Financial Results

Add back acquisition costs, organizational and offering expenses, and loss on early extinguishment of debt	1,633		6,551			2,290			6,968
Core FFO	$	8,471	$	2,274		$	12,888		$	3,063

Core FFO per share and unit	$	0.22	$	0.20		$	0.43		$	0.29

FFO was $6.8 million, or $0.18 per share, for the second quarter of 2015, compared to a FFO net loss of $4.3 million, or $0.37 per share, for the second quarter of 2014. Core FFO was $8.5 million, or $0.22 per share for the second quarter of 2015, an increase of 10% per share compared to Core FFO of $2.3 million, or $0.20 per share, for the second quarter of 2014. The increases in FFO and Core FFO were primarily the result of an additional $7.6 million of NOI from the acquisition of 73 self storage properties acquired between July 1, 2014 and June 30, 2015, and reductions in acquisition costs, partially offset by increases in general and administrative expenses.

Net income attributable to the Company was $93,000 for the second quarter of 2015, compared to a net loss of $6.2 million for the second quarter of 2014. The increase in net income was primarily due to an increase in NOI resulting from self storage properties NSA acquired during 2014 and 2015, and reductions in acquisition costs partially offset by increases in depreciation and amortization, general and administrative expenses and a decrease in gain on sale of self storage properties.

Total Portfolio Operating Results



($ in thousands, except per square foot data)	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014

Total portfolio revenues were $31.7 million for the second quarter of 2015, an increase of 95.2% compared to total revenues of $16.2 million for the second quarter of 2014. Total revenue increases were driven by a

210 basis point increase in average occupancy for the second quarter of 2015 compared to the second quarter of 2014, combined with a 9.2% increase in average annualized rental revenue per occupied square foot compared to the second quarter of 2014 and a significant increase in acquisition activity.

Total portfolio NOI was $20.8 million for the second quarter of 2015, an increase of over 100% compared to NOI of $10.2 million for the second quarter of 2014.

Same store revenues were $14.7 million for the second quarter of 2015, an increase of 6.8% compared to $13.8 million for the second quarter of 2014. Revenue increases were driven by a 270 basis point increase in average occupancy for the second quarter of 2015 compared to the second quarter of 2014, combined with a 3.6% increase in average annualized rental revenue per occupied square foot compared to the prior year.

Same store NOI was $9.6 million for the second quarter of 2015, an increase of 11.8% compared to same store NOI of $8.6 million for the second quarter of 2014. The increase was driven by an average occupancy gain of 270 basis points and an average annualized rental revenue per occupied square foot increase of 3.6% for the second quarter of 2015 compared to the second quarter of 2014.

Investment Activity

NSA acquired 21 self storage properties in the second quarter of 2015 for an investment of approximately $93 million, composed of approximately 1.3 million rentable square feet configured in approximately 9,300 storage units.

Since July 1, 2015, the Company acquired 12 properties valued at approximately $94 million, composed of approximately 900,000 rentable square feet configured in approximately 6,800 storage units.

The Company has also entered agreements to acquire an additional four self storage properties and has exercised a right of first refusal to acquire a portfolio of 14 properties. The total value of the 18 properties is approximately $80 million. The Company expects to close those transactions by mid-fourth quarter of 2015.

Debt and Credit Facility Activity

Following the completion of the Company's IPO during the second quarter of 2015, NSA repaid $229.8 million of outstanding indebtedness at a weighted average effective rate of 4.0%. As a result of the overall reduction in NSA's outstanding indebtedness, pricing grids for the Company's revolving line of credit and term loan were reduced by 100 basis points to interest rates equal to one-month LIBOR plus 1.60% and one-month LIBOR plus 1.50%, respectively.

The Company is in the process of expanding its credit facility to $550 million, which will be comprised of a $200 million term loan and a $350 million revolving line of credit.

Dividends

On June 3, 2015, NSA's Board of Trustees declared a quarterly dividend of $0.15 per common share which was paid on July 15, 2015 to holders of record at June 30, 2015.

The second quarter 2015 distribution of $0.15 per operating partnership ("OP") unit, combined with the $0.04 per OP unit distribution for the period from April 1 through April 20, 2015, paid by the Company on April 30, 2015, resulted in a total second quarter 2015 distribution rate of $0.19 per OP unit, comparable to the Company's distribution paid to OP unitholders for the first quarter of 2015.

NSA anticipates this dividend rate of $0.19 per share, per quarter, will continue for the near term, and its Board of Trustees will continue to review the Company's dividend policy on a quarterly basis.

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).

