Materials and our Annual Meeting."

At the Annual Meeting, you will be asked to do the following:

1. Elect 15 directors to our board of directors to hold office until the 2027 annual

meeting of stockholders or until their respective successors have been elected and

qualified, or until such director's earlier death, resignation, or removal;

2. Approve, on a non-binding advisory basis, the compensation paid to our named

executive officers;

3. Select, on a non-binding advisory basis, whether future advisory votes on the

***Please carefully review the form of proxy that you receive to confirm that it reflects all***

***of your shares of our common stock. If you hold common stock in different accounts, you may***

***need to complete multiple proxy cards to vote all of your shares.***

Whether or not you plan to attend the Annual Meeting via live audio webcast, it is

important that your shares be represented and voted. Please submit your proxy by internet,

telephone, or complete, sign, date and return the enclosed proxy card using the enclosed postage-

historical fact are forward-looking statements. These forward-looking statements, which are

subject to known and unknown risks, uncertainties and assumptions about us, may include

projections of our future financial performance based on our growth strategies and anticipated

trends in our business. These statements are only predictions based on our current expectations

and projections about future events. There are important factors that could cause our actual

results, level of activity, performance or achievements to differ materially from those expressed

or implied by the forward-looking statements. In particular, you should consider the risks and

uncertainties described in Part 1 of our Annual Report on Form 10-K under "Special Note

Regarding Forward-Looking Statements," Item 1A, "Risk Factors", and our other filings with the

SEC. While we believe we have identified material risks, these risks and uncertainties are not

exhaustive. Moreover, we operate in a very competitive and rapidly changing environment. New

risks and uncertainties emerge from time to time, and it is not possible to predict all risks and

uncertainties, nor can we assess the impact of all factors on our business or the extent to which

any factor, or combination of factors, may cause actual results to differ materially from those

contained in any forward-looking statements.

We do not undertake, and expressly disclaim, any duty to update any forward-looking

statement whether as a result of new information, future events or otherwise, except as required

by law. We caution you not to place undue reliance on the forward-looking statements, which

speak only as of the date of this filing.

future advisory votes on the compensation of our named executive officers; and

• "FOR" the ratification of the appointment of KPMG as our independent registered

public accounting firm for the year ending December 31, 2026.

**Who is entitled to vote? How many shares can I vote?**

Holders of our common stock, par value $0.001 per share ("common stock") as of the

close of business on April 20, 2026 (the "Record Date"), may vote at the Annual Meeting. As of

the Record Date, there were 94,800,071 shares of our common stock outstanding. Each

stockholder of our common stock is entitled to one vote for each share of common stock held as

of the Record Date on the matters included in this Annual Meeting. In deciding all matters at the

Annual Meeting, each share of common stock represents one vote.

*Registered Stockholders*. If shares of our common stock are registered directly in your

name with our transfer agent, Computershare Trust Company, N.A., you are considered the

stockholder of record with respect to those shares, and the Notice was provided to you directly

by us. As the stockholder of record, you have the right to grant your voting proxy directly to the

individuals listed on the proxy card or to vote live at the Annual Meeting. Throughout this

section, we refer to registered stockholders as "stockholders of record."

*Street Name Stockholders*. If shares of our common stock are held on your behalf in a

brokerage account or by a bank or other nominee, you are considered to be the beneficial owner

of shares that are held in "street name," and the Notice was forwarded to you by your broker,

bank, or nominee, who is considered the stockholder of record with respect to those shares. As

the beneficial owner, you have the right to direct your broker, bank, or other nominee as to how

to vote your shares. You are also invited to attend the Annual Meeting and vote your shares of

our common stock live by following the instructions provided on your Notice or the instructions

that accompanied your proxy materials. If you request a printed copy of our proxy materials by

mail, your broker, bank, or other nominee will provide a voting instruction form for you to use.

Throughout this section, we refer to stockholders who hold their shares through a broker, bank,

or other nominee as "street name stockholders."

**How many votes are needed for approval of each proposal?**

• Proposal No. 1: The election of directors requires a plurality of the votes cast by

the holders of the shares of our common stock present virtually or represented by

proxy at the Annual Meeting and entitled to vote thereon to be approved.

"Plurality" means that the director nominees who receive the largest number of

votes cast "FOR" such nominees are elected as directors. As a result, any shares

not voted "FOR" a particular director nominee, whether as a result of a withhold

vote or a broker non-vote (described below), will not be counted in such director

nominee's favor and will have no effect on the outcome of the election. You may

vote "FOR," "WITHHOLD," or vote "FOR ALL EXCEPT" one or more of the

director nominees you specify. Broker non-votes will have no effect on the

outcome of this proposal.

• Proposal No. 2: The approval, on a non-binding advisory basis, of the

compensation of our named executive officers requires the affirmative vote of the

holders of a majority of the total number of votes of our common stock present

virtually or represented by proxy at the Annual Meeting and entitled to vote

thereon that voted "FOR" or "AGAINST" this proposal. If the number of votes

cast "FOR" this proposal exceeds the number of votes cast "AGAINST" this

proposal, then the proposal will be deemed approved. You may vote "FOR,"

"AGAINST," or "ABSTAIN" with respect to this proposal. Abstentions (shares

present at the Annual Meeting and marked "ABSTAIN") are counted for purposes

of determining whether a quorum is present and will have the same effect as a

vote "AGAINST" the proposal. Broker non-votes will have no effect on the

outcome of this proposal.

• Proposal No. 3: The non-binding advisory vote on the frequency of future non-

binding advisory votes on the compensation of our named executive officers will

provide stockholders with the opportunity to choose among four options with

respect to this proposal. You may vote for holding the non-binding advisory vote

to approve the compensation of our named executive officers every "ONE

YEAR," "TWO YEARS," "THREE YEARS," or vote for "ABSTAIN." The

frequency receiving the greatest number of votes by our stockholders will be

deemed to be the preferred frequency option of our stockholders. Abstentions and

broker non-votes will have no effect on the outcome of this proposal.

• Proposal No. 4: The ratification of the appointment of KPMG as our independent

registered public accounting firm for the year ending December 31, 2026, requires

the affirmative vote of the holders of a majority of the total number of votes of

our common stock present virtually or represented by proxy at the Annual

Meeting and entitled to vote thereon that voted "FOR" or "AGAINST" this

proposal. If the number of votes cast "FOR" this proposal exceeds the number of

votes cast "AGAINST" this proposal, then it will be deemed approved. You may

vote "FOR," "AGAINST," or "ABSTAIN" with respect to this proposal.

Abstentions are counted for purposes of determining whether a quorum is present

and will have the same effect as a vote "AGAINST" the proposal. Broker non-

votes will have no effect on the outcome of this proposal.

With respect to Proposals 2, 3, and 4, because these proposals are an advisory vote, the

result will not be binding on our Board, our audit committee (the "Audit Committee"), our

compensation committee (the "Compensation Committee"), or the Company. However, our

Board, the Audit Committee, and the Compensation Committee will consider the outcome of the

votes when making future decisions regarding the Company's named executive officer

compensation, the frequency of holding future non-binding advisory votes on the compensation

of our named executive officers, and independent auditor appointment.

**What is a quorum?**

A quorum is the minimum number of shares required to be present at the Annual Meeting

to properly hold an annual meeting of stockholders and conduct business under our amended and

restated by-laws (the "Amended and Restated By-Laws") and Delaware law. The presence,

virtually or by proxy, of the holders of a majority of the common stock issued and outstanding

and entitled to vote at the Annual Meeting will constitute a quorum at the Annual Meeting.

Abstentions, withhold votes, and broker non-votes are counted as shares present and entitled to

vote for purposes of determining a quorum.

**How do I vote?**

If you are a stockholder of record, there are four ways to vote:

• by internet at www.proxyvote.com, 24 hours a day, seven days a week, until

11:59 p.m. Eastern Time on June 15, 2026 (please have your Notice or proxy card

in hand when you visit the website);

• by toll-free telephone at 1-800-690-6903, until 11:59 p.m. Eastern Time on June

15, 2026 (please follow the instructions on your proxy card or voting instruction

form from your broker provided to you by email or over the internet);

• by completing and mailing your proxy card (if you received printed proxy

materials) which must be received prior to the Annual Meeting; or

• by attending the Annual Meeting by visiting

www.virtualshareholdermeeting.com/MIAX2026, where you may vote and

submit questions during the meeting. Please have your Notice, proxy card or the

instructions that accompanied your proxy materials in hand when you visit the

website.

Even if you plan to attend the Annual Meeting, we recommend that you also vote by

proxy so that your vote will be counted if you later decide not to attend the Annual Meeting.

If you are a street name stockholder, you will receive voting instructions from your

broker, bank, or other nominee. You must follow the voting instructions provided by your

broker, bank, or other nominee in order to direct your broker, bank, or other nominee on how to

vote your shares. Street name stockholders should generally be able to vote by returning a voting

instruction form and may be able to vote by telephone or on the internet, depending on the voting

process of your broker, bank, or other nominee. As discussed above, if you are a street name

stockholder, you may not vote your shares live at the virtual Annual Meeting unless you obtain a

legal proxy from your broker, bank, or other nominee.

**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

any time before the Annual Meeting by:

• entering a new vote by internet or by telephone;

• completing and returning a later-dated proxy card; or

• attending and voting at the Annual Meeting (although attendance at the Annual

Meeting will not, by itself, revoke a proxy).

