National Storage Affiliates Trust Reports Second Quarter 2025 Results
GREENWOOD VILLAGE, Colo. - (BUSINESS WIRE) - National Storage Affiliates Trust ("NSA" or the "Company") (NYSE: NSA) today reported the Company’s second quarter 2025 results.
Second Quarter 2025 Highlights
Reported net income of $31.0 million for the second quarter of 2025, a decrease of 4.1% compared to the second quarter of 2024. Reported diluted earnings per share of $0.19 for the second quarter of 2025 compared to $0.16 for the second quarter of 2024.
Reported core funds from operations ("Core FFO") of $74.4 million, or $0.55 per share for the second quarter of 2025, a decrease of 11.3% per share compared to the second quarter of 2024.
Reported a decrease in same store net operating income ("NOI") of 6.1% for the second quarter of 2025 compared to the same period in 2024, driven by a 3.0% decrease in same store total revenues and a 4.6% increase in same store property operating expenses.
Reported same store period-end occupancy of 85.0% as of June 30, 2025, a decrease of 220 basis points compared to June 30, 2024.
Acquired one wholly-owned self storage property and one property that is considered an annex to an existing property for approximately $11.4 million and one of NSA's unconsolidated real estate ventures acquired one self storage property for approximately $18.0 million during the second quarter of 2025.
Entered into an agreement to sell ten wholly-owned self storage properties for approximately $66.5 million. Eight of the properties were sold in June 2025, while the remaining two properties are classified as held for sale as of June 30, 2025 and were sold in July 2025.
Highlights Subsequent to Quarter-End
On July 22, 2025, one of NSA's unconsolidated real estate ventures acquired one self storage property for approximately $21.8 million. The venture financed the acquisition with capital contributions from the venture members, of which the Company contributed approximately $5.4 million.

David Cramer, President and Chief Executive Officer, commented, "During the second quarter, we realized sequential improvement from the prior quarter in the level of contract rate, occupancy and our rent roll-down spread. However, these positives were outweighed by continued softness in storage demand primarily driven by low existing home sales and ongoing supply pressure, especially in our Sunbelt markets, which also impacted the pace of realizing the benefits from the internalization of our PRO structure. Further, the elevated use of concessions during the quarter that drove rental volume has a near-term negative impact on revenues. The combination of these factors weighed on same store NOI and Core FFO results for the quarter and was the primary driver of our revised guidance ranges."
Mr. Cramer further commented, “While macroeconomic conditions have fallen short of our expectations, we are seeing positive momentum from our enhanced marketing and revenue management strategies, and we still expect to realize the full benefits from the internalization of our PRO structure."

(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.
Net income decreased $1.3 million for the second quarter of 2025 and $76.9 million for the six months ended June 30, 2025 ("year-to-date") as compared to the same periods in 2024. The year-to-date decrease in net income was primarily due to larger gains on the sale of self storage properties recognized in the first quarter of 2024. Additionally, the decrease in net income for both the second quarter of 2025 and year-to-date were a result of lower NOI, driven by property dispositions and negative same store NOI growth. These impacts for the second quarter of 2025 and year-to-date were partially offset by an increase in management fees and other revenue of $2.7 million and $5.8 million, respectively, and a decrease in general and administrative expenses of $3.4 million and $5.9 million, respectively, compared to the same periods in 2024.
The decrease in FFO and Core FFO per share and unit for the second quarter of 2025 and year-to-date was primarily driven by a decrease in same store NOI and an increase in interest expense. These impacts were partially offset by decreased management fees paid to former PROs, reflected within general and administrative expenses, following the internalization of the PRO structure.

