April 12, 2024
Dear Fellow BXP Stockholders,
You are cordially invited to attend the 2024 annual meeting of stockholders of Boston Properties, Inc. The annual meeting will be held on Wednesday, May 22, 2024 at 9:00 a.m., Pacific Time, at Salesforce Tower, 415 Mission Street, 55th Floor, San Francisco, CA 94105.
The proxy statement, with the accompanying formal notice of the meeting, describes the matters expected to be acted upon at the meeting. We encourage you to review these materials carefully and to use this opportunity to take part in BXP's affairs by voting on the matters described in the proxy statement. Following the formal portion of the meeting, we will provide a brief report on the operations of our company and our directors and management team will be available to answer appropriate questions from stockholders.
Among other matters to be voted upon at the meeting is the election of directors. This year, the Board is pleased to announce the nomination of Timothy J. Naughton for election to BXP’s Board. Tim is the Chairman of the Board of AvalonBay Communities, Inc., where he previously served as Chief Executive Officer. Our proxy statement includes more information about Tim, as well as our continuing directors nominated for election at the 2024 annual meeting.
On behalf of the BXP Board, we extend our sincere gratitude to Kelly A. Ayotte, who will not be standing for re-election in 2024 following six years of service on our Board. Kelly made significant contributions to BXP during her tenure, including serving as the Lead Independent Director and Chair of the Compensation Committee. The Board is deeply appreciative for her service and wishes her the best of luck as she seeks election to the office of Governor of New Hampshire.
Your vote is important. Your proxy or voting instruction card includes specific information regarding the several ways to vote your shares. We encourage you to vote as soon as possible, even if you plan to attend the meeting. You may vote over the internet, by telephone or by mail.
Thank you for your continued support of BXP.

BXP / 2024 Proxy Statement 1

/Proxy Summary
Director Succession
Led by our Nominating and Corporate Governance ("NCG") Committee, our Board of Directors remains focused on ensuring (1) a smooth transition when directors retire or otherwise leave our Board and (2) that the composition of our Board is systematically refreshed so that, taken as a whole, it has the desired mix of skills, experience, continuity, reputation and diversity relevant to our strategic direction and operating environment, as well as the knowledge, ability and independence to continue to deliver the high standard of governance and oversight expected by investors. For more information on this process, see “Corporate Governance—Board Refreshment Philosophy” beginning on page 30 of this proxy statement.
Consistent with this approach, since 2016, our Board nominated, and our stockholders elected, seven new directors, and our Board of Directors is delighted to nominate a new candidate – Mr. Timothy J. Naughton – for election to our Board at the 2024 annual meeting of stockholders. Ms. Kelly A. Ayotte, a director of BXP since 2018, is not standing for re-election.
Of the eight, first-time nominees for director since 2016, four (50%) were women and two (25%) were African American. Mr. Naughton was initially recommended for consideration by Messrs. Lustig and Thomas.

BXP / 2024 Proxy Statement 7

https://cdn.kscope.io/41460b0ebcf9f72e1ce1121eed807136-BXP_Logo_Horizontal-Color-RGB-1.jpg
Proposal 1 / Election of Directors
BXP is currently governed by an eleven-member Board of Directors. At the 2024 annual meeting of stockholders, directors will be elected to hold office for a one-year term expiring at the 2025 annual meeting of stockholders. Directors hold office until their successors are duly elected and qualified, or until their earlier resignation or removal. Any director appointed to fill a vacancy on our Board of Directors will hold office for a term expiring at the next annual meeting of stockholders following such appointment.
Following the recommendation of the NCG Committee, our Board of Directors nominated the following directors for election at the 2024 annual meeting of stockholders:
Board of Directors NomineesBruce W. DuncanCarol B. Einiger
Diane J. HoskinsMary E. Kipp
Joel I. KleinDouglas T. Linde
Matthew J. LustigTimothy J. Naughton
Owen D. ThomasWilliam H. Walton, III
Derek Anthony (Tony) West
Each nominee other than Mr. Naughton currently serves as a director of BXP. In making its recommendations, the NCG Committee considered a number of factors, including its criteria for Board membership, which include the minimum qualifications that must be possessed by a director candidate in order to be nominated for a position on our Board. Our Board of Directors anticipates that, if elected, the nominees will serve as directors. However, if any person nominated by our Board of Directors is unable to serve or for good cause will not serve, the proxies will be voted for the election of such other person as the Board may recommend.
Vote Required and Majority Voting Standard
Our By-laws provide for a majority voting standard. This means that, in an uncontested election, nominees for director are elected if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election. The majority voting standard would not apply in contested elections, which, generally, will include any situation in which BXP receives a notice that a stockholder has nominated a person for election to our Board of Directors at a meeting of stockholders that is not withdrawn on or before the tenth day before we first mail the notice for such meeting to the stockholders.
The majority voting standard will apply to the election of directors at the 2024 annual meeting of stockholders. Accordingly, nominees for director will be elected if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election. Broker non-votes, if any, and abstentions will not be treated as votes cast.
8 BXP / 2024 Proxy Statement

Proposal 1/
Our Corporate Governance Guidelines contain a related resignation policy, under which a director who fails to receive the required number of votes for re-election will tender his or her resignation to our Board of Directors for its consideration. The NCG Committee will then act on an expedited basis to determine whether it is advisable to accept the director’s resignation and will submit its recommendation for prompt consideration by our Board of Directors. Our Board of Directors will act on the tendered resignation within 90 days following certification of the stockholder vote and will promptly and publicly disclose its decision. Any director whose resignation is under consideration will abstain from participating in any decision regarding his or her resignation. If the resignation is not accepted, the director will continue to serve until the next annual meeting of stockholders and until the director’s successor is duly elected and qualified or until the director’s earlier resignation or removal. The NCG Committee and our Board of Directors may consider any factors they deem relevant in deciding whether to accept a director’s resignation.
https://cdn.kscope.io/41460b0ebcf9f72e1ce1121eed807136-bxp-20240412_g35.gif
Recommendation of the Board
The Board of Directors unanimously recommends a vote “FOR” each of its nominees: Bruce W. Duncan, Carol B. Einiger, Diane J. Hoskins, Mary E. Kipp, Joel I. Klein, Douglas T. Linde, Matthew J. Lustig, Timothy J. Naughton, Owen D. Thomas, William H. Walton, III, and Derek Anthony (Tony) West. Properly authorized proxies solicited by the Board of Directors will be voted “FOR” each of the nominees unless instructions to the contrary are given.

/Proposal 1
Summary of Board Nominee Qualifications and Experience
In addition to the minimum qualifications that our Board of Directors believes are necessary for all directors, the following chart highlights some of the key qualifications and experience that our Board believes are relevant to the effective oversight of BXP and the execution of our long-term strategy. A mark for an attribute indicates that the nominee gained the attribute through a current or prior position other than his or her service on the BXP Board of Directors. Our Board did not assign specific weights to any of these attributes or otherwise formally rate the level of a nominee’s attribute relative to the rating for any other potential nominee or any other person. The absence of a mark for an attribute does not necessarily mean that the nominee does not possess that attribute; it means only that when the Board considered that nominee in the overall context of the composition of our Board of Directors, that attribute was not a key factor in the determination to nominate that individual. Further information on each nominee’s qualifications and relevant experience is provided in the individual biographical descriptions below.

22 BXP / 2024 Proxy Statement

Proposal 1/
Director Independence
Under the rules of the NYSE, a majority of the Board of Directors must qualify as “independent directors.” To qualify as an “independent director,” the Board must affirmatively determine that the director has no material relationship with us (either directly or as a partner, stockholder or officer of an organization that has a relationship with us). Our Board of Directors established categorical standards to assist it in making the required independence determinations.
Under these categorical standards, any relationship with us shall be deemed not material if:
1.The relationship does not preclude a finding of independence under Section 303A.02(b) of the NYSE Listed Company Manual (the “NYSE Disqualifying Rules”); and
2.The relationship does not involve any of the following, whether currently existing or occurring since the end of the last fiscal year or during the past three fiscal years:
(a)a director being an executive officer of, or owning, or having owned, of record or beneficially in excess of ten percent (10%) equity interest in, any business or professional entity that has made during any of such fiscal years, or proposes to make during the Company’s current fiscal year, payments to the Company, an executive officer of the Company or an entity controlled by an executive officer of the Company for property or services in excess of five percent (5%) of: (i) the Company’s consolidated gross revenues for such fiscal year (or, in the case of proposed payments, its last fiscal year), or (ii) the other entity’s consolidated gross revenues for such fiscal year (or, in the case of proposed payments, its last fiscal year);
(b)a director being an executive officer of, or owning, or having owned, of record or beneficially in excess of ten percent (10%) equity interest in, any business or professional entity to which the Company, an executive officer of the Company or an entity controlled by an executive officer of the Company has made during any of such fiscal years, or proposes to make during the Company’s current fiscal year, payments for property or services in excess of five percent (5%) of: (i) the Company’s consolidated gross revenues for such fiscal year (or, in the case of proposed payments, its last fiscal year), or (ii) the other entity’s consolidated gross revenues for such fiscal year (or, in the case of proposed payments, its last fiscal year);
(c)a director or an immediate family member of the director being an officer, director or trustee of a charitable organization where the annual discretionary charitable contributions of the Company, an executive officer of the Company or an entity controlled by an executive officer of the Company in any single year to the charitable organization exceeded the greater of $1 million or two percent (2%) of that organization’s consolidated gross revenues for the fiscal year;
(d)a director or an immediate family member of a director being indebted to the Company, an executive officer of the Company or an entity controlled by an executive officer of the Company in an amount in excess of $120,000;
(e)a director being an executive officer, partner or greater than 10% equity owner of an entity, or being a trustee or a substantial beneficiary of a trust or estate, indebted to the Company, an executive officer of the Company or an entity controlled by an executive officer of the Company in an amount in excess of the greater of $120,000 or 5% of such entity’s total consolidated assets, or to whom the Company or an entity controlled by an executive officer of the Company is indebted (other than with respect to (i) any publicly traded debt securities of the Company or such entity or (ii) non-recourse loans secured by real estate where both the lender and the Company or such entity intend for the lender to transfer all right to, and control over, the loan within 12 months and the documentation includes customary provisions for loans targeted at the commercial mortgage backed securities (CMBS) or collateralized debt obligation (CDO) markets) in an amount in excess of 5% of the Company’s or such entity’s total consolidated assets;
(f)a transaction or currently proposed transaction (other than relating to the ownership of securities), which involved or involves the direct or indirect payment in a single year of in excess of $120,000 from the Company, an executive officer of the Company or an entity controlled by an executive officer of the Company to a director or an immediate family member of a director;
BXP / 2024 Proxy Statement 23

/Proposal 1
(g)a director or an immediate family member of a director being an executive officer, general or managing partner or owner of more than 10% of the outstanding equity securities of an entity that has a co-investment or is a joint venture partner with the Company where the amount of the entity’s equity investment in any single year exceeds the greater of $1 million or 2% of the total consolidated assets of the entity; or
(h)a director or an immediate family member of a director being an executive officer, general or managing partner or owner of more than 10% of the outstanding equity securities of an entity (other than the Company) in which an executive officer of the Company or an entity controlled by an executive officer of the Company is an executive officer, general or managing partner or owner of more than 10% of the outstanding equity securities of the entity.
For purposes of these standards, “immediate family” member has the same meaning as in the NYSE Disqualifying Rules.
Relationships not specifically deemed not material by the above categorical standards may, in the Board’s judgment, be deemed not to be material.
2024 Independence Determinations
The Board of Directors concluded that the following nine (9) incumbent directors and Mr. Naughton qualify as independent directors under NYSE rules because (1) none of them has any relationships with BXP or any executive officer of BXP that would disqualify him or her from being considered independent under the minimum objective standards contained in the NYSE rules and (2) none of them has any relationships other than those deemed immaterial by the Board of Directors.

BXP Directors

Kelly A. AyotteBruce W. Duncan
Carol B. EinigerDiane J. Hoskins
Mary E. KippJoel I. Klein
Matthew J. LustigWilliam H. Walton, III
Derek Anthony (Tony) West
In determining that Mr. Klein qualifies as an independent director, our Board considered that (1) Mr. Klein is the Chief Executive Officer of Retromer Therapeutics Corp., a start-up company that signed a lease agreement with BXP in September 2021 for approximately 2,700 square feet in the ordinary course of business, (2) in the professional opinion of a third-party real estate professional, the fixed rent and other financial obligations under the lease represented the fair rental value for the space, and (3) Mr. Klein had no direct pecuniary interest in the transaction. The lease agreement expired on December 31, 2023.
In determining that each of Ms. Ayotte and Messrs. Duncan and Naughton qualifies as an independent director for purposes of his or her service on the Compensation Committee, our Board considered that (1) each serves or previously served as a non-employee director or advisory board member for a company with which BXP has a commercial relationship and engaged in transactions in the ordinary course of business, (2) each transaction was on arms’-length terms and the director had no direct or indirect involvement in the transaction, and (3) the director had no pecuniary interest in the success of the transaction.

Consideration of Director Nominees
Securityholder Recommendations
The NCG Committee’s current policy is to review and consider any director candidates recommended by securityholders in compliance with the procedures established from time to time by the NCG Committee. All securityholder recommendations for director candidates must be submitted to our Secretary at Boston Properties, Inc., 800 Boylston Street, Suite 1900, Boston, Massachusetts 02199-8103, who will forward all recommendations to the NCG Committee. We did not receive any securityholder recommendations for director candidates for election at the 2024 annual meeting in compliance with the procedures set forth below. All securityholder recommendations for director candidates for election at the 2025 annual meeting of stockholders must be submitted to our Secretary on or before December 13, 2024 and must include the following information:
the name and address of record of the securityholder;
a representation that the securityholder is a record holder of our securities, or if the securityholder is not a record holder, evidence of ownership in accordance with Rule 14a-8(b)(2) under the Securities Exchange Act of 1934, as amended (the "Exchange Act");
the name, age, business and residential address, educational background, current principal occupation or employment, and principal occupation or employment for the preceding five (5) full fiscal years of the proposed director candidate;
a description of the qualifications and background of the proposed director candidate which addresses the minimum qualifications and other criteria for Board membership as approved by the Board from time to time;
a description of all arrangements or understandings between the securityholder and the proposed director candidate;
the consent of the proposed director candidate (1) to be named in the proxy statement relating to our annual meeting of stockholders and (2) to serve as a director if elected at such annual meeting; and
any other information regarding the proposed director candidate that is required to be included in a proxy statement filed pursuant to the rules of the SEC.
In addition, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act. No proxies are being solicited for director candidates other than the Company's nominees at the 2024 annual meeting.
Board Membership Criteria
The NCG Committee has established criteria for NCG Committee-recommended director nominees. These criteria include the following specific, minimum qualifications that the NCG Committee believes must be met by an NCG Committee-recommended nominee for a position on the Board:
the candidate must have experience at a strategic or policymaking level in a business, government, non-profit or academic organization of high standing;
the candidate must be highly accomplished in his or her respective field, with superior credentials and recognition;
the candidate must be well regarded in the community and must have a long-term reputation for high ethical and moral standards;
the candidate must have sufficient time and availability to devote to our affairs, particularly in light of the number of boards on which the candidate may serve;
the candidate’s principal business or occupation must not be such as to place the candidate in competition with us or conflict with the discharge of a director’s responsibilities to us and our stockholders; and
to the extent the candidate serves or has previously served on other boards, the candidate must have a history of actively contributing at board meetings.
BXP / 2024 Proxy Statement 25

/Proposal 1
In addition to the minimum qualifications for each nominee set forth above, the NCG Committee will recommend director candidates to the Board for nomination, or present director candidates to the Board for consideration, to help ensure that:
a majority of the Board of Directors will be “independent” as defined by the NYSE rules;
each of its Audit, Compensation and NCG Committees will be comprised entirely of independent directors; and
at least one member of the Audit Committee will have such experience, education and other qualifications necessary to qualify as an “audit committee financial expert” as defined by the rules of the SEC.
Finally, in addition to any other standards the NCG Committee may deem appropriate from time to time for the overall structure and composition of the Board, the NCG Committee may consider the following factors when recommending director candidates to the Board for nomination, or presenting director candidates to the Board for consideration:
whether the candidate has direct experience in the real estate industry or in the markets in which we operate; and
whether the candidate, if elected, assists in achieving a mix of Board members that represents a diversity of background (including geography, gender and ethnicity) and experience.
Identifying and Evaluating Nominees
The NCG Committee may solicit recommendations for director nominees from any or all of the following sources: non-employee directors, our Chief Executive Officer, our President, other executive officers, third-party search firms or any other source it deems appropriate.
The NCG Committee will review and evaluate the qualifications of any proposed director candidate that it is considering or has been recommended to it by a securityholder in compliance with the NCG Committee’s procedures for that purpose, and conduct inquiries it deems appropriate into the background of these proposed director candidates. In identifying and evaluating proposed director candidates, the NCG Committee may consider, in addition to the minimum qualifications for NCG Committee-recommended director nominees, all facts and circumstances that it deems appropriate or advisable, including, among other things, the skills of the proposed director candidate, his or her depth and breadth of business experience, his or her independence, the needs of our Board, and whether the candidate, if elected, assists in achieving a mix of Board members that represents a diversity of background and experience. Other than circumstances in which we may be legally required by contract or otherwise to provide third parties with the ability to nominate directors, the NCG Committee will evaluate all proposed director candidates that it considers or who have been properly recommended to it by a securityholder based on the same criteria and in substantially the same manner, with no regard to the source of the initial recommendation of the proposed director candidate.

Corporate Governance
BXP is committed to adopting and adhering to corporate governance policies and practices that foster effective leadership and independent oversight of management. The Board of Directors is responsible for broad corporate policy and overall performance of the Company through the oversight of management and stewardship of the Company. Among other duties, the Board is responsible for overseeing corporate strategy, authorizing investment and financing activities, and risk management for the Company. The Board appoints the Company’s officers, assigns responsibility for management of the Company’s operations to such officers, and monitors and reviews their performance.
Board Leadership Structure
BXP’s Policy on Board Leadership Structure
We do not have a firm policy with respect to whether or not the roles of Chairman of the Board and CEO should be separate or combined. Our Board of Directors believes it is important to maintain flexibility to determine its board leadership structure based on the best interests of the Company and its stockholders from time to time. As the following timeline shows, BXP has operated under both structures in the past.
History of Board Leadership
June 1997-Jan 2010
From our IPO in June 1997 until January 2010, the roles of Chairman and CEO were separate
Our founders, Mortimer B. Zuckerman and Edward H. Linde, served as Executive Chairman and CEO, respectively
Apr 2013
The roles of Chairman and CEO were again separated when Mr. Thomas was hired as CEO
Mr. Zuckerman continued to serve as Executive Chairman of the Board
May 2016
Mr. Zuckerman retired as Executive Chairman, and Mr. Zuckerman and Ivan G. Seidenberg did not stand for re-election
The Board conferred the honorary title of Chairman Emeritus upon Mr. Zuckerman
The independent directors selected Mr. Klein to serve as Lead Independent Director
May 2022
• The Board determined to again combine the roles of Chairman and CEO and appointed Mr. Thomas as Chairman
• The independent directors selected Ms. Ayotte to serve as Lead Independent Director
Jan 2010
The roles of Chairman and CEO were combined when Mr. Zuckerman assumed the role of CEO upon the passing of Mr. E. Linde
May 2014
The Board established a Lead Independent Director role
The independent directors selected Ivan G. Seidenberg to serve as the initial Lead Independent Director
May 2019
The Board appointed Mr. Klein to serve as its independent Chairman
July 2023
Ms. Ayotte stepped down as Lead Independent Director and the independent directors selected Mr. Klein to serve as Lead Independent Director
Regardless of the specific Board leadership structure in effect, the Company incorporates a strong, defined leadership role for an independent director. Our Board has determined, and our Corporate Governance Guidelines provide, that our Board leadership structure will include either an independent, non-executive Chairman of the Board or a Lead Independent Director.
BXP / 2024 Proxy Statement 27

/Corporate Governance
Specifically, our Corporate Governance Guidelines provide that it is the Board’s policy that if:
the positions of Chairman of the Board and CEO are held by the same person, or
https://cdn.kscope.io/41460b0ebcf9f72e1ce1121eed807136-bxp-20240412_g80.gif
the independent directors shall select an independent director to serve as
Lead Independent Director
the position of Chairman of the Board is held by a non-independent director, or
none of the directors has been elected to serve as Chairman of the Board,
Our Corporate Governance Guidelines further provide that an independent director selected to serve as Lead Independent Director will serve in that role until (1) he or she ceases to be an independent director or resigns from the position, (2) a successor is selected by a majority of the independent directors or (3) an independent director is serving as the Chairman of the Board. In addition, if the Chairman of the Board is an independent director, then he or she shall assume the responsibilities of the Lead Independent Director referenced below and there will not be a separate Lead Independent Director.
Duties and Responsibilities of the Lead Independent Director
The Board believes the roles, and therefore the duties and responsibilities, of the independent Chairman of the Board and Lead Independent Director should be, and at BXP they are, substantially similar, and they should further the same goals of ensuring effective leadership and independent risk oversight. In addition to responsibilities that may be assigned from time to time by the independent directors of the Board, the duties and responsibilities of a Lead Independent Director include:
Approving information sent to the Board
Approving Board meeting agendas and schedules to assure sufficient time for all agenda items
Coordinating the work of each Board committee with the activities of the full Board
Calling meetings of the independent directors and special meetings of the Board, as necessary
Presiding at all meetings of the Board at which the Chairman is not present, including executive sessions of independent directors
Attending meetings of Board committees regularly

Corporate Governance/
Board Leadership Structure Determinations & Disclosure
Our Board annually determines who will serve as its Chairman and considers, among other things, the skills, experiences and qualifications of our director nominees, the industries in which they gained their experience, the evolving needs of our Company, how well our leadership structure is functioning, the age and tenure of each director nominee and the views of our stockholders. The Board typically makes this determination during the first quarter of each year, and disclosure of the Board’s determination is made in the proxy statement used for the annual meeting of stockholders at which director nominees are elected, which is filed each year in late March or early-to-mid April. The proxy statement discloses (1) who the Board selected to serve as Chairman and (2) if the Chairman is also serving as CEO or is otherwise a non-independent director, or if no Chairman has been elected, the person selected by the independent directors to serve as the Lead Independent Director. Our Board considers the views of our stockholders regarding our board leadership structure as expressed through their respective voting policies, their actual votes at our annual meetings, and our discussions with them.
BXP’s 2024 Board Leadership Structure
Combined Role of Chairman & CEO
In 2022, following six years of Board leadership, Mr. Klein stepped down as Chairman of the Board and our independent directors determined that it was in the best interests of BXP and our stockholders to elect Mr. Thomas as its Chairman thus combining the role of Chairman and CEO. Mr. Thomas is a seasoned industry veteran with more than 35 years of real estate and executive leadership experience. He has deep financial and operational experience and extensive knowledge of the Company, the real estate industry and risk management practices gained from various executive and leadership roles. Our Board of Directors determined that it continues to be in the best interests of BXP and its stockholders to maintain the combined role of Chairman and CEO and re-appoint Mr. Thomas as Chairman. The independent directors believe Mr. Thomas is in the best position to identify key issues facing the industry and Company and effectively communicate with various internal and external constituencies about critical business matters, as demonstrated by his critical leadership in BXP’s responses to the rapidly evolving environment since March 2020 as a result of the COVID-19 pandemic and the economic volatility and market shifts that followed. In addition to acknowledging his superb leadership through the COVID-19 pandemic and the resulting economic and industry challenges that followed, the Board believes that appointing Mr. Thomas to serve as both Chairman and CEO confirms internally and externally the Board’s high confidence in his unified leadership and elevates Mr. Thomas’ stature within the industry to potentially generate additional market opportunities and better commercial outcomes for the Company and its stockholders.
Having Mr. Thomas serve as Chairman and CEO promotes clear accountability and strong leadership with one person setting the tone for our employees, investors, clients, vendors and other stakeholders and having primary responsibility for executing our strategy. As Chairman and CEO, Mr. Thomas works closely with the Lead Independent Director, Mr. Klein, to preserve transparency between management and the Board and serve as an effective bridge for communication between the Board and management on significant business developments and time-sensitive matters.
Lead Independent Director
The independent directors again selected Mr. Klein to serve as Lead Independent Director. In selecting Mr. Klein to serve as Lead Independent Director, the independent directors considered, among other things, Mr. Klein’s understanding of the Company and its business gleaned from his 11+ years of service on our Board and his track record during that time of actively contributing as a member of the Board, including his previous service as Chairman and as Lead Independent Director.
In addition to the clearly defined role of our Lead Independent Director and Mr. Klein’s experience and qualifications, our Board’s independent oversight is further bolstered by:
the overall composition of our Board of Directors and contributions from all of our independent directors: each current non-employee director is independent (9 out of 11 directors),
the independent committees of our Board of Directors: each of the Audit Committee, Compensation Committee and NCG Committee is led by independent committee chairs and is comprised solely of independent directors, and
BXP’s other corporate governance policies in effect.

