Dear Stockholder:

You are cordially invited to attend the 2024 Annual Meeting of Stockholders of Interactive Brokers Group, Inc. We will hold the meeting on Thursday, April 18, 2024, at 9:30 a.m. Eastern Time, which you may attend via live webcast at www.virtualshareholdermeeting.com/IBKR2024 by using the multi-digit control number included in your proxy materials. We hope that you will be able to attend.

Details regarding admission to the meeting and the business to be conducted are described in the Notice of Internet Availability of Proxy Materials you received in the mail and in this Proxy Statement. We have also made available a copy of our 2023 Annual Report with this Proxy Statement. We encourage you to read our Annual Report. It includes our audited financial statements and provides information about our business and products.

Securities and Exchange Commission rules allow companies to furnish proxy materials to their stockholders on the Internet. We are pleased to take advantage of these rules and believe that they enable us to provide you with the information you need, while making delivery more efficient and more environmentally friendly. In accordance with these rules, we have sent a Notice of Internet Availability of Proxy Materials to each of our stockholders providing instructions on how to access our proxy materials and 2023 Annual Report over the Internet.

Your vote is very important to us. Whether or not you plan to attend the meeting, your shares should be represented and voted.

Important Notice of Internet Availability of Proxy Materials for the Stockholder Meeting

to be Held on April 18, 2024. This Proxy Statement and our 2023 Annual Report are available

at www.proxyvote.com.

March 6, 2024

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 2024 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 18, 2024 at 9:30 a.m., Eastern Time, and will be held as a virtual meeting at www.virtualshareholdermeeting.com/IBKR2024. 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 8, 2024.

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.

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.

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 20, 2024, the record date for the Annual Meeting. At the close of business on the record date, 107,099,520 shares of common stock were outstanding. In addition, 100 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 shareholders 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 3,139,764 votes, which is equal to the number of membership interests in IBG LLC held on the record date divided by 100. Accordingly, Holdings, as the sole holder of the Class B common stock, is expected to be entitled to cast 313,976,354 votes in the aggregate, or approximately 74.6% of all votes eligible to be cast at the Annual Meeting.

As of March 1, 2024, our directors and named executive officers beneficially owned an aggregate of approximately 3,441,604 shares of common stock and restricted stock unit awards (“stock awards”) that vest within 60 days, constituting approximately 3.21% of the common stock outstanding as of such date. As of the record date, February 20, 2024, our directors and named executive officers owned an aggregate of approximately 3,207,656 shares which can be voted at the Annual Meeting and constituting approximately 0.76% 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 74.6% of all votes eligible to be cast at the Annual Meeting, in favor of the proposals. Accordingly, the voting power of Holdings alone is sufficient to assure the approval of the proposals. See “Beneficial Ownership of Directors, Executive Officers and Owners of More Than Five Percent.”

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.

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 17, 2024. 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.

You may also vote during the Annual Meeting through our link at www.shareholdermeeting.com/IBKR2024. 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.

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

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

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, 2024, and otherwise in accordance with the judgment of the persons voting the proxy on any other matter properly brought before the Annual Meeting.

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.

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 Frequency of the Advisory Vote on Executive Compensation - You may vote your preference for the frequency of an advisory vote on executive compensation. The particular frequency of the advisory vote on the compensation of our named executive officers receiving the greatest number of votes cast FOR such frequency, whether once every year, once every two years, or once every three years, will be the frequency of the advisory vote on the compensation of our named executive officers that stockholders approve for the next six years. A vote to ABSTAIN does not constitute a vote FOR any particular frequency. Although the outcome of this advisory vote on the frequency of the advisory vote on the compensation of our named executive officers is non-binding, our Board will review and consider the outcome of this vote when making determinations as to when we will again submit the advisory vote on the compensation of our named executive officers to stockholders for approval at the annual meeting of stockholders.

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.

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.

A copy of our 2023 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.

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.

The Board’s current leadership structure separates the positions of Chairman and Chief Executive Officer, and Dr. Harris serves as 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.

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.

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.