If you are a street name stockholder, your broker, bank, or other nominee can provide you

with instructions on how to change or revoke your vote.

**What do I need to do to attend and participate in the Annual Meeting?**

The Annual Meeting will be a completely virtual meeting of stockholders, which we

believe enables participation from more of our stockholders. Stockholders of record and street

name stockholders with a legal proxy from their broker, bank or other nominee will be able to

attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/MIAX2026, which

will allow such stockholders to submit questions during the meeting and vote shares

electronically at the meeting.

We designed the format of the virtual Annual Meeting to ensure that our stockholders are

afforded the same rights and opportunities to participate as they would at an in-person meeting

and to enhance stockholder access, participation, and communication through online tools. The

virtual format facilitates stockholder attendance and participation by enabling stockholders to

participate fully and equally from any location around the world.

During the meeting, you will have the ability to submit questions real-time via the virtual

meeting website, with a limit of one question per stockholder. We will answer questions

submitted in accordance with the meeting rules of conduct in the time allotted for the meeting.

Only questions pertaining to the proposals to be acted on at the Annual Meeting will be answered

and we reserve the right to exclude questions that are, among other things, irrelevant to meeting

matters, irrelevant to our business, related to material non-public information of the Company,

related to personal matters or grievances, derogatory or in bad taste, related to pending or

threatened litigation, or that are otherwise inappropriate (as determined by the chair of the

Annual Meeting or our corporate secretary ("Corporate Secretary")). Questions should be

succinct and cover only one topic. Questions that are substantially similar may be grouped and

answered together to avoid repetition.

To participate in the Annual Meeting, you will need the 16-digit control number included

on your Notice, proxy card or the instructions that accompanied your proxy materials to attend

the Annual Meeting. The Annual Meeting webcast will begin promptly at 8:00 a.m. Eastern

Time. We encourage you to access the meeting prior to the start time. Online check-in will begin

at 7:45 a.m. Eastern Time, and you should allow ample time for the check-in procedures.

**What if during the check-in time or during the meeting I have technical difficulties or** 

**trouble accessing the virtual meeting website?**

We will have technicians to assist you if you experience technical difficulties accessing

the virtual meeting. If you encounter any difficulties while accessing the virtual meeting during

the check-in or meeting time, a technical assistance phone number will be made available on the

virtual meeting registration page 15 minutes prior to the start of the meeting.

**What is the effect of giving a proxy?**

Proxies are solicited by and on behalf of our Board. Thomas P. Gallagher and Barbara J.

Comly have been designated as proxy holders by our Board. When proxies are properly dated,

executed, and returned, the shares represented by such proxies will be voted at the Annual

Meeting in accordance with the instructions of the stockholder. If no specific instructions are

given, however, the shares will be voted in accordance with the recommendations of our Board

as described above. If any matters not described in this Proxy Statement are properly presented at

the Annual Meeting pursuant to our Amended and Restated By-Laws, the proxy holders will use

their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned or

postponed, the proxy holders can vote the shares on the new Annual Meeting date as well, unless

you have properly revoked your proxy instructions, as described above.

**Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of** 

**proxy materials?**

In accordance with the rules of the SEC, we have elected to furnish our proxy materials,

including this Proxy Statement and our Annual Report on Form 10-K, primarily via the internet.

The Notice containing instructions on how to access our proxy materials is first being mailed on

or about April 27, 2026 to all stockholders entitled to vote at the Annual Meeting. All

stockholders will have the ability to access the proxy materials on the website referred to in the

Notice (www.proxyvote.com). Stockholders may also request to receive proxy materials for this

Annual Meeting or future meetings of stockholders in printed form by mail or electronically by

e-mail by following the instructions contained in the Notice. We encourage stockholders to take

advantage of the availability of our proxy materials on the internet to help reduce the

environmental impact and cost of the Annual Meeting.

**What does it mean if I receive more than one Notice, proxy card or voting instruction** 

**form?**

It generally means that some of your shares are registered differently or are in more than

one account. Please provide voting instructions for all Notices, proxy cards and voting

instruction forms you receive.

**How are proxies solicited for the Annual Meeting?**

Our directors and employees are soliciting proxies for the Annual Meeting. All expenses

associated with this solicitation will be borne by us. We will reimburse brokers or other

nominees for reasonable expenses that they incur in sending our proxy materials to you if a

broker, bank, or other nominee holds shares of our common stock on your behalf. In addition,

our directors and employees may also solicit proxies in person, by telephone or by other means

of communication. Our directors and employees will not be paid any additional compensation for

soliciting proxies.

**How may my brokerage firm or other intermediary vote my shares if I fail to provide** 

**timely directions?**

Brokerage firms and other intermediaries holding shares of our common stock in street

name for beneficial owners are generally required to vote such shares in the manner directed by

such beneficial owners. In the absence of timely directions, your broker will have discretion to

vote your shares on our sole "routine" matter: the proposal to ratify the appointment of KPMG as

our independent registered public accounting firm for the year ending December 31, 2026. Your

broker will not have discretion to vote on any other proposals, which are "non-routine" matters,

absent direction from you. We refer to the absence of a vote, including on a non-routine

proposal, where the broker has not received instructions as a "broker non-vote." Broker non-

votes occur when shares held by a broker for a beneficial owner are not voted because the broker

did not receive voting instructions from the beneficial owner and lacked discretionary authority

to vote the shares. Broker non-votes are counted for purposes of determining whether a quorum

is present and have no effect on the outcome of the matters voted upon. Accordingly, we

encourage you to provide voting instructions to your broker, whether or not you plan to attend

the Annual Meeting.

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

We will announce preliminary voting results at the Annual Meeting. We will also

disclose voting results on a current report on Form 8-K that we will file with the SEC within four

business days after the Annual Meeting. If final voting results are not available to us in time to

file a current report on Form 8-K within four business days after the Annual Meeting, we will

file a current report on Form 8-K to publish preliminary results and will provide the final results

in an amendment to the current report on Form 8-K as soon as they become available.

**I share an address with another stockholder, and we received only one paper copy of the** 

**Notice or proxy materials. How may I obtain an additional copy?**

We have adopted a procedure approved by the SEC called "householding" which will

reduce our printing costs and postage fees. Under this procedure, multiple stockholders residing

at the same address will receive a single copy of the Notice or, as applicable, proxy materials

unless the stockholder notified us that they wish to receive multiple copies of such materials.

Stockholders may revoke their consent to householding at any time by contacting Broadridge

Financial Services, Inc. ("Broadridge") either by calling toll-free at 1-800-690-6903, or by

writing to Broadridge Financial Solutions, Householding Department, 51 Mercedes Way,

Edgewood, NY 11717. We will remove you from the householding program within 30 days of

receipt of your request, following which you will receive multiple copies of such materials.

If you are a stockholder of record, upon written or oral request, we will promptly deliver

a separate copy of the Notice or proxy materials to such stockholder at a shared address to which

we delivered a single copy of any of these materials. To receive a separate copy of the Notice or

proxy materials, such stockholder may contact Broadridge by:

• Internet: www.proxyvote.com

• Telephone: 1-800-690-6903

Additionally, stockholders of record who share the same address and receive multiple

copies of the Notice or proxy materials can request a single copy of such materials by contacting

Broadridge at the address or telephone number above.

Street name stockholders may contact their broker, bank, or other nominee to request

information about householding.

**PROPOSAL NO. 1:**

**ELECTION OF DIRECTORS**

Our Board currently consists of 15 directors. Pursuant to the terms of our amended and

restated certificate of incorporation (the "Amended and Restated Certificate of Incorporation"),

all directors will be elected for annual terms following the expiration of their initial term. For

more information on the structure of our Board, see the section titled "Board of Directors and

Corporate Governance."

**Nominees for Director**

At the recommendation of our nominating and corporate governance committee (the

"Nominating and Corporate Governance Committee"), our Board proposes that each of the

following director nominees be re-elected or elected, as applicable, at the Annual Meeting with

each to serve for a one-year term expiring at our 2027 Annual Meeting and until such director's

successor is duly elected and qualified or until such director's earlier death, resignation,

disqualification, or removal:

| Lisa Moore |
| Mark F. Raymond |
| Cynthia Schwarzkopf |
| Eric Sites |
| Jill E. Sommers |
| Paul V. Stahlin |
| J. Gray Teekell |

---

Each of the director nominees is a current director of the Company other than

Abdulwahab Ahmad Al-Nakib. For more information concerning the director nominees, see the

section titled "Director Nominees" below.

If any director nominee for any reason is unable to serve or for good cause will not serve,

the proxies may be voted for such substitute director nominee as the proxy holder might

determine. Each director nominee has consented to being named in the Proxy Statement and to

serve if elected. Proxies cannot be voted for a greater number of individuals than the 15 director

nominees named. Stockholders may not cumulate votes for the election of directors.

**Vote Required**

The election of directors requires a plurality of the votes cast by the holders of the shares

of our common stock present virtually or represented by proxy at the Annual Meeting and

entitled to vote thereon which means that a director will be elected if the number of votes cast

"FOR" the director exceeds the number of votes cast "AGAINST" the director. Broker non-votes

and withhold will have no effect on the outcome of this proposal.

