PROXY STATEMENT

ANNUAL MEETING OF STOCKHOLDERS

April 23, 2026

INTRODUCTION

This Proxy Statement is furnished in connection with a solicitation of proxies by the Board of Directors (the “Board”) of Interactive Brokers Group, Inc. (“IBG, Inc.”), a Delaware corporation, to be used at our 2026 Annual Meeting of Stockholders (the “Annual Meeting”) and at any adjournments or postponements of the Annual Meeting. The Annual Meeting will be held on Thursday, April 23, 2026 at 9:30 a.m., Eastern Time, and will be held as a virtual meeting at www.virtualshareholdermeeting.com/IBKR2026. You may access the virtual meeting using the multi-digit Control Number provided with your proxy materials. This Proxy Statement and the accompanying form of proxy are first being made available on or about March 13, 2026.

When we use the terms “Company,” “we,” “us” and “our,” we mean Interactive Brokers Group, Inc., a Delaware corporation, its consolidated subsidiaries and predecessor companies.

On April 15, 2025, the Company announced its intention to effect a four-for-one forward split of its common stock in the form of a stock dividend. This was executed by the filing of an amendment to the Company’s Certificate of Incorporation, which was approved by the Company’s Board of Directors and the Company’s majority stockholder on April 14, 2025 and on April 22, 2025, respectively, that, among other things (i) increased the Company’s authorized shares of Class A common stock to 4,000,000,000 shares from 1,000,000,000 shares and (ii) increased the Company’s authorized shares of Class B Common Stock to 1,000 shares from 100 shares to accommodate the stock split. Each holder of record of common stock as of the close of market on June 16, 2025, received three additional shares of common stock. All shares, per share amounts and stock incentive awards presented herein are on a post-split basis.

VOTING INSTRUCTION AND INFORMATION

Why did I receive a Notice regarding the Availability of Proxy Materials?

In accordance with Securities and Exchange Commission (“SEC”) rules, instead of mailing a printed copy of our proxy materials, we may send a Notice of Internet Availability of Proxy Materials (the “Notice”) to stockholders. All stockholders will have the ability to access the proxy materials on a website referred to in the Notice or to request a printed set of these materials at no charge. You will not receive a printed copy of the proxy materials unless you specifically request one. Instead, the Notice instructs you as to how you may access and review all of the important information contained in the proxy materials via the Internet and submit your vote via the Internet or telephonically.

In addition, you may request to receive future proxy materials on an ongoing basis (i) electronically by e-mail or (ii) in printed form by mail. Choosing to receive future proxy materials by e-mail will save the Company the cost of printing and mailing documents to stockholders and will reduce the impact of annual meetings on the environment. Your election to receive proxy materials by e-mail or by mail will remain in effect until you terminate it.

Who can vote at the Annual Meeting?

You are entitled to vote your shares of Class A common stock, par value $0.01 per share (the “common stock”), of the Company if you were a stockholder at the close of business on February 24, 2026, the record date for the Annual Meeting. At the close of business on the record date, 445,616,477 shares of common stock were outstanding. In addition, 400 shares of Class B common stock, par value $0.01 per share (the “Class B common stock”), of the Company were outstanding. All of the outstanding shares of Class B common stock are held of record by IBG Holdings LLC (“Holdings”), an entity controlled by Mr. Thomas Peterffy, our founder and Chairman, through his indirect ownership of the voting membership interests in Holdings.

The holders of the common stock and the Class B common stock will vote together as a single class on each of the proposals described in this Proxy Statement. The holder of each share of the common stock is entitled to one vote per share.

Due to our “Up-C” corporate structure, Mr. Thomas Peterffy and his affiliates, management and other employees of IBG LLC (the “Holdings Members”) maintain their ownership in the Company through membership interests in Holdings (the “Holdings Interests”). In order to ensure that the Holdings Members are not disenfranchised and, therefore, are entitled to vote their economic interest in the Company, Holdings was granted shares of Class B common stock that are proportionate to the voting power held by the Company’s Class A common shares. The Class B common shares are, in turn, voted on behalf of the Holdings Members by Mr. Thomas Peterffy, who directly or indirectly owns all of the voting membership interests in Holdings.

The Holdings Members’ ownership of interests in Holdings is proportionate to their economic interests held through Holdings in IBG LLC, the holding company for our businesses. The Class B common shares do not provide any voting power in excess of the Holdings Members’ economic interest in the Company. Rather, the Class B common shares merely enable Mr. Thomas Peterffy to vote the Holding Members’ proportionate economic interest in the Company on their behalf and does not give disproportionate or supervoting rights to Holdings or its members by virtue of owning Class B common stock. The number of votes cast by the Class B common stock is the same number of votes as the Holdings Members would cast if their Holdings Interests were exchanged for shares of Class A common stock. Accordingly, the Class B common stock is voted on an ‘as-converted’ to Class A common stock basis and does not have superior voting power. Whereas some companies with a dual-class stock voting structure give certain stockholders supervoting stock that has multiple votes per share, we do not. On this basis, each share of the Class B common stock is entitled to 3,126,844 votes, which is equal to the number of membership interests in IBG LLC held on the record date divided by 400. Accordingly, Holdings, as the sole holder of the Class B common stock, is expected to be entitled to cast 1,250,737,416 votes in the aggregate, or approximately 73.7% of all votes eligible to be cast at the Annual Meeting.