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, Mr. Philip Uhde, Ms. Nicole Yuen, Ms. Jill Bright and Mr. Richard Repetto is independent under the Nasdaq listing standards and SEC rules.

Other than our Chairman of the ESG Committee, 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.

Our Board held four meetings during our 2023 fiscal year. With the exception of Mr. William Peterffy and Mr. Philip Uhde, 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 2023. 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 2023 annual meeting of stockholders.

Our Board has established an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, and an Environmental, Social and Governance (“ESG”) 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.

Our Audit Committee is comprised of Dr. Lawrence Harris (Chairman), Mr. Philip Uhde and Ms. Nicole Yuen, 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:

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:

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, 2023, for filing with the SEC.

Our ESG Committee is comprised of Mr. William Peterffy (Chairman) and Ms. Jill Bright. Our ESG Committee operates pursuant to a written charter.

Our ESG Committee is responsible for, among other things:

The following table summarizes the membership on each Board committee and the number of committee meetings held during fiscal year 2023.

None of our named executive officers has served as a member of the board of directors or compensation committee of any unrelated entity that has one or more executive officers serving on our Board or Compensation Committee.

The management of IBG LLC and its subsidiaries is governed by a committee comprising our Chairman, our executive officers and certain other members of senior management, which we refer to as the Steering Committee. The Steering Committee handles day-to-day and strategic management issues and is led by our Chief Executive Officer, Mr. Milan Galik.

If you wish to communicate with our Board, independent directors and committees of our Board, you may send your communication in writing to Mr. Paul J. Brody, the Secretary of the Company, at Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830. You must include your name and address in the written communication and indicate whether you are a stockholder of the Company.

The Secretary of the Company will compile all communications, summarize lengthy, repetitive or duplicative communications and forward them to the appropriate director(s) or committee(s) of our Board. The Secretary of the Company will not forward non-substantive communications or communications that pertain to personal grievances, but instead will forward them to the appropriate department within the Company for resolution. If this is the case, the Secretary of the Company will retain a copy of such communication for review by any director or committee upon request.

We have adopted a Code of Business Conduct and Ethics applicable to all directors, officers and employees, including our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer. We will post any amendments to the Code of Business Conduct and Ethics, and any waivers that are required to be disclosed by the rules of either the SEC or Nasdaq on the investor relations section of our website located at www.interactivebrokers.com/ir.

We have adopted an Insider Trading Policies and Procedures that governs the purchase, sale and/or other dispositions of our securities by our directors, officers and employees, as well as their immediate family members and entities owned or controlled by them, that is designed to promote compliance with insider trading laws, rules and regulations. The Insider Trading Policies and Procedures is included as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2023.

Our Board receives periodic updates on cybersecurity matters from the Company’s Chief Executive Officer (based on consultation with the Company’s Chief Information Security Officer and other senior members of the Information Security and/or Technology staff). In addition, a member of senior management responsible for the Company’s Information Security team provides an annual briefing to the Board regarding the overall state of our cybersecurity program, information on the current cybersecurity threat landscape, risks from cybersecurity threats, and any cybersecurity incidents that are reasonably likely to materially affect, or which have materially affected, the Company.

The Company’s management, including through its oversight of Company policies and procedures regarding cybersecurity, is actively involved in the prevention, detection, mitigation, and remediation of cybersecurity incidents impacting the Company. Management’s oversight is augmented through the Company’s Enterprise Risk Management Framework, which includes risk and control assessments related to the Company’s cybersecurity program. Additionally, the Company’s Internal Audit Group periodically audits aspects of the Company’s cybersecurity program and provides reports to the Board’s Audit Committee, and an external audit firm conducts an annual SOC 2 attestation of the Company’s information security controls.

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.

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.

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 38 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 2023 were made within this framework. Specific individual and/or company performance goals or targets were not used. In fiscal year 2023, the aggregate base salaries of our named executive officers constituted approximately 11% of their total aggregate compensation, cash bonuses

constituted approximately 27%, stock awards (as described below) constituted 59%, and other compensation constituted the remaining 3%. We granted $16,675,000 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 2023 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.