Year-over-year same store total revenue decreased 3.0% for the second quarter of 2025 and 3.0% year-to-date as compared to the same periods in 2024. The decrease for the second quarter was driven primarily by a 240 basis point decrease in average occupancy and a 0.3% decrease in average annualized rental revenue per occupied square foot. The year-to-date same store total revenue decrease was driven primarily by a 210 basis point decrease in average occupancy and a 0.7% decrease in average annualized rental revenue per occupied square foot. Markets which generated above portfolio average same store total revenue growth include: Portland, Houston and San Juan, PR. Markets which generated below portfolio average same store total revenue growth include: Riverside-San Bernardino, Atlanta and Phoenix.
Year-over-year same store property operating expenses increased 4.6% for the second quarter of 2025 and 4.1% year-to-date as compared to the same periods in 2024. The increase was primarily driven by increases in marketing, repairs and maintenance, and property tax expense, partially offset by decreases in personnel and insurance costs.
Investment and Disposition Activity
During the second quarter, a joint venture between a subsidiary of NSA and a state pension fund advised by Heitman Capital Management, LLC (the "2023 Joint Venture") acquired one self storage property for approximately $18.0 million. The 2023 Joint Venture financed the acquisition with capital contributions from the venture members, of which NSA contributed approximately $4.5 million.
During the second quarter, NSA invested $11.4 million in the acquisition of one wholly-owned self storage property and one annex to an existing property, consisting of approximately 87,000 rentable square feet configured in approximately 700 storage units.
During the second quarter, NSA entered into an agreement to sell ten wholly-owned self storage properties consisting of approximately 663,000 rentable square feet configured in approximately 4,400 storage units for approximately $66.5 million, before disposition costs and credits. The agreement provides for separate disposition dates with eight self storage properties, consisting of approximately 580,000 rentable square feet configured in approximately 3,800 storage units for approximately $60.0 million, sold in June 2025, and two self storage properties, consisting of approximately 83,000 rentable square feet configured in approximately 600 storage units for approximately $6.5 million, sold in July 2025. NSA used the proceeds to pay down its revolving line of credit and for general corporate purposes.
Balance Sheet
As of June 30, 2025, NSA has approximately $544.1 million of available capacity on its $950.0 million revolving line of credit.
Common Share Dividends
On May 15, 2025, NSA's Board of Trustees declared a quarterly cash dividend of $0.57 per common share. The second quarter 2025 dividend was paid on June 30, 2025 to shareholders of record as of June 13, 2025.

Non-GAAP Financial Measures & Glossary

The presentations of FFO, Core FFO and NOI in this press release are not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

NSA combines OP units and DownREIT OP units with common shares because, after the applicable lock-out periods, OP units in the Company's operating partnership are redeemable for cash or, at NSA's option, exchangeable for common shares on a one-for-one basis and DownREIT OP units are also redeemable for cash or, at NSA's option, exchangeable for OP units in the Company's 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 footnote(4) 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.

(4)
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.
(5)
Represents the effect of adjusting the numerator to consolidated net income 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 footnote(4).

The Company's balance sheet at June 30, 2025 reflects 14,697,845 preferred shares of beneficial interest, which includes 5,668,128 Series B Preferred Shares issued and outstanding. We have reflected 13,638,162 preferred shares herein, which corresponds to the $341.0 million liquidation preference reflected on the balance sheet at June 30, 2025. As part of a 2023 property acquisition of 15 properties from one of the Company's former participating regional operators (the "Contributor"), the Company recorded a $26.1 million promissory note receivable from the Contributor, and the Contributor used the loan proceeds to acquire $26.1 million of OP equity. The promissory note bears interest at a rate equivalent to the dividends paid on 1,059,683 Series B Preferred Shares. As a result of these agreements, in accordance with GAAP, the $26.1 million promissory note receivable, interest income on the promissory note receivable, $26.1 million of Series B Preferred Shares value, and dividends on such Series B Preferred Shares have been offset for presentation purposes in the accompanying consolidated balance sheets and consolidated statements of operations.

(1)NSA's investment in its unconsolidated real estate ventures are recorded under the equity method of accounting. Under the equity method, NSA’s investments in unconsolidated real estate ventures are stated at cost and adjusted for NSA’s share of net earnings or losses and reduced by distributions.
(2)Values represent entire unconsolidated real estate ventures at 100%, not NSA's proportionate share. NSA's ownership in each of the unconsolidated real estate ventures is 25%. The operating agreements of the unconsolidated real estate ventures provide for the distribution of net cash flow to the unconsolidated real estate ventures' investors no less than monthly, generally in proportion to the investors’ respective ownership interests, subject to a promoted distribution to NSA upon the achievement of certain performance benchmarks by the non-NSA investor.

