Our Director Nominees
You are being asked to vote on the election of Alessandro Riva, M.D. and Han Lee, Ph.D., M.B.A. as Class II directors, each to serve for a three-year term expiring at our 2029 Annual Meeting of Stockholders. The number of members of our Board of Directors, or the Board, is currently set at seven members and is divided into three classes, each of which has a three-year term. Class I consists of one director, Class II consists of three directors and Class III consists of three directors. In connection with our nomination process for the Annual Meeting, our Board has determined not to appoint Mr. Walbert to stand for re-election and his term on the Board, including his service on the Compensation Committee which he serves, will end effective as of the date of the Annual Meeting. As such, the Board will consist of six members and Class II will consist of two directors effective as of the date of the Annual Meeting. The Board’s decision does not reflect any concerns regarding Mr. Walbert’s performance or qualifications. We extend our gratitude and appreciation for Mr. Walbert for his service and contributions to us and our Board.
The term of office of our Class II directors expires at the Annual Meeting. We are nominating Alessandro Riva, M.D. and Han Lee, Ph.D., M.B.A. for election at our Annual Meeting to serve until the 2029 Annual Meeting of Stockholders and until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. Directors are elected by a plurality of the votes properly cast by our stockholders at the Annual Meeting. The two nominees receiving the most FOR votes (among votes properly cast online at the meeting or by proxy) will be elected. If no contrary indication is made, shares represented by executed proxies will be voted FOR the election of Alessandro Riva, M.D. and Han Lee, Ph.D., M.B.A. Each nominee has agreed to serve as a director if elected, and we have no reason to believe that any nominee will be unable to serve.

RECENT CORPORATE HIGHLIGHTS
•
In November 2025, we announced our plans to develop a beta islet program, CNTY-813, for Type 1 diabetes, or T1D. We are leveraging our deep expertise in selective iPSC differentiation to advance this program, engineered with Allo-Evasion™ 5.0, toward clinical evaluation subject to regulatory clearance. We have moved CNTY-813 into IND-enabling studies and anticipate submission of an IND application as early as 2026.
•
We also continue to make progress with IND-enabling studies for CNTY-308, a CD19-targeted CD4+/CD8+ αβ CAR-iT cell therapy functionally comparable to primary T cells and engineered with Allo-Evasion™ 5.0. CNTY-308 is being developed as a potential treatment for B-cell-mediated diseases. Following successful completion of these IND-enabling studies, and the receipt of requisite regulatory authorization, we expect to initiate clinical studies in 2026.
•
In November 2025, we also announced that we will prioritize clinical development activities for CNTY-101, a CAR-iNK cell therapy with six precision gene edits, in CARAMEL, a Phase 1/2 investigator sponsored trial, or IST, which is currently enrolling and dosing patients living with B-cell-mediated autoimmune diseases, led by Professors Georg Schett and Andreas Mackensen and is sponsored by the Friedrich-Alexander University Erlangen-Nürnberg. Investigators of the CARAMEL IST presented initial data in December 2025.
•
In December 2025, Han Lee, Ph.D., M.B.A., and Martin Murphy, Ph.D., were appointed to our Board. As part of their appointments, Dr. Lee serves as a member of the Audit and the Compensation Committees and Dr. Murphy serves as Chair of the Compensation Committee and a member of the Nominating and Corporate Governance Committee.

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:

BOARD OF DIRECTORS
|
|
Our Board has nominated Alessandro Riva, M.D., and Han Lee, Ph.D., M.B.A. for election as Class II directors at our Annual Meeting to hold office until our 2029 Annual Meeting of Stockholders.
Our Board is our 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. Alessandro Riva, M.D., Han Lee, Ph.D., M.B.A. and Timothy Walbert, are our current Class II directors whose terms expire at the Annual Meeting. The Board has nominated Alessandro Riva, M.D. and Han Lee, Ph.D., M.B.A. for election at the Annual Meeting for three-year terms that will expire at the 2029 Annual Meeting of Stockholders and until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. Mr. Walbert will not stand for re-election and his term will end effective as of the date of the Annual Meeting. 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 seven 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:

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

|
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.

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.

