Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Principles of Consolidation | Principles of Consolidation. NNN's 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 FASB ASC guidance included in Topic 810, Consolidation. All significant intercompany account balances and transactions have been eliminated.
Real Estate Portfolio | 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, third-party costs and other miscellaneous costs incurred during the development period until the project is substantially completed and available for occupancy. For the years ended December 31, 2025, 2024 and 2023, NNN recorded $2,359,000, $5,805,000 and $4,286,000, respectively, in capitalized interest during the development period. Purchase Accounting for Acquisition of Real Estate. In accordance with the FASB ASC Topic 805, 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 in-place 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 value 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 valued by comparing the purchase price paid for a property after adjusting for existing in-place leases to the estimated fair value of the property as-if-vacant, determined as set forth above. This intangible asset 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. NNN completed $823,781,000 and $410,969,000 of real estate acquisitions during the year ended December 31, 2025 and 2024, respectively. Additionally, NNN invested $107,236,000 and $154,447,000 of work in progress and improvements during the year ended December 31, 2025 and 2024, respectively.
Lease Accounting | Lease Accounting. NNN records its leases on the Property Portfolio in accordance with FASB ASC Topic 842, Leases ("ASC 842"). NNN's real estate is predominantly leased to tenants under triple-net leases, whereby the tenant is responsible for all operating expenses relating to the Property, including utilities, real estate taxes and assessments, property and liability insurance, maintenance, repairs and capital expenditures. Substantially all the leases on the Property Portfolio are classified as operating leases and are accounted for as follows: Operating method – Properties with leases accounted for using the operating method are recorded at the cost of the real estate and depreciated on the straight-line method over their estimated remaining useful lives, which typically range from 20 to 40 years for buildings and improvements and 15 years for land improvements. Leasehold interests are amortized on the straight-line method over the terms of their respective leases. Revenue is recognized as rentals are earned and expenses (including depreciation) are charged to operations as incurred. When scheduled rentals vary during the lease term, income is recognized on a straight-line basis so as to produce a constant periodic rent over the term of the lease. Accrued rental income is the aggregate difference between the scheduled rents which vary during the lease term and the income recognized on a straight-line basis. NNN adopted certain practical expedients in ASC 842 and does not separate the non-lease components from the lease components when the timing and patterns of transfer for the lease and non-lease components are the same and the lease is classified as an operating lease. As a result, all income earned pursuant to tenant leases is reflected as one-line, rental income, in the Consolidated Statements of Income and Comprehensive Income. In addition, NNN records right-of-use assets and operating lease liabilities as lessee under operating leases in accordance with ASC 842.
Collectability | Collectability. 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), historical bad debt levels, tenant credit-worthiness and current economic trends, all of which assist in evaluating the probability of outstanding and future rental income collections and the adequacy of the allowance for doubtful accounts. 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. When NNN deems the collection of rental income from a tenant not probable, uncollected and previously recognized rental revenue and any related accrued rent are reversed as a reduction to rental income and, subsequently, rental income is only recognized when cash receipts are received. At this point, a tenant is deemed cash basis for accounting purposes. If NNN subsequently deems the collection of rental income is probable, any related accrued rental income or expense is restored. As a result of the review of collectability, NNN recorded a write-off of $2,630,000, $763,000 and $204,000 of outstanding receivables and related accrued rent during the years ended December 31, 2025, 2024 and 2023, respectively, and reclassified certain tenants as cash basis for accounting purposes. The following table summarizes those tenants classified as cash basis for accounting purposes as of December 31:
|  | 2025 |  |  | 2024 |  |  | 2023 |  |
Number of tenants |  |  | 14 |  |  |  | 12 |  |  |  | 9 |  |
Cash basis tenants as a percent of: |  |  |  |  |  |  |  |  |  |
Total Properties |  |  | 1.8 | % |  |  | 2.5 | % |  |  | 3.5 | % |
Total Annualized Base Rent ("ABR")(1) |  |  | 4.4 | % | (2) |  | 4.3 | % | (3) |  | 5.0 | % | (4)
Total gross leasable area |  |  | 7.1 | % |  |  | 4.5 | % |  |  | 4.8 | % |
(1) | ABR represents the monthly cash base rent for all leases in place as of the end of the period multiplied by 12. Based on ABR of:
| (2) | $928,081,000 as of December 31, 2025.
| (3) | $860,562,000 as of December 31, 2024.
| (4) | $818,749,000 as of December 31, 2023.
