National Storage Affiliates Trust Reports Third Quarter 2024 Results

GREENWOOD VILLAGE, Colo. - (BUSINESS WIRE) - National Storage Affiliates Trust ("NSA" or the "Company") (NYSE: NSA) today reported the Company’s third quarter 2024 results.

Third Quarter 2024 Highlights

•Reported net income of $29.8 million for the third quarter of 2024, a decrease of 30.9% compared to the third quarter of 2023. Reported diluted earnings per share of $0.18 for the third quarter of 2024 compared to $0.26 for the third quarter of 2023.

•Reported core funds from operations ("Core FFO") of $83.9 million, or $0.62 per share and unit for the third quarter of 2024, a decrease of 7.5% per share compared to the third quarter of 2023.

•Reported a decrease in same store net operating income ("NOI") of 5.3% for the third quarter of 2024 compared to the same period in 2023, driven by a 3.5% decrease in same store total revenues and an increase of 1.2% in same store property operating expenses.

•Reported same store period-end occupancy of 85.6% as of September 30, 2024, a decrease of 270 basis points compared to September 30, 2023.

•One of the Company's unconsolidated real estate ventures acquired 18 self storage properties for approximately $147.9 million, in two separate transactions. The venture financed the acquisitions with capital contributions from the venture members, of which the Company contributed approximately $37.0 million.

•On September 5, 2024, the Company issued $350.0 million of senior unsecured notes with a weighted average interest rate of 5.6% and a weighted average maturity of 7.6 years in a private placement with institutional investors.

•As previously announced, effective July 1, 2024 (the "Closing Date"), the Company completed the internalization of its participating regional operator ("PRO") structure. As a result, the Company purchased the PROs' management contracts, and in some cases, their brand names, related intellectual property and certain rights related to the PROs' tenant insurance programs. As of the Closing Date, the Company will no longer pay supervisory and administrative fees or reimbursements under the previous agreements with the PROs. The Company continues to transition the majority of operations in a phased approach, which has begun and is expected to continue over the 12 month period following the Closing Date, and the Company has executed new asset management and property management agreements with a number of the PROs for all or a part of this transitionary period at newly negotiated management fees. In connection with the internalization, on July 1, 2024, 11,906,167 subordinated performance units and DownREIT subordinated performance units were converted into 17,984,787 OP units and DownREIT OP units.

David Cramer, President and Chief Executive Officer, commented, “We are pleased to announce that all our team members are safe following Hurricanes Helene and Milton. We hope that all affected by these storms remain safe, and we wish them the best as they work their way through the tough recovery period. While several of our facilities in the path of these storms experienced minor damage, largely impacting gates, roofs, and signage, all of our stores are back open for business. Separately, we made meaningful progress on our PRO internalization during the quarter, and I am very proud of our team’s effort on this significant transition for our company. Although still early, we are encouraged by the benefits that we are already starting to realize from implementing consistent marketing and pricing strategies while utilizing a centralized web platform.”

Mr. Cramer further commented, “Results for the quarter were in line with our expectations, as our team did a good job navigating the competitive operating environment while working on the PRO transition. On a positive note, the transaction environment is improving as we are seeing more deals come to market, with sellers becoming more realistic about pricing. As a result, we acquired 18 properties totaling almost $150 million through our 2023 Joint Venture during the quarter. Further, we opportunistically accessed the debt private placement market by issuing $350 million of senior unsecured notes with a weighted average coupon of 5.6%. The combination of an improving acquisition environment, more attractive cost of capital and the benefits from the internalization of the PRO structure, make us excited about what the future holds for NSA.”

(1)			Non-GAAP financial measures, including FFO, Core FFO and NOI, are defined in the Glossary in the supplemental financial information and, where appropriate, reconciliations of these measures and other non-GAAP financial measures to their most directly comparable GAAP measures are included in the Schedules to this press release and in the supplemental financial information.
(2)			Integration costs relate to expenses incurred as a part of the internalization of the PRO structure. Executive severance costs are recorded within the line items "General and administrative expenses" and "Non-operating (expense) income" in our consolidated statements of operations.
(3)			Casualty-related recoveries relate to casualty-related expenses incurred during 2022 and are recorded in the line item "Other" within operating expenses in our consolidated statements of operations.

Net income decreased $13.3 million for the third quarter of 2024 and increased $28.2 million for the nine months ended September 30, 2024 ("year-to-date") as compared to the same periods in 2023. The decrease in net income in the third quarter of 2024 was primarily due to a decrease in NOI, primarily driven by (i) the sale of 32 self storage properties to a third party in December 2023, (ii) the contribution of 56 self storage properties to a joint venture between a subsidiary of NSA and a subsidiary of Heitman Capital Management, LLC (the "2024 Joint Venture"), in the first quarter of 2024, and (iii) the sale of 40 self storage properties to third parties in the nine months ended September 30, 2024, partially offset by decreases in depreciation expense of $8.2 million and interest expense of $3.5 million. The year-to-date increase in net income resulted primarily from the gain on the sale of 40 self storage properties to third parties and 56 self storage properties contributed to the 2024 Joint Venture during the nine months ended September 30, 2024.

The decreases in FFO and Core FFO for the third quarter of 2024 and year-to-date were the result of a decrease in NOI of 14.5% and 12.4%, respectively, which were partially offset by a decrease in interest expense of 8.1% and 4.8%, respectively, as compared to the same periods in 2023. The decrease in FFO and Core FFO per share and unit for the third quarter of 2024 and year-to-date was largely driven by a decrease in same store NOI, partially offset by decreased management fees paid to former PROs, reflected within general and administrative expenses, following the internalization of the PRO structure.