BXP / 2024 Proxy Statement 29

/Corporate Governance
Board Refreshment Philosophy
Our Board is committed to maintaining an appropriate balance between director retention and refreshment. The Board believes that substantial benefits result from a sustained focus on the Company’s business, strategy and industry over a period of time and that continuity on the Board is essential to its effectiveness. Because it takes time to acquire sufficient Company-specific knowledge and commercial real estate development is by its nature long-term, our Board values the experience and institutional knowledge of our longer-serving directors.
However, our Board also values refreshment and believes that turnover in Board membership provides an opportunity to add significant value through the input of fresh ideas, new skills, experiences, and knowledge, and the diversity of perspectives. The Board also understands concerns among interested stakeholders that the independence of directors may be impaired by lengthy tenure. As a result, our Board strives to balance these competing perspectives through careful succession planning.
Because each director is elected to hold office for a one-year term expiring at the next annual meeting of stockholders, and in light of the benefits resulting from continuity on the Board, the Board does not believe it is in the best of interests of the Company or its shareholders to establish arbitrary term limits or limits on the overall tenure of a director. Similarly, the Board does not believe there is a direct correlation between age and the ability to contribute effectively as a director. Accordingly, the Board does not have a mandatory retirement age for directors.
In lieu of such limits, in February 2024 our Board amended our Corporate Governance Guidelines to include a set of guidelines to help ensure that the Board has the appropriate mix of director tenure and ages and that the Board continues to evolve and consider new ideas and viewpoints through the director nomination process. In each case, the guidelines are flexible, and the exact timing for any transition will depend on the needs of the Board at the time, the willingness of the incumbent directors to continue to serve, and the timing of the identification and nomination of a successor(s).
The guidelines include:
The Board believes that even well-performing directors who continue to contribute meaningfully to the Board should not serve indefinitely.
The Board believes its annual self-evaluation process has been, and will continue to be, important in determining whether to nominate incumbent directors for election to the Board, and therefore it will directly or indirectly affect the average tenure of the Company’s non-employee directors.
The Board will seek to manage its overall composition so that its non-employee directors have a range of different tenures with the goal of combining fresh thinking and new ideas with deep institutional knowledge of the Company’s business operations and risk oversight.
The Board will generally seek to manage, to the extent feasible, the annual turnover in its composition.
While the Board does not have a mandatory retirement age or a limit on the overall tenure of an individual non-employee director, after a non-employee director attains the age of 75 or has served as a director for more than 15 years, he or she should expect that, at that time or within the succeeding few years, the Board will not renominate him or her for election.
If (a) the Board nominates for re-election an incumbent director who has attained the age of 75 or served as a director for more than 15 years, (b) the incumbent director is re-elected and (c) the incumbent director subsequently resigns voluntarily prior to the end of his or her term in order to facilitate the appointment of a successor director, then the policy of the Board will be to accelerate the vesting of any outstanding, unvested time-based equity awards held by the incumbent director that otherwise would have vested at the end of his or her then-current term.
Board Committee Rotation
The NCG Committee also considers the periodic rotation of committee members and committee chairs to introduce fresh perspectives to the fulfillment of the committees' duties.
30 BXP / 2024 Proxy Statement

Corporate Governance/
Policy Against Overboarding
The term “overboarding” is commonly used to describe a situation that occurs when one person serves on too many boards, thereby diminishing his or her ability to serve the organization effectively. The focus on overboarding is therefore part of an attempt to improve the overall functioning of a board by ensuring that its members are fully engaged.
In recent years, some institutional investors have become increasingly concerned about directors' service on too many boards. Common concerns include:
The responsibilities of directors have become increasingly complex in recent years and require a greater time commitment.
In general, public company boards now have more committees than they historically had, and service on board committees requires even more time.
There are more demands for non-employees directors to engage with investors about corporate policies, such as governance and compensation.
Companies are subject to an ever-growing set of regulatory requirements, and there is an increasing focus on a board’s oversight of material risks and the need for directors to keep up-to-date on industry trends and other relevant topics, including cybersecurity threats, climate change and cultural shifts, to name just a few.
Similarly, BXP’s Board of Directors believes that directors must have sufficient time and availability to devote to the affairs of the Company, particularly in light of the number of other boards on which the directors may serve. Therefore, in evaluating the suitability of director candidates, including incumbent directors, and making its annual nominations of candidates for election as directors, the Board will consider, among other things, the employment status of individual directors (e.g., if a director is employed full time, he or she may have less capacity to serve on other boards than someone who is retired) and the nature of, and time involved in, a director’s service on other boards and their committees.
In addition to the foregoing qualitative considerations, the Company’s Board considered and adopted a policy that relies on numerical limits. The policy is included in the Company's Corporate Governance Guidelines and provides that, except as otherwise may be provided in a written agreement between the Company and a third party, without the prior approval of the Board:
a non-employee director of the Company shall not serve simultaneously on the boards of more than three (3) other public companies (i.e., such director shall not serve on more than four (4) public company boards, including the Company’s Board); and
a director of the Company that is also an executive officer of the Company shall not serve simultaneously on the board of more than one (1) other public company (i.e., an executive officer of the Company shall not serve on more than two (2) public company boards, including the Company’s Board).
Directors of the Company shall advise the Chairman or, if one is not elected, the Lead Independent Director, and the Chair of the NCG Committee in advance of accepting an invitation to serve on the board of directors or trustees of any other public company.
All of our Board’s nominees for election as directors at the 2024 annual meeting have confirmed that they satisfy this policy.
In addition, as required by NYSE listing standards, no member of the Audit Committee may simultaneously serve on the audit committees of more than three (3) issuers having securities registered under Section 12(b) of the Exchange Act, unless the Board determines that such simultaneous service would not impair the ability of the member to effectively serve on BXP's Audit Committee.

Board's Role in Risk Oversight
Our Board of Directors has overall responsibility for our risk oversight. The Board exercises its risk oversight throughout the year, both at the full Board level and through its committees. While the Board and its committees oversee key risk areas, the Company’s risk management is facilitated through a top-down and bottom-up communication structure whereby the Board provides oversight and direction from the top and, among other things, reviews the reports from its committees, management and outside advisors and consultants that identify any key existing and potential risks, as well as future threats or trends. Management is charged with the day-to-day management of risks, frequent assessment of the risk environment and regular reporting to the Board.
BXP’s risk management framework is designed to:
identify and understand critical risks in the Company’s business and strategy, including near-term, intermediate-term and long-term risks;
allocate responsibilities for risk oversight among the full Board and its committees to enhance the Board’s responsiveness and attention to specific risks based on the nature and immediacy of the risks assessed;
review with the Audit Committee, at least annually, the Company’s risk management processes to ensure they are functioning adequately (see “—Committee Roles in Risk Oversight—Audit Committee's Role in Risk Assessment” on page 35);
facilitate open communication between management and all directors serving on the Board; and
solicit feedback and advice from outside advisors and consultants to assess the effectiveness of our risk management framework and help ensure that we employ appropriate strategies to mitigate risks.
The Board fulfills its risk oversight function by, among other things, delegating to committees the oversight of certain specific risks as needed, staying informed about developments in our industry and other current events that may impact the Company, reviewing regular reports provided to the Board and applicable Board committees from management and outside advisors and consultants, discussing material risks and opportunities with management, and selecting director candidates with diverse experience and qualifications.
BXP / 2024 Proxy Statement 33

/Corporate Governance
Board of Directors
Our Board of Directors administers its risk oversight function through:
Regular periodic reports from management on key risks that we face, including, among others:
market conditions
client concentrations, credit worthiness and possible client bankruptcies
leasing activity and expected expirations
the status of development projects
compliance with debt covenants and credit ratings
management of debt maturities and interest-rate risk
access to debt and equity capital markets
existing and potential legal claims
environmental, social and governance risks
potential cyber incidents and intrusions
public health crises, pandemics and epidemics
succession planning
Required approval by our Board of Directors (or a committee thereof) of significant transactions and other matters, including, among others:
acquisitions and dispositions of properties
development and redevelopment projects
new borrowings, refinancings and guarantees of debt, and the use of hedging instruments to manage interest-rate risk
the appointment of all officers
the compensation of executive officers
transactions with related persons and conflicts of interest
Reports from the Audit, Compensation, NCG and Sustainability Committees, and other committees that may be established from time to time, on matters delegated to them
Reports from outside advisors and consultants, including environmental and climate-related experts, and cyber, legal, accounting and tax professionals, regarding various areas of potential risk
Committee Roles in Risk Oversight
The Board discharges its responsibility either directly or indirectly through its committees. While the full Board of Directors is primarily responsible for risk oversight, its committees monitor and address risks that are within the scope of a particular committee’s expertise, the committee’s charter or the resolution(s) appointing the committee. Issues escalated to the full Board may be addressed in several ways, as appropriate, depending on the risk assessed and immediacy required to address the risk. For example, oversight of risk may remain with the applicable committee of the Board, the Board may establish an ad hoc committee or direct an existing committee to oversee such matters, or the Board may ask management to present more frequently to the full Board on the issue.

Corporate Governance/
Board Committees
Our Board of Directors uses its committees to assist in risk oversight as follows:
Audit CommitteeCompensation Committee
The Audit Committee oversees risks related to:
the independence and performance of our independent auditors;
the integrity of our financial statements and internal control over financial reporting;
compliance with GAAP and management's use of estimates and judgments;
our use of non-GAAP financial measures;
cybersecurity;
REIT compliance;
pending and threatened litigation, legal and regulatory requirements, and insurance;
the performance of our internal audit function; and
our anti-fraud program.


The Compensation Committee oversees risks related to:
our ability to attract, retain and motivate our executive officers;
the use of compensation practices and plans to align the interests of our executives with those of our stockholders; and
the influence of incentive compensation on excessive risk-taking.

For more information, see “Compensation Discussion and Analysis—Other Compensation Policies—Assessment of Compensation-Related Risks” on page 100.
NCG CommitteeSustainability Committee
The NCG Committee oversees risks related to:
the composition, leadership and independence of the Board and its committees;
the general operations of the Board;
the process of conducting the annual Board and committee self-evaluations;
our compliance with our Corporate Governance Guidelines and applicable laws and regulations, including applicable rules of the NYSE; and
policies with respect to the consideration of director candidates recommended by stockholders.
The Sustainability Committee oversees risks related to:
environmental and climate action and resilience trends and issues;
our progress in achieving our sustainability goals and initiatives; and
regulatory compliance matters that may impact our sustainability objectives.
Absent an express delegation of authority from the Board, no one independent director, including the Lead Independent Director, has the authority to make decisions on behalf of the Company or override a decision of management. The role of our Lead Independent Director includes certain authorities (such as the authority to call meetings of the independent directors and special meetings of the Board, as necessary) that empower our independent directors to effectively discharge the Board's oversight responsibilities. Because of the role of our Board of Directors in risk oversight, our Board believes that any leadership structure that it adopts must allow it to effectively oversee the management of the risks relating to our operations. Our Board of Directors recognizes that there are different leadership structures that could allow it to effectively oversee the management of these risks. We believe our risk management framework is well-supported by our current board leadership structure and enables the Board to effectively manage such risks. See the discussion under the heading “—Board Leadership Structure” beginning on page 27 for a discussion of why our Board of Directors has determined that its current leadership structure is appropriate.
Audit Committee's Role in Risk Assessment
The Audit Committee oversees an annual risk assessment designed to identify and analyze risks to achieving BXP's business objectives. Among other things, the Audit Committee uses the results of the risk assessment to develop and oversee BXP's internal audit plan and inform the Board as to the material risks that warrant time and attention by the Board.
BXP / 2024 Proxy Statement 35

/Corporate Governance
Management's Role in Risk Oversight
We have not designated a single person to serve as the Company’s chief compliance officer; instead, we have internal processes, an effective internal control environment and a risk management framework that facilitate the identification and management of risks and regular communication with the Board. These processes include:
an Internal Audit Department that (a) reports directly to the Audit Committee, (b) is designed to enhance BXP’s operations through its objective, systematic and disciplined testing and evaluation of the internal controls applicable to BXP’s significant activities, systems and processes and (c) conducts an annual enterprise risk assessment involving all departments, functions and regions of the Company and reports the results directly to the Audit Committee,
regular internal meetings among senior management from multiple departments, including internal audit, risk management, legal and information systems/technology, responsible for specified risk management activities with regular reports to the Audit Committee,
a Disclosure Committee established to assist senior management in designing, establishing, maintaining, reviewing and evaluating BXP’s disclosure controls and procedures,
a Code of Business Conduct and Ethics that governs business decisions and actions taken by our employees and directors and that allows for the confidential and anonymous reporting of questionable business practices by employees and third parties, and
a comprehensive internal and external audit process.
As set forth in BXP’s Corporate Governance Guidelines, all directors have complete access to officers and employees of the Company, as well as the Company’s outside counsel, auditors and advisors.

Human Capital Management and Sustainability
Human Capital Management
Our employees are a significant distinguishing factor that sets BXP apart. As of December 31, 2023, we had 727 non-union employees (we had 836 employees, inclusive of union employees). Except as otherwise noted, all data provided in this Human Capital Management section refers to BXP’s non-union employee workforce as the unions control primary aspects of the hiring process. Our operational and financial performance depends on our employees' talents, energy, experience and well-being. Our ability to attract and retain talented people depends on a number of factors, including work environment, career development and professional training, compensation and benefits, and the health, safety and wellness of our employees. We have an established reputation for excellence and integrity; these core values are inherent in our culture and play a critical role in achieving our goals and overall success.
Diversity, Equity & Inclusion
We strive to create a diverse and inclusive workplace. It has been, and will continue to be, our policy to recruit, hire, assign, promote and train in all job titles without regard to race, national origin, religion, age, color, sex, sexual orientation, gender identity, disability, protected veteran status, or any other characteristic protected by local, state, or federal laws, rules, or regulations. By implementing this policy, we aim to ensure that all employees have the opportunity to make their maximum contribution to us and to their own career goals.
BXP’s Diversity, Equity & Inclusion Council (the “DEI Council”) is an executive-sponsored, employee-led, voluntary committee unified by BXP’s mission to promote diversity, equity, inclusion and transparency as part of our organization’s culture, decision-making practices and business activities, while also providing a mechanism for positive impact in the communities in which we operate. Since its formation in 2020, the DEI Council has grown to include more than 42 members across our six regions, and each member contributes to the overall mission through leadership in one or more of the DEI Council’s three committees – the Employee Engagement Committee, the Supplier Diversity & Engagement Committee and the Community Outreach Committee – and/or four employee resource groups (“ERGs”). Including ERG members, as of December 31, 2023, BXP’s DEI community consisted of 255 members, or 35% of BXP’s workforce.
The DEI Council in collaboration with BXP’s CEO, President and Human Resources Department annually identify actionable diversity goals and proposes initiatives to advance its mission. In 2023, the DEI Council focused on enhancing: (1) employees’ sense of belonging, (2) DEI education, (3) social responsibility, (4) transparency and communication and (5) governance. Throughout 2023, the DEI Council and BXP’s ERGs executed on numerous initiatives. BXP’s notable 2023 DEI activities include:

/Human Capital Management and Sustainability
Culture & Employee Engagement
We believe that the success of our business is tied to the quality of our workforce, and we strive to maintain a corporate environment without losing the entrepreneurial spirit with which we were founded more than 50 years ago.
By providing a quality workplace and comprehensive benefit programs, we recognize the commitment of our employees to bring their talent, energy and experience to us. Our continued success is attributable to our employees’ expertise and dedication. Our workforce, as referred to in this section, excludes intern employees and union employees for which the unions control primary aspects of the hiring process.
We periodically conduct employee engagement surveys to monitor our employees’ satisfaction in different aspects of their employment, including company performance, leadership, communication, career development and benefits offerings. Past employee responsiveness to the engagement surveys has been consistently high and the results help inform us on matters that our employees view as key contributors to a positive work experience. We intend to continue to periodically evaluate employee engagement as needed on a meaningful basis.
Another indicator of the success of our efforts in the workplace is the long tenure of our employees, 33% of whom have worked at BXP for ten or more years. The average tenure of our employees is approximately 9.2 years and that of our officers is 18.5 years. In 2023, our voluntary workforce turnover rate was 10.4%.
Career Development & Training
We invest significant resources in our employees’ personal and professional growth and development and provide a wide range of tools and development opportunities that build and strengthen employees’ leadership and professional skills. These development opportunities include in-person and virtual training sessions, in-house learning opportunities, various management trainings, departmental conferences, executive townhalls and external programs. We foster an environment of growth and internal promotion and strive for a best-in-class candidate experience for our internal applicants. Open positions are posted, and employees are highly encouraged to apply for promotion within the organization. For 2023, 12% of our employees were promoted to elevated roles within our organization. Of the employees promoted, 51% were women and 28% were ethnically diverse.
Sustainability
We actively work to promote our growth and operations sustainably and responsibly across our six dynamic gateway markets. BXP’s sustainability strategy is to conduct our business, the development, ownership and operation of new and existing buildings, in a manner that contributes to positive economic, social and environmental outcomes for our clients, shareholders, employees and the communities we serve. Our investment philosophy is shaped by our core strategy of long-term ownership and our commitment to our communities and the centers of commerce and civic life that make them thrive. We are focused on developing and maintaining healthy, high-performance buildings, while simultaneously mitigating operational costs and the potential external impacts of energy, water, waste, greenhouse gas (“GHG”) emissions and climate change. Positive social impact is also of great importance to BXP and our employees, which is exhibited by our commitments to charitable giving, volunteerism, public realm investments and promoting diversity, equity and inclusion in the workplace and our communities. Through these efforts, we demonstrate that operating and developing commercial real estate can be conducted with a conscious regard for the environment and broader society while mutually benefiting our stakeholders.
Industry Leadership
We continue to address the needs of our stakeholders by making efforts to maintain and improve our performance across three pillars: climate action, climate resilience and social good. BXP is a widely recognized industry leader in sustainability, and our 2023 highlights include:
BXP ranked among the top real estate companies in the GRESB assessment, earning an eighth consecutive 5-star rating. 2023 was the twelfth consecutive year that BXP earned the GRESB “Green Star” designation
BXP maintained an MSCI rating of “AA,” a CDP Climate Change score of “B ” and increased our CDP Supplier Engagement Rating to a "B-"
46 BXP / 2024 Proxy Statement

