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 located within the top 100 metropolitan statistical areas throughout the United States.

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 National Storage Affiliates Trust 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, 2021, the Company's operating partnership was the primary beneficiary of, and therefore consolidated, 22 partnerships that are considered VIEs, which owned 48 self storage properties. As of December 31, 2020, the Company's operating partnership was the primary beneficiary of, and therefore consolidated, 21 partnerships that are considered VIEs, which owned 34 self storage properties. The net book value of the real estate owned by these VIEs was $434.0 million and $225.1 million as of June 30, 2021 and December 31, 2020, 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 $100.7 million and $100.7 million as of June 30, 2021 and December 31, 2020, respectively. The creditors of the consolidated VIEs do not have recourse to the Company's general credit.

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 and certain of the Company’s PROs have 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, 2021 and 2020, the Company recognized $3.6 million and $2.7 million, respectively, of tenant insurance and tenant warranty protection plan revenues and during the six months ended June 30, 2021 and 2020, the Company recognized $6.7 million and $5.3 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, 2021 and 2020, the Company recognized retail sales of $0.7 million and $0.4 million, respectively, and during the six months ended June 30, 2021 and 2020, the Company recognized retail sales of $1.2 million and $0.8 million, respectively.

Management fees and other revenue

Management fees and other revenue consist of property management fees, platform fees, call center fees, acquisition fees, and a portion of tenant warranty protection or tenant insurance proceeds that the Company earns for managing and operating its unconsolidated real estate ventures.

With respect to both the 2018 Joint Venture and the 2016 Joint Venture (as each is 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 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. With respect to the 2016 Joint Venture only, the call center fees are equal to 1% of each of monthly gross revenues and net sales revenues from the 2016 Joint Venture properties. During the three months ended June 30, 2021 and 2020, the Company recognized property management fees, call center fees and platform fees of $3.6 million and $3.2 million, respectively, and during the six months ended June 30, 2021 and 2020, the Company recognized property management fees, call center fees and platform fees of $7.1 million and $6.4 million, respectively.

For acquisition fees, the Company provides sourcing, underwriting and administration services to the unconsolidated real estate ventures. The 2016 Joint Venture paid the Company a $4.1 million acquisition fee equal to 0.65% of the gross capitalization (including debt and equity) of the original 66-property 2016 Joint Venture portfolio (the "Initial 2016 JV Portfolio") in 2016, at the time of the Initial 2016 JV Portfolio acquisition. The 2018 Joint Venture paid the Company a $4.0 million acquisition fee related to the initial acquisition of properties by the 2018 Joint Venture (the "Initial 2018 JV Portfolio") in 2018, at the time of the Initial 2018 JV Portfolio acquisition. These fees are refundable to the unconsolidated real estate ventures, on a prorated basis, if the Company is removed as the managing member during the initial four year life of the unconsolidated real estate ventures and as such, the Company's performance obligation for these acquisition fees are satisfied over a four year period. Accordingly, the Company's performance obligation related to the Initial 2016 JV Portfolio was satisfied during the year ended December 31, 2020. As of June 30, 2021 and December 31, 2020, the Company had deferred revenue related to the acquisition fees of $0.9 million and $1.3 million, respectively.

The Company also earns acquisition fees for properties acquired by the unconsolidated real estate ventures subsequent to the Initial 2016 JV Portfolio and the Initial 2018 JV Portfolio. These fees are based on a percentage of the gross capitalization of the acquired assets determined by the members of the 2016 Joint Venture and the 2018 Joint Venture, and are generally earned when the unconsolidated real estate ventures obtain title and control of an acquired property. During the three months ended June 30, 2021 and 2020, the Company recognized acquisition fees of $0.2 million and $0.4 million, respectively, and during the six months ended June 30, 2021 and 2020, the Company recognized acquisition fees of $0.4 million and $0.9 million, respectively.

An affiliate of the Company facilitates tenant warranty protection or tenant insurance programs for tenants of the properties in the unconsolidated real estate ventures in exchange for 50% of all proceeds from such programs at each unconsolidated real estate venture property. During the three months ended June 30, 2021 and 2020, the Company recognized $2.2 million and $1.9 million, respectively, of revenue related to these activities and during the six months ended June 30, 2021 and 2020, the Company recognized $4.1 million and $3.5 million, respectively, of revenue related to these activities.

Gain on sale of self storage properties

The Company recognizes gains from disposition of facilities 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. 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 the 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 operating partnership or its subsidiaries. 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 interest is adjusted is reflected as an adjustment to additional paid-in capital on the condensed consolidated balance sheets.

Allocation of Net Income (Loss)

The distribution rights and priorities set forth in the operating partnership's LP Agreement differ from what is reflected by the underlying percentage ownership interests of the unitholders. Accordingly, the Company allocates GAAP income (loss) utilizing the hypothetical liquidation at book value ("HLBV") method, in which the Company allocates income or loss 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. The HLBV method is commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder’s ownership percentage.

The HLBV method is a balance sheet-focused approach to income (loss) allocation. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if the operating partnership were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership, and net income (loss) attributable to National Storage Affiliates Trust could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in net income (or net loss) attributable to National Storage Affiliates Trust during a period when the Company reports consolidated net loss (or net income), or net income (or net loss) attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income (or net loss). The computations of basic and diluted earnings (loss) per share may be materially affected by these disproportionate income (loss) allocations, resulting in volatile fluctuations of basic and diluted earnings (loss) per share.

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. Under the HLBV method of allocating income (loss) discussed above, a calculation is prepared at each balance sheet date by applying the HLBV method including, and excluding, the assets and liabilities resulting from the Company's cash flow hedge derivative instruments to determine comprehensive income (loss) attributable to National Storage Affiliates Trust. As a result of the distribution rights and priorities set forth in the operating partnership's LP Agreement, in any given period, other comprehensive income (loss) may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership and as compared to their respective allocation of net income (loss).

Restricted Cash

The Company's restricted cash consists of escrowed funds deposited with financial institutions 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

Forward Equity Offering

On September 22, 2020, the Company entered into an underwriting agreement, as well as certain forward sale agreements, with a syndicate of banks acting as underwriters, forward sellers, and/or forward purchasers in connection with an underwritten public offering of 4,500,000 common shares of beneficial interest, $0.01 par value per share of the Company ("common shares") at a public offering price of $33.15 per share (the "forward offering"). The underwriters were granted a 30-day option to purchase up to an additional 675,000 common shares at the same price, which they partially exercised for an additional 400,000 common shares on October 6, 2020. Therefore, the forward sellers or their affiliates, at the Company's request, borrowed from third parties and sold to the underwriters an aggregate of 4,900,000 common shares, which the underwriters sold at an offering price of $33.15 per share, for proceeds of approximately $162.4 million. As a result of this forward construct, the Company did not receive any proceeds from the sale of such shares at closing. The Company has determined that the forward sale agreements are not considered to be derivative instruments under the guidance within ASC 815.

On December 30, 2020, the Company settled a portion of the forward offering by physically delivering 1,850,510 common shares to the forward purchasers for net proceeds of approximately $60.0 million. On March 22, 2021, the Company settled the remaining portion of the forward offering by physically delivering 3,049,490 common shares to the forward purchasers for net proceeds of approximately $97.3 million.

Common Share Offering

As discussed in Note 13, on July 23, 2021, the Company closed a follow-on public offering of 10,120,000 of its common shares, which included 1,320,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at a public offering price of $51.25 per share. The Company received aggregate net proceeds from the offering of approximately $497.4 million after deducting the underwriting discount and additional expenses associated with the offering.

