Governance Snapshots

Environmental and Sustainability Snapshot

Our strategic approach to managing our ESG program is rooted in our core values-driving long-term value to all stakeholders, including the communities we serve. Our portfolio reflects our commitment to sustainability and our focus on certified buildings that prioritize the health and wellbeing of employees, tenants, residents and visitors. We create dynamic, people-centric spaces that inspire connection, creativity, productivity, health, and wellness. Our developments have a lasting impact on our communities, so we invest in the communities in which we operate through rail infrastructure, green spaces, and local financing initiatives including the Community Fund and Grow Philadelphia.

Our portfolio reflects Brandywine’s commitment to sustainability, with 15.3M square feet of green certified buildings that prioritize the health and wellbeing of occupants. Sustainability and energy efficiency are incorporated into each phase of the building’s life cycle, from construction through operation. Renewable energy, including solar, is evaluated across our portfolio and our seven solar carport systems generate 4.58 MWh of energy on an annual basis. Over the past three years, 240 energy efficiency measures were implemented, resulting in a 35% reduction in energy consumption compared to 2018.

With the challenges and changes taking place across the globe over the last few years, Brandywine conducted a survey assessment to further our understanding of the ESG aspects most impactful to our business and prioritized by stakeholders. Stakeholders who participated in the survey included employees, tenants, board members, joint venture partners and vendors. Of those respondents prioritizing ESG, the most material areas identified included cybersecurity, equal pay, environmental compliance, health & safety, and energy management. These results have informed our strategy and help to ensure that our ESG program is appropriately focused to drive value, reduce risk, and increase opportunities for success.

Office Building Operations

Our operations team continually evaluates the impact our properties have on the environment by utilizing building data to implement improvements, increase efficiencies, and create new standards to drive economies in system performance. Further, we work with tenants to implement sustainable operations in their spaces through green language in lease agreements.

The Power of Partnerships

Our Vendors and Suppliers: At Brandywine, our vendors and suppliers are more than just a part of our supply chain, they are a part of the fabric which makes our communities flourish.

Corporate Social Responsibility Snapshot

At Brandywine, we believe the value in what we do lies in the difference we can make. As such, we are committed to being good neighbors and corporate citizens in the communities in which we live and work.

Inclusive Development

Philanthropy

Since our inception, Brandywine has partnered with an array of organizations to provide donations, funding and personnel to support the causes and advocacy that are important to both our company and our employees. Highlights of this focus include:

Employee Engagement

Our employees are our greatest assets. Their commitment to excellence in their everyday encounters helps us foster a collaborative atmosphere where internal partnerships generate creativity and inspiration. As a company, Brandywine is committed to providing equal opportunity to all employees and applicants, and to fostering a culture of diversity and inclusion within our company. We recognize that a diversity of perspectives, skills and backgrounds helps to inspire creativity and new ideas and empowers us to design exceptional environments. As part of our employee training and professional development program, our employees receive the tools they need to successfully execute our mission, while simultaneously fostering career growth. In 2023, 100% of our employees received professional training, which equates to approximately 2,700 hours, and approximately 75% of our employees received ESG-specific training. Further and to emphasize the importance of continuous learning, Brandywine offers a tuition reimbursement program to our employees for qualifying educational programs. To encourage a culture of open dialogue and provide employees with the tools to align their career development with their goals, we perform annual performance reviews that give our employees an opportunity to garner formal feedback from their managers and set objectives for career growth.

Corporate Governance Snapshot

Strong corporate governance encourages accountability and transparency, as it promotes the long-term interests of shareowners, strengthens Board and management accountability, and helps build public trust in us.

Our commitment to good corporate governance has enabled us to maintain our industry-leading ISS Governance Quality Score of 1 again in 2023 - representing the highest governance rating that can be received from ISS. In addition, Brandywine continues to maintain an A Rating from MSCI ESG Research LLC.

Highlights of our corporate governance include:

Board Diversity and Refreshment

We are committed to building and maintaining a Board with diverse experiences and backgrounds and our Trustees reflect diverse perspectives, including a complementary mix of skills, experiences and backgrounds that we believe are paramount to our ability to represent the interests of our shareholders. Representation of gender, race, ethnic, geographic, cultural or other diverse perspectives expands the Board’s understanding of the needs and viewpoints of our shareholders, tenants, employees and other stakeholders. As part of our ongoing commitment to creating a balanced Board with diverse viewpoints and deep industry expertise, we regularly add new Trustees to infuse new ideas and fresh

perspectives in the boardroom. In the last five years, two new independent Trustees have been elected or appointed to the Board in replacement of two of our former Trustees. One of our two new Trustees is self-identified female, and both are self-identified as diverse based on race or ethnicity. See “Proposal 1: Election of Trustees – Trustee; Nominees“.

Information about the Meeting and Voting

You can access the virtual annual meeting at the meeting time by visiting www.virtualshareholdermeeting.com/BDN2024. By hosting the annual meeting online, we are able to communicate more effectively with our shareholders, enable increased attendance and participation, reduce costs and increase overall safety for both the Company and our shareholders. The virtual meeting has been designed to provide the same rights to participate as you would have at an in-person meeting.

If you plan to attend the annual meeting online, you will need the 16-digit control number included in your Notice of Internet Availability, on your proxy card or on the instructions that accompany your proxy materials. The annual meeting will begin promptly at 10:00 a.m. (Eastern Time). Online check-in will begin at 9:30 a.m. (Eastern Time), and you should allow ample time for the online check-in procedures.

What Am I Voting on?

Our Board of Trustees is soliciting your vote for:

If any other matter should be properly presented at the annual meeting or any postponement or adjournment of the meeting for action by the shareholders, the persons named in the proxy card will vote the proxy in accordance with his or her discretion on such matter.

What Are the Board’s Recommendations?

Our Board recommends that you vote:

		FOR the election to the Board of each of the seven nominees identified in this proxy statement, with each to serve as a Trustee for a term expiring at the 2025 annual meeting of shareholders and until his or her successor is duly elected and qualified.
		FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for calendar year 2024.
		FOR the approval of a non-binding, advisory resolution on executive compensation.