Human Capital Management and Sustainability/
BXP was named a member of the Dow Jones Sustainability Index (DJSI) North America for the third consecutive year. BXP was one of seven real estate companies that qualified and the only office REIT in the index, scoring in the 94th percentile of the real estate companies assessed for inclusion
BXP was recognized at the Bronze Level by Commercial Property Executive for “Best ESG Program”
BXP was named an ENERGY STAR Partner of the Year – Sustained Excellence Award Winner for the 4th consecutive year
BXP continued its tenure as an inaugural Platinum Level Green Lease Leader by the Institute for Market Transformation and the U.S. Department of Energy
Our leadership position is due, in part, to our establishment of environmental goals, the periodic reporting of progress toward our goals and the achievement of these goals. We have publicly adopted energy, emissions, water, building certification and waste goals that establish targets aligned with the United Nations Sustainable Development Goals. As of the end of 2022, the combined impacts of efficiency measures and renewable energy consumption resulted in a 39% decrease in energy use intensity and over 70% reduction in Scope 1 and Scope 2 GHG emissions intensity below a 2008 base year. We have also aligned our emissions reduction targets with climate science and in 2020 became the first North American office REIT to establish an emissions reduction target ambition in line with a 1.5°C trajectory, the most ambitious designation available at the time of submission under the Science Based Targets initiative. In April 2021, we affirmed our commitment to achieving carbon-neutral operations (for direct and indirect Scope 1 and Scope 2 GHG emissions) by 2025 from our occupied and actively managed buildings where we have operational control. BXP’s carbon-neutral goal progress and key performance indicator data is updated annually in our Sustainability and Impact Report, published in April.
We are focused on developing, owning and operating healthy and high-performance buildings. BXP is a corporate member of the U.S. Green Building Council® (“USGBC”) and has a long history of green buildings under USGBC’s Leadership in Energy and Environmental Design™ (LEED®) rating system. As of December 31, 2023, we had LEED-certified 33.4 million square feet of our total in-service portfolio, of which 92% was certified at the highest Gold and Platinum levels. In 2018, we announced a partnership with a leading healthy building certification system, Fitwel, to support healthy building design and operational practices across our portfolio, becoming a Fitwel Champion. We completed our Fitwel Champion commitments and have added 25.0 million square feet of Fitwel-certified buildings across our total in-service portfolio since 2018.
Climate Resilience
As a long-term owner and active manager of real estate assets in operation and under development, we take a long-term view of climate change risks and opportunities. We are focused on understanding how climate change may impact the performance of our portfolio and the steps we can take to increase climate resilience. We continue to evaluate the potential risks associated with climate change that could impact our portfolio and are taking proactive steps to plan for and/or mitigate such risks.
Governance
As a vertically integrated, full-service real estate company, we are engaged in addressing climate-related issues at all levels of our organization. Our Board of Directors has established a board-level Sustainability Committee to, among other things, increase Board oversight over environmental and sustainability issues, including climate-related risks and opportunities. The Board delegated to the Sustainability Committee the responsibility to oversee BXP’s sustainability program, which includes monitoring and addressing, as needed, environmental-, sustainability- and climate-related risks. Management’s role in assessing and managing climate-related risks, opportunities and initiatives is spread across multiple teams throughout our organization, including our executive leadership and our Sustainability, Risk Management, Development, Construction and Property Management Departments. BXP has a dedicated team of sustainability professionals focused on coordinating and collaborating across corporate and regional teams to advance environmental sustainability issues and initiatives.
Our approach to climate-related issues is also informed by robust stakeholder engagement. We are in frequent dialogue with investors, customers, community members, governmental policymakers, consultants and other non-governmental organizations. We are heavily involved in industry associations and participate in conferences and workshops covering sustainability and climate resilience topics. Through these engagements, we enhance our knowledge of climate-related issues and those issues that are most important to our stakeholders and industry best practices.
BXP / 2024 Proxy Statement 47

/Human Capital Management and Sustainability
Strategy
We have aligned our climate-related disclosures with the recommendations of the Task Force on Climate-Related Financial Disclosures (“TCFD”). The TCFD framework has informed the development of our strategy for identifying and managing both physical and transition risks associated with climate change. As defined by the TCFD framework, physical risks associated with climate change include acute risks (extreme weather-related events) and chronic risks (such as extreme heat and sea-level rise), and transition risks associated with climate change include policy and legal risks, and other technology, market and reputation-related risks.
We continue to proactively assess the potential risks that may impact the properties in our portfolio, gather information and monitor the evolving regulatory landscape related to climate change. Our process for assessing climate-related risks and their implications on our properties and business includes a climate change scenario analysis that was conducted in 2021 on our portfolio assets and will be updated in 2024. In particular, we engaged Moody’s ESG Solutions (formerly branded as the Four Twenty Seven Application), an independent provider of science-driven insights and analytics on climate risk, for its climate risk scoring to evaluate the forward-looking physical climate risk exposure of our entire portfolio. The scenario analysis and physical risk scoring were based on an RCP 8.5 emissions scenario, which is a worst-case, high-emissions scenario, under a time horizon up to 2040. The scenario analysis included all in-service assets owned by BXP and included climate events such as hurricanes, wildfires, heat, water stress, flooding and sea-level rise. We are also using climate risk data to identify potential risks during the new acquisition diligence process. The analysis of our portfolio in 2021 yielded no material findings.
We consider climate-related risks and opportunities in the context of the following time horizons: short-term (1-2 years), medium-term (3-10 years) and long-term (>10 years). Based on the foregoing process for evaluating climate-related risks, including the scenario analysis, we have identified (1) the following potential physical and transition risks associated with climate change that could impact our portfolio in the future across the stated time horizons and (2) our climate-related opportunities. We will continue to analyze the results of climate risk analyses, including the following risks and opportunities to understand our potential exposure and inform our climate resilience strategy and future investments, which include climate-related risk mitigation and initiatives.
Risk Management
BXP is committed to managing and avoiding the impacts of climate change. Our risk management program includes physical and transition risks, including both climate mitigation (resource efficiency and emissions reduction) and adaptation (integration of climate resilience into our investment decision-making). We are actively acquiring, developing and operating a geographically diverse portfolio of high-quality commercial real estate properties. Individual assets have unique risk profiles and insurance requirements. Through the processes of acquisition, development and operation of our in-service portfolio, our experienced real estate professionals are identifying risks, including business continuity risks, loss exposure related to extreme weather events and impacts of regulation, including permitting requirements, codes, and energy and carbon performance standards. The climate risk profile of each property is largely dependent on the property’s unique attributes, physical location and jurisdictional regulatory requirements.
Asset-Level Risk Management
We carry all-risk property insurance on our properties including those under development. Insurance coverage mitigates the impact on BXP from losses associated with natural catastrophes, such as floods, fires, earthquakes and wind events.
We are preparing for long-term climate risk by considering climate change scenarios and expect that we will continue to assess climate change vulnerabilities resulting from potential future climate scenarios and sea-level rise. We will continue to evaluate existing plans and procedures and proactively implement practical, cost-effective resiliency measures and infrastructure enhancements, including:
Business Continuity Plans
Emergency Response and Life Safety Plans
Emergency Evacuation Planning, Procedures and Drills
Client Engagement and Coordination
Life Safety Analysis

Onsite energy resources and distributed generation, storage and solar photovoltaic systems.
We are managing transition risks by benchmarking energy, carbon, water and waste performance at the asset level and are prioritizing interventions at underperforming assets. We develop, operate and maintain a large portfolio of buildings that are LEED, ENERGY STAR and/or Fitwel certified. As of December 31, 2023, 91% of our actively managed portfolio was certified under one or more of these frameworks. As a leader in green building, we will continue to make investments in building performance, energy efficiency and decarbonization.
Through our climate action efforts, we believe we can play a leading role in advancing the transition to a low-carbon economy and are taking action to decarbonize operations. GHG sources include the generated electricity and steam at offsite generation facilities, the onsite combustion of fuels (e.g., natural gas), and emissions associated with other business activities, including business travel and new development. We continue to explore and implement creative and cost-effective measures that reduce GHG emissions from our operations.
BXP became a proud signatory of the We Are Still In pledge after the U.S. withdrawal from the Paris Agreement and has aligned emissions reduction targets with climate science. In 2020, the SBTi Target Validation Team classified BXP’s emissions reduction target ambition and determined that it is in line with a 1.5°C trajectory, the most ambitious designation available at the time of submission. We are committed to achieving carbon-neutral operations, or net-zero carbon dioxide equivalent emissions, which includes direct and indirect Scope 1 and Scope 2 GHG emissions, by 2025 from our occupied and actively managed buildings where we have operational control.
BXP’s Carbon-Neutral Operations Strategy
Our strategy to achieve carbon-neutral operations includes the following goals:
1.Energy Efficient Operations – Approximately 1/3 of total carbon reductions by 2025 (below a 2008 base year) from energy conservation and efficient operations.
2.Renewable Energy – Advancement of onsite development of renewable energy systems and sourcing offsite renewable energy to meet 100% of our electricity needs by 2025.
3.Electrification – Explore and advance electrification, prioritizing electrification of new developments and replacement of onsite gas-fired systems at existing buildings at the end of their useful lives.
4.Carbon Offsets – To the extent necessary, offset any remaining emissions during the transition to carbon-free energy.
The resilience of our markets may depend on the action taken by cities to adapt transportation, energy, and communication infrastructure for extreme heat, weather events, sea-level rise and flooding. We will continue to encourage the adaptation of our cities and management of physical and transition risks by maintaining a voice in policy decision-making at the local level through direct engagement and/or advocacy through collective membership-based groups.
Metrics
We closely monitor energy consumption and associated GHG emissions and provide a detailed accounting of sustainability key performance indicators in our annual sustainability reporting. As of the end of 2022, the combined impacts of efficiency measures and renewable energy consumption resulted in a 39% decrease in energy use intensity and an over 70% reduction in Scope 1 and Scope 2 GHG emissions intensity below a 2008 base year. BXP’s carbon-neutral commitment includes direct and indirect Scope 1 and Scope 2 GHG emissions from our actively managed portfolio where we have operational control. Scope 1 and Scope 2 GHG emissions include emissions associated with landlord-controlled energy use within our multi-tenant buildings.
BXP / 2024 Proxy Statement 49

/Human Capital Management and Sustainability
Scope 1 GHG emissions include all emissions associated with the onsite combustion of fossil fuels for heating, hot water and standby generators. Scope 2 GHG emissions include all emissions associated with the offsite generation of electricity and steam. As our business continues to grow, carbon reduction targets and the transparent disclosure of sustainability metrics will remain a priority.
Public Sustainability Goals and Progress
Our sustainability goals establish targets for energy, GHG emissions, building certifications, water consumption and waste. In 2016, we achieved our first round of energy, emissions and water goals three years early, and we achieved our second emissions reduction target in 2019. By resetting company-wide goals, we seek to increase stakeholder awareness and endeavor to drive continuous year-over-year, like-for-like key performance indicator improvement. We have adopted goals with the following specific time frames, metrics, and targets below the noted baseline years (2022 is the most recent year for which complete and third-party assured data is available):

Sustainability & Impact Reporting
A notable part of our commitment to sustainable development and operations is our commitment to transparent reporting of sustainability performance indicators, as we recognize the importance of this information to investors, lenders and others in understanding how BXP assesses sustainability information and evaluates risks and opportunities. We publish an annual Sustainability & Impact Report that is aligned with the Global Reporting Initiative (GRI) Framework, United Nations Sustainable Development Goals and the SASB Framework. BXP’s Sustainability & Impact Report includes our strategy, key performance indicators, annual like-for-like comparisons and achievements. The report is available on our website at http://www.bxp.com under the heading “Commitment.” Our annual sustainability reports, including all of our energy, water and emissions metrics included therein, are assured by an independent, third-party assurance expert. The assurance expert performs an independent verification for certain of our performance indicators and issues an opinion, which is attached to each sustainability report, that opines on each sustainability report’s inclusiveness, materiality, sustainability context, completeness and reliability.
We have been an active participant in the green bond market since 2018, which provides access to sustainability-focused investors interested in the positive environmental externalities of our business activities. Since 2018, BPLP has issued an aggregate of $5.1 billion of green bonds in six separate offerings. The terms of the green bonds have restrictions that limit our allocation of the net proceeds to “eligible green projects.” We publish Green Bond Allocation Reports disclosing the full or partial allocation, as applicable, of net proceeds from the green bond offerings to eligible green projects. We have published five Green Bond Allocation Reports that have allocated more than $3.4 billion in net proceeds to eligible green projects, with the remaining net proceeds to be allocated to future eligible green projects pending final LEED certifications. The Green Bond Allocation Reports are available on our website at http://www.bxp.com under the heading “Commitment,” but are not incorporated by reference in this proxy statement or any other document we file with the SEC.

1.The number of shares of BXP common stock “beneficially owned” by each beneficial owner is determined under rules issued by the SEC. This information is not necessarily indicative of beneficial ownership for any other purpose. “Number of Shares Beneficially Owned” includes the number of shares of BXP common stock issuable to directors upon settlement of deferred stock units on or within 60 days after February 12, 2024. The “Number of Shares and Units Beneficially Owned” includes all shares included in the “Number of Shares Beneficially Owned” column plus the number of shares of BXP common stock for which common units and LTIP units may be redeemed (assuming, in the case of LTIP units, that they have first been converted into common units). Under the limited partnership agreement of the Operating Partnership, the holders of the common units and LTIP units (assuming conversion in full into common units, as applicable) have the right to

/Principal and Management Stockholders
redeem the units for cash or, at BXP's option, shares of BXP common stock, subject to certain conditions. Except as otherwise noted, each beneficial owner has sole voting and investment power over the shares and units. Holders of common units, LTIP units and deferred stock units are not entitled to vote such units on any of the matters presented at the 2024 annual meeting.
2.The total number of shares outstanding used in calculating this percentage assumes the conversion into shares of BXP common stock of all deferred stock units held by the beneficial owner and that no deferred stock units held by other beneficial owners are converted.
3.The total number of shares outstanding used in calculating this percentage assumes (a) that all common units and LTIP units (assuming conversion in full into common units, if applicable) are presented to the Operating Partnership for redemption and are acquired by BXP for shares of BXP common stock, (b) does not separately include outstanding common units held by BXP, as these common units are already reflected in the denominator by the inclusion of all outstanding shares of common stock, and (c) the conversion into shares of BXP common stock of all deferred stock units the receipt of which has not been deferred to a date later than 60 days after February 12, 2024.
4.Includes the number of shares of common stock and deferred stock units shown in the table below. Also includes, only under the “Number of Shares and Units Beneficially Owned” column, the number of common units and LTIP units shown in the table below. Excludes Unearned Performance Awards.

Compensation of Directors
At our 2022 annual meeting of stockholders, our stockholders approved the Boston Properties, Inc. Non-Employee Director Compensation Plan (the "Director Compensation Plan"), effective January 1, 2022. The Director Compensation Plan sets forth the cash and equity compensation that is paid to our non-employee directors in a specific, formulaic manner.
Directors who are also employees of BXP or any of its subsidiaries (i.e., Messrs. Thomas and Linde) receive no additional compensation for their services as directors.
Components of Director Compensation
Cash Retainers
Non-employee directors do not receive meeting fees for attending any meeting of our Board of Directors or a committee thereof. Instead, during 2023, we paid our non-employee directors the following cash retainers for Board and committee service under the Director Compensation Plan:
Role/Committee
Annual Cash Retainer(1)(2)
($)
Committee Chair Retainer(1)(2)
($)
Committee Member Retainer(1)(2)
($)
All Non-Employee Directors for Board Services85,000

Lead Independent Director(2)

Audit Committee20,00015,000
Compensation Committee15,00010,000
NCG Committee15,00010,000
Sustainability Committee15,00010,000
1.The sum of all cash retainers are payable in quarterly installments in arrears, subject to proration for periods of service less than a full quarter in length.
2.A retainer is only payable to the Chairman of the Board if the Board appoints an independent Chairman. Otherwise, a retainer is paid to the Lead Independent Director. The retainer payable to the Chairman or the Lead Independent Director is in addition to all other retainers to which the Chairman or the Lead Independent Director may be entitled, and the retainers payable to each committee chair are in addition to the retainers payable to all members of the committee.
Non-employee directors are also reimbursed for reasonable expenses incurred to attend Board of Directors and committee meetings.
Equity Compensation
The Director Compensation Plan provided for grants of equity to non-employee directors in 2023 as follows:
Annual Grant. Each continuing non-employee director received, on the fifth business day after the 2023 annual meeting of stockholders, an annual equity award with an aggregate value of $165,000.
Initial Grant. Any new non-employee director that is appointed to our Board of Directors other than at an annual meeting of stockholders would be entitled to receive, on the fifth business day after the appointment, an initial equity award with
62 BXP / 2024 Proxy Statement

Compensation of Directors/
an aggregate value of $165,000 (prorated based on the number of months from the date of appointment to the first anniversary of the Company's most recently held annual meeting of stockholders).
Annual and initial equity awards are made in the form of shares of restricted common stock or, if elected by the director, LTIP units (or a combination of both).
The actual number of shares of restricted common stock and LTIP units that we granted was determined by dividing the fixed value of the grant by the closing market price of our common stock on the NYSE on the grant date.
Annual and initial grants of LTIP units and restricted common stock vest 100% on the earlier of (1) the first anniversary of the grant date and (2) the date of the next annual meeting of stockholders.
Accordingly, on May 31, 2023, the fifth business day after our 2023 annual meeting of stockholders, the last reported sale price of a share of our common stock on the NYSE was $48.67, and we granted each of Mses. Ayotte, Einiger, Hoskins and Kipp and Messrs. Duncan, Klein, Lustig, Walton and West 3,390 LTIP units or shares of restricted common stock.
Deferred Compensation Program
In accordance with our Amended and Restated Rules and Conditions for Directors’ Deferred Compensation Program, non-employee directors may elect to defer all cash retainers otherwise payable to them and to receive the deferred cash compensation in the form of BXP common stock or in cash following cessation of service on our Board of Directors. Each director who elects to defer his or her cash retainers is credited with a number of deferred stock units determined by dividing the amount of the cash compensation deferred during each calendar quarter by the closing market price of our common stock on the NYSE on the last trading day of the quarter. Hypothetical dividends on the deferred stock units are “reinvested” in additional deferred stock units based on the closing market price of the common stock on the cash dividend payment date.
Directors may elect to receive payment of amounts in their accounts either in (x) a lump sum of shares of our common stock equal to the number of deferred stock units in a director’s account or (y) ten annual installments following the director’s cessation of service on our Board of Directors. In addition, non-employee directors who elect a deferred payout following their cessation of service may elect to change their notional investment from BXP common stock to a deemed investment in one or more measurement funds. The director may only make such an election after the director’s service on the Board ends, the effective date must be at least 180 days after the latest issuance date on which deferred stock units are credited to the director’s account, the election is irrevocable and the director may only elect to change the notional investment in 25% increments. Payment of a director’s account that has been changed to measurement funds will be made in cash instead of shares of our common stock. The measurement funds available to directors are the same as those available to our executives under our Nonqualified Deferred Compensation Plan. See “Compensation of Executive Officers—Nonqualified Deferred Compensation in 2023” on page 109.
Director Stock Ownership Guidelines
Our Board believes it is important to align the interests of our directors with those of our stockholders and that directors hold equity ownership positions in BXP. Accordingly, each non-employee director is expected to retain an aggregate number of shares of our common stock, deferred stock units (and related dividend equivalent rights) in the Company, and LTIP units and common units in the Operating Partnership, whether vested or not, equal to at least five (5) times the value of the then-current annual cash retainer paid to non-employee directors for their service on the Board, without respect to service on committees of the Board or as Lead Independent Director or Chairman, as applicable. Until the director complies with the ownership guidelines set forth above, he or she is expected to retain all equity awards granted by the Company or the Operating Partnership (less amounts sufficient to fund any taxes owed relating to such equity awards). The deferred stock units (and related dividend equivalent rights) in the Company and LTIP units and common units in the Operating Partnership shall be valued by reference to the market price of the number of shares of our common stock issuable upon the settlement or exchange of such units assuming that all conditions necessary for settlement or exchange have been met. For purposes of valuing shares of our common stock and other equity securities valued by reference to our common stock under these ownership guidelines, the market price of our common stock used to value such equity shall be the greater of (1) the market price on the date of purchase or grant of such equity or (2) the market price as of the date on which compliance with these ownership guidelines is measured.

Executive Summary
ConsiderationsDecisions & Results
è
Received ~89% stockholder support for BXP's executive compensation program for four consecutive years (2020-2023)
Maintained the same overall design, structure & components of BXP's executive compensation program for 2023
Exceeded 2023 goals and generated 2023 TSR of +11%, significantly improved from 2022 TSR
CEO's 2023 actual TDC was 2.8% greater than 2023 target TDC and 2.2% greater than 2022 actual TDC
Continued Commitment to BXP’s Executive Compensation Program
For 2023, the Committee retained the overall design, structure and components of BXP’s executive compensation program, reaffirming the Committee's commitment to align the interests of our NEOs with those of our stockholders. To achieve this objective, we grant a significant portion of our NEOs’ target total direct compensation in the form of long-term incentive (“LTI”) equity awards (i.e., 75% for our CEO), consisting of both performance-based and time-based equity awards. As BXP’s total stockholder return (“TSR”) fluctuates, the value of equity awards previously granted correspondingly fluctuates.
The Committee values our stockholders’ support of our executive compensation program, which informed the decision to maintain the same overall executive compensation program for 2023. This decision was reaffirmed in May 2023 when, for the fourth consecutive year, our stockholders expressed their support for our executive compensation program with more than 89% of the shares cast FOR our advisory Say-on-Pay proposal.
The 2023 Environment
Each year, when the Committee determines the target total direct compensation ("TDC") amounts and the goals against which each executive’s performance will be assessed for that year, the Committee evaluates the opportunities in front of the executive team. For 2023, the Committee conducted this evaluation in the context of the broader economy, supply and demand challenges for commercial office space, particularly with respect to demand from technology and life sciences companies, and the expected interest rate environment for 2023. In addition, the slowing economy combined with stubbornly high inflation affected our clients’ operations and long-term decision-making, which generally muted leasing activity in varying degrees depending on location and further exacerbated the uncertainty over the future performance of the office sector.
Despite these obstacles, our NEOs and other executive officers provided strong leadership; produced strong leasing results; further strengthened BXP's balance sheet through numerous financings and refinancings; allocated capital and made selective investments intended to enhance long-term growth and value; continued to execute our development pipeline; deepened our existing relationships with certain key institutional partners; and advanced our sustainability initiatives. The Committee believes our NEOs executed our overall strategy and produced strong operating results in 2023.
The overall design, structure and components of BXP's executive compensation program remain optimized to drive long-term performance. The Committee regularly reviews the executive compensation with a goal of ensuring that the performance goals and metrics are well-designed to incentivize short- and long-term operational achievements that deliver shareholder value (see "2024 MYLTIP Structure & Design”).

