All stockholders of record of our common stock at the close of business on April 24, 2024, or the Record Date, are entitled to receive the Notice and to vote their shares at the Annual Meeting. As of that date, shares of our common stock were outstanding. Each share is entitled to one vote on each matter properly brought to the meeting.

VOTING METHODS

You may cast your vote in any of the following ways:

HOW YOUR SHARES WILL BE VOTED

In each case, your shares will be voted as you instruct. If you return a signed card, but do not provide voting instructions, your shares will be voted FOR each of the proposals. If you are the record holder of your shares, you may revoke or change your vote any time before the proxy is exercised. To do so, you must do one of the following:

•

Vote over the Internet or by telephone as instructed above. Only your latest Internet or telephone vote is counted. You may not revoke or change your vote over the Internet or by telephone after 11:59 p.m., Eastern Time, on June 19, 2024.

Deadline for Voting. The deadline for voting by telephone or Internet, other than by virtually attending the Annual Meeting, is 11:59 p.m. Eastern Time on June 19, 2024. If you are a registered stockholder and virtually attend the

TABLE OF CONTENTS

GENERAL INFORMATION ABOUT THE MEETING

Annual Meeting, you may deliver your vote online during the Annual Meeting. "Street name" stockholders who wish to vote at the Annual Meeting will need to obtain a proxy form from the institution that holds their shares.

BROKER VOTING AND VOTES REQUIRED FOR EACH PROPOSAL

If your shares are held in a stock brokerage account or by a bank or other holder of record, you are considered the "beneficial owner" of shares held in street name. The Notice has been forwarded to you by your broker, bank or other holder of record who is considered the stockholder of record of those shares. As the beneficial owner, you may direct your broker, bank or other holder of record on how to vote your shares by using the proxy card included in the materials made available or by following their instructions for voting on the Internet.

A broker non-vote occurs when a broker or other nominee that holds shares for another does not vote on a particular item because the nominee does not have discretionary voting authority for that item and has not received instructions from the beneficial owner of the shares. The following table summarizes how votes withheld, broker non-votes and abstentions are treated with respect to our proposals:

For the purpose of establishing a quorum, votes withheld, abstentions, including brokers holding customers' shares of record who cause abstentions to be recorded at the meeting, and broker non-votes count toward the quorum.

TABLE OF CONTENTS

BOARD OF DIRECTORS

Our Board has nominated Kimberly Blackwell, M.D., Joseph Jimenez and Brent Pfeiffenberger, Pharm.D. for election as Class III directors at our Annual Meeting to hold office until our 2027 Annual Meeting of Stockholders.

Our Board is the Company's ultimate decision-making body, except with respect to those matters reserved to the stockholders. Our Board selects the members of our senior management team, who in turn are responsible for our day-to-day operations. Our Board acts as an advisor and counselor to senior management and oversees their performance.

Our Board consists of directors divided into three classes, with each class holding office for a three-year term. Kimberly Blackwell, M.D., Joseph Jimenez and Brent Pfeiffenberger, Pharm.D., current Class III directors, have been nominated by our Board for election at the Annual Meeting for three-year terms that will expire at the 2027 Annual Meeting of Stockholders and until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. Each of the nominees has agreed to be named and to serve, and we expect each nominee to be able to serve if elected. If any nominee is unable to serve, the Nominating and Corporate Governance Committee will recommend to our Board a replacement nominee. The Board may then designate the other nominee to stand for election. If you voted for the unavailable nominee, your vote will be cast for his or her replacement.

BOARD STRUCTURE AND COMPOSITION

The Nominating and Corporate Governance Committee is responsible for recommending the composition and structure of our Board and for developing criteria for Board membership. The Nominating and Corporate Governance Committee regularly reviews director competencies, qualities and experiences, with the goal of ensuring that our Board is comprised of an effective team of directors who function collegially and who are able to apply their experience toward meaningful contributions to our business strategy and oversight of our performance, risk management, organizational development and succession planning.

