QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS
AND THE ANNUAL MEETING
Q: Why have I received this Proxy Statement?

Serina is holding its Annual Meeting of Stockholders (the “Meeting”) at 11:00 a.m. Central Time on Friday, December 13, 2024 for the purposes stated in the accompanying Notice of Annual Meeting, which include (1) electing the Class I directors, (2) ratifying the appointment of our independent registered public accountants, and (3) approving a proposal to amend the Serina Therapeutics, Inc. 2024 Equity Incentive Plan (the “2024 Incentive Plan”), in substantially the form attached to this Proxy Statement as Annex A, to (i) increase the number of shares of common stock available for issuance thereunder (the “Share Reserve”) to 2,675,000, (ii) increase the number of shares that may be issued as Incentive Stock Options under the 2024 Incentive Plan to 2,675,000, (iii) provide that the Share Reserve will increase automatically on the first day of each fiscal year of the Company beginning with the 2026 fiscal year and ending on (and including) the first day of the 2034 fiscal year (each, an “Evergreen Date”), in each case, in an amount equal to 5% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year (each, an “Evergreen Increase”); provided, however, that the Board may act to provide that there will be no Evergreen Increase for a fiscal year, or that the Evergreen Increase for such fiscal year will be a lesser number of shares of common stock; and (iv) modify the Reversion of Shares Provisions (as defined hereinafter) (the “2024 Incentive Plan Amendment,” and such proposal, the “2024 Incentive Plan Amendment Proposal”). At the Meeting, our management will also report on current operations, and there will be an opportunity for discussion concerning Serina and its activities. This Proxy Statement contains information about those matters, relevant information about the Meeting, and other information that we are required to include in a proxy statement under the Securities and Exchange Commission’s (“SEC”) regulations.
Q: Who is soliciting my proxy?
The accompanying proxy is solicited by the Board of Directors of Serina for use at the Meeting. Certain of our officers, directors, and employees, none of whom will receive additional compensation therefor, may solicit proxies by telephone or other personal communication. Serina may also engage a third party proxy solicitor.
Q: Who is entitled to vote at the Meeting?
Only stockholders of record at the close of business on October 22, 2024, which has been designated as the “record date,” are entitled to notice of and to vote at the Meeting. On that date, there were 8,891,976 shares of Serina common stock, par value $0.0001 per share, issued and outstanding, which constitute the only class Serina securities outstanding entitled to vote on the matters to be presented at the meeting.
Q: What percentage of the vote is required to elect directors or to approve the other matters that are being presented for a vote by stockholders?
Directors will be elected by a plurality of the votes cast at the Meeting. All other matters to be presented for a vote at the Meeting will require the affirmative vote of a majority of the shares of common stock present and voting on the
4


matter at the Meeting, provided that the affirmative vote cast constitutes a majority of a quorum. A quorum consists of a majority of the outstanding shares of common stock entitled to vote. Notwithstanding the foregoing, if a quorum is not present the Meeting may be adjourned by a vote of a majority of the shares present. Shares of common stock held by stockholders who participate in the Meeting online or that are represented by a proxy will be deemed present for purposes of determining whether a quorum is present.
Q: How many votes do my shares represent?
Each share of Serina common stock is entitled to one vote in all matters. Stockholders are not entitled to cumulate votes in the election of directors.
Q: What are my choices when voting?
In the election of directors, you may vote for all nominees or you may withhold your vote from one or more nominees. For the vote on all other matters you may vote for the proposal, vote against the proposal, or abstain from voting on the proposal. Properly executed proxies in the accompanying form that are received at or before the Meeting will be voted in accordance with the directions noted on the proxies.
Q: What if I abstain from voting on a matter?
If you check the “abstain” box in the proxy form, or if you attend the Meeting online without submitting a proxy and you abstain from voting on a matter, or if your shares are subject to a “broker non-vote” on a matter, your shares will be deemed to have not voted on that matter in determining whether the matter has received an affirmative vote sufficient for approval. Please see “What if I do not specify how I want my shares voted?” below for additional information about broker non-votes.
Q: Can I change my vote after I submit my proxy form?
You may revoke your proxy at any time before it is voted. If you are a stockholder of record and you wish to revoke your proxy you must do one of the following things:
deliver to the Secretary of Serina a written revocation; or
deliver to the Secretary of Serina a signed proxy bearing a date subsequent to the date of the proxy being revoked; or
attend the Meeting through online participation and vote by internet voting
If you are a “beneficial owner” of shares “held in street name” you should follow the directions provided by your broker or other nominee regarding how to revoke your proxy.
Q: Can I still attend and vote at the Meeting if I submit a proxy?
You may attend the Meeting online whether or not you have previously submitted a proxy. If you previously gave a proxy, your attendance at the Meeting online will not revoke your proxy unless you also vote through internet voting during your online participation at the Meeting.
Q: How can I vote at the Meeting?
If you are a stockholder of record and you attend the Meeting online, you may vote your shares at the Meeting in the manner provided for internet voting. However, if you are a “street name” holder, you may vote your shares online only if you obtain a signed proxy from your broker or nominee giving you the right to vote your shares. Please refer to additional information in the “HOW TO ATTEND THE ANNUAL MEETING” portion of this Proxy Statement.
Even if you currently plan to attend the Meeting and vote online, we recommend that you also submit your proxy first so that your vote will be counted if you later decide not to attend and vote online at the Meeting.
Q: What are the Board of Directors’ recommendations?
The Board of Directors recommends that our stockholders vote FOR (1) each nominee for election as a Class I director, (2) approval of the appointment of Frazier & Deeter, LLC (“Frazier & Deeter”) as our independent registered
5


public accountants for the fiscal year ending December 31, 2024; and (3) approval of the 2024 Incentive Plan Amendment Proposal.
Q: What if I do not specify how I want my shares voted?
Stockholders of Record. If you are a stockholder of record and you sign and return a proxy form that does not specify how you want your shares voted on a matter, your shares will be voted FOR (1) each nominee for election as a Class I director, (2) approval of the appointment of Frazier & Deeter as our independent registered public accountants for the fiscal year ending December 31, 2024; and (3) approval of the 2024 Incentive Plan Amendment Proposal.
Beneficial Owners. If you are a beneficial owner and you do not provide your broker or other nominee with voting instructions, the broker or other nominee will determine if it has the discretionary authority to vote on the particular matter. Under the rules of the various national and regional securities exchanges, brokers and other nominees holding your shares may vote on certain routine matters, including the approval of the appointment of our independent registered public accountants, but cannot vote in the election of directors or certain other matters under applicable stock exchange rules. Based on broker non-votes with respect proposals similar to the 2024 Incentive Plan Amendment Proposal at prior annual meetings of our stockholders, we expect that brokers will consider the 2024 Incentive Plan Amendment Proposal to be a matter as to which they cannot vote unless they receive voting directions from the beneficial owners of the Serina shares they hold. If you hold your shares in street name and you do not instruct your broker or other nominee how to vote on those matters as to which brokers and nominees are not permitted to vote without your instructions, no votes will be cast on your behalf on those matters. This is generally referred to as a “broker non-vote.”
Q: What is the difference between holding shares as a stockholder of record and as a beneficial owner?
Stockholder of Record. You are a stockholder of record if at the close of business on the record date your shares were registered directly in your name with Equiniti Trust Company, LLC, our transfer agent.
Beneficial Owner. You are a beneficial owner if at the close of business on the record date your shares were held in the name of a brokerage firm or other nominee and not in your name. Being a beneficial owner means that, like most of our stockholders, your shares are held in “street name.” As the beneficial owner, you have the right to direct your broker or nominee how to vote your shares by following the voting instructions your broker or other nominee provides. If you do not provide your broker or nominee with instructions on how to vote your shares, your broker or nominee will be able to vote your shares with respect to some of the proposals, but not all. Please see “What if I do not specify how I want my shares voted?” above for additional information.
Q: What if any matters not mentioned in the Notice of Annual Meeting or this Proxy Statement come up for vote at the Meeting?
The Board of Directors does not intend to present any business for a vote at the Meeting other than the matters set forth in the accompanying Notice of Annual Meeting of Stockholders. As of the date of this Proxy Statement, no stockholder has notified us of any other business that may properly come before the Meeting. If other matters requiring the vote of the stockholders properly come before the Meeting, then it is the intention of the persons named in the accompanying form of proxy to vote the proxy held by them in accordance with their judgment on such matters.
The enclosed proxy confers discretionary authority to vote with respect to any and all of the following matters that may come before the Meeting: (1) matters that the Board of Directors did not know, a reasonable time before the mailing of the notice of the Meeting, would be presented at the Meeting; and (2) matters incidental to the conduct of the Meeting.
Q: Who will bear the cost of soliciting proxies for use at the Meeting?
Serina will bear all of the costs of the solicitation of proxies for use at the Meeting. In addition to the use of the mails, proxies may be solicited by a personal interview, telephone, or electronic communication by our directors, officers, and employees, who will undertake such activities without additional compensation. Banks, brokerage houses, and other institutions, nominees, or fiduciaries will be requested to forward the proxy materials to the beneficial owners of the common stock held of record by such persons and entities and will be reimbursed for their reasonable expense incurred in connection with forwarding such material.

