HIGHLIGHTS AND PROXY SUMMARY

About Franklin Street Properties Corp.

Our company, Franklin Street Properties Corp. (sometimes referred to as the “Company,” “FSP,” “Franklin Street Properties,” “we,” “us,” or “our”) is a Maryland corporation that operates in a manner intended to qualify as a real estate investment trust (“REIT”) for federal income tax purposes. Our common stock is traded on the NYSE American under the symbol “FSP”.

We are a REIT focused on commercial real estate investments primarily in office markets and currently operate in only one segment: real estate operations. The principal revenue sources for our real estate operations include rental income from real estate leasing, property dispositions and fee income from asset/property management and development.

We invest in infill and central business district office properties in the United States sunbelt and mountain west regions as well as select opportunistic markets. We believe that the United States sunbelt and mountain west regions have macro-economic drivers that have the potential to increase occupancies and rents. We seek value-oriented investments with an eye towards long-term growth and appreciation, as well as current income.

Our investment objectives are to increase shareholder value by increasing revenue from rental, interest and fee income and net gains from sales of properties and increase the cash available for distribution in the form of dividends to our stockholders. We expect that we will continue to derive real estate revenue from owned properties.

We continue to believe that the current price of our common stock does not accurately reflect the intrinsic value of our underlying real estate assets and will continue to seek to increase shareholder value by (1) pursuing the sale of select properties where we believe that short to intermediate term valuation potential has been reached and (2) striving to lease vacant space. During 2024, our property dispositions resulted in aggregate gross proceeds of approximately $100 million and we repaid approximately $155 million of debt. We intend to use the proceeds from future dispositions primarily for the repayment of debt.

HIGHLIGHTS AND PROXY SUMMARY

Environmental, Social and Governance (ESG)

Franklin Street Properties strives to maximize stockholder value through the prudent application of sound environmental, social and governance (ESG) actions. We believe that our efforts in ESG have the potential to not only improve the health of our planet, but also to operate more efficiently, reduce property expenses, increase tenant and employee retention, and reduce company risk. Our Board of Directors (“Board”) is responsible for overseeing the ESG priorities of Franklin Street Properties, ensuring transparency and accountability.

Recent highlights of our ESG efforts are described below.

Franklin Street Properties utilizes the Environmental Protection Agency’s ENERGY STAR® program to track our progress in energy efficiency. As of year-end 2024, over 79% of our square footage, both directly-owned and asset-managed by Franklin Street Properties, had earned the ENERGY STAR® label, denoting energy performance among the top 25% of similar properties.

As of year-end 2024, approximately 68% of our square footage, both directly-owned and asset-managed by Franklin Street Properties, had been awarded some level of LEED certification. The majority of our buildings have achieved LEED Gold certification.

ADDITIONAL ESG INFORMATION

We are committed to transparent reporting of ESG information. More detailed ESG information is available on our website at http://www.fspreit.com under the heading “ESG”. The information on our website is not a part of this Proxy Statement and is not incorporated into any of our filings made with the Securities and Exchange Commission (the “SEC”).

HIGHLIGHTS AND PROXY SUMMARY

Board Nominees (Proposal 1)

On November 27, 2024, following shareholder engagement regarding the appointment of a shareholder-recommended candidate to our Board, the size of our Board was increased from seven to eight members and Bruce J. Schanzer was appointed to our Board. Kenneth A. Hoxsie and Brian N. Hansen, members of our Board, have notified us that they will not stand for re-election at the Annual Meeting. Consequently, the terms of Mr. Hoxsie and Mr. Hansen as directors will expire at the Annual Meeting, and the size of our Board will decrease to six members immediately after the conclusion of the Annual Meeting. Our Nominating and Corporate Governance Committee has recommended, and our Board has determined, to nominate all other current members of our Board for re-election at the Annual Meeting. We are asking our stockholders to vote “FOR” our nominees, George J. Carter, Georgia Murray, John N. Burke, Dennis J. McGillicuddy, Bruce J. Schanzer and Milton P. Wilkins, Jr., as directors for a one-year term expiring at our 2026 Annual Meeting of Stockholders.

The following table provides summary information about each of the director nominees, who have a diverse and balanced skill set including extensive real estate, financial, investment, corporate, securities, management, and investor relations experience. We encourage you to review the qualifications, skills and experience of our directors on pages 17-22.

Also, on or about April 3, 2025, we will begin mailing printed copies of these proxy materials to stockholders who have requested printed copies. If you receive the 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 the documents online to review all of the important information contained in this Proxy Statement and our 2024 Annual Report to Stockholders. The Notice also instructs you on how you may vote via the Internet.

| FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT | 9

QUESTIONS AND ANSWERS

3. What are the Voting Recommendations of the Board?

Your Board recommends that you vote your shares as follows:

“FOR” each director nominee and “FOR” Proposal 2 and Proposal 3.

Proposal 1 is for the election of six directors. It is a binding vote and, if approved, the nominees will be elected to serve a one-year term on our Board.

Proposal 2 is for the ratification of the appointment of our independent registered public accounting firm. It is a non-binding vote and is not required, but our Audit Committee will carefully consider the outcome of this vote in determining its next selection of our independent registered public accounting firm.

Proposal 3 is a vote on our executive compensation and, under the Securities Exchange Act of 1934 (as amended, the “Exchange Act”) and related SEC regulations, it is an advisory, or non-binding, vote. Our Board will carefully consider the outcome of this vote.

4. Who can Vote at the Annual Meeting?

Our Board has fixed the close of business on March 4, 2025 as the record date (the “Record Date”) for the Annual Meeting. If you were a stockholder of record on the Record Date, you are entitled to vote (online during the Annual Meeting or by proxy) all of the shares that you held on that date at the Annual Meeting and at any postponement, or adjournment thereof.

Franklin Street Properties has only one class of Common Stock outstanding. Each share of Common Stock outstanding as of the close of business on the Record Date is entitled to one vote at the Annual Meeting. As of the Record Date, Franklin Street Properties had 103,566,715 shares of Common Stock outstanding and entitled to vote at the Annual Meeting.

5. Can I Vote if my Shares are Held in “street name”?

All shares of Common Stock owned by you as of the Record Date may be voted by you. These shares include those (1) held directly in your name as a stockholder of record and (2) held for you as the beneficial owner through a broker, financial institution or other nominee.

Most of the stockholders of Franklin Street Properties hold their shares in “street name” through a broker, financial institution or other nominee rather than directly in their own name. As summarized below, there are some distinctions between being a “record” holder and being a “beneficial” holder of our shares.

6. What does it Mean to be a Stockholder of Record?

If, on the Record Date, your shares of Common Stock are registered directly in your name with Franklin Street Properties’ transfer agent, Equiniti Trust Company, LLC (formerly known as American Stock Transfer & Trust Company), you are considered the stockholder of record of those shares, and the Notice or set of printed proxy materials, as applicable, is being sent directly to you. As the stockholder of record, you have the right to grant your voting proxy directly to the persons named in the proxy card or to vote online during the Annual Meeting. If you request a paper copy of the materials as described in the Notice, a proxy card will be sent to you with those materials.

7. What does it Mean to Beneficially Own Shares in Street Name?

If, on the Record Date, your shares of Common Stock are held in a brokerage account by a broker, financial institution or other nominee, you are considered the beneficial owner of shares held on your behalf in “street name”, and the Notice or set of printed proxy materials, as applicable, is being forwarded to you by your broker, financial institution or other nominee who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, financial institution or other nominee on how to vote the shares held in your account. You should receive information from your broker, financial institution or other nominee on how you can direct the voting of your shares. If you

QUESTIONS AND ANSWERS

request a paper copy of the proxy materials as indicated in the Notice, your broker, financial institution or other nominee will provide a voting instruction card for you to use to direct the voting of your shares. As a beneficial owner, you may virtually attend the Annual Meeting and vote your shares online while attending the virtual Annual Meeting by following the instructions set forth below in “How do I Vote?”.

8. Why are we Holding a Virtual Annual Meeting and How Do I Attend?

In order to enhance participation, this year’s Annual Meeting will be conducted as a virtual meeting solely via live audio webcast on the internet. You are entitled to participate in the virtual Annual Meeting only if you were a stockholder of Franklin Street Properties as of the close of business on the Record Date for the Annual Meeting. You will be able to attend the Annual Meeting online and vote and submit questions online during the meeting by visiting www.virtualshareholdermeeting.com/FSP2025. You will not be able to attend the Annual Meeting in person. The audio webcast will start at 11:00 a.m. Eastern Time on May 15, 2025. You will need the 16-digit control number included on your Notice, proxy card or voting instruction form in order to be able to attend the Annual Meeting online. Online access to the audio webcast will open at 10:45 a.m. Eastern Time to allow time for you to log in and test your device’s audio system. We encourage you to access the meeting prior to the start time. If you encounter any difficulties accessing the virtual Annual Meeting during check-in or the meeting, please call the technical support number that will be posted on the virtual meeting log-in page. We will have technicians available to assist you.