At the Market ("ATM") Program

On February 27, 2019, the Company entered into a sales agreement with certain sales agents, pursuant to which the Company may sell from time to time up to an aggregate of $250.0 million common shares and 6.000% Series A cumulative redeemable preferred shares of beneficial interest ("Series A preferred 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. Forward sale agreements, if any, will include only the Company's common shares and will not include any Series A preferred shares. 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 and Series A preferred 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.

Under the sales agreement, the Company offered and sold shares having an aggregate gross sales price of approximately $219.0 million from February 27, 2019 through May 19, 2021, leaving offered shares having an aggregate gross sales price of up to approximately $31.0 million available for offer and sale under the sales agreement (the "remaining available offered shares"). On May 19, 2021, the Company entered into an amendment to the sales agreement with certain sales agents, whereby the Company increased the aggregate gross sale price under the program to $400.0 million, which includes the remaining available offered shares.

During the three months ended June 30, 2021, the Company sold 2,390,000 common shares through the ATM program at an average offering price of $43.86 per share, resulting in net proceeds to the Company of approximately $103.7 million, after deducting compensation payable by the Company to such agents and offering expenses. During the six months ended June 30, 2021, the Company sold 3,032,726 common shares through the ATM program at an average offering price of $42.92 per share, resulting in net proceeds to the Company of approximately $129.1 million, after deducting compensation payable by the Company to such agents and offering expenses.

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 OP units and subordinated performance units, at such prices and on such other terms as it determines in its sole discretion.

As of June 30, 2021 and December 31, 2020, units reflecting noncontrolling interests consisted of the following:


	June 30, 2021	December 31, 2020
Series A-1 preferred units	633,382	637,382
OP units	30,069,539	29,616,809
Subordinated performance units	9,510,894	9,030,872
LTIP units	778,362	734,196
DownREIT units
DownREIT OP units	1,924,918	1,924,918
DownREIT subordinated performance units	4,337,111	4,337,111
Total	47,254,206	46,281,288

Series A-1 Preferred Units

The 6.000% Series A-1 Cumulative Redeemable Preferred Units ("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 Series A preferred shares on a one-for-one basis, subject to adjustments. The Series A preferred shares are redeemable by the Company for a cash redemption price of $25.00 per share, plus accrued but unpaid dividends. The decrease in Series A-1 preferred units outstanding from December 31, 2020 to June 30, 2021 was due to the redemption of 4,000 Series A-1 preferred units for an equal 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 the Company's 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.

The increase in OP units outstanding from December 31, 2020 to June 30, 2021 was due to the issuance of 559,463 OP units in connection with the acquisition of self storage properties, 142,405 LTIP units which were converted into an equivalent number of OP units and 63,033 OP units issued upon the conversion of 32,741 subordinated performance units (as discussed further below) partially offset by the redemption of 312,171 OP units for an equal number of common shares.

Subordinated Performance Units and DownREIT Subordinated Performance Units

Following such lock-out period, a holder of subordinated performance units in the Company's operating partnership may elect a voluntary conversion one time each year on or prior to December 1st to convert a pre-determined portion of such subordinated performance units into OP units in the Company's operating partnership, with such conversion effective January 1st of the following year, with each subordinated performance unit being converted into the number of OP units determined by dividing the average cash available for distribution, or CAD, per unit on the series of specific subordinated performance units over the one-year period prior to conversion by 110% of the CAD per unit on the OP units determined over the same period. CAD per unit on the series of specific subordinated performance units and OP units is determined by the Company based generally upon the application of the provisions of the LP Agreement applicable to the distributions of operating cash flow and capital transactions proceeds.

The increase in subordinated performance units outstanding from December 31, 2020 to June 30, 2021 was due to the issuance of 512,763 subordinated performance units for co-investment by the Company's PROs in connection with the acquisition of self storage properties partially offset by the voluntary conversion of 32,741 subordinated performance units into 63,033 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, 2020 to June 30, 2021 was due to the issuance of 186,571 compensatory LTIP units to employees and trustees, net of forfeitures, partially offset by the conversion of 142,405 LTIP units into an equivalent number of OP units.

(1)Represents the effective interest rate as of June 30, 2021. Effective interest rate incorporates the stated rate plus the impact of interest rate cash flow hedges and discount and premium amortization, if applicable. For the revolving line of credit, the effective interest rate excludes fees for unused borrowings.

As of June 30, 2021, the Company's unsecured credit facility provided for total borrowings of $1.275 billion (the "credit facility"). The credit facility consists of the following components: (i) a revolving line of credit (the "Revolver") which provides for a total borrowing commitment up to $500.0 million, under which the Company may borrow, repay and re-borrow amounts, (ii) a $125.0 million tranche A term loan facility (the "Term Loan A"), (iii) a $250.0 million tranche B term loan facility (the "Term Loan B"), (iv) a $225.0 million tranche C term loan facility (the "Term Loan C"), and (v) a $175.0 million tranche D term loan facility (the "Term Loan D"). As of June 30, 2021, the Company had an expansion option under the credit facility, which, if exercised in full, would provide for a total credit facility of $1.750 billion.

As of June 30, 2021, the Company had outstanding letters of credit totaling $5.7 million and would have had the capacity to borrow remaining Revolver commitments of $228.8 million while remaining in compliance with the credit facility's financial covenants. At June 30, 2021, the Company was in compliance with all such covenants.

As discussed in Note 13, in July 2021, the Company received commitments from a syndicated group of lenders to partially exercise the expansion option under its unsecured credit facility for a $100.0 million tranche E term loan facility.

2026, May 2031 and 2033 Senior Unsecured Notes

On May 3, 2021, the operating partnership as issuer, and the Company, entered into a Note Purchase Agreement (the "Note Purchase Agreement") which provides for the private placement of $35.0 million of 2.16% senior unsecured notes due May 4, 2026 (the "2026 Notes"), $90.0 million of 3.00% senior unsecured notes due May 4, 2031 (the "May 2031 Notes") and $55.0 million of 3.10% senior unsecured notes due May 4, 2033 (the "2033 Notes" and together with the 2026 Notes and May 2031 Notes the "Senior Unsecured Notes") to certain institutional investors. The Senior Unsecured Notes are governed by the Note Purchase Agreement and on May 26, 2021 the operating partnership issued the 2033 Notes. As discussed in Note 13, on July 26, 2021 the operating partnership issued the 2026 Notes and the May 2031 Notes.

Interest is paid semiannually, on May 31st and November 30th of each year, commencing on November 30, 2021. The Senior Unsecured Notes are senior unsecured obligations of the Company and are jointly and severally guaranteed by certain of the Company's subsidiaries, as subsidiary guarantors. The Senior Unsecured Notes rank pari passu with the credit facility, 2023 Term Loan Facility, 2028 Term Loan Facility, 2029 Term Loan Facility, 2029 Senior Unsecured Notes, 2030 Senior Unsecured Notes, August 2031 Senior Unsecured Notes and 2032 Senior Unsecured Notes. The Note Purchase Agreement contains financial covenants that are substantially similar to those of the Company's credit facility. In addition, the terms of the Note Purchase Agreement contain customary affirmative and negative covenants that, among other things, limit the Company's ability to make distributions or certain investments, incur debt, incur liens and enter into certain transactions.

Fixed Rate Mortgage Payable

As discussed in Note 13, on July 9, 2021, the Company entered into an agreement with a single lender for an $88.0 million debt financing secured by a first lien on eight of the Company's self storage properties. This interest-only loan matures in July 2028 and has a fixed interest rate of 2.77%.

