Table of Contents Explanatory Note

In the narrative portion of this Annual Report on Form 10-K, except as otherwise indicated or the context otherwise requires:

the information with respect to our consolidated joint ventures is generally described as if such ventures are our wholly owned subsidiaries and information with respect to unconsolidated joint ventures is generally separately described.
(i) all references to joint ventures refer to unconsolidated joint ventures, (ii) all interest rates with respect to debt give effect to the related interest rate derivative, if any, (iii) amounts reflected as debt reflect the gross debt owed, without deducting deferred financing costs and (iv) references to industrial properties include properties (a) a portion of which may be used for office purposes and (b) that are used for distribution, warehouse and flex purposes.
--- ---
the term “standard carve-outs,” when used in describing mortgages or mortgage financings, refers to recourse items to an otherwise non-recourse mortgage. While carve-outs vary from lender to lender and transaction to transaction, the carve-outs may include, among other things, voluntary bankruptcy filings, environmental liabilities, the sale, financing or encumbrance of the property in violation of loan documents, damage to property as a result of intentional misconduct or gross negligence, failure to pay valid taxes and other claims which could create liens on the property and the conversion of security deposits, insurance proceeds or condemnation awards.
--- ---
we present information regarding our 2026 base rent which does not reflect, among other things, variable rent (including amounts tenants are required to reimburse us) or the adjustments required by United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) to present rental income. We view base rent as an operating – not a financial – metric and present it because we believe investors are interested in knowing the amount of cash rent we are entitled to collect. Base rent is not a substitute for rental income, as determined in accordance with GAAP, and may not be comparable from year–to–year or to similar metrics presented by other REITs. See “Item 1. BusinessOur Tenants”.
--- ---
we refer to certain entities as “affiliated entities” because such entities share with us certain executive personnel and ownership. Our “affiliated entities” include Gould Investors L.P. (“Gould Investors”), a master limited partnership involved primarily in the ownership and operation of a diversified portfolio of real estate assets, BRT Apartments Corp. (“BRT”), a NYSE listed multi-family REIT and Majestic Property Management LLC (“Majestic Property”), a property management company which compensates certain of our executive officers, and which is indirectly owned by, among others, Matthew J. Gould, the Company’s chairman, and Jeffrey A. Gould, a director and senior vice president of the Company. The use of such term does not constitute an acknowledgement that such entities are affiliates (as such term is used in the Securities Act (as defined below) or Exchange Act (as defined below)) of ours or one another.

Cautionary Note Regarding Forward-Looking Statements

This Annual Report on Form 10-K, together with other statements and information publicly disseminated by us, contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We intend such forward-looking statements to be covered by the safe harbor provision for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and include this statement for purposes of complying with these safe harbor provisions. Forward-looking statements, which are based on certain assumptions and describe our future plans, strategies and expectations, are generally identifiable by use of the words “may,” “will,” “could,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project,” or similar expressions or variations thereof and include, without limitation, statements regarding our future estimated base rent, funds from operations, adjusted funds from operations and our dividend. Among other things, forward looking statements with respect to (i) estimates of base rent and rental income exclude variable rent (including tenant reimbursements) and the adjustments required by GAAP to present rental income, (ii) estimates of base rent may not, unless otherwise expressly indicated, reflect the expenses (e.g., real estate expenses, interest, depreciation and amortization or any one or more of the foregoing) with respect to the associated property, (iii) anticipated property purchases, sales, financings and/or refinancings may not be 1

Table of Contents completed during the period or on the terms indicated or at all, (iv) estimates of gains from property sales or proceeds from financing or refinancing transactions are subject to adjustment, among other things, because actual closing costs may differ from the estimated costs and (v) anticipated rent increases, including those tied to filling of vacancies or as a result of market-to-market opportunities (i.e., renewing leased premises at higher rental rates) may not be realized.

The uncertainties, risks and factors which may cause actual results to differ materially from current expectations include, but are not limited to:

the financial failure of, or other default in payment by, tenants under their leases and the potential resulting vacancies;
adverse changes and disruption in the sectors in which our tenants operate which could impact our tenants’ ability to pay rent and expense reimbursement;
--- ---
the level and volatility of interest rates;
--- ---
loss or bankruptcy of one or more of our tenants, and bankruptcy laws that may limit our remedies if a tenant becomes bankrupt and rejects its lease;
--- ---
general economic and business conditions and developments, including those currently affecting or that may affect our economy;
--- ---
general and local real estate conditions, including any changes in the value of our real estate;
--- ---
our ability to renew or re-lease space as leases expire;
--- ---
our ability to pay dividends;
--- ---
the effect of changes in political conditions in the U.S., including in connection with the administration’s policies and priorities, or otherwise;
--- ---
changes in governmental laws and regulations relating to real estate and related investments;
--- ---
compliance with credit facility and mortgage debt covenants;
--- ---
the availability of, and costs associated with, sources of capital and liquidity;
--- ---
competition in our industry;
--- ---
technological changes, such as artificial intelligence, autonomous vehicles, reconfiguration of supply chains, robotics, 3D printing or other technologies;
--- ---
potential natural disasters, epidemics, pandemics or outbreak of infectious disease, such as COVID-19, and other potentially catastrophic events such as acts of war and/or terrorism; and
--- ---
the other risks, uncertainties and factors described in the reports and documents we file with the SEC including the risks, uncertainties and factors described under “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report on Form 10-K, and in the Quarterly Reports on Form 10-Q and the other reports we file with the SEC.
--- ---

In light of the factors referred to above, the future events discussed or incorporated by reference in this report and other documents we file with the SEC may not occur, and actual results, performance or achievements could differ materially from those anticipated or implied in the forward-looking statements.  Given these uncertainties, you should not rely on any forward-looking statements.

Except as may be required under the U.S. federal securities laws, we undertake no obligation to publicly update our forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further disclosures we make in our reports that are filed with or furnished to the SEC. 2

Item 1. Business.

General

We are a self-administered and self-managed real estate investment trust, also known as a REIT. We acquire, own and manage a geographically diversified portfolio consisting primarily of industrial properties.

As of December 31, 2025:

we own 103 properties with an aggregate of approximately 11.8 million square feet and located in 30 states;
our 2026 base rent (as described in “— Our Tenants”) is $82.7 million;
--- ---
the occupancy rate of our properties is 98.5% based on square footage;
--- ---
the weighted average remaining term of our $522.5 million mortgage debt is 5.8 years and the weighted average interest rate thereon is 4.88%; and
--- ---
the weighted average remaining term of the leases generating our 2026 base rent is 4.4 years.
--- ---

As of February 1, 2026 and after giving effect to the ten industrial properties we acquired in January 2026, we own 113 properties with approximately 12.5 million square feet, including 79 industrial properties with approximately 11.0 million square feet, and we anticipate that our industrial properties will generate approximately 81.6% of our 2026 base rent. See “ –Recent Developments.”

We maintain a website at www.1liberty.com. The reports and other documents that we electronically file with, or furnish to, the SEC pursuant to Section 13 or 15(d) of the Exchange Act can be accessed through this site, free of charge, as soon as reasonably practicable after we electronically file or furnish such reports. These filings are also available on the SEC’s website at www.sec.gov. The information on our website is not part of this report.

2025 Activities

In 2025, we:

acquired 13 industrial properties for an aggregate purchase price of $188.8 million, including $112.3 million in mortgage debt. These properties account for $12.5 million, or 15.1%, of our 2026 base rent and we anticipate that in 2026, these properties will generate $13.3 million of rental income (excluding tenant reimbursements), $8.4 million of depreciation and amortization expense and $6.5 million of interest expense.
sold ten properties (i.e., seven retail, a restaurant, a veterinary hospital and a property ground leased to a multi-unit apartment complex owner/operator) for an aggregate net sales proceeds of $58.9 million and an aggregate net gain on sale of real estate of $18.7 million. The properties sold accounted for $2.4 million, or 2.4%, and $4.5 million, or 5.0%, of 2025 and 2024 rental income, net, respectively.
--- ---
sold two joint venture properties - our 50% share of the (i) net sales proceeds was $2.4 million and (ii) gain on sales was $991,000.

Table of Contents Recent Developments

We purchased, on January 29, 2026, a 637,633 square foot portfolio comprised of ten industrial properties (the “Portfolio Acquisition”) located in seven markets and leased to six tenants each of which has a global or national presence, for $56.7 million, including new mortgage debt on six of the properties of $17.0 million bearing an interest rate of 5.53% and maturing in 2033. We also borrowed $30.0 million from our credit facility (which bears a fluctuating interest rate of 5.45% at January 29, 2026) in connection with this purchase. We anticipate paying down our credit facility debt from the net proceeds of property sales and mortgage financing on two of the unencumbered properties included in the Portfolio Acquisition. As of January 29, 2026, the base rent in 2026 for these properties is approximately $2.8 million, and we estimate that after giving effect to anticipated lease renewals (as to which no assurance can be provided), the 2026 base rent for these properties will be approximately $3.6 million. We also estimate that in 2026, these properties will generate $2.6 million of interest expense (including $1.7 million of such expense from the credit facility assuming an interest rate of 5.45% and that $30.0 million remains outstanding thereon).

As of February 27, 2026, $30.0 million is outstanding under our credit facility bearing a floating rate of interest of 5.42% per year.

Pending Transactions

We entered into a contract in:

October 2025, to sell a vacant retail property located in Cary, North Carolina for $6.0 million. It is anticipated the (i) property will be sold in March 2026 and (ii) sale will result in a gain of approximately $2.5 million, which will be recognized as Gain on sale of real estate, net, in the consolidated statement of income for the quarter ending March 31, 2026. This property accounted for $192,000 and $460,000 of rental income, net, $93,000 and $93,000 of depreciation and amortization expense, and $45,000 and $110,000 of mortgage interest expense for 2025 and 2024, respectively.
January 2026, to sell a retail property located in Newport News, Virginia for $4.2 million. It is anticipated the (i) property will be sold in April 2026 and (ii) sale will result in a gain of approximately $1.3 million, which will be recognized as Gain on sale of real estate, net, in the consolidated statements of income for the three and six months ending June 30, 2026. This property accounted for $360,000 and $340,000 of rental income, net, and $115,000 and $113,000 of depreciation and amortization expense for 2025 and 2024, respectively.
--- ---
January 2026, to purchase 14 acres of land for $800,000 adjacent to one of the Columbia, SC properties acquired in the Portfolio Acquisition.

Our Business Objective

Our business objective is to increase stockholder value by:

identifying opportunistic and strategic industrial property acquisitions consistent with our portfolio and our acquisition strategies;
monitoring and maintaining our portfolio, and as appropriate, working with tenants to facilitate the continuation or expansion of their tenancies;
--- ---
managing our portfolio effectively, including opportunistic and strategic property sales;
--- ---
obtaining mortgage indebtedness (including refinancings) on favorable terms, ensuring that the cash flow generated by a property exceeds the debt service thereon and maintaining access to capital to finance property acquisitions; and
--- ---
maintaining and, over time, increasing our dividend.
--- ---

Table of Contents Acquisition Strategy

We seek to acquire industrial properties throughout the U.S. that have locations, demographics and other investment attributes that we believe to be attractive. We generally focus on properties in secondary or tertiary markets (preferably markets in which we believe there is a limited supply for new industrial space or that have other barriers to entry), that are (or that we believe in the near term, will be) fully leased and that provide for periodic rent increases. In evaluating a potential acquisition, we blend fundamental real estate analysis with an evaluation of the prospective tenant’s credit worthiness analysis to make an assessment of profitable cash flows that will be realized in future periods.

Generally, we hold the properties we acquire for an extended period of time. Our investment criteria are intended to identify properties from which increased asset value and overall return can be realized from an extended period of ownership. Although our investment criteria favor an extended period of ownership, we will dispose of a property if we regard the disposition of the property as an opportunity to realize the overall value of the property sooner or to avoid future risks by achieving a determinable return from the property.

We identify properties through the network of contacts of our senior management, which contacts include real estate brokers, private equity firms, banks and law firms. In addition, we attend industry conferences and engage in direct solicitations.

Our charter documents do not limit the number of properties in which we may invest, the amount or percentage of our assets that may be invested in any specific property or property type, or the concentration of investments in any region in the U.S. We do not intend to acquire properties located outside of the U.S. We will continue to form entities to acquire interests in real properties, either alone or with other investors, and we may acquire interests in joint ventures or other entities that own real property.

It is our policy, and the policy of our affiliated entities, that any investment opportunity presented to us or to any of our affiliated entities that involves the acquisition of a net leased property, a ground lease (other than a ground lease of a multi-family property) or a community shopping center, will first be offered to us and may not be pursued by any of our affiliated entities unless we decline the opportunity. Further, to the extent our affiliates are unable or unwilling to pursue an acquisition of a multi-family property (including a ground lease of a multi-family property), we may pursue such transaction if it meets our investment objectives.

Investment Evaluation

In evaluating potential investments, we consider, among other criteria, the following:

the current and projected cash flow of the property;
the estimated return on equity to us;
--- ---
an evaluation of the property and improvements, given its location and use;
--- ---
an evaluation of the credit quality of the tenant;
--- ---
alternate uses or tenants for the property;
--- ---
local demographics (population and rental trends);
--- ---
the purpose for which the property is used;
--- ---
the terms of tenant leases, including the relationship between current rents and market rents;
--- ---
the potential to finance and/or refinance the property;
--- ---
the projected residual value of the property;
--- ---
the ability of the tenant to meet operational needs and lease obligations;
--- ---
potential for income and capital appreciation;
--- ---
occupancy of and demand for similar properties in the market area; and
--- ---
the ability of a tenant and the related property to withstand changing economic conditions and other challenges.

Table of Contents Our Tenants

The following table sets forth information about our tenants by industry sector as of December 31, 2025:

(a) Our 2026 base rent represents, after giving effect to any abatements, concessions, deferrals or adjustments, the base rent payable to us in 2026 through the stated expiration of such leases, under leases in effect at December 31, 2025. Our 2026 base rent (i) includes $354,000 of base rent from a retail property in Newport News, Virginia which we anticipate will be sold in April 2026 and (ii) excludes $2.8 million of base rent from the Portfolio **** Acquisition.
--- ---
(b) Includes an office property (located in Brooklyn, New York, leased to one tenant which accounts for $1.3 million, or 1.6%, of 2026 base rent), two theaters, a health and fitness center and a restaurant.
--- ---

Our base rent for 2025, as reported in our Annual Report on Form 10-K for the year ended December 31, 2024 (under the title “2025 Contractual Rental Income) was $72 million.

Our Leases

Under most of our leases the tenant, in addition to its rental obligation, is generally (i) responsible, directly or indirectly, for expenses attributable to the operation of the property, such as real estate taxes and assessments, insurance and ordinary maintenance and repairs, (ii) responsible for maintaining the property and, following a casualty or partial condemnation, for restoring the property, (iii) obligated to indemnify us for claims arising with respect to the property, and (iv) responsible for maintaining insurance coverage for the property and naming us an additional insured. Under some leases, we are responsible for structural repairs, including foundation and slab, roof repair or replacement and restoration following a casualty event, and at several properties we are responsible for certain expenses related to the operation and maintenance of the property.

Many of our leases provide for periodic contractual rent increases, rent increases based on the consumer price index or for additional payments based on sales derived from the property subject to the lease (i.e., percentage rent). Our leases generally provide the tenant with one or more renewal options. At December 31, 2025, 2024 and 2023, the weighted average remaining term of our leases was 4.4 years, 5.0 years and 5.5 years, respectively.

The following table sets forth scheduled expirations of leases at our properties as of December 31, 2025:

Table of Contents Financing, Re-Renting and Disposition of Our Properties

Our credit facility, which expires on December 31, 2026, provides us with a source of funds that is used to acquire properties, payoff existing mortgages, and to a more limited extent, invest in joint ventures, improve properties and for working capital purposes. Generally, net proceeds received from the sale, financing or refinancing of properties are required to be used to repay amounts outstanding under our facility. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Credit Facility”.

We mortgage specific properties on a non-recourse basis, subject to standard carve-outs, to enhance the return on our investment in a specific property. Generally, the proceeds of mortgage loans are first applied to reduce indebtedness on our credit facility and the balance may be used for other general purposes, including property acquisitions, investments in joint ventures or other entities that own real property, and working capital.

With respect to properties we acquire on a free and clear basis, we usually seek to obtain long-term fixed-rate mortgage financing, when available at acceptable terms, shortly after the acquisition of such property to avoid the risk of fluctuating (i) interest rates and (ii) supply and demand in the credit and mortgage markets. We also will acquire a property that is subject to (and will assume) a fixed-rate mortgage. Many of our mortgages provide for amortization of part of the principal balance during the term, thereby reducing the refinancing risk at maturity. Some properties are financed on a cross-defaulted or cross-collateralized basis, and we may collateralize a single financing with more than one property.

Prior to the termination or expiration of leases relating to our properties, we explore re-renting or selling such property to maximize our return, considering, among other factors, the income potential and market value of such property. We acquire properties for long-term investment for income purposes and do not typically engage in the turnover of investments. We will consider the sale of a property if a sale appears advantageous in view of our investment objectives. If there is a substantial tax gain, we may seek to enter into a tax deferred transaction and reinvest the proceeds in another property. Cash realized from the sale of properties, net of required payoffs of the related mortgage debt, if any, required paydowns of our credit facility, and distributions to stockholders, is available for general working capital purposes and the acquisition of additional properties.

In 2025, we sold ten properties (i.e., seven retail, a restaurant, a veterinary hospital and a property ground leased to a multi-unit apartment complex owner/operator). Generally, we sold these properties due to one or more of the following considerations: our belief that such property had achieved its maximum potential value; our concern with respect to the long-term prospects for the tenant or the geographic sub-market; our concern in our ability, on acceptable terms, to refinance the property’s mortgage debt or re-lease the property; or in furtherance of our efforts to decrease the number of our non-industrial properties and recycle the net proceeds therefrom such sales to expand our industrial portfolio.

Competition

The market for industrial properties in the United States is highly competitive; we compete to acquire industrial properties with, among others, traded and non-traded public REITs, private equity firms, institutional investment funds, insurance companies and private individuals, many of whom have greater financial and other resources than we have, and the ability or willingness to accept more risk than we believe appropriate for us. We can provide no assurance that we will be able to compete successfully in acquiring or leasing industrial properties.

Regulation

Environmental

Investments in real property create the potential for environmental liability on the part of the owner or operator of such real property. If hazardous substances are discovered on or emanating from a property, the owner or operator of the property may be held strictly liable for all costs and liabilities relating to such hazardous substances. We generally obtain a Phase I environmental study (which involves inspection without soil sampling 7

Table of Contents or ground water analysis) conducted by independent environmental consultants prior to acquiring a property and, in certain instances, have conducted additional investigations.

We do not believe that there are hazardous substances existing on our properties that would have a material adverse effect on our business, financial position or results of operations. We do not carry insurance coverage for the types of environmental risks described above.

We believe that we are in compliance, in all material respects, with all federal, state and local ordinances and regulations regarding hazardous or toxic substances. Furthermore, we have not been notified by any governmental authority of any noncompliance, liability or other claim in connection with any of our properties, that we believe would have a material adverse effect on our business, financial position or results of operations.

Our properties are required to comply with the Americans with Disabilities Act of 1990 and similar state and local laws and regulations (collectively, the “ADA”). The primary responsibility for complying with the ADA, (i.e., either us or our tenant) generally depends on the applicable lease, but we may incur costs if the tenant is responsible and does not comply. As of December 31, 2025, we have not been notified by any governmental authority, nor are we otherwise aware, of any non-compliance with the ADA that we believe would have a material adverse effect on our business, financial position or results of operations.

Other Regulations

State and local governmental authorities regulate the use of our properties. While many of our leases mandate that the tenant is primarily responsible for complying with such regulations, the tenant’s failure to comply could result in the imposition of fines or awards of damages on us, as the property owner, or restrictions on the ability to conduct business on such properties.