Our Second Amended and Restated Bylaws, or Bylaws, provide that the number of members of our Board shall be fixed by the Board from time to time. Our Board is currently fixed at eight members. Our Board is divided into three classes with staggered three-year terms. The Nominating and Corporate Governance Committee is responsible for identifying individuals that it believes are qualified to become Board members.

CRITERIA FOR BOARD MEMBERSHIP

The Nominating and Corporate Governance Committee has identified certain criteria that it will consider in identifying director nominees. Important general criteria and considerations for Board membership include:

	GENERAL CRITERIA
	Proven integrity Capability to fairly and equally act in the best interest of our stockholders Prior or current leadership experience, including within the biotechnology and biopharmaceutical spheres Broad experience, diverse perspectives, and the ability to exercise sound judgment, and a judicious and critical temperament that will enable objective appraisal of management's plans and programs Willingness and ability to devote sufficient time to Board responsibilities Diversity with respect to gender, age, race, ethnicity, background, professional experience and perspectives

The Nominating and Corporate Governance Committee also considers, on an ongoing basis, the background, experience and skills of the incumbent directors that are important to our current and future business needs, and evaluates the experience and skills that would be valuable in new Board members.

SELECTION OF CANDIDATES

Director Skill Set Considerations; Use of Skills Matrix

To assist with determining the needs of the Board, the Nominating and Corporate Governance Committee utilizes a skills matrix for the purpose of recruiting and selecting Board candidates. The expertise and experience included

Notice of Annual Meeting of Stockholders and 2024 Proxy Statement | 4

TABLE OF CONTENTS

BOARD OF DIRECTORS

in the skills matrix are tied to our strategic goals, and the intent of the skills matrix is to ensure that the directors collectively possess qualities that facilitate effective oversight of our strategic plans. While the matrix is useful for determining the collective skills of the Board as a whole, it is not a comparative measure of the value of each individual director; a director with more focused experience could nonetheless contribute broadly and effectively. The Nominating and Corporate Governance Committee also considers a wide range of additional factors including other positions the director or candidate holds, including other boards of directors on which he or she serves, and the independence of each director and candidate, to ensure that a substantial majority of the Board is independent. The matrix below displays the current Board's balance.

Director Skills Matrix

Potential Director Candidates

On an ongoing basis, the Nominating and Corporate Governance Committee considers potential director candidates identified on its own initiative, as well as candidates referred or recommended to it by other directors, members of management, search firms, stockholders and others (including individuals seeking to join the Board). Stockholders who wish to recommend candidates may contact the Nominating and Corporate Governance Committee in the manner described in "Stockholder Communications to the Board." Stockholder nominations must be made according to the procedures required under our Bylaws and described in this Proxy Statement under the heading "Requirements for Submission of Stockholder Proposals for Next Year's Annual Meeting." Stockholder-recommended candidates and stockholder nominees whose nominations comply with these procedures and who meet the criteria referred to above will be evaluated by the Nominating and Corporate Governance Committee in the same manner as the Board's nominees.

BOARD OF DIRECTORS

BOARD DIVERSITY

Board diversity and inclusion is critical to the our success. While we do not have a formal policy on Board diversity, the Board is committed to building a Board that consists of the optimal mix of skills, expertise, and diversity capable of effectively overseeing the execution of our business and meeting our evolving needs, with diversity reflecting gender, age, race, ethnicity, background, professional experience and perspectives. The Nominating and Corporate Governance Committee considers the value of diversity on the Board in evaluating director nominees. Accordingly, the Nominating and Corporate Governance Committee's evaluation of director nominees includes consideration of their ability to contribute to the diversity of personal and professional experiences, opinions, perspectives and backgrounds on the Board.

CURRENT DIVERSITY BREAKDOWN

As presently constituted, the Board represents a deliberate mix of members who have a deep understanding of our business as well as members who have different skill sets and points of view. The listing requirements of the Nasdaq Stock Market LLC, or Nasdaq, require each listed company to have, or explain why it does not have, two diverse directors on the board, including at least one diverse director who self-identifies as female and at least one diverse director who self-identifies as an underrepresented minority or LGBTQ+, or for smaller reporting companies, two female directors. Our current board composition is in compliance with this requirement. We are particularly proud of the diversity on our Board, which includes three Board members who self-identify as diverse, including our Chairman of the Board, Chair of the Nominating and Corporate Governance Committee and Chair of the Audit Committee.

