Forward-Looking Statements Information set forth herein includes “forward-looking statements” which reflect the Company's expectations and projections regarding future events and plans, future financial condition, results of operations, liquidity and business, including leasing and occupancy, acquisitions, dispositions, rent receipts, expected borrowings and financing costs and the payment of future dividends. Generally, the words "anticipates," "assumes," "believes," "continues," "could," "estimates," "expects," "goals," "intends," "may," "plans," "projects," "seeks," "should," "targets," "will," "guidance," variations of such words and similar expressions identify forward-looking statements. These forward-looking statements are based on information currently available to the Company and involve a number of known and unknown assumptions and risks, uncertainties and other factors, which may be difficult to predict and beyond the Company's control, that could cause actual events and plans or could cause the Company's business, financial condition, liquidity and results of operations to differ materially from those expressed or implied in the forward-looking statements. These factors include, among other things, those discussed below. Information regarding historical rent collections should not serve as an indicator of future rent collections. We disclaim any obligation to publicly update or revise any forward-looking statements, whether as a result of changes in underlying assumptions or factors, new information, future events or otherwise, except as may be required by law. The following are some, but not all, of the assumptions, risks, uncertainties and other factors that could cause the Company's actual results to differ materially from those presented in the forward-looking statements: • the risk of rising interest rates, including that our borrowing costs may increase and we may be unable to extend or refinance our debt obligations on favorable terms and in a timely manner, or at all, including our credit facility revolver which has no remaining extension options; • the risk of inflation, including that our operating costs, such as insurance premiums, utilities, real estate taxes, capital expenditures and repair and maintenance costs, may rise; • conditions associated with the global market, including an oversupply of office space, tenant credit risk and general economic conditions and geopolitical conditions; • uncertainties regarding future actions that may be taken by Kawa Capital Management, Inc. in furtherance of its unsolicited proposal; • the risk that recent changes in United States trade policy and the imposition of new tariffs continue to create disruption in macroeconomic conditions and could adversely impact our lenders, tenants and prospective tenants, and cause them to reduce or decline to do business with us or fail to meet their obligations to us; • the extent to which changes in workplace practices and office space utilization, including remote and hybrid work arrangements, and changes in government budgetary priorities, will continue and the impact that may have on demand for office space at our properties; • our ability to acquire new properties, convert certain vacant properties to multi-tenant use and sell non-core assets on favorable terms and in a timely manner, or at all; • risks associated with acquisitions, including the risk that we may not be in a position, or have the opportunity in the future, to make suitable property acquisitions on advantageous terms and/or that such acquisitions will fail to perform as expected; • our assumptions concerning tenant utilization and renewal probability of dedicated use assets, and our ability to successfully execute on our strategy to shift our portfolio concentration over time away from traditional office properties, towards more dedicated use assets; • our ability to comply with the terms of our credit agreements or to meet the debt obligations on our properties; • our ability to access the capital markets to raise additional equity or refinance maturing debt on favorable terms and in a timely manner, or at all; • changes in the real estate industry and in performance of the financial markets and interest rates and our ability to effectively hedge against interest rate changes; • the risk of tenants defaulting on their lease obligations, which is heightened due to our focus on single-tenant properties; • our ability to renew leases with existing tenants or re-let vacant space to new tenants on favorable terms and in a timely manner, or at all; Q3 2025 SUPPLEMENTAL INFORMATION Orion Properties Inc. | WWW.ONLREIT.COM | 4

• uncertainty as to whether the new Department of Government Efficiency, or DOGE, will lead to efforts by the General Services Administration to exercise termination options under or otherwise seek to terminate our leases with the United States Government or make it more likely the United States Government terminates the applicable lease at lease expiration; • the cost of rent concessions, tenant improvement allowances and leasing commissions; • the potential for termination of existing leases pursuant to tenant termination rights; • the amount, growth and relative inelasticity of our expenses; • risks associated with the ownership and development of real property; • risks accompanying our investment in and the management of OAP/VER Venture, LLC (the “Arch Street Joint Venture”), our unconsolidated joint venture, in which we hold a non-controlling ownership interest, including that our joint venture partner may not be able to contribute its share of capital requirements; • our ability to close pending real estate transactions, which may be subject to conditions that are outside of our control; • we may change our dividend policy at any time, and therefore the amount, timing and continued payment of dividends are not assured; • our properties may be subject to impairment charges; • risks resulting from losses in excess of insured limits or uninsured losses; • risks associated with the potential volatility of our common stock; and • the risk that we may fail to maintain our income tax qualification as a real estate investment trust. Additional factors that may affect future results are contained in the Company's filings with the SEC, which are available on the SEC’s website at www.sec.gov. The Company disclaims any obligation to publicly update or revise any forward-looking statements, whether as a result of changes in underlying assumptions or factors, new information, future events or otherwise, except as required by law.