Human Capital Resources

As of December 31, 2025, we had nine full-time employees, including five full-time executive officers, and two employees who devote between 50% to 75% of their time to our activities. In addition, certain (i) executive, administrative, legal, accounting, clerical, property management, property acquisition, consulting (i.e., sale, leasing, brokerage, and mortgage financing), and construction supervisory services, which we refer to collectively as the “Services”, and (ii) facilities and other resources, are provided pursuant to a compensation and services agreement between us and Majestic Property.

In 2025, pursuant to the compensation and services agreement, we paid Majestic Property approximately $3.6 million for the Services plus $350,000 for our share of all direct office expenses, including rent, telephone, postage, computer services, internet usage and supplies. Included in the $3.6 million is $1.6 million for property management services—the amount for the property management services is based on 1.5% and 2.0% of the rental payments (including tenant reimbursements) actually received by us from net lease tenants and operating lease tenants, respectively. We do not pay Majestic Property for property management services with respect to properties managed by third parties. Based on our portfolio of properties at December 31, 2025, we estimate that the property management fee in 2026 will be approximately $1.7 million.

We provide a competitive benefits program to help meet the needs of our employees. In addition to salaries, the program includes annual cash bonuses, stock awards, contributions to a pension plan, healthcare and insurance benefits, health savings accounts, paid time off and family leave. Employees are given regular opportunities to participate in professional development programs, and we work with our employees to help them meet their personal and family needs. Most of our employees have a long tenure with us, which we believe is indicative of their satisfaction with our work environment.

Table of Contents Item 1A. Risk Factors.

Set forth below is a discussion of certain risks affecting our business. The categorization of risks set forth below is meant to help you better understand the risks facing our business and is not intended to limit your consideration of the possible effects of these risks to the listed categories. Any impacts from the realization of any of the risks discussed, including our financial condition and results of operations, may, and likely will, adversely affect many aspects of our business. In addition to the other information contained or incorporated by reference in this Form 10-K, readers should carefully consider the following risk factors:

Risks Related to Our Business

If we are unable to re-rent properties upon the expiration of our leases or if our tenants default or seek bankruptcy protection, our revenues and operating cash flows will be reduced and we would incur additional costs.

Substantially all of our revenue and operating cash flow is derived from rent paid by our tenants pursuant to leases. As of December 31, 2025, the following leases expire during the periods indicated:

Number of Percentage of
Leases Expiring December 31, Leases 2026 Base Rent 2026 Base Rent
2026 (a) 12 $ 2,567,000 3.1
2027 34 15,141,000 18.3
2028 24 13,228,000 16.0
2029 20 11,792,000 14.3
2030 25 12,606,000 15.2
2031 15 9,160,000 11.1

(a)We believe or have been advised that tenants with respect to three leases, or $553,000 of 2026 base rent, intend to allow their leases to expire.

If our tenants, and in particular, our significant tenants, (i) do not renew their leases upon lease expiration, (ii) default on their obligations or (iii) seek rent relief, lease renegotiation or other accommodations, our revenues would decline and, in certain cases, co-tenancy provisions (i.e., a tenant’s right to reduce their rent or terminate their lease if certain key tenants vacate a property) may be triggered possibly allowing other tenants at the same property to reduce their rental payments or terminate their leases. At the same time, we would remain responsible (and with respect to single tenant properties (i.e., properties at which such tenant is the sole lessee) solely responsible), for the payment of the mortgage obligations with respect to the related properties, would become responsible for the operating expenses (e.g., real estate taxes, maintenance and insurance) related to these properties, and, in the event of tenant defaults, would incur expenses in enforcing our rights as landlord. We may find it difficult to find replacement tenants, especially with respect to properties that have unusual configurations, such as our theaters (i.e., Regal Cinemas) and a health and fitness center (i.e., LA Fitness) which account in the aggregate for $2.2 million, or 2.7%, of 2026 base rent. Even if we find replacement tenants or renegotiate leases with current tenants, the terms of the new or renegotiated leases, after giving effect to tenant concessions or the cost of required renovations/reconfigurations may be less favorable than current lease terms and could reduce the amount of cash available to meet expenses and pay dividends. If we are unable to re-rent properties on favorable terms with respect to properties at which tenants do not renew their leases at lease expiration or default on their rent obligation, and our results of operations, cash flow and financial condition will be adversely affected.

Approximately 21.7% of our 2026 base rent is derived from six tenants. The default, financial distress or failure of any of these tenants, or such tenant’s determination not to renew or extend their lease, would significantly reduce our revenues.

FedEx, Northern Tool, NARDA Holdings, Inc., Havertys, Ferguson and Toro Company account for approximately 5.0%, 3.8%, 3.7%, 3.1%, 3.1% and 3.0%, respectively, of our 2026 base rent, and the weighted average remaining lease term for such tenants is 2.2 years, 3.3 years, 7.7 years, 3.0 years, 1.6 years and 3.0 years, respectively. The default, financial distress or bankruptcy of any of these or other significant tenants or such tenant’s determination not to renew or extend their lease, would significantly reduce our revenues, would cause 10

Table of Contents interruptions in the receipt of, or the loss of, a significant amount of rental income and would require us to pay operating expenses (including real estate taxes) currently paid by the tenant. This could also result in the vacancy of the property or properties occupied by the defaulting or non-renewing tenant, which would significantly reduce our rental revenues and net income until the re-rental of the property or properties and could decrease the ultimate sale value of the property.

The concentration of our properties in certain states makes our revenues and the value of our portfolio vulnerable to adverse changes in local economic conditions.

Approximately 51.5% of our 2026 base rent is derived from properties located in six states — South Carolina (12.8%), Pennsylvania (10.8%), New York (8.5%), Texas (7.1%), Iowa (6.6%) and Alabama (5.7%). As a result, a decline in the economic conditions in these states or in regions where our properties are concentrated, may have an adverse effect on the rental and occupancy rates for, and the property values of, these properties, which could lead to a reduction of our rental income and/or impairment charges.

Our portfolio of properties is concentrated in the industrial and, to a lesser extent, the retail sector, and our business would be adversely affected by an economic downturn in such sectors.

Approximately 80.9% and 14.6% of our 2026 base rent is derived from industrial and retail tenants, respectively, and we are vulnerable to economic declines that negatively impact these sectors of the economy, which would have an adverse effect on our results of operations, liquidity and financial condition.

Write-offs of unbilled rent receivables and intangible lease assets will reduce our net income, total assets and stockholders’ equity and may result in breaches of financial covenants under our credit facility.

At December 31, 2025, the aggregate of our unbilled rent receivable and intangible lease assets is $42.8 million (including $25.5 million of intangible lease assets): six tenants (i.e., NARDA Holdings, Inc., Superior Third Party Logistics, Inc., The Lion Brewery, Charter Next Generation, Inc., Northern Tool, and Famous Footwear) account for 27.5% of such sum. We are required to assess the collectability of our unbilled rent receivables and the remaining useful lives of our intangible lease assets. Such assessments, which are highly subjective, take into consideration, among other things, a tenant’s payment history, financial condition, and the likelihood of collectability of future rent.  If we determine that the collectability of a tenant’s unbilled rent receivable is not probable or that the useful life of a tenant’s intangible lease asset has changed, write-offs would be required.  Such write-offs result in a reduction of our net income, total assets and stockholders’ equity and in certain circumstances may result in the breach of our financial covenants under the credit facility.

Declines in the value of our properties could result in impairment losses.

When we are presented with indicators of impairment in the value of a particular property or group of properties, we are required to perform an impairment analysis for such property or properties. When we determine that any of our properties at which indicators of impairment exist have undiscounted cash flows below the net book value of such property, we are required to recognize an impairment charge for the difference between the fair value and the book value during the quarter in which we make such determination. Impairment losses, such as the impairment losses of $4.6 million and $1.1 million we recognized in 2025 and 2024, respectively, reduce our total assets, stockholder’s equity and net income.

Our ability to fully control the maintenance of our properties may be limited.

Generally, the tenants are responsible for maintenance and other day-to-day management of the properties. If a property is not adequately maintained in accordance with the terms of the applicable lease, we may incur expenses for deferred maintenance or other liabilities once the property is no longer leased. While we visit our properties on an intermittent basis, these visits are not comprehensive inspections and deferred maintenance items may go unnoticed. Although our leases generally provide for recourse against the tenant for failure to maintain the property, a bankrupt or financially-troubled tenant may be more likely to defer maintenance, and it may be difficult to recover the cost of such repairs from such a tenant. 11

Table of Contents Traditional retail tenants account for 14.6% of our 2026 base rent and the competition that such tenants face from e-commerce retail sales could adversely affect our business.

Approximately 14.6% of our 2026 base rent is derived from retail tenants, including 3.8% from tenants engaged in selling furniture (i.e., Havertys Furniture accounts for 3.1% of 2026 base rent). Because e-commerce retailers (unlike “bricks and mortar” or “traditional” retailers) may be able to provide customers with better pricing and the ease, comfort and safety of shopping from their home or office, our retail tenants face extensive competition from e-commerce retailers. E-commerce sales decrease the need for traditional retail outlets and reduce retailers’ space and property requirements. This adversely impacts our ability to rent space at our retail properties and increases competition for retail tenants thereby reducing the rent we would receive at these properties and adversely affecting our results of operations, cash flow and financial condition.

Risks Related to Our Financing Activities, Indebtedness and Capital Resources

If we are unable to refinance our mortgage loans at maturity, we may be forced to sell properties at disadvantageous terms, which would result in the loss of revenues and in a decline in the value of our portfolio.

We had, as of December 31, 2025, $522.5 million in mortgage debt outstanding (all of which is non-recourse subject to standard carve-outs). The risks associated with our mortgage debt, include the risks that cash flow from properties securing the indebtedness and our available cash and cash equivalents will be insufficient to meet required payments of principal and interest.

Generally, only a portion of the principal of our mortgage indebtedness will be repaid prior to or at maturity and we do not plan to retain sufficient cash to repay such indebtedness at maturity. Accordingly, to meet these obligations if they cannot be refinanced at maturity, we will have to use funds available under our credit facility, if any, and our available cash and cash equivalents to pay our mortgage debt or seek to raise funds through the financing of unencumbered properties, sale of properties or the issuance of additional equity. From 2026 through 2030, approximately $237.3 million of mortgage debt outstanding as of December 31, 2025, matures. Our cash flow from operations will be insufficient to repay all maturing mortgage debt when payments become due, and we may be forced to dispose of properties on disadvantageous terms or convey properties secured by mortgages to the mortgagees, which would lower our revenues and the value of our portfolio.

We may find that the value of a property could be less than the mortgage secured by such property. We may also have to decide whether we should refinance or pay off a mortgage on a property at which the mortgage matures prior to lease expiration and the tenant may not renew the lease. In these types of situations, after evaluating various factors, including among other things, the tenant’s competitive position in the applicable sub-market, our and our tenant’s estimates of its prospects, consideration of alternative uses and opportunities to re-purpose or re-let the property, we may seek to renegotiate the terms of the mortgage, or to the extent that the loan is non-recourse and the terms of the mortgage cannot be satisfactorily renegotiated, forfeit the property by conveying it to the mortgagee and writing off our investment.

Volatile or increasing interest rates, or credit market tightening, may make it more difficult for us to secure financing, which may limit our ability to finance or refinance our real estate properties, reduce the number of properties we can acquire, sell certain properties, and decrease our stock price.

Increases or volatility in interest rates, or reduced access to credit markets, may make it difficult for us to obtain financing, refinance mortgage debt, limit the mortgage debt available on properties we wish to acquire and limit the properties we can acquire. Even in the event that we are able to secure mortgage debt on, or otherwise finance our real estate properties, due to increased costs associated with securing financing and other factors beyond our control, we may be unable to refinance the entire outstanding loan balance or be subject to unfavorable terms (such as higher loan fees, interest rates and periodic payments). In addition, increasing interest rates could decrease the amount third parties are willing to pay for our assets, thereby limiting our ability to dispose of assets on more favorable terms. 12

Table of Contents Interest rates have been volatile as the interest rate on the ten-year treasury notes ranged from 3.26% to 5.02% during the three years ended December 31, 2025. At February 27, 2026, the interest rate on such notes was 3.95%. The following table sets forth, as of December 31, 2025, the principal balance of the mortgage payments due at maturity on our properties and the weighted average interest rate thereon (dollars in thousands):

​ ​ ​ Principal ​ ​ ​
Balances Weighted Average
Due at Interest Rate
Year Maturity Percentage
2026 $ 17,767 3.93
2027 38,525 3.64
2028 30,155 4.64
2029 79,386 4.41
2030 71,429 5.43
2031 and thereafter 215,245 5.32

If we are required to refinance mortgage debt that matures over the next several years at higher interest rates than such mortgage debt currently bears, our net income will decline and the funds available for dividends will be reduced.

Because REIT stocks are often perceived as high-yield investments, investors may perceive less relative benefit to owning REIT stocks as interest rates and the yield on government treasuries and other bonds increase or are especially volatile. Accordingly, increases and volatility in interest rates may reduce the amount investors are willing to pay for our common stock.

A breach of our credit facility could occur if a significant number of our tenants default or fail to renew expiring leases, or we take impairment charges against our properties.

Our credit facility includes covenants that require us to maintain certain financial ratios and comply with other requirements. If our tenants default under their leases or fail to renew expiring leases, we may recognize impairment charges against our properties, and our financial position could be adversely affected causing us to be in breach of the financial covenants contained in our credit facility.

Failure to meet interest and other payment obligations under our revolving credit facility or a breach by us of the covenants to maintain the financial ratios could place us in default under our credit facility. In such event, if no amounts were outstanding under the facility, we would not be entitled to draw on the facility which could impede our ability, among other things, to acquire properties or fund working capital requirements. If we defaulted on the facility while amounts were outstanding, the lenders could require us to repay the full amount outstanding, and we might be required to rapidly dispose of our properties, which could have an adverse impact on the amounts we receive on such dispositions. If we are unable to dispose of our properties in a timely fashion to the satisfaction of the banks, the banks could foreclose on that portion of our collateral pledged to the banks, which could result in the disposition of our properties at below-market values. The disposition of our properties at below our carrying value would adversely affect our net income, reduce our stockholders’ equity and adversely affect our ability to pay dividends.

If we are unable to renew or replace our credit facility which expires on December 31, 2026, we will be adversely affected as we will be limited in our ability to acquire properties and will be forced to immediately repay the debt outstanding thereunder.

At February 27, 2026, $30.0 million was outstanding on our credit facility. The facility expires on December 31, 2026 at which time we will be obligated, unless the facility is renewed or replaced, to repay all amounts outstanding thereunder. We will not have sufficient cash to repay the facility at such time and would be forced to sell properties or find alternative sources of funding, potentially on disadvantageous terms, to fund the repayment of such obligations. Further, the facility enhances our ability to acquire properties on an expedited basis; the unavailability of the facility or a similar source of immediately available funds would limit our ability to acquire properties. 13

Table of Contents Certain of our leases require us to pay property related expenses that are not the obligations of our tenants.

In addition to satisfying their rent obligations, our tenants are generally responsible for the payment of real estate taxes, insurance and ordinary maintenance and repairs. However, under the provisions of certain leases, we are required to pay some expenses, such as the costs of environmental liabilities, roof and structural repairs, insurance premiums, and certain non-structural repairs and maintenance. If our properties incur significant expenses that must be paid by us under the terms of our leases, our business, financial condition and results of operations will be adversely affected and the amount of cash available to meet expenses and pay dividends may be reduced.

Our failure to comply with our obligations under our mortgages may reduce our stockholders’ equity, and adversely affect our net income and ability to pay dividends.

Several of our mortgages include covenants that require us to maintain certain financial ratios, including various coverage ratios, and comply with other requirements. Failure to meet interest and other payment obligations under these mortgages or a breach by us of the covenants to comply with certain financial ratios would place us in non-compliance under such mortgages. If a mortgagee called a default and required us to repay the full amount outstanding under such mortgage, we might be required to rapidly dispose of the property subject to such mortgage which could have an adverse impact on the amounts we receive on such disposition. If we are unable to satisfy the covenants of a mortgage, the mortgagee could exercise remedies available to it under the applicable mortgage and as otherwise provided by law, including the possible appointment of a receiver to manage the property, application of deposits or reserves maintained under the mortgage for payment of the debt, or foreclose and/or cause the forced sale of the property or asset securing such debt. A foreclosure or other forced disposition of our assets could result in the disposition of such assets at below such assets’ carrying values. The disposition of our properties or assets at below their carrying values may adversely affect our net income, reduce our stockholders’ equity and adversely affect our ability to pay dividends.

Risks Related to Real Estate Investments

Our revenues and the value of our portfolio are affected by a number of factors that affect investments in leased real estate generally.

We are subject to the general risks of investing in leased real estate. These include the non-performance of lease obligations by tenants, leasehold improvements that will be costly or difficult to remove should it become necessary to re-rent the leased space for other uses, covenants in certain retail leases that limit the types of tenants to which available space can be rented (which may limit demand or reduce the rents realized on re-renting), rights to terminate leases due to co-tenancy provisions, events of casualty or condemnation affecting the leased space or the property or due to interruption of the tenant’s quiet enjoyment of the leased premises, obligations of a landlord to restore the leased premises or the property following events of casualty or condemnation, adverse changes in economic conditions and local conditions (e.g., changing demographics, retailing trends and traffic patterns), declines in rental rates, changes in the supply and price of quality properties and the market supply and demand of competing properties, the impact of environmental laws, security concerns, prepayment penalties applicable under mortgage financings, changes in tax, zoning, building code, fire safety and other laws and regulations, the type of insurance coverage available, and changes in the type, capacity and sophistication of building systems. The occurrence of any of these events could adversely impact our results of operations, liquidity and financial condition.

Real estate investments are relatively illiquid and their values may decline.

Real estate investments are relatively illiquid. Therefore, we will be limited in our ability to reconfigure our real estate portfolio in response to economic changes. We may encounter difficulty in disposing of properties when tenants vacate either at the expiration of the applicable lease or otherwise. If we decide to sell any of our properties, our ability to sell these properties and the prices we receive on their sale may be affected by many factors, including the number of potential buyers, the number of competing properties on the market and other market conditions, as well as whether the property is leased and if it is leased, the terms thereof. As a result, we may be unable to sell our properties for an extended period of time without incurring a loss, which would adversely affect our results of operations, liquidity and financial condition. 14

Table of Contents Uninsured and underinsured losses may affect the revenues generated by, the value of, and the return from a property affected by a casualty or other claim.

Generally, our tenants’ are required to obtain, for our benefit, comprehensive insurance covering our properties in amounts that are intended to be sufficient to provide for the replacement of the improvements at each property. However, the amount of insurance coverage maintained for any property may be insufficient (i) to pay the full replacement cost of the improvements at the property following a casualty event or (ii) if coverage is provided pursuant to a blanket policy and the tenant’s other properties are subject to insurance claims. In addition, the rent loss coverage under the policy may not extend for the full period of time that a tenant may be entitled to a rent abatement as a result of, or that may be required to complete restoration following, a casualty event. In addition, there are certain types of losses, such as those arising from earthquakes, floods, hurricanes and terrorist attacks, that may be uninsurable or that may not be economically insurable. Changes in zoning, building codes and ordinances, environmental considerations and other factors also may make it impossible or impracticable for us to use insurance proceeds to replace damaged or destroyed improvements at a property. If restoration is not or cannot be completed to the extent, or within the period of time, specified in certain of our leases, the tenant may have the right to terminate the lease. If any of these or similar events occur, it may reduce our revenues, the value of, or our return from, an affected property.

We have been, and will continue to be, subject to significant competition and we may not be able to compete successfully for investments.