**Our Board recommends that you vote "FOR" all director nominees in the election of the 15** 

**director nominees.**

**Board Composition**

Our Amended and Restated By-Laws provides that our Board will consist of not less than

3 and not more than 31 directors. Our Board currently has 15 directors. Each director is elected

annually to serve until the next annual meeting of stockholders and until such director's

successor is duly elected or qualified, except in the event of such director's earlier death,

resignation or removal. There is no limit on the number of terms a director may serve on our

Board.

**General**

At the Annual Meeting, our stockholders will be asked to re-elect 14 director nominees

and elect 1 director nominee as set forth below, each to serve until the 2027 Annual Meeting. All

of the director nominees have been recommended for election by our Nominating and Corporate

Governance Committee and approved and nominated for election by our Board.

All of the director nominees have indicated their willingness to serve if elected. If any

director nominee is unable or unwilling to serve as a director at the time of the Annual Meeting,

then shares represented by properly executed proxies will be voted at the discretion of the

persons named in those proxies for such other person as the Board may designate. We do not

presently expect that any of the director nominees will be unavailable. Your proxy for the

Annual Meeting cannot be voted for more than 15 director nominees.

**Qualifications and Experience**

The Board believes that the skills, qualifications and experiences of the director nominees

make them all highly qualified to serve on our Board, both individually and as providing

complementary skills on our Board. As outlined in our principles of corporate governance (the

"Principles of Corporate Governance"), when evaluating director nominees, the Nominating and

Corporate Governance Committee considers various attributes of such director nominee,

including integrity, background, viewpoint, and experience, financial skills, breadth of

experience, knowledge about our business and industry, and ability to devote adequate time and

effort to responsibilities of our Board. Additional criteria for serving as a director may be

established by the Nominating and Corporate Governance Committee from time to time.

**Director Nominees**

Set forth below is the biographical information, as of the date of this Proxy Statement, for

each of the directors nominated to serve on our Board for a one-year term until the 2027 Annual

Meeting, as well as the reasons why the Board believes each candidate is well suited to serve as a

director. The terms indicated for service include the service on our Board prior to our initial

public offering ("IPO"), as applicable.

**BOARD OF DIRECTORS AND CORPORATE GOVERNANCE**

**Director Independence**

Under the rules of the New York Stock Exchange ("NYSE"), independent directors must

comprise a majority of a listed company's board of directors within one year of the completion

of its initial public offering. In addition, the rules of NYSE require that, subject to specified

exceptions, each member of a listed company's audit and compensation committees be

independent and that director nominees be selected or recommended for the board's selection by

independent directors constituting a majority of the independent directors or by a nominating and

corporate governance committee comprised solely of independent directors. Under the rules of

NYSE, a director will only qualify as "independent" 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 and that such person is

"independent" as defined under NYSE rules and the Securities Exchange Act of 1934, as

amended (the "Exchange Act") rules.

Audit committee members must also satisfy the independence criteria set forth in Rule

10A-3 under the Exchange Act. In order 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 their capacity

as a member of the audit committee, the board of directors, or any other board committee: (1)

accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed

company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of

its subsidiaries.

Based upon information requested from and provided by each director concerning their

background, employment and affiliations, including family relationships, our Board has

determined that each of our current directors, with the exception of Thomas P. Gallagher, John

Beckelman, Lee Becker, Kurt M. Eckert and Eric Sites, is an "independent director" as defined

under applicable rules of NYSE, including, in the case of David Brown, Lisa Moore and Paul V.

Stahlin, the independence criteria set forth in Rule 10A-3 under the Exchange Act. Each of the

members of our Compensation Committee are also "non-employee directors" as defined in

Section 16b-3 of the Exchange Act. In making such determination, our Board considered the

relationships that each such non-employee director has with us and all other facts and

circumstances that our Board deemed relevant in determining their independence, including the

beneficial ownership of our common stock by each non-employee director.

**Leadership Structure of the Board**

The Nominating and Corporate Governance Committee and the Board annually review

the Board's leadership structure to evaluate whether the structure remains appropriate for us. Our

Principles of Corporate Governance provide our Board with flexibility to combine or separate the

positions of chair of our Board and Chief Executive Officer. Our Chief Executive Officer

currently serves as the chair of the Board. Our Board and Nominating and Corporate Governance

Committee have concluded that our current leadership structure is appropriate at this time and

that it is in the best interests for us and our stockholders for Thomas P. Gallagher to serve as both

Chairman and Chief Executive Officer due to his in-depth knowledge of exchange markets, his

experience and guidance as a founder of the Company, and his successful execution of key

strategic initiatives to grow the Company.

***Board Risk Oversight Process***

Our Board plays an active role, as a whole and also at the committee level, in overseeing

the management of our business risks. Our Board, as a whole, is responsible for general

oversight of business risks and regular review of information regarding our risks, including

financial and operational risks. Our risk committee (the "Risk Committee", together with the

Audit Committee, the Compensation Committee and the Nominating and Corporate Governance

Committee, the "Committees") is responsible for overseeing the risk assessment and risk

management of our Company and subsidiaries, including risks related to our compliance with

laws, regulations and our policies and risks related to cybersecurity. Our Audit Committee is

responsible for overseeing the Company's risk assessment and risk management with respect to

financial reporting. The Audit Committee reviews and discusses with management, and makes

recommendations to the Board, as appropriate, regarding our financial reporting risks and the

steps and mitigating activities used by the Company to monitor and control such risks, including

guidelines and policies to govern the process by which this is handled. Our Compensation

Committee oversees the assessment of risks related to our compensation policies and programs

applicable to officers and employees. Our Board receives regular reports and input from each of

the Committees with respect to their particular risk oversight responsibilities.

***Board Oversight of Corporate Strategy***

Our Board actively oversees management's establishment and execution of corporate

strategy, including reviewing and approving our strategies and long-term plans, annual operating

and capital budgets and significant transactions, as well as overseeing our processes for assessing

and managing risk. The Board reviews our strategic plan at least annually and monitors its

implementation throughout the year. Our Board's skill set and experience enhances their ability

to support management in the execution and evaluation of our corporate strategy.

***Management Succession Planning***

In connection with its oversight of our management, one of our Board's core

responsibilities is to engage in succession planning for our Board and key leadership roles on our

Board and its Committees, including to plan for the succession of our Chief Executive Officer.

Our Board has delegated primary oversight responsibility for succession planning for our key

leadership positions, including our Chief Executive Officer, to the Nominating and Corporate

Governance Committee. The charter of the Nominating and Corporate Governance Committee

provides that the Nominating and Corporate Governance Committee will at least annually review

Board succession planning and management development, including recommendations and

evaluations of potential successors to fill the Chief Executive Officer position and other senior

management positions. The succession planning process includes consideration of both ordinary

course succession, in the event of planned promotions and retirements, and planning for

situations where the Chief Executive Officer or another member of senior management

unexpectedly becomes unable to perform the duties of their positions.

***Board Oversight of Information Security***

The Board recognizes that our business depends on the confidentiality, integrity,

availability, performance, security, and reliability of our data and technology systems and

devotes time and attention to the oversight of cybersecurity and information security risk.

The Risk Committee reviews reports regarding technology operations, technology

governance, information security, and business continuity planning ("BCP") for the Company

and our operating subsidiaries. Written reports from our Chief Information Security Officer

address the results of the risk assessment process, risk management and control decisions, any

material service provider arrangements, any significant outages, results of physical and

cybersecurity monitoring and testing, BCP exercise schedules and results, BCP invocations,

physical or cybersecurity breaches or violations and management's response, significant data

privacy matters, and any recommendations for major changes to such programs. The Risk

Committee reports findings and recommendations to the Board as needed.

For more information on our cybersecurity risk management systems and processes, see

the section titled "Part I–Item 1C. Cybersecurity" in our Annual Report on Form 10-K.

**Board Attendance**

***Board of Directors and Committee Meetings and Attendance***

We became a public company upon the completion of our IPO in August 2025. In

connection with the IPO, we authorized the formation of a Nominating and Corporate

Governance Committee, and restructured our other committees to operate as public company

committees. During 2025, our Board met nine (9) times, the Audit Committee met five (5) times,

the Compensation Committee met four (4) times, the Nominating and Corporate Governance

Committee met three (3) times and the Risk Committee met three (3) times.

During 2025, each member of our Board attended at least 75% of the aggregate of (i) the

total number of meetings of our Board held during the period for which he or she was a director

and (ii) the total number of meetings held by all committees of our Board on which he or she

served during the periods that he or she served.

***Executive Sessions***

To encourage and enhance communication among non-employee directors, and as

required under applicable NYSE rules, our Corporate Governance Guidelines provide that the

non-employee directors will meet in executive sessions without management present on a

periodic basis and without non-independent directors no less than once per year. Such executive

sessions generally will be led by our lead director.

***Annual Meeting Attendance***

We encourage members of the Board to attend our Annual Meeting. This is our first

Annual Meeting since our IPO; therefore, we did not have an annual meeting last year for our

Board to attend. Meetings of the Board and the Committees are being held in conjunction with

the Annual Meeting. We expect all director nominees will attend the Annual Meeting.

**Committees of the Board**

***Overview***

Our Board has the following standing committees:

• Nominating and Corporate Governance Committee,

• Audit Committee,

• Compensation Committee, and

• Risk Committee.

Each of the Committees has a charter available on the "Governance" page of our investor

guidelines cover a number of areas, including oversight responsibilities, committee structures,

director qualifications, meeting procedures, risk management, succession planning, director

compensation, compliance, confidentiality, performance evaluations (including self-evaluations

effective governance and compliance with legal and regulatory requirements. A copy of our

Principles of Corporate Governance is available on the Governance section of our investor

relations website, www.ir.miaxglobal.com. The information on our website is not intended to

form a part of or be incorporated by reference into this Proxy Statement.

***Code of Business Conduct and Code of Ethics***

We have adopted a written code of business conduct ("Code of Conduct") that applies to

our directors, officers and employees. We have also adopted a code of ethics for senior financial

officers ("Code of Ethics"). Current copies of the Code of Conduct and Code of Ethics are

We expect that any amendments to the Code of Conduct or Code of Ethics, as well as any

waivers under the Code of Ethics, will be disclosed on our website. The information on our

website is not intended to form a part of or be incorporated by reference into this Proxy

Statement.

***Compensation Committee Interlocks and Insider Participation***

None of the current members of our Compensation Committee, or any member that

served during the past fiscal year, is or has been at any time an officer or employee of our

Company. None of our executive officers currently serves, or in the past fiscal year has served,

performing equivalent functions) of any entity that has one or more of its executive officers

serving on our Compensation Committee or our Board. See the section titled "Certain

Relationships and Related Party Transactions" for information about related party transactions

involving members of our Board and Compensation Committee.

***Insider Trading Policy***

Our insider trading policy (the "Insider Trading Policy") prohibits Company directors,

officers and employees worldwide from trading in Company securities while in possession of

material, non-public information about the Company. The Insider Trading Policy is designed to

promote compliance with insider trading laws, rules and regulations, as well as the rules and

regulations of the NYSE. The policy also applies to transactions in the securities of other entities

to the extent covered persons are in possession of any material, non-public information relating

to those securities gained in the course of a covered person's relationship with the Company.

Under the policy, certain individuals are prohibited from trading in our securities during various

times throughout the year known as "blackout periods," and those individuals must also receive

pre-clearance from our General Counsel or a designee thereof in our legal department before

buying, selling, transferring or otherwise trading in our securities.

Our Insider Trading Policy prohibits all covered persons (as such term is defined therein)

from entering into transactions involving options to purchase or sell our common stock or other

derivatives related to our common stock, except for employee stock options and other securities

issued pursuant to Company equity incentive plans.

All covered persons are prohibited from entering into pledges or margin loans of our

securities, other than if a covered person wishes to pledge securities as collateral for a loan and

clearly demonstrates the financial capacity to repay such loan without resort to the pledged

securities, provided that they otherwise comply with the remainder of our Insider Trading Policy.

Any of our Company directors, executive officers or other corporate officers who wishes to

pledge our securities as collateral for a loan must receive approval from our Compensation

Committee prior to such transaction.

Our Insider Trading Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K.

*Rule 10b5-1 Trading Plans*

As an exception to the trading restrictions that otherwise apply under our Insider Trading

Policy, covered persons may complete pre-scheduled or pre-arranged transactions in our

securities at any time, including during blackout periods or even when the covered person

possesses material non-public information under properly established Rule 10b5-1 plans adopted

pursuant to Rule 10b5-1 of the Exchange Act. Under Rule 10b5-1, insiders can buy and sell our

stock over a designated period by adopting pre-arranged stock trading plans at a time when they

are not aware of material non-public information about us, and thereafter trade shares of our

common stock in accordance with the terms of their predetermined stock trading plans without

regard to whether or not they are in possession of material non-public information about us at the

time of the sale. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters

established by an individual when entering into the plan, without further direction from the

individual while the plan is in effect.

Under our Insider Trading Policy, covered persons who desire to implement or modify a

Rule 10b5-1 plan must first submit and obtain approval by the General Counsel or a designee

thereof in our legal department of the specific plan proposed. In order to be eligible for approval,

any adoption or modification of a Rule 10b5-1 plan must occur outside of a blackout period

when the covered person is not aware of material, non-public information about our Company or

our securities, among other conditions, and transactions conducted under such plans are subject

to certain "cooling-off" periods.

***Compensation Recovery Policy***

We have adopted a compensation recovery policy (the "Clawback Policy") intended to

comply with applicable SEC rules, Section 10D of the Exchange Act, Rule 10D-1 of the

Exchange Act and Section 303A.14 of the NYSE Listed Issuer Manual. The Clawback Policy is

administered by our Compensation Committee (in such capacity, the "Administrator") and

enables us to recover from current and former executive officers (as such term is defined in the

Clawback Policy), and such additional employees as may be identified by the Administrator

from time to time, excess incentive compensation (as defined in the Clawback Policy) in the

event of an accounting restatement resulting from material noncompliance with any financial

reporting requirements under federal securities laws.

A copy of our Clawback Policy is filed as Exhibit 97.1 to our Annual Report on Form 10-

K. **Communications by Stockholders and Other Interested Parties with the Board**

Stockholders and other interested parties may contact an individual director, the Board as

a group, or a specified Board committee or group, including the independent directors as a group,

by sending regular mail to: Miami International Holdings, Inc., Attn: Corporate Secretary, 7

Roszel Road, Suite 1A, Princeton, New Jersey, 08540.

Each communication should specify which director or directors the communication is

addressed to, as well as the general topic of the communication. The Company will receive the

communications and process them before forwarding them to the addressees. The Company may

also refer communications to other departments within the Company. The Company generally

will not forward to the directors a communication that is primarily commercial in nature, relates

to an improper or irrelevant topic, or requests general information regarding the Company.

**PROPOSAL NO. 2:**

**APPROVE, ON A NON-BINDING ADVISORY BASIS, THE COMPENSATION OF OUR** 

**NAMED EXECUTIVE OFFICERS**

In accordance with Section 14A of the Exchange Act and the rules of the SEC, we are

providing stockholders with an opportunity to make a non-binding, advisory vote on the

compensation of our named executive officers. This non-binding advisory vote is commonly

referred to as a "Say-on-Pay" vote and gives our stockholders the opportunity to express their

views on our named executive officers' compensation as a whole. This vote is not intended to

address any specific item of compensation or any specific named executive officer, but rather the

overall compensation of all of our named executive officers and the philosophy, policies, and

practices described in this Proxy Statement.

Stockholders are urged to read the section titled "Compensation Discussion and

Analysis," which discusses how our executive compensation policies and procedures implement

our compensation philosophy and contains tabular information and narrative discussion about the

compensation of our named executive officers. Our Compensation Committee and Board believe

that these policies and procedures are effective in implementing our compensation philosophy

and in achieving our goals. We routinely review our compensation practices and engage in

ongoing dialogue with our stockholders to ensure our practices are aligned with stockholder

interests and reflect best practices. Accordingly, we ask our stockholders to vote "FOR" the

following resolution at the Annual Meeting:

"***RESOLVED****, that the Company's stockholders approve, on a non-binding advisory* 

*basis, the compensation of the named executive officers, as disclosed in the Proxy* 

*Statement pursuant to Item 402 of Regulation S-K, including as disclosed in the section* 

*titled "Compensation Discussion and Analysis," the compensation tables and narrative* 

*discussion and the other related disclosures*."

As an advisory vote, this proposal is not binding. However, our Board and Compensation

Committee, which is responsible for designing and administering our executive compensation

program, value the opinions expressed by stockholders in their vote on this proposal and will

consider the outcome of the vote when making future compensation decisions for our named

executive officers.

**Vote Required**

The approval, on an advisory non-binding basis, of the compensation of our named

executive officers requires the affirmative vote of the holders of a majority of the total number of

votes of our common stock present virtually or represented by proxy at the Annual Meeting and

entitled to vote thereon that are voted "FOR" or "AGAINST" the proposal. Stockholders may

also abstain from voting. Abstentions will have the same effect as a vote "AGAINST" the

proposal. Broker non-votes will have no effect on the outcome of this proposal.

**Our Board recommends that you vote "FOR" the approval, on a non-binding advisory** 

**basis, of the compensation of our named executive officers.**

**PROPOSAL NO. 3:**

**APPROVE, ON A NON-BINDING ADVISORY BASIS, THE FREQUENCY OF FUTURE** 

**ADVISORY VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE** 

**OFFICERS**

In accordance with Section 14A of the Exchange Act and SEC rules, we are providing

our stockholders with an opportunity to make a non-binding, advisory vote on the frequency of

future non-binding advisory votes on the compensation of our named executive officers. This

non-binding advisory vote is commonly referred to as a "Say-on-Frequency" vote and must be

submitted to stockholders at least once every six years.

You have four choices for voting on this proposal. You can choose whether future non-

binding advisory votes on the compensation of our named executive officers should be

conducted every "ONE YEAR," "TWO YEARS," or "THREE YEARS." You may also

"ABSTAIN" from voting.

After careful consideration, our Board recommends that future non-binding advisory

votes on the compensation of our named executive officers be held every three years. Our Board

believes that holding a vote every three years is the most appropriate option because (i) it will

enable stockholders to provide the Company with input regarding the compensation of the named

executive officers on a more informed and thoughtful manner based on a long-term analysis of

the Company's compensation program; and (ii) it avoids placing too much emphasis on the

results or actions of a single year and will instead allow stockholders to make a more meaningful

evaluation of the Company's performance compared to the Company's compensation practices.

Stockholders are not voting to approve or disapprove the Board's recommendation.