Who Is Entitled to Vote?

Holders of common shares of beneficial interest, par value $0.01 per share, or common shares, of record as of the close of business on March 26, 2024 are entitled to notice of and to vote at the annual meeting. Common shares may be voted only if the shares are represented by proxy or in person by the record holder attending the annual meeting via webcast. As of the record date, 172,270,907 common shares were issued and outstanding and entitled to vote. In addition, as of the record date, 515,595 common partnership units in Brandywine Operating Partnership, L.P. were issued and outstanding. Subject to certain conditions, these partnership units are exchangeable on a one-for-one basis for common shares. These partnership units are not entitled to vote at the annual meeting.

How Do I Vote?

Shareholders of Record

If you are a shareholder of record, there are several ways for you to vote your common shares at the annual meeting:

Beneficial Owners

If you are a shareholder whose shares are held in “street name” (i.e., in the name of a broker or other custodian), you may vote the shares at the annual meeting only if you obtain a legal proxy from the broker or other custodian giving you the right to vote the shares. Alternatively, you may have your shares voted at the meeting by following the voting instructions provided to you by your broker or custodian. Although most brokers offer voting by mail, telephone and via the Internet, availability and specific procedures will depend on their voting arrangements. If you do not provide voting instructions to your broker or other custodian, your shares are referred to as “uninstructed shares.” Under rules of the New York Stock Exchange, your broker or other custodian does not have discretion to vote uninstructed shares on non-routine matters, such as Proposals 1 or 3. Your broker or other custodian does have discretion to vote your shares on Proposal 2.

How May I Revoke or Change My Vote

You may revoke your proxy at any time before it is voted at the Meeting by any of the following methods:

What Constitutes a Quorum?

The holders of a majority of the outstanding common shares entitled to vote at the annual meeting must be present in person via attendance by live webcast or by proxy to constitute a quorum. Unless a quorum is present at the meeting, no action may be taken at the meeting except the adjournment thereof to a later time. All valid proxies returned will be included in the determination of whether a quorum is present at the meeting. The shares of a shareholder whose ballot on any or all proposals is marked as “abstain” will be treated as present for quorum purposes. “Broker non-votes,” as discussed below, will be considered as present for determining a quorum.

What Is a Broker Non-Vote?

A “broker non-vote” occurs when a broker or other nominee holding shares for a beneficial owner returns a properly-executed proxy but does not cast a vote on a particular proposal because the broker or nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

What Vote Is Required to Approve Each Proposal?

Voting Rights Generally. Each common share is entitled to one vote on each matter to be voted on at the annual meeting. Shareholders have no cumulative voting rights. The advisory vote on Proposal 3 is non-binding, as provided by law. However, our Board will review the results of the votes and, consistent with our record of shareowner engagement, will take them into account in making a determination concerning executive compensation.

Election of Trustees. Our Bylaws provide that, in an uncontested election, a nominee for Trustee is elected only if such nominee receives the affirmative vote of a majority of the total votes cast for and against such nominee. The majority voting standard would not apply in contested elections, and Trustees are elected by a plurality of the votes cast in a contested election.

The majority voting standard will apply to the election of Trustees at the annual meeting. Accordingly, a nominee for election to the Board will be elected if such nominee receives the affirmative vote of a majority of the total votes cast for

and against such nominee. Broker non-votes, if any, and abstentions will not be treated as votes cast for the election of a Trustee and will have no effect on the results of the vote, although they will be considered present for the purpose of determining the presence of a quorum. In the absence of specific direction, common shares represented by a proxy will be voted “FOR” the election of all nominees.

Our Bylaws provide that a Trustee nominated for re-election who fails to receive the required number of votes for re-election must tender his or her offer to resign to our Board of Trustees for its consideration. The Corporate Governance Committee will act on an expedited basis to determine whether it is advisable to accept the Trustee’s resignation and will submit the recommendation for prompt consideration by our Board. Our Board will act on the tendered offer of resignation within 90 days following certification of the shareholder vote and will promptly and publicly disclose its decision. The Trustee whose offer of resignation is under consideration will abstain from participating in any decision regarding his or her offer of resignation. If the offer of resignation is not accepted, the Trustee will continue to serve until the next annual meeting of shareholders and until the Trustee’s successor is duly elected and qualified or until the Trustee’s earlier resignation or removal. The Corporate Governance Committee and our Board may consider any factors they deem relevant in deciding whether to accept a Trustee’s offer of resignation.

Ratification of Appointment of Independent Registered Public Accounting Firm. Ratification of the Audit Committee’s appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for calendar year 2024 requires the affirmative vote of a majority of all of the votes cast on this Proposal. Abstentions and broker non-votes, which are not treated as votes cast, will therefore have no effect on the results of such vote. In the absence of specific direction, common shares represented by a proxy will be voted “FOR” the ratification of our independent registered public accounting firm.

Non-Binding, Advisory Vote on Executive Compensation. Approval, by non-binding vote, of our executive compensation requires the affirmative vote of a majority of all of the votes cast on this Proposal. Abstentions and broker non-votes, which are not treated as votes cast, will therefore have no effect on the results of such vote. In the absence of specific direction, common shares represented by a proxy will be voted “FOR” the approval of our executive compensation.

Who Counts the Votes?

We have engaged Broadridge Financial Solutions, Inc. (“Broadridge”) as our independent agent to receive and tabulate votes. Broadridge will separately tabulate “for” and “against” votes, abstentions and broker non-votes. We have also retained an independent inspector of elections to certify the results, report on the existence of a quorum and the validity of proxies and ballots.

What Does it Mean if I Receive More Than One Proxy Card?

