Dear Stockholder:

We are pleased to invite you to the WisdomTree Investments, Inc. (“WisdomTree” or the “Company”) 2018 Annual Meeting of Stockholders to be held on June 19, 2018 at 11:00 a.m. Eastern Time. This year’s Annual Meeting will be a completely virtual meeting of stockholders held over the Internet. You will be able to attend the Annual Meeting, vote your shares electronically and submit your questions during the live webcast of the meeting by visiting www.virtualshareholdermeeting.com/wisdomtree18 and entering your 16-digit control number.

Similar to last year, most of our stockholders will not receive paper copies of our proxy materials and will instead receive a Notice of Internet Availability of Proxy Materials with instructions on how to access our proxy materials and how to vote online or by telephone. Such Notice will also provide information on how to obtain paper copies of our proxy materials if a stockholder so requests. This method expedites the receipt of your proxy materials, lowers the costs of our Annual Meeting and helps to conserve our natural resources.

Every stockholder’s vote is important, so whether or not you are planning to attend the meeting, we encourage you to vote your shares by voting (i) over the Internet, (ii) by telephone or (iii) by requesting a paper copy of the proxy materials, including a proxy card, and returning an executed proxy card.

We hope that you will join us at the Annual Meeting live webcast on June 19, 2018. I thank you for your commitment to WisdomTree and urge you to vote your shares.

Sincerely,

Jonathan Steinberg

Chief Executive Officer

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND PROXY MATERIALS

Who is soliciting my vote?

The Board of Directors of WisdomTree Investments, Inc. (“WisdomTree” or the “Company”) is soliciting your vote for the 2018 Annual Meeting of Stockholders.

Who pays for the cost of soliciting proxies?

WisdomTree will pay the cost for the solicitation of proxies by the Board of Directors. Proxies may be solicited personally, by telephone, fax or email by employees of WisdomTree without any remuneration to such individuals other than their regular compensation. WisdomTree also will reimburse brokers, banks, custodians, other nominees and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission (“SEC”), the Company has elected to provide access to its proxy materials via the Internet. Accordingly, the Company is sending a Notice of Internet Availability of Proxy Materials (“Notice”) to its stockholders. All stockholders will be able to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. The Company encourages stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of its annual meetings.

How can I obtain electronic access to the proxy materials?

The Notice will provide you with instructions regarding how to:

The Company’s proxy materials also are available on its investor relations website at http://ir.wisdomtree.com by following the link for “Financial Information.”

Choosing to receive future proxy materials by email will save the Company the cost of printing and mailing documents to you and will reduce the impact of the Company’s annual meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email message next year with instructions containing a link to those materials and a link to the proxy voting website. Your election to receive proxy materials by email will remain in effect until you terminate it.

How do I attend the Annual Meeting and may I ask questions?

The Annual Meeting will be a completely virtual meeting of stockholders held over the Internet. Please go to www.virtualshareholdermeeting.com/wisdomtree18 for instructions on how to attend and participate in the Annual Meeting. Any stockholder may attend and listen live to the webcast of the Annual Meeting over the Internet at such site. Stockholders as of the record date of the Annual Meeting may submit questions while attending the Annual Meeting over the Internet by using the 16-digit control number included in the Notice, proxy card or the voting instructions that accompanied these proxy materials.

What is the difference between a stockholder of record and a beneficial owner of shares held in street name?

Stockholder of record. If your shares are registered directly in your name with the Company’s transfer agent (Continental Stock Transfer & Trust Company), you are considered a “stockholder of record” (or record holder) with respect to those shares, and the Notice was sent directly to you by the Company.

Beneficial owner of shares held in street name. If your shares are held in an account at a brokerage firm, bank, broker-dealer or other similar organization, then you are the “beneficial owner” of shares held in “street name,” and a Notice was forwarded to you by that organization. As a beneficial owner, you have the right to instruct your broker, bank, trustee or nominee how to vote your shares.

How do I vote my shares?

Whether you are a “stockholder of record” or hold your shares in “street name,” you may vote by proxy prior to the polls closing without participating in the online Annual Meeting. To vote by proxy, stockholders have a choice of voting over the Internet, by telephone or by mail using a traditional proxy card. Your shares will be voted in accordance with your instructions. If you plan to attend and participate in the online Annual Meeting, the Company still encourages you to vote prior to the Annual Meeting by Internet, by telephone, or by mail by returning a proxy card following your request of printed materials. This will ensure that your vote will be counted if you are unable to, or later decide not to, participate in the online Annual Meeting. You also may vote online at the Annual Meeting prior to the polls closing. You will need to enter your 16-digit control number (included in your Notice, your proxy card or the voting instructions that accompanied your proxy materials) to vote your shares at the Annual Meeting.

What are the Board’s recommendations on how to vote my shares?

The Board of Directors recommends a vote:

Can I change my vote?

You may revoke your proxy at any time before it is voted by notifying the Secretary of WisdomTree in writing, by returning a signed proxy card with a later date, by transmitting a subsequent vote over the Internet or by telephone prior to the close of the Internet voting facility or the telephone voting facility, or by attending the online meeting, entering your 16-digit control number and voting again electronically at the Annual Meeting.

How many votes can be cast by all stockholders?

153,104,136 shares of the Company’s common stock were outstanding on April 26, 2018 (the record date for determining stockholders eligible to vote) and entitled to be voted at the meeting. Each share of common stock is entitled to one vote on each matter. However, pursuant to Nasdaq Listing Rule 5635 and IM-5635-2 “Interpretative Material Regarding the Use of Share Caps to Comply with Rule 5635,” the shares of the Company’s common stock issued to ETF Securities Limited in the ETFS Acquisition will not be entitled to vote to approve Proposal 3.

What percentage of the vote is required for a proposal to be approved?

Proposal 1: The three nominees for election as Class I directors who receive a plurality of the votes cast for election of directors shall be elected directors.

Proposal 2: A majority of votes cast is necessary for the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018.

Proposal 3: The affirmative vote of a majority of the shares of common stock present in person or by proxy at the Annual Meeting and entitled to vote thereon is required for the approval of the proposal to approve the issuance of shares of common stock upon conversion of the Company’s Series A Non-Voting Convertible Preferred Stock issued in connection with the ETFS Acquisition representing more than 19.99% of the outstanding common stock or voting power of the Company for purposes of complying with Nasdaq Listing Rule 5635.

3

Proposal 4: A majority of votes cast is necessary for the approval of the advisory resolution to approve the compensation of the Company’s named executive officers.

Proposal 5: The vote on the advisory resolution on the frequency of future advisory resolutions to approve the compensation of the Company’s named executive officers will be determined based on a plurality of the votes cast. This means that the option that receives the most votes (every one year, every two years or every three years) will be the option deemed recommended by the stockholders to the Board of Directors.

If there are insufficient votes to approve Proposals 2 or 3, your proxy may be voted by the persons named in the proxy to adjourn the Annual Meeting to solicit additional proxies in favor of the approval of such proposals. If the Annual Meeting is adjourned or postponed for any purpose, at any subsequent reconvening of the meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Annual Meeting unless you withdraw or revoke your proxy. Your proxy may be voted in this manner even though it may have been voted on the same or any other matter at a previous session of the Annual Meeting.

How is a quorum reached?

The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares held of record by stockholders or brokers, bankers or other nominees who do not return a signed and dated proxy or attend the online Annual Meeting in person will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Abstentions and “broker non-votes” (i.e., shares represented at the meeting held by brokers, bankers or other nominees as to which instructions have not been received from the beneficial owners or persons entitled to vote such shares and, with respect to one or more but not all issues, such brokers or nominees do not have discretionary voting power to vote such shares), if any, will be counted for purposes of determining whether a quorum is present for the transaction of business at the meeting.

How is the vote counted?

Votes cast by proxy or in person at the Annual Meeting will be counted by the person(s) appointed by the Company to act as inspector(s) of election for the meeting. The inspector(s) of election will count all votes “for,” “against,” “withhold” and abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Shares represented by proxies that withhold authority to vote for a nominee for election as a director will not be counted as votes “for” a director. Shares properly voted to “abstain” on a particular matter and broker non-votes are treated as having not voted on the particular matter and will therefore not affect the outcome of Proposals 1, 2, 4 and 5. With respect to Proposal 3, abstentions will have the effect of a vote against the proposal, and broker non-votes will have no effect. Due to their advisory nature, the results of the vote on Proposals 4 and 5 are not binding on the Board of Directors or the Compensation Committee.

What does it mean if I receive more than one proxy card or voting instruction form?

It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all your shares are voted.

Could other matters be decided at the Annual Meeting?

