PROXY STATEMENT

FOR 2023 ANNUAL MEETING OF SHAREHOLDERS

To be held on Thursday, February 23, 2023

Questions and Answers

about Proxy Materials and Voting

This Proxy Statement, the accompanying Notice of Annual Meeting, proxy card and the Annual Report to Shareholders of Mesa Air Group, Inc. (the “Company,” “Mesa Air Group,” “we, “us” and “our”) are being mailed on or about January 15, 2023. You should read this entire Proxy Statement (this “Proxy Statement”) carefully for information about the proposals to be presented at our 2023 Annual Meeting of Shareholders for the fiscal year ended September 30, 2022 (our “Annual Meeting”). Information contained on, or that can be accessed through, our website is not a part of this Proxy Statement.

The information in the “question and answer” format below is for your convenience only and provides essential information about the proxy materials and how to cast your vote at our Annual Meeting.

What is a proxy?

Our Board of Directors (our “Board”) is asking for your proxy. This means you authorize persons selected by the Company to vote your shares at our Annual Meeting in the way that you instruct. All shares represented by valid proxies that are received and not revoked before our Annual Meeting will be voted at our Annual Meeting in accordance with the shareholder’s specific voting instructions.

Why am I receiving these materials?

You are receiving these materials because at the close of business on January 3, 2023 (the “Record Date”), you owned shares of our common stock, no par value per share. All shareholders of record on the Record Date are entitled to attend and vote at our Annual Meeting.

Each such share of our common stock is entitled to vote at our Annual Meeting. On the Record Date, we had 36,378,550 shares of common stock outstanding. With respect to all of the matters submitted for vote at our Annual Meeting, each share of common stock is entitled to one vote.

What information is contained in this Proxy Statement?

This Proxy Statement includes information about the nominees for directors and other matters to be voted on at our Annual Meeting. It also explains the voting process and requirements; describes the compensation of our principal executive officer, principal financial officer and our other most highly compensated executive officers (collectively referred to as our “named executive officers” or “NEOs”); describes the compensation of our directors; and provides certain other information that the U.S. Securities and Exchange Commission (the “SEC”) rules require.

1

What should I do with these materials?

Please carefully read and consider the information contained in this Proxy Statement and then vote your shares as soon as possible to ensure that your shares will be represented at our Annual Meeting. You may vote your shares prior to our Annual Meeting even if you plan to attend our Annual Meeting in person.

What shares are included on my proxy card?

You will receive one proxy card for all the shares of our common stock that you hold as a shareholder of record (in certificate form or in book-entry form).

If you hold your shares in street name, you will receive voting instructions for each account you have with a broker, bank or other nominee.

What matters am I voting on, how may I vote on each matter and how does our Board recommend that I vote on each matter?

The following table sets forth a description of each of the proposals you are being asked to vote on, how you may vote on each proposal and how our Board recommends that you vote on each proposal:

Proposal	Description	How may I vote?	How does our Board recommend that I vote?
Proposal 1	The election of our seven director nominees, Ellen N. Artist, Mitchell I. Gordon, Dana J. Lockhart, Daniel J. McHugh, Jonathan G. Ornstein, Harvey W. Schiller and Spyridon P. Skiados, each for a one-year term or until his or her successor is duly elected and qualified.	You may (i) vote “FOR” the election of all seven director nominees named herein; (ii) “WITHHOLD” authority to vote for all such director nominees; or (iii) vote “FOR” the election of all such director nominees other than any nominees with respect to whom the vote is specifically “WITHHELD” by indicating in the space provided on the proxy.	Our Board recommends that you vote “FOR” all seven of the director nominees.
Proposal 2	The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023.	You may vote “FOR” or “AGAINST” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023, or you may indicate that you wish to “ABSTAIN” from voting on the matter.	Our Board recommends that you vote “FOR” the ratification of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023.

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

If your shares are registered directly in your name with the Company’s transfer agent, Computershare Inc., you are considered the “shareholder of record” with respect to those shares. The full set of proxy materials has been sent directly to you.

If your shares are held with a broker or in an account at a bank, you are considered the “beneficial owner” with respect to those shares. These shares are sometimes referred to as being held “in street name.” The full set of proxy materials would have been forwarded to you by your broker, bank or other holder of record who is considered the shareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote your shares by using the voting instruction card included in the mailing or by following the instructions on the enclosed proxy card for voting online or by telephone. You will not be able to vote these shares directly unless you obtain a signed legal proxy from your broker, bank or other nominee giving you the right to vote the shares.

How do I vote if I am the shareholder of record?

As a shareholder of record, you may vote your shares in any one of the following ways:

• By Telephone: Call the toll-free number shown on the proxy card;

• On the Internet: Vote on the Internet on the website shown on the proxy card;

• By Mail: Mark, sign, date and return the enclosed proxy card in the postage-paid envelope; or

• In Person: Vote in person at our Annual Meeting.

Whether or not you plan to attend our Annual Meeting, we urge you to vote. Returning the proxy card or voting by telephone or online will not affect your right to attend our Annual Meeting and vote in person.

How do I vote if I am a beneficial owner?

As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares by following the instructions that your broker, bank or other nominee sent to you. You will receive proxy materials and voting instructions for each account that you have with a broker, bank or other nominee. As a beneficial owner, if you wish to change the voting instructions that you have provided your broker, bank or other nominee, you should follow the instructions that your broker, bank or other nominee sent to you.

As a beneficial owner, you are also invited to attend our Annual Meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the meeting unless you obtain a signed legal proxy from your broker, bank or other nominee giving you the right to vote the shares.

What if I am a beneficial owner and do not give voting instructions to my broker?

If you are a beneficial owner of shares, your broker, bank or other nominee is not permitted to vote on your behalf on the election of directors and any other matters to be considered at the Annual Meeting, except for Proposal 2 (the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023), unless you provide specific instructions by completing and returning the voting instruction form or following the instructions provided to you to vote your shares on the Internet or by telephone. If you do not provide voting

3

instructions, your shares will not be voted on any proposal except for Proposal 2. This is called a “broker non-vote”. For your vote to be counted, you will need to communicate your voting decision to your broker, bank or other nominee before the date of the Annual Meeting.