The matrix below provides certain highlights of the composition of our Board members based on self-identification. Each term used above and in the matrix below has the meaning given to it in Nasdaq Listing Rule 5605(f).

BOARD OVERSIGHT OF COMPANY CULTURE AND ENVIRONMENTAL, SOCIAL AND GOVERNANCE HIGHLIGHTS

Our Board is committed to fostering a strong culture of compliance and ethical conduct and has structured its committees and their activities to support its commitment. Our Board supports management's promotion of a corporate culture of integrity, ethical behavior and compliance with laws and regulations and for ensuring that our culture and strategy are aligned. Our Board expects all directors, as well as officers and employees, to conduct themselves in a manner consistent with our Code of Business Conduct and Ethics, or the Code of Conduct, and our values.

Separate Chairperson of the Board and Chief Executive Officer: The offices of Chief Executive Officer and Chairperson of the Board are separated, which reinforces the independence of the Board from management and creates an environment that encourages objective oversight of management's performance, which we believe enhances the effectiveness of our Board as a whole.

•

Independent Committees: Each of our Board committees consist entirely of independent directors.

•

Regularly Held Executive Sessions:The independent directors of our Board meet separately in executive session on a regular basis to discuss matters relating to the Company and the Board, without members of the management team present.

•

Code of Conduct: All of our directors, officers and employees are subject to the Code of Conduct, which is available on our website at www.centurytx.com.

•

Human Capital Management: We are committed to the health and welfare of our employees. We support the development of our employees with a competitive compensation and benefits package, internal advancement, and individualized development opportunities.

•

Diversity and Inclusion: We strive to create a workplace culture that supports a diverse, multi-cultural workforce, treats individuals fairly, and provides an inclusive environment where everyone can bring their whole self to work and feel supported in reaching their full potential. We are embarking on an organization-wide learning initiative to ensure we each have the competence and confidence to contribute to this culture. The executive committee, senior leadership, people leaders and colleagues have engaged in a highly interactive Unconscious Bias Training to identify and adjust for bias at the individual and organizational level. Our goal through this initiative is to empower our team to grow self-awareness, collaborate inclusively, and ultimately support higher performance. As of March 2023, Century had a diverse workforce consisting of 49% female employees, consistent with data from the 2022 annual report of the Biotechnology Innovation Organization. In addition, 35% percent of the workforce identifies as a race/ethnicity other than white.

TABLE OF CONTENTS

CORPORATE GOVERNANCE AND RISK MANAGEMENT

We are committed to good corporate governance and integrity in our business dealings. We believe that strong corporate governance practices that provide meaningful rights to our stockholders and ensure Board and management accountability are key to our relationship with our stockholders. We strive to have regular, constructive conversations with our stockholders to better understand our stockholders' priorities and perspectives.

Our governance practices are documented in our Second Amended and Restated Certificate of Incorporation, or our Certificate of Incorporation, our Bylaws, our Code of Conduct, our Corporate Governance Guidelines and the charters of the committees of the Board. Aspects of our governance documents are summarized below. You can find our charters for each committee of our Board and our Code of Conduct on our website at investors.centurytx.com/corporate-governance/documents-and-charters.

BOARD INDEPENDENCE

Our Board has determined that, with the exception of Dr. Pfeiffenberger, and our former President and Chief Executive Officer, Dr. Osvaldo Flores, each of our directors, including each former director who served as a member of the Board during the last fiscal year, is an "independent director," as defined under the rules of Nasdaq. In making such determination, the Board considered the relationships that each such non-employee director has with the Company and all other facts and circumstances that the Board deemed relevant in determining their independence, including the beneficial ownership of our common stock by each non-employee director. Dr. Osvaldo Flores, our former President and Chief Executive Officer, served on our Board from 2022 until 2023 and was not an independent director. Dr. Flores resigned from our Board on April 11, 2023. Our independent directors generally meet in executive session at each regularly scheduled Board meeting.