WisdomTree does not know of any other matters that may be presented for action at the Annual Meeting. Should any other business come before the meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in their best judgment. If you hold shares through a broker, bank or other nominee as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matters.

4

What happens if the Annual Meeting is postponed?

Your proxy may be voted at the postponed or adjourned meeting. You will be able to change your proxy until it is voted.

Will the Annual Meeting be webcast?

Yes. The Annual Meeting will be a completely virtual meeting and will be webcast live at www.virtualshareholdermeeting.com/wisdomtree18.

What is the deadline to propose actions for consideration or to nominate individuals to serve as directors at the 2019 Annual Meeting?

Stockholders who wish to present proposals for inclusion in our proxy materials for our 2019 Annual Meeting of Stockholders may do so by following the procedures prescribed in Rule 14a-8 under the Securities Exchange Act of 1934 (“Exchange Act”) and in our by-laws. Our Secretary must receive stockholder proposals intended to be included in our proxy statement and form of proxy relating to our 2019 Annual Meeting of Stockholders made under Rule 14a-8 by December 31, 2018. It is the policy of our Nominating Committee to consider nominations for candidates to our Board of Directors that are properly submitted by our stockholders in accordance with our by-laws. Under our current by-laws, proposals of business and nominations for directors other than those to be included in our proxy materials following the procedures described in Rule 14a-8 may be made by any stockholder who was a stockholder of record at the time of the giving of notice provided for in our by-laws, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who complies with the notice procedures set forth in our by-laws (i.e., notice must be timely given and contain the information required by the by-laws). To be timely, a notice with respect to the 2019 Annual Meeting of Stockholders must be delivered to our Secretary no earlier than Tuesday, February 19, 2019 and no later than Thursday, March 21, 2019, unless the date of the 2019 Annual Meeting is advanced by more than thirty (30) days or delayed by more than sixty (60) days from the anniversary date of the 2018 Annual Meeting, in which event the by-laws provide different notice requirements. Any proposal of business or nomination should be mailed to: Gregory Barton, Secretary, WisdomTree Investments, Inc., 245 Park Avenue, 35^th Floor, New York, New York 10167. The Nominating Committee will evaluate candidates for the position of director recommended by stockholders in the same manner as candidates from other sources and will determine whether to interview any candidates or seek any additional information.

Who should I call if I have any additional questions?

If you hold your shares directly, please call Gregory Barton at (212) 801-2080. If your shares are held in street name, please call the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE

Board Composition

Our Board of Directors currently consists of eight members. Our certificate of incorporation and by-laws provide that the number of our directors shall be fixed from time to time by a resolution of a majority of our Board of Directors. Pursuant to our by-laws, the Board of Directors has fixed the number of directors at eight as of the date of this year’s Annual Meeting of Stockholders. In accordance with Delaware law and the Company’s certificate of incorporation and by-laws, the Board of Directors is divided into three staggered classes of directors of the same or nearly the same number. At each annual meeting of the stockholders, a class of directors will be elected for a three-year term to succeed the directors of the same class whose terms are then expiring. The terms of the directors will expire upon the election and qualification of successor directors at the annual meeting of stockholders to be held in 2018 for Class I directors, 2019 for Class II directors and 2020 for Class III directors. The following directors serve in Class I, II and III:

Any directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class shall consist of one third of the Board of Directors. The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent stockholder efforts to effect a change of our management or a change in control.

Pursuant to the corporate governance guidelines adopted by the Board of Directors described below under “Corporate Governance Guidelines,” the Company seeks directors who have high personal and professional integrity, judgment and ability. Our Nominating Committee is responsible for recommending criteria and qualifications for Board membership, identifying and evaluating potential director candidates and recommending to the Board those candidates to be nominated for election to, or fill vacancies on, the Board. The Nominating Committee will seek to identify, and the Board will select, director candidates who satisfy the criteria set forth in the director candidate guidelines included in the Nominating Committee’s charter. Candidates are selected for, among other things, their knowledge, skills, abilities, independence, character, diversity, demonstrated leadership and experience useful to the oversight of our business in the context of the needs of the Board. Our Nominating Committee’s and Board of Directors’ priority in selecting Board members is identification of persons who will further the interests of our stockholders through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among Board members, and professional and personal experiences and expertise relevant to our growth strategy.

Directors

Our Board of Directors is divided into three staggered classes of directors of the same or nearly the same number. At the Annual Meeting, three individuals will be elected to serve as Class I Directors until their term expires in 2021, and until their successors are elected and qualified. During 2017, each of the nominees to the Board served as a Director.

13

primary corporate counsel, from 1991 to 2007, and was employed at that firm beginning in 1982. Mr. Ziemba is a member of the Advisory Board of WFUV FM Radio. Mr. Ziemba received his B.A. in History with university honors from Binghamton University and his J.D., cum laude, from Benjamin N. Cardozo School of Law. Mr. Ziemba served as a director of the Company from 1996 to 2003. Mr. Ziemba is 60 years old.

Jonathan Steinberg, our President and Chief Executive Officer and a member of our Board of Directors, is also an executive officer of the Company. His biographical information is set forth above in the description of the member of our Board of Directors.

Board Meetings

During 2017, the Board of Directors held 11 meetings and did not take any action by unanimous written consent. Each director attended at least 75% of all Board meetings and meetings of the Board committees on which they serve, except for Mr. Steinhardt. Our policy is for all our directors to attend our annual meeting of stockholders. All our directors except Mr. Steinhardt attended our 2017 Annual Meeting of Stockholders.

Board Independence

Nasdaq rules require listed companies to have a board of directors with at least a majority of independent directors. Our Board of Directors has determined that six of our eight directors are independent under the listing standards of the Nasdaq Stock Market. The members determined to be independent are Messrs. Begleiter, Bossone, Neuger, Salerno, Shea and Steinhardt. Under our corporate governance guidelines, directors are required to promptly inform the Lead Independent Director if the director becomes aware of any change in circumstances that may result in such director no longer being considered independent under the Nasdaq rules.

Lead Independent Director

Our Board of Directors believes that it is good corporate practice to designate one of our independent directors as Lead Independent Director. Mr. Salerno has held this designation since the position was established in 2008. The duties of our Lead Independent Director are as follows:

Board Leadership Structure

The Board of Directors has chosen to separate the roles of chairman of the Board of Directors and chief executive officer. Jonathan Steinberg is our President and Chief Executive Officer and Michael Steinhardt is our non-executive Chairman of the Board of Directors. We believe that separating these positions is optimal for WisdomTree because it allows Mr. Steinberg to focus on our day-to-day business, while allowing Mr. Steinhardt to focus on leadership of the Board of Directors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors recognizes the time, effort and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairman, particularly as the Board of Directors’ oversight responsibilities continue to

14

grow. While our by-laws and corporate governance guidelines do not require that our chairman and chief executive officer positions be separate, our Board of Directors believes that having separate positions is the appropriate leadership structure for us and demonstrates our commitment to good corporate governance. Our corporate governance guidelines provide that if the offices of the Chairman of the Board and Chief Executive Officer are combined, the Board will appoint either a non-executive chairman or a Lead Independent Director.

Role of the Board in Risk Oversight

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our operations, strategic direction and intellectual property as more fully discussed under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017, as updated from time to time. Management is responsible for the day-to-day management of the risks we face, while our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The Board of Directors’ role in overseeing the management of our risks is conducted primarily through committees of the Board of Directors, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees. The full Board of Directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on the Company and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairman of the relevant committee reports on the discussion to the full Board of Directors during the committee reports portion of the next board meeting. This enables our Board of Directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Committees of Our Board of Directors

Our Board of Directors has an Audit Committee, a Compensation Committee and a Nominating Committee, each of which operates pursuant to a written charter adopted by our Board of Directors. As provided in its respective charters, each committee reviews its charter at least annually and recommends charter changes to the Board as appropriate. In June 2017, each of the Audit Committee, the Compensation Committee and Nominating Committee reviewed its charter and determined that no amendments were required. Membership on each committee is limited to independent directors as defined under the listing standards of the Nasdaq Stock Market. In addition, members of the Audit Committee also must meet the independence standards for Audit Committee members adopted by the SEC. Our Board of Directors may from time to time establish other committees. Charters for each of the Audit Committee, Compensation Committee and Nominating Committee are available on our investor relations website at http://ir.wisdomtree.com by following the link for “Corporate Governance,” under the heading “Committee Charters.” Our corporate governance guidelines provide that each independent director is expected, but not required, to serve on at least one committee. A director also may serve on more than one committee.