Instead, stockholders may indicate their preference regarding the frequency of future non-

binding advisory votes on the compensation of our named executive officers by selecting one

year, two years, or three years. Stockholders that do not have a preference regarding the

frequency of future advisory votes may abstain from voting on the proposal.

As an advisory vote, this proposal is not binding. However, our Board and Compensation

Committee value the opinions expressed by stockholders in their vote on this proposal and will

consider the outcome of the vote when making future decisions regarding the frequency of

holding future non-binding advisory votes on the compensation of our named executive officers.

Because this is an advisory vote and therefore not binding on our Board or our Company, our

Board may decide that it is in the best interests of our stockholders that we hold an advisory vote

on the compensation of our named executive officers more or less frequently than the option

preferred by our stockholders. The results of the vote will not be construed to create or imply any

change or addition to the fiduciary duties of our Board.

**Vote Required**

This vote is advisory only and non-binding on the Board. The alternative among one

year, two years, or three years that receives the highest number of votes cast by the holders of

shares of our common stock present virtually or represented by proxy at the Annual Meeting and

entitled to vote thereon will be deemed to be the frequency preferred by our stockholders.

Abstentions and broker non-votes will have no effect on the outcome of this proposal.

**Our Board recommends a vote to hold future stockholder advisory votes on the** 

**compensation of our named executive officers every "THREE YEARS."**

**COMPENSATION DISCUSSION AND ANALYSIS**

The purpose of this Compensation Discussion and Analysis is to provide information

about the material elements of compensation that are paid, awarded to, or earned by, our named

executive officers for fiscal year 2025 (whom we collectively refer to as our "NEOs"), who

consist of any individual who served as our principal executive officer during the fiscal year

ended December 31, 2025 (hereinafter, "fiscal year 2025"), any individual who served as our

principal financial officer during fiscal year 2025, and our three most highly compensated

executive officers who were serving at the end of fiscal year 2025 other than our principal

executive officer and principal financial officer.

For fiscal year 2025, our NEOs and their respective positions were:

• Thomas P. Gallagher, Chairman and Chief Executive Officer;

• Lance Emmons, Executive Vice President, Chief Financial Officer;

• Douglas M. Schafer Jr., Executive Vice President, Chief Information Officer;

• Barbara J. Comly, Executive Vice President, General Counsel and Corporate

Secretary; and

• Shelly Brown, Executive Vice President, Chief Strategy Officer, and Chief

Executive Officer of MIAX Futures.

**Compensation Philosophy and Objectives**

Our executive compensation philosophy is to link executive compensation with

individual achievement, company performance and stockholder value creation. Our executive

compensation program is designed to attract, motivate, and retain high-caliber leaders, align pay

with performance and support our long-term strategy with an appropriately balanced mix of fixed

and variable compensation. This is reflected in our following key objectives:

• to attract, retain and reward executive officers capable of achieving our business

objectives;

• to offer competitive compensation opportunities that reward individual

performance and contribution to company performance;

• to align the interests of executive officers and stockholders over the long-term;

and

• to provide a comprehensive compensation package commensurate with

performance achieved and value created for our stockholders.

***Process for Determining Executive Compensation***

The Compensation Committee has overall responsibility for approving and evaluating the

director and executive compensation plans, policies and programs of the Company. The

Compensation Committee uses several different tools and resources in reviewing elements of

executive compensation and making compensation decisions, including our independent

compensation consultant as noted below. These decisions, however, are not purely formulaic,

and the Compensation Committee exercises informed judgment and discretion as appropriate,

taking into consideration our financial results, business culture, strategic goals, and company

initiatives and whether each particular compensation element provides an appropriate incentive

and reward for performance that sustains and enhances long-term stockholder value. Included in

these considerations is an assessment of the NEO's current total compensation, leadership,

dedication, individual performance, prospect for future performance, years of experience, skill

set and contributions to our financial results and the creation of stockholder value as well as the

competitive environment of our industry.

*Role of Executive Officers in Compensation Decisions*

The Compensation Committee considers input from our Chief Executive Officer in

making determinations regarding our executive compensation program and the individual

compensation of each executive officer, other than our Chief Executive Officer. Our Chief

Executive Officer and management team also provide information to the Compensation

Committee regarding the Company's performance for purposes of determining annual cash

bonuses and long-term incentive equity awards. The Compensation Committee makes the final

determination of NEO compensation. Our Chief Executive Officer makes no recommendations

regarding, and does not participate in discussions about, his own compensation.

*Role of Independent Compensation Consultant* 

As part of our transition as a public company, our Compensation Committee retained

Korn Ferry, an independent compensation consultant, in November 2025 to conduct a review of

our then-existing compensation philosophy and programs and to assist the Compensation

Committee in assessing and recommending executive compensation for fiscal year 2026.

**Elements of Compensation**

Our current executive compensation program, which is set by our Compensation

Committee, consists of the following components:

• base salary;

• annual cash bonuses linked to our overall performance;

• periodic grants of long-term equity-based compensation in the form of restricted

stock and stock options;

• other executive benefits and perquisites; and

• employment agreements, which contain certain termination benefits.

We combine these elements in order to formulate compensation packages that provide

competitive pay, reward the achievement of financial, operational and strategic objectives and

align the interests of our executive officers and other senior personnel with those of our

stockholders.

Further detail on each of these components is provided in the table below.

---

| | | |
|:---|:---|:---|
| **Compensation** <br>**Elements**<br>| **Form** | **Objectives** |
| Base Salary | Cash | •Provide a fixed component of compensation reflecting the executive's <br>skill set, experience, role and responsibilities.<br>•Recruit and retain qualified executives by providing regular, stable <br>compensation for their service throughout the year.<br>|
| Annual Cash Bonuses  | Cash | •Incentivize our NEOs to achieve Company business goals.<br>•Reward NEOs for their contributions toward the achievement of these <br>goals.<br>|
| Long-term Equity <br>Incentive Awards<br>| Equity | •Provide our NEOs with a strong link to our long-term performance.<br>•Create an ownership culture and help to align the interests of our <br>NEOs and our stockholders.<br>•Enhance executive retention.<br>|

---

***Pay Mix***

We utilize the elements of compensation described above because we believe that such

elements provide a well-proportioned mix of secure compensation, retention value and at-risk

compensation that produces short-term and long-term performance incentives and rewards. By

following this approach, we provide our NEOs with a measure of security in the minimum

expected level of compensation, while motivating our NEOs to focus on business metrics that

will produce a high level of short-term and long-term performance for the Company and long-

term wealth creation for each NEO, as well as reducing the risk of recruitment of our top

executive talent by our competitors.

For our NEOs, total compensation consists of both fixed pay and at-risk pay (annual

incentives and long-term incentives). Maintaining this pay mix results fundamentally in a pay-

for-performance orientation for our NEOs, which is aligned with our stated compensation

philosophy of providing compensation commensurate with performance.

***Base Salary***

Base salary payable to our NEOs is intended to provide a fixed component of

compensation reflecting the NEO's skill set, experience, role and responsibilities. Base salaries

are reviewed annually, typically in connection with our annual performance review process, and

may be adjusted from time to time to realign with market levels after taking into account

individual responsibilities, performance and experience. Our Compensation Committee

determines market level compensation for base salaries based on our NEOs' experience in the

industry with reference to the base salaries of similarly situated executives in other companies of

similar size and stage of development operating in our industry.

With these principles in mind, base salaries are reviewed during the first half of the fiscal

year by our Compensation Committee and may be adjusted from time to time based on the results

of this review.

The annualized base salaries paid to our NEOs in fiscal year 2024 and fiscal year 2025

are set forth in the chart below.

---

| | | | |
|:---|:---|:---|:---|
| **Named Executive Officer** | **Fiscal Year 2024**<br>**Base Salary ($)**<br>| **Fiscal Year 2025**<br>**Base Salary ($)**<br>| **Percent** <br>**Increase**<br>|
| Thomas P. Gallagher .................................... | 2500000 | 2500000 | 0% |
| Lance Emmons ............................................. | 750000 | 790000 | 5% |
| Douglas M. Schafer Jr. ................................. | 1900000 | 2100000 <sup>(1)</sup> | 11% |
| Barbara J. Comly .......................................... | 1550000 | 1627500 | 5% |
| Shelly Brown ................................................ | 700000 | 728000 | 4% |

---

(1)The increase in the base salary of Mr. Schafer took into account the growing number of exchange platforms that

were being built and operated under his leadership from the original four fully electronic MIAX Exchanges, to

the additional MIAX Futures clearing and trading platforms, BSX platforms and the MIAX Sapphire trading

floor.

Base salary increases as shown in the table above became effective on April 1, 2025.

***Bonus***

*Annual Cash Bonuses*

On an annual basis, our NEOs are eligible to receive discretionary cash bonuses,

determined, in the case of our Chief Executive Officer, in the discretion of the Compensation

Committee, and for each of our other NEOs, by the Compensation Committee in consultation

with our Chief Executive Officer. Such discretionary bonuses are determined and paid in

recognition of both company and individual performance during the fiscal year. In addition, each

of Messrs. Emmons, Schafer and Brown and Ms. Comly is eligible to receive a guaranteed

minimum annual bonus in an amount equal to $200,000, $1,000,000, $250,000 and $400,000,

respectively.