We have designed our virtual Annual Meeting format to enhance, rather than to constrain, stockholder access, participation and communication. For example, the virtual Annual Meeting format allows stockholders, regardless of location, to communicate with us during the Annual Meeting so they can ask questions of our Board or management, as time permits. In addition, a representative of our auditor, Ernst & Young LLP, will also attend the virtual Annual Meeting and will be available to answer appropriate questions at that time. We believe that the virtual Annual Meeting will provide stockholders with at least the same rights and opportunities to participate as they would have at an in-person meeting.

9. How do I Vote?

Voting at the virtual Annual Meeting. If you attend the virtual Annual Meeting, you may vote your shares of Common Stock online at the time of the Annual Meeting by visiting www.virtualshareholdermeeting.com/FSP2025. To participate and vote during the virtual Annual Meeting, stockholders of record will need the 16-digit control number included on your Notice or on your proxy card. Beneficial stockholders who do not have a control number may gain access to and vote at the virtual Annual Meeting by logging into their broker, brokerage firm, bank or other nominee’s website and selecting the stockholder communications mailbox to access the virtual Annual Meeting; instructions should also be provided on the voting instruction card provided by your broker, bank, or other nominee. Even if you plan to attend the virtual Annual Meeting, we recommend that you vote your shares in advance, so that your vote will be counted if you later decide not to attend the virtual Annual Meeting.

If your shares of Common Stock are held in “street name”, you will receive instructions from your broker, financial institution or other nominee that you must follow in order to have your shares of Common Stock voted as you direct. Those instructions may have accompanied these printed materials.

10. What are the Quorum and Voting Requirements for the Proposals?

The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares of Common Stock entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares present virtually during the Annual Meeting will be considered shares of Common Stock represented in person at the meeting. As of the Record Date, there were 103,566,715 shares of Common Stock outstanding and entitled to vote at the Annual Meeting. Abstentions and broker non-votes (described below), if any, will be considered present for the purpose of determining the presence of a quorum.

Broker non-votes occur when brokers, financial institutions or other nominees do not receive voting instructions from their customers on how to vote the customers’ shares on a proposal and the broker, financial institution or other nominee does not have discretionary voting authority or chooses not to exercise it with respect to a proposal.

Proposal 1 – Election of Directors. The affirmative vote of a majority of the total votes cast for and against each nominee for director is required to approve the election of each nominee for director in Proposal 1. Votes may be cast FOR or AGAINST with respect to each nominee. Shares held in “street name” by brokers, financial institutions or other nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 1 will not be counted as votes FOR or AGAINST from any nominee and will be treated as broker non-votes. Those broker non-votes, if any, will not be counted as votes cast and will have no effect on the result of the vote. Abstentions will not be counted as votes cast and will have no effect on the result of the vote.

Proposal 2 – Ratification of the Appointment of Independent Registered Public Accounting Firm. A majority of the votes cast at the Annual Meeting is required to ratify the appointment of Ernst & Young LLP. You may vote FOR or AGAINST, or abstain from ratifying the appointment of Ernst & Young LLP. Abstentions will not be counted as votes cast and will have no effect on the result of the vote. If your shares are held by your broker, financial institution or other nominee in “street name” and you do not provide voting instructions with respect to your shares, we expect that your broker, financial institution or other nominee may vote your shares on Proposal 2 in its discretion.

Proposal 3 – Advisory Vote on Executive Compensation. A majority of the votes cast at the Annual Meeting is required for approval of the advisory vote on executive compensation. You may vote FOR or AGAINST Proposal 3 or you may abstain from voting on Proposal 3. Shares held in “street name” by brokers, financial institutions or other nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 3 will not be counted as votes FOR or AGAINST Proposal 3 and will be treated as broker non-votes. Abstentions and broker non-votes, if any, will not be counted as votes cast and will have no effect on the result of the voting on Proposal 3.

11. What if I Change my Mind after I have Voted?

You may revoke your proxy and change your vote at any time before it is voted at the Annual Meeting by (1) sending a written notice of revocation to our Secretary at the Company’s address set forth in this Proxy Statement that is received prior to the time at which your proxy is voted at the Annual Meeting and submitting a new written proxy bearing a date later than the date of the proxy being revoked; (2) submitting a new proxy by voting again via the Internet or by telephone prior to 11:59 p.m. Eastern Time on Wednesday, May 14, 2025; or (3) attending the virtual Annual Meeting online and voting electronically during the virtual Annual Meeting. Attendance at the virtual Annual Meeting online will not, in itself, constitute revocation of a previously granted proxy.

12 | FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT |

QUESTIONS AND ANSWERS

If you hold your shares in “street name”, then you may submit new voting instructions by contacting your broker, financial institution or nominee. You may also vote online while virtually attending the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions.

12. How will my Shares be Voted if I do not Return my Proxy or do not Provide Specific Instructions in the Proxy Card that I Submit?

If you are a stockholder of record, your shares will not be voted if you do not vote over the Internet, by telephone, by returning your proxy or by voting electronically during the virtual Annual Meeting. If you submit a proxy card without giving specific voting instructions on one or more proposals listed in the notice for the Annual Meeting, your shares will be voted as recommended by our Board on such proposals, and as the proxy holders may determine in their discretion how to vote with respect to any other proposals properly presented for a vote at the Annual Meeting.

If you hold shares in “street name” and you do not give instructions as to how to vote your shares, your broker, financial institution or other nominee may have authority to vote your shares on certain matters. Of the matters to be voted on at the Annual Meeting, we expect the only proposal on which your broker, financial institution or other nominee will have discretionary voting authority is the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025 (Proposal 2).

13. Where do I Find the Voting Results of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We will also publish preliminary or, if available, final voting results within four business days of the Annual Meeting in a Current Report on Form 8-K to be filed with the SEC. If necessary, we will publish final voting results within four business days after the final voting results are known in an amendment to Current Report on Form 8-K to be filed with the SEC. Copies of the Current Report on Form 8-K and any amendments thereto to be filed with the SEC will be available on our website at: http://www.fspreit.com and on the SEC’s website at http://www.sec.gov.

14. Will other Matters be Voted on at the Annual Meeting?

We are not currently aware of any other matters to be presented at the Annual Meeting other than those described in this Proxy Statement. If any other matters not described in the Proxy Statement are properly presented at the Annual Meeting, any proxies received by us will be voted in the discretion of the proxy holders.

15. How do I Submit a Question at the Virtual Annual Meeting?

During the Annual Meeting, you can view our agenda and rules of conduct and procedures and submit questions at www.virtualshareholdermeeting.com/FSP2025. Stockholders must have their 16-digit control number to submit questions. During the Annual Meeting, we intend to answer all questions submitted that are pertinent to the Company and the items being voted on by stockholders, as time permits and in accordance with our rules of conduct and procedures. If we are unable to respond to a stockholder’s properly submitted question due to time constraints, we will either post the response on the investor relations section of our website following the Annual Meeting, or respond directly to that stockholder using the contact information provided. The business of the Annual Meeting will be taken up as set forth in the agenda. When an item on the agenda is before the Annual Meeting for consideration, appropriate and relevant questions will be addressed at that time. We will seek to limit the discussion of each agenda item to no more than 10 minutes. If a stockholder has a question that is not related to an agenda item, the question will be deferred to the question and answer session after the formal portion of the Annual Meeting. We reserve the right to end the question and answer session of the Annual Meeting after a reasonable amount of time. At the appropriate time, we will read out the applicable questions and will provide responses as necessary. Substantially similar questions will be answered only once. To promote fairness and due to time constraints, we will respond to no more than two questions from any single stockholder.

QUESTIONS AND ANSWERS

Communications and Stockholder Proposals

16. How can I Communicate with the Company’s Directors?

Our Board will give appropriate attention to written communications that are submitted by stockholders and will respond if and as appropriate. The Secretary of Franklin Street Properties is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the other directors as he or she considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the Secretary considers to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we may receive repetitive or duplicative communications.

Stockholders who wish to send communications on any topic to our Board should address such communications to Board of Directors, Franklin Street Properties Corp., 401 Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, Attn: Scott H. Carter, Secretary.