How can I attend our Annual Meeting?

You are entitled to attend our Annual Meeting only if you were a shareholder of record as of the Record Date or you hold a valid proxy for our Annual Meeting as described in the previous question. Because seating is limited, admission to the meeting will be on a first-come, first-served basis. You should be prepared to present photo identification for admittance. If you are not a shareholder of record but hold shares as a beneficial owner, you should provide proof of beneficial ownership as of the Record Date, such as your most recent account statement prior to January 3, 2023, a copy of the voting instruction card provided by your broker, bank or other nominee, or other similar evidence of ownership.

What can I do if I change my mind after I vote?

If you are a shareholder of record, you can revoke your proxy and/or change your vote any time before completion of voting at our Annual Meeting as follows:

• Revoke your proxy: Mail written notice of revocation of your proxy to our Executive Vice President, General Counsel and Secretary at 410 North 44th Street, Suite 700, Phoenix, Arizona 85008;

• Change your vote by Internet or telephone: Vote again over the Internet or by telephone prior to 11:59 p.m., Eastern Time, on February 22, 2023;

• Change your vote by mail: Sign and mail on a timely basis another proxy card with a later date; or

• Change your vote at our Annual Meeting: Attend our Annual Meeting and vote in person by ballot.

If you hold your shares through a bank, broker or other nominee, you can revoke your proxy and/or change your vote as follows:

• Give new voting instructions: Submit new voting instructions in the manner provided by your bank, broker or other nominee; or

• Change your vote at our Annual Meeting: Contact your bank, broker or other nominee to obtain a legal proxy, as described in the answer to the question “How do I vote if I am a beneficial owner?” above, so that you may vote your shares in person at our Annual Meeting.

All shares represented by valid proxies received and not revoked will be voted at our Annual Meeting in accordance with the shareholder’s specific voting instructions.

What if I return my proxy card or vote by Internet or telephone but do not specify how I want to vote?

If you are a shareholder of record and sign and return your proxy card or complete the online or telephone voting procedures, but do not specify how you want to vote your shares, we will vote them as follows:

• “FOR” the election of each of our director nominees, Ellen N. Artist, Mitchell I. Gordon, Dana J. Lockhart, Daniel J. McHugh, Jonathan G. Ornstein, Harvey W. Schiller and Spyridon P. Skiados; and

4

• “FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023.

How many shares must be present or represented to conduct business at our Annual Meeting?

Under our Second Amended and Restated Bylaws, a quorum will exist at our Annual Meeting if shareholders holding a majority of the shares entitled to vote at our Annual Meeting are present in person or by proxy. Shareholders of record who return a proxy or vote in person at our Annual Meeting will be considered part of the quorum. Abstentions and broker non-votes are counted as “present” for determining a quorum.

How are votes counted?

In the election of the seven directors, your vote may be cast “FOR” all of the nominees or your vote may be “WITHHELD” with respect to one or more of the nominees. If you withhold your vote with respect to any nominee, your shares will not be considered to have been voted for or against the nominee. Broker discretionary voting is not allowed for the election of directors.

For all other proposals, your vote may be cast “FOR” or “AGAINST,” or you may “ABSTAIN.” If you “ABSTAIN,” it has the same effect as a vote “AGAINST.” If you sign your proxy card with no further instructions and you are a shareholder of record, then your shares will be voted in accordance with the recommendations of our Board. Broker discretionary voting is allowed for Proposal 2.

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

The following table sets forth the voting requirements with respect to each of the proposals:

Proposal	Description	Voting Requirement
Proposal 1	The election of our seven director nominees, Ellen N. Artist, Mitchell I. Gordon, Dana J. Lockhart, Daniel J. McHugh, Jonathan G. Ornstein, Harvey W. Schiller and Spyridon P. Skiados, each for a one-year term or until his or her successor is duly elected and qualified.	Each director must be elected by a plurality of the votes cast. A plurality means that the nominees with the largest number of votes are elected as directors up to the maximum number of directors to be elected at our Annual Meeting. A “WITHHOLD” vote will have no effect on the vote. If you are a beneficial owner, your broker, bank or other nominee may not vote your shares on this proposal without receiving voting instructions from you.
Proposal 2	The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023.	To be approved, this proposal must be approved by a majority of the votes cast by the shareholders present in person or by proxy and entitled to vote on the proposal, meaning that the votes cast by the shareholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a shareholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” If you are a beneficial

5

Proposal	Description	Voting Requirement
		owner, your broker, bank or other nominee may vote your shares on this proposal without receiving voting instructions from you.

Other matters that may properly come before our Annual Meeting may require more than a majority vote under our Second Amended and Restated Bylaws, our Second Amended and Restated Articles of Incorporation, the laws of Nevada or other applicable laws. We do not know of any such matters as of the date of this Proxy Statement.

Who will count the votes?

Our Executive Vice President, General Counsel and Secretary, Brian S. Gillman, will tabulate the votes and act as the inspector of election.

Where can I find the voting results?

We will announce the preliminary voting results at our Annual Meeting. We will also publish voting results in a Current Report on Form 8-K that we will file with the SEC within four business days of our Annual Meeting. If on the date of such Form 8-K filing the inspector of election for our Annual Meeting has not certified the voting results as final, we will note in the filing that the results are preliminary and publish the final results in a subsequent Form 8-K filing within four business days after the final voting results are known.

Who will pay the costs of soliciting these proxies?

We will bear the entire cost of solicitation of proxies, including preparation, assembly, printing and mailing of this Proxy Statement, the proxy card and any additional information furnished to shareholders. Copies of solicitation materials will be furnished to banks, brokers and other nominees holding shares of voting stock beneficially owned by others to forward to such beneficial owners. We may reimburse banks, brokers and other nominees for their reasonable costs of forwarding proxy materials to beneficial owners. Original solicitation of proxies may be supplemented by electronic means, mail, facsimile, telephone or personal solicitation by our directors, officers or other employees. No additional compensation will be paid to our directors, officers or other employees for such services.