The purpose of the Code of Ethics is to promote (i) honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; (ii) full, fair, accurate, timely, and understandable disclosure in reports and documents that we file with or submit to the SEC and in our other public communications; (iii) compliance with applicable governmental rules and regulations; (iv) prompt internal reporting of violations of the Code of Ethics to an appropriate person or persons identified in the Code of Ethics; and (v) accountability for adherence to the Code of Ethics. A copy of our Code of Ethics has been posted on our internet website and can be found at www.serinatherapeutics.com. We intend to disclose any future amendments to certain provisions of our Code of Ethics, and any waivers of those provisions granted to our principal executive officers, principal financial officer, principal accounting officer or controller or persons performing similar functions, by posting the information on our website within four business days following the date of the amendment or waiver.

Board Leadership Structure

We have separated the positions of Chair of the Board and Chief Executive Officer in order to reinforce the independence of the board of directors from management, create an environment that encourages objective oversight of management’s performance and enhances the effectiveness of our Board as a whole. As such, our Board is chaired by Dr. Gill, and Mr. Ledger serves as our Chief Executive Officer.
The Board’s Role in Risk Management
One of the key functions of our Board is to oversee our risk management process. We do not have a standing risk management committee, but rather administer this oversight function directly through the Board as a whole, as well as through various standing committees that address risks inherent in their respective areas of oversight. In particular, the Board is responsible for monitoring and assessing strategic risk exposure and the Audit Committee has the responsibility to consider and discuss the major financial risk exposures and the steps our management should take to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management will be undertaken. The Audit Committee is also expected to monitor compliance with legal and regulatory requirements. The Compensation Committee also assesses and monitors whether our compensation plans, policies and programs comply with applicable legal and regulatory requirements.
Hedging Transactions
We have adopted a policy that prohibits our directors and our officers and other employees from purchasing financial instruments, including prepaid variable forward contracts, equity swaps, collars, and exchange funds, or to otherwise engage in transactions that hedge or offset, or that are designed to hedge or offset, risks of any decrease in the market value of our common stock or other equity securities granted to the employee or director as part of their compensation, or held, directly or indirectly, by the employee or director.
Committees of the Board

The Board of Directors has an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, and a Science and Technology Committee, each of which has the composition and the responsibilities described below.
Audit Committee
During 2023, the Audit Committee was comprised of: (i) Michael H. May (Chair), who served until the day of the 2023 annual meeting of the stockholders, when his service on Audit Committee expired, (ii) Joanne M. Hackett, who served until August 9, 2023, when she was appointed Interim Chief Executive Officer of AgeX, and (iii) and Jean-Christophe Renondin, who served for the duration of 2023. The current members of the Audit Committee are Steven Mintz (Chair) and Remy Gross. The Audit Committee held eight meetings during 2023. The Audit Committee approved certain matters by unanimous written consent on two occasions in lieu of a meeting during 2023.

The purpose of the Audit Committee is to oversee the corporate accounting and financial reporting processes and audits of financial statements. For this purpose, the Audit Committee performs several functions, including among other things:
evaluate the independent registered public accounting firm’s qualifications, independence and performance;
determine whether to retain or terminate the engagement of the existing independent registered public accounting firm or to appoint and engage a different independent registered public accounting firm;
review all relationships between any prospective independent registered accounting firm and us that may reasonably be thought to bear on independence prior to engagement of any prospective independent registered accounting firm;
review and approve the scope of the annual audit and pre-approves the audit and non-audit fees and services;
obtain and review a report by the independent outside auditor describing that firm’s internal quality-control procedures on an annual basis;
13


annually review all relationships between the independent outside auditor and us that may reasonably be thought to bear on independence;
review and monitor compliance with programs and policies designed to ensure compliance with laws and regulations and the Code of Business Conduct and Ethics, including review and approval of all related party transactions on an ongoing basis;
establish procedures for the receipt, retention and treatment of complaints received regarding accounting, internal accounting controls or auditing matters;
discuss with management and the independent registered public accounting firm the results of the annual audit and the review of our quarterly financial statements;
approve the retention of the independent outside auditor to perform any proposed permissible non-audit services;
monitor the rotation of partners of the independent outside auditors on our engagement team in accordance with requirements established by the SEC;
discuss on a periodic basis, or as appropriate, with management the policies and procedures with respect to risk assessment and risk management;
review our financial statements and our management’s discussion and analysis of financial condition and results of operations to be included in our annual and quarterly reports to be filed with the SEC;
consider and adopt policies regarding Audit Committee preapproval of employment of individuals employed or formerly employed by our independent outside auditor;
investigate any reports received through the ethics helpline and report to our Board periodically with respect to the information received through the ethics helpline and any related investigations;
review our critical accounting policies and estimates; and
review the Audit Committee charter and the committee’s performance at least annually.

All members of the Audit Committee during 2023 met the requirements for financial literacy under the applicable rules and regulations of the SEC and the NYSE American. Under the rules of the SEC, members of the Audit Committee must also meet heightened independence standards. We believe that each member of the Audit Committee during 2023 was independent under the applicable rules of the SEC and the NYSE American.

All current members of the Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and the NYSE American and Mr. Mintz qualifies as an audit committee financial expert as defined under the applicable rules of the SEC and has the requisite financial sophistication as defined under the applicable rules and regulations of the NYSE American. Under the rules of the SEC, members of the Audit Committee must also meet heightened independence standards. We believe that each member of the Audit Committee is independent under the applicable rules of the SEC and the NYSE American. The Audit Committee operates under a written charter that satisfies the applicable standards of the SEC and the NYSE American. A copy of the Audit Committee Charter has been posted on our internet website and can be found at www.serinatherapeutics.com.
Compensation Committee
During 2023, the Compensation Committee was comprised of: (i) Gregory H. Bailey, M.D. (Chair), who served for the duration of 2023, (ii) Michael H. May, who served until the day of the 2023 annual meeting of the stockholders, when his service on Compensation Committee expired, (iii) Joanne M. Hackett, who served until August 9, 2023, when she was appointed Interim Chief Executive Officer of AgeX, and (iv) and Jean-Christophe Renondin, who served for the duration of 2023. The current members of the Compensation Committee are J. Milton Harris, Ph.D. (Chair), Gregory H. Bailey, M.D., and Steven Mintz.

The Compensation Committee oversees policies relating to compensation and benefits of officers and employees. The Compensation Committee reviews and approves corporate goals and objectives relevant to compensation of the executive officers, evaluates the performance of these officers in light of those goals and objectives and approves the compensation of these officers based on such evaluations. The Compensation Committee also reviews and approves or makes recommendations to the Board regarding the issuance of stock options and other awards under our stock plans to the executive officers. The Compensation Committee will review and evaluate, at least annually, the performance of the Compensation Committee and its members, including compliance by the Compensation Committee with our charter. A copy of the Compensation Committee Charter has been posted on our internet website and can be found at www.serinatherapeutics.com.

14


The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all of our books, records, facilities and personnel. In addition, under its charter, the Compensation Committee has the authority to obtain, at our expense, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources the Compensation Committee considers necessary or appropriate in the performance of our duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under its charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and the NYSE American, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

To qualify as independent to serve on the Compensation Committee, the NYSE American Listing Rules require a director not to accept any consulting, advisory, or other compensatory fee from us, other than for service on our Board, and that our Board consider whether a director is affiliated with us and, if so, whether such affiliation would impair the director’s judgment as a member of the Compensation Committee. We believe that the composition of the Compensation Committee during 2023 met the requirements for independence under, and the functioning of such Compensation Committee complied with any applicable requirements of, the rules and regulations of the SEC and the NYSE American. We believe that the composition of the Compensation Committee meets the requirements for independence under, and the functioning of such Compensation Committee complies with any applicable requirements of, the rules and regulations of the SEC and the NYSE American.

