**Proxy**<br>**Statement**<br>**For the 2023 Annual Meeting**<br>

The accompanying proxy card, together with this proxy statement and our 2022 Annual Report, is solicited by and on behalf of the Board of Directors (the "Board of Directors" or the "Board") of Orion Office REIT Inc., a Maryland corporation (the "Company"), for use at the 2023 Annual Meeting of Stockholders (the "Annual Meeting") and at any adjournment or postponement thereof. References in this proxy statement to "we," "us," "our" or like terms refer to the Company, and references in this proxy statement to "you" refer to the stockholders of the Company. This proxy statement and our 2022 Annual Report have either been mailed to you or been made available to you on the Internet. Mailing to our stockholders commenced on or about March 24, 2023.

ABOUT THE COMPANY

The Company is an internally-managed real estate investment trust ("REIT") engaged in the ownership, acquisition and management of a diversified portfolio of mission-critical regional and corporate headquarters office buildings in high-quality suburban markets across the U.S. and leased primarily on a single-tenant net lease basis to creditworthy tenants. As of December 31, 2022, the Company's portfolio consisted of 81 office properties totaling approximately 9.5 million total leasable square feet located across 29 states.

Upon its formation in July 2021, the Company was initially a wholly-owned subsidiary of Realty Income Corporation ("Realty Income"). Following completion of the merger transaction involving Realty Income and VEREIT, Inc. ("VEREIT") on November 1, 2021, Realty Income contributed the portion of the combined business comprising certain office real properties and related assets previously owned by subsidiaries of Realty Income, and certain office real properties and related assets previously owned by subsidiaries of VEREIT (collectively, the "Separation") to the Company and its operating partnership, Orion Office REIT LP. On November 12, 2021, following the Separation, Realty Income effected a special distribution to its stockholders (including the former holders of VEREIT common stock prior to the merger) of all of the outstanding shares of common stock of the Company (the "Distribution"). Following the Distribution, the Company became an independent publicly traded company and has been operating in a manner so as to qualify and has elected to be taxed as a REIT, commencing with its initial taxable year ending December 31, 2021.

The Company is a publicly traded Maryland corporation listed on the New York Stock Exchange under the ticker symbol "ONL." The mailing address of our principal executive offices is 2398 E. Camelback Road, Suite 1060, Phoenix, Arizona 85016.

We are an "emerging growth company" as defined in the Jumpstart Our Business Startups Act of 2012. As an emerging growth company, we provide in this proxy statement the specified scaled disclosure permitted under applicable federal securities laws. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency that such votes must be conducted.

We will cease to be an emerging growth company on the date that is the earliest of: (i) the last day of the fiscal year in which our annual gross revenues exceed $1.235 billion; (ii) the last day of our fiscal year following the fifth anniversary of the date of the Distribution; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the U.S. Securities and Exchange Commission (the "SEC").

INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

---

| |
|:---|
| **Why did I receive a notice in the mail regarding the Internet availability of the proxy materials instead of a paper copy of the proxy materials?**  |
| As permitted by rules adopted by the SEC, we are making this proxy statement and our 2022 Annual Report available to our stockholders electronically via the Internet. On or about March 24, 2023, we began mailing to many of our stockholders a Notice of Internet Availability of Proxy Materials ("Notice") containing instructions on how to access this proxy statement and our 2022 Annual Report online, as well as instructions on how to vote. If you received a Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you request a copy. Instead, the Notice instructs you on how to access and review all of the important information contained in this proxy statement and our 2022 Annual Report. The Notice also instructs you on how you may vote via the Internet. If you received a Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials included in the Notice. Our 2022 Annual Report is not part of the proxy solicitation material. |

---

---

| |
|:---|
| **Can I access the Notice, Proxy Statement and the 2022 Annual Report on the Internet?**  |
| Yes, these materials are available on our website and can be accessed at www.proxyvote.com. The information found on, or accessible through, our website is not incorporated into, and does not form a part of, this proxy statement or any other report or document we file with or furnish to the SEC. |

---

---

| |
|:---|

As of the record date, 56,639,040 shares of our common stock were issued and outstanding and entitled to vote at the Annual Meeting.  |

---

---

| |

| **How may I vote?**  |
| If you are a "registered owner" or "record holder" (*i.e*., you hold your shares in your own name as a holder of record with our transfer agent, Computershare Trust Company, N.A.) or if you are a "beneficial owner" and your bank, broker or similar organization is the holder of your shares (i.e., your shares are held in "street name"), you may attend the Annual Meeting virtually and vote your shares during the Annual Meeting. If you attend the Annual Meeting and you submit your vote during the meeting, any previous votes that you submitted by mail or authorized via the Internet or by telephone will be superseded by the vote that you cast at the Annual Meeting. To access the Annual Meeting, visit www.virtualshareholdermeeting.com/ONL2023 and enter the unique 16-digit control number included on your Notice of Internet Availability of Proxy Materials, voting instruction form, or proxy card (if you received a printed copy of the proxy materials). Further instructions for voting can be obtained by calling Broadridge Financial Solutions, Inc. at (800) 690-6903.<br>Stockholders may submit their votes by mail (if they have received a hard copy set of documents) by completing, signing, dating and returning their proxy card in the envelope enclosed with the mailing. Stockholders also have the following two options for authorizing a proxy to vote their shares: <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• via the Internet at www.proxyvote.com; or <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• by telephone to Broadridge Financial Solutions, Inc. For those who hold shares in their own name, by calling (800) 690-6903 and for shares held in "street name," by calling (800) 454-8683. <br>For those stockholders with Internet access, we encourage you to authorize a proxy to vote your shares via the Internet, a convenient means of authorizing a proxy that also provides cost savings to us. In addition, when you authorize a proxy to vote your shares via the Internet or by telephone prior to the date of the Annual Meeting, your proxy authorization is recorded immediately and there is no risk that postal delays will cause your vote by proxy to arrive late and, therefore, not be counted. For further instructions on authorizing a proxy to vote your shares, see the proxy card. <br>If your shares are held in "street name," you should instruct your bank, broker or other record holder how to vote your shares by following the voting instructions provided by such organization. If you do not give instructions to your bank, broker or record holder, such bank, broker or record holder will be entitled to vote your shares on routine items, but will not be permitted to do so on non-routine items. Your bank, broker or record holder will have discretion to vote on Proposal 2 (ratification of auditors) without any instructions from you, but such bank, broker or record holder will not have the ability to vote your uninstructed shares on Proposal 1 (election of directors) on a discretionary basis. Accordingly, if you hold your shares in "street name" and you do not instruct your bank, broker or other record holder how to vote on these proposals, such bank, broker or record holder cannot vote these shares and will report them as "broker non-votes," meaning that no votes will be cast on your behalf for Proposal 1. |