2023 Compensation Decisions and Highlights
2023 Employment Agreements
On February 28, 2023, BXP entered into a Second Amended and Restated Employment Agreement with Mr. Ritchey, 73, who has served as BXP's Senior Executive Vice President since January 2016 and has been employed by BXP since 1980. Under his new employment agreement, Mr. Ritchey agreed to continue to serve as BXP's Senior Executive Vice President through December 31, 2023 and, on average, devote at least approximately 50% of his business time to BXP’s business and affairs. In consideration for such service, the agreement (1) set Mr. Ritchey's base salary at $750,000 for 2023, which represented no change from 2022; (2) established a 2023 target cash bonus opportunity of $1,650,000, with the actual earned amount to be determined by the Committee after assessing Mr. Ritchey's performance against established leasing, business and individual goals; (3) eliminated any LTI equity incentive opportunity for 2023 performance (which would have been granted in early 2024) and (4) eliminated Mr. Ritchey’s right to receive tax gross-up payments. Mr. Ritchey’s 2022 target TDC was $6.8 million. Under his new employment agreement, Mr. Ritchey's 2023 target TDC was $2.4 million, representing a decrease of approximately 65% from 2022. Mr. Ritchey’s total 2023 compensation as calculated in accordance with Item 402(c) of Regulation S-K and presented in the Summary Compensation Table on page 102 includes $4.1 million of LTI equity that was granted to Mr. Ritchey in early 2023 for 2022 performance. However, Mr. Ritchey did not receive any LTI equity awards for 2023 performance. For this reason, the Committee does not expect Mr. Ritchey to be an NEO for 2024.
BXP / 2024 Proxy Statement 69

/Compensation Discussion and Analysis
In determining the terms of Mr. Ritchey's 2023 employment agreement, the Committee balanced the anticipated reduction in BXP workload with, among other things, the material benefits that inure to BXP from Mr. Ritchey's continued involvement in our business. These include the positive impact of his direct involvement in certain of BXP’s key transactions in 2023 (see Mr. Ritchey’s NEO Scorecard on page 87 for more information), his instrumental role in the development of our leadership teams in our two newest markets – Los Angeles and Seattle, the importance of his continued mentorship of many other current and future BXP leaders, and his positive impact on BXP's overall culture. Based on the foregoing, Mr. Ritchey's 2023 compensation arrangements did not include him in the 2023 annual cash incentive plan (“AIP”) to which all other NEOs were subject and instead focused on a set of pre-established leasing, business and individual goals. As a result, throughout this CD&A, unless otherwise noted, Mr. Ritchey is not included in references to our NEOs, collectively, or "NEOs as a group" for information and data linked to or that includes the 2023 AIP and LTI equity grants for 2023 performance (granted in early 2024). See “Compensation of Executive Officers—Employment Agreements—Summary of Mr. Ritchey’s Employment Agreement.”
In 2023, we also entered into an Amended and Restated Employment Agreement with Mr. Thomas, effective July 1, 2023, pursuant to which he agreed to continue to serve as BXP's Chief Executive Officer through December 31, 2026. The Amended and Restated Employment Agreement did not change Mr. Thomas’ base salary, target cash bonus or target total compensation for 2023. Consistent with BXP's policy not to provide new rights to receive tax gross-up payments, Mr. Thomas is not entitled to receive any such payments. See “Compensation of Executive Officers—Employment Agreements—Summary of Mr. Thomas' Employment Agreement.”

2023 NEO Compensation Decisions
2023 Executive Compensation Framework
In 2023, the Committee maintained the following framework:
the percentage of target TDC that is variable: ~93% of our CEO’s target TDC is “at risk,” and more than 90% of our NEOs’ target TDC is “at risk”
~75% of our CEO’s target TDC is paid in equity
~68% of our NEOs’ target TDC is paid in equity
the overall design, structure and categories of the AIP, including the same three categories - (1) diluted FFO per share, (2) leasing and (3) business & individual goals - upon which each NEO's bonus is determined formulaically, ranging from zero to a max opportunity of 150% of target
the LTI equity allocations: 55% performance-based and 45% time-based equity for our CEO; 50% performance-based and 50% time-based equity for all other NEOs
the design and structure of the performance-based MYLTIP program, including the same, two equally weighted components with payout opportunities based on BXP’s relative and absolute TSR performance over a three-year performance period.
2023 AIP Payouts
In January 2024, the Committee determined and approved bonus payments as provided under the 2023 AIP as follows:
BXP’s diluted FFO per share for 2023 resulted in a payout of 124% of each NEO’s target for that category
for all executives subject to the 2023 AIP, earned short-term leasing payouts ranging from 0% to 137% of target and earned total leasing payouts ranging from 53% to 146% of target, in each case, depending on regional leasing results
for the NEOs specifically, earned short-term leasing payouts ranging from 76% to 90% of target and earned total leasing payouts ranging from 114% to 120% of target
for all executives subject to the 2023 AIP, earned payouts for the business & individual goals category ranging from 80% to 150% of target
for the NEOs specifically, earned payouts ranging from 100% to 150% of target for this category
Our NEOs received total cash bonuses that ranged between 104.0% to 127.8% of their respective target bonus amounts.
2023 Long-Term Incentive Equity Decisions
For 2023, the Committee awarded the NEOs 100% of their target LTI equity amounts (granted on February 6, 2024). The ultimate value of these awards will depend on BXP’s performance over the multi-year performance and vesting periods. See “2023 Executive Compensation —LTI Equity Compensation” for more information regarding these awards.
BXP / 2024 Proxy Statement 71

/Compensation Discussion and Analysis
Our Executive Compensation Program
Executive Compensation Philosophy
In 2023, we maintained the overall structure, design and components of the executive compensation program to:
attract and retain talented and experienced executives in the commercial real estate markets in which we operate,
provide target total compensation opportunities to be competitive with companies in our benchmarking peer group, considering the skill sets required to implement our strategy and the market for such talent (see “—Determining Executive Compensation—Compensation Advisor’s Role & Benchmarking Peer Group—Benchmarking Peer Group”),
align our NEOs’ compensation with the Company’s strategy and business objectives for creating long-term value for our stockholders without encouraging unnecessary or excessive risk-taking,
provide NEOs incentives to achieve key corporate and regional goals by linking formulaically annual cash incentive awards to the achievement of those goals, as well as goals tailored for each individual, and
provide a majority of target total direct compensation opportunity for the NEOs in the form of LTI equity awards, a majority of which are performance-based (55% for our CEO) and the value of which is dependent on BXP’s TSR over three years, both on a relative basis compared to the Company’s most directly comparable peers and on an absolute basis.
Components of Executive Compensation
ComponentWhy We Pay It
Base SalaryProvide a fixed, competitive level of cash compensation that reflects the NEO’s leadership role, job function and the market rate for the executive’s experience and responsibilities
Annual Cash Incentive
Reward NEOs for the achievement of annual financial, operational and strategic goals that drive stockholder value, thereby aligning our NEOs’ interests with those of our stockholders
Annual cash bonuses for each NEO are linked to performance against goals in three weighted categories, and each NEO has target and maximum bonus opportunities that allow for payouts ranging from 0 to 150% of target
Performance-Based Equity (MYLTIP)
Align the interests of our NEOs with those of our stockholders
Motivate, retain and reward NEOs to achieve multi-year, strategic business objectives that are intended to drive company and executive outperformance
Create a direct link between executive pay and relative and absolute TSR performance
Enhance executive officer retention with 100% vesting after completion of a three-year performance period (i.e., “cliff vesting”), with one additional year of post-vesting transfer restrictions
Time-Based Equity
Align the interests of our NEOs with those of our stockholders
Motivate, retain and reward NEOs to achieve multi-year, strategic business objectives that drive absolute TSR outperformance
Create a direct link between executive pay and absolute TSR performance
Enhance executive officer retention with time-based, multi-year vesting schedules for equity incentive awards

2023 Say-On-Pay Vote & Investor Outreach
Say-on-Pay Vote
At our 2023 annual meeting of stockholders, more than 89% of the votes cast supported our “Say-on-Pay” advisory vote. The 2023 compensation year was our fourth year utilizing a more objective, formulaic annual bonus plan, which our Committee implemented beginning in 2020 based on investor feedback. Stockholder support for our executive compensation program has been consistent since that change, as evidenced by an average of more than 89% in support for our Say-on-Pay advisory proposals over the last four years. The continued support of our stockholders is a direct result of our commitment to actively engage with our investors on all matters, including executive compensation, and our responsiveness to the feedback received.
Investor Outreach & Feedback
We are firmly committed to learning investors’ perspectives and believe that proactive engagement is an effective means to solicit and receive valuable feedback. This feedback is essential as we set our strategy and refine our policies and practices. We conduct outreach throughout the year to ensure that management and the Board understand the issues of importance to our investors and address them appropriately. The Board regularly reviews stockholder feedback, which informs Board discussions on various topics, including investment philosophy and outlook, market fundamentals and expectations, and our approaches to executive compensation, Board composition, risk oversight, environmental and social initiatives, human capital management and corporate governance generally.
We believe our engagement efforts have been meaningful for our investors and us, and we are pleased that in 2023 Institutional Investor ranked us #3 among all REITs in four categories (as voted by buy-side analysts): Best Company Board, Best ESG Program, Best IR Program and Best Analyst Days, and #1 among office REITs in these categories.
In 2023, we engaged directly and frequently with our investors in various forums and through different media (including in-person and virtual meetings). We allocate time each quarter following our earnings release and public conference call to speak with our investors regarding any additional questions on topics of interests. In addition to discussions in the ordinary course of business, BXP successfully hosted (1) non-deal roadshows in Chicago, Toronto, Montreal and New York City meeting with more than 30 potential and existing investors, and (2) its second annual ESG Virtual Investor Call, which more than 170 individuals viewed.
In addition, we participated in (1) numerous real estate conferences throughout the year, including the 2023 Citi Global Property CEO Conference, BMO's Real Estate Conference, Nareit REITweek Investor Conference, Bank of America 2023 Global Real Estate Conference, 2023 Evercore ISI Conference and the 2023 Nareit REITworld Conference, and (2) two conferences for non-REIT-dedicated investors: the BofA Financials Conference and Barclays Global Financial Conference. We held one-on-one meetings with various current and potential investors at these conferences, from which we gained helpful insight into matters of importance to the investors.
In the aggregate, in 2023, we engaged directly with representatives of more than 300 firms, including approximately 133 U.S. and international institutional investors who owned, in the aggregate, approximately 63% of the total number of outstanding shares of BXP common stock as of December 31, 2023.
2023 Executive Compensation
2023 Annual Target Compensation
In January of each year, the Committee establishes a target amount for TDC for each NEO by considering competitive benchmarking data, position, level of responsibility and experience, and, for our EVPs, our CEO’s and President's recommendations, and for our President, our CEO's recommendations. Targets are reviewed annually and adjusted if the Committee determines that it is appropriate to do so. The Committee may also adjust target compensation to reflect changes in or new responsibilities for a particular executive. In considering the appropriate annual target amounts for each component for 2023, the Committee considered the challenging economic conditions globally, nationally and specific to the commercial real estate industry (i.e., high inflation and interest rates, remote work headwinds, etc.), as well as the specific challenges our NEOs were expected to face in 2023.
74 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
For 2023, the Committee remained committed to the established executive compensation framework and did not change its overall design, structure or components. As a result, the Committee (1) maintained identical target cash bonus amounts for each NEO for 2023 for the second consecutive year and (2) approved increases to the NEOs' base salaries (2.7% for our CEO and 2.6% for the NEOs as a group, including Mr. Ritchey) and target LTI equity awards (5.3% for our CEO and 6.3% for the NEOs as a group, excluding Mr. Ritchey). As noted above, Mr. Ritchey's employment agreement did not change his base salary for 2023, and provided that he would not be entitled to receive LTI equity for 2023.
The target TDC for 2023 for each NEO was as follows:

Variable or “at-risk” pay, consisting of annual cash bonuses and LTI equity awards, constitutes the vast majority of our executive compensation. Having a significant portion of our executives’ compensation at risk more closely aligns their interests with our long-term interests and those of our stockholders. For our CEO and NEOs as a group, variable pay for 2023 was approximately 93% and more than 90%, respectively, of target TDC. This emphasis on variable pay allows the Committee to reward good performance and penalize poor performance. The following graphics illustrate the mix between fixed pay (base salary) and variable pay incentives (short-term incentives in the form of cash bonuses and long-term incentives in the form of both time-based and performance-based LTI equity awards) for our CEO and the NEOs as a group, in each case, based on 2023 target compensation levels.

Base Salary
The Committee determines the base salary for each NEO. It is intended to provide a fixed level of compensation that reflects the NEO’s leadership role and the relative market rate for similarly situated executives in the NEO’s position. The Committee determines whether to adjust base salaries based on various factors, including benchmark versus peers and changes in individual duties and responsibilities. Any increases to base salaries are generally determined in January of the compensation year and become effective in February.

2023 Annual Incentive Plan (AIP)
Program Design and Structure
In January 2020, based mainly on feedback received from our investors in 2019, the Committee established a new, more formulaic AIP under which annual cash bonuses payable to our executive officers are directly linked to the achievement of specific, pre-established goals. We continue to use the same AIP structure except for small shifts in weighting between categories and calculations in past years to more closely link each executive’s performance to his or her goals and incentivize executive performance.
Bonus Opportunity
Under the 2023 AIP, each NEO had a target bonus opportunity expressed in a fixed dollar amount. Actual earned amounts under the plan may range from zero (0) to 150% of target, depending on performance versus the annual goals in each category, with payout interpolated for performance between Threshold and Maximum.

2023 AIP Categories
We use a “scorecard” approach for our bonus determinations. This approach is intended to reflect a comprehensive analysis by the Committee of corporate, regional and individual performance based on performance in three categories: (1) diluted FFO per Share, (2) Leasing and (3) Business & Individual goals.
Diluted FFO per Share. The Committee selected diluted FFO per share as a key financial metric for the 2023 AIP because it is the earnings metric most commonly used by investors and analysts to evaluate the performance of REITs, both on an absolute and relative basis. As such, the Committee considers this to be an important, company-wide performance metric that is objective, drives near-term business strategies and ensures alignment of the interests of our executives with those of our stockholders. For 2023, the target for diluted FFO per share was determined using the midpoint of BXP’s 2023 diluted FFO per share guidance, which was publicly announced to our investors in late
76 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
January 2023. Each year, when the Committee reviews performance results to determine earned payouts under the AIP, actual diluted FFO per share is adjusted in accordance with the terms of the AIP for acquisitions, dispositions, early debt redemption charges, and similar transactions and circumstances (in the discretion of the Committee) that can not be predicted at the time the Company provides FFO per share guidance to investors and thus are not included therein.
Leasing. The Committee selected this category because it is an objective measure fundamental to the Company’s short-term and long-term success. It links corporate, regional and individual performance by formula to the amounts paid. The Committee established specific leasing goals, starting at the property level, rolling up by region and then aggregating to corporate leasing goals, as the second component. The leasing goals were then categorized as short-term and total to encourage the executives to focus on current addressable vacancies and near-term roll-over and avoid scenarios in which leasing goals are met solely due to unexpected early renewals. The leasing goals are measured at the regional level for Mr. Koop and the other regional EVPs and at the corporate level for our CEO, President and CFO.
Business & Individual Goals. Business goals include milestone-oriented objectives related to acquisitions, dispositions, delivering development and construction projects on time and budget, achieving the desired returns on investments, securing entitlements for future development projects, launching new developments, the opportunistic use of joint ventures, and the management of capital expenditures and general and administrative expense. Business goals are based on regional priorities for Mr. Koop and the other regional EVPs. For the CEO and President, business goals include a relevant subset of those regional goals and goals related to overall corporate strategy and executive management. The CFO’s business goals relate to balance sheet management, capital raising, and other Finance Department priorities.
Individual goals include leadership and professional development goals, diversity initiatives, succession planning and sustainability priorities for each executive. The Committee considers performance outcomes against Business & Individual goals and objectives, as well as the context in which they were achieved (e.g., degree of difficulty, importance to BXP, headwinds and tailwinds during the year and other similar factors).
One of the Committee’s primary objectives when establishing Business & Individual goals each year, including in 2023, is to set annual goals that meaningfully advance the Company’s strategy for sustainable, long-term growth and value creation despite the short-term window for assessing performance against these goals. In some cases, it is not possible to assess an executive's performance against certain Business & Individual goals based on quantitative outcomes. In addition, the relative importance of some goals may be greater in one year than in another, depending on the circumstances when the Committee establishes the goals.

2023 AIP Weightings
As part of the Committee’s annual executive compensation process, in January 2023, the Committee reviewed and reassessed the AIP, including its categories and weightings. Based on its review of the AIP, the Committee concluded that the categories and weightings were appropriate. For the 2023 AIP, the performance measurement categories and weighting of each category were as follows:

1.Includes five "reach" leasing goals for which Messrs. Thomas, Linde, LaBelle and Koop had the opportunity to earn a positive adjustment to their payout percentages under the leasing category by up to ten percentage points if achieved.
2023 NEO Scorecards
Each year, with input from the CEO and President, the Committee establishes the categories (i.e., FFO per share, leasing and business & individual goals), the weightings for each category and the goals within each category under the AIP with the objective of directly linking each executive’s performance against the goals to the amount of the annual cash bonuses paid to such executive. Since the adoption of the Company’s more formulaic bonus plan in 2020, the Committee has generally used the same process to ensure that the goals are sufficiently rigorous and motivate our executives to meaningfully advance BXP’s business strategies, regardless of the economic conditions under which the Company is then operating.
As explained above, the target for diluted FFO per share is set using the midpoint of BXP’s diluted FFO per share guidance that is publicly announced to investors, typically in late January each year. Each year, the primary drivers of this guidance are expected revenue from contractual leases, speculative leasing projections that would lead to additional GAAP revenue during the year, the expected delivery of a property or properties under development, and projected operating expenses for our properties, general and administrative expense and interest expense.
In January 2023, when the Committee set the 2023 target for diluted FFO per share, the trajectory of the U.S. economy was uncertain. At the time, the rate of inflation was slowing, but remained generationally high, and interest rates continued to remain elevated. Against this economic backdrop, the Committee set the target for diluted FFO per share of $7.13, the midpoint of the diluted FFO per share guidance for 2023, which represented a projected 5.3% decrease in diluted FFO per share compared to actual 2022 diluted FFO per share. The primary driver for the projected decline was the significant increase in the cost of capital due to the aggregate 425-basis point increase in interest rates announced by the Federal Reserve throughout 2022, with additional increases expected throughout 2023. Given the Company’s outstanding floating rate debt and the need to refinance fixed rate debt upon maturity, this dramatic increase in interest rates negatively impacted the Company’s projected net interest expense for 2023. For the foregoing reasons, the Committee believed the 2023 target diluted FFO of $7.13 per share was rigorous and appropriate.
78 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
The quantitative leasing goals under the AIP differ from year to year – sometimes materially – based on leasing activity the Committee determines is reasonably possible. The process of setting the leasing goals each year necessarily begins by analyzing the amount of currently vacant space in the Company’s portfolio, the amount of space covered by leases with near-term maturities in 2023 and the amount of space covered by leases with terms that expire more than twelve (12) months later (2024 and beyond). The Committee also considers the potential difficulty in successfully leasing the space. This includes factoring potential leases that are already subject to a letter of intent or the terms of which are under negotiation at the time the goals are established, and it also considers the probability of signing early lease renewals more than one year prior to lease maturity. For example, for 2023, there was less square footage covered by expiring leases that could be included in the leasing goals compared to 2022. During more robust economic conditions, BXP may also have a leasing target for new development starts that could have a material impact on the overall leasing volumes. As a point of reference, the 2022 leasing goals included new development starts that totaled approximately 800,000 square feet of leasing, however, similar opportunities were not available in 2023.
In addition, the Committee factors the overall health of the economies in the regions in which the Company operates and the expected impact those conditions will have on leasing demand. For example, at the beginning of 2023, all three of our West Coast regions were experiencing a supply of office space that far exceeded the demand in those regions. Current and prospective clients in these markets were dominated by technology and life science companies that were laying-off employees and facing materially greater interest rates that caused them to defer major leasing decisions. The Committee then considers the totality of these factors when setting the threshold and maximum payout opportunities. The Committee believes the consistent process by which it sets the leasing goals each year helps ensure that they are rigorous.
As a result of these considerations, the Committee established the following 2023 targets for short-term and total leasing that were less than actual short-term and total leasing achieved in 2022: 3.2 million square feet and 3.4 million square feet, respectively. The Committee determined these leasing targets were appropriately rigorous in light of the leasing opportunities available in 2023 in our operating asset portfolio and our development pipeline, the anticipated impacts of the slowing economy on our clients' operations and long-term decision-making, and the weakening supply and demand fundamentals in our markets.
For the 2023 leasing category, based on preliminary discussions with clients leading into 2023, the Committee added five additional leasing opportunities, the execution of which was highly uncertain at the beginning of the year. These opportunities were large, unique and binary in nature — i.e., they would either be completed or not, leading to an all-or-nothing payout for each additional lease. Therefore, such leasing opportunities were not included in management's annual leasing goals because the successful (or unsuccessful) execution of any one of the leases could improperly skew the results of the leasing goals. Instead, the Committee designated these five leasing opportunities as "reach" leasing goals for which each of the corporate executives (Messrs. Thomas, Linde and LaBelle) and Mr. Koop had the opportunity to earn a positive adjustment to his leasing category payout percentage if achieved, prorated for each executive (by six percentage points for Mr. Koop related to three leasing opportunities in the Boston region, and by ten percentage points for the corporate executives related to the three Boston region opportunities, one in Los Angeles and one in Washington, DC). Only one of these "reach" leasing transactions was completed in 2023 - a 467,000 square foot lease extension in Los Angeles.
Set forth in the following tables is a summary of each NEO’s performance measures and weightings, with specific threshold, target and maximum payout opportunities for each of the diluted FFO per share and leasing performance categories, and the principal Business & Individual goals, along with each NEO’s performance results for 2023. The Committee considers absolute and/or relative performance outcomes against Business & Individual goals, as well as the context in which they were achieved (e.g., degree of difficulty, importance to BXP, headwinds and tailwinds during the year and other similar factors), but no specific weightings are ascribed to each of the Business & Individual goals. The following scorecards include only the most material Business & Individual goals for each NEO that the Committee considered in assessing 2023 performance.

actively engaged with new potential investors and existing partners to generate commercial opportunities for BXP. In particular, Mr. Thomas had direct involvement with many of BXP's key partners, which led to:
1.the opportunistic acquisition of joint venture interests from two institutional partners in three assets for an aggregate cash purchase price of $48 million; and
2.the significant ~$750 million private equity capital raise in an otherwise constrained capital markets environment, which also further strengthened BXP's existing partnership with the institutional investor.
successfully executed reorganization and leadership transition for the West Coast regions with the appointment of Mr. Rod Diehl as Executive Vice President, West Coast Regions, to succeed Mr. Pester upon his retirement in early 2024.
successfully advanced BXP’s sustainability and diversity efforts and maintained BXP’s leadership position in sustainability in the real estate industry.
In addition, the Committee noted that Institutional Investor ranked Mr. Thomas as #1 Best CEO among all mid-cap REITs.
After assessing Mr. Thomas' performance against his Business & Individual goals and the relative importance of the goals, the Committee determined that Mr. Thomas earned 120% of the target for the Business & Individual goals category.