We have faced, and will continue to face, significant competition for opportunities to acquire industrial properties. Our competitors include publicly-traded REITs, non-traded REITs, insurance companies, commercial and investment banking firms, private institutional funds, hedge funds, private equity funds and other investors, many of whom have greater financial and other resources than we have. We may not be able to compete successfully for investments. If we pay higher prices for investments, our returns may be lower and the value of our assets may not increase or may decrease significantly below the amount we paid for such assets. If such events occur, we may experience lower returns on our investments.

Regulatory and Tax Risks

Compliance with environmental regulations and associated costs could adversely affect our results of operations and liquidity.

Under various federal, state and local laws, ordinances and regulations, an owner or operator of real property may be required to investigate and clean up hazardous or toxic substances or petroleum product releases at the property and may be held liable to a governmental entity or to third parties for property damage and for investigation and cleanup costs incurred in connection with contamination. The cost of investigation, remediation or removal of hazardous or toxic substances may be substantial, and the presence of such substances, or the failure to properly remediate a property, may adversely affect our ability to sell or rent the property or to borrow money using the property as collateral. In connection with our ownership, operation and management of real properties, we may be considered an owner or operator of the properties and, therefore, potentially liable for removal or remediation costs, as well as certain other related costs, including governmental fines and liability for injuries to persons and property, not only with respect to properties we own now or may acquire, but also with respect to properties we have owned in the past.

We cannot provide any assurance that existing environmental studies with respect to any of our properties reveal all potential environmental liabilities, that any prior owner of a property did not create any material environmental condition not known to us, or that a material environmental condition does not otherwise exist, or may not exist in the future, as to any one or more of our properties. If a material environmental condition does in fact exist, or exists in the future, the remediation costs could have a material adverse impact upon our results of operations, liquidity and financial condition. 15

Table of Contents Compliance with the Americans with Disabilities Act could be costly.

Under the Americans with Disabilities Act of 1990 (the “ADA”), all public accommodations must meet Federal requirements for access and use by disabled persons. A determination that our properties do not comply with the ADA could result in liability for both governmental fines and damages. If we are required to make unanticipated major modifications to any of our properties to comply with the ADA, which are determined not to be the responsibility of our tenants, we could incur unanticipated expenses that could have an adverse impact upon our results of operations, liquidity and financial condition.

Legislative or regulatory tax changes could have an adverse effect on us.

There are a number of issues associated with an investment in a REIT that are related to the Federal income tax laws, including, but not limited to, the consequences of our failing to continue to qualify as a REIT. At any time, the Federal income tax laws governing REITs or the administrative interpretations of those laws may be amended or modified. Any new laws or interpretations may take effect retroactively and could adversely affect us or our stockholders.

Risks Related to OLP’s Organization, Structure and Ownership of Stock

Our transactions with affiliated entities involve conflicts of interest.

From time to time we have entered into transactions with persons and entities affiliated with us and with certain of our officers and directors. Such transactions involve a potential conflict of interest and entail a risk that we could have obtained more favorable terms if we had entered into such transaction with an unaffiliated third party. We are a party to a compensation and services agreement with Majestic Property effective as of January 1, 2007, as amended. Pursuant to the compensation and services agreement, we pay an annual fee to Majestic Property which provides us with the Services. See “Item 1. BusinessHuman Capital Resources”. In 2025 we paid, and in 2026 we anticipate paying, Majestic Property, (i) a fee of $3.6 million and $3.8 million, respectively, and (ii) $350,000 and $368,000, respectively, for our share of all direct office expenses, including rent, telephone, postage, computer services, supplies, and internet usage. We also obtain our property insurance in conjunction with Gould Investors, an affiliated entity, and in 2025, reimbursed Gould Investors $3.0 million for our share of the insurance premiums paid by Gould Investors. At December 31, 2025, Gould Investors beneficially owns approximately 10.5% of our outstanding common stock and certain of our senior executive officers are also executive officers of the managing general partner of Gould Investors.

Our senior management and other key personnel, including those performing services on a part-time basis, are critical to our business and our future success depends on our ability to retain them.

We depend on the services of Matthew J. Gould, chairman of our board of directors, Fredric H. Gould, vice chairman of our board of directors, Patrick J. Callan, Jr., our president and chief executive officer, Lawrence G. Ricketts, Jr., our executive vice president and chief operating officer, Isaac Kalish, our chief financial officer and senior vice president and David W. Kalish, our senior vice president-finance, and other members of senior management to carry out our business and investment strategies. Of the foregoing executive officers, only Messrs. Callan and Ricketts devote all of their business time to us. Other members of senior management provide services to us either on a full-time or part-time, as-needed basis. The loss of the services of any of our senior management or other key personnel, the inability or failure of the members of senior management providing services to us on a part-time basis to devote sufficient time or attention to our activities or our inability to recruit and retain qualified personnel in the future, could impair our ability to carry out our business and investment strategies. 16

Table of Contents Certain provisions of our charter, our Bylaws, as amended, and Maryland law may inhibit a change in control that stockholders consider favorable and could also limit the market price of our common stock.

Certain provisions of our charter (the “Charter”), our Bylaws and Maryland law may impede, or prevent, a third party from acquiring control of us without the approval of our board of directors. These provisions:

provide for a staggered board of directors consisting of three classes, with one class of directors being elected each year and each class being elected for three-year terms and until their successors are duly elected and qualify;
impose restrictions on ownership and transfer of our stock (such provisions being intended to, among other purposes, facilitate our compliance with certain requirements under the Code, relating to our qualification as a REIT under the Code); and
--- ---
provide that directors may be removed only for cause and only by the vote of at least a majority of all outstanding shares entitled to vote.
--- ---

Certain provisions of the Maryland General Corporation Law (the “MGCL”) may impede a third party from making a proposal to acquire us or inhibit a change of control under circumstances that otherwise could be in the best interest of holders of shares of our common stock, including:

“control share” provisions that provide that, subject to certain exceptions, holders of “control shares” of our company (defined as voting shares which, when aggregated with other shares controlled by the stockholder, entitle the holder to exercise voting power in the election of directors within one of three increasing ranges) acquired in a “control share acquisition” (defined as the direct or indirect acquisition of ownership or control of issued and outstanding “control shares,” subject to certain exceptions) have no voting rights with respect to the control shares except to the extent approved by our stockholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares; and
additionally, Title 3, Subtitle 8 of the MGCL permits our board of directors, without stockholder approval and regardless of what is currently provided in the Charter or the Bylaws, to implement certain corporate governance provisions.
--- ---

Failure to qualify as a REIT could result in material adverse tax consequences and could significantly reduce cash available for distributions.

We operate so as to qualify as a REIT under the Code. Qualification as a REIT involves the application of technical and complex legal provisions for which there are limited judicial and administrative interpretations. The determination of various factual matters and circumstances not entirely within our control may affect our ability to qualify as a REIT. In addition, no assurance can be given that legislation, new regulations, administrative interpretations or court decisions will not significantly change the tax laws with respect to qualification as a REIT or the federal income tax consequences of such qualification. If we fail to quality as a REIT, we will be subject to federal, certain additional state and local income tax (including any applicable alternative minimum tax) on our taxable income at regular corporate rates and would not be allowed a deduction in computing our taxable income for amounts distributed to stockholders. In addition, unless entitled to relief under certain statutory provisions, we would be disqualified from treatment as a REIT for the four taxable years following the year during which qualification is lost. The additional tax would reduce significantly our net income and the cash available to pay dividends. 17

Table of Contents We are subject to certain distribution requirements that may result in our having to borrow funds at unfavorable rates.

To obtain the favorable tax treatment associated with being a REIT, we generally are required, among other things, to distribute to our stockholders at least 90% of our ordinary taxable income (subject to certain adjustments) each year. To the extent that we satisfy these distribution requirements but distribute less than 100% of our taxable income we will be subject to Federal and state corporate tax on our undistributed taxable income.

As a result of differences in timing between the receipt of income and the payment of expenses, and the inclusion of such income and the deduction of such expenses in arriving at taxable income, and the effect of nondeductible capital expenditures and the timing of required debt service (including amortization) payments, we may need to borrow funds in order to make the distributions necessary to retain the tax benefits associated with qualifying as a REIT, even if we believe that then prevailing market conditions are not generally favorable for such borrowings. Such borrowings could reduce our net income and the cash available to pay dividends.

Compliance with REIT requirements may hinder our ability to maximize profits.

In order to qualify as a REIT for Federal income tax purposes, we must continually satisfy tests concerning, among other things, our sources of income, the amounts we distribute to our stockholders and the ownership of our stock. We may also be required to make distributions to stockholders at disadvantageous times or when we do not have funds readily available for distribution. Accordingly, compliance with REIT requirements hinders our ability to operate solely on the basis of maximizing profits.

In order to qualify as a REIT, we must also ensure that at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and real estate assets. Any investment in securities cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, no more than 5% of the value of our assets can consist of the securities of any one issuer, other than a qualified REIT security. If we fail to comply with these requirements, we must dispose of such portion of these securities in excess of these percentages within 30 days after the end of the calendar quarter in order to avoid losing our REIT status and suffering adverse tax consequences. This requirement could cause us to dispose of assets for consideration that is less than their true value and could lead to an adverse impact on our results of operations and financial condition.

If we reduce or do not increase our dividend, the market value of our common stock may decline.

The dividends we pay are determined by our board of directors from time-to-time based on its assessment of, among other things, our short and long-term cash and liquidity requirements, prospects, debt maturities, maintenance of our REIT status, projections of our REIT taxable income, net income, funds from operations and adjusted funds from operations. Various factors could cause our board of directors to decrease or not increase our dividend, including tenant defaults or bankruptcies resulting in a material reduction in our funds from operations, a material loss resulting from an adverse change in the value of one or more of our properties, or insufficient income to cover our dividends. It is possible that a portion of the dividends we would pay in 2025 or thereafter would constitute a return of capital and in such event we would not be required to pay such sum to maintain our REIT status. If our board of directors determines to reduce or not increase our dividend for the foregoing or any other reason, the market value of our common stock could be adversely affected.

The stock market is volatile, and fluctuations in our operating results, removal from various indices and other factors could cause our stock price to decline.

The stock market has experienced, and may continue to experience, fluctuations that significantly impact the market prices of securities issued by many companies. Market fluctuations could adversely affect our stock price. These fluctuations have often been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations, as well as general economic, systemic, political and market conditions, such as pandemics, recessions, loss of investor confidence, interest rate changes, government shutdowns, or trade wars, may negatively affect the market price of our common stock. Moreover, our operating results may fluctuate and vary from period to period due to the risk factors set forth herein. 18

Table of Contents Although our common stock is quoted on the New York Stock Exchange, the volume of trades on any given day has been limited historically, as a result of which stockholders might not have been able to sell or purchase our common stock at the volume, price or time desired. Further, if our common stock is removed from the Russell 3000® Index because it does not meet the criteria for continued inclusion in such index, index funds, institutional investors, or other holders attempting to track the composition of that index may be required to sell our common stock, which would adversely impact the price and frequency at which it trades.

General Business Risks

Enhanced market and economic volatility due to adverse economic and geopolitical conditions, health crises or dislocations in the credit markets, could have a material adverse effect on our results of operations, financial condition and ability to pay dividends.

Our business may be adversely affected by market and economic volatility experienced by the U.S. and global economies, the real estate industry as a whole and/or the local economies in the markets in which our properties are located. Such adverse conditions may be due to, among other issues, rising inflation and interest rates, volatility in the public equity and debt markets, labor market challenges and international economic and other conditions, including pandemics, geopolitical instability, sanctions and other conditions beyond our control. These current conditions, or similar conditions existing in the future, may adversely affect our results of operations, financial condition and ability to pay dividends as a result of one or more of the following, among other potential consequences:

the financial condition of our tenants may be adversely affected, which may result in lower rents or tenant defaults;
current or potential tenants may delay or postpone entering into long-term net leases with us;
--- ---
the ability to borrow on acceptable terms and conditions may be limited or unavailable, which could reduce our ability to pursue acquisitions, dispositions and refinance existing debt, reduce our returns from acquisition and disposition activities, increase our future interest expense and reduce our ability to make cash distributions to our stockholders;
--- ---
our ability to access the capital markets may be restricted at a time when we would like, or need, to access those markets, which could have an impact on our flexibility to react to changing economic and business conditions;
--- ---
the recognition of impairment charges on or reduced values of our properties, which may adversely affect our results of operations or limit our ability to dispose of assets at attractive prices and may reduce the availability of financing;
--- ---
our line of credit lenders could refuse to fund their financing commitment to us, or could fail, and we may not be able to replace the financing commitment of any such lenders on favorable terms, or at all; and
--- ---
one or more counterparties to our derivative financial instruments could default on their obligations to us, or could fail, increasing the risk that we may not realize the benefits of these instruments.
--- ---

Breaches of information technology systems could materially harm our business and reputation.

We collect and retain on information technology systems, certain financial, personal and other sensitive information provided by third parties, including tenants, vendors, employees and joint venture partners. We also rely on information technology systems for the collection and distribution of funds. We have been, and continue to be, subject to cybersecurity attacks although we have not incurred any significant loss therefrom. There can be no assurance that we will be able to prevent unauthorized access to sensitive information or the unauthorized distribution of funds. Any loss of this information or unauthorized distribution of funds as a result of a cybersecurity attack may result in loss of funds to which we are entitled, legal liability and costs (including damages and penalties), as well as damage to our reputation, that could materially and adversely affect our business. 19

Table of Contents

Artificial intelligence and other machine learning techniques could increase competitive, operational, legal and regulatory risks to our business in ways that we cannot predict.

The use of artificial intelligence (“AI”) by us and others, and the overall adoption of AI throughout society, may exacerbate or create new and unpredictable competitive, operational, legal and regulatory risks to our business. There is substantial uncertainty about the extent to which AI will result in dramatic changes throughout the world, and we may not be able to anticipate, prevent, mitigate or remediate all of the potential risks, challenges or impacts of such changes. These changes could potentially disrupt, among other things, our business and operational processes. Our competitors may be more successful than us in the development and implementation of services and platforms based on AI to improve their operations. If we are unable to adequately use AI, or do so at a slower pace than others in our industry, we will be at a competitive disadvantage.

If the data we, or third parties whose services we rely on and over whom we have limited oversight, use in connection with the possible development or deployment of AI is incomplete, inadequate or biased in some way, the performance of our business could suffer. Data in technology that uses AI may contain a degree of inaccuracy and error, which could result in flawed decision-making on our part and other service providers. This could reduce the effectiveness of AI technologies and adversely impact us and our operations to the extent that we rely on the AI's work product. There is also a risk that we or our service providers may improperly disclose confidential information, including material non-public information or personally identifiable information, into AI applications, resulting in such information becoming a part of a dataset that is accessible by third parties.

Our and our service providers use of AI may require compliance with legal or regulatory frameworks that are not fully developed or tested, and we may face litigation and regulatory actions related to our or our service providers use of AI.

Actual or threatened epidemics, pandemics, outbreaks, or other public health crises may adversely affect our tenants’ financial condition and the profitability of our properties.

Our business and the businesses of our tenants could be materially and adversely affected by the risks, or the public perception of the risks, related to an epidemic, pandemic, outbreak, or other public health crisis, such as the COVID-19 pandemic. A severe public health crisis could disrupt our business and materially adversely affect our financial condition, results of operations and ability to pay distributions to our stockholders. Further, the impact of a widespread public health emergency may have the effect of exacerbating many of the other risks described in this Annual Report.

We are dependent on third party software for our financial reporting processes and systems.

We are dependent on third party software, and in particular, Yardi’s property management software, for generating tenant invoices, collecting receivables, paying payables and preparing financial reports. If the software does not perform as required (including non-performance resulting from the software vendors’ unwillingness or inability to maintain or upgrade the functionality of the software), our ability to conduct operations would be adversely affected.

None.

Item 1C. Cybersecurity.

Our information technology, communication networks, enterprise applications, accounting and financial reporting platforms and related systems are integral to our operations. We use these systems, among others, for internal communications, for accounting and record-keeping functions, and for many other key aspects of our business. Our operations rely on securing, collecting, storing, transmitting, and processing proprietary and confidential data.

We have deployed various safeguards designed to protect our information technology (“IT”) systems from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality and access controls. At the management level, these cybersecurity defense systems are overseen by our network administrator who performs services for us on a part-time basis pursuant to the compensation and services agreement. Our network administrator has more than 20 years of experience with IT systems and holds various IT certifications. Our network administrator reports to, and is in regular contact with, our Chief Financial Officer and Senior Vice President-Finance. These officers do not have formal IT or cybersecurity training. In the event of a cybersecurity incident, among other things, the network administrator and these officers would consult with one another and, as needed or appropriate, other members of management to determine the appropriate course of action (including whether such incident should be reported to other members of management and/or the audit committee and whether public disclosure should, or is required to, be made).

Our internal auditor performs certain procedures to test the integrity and functionality of our IT systems (which includes a high-level review of our cybersecurity defenses). In addition, we have retained a third-party cybersecurity consulting firm that (i) advises us as to cybersecurity matters (including prevailing cybersecurity threats), (ii) performs, on a periodic basis, assessments of our cybersecurity defenses and (iii) on a continuous basis, monitors our IT systems for cybersecurity threats and intrusions.

We are not aware of any risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect us. See “Item 1A. Risk Factors” in this Annual Report for additional discussions about cybersecurity-related risks.

To operate our business, we use certain third-party service providers to perform a variety of functions. We seek to engage reliable, reputable service providers that maintain cybersecurity programs and we rely on such providers to maintain appropriate cybersecurity practices.

At the Board level, our cybersecurity practices are overseen by the audit committee as part of its oversight of our risk management activities. The committee meets periodically with, among others, our internal auditor and network administrator to review and discuss cybersecurity matters. 21

Our common stock is listed on the New York Stock Exchange under the symbol “OLP.” As of February 27, 2026, there were approximately 225 holders of record of our common stock.

We qualify as a REIT for Federal income tax purposes. In order to maintain that status, we are required to distribute to our stockholders at least 90% of our annual ordinary taxable income. The amount and timing of future distributions will be at the discretion of our board of directors and will depend upon our financial condition, earnings, business plan, cash flow and other factors. We intend to make distributions in an amount at least equal to that necessary for us to maintain our status as a real estate investment trust for Federal income tax purposes.

Issuer Purchases of Equity Securities

As of February 27, 2026, we are authorized to repurchase up to $8.1 million of shares of our common stock through, among other things, open-market or privately negotiated transactions. There is no stated expiration date for our stock repurchase program. We did not repurchase any shares of our common stock in 2025.

Table of Contents Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview

We are a self-administered and self-managed REIT focused on acquiring, owning and managing a geographically diversified portfolio consisting primarily of industrial properties. As of February 1, 2026 and after giving effect to the ten industrial properties we acquired in January 2026, we own 113 properties with approximately 12.5 million square feet, including 79 industrial properties with approximately 11.0 million square feet, and we anticipate that our industrial properties will generate approximately 81.6% of our 2026 base rent.

General Challenges and Uncertainties

In addition to the challenges and uncertainties described under “Cautionary Note Regarding Forward-Looking Statements”, and “Item 1A. Risk Factors”, we, among other things, face additional challenges and uncertainties, including the possibility we will not be able to: lease our properties on terms favorable to us or at all; collect amounts owed to us by our tenants; renew or re-let, on acceptable terms, leases that are expiring or otherwise terminating; acquire or dispose of properties on acceptable terms; or grow, through acquisitions or otherwise, our property portfolio so as to generate additional rental and net income. If we are unable to address these challenges successfully, we may be unable to sustain our current level of dividend payments.