---

---

| |
|:---|
| **How will proxies be voted?**  |
| Shares represented by valid proxies will be voted at the Annual Meeting in accordance with the directions given. If you are a registered stockholder and submit a properly executed proxy but do not indicate any voting instructions, the shares will be voted "FOR" the (i) election of the director nominees named in this proxy statement and (ii) ratification of the appointment of KPMG as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2023.<br>We are not currently aware of any matters to be presented at the Annual Meeting other than those described in this proxy statement. If any other matters not described in this proxy statement are properly presented at the Annual Meeting, any proxies received by us will be voted at the discretion of the proxy holders. |

| **How can I change my vote or revoke a proxy?**  |
| You have the unconditional right to revoke your proxy at any time prior to the voting thereof by (i) submitting a later-dated proxy via the Internet, by telephone or by mail to: Broadridge Financial Solutions, Inc., 51 Mercedes Way, Edgewood, New York 11717, or (ii) by attending the Annual Meeting and voting during the meeting. No written revocation of your proxy shall be effective, however, unless and until it is received at or prior to the Annual Meeting.  |

---

---

| |
|:---|
| **What vote is required to approve each item?**  |
| A nominee for director shall be elected as a director only if such nominee receives the affirmative vote of a majority of the total votes cast for and against such nominee at the Annual Meeting at which a quorum is present. For purposes of the election of directors, a majority of the votes cast means that the number of votes cast "for" a nominee for election as a director exceeds the number of votes cast "against" that nominee. <br>The affirmative vote of a majority of the votes cast at the Annual Meeting at which a quorum is present is required for ratifying the appointment of KPMG as the Company's independent auditor for the fiscal year ending December 31, 2023. <br>Abstentions and broker non-votes, if any, will have no effect on the outcome of Proposals 1 and 2. As noted above, brokers do not have discretionary authority to vote your shares on Proposal 1. Broker non-votes are not expected to result from Proposal 2 since as a beneficial owner, your bank, broker, or other holder of record is permitted to vote your shares even if the bank, broker or record holder does not receive voting instructions from you. None of the proposals, if approved, entitle stockholders to appraisal rights under Maryland law or the Company's charter. |

---

---

| |
|:---|
| **What constitutes a "quorum"?**  |
| The presence at the Annual Meeting, in-person or represented by proxy, entitled to cast a majority of all the votes entitled to be cast at the Annual Meeting on any matter, or 28,319,521 shares, will constitute a quorum. Abstentions and broker non-votes will be counted as present for the purpose of determining whether there is a quorum.  |

| **What happens if a quorum is not present at the Annual Meeting?** |
| If a quorum is not present at the scheduled time of the Annual Meeting, the chairman of the meeting may adjourn the meeting to a later place, date or time until a quorum is present. The place, date and time of the adjourned meeting will be announced when the adjournment is taken, and no other notice will be required unless the adjournment is to a date more than 120 days after the original record date or if, after the adjournment, a new record date is fixed for the adjourned meeting. |

---

---

| |
|:---|
| **Will you incur expenses in soliciting proxies?** |
| We are soliciting the proxy on behalf of the Board of Directors, and we will pay all costs of preparing, assembling and mailing the proxy materials. We have retained Broadridge Financial Solutions, Inc., to aid in the mailing of proxy materials and tabulation and recording of votes. In addition, our directors, officers and other employees, without additional compensation, may participate in the solicitation of proxies.<br>We will request banks, brokers and other record holders to forward copies of the proxy materials to people on whose behalf they hold shares of common stock and to request authority for the exercise of proxies by the record holders on behalf of those people. In compliance with the regulations of the SEC, we will reimburse such banks, brokers and other record holders for reasonable expenses incurred by them in forwarding proxy materials to the beneficial owners of shares of our common stock.  |