17. How do I Submit a Proposal for Action at the 2026 Annual Meeting?

In accordance with Rule 14a-8 of the Exchange Act, proposals of stockholders intended to be included in our proxy statement and form of proxy for the 2026 Annual Meeting of Stockholders must be received by Franklin Street Properties at its principal office not later than December 4, 2025. In addition, according to our current bylaws, any stockholder proposal intended to be presented at an annual meeting, including nominations for election to the Board, but not considered for inclusion in our proxy statement relating to such meeting, must be received at Franklin Street Properties’ principal office not earlier than the 150th day nor later than 5:00 p.m., Eastern Time, on the 120th day prior to the first anniversary of the mailing date of the preceding year’s proxy materials. For the 2026 Annual Meeting of Stockholders, that means that a stockholder must deliver proper notice of a proposed nominee or action that is proposed to be presented at the 2026 Annual Meeting of Stockholders but not be included in the proxy statement for such meeting to the Secretary of Franklin Street Properties between November 4, 2025 and December 4, 2025. In addition to the timing of the delivery of the notice, our bylaws include specific information that must be provided (including the information required by Rule 14a-19 under the Exchange Act) and procedures that must be followed to submit a proposal.

PROPOSAL ONE — ELECTION OF DIRECTORS

All members of our Board are elected annually by our shareholders. Our Board currently consists of eight directors.

CORPORATE GOVERNANCE

CORPORATE GOVERNANCE

We operate within a comprehensive corporate governance structure that includes the highest standards of professional and personal conduct. Our Corporate Governance Guidelines, our Code of Business Conduct and Ethics, the charters of our Audit, Compensation, and Nominating and Corporate Governance Committees, and other corporate governance information, are available on our website at http://www.fspreit.com under the heading “Investor Relations” and then under the subheading “Governance Documents” under “Corporate Information.” The information on our website is not a part of this Proxy Statement and is not incorporated into any of our filings made with the SEC.

Introduction

Our Common Stock trades on NYSE American under the symbol “FSP”. We began trading on the American Stock Exchange in June 2005. The exchange’s name was changed to NYSE Amex after it was acquired by NYSE Euronext on October 1, 2008, was later known as NYSE MKT and is now NYSE American.

Board of Directors

Franklin Street Properties is currently managed by an eight-member Board. The size of our Board will decrease to six members immediately after conclusion of the Annual Meeting. All directors are elected to serve one-year terms (in all cases subject to the election and qualification of their successors or to their earlier death, resignation or removal).

Director Independence

Under the NYSE American corporate governance standards, set out in the NYSE American LLC Company Guide (the “NYSE American Rules”), at least a majority of the Board must be “independent directors” as defined in Section 803A of the NYSE American Rules. According to Section 803A, “independent director” means a person other than an executive officer or employee of Franklin Street Properties. In addition, to qualify as an “independent director,” the Board of Directors must affirmatively determine that the director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Section 803A of the NYSE American Rules also includes the following non-exclusive list of persons who shall not be considered independent:

| a. | a director who is, or during the past three years was, employed by us, other than prior employment as an interim executive officer (provided the interim employment did not last longer than one year);

| b. | a director who accepted or has an immediate family member who accepted any compensation from us in excess of $120,000 during any period of twelve consecutive months within the three years preceding the determination of independence, other than the following:

| i. | compensation for Board or Board committee service,

| ii. | compensation paid to an immediate family member who is an employee (other than an executive officer) of Franklin Street Properties,

| iii. | compensation received for former service as an interim executive officer (provided the interim employment did not last longer than one year), or

| iv. | benefits under a tax-qualified retirement plan, or non-discretionary compensation;

| c. | a director who is an immediate family member of an individual who is, or at any time during the past three years was, employed by us as an executive officer;

| FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT | 23

CORPORATE GOVERNANCE

| d. | a director who is, or has an immediate family member who is, a partner in, or a controlling shareholder or an executive officer of, any organization to which we made, or from which we received, payments (other than those arising solely from investments in our securities or payments under non-discretionary charitable contribution matching programs) that exceed 5% of the organization’s consolidated gross revenues for that year, or $200,000, whichever is more, in any of the most recent three fiscal years;

| e. | a director who is, or has an immediate family member who is, employed as an executive officer of another entity where at any time during the most recent three fiscal years any of our executive officers serve on the compensation committee of such other entity; or

| f. | a director who is, or has an immediate family member who is, a current partner of our outside auditor, or was a partner or employee of our outside auditor who worked on our audit at any time during any of the past three years.

For purposes of Section 803A of the NYSE American Rules, “immediate family member” includes a person’s spouse, parents, children, siblings, mother-in-law, father-in-law, brother-in-law, sister-in-law, son-in-law, daughter-in-law, and anyone who resides in such person’s home (other than domestic employees).

Because Ms. Murray and Messrs. Burke, McGillicuddy, Schanzer and Wilkins do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, our Board has determined that they are “independent directors” for purposes of the NYSE American Rules.

Board Meetings, Annual Meeting of Stockholders, and Attendance

During 2024, each director attended more than 75% of the meetings of the Board and of the committees on which he or she served. The Board held seven meetings in 2024.

Each of our directors then serving on the Board attended the 2024 Annual Meeting of Stockholders.

Current Board Leadership Structure

At the present time, our Board has chosen to combine the Chairman and Chief Executive Officer positions. Our Board believes that George J. Carter is best suited to serve as both Chairman and Chief Executive Officer because he is most familiar with Franklin Street Properties’ business and industry and is most capable of effectively identifying strategic priorities and leading the discussion and execution of strategy. Mr. Carter has served as Chief Executive Officer and Chairman since he founded Franklin Street Properties, originally Franklin Street Partners Limited Partnership. Our Board believes that independent directors and management have different perspectives and roles in our strategy development. Our independent directors bring experience, oversight and expertise from outside Franklin Street Properties and its industry, while the Chief Executive Officer brings company-specific experience and expertise. Our Board believes that, at the present time, the combined role of Chairman and Chief Executive Officer is in the best interests of Franklin Street Properties and our stockholders and is consistent with good corporate governance. The combined role promotes strategy development and execution and facilitates information flow between management and the Board, which are essential to effective governance. Our Board encourages strong communication among all of its independent directors and the Chairman and Chief Executive Officer, and our Board believes that it has been able to, and will continue to, effectively provide independent oversight of our business and affairs, including the risks we face, through the role of our Lead Independent Director, the independent committees of our Board, the overall composition of our Board and contributions from all of our independent directors and other corporate governance policies in effect.

24 | FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT |

CORPORATE GOVERNANCE

Lead Independent Director

Since February 7, 2014, Georgia Murray has served as Lead Independent Director. The Lead Independent Director’s duties include: coordinating the activities of our independent directors, coordinating the agenda for and chairing sessions of our independent directors, serving as the principal liaison for consultation and communication between our independent directors and our stockholders, facilitating communications between our independent directors, the other members of our Board and our management, and performing such other duties as our Board may from time to time delegate. In performing the duties described above, the Lead Independent Director is expected to consult with the chairs of the appropriate Board committees and solicit their participation in order to avoid diluting the authority or responsibility of such committee chairs.

The Board’s Role in Succession Planning

The Board expects management to have an ongoing program for effective senior leadership development and succession. As reflected in our Corporate Governance Guidelines, the Board works on a periodic basis with the Chief Executive Officer to review, maintain and revise, if necessary, the Company’s succession plan upon the conclusion of the Chief Executive Officer’s service as our Chief Executive Officer for any reason. The Chief Executive Officer reports periodically to the Board on succession planning for the Chief Executive Officer and senior management positions, which report includes a discussion of assessments, leadership development plans and other relevant factors.

The Board’s Role in Risk Oversight

Our Board has the primary responsibility for overseeing the Company’s risk management processes. A portion of this responsibility has been delegated by the Board to the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee, each with respect to the assessment of the risks and risk management in their respective areas of oversight. In general, our Board oversees risk management activities relating to business strategy, acquisitions, dispositions, capital allocation, organizational structure and certain operational risks. Our Audit Committee oversees risk management activities related to financial controls, legal and compliance risks and potential cyber-attacks and intrusions; our Compensation Committee oversees risk management activities relating to our compensation policies and practices; and our Nominating and Corporate Governance Committee oversees risks relating to our nominating and corporate governance policies and practices. Each committee reports to the full Board on a regular basis, including reports with respect to the committee’s risk oversight activities as appropriate. These committees and the full Board focus on the most significant risks facing the Company and the Company’s general risk management strategy, and also ensure that risks undertaken by the Company are consistent with the Board’s appetite for risk. While the Board oversees the Company’s risk management, the Company’s management is responsible for day-to-day risk management processes. We believe this division of responsibilities is the most effective approach for addressing the risks facing the Company and that the leadership structure of our Board supports this approach. The Board and each of our committees regularly discusses with management our major risk exposures, their potential financial impact on Franklin Street Properties, and the steps we take to manage them. The Board and each of our committees exercise their oversight responsibilities in a variety of ways, but in all cases our directors are informed by regular reports from the Company’s management that are intended to identify key risks and our strategies to mitigate them.