Audit Committee

Messrs. Bossone, Neuger and Salerno currently serve on the Audit Committee, which is chaired by Mr. Salerno. Mr. Lilien served on the Audit Committee until November 2017, when he became an executive officer of the Company and was replaced by Mr. Neuger. During 2017, the Audit Committee held nine meetings and did not take any action by unanimous written consent. Our Board of Directors has determined that each member of the Audit Committee is an “audit committee financial expert,” as defined under the applicable rules of the SEC. The Audit Committee’s responsibilities include:

15

Compensation Committee

Messrs. Bossone, Neuger and Salerno currently serve on the Compensation Committee, which is chaired by Mr. Salerno. Mr. Lilien served on the Compensation Committee until November 2017, when he became an executive officer of the Company and was replaced by Mr. Bossone. During 2017, the Compensation Committee held nine meetings and acted by unanimous consent on two occasions. The Compensation Committee’s responsibilities include:

Nominating Committee

Messrs. Begleiter, Neuger and Steinhardt currently serve on the Nominating Committee, which is chaired by Mr. Steinhardt. Mr. Lilien served on the Nominating Committee until November 2017, when he became an executive officer of the Company. During 2017, the Nominating Committee held three meetings and did not take any action by unanimous written consent. The Nominating Committee’s responsibilities include:

16

Compensation Committee Interlocks and Insider Participation

Messrs. Bossone, Lilien, Neuger and Salerno served as members of the Compensation Committee during 2017. Mr. Lilien resigned from the Compensation Committee in November 2017 when he became an executive officer of the Company and was replaced by Mr. Bossone. None of the members of the Compensation Committee has been an officer of the Company and none were employees of the Company during 2017 and none had any relationship with the Company or any of its subsidiaries during 2017 that would be required to be disclosed as a transaction with a related person.

None of the executive officers of the Company has served on the board of directors or compensation committee of another company (or other board committee performing equivalent functions) at any time during which an executive officer of such other company served on the Company’s Board of Directors or the Compensation Committee.

Corporate Governance Guidelines

The Board of Directors has adopted corporate governance guidelines to promote the effective functioning of the Board of Directors and its committees, and the continued implementation of good corporate governance practices. The corporate governance guidelines address matters including the role and structure of the Board of Directors, the selection, qualifications and continuing education of members of the Board of Directors, board meetings, non-employee director executive sessions, director service on other boards, board committees, management review and succession planning, non-employee director compensation and board and committee evaluations. The corporate governance guidelines are available on our investor relations website at http://ir.wisdomtree.com by following the link for “Corporate Governance,” under the heading “Corporate Governance Guidelines.”

Board and Committee Self-Evaluations

The Board conducts an annual self-evaluation to determine whether it and its committees are functioning effectively. The Board receives comments from all directors and executive officers and reports annually with an assessment of the Board’s performance. The assessment focuses on the Board’s contribution to the Company and specifically focuses on areas in which the Board or management believes that the Board could improve.

Code of Conduct

We have adopted a code of conduct that applies to all our employees, officers and directors, including those officers responsible for financial reporting. Our code of conduct is available on our investor relations website at http://ir.wisdomtree.com by following the link for “Corporate Governance,” under the heading “Code of Conduct.” We intend to disclose any amendments to this code, or any waivers of its requirements, on our website.

Stock Ownership Guidelines

Our Board of Directors has adopted stock ownership guidelines, which require executive officers and non-employee directors to maintain an ongoing ownership position in our common stock while providing them with flexibility in personal financial planning.

On an annual measurement date, which the Board has determined to be November 30^th of each year (“Annual Measurement Date”), the dollar value of the base amount set forth below is converted into the number of shares required to be held to meet the guidelines until the next Annual Measurement Date.

17

Shares of common stock owned by the executive officer or non-employee director directly, jointly or indirectly by a trust, partnership, limited liability company or other entity for the benefit of the executive officer or non-employee director, count toward satisfaction of the guidelines, as well as 50% of unvested restricted stock awards issued under the Company’s equity incentive plans. Stock options (both vested and unvested) do not count toward satisfaction of the guidelines.

If an executive officer or non-employee director does not meet the guidelines on the Annual Measurement Date, he or she will not be permitted to sell or otherwise dispose of the Company’s common stock (except for 50% of restricted stock awards as they vest to cover taxes) until the next Annual Measurement Date, and then only to the extent that his or her remaining holdings do not fall below the applicable requirement. The Compensation Committee has the authority to grant waivers on a case-by-case basis.

As of the last Annual Measurement Date in 2017, all our executive officers and non-employee directors met the guidelines other than Kurt MacAlpine and Win Neuger. Messrs. MacAlpine and Neuger both joined WisdomTree within the last five years. Additional detail regarding ownership of our common stock by our executive officers and non-employee directors is included in this proxy statement under the heading “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters – Stock Ownership Table.”

Policy Regarding Short Sales, Derivatives, Hedging and Pledging

Our insider trading policy applies to all our employees, officers and directors, including our named executive officers. The policy prohibits these individuals from effecting “short sales” of our common stock. These individuals also may not trade in derivatives in our securities (such as put and call options) or engage in any other hedging transaction relating to our securities without prior Audit Committee approval. These individuals are also prohibited from holding shares of our common stock in margin accounts or pledging shares of our common stock as collateral for a loan without prior Audit Committee approval.

EXECUTIVE OFFICER AND DIRECTOR COMPENSATION

Compensation Committee Report

The following report of the Compensation Committee shall not be deemed to be “soliciting material” or to otherwise be considered “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act or the Exchange Act except to the extent that the Company specifically incorporates it by reference into such filing.

The Compensation Committee of the Board of Directors of WisdomTree has reviewed and discussed with management the information contained in the “Compensation Discussion and Analysis” section of this proxy statement for the fiscal year ended December 31, 2017. Based upon that review and discussion, the Compensation Committee has recommended to the Board of Directors that the information set forth below under the heading “Compensation Discussion and Analysis” be included in this proxy statement.

Compensation Committee

Compensation Discussion and Analysis

Overview

This Compensation Discussion and Analysis provides comprehensive information regarding our compensation programs and policies for our CEO, CFO and the next three highest compensated named executive officers (collectively, the “NEOs”) for the year ended December 31, 2017. They are:

We believe we provide a competitive total compensation opportunity for our executive management team through a combination of base salary, cash incentive bonuses, equity compensation and broad-based benefits programs. This Compensation Discussion and Analysis explains the following:

Executive Summary

While our two largest ETFs continued to be out of favor with the market, our executive management team executed on strategic initiatives to diversify and stabilize our asset base by fostering deeper relationships through technology-driven solutions, increasing penetration within existing distribution channels and expanding into new

19

distribution channels, continuing to grow our international business and offering innovative products. These initiatives included:

While from an inflow perspective, we faced challenges, our executive management team remained focused on ensuring WisdomTree is best positioned to take advantage of the growth ahead for the ETF industry. Our

20

compensation program appropriately balances rewarding our employees for both short-term and long-term performance. The Compensation Committee approved a total incentive compensation pool that was 93% of the targeted amount in accordance with our performance-based incentive plan which is discussed further below.

Our Compensation Philosophy and Objectives

Our compensation philosophy and objectives are primarily shaped by strategies targeted to achieve our long-term goals within the business environment in which we operate. We operate in a highly competitive and challenging business environment and we expect competition to continue and intensify. We directly compete with numerous other ETF sponsors and indirectly compete with other larger and multi-national traditional asset management companies. We compete on a number of factors, including the breadth and depth of our product offerings as well as the investment performance and fees of our ETFs. We believe our long-term success depends on our ability to continue to:

The primary objectives of our compensation program are as follows:

The following principles guide our compensation programs:

21

We believe we have designed our competitive compensation packages to incorporate the above principles and ensure that our executive compensation is aligned with corporate strategies and business objectives.

Components of Compensation

We have established the following components of compensation to satisfy our compensation objectives:

We believe these components provide competitive compensation packages recognizing and rewarding individual contributions; ensure that executive compensation is aligned with corporate strategies and business objectives; and promote the achievement of key strategic and operating performance measures.

Base Salary – We use base salary as a means of providing steady pay or a fixed source of compensation for our executive officers, allowing them a degree of certainty to attract and retain them. However, our Compensation Committee believes the majority of our executives’ compensation should be earned through incentive compensation. The base salaries of our executive officers have been at a fixed level over the last several years. In January 2018, the Compensation Committee increased the base salaries for our executive officers to align with median industry pay levels.

Annual Incentive Compensation – Incentive compensation is awarded in cash and is used to motivate and reward our employees for achieving certain short-term operating, financial and other business goals as well as individual performance.