---

---

| |
|:---|
| **What does it mean if I receive more than one proxy card?**  |
| Some of your shares may be registered differently or held in a different account. You should authorize a proxy to vote the shares in each of your accounts via the Internet or by telephone or by mail. If you mail proxy cards, please sign, date and return each proxy card to guarantee that all of your shares are voted. If you hold your shares in registered form and wish to combine your stockholder accounts in the future, you should call us at 602-675-0338. Combining accounts reduces excess printing and mailing costs, resulting in cost savings that benefit you as a stockholder.  |

| **What if I receive only one set of proxy materials although there are multiple stockholders at my address?**  |
| The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering to that address a single proxy statement to those stockholders. This process is referred to as "householding." The rules benefit both you and us. It reduces the volume of duplicate information received at your household and helps reduce expenses.<br>Some brokers household proxy materials, delivering a single proxy statement (including notice of annual meeting) and annual report to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Although the proxy materials may be householded, each account in a household will receive its own Notice and proxy card to vote. Once you have received notice from your broker or us that they or we will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If a single copy of the proxy statement (including notice of annual meeting) and annual report was delivered to your household and you wish to receive a separate copy of such materials, please notify us and we will promptly provide you with such copy. Additionally, if, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement (including notice of annual meeting) and annual report, or if you are receiving multiple copies of the proxy statement (including notice of annual meeting) and annual report and wish to receive only one copy, please notify your broker if your shares are held in a brokerage account, or notify us if you hold registered shares. You may notify us by calling us at 602-675-0338 or by mailing a request to us at 2398 E. Camelback Road, Suite 1060, Phoenix, Arizona 85016, Attention: Investor Relations.  |

<br>**Information**<br>**About the Board of Directors and its Committees**<br>

LEADERSHIP STRUCTURE OF THE BOARD OF DIRECTORS

The Nominating and Corporate Governance Committee evaluates the leadership structure of our Board of Directors. The positions of Non-Executive Chairman of the Board and Chief Executive Officer are separate in recognition of the differences between the two roles. Mr. Gilyard serves as our Non-Executive Chairman of the Board of Directors and presides as an independent director, while Mr. McDowell serves as our Chief Executive Officer. The Board of Directors believes this is the most appropriate structure because it enables the independent directors to participate meaningfully in the leadership of the Board while utilizing most efficiently the leadership skills of both Messrs. McDowell and Gilyard. In addition, separating the roles of Non-Executive Chairman and Chief Executive Officer allows our Non-Executive Chairman to serve as a liaison between the Board and executive management, while providing our Chief Executive Officer with the flexibility and focus needed to oversee our operations.

BOARD OVERSIGHT OF RISK MANAGEMENT

Our Board has overall responsibility for risk oversight with a focus on the more significant risks facing the Company. The Board of Directors reviews and oversees the Company's enterprise risk management ("ERM") program, which is a company-wide program designed to effectively and efficiently identify and assess management's visibility into critical company risks and to facilitate the incorporation of risk considerations into decision making, including financial information and compliance risks, economic and environmental risks, risks related to real estate and operations, and cybersecurity risks. The ERM program does this by clearly defining risks facing the Company and bringing together executive management to discuss these risks. This promotes visibility and constructive dialogue around risk at the executive management and Board levels, and facilitates appropriate risk response strategies. During the year, as part of the ERM program, management and the Board of Directors jointly discuss major risks that face our business.

While the Board oversees the overall risk management process for the Company, each of the Board's committees also assists the Board in this oversight with respect to the following risks:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Audit Committee oversees the integrity of the Company's financial statements, compliance with legal and regulatory requirements, the Company's independent registered auditors' qualifications and independence, and the performance of the Company's independent registered auditors and internal audit function;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Compensation Committee monitors the risks associated with compensation of the Company's executive officers and directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Nominating and Corporate Governance Committee oversees the risk related to our environmental, social and governance matters, including, without limitation climate change and related risks.

By assigning such responsibilities, the Board of Directors believes it can more effectively identify and address risk. Throughout the year, the Board of Directors, and each of the Board's committees will review and discuss specific risk topics in significant detail in their respective meetings. Given the importance of the Chief Executive Officer to the success of the Company and generation of stockholder value, the Board of Directors ensures that the Company is developing and nurturing a pipeline of senior talent, including one or more individuals capable of becoming the Chief Executive Officer.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE MATTERS

The Orion leadership team is committed to collaborating with tenants to implement environmental, social and governance ("ESG") initiatives across Orion's portfolio. Orion is committed to making ESG an integral component of the Company's long-term strategy for the success of Orion, as well as the communities and tenants that Orion serves.

**Environmental**

Orion is committed to following environmentally friendly practices with regard to energy and water efficiency, alternative power sources, waste management, and other initiatives that will help Orion and its tenants preserve and protect the environment.

In addition, we acknowledge the need to prepare for potential climate change-related impacts to our business and properties. We also acknowledge that we, primarily through our tenants' use of energy and water, and generation of waste, have an impact on climate change. As such, Orion intends to engage and collaborate with its tenants across its portfolio to better understand its climate-change related impacts and seek to identify areas for improvement.

In 2022, Orion instituted new policies that outline its commitment to ESG oversight and programs driving environmental stewardship. Some highlights are noted below:

*Environment, Waste, and Resource Management*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Does not generate hazardous waste

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implemented recycling programs at corporate offices

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Commitment to environmental stewardship

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• AZ and NY corporate offices located in LEED green buildings

*Climate Change*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Intend to identify areas related to climate change for potential improvements

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Board level oversight of ESG, including climate change and related risks

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implemented tenant survey to assess features of properties related to environment

**2022 Orion Office REIT Tenant Environmental Survey**

Orion owns a diversified portfolio of mission critical regional and corporate headquarters office buildings located in high quality suburban markets across the United States leased primarily on a single-tenant net-lease basis to creditworthy tenants. A significant majority of our leases are double or triple net-leases. Double and triple-net leases are leases in which the tenant occupies the property as if it is the owner. Therefore, Orion's tenants generally are solely responsible for the obligations related to the property, including paying all operating expenses associated with the property (e.g., real estate taxes, insurance, maintenance).

