Direct Financing Leases

Income under direct financing leases is included in revenues from rental properties and is recognized over the lease terms using the effective interest rate method which produces a constant periodic rate of return on the net investments in the leased properties. The investments in direct financing leases are increased for interest income earned and amortized over the life of the leases and reduced by the receipt of lease payments. We consider direct financing leases to be past-due or delinquent when a contractually required payment is not remitted in accordance with the provisions of the underlying agreement.

On June 16, 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments (“ASU 2016-13”). For additional information regarding our direct financing leases, see Note 3 - Leases.

We review our direct financing leases each reporting period to determine whether there were any indicators that the value of our net investments in direct financing leases may be impaired and adjust the allowance for any estimated changes in the credit loss with the resulting change recorded through our consolidated statement of operations. When determining a possible impairment, we take into consideration the collectability of direct financing lease receivables for which a reserve would be required. In addition, we determine whether there has been a permanent decline in the current estimate of the residual value of the property. There were no indicators of impairment related to any of our direct financing leases during the three and nine months ended September 30, 2026 and 2025, and, accordingly, we did not record any additional allowance for credit losses in either period.

When we enter into a contract to sell properties that are recorded as direct financing leases, we evaluate whether we believe that it is probable that the disposition will occur. If we determine that the disposition is probable and therefore the property’s holding period is reduced, we may adjust an allowance for credit losses to reflect the change in the estimate of the undiscounted future rents. Accordingly, the net investment balance is written down to fair value.

Notes and Mortgages Receivable

Notes and mortgages receivable consists of loans originated by us in conjunction with property dispositions and funding provided to tenants in conjunction with property acquisitions and capital improvements. Notes and mortgages receivable are recorded at stated principal amounts. We estimated our credit loss reserve for our notes and mortgages receivable using the weighted average remaining maturity (“WARM”) method, which has been identified as an acceptable loss-rate method for estimating credit loss reserves in the FASB Staff Q&A Topic 326, No. 1. The WARM method requires us to reference historic loan loss data across a comparable data set and apply such loss rate to our notes and mortgages portfolio over its expected remaining term, taking into consideration expected economic conditions over the relevant timeframe. We applied the WARM method for our notes and mortgages portfolio, which share similar risk characteristics. Application of the WARM method to estimate a credit loss reserve requires significant judgment, including (i) the historical loan loss reference data, (ii) the expected timing and amount of loan repayments, and (iii) the current credit quality of our portfolio and our expectations of performance and market conditions over the relevant time period. To estimate the historic loan losses relevant to our portfolio, we used our historical loan performance since the launch of our loan origination business in 2013. As of September 30, 2026 and December 31, 2025, the allowance for credit losses on notes and mortgages receivable was $0.3 million.

We also originate construction loans and provide development financing for the construction of income-producing properties which we generally expect to acquire via sale-leaseback transactions at the end of the construction period. During the nine months ended September 30, 2026, we funded $19.3 million and, as of September 30, 2026, had outstanding $19.3 million of such construction loans and development financing. Our construction loans and development financing generally provide for funding only during the construction period, and funds are disbursed based on inspections in accordance with a schedule reflecting the completion of portions of the projects. At the end of the construction period, the construction loans will be repaid with the proceeds from the sale of the properties.

Revenue Recognition and Deferred Rent Receivable

Lease payments from operating leases are recognized on a straight-line basis over the term of the leases. The cumulative difference between lease revenue recognized under this method and the contractual lease payment terms is recorded as deferred rent receivable on our consolidated balance sheets. We review our accounts receivable, including its deferred rent receivable, related to base rents, straight-line rents, tenant reimbursements and other revenues for collectability. Our evaluation of collectability primarily consists of reviewing past due account balances and considers such factors as the credit quality of our tenant, historical trends of the tenant, changes in tenant payment terms, current economic trends, and other facts and circumstances related to the applicable tenants. In addition, with respect to tenants in bankruptcy, we estimate the probable recovery through bankruptcy claims. If a tenant’s accounts receivable balance is considered uncollectible, we will write off the related receivable balances and cease to recognize lease income, including straight-line rent unless cash is received. If the collectability assessment subsequently changes to probable, any difference between the lease income that would have been recognized if collectability had always been assessed as probable and the lease income recognized to date, is recognized as a current-period adjustment to revenues from rental properties. Our reported net earnings are directly affected by our estimate of the collectability of our accounts receivable.

The present value of the difference between the fair market rent and the contractual rent for leases at the time properties are acquired is amortized into revenues from rental properties over the remaining terms of the in-place leases. Lease termination fees are recognized as other income when earned upon the termination of a tenant’s lease and relinquishment of space in which we have no further obligation to the tenant.