Future Debt Obligations

Based on existing debt agreements in effect as of June 30, 2021, the scheduled principal and maturity payments for the Company's outstanding borrowings are presented in the table below (in thousands):

Earnings (loss) per share - diluted	$	0.25	$	0.10	$	0.44	$	0.16

As discussed in Note 2, the Company allocates GAAP income (loss) utilizing the HLBV method, in which the Company allocates income or loss 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. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to National Storage Affiliates Trust and noncontrolling interests, resulting in volatile fluctuations of basic and diluted earnings (loss) per share.

Outstanding equity interests of the Company's operating partnership and DownREIT partnerships are considered potential common shares for purposes of calculating diluted earnings (loss) 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, 2021, 445,618 unvested LTIP units that vest based on a service or market condition are excluded from the calculation of diluted earnings (loss) per share as they are not dilutive to earnings (loss) per share. In addition, certain LTIP units vest upon the future acquisition of properties sourced by PROs or the completion of expansion projects. For the three and six months ended June 30, 2021, 252,894 unvested LTIP units that vest upon the future acquisition of properties, or the completion of expansion projects, are excluded from the calculation of diluted earnings (loss) per share because the contingency for the units to vest has not been attained as of the end of the reported periods.

Subordinated performance units may also, under certain circumstances, be convertible into OP units which are exchangeable for common shares as described above, and DownREIT subordinated performance units may, under certain circumstances, be exchangeable for subordinated performance units on a one-for-one basis. Subordinated performance units are only convertible into OP units, after a two year lock-out period and then generally (i) at the holder’s election only upon the achievement of certain performance thresholds relating to the properties to which such subordinated performance units relate or (ii) at the Company's election upon a retirement event of a PRO that holds such subordinated performance units or upon certain qualifying terminations. Although subordinated performance units may only be convertible after a two year lock-out period, the Company assumes a hypothetical conversion of each subordinated performance unit (including each DownREIT subordinated performance unit) into OP units (with subsequently assumed redemption into common shares) for the purposes of calculating diluted weighted average common shares. This hypothetical conversion is calculated using historical financial information, and as a result, is not necessarily indicative of the results of operations, cash flows or financial position of the Company upon expiration of the two-year lock out period on conversions.

For the three and six months ended June 30, 2020, potential common shares totaling 46.9 million and 49.0 million, respectively, related to OP units, DownREIT OP units, subordinated performance units, DownREIT subordinated performance units and vested LTIP units have been excluded from the calculation of diluted earnings (loss) per share as they are not dilutive to earnings (loss) 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

Supervisory and Administrative Fees

For the self storage properties that are managed by the PROs, the Company has entered into asset management agreements with the PROs to provide leasing, operating, supervisory and administrative services. The asset management agreements generally provide for fees ranging from 5% to 6% of gross revenue for the managed self storage properties. During the three months ended June 30, 2021 and 2020, the Company incurred $4.9 million and $3.5 million, respectively, for supervisory and administrative fees to the PROs and during the six months ended June 30, 2021 and 2020, the Company incurred $9.1 million and $8.8 million, respectively, for supervisory and administrative fees to the PROs. Such fees are included in general and administrative expenses in the accompanying condensed consolidated statements of operations.

Payroll Services

For the self storage properties that are managed by the PROs, the employees responsible for operations are employees of the PROs who charge the Company for the costs associated with the respective employees. For the three months ended June 30, 2021 and 2020, the Company incurred $6.6 million and $5.5 million, respectively, for payroll and related costs reimbursable to these PROs and for the six months ended June 30, 2021 and 2020, the Company incurred $13.0 million and $14.3 million, respectively, for payroll and related costs reimbursable to these PROs. Such costs are included in property operating expenses in the accompanying condensed consolidated statements of operations.

Due Diligence Costs

During the three months ended June 30, 2021 and 2020, the Company incurred $0.2 million and $0.1 million of expenses payable to certain PROs related to self storage property acquisitions sourced by the PROs and during the six months ended June 30, 2021 and 2020, the Company incurred $0.5 million and $0.2 million, respectively, of expenses payable to certain PROs related to self storage property acquisitions sourced by the PROs. These expenses, which are based on the volume of transactions sourced by the PROs, are intended to reimburse the PROs for due diligence costs incurred in the sourcing and underwriting process. These due diligence costs are capitalized as part of the basis of the acquired self storage properties.

Self Storage Property Acquisitions

During the year ended December 31, 2020, the Company acquired one self storage property from a company in which an entity controlled by J. Timothy Warren, a trustee of the Company, was an investor. Mr. Warren's adult children held an ownership interest in such investor entity. The total consideration payable by the Company for this property was subject to an earnout payable in three tranches based on the performance of the property over six, 12 and 18 month periods. During the six months ended June 30, 2021, in connection with the 12 month tranche of the earnout, the Company paid aggregate consideration totaling approximately $2.0 million, and the interest of Mr. Warren's children was 13,105 OP Units with a value of approximately $0.6 million.

During the six months ended June 30, 2021, the Company acquired one self storage property for $8.8 million from a company in which an entity controlled by J. Timothy Warren, a trustee of the Company, was an investor. Mr. Warren's adult children held an ownership interest in such investor entity. Of the total consideration paid, the interest of Mr. Warren's children was approximately 29,123 OP Units with a value of $1.1 million.

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 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 at December 31, 2019	$	(18,963)

Swap ineffectiveness	34
Losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive loss	4,546
Unrealized losses on interest rate swaps included in accumulated other comprehensive (loss) income	(76,792)
Fair value at June 30, 2020	$	(91,175)

Fair value at December 31, 2020	$	(77,918)


Swap ineffectiveness	24
Losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive loss	10,081
Unrealized gains on interest rate swaps included in accumulated other comprehensive (loss) income	14,175
Fair value at June 30, 2021	$	(53,638)

As of June 30, 2021 and December 31, 2020, the Company had outstanding interest rate swaps with aggregate notional amounts of $1,125.0 million and $1,125.0 million, respectively, designated as cash flow hedges. As of June 30, 2021, the Company's swaps had a weighted average remaining term of approximately 3.3 years. The fair value of these swaps are presented as interest rate swap liabilities in the Company's 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, 2021 remain constant, the Company estimates that during the next 12 months, the Company would reclassify into earnings approximately $20.2 million of the unrealized losses included in accumulated other comprehensive income (loss). If market interest rates increase above the 1.92% weighted average fixed rate under these interest rate swaps, the Company will benefit from net cash payments due 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, 2021 and 2020. For financial assets and liabilities that utilize Level 2 inputs, the Company utilizes both direct and indirect observable price quotes, including LIBOR yield curves. The Company uses valuation techniques for Level 2 financial assets and liabilities which include LIBOR 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, 2021, 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, and accounts payable and accrued liabilities reflected in the balance sheets at June 30, 2021 and December 31, 2020, approximate fair value due to the short term nature of these financial assets and liabilities. The carrying value of variable rate debt financing reflected in the balance sheets at June 30, 2021 and December 31, 2020 approximates fair value as the changes in their associated interest rates reflect the current market and credit risk is similar to when the loans were originally obtained.

The combined principal balance of the Company's fixed rate mortgages payable was approximately $218.0 million as of June 30, 2021 with a fair value of approximately $239.5 million (categorized within Level 2 of the fair value hierarchy). In determining the fair value, the Company estimated a weighted average market interest rate of approximately 2.23%, compared to the weighted average contractual interest rate of 4.67%. The combined principal

balance of the Company's fixed rate mortgages was approximately $223.6 million as of December 31, 2020 with a fair value of approximately $249.7 million. In determining the fair value as of December 31, 2020, the Company estimated a weighted average market interest rate of approximately 2.12%, compared to the weighted average contractual interest rate of 4.69%.