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 91.3% ownership of Holdings which, in turn, owns approximately 74.6% 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 2023 for fiscal year 2023 performance ranged from 0% to approximately 630% of the named executive officer’s 2023 base salary, amounting to an aggregate payout of $7,550,000. 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 2023 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.

Our Compensation Committee determines compensation for all employees, including our named executive officers. Our named executive officers for the 2023 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. J. Frank, our Executive Vice President and Chief Information Officer.

The Compensation Committee has traditionally set Mr. Peterffy’s compensation as salary only, capped at 0.2% of IBG LLC’s net income. During 2023, Mr. Peterffy was paid a salary of $550,000 by IBG LLC and no bonus or equity awards, in accordance with historical practices. During 2024, Mr. Peterffy will be paid a salary of $575,000 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’s compensation has historically included lower overall compensation than the other named executive officers, befitting the fact that Mr. Nemser works less than full-time with us. The Compensation Committee has made this determination based on the assessments described above under “Setting Executive Compensation.” During 2023, Mr. Nemser was paid a salary of $730,000 by IBG LLC (inclusive of $180,000 of IBG LLC director fees) and a cash bonus of $900,000 in accordance with these practices. Mr. Nemser also received a stock award under the Stock Incentive Plan valued at $1,200,000 for the year ended December 31, 2023. During 2024, Mr. Nemser will be paid a salary of $755,000 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 2023 base salary was $550,000. 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 $11,000,000, $3,175,000, and $1,225,000, respectively, for the year ended December 31, 2023.

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 2023 than the other executive officers of the Company. Mr. Brody made ongoing efforts with respect to building and maintaining strong financial and operational controls, a prudent liquidity 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 2024 base salary has been increased to $575,000. Each of Messrs. Galik and Brody and Dr. Frank is expected to receive a stock award under the Stock Incentive Plan in 2024 based on each

executive’s anticipated future contribution to our success. The 2023 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.

We offer substantially all employees of our 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.

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.”

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.

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.

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.

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.

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.

Under the Stock Incentive Plan up to 40 million shares 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, 2023, 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.

We generally grant stock awards on or about December 31 of each year to employees under the Company’s Stock Incentive Plan. We granted 1,256,870 restricted stock units in 2023 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.”

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.

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, 2023.

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 provision of the policies of the Company or recipient’s employment contract, or (ii) a willful material violation of applicable law or regulation governing the Company.

The following table summarizes the compensation of our named executive officers for the fiscal years ended December 31, 2023, 2022 and 2021. For purposes of this disclosure, our named executive officers are our Chairman, Vice Chairman, Chief Executive Officer and President, Chief Financial Officer and the other most highly compensated executive officer as determined by their total compensation in the table below.

The following table provides information on stock awards granted to each of our named executive officers, under the Stock Incentive Plan, during the year ended December 31, 2023. This table sets forth information regarding stock awards granted to our named executive officers for performance in 2023.

The following table sets forth outstanding stock awards (unvested restricted stock units) as of December 31, 2023.

The following table contains information about stock awards that vested during the year ended December 31, 2023.

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), we are providing the following information about the relationship of the annual total compensation of our Chief Executive Officer and President, Mr. Milan Galik, and the annual total compensation of our median employee. For the year ended December 31, 2023:

To determine the median of the annual total compensation of all employees of the Company (other than our Chief Executive Officer and President), we identified our total employee population as of December 31, 2023, which consisted of approximately 2,932 individuals, all of which were full-time equivalent employees.

We determined the median based on each employee’s annual total compensation as of December 31, 2023. Annual total compensation consisted of base pay, cash bonuses, the fair value of stock awards granted under the Stock Incentive Plan at the grant date, dividend equivalent payments on unvested stock awards, Company match 401(k) retirement plan contributions, and vacation payout. The annual total compensation of the median employee was calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

As required by Section 953(a) of the Dodd-Frank Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”), as determined under SEC rules, and certain financial performance measures of the Company. Our Compensation Committee did not consider the pay versus performance disclosure when making its incentive compensation decisions. For further information about how we align executive compensation with the Company’s performance, see the Setting Executive Compensation section contained in this Proxy Statement.

