common shares with respect to dividend rights and rights upon its liquidation, dissolution or winding up. Dividends on the Series A Preferred Shares, which are payable quarterly in arrears, are cumulative from the date of original issuance in the amount of $1.50 per share each year. The Series A Preferred Shares became redeemable by the Company in October 2022 for a cash redemption price of $25.00 per share, plus accrued but unpaid dividends. The increase in Series A Preferred Shares outstanding from December 31, 2024 to June 30, 2025, was due to the issuance of 2,387 Series A Preferred Shares upon the redemption of an equivalent number of 6.000% Series A-1 Cumulative Redeemable Preferred Units ("Series A-1 preferred units"). As of June 30, 2025 the Company had 9,029,717 Series A Preferred Shares issued and outstanding.

At the Market ("ATM") Program

On November 19, 2024, the Company and its operating partnership entered into a sales agreement with certain sales agents, forward sellers and forward purchasers, pursuant to which the Company may sell from time to time up to $400.0 million of the Company's common shares in sales deemed to be "at the market offerings" (the "sales agreement"). The sales agreement contemplates that, in addition to the issuance and sale by the Company of offered shares to or through the sale agents, the Company may enter into separate forward sale agreements with any forward purchaser. If the Company enters into a forward sale agreement with any forward purchaser, such forward purchaser will attempt to borrow from third parties and sell, through the related agent, acting as sales agent for such forward purchaser (each, a "forward seller"), offered shares, in an amount equal to the offered shares subject to such forward sale agreement, to hedge such forward purchaser’s exposure under such forward sale agreement. The Company may offer the common shares through the agents, as the Company's sales agents, or, as applicable, as forward seller, or directly to the agents or forward sellers, acting as principals, by means of, among others, ordinary brokers’ transactions on the NYSE or otherwise at market prices prevailing at the time of sale or at negotiated prices.

During the six months ended June 30, 2025, the Company did not sell any common shares through the ATM program. As of June 30, 2025, the Company had $400.0 million of capacity remaining under its most recent ATM Program.

Common Share Repurchase Program

On July 11, 2022, the Company approved a share repurchase program authorizing, but not obligating, the repurchase of up to $400.0 million of the Company's common shares from time to time. On December 1, 2023, the Company approved a new share repurchase program authorizing, but not obligating, the repurchase of up to $275.0 million of the Company's common shares from time to time. On November 14, 2024, the Company approved a new share repurchase program authorizing, but not obligating, the repurchase of up to $350.0 million of the Company's common shares from time to time. The timing, manner, price and amount of any repurchase transactions will be determined by the Company in its discretion and will be subject to share price, availability, trading volume and general market conditions. Under these programs, the Company did not repurchase any common shares during the six months ended June 30, 2025 and has remaining capacity of approximately $350.3 million.

Noncontrolling Interests

All of the OP equity in the Company's operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than the Company's operating partnership. NSA is the general partner of its operating partnership and is authorized to cause its operating partnership to issue additional partner interests, including preferred units, OP units and LTIP units at such prices and on such other terms as it determines in its sole discretion.

As of June 30, 2025 and December 31, 2024, units reflecting noncontrolling interests consisted of the following:


	June 30, 2025	December 31, 2024
Series A-1 preferred units	1,200,211	1,202,598
OP units	52,111,896	52,173,489
LTIP units	850,663	794,926
DownREIT units
DownREIT OP units	5,769,214	5,769,214
Total	59,931,984	59,940,227

Series A-1 Preferred Units

The Series A-1 preferred units rank senior to OP units and subordinated performance units in the Company's operating partnership with respect to distributions and liquidation. The Series A-1 preferred units have a stated value of $25.00 per unit and receive distributions at an annual rate of 6.000%. These distributions are cumulative. The Series A-1 preferred units are redeemable at the option of the holder after the first anniversary of the date of issuance, which redemption obligations may be satisfied at the Company’s option in cash in an amount equal to the market value of an equivalent number of the Series A Preferred Shares or the issuance of the Series A Preferred Shares on a one-for-one basis, subject to adjustments. Generally, the Series A-1 preferred units become redeemable by the Company beginning ten years after the initial issuance of each Series A-1 preferred unit at a stated value of $25.00 per unit, plus accrued but unpaid distributions. The decrease in Series A-1 preferred units outstanding from December 31, 2024 to June 30, 2025 was due to the redemption of 2,387 Series A-1 preferred units for an equivalent number of Series A Preferred Shares.

OP Units and DownREIT OP units

OP units in the Company's operating partnership are redeemable for cash or, at the Company's option, exchangeable for common shares on a one-for-one basis, and DownREIT OP units are redeemable for cash or, at the Company's option, exchangeable for OP units in its operating partnership on a one-for-one basis, subject to certain adjustments in each case. The holders of OP units are generally not entitled to elect redemption until one year after the issuance of the OP units. The holders of DownREIT OP units are generally not entitled to elect redemption until five years after the date of the contributor's initial contribution or such later date as may be agreed to by the contributor and the operating partnership.

The decrease in OP units outstanding from December 31, 2024 to June 30, 2025 was due to the redemption of 202,167 OP units for an equal number of common shares and the redemption of 3,664 OP units for cash, partially offset by the conversion of 144,238 LTIP units into an equivalent number of OP units.

LTIP Units

LTIP units are a special class of partnership interest in the Company's operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the OP units (subject to the achievement of specified levels of profitability by the Company's operating partnership or the achievement of certain events). LTIP units may also, under certain circumstances, be convertible into OP units on a one-for-one basis, which are then exchangeable for common shares as described above.

The increase in LTIP units outstanding from December 31, 2024 to June 30, 2025 was due to the issuance of 199,975 compensatory LTIP units to employees and trustees, net of forfeitures. This increase was partially offset by the conversion of 144,238 LTIP units into an equivalent number of OP units.

The 2023 JV Agreement provides for equity capital contributions by the 2023 JV Members of up to $400.0 million over a twenty-four month investment period (subject to two six-month extension options if both of the 2023 JV Members agree) starting in December 2023, with the 2023 JV Investor holding a 75% ownership interest and the 2023 NSA Member holding a 25% ownership interest.

A subsidiary of the Company is acting as the non-member manager of the 2023 Joint Venture (the "2023 NSA Manager"). The 2023 NSA Manager directs, manages and controls the day-to-day operations and affairs of the 2023 Joint Venture but may not cause the 2023 Joint Venture to make certain major decisions involving the business of the 2023 Joint Venture without the consent of both 2023 JV Members, including the approval of annual budgets, sales and acquisitions of properties, financings, and certain actions relating to bankruptcy.

Outstanding equity interests of the Company's operating partnership and DownREIT partnerships are considered potential common shares for purposes of calculating diluted earnings per share as the unitholders may, through the exercise of redemption rights, obtain common shares, subject to various restrictions. Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for unvested LTIP units subject to a service condition outstanding during the period and the if-converted method for any convertible securities outstanding during the period.

Generally, following certain lock-out periods, OP units in the Company's operating partnership are redeemable for cash or, at the Company's option, exchangeable for common shares on a one-for-one basis, subject to certain adjustments and DownREIT OP units are redeemable for cash or, at the Company's option, exchangeable for OP units in its operating partnership on a one-for-one basis, subject to certain adjustments in each case.