BOARD LEADERSHIP STRUCTURE

Our Board does not have a formal policy with respect to the separation of the offices of Chief Executive Officer and Chairman of the Board. It is the Board's view that rather than having a rigid policy, the Board, with the advice and assistance of the Nominating and Corporate Governance Committee, and upon consideration of all relevant factors and circumstances, will determine, as and when appropriate, whether the two offices should be separate. Currently, our leadership structure separates the offices of Chief Executive Officer and Chairman of the Board. Our Board believes that the separation of the positions of Chief Executive Officer and Chairman of the Board reinforces the independence of the Board from management, creates an environment that encourages objective oversight of management's performance and enhances the effectiveness of our Board as a whole.

BOARD COMMITTEES

Our Board has established various Committees to assist in discharging its duties: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Each member of our Committees is an independent director as that term is defined by the SEC and Nasdaq. The primary responsibilities of each of the Committees and the Committee memberships are provided below under the section entitled "Board Attendance, Committee Meetings and Committee Membership."

Each of the Committees has the authority, as its members deem appropriate, to engage legal counsel or other experts or consultants in order to assist the Committee in carrying out its responsibilities.

RISK MANAGEMENT

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings, and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the Board at regular Board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks.

Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address the

risks inherent in their respective areas of oversight. While our Board is responsible for monitoring strategic risk exposure, our Audit Committee oversees management of financial reporting, compliance, cybersecurity and litigation risks, as well as the steps management has taken to monitor and control such exposures. Our Nominating and Corporate Governance Committee manages risks associated with the independence of our Board, potential conflicts of interest and the effectiveness of our Board and our Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation policies, plans and arrangements and the extent to which those policies or practices increase or decrease risks for our company.

EVALUATING BOARD EFFECTIVENESS

The Board, led by the Nominating and Corporate Governance Committee, is committed to continuous improvement and believes annual self-evaluations are an important tool for evaluating effectiveness. It has established and conducted an annual self-evaluation of the Board, which is presented by the Chairperson of the Nominating and Corporate Governance Committee to the Board for discussion. In addition, each committee conducts an annual self-assessment in a review process similar to that used by the Board. Below is a graphic depicting the Board and Nominating and Corporate Governance Committee annual cycle in evaluating Board effectiveness.

CODE OF BUSINESS CONDUCT AND ETHICS

We maintain a written Code of Conduct that applies to all of our directors, officers, and employees. The Code of Conduct covers fundamental ethics and compliance-related principles and practices such as accurate accounting records and financial reporting, avoiding conflicts of interest, compliance with insider trading laws, the protection and use of our property and information, and compliance with legal and regulatory requirements. The Code of Conduct is posted on our website at investors.centurytx.com/corporate-governance/documents-and-charters. We intend to disclose any amendments to our code of business conduct and ethics, or waivers of its requirements, on our website to the extent required by the applicable rules and exchange requirements.

CORPORATE GOVERNANCE AND RISK MANAGEMENT

DIRECTOR ORIENTATION AND CONTINUING EDUCATION

Our director orientation programs familiarize new directors with the Company's businesses, financial position, facilities, strategies, and policies, and assist new directors in developing the skills and knowledge required for their service on the Board. From time to time, management advises, or invites outside experts to attend Board meetings to advise the Board on its responsibilities, management's responsibilities, developments relevant to corporate governance and best corporate practices. Additionally, Board members may attend, and are encouraged to attend, accredited director education programs at the Company's expense.

CORPORATE GOVERNANCE GUIDELINES

We have a written set of Corporate Governance Guidelines that are designed to help ensure effective corporate governance of our Company. Our Corporate Governance Guidelines cover topics including, but not limited to, the size and composition of the Board, Board membership criteria, director qualifications and duties, Board committees, director compensation and director communications with third parties. Succession planning for the Board is critical to our success. Our goal is to achieve a Board that provides effective oversight of the Company through the appropriate balance of diversity of perspectives, experience, expertise and skills. Our Corporate Governance Guidelines are reviewed periodically by the Nominating and Corporate Governance Committee, which recommends any proposed changes to our Board for approval. Our Corporate Governance Guidelines can be found on our website at www.investors.centurytx.com/corporate-governance/documents-and-charters.