13. SUBSEQUENT EVENTS

Self Storage Property Acquisitions

Subsequent to June 30, 2021, the Company acquired seven self storage properties for approximately $68.6 million. Consideration for these acquisitions included approximately $57.1 million of net cash, the assumption of approximately $0.2 million of other working capital liabilities and OP equity of approximately $11.3 million (consisting of the issuance of 189,322 OP units and 10,870 subordinated performance units). Of these acquisitions, one self storage property for $11.7 million was acquired from a company in which an entity controlled by J. Timothy Warren, a trustee of the Company, was an investor. Mr. Warren's adult children held an ownership interest in such investor entity. Of the total consideration paid, the interest of Mr. Warren's children was approximately 9,290 OP Units with a value of $0.5 million.

Common Share Offering

On July 23, 2021, the Company closed a follow-on public offering of 10,120,000 of its common shares, which included 1,320,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at a public offering price of $51.25 per share. The Company received aggregate net proceeds from the offering of approximately $497.4 million after deducting the underwriting discount and additional expenses associated with the offering. The Company used the net proceeds for self storage property acquisitions, general corporate purposes and to repay borrowings outstanding under its Revolver.

ATM Program

Subsequent to June 30, 2021, the Company sold 782,000 of its common shares through the ATM program at an average offering price of $51.82 per share, resulting in net proceeds to the Company of approximately $40.0 million, after deducting compensation payable by the Company to such agents and offering expenses. The Company used the net proceeds for self storage property acquisitions and to repay borrowings outstanding under its Revolver.

2026 and May 2031 Senior Unsecured Notes

On July 26, 2021 the operating partnership issued the 2026 Notes and the May 2031 Notes. See Note 8 for additional detail regarding the 2026 Notes and the May 2031 Notes. The Company used the proceeds to repay outstanding amounts on its revolving line of credit and for general corporate purposes.

Fixed Rate Mortgage Payable

On July 9, 2021, the Company entered into an agreement with a single lender for an $88.0 million debt financing secured by a first lien on eight of the Company's self storage properties. This interest-only loan matures in July 2028 and has a fixed interest rate of 2.77%. The Company used the net proceeds to repay borrowings outstanding under its Revolver.

Term Loan Commitment

The Company received commitments in July 2021 from a syndicated group of lenders to partially exercise the expansion option under its unsecured credit facility for a $100.0 million tranche E term loan facility (the "Term Loan E"). The Term Loan E is expected to close during the third quarter of 2021 and mature in early 2027. The credit facility's existing financial covenants are not expected to change as a result of the expansion. The Company plans to use the proceeds from the Term Loan E for self storage property acquisitions and for general corporate purposes.

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

We make forward-looking statements in this report that are subject to risks and uncertainties. These forward-looking statements include information about possible or assumed future results of our business, financial condition, liquidity, results of operations, plans and objectives. When we use the words "believe," "expect," "anticipate," "estimate," "plan," "continue," "intend," "should," "may," or similar expressions, we intend to identify forward-looking statements.

The forward-looking statements contained in this report reflect our current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions, and changes in circumstances that may cause our actual results to differ significantly from those expressed in any forward-looking statement. One of the most significant factors is the ongoing and potential impact of the current outbreak of the COVID-19 pandemic on the economy, the self storage industry and the broader financial markets, which may have a significant negative impact on the Company's financial condition, results of operations and cash flows. The Company is unable to predict whether the continuing effects of the COVID-19 pandemic will trigger a further economic slowdown or a recession and to what extent the Company will experience disruptions related to the COVID-19 pandemic for the remainder of 2021 or thereafter. In particular, it is difficult to fully assess the impact of COVID-19 at this time due to, among other factors, uncertainty regarding the severity and duration of the outbreak domestically and internationally, uncertainty regarding the effectiveness of federal, state and local governments' efforts to contain the spread of COVID-19 and respond to its direct and indirect impact on the U.S. economy and economic activity, including the timing of the successful distribution of an effective vaccine, the rate and level of persons receiving vaccinations and the efficacy of such vaccines. The current COVID-19 pandemic has impacted, and is likely to continue to impact, directly or indirectly, many of the other important factors below and the risks described in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC (the "Annual Report"), and the Company's subsequent filings under the Exchange Act.

Statements regarding the following subjects, among others, may be forward-looking:

•market trends in our industry, interest rates, the debt and lending markets or the general economy;

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 within the top 100 metropolitan statistical areas throughout the United States.

Our executive chairman of the board of trustees and former 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. We believe that his vision, which is the foundation of the Company, aligns the interests of our participating regional operators ("PROs"), with those of our

public shareholders by allowing our PROs to participate alongside our shareholders in our financial performance and the performance of our PROs' managed portfolios. This structure offers our 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.

Our Structure

Our structure promotes operator accountability as subordinated performance units issued to our PROs in exchange for the contribution of their properties are entitled to distributions only after those properties satisfy minimum performance thresholds. In the event of a material reduction in operating cash flow, distributions on our subordinated performance units will be reduced before or disproportionately to distributions on our common shares held by our common shareholders. In addition, we expect our PROs will generally co-invest subordinated equity in the form of subordinated performance units in each acquisition that they source, and the value of these subordinated performance units will fluctuate with the performance of their managed portfolios. Therefore, our PROs are incentivized to select acquisitions that are expected to exceed minimum performance thresholds, thereby increasing the value of their subordinated equity stake. We expect that our shareholders will benefit from the higher levels of property performance that our PROs are incentivized to deliver.

Our Property Management Platform

Through our property management platform, we direct, manage and control the day-to-day operations and affairs of certain consolidated properties and our unconsolidated real estate ventures. As of June 30, 2021, our property management platform managed and controlled 293 of our consolidated properties and 177 of our unconsolidated real estate venture properties.

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 PROs

The Company had ten PROs as of June 30, 2021: Northwest, Optivest, Guardian, Move It, Storage Solutions, Hide Away, Personal Mini, Southern, Moove In and Blue Sky. We seek to further expand our platform by continuing to recruit additional established self storage operators, while integrating our operations through the implementation of centralized initiatives, including management information systems, revenue enhancement, and cost optimization programs. Our national platform allows us to capture cost savings by eliminating redundancies and utilizing economies of scale across the property management platforms of our PROs while also providing greater access to lower-cost capital.

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 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. We have an attractive, high quality potential acquisition pipeline that we expect will continue to drive our future growth.

As of June 30, 2021, we owned a geographically diversified portfolio of 687 self storage properties, located in 33 states and Puerto Rico, comprising approximately 42.5 million rentable square feet, configured in approximately 334,000 storage units. Of these properties, 283 were acquired by us from our PROs, 403 were acquired from third-party sellers and one was acquired from the 2016 Joint Venture.

During the six months ended June 30, 2021, we acquired 43 self storage properties for $435.4 million, comprising approximately 3.2 million rentable square feet, configured in approximately 25,000 storage units. Of these acquisitions, seven were acquired from our PROs and 36 were acquired from third-party sellers.

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 177 properties, to present a potential acquisition opportunity. This 75% third-party share of gross real estate assets is approximately $1.5 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.

2018 Joint Venture

As of June 30, 2021, our 2018 Joint Venture, in which we have a 25% interest, owned and operated a portfolio of 103 properties containing approximately 7.8 million rentable square feet, configured in approximately 64,000 storage units and located across 17 states.