Compensation Discussion and Analysis/
Assessment
In assessing Mr. LaBelle’s performance against his Business & Individual goals, the Committee noted in particular that Mr. LaBelle not only met the capital raising goal to raise an aggregate of approximately $3.85 billion in 2023, but exceeded the goal by raising an aggregate of approximately $4.5 billion in that timeframe (our share totaled approximately $4.0 billion). Mr. LaBelle oversaw the completion of:
$2.3 billion of unsecured financings: a $1.2 billion unsecured term loan facility, a $750 million “green bond” offering and an increase in total commitment under the revolving credit facility by $315 million to $1.815 billion by leveraging banking relationships to add three new lenders to the facility;
$1.0 billion (our share) of secured financings: a $600 million mortgage loan collateralized by a three-building portfolio located in Cambridge, Massachusetts, and five property-level refinancings totaling approximately $929 million in aggregate principal amount (of which our share was approximately $423 million); and
~$750 million of private equity investment from an institutional partner for 45% interests in two development/redevelopment projects in Kendall Square in Cambridge, Massachusetts.
In addition, Mr. LaBelle furthered BXP’s short-term and long-term value creation objectives by, among other things, creatively structuring and effectuating strategic financing transactions for five assets, two of which facilitated the subsequent signing of long-term lease renewals with anchor clients. These transactions included (1) two joint venture partnerships in which BXP played significant roles in the capital restructurings of each, resulting in BXP providing mezzanine financing to the property owners (500 North Capitol and Metropolitan Square in Washington, DC), (2) the acquisitions of an institutional partner's interests in two assets (Santa Monica Business Park in Santa Monica, California, and 360 Park Avenue in New York City, New York), following which, BXP executed a long-term lease with an anchor client at Santa Monica Business Park, and (3) the acquisition of an institutional partner's interest in 901 New York Avenue (consummated in early January 2024), following which, BXP executed a long-term lease with an anchor client.
In addition to Mr. LaBelle’s management of BXP’s balance sheet, he provided strong leadership and advanced critical initiatives in his direct management of the Finance, Accounting, Tax and Investor Relations Departments. The Committee also noted that Institutional Investor ranked Mr. LaBelle as the #1 Best CFO among all mid-cap REITs, and he was instrumental to BXP’s rankings as #3 Best IR Program, Best Analyst Days and Best ESG Program among all REITs and #1 among office REITs in those three categories, as voted by buy-side analysts.
After assessing Mr. LaBelle’s performance against his Business & Individual goals and the relative importance of the goals, including the business critical execution of BXP's capital raising plan in 2023 despite extremely challenged debt and capital market conditions, the Committee determined that Mr. LaBelle earned 150% of the target for this category.

Raymond A. Ritchey
In accordance with his employment agreement, the Committee established leasing, business and individual goals for Mr. Ritchey against which they assessed his performance for 2023. Mr. Ritchey's leasing goals were measured against regional targets for the Los Angeles, Seattle and Washington, DC regions, his business goals were based on regional priorities for those three regions and his individual goals were focused primarily on leadership and organizational objectives. Under the terms of his employment agreement, Mr. Ritchey's 2023 annual cash bonus included additional upside opportunity for any new business he personally generated for the benefit of BXP; Mr. Ritchey did not receive any additional cash bonus related thereto.
Set forth below are the material goals that the Committee considered in assessing Mr. Ritchey's 2023 performance.

/Compensation Discussion and Analysis
Assessment
In assessing Mr. Ritchey’s performance against his leasing, business and individual goals, the Committee concluded that he achieved the majority of the goals established for him, and those that were not met were primarily due to the particularly challenged capital market conditions on the West Coast that made generating new opportunities and transacting in those regions unrealistic. In addition, the Committee's evaluation of Mr. Ritchey's performance included consideration of Mr. Ritchey's meaningful contributions to our overall performance and advancement of our long-term strategy, as well as his integral role in the development of talent at all levels of our organization, the promotion of our culture of excellence, and enhancing BXP's brand.
In particular, the Committee noted that Mr. Ritchey:
exceeded the target total leasing square footage for each of the Washington, DC, Los Angeles and Seattle regions by executing a total of approximately 979,000 square feet of leases. In addition, Mr. Ritchey actively contributed to the successful execution of the long-term, approximately 467,000 square foot, multi-building lease extension at Santa Monica Business Park
strategically utilized long-established relationships with clients and brokers and effectively participated in leasing negotiations to (1) achieve the leasing goals and (2) further enhance BXP's presence in the Seattle and Washington, DC markets
leveraged his relationships and local industry stature in the Washington, DC region to, among other things, facilitate the capital restructuring of Metropolitan Square and BXP's acquisition of a 50% joint venture interest in a property in Virginia
had direct involvement in ensuring the successful reorganization and leadership transition on the West Coast with the appointments of Mr. Rod Diehl as Executive Vice President, West Coast Regions, and regional leaders in the Los Angeles and Seattle regions
continued his strong mentorship and development of specified executives and regional leaders that resulted in objective advancements of his mentees' leadership, negotiating and execution skills in complex transactions
After assessing Mr. Ritchey’s performance against his Leasing and Business and Individual goals, and the relative importance of the goals, the Committee determined that Mr. Ritchey earned 120% of the target opportunity set for him.

LTI Equity Compensation
The equity component of our NEOs’ compensation is granted in the form of LTI equity awards consisting of a mix of time-based and performance-based awards. The ultimate value, if any, of these awards is driven significantly by our TSR.
88 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
Time-Based Equity Awards
The time-based LTI equity awards granted to the NEOs for 2023 performance consisted of LTIP units or restricted shares of our common stock that generally vest in equal, annual installments over four years (25% per year), subject to acceleration in certain circumstances (e.g., retirement, death or disability, and certain qualifying terminations following a change in control). See “Compensation of Executive Officers—Potential Payments Upon Termination or Change in Control—Retirement Eligibility Provisions for LTI Equity Awards.
Performance-Based Equity Awards – Multi-Year Long-Term Incentive Program (MYLTIP)
The performance-based portion of LTI equity awards is granted under our Multi-Year Long-Term Incentive Program, or “MYLTIP.” We grant MYLTIP awards to provide incentives for long-term TSR performance over a multi-year period. The MYLTIP awards link the ultimate payouts directly by formula to our absolute and relative TSR over a three-year measurement period.

The 2023 MYLTIP awards were denominated in a fixed number of LTIP units. The number of LTIP units initially issued to each award recipient on the grant date is the maximum number of units that the award recipient may earn under the 2023 MYLTIP (it is not a projection of the number of units the executive will actually earn). The 2023 MYLTIP awards have a three-year performance period (February 7, 2023 to February 6, 2026) and an additional one-year, post-vesting holding period (see “—2023 MYLTIP Structure & Design—Other Features of 2023 MYLTIP”). Following the completion of the three-year performance period, the Committee will determine the final payout based on computations from our independent valuation consultant for this plan. If the number of units initially awarded exceeds the number of units ultimately earned, then the award recipient must forfeit the excess.
BXP / 2024 Proxy Statement 89

/Compensation Discussion and Analysis
Therefore, while the award of 2023 MYLTIP units was partially in recognition of performance in 2022, award recipients must continue to perform over the three-year term of the 2023 MYLTIP to earn and vest in any of the MYLTIP units and hold the units for an additional year. As a result, recipients can not monetize the awards until at least four years after the grant date.
2023 MYLTIP Structure & Design
On January 25, 2023, the Committee approved LTI equity awards to NEOs for 2022 performance as a mix of time-based, full-value equity awards and performance-based MYLTIP awards. The structure and design of the 2023 MYLTIP are the same as those for the 2022 MYLTIP, except JBG Smith Properties was not included in the 2023 custom peer group index (the “Custom Index”) used to compare BXP's TSR performance against because it publicly announced a strategic shift to change the composition of its portfolio to majority multifamily. Therefore, the Committee concluded that including JBG Smith Properties in the Custom Index was no longer appropriate.
The 2023 performance-based MYLTIP consists of two equally weighted components, each providing a payout opportunity ranging from zero to 200% of a target number of LTIP units based on BXP’s relative and absolute TSR performance over a three-year performance period.
Relative TSR Component
One-half (50%) of the 2023 MYLTIP grant value was awarded in the form of LTIP units that can be earned based on BXP’s three-year, annualized TSR (“rTSR”) compared to the Custom Index as follows:
BXP Annualized TSR Relative to IndexPercentage of Target MYLTIP Units that are Earned
>= +1,000 basis points200%
0 basis points100%
<= -1,000 basis pointsZero
The payout for performance between levels outlined in the table above will be interpolated on a straight-line basis.
For purposes of measuring relative performance, the 2023 MYLTIP awards provide that BXP’s TSR shall be compared to the TSR of the Custom Index consisting of the following seven (7) office REITs:
Custom Index
Douglas Emmett, Inc.Kilroy Realty CorporationVornado Realty Trust
Empire State Realty TrustParamount Group, Inc.
Hudson Pacific Properties, Inc.SL Green Realty Corp.
The purpose of using a peer group is to provide a mechanism for comparing our relative performance against competitors; however, the Company does not have a directly comparable peer in the public market and often competes with larger, privately-capitalized companies for which performance data is not readily available, if at all. We selected the Custom Index to include only office REITs that are most similar to the Company in terms of asset type, asset quality, and having full-scale operations in one or more of the US gateway markets in which the Company operates.
For determining the TSR of the Custom Index, the weighting ascribed to each company in the Custom Index was fixed as of the grant date based on its relative market capitalization at that time.
90 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
Absolute TSR Component
The remaining one-half (50%) of the 2023 MYLTIP grant value was awarded in the form of LTIP units that can be earned based on BXP’s non-annualized, cumulative absolute TSR (“aTSR”) during the three-year performance period as follows:
BXP Cumulative aTSRPercentage of Target MYLTIP Units that are Earned
>= +60%200%
+10%100%
<= -40%Zero
The payout for performance between levels outlined in the table above will be interpolated on a straight-line basis.
The Committee added the aTSR component during its re-design of the MYLTIP in 2020, in part, to limit the scenarios in which our investors may suffer losses due to a decline in absolute TSR while our NEOs realize above-target payouts for relative TSR outperformance. As a result, BXP performance above the maximum goal under the rTSR component does not automatically result in a payout equal to the maximum 200% of target because the total payout would be offset if performance is below target under the aTSR component. The Committee concluded that this “offsetting” feature helps align our NEOs’ interests with our stockholders while providing incentive to outperform our peers.
Other Features of 2023 MYLTIP
Distributions. During the three-year performance period, holders of 2023 MYLTIP Units are not entitled to receive full distributions on the 2023 MYLTIP Units. Instead, to support the units’ characterization as profits interests for tax purposes, the holders of the units are entitled to receive only a partial distribution on each unit equal to 10% of the dividend payable on a share of BXP common stock. In addition, BXP will make a “catch-up” cash payment on the 2023 MYLTIP Units that are ultimately earned (if any) in an amount equal to the regular and special dividends, if any, declared during the performance period on BXP common stock, less the distributions paid to holders of 2023 MYLTIP Units during the performance period on all of the awarded 2023 MYLTIP Units.
Post-vesting Transfer Restrictions. Subject to the provisions on “Qualified Retirement” and the other terms of the award agreement, after the three-year performance period, all earned 2023 MYLTIP Units shall be deemed “vested.” Still, they may not be converted, redeemed, sold or otherwise transferred for one additional year after the end of the performance measurement period. Therefore, 100% of earned awards, if any, shall vest as of February 6, 2026, but may not be monetized until February 6, 2027.
2024 MYLTIP Structure & Design
In late 2023, the Committee, with the assistance of FW Cook, undertook a comprehensive review of the MYLTIP plan design to assess, among other things, the effectiveness of the plan's primary objectives of aligning the interests of our NEOs with those of our stockholders and motivating, retaining and rewarding our NEOs by directly linking executive pay with long-term performance. In its review, the Committee considered the appropriate metrics on which it should assess long-term performance, as well as the metrics utilized by BXP's benchmarking peer group against which the Company’s pay and compensation practices are assessed. After consideration, the Committee modified the design of the 2024 MYLTIP to add a new, third component (the "Leverage Component") that will measure performance against a target for the average of a non-GAAP leverage ratio – BXP’s Share of Net Debt to BXP’s Share of EBITDAre – cash (Annualized) (the average of such ratio, the "Average Leverage Ratio"), which is a non-GAAP financial measure. The 2024 MYLTIP now consists of three components, with the Leverage Component representing 20% of the target grant date fair value, and each of the Relative TSR Component and Absolute TSR Component representing 40% of the target grant date fair value. The Committee believes the addition of the Leverage Component to the design of the MYLTIP provides a balance between the market-based absolute and relative TSR measures currently used and a financial operating measure that supports BXP's strategic objective of managing leverage.
BXP / 2024 Proxy Statement 91

/Compensation Discussion and Analysis
The Average Leverage Ratio will be calculated as of the end of the three-year performance period for the 2024 MYLTIP and will equal the average of (A) and (B) below:
(A)BXP's Share of Net Debt as of September 30, 2026
BXP's Share of EBITDAre – cash for the quarter ended September 30, 2026 x 4
(B)BXP's Share of Net Debt as of December 31, 2026
BXP's Share of EBITDAre – cash for the quarter ended December 31, 2026 x 4
To calculate the Leverage Component at the end of the performance period, we use the same calculations of BXP’s Share, EBITDAre, EBITDAre – cash, BXP’s Share of EBITDAre – cash (Annualized) and Net Debt as set forth in our Supplemental Operating and Financial Data reports furnished to the SEC on Form 8-K in connection with the quarterly reporting of our results of operations and financial condition.
2024 LTI Awards for 2023 Performance
On January 25, 2024, the Committee approved LTI equity awards to NEOs for 2023 performance using the same mix of time-based, full-value equity awards and performance-based MYLTIP awards as in prior years. The 2024 MYLTIP awards were denominated in a fixed number of LTIP units.
Based on the NEOs’ performance in 2023, the Committee awarded the dollar values set forth below for performance-based and time-based equity awards granted to the NEOs on February 6, 2024 and February 2, 2024, respectively, for performance in 2023. These total LTI equity award amounts reflect 100% of each NEO’s target LTI award value for 2023. Under his employment agreement, Mr. Ritchey was not eligible to receive an LTI equity award for 2023 performance.

The aggregate target number of 2024 MYLTIP units for NEOs is approximately 160,005 LTIP units, and an aggregate payout opportunity ranging from zero to a maximum of 320,011 LTIP units. The baseline share price for 2024 MYLTIP awards was $64.288 (the average closing price per share of our common stock on the NYSE for the five trading days prior to and including February 6, 2024). The fair value of the 2024 MYLTIP awards is generally amortized into earnings over the three-year plan period under the graded vesting method (unless accelerated in certain circumstances such as a “Qualified Retirement” as defined under “—Potential Payments Upon Termination or Change in Control—Retirement Eligibility Provisions for LTI Equity Awards”). The awards are divided into three components with differing weightings: rTSR component (40%), aTSR component (40%) and Leverage Component (20%). In general, the Company will not make any expense adjustments over the three-year plan period for the rTSR and aTSR components. However, with respect to the Leverage Component, each quarter the Company will assess the number of LTIP units that it estimates will be earned and will account for any increase or decrease in the number of LTIP units as a cumulative adjustment to expense in that period. Under ASC Topic 718, the aggregate grant-date fair value of 2024 MYLTIP awards to NEOs was approximately $10.7 million.
92 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
Realized Pay vs. Reported Pay for MYLTIP Awards
The total compensation of our NEOs, as reported in the 2023 Summary Compensation Table, is calculated under SEC rules, which require us to show the grant date fair value of equity and equity-based awards. The Committee believes realized pay better measures compensation for an annual period than reported pay because a significant portion of our NEOs’ compensation consists of long-term, performance- and equity-based MYLTIPs, and the ability of our executive officers to realize value from MYLTIP awards is contingent on the Company's outperformance over a multi-year performance period. In contrast to realized pay, reported pay is the accounting value of MYLTIP awards granted in the given period, which may or may not be realized in the future.
As illustrated in the following chart and table, our CEO realized approximately 53% of the reported pay for all MYLTIP awards granted since 2018 for which the measurement periods have ended. Furthermore, because Mr. Thomas has never sold or redeemed any LTIP units, as of December 31, 2023, the aggregate value of the LTIP units Mr. Thomas earned under the 2018 – 2020 MYLTIP programs had decreased by an additional 26.5% (or approximately $1.5 million) from their value as of the dates earned. Similarly, the value of the time-based LTI equity awards Mr. Thomas received in calendar years 2018-2023 declined by approximately $8.6 million as of December 31, 2023. These outcomes underscore the difference in reported pay versus realized pay and substantiate the continuous alignment of our investors' experiences with those of our executives.

Determining Executive Compensation
Process for Determining Executive Compensation
Consistent with the prior year’s process, in January 2023, our Committee established target TDC opportunities for each of our NEOs consisting of base salary, target annual cash incentive, and target long-term incentive grant value. When establishing target TDC levels, the Committee considered a variety of factors, including:
industry and market conditions;
the Company’s financial and strategic performance, on both an absolute basis and versus competitors;
market compensation data among comparable companies;
individual executive past performance, future potential, roles and responsibilities, experience, retention risk, and succession planning;
total NEO compensation over time, both on an awarded basis and on a realized basis after forfeitures; and
current and evolving practices and trends among our peers, the market generally, and other input from FW Cook.
The Committee evaluated the pre-established performance goals under the 2023 AIP to determine earned annual incentives for 2023 (refer to page 88). The Committee determined 2024 LTI equity grant values (earned for 2023) by reference to the targets established at the beginning of the year (refer to page 92). The ultimate earned value of these LTI equity awards depends on our stock’s performance on both a relative and an absolute basis and our executives' leverage management.
Compensation Advisor's Role & Benchmarking Peer Group
Compensation Advisor’s Role
In 2023, the Committee again retained FW Cook as its independent, third-party compensation consultant. FW Cook advises the Committee on the reasonableness of executive compensation levels compared to those of other similarly situated companies, consults on the structure of our executive compensation program to optimally support our business objectives and advises the Committee on executive compensation trends among REITs and the broader market. FW Cook reports directly to the Committee and only provides services to management under the Committee’s purview. A representative of FW Cook attends meetings of the Committee, as requested, and communicates with the Committee Chair and management between meetings. Consistent with its charter and as required by SEC rules and NYSE listing standards, the Committee considered all factors relevant to FW Cook’s independence from management before retaining FW Cook as its consultant.
Benchmarking Peer Group
The Committee monitors the effectiveness of our executive compensation program on an ongoing basis. For it to be effective, compensation must be competitive with other large public real estate companies with which we compete for executive talent. The Committee uses industry peer group data to assess and determine pay for our executive officers. However, other REITs in the office sector and other sectors are not always comparable to us because of differences in underlying business fundamentals. Peer group data is intended to provide the Committee with insight across the peer group into market pay levels for each element of compensation and target TDC of executive officers having similar titles and responsibilities to our NEOs, market trends, “best” governance practices, and overall industry performance. The median (50th percentile) serves as a reference point and indicator of competitive market trends and the Committee uses it as the starting point when setting our executive compensation. However, market data is one of many factors the Committee considers when setting target pay opportunities.
FW Cook advised the Committee that size, as measured by total capitalization, best depicts the scale, complexity and breadth of the Company’s operations and the amount of capital and assets managed, and therefore is the most appropriate scope measure for peer company selection. Following a review of the peer group for 2022, FW Cook recommended, and the Committee agreed, to maintain the same peer group for 2023. Notably, thirteen out of the sixteen members of this Benchmarking Peer Group also listed BXP as a peer company in their 2023 proxy statements.

Role of Management in Compensation Decisions
Our CEO and President make recommendations to the Committee on the compensation of the other executive officers, and our CEO makes recommendations to the Committee on the compensation of our President, in each case, based on their assessment of performance versus corporate and individual goals and a variety of other factors (e.g., compensation history, tenure, responsibilities, market data for competitive positions and retention concerns). The Committee makes all executive compensation decisions.

