The Board unanimously approved the recommendation of the Nominating and Governance Committee.

There are seven nominees for election to the Board at the 2024 Annual Meeting to serve until the next Annual Meeting of Stockholders and until their successors are duly elected and qualified. All of the nominees currently serve as directors of the Company. Proxies may not be voted with respect to more than seven individuals in the election of directors at the 2024 Annual Meeting.

Except where authority to vote for a director has been withheld, the proxies received pursuant to this solicitation will be voted "FOR" the nominees named below. If for any reason any nominee does not stand for election, such proxies will be voted in favor of the remainder of the nominees and may be voted for a substitute nominee in place of the nominee who did not stand.

Involvement by Officers or Directors in Certain Legal Proceedings

In October 2016, Nutroganics, Inc., a company in the natural foods industry, closed and filed for bankruptcy in the State of Delaware. Jay O. Wright, one of our executive officers and a director, was the secretary, treasurer and a director of Nutroganics, Inc. within two years of its bankruptcy. Prior to its bankruptcy, Nutroganics, Inc. traded in the over-the counter market under the ticker “NUTT”.

From May 2013 to May 2016, C. Thomas McMillen, a director of the Compay since October 12 2022, served as an independent director of RCS Capital Corporation ("RCS"). RCS filed a petition to reorganize under Chapter 11 of the Bankruptcy Code in January 2016 under a prepackaged plan with the consent of the majority of the creditors.

On or about December 29, 2014, a securities class action lawsuit was filed in the U.S. District Court, Southern District of New York against RCS Corporation and certain of its affiliates, officers, and directors, including C. Thomas McMillen, alleging false and misleading statements pertaining to the company’s financial position and future business prospects. The case is Weston v. RCS Capital Corporation, No. 14-cv-10136 (S.D.N.Y.). The case was settled in September 2017 without recourse to the independent directors of RCS Corporation, including Mr. McMillen.

Other than as noted in the preceding paragraphs, to our knowledge, our directors and executive officers have not been involved in any of the following events during the past ten years:

    1.    any bankruptcy petition filed by or against such person or any business of which such person was a general partner or executive officer either at the time of the bankruptcy or within two years prior to that time;

    2.    any conviction in a criminal proceeding or being subject to a pending criminal proceeding (excluding traffic violations and other minor offenses);

    3.    being subject to any order, judgment, or decree, not subsequently reversed, suspended, or vacated, of any court of competent jurisdiction, permanently or temporarily enjoining him or her from or otherwise limiting his or her involvement in any type of business, securities or banking activities or to be associated with any person practicing in banking or securities activities;

    4.    being found by a court of competent jurisdiction in a civil action, the SEC or the Commodity Futures Trading Commission to have violated a Federal or state securities or commodities law, and the judgment has not been reversed, suspended, or vacated;

    5.    being the subject of, or a party to, any Federal or state judicial or administrative order, judgment decree, or finding, not subsequently reversed, suspended, or vacated, relating to an alleged violation of any Federal or state securities or commodities law or regulation, any law or regulation respecting financial institutions or insurance companies, or any law or regulation prohibiting mail or wire fraud or fraud in connection with any business entity.

None of our directors, officers, affiliates, or any beneficial owner of 5% or more of our common stock, or any associate of such persons, is an adverse party in any material proceeding to, or has a material interest adverse to us, or any of our subsidiaries.

The Board recommends a vote "FOR" the election of Ms. Frost and Messrs. Alarie, Campbell, Champoux, Fuller, McMillen, and Wright as directors of the Company.

Corporate Governance

Overview

Our Nominating and Governance Committee has general oversight responsibility for governance of the Company, including the assessment and recruitment of new director candidates and the evaluation of director and Board performance. We monitor regulatory and other developments in the governance area with a view toward both legal compliance and maintaining governance procedures at the Company, consistent with what we consider to be best practices.

Corporate Governance Guidelines

Our Board has adopted Corporate Governance Guidelines that address, among other topics, the role and responsibilities of our directors, the structure and composition of our Board, and corporate governance policies and standards applicable to us in general. The Corporate Governance Guidelines are subject to periodic reviews and changes by our Nominating and Governance Committee and our Board. The full text of our Corporate Governance Guidelines are available without charge on the Corporate Governance portion of our website, http://www.castellumus.com.

Code of Ethics and Business Conduct

Our Board has adopted the Castellum, Inc. Code of Ethics and Business Conduct, which applies to all of our employees, officers, and directors, including our chief executive officer ("CEO"), our chief financial officer, and our other executive and senior financial officers. The full text of our Code of Ethics and Business Conduct may be accessed without charge on the Corporate Governance portion of our website, http://www.castellumus.com. We will disclose on the Corporate Governance portion of our website any amendment to our Code of Ethics and Business Conduct or any waiver granted to an executive officer or director under it. In the fiscal year ended December 31, 2023, no such waivers were sought or granted. The information found on the Company's website is not part of this Proxy Statement nor is it incorporated into any other filings the Company makes with the SEC.

Cybersecurity Oversight

Technology is a key component of our business operations, and cybersecurity is a significant consideration for the Company. The Company has a holistic firm-wide approach to risk management including material risks from cybersecurity threats. The firm's overall risk management activities are designed to identify, assess, report, and manage risks that could affect the firm in achieving its objectives and goals. This risk management framework operates across our business and integrates business operational resiliency and technology related risks such as cybersecurity threats. Although management is responsible for the firm's day to day cybersecurity operations, the Board has delegated the responsibility of overseeing the Company’s cybersecurity program to the Audit Committee.

Executive management and the Audit Committee receive periodic technology and cybersecurity updates led by the senior management from the Company's technology and information security teams. The Audit Committee receives information concerning the Company's preparation for a cyber incident, in order to understand how the Company would respond to a specific cybersecurity threat, along with the impact to the Company's operations. As part of this process, the Audit Committee engages in various activities to stay abreast of the cyber landscape, including briefings led by management experts.

Director Independence

Five of our seven current directors are independent under our Corporate Governance Guidelines and applicable NYSE American LLC ("NYSE American") listing standards. For a director to be considered independent, the Board must

PROXY STATEMENT 11

Corporate Governance

determine, after consideration of all relevant facts and circumstances, that the director has no material relationship with the Company directly, or as a partner, or officer of an organization that has a relationship with the Company. The independence criteria adopted by the Board are set forth in the Company's Corporate Governance Guidelines.

The Board has determined that Ms. Frost and Messrs. Alarie, Campbell, Champoux, and McMillen are independent under the criteria for directors established by the NYSE American and the independence criteria adopted by the Board. As a result, we currently have a majority of independent directors and satisfy the applicable rule of the NYSE American. Messrs. Fuller and Wright are employees of the Company and are not independent under the NYSE American listing standards or our Corporate Governance Guidelines, which can be found on the Corporate Governance portion of our website, http://www.castellumus.com.

Risk Oversight

Our full Board oversees the risk management activities designed and implemented by our management. Our Board executes its oversight responsibility for risk management both directly and through its committees. Our full Board also considers specific risk topics, including risks associated with our strategic plan, business operations, and capital structure. In addition, our Board regularly receives detailed reports from members of our senior management and other personnel that include assessments and potential mitigation of the risk and exposures involved with their respective area of responsibility.

As of October 12, 2022, the date on which our Registration Statement was deemed effective with the SEC, our Board has delegated to the Audit Committee oversight of our risk management process. Our other board committees, including the Compensation, Culture, and People Committee and the Nominating and Corporate Governance Committee also consider and address risk as they perform their respective committee responsibilities. All committees report to our full Board as appropriate, including when a matter rises to the level of a material or enterprise level of risk. In addition, our Board and its committees exercise their risk oversight function by regularly receiving and evaluating reports from management and by making inquiries of management concerning these reports, as appropriate. Furthermore, our Board and its committees receive reports from our auditors and other advisors and may meet in executive sessions with them.

Board Qualifications

Our Board has delegated to our Nominating and Governance Committee the responsibility for recommending to our Board the nominees for election as directors at the annual meeting of stockholders and for recommending persons to fill any vacancy on our Board. Our Nominating and Governance Committee selects individuals for nomination to our Board based on the following criteria. Nominees for director must:

•Possess fundamental qualities of intelligence, honesty, perceptiveness, good judgment, maturity, high ethics and standards, integrity, fairness, and responsibility.

Corporate Governance

Directors are selected on the basis of talent and experience. Diversity of background, including diversity of gender, race, ethnic, or geographic origin and age, and experience in the areas of technology, government contracting, or military experience, and other areas relevant to our activities are factors in the selection process. As a majority of our Board must consist of individuals who are independent, a nominee's ability to meet the independence criteria established by the NYSE American is also a factor in the nominee selection process.

For a better understanding of the qualifications of each of our directors, we encourage you to read their biographies set forth in this Proxy Statement.

Director Nominations

The Nominating and Governance Committee will consider candidates for director recommended by stockholders so long as the recommendations comply with our Amended and Restated Articles of Incorporation and Amended and Restated Bylaws and applicable laws, rules and regulations, including those promulgated by the SEC. The Nominating and Governance Committee will evaluate such recommendations in accordance with its charter, our Amended and Restated Bylaws, our Corporate Governance Guidelines, and the regular nominee criteria described above. Stockholders wishing to recommend a candidate for nomination should comply with the procedures set forth in the section below entitled "Frequently Asked Questions and Answers on Meeting and Voting - How do I recommend a director nominee?"

Gender Diversity Policy

Our Board of Directors is committed to nominating the best individuals to fulfill director and executive roles. Our Board has not adopted policies relating to the identification and nomination of women directors and executives as it does not believe that it is necessary in the case of our Company to have such written policies at this time. Our Board believes that diversity is important to ensure that board members and senior management provide the necessary range of perspectives, experience, and expertise required to achieve effective stewardship and management. We have not adopted a target regarding women on our Board or regarding women in executive officer positions as our Board believes that such arbitrary targets are not appropriate for our Company.

Director Term Limits

Our Board has not adopted policies imposing an arbitrary term or retirement age limit in connection with individuals serving as directors as it does not believe that such a limit is in the best interests of our Company. Our Nominating and Corporate Governance Committee will annually review the composition of our Board, including the age and tenure of individual directors. Our Board will strive to achieve a balance between the desirability of its members having a depth of relevant experience, on the one hand, and the need for renewal and new perspectives, on the other hand.

Attendance at Annual Meeting

It is suggested, by not required, that our directors attend our annual meetings of stockholders. The Company held its Annual Meeting for the fiscal year ending December 31, 2022 on May 25, 2023 at which all directors were present in person or virtually.