GOVERNANCE HIGHLIGHTS
The Board is committed to maintaining an optimal mix of skills, expertise and backgrounds to effectively oversee the execution of our strategy and meet our evolving needs, while bringing differing professional experiences and perspectives. 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 Nominating and Corporate Governance Committee considers the value of having differing professional experiences and perspectives 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 differing of personal and professional experiences, opinions and perspectives on the Board.
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. Our Board believes that a strong culture of integrity, ethics and compliance is fundamental to the conduct of our business, and is necessary for effective risk management, maintaining investor trust, and successful corporate governance.
We understand corporate responsibility is essential for good governance because it strengthens the accountability of our Board and management team. We view Environmental, Social and Governance, or ESG, initiatives as long-term value drivers for the Company and our stockholders. Our focus on and commitment to ESG is tied to our belief that achieving and sustaining business excellence goes hand-in-hand with strong corporate leadership and stewardship. Our Board is primarily responsible for overseeing our corporate strategy, which includes the oversight of ESG matters that impact our business and related risks. Though our current ESG initiatives are broad, we continue to focus on our people, culture and strong corporate governance. We are committed to advancing a series of new ESG initiatives and performance targets, which will evolve over time.
The following is a summary of our current corporate governance policies and practices:
•
Lead Independent Director: The offices of Chairperson of the Board (held by our Chief Executive Officer) and Lead Independent Director are separated, which reinforces the Board’s independence from management and creates an environment that encourages objective oversight of management’s performance.
•
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.
•
Talent 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.

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 Charter, 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, each of our directors 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. 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 does not separate the offices of Chief Executive Officer and Chairman of the Board. Our Board has determined in its judgment that the Company benefits from having a combined Chairman and Chief Executive Officer position at this time. Dr. Pfeiffenberger’s unique perspective and experience are valuable in setting the overall direction and business strategy for us.
Dr. Blackwell was appointed Lead Independent Director of our Board in March 2026. Our Board believes that the role of Lead Independent Director reinforces the Board’s independence from management and creates an environment that encourages objective oversight of management’s performance. The responsibilities of Lead Independent Director include presiding at executive sessions of independent directors and serving as a liaison between our Chief Executive Officer and Chairman of the Board, and our independent directors. Our Board periodically reviews its leadership structure and may make such changes in the future as it deems appropriate.
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.
Notice of Annual Meeting of Stockholders and 2026 Proxy Statement | 10
| |
CORPORATE GOVERNANCE AND RISK MANAGEMENT
|
|
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.

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 https://investors.centurytx.com/corporate-governance/documents-and-charters.