Some of your shares may be registered differently or are in more than one account. You should vote each of your accounts by telephone or the Internet or mail. If you mail proxy cards, please sign, date and return each proxy card to assure that all of your shares are voted. If you hold your shares in registered form and wish to combine your shareholder accounts in the future, you should contact our transfer agent, Computershare, at (888) 985-2061; outside the U.S., (781) 575-2879. Combining accounts reduces excess printing and mailing costs, resulting in savings for us that benefit you as a shareholder.

What if I Receive Only One Set of Proxy Materials Although There Are Multiple Shareholders at My Address?

If you and other residents at your mailing address own common shares you may have received a notice that your household will receive only one annual report, proxy statement and Notice of Internet Availability of Proxy Materials. If you hold common shares in street name, you may have received this notice from your broker or other custodian and the notice may apply to each company in which you hold shares through that broker or custodian. This practice of sending only one copy of proxy materials is known as “householding.” We do this to conserve natural resources. If you did not respond to a timely notice that you did not want to participate in householding, you were deemed to have consented. You may revoke your consent to householding at any time by sending your name, the name of your brokerage firm, and your account number to Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717, or by calling telephone number (866) 540-7095. The revocation of your consent to householding will be effective 30 days following its receipt. If you did not receive an individual copy of this proxy statement, our annual report and Notice of Internet Availability of Proxy Materials, we will send a copy to you, free of charge, if you address your written request to Brandywine Realty Trust, 2929 Arch Street, Suite 1800, Philadelphia, Pennsylvania 19104, Attention: Shawn Neuman or by calling Mr. Neuman at (610) 832-7756. If you are receiving multiple copies of our annual report, proxy statement and Notice of Internet Availability of Proxy Materials, you may request householding by contacting Mr. Neuman in the same manner.

How Do I Submit a Shareholder Proposal for Next Year’s Annual Meeting?

Shareholder proposals may be submitted for inclusion in the proxy statement for our 2025 annual meeting of shareholders in accordance with rules of the Securities and Exchange Commission (“SEC”). See “Other Information – Proposals Pursuant to Rule 14a-8” later in this proxy statement. In addition, eligible shareholders are entitled to nominate and include in our proxy statement for our 2025 annual meeting Trustee nominees, subject to limitations and requirements in our Bylaws. See “Other Information – Proxy Access Trustee Nominees” later in this proxy statement. Any shareholder who wishes to propose any business at the 2025 annual meeting other than for inclusion in our proxy statement pursuant to Rule 14a-8 or nominees for election as Trustees pursuant to the proxy access provisions in our Bylaws, must provide timely notice and satisfy the other requirements in our Bylaws. See “Other Information – Other Proposals and Nominees” later in this proxy statement. Proposals should be sent via registered, certified, or express mail to Shawn Neuman, Senior Vice President, General Counsel and Secretary, Brandywine Realty Trust, 2929 Arch Street, Suite 1800, Philadelphia, Pennsylvania 19104.

Will I Receive a Copy of the Annual Report and Form 10-K?

We have furnished our 2023 Annual Report with this proxy statement. The 2023 Annual Report includes our audited financial statements, along with other financial information about us, and is not part of the proxy solicitation materials.

You may obtain a free copy of our Form 10-K, which also includes the audited financial statements of Brandywine Operating Partnership, L.P., our operating partnership subsidiary, by one of the following:

Accessing our Internet site at http://www.brandywinerealty.com and clicking on the “Investor Relations” link		Writing to our Senior Vice President, General Counsel and Secretary, Shawn Neuman, at 2929 Arch Street, Suite 1800 Philadelphia, Pennsylvania 19104		Calling Mr. Neuman at: (610) 832-7756

You may also obtain a copy of our Form 10-K and other periodic filings and current reports from the SEC’s EDGAR database at www.sec.gov.

How Can I Access the Proxy Materials Electronically?

This proxy statement and our 2023 Annual Report are available on our website at www.proxyvote.com. Instead of receiving copies of future annual reports, proxy statements, proxy cards and Notices of Internet Availability of Proxy Materials, by mail, shareholders may elect to receive an email that will provide electronic links to our proxy materials and the proxy voting site. Choosing to receive your future proxy materials or Notices of Internet Availability of Proxy Materials online will save us the cost of producing and mailing documents to you and help conserve natural resources. You may sign up for electronic delivery by visiting www.proxyvote.com.

Proposal 1: Election of Trustees

We first ask that you vote to elect to our Board each of the seven persons nominated by our Board of Trustees to serve for a term expiring at the 2025 annual meeting of shareholders and until his or her successor is duly elected and qualified. Each of the seven nominees is currently a Trustee. Each nominee has agreed to be named in this Proxy Statement and to serve if elected.

We have no reason to believe that any of the nominees will be unable or unwilling for good cause to serve if elected. However, if any nominee should become unable for any reason or unwilling for good cause to serve, proxies may be voted for another person nominated as a substitute by the Board, or the Board may reduce the number of Trustees.

Trustee Criteria, Qualifications, Experience and Tenure

We are one of the largest publicly traded, full-service, integrated real estate companies in the United States with a core focus in the Philadelphia and Austin markets. Organized as a real estate investment trust (REIT), we own, develop, lease and manage principally an urban, town center and transit-oriented portfolio comprising 158 properties and approximately 22.4 million square feet as of December 31, 2023.

Our business and affairs are managed under the direction of our Board of Trustees. Our Corporate Governance Principles contain Board membership qualifications and we strive for a mix of skills, experience and perspectives that foster a dynamic and effective Board. In selecting nominees, the Board and its Corporate Governance Committee assess the independence, character and acumen of candidates and endeavor to establish areas of core competency of the Board, including, among others, industry knowledge and experience; management, accounting and finance expertise; and demonstrated business judgment, leadership and strategic vision. Moreover, our Board values diversity of backgrounds, experiences, ethnicity, gender, perspectives and leadership in different fields when identifying nominees.

Our Board and its Corporate Governance Committee consider Trustee tenure in making Board nomination decisions and believe that it is desirable to maintain a mix of longer-tenured, experienced Trustees and newer Trustees with fresh perspectives. We also believe that longer-tenured, experienced Trustees are a significant strength of the Board, given Brandywine’s size and range of activities.