Company Overview (unaudited) Orion is a real estate company incorporated in the state of Maryland on July 1, 2021, which has elected to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes, commencing with its initial taxable year ended December 31, 2021. Orion is an internally managed REIT engaged in the ownership, acquisition and management of a diversified portfolio of office properties in high-quality suburban markets across the United States and leased primarily on a single-tenant net lease basis to creditworthy tenants. The Company's portfolio is comprised of traditional office properties, as well as governmental, medical office, flex/laboratory and R&D and flex/industrial properties. On March  5, 2025, the Company changed its name from Orion Office REIT Inc. to Orion Properties Inc. to better describe its broader investment strategy to shift its portfolio concentration over time away from traditional office properties, towards more dedicated use assets that have an office component. The Company defines dedicated use assets as those that include a substantial specialized use component such as government, medical, laboratory and research and development, and flex operations, and would therefore not be considered traditional office properties. As of September  30, 2025, Orion owned and operated a portfolio of 63 Operating Properties with an aggregate of 7.4 million leasable square feet located within 28 states. In addition, Orion owns a 20% equity interest in one Unconsolidated Joint Venture with an affiliate of Arch Street Capital Partners, which as of September  30, 2025, owned a portfolio of six properties with an aggregate of 1.0 million leasable square feet located in six states. As of September  30, 2025, approximately 67.0% of Annualized Base Rent was from Investment-Grade Tenants and 33.9% was from properties deemed to be dedicated use assets, the Occupancy Rate was 72.8%, or 74.5% adjusted for five Operating Properties that are currently under agreements to be sold or have been sold following September 30, 2025, and the Weighted Average Remaining Lease Term was 5.8 years. Orion's Annualized Base Rent as of September  30, 2025 was approximately $113.9  million. The top tenants, tenant industries and geographic locations of the Company's Operating Properties are outlined in the following sections: "Tenants Comprising Over 1% of Annualized Base Rent," "Tenant Industry Diversification," and "Operating Property Geographic Diversification," respectively. Tenants, Trademarks and Logos Orion is not affiliated or associated with, is not endorsed by, does not endorse, and is not sponsored by or a sponsor of the tenants or of their products or services pictured or mentioned. The names, logos and all related product and service names, design marks and slogans are the trademarks or service marks of their respective companies.

___________________________________ (1) Interest rate for variable rate debt represents the interest rate in effect as of September 30, 2025. (2) Includes $355.0 million securitized mortgage loan secured by 19 of the Company's properties (the "CMBS Loan") which bears interest at a fixed rate of 4.971% and matures on February 11, 2027. Also includes $18.0 million fixed rate mortgage loan secured by the San Ramon, California property (the "San Ramon Loan") which bears interest at a fixed rate of 5.90% and matures on December 1, 2031. (3) Under the credit facility revolver, these borrowings which are secured only by a pledge of equity interests of certain of the Company's subsidiaries are treated as unsecured indebtedness. The Company's otherwise unencumbered properties are part of the unencumbered property pool under the credit facility revolver and therefore, generally are not available to simultaneously serve as collateral under other borrowings. (4) Liquidity represents cash and cash equivalents of $33.0 million, including the Company's proportionate share of cash from the Unconsolidated Joint Venture, as well as $240.0 million available capacity on the Company's credit facility revolver as of September 30, 2025. (5) Modified Net Debt is calculated as Net Debt less restricted cash and the Company's proportionate share of restricted cash from the Unconsolidated Joint Venture of $30.1 million and $1.6 million, respectively, as of September  30, 2025. Beginning in 2026, the Company intends to modify its definition and calculation of Net Debt to add restricted cash and the Company's proportionate share of restricted cash from the Unconsolidated Joint Venture to the amounts that reduce the Company's Adjusted Principal Outstanding under debt obligations.