Other Compensation Policies
Double-Trigger Acceleration of Vesting of Equity Awards Upon a Change of Control
All time-based equity awards made after 2014 include “double-trigger” vesting, meaning that if there is a “change of control” and the awards are not otherwise canceled in connection with the change of control transaction, then they only become fully vested if, within 24 months after the change of control, the executive’s employment is terminated by the Company or its successor without “cause” or the executive resigns for “good reason.” This policy regarding acceleration of vesting upon a change of control aligns with current best practices while also continuing to remove potential disincentives for executives to pursue a change of control transaction that would benefit stockholders. Although certain senior officers, including our CEO, were entitled to single-trigger vesting under their employment agreements, the Committee requested, and those executives voluntarily agreed to, the change. The Committee believes that this demonstrates its and management’s responsiveness to stockholders and that the policy addresses two key objectives:
Aligning executives’ interests with stockholders’ interests: When a change of control may be imminent, it is important to ensure that executives’ interests are aligned with stockholders to maximize stockholder value.
Minimizing conflicts of interest: Double-trigger vesting in the context of a potential change of control (1) reduces distraction and the risk that executives leave the Company before a transaction is completed and (2) prevents executives from receiving a windfall because executives’ time-based equity vests only if their employment is terminated.
Clawback Policy
In October 2023, our Board adopted a new Compensation Recovery Policy, or “clawback” policy, to comply with the requirements of Section 954 of the Dodd-Frank Act and the related rules and regulations promulgated by the SEC and NYSE ("New Clawback Policy"). The New Clawback Policy requires us to recover from covered executive officers any erroneously awarded incentive-based compensation that is earned, granted or vested based on the achievement of a financial reporting measure during the three fiscal years preceding the date on which the Company determines it is required to prepare a material financial restatement. The New Clawback Policy applies to all incentive-based compensation received by covered executive officers on or after October 2, 2023, that is in excess of the amount that would have been received had it been calculated based on the restated financial statements. However, compensation received prior to October 2, 2023 remains subject to the terms of our prior clawback policy ("Prior Clawback Policy"). Our Prior Clawback Policy allows us to recoup "excess compensation" from certain executive officers in the event of an accounting restatement due to material non-compliance with any financial reporting requirement. “Excess compensation” includes annual cash bonus and long-term incentive compensation in any form (including stock options, restricted stock and LTIP units, whether time-based or performance-based) received by them during the three years preceding the publication of the restated financial statements, that the Committee determines was in excess of the amount that they would have received had such compensation been determined based on the financial results reported in the restated financial statements. The New Clawback Policy has been filed as an exhibit to our Annual Report on Form 10-K.
Gross-Up for Excess Parachute Payments
In January 2014, we adopted a formal “no tax gross-up” policy with respect to our senior executives. Under this policy, we will not make or promise to make any tax gross-up payment to any senior executive in the future other than payments in accordance with obligations existing at the time of the policy’s adoption or under arrangements applicable to our management employees generally, such as a relocation policy. The employment agreements we have entered into with senior executives since 2013, including our current and past employment agreements with our CEO, Mr. Thomas, do not provide for tax gross-up payments. In addition, the Second Amended and Restated Employment Agreement with Mr. Ritchey provides that he will no longer be eligible to receive a tax gross-up payment under any plan or agreement. (See “Compensation of Executive Officers—Employment Agreements—Summary of Mr. Ritchey’s Employment Agreement.") Accordingly, this policy formalized the Committee’s then-existing practice with respect to tax gross-ups. In addition, our Senior Executive Severance Plan and Executive Severance Plan provide that executives who become eligible to participate in these plans after 2013 will not be entitled to any tax gross-up payments under the plans.

Compensation Discussion and Analysis/
Policy Concerning Hedging and Pledging Transactions
Transactions such as purchases and sales of publicly traded put and call options, short sales, hedging transactions such as prepaid variable forwards, equity swaps and collars create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an employee or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Therefore, we prohibit all employees, including our executive officers, and directors from engaging in short sales and derivative transactions, purchasing our securities on margin and pledging our securities as collateral for a loan.
Mandatory Minimum Equity Ownership Policy for Senior Executives
To align senior management with our stockholders and demonstrate to the investment community that our senior management is personally committed to our continued financial success, we have a policy that requires the following officer positions to maintain equity ownership equal to a multiple of their base salaries as follows:
TitleMultiple of Base Salary
Chief Executive Officer6.0x
President5.0x
Senior Executive Vice President5.0x
Executive Vice President, Chief Financial Officer3.0x
Executive Vice President, Regional Manager2.0x
Senior Vice President1.5x
à
CEO Mandatory MinimumCEO Actual Stock Ownership
6xbase salary
43x
base salary
Mr. Thomas' actual stock ownership represents approximately 43 times his base salary (based on the last reported sale price of a share of BXP common stock on the NYSE on February 12, 2024), substantially greater than the mandatory minimum equity requirement. In fact, Mr. Thomas acquired approximately $1.0 million in BXP's common stock prior to joining BXP in 2013. Including those shares, since 2013, Mr. Thomas has never sold any shares of BXP common stock or redeemed any units in BPLP.
If an executive’s ownership falls below the applicable guideline due solely to a decline in the value of our common stock, the executive will not be required to acquire additional shares to meet the guideline, but he or she will be required to retain all shares then held (except for shares withheld to pay withholding taxes or the exercise price of options) until the executive again attains the target multiple.
Employees hired or promoted to senior management positions will have five years beginning on January 1 of the year following their appointment to achieve this ownership requirement. Exceptions may be made for significant extenuating personal circumstances. The types of securities that are counted toward the equity ownership requirement include shares of our common stock, common units and LTIP units (excluding performance-based LTIP units until and unless they have been earned), in each case both vested and unvested, as well as shares acquired and held through our stock purchase and dividend reinvestment plans. Stock options are not counted.
BXP / 2024 Proxy Statement 97

/Compensation Discussion and Analysis
LTIP Units
Since 2003, we have used a class of partnership interests in our Operating Partnership, called long-term incentive units, or LTIP units, as a form of equity-based award for annual long-term incentive equity compensation. LTIP units are designed to qualify as “profits interests” in the Operating Partnership for federal income tax purposes, meaning that initially, they are not economically equivalent in value to a share of our common stock, but over time can increase in value to one-for-one parity with common stock by operation of special tax rules applicable to profits interests. LTIP units offer executives a long-term incentive comparable to restricted stock while allowing them to enjoy a more favorable income tax treatment. Each LTIP unit awarded is deemed equivalent to an award of one share of common stock reserved under our incentive equity plan. The key difference between LTIP units and restricted stock is that at the time of award, LTIP units do not have full economic parity with common units but can achieve such parity over time upon the occurrence of specified events in accordance with partnership tax rules. Until and unless such parity is reached, the value that an executive will realize for a given number of vested LTIP units is less than the value of an equal number of shares of our common stock.
Under the MYLTIP awards, during the performance period, holders of LTIP units will receive distributions equal to one-tenth (1/10th) of the amount of regular quarterly distributions paid on a common unit, but will not receive any special distributions. After the end of the performance period, holders of earned LTIP units, both vested and unvested, will be entitled to receive distributions in an amount per LTIP unit equal to the distributions, both regular and special, payable on a common unit (which equal per share dividends (both regular and special) on our common stock). For the 2021 MYLTIP – 2024 MYLTIP awards, following the completion of their respective three-year performance periods, BXP will also make a “catch-up” cash payment on the LTIP units that are ultimately earned in an amount equal to the regular and special dividends, if any, declared during the performance period on BXP common stock, less the distributions paid to holders of the applicable MYLTIP awards, during the applicable performance period on all of the corresponding LTIP units. LTIP units awarded with time-based vesting conditions only, both vested and unvested, are entitled to receive distributions per LTIP unit equal to the regular and special distributions payable on a common unit.
Employment Agreements
During 2023, we had employment agreements with each of our NEOs. (See “Compensation of Executive Officers—Employment Agreements” beginning on page 111.) For NEOs other than Mr. Thomas, these agreements provide for a certain level of severance, generally the sum of base salary plus the prior year’s cash bonus, 12 additional months of vesting in equity-based awards and participation in our health plan for up to 12 months, in the event of a termination of employment by us without cause or by the executives for good reason. The employment agreement with Mr. Thomas provides for stipulated severance benefits in lieu of participation in severance plans for which the other NEOs are eligible. In return, each NEO agrees, during the term of employment and for one year thereafter, not to compete with us, solicit our clients or employees or interfere with our relationship with our clients, suppliers, contractors, lenders, employees or with any governmental agency. We believe these agreements are fair to the NEOs and our stockholders and, because the severance benefits are negotiated at the time of the agreement, avoid the need for protracted negotiations in the event of termination.
Change in Control Arrangements
We have an employment agreement with Mr. Thomas that provides him with cash severance and certain benefits in the event of his termination under certain circumstances within 24 months following a change in control. Although Mr. Thomas was entitled to “single-trigger” vesting upon a change in control under his original employment agreement, he has agreed to be subject to the “double-trigger” vesting policy adopted for all time-based LTI equity awards made after 2014. We also have two change in control severance plans, one for our President and Executive Vice Presidents, and the other for our Senior Vice Presidents and those Vice Presidents with ten (10) or more years of tenure with us. These plans also provide cash severance and certain benefits in the event of termination of employment under certain circumstances within 24 months following a change in control. The two change in control severance plans are “double trigger” arrangements, providing severance benefits only upon an involuntary or constructive termination of the executive officer following a change in control. (See “Compensation of Executive Officers—Potential Payments Upon Termination or Change in Control” beginning on page 115.) Officers who became eligible under the two severance plans described above prior to their amendment in January 2014 upon adoption by the Committee of a formal “no tax gross-up” policy are entitled to a gross-up payment in the event they become subject to the 20% golden parachute excise tax. This was the market practice when these plans were adopted in 1998. Messrs. Thomas and Ritchey are not entitled to a tax gross-up payments under their employment agreements.
98 BXP / 2024 Proxy Statement

Compensation Discussion and Analysis/
In our experience, change in control cash severance protection for executive officers is common in the REIT industry. Our Committee believes it is fair to provide severance protection in the event of an involuntary termination or constructive termination of employment following a change in control because senior manager positions are often eliminated following a change in control. The Committee believes that agreeing in advance to provide severance benefits in the event of an involuntary termination or constructive termination of employment following a change in control helps reinforce and encourage the continued attention and dedication of senior management to their assigned duties without distraction in the face of an actual or threatened change in control and helps ensure that management is motivated to negotiate the best consideration for our stockholders. For treatment of equity awards in the event of a change in control, please see “—Double-Trigger Acceleration of Vesting of Equity Awards upon a Change of Control” above.
Perquisites
Mr. Thomas’ employment agreement provides that he is entitled to the use of a Company-owned or leased vehicle, but Mr. Thomas has declined this benefit since 2013. We provide Messrs. Linde, Ritchey and Koop a monthly car allowance of $750 and all of our executive officers a designated parking space. Apart from these arrangements, we do not provide any other perquisites to our executive officers.
Deferred Compensation Plan
We offer a deferred compensation plan that permits our executives to defer up to 20% of their base salaries and bonuses. The amounts deferred are not included in the executive’s current taxable income and, therefore, are not currently deductible by us. The executives select from a limited number of mutual funds, which serve as measurement funds. The deferred amounts are increased or decreased to correspond to the market value of the mutual fund investments. Because the measurement funds are publicly traded securities, we do not consider any of the earnings credited under the deferred compensation plan to be “above market.” We do not provide any matching contribution to any executive officer who participates in this plan, other than a limited amount to compensate for any loss of matching contributions under our Section 401(k) plan. We have made this plan available to our executives to ensure our benefits are competitive. See “Compensation of Executive Officers—Nonqualified Deferred Compensation in 2023” beginning on page 109.
Retirement and Health and Welfare Benefits
We have never had a traditional or defined benefit pension plan. Our executives participate in Company-sponsored benefit programs available broadly to generally all of our salaried employees, including our employee stock purchase plan and our Section 401(k) plan. We maintain a Section 401(k) retirement plan in which all salaried employees can participate, which provides a Company matching contribution of 200% of the first 3% of compensation contributed to the plan (utilizing earnings not in excess of an amount established by the Internal Revenue Service ($330,000 in 2023)). Other benefits, such as health and dental plans, group term life insurance, short- and long-term disability insurance and travel accident insurance, are also generally available to our salaried employees.
Deductibility of Executive Compensation
The Committee’s policy is to consider the tax treatment of compensation paid to our executive officers while simultaneously seeking to provide our executives with appropriate rewards for their performance. Under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), a publicly held corporation may not deduct compensation of more than $1 million paid to any “covered employee.” To the extent that compensation paid to our executive officers is subject to and does not qualify for deduction under Section 162(m), our Committee is prepared to exceed the limit on deductibility under Section 162(m) to the extent necessary to establish compensation programs that we believe provide appropriate incentives and reward our executives relative to their performance. Because we qualify as a REIT under the Code, we generally distribute at least 100% of our net taxable income each year and therefore do not pay federal income tax. As a result, the possible loss of a federal tax deduction would not have a material impact on us.
Accounting for Stock-Based Compensation
We account for stock-based awards under the requirements of ASC Topic 718.
BXP / 2024 Proxy Statement 99

/Compensation Discussion and Analysis
Assessment of Compensation-Related Risks
The Committee is responsible for overseeing the risks relating to compensation policies and practices affecting senior management on an ongoing basis. The Committee believes that, because of the following factors, there is a low likelihood that our compensation policies and practices would encourage excessive risk-taking:
Risk Mitigation Factors
our policies and programs are generally intended to encourage executives to focus on long-term objectives;
overall compensation is maintained at levels that are competitive with the market;
the mix of compensation balances cash and equity compensation, incentives for short-term and long-term performance, and financial, strategic and market-based measures;
annual cash bonuses for executives are linked to performance against goals in three categories with specific weightings and each executive has target and maximum bonus opportunities;
long-term equity incentives align management’s interests with those of stockholders with the performance-based components rewarding company and executive outperformance and being capped at 200% of target shares;
except for those employees who satisfy the conditions for Qualified Retirement, all equity awards are subject to multi-year vesting (see “—Potential Payments Upon Termination or Change in Control—Retirement Eligibility Provisions for LTI Equity Awards” on page 118);
executive officers are subject to minimum stock ownership guidelines and limitations on trading in our securities, including prohibitions on hedging and pledging; and
a clawback policy permits the Company to recoup compensation paid on the basis of financial results that are subsequently restated.
Equity Award Grant Policy
We have a policy that annual grants to employees are approved by the Committee in late January or early February of each year, with an effective grant date immediately following the closing of the NYSE on the second trading day after we publicly release financial results for the prior year. This policy provides the necessary certainty and transparency for employees and stockholders while allowing the Committee desired flexibility.
Our Committee approves equity awards in dollar values. To the extent these awards are paid in the form of full-value awards (either shares of restricted stock and/or LTIP units), the number of shares/units granted is calculated by dividing the dollar value of the approved awards by the closing market price on the NYSE of a share of our common stock on the effective date of grant. To the extent these awards are made in stock options, the number of shares underlying option grants is determined by dividing the dollar value of the approved awards by the grant-date fair value of the option, as calculated by an independent valuation expert in accordance with ASC Topic 718. The Equity Award Grant Policy does not apply to performance-based equity awards such as the MYLTIP because of the different considerations that apply to granting such awards. For example, consistent with our past practice when granting multi-year, performance-based equity awards, the Committee determined that the baseline share price from which TSR performance is measured for the two TSR-linked components of the 2024 MYLTIP should be based on the average closing stock price for the five trading days prior to and including the effective date of grant.

1.For a discussion of the Company’s policy with respect to the effective grant dates for equity-based awards, see “Compensation Discussion and Analysis—Other Compensation Policies—Equity Award Grant Policy” on page 100.
2.Except in the case of Mr. Ritchey, represents the potential payouts at the threshold, target and maximum performance levels under the 2023 Annual Incentive Plan, as described under “Compensation Discussion and Analysis—2023 Executive Compensation—Cash Compensation—2023 Annual Incentive Plan" beginning on page 76. The amount shown for Mr. Ritchey represents the potential payout at target performance level in accordance with his employment agreement. The actual bonuses paid to Mr. Ritchey pursuant to his employment agreement and to each other NEO under the 2023 Annual Incentive Plan are reported in the Summary Compensation Table on page 102 in the column “Non-Equity Incentive Plan Compensation" for 2023.
3.Represents 2023 MYLTIP awards for each NEO. Performance-based vesting of 2023 MYLTIP awards will be measured on the basis of BXP’s relative and absolute TSR performance over a three-year performance period ending February 6, 2026. The 2023 MYLTIP awards consist of two, equally weighted components (50% - 50%). The number of LTIP units that can be earned under the first component ranges from zero to 200% of the target number of LTIP units, based on BXP’s annualized TSR performance relative to the Custom Index. The number of LTIP units that can be earned under the second component ranges from zero to 200% of the target number of LTIP units, based on BXP’s cumulative absolute TSR during the performance period. See “Compensation Discussion and Analysis—2023 Executive Compensation—LTI Equity Compensation—Allocation of LTI Equity Awards—2023 MYLTIP Structure & Design” beginning on page 90. During the three-year performance period, holders of 2023 MYLTIP awards are entitled to receive only a partial distribution on each unit equal to 10% of the regular dividend payable on a share of BXP common stock. Following the completion of the three-year performance period, BXP will make a “catch-up” cash payment on the 2023 MYLTIP awards that are ultimately earned, if any, in an amount equal to the regular and special distributions, if any, declared during the performance period on an equal number of shares of BXP common stock, less the distributions actually paid to holders of 2023 MYLTIP awards during the performance period on all of the awarded 2023 MYLTIP awards.

Compensation of Executive Officers/
4.Stock awards were made in the form of shares of restricted common stock and/or LTIP units at the election of each NEO. Each NEO other than Mr. LaBelle, elected to receive all LTIP units. Mr. LaBelle elected to receive 75% of his award as LTIP units and 25% of his award as shares of restricted common stock. Dividends are payable on restricted common stock and distributions are payable on the LTIP units to the same extent and on the same date that dividends and distributions are paid on BXP common stock and common units of our Operating Partnership, respectively. Grantees of restricted common stock pay $0.01 per share and grantees of LTIP units pay $0.25 per unit. The awards are scheduled to vest over a four-year period with 25% vesting on January 15 of each year beginning January 15, 2024, based on continued employment through such date, subject to acceleration under certain circumstances. An employee who had attained age 65 or attained age 62 with 20 years of service with us prior to February 1, 2019 became fully vested in all time-based LTI equity awards granted on February 3, 2023. Mr. Ritchey satisfied this policy and is fully vested in his time-based LTI equity award granted on February 3, 2023. Pursuant to his employment agreement, on July 1, 2023, when Mr. Thomas attained age 62 and completed ten (10) years of service with us, he became fully vested in all time-based equity awards. All other employees will become fully vested when the employee retires after the date on which the sum of the employee’s years of service plus age (which must be at least 58) equals or exceeds 70 (the so-called “Rule of 70”) and satisfies the other conditions of a “Qualified Retirement” as described under “—Potential Payments Upon Termination or Change in Control—Retirement Eligibility Provisions for LTI Equity Awards” beginning on page 118. Each of Messrs. Linde, LaBelle and Koop satisfied the Rule of 70 and is eligible for a Qualified Retirement with respect to his time-based LTI equity award granted on February 3, 2023.
5.The amounts included in this column represent the grant date fair values of the restricted common stock awards, LTIP unit awards and 2023 MYLTIP awards determined in accordance with ASC Topic 718, disregarding for this purpose the estimate of forfeitures related to service-based vesting conditions. A discussion of the assumptions used in calculating these values can be found in Note 15 to our 2023 audited financial statements beginning on page 186 of our Annual Report on Form 10-K for the year ended December 31, 2023 included in the annual report that accompanied this proxy statement.

a.The vesting of time-based LTI equity awards and performance-based LTI equity awards is subject to acceleration under certain circumstances and other exceptions discussed below under "—Potential Payments Upon Termination or Change in Control” beginning on page 115.
b.Time-based LTI equity awards generally are scheduled to vest ratably over four years, with 25% of the total award vesting on January 15 of each year beginning January 15 in the year following the grant, based on continued employment through such date, subject to acceleration under certain circumstances.
c.On February 3, 2023, the measurement period for the 2020 MYLTIP awards ended and the plan participants earned and therefore became eligible to vest in a portion of the 2020 MYLTIP awards. Fifty percent (50%) of these earned 2020 MYLTIP awards vested on February 3, 2023 and 50% vested on February 3, 2024.
d.As of December 31, 2023, all of Mr. Thomas' time-based equity awards and earned performance-based equity awards were vested and all of Mr. Ritchey’s time-based LTI equity awards were vested because they each satisfied the conditions for retirement eligibility for these awards. These policies are described below under “—Potential Payments Upon Termination or Change in Control—Retirement Eligibility Provisions for LTI Equity Awards” beginning on page 118.
3.The market value of these holdings is based on the closing price of BXP common stock as reported on the NYSE on December 29, 2023 of $70.17 per share.

a.The vesting of performance-based LTI equity awards is subject to acceleration under certain circumstances discussed below under "—Potential Payments Upon Termination or Change in Control.”
b.On February 2, 2021, the NEOs received 2021 MYLTIP awards. In accordance with SEC rules, the number of 2021 MYLTIP awards reported in this table represents the sum of the LTIP units that would be earned based on achieving (i) "target” performance with respect to the portion of the LTIP units eligible to be earned based on absolute TSR and (ii) “maximum” performance with respect to the portion of the LTIP units eligible to be earned based on relative TSR. If our absolute and relative TSR performance during the entire performance period are the same as our performance from the beginning of the performance period through December 31, 2023, our NEOs would earn (i) a number of LTIP units that is between threshold and target based on absolute TSR and (ii) a number of LTIP units that is between target and maximum based on TSR relative to a custom peer group index. The performance period for assessing performance ended on February 1, 2024. For the performance period, (i) BXP's absolute TSR was -11.54% and (ii) the annualized TSR for a custom peer group index was -10.30% and for BXP was -4.01%, resulting in BXP performance of 629 basis points. As a result, the final valuation for the awards was determined to be 57% of target for the absolute component and 163% of target for the relative component, or an aggregate of approximately $9.95 million for the NEOs as a group. Subject to the provisions on “Qualified Retirement” and the other terms of the award agreement, all earned awards are deemed “vested,“ but may not be converted, redeemed, sold or otherwise transferred for one additional year after the end of the performance measurement period. Therefore, 100% of the earned awards vested on February 1, 2024, but may not be monetized until February 1, 2025.
c.On February 1, 2022, the NEOs received 2022 MYLTIP awards. The measurement period for assessing performance ends on January 31, 2025. In accordance with SEC rules, the number of 2022 MYLTIP awards reported in this table represents the sum of the LTIP units that would be earned based on achieving (i) “target” performance with respect to the portion of the LTIP units eligible to be earned based on absolute TSR and (ii) “target” performance with respect to the portion of the LTIP units eligible to be earned based on relative TSR. If our absolute and relative TSR performance during the entire performance period are the same as our performance from the beginning of the performance period through December 31, 2023, our NEOs would earn (i) a number of LTIP units that is between threshold and target based on absolute TSR and (ii) a number of LTIP units that is between threshold and target based on TSR relative to a custom peer group index. Subject to the provisions of a “Qualified Retirement” and the other terms of the award agreement, after the completion of the three-year performance period all earned awards shall be deemed “vested,“ but may not be converted, redeemed, sold or otherwise transferred for one additional year after the end of the performance measurement period. Therefore, 100% of earned awards, if any, shall vest as of January 31, 2025, based on continued employment through such date, but may not be monetized until January 31, 2026.
d.On February 7, 2023 the NEOs received 2023 MYLTIP awards. The measurement period for assessing performance ends on February 6, 2026. In accordance with SEC rules, the number of 2023 MYLTIP awards reported in this table represents the sum of the LTIP units that would be earned based on achieving (i) “target” performance with respect to the portion of the LTIP units eligible to be earned based on absolute TSR and (ii) “target” performance with respect to the portion of the LTIP units eligible to be earned based on relative TSR. If our absolute and relative TSR performance during the entire performance period are the same as our performance from the beginning of the performance period through December 31, 2023, our NEOs would earn (i) a number of LTIP units that is between threshold and target based on absolute TSR and (ii) a number of LTIP units that is between threshold and target based on TSR relative to the Custom Index. See "Compensation Discussion and Analysis—2023 Executive Compensation—LTI Equity Compensation—Allocation of LTI Equity Awards—2023 MYLTIP Structure & Design" beginning on page 90. Subject to the provisions of a “Qualified Retirement” and the other terms of the award agreement, after the completion of the three-year performance period all earned awards shall be deemed “vested,“ but may not be converted, redeemed, sold or otherwise transferred for one additional year after the end of the performance measurement period. Therefore, 100% of earned awards, if any, shall vest as of February 6, 2026, based on continued employment through such date, but may not be monetized until February 6, 2027.