As of March 9, 2026, our directors and named executive officers beneficially owned an aggregate of approximately 12,491,219 shares of common stock and restricted stock unit awards (“stock awards”) that vest within 60 days, constituting approximately 2.80% of the common stock outstanding as of such date. As of the record date, February 24, 2026, our directors and named executive officers owned an aggregate of approximately 11,647,546 shares which can be voted at the Annual Meeting and constituting approximately 0.69% of all votes eligible to be cast at the Annual Meeting. It is expected that such directors and named executive officers will vote or direct the vote of all shares of common stock held or owned by such persons, or over which such persons have voting control, in favor of the proposals described in this Proxy Statement. It also is expected that Holdings will vote its shares of Class B common stock, expected to constitute approximately 73.7% of all votes eligible to be cast at the Annual Meeting, in favor of the proposals. Accordingly, the

Table of Contents

voting power of Holdings alone is sufficient to assure the approval of the proposals. See “Beneficial Ownership of Directors, Named Executive Officers and Owners of More Than Five Percent.”

Who is and is not a stockholder of record?

•

If you hold shares of common stock registered in your name at our stock transfer agent, Computershare Stockholder Services, Inc. (“Computershare”), you are a stockholder of record.

•

If you hold shares of common stock indirectly through a broker, bank or similar institution, you are not a stockholder of record, but instead hold in “street name.”

If you are a stockholder of record, Broadridge is sending these proxy materials to you directly. If you hold shares in street name, these materials are being sent to you by the bank, broker or similar institution through which you hold your shares.

What do I need to do to attend the Annual Meeting?

The Annual Meeting will be held as a virtual meeting. To access the meeting you will need the multi-digit Control Number provided with your proxy materials.

How do I request paper copies of the proxy materials?

If you received a Notice by mail, you will not receive paper copies of the proxy materials in the mail unless you request them. Instead, the Notice instructs you on how to access and read the Proxy Statement and Annual Report and how you may submit your proxy over the Internet. If you received a Notice by mail and would like to receive a printed copy of the materials, please follow the instructions on the Notice for requesting the materials, and we will promptly mail the materials to you.

How do I vote?

You may vote using any of the following methods:

•

Telephone

If you are located within the United States or Canada, you can vote your shares by telephone by calling the toll-free telephone number printed on the Notice, on your proxy card, or in the instructions that accompany your proxy materials, as applicable, and following the recorded instructions. You will need the multi-digit Control Number printed on the Notice, on your proxy card, or in the instructions that accompany your proxy materials, as applicable. Telephone voting is available 24 hours a day and will be accessible until 11:59 p.m. Eastern Time on April 22, 2026. Have your proxy card in hand when you call and then follow the instructions. The telephone voting system has easy to follow instructions and allows you to confirm that the system has properly recorded your vote. If you vote by telephone, you do NOT need to return a proxy card or voting instruction form. If you are an owner in street name, please follow the instructions that accompany your proxy materials.

•

Internet

You can also choose to vote your shares by the Internet. You will need the multi-digit Control Number printed on your Notice, on your proxy card, or in the instructions that accompany your proxy materials, as applicable. The web site for Internet voting is listed on your Notice, proxy card, or in the instructions that accompany your proxy materials. Internet voting is available 24 hours a day and will be accessible until 11:59 p.m. Eastern Time on April 22, 2026. Have your proxy card in hand when you access the web site and follow the instructions to obtain your records and to create an electronic voting instruction form.

If you vote via the Internet, you do NOT need to return a proxy card or voting instruction form.

•

Simply mark your proxy card, date and sign it, and return it in the postage-paid envelope that we included with your materials or return it to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.

•

During the Annual Meeting

You may also vote during the Annual Meeting through our link at www.shareholdermeeting.com/IBKR2026. If your shares are held in the name of a bank, broker or other holder of record, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote at the meeting. All shares that have been properly voted and not revoked will be voted at the Annual Meeting. If you sign and return a proxy card but do not give voting instructions, the shares represented by that proxy card will be voted as recommended by the Board. Returning the proxy card or voting by telephone or via the internet does not deprive you of your right to attend the meeting.

The Internet and telephone voting procedures are designed to authenticate stockholders’ identities, to allow stockholders to give their voting instructions and to confirm that stockholders’ instructions have been recorded properly. We have been advised that the Internet and telephone voting procedures that have been made available to you are consistent with the requirements of applicable law. Stockholders voting by Internet or telephone should understand that, while we and Broadridge do not charge any fees for voting by Internet or telephone, there may nevertheless be costs, such as usage charges from Internet access providers and telephone companies that must be borne by the stockholder.

How can I revoke my proxy or substitute a new proxy or change my vote?

You can revoke your proxy or substitute a new proxy or change your vote before your proxy is voted at the Annual Meeting.

•

You may revoke any proxy that you previously granted or change your vote at any time prior to 11:59 p.m. Eastern Time on April 22, 2026 by entering your new vote electronically via the Internet at www.proxyvote.com using the account, multi-digit Control Number that you previously used or telephonically using the number indicated on your Voting Instruction Form. If you desire to change your vote by mail, you must first request paper copies of the materials and mail your new Voting Instruction Form using the prepaid return envelope provided. However, your new instructions must be received before the close of business on April 22, 2026.

•

You may also revoke your proxy or change your vote at any time prior to the final tallying of votes by:

•

delivering a written notice of revocation to Paul J. Brody, the Secretary of the Company, at Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830;

•

executing and delivering to the Secretary of the Company a later-dated proxy via the internet at www.virtualshareholdermeeting.com/IBKR2026.

