National Storage Affiliates Trust Reports Second Quarter 2024 Results

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

Second Quarter 2024 Highlights

•Reported net income of $32.3 million for the second quarter of 2024, a decrease of 29.0% compared to the second quarter of 2023. Reported diluted earnings per share of $0.16 for the second quarter of 2024 compared to $0.28 for the second quarter of 2023.

•Reported core funds from operations ("Core FFO") of $71.2 million, or $0.62 per share for the second quarter of 2024, a decrease of 8.8% per share compared to the second quarter of 2023.

•Reported a decrease in same store net operating income ("NOI") of 5.6% for the second quarter of 2024 compared to the same period in 2023, driven by a 2.8% decrease in same store total revenues and an increase of 4.8% in same store property operating expenses.

•Reported same store period-end occupancy of 87.0% as of June 30, 2024, a decrease of 280 basis points compared to June 30, 2023.

•Acquired three wholly-owned self storage properties for approximately $25.2 million during the second quarter of 2024.

•Repurchased 1,908,397 of the Company's common shares for approximately $71.6 million under the Company's previously announced share repurchase program.

Highlights Subsequent to Quarter-End

•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 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 plans to transition the majority of operations in a phased approach, which is expected to occur 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 converted into 17,984,787 OP units and DownREIT OP units.

•On July 29, 2024, the Company repaid in full the remaining $145.0 million of Term Loan Tranche B using the revolving line of credit.

•On July 30, 2024, a joint venture between a subsidiary of NSA and a state pension fund advised by Heitman Capital Management, LLC (the "2023 Joint Venture") acquired a portfolio of five self storage properties for approximately $71.9 million. The venture financed the acquisition with capital contributions from the venture members, of which the Company contributed approximately $18.0 million.

David Cramer, President and Chief Executive Officer, commented, “We are focused on the internalization of the PRO structure that we announced in early June and closed on July 1st. We’ve made significant progress on our strategic initiatives over the past few quarters, including the sale of non-core assets, repayment of floating rate debt, formation of two new joint ventures, repurchase of common shares, and now the internalization of the PRO structure, all of which position NSA for growth going forward. I'd like to acknowledge and thank our PROs and the NSA team members for the significant time and effort that they have devoted to these initiatives as well as our People, Process and Platform projects, which we expect will significantly benefit our results going forward.”

Mr. Cramer further commented, “We continue to feel pressure on operating results in this very competitive environment due to factors including less demand as a result of a muted housing market and the absorption of new supply, which is felt most prominently in the Sunbelt markets. We believe that these pressures will remain throughout the back half of the year. We also acknowledge that the transition of the PRO-managed stores creates an additional lift for our team in the near-term. We are acutely focused on navigating today’s challenges and remain well-positioned to benefit when sector headwinds subside.”

Net income decreased $13.2 million for the second quarter of 2024 and increased $41.5 million for the six months ended June 30, 2024 ("year-to-date") as compared to the same periods in 2023. The decrease in net income in the second 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 six months ended June 30, 2024, partially offset by decreases in depreciation expense of $10.0 million and interest expense of $2.5 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 six months ended June 30, 2024.

The decreases in FFO and Core FFO for the second quarter of 2024 and year-to-date were the result of a decrease in NOI of 14.1% and 11.3%, respectively, which were partially offset by a decrease in interest expense of 6.2% and 3.0%, respectively, as compared to the same periods in 2023. The decrease in FFO and Core FFO per share and unit for the second quarter of 2024 and year-to-date was largely driven by a decrease in same store NOI and an increase in general and administrative expenses.

Year-over-year same store total revenues decreased 2.8% for the second quarter of 2024 and 2.2% year-to-date as compared to the same period in 2023. The decrease for the second quarter was driven primarily by a 320 basis point decrease in average occupancy, partially offset by a 0.6% increase in average annualized rental revenue per occupied square foot. The year-to-date same store total revenue decrease was driven primarily by a 350 basis point decrease in average occupancy, partially offset by a 1.5% increase in average annualized rental revenue per occupied square foot. Markets which generated above portfolio average same store total revenue growth for the second quarter of 2024 include: San Juan, Wichita and New Orleans. Markets which generated below portfolio average same store total revenue growth for the second quarter of 2024 include: Atlanta, Phoenix and Sarasota-Bradenton.

Year-over-year same store property operating expenses increased 4.8% for the second quarter of 2024 and 4.6% year-to-date as compared to the same periods in 2023. The increases primarily resulted from increases in marketing and insurance expense.