Compensation Committee Interlocks and Inside Participation

Each member of the Compensation Committee is a “non-employee” director within the meaning of Rule 16b-3 of the rules promulgated under the Exchange Act and independent within the meaning of the independent director guidelines of the NYSE American. None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers who serves on the Board or Compensation Committee.

Nominating and Corporate Governance Committee

During 2023, the Nominating and Corporate Governance Committee was comprised of: (i) Jean-Christophe Renondin (Chair), who served for the duration of 2023, (ii) Michael H. May, who served until the day of the 2023 annual meeting of the stockholders, when his service on Nominating and Corporate Governance Committee expired, (iii) Joanne M. Hackett, who served until August 9, 2023, when she was appointed Interim Chief Executive Officer of AgeX, and (iv) and Gregory H. Bailey, M.D., who served for the duration of 2023. The members of the Nominating and Corporate Governance Committee are J. Milton Harris, Ph.D. (Chair), Remy Gross and Richard Marshall, M.D., Ph.D.

The Nominating and Corporate Governance Committee is responsible for making recommendations to our Board regarding candidates for directorships and the size and composition of our Board. In addition, the Nominating and Corporate Governance Committee is responsible for overseeing corporate governance policies and reporting and making recommendations to the Board concerning governance matters. A copy of the Nominating and Corporate Governance Committee Charter has been posted on our internet website and can be found at www.serinatherapeutics.com.

Science and Technology Committee

The members of the Science and Technology Committee are J. Milton Harris, Ph.D. (Chair), and Remy Gross. The Science and Technology Committee was formed by the Board on May 30, 2024.

The purpose of the Science and Technology Committee is to assist the Board and management in understanding any emerging or evolving scientific or technological issues of importance to the Company; assist the Board in understanding the status and progress of certain of the Company’s research and development programs, manufacturing and regulatory strategies and business development opportunities; advise management of the Company on certain aspects of the
15


Company’s technology development, as required to achieve its long-term strategic technology development objectives, including the research and development programs, manufacturing and regulatory strategies, business development opportunities, and patent, trademark, and licensing matters; assist the Board in understanding the licensing of the Company’s technology and the licensing of third party technology; and assist the Board in understanding the Company’s intellectual property position in connection with the foregoing and otherwise.

For this purpose, the Science and Technology Committee performs several functions, including among other things:

For any internal or external programs and investments in products and technologies (e.g., potential licenses, acquisitions, collaborations or equity investments) that require approval by the full Board, the Committee may be asked to provide the Board and management with its advice prior to such Board action;
regularly review and make recommendations to the Board and management with respect to the Company’s research and development pipeline;
conduct or authorize investigations into any matters within the scope of its responsibilities as it shall deem appropriate, including the authority to request any officer, employee or advisor of the Company to meet with the Committee or any advisors engaged by the Committee;

review and reassess the adequacy of this Charter and recommend any proposed changes to the Board for approval; and
periodically evaluate its own performance.
Report of the Audit Committee on the Audit of Our Financial Statements
The following is the report of the Audit Committee with respect to AgeX's audited financial statements for the year ended December 31, 2023. The current members of our Audit Committee, did not join the Audit Committee until after our Annual Report on Form 10-K for the year ended December 31, 2023, was filed and did not participate in discussions with our independent registered public accountants concerning the audit of our financial statements for the year ended December 31, 2023 or other matters discussed in the Audit Committee report.
The information contained in this report shall not be deemed “soliciting material” or otherwise considered “filed” with the SEC, and such information shall not be incorporated by reference into any future filing under the
16


Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except to the extent that Serina specifically incorporates such information by reference in such filing.
The members of the Audit Committee held discussions with our management and representatives of WithumSmith + Brown PC, our independent registered public accountants during our fiscal year ended December 31, 2023, concerning the audit of our financial statements for the year ended December 31, 2023. The independent public accountants are responsible for performing an independent audit of our financial statements and issuing an opinion on the conformity of those audited financial statements with generally accepted accounting principles in the United States. The Audit Committee does not itself prepare financial statements or perform audits, and its members are not auditors or certifiers of our financial statements.
The Audit Committee members reviewed and discussed with management and representatives of the auditors the audited financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2023. Our auditors also discussed with the Audit Committee the adequacy of our internal control over financial reporting.
The Audit Committee members discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Audit Committee received the written disclosures and the letter mandated by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and discussed with the independent accountant the independent accountant’s independence. Based on the reviews and discussions referred to above, the Audit Committee unanimously recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC.
The Audit Committee also met on a quarterly basis with the auditors during 2023 to review and discuss our financial statements for the quarter and the adequacy of internal control over financial reporting.

The Audit Committee: Steven Mintz (Chair) and Remy Gross.

Nomination of Candidates for Election as Directors
Nominating Policies and Procedures
The Nominating and Corporate Governance Committee will consider nominees for election as directors proposed by stockholders, provided that they notify the Nominating and Corporate Governance Committee of the nomination in writing at least 120 days prior to the one-year anniversary of the preceding year’s annual meeting; provided, however, that if the date of the Meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered, or mailed and received, not later than the 90 days day prior to such annual meeting or, if later, the tenth day following the day on which public disclosure of the date of such annual meeting was first made. Within the applicable time frame the stockholder and the nominee must also provide the Nominating and Corporate Governance Committee with all information that the Nominating and Corporate Governance Committee may reasonably request regarding the nominee.
The Board and the Nominating and Corporate Governance Committee have not set any specific minimum qualifications that a prospective nominee would need in order to be nominated to serve on the Board of Directors. Rather, in evaluating any new nominee or incumbent director, the Nominating and Corporate Governance Committee will consider whether the particular person has the knowledge, skills, experience, and expertise needed to manage our affairs in light of the skills, experience, and expertise of the other members of the Board as a whole. The Nominating and Corporate Governance Committee will also consider whether a nominee or incumbent director has any conflicts of interest with Serina that might conflict with our Code of Ethics or that might otherwise interfere with their ability to perform their duties in a manner that is in the best interest of Serina and its stockholders. The Nominating and Corporate Governance Committee will also consider whether including a prospective director on the Board will result in a Board composition that complies with (a) applicable state corporate laws, (b) applicable federal and state securities laws, and (c) the rules of the SEC and each stock exchange on which our shares are listed.
The Board of Directors and the Nominating and Corporate Governance Committee have not adopted specific policies with respect to a particular mix or diversity of skills, experience, expertise, perspectives, and background that nominees should have. However, the present Board was assembled with a focus on attaining a Board comprised of people with substantial experience in bioscience, the pharmaceutical industry, corporate management, and finance. The Board
17


believes that this interdisciplinary approach will best suit our needs as we work to develop and commercialize novel therapeutics targeting human aging and degenerative diseases.
EXECUTIVE COMPENSATION
We are an “emerging growth company” as defined in the JOBS Act, as amended, and a “smaller reporting company” as defined in the rules and regulations of the SEC. As an emerging growth company and as a smaller reporting company we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable, in general, to public companies that are not emerging growth companies or smaller reporting companies. Accordingly, this Proxy Statement includes reduced disclosure about our executive compensation arrangements.

Narrative Disclosure to Legacy Serina Summary Compensation Table

2023 Salaries and Bonuses

Each of Mr. Ledger, Dr. Moreadith and Dr. Viegas received a base salary (or base contractor fee, in the case of Mr. Ledger) in 2023 to provide a fixed component of compensation reflecting the executive’s skill set, experience, role, and responsibilities. Annual base salaries and fees of executives are established at the date of hire and then reviewed periodically by the Serina Board.

For 2023, Legacy Serina’s executive bonus program was not based on pre-determined performance metrics. Legacy Serina’s executive officers were eligible to receive cash incentive compensation awarded at the discretion of the Legacy Serina Board of up to 25% of such executive officer’s base salary or fee, as applicable.

2023 Equity Compensation

18


Legacy Serina did not grant stock awards or stock options to any of its named executive officers in 2022. Legacy Serina granted stock options in the past, and its stock options generally allowed employees to purchase shares of Legacy Serina common stock at a price per share equal to the fair market value of Legacy Serina common stock on the date of grant, as determined by the Legacy Serina Board.