Related-Party Transaction Policy

PROXY STATEMENT 13

Corporate Governance

We adopted a written related person transactions policy pursuant to which related persons, namely our executive officers, directors, and principal stockholders, and their immediate family members, are not permitted to enter into certain transactions, or materially modify or amend an ongoing transaction, with us, in which the amount involved exceeds $120,000, without the consent of our Audit Committee or any other body of the Board comprised solely of independent directors. Any request for us to enter into or materially modify or amend certain such transactions is required to be presented to our Audit Committee for review, consideration, and approval. All of our directors and executive officers are required to report to our Secretary any such proposed related person transaction, who is required to provide notice of such proposed related person transaction to the Audit Committee. In approving or rejecting the proposed transaction, our Audit Committee will take into account, among other factors it deems appropriate, whether the proposed related person transaction is on terms at least as favorable as terms generally available to an unaffiliated third party under the same or similar circumstances, the extent of the related person’s interest in the transaction and, if applicable, the impact on a director’s independence. Under the policy, if we should discover related person transactions that have not been approved, our Audit Committee will be notified and will determine the appropriate action, including ratification, rescission, or amendment of the transaction.

Board Leadership Structure

Our Amended and Restated Bylaws and our Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board, and CEO in accordance with its determination that utilizing one or the other structure is in the best interests of our Company. Mr. Champoux was appointed Chair of the Board in October 2022.

As Chair of the Board, Mr. Champoux’s key responsibilities include facilitating communication between our Board and management, assessing management’s performance, managing board members, preparation of the agenda for each board meeting, acting as chair of board meetings and meetings of our Company’s stockholders and managing relations with stockholders, other stakeholders, and the public. The Company does not have a lead independent director, because the Chair is an independent director.

We will take steps to ensure that adequate structures and processes are in place to permit our Board to function independently of management. The directors are able to request at any time a meeting restricted to independent directors for the purposes of discussing matters independently of management and are encouraged to do so should they feel that such a meeting is required.

Board Meetings and Committees

For the fiscal year ended December 31, 2023, there were five regularly scheduled or special meetings of the Board and the Board acted by unanimous written consent in lieu of a meeting on three occasions.

Since October 12, 2022 the standing committees of our Board consist of an Audit Committee, a Compensation, Culture, and People Committee, and a Nominating and Governance Committee, each of which has the composition and responsibilities described below. Each of the committees reports to our Board as they deem appropriate and as our Board may request. Members serve on these committees for such term or terms as our Board may determine or until their earlier resignations or death. Each committee of our Board has a written committee charter that set out the mandate of such committee, including the responsibilities of the chair of such committee.

In 2023, each director attended at least 75% of the meetings of the Board and the committees on which he or she serves. The full text of each committee charter is available without charge on the Corporate Governance portion of our website, http://www.castellumus.com. From time to time, our Board may also establish other special committees when necessary to address specific issues.

Corporate Governance

Advisory Board

In January 2020, the Board established an advisory board of business professionals (the "Advisory Board") who each bring unique knowledge, skills, and perspective which augment the knowledge and skills of the Board in order to guide the organization more effectively. The Advisory Board most recently consisted of six individuals including Trey Blalock, F. Austin Branch, Alan Lynn, James Moran, Craig Nixon, and Chuck Zingler. Prior to serving on the Board, Ms. Frost and Messrs. Campbell, Champoux, and McMillen were each members of the Advisory Board.

As consideration for serving on the Advisory Board the Company will issue to each advisor, at his or her election, either (i) 16,000 shares of the Company’s common stock or (ii) 48,000 stock options to purchase common stock of the Company. In the event the advisor elects to receive compensation in the form of stock options, the terms of the stock option agreement shall be consistent with those issued to other consultants under the Company’s 2021 Stock Incentive Plan.

During the second quarter of 2023, management evaluated the contributions made by the members of the Advisory Board during the prior twelve month period and their respective knowledge, skills, perspective, and relationships relative to those of the five independent members who joined the Board in the prior fiscal year. After due consideration and given the Company's financial condition, management recommended to the members of the Compensation, Culture, and People Committee that further payments to the Advisory Board be discontinued and that the Advisory Board be disbanded effective as of June 30, 2023. The members of the Compensation, Culture, and People Committee unanimously approved management's recommendation and each Advisory Board member received 8,000 shares of the Company's common stock for services on the Advisory Board from January 1, 2023 through June 30, 2023.

Communications with Directors

Stockholders, or other interested parties, who wish to contact our Board may send written correspondence, in care of our Corporate Secretary to Castellum, Inc., 1934 Old Gallows Road, Suite 350, Vienna, VA 22182. Communications may be addressed to an individual director, to the non-management directors as a group, or to the Board as a whole, marked as confidential or otherwise. Communications not submitted confidentially, which are addressed to directors that discuss business or other matters relevant to the activities of our Board, will be preliminarily reviewed by the office of the Secretary and then distributed either in summary form or by delivering a copy of the communication. Communications marked as confidential will be distributed, without review by the office of the Secretary, to the director, or group of directors, to whom they are addressed. With respect to other correspondence received by the Company that is addressed to one or more directors, the Board has requested that the following items not be distributed to directors because they generally fall into the purview of management, rather than the Board: junk mail and mass mailings, service complaints and inquiries, resumes, and other forms of job inquiries, solicitations for charitable donations, surveys, business solicitations, and advertisements.

Audit Committee

During the fiscal year ended December 31, 2023, there were five regularly scheduled or special meetings of the Audit Committee and the Audit Committee did not act by unanimous written consent in lieu of a meeting.

Mr. McMillen serves as chair of our Audit Committee. Our Board has determined that Mr. McMillen qualifies as an “audit committee financial expert,” as such term is defined in Item 407(d)(5) of Regulation S-K under the Securities Act of 1933, as amended (the "Securities Act"). This designation does not impose on him any duties, obligations, or liabilities that are greater than are generally imposed on members of our Audit Committee and our Board.

Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds. Hedging transactions may permit a director, officer, or employee to continue to own our securities obtained through employee benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the director, officer, or employee may no longer have the same objectives as our other stockholders. Therefore, directors, officers, and

employees are prohibited by our Insider Trading Policy, which was amended and adopted by the Board on November 9, 2023, from engaging in any such transactions.

Policy on Stock Pledging

Our Insider Trading Policy prohibits employees, officers, and directors from pledging Company securities as collateral for a loan.

Compensation Clawback Policy

On November 9, 2023 our Board adopted revisions to our Compensation Clawback Policy to comply with the NYSE American listing standards and the final rules adopted by the SEC regarding the clawback requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act. In the event we are required to prepare an accounting restatement of our financial results as a result of a material noncompliance by us with any financial reporting requirement under the federal securities laws, we will have the right to use reasonable efforts to recover from any current or former executive officer who received incentive compensation (whether cash or equity) from us during the three-year period preceding the date on which we were required to prepare the accounting restatement, any excess incentive compensation awarded as a result of the misstatement. As of October 12, 2022, this policy is administered by the Compensation, Culture, and People Committee of our Board. The policy is effective for financial statements for periods beginning on or after January 1, 2022.

Executive Compensation

(4) Messrs. Fuller and Wright participated in a group term life plan and other benefits that are generally available to salaried employees. Messrs. Wright and Ives also participated in the Company's 401(k) plan and received matching company contributions. From January to June 2023, Mr. Fuller received a stipend of $4,000 per month to cover the cost of health insurance premiums, which was reduced to $2,500 in July 2023. Mr. Wright received a stipend of $4,000 per month to cover the cost of health insurance premiums. During 2022 Messrs. Fuller and Wright each received a monthly stipend of $4,000 per month to cover the cost of health insurance premiums.

Decisions on the executive compensation program are made by the Compensation, Culture, and People Committee of the Board and, as necessary, approved by the entire Board of Directors. Compensation for the NEOs was determined in 2023 by employment agreements which were entered into prior to the Company's listing on the NYSE American and establishment of the Compensation, Culture, and People Committee by the Board. In March 2024 the members of the Compensation, Culture, and People Committee retained the services of an independent compensation consultant to review, evaluate, and make recommendations concerning the Company's executive compensation structure, including metrics to achieve bonus and performance based equity, as well as reviewing the level of compensation for the members of the Board. It is the intention of management and the Committee that the renewal or extension of these legacy agreements will be aligned with the executive compensation structure being developed by the Company and will be materially different from the existing agreements. The members of the Compensation, Culture, and People Committee is currently reviewing appropriate future compensation arrangements with the Company's officers, including the NEOs, and are working with management to create a comprehensive compensation structure which will permit all executive compensation to be aligned with the Company's existing compensation policies and philosophies, which are designed to align compensation with its business objectives and the creation of stockholder value, while enabling it to attract, motivate, and retain individuals who contribute to its long-term success.

Decisions regarding executive compensation reflect a belief that our executive compensation program must be competitive in order to attract and retain highly competent executive officers as well as include a significant element of pay for performance. The Compensation, Culture, and People Committee seeks to implement these compensation policies and philosophies by linking a significant portion of the Company’s executive officers’ cash compensation to the achievement of annual performance objectives and by providing a portion of their compensation as both annual and long-term incentive compensation in the form of equity awards. Further, the Compensation, Culture, and People Committee seeks to tie our executive compensation levels to the compensation practices of our peer companies and the shareholder returns achieved by those peer companies by setting our relative executive compensation percentile levels comparable to the relative shareholder return percentile level achieved by the Company as compared to its peer companies.

Compensation for the Company’s executive officers has three primary components: base salary, an annual cash incentive bonus, and long-term equity-based incentive compensation.

Employment Agreements; Potential Payments Upon Termination or Change in Control

On April 1, 2020 we entered into employment agreements with each of Mr. Fuller and Mr. Wright. The employment agreements have a term of four years and provide a base salary of $30,000 per month (the “Executives' Base Salary”). The Executives' Base Salary will increase to $40,000 per month upon the Company achieving an annualized revenue run rate of $75,000,000 or greater. The Executives' Base Salary shall be payable in regular installments in accordance with the Company’s general payroll practices.

Additionally, Messrs. Fuller and Wright shall be eligible to earn a performance bonus (the “Executives' Performance Bonus”). The Company shall pay to Messrs. Fuller and Wright a cash bonus equal to the lesser of (i) one percent (1%) of the trailing twelve (12) month revenues of each business acquired by the Company during the term of the employment agreement, or (ii) four percent (4%) of the trailing twelve month earnings before interest, depreciation, and amortization ("EBITDA") of each business acquired by the Company during the term of the employment agreement, provided that, for a bonus to be due, such acquisition must be accretive to the Company on both a revenue per share and EBITDA per share basis. In addition to the cash bonus, Messrs. Fuller and Wright shall be entitled to receive .05 of one warrant to purchase shares of the Company’s common stock for each one dollar ($1) of revenue acquired in any acquisition completed by the

PROXY STATEMENT 25

Executive Compensation

Company during the term of the employment agreement. Each warrant shall have a seven (7) year term and shall have an exercise price equal to the price used to value shares of the Company’s common stock issued as part of the purchase price consideration, or in the event shares of common stock are not issued, the trailing thirty (30) day moving average closing price of the Company’s common stock. Messrs. Fuller and Wright earned an additional bonus of (i) $50,000 and 500,000 warrants to purchase the Company’s common stock with an exercise price of $2.00 upon the Company’s common stock trading on the NYSE American, which occurred in 2023, and (ii) $125,000 and 1,250,000 warrants to purchase the Company’s common stock with an exercise price of $2.40 upon the Company joining the Russell 3000 and/or Russell 2000 stock index(ices). The agreements entitle Messrs. Fuller and Wright to receive various employee benefits generally made available to other officers and senior executives of the Company.