Long-Term Equity Compensation – Because short-term performance does not by itself accurately reflect our overall performance or the return realized by our stockholders, we grant equity awards to our employees as a long-term incentive. We believe that providing equity ownership:

22

In determining the appropriate mix of short-term and long-term incentive compensation to our executives, and all of our employees, our Compensation Committee and management believe that employees with higher authority, responsibility and ability to significantly influence our growth and profitability should receive their incentive compensation more weighted towards long-term equity to align their interest with our long-term success. As a result, incentive compensation paid to our CEO is more heavily weighted to long-term equity incentives, followed by our other executive officers.

Benefits and Perquisites – As stated in our compensation philosophy, our executive officers and Compensation Committee agree that perquisites should be rare and limited to those that are important to our employees’ ability to safely and effectively carry out their responsibilities. Our executive officers are entitled to participate in directors’ and officers’ liability insurance, as well as the various benefits made available to our other employees, such as our group health plans, paid vacation and sick leave, basic life insurance, short- and long-term disability benefits and 401(k) plan with a Company matching contribution of up to 50% of eligible employee contributions.

Severance Benefits – Our NEOs and certain other executive officers are entitled to specified benefits in the event of termination of their employment under certain conditions, including partial acceleration of unvested equity awards and specified severance payments and benefits.

Change in Control Benefits – Our NEOs and certain other executive officers are entitled to specified benefits in the event of termination of their employment within 18 months after a change of control, including partial acceleration of unvested equity awards and cash severance payments and benefits. In addition, if a change of control occurs within 12 months following the executive officer’s involuntary termination without cause or voluntary termination for good reason, all unvested equity awards will vest on the effective date of the change of control. We have provided more detailed information about these benefits, along with estimates of value under various circumstances, in the table below under “Potential Payments Upon Termination or Change in Control.”

Our goal in providing severance and change in control benefits is to offer sufficient certainty in compensation such that our executive officers will focus their full time and attention on the requirements of the business rather than the potential implications for their respective positions. We believe these benefits assist in maintaining a competitive position in terms of attracting and retaining key executives, which is in the best interests of our stockholders.

Role of the Compensation Committee, Performance Evaluations and Management

The Compensation Committee, which is comprised entirely of independent directors, is responsible for the general oversight of our compensation policies and practices. The Compensation Committee also reviews the overall compensation structure and evaluates the overall performance of our executive officers in order to determine that compensation is fair, reasonable, competitive and consistent with our compensation philosophies and objectives based on their collective experiences and business judgment. The Compensation Committee engages an independent compensation consultant with respect to executive compensation.

The Compensation Committee specifically evaluates the performance of our CEO and, with input from our CEO, the overall performance of our other executive officers. The Compensation Committee also discusses the overall performance and compensation of our executives with members of our Board of Directors and presents them with information regarding compensation matters throughout the year as needed.

The Compensation Committee oversees the development, implementation and administration of our compensation programs, including all compensation plans adopted by the Board under which equity grants are

23

made, determines and approves performance measures and goals and objectives relevant to the compensation program. In addition, the Compensation Committee evaluates the performance of the CEO in light of those goals and objectives, determines and approves the CEO’s compensation based on this evaluation, reviews and approves the compensation of the non-CEO executive officers, reviews and approves all discretionary bonuses to our employees, and reviews and approves employment, severance, and change in control agreements as well as any other supplemental benefits provided to our executive officers and other senior employees under the Compensation Committee’s purview. The Compensation Committee also reviews and makes recommendations to our Board of Directors with respect to directors’ compensation. The Compensation Committee also works with our CLO to annually review and reassess the adequacy of its charter, proposing changes as necessary to our Board of Directors for approval.

Our management and executive officers play a critical and important role in setting or recommending compensation levels throughout our organization. Our CEO makes incentive compensation recommendations to the Compensation Committee for the executive officers other than the CEO. In considering the CEO’s recommendations, the Compensation Committee evaluates results measured by the performance measures, goals and objectives of our compensation programs as well as qualitative factors to ensure that compensation is fair, reasonable, competitive and consistent with our compensation philosophies and objectives.

Management works with the Compensation Committee to design and develop compensation programs applicable to all our employees, including recommending changes to existing compensation programs and operational performance targets, preparing analyses of Company financial or operational data or other Compensation Committee briefing materials, analyzing industry data, and, ultimately, implementing the decisions of the Compensation Committee.

Use of Compensation Consultant

The Compensation Committee has retained Frederic W. Cook & Co., a compensation consultant, to provide objective advice on the pay practices, compensation plan design and the competitive landscape for compensation. WisdomTree pays the cost for Frederic W. Cook & Co.’s services. However, the Compensation Committee retains the sole authority to direct, terminate or continue Frederic W. Cook & Co.’s services. The compensation consultant also reviews and makes recommendations for the selection process and pay information used for market compensation benchmarking discussed below. The Compensation Committee has confirmed the independence of Frederic W. Cook & Co. in accordance with SEC and Nasdaq rules and has determined that their work has not raised any conflicts of interest.

Market Compensation Benchmarking

The Compensation Committee monitors relevant market and industry statistics on executive compensation as one of several factors it considers in determining compensation of our executive officers. In making compensation decisions, the Compensation Committee reviews:

Industry surveys – McLagan Partners, Inc., a compensation consulting firm for the financial services industry, prepares annual comprehensive compensation surveys for the asset management industry. These surveys consist of consolidated compensation information of publicly traded and private asset management firms.

Industry peers – Publicly disclosed pay information for certain publicly traded asset management firms that are generally similar in size, market capitalization, product offering or financial metrics as WisdomTree.

The Compensation Committee uses this information for compensation decisions to understand evolving pay trends at asset managers; however, the Compensation Committee recognizes that there are inherent limitations on the comparability and usefulness of the market data, including time lags, differences in scope of responsibilities, geographic differences and other factors. While the Compensation Committee believes such comparative

24

information is useful, such data is intended solely to serve as a reference point to assist the Compensation Committee in its discussions and deliberations.

The Compensation Committee, working with its compensation consultant, reviews the appropriateness of the companies included in the industry peer group twice a year – first, at the beginning of the year, when determining the target pool, and second, at the end of the year, when determining year end compensation. The Compensation Committee will adjust the peer group based on metric changes of the peer group average relative to WisdomTree. Relevant metrics considered by the Compensation Committee include AUM, financial metrics, number of employees and market capitalization. The 2017 peer group is set forth below. There were no changes from the 2016 peer group; however, Calamos Asset Management and CIFC Corp. were removed from the end of the year analysis due to being acquired.

Consideration of Results of Say-on-Pay Vote

Beginning with our 2012 Annual Meeting of Stockholders, and once every three years thereafter, we provide our stockholders with the opportunity to cast an advisory vote on compensation paid to our NEOs, or say-on-pay. At the 2015 Annual Meeting of Stockholders, our say-on-pay proposal received strong support from stockholders, with 97% of our stockholders voting on say-on-pay casting a vote in favor of the proposal. Although the results of the say-on-pay vote are advisory and not binding on the Company, the Board of Directors or the Compensation Committee, the Board and the Compensation Committee value the opinions of our stockholders and the Compensation Committee reviews the outcome of our stockholders’ advisory say-on-pay proposal in its evaluation and determination of executive compensation. The Compensation Committee considered the results of the stockholders’ advisory vote at our 2015 Annual Meeting, and, in light of the strong support for our compensation programs evidenced by our say-on-pay results, decided to maintain our general approach to executive compensation and made no significant changes to our executive compensation program. At this Annual Meeting, we are providing our stockholders with the opportunity to cast an advisory vote on our fiscal year 2017 compensation paid to our NEOs. The Compensation Committee intends to review the outcome of this say-on-pay proposal in its evaluation and determination of executive compensation for fiscal year 2018.

2017 Incentive Compensation Program and Results

The Compensation Committee, together with its independent compensation consultant and management, created a formal performance-based incentive compensation program for 2017. This program was designed to determine the proper level of funding for WisdomTree’s total incentive compensation pool relative to achieving certain quantitative metrics and qualitative results that incentivize growth. The achievement of quantitative metrics determines 50% of the Company’s total incentive compensation pool with the remaining 50% determined at the discretion and judgment of the Compensation Committee based on qualitative results. This split reflects the Compensation Committee’s desire for a more formulaic bonus plan while recognizing the need to apply some level of judgment in setting appropriate compensation levels to reflect the accomplishment of strategic objectives and individual performance.

The quantitative metrics chosen are important operational and financial measurements that our Board of Directors and investors use to measure the health of our business and relative success. Net inflows predominantly measure our ability to increase our AUM through our distribution, marketing, research and product development efforts. Market share of industry flows reflects the relative success of our net inflows as compared to our

25

competitors. Our adjusted pretax margin measures our NEOs’ ability to manage the Company’s financial health and generate earnings for our stockholders. Total shareholder return measures how the Company’s stock performed as compared to other publicly traded asset managers.