How can I obtain an additional proxy card?

If you lose, misplace or otherwise need to obtain a proxy card, and:

•

you are a stockholder of record (see Who is and is not a stockholder of record?), contact Investor Relations at 203-618-4070; or

•

you hold your shares of in street name and, therefore, are not a stockholder of record, contact your bank, broker or account representative.

If I submit a proxy by Internet, telephone or mail, how will my shares be voted?

If you properly submit your proxy by one of these methods, and you do not subsequently revoke your proxy, your shares of common stock will be voted in accordance with your instructions.

If you sign, date and return your proxy card but do not give voting instructions, your shares of common stock will be voted as follows: FOR the election of our director nominees, FOR the ratification of the appointment of Deloitte as our independent registered public accounting firm for our fiscal year ending December 31, 2026, and otherwise in accordance with the judgment of the persons voting the proxy on any other matter properly brought before the Annual Meeting.

Table of Contents

If I hold my shares in “street name” and do not provide voting instructions, can my broker still vote my shares?

Brokerage firms have authority to vote clients’ unvoted shares on some “routine” matters. When a brokerage firm votes its clients’ unvoted shares on routine matters, these shares are counted to determine if a quorum exists to conduct business at the meeting. A brokerage firm cannot vote clients’ unvoted shares on non-routine matters, which results in a broker non-vote. A broker non-vote will be treated as not being entitled to vote on the proposal. For proposals that require a majority of votes voting on the proposal to be approved, a broker non-vote will not be counted for purposes of determining whether the proposal has been approved.

The Company’s proposal to ratify the appointment of our independent public registered accounting firm is considered a routine matter, but the other proposals are not.

What vote is required for a director to be elected or for the other proposals to be ratified?

Election of Directors - You may vote FOR or AGAINST any or all director nominees or you may ABSTAIN as to one or more director nominees. A majority of the votes cast FOR or AGAINST the election of a director nominee must be voted FOR the director nominee in order for the director nominee to be elected. A vote to ABSTAIN is not treated as a vote FOR or AGAINST and thus will have no effect on the outcome of the vote. A director nominee who fails to receive a majority of FOR votes will be required to tender his or her resignation to our Board for consideration.

Ratification of the Appointment of Independent Registered Public Accounting Firm - You may vote FOR or AGAINST the ratification of the appointment of our independent registered public accounting firm or you may ABSTAIN. A majority of the votes cast FOR or AGAINST ratification must be voted FOR ratification for it to pass. A vote to ABSTAIN is not treated as a vote FOR or AGAINST and thus will have no effect on the outcome of the vote.

Advisory Vote on the Compensation of our Named Executive Officers- You may vote FOR or AGAINST the approval of the Company’s executive compensation or you may ABSTAIN. A majority of the votes cast FOR or AGAINST approval must be voted FOR approval for it to pass. A vote to ABSTAIN is not treated as a vote FOR or AGAINST and thus will have no effect on the outcome of the vote. Although the outcome of this advisory vote on the compensation of our named executive officers is non-binding, the Compensation Committee and our Board will review and consider the outcome of this vote when making future compensation decisions for our named executive officers.

Approval to Amend the 2007 Stock Incentive Plan - You may vote FOR or AGAINST the approval of the amendment to the 2007 Stock Incentive Plan or you may ABSTAIN. A majority of the votes cast FOR or AGAINST approval must be voted FOR approval for it to pass. A vote to ABSTAIN is not treated as a vote FOR or AGAINST and thus will have no effect on the outcome of the vote.

Broker Non-Vote - A failure by your broker to vote your shares of common stock when you have not given voting instructions will have no effect on the outcome of the vote on discretionary matters, i.e., the election of directors. A “broker non-vote” occurs when you do not provide the broker with voting instructions on non-discretionary matters and the broker cannot vote your shares on these matters. Because the affirmative vote of a majority of the outstanding shares is necessary to approve each stockholder proposal, a broker non-vote will have the effect of a vote AGAINST that proposal.

How many votes are required to transact business at the Annual Meeting?

A quorum is required to transact business at the Annual Meeting. The presence of Holdings, as the sole holder of the Class B common stock, will constitute a quorum for the transaction of business at the Annual Meeting. Abstentions and broker non-votes are treated as present for quorum purposes.

How do I obtain more information about the Company?

A copy of our 2025 Annual Report is available on the website www.proxyvote.com. You may obtain, free of charge, a copy of our Corporate Governance Guidelines, our Code of Business Conduct and Ethics and the charters for our Audit, Compensation, and Nominating and Corporate Governance Committees by writing to: Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830, Attn: Investor Relations; e-mail: investor relations@interactivebrokers.com. All of these documents are also available on our website at http://investors.interactivebrokers.com.

Who pays for the expenses of this proxy solicitation?

We will pay the expenses of the preparation of proxy materials and the solicitation of proxies for the Annual Meeting. In addition to the solicitation of proxies by mail, solicitation may be made by certain directors, officers or employees of the Company telephonically, electronically or by other means of communication. Our directors, officers and employees will receive no additional compensation for any such solicitation. We will reimburse brokers and other similar institutions for costs incurred by them in mailing proxy materials to beneficial owners in accordance with applicable rules.