During the years ended December 31, 2025, 2024 and 2023, NNN recognized $35,717,000, $39,495,000 and $56,229,000, respectively, of rental income from certain tenants for periods following their classification to cash basis for accounting purposes. During the year ended December 31, 2023, one tenant was reclassified to accrual basis for accounting purposes due to their improved qualitative and/or quantitative credit factors. More information regarding the reclassification can be found in "Note 2 – Real Estate". NNN includes an allowance for doubtful accounts in rental income on the Consolidated Statements of Income and Comprehensive Income.
Real Estate - Held for Sale | Real Estate – Held For Sale. Real estate held for sale is not depreciated and is recorded at the lower of cost or fair value, less cost to sell. On a quarterly basis, the Company evaluates its Properties for held for sale classification based on specific criteria as outlined in FASB ASC Topic 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. At December 31, 2025 and 2024, NNN had recorded real estate held for sale of $21,198,000 (10 properties) and $283,000 (two properties), respectively, in real estate portfolio on the Consolidated Balance Sheets. The properties classified as held for sale as of December 31, 2024 were sold during the year ended December 31, 2025.
Real Estate Dispositions | Real Estate Dispositions. When real estate is disposed, the related cost, accumulated depreciation or amortization and any accrued rental income from operating leases and the net investment from direct financing leases are removed from the accounts and gains and losses from the dispositions are reflected in income. FASB ASC Topic 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets ("ASC 610-20"), provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. An entity that transfers a nonfinancial asset in the scope of ASC 610-20 follows a two-step derecognition model to determine whether (and when) to derecognize the asset. NNN determined the key revenue stream impacted by ASC 610-20 is gain on disposition of real estate reported on the Consolidated Statements of Income and Comprehensive Income. In accordance with ASC 610-20, NNN evaluates any separate contracts or performance obligations to determine proper timing and/or amount of revenue recognition, as well as transfer of control and transaction price allocation in determining the amount of gain or loss to record.
Impairment - Real Estate | 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 under contract and/or 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 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 predominantly leased to tenants under long-term net leases and held for investment. In most cases, NNN's Property leases provide for initial terms of 10 to 20 years, with cash flows provided over the entire term.
Credit Losses on Financial Instruments | Credit Losses on Financial Instruments. FASB ASC Topic 326, Financial Instruments – Credit Losses, 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. NNN held mortgages receivable, including accrued interest, of $454,000 included in other assets on the Consolidated Balance Sheets as of December 31, 2024, net of $9,000 allowance for credit loss. As of December 31, 2025, NNN held no mortgages receivable.
Cash and Cash Equivalents | Cash and Cash Equivalents. NNN considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of cash and money market accounts. Cash equivalents are stated at cost plus accrued interest, which approximates fair value. Cash accounts maintained on behalf of NNN in demand deposits at commercial banks and money market funds may exceed federally insured levels or may be held in accounts without any federal insurance or any other insurance or guarantee. However, NNN has not experienced any losses in such accounts.
Restricted Cash and Cash Held in Escrow | Restricted Cash and Cash Held in Escrow. Restricted cash and cash held in escrow may include (i) cash proceeds from the sale of assets held by qualified intermediaries in anticipation of the acquisition of replacement properties in tax-deferred exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended (the "Code"), (ii) cash that has been placed in escrow for the future funding of construction commitments, or (iii) cash that is not immediately available to NNN. NNN held $776,000 and $331,000 in restricted cash and cash held in escrow as of December 31, 2025 and 2024, respectively.
Debt Costs | Debt Costs – Line of Credit Payable. Debt costs incurred in connection with NNN's $1,200,000,000 unsecured revolving 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 had costs of $6,248,000 and $8,958,000, included in debt costs on the Consolidated Balance Sheets, as of December 31, 2025 and 2024, respectively, net of accumulated amortization of $29,898,000 and $27,002,000, respectively. Debt Costs – Term Loan. Debt costs incurred in connection with the closing of NNN's $300,000,000 senior unsecured term loan 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 had costs of $2,397,000 included in debt costs on the Consolidated Balance Sheets, as of December 31, 2025, net of accumulated amortization of $32,000. Debt Costs – Notes Payable. Debt costs incurred in connection with the issuance of NNN's unsecured notes have been deferred and are being amortized to interest expense over the term of the respective debt obligation using the effective interest method. NNN had debt costs of $44,420,000 and $43,820,000, included in notes payable on the Consolidated Balance Sheets, as of December 31, 2025 and 2024, respectively, net of accumulated amortization of $13,750,000 and $14,060,000, respectively.