Executive Sessions

Each director has the right to call an executive session without management participation after each regularly scheduled meeting of the entire Board and at such other times that the directors deem such a meeting to be appropriate. Similarly, each independent director has the right to call an executive session with only independent directors present after each regularly scheduled meeting of the entire Board and at such other times that an independent director deems appropriate. At a minimum, the independent directors meet in executive session at least annually without the presence of non-independent directors and management.

Our Board has the following three standing committees: (1) Audit, (2) Compensation and (3) Nominating and Corporate Governance. The membership and the function of each of these committees are described below.

The Audit Committee, among other functions, (1) has the sole authority to appoint, evaluate, terminate and determine the compensation of our independent registered public accounting firm, (2) reviews with our independent registered public accounting firm the scope and results of the audit engagement, (3) approves professional services provided by our independent registered public accounting firm, (4) reviews the independence of our independent registered public accounting firm, (5) reviews and approves our policies and procedures for reviewing and approving or ratifying related person transactions, (6) reviews and approves our entry into swaps and (7) periodically reviews with management our cybersecurity and other information technology risks, controls and procedures, including our plans to mitigate cybersecurity risks and respond to data breaches. Our Board has determined that each member of the Audit Committee is “independent” as that term is defined under the NYSE American Rules, including the independence requirements contemplated by Rule 10A-3 under the Exchange Act. Our Board determined that Mr. Burke qualifies as an “audit committee financial expert” as that term is defined in the rules of the SEC. The Audit Committee Report is included later in this Proxy Statement. The Audit Committee met five times during 2024.

Compensation Committee. Our Board has established a Compensation Committee which operates pursuant to a charter that was approved by our Board and that is reviewed and reassessed at least annually. Our Board has determined that each member of the Compensation Committee has been determined to be “independent” under the NYSE American Rules, including the independence requirements under Rule 10C-1 under the Exchange Act. The Compensation Committee’s responsibilities include, among other duties, the responsibility to (1) review and approve the corporate goals and objectives relevant to the compensation of the Chief Executive Officer, (2) evaluate the performance of the Chief Executive Officer in light of such goals and objectives and either determine and approve or recommend to our Board for approval the compensation of the Chief Executive Officer based on such evaluation, (3) oversee the evaluation of our other executive officers, (4) review and approve the compensation of our other executive officers, (5) review and make recommendations to our Board with respect to incentive compensation and equity-based plans, (6) review and make recommendations to our Board with respect to the compensation of our non-employee directors, (7) approve, or recommend for approval by our Board, the implementation or revision of any compensatory recovery or “clawback” policies, and oversee the administration of such policies and (8) perform other functions or duties deemed appropriate by the Board.

The Compensation Committee is authorized to retain and terminate any compensation consultant to assist in the evaluation of executive officer compensation and to approve the consultant’s fees and other retention terms and to pay the compensation without further action by the Board. The Compensation Committee also has authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors as the Compensation Committee deems necessary or appropriate, and is responsible for assessing the independence of such consultants and advisors, overseeing the work of such consultants and advisors and authorizing the payment of such consultants and advisors. The Compensation Committee makes all compensation decisions relating to compensation of our executive officers other than the Chief Executive Officer and makes a recommendation regarding the compensation of our Chief Executive Officer to the Board. The Chief Executive Officer is not permitted to be present during any deliberations or voting relating to the Chief Executive Officer’s compensation. The Compensation Committee takes into consideration recommendations made by the Chief Executive Officer with respect to compensation decisions relating to executive officers other than the Chief Executive Officer. The Compensation Committee Report is included later in this Proxy Statement.

CORPORATE GOVERNANCE

The Compensation Committee met two times during 2024.

Nominating and Corporate Governance Committee. Our Board has established a Nominating and Corporate Governance Committee which operates pursuant to a charter approved by our Board and is reviewed and reassessed by the Nominating and Corporate Governance Committee at least annually. The Nominating and Corporate Governance Committee is responsible for identifying and recommending individuals to become members of our Board, periodically reviewing our Corporate Governance Guidelines and other corporate governance documents and recommending any changes, as well as ensuring that we are in compliance with all corporate governance and listing standards of the NYSE American. The Nominating and Corporate Governance Committee is also responsible for overseeing the annual evaluation of the Board. The Nominating and Corporate Governance Committee is authorized to retain advisors and consultants and to compensate them for their services.

The Nominating and Corporate Governance Committee met three times during 2024.

General Committee Information. A copy of each of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee Charters is available on our website at http://www.fspreit.com under the heading “Investor Relations” and then under the subheading “Governance Documents” under “Corporate Information.” In addition, our Board adopted Corporate Governance Guidelines, a copy of which is available in the same place on our website.

Our Board may from time to time establish other special or standing committees to facilitate the management of Franklin Street Properties or to discharge specific duties delegated to a committee by the full Board.

Director Nomination Process

The process followed by the Nominating and Corporate Governance Committee to identify and evaluate director candidates includes requests to our directors and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by our directors. The Nominating and Corporate Governance Committee has established director qualification standards for consideration in recommending candidates to our Board. The Nominating and Corporate Governance Committee is responsible for reviewing with our Board, on an annual basis, the appropriate characteristics, skills and experience required for our Board as a whole and its individual members.

In evaluating the suitability of individual candidates (both new candidates and current members of our Board), the Nominating and Corporate Governance Committee, in recommending candidates for election, and our Board, in approving the nomination of (and, in the case of vacancies, electing) such candidates, may take into account a variety of subjective factors, including, without limitation:

| (1) | personal and professional integrity, ethics and values;

| (2) | experience in corporate management, such as serving as an officer or former officer of a publicly-held company, and a general understanding of marketing, finance and other elements relevant to the success of a publicly-traded company in today’s business environment;

| (3) | experience in our industry and/or in an industry or industries that may be beneficial to us;

| (4) | experience as a board member of another publicly-held company;

| (5) | academic expertise in an area of our operations;

| (6) | practical and mature business judgment, including ability to make independent analytical inquiries; and

| (7) | any relationships, financial, professional or social in nature, that a candidate may have with members of management or other board members in so far as they may affect the independence of such candidate.

Consideration of Board Diversity. Our Corporate Governance Guidelines provide that, when evaluating candidates for nomination as new directors, the Nominating and Corporate Governance Committee will ensure that the initial list from which new directors are chosen (the “Initial List”) includes (but need not be limited to) qualified candidates reflecting a diversity of race, ethnicity and gender (and any third-party consultant requested to furnish an Initial List will be asked to include such candidates). In addition, in February 2023, our Board agreed that we would seek to fill the next vacancy on our Board with a qualified gender diverse candidate.

| FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT | 27

CORPORATE GOVERNANCE

The Nominating and Corporate Governance Committee and our Board believe that diversity with respect to viewpoint, skills and experience also should be an important factor in board composition. The Nominating and Corporate Governance Committee and our Board discuss diversity considerations in connection with each potential nominee, as well as on a periodic basis in connection with the composition of our Board as a whole. The Nominating and Corporate Governance Committee and our Board do not assign specific weight to particular factors, and no particular factor is a prerequisite for each prospective nominee. The Nominating and Corporate Governance Committee and our Board believe that the backgrounds and qualifications of its directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our Board to fulfill its responsibilities. Our Board evaluates each individual in the context of our Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee also considers the director’s past attendance at meetings and participation in and contributions to the activities of our Board and Board refreshment objectives.

Board Refreshment

Board refreshment over time assists the Board in maintaining an appropriate balance of tenure, diversity, experience, skills and new ideas needed to provide effective oversight in light of the Company’s current and future strategic needs. The Company benefits when there is a mix of directors with a history of service with the Company and newer directors who bring a fresh perspective and new ideas.

Stockholder Recommendations and Board Nominations

Stockholders may recommend individuals to our Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials to our principal office, 401 Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, Attn: Scott H. Carter, Secretary. Assuming that appropriate biographical and background material has been provided on a timely basis, our Nominating and Corporate Governance will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others. If our Board determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included in our proxy card for the next Annual Meeting.

Stockholders also have the right under our bylaws to directly nominate director candidates, without any action or recommendation on the part of our Nominating and Corporate Governance Committee or Board, by following the procedures set forth below under “Other Information—Stockholder Proposals.”

Stockholder Power to Amend Bylaws

The Company’s bylaws provide stockholders with the power to amend the Company’s bylaws by the affirmative vote of a majority of all votes entitled to be cast on the matter pursuant to a binding proposal that is properly submitted by stockholders for approval at a duly called annual or special meeting of stockholders.