Notice of Annual Meeting of Stockholders and 2026 Proxy Statement | 21

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.
Effective March 1, 2025, the annual base salary rates for our NEOs were $643,800 for Dr. Pfeiffenberger, $562,400 for Dr. Russotti, $531,800 for Dr. Farid and $551,000 for Dr. Cowan.
Annual Incentive Opportunities
Each of our NEO’s 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 2025 annual bonus opportunities for Dr. Pfeiffenberger, Dr. Russotti, Dr. Farid and Dr. Cowan were targeted at 55%, 45%, 40% and 40% of their respective base salaries.
For 2025, 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, manufacturing, business development and financing. The Board determined that the 2025 corporate goals were achieved at 90% for Dr. Pfeiffenberger, Dr. Russotti and Dr. Cowan. Following a review of 2025 performance, our Compensation Committee approved, and, in the case of Dr. Pfeiffenberger, our Compensation Committee recommended and our Board approved, 2025 annual cash incentive payouts to each of Dr. Pfeiffenberger, Dr. Russotti and Dr. Cowan equal to $317,109.40, $226,658 and $201,008, respectively, in each case representing 90% of the target cash incentive for each such NEO. Dr. Farid was not eligible to receive an annual cash incentive for 2025 due to her departure, but was eligible to receive a prorated 2025 bonus, assuming target achievement, in connection with her termination.
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. Our Board or Compensation Committee, as applicable, approves equity grants to NEOs under our 2021 Plan. In March 2025, our Compensation Committee recommended and our Board approved, an equity grant to Dr. Pfeiffenberger of (i) an option to purchase 521,500 shares of common stock and (ii) 521,500 restricted stock units, or RSUs. In March 2025, our Compensation Committee approved equity grants to Dr. Russotti, Dr. Farid and Dr. Cowan consisting of (i) an option to purchase 120,000, 120,000 and 19,500 shares of common stock, respectively and 120,000, 120,000 and 19,500 RSUs, respectively. Dr. Pfeiffenberger also received a grant of 1,587,614 RSUs as a retention award in August 2025.
Stock options awarded to our NEOs generally vest 25% on the first anniversary of the grant date, with the remaining 75% vesting in equal monthly installments on the last day of each of the 36 calendar months immediately following the first anniversary of the grant date, subject generally to the NEO’s continuous service through the relevant vesting dates.
Other than the retention RSUs awarded to Dr. Pfeiffenberger in August 2025, RSUs awarded to our NEOs generally vest 25% on the first anniversary of the date of grant for each employee, with the remaining with the remaining 75% vesting on a quarterly basis for the three years thereafter, subject to the NEO’s continued employment with the Company.
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 2025, the Internal Revenue Service, or IRS, limit on eligible compensation for this purpose was $350,000. 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.
INSIDER TRADING POLICY
PLEDGING AND HEDGING POLICIES
Under the terms of our Insider Trading Policy, our executive officers and directors are prohibited from: trading in call or put options involving our securities and other derivative securities; engaging in short sales of our securities; holding our securities in a margin account; all forms of hedging or monetizing our transactions, such as zero-cost collars and forward sale contracts; and pledging company securities to secure margin or other loans.
COMPENSATION RECOVERY POLICY
Our Board has adopted a compensation recoupment or “clawback” policy, applicable to all officers subject to Section 16 of the Exchange Act. Under this policy, we will pursue recoupment of any excess compensation, which was awarded to a covered officer based on financial statements of the Company where such statements are required to be restated. In addition to recoupment of any excess compensation, we will seek to recoup up to 100% of all incentive-based compensation in the case of (i) willful, knowing or intentional misconduct or a willful, knowing or intentional violation of any of the rules or applicable legal or regulatory requirements or (ii) fraud in the course of a covered employee’s employment. The recovery period for recoupment of any compensation is up to three fiscal years preceding the date on which we determine we are required to prepare and file the restated financial statements. This policy has been adopted to comply with the final guidance under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act.
POLICIES AND PRACTICES REGARDING GRANTS OF EQUITY AWARDS
Our Compensation Committee and Board generally make equity grants on regularly scheduled dates, including (i) in the first quarter of the fiscal year for executive officers and other employees and (ii) following our annual meetings of shareholders for non-employee directors. In certain circumstances, such as in connection with new hires, promotions or similar events, or where the Board or Compensation Committee determines that making grants on such date would be in the Company’s best interest, the Board or Compensation Committee may change a regularly scheduled grant date and approve the grant of equity awards at other times.