Glossary
This Earnings Release and Supplemental Financial Information includes certain financial and operating measures used by NSA management that are not calculated in accordance with accounting principles generally accepted in the United States, or GAAP. NSA's definitions and calculations of these non-GAAP financial and operating measures and other terms may differ from the definitions and methodologies used by other real estate companies and, accordingly, may not be comparable. These non-GAAP financial and operating measures should not be considered an alternative to GAAP net income or any other GAAP measurement of performance and should not be considered an alternative measure of liquidity.
AVERAGE ANNUALIZED RENTAL REVENUE PER OCCUPIED SQUARE FOOT: Average annualized rental revenue per occupied square foot is computed by dividing annualized rental revenue (including fees and net of any discounts and uncollectible customer amounts) by average occupied square feet.
AVERAGE OCCUPANCY: 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.
CAPITAL EXPENDITURES DEFINITIONS
ACQUISITIONS CAPITAL EXPENDITURES: Acquisitions capital expenditures represents the portion of capital expenditures capitalized during the current period that were identified and underwritten prior to a property's acquisition.
RECURRING CAPITAL EXPENDITURES: Recurring capital expenditures represents the portion of capital expenditures that are deemed to replace the consumed portion of acquired capital assets and extend their useful lives.
VALUE ENHANCING CAPITAL EXPENDITURES: Value enhancing capital expenditures represents the portion of capital expenditures that are made to enhance the revenue and value of an asset from its original purchase condition.
EBITDA: NSA defines 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. NSA defines 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 hypothetical liquidation at book value (HLBV) for purposes of allocating GAAP net income (loss) for the 2024 Joint Venture. These further adjustments eliminate the impact of items that the Company does not consider indicative of its core operating performance. In evaluating EBITDA and Adjusted EBITDA, you should be aware that in the future the Company may incur expenses that are the same as or similar to some of the adjustments in this presentation. NSA's presentation of EBITDA and Adjusted EBITDA should not be construed as an inference that its future results will be unaffected by unusual or non-recurring items.
NSA presents EBITDA and Adjusted EBITDA because the Company believes they assist investors and analysts in comparing the Company's performance across reporting periods on a consistent basis by excluding items that the Company does not believe are indicative of its 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 the Company's 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 the Company's 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 the Company's overall long-term incentive compensation package, although the Company excludes it as an expense when evaluating its ongoing operating performance for a particular period;
24

image0a93a.jpg
EBITDA and Adjusted EBITDA do not reflect the impact of certain cash charges resulting from matters the Company considers not to be indicative of its ongoing operations; and
other companies in NSA's industry may calculate EBITDA and Adjusted EBITDA differently than NSA does, limiting their usefulness as comparative measures.
NSA compensates for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with the Company's 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).
FUNDS FROM OPERATIONS: Funds from operations, or FFO, is a widely used performance measure for real estate companies and is provided here as a supplemental measure of the Company's 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 the Company's share of FFO in unconsolidated real estate ventures. Distributions declared on subordinated performance units and DownREIT subordinated performance units represent NSA's 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, NSA excludes 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. NSA defines CORE FFO as FFO, as further adjusted to eliminate the impact of certain items that the Company does not consider indicative of its 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 after adjustments for unconsolidated partnerships and joint ventures.
Management uses FFO and Core FFO as key performance indicators in evaluating the operations of NSA's properties. Given the nature of NSA's business as a real estate owner and operator, the Company considers FFO and Core FFO as key supplemental measures of its operating performance that are not specifically defined by GAAP. NSA believes that FFO and Core FFO are useful to management and investors as a starting point in measuring the Company's 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 the Company's 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. NSA's 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 NSA's ability to make cash distributions. NSA believes that to further understand the Company's performance, FFO and Core FFO should be compared with the Company's reported net income (loss) and considered in addition to cash flows computed in accordance with GAAP, as presented in the Company's consolidated financial statements.
HYPOTHETICAL LIQUIDATION AT BOOK VALUE METHOD OF UNCONSOLIDATED REAL ESTATE VENTURE: Subject to achieving certain performance benchmarks by the non-NSA investor, the distribution rights and priorities set forth in the 2024 Joint Venture agreement may differ from what is reflected by the underlying percentage ownership interest of the venture. Accordingly, NSA allocates GAAP income (loss) for its 2024 Joint Venture utilizing the hypothetical liquidation at book value ("HLBV") method, in which NSA allocates income or loss based on the change in each owners' claim on the net assets of the venture at period end assuming the liquidation of the underlying book value of the venture after adjusting for any distributions or contributions made during such period.
NET DEBT TO ANNUALIZED CURRENT QUARTER ADJUSTED EBITDA: NSA calculates net debt to Adjusted EBITDA as debt financing less cash and cash equivalents (both as reflected on the consolidated balance sheet), divided by annualized current quarter Adjusted EBITDA.
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.
25

image0a93a.jpg
NSA believes NOI is useful to investors in evaluating the Company's operating performance because:
NOI is one of the primary measures used by NSA's management to evaluate the economic productivity of the Company's properties, including the Company's ability to lease its properties, increase pricing and occupancy and control the Company's 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 NSA's capital structure; and
NSA believes NOI helps the Company's investors to meaningfully compare the results of its operating performance from period to period by removing the impact of the Company's capital structure (primarily interest expense on the Company's outstanding indebtedness) and depreciation of the cost basis of NSA's assets from its 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 the Company's net income (loss). NSA compensates for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with the Company's 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).
NON-SAME STORE PORTFOLIO: Non-same store portfolio comprises those properties that do not meet the Same Store portfolio property definition. 
OPERATING PARTNERSHIP UNITS:  Operating partnership units, or OP Units, are Class A common units of limited partner interest in the Company's operating partnership which are economically equivalent to NSA's common shares. NSA also owns certain of the Company's self storage properties through other consolidated subsidiaries of the Company's operating partnership, which the Company refers to as "DownREIT partnerships." The DownREIT partnerships issue certain units of limited partner or limited liability company interest that are intended to be economically equivalent to the Company's OP units, which the Company defines as DOWNREIT OPERATING PARTNERSHIP UNIT EQUIVALENTS, or DownREIT OP units.
PROs: Participating regional operators, or "PROs", were NSA's experienced regional self storage operators with local operational focus and expertise. 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.
RENTABLE SQUARE FEET: Rentable square feet includes all enclosed self storage units but excludes commercial, residential, and covered parking space.
SAME STORE PORTFOLIO: NSA's same store portfolio is defined as those properties owned and operated on a stabilized basis since the first day of the earliest year presented. The Company considers a property to be stabilized once it has achieved an occupancy rate that is representative of similar properties in the applicable market. NSA excludes 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.
SUBORDINATED PERFORMANCE UNITS:  Subordinated performance units, or SP Units, were Class B common units of limited partner interest in the Company's operating partnership. SP units, which were linked to the performance of specific contributed portfolios, were intended to incentivize the Company's former PROs to drive operating performance and support the sustainability of the operating cash flow generated by the contributed self storage properties that the PROs continued to manage on NSA's behalf. Because subordinated performance unit holders received distributions only after portfolio-specific minimum performance thresholds were satisfied, the Company believed SP units played a key role in aligning the interests of the Company's former PROs with NSA and the Company's shareholders. The DownREIT partnerships also issued units of limited partner interest that were intended to be economically equivalent to the Company's SP units, which the Company defines as DOWNREIT SUBORDINATED PERFORMANCE UNIT EQUIVALENTS, or DownREIT SP units. Effective July 1, 2024, in connection with the internalization of the PRO structure, all 11,906,167 outstanding subordinated performance units and DownREIT subordinated performance units were converted into an aggregate of 17,984,787 OP units and DownREIT OP units.