Other than with respect to our continuing focus on acquiring industrial properties, we generally seek to manage the risk of our real property portfolio and the related financing arrangements by (i) diversifying among locations, tenants, scheduled lease expirations, mortgage maturities and lenders, and (ii) minimizing our exposure to interest rate fluctuations. As a result, as of December 31, 2025:

our 2026 base rent is derived from the following property types: 80.9% from industrial, 14.6% from retail and 4.5% from other properties,
there are two states with properties that account for more than 10% of 2026 base rent (i.e., South Carolina at 12.8% and Pennsylvania at 10.8%) and six states with properties that account for 5% or more of 2026 base rent,
--- ---
there is one tenant at five properties that accounts for 5% of 2026 base rent (i.e., FedEx at 5%),
--- ---
the weighted average remaining term on our leases is 4.4 years,
--- ---
the percentage of our 2026 base rent represented by expiring leases equals or exceeds 10% for each of 2027 through 2031 (i.e., 18.3% in 2027, 16.0% in 2028, 14.3% in 2029, 15.2% in 2030 and 11.1% in 2031),
--- ---
the weighted average remaining term to maturity of our mortgage debt is 5.8 years and the weighted average interest rate thereon is 4.88%,
--- ---
substantially all of our mortgage debt bears interest at fixed rates, and
--- ---
in 2026, 2027 and 2028, 5.5%, 9.3% and 7.6%, respectively, of our total scheduled principal mortgage payments (i.e., amortization and balances due at maturity) is due.
--- ---

We monitor the risk of tenant non-payments through a variety of approaches tailored to the applicable situation. Generally, based on our assessment of the credit risk posed by our tenants, we monitor a tenant’s financial condition through one or more of the following actions: reviewing tenant financial statements or other financial information, obtaining other tenant related information, reviewing changes in tenant payment patterns, regular contact with tenant’s representatives, tenant credit checks and regular management reviews of our tenants. We may sell a property if the tenant’s financial condition is unsatisfactory.

We monitor, on an ongoing basis, our expiring leases and generally approach tenants with expiring leases (including those subject to renewal options) at least a year prior to lease expiration to determine their interest in renewing their leases. During the three years ending December 31, 2028, 70 leases for 64 tenants at 47 properties representing $30.9 million, or 37.4%, of 2026 base rent expire.

In acquiring properties, we balance an evaluation of the terms of the leases and the credit of the existing tenants with a fundamental analysis of the real estate to be acquired, which analysis takes into account, among 27

Table of Contents other things, the estimated value of the property, local demographics and the ability to re-rent or dispose of the property on favorable terms upon lease expiration or early termination.

2025 Activities

In 2025, we:

acquired 13 industrial properties for an aggregate purchase price of $188.8 million, including $112.3 million in mortgage debt. These properties account for $12.5 million, or 15.1%, of our 2026 base rent and we anticipate that in 2026, these properties will generate $13.3 million of rental income (excluding tenant reimbursements), $8.4 million of depreciation and amortization expense and $6.5 million of interest expense.
sold ten properties (i.e., seven retail, a restaurant, a veterinary hospital and a property ground leased to a multi-unit apartment complex owner/operator) for an aggregate net sales proceeds of $58.9 million and an aggregate net gain on sale of real estate of $18.7 million. The properties sold accounted for $2.4 million, or 2.4%, and $4.5 million, or 5.0%, of 2025 and 2024 rental income, net, respectively.
--- ---
sold two joint venture properties - our 50% share of the (i) net sales proceeds was $2.4 million and (ii) gain on sales was $991,000.
--- ---

Recent Developments

We purchased, on January 29, 2026, a 637,633 square foot portfolio comprised of ten industrial properties (the “Portfolio Acquisition”) located in seven markets (i.e., Greensboro, North Carolina, Columbia, South Carolina, Birmingham, Alabama, Omaha, Nebraska, Oklahoma City, Oklahoma, Salt Lake City, Utah and Jackson, Mississippi) and leased to six tenants (i.e., Mondelez Global, Husqvarna U.S. Holdings, L&W Supply Corporation, Owens & Minor Distribution, Bimbo Bakeries USA, and HABE USA), for $56.7 million, including new mortgage debt on six of the properties of $17.0 million bearing an interest rate of 5.53% and maturing in 2033. We also borrowed $30.0 million from our credit facility (which bears a fluctuating interest rate of 5.45% at January 29, 2026) in connection with this purchase. We anticipate paying down our credit facility debt from the net proceeds of property sales and mortgage financing on two of the unencumbered properties included in the Portfolio Acquisition. As of January 29, 2026, the base rent in 2026 for these properties is approximately $2.8 million, and we estimate that after giving effect to anticipated lease renewals (as to which no assurance can be provided), the 2026 base rent for these properties will be approximately $3.6 million. We also estimate that in 2026, these properties will generate $2.6 million of interest expense (including $1.7 million of such expense from the credit facility assuming an interest rate of 5.45% and that $30.0 million remains outstanding thereon).

As of February 27, 2026, $30.0 million is outstanding under our credit facility bearing a floating rate of interest of 5.42% per year.

Pending Transactions

We entered into a contract in:

October 2025, to sell a vacant retail property located in Cary, North Carolina for $6.0 million. It is anticipated the (i) property will be sold in March 2026 and (ii) sale will result in a gain of approximately $2.5 million, which will be recognized as Gain on sale of real estate, net, in the consolidated statement of income for the quarter ending March 31, 2026. This property accounted for $192,000 and $460,000 of rental income, net, $93,000 and $93,000 of depreciation and amortization expense, and $45,000 and $110,000 of mortgage interest expense for 2025 and 2024, respectively.
January 2026, to sell a retail property located in Newport News, Virginia for $4.2 million. It is anticipated the (i) property will be sold in April 2026 and (ii) sale will result in a gain of approximately $1.3 million, which will be recognized as Gain on sale of real estate, net, in the consolidated statements of income for the three and six months ending June 30, 2026. This property accounted for $360,000 and $340,000 of rental income, net, and $115,000 and $113,000 of depreciation and amortization expense for 2025 and 2024, respectively.
--- ---

Changes at same store properties

The increase in same store rental income is due to increases of:

- $1.5 million of rental income from various lease amendments and extensions at several properties,

- $1.2 million of rental income due to new and/or replacement tenants at several properties, and

- $422,000 in tenant reimbursements, of which $361,000 relates to insurance and common area maintenance expenses generally incurred in the same year.

The increase was offset by decreases in rental income of $2.0 million from leases that expired in 2024 and 2025 at several properties.

Lease Termination Fees

In 2024, a consolidated joint venture in Lakewood, Colorado, in which we held a 90% interest, received a lease termination fee of $250,000 from a tenant due to the early termination of its lease in connection with the sale of the related restaurant parcel. We anticipate recognizing, during the quarter ending March 31, 2026, aggregate lease termination fees of approximately $1.3 million, and that in the aggregate, we will replace such tenancies on economic terms more favorable to us than those of the terminating tenancies. 29

Table of Contents Operating Expenses

The following table compares operating expenses for the periods indicated:

Year Ended December 31, Increase
(Dollars in thousands) ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ (Decrease) ​ ​ ​ % Change
Operating expenses:
Depreciation and amortization $ 27,196 $ 24,291 $ 2,905 12.0
Real estate expenses 19,878 17,904 1,974 11.0
General and administrative 16,267 15,388 879 5.7

State tax expense 73 1 72 7,200.0
Total operating expenses $ 68,007 $ 58,670 $ 9,337 15.9

Depreciation and amortization. The increase is due primarily to:

- $4.7 million of such expense from the properties acquired in 2025 and 2024 (including $970,000 from the three properties acquired in 2024), and

- $415,000 of depreciation from improvements at several same store properties.

The increase was offset by:

- the inclusion, in 2024, of $1.3 million of such expense from the properties sold since January 1, 2024, and

- a decrease, in 2025, of $959,000 related to tenant origination costs at several same store properties that prior to December 31, 2025 were fully amortized.

Real estate expenses.

The increase is primarily due to:

- $2.0 million from properties acquired in 2025 and 2024 (including $529,000 from the properties acquired in 2024), and

- aggregate increases of $1.0 million of real estate expenses (i.e., real estate taxes, insurance and common area maintenance expenses) for several same store properties, none of which was individually significant.

The increase was offset primarily by a $1.1 million decrease related to properties sold in 2024 and 2025.

A substantial portion of real estate expenses (i.e., $16.6 million and $14.8 million in 2025 and 2024, respectively) are rebilled to tenants and are included in Rental income, net, on the consolidated statements of income.

General and administrative. The increase in 2025 is due primarily to increases of (i) non-cash expense of $371,000 from the re-assessment of the achievability of performance metrics related to the RSUs and (ii) $208,000 due to higher levels of compensation and compensation-related expense. The balance of the increase is due to various factors, none of which was individually significant.

Impairment losses. During 2025, we recorded an aggregate impairment loss of $4.6 million at our St. Louis Park, Minnesota and Beachwood, Ohio properties. During 2024, we recorded a $1.1 million impairment loss at our former Hamilton, Ohio property. (See Note 5 to our consolidated financial statements).

Equity in earnings from sale of unconsolidated joint venture properties. The 2025 results reflect our 50% share of the gain on the sales of our two Savannah, Georgia joint venture properties which were sold in August 2025. (See Note 7 to our consolidated financial statements).

Income on settlement of litigation. During the quarter ended December 31, 2025, we received $1.3 million in connection with the settlement of a lawsuit at our former Beachwood, Ohio property. (See Note 13 to our consolidated financial statements).

Other income. The change in 2025 is due to a decrease of $478,000 in interest income primarily from the decrease in amounts available for investment in short-term U.S. treasury bills.

Interest expense. The following table compares interest expense for the periods indicated:

Mortgage interest

The following table reflects the weighted average interest rate on the weighted average principal amount of outstanding mortgage debt during the applicable year:

Year Ended December 31, Increase

Weighted average principal amount $ 466,825 $ 426,916 $ 39,909 9.3
Weighted average interest rate 4.75 % 4.47 % 0.28 % 6.3

The increase in 2025 is due primarily to the increases in the weighted average principal amount of mortgage debt outstanding and weighted average interest rate. Among other things, the mortgages (i) that we refinanced generally bore a higher interest rate than the mortgages we paid off and (ii) obtained in connection with acquisitions generally bore a higher rate of interest than the mortgages on properties we sold.

We estimate that after giving effect to the Portfolio Acquisition, that mortgage interest expense in 2026 will be approximately $25.9 million.

​ 32

Table of Contents Credit facility interest

During 2025, the weighted average interest rate was 6.07% and the weighted average principal amount outstanding was $3.4 million.

We estimate that after giving effects to the Portfolio Acquisition, that in 2026, interest expense on our credit facility will be approximately $1.7 million (assuming an interest rate of 5.45% as of January 29, 2026 and that there are no paydowns or drawdowns on the facility).

During 2024, there was no balance outstanding and the interest expense of $254,000 constitutes the unused facility fee.

Funds from Operations and Adjusted Funds from Operations

We compute funds from operations, or FFO, in accordance with the “White Paper on Funds From Operations” issued by the National Association of Real Estate Investment Trusts (“NAREIT”) and NAREIT’s related guidance. FFO is defined in the White Paper as net income (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, impairment write-downs of certain real estate assets and investments in entities where the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. In computing FFO, we do not add back to net income the amortization of costs in connection with our financing activities or depreciation of non-real estate assets.

We compute adjusted funds from operations, or AFFO, by adjusting FFO for straight-line rent accruals and amortization of lease intangibles, deducting from income (i) additional rent from a ground lease tenant, (ii) income on settlement of litigation, (iii) income on insurance recoveries from casualties, (iv) lease termination and assignment fees, and adding back to income (i) amortization of restricted stock and restricted stock unit compensation expense, (ii) amortization of costs in connection with its financing activities (including its share of its unconsolidated joint ventures), (iii) debt prepayment costs, (iv) amortization of lease incentives and (v) mortgage intangible assets. Since the NAREIT White Paper does not provide guidelines for computing AFFO, the computation of AFFO varies from one REIT to another.

We believe that FFO and AFFO are useful and standard supplemental measures of the operating performance for equity REITs and are used frequently by securities analysts, investors and other interested parties in evaluating equity REITs, many of which present FFO and AFFO when reporting their operating results. FFO and AFFO are intended to exclude GAAP historical cost depreciation and amortization of real estate assets, which assumes that the value of real estate assets diminish predictably over time. In fact, real estate values have historically risen and fallen with market conditions. As a result, we believe that FFO and AFFO provide a performance measure that when compared year over year, should reflect the impact to operations from trends in occupancy rates, rental rates, operating costs, interest costs and other matters without the inclusion of depreciation and amortization, providing a perspective that may not be necessarily apparent from net income. We also consider FFO and AFFO to be useful in evaluating potential property acquisitions.

FFO and AFFO do not represent net income or cash flows from operating, investing or financing activities as defined by GAAP. FFO and AFFO should not be considered to be an alternative to net income as a reliable measure of our operating performance; nor an alternative to cash flows from operating, investing or financing activities (as defined by GAAP) as measures of liquidity. FFO and AFFO do not measure whether cash flow is sufficient to fund all of our cash needs, including principal amortization, capital improvements and distributions to stockholders.

Management recognizes that there are limitations in the use of FFO and AFFO. In evaluating our performance, management is careful to examine GAAP measures such as net income and cash flows from operating, investing and financing activities. 33

Table of Contents Liquidity and Capital Resources

Our sources of liquidity and capital include cash flow from operations, cash and cash equivalents, borrowings under our credit facility, refinancing existing mortgage loans, obtaining mortgage loans secured by our unencumbered properties, issuance of our equity securities and property sales. In 2025, we obtained approximately (i) $61.3 million of net proceeds from property sales (after giving effect to $7.5 million of mortgage debt repayments) and (ii) $129.0 million of proceeds from mortgage financings (after giving effect to $3.8 million of refinanced amounts). Our available liquidity at February 27, 2026 was approximately $78.5 million, including approximately $8.5 million of cash and cash equivalents (including the credit facility’s required $3.0 million average deposit maintenance balance) and, subject to borrowing base requirements, up to $70.0 million available under our credit facility.

Liquidity and Financing

We expect to meet our short-term (i.e., one year or less) and long-term (i) operating cash requirements (including debt service and anticipated dividend payments) principally from cash flow from operations, our available cash and cash equivalents, proceeds from and, to the extent permitted and needed, our credit facility and (ii) investing and financing cash requirements (including an estimated aggregate of $2.7 million of capital expenditures) from the foregoing, as well as property financings, property sales and sales of our common stock.

The following table sets forth, as of December 31, 2025, information with respect to our mortgage debt that is payable from January 2026 through December 31, 2028:

(Dollars in thousands) ​ ​ ​ 2026 ​ ​ ​ 2027 ​ ​ ​ 2028 ​ ​ ​ Total
Amortization payments $ 11,108 $ 10,151 $ 9,516 $ 30,775
Principal due at maturity 17,767 38,525 30,155 86,447
Total $ 28,875 $ 48,676 $ 39,671 $ 117,222

We intend to make debt amortization payments from operating cash flow and, though no assurance can be given that we will be successful in this regard, generally intend to refinance, extend or payoff the mortgage loans which mature in 2026 through 2028. We intend to repay the amounts not refinanced or extended from our existing funds and sources of funds, including our available cash, proceeds from one or more property sales, the sale of our common stock and our credit facility (to the extent available).

We continually seek to refinance existing mortgage loans on terms we deem acceptable to generate additional liquidity. Additionally, in the normal course of our business, we sell properties when we determine that it is in our best interests, which also generates additional liquidity. Further, although we have done so infrequently and primarily in the context of a tenant default at a property for which we have not found a replacement tenant, if we believe we have negative equity in a property subject to a non-recourse mortgage loan, we may convey such property to the mortgagee to terminate our mortgage obligations, including payment of interest, principal and real estate taxes, with respect to such property.

Typically, we utilize funds from our credit facility to acquire a property and, thereafter secure long-term, fixed rate mortgage debt on such property. We apply the proceeds from the mortgage loan to repay borrowings under the credit facility, thus providing us with the ability to re-borrow under the credit facility for the acquisition of additional properties. 36

(a) At December 31, 2025, there was no balance outstanding on the credit facility and at February 27, 2026, $30,000 was outstanding on the credit facility. We anticipate paying down the facility in the next twelve months from the net proceeds of property sales and mortgage financings on two properties acquired in the Portfolio Acquisition. At December 31, 2025 and February 27, 2026, after giving effect to the facility’s borrowing base requirements, $100,000 and $70,000, respectively, was available to be borrowed. See “—Credit Facility”.
--- ---
(b) Assumes that approximately $4,170 will be payable annually during the next five years pursuant to the compensation and services agreement. Excludes (i) approximately $2,700 of capital expenditures to be incurred in the ordinary course of business in connection with tenant improvements, (ii) amounts required to acquire properties, (iii) subject to Board approval, $195,000 of dividend payments anticipated to be paid through December 31, 2030 (assuming no changes in the number of shares of common stock outstanding and the dividend rate from December 31, 2025).
--- ---

As of December 31, 2025, we had $522.5 million of mortgage debt outstanding, all of which is non-recourse (subject to standard carve-outs). We expect that mortgage interest and amortization payments (excluding repayments of principal at maturity) of approximately $100.6 million due through 2028 will be paid primarily from cash generated from our operations. We anticipate that principal balances due at maturity through 2028 of $86.4 million will be paid primarily from cash and cash equivalents and mortgage financings and refinancings. If we are unsuccessful in refinancing our existing indebtedness or financing our unencumbered properties, our cash flow, funds available under our credit facility and available cash, if any, may not be sufficient to repay all debt obligations when payments become due, and we may need to issue additional equity, obtain long or short-term debt, or dispose of properties on unfavorable terms.

Credit Facility

Our credit facility provides that subject to borrowing base requirements, we can borrow up to $100.0 million for the acquisition of commercial real estate, repayment of mortgage debt, and renovation and operating expense purposes; provided, that if used for renovation and operating expense purposes, the amount outstanding for such purposes will not exceed the lesser of $40.0 million and 40% of the borrowing base. See “ Liquidity and Capital Resources”. The facility matures December 31, 2026 and we anticipate that it will be renewed prior thereto. The facility bears interest equal to 30-day SOFR plus the applicable margin. The applicable margin ranges from 175 basis points if our ratio of total debt to total value (as calculated pursuant to the facility) is equal to or less than 50%, increasing to a maximum of 275 basis points if such ratio is greater than 60%. The applicable margin was 175 basis points for each of 2025 and 2024. There is an unused facility fee of 0.25% per annum on the difference between the outstanding loan balance and $100.0 million. The credit facility requires the maintenance of $3.0 million in average deposit balances. For 2025, the weighted average interest rate on the facility was approximately 6.07% and as of February 27, 2026, the rate on the facility was 5.42%.

The terms of our credit facility include certain restrictions and covenants which may limit, among other things, the incurrence of liens, and which require compliance with financial ratios relating to, among other things, the minimum amount of tangible net worth, the minimum amount of debt service coverage, the minimum amount of fixed charge coverage, the maximum amount of debt to value, the minimum level of net income, certain investment limitations and the minimum value of unencumbered properties and the number of such properties. Net proceeds received from the sale, financing or refinancing of properties are generally required to be used to repay amounts outstanding under our credit facility. 37

Table of Contents Inflation

We are exposed to inflation risk as income from long-term leases is the primary source of our cash flows from operations. Many of our leases contain provisions, including provisions providing for periodic fixed rate rent increases), intended to mitigate the impact of inflation. In addition, many of our leases require the tenant to pay, or reimburse us for our payment of, all or a majority of the property’s operating expenses, including real estate taxes, utilities, insurance and building repairs, which may also mitigate our risks associated with rising costs. However, these rent escalation or reimbursement provisions may not adequately offset the effects of inflation.

Inflation will also affect the overall cost of our floating rate debt (i.e., primarily debt incurred pursuant to our credit facility) and affects the mortgage debt we may incur in the future. (The interest rate risk associated with substantially all of our current mortgage debt is generally mitigated through long-term fixed interest rate loans). Increasing interest rates on acquisition mortgage debt limits the acquisition opportunities we can pursue and reduces the prices at which we sell our properties.