EMPLOYMENT AGREEMENTS
We have entered into employment agreements with all of our named executive officers. The material terms of the employment agreements between us and our named executive officers are described in more detail below.
Brent Pfeiffenberger, Pharm.D.
We entered into an executive employment agreement on November 7, 2023, or the Pfeiffenberger Agreement. Pursuant to the Pfeiffenberger Agreement, Dr. Pfeiffenberger is entitled to (i) an initial annual base salary of $625,000, (ii) an initial annual bonus opportunity with a target amount of 55% of his annual base salary, (iii) a one-time signing bonus of $200,000, (iv) a one-time retention bonus of $450,000 and (v) certain sign-on equity awards (as described above). In addition, the Company agreed to reimburse Dr. Pfeiffenberger up to $150,000 for reasonable expenses incurred in connection with Dr. Pfeiffenberger’s relocation to the Philadelphia, Pennsylvania area.
Upon a termination of Dr. Pfeiffenberger’s employment without “cause” (as defined in the Pfeiffenberger Agreement) by the Company or resignation for “good reason” (as defined in the Pfeiffenberger Agreement), Dr. Pfeiffenberger is entitled to receive (i) payment of all accrued and unpaid base salary and PTO, (ii) payment of any otherwise earned but unpaid annual bonus for the prior year, (iii) payment of pro-rata bonus for the year of termination, and (iv) continuation of his base salary and COBRA premiums paid by us for 12 months. In addition, if such termination without “cause” or for “good reason” occurs, in each case, within three months prior to or 12 months following a “change in control” (as defined in the Pfeiffenberger Agreement), then (a) Dr. Pfeiffenberger’s salary and COBRA continuation period will be extended from 12 months to 18 months, (b) Dr, Pfeiffenberger will also receive a lump sum payment in an amount equal to his target annual bonus for the calendar year in which the termination occurs, and (c) all of Dr. Pfeiffenberger’s outstanding equity awards subject to vesting solely based on the passage of time and Dr. Pfeiffenberger’s continued employment will become vested on the later of Dr. Pfeiffenberger’s termination date and the change in control.
Upon a termination of Dr. Pfeiffenberger’s employment for any reason other than without cause or resignation for good reason, including, but not limited to (i) termination for cause, (ii) resignation without good reason, (iii) termination as a result of Dr. Pfeiffenberger’s “disability” (as defined in the Pfeiffenberger Agreement) or death, then the Company’s obligation to Dr. Pfeiffenberger will be limited solely to the payment of accrued and unpaid base salary through the date of such termination of employment. All other compensation and benefits will cease at the time of such termination, except as otherwise provided by COBRA.
Gregory Russotti, Ph.D.
We entered into an executive employment agreement with Dr. Russotti dated May 26, 2021, or the Russotti Agreement. The Russotti Agreement provides for an initial base salary of $430,700, an initial annual bonus opportunity of 40%, and eligibility to participate generally in our employee benefit plans. The Russotti Agreement also provides for severance benefits upon a termination of Dr. Russotti’s employment by us without “cause” (as defined in the Russotti Agreement), or resignation by Dr. Russotti for “good reason” (as defined in the Russotti Agreement), subject to Dr. Russotti’s execution of a general release of claims. The severance benefits are: (i) payment of all accrued and unpaid base salary, (ii) payment of any otherwise earned but unpaid annual bonus for the prior year, and (iii) continuation of Dr. Russotti’s base salary and payment of Dr. Russotti’s COBRA premiums by us for a period of nine months. In addition, if such termination without “cause” or resignation for “good reason” occurs within three months prior or 12 months following a “change in control” (as defined in the Russotti Agreement), then (i) the period of Dr. Russotti’s salary continuation and COBRA premium subsidy will be extended from nine months to 12 months; (ii) Dr. Russotti will receive a lump sum payment in an amount equal to his target annual

|
bonus for the calendar year in which the termination occurs, and (iii) all of Dr. Russotti’s outstanding equity awards that are subject to vesting solely based on the passage of time will vest in full on the later of Dr. Russotti’s termination date and the change in control.
In April 2023, Dr. Russotti was promoted to Interim Chief Executive Officer upon the departure of our former Chief Executive Officer, Osvaldo Flores. In connection with such promotion, we entered into a side letter to his employment agreement with Dr. Russotti dated April 12, 2023, or the Russotti Side Letter. Pursuant to the terms of the Russotti Side Letter, the term of Dr. Russotti’s service as Interim Chief Executive Officer continued until the Company successfully hired a new Chief Executive Officer, provided however, that we could terminate Dr. Russotti as Interim Chief Executive Officer and restore Dr. Russotti to his position as Chief Technology Officer at any time upon (i) hiring of a new President and Chief Executive Officer, or (ii) otherwise upon ten days’ written notice. Pursuant to the Russotti Side Letter, Dr. Russotti’s target cash bonus percentage would be calculated as a sum of the following under terms of the Side Letter: (i) 40% of Dr. Russotti’s base salary in effect as of immediately prior to April 11, 2023, multiplied by a fraction the numerator of which is the number of days in such calendar year that are not part of the term he served as Interim Chief Executive Officer, and the denominator of which is 365, and (ii) 55% of the Base Salary applicable during the term served as Interim Chief Executive Officer multiplied by a fraction the numerator of which is the number of days during the term he served as Interim Chief Executive Officer and the denominator of which is 365. The Russotti Side Letter terminated in December 2023 upon the appointment of Dr. Pfeiffenberger’s as President and Chief Executive Officer.
Adrienne Farid, Ph.D.
We entered into an executive employment agreement with Dr. Farid dated May 26, 2021, or the Farid Agreement. The Farid Agreement provides for an initial base salary of $437,800, an initial annual bonus opportunity equal to 40% of her base salary, and eligibility to participate generally in our employee benefit plans. The Farid Agreement also provides for severance benefits upon a termination of Dr. Farid’s employment by us without “cause” (as defined in the Farid Agreement), or resignation by Dr. Farid for “good reason” (as defined in the Farid Agreement), subject to Dr. Farid’s execution of a general release of claims. The severance benefits are: (i) payment of all accrued and unpaid base salary, (ii) payment of any otherwise earned but unpaid annual bonus for the prior year, and (iii) continuation of Dr. Farid’s base salary and payment of Dr. Farid’s COBRA premiums by us for a period of nine months. In addition, if such termination without “cause” or resignation for “good reason” occurs within three months prior or 12 months following a “change in control” (as defined in the Farid Agreement), then (i) the period of Dr. Farid’s salary continuation and COBRA premium subsidy will be extended from nine months to 12 months; (ii) Dr. Farid will receive a lump sum payment in an amount equal to his target annual bonus for the calendar year in which the termination occurs, and (iii) all of Dr. Farid’s outstanding equity awards that are subject to vesting solely based on the passage of time will vest in full on the later of Dr. Farid’s termination date and the change in control.
On July 8, 2025, we entered into a separation agreement with Dr. Farid, or the Farid Separation Agreement. The Farid Separation Agreement, in exchange for a release of claims and other agreements, acknowledgments and representations of Dr. Farid set forth therein, provided for the following severance benefits: (i) a lump sum severance payment of $398,888, less applicable deductions and withholdings, equal to nine months of Dr. Farid’s base salary; (ii) a lump sum payment of $123,066, less applicable deductions and withholdings, equal to the prorated portion of Dr. Farid’s 2025 performance bonus as of July 31, 2025, based on 100% attainment; (iii) if Dr. Farid timely elects to continue her group health insurance pursuant to COBRA, reimbursement of Dr. Farid’s health insurance COBRA premiums for continuing her health care coverage and the coverage of her dependents who were covered as of her departure date until the earlier of (a) nine months following July 31, 2025, (b) the date that Dr. Farid becomes eligible for group medical plan benefits under any other employer’s group medical plan, or (c) the cessation of her health continuation rights under COBRA; and (iv) all vested stock options held by Dr. Farid as of July 31, 2025, shall remain exercisable until the earlier of (a) the third year anniversary of July 31, 2025, or (b) the original expiration date for each applicable stock option.