The median metrics are formulaic and derived using broad industry data for the asset management industry and ETF industry. As a result, the metrics may increase or decrease year over year. Achieving median metrics generates median compensation; therefore, our compensation plan is designed to reward management for achieving the metrics at a higher rate than the industry average.

Funding for the quantitative performance portion of the pool is between 0% and 200% of the median payout. The Compensation Committee can fund between 0% and 200% of the discretionary portion of the pool but intends in most years to target between 50% and 150% of median.

The payouts and actual results for 2017 are as follows:

Actual quantitative performance was significantly less than median. The discretionary amount was determined by the Compensation Committee using its business judgment, in consultation with its compensation consultant. The Compensation Committee did not allow temporary macro-driven sentiment to alter the Company’s long-term vision and instead focused on significant strategic accomplishments during 2017 including:

These initiatives are described in more detail in the Executive Summary above.

In recommending and determining the amount of incentive compensation and total compensation for our NEOs, our CEO and Compensation Committee primarily used their business judgment and considered:

26

Total Compensation

The table below reflects the total compensation granted in 2017 to our NEOs in a manner that the Compensation Committee used to evaluate total compensation. This table supplements the “2017 Summary Compensation Table” presented below, which is in a different format as required by the SEC:

Long-term equity awards were granted in January 2018 and in the form of restricted stock that will vest in equal annual installments over three years commencing on the first anniversary of the grant date. The values for the long-term equity awards represent the approximate accounting grant date fair values determined in accordance with U.S. generally accepted accounting principles.

R. Jarrett Lilien, our Head of Emerging Technologies, received a one-time sign-on bonus upon joining our Company as an executive officer. The award was comprised of $550,000 in cash and $2,920,000 in restricted stock which vests equally over three years from the date of grant.

27

As stated above in the section entitled “Our Compensation Philosophy and Objectives,” those individuals with greater levels of authority and responsibility have a higher amount of their incentive compensation granted as equity. The following pie charts reflect the elements of total compensation for our NEOs as a percentage of their total compensation based on the chart above:

Risk Analysis of Compensation Policies and Programs

The Compensation Committee has reviewed our overall compensation policies and believes that these policies do not encourage excessive and unnecessary risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on the Company. The design of the compensation policies and programs encourages employees to remain focused on both our short- and long-term goals. For example, while the cash bonus plan measures performance on an annual basis, the equity awards typically vest over a number of years, which we believe encourages employees to focus on sustained stock price appreciation, thus limiting the potential for excessive risk-taking. In addition, we maintain stock ownership guidelines for executive officers and directors as described in this proxy statement under the heading “Stock Ownership Guidelines,” and prohibit hedging, pledging and similar transactions in our common stock by our employees, officers and directors as described in this proxy statement under the heading “Policy Regarding Short Sales, Derivatives, Hedging and Pledging.”

28

Tax and Accounting Considerations

We evaluate the effect of accounting and tax treatment of particular forms of compensation on an ongoing basis and make appropriate modifications to compensation policies where appropriate. In 2014, our Board of Directors and stockholders approved the 2014 Annual Incentive Compensation Plan (“2014 Plan”), which was intended to meet the requirements of Section 162(m) of the Internal Revenue Code of 1986, as amended (“Code”). Prior to the Tax Cuts and Jobs Act (“Tax Act”), which became effective on January 1, 2018, Section 162(m) of the Code generally disallowed a tax deduction to a publicly-traded company for certain compensation in excess of $1,000,000 paid in any taxable year to the chief executive officer and the three other most highly compensated executive officers (other than the chief financial officer). In addition, qualifying performance-based compensation was not subject to the deduction limitation if specified requirements were met. We believe that certain awards made under the 2014 Plan were structured to comply with exemptions in Section 162(m) in place prior to the Tax Act so that certain compensation payable in 2017 under the 2014 Plan is tax-deductible to us. Effective for taxable years beginning after December 31, 2017, the Tax Act (1) expands the scope of Section 162(m) such that all NEOs are “covered employees” and anyone who was a NEO in any year after 2016 will remain a covered employee for as long as he or she (or his or her beneficiaries) receives compensation from the Company and (2) eliminates the exception to the deduction limit for performance-based compensation. Accordingly, compensation paid to our NEOs in excess of $1,000,000 will not be deductible unless it qualifies for the transition relief applicable to certain arrangements in place as of November 2, 2017, as described above.

The Compensation Committee believes that stockholder interests are best served if the Compensation Committee retains maximum flexibility to design executive compensation programs that meet stated business objectives. For these reasons, the Compensation Committee, while considering tax deductibility as a factor in determining executive compensation, may not limit such compensation to those levels that will be deductible, particularly in light of the expansion of the covered employee group and the elimination of the exception for performance-based compensation.

Due to the passage of the Tax Act, the Compensation Committee approved the acceleration of vesting of certain restricted stock awards held by our NEOs. These awards, which were scheduled to vest in January 2018, were accelerated to December 2017 in order for the Company to benefit from a higher tax deduction for these awards in 2017.

Employment Agreements

The compensation paid to our NEOs is governed by employment agreements, which are described in this proxy statement under the heading “Employment Agreements.”

Conclusion

After careful review and analysis, we believe that each element of compensation and the total compensation provided to our executive officers is reasonable and appropriate. The Compensation Committee believes that our compensation program gives our executives appropriate incentive to contribute to our long-term performance and believes that our compensation structure and practices encourage management to work as a team in an entrepreneurial culture for outstanding stockholder returns, without taking unnecessary or excessive risks. We believe the total compensation opportunities of our compensation packages will allow us to attract and retain talented executives who have helped and who will continue to help us grow as we look to the years ahead.

2017 Summary Compensation Table

The following table sets forth certain information with respect to compensation earned during the years indicated below by each NEO.

Summary Compensation Table

CEO Pay Ratio

Our compensation and benefits philosophy and the overall structure of our compensation and benefits programs are broadly similar across the organization to encourage and reward all employees who contribute to

30

our success. We strive to ensure that the pay of our employees reflects the level of their job impact and responsibilities and is competitive within our peer group. Compensation rates are benchmarked and are generally set to be market-competitive in the country in which the jobs are performed. Our ongoing commitment to pay equity is critical to our success in supporting a diverse workforce with opportunities for all employees to grow, develop and contribute.

As required by the SEC, we are providing disclosure about the relationship of the annual total compensation of our median employee to the annual total compensation of our CEO. The SEC rules for identifying the median employee and calculating the pay ratio allow companies to apply various methodologies and assumptions. Therefore, the pay ratio reported by us may not be comparable to the pay ratio reported by other companies. For 2017, the annual total compensation of our median employee, determined in accordance with the amounts presented in the “Total” column of the “2017 Summary Compensation Table,” was $189,392. Our CEO’s annual total compensation, as reported in the Total column of the 2017 Summary Compensation Table, was $3,062,000. Based on this information, the ratio of the annual total compensation of our CEO to the annual total compensation of our median employee is approximately 16 to 1. Our pay ratio estimate has been calculated in a manner consistent with SEC rules using the data and assumptions summarized below.

To identify our median employee, we first determined our employee population as of December 31, 2017, which represented 203 global full-time and part-time employees, excluding our CEO. We then measured the employee population’s total compensation as viewed by our Compensation Committee, which is comprised of base salary, cash incentive compensation and long-term incentive compensation granted for the 2017 performance year. We annualized compensation for any employees who were employed for less than the full year and compensation paid in foreign currencies was converted to U.S. dollars based on a weighted average exchange rate for the relevant period.