Same Store Operating Results (776 Stores)

Average Annualized Rental Revenue Per Occupied Square Foot	$	15.67		$	15.81		(0.9)	%	$	15.72		$	15.61		0.7	%

Year-over-year same store total revenues decreased 3.5% for the third quarter of 2024 and 2.6% year-to-date as compared to the same period in 2023. The decrease for the third quarter was driven primarily by a 290 basis point decrease in average occupancy and a 0.9% decrease in average annualized rental revenue per occupied square foot. The year-to-date same store total revenue decrease was driven primarily by a 330 basis point decrease in average occupancy, partially offset by a 0.7% increase in average annualized rental revenue per occupied square foot. Markets which generated above portfolio average same store total revenue growth for the third quarter of 2024 include: San Juan, Wichita and Portland. Markets which generated below portfolio average same store total revenue growth for the third quarter of 2024 include: Atlanta, Phoenix and Sarasota-Bradenton.

Year-over-year same store property operating expenses increased 1.2% for the third quarter of 2024 and 3.4% year-to-date as compared to the same periods in 2023. The increases in the third quarter of 2024 primarily resulted from increases in property tax and insurance expense.

Investment Activity

During the third 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 18 self storage properties for approximately $147.9 million in two separate transactions. The 2023 Joint Venture financed the acquisitions with capital contributions from the venture members, of which the Company contributed approximately $37.0 million.

On July 1, 2024, as part of the internalization of the PRO structure, the Company paid consideration in cash and equity for the purchase of the PRO management contracts and, in some cases, their brand names and related intellectual property at a value of approximately $34.6 million and to acquire certain rights with respect to each PROs' tenant insurance programs at a value of approximately $60.3 million. The total cash and equity consideration for these transactions consisted of approximately $32.6 million in cash and the issuance of 1,548,866 OP units.

Balance Sheet

On September 5, 2024, NSA issued $75.0 million of 5.40% senior unsecured notes due September 5, 2028, $125.0 million of 5.55% senior unsecured notes due September 5, 2031 and $150.0 million of 5.74% senior unsecured notes due September 5, 2034 in a private placement with institutional investors. The Company used the proceeds from the private placement to repay its $325.0 million Tranche C term loan, which addresses all debt maturities in 2025, a portion of the revolving line of credit and for general corporate purposes.

Common Share Dividends

On August 15, 2024, NSA's Board of Trustees declared a quarterly cash dividend of $0.56 per common share. The third quarter 2024 dividend was paid on September 30, 2024 to shareholders of record as of September 13, 2024.

Non-GAAP Financial Measures & Glossary

This press release contains certain non-GAAP financial measures. These non-GAAP measures are presented because NSA's management believes these measures help investors understand NSA's business, performance and ability to earn and distribute cash to its shareholders by providing perspectives not immediately apparent from net income (loss). These measures are also frequently used by securities analysts, investors and other interested parties. 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. In addition, NSA's method of calculating these measures may be different from methods used by other companies, and, accordingly, may not be comparable to similar measures as calculated by other companies that do not use the same methodology as NSA. These measures, and other words and phrases used herein, are defined in the Glossary in the supplemental financial information and, where appropriate, reconciliations of these measures and other non-GAAP financial measures to their most directly comparable GAAP measures are included in the Schedules to this press release and in the supplemental financial information.

(1)			Amounts represent distributions declared for subordinated performance unitholders and DownREIT subordinated performance unitholders for the periods presented.
(2)			Integration costs relate to expenses incurred as a part of the internalization of the PRO structure. Executive severance costs are recorded within the line items "General and administrative expenses" and "Non-operating (expense) income" in our consolidated statements of operations.
(3)			Casualty-related recoveries relate to casualty-related expenses incurred during 2022 and are recorded in the line item "Other" within operating expenses in our consolidated statements of operations.
(4)			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(5) 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.

(5)			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 only be 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.
(6)			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(5).

(1)			Effective interest rate incorporates the stated rate plus the impact of interest rate cash flow hedges and discount and premium amortization, if applicable.
(2)			NSA may, at its election, extend the maturity date of the revolving line of credit to January 2028, subject to meeting customary conditions and payment of an extension fee.
(3)			For the $950 million revolving line of credit, the effective interest rate is calculated based on Daily Simple SOFR plus an applicable margin of 1.30% and a SOFR Index Adjustment of 0.10%, and excludes fees which range from 0.15% to 0.20% for unused borrowings. $225.0 million of the revolving line of credit is subject to interest rate swaps that mature in February 2025, which is reflected in the effective interest rate. $125.0 million of the Tranche E term loan is subject to interest rate swaps, the maturity of which extends through the Tranche E maturity.

(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;

•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 subordinated performance units, DownREIT subordinated performance units, preferred shares and preferred 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 total debt (inclusive of $3.3 million of fair value of debt adjustments and $13.9 million of debt issuance costs) less cash and cash equivalents, 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.

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 and the Company's PROs 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, NSA completed the internalization of its PRO structure. NSA continues to transition the majority of operations in a phased approach, which has begun and is expected to continue over the 12 month period following July 1, 2024.

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 PRO internalization, all 11,906,167 outstanding subordinated performance units and DownREIT subordinated performance units were converted into 17,984,787 OP units and DownREIT OP units.