*Special Bonuses*

During fiscal year 2025, our NEOs were also eligible to earn other special bonuses in

recognition of achievement of certain strategic or corporate milestones, as set forth below.

• *IPO bonus*. Each of our NEOs was eligible to receive a one-time special bonus in

connection with the completion of our IPO (for Mr. Brown, such bonus amount

was equal to $650,000, which included $400,000 as provided for by his

employment agreement and an additional amount of $250,000 awarded to him in

recognition for his extraordinary contribution to the IPO and, for each of the other

NEOs, such bonus amount was equal to $1,000,000). All of the IPO bonuses were

paid within 45 days after the effective date of the IPO.

• *Special bonus upon launch or acquisition of securities exchange*. Each of Mr.

Emmons and Ms. Comly is eligible to receive a special bonus in the amount of

$250,000 upon the acquisition or launch by the Company of a new securities

exchange, whether through organic growth or acquisition. Each of Mr. Emmons

and Ms. Comly received this special bonus in 2025 in connection with the

acquisition of TISEG.

• *Other bonus pool*. Pursuant to their employment agreements, each of Messrs.

Gallagher and Schafer and Ms. Comly is eligible to participate in a technology

bonus pool, and each of Mr. Gallagher and Ms. Comly is eligible to participate in

an annual cash bonus pool based on achievement of EBITDA goals, neither of

which bonus pools is funded or in effect in fiscal year 2025.

***Long-Term Equity-Based Compensation***

We believe that equity grants provide our NEOs with a strong link to our long-term

performance, create an ownership culture, help to align the interests of our NEOs and our

stockholders and enhance executive retention. Our Compensation Committee reviews the equity

incentive compensation of our executives and may grant equity incentive awards to them from

time to time. The amount and terms of any grant are determined at the discretion of the

Compensation Committee. Additional details on equity awards are set forth in the Fiscal Year

2025 Grants of Plan-Based Awards Table and Outstanding Equity Awards at 2025 Fiscal Year-

End Table below.

We maintain the following stock incentive plans (collectively, the "Prior Stock Incentive

Plans") under which stock options and restricted stock awards have been granted to our

employees and other service providers, including the NEOs and non-employee members of our

Board: (i) the 2008 Stock Incentive Plan ("2008 Plan"), (ii) the 2008 Stock Incentive Plan for

Non-Employee Directors and Members of the Board of Advisors ("2008 Director Plan"), (iii) the

2013 Stock Option and Incentive Plan for Employees and Consultants ("2013 Plan"), (iv) the

2013 Stock Option and Incentive Plan for Non-Employee Directors, Committee Members and

Members of the Board of Advisors ("2013 Director Plan") and (v) the 2021 Stock Option and

Incentive Plan for Employees and Consultants ("2021 Plan").

Effective May 16, 2022, our Board adopted the 2022 Equity Incentive Plan (the "2022

Plan" and, together with the Prior Stock Incentive Plans, the "Equity Plans") and amended each

of the Prior Stock Incentive Plans such that all shares of our nonvoting common stock or Series

B preferred stock subject to awards under such Prior Stock Incentive Plans converted into shares

of our voting common stock in connection with the IPO. Effective upon the adoption of the 2022

Plan, no further awards may be granted under any of the Prior Stock Incentive Plans.

On June 16, 2025, the Compensation Committee approved long-term equity awards

under the 2022 Plan for our NEOs for fiscal year 2025. Such equity awards consisted of stock

options (and shares of restricted stock, for Mr. Gallagher and Ms. Comly), which generally vest

as follows:

• *Incentive Stock Options and Nonqualified Stock Options*. One-third of the

underlying shares vest on each of first three anniversaries of the date of grant,

subject to acceleration of vesting in full upon a Change in Control (as defined in

the 2022 Plan and set forth below in the section titled "Potential Payments Upon

Termination or Change in Control - Summary of Defined Terms") and further

subject to the NEO's continuous service to the Company through each applicable

vesting date.

• *Restricted Stock*. The shares of restricted stock vest on the earlier to occur of the

one-year anniversary of the closing of the IPO and a Change in Control, subject to

acceleration of vesting in full upon a termination of the NEO's employment by us

without "Cause" or by the NEO for "Good Reason" (each as defined in the

appliable employment agreement, as set forth below in the section titled

"Potential Payments Upon Termination or Change in Control - Summary of

Defined Terms") and further subject to the NEO's continuous service to the

Company through the applicable vesting date.

The following table displays the number of stock options and shares of restricted stock

approved by the Compensation Committee for our NEOs in fiscal year 2025.

(1)Includes nonqualified stock options and restricted stock held by Gallagher Investments LLC ("Gallagher

Investments") of which Mr. Gallagher maintains beneficial ownership.

***Other Executive Benefits and Perquisites***

We provide the following benefits to our executive officers on the same basis as other

eligible employees:

• health and welfare benefit plans;

• vacation and sick days;

• life insurance, supplemental life and disability insurance; and

• a 401(k) plan with discretionary matching contributions (50% of eligible

contributions up to the first 6% of compensation).

We believe these benefits are generally consistent with those offered by other companies

and specifically with those companies with which we compete for employees.

Pursuant to the applicable NEO's employment agreement, we also provide executive life

insurance to each of our NEOs, car allowances to Messrs. Gallagher and Schafer and Ms. Comly,

a housing allowance for Mr. Schafer and limited tax gross-ups for Mr. Gallagher and Ms. Comly

in the event any of his or her payments or benefits under their respective employment agreements

are subject to excise tax under Section 4999 of the Internal Revenue Code. We also provide tax

gross-ups to each of our NEOs under our Transaction Incentive Plan (the "TIP") in the event

payments thereunder are subject to excise tax under Section 4999 of the Internal Revenue Code.

Other than the 401(k) plan, we do not provide any qualified or non-qualified retirement or

deferred compensation benefits to our employees, including our NEOs. For further details, see

the section below titled "Narrative Description to the Fiscal Year 2025 Summary Compensation

Table and the Grants of Plan-Based Awards Table for the 2025 Fiscal Year – Other Benefit

Plans."

**Agreements with Named Executive Officers**

We believe that a strong, experienced management team is essential to the best interests

of the Company and our stockholders. To achieve our goal of attracting and retaining high-

quality executive talent and to minimize any distraction in connection with a Change in Control,

which could be detrimental to the Company and our stockholders, we have entered into

employment agreements with each of our NEOs, which provide for severance benefits in

connection with a termination of employment. For a description of such employment agreements

and our obligations under the employment agreements in the event of a termination of

employment or Change in Control, see the sections below titled "Narrative Description to the

Fiscal Year 2025 Summary Compensation Table and the Grants of Plan-Based Awards Table for

the 2025 Fiscal Year - Employment Agreements" and "Potential Payments Upon Termination or

Change in Control - Severance Benefits under Employment Agreements." In addition, each of

our NEOs is also eligible to receive payments in connection with a Change in Control pursuant

to the TIP, as described in further detail below in the section titled "Potential Payments upon

Termination or Change in Control - Transaction Incentive Plan."

***Policies and Practices for Granting Certain Equity Awards***

In order to ensure consistency in the design of executive compensation, our Board and

Compensation Committee strive to grant all annual equity awards to executive officers, including

stock options, in the first half of each year. Our Board and Compensation Committee do not take

material non-public information into account when determining the timing and terms of awards

and maintain a policy against any timing of disclosure of material non-public information for the

purpose of affecting the value of any executive compensation.

**Fiscal Year 2025 Summary Compensation Table**

The following table sets forth certain information with respect to compensation earned

***Potential Payments Upon Termination or Change in Control***

*Severance Benefits under Employment Agreements*

In the event of a termination of employment by us without Cause or by the NEO for

Good Reason (summaries of such definitions provided below), our NEOs are entitled to the

following severance benefits, besides accrued benefits and business expense reimbursements:

• *Mr. Gallagher and Ms. Comly*: Each of Mr. Gallagher and Ms. Comly is entitled

to (i) continued base salary through the earlier of the end of the employment term

or February of the year following the year of termination, and on March 1 of the

year following the year of termination, the NEO will receive a lump-sum payment

equal to the remaining base salary that would have been payable through the end

of the employment term (reduced by salary continuation payments already made),

plus any accrued but unpaid cash bonuses and any discretionary bonus and (ii)

continued health care coverage fully subsidized by the Company for up to 12

months following termination, or, if shorter through the remainder of the

employment term, with the cost of coverage provided on at least a monthly basis.

• *Messrs. Emmons, Schafer and Brown*: Each of Messrs. Emmons, Schafer and

Brown is entitled to (i) continued base salary through the end of the employment

term; (ii) within 30 days following termination, a lump-sum payment equal to the

minimum annual bonus that would have been payable for the remainder of the

employment term and (iii) continued health care coverage, with the Company

portion paid by the Company, for up to 12 months following termination, or, if

shorter through the remainder of the employment term. The entitlement to

severance payments is subject to the NEO's execution and non-revocation of a

release of claims in favor of us and continuing compliance with their restrictive

covenants.

In the event of a termination of employment by us without Cause or by the NEO for

Good Reason that occurs within the six months preceding or two years following a Change in

Control (the "Change in Control Period") (for Ms. Comly, a "Corporate Transaction" as defined

in the 2013 Plan and summarized below), our NEOs are entitled to the following enhanced

severance benefits, besides accrued benefits and business expense reimbursements:

• *Mr. Gallagher and Ms. Comly*: Each of Mr. Gallagher and Ms. Comly is entitled

to, within 30 days following termination, a lump-sum payment equal to the base

salary and bonuses that would have been payable through the remainder of the

employment term or, if greater, over the 24-month period following termination.