2016 Joint Venture

As of June 30, 2021, our 2016 Joint Venture, in which we have a 25% ownership interest, owned and operated a portfolio of 74 properties containing approximately 4.9 million rentable square feet, configured in approximately 40,000 storage units and located across 13 states.

COVID-19

We continue to closely monitor the impact of the COVID-19 pandemic on all aspects of our business. The outbreak of COVID-19 in many countries, including the United States, has adversely impacted economic activity. As cases of COVID-19 have increased, most states and municipalities have reacted by instituting, extending or reinstating quarantines, mandating business and school closures, requiring restrictions on travel, "shelter-in-place" and/or "stay-at-home" orders, and imposing restrictions on the types of businesses that may continue to operate. These containment measures generally do not apply to businesses, like ours, which are designated as "essential," but may apply to certain of our tenants, employees, vendors, lenders and joint venture partners.

As of the date of this report, our stores continue to operate and we are in compliance with federal, state and local COVID-19 guidelines and mandates. In response to the pandemic, we have continued to maintain increased levels and frequency of cleaning and sanitation of our self storage facilities and the recommended social distancing guidelines. Many of our stores feature online rental capabilities whereby a customer can complete the entire rental process online and receive an access code to the storage facility. For the remainder of our stores that do not yet benefit from the online rental feature, the combination of call center and email communication eliminates the need for any physical contact between customers and employees.

Due to the pandemic, we experienced a slowdown in overall business activity during the second quarter of 2020. However, we observed sustained improvement in our property operating results during the third and fourth quarters of 2020 and continuing through the second quarter of 2021.

Results of Operations

When reviewing our results of operations it is important to consider the timing of acquisition activity. We acquired 43 self storage properties during the six months ended June 30, 2021 and 77 self storage properties during the year ended December 31, 2020. 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.

To help analyze the operating performance of our self storage properties, we also discuss and analyze operating results relating to our same store portfolio. Our same store portfolio is defined as those properties owned and operated on a stabilized basis since the first day of the earliest year presented. We consider a property to be stabilized once it has achieved an occupancy rate that is representative of similar properties in the applicable market. We exclude 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. As of June 30, 2021, our same store portfolio consisted of 560 consolidated self storage properties.

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.

Three Months Ended June 30, 2021 compared to the Three Months Ended June 30, 2020

Net income was $35.7 million for the three months ended June 30, 2021, compared to $17.8 million for the three months ended June 30, 2020, an increase of $17.9 million. The increase was primarily due to an increase in net operating income ("NOI") generated from 80 self storage properties acquired between July 1, 2020 and June 30, 2021 and same store NOI growth, partially offset by increases in depreciation and amortization. For a description of NOI, see "Non-GAAP Financial Measures – NOI".

The following table illustrates the changes in rental revenue, other property-related revenue, management fees and other revenue, property operating expenses, and other expenses for the three months ended June 30, 2021 compared to the three months ended June 30, 2020 (dollars in thousands):

Total Revenue

Our total revenue increased by $33.8 million, or 32.4%, for the three months ended June 30, 2021, as compared to the three months ended June 30, 2020. This increase was primarily attributable to incremental revenue from 80 self storage properties acquired between July 1, 2020 and June 30, 2021 and an increase in total portfolio average occupancy from 87.5% for the three months ended June 30, 2020 to 94.8% for the three months ended June 30, 2021. 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 increased by $32.0 million, or 33.6%, for the three months ended June 30, 2021, as compared to the three months ended June 30, 2020. The increase in rental revenue was due to a $17.7 million increase in non-same store rental revenue which was primarily attributable to incremental rental revenue of $10.4 million from 60 self storage properties acquired between July 1, 2020 and March 31, 2021 and $5.2 million from 20 self storage properties acquired during the three months ended June 30, 2021. Same store portfolio rental revenues increased $14.3 million, or 16.0%, due to an increase in average occupancy from 87.8% for the three months ended June 30, 2020 to 95.4% for the three months ended June 30, 2021 and a 6.8% increase, from $11.97 to $12.78, in annualized same store rental revenue (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"), driven primarily by increased 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 $1.4 million, or 41.3%, for the three months ended June 30, 2021, as compared to the three months ended June 30, 2020. This increase primarily resulted from a $0.8 million increase in same store other property-related revenue and a $0.7 million increase in non-same store other property-related revenue which was primarily attributable to incremental other property-related revenue of $0.4 million from 60 self storage properties acquired between July 1, 2020 and March 31, 2021 and $0.2 million from 20 self storage properties acquired during the three months ended June 30, 2021.

Management Fees and Other Revenue

Management fees and other revenue, which are primarily related to managing and operating the unconsolidated real estate ventures, were $6.1 million for the three months ended June 30, 2021, compared to $5.7 million for the three months ended June 30, 2020, an increase of $0.4 million. This increase was primarily attributable to increases in tenant insurance fees and dividends.

Property Operating Expenses

Property operating expenses were $36.7 million for the three months ended June 30, 2021 compared to $30.3 million for the three months ended June 30, 2020, an increase of $6.4 million, or 21.1%. The increase in property operating expenses primarily resulted from a $5.2 million increase in non-same store property operating expenses that was primarily attributable to incremental property operating expenses of $3.8 million from 60 self storage properties acquired between July 1, 2020 and March 31, 2021 and $1.2 million from 20 self storage properties acquired during the three months ended June 30, 2021. Same store portfolio operating expenses increased $1.2 million, or 4.3%, due to increases in personnel expense, property taxes and repairs and maintenance expense offset by decreases in marketing expense.

General and Administrative Expenses

General and administrative expenses increased $2.1 million, or 20.5%, for the three months ended June 30, 2021, compared to the three months ended June 30, 2020. This increase was attributable to increases in supervisory and administrative fees charged by our PROs and personnel costs.

Depreciation and Amortization

Depreciation and amortization increased $6.7 million, or 23.0%, for the three months ended June 30, 2021, compared to the three months ended June 30, 2020. This increase was primarily attributable to incremental depreciation expense related to the 80 self storage properties acquired between July 1, 2020 and June 30, 2021, and an increase in amortization of customer in-place leases from $2.4 million for the three months ended June 30, 2020 to $4.0 million for the three months ended June 30, 2021.

Interest Expense

Interest expense increased $1.8 million, or 11.8%, for the three months ended June 30, 2021, compared to the three months ended June 30, 2020. The increase in interest expense was primarily attributable to additional borrowings in October 2020 consisting of the issuance of $150.0 million of 2.99% senior unsecured notes due August 5, 2030 and $100.0 million of 3.09% senior unsecured notes due August 5, 2032.

Equity In Earnings Of Unconsolidated Real Estate Ventures

Equity in earnings of unconsolidated real estate ventures represents our share of earnings and losses incurred through our 25% ownership interests in the 2018 Joint Venture and the 2016 Joint Venture. During the three months ended June 30, 2021, we recorded $1.2 million of equity in earnings from our unconsolidated real estate ventures compared to $0.1 million of earnings for the three months ended June 30, 2020.

Net Income Attributable to Noncontrolling Interests

As discussed in Note 2 in Item 1, we allocate GAAP income (loss) utilizing the HLBV method, in which we allocate income or loss based on the change in each unitholders' claim on the net assets of our operating partnership at period end after adjusting for any distributions or contributions made during such period.

Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to noncontrolling interests. Net income attributable to noncontrolling interests was $7.0 million for the three months ended June 30, 2021, compared to $7.4 million for the three months ended June 30, 2020.