Below, we identify the key experiences, qualifications and skills our Trustee nominees bring to the Board and that the Board considers important in light of our business and industry.

The Board and its Corporate Governance Committee evaluate the Board’s own composition in the context of the diverse experiences and perspectives that the Trustees collectively bring to the boardroom.

Their backgrounds provide the Board with vital insights in areas such as:

Commercial Real Estate

Accounting and Financial

Risk Management

Mergers and Acquisition

Business Administration and Operations

Governmental and Regulatory Affairs

Marketing and Sales

Capital Deployment and Capital Markets

Executive Leadership and Talent Development

Tenant and Customer Perspective

Sustainability and Corporate Responsibility

Technology & Cybersecurity

The experiences, qualifications and skills of each Trustee that the Board considered in his or her nomination are included below the Trustees’ individual biographies on the following pages. The Board concluded that each nominee should serve as a Trustee based on the specific experience and attributes listed below each Trustees’ biography and the Board’s knowledge of each nominee, including the insight and collegiality each nominee is expected to bring to the Board’s functions and deliberations.

Annual Board Evaluation Process

The Board recognizes that a robust and constructive evaluation process is an essential part of good corporate governance and board effectiveness. The evaluation processes utilized by the Board are designed and implemented under the direction of the Corporate Governance Committee and aim to assess Board and Committee effectiveness as well as individual Trustee performance and contribution levels. The Corporate Governance Committee and full Board consider the results of the annual evaluations in connection with their review of Trustee nominees to ensure the Board continues to operate effectively.

Each year, our Trustees complete governance questionnaires and self-assessments. In addition, the Chair of the Corporate Governance Committee coordinates in-depth interviews with each of our Trustees to solicit their feedback. These questionnaires and assessments and feedback from the interviews facilitate a candid assessment of: the Board’s performance in areas such as business strategy, risk oversight, talent development and succession planning and corporate governance; the Board’s structure, composition and culture; and the mix of skills, qualifications and experiences of our Trustees.

Trustees; Nominees

The Board, upon the recommendation of the Corporate Governance Committee, has nominated each of the seven individuals identified below for election at the annual meeting and unanimously recommends that shareholders vote FOR the election of each of the nominees as Trustee. Each nominee is currently a Trustee and each nominee has agreed to serve if elected. The Trustees have no reason to believe that any of the nominees will be unable or unwilling to be a candidate for election at the time of the annual meeting. If any nominee is unable or unwilling for good cause to serve on our Board, the persons named in the proxy will use their discretion in selecting and voting for a substitute candidate or the Board may reduce the number of Trustees. Each individual elected as a Trustee at the meeting will serve for a term expiring at the next annual meeting of shareholders and until his or her successor is elected and qualified.

Our Executive Committee has authority to approve certain significant acquisitions, dispositions and other investments, subject to limitations set by the Board.

Trustee Independence; Independence Determination

No Trustee qualifies as independent unless our Board affirmatively determines that the Trustee has no material relationship with us, directly or as a partner, share owner, or officer of an organization that has a relationship with us.

Our Board has adopted standards that are set forth in our Corporate Governance Principles, which meet the listing standards of the New York Stock Exchange and assist our Board in its evaluation of each Trustee’s independence. A Trustee who has any of the following relationships or arrangements will not qualify as independent:

In its assessment of Trustee independence, our Board considers all commercial, charitable and other transactions and relationships (including tenure of Board service) that any Trustee or member of his or her immediate family may have with us, with any of our affiliates, or with any of our consultants or advisers. Our Board applies the same criteria for assessing independence for purposes of each of the Audit Committee, Compensation Committee and Corporate Governance Committee. Furthermore, in its assessment of a Trustee’s independence for service on the Compensation Committee, our Board considers all factors the Board believes specifically relevant to determining whether the Trustee has a relationship which is material to such Trustee’s ability to be independent from management in connection with his or her duties as a member of the Compensation Committee, including but not limited to any compensation payable to such Trustee. In addition, no member of the Audit Committee or Compensation Committee may accept directly or indirectly any consulting, advisory or other compensatory fee from us (other than fees for service as a Trustee and member of a Board Committee) or be an affiliate of us.

Our Board has affirmatively determined that Dr. DesRoches and Dr. Lau and Ms. Herubin and each of Messrs. Diggs, Haverstick and Pizzi is independent under the standards of the New York Stock Exchange and those set forth in our Corporate Governance Principles and that the Audit Committee, Compensation Committee and Corporate Governance Committee are comprised exclusively of independent Trustees.

Our Board did not determine Mr. Sweeney to be independent because of his position as our President and Chief Executive Officer.

Corporate Governance

Governance Compliance

Our policies and practices comply with the listing requirements of the New York Stock Exchange and the requirements of the Sarbanes-Oxley Act of 2002. Our Board and Corporate Governance Committee regularly evaluate our corporate governance policies and practices in light of changing regulatory requirements and evolving best practices.

Board Leadership Structure

Our Board believes that independent Board leadership is a critical component of our corporate governance. Mr. Sweeney is our President and Chief Executive Officer and a Trustee, and Mr. Diggs currently serves as Chair of the Board and our Lead Independent Trustee, a position he has held since 2022. As Chair and Lead Independent Trustee, Mr. Diggs presides at Board meetings and at executive sessions of non-management Trustees, oversees the agenda of Board meetings, provides guidance to our President and Chief Executive Officer as to Board views and perspectives, particularly on our strategic direction, and is available to shareholders and other parties interested in communicating with our non-management Trustees.

As President and Chief Executive Officer, Mr. Sweeney is responsible for our day-to-day operations, engaging with shareholders and external constituents, developing our future leaders and executing our strategy. The Board believes that its leadership structure, when combined with the composition of the Board, the strong leadership of our non-management Trustees, Board committees, Chair and Lead Independent Trustee, and our corporate governance structures and processes in place, (i) achieves independent oversight and evaluation of our senior management; (ii) assures effective communication between the Board and senior management on corporate strategy; and (iii) fosters effective decision-making and accountability.

