COVID-19 Pandemic – During the quarter and nine months ended September 30, 2021, NNN and its tenants continue to be impacted by the novel strain of coronavirus ("COVID-19") pandemic which has resulted in the loss of revenue for certain tenants and challenged their ability to pay rent. NNN has entered into rent deferral lease amendments with certain tenants (See Note 2).

Principles of Consolidation – NNN’s condensed consolidated financial statements include the accounts of each of the respective majority owned and controlled affiliates, including transactions whereby NNN has been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codifications ("ASC") guidance included in Consolidation. All significant intercompany account balances and transactions have been eliminated.

Real Estate Portfolio – NNN records the acquisition of real estate at cost, including acquisition and closing costs. The cost of Properties developed or funded by NNN includes direct and indirect costs of construction, property taxes, interest and other miscellaneous costs incurred during the development period until the project is substantially complete and available for occupancy. NNN recorded $215,000 and $1,218,000 in capitalized interest during the development period for the nine months ended September 30, 2021 and 2020, respectively, of which $87,000 and $332,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Purchase Accounting for Acquisition of Real Estate Subject to a Lease – In accordance with the FASB guidance on business combinations, consideration for the real estate acquired is allocated to the acquired tangible assets, consisting of land, building and tenant improvements, and, if applicable, to identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, as applicable, based on their respective fair values.

The fair value estimate is sensitive to significant assumptions, such as establishing a range of relevant market assumptions for land, building and rent and where the acquired property falls within that range. These market assumptions for land, building

11

and rent use the most relevant comparable properties for an acquisition. The final range relies upon ranking comparable properties' attributes from most to least similar.

The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, and the "as-if-vacant" value is then allocated to land, building and tenant improvements based on the determination of their fair values.

In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded as other assets or liabilities based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining term of the lease and the renewal option terms if it is probable that the tenant will exercise options. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining terms of the respective leases. The capitalized below-market lease values are amortized as an increase to rental income over the initial term unless the Company believes that it is likely that the tenant will renew the lease for an option term whereby the Company amortizes the value attributable to the renewal over the renewal period.

The aggregate value of other acquired intangible assets, consisting of in-place leases, is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates over (ii) the estimated fair value of the property as-if-vacant, determined as set forth above. The value of in-place leases exclusive of the value of above-market and below-market in-place leases is amortized to expense over the remaining non-cancelable periods of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off in that period. The value of tenant relationships is reviewed on individual transactions to determine if future value was derived from the acquisition.

Lease Accounting – In accordance with FASB Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," ("ASC 842"), NNN recorded Right-Of-Use assets and operating lease liabilities as lessee under operating leases.

In July 2021, the FASB issued ASU 2021-05, which affects lessors with lease contracts that (i) have variable lease payments that do not depend on a reference index or a rate and (ii) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. NNN has reviewed all existing leases and determined this update has no effect on the current portfolio, but will apply ASU 2021-05 prospectively to leases that commence or are modified in the future.

In April 2020, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. NNN elected to make this policy election for COVID-19 lease concessions, including the rent deferral lease amendments effective during the year ended December 31, 2020 and the quarter and nine months ended September 30, 2021.

In accordance with ASC 842, NNN reviews the collectability of its lease payments on an ongoing basis. NNN considers collectability indicators when analyzing accounts receivable (and accrued rent) and historical bad debt levels, tenant credit-worthiness and current economic trends, all of which assists in evaluating the probability of outstanding and future lease payment collections. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition bankruptcy claims. At the point NNN deems the collection of lease payments not probable, previously recognized rental revenue and any related accrued rent are reversed and, subsequently, any lease revenue is only recognized when cash receipts are received. As a result of the review of lease payments collectability, no outstanding receivables and related accrued rent were written off during the quarter and nine months ended September 30, 2021, and no tenants were reclassified as cash basis for accounting purposes.

NNN includes an allowance for doubtful accounts in rental income on the Consolidated Statements of Income and Comprehensive Income.

As of September 30, 2021, approximately six percent of total Properties, and approximately seven percent of aggregate gross leasable area held in the Property Portfolio, was leased to 11 tenants that NNN has determined to recognize revenue on a cash basis. During the nine months ended September 30, 2021 and 2020, NNN recognized $37,999,000 and $930,000, respectively, of rental income from certain tenants for periods following their classification to cash basis for accounting, of which $13,630,000 and $726,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Impairment – Real Estate – NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are

12

currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, which provide for cash flows over this term. NNN generally intends to hold these assets for the long-term, therefore, a temporary change in cash flows due to COVID-19 alone would not be an indicator of impairment.

Credit Losses on Financial Instruments – FASB ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” (“ASC 326”) requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings. The guidance requires a lifetime credit loss expected at inception and requires pooling of assets, which share similar risk characteristics. NNN is required to evaluate current economic conditions, as well as, make future expectations of economic conditions. In addition, the measurement of the expected credit loss is over the asset’s contractual term.

As of September 30, 2021 and December 31, 2020, NNN had mortgages receivable of $2,117,000 and $2,482,000, respectively, included in other assets on the Condensed Consolidated Balance Sheets, net of $135,000 and $158,000 allowance for credit loss, respectively. NNN measures the allowance for credit loss based on the fair value of the collateral and the historical collectability trend analysis over 15 years.

Debt Costs – Line of Credit Payable – Debt costs incurred in connection with NNN's $1,100,000,000 line of credit have been deferred and are being amortized to interest expense over the term of the loan commitment using the straight-line method, which approximates the effective interest method. NNN has recorded debt costs associated with the line of credit as an asset, in debt costs on the Condensed Consolidated Balance Sheets.

Debt Costs – Notes Payable – Debt costs incurred in connection with the issuance of NNN’s notes payable have been deferred and are being amortized to interest expense over the term of the respective debt obligation using the effective interest method. These costs of $38,145,000 and $31,140,000, as of September 30, 2021 and December 31, 2020, respectively, are included in notes payable on the Condensed Consolidated Balance Sheets net of accumulated amortization of $8,670,000 and $9,317,000, respectively.

Earnings Per Share – Earnings per share have been computed pursuant to the FASB guidance included in Earnings Per Share. The guidance requires classification of the Company’s unvested restricted share units, which carry rights to receive nonforfeitable dividends, as participating securities requiring the two-class method of computing earnings per share. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period.

Fair Value Measurement – NNN’s estimates of fair value of financial and non-financial assets and liabilities are based on the framework established in the fair value accounting guidance. The framework specifies a hierarchy of valuation inputs which was established to increase consistency, clarity and comparability in fair value measurements and related disclosures. The guidance describes a fair value hierarchy based upon three levels of inputs that may be used to measure fair value, two of which are considered observable and one that is considered unobservable. The following describes the three levels:

•Level 1 – Valuation is based upon quoted prices in active markets for identical assets or liabilities.

•Level 2 – Valuation is based upon inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 – Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include option pricing models, discounted cash flow models and similar techniques.

(1)	Additional disclosure is included in Note 6 – Derivatives.
(2)	Recorded in interest expense on the Condensed Consolidated Statements of Income and Comprehensive Income.

Use of Estimates – Additional critical accounting policies of NNN include management’s estimates and assumptions relating to the reporting of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities and are required to prepare the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Significant accounting policies include management’s estimates of the useful lives used in calculating depreciation expense relating to real estate asset purchase accounting for acquisition of real estate subject to a lease, the recoverability of the carrying value of long-lived assets and management's evaluation of the probability of outstanding and future lease payment collections. Actual results could differ from those estimates. 

Note 2 – Real Estate:

Real Estate – Portfolio

Leases – At September 30, 2021, NNN’s real estate portfolio had a weighted average remaining lease term of 10.6 years and consisted of 3,187 leases classified as operating leases and an additional six leases accounted for as direct financing.

The following is a summary of the general structure of the leases in the Property Portfolio, although the specific terms of each lease can vary significantly. Generally, the Property leases provide for initial terms of 10 to 20 years. The Properties are generally leased under net leases, pursuant to which the tenant typically bears responsibility for substantially all property costs and expenses associated with ongoing maintenance, repair, replacement and operation of the property, including utilities, property taxes and property and liability insurance. Certain Properties are subject to leases under which NNN retains responsibility for specific costs and expenses of the Property. NNN's leases provide for annual base rental payments (generally payable in monthly installments), and generally provide for limited increases in rent as a result of (i) increases in the Consumer Price Index ("CPI"), (ii) fixed increases, or, to a lesser extent, (iii) increases in the tenant’s sales volume.

Generally, NNN's leases provide the tenant with one or more multi-year renewal options, subject to generally the same terms and conditions provided under the initial lease term, including rent increases. NNN’s lease term is based on the non-cancellable base term unless economic incentives make it reasonably certain that an option period to extend the lease will be exercised, in which event NNN includes the options. Some of the leases also provide that in the event NNN wishes to sell the Property subject to that lease, NNN first must offer the lessee the right to purchase the Property on the same terms and conditions as any offer which NNN intends to accept for the sale of the Property.