Anti-Hedging Policy

Our Anti-Hedging Policy prohibits any director, officer or employee of FSP, or family member of any of the foregoing who share the same address as, or are financially dependent on, any of the foregoing, or any other person who shares the same address as any of the foregoing, other than a tenant or employee, and including any and all corporations, partnerships, trusts or other entities owned or controlled by any of the foregoing, from engaging in short sales of Company securities, including short sales “against the box”, or purchases or sales of puts or calls involving Company securities.

DIRECTOR COMPENSATION AND STOCK OWNERSHIP REQUIREMENTS

DIRECTOR COMPENSATION AND STOCK OWNERSHIP REQUIREMENTS

The Compensation Committee of the Board is responsible for reviewing and recommending to the Board the form and amount of compensation for our non-employee directors. In May 2024, the Compensation Committee recommended, and the Board adopted, the following changes to the compensation program for non-employee directors:

Non-employee Director Compensation
Annual Cash Retainer | $30,000 |
Additional Annual Cash Retainer – Lead Independent Director | $7,500 |
Additional Annual Cash Retainer – Chair of the Audit Committee | $7,500 |
Additional Annual Cash Retainer – Chair of the Compensation Committee | $5,000 |
Additional Annual Cash Retainer – Chair of the Nominating and Corporate Governance Committee | $5,000 |
Annual Grant of FSP Common Stock (1) | $45,000 |

| (1) | Reflects the grant date fair value. Fair value is the closing price of FSP Common Stock on the date of the grant, which is the tenth business day following the Annual Meeting.

Our Annual and Additional Cash Retainers are paid to our non-employee directors in four equal installments each year. We also reimburse our non-employee directors for expenses incurred by them in connection with attendance at Board meetings.

2024 Non-Employee Director Compensation

In May 2024, the Compensation Committee recommended, and the Board agreed, that changes to the compensation of our non-employee directors were advisable. The changes (1) decreased the annual cash retainer from $56,250 to $30,000, (2) reduced the additional annual cash retainer for the Lead Independent Director from $15,000 to $7,500, (3) reduced the additional annual cash retainer for the Chair of the Audit Committee from $15,000 to $7,500, (4) reduced the additional annual cash retainer for the Chair of the Compensation Committee from $10,000 to $5,000, (5) established an additional annual cash retainer for the Chair of the Nominating and Corporate Governance Committee in the amount of $5,000, and (6) permanently reduced the amount of the annual grant of FSP Common Stock from $56,250 to $45,000. The Compensation Committee and the Board determined that such changes were appropriate in order to reduce general and administrative expenses and in light of the broad macroeconomic factors that negatively impacted the business operations, operating results and stock performance of Franklin Street Properties.

Non-employee Director Stock Ownership Requirements

The Board believes that all non-employee directors should maintain a meaningful personal financial stake in the Company to align their long-term interests with those of our stockholders. Pursuant to our Corporate Governance Guidelines, non-employee directors are required to own shares of Common Stock valued at five times the cash portion of their Annual Cash Retainer (excluding any Additional Cash Retainers payable for serving as a committee chair or attendance at meetings).

For purposes of determining compliance with these requirements, the “value” of Common Stock shall be determined using the greater of (i) the actual cost basis of such shares or (ii) the Company’s average closing stock price for the preceding calendar year.

Non-employee directors serving as of February 7, 2014 (the date of initial adoption of these requirements) had until February 7, 2021, seven years following the initial adoption of these requirements, to meet the minimum ownership requirements. Non-employee directors who are elected or appointed after the initial adoption of these requirements will have seven years from the time they are elected or appointed to meet the minimum ownership requirements.

If an individual becomes subject to an increased ownership amount due to an increase in the Annual Cash Retainer, the individual is expected to satisfy the incrementally higher ownership amount within seven years of the effective date of the increased requirement.

PROPOSAL THREE – ADVISORY VOTE ON EXECUTIVE COMPENSATION

PROPOSAL THREE — ADVISORY VOTE ON EXECUTIVE COMPENSATION

We are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as “say-on-pay,” is required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which added Section 14A to the Exchange Act. After taking into consideration the voting results of the 2023 Annual Meeting of Stockholders when our stockholders voted in favor of holding future advisory votes on the compensation of our Named Executive Officers every year, and the prior recommendation of our Board of Directors in favor of holding such advisory votes every year, we will hold advisory votes on the compensation of our Named Executive Officers every year.

Our executive compensation programs are designed to attract, motivate, and retain our executive officers, who are critical to our success. Under these programs, our Named Executive Officers are rewarded for the achievement of our financial and strategic goals and for driving corporate financial performance and stability. The “Executive Compensation” section of this Proxy Statement, including “Compensation Discussion and Analysis,” describes in detail our executive compensation program and the decisions made by the Compensation Committee and the Board with respect to the year ended December 31, 2024. Highlights of our executive compensation program include the following:

| ● | Our base salary amounts are generally lower than industry standard levels.

| ● | None of our executive officers has an employment agreement.

| ● | Except in the case of a change-in-control of Franklin Street Properties, we are not obligated to pay severance or other enhanced benefits to executive officers upon termination of their employment.

| ● | We do not offer stock options, restricted stock awards, deferred compensation, non-equity incentive plan compensation or perquisites, which we believe keeps our compensation simple and straightforward.

Our Board of Directors is asking stockholders to approve a non-binding advisory vote on the following resolution:

RESOLVED, that the compensation paid to the Company’s Named Executive Officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and any related material disclosed in the Proxy Statement, is hereby approved.

This proposal is non-binding. The outcome of this advisory vote will not overrule any decision by the Company or the Board (or any committee thereof), create or imply any change to the duties of the Company or the Board (or any committee thereof), or create or imply any additional duties for the Company or the Board (or any committee thereof). However, our Compensation Committee and Board value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our Named Executive Officers.

Recommendation

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE NON-BINDING RESOLUTION APPROVING OUR EXECUTIVE COMPENSATION AS DISCLOSED IN THIS PROXY STATEMENT. PROPERLY AUTHORIZED PROXIES SOLICITED BY THE BOARD WILL BE VOTED FOR THIS PROPOSAL UNLESS INSTRUCTIONS TO THE CONTRARY ARE GIVEN.

COMPENSATION DISCUSSION AND ANALYSIS

COMPENSATION DISCUSSION AND ANALYSIS

Overview

It is critical that we be able to attract, motivate and retain highly talented individuals at all levels of the organization. We believe that compensation levels should be competitive enough to attract and retain experienced and capable leaders and motivate those individuals to achieve exceptional results and reward them for being instrumental in reaching our strategic goals. At the same time, we believe in simplicity and maintaining compensation at responsible levels. For 2024, the compensation of executives consisted of the same four components as were provided to all of our employees: (1) base salary; (2) the potential for a cash bonus; (3) matching for individual 401(k) plan contributions; and (4) the potential for a payment or payments under our change-in-control program. Although our executives are eligible to be granted awards of Common Stock under our 2002 stock incentive plan, we have not made any awards to executives under the plan since our initial listing on the American Stock Exchange (now NYSE American) in June 2005. In addition, we do not offer stock options, restricted stock awards, deferred compensation, non-equity incentive plan compensation or perquisites. None of our employees have employment agreements and, except for the Chief Executive Officer, we do not have any policies that require any of our employees to own our Common Stock. Pursuant to our Corporate Governance Guidelines, the Chief Executive Officer is required to own shares of Common Stock valued at six times his base salary.

Our executive officers consist of the Chief Executive Officer, the Chief Financial Officer, the President and Chief Investment Officer, the General Counsel, the President of FSP Property Management LLC and the Chief Operating Officer. For the fiscal year ended December 31, 2024, our Named Executive Officers were George J. Carter, our Chief Executive Officer; John G. Demeritt, our Executive Vice President, Chief Financial Officer and Treasurer; Jeffrey B. Carter, our President and Chief Investment Officer; John F. Donahue, Executive Vice President and President of FSP Property Management LLC; and Scott H. Carter, our Executive Vice President, General Counsel and Secretary.

We have reviewed our compensation policies and practices for all employees and concluded that any risks arising from our policies and programs are not reasonably likely to have a material adverse effect on Franklin Street Properties.