If Messrs. Fuller and Wright terminate their employment with the Company without good reason or their employment is terminated (i) as a result of their death, (ii) by the Company after a determination of a disability, or (iii) by the Company for cause, the Company will pay or provide Messrs. Fuller and Wright (a) those benefits as required by law, (b) for any earned but unpaid Base Salary, (c) for the reimbursement of unreimbursed business expenses, and (d) for the payment of unpaid Performance Bonus for any fiscal year ended prior to the termination date. In addition, if Messrs. Fuller’s or Wright's employment is terminated by the Company without cause or by him for good reason, then Messrs. Fuller and Wright shall be entitled to receive the Executives' Base Salary for a period equal to the earlier of (x) twelve (12) months following the termination date and (y) the date on which the employment period would have expired had the employment period not been terminated earlier by the Company without cause or by Messrs. Fuller or Wright without good reason (the “Executives' Severance Payments”). In order to qualify for the Executives' Severance Payments the executive must execute and not revoke a mutual release agreement in a form reasonably acceptable to the Company. The employment agreements contain customary confidentiality restrictions, non-competition covenants, non-disparagement covenants, and non-solicitation covenants with respect to our employees, consultants, and customers.

In the second quarter of 2023, Messrs. Fuller and Wright agreed to defer a portion of their respective salary and the full amount of the bonus earned under the terms of their respective employment agreements until such time as the Company's cash flow improved. At December 31, 2023, Messrs. Fuller and Wright each had $32,500 in deferred salary and $29,320 in deferred bonus.

On March 13, 2024, the Company entered into an agreement to extend the term of the agreements with Messrs. Fuller and Wright until June 30, 2024 to permit the Compensation, Culture, and People Committee additional time to retain an independent compensation consultant to review, evaluate, and make recommendations concerning the Company's executive compensation structure, including metrics to achieve bonus and performance based equity.

On July 1, 2021 we entered into an employment agreement with Glen Ives to serve as our Chief Growth Officer and Navy division chief executive officer. The employment agreement has a term of four years. The agreement provides for an annual base salary of $300,000 (the “Ives Base Salary”). The Ives Base Salary will increase as follows: (i) $30,000 per month upon the Navy division reaching an annualized revenue run rate of $60,000,000 or greater and EBITDA margin of no less than 8.5%; and (ii) $40,000 per month upon the Navy division reaching an annualized revenue run rate of $100,000,000 or greater and EBITDA margin of no less than 9.0%. The Ives Base Salary shall be payable in regular installments in accordance with the Company’s general payroll practices.

In addition, Mr. Ives shall be eligible to earn a bonus (the “Ives Performance Bonus”) at the discretion of the Board of the Company with a target bonus amount for each year of the agreement, as follows: (a) year one, 25% of the Ives Base Salary, (b) year two, 35% of the Ives Base Salary, (c) year three, 50% of the Ives Base Salary, and (d) year four, 100% of the Ives Base Salary. The Board shall consider the growth and success of the Navy division and the overall performance of Mr. Ives as the two key factors in evaluating the appropriate amount of the Ives Performance Bonus. The Board may make an additional bonus, outside of the targeted amount, in its sole discretion.

As an additional incentive for entering into the employment agreement, Mr. Ives was granted 1,500,000 stock options to purchase the Company’s common stock at an exercise price of $1.60 per share. The price amount is subject to adjustment in the event of a forward or reverse stock split, stock dividend, or other similar mechanism. The stock options shall vest as follows: (i) 750,000 shall vest ratably over the first 48 months of employment with the Company, and (ii) 750,000

shall vest based upon performance. For the performance-based options, (a) 250,000 shall vest upon the closing of the acquisition of Specialty Services, Inc. (which occurred in 2022), (b) 250,000 shall vest upon the Navy division achieving $25 million in revenue and $2.5 million in EBIDTA in any 12 month period (which occurred in 2023), and (c) 250,000 shall vest upon the Company achieving $100 million in revenue run rate based on quarterly performance. All unvested time-based options shall vest upon the sale of control of the Company. Unvested performance-based options shall not vest upon the sale of control of the Company unless the sale results in a price to stockholders of at least $8.00 per share.

If Mr. Ives terminates his employment with the Company or his employment is terminated (i) as a result of his death, (ii) by the Company after a determination of a disability, or (iii) by the Company for cause, the Company will pay or provide Mr. Ives (a) those benefits as required by law, (b) for any earned but unpaid Ives Base Salary, (c) for the reimbursement of unreimbursed business expenses, and (d) for the payment of unpaid Ives Performance Bonus for any fiscal year ended prior to the termination date. In addition, if Mr. Ives’ employment is terminated by the Company without cause or by him for good reason, then Mr. Ives shall be entitled to receive the Ives Base Salary for a period equal to the earlier of (x) twelve (12) months following the termination date and (y) the date on which the employment period would have expired had the employment period not been terminated earlier by the Company without cause (the “Ives Severance Payments”). In order to qualify for the Ives Severance Payments Mr. Ives must execute a mutual release agreement in a form reasonably acceptable to the Company. The employment agreement contains customary confidentiality restrictions, non-competition covenants, and non-solicitation covenants with respect to our employees, consultants, and customers.

Audit Committee Report

With respect to Castellum, Inc.'s ("Castellum" or the "Company") financial reporting process, the management of Castellum is responsible for establishing and maintaining internal controls and preparing consolidated financial statements. Castellum's independent registered public accounting firm, RSM US LLP (“RSM”) is responsible for auditing these financial statements. It is the responsibility of the Audit Committee to oversee these activities. The Audit Committee does not itself prepare financial statements or perform audits, and its members are not auditors or certifiers of Castellum's financial statements. We have relied, without independent verification, on management's representation that the financial statements have been prepared with integrity and objectivity and in conformity with US GAAP and on the representations of RSM included in its audit of Castellum's consolidated financial statements.

We have reviewed and discussed the audited consolidated financial statements for the fiscal year ended December 31, 2023 with Castellum's management and with RSM, including the results of the independent registered public accounting firm's audit of Castellum's financial statements. We have also discussed with RSM all matters required to be discussed by the Standards of the Public Company Accounting Oversight Board ("PCAOB") for communication with audit committees, under which RSM must provide us with additional information regarding the scope and results of its audit of Castellum's consolidated financial statements.

We have also received and reviewed the written disclosures and the letter from RSM required by applicable requirements of the PCAOB regarding RSM's communications with the Audit Committee concerning independence, and have discussed with RSM its independence from Castellum, as well as any relationships that may impact RSM's objectivity and independence.

Based on our review of the matters noted above and our discussions with Castellum's management and independent registered public accountants, we recommended to the Board of Directors that the audited consolidated financial statements be included in Castellum's Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the Securities and Exchange Commission.

Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee of our Board has appointed RSM US LLP ("RSM") as our independent registered public accounting firm for the fiscal year ending December 31, 2024. We are asking our stockholders to ratify the selection of RSM as our independent registered public accounting firm. Although ratification is not required by our Amended and Restated Bylaws or otherwise, we are submitting the election of RSM to our stockholders for ratification as a matter of good corporate practice and because we value our stockholders' views on our independent registered public accounting firm. In the event that our stockholders fail to ratify the selection, the Audit Committee will review its future selection of independent auditors. Even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interest of Castellum, Inc. and our stockholders. Representatives of RSM are expected to be present at the 2024 Annual Meeting, and they will have the opportunity to make a statement if they so desire and to respond to appropriate questions.

The following table presents fees for professional audit services and other services provided to Castellum, Inc. by RSM for the fiscal years ended December 31, 2023 and December 31, 2022.

	2023		2022
Audit Fees (1)	$	379,650	$	302,950
Audit-Related Fees	-		282,730
Tax Fees	89,560		106,023
All Other Fees	57,500		-

(1)Audit fees consist of fees billed for professional services rendered in connection with the audit of our annual financial statements, review of our quarterly financial statements, and services that are normally provided by our independent registered public accounting firm in connection with statutory and regulatory filings or engagements for those fiscal years.

Pre-Approval Policies and Procedures

Pursuant to the Audit Committee Charter, Audit Committee policy and the requirements of law, the Audit Committee pre-approves all audit and permitted non-audit services that may be provided by our independent registered public accounting firm. This pre-approval applies to audit services, audit-related services, tax services, and other services. In some cases, the full Audit Committee provides pre-approval for specific services, subject to a specific dollar threshold. In other cases, the chair of the Audit Committee has the delegated authority from the Audit Committee to pre-approve services up to a specific dollar threshold, and the chairperson then reports such pre-approvals to the full Audit Committee at its next meeting. For the fiscal year ended December 31, 2023, all fees paid to RSM have been approved by the Audit Committee.

The Board recommends a vote "FOR" the ratification of the appointment of RSM as our independent registered public accounting firm for the fiscal year ended December 31, 2024.

Proposal No. 3
Approve an Amendment to the Castellum, Inc. 2021 Stock Incentive Plan

General

On November 9, 2023, our Board adopted an amendment (the "Amendment") to the Castellum, Inc. 2021 Stock Incentive Plan (the "Plan") which increases the aggregate number of shares of common stock available for issuance under the Plan by 3,500,000 to a total of 6,000,000, subject to the approval of the Amendment to the Plan by our stockholders at the 2024 Annual Meeting. Other than the increase in the number of shares of common stock available for issuance under the Plan, there are no other changes to the Plan.

Within this Proposal 3, we refer to the Plan, as amended by the Amendment, as the Amended Plan. The Amended Plan is attached hereto as Exhibit A.

Reasons for the Amended Plan

The Company views its use of stock-based awards as an essential part of the Company’s compensation program and as an important element in achieving the program’s goals of attracting and retaining key employees and directors, providing them with additional incentive to increase the long-term value of the Company, and linking their financial interests with those of the Company’s stockholders. The Company also believes that stock-based awards motivate employees and non-employee directors to create stockholder value because the value they realize from these awards is based in large part on the Company’s common stock price performance.

The Company also uses stock-based awards to compensate certain consultants to the business and the Company believes this is an important element in aligning these consultants and service providers to the goals of the Company. It motivates the consultants and service providers to give a maximum effort to share in the returns for their services.