Other Elements of Compensation

During their employment, our named executive officers are eligible to participate in employee benefit plans and programs to the same extent and on the same terms as our other full-time employees generally. We do not maintain any defined benefit pension plans or any nonqualified deferred compensation plans. We offer eligible full-time employees, including the eligible NEOs, the opportunity to participate in a tax-qualified 401(k) plan. Employees can contribute eligible earnings up to the IRS’s annual limits on a before-tax basis, which was generally $22,500 for 2023. As described below, Mr. Ledger served as a contractor of Legacy Serina and not as an employee, and thus was not entitled to participate in any employee benefit plans.

Executive Compensation Arrangements

Below are descriptions of our employment arrangements with our named executive officers, each of whom is employed “at will.”

Mr. Ledger

Mr. Ledger served as Legacy Serina’s Chief Financial Officer from June 2021 until March 2024, when he was appointed as the Interim Chief Executive Officer of the Company. On September 8, 2024, Mr. Ledger was appointed as the Company’s Chief Executive Officer (the “CEO Appointment”). Prior to the CEO Appointment, Mr. Ledger was an independent contractor and not our employee. Mr. Ledger and Legacy Serina entered into a letter agreement, effective as of July 29, 2021, pursuant to which Mr. Ledger was granted options to purchase 116,666 shares of Legacy Serina common stock as compensation for providing certain financial advisory services to us. The cash compensation paid by Legacy Serina to Mr. Ledger in consideration for services provided by Mr. Ledger as an independent contractor was not subject to any written agreement between Mr. Ledger and Legacy Serina. Mr. Ledger’s base independent contractor compensation was reviewed periodically by our Board and Mr. Ledger and our Board could, but was not required to, agree to increase his base independent contractor compensation. For the year ended December 31, 2023, Mr. Ledger’s annual base independent contractor compensation was $170,000.

In connection with the CEO Appointment, the Company, Legacy Serina, and Mr. Ledger entered into an employment agreement (the “Ledger Employment Agreement”) that provides for an annual base salary of $450,000 and an annual incentive compensation opportunity of up to 50% of base salary, subject to the discretion of the Board. Mr. Ledger’s base salary will automatically increase to $500,000 annually, and he will receive a one-time cash bonus upon the attainment of certain strategic goals. In addition, Mr. Ledger received a grant of 501,851 options to purchase common stock of the Company, which was granted pursuant to, and is governed by and subject in all respects to, the terms and conditions of the 2024 Incentive Plan and the Non-Qualified Stock Option Agreement entered into by and between the Company and Mr. Ledger. 75% of the options will vest over time upon Mr. Ledger’s continued employment with the Company, with an initial vesting of 47,049 shares on March 9, 2025, and the remainder vesting ratably monthly thereafter over a four-year vesting period. The remaining 25% of the options will only vest upon the achievement of certain strategic goals as well as Mr. Ledger’s continued employment with the Company, upon the same vesting schedule as the other options.
The Ledger Employment Agreement restricts Mr. Ledger’s ability to compete with the Company for two years after employment, and to solicit employees of the Company for 18 months after employment. If Mr. Ledger is terminated by the Company without cause, Mr. Ledger will receive 12 months of base salary and a pro-rated bonus equal to at least one-half of his full annual bonus opportunity. The Ledger Employment Agreement will continue indefinitely until terminated by either party.

Dr. Moreadith

Dr. Moreadith’s employment with us is not subject to any written agreement between us and Dr. Moreadith. Dr. Moreadith’s base salary is reviewed periodically by our Board and our Board may, but is not required to, increase his base salary at its discretion. For the year ended December 31, 2023, Dr. Moreadith’s annual base salary was $336,723.
19



Dr. Viegas

Dr. Viegas’ employment with us terminated on July 15, 2024, when Dr. Viegas retired. His employment was not subject to any written agreement. In connection with his retirement, the Company and Dr. Viegas entered into a consulting agreement, effective July 14, 2024, pursuant to which Dr. Viegas agreed to serve as a consultant for the Company on various projects.

Post-Employment Compensation and Change in Control Payments and Benefits

The Ledger Employment Agreement provides that, if Mr. Ledger’s employment is terminated for no cause by the Company, Mr. Ledger will receive 12 months of base salary with a pro-rated bonus (minimum of one-half of the full annual bonus). If Mr. Ledger’s employment is terminated for cause by the Company or by Mr. Ledger voluntarily, Mr. Ledger will not be entitled to any severance payment. The Ledger Employment Agreement defines “cause” as (a) Mr. Ledger’s failure to perform Mr. Ledger’s duties, (b) Mr. Ledger’s failure to comply with any valid and legal directive of the Company, (c) Mr. Ledger’s engagement in dishonesty, illegal conduct, or misconduct which is, in each case, injurious to the Company or its affiliates, (d) Mr. Ledger’s embezzlement, misappropriation, or fraud, whether or not related to Mr. Ledger’s employment with the Company, (e) Mr. Ledger’s conviction of or plea of guilty or nolo contendere to a crime that constitutes a felony (or state law equivalent) or a crime that constitutes a misdemeanor involving moral turpitude, (f) Mr. Ledger’s violation of the Company's written policies or codes of conduct, including written policies related to discrimination, harassment, performance of illegal or unethical activities, and ethical misconduct, (g) Mr. Ledger’s willful unauthorized disclosure of Confidential Information or violation of his restrictive covenants (as defined in Section 7 of the Ledger Employment Agreement), (h) Mr. Ledger’s material breach of any material obligation under the Ledger Employment Agreement or any other written agreement between Mr. Ledger and the Company, or (i) Mr. Ledger’s engagement in conduct that brings or is reasonably likely to bring the Company negative publicity or into public disgrace, embarrassment, or disrepute.

Neither Dr. Moreadith nor Dr. Viegas is party to any agreement, plan, or policy providing post-employment severance or change in control payments or benefits.

Instead, these amounts reflect the aggregate grant date fair value of each stock option granted, computed in accordance with the provisions of FASB ASC Topic 718, Compensation-Stock Compensation. AgeX used the Black-Scholes Pricing Model to compute option fair values based on applicable exercise and stock prices, an expected option term, volatility assumptions, and risk-free interest rates. AgeX’s Named Executive Officers will only realize compensation upon exercise of the stock options and to the extent the trading price of AgeX’s common stock is greater than the exercise price of such stock options at the time of exercise. For Dr. West, the amount in this column also reflects the incremental fair value incurred in connection with the extension of the exercise period of 1,330,000 of Dr. West’s stock options from 90 days to four years following his termination. For Dr. Malik, the amount in this column also reflects the incremental fair value incurred in connection with the acceleration of vesting and extension of the expiration date of options to purchase 485,625 shares of AgeX common stock.

Except as otherwise disclosed below, one fourth of the options will vest upon completion of 12 full months of continuous employment measured from the date of grant, and the balance of the options vest in 36 equal monthly installments commencing on the first anniversary of the date of grant, based on the completion of each month of continuous service as an employee or director of AgeX or our subsidiaries.

Amounts represent 401(k) matching contributions by AgeX for the periods presented unless described otherwise in the footnotes below.

In order to receive the severance benefits, Ms. Park was required to execute a general release of all claims against us.

Dr. Malik

The termination of Dr. Malik’s service in December 2023 was treated as a termination without “cause”, and all outstanding equity grants that he then held automatically vested as to the number unvested shares that would otherwise have vested during the twelve months following termination; and with respect to outstanding vested but unexercised stock option grants, the post-termination exercise period was extended to the earlier of the date twelve months after termination or the expiration date of the stock option.

Risk Considerations and Recoupment Policies
The Compensation Committee of our Board of Directors considers, in establishing and reviewing the executive compensation program, whether the program encourages unnecessary or excessive risk taking. Most of our executive compensation arrangements include a fixed salary that provides a steady income so that executives do not feel pressured to focus exclusively on stock price performance or short-term financial targets to the detriment of our long-term operational and strategic objectives. We supplement fixed salaries with discretionary bonus awards based on the executive’s performance as well as the performance of Serina. The stock options and RSUs that we have granted to our executive officers under the AgeX 2017 Incentive Plan, the Legacy Serina 2017 Option Plan, and the 2024 Incentive Plan vest over four years, assuring that the executives take a long-term perspective in viewing their equity ownership. Although we have not adopted compensation plans, or made incentive awards, based on quantified financial performance measures, we have adopted a Clawback Policy intended to comply with Section 811 of the NYSE American Company Guide. In the event of certain restatements of Serina financial statements, the Clawback Policy will require Serina to recoup from its executive
23


officers compensation that is granted, earned or vested based wholly or in part upon the attainment of a financial reporting measure, to the extent such compensation (a) was granted during the three fiscal years preceding a determination that Serina financial statements must be restated, and (b) exceeds the amount of compensation that would have been granted had the grant been based on the restated financial statement amounts. A copy of our Clawback Policy has been posted on our company website and can be found at www.serinatherapeutics.com.

