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. Further, information regarding historical rent collections should not serve as an indication of future rent collections.

The following factors, among others, could cause actual results to differ materially from those set forth in the forward-looking statements:
the risk of rising interest rates, including that our borrowing costs may increase and we may be unable to refinance our debt obligations on favorable terms or at all;
the risk of inflation, including that our operating costs, such as insurance premiums, utilities, real estate taxes and 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;
the extent to which the ongoing COVID-19 pandemic or any future pandemic or outbreak of a highly infectious or contagious disease or fear of such pandemics or outbreaks impacts our business, operating results, financial condition and prospects, which is highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the COVID-19 pandemic and its impact on the U.S. economy and potential changes in tenant behavior that could adversely affect the use of and demand for office space;
our ability to acquire new properties and sell non-core assets on favorable terms and in a timely manner, or at all;
our ability to comply with the terms of our credit agreements or to meet the debt obligations on certain of our properties;
our ability to access the capital markets to raise additional equity or refinance maturing debt on favorable terms 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 tenant defaults on their lease obligations, which are heightened due to our focus on single tenant properties;
our ability to renew leases with existing tenants or re-let space to new tenants on favorable terms or at all;
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 associated with our joint venture with an affiliate of Arch Street Capital Partners and any potential future equity investments;
our ability to close pending real estate transactions, which may be subject to conditions that are outside of our control;
risks associated with acquisitions, including the integration of the office portfolios of Realty Income Corporation (“Realty Income”) and VEREIT Inc. into Orion;
Realty Income’s inability or failure to perform under the various transaction agreements effecting the Separation and the Distribution;
risks associated with the fact that we have a limited operating history and our future performance is difficult to predict;
our properties may be subject to impairment charges;

Q1 2022 SUPPLEMENTAL INFORMATION
Definitions
(unaudited, in thousands, except share and per share data)
Annualized Base Rent is the monthly aggregate cash amount charged to tenants under our leases (including monthly base rent receivables and certain contractually obligated reimbursements by our tenants), as of the final date of the applicable period, multiplied by 12, including the Company's pro rata share of such amounts related to the Unconsolidated Joint Venture. Annualized Base Rent is not indicative of future performance.

Cash Cap Rate for real estate properties equals the estimated future 12-month Cash NOI, excluding any rent concessions or abatements, at the time of the acquisition or disposition divided by the purchase or sale price. For any properties acquired or disposed of as a portfolio, the amount presented represents the portfolio cash cap rate. For certain properties, the Cash Cap Rate may be equal to future 12-month contractual rental revenue, excluding any rent concessions or abatements, divided by the purchase price or sale price, as the majority of the Company's properties are subject to Net Leases.

CPI refers to a lease in which base rent is adjusted based on changes in a consumer price index.
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 or 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 pro rata 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 acquisition-related expenses and transaction costs. 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 pro rata 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, as computed in accordance with 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.

Occupancy Rate equals the sum of Leased Square Feet divided by Rentable Square Feet and includes the Company's pro rata share of such amounts related to the Unconsolidated Joint Venture, in each case, as of an applicable date.

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) the sum of (i) Interest Expense, excluding non-cash amortization and (ii) secured debt principal amortization on Adjusted Principal Outstanding, divided by (b) Adjusted EBITDA. 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 initial 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.

Q1 2022 SUPPLEMENTAL INFORMATION
Definitions (cont.)
(unaudited, in thousands, except share and per share data)
Flat refers to a lease that requires equal rent payments, with no contractual increases, throughout the initial 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, as well as certain non-cash items such as amortization of deferred financing costs, amortization of above market leases and deferred lease incentives, net of amortization of below market lease liabilities, straight-line rental revenue, equity-based compensation, equity in income or losses of the Unconsolidated Joint Venture and our pro rata 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 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 a REIT. FFO is not equivalent to our net income or loss as determined under GAAP.
Nareit defines FFO as net income or 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 pro rata 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 non-recurring or infrequent items such as acquisition-related expenses, transaction costs and gains or losses on extinguishment of swaps and/or debt. Core FFO allows for a comparison of the performance of our operations with other publicly-traded REITs, as Core FFO, or an equivalent measure, is routinely reported by publicly-traded REITs, and we believe 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 defined by 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 pro rata 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 in accordance with 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.

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 pro rata 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 in accordance with 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.

(unaudited, in thousands, except share and per share data)
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 pro rata 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 in accordance with 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 pro rata share of the Unconsolidated Joint Venture's cash and cash equivalents. 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, acquisition-related expenses and transaction costs. Cash NOI excludes the impact of certain GAAP adjustments included in rental revenue, such as straight-line rent adjustments and amortization of above-market intangible lease assets and below-market lease intangible liabilities. Cash NOI includes the pro rata 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.