Six Months Ended June 30, 2021 compared to the Six Months Ended June 30, 2020

Net income was $63.3 million for the six months ended June 30, 2021, compared to $33.6 million for the six months ended June 30, 2020, an increase of $29.7 million. The increase was primarily due to an increase in NOI generated from 80 self storage properties acquired between July 1, 2020 and June 30, 2021 and same store NOI growth, partially offset by increases in depreciation and amortization.

The following table illustrates the changes in rental revenue, other property-related revenue, management fees and other revenue, property operating expenses, and other expenses for the six months ended June 30, 2021 compared to the six months ended June 30, 2020 (dollars in thousands):

Depreciation and Amortization

Depreciation and amortization increased $10.1 million, or 17.2%, for the six months ended June 30, 2021, compared to the six months ended June 30, 2020. This increase was primarily attributable to incremental depreciation expense related to the 80 self storage properties acquired between July 1, 2020 and June 30, 2021, and an increase in amortization of customer in-place leases from $5.3 million for the six months ended June 30, 2020 to $6.4 million for the six months ended June 30, 2021.

Interest Expense

Interest expense increased $3.0 million, or 9.6%, for the six months ended June 30, 2021, compared to the six months ended June 30, 2020. The increase in interest expense was primarily attributable to higher outstanding borrowings including additional borrowings in October 2020 consisting of the issuance of $150.0 million of 2.99% senior unsecured notes due August 5, 2030 and $100.0 million of 3.09% senior unsecured notes due August 5, 2032.

Equity In Earnings (Losses) Of Unconsolidated Real Estate Ventures

Equity in earnings (losses) of unconsolidated real estate ventures represents our share of earnings and losses incurred through our 25% ownership interests in the 2018 Joint Venture and the 2016 Joint Venture. During the six months ended June 30, 2021, we recorded $1.9 million of equity in earnings from our unconsolidated real estate ventures compared to $0.3 million of losses for the six months ended June 30, 2020.

Net Income Attributable to Noncontrolling Interests

Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to noncontrolling interests. Net income attributable to noncontrolling interests was $13.8 million for the six months ended June 30, 2021, compared to $16.5 million for the six months ended June 30, 2020.

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, which we refer to as the White Paper, 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 items to record unconsolidated partnerships and joint ventures on the same basis. Distributions declared on subordinated performance units and DownREIT subordinated performance units represent 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 subordinated performance units, DownREIT subordinated performance units, preferred shares and preferred 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, organizational and offering costs, gains on debt forgiveness, gains (losses) on early extinguishment of debt, and after 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 consolidated financial statements.

The following table presents a reconciliation of net income (loss) to FFO and Core FFO for the three and six months ended June 30, 2021 and 2020 (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) 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 our 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(1) in 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.

(3) Represents the dilutive effect of the forward offering from the application of the treasury stock method.

The following table presents a reconciliation of earnings (loss) per share - diluted to FFO and Core FFO per share and unit for the three and six months ended June 30, 2021 and 2020:



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

(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 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, DownREIT subordinated performance units and LTIP units into OP units, see Note 9 in Item 1. 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 footnote(1).

NOI

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 and our PROs 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).

The following table presents a reconciliation of net income (loss) to NOI for the three and six months ended June 30, 2021 and 2020 (dollars in thousands):


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

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 our 2018 Joint Venture and 2016 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, organizational and offering expenses, equity-based compensation expense, losses on sale of properties and impairment of long-lived assets, minus gains on sale of properties and debt forgiveness, and after adjustments for unconsolidated partnerships and joint ventures. 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 (loss) to EBITDA and Adjusted EBITDA for the three and six months ended June 30, 2021 and 2020 (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 equity and debt offerings, and debt financings including borrowings under the credit facility, 2023 Term Loan Facility, 2028 Term Loan Facility and 2029 Term Loan 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, subordinated performance units, DownREIT OP units and DownREIT subordinated performance 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, OP units and subordinated performance 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. Currently, interest rates are low compared to historical levels. 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, including, but not limited to, the effects of the COVID-19 pandemic. 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, 2021, we had $22.4 million in cash and cash equivalents and $3.6 million of restricted cash, an increase in cash and cash equivalents of $3.7 million and an increase in restricted cash of $0.6 million from December 31, 2020. Restricted cash primarily consists of escrowed funds deposited with financial institutions 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 $144.3 million for the six months ended June 30, 2021 compared to $105.7 million for the six months ended June 30, 2020, an increase of $38.6 million. Our operating cash flow increased primarily due to the 37 self storage properties acquired between July 1, 2020 and December 31, 2020 that generated cash flow for the entire six months ended June 30, 2021, an additional 43 self storage properties acquired during the six months ended June 30, 2021 and same store NOI growth. Because 80 self storage properties were acquired after June 30, 2020, our operating results for the six months ended June 30, 2020 were not impacted by them. The increase in our operating cash flows was partially offset by higher cash payments for interest expense.

Investing Activities

Cash used in investing activities was $398.1 million for the six months ended June 30, 2021 compared to $243.9 million for the six months ended June 30, 2020. The primary uses of cash for the six months ended June 30, 2021 were for our acquisition of 43 self storage properties for cash consideration of $383.7 million, capital expenditures of $13.2 million, and deposits for potential acquisitions of $1.1 million. The primary uses of cash for the six months ended June 30, 2020 were for our acquisition of 40 self storage properties for cash consideration of $239.1 million, capital expenditures of $8.6 million, investments in our 2016 Joint Venture of $3.1 million, expenditures for corporate furniture, equipment and other of $0.3 million and deposits for potential acquisitions of $0.3 million partially offset by $7.6 million of proceeds from the sale of equity securities.

Capital expenditures totaled $13.2 million and $8.6 million during the six months ended June 30, 2021 and 2020, 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, 2021 and 2020, are presented below (dollars in thousands):


	Six Months Ended June 30,
	2021		2020
Recurring capital expenditures	$	4,359	$	3,438
Value enhancing capital expenditures	4,880		2,037
Acquisitions capital expenditures	4,051		3,600
Total capital expenditures	13,290		9,075
Change in accrued capital spending	(103)		(492)
Capital expenditures per statement of cash flows	$	13,187	$	8,583

Financing Activities

Cash provided by our financing activities was $258.2 million for the six months ended June 30, 2021 compared to $136.8 million for the six months ended June 30, 2020. Our sources of financing cash flows for the six months ended June 30, 2021 primarily consisted of $491.0 million of borrowings under our Revolver, the $55.0 million 2033 Notes and $226.1 million of proceeds from the issuance of common shares. Our primary uses of financing cash flows for the six months ended June 30, 2021 were for principal payments on existing debt of $405.1 million (which included $399.5 million of principal repayments under the Revolver, a $3.5 million payoff of a fixed rate mortgage and $2.1 million of fixed rate mortgage principal payments), distributions to noncontrolling interests of $45.3 million, payments of dividends to common shareholders of $54.4 million and distributions to preferred shareholders of $6.6 million. Our sources of financing cash flows for the six months ended June 30, 2020 primarily consisted of $311.0 million of borrowings under our Revolver and $16.2 million of proceeds from the issuance of common shares. Our primary uses of financing cash flows for the six months ended June 30, 2020 were for principal payments on existing debt of $103.9 million (which included $100.0 million of principal repayments under the Revolver and $3.9 million of fixed rate mortgage principal payments), distributions to noncontrolling interests of $36.4 million, payments of dividends to common shareholders of $42.4 million and distributions to preferred shareholders of $6.5 million.