LTIP units may also, under certain circumstances, be convertible into OP units on a one-for-one basis, which are then exchangeable for common shares as described above. Certain LTIP units vested prior to or upon the completion of the Company's initial public offering and certain LTIP units have vested upon the satisfaction of a service or market condition or will vest upon the satisfaction of future service and market conditions. Vested LTIP units and unvested LTIP units that vest based on a service or market condition are allocated income or loss in a similar manner as OP units. Unvested LTIP units subject to a service or market condition are evaluated for dilution using the treasury stock method. For the three and six months ended June 30, 2025, 766,311 unvested LTIP units that vest based on a service or market condition are excluded from the calculation of diluted earnings per share as they are not dilutive to earnings per share.

Effective as of July 1, 2024, in connection with the Company's internalization of its PRO structure, all outstanding subordinated performance units and DownREIT subordinated performance units were converted into OP units and DownREIT OP units, respectively. For periods in which the subordinated performance units were outstanding, the Company calculated the potentially dilutive impact of such units by assuming a hypothetical conversion into OP units and DownREIT OP units and considering the GAAP income that was allocated to such units.

For the three months ended June 30, 2025 and 2024, potential common shares totaling 58.0 million and 58.0 million, respectively, related to OP units, DownREIT OP units and vested LTIP units have been excluded from the calculation of diluted earnings per share as they are not dilutive to earnings per share. For the six months ended June 30, 2025 and 2024, potential common shares totaling 58.0 million and 58.0 million, respectively, related to OP units, DownREIT OP units and vested LTIP units have been excluded from the calculation of diluted earnings per share as they are not dilutive to earnings per share.

Participating securities, which consist of unvested restricted common shares, receive dividends equal to those received by common shares. The effect of participating securities for the periods presented above is calculated using the two-class method of allocating distributed and undistributed earnings.

10. RELATED PARTY TRANSACTIONS

Effective July 1, 2024, in connection with the internalization of its PRO structure, the Company purchased the PROs' management contracts. As of June 30, 2025, the majority of operations have transitioned to the Company.

Supervisory and Administrative Fees

During the three months ended June 30, 2024, the Company incurred $5.1 million for supervisory and administrative fees to its former PROs pursuant to their respective management contracts and during the six months ended June 30, 2024, the Company incurred $10.2 million for supervisory and administrative fees to its former PROs pursuant to their respective management contracts. In connection with the internalization of the PRO structure, the Company entered into new asset management agreements with certain of its former PROs to continue to provide leasing, operating, supervisory and administrative services for certain self storage properties on a transitionary basis. These new asset management agreements generally provided for fees ranging from 5% to 6% of gross revenue for such managed self storage properties. Under the current asset management agreements with former PROs, during the three months ended June 30, 2025, the Company incurred $1.4 million for supervisory and administrative fees and during the six months ended June 30, 2025, the Company incurred $2.8 million for supervisory and administrative fees. Supervisory and administrative fees are included in general and administrative expenses in the accompanying condensed consolidated statements of operations.

Payroll Services

For the self storage properties that were managed by the Company's former PROs, and pursuant to their respective management contracts and new asset management agreements, the employees responsible for operations were employees of the Company's former PROs who charged the Company for the costs associated with the respective employees. For the three months ended June 30, 2025 and 2024, the Company incurred $1.8 million and $6.8 million, respectively, for payroll and related costs reimbursable to these former PROs and for the six months ended June 30, 2025 and 2024, the Company incurred $3.6 million and $13.7 million, respectively, for payroll and related costs reimbursable to these former PROs. Such costs are included in property operating expenses in the accompanying condensed consolidated statements of operations.

11. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company is subject to litigation, claims, and assessments that may arise in the ordinary course of its business activities. Such matters include contractual matters, employment related issues, and regulatory proceedings. Although occasional adverse decisions or settlements may occur, the Company believes that the final disposition of such matters will not have a material adverse effect on the Company's financial position, results of operations, or liquidity.

12. FAIR VALUE MEASUREMENTS

Recurring Fair Value Measurements

The Company sometimes limits its exposure to interest rate fluctuations by entering into interest rate swap agreements. The interest rate swap agreements moderate the Company's exposure to interest rate risk by effectively converting the interest on variable rate debt to a fixed rate. The Company does not use derivatives for trading or speculative purposes. The Company measures its interest rate swap derivatives at fair value on a recurring basis. The changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income (loss) and are subsequently reclassified into earnings in the period that the hedged transaction affects earnings.

Information regarding the Company's interest rate swaps measured at fair value, which are classified within Level 2 of the GAAP fair value hierarchy, is presented below (dollars in thousands):


				Fair Value
	Number of Contracts	Notional Amount		Other Assets, net		Interest Rate Swap Liabilities
As of June 30, 2025
Interest Rate Swaps	10	$	860,000	$	9,164	$	4,041

As of December 31, 2024
Interest Rate Swaps	12	$	1,085,000	$	22,596	$	471

The following table presents the effect of our derivative instruments on our condensed consolidated financial statements (dollars in thousands):


Fair value at December 31, 2023	$	26,160
(Gains) and losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive income (loss)	(18,718)
Unrealized gains and realized (losses) on interest rate swaps and forward starting swaps included in accumulated other comprehensive income (loss)	26,994
Fair value at June 30, 2024	$	34,436

Fair value at December 31, 2024	$	22,125
(Gains) and losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive income (loss)	(5,983)
Unrealized and realized losses on interest rate swaps and forward starting swaps included in accumulated other comprehensive income (loss)	(11,019)
Fair value at June 30, 2025	$	5,123

As of June 30, 2025 and December 31, 2024, the Company had outstanding interest rate swaps with aggregate current notional amounts of $860.0 million and $1,085.0 million, respectively, designated as cash flow hedges. As of June 30, 2025, the Company's swaps had a weighted average remaining term of approximately 2.8 years.

In connection with the issuance of fixed rate unsecured notes in the second quarter of 2023, we entered into $50.0 million of forward starting interest rate swaps on March 16, 2023, and a $25.0 million forward starting interest rate swap on March 24, 2023, locking the interest rate of compounded Secured Overnight Financing Rate ("SOFR") at 3.25% through April 5, 2023. These interest rate swaps have been designated as cash flow hedges. The realized loss of $1.6 million of the compounded SOFR swaps are included in unrealized and realized gains (loss) on derivative instruments in comprehensive income (loss) and will be reclassified into interest expense over 10 years, which is the term of anticipated unsecured fixed rate debt including any replacement debt thereof. Amounts reported in accumulated other comprehensive (loss) income will be reclassified into interest expense as interest payments are made on the anticipated debt.

The fair value of these swaps are included in other assets and liabilities in the Company's condensed consolidated balance sheets, and the Company recognizes any changes in the fair value as an adjustment of accumulated other comprehensive income (loss) within equity. If the forward rates at June 30, 2025 remain constant, the Company estimates that during the next 12 months, the Company would reclassify into earnings, as a reduction in interest expense, approximately $6.1 million of the unrealized gains included in accumulated other comprehensive income (loss). If market interest rates remain above the 3.08% weighted average fixed rate under these interest rate swaps, the Company will continue to receive payments due to it from its counterparties to the interest rate swaps.