Are you “house holding” for shareholders sharing the same address?

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single proxy statement or annual report, as applicable, addressed to those shareholders. This process, which is commonly referred to as “house holding,” potentially provides extra convenience for shareholders and cost savings for companies.

We have not instituted house holding for shareholders of record. However, certain brokerage firms may have instituted house holding for beneficial owners of shares of our common stock held through brokerage firms. If your household has multiple accounts holding shares of our common stock, you may have already received a house holding notification from your broker. Please contact your broker directly if you have any questions or require additional copies of this Proxy Statement. The broker will arrange for delivery of a separate copy of this Proxy Statement promptly upon your request. Our shareholders may decide at any time to revoke a decision to household, and thereby receive multiple copies.

What is the deadline for shareholders to propose actions for consideration at our annual meeting of shareholders for the fiscal year ending September 30, 2023?

Shareholders who wish to nominate persons for election to our Board or propose other matters to be considered at our annual meeting of shareholders for the fiscal year ending September 30, 2023 must provide us advance notice of the director nomination or shareholder proposal, as well as the information specified in our Second Amended and Restated Bylaws, no earlier than October 27, 2023, and no later than November 26, 2023. Shareholders are advised to review our Second Amended and Restated Bylaws, which contain the requirements for advance notice of director nominations and shareholder proposals. Notice of director nominations and shareholder proposals must be mailed to our Executive Vice President, General Counsel and Secretary at 410 North 44th Street, Suite 700, Phoenix, Arizona 85008. The requirements for advance notice of shareholder proposals under our Second Amended and Restated Bylaws do not apply to proposals properly submitted under Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as those shareholder proposals are governed by Rule 14a-8. We reserve the right to reject, rule out of order or take other appropriate action with respect to any director nomination or shareholder proposal that does not comply with our Second Amended and Restated Bylaws and other applicable requirements.

September 4, 2023 is the deadline for shareholders to submit proposals to be included in our proxy statement under Rule 14a-8 under the Exchange Act. However, if the date of our annual meeting of shareholders for the fiscal year ending September 30, 2023 is changed by more than 30 days from the anniversary of the date of the previous year’s meeting, then the deadline will be a reasonable time before we begin to print and send our proxy statement for our annual meeting of shareholders for the fiscal year ending September 30, 2023. Proposals by shareholders must comply with all requirements of applicable rules of the SEC, including Rule 14a-8, and be mailed to our Executive Vice President, General Counsel and Secretary at 410 North 44th Street, Suite 700, Phoenix, Arizona 85008. We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with Rule 14a-8 and other applicable requirements.

What are the implications of being an “emerging growth company”?

We are an “emerging growth company” under applicable federal securities laws and are therefore permitted to take advantage of certain reduced public company reporting requirements. As an emerging growth company, we provide in this Proxy Statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012, including certain executive compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b-2 under the Exchange Act. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our NEOs or the frequency with which such votes must be conducted. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the completion of our initial public offering (our “IPO”), (ii) the last day of the first fiscal year in which our annual gross revenue is $1.07 billion or more, (iii) the date on which we have, during the previous rolling three-year period, issued more than $1 billion in non-convertible debt securities or (iv) the date on which we are deemed to be a “large accelerated filer” as defined in the Exchange Act.

Who should I call if I have any questions?

Board of Directors

and Corporate Governance

We are strongly committed to good corporate governance practices. These practices provide an important framework within which our Board and management can pursue our strategic objectives for the benefit of our shareholders. Our Board has adopted Amended and Restated Corporate Governance Guidelines (our “Corporate Governance Guidelines”) that set forth the role of our Board, director independence standards, Board structure and functions, director selection considerations and other governance policies. In addition, our Board has adopted written charters for each of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee, as well as the Mesa Air Group, Inc. Code of Conduct and Ethics (our “Code of Conduct”) that applies to all of our employees, officers and directors and all of our subsidiaries. Our Nominating and Corporate Governance Committee reviews our Corporate Governance Guidelines annually and recommends changes to our Board as warranted. Our Corporate Governance Guidelines, our committee charters, and our Code of Conduct, and any waivers or amendments to our Code of Conduct, are all available on our investor relations website (http://investor.mesa-air.com) in the “Corporate Governance – Governance Overview” section.

Director Independence

Our common stock is listed on The Nasdaq Global Select Market (“Nasdaq”). Under the listing requirements and rules of Nasdaq, independent directors must comprise a majority of our Board. In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Under Nasdaq rules, 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. Compensation committee members must not have a relationship with us that is material to the director’s ability to be independent from management in connection with the duties of a compensation committee member. Additionally, audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. To be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee, accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or be an affiliated person of the listed company or any of its subsidiaries.

Our Board has undertaken a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that, other than Jonathan G. Ornstein, our Chairman and Chief Executive Officer, our directors do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of Nasdaq. Accordingly, a majority of our directors are independent, as required under applicable Nasdaq listing rules. In making this determination, our Board considered the current and prior relationships that each non-employee director has with the Company and all other facts and circumstances our Board deemed relevant in determining their independence.

Board Leadership

Although our Board does not have a formal policy as to whether the roles of Chairman of our Board and Chief Executive Officer should be combined or separated, Mr. Ornstein serves as both the

8

Chairman of our Board and our Chief Executive Officer. Our Board believes that the current board leadership structure, coupled with a strong emphasis on board independence, provides effective independent oversight of management while allowing our Board and management to benefit from Mr. Ornstein’s extensive executive leadership and operational experience. On April 9, 2019, the Board established the position of Presiding Independent Director (i.e., Lead Director) and appointed Harvey W. Schiller to serve in that capacity. Mr. Schiller has served on the Company’s Board since 2011, and currently serves as Chair of the Board’s Compensation Committee and a member of the Nominating and Corporate Governance Committee. The Presiding Independent Director is responsible for, among other things, organizing and chairing executive sessions of the independent directors serving on the Company’s Board, acting as a liaison between the Company’s Chairman of the Board and the Board’s independent directors, and carrying out such other responsibilities as defined by the Board.