The sales of nonfinancial assets, such as real estate, are to be recognized when control of the asset transfers to the buyer, which will occur when the buyer has the ability to direct the use of or obtain substantially all of the remaining benefits from the asset. This generally occurs when the transaction closes and consideration is exchanged for control of the property.

Impairment of Long-Lived Assets

Assets are written down to fair value when events and circumstances indicate that the assets might be impaired and the projected undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. Assets held for disposal are written down to fair value less estimated disposition costs.

The estimated fair value of real estate is based on the price that would be received from the sale of the property in an orderly transaction between market participants at the measurement date. In general, we consider multiple internal valuation techniques when measuring the fair value of a property, all of which are based on unobservable inputs and assumptions that are classified within Level 3 of the Fair Value Hierarchy. These assessments have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future rental rates and operating expenses that could differ materially from actual results in future periods. Where properties held for use have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the projected undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. This requires significant judgment. In some cases, the results of whether impairment is indicated are sensitive to changes in assumptions input into the estimates, including the holding period until expected sale.

We recorded impairments aggregating $0.4 million and $4.4 million for the three and nine months ended September 30, 2026, respectively, and $0.7 million and $2.3 million for the three and nine months ended September 30, 2025, respectively. Our estimated fair values, as they relate to property carrying values, were primarily based on estimated sales prices from third-party offers, including signed contracts, letters of intent, or indicative bids (for which we do not have access to the unobservable inputs) used to determine these estimated fair values, and/or consideration of the estimated amount currently required to replace the asset, as adjusted for obsolescence, and resulted in $3.1 million and $0.7 million of impairment charges during the nine months ended September 30, 2026 and 2025, respectively. During the nine months ended September 30, 2026 and 2025, the remaining impairments of $1.3 million and $1.6 million, respectively, were due to the accumulation of asset retirement costs as a result of changes in estimates associated with our estimated environmental liabilities which increased the carrying values of certain properties in excess of their fair values. Impairments relating to properties that were previously disposed of by us, included in the amounts above, were $0.4 million and $0.7 million for the nine months ended September 30, 2026 and 2025, respectively.

Fair Value of Financial Instruments

All of our financial instruments are reflected in the accompanying consolidated balance sheets at amounts which, in our estimation based upon an interpretation of available market information and valuation methodologies, reasonably approximate their fair values, except those separately disclosed in the notes below.

The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates of fair value that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the period reported using a hierarchy (the “Fair Value Hierarchy”) that prioritizes the inputs to valuation techniques used to measure the fair value. The Fair Value Hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels of the Fair Value Hierarchy are as follows: “Level 1” – inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date; “Level 2” – inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and “Level 3” – inputs that are unobservable. Certain types of assets and liabilities are recorded at fair value either on a recurring or non-recurring basis. Assets required or elected to be marked-to-market and reported at fair value every reporting period are valued on a recurring basis. Other assets not required to be recorded at fair value every period may be recorded at fair value if a specific provision or other impairment is recorded within the period to mark the carrying value of the asset to market as of the reporting date. Such assets are valued on a non-recurring basis.

Environmental Remediation Obligations

We record the fair value of an environmental remediation obligation as an asset and liability when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. Environmental remediation obligations are estimated based on the level and impact of contamination at each property. The accrued liability is the aggregate of our estimate of the fair value of cost for each component of the liability. The accrued liability is net of estimated recoveries from state underground storage tank (“UST”) remediation funds considering estimated recovery rates developed from prior experience with the funds. Net environmental liabilities are currently measured based on their expected future cash flows which have been adjusted for inflation and discounted to present value. We accrue for environmental liabilities that we believe are allocable to other potentially responsible parties if it becomes probable that the other parties will not pay their environmental remediation obligations. For additional information regarding environmental obligations, see Note 7 – Environmental Obligations.

Income Taxes

We file a federal income tax return on which we consolidate our tax items and the tax items of our subsidiaries that are pass-through entities. Effective January 1, 2001, we elected to qualify, and believe that we are operating so as to qualify, as a REIT for federal income tax purposes. Accordingly, we generally will not be subject to federal income tax on qualifying REIT income, provided that distributions to our stockholders equal at least the amount of our taxable income as defined under the Internal Revenue Code. We accrue for uncertain tax matters when appropriate. The accrual for uncertain tax positions is adjusted as circumstances change and as the uncertainties become more clearly defined, such as when audits are settled or exposures expire. Tax returns filed for the years ended December 31, 2022, 2023, 2024, and tax returns which will be filed for the year ended December 31, 2025, remain open to examination by federal and state tax jurisdictions under the respective statutes of limitations.

New Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027,with early adoption permitted. We are currently evaluating the impact of adopting ASU 2024-03.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 is intended to clarify and improve certain aspects of interim financial reporting, including the requirements for interim disclosures and the application of recognition and measurement guidance in interim periods. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2026. We are currently evaluating the potential impact of the guidance and potential additional disclosures required.