Distribution Policy

We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. Accordingly, to qualify as a REIT, we must, among other things, meet a number of organizational and operational requirements, including a requirement that we distribute currently at least 90% of our ordinary taxable income to our stockholders. It is our current intention to comply with these requirements and maintain our REIT status. As a REIT, we generally will not be subject to corporate federal, state or local income taxes on taxable income we distribute currently (in accordance with the Internal Revenue Code and applicable regulations) to our stockholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal, state and local income taxes at regular corporate rates and may not be able to qualify as a REIT for four subsequent tax years. Although we qualify for federal taxation as a REIT, we are subject to certain state and local taxes on our income and to federal income taxes on our undistributed taxable income (i.e., taxable income not distributed in the amounts and in the time frames prescribed by the Internal Revenue Code and applicable regulations thereunder) and are subject to Federal excise taxes on our undistributed taxable income.

It is our current intention to pay to our stockholders within the time periods prescribed by the Internal Revenue Code no less than 90%, and, if possible, 100% of our annual taxable income, including taxable gains from the sale of real estate. It will continue to be our policy to make sufficient distributions to stockholders in order for us to maintain our REIT status under the Internal Revenue Code.

Our board of directors will continue to evaluate, on a quarterly basis, the amount and nature (i.e., cash, stock or a combination of the foregoing) of dividend payments based on its assessment of, among other things, our short and long-term cash and liquidity requirements, prospects, debt maturities, maintenance of our REIT status, projections of our REIT taxable income, net income, funds from operations and adjusted funds from operations. 38

Table of Contents Critical Accounting Estimates

Our discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. On an ongoing basis, we reconsider and evaluate our estimates and assumptions.

We base our estimates on historical experience, current trends and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could materially differ from any of our estimates under different assumptions or conditions. Our significant accounting policies are discussed in Note 2 of our consolidated financial statements in this report. We believe the accounting estimates listed below are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain.

Revenue Recognition

Our main source of revenue is rental income from our tenants. Rental income primarily includes: (i) base rents that our tenants pay in accordance with the terms of their respective leases reported on a straight-line basis over the non-cancellable term of each lease and (ii) reimbursements by tenants of certain real estate operating expenses. Since many of our leases provide for rental increases at specified intervals, straight-line basis accounting requires us to record as an asset and include in revenues, unbilled rent receivables which we will only receive if the tenant makes all rent payments required through the expiration of the term of the lease. Accordingly, our management must determine, in its judgment, that the unbilled rent receivable applicable to each specific tenant is collectable. We review unbilled rent receivables on a quarterly basis and take into consideration, among other things, the tenant’s payment history and the financial condition of the tenant. In the event that the collectability of an unbilled rent receivable is unlikely, we are required to write-off the receivable, which has an adverse effect on net income for the year in which the direct write-off is taken, and will decrease total assets and stockholders’ equity.

Purchase Accounting for Acquisition of Real Estate

The fair value of real estate acquired is allocated to acquired tangible assets (which includes land, building and building improvements) and identified intangible assets and liabilities (which include the value of above, below and at-market leases, origination costs associated with in-place leases and above and below-market mortgages assumed) based in each case on their relative fair values. 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 building improvements based on our determination of the relative fair values of these assets. We assess the fair value of the lease intangibles and assumed mortgages based on estimated cash flow projections that utilize appropriate discount rates and available market information. The fair values associated with below-market rental renewal options are determined based on our experience and the relevant facts and circumstances that existed at the time of the acquisitions. The portion of the values of the leases associated with below-market renewal options that we deem reasonably certain to be exercised by the tenant are amortized to rental income over the respective renewal periods. The allocation made by us may have a positive or negative effect on net income and may have an effect on the assets and liabilities on the balance sheet.

​ 39

Table of Contents Carrying Value of Real Estate Portfolio

We review our real estate portfolio on a quarterly basis to ascertain if there are any indicators of impairment to the value of any of our real estate assets, including deferred costs and intangibles, to determine if there is any need for an impairment charge. In reviewing the portfolio, we examine, among other things, the type of asset, the current financial statements or other available financial information of the tenant, the economic situation in the area in which the asset is located, the economic situation in the industry in which the tenant is involved and the timeliness of the payments made by the tenant under its lease, as well as any current correspondence that may have been had with the tenant, including property inspection reports. For each real estate asset owned for which indicators of impairment exist, we perform a recoverability test by comparing the sum of the estimated undiscounted future cash flows attributable to the asset to its carrying amount. Management’s assumptions and estimates include projected rental rates during the holding period and property capitalization rates in order to estimate undiscounted future cash flows. If the undiscounted cash flows are less than the asset’s carrying amount, an impairment loss is recorded to the extent that the estimated fair value is less than the asset’s carrying amount. The estimated fair value is determined using a discounted cash flow model of the expected future cash flows through the useful life of the property. Real estate assets that are expected to be disposed of are valued at the lower of carrying amount or fair value less costs to sell on an individual asset basis. We generally do not obtain any independent appraisals in determining value but rely on our own analysis and valuations. Any impairment charge taken with respect to any part of our real estate portfolio will reduce our net income and reduce assets and stockholders’ equity to the extent of the amount of any impairment charge, but it will not affect our cash flow or our distributions until such time as we dispose of the property.

Equity-Based Compensation

We grant shares of restricted stock and restricted stock units (“RSUs”) to eligible plan participants, subject to the recipient’s continued service over a specified period and, with respect to the RSUs, the satisfaction of specified conditions over a specified period. The RSUs vest based upon satisfaction of specified metrics with respect to the (i) average of our annual total stockholder return (“TSR Awards”) and/or (ii) average annual return of capital (“ROC Awards”), in each case as calculated pursuant to the applicable award agreement. We account for the restricted stock awards and RSUs in accordance with ASC 718, Compensation - Stock Compensation, which requires that such compensation be recognized in the financial statements based on its estimated grant date fair value. The value of such awards is recognized as compensation expense in general and administrative expenses in the accompanying consolidated statements of operations over the applicable service periods. Grant date fair value is determined with respect to the (i) restricted stock awards, by the closing stock price on the date of grant, (ii) TSR Awards, by using a Monte Carlo simulation relying upon various assumptions and (iii) ROC Awards, by the closing stock price on the date of grant, subject to quarterly adjustment based upon management’s projections as to the achievability of the specified metrics related to the ROC Awards (the “ROC Metrics”). There is substantial subjectivity in (i) the inputs selected for the Monte Carlo simulation used in determining the grant date fair value of the TSR Awards and the use of different inputs would change the expense we recognize with respect to such awards and (ii) management’s projections as to the achievability of the ROC Metrics and changes in such projections will cause fluctuations in our results of operations. See Note 10 to our consolidated financial statements.

Table of Contents Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Our primary market risk exposure is the effect of changes in interest rates on the interest cost of draws on our revolving variable rate credit facility and the effect of changes in the fair value of our interest rate swap agreements. Interest rates are highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control.

We use interest rate swaps to limit interest rate risk on substantially all variable rate mortgages. These swaps are used for hedging purposes-not for speculation. We do not enter into interest rate swaps for trading purposes. At December 31, 2025, we had no liability in the event of the early termination of our swaps.

At December 31, 2025, we had two interest rate swap agreements outstanding with an aggregate $1.6 million notional amount. The fair market value of the interest rate swaps is dependent upon existing market interest rates and swap spreads, which change over time. As of December 31, 2025, if there had been an increase of 100 basis points in forward interest rates, the fair market value of the interest rate swaps and the net unrealized gain on derivative instruments would have increased by $7,000. If there were a decrease of 100 basis points in forward interest rates, the fair market value of the interest rate swaps and the net unrealized gain on derivative instruments would have decreased by $7,000. These changes would not have any impact on our net income or cash.

The fair market value of our long-term debt is estimated based on discounting future cash flows at interest rates that our management believes reflect the risks associated with long-term debt of similar risk and duration.

The following table sets forth our debt obligations by scheduled principal cash flow payments and maturity date, weighted average interest rates and estimated fair market value at December 31, 2025:

Evaluation of Disclosure Controls and Procedures

A review and evaluation was performed by our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this Annual Report on Form 10-K. Based on that review and evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures, as designed and implemented as of December 31, 2025, were effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, a company’s principal executive and principal financial officers and effected by a company’s board, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that:

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of a company;
provide reasonable assurance that transactions are recorded as necessary to permit the preparation of financial statements in accordance with GAAP, and that receipts and expenditures of a company are being made only in accordance with authorizations of management and the board of directors of a company; and
--- ---
provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use or disposition of a company’s assets that could have a material effect on the financial transactions.
--- ---

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, our management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013).

Based on its assessment, our management concluded that, as of December 31, 2025, our internal control over financial reporting was effective based on those criteria.

Changes in Internal Controls over Financial Reporting

There have been no changes in our internal controls over financial reporting, as defined in in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act, that occurred during the three months ended December 31, 2025 that materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

None of our officers or directors had any contract, instruction, or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement” in effect at any time during the three months ended December 31, 2025.

Impact of the One Big Beautiful Bill Act on the Company and its Stockholders

The discussion under “Federal Income Tax Considerations” in our prospectus dated September 1, 2023, as the same may have been amended or supplemented from time-to-time (the “Prospectus”), is hereby modified to reflect legislation commonly referred to as the One Big Beautiful Bill Act. Capitalized terms used in this section without being defined herein shall have the meanings ascribed to them by the Prospectus.

Enactment of the One Big Beautiful Bill Act: On July 4, 2025, legislation commonly referred to as the One Big Beautiful Bill Act (the “OBBBA”) was enacted into law. Among other changes, the OBBBA included a number of changes to the Code that affect the U.S. federal income tax laws applicable to REITs and their security holders. The most significant of those changes are described below. Prospective investors should consult their tax advisors regarding the effects of the OBBBA on their investment.

REIT Asset Tests: The OBBBA increases the ownership limit applicable to TRSs for taxable years ending after December 31, 2025. For taxable years ending after December 31, 2017 through December 31, 2025, not more than 20% of the value of our total assets may be represented by securities of one or more TRSs. For taxable years ending after December 31, 2025, not more than 25% of the value of our total assets may be represented by securities of one or more TRSs.

Pass-Through Business Income Tax Rate Lowered through Deduction: The OBBBA permanently extends the provisions allowing individuals and some trusts and estates to deduct up to 20% of “qualified REIT dividends,” which are REIT dividends other than capital gain dividends, dividends designated as eligible for capital gain tax rates and certain other income items discussed under “Impact of the Tax Cuts and Jobs Act on the Company and its Stockholders-Pass-Through Business Income Tax Rate Lowered through Deduction.”

Limitations on Interest Deductibility: The OBBBA eases the limitation on the deduction for net interest expense discussed under “Impact of the Tax Cuts and Jobs Act on the Company and its Stockholders-Limitations on Interest Deductibility,” by modifying the definition of “adjusted taxable income” which is one of the limitations on the deduction. For taxable years beginning after December 21, 2025, adjusted taxable income will again be calculated before any deductions for depreciation, amortization, and depletion.

Revised Individual Tax Rates and Deductions: The OBBBA permanently extends the individual income tax changes discussed under “Impact of the Tax Cuts and Jobs Act on the Company and its Stockholders-Revised Individual Tax rates and Deduction.”

The changes made by the OBBBA are complex and we cannot predict the long-term impact of the OBBBA, other new U.S. federal tax laws, and whether, when and how the OBBBA and other new U.S. federal tax laws will be affected by any administrative and judicial interpretations. Stockholders and prospective investors should consult their tax advisors regarding the effects of the OBBBA on their investment.

Table of Contents Report of Independent Registered Public Accounting Firm ****

To the Stockholders and the Board of Directors of One Liberty Properties, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of One Liberty Properties, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosures to which it relates.

Impairment of Real Estate Investments
Description of the Matter At December 31, 2025, the Company’s real estate investments totaled approximately $778 million. As described in Note 2 to the consolidated financial statements, investments in real estate are reviewed for impairment when circumstances indicate that the carrying value of a property may not be recoverable.<br><br>​<br><br>Auditing the Company’s impairment assessment for real estate investments was especially challenging and involved a high degree of subjectivity as a result of the assumptions and estimates inherent in the determination of estimated future cash flows expected to result from

F-1

Table of Contents

the property’s use and eventual disposition.  In particular, management’s assumptions and estimates included projected rental rates and property capitalization rates, which were sensitive to expectations about future operating income, trends and prospects, leasing demand and competition.<br><br>​
How We Addressed the Matter in Our Audit To test the Company's impairment assessment for real estate investments, we performed audit procedures that included, among others, evaluating the methodologies applied and testing the significant assumptions discussed above and the underlying data used by the Company in its impairment analyses. In certain cases, we involved our valuation specialists to assist in performing these procedures.  We compared the significant assumptions used by management to historical data and observable market-specific data.  We also performed sensitivity analyses of significant assumptions to evaluate the changes in estimated future cash flows that would result from changes in the assumptions.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 1989.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2025

NOTE 1 — ORGANIZATION AND BACKGROUND

One Liberty Properties, Inc. (“OLP”) was incorporated in 1982 in Maryland. OLP is a self-administered and self-managed real estate investment trust (“REIT”). OLP acquires, owns and manages a geographically diversified portfolio consisting primarily of industrial properties. As of December 31, 2025, OLP owns 103 properties, including a property owned by a consolidated joint venture. The 103 properties are located in 30 states.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts and operations of OLP, its wholly owned subsidiaries, its joint ventures in which the Company, as defined, has a controlling interest, and variable interest entities (“VIEs”) of which the Company is the primary beneficiary. OLP and its consolidated subsidiaries are referred to herein as the “Company”. Material intercompany items and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Management believes that the estimates and assumptions that are most important to the portrayal of the Company’s consolidated financial condition and results of operations, in that they require management’s most difficult, subjective or complex judgments, form the basis of the accounting policies deemed to be most significant to the Company. These significant accounting policies relate to revenues and the value of the Company’s real estate portfolio, including investments in unconsolidated joint ventures. Management believes its estimates and assumptions related to these significant accounting policies are appropriate under the circumstances; however, should future events or occurrences result in unanticipated consequences, there could be a material impact on the Company’s future consolidated financial condition or results of operations.

Revenue Recognition

Rental income includes the base rent that each tenant is required to pay in accordance with the terms of its lease reported over the non-cancelable term of the lease on a straight-line basis, if collectability is probable. On a quarterly basis, management reviews the tenant’s payment history and financial condition in determining, in its judgment, whether any accrued rental income and unbilled rent receivable balances applicable to a specific tenant is collectable. Any change to the collectability of lease payments or unbilled rent receivables is recognized as a current period adjustment to rental revenue (see Note 3).

Some leases provide for increases based on the Consumer Price Index or for additional contingent rental revenue in the form of percentage rents. The percentage rents are based upon the level of sales achieved by the lessee and are recognized once the required sales levels are reached. Some leases provide for an incentive for the lessee to sign a lease, such as a leasehold improvement allowance in which the Company reimburses the tenant for the construction of lessee assets. Such lease incentives are capitalized at lease commencement and recognized on a straight-line basis over the lease term as a reduction to rental income. F-9

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Many of the Company’s properties are subject to long-term net leases under which the tenant is typically responsible to pay directly to the vendor the real estate taxes, insurance, utilities and ordinary maintenance and repairs related to the property, and the Company is not the primary obligor with respect to such items. As a result, the revenue and expenses relating to these properties are recorded on a net basis. For certain properties, in addition to contractual base rent, the tenants pay their contractual share of real estate taxes and operating expenses to the Company. The revenue and expenses associated with properties at which the Company is the primary obligor are generally recorded on a gross basis. During 2025, 2024 and 2023, the Company recorded reimbursements of expenses of $16,635,000, $14,793,000 and $13,636,000, respectively, which are included in Rental income, net, in the accompanying consolidated statements of income.

Gains and losses on the sale of real estate investments are recorded when the Company no longer holds a controlling financial interest in the entity which holds the real estate investment and the relevant revenue recognition criteria under GAAP have been met.

Purchase Accounting for the Acquisition of Real Estate

In acquiring real estate, the Company evaluates whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, and if that requirement is met, the asset group is accounted for as an asset acquisition and not a business combination. Transaction costs incurred with such asset acquisitions are capitalized to real estate assets and depreciated over the respectful useful lives.

The Company allocates the purchase price of real estate, including direct transaction costs applicable to an asset acquisition, among land, building, improvements and intangibles (e.g., the value of above, below and at-market leases, origination costs associated with in-place leases and above or below-market mortgages assumed at the acquisition date). The value, as determined, is allocated to the gross assets acquired based on management’s determination of the relative fair values of these assets and liabilities.

The Company assesses the fair value of the gross assets acquired based on available market information which utilize estimated cash flow projections; such inputs are categorized as Level 3 inputs in the fair value hierarchy. In determining fair value, factors considered by management include an evaluation of current market demand, market capitalization rates and discount rates, estimates of carrying costs (e.g., real estate taxes, insurance and other operating expenses), and lost rental revenue during the expected lease-up periods. Management also estimates costs to execute similar leases, including leasing commissions and tenant improvements.

The values of acquired above-market and below-market leases are recorded based on the present values (using discount rates which reflect the risks associated with the leases acquired) of the difference between the contractual amounts to be received and management’s estimate of market lease rates, measured over the terms of the respective leases that management deemed appropriate at the time of the acquisition. Such valuations include a consideration of the non-cancellable terms of the respective leases, as well as any applicable renewal period(s). The fair values associated with below-market rental renewal options are determined based on the Company’s experience and other relevant factors at the time of the acquisition. The values of above-market leases are amortized as a reduction to rental income over the terms of the respective non-cancellable lease periods. The values of below-market leases are amortized as an increase to rental income over the terms of the respective non-cancellable lease periods. The portion of the values of the leases associated with below-market renewal options that management deemed are reasonably certain to be exercised by the tenant are amortized to rental income over such renewal periods. The value of other intangible assets (i.e., origination costs) is recorded to amortization expense over the remaining term of the respective leases. If a lease is terminated prior to its contractual expiration date or not renewed, all unamortized amounts relating to that lease are recognized in operations at such time. The estimated remaining useful lives of intangibles assets or liabilities range from approximately less than one year to 21 years. F-10

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

The values of assumed mortgages are recorded based on the present values (using discount rates which reflect the risks associated with the mortgage assumed) of the difference between the contractual amounts to be paid at the stated interest rates and management’s estimate of market interest rates for similar debt, at the time of the acquisition, measured over the term of such debt. The values of above or below-market mortgages are amortized as a decrease or increase, respectively, to interest expense over the term of the respective debt. The estimated remaining useful lives of intangible mortgage assets range from approximately three to four years.

Accounting for Long-Lived Assets and Impairment of Real Estate Owned

The Company reviews its real estate portfolio on a quarterly basis for indicators of impairment to the value of any of its real estate assets, including deferred costs and intangibles, to determine if there is any need for an impairment charge. In reviewing the portfolio, the Company examines one or more of the following: the type of asset, the current financial statements or other available financial information of the tenant, prolonged or significant vacancies, the economic environment of the area in which the asset is located and the industry in which the tenant is involved, the timeliness of the payments made by the tenant under its lease, property inspection reports and communication with, by, or relating to, the tenant. For each real estate asset owned for which indicators of impairment exist, management performs a recoverability test by comparing (i) the sum of the estimated undiscounted future cash flows attributable to the asset, which are determined using assumptions and estimates, including projected rental rates over an appropriate holding period and property capitalization rates, to (ii) the carrying amount of the asset. If the aggregate undiscounted cash flows are less than the asset’s carrying amount, an impairment is recorded to the extent that the estimated fair value is less than the asset’s carrying amount. The estimated fair value is determined using a discounted cash flow model of the expected future cash flows through the useful life of the property. The analysis includes an estimate of the future cash flows that are expected to result from the real estate investment’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, the effects of leasing demand, competition and other factors. Real estate assets that are expected to be disposed of are valued at the lower of carrying amount or fair value less costs to sell on an individual asset basis.