As of September 30, 2021, NNN has entered into rent deferral lease amendments with certain tenants, for an aggregate $4,758,000 and $52,019,000 of rent originally due for the years ending December 31, 2021 and 2020, respectively. The rent deferral lease amendments require the deferred rents to be repaid at a later time during the lease term. Approximately $3,259,000 of deferred rent was repaid in 2020 and approximately $6,068,000 and $27,087,000 of deferred rent was repaid during the quarter and nine months ended September 30, 2021, respectively. An additional $4,689,000 is due in 2021, with the remaining deferred rent coming due periodically by December 31, 2025.

Historical rent collections and rent relief requests may not be indicative of collections and requests in the future. Depending on macroeconomic conditions and their impact on a tenant's business and operations, deferred rents may be difficult to collect.

	$	180,024	$	157,865	$	537,226	$	495,891

Some leases provide for a free rent period or scheduled rent increases throughout the lease term. Such amounts are recognized on a straight-line basis over the terms of the leases.

For the nine months ended September 30, 2021 and 2020, NNN recognized ($19,427,000) and $33,022,000, respectively, of accrued rental income, net of reserves, of which ($3,509,000) and $2,305,000 of such income, net of reserves, was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Included in accrued rental income are the impacts of the rent deferral lease amendments NNN entered into as a result of the COVID-19 pandemic. During the nine months ended September 30, 2021 and 2020, NNN recorded ($21,996,000) and $38,938,000, respectively, of net straight-line accrued rental income related to such amendments, of which ($4,294,000) and $8,499,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

At September 30, 2021 and December 31, 2020, the balance of accrued rental income was $34,341,000 and $53,958,000, respectively, net of allowance of $4,922,000 and $6,947,000, respectively.

The amounts amortized as a net increase to rental income for above-market and below-market in-place leases for the nine months ended September 30, 2021 and 2020, were $430,000 and $711,000, respectively, of which $156,000 and $301,000 was recorded for the quarters ended September 30, 2021 and 2020, respectively. The value of in-place leases amortized to expense for the nine months ended September 30, 2021 and 2020, was $5,451,000 and $6,364,000, respectively, of which $1,840,000 and $2,027,000 was recorded for the quarters ended September 30, 2021 and 2020, respectively.

Real Estate – Held For Sale

On a quarterly basis, the Company evaluates its Properties for held for sale classification based on specific criteria as outlined in ASC 360, Property, Plant and Equipment, including management’s intent to commit to a plan to sell the asset. NNN anticipates the disposition of Properties classified as held for sale to occur within 12 months. As of September 30, 2021, NNN had five of its Properties categorized as held for sale. NNN's real estate held for sale at December 31, 2020, included five Properties, all of which were sold in 2021. Real estate held for sale consisted of the following as of (dollars in thousands):

Real Estate – Commitments

NNN has committed to fund construction on 10 Properties. The improvements on such Properties are estimated to be completed within 12 months. These construction commitments, as of September 30, 2021, are outlined in the table below (dollars in thousands):

Total commitment(1)	$	39,122
Less amount funded		17,395
Remaining commitment	$	21,727

(1) Includes land, construction costs, tenant improvements, lease costs and capitalized interest.

Real Estate – Impairments

NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, which provide for cash flows over this term. NNN generally intends to hold these assets for the long-term, therefore, a temporary change in cash flows due to COVID-19 alone would not be an indicator of impairment.

As a result of NNN's review of long-lived assets, including identifiable intangible assets, NNN recognized real estate impairments, net of recoveries as summarized in the table below (dollars in thousands):

	Quarter Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Total real estate impairments, net of recoveries	$	4,781	$	5,695	$	14,647	$	33,062
Number of Properties:
Vacant		5		1		19		10
Occupied		2		—		10		13

The valuation of impaired assets is determined using widely accepted valuation techniques including discounted cash flow analysis, income capitalization, analysis of recent comparable sales transactions, actual sales negotiations and bona fide purchase offers received from third parties, which are Level 3 inputs. NNN may consider a single valuation technique or multiple valuation techniques, as appropriate, when estimating the fair value of its real estate.

Note 3 – Line of Credit Payable:

In June 2021, NNN amended and restated its credit agreement to increase the borrowing capacity under its unsecured revolving credit facility from $900,000,000 to $1,100,000,000 and amended certain other terms under the former revolving credit facility (as the context requires, the previous and new revolving credit facility, the "Credit Facility"). The Credit Facility had no weighted average outstanding balance during the nine months ended September 30, 2021. The Credit Facility matures in June 2025, unless the Company exercises its options to extend maturity to June 2026. The Credit Facility bears interest at LIBOR plus 77.5 basis points; however, such interest rate may change pursuant to a tiered interest rate structure based on NNN's debt rating. Additionally, as part of NNN's environmental, social and governance ("ESG") initiative, pricing may be reduced if specified ESG metrics are achieved. The Credit Facility also includes an accordion feature which permits NNN to increase the facility size up to $2,000,000,000, subject to lender approval. In connection with the Credit Facility, NNN incurred loan costs of $7,439,000 which are included in debt costs on the Condensed Consolidated Balance Sheet. As of September 30, 2021, there was no outstanding balance and $1,100,000,000 was available for future borrowings under the Credit Facility, and NNN was in compliance with each of the financial covenants.

Note 4 – Notes Payable:

In 2021, NNN filed prospectus supplements to the prospectus contained in its August 2020 shelf registration statement and issued $450,000,000 aggregate principal amount of 3.500% notes due April 2051 (the “2051 Notes”) and $450,000,000 aggregate principal amount of 3.000% notes due April 2052 (the "2052 Notes" and, together with the 2051 Notes, the "Notes"). Each note issuance is summarized in the table below (dollar in thousands):

(1)	The note discounts are amortized to interest expense over the respective term of each debt obligation using the effective interest method.
(2)	Includes the effects of the discount at issuance.
(3)	NNN entered into forward swaps which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt. Upon the issuance of the 2052 Notes, NNN terminated such derivatives, and the resulting fair value was deferred in accumulated other comprehensive income (loss) and is being amortized over the term of the respective notes using the effective interest method. Additional disclosure is included in Note 6 – Derivatives.

Each series of Notes is a senior unsecured obligation of NNN and is subordinated to all secured debt of NNN and to the debt and other liabilities of NNN's subsidiaries. Each series of Notes is redeemable at NNN's option, at any time, in whole or in part, at a redemption price equal to (i) the sum of the outstanding principal amount of the notes being redeemed plus accrued interest thereon, up to but not including the redemption date, and (ii) the make-whole amount, if any, as defined in the applicable supplemental indenture related to the notes.

In connection with the Notes, NNN incurred debt issuance costs totaling $10,144,000 consisting primarily of underwriting discounts and commissions, legal and accounting fees, rating agency fees and printing expenses. Debt issuance costs for all note issuances have been deferred and presented as a reduction to notes payable and are being amortized over the term of the respective notes using the effective interest method.

In March 2021, NNN redeemed the $350,000,000 3.300% notes payable that were due in April 2023. The notes were redeemed at a price equal to 100% of the principal amount, plus (i) a make-whole amount of $21,328,000 which is included in loss on early extinguishment of debt on the Condensed Consolidated Statement of Income and Comprehensive Income, and (ii) accrued and unpaid interest.

Note 5 – Stockholders' Equity:

In August 2020, NNN filed a shelf registration statement with the Securities and Exchange Commission (the "Commission") which was automatically effective and permits the issuance by NNN of an indeterminate amount of debt and equity securities.

Note 6 – Derivatives:

In accordance with the guidance on derivatives and hedging, NNN records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or a firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

NNN’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements or other identified risks. To accomplish this objective, NNN primarily uses treasury locks, forward starting swaps and interest rate swaps as part of its cash flow hedging strategy. Treasury locks and forward starting swaps are used to hedge forecasted debt issuances. Treasury locks designated as cash flow hedges lock in the yield/price of a treasury security. Forward starting swaps also lock the associated swap spread. Interest rate swaps designated as cash flow hedges are used to hedge the variable cash flows associated with floating rate debt and involve the receipt or payment of variable rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount.

For derivatives designated as cash flow hedges, the change in the fair value of the derivative is initially reported in other comprehensive income (loss) (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings.

NNN discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated or exercised, the derivative is re-designated as a hedging instrument or management determines that designation of the derivative as a hedging instrument is no longer appropriate.

When hedge accounting is discontinued, NNN recognizes any changes in its fair value in earnings and continues to carry the derivative on the balance sheet or may choose to settle the derivative at that time with a cash payment or receipt. NNN records a cash settlement of forward starting swaps in the Condensed Consolidated Statements of Cash Flows as an operating activity.

The following table outlines NNN's terminated derivatives which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt (dollars in thousands):

Notes Payable	Terminated	Description	Aggregate Notional Amount		Liability (Asset) Fair Value When Terminated			Fair Value Deferred In Other Comprehensive Income (1)
2024	May 2014	Three forward starting swaps	$	225,000	$	6,312		$	6,312
2025	October 2015	Four forward starting swaps		300,000		13,369			13,369
2026	December 2016	Two forward starting swaps		180,000		(13,352	)		(13,345	)
2027	September 2017	Two forward starting swaps		250,000		7,690			7,688
2028	September 2018	Two forward starting swaps		250,000		(4,080	)		(4,080	)
2030	March 2020	Three forward starting swaps		200,000		13,141			13,141
2052	September 2021	Two forward starting swaps		120,000		1,584			1,584

(1) The amount reported in accumulated other comprehensive income (loss) will be reclassified to interest expense as interest payments are made on the related notes payable.