The increase in the number of the shares available and annual increase in shares under the Amended Plan is to ensure that we have the continued ability to make awards under the Amended Plan. We expect that the requested increase in the number of shares would likely be sufficient to provide Amended Plan awards forat least an additional three years, at which time the Company would seek stockholder approval for the award of any additional shares under the Amended Plan. Expectations regarding future share usage could be impacted by a number of factors such as: (i) the future performance of our stock price; (ii) hiring and promotion activity at the executive level; (iii) the rate at which shares are returned to the Amended Plan reserve upon awards' expiration or forfeiture without the issuance of the underlying shares; (iv) factors involved in acquiring other companies; and (v) other factors. While we believe that the assumptions used are reasonable, future share usage may differ from current expectations.

If stockholder approval of the share increase is not obtained, there will be insufficient shares available under the Amended Plan to make annual awards and to provide grants to new hires in future years. In this event, the Company would be required to revise its compensation philosophy and formulate other cash-based programs to attract, retain, and compensate key employees and non-employee directors. The Company would also have to use cash for some consultants and service providers to achieve its goals.

Effects of the Amendment to the Plan

The Amendment to the Plan reflects the proposed increase of 3,500,000 shares of common stock available for issuance under the Plan from 2,500,000 shares to 6,000,000 shares. As a result of the Amendment to the Plan, there will be an increase in the total number of shares of common stock reserved for issuance under the Amended Plan. This will provide

PROXY STATEMENT 35

the Company with the ability to grant additional awards than are currently available under the Amended Plan to eligible recipients, including employees, directors, consultants, and advisors.

The issuance in the future of awards under the Amended Plan consisting of full value awards and options to purchase shares of common stock may have the effect of diluting the earnings per share and book value per share, as well as the stock ownership and voting rights, of the holders of the currently outstanding shares of common stock. The effective increase in the number of authorized but unissued shares of common stock which may be issued as awards under the Amended Plan may be construed as having an anti-takeover effect by permitting the issuance of shares to purchasers who might oppose a hostile takeover bid or oppose any efforts to amend or repeal certain provisions of the Company’s amended and restated articles of incorporation or amended and restated bylaws. Holders of the common stock have no preemptive or other subscription rights.

Material Terms of the Plan

The following is a summary of the Plan. It is qualified by reference to the full text of the Plan, which was attached as Exhibit 10.9 to the Form S-1 that we filed with the SEC on September 2, 2022 (File No. 333-267249) and which was declared effective by the SEC on October 12, 2022.

Purpose. The Plan is intended to promote the best interests of the Company and its stockholders by (i) assisting the Company and its affiliates in the recruitment and retention of persons with ability and initiative, (ii) providing an incentive to such persons to contribute to the growth and success of the Company's businesses by affording such persons equity participation in the Company, and (iii) associating the interests of such persons with those of the Company and its affiliates and stockholders.Toward these objectives, the Plan provides for the grant of stock options, stock bonus awards, restricted stock awards, stock appreciation rights, restricted stock unit awards, and other stock awards to employees, consultants, and eligible directors, subject to the conditions set forth in the Plan.

Administration. The Plan is administered by the Board or any committee of the Board to which the Board has delegated any responsibility for the implementation, interpretation, or administration of the Plan (the "Committee").

Eligibility. Nonqualified stock options and stock awards may be granted to any eligible person selected by the Board or the Committee.Incentive Stock Options may be granted only to employees of the Company or a parent or subsidiary company.

Common Stock Subject to the Plan. Subject to an adjustment for changes in the Company's capital structure, the maximum aggregate number of shares of common stock that may be (i) issued under the Plan pursuant to the exercise of options, (ii) issued pursuant to stock bonus awards, restricted stock awards and other stock awards, and (iii) covered by stock appreciation rights and restricted stock unit awards is two million five hundred thousand (2,500,000) shares.

Withholding of Taxes. The Company shall have the right, before any certificate for any common stock is delivered, to deduct or withhold from any payment owed to a participant any amount that is necessary in order to satisfy any withholding requirement that the Company believes in good faith believes is imposed upon it in connection with Federal, state, or local taxes, including transfer taxes, as a result of the issuance of, or lapse of restrictions on, such common stock, or otherwise require such participant to make provision for payment of any such withholding amount.

Transfer Restrictions and Repurchase Rights. Except for certain exempt transactions, no person who shall have acquired shares of common stock or shall have any right to acquire shares of common stock under the Plan shall sell, assign, pledge or otherwise transfer any such shares of common stock or any right or interest therein (including, without limitation, any Option) (such shares or right or interest therein, collectively, the "Securities"), whether voluntarily, involuntarily, by operation of law, by gift or otherwise, without the prior written consent of the Corporation, evidenced by a writing approved by the Board. Transfers exempt from this restriction include: (i) a person’s transfer of any or all Securities held either during such person’s lifetime or on death by will or intestacy (1) to such person’s immediate family, (2) to any custodian or trustee for the account or the benefit of such person or such person’s immediate family, or (3) to any limited partnership or limited liability company with respect to which the ownership interests are wholly owned by the person, members of such person’s immediate family or any trust for the account or benefit of such person

36 Castellum, Inc.

or such person’s immediate family; (ii) a person’s bona fide pledge or mortgage of any Securities with a commercial lending institution that creates a mere security interest, provided that any subsequent transfer of such Securities by such institution shall be subject to the terms of the Plan; (iii) a person’s transfer of any or all of such person’s Securities to the Company (or the Company’s assignee); and (iv) a person’s transfer of any or all of such person’s Securities in connection with a transaction subject to a merger, consolidation, assets or other corporate transaction of the Company or in compliance with such person’s obligations under an agreement with the Company compelling the person to sell such Securities.

Shares of common stock acquired under the Plan shall also be subject to such forfeiture conditions, rights of repurchase, rights of first refusal, and other transfer restrictions as the Board or Committee may determine.Such restrictions shall be set forth in the applicable stock option agreement or stock award agreement and, unless otherwise provided in the stock option agreement or stock award agreement, shall apply to any dividends paid with respect to such shares.Such restrictions shall apply in addition to any restrictions otherwise applicable to holders of shares of common stock generally.

Compliance With Law and Approval of Regulatory Bodies. No stock option or stock award shall be exercisable, no common stock shall be issued, no certificates for shares of common stock shall be delivered, and no payment shall be made under this Plan except in compliance with all applicable federal and state laws and regulations (including, without limitation, withholding tax requirements), any listing agreement to which the Company is a party, and the rules of all domestic stock exchanges or quotation systems on which the Corporation’s shares may be listed.The Company shall have the right to rely on an opinion of its counsel as to such compliance.Any share certificate issued to evidence common stock when a stock award is granted or for which a stock option or stock award is exercised may bear such legends and statements as the Board or Committee may deem advisable to assure compliance with federal and state laws and regulations.No stock option or stock award shall be exercisable, no stock award shall be granted, no common stock shall be issued, no certificate for shares shall be delivered, and no payment shall be made under this Plan until the Company has obtained such consent or approval as the Board or Committee may deem advisable from regulatory bodies having jurisdiction over such matters.

General Provisions. Neither the adoption of the Plan, its operation, nor any documents describing or referring to this Plan (or any part thereof) shall (i) confer upon any individual any right to continue in the employ or service of the Company or an affiliate, (ii) in any way affect any right and power of the Company or an affiliate to change an individual’s duties or terminate the employment or service of any individual at any time with or without assigning a reason therefor, or (iii) except to the extent the Board or Committee grants a stock option or stock award to such individual, confer on any individual the right to participate in the benefits of the Plan.

The proceeds received by the Company from the sale of common stock pursuant to this Plan shall be used for general corporate purposes. The Plan, insofar as it provides for grants, shall be unfunded, and the Company shall not be required to segregate any assets that may at any time be represented by grants under this Plan.Any liability of the Company to any person with respect to any grant under this Plan shall be based solely upon any contractual obligations that may be created pursuant to the Plan.No such obligation of the Company shall be deemed to be secured by any pledge of, or other encumbrance on, any property of the Company. It is the intent of the Company that all awards under the Plan that constitute “non-qualified deferred compensation” within the meaning of Internal Revenue Service ("IRS") Code Section 409A will satisfy the requirements of that section, and that all awards under the Plan that can qualify for an exemption from the definition of “non-qualified deferred compensation” under that section, including but not limited to stock options, stock appreciation rights, and restricted stock awards, will do so unless the Board or Committee has determined otherwise. Accordingly, the terms of the Plan and award agreements shall be interpreted in a manner consistent with IRS Code Section 409A and regulations thereunder.

Amendment and Termination. The Board may amend or terminate this Plan from time to time; provided, however, that stockholder approval shall be required for any amendment that (i) increases the aggregate number of shares of common stock that may be issued under the Plan or (ii) changes the class of employees eligible to receive incentive stock options,

PROXY STATEMENT 37

except as specifically permitted by the Plan, stock option agreement or stock award agreement or as required to comply with any applicable law, regulation or rule, no amendment shall, without a participant’s consent, adversely affect any rights of such participant under any stock option or stock award outstanding at the time such amendment is made; provided, however, that an amendment that may cause an incentive stock option to become a non-qualified stock option, and any amendment that is required to comply with the rules applicable to incentive stock options, shall not be treated as adversely affecting the rights of the participant.Stockholder approval shall also be required for any amendment if such approval is required by the terms of any applicable law, regulation, or rule, including, without limitation, any stock market or securities on which the common stock is publicly traded. Each such amendment shall be subject to the approval of the stockholders of the Company within twelve (12) months of the date such amendment is adopted by the Board.

Plan Effective Date and Duration. The Plan will become effective upon adoption by the Board, subject to the approval within twelve (12) months by the stockholders holding a majority of the voting power of shares of the Company entitled to vote thereon. Unless previously terminated, the Plan will terminate ten (10) years after the earlier of (i) the date the Plan is adopted by the Board, or (ii) the date the Plan is approved by the stockholders, except that stock options and stock awards that are granted under the Plan prior to its termination will continue to be administered under the terms of the Plan until the options and stock awards terminate or are exercised.

The Board recommends a vote "FOR" the amendment to the Castellum, Inc. 2021 Stock Incentive Plan to increase the aggregate shares available for issuance to 6,000,000.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

If your shares are registered directly in your name with our transfer agent, Nevada Agency and Transfer Company, you are considered the stockholder of record with respect to those shares, and the Notice of Internet Availability of Proxy Materials was sent directly to you by us. As a stockholder of record, you may vote your shares in person at the 2024 Annual Meeting or by proxy as described below.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the "beneficial owner" of shares held in street name. The Notice and, upon your request, the proxy materials were forwarded to you by your broker, bank, or other nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your bank, broker, or other nominee on how to vote your shares by following their instructions for voting.

How can I vote my shares?

If you are a stockholder of record, you may vote:

•Via the Internet. You may vote by proxy via the Internet by following the instructions found on the proxy card.

•By Telephone. You may vote by proxy by calling the toll-free number found on the proxy card.

•By Mail. You may vote by proxy by filling out the proxy card and returning it in the envelope provided.

•In Person. You may vote in person at the 2024 Annual Meeting. You must request a ballot when you arrive.