DIRECTOR COMPENSATION

Director Compensation Program

Following the Merger, on March 27, 2024, our Board adopted a new outside director compensation policy, which became effective on April 1, 2024 (the “Director Compensation Policy”). On May 30, 2024, in connection with the creation of the Science and Technology Committee, the Board revised the Director Compensation Policy to provide for the compensation of members of the Science and Technology Committee. As revised, the Director Compensation Policy provides that each non-employee director will receive an annual retainer of $40,000, an annual retainer of $60,000 for serving as chair of our Board, a $10,000 annual retainer for serving as the chair of the Audit Committee, a $5,000 annual retainer for serving as a member of the Audit Committee, a $5,000 annual retainer for serving as the chair of the Compensation Committee, a $2,500 annual retainer for serving as a member of the Compensation Committee, a $5,000 annual retainer for serving as the chair of the Nominating and Corporate Governance Committee, a $2,500 annual retainer for serving on the Nominating and Corporate Governance Committee, a $2,500 annual retainer for serving as the chair of the Science and Technology Committee, and a $1,500 annual retainer for serving as a member of the Science and Technology Committee, in each case to be paid quarterly in arrears and prorated based on the number of actual days served on our Board or applicable committee. Each non-employee director who serves as a committee chair of our Board will receive the cash retainer fee as the chair of the committee but not the cash retainer fee as a member of that committee, provided that the non-employee director who serves as the non-employee chair of our Board will receive the annual retainer fees for such role as well as the annual retainer fee for service as a non-employee director. The above-listed fees for service as non-employee chair of our Board or a chair or member of any committee are payable in addition to the non-employee director retainer.

In addition, the Director Compensation Policy provides that each individual who was a non-employee director as of the effective date of the policy was granted an award of stock options to purchase 40,000 shares of our common stock (the “Transition Award”). Each Transition Award will vest in equal yearly installments over the 3-year period from the date of grant, in each case subject to the non-employee director continuing to be a non-employee director through the applicable vesting date.

The Director Compensation Policy also provides that each individual who first becomes a non-employee director following the effective date of the policy and who did not receive a Transition Award will be granted an award of stock options to purchase 40,000 shares of our common stock (the “Initial Award”). The Initial Award will be granted automatically on the first trading day on or after the date on which such individual first becomes a non-employee director (the first date as a non-employee director, the “Initial Start Date”), whether through election by our stockholders or appointment by our Board to fill a vacancy. Each Initial Award will be scheduled to vest in equal yearly installments over the 3-year period from the date of grant, in each case subject to the non-employee director continuing to be a non-employee director through the applicable vesting date.

On April 1st of each year, beginning April 1, 2025, each non-employee director automatically will be granted an award of stock options (an “Annual Award”) to purchase 10,000 shares of our common stock. Each Annual Award will be scheduled to vest in full on the first anniversary of the date on which the Annual Award is granted, in each case subject to the non-employee director continuing to be a non-employee director through the applicable vesting date.

Legacy Serina Director Compensation

During the year ended December 31, 2023, none of the non-employee directors who served on the Legacy Serina Board received compensation from Legacy Serina for their services as a director.

The table below shows the aggregate number of outstanding option awards held as of December 31, 2023 by each non-employee director who was serving as of December 31, 2023. None of our non-employee directors held any other equity awards as of December 31, 2023.

PRINCIPAL STOCKHOLDERS AND SECURITY OWNERSHIP OF MANAGEMENT
Security Ownership of Certain Beneficial Owners and Management
The following table sets forth information regarding the beneficial ownership of our common stock as of October 22, 2024, by (i) each of our Named Executive Officers, (ii) each of our directors, (iii) all of our directors and executive officers as a group; and (iv) each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of our common stock. Our calculation of the percentage of beneficial ownership is based on 8,891,976 shares of common stock outstanding as of October 22, 2024.
Beneficial ownership is determined according to the rules of the SEC and generally means that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power of that security, including options that are currently exercisable or exercisable within 60 days of October 22, 2024, and restricted stock units that will vest within 60 days of October 22, 2024. Shares of our common stock issuable pursuant to stock options and restricted stock units currently exercisable or exercisable within 60 days of October 22, 2024, and restricted stock units that will vest within 60 days of October 22, 2024, are deemed outstanding for computing the percentage of the person holding such equity awards and the percentage of any group of which the person is a member but are not deemed outstanding for computing the percentage of any other person. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons named in the table below have sole voting and investment power with respect to all shares they beneficially own, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Section 16 of the Exchange Act. . Unless otherwise indicated below, each person or entity has an address in care of our principal executive offices at 601 Genome Way, Suite 2001, Huntsville, Alabama 35806.

Related Person Transactions Policy and Procedures

Those transactions are referred to as Related Person Transactions. A Related Person Transaction will be subject to review and approval by the Audit Committee of our Board prior to effectiveness or consummation, to the extent practical. The Audit Committee will review the relevant information available to it about the Related Person Transaction. The Audit Committee may approve or ratify the Related Person Transaction only if the Audit Committee determines that, under the circumstances, the transaction is in, or is not in conflict with, our best interests.

Certain Related Person Transactions
2020 Loan Agreement and New Warrant Agreement
28


On March 30, 2020, AgeX and Juvenescence entered into the 2020 Loan Agreement (the “2020 Loan Agreement”), which was amended on March 13, 2023, to extend the maturity date by one year, pursuant to which AgeX borrowed $8.0 million from Juvenescence. During July 2023, the full $8 million of 2020 Loan Agreement indebtedness was extinguished in exchange for shares of AgeX Series A preferred stock pursuant to the 2023 Exchange Agreement between AgeX and Juvenescence described below.

Common Stock and 2020 Warrants – Under the terms of the 2020 Loan Agreement, AgeX issued to Juvenescence 28,500 shares of AgeX common stock as an arrangement fee for the loan facility when AgeX borrowed an aggregate of $3.0 million, and AgeX issued to Juvenescence warrants to purchase a total of 3,670,663 shares of AgeX common stock (the “2020 Warrants”). The number of 2020 Warrants issued was determined as follows: each time AgeX received an advance of funds under the 2020 Loan Agreement, AgeX issued to Juvenescence a number of 2020 Warrants equal to 50% of the number determined by dividing the amount of the advance by the applicable market price of AgeX common stock. The market price for each 2020 Warrant when issued was the closing price per share of AgeX common stock on the NYSE American on the date of the applicable notice from AgeX requesting a draw of funds that triggered the obligation to issue the 2020 Warrant. The exercise price of the 2020 Warrants is the applicable market price of AgeX common stock. Each of the 2020 Warrants will expire at 5:00 p.m. New York time three years after the date of our issuance. AgeX had issued to Juvenescence 2020 Warrants to purchase a total of 3,670,663 shares of AgeX common stock of which 1,182,262 were outstanding as of September 30, 2023. The exercise prices of the 2020 Warrants that were still outstanding as of September 30, 2023, range from $0.81 per share to $1.895 per share representing the market closing price on the NYSE American of AgeX common stock on the one day prior to delivery of the drawdown notices. The number of shares issuable upon exercise of the 2020 Warrants and the exercise price per share are subject to adjustment upon the occurrence of certain events such as a stock split or reverse split or combination of the common stock, stock dividend, recapitalization or reclassification of the common stock, and similar events.
Convertible Notes Agreement and Asset Contribution Agreement
On March 26, 2024, AgeX entered into an Asset Contribution Agreement with UniverXome (the “Asset Contribution Agreement”) pursuant to which AgeX transferred to UniverXome all of AgeX’s capital stock in Reverse Bio and ReCyte, along with certain patents, patent applications, and other intellectual property, certain biological materials, certain trademarks and service marks, certain equipment, certain inventory, and certain files and records relating to the foregoing, and UniverXome assumed all of the Liabilities (as defined in the Asset Contribution Agreement) in existence as the Effective Time (as defined in the Merger Agreement) other than the Transaction Expenses (as defined in the Merger Agreement) and certain other liabilities. Concurrently with the execution of the Asset Contribution Agreement, AgeX, and its subsidiaries UniverXome, Reverse Bio, and ReCyte (the “Subsidiary Obligors”), entered into an Agreement with Respect to the Convertible Notes (the “Convertible Notes Agreement”) with Juvenescence.