opportunity equal to 40% of his base salary, and eligibility to participate generally in our employee benefit plans. The Cowan Agreement also provides for severance benefits upon a termination of Dr. Cowan’s employment by us without “cause” (as defined in the Cowan Agreement), or resignation by Dr. Cowan for “good reason” (as defined in the Cowan Agreement), subject to Dr. Cowan’s executive of a general release of claims. The severance benefits are (i) payment of all accrued and unpaid base salary, (ii) payment of any otherwise earned but unpaid annual bonus for the prior year, and (iii) continuation of Dr. Cowan’s base salary and payment of Dr. Cowan’s COBRA premiums by us for a period of nine months, including the 2% COBRA administrative fee.

Proprietary Information and Assignment Agreements
We have entered into proprietary information and assignment agreements, or the Information Agreements, with all of our NEOs, that include customary prohibitions against competition with us and solicitation of our customers and employees, both during employment and for one year following any cessation of employment (for each of Dr. Pfeiffenberger and Dr. Cowan) or for nine months following cessation of employment (for each of Dr. Russotti and Dr. Farid). The Information Agreements are incorporated by reference into the employment agreements and payment of any severance benefits under each executive’s employment agreement is conditioned on continued compliance with his or her Information Agreement.

CERTAIN RELATIONSHIPS AND RELATED PARTY

Since January 1, 2024, we have engaged in the following transactions with our directors, executive officers, holders of more than 5% of our voting securities, and affiliates or immediate family members of our directors, executive officers, and holders of more than 5% of our voting securities. We believe that all of these transactions were on terms as favorable as could have been obtained from unrelated third parties.
Participation in our January 2026 Private Placement
In January 2026, we entered into a securities purchase agreement with certain institutional accredited investors, pursuant to which we sold in a private placement (a) (i) 92,030,595 shares of our common stock, par value $0.0001 per share, (ii) pre-funded warrants to purchase 25,360,704 shares of common stock, or the Pre-Funded Warrants, and (b) warrants to purchase 58,695,648 shares of common stock or Pre-Funded Warrants in lieu thereof, or the Common Warrants, together with the Pre-Funded Warrants, the Warrants, at a purchase price of $1.15 per share and accompanying Common Warrant to purchase 0.5 shares of common stock or Pre-Funded Warrant and a purchase price of $1.1499 per Pre-Funded Warrant and accompanying Common Warrant to purchase 0.5 shares of common stock or Pre-Funded Warrant.