 

 

 

The following table contains information regarding 2023 compensation of our non-employee directors with respect to their Board service.

All of our directors are entitled to receive reimbursement of their out-of-pocket expenses in connection with their travel to and attendance at meetings of our Board or committees thereof. Under our current policy, each director is compensated with an annual retainer of $150,000 and an annual grant of stock awards on December 31 valued at $25,000 which vests immediately; in addition, each non-employee director is compensated with a one-time grant of stock awards on December 31 in the year of appointment valued at $75,000 subject to straight-line vesting over a five-year period. The number of stock awards granted is based on the fair market price of our common stock on the date of grant. The chair of a committee of our Board is compensated with an additional annual retainer of $25,000 per committee. We reserve the right to change the manner and amount of compensation to our directors at any time. Stock awards granted under the Stock Incentive Plan to non-employee directors carry the same cancellation provisions as those granted to employees, which are described above.

Holdings currently holds, through its ownership of all of the outstanding shares of our Class B common stock, approximately 74.6% of the combined voting power of the outstanding shares of common stock. While our Class B common stock is owned by Holdings, Mr. Thomas Peterffy, through his indirect ownership of the voting membership interests in Holdings, is able to exercise control over all matters requiring the approval of our stockholders, including the election of our directors and the approval of significant corporate transactions.

The following table sets forth the beneficial ownership of common stock as of March 1, 2024, by each of our directors and named executive officers, by all our directors and named executive officers as a group, and of each beneficial owner, who is not our director or officer, of more than 5% of common stock as of December 31, 2023.

The amounts and percentages of common stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a beneficial owner of a security if that person has or shares voting power, which includes the power to vote or to direct the voting of such security, or investment power, which includes the power to dispose of or to direct the disposition of such security and if that person has the right to acquire such security within 60 days of the filing of this Proxy Statement. Unless otherwise indicated below, each beneficial owner named in the table below has sole voting and sole investment power with respect to all shares beneficially owned. Because none of our named executive officers or directors have the ability to vote shares of our common stock or have the right to receive shares of our common stock within 60 days of March 1, 2024, none of our named executive officers or directors may be deemed to beneficially own shares of our common stock except as set forth below. Mr. Thomas Peterffy may be deemed to own all of the shares of Class B common stock. The following table is based on 107,099,520 shares of common stock and 100 shares of Class B common stock outstanding as of March 1, 2024:

Prior to the IPO, our business had been conducted by subsidiaries of IBG LLC, which was approximately 85% owned by Mr. Thomas Peterffy and his affiliates. In November 2006, the Company was incorporated as a Delaware corporation. Immediately prior to and immediately following the consummation of the IPO, IBG, Inc., Holdings, IBG LLC and the members of IBG LLC consummated a series of transactions collectively referred to herein as the “Recapitalization.” The Recapitalization resulted in the former members of IBG LLC becoming the sole members of Holdings, and established us as the sole managing member of IBG LLC.

As a result of the Recapitalization, immediately following the IPO:

Each share of common stock entitles its holder to one vote per share.

Due to our “Up-C” corporate structure, the Holdings Members maintain their ownership in the Company through 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 do 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 shareholders 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 3,139,764 votes, which is equal to the number of membership interests in IBG LLC held on the record date divided by 100. Accordingly, Holdings, as the sole holder of the Class B common stock, is expected to be entitled to cast 313,976,354 votes in the aggregate.

The Class B common stock currently has approximately 74.6% of the voting power of the Company, which percentage will decrease proportionately over time to the extent that Holdings owns a smaller percentage of IBG LLC. Mr. Thomas Peterffy currently owns all of the voting membership interests in Holdings. Accordingly, Mr. Thomas Peterffy beneficially owns all of the outstanding shares of Class B common stock and is able to exercise control over all matters requiring the approval of our stockholders, including the election of our directors and the approval of significant corporate transactions.

