- Closed Credit Agreement Amendment -

- Declares Dividend of $0.10 Per Share for Third Quarter -

- Updated 2023 Outlook -

Orion Office REIT Inc. (NYSE:ONL) ("Orion" or the "Company"), a fully-integrated real estate investment trust focused on the ownership, acquisition and management of single-tenant net lease mission-critical suburban office properties located across the U.S., announced today its operating results for the second quarter ended June 30, 2023.

"We continue our efforts to evolve and reposition our portfolio of high-quality properties," stated Paul McDowell, Orion's Chief Executive Officer. "We reported another solid quarter of financial performance from our high-quality portfolio, and while the pace of completing the dispositions of non-core properties and securing new leases is extended relative to our initial outlook, we continue to make progress. Most importantly, we recently completed an amendment to our credit facility that allows us to extend the maturity until 2026 and gives us the financial flexibility to execute on the Company's business plan and to maintain our low leverage balance sheet."

Second Quarter 2023 Financial and Operating Highlights

• Total Revenues of $52.0 million
• Net Loss Attributable to Common Stockholders of $(15.7) million, or $(0.28) per share
• Funds from Operations ("FFO") of $24.4 million, or $0.43 per share
• Core FFO of $26.9 million, or $0.48 per share
• EBITDA of $20.4 million, EBITDAre of $32.2 million and Adjusted EBITDA of $32.7 million
• Net Debt to Annualized Adjusted EBITDA of 3.93x

Second Quarter 2023 Financial Results

During the quarter ended June 30, 2023, the Company generated total revenues of $52.0 million, as compared to $52.8 million in the same quarter of 2022. The Company reported a net loss attributable to common stockholders of $(15.7) million, or $(0.28) per share, during the second quarter of 2023, as compared to a net loss of $(15.6) million, or $(0.27) per share, reported in the same quarter of 2022. Core FFO for the second quarter of 2023 was $26.9 million, or $0.48 per share, as compared to $28.4 million, or $0.50 per share in the same quarter of 2022. Due to the timing of an expense reimbursement that fell in the second quarter of 2023, the Company's results benefited by $0.02 per share in the quarter. This benefit is offset by $0.02 per share of expense we incurred in the first quarter of 2023, thus having no 2023 year to date or full year impact.

Leasing and Disposition Activity

During the quarter ended June 30, 2023, the Company entered into one 5.0-year lease renewal for 44,000 square feet at the Company's property in Redding, California, leased 100% to the United States Government. The Company also entered into one new 3.0-year lease for 3,000 square feet at its multi-tenant property in The Woodlands, Texas. Additionally, Orion is in various stages of negotiation and documentation for new leases and renewals at multiple properties.

Shortly after quarter end, Orion closed the sale of a 227,000 square foot vacant property in Berkeley, Missouri, for a gross sales price of approximately $9.7 million. The Company also has agreements currently in place to sell eight additional properties, representing approximately 631,000 square feet, for an aggregate sale price of $41.0 million, including the six property Walgreens campus in Deerfield, IL.

Balance Sheet and Liquidity

On June 29, 2023, the Company closed on an amendment of its credit agreement. Under the terms of the amendment, the Company used borrowings from its $425.0 million-capacity credit facility revolver to repay and retire its $175.0 million credit facility term loan which was scheduled to mature on November 12, 2023. The amendment also provides the Company with the option to extend the credit facility revolver for an additional 18 months to May 12, 2026 from the current scheduled maturity of November 12, 2024. The extension option is subject to customary conditions including the payment of an extension fee.

As of June 30, 2023, the Company has total debt of $557.3 million, comprised of $175.0 million under the Company's $425.0 million-capacity credit facility revolver, $355.0 million under the Company's securitized mortgage loan (the "CMBS Loan") and $27.3 million which represents Orion's pro rata share of indebtedness of the Unconsolidated Joint Venture.

As of June 30, 2023, Orion had $292.9 million of liquidity, comprised of $42.9 million cash on hand, including the Company's pro rata share of cash from the Unconsolidated Joint Venture, as well as $250.0 million of available capacity on Orion's $425.0 million-capacity credit facility revolver. Following quarter end, the Company deposited $28.0 million of its cash on hand into an escrow account with the credit facility lenders as additional cash collateral. These funds will, in accordance with the terms of the credit facility revolver, be used to prepay borrowings thereunder upon the scheduled expiration in November 2023 (or earlier termination) of the Company's interest rate swap agreements with respect to $175.0 million of borrowings under such revolver.

Dividend

On August 8, 2023, Orion's Board of Directors declared a quarterly cash dividend of $0.10 per share for the third quarter of 2023, payable on October 16, 2023, to stockholders of record as of September 29, 2023. The dividend was sized to permit future growth while preserving meaningful free cash flow for reinvestment into the current portfolio and for accretive investments.