Internet and telephone voting will be available 24 hours a day and will close at 11:59 p.m. Eastern Time on Tuesday, May 28, 2024.

If you are a beneficial owner of shares held in street name, you should have received from your bank, broker, or other nominee instructions on how to vote or instruct the broker to vote your shares, which are generally contained in a "voting instruction form" sent by the broker, bank, or other nominee. Please follow their instructions carefully. Beneficial owners generally may vote:

•Via the Internet. You may vote by proxy via the Internet by following the instructions on the voting instruction form provided to you by your broker, bank, or other nominee.

•By Telephone. You may vote by proxy by calling the toll-free number found on the voting instruction form provided to you by your broker, bank, or other nominee.

•By Mail. You may vote by proxy by filling out the voting instruction form and returning it in the envelope provided to you by your broker, bank, or other nominee .

•In Person. If you wish to vote in person, you must obtain a legal proxy from the organization that holds your shares. Please contact that organization for instructions on how to obtain a legal proxy to you from your broker, bank, or other nominee.

If you received more than one Notice of Internet Availability of Proxy Materials or proxy card, then you hold shares of Castellum's common stock in more than one account. You should vote via the Internet, by telephone, by mail, or in person for all shares held in each of your accounts.

Questions and Answers

If I submit a proxy, how will it be voted?

When proxies are properly signed, dated, and returned, the shares represented by the proxies will be voted in accordance with the instructions of the stockholder. If no specific instructions are given, you give authority to Mark C. Fuller and Jay O. Wright to vote the shares in accordance with the recommendations of our Board as described above. If any director nominee is not able to serve, proxies will be voted in favor of the other nominee and may be voted for a substitute nominee, unless our Board chooses to reduce the number of directors serving on our Board. If any matters not described in this Proxy Statement are properly presented at the 2024 Annual Meeting, then the proxy holders will use their own judgment to determine how to vote the shares. If the 2024 Annual Meeting is adjourned, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy.

Can I change my vote or revoke my proxy?

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy before it is exercised by:

•Written notice to our Corporate Secretary;

•Timely delivery of a valid, later-dated proxy or a later-dated vote by telephone or on the Internet; or

•Voting in person at the 2024 Annual Meeting.

If you are a beneficial owner of shares held in street name, you should follow the instructions of your bank, broker, or other nominee to change or revoke your voting instructions. You may also vote in person at the 2024 Annual Meeting if you obtain a legal proxy as described above.

Can I attend the 2024 Annual Meeting?

You are invited to attend the 2024 Annual Meeting if you are a registered stockholder or a beneficial owner as of the record date or if you hold a valid proxy for the 2024 Annual Meeting. In order to enter the 2024 Annual Meeting, you must be prepared to present photo identification acceptable to us, such as a valid driver's license or passport. If you are a beneficial owner, you will need to provide proof of beneficial ownership on the record date, such as a recent account statement showing your ownership, a copy of the voting instruction card provided by your broker, trustee, or nominee, or other similar evidence of ownership.

What constitutes a quorum at the 2024 Annual Meeting?

The presence, in person or by proxy, of the holders of at least 50% of the outstanding shares of stock entitled to vote at the 2024 Annual Meeting must be present or represented to conduct business at the 2024 Annual Meeting. You will be considered part of the quorum if you return a signed and dated proxy card, if you vote by telephone or Internet, or if you attend the 2024 Annual Meeting.

Abstentions and withhold votes are counted as "shares present" at the 2024 Annual Meeting for purposes of determining whether a quorum exists. Proxies submitted by banks, brokers, or other holders of record holding shares for you as a beneficial owner that do not indicate a vote for some of or all the proposals because that holder does not have voting authority and has not received voting instructions from you (so-called "broker non-votes") are also considered "shares present" for purposes of determining whether a quorum exists. If you are a beneficial owner, these holders are permitted to vote your shares on the ratification of the appointment of our independent registered public accounting firm, even if they do not receive voting instructions from you.

What is the voting requirement to approve each of the proposals?

Provided that there is a quorum, the voting requirements are as follows:

PROXY STATEMENT 41

Questions and Answers

Proposal	Vote Required	Broker Discretionary Voting Allowed?
Election of directors	Plurality of votes cast	No
Ratification of appointment of independent registered public accounting firm	Majority of votes cast	Yes
Approval of an amendment to the Castellum, Inc. 2021 Stock Incentive Plan to increase the aggregate number of shares reserved for issuance under the plan to 6,000,000	Majority of votes cast	Yes

What is the impact of abstentions, withhold votes, and broker non-votes?

Abstentions, withheld votes, and broker non-votes are considered "shares present" for the purpose of determining whether a quorum exists, but will not be considered votes properly cast at the 2024 Annual Meeting and will have no effect on the outcome of the vote for each of the proposals. Under the rules of the NYSE American LLC, without voting instructions from beneficial owners, brokers will have discretion to vote on the ratification of the appointment of the independent registered public accounting firm and the approval of an amendment to increase the shares available for issuance under the Castellum, Inc. 2021 Stock Incentive Plan, but not on the election of directors. Therefore, in order for your voice to be heard, it is important that you vote.

Who pays for the cost of this proxy solicitation?

We will pay all the costs of preparing, mailing, and soliciting the proxies. We will ask brokers, banks, voting trustees, and other nominees and fiduciaries to forward the proxy materials to the beneficial owners of our common stock and to obtain the authority to execute proxies. We will reimburse them for their reasonable expenses upon request. In addition to mailing proxy materials, our directors, officers, and employees may solicit proxies in person, by telephone, or otherwise. These individuals will not be specially compensated.

Where can I find the voting results of the 2024 Annual Meeting?

We will announce preliminary voting results, and if available, final voting results at the 2024 Annual Meeting.

Why did I receive a Notice of Internet Availability of Proxy Materials rather than a full set of proxy materials?

In accordance with the SEC rules, we have elected to furnish our proxy materials, including this Proxy Statement and the Annual Report, primarily via the Internet rather than by mailing the materials to stockholders. The Notice of Internet Availability of Proxy Materials provides instructions on how to access our proxy materials on the Internet, how to vote, and how to request printed copies of the proxy materials. Stockholders may request to receive future proxy materials in printed form by following the instructions contained in the Notice of Internet Availability of Proxy Materials. We encourage stockholders to take advantage of the proxy materials on the Internet to reduce the costs and environmental impact of our 2024 Annual Meeting.

How can I obtain Castellum's Form 10-K and other financial information?

PROXY STATEMENT 4

Board may delegate administrative authority with respect to Eligible Persons who are not subject to Section 16 of the Exchange Act to a committee of other than Non-Employee Directors.

4. Eligibility

a. Eligibility for Awards. Nonqualified Stock Options and Stock Awards may be granted to any Eligible Person selected by the Committee. Incentive Stock Options may be granted only to employees of the Corporation or a Parent or Subsidiary.

b. Eligibility of Consultants.

c. Substitution Awards. The Committee may make Stock Awards and may grant Options under the Plan by assumption, substitution or replacement of performance shares, phantom shares, stock awards, stock options, stock appreciation rights or similar awards granted by another entity (including an Affiliate), if such assumption, substitution or replacement is in connection with an asset acquisition, stock acquisition, merger, consolidation or similar transaction involving the Corporation (and/or its Affiliate) and such other entity (and/or its affiliate). Notwithstanding any provision of the Plan (other than the maximum number of shares of Common Stock that may be issued under the Plan), the terms of such assumed, substituted or replaced Stock Awards or Options shall be as the Committee, in its discretion, determines is appropriate.

5. Common Stock Subject to Plan

a. Share Reserve. Subject to adjustment as provided in Section 8, the maximum aggregate number of shares of Common Stock that may be (i) issued under this Plan pursuant to the exercise of Options, (ii) issued pursuant to Stock Bonus Awards, Restricted Stock Awards and Other Stock Awards, and (iii) covered by Stock Appreciation Rights and Restricted Stock Unit Awards is six million (6,000,000) shares. Notwithstanding the foregoing, subject to adjustment as provided in Section 8, no more than six million (6,000,000) shares of Common Stock may be issued pursuant to the exercise of Incentive Stock Options and Section 5.B shall apply to such limit to the extent permitted by Section 422 of the Code and regulations thereunder.

b. Reversion of Shares. If an Option or Stock Award is terminated, expires or becomes unexercisable, in whole or in part, for any reason, the unissued or unpurchased shares of Common Stock (or shares subject to an unexercised Stock Appreciation Right or unsettled Restricted Stock Unit Award) which were subject thereto shall become available for future grant under the Plan. Shares of Common Stock that have been actually issued under the Plan shall not be returned to the share reserve for future grants under the Plan; except that shares of Common Stock issued pursuant to a Stock Award which are forfeited back to the Corporation rather than vesting, shall be returned to the share reserve for future grant under the Plan.

c. Source of Shares. Common Stock issued under the Plan may be shares of authorized and unissued Common Stock or shares of previously issued Common Stock that have been reacquired by the Corporation.

6. Options

a. Award. In accordance with the provisions of Section 4, the Committee will designate each Eligible Person to whom an Option is to be granted and will specify the number of shares of Common Stock covered by such Option. The Stock Option Agreement shall specify whether the Option is an Incentive Stock Option or Nonqualified Stock Option, the vesting schedule (if any) applicable to such Option and any other terms of such Option. No Option that is intended to be an Incentive Stock Option shall be invalid for failure to qualify as an Incentive Stock Option. Shares of Common Stock issued pursuant to an Option may, but need not, be subject to a vesting schedule and may, but need not, be subject to a share repurchase option in favor of the Corporation as determined by the Committee.

b. Exercise Price. The exercise price per share for Common Stock subject to an Option shall be determined by the Committee, but shall comply with the following:

PROXY STATEMENT 5

(i) The exercise price per share for Common Stock subject to a Nonqualified or Incentive Stock Option shall be determined by the Committee, provided that the exercise price per share for Common Stock shall not be less than one hundred percent (100%) of the Fair Market Value on the date of grant.