The Board maintains processes that provide it with opportunities to examine and reassess the effectiveness of our Board leadership structure, including the performance of our President and Chief Executive Officer and our Chair and Lead Independent Trustee. These topics are reviewed through annual evaluations, under the oversight of our Corporate Governance Committee.

Our Board believes that our Bylaws and Corporate Governance Principles help ensure that strong and independent Trustees continue to play the central oversight role necessary to maintain our commitment to good corporate governance. Under our Articles of Amendment and Restatement of Declaration of Trust, Bylaws and Corporate Governance Principles, our Board maintains the following practices, in addition to those described above:

Talent Development; Succession Planning; Board Refreshment

Assisted by our Corporate Governance Committee, our Board assesses succession planning and talent development for key executives and company leadership. Assessments focus on succession in the event of the unexpected incapacity of our President and Chief Executive Officer as well as on talent development for key executives. Our Corporate Governance Principles provide that our President and Chief Executive Officer should at all times make available to the Board, on a confidential basis, his recommendations and evaluations of potential successors. Fundamentally, the Board’s executive succession planning is a continuous, interactive process that takes into account the Company’s operating plans and strategic goals and that seeks to attract, develop and retain a talent-rich pool of executives.

In addition, we are committed to Board succession planning and recognize the value in adding Trustees with new perspective to the Board. The Board review process involves discussion and planning for both Trustee succession and Board Committee rotation. By developing and following a long-range succession plan, the Board has an ongoing opportunity to: (i) evaluate the depth and diversity of experience of our Board; (ii) expand and replace key skills, qualifications and experiences that support our strategies; (iii) build on our record of Board diversity; and (iv) maintain a balanced mix of tenures. Two of our seven Trustee nominees will have tenures of five years or fewer upon their election at the annual meeting and our Board composition reflects our commitment to racial and gender diversity, diversity of skills and experiences and diversity of perspectives.

Trustee Orientation and Continuing Education

We provide our Trustees with comprehensive orientation and continuing education, which is overseen by our Corporate Governance Committee. Trustee orientation familiarizes new Trustees with our business and strategic plans, significant financial, accounting and risk management issues, compliance programs, policies and controls , and our principal officers. The orientation also addresses Board procedures, Board Committees and Committee charters and our Corporate Governance Principles. Our Corporate Governance Principles formalize our support for Trustee participation in continuing education sessions on business-related topics, corporate governance developments, SEC initiatives and regulatory changes, and other current topics, such as cybersecurity, pertinent to our Board and Board Committees. Our Corporate Governance Principles formalize our support for Trustee participation in continuing education sessions on business-related topics, corporate governance developments, SEC initiatives and regulatory changes, and other current topics such as cybersecurity, including issues pertinent to our Board Committees.

Prohibition on Classification of Board without Shareholder Approval Repealing Opt-out of Classified Board Provision of Maryland’s Unsolicited Takeovers Act

Our Board has adopted a resolution prohibiting us from electing to be subject to the classified board provision of Title 3, Subtitle 8 of the Maryland General Corporation Law (the “MGCL”) without a shareholder vote. Title 3, Subtitle 8 of the MGCL is commonly referred to as the Maryland Unsolicited Takeovers Act, or MUTA. As a result of our opt-out, the Board is prohibited from becoming classified under Section 3-803 of the MGCL unless a proposal to repeal that prohibition is approved by the affirmative vote of at least a majority of the votes cast on the matter by our shareholders entitled to vote generally in the election of trustees.

Shareholder Outreach and Engagement

We value the views of our shareholders and regularly solicit input from them throughout the year, including through meetings with members of management, on topics such as portfolio strategy, capital allocation, corporate liquidity, corporate governance and corporate social responsibility. Our direct shareholder engagement is in addition to our customary participation at industry and investment community conferences, investor road shows, and analyst meetings. We also respond to individual shareholders who provide feedback about our business, and we remain committed to robust engagement as a cornerstone of our corporate governance. In 2023, we met with approximately 96 institutional investors, held seven analyst meetings, conducted several investor meetings and property tours, and attended multiple investor conferences.

Executive and Trustee Share Ownership Requirements

We maintain minimum share ownership requirements for our executives and Trustees. We have summarized these requirements later in this proxy statement under “Compensation Discussion and Analysis - Additional Executive Compensation Policies and Practices - Share Ownership Requirements” for our executives and under “Proposal 1: Election of Trustees - Trustee Nominations - Trustee Compensation” for our Trustees.

Prohibition on Hedging and Pledging of Shares

Our executives and Trustees are prohibited from hedging their ownership or offsetting any decline in the market value of our shares, including by trading in publicly-traded options, puts, calls or other derivative instruments related to our shares. They are also prohibited from pledging our shares as collateral for loans.

Code of Conduct

We maintain a Code of Business Conduct and Ethics (“Code”), which is available on our website (www.brandywinerealty.com), and is applicable to our Trustees, officers and employees. The Code reflects and reinforces our commitment to integrity in our business. Any amendments to or waivers of the Code for executive officers or Trustees may only be made by the Board or by the Audit Committee (which is composed solely of independent Trustees) and will be disclosed promptly as required by law or stock exchange regulation, and, in addition, amendments to or waivers that apply to our principal executive officer, principal financial officer, principal accounting officer, controller and persons performing similar functions and that relate to any matter enumerated in Item 406(b) of Regulation S-K promulgated by the SEC will be disclosed on our website (www.brandywinerealty.com). We also notify our vendors annually of our commitment to the highest ethical standards and the restrictions in our Code on improper payments and gratuities to our personnel.

Hotline Submissions

Our Audit Committee has established procedures, set forth in our Code of Business Conduct and Ethics, for the submission of complaints about our accounting or auditing matters. There is a hotline for anonymous concerns regarding questionable accounting or auditing matters. Any financial matters reported through the hotline will be reported to the Chair of our Audit Committee. Our current hotline number is (844) 848-6595.