Under the deferred compensation plan, account balances are generally paid (1) in a lump sum upon the executive’s termination of employment prior to attainment of retirement age (as defined in the plan to be age 55 with five years of service) or the executive’s death, or (2) in a lump sum upon the executive's actual retirement or annual installments for a period of up to 15 years following such retirement (as previously selected by the executive at the time of deferral). Payments will generally start or be made by the later of (x) January 15 following the year of termination or retirement, or (y) six months after the executive’s termination or retirement. At the time of deferral, executives may also elect a fixed distribution date, which must be at least five years after the end of the calendar year in which amounts are deferred. The deferred compensation plan also permits an in-service withdrawal of the executive’s account balance attributable to pre-2005 deferrals, subject to a withdrawal penalty equal to 10% of the amount withdrawn.

Employment Agreements
We have employment agreements with each of our NEOs, other than Mr. Ritchey. Mr. Ritchey's employment agreement expired on December 31, 2023, and we have not entered into a new employment agreement with him. The material terms of these agreements and Mr. Ritchey's expired agreement are summarized below.
Summary of Owen D. Thomas’ Employment Agreement
We originally hired Mr. Thomas to be our CEO effective April 2, 2013. The initial term of Mr. Thomas’ employment agreement was three years, with automatic one-year renewals commencing on the third and fourth anniversaries of the effective date unless prior written notice of termination was given. The term of Mr. Thomas’ original employment agreement expired on April 2, 2018 on which date we entered into a new employment agreement with him (the "Thomas 2018 Agreement"). The Thomas 2018 Agreement expired on June 30, 2023 and we entered into a new employment agreement with him effective July 1, 2023. The following is a summary of Mr. Thomas’ current employment agreement:
Term and Duties
July 1, 2023 through December 31, 2026. There is no automatic renewal provision.
As CEO, Mr. Thomas reports directly to the Board of Directors, and he must devote substantially all of his working time and efforts to the performance of his duties.
Our Board agreed to nominate Mr. Thomas for re-election to the Board of Directors for so long as he remains CEO, and Mr. Thomas has agreed to resign from the Board upon termination of employment at the request of the Board.
Mr. Thomas may not serve on other boards of directors of for-profit companies without the consent of the Company's Board. Mr. Thomas may continue serving on the Board of Lehman Brothers Holdings Inc. and may engage in religious, charitable or other community activities, provided that they do not materially interfere with the performance of his duties to us as CEO. In addition, he may engage in “Minority Interest Passive Investments,” which are defined as acquiring, holding and exercising the voting rights associated with an investment made through (1) a non-controlling, minority interest in an entity or (2) the lending of money, in either case with the purpose or intent of obtaining a return on such investment but without management of the property or business to which the investment directly or indirectly relates and without any business or strategic consultation by Mr. Thomas with such entity.
Compensation and Benefits
Annual base salary of $950,000, subject to annual review and may be increased but not decreased in the discretion of the Compensation Committee. Mr. Thomas' 2024 base salary for 2024 remains unchanged at $950,000 (see "Compensation Discussion and Analysis—2023 Executive Compensation—Cash Compensation—Base Salary" beginning on page 75).
For each calendar year during the term, Mr. Thomas shall have the opportunity to earn a bonus based on the achievement of Company and individual performance goals and other criteria, as determined by the Compensation Committee. Mr. Thomas’ target annual bonus shall be $2,350,000, and this target may be increased but not decreased. The actual earned bonus may range from 0 to 150% of the target based on the Compensation Committee’s evaluation of the achievement of Company and individual performance goals and other criteria. The earned bonus for any calendar year shall be paid in cash no later than March 15 of the following calendar year. For the avoidance of doubt, if the term of the agreement ends on December 31, 2026, Mr. Thomas shall be entitled to receive his bonus for 2026, without any pro ration, notwithstanding that Mr. Thomas may no longer be employed by the Company on the date on which such bonuses for 2026 are paid in 2027.
Mr. Thomas is eligible to receive LTI equity awards in amounts determined at the discretion of the Compensation Committee based on Company and individual performance and competitive peer group information. LTI equity awards may be provided in the form of stock options, restricted stock, restricted stock units and/or LTIP units and may be subject to time-based or performance-based vesting, or both, as determined in the discretion of the Compensation Committee.

The Company paid the reasonable advisor fees (legal and tax) that Mr. Thomas incurred in connection with his current employment agreement in the aggregate amount of $11,926, which amount was subject to a maximum of $25,000.
Severance Benefits and Retirement Eligibility
Mr. Thomas' employment with us is at-will, but his employment agreement provides for certain payments and benefits to him upon his separation from the Company in certain circumstances (see "—Potential Payments upon Termination or Change in Control” beginning on page 115).
Because Mr. Thomas is at least 62 years of age and has completed at least ten (10) years of employment with the Company, Mr. Thomas is deemed to have satisfied the requirements for retirement eligibility and, as a result, the Agreement provides that (1) his time-based equity awards, whether currently outstanding or granted in the future, shall be deemed to be fully vested and (2) performance-based equity awards that are earned will vest in full (without any proration of the award based on service time). In addition, upon a Qualified Retirement, Mr. Thomas shall be entitled to a prorated portion of his annual bonus for the year in which he retires (see “—Potential Payments upon Termination or Change in Control" beginning on page 115).
Mr. Thomas is not entitled to participate in any of the Company’s change in control severance plans or programs and he is not entitled to receive any tax gross-up payments. In the event that any payment or benefit to be paid or provided to Mr. Thomas would be subject to the golden parachute excise tax under Section 280G of the Internal Revenue Code, the payments and benefits will be reduced to the extent necessary to avoid the imposition of the excise tax if doing so would result in a greater after-tax benefit to Mr. Thomas.
The expiration of Mr. Thomas’ agreement on December 31, 2026 (1) will not constitute or result in a termination of employment by the Company without Cause or termination of employment by Mr. Thomas for Good Reason, and the severance provisions (other than retirement eligibility and related benefits) shall not apply, and (2) will constitute a Qualified Retirement. In addition, notwithstanding the expiration of the term on December 31, 2026 and consistent with the Company’s historical practice in respect of retiring executives, in 2027 Mr. Thomas shall receive an annual equity incentive award(s) in respect of services provided during calendar year 2026, and the terms and conditions of such awards, including the grant date target value and, generally, the type(s) of awards, shall be determined in the discretion of the Compensation Committee.
Restrictive Covenants
While he is an officer and until the later of (1) one year after the termination of his employment for any reason or (2) the latest date of full vesting of any performance-based LTI equity award, Mr. Thomas is prohibited from:
participating as a significant owner or performing services in a senior leadership position of any business that owns, develops and manages primarily commercial office space real estate property at the time of termination of his employment; and
intentionally interfering with the Company’s relationships with certain of its tenants or employees, either for himself or any other business, person or entity.
The non-competition covenant shall not apply if Mr. Thomas’ employment is terminated following a change in control (as defined in the Boston Properties, Inc. 2021 Stock Incentive Plan, as amended from time to time (the "2021 Plan")).
Mr. Thomas is also subject to confidentiality requirements and post-termination litigation and regulatory cooperation obligations.

We also have employment agreements with Messrs. Linde, LaBelle and Koop – under which each has agreed to devote substantially all of his business time to our business and affairs. The initial term of each of these employment agreements was two years beginning November 29, 2002 (January 24, 2008 in the case of Mr. LaBelle), with automatic one-year renewals commencing on the second anniversary of the start of the initial term and each anniversary date thereafter unless written notice of termination is given at least 90 days prior to such date by either party.

The geographic scope of the noncompetition provision in each employment agreement is limited to our markets at the time of termination of the NEO's employment. In consideration for the benefits and protections afforded by the employment agreements, each of these NEOs agreed to confidentiality, non-competition, non-interference and non-solicitation covenants and to provide post-termination litigation and regulatory cooperation. These NEOs' employment with us is at-will, but their employment agreements also provide for certain payments and benefits to them upon separation from the Company in certain circumstances as described below under “—Potential Payments upon Termination or Change in Control."

Severance Benefits and Retirement Eligibility
Mr. Ritchey agreed that he is no longer a "covered employee" under the Company’s Senior Executive Severance Plan and is not entitled to receive any benefits thereunder, including any tax gross-up payments. In the event that any payment or benefit to be paid or provided to Mr. Ritchey would be subject to the golden parachute excise tax under Section 280G of the Internal Revenue Code, the payments and benefits will be reduced to the extent necessary to avoid the imposition of the excise tax if doing so would result in a greater after-tax benefit to Mr. Ritchey.

salary continuation for the period from the date of termination through December 31, 2023,
payment of the 2023 target annual bonus amount, and
continued participation in the Company’s health insurance plan for 12 months.

pursue an actual or potential investment or business opportunity in which the Company could have an interest or expectancy that are within the Company’s geographic market areas and that involve property types that are within the scope of the Company’s business activities (a "Corporate Opportunity"), other than minority interest passive investments, unless he first presents the Corporate Opportunity to the Company in accordance with the procedures set forth in the Ritchey 2023 Agreement and the Company elects not to pursue such Corporate Opportunity;

Potential Payments Upon Termination or Change in Control
Each NEO has the right to receive severance and other benefits in the event of a termination of his employment under different circumstances pursuant to their employment agreements (discussed under “—Employment Agreements” beginning on page 111) and, except for Messrs. Thomas and Ritchey, the Company’s Senior Executive Severance Plan. In addition, our LTI equity award agreements (including performance-based MYLTIP awards) provide for the vesting and forfeiture of LTI equity awards under different termination scenarios. The availability, nature and amount of severance and other benefits differ depending on the type of triggering event, which include:
a termination by the Company without “cause” (as defined in the applicable agreement or plan) or by the NEO with “good reason” (as defined in the applicable agreement or plan) prior to a change in control,
a termination by the Company without “cause” or by the NEO for “good reason” within 24 months following a change in control,
a change in control without termination,
termination due to death or disability, or
a qualified retirement.
Upon a voluntary termination by the NEO (i.e., termination by the NEO), other than for “good reason” or a qualified retirement, or a termination by the Company with “cause,” the NEO is not entitled to any additional or special payments under any plan, agreement or arrangement, and any unvested LTI equity awards will be immediately forfeited.
Summary of Potential Payments and Benefits
The following chart summarizes payments and benefits that (1) Mr. Thomas is eligible to receive under his employment agreement, (2) Mr. Ritchey was eligible to receive as of December 31, 2023 under the Ritchey 2023 Agreement (which expired as of December 31, 2023), (3) Messrs. Linde, LaBelle and Koop are eligible to receive under their respective employment agreements and our Senior Executive Severance Plan and (4) each NEO is entitled to receive under his performance-based LTI equity award agreements. As of the effective date of the Ritchey 2023 Agreement, Mr. Ritchey is no longer entitled to participate in any of the Company’s change in control severance plans or programs and he is no longer entitled to receive any tax gross-up payments. Mr. Thomas has never been a covered employee under the Senior Executive Severance Plan and the severance and benefits to which he is entitled following a termination within twenty-four (24) months after a change in control are provided in his employment agreement.

Double-Trigger Acceleration of Vesting of Equity Awards Upon a Change of Control
Time-based LTI equity award agreements include "double-trigger” vesting provisions, meaning that, if there is a “change in control” (as defined in the 2021 Plan) and the awards are not otherwise cancelled in connection with the change in control transaction, then they only become fully vested if, within 24 months after the change in control, the NEO’s employment is terminated by the Company or its successor without “cause” or the NEO resigns for “good reason.”

Retirement Eligibility Provisions for LTI Equity Awards
Retirement Provisions
Mr. Thomas. Pursuant to Mr. Thomas’ employment agreement, all LTI equity award agreements after July 1, 2023 shall provide that because Mr. Thomas has attained age 62 and has completed at least ten (10) years of employment with us, then his time-based LTI equity awards will be fully vested upon grant and performance-based LTI equity awards that are earned will vest in full (without any proration of the award based on service time).
The full number of LTIP units Mr. Thomas earns (if any) under any performance-based LTI equity awards for which the performance period has not ended will be determined in the same manner and at the same time as otherwise would have been the case if he had remained employed through the full performance period for the applicable award, including, without limitation, with respect to performance hurdles and lapse of restrictions on transfer, without any proration of the award due to service time, and with all service-based vesting requirements deemed satisfied, so long as he agrees to be bound by the post-employment non-competition, non-interference and non-solicitation covenants (which are otherwise applicable until the later of (1) one (1) year following termination and (2) the latest date of full vesting of any performance-based LTI equity award).
NEOs other than Mr. Thomas. The agreements governing time-based LTI equity awards and performance-based LTI equity awards granted to NEOs other than Mr. Thomas provide that the time-based LTI equity awards and performance-based LTI equity awards that are earned will fully vest when the employee retires after the date on which the sum of the employee’s years of service plus age (which must be at least 58) equals or exceeds 70 (the so-called “Rule of 70”) (“Qualified Retirement”); provided that the NEO satisfies the other conditions of a “Qualified Retirement,” which require the employee to:
give prior written notice to the Company of his retirement (for NEOs, six (6) months’ notice is required),
enter into a separation agreement with the Company and
remain employed by the Company until the retirement date specified in such notice, unless employment is terminated by the Company without “cause” or by the employee for “good reason.”
If an NEO retires after satisfying the conditions for a Qualified Retirement, the number of LTIP units the NEO earns (if any) under performance-based LTI equity awards will be determined in the same manner and at the same time as otherwise would have been the case if he had remained employed through the entire performance period for the applicable award, including with respect to performance hurdles and lapse of restrictions on transfer, without any proration of the award due to service time. Any earned, unvested LTIP units will no longer be subject to forfeiture but the NEO will not be permitted to transfer the LTIP units until they otherwise would have the right to transfer the LTIP units under the terms of the awards.
Pre-2019 Policy
Time-based LTI equity awards granted prior to 2019 provide that when an employee attains age 65, or attains age 62 and completes 20 years of service with us, the employee becomes fully vested in all time-based LTI equity awards (the "Pre-2019 Policy"). In addition, time-based LTI awards made to employees who, on or prior to January 31, 2019, attained age 65 or attained age 62 with 20 years of service retain their status under the Pre-2019 Policy such that subsequent time-based LTI awards will continue to be fully vested on the date of grant.
NEOs Eligible for Qualified Retirement as of December 31, 2023
Based on their respective ages and tenure as of December 31, 2023:
Each of Messrs. Linde, LaBelle and Koop is eligible for a Qualified Retirement (i.e., he satisfied the Rule of 70) with respect to all time-based and performance based LTI equity awards granted in 2019 and thereafter.
Mr. Ritchey satisfied the Pre-2019 Policy and thus retains his status under such policy with respect to his time-based LTI equity awards. Therefore, all of Mr. Ritchey's time-based equity awards were fully vested as of December 31, 2023. Mr. Ritchey is also eligible for a Qualified Retirement with respect to all performance-based LTI equity awards granted in 2019 and thereafter.

The values set forth above relating to the LTIP units that would have been earned in the event of a Qualified Retirement, involuntary not for cause termination/good reason termination, death or disability assume our performance for the three-year performance period under the 2021 MYLTIP awards, 2022 MYLTIP awards and 2023 MYLTIP awards, respectively, was the same as our performance from the first day of the respective performance period through December 31, 2023 with proration, as applicable, but are not discounted to reflect the fact that such LTIP units would not be earned until a later date and would be subject to continuing transfer restrictions in the case of Qualified Retirement and involuntary termination prior to a change in control. The value for each of the 2021 MYLTIP awards, 2022 MYLTIP awards and 2023 MYLTIP awards also includes a “catch-up” cash payment on the number of LTIP units that are ultimately earned in an amount equal to the regular and special distributions declared from the first day of the applicable performance period through December 31, 2023 on an equal number of shares BXP common stock, less the distributions actually paid to holders of 2021 MYLTIP awards, 2022 MYLTIP awards and 2023 MYLTIP awards on all of the awarded 2021 MYLTIP awards, 2022 MYLTIP awards and 2023 MYLTIP awards.
4.Assumes termination occurs simultaneously with a change in control.
5.Includes outplacement services valued at 15% of the sum of current base salary plus bonus with respect to the immediately preceding year up to a maximum of $75,000 paid in a lump sum, and financial counseling and tax preparation services valued at $25,000 per year for 36 months.
6.Under their employment agreements, neither Mr, Thomas nor Mr. Ritchey is entitled to receive tax gross-up payments in the event he becomes subject to the golden parachute excise tax. Instead, if any payment or benefit to be paid or provided to Messrs. Thomas or Ritchey would be subject to the golden parachute excise tax, the payments and benefits will be reduced to the extent necessary to avoid the imposition of such tax if doing so would result in a greater after-tax benefit to him. The amounts set forth in the table above have not been adjusted to reflect any such reduction that might apply.
The above discussion and the amounts shown in the above tables do not include payments and benefits to the extent they have been earned prior to the termination of employment or are provided on a non-discriminatory basis to salaried employees upon termination of employment. These include:
accrued salary and vacation pay;
distribution of plan balances under our 401(k) plan and the non-qualified deferred compensation plan (see “—Nonqualified Deferred Compensation in 2023” for the plan balances of each NEO under the non-qualified deferred compensation plan); and
life insurance proceeds in the event of death.

Compensation of Executive Officers/
Pay Ratio Disclosure
As required by SEC regulations, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of Mr. Thomas, our CEO:
For 2023, our last completed fiscal year:
the median of the annual total compensation paid to all employees of the Company (other than our CEO) was $134,611; and
the annual total compensation of our CEO, as reported in the Summary Compensation Table on page 102, was $12,963,964.
Based on this information, for 2023, the ratio of the annual total compensation of Mr. Thomas to the median of the annual total compensation of all other employees was 96.3 to 1.
We identified the median employee by totaling (1) cash compensation (i.e., wages, overtime and bonus) as reflected on our payroll records for 2023 and (2) the value of LTI equity awards that were granted in 2023 and subject to time-based vesting, for all individuals, excluding our CEO, who we employed on December 31, 2023 (whether on a full-time, part-time, temporary or seasonal basis). In addition, we annualized the wages of full-time employees who were hired during 2023 but did not work for us the entire fiscal year. We did not make any other assumptions, adjustments, or estimates with respect to total cash compensation or LTI compensation.
We calculated annual total compensation for 2023 for the median employee using the same methodology we use for our NEOs as set forth in the Summary Compensation Table.
As of December 31, 2023, we employed 820 full-time and 16 part-time employees, all of whom are located in the United States. The average tenure of our employee population (excluding union employees and intern employees) was 9.2 years. The average tenure of our officers and non-officers was 18.5 years and 7.6 years, respectively. Our employees are organized into the following functions:
FunctionNumber of EmployeesFunctionNumber of Employees
Accounting 95Information Systems 44
Accounting Operations 18Internal Audit 3

SEC regulations permit registrants to use reasonable estimates and prescribed alternative methodologies. As a result, our calculation of the CEO pay ratio may differ from the calculations used by other companies and may not be comparable.