Because the tenant occupies the property as if it is the owner under the net-lease model, the tenant generally controls environmental practices and conditions at the property, such as waste management, and energy and water usage practices, and decides when and how to implement environmentally sustainable practices at the property. While we do not control the business operations of the tenant, as the property owner, we nevertheless recognize that the operation of commercial real estate assets can have a meaningful impact on the environment – particularly with respect to resource consumption and waste generation – and on the health of building occupants. As such, Orion intends to engage and collaborate with our tenants across our portfolio to better understand our climate-change related impacts and seek to identify areas of improvement.

Although we generally do not have direct control of our properties under the net-lease model, during 2022, to help inform our development of our ESG strategies and initiatives, Orion conducted a tenant survey to gather information regarding property specific environmental features for each property in Orion's portfolio. Key results of the 2022 survey included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Obtained information with respect to building certifications and ratings, transportation initiatives, renewable energy programs, energy efficiency initiatives, waste initiatives and water initiatives

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Overall survey response rate of 81% (excluding vacant and recently sold properties)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 81% of properties implement energy efficiency initiatives, such as LED lighting, motion detection lighting systems, energy efficient windows or energy efficient appliances

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 65% of properties implement waste initiatives, such as recycling or composting

**Board Governance Documents**

The Board maintains charters for each of its standing committees (the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee). In addition, the Board has adopted a written set of Corporate Governance Guidelines as well as a Code of Business Conduct and Ethics that applies to all of the officers, employees, consultants and directors of the Company and its subsidiaries. The Company intends to satisfy the disclosure requirement regarding any amendment to or waiver of a provision of the Code of Business Conduct and Ethics for the Company's principal executive officer, principal financial officer, principal accounting officer or persons performing similar functions, by posting such information on the Company's website. To view the charters of the Board's standing committees as well as the Corporate Governance Guidelines and the Code of Business Conduct and Ethics, please visit our website at www.onlreit.com. Each of these documents is also available, free of charge, in print to any stockholder who sends a written request to Orion Office REIT Inc., 2398 E. Camelback Road, Suite 1060, Phoenix, Arizona 85016, Attention: General Counsel and Secretary.

**Independent Directors** 

Under the listing standards of the NYSE, at least a majority of the Company's directors, and all of the members of the Company's Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee, must be independent. As part of the qualification for director independence, in addition to other specified criteria, the NYSE listing standards require our Board of Directors to affirmatively determine that the director has no material relationship with us, either directly or as a partner, stockholder or officer of an organization that has a relationship with us.

Our Board of Directors has affirmatively determined that each of the four directors - Reginald H. Gilyard, Kathleen R. Allen, Richard Lieb, and Gregory J. Whyte - has no material relationship with us (either directly or as a partner, shareholder, or officer of an organization that has a relationship with us), and that they otherwise qualify as "independent" under the NYSE's listing standards. In determining the independence of Mr. Whyte, our Board of Directors considered his role as Executive Vice President and Chief Operating Officer of Realty Income and the Company's relationship with Realty Income, which consists of transactions related to us becoming an independent public company in November 2021 pursuant to the Distribution after the Separation of the Company from Realty Income. In determining the independence of Mr. Gilyard, our Board of Directors considered his role as a non-employee director of First American Financial Corporation and CBRE Group Inc. and the Company's transactions with these companies, which consisted of ordinary course title and brokerage services.

**Service on Other Boards**

The Company's Corporate Governance Guidelines provide that our directors may not sit on more than five public company boards (including the Company's Board), or to the extent a director is a chairman or lead independent director of a public company board, then not more than four public company boards (including the Company's Board). In addition, a director appointed to the Audit Committee may not serve on more than two additional audit committees for public companies, unless the Board has made an affirmative determination that such director is able to effectively undertake the responsibilities of serving on the Audit Committee in addition to his or her positions on other such audit committees. Service on other boards and/or committees is to be consistent with the Company's conflict of interest policies and is reviewed annually.

All of our directors are currently compliant with this policy.

**Stock Ownership Guidelines for Directors and Executive Officers**

In March 2023, our Board adopted guidelines requiring each director and executive officer of the Company to hold shares of the Company's common stock (the "Stock Ownership Guidelines"). Each non-employee director of the Company is required to own common stock of the Company with a value of at least five times the individual's annual cash retainer. The Chief Executive Officer of the Company is required to own common stock of the Company with a value of at least four times his or her annual base salary. All other executive officers are required to own common stock of the Company with a value of at least two times their annual base salary. The directors and executive officers in office at the time of the adoption of the Stock Ownership Guidelines must satisfy his or her respective guideline within five years from the date the Stock Ownership Guidelines were adopted. Any future director or executive officer must satisfy his or her respective guideline within five years of the date of his or her initial appointment.

*Director Nominations.* Identifying and recommending director candidates for election to our Board is a primary responsibility of our Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee, in recommending director candidates for election to the Board, and the Board, in nominating director candidates, will consider candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments.

On an annual basis, in making a recommendation to the Board in connection with a director's nomination for election to the Board, the Nominating and Corporate Governance Committee reviews the following criteria as well as any other factor that they deem to be relevant:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The candidate's experience in corporate management, such as serving as an officer or former officer of a publicly held company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The candidate's experience as a board member of another publicly held company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The candidate's professional and academic experience relevant to the Company's industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The strength of the candidate's leadership skills;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The candidate's experience in finance and accounting and / or executive compensation practices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Time constraints including service on other public company boards and whether the candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, if applicable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The candidate's geographic background, gender, age and ethnicity.