Executive Sessions of Non-Employee Directors

To encourage and enhance communication among non-employee directors, and as required under applicable Nasdaq rules, our Corporate Governance Guidelines provide that the non-employee directors will meet in executive sessions without management directors or our management on a periodic basis. Accordingly, our Board holds executive sessions at which only those directors who are “independent,” within the meaning of currently applicable Exchange Act rules and the Nasdaq Listing Rules, are present. In accordance with our Corporate Governance Guidelines, the presiding director at the executive sessions is Mr. Schiller, as the Presiding Independent Director.

Communications with our Board of Directors

Shareholders or interested parties who wish to communicate with our Board or with an individual director may do so by mail to our Board or the individual director, care of our Executive Vice President, General Counsel and Secretary at 410 North 44th Street, Suite 700, Phoenix, Arizona 85008. The communication should indicate that it contains a shareholder or interested party communication. In accordance with our Corporate Governance Guidelines, all such communications will be reviewed by our Executive Vice President, General Counsel and Secretary, in consultation with appropriate directors as necessary, and, if appropriate, will be forwarded to the director or directors to whom the communications are addressed or, if none are specified, to the Chairman of our Board.

Committees of our Board of Directors

Our Board has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee which have the composition and responsibilities described below. Our Board may establish other committees to facilitate the management of our business. Copies of the charters of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee are available in the “Corporate Governance – Governance Overview” section of our investor relations website (http://investor.mesa-air.com). Members serve on these committees until their resignation or until otherwise determined by our Board.

Pursuant to our Audit Committee charter, Audit Committee membership shall consist of at least three Board members, all of whom qualify as independent within the meaning of our Corporate Governance Guidelines and satisfy the independence requirements of the Nasdaq Listing Rules and Rule 10A-3(b)(1) under the Exchange Act. Our Audit Committee charter also requires members to have financial literacy and familiarity with fundamental financial statements that would allow them to understand key business and financial controls in the primary industries in which we operate.

Our Board has determined that Ms. Artist and Messrs. Gordon and Lockhart are independent under the Nasdaq Listing Rules and Rule 10A-3(b)(1) under the Exchange Act. In addition, our Board has determined that Ms. Artist is an “audit committee financial expert” within the meaning of SEC regulations. Our Board has also determined that each member of our Audit Committee can read and understand fundamental financial statements in accordance with applicable requirements. In arriving at these determinations, our Board has examined each Audit Committee member’s scope of experience and the nature of his or her employment in the corporate finance sector.

The primary purpose of our Audit Committee is to discharge the responsibilities of our Board with respect to our accounting, financial and other reporting and internal control practices and to oversee our independent registered public accounting firm. Specific responsibilities of our Audit Committee include:

• selecting a qualified firm to serve as our independent registered public accounting firm to audit our financial statements;

• helping to ensure the independence and performance of our independent registered public accounting firm;

• discussing the scope and results of the audit with our independent registered public accounting firm, and reviewing, with management and the independent registered public accounting firm, our interim and year-end operating results;

• reviewing our policies on risk assessment and risk management;

• reviewing related party transactions;

• obtaining and reviewing a report by our independent registered public accounting firm at least annually that describes our internal quality control procedures, any material issues with such procedures and any steps taken to deal with such issues when required by applicable law;

10

• approving (or, as permitted, pre-approving) all audit and all permissible non-audit services, other than de minimis non-audit services, to be performed by our independent registered public accounting firm; and

• oversight of our cyber security risk management programs.

Compensation Committee

Our Compensation Committee currently consists of Messrs. Gordon, McHugh and Schiller, with Mr. Schiller serving as our Compensation Committee Chair. Pursuant to our Compensation Committee charter, our Compensation Committee shall consist of a minimum of three directors, each of whom shall meet Nasdaq’s independence requirements. Our Board has determined that each member of our Compensation Committee is independent under the Nasdaq Listing Rules and is a “non-employee director” as defined in Rule 16b-3 under the Exchange Act.

The primary purpose of our Compensation Committee is to discharge the responsibilities of our Board to oversee our compensation policies, plans and programs, and to review and determine the compensation to be paid to our executive officers, directors and other senior management, as appropriate. Specific responsibilities of our Compensation Committee include:

• reviewing and approving, or recommending that our Board approve, the compensation of our executive officers;

• reviewing and recommending to our Board the compensation of our directors;

• reviewing and approving, or recommending that our Board approve, the terms of compensatory arrangements with our executive officers;

• administering our incentive compensation and other equity plans;

• selecting independent compensation consultants and assessing whether there are any conflicts of interest with any of our Compensation Committee’s compensation advisors;

• reviewing and establishing general policies relating to compensation and benefits of our employees and reviewing our overall compensation philosophy; and

• reviewing our compensation policies and practices as they relate to risk management.

Compensation Committee Interlocks and Insider Participation

None of the members of our Compensation Committee is or has been an executive officer of Mesa Air Group, nor did any of them have any relationships requiring disclosure by us under Item 404 of SEC Regulation S-K. With the exception of Mr. Ornstein, our Chairman and Chief Executive Officer, none of our executive officers served as a director or a member of a compensation committee (or other committee serving an equivalent function) of any other entity, of which an executive officer served as a director of Mesa Air Group or member of our Compensation Committee during the fiscal year ended September 30, 2022.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee currently consists of Ms. Artist and Messrs. Schiller and Skiados, with Mr. Skiados serving as our Nominating and Corporate Governance Committee Chair. Pursuant to our Nominating and Corporate Governance Committee charter, our Nominating and Corporate

11

Governance Committee shall consist of at least three directors, each of whom shall meet Nasdaq’s independence requirements. Our Board has affirmatively determined that each of Ms. Artist and Messrs. Schiller and Skiados meet the definition of “independent director” for purposes of the Nasdaq Listing Rules.