As of September 30, 2021, $15,535,000 remained in other comprehensive income (loss) related to NNN’s previously terminated interest rate hedges. During the nine months ended September 30, 2021 and 2020, NNN reclassified out of other comprehensive income (loss) $2,494,000 and $1,663,000, respectively, of which $565,000 and $642,000 was reclassified during the quarters ended September 30, 2021 and 2020, respectively, as an increase in interest expense. Over the next 12 months, NNN estimates that an additional $2,349,000 will be reclassified as an increase in interest expense from these terminated derivatives. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on NNN’s long-term debt.

NNN does not use derivatives for trading or speculative purposes or currently have any derivatives that are not designated as hedges. NNN had no derivative financial instruments outstanding at September 30, 2021.

21

Note 7 – Fair Value of Financial Instruments:

NNN believes the carrying value of its Credit Facility approximates fair value based upon its nature, terms and variable interest rate. NNN believes that the carrying value of its mortgages payable at September 30, 2021 and December 31, 2020, approximate fair value based upon current market prices of comparable instruments (Level 3). At September 30, 2021 and December 31, 2020, the fair value of NNN’s notes payable net of unamortized discount and excluding debt costs was $4,026,563,000 and $3,532,908,000, respectively, based upon quoted market prices, which is a Level 1 valuation since NNN's notes payable are publicly traded.

Note 8 – Subsequent Events:

NNN reviewed its subsequent events and transactions that have occurred after September 30, 2021, the date of the interim condensed consolidated balance sheet.

As of October 27, 2021, NNN had collected approximately 99% of rent originally due in the quarter ended September 30, 2021 and 99% of rent originally due in October 2021.

In September 2021, NNN announced the redemption of all outstanding depository shares representing interests in its 5.200% Series F Preferred Stock. The depository shares were redeemed on October 16, 2021 at $25.00 per depository share, plus all accrued and unpaid dividends through, but not including, the redemption date, for an aggregate redemption price of $25.111944 per depository share. For the quarter ending December 31, 2021, NNN will record a preferred stock redemption charge of $10,897,000, which is the excess carrying amount of the preferred stock redeemed over the cash paid to redeem the Series F Preferred Stock. On the redemption date, dividends on the depository shares representing interest in the Series F Preferred Stock ceased to accrue.

There were no other reportable subsequent events or transactions.

Overview

NNN, a Maryland corporation, is a fully integrated REIT formed in 1984. NNN's assets are primarily real estate assets. NNN acquires, owns, invests in and develops properties that are leased primarily to retail tenants under long-term net leases and are primarily held for investment ("Properties" or "Property Portfolio", or individually a "Property").

As of September 30, 2021, NNN owned 3,195 Properties, with an aggregate gross leasable area of approximately 33,005,000 square feet, located in 48 states, with a weighted average remaining lease term of 10.6 years. Approximately 99 percent of the Properties were leased as of September 30, 2021.

NNN’s management team focuses on certain key indicators to evaluate the financial condition and operating performance of NNN. The key indicators for NNN include items such as: the composition of the Property Portfolio (such as tenant, geographic and line of trade diversification), the occupancy rate of the Property Portfolio, certain financial performance ratios and profitability measures, industry trends and industry performance compared to that of NNN.

NNN evaluates the creditworthiness of its current and prospective tenants. This evaluation may include reviewing available financial statements, store level financial performance, press releases, public credit ratings from major credit rating agencies, industry news publications and financial market data (debt and equity pricing). NNN may also evaluate the business and operations of its tenants, including past payment history and periodically meeting with senior management of certain tenants.

NNN continues to maintain its diversification by tenant, geography and tenant's line of trade. NNN’s largest lines of trade concentrations are the convenience store and restaurant (including full and limited service) sectors. These sectors represent a large part of the freestanding retail property marketplace and NNN’s management believes these sectors present attractive investment opportunities. The Property Portfolio is geographically concentrated in the south and southeast United States, which are regions of historically above-average population growth. Given these concentrations, any financial hardship within these sectors or geographic regions could have a material adverse effect on the financial condition and operating performance of NNN.

24

Impact of COVID-19 on NNN’s Business

In 2020, the COVID-19 pandemic and the government reaction to it negatively affected almost every industry directly or indirectly. A number of NNN’s tenants experienced temporary closures of their operations and/or requested adjustments to their lease terms during this pandemic. As a result, these economic hardships have increased uncertainty with respect to the collectability of lease payments and have had a negative effect on NNN's financial results, including increased accounts receivables and related allowances and recognizing revenue on a cash basis from certain of its tenants.

During the quarter and nine months ended September 30, 2021, NNN and certain of NNN's tenants continue to be impacted by the COVID-19 pandemic which has resulted in the continued loss of revenue for certain tenants and challenged their ability to pay rent.

As of September 30, 2021, NNN has entered into rent deferral lease amendments with certain tenants, for an aggregate $4,758,000 and $52,019,000 of rent originally due for the years ending December 31, 2021 and 2020, respectively. The rent deferral lease amendments require the deferred rents to be repaid at a later time during the lease term. Approximately $3,259,000 of deferred rent was repaid in 2020 and approximately $6,068,000 and $27,087,000 of deferred rent was repaid during the quarter and nine months ended September 30, 2021, respectively. An additional $4,689,000 is due in 2021, with the remaining deferred rent coming due periodically by December 31, 2025.

The following table details the rental revenue for the quarter ended September 30, 2021 (collected as of October 27, 2021), as a percentage of annualized base rent, excluding the repayments of amounts previously deferred according to the rent deferral lease amendments:

	Lines of Trade	% of Total Annual Base Rent(1)			% of Rent Collected(2)
1.	Convenience stores		17.6	%		99.8	%
2.	Automotive service		12.1	%		99.7	%

17.	Home furnishings		1.5	%		100.0	%
18.	Travel plazas		1.5	%		100.0	%
19.	Drug stores		1.3	%		100.0	%
20.	Automobile auctions, wholesale		1.3	%		100.0	%
	Other		8.0	%		98.4	%
	Total		100.0	%		99.1	%

(1)	Based on annualized base rent for all leases in place as of September 30, 2021.
(2)	As of October 27, 2021, NNN has collected approximately 99% of rent originally due in October 2021.

Historical rent collections and rent relief requests may not be indicative of collections and requests in the future. Depending on macroeconomic conditions and their impact on a tenant's business and operations, deferred rents may be difficult to collect.

25

NNN will continue to monitor the impact of the economic downturn, among other things, when considering new property investments. As of September 30, 2021, NNN had $543,526,000 of cash and cash equivalents and $1,100,000,000 available for borrowings under its unsecured revolving credit facility (as the context requires, the previous and new revolving credit facility, the "Credit Facility"). NNN currently expects these combined resources, in addition to the cash provided by NNN's operations to be sufficient to meet NNN's demand for funds.

The rapid development and fluidity of the economic downturn precludes any prediction as to the ultimate adverse impact on the economy, retailing and NNN and will ultimately depend on future developments, none of which can be predicted with any certainty. Nevertheless, the economic downturn presents material uncertainty and risk with respect to NNN’s performance, business or financial condition, results of operations and cash flows.

NNN typically uses the proceeds from a Property disposition to either pay down the Credit Facility or reinvest in real estate.

Analysis of Revenue

General. During the quarter and nine months ended September 30, 2021, total revenues increased as compared to the same period in 2020, primarily due to a change in receivables reserves, scheduled rent increases based on increases in the Consumer Price Index ("CPI") and to the income generated from Properties acquired during the year ended December 31, 2020 and the nine months ended September 30, 2021 (See "Results of Operations - Property Analysis - Property Acquisitions").

The following table summarizes NNN’s revenues (dollars in thousands):

	Quarter Ended September 30,							Nine Months Ended September 30,

Quarter and Nine Months Ended September 30, 2021 versus Quarter and Nine Months Ended September 30, 2020

Rental Income. Rental income increased for the quarter and nine months ended September 30, 2021, as compared to the same period in 2020. The increase for the quarter and nine months ended September 30, 2021 is primarily due to a change in receivables reserves, scheduled rent increases based on increases in the CPI and Property acquisitions:

a partial year of Rental Revenue from 107 Properties with an aggregate gross leasable area of approximately 1,090,000 square feet during 2021, and

a full year of Rental Revenue from 63 Properties with aggregate gross leasable area of approximately 449,000 square feet in 2020.