If at any time in the future Mr. Thomas Peterffy and his affiliates own less than a majority of the membership interests in Holdings, then at such time all membership interests in Holdings will become voting membership interests. Accordingly, all members of Holdings, instead of Mr. Thomas Peterffy alone, would together direct the voting of the shares of Class B common stock, and all such members would together exercise control over all matters requiring the approval of our stockholders. However, even if Mr. Thomas Peterffy and his affiliates cease to own a majority of the membership interest in Holdings, Mr. Thomas Peterffy could, depending on his level of percentage ownership, continue to effectively control or significantly influence matters requiring approval of stockholders.

Concurrently with the IPO, IBG, Inc. entered into an exchange agreement with Holdings, IBG LLC and the historical members of IBG LLC (the “Exchange Agreement”). Pursuant to this agreement, the historical members of IBG LLC contributed their IBG LLC membership interests to Holdings and received Holdings membership interests in return. The Exchange Agreement provides for future redemptions of member interests and for the purchase of member interests in IBG LLC by IBG, Inc. from Holdings, which could result in IBG, Inc. acquiring the remaining member interests in IBG LLC that it does not own. The Exchange Agreement, as amended June 6, 2012 and July 23, 2015, provides that the Company may facilitate the redemption by Holdings of interests held by its members through the issuance of shares of common stock through a public offering in exchange for the interests in IBG LLC being redeemed by Holdings. On an annual basis, each holder of a membership interest may request that Holdings redeem the liquefiable portion of that holder’s interest. We expect Holdings to use the net proceeds it receives from such sales to redeem an identical number of Holdings membership interests from the requesting holders. A copy of the First Amendment to the Exchange Agreement was filed as Exhibit 10.1 to the Form 8-K filed by the Company on June 6, 2012 and a copy of the Second Amendment to the Exchange Agreement was filed as Exhibit 10.1 to the Quarterly Report on Form 10-Q for the Quarterly Period Ended September 30, 2015 filed by the Company on November 9, 2015, both of which are incorporated herein by reference. The redemption price for the membership interests in Holdings depends on the timing at which the redemption is made.

A copy of the Exchange Agreement was filed as Exhibit 10.3 to the Quarterly Report on Form 10-Q for the Quarterly Period Ended September 30, 2009 filed by the Company on November 9, 2009 and is incorporated herein by reference.

Sales of common stock and the application of the net proceeds to acquire IBG LLC membership interests are not expected to have a material effect on the existing holders of common stock, as the holders of common stock would then own a larger portion of IBG LLC. Such transactions will have the effect of diluting your percentage ownership in us. However, because we will acquire an increased percentage ownership in IBG LLC over time as a result of such transactions, such transactions will not materially impact your effective percentage ownership of the economics of the underlying IBG LLC business.

Holdings, with the consent of Mr. Thomas Peterffy and our Board, has the right to cause the holders of Holdings membership interests to have all or a portion of their interests redeemed at any time. Such redemptions would be financed in the same manner as the scheduled redemptions described above.

In connection with the IPO, we purchased membership interests in IBG LLC from Holdings for cash. In addition, IBG LLC membership interests held by Holdings may be purchased by us in the future in connection with offerings by us of shares of common stock. Our purchases of IBG LLC membership interests have resulted, and future purchases may result, in increases in the tax basis of the tangible and intangible assets of IBG LLC attributable to our interest in IBG LLC that otherwise would not have been available, although the IRS may

challenge all or part of that tax basis increase or our ability to amortize all or part of that increased tax basis, and a court could sustain such a challenge by the IRS. These increases in tax basis, if sustained, may reduce the amount of taxable income that we are required to recognize as the result of our ownership of membership interests in IBG LLC in the future.

Concurrently with the IPO, we entered into a tax receivable agreement with Holdings that provides for the payment by us to Holdings of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that we actually realize as a result of these increases in tax basis and of certain other tax benefits related to our entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. We will retain 15% of the projected tax benefits.