Pursuant to the Convertible Notes Agreement, AgeX transferred to UniverXome, and UniverXome assumed, all of AgeX’s rights and obligations under the 2022 Secured Note and 2023 Secured Note and related Security Agreements described below. Juvenescence agreed to release AgeX from its obligations under (i) the 2022 Secured Note and the 2023 Secured Note (collectively, the “Convertible Notes”), together with (ii) all agreements evidencing or securing the Convertible Notes, including the related Security Agreements, and UniverXome assumed all of AgeX’s obligations under the Convertible Notes and related agreements, including the Security Agreements. As a result, (i) Juvenescence agreed to look solely to UniverXome, and ReCyte and Reverse Bio as guarantors, for any and all obligations, including repayment, under the Convertible Notes, the Security Agreements, and related documents, and (ii) Juvenescence released its security interests in the assets of AgeX and certain subsidiaries, including its security interests in the stock of UniverXome, the stock and assets of Merger Sub, the stock and assets of NeuroAirmid, and certain cGMP embryonic cell lines used to support the NeuroAirmid business, and any security interest that it might have in the stock and assets of Merger Sub and Legacy Serina, while retaining its security interest in the stock and assets of ReCyte and Reverse Bio and in AgeX assets transferred to UniverXome.

The funds were used to settle legal expenses and demand fees against AgeX due to the Merger.

From January 1 through June 30, 2024, AgeX drew in the aggregate $6,325,000 of its credit available under the 2022 Secured Note with Juvenescence. As of June 30, 2024, AgeX had borrowed a total of $26,485,000 under the 2022 Secured Note, of which $7,500,000 was borrowed during the year ended December 31, 2023.

As an arrangement fee for the 2022 Secured Note, AgeX agreed to pay Juvenescence an origination fee in an amount equal to 4% of the amount each draw of loan funds, which will accrue as each draw is funded, and an additional 4% of all the total amount of funds drawn that will accrue following the end of the period during which funds may be drawn from the line of credit. The origination fee will become due and payable on the repayment date or in a pro rata amount with any prepayment of in whole or in part of the outstanding principal balance of the 2022 Secured Note.

2022 Warrants – Upon each drawdown of funds under the 2022 Secured Note prior to June 2, 2023 when the Third Amendment went into effect, AgeX issued to Juvenescence warrants to purchase shares of AgeX common stock (“2022 Warrants”). The 2022 Warrants are governed by the terms of a Warrant Agreement between AgeX and Juvenescence. The number of 2022 Warrants issued with respect to each draw of loan funds was equal to 50% of the number determined by dividing the amount of the applicable loan draw by the applicable Market Price. The Market Price was the last closing price per share of AgeX common stock on the NYSE American preceding the delivery of the notice from AgeX requesting the draw of funds that triggered the obligation to issue 2022 Warrants.

As of December 31, 2023, AgeX had issued to Juvenescence 2022 Warrants to purchase a total of 294,482 shares of AgeX common stock, of which 2022 Warrants to purchase 53,980 shares of AgeX common stock were issued during the year ended December 31, 2023. The exercise prices of the 2022 Warrants issued through December 31, 2023 ranged from $20.75 per share to $30.94 per share representing the market closing price of AgeX common stock on the NYSE American on the one day prior to delivery of the drawdown notices. However, 2022 Warrants to purchase a total of 164,889 shares of AgeX common stock were cancelled pursuant to the Merger Agreement and the remaining 2022 Warrants to purchase a total of 129,593 shares of common stock at prices ranging from $20.75 to $25.01 remain in effect. The number of shares issuable upon exercise of the 2022 Warrants and the exercise price per share are subject to adjustment upon the occurrence of certain events such as a stock split or reverse split or combination of the common stock, stock dividend, recapitalization or reclassification of the common stock, and similar events, and have been adjusted to give effect to the a 1 for 35.17 reverse stock split that AgeX implemented on March 14, 2024. See Note 7, Stockholders’ Equity/(Deficit). The 2022 Warrants will expire at 5:00 p.m. New York time three years after the date of issue. The expiration dates range from June 5, 2025 to April 3, 2026.

The audit report of Withum on our financial statements as of and for the years ended December 31, 2023, and December 31, 2022, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainties, audit scope or accounting principles.

In connection with the audits of AgeX’s financial statements for each of the two fiscal years ended December 31, 2023 and December 31, 2022, there were no disagreements with Withum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Withum, would have caused it to make a reference in connection with their opinion to the subject matter of the disagreement or reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

During the years ended December 31, 2023 and 2022, neither us nor anyone on our behalf consulted with Frazier & Deeter regarding (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our financial statements, and no written report or oral advice was provided to us by Frazier & Deeter that Frazier & Deeter concluded was an important factor considered by us in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a
35


disagreement, as that term is described in Item 304(a)(1)(iv) of Regulation S-K, or a reportable event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

The Board of Directors Recommends a Vote “FOR” Ratification of the Selection of Frazier & Deeter as Our Independent Registered Public Accountants
Audit Fees, Audit Related Fees, Tax Fees and Other Fees
The following table sets forth the aggregate fees billed to us during the fiscal years ended December 31, 2023 and 2022 by Withum:

(1)Audit Fees consist of fees billed for professional services rendered for the audit of our annual financial statements included in our Annual Report on Form 10-K, and review of interim financial statements included in our Quarterly Reports on Form 10-Q, and services that are normally provided by our independent registered public accountants in connection with statutory and regulatory filings or engagements.
(2)Audit-Related Fees relate to assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.” This category would include fees related to non-routine SEC filings.
Pre-Approval of Audit and Permissible Non-Audit Services
Our Audit Committee requires pre-approval of all audit and non-audit services. Other than de minimis services incidental to audit services, non-audit services shall generally be limited to tax services such as advice and planning and financial due diligence services. All fees for such non-audit services must be approved by the Audit Committee, except to the extent otherwise permitted by applicable SEC regulations. The Audit Committee may delegate to one or more designated members of the Audit Committee the authority to grant pre-approvals, provided such approvals are presented to the Audit Committee at a subsequent meeting. During 2023 and 2022, 100% of the fees paid to Withum were approved by the Audit Committee.
The Board of Directors proposes and recommends that the stockholders ratify the selection of the firm of Frazier & Deeter to serve as our independent registered public accountants for the fiscal year ending December 31, 2024. Approval of the selection of Frazier & Deeter to serve as our independent registered public accountants requires the affirmative vote of a majority of the shares of common stock present and voting on the matter at the Meeting, provided that the affirmative vote cast constitutes a majority of a quorum. Unless otherwise directed by the stockholders, proxies will be voted FOR approval of the selection of Frazier & Deeter to audit our financial statements.
We expect that a representative of Frazier & Deeter will be present at the Meeting, and will have an opportunity to make a statement if he or she so desires and may respond to appropriate questions from stockholders.
2024 INCENTIVE PLAN AMENDMENT PROPOSAL

Plan Background
In connection with the approval of the Merger, the stockholders of AgeX approved the 2024 Incentive Plan. The purpose of the 2024 Incentive Plan is to promote and closely align the interests of our employees, officers, non-employee directors, and other service providers and our stockholders by providing stock-based compensation. The objectives of the 2024 Incentive Plan are to attract and retain the best available personnel for positions of substantial responsibility and to motivate participants to optimize our profitability and growth through incentives that are consistent with our goals and that link the personal interests of participants to those of our stockholders.
36


The 2024 Incentive Plan currently authorizes the issuance of up to a total of 1,725,000 shares of our common stock. The 2024 Incentive Plan also currently provides that the maximum aggregate number of shares that may be issued under the Plan pursuant to Incentive Stock Options (as defined therein) shall not exceed 1,725,000 shares of common stock. As of October 22, 2024, there were approximately 72,208 shares remaining available for issuance under the 2024 Incentive Plan, 1,652,792 total stock options outstanding (with associated weighted average exercise price of $7.95 and weighted average remaining term of 9.74 years).