Properties Held-for-Sale

Real estate investments are classified as properties held-for-sale when management determines that the investment meets the applicable criteria. Real estate assets that are classified as held-for-sale are: (i) valued at the lower of carrying amount or the estimated fair value less costs to sell on an individual asset basis; and (ii) not depreciated.

Investment in Joint Ventures and Variable Interest Entities

The Financial Accounting Standards Board, or FASB, provides guidance for determining whether an entity is a VIE. VIEs are defined as entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A VIE is required to be consolidated by its primary beneficiary, which is the party that (i) has the power to control the activities that most significantly impact the VIE’s economic performance and (ii) has the obligation to absorb losses, or the right to receive benefits, of the VIE that could potentially be significant to the VIE.

The Company assesses the accounting treatment for each of its investments, including a review of each venture or limited liability company or partnership agreement, to determine the rights of each party and whether F-11

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

those rights are protective or participating. The agreements typically contain certain protective rights, such as the requirement of partner approval to sell, finance or refinance the property and to pay capital expenditures and operating expenditures outside of the approved budget or operating plan. In situations where, among other things, the Company and its partners jointly (i) approve the annual budget, (ii) approve certain expenditures, (iii) prepare or review and approve the joint venture’s tax return before filing, or (iv) approve each lease at a property, the Company does not consolidate as the Company considers these to be substantive participation rights that result in shared, joint power over the activities that most significantly impact the performance of the joint venture or property. Additionally, the Company assesses the accounting treatment for any interest pursuant to which the Company may have a variable interest as a lessor. Leases may contain certain protective rights, such as the right of sale and the receipt of certain escrow deposits.

Distributions to each joint venture partner are determined pursuant to the applicable operating agreement and, in the event of a sale of, or refinancing of the mortgage encumbering the property owned by such venture, the distributions to the Company may be less than that implied by the Company’s equity ownership interest in the venture.

As of December 31, 2025, the Company has sold all the properties it held through unconsolidated joint ventures. The Company accounted for its investments in unconsolidated joint ventures under the equity method of accounting. The investments in unconsolidated joint ventures had sufficient equity at risk to permit the entity to finance its activities without additional subordinated financial support and, as a group, the holders of the equity at risk had power through voting rights to direct the activities of these ventures. As a result, none of these joint ventures were VIEs. In addition, the Company shared power with its co-managing members over these entities, and therefore the entities were not consolidated. These investments were recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for their share of equity in earnings, cash contributions and distributions. None of the joint venture debt was recourse to the Company, subject to standard carve-outs.

The Company has elected to follow the cumulative earnings approach when assessing, for the consolidated statement of cash flows, whether the distribution from the investee is a return of the investor’s investment as compared to a return on its investment. The source of the cash generated by the investee to fund the distribution is not a factor in the analysis (that is, it does not matter whether the cash was generated through investee refinancing, sale of assets or operating results). Consequently, the investor only considers the relationship

between the cash received from the investee to its equity in the undistributed earnings of the investee, on a cumulative basis, in assessing whether the distribution from the investee is a return on or a return of its investment. Cash received from the unconsolidated entity is presumed to be a return on the investment to the extent that, on a cumulative basis, distributions received by the investor are less than its share of the equity in the undistributed earnings of the entity.

Fair Value Measurements

The Company measures the fair value of financial instruments based on the assumptions that market participants would use in pricing the asset or liability. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). As a basis for considering market participant assumptions in fair value measurements, a fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. In accordance with the fair value hierarchy, Level 1 assets/liabilities are valued based on quoted prices for identical instruments in active markets, Level 2 assets/liabilities are valued based on quoted prices in active markets for similar instruments, on quoted prices in less active or inactive markets, or on other “observable” market inputs and Level 3 assets/liabilities are valued based on significant “unobservable” market inputs.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Derivatives and Hedging Activities

The Company uses interest rate swaps to add stability to interest expense; not for trading or speculative purposes.

The Company records all derivatives on the consolidated balance sheets at fair value using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of the derivatives. In addition, the Company incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. These counterparties are generally large financial institutions engaged in providing a variety of financial services. These institutions generally face similar risks regarding adverse changes in market and economic conditions including, but not limited to, fluctuations in interest rates, exchange rates, equity and commodity prices and credit spreads.

The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows are considered cash flow hedges. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in accumulated other comprehensive income (outside of earnings) and subsequently reclassified to earnings in the period in which the hedged transaction becomes ineffective. For derivatives not designated as cash flow hedges, changes in the fair value of the derivative are recognized directly in earnings in the period in which the change occurs; however, the Company’s policy is to not enter into such transactions.

Stock Based Compensation

The fair value of restricted stock grants and restricted stock units (“RSUs”), determined as of the date of grant, is amortized into general and administrative expense over the respective vesting period. The deferred compensation to be recognized as expense is net of forfeitures. The Company recognizes the effect of forfeitures when they occur and previously recognized compensation expense is reversed in the period the grant or unit is forfeited. For share-based awards with a performance or market measure, the Company recognizes compensation expense over the requisite service period and the performance assumptions are re-evaluated quarterly. The requisite service period begins on the date the Compensation Committee of the Company’s Board of Directors authorizes the award, adopts any relevant performance measures and communicates the award to the recipient.

Income Taxes

The Company is qualified as a REIT under the applicable provisions of the Internal Revenue Code. Under these provisions, the Company will not be subject to Federal, and generally, state and local income taxes, on amounts distributed to stockholders, provided it distributes at least 90% of its ordinary taxable income and meets certain other conditions.

The Company follows a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that more-likely-than-not will be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than- **** not threshold of being sustained. The use of a valuation allowance as a substitute for derecognition of tax positions is prohibited. The Company has not identified any uncertain tax positions requiring accrual. F-13

Cash and Cash Equivalents

All highly liquid investments with original maturities of three months or less when purchased are considered to be cash equivalents.

Concentration of Credit Risk

The Company maintains cash accounts at various financial institutions. While the Company attempts to limit any financial exposure, some of its deposit balances exceed federally insured limits. The Company has not experienced any losses on such accounts.

The Company’s properties are located in 30 states. South Carolina is the only state in which the Company’s properties contributed more than 10% to total revenues (i.e., 11.8% in 2025, 11.6% in 2024 and 10.3% in 2023).

No tenant contributed over 10% to the Company’s total revenues in any of the past three years.

Escrows

Real estate taxes and other escrows aggregating $650,000 and $3,166,000 at December 31, 2025 and 2024, respectively, are included in Escrow, deposits and other assets and receivables.

Segment Reporting

Substantially all of the Company’s real estate assets, at acquisition, are comprised of real estate owned that is leased to tenants on a long-term basis. Therefore, the Company aggregates real estate assets for reporting purposes and operates in one reportable segment.

The Company’s Chief Operating Decision Makers (“CODMs”) are its Chief Executive Officer and Chief Operating Officer. As the Company operates in one reportable segment, the CODMs are provided the consolidated income statement (detailing total revenues, total operating expenses, operating income and net income). This financial report assists the CODMs in assessing the Company’s financial performance and in allocating resources appropriately.

New Accounting Pronouncement

In November 2024, the FASB issued ASU No. 2024*–03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220–40): Disaggregation of Income Statement Expenses, which requires disaggregated disclosure of income statement expenses into specified categories within the footnotes to the financial statements. ASU No. 2024–*03 is applicable for fiscal years beginning after December 15, 2026. The Company is in the process of evaluating the new guidance to determine the extent to which it will impact the Company’s consolidated financial statements. F-14

NOTE 3 — LEASES

Lessor Accounting

The Company owns rental properties which are leased to tenants under operating leases with current expirations ranging from 2026 to 2042, with options to extend or terminate the lease. Revenues from such leases are reported as Rental income, net, and are comprised of (i) lease components, which includes fixed and variable lease payments and (ii) non-lease components which includes reimbursements of property level operating expenses. The Company does not separate non-lease components from the related lease components, as the timing and pattern of transfer are the same, and account for the combined component in accordance with ASC 842.

Fixed lease revenues represent the base rent that each tenant is required to pay in accordance with the terms of its respective lease, and any lease incentives paid or payable to the lessee, reported on a straight-line basis over the non-cancelable term of the lease. Variable lease revenues typically include payments based on (i) tenant reimbursements, (ii) changes in the index or market-based indices after the inception of the lease and (iii) percentage rents. Variable lease revenues are not recognized until the specific events that trigger the variable payments have occurred.

The components of lease revenues are as follows (amounts in thousands):

Year Ended December 31,
​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023
Fixed lease revenues $ 79,391 $ 74,193 $ 75,935
Variable lease revenues 16,769 14,910 13,759
Lease revenues (a) $ 96,160 $ 89,103 $ 89,694
(a) Excludes $1,001, $1,210 and $952 of amortization related to lease intangible assets and liabilities for 2025, 2024 and 2023, respectively.
--- ---

In many of the Company’s leases, the tenant is obligated to pay the real estate taxes, insurance, and certain other expenses directly to the vendor. These obligations, which have been assumed by the tenants, are not reflected in the Company’s consolidated financial statements. To the extent any such tenant defaults on its lease or if it is deemed probable that the tenant will fail to pay for such obligations, a liability for such obligations would be recorded.

On a quarterly basis, the Company assesses the collectability of substantially all lease payments due by reviewing the tenant’s payment history or financial condition. Changes to collectability are recognized as a current period adjustment to rental revenue. As of December 31, 2025, the Company has assessed the collectability of all recorded lease revenues as probable. F-15

Straight-Line Rent

At December 31, 2025 and 2024, the Company’s unbilled rent receivables aggregating $17,269,000 and $16,988,000, respectively, represent rent reported on a straight-line basis in excess of rental payments required under the respective leases. The unbilled rent receivable is to be billed and received pursuant to the lease terms during the next 16 years.

During 2025, 2024 and 2023, the Company wrote-off $1,260,000, $1,045,000 and $1,048,000, respectively, of unbilled straight-line rent receivable related to the properties sold during such years, which reduced the gain on sale reported on the consolidated statements of income.

At December 31, 2025 and 2024, the Company’s unearned rental income aggregating $283,000 and $416,000, respectively, represent rent reported on a straight-line basis less than rental payments required under the respective leases. Such amounts are recorded in Accrued expenses and other liabilities on the consolidated balance sheets. The unearned rental income is to be recognized into revenue over the term of the lease during the next 16 years. During 2023, the Company wrote-off $43,000 of a tenant’s unearned rental income as the related property was sold during such year, which increased the gain on sale reported on the consolidated statement of income. No such amounts were written off during 2025 or 2024.

On a quarterly basis, the Company assesses the collectability of straight-line rent balances by reviewing the tenant’s payment history and financial condition. The Company has assessed the collectability of all straight-line rent balances as probable as of December 31, 2025. During 2024 and 2023, the Company wrote-off, as a reduction to rental income, net, $50,000 and $133,000, respectively, of unbilled rent receivables due from two tenants as they filed for Chapter 11 bankruptcy protection.

Lease Incentives

At December 31, 2025 and 2024, the Company’s unamortized lease incentives aggregating $708,000 and $975,000, respectively, are recorded in Escrow, deposits and other assets and receivables on the consolidated balance sheets. During 2025 and 2024, the Company amortized $107,000 and $119,000, respectively, of such incentives as a reduction to rental income. During 2025 and 2023, the Company wrote-off $160,000 and $84,000, respectively, related to two tenants’ unamortized lease incentive balances as the properties were sold, which reduced the gain on sale reported on the consolidated statements of income during such years. No such amounts were written off during 2024. The unamortized lease incentive balance will be amortized against rental income through 2033. F-16

Acquisitions subsequent to December 31, 2025

On January 29, 2026, the Company acquired a 637,633 square foot portfolio comprised of ten industrial properties for $56,700,000, including new mortgage debt of approximately $17,002,000 bearing an interest rate of 5.53% and maturing in 2033 and $30,000,000 borrowed on the Company’s credit facility. Simultaneously, the Company signed a contract to purchase from the same buyer an additional 14 acres of land for $800,000 adjacent to one of the properties in this portfolio.

Depreciation and Amortization

Depreciation of buildings is computed on the straight-line method over an estimated useful life of 40 years. Depreciation of building improvements is computed on the straight-line method over the estimated useful life of the improvements. If the Company determines it is the owner of tenant improvements, the amounts funded to construct the tenant improvements are treated as a capital asset and depreciated over the lesser of the remaining lease term or the estimated useful life of the improvements on the straight-line method. Leasehold interests and the related ground lease payments are amortized over the initial lease term of the leasehold position. During 2025, 2024 and 2023, the Company recorded depreciation expense (including amortization of a leasehold position, lease origination costs, and capitalized leasing commissions) of $27,196,000, $24,291,000 and $24,789,000, respectively.

NOTE 6 — VARIABLE INTEREST ENTITIES AND CONSOLIDATED JOINT VENTURES

As of December 31, 2025, the Company has one consolidated joint venture in which it holds a 95% interest.

Line of Credit

The Company’s credit facility with Manufacturers and Traders Trust Company and VNB New York, LLC, provides that it may borrow up to $100,000,000, subject to borrowing base requirements. The facility is available for the acquisition of commercial real estate, repayment of mortgage debt, and renovation and operating expense purposes; provided, that if used for renovation and operating expense purposes, the amount outstanding for such purposes will not exceed the lesser of $40,000,000 and 40% of the borrowing base. Net proceeds received from the sale, financing or refinancing of properties are generally required to be used to repay amounts outstanding under the credit facility. The facility is guaranteed by subsidiaries of the Company that own unencumbered properties and the Company is required to pledge to the lenders the equity interests in such subsidiaries.

The credit facility includes certain restrictions and covenants which may limit, among other things, the incurrence of liens, and which require compliance with financial ratios relating to, among other things, the minimum amount of tangible net worth, the minimum amount of debt service coverage, the minimum amount of fixed charge coverage, the maximum amount of debt to value, the minimum level of net income, certain investment limitations and the minimum value of unencumbered properties and the number of such properties.

At December 31, 2025 and 2024, the Company has no balance outstanding on the facility and was in compliance with all covenants.

The facility, which matures December 31, 2026, provides for an interest rate equal to 30-day SOFR plus an applicable margin ranging from 175 basis points to 275 basis points depending on the ratio of the Company’s total debt to total value, as determined pursuant to the facility. The applicable margin was 175 basis points at December 31, 2025 and 2024. An unused facility fee of .25% per annum applies to the facility. The weighted average interest rate on the facility was approximately 6.07% and 6.69% during 2025 and 2023. The Company had no balance outstanding on the facility during the year ended December 31, 2024.

As of December 31, 2025, the Company had in effect two interest rate derivatives, both of which were interest rate swaps, related to two outstanding mortgage loans with an aggregate $1,637,000 notional amount. These interest rate swaps, both of which (i) were designated as cash flow hedges, converting SOFR based variable rate mortgages to fixed annual rate mortgages, (ii) mature in July 2026 and (iii) have an interest rate of 3.24%.

Fair values are approximated using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivatives. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. Although the Company has determined the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the associated credit valuation adjustments use Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparty. As of December 31, 2025, the Company has assessed and determined the impact of the credit valuation adjustments on the overall valuation of its derivative positions is not significant. As a result, the Company determined its derivative valuation is classified in Level 2 of the fair value hierarchy. The Company does not currently own any financial instruments that are measured on a recurring basis and that are classified as Level 1 or 3.

At December 31, 2025 and 2024, the carrying and fair value of the Company’s derivative financial instruments was $16,000 and $208,000, respectively. The fair value of the Company’s derivatives is reflected in Escrow, deposits and other assets and receivables on the consolidated balance sheets. At December 31, 2025 and 2024, there were no derivatives in a liability position.

The following table presents the effect of the Company’s derivative financial instruments on the consolidated statements of income for the years presented (amounts in thousands):

Year Ended December 31,
2025 ​ ​ ​ 2024 ​ ​ ​ 2023
Amount of gain recognized on derivatives in other comprehensive income $ 12 $ 200 $ 328
Amount of reclassification from Accumulated other comprehensive income into Interest expense 204 836 1,295

During the twelve months ending December 31, 2025, the Company estimates an additional $16,000 will be reclassified from Accumulated other comprehensive income as a decrease to Interest expense.

The derivative agreements in effect at December 31, 2025 provide that if the wholly owned subsidiary of the Company which is a party to such agreement defaults or is capable of being declared in default on any of its indebtedness, then a default can be declared on such subsidiary’s derivative obligation. In addition, the Company is a party to the derivative agreements and if there is a default by the subsidiary on the loan subject to the derivative agreement to which the Company is a party and if there are swap breakage losses on account of the derivative being terminated early, the Company could be held liable for such swap breakage losses.

Fair Value on a Non-Recurring Basis

Non-financial assets measured at fair value on a non-recurring basis consist of three properties for which the Company recognized impairments on the consolidated statements of income of $4,593,000 and $1,086,000 for the years ended December 31, 2025 and 2024, respectively. The Company determined the estimated fair values of the assets using a market approach based on a non-binding letter of intent or executed contracts for sale which were determined to be Level 3 inputs in the fair value hierarchy (see Note 5).

Stock Based Compensation

The Company’s 2025, 2022 and 2019 Incentive Plans (collectively, the “Plans”), permit the Company to grant, among other things, stock options, restricted stock, RSUs, performance share awards and dividend equivalent rights and any one or more of the foregoing to its employees, officers, directors and consultants. A maximum of 750,000 shares of the Company’s common stock were authorized for issuance pursuant to each plan at such plan’s inception.

The following details the shares subject to awards that are outstanding under the Plans as of December 31, 2025:

Restricted Stock RSUs Totals

2019 Incentive Plan (b) 282,825 282,825
Totals 728,795 263,075 991,870
(a) On January 14, 2026, 161,285 restricted shares were issued pursuant to this plan with an aggregate grant date fair value of $3,414,000; of such awards, 6,830 shares are scheduled to vest in March 2026 and 154,455 shares are scheduled to vest in January 2031.
--- ---
(b) No additional awards may be granted under such plan.
--- ---

Restricted Stock

For accounting purposes, the restricted stock is not included in the shares shown as outstanding on the balance sheet until they vest; however, dividends are paid on the unvested shares. The restricted stock grants are charged to General and administrative expense over the respective vesting periods based on the market value of the common stock on the grant date. Generally, unless earlier forfeited because the participant’s relationship with the Company terminated, unvested restricted stock awards vest five years from the grant date, and under certain circumstances may vest earlier.

RSUs

The Metrics and other material terms and conditions of the RSUs are as follows:

Performance Criteria (a)
Year RSU Granted Metric Weight Minimum Maximum
2022 - 2025 (b)(c)(d) ROC Metric (e) 50% Average annual of at least 6.0% Average annual of at least 8.75%

(a) If the Metrics fall between the applicable minimum and maximum performance criteria, a pro-rata portion of such units (as calculated pursuant to the applicable award agreement), as applicable, vest.
--- ---
(b) The RSUs are not entitled to voting rights.
--- ---
(c) Upon vesting, the holders of such RSUs receive an amount equal to the dividends that would have been paid on the underlying shares had such shares been outstanding during the three-year performance cycle. As of December 31, 2025 and 2024, the Company accrued an aggregate of $474,000 and $408,000 of dividend equivalents, respectively, for the unvested RSUs based on the number of shares, underlying such RSUs, that would have been issued using performance and market assumptions determined at such dates.
--- ---
(d) In August 2025, the Company paid the holders of the 2022 RSU grant an aggregate of approximately $198,000 with respect to the dividend equivalent rights on the vested 36,704 shares.