The objectives of our executive compensation programs

Our Compensation Committee bases our executive compensation programs on the same core objectives that guide us in establishing all of our compensation programs:

| ● | Compensation should promote the achievement of our business goals and maximize corporate performance and shareholder returns.

| ● | Compensation should be based on the principles of competitive and fair compensation and sustained performance.

| ● | Compensation should be based on the level of job responsibility, individual performance and corporate performance. As employees advance to higher levels within the organization, an increasing proportion of their compensation should be linked to corporate performance and enhancing shareholder value.

| ● | Compensation should reflect the value of the job in the marketplace. Compensation should be competitive with other employers that compete with us for talent so that we continue to be able to attract and retain highly talented employees.

| ● | Compensation should reward performance. Our compensation programs should deliver competitive compensation for excellent individual and corporate performance. Similarly, our compensation programs should deliver less compensation, including the possibility of no cash bonus, in the event that individual and/or corporate performance fall short of expectations.

| ● | Compensation should be equitable. We strive to achieve equitable distributions both for compensation of individual officers and between officers and other employees throughout the organization.

| ● | Compensation and benefit programs should be designed to attract, motivate and retain highly talented employees who are interested in building a career with us.

38 | FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT |

COMPENSATION DISCUSSION AND ANALYSIS

What our executive compensation programs are designed to reward and how we determine the amount (and, where applicable, the formula) for each element to pay

Decisions regarding executive compensation are based on various subjective performance criteria, including corporate and individual performance.

Our Compensation Committee has established a number of processes to assist it in ensuring that our executive compensation program achieves its objectives. Among those are:

| ● | In 2019, the Compensation Committee retained FPL Associates L.P., an independent compensation consulting firm, to review and evaluate our executive and non-employee director compensation programs. The review and evaluation included defining a peer group of companies, benchmarking our compensation programs against the peer group, and providing market data and advice regarding executive and director compensation plan design.

| ● | Consideration of various measures of corporate performance, including without limitation, the extent to which strategic and business plan goals are met, net debt, the amount of debt repaid, gross proceeds from property dispositions, the amount (and terms) of space leased, performance of properties in our portfolio, gains or losses on property dispositions, levels of earnings, funds from operations, or FFO, dividends paid, total stockholder return and estimated net asset value. Our Compensation Committee does not apply a formula or assign these performance measures relative weights. Instead, it makes a subjective determination after considering such measures collectively.

| ● | Consideration of individual performance. The members of the Compensation Committee meet with the Chief Executive Officer annually at the beginning of the year to discuss both individual and corporate priorities for the current year. At that same meeting, the members of the Compensation Committee meet to conduct a review of the Chief Executive Officer’s performance over the past year based on various subjective performance criteria, including his contributions to individual and corporate priorities, his contribution to corporate performance, the degree to which teamwork and corporate values are fostered and other leadership accomplishments. This evaluation is shared with the Chief Executive Officer and is considered by the Compensation Committee in establishing the Chief Executive Officer’s compensation. With respect to the other Named Executive Officers, the members of the Compensation Committee oversee the evaluation of their performance and receive a compensation recommendation from the Chief Executive Officer. In reviewing and approving the compensation for each of the other Named Executive Officers, the Compensation Committee is not required to give specific weight to any particular criterion or performance metric. The Compensation Committee considers the compensation recommendation from the Chief Executive Officer and also exercises its own judgment based on various subjective performance criteria, including contributions to corporate performance, the degree to which teamwork and corporate values were fostered and other leadership accomplishments.

| ● | Comparison of our executive compensation programs as a whole and also a comparison of total executive compensation for each individual with the compensation practices of other companies in the real estate industry. Historically, the Compensation Committee has used the National Association of Real Estate Investment Trusts (NAREIT) Annual Compensation Survey for comparison purposes. To ensure that total compensation is competitive, the Compensation Committee uses the results of the comparison to establish general compensation guidelines. Our Compensation Committee does not apply a formula or assign the survey data relative weight. Instead, it makes a subjective determination for that individual after considering such results collectively.

| ● | Our stockholders approved each of the say-on-pay proposals in 2021, 2022 and 2023 by over 93% of votes cast. The Compensation Committee considered this support level in its determination to maintain similar compensation policies and elements of compensation in 2024.

Each element of compensation and why we choose to pay each element

| (a) | Base Salary

Executive officers are paid a base salary. We believe that a competitive base salary provides an important guaranteed element to compensation. We also believe that the payment of a competitive base salary is consistent with the compensation practices of other comparable companies.

| FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT | 39

COMPENSATION DISCUSSION AND ANALYSIS

| (b) | Cash Bonus

Executive officers are eligible for a cash bonus based on various subjective performance criteria, including corporate and individual performance. The payment of a cash bonus is purely discretionary based upon overall performance and the amount can vary from year to year. We believe that the opportunity to earn a competitive cash bonus provides a monetary incentive that encourages both corporate and individual performance. We also believe that the payment of a competitive cash bonus is consistent with the compensation practices of other comparable companies.

| (c) | 401(k) Matching

Executive officers are eligible to participate in our 401(k) plan. We offer all employees a 401(k) plan that, in 2024, allowed for salary deferrals of up to $23,000 per year (indexed for inflation), or up to $30,500 per year including catch-up provisions for individuals aged 50 or older. We matched up to 3% of an employee’s compensation (up to a compensation cap of $200,000) for plan year 2024 and will match up to 3% of employee compensation (up to a compensation cap of $200,000) for plan year 2025. Employees make their 401(k) contributions through payroll deductions with pretax dollars. All employees are eligible to participate in the plan immediately upon hiring. The employee’s elective deferrals are immediately vested upon contribution to the 401(k) plan, and the employee has sole decision making authority as to the investment of funds. We believe that our 401(k) plan provides a vehicle for our employees to plan for their long-term security and that such a plan ultimately leads to improved job performance. We also believe that our 401(k) plan is consistent with the compensation practices of other comparable companies.

| (d) | Change-in-Control Program

Except in the case of a change-in-control of Franklin Street Properties, we are not obligated to pay severance or other enhanced benefits to Named Executive Officers upon termination of their employment.

In February 2006, we adopted a change-in-control program for all our employees, including our executive officers. The program was adopted in response to merger and consolidation activity within the real estate/real estate investment trust industry and is intended to preserve employee morale and productivity and encourage retention in the event of an actual or rumored change-in-control of Franklin Street Properties. The program is also intended to align employee and shareholder interests by enabling employees to consider corporate transactions that are in the best interests of the shareholders and other constituents of Franklin Street Properties without undue concern over whether the transaction or transactions may jeopardize the employee’s own employment.

Although there are some differences in payment amounts depending on the employee’s job level, the basic elements of the program are comparable for all employees:

| ● | The program consists of two components: a fixed payment pursuant to a retention agreement between the employee and Franklin Street Properties and the potential for an additional discretionary payment pursuant to a discretionary plan.

| ● | The triggering event for both components is a change-in-control of Franklin Street Properties. A change-in-control of Franklin Street Properties, as defined in the plan, generally refers to a change in ownership or effective control of Franklin Street Properties or a change in ownership of a substantial portion of the assets of Franklin Street Properties.

| ● | Under the retention agreement component of the program, employees would receive a payment as soon as practicable following the closing of the change-in-control, but in no event more than thirty days following the closing of the change-in-control. Executive officers would receive payments equal to three years of their base salaries plus a bonus opportunity payment equal to three years of their base salaries. For purposes of the retention agreement component of the program, base salary refers to the base salary of the employee in effect at the time of the closing of the change-in-control. Payments under the retention agreements are subject to a possible reduction, if any, after the tax consequences of the payment are determined.

| ● | Under the discretionary plan component of the program, immediately prior to the closing of the change-in-control, our Board of Directors may (but is not obligated to) establish a discretionary pool of funds equal to 1% of the market capitalization of Franklin Street Properties immediately prior to the closing of the change-in-control less the

40 | FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT |

COMPENSATION DISCUSSION AND ANALYSIS

|  | total amount of payments to all employees under the retention agreement component of the program. Our Board of Directors would have complete discretion to award all, a portion or none of the discretionary plan pool of funds to any employees of Franklin Street Properties, including the executive officers. Payments under the discretionary plan component are subject to a possible reduction, if any, after the tax consequences of the payment are determined.

Prior to adopting our change-in-control program, management reviewed plans similar to our retention agreement component offered by approximately ten other publicly-traded real estate investment trusts and concluded that our triggering event was generally consistent with the peer group. Management did not review any plans that were comparable to our discretionary plan but concluded that, on balance, the total potential payout amounts under our change-in-control program are generally consistent with the range offered by the peer group.

Our Chief Executive Officer has voluntarily elected not to participate in the retention agreement component of our change-in-control program.

| (e) | Awards of Common Stock under our 2002 Stock Incentive Plan

Executive officers are eligible for awards of Common Stock under our 2002 stock incentive plan. The 2002 stock incentive plan permits our Board of Directors to award up to 2,000,000 shares of our Common Stock to eligible participants. Prior to our listing on the American Stock Exchange (now the NYSE American) in June 2005, our employees were not able to purchase our Common Stock, and we determined that it was necessary and appropriate to be able to compensate our employees with stock awards as a means of attracting, retaining and motivating key personnel and to align the interests of management and all personnel with those of our stockholders. All of our employees, officers and directors are eligible to participate in the plan. There have been no awards of Common Stock to executive officers under the 2002 stock incentive plan since we started listing our Common Stock on a stock exchange in June 2005, as employees are now able to purchase Common Stock in the open market. As of March 4, 2025, 1,365,886 shares of our Common Stock were available under the plan. Although we have not made any awards to executive officers under the 2002 stock incentive plan since 2005, we may determine in the future to grant stock awards to executive officers under the 2002 stock incentive plan or a new stock plan in order to attract, retain, or motivate our executives.

How each element and our decisions regarding that element fit into our overall compensation objectives and affect decisions regarding other elements

| Overview |

The Compensation Committee recognizes that broad macroeconomic factors continued to negatively impact both the business operations and the stock performance of many office REITs during 2024, including FSP. Within that relative context, the Compensation Committee believes that our executive officers worked diligently during 2024 to try to increase shareholder value through the sale of select properties, and met the goals of using disposition proceeds primarily for the repayment of debt, as well as leasing vacant space. More specifically, during 2024, our executive officers managed property dispositions that resulted in aggregate gross proceeds of approximately $100 million. As of December 31, 2024, our net debt (calculated by subtracting total cash, cash equivalents and restricted cash from total short-term and total long-term debt) was approximately $208 million* compared to approximately $277 million* as of December 31, 2023. During 2024, we repaid approximately $155 million of debt. During 2024, we also leased approximately 616,000 square feet of space compared to approximately 706,000 square feet during 2023.

| (a) | Base Salary

In reviewing base salaries for 2024, the members of the Compensation Committee applied the principles described above under “What our executive compensation programs are designed to reward and how we determine the amount (and, where applicable, the formula) for each element to pay.” Based upon the recommendation of the Chief Executive Officer, the Compensation Committee approved annualized base salary increases of approximately 3% for each of the executive officers other than the Chief Executive Officer. The above-described annualized base salary increases were effective on January 15, 2024. With respect to the Chief Executive Officer, for the reasons discussed above, the Compensation Committee did not make a recommendation for an increase in base salary to our Board of Directors. The last time that

* Net debt is a non-GAAP financial measure. See Appendix A for additional information regarding net debt and a reconciliation of net debt to its most directly comparable GAAP financial measure.

| FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT | 41

COMPENSATION DISCUSSION AND ANALYSIS

our Chief Executive Officer accepted a base salary increase was in February 2015. Our base salary amounts are generally lower than industry standard levels. Accordingly, compensation of these positions will be weighted proportionately greater towards year-end bonus amounts based upon corporate and individual performance.

| (b) | Cash Bonus

In awarding cash bonuses for 2024, the members of the Compensation Committee applied the principles described above under “What our executive compensation programs are designed to reward and how we determine the amount (and, where applicable, the formula) for each element to pay.” The Compensation Committee made a subjective determination that each officer’s area of responsibility and accountability (i.e., business unit) contributed to the Company’s performance during 2024, as a result of each person’s leadership and direction. It was further noted that each of these individuals was considered to be integral to the daily operations of Franklin Street Properties and of great value to Franklin Street Properties and firmly committed to doing what is in the best interests of our stockholders.

The Compensation Committee determined to continue its historical practice of awarding cash bonuses in respect of 2024 but has considered and may decide to award all or a portion of bonuses to executives in respect of future periods in the form of an equity award in lieu of cash. Based upon a recommendation from management, the Compensation Committee approved cash bonuses for 2024 for each of the executive officers other than the Chief Executive Officer at a level approximately 20% lower than those paid for 2023. The Compensation Committee determined to decrease cash bonus amounts for 2024 due to a variety of subjective factors, including without limitation, the price of our Common Stock, the level of property dispositions, net debt, the amount of debt repaid and leasing, and in order to further reduce general and administrative expenses. While the Compensation Committee recognized that broad macroeconomic factors negatively impacted both the business operations and the stock performance of many office REITs during 2024, the Compensation Committee determined that a downward adjustment to the cash bonus amounts for each of the executive officers other than the Chief Executive Officer was appropriate in light of the various adverse impacts that all FSP stakeholders experienced during 2024, and in order to further decrease general and administrative expenses. The Compensation Committee believes that the reduced cash bonus amounts are within the range of total compensation paid to executive officers with comparable qualifications, experience and responsibilities in the same or similar businesses and of comparable size and success as the Company.

The Compensation Committee also reviewed and evaluated the performance of the Chief Executive Officer during 2024 by applying the principles described above under “What our executive compensation programs are designed to reward and how we determine the amount (and, where applicable, the formula) for each element to pay.” Within the relative context of the broad macroeconomic factors that negatively impacted both the business operations and stock performance of many office REITS during 2024, including FSP, the Compensation Committee made a subjective determination that the combined business units performed well under the leadership, focus and discipline of the Chief Executive Officer. However, for the reasons described above, the Compensation Committee did not make a recommendation for a cash bonus for our Chief Executive Officer.

| (c) | 401(k) Matching

There were no proposals made to modify our 401(k) plan program in 2024.

| (d) | Change-in-Control Program

Because we determined that our change-in-control program continues to satisfy its original intended purpose, there were no proposals made to modify the program in 2024.

| (e) | Awards of Common Stock under our 2002 Stock Incentive Plan

Because we determined that we were able to adequately compensate the executive officers who make up the corporate management team with salary and cash bonuses in 2024, no Common Stock awards were made to executive officers in 2024.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

In February 2006, we adopted a change-in-control program for all our employees, including our executive officers. We adopted the program in response to merger and consolidation activity within the real estate/real estate investment trust industry, to preserve employee morale and productivity and to encourage retention in the event of an actual or rumored change-in-control of the Company. The program is also intended to align employee and shareholder interests by enabling employees to consider corporate transactions that are in the best interests of the shareholders and other constituents of the Company without undue concern over whether the transaction or transactions may jeopardize the employee’s own employment. For an overview of our change-in-control program, please refer to the discussion included under the heading “Compensation Discussion and Analysis – Each element of compensation and why we choose to pay each element – (d) Change-in-Control Program.”

Assuming that the closing of a change-in-control occurred on December 31, 2024, our Named Executive Officers would be entitled to payment of the following amounts under the retention agreement component of our change-in-control program:

| Potential Payment due under
Name and Principal Position | the Retention Agreement
George J. Carter, Chief Executive Officer (PEO) | N/A (1)
John G. Demeritt, Executive Vice President, Chief Financial Officer and Treasurer (PFO) | $ 1,880,130 (2)
Jeffrey B. Carter, President and Chief Investment Officer | $ 1,883,196 (2)
Scott H. Carter, Executive Vice President, General Counsel and Secretary | $ 1,635,348 (2)
John F. Donahue, Executive Vice President and President of FSP Property Management LLC | $ 1,588,338 (2)
TOTAL | $ 6,987,012

NOTES

| (1) | George J. Carter has voluntarily elected not to participate in the retention agreement component of our change-in-control program.

| (2) | These are lump-sum payments equal to three years of base salaries plus a bonus opportunity payment equal to three years of base salaries. The payment amounts are subject to a possible reduction, if any, after the tax consequences are determined.

Under the discretionary plan component of our change-in-control program, our Board of Directors has the right, but not the obligation, to establish a discretionary pool of funds equal to 1% of our market capitalization immediately prior to the closing of the change-in-control. On December 31, 2024, there were 103,566,715 shares of our Common Stock outstanding and the closing price per share of our Common Stock was $1.83. Accordingly, on December 31, 2024, our market capitalization was $189,527,088, and 1% of our market capitalization equaled $1,895,271. Because the total amount of payments due and payable to all of our employees (including our Named Executive Officers) under the retention agreement component of our change-in-control program at December 31, 2024 exceeded 1% of our market capitalization at December 31, 2024, no funds would have been available for our Board of Directors to award under the discretionary plan component of our change-in-control program at December 31, 2024. As is the case with the retention agreement component of our change-in-control program, any payments under the discretionary plan component are subject to a possible reduction, if any, after the tax consequences are determined.

| (1) | For all years, Mr. George J. Carter served as our PEO and Mr. John G. Demeritt, Mr. Jeffrey B. Carter, Mr. Scott H. Carter and Mr. John F. Donahue served as the Other NEOs.

| (2) | For all years, the peer group is the FTSE NAREIT Equity Office Index.

| (3) | While our Compensation Committee employs a subjective approach to the consideration of various measures of corporate performance, for 2024, the Company identified net debt as the most important financial performance measure used to link the compensation actually paid to the PEO and the Other NEOs for 2024 to the Company’s performance. Net debt is a non-GAAP financial measure. See Appendix A for additional information regarding net debt and a reconciliation of net debt to its most directly comparable GAAP financial measure.

The following table lists the seven most important financial performance measures used by the Company to link compensation actually paid to the PEO and the Other NEOs in 2024 to the Company’s performance:

Net debt
Debt repaid
Gross proceeds from property dispositions
Amount (and terms) of space leased
Funds from operations (FFO)
Total stockholder return
Estimated net asset value

In the “Compensation Discussion and Analysis” section of this Proxy Statement, we provide greater detail on the elements of our executive compensation program and our compensation philosophy. We believe the Company’s executive compensation program and the executive compensation decisions included in the 2024 Summary Compensation Table and related disclosures appropriately reward our PEO and the Other NEOs for Company and individual performance and assist the Company in retaining our senior leadership team.

The annual total compensation of our median employee (excluding the Chief Executive Officer) for 2024(1) was $225,587. As disclosed in the Summary Compensation Table appearing on page 43, our Chief Executive Officer’s annual total compensation for 2024 was $306,000. Based on the foregoing, our estimate of the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all other employees was approximately 1.36 to 1.

TRANSACTIONS WITH RELATED PERSONS

TRANSACTIONS WITH RELATED PERSONS

Related Person Transaction Policy

Our Board of Directors adopted written policies and procedures for the review of any transaction, arrangement or relationship in which Franklin Street Properties is a participant, the amount involved exceeds $120,000 (or such lower amount as applies under Item 404(d)(1) of Regulation S-K if we qualify as a smaller reporting company at the time of the transaction), and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a related person, has a direct or indirect material interest.

If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a related person transaction, the related person must report the proposed related person transaction to our Chief Operating Officer or General Counsel.

The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by the Audit Committee of our Board of Directors. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the Audit Committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chairman of the Audit Committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to ratification by the committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually. A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the Audit Committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the committee will review and consider:

| ● | the related person’s interest in the related person transaction, including the related person’s position(s) with, or ownership in, a firm, corporation or other entity that is party to, or has an interest in, the related person transaction;

| ● | the approximate dollar value of the amount involved in the related person transaction;

| ● | the approximate dollar value of the amount of the related person’s interest in the related person transaction without regard to the amount of any profit or loss;

| ● | whether the related person transaction was undertaken in the ordinary course of our business;

| ● | whether the terms of the related person transaction are no less favorable to us than terms that could have been reached with an unrelated third party;

| ● | the purpose of, and the potential benefits to us of, the related person transaction; and

| ● | any other information regarding the related person transaction or the related person in the context of the proposed related person transaction that would be material to investors in light of the circumstances of the particular transaction.

The Audit Committee may approve or ratify the related person transaction only if the committee determines that, under all of the circumstances, the related person transaction is in, or is not inconsistent with, our best interests.

The Audit Committee may impose any conditions on the related person transaction that it deems appropriate.

No member of the Audit Committee shall participate in any review or approval (or ratification) of any related person transaction in which such member is the related person, any immediate family member of such member is the related person, or any significant shareholder with which such member is affiliated is the related person.

In addition to the transactions that are excluded by the instructions to the Securities and Exchange Commission’s related person transaction disclosure rule, our Board of Directors has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

| ● | interests arising only from the related person’s position and ownership level as a director of another corporation or organization that is a party to the transaction;

52 | FRANKLIN STREET PROPERTIES CORP. | 2025 PROXY STATEMENT |

TRANSACTIONS WITH RELATED PERSONS

| ● | interests arising only from the position and ownership level from direct or indirect ownership by the related person and all other related persons in the aggregate of less than a 10% equity interest (other than a general partnership interest) in another entity which is a party to the transaction;

| ● | interests arising solely from the ownership of a class of our equity securities if all holders of that class of equity securities receive the same benefit on a pro rata basis;

| ● | a transaction that involves compensation to an executive officer if the compensation has been approved, or recommended to the Board of Directors for approval, by the Compensation Committee of the Board of Directors or a group of independent directors of Franklin Street Properties performing a similar function;

| ● | a transaction that involves compensation to a director for services as a director of Franklin Street Properties if such compensation will be reported pursuant to Item 402(k) of Regulation S-K;

| ● | a transaction that is specifically contemplated by provisions of Franklin Street Properties’ charter or bylaws;

| ● | with respect to a related person who is a significant stockholder or an immediate family member of a significant stockholder to us, interests arising from any indebtedness transaction;

| ● | a transaction where the rates or charges involved in the transaction are determined by competitive bids;

| ● | a transaction that involves the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental authority;

| ● | a transaction that involves services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services;

| ● | interests arising as a result of a related person serving at our request as an officer and/or director of another company, including single-purpose real estate investment trusts whose equity syndication we sponsored, which we refer to as Sponsored REITs; or

| ● | a transaction that involves the payment by a Sponsored REIT to Franklin Street Properties (or any wholly-owned subsidiary thereof) of customary fees including, without limitation, acquisition, syndication, sales commissions, interim financing, investor servicing fees and asset management fees.

The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.

The policy is available on our website at http://www.fspreit.com.

OTHER INFORMATION

OTHER INFORMATION

MATTERS TO BE CONSIDERED AT THE MEETING

The Board of Directors does not know of any other matters that may come before the Annual Meeting. However, if any other matters are properly presented at the Annual Meeting, it is the intention of the persons named in the accompanying proxy to vote, or otherwise act, in accordance with their discretion on such matters.

SOLICITATION OF PROXIES

All costs of solicitation of proxies will be borne by Franklin Street Properties. In addition to solicitations by mail or via the Internet, our directors, officers and employees, without additional remuneration, may solicit proxies by telephone, telegraph and personal interviews. Brokers, custodians and fiduciaries will be requested to forward proxy soliciting material to the owners of stock held in their names, and, as required by law, we will reimburse them for their out-of-pocket expenses in this regard.

STOCKHOLDER PROPOSALS

In accordance with Rule 14a-8 of the Exchange Act, proposals of stockholders intended to be included in our proxy statement and form of proxy for the 2026 Annual Meeting of Stockholders must be received by Franklin Street Properties at its principal office not later than December 4, 2025. In addition, according to our current bylaws, any stockholder proposal intended to be presented at an annual meeting, including nominations for election to the Board, but not considered for inclusion in our proxy statement relating to such meeting, must be received at Franklin Street Properties’ principal office not earlier than the 150th day nor later than 5:00 p.m., Eastern Time, on the 120th day prior to the first anniversary of the mailing date of the preceding year’s proxy materials. For the 2026 Annual Meeting of Stockholders, that means that a stockholder must deliver proper notice of a proposed nominee or action that is proposed to be presented at the 2026 Annual Meeting of Stockholders but not be included in the proxy statement for such meeting to the Secretary of Franklin Street Properties between November 4, 2025 and December 4, 2025. In addition to the timing of the delivery of the notice, our bylaws include specific information that must be provided (including the information required by Rule 14a-19 under the Exchange Act) and procedures that must be followed to submit a proposal.

IMPORTANT NOTICE REGARDING DELIVERY OF SECURITY HOLDER DOCUMENTS

The Company may participate in the practice of “householding” proxy statements, annual reports and Notices of Internet Availability of proxy materials, meaning that the Company delivers a single document to a household, even though two or more stockholders live under the same roof or a stockholder has shares registered in multiple accounts, unless the Company has received an instruction to the contrary from one or more of the stockholders. This practice enables the Company to reduce the expense of printing and mailing associated with proxy statements and reduces the amount of duplicative information a stockholder may currently receive.

The Company will promptly deliver a separate copy of any of the foregoing documents to a stockholder if a stockholder writes to or calls the Company at the following address or phone number: Franklin Street Properties Corp., 401 Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, (877) 686-9496. If a stockholder wants to receive separate copies of the annual report and proxy statement or Notice of Internet Availability of proxy materials in the future, or if the stockholder is receiving multiple copies and would like to receive only one copy for his or her household, said stockholder should contact the Company at the above address and phone number.

APPENDIX A: RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

APPENDIX A: RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

The Company defines net debt as total debt (the most comparable GAAP measure, calculated as debt excluding unamortized financing costs) less cash, cash equivalents and restricted cash. By subtracting the amount of cash, cash equivalents and restricted cash from total debt, the result provides an estimate of the contractual amount of borrowed capital to be repaid, net of cash, cash equivalents and restricted cash available to repay it. We believe that this calculation provides useful information to investors in understanding our financial condition and provides a more complete understanding of our leverage position and borrowing capacity.