Employment Agreements

We have entered into employment agreements with each of the NEOs and certain other executive officers to serve for an indefinite term, and on an “at will” basis. The terms of the employment agreements for each of these executive officers are substantially identical except that for 2017, the annual base salary payable to each executive officer other than Mr. Steinberg was $300,000, with Mr. Steinberg receiving an annual base salary of $450,000. Beginning in 2018, the base salary for each of these executive officers other than Mr. Steinberg was increased to $375,000, and Mr. Steinberg’s base salary was increased to $550,000. Each of these executive officers is eligible to receive such incentive compensation as may be determined by the Company’s Board of Directors or Compensation Committee and to participate in standard Company benefit plans. The employment agreements contain employee confidentiality, assignment of inventions and non-solicitation of employees provisions, as well as non-competition provisions which are applicable as described below. Each of these executive officers also is entitled to the following benefits in the event of the termination of his employment:

Termination by the Company Without Cause or by the Executive Officer for Good Reason. The employment agreements provide that if the executive officer is terminated by the Company other than for “cause” or if the executive officer resigns for “good reason” (each as defined in the employment agreements), the Company will pay the executive officer his base salary through the termination date and the earned but unpaid cash portion of his prior year incentive compensation. In addition, if (i) the executive officer is terminated by the Company other than due to his death or disability, or for “cause” or (ii) the executive officer resigns for “good reason” (each an “Involuntary Termination”) and he (A) enters into and does not revoke a release agreement with the Company and (B) complies with a three-month restrictive covenant from the date of termination, the Company will pay the executive officer:

33

The Termination Year Cash Incentive Compensation will be paid when the Company pays incentive compensation for the termination year to non-terminated senior executives. The Annual Base Salary and Average Cash Incentive Compensation will be paid in substantially equal installments over a 12-month period. The executive officer also may elect to have the Company pay for COBRA insurance coverage for a one-year period following the date of termination.

The employment agreements also provide that any equity award that would have vested in the 12-month period that immediately follows the date of termination will vest immediately upon termination, and unvested awards will remain outstanding for 12 months following the date of termination. In addition, if a “change of control” (as defined in the employment agreements) occurs within 12 months after the date of Involuntary Termination, all equity awards will vest on the effective date of the change of control.

Involuntary Termination Within 18 Months After a Change of Control. In the event of an executive officer’s Involuntary Termination within 18 months after a change of control of the Company, and the executive officer’s (i) entry into and non-revocation of a release agreement with the Company and (ii) compliance with a 12-month restrictive covenant from the date of termination, the Company will pay the executive officer his salary through the termination date and the earned but unpaid cash portion of his prior year incentive compensation plus:

Such amounts will be paid in one lump sum. The executive officer also may elect to have the Company pay for COBRA insurance coverage for a 21-month period following the date of termination. In addition, any equity award that would have vested in the 21-month period that immediately follows the date of termination will vest immediately.

Termination by the Company for Cause or Voluntary Resignation by the Executive Officer Without Good Reason. If the executive officer is terminated by the Company for cause or voluntarily resigns without good reason, the Company may elect to enforce a three-month restrictive covenant in consideration for which the Company will pay the Executive Officer: (i) 25% of the Annual Base Salary; (ii) an amount equal to 12.5% of the average incentive compensation paid to the Executive Officer in the preceding three years; and (iii) an amount equal to 25% of the value of any equity awards that would have vested in the one-year period following the date of termination if no termination had occurred. Such amounts will be paid in substantially equal installments over a three-month period. The executive officer also may elect to have the Company pay for COBRA insurance coverage for a three-month period following the date of termination.

Potential Payments upon Termination or Change in Control

As described above under “Employment Agreements,” our NEOs and certain other executive officers are entitled to payments and benefits in the event of: (i) an Involuntary Termination; (ii) a termination of employment by the Company for cause or voluntary resignation by the executive officer without good reason; and (iii) an Involuntary Termination within 18 months after a change of control. This section is intended to discuss these post-employment payments to our NEOs, assuming the termination from employment occurred on December 31, 2017. Due to the number of factors that affect the nature and amount of any benefits provided

34

upon the occurrence of the events discussed in this section, any actual amounts paid or distributed may be different. Factors that could affect these amounts include the timing during the year of any such event and our stock price.

35

Compensation of Non-Employee Directors

The Compensation terms for the non-employee members of the Board of Directors are as set forth in the following table:

2017 Director Compensation Table

The following table describes compensation paid to our non-employee directors in 2017. All of our directors are reimbursed for out-of-pocket expenses for attending meetings. Directors who are also employees of WisdomTree are not entitled to any compensation for their services as a director.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

Stock Ownership Table

The following table sets forth information regarding the beneficial ownership of shares of our common stock as of the record date (except as otherwise indicated in the footnotes) by (i) each person (including any “group” of persons as that term is used in Section 13d-3 of the Exchange Act) we know to be the beneficial owner of more than 5% of the outstanding shares of our common stock; (ii) each of our executive officers; (iii) each of our directors and director-nominees; and (iv) all of our directors and executive officers as a group.

Beneficial ownership is determined in accordance with Rule 13d-3 under the Exchange Act. Except as otherwise indicated in the footnotes to the following table, we believe, based on the information provided to us, that the persons named in the following table have sole vesting and investment power with respect to the shares they beneficially own, subject to applicable community property laws. Unless otherwise noted, the business address of each of the persons and entities that beneficially own 5% or more of the outstanding shares of common stock is c/o WisdomTree Investments, Inc., 245 Park Avenue, 35^th Floor, New York, NY 10167. We have based our calculation of the percentage of beneficial ownership on 153,104,136 shares of our common stock outstanding as of the record date, including shares of restricted stock issued to our employees but not yet vested.

In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included the shares the person has the right to acquire within 60 days of the date above, including through the exercise of any option, warrant or other right or conversion of any security. The shares that a stockholder has the right to acquire within 60 days, however, are not included in the computation of the percentage ownership of any other stockholder.

37

38

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our executive officers, directors and ten percent stockholders to file reports of ownership and changes in ownership with the SEC. The same persons are required to furnish us with copies of all Section 16(a) forms they file. Based solely on our review of such forms furnished to us during the most recent fiscal year, we believe that all of our executive officers, directors and ten percent stockholders complied with the applicable filing requirements except for (i) Kurt MacAlpine, who filed one Form 4 late to report the surrender of 5,514 shares of common stock upon vesting of restricted stock to cover withholding taxes and (ii) Peter M. Ziemba, who filed one Form 4 late to report a bona fide gift of 5,600 shares of common stock.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Since January 1, 2015, there has not been, nor is there currently proposed, any transaction or series of similar transactions to which we were or are to be a party in which the amount involved exceeded or will exceed $120,000 and in which any of our directors or executive officers or holders of more than 5% or more of any class of our capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or material interest other than the transactions described below.

Stockholders’ Agreement

We are a party to an Amended and Restated Stockholder’s Agreement, dated December 21, 2006, between Michael Steinhardt and Jonathan Steinberg. Under this agreement, Mr. Steinberg agreed to give Mr. Steinhardt a right-of-first refusal to purchase any shares he intends to sell if he were to sell any of his shares in a private transaction.

Related Person Transactions Policy and Procedures

In accordance with its written charter, our Audit Committee conducts an appropriate review of all related party transactions for potential conflict of interest situations on an ongoing basis, and the approval of our Audit Committee is required for all related party transactions. The term “related person transaction” refers to any transaction required to be disclosed by us pursuant to Item 404 of Regulation S-K (or any successor provision) promulgated by the SEC, except that “related party transactions” do not include compensation or employment arrangements that we disclose in our proxy statement (or, if the related person is an executive officer, that we would disclose if such person was a named executive officer).

AUDIT COMMITTEE REPORT

The Audit Committee of the Board of Directors has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2017 and has discussed these statements with management and Ernst & Young LLP, the Company’s independent registered public accounting firm. The Company’s management is responsible for the preparation of the Company’s financial statements and for maintaining an adequate system of disclosure controls and procedures and internal control over financial reporting for that purpose. Ernst & Young LLP is responsible for expressing an opinion on the conformity of the audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. The Audit Committee is responsible for providing independent, objective oversight of the Company’s accounting functions and internal controls.

The Audit Committee also received from, and discussed with, Ernst & Young LLP the written disclosures and other communications required under Public Company Accounting Oversight Board (“PCAOB”) Auditing Standard 1301, Communications with Audit Committees, including among other things, the following:

Ernst & Young LLP also provided the Audit Committee with the written disclosures and the letter required by Rule 3526 of the PCAOB. PCAOB Rule 3526 requires independent registered public accounting firms annually to disclose in writing all relationships that in their professional opinion may reasonably be thought to bear on independence, to confirm their perceived independence and engage in a discussion of independence. The Audit Committee has reviewed this disclosure and has discussed with Ernst & Young LLP their independence from the Company.

Based on its discussions with management and our independent registered public accounting firm, and its review of the representations and information provided by management and our independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 for filing with the Securities and Exchange Commission.

No portion of this Audit Committee Report shall be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), through any general statement incorporating by reference in its entirety the proxy statement in which this Report appears, except to the extent that the Company specifically incorporates this report or a portion of it by reference. In addition, this report shall not be deemed to be “soliciting material” or to be “filed” under either the Securities Act or the Exchange Act.