Capitalized terms used in this Proposal but not defined herein shall have the meaning ascribed to such terms in the 2024 Incentive Plan, as amended by 2024 Incentive Plan Amendment.

Purpose of the Plan and Reasons for the Proposed 2024 Incentive Plan Amendment

The 2024 Incentive Plan is designed to attract and retain nonemployee directors, employees, and consultants and reward them for making contributions to the success of the Company and its subsidiaries. These objectives are to be accomplished by making awards under the 2024 Incentive Plan and thereby providing Participants with a proprietary interest in the growth and performance of the Company. Stockholder approval of this Proposal will enable us to continue to grant equity awards to our employees, non-employee directors, and consultants at levels determined by the Board to be necessary to attract, retain and motivate the individuals who will be critical to our success in achieving our business objectives and thereby creating greater value for our stockholders. In addition to the crucial role we believe such grants play in attracting and retaining talented individuals, we believe that the equity compensation granted under the 2024 Incentive Plan also serves the important function of aligning the interests of Participants with our other stockholders and focusing such Participants on the long-term growth of the Company.

We are seeking stockholder approval of an amendment to the 2024 Incentive Plan to (i) increase the number of shares of common stock available for issuance thereunder (the “Share Reserve”) to 2,675,000, (ii) increase the number of shares that may be issued as Incentive Stock Options under the 2024 Incentive Plan to 2,675,000, (iii) provide that the Share Reserve will increase automatically on the first day of each fiscal year of the Company (each, a “Fiscal Year”) beginning with the 2026 Fiscal Year and ending on (and including) the first day of the 2034 Fiscal Year (each, an “Evergreen Date”), in each case, in an amount equal to 5% of the outstanding shares of common stock on the last day of the immediately preceding Fiscal Year (each, an “Evergreen Increase”); provided, however, that the Board may act to provide that there will be no Evergreen Increase for a Fiscal Year, or that the Evergreen Increase for such Fiscal Year will be a lesser number of shares of common stock; and (iv) to modify the Reversion of Shares Provisions (as defined below). In determining to propose the increases in shares set forth in the 2024 Incentive Plan Amendment, the Board has taken into consideration that the proposed increases would represent only a small percentage of the total shares of common stock outstanding and the desirability and importance of being able to continue to grant awards that are comparable to those of our peer companies

The form of the 2024 Incentive Plan reflecting the 2024 Incentive Plan Amendment is included as Annex A to this Proxy Statement with the revisions to the current 2024 Incentive Plan to be effected with deletions indicated with strike-throughs of the text and with additions of text indicated with a double underline boldface type. If our stockholders do not approve this proposal, the Company will continue to operate the 2024 Incentive Plan under its current provisions.


Summary Description of the 2024 Incentive Plan, as amended by the 2024 Incentive Plan Amendment

The following description of the material terms of the 2024 Incentive Plan, as amended by the 2024 Incentive Plan Amendment, is intended to be a summary only, and is qualified in its entirety by the full text of the Amended Plan which is included as Annex A to this Proxy Statement.

Plan Administration. The 2024 Incentive Plan is administered by the Compensation Committee of our Board. The Compensation Committee has broad authority, subject to the provisions of the 2024 Incentive Plan, to administer and interpret the 2024 Incentive Plan and awards granted thereunder. All decisions and actions of the Compensation Committee are final and binding.

Stock Subject to the 2024 Incentive Plan.
The 2024 Incentive Plan currently authorizes the issuance of up to a total of 1,725,000 shares of our common stock for the grant of awards under the 2024 Incentive Plan. The 2024 Incentive Plan currently provides that the number of shares of
37


common stock that may be issued as Incentive Stock Options under the 2024 Incentive Plan (the “ISO Limit”) shall not exceed 1,725,000 shares.
On cancellation, forfeiture, or expiration of an award under the current 2024 Incentive Plan, in whole or in part, the number of shares of common stock subject to such award will again become available for grant under the current 2024 Incentive Plan. Shares subject to an award under the current 2024 Incentive Plan will not again be made available for issuance or delivery thereunder if such shares are (a) shares tendered in payment of an option, (b) shares delivered or withheld by us to satisfy any tax withholding obligation, (c) shares covered by a stock-settled stock appreciation right or other awards that were not issued upon the settlement of the award, or (d) shares repurchased by us using option proceeds (the provisions of the current 2024 Incentive Plan described in this paragraph are referred to herein collectively as the “Reversion of Shares Provisions”).

If our stockholders approve the 2024 Incentive Plan Amendment:

(1)the Share Reserve would increase from 1,725,000 shares of common stock to 2,675,000 shares of common stock;
(2)the ISO Limit would increase from 1,725,000 shares of common stock to 2,675,000 shares of common stock;
(3)an “evergreen provision” would be added to provide that the Share Reserve will increase automatically on each Evergreen Date, in each case, in an amount equal to 5% of the outstanding shares of common stock on the last day of the immediately preceding Fiscal Year; provided, however, that the Board may act to provide that there will be no Evergreen Increase for a Fiscal Year, or that the Evergreen Increase for such Fiscal Year will be a lesser number of shares of common Stock; and
(4)the Reversion of Shares Provisions would be revised to provide that: (a) if an award or any portion thereof (i) expires or otherwise terminates without all of the shares covered by such award having been issued or (ii) is settled in cash (i.e., the participant receives cash rather than stock), such expiration, termination or settlement will not reduce (or otherwise offset) the Share Reserve; (b) if any shares of common stock issued pursuant to an award are forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition required to vest such shares in the participant, then the shares that are forfeited or repurchased will revert to and again become available for issuance under the Plan; and (c) any shares reacquired by the Company in satisfaction of tax withholding obligations on an award or as consideration for the exercise or purchase price of an award will again become available for issuance under the Plan.

Eligibility. Prospective or current members of our Board, employees (including executive officers), and other service providers of us and our affiliates are eligible to participate in the 2024 Incentive Plan. Only our employees may be granted Incentive Stock Options under the 2024 Incentive Plan. As of October 22, 2024, there were approximately fourteen individuals eligible to participate in the 2024 Incentive Plan.

Types of Awards

Stock Options. All options granted under the 2024 Incentive Plan will be evidenced by a written agreement with the participant, which provides, among other things, the term of the option, which may not generally exceed 10 years (or 5 years for grants of incentive stock options to ten percent shareholders), and other terms and conditions. The option exercise price for any option granted may not be less than the fair market value per share of our common stock on the grant date (or 110% of such fair market value for grants of incentive stock options to ten percent shareholders), as determined pursuant to the plan; provided that an option may be granted with a lower option exercise price if such option is granted pursuant to an assumption or substitution of another option that satisfied the provisions of section 409A or 424(a) of the Code, as applicable.

Stock Appreciation Rights. Stock appreciation rights may be granted alone or in conjunction with all or part of an option. Upon exercising a stock appreciation right, the participant is entitled to receive the amount equal to the number of shares of our common stock subject to the stock appreciation right that is being exercised multiplied by the excess by which the fair market value of our common stock at the time of exercise exceeds the exercise price of the stock appreciation right. All freestanding stock appreciation rights shall be granted subject to the same terms and conditions as applicable to options, including exercise price and term, as set forth above, and all tandem stock appreciation rights shall have the same exercise price as the option to which they relate. Stock appreciation rights may be settled in common stock, cash, restricted stock, or a combination thereof, at the Compensation Committee’s discretion.

38


Restricted Stock and RSUs. The 2024 Incentive Plan provides for awards of actual shares of common stock or hypothetical common stock units having a value equal to the fair market value of an identical number of shares of our common stock. The Compensation Committee will determine the restrictions and conditions applicable to each award of restricted stock or restricted stock units, which may include performance vesting conditions. Participants are entitled to receive all dividends and other distributions paid with respect to shares of common stock subject to restricted stock awards. Participants are entitled to receive dividend equivalents with respect to shares of common stock subject to restricted stock units only to the extent provided by the Compensation Committee.

Notwithstanding the above, dividends or dividend equivalents will be withheld with respect to restricted stock or restricted stock units that are subject to restrictions until the date the restrictions are released.

Transferability. Awards generally may not be sold, transferred for value, pledged, assigned or otherwise alienated or hypothecated by a participant other than by will or the laws of descent and distribution or upon approval by the Compensation Committee, to the extent provided in the award agreement or by subsequent consent granted by the Compensation Committee. Each option may be exercisable only by the participant during his or her lifetime.