Credit Facility and Term Loan Facilities

As of June 30, 2021, our credit facility provided for total borrowings of $1.275 billion, consisting of five components: (i) a Revolver which provides for a total borrowing commitment up to $500.0 million, whereby we may borrow, repay and re-borrow amounts under the Revolver, (ii) a $125.0 million Term Loan A, (iii) a $250.0 million Term Loan B, (iv) a $225.0 million Term Loan C and (v) a $175.0 million Term Loan D. The Revolver matures in January 2024; provided that we may elect to extend the maturity to July 2024 by paying an extension fee of 0.075% of the total borrowing commitment thereunder at the time of extension and meeting other customary conditions with respect to compliance. The Term Loan A matures in January 2023, the Term Loan B matures in July 2024, the Term Loan C matures in January 2025 and the Term Loan D matures in July 2026. The Revolver, Term Loan A, Term Loan B, Term Loan C and Term Loan D are not subject to any scheduled reduction or amortization payments prior to maturity. As of June 30, 2021, we have an expansion option under the credit facility, which, if exercised in full, would provide for a total credit facility of $1.750 billion. As of June 30, 2021, we would have had the capacity to borrow remaining Revolver commitments of $228.8 million while remaining in compliance with the credit facility's financial covenants.

As discussed in Note 13 in Item 1, in July 2021, we received commitments from a syndicated group of lenders to partially exercise the expansion option under our unsecured credit facility for a $100.0 million Term Loan E.

We have a 2023 Term Loan Facility that matures in June 2023 and is separate from the credit facility in an aggregate amount of $175.0 million. As of June 30, 2021 the entire amount was outstanding under the 2023 Term Loan Facility with an effective interest rate of 2.83%. We have an expansion option under the 2023 Term Loan Facility, which, if exercised in full, would provide for total borrowings in an aggregate amount of $400.0 million.

We have a 2028 Term Loan Facility that matures in December 2028 and is separate from the credit facility and 2023 Term Loan Facility in an aggregate amount of $75.0 million. As of June 30, 2021 the entire amount was outstanding under the 2028 Term Loan Facility with an effective interest rate of 4.62%. 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 a 2029 Term Loan Facility that matures in April 2029 and is separate from the credit facility, 2023 Term Loan Facility and 2028 Term Loan Facility in an aggregate amount of $100.0 million. As of June 30, 2021 the entire amount was outstanding under the 2029 Term Loan Facility with an effective interest rate of 4.27%.

2029 and August 2031 Senior Unsecured Notes

On August 30, 2019, our operating partnership issued $100.0 million of 3.98% senior unsecured notes due August 30, 2029 and $50.0 million of 4.08% senior unsecured notes due August 30, 2031 in a private placement to certain institutional investors.

2030 and 2032 Senior Unsecured Notes

On October 22, 2020, our operating partnership issued $150.0 million of 2.99% senior unsecured notes due August 5, 2030 and $100.0 million of 3.09% senior unsecured notes due August 5, 2032 in a private placement to certain institutional investors.

2026, May 2031 and 2033 Senior Unsecured Notes

As discussed in Note 8 in Item 1, on May 3, 2021, our operating partnership entered into an agreement to issue the 2026 Notes, the May 2031 Notes and the 2033 Notes to certain institutional investors. On May 26, 2021, the operating partnership issued the 2033 Notes and as discussed in Note 13 on July 26, 2021 our operating partnership issued the 2026 Notes and the May 2031 Notes.

Fixed Rate Mortgage Payable

On July 9, 2021, we entered into an agreement with a single lender for an $88.0 million debt financing secured by eight of our self storage properties. This interest-only loan matures in July 2028 and has a fixed interest rate of 2.77%.

Equity Transactions

Issuance of Common Shares

As discussed in Note 13 in Item 1, on July 23, 2021, we closed a follow-on public offering of 10,120,000 of common shares, which included 1,320,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at a public offering price of $51.25 per share. We received aggregate net proceeds from the offering of approximately $497.4 million after deducting the underwriting discount and additional expenses associated with the offering.

During the six months ended June 30, 2021, we sold 3,032,726 of our common shares through at the market offerings. The common shares were sold at an average offering price of $42.92 per share, resulting in net proceeds to us of approximately $129.1 million after deducting compensation payable by us to the agents and offering expenses. As discussed in Note 13 in Item 1, subsequent to June 30, 2021, we sold 782,000 common shares through the ATM program at an average offering price of $51.82 per share, resulting in net proceeds to us of approximately $40.0 million, after deducting compensation payable by us to the agents and offering expenses.

During September 2020, we completed an underwritten public offering of 4,500,000 common shares under forward sale agreements at a public offering price of $33.15 per share. The underwriters were granted a 30-day option to purchase up to an additional 675,000 common shares at the same price, which they partially exercised for an additional 400,000 common shares on October 6, 2020. On December 30, 2020, the Company settled a portion of the forward offering by physically delivering 1,850,510 common shares to the forward purchasers for net proceeds of approximately $60.0 million. On March 22, 2021 the Company settled the remaining portion of the forward offering by physically delivering 3,049,490 common shares to the forward purchasers for net proceeds of approximately $97.3 million.

During the six months ended June 30, 2021, after receiving notices of redemption from certain OP unitholders, we elected to issue 312,171 common shares to such holders in exchange for 312,171 OP units in satisfaction of the operating partnership's redemption obligations.

Issuance of OP Equity

In connection with the 43 properties acquired during the six months ended June 30, 2021, we issued $47.0 million of OP equity (consisting of 559,463 OP units and 512,763 subordinated performance units).

As discussed in Note 3 in Item 1, during the six months ended June 30, 2021, the Company issued 63,033 OP units issued upon the conversion of 32,741 subordinated performance units and 142,405 OP units upon the conversion of an equivalent number of LTIP units.

Dividends and Distributions

On May 27, 2021, our board of trustees declared a cash dividend and distribution, respectively, of $0.38 per common share and OP unit to shareholders and OP unitholders of record as of June 15, 2021. On May 27, 2021, our board of trustees also declared cash distributions of $0.375 per Series A Preferred Share and Series A-1 preferred unit to shareholders and unitholders of record as of June 15, 2021. On June 14, 2021, our board of trustees declared cash distributions of $12.1 million, in aggregate, to subordinated performance unitholders of record as of June 15, 2021. Such dividends and distributions were paid on June 30, 2021.

Cash Distributions from our Operating Partnership

Under the LP Agreement of our operating partnership, to the extent that we, as the general partner of our operating partnership, determine to make distributions to the partners of our operating partnership out of the operating cash flow or capital transaction proceeds generated by a real property portfolio managed by one of our PROs, the holders of the series of subordinated performance units that relate to such portfolio are entitled to share in such distributions. Under the LP Agreement of our operating partnership, operating cash flow with respect to a portfolio of properties managed by one of our PROs is generally an amount determined by us, as general partner of our operating partnership, equal to the excess of property revenues over property related expenses from that portfolio. In general, property revenue from the portfolio includes:

(i)all receipts, including rents and other operating revenues;

(ii)any incentive, financing, break-up and other fees paid to us by third parties;

(iii)amounts released from previously set aside reserves; and

(iv)any other amounts received by us, which we allocate to the particular portfolio of properties.

In general, property-related expenses include all direct expenses related to the operation of the properties in that portfolio, including real property taxes, insurance, property-level general and administrative expenses, employee costs, utilities, property marketing expense, property maintenance and property reserves and other expenses incurred at the property level. In addition, other expenses incurred by our operating partnership will also be allocated by us, as general partner, to the property portfolio and will be included in the property-related expenses of that portfolio. Examples of such other expenses include:

(i)corporate-level general and administrative expenses;

(ii)out-of-pocket costs, expenses and fees of our operating partnership, whether or not capitalized;

(iii)the costs and expenses of organizing and operating our operating partnership;

(iv)amounts paid or due in respect of any loan or other indebtedness of our operating partnership during such period;

(v)extraordinary expenses of our operating partnership not previously or otherwise deducted under item (ii) above;

(vi)any third-party costs and expenses associated with identifying, analyzing, and presenting a proposed property to us and/or our operating partnership; and

(vii)reserves to meet anticipated operating expenditures, debt service or other liabilities, as determined by us.