Notice of Annual Meeting of Stockholders and 2024 Proxy Statement | 24

TABLE OF CONTENTS

EXECUTIVE COMPENSATION

Base salary

The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role, responsibilities, and contributions. Each NEO's initial base salary was specified in his or her employment agreement, as described below, and is reviewed (and, if applicable, adjusted) from time to time by our Board or Compensation Committee, as applicable. In 2023, the annual base salary rates for our NEOs were $625,000 for Dr. Pfeiffenberger (pro-rated), $474,800 for Dr. Russotti, which was subsequently increased to $614,092.50 upon his appointment to interim Chief Executive Officer for the period he served as interim Chief Executive Officer (for more information, see below for the description of the Russotti Side Letter, as defined below), $614,092.50 for Dr. Flores, $482,700 for Dr. Diem, which was subsequently increased to $500,000 upon his transition from Chief Business Officer to Chief Financial Officer in May 2023, and $496,500 for Dr. Farid.

Annual Incentive Opportunities

Each of our NEOs' annual non-equity incentive opportunity is expressed as a percentage of base salary that can be earned based on the achievement of predetermined corporate and individual performance objectives. The 2023 annual bonus opportunities for Dr. Pfeiffenberger and Dr. Farid were targeted at 55% and 40% of their respective base salaries. Dr. Russotti's annual bonus opportunity was increased from 40% to 45% in connection with his appointment to interim Chief Executive Officer (for more information, see below for the description of the Russotti Side Letter, as defined below).

For 2023, all NEOs were eligible to earn their annual cash incentives pursuant to the achievement of corporate and/or individual performance goals approved by our Board. These goals primarily related to pipeline and platform development, financing, operations, business development, intellectual property and increasing external visibility. The Board determined that the 2023 corporate goals were achieved at 85%. Following a review of 2023 performance, our Compensation Committee approved, and, in the case of Dr. Pfeiffenberger, our Compensation Committee recommended and our Board approved, 2023 annual cash incentive payouts to each of Dr. Pfeiffenberger, Dr. Russotti, and Dr. Farid equal to $24,348.96, $275,000 and $166,724, respectively, in each case representing 85% of the target cash incentive for each such NEO. Pursuant to their respective severance agreements described below, Dr. Flores and Dr. Diem were not eligible to receive annual cash incentive payouts for 2023.

Long Term Equity Incentives

Annual Equity Grants

Our equity-based incentive awards are designed to align the interests of our stockholders with those of our NEOs.

In 2023, our Compensation Committee approved equity grants to our non-Chief Executive Officer NEOs in the form of 100% options, or a split between 75% options and 25% restricted stock units, at the option of the grantee. We made equity grants to (i) each of Dr. Diem and Dr. Farid, consisting of (a) options to purchase 131,250 shares of common stock and (b), and (ii) to Dr. Russotti consisting of an option to purchase 175,000 shares of common stock.

Other Benefits

Our NEOs are eligible for the same welfare benefits that are generally available to all of our salaried employees, including health, dental, life, vision, and disability insurance.

In addition, we maintain, and the NEOs are eligible to participate in, a 401(k) plan that provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis and under which we make safe harbor matching employer contributions. We match 100% of each participating employee's contributions (up to the first 3% of eligible compensation) and 50% of the participating employee's contributions (for the next 2% of eligible compensation), and participants are always fully vested in these employer matching contributions. For 2023, the Internal Revenue Service, or IRS, limit on eligible compensation for this purpose was $330,000. Employees' pre-tax contributions are allocated to each participant's individual account and are then invested in selected investment alternatives according to the participant's directions. The 401(k) plan is intended to be qualified under Section 401(a) of the Internal Revenue Code.