Our Nominating and Corporate Governance Committee evaluates each nominee in the context of the Board as a whole, with the objective of assembling a group to assure that the Board, as a whole, has the necessary tools to perform its oversight function effectively in light of the Company's business and structure.

With respect to the consideration of director nominees nominated by stockholders, our Nominating and Corporate Governance Committee will consider such candidates provided that the stockholder submitting a nomination has complied with procedures set forth in the Company's Bylaws. See "Stockholder Proposals for the 2024 Annual Meeting" for additional information regarding stockholder nominations of director candidates.

Stockholders and other interested parties may communicate with the Non-Executive Chairman or with the non-employee directors, as a group, regarding any matter that is within the responsibilities of the Board.

PRE-APPROVAL POLICIES AND PROCEDURES

To help ensure the independence of the independent auditor, the Audit Committee's charter requires that the Audit Committee pre-approve all audit and non-audit services to be performed by its independent auditor prior to the engagement of such independent auditor by the Company or its subsidiaries. The Audit Committee has delegated authority to the Chairman of the Audit Committee to grant pre-approvals regarding the Company's engagement of the independent auditor for audit and non-audit services, provided that any such approvals must be presented to the full Audit Committee at a subsequent meeting and the Audit Committee must be informed of each non-audit service provided by the independent auditor. All services provided to us by KPMG have been pre-approved by the Audit Committee or the Chairman of the Audit Committee in accordance with the aforementioned delegation.

A representative of KPMG is expected to attend the Annual Meeting. The representative will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.

VOTE REQUIRED

The affirmative vote of a majority of the votes cast at the Annual Meeting is required to ratify the appointment of KPMG as our independent registered public accounting firm.

**BOARD RECOMMENDATION**<br>The Board of Directors unanimously recommends that the stockholders vote **"FOR"** the ratification of the appointment of KPMG as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2023. <br>

**Audit Committee**<br>**Report** <sup>\*</sup><br>

Management is responsible for the Company's accounting and financial reporting processes, including its internal control over financial reporting, and for preparing the Company's consolidated financial statements. KPMG, the Company's independent auditor, is responsible for performing an audit of our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB") and for expressing an opinion as to whether the Company's consolidated financial statements are fairly presented in all material respects in conformity with accounting principles generally accepted in the United States of America ("GAAP"). In this context, the responsibility of the Audit Committee is to oversee the Company's accounting and financial reporting processes and the audits of the Company's consolidated financial statements.

In the performance of its oversight function, the Audit Committee reviewed and discussed with management and KPMG the Company's audited consolidated financial statements as of and for the year ended December 31, 2022. Management and KPMG represented to the Audit Committee that the Company's audited consolidated financial statements as of and for the year ended December 31, 2022 were prepared in accordance with GAAP. The Audit Committee also discussed with KPMG the matters required to be discussed by the applicable requirements of the PCAOB and the SEC.

The Audit Committee received the written disclosures and a letter from KPMG required by the applicable requirements of the PCAOB regarding KPMG's communications with the Audit Committee concerning independence, and has discussed with KPMG its independence.

Based on the Audit Committee's review and the discussions described above, and subject to the limitations on its role and responsibilities described above and in the Audit Committee charter, the Audit Committee recommended to the Board of Directors that the audited financial statements as of and for the year ended December 31, 2022 be included in the Annual Report on Form 10-K of the Company for the year ended December 31, 2022 for filing with the SEC.

The Compensation Committee has retained Ferguson Partners Consulting L.P. ("FPC"), a nationally-known independent executive compensation and benefits consulting firm specializing in the real estate industry, to advise the Compensation Committee with respect to executive officer compensation decisions for fiscal year 2022 and executive officer opportunities, plan and design for fiscal year 2023, including a comparison of compensation levels, mix and plan structure with a group of pre-defined peer companies. The compensation framework of the Company for its executive officers is designed to foster a performance-driven, pay-for-performance culture that is intended to align our executive officers' interests with those of our stockholders while also rewarding our executive officers for superior individual achievements that promote the long-term value of the Company. The key elements of the compensation for each of our NEOs are summarized below.

NON-EQUITY COMPENSATION

**Base Salary**

The base salary payable to each of our NEOs provides a fixed component of compensation that reflects the NEO's position and responsibilities and is based on market analysis. The base salaries for our NEOs were established in the context of the nature of the respective NEO's particular position, the responsibilities associated with that position, length of service with the Company and its predecessors, experience, expertise, knowledge and qualifications, market factors, the industry in which we operate and compete, recruitment and retention factors, our Chief Executive Officer's recommendations (with the exception of his own base salary) and our overall compensation philosophy. As further described below, the respective employment arrangements of our NEOs provide for a specified or minimum base salary determined in accordance with these criteria.

In 2022, Mr. McDowell's annual base salary was $550,000, Mr. Brandon's annual base salary was $450,000 and Mr. Landriau's annual base salary was $325,000. In March 2023, the Compensation Committee approved an increase in our NEOs' annual base salary by 3% effective as of March 1, 2023.