CORPORATE GOVERNANCE

Board Leadership Structure

The Board’s current leadership structure separates the positions of Chairman, Chief Executive Officer, and Lead Independent Director. Given the size and ownership structure of the Company as a controlled company, as defined by Nasdaq Stock Market LLC (“Nasdaq”) Rules, we believe that the current leadership structure is suitable for the Company.

The Board’s Role in Risk Oversight

It is management’s responsibility to manage risk and bring to the Board’s attention any material risks to the Company. The Board has oversight responsibility through its Audit Committee which oversees the Company’s risk policies and processes relating to the financial statements and financial reporting processes and the guidelines, policies and processes for mitigating those risks. The Board and executive leadership also provide oversight of risks associated with emerging technologies, including the development and deployment of artificial intelligence systems, cybersecurity threats, and data privacy and protection.

Controlled Company Status

Because of Mr. Thomas Peterffy’s substantial ownership, we are eligible to be and are treated as a “controlled company” for purposes of Nasdaq Rules. As a result, we are not required by Nasdaq to have a majority of independent directors or to maintain compensation and nominating and corporate governance committees composed entirely of independent directors to continue to list shares of common stock on Nasdaq.

Director Independence

Dr. Lawrence Harris serves as Lead Independent Director. The Lead Independent director is responsible for presiding at the executive sessions of the independent directors, calling of meetings of independent directors, serving as liaison between the independent directors and the Chairman, and, if requested by stockholders, ensuring that he is available, when appropriate, for direct communication.

Our Board has determined that each of Dr. Lawrence Harris, Ms. Nicole Yuen, Ms. Jill Bright, Mr. Richard Repetto, and Ms. Lori Conkling are independent under the Nasdaq listing standards and SEC rules.

Family Relationships of Directors and Executive Officers

Other than Mr. William Peterffy, who is the son of Mr. Thomas Peterffy, our Founder and Chairman, none of the current directors or officers, or nominees for director, is related to any other officer or director of the Company or to any nominee for director.

Board and Committee Meetings

Our Board held four meetings during our 2025 fiscal year. Each of our then serving directors attended at least 75% of the meetings of our Board and the committees of our Board on which they served during fiscal year 2025. Our directors are expected to attend annual meetings of stockholders at which they are nominees for election, Board meetings and meetings of the committees on which they serve, and to spend time needed and meet as frequently as necessary to properly discharge their responsibilities. All of our then serving board members attended our virtual 2025 annual meeting of stockholders.

Our Board has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The composition, duties and responsibilities of these committees are set forth below. In the future, our Board may establish other committees, as it deems appropriate, to assist it with its responsibilities. As a controlled company, we are not required by Nasdaq to have a compensation committee or a nominating and corporate governance committee composed entirely of independent directors.

Table of Contents

Audit Committee

Our Audit Committee is comprised of Dr. Lawrence Harris (Chairman), Ms. Nicole Yuen and Mr. Richard Repetto, each of whom is an independent director within the meaning of the rules of Nasdaq and the SEC. Our Audit Committee operates pursuant to a written charter that is available on our website at http://investors.interactivebrokers.com. Dr. Harris is an “audit committee financial expert” as defined in the SEC rules. Each member of our Audit Committee is financially literate. The composition of our Audit Committee satisfies the requirements of the Nasdaq and the SEC.

Our Audit Committee is responsible for, among other things:

•

directly appointing, retaining, evaluating, compensating and terminating our independent registered public accounting firm;

•

discussing with our independent registered public accounting firm auditors their independence from management;

•

pre-approving all audit and permissible non-audit services to be performed by our independent registered public accounting firm;

•

overseeing the financial reporting process and discussing with management and our independent registered public accounting firm the interim and annual financial statements that we file with the SEC; and

•

reviewing and monitoring our accounting principles, policies and financial and accounting controls.

Audit Committee Report

We, the Audit Committee of the Board of Directors of Interactive Brokers Group, Inc., have met and held discussions with management and Interactive Brokers Group, Inc.’s independent registered public accounting firm. As part of this process, we have:

•

reviewed and discussed the audited financial statements with management;

•

discussed with the independent registered public accounting firm the matters required to be discussed by Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 16—Communications with Audit Committee; and

•

received the written disclosures and the letter from the independent registered public accounting firm required by applicable PCAOB requirements for independent accountant communications with audit committees concerning auditor independence.

Based on the review and discussions referred to above, we recommended to the Board of Directors that the audited financial statements be included in Interactive Brokers Group, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, for filing with the SEC.

COMPENSATION MATTERS

Compensation Discussion and Analysis

Compensation Philosophy and Objectives

We adhere to the philosophy that compensation of our named executive officers should first and foremost be directly and materially linked to each executive’s individual performance and our overall performance. The objectives of our executive compensation program are (1) to enhance our long-term value, (2) to assist us in attracting and retaining high quality talent, (3) to reward past performance and motivate future performance, and (4) to align named executive officers’ long-term interests with those of our stockholders.

Role of Executive Officers in Compensation Decisions

Employee performance is reviewed and compensation changes are recommended to the Company’s Chief Executive Officer by members of the IBG LLC Steering Committee. The Chief Executive Officer makes final recommendations to our Compensation Committee, led by our Chairman, which ultimately determines aggregate compensation for all employees and is significantly involved in all key aspects of executive compensation, including the Chairman’s own compensation. Our Compensation Committee is responsible for overseeing the implementation of our philosophy and objectives with respect to the compensation of our named executive officers and directors and administering all aspects of our compensation and benefit plans and programs. The Compensation Committee is currently comprised of Messrs. Thomas Peterffy, Earl H. Nemser and Milan Galik. As a controlled company, we are not required by Nasdaq to have a compensation committee composed entirely of independent directors.