There was $110.0 million outstanding on the credit facility revolver as of September 30, 2025 and it is a variable rate facility with the interest rate determined, at the election of the borrower, on the basis of Daily Simple SOFR, Term SOFR or a base rate, in the case of a SOFR loan, plus 3.35%, and in the case of a base rate loan, plus 2.25%. However, the Company entered into interest rate collar agreements on a total notional amount of $60.0 million to hedge against interest rate volatility on the credit facility revolver. Under the agreements, the benchmark rate for the credit facility revolver floated between no higher than 5.50% and now lower than 4.20% on $25.0 million, and no higher than 5.50% and no lower than 4.035% on $35.0 million, effective from November 13, 2023 until May 12, 2025. Upon the scheduled expiration of the interest rate collar agreements, the Company entered into a new interest rate collar agreement to hedge against interest rate volatility on the credit facility revolver. Under the agreement, the benchmark rate for the credit facility revolver will float between no higher than 4.29% and no lower than 3.28% on a total notional amount of $75.0 million, effective from May 12, 2025 to May 12, 2026. (2) Includes $355.0 million securitized mortgage loan secured by 19 of the Company's properties (the "CMBS Loan") which bears interest at a fixed rate of 4.971% and matures on February 11, 2027. Also includes $18.0 million fixed rate mortgage loan secured by the San Ramon, California property (the "San Ramon Loan") which bears interest at a fixed rate of 5.90% and matures on December 1, 2031. (3) The Unconsolidated Joint Venture mortgages payable mature on November 27, 2025. During September 2025, the Arch Street Joint Venture exercised the remaining option to extend the maturity date of the mortgage notes until November 27, 2026, and the lenders are working to confirm all extension conditions are met, including a maximum loan-to-value of 60% which may require the Arch Street Joint Venture to partially repay the mortgage notes to satisfy this condition. The Unconsolidated Joint Venture mortgages payable have a variable interest rate which is determined, at the election of the borrower, on the basis of Daily Simple SOFR or a base rate, in the case of a SOFR loan, plus a spread of 2.60%, and in the case of a base rate loan, plus a spread of 0.50%. The Unconsolidated Joint Venture entered into interest rate cap agreements to hedge against interest rate volatility on the mortgages payable. Under the agreements, the benchmark rate for the mortgages payable will not exceed 5.50%, effective from November 27, 2024 until November 27, 2025. (4) Interest rate for variable rate debt represents the interest rate in effect as of September 30, 2025.

Annualized Base Rent is the monthly aggregate cash amount charged to tenants under our leases (including monthly base rent receivables and certain fixed contractually obligated reimbursements by our tenants), as of the final date of the applicable period, multiplied by 12, including the Company's proportionate share of such amounts related to the Unconsolidated Joint Venture. Annualized Base Rent is not indicative of future performance. Average Capitalization Rate represents annualized average estimated Cash NOI of the property over the tenant's lease term divided by gross purchase or sale price, except that for certain triple and double net lease properties, the Average Capitalization Rate represents annualized average estimated cash rental revenue of the property over the tenant’s lease term divided by gross purchase or sale price. Cash Capitalization Rate represents next 12 full months estimated Cash NOI of the property divided by gross purchase or sale price, except that for certain triple and double net lease properties, the Cash Capitalization Rate represents next 12 full months estimated cash rental revenue of the property divided by gross purchase or sale price. CPI refers to a lease in which base rent is adjusted based on changes in a consumer price index. Credit Rating of a tenant refers to the Standard & Poor's or Moody's credit rating and such rating also may reflect the rating assigned by Standard & Poor's or Moody's to the lease guarantor or the parent company as applicable. Double Net Lease ("NN") is a lease under which the tenant agrees to pay all operating expenses associated with the property (e.g., real estate taxes, insurance, maintenance), but excludes some or all major repairs (e.g., roof, structure, parking lot, in each case, as further defined in the applicable lease). Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate ("EBITDAre") and Adjusted EBITDA Due to certain unique operating characteristics of real estate companies, as discussed below, the National Association of Real Estate Investment Trusts, Inc. ("Nareit"), an industry trade group, has promulgated a supplemental performance measure known as Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate. Nareit defines EBITDAre as net income (loss) computed in accordance with GAAP, adjusted for interest expense, income tax expense (benefit), depreciation and amortization, impairment write-downs on real estate, gains or losses from disposition of property and our proportionate share of EBITDAre adjustments related to the Unconsolidated Joint Venture. We calculated EBITDAre in accordance with Nareit's definition described above. In addition to EBITDAre, we use Adjusted EBITDA as a non-GAAP supplemental performance measure to evaluate the operating performance of the Company. Adjusted EBITDA, as defined by the Company, represents EBITDAre, modified to exclude non-routine items such as transaction related expenses. We also exclude certain non-cash items such as impairments of intangible and right of use assets, gains or losses on derivatives, gains or losses on the extinguishment or forgiveness of debt, amortization of intangibles, above-market lease assets and deferred lease incentives, net of amortization of below-market lease liabilities and our proportionate share of Adjusted EBITDA adjustments related to the Unconsolidated Joint Venture. Management believes that excluding these costs from EBITDAre provides investors with supplemental performance information that is consistent with the performance models and analysis used by management, and provides investors a view of the performance of our portfolio over time. Therefore, EBITDAre and Adjusted EBITDA should not be considered as an alternative to net income (loss), as determined under GAAP. The Company uses Adjusted EBITDA as one measure of its operating performance when formulating corporate goals and evaluating the effectiveness of the Company's strategies. EBITDAre and Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Enterprise Value equals the sum of the Implied Equity Market Capitalization and Net Debt, in each case, as of an applicable date. Fixed Charge Coverage Ratio is (a) Adjusted EBITDA divided by (b) the sum of (i) Interest Expense, excluding non-cash amortization and (ii) secured debt principal amortization on Adjusted Principal Outstanding. Management believes that Fixed Charge Coverage Ratio is a useful supplemental measure of our ability to satisfy fixed financing obligations. Fixed Dollar or Percent Increase refers to a lease that requires contractual rent increases during the term of the lease agreement. A Fixed Dollar or Percent Increase lease may include a period of free rent at the beginning or end of the lease.

Flat refers to a lease that requires equal rent payments, with no contractual increases, throughout the term of the lease agreement. A Flat lease may include a period of free rent at the beginning or end of the lease. Funds Available for Distribution ("FAD") Funds available for distribution, as defined by the Company, represents Core FFO, as defined below, modified to exclude capital expenditures and leasing costs, as well as certain non-cash items such as amortization of above market leases, net of amortization of below market lease liabilities, straight-line rental revenue, amortization of the Unconsolidated Joint Venture basis difference and our proportionate share of FAD adjustments related to the Unconsolidated Joint Venture. Management believes that adjusting these items from Core FFO provides investors with supplemental performance information that is consistent with the performance models and analysis used by management and provides useful information regarding the Company's ability to fund its dividend. However, not all REITs calculate FAD and those that do may not calculate FAD the same way, so comparisons with other REITs may not be meaningful. FAD should not be considered as an alternative to net income (loss) or cash flow provided by (used in) operating activities as determined under GAAP. Nareit Funds from Operations ("Nareit FFO" or "FFO") and Core Funds from Operations ("Core FFO") Due to certain unique operating characteristics of real estate companies, as discussed below, Nareit has promulgated a supplemental performance measure known as FFO, which we believe to be an appropriate supplemental performance measure to reflect the operating performance of the Company. FFO is not equivalent to our net income (loss) as determined under GAAP. Nareit defines FFO as net income (loss) computed in accordance with GAAP adjusted for gains or losses from disposition of real estate assets, depreciation and amortization of real estate assets, impairment write-downs on real estate, and our proportionate share of FFO adjustments related to the Unconsolidated Joint Venture. We calculate FFO in accordance with Nareit's definition described above. In addition to FFO, we use Core FFO as a non-GAAP supplemental financial performance measure to evaluate the operating performance of the Company.  