Availability of Committee Charters; Corporate Governance Principles; Code of Business Conduct and Ethics; Vendor Code of Conduct and Ethics; and Human Rights Policy

Our Board has adopted, and annually reviews, charters for each of the Audit, Compensation, Corporate Governance and Executive Committees. These charters and our Corporate Governance Principles, Code of Business Conduct and Ethics, Vendor Code of Conduct and Ethics and Human Rights Policy are available on our website (www.brandywinerealty.com) and we will also make available in print copies of these documents to any shareholder, without charge, upon request.

Board Oversight of Strategy and Board’s Role in Risk Oversight

One of the Board’s primary responsibilities is overseeing management’s establishment and execution of our corporate strategy and the associated risks. The full Board oversees strategy and strategic risk through robust and constructive engagement with management, taking into consideration our key priorities, national and regional trends impacting our business and disruptors to our business. The Board’s oversight of our strategy primarily occurs through extensive annual and quarterly reviews of our strategic plans. During these reviews, management provides the Board with its view of the key commercial and strategic risks and opportunities that we face; and the Board provides management with feedback on whether management has identified the key risks and opportunities and is taking appropriate responsive actions. In addition to annual and quarterly reviews, because our strategic initiatives are subject to rapidly evolving business dynamics, the Board regularly receives updates on key strategic initiatives throughout the year to ensure progress is being made against goals, understand where adjustments or refinements to strategy may be appropriate and stay current on issues impacting the business.

Our Board as a whole has responsibility for risk oversight, with reviews of certain areas being conducted by the relevant Board Committees that report on their deliberations to the Board. The oversight responsibility of the Board and its Committees is enabled by management reporting processes that are designed to provide visibility to the Board about the identification, assessment and management of critical risks and management’s risk mitigation strategies. These areas of focus include competitive, economic, operational, financial (accounting, credit, liquidity and tax), legal, regulatory, compliance, cybersecurity and data privacy, health, safety and reputational risks. The Board and its Committees oversee risks associated with their respective principal areas of focus, as summarized below.

Board Oversight of Cybersecurity and Data Privacy

Information security and privacy are of utmost importance to us to maintain the trust and confidence of our shareholders, tenants, employees and other stakeholders. Our Board recognizes the critical importance of developing, implementing, and maintaining cybersecurity measures to safeguard our information systems and protect the confidentiality, integrity, and availability of our data. We have strategically integrated cybersecurity risk management into our broader risk management framework to facilitate a company-wide awareness of cybersecurity risk management. Our management team works closely with our IT department to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. We have implemented various information security processes designed to manage material risks from cybersecurity threats to our information systems and maintain the confidentiality, integrity

and availability of our data. The Audit Committee is central to the Board’s oversight of management’s governance and management of cybersecurity risks and strategies. Although we have not experienced a data or other cybersecurity breach in the past three years, management provides updates to the Audit Committee at least quarterly, and a comprehensive briefing to the Board annually. These briefings include a review and discussion of (i) our cybersecurity, data privacy and other information technology risks and related risk management strategies, policies and procedures to protect our business systems and information, and (ii) strategies, policies and procedures to respond to potential security breach incidents, including communications plans and disaster recovery procedures.

Board Oversight of ESG

Our Board recognizes that ESG is another critical component of our risk oversight program. Oversight of ESG risks is provided by our Corporate Governance Committee, which has tasked management with continuously reviewing ESG risk exposures and presenting risk analyses to the Committee and Board regularly. These efforts are led by our Senior Vice President of Operations and Sustainability, who, together with our executive leadership, drive our ESG strategy and associated goals, risks and opportunities. ESG risks include, but are not limited to:

Disclosure Committee

We maintain an internal Disclosure Committee consisting of certain members of our executive management and senior employees. Our Disclosure Committee meets at least quarterly to bring together representatives from our core business lines and employees involved in the preparation of our financial statements so that the group may discuss any issues of which the members are aware that should be considered for disclosure in our public SEC filings. Our Disclosure Committee reports to our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer.

Trustee Nominations

In making its recommendations as to nominees for election to our Board, the Corporate Governance Committee may consider, in its sole judgment, recommendations of our President and Chief Executive Officer, other Trustees, shareholders and third parties. The Corporate Governance Committee may also retain third-party search firms to identify candidates. Shareholders desiring to recommend nominees should submit their recommendations in writing to our Board Chair, c/o Brandywine Realty Trust, 2929 Arch Street, Suite 1800, Philadelphia, Pennsylvania 19104. Recommendations from shareholders should include pertinent information as specified in our Bylaws concerning the proposed nominee’s background and experience.

Our Board’s Corporate Governance Principles set forth qualifications for Trustee nominees. Qualifications include:

The Corporate Governance Committee also considers such other factors as it deems appropriate, including the current composition of the Board. The Committee and Board believe that Board membership should reflect diversity in its broadest sense, including persons diverse in skills, perspective and background. The Committee has not adopted a formal policy for the consideration of diversity in identifying candidates for the Board. The Committee and Board also consider the bearing of each Trustee’s tenure, and the tenure of the Board as a whole, on the Board’s mix of skills and experience, independence and access to new and diverse perspectives. The Committee has not adopted different criteria for considering a candidate for nomination to the Board based on whether the party making nomination is a Trustee, shareholder or third party.

If the Committee decides, on the basis of its preliminary review of a candidate, to proceed with further consideration of the candidate, members of the Committee and the Board interview the candidate. After completing its evaluation, the Committee makes a recommendation to the full Board, which makes the final determination whether to nominate or appoint the candidate as a new Trustee. Our President and Chief Executive Officer, as a Trustee, participates in the Board’s determination.

As discussed above under “Corporate Governance - Proxy Access,” our Bylaws provide for proxy access. Proxy access enables eligible shareholders to include their nominees for election as trustees in our proxy materials for annual meetings. The proxy access provisions of our Bylaws permit up to 25 shareholders owning at least three percent of our common shares continuously for three years to nominate up to the greater of (i) two and (ii) 25 percent of the number of Trustees then serving. The complete text of our Bylaws is available on our website (www.brandywinerealty.com).