The presentation 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. For the three months ended June 30, 2014, these distributions were declared and paid to unitholders of record as of June 30, 2014 during the period subsequent to June 30, 2014, and therefore the amounts are not reflected in the historical financial statements 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). Subordinated performance units and DownREIT subordinated units have been excluded from the calculations of FFO and Core FFO per share and unit as their effect is anti-dilutive.
(3) Amount for the six months ended June 30, 2014 includes 2,060,711 OP units outstanding for the entire period which were issued in connection with the contribution of 65 self storage properties on April 1, 2014 by SecurCare Portfolio Holdings, LLC and SecurCare Value Properties, Ltd. (collectively, "NSA Predecessor"), entities whose principal owner is the Company's chief executive officer. For financial reporting purposes, NSA Predecessor contributions are reported as a reorganization of entities under common control whereby the contributed self storage properties are included in the Company's results of operations for the entirety of the six months ended June 30, 2014 and have been recorded in the Company's financial statements at NSA Predecessor's depreciated historical cost basis.
(4) LTIP units have been excluded from the calculations of weighted average shares and units outstanding prior to April 28, 2015 because such units did not participate in distributions prior to the Company’s initial public offering.

(3) Balances exclude 522,900 long term incentive plan units which only vest and participate in dividend distributions upon the future contribution of properties from the PROs.
(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, and that each subordinated performance unit would on average convert on a hypothetical basis into an estimated 1.08 OP units based on historical financial information for the three months ended June 30, 2015. 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. We anticipate that as our CAD grows over time, the conversion ratio will also grow, including to levels that may exceed these amounts.

Glossary

This Earnings Release and Supplemental Information include certain financial and operating measures used by NSA management that are not calculated in accordance with accounting principles generally accepted in the United States, or GAAP. NSA's definitions and calculations of these non-GAAP financial and operating measures and other terms may differ from the definitions and methodologies used by other real estate companies and, accordingly, may not be comparable. These non-GAAP financial and operating measures should not be considered an alternative to GAAP net income or any other GAAP measurement of performance and should not be considered an alternative measure of liquidity.

ANNUALIZED RENTAL REVENUE: Annualized rental revenue is annualized total revenue per our statements of operations (which includes fees and is net of any discounts).

AVERAGE ANNUALIZED CONTRACTUAL RENT PER OCCUPIED SQUARE FOOT: Contractual rent per occupied square foot represents annualized contractual rents per occupied square foot without reductions for promotional discounts and excluding late charges and administrative fees.

AVERAGE ANNUALIZED RENTAL REVENUE PER OCCUPIED SQUARE FOOT: Average annualized rental revenue per occupied square foot is computed by dividing annualized rental revenue by average occupied square feet.

AVERAGE OCCUPANCY: Average occupancy is calculated based on the average of the month-end occupancy immediately preceding the period presented and the month-end occupancies included in the respective period presented.

CAPITAL EXPENDITURES DEFINITIONS

ACQUISITIONS CAPITAL EXPENDITURES: Acquisitions capital expenditures represents the portion of capital expenditures capitalized during the current period that were identified and underwritten prior to a property's acquisition.

RECURRING CAPITAL EXPENDITURES: Recurring capital expenditures represents the portion of capital expenditures that are deemed to replace the consumed portion of acquired capital assets.

REVENUE ENHANCING CAPITAL EXPENDITURES: Revenue enhancing capital expenditures represents the portion of capital expenditures that are made to enhance the revenue, value, or useful life of an asset from its original purchase condition.

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. 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; and by subtracting gains on sale of properties and debt forgiveness. 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 its usefulness as a comparative measure.

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, income from operations, and net income (loss).

FUNDS FROM OPERATIONS: Funds from operations, or FFO, is a widely used performance measure for real estate companies and is provided here as a supplemental measure of our operating performance. The April 2002 National Policy Bulletin of NAREIT, which we refer to as the White Paper, as amended, defines FFO as net income (as determined under GAAP), excluding gains (or losses) from sales of real estate and related impairment charges, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. We include amortization of customer in-place leases in real estate depreciation and amortization in the calculation of FFO because we believe the amortization of customer in-place leases is analogous to real estate depreciation, as the value of such intangibles is inextricably connected to the real estate acquired. Distributions 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 the purpose of calculating FFO attributable to common shareholders, OP unitholders, and LTIP unitholders. 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 and gains (losses) on early extinguishment of debt.

Management uses FFO and Core FFO as a key performance indicator 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.

LTIP UNITS: Long-term incentive plan units.

NET DEBT TO ANNUALIZED CURRENT QUARTER ADJUSTED EBITDA: We calculate net debt to Adjusted EBITDA as total debt (inclusive of $6.4 million of fair value of debt adjustments) less cash and cash equivalents, divided by annualized current quarter Adjusted EBITDA.

NET OPERATING INCOME: We define net operating income, or NOI, as net income (loss), as determined under GAAP, plus general and administrative expense, depreciation and amortization, interest expense, loss on early extinguishment of debt, acquisition costs, organizational and offering expenses, impairment of long-lived assets, losses on the sale of properties and non-operating expense and by subtracting gains on sale of properties, debt forgiveness, and non-operating income. 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 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, income from operations and net loss.

NET OPERATING INCOME MARGIN: The ratio of NOI divided by total revenue.

NON-SAME STORE PORTFOLIO: Non-Same Store portfolio comprises those properties that do not meet the Same Store portfolio property definition.

OCCUPANCY AT PERIOD END: Represents total occupied rentable square feet divided by total rentable square feet at period end.