Proposal 2 requests the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018. Proposal 3 requests approval of the issuance of shares of common stock upon conversion of the Company’s Series A Non-Voting Convertible Preferred Stock issued in connection with the ETFS Acquisition representing more than 19.99% of the outstanding common stock or voting power of the Company for purposes of complying with Nasdaq Listing Rule 5635.

PROPOSAL 1

ELECTION OF DIRECTORS

Nominees

The Nominating Committee recommended, and the Board of Directors nominated

as nominees to stand for re-election as Class I directors for a three-year term until the 2021 Annual Meeting and until his successor is duly elected and qualified.

Unless otherwise instructed, the persons appointed in the accompanying form of proxy will vote the proxies received by them for these nominees, who are all presently directors of WisdomTree. WisdomTree has no reason to believe that any nominee will be unavailable for election at the Annual Meeting. If either of the nominees is unexpectedly not available to serve, proxies may be voted for another person nominated as a substitute by the Board of Directors. The term of office of each person elected as a director will continue until the 2021 annual meeting or until a successor has been elected and qualified, or until the director’s earlier death, resignation or removal.

The section titled “Directors, Executive Officers and Corporate Governance – Directors” commencing on page 7 of this proxy statement contains information about the nominees’ leadership skills and other experiences that caused the Nominating Committee and the Board of Directors to determine that these nominees should serve as directors of WisdomTree.

Vote Required

The affirmative vote of a plurality of the votes cast at the meeting will be required for the election of the Class I director nominees. Broker non-votes and votes withheld will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the election.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION TO THE BOARD OF DIRECTORS OF EACH OF THE ABOVEMENTIONED NOMINEES

44

PROPOSAL 2

RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018. Ernst & Young LLP acted as the Company’s independent registered public accounting firm for the Company for the year ended December 31, 2017. A representative of Ernst & Young LLP is expected to be present at the Annual Meeting with the opportunity to make a statement if he or she desires and to respond to appropriate questions.

The Company’s organizational documents do not require that the stockholders ratify the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm. The Company requests such ratification as a matter of good corporate practice. A majority of the votes properly cast is required for the approval of the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm, and brokers, bankers and other nominees have discretionary voting power on this routine matter. Accordingly, abstentions and broker non-votes will have no effect on the ratification. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether to retain Ernst & Young LLP, but still may retain them. Even if the selection is ratified, the 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.

Principal Accounting Fees and Services

The following table sets forth the fees paid or accrued by us for the audit and other services provided by Ernst & Young LLP during the years ended December 31, 2017 and 2016 (in thousands):

Audit Committee Pre-Approval Policies and Procedures

The Audit Committee pre-approves each audit and non-audit service rendered by Ernst & Young LLP to the Company, including the fees and terms thereof. The Committee may form and delegate authority to subcommittees of the Committee consisting of one or more members when appropriate, including the authority to grant pre-approvals of audit and permitted non-audit services, provided that decisions of such subcommittee to grant pre-approvals shall be presented to the full Committee at its next scheduled meeting pursuant to the Audit Committee Charter. In accordance with this policy, the Audit Committee pre-approved all fees described above before services were rendered.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

PROPOSAL 3

APPROVAL OF THE ISSUANCE OF SHARES OF COMMON STOCK UPON CONVERSION OF THE COMPANY’S SERIES A NON-VOTING CONVERTIBLE PREFERRED STOCK ISSUED IN CONNECTION WITH THE ETFS ACQUISITION REPRESENTING MORE THAN 19.99% OF THE OUTSTANDING COMMON STOCK OR VOTING POWER OF THE COMPANY FOR PURPOSES OF COMPLYING WITH NASDAQ LISTING RULE 5635

The ETFS Acquisition

On November 13, 2017, we and WisdomTree International Holdings Ltd (“WisdomTree International”), one of our indirect wholly owned subsidiaries, entered into a Share Sale Agreement with ETF Securities Limited (“ETF Securities”), as amended by the Waiver and Variation Agreement, dated April 11, 2018 (collectively referred to as the “Share Sale Agreement”), pursuant to which we agreed to acquire ETF Securities’ European exchange-traded commodity, currency and short-and-leveraged business (“ETFS”). On April 11, 2018, we completed the acquisition of ETFS, which we refer to in this proxy statement as the “ETFS Acquisition,” by purchasing the entire issued share capital of a subsidiary of ETF Securities into which ETF Securities transferred ETFS prior to completion of the ETFS Acquisition. ETFS had $17.6 billion of AUM as of April 10, 2018. With the addition of ETFS, our AUM increased to approximately $63.4 billion globally as of April 10, 2018. The ETFS Acquisition elevated WisdomTree to the ninth largest ETP sponsor globally and the largest global independent ETP provider based on AUM, with significant scale and presence in the U.S. and Europe, the two largest ETP markets.

Pursuant to the Share Sale Agreement, we acquired ETFS for a purchase price consisting of (a) $253.0 million in cash, subject to customary adjustments for working capital, and (b) a fixed number of shares of our capital stock, consisting of (i) 15,250,000 shares of common stock (the “Common Shares”) and (ii) 14,750 shares of Series A Non-Voting Convertible Preferred Stock (the “Preferred Shares”), which are convertible into an aggregate of 14,750,000 shares of common stock, subject to certain restrictions as described below.

On April 11, 2018, we also entered into an Investor Rights Agreement with ETF Securities, pursuant to which, among other things, ETF Securities is subject to lock-up, standstill and voting restrictions, and received certain registration rights, each as described below.

The information set forth in this Proposal 3 is qualified in its entirety by reference to the actual terms of the Share Sale Agreement, Certificate of Designations, Investor Rights Agreement and other agreements entered into in connection with the ETFS Acquisition, which are described in, or included as exhibits to, the following reports: (i) our Current Report on Form 8-K, filed with the SEC on November 17, 2018, (ii) our Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on March 1, 2018 and (iii) our Current Report on Form 8-K, filed with the SEC on April 13, 2018.

Senior Secured Debt Financing

On April 11, 2018 and in connection with the ETFS Acquisition, we, WisdomTree International and certain of our subsidiaries party thereto as guarantors entered into a credit agreement (the “Credit Agreement”) with the lenders party thereto and Credit Suisse AG, Cayman Islands Branch, as administrative agent, collateral agent, L/C Issuer and lender. Under the Credit Agreement, the lenders have extended a $200.0 million term loan (the “Term Loan”) to WisdomTree International, the net cash proceeds of which were used by WisdomTree International, together with other cash on hand, to complete the ETFS Acquisition and pay certain related fees, costs and expenses, and made a $50.0 million revolving credit facility (the “Revolver” and, together with the Term Loan, the “Credit Facility”) available to us and WisdomTree International for revolving borrowings from time to time for working capital, capital expenditures and general corporate purposes. Interest on the Term Loan accrues at a rate per annum equal to LIBOR, plus up to 2.00% (commencing at LIBOR, plus 1.75%), and interest on the Revolver accrues at a rate per annum equal to LIBOR, plus up to 1.50% (commencing at LIBOR, plus

46

1.25%), in each case, with the exact interest rate margin determined based on the Total Leverage Ratio (as defined below). The Revolver is also subject to a facility fee equal to a rate per annum of up to 0.50% of the actual daily amount the aggregate commitments (whether used or unused) under the Revolver, with the exact facility fee rate determined based on the Total Leverage Ratio. The Credit Facility matures on April 11, 2021 (the “Maturity Date”). The Term Loan does not amortize and the entire principal balance is due in a single payment on the Maturity Date.

The Credit Agreement includes a financial covenant that requires that we maintain a Total Leverage Ratio, calculated as of the last day of each fiscal quarter commencing with the fiscal quarter ending September 30, 2018, equal to or less than the ratio set forth opposite such fiscal quarter:

“Total Leverage Ratio” means, as of the last day of any fiscal quarter, the ratio of our and our restricted subsidiaries’ Consolidated Total Debt (as defined in the Credit Agreement) as of such date to our and our restricted subsidiaries’ Consolidated EBITDA (as defined in the Credit Agreement) for the four consecutive fiscal quarters ended on such date.

WisdomTree International’s obligations under the Term Loan and the Revolver are unconditionally guaranteed by us and certain of our subsidiaries and secured by a lien on substantially all of our, WisdomTree International’s and such subsidiaries’ present and future property and assets, in each case, subject to customary exceptions and exclusions. Our obligations under the Revolver are unconditionally guaranteed by certain of our wholly-owned domestic subsidiaries and secured by substantially all of our and such subsidiaries’ present and future property and assets, in each case, subject to customary exceptions and exclusions.