Setting Executive Compensation

Historically, we have kept base salaries for our named executive officers at a relatively modest level in comparison to salaries paid to senior executives at many other companies in our industry and have not sought to “benchmark” salaries to those of our competitors. We have not utilized the services of a compensation consultant to date. We leave decisions as to these matters to our Compensation Committee.

We compensate our named executive officers through three primary methods: base salary, cash bonuses and stock awards. Although the base salaries of our named executive officers are fixed, a substantial additional portion of total compensation is variable. This practice ensures that our executive compensation packages include a combination of base salary and incentives that are appropriate and competitive in the relevant marketplace, as well as related to the individual’s performance and our performance. Our named executive officers have an average of 40 years tenure with us.

Our compensation program is designed to reward performance by tying a substantial portion of each named executive officer’s total potential compensation to individual performance and our performance. We evaluate individual and company performance in a qualitative fashion; we do not utilize specific financial or operating performance goals or targets in setting executive compensation. Through our practice of granting stock awards, the compensation program also promotes and rewards a named executive officer’s tenure and longevity with us, as well as the executive’s role in our financial performance. Stock awards also align the interests of our named executive officers with those of our stockholders.

We do not utilize a set formula for allocating compensation among the elements of total compensation. The subjective decisions regarding the amount and mix of elements which comprise the compensation awarded to our named executive officers are principally based upon an assessment of each executive’s leadership, performance and contribution to the achievement of our financial goals, as well as subjective judgments about each executive individually, rather than on rigid guidelines or formulas. Key factors include the executive’s performance; the nature, scope and level of the executive’s responsibilities; and the executive’s contribution to our overall financial results. Consistent with the overall philosophy described above, the compensation of our named executive officers is predominantly performance based because they have the greatest ability to influence our performance. The decisions concerning specific base compensation elements and the total compensation paid or awarded to our named executive officers in fiscal year 2025 were made within this framework. Specific individual and/or company performance goals or targets were not used. In fiscal year 2025, the aggregate base salaries of our named executive officers constituted approximately 10% of their total aggregate compensation, cash bonuses constituted approximately 24%, stock awards (as described below) constituted approximately 62%, and other compensation constituted the remaining 4%. We granted $20,500,000 worth of stock awards in connection with the Company’s amended 2007 Stock Incentive Plan (“Stock Incentive Plan”), as part of our named executive officers 2025 compensation. The individual allocations of compensation may vary considerably from year to year.

We believe that these practices provide our named executive officers with incentives that are aligned with our conservative risk management policies. A substantial portion of the compensation for our named executive officers is in the form of long-term stock awards, which include vesting periods and conditions. These stock awards are designed not only to encourage long-term performance, but also to minimize the type of short-term risk-taking that might contravene our risk management policies. Our approach to compensation complements our practices of real-time risk assessment and daily measurement of financial performance in the various parts of our businesses, which also act as disincentives to excessive risk-taking.

Elements of Compensation

Although our named executive officers and other key employees holding direct or indirect ownership interests in Holdings have benefited from the increased value of their ownership interests, they have historically received base salary and performance-based cash bonuses and stock awards, and we expect to continue compensating them in this form. We believe that in order to attract and retain highly effective people we must maintain a flexible compensation structure, including base salary, cash bonuses and stock awards. As stated above, we do not utilize a specific formula for allocating compensation among the various elements of total compensation. The amounts of cash bonuses and stock awards were determined at the discretion of our Compensation Committee. Historically, Mr. Thomas Peterffy has received no cash bonus or long-term incentives as the Compensation Committee believes that his and his affiliates’ approximate 91.6% ownership of Holdings which, in turn, owns approximately 73.7% of IBG LLC, has provided sufficient incentive to align his interests with those of our common stockholders.

Base Salary. Base salary is structured to ensure that our named executive officers are fairly and equitably compensated. Base salary is used to appropriately recognize and reward the experience and skills that our employees bring to us and provides motivation for career development and enhancement. Base salary is designed to ensure that all employees continue to receive a basic level of compensation that reflects any acquired skills that are competently demonstrated and are consistently used at work.

Base salary for our named executive officers is initially established based on the scope of their responsibilities and the applicable competitive market compensation paid by other companies for similar positions and is reviewed annually. A single base salary level is established each year, applicable to all named executive officers. Because named executive officers are partially, and sometimes substantially, compensated through performance-based annual cash bonuses and stock awards, and the appreciation in their equity ownership, the base salary is kept at a relatively modest level in comparison to salaries generally believed to be paid to senior executives at many other firms in our industry. A named executive officer’s base salary is not dependent upon our achievement of performance goals.

Bonuses. We maintain an executive cash bonus program to reward superior individual and financial performance for the year. Each year, an executive cash bonus pool is established, from which we pay annual cash bonuses to our named executive officers upon the direction of our Compensation Committee. The amount of the pool is based on several factors, including our financial performance, our progress toward our strategic goals, and the competitive environment for experienced executives. Executive bonuses are based on individual performance and on our financial performance, measured in a qualitative fashion. Specific individual and/or company performance goals or targets have historically not been used. Cash bonuses awarded to our named executive officers in December 2025 for fiscal year 2025 performance ranged from 0% to approximately 678% of the named executive officer’s 2025 base salary, amounting to an aggregate payout of $7,900,000. Our Chairman did not receive a cash bonus, in accordance with historical practices. The annual bonuses paid to our other named executive officers for fiscal year 2025 performance are shown below in the Summary Compensation Table.