Analysis of Expenses

General. Operating expenses increased for the quarter ended September 30, 2021, as compared to the same period in 2020, primarily due to the increase in general and administrative expenses which was partially offset by a decrease in impairment losses recognized on real estate. Operating expenses decreased for the nine months ended September 30, 2021, as compared to the same period in 2020, primarily due to the decrease in impairment losses recognized on real estate which was partially offset by an increase in general and administrative expenses and depreciation and amortization. The following table summarizes NNN’s expenses (dollars in thousands):

	Quarter Ended September 30,									Nine Months Ended September 30,
							Percent Increase									Percent Increase
	2021			2020			(Decrease)			2021			2020			(Decrease)

Quarter and Nine Months Ended September 30, 2021 versus Quarter and Nine Months Ended September 30, 2020

General and Administrative. General and administrative expenses increased in amount and as a percentage of total revenues for the quarter and nine months ended September 30, 2021, as compared to the same periods in 2020. The increase is primarily attributable to an increase in incentive compensation costs.

Impairment Losses – real estate, net of recoveries. NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, which provide for cash flows over this term. NNN generally intends to hold these assets for the long-term, therefore, a temporary change in cash flows due to COVID-19 alone would not be an indicator of impairment.

29

As a result of NNN's review of long-lived assets, including identifiable intangible assets, NNN recognized real estate impairments, net of recoveries as summarized in the table below (dollars in thousands):

	Quarter Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Total real estate impairments, net of recoveries	$	4,781	$	5,695	$	14,647	$	33,062
Number of Properties:
Vacant		5		1		19		10
Occupied		2		—		10		13

For the quarter and nine months ended September 30, 2021 and 2020, real estate impairments, net of recoveries, was less than one percent of NNN's total assets for the respective periods as reported on the Condensed Consolidated Balance Sheets. Due to NNN's core business of investing in real estate leased primarily to retail tenants under long-term net leases, the inherent risks of owning commercial real estate, and unknown potential changes in financial and economic conditions that may impact NNN's tenants, NNN believes it is reasonably possible to incur real estate impairment charges in the future.

Interest expense. Interest expense increased for the quarter and nine months ended September 30, 2021, as compared to the same periods in 2020. The following represents the primary changes in debt that have impacted interest expense (dollars in thousands):

Transaction	Effective Date	Principal			Stated Interest Rate			Original Maturity
Issuance 2030 Notes	March 2020	$	400,000			2.500	%	April 2030
Issuance 2050 Notes	March 2020		300,000			3.100	%	April 2050
Redemption 2022 Notes	March 2020		(325,000	)		3.800	%	October 2022
Issuance 2051 Notes	March 2021		450,000			3.500	%	April 2051
Redemption 2023 Notes	March 2021		(350,000	)		3.300	%	April 2023
Issuance 2052 Notes	September 2021		450,000			3.000	%	April 2052

In addition to the note payable transactions outlined in the table above, interest expense was impacted due to the Credit Facility having no weighted average outstanding balance for the nine months ended September 30, 2021 compared to a $25,239,000 weighted average outstanding balance with a weighted average interest rate of 2.6% for the nine months ended September 30, 2020. In addition, interest expense for the nine months ended September 30, 2021 and 2020 includes $2,078,000 and $2,291,000, respectively, in connection with the early redemption of the 2023 Notes and 2022 Notes, respectively.

Loss on Early Extinguishment of Debt. In March 2021, NNN redeemed the $350,000,000 3.300% notes payable that were due in April 2023. The notes were redeemed at a price equal to 100% of the principal amount, plus (i) a make-whole amount of $21,328,000 which is included in loss on early extinguishment of debt on the Condensed Consolidated Statement of Income and Comprehensive Income, and (ii) accrued and unpaid interest.

In March 2020, NNN redeemed the $325,000,000 3.800% notes payable that were due in October 2022. The notes were redeemed at a price equal to 100% of the principal amount, plus (i) a make-whole amount of $16,679,000 which is included in loss on early extinguishment of debt on the Condensed Consolidated Statement of Income and Comprehensive Income, and (ii) accrued and unpaid interest.

Liquidity

General. NNN’s demand for funds has been, and will continue to be, primarily for (i) payment of operating expenses and cash dividends; (ii) Property acquisitions and development; (iii) capital expenditures; (iv) payment of principal and interest on its outstanding indebtedness; and (v) other investments.

While the total impacts of the economic downturn are unknown, NNN expects to meet short-term liquidity requirements through cash and cash equivalents, cash provided from operations and NNN's Credit Facility. As of September 30, 2021, NNN has $543,526,000 of cash and cash equivalents and $1,100,000,000 available for borrowings under its Credit Facility.

NNN anticipates its long-term capital needs will be funded by the Credit Facility, cash provided from operations, the issuance of long-term debt or the issuance of common or preferred equity or other instruments convertible into or exchangeable for

30

common or preferred equity. However, there can be no assurance that additional financing or capital will be available, or that the terms will be acceptable or advantageous to NNN.

Cash and Cash Equivalents. NNN's cash and cash equivalents includes the aggregate of cash and cash equivalents and restricted cash and cash held in escrow from the Condensed Consolidated Balance Sheets. NNN did not have restricted cash or cash held in escrow as of September 30, 2021 and December 31, 2020. The table below summarizes NNN’s cash flows (dollars in thousands):

	Nine Months Ended September 30,
	2021			2020
Cash and cash equivalents:
Provided by operating activities	$	453,150		$	348,824
Used in investing activities		(384,156	)		(48,569	)
Provided by (used in) financing activities		207,296			(6,507	)
Increase		276,290			293,748
Net cash at beginning of period		267,236			1,112
Net cash at end of period	$	543,526		$	294,860

Cash provided by operating activities represents cash received primarily from Rental Revenue and interest income less cash used for general and administrative expenses. NNN’s cash flow from operating activities has been sufficient to pay the distributions for each period presented. The change in cash provided by operations for the quarters and nine months ended September 30, 2021 and 2020, is primarily the result of changes in revenues and expenses as discussed in “Results of Operations.” Cash generated from operations is expected to fluctuate in the future.

Changes in cash for investing activities are primarily attributable to the acquisitions and dispositions of Properties. NNN typically uses cash on hand or proceeds from its Credit Facility to fund the acquisition of its Properties.

NNN’s financing activities for the nine months ended September 30, 2021, included the following significant transactions:

(i) Issuance and redemption of notes payable resulted in the following:

•$436,417,000 in net proceeds from the issuance in March of the 3.500% notes payable due in April 2051;

•$350,000,000 payment in March for the early redemption of the 3.300% notes payable due in April 2023;

•$21,328,000 payment in March of the make-whole amount from the early redemption of the 3.300% notes payable due in April 2023; and

•$434,611,000 in net proceeds from the issuance in September of the 3.000% notes payable due in April 2052.

(ii) Issuance of common stock resulted in the following net proceeds:

•$1,061,000 from the issuance of 30,000 shares of common stock in connection with the at-the-market ("ATM") equity program; and

•$2,012,000 from the issuance of 46,666 shares of common stock in connection with the Dividend Reinvestment and Stock Purchase Plan ("DRIP").

(iii) Dividends paid:

•$274,550,000 to common stockholders; and

•$13,455,000 to holders of the depositary shares of NNN's 5.200% Series F Cumulative Redeemable Preferred Stock (the "Series F Preferred Stock").

Contractual Obligations and Commercial Commitments. The information in the following table summarizes NNN’s contractual obligations and commercial commitments outstanding as of September 30, 2021. The table presents principal cash flows by year-end of the expected maturity for debt obligations and commercial commitments outstanding as of September 30, 2021.

	Expected Maturity Date (dollars in thousands)

(2)	Interest calculation based on stated rate of the principal amount.
(3)	NNN is a lessee for its headquarters office lease.
(4)	NNN is a lessee for three ground lease arrangements.

In addition to the contractual obligations outlined above, NNN has committed to fund construction on 10 Properties. The improvements on such Properties are estimated to be completed within 12 months. These construction commitments, at September 30, 2021, are outlined in the table below (dollars in thousands):

Total commitment(1)	$	39,122
Less amount funded		17,395
Remaining commitment	$	21,727

(1) Includes land, construction costs, tenant improvements, lease costs and capitalized interest.

As of September 30, 2021, NNN did not have any other material contractual cash obligations, such as purchase obligations, financing lease obligations or other long-term liabilities other than those reflected in the tables above and previously disclosed under Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations included in NNN's Annual Report on Form 10-K for the year ended December 31, 2020. In addition to items reflected in the tables, in October 2021, NNN redeemed all of its 13,800,000 outstanding depositary shares, each representing a 1/100th interest in a share of its Series F Preferred Stock. Additional disclosure is included in Note 8 - Subsequent Events.

Management anticipates satisfying these obligations with a combination of NNN’s cash provided from operations, current capital resources on hand, its Credit Facility, debt or equity financings and asset dispositions.

Generally, the Properties are leased under long-term triple net leases, which require the tenant to pay all property taxes and assessments, to maintain the interior and exterior of the property, and to carry property and liability insurance coverage. Therefore, management anticipates that capital demands to meet obligations with respect to these Properties will be modest for the foreseeable future and can be met with funds from operations and working capital. Certain Properties are subject to leases under which NNN retains responsibility for specific costs and expenses associated with the Property. Management anticipates that the costs associated with these Properties, NNN's vacant Properties or those Properties that become vacant will also be met with funds from operations and working capital. NNN may be required to borrow under its Credit Facility or use other sources of capital in the event of significant capital expenditures or major repairs.