Disposition and Investment Activity

During the second quarter, NSA invested $25.2 million in the acquisition of three self storage properties completed under a 1031 exchange, consisting of approximately 200,000 rentable square feet configured in approximately 1,300 storage units. Total consideration for these acquisitions included approximately $25.1 million of net cash and the assumption of approximately $0.1 million of other liabilities.

During the second quarter, NSA sold one self storage property, consisting of approximately 155,000 rentable square feet configured in approximately 1,000 storage units for approximately $8.0 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. On June 28, 2024, NSA repurchased 194,888 subordinated performance units for approximately $8.5 million in cash in connection with the PRO structure internalization.

Balance Sheet

During the second quarter, NSA repurchased 1,908,397 of the Company's common shares for approximately $71.6 million under the previously approved share repurchase program.

Common Share Dividends

On May 16, 2024, NSA's Board of Trustees declared a quarterly cash dividend of $0.56 per common share. The second quarter 2024 dividend was paid on June 28, 2024 to shareholders of record as of June 14, 2024.

2024 Guidance

The following table outlines NSA's updated and prior Core FFO guidance estimates and related assumptions for the year ended December 31, 2024. The Company's revisions to Core FFO guidance estimates are primarily driven by lower same store growth assumptions. Certain line items in the table below have been adjusted for the impact of the internalization of the PRO structure, such as general and administrative expenses, management fees and other revenue, and subordinated performance unit distributions. Additionally, the Core FFO per share guidance incorporates an estimated weighted average share count of approximately 135.0 million beginning July 1, 2024, or approximately 126.6 million for the full year 2024.

(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. Subordinated performance units, DownREIT subordinated performance units and 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). 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. For additional information about the conversion of subordinated performance units and DownREIT subordinated performance units into OP units, see Note 10 to the Company's most recent Annual Report on Form 10-K, filed with the Securities and Exchange Commission. 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).

(5)			We have reflected 4,608,445 Series B Preferred Shares herein, which corresponds to the $115.2 million liquidation preference reflected on the balance sheet at June 30, 2024, although the Company’s balance sheet describes 5,668,128 Series B Preferred Shares issued and outstanding at June 30, 2024. As part of a March 16, 2023 property acquisition of 15 properties from an affiliate of Personal Mini, the Company recorded a $26.1 million promissory note receivable from the Personal Mini affiliate, and the affiliate of Personal Mini used the loan proceeds to acquire $26.1 million of subordinated performance units. 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.
(6)			The July 1, 2024 balance reflects the conversion of all subordinated performance units (including each DownREIT subordinated performance unit) into OP units effective July 1, 2024, in connection with the internalization of the PRO structure, at a weighted average conversion ratio of approximately 1.51. The conversion ratios were calculated by dividing the average cash available for distribution (CAD) per subordinated performance unit by 110% of the CAD per OP unit over a one-year period ending December 31, 2023. The July 1, 2024 balance also includes 775,210 OP units issued in connection with the purchase of the PRO management contracts and specified intellectual property, and 773,656 OP units issued in connection with the purchase of rights to the PRO tenant insurance business. These newly issued OP units, as well as OP units issued upon conversion of SP units, will generally have a one-year lockup on resales.
(7)			Balances exclude 208,400 long-term incentive plan ("LTIP") units which only vest and participate in dividend distributions upon the future contribution of properties from the PROs.

(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 $3.4 million of fair value of debt adjustments and $12.2 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", are NSA's experienced regional self storage operators with local operational focus and expertise. As of June 30, 2024, the Company had eight PROs: Optivest Properties, Guardian Storage Centers, Storage Solutions, Hide-Away, Personal Mini, Southern Self Storage, Moove In Self Storage and Blue Sky Self Storage. Effective July 1, 2024, NSA completed the internalization of its PRO structure. NSA plans to transition the majority of operations in a phased approach, which is expected to occur 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, are Class B common units of limited partner interest in the Company's operating partnership. SP units, which are linked to the performance of specific contributed portfolios, are intended to incentivize the Company's PROs to drive operating performance and support the sustainability of the operating cash flow generated by the contributed self storage properties that the PROs continue to manage on NSA's behalf. Because subordinated performance unit holders receive distributions only after portfolio-specific minimum performance thresholds are satisfied, the Company believes SP units play a key role in aligning the interests of the Company's PROs with NSA and the Company's shareholders. The DownREIT partnerships also issue units of limited partner interest that are 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 converted into 17,984,787 OP units and DownREIT OP units.