**2022 Annual Cash Bonus Program**

In March 2022, the Compensation Committee approved an annual incentive program for the Company's 2022 fiscal year (the "2022 Bonus Program"). Under the 2022 Bonus Program, each NEO was eligible to earn an annual incentive bonus based on the applicable NEO's individual performance and the Company's achievement of performance goals relating to (1) core funds from operations per share of Company common stock ("Core FFO per share"), (2) funds available for distribution per share of Company common stock ("FAD per share"), and (3) net debt to last quarter annualized Adjusted EBITDA ("Net Debt to LQA Adjusted EBITDA"). The weighting of each component of the 2022 Bonus Program was as follows:

| Individual Performance | 33 |
| Core FFO<sup>(1)</sup> per share | 30 |
| FAD<sup>(1)</sup> per share | 13 |
| Net Debt to LQA Adjusted EBITDA<sup>(1)</sup>  | 24 |

---

(1)Core FFO, FAD, Net Debt and Adjusted EBITDA are non-GAAP financial measures. See the Company's Supplemental Information Package for 2022 Fourth Quarter and Year End for the definition of these terms.

Under the 2022 Bonus Program, 50% of each target bonus component was to be earned for performance at the threshold level, 100% of each target bonus component was to be earned for performance at the target level and 150% of each target bonus component was to be earned for performance at the maximum level (or above). Performance between threshold and target and between target and maximum performance levels was to be interpolated on a straight-line basis.

Pursuant to their respective employment agreements (as described more fully below), in 2022 each of our NEOs was eligible to earn an annual cash bonus targeted at a percentage of the NEO's base salary as follows: 100% for Mr. McDowell, 100% for Mr. Brandon and 92% for Mr. Landriau.

In March 2023, the Compensation Committee awarded the NEOs the following cash bonuses with respect to the Company's 2022 fiscal year based on the applicable NEO's performance and the Company's achievement of the performance goals set forth above.

| **Name** | **2022 Cash Bonus** |
| **Paul H. McDowell** | $731500 |
| **Gavin B. Brandon** | $598500 |
| **Gary E. Landriau** | $399000 |

---

**2023 Annual Cash Bonus Program**

In March 2023, the Compensation Committee approved an annual incentive program for the Company's 2023 fiscal year (the "2023 Bonus Program"). Under the 2023 Bonus Program, each NEO is eligible to earn an annual incentive bonus based on the applicable NEO's individual performance and the Company's achievement of performance goals relating to (1) Core FFO per share, (2) total general and administrative expenses ("G&A expenses"), and (3) Net Debt to Adjusted EBITDA. The weighting of each component of the 2023 Bonus Program is as follows:

---

| | |
|:---|:---|
| **Bonus Component** | **Weighting<br>(%)** |
| Individual Performance | 33 |
| Core FFO<sup>(1)</sup> per share | 30 |
| G&A expenses | 13 |
| Net Debt to Adjusted EBITDA | 24 |

------

(1)Beginning in 2023, the Company will be revising its definition of Core FFO. See the Company's Supplemental Information Package for 2022 Fourth Quarter and Year End for more information.

Under the 2023 Bonus Program, 50% of each target bonus component will be earned for performance at the threshold level, 100% of each target bonus component will be earned for performance at the target level and 150% of each target bonus component will be earned for performance at the maximum level (or above). Performance between threshold and target and between target and maximum performance levels will be interpolated on a straight-line basis.

Pursuant to their respective employment agreements (as described more fully below), in 2023 each of our NEOs will be eligible to earn an annual cash bonus targeted at a percentage of the NEO's base salary as follows: 100% for Mr. McDowell, 100% for Mr. Brandon and 92% for Mr. Landriau.

EQUITY COMPENSATION

We maintain the 2021 Plan pursuant to which we may grant equity incentive awards to our non-employee directors, employees (including the NEOs) and consultants of the Company and its subsidiaries. Each of our NEOs currently holds restricted stock unit awards under the 2021 Plan.

In each of March 2022 and March 2023, the Compensation Committee approved awards to the NEOs of performance-based RSUs and time-based RSUs covering shares of the Company's common stock (collectively, the "awards"), under the 2021 Plan. The following is a brief description of the material terms and conditions of the awards.

**Performance-Based RSUs** 

*General* - Pursuant to the performance-based RSUs, each NEO is eligible to vest in a number of RSUs ranging from 0% to 100% of the total number of RSUs granted (which is equal to the maximum number of RSUs that may be earned), based on the Company's total shareholder return ("TSR") measured on an absolute basis and certain operational performance metrics, in each case, during a three-year performance period, subject to the NEO's continued service with the Company. The performance period for the RSUs awarded in March 2022 commenced on January 1, 2022, and concludes on December 31, 2024 (the "2022 Performance-Based RSUs") and the performance period for the RSUs awarded in March 2023 commenced on January 1, 2023, and concludes on December 31, 2025 (the "2023 Performance-Based RSUs" and together with the 2022 Performance-Based RSUs, the "Performance-Based RSUs").

*Performance Vesting* 

The Performance-Based RSUs are eligible to vest based on the Company's (i) absolute TSR performance over the performance period ("Company TSR") (50%), (ii) achievement of acquisition related performance metrics (10%), (ii) achievement of average lease term performance metrics (20%), (iii) achievement of disposition related performance metrics (10%) and (iv) achievement of occupancy rate performance metrics (10%).

In the event that the applicable performance metric is achieved at the "threshold," "target" or "maximum" level as specified in the applicable award agreement, the performance-based RSUs eligible to vest based on achievement of such performance metrics will become vested with respect to the percentage of such performance-based RSUs set forth below:

---

| | |
|:---|:---|
| | **Performance Vesting Percentage** |
| **Below "Threshold Level"** | 0% |
| **"Threshold Level"** | 25% |
| **"Target Level"** | 50% |
| **"Maximum Level"** | 100% |

---

If the applicable performance vesting percentage falls between the levels specified as "threshold" and "target" or between the levels specified as "target" and "maximum", such performance vesting percentage will be determined using straight-line linear interpolation between such levels.