The Credit Agreement contains customary affirmative covenants for transactions of this type and other affirmative covenants agreed to by the parties, including, among others, the provision of annual and quarterly financial statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters. The Credit Agreement contains customary negative covenants, including, among others, restrictions on the incurrence of indebtedness, granting of liens, making investments and acquisitions, paying dividends, repurchasing our equity interests, entering into affiliate transactions and asset sales. The Credit Agreement also provides for a number of customary events of default, including, among others, payment, bankruptcy, covenant, representation and warranty, change of control and judgment defaults.

Series A Non-Voting Convertible Preferred Stock

General

On April 10, 2018, we filed a Certificate of Designations of Series A Non-Voting Convertible Preferred Stock with the Secretary of State of the State of Delaware establishing the rights, preferences, privileges, qualifications, restrictions, and limitations relating to the Preferred Shares. The Preferred Shares are intended to provide ETF Securities with economic rights equivalent to our common stock on an as-converted basis. The Preferred Shares have no voting rights, are not transferrable and have the same priority with regard to dividends, distributions and payments as our common stock.

47

Restrictions on Conversion of Preferred Shares

The Preferred Shares are convertible into 14,750,000 shares of our common stock, subject to the following restrictions:

Redemption Rights

ETF Securities has the right to redeem the Preferred Shares under the following circumstances. However, we will not be obligated to make any such redemption payments to the extent such payments would be a breach of any covenant or obligation we owe to any of our secured creditors or is otherwise prohibited by applicable law.

48

Investor Rights Agreement

On April 11, 2018 and in connection with the ETFS Acquisition, we entered into an Investor Rights Agreement with ETF Securities, pursuant to which, among other things:

Reasons for Requesting Stockholder Approval

Our common stock is listed on the Nasdaq Global Select Market, and we are subject to the Nasdaq listing standards set forth in its Listing Rules. Although we are not required under Delaware law to obtain stockholder approval in connection with the ETFS Acquisition, we are required under Listing Rule 5635(a)(1) to obtain stockholder approval to remove the Exchange Cap. This Proposal 3 is not seeking stockholder approval to complete the ETFS Acquisition or to issue the Common Shares or the Preferred Shares to ETF Securities since the ETFS Acquisition has been completed.

Listing Rule 5635(a)(1)

Listing Rule 5635(a)(1) requires stockholder approval prior to the issuance of securities in connection with the acquisition of the stock or assets of another company, where the common stock to be issued (a) has or will have upon issuance voting power of 20% or more of the outstanding voting power prior to the issuance or (b) is or will represent 20% or more of the outstanding common stock prior to the issuance.

Removal of Exchange Cap

Without the Exchange Cap, the maximum number of shares of our common stock issued in connection with the ETFS Acquisition and the number of shares of our common stock issuable upon conversion of the Preferred Shares is 30,000,000, or approximately 21.9% of our pre-issuance shares, based on 136,901,984 shares of our common stock outstanding as of November 13, 2017, the date of the Share Sale Agreement. Excluding the Additional Shares, the maximum number of shares of our common stock issued in connection with the ETFS

49

Acquisition and issuable upon conversion of the Preferred Shares without exceeding the Exchange Cap under Listing Rule 5635(a)(1) is 23,366,707 shares. Accordingly, 6,633,293 shares represent the maximum number of shares of common stock issuable upon conversion of the 6,633 Preferred Shares subject to the Exchange Cap under Listing Rule 5635(a)(1). We therefore seek stockholder approval of this Proposal 3 to satisfy the requirements of Listing Rule 5635(a)(1) and the terms of the Certificate of Designations to permit the issuance of 6,633,293 shares of common stock upon the conversion of the 6,633 Preferred Shares subject to the Exchange Cap.

Effects if Proposal 3 is Approved

Upon approval of this Proposal 3, the Preferred Shares will become convertible in an amount in excess of the Exchange Cap and will no longer be subject to the redemption provisions related to stockholder approval described above. However, under the Certificate of Designations, ETF Securities will remain subject to the additional restriction that, after giving effect to any conversion of Preferred Shares, ETF Securities (together with certain attribution parties) may not beneficially own in excess of 9.99% of the shares of our common stock outstanding. The lock-up and other restrictions applicable to ETF Securities under the Investor Rights Agreement also will remain in place.

Effects if Proposal 3 is Not Approved

If we do not receive approval of this Proposal 3, the Preferred Shares will remain subject to the Exchange Cap and the redemption provisions related to stockholder approval described above unless stockholder approval to remove the Exchange Cap can be obtained at a future special meeting of our stockholders. The efforts to hold one or more special meetings would be costly and time-consuming, and would also divert management’s time and attention away from managing the business.

If our stockholders do not approve this Proposal 3 by December 31, 2018, ETF Securities may require us to redeem the 6,633 Preferred Shares subject to the Exchange Cap at a per share redemption price equal to the dollar volume-weighted average price for a share of common stock for the 30-trading day period ending on December 31, 2018 multiplied by 1,000. Based on the closing price of a share of our common stock as of April 11, 2018, such redemption amount would equal approximately $59.7 million in the aggregate.

Accordingly, the Board believes approval of Proposal 3 will allow us to meet our obligations under the Certificate of Designations and Nasdaq Listing Rule 5635.

Vote Required

A quorum being present, under Nasdaq Listing Rule 5635, the affirmative vote of a majority of the shares of our common stock present in person or by proxy at the Annual Meeting and entitled to vote thereon is required for stockholder approval of the proposal to approve, for purposes of complying with Nasdaq Listing Rule 5635, the issuance of shares of common stock upon conversion of the Preferred Shares issued in connection with the ETFS Acquisition representing more than 19.99% of our outstanding common stock or voting power, without the need for any limitation or cap on issuances. Abstentions will have the effect of a vote AGAINST the proposal. Broker non-votes will have no effect on the proposal.

We hereby notify our stockholders that, pursuant to Nasdaq Listing Rule 5635 and IM-5635-2 “Interpretative Material Regarding the Use of Share Caps to Comply with Rule 5635,” the shares of our common stock issued to ETF Securities in the ETFS Acquisition will not be entitled to vote to approve Proposal 3.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE ISSUANCE OF SHARES OF COMMON STOCK UPON CONVERSION OF THE COMPANY’S SERIES A NON-VOTING CONVERTIBLE PREFERRED STOCK ISSUED IN CONNECTION WITH THE ETFS ACQUISITION REPRESENTING MORE THAN 19.99% OF THE OUTSTANDING COMMON STOCK OR VOTING POWER OF THE COMPANY FOR PURPOSES OF COMPLYING WITH NASDAQ LISTING RULE 5635

PROPOSAL 4

VOTE ON AN ADVISORY RESOLUTION TO APPROVE THE COMPENSATION OF

THE COMPANY’S NAMED EXECUTIVE OFFICERS

The Board of Directors is committed to excellence in governance. As part of that commitment, and as required by Section 14A(a)(1) of the Exchange Act, the Board of Directors is providing the Company’s stockholders with an opportunity to vote on an advisory resolution related to the compensation of the Company’s named executive officers.

As described above under “Executive Compensation – Compensation Discussion and Analysis,” we have developed a compensation policy that is designed to attract and retain key executives responsible for our success and motivate management to enhance long-term stockholder value. We believe our compensation policy strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.

For the reasons discussed above, the Board of Directors unanimously recommends that stockholders vote “FOR” the following resolution:

“RESOLVED, that the Company’s stockholders hereby approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s proxy statement for the 2018 annual meeting of stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other compensation related tables and disclosure.”

As this vote is advisory, it will not be binding upon the Board of Directors or the Compensation Committee and neither the Board of Directors nor the Compensation Committee will be required to take any action as a result of the outcome of this vote. However, the Compensation Committee will carefully consider the outcome of this vote when considering future executive compensation policies.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE

ADVISORY RESOLUTION TO APPROVE THE COMPENSATION OF THE COMPANY’S NAMED

EXECUTIVE OFFICERS

51

PROPOSAL 5

VOTE ON AN ADVISORY RESOLUTION ON THE FREQUENCY OF

FUTURE ADVISORY VOTES TO APPROVE THE COMPENSATION OF THE NAMED EXECUTIVE

OFFICERS

As part of the Board’s commitment to excellence in corporate governance, and as required by the Section 14A(a)(2) of the Exchange Act, the Board of Directors is providing the Company’s stockholders with an opportunity to provide an advisory vote to recommend whether the vote on the advisory resolution on the compensation of the Company’s named executive officers should occur every one, two or three years.

The Board of Directors is not making a recommendation on this matter. Stockholders are not voting to approve or disapprove of this particular recommendation. Instead, the Notice of Internet Availability or proxy card provides for four choices and stockholders are entitled to vote on whether the advisory vote on executive compensation should be held every one, two, or three years, or to abstain from voting