Long-Term Incentives. We utilize long-term stock awards to promote the success of each named executive officer, motivate outstanding performance, and encourage and reward employment longevity. Prior to our Initial Public Offering (the “IPO”), executive officers and other key employees historically had been granted equity ownership interests in IBG LLC and continue to hold such interests through their direct or indirect ownership of membership interests in Holdings.

We believe that compensation paid to our named executive officers should be closely aligned with our performance on a continuing and long-term basis and, thereby, with the interests of our stockholders. Toward this end, the Stock Incentive Plan provides for the granting of various types of stock awards. Under the Stock Incentive Plan, we have historically granted stock-based compensation to our named executive officers in the form of restricted stock units that vest and are settled over approximately four years. Other than such restricted stock units, our named executive officers do not hold any outstanding equity awards. Since the inception of the Stock Incentive Plan, it has been our practice to make dividend equivalent payments on unvested stock awards consistent with dividends that are paid with respect to our common stock. Although we retain the flexibility to grant different types of stock awards, it is not currently anticipated that we will grant, as part of executive compensation, stock appreciation rights or other forms of equity-based compensation under the Stock Incentive Plan.

Pursuant to policies set by our Compensation Committee, base salary increases, cash bonuses and stock awards shall be awarded annually, following an evaluation of each named executive officer’s individual performance and the Company’s performance for the year.

Compensation for Named Executive Officers During 2025

Our Compensation Committee determines compensation for all employees, including our named executive officers. Our named executive officers for the 2025 fiscal year were Mr. Thomas Peterffy, our Chairman; Mr. Earl H. Nemser, our Vice Chairman; Mr. Milan Galik, our Chief Executive Officer and President; Mr. Paul J. Brody, our Chief Financial Officer, Treasurer and Secretary; and Dr. Thomas A. Frank, our Executive Vice President.

The Compensation Committee has traditionally set Mr. Peterffy’s compensation as salary only, capped at 0.2% of IBG LLC’s net income. During 2025, Mr. Peterffy was paid a salary of $591,500 by IBG LLC and no bonus or equity awards, in accordance with historical practices. During 2026, Mr. Peterffy will be paid a salary of $610,000 by IBG LLC. We believe that the ownership by Mr. Peterffy and his affiliates, through their direct and indirect ownership in Holdings, of a significant amount of the equity in IBG LLC aligns his interests with those of our common stockholders.

Mr. Earl H. Nemser has historically been compensated for his employment as Vice Chairman, reflecting contributions as legal counsel, as head of the IBG LLC Internal Audit Committee, as a member of the Company’s Steering Committee, in his role at ForecastEx, as a director of many of the Company’s subsidiaries, and, since 2023, as Chairman of Interactive Brokers (U.K.) Limited. The Compensation Committee has made its determination based on the assessments described above under “Setting Executive Compensation.” During 2025, Mr. Nemser was paid a salary of $770,000 by IBG LLC (inclusive of $180,000 of IBG LLC director fees) and a cash bonus of $1,000,000 in accordance with these practices. Mr. Nemser also received a stock award under the Stock Incentive Plan valued at $1,550,000 for the year ended December 31, 2025. During 2026, Mr. Nemser will be paid a salary of $790,000 by IBG LLC (inclusive of $180,000 of IBG LLC director fees).

Messrs. Galik and Brody and Dr. Frank have historically been compensated in accordance with the policies discussed above under “Setting Executive Compensation” with a mixture of base salary, cash bonus, and stock awards under the Stock Incentive Plan. Mr. Galik’s, Mr. Brody’s and Dr. Frank’s 2025 base salary was $590,000. Each received an individual performance-based bonus. In addition to performance evaluations, consideration was given to the benefits derived from each individual’s existing direct or indirect ownership of membership interests in Holdings. Messrs. Galik and Brody and Dr. Frank received stock awards under the Stock Incentive Plan valued at $14,550,000, $3,500,000, and $900,000, respectively, for the year ended December 31, 2025.

The contributions of each of our named executive officers that the Compensation Committee considered included: Mr. Galik has a key role in the management of the Company over the execution of its strategy and in the ongoing development of software and systems for our electronic brokerage platform, driving the growth of the business. The Compensation Committee determined that Mr. Galik’s performance and contribution to the achievement of the Company’s financial goals merited a higher bonus in 2025 than the other named executive officers of the Company. Mr. Brody made ongoing efforts with respect to building and maintaining strong financial and operational controls, a prudent liquidity management program, banking relationships, credit ratings and interaction with domestic and foreign financial regulators. Dr. Frank continued to enhance the Company’s risk management and global technical infrastructure. Their 2026 base salary has been increased to $610,000. Each of Messrs. Galik and Brody and Dr. Frank is expected to receive a stock award under the Stock Incentive Plan in 2026 based on each executive’s anticipated future contribution to our success. The 2025 stock awards under the Stock Incentive Plan were consistent with the above-mentioned policies and reflected the Compensation Committee’s assessment of each executive’s leadership, performance and contribution to the building of our Company.