(ii) The exercise price per share for Common Stock subject to an Incentive Stock Option granted to a Participant who is or is deemed to be a Ten Percent Owner on the date such option is granted, shall not be less than one hundred ten percent (110%) of the Fair Market Value on the date of grant.

c. Maximum Option Period. The maximum period during which an Option may be exercised shall be determined by the Committee on the date of grant, except that no Option that is intended to be an Incentive Stock Option shall be exercisable after the expiration of ten (10) years from the date such Option was granted. In the case of an Incentive Stock Option that is granted to a Participant who is or is deemed to be a Ten Percent Owner on the date of grant, such Option shall not be exercisable after the expiration of five (5) years from the date of grant. The terms of any Option that is an Incentive Stock Option may provide that it is exercisable for a period less than such maximum period.

d. Maximum Value of Options which are Incentive Stock Options. To the extent that the aggregate Fair Market Value of the Common Stock with respect to which Incentive Stock Options granted to any person are exercisable for the first time during any calendar year (under all stock option plans of the Corporation and its Parent (if any) or any of its Subsidiaries) exceeds $100,000 (or such other amount provided in Section 422 of the Code), the Options are not Incentive Stock Options. For purposes of this section, the Fair Market Value of the Common Stock will be determined as of the time the Incentive Stock Option with respect to the Common Stock is granted. This section will be applied by taking Incentive Stock Options into account in the order in which they are granted.

e. Nontransferability. Options granted under this Plan which are intended to be Incentive Stock Options shall be nontransferable except by will or by the laws of descent and distribution and during the lifetime of the Participant shall be exercisable by only the Participant to whom the Incentive Stock Option is granted. If the Stock Option Agreement so provides or the Committee so approves, a Nonqualified Stock Option may be transferred by a Participant to the Participant’s children, stepchildren, grandchildren, spouse, one or more trusts for the benefit of such family members or a partnership in which such family members are the only partners; provided, however, that Participant may not receive any consideration for the transfer and such transfers are limited to the extent permitted by Rule 701 of the Securities Act and, if the Option is intended to satisfy the exemption under Section 25102(o) of the California Corporations Code, Rule 260.140.41(c) of Title 10 of the California Code of Regulations. The holder of a Nonqualified Stock Option transferred pursuant to this section shall be bound by the same terms and conditions that governed the Option during the period that it was held by the Participant. Except to the extent transferability of a Nonqualified Stock Option is provided for in the Stock Option Agreement or is approved by the Committee, during the lifetime of the Participant to whom the Nonqualified Stock Option is granted, such Option may be exercised only by the Participant. No right or interest of a Participant in any Option shall be liable for, or subject to, any lien, obligation, or liability of such Participant.

f. Vesting and Termination of Continuous Service. A Stock Option Agreement may provide for rules for vesting and termination of the Option on a termination of Continuous Service. Except as provided in a Stock Option Agreement (including an amendment of a Stock Option Agreement), the following rules shall apply:

(i) Subject to the rules of this paragraph, Options will vest as provided in the Stock Option Agreement. An Option will be exercisable only to the extent that it is vested on the date of exercise. Except to the extent the Committee explicitly determines otherwise with respect to an Option prior to the expiration or termination of the Option, vesting of an Option will cease on the date of the Participant’s termination of Continuous Service and the Option will be exercisable only to the extent the Option is vested on the date of termination of Continuous Service.

(ii) If the Participant’s termination of Continuous Service is for reason of death or Disability, the right to exercise the Option (to the extent vested) will expire on the earlier of (i) the close of business at Corporation headquarters on the date that is one (1) year after the date of the Participant’s termination of Continuous Service, or (ii) the expiration date under the terms of the Agreement. Until the expiration date, the Participant’s heirs, legatees or legal representative may exercise the Option, except to the extent the Option was previously transferred pursuant to Section 6.E.

(iii) If the Participant’s termination of Continuous Service is an involuntary termination without Cause or a voluntary termination (other than a voluntary termination described in Section 6.F.(iv)), the Option will expire on the earlier of (i) the close of business at Corporation headquarters on the date that is three (3) months after the date of the Participant’s termination of Continuous Service, or (ii) the expiration date under the terms of the Agreement. The Option, to the extent that it is vested, may be exercised prior to

PROXY STATEMENT 6

expiration. Notwithstanding any provision to the contrary, following termination of Continuous Service, a Participant shall not be entitled to exercise any unvested portion of an Option and shall have no right to receive any compensation with respect to such unvested portion. If the Participant’s termination of Continuous Service is an involuntary termination without Cause or a voluntary termination (other than a voluntary termination described in Section 6.F.(iv)) and the Participant dies after his or her termination of Continuous Service but before the right to exercise the Option has expired, the right to exercise the Option (to the extent vested) shall expire on the earlier of (i) the close of business at Corporation headquarters on the date that is one (1) year after the date of the Participant’s termination of Continuous Service or (ii) the date the Option expires under the terms of the Stock Option Agreement, and, until expiration, the Participant’s heirs, legatees or legal representative may exercise the Option, except to the extent the Option was previously transferred pursuant to Section 6.E.

(iv) If the Participant’s termination of Continuous Service is for Cause or is a voluntary termination at any time after an event which would be grounds for termination of the Participant’s Continuous Service for Cause, the right to exercise the Option shall expire as of the date of the Participant’s termination of Continuous Service.

g. Non-Exempt Employees. No Option, whether or not vested, granted to a Participant who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended (the “FLSA”), shall be first exercisable for any shares of Common Stock until at least six (6) months following the date of grant of the Option. Notwithstanding the foregoing, consistent with the provisions of the Worker Economic Opportunity Act, (i) upon the Participant’s death or Disability, (ii) upon a corporate transaction involving a change in corporate ownership which is described in Section 8.C. in which such Option is not assumed, continued, or substituted, or (iii) upon the Participant’s retirement (as such term may be defined in the Participant’s Option Agreement or in another applicable agreement or in accordance with the Corporation’s then current employment policies and guidelines), any such vested Options may be exercised earlier than six (6) months following the date of grant. The foregoing provision is intended to operate so that any income derived by a Participant who is a non-exempt employee in connection with the exercise or vesting of an Option will be excluded from his or her regular rate of pay for purposes of the FLSA.

h. Early Exercise. An Option may, but need not, include a provision whereby the Participant may elect at any time before the Participant’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Any unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Corporation (or its assignee) or to any other restriction the Board determines to be appropriate. The Corporation shall not be required to exercise its repurchase right until at least six (6) months (or such longer or shorter period of time required to avoid classification of the Option as a liability for financial accounting purposes) have elapsed following exercise of the Option unless specifically provided otherwise in the Option Agreement.

i. Exercise. An Option shall be exercised by completion, execution and delivery of notice (written or electronic) to the Corporation of the Option which states (i) the Option holder’s intent to exercise the Option, (ii) the number of shares of Common Stock with respect to which the Option is being exercised, (iii) such other representations and agreements as may be required by the Corporation and (iv) the method for satisfying any applicable tax withholding as provided in Section 9. Such notice of exercise shall be provided on such form or by such method as the Committee may designate, and payment of the exercise price shall be made in accordance with Section 6.J. Subject to the provisions of this Plan and the applicable Stock Option Agreement, an Option may be exercised to the extent vested in whole at any time or in part from time to time at such times and in compliance with such requirements as the Committee shall determine. A partial exercise of an Option shall not affect the right to exercise the Option from time to time in accordance with this Plan and the applicable Stock Option Agreement with respect to the remaining shares subject to the Option. An Option may not be exercised with respect to fractional shares of Common Stock.

j. Payment. Unless otherwise provided by the Stock Option Agreement, payment of the exercise price for an Option shall be made in cash or a cash equivalent acceptable to the Committee. Payment of all or part of the exercise price of an Option may also be made, (i) with the consent of the Committee, by surrendering shares of Common Stock to the Corporation, (ii) with the consent of the Committee, by a full-recourse promissory note, (iii) if the Common Stock is traded on an established securities market, the payment of the exercise price by a broker-dealer or by the Option holder with cash advanced by the broker-dealer if the exercise notice is accompanied by the Option holder’s written irrevocable instructions to deliver the Common Stock acquired upon exercise of the Option to the broker-dealer, or (iv) any other method acceptable to the Committee and provided for in the Stock Option Agreement. If Common Stock is used to pay all or part of the exercise price, the sum of the cash or cash equivalent and the Fair Market Value (determined as of the date of exercise) of the shares surrendered must not be less than the exercise price of the shares for which the Option is being exercised. If all or part of the exercise price is to be paid with a full-recourse promissory note, the par value of the Common Stock, if newly issued, shall be paid in

PROXY STATEMENT 7

cash or cash equivalents. The shares received upon exercise of the Option shall be pledged as security for payment of the principal amount of the promissory note and interest thereon and the interest rate payable under the terms of the promissory note shall not be less than the minimum rate (if any) required to avoid the imputation of additional interest under the Code. Subject to the foregoing, the Committee (at its sole discretion) shall specify the term, interest rate, amortization requirements (if any) and other provisions of such note.

k. Buyout Provisions. The Committee may at any time offer to buy out an Option previously granted for a payment in cash, shares of Common Stock or other property. Such buyout offer shall be on such terms and conditions as the Committee shall determine.

l. Stockholder Rights. No Participant shall have any rights as a stockholder with respect to shares subject to an Option until the date of exercise of such Option and the certificate for shares of Common Stock to be received on exercise of such Option has been issued by the Corporation.

m. Disposition and Stock Certificate Legends for Incentive Stock Option Shares. A Participant shall notify the Corporation of any sale or other disposition of Common Stock acquired pursuant to an Incentive Stock Option if such sale or disposition occurs (i) within two (2) years of the grant of an Option or (ii) within one (1) year of the issuance of the Common Stock to the Participant. Such notice shall be in writing and directed to the Secretary of the Corporation. The Corporation may require that certificates evidencing shares of Common Stock purchased upon the exercise of an Incentive Stock Option issued under the Plan be endorsed with a legend in substantially the following form:

THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED UPON EXERCISE OF AN INCENTIVE STOCK OPTION, AND THE CORPORATION MUST BE NOTIFIED IF THE SHARES SHALL BE TRANSFERRED BEFORE THE LATER OF THE TWO (2) YEAR ANNIVERSARY OF THE DATE OF GRANT OF THE OPTION OR THE ONE (1) YEAR ANNIVERSARY OF THE DATE ON WHICH THE OPTION WAS EXERCISED. THE REGISTERED HOLDER MAY RECOGNIZE ORDINARY INCOME IF THE SHARES ARE TRANSFERRED BEFORE SUCH DATE.

In the event of a Participant’s termination of Continuous Service, the Corporation may reacquire any or all of the shares of Common Stock held by the Participant which have not vested as of the date of termination under the terms of the Stock Bonus Award.

(iv) Transferability. Rights to acquire shares of Common Stock under the Stock Bonus Award shall be transferable by the Participant only upon such terms and conditions as are set forth in the Stock Award Agreement, as the Committee shall determine in its discretion, so long as Common Stock granted under the Stock Bonus Award remains subject to the terms of the Stock Award Agreement.

b. Restricted Stock Awards. Each Stock Award Agreement for a Restricted Stock Award shall be in such form and shall contain such terms and conditions as the Committee shall deem appropriate. The terms and conditions of the Stock Award Agreements for Restricted Stock Awards may change from time to time, and the terms and conditions of separate Restricted Stock Awards need not be identical, but each Restricted Stock Award shall include (through incorporation of the provisions hereof by references in the agreement or otherwise) the substance of each of the following provisions.

The purchase price of Common Stock acquired pursuant to the Restricted Stock Award shall be paid either: (i) in cash at the time of purchase; (ii) at the discretion of the Committee, according to a deferred payment or other similar arrangement with the Participant; or (iii) in any other form of legal consideration that may be acceptable to the Committee in its discretion; provided, however, that payment of the Common Stock’s “par value” shall not be made by deferred payment.