If either immediately before or immediately after any purchase or the related issuance of our common stock, the Holdings members own or are deemed to own, in the aggregate, more than 20% of our outstanding common stock, then all or part of any increase in the tax basis of goodwill may not be amortizable and, thus, our ability to realize the annual tax savings that otherwise would have resulted if such tax basis were amortizable may be significantly reduced. Although the Holdings members are prohibited under the exchange agreement from purchasing shares of common stock, grants of our common stock to employees and directors who are also members or related to members of Holdings and the application of certain tax attribution rules, such as among family members and partners in a partnership, could result in Holdings members being deemed for tax purposes to own shares of common stock.

In order to mitigate the risk to us of an IRS challenge to the tax basis increase, Holdings and its members will indemnify us for any additional taxes we owe if the IRS or other taxing authorities successfully challenge the basis increase. In addition, if the IRS or other taxing authorities successfully challenge the tax basis increase, any subsequent payments we are required to make under the tax receivable agreement will be reduced accordingly.

For purposes of the tax receivable agreement, cash savings in income and franchise tax will be computed by comparing our actual income and franchise tax liability to the amount of such taxes that we would have been required to pay had there been no increase in the tax basis of the tangible and intangible assets of IBG LLC attributable to our acquisition of our interest in IBG LLC, and had we not entered into the tax receivable agreement. The tax receivable agreement will, unless we exercise our right to terminate the tax receivable agreement for an amount based on an agreed value of payments remaining to be made under the agreement, terminate upon the earlier of (i) the end of the taxable year that includes the 50th anniversary of our initial acquisition of membership interests in IBG LLC, or (ii) the end of the taxable year that includes the 16th anniversary of the date upon which all rights of sale and exchange granted under the exchange agreement have terminated.

Our ability to achieve tax benefits from any increase in the tax basis attributable to our interest in IBG LLC resulting from our acquisition of membership interests in IBG LLC and the payments to be made under the tax receivable agreement with respect thereto depend upon a number of factors, including the law as in effect at the time of a purchase by us of membership interests in IBG LLC or a payment under the tax receivable agreement, the timing of purchases, the fair market value of membership interests in IBG LLC at the time of a purchase, the extent to which such purchases are taxable, the impact of the increase in the tax basis on our ability to use foreign tax credits and the rules relating to the amortization of intangible assets, the composition of IBG LLC’s assets at the time of a purchase, and the amount and timing of our income and of payments under the tax receivable agreement. Depending upon the outcome of these factors, as a result of the size of the increases in the tax basis of the tangible and intangible assets of IBG LLC and its subsidiaries, the payments that we may make to Holdings could be substantial.

We utilize a number of law firms as independent counsel, including Dechert LLP, to which Mr. Earl H. Nemser, our Vice Chairman and one of our directors, serves as an unpaid Independent Advisor. Mr. Nemser served as Special Counsel to Dechert LLP from January 2005 to October 2018.

Our subsidiary, Interactive Brokers LLC (“IB LLC”), may extend credit in the ordinary course of business to certain of our directors, officers, and their affiliates in connection with margin loans. Such loans (i) are made in the ordinary course of business, (ii) are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to IB LLC, and (iii) do not involve more than the normal risk of collectability or present other unfavorable features.

We review all relationships and transactions in which the Company and our directors and executive officers or their immediate family members are participants to determine whether such persons have a direct or indirect material interest. Our Audit Committee, our Chief Executive Officer and our General Counsel are responsible for the development and implementation of processes and controls to obtain information from the directors and executive officers with respect to related person transactions and for then determining, based on the facts and circumstances, whether the Company or a related person has a direct or indirect material interest in the transaction. In addition, our Nominating and Corporate Governance Committee monitors and reviews any issues regarding the “independence” of directors or involving potential conflicts of interest, and evaluates any change of status or circumstance with respect to a director and determines the propriety of the director’s continued service in light of that change.

Our Board presently consists of ten directors. All of our directors are elected annually for a one-year term expiring at the Annual Meeting of Stockholders in the following year. Each director will hold office until his or her successor has been elected and qualified or until the director’s earlier resignation or removal.

In identifying and recommending nominees for positions on our Board, our Nominating and Corporate Governance Committee places emphasis on the following criteria, among others:

Our Nominating and Corporate Governance Committee does not set specific, minimum qualifications that nominees must meet in order for the Committee to recommend them to our Board, but rather believes that each nominee should be evaluated based on his or her individual merits, taking into account the needs of the Company and the composition of our Board. In considering diversity, we consider diversity of viewpoints, backgrounds and experience. We do not, however, have any formal policy with regard to diversity in identifying nominees for a directorship, but rather consider it among the various factors relevant to any particular nominee. Our Nominating and Corporate Governance Committee evaluates possible candidates in detail and suggests individuals to be evaluated in more depth. Once a candidate is identified for serious consideration, the Chairman of our Board enters into a discussion with that candidate.

At the Annual Meeting, our stockholders will be asked to elect the nine director nominees set forth below for a one-year term expiring in 2025. While our Board does not anticipate that any of the director nominees will be unable to stand for election as a director nominee at the Annual Meeting, if that occurs, proxies will be voted in favor of such other person or persons who are recommended by our Nominating and Corporate Governance Committee and designated by our Board.

All the director nominees currently are members of our Board and have been recommended for re-election by our Nominating and Corporate Governance Committee and approved and nominated for re-election by our Board and all the director nominees have consented to serve if elected. Set forth below is information regarding the director nominees, which has been confirmed by each of them for inclusion in this Proxy Statement.

Our Audit Committee has selected Deloitte as our independent registered public accounting firm for our fiscal year ending December 31, 2024. Deloitte has served as our auditor since 1990. We are submitting the selection of independent registered public accounting firm for stockholder ratification at the Annual Meeting.

A representative of Deloitte is expected to be present at the Annual Meeting. He or she will have the opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions from stockholders.

Our organizational documents do not require that our stockholders ratify the selection of Deloitte as our independent registered public accounting firm. We are doing so because we believe it is a matter of good corporate practice. If our stockholders do not ratify the selection, our Audit Committee will reconsider whether to retain Deloitte, but still may retain them. Even if the selection is ratified, our Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

Our Audit Committee is directly responsible for the appointment, termination, compensation and oversight of the Company’s independent registered public accounting firm retained to audit our financial statements. Pursuant to our Audit Committee Charter, our Audit Committee must pre-approve all audit and non-audit services provided by the Company’s independent registered public accounting firm to ensure the services are permissible under SEC and PCAOB independence rules. All audit and non-audit services for which Deloitte was engaged during 2023 were pre-approved by the Audit Committee in compliance with applicable SEC requirements.

The following table summarizes the aggregate fees for professional services provided by Deloitte related to the years ended December 31, 2023 and 2022:

Our Board unanimously recommends a vote FOR ratification of the appointment of Deloitte as our independent registered public accounting firm for our fiscal year ending December 31, 2024. Unless a contrary choice is specified, proxies solicited by our Board will be voted FOR ratification of the appointment.

The Dodd-Frank Act also enables our stockholders to vote, on an advisory or non-binding basis, on how frequently they would like to cast an advisory vote on the compensation of the Company’s named executive officers. By voting on this proposal, stockholders may indicate whether they would prefer an advisory vote on named executive officer compensation once every one, two, or three years, for the next six years.

At our last Annual Meeting we held a vote on the frequency of the advisory vote on executive compensation for our named executive officers, which our stockholders voted for a frequency of every two years. As a result of the Company's desire for more timely input from its stockholders related to executive compensation, the Board has determined that an advisory vote on executive compensation every year is the best approach for the Company at this time.

The Board recommends that stockholders vote in favor of holding an advisory vote on the compensation of our named executive officers at an annual meeting of stockholders every year. In voting on this advisory vote on the frequency of the advisory vote on the compensation of our named executive officers, stockholders should be aware that they are not voting “for” or “against” the Board's recommendation to vote for a frequency of every year for holding future advisory votes on the compensation of our named executive officers. Rather, stockholders will be casting votes to recommend an advisory vote on the compensation of our named executive officers which may be every year, once every two years or once every three years, or they may abstain entirely from voting on the proposal.