The dollar amounts do not reflect the actual amount of compensation earned by or paid to our CEO or Non-CEO NEOs during the applicable year. In accordance with Item 402(v) of Regulation S-K, CAP for our CEO and Average Cap for our Non-CEO NEOs was computed as follows:

Proposal 2 / Advisory Vote on Named Executive Officer Compensation
Proposal
Section 14A(a)(1) of the Exchange Act generally requires each public company to include in its proxy statement a separate resolution subject to a non-binding stockholder vote to approve the compensation of the Company’s NEOs, as disclosed in its proxy statement pursuant to Item 402 of Regulation S-K, not less frequently than once every three years. This is commonly known as a “Say-on-Pay” proposal or resolution.
At our 2023 annual meeting of stockholders, our stockholders voted on a proposal regarding the frequency of holding a non-binding, advisory vote on the compensation of our NEOs. More than 97% of the votes cast on the frequency proposal in 2023 were cast in favor of holding a non-binding, advisory vote on the compensation of the Company’s NEOs every year, which was consistent with the recommendation of our Board of Directors. Our Board of Directors considered the voting results with respect to the frequency proposal in 2023, as well as the voting results in 2011 and 2017, and other factors and caused the Company to hold a non-binding, advisory vote on the compensation of the Company’s NEOs every year since 2011. The next required advisory vote on the frequency of holding the non-binding, advisory vote on the compensation of our NEOs will occur at the 2029 annual meeting of stockholders.
Accordingly, we will ask our stockholders to vote “FOR” the following resolution at the 2024 annual meeting:
“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed in this proxy statement pursuant to the Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED.”
The vote is advisory and therefore not binding on BXP, our Board of Directors or the Compensation Committee. However, our Board of Directors and our Compensation Committee value the opinions of our stockholders and will consider the results of the vote when considering future compensation decisions for our NEOs.
Vote Required
The affirmative vote of a majority of shares of common stock present in person or represented by proxy at the meeting and entitled to vote on this proposal is required for the approval of this proposal. Abstentions shall be included in determining the number of shares present and entitled to vote on the proposal, thus having the effect of a vote against the proposal. Broker non-votes, if any, are not counted in determining the number of shares present and entitled to vote and will therefore have no effect on the outcome.

Recommendation of the Board
The Board of Directors unanimously recommends a vote "FOR" the approval of the compensation paid to the Company's NEOs as disclosed in this proxy statement. Properly authorized proxies solicited by the Board of Directors will be voted "FOR" this proposal unless instructions to the contrary are given.

Proposal 3 / Approval of the Fourth Amendment to the Boston Properties, Inc. 1999 Non-Qualified Employee Stock Purchase Plan
Proposal
We are asking our stockholders to approve the fourth amendment (the “Fourth Amendment”) to the Boston Properties, Inc. 1999 Non-Qualified Employee Stock Purchase Plan, as the same has been amended from time to time (the “ESPP”). A copy of the ESPP (with prior amendments reflected by underlines and strike-throughs) is attached to this proxy statement as Appendix B, together with a copy of the Fourth Amendment.
We originally reserved 250,000 shares of our common stock for issuance under the ESPP. As of March 27, 2024, 31,622.94 shares remained available for purchases under the ESPP. The sole purpose of the Fourth Amendment is to increase the number of shares of common stock authorized for issuance under the ESPP by 250,000 shares. Our Board of Directors approved the Fourth Amendment on January 25, 2024, subject to stockholder approval at the 2024 annual meeting. The ESPP is not intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”).
The purpose of the ESPP is to provide our employees the opportunity to purchase our common stock through accumulated payroll deductions or lump-sum cash contributions. The ESPP is an important component of the benefits package that we offer to our employees. We believe that it assists in retaining existing employees, recruiting and retaining new employees and aligning and increasing the interests of all employees in the success of BXP.
If our stockholders approve this proposal at the 2024 annual meeting, the Fourth Amendment authorizing the issuance of the additional 250,000 shares (which represents approximately 0.16% of the total 157,049,172 shares of our common stock that were issued and outstanding as of the record date of March 27, 2024) will become effective on May 22, 2024. All other existing provisions of the ESPP will remain in effect without change. If our stockholders do not approve the Fourth Amendment, then (1) the proposed 250,000 additional shares will not become available for issuance under the ESPP, and (2) after issuance of the remaining 31,622.94 shares authorized for issuance under the ESPP as of March 27, 2024, we will not have sufficient shares to continue to offer our employees this valuable benefit. We believe that the proposed increase in the number of shares authorized for issuance under the ESPP pursuant to the Fourth Amendment is reasonable, appropriate, and in the best interests of our stockholders.
Based solely on the closing price of our common stock reported on the NYSE on March 27, 2024, the maximum aggregate market value of the 31,622.94 shares of common stock that remain authorized for issuance under the ESPP is approximately $1,996,989.

Recommendation of the Board
The Board of Directors unanimously recommends a vote "FOR" the approval of the Fourth Amendment to the Boston Properties, Inc. 1999 Non-Qualified Employee Stock Purchase Plan. Properly authorized proxies solicited by the Board of Directors will be voted "FOR" this proposal unless instructions to the contrary are given.

Proposal 3/
Summary of the Material Provisions of the ESPP
The following is a summary of certain essential features of the ESPP. This summary is qualified in its entirety by the full text of the ESPP, which is attached hereto as Appendix B, together with a copy of the Fourth Amendment.
Shares Available for Issuance
The maximum number of shares of our common stock that will be available for issuance under the ESPP will be 500,000, which includes the 250,000 shares of common stock reserved for issuance under the ESPP as in effect on May 22, 2024. The shares available for issuance under the ESPP may be authorized but unissued shares or shares we acquire on the open market. If our capital structure changes because of a stock dividend, stock split or similar event, the number of shares we can issue under the ESPP will be appropriately adjusted.
Plan Administration
Except for the exercise of those powers expressly granted to our Compensation Committee, BXP is responsible for the administration of the ESPP and has the power to interpret the ESPP and to take such other actions in connection with the administration of the ESPP as BXP deems necessary or equitable under the circumstances.
Eligibility
Any officer or employee of any of BXP, the Operating Partnership, BP Management, L.P., or Boston Properties Management, Inc., and any other organization owned in whole or in part, directly or indirectly, by BXP that our Compensation Committee may designate (each, a “participating employer”), who is shown on the payroll records of a participating employer as an employee prior to the last day of an applicable election period is eligible to participate in the ESPP; provided, however, employees who are covered by a collective bargaining agreement are not eligible to participate in the ESPP unless participation is provided for in such collective bargaining agreement or previously approved pursuant to a plan amendment.
As of March 27, 2024, there were approximately 12 executive officers and 820 non-executive officer employees who would be eligible to participate in the ESPP. Non-employee directors are not eligible to participate in the ESPP.
Election Periods; Purchase Periods
Eligible employees may elect to participate in the ESPP during the 10-day period immediately preceding a related purchase period, which we refer to as an “election period.” The ESPP provides for six-month offerings, which we refer to as “purchase periods,” beginning each January 1 and July 1. Shares are purchased on the first business day following the end of a purchase period.
Payroll Deductions; Cash Contributions; Participation
Eligible employees may elect to contribute to the ESPP via (a) payroll deductions equal to a whole percentage or dollar amount of base salary with a minimum payroll deduction per pay period of $10 or (b) cash contributions. The maximum contributions that a participant can make for purchases under the ESPP for any calendar year is the lesser of (a) ten percent (10%) of such participant’s base salary for such calendar year, or (b) $25,000. Cash contributions must be paid prior to the last ten (10) business days of the related purchase period (such 10-day period, a “valuation period”). The ESPP does not provide for or permit BXP or any participating employer to match contributions of an eligible employee or otherwise contribute any funds to the ESPP.
BXP does not maintain a separate account or trust fund to hold funds received under the ESPP, and all funds received by BXP under the ESPP are included in our general funds and may be used for any corporate purpose. No interest accrues for the benefit of eligible employees on contributions pending purchase of shares of common stock.
Purchase of Stock; Purchase Price
As of the last day of each purchase period, each participant’s accumulated payroll deductions and/or cash contribution are used to purchase whole and fractional shares of our common stock. The purchase price per share will equal 85% of the average closing prices as reported on the NYSE for a share of our common stock during the related valuation period. Purchases will be made in whole shares and in any fraction of a whole share (computed to the number of decimal places set by the Plan Administrator) which can be purchased with the remaining balance of the participant’s contributions.
BXP / 2024 Proxy Statement 129

/Proposal 3
Holding Period
In general, if an employee is no longer a participant on a purchase date, we will refund (without interest) the amount of the employee’s accumulated payroll deductions. If a participant sells, exchanges, assigns, encumbers, alienates, transfers, pledges or otherwise disposes of shares of our common stock issued under the ESPP within one year of the related purchase date, the participant must pay to BXP an amount equal to the product of (a) the difference between (i) the average of the ten (10) closing prices for a share of our common stock during the related valuation period for such purchase period and (ii) the purchase price for such purchase period, and (b) the number of such shares sold, exchanged, assigned, encumbered, alienated, transferred, pledged or otherwise disposed of by the participant.
Terms of Participation; Withdrawal
A participant may reduce or stop payroll deductions at any time during a purchase period. A participant may only increase his or her payroll deductions or cash contributions with respect to subsequent purchase periods by enrolling within the related election period. A participant may also withdraw all or any part of his or her contributions (without interest) at any time prior to the related valuation period without affecting such participant’s eligibility to participate in future purchase periods. If a participant withdraws all of his or her contributions during a purchase period, that participant may not again participate in the same purchase period but may enroll in subsequent purchase periods. A participant’s withdrawal will be effective as soon as practicable following receipt of the participant’s notice of withdrawal.
Term; Amendments and Termination
The ESPP will continue until terminated by our Board of Directors. Our Board of Directors may, in its discretion, at any time, terminate or amend the ESPP. Upon termination of the ESPP, we will refund all amounts contributed by participating employees.
New Plan Benefits
Since participation in the ESPP is voluntary, the benefits or amounts that will be received by or allocated to any individual or group of individuals under the ESPP in the future are not determinable.
Summary of Federal Income Tax Consequences
The following is only a summary of the United States federal income tax laws and regulations applicable to an employee and us with respect to an employee’s participation in the ESPP. This summary does not purport to be a complete description of all federal income tax implications of participation in the ESPP, nor does it discuss the income tax laws of any municipality, state or foreign country in which an employee may reside or otherwise be subject to tax.
The ESPP is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. For federal income tax purposes, a participant generally will not recognize taxable income on the grant of a purchase right under the ESPP, nor will BXP be entitled to any deduction at that time. Upon the purchase of common stock under the ESPP, a participant will recognize ordinary income, and BXP will be entitled to a corresponding deduction, in an amount equal to the difference between the fair market value of the shares of common stock on the purchase date (i.e., the first business day following the purchase period) and the purchase price paid for the shares. Upon the subsequent sale of the shares acquired under the ESPP, the participant will recognize capital gain or loss (long-term or short-term, depending on how long the shares were held following the date they were purchased by the participant prior to disposing of them). A capital gain or loss will be long-term if the participant’s holding period is more than twelve (12) months, or short-term if the participant’s holding period is twelve (12) months or less.
Vote Required
The affirmative vote of a majority of shares of common stock present in person or represented by proxy at the meeting and entitled to vote on this proposal is required for the approval of the Fourth Amendment. Abstentions shall be included in determining the number of shares present and entitled to vote on the proposal, thus having the effect of a vote against the proposal. Broker non-votes are not counted in determining the number of shares present and entitled to vote and will therefore have no effect on the outcome.

Proposal 4 / Ratification of Appointment of Independent Registered Public Accounting Firm
Proposal
The Audit Committee of the Board of Directors is directly responsible for the appointment, compensation, retention and oversight of the independent registered public accounting firm retained to audit our consolidated financial statements. The Audit Committee has selected and appointed PricewaterhouseCoopers LLP as our independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2024. PricewaterhouseCoopers LLP has audited our consolidated financial statements continuously since our initial public offering in June 1997. In order to ensure continuing auditor independence, the Audit Committee periodically considers whether there should be a regular rotation of the independent registered public accounting firm. Further, in conjunction with the mandated rotation of the PricewaterhouseCoopers LLP’s lead engagement partner, the Audit Committee and its Chair were directly involved in the selection of PricewaterhouseCoopers LLP’s lead engagement partner. The members of the Audit Committee believe that the continued retention of PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm is in the best interests of BXP and its stockholders.
Although ratification by stockholders is not required by law or our By-laws, the Audit Committee believes that submission of its selection to stockholders is a matter of good corporate governance. Even if the appointment is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time if the Audit Committee believes that doing so would be in the best interests of BXP and its stockholders. If our stockholders do not ratify the appointment of PricewaterhouseCoopers LLP, the Audit Committee will consider that fact, together with such other factors it deems relevant, in determining its next selection of independent auditors.
We expect that a representative of PricewaterhouseCoopers LLP will attend the 2024 annual meeting of stockholders, will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.

Audit and Non-Audit Services Pre-Approval Policy
SEC rules require the Audit Committee to pre-approve all audit and non-audit services provided by our independent registered public accounting firm. In this regard, our Audit Committee adopted a policy concerning the pre-approval of these services to be provided by PwC, our independent registered public accounting firm. The policy requires that all services provided by PwC to us, including audit, audit-related, tax and other services, must be pre-approved by the Audit Committee. In some cases, pre-approval is provided by the full Audit Committee for up to a year, relates to a particular category or group of services and is subject to a particular budgeted maximum. In other cases, specific pre-approval is required. The Audit Committee has delegated authority to the Chair of the Audit Committee to pre-approve additional services, and any such pre-approvals must then be communicated to the full Audit Committee.
The Audit Committee approved all audit and non-audit services provided to us by PwC during the 2022 and 2023 fiscal years, and none of the services described above were approved pursuant to Rule 2-01(c)(7)(i)(c) of Regulation S-X, which relates to circumstances where the Audit Committee pre-approval requirement is waived.
Vote Required
The affirmative vote of a majority of shares of common stock present in person or represented by proxy at the meeting and entitled to vote on this proposal is required for the ratification of the appointment of PwC. Abstentions shall be included in determining the number of shares present and entitled to vote on the proposal, thus having the effect of a vote against the proposal. Broker non-votes, if any, are not counted in determining the number of shares present and entitled to vote and will therefore have no effect on the outcome.

Other Matters
Certain Relationships and Related Person Transactions
The Board of Directors has adopted a Related Person Transaction Approval and Disclosure Policy for the review and approval of any related person transaction. This written policy provides that all related person transactions must be reviewed and approved by a majority of the independent directors of our Board of Directors in advance of us or any of our subsidiaries entering into the transaction; provided that, if we or any of our subsidiaries enters into a transaction without recognizing that such transaction constitutes a related person transaction, the approval requirement will be satisfied if such transaction is promptly reviewed, approved and ratified by a majority of the independent directors of our Board of Directors. If any related person transaction is not approved or ratified by a majority of the independent directors of our Board, then to the extent permitted under applicable law, management shall use all reasonable efforts to amend, cancel or rescind the transaction. In addition, any related person transaction previously approved by a majority of the independent directors of our Board or otherwise already existing that is ongoing in nature shall be reviewed by a majority of the independent directors of our Board annually to ensure that such related person transaction has been conducted in accordance with the previous approval granted by such independent directors, if any, and remains appropriate.
The term “related person transaction” refers to a transaction required to be disclosed by us pursuant to Item 404 of Regulation S-K (or any successor provision) promulgated by the SEC other than a transaction for which an obligation to disclose under Item 404 of Regulation S-K (or any successor provision) arises solely from the fact that a beneficial owner of more than 5% of a class of the Company’s voting securities (or an immediate family member of any such beneficial owner) has an interest in the transaction. For purposes of determining whether disclosure is required, a related person will not be deemed to have a direct or indirect material interest in any transaction that is deemed to be immaterial (or would be deemed immaterial if such related person was a director) for purposes of determining director independence pursuant to the Company’s categorical standards of director independence. Please refer to the categorical standards under “Proposal 1 / Election of Directors—Director Independence” beginning on page 23.
Effective September 1, 2021, we leased approximately 2,700 square feet of office space to Retromer Therapeutics Corp., a start-up company of which Mr. Klein, our Lead Independent Director, is the Chief Executive Officer. The lease expired on December 31, 2023. Retromer made aggregate payments to BXP of approximately $264,000 during the year ended 2023.
In January 2018, Mr. Ritchey’s brother became an employee of a real estate firm with which the Company has entered into a contract for services. Since January 1, 2023, the Company has paid this real estate firm approximately $560,000. The Company terminated its contract with this real estate firm in 2023. Mr. Ritchey is the Senior Executive Vice President of BXP. The Company believes the terms of the related agreement were comparable to similar arrangements with other brokers in relevant markets.
We are partners with affiliates of Norges Bank Investment Management in joint ventures that own Times Square Tower, 601 Lexington Avenue, 100 Federal Street, Atlantic Wharf Office, 290 Binney Street and 300 Binney Street. Based on a Schedule 13G/A filed with the SEC on February 14, 2023, Norges Bank (The Central Bank of Norway), an affiliate of Norges Bank Investment Management, is the beneficial owner of more than 5% of our common stock.
We lease office space at our Santa Monica Business Park property to an entity that was acquired by an affiliate of BlackRock, Inc. in August 2018. Based on a Schedule 13G/A filed with the SEC on January 23, 2024, BlackRock is the beneficial owner of more than 5% of our common stock. Since January 1, 2023, the BlackRock affiliate paid the Company approximately $1,390,024 in lease payments.

Stockholders Entitled to Vote
If you were a stockholder of record as of the close of business on March 27, 2024, you are entitled to receive notice of the 2024 annual meeting and to vote the shares of BXP common stock held as of the close of business on the record date. Each stockholder is entitled to one vote for each share of common stock held as of the close of business on the record date. Holders of common units, LTIP units and deferred stock units are not entitled to vote those securities on any of the matters presented at the 2024 annual meeting.
Attending the Annual Meeting
All holders of record of BXP common stock at the close of business on the record date, or their designated proxies, are authorized to attend the 2024 annual meeting. Each stockholder and proxy will be asked to present a valid government-issued photo identification, such as a driver’s license or passport, before being admitted. If you are not a stockholder of record but you hold your shares in “street name” (i.e., your shares are held in an account maintained by a broker, bank or other nominee), then you should provide proof of beneficial ownership as of the record date, such as an account statement reflecting your stock ownership as of the record date, a copy of the voting instruction card provided by your broker, bank or other nominee, or other similar evidence of ownership. We reserve the right to determine the validity of any purported proof of beneficial ownership. If you do not have proof of ownership, you may not be admitted to the annual meeting. Cameras, recording devices and other electronic devices will not be permitted, and attendees may be subject to security inspections and other security precautions.

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 2024 annual meeting. As of the record date, there were 157,049,172 shares of common stock outstanding and entitled to vote at the 2024 annual meeting. Each share of common stock outstanding on the record date is entitled to one vote on each matter properly submitted at the annual meeting and, with respect to the election of directors, one vote for each director to be elected. Abstentions or “broker non-votes” (i.e., shares represented at the meeting held by brokers, banks or other nominees, as to which the proxy has been properly executed but instructions have not been received from the beneficial owners or persons entitled to vote such shares and with respect to

/Information About the Annual Meeting
Voting by Proxy for Shares Registered in Street Name
If your shares of common stock are held in street name, then you will receive instructions from your broker, bank or other nominee that you must follow in order to have your shares of common stock voted. Pursuant to the NYSE rules, if you do not give instructions to your broker, bank or other nominee, it will still be able to vote your shares with respect to certain “discretionary” items, but will not be allowed to vote your shares with respect to certain “non-discretionary” items. The ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm (proposal 4) is considered to be a discretionary item under the NYSE rules and your broker, bank or other nominee will be able to vote on that item even if it does not receive instructions from you. The election of directors (proposal 1), the non-binding, advisory vote on NEO compensation (proposal 2) and the vote on the Fourth Amendment to the ESPP (proposal 3) are considered non-discretionary items. If you do not instruct your broker, bank or other nominee how to vote your shares with respect to these non-discretionary items, it may not vote with respect to these proposals and those votes will be counted as broker non-votes. We strongly encourage you to submit your proxy with instructions and exercise your right to vote as a stockholder.
Revoking Proxy Instructions
You may revoke your proxy at any time before it has been exercised by:
filing a written revocation with the Secretary of Boston Properties, Inc., 800 Boylston Street, Suite 1900, Boston, Massachusetts 02199-8103;
submitting a new proxy by telephone, Internet or proxy card after the time and date of the previously submitted proxy; or
attending the annual meeting and voting by ballot at the annual meeting.
If you are a stockholder of record as of the record date and you attend the 2024 annual meeting, you may vote in person whether or not a proxy has been previously given, but your presence (without further action) at the annual meeting will not constitute revocation of a previously given proxy.
Accessing BXP's Proxy Materials Electronically

Householding
If you and other residents at your mailing address own shares of common stock in street name, your broker, bank or other nominee may have sent you a notice that your household will receive only one annual report, Notice of Internet Availability of Proxy Materials, notice of annual meeting and/or proxy statement. This procedure, known as “householding,” is intended to reduce the volume of duplicate information stockholders receive and also reduce our printing and postage costs. Under applicable law, if you consented or were deemed to have consented, your broker, bank or other nominee may send one copy of our annual report, Notice of Internet Availability of Proxy Materials, notice of annual meeting and/or proxy statement to your address for all residents that own shares of common stock in street name. If you wish to revoke your consent to householding, you must contact your broker, bank or other nominee. If you are receiving multiple copies of our annual report, Notice of Internet Availability of Proxy Materials, notice of annual meeting and/or proxy statement, you may be able to request householding by contacting your broker, bank or other nominee.