(iii) Vesting. Shares of Common Stock acquired under a Restricted Stock Award may, but need not, be subject to a share repurchase option in favor of the Corporation in accordance with a vesting schedule to be determined by the Committee.

(iv) Participant’s Termination of Service. In the event of a Participant’s termination of Continuous Service, the Corporation may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant which have not vested as of the date of termination under the terms of the Stock Award Agreement for such Restricted Stock Award.

(v) Transferability. Rights to acquire shares of Common Stock under a Restricted Stock Award shall be transferable by the Participant only upon such terms and conditions as are set forth in the Stock Award Agreement for such Restricted Stock Award, as the Committee shall determine in its discretion, so long as Common Stock granted under the Restricted Stock Award remains subject to the terms of the Stock Award Agreement.

c. Stock Appreciation Rights. Each Stock Award Agreement for Stock Appreciation Rights shall be in such form and shall contain such terms and conditions as the Committee shall deem appropriate. The terms and conditions of Stock Appreciation Rights may change from time to time, and the terms and conditions of separate Stock Appreciation Rights need not be identical, but each Stock Appreciation Right shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

(i) Benefit Provided. Each Stock Appreciation Right shall provide the Participant with the right to receive payment in cash or shares of Common Stock having a Fair Market Value, as designated in the Stock Award Agreement for such Stock Appreciation Rights, of an amount equal to the difference between the Fair Market Value of the Common Stock as of the date of grant of the Stock Appreciation Right and the Fair Market Value of the Common Stock on the date of exercise of such Stock Appreciation Right.

(ii) Tandem Awards. Stock Appreciation Rights may be granted either alone or in tandem with other awards, including Options, under the Plan.

(iii) Vesting. The Stock Award Agreement for a Stock Appreciation Right shall provide the vesting schedule applicable to such award and may, but need not, provide that shares of Common Stock acquired upon exercising a Stock Appreciation Right are subject to a repurchase option in favor of the Corporation.

(iv) Participant’s Termination of Service. In the event of a Participant’s termination of Continuous Service, the Corporation may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant which have not vested as of the date of termination under the terms of the Stock Appreciation Right.

(v) Transferability. Rights to acquire cash or shares of Common Stock under a Stock Appreciation Rights shall be nontransferable except by will or by the laws of descent and distribution and during the lifetime of the Participant shall be exercisable by only the Participant to whom the Stock Appreciation Rights are granted.

(vi) Non-Exempt Employees. No Stock Appreciation Right, whether or not vested, granted to a Participant who is a non-exempt employee for purposes of the FLSA, shall be first exercisable until at least six (6) months following the date of grant of the Stock Appreciation Right. Notwithstanding the foregoing, consistent with the provisions of the Worker Economic Opportunity Act, (i) upon the Participant’s death or Disability, (ii) upon a corporate transaction involving a change in corporate ownership which is described in Section 8.C. in which such Stock Appreciation Right is not assumed, continued, or substituted, or (iii) upon the Participant’s retirement (as such term may be defined in the Participant’s Stock Award Agreement or in another applicable agreement or in accordance with the Corporation’s then current employment policies and guidelines), any such vested Stock Appreciation Right may be exercised earlier than six (6) months

PROXY STATEMENT 9

following the date of grant. The foregoing provision is intended to operate so that any income derived by a Participant who is a non-exempt employee in connection with the exercise or vesting of a Stock Appreciation Right will be excluded from his or her regular rate of pay for purposes of the FLSA.

d. Restricted Stock Unit Awards. Each Stock Award Agreement for a Restricted Stock Unit Award shall be in such form and shall contain such terms and conditions as the Committee shall deem appropriate. The terms and conditions of Stock Award Agreements for Restricted Stock Unit Awards may change from time to time, and the terms and conditions of separate Restricted Stock Unit Awards need not be identical, but each Restricted Stock Unit Award shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

    (i)     Number of Shares; Consideration. Each Stock Award Agreement for a Restricted Stock Unit Award shall specify the number of shares of Common Stock that are subject to the Restricted Stock Unit Award and shall provide for the adjustment of such number in accordance with Section 8. A Restricted Stock Unit Award may be granted in consideration for services actually rendered or to be rendered to the Corporation or an Affiliate for its benefit.

    (ii)     Vesting. Each Award of Restricted Stock Units may, but need not, be subject to a vesting schedule and may, but need not, be subject to a share repurchase option in favor of the Corporation as determined by the Committee.

    (iii)     Settlement of Restricted Stock Units. Settlement of Restricted Stock Units shall be as provided in the Stock Award Agreement for such Restricted Stock Units. Settlement of the Restricted Stock Units may be made in the form of cash or whole shares of Common Stock or a combination thereof, as determined by the Committee in its sole discretion.

    (iv)     Participant’s Termination of Service. Except as otherwise provided in the Stock Award Agreement, in the event of a Participant’s termination of Continuous Service, any Restricted Stock Units held by such Participant which have not vested as of the date of termination under the terms of the Stock Award Agreement shall be forfeited.

    (v)     Transferability. Unless otherwise provided in the Stock Award Agreement, Restricted Stock Units may not be transferred other than by beneficiary designation, will or the laws of descent and distribution.

    (vi)     Stockholder Rights. No Participant shall have any rights as a stockholder with respect to shares covered by a Restricted Stock Unit Award until such Participant receives such shares upon settlement of the Restricted Stock Unit Award. A Participant shall have no rights under a Restricted Stock Unit Award other than those of a general creditor of the Corporation.

e. Other Stock Awards. The Committee may grant other forms of Stock Award under the Plan that are based in whole or in part on Common Stock or the value thereof. Subject to the provisions of the Plan, the Committee shall have authority in its sole discretion to determine the terms and conditions of such Other Stock Awards, including the number of shares (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards.

8. Changes in Capital Structure

a. No Limitations of Rights. The existence of outstanding Options or Stock Awards shall not affect in any way the right or power of the Corporation or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Corporation’s capital structure or its business, or any merger or consolidation of the Corporation, or any issuance of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Corporation, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

b. Changes in Capitalization. If the Corporation shall effect a subdivision, consolidation or reclassification of shares or other capital readjustment, a stock split, a reverse stock split, the payment of a dividend in stock of the Corporation, a spin-off, the payment of an extraordinary dividend or distribution in a form other than stock of the Corporation in an amount that has a material effect on the fair market value of the Common Stock, or other increase or reduction of the number of shares of the Common Stock outstanding, without receiving consideration therefore in money, services or property, then (i) the number, class, and per share price of shares of Common Stock subject to outstanding Options and Stock Awards hereunder and (ii) the number and class of shares then reserved for issuance under the Plan and the maximum number of shares for which awards may be granted to a Participant during a specified time period shall be appropriately and proportionately adjusted. The conversion of convertible securities of the Corporation shall not be treated as effected “without receiving consideration.” The Committee shall make such adjustments, and its determinations shall be final, binding and conclusive. Any such

PROXY STATEMENT 10

adjustment of an Option or Stock Award which is not subject to Section 409A of the Code shall be made in a manner which does not result in the Option or Stock Award being subject to Section 409A.

c. Merger, Consolidation, Asset Sale or Other Corporate Transaction. In the event that the Corporation is a party to a merger or other consolidation, in the event of a transaction providing for the sale of all or substantially all of the Corporation’s stock or assets, or in the event of such other corporate transaction, such as a separation or reorganization, outstanding Options and Stock Awards shall be subject to such treatment as the Board shall determine. Such treatment may include one or more of the following: (i) the continuation of the outstanding Options and Stock Awards by the Corporation, if the Corporation is a surviving entity; (ii) the assumption of outstanding Options and Stock Awards by the surviving or successor entity or its parent; (iii) the substitution by the surviving or successor entity or its parent of options or other awards with substantially the same terms for such outstanding Options and Stock Awards; (iv) exercisability of such outstanding Options and Stock Awards to the extent vested and exercisable under the terms of the Stock Option Agreement or Stock Award Agreement followed by the cancellation of such Options or Stock Award (whether or not then exercisable); or (v) settlement of the intrinsic value of the outstanding Options and Stock Awards to the extent vested and exercisable under the terms of the Stock Option Agreement or Stock Award Agreement, with payment made in cash, cash equivalents or other property as determined by the Committee (including cash, cash equivalents or other property subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Options and Stock Awards), and the cancellation of such Options and Stock Awards (whether or not then exercisable). The value of any property provided in the settlement shall be determined by the Board, and to extent permitted under Treasury Regulation Section 1.409A-3(i)(5)(iv) or otherwise without resulting in taxation under Section 409A of the Code, the Board may provide for the payment of the value of a cancelled Option or Stock Award to be made on a delayed basis in recognition of escrows, earn-outs, or other contingencies or holdbacks applicable to holders of Common Stock in connection with the transaction. In each case, the surviving, acquiring or successor entity or its parent may choose to assume or continue only a portion of an Option or Stock Award or substitute a similar award for only a portion of an Option or Stock Award, or may assume, continue or substitute some Options or Stock Awards and not others, and in all cases unvested Options or Stock Awards may be terminated without payment. The continuation, assumption or substitution of an Option which permits the exercise of the Option prior to the vesting of the shares of Common Stock subject to such Option (i.e., an “early exercise option”) may be made in a manner which permits exercise of such Option only to the extent it is vested. The actions under this paragraph shall be effected in a manner which does not result in an Option or Stock Award which is not subject to Section 409A of the Code being subject to taxation under Section 409A of the Code. During the pendency of a transaction subject to this Section 8.C., the Board shall have the discretion to suspend the rights of Participants to exercise outstanding Awards during a limited period of time preceding the closing of the transaction if appropriate to facilitate closing of the transaction.

d. Limitation on Adjustment. Except as previously expressly provided, neither the issuance by the Corporation of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Corporation convertible into such shares or other securities, nor the increase or decrease of the number of authorized shares of stock, nor the addition or deletion of classes of stock, shall affect, and no adjustment by reason thereof shall be made with respect to, the number, class or price of shares of Common Stock then subject to outstanding Options or Stock Awards.

9. Withholding of Taxes

The Corporation or an Affiliate shall have the right, before any certificate for any Common Stock is delivered, to deduct or withhold from any payment owed to a Participant any amount that is necessary in order to satisfy any withholding requirement that the Corporation or Affiliate in good faith believes is imposed upon it in connection with Federal, state, or local taxes, including transfer taxes, as a result of the issuance of, or lapse of restrictions on, such Common Stock, or otherwise require such Participant to make provision for payment of any such withholding amount. Subject to such conditions as may be established by the Committee, the Committee may permit a Participant to (i) have Common Stock otherwise issuable under an Option or Stock Award withheld to the extent necessary to comply with minimum statutory withholding rate requirements for supplemental income, (ii) tender back to the Corporation shares of Common Stock received pursuant to an Option or Stock Award in an amount not in excess of the maximum statutory tax rates in the Participant’s jurisdiction, (iii) deliver to the Corporation previously acquired Common Stock, (iv) have funds withheld from payments of wages, salary or other cash compensation due the Participant, or (v) pay the Corporation or its Affiliate in cash, in order to satisfy part or all of the obligations for any taxes required to be withheld or otherwise deducted and paid by the Corporation or its Affiliate with respect to the Option or Stock Award.