Communications with the Board

Shareholders and other parties interested in communicating directly with our lead independent Trustee and Chair of the Board, or with our non-management Trustees as a group, may do so by writing to Chair of the Board of Trustees, Brandywine Realty Trust, 2929 Arch Street, Suite 1800, Philadelphia, Pennsylvania 19104. In addition, any shareholder or interested party who wishes to communicate with our Board or any specific Trustee, may write to Board of Trustees, c/o Brandywine Realty Trust, at 2929 Arch Street, Suite 1800, Philadelphia, Pennsylvania 19104. Depending on the subject matter, management will:

At each meeting of the Board, the Chair of the Board will present a summary of all communications (if any) received since the last meeting of the Board that were not forwarded and will make those communications available to any Trustee upon request.

Meetings of Trustees and Annual Meeting of Shareholders

Our Board of Trustees held 5 meetings in 2023. In 2023, each incumbent Trustee attended at least 75% of the aggregate of the total number of meetings of the Board and meetings held by all committees on which he or she serve. In addition, our Board holds informational sessions with our President and Chief Executive Officer. During 2023, the Board held 9 informational sessions. Our non-management Trustees also hold regular meetings without management. During 2023, our non-management Trustees held 2 such meetings. It is our policy that all Trustees attend annual meetings of shareholders except where the failure to attend is due to unavoidable circumstances or conflicts. All incumbent Trustees attended our virtual annual meeting of shareholders on May 25, 2023. All of the nominees are expected to attend the 2024 annual meeting.

Trustee Compensation

The following table and footnotes provide information on the 2023 compensation of our Trustees (other than our President and Chief Executive Officer, who is not separately compensated for his service on the Board). In the paragraphs following the table and footnotes, we describe our standard compensation arrangements for service on the Board and Board Committees.

(1)  Represents the aggregate amount of all fees earned or paid in cash for services as a Trustee (including services on committees of the Board) in 2023 and, in the case of the 2023 annual retainer fee, whether paid in shares or cash. Amounts include the portion of fees that a Trustee elected to defer under our Deferred Compensation Plan, which we describe later in this proxy statement. See “Compensation Discussion and Analysis – Deferred Compensation Plan.”

(2)  Represents fully-vested common shares awarded on May 25, 2023 (with each common share valued at the closing price ($3.69) of the common shares on May 25, 2023, the date of our 2023 annual meeting of shareholders).

In 2023, our Trustees (other than our President and Chief Executive Officer) received the following compensation for their service as Trustees:

Our Trustees are also reimbursed for expenses of attending Board and Board Committee meetings. In addition, our Corporate Governance Principles encourage our Trustees to attend continuing education programs for directors and provide for reimbursement of the reasonable costs of attending such programs.

Trustees may elect to defer the receipt of all or a portion of their $45,000 annual fee and $1,500 per Board meeting fee into our Deferred Compensation Plan.

Each of our non-employee Trustees is required to own, within five years of the date of his or her initial appointment or election to the Board, a number of common shares with a value at least equal to five (5) times the annual cash retainer (currently $45,000 per year) for service on the Board based on the average of the closing price of our common shares as reported on the New York Stock Exchange for the twelve-month period ending on June 30 of the calendar year that precedes the date of computation. Each of our non-employee Trustees is in compliance with these share ownership requirements.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis (CD&A) describes our executive compensation programs, including the oversight of such programs by our Compensation Committee and the rationale and processes used to determine the compensation for the company’s named executive officers (“NEOs”) and provides a detailed description of those programs. This CD&A, which may include forward-looking statements, should be read together with the compensation tables and related disclosures that follow this section.

This discussion focuses on the compensation provided to the Company’s NEOs during 2023, who were:

		Name		Title
		Gerard H. Sweeney		President and Chief Executive Officer
		Thomas E. Wirth		Executive Vice President and Chief Financial Officer
		H. Jeffrey DeVuono		Executive Vice President, Senior Managing Director
		George D. Johnstone		Executive Vice President, Operations
		William D. Redd		Executive Vice President, Senior Managing Director

Compensation Elements

In 2023, the three key elements of our pay program continued to be base salary, annual cash incentive tied to key operational and strategic goals and long-term incentive awards linked to our common shares. This summary discusses compensation highlights from 2023.

2023 Brandywine Performance

Key 2023 Executive Compensation Actions

Annual Incentives. Consistent with prior years, the corporate scorecard used for our 2023 annual incentive plan was tied to goals relating to our operations (20%), leasing (30%) and capital investments and balance sheet strength (50%). Performance goals for the 2023 scorecard were established in the first quarter of 2023. Performance against the scorecard was achieved at 108% of the target. After review of the formulaic outcome, the Compensation Committee established 100% of target as the default payout and applied its discretion under the program to approve individual payouts to NEOs ranging from 95% to 104% of target.

Long-Term Incentives. Our long-term incentive plan is designed to align management and shareholder interests, drive long-term value creation, and attract and retain key executive talent. For 2023, one-third of an NEO’s annual long-term incentive opportunity was delivered in the form of restricted share units (RSUs) that vest in equal proportions over three years. These 2023 RSUs also have an outperformance feature attached that could increase the original award up to 225% based on Brandywine’s achievement of superior results for average funds from operations (FFO) growth and aggregate investment activity during the three-year period ending December 31, 2025, with FFO growth weighted 25% and aggregate investment activity weighted 75%. Two-thirds of an NEO’s annual long-term incentive opportunity was delivered in the form of performance share units (“PSUs”) that may be earned based on our three-year total shareholder return (TSR) versus the component members (excluding ourselves) of the FTSE NAREIT Equity Office Index.

CEO Compensation. Mr. Sweeney’s base salary remained unchanged from 2022 at $800,000. Mr. Sweeney’s target annual incentive remained 200% and his target long-term incentive opportunities as a percentage of base salary increased from 450% to 465%. As a result, Mr. Sweeney’s target total compensation increased by 2%, from $6,000,000 to $6,120,000.