Policies and Procedures for Related Party Transactions
Our Board has adopted a written Related Party Transaction Policy that governs the review and approval of related party transactions. This Related Party Transaction Policy covers any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, where the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest. Pursuant to the Related Party Transaction Policy, if we want to enter into a transaction with a related party or an affiliate of a related party, the Audit Committee will review the proposed transaction to determine, based on applicable rules of Nasdaq and the SEC, whether such transaction requires approval by the Audit Committee. If approval is required, the proposed transaction will be reviewed at the next regular meeting of the Audit Committee, and we may not enter into a related party transaction unless the Audit Committee has specifically confirmed in writing that either no further reviews are necessary or that all requisite corporate reviews have been obtained. In reviewing and approving any such transactions, our Audit Committee is tasked to consider all relevant facts and circumstances with respect to the transaction and shall evaluate all available options, including ratification, revision or termination of the transaction. The Audit Committee will not approve or ratify a transaction with a related party unless it has determined, upon consideration of all relevant information, that the transaction is in, or not inconsistent with, the best interests of the Company or its stockholders.
Other than entry into the Letter Agreement, all of the transactions described under “Certain Relationships and Related Party Transactions” in this Proxy Statement occurred prior to or concurrently with the adoption of the Related Party Transaction Policy and as such, these transactions were not subject to the approval and review procedures set forth in the policy. However, these transactions were reviewed and approved by our Board, and the Letter Agreement was reviewed and approved in accordance with our Related Party Transaction Policy.

Represents the weighted-average exercise price of outstanding stock options. This weighted-average exercise price does not reflect shares subject to outstanding RSUs.
(2)
Represents shares available for future issues under the 2021 Plan and 2021 Employee Stock Purchase Plan, or the 2021 ESPP. No new grants will be made under our 2018 Equity Incentive Plan. 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 Board determined not to increase the shares on January 1, 2026, for the 2021 ESPP.
(3)
Does not include purchase rights accruing under the 2021 ESPP as of December 31, 2025, 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, 2026. 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, 2026, and ending on June 30, 2026, is 5,000.
(4)
Includes shares available for future issues under the 2021 ESPP and 2021 Plan. As of December 31, 2025, 639,745 shares of common stock were available for issuance under the 2021 ESPP and 4,175,446 shares of common stock were available for issuance under the 2021 Plan, which does not include 4,375,954 shares that were added to the 2021 Plan share reserve on January 1, 2026, pursuant to the evergreen provision described above.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL
OWNERS AND MANAGEMENT |
|
The following table sets forth certain information regarding the beneficial ownership of common stock as of March 31, 2026, except to the extent otherwise indicated in the footnotes below, by (a) each person known by us to be the beneficial owner of more than 5% of the outstanding shares of common stock, (b) each NEO identified in the “Summary Compensation Table” above, (c) each director and nominee for director, and (d) all executive officers and directors as a group.
The percentage of common stock outstanding is based on 180,057,279 shares of our common stock outstanding as of March 31, 2026. For purposes of the table below, and in accordance with the rules of the SEC, we deem shares of common stock subject to options that are currently exercisable or exercisable within sixty days of March 31, 2026, to be outstanding and to be beneficially owned by the person holding the options or warrants for the purpose of computing the percentage ownership of that person, but we do not treat them as outstanding for the purpose of computing the percentage ownership of any other person. Except as otherwise noted, each of the persons or entities in this table has sole voting and investing power with respect to all of the shares of common stock beneficially owned by them, subject to community property laws, where applicable. Except as otherwise noted below, the street address of each beneficial owner is c/o Century Therapeutics, Inc., 25 North 38th Street, 11th Floor, Philadelphia, PA 19104.

Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires our officers and directors, and persons who own more than ten percent of our common stock, to file reports of ownership and changes in ownership on Forms 3, 4 and 5 with the SEC. As a matter of practice, we assist many of our directors and all of our executive officers by preparing initial ownership reports and reporting ownership changes, and typically file these reports on their behalf. To our knowledge, based solely on our review of the copies of such reports filed electronically with the SEC and on written information given to us by the reporting persons, we believe that all Section 16(a) filing requirements applicable to our officers, directors and greater than ten percent beneficial owners were complied with on a timely basis during the fiscal year ended December 31, 2025, except that, due to an administrative error, one Form 3 and Form 4 for Martin Murphy were filed on April 10, 2026.