10. Transfer Restrictions And Repurchase rights

a. Transfer Restrictions. No person who shall have acquired shares of Common Stock or shall have any right to acquire shares of Common Stock under the Plan shall sell, assign, pledge or otherwise transfer (each, a “Transfer”) any such shares of Common Stock or any right or interest therein (including, without limitation, any

PROXY STATEMENT 11

Option) (such shares or right or interest therein, collectively, the “Securities”), whether voluntarily, involuntarily, by operation of law, by gift or otherwise, without the prior written consent of the Corporation, evidenced by a writing approved by the Board (the “Transfer Restriction”). The Transfer Restriction shall not apply to any of the following exempt Transfers:

(i) A person’s Transfer of any or all Securities held either during such person’s lifetime or on death by will or intestacy (1) to such person’s Immediate Family, (2) to any custodian or trustee for the account or the benefit of such person or such person’s Immediate Family, or (3) to any limited partnership or limited liability company with respect to which the ownership interests are wholly owned by the person, members of such person’s Immediate Family or any trust for the account or benefit of such person or such person’s Immediate Family;

(ii) A person’s bona fide pledge or mortgage of any Securities with a commercial lending institution that creates a mere security interest, provided that any subsequent Transfer of such Securities by such institution shall be subject to this Section;

(iii) A person’s Transfer of any or all of such person’s Securities to the Corporation (or the Corporation’s assignee); or

(iv) A person’s Transfer of any or all of such person’s Securities in connection with a transaction subject to Section 8.C. or compliance with such person’s obligations under an agreement with the Corporation compelling the person to sell such Securities (e.g., a drag-along);

provided that with respect to Transfers pursuant to subsections (i) and (ii) above, the Transferee shall receive and hold such Securities subject to the provisions of this Section 10.A and there shall be no further Transfer of such Securities except in accordance with this Section 10.A. The provisions of this Section 10.A may be waived with respect to any Transfer by the Board. The provisions of this Section 10.A shall terminate immediately prior to the date of the closing of a firm commitment underwritten public offering of the Corporation’s Common Stock pursuant to a registration statement filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act. Any Transfer or purported Transfer of Securities of the Corporation shall be null and void unless the terms, conditions and provisions of this Section 10.A are strictly observed and followed. The restrictions contained in this Section 10.A shall be in addition to any restrictions on transfer that may otherwise be applicable, including without limitation those contained in the Corporation’s bylaws, the Stock Option Agreement, Stock Award Agreement, or pursuant to applicable securities laws.

b. Corporation’s Right to Repurchase Shares. Shares of Common Stock acquired under the Plan shall also be subject to such forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Committee may determine. Such restrictions shall be set forth in the applicable Stock Option Agreement or Stock Award Agreement and, unless otherwise provided in the Stock Option Agreement or Stock Award Agreement, shall apply to any dividends paid with respect to such shares. Such restrictions shall apply in addition to any restrictions otherwise applicable to holders of shares of Common Stock generally.

11. Compliance with Law and Approval of Regulatory Bodies

a. General Requirements. No Option or Stock Award shall be exercisable, no Common Stock shall be issued, no certificates for shares of Common Stock shall be delivered, and no payment shall be made under this Plan except in compliance with all applicable federal and state laws and regulations (including, without limitation, withholding tax requirements), any listing agreement to which the Corporation is a party, and the rules of all domestic stock exchanges or quotation systems on which the Corporation’s shares may be listed. The Corporation shall have the right to rely on an opinion of its counsel as to such compliance. Any share certificate issued to evidence Common Stock when a Stock Award is granted or for which an Option or Stock Award is exercised may bear such legends and statements as the Committee may deem advisable to assure compliance with federal and state laws and regulations. No Option or Stock Award shall be exercisable, no Stock Award shall be granted, no Common Stock shall be issued, no certificate for shares shall be delivered, and no payment shall be made under this Plan until the Corporation has obtained such consent or approval as the Committee may deem advisable from regulatory bodies having jurisdiction over such matters.

b. Voting and Dividend Rights. Except as provided in the award agreement, the holders of shares of Common Stock acquired under the Plan shall have the same voting, dividend and other rights as the Corporation’s other stockholders. A Stock Bonus Agreement or Restricted Stock Agreement, however, may require that the holders of shares of Common Stock invest any cash dividends received in additional shares of Common Stock. Such additional shares shall be subject to the same conditions and restrictions as the award with respect to which the dividends were paid.

PROXY STATEMENT 12

c. Participant Representations. The Committee may require that a Participant, as a condition to receipt or exercise of a particular award, execute and deliver to the Corporation a written statement, in form satisfactory to the Committee, in which the Participant represents and warrants that the shares are being acquired for such person’s own account, for investment only and not with a view to the resale or distribution thereof. The Participant shall, at the request of the Committee, be required to represent and warrant in writing that any subsequent resale or distribution of shares of Common Stock by the Participant shall be made only pursuant to either (i) a registration statement on an appropriate form under the Securities Act of 1933, which registration statement has become effective and is current with regard to the shares being sold, or (ii) a specific exemption from the registration requirements of the Securities Act of 1933, but in claiming such exemption the Participant shall, prior to any offer of sale or sale of such shares, obtain a prior favorable written opinion of counsel, in form and substance satisfactory to counsel for the Corporation, as to the application of such exemption thereto.

d. Foreign Participants. In order to facilitate the making of any award or combination of awards under the Plan, the Committee may provide for such special terms for awards to Participants who are foreign nationals, or who are employed by the Corporation or any Affiliate outside of the United States, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Moreover, the Committee may approve such supplements to, or amendments, restatements or alternative versions of, the Plan, including "sub-plans" to the Plan, as it may consider necessary or appropriate for such purposes without thereby affecting the terms of the Plan as in effect for any other purpose, provided that no such supplements, amendments, restatements, alternative versions or sub-plans shall include any provisions that are inconsistent with the Plan, unless the Plan may be amended to eliminate such inconsistency without further approval by the stockholders of the Corporation.

12. General Provisions

a. Effect on Employment and Service. Neither the adoption of this Plan, its operation, nor any documents describing or referring to this Plan (or any part thereof) shall (i) confer upon any individual any right to continue in the employ or service of the Corporation or an Affiliate, (ii) in any way affect any right and power of the Corporation or an Affiliate to change an individual’s duties or terminate the employment or service of any individual at any time with or without assigning a reason therefor or (iii) except to the extent the Committee grants an Option or Stock Award to such individual, confer on any individual the right to participate in the benefits of the Plan.

b. Use of Proceeds. The proceeds received by the Corporation from the sale of Common Stock pursuant to this Plan shall be used for general corporate purposes.

c. Unfunded Plan. The Plan, insofar as it provides for grants, shall be unfunded, and the Corporation shall not be required to segregate any assets that may at any time be represented by grants under this Plan. Any liability of the Corporation to any person with respect to any grant under this Plan shall be based solely upon any contractual obligations that may be created pursuant to this Plan. No such obligation of the Corporation shall be deemed to be secured by any pledge of, or other encumbrance on, any property of the Corporation.

d. 409A Compliance.    It is the intent of the Corporation that all awards under the Plan that constitute “nonqualified deferred compensation” within the meaning of Code Section 409A will satisfy the requirements of that section, and that all awards under the Plan that can qualify for an exemption from the definition of “nonqualified deferred compensation” under that section, including but not limited to Options, Stock Appreciation Rights and Restricted Stock Awards, will do so unless the Committee has determined otherwise. Accordingly, the terms of the Plan and Award Agreements shall be interpreted in a manner consistent with Code Section 409A and regulations thereunder.

e. Rules of Construction. Headings are given to the Sections of this Plan solely as a convenience to facilitate reference, and shall not be used in interpreting, construing or enforcing any provision hereof. The reference to any statute, regulation, or other provision of law shall be construed to refer to any amendment to or successor of such provision of law.

f. Electronic Delivery and Execution. Any reference herein to a “written” agreement or document shall include any agreement or document delivered electronically or posted on the Corporation’s intranet (or other shared electronic medium controlled by the Corporation to which the Participant has access). Documents may also be accepted by e-signature or other means of electronic indications of acceptance as specified by the Committee.

g. Choice of Law. The Plan and, except to the extent that a Stock Option Agreement or Stock Award Agreement otherwise provides, all Stock Option Agreements and Stock Award Agreements entered into under the Plan shall be governed by and interpreted under the laws of the state of incorporation of Corporation excluding (to

PROXY STATEMENT 13

the greatest extent permissible by law) any rule of law that would cause the application of the laws of any jurisdiction other than the laws of the jurisdiction of incorporation of the Corporation.

13. Amendment and Termination

The Board may amend or terminate this Plan from time to time; provided, however, that stockholder approval shall be required for any amendment that (i) increases the aggregate number of shares of Common Stock that may be issued under the Plan or (ii) changes the class of employees eligible to receive Incentive Stock Options, except as specifically permitted by the Plan, Stock Option Agreement or Stock Award Agreement or as required to comply with any applicable law, regulation or rule, no amendment shall, without a Participant’s consent, adversely affect any rights of such Participant under any Option or Stock Award outstanding at the time such amendment is made; provided, however, that an amendment that may cause an Incentive Stock Option to become a Nonqualified Stock Option, and any amendment that is required to comply with the rules applicable to Incentive Stock Options, shall not be treated as adversely affecting the rights of the Participant. Stockholder approval shall also be required for any amendment if such approval is required by the terms of any applicable law, regulation, or rule, including, without limitation, any stock market or securities on which the Common Stock is publicly traded. Each such amendment shall be subject to the approval of the stockholders of the Corporation within twelve (12) months of the date such amendment is adopted by the Board.

14. Effective Date of Plan and Duration of Plan

a. The Plan shall become effective as of November 9, 2023 upon adoption by the Board, subject to approval within twelve (12) months by the stockholders holding of a majority of the voting power of shares of the Corporation entitled to vote thereon. Unless and until the plan has been approved by the stockholders of the Corporation, no Option or Stock Award may be exercised, and no shares of Common Stock may be issued under the Plan. In the event that the stockholders of the Corporation shall not approve the Plan within such twelve (12) month period, the Plan and any previously granted Option or Stock Award shall terminate.

b. Unless previously terminated, the Plan will terminate ten (10) years after the earlier of (i) the date the Plan is adopted by the Board, or (ii) the date the Plan is approved by the stockholders, except that Options and Stock Awards that are granted under the Plan prior to its termination will continue to be administered under the terms of the Plan until the Options and Stock Awards terminate or are exercised.