To the extent that we, as the general partner of our operating partnership, determine to make distributions to the partners of our operating partnership out of the operating cash flow of a real property portfolio managed by one of our PROs, operating cash flow from a property portfolio is required to be allocated to OP unitholders and to the holders of series of subordinated performance units that relate to such property portfolio as follows:

First, an amount is allocated to OP unitholders in order to provide OP unitholders (together with any prior allocations of capital transaction proceeds) with a cumulative preferred allocation on the unreturned capital contributions attributed to the OP units in respect of such property portfolio. The preferred allocation for all of our existing portfolios is 6%. As of June 30, 2021, our operating partnership had an aggregate of $2,101.6 million of unreturned capital contributions with respect to common shareholders and OP unitholders, with respect to the various property portfolios.

Second, an amount is allocated to the holders of the series of subordinated performance units relating to such property portfolio in order to provide such holders with an allocation (together with prior distributions of capital transaction proceeds) on their unreturned capital contributions. Although the subordinated allocation for the subordinated performance units is non-cumulative from period to period, if the operating cash flow from a property portfolio related to a series of subordinated performance units is sufficient, in the judgment of the general partner (with the approval of a majority of our independent trustees), to fund distributions to the holders of such series of subordinated performance units, but we, as the general partner of our operating partnership, decline to make distributions to such holders, the amount available but not paid as distributions will be added to the subordinated allocation corresponding to such series of subordinated performance units. The subordinated allocation for the outstanding subordinated performance units is 6%. As of June 30, 2021, an aggregate of $151.5 million of unreturned capital contributions has been allocated to the various series of subordinated performance units.

Thereafter, any additional operating cash flow is allocated to OP unitholders and the applicable series of subordinated performance units equally.

Following the allocation described above, we as the general partner of our operating partnership, will generally cause our operating partnership to distribute the amounts allocated to the relevant series of subordinated performance units to the holders of such series of subordinated performance units. We, as the general partner, may cause our operating partnership to distribute the amounts allocated to OP unitholders or may cause our operating partnership to retain such amounts to be used by our operating partnership for any purpose. Any operating cash flow that is attributable to amounts retained by our operating partnership pursuant to the preceding sentence will generally be available to be allocated as an additional capital contribution to the various property portfolios.

The foregoing description of the allocation of operating cash flow between the OP unitholders and subordinated performance unitholders is used for purposes of determining distributions to holders of subordinated performance units but does not necessarily represent the operating cash flow that will be distributed to OP unitholders (or paid as dividends to holders of our common shares). Any distribution of operating cash flow allocated to the OP unitholders will be made at our discretion (and paid as dividends to holders of our common shares at the discretion of our board of trustees).

Under the LP Agreement of our operating partnership, capital transactions are transactions that are outside the ordinary course of our operating partnership's business, involve the sale, exchange, other disposition, or refinancing of any property, and are designated as capital transactions by us, as the general partner. To the extent the general partner determines to distribute capital transaction proceeds, the proceeds from capital transactions involving a particular property portfolio are required to be allocated to OP unitholders and to the series of subordinated performance units that relate to such property portfolio as follows:

First, an amount determined by us, as the general partner, of such capital transaction proceeds is allocated to OP unitholders in order to provide OP unitholders (together with any prior allocations of operating cash flow) with a cumulative preferred allocation on the unreturned capital contributions attributed to the OP unitholders in respect of such property portfolio that relate to such capital transaction plus an additional amount equal to such unreturned capital contributions.

Second, an amount determined by us, as the general partner, is allocated to the holders of the series of subordinated performance units relating to such property portfolio in order to provide such holders with a non-cumulative subordinated allocation on the unreturned capital contributions made by such holders in respect of such property portfolio that relate to such capital transaction plus an additional amount equal to such unreturned capital contributions.

The preferred allocation and subordinated allocation with respect to capital transaction proceeds for each portfolio is equal to the preferred allocation and subordinated allocation for distributions of operating cash flow with respect to that portfolio.

Thereafter, any additional capital transaction proceeds are allocated to OP unitholders and the applicable series of subordinated performance units equally.

Following the allocation described above, we, as the general partner of our operating partnership, will generally cause our operating partnership to distribute the amounts allocated to the relevant series of subordinated performance units to the holders of such series of subordinated performance units. We, as general partner of our operating partnership, may cause our operating partnership to distribute the amounts allocated to the OP unitholders or may cause our operating partnership to retain such amounts to be used by our operating partnership for any purpose. Any capital transaction proceeds that are attributable to amounts retained by our operating partnership pursuant to the preceding sentence will generally be available to be allocated as an additional capital contribution to the various property portfolios.

The foregoing allocation of capital transaction proceeds between the OP unitholders and subordinated performance unitholders is used for purposes of determining distributions to holders of subordinated performance units but does not necessarily represent the capital transaction proceeds that will be distributed to OP unitholders (or paid as dividends to holders of our common shares). Any distribution of capital transaction proceeds allocated to the OP unitholders will be made at our discretion (and paid as dividends to holders of our common shares at the discretion of our board of trustees).

Allocation of Capital Contributions

We, as the general partner of our operating partnership, in our discretion, have the right to increase or decrease, as appropriate, the amount of capital contributions allocated to our operating partnership in general and to each series of subordinated performance units to reflect capital expenditures made by our operating partnership in respect of each portfolio, the sale or refinancing of all or a portion of the properties comprising the portfolio, the distribution of capital transaction proceeds by our operating partnership, the retention by our operating partnership of cash for working capital purposes and other events impacting the amount of capital contributions allocated to the holders. In addition, to avoid conflicts of interests, any decision by us to increase or decrease allocations of capital contributions must also be approved by a majority of our independent trustees.

Off-Balance Sheet Arrangements

Except as disclosed in the notes to our financial statements, as of June 30, 2021, 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, 2021, 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.

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, 2021, we had $265.5 million of debt subject to variable interest rates (excluding variable-rate debt subject to interest rate swaps). If one-month LIBOR 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 $2.7 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 three months ended June 30, 2021 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.

Following a specified lock up period after the date of issuance set forth above, 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 has elected 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.

Following a two-year lock-up period, holders of subordinated performance units may elect, only upon the achievement of certain performance thresholds relating to the properties to which such subordinated performance units relate, to convert all or a portion of such subordinated performance units into OP units one time each year by submitting a completed conversion notice prior to December 1 of such year. All duly submitted conversion notices will become effective on the immediately following January 1. For additional information about the conversion or exchange of subordinated performance units into OP units, see Note 9 in Item 1 of this report.

As of August 3, 2021, other than those OP units held by the Company, after reflecting the transactions described herein, 32,918,141 OP units of its operating partnership were outstanding (including 778,362 outstanding LTIP units in the operating partnership and 1,924,918 outstanding OP units ("DownREIT OP units") in certain consolidated subsidiaries of the operating partnership, which are convertible into, or exchangeable for, OP units on a one-for-basis, subject to certain conditions) and 13,858,875 subordinated performance units (including 4,337,111 subordinated performance units in certain subsidiaries of the operating partnership ("DownREIT subordinated performance units").