There were no transfers between levels of the three-tier fair value measurement hierarchy during the six months ended June 30, 2025 and 2024. For financial assets and liabilities that utilize Level 2 inputs, the Company utilizes both direct and indirect observable price quotes, including applicable yield curves. The Company uses valuation techniques for Level 2 financial assets and liabilities which include applicable yield curves at the reporting date as well as assessing counterparty credit risk. Counterparties to these contracts are highly rated financial institutions. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with the Company's derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and the counterparties. As of June 30, 2025 and 2024, the Company determined that the effect of credit valuation adjustments on the overall valuation of its derivative positions are not significant to the overall valuation of its derivatives. Therefore, the Company has determined that its derivative valuations are appropriately classified in Level 2 of the fair value hierarchy.

Fair Value Disclosures

The carrying values of cash and cash equivalents, restricted cash, trade receivables, accounts payable and accrued liabilities reflected in the condensed consolidated balance sheets at June 30, 2025 and 2024, approximate fair value due to the short term nature of these financial assets and liabilities. The carrying value of variable rate debt financing, comprising the Revolver, term loans under our credit facility and our term loan facilities, reflected in the condensed consolidated balance sheets at June 30, 2025 and 2024, approximates fair value as the changes in their associated interest rates reflect the current market and credit risk, which is similar to when the loans were originally obtained.

The fair values of fixed rate private placement notes and mortgages were estimated using the discounted estimated future cash payments to be made on such debt; the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality (categorized within Level 2 of the fair value hierarchy).

The following table presents the carrying value and estimated fair value of our fixed rate private placement notes and mortgages (dollars in thousands):


	Carrying Value(1)				Fair Value
	June 30, 2025		December 31, 2024		June 30, 2025		December 31, 2024
Liabilities
Private Placement Notes	$	1,950,000	$	1,950,000	$	1,837,773	$	1,774,291
Mortgage Notes	199,718		200,793		194,239		190,966

(1) Carrying value represents the principal balance outstanding

13. Segments

The Company manages the business as one reportable segment consisting of owning and managing self storage properties located in the United States. The Company collects rental revenue from customers for space rentals and related fees. Although the Company has several operating segments consisting of self storage properties in different geographic markets, these operating segments have been aggregated into one reportable segment based on the similar economic characteristics among all markets. The Company considers factors such as the physical and economic characteristics of its properties and the related operating activities in determining its operating segments. Operating segments that exhibit similar physical and economic characteristics and other operating similarities have been aggregated. The Company has other operating segments, consisting of activities other than owning and managing self storage properties, that are insignificant based on the guidance set forth in ASC 280, and included under the heading "All Other."

The Company's chief operating decision maker ("CODM") is its President and Chief Executive Officer. The CODM uses net operating income ("NOI") to assess segment performance and allocate resources. NOI is the key measure used by the CODM to evaluate the economic productivity from owning and managing the Company's self storage properties, as it enables the CODM to evaluate the operating performance of the Company's self storage properties on a consistent and comparable basis from period to period.

Reportable segment asset information is not provided to the CODM as the CODM does not use segment asset information to evaluate the business and allocate resources.

The following table presents our reportable segment NOI for the three and six months ended June 30, 2025 and 2024 (dollars in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,

Net operating income	$	120,985	$	128,725	$	242,100	$	261,105

NOI represents rental revenue plus other property-related revenue, minus property operating expenses. NOI excludes management fees and other revenue, general and administrative expenses, depreciation and amortization, interest expense, loss on early extinguishment of debt, equity in losses (earnings) of unconsolidated real estate ventures, acquisition costs, non-operating (income) expense, gain on sale of self storage properties or income tax expense.

Overview

National Storage Affiliates Trust is a fully integrated, self-administered and self-managed real estate investment trust organized in the state of Maryland on May 16, 2013. We have elected and we believe that we have qualified to be taxed as a REIT commencing with our taxable year ended December 31, 2015. We serve as the sole general partner of our operating partnership, a Delaware limited partnership formed on February 13, 2013 to conduct our business, which is focused on the ownership, operation, and acquisition of self storage properties located predominantly within the top 100 metropolitan statistical areas throughout the United States.

Our vice chairperson of the board of trustees and former chairperson of the board of trustees and chief executive officer, Arlen D. Nordhagen, co-founded SecurCare Self Storage, Inc. in 1988 to invest in and manage self storage properties. While growing SecurCare to over 150 self storage properties, Mr. Nordhagen recognized a market opportunity for a differentiated public self storage REIT that would leverage the benefits of national scale by integrating multiple experienced regional self storage operators with local operational focus and expertise. Although the PRO structure contributed significantly to our growth over the last decade, the internalization of the PRO structure was always a part of our long term vision. Our former structure offered the former PROs a unique opportunity to serve as regional property managers for their managed portfolios and directly participate in the potential upside of those properties while simultaneously diversifying their investment to include a broader portfolio of self storage properties. Over time, largely through our unconsolidated real estate ventures, PRO retirements and the internalization of our PRO structure, effective July 1, 2024, we have developed a full service internally-staffed property management platform.

Our Structure

Through our property management platform, we direct, manage and control the day-to-day operations and affairs of our consolidated properties and our unconsolidated real estate ventures. As of June 30, 2025, our property management platform managed and controlled the majority of our 807 consolidated properties and all 260 of our unconsolidated real estate venture properties. The properties are primarily managed by us under the brands of iStorage, Move It, Moove In, Northwest, RightSpace, SecurCare and Southern.

We earn certain customary fees for managing and operating the properties in the unconsolidated real estate ventures and we facilitate tenant insurance and/or tenant warranty protection programs for tenants at these properties in exchange for half of all proceeds from such programs.

Our Consolidated Properties

We seek to own properties that are well located in high quality sub-markets with highly accessible street access and attractive supply and demand characteristics, providing our properties with strong and stable cash flows that we believe are less sensitive to the fluctuations of the general economy. Many of these markets have multiple barriers to entry against increased supply, including zoning restrictions against new construction and new construction costs that we believe are higher than our properties' fair market value.

As of June 30, 2025, we owned a geographically diversified portfolio of 807 self storage properties located in 33 states and Puerto Rico, comprising approximately 51.6 million rentable square feet, configured in approximately 406,000 storage units.

Our Unconsolidated Real Estate Ventures

We seek to opportunistically partner with institutional funds and other institutional investors to acquire attractive portfolios utilizing a promoted return structure. We believe there is significant opportunity for continued external growth by partnering with institutional investors seeking to deploy capital in the self storage industry. In addition, we consider the 75% third-party interest in the Company's unconsolidated real estate ventures, which currently own 260 properties, to present a potential acquisition opportunity. This 75% third-party share of gross real estate assets is approximately $2.0 billion based on the historical book value of the joint ventures. Were we to pursue an acquisition of these interests, it could potentially drive our future growth.

2024 Joint Venture

As of June 30, 2025, the 2024 Joint Venture, in which we have a 25% ownership interest, owned and operated 56 self storage properties containing approximately 3.2 million rentable square feet, configured in approximately 24,000 storage units and located across seven states.

2023 Joint Venture

As of June 30, 2025, the 2023 Joint Venture, in which we have a 25% ownership interest, owned and operated 19 self storage properties containing approximately 1.3 million rentable square feet, configured in approximately 8,000 storage units and located across three states.

2018 Joint Venture

As of June 30, 2025, the 2018 Joint Venture, in which we have a 25% ownership interest, owned and operated 104 self storage properties containing approximately 7.9 million rentable square feet, configured in approximately 65,000 storage units and located across 17 states.

2016 Joint Venture

As of June 30, 2025, the 2016 Joint Venture, in which we have a 25% ownership interest, owned and operated 81 self storage properties containing approximately 5.7 million rentable square feet, configured in approximately 47,000 storage units and located across 13 states.

Results of Operations

When reviewing our results of operations it is important to consider the timing of acquisition and disposition activity and the internalization of our PRO structure. We acquired four self storage properties and disposed of ten self storage properties during the six months ended June 30, 2025. During the year ended December 31, 2024, we contributed 56 self storage properties to the 2024 Joint Venture, sold an additional 40 self storage properties and acquired seven self storage properties. As a result of these and other factors, we do not believe that our historical results of operations discussed and analyzed below are comparable or necessarily indicative of our future results of operations or cash flows.

The following discussion and analysis of the results of our operations and financial condition should be read in conjunction with the accompanying condensed consolidated financial statements in Item 1. Certain figures, such as interest rates and other percentages, included in this section have been rounded for ease of presentation. Percentage figures included in this section have not in all cases been calculated on the basis of such rounded figures but on the basis of such amounts prior to rounding. For this reason, percentage amounts in this section may vary slightly from those obtained by performing the same calculations using the figures in our condensed consolidated financial statements or in the associated text. Certain other amounts that appear in this section may similarly not sum due to rounding.

Total Revenue

Our total revenue, including management fees and other revenue, decreased by $1.6 million, or 0.8%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. This decrease in total revenue was attributable to a decrease in total portfolio average occupancy from 86.1% for the three months ended June 30, 2024 to 83.6% for the three months ended June 30, 2025 and to the sale of 11 self storage properties to unaffiliated third parties between April 1, 2024 and June 30, 2025. Average occupancy is calculated based on the average of the month-end occupancy immediately preceding the period presented and the month-end occupancies included in the respective period presented.

Rental Revenue

Rental revenue decreased by $4.5 million, or 2.6%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The decrease in rental revenue was attributable to a decrease in total portfolio average occupancy from 86.1% for the three months ended June 30, 2024, to 83.6% for the three months ended June 30, 2025 and to the sale of 11 self storage properties to unaffiliated third parties between April 1, 2024 and June 30, 2025. Annualized total portfolio rental revenues (including fees and net of any discounts and uncollectible customer amounts) divided by average occupied square feet ("average annualized rental revenue per occupied square foot") decreased from $15.59, for the three months ended June 30, 2024 to $15.56, or 0.2%, for the three months ended June 30, 2025.

Other Property-Related Revenue

Other property-related revenue represents ancillary income from our self storage properties, such as tenant insurance-related access fees and sales of storage supplies. Other property-related revenue increased by $0.2 million, or 3.3%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024.

Management Fees and Other Revenue

Management fees and other revenue, which includes revenue related to managing and operating the unconsolidated real estate ventures and other revenue from our tenant insurance programs, increased $2.7 million, or 28.4%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This increase was primarily attributable to increased property management fees resulting from the 2023 Joint Venture and the 2024 Joint Venture and an increase in tenant insurance activity upon our acquisition of certain rights related to certain former PROs’ tenant insurance-related programs during the year ended December 31, 2024.

Property Operating Expenses

Property operating expenses increased by $3.4 million, or 6.6%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. The increase in property operating expenses was primarily attributable to increases in marketing, repairs and maintenance, and property tax expense, partially offset by decreases in property operating expenses resulting from the sale of 11 self storage properties to unaffiliated third parties between April 1, 2024 and June 30, 2025.

General and Administrative Expenses

General and administrative expenses decreased by $3.4 million, or 20.9%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This result was primarily attributable to a decrease in management fees following the internalization of the PRO structure from $5.1 million for the three months ended June 30, 2024 to $1.4 million for the three months ended June 30, 2025.

Depreciation and Amortization

Depreciation and amortization increased $0.9 million, or 1.9%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This increase was primarily attributable to the incremental depreciation expense related to the 11 self storage properties acquired between April 1, 2024 and June 30, 2025.

Other

Other expenses increased $1.1 million, or 33.3%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This increase was primarily attributable to increases in administrative costs relating to our tenant insurance programs, due to an increase in related activity upon our acquisition of certain rights related to certain former PROs' tenant insurance-related programs during the year ended December 31, 2024.

Interest Expense

Interest expense increased $4.0 million, or 10.9%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. The increase in interest expense was primarily attributable to interest rate swaps that matured in August 2024 and February 2025. The maturity of these swaps, which effectively fixed SOFR at a lower rate than the prevailing market rate, resulted in an increase in the amount of debt subject to variable interest rates (excluding variable-rate debt subject to interest rate swaps) outstanding from $222.0 million, as of June 30, 2024, to $403.9 million as of June 30, 2025.

Equity In Losses Of Unconsolidated Real Estate Ventures

Equity in losses of unconsolidated real estate ventures represents our share of earnings and losses incurred through our 25% ownership interests in the 2024 Joint Venture, the 2023 Joint Venture, the 2018 Joint Venture and the 2016 Joint Venture. During the three months ended June 30, 2025, we recorded $3.9 million of equity in losses from our unconsolidated real estate ventures compared to $4.4 million of losses for the three months ended June 30, 2024. The decrease was primarily attributable to a decrease in the non-cash impact of applying the HLBV method to the 2024 Joint Venture, which allocates income (loss) based on the change in each owners' claim on net assets upon a hypothetical liquidation of the underlying joint venture at book value as of June 30, 2025.

Acquisition and Integration Costs

Acquisition and integration costs increased $1.6 million for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This increase was primarily attributable to costs related to the internalization of the PRO structure.

Gain on Sale of Self Storage Properties

Gain on sale of self storage properties was $9.6 million, for the three months ended June 30, 2025, compared to $2.7 million for the three months ended June 30, 2024. The gain on sale of self storage properties was primarily attributable to the sale of eight self storage properties to third parties during the three months ended June 30, 2025, for net proceeds of $57.4 million.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests was $11.5 million for the three months ended June 30, 2025, compared to $15.2 million for the three months ended June 30, 2024.

Total Revenue

Our total revenue, including management fees and other revenue, decreased by $9.4 million, or 2.4%, for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. This decrease was primarily attributable to the contribution of 56 self storage properties to the 2024 Joint Venture and the sale of 50 self storage properties to unaffiliated third parties between January 1, 2024 and June 30, 2025. The decrease in total revenue was also attributable to a decrease in total portfolio average occupancy from 85.8% for the six months ended June 30, 2024 to 83.6% for the six months ended June 30, 2025. Average occupancy is calculated based on the average of the month-end occupancy immediately preceding the period presented and the month-end occupancies included in the respective period presented.

Rental Revenue

Rental revenue decreased by $15.4 million, or 4.4%, for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The decrease in rental revenue was primarily attributable to the contribution of 56 self storage properties to the 2024 Joint Venture and the sale of 50 self storage properties to unaffiliated third parties between January 1, 2024 and June 30, 2025. Average annualized rental revenue per occupied square foot decreased from $15.65, for the six months ended June 30, 2024 to $15.56, or 0.6%, for the six months ended June 30, 2025, driven primarily by decreased contractual lease rates for in-place tenants.

Other Property-Related Revenue

Other property-related revenue represents ancillary income from our self storage properties, such as tenant insurance-related access fees and sales of storage supplies. Other property-related revenue increased by $0.3 million, or 2.0%, for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.

Management Fees and Other Revenue

Management fees and other revenue, which includes revenue related to managing and operating the unconsolidated real estate ventures and other revenue from our tenant insurance programs, increased $5.8 million, or 31.0%, for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This increase was primarily attributable to increased property management fees resulting from the 2023 Joint Venture and the 2024 Joint Venture and an increase in tenant insurance activity upon our acquisition of certain rights related to certain former PROs’ tenant insurance-related programs during the year ended December 31, 2024.

Property Operating Expenses

Property operating expenses increased by $3.8 million, or 3.6%, for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. The increase in property operating expenses was primarily attributable to increases in marketing, repairs and maintenance, and property tax expense, partially offset by decreases in property operating expenses resulting from the contribution of 56 self storage properties to the 2024 Joint Venture and the sale of 50 self storage properties to unaffiliated third parties between January 1, 2024 and June 30, 2025.

General and Administrative Expenses

General and administrative expenses decreased by $5.9 million, or 18.6%, for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This result was primarily attributable to a decrease in management fees following the internalization of the PRO structure from $10.1 million for the six months ended June 30, 2024 to $2.8 million for the six months ended June 30, 2025.

Depreciation and Amortization

Depreciation and amortization increased $1.7 million, or 1.8%, for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This increase was primarily attributable to the incremental depreciation expense related to the 11 self storage properties acquired between January 1, 2024 and June 30, 2025.

Other

Other expenses increased $2.1 million, or 30.7%, for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This increase was primarily attributable to increases in administrative costs relating to our tenant insurance programs, due to an increase in related activity upon our acquisition of certain rights related to certain former PROs’ tenant insurance-related programs during the year ended December 31, 2024.

Interest Expense

Interest expense increased $6.4 million, or 8.5%, for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. The increase in interest expense was primarily attributable to interest rate swaps that matured in August 2024 and February 2025. The maturity of these swaps, which effectively fixed SOFR at a lower rate than the prevailing market rate, resulted in an increase in the amount of debt subject to variable interest rates (excluding variable-rate debt subject to interest rate swaps) outstanding from $222.0 million, as of June 30, 2024, to $403.9 million as of June 30, 2025.

Equity In Losses Of Unconsolidated Real Estate Ventures

Equity in losses of unconsolidated real estate ventures represents our share of earnings and losses incurred through our 25% ownership interests in the 2024 Joint Venture, the 2023 Joint Venture, the 2018 Joint Venture and the 2016 Joint Venture. During the six months ended June 30, 2025, we recorded $9.7 million of equity in losses from our unconsolidated real estate ventures compared to $6.1 million of losses for the six months ended June 30, 2024. The increase was primarily attributable to an increase in the non-cash impact of applying the HLBV method to the 2024 Joint Venture, which allocates income (loss) based on the change in each owners' claim on net assets upon a hypothetical liquidation of the underlying joint venture at book value as of June 30, 2025.

Acquisition and Integration Costs

Acquisition and integration costs increased $3.5 million for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This increase was primarily attributable to costs related to the internalization of the PRO structure.

Gain on Sale of Self Storage Properties

Gain on sale of self storage properties was $11.0 million, for the six months ended June 30, 2025, compared to $63.8 million for the six months ended June 30, 2024. The gain on sale of self storage properties was primarily attributable to the sale of ten self storage properties to third parties during the six months ended June 30, 2025, for net proceeds of $67.1 million.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests was $18.0 million for the six months ended June 30, 2025, compared to $51.3 million for the six months ended June 30, 2024. The decrease was primarily attributable to the decrease in net income driven by larger gains on the sale of self storage properties recognized in the six months ended June 30, 2024.

Non-GAAP Financial Measures

FFO and Core FFO

Funds from operations, or FFO, is a widely used performance measure for real estate companies and is provided here as a supplemental measure of our operating performance. The December 2018 Nareit Funds From Operations White Paper - 2018 Restatement defines FFO as net income (as determined under GAAP), excluding: real estate depreciation and amortization, gains and losses from the sale of certain real estate assets, gains and losses from change in control, mark-to-market changes in value recognized on equity securities, impairment write-downs of certain real estate assets and impairment of investments in entities when it is directly attributable to decreases in the value of depreciable real estate held by the entity, and after adjusting equity in earnings (losses) to reflect our share of FFO in unconsolidated real estate ventures. Distributions declared on subordinated performance units and DownREIT subordinated performance units represented our allocation of FFO to noncontrolling interests held by subordinated performance unitholders and DownREIT subordinated performance unitholders. For purposes of calculating FFO attributable to common shareholders, OP unitholders, and LTIP unitholders, we exclude distributions declared on preferred shares and preferred units, and, prior to the internalization of the PRO structure, subordinated performance units and DownREIT subordinated performance units. We define Core FFO as FFO, as further adjusted to eliminate the impact of certain items that we do not consider indicative of our core operating performance. These further adjustments consist of acquisition costs, integration costs, executive severance costs, gains on debt forgiveness, gains (losses) on early extinguishment of debt, casualty-related expenses, losses, and related recoveries and adjustments for unconsolidated partnerships and joint ventures.

Management uses FFO and Core FFO as key performance indicators in evaluating the operations of our properties. Given the nature of our business as a real estate owner and operator, we consider FFO and Core FFO as key supplemental measures of our operating performance that are not specifically defined by GAAP. We believe that FFO and Core FFO are useful to management and investors as a starting point in measuring our operational performance because FFO and Core FFO exclude various items included in net income (loss) that do not relate to or are not indicative of our operating performance such as gains (or losses) from sales of self storage properties and depreciation, which can make periodic and peer analyses of operating performance more difficult. Our computation of FFO and Core FFO may not be comparable to FFO reported by other REITs or real estate companies.

FFO and Core FFO should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues, operating income and net income (loss). FFO and Core FFO do not represent cash generated from operating activities determined in accordance with GAAP and are not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO and Core FFO should be compared with our reported net income (loss) and considered in addition to cash flows computed in accordance with GAAP, as presented in our condensed consolidated financial statements.

The following table presents a reconciliation of net income to FFO and Core FFO for the three and six months ended June 30, 2025 and 2024 (dollars in thousands, except per share and unit amounts):

(1)			Amounts represent distributions declared for subordinated performance unitholders and DownREIT subordinated performance unitholders for the periods presented.
(2)			Executive severance costs relate to the three months ended June 30, 2024 and are recorded within the line items "General and administrative expenses" and "Non-operating income" in our consolidated statements of operations. Integration costs relate to expenses incurred as a part of the internalization of the PRO structure.
(3)			We combine OP units and DownREIT OP units with common shares because, after the applicable lock-out periods, OP units in our operating partnership are redeemable for cash or, at our option, exchangeable for common shares on a one-for-one basis and DownREIT OP units are also redeemable for cash or, at our option, exchangeable for OP units in our operating partnership on a one-for-one basis, subject to certain adjustments in each case. LTIP units may also, under certain circumstances, be convertible into or exchangeable for common shares (or other units that are convertible into or exchangeable for common shares). All subordinated performance units and DownREIT subordinated performance units were converted into OP units on July 1, 2024, in connection with the internalization of the PRO structure. See Note 1 to the following table for additional discussion of subordinated performance units, DownREIT subordinated performance units, and LTIP units in the calculation of FFO and Core FFO per share and unit.

The following table presents a reconciliation of earnings per share - diluted to FFO and Core FFO per share and unit for the three and six months ended June 30, 2025 and 2024:

Core FFO per share and unit	$	0.55	$	0.62	$	1.09	$	1.22


(1)			Adjustment accounts for the difference between the weighted average number of shares used to calculate diluted earnings per share and the weighted average number of shares used to calculate FFO and Core FFO per share and unit. Diluted earnings per share is calculated using the two-class method for the company's restricted common shares and the treasury stock method for certain unvested LTIP units, and assumes the conversion of vested LTIP units into OP units on a one-for-one basis and the hypothetical conversion of subordinated performance units and DownREIT subordinated performance units into OP units, even though such units may have only been convertible into OP units (i) after a lock-out period and (ii) upon certain events or conditions. All outstanding subordinated performance units and DownREIT subordinated performance units were converted into OP units on July 1, 2024, in connection with the internalization of the PRO structure. The computation of weighted average shares and units for FFO and Core FFO per share and unit includes all restricted common shares and LTIP units that participate in distributions and excludes all subordinated performance units and DownREIT subordinated performance units because their effect has been accounted for through the allocation of FFO to the related unitholders based on distributions declared.
(2)			Represents the effect of adjusting the numerator to consolidated net income (loss) prior to GAAP allocations for noncontrolling interests, after deducting preferred share and unit distributions, and before the application of the two-class method and treasury stock method, as described in Note 1.

Net Operating Income

Net operating income, or NOI, represents rental revenue plus other property-related revenue less property operating expenses. NOI is not a measure of performance calculated in accordance with GAAP.

We believe NOI is useful to investors in evaluating our operating performance because:

•NOI is one of the primary measures used by our management to evaluate the economic productivity of our properties, including our ability to lease our properties, increase pricing and occupancy and control our property operating expenses;

•NOI is widely used in the real estate industry and the self storage industry to measure the performance and value of real estate assets without regard to various items included in net income that do not relate to or are not indicative of operating performance, such as depreciation and amortization, which can vary depending upon accounting methods, the book value of assets, and the impact of our capital structure; and

•We believe NOI helps our investors to meaningfully compare the results of our operating performance from period to period by removing the impact of our capital structure (primarily interest expense on our outstanding indebtedness) and depreciation of the cost basis of our assets from our operating results.

There are material limitations to using a non-GAAP measure such as NOI, including the difficulty associated with comparing results among more than one company and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income (loss). We compensate for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with our analysis of net income (loss). NOI should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues and net income (loss).

Three Months Ended June 30, 2025 compared to the Three Months Ended June 30, 2024

As of June 30, 2025, our same store portfolio consisted of 771 self storage properties. Our same store portfolio is defined as those properties owned and operated since the first day of the earliest year presented, excluding any properties sold, expected to be sold or subject to significant changes such as expansions or casualty events which cause the portfolio's year-over-year operating results to no longer be comparable. The following table illustrates the changes in rental revenue, other property-related revenue, and property operating expenses, for the three months ended June 30, 2025 compared to the three months ended June 30, 2024 (dollars in thousands):

Certain payroll and related costs associated with the former PRO portfolios were not reflected as property-level expenses in 2024 under the management of the former PROs. Such costs are reflected in property operating expenses in 2025 under our management. For purposes of comparable same store reporting, we have included the specific 2024 expense amounts for the same store portfolio in the relevant periods. This line item is presented in order to reconcile total property operating expenses to previously reported figures.

Rental Revenue

Same store portfolio rental revenues decreased $5.3 million, or 3.1%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. This decrease in same store portfolio rental revenue was driven primarily by a decrease in average occupancy from 86.6% for the three months ended June 30, 2024 to 84.2% for the three months ended June 30, 2025. Average annualized same store rental revenue per occupied square foot decreased from $15.72 to $15.68, or 0.3%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024.

Other Property-Related Revenue

Same store portfolio other property-related revenue was relatively consistent for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024.

Property Operating Expenses

Same store portfolio property operating expenses increased $2.3 million, or 4.6%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase in same store property operating expenses was a result of increases in marketing, repairs and maintenance and property tax expense, partially offset by decreases in personnel costs during the three months ended June 30, 2025.

Six Months Ended June 30, 2025 compared to the Six Months Ended June 30, 2024

Our consolidated NOI shown in the table above does not include our proportionate share of NOI for our unconsolidated real estate ventures. For additional information about the 2016 Joint Venture, the 2018 Joint Venture, the 2023 Joint Venture and the 2024 Joint Venture see Note 5 to the condensed consolidated financial statements in Item 1.

EBITDA and Adjusted EBITDA

We define EBITDA as net income (loss), as determined under GAAP, plus interest expense, loss on early extinguishment of debt, income taxes, depreciation and amortization expense and the Company's share of unconsolidated real estate venture depreciation and amortization. We define Adjusted EBITDA as EBITDA plus acquisition costs, integration costs, executive severance costs, equity-based compensation expense, losses on sale of properties, impairment of long-lived assets and casualty-related expenses, losses and recoveries, minus gains on sale of properties and debt forgiveness, and after adjustments for unconsolidated partnerships and joint ventures, including the removal of the non-cash effect of applying HLBV for purposes of allocating GAAP net income (loss) for the 2024 Joint Venture. These further adjustments eliminate the impact of items that we do not consider indicative of our core operating performance. In evaluating EBITDA and Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of EBITDA and Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We present EBITDA and Adjusted EBITDA because we believe they assist investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. EBITDA and Adjusted EBITDA have limitations as an analytical tool. Some of these limitations are:

•EBITDA and Adjusted EBITDA do not reflect our cash expenditures, or future requirements, for capital expenditures, contractual commitments or working capital needs;

•EBITDA and Adjusted EBITDA do not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debts;

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect any cash requirements for such replacements;

•Adjusted EBITDA excludes equity-based compensation expense, which is and will remain a key element of our overall long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period;

•EBITDA and Adjusted EBITDA do not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; and

•other companies in our industry may calculate EBITDA and Adjusted EBITDA differently than we do, limiting their usefulness as comparative measures.

We compensate for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with our analysis of net income (loss). EBITDA and Adjusted EBITDA should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues and net income (loss).

The following table presents a reconciliation of net income to EBITDA and Adjusted EBITDA for the periods presented (dollars in thousands):

Liquidity and Capital Resources

Liquidity Overview

Liquidity is the ability to meet present and future financial obligations. Our primary source of liquidity is cash flow from our operations. Additional sources are proceeds from dispositions of self storage properties (including contributions to our joint ventures), equity and debt offerings, debt financings including additional borrowing capacity under the credit facility, and expansion options available under the 2028 Term Loan Facility, the June 2029 Term Loan Facility, and our credit facility.

Our short-term liquidity requirements consist primarily of property operating expenses, property acquisitions, capital expenditures, general and administrative expenses and principal and interest on our outstanding indebtedness. A further short-term liquidity requirement relates to distributions to our common and preferred shareholders and holders of preferred units, OP units, LTIP units and DownREIT OP units. We expect to fund short-term liquidity requirements from our operating cash flow, cash on hand and borrowings under our credit facility.

Our long-term liquidity needs consist primarily of the repayment of debt, property acquisitions, and capital expenditures. We acquire properties through the use of cash, preferred units, and OP units in our operating partnership or DownREIT partnerships. We expect to meet our long-term liquidity requirements with operating cash flow, cash on hand, secured and unsecured indebtedness, and the issuance of equity and debt securities.

The availability of credit and its related effect on the overall economy may affect our liquidity and future financing activities, both through changes in interest rates and access to financing. Our ability to access capital on favorable terms as well as to use cash from operations to continue to meet our liquidity needs, all of which are highly uncertain and cannot be predicted, could be affected by various risks and uncertainties. We believe that, as a publicly-traded REIT, we will have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional debt and the issuance of debt and additional equity securities. However, we cannot assure you that this will be the case.

Cash Flows

At June 30, 2025, we had $26.1 million in cash and cash equivalents and $1.8 million of restricted cash, a decrease in cash and cash equivalents of $24.3 million and an increase in restricted cash of $1.5 million from December 31, 2024. Restricted cash primarily consists of escrowed funds deposited with financial institutions resulting from property sales for which we elected to purchase replacement property in accordance with Section 1031 of the Code, and for real estate taxes, insurance, and other reserves for capital improvements in accordance with our loan agreements. The following discussion relates to changes in cash due to operating, investing, and financing activities, which are presented in our condensed consolidated statements of cash flows included in Item 1 of this report.

Operating Activities

Cash provided by our operating activities was $165.5 million for the six months ended June 30, 2025 compared to $177.2 million the six months ended June 30, 2024. Our operating cash flow decreased primarily due to a decrease in rental revenue primarily driven by the contribution of 56 self storage properties to the 2024 Joint Venture and the sale of 50 self storage properties to unaffiliated third parties between January 1, 2024 and June 30, 2025.

Investing Activities

Cash provided by investing activities was $25.5 million for the six months ended June 30, 2025 compared to $544.7 million of cash provided by investing activities for the six months ended June 30, 2024. The primary source of cash for the six months ended June 30, 2025 was the $66.1 million of proceeds from the sale of ten self storage properties to third parties, partially offset by our acquisition of four self storage properties and two properties that are considered annexes to existing properties and expenditures for corporate furniture and equipment.

Capital expenditures totaled $11.8 million and $9.1 million during the six months ended June 30, 2025 and 2024, respectively. We generally fund post-acquisition capital additions from cash provided by operating activities.

We categorize our capital expenditures broadly into three primary categories:

•recurring capital expenditures, which represent the portion of capital expenditures that are deemed to replace the consumed portion of acquired capital assets and extend their useful life;

•value enhancing capital expenditures, which represent the portion of capital expenditures that are made to enhance the revenue and value of an asset from its original purchase condition; and

•acquisitions capital expenditures, which represent the portion of capital expenditures capitalized during the current period that were identified and underwritten prior to a property's acquisition.

A summary of the capital expenditures for these categories, along with a reconciliation of the total for these categories to the capital expenditures reported in the accompanying condensed consolidated statements of cash flows for the six months ended June 30, 2025 and 2024, are presented below (dollars in thousands):


	Six Months Ended June 30,
	2025		2024
Recurring capital expenditures	$	8,701	$	5,796
Value enhancing capital expenditures	1,927		2,172
Acquisitions capital expenditures	1,042		1,549
Total capital expenditures	11,670		9,517
Change in accrued capital spending	178		(433)
Capital expenditures per statement of cash flows	$	11,848	$	9,084

Financing Activities

Cash used in our financing activities was $213.9 million for the six months ended June 30, 2025 compared to $742.5 million of cash used in financing activities for the six months ended June 30, 2024. Our primary uses of financing cash flows for the six months ended June 30, 2025 were for principal payments on existing debt of $359.5 million (which included $358.4 million of principal repayments under the Revolver and $1.1 million of scheduled fixed rate mortgage principal amortization payments), distributions to common shareholders of $87.2 million, distributions to noncontrolling interests of $67.4 million and distributions to preferred shareholders of $10.2 million. Our sources of financing cash flows for the six months ended June 30, 2025 primarily consisted of $314.0 million of borrowings under our Revolver.

Credit Facility and Term Loan Facilities

As of June 30, 2025, our credit facility provided for total borrowings of $1.355 billion, consisting of the following components: (i) a Revolver which provides for a total borrowing commitment up to $950.0 million, whereby we may borrow, repay and re-borrow amounts under the Revolver, (ii) a $275.0 million Term Loan D and (iii) a $130.0 million Term Loan E. The Revolver is set to mature in January 2027; provided that we may elect up to two times to extend the maturity by six months each up to January 2028 by paying an extension fee for each such election of 0.0625% of the total borrowing commitment thereunder at the time of extension and meeting other customary conditions with respect to compliance. The Term Loan D matures in July 2026 and the Term Loan E matures in March 2027. The Revolver, Term Loan D and Term Loan E are not subject to any scheduled reduction or amortization payments prior to maturity. As of June 30, 2025, we had an expansion option under the credit facility, which, if exercised in full, would provide for a total borrowing capacity of $1.900 billion.

As of June 30, 2025, $275.0 million was outstanding under the Term Loan D with an effective interest rate of 4.11% and $130.0 million was outstanding under the Term Loan E with an effective interest rate of 5.04%. As of June 30, 2025, we would have had the capacity to borrow remaining Revolver commitments of $544.1 million while remaining in compliance with the credit facility's financial covenants.

We have a 2028 Term Loan Facility that matures in December 2028 and is separate from the credit facility in an aggregate amount of $75.0 million. As of June 30, 2025 the entire amount was outstanding under the 2028 Term Loan Facility with an effective interest rate of 4.17%. We have an expansion option under the 2028 Term Loan Facility, which, if exercised in full, would provide for total borrowings in an aggregate amount up to $125.0 million.

We have an April 2029 Term Loan Facility that matures in April 2029 and is separate from the credit facility and 2028 Term Loan Facility in an aggregate amount of $100.0 million. As of June 30, 2025 the entire amount was outstanding under the April 2029 Term Loan Facility with an effective interest rate of 3.77%.

We have a June 2029 Term Loan Facility that matures in June 2029 and is separate from the credit facility, 2028 Term Loan Facility, and April 2029 Term Loan Facility in an aggregate amount of $285.0 million. As of June 30, 2025, the June 2029 Term Loan Facility had an effective interest rate of 5.07%. We have an expansion option under the June 2029 Term Loan Facility, which, if exercised in full, would provide for total borrowings in an aggregate amount up to $300.0 million.

During the three months ended June 30, 2025, we executed amendments to the agreements with the respective lenders for each of our 2028 Term Loan Facility, April 2029 Term Loan Facility and June 2029 Term Loan Facility, aligning the margin component of the respective interest rates with the applicable margin for our Term Loan D and Term Loan E as defined under the credit facility. As a result, the interest rates on each of the 2028 Term Loan Facility, the April 2029 Term Loan Facility and the June 2029 Term Loan Facility decreased during the second quarter.

Off-Balance Sheet Arrangements

Except as disclosed in the notes to our financial statements, as of June 30, 2025, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purposes entities, which typically are established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, except as disclosed in the notes to our financial statements, as of June 30, 2025, we have not guaranteed any obligations of unconsolidated entities, nor made any commitments to provide funding to any such entities, that creates any material exposure to any financing, liquidity, market or credit risk.