The option on the frequency of the advisory vote on the compensation of our named executive officers that receives the most votes from stockholders will be considered by the Board and Compensation Committee as the stockholders' recommendation as to the frequency of future advisory votes on the compensation of our named executive officers. However, the outcome of this advisory vote on the frequency of the advisory vote on the compensation of our named executive officers is not binding on us or our Board. Nevertheless, our Board will review and consider the outcome of this vote when making determinations as to when the advisory vote on the compensation of our named executive officers will again be submitted to stockholders for approval at an annual meeting of stockholders within the next year.

The Board of Directors recommends a vote FOR submitting the advisory vote on the compensation of our named executive officers to stockholders every year.

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership of, and transactions in, our equity securities with the SEC. Such directors, executive officers and stockholders are also required to furnish us with copies of all Section 16(a) reports they file. Purchases and sales of our equity securities by such persons are published on our website at www.interactivebrokers.com.

During 2023, Mr. Earl H. Nemser inadvertently filed one Form 4 late, related to a transfer of shares from EN Holdings LLC, a limited liability company owned by Mr. Nemser and his affiliates, to its members.

At the date hereof, there are no other matters that our Board intends to present, or has reason to believe others will present, at the Annual Meeting. If other matters come before the Annual Meeting, the persons named in the accompanying form of proxy will vote in accordance with their best judgment with respect to such matters.

Stockholders who, in accordance with the SEC’s Rule 14a-8, wish to present proposals for inclusion in the proxy materials to be distributed by us in connection with our 2025 Annual Meeting of Stockholders must submit their proposals to Mr. Paul J. Brody, the Secretary of the Company, at Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830, on or before November 7, 2024. As the rules of the SEC make clear, simply submitting a proposal does not guarantee its inclusion in the proxy materials.

In accordance with our Bylaws, for a matter not included in our proxy materials to be properly brought before the 2025 Annual Meeting of Stockholders, a stockholder’s notice of the matter that the stockholder wishes to present must be delivered to Mr. Paul J. Brody, the Secretary of the Company, at Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830, not less than 120 days prior to the first anniversary of the date of this Proxy Statement. As a result, any notice given by or on behalf of a stockholder pursuant to these provisions of our Bylaws (and not pursuant to the SEC’s Rule 14a-8) must be received no later than November 7, 2024.

Our Nominating and Corporate Governance Committee will consider candidates recommended by stockholders. The policy of our Nominating and Corporate Governance Committee is to consider candidates recommended by stockholders in the same manner as other candidates. See Item 1. Election of Directors for the criteria our Nominating and Corporate Governance Committee utilizes to assess director candidates. Stockholders who wish to submit director candidates for consideration by our Nominating and Corporate Governance Committee for election at our 2025 Annual Meeting of Stockholders may do so by submitting in writing such candidates’ names, credentials, contact information and his or her written consent to be considered as a candidate, in compliance with the procedures required by our Bylaws, to Mr. Paul J. Brody, the Secretary of the Company, at Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830, not less than 120 days prior to the first anniversary of the date of this Proxy Statement. As a result, any notice given by or on behalf of a stockholder pursuant to these provisions of our Bylaws must be received no later than November 7, 2024. The proposing stockholder should also include his or her contact information and a statement of his or her share ownership (how many shares owned and for how long). We do not pay any fees to any third parties for assisting us with nominations and evaluations of candidates for director, nor do we obtain such services from third parties.

In addition, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934 no later than February 17, 2025.

Under SEC rules, a single package of Notices may be sent to any household at which two or more stockholders reside if they appear to be members of the same family. Each stockholder continues to receive a separate Notice within the package. This procedure, referred to as “householding,” reduces the volume of duplicative information stockholders receive and reduces mailing expenses. Stockholders may revoke their consent to future householding mailings by contacting our Investor Relations Department at 2 Pickwick Plaza, Greenwich, Connecticut 06830, Attn: Investor Relations, telephone: 203-618-4070, e-mail: investor-relations@interactivebrokers.com.