The 2021 Plan contains an "evergreen" provision, pursuant to which, on or about January 1 each year, the maximum number of shares reserved for issuance under the 2021 Plan is increased by a number equal to the lesser of (i) 5% of the shares of common stock issued and outstanding on the last day of the immediately preceding fiscal year and (ii) such smaller number of shares of common stock as determined by the Board. The 2021 ESPP provides that the number of shares reserved and available for issuance will automatically increase each January 1, beginning on January 1, 2022, by the lesser (a) 1,128,42 shares of common stock, (b) 1% of the shares of common stock outstanding on the final day of the immediately preceding calendar year, and (c) such smaller number of shares as determined by the Board. The number in the table does not include the increases from January 1, 2024.

(3)

Does not include purchase rights accruing under the 2021 ESPP as of December 31, 2023, because the purchase rights (and, therefore, the number of shares to be purchased) will not be determined until the end of the purchase period on June 30, 2024. Subject to the number of shares remaining in the share reserve, the maximum number of shares purchasable by any participant in the 2021 ESPP during the purchase period beginning January 1, 2024 and ending on June 30, 2024 is 5,000.

(4)

Includes shares available for future issues under the 2021 ESPP and 2021 Plan. As of December 31, 2023, 1,019,241 shares of common stock were available for issuance under the 2021 ESPP and 3,128,244 shares of common stock were available for issuance under the 2021 Plan.

PROPOSAL 2: RATIFICATION OF APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2024

The Audit Committee of the Board has appointed and engaged EY to serve as our independent registered public accounting firm to audit the consolidated financial statements of the Company and our subsidiary for the 2024 fiscal year, and to perform audit-related services. EY has served as our independent registered public accounting firm since 2019.

Stockholders are hereby asked to ratify the Audit Committee's appointment of EY as our independent registered public accounting firm for the 2024 fiscal year.

The Audit Committee is solely responsible for selecting our independent auditors. Although stockholder ratification of the appointment of EY to serve as our independent registered public accounting firm is not required by law or our organizational documents, the Board has determined that it is desirable to seek stockholder ratification as a matter of good corporate governance in view of the critical role played by independent registered public accounting firms in maintaining the integrity of financial controls and reporting. If the stockholders do not ratify the appointment of EY, the Audit Committee will reconsider its selection and whether to engage an alternative independent registered public accounting firm.

Representatives of EY are expected to virtually attend the Annual Meeting where they will be available to respond to appropriate questions and, if they desire, to make a statement.

PROPOSAL 3: APPROVAL OF AN AMENDMENT TO OUR SECOND AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OFFICERS OF THE COMPANY AS PERMITTED BY RECENT AMENDMENTS TO DELAWARE LAW

Background

We are incorporated in the State of Delaware. Recently, Delaware enacted legislation, effective August 1, 2022, that enables Delaware companies to limit the liability of certain officers in limited circumstances under Section 102(b)(7) of the Delaware General Corporation Law, or the DGCL. Amended DGCL Section 102(b)(7) only permits exculpation for direct claims brought by stockholders for breach of an officer's fiduciary duty of care, including class actions, but does not eliminate officers' monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. Furthermore, the limitation on liability does not apply to breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit.

Our Board believes it is important to provide protection from certain liabilities and expenses that may discourage prospective or current directors from accepting or continuing membership on corporate boards and prospective or current officers from serving corporations. In the absence of such protection, qualified directors and officers might be deterred from serving as directors or officers due to exposure to personal liability and the risk that substantial expense will be incurred in defending lawsuits, regardless of merit. In particular, the Board took into account the narrow class and type of claims that such officers would be exculpated from liability pursuant to amended DGCL Section 102(b)(7), the limited number of our officers that would be impacted, and the benefits the Board believes we would accrue providing exculpation in accordance with DGCL Section 102(b)(7), including, without limitation, the ability to attract and retain key officers and the potential to reduce litigation costs associated with frivolous lawsuits.

Our Board balanced these considerations with our corporate governance guidelines and practices and determined that it is advisable and in the best interests of us and our stockholders to amend our Certificate of Incorporation to adopt amended DGCL Section 102(b)(7) and extend exculpation protection to our officers in addition to our directors. We refer to this proposed amendment to our Certificate of Incorporation as the "Charter Amendment" herein.