Revenue Recognition | Revenue Recognition. Rental revenues for properties under construction commence upon completion of construction and delivery of the leased asset to the tenant. Rental revenues for non-development real estate assets are recognized when earned in accordance with ASC 842, based on the terms of the lease of the leased asset. Leasehold interests are amortized on the straight-line method over the terms of their respective leases. When scheduled rentals vary during the lease term, income is recognized on a straight-line basis so as to produce a constant periodic rent over the term of the lease. Lease termination fees are recognized when collected subsequent to the related lease that is cancelled and NNN no longer has continuing involvement with the former tenant with respect to that property.
Earnings Per Share | Earnings Per Share. Earnings per share have been computed in accordance with FASB ASC Topic 260, Earnings Per Share. The guidance requires classification of the Company's unvested restricted share units, which contain 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 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 share using the two-class method for the years ended December 31 (dollars in thousands):
|  | 2025 |  |  | 2024 |  |  | 2023 |
Basic and Diluted Earnings: |  |  |  |  |  |  |  |  |
Net earnings |  | $ | 389,777 |  |  | $ | 396,835 |  |  | $ | 392,340 |
Less: Earnings allocated to unvested restricted shares |  |  | (728 | ) |  |  | (686 | ) |  |  | (609 | )
Net earnings used in basic and diluted earnings per share |  | $ | 389,049 |  |  | $ | 396,149 |  |  | $ | 391,731 |
Basic and Diluted Weighted Average Shares Outstanding: |  |  |  |  |  |  |  |  |
Weighted average shares outstanding |  |  | 188,651,928 |  |  |  | 184,723,988 |  |  |  | 182,184,038 |
Less: Unvested restricted shares |  |  | (308,239 | ) |  |  | (299,534 | ) |  |  | (273,077 | )
Less: Unvested contingent restricted shares |  |  | (732,238 | ) |  |  | (735,892 | ) |  |  | (710,921 | )
Weighted average shares outstanding used in basic earnings per share |  |  | 187,611,451 |  |  |  | 183,688,562 |  |  |  | 181,200,040 |
Other dilutive securities |  |  | 375,347 |  |  |  | 355,279 |  |  |  | 489,683 |
Weighted average shares outstanding used in diluted earnings per share |  |  | 187,986,798 |  |  |  | 184,043,841 |  |  |  | 181,689,723 |
Income Taxes | Income Taxes. NNN has made an election to be taxed as a REIT under Sections 856 through 860 of the Code, and related regulations. NNN generally will not be subject to federal income taxes on taxable income it distributes to stockholders, provided it meets certain other requirements for qualifying as a REIT. NNN believes it has been organized as and its past and present operations qualify NNN as a REIT. Notwithstanding NNN's qualification for taxation as a REIT, NNN is subject to certain state and local income, franchise and excise taxes. NNN may elect to treat certain subsidiaries as TRS pursuant to the provisions of the REIT Modernization Act. A TRS is able to engage in activities resulting in income that previously would have been disqualified from being eligible REIT income under the federal income tax regulations. As a result, certain activities of NNN which occur within its TRS entities are subject to federal and state or local income taxes. All provisions for federal income taxes in the accompanying consolidated financial statements are attributable to NNN's former TRS. The deferred tax asset consists only of net operating loss carryforwards of $3,779,000 from the former TRS that begin to expire in 2026. Management believes it is unlikely that NNN will realize any of the benefits of these deductible differences and has taken a valuation allowance against them. The valuation allowance decreased by $25,000 and $95,000 for the years ended December 31, 2025 and 2024, respectively, as a result of the decrease in the deferred tax asset. There was no change to the valuation allowance for the year ended December 31, 2023. NNN currently has no TRS entities. Income taxes are accounted for under the asset and liability method as required by FASB ASC Topic 740, Income Taxes ("ASC 740"). Deferred tax assets and liabilities are recognized for the temporary differences based on estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the applicable period. In accordance with ASC 740, NNN has analyzed its various federal and state filing positions. NNN believes that its income tax filing positions and deductions are well documented and supported. Additionally, NNN believes that its accruals for tax liabilities are adequate. Therefore, no reserves for uncertain income tax positions have been recorded. NNN has had no unrecognized tax benefits during any of the years presented. Further, no interest or penalties have been included since no reserves were recorded and no significant increases or decreases are expected to occur within the next 12 months. When applicable, such interest and penalties will be recorded in non-operating expenses. The periods that remain open under federal statute are 2022 through 2025. NNN also files in many states and localities with varying open years under statute.