Adjustments. In the event any change is made to the outstanding common stock as a result of any reorganization, reclassification, combination of shares, stock split, reverse stock split, spin-off, dividend or distribution of securities, property or cash (other than regular, quarterly cash dividends), or any other event or transaction that affects the number or kind of shares of common stock outstanding, then equitable and proportional adjustments will be made to the maximum number and class(es) of securities issuable under the 2024 Incentive Plan (including pursuant to incentive stock options). The terms of any outstanding award shall also be equitably adjusted by the Compensation Committee as to price, number, or kind of shares of common stock subject to such award, vesting, and other terms to reflect the foregoing events.

Change in Control. In the discretion of the Compensation Committee, any award agreement may provide, or the Compensation Committee may provide by amendment of any award agreement or otherwise, notwithstanding any provision of the 2024 Incentive Plan to the contrary, that in the event of a change in control (as defined in the 2024 Incentive Plan), options and/or stock appreciation rights will become immediately exercisable and/or the restrictions will be released immediately with respect to all or a specified portion of the shares of restricted stock or restricted stock units. In addition, in the event of a change in control, the Compensation Committee may, in its discretion and upon at least 10 days’ advance notice to the affected persons, cancel any outstanding awards and pay to the holders thereof, in cash or stock, or any combination thereof, the value of such awards based upon the price per share of common stock received or to be received by our other stockholders. In the case of any option or stock appreciation right with an exercise price that equals or exceeds the price paid for a share of common stock in connection with the change in control, the Compensation Committee may cancel the option or stock appreciation right without the payment of consideration therefor.

Clawback/Recoupment. Awards granted under the 2024 Incentive Plan will be subject to recoupment in accordance with any law, government regulation, or stock exchange listing requirement (or any policy we adopt pursuant to any such law, government regulation or stock exchange listing requirement).

Amendment and Termination. Our Board has the right to amend or terminate the 2024 Incentive Plan at any time, provided certain amendments may not be made without the approval of our stockholders in compliance with applicable law. No amendment to the 2024 Incentive Plan or an award or award agreement may be made that would materially impair the rights of the participant without such participant’s consent.
Duration of Plan. The 2024 Incentive Plan will expire by its terms on March 27, 2034.
Summary of U.S. Federal Income Tax Consequences

The material federal income tax consequences of the issuance and exercise of stock options and other awards under the 2024 Incentive Plan, as amended by the 2024 Incentive Plan Amendment, based on the current provisions of the Code and regulations, are as follows. Changes to these laws could alter the tax consequences described below. This summary assumes that all awards granted under the 2024 Incentive Plan are exempt from or comply with, the rules under Section 409A of the Code related to nonqualified deferred compensation.

Non-Statutory Options. An optionee generally will not recognize taxable income upon the grant of a non-statutory option. Rather, at the time of exercise of the option, the optionee will recognize ordinary income for income tax purposes in an amount equal to the excess, if any, of the fair market value of vested shares purchased over the exercise price. The
39


Company generally will be entitled to a tax deduction at such time and in the same amount, if any, that the optionee recognizes as ordinary income. The optionee’s tax basis in any shares received upon exercise of an option will be the exercise price paid plus the amount of compensation recognized by the participant as ordinary income (generally, fair market value of the shares on the date of exercise), and if the shares are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of such shares on the date of exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset of the optionee) depending upon the length of time such shares were held by the optionee.

Incentive Stock Options. Incentive stock options are eligible for favorable U.S. federal income tax treatment if certain requirements are satisfied. An incentive stock option must have an option price that is not less than the fair market value of the stock at the time the option is granted, and must not be exercisable after the expiration of 10 years from the date of grant; further restrictions apply to employees who are greater-than-10% shareholders. An employee granted an incentive stock option generally does not realize compensation income for U.S. federal income tax purposes upon the grant of the option. At the time of exercise of an incentive stock option, no compensation income is realized by the optionee other than tax preference income for purposes of the federal alternative minimum tax on individual income. If the shares acquired on exercise of an incentive stock option are held for at least two years after grant of the option and one year after exercise, then (i) the excess (if any) of the amount realized on the disposition over the exercise price will be taxed as capital gain and (ii) the amount (if any) by which the exercise price exceeds the amount realized upon the disposition will be treated as capital loss. If the shares acquired on exercise of an incentive stock option are disposed of within less than two years after grant or one year of exercise, the optionee will realize taxable compensation income in the year of the disposition equal to the lesser of (i) the excess of the fair market value of the shares on the date of exercise over the option price or (ii) the excess of the amount realized on the disposition over the option price, and the Company generally will be entitled to a tax deduction in such amount. Any additional amount realized will be taxed as capital gain.

Stock Grants. A participant generally will not be taxed upon the grant of stock awards subject to restrictions, but rather will recognize ordinary income in an amount equal to the fair market value of the shares at the time the shares are no longer subject to a “substantial risk of forfeiture” (within the meaning of the Code). The Company generally will be entitled to a deduction at the time when, and in the amount that, the participant recognizes ordinary income on account of the lapse of the restrictions. A participant’s tax basis in the shares will equal their fair market value at the time the restrictions lapse, and the participant’s holding period for capital gains purposes will begin at that time. Any cash dividends paid on the restricted shares before the restrictions lapse will be taxable to the participant as additional compensation (and not as dividend income). Under Section 83(b) of the Code, a participant may elect to recognize ordinary income at the time the shares are awarded in an amount equal to their fair market value at that time (less any amount paid by the participant for the shares), notwithstanding the fact that such shares are subject to restrictions and a substantial risk of forfeiture. If such an election is made, no additional taxable income will be recognized by such participant at the time the restrictions lapse, the participant will have a tax basis in the shares equal to their fair market value on the date of their award, and the participant’s holding period for capital gains purposes will begin at that time. The Company generally will be entitled to a tax deduction at the time when, and to the extent that, ordinary income is recognized by such participant.

Stock Units. The grantee recognizes no income until the issuance of the shares. At that time, the grantee must generally recognize ordinary income equal to the fair market value of the shares received. We generally will be entitled to a deduction in an amount equal to the ordinary income recognized by the grantee.

Stock Appreciation Rights (SARs). A participant who is granted a SAR generally will not recognize ordinary income upon receipt of the SAR. Rather, at the time of exercise of such SAR, the participant will recognize ordinary income for U.S. federal income tax purposes in an amount equal to the value of any cash received and the fair market value on the date of exercise of any shares received. The Company generally will be entitled to a tax deduction at such time and in the same amount, if any, that the participant recognizes as ordinary income. The participant’s tax basis in any shares received upon exercise of a SAR will be the fair market value of the shares on the date of exercise, and if the shares are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of such shares on the date of exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset of the participant) depending upon the length of time such shares were held by the participant.

Code Section 409A. Section 409A of the Code generally provides that any deferred compensation arrangement must satisfy specific requirements, both in operation and in form, regarding (1) the timing of payment, (2) the advance election of deferrals, and (3) restrictions on the acceleration of payment. Failure to comply with Section 409A may result in the early taxation (plus interest) to the participant of deferred compensation and the imposition of a 20% penalty on the participant
40


on such deferred amounts included in the participant’s income. We intend to structure awards under the 2024 Incentive Plan in a manner that is designed to be exempt from or comply with Section 409A.

Vote Required; Recommendation of the Board

The Board of Directors proposes and recommends that the stockholders approve the 2024 Incentive Plan Amendment to increase the number of shares available for issuance thereunder. Approval of the 2024 Incentive Plan Amendment to increase the number of shares available for issuance thereunder requires the affirmative vote of a majority of the shares of common stock present and voting on the matter at the Meeting, provided that the affirmative vote cast constitutes a majority of a quorum. Unless otherwise directed by the stockholders, proxies will be voted FOR approval of the 2024 Incentive Plan Amendment to increase the number of shares available for issuance thereunder.

ELIMINATING DUPLICATE MAILINGS
Serina has adopted a procedure called “householding.” Under this procedure, we may deliver a single copy of this Proxy Statement and our Annual Report to multiple stockholders who share the same address, unless we receive contrary instructions from one or more of the stockholders.

We will deliver separate copies of the Proxy Statement and Annual Report to each stockholder sharing a common address if they notify us that they wish to receive separate copies. If you wish to receive a separate copy of the Proxy Statement or Annual Report, you may contact us by telephone at (256) 327-9630, or by mail at 601 Genome Way, Suite 2001, Huntsville, Alabama 35806.