---

| | | |
|:---|:---|:---|
| 2023 Proxy Statement | **35** | Orion Office REIT Inc. |

---

------

The Company's TSR vesting percentage will be (i) reduced by 0.5%, in the case of the 2022 Performance-Based RSUs, and 1.0%, in the case of the 2023 Performance-Based RSUs, for each percentile that the Company's TSR relative to a specified group of peer companies is below the 20th percentile, and (ii) increased by 0.5%, in the case of the 2022 Performance-Based RSUs, and 1.0%, in the case of the 2023 Performance-Based RSUs, for each percentile that the Company's TSR performance relative to such peer companies is above the 80th percentile (provided that in no event will the absolute TSR vesting percentage exceed 100%), in each case, during the applicable performance period.

*Change in Control* - In the event that a change in control of the Company occurs prior to the completion of the applicable performance period, the NEO has not incurred a termination of service prior to such change in control and the awards of Performance-Based RSUs are not continued, converted, assumed or replaced by the successor or surviving entity in such change in control, then the Performance-Based RSUs will vest with respect to a number of RSUs equal to the greater of (x) the number of RSUs which would have vested based on actual performance levels as of, and assuming the completion of the applicable performance period as of the date of such change in control, and (y) the number of RSUs which would vest at target performance levels. Any such RSUs that have not fully vested as of the date on which the change in control occurs will be cancelled and forfeited by the executive.

*Certain Terminations of Service* - If an NEO's service is terminated by the Company other than for "cause," by the NEO for "good reason," or due to the NEO's death or "disability" (each as defined in the applicable award agreement), in any case, prior to the completion of the applicable performance period, the Performance-Based RSUs will vest with respect to a number of RSUs equal to the greater of (x) the number of RSUs which would have vested based on actual performance levels as of the date of such qualifying termination, and (y) the number of RSUs which would vest at target performance levels. Any such RSUs that do not become fully vested in accordance with the preceding sentence upon the administrator's determination, will be cancelled and forfeited by the NEO.

*Payment* - Any RSUs that become vested will be paid to the NEO in whole shares of the Company's common stock within 20 days after the applicable vesting date.

*Dividend Equivalents* - Each Performance-Based RSU award is granted in tandem with a corresponding dividend equivalent. Each dividend equivalent entitles the NEO to receive payments equal to the amount of the dividends paid on the share of common stock underlying the RSU to which the dividend equivalent relates. Any dividend equivalent payments that would have been made prior to the date on which the RSU becomes vested will be paid within 45 days following the date on which the RSU becomes vested. Upon the NEO's termination of service for any reason, the NEO will not be entitled to any dividend equivalent payments with respect to any RSUs that do not become vested.

The table below sets forth the target and maximum number of RSUs subject to each Performance-Based RSU Award:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **2022 Performance-Based RSUs** | **2022 Performance-Based RSUs** | **2023 Performance-Based RSUs** | **2023 Performance-Based RSUs** |

| **Gary E. Landriau** | 11255 | 22510 | 26490 | 52980 |

---

**Time-Based RSUs**

*General* - Pursuant to the time-based RSU awards, each NEO is eligible to vest in a number of RSUs that are subject to vesting based on the NEO's continued service with the Company.

*Vesting* - Each award of time-based RSUs will vest as to one-third of the RSUs on each of the first three anniversaries of the applicable vesting commencement date (March 22, 2022 for the time-based RSUs awarded in March 2022 and March 7, 2023 for the time-based RSUs awarded in March 2023), subject to the NEO's continued service through each applicable vesting date.

*Dividend Equivalents* - Each time-based RSU award is granted in tandem with a corresponding dividend equivalent. Each dividend equivalent entitles the executive to receive payments equal to the amount of the dividends paid on the share of common stock underlying the RSU to which the dividend equivalent relates. Any dividend equivalent payments that would

|:---|:---|:---|
| 2023 Proxy Statement | **36** | Orion Office REIT Inc. |

---

------

have been made prior to the date on which the RSU becomes vested will be paid within 45 days following the date on which the RSU becomes vested. The NEO will not be entitled to any dividend equivalent payments with respect to any RSUs that are forfeited prior to vesting.

*Certain Terminations of Service* - If an NEO's service is terminated by the Company or an affiliate thereof other than for "cause" or by the executive for "good reason" (each as defined in the applicable award agreement), the time-based RSUs will vest in full upon such termination. In addition, if an NEO's service is terminated due to the NEO's death or "disability" (as defined in the applicable award agreement), then a pro-rata portion of the time-based RSUs will vest based on the number of whole months during the vesting period prior to the date of such termination. Upon an NEO's termination of service for any other reason, any then-unvested time-based RSUs will automatically be cancelled and forfeited by the NEO.

The table below sets forth the number of time-based RSUs awarded to each NEO during 2022 and 2023.

We have entered into an employment agreement with Mr. Landriau pursuant to which, Mr. Landriau serves as our Executive Vice President, Chief Investment Officer. The employment agreement will continue until terminated. Pursuant to the employment agreement, Mr. Landriau received an initial annual base salary of $325,000 and is eligible to earn an annual bonus targeted at 92% of his then-current annual base salary, based upon achievement of performance goals established by the Compensation Committee in consultation with our Chief Executive Officer. The payment of any annual bonus, to the extent any annual bonus becomes payable, is contingent upon Mr. Landriau's continued employment through the applicable payment date. Pursuant to the employment agreement, Mr. Landriau is also eligible to receive annual long-term incentive equity awards during each calendar year of his employment with the Company, as may be determined by the Compensation Committee in consultation with the Chief Executive Officer. In addition, Mr. Landriau is eligible to participate in the health and welfare benefit plans and programs maintained by us for the benefit of our similarly situated executives and will accrue four weeks of vacation for each full calendar year of employment under our vacation policy.

If Mr. Landriau's employment is terminated due to his death or "disability" (as defined in his employment agreement), then in addition to accrued benefits, (i) Mr. Landriau will be entitled to any accrued but unpaid annual bonus for the year prior to the year of termination, if applicable, and (ii) any outstanding time-vesting equity awards granted to Mr. Landriau will vest on a pro rata basis. Any outstanding performance-vesting equity awards will be treated in accordance with the applicable plan and award agreement.

If Mr. Landriau's employment with us is terminated by the Company without "cause" or by Mr. Landriau for "good reason" (each as defined in his employment agreement), then subject to his execution of an effective release of claims in favor of the Company and continued compliance with certain restrictive covenants, in addition to accrued benefits, Mr. Landriau will be entitled to (i) any accrued but unpaid annual bonus for the year prior to the year of termination, if applicable, (ii) an amount equal to the sum of his annual base salary and target annual bonus for the year of termination (the "cash severance") and (iii) continued medical coverage, at the same cost to Mr. Landriau as if he were an active employee, until the earliest of: (x) one year following the date of the termination; or (y) such time as Mr. Landriau obtains new employment that offers group medical coverage. In addition, all outstanding time-vesting equity awards granted to Mr. Landriau will vest in full. Any outstanding performance-vesting equity awards will be treated in accordance with the applicable plan and award agreement. Notwithstanding the foregoing, if Mr. Landriau's employment is terminated by the Company without cause or by Mr. Landriau for good reason during the period beginning on the date of, and ending 18 months following, a change in control (as defined in the employment agreement), then, in lieu of the cash severance, Mr. Landriau will be entitled to a cash severance payment equal to two times the sum of (x) his annual base salary plus (y) an amount equal to his annual target bonus as in effect on the date of his termination, payable in a cash lump sum.

In connection with entry into the employment agreement, Mr. Landriau has executed an employee confidentiality and non-competition agreement, which includes customary confidentiality restrictions that apply indefinitely and non-compete and non-solicitation restrictions effective during employment and for 12 months thereafter.

**Incentive Compensation Clawback Policy** 

Our Board of Directors has adopted a formal clawback policy that applies to cash incentive compensation or equity-based incentive compensation. Our clawback policy is administered by the Compensation Committee and provides that the Company may require any officer of the Company to repay or forfeit certain cash and/or equity-based incentive compensation received by such officer during the three-year period preceding a "triggering event." A "triggering event" includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a decision by the Audit Committee to effect a restatement of the Company's previously published financial statements caused by material non-compliance by the Company with any financial reporting requirement under the federal securities laws due to fraud, misconduct, negligence, or lack of sufficient oversight on the part of any officer; and/or

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a decision by the Compensation Committee that one or more performance metrics used for determining previously paid cash and/or equity-based incentive compensation was incorrectly calculated and, if calculated correctly, would have resulted in a lower payment to one or more such officers.

The Compensation Committee may take into account any factors it deems reasonable in determining whether to seek recoupment of previously paid incentive compensation and how much compensation to recoup from individual officers, including any determination that such officer engaged in fraud, willful misconduct or committed grossly negligent acts or omissions which materially contributed to the events that led to the financial restatement. The amount and form of the compensation to be recouped will be determined by the Compensation Committee in its discretion.

The Company's clawback policy will be amended to conform with the mandatory clawback provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act pursuant to the recently enacted SEC requirements once NYSE listing standards implementing such requirements are finalized.

**Certain Relationships**<br>**and Related Transactions**<br>**Certain Conflict Resolution Procedures**<br>

RELATED PERSON TRANSACTION POLICY AND PROCEDURES

The Board has adopted a written Related Person Transaction Policy and Procedures for the review, approval or ratification of any related person transactions. Under this policy, the Audit Committee reviews the relevant facts and circumstances of each related party transaction, including whether the transaction is on terms comparable to those that could be obtained in arm's length dealings with an unrelated third party, whether the transaction is inconsistent with the interest of the Company and its stockholders, and the extent of the Related Person's interest in the transaction, taking into account the conflicts of interest and corporate opportunity provisions of the Company's Code of Business Conduct and Ethics. The Audit Committee either approves or disapproves the related party transaction. No director may participate in approval of a related party transaction for which he or she is a Related Person. Any related party transaction shall be consummated and shall continue only if the Audit Committee has approved or ratified such transaction in accordance with the guidelines set forth in the Related Person Transaction Policy and Procedures. For purposes of the Related Person Transaction Policy and Procedures, a "Related Person" is (i) any person who is, or at any time since the beginning of the Company's last fiscal year was, a director or executive officer or a nominee to become our director, (ii) any person who is known to be the beneficial owner of more than 5% of any class of the Company's voting securities, (iii) any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law, in each case, sharing the same household as such person.

We had no related party transactions that were subject to review under the Company's Related Person Transaction Policy and Procedures during 2022.