Seasonality

The self storage business is subject to minor seasonal fluctuations. A greater portion of revenues and profits are generally realized from May through September. Historically, our highest level of occupancy has typically been in July, while our lowest level of occupancy has typically been in February. Results for any quarter may not be indicative of the results that may be achieved for the full fiscal year.

Supplemental U.S. Federal Income Tax Considerations

The following discussion supplements and updates the disclosures under the heading "U.S. Federal Income Tax Considerations" in the prospectus dated March 7, 2024, contained in our Registration Statement on Form S-3 (File No. 333-277750) filed with the SEC on March 7, 2024 (the "Existing Tax Disclosure"). Capitalized terms herein that are not otherwise defined shall have the same meaning as when used in the Existing Tax Disclosure.

On July 4, 2025, H.R. 1, informally known as the One Big Beautiful Bill Act (the "OBBB"), was enacted. The OBBB makes major changes to the Code, including some provisions of the Code that affect the taxation of REITs and their investors. In particular:

•For taxable years beginning on or after January 1, 2026, the OBBB relaxed the REIT asset test requirement with respect to taxable REIT subsidiaries, providing that not more than 25% (relaxed from 20%) of the gross value of a REIT’s assets may be represented by securities of one or more taxable REIT subsidiaries.

•The OBBB permanently extended the pass-through qualified business income deduction, generally allowing individuals to deduct 20% of the aggregate amount of ordinary REIT dividends distributed by a REIT. This deduction was due to expire for tax years beginning on or after January 1, 2026.

•The OBBB permanently extended the maximum U.S. federal income tax rate of 37%, which applies to ordinary income recognized by individuals and other non-corporate U.S. stockholders, for tax years beginning on or after January 1, 2026.

To the extent the information set forth in the Existing Tax Disclosure is inconsistent with this supplemental information, this supplemental information supersedes the information in the Existing Tax Disclosure. This supplemental information is provided on the same basis and subject to the same qualifications as are set forth in the first six paragraphs of the Existing Tax Disclosure as if those paragraphs were set forth in this Quarterly Report on Form 10-Q.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk refers to the risk of loss from adverse changes in market prices and interest rates. Our future income, cash flows, and fair values of financial instruments are dependent upon prevailing market interest rates. The primary market risk to which we believe we are exposed is interest rate risk. Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, and other factors beyond our control. We use interest rate swaps to moderate our exposure to interest rate risk by effectively converting the interest on variable rate debt to a fixed rate. We make limited use of other derivative financial instruments and we do not use them for trading or other speculative purposes.

As of June 30, 2025, we had $403.9 million of debt subject to variable interest rates (excluding variable-rate debt subject to interest rate swaps). If our reference rates (SOFR) were to increase or decrease by 100 basis points, the increase or decrease in interest expense on the variable-rate debt (excluding variable-rate debt subject to interest rate swaps) would decrease or increase future earnings and cash flows by approximately $4.0 million annually.

Interest rate risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

ITEM 4. Controls and Procedures

Disclosure Controls and Procedures

The Company's management, with the participation of the Company's chief executive officer and chief financial officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the chief executive officer and chief financial officer concluded that the Company's disclosure controls and procedures, as of the end of the period covered by this report, are effective.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the six months ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in our periodic reports.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

We are not currently subject to any legal proceedings that we consider to be material.

ITEM 1A. Risk Factors

For a discussion of our potential risks and uncertainties, see the Company's Annual Report on Form 10-K for the year ended December 31, 2024 (the "2024 Form 10-K") filed with the SEC under the heading Item 1A. "Risk Factors" beginning on page 12, which is accessible on the SEC's website at www.sec.gov.

With the exception of the risk factor set forth below, which updates and supplements the risk factors disclosed in our 2024 Form 10-K, there have been no material changes to the risk factors disclosed in our 2024 Form 10-K.

Recent tariff actions by the U.S and other countries may have an adverse effect on our business, financial condition and results of operations.

The current U.S. administration has recently implemented tariffs on imports from a broad set of countries, including Canada, Mexico, European Union member states, Japan and China creating significant uncertainty about the future relationship between the United States and other countries with respect to these tariffs. In response to these tariffs, global trading partners have or are likely to impose their own tariffs. These developments, or the perception that any of them could occur, have resulted in significant financial market volatility and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between the impacted nations and the United States. Further effects of these tariffs cannot be predicted with certainty. Continued uncertainty surrounding trade policies and the potential for further tariff increases or the imposition of new tariffs may lead to a continuation or worsening of the impact of the tariffs on the financial markets. These trade actions and the widespread uncertainty and international tensions resulting therefrom may have a material adverse effect on our business, results of operations, ability to access capital, and financial condition and on the market price of our common stock.

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

Unregistered Sales of Equity Securities

During the three months ended June 30, 2025, the Company, in its capacity as general partner of its operating partnership, caused the operating partnership to issue 108,506 common shares to satisfy redemption requests from certain limited partners.

Following a specified lock up period after the date of issuance, the OP units issued by the operating partnership may be redeemed from time to time by holders for a cash amount per OP unit equal to the market value of an equivalent number of common shares. The Company has the right, but not the obligation, to assume and satisfy the redemption obligation of the operating partnership described above by issuing one common share in exchange for each OP unit tendered for redemption.

The Company may elect to report early the private placement of its common shares that may occur if the Company elects to assume the redemption obligation of the operating partnership as described above in the event that OP units are in the future tendered for redemption.

As of August 1, 2025, other than those OP units held by the Company, after reflecting the transactions described herein, 58,439,772 OP units were outstanding (including 850,663 outstanding LTIP units in the operating partnership and 5,769,214 outstanding DownREIT OP units, which are convertible into, or exchangeable for, OP units on a one-for-one basis, subject to certain conditions).

These issuances were exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended.

Issuer Purchases of Equity Securities

On July 11, 2022, the Company approved a share repurchase program authorizing the repurchase of up to $400.0 million of the Company's common shares, under which $256,892 of common shares remain available for repurchase. On December 1, 2023, the Company approved a new share repurchase program authorizing, but not obligating, the repurchase of up to $275.0 million of the Company's common shares, under which no common shares remain available for repurchase. On November 14, 2024, the Company approved a new share repurchase program authorizing, but not obligating, the repurchase of up to $350.0 million of the Company's common shares. During the three months ended June 30, 2025, certain of our employees surrendered common shares owned by them to satisfy their statutory minimum federal and state tax obligations associated with the vesting of restricted shares issued to them. The table below summarizes all of our repurchases of common shares during the three months ended June 30, 2025:


Period	Total number of shares purchased	Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Approximate Dollar Value of Shares that May Yet be Purchased under the Plans or Programs
April 1 - April 30, 2025	—	$	—	—	$	350,256,892
May 1 - May 31, 2025	—	—		—	350,256,892
June 1 - June 30, 2025(1)	523	34.12		—	350,256,892
Total/Weighted Average	523	$	34.12	—	$	350,256,892

(1)

The number of shares purchased represents restricted common shares surrendered by certain of our employees to satisfy their statutory minimum federal and state tax obligations associated with the vesting of restricted common shares issued to them. The price paid per share is based on the closing price of our common shares on June 10, 2025, which is the date of withholding.