Specific responsibilities of our Nominating and Corporate Governance Committee include:

• identifying, evaluating and selecting, or recommending that our Board approve, nominees for election to our Board;

• considering and making recommendations to our Board regarding the composition of the committees of our Board;

• reviewing developments in our corporate governance practices;

• evaluating the adequacy of our corporate governance practices and reporting;

• reviewing management succession plans;

• developing and making recommendations to our Board regarding our Corporate Governance Guidelines; and

• overseeing an annual evaluation of our Board’s performance and the performance of each committee.

Board and Committee Meetings and Attendance

Our Board is responsible for the oversight of Company management, the strategy of the Company and establishing corporate policies. Our Board and its committees meet throughout the year on a regular schedule, and also hold special meetings and act by written consent from time to time. During the fiscal year ended September 30, 2022, our Board met seven times. Each of the regularly scheduled Board meetings included an executive session of only independent directors. Our Audit Committee met five times during the last fiscal year. Our Compensation Committee met four times during the last fiscal year. Our Nominating and Corporate Governance Committee met four times during the last fiscal year. During the fiscal year ended September 30, 2022, each director attended 75% or more of the aggregate number of Board meetings and meetings of the committees on which he or she served. We traditionally encourage our directors and director nominees to attend our Annual Meetings. Not all of our current directors attended our annual meeting of shareholders in 2022 due to the ongoing worldwide COVID-19 pandemic. While we are currently encouraging our directors or director nominees to attend our 2023 Annual Meeting in person, any material changes in the COVID-19 pandemic (or variants thereof) could impact actual Board member attendance at such meeting.

Risk Oversight

Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and to enhance shareholder value. A fundamental part of risk management is not only understanding the most significant risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for a given company. Our Board, as a whole, determines the appropriate level of risk for us, assesses the specific risks that we face and reviews management’s strategies for adequately mitigating and managing the identified risks. Although our Board administers this risk management oversight function, the committees of our Board support our Board in discharging its oversight duties and addressing risks inherent in their respective areas.

12

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 monitors compliance with legal and regulatory requirements. Our Audit Committee also monitors management’s preparedness for and responses to data security incidents. Our Nominating and Corporate Governance Committee monitors the effectiveness of our Corporate Governance Guidelines. Our Compensation Committee assesses and monitors whether our compensation philosophy and practices have the potential to encourage excessive risk-taking and evaluates compensation policies and practices that could mitigate such risks.

At periodic meetings of our Board and its committees, management reports to and seeks guidance from our Board and its committees with respect to the most significant risks that could affect our business, such as legal, financial, tax and audit-related risks. In addition, among other matters, management provides our Audit Committee periodic reports on our compliance programs and investment policy and practices.

Nominations Process and Director Qualifications

Nomination to our Board of Directors

Candidates for nomination to our Board are selected by our Board based on the recommendations of our Nominating and Corporate Governance Committee in accordance with our Nominating and Corporate Governance Committee charter, our policies, our Second Amended and Restated Articles of Incorporation, our Second Amended and Restated Bylaws, our Corporate Governance Guidelines and the criteria adopted by our Board regarding director candidate qualifications. In recommending candidates for nomination, our Nominating and Corporate Governance Committee considers candidates recommended by directors, officers and employees, as well as candidates that are properly submitted by shareholders in accordance with our policies and our Second Amended and Restated Bylaws, using the same criteria to evaluate all such candidates. Evaluations of candidates generally involve a review of background materials, internal discussions and interviews with selected candidates as appropriate and, in addition, our Nominating and Corporate Governance Committee may engage consultants or third-party search firms to assist in identifying and evaluating potential director nominees.

Additional information regarding the process for properly submitting shareholder nominations for candidates for membership on our Board is set forth above under “Questions and Answers About Proxy Materials and Voting.”

Director Qualifications

With the goal of developing a diverse, experienced and highly qualified board of directors, our Nominating and Corporate Governance Committee is responsible for developing and recommending to our Board the desired qualifications, expertise and characteristics of members of our Board, including qualifications that our Nominating and Corporate Governance Committee believes must be met by a committee-recommended nominee for membership on our Board and specific qualities or skills that our Nominating and Corporate Governance Committee believes are necessary for one or more of the members of our Board to possess.

In addition to the qualifications, qualities, and skills that are necessary to meet U.S. legal and regulatory requirements, Nasdaq’s listing requirements, the provisions of our Second Amended and Restated Articles of Incorporation and our Second Amended and Restated Bylaws, our Corporate Governance Guidelines and each of the charters of our Board committees, our Nominating and

13

Corporate Governance Committee requires the following minimum qualifications to be satisfied by any nominee for a position on our Board:

• personal and professional ethics and integrity;

• proven achievement and competence in the nominee’s field and the ability to exercise sound business judgment;

• skills that are complementary to those of the existing Board members;

• the ability to assist and support management and make significant contributions to our success;

• an understanding of the fiduciary responsibilities that are required of a member of our Board; and

• the commitment of time and energy necessary to diligently carry out these responsibilities.

Our Board and Nominating and Corporate Governance Committee believe that a diversely skilled, experienced and highly qualified board of directors fosters a robust, comprehensive and balanced decision-making process for the continued effective functioning of our Board and success of the Company. Accordingly, through the nomination process, our Nominating and Corporate Governance Committee seeks to promote Board membership that reflects diversity, factoring in gender, race, ethnicity, differences in professional background, education, skill, experience and other individual qualities and attributes that contribute to the total mix of viewpoints and experience. Our Nominating and Corporate Governance Committee evaluates the foregoing factors, among others, and does not assign any particular weighting or priority to any of the factors.

Proposal 1 sets forth a brief biographical description of each nominee’s primary individual experience, qualifications, attributes and skills that led our Board to recommend such nominee to serve as a member of our Board.