The lost revenues and increased property expenses resulting from vacant Properties or the inability to collect lease revenues could have a material adverse effect on the liquidity and results of operations if NNN is unable to re-lease the Properties at comparable rental rates and in a timely manner. NNN currently expects a short-term decrease in cash from operations as its tenants are impacted by the pandemic and, while contractually obligated, some have not paid all rent amounts due (See "Impact of COVID-19 on NNN's Business").

As of September 30, 2021, NNN owned 46 vacant, un-leased Properties which accounted for approximately one percent of total Properties held in the Property Portfolio.

Additionally, as of October 27, 2021, NNN had no tenants currently in bankruptcy under Chapter 11 of the U.S. Bankruptcy Code.

32

NNN generally monitors the financial performance of its significant tenants on an ongoing basis.

A prolonged continuation of business closures, reduced capacity at businesses or other social-distancing practices as a result of COVID-19 may adversely impact NNN's tenants’ ability to generate sufficient revenues to meet financial obligations, and could force tenants to default on their leases, or result in the bankruptcy of tenants, which would diminish the Rental Revenue NNN receives under its leases. Additionally, an increase in the number of vacant properties would increase NNN's real estate expenses, including expenses associated with ongoing maintenance and repairs, utilities, property taxes, and property and liability insurance. The ongoing development and fluidity of the pandemic precludes any prediction as to the ultimate adverse impact on NNN (See “Impact of COVID-19 on NNN’s Business”).

Dividends. NNN has made an election to be taxed as a REIT under Sections 856 through 860 of the Code, as amended, and related regulations and intends to continue to operate so as to remain qualified as a REIT for federal income tax purposes. NNN generally will not be subject to federal income tax on income that it distributes to its stockholders, provided that it distributes 100 percent of its REIT taxable income and meets certain other requirements for qualifying as a REIT. If NNN fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four years following the year during which qualification is lost. Such an event could materially adversely affect NNN’s income and ability to pay dividends. NNN believes it has been structured as, and its past and present operations qualify NNN as, a REIT.

One of NNN’s primary objectives, consistent with its policy of retaining sufficient cash for reserves and working capital purposes and maintaining its status as a REIT, is to distribute a substantial portion of its funds available from operations to its stockholders in the form of dividends.

The following table outlines the dividends declared and paid for each issuance of NNN's stock (dollars in thousands, except per share data):

	Quarter Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Series F preferred stock(1):
Dividends	$	4,485	$	4,485	$	13,455	$	13,455
Per depositary share		0.3250		0.3250		0.9750		0.9750
Common stock:
Dividends		92,731		89,947		274,550		266,365
Per share		0.5300		0.5200		1.5700		1.5500

(1) In September 2021, NNN called for the redemption of all outstanding shares of its 5.200% Series F Preferred Stock, including all accrued and unpaid dividends through, but not including, the redemption date, on October 16, 2021.

In October 2021, NNN declared a dividend of $0.5300 per share which is payable in November 2021 to its common stockholders of record as of October 29, 2021.

33

Capital Resources

Generally, cash needs for Property acquisitions, debt payments, capital expenditures, development and other investments have been funded by equity and debt offerings, bank borrowings, the sale of Properties and, to a lesser extent, by internally generated funds. Cash needs for operating and interest expenses and dividends have generally been funded by internally generated funds. If available, future sources of capital include proceeds from the public or private offering of NNN’s debt or equity securities, secured or unsecured borrowings from banks or other lenders, proceeds from the sale of Properties, as well as undistributed funds from operations.

Debt

NNN expects to use debt primarily for property acquisitions and development of single-tenant retail properties, either directly or through investment interests. Additionally, debt may be used to refinance existing debt. The following is a summary of NNN’s total outstanding debt as of (dollars in thousands):

	September 30, 2021		Percentage of Total			December 31, 2020		Percentage of Total
Mortgages payable	$	10,875		0.3	%	$	11,395		0.4	%
Notes payable		3,734,764		99.7	%		3,209,527		99.6	%
Total outstanding debt	$	3,745,639		100.0	%	$	3,220,922		100.0	%

Line of Credit Payable. In June 2021, NNN amended and restated its credit agreement to increase the borrowing capacity under its Credit Facility from $900,000,000 to $1,100,000,000 and amended certain other terms under the former revolving Credit Facility. The Credit Facility had no weighted average outstanding balance during the nine months ended September 30, 2021. The Credit Facility matures June 2025, unless the Company exercises its options to extend maturity to June 2026. The Credit Facility bears interest at LIBOR plus 77.5 basis points; however, such interest rate may change pursuant to a tiered interest rate structure based on NNN's debt rating. Additionally, as part of NNN's environmental, social and governance ("ESG") initiative, pricing may be reduced if specified ESG metrics are achieved. The Credit Facility also includes an accordion feature which permits NNN to increase the facility size up to $2,000,000,000, subject to lender approval. In connection with the Credit Facility, NNN incurred loan costs of $7,439,000 which are included in debt costs on the Condensed Consolidated Balance Sheet. As of September 30, 2021, there was no outstanding balance and $1,100,000,000 was available for future borrowings under the Credit Facility, and NNN was in compliance with each of the financial covenants.

Notes Payable. In 2021, NNN filed prospectus supplements to the prospectus contained in its August 2020 shelf registration statement and issued $450,000,000 aggregate principal amount of 3.500% notes due April 2051 (the “2051 Notes”) and $450,000,000 aggregate principal amount of 3.000% notes due April 2052 (the "2052 Notes" and, together with the 2051 Notes, the "Notes"). Each note issuance is summarized in the table below (dollar in thousands):

Notes	Issue Date	Principal		Discount (1)		Net Price		Stated Rate			Effective Rate (2)			Maturity Date
2051 Notes (3)	March 2021	$	450,000	$	8,406	$	441,594		3.500	%		3.602	%	April 2051
2052 Notes (4)(5)	September 2021		450,000		10,422		439,578		3.000	%		3.118	%	April 2052

(1)	The note discounts are amortized to interest expense over the respective term of each debt obligation using the effective interest method.
(2)	Includes the effects of the discount at issuance.
(3)	NNN used the net proceeds from the issuance of the 2051 Notes to redeem all of its 3.300% notes payable that were due 2023, fund future property acquisitions and for general corporate purposes.
(4)	In October 2021, NNN used the net proceeds from the issuance of the 2052 Notes to redeem all of its 13,800,000 outstanding depositary shares, each representing a 1/100th interest in a share of its Series F Preferred Stock. Additional disclosure is included in Note 8 – Subsequent Events. In addition, we intend to use the remainder of the net proceeds from this offering to fund future property acquisitions and for general corporate purposes.
(5)	NNN entered into forward swaps which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt. Upon the issuance of the 2052 Notes, NNN terminated such derivatives, and the resulting fair value was deferred in accumulated other comprehensive income (loss) and is being amortized over the term of the respective notes using the effective interest method. Additional disclosure is included in Note 6 – Derivatives.

Each series of Notes is senior, unsecured obligations of NNN and is subordinated to all secured debt of NNN and to the debt and other liabilities of NNN's subsidiaries. Each of the Notes is redeemable at NNN's option, at any time, in whole or in part, at a redemption price equal to (i) the sum of the outstanding principal amount of the notes being redeemed plus accrued interest

34

thereon, but not including the redemption date, and (ii) the make-whole amount, if any, as defined in the applicable supplemental indenture related to the notes.

In connection with the Notes, NNN incurred debt issuance costs totaling $10,144,000 consisting primarily of underwriting discounts and commissions, legal and accounting fees, rating agency fees and printing expenses. Debt issuance costs for all note issuances have been deferred and presented as a reduction to notes payable and are being amortized over the term of the respective notes using the effective interest method.

In March 2021, NNN redeemed the $350,000,000 3.300% notes payable that were due in April 2023. The notes were redeemed at a price equal to 100% of the principal amount, plus (i) a make-whole amount of $21,328,000 which is included in loss on early extinguishment of debt on the Condensed Consolidated Statement of Income and Comprehensive Income, and (ii) accrued and unpaid interest.

Debt and Equity Securities

NNN has used, and expects to use in the future, issuances of debt and equity securities primarily to pay down its outstanding debt and to finance acquisitions.

Securities Offerings. In August 2020, NNN filed a shelf registration statement with the Securities and Exchange Commission (the "Commission") which was automatically effective and permits the issuance by NNN of an indeterminate amount of debt and equity securities.

Information related to NNN's publicly held debt and equity securities is included in NNN's Annual Report on Form 10-K for the year ended December 31, 2020.

At-The-Market Offerings. Under NNN's shelf registration statement, NNN established an ATM equity program which allows NNN to sell shares of common stock from time to time. The following outlines NNN's ATM programs:

	2020 ATM	2018 ATM

Item 3. Quantitative and Qualitative Disclosures About Market Risk

NNN is exposed to interest rate risk primarily as a result of its variable rate Credit Facility and its fixed rate debt which is used to finance NNN’s development and acquisition activities, as well as for general corporate purposes. NNN’s interest rate risk management objective is to limit the impact of interest rate changes on earnings and cash flows and to reduce overall borrowing costs. To achieve its objectives, NNN borrows at both fixed and variable rates on its long-term debt. As of September 30, 2021, NNN had no outstanding derivatives.