All salaries and bonuses will be paid by IBG LLC or one of its operating subsidiaries. No employee of IBG LLC will be paid any separate or additional amount for their services as director of the Company, except for director fees. See “Compensation of Directors” below. In addition to the foregoing, certain named executive officers, as a result of their direct and/or indirect ownership of membership interests in Holdings and in IBKR Member Holdings LLC, received indirect distributions from IBG LLC, as described in footnote (5) to the Summary Compensation Table below.

401(k) Plan

We offer substantially all employees of our United States (“U.S.”) based subsidiaries who have met minimum service requirements the opportunity to participate in a defined contribution retirement plan qualifying under the provisions of Section 401(k) of the Internal Revenue Code. The general purpose of this plan is to provide employees with an incentive to make regular savings in order to provide additional financial security during retirement. The plan provides for IBG LLC to match 50% of the employees’ pretax contribution, up to a maximum of 10% of eligible earnings. Employees vest in the matching contribution ratably over six years.

Severance Arrangements

None of our named executive officers have employment agreements and none are subject to severance arrangements. A portion of our named executive officers’ compensation package is in the form of restricted stock units granted under the Stock Incentive Plan. The form of award agreement that we use for granting restricted stock units under the Stock Incentive Plan provides that employees who discontinue employment with us for reasons other than for cause and continue to satisfy certain post-employment requirements and restrictions will be eligible to earn 50% of previously granted but not yet earned stock awards, unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of previously granted but not yet earned stock awards. Such stock awards will continue to vest and be earned upon the vesting schedule set forth in the applicable award agreement. The conditions that must be satisfied in order for such vesting to apply are described below in the section titled “Potential Payments Upon Termination or Change in Control.”

Perquisites

Our named executive officers receive only the fringe benefits normally provided to all other employees, such as health, dental, life, hospitalization, surgical, major medical and disability insurance, participation in our 401(k) plan, paid time off, and other similar company-wide benefits which may be in effect from time to time for all other employees. Other than the standard employee benefits, we do not provide additional perquisites, personal direct or indirect benefits, or use any separate set of standards in determining the benefits for our named executive officers. We believe that our base salary and total compensation package are reasonable and competitive in the industry, and we have demonstrated that we are able to hire and retain talented executives without offering additional perquisites.

Accounting for Stock-Based Compensation

The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718, “Compensation—Stock Compensation” (“ASC Topic 718”), to account for stock awards granted under the Stock Incentive Plan. ASC Topic 718 requires all share-based payments to employees to be recognized in the financial statements using a fair value-based method. Grants, which are denominated in U.S. dollars, are communicated to employees in the year of grant, thereby establishing the fair value of each grant. The fair value of stock awards granted to employees are generally expensed as follows: 50% in the year of grant in recognition of the plans’ post-employment provisions (as described below) and the remaining 50% over the related vesting period utilizing the “graded vesting” method permitted under ASC Topic 718. In the case of “retirement eligible” employees (those employees older than 59 at the time of the grant), 100% of stock awards are expensed when granted.

Stock awards granted under our Stock Incentive Plan are subject to certain post-employment provisions in the event an employee ceases employment with the Company. The form of award agreement used for making grants under the Stock Incentive Plan provides that employees who discontinue employment with the Company (other than for cause) and who continue to satisfy certain post-employment requirements and restrictions will be eligible to earn 50% of previously granted but not yet earned stock awards or, if the employee is over the age of 59, 100% of previously granted but not yet earned stock awards.

We have never issued stock options to our employees.

Potential Payments Upon Termination or Change in Control

As noted elsewhere in this Proxy Statement, we have not entered into any employment, separation or other agreements with our named executive officers that provide for severance payments that would be triggered by a termination of employment. Also, we have not entered into any agreements that provide for payments or accelerated benefits in connection with a change in control.

Table of Contents

Under the form of award agreement that we have used to make grants of restricted stock units under the Stock Incentive Plan, unvested restricted stock units are eligible to continue to vest, in accordance with the terms of the applicable vesting schedule, following a named executive officer’s termination of employment other than for cause, subject to certain conditions. In order for such awards to continue to vest following a termination of employment, the following conditions must be satisfied: (i) the executive provides us with a release of claims, in a form satisfactory to the Company, executed on or before the 60th day following termination of employment; (ii) the executive must provide consulting services for us for up to two hours every calendar quarter that any award remains unvested; (iii) the executive must not directly or indirectly in any domestic or foreign market trade professionally, assist, or provide services, brokerage or facilities to others that directly or indirectly trade, products traded or brokered by us (including, without limitation, products related to options, equities, currencies, debt and indices); (iv) the executive must not engage in any business that competes with any of our lines of business worldwide; (v) the executive must not assist or recommend that others employ, solicit or affiliate with any person who was employed by us in the six months prior to the employment termination; and (vi) the executive must advise us of the details of his or her employment and other information reasonably requested by us from time to time. If a named executive officer has attained age 59 at the time of termination of employment, all of the executive’s outstanding stock awards will be eligible to continue to vest, conditioned upon the satisfaction of the foregoing conditions and if the named executive officer has not attained age 59 at the time of termination of employment, 50% of each outstanding stock award will not vest and the remaining 50% of the stock award will be eligible to continue to vest in accordance with the specified vesting schedule.

Executive Employment Agreements

We have not entered into employment agreements with our named executive officers, and we do not plan on entering into employment agreements at this time. Similarly, we have not entered into, and do not plan on entering into any other agreements that provide for severance benefits upon a termination of employment or payments or benefits in connection with a change in control. Each of our named executive officers have entered into a restrictive covenant agreement that includes non-disclosure, non-competition, and non-solicitation covenants that are applicable following a termination of employment.