PROPOSAL 1:

ELECTION OF DIRECTORS

(Item No. 1 on the Proxy Card)

Composition of our Board of Directors

Our Board currently consists of seven directors. All directors serve a one-year term and are subject to re-election each year.

On the recommendation of our Nominating and Corporate Governance Committee, our Board has nominated the following persons for election as directors at our Annual Meeting:

• Ellen N. Artist

• Mitchell I. Gordon

• Dana J. Lockhart

• Daniel J. McHugh

• Jonathan G. Ornstein

• Harvey W. Schiller

• Spyridon P. Skiados

If elected, each nominee will serve until his or her term expires at our annual meeting of shareholders for the fiscal year ending September 30, 2023 or until his or her successor is duly elected and qualified. See “Director Nominees” below for more information about each nominee.

All of the nominees are currently serving as directors of Mesa Air Group and have consented to being named as nominees. Shareholders voting in person or by proxy at our Annual Meeting may only vote for seven nominees. If, prior to our Annual Meeting, any of the nominees becomes unable to serve as a director, our Board may designate a substitute nominee. In that event, the persons named as proxies intend to vote for the substitute nominee designated by our Board.

Our Board and our Nominating and Corporate Governance Committee believe that each of the above nominees possesses the experience and qualifications that directors of Mesa Air Group should possess, as described in detail below, and that the experience and qualifications of each nominee compliments the experience and qualifications of the other nominees. The experience and qualifications of each nominee, including information regarding the specific experience, qualifications, attributes and skills that led our Board and our Nominating and Corporate Governance Committee to conclude that he or she should serve as a director of Mesa Air Group at the present time, in light of our business and structure, are set forth below.

Vote Required

If a quorum is present, directors are elected by a plurality of the votes of the holders of shares present at the meeting or represented by proxy and entitled to vote on the election of directors. Accordingly, the nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominees named below. If a nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by us.

Our Board recommends a vote “FOR” the election of all seven nominees listed below.

Board Diversity

In August 2021, the SEC approved the Nasdaq’s Board Diversity Rule, which requires all companies listed on Nasdaq’s U.S. exchange to publicly disclose board-level diversity statistics and have, or explain why they do not have, at least two diverse directors. The below Board Diversity Matrix provides the diversity statistics for our Board in the format required by the rule. As disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022, the Company was focused on restructuring its operations with its major partners during fiscal 2022 and did not believe bringing on a new Board member during this process was appropriate.

Board Diversity Matrix (As of August 8, 2022)

Non-Employee Director Compensation

Fees. The following fees were paid to our non-employee directors during the 2022 election year. Directors who are our full-time employees receive no additional compensation for serving as directors. Board members are also reimbursed for all expenses associated with attending Board or committee meetings.

The following table sets forth information concerning the compensation earned by or paid to our non-employee directors during the fiscal year ended September 30, 2022:

Annual retainer (paid quarterly)	$	83,000
Compensation Committee Chair retainer	$	10,000
Nominating and Corporate Governance Chair retainer	$	10,000
Audit Committee Chair retainer	$	15,000
Presiding Independent Director retainer	$	20,000

Equity Awards. Equity awards are made to our non-employee directors on an annual basis. The types and amounts of such awards are set by our Compensation Committee. During the fiscal year ended September 30, 2022, each non-employee director received a restricted common stock award in the aggregate amount of $89,700.

Other benefits. As is common in the airline industry, we provide flight benefits to the members of our Board, whereby each non-employee director and certain family members of directors receive free or reduced-fare travel on flights flown by our major airline partners at no cost to us or the director. We believe that our directors’ use of free air travel is de minimis and we did not maintain any records of non-employee directors’ travel during the fiscal year ended September 30, 2022.

Report of the Audit Committee

The Audit Committee selects and retains an independent registered public accounting firm as the Company’s independent auditor and assists the Board in overseeing (1) the integrity of the Company’s financial statements, (2) the independent auditor’s qualifications and independence, (3) the performance of the Company’s internal audit function and independent auditor, and (4) the compliance by the Company with legal and regulatory requirements related to financial affairs and reporting. The Board of Directors has adopted a written charter for the Audit Committee that addresses the responsibilities of the Audit Committee. This charter is available on our investor relations website (http://investor.mesa-air.com) in the “Corporate Governance – Governance Overview” section.

While the Audit Committee has the responsibilities and powers set forth in its charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company’s financial statements and disclosures are complete and accurate and are in accordance with generally accepted accounting principles and applicable legal and other requirements. These are the responsibilities of management and the independent auditor. Additionally, in performing its oversight function, the Audit Committee necessarily relies on the work and assurances of, and information provided by, management and the independent auditor.

Ernst & Young LLP (“Ernst & Young”) served as the Company’s independent auditor for the fiscal year ended September 30, 2022. In fiscal 2022, the Audit Committee met and held discussions with management and Ernst & Young on numerous occasions. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management and Ernst & Young the Company’s quarterly financial statements prior to the filing of each Quarterly Report on Form 10-Q and the audited financial statements included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2022. The Audit Committee discussed with Ernst & Young matters required to be discussed by the applicable Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee received the written disclosures and the letter from Ernst & Young required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, and the Audit Committee discussed with Ernst & Young the firm’s independence and tenure.

Based upon the Audit Committee’s discussions with management and the independent auditor, and the Audit Committee’s review of the representations of management and the report of the independent auditor to the Audit Committee, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022, as filed with the SEC.

PROPOSAL 2:

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

(Item No. 2 on the Proxy Card)

It is the responsibility of the Audit Committee to select and retain independent auditors. Our Audit Committee has appointed Ernst & Young as our independent auditors for the Company’s fiscal year ending September 30, 2023. Although shareholder ratification of the Audit Committee’s selection of independent auditors is not required by our Second Amended and Restated Bylaws or otherwise, we are submitting the selection of Ernst & Young for shareholder ratification as a matter of good corporate governance and so that our shareholders may participate in this important corporate decision. If not ratified, the Audit Committee will reconsider the selection, although the Audit Committee will not be required to select different independent auditors for the Company. Even if the appointment is ratified, our Board may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of Mesa Air Group and its shareholders.