In addition, each of Mr. Gallagher and Ms. Comly is entitled to a tax gross-up

payment if any of his or her payments or benefits are subject to an excise tax

under Section 4999 of the Internal Revenue Code, but such tax gross-up payment

is capped at an amount equal to his or her base salary paid to him or her for the

year prior to the year of termination.

• *Messrs. Emmons, Schafer and Brown*: Each of Messrs. Emmons, Schafer and

Brown is entitled to the severance benefits described above, except that for the

purposes of determining the duration of the severance period, the date on which

the employment term would have expired will be deemed to be the longer of (x)

the end date of his employment term and (y) the second anniversary of the date of

such termination. The entitlement to severance payments is subject to the NEO's

execution and non-revocation of a release of claims in favor of us and continuing

compliance with their restrictive covenants. Each of the Emmons Employment

Agreement, the Schafer Employment Agreement and the Brown Employment

Agreement provides for a "best-net" cutback in the event any payment to which

the NEO is entitled thereunder constitutes a "parachute payment" under Section

280G of the Internal Revenue Code.

Messrs. Emmons, Schafer and Brown, a violation of the federal securities, commodities futures

or other applicable laws.

"Good Reason" means (i) material diminution of the NEO's authority, duties and

responsibilities, which change would cause the NEO's position to become one of (for Messrs.

Emmons, Schafer and Brown, materially) less responsibility, importance and scope, (ii) material

reduction of the NEO's base salary, as it may be increased from time to time, (iii) certain adverse

changes in the geographic location at which the NEO must perform his or her services; or (iv)

in Control"), provided that such participant either: (i) has not incurred a termination of service as

of the day immediately prior to the TIP Change in Control, or (ii) has been terminated without

Cause or due to death or disability, in either case, within 75 days prior to the TIP Change in

Control. Amounts payable under the TIP must be paid in a lump sum within 30 days of the TIP

Change in Control. The TIP may be administered by the Compensation Committee, our Board,

or their delegates, subject to applicable laws, and the administrator of the TIP may make

payment under the TIP contingent upon the execution of a release of claims in our favor. The

bonus pool that our NEOs may participate in is based on the Transaction Proceeds and

Transaction Enterprise Value (both as defined in the TIP) as follows:

allocations: 24% for Mr. Gallagher, 18% for Mr. Schafer and Ms. Comly, 14% for Mr. Emmons

and 10% for Mr. Brown, in each case, as set forth in their respective TIP Award Agreement. In

addition, they are entitled to a tax gross-up payment if any of the payments under the TIP are

subject to the excise tax under Section 4999 of the Internal Revenue Code.

"TIP Change in Control" means (i) the acquisition, directly or indirectly, by any person

or group of beneficial ownership in the Company representing more than 50% of the total

combined voting power of all outstanding interests of the Company; (ii) a merger, consolidation,

or other similar transaction involving the Company, except for a transaction in which the holders

of the outstanding voting interests of the Company immediately prior to the merger,

consolidation, or other transaction hold, in the aggregate, securities possessing more than 50% of

the total combined voting power of all outstanding voting securities of the surviving entity after

such transaction; or (iii) a sale or other disposition of all or substantially all of the assets of the

Company.

measurement point (i.e., August 14, 2025, the date we became a publicly traded company) on the same

cumulative basis as is used in Item 201(e) of Regulation S-K.

The peer group used to determine the Company's Peer Group TSR for each applicable fiscal year is a

customized peer group of four companies, which is the same peer group disclosed in our Annual Report on

Form 10-K for fiscal year 2025 and is comprised of the following: Cboe, CME Group Inc, ICE and Nasdaq.

(5)Represents the amount of net loss reflected in the Company's audited GAAP financial statements for each

applicable fiscal year.

(6)We have selected Adjusted EBITDA as our most important financial measure (that is not otherwise required to

be disclosed in the table) used to link 'compensation actually paid' to our NEOs to company performance for

fiscal year 2025. Adjusted EBITDA, a non-GAAP financial measure, is defined as net income before interest,

income taxes, depreciation, amortization, and certain items of income and expense that are not considered

representative of the Company's core operating performance.

(7)For fiscal year 2025, the 'compensation actually paid' to our NEOs reflects each of the following adjustments

made to the total compensation amounts reported in the Fiscal Year 2025 Summary Compensation Table,

computed in accordance with Item 402(v) of Regulation S-K:

made relating thereto.

***Pay versus Performance Comparative Disclosure***

As described in the Compensation Discussion and Analysis section, we do not utilize

specific financial metrics or predetermined performance targets as the basis for determining

executive compensation. Rather, the Compensation Committee takes a holistic approach,

exercising its informed judgment to evaluate a broad range of factors when determining annual

cash bonus payouts and annual equity award grants. These factors include, but are not limited to,

the Company's overall financial performance, stock price performance, industry-specific and

broader macroeconomic conditions affecting our business and competitive environment and the

individual performance and contributions of each of our NEOs.

The chart below illustrates the relationship between the amount of compensation actually

paid to the PEO and the average amount of compensation actually paid to the Company's other

NEOs and the Company's TSR and the Company's Peer Group TSR during 2025 assuming $100

initial investment on August 14, 2025.

![CAP vs TSR GIF.gif](miax-20260426_g23.gif)

The charts below illustrate the relationship between the PEO and other NEOs average

compensation actually paid amounts and the Company's Net Income (Loss) and Adjusted

EBITDA during 2025.

with the SEC's rules, will not be deemed to be part of or incorporated by reference by any

general statement incorporating by reference this Proxy Statement into any filing under the

Securities Act of 1933, as amended ("Securities Act") or under the Exchange Act, except to the

extent that we specifically incorporate this information by reference, and will not otherwise be

deemed "soliciting material" or "filed" under either the Securities Act or the Exchange Act.

The Compensation Committee consists of Mr. Talal Jassim Al-Bahar (Chair), Mr. Mark

under NYSE listing rules. The Compensation Committee has duties and powers as described in

its written charter adopted by the Board. A copy of the charter can be found on our investor

relations page at http://ir.miaxglobal.com. The information on our website is not intended to

form a part of or be incorporated by reference into this Proxy Statement.

Our Compensation Committee has reviewed and discussed the Compensation Discussion

**PROPOSAL NO. 4:**

**RATIFICATION OF APPOINTMENT**

**OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

Our Audit Committee has selected KPMG as our independent registered public

accounting firm to perform the audit of our consolidated financial statements for the year ending

December 31, 2026. KPMG has served as our independent registered public accounting firm

since 2021 and audited our consolidated financial statements for the year ended December 31,

2025. At the Annual Meeting, our stockholders are being asked to ratify the appointment of

KPMG as our independent registered public accounting firm for the year ending December 31,

2026. Although not required by applicable law or listing rules, our Audit Committee is

submitting the appointment of KPMG to our stockholders because we value our stockholders'

views on our independent registered public accounting firm and as a matter of good corporate

governance. A representative of KPMG is expected to be present at the Annual Meeting and will

have an opportunity to make a statement at the Annual Meeting, if they desire to do so, and we

expect that they will be available to respond to appropriate questions. Notwithstanding the

appointment of KPMG, and even if our stockholders ratify the appointment, our Audit

Committee, in its discretion, may appoint another independent registered public accounting firm

at any time during our fiscal year if our Audit Committee believes that such a change would be

in the best interests of our Company and our stockholders.

In the event that KPMG is not ratified by our stockholders, the Audit Committee may

reconsider their selection of KPMG as our independent registered public accounting firm.

**Independent Registered Public Accounting Firm Fees and Services**

We regularly review the services and fees from our independent registered public

accounting firm. These services and fees are also reviewed with our Audit Committee. In

accordance with standard policy, KPMG periodically rotates the individuals who are responsible

for our audit.

In addition to performing the audit of our consolidated financial statements, KPMG

provided various other services during the years ended December 31, 2025 and 2024. Our Audit

Committee has determined that KPMG's provision of these services, which are described below,

does not impair KPMG's independence from us. During the years ended December 31, 2025 and

2024, fees for services provided by KPMG were as follows:

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Audit fees<sup>(1)</sup> ........................................................................... | $3809931 | $2919054 |
| Audit-related fees<sup>(2)</sup> .............................................................. | 514500 |  |
| Tax fees<sup>(3)</sup> ............................................................................. | 436588 | 383830 |
| All other fees<sup>(4)</sup> ..................................................................... |  | 10000 |
| Total fees .............................................................................. | $4761019 | $3312884 |

---

(1)Fees billed, or expected to be billed, for our annual audit and quarterly review procedures

and fees related to services for other regulatory filings.

(2)Fees billed, or expected to be billed, for assurance and related services.

(3)Fees billed, or expected to be billed, for tax compliance, tax advice, and tax planning

services.

(4)All other fees for permitted services other than those described above.

**Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of** 

**Independent Registered Public Accounting Firm**

Our Audit Committee has established a policy that requires their advance approval of all

audit and permitted non-audit and tax services that may be provided by our independent auditors,

prior to our receipt of such services in order to ensure that the provision of such services does not

impair the independent registered public accounting firm's independence. These services may

include audit services, audit-related services, tax services, and other services. The independent

registered public accounting firm and management are required to periodically report to the

Audit Committee regarding the extent of services provided by the independent registered public

accounting firm in accordance with this pre-approval, and the fees for the services performed to

date.