Stock Incentive Plan

Under the Stock Incentive Plan up to 160 million shares, on a post-split basis, of common stock may be issued to satisfy vested stock awards granted to directors, officers, employees, contractors and consultants of the Company and its subsidiaries. The purpose of the Stock Incentive Plan is to promote the Company’s long-term financial success by attracting, retaining and rewarding eligible participants.

As a result of the Company’s organizational structure as described in the “Business – Our Organizational Structure” in Part 1, Item1 of our Annual Report on Form 10-K for the year ended December 31, 2025, there is no material dilutive effect upon ownership of common stockholders of issuing shares under the Stock Incentive Plan. The issuances do not materially dilute the book value of the ownership of common stockholders because the stock awards are granted at market value, and upon their vesting and the related issuance of shares of common stock, the ownership of IBG, Inc. in IBG LLC increases proportionately to the shares issued. As a result of such proportionate increase in share ownership, the dilution upon issuance of common stock is borne by IBG LLC’s majority member (i.e., noncontrolling interest), Holdings, and not by IBG, Inc. or its common stockholders. Additionally, dilution of earnings that may take place after issuance of common stock is reflected in the earnings per share (“EPS”) reported in the Company’s financial statements. The EPS dilution can be neither estimated nor projected, but historically it has not been material.

The Stock Incentive Plan is administered by the Compensation Committee. The Compensation Committee has discretionary authority to determine the eligibility to participate in the Stock Incentive Plan and establishes the terms and conditions of the stock awards, including the number of stock awards granted to each participant and all other terms and conditions applicable to such stock awards in individual grant agreements.

Neither the Stock Incentive Plan nor any stock awards granted under the Stock Incentive Plan provide for acceleration upon a change in control. Rather, the Stock Incentive Plan provides that, upon a change in control, the Compensation Committee may, at its discretion, fully vest any granted but not yet earned stock awards under the Stock Incentive Plan, or provide that any such granted but not yet earned awards will be honored or assumed, or new rights substituted by the new employer on a substantially similar basis and on terms and conditions substantially comparable to those of the Stock Incentive Plan.

Table of Contents

We generally grant stock awards on or about December 31 of each year to employees under the Company’s Stock Incentive Plan. We granted 1,876,533 restricted stock units in 2025 under the Stock Incentive Plan.

Under applicable tax law, we are required to withhold an amount based on the value of the shares upon their issuance, and remit the withheld amount to the Internal Revenue Service (“IRS”) and other taxing authorities. To effect that withholding, we may redeem a portion of the shares with an aggregate fair market value equal to the amount of taxes we are required to withhold and remit. For instance, if 1,000 shares would become issuable and we were required to withhold for federal taxes an amount equal to 40% of the value, we would redeem 400 shares and the employee would reclaim 600 shares. The source of funds for the amount to be remitted to the IRS would be a redemption by IBG LLC of a corresponding number of our interests in IBG LLC. Alternatively, we may elect to effect the withholding by facilitating the sale of a portion of the shares, on behalf of employees, in the open market, and the proceeds of such sales would be remitted to the IRS and other taxing authorities.

Stock awards granted under the Stock Incentive Plan are subject to the plan’s post-employment provisions in the event an employee ceases employment with the Company. The form of award agreement that we use for granting restricted stock units under the Stock Incentive Plan provides that employees who discontinue employment with the Company other than for cause and continue to meet the terms of the plans’ post-employment provisions will be eligible to earn 50% of previously granted but not yet earned stock awards, unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of previously granted but not yet earned stock awards. Such stock awards will continue to vest and be earned upon the vesting schedule set forth in the applicable award agreement. The conditions that must be satisfied in order for an employee to achieve such vesting are the same as those applicable to our named executive officers, which requirements are described above in the section titled “Potential Payments Upon Termination or Change in Control.”

Hedging and Pledging of Our Securities

Our directors and employees, including our named executive officers, are prohibited from engaging in a transaction meant to hedge or minimize losses in our common stock, including engaging in transactions in our common stock related derivative products, which include without limitation equity options contracts, security futures contracts and contracts for differences (“CFDs”). Our directors and employees, including our named executive officers, are also prohibited from short selling our common stock and from pledging our common stock as collateral for a loan.

Clawback Policy

Consistent with Section 954 of the Dodd-Frank Act, and SEC and Nasdaq Rules, we have adopted a Clawback Policy, which is applicable to all of our named executive officers and other executive officers. In general, our Clawback Policy requires us to recoup from any executive the amount of “erroneously awarded compensation” in the event that we discover material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. “Erroneously awarded compensation” means, generally, the excess of the amount of performance-based compensation actually received by the executive over the amount of performance-based compensation that the executive would have received had our financial reporting been correct in the first instance. Our Clawback Policy is included as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2025.

In addition to the Clawback Policy, we maintain a Compensation Recoupment Policy which enables us to recoup or cancel certain incentive compensation from officers in certain situations. In general, we may recoup incentive compensation if we become aware of any material wrongdoing on the part of the recipient that had we known about such material wrongdoing at the time the recipient qualified for the grant would have resulted in the relevant grants not being made (or made in a lesser amount) and would provide grounds to terminate the recipient’s employment for cause by reason of (i) a willful material breach of a material p