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 FASB ASC Topic 820, Fair Value Measurement ("ASC 820"). 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) | Accumulated Other Comprehensive Income (Loss). The following table outlines the changes in accumulated other comprehensive income (loss) for the years ended December 31, 2025 and 2024 (dollars in thousands):
|  | Gain or Loss on Cash Flow Hedges(1) |  |
Beginning balance, December 31, 2023 |  | $ | (10,111 | ) |
Reclassifications from accumulated other comprehensive income to net earnings |  |  | 2,152 |  | (2)
Ending balance, December 31, 2024 |  |  | (7,959 | ) |
Other comprehensive income (loss) |  |  | (52 | ) |
Reclassifications from accumulated other comprehensive income to net earnings |  |  | 1,690 |  | (2)
Ending balance, December 31, 2025 |  | $ | (6,321 | ) |
(1) | Additional disclosure is included in "Note 8 – Derivatives."
(2) | Recorded in interest expense on the Consolidated Statements of Income and Comprehensive Income. There is no income tax expense (benefit) resulting from this reclassification.
New Accounting Pronouncements | New Accounting Pronouncements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), effective for annual periods beginning after December 15, 2024. The amendments in the update require public business entities on an annual basis to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold of equal to or greater than five percent of the amount computed by multiplying pretax income by the statutory income tax rate. The amendments also require that entities disclose on an annual basis information about the amount of income taxes paid disaggregated by federal, state and foreign taxes and the amount of income taxes paid disaggregated by individual jurisdictions in which income taxes paid is equal to or greater than five percent of total income taxes paid. The amendments eliminate some of the previous required disclosures for all entities relating to estimates of the change in unrecognized tax benefits reasonably possible within 12 months. NNN has evaluated ASU 2023-09 and determined it will have no material impact on its future disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expense ("ASU 2024-03"), effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The amendments in this update require disclosure, in the notes to the financial statements, of specified information about certain costs and expenses and a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. NNN is currently evaluating the potential impact the adoption of ASU 2024-03 will have on its future disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets ("ASU 2025-05"), effective for annual periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The amendments in this update provide all entities with a practical expedient, which allows entities to assume current conditions as of the balance sheet date do not change for the remaining life of the asset, in developing reasonable and supportable forecasts as part of estimating expected credit losses. NNN has evaluated ASU 2025-05 and determined it will have no material impact on its future disclosures. In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements ("ASU 2025-09"), effective for annual and interim reporting periods beginning after December 15, 2026. The amendments in this update (i) expand the hedged risks permitted to be aggregated in a group of individual forecasted transactions in a cash flow hedge by changing the requirement to designate a group of individual forecasted transactions from having a shared risk exposure to having a similar risk exposure, (ii) provide a model to facilitate the application of cash flow hedge accounting to forecasted interest payments on variable-rate debt instruments with contractual terms that permit the borrower to change the interest rate index and interest rate tenor upon which interest is accrued, (iii) expand hedge accounting for forecasted purchases and sales of nonfinancial assets, (iv) improve generally accepted accounting principles by updating the hedge accounting guidance to accommodate differences in the loan and swap markets that developed after the cessation of the London Interbank Offered Rate, and (v) eliminate the recognition and presentation mismatch related to foreign-currency-denominated debt instrument both designed as the hedging instrument in a net investment hedge and designed as the hedged item in a fair value hedge of interest rate risk. NNN is currently evaluating the potential impact the adoption of ASU 2025-09 will have on its future disclosures.
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 which are required to prepare the consolidated financial statements in conformity with accounting principles generally accepted in the United States ("U.S."). Significant accounting policies include management's estimates of the purchase accounting for acquisition of real estate, the recoverability of the carrying value of long-lived assets and management's evaluation of the probability of outstanding and future lease payment collections. Estimates are sensitive to evaluations by management about current and future expectations of market and economic conditions. Actual results could differ from those estimates.
