Tamara Fischer, President and Chief Executive Officer, commented, "We closed out 2020 on a positive note with excellent operating results despite the continued economic stress resulting from the pandemic. Our fourth quarter same store revenues grew by 4.8% year-over-year and same store occupancy numbers remain at record levels. Our acquisition volume also accelerated during the fourth quarter with the addition of over a quarter of a billion dollars of self storage properties to our wholly-owned portfolio. These favorable trends continued into the first quarter, marking a strong start to 2021."

Net income increased $5.7 million for the fourth quarter of 2020 and $13.5 million for the year ended December 31, 2020 ("year-to-date") as compared to the same periods in 2019. The increase for the fourth quarter of 2020 resulted primarily from additional NOI generated from the 77 wholly-owned self storage properties acquired during the year ended December 31, 2020 and earnings from the Company's unconsolidated real estate ventures partially offset by increases in depreciation and amortization, interest expense and non-operating expense. The year-to-date increase was the result of additional NOI generated from the 77 wholly-owned self storage properties acquired during 2020 and a decrease in GAAP losses from the Company's unconsolidated real estate ventures partially offset by increases in depreciation and amortization, interest expense, non-operating expense, acquisition costs and a decrease in gains from the sale of self storage properties.
The increases in FFO and Core FFO for the fourth quarter of 2020 and year-to-date were primarily the result of incremental NOI from properties acquired during the year ended December 31, 2020 and decreases in distributions to subordinated performance unitholders.

The increase for the fourth quarter of 2020 was driven primarily by a 400 basis point increase in average occupancy partially offset by 0.1% decrease in average annualized rental revenue per occupied square foot. The year-to-date increase in same store total revenue was driven primarily by a 100 basis point increase in average occupancy and a 0.2% increase in average annualized rental revenue per occupied square foot.

Investment Activity
During the fourth quarter, NSA invested approximately $260.5 million in the acquisition of 33 self storage properties and two expansion projects to existing properties consisting of approximately 2.5 million rentable square feet configured in approximately 16,750 storage units.

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

(1) Amounts represent distributions declared for subordinated performance unitholders and DownREIT subordinated performance unitholders for the periods presented.
(2) NSA combines OP units and DownREIT OP units with common shares because, after the applicable lock-out periods, OP units in the Company's operating partnership are redeemable for cash or, at NSA's option, exchangeable for common shares on a one-for-one basis and DownREIT OP units are also redeemable for cash or, at NSA's option, exchangeable for OP units in the Company's operating partnership on a one-for-one basis, subject to certain adjustments in each case. Subordinated performance units, DownREIT subordinated performance units and LTIP units may also, under certain circumstances, be convertible into or exchangeable for common shares (or other units that are convertible into or exchangeable for common shares). See footnote(4) for additional discussion of subordinated performance units, DownREIT subordinated performance units, and LTIP units in the calculation of FFO and Core FFO per share and unit.
(3) Represents the dilutive effect of the forward offering from the application of the treasury stock method.

(4) Adjustment accounts for the difference between the weighted average number of shares used to calculate diluted earnings per share and the weighted average number of shares used to calculate FFO and Core FFO per share and unit. Diluted earnings per share is calculated using the two-class method for the company's restricted common shares and the treasury stock method for certain unvested LTIP units, and assumes the conversion of vested LTIP units into OP units on a one-for-one basis and the hypothetical conversion of subordinated performance units, and DownREIT subordinated performance units into OP units, even though such units may only be convertible into OP units (i) after a lock-out period and (ii) upon certain events or conditions. For additional information about the conversion of subordinated performance units and DownREIT subordinated performance units into OP units, see Note 10 to the Company's most recent Annual Report on Form 10-K, filed with the Securities and Exchange Commission. The computation of weighted average shares and units for FFO and Core FFO per share and unit includes all restricted common shares and LTIP units that participate in distributions and excludes all subordinated performance units and DownREIT subordinated performance units because their effect has been accounted for through the allocation of FFO to the related unitholders based on distributions declared.
(5) 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(4).

(3) Balances exclude 252,894 long-term incentive plan ("LTIP") units which only vest and participate in dividend distributions upon the future contribution of properties from the PROs or the completion of expansion projects.
(4) If converted balance assumes that each subordinated performance unit (including each DownREIT subordinated performance unit) is convertible into OP units, notwithstanding the two-year lock-out period on conversions for certain series of subordinated performance units, and that each subordinated performance unit would on average convert on a hypothetical basis into an estimated 1.23 OP units based on historical financial information for the trailing twelve months ended December 31, 2020. The hypothetical conversions are calculated by dividing the average cash available for distribution, or CAD, per subordinated performance unit by 110% of the CAD per OP unit over the same period. The Company anticipates that as CAD grows over time, the conversion ratio will also grow, including to levels that may exceed these amounts.

(1) Values represent entire unconsolidated real estate ventures at 100%, not NSA's proportionate share. NSA's ownership in each of the unconsolidated real estate ventures is 25%.
(2) NSA's proportionate share of its unconsolidated real estate ventures is derived by applying NSA's 25% ownership interest to each line item in the GAAP financial statements of the unconsolidated real estate ventures to calculate NSA's share of that line item. NSA believes this information offers insights into the financial performance of the Company, although the presentation of such information, and its combination with NSA's consolidated results, may not accurately depict the legal and economic implications of holding a noncontrolling interest in the unconsolidated real estate ventures. The operating agreements of the unconsolidated real estate ventures provide for the distribution of net cash flow to the unconsolidated real estate ventures' investors no less than monthly, generally in proportion to the investors’ respective ownership interests, subject to a promoted distribution to NSA upon the achievement of certain performance benchmarks by the non-NSA investor.