A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will be available to respond to appropriate questions and, if they desire, to make a statement.

VOTE REQUIRED

An affirmative vote from holders of a majority in voting power of the shares present at the Annual Meeting or represented by proxy and entitled to vote on the proposal is required to ratify the selection of Ernst & Young as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2023. In the event that our stockholders fail to ratify the selection, it will be considered a recommendation to the Board and the Audit Committee to consider other auditors for next year. However, because of the difficulty in making any substitution of auditors after the beginning of the current year, the appointment for 2023 will stand, unless the Audit Committee determines there is a reason to make a change.

POLICY ON AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Consistent with the requirements of the SEC and the PCAOB regarding auditor independence, our Audit Committee has responsibility for appointing, setting compensation, retaining and overseeing the work of our independent registered public accounting firm. In recognition of this responsibility, our Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm to the Company. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of our Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit and case-by-case basis before the independent auditor is engaged to provide each service. All of the services provided by Ernst & Young for the fiscal years ended September 30, 2022 and September 30, 2021 described above were pre-approved by our Audit Committee or our Board. Our Audit Committee determined that the rendering of services other than audit services by Ernst & Young was compatible with maintaining the principal accountant’s independence.

Executive Compensation

Our NEOs, consisting of our principal executive officer and our next four most highly compensated executive officers as of September 30, 2022, were:

• Jonathan G. Ornstein, Chairman and Chief Executive Officer;

• Michael J. Lotz, President and former Chief Financial Officer;

• Brian S. Gillman, Executive Vice President, General Counsel and Secretary;

• Bradford R. Rich, Executive Vice President and Chief Operating Officer; and

• Torque Zubeck, Chief Financial Officer.

Under the SEC’s rules governing proxy disclosure, emerging growth companies like the Company are only required to disclose compensation information for three NEOs (including the CEO). The Company has voluntarily elected to disclose compensation information for Messrs. Rich and Zubeck.

Processes and Procedures for Compensation Decisions

Our Compensation Committee is responsible for the executive compensation programs for our executive officers and reports to our Board on its discussions, decisions and other actions. Our Chief Executive Officer, and from time to time as necessary, in consultation with our Chief Executive Officer and President, makes recommendations to our Compensation Committee regarding short-term and long-term compensation for all of our executive officers (other than himself) based on our results, as well as an individual executive officer’s contribution toward the Company’s results and their performance toward individual goal achievement. Our Compensation Committee then reviews the recommendations and other data and makes decisions as to the total compensation for each executive officer, as well as each individual compensation component.

During 2019, the Compensation Committee engaged Mercer LLC (“Mercer”), an independent executive compensation advisory firm, as the Compensation Committee’s independent compensation advisor. In doing so the Compensation Committee reviewed information regarding the independence and potential conflicts of interest of Mercer. The Compensation Committee members took into account, among other things, the factors enumerated by the SEC and Nasdaq for evaluating compensation advisor independence and concluded that Mercer is independent and that no conflict of interest exists. Representatives of Mercer have direct access to Compensation Committee members without management involvement. The Compensation Committee at any time has sole authority to replace its compensation consultant and/or legal counsel from time to time and hire additional consultant, legal counsel and such other advisors as necessary to assist with the execution of its duties and responsibilities.

As a result of Mercer’s engagement, the Compensation Committee recommended the following changes to non-employee director compensation: (i) a $10,000 increase in annual cash compensation, and (ii) a $15,000 increase in the value of the annual equity grants made to non-employee directors. The Committee also recommended an increase in the annual base salary and annual equity grant for Mr. Gillman, as described elsewhere in this Proxy Statement. No other action was taken with respect to executive compensation in fiscal 2019.

We did not engage Mercer to provide any compensation consulting services in fiscal 2022, fiscal 2021, or fiscal 2020 and no action was taken with respect to executive compensation in such fiscal periods. In addition, under the terms of our Loan and Guarantee Agreement with The United States Department of the Treasury entered into 2021, we are required to comply with certain covenants that restrict changes to the total compensation of certain of our executive officers whose compensation exceeds a specified threshold. As such, we did not engage a compensation consultant for such period.

Michael J. Lotz

We entered into an employment agreement with Mr. Lotz on February 23, 2011, effective as of March 1, 2011, to serve as our President and Chief Financial Officer, which agreement was amended first effective as of January 22, 2014, again effective as of June 1, 2016, and again on July 26, 2018, to consolidate the prior amendments. Mr. Lotz’s employment agreement was further amended effective October 1, 2021 to reflect the voluntary relinquishment of his role as Chief Financial Officer of the Company and to reflect that he will remain involved in the strategic financial direction, strategies, plans and policies of the Company.

Mr. Gillman’s employment agreement entitles him to participate in all employee benefit plans and arrangements available to our executive officers, including the flight benefits discussed above. It also contains certain confidential information covenants prohibiting Mr. Gillman from using or disclosing any of our confidential information, other than as required in the performance of his duties as our Executive Vice President, General Counsel and Secretary, during the term of his employment and for two years thereafter.

Mr. Gillman’s employment agreement also provides him with severance in the event his employment is terminated without Cause (as defined below) by us (or, in certain circumstances, by our successor-in-interest) or if he resigns for Good Reason (as defined below). If Mr. Gillman is terminated without Cause or if he resigns with Good Reason, he is entitled to payment equal to two times the sum of his base salary, plus an amount equal to the greater of (i) his target annual performance bonus or (ii) half the sum of the bonuses (incentive or otherwise) earned by Mr. Gillman with respect to the two fiscal years immediately preceding the year in which his termination occurs. If Mr. Gillman is terminated by us or our successor-in-interest without Cause or he resigns with Good Reason within 12 months following a Change of Control (as defined below), he is entitled to payment equal to three times the sum of his base salary, plus the greater of (i) his maximum target performance bonus for the fiscal year in which the termination occurs or (ii) the amount of all bonuses (incentive or otherwise) paid to Mr. Gillman with respect to the three fiscal years immediately preceding the year in which his termination occurs. Upon Mr. Gillman’s termination without Cause or resignation for Good Reason, he is also entitled to the payment of continued health, dental and vision insurance premiums for himself and any covered dependents for 24 months following termination, and he is entitled to immediate vesting of any unvested equity awards.