PROPOSAL 2: RATIFICATION OF APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2026
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 2026 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 2026 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, AS AMENDED, OR OUR CHARTER, TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK FROM 300,000,000 TO 450,000,000
Background
The Board has approved an amendment to our Charter, or the Charter Amendment, to increase the number of authorized shares of common stock from 300,000,000 to 450,000,000. The Charter Amendment will not change the number of authorized shares of preferred stock, which currently consists of 10,000,000 shares of preferred stock. The additional shares of common stock authorized for issuance by the Charter Amendment would be a part of the existing class of common stock and, if and when issued, would have the same rights and privileges as the common stock presently issued and outstanding.
Provided the stockholders approve the Charter Amendment, the increased number of shares would be authorized for issuance, but would remain unissued until such time as the Board approves a specific issuance of shares. Adoption of the Charter Amendment would not affect the rights of the holders of currently outstanding common stock, except for effects incidental to increasing the number of shares of our common stock outstanding, such as dilution of the earnings per share and voting rights of current holders of common stock, to the extent that any additional shares of common stock are ultimately issued out of the increase in authorized shares proposed in the Charter Amendment.
If the proposed Charter Amendment is approved by the requisite vote of the stockholders, it will become effective immediately upon the filing of a Certificate of Amendment with the Secretary of State of the State of Delaware. On April 13, 2026, our Board determined that the proposed Charter Amendment is advisable and in the best interests of the Company and our stockholders and authorized and approved the proposed Charter Amendment and directed that it be considered at the Annual Meeting. The Board of Directors reserves its right to elect not to proceed with and abandon the Charter Amendment if it determines, in its sole discretion at any time, that this proposal is no longer in the best interests of our stockholders.
Text of Proposed Charter Amendment
The proposed Certificate of Amendment reflecting the foregoing Charter Amendment is attached as Exhibit A to this Proxy Statement. However, the text of the Charter Amendment is subject to revision to include such changes as may be required by the Secretary of State of the State of Delaware and as the Board of Directors deems necessary and advisable to effect the proposed amendment of the Certificate of Incorporation.
Purposes and Effects of the Charter Amendment
Currently, we are authorized to issue up to a total of 300,000,000 shares of common stock. On the Record Date, there were shares of our common stock outstanding, warrants to purchase shares of our common stock issued and outstanding (with a weighted average exercise price of $ ), options to purchase shares of our common stock issued and outstanding under our equity incentive plans (with a weighted average exercise price of $ ), an aggregate of shares available for issuance pursuant to the our equity incentive plans and shares of our common stock issuable upon conversion of our Preferred Stock.
The ability to issue equity is fundamental to our growth strategy. In order to implement our growth strategy, we may need to raise additional financing through the issuance of equity securities. The availability of equity incentive compensation is necessary for us to attract, retain and motivate the most high-performing executives and key employees who ultimately drive our performance. The Board is recommending the proposed increase in the authorized number of shares of common stock to provide the Company with appropriate flexibility to issue additional shares in the future on a timely basis if such need arises in connection with potential financings, business combinations or other corporate purposes. Approval of the Charter Amendment could enable the Company to take advantage of market conditions, the availability of more favorable financing, and opportunities for business combinations and other strategic transactions, without the potential delay and expense associated with convening a special stockholders’ meeting. Our success also depends in part on our continued ability to attract, retain and motivate highly qualified management and key personnel, and the approval of the Charter Amendment would