The information in the table below summarizes NNN’s market risks associated with its debt obligations outstanding as of September 30, 2021 and December 31, 2020. The table presents principal payments and related interest rates by year for debt obligations outstanding as of September 30, 2021. NNN has a variable interest rate risk on its Credit Facility which had no outstanding balance as of September 30, 2021 and December 31, 2020. The weighted average interest rate for the Credit Facility for year ended December 31, 2020 was 2.6%. The table incorporates only those debt obligations that existed as of September 30, 2021, and it does not consider those debt obligations or positions which could arise after this date and therefore has limited predictive value. As a result, NNN’s ultimate realized gain or loss with respect to interest rate fluctuations will depend on the exposures that arise during the period, NNN’s hedging strategies at that time and interest rates. If interest rates on NNN's variable rate debt increased by one percent, NNN's interest expense would remain unchanged for the nine months ended September 30, 2021.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles. The unaudited condensed consolidated financial statements reflect all adjustments (including normal recurring accruals) which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Operating results for the quarter and nine months ended September 30, 2021, may not be indicative of the results that may be expected for the year ending December 31, 2021. See "Note 8 – Subsequent Events." Amounts as of December 31, 2020, included in the condensed consolidated financial statements have been derived from the audited consolidated financial statements as of that date. The unaudited condensed consolidated financial statements, included herein, should be read in conjunction with the consolidated financial statements and notes thereto as well as Management's Discussion and Analysis of Financial Condition and Results of Operations in NNN's Form 10-K for the year ended December 31, 2020.

COVID-19 Pandemic – During the quarter and nine months ended September 30, 2021, NNN and its tenants continue to be impacted by the novel strain of coronavirus ("COVID-19") pandemic which has resulted in the loss of revenue for certain tenants and challenged their ability to pay rent. NNN has entered into rent deferral lease amendments with certain tenants (See Note 2).

Principles of Consolidation – NNN’s condensed consolidated financial statements include the accounts of each of the respective majority owned and controlled affiliates, including transactions whereby NNN has been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codifications ("ASC") guidance included in Consolidation. All significant intercompany account balances and transactions have been eliminated.

Real Estate Portfolio – NNN records the acquisition of real estate at cost, including acquisition and closing costs. The cost of Properties developed or funded by NNN includes direct and indirect costs of construction, property taxes, interest and other miscellaneous costs incurred during the development period until the project is substantially complete and available for occupancy. NNN recorded $215,000 and $1,218,000 in capitalized interest during the development period for the nine months ended September 30, 2021 and 2020, respectively, of which $87,000 and $332,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Purchase Accounting for Acquisition of Real Estate Subject to a Lease – In accordance with the FASB guidance on business combinations, consideration for the real estate acquired is allocated to the acquired tangible assets, consisting of land, building and tenant improvements, and, if applicable, to identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, as applicable, based on their respective fair values.

The fair value estimate is sensitive to significant assumptions, such as establishing a range of relevant market assumptions for land, building and rent and where the acquired property falls within that range. These market assumptions for land, building

and rent use the most relevant comparable properties for an acquisition. The final range relies upon ranking comparable properties' attributes from most to least similar.

The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, and the "as-if-vacant" value is then allocated to land, building and tenant improvements based on the determination of their fair values.

In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded as other assets or liabilities based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining term of the lease and the renewal option terms if it is probable that the tenant will exercise options. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining terms of the respective leases. The capitalized below-market lease values are amortized as an increase to rental income over the initial term unless the Company believes that it is likely that the tenant will renew the lease for an option term whereby the Company amortizes the value attributable to the renewal over the renewal period.

The aggregate value of other acquired intangible assets, consisting of in-place leases, is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates over (ii) the estimated fair value of the property as-if-vacant, determined as set forth above. The value of in-place leases exclusive of the value of above-market and below-market in-place leases is amortized to expense over the remaining non-cancelable periods of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off in that period. The value of tenant relationships is reviewed on individual transactions to determine if future value was derived from the acquisition.

Lease Accounting – In accordance with FASB Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," ("ASC 842"), NNN recorded Right-Of-Use assets and operating lease liabilities as lessee under operating leases.

In July 2021, the FASB issued ASU 2021-05, which affects lessors with lease contracts that (i) have variable lease payments that do not depend on a reference index or a rate and (ii) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. NNN has reviewed all existing leases and determined this update has no effect on the current portfolio, but will apply ASU 2021-05 prospectively to leases that commence or are modified in the future.

In April 2020, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. NNN elected to make this policy election for COVID-19 lease concessions, including the rent deferral lease amendments effective during the year ended December 31, 2020 and the quarter and nine months ended September 30, 2021.

In accordance with ASC 842, NNN reviews the collectability of its lease payments on an ongoing basis. NNN considers collectability indicators when analyzing accounts receivable (and accrued rent) and historical bad debt levels, tenant credit-worthiness and current economic trends, all of which assists in evaluating the probability of outstanding and future lease payment collections. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition bankruptcy claims. At the point NNN deems the collection of lease payments not probable, previously recognized rental revenue and any related accrued rent are reversed and, subsequently, any lease revenue is only recognized when cash receipts are received. As a result of the review of lease payments collectability, no outstanding receivables and related accrued rent were written off during the quarter and nine months ended September 30, 2021, and no tenants were reclassified as cash basis for accounting purposes.

NNN includes an allowance for doubtful accounts in rental income on the Consolidated Statements of Income and Comprehensive Income.

As of September 30, 2021, approximately six percent of total Properties, and approximately seven percent of aggregate gross leasable area held in the Property Portfolio, was leased to 11 tenants that NNN has determined to recognize revenue on a cash basis. During the nine months ended September 30, 2021 and 2020, NNN recognized $37,999,000 and $930,000, respectively, of rental income from certain tenants for periods following their classification to cash basis for accounting, of which $13,630,000 and $726,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Impairment – Real Estate – NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are

currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, which provide for cash flows over this term. NNN generally intends to hold these assets for the long-term, therefore, a temporary change in cash flows due to COVID-19 alone would not be an indicator of impairment.

Credit Losses on Financial Instruments – FASB ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” (“ASC 326”) requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings. The guidance requires a lifetime credit loss expected at inception and requires pooling of assets, which share similar risk characteristics. NNN is required to evaluate current economic conditions, as well as, make future expectations of economic conditions. In addition, the measurement of the expected credit loss is over the asset’s contractual term.

As of September 30, 2021 and December 31, 2020, NNN had mortgages receivable of $2,117,000 and $2,482,000, respectively, included in other assets on the Condensed Consolidated Balance Sheets, net of $135,000 and $158,000 allowance for credit loss, respectively. NNN measures the allowance for credit loss based on the fair value of the collateral and the historical collectability trend analysis over 15 years.

Debt Costs – Line of Credit Payable – Debt costs incurred in connection with NNN's $1,100,000,000 line of credit have been deferred and are being amortized to interest expense over the term of the loan commitment using the straight-line method, which approximates the effective interest method. NNN has recorded debt costs associated with the line of credit as an asset, in debt costs on the Condensed Consolidated Balance Sheets.

Debt Costs – Notes Payable – Debt costs incurred in connection with the issuance of NNN’s notes payable have been deferred and are being amortized to interest expense over the term of the respective debt obligation using the effective interest method. These costs of $38,145,000 and $31,140,000, as of September 30, 2021 and December 31, 2020, respectively, are included in notes payable on the Condensed Consolidated Balance Sheets net of accumulated amortization of $8,670,000 and $9,317,000, respectively.

Earnings Per Share – Earnings per share have been computed pursuant to the FASB guidance included in Earnings Per Share. The guidance requires classification of the Company’s unvested restricted share units, which carry rights to receive nonforfeitable dividends, as participating securities requiring the two-class method of computing earnings per share. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period.

The following table is a reconciliation of the numerator and denominator used in the computation of basic and diluted earnings per common share using the two-class method (dollars in thousands):

	Quarter Ended September 30,						Nine Months Ended September 30,

Fair Value Measurement – NNN’s estimates of fair value of financial and non-financial assets and liabilities are based on the framework established in the fair value accounting guidance. The framework specifies a hierarchy of valuation inputs which was established to increase consistency, clarity and comparability in fair value measurements and related disclosures. The guidance describes a fair value hierarchy based upon three levels of inputs that may be used to measure fair value, two of which are considered observable and one that is considered unobservable. The following describes the three levels:

•Level 1 – Valuation is based upon quoted prices in active markets for identical assets or liabilities.

•Level 2 – Valuation is based upon inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 – Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include option pricing models, discounted cash flow models and similar techniques.

Accumulated Other Comprehensive Income (Loss) – The following table outlines the changes in accumulated other comprehensive income (loss) for the nine months ended September 30, 2021, (dollars in thousands):

	Gain (Loss) on Cash Flow Hedges(1)
Beginning balance, December 31, 2020	$	(16,445	)

Reclassifications from accumulated other comprehensive income to net earnings		2,494		(2)

(1)	Additional disclosure is included in Note 6 – Derivatives.
(2)	Recorded in interest expense on the Condensed Consolidated Statements of Income and Comprehensive Income.