--- ---
(e) The ROC Metrics meet the definition of a performance condition. Fair value is based on the market value on the date of grant. For ROC Awards, the Company does not recognize expense when performance conditions are not expected to be met; such performance assumptions are re-evaluated quarterly.
--- ---
(f) The TSR Metrics meet the definition of a market condition. A third-party appraiser prepares a Monte Carlo simulation pricing model to determine the fair value of such awards, which is recognized ratably over the three-year service period. For these TSR awards, the per unit or share fair value was estimated using the following assumptions:

Dividend Reinvestment Plan

The Company’s Dividend Reinvestment Plan (the “DRP”), among other things, provides stockholders with the opportunity to reinvest all or a portion of their cash dividends paid on the Company’s common stock in additional shares of its common stock, at a discount, determined in the Company’s sole discretion, of up to 5% from the market price (as such price is calculated pursuant to the DRP). The discount is currently being offered at 3%.

During 2025, 2024 and 2023, the Company issued approximately 31,000, 161,000 and 233,000 shares of common stock, respectively, under the DRP.

Shares Issued through the At-the-Market Equity Offering Program

The Company did not sell any shares during 2025 and 2023. During 2024, the Company sold approximately 38,000 shares for proceeds of $1,095,000, net of commissions of $22,000, and incurred offering costs of $54,000 for professional fees.

Stock Repurchase Program

The Board of Directors authorized a repurchase program pursuant to which the Company can repurchase shares of its common stock in open-market, through privately negotiated transactions or otherwise.

No shares were repurchased by the Company during 2025 and 2024.

NOTE 11 — EARNINGS PER COMMON SHARE

Basic earnings per share was determined by dividing net income allocable to common stockholders for each year by the weighted average number of shares of common stock outstanding during the applicable year. Net income is also allocated to the unvested restricted stock outstanding during each year, as the restricted stock is entitled to receive dividends and is therefore considered a participating security. As of December 31, 2025, the shares of common stock underlying the RSUs (see Note 10) are excluded from the basic earnings per share calculation, as these units are not participating securities until they vest and are issued.

Diluted earnings per share reflects the potential dilution that could occur if securities or other rights exercisable for, or convertible into, common stock were exercised or converted or otherwise resulted in the issuance of common stock that shared in the earnings of the Company.

The following table provides a reconciliation of the numerator and denominator of earnings per share calculations (amounts in thousands, except per share amounts):

Year Ended December 31,
2025 ​ ​ ​ 2024 ​ ​ ​ 2023

Beachwood, Ohio Litigation

In November 2025, in connection with the sale of a property located in Beachwood, Ohio (see Note 5), the Company entered into an agreement pursuant to which it received $1,300,000 in connection with the settlement of a lawsuit captioned Eastgate LLC, et al. v. OLP Beachwood OH LLC, which is recorded as Income on settlement of litigation on the consolidated statement of income for the year ended December 31, 2025.

NOTE 14 — COMMITMENTS AND CONTINGENCIES

The Company maintains a non-contributory defined contribution pension plan covering eligible employees. Contributions by the Company are made through a money purchase plan, based upon a percent of the qualified employees’ total salary (subject to the maximum amount allowed by law). Pension expense approximated $436,000, $431,000 and $436,000 for 2025, 2024 and 2023, respectively, and is included in General and administrative expense on the consolidated statements of income.

The Company is party to (i) leases obligating it to provide tenant improvement allowances and (ii) various legal proceedings. Management believes these allowances and proceedings are routine, incidental to the operation of the Company’s business and that such allowance payments or proceedings will not have a material adverse effect upon the Company’s consolidated financial statements taken as a whole.

NOTE 15 — INCOME TAXES

The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1983. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its ordinary taxable income to its stockholders. As a REIT, the Company generally will not be subject to corporate level federal, state and local income tax on taxable income it distributes currently to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal, state and local income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. It is management’s current intention to maintain the Company’s REIT status.

Even though the Company qualifies for taxation as a REIT, the Company is subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. As of December 31, 2025, tax returns for the calendar years 2022 through 2024 remain subject to examination by the Internal Revenue Service and various state and local tax jurisdictions. In 2025 and 2024, the Company collected refunds of $135,000 and $238,000, respectively, from Tennessee related to franchise taxes paid during 2020 through 2023, as the state amended the method of calculating such taxes, resulting in overpayments made in such years. The refunds are included in State Taxes on the consolidated statements of income for the years ended December 31, 2025 and 2024, respectively.

During 2025, 2024 and 2023, the Company did not incur any federal income tax expense. The Company does not have any deferred tax assets or liabilities at December 31, 2025 and 2024. F-33

Our Charter provides that we may issue up to 62,500,000 shares of stock, consisting of 50,000,000 shares of common stock, par value $1.00 per share, and 12,500,000 shares of preferred stock, par value $1.00 per share. We refer to our common stock and preferred stock collectively as our “capital stock.”

Common Stock

Subject to the preferential rights of any other class or series of capital stock, holders of shares of our common stock are entitled to receive distributions on such shares if, as and when authorized by our board of directors and declared by us out of assets legally available for distribution and to share ratably in our assets legally available for distribution to our stockholders in the event of our liquidation, dissolution or winding-up after payment of, or adequate provision for, all known debts and liabilities.

Subject to the preferential rights of any other class or series of capital stock, each outstanding share of our common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors. Holders of shares of common stock have no right to cumulative voting in the election of directors. Under the Charter and the Bylaws, each of our directors is elected by a majority of the votes cast by the holders of our common stock in the election of such director, except in a contested election. Pursuant to our corporate governance guidelines, any nominee for election as a director who is an incumbent director but who is not elected by the vote required by the Bylaws, and with respect to whom no successor has been elected, must promptly tender his or her offer to resign to our board of directors for its consideration. The Nominating and Corporate Governance Committee (the “Nominating Committee”) of our board of directors will consider such offer and recommend to our board of directors whether to accept the offer to resign. No later than the next regularly scheduled board meeting to be held at least ten days after the date of the election, our board of directors will decide whether to accept the offer to resign. Our board of directors will promptly and publicly disclose its decision. The nominee may address the Nominating Committee and/or our board of directors but may not be present during deliberations or voting on whether to accept the nominee’s offer to resign. If the offer to resign is not accepted, the director will continue to serve until the next annual meeting of stockholders and until the director’s successor is duly elected and qualifies or until the director’s earlier resignation or removal. The Nominating Committee and our board of directors may consider any factors they deem relevant in deciding whether to accept a director’s resignation. In a contested election, directors are elected by a plurality of the votes cast at a meeting of stockholders duly called and at which a quorum is present. An election is considered contested if, as of the date of the proxy statement for the meeting of stockholders at which directors are to be elected, there are more nominees for election than the number of directors to be elected.

Holders of shares of common stock have no preference, conversion, sinking fund, redemption, exchange, or preemptive rights to subscribe for any of our securities.

Our Charter authorizes our board of directors to take such action, in addition to the other provisions contained therein, as it deems necessary or advisable, to protect us and the interests of our stockholders by preserving our status as a REIT, including the right to redeem shares of our stock to bring the ownership of our stock into conformity with the requirements for us to qualify as a REIT. Our Charter authorizes our board of directors to refuse or prevent a transfer of shares of our capital stock to any person whose acquisition of such shares would, in the opinion of our board of directors, result in our disqualification as a REIT. In addition, any transfer of our capital stock that, if effective, would result in (i) a stockholder owning shares in excess of the ownership limit set forth in our Charter (as described under “Provisions of Maryland Law and of our Charter and Bylaws—Restrictions on Ownership and Transfer”), (ii) our shares of capital stock being owned by less than 100 persons or (iii) our company being “closely held” shall be void from the date of the purported transfer.

Pursuant to the MGCL, a corporation generally cannot (except under and in compliance with specifically enumerated provisions of the MGCL) dissolve, amend its charter, merge, sell all or substantially all of its assets, convert into another business entity, engage in a statutory share exchange or engage in similar transactions outside the ordinary course of business unless the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter, approves such action, unless a lesser percentage (but not less than a majority of all of the votes entitled to be cast on the matter) is set forth in the corporation’s charter. Our Charter provides for approval of any such action by a majority of the votes entitled to be cast in the matter.

Preferred Stock

Our Charter grants authority to our board of directors to authorize from time to time the issue, in one or more classes or series, of up to 12,500,000 shares of preferred stock, par value $1.00 per share. Our Charter also authorizes our board of directors to classify and reclassify any unissued shares of our preferred stock into one or more classes or series of preferred stock. Before authorizing the issuance of a new class or series of preferred stock, our board of directors must, subject to the provisions of the Charter regarding the restrictions on ownership and transfer of our stock, fix the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications and terms and conditions of redemption for each class or series.

These actions may be taken without stockholder approval unless such approval is required by applicable law, the terms of any other class or series of our stock or the rules of any stock exchange or automated quotation system on which any shares of our stock are listed or traded. Therefore, our board of directors could authorize the issuance of shares of preferred stock that have priority over our common stock with respect to dividends or other distributions or rights upon liquidation or the issuance of shares of common stock or preferred stock with terms and conditions that could have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price for our common stock or otherwise be in the best interest of our stockholders.

Provisions of Maryland Law and of Our Charter and Bylaws

Restrictions on Ownership and Transfer

In order for us to qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), not more than 50% in value of our outstanding shares may be owned, directly or indirectly, by five or fewer individuals (defined in the Code to include certain entities such as qualified pension plans) during the last half of a taxable year and shares must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of twelve months (or during a proportionate part of a shorter taxable year).

Because our board of directors determined that it is important for us to continue to qualify as a REIT, our Charter restricts, subject to certain exceptions, the number of shares that a person may own. These restrictions are designed to safeguard us against an inadvertent loss of REIT status—they terminate in the event the board of directors determines that it is not in our best interest to qualify as a REIT.

Pursuant to our Charter, (i) any stockholder who beneficially owned (as determined pursuant to the Charter) a total amount or value in excess of 9.9% of our capital stock on June 14, 2005 was prohibited from beneficially owning in excess of a total amount or value of our capital stock that may cause us to violate such provisions of the Code relating to REITs, and (ii) any other person was restricted from beneficially owning a total amount or value of

9.9% or more of any class or series of common stock and preferred stock of our company, which we refer to as the “ownership limit” or the “ownership limitation.” Pursuant to the attribution rules under the Code, Fredric H. Gould, vice-chairman of our board of directors, is our only stockholder that beneficially owned in excess of 9.9% of our capital stock on June 14, 2005. Therefore, except as limited by the Code and the rules and regulations promulgated thereunder, or as our board of directors may otherwise require, Mr. Gould is the only person currently permitted to own and acquire shares of our capital stock, directly or indirectly, in excess of 9.9% of total amount or value. Our board of directors has exempted from the 9.9% ownership limit the ownership by Mr. Gould’s direct and indirect heirs of shares of our stock that they inherit from him, subject to the same conditions and limitations as apply to Mr. Gould.

The stock ownership rules under the Code are complex and may cause the outstanding shares of capital stock owned by a group of related individuals or entities to be deemed to be beneficially owned by one individual or entity. Specific attribution rules apply in determining whether an individual or entity owns any class or series of common stock or preferred stock of our company. Under these rules, any shares owned by a corporation, partnership, estate or trust are deemed to be owned proportionately by such entities’ stockholders, partners, or beneficiaries. Furthermore, an individual stockholder is deemed to own any shares that are owned, directly or indirectly, by that stockholder’s brothers and sisters, spouse, parents or other ancestors, and children or other descendants. In addition, a stockholder is deemed to own any shares that he can acquire by exercising options.

As a result of these attribution rules, even though a stockholder may own less than 9.9% of a class of outstanding shares, that individual or entity may be deemed to beneficially own 9.9% or more of the class of outstanding stock, which would subject the individual or entity to the ownership limitations contained in our Charter. Our Charter provides that any attempt to acquire or transfer shares of common stock or preferred stock and any resulting transfer thereof which would result in a stockholder owning an amount that equals or exceeds the ownership limit without the consent of the board of directors shall be null and void.

In the event that the board of directors or its designees determines in good faith that a prohibited transfer has taken place or is intended, the board or its designee is authorized to take any action it deems advisable to void or to prevent the transfer. These actions include, among other things, refusing to give effect to the transfer on the books of our company, instituting legal proceedings to enjoin the transfer, redeeming the shares purported to be transferred for an amount which may be less than the price the stockholder paid for such shares, and transferring the shares by operation of law to a charitable trust. In the event the shares are transferred to a charitable trust, any dividends on such shares shall inure to such charitable trust and the trustee of such charitable trust shall be entitled to all voting rights with respect to such shares.

Our board of directors may increase or decrease the ownership limits, provided (1) any decrease may, with specified exceptions, only be made prospectively to subsequent holders and (2) any increase may only be made if, after giving effect to the increase, five or fewer beneficial stockholders could not beneficially own in the aggregate more than 49% of the outstanding shares. Prior to modification of the ownership limit, our board may require such opinions of counsel, affidavits, undertakings or agreements as it may deem necessary or advisable in order to determine or ensure our status as a REIT. In addition, our board of directors, upon receipt of a ruling from the Internal Revenue Service, an opinion of counsel that such exemption will not result in our being “closely held” or such other evidence as our board of directors may require, may exempt a person from the ownership limits on such conditions as our board of directors deems necessary in its sole discretion.

Neither the ownership restrictions described above, nor the ownership limit will be removed automatically even if the REIT provisions of the Code are changed so as no longer to contain any ownership concentration limitation or if the ownership concentration limitation is increased. Except as described above, any change in the ownership restrictions would require an amendment to our Charter. Amendments to our Charter generally require the affirmative vote of holders owning not less than a majority of the outstanding shares entitled to vote thereon. In addition to preserving our status as a REIT, the ownership restrictions and the ownership limit may have the effect of precluding an acquisition of control of our company without the approval of our board of directors.

The ownership limit could have the effect of delaying, deferring or preventing a transaction or a change in control of our company that might involve a premium price for the common shares or otherwise be in the best interest of our stockholders.

Classification of Our Board of Directors, Vacancies and Removal of Directors

Our Charter provides that our board of directors is divided into three classes. Directors of each class serve for terms ending at the third annual meeting of our stockholders and upon their successors being elected and qualifying, with the terms of each class beginning in different years.

At each annual meeting of our stockholders, successors of the class of directors whose term expires at that meeting are elected for a term ending at the third annual meeting of our stockholders and upon their successors being elected and qualifying, and the directors in the other two classes continue in office. A classified board may delay, defer or prevent a change in control or other transaction that might involve a premium over the then prevailing market price for our common stock or other attributes that our stockholders may consider desirable. In addition, a classified board could prevent stockholders who do not agree with the policies of our board of directors from replacing a majority of the board of directors for two years, except in the event of removal for cause.

Our Bylaws provide that any vacancy on the Board of Directors for any cause other than an increase in the number of directors may be filled by a majority of the remaining directors, even if such majority is less than a quorum. Any vacancy in the number of directors created by an increase in the number of directors may be filled by a majority of the entire Board of Directors. Any individual elected by our Board of Directors to fill a vacancy on the Board will serve until the next annual meeting of stockholders and until his or her successor is duly elected and qualifies.

Our Charter provides that our stockholders may only remove an incumbent director for cause, at a meeting of the stockholders duly called and at which a quorum is present, upon an affirmative vote of the majority of all of the outstanding shares entitled to vote thereon.

Indemnification

Under our Charter, we would be required to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to:

any present or former director or officer who is made or threatened to be made a party to, or witness in, a proceeding by reason of his or her service in such capacity; and

any individual who, while a director or officer of ours and at our request, serves or has served as a director, officer, trustee, member, manager, or partner of another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employee benefit plan or any other enterprise, and only if he or she is made or threatened to be made a party to, or witness in, a proceeding by reason of his or her service in such capacity.

The Charter allows us, with the approval of our board of directors, to indemnify our employees, as well as directors and officers of our predecessors, subject to the same limitations set forth in the immediately preceding paragraph.

Under the MGCL and the Charter, we must indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service in that capacity. The MGCL permits us to indemnify our present and former directors and officers, among others, against judgments, penalties, fines, settlements, and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that:

the act or omission of the director or officer was material to the matter giving rise to the proceeding and (a) was committed in bad faith or (b) was the result of active and deliberate dishonesty;

the director or officer actually received an improper personal benefit in money, property, or services; or

in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

We may not indemnify a director or officer in a suit (i) by or on our behalf in which the director or officer was adjudged liable to the corporation or (ii) in which the director or officer was adjudged liable on the basis that personal benefit was improperly received. A court may order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification, even though the director or officer did not meet the prescribed standard of conduct or was adjudged liable on the basis that personal benefit was improperly received. However, indemnification for an adverse judgment in a suit by or on behalf of the corporation, or for a judgment of liability on the basis that personal benefit was improperly received, is limited to expenses.

In addition, the MGCL permits us to advance reasonable expenses to a director or officer upon receipt of:

a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation; and

a written undertaking by the director or officer or on the director’s or officer’s behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the director or officer did not meet the standard of conduct.

Limitation of Liability

The MGCL permits the charter of a Maryland corporation to include a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages, except to the extent that (1) it is proved that the person actually received an improper benefit or profit in money, property or services, or (2) a judgment or other final adjudication is entered in a proceeding based on a finding that the person’s action, or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. Our charter provides for the elimination of the liability of our directors and officers to us or our stockholders for money damages to the maximum extent permitted by Maryland law from time to time.

Maryland Business Combination Act

Pursuant to Article IX of our Charter, we have expressly elected not to be subject to, or governed by, the MGCL’s requirements for “business combinations” between a Maryland corporation and “interested stockholders.”

Maryland Control Share Acquisition Act

Maryland law provides that “control shares” of a Maryland corporation acquired in a “control share acquisition” have no voting rights except to the extent approved by a stockholder vote. Two-thirds of the shares eligible to vote (excluding all interested shares) must vote in favor of granting the “control shares” voting rights. “Control shares” are voting shares which, if aggregated with all other shares previously acquired by the acquiring person, or in respect of which the acquiring person is able to exercise or direct the exercise of voting power, other than by revocable proxy, would entitle the acquiring person to exercise voting power of at least 10% of the voting power in electing directors.

Control shares do not include shares of stock the acquiring person is entitled to vote as a result of having previously obtained stockholder approval. A “control share acquisition” means the acquisition of control shares, subject to certain exceptions.

If a person who has made (or proposes to make) a control share acquisition satisfies certain conditions (including agreeing to pay expenses), that person may compel our board of directors to call a special meeting of stockholders to be held within 50 days to consider the voting rights of the shares. If that person makes no request for a meeting, we have the option to present the question at any stockholders’ meeting.

If voting rights are not approved at a meeting of stockholders, we may redeem any or all of the control shares (except those for which voting rights have previously been approved) for fair value. We will determine the

fair value of the shares, without regard to voting rights, as of the date of the last control share acquisition by the acquiring person or, if any meeting is held at which stockholders considered and did not approve voting rights of the control shares, as of the date of such meeting.

If voting rights for control shares are approved at a stockholders’ meeting and the acquiror becomes entitled to vote a majority of the shares of stock entitled to vote, all other stockholders may exercise appraisal rights. This means that you would be able to cause us to redeem your stock for fair value. Under the MGCL, the fair value may not be less than the highest price per share paid in the control share acquisition. Furthermore, certain limitations otherwise applicable to the exercise of appraisal rights would not apply in the context of a control share acquisition.

The control share acquisition statute would not apply to shares acquired in a merger, consolidation or share exchange if we were a party to the transaction.

Article II, Section 12 of our Bylaws exempts any acquisition by Gould Investors L.P. of our equity securities from the provisions of the control share acquisition statute. This section of our Bylaws may not be amended or repealed without the written consent of Gould Investors L.P. or approval of the holders of at least two-thirds of the outstanding shares of our capital stock.

The control share acquisition statute could have the effect of discouraging offers to acquire us and of increasing the difficulty of consummating any such offers, even if our acquisition would be in our stockholders’ best interests.