|
|
ensure that there is no lack of unissued and unreserved authorized shares of common stock to provide future equity incentive opportunities.
The proposed Charter Amendment will not, by itself, have an immediate dilutive effect on our current stockholders. However, if the Charter Amendment is approved, unless otherwise required by applicable law or stock exchange rules, the Board will be able to issue the additional shares of common stock from time to time in its discretion without further action or authorization by the stockholders. The newly authorized shares of common stock would be issuable for any proper corporate purpose, including capital raising transactions of equity or convertible debt securities, the establishment of collaborations or other strategic agreements, stock splits, stock dividends, issuance under current or future equity incentive plans, future acquisitions, investment opportunities, or for other corporate purposes. The future issuance of additional shares of common stock or securities convertible into our common stock, may occur at times or under circumstances that could result in a dilutive effect on the earnings per share, book value per share, voting power and percentage interest of the present holders of our common stock, some of whom have preemptive rights to subscribe for additional shares that we may issue.
If the stockholders do not approve this Proposal 3, then we will not have the needed additional shares available.
Potential Anti-Takeover Effect
Release No. 34-15230 of the staff of the SEC requires disclosure and discussion of the effects of any action, including the proposal discussed herein, that may be used as an anti-takeover mechanism. An increase in the number of authorized shares of common stock may also, under certain circumstances, be construed as having an anti-takeover effect. Although not designed or intended for such purposes, the effect of the proposed increase might be to render more difficult or to discourage a merger, tender offer, proxy contest or change in control of us and the removal of management, which stockholders might otherwise deem favorable. For example, the authority of the Board to issue common stock might be used to create voting impediments or to frustrate an attempt by another person or entity to effect a takeover or otherwise gain control of us because the issuance of additional common stock would dilute the voting power of the common stock then outstanding. Our common stock could also be issued to purchasers who would support the Board in opposing a takeover bid which our Board determines not to be in our best interests and those of our stockholders. Although the Charter Amendment has been prompted by business and financial considerations and not by the threat of any known or threatened hostile takeover attempt, stockholders should be aware that the effect of the Charter Amendment could facilitate future attempts by us to oppose changes in control and perpetuate our management, including transactions in which the stockholders might otherwise receive a premium for their shares over then current market prices. We cannot provide assurances that any such transactions will be consummated on favorable terms or at all, that they will enhance stockholder value, or that they will not adversely affect our business or the trading price of the common stock.
The Charter Amendment is not being proposed in response to any effort of which we are aware to accumulate shares of common stock or obtain control of the Company. While it is possible that our management could use the Charter Amendment to resist or frustrate a third-party transaction providing an above-market premium that is favored by a majority of stockholders, we do not intend to construct or enable any anti-takeover defense or mechanism on its behalf. We have no current intent or plans to employ the Charter Amendment as an anti-takeover device and do not have any plans or proposals to adopt any other provisions or enter into other arrangements that may have material anti-takeover consequences.
In addition to the Charter Amendment, provisions of our governing documents and applicable provisions of Delaware law may also have anti-takeover effects, making it more difficult for, or preventing a third-party from acquiring control of the Company or changing our Board and management. These provisions may also have the effect of deterring hostile takeovers or delaying changes in the Company’s control or in our management.
Our Charter and Bylaws do not provide for cumulative voting in the election of directors. The combination of the present ownership by a relative few stockholders of a significant portion of the Company’s voting capital stock and lack of cumulative voting makes it more difficult for other stockholders to replace the members of the Board or for another party to obtain control of the Company by replacing our Board.

Certain Disadvantages of the Charter Amendment
If the authorized number of shares of common stock increases from 300,000,000 to 450,000,000 shares as proposed by this Proposal 3, we will be able to issue more shares of common stock which could result in additional dilution to current stockholders and which could have a negative effect on the market price of our common stock.
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 amendment of Article IV containing the Charter Amendment, the remainder of our Charter will remain unchanged after effectiveness of the Charter Amendment. If the proposed Charter Amendment is not approved by our stockholders, our Charter will not reflect this change. 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.

PROPOSAL 4: ADJOURNMENT OF THE ANNUAL MEETING TO THE EXTENT THERE ARE INSUFFICIENT VOTES AT THE ANNUAL MEETING TO APPROVE THE IMMEDIATELY PRECEDING PROPOSAL.
In the event that the number of shares of common stock present virtually or represented by proxy at the Annual Meeting and voting “FOR” the adoption of the Certificate of Amendment in Proposal 3 are insufficient to approve such proposal, we may move to adjourn the Annual Meeting in order to enable us to solicit additional proxies in favor of the adoption of such proposal. If the adjournment is for more than thirty days, a notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at the Annual Meeting.
For the avoidance of doubt, any proxy authorizing the adjournment of the Annual Meeting shall also authorize successive adjournments thereof, at any meeting so adjourned, to the extent necessary for us to solicit additional proxies in favor of the adoption of any such proposal.

Proposals must be sent via registered, certified, or express mail (or other means that allows the stockholder to determine when the proposal was received by the Secretary) to our Secretary at Century Therapeutics, Inc., 25 North 38th Street, 11th Floor, Philadelphia, PA 19104.

In addition, to comply with the universal proxy rules, stockholders intending to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act in the timeline provided under our Bylaws.