2023 Say on Pay Vote. The Company values shareholder perspectives on our executive compensation program. As part of the Compensation Committee’s annual review of the program, it considers the outcome of the Company’s annual shareholder advisory vote (“say-on-pay”) on the compensation of the Company’s NEOs. Approximately 92% of the advisory votes cast in 2023 were in favor of our executive compensation program. The Compensation Committee believes that this vote is indicative of our shareholders’ support of our executive compensation program. The Compensation Committee will continue to consider shareholder feedback and the outcome of the Company’s say-on-pay votes when making future NEO compensation decisions.

Our Compensation Committee oversees and administers the Company’s executive compensation program. Our executive compensation program is designed to support our performance-based culture and the creation of value for our shareholders. The Compensation Committee is guided by the following key principles when making compensation-related decisions:

The elements of the Company’s compensation program, when considered collectively, are intended to support our executive compensation philosophy and objectives by (i) allowing us to attract and retain executive-level talent, (ii) providing an appropriate level of financial certainty through non-variable compensation, (iii) providing opportunities for above market compensation based upon the achievement of specified financial and other appropriate performance objectives, and rewarding such achievement, and (iv) balancing short-term and long-term incentives. The key elements of our executive compensation program are outlined below, together with a summary of the purposes and considerations underlying each compensation element.

II. Executive Compensation Best Practices

The Compensation Committee regularly reviews best practices in executive compensation and governance and has revised our policies and practices over time. A listing of “what we do” and “what we don’t do” is presented below:

III. Oversight of Executive Compensation

Committee Authority

Our Compensation Committee’s responsibilities include:

Compensation Consultants

Our Compensation Committee recognizes the importance of objective, independent expertise and advice in carrying out its responsibilities. The Compensation Committee continues to retain Pay Governance LLC as its consultant. Our Compensation Committee selected Pay Governance as its consultant because of its expertise and reputation. Neither we nor our Trustees or executive officers have any affiliation with Pay Governance or its executives and the engagement and direction of Pay Governance have been solely through our Compensation Committee.

During 2023, Pay Governance advised our Compensation Committee on executive compensation matters, plan design, industry trends and practices, and our pay-for-performance alignment, including realizable pay as measured relative to peers and relative to our total shareholder returns. As directed by the Committee, the consultants prepared analyses for the Committee relating to all aspects of the compensation of our executives. They advised the Committee on market practices regarding executive compensation, including annual incentive awards and long-term incentive pay, and reviewed our peer group and the market positioning of the compensation provided to our current NEOs and other senior executives. The consultants meet privately with the Committee and individual Committee members from time to time to plan for Committee meetings and discuss executive compensation matters. Pay Governance does not provide other services to us.

Our Compensation Committee received a letter from Pay Governance regarding its independence and assessed the independence of Pay Governance under New York Stock Exchange rules and concluded that Pay Governance’s work for the Committee does not raise any conflict of interest. Factors considered by the Committee include: (i) whether other services are provided to us by Pay Governance or its representatives; (ii) the amount of fees received by Pay Governance

from us as a percentage of Pay Governance’s total revenue; (iii) policies of Pay Governance designed to prevent conflicts of interest; (iv) the absence of any business or personal relationship of representatives of Pay Governance or its representatives with a member of the Committee; (v) whether Pay Governance or its advisors to the Committee own any of our securities; and (vi) whether Pay Governance or its representatives have any business or personal relationship with any of our executive officers.

Role of Executives

Our Compensation Committee seeks the views of our President and Chief Executive Officer in setting and administering our executive compensation programs. In particular, at the beginning of each year, Mr. Sweeney oversees the development of proposed corporate goals for purposes of annual incentive compensation. These goals are derived from our corporate business plan and are selected to reinforce and enhance achievement of our operating and growth objectives. The Compensation Committee reviews these goals with Mr. Sweeney, adopts revisions it deems appropriate and determines the final goals for compensation.

Following the end of each year, Mr. Sweeney reviews with the Compensation Committee, at several meetings, the achievement of corporate performance goals and the performance of each other current named executive officer and presents his evaluation of such executive officer’s performance to the Committee. Decisions about individual compensation elements and total compensation are made by the Committee, using its judgment, focusing primarily on each current named executive officer’s performance as well as our overall performance. With respect to the non-quantitative performance measures applicable to our executives, the Committee relies heavily on the views of Mr. Sweeney (other than as to himself). As President and Chief Executive Officer, Mr. Sweeney oversees the day-to-day performance of the other current named executive officers. As such, our Compensation Committee believes that he is well positioned to evaluate their performance and make recommendations as to their overall compensation.

In addition to the role played by our President and Chief Executive Officer, our other executive officers furnish such industry data and legal and financial analyses as the Committee requests from time to time.

IV. 2023 Executive Compensation

Use of Peer Group Data

Our Compensation Committee, in consultation with its compensation consultant, developed a peer group as a frame of reference for our executive compensation. Our Compensation Committee selects companies for inclusion in the peer group that primarily acquire, sell, develop, lease and manage sizeable office real estate portfolios. In selecting companies, the Committee also considers their equity and total capitalization and geographic location as well as third party considerations (for example, where members of the financial community treat a particular company as being a Company peer). Our Compensation Committee has not selected or excluded companies from the peer group on account of their compensation practices. Our Compensation Committee believes that peer group data are an indicator of compensation opportunities at companies that might recruit our executives and the data therefore help the Committee set compensation at competitive levels. Our Compensation Committee also believes that peer group data provide perspective on performance measurement practices and linkages between pay and performance. The Committee does not set specific pay targets or otherwise engage in formal “benchmarking” of compensation of our executives against executives at peer group companies. The Committee does, however, attempt to set total compensation for each current named executive near the middle of the peer group data while allowing for the possibility of greater or lesser compensation based upon our corporate and individual performance.