Core FFO, as defined by the Company, excludes from FFO items that we believe do not reflect the ongoing operating performance of our business such as transaction related expenses, amortization of deferred financing costs, amortization of deferred lease incentives, net, equity-based compensation, amortization of premiums and discounts on debt, net and gains or losses on extinguishment of swaps and/or debt, and our proportionate share of Core FFO adjustments related to the Unconsolidated Joint Venture. We believe that FFO and Core FFO allow for a comparison of the performance of our operations with other publicly-traded REITs, as FFO and Core FFO, or a substantially similar measure, are routinely reported by publicly-traded REITs, each adjust for items that we believe do not reflect the ongoing operating performance of our business and we believe are often used by analysts and investors for comparison purposes. For all of these reasons, we believe FFO and Core FFO, in addition to net income (loss), as determined under GAAP, are helpful supplemental performance measures and useful in understanding the various ways in which our management evaluates the performance of the Company over time. However, not all REITs calculate FFO and Core FFO the same way, so comparisons with other REITs may not be meaningful. FFO and Core FFO should not be considered as alternatives to net income (loss) and are not intended to be used as a liquidity measure indicative of cash flow available to fund our cash needs. Neither the SEC, Nareit, nor any other regulatory body has evaluated the acceptability of the exclusions used to adjust FFO in order to calculate Core FFO and its use as a non-GAAP financial performance measure. GAAP is an abbreviation for generally accepted accounting principles in the United States. Gross Lease is a lease under which the landlord is responsible for all expenses associated with the property (e.g., real estate taxes, insurance, maintenance and repairs).

Gross Real Estate Investments represent total gross real estate and related assets of Operating Properties and the Company's proportionate share of such amounts related to properties owned by the Unconsolidated Joint Venture, net of gross intangible lease liabilities. Gross Real Estate Investments should not be considered as an alternative to the Company's real estate investments balance as determined under GAAP or any other GAAP financial measures and should only be considered together with, and as a supplement to, the Company's financial information prepared in accordance with GAAP. The following table shows a reconciliation of Gross Real Estate Investments to the amounts presented in accordance with GAAP on the balance sheets for the periods presented (in thousands): September 30, 2025 June 30, 2025 March 31, 2025 December 31, 2024 September 30, 2024 Total real estate investments, at cost - as reported $ 1,174,249 $ 1,263,600 $ 1,281,892 $ 1,282,452 $ 1,324,778 Adjustments: Gross intangible lease assets 253,127 275,560 278,405 284,108 292,481 Gross intangible lease liabilities (38,660) (38,660) (38,660) (45,473) (46,411) Non-Operating Properties total real estate investments, at cost (11,113) (11,113) (11,113) (11,113) (11,113) Proportionate share of Unconsolidated Joint Venture Gross Real Estate Investments 46,092 46,046 46,043 45,588 45,565 Gross Real Estate Investments $ 1,423,695 $ 1,535,433 $ 1,556,567 $ 1,555,562 $ 1,605,300 GSA CPI refers to a General Services Administration ("GSA") lease that includes a contractually obligated operating cost component of rent which is adjusted annually based on changes in a consumer price index. Implied Equity Market Capitalization equals shares of common stock outstanding as of an applicable date, multiplied by the closing sale price of the Company's stock as reported on the New York Stock Exchange on such date. Industry is derived from the Global Industry Classification Standard ("GICS") Methodology that was developed by Morgan Stanley Capital International ("MSCI") in collaboration with S&P Dow Jones Indices to establish a global, accurate, complete and widely accepted approach to defining industries and classifying securities by industry. Interest Coverage Ratio equals Adjusted EBITDA divided by Interest Expense, excluding non-cash amortization. Management believes that Interest Coverage Ratio is a useful supplemental measure of our ability to service our debt obligations. Interest Expense, excluding non-cash amortization is a non-GAAP measure that represents interest expense incurred on the outstanding principal balance of our debt and the Company's proportionate share of the Unconsolidated Joint Venture's interest expense incurred on its outstanding principal balance. This measure excludes the amortization of deferred financing costs, premiums and discounts, which is included in interest expense in accordance with GAAP. Interest Expense, excluding non-cash amortization should not be considered as an alternative to the Company's interest expense as determined under GAAP or any other GAAP financial measures and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP.