Text of Proposed Charter Amendment

Our Certificate of Incorporation currently provides for the exculpation of directors, but does not include a provision that allows for the exculpation of officers. To ensure we are able to attract and retain key officers and in an effort to reduce litigation costs associated with frivolous lawsuits, we propose to amend our Certificate of Incorporation to add new Article XI, which would state:

"Article XI - Limitation of Liability

To the fullest extent permitted by the DGCL, an Officer (as defined below) of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as an officer of the Corporation, except for liability (a) for any breach of the Officer's duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for any transaction from which the Officer derived an improper personal benefit, or (d) arising from any claim brought by or in the right of the Corporation. If the DGCL is amended after the effective date of this Certificate to authorize corporate action further eliminating or limiting the personal liability of Officers, then the liability of an Officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. For purposes of this Article XI, "Officer" shall mean an individual who has been duly appointed as an officer of the Corporation and who, at the time of an act or omission as to which liability is asserted, is deemed to have consented to service of process to the registered agent of the Corporation as contemplated by 10 Del. C. § 3114(b).

Any amendment, repeal or modification of this Article XI by either of (i) the stockholders of the Corporation or (ii) an amendment to the DGCL, shall not adversely affect any right or protection existing at the time of such amendment, repeal or modification with respect to any acts or omissions occurring before such amendment, repeal or modification of a person serving as an Officer at the time of such amendment, repeal or modification."

Notice of Annual Meeting of Stockholders and 2024 Proxy Statement | 40

TABLE OF CONTENTS

ITEMS TO BE VOTED ON

The proposed Certificate of Amendment to the Certificate of Incorporation, or the Certificate of Amendment, reflecting the foregoing Charter Amendment is attached as Exhibit A to this Proxy Statement.

Reasons for the Proposed Charter Amendment

The Board believes it is appropriate for public companies in states that allow exculpation of officers to have exculpation clauses in their certificates of incorporation. The nature of the role of directors and officers often requires them to make decisions on crucial matters. Frequently, directors and officers must make decisions in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits or proceedings seeking to impose liability on the basis of hindsight, especially in the current litigious environment and regardless of merit. Limiting concern about personal risk would empower both directors and officers to best exercise their business judgment in furtherance of stockholder interests. We expect our peers to adopt exculpation clauses that limit the personal liability of officers in their certificates of incorporation, and failing to adopt the proposed Charter Amendment could impact our recruitment and retention of exceptional officer candidates that conclude that the potential exposure to liabilities, costs of defense and other risks of proceedings exceeds the benefits of serving as an officer to us.

For the reasons stated above, on March 13, 2024, the Board determined that the proposed Charter Amendment is advisable and in the best interest of us and our stockholders and authorized and approved the proposed Charter Amendment and directed that it be considered at the Annual Meeting. The Board believes the proposed Charter Amendment would better position us to attract top officer candidates and retain our current officers and enable the officers to exercise their business judgment in furtherance of the interests of the stockholders without the potential for distraction posed by the risk of personal liability.

Additionally, the Charter Amendment would align the protections for our officers with those protections currently afforded to our directors.

The proposed Charter Amendment is not being proposed in response to any specific resignation, threat of resignation or refusal to serve by any officer.

Timing and Effect of the Charter Amendment

If the proposed Charter Amendment is approved by our stockholders, it will become effective immediately upon the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, which we expect to file promptly after the Annual Meeting. Other than the proposed addition of Article XI, the remainder of our Certificate of Incorporation will remain unchanged after effectiveness of the Charter Amendment. If the proposed Charter Amendment is not approved by our stockholders, our Certificate of Incorporation will remain unchanged. In accordance with the DGCL, the Board may elect to abandon the proposed Charter Amendment without further action by the stockholders at any time prior to the effectiveness of the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, notwithstanding stockholder approval of the proposed Charter Amendment.

If a quorum is present, the affirmative vote of a majority of all of our issued and outstanding shares of common stock entitled to vote is required for approval of the proposed Charter Amendment. Abstentions and broker non-votes will have the effect of voting against this proposal.
