Pyxis Oncology, Inc.

Director Independence

As our common stock is listed on the Nasdaq, the Company's determination of the independence of directors and director nominees is premised on the definition of “independent director” contained in Nasdaq Rule 5605(a)(2). In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and governance committees be independent. A director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Additionally, compensation committee members and audit committee members must satisfy additional independence criteria under Nasdaq and SEC rules.

Our Board has undertaken a review of the independence of each director and director nominee and has considered whether any of the foregoing has a material relationship with the Company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our Board determined that, with the exception of our President, Chief Executive Officer and Chief Medical Officer, Dr. Sullivan, each member of our Board and each director nominee is an “independent director” as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of Nasdaq. In making these determinations, our Board reviewed and discussed information provided by the directors and director nominees with regard to each director’s or director nominee's business and personal activities and relationships as they may relate to us and our management, including the beneficial ownership of our common stock by each non-employee director and the transactions involving such non-employee directors described in the section titled “Certain Relationships and Related Person Transactions”.

Leadership Structure of the Board of Directors

Our bylaws and corporate governance guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer and/or the implementation of a lead director in accordance with its determination that utilizing one or the other structure would be in the best interests of our company. Mr. Flavin currently serves as our Chair of the Board.

As a general policy, our Board believes that separation of the positions of Chair of the Board and Chief Executive Officer reinforces the independence of the board of directors from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board as a whole. As such, Dr. Sullivan serves as our President, Chief Executive Officer and Chief Medical Officer while Mr. Flavin serves as our Chair of the Board but is not an officer of our company. The Board has concluded that our current leadership structure is appropriate at this time. However, our Board continues to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Board of Directors’ Role in Risk Oversight

One of the key functions of the Board is informed oversight of our risk management process. Our Board does not have a standing risk management committee, but rather administers this oversight function directly through the board of directors as a whole, as well as through its standing committees that address risks inherent in their respective areas of oversight. In particular, the Board is responsible for monitoring and assessing strategic risk exposure. Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. Our Audit committee also oversees and continuously monitors our cybersecurity risk profile and assesses potential risk exposure. For more information on our management of cybersecurity risks, please refer to Item 1C, “Cybersecurity,” in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 18, 2025. Our Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our external audit function. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines and risks associated with our governance practices, including those related to emerging topics such as human capital analysis and disclosures and our environmental, sustainability and governance efforts, progress and disclosures. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Our Research & Development Committee provides guidance to management and the Board on matters relating to our research and development efforts and product pipeline.

Evaluation of the Board of Directors

The Board evaluates its performance and the performance of its committees and individual directors on an annual basis through an evaluation process administered by the Nominating and Corporate Governance Committee. The Board discusses each evaluation to determine what, if any, actions should be taken to improve the effectiveness of the Board or any committee thereof or of the directors.

Attendance of Directors at Board Meetings and Stockholder Meetings

Our Board held eight meetings during the year ended December 31, 2024. During 2024, each person currently serving as a director attended 75% or more of the total number of meetings of the Board and each committee of which he or she was a member. Each director is also encouraged and expected to attend our annual meetings of stockholders.

Committees of the Board of Directors

The Board has established four standing committees: Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee and Research and Development Committee. Each committee operates pursuant to a written charter that has been approved by the Board. A copy of the current charter for each committee is available on our website at www.pyxisoncology.com by selecting the “Investors” link and then the “Corporate Governance” link.

The Audit Committee met five times in 2024, the Compensation Committee met five times in 2024, the Nominating and Corporate Governance Committee met two times in 2024 and the Research & Development Committee met three times in 2024.

Board Membership Criteria and Nomination Process

The Board and the Nominating and Corporate Governance Committee will determine the appropriate characteristics, skills and experience for the board of directors as a whole and for its individual members. The Board and the Nominating and Corporate Governance Committee will consider the minimum general criteria set forth below, and may add any specific additional criteria with respect to specific searches, in selecting candidates and existing directors for service on the Board. An acceptable candidate may not fully satisfy all of the criteria, but is expected to satisfy nearly all of them. Our Board and our Nominating and Corporate Governance Committee believe that candidates for director should have certain minimum qualifications, including being able to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics.

In considering candidates, our Board and Nominating and Corporate Governance Committee intend to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of Pyxis Oncology, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of our stockholders. Our Board and Nominating and Corporate Governance Committee review candidates for director nomination in the context of the current composition of the Board, the operating requirements of Pyxis Oncology and the long-term interests of our stockholders. In conducting this assessment, our Board and Nominating and Corporate Governance Committee may consider background and breadth of experience, age, skills, and such other factors as it deems appropriate given the current needs of the Board and Pyxis Oncology to maintain a balance of knowledge, experience and capability.

In the case of incumbent directors whose terms of office are set to expire, our Board and Nominating and Corporate Governance Committee review such directors’ overall service to Pyxis Oncology during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, our Board and Nominating and Corporate Governance Committee also determine whether the nominee must be independent for purposes of any stock exchange on which Pyxis Oncology’s common stock is listed.

Our Nominating and Corporate Governance Committee will consider director candidates recommended by our stockholders and will apply the same standards in considering director candidates recommended by stockholders as it applies to other candidates. Once the Nominating and Corporate Governance Committee receives a recommendation from a stockholder, it may request additional information from the candidate about the candidate’s independence, qualifications and other information that would assist the committee in evaluating the candidate, as well as certain information that must be disclosed about the candidate in our proxy statement, if nominated. Stockholders may also directly nominate a candidate for director by submitting the candidate's name and relevant information to c/o Corporate Secretary, Pyxis Oncology, Inc., 321 Harrison Avenue, Boston, Massachusetts 02118, pursuant to the advance notice provisions of our bylaws. For more information, please see the section titled “Stockholder Proposals and Nominations.”

Changes in Board of Directors Member Criteria

The Board and Pyxis Oncology wish to maintain a board of directors composed of members who can productively contribute to the success of Pyxis Oncology. From time to time, the Board and/or the Nominating and Corporate Governance Committee may change the criteria for board of director membership to maximize the opportunity to achieve this success. When this occurs, the Board and the Nominating and Corporate Governance Committee will evaluate existing members according to the new criteria. The Board may ask a director who no longer meets the complete criteria for board membership to adjust his or her committee assignments or resign from the Board.

Term Limits and Retirement Age

The Board does not believe it should limit the number of terms for which an individual may serve as a director or set a fixed retirement age. Directors who have served on the Board for an extended period of time are able to provide continuity and valuable insight into Pyxis Oncology, our operations and prospects based on their experience with, and understanding of, our history, policies and objectives. The Board believes that, as an alternative to term limits and retirement policies, it can ensure that the Board continues to evolve and adopt new ideas and viewpoints through the director nomination process described above.

Succession Planning

The Nominating and Corporate Governance Committee develops and periodically reviews with the Chief Executive Officer our plan for succession to the offices of our executive officers and makes recommendations to the Board with respect to the selection of appropriate individuals to succeed to these positions.

Compensation Committee Interlocks and Insider Participation

During the year ended December 31, 2024, none of the members of our Compensation Committee were or had been an officer or employee of us or any of our subsidiaries. In addition, none of our executive officers serves or has served as a member of the board of directors, compensation committee or other board committee performing equivalent functions of any entity that has one or more executive officers serving as one of our directors or on our Compensation Committee.

Corporate Governance Guidelines

The Board has adopted our Corporate Governance Guidelines which provide the framework for our corporate governance along with our amended and restated certificate of incorporation, bylaws, committee charters and other key governance practices and policies.