Use of Estimates – Additional critical accounting policies of NNN include management’s estimates and assumptions relating to the reporting of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities and are required to prepare the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Significant accounting policies include management’s estimates of the useful lives used in calculating depreciation expense relating to real estate asset purchase accounting for acquisition of real estate subject to a lease, the recoverability of the carrying value of long-lived assets and management's evaluation of the probability of outstanding and future lease payment collections. Actual results could differ from those estimates.

Note 2 – Real Estate:

Real Estate – Portfolio

Leases – At September 30, 2021, NNN’s real estate portfolio had a weighted average remaining lease term of 10.6 years and consisted of 3,187 leases classified as operating leases and an additional six leases accounted for as direct financing.

The following is a summary of the general structure of the leases in the Property Portfolio, although the specific terms of each lease can vary significantly. Generally, the Property leases provide for initial terms of 10 to 20 years. The Properties are generally leased under net leases, pursuant to which the tenant typically bears responsibility for substantially all property costs and expenses associated with ongoing maintenance, repair, replacement and operation of the property, including utilities, property taxes and property and liability insurance. Certain Properties are subject to leases under which NNN retains responsibility for specific costs and expenses of the Property. NNN's leases provide for annual base rental payments (generally payable in monthly installments), and generally provide for limited increases in rent as a result of (i) increases in the Consumer Price Index ("CPI"), (ii) fixed increases, or, to a lesser extent, (iii) increases in the tenant’s sales volume.

Generally, NNN's leases provide the tenant with one or more multi-year renewal options, subject to generally the same terms and conditions provided under the initial lease term, including rent increases. NNN’s lease term is based on the non-cancellable base term unless economic incentives make it reasonably certain that an option period to extend the lease will be exercised, in which event NNN includes the options. Some of the leases also provide that in the event NNN wishes to sell the Property subject to that lease, NNN first must offer the lessee the right to purchase the Property on the same terms and conditions as any offer which NNN intends to accept for the sale of the Property.

As of September 30, 2021, NNN has entered into rent deferral lease amendments with certain tenants, for an aggregate $4,758,000 and $52,019,000 of rent originally due for the years ending December 31, 2021 and 2020, respectively. The rent deferral lease amendments require the deferred rents to be repaid at a later time during the lease term. Approximately $3,259,000 of deferred rent was repaid in 2020 and approximately $6,068,000 and $27,087,000 of deferred rent was repaid during the quarter and nine months ended September 30, 2021, respectively. An additional $4,689,000 is due in 2021, with the remaining deferred rent coming due periodically by December 31, 2025.

Historical rent collections and rent relief requests may not be indicative of collections and requests in the future. Depending on macroeconomic conditions and their impact on a tenant's business and operations, deferred rents may be difficult to collect.

Total commitment(1)	$	39,122
Less amount funded		17,395
Remaining commitment	$	21,727

(1) Includes land, construction costs, tenant improvements, lease costs and capitalized interest.

Real Estate – Impairments

NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, which provide for cash flows over this term. NNN generally intends to hold these assets for the long-term, therefore, a temporary change in cash flows due to COVID-19 alone would not be an indicator of impairment.

As a result of NNN's review of long-lived assets, including identifiable intangible assets, NNN recognized real estate impairments, net of recoveries as summarized in the table below (dollars in thousands):

	Quarter Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Total real estate impairments, net of recoveries	$	4,781	$	5,695	$	14,647	$	33,062
Number of Properties:
Vacant		5		1		19		10
Occupied		2		—		10		13

The valuation of impaired assets is determined using widely accepted valuation techniques including discounted cash flow analysis, income capitalization, analysis of recent comparable sales transactions, actual sales negotiations and bona fide purchase offers received from third parties, which are Level 3 inputs. NNN may consider a single valuation technique or multiple valuation techniques, as appropriate, when estimating the fair value of its real estate.

Line of Credit Payable

Note 3 – Line of Credit Payable:

In June 2021, NNN amended and restated its credit agreement to increase the borrowing capacity under its unsecured revolving credit facility from $900,000,000 to $1,100,000,000 and amended certain other terms under the former revolving credit facility (as the context requires, the previous and new revolving credit facility, the "Credit Facility"). The Credit Facility had no weighted average outstanding balance during the nine months ended September 30, 2021. The Credit Facility matures in June 2025, unless the Company exercises its options to extend maturity to June 2026. The Credit Facility bears interest at LIBOR plus 77.5 basis points; however, such interest rate may change pursuant to a tiered interest rate structure based on NNN's debt rating. Additionally, as part of NNN's environmental, social and governance ("ESG") initiative, pricing may be reduced if specified ESG metrics are achieved. The Credit Facility also includes an accordion feature which permits NNN to increase the facility size up to $2,000,000,000, subject to lender approval. In connection with the Credit Facility, NNN incurred loan costs of $7,439,000 which are included in debt costs on the Condensed Consolidated Balance Sheet. As of September 30, 2021, there was no outstanding balance and $1,100,000,000 was available for future borrowings under the Credit Facility, and NNN was in compliance with each of the financial covenants.

(1)	The note discounts are amortized to interest expense over the respective term of each debt obligation using the effective interest method.
(2)	Includes the effects of the discount at issuance.
(3)	NNN entered into forward swaps which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt. Upon the issuance of the 2052 Notes, NNN terminated such derivatives, and the resulting fair value was deferred in accumulated other comprehensive income (loss) and is being amortized over the term of the respective notes using the effective interest method. Additional disclosure is included in Note 6 – Derivatives.

Each series of Notes is a senior unsecured obligation of NNN and is subordinated to all secured debt of NNN and to the debt and other liabilities of NNN's subsidiaries. Each series of Notes is redeemable at NNN's option, at any time, in whole or in part, at a redemption price equal to (i) the sum of the outstanding principal amount of the notes being redeemed plus accrued interest thereon, up to but not including the redemption date, and (ii) the make-whole amount, if any, as defined in the applicable supplemental indenture related to the notes.

In connection with the Notes, NNN incurred debt issuance costs totaling $10,144,000 consisting primarily of underwriting discounts and commissions, legal and accounting fees, rating agency fees and printing expenses. Debt issuance costs for all note issuances have been deferred and presented as a reduction to notes payable and are being amortized over the term of the respective notes using the effective interest method.

In March 2021, NNN redeemed the $350,000,000 3.300% notes payable that were due in April 2023. The notes were redeemed at a price equal to 100% of the principal amount, plus (i) a make-whole amount of $21,328,000 which is included in loss on early extinguishment of debt on the Condensed Consolidated Statement of Income and Comprehensive Income, and (ii) accrued and unpaid interest.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Note 6 – Derivatives:

In accordance with the guidance on derivatives and hedging, NNN records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or a firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

NNN’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements or other identified risks. To accomplish this objective, NNN primarily uses treasury locks, forward starting swaps and interest rate swaps as part of its cash flow hedging strategy. Treasury locks and forward starting swaps are used to hedge forecasted debt issuances. Treasury locks designated as cash flow hedges lock in the yield/price of a treasury security. Forward starting swaps also lock the associated swap spread. Interest rate swaps designated as cash flow hedges are used to hedge the variable cash flows associated with floating rate debt and involve the receipt or payment of variable rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount.

For derivatives designated as cash flow hedges, the change in the fair value of the derivative is initially reported in other comprehensive income (loss) (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings.

NNN discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated or exercised, the derivative is re-designated as a hedging instrument or management determines that designation of the derivative as a hedging instrument is no longer appropriate.

When hedge accounting is discontinued, NNN recognizes any changes in its fair value in earnings and continues to carry the derivative on the balance sheet or may choose to settle the derivative at that time with a cash payment or receipt. NNN records a cash settlement of forward starting swaps in the Condensed Consolidated Statements of Cash Flows as an operating activity.

The following table outlines NNN's terminated derivatives which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt (dollars in thousands):

Notes Payable	Terminated	Description	Aggregate Notional Amount		Liability (Asset) Fair Value When Terminated			Fair Value Deferred In Other Comprehensive Income (1)
2024	May 2014	Three forward starting swaps	$	225,000	$	6,312		$	6,312
2025	October 2015	Four forward starting swaps		300,000		13,369			13,369

2052	September 2021	Two forward starting swaps		120,000		1,584			1,584

(1) The amount reported in accumulated other comprehensive income (loss) will be reclassified to interest expense as interest payments are made on the related notes payable.

As of September 30, 2021, $15,535,000 remained in other comprehensive income (loss) related to NNN’s previously terminated interest rate hedges. During the nine months ended September 30, 2021 and 2020, NNN reclassified out of other comprehensive income (loss) $2,494,000 and $1,663,000, respectively, of which $565,000 and $642,000 was reclassified during the quarters ended September 30, 2021 and 2020, respectively, as an increase in interest expense. Over the next 12 months, NNN estimates that an additional $2,349,000 will be reclassified as an increase in interest expense from these terminated derivatives. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on NNN’s long-term debt.

NNN does not use derivatives for trading or speculative purposes or currently have any derivatives that are not designated as hedges. NNN had no derivative financial instruments outstanding at September 30, 2021.