The following table shows a reconciliation of Interest Expense, excluding non-cash amortization to interest expense presented in accordance with GAAP on the statements of operations for the periods presented (in thousands): Three Months Ended September 30, 2025 June 30, 2025 March 31, 2025 December 31, 2024 September 30, 2024 Interest expense, net - as reported $ 7,880 $ 8,016 $ 8,156 $ 8,263 $ 8,170 Adjustments: Amortization of deferred financing costs and other non-cash charges (933) (922) (912) (928) (920) Proportionate share of Unconsolidated Joint Venture Interest Expense, excluding non-cash amortization 516 518 494 464 481 Interest Expense, excluding non-cash amortization $ 7,463 $ 7,612 $ 7,738 $ 7,799 $ 7,731 Investment-Grade Tenants are those with a Credit Rating of BBB- or higher from Standard & Poor’s or a Credit Rating of Baa3 or higher from Moody’s. The ratings may reflect those assigned by Standard & Poor’s or Moody’s to the lease guarantor or the parent company, as applicable. Leased Rate equals the sum of Leased Square Feet divided by Rentable Square Feet and includes the Company's proportionate share of such amounts related to the Unconsolidated Joint Venture, in each case, as of an applicable date. Leased Square Feet is Rentable Square Feet leased for which revenue recognition has commenced in accordance with GAAP and signed leases for vacant space with future commencement dates and includes such amounts related to the Unconsolidated Joint Venture. Modified Gross Lease is a lease under which the landlord is responsible for most expenses associated with the property (e.g., real estate taxes, insurance, maintenance and repairs), but passes through some operating expenses to the tenant. Month-to-Month refers to a lease that is outside of the contractual lease expiration, but the tenant has not vacated and continues to pay rent which may also include holdover rent if applicable. Net Debt, Principal Outstanding and Adjusted Principal Outstanding  Principal Outstanding is a non-GAAP measure that represents the Company's outstanding principal debt balance, excluding certain GAAP adjustments, such as premiums and discounts, financing and issuance costs, and related accumulated amortization. Adjusted Principal Outstanding includes the Company's proportionate share of the Unconsolidated Joint Venture's outstanding principal debt balance. We believe that the presentation of Principal Outstanding and Adjusted Principal Outstanding, which show our contractual debt obligations, provides useful information to investors to assess our overall financial flexibility, capital structure and leverage. Principal Outstanding and Adjusted Principal Outstanding should not be considered as alternatives to the Company's consolidated debt balance as determined under GAAP or any other GAAP financial measures and should only be considered together with, and as a supplement to, the Company's financial information prepared in accordance with GAAP. Net Debt is a non-GAAP measure used to show the Company's Adjusted Principal Outstanding, less all cash and cash equivalents and the Company's proportionate share of the Unconsolidated Joint Venture's cash and cash equivalents. Beginning in 2026, the Company intends to modify its definition and calculation of Net Debt to add restricted cash and the Company's proportionate share of restricted cash from the Unconsolidated Joint Venture to the amounts that reduce the Company's Adjusted Principal Outstanding under debt obligations. We believe that the presentation of Net Debt provides useful information to investors because our management reviews Net Debt as part of its management of our overall liquidity, financial flexibility, capital structure and leverage.

Net Operating Income ("NOI") and Cash NOI NOI is a non-GAAP performance measure used to evaluate the operating performance of a real estate company. NOI represents total revenues less property operating expenses and excludes fee revenue earned for services to the Unconsolidated Joint Venture, impairment, depreciation and amortization, general and administrative expenses, and transaction related expenses. Cash NOI excludes the impact of certain GAAP adjustments included in rental revenue, such as straight-line rental revenue, amortization of above-market intangible lease assets and below-market lease intangible liabilities, and amortization of deferred lease incentives. Cash NOI includes the proportionate share of such amounts from properties owned by the Unconsolidated Joint Venture. It is management's view that NOI and Cash NOI provide investors relevant and useful information because it reflects only income and operating expense items that are incurred at the property level and presents them on an unleveraged basis. NOI and Cash NOI should not be considered as an alternative to operating income in accordance with GAAP. Further, NOI and Cash NOI may not be comparable to similarly titled measures of other companies.