For purposes of Mr. Gillman’s employment agreement, “Cause,” “Change of Control” and “Good Reason” have identical meanings to those contained in Mr. Ornstein’s employment agreement, as set forth above.

Under the terms of Mr. Rich’s offer letter, he receives an annual base salary of $300,000 and is eligible to receive an annual performance-based incentive cash bonus of up to $500,000 upon the achievement of established financial and operational goals. Mr. Rich is also eligible to receive an annual equity award under the Company’s 2018 Plan, as determined by our Board or our Compensation Committee, provided such award shall have a grant date value of not less than $200,000 in any fiscal year.

Torque Zubeck

We entered into an employment agreement with Mr. Zubeck, effective March 1, 2021, in connection with his appointment as Senior Vice President of Finance of the Company. Under the terms of his employment agreement, upon his promotion to Chief Financial Officer, which was effective October 1, 2021, Mr. Zubeck (i) receives an annual base salary of $300,000, (ii) is eligible to receive an annual performance-based incentive cash bonus of up to $225,000 upon the achievement of established individual and company operational goals, and (iii) is eligible to receive an annual equity award under the Company’s 2018 Plan, as determined by our Board or our Compensation Committee, provided such award shall have a grant date value of not less than $150,000 in any fiscal year.

Mr. Zubeck is also be entitled (i) to participate in all employee benefit and welfare programs, plans and arrangements (including, without limitation, pension, profit sharing, supplemental pension and other retirement plans, insurance, hospitalization, medical and group disability benefits, travel or accident insurance plans) , and (ii) to receive fringe benefits, such as dues and fees of professional organizations and associations, in each case to the extent that such programs, plans, arrangements, and benefits are from time to time available to the Company’s executive personnel.

Mr. Zubeck’s employment agreement also provides him with severance in the event his employment is terminated without Cause (as defined in the employment agreement) by us or if he resigns for Good Reason (as defined in his employment agreement). If Mr. Zubeck is terminated without Cause or if he resigns with Good Reason, he is entitled to a payment equal to the sum of his then-existing base salary, plus an amount equal to his annual bonus amount which has been earned but has not been paid. If Mr. Zubeck is terminated by us or our successor-in-interest without Cause or he resigns with Good Reason within 12 months following a Change of Control (as defined in the employment agreement), he is entitled to a payment equal to the sum of his then-existing base salary, plus an amount equal to his annual bonus. Upon Mr. Zubeck’s termination without Cause or resignation for Good Reason, he is also entitled to the payment of continued health insurance coverage for himself and any covered dependents for 12 months following termination, subject to certain exceptions, and is entitled to immediate vesting of any unvested equity awards.

Transactions With Related Persons in 2022

Related Party Transaction Policy

Our Board has a written policy and procedures for review and approval of transactions involving the Company and “related persons” (which includes our directors and executive officers or their immediate family members, or shareholders and their immediate family members owning 5% or more of our common stock). The policy applies to any transaction in which the Company is a participant and any related person that has a direct or indirect material interest, excluding transactions: (a) involving payment or reimbursement of expenses of the related person incurred in the ordinary course of the related person’s service as a director or officer of the Company; (b) where the financial or compensatory arrangements are approved or ratified by our Board; (c) where the related person’s interest arises (i) only from such person’s position as a director of a corporation or organization which is a party to the transaction; (ii) only from such person’s direct or indirect ownership of less than a 10% equity interest in another person (other than a partnership, limited liability company, trust or similar entity) that is a party to the transaction; or (iii) from both such position and such ownership; (d) where the related person’s interest arises only from the ownership of a class of equity securities of the Company and all holders of that class receive the same benefits on a pro rata basis; and (e) where an immediate family member’s interest arises from his or her status as an employee of a firm, corporation or other entity for which he or she is not also an officer, director, general partner, or principal.

Our Audit Committee reviews and approves in advance all related person transactions. In determining whether to approve a related person transaction, our Audit Committee looks to whether the related person transaction is on terms and conditions no less favorable to the Company than may reasonably be expected in arm’s-length transactions with unrelated parties. Our Audit Committee will also consider such other factors as it may determine under the circumstances of a particular transaction.

Our Audit Committee is responsible for reviewing the material facts of all related person transactions, subject to the exceptions described above. Our Audit Committee will either approve or disapprove the entry into the related person transaction. If advance approval is not feasible, the transaction will be considered and, if our Audit Committee determines it to be appropriate, ratified at our Audit Committee’s next regularly scheduled meeting. In determining whether to approve or ratify a transaction with a related person, our Audit Committee will take into account, among other factors that it determines to be appropriate, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Information relating to our transactions with related persons is set forth immediately below.

Since the beginning of our fiscal year ended September 30, 2022, we had no transactions pursuant to which we were a participant in which the amount involved exceeded or will exceed $120,000, and in which any of our directors, executive officers or holders of more than 5% of our capital stock, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

Indemnification Agreements

Our Second Amended and Restated Articles of Incorporation compel indemnification of our directors and officers and permit indemnification of our employees and other agents, in each case to the maximum extent permitted by Nevada law, and our Second Amended and Restated Bylaws provide for indemnification of our directors, officers, employees and other agents to the maximum extent permitted by Nevada law. In addition, we have entered into indemnification agreements with our directors and NEOs containing provisions which are in some respects broader than the specific indemnification provisions contained in Nevada law. The indemnification agreements may require us, among other things, to indemnify our directors and officers against certain liabilities that may arise by reason of their status or service as directors and officers and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified.