Subtitle 8

Subtitle 8 of Title 3 of the MGCL permits a Maryland corporation with a class of equity securities registered under the Exchange Act and at least three independent directors to elect to be subject, by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contrary provision in the charter or bylaws, to any or all of five provisions of the MGCL which provide, respectively, for:

a classified board;
a two-thirds vote requirement for removing a director;
--- ---

a requirement that the number of directors be fixed only by vote of the board of directors;

a requirement that a vacancy on the board be filled only by the remaining directors and for the remainder of the full term of the class of directors in which the vacancy occurred; or

a majority requirement for the calling of a special meeting of stockholders.

Through provisions in our Charter and our Bylaws unrelated to Subtitle 8, we already have a classified board.

Amendments to Our Charter

Our Charter and the MGCL provide that approval of routine matters required by the MGCL to be approved by our stockholders requires approval of a majority of the votes cast on the matter, and approval of our dissolution, merger, consolidation, share exchange or conversion, or amendments to our Charter that require approval by our stockholders, require the affirmative vote of a majority of the votes entitled to be cast on the matter.

Amendment to Our Bylaws

Our board of directors has the power to alter, modify or repeal any of our Bylaws and to make new Bylaws, except that our board may not alter, modify or repeal (1) any Bylaws made by stockholders; and (2) Section 12 of Article II of our Bylaws governing the Gould Investors L.P. exemption from the control share acquisition statute.

In addition, our stockholders have the power to alter, modify or repeal any of our Bylaws and to make new Bylaws by majority vote; however, the vote of at least two-thirds of the holders of our outstanding shares of capital stock is needed to amend or repeal the Gould Investors L.P. exemption from the control share acquisition statute, as discussed above under “Maryland Control Share Acquisition Act.”

Advance Notice of Director Nominations and New Business

The Bylaws provide that nominations of individuals for election as directors and proposals of business to be considered by stockholders at any annual meeting may be made only (1) pursuant to our notice of the meeting, (2) by or at the direction of our board of directors or (3) by any stockholder who was a stockholder of record at the record date set by our board of directors for the purpose of determining stockholders entitled to vote at the meeting, at the time of giving the notice required by our Bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each of the individuals so nominated or on such other proposed business and who has complied with the advance notice procedures of the Bylaws. Stockholders generally must provide notice to our Corporate Secretary not earlier than the 150th day or later than the close of business on the 120th day before the first anniversary of the date that our proxy statement is released to the stockholders for the preceding year’s annual meeting of stockholders.

Only the business specified in the notice of the meeting may be brought before a special meeting of stockholders. Nominations of individuals for election as directors at a special meeting of stockholders may be made only (1) by or at the direction of our board of directors, (2) by a stockholder that requested, in accordance with the procedures set forth in the Bylaws, that a special meeting be called for the purpose of electing directors, or (3) if the special meeting has been called in accordance with the Bylaws for the purpose of electing directors, by any stockholder who was a stockholder of record at the record date set by our board of directors for purposes of determining stockholders entitled to vote at the meeting, at the time of giving the notice required by the Bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the advance notice procedures of the Bylaws.  Stockholders generally must provide notice to our Corporate Secretary not earlier than the 120th day before such special meeting or later than the close of business on the 90th day before the special meeting or if later, the tenth day after the first public announcement of the date of the special meeting and the nominees proposed by our board of directors to be elected at the meeting.

A stockholder’s notice must contain certain information specified by the Bylaws about the stockholder, its affiliates and any proposed business or nominee for election as a director, including information about the economic interest of the stockholder, its affiliates, and any proposed nominee.

Exclusive Forum

The Bylaws provide that, unless we otherwise agree, (a) any derivative action or proceeding(other than actions arising under federal securities laws), (b) any action asserting a claim of breach of any duty owed by any of our directors, officers or other employees to us or to our stockholders, (c) any action asserting a claim against us or any of our directors, officers or other employees pursuant to the MGCL, the Charter or the Bylaws, (d) claims governed by the internal affairs doctrine, and (e) any Internal Corporate Claim, as such term is defined in the MGCL, must be brought in the Circuit Court for Baltimore City, Maryland, or the Supreme Court of Nassau County, New York (or, if neither such court has jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, or the United States District Court for the Eastern District of New York). These choice of forum provisions will not apply to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended, the Exchange Act, or any other claim for which federal courts have exclusive jurisdiction.

6.Forfeiture.

11.Section 83(b) Election.

12.No Segregation. Neither the Company nor any Subsidiary shall be required to segregate any cash or Shares which may at any time be represented by awards under the Plan and the Plan shall constitute an “unfunded” plan of the Company. Neither the Company nor any Subsidiary shall by any provisions of the Plan be deemed a trustee of any Shares or any other property, and the liabilities of the Company and any Subsidiary to the Holder pursuant to the Plan shall be those of a debtor pursuant to such contract obligations as are created by or pursuant to the Plan and this Agreement and the rights of the Holder or his/her beneficiary under the Plan shall be limited to those of a general creditor of the Company or the applicable Subsidiary, as the case may be.

13.Clawback Policy; Restrictions on Transfers. The Holder acknowledges and agrees that:

(a)(i) the Restricted Stock and the dividends paid thereon may be subject to recapture and/or return (before and/or after the Vesting Date) pursuant to the clawback or other similar policies as may be adopted by the Company from time-to-time or as required by law (including the requirements of a national securities exchange on which the Common Stock is then listed); and (ii) acknowledges that Incentive-Based-Compensation (as defined in the Company’s clawback effective as of October 2, 2023, as amended or supplemented from time-to-time (the “Clawback” Policy”)) may be subject to return and/or recapture pursuant to the Clawback Policy; and

(b) their ability to transfer the Shares subject to this award may be limited by applicable law (including without limitation, the Securities Act of 1933, as amended, and the requirements of the New York Stock Exchange), the Company’s Articles of Amended and Restatement, as amended from time-to-time, the Company’s Amended and Restated Bylaws, as amended from time-to-time, and the Company’s organizational and corporate governance documents as in effect from time-to-time (including without limitation, the Company’s Code of Business Conduct and Ethics and the Company’s Insider Trading Policy).

IN WITNESS WHEREOF, the parties hereto have executed this Agreement the day and year first above written.

INSIDER TRADING POLICY

Effective as of March 5, 2026

I. Purpose

This Insider Trading Policy (the “Policy”) provides guidelines with respect to transactions in the securities of One Liberty Properties, Inc. and BRT Apartments Corp. (all of the foregoing collectively referred to, unless the context otherwise requires, as “us”, “we”, “our” or the “Company”) and the handling of confidential information about us and the companies with which we engage in transactions or do business. We have adopted this Policy to promote compliance with U.S. federal and state laws that prohibit certain persons who are aware of material nonpublic information about a company from: (i) engaging in transactions in the securities of that company; or (ii) providing material nonpublic information to other persons who may trade on the basis of that information.

**II.**Statement **** of **** Policy

A. Transactions involving our Company

If you are aware of material nonpublic information (see “VII. Definition of Material Nonpublic Information.”) relating to us, you may not, directly, or indirectly through family members or other persons or entities:

1. Engage in transactions in our securities, except as otherwise (i) specified in this Policy or (ii) permitted by the Compliance Officer. See “IV. Transactions and Transfers Subject to, and Exempt from, the Policy.”

2. Recommend that others engage in transactions in our securities;
3. Disclose such information to persons outside of the Company, including, but not limited to, family, friends, business associates, and investors, unless any such disclosure:
--- ---
is permitted by the Compliance Officer:
--- ---
is disclosed to those who owe us a duty of confidentiality (e.g., our outside professionals such as our internal and external auditors and lawyers); or
--- ---
is made in accordance with our policies regarding the protection or authorized external disclosure of information regarding the Company.
--- ---
4. Assist anyone engaged in the above activities.
--- ---
B. Transactions Involving Companies with whom we do Business
--- ---

In addition, if in the course of working for us or our Affiliated Entities (as such term is defined below), you learn of material nonpublic information about a company (1) with which we or our Affiliated Entities do business, such as our or their respective vendors, suppliers and tenants, or (2) that is involved in a potential transaction or business relationship with us or our Affiliated Entities, you may not engage in transactions in that company’s securities until the information becomes public or is no longer material.

The term “Affiliated Entities” means the Company, Gould Investors L.P., BRT Apartments Corp., Majestic Property Management LLC, their respective direct and indirect subsidiaries (i.e., entities which are controlled by, directly or indirectly, the foregoing companies), and any one or more of the foregoing. (The term “controlled by” means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting securities, by contract, or otherwise).

C. Company Transactions Involving our Securities

Except as permitted by the Compliance Officer, we will not engage in transactions in our securities while aware of material nonpublic information relating to us or our securities.

III. Persons **** Subject **** to **** the **** Policy

This Policy applies to (i) all those subject to our Code of Business Conduct and Ethics, as amended from time-to-time (the “Code”) (with those subject to the Code referred to in this Policy as “you” or equivalent terms), (ii) your Family Members (as described below), (iii) your Controlled Entities, and (iv) such other persons that we (i.e., one or more of our executive officers or our Compliance Officer) designate as being subject to this Policy, such as contractors or consultants who have access to material nonpublic information (a “Designee”).

You are responsible for the transactions of your Family Members and Controlled Entities and should make them aware of the need to confer with you before they trade in our securities, and you should treat all transactions or transfers of our securities by Family Members and Controlled Entities as if the transactions were for your own account. This Policy does not, however, apply to personal securities transactions of Family Members or Controlled Entities, where the purchase or sale decision is made by a third party not controlled by, influenced by or related to you, your Family Members, or your Controlled Entities.

A. Definition of Family Members and Controlled Entities

The term “Family Members” means your family members who reside with you (including a spouse, a child, a child away at college, stepchildren, grandchildren, parents, stepparents, grandparents, siblings and in-laws), anyone else who lives in your household, and any family members who do not live in your household but whose transactions in our securities are directed by you or are subject to your influence or control, such as parents or children who consult with you before they trade in our securities.

The term “Controlled Entities” means any entities that you influence or control, including any corporations, partnerships or trusts.

IV. Transactions **** Subject **** to, and Exempt from, **** the **** Policy
A. Transactions and Transfers subject to the Policy
--- ---

This Policy applies to transactions in, and transfers of, our securities including our common stock, restricted stock awards, restricted stock units or any other type of securities that we may issue, as well as derivative securities that are not issued by us, such as exchange-traded put or call options or swaps relating to our securities. Transactions subject to this Policy include purchases, sales and bona fide gifts of our securities. Transactions that occur as a result of a person’s death are not subject to the Policy.

B. Transactions and Transfers Exempt from the Policy

This Policy does not apply to the following transactions and transfers, except as specifically noted:

1.Restricted Stock and Restricted Stock Unit Awards. This Policy does not apply to the vesting of restricted stock awards or restricted stock units (i.e., performance awards). The Policy applies, however, to any sales of restricted stock or shares underlying the restricted stock units.

2.Dividend Reinvestment Plan. This Policy does not apply to transactions involving our dividend reinvestment plan (the “DRIP”). However, your (i) election to participate in, or withdraw from, the DRIP, or increase or decrease your level of participation in the DRIP, may be unlawful if it is based on material non-public information, and (ii) sale of shares acquired pursuant to the DRIP must comply with the Policy (including the pre-approval requirement described in “Section IX – Procedures to Prevent Insider Trading – A. Pre-Clearance of All Transfers and Transactions of Securities.”)

3.Transactions Affected Pursuant to Specified Trading Plans. This policy does not apply to transactions affected pursuant to a trading plan (e.g., a trading plan that meets the requirements of Rule 10b5-1) that is approved by the Compliance Officer in his or her sole and absolute discretion (a “Trading Plan”).

4.Transactions and Transfers at the Compliance Officer’s Discretion. Because this Policy cannot address every possible transaction or transfer, the Compliance Officer, in his or her sole and absolute discretion, has the authority to determine that a proposed transaction or transfer is not subject to the Policy.

A good general rule of thumb – when in doubt, do not trade.

V. Individual **** Responsibility

You have ethical and legal obligations to maintain the confidentiality of information about us and to not engage in transactions in our securities while in possession of material nonpublic information. You must not engage in illegal trading and must avoid the appearance of improper trading. You are responsible for complying with this Policy and ensuring that any Family Member or Controlled Entity complies with this Policy. In all cases, the responsibility for determining whether you are **** in **** possession **** of **** material **** nonpublic **** information (as described under “VII – Definition of Material Non-Public Information”) rests **** with you, and **** any action on our part (including an approval of your proposed transaction by the Compliance Officer (as described under “VI - Administration of the Policy” **** and **** “IX – Procedures to Prevent Insider Trading – A. Pre-Clearance of All Transactions and Transfers of Our Securities.”) does **** not in any way constitute legal advice or insulate you from liability under applicable securities law.

**VI.**Administration **** of **** the **** Policy

The administration of this Policy is overseen by our Compliance Officer. We will advise you in writing on an annual basis as to the person(s) serving as the Compliance Officer. All determinations and interpretations by the Compliance Officer are final and not subject to further review.

**VII.**Definition **** of **** Material **** Non-public **** Information

A.Material Information.

Information is considered “material” if a reasonable investor would consider that information important in making a decision to buy, hold or sell securities. Any information that could be expected to affect a company’s stock price, whether positive or negative, should be considered material. Set forth below is a non-exclusive, non-comprehensive list of examples of information that ordinarily would be regarded as material:

Projections of future earnings or losses, or other earnings guidance;
Changes to previously announced earnings guidance, or the decision to suspend earnings guidance;
--- ---
A pending or proposed merger, acquisition or tender offer;
--- ---
A pending or proposed acquisition or disposition of a significant asset;
--- ---
A pending or proposed joint venture;
--- ---
Significant related party transactions;
--- ---
A change in dividend policy, the declaration of a stock split, or an offering of additional securities;
--- ---
Bank borrowings or other financing transactions out of the ordinary course;
--- ---
The establishment of a repurchase program for our securities;
--- ---
A change in senior management;
--- ---
A change in auditors or notification that the auditor’s reports may no longer be relied upon;
--- ---
Pending or threatened significant litigation, or the resolution of such litigation;
--- ---
Impending bankruptcy or the existence of severe liquidity problems;
--- ---
The gain or loss of a significant tenant; or
--- ---
A significant cybersecurity incident, such as a data breach, or any other significant disruption in our operations or the loss, potential loss, breach or unauthorized access of our property or assets, whether at our facilities or through our information technology infrastructure.
--- ---

B.When Information is Considered Public.

Information that has not been widely disclosed to the public is generally considered to be nonpublic information. Information generally would be considered public if it is available on the SEC’s website or if it has been disclosed through the newswire services, broadcast on widely-available radio or television program, published in a widely-available newspaper, magazine or news website. Publication of information solely on our website is not, by itself, considered to be publicly disclosed.

Once information is widely disseminated, it is still necessary to provide the public with sufficient time to absorb the information. See “IXProcedures to Prevent Insider TradingB. Open Window Period” for further information regarding the waiting period following the dissemination of information. Depending on the particular circumstances, the Compliance Officer may determine that a longer or shorter period should apply to the release of specific material nonpublic information.

**VIII.**Pledged Securities

We do not prohibit the pledging of our securities (including the use of our securities to collateralize a margin loan). Nonetheless, you should be aware your sale of our securities pursuant to a margin call or other foreclosure may occur at the time you are aware of material non-public information, or during a period that does not qualify as an Open Window Period (as described under See “IXProcedures to Prevent Insider TradingB. Open Window Period”), and such sale may violate this Policy.

**IX.**Procedures to Prevent Insider Trading

We established the following procedures to assist in the administration of this Policy:

A. Pre-Clearance of all Transactions and Transfers of our Securities. You, your Family Members, your Controlled Entities and the persons designated by the Compliance Officer as being subject to these procedures, may not transact (e.g., purchase or sell) or transfer (e.g., gifts or transfers from a regular investment account to a Keogh account) any of our securities without first obtaining pre-clearance of the transaction or transfer from the Compliance Officer. You should request pre-clearance (either orally or in writing (including email)) from the Compliance Officer at least two business days in advance of the proposed transaction. The Compliance Officer is under no obligation to approve a transaction or transfer submitted for pre-clearance and may determine not to permit the transaction or transfer. If your request to engage in the transaction is denied, you should refrain from such activity, and should not inform any other person of the restriction.

When you request pre-clearance, you should carefully consider whether you may be aware of any material nonpublic information about us, and should describe fully those circumstances to the Compliance Officer. The Compliance Officer, in his or her sole and absolute discretion, (i) may request additional information and/or documentation from you with respect to such matters as he or she deems appropriate, and (ii) will determine the period and the other terms and conditions, if any, under which the proposed transaction may be completed.

B. Open Window Period. You, your Family Members and your Controlled Entities, may only conduct any transactions (other than as permitted by this Policy) involving our securities during an “Open Window Period.” The Open Window Period will be determined from time-to-time by the Compliance Officer (and you should consult with the Compliance Officer as to the scope of such period); generally, Open Window Periods:

begin on the second full trading (i.e., a day on which the New York Stock Exchange is open for trading) day immediately following the date that our Quarterly Report on Form 10-Q is accepted by the SEC,

begin on the third full trading business day immediately following the date that our Annual Report on Form 10-K (“Annual Report”), is accepted by the SEC, and

end seven (7) days after the close of the next fiscal quarter.

For example, if we file our Annual Report on March 9, 2026 (and such filing is accepted by the SEC by 5:30 p.m. on such date), you generally will be entitled to transact in our securities beginning March 12, 2026 through April 7, 2026.

C. Event-Specific Restricted Periods. From time to time, an event may occur that is material to us and is known by only a few people. So long as the event remains material and nonpublic, you may not engage in transactions in our securities. In that situation, the Compliance Officer may restrict you from trading in our securities, without disclosing the reason for the restriction, and you should not discuss with others the imposition of such restriction.

D. Broker Interface Procedures. If you are a director or executive officer (i.e., those individuals filing Form 4’s), you must notify the brokerage firm at which your securities are held that you are a “control person” with respect to our securities and such brokerage firm must obtain the approval of our Compliance Officer before affecting your transactions in our securities. Your securities in our Company may only be held at a brokerage firm that agrees (and has the requisite systems in place) to maintain such restrictions (including the ability and willingness to file any Form 144); you agree to provide the Compliance Officer, upon request, with such information as he or she deems appropriate to ensure that such brokerage firm will maintain such restrictions and comply with other appropriate requirements.

**X.**Limitation on Liability

Neither we, our employees (including our “shared employees”) or the Compliance Officer will have any liability for any delay in reviewing, or refusal of, a Trading Plan or a request for pre-clearance of a transaction or transfer.  Notwithstanding any review of a Trading Plan or pre-clearance of a transaction or transfer, neither we, our employees (including our “shared employees”) nor the Compliance Officer assumes any liability for the legality or consequences of such trading plan, transaction or transfer to the person engaging in or adopting such trading plan, transaction or transfer.

**XI.**Post-Termination **** Transactions

This Policy (other than the pre-clearance requirements) continues to apply to transactions in our securities even after your relationship with us ends. If you are in possession of material nonpublic information when your relationship with us ends, you may not engage in transactions in our securities until that information has become public or is no longer material.

**XII.**Consequences of **** Violations

The purchase or sale of securities while aware of material nonpublic information, or the disclosure of material nonpublic information to others who then engage in transactions in our securities, is prohibited by the federal and state laws. Insider trading violations are pursued vigorously by governmental authorities. Punishment for insider trading violations is severe, and could include significant fines and imprisonment.

In addition, your failure to comply with this Policy may subject you to sanctions imposed by us, including dismissal for cause, whether or not your failure to comply results in a violation of law. Needless to say, a violation of law, or even an SEC investigation that does not result in prosecution, can tarnish a person’s reputation and irreparably damage a career.

XIII. Assistance

If you have questions about this Policy or its application to any proposed transaction you may seek additional guidance from the Compliance Officer. On an annual basis, we will notify you as to the person(s) serving as the Compliance Officer.

XIV. Certification

All persons subject to this Policy must certify their understanding of, and intent to comply with, this Policy.