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation – NNN’s condensed consolidated financial statements include the accounts of each of the respective majority owned and controlled affiliates, including transactions whereby NNN has been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codifications ("ASC") guidance included in Consolidation. All significant intercompany account balances and transactions have been eliminated.

Real Estate Portfolio and Impairment

Real Estate Portfolio – NNN records the acquisition of real estate at cost, including acquisition and closing costs. The cost of Properties developed or funded by NNN includes direct and indirect costs of construction, property taxes, interest and other miscellaneous costs incurred during the development period until the project is substantially complete and available for occupancy. NNN recorded $215,000 and $1,218,000 in capitalized interest during the development period for the nine months ended September 30, 2021 and 2020, respectively, of which $87,000 and $332,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Purchase Accounting for Acquisition of Real Estate Subject to a Lease – In accordance with the FASB guidance on business combinations, consideration for the real estate acquired is allocated to the acquired tangible assets, consisting of land, building and tenant improvements, and, if applicable, to identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, as applicable, based on their respective fair values.

The fair value estimate is sensitive to significant assumptions, such as establishing a range of relevant market assumptions for land, building and rent and where the acquired property falls within that range. These market assumptions for land, building

and rent use the most relevant comparable properties for an acquisition. The final range relies upon ranking comparable properties' attributes from most to least similar.

The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, and the "as-if-vacant" value is then allocated to land, building and tenant improvements based on the determination of their fair values.

In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded as other assets or liabilities based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining term of the lease and the renewal option terms if it is probable that the tenant will exercise options. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining terms of the respective leases. The capitalized below-market lease values are amortized as an increase to rental income over the initial term unless the Company believes that it is likely that the tenant will renew the lease for an option term whereby the Company amortizes the value attributable to the renewal over the renewal period.

The aggregate value of other acquired intangible assets, consisting of in-place leases, is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates over (ii) the estimated fair value of the property as-if-vacant, determined as set forth above. The value of in-place leases exclusive of the value of above-market and below-market in-place leases is amortized to expense over the remaining non-cancelable periods of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off in that period. The value of tenant relationships is reviewed on individual transactions to determine if future value was derived from the acquisition.

Impairment – Real Estate – NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are

currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, which provide for cash flows over this term. NNN generally intends to hold these assets for the long-term, therefore, a temporary change in cash flows due to COVID-19 alone would not be an indicator of impairment.

Lease Accounting – In accordance with FASB Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," ("ASC 842"), NNN recorded Right-Of-Use assets and operating lease liabilities as lessee under operating leases.

In July 2021, the FASB issued ASU 2021-05, which affects lessors with lease contracts that (i) have variable lease payments that do not depend on a reference index or a rate and (ii) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. NNN has reviewed all existing leases and determined this update has no effect on the current portfolio, but will apply ASU 2021-05 prospectively to leases that commence or are modified in the future.

In April 2020, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. NNN elected to make this policy election for COVID-19 lease concessions, including the rent deferral lease amendments effective during the year ended December 31, 2020 and the quarter and nine months ended September 30, 2021.

In accordance with ASC 842, NNN reviews the collectability of its lease payments on an ongoing basis. NNN considers collectability indicators when analyzing accounts receivable (and accrued rent) and historical bad debt levels, tenant credit-worthiness and current economic trends, all of which assists in evaluating the probability of outstanding and future lease payment collections. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition bankruptcy claims. At the point NNN deems the collection of lease payments not probable, previously recognized rental revenue and any related accrued rent are reversed and, subsequently, any lease revenue is only recognized when cash receipts are received. As a result of the review of lease payments collectability, no outstanding receivables and related accrued rent were written off during the quarter and nine months ended September 30, 2021, and no tenants were reclassified as cash basis for accounting purposes.

NNN includes an allowance for doubtful accounts in rental income on the Consolidated Statements of Income and Comprehensive Income.

As of September 30, 2021, approximately six percent of total Properties, and approximately seven percent of aggregate gross leasable area held in the Property Portfolio, was leased to 11 tenants that NNN has determined to recognize revenue on a cash basis. During the nine months ended September 30, 2021 and 2020, NNN recognized $37,999,000 and $930,000, respectively, of rental income from certain tenants for periods following their classification to cash basis for accounting, of which $13,630,000 and $726,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively.

Lease Accounting, Lessee

Lease Accounting – In accordance with FASB Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," ("ASC 842"), NNN recorded Right-Of-Use assets and operating lease liabilities as lessee under operating leases.

In July 2021, the FASB issued ASU 2021-05, which affects lessors with lease contracts that (i) have variable lease payments that do not depend on a reference index or a rate and (ii) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing.

In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. NNN elected to make this policy election for COVID-19 lease concessions, including the rent deferral lease amendments effective during the year ended December 31, 2020 and the quarter and nine months ended September 30, 2021.

In accordance with ASC 842, NNN reviews the collectability of its lease payments on an ongoing basis. NNN considers collectability indicators when analyzing accounts receivable (and accrued rent) and historical bad debt levels, tenant credit-worthiness and current economic trends, all of which assists in evaluating the probability of outstanding and future lease payment collections. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition bankruptcy claims.

As a result of the review of lease payments collectability, no outstanding receivables and related accrued rent were written off during the quarter and nine months ended September 30, 2021, and no tenants were reclassified as cash basis for accounting purposes.

NNN includes an allowance for doubtful accounts in rental income on the Consolidated Statements of Income and Comprehensive Income.

As of September 30, 2021, approximately six percent of total Properties, and approximately seven percent of aggregate gross leasable area held in the Property Portfolio, was leased to 11 tenants that NNN has determined to recognize revenue on a cash basis. During the nine months ended September 30, 2021 and 2020, NNN recognized $37,999,000 and $930,000, respectively, of rental income from certain tenants for periods following their classification to cash basis for accounting, of which $13,630,000 and $726,000 was recorded during the quarters ended September 30, 2021 and 2020, respectively

Credit Losses on Financial Instruments

Credit Losses on Financial Instruments – FASB ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” (“ASC 326”) requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings. The guidance requires a lifetime credit loss expected at inception and requires pooling of assets, which share similar risk characteristics. NNN is required to evaluate current economic conditions, as well as, make future expectations of economic conditions. In addition, the measurement of the expected credit loss is over the asset’s contractual term.

As of September 30, 2021 and December 31, 2020, NNN had mortgages receivable of $2,117,000 and $2,482,000, respectively, included in other assets on the Condensed Consolidated Balance Sheets, net of $135,000 and $158,000 allowance for credit loss, respectively. NNN measures the allowance for credit loss based on the fair value of the collateral and the historical collectability trend analysis over 15 years.

Debt Costs

Debt Costs – Line of Credit Payable – Debt costs incurred in connection with NNN's $1,100,000,000 line of credit have been deferred and are being amortized to interest expense over the term of the loan commitment using the straight-line method, which approximates the effective interest method. NNN has recorded debt costs associated with the line of credit as an asset, in debt costs on the Condensed Consolidated Balance Sheets.

Debt Costs – Notes Payable – Debt costs incurred in connection with the issuance of NNN’s notes payable have been deferred and are being amortized to interest expense over the term of the respective debt obligation using the effective interest method. These costs of $38,145,000 and $31,140,000, as of September 30, 2021 and December 31, 2020, respectively, are included in notes payable on the Condensed Consolidated Balance Sheets net of accumulated amortization of $8,670,000 and $9,317,000, respectively.

Earnings Per Share

Earnings Per Share – Earnings per share have been computed pursuant to the FASB guidance included in Earnings Per Share. The guidance requires classification of the Company’s unvested restricted share units, which carry rights to receive nonforfeitable dividends, as participating securities requiring the two-class method of computing earnings per share. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period.

Fair Value Measurement

Fair Value Measurement – NNN’s estimates of fair value of financial and non-financial assets and liabilities are based on the framework established in the fair value accounting guidance. The framework specifies a hierarchy of valuation inputs which was established to increase consistency, clarity and comparability in fair value measurements and related disclosures. The guidance describes a fair value hierarchy based upon three levels of inputs that may be used to measure fair value, two of which are considered observable and one that is considered unobservable. The following describes the three levels:

•Level 1 – Valuation is based upon quoted prices in active markets for identical assets or liabilities.

•Level 2 – Valuation is based upon inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 – Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include option pricing models, discounted cash flow models and similar techniques.

Use of Estimates

Use of Estimates – Additional critical accounting policies of NNN include management’s estimates and assumptions relating to the reporting of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities and are required to prepare the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Significant accounting policies include management’s estimates of the useful lives used in calculating depreciation expense relating to real estate asset purchase accounting for acquisition of real estate subject to a lease, the recoverability of the carrying value of long-lived assets and management's evaluation of the probability of outstanding and future lease payment collections. Actual results could differ from those estimates.

[1] The note discounts are amortized to interest expense over the respective term of each debt obligation using the effective interest method.

[2] Includes the effects of the discount at issuance.

[3] NNN entered into forward swaps which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt. Upon the issuance of the 2052 Notes, NNN terminated such derivatives, and the resulting fair value was deferred in accumulated other comprehensive income (loss) and is being amortized over the term of the respective notes using the effective interest method.