Real Estate Portfolio

As of June 30, 2023, Orion's real estate portfolio consisted of 81 properties as well as a 20% ownership interest in the Arch Street Joint Venture, Orion's Unconsolidated Joint Venture with an affiliate of Arch Street Capital Partners, LLC, comprising six properties. As of June 30, 2023, the Company's portfolio occupancy rate was 86.5%, with 73.7% of annualized base rent derived from Investment-Grade Tenants, and the portfolio's weighted average remaining lease term was 3.9 years.

As of June 30, 2023, the Unconsolidated Joint Venture owned six real estate assets for total Gross Real Estate Investments of approximately $227.3 million. Orion is continuing to review a number of potential property acquisitions for its real estate portfolio.

2023 Outlook

About the Data

This data and other information described herein are as of and for the three and six months ended June 30, 2023, unless otherwise indicated. Future performance may not be consistent with past performance and is subject to change and inherent risks and uncertainties. This information should be read in conjunction with the consolidated and combined financial statements and the Management's Discussion and Analysis of Financial Condition and Results of Operations sections contained in Orion Office REIT Inc.'s (the "Company," "Orion," "us," "our" and "we") Annual Report on Form 10-K for the year ended December 31, 2022 and Quarterly Reports on Form 10-Q for the periods ended June 30, 2023 and March 31, 2023.

Definitions

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.

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 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 transaction related expenses and spin 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 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.

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 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 (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 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 items that we believe do not reflect the ongoing operating performance of our business such as transaction related expenses, spin related expenses, amortization of deferred lease incentives, amortization of deferred financing costs, equity-based compensation, amortization of premiums and discounts on debt, net and gains or losses on extinguishment of swaps and/or debt, and our pro rata 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 an equivalent 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 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.

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 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.

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 Square Feet is Rentable Square Feet leased 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 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, and less cash deposited with the credit facility lenders that will, in accordance with the terms of the credit facility revolver, be used to prepay borrowings upon expiration or termination of the Company's interest rate swap agreements. 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 Debt Leverage Ratio equals Net Debt divided by Gross Real Estate Investments.

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, transaction related expenses and spin related expenses. 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.

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.

Operating Properties refers to all properties owned and consolidated by the Company as of the applicable date.

Property Operating Expense includes reimbursable and non-reimbursable costs to operate a property, including real estate taxes, utilities, insurance, repairs, maintenance, legal, property management fees, etc.

Rentable Square Feet is leasable square feet of Operating Properties and the Company's pro rata share of leasable square feet of properties owned by the Unconsolidated Joint Venture.

Triple Net Lease ("NNN") is a lease under which the tenant agrees to pay all expenses associated with the property (e.g., real estate taxes, insurance, maintenance and repairs in accordance with the lease terms).

Unconsolidated Joint Venture means the Company's investment in the unconsolidated joint venture with an affiliate of Arch Street Capital Partners, LLC.

Unencumbered Asset Ratio equals Unencumbered Gross Real Estate Investments divided by Gross Real Estate Investments. Management believes that Unencumbered Asset Ratio is a useful supplemental measure of our overall liquidity and leverage.

Unencumbered Gross Real Estate Investments equals Gross Real Estate Investments, excluding Gross Real Estate Investments related to properties serving as collateral for the Company's CMBS Loan and the Company's pro rata share of properties owned by the Unconsolidated Joint Venture that are pledged as collateral under mortgage debt. Unencumbered Gross Real Estate Investments includes otherwise unencumbered properties which are part of the unencumbered property pool under our credit facility and therefore generally are not available to simultaneously serve as collateral under other borrowings.

Weighted Average Remaining Lease Term is the number of years remaining on each respective lease as of the applicable date, weighted based on Annualized Base Rent and includes the years remaining on each of the respective leases of the Unconsolidated Joint Venture, weighted based on the Company's pro rata share of Annualized Base Rent related to the Unconsolidated Joint Venture.

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:

• 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;
• the cost of rent concessions, tenant improvement allowances and leasing commissions;
• the potential for termination of existing leases pursuant to tenant termination rights;

• risks accompanying the management of OAP/VER Venture, LLC (the "Arch Street Joint Venture"), our unconsolidated joint venture, in which we hold a non-controlling interest;
• 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 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;
• 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;
• 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 qualification as a REIT.

Additional factors that may affect future results are contained in the Company's filings with the SEC, which are available at 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.

ORION OFFICE REIT INC.

CORE FUNDS FROM OPERATIONS PER DILUTED SHARE - 2023 GUIDANCE

(Unaudited)

The Company expects its 2023 Core FFO per diluted share to be in a range between $1.59 and $1.63. This guidance assumes:

• General & Administrative Expenses: $18.25 million to $18.75 million
• Net Debt to Adjusted EBITDA: 4.3x to 5.0x

The estimated net income per diluted share is not a projection and is provided solely to satisfy the disclosure requirements of the U.S. Securities and Exchange Commission.

The Company does not provide a reconciliation of Net Debt to Adjusted EBITDA guidance to the most directly comparable GAAP measure, due to the inherent difficulty and uncertainty in quantifying certain adjustments principally related to the Company's investment in the unconsolidated joint venture.