All of the services relating to the fees described in the table above in 2025, the year in

which we completed our IPO, were approved by our Audit Committee. Additional information

may be found in the Audit Committee's charter, which can be found on our investor relations

page at http://ir.miaxglobal.com. The information on our website is not intended to form a part of

or be incorporated by reference into this Proxy Statement.

**Vote Required**

The ratification of the appointment of KPMG as our independent registered public

accounting firm for the year ending December 31, 2026 requires the affirmative vote of the

holders of a majority of the total number of votes of our common stock present virtually or

represented by proxy at the Annual Meeting and entitled to vote thereon that are voted "FOR" or

"AGAINST" the proposal. Abstentions will have the same effect as a vote "AGAINST" the

proposal. Because this proposal is a routine matter pursuant to the NYSE's Rule 452, brokers

have discretion to vote uninstructed shares on this matter and as such we do not expect broker

non-votes on this proposal.

**Our Board recommends that you vote "FOR" the ratification of the appointment of KPMG** 

**as our independent registered public accounting firm for the year ending December 31,** 

**2026.** 77

**REPORT OF THE AUDIT COMMITTEE**

This report of the Audit Committee is required by the SEC and, in accordance with the

SEC's rules, will not be deemed to be part of or incorporated by reference by any general

statement incorporating by reference this Proxy Statement into any filing under the Securities

Act or under the Exchange Act, except to the extent that we specifically incorporate this

information by reference, and will not otherwise be deemed "soliciting material" or "filed" under

either the Securities Act or the Exchange Act.

Our Audit Committee is composed entirely of independent directors who meet the

independence requirements under the NYSE and the SEC. Our Audit Committee assists our

Board in its oversight of our accounting practices, system of internal controls regarding finance,

accounting and legal compliance, audit processes, and financial reporting processes. Our Audit

Committee is responsible for appointing and retaining our independent auditor and approving the

audit, permitted non-audit and tax services to be provided by the independent auditor. Our Audit

Committee's function is more fully described in its charter.

Our Audit Committee has reviewed and discussed with our management and KPMG our

audited consolidated financial statements for the year ended December 31, 2025. Our Audit

Committee has also discussed with KPMG the matters required to be discussed by the applicable

requirements of the Public Company Accounting Oversight Board (United States) (the

"PCAOB") and the SEC.

Our Audit Committee has received and reviewed the written disclosures and the letter

from KPMG required by applicable requirements of the PCAOB regarding the independent

accountant's communications with our Audit Committee concerning independence, and has

discussed with KPMG its independence from us.

Based on the review and discussions referred to above, our Audit Committee

recommended to our Board that the audited consolidated financial statements be included in our

Annual Report on Form 10-K, for filing with the SEC.

reports of changes in ownership with the SEC. Such persons are required by SEC regulation to

furnish us with copies of all Section 16(a) forms that they file. Based solely on our review of the

copies of such forms furnished to us and written representations from the directors and executive

officers, we believe that all Section 16(a) filing requirements were timely met in the year ended

December 31, 2025, except, due to administrative error, for one late Form 4 filing made on

behalf of Murray Stahl, a former director, dated September 30, 2025, to include HKAM as an

additional reporting person.

**CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS**

The following is a summary of transactions we have entered into since January 1, 2025,

officers, directors, or holders of more than 5% of any class of our voting securities (current and

former), or any affiliate or member of the immediate family of any of the foregoing persons, had

or will have a direct or indirect material interest, other than the compensation and other

arrangements we describe under "Compensation Discussion and Analysis."

**Transactions with Greater than 5% Holders (Current and Former) and Related Parties**

***Trading Activity with Exchange Members***

Certain beneficial owners and former beneficial owners of more than 5% of our common

stock during the period since January 1, 2025 are or have been our customers, including Citadel

Securities Principal Investments LLC ("Citadel Securities"), Susquehanna Securities, LLC and

Wolverine Holdings, LP ("Wolverine").

We receive revenues and incur cost of revenues related to trading and membership

activity on our markets by these parties. These fees are assessed pursuant to our published fee

the SEC, to customers and recognize an equivalent amount as revenue.

The aggregate revenues and cost of revenues that we received from these parties, each

excluding pass-through Section 31 fees, are summarized in the tables below. Such fees and

payments have at all times been on terms no more favorable than those to other customers.

after deducting upfront fees. Prior to the second anniversary of the loan, the lenders, at their sole

discretion, could make additional term loans to the Company in an aggregate amount of up to

$100 million. The 2029 Senior Secured Term Loan was due to mature on August 21, 2029. As

2029. On August 18, 2025, we repaid all outstanding indebtedness ($140,000,000), plus accrued

and unpaid interest ($2,458,167), related premium and fees ($35,982,333) under the 2029 Senior

The compensation levels of the individuals described above are consistent with those of

our other employees with similar years of experience and positions within the Company who are

not related to our executive officers and directors. The individuals described above also

participate in our benefit plans and are eligible for equity awards on the same general terms and

conditions as applicable to all other employees in similar positions who are not related to our

executive officers and directors.

**Limitation of Directors' and Officers' Liability and Indemnification**

As permitted by Section 102(b)(7) of the Delaware General Corporation Law (the

"DGCL"), our Amended and Restated Certificate of Incorporation includes a provision that

eliminates the personal liability of our directors for monetary damages for any breach of their

fiduciary duties as directors, to the fullest extent permitted by the DGCL.

We have directors' and officers' liability insurance to cover liabilities our directors and

executive officers may incur in connection with their services to us. Our Amended and Restated

Certificate of Incorporation and Amended and Restated By-Laws require us to indemnify

members of our Board and of our Committees, as well as our executive officers, and may

indemnify other officers, agents and employees, and any persons serving another corporation,

partnership, joint venture, trust or other enterprise at our request, in each case to the maximum

extent permitted by the DGCL; provided, however, that we may limit the extent of such

indemnification by individual contracts with our directors and executive officers; and provided,

further, that we will not be required to indemnify any person in connection with any proceeding

(or part thereof) initiated by such person or any proceeding by such person against us or our

directors, officers, employees or other agents unless (i) such indemnification is expressly

required to be made by law, (ii) the proceeding was authorized by our Board, or (iii) such

indemnification is provided by us, in our sole discretion, to the extent permitted by the DGCL.

Our Amended and Restated By-Laws also require us to advance to any person who was

or is a party or is threatened to be made a party to any threatened, pending or completed action,

suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact

that such person is or was a director or executive officer or is or was serving as a director or

executive officer of another corporation, partnership, joint venture, trust or other enterprise at our

request, prior to the final disposition of the proceeding, promptly following such person's

request, all expenses incurred by such person in connection with such proceeding upon receipt of

an undertaking by or on behalf of such person to repay any amounts advanced by us if it is

ultimately determined that such person is not entitled to be indemnified; provided, however, that

we will not be required to advance any expenses to any person who our Board determines has

acted in bad faith or in a manner that such person did not believe to be in or not opposed to the

best interests of our Company.

We have entered into indemnification agreements with each of our directors and

executive officers. These agreements provide that we will, among other things, indemnify and

advance expenses to our directors and executive officers for certain expenses, including

attorneys' fees, judgments, fines and settlement amounts incurred by any such person in any

action or proceeding, including any action by us arising out of such person's services as our

director or officer, or any other company or enterprise to which the person provides services at

our request. We believe that these provisions and agreements are necessary to attract and retain

qualified persons as directors and executive officers.

Such limitation of liability and indemnification does not affect the availability of

equitable remedies. In addition, we have been advised that in the opinion of the SEC,

indemnification for liabilities arising under the Securities Act is against public policy as

expressed in the Securities Act and is therefore unenforceable.

**Related Person Transaction Policy**

Our Board adopted a written related person transaction policy, setting forth the policies

and procedures for the review and approval or ratification of related person transactions. This

policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the

Securities Act, any transaction, arrangement, or relationship, or any series of similar transactions,

arrangements, or relationships, in which we were or are to be a participant, where the amount

involved exceeds $120,000 in any fiscal year and a related person had, has, or will have a direct

or indirect material interest, including without limitation, purchases of goods or services by or

from the related person or entities in which the related person has a material interest,

indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing

and approving any such transactions, our Audit Committee has the primary responsibility for

considering all relevant facts and circumstances, including, but not limited to, whether the

transaction is on terms comparable to those that could be obtained in an arm's length transaction

and the extent of the related person's interest in the transaction.

**APPENDIX - RECONCILIATION OF NON-GAAP FINANCIAL MEASURES TO GAAP** 

**MEASURES**

In addition to results presented in accordance with GAAP, we disclose certain non-GAAP

financial measures in this Proxy Statement. These financial measures are not prepared in

accordance with, or as a substitute for, GAAP financial measures and may differ from similarly

titled measures used by other companies. The non-GAAP measures provided in this Proxy

management to evaluate operating performance and support compensation decisions by

excluding items that may not reflect our underlying business performance. We believe that

presenting these measures provides investors with useful information as to how management

assesses performance and aligns executive compensation with Company results.

Reconciliations of the non-GAAP measures to the most directly comparable GAAP

measures are provided below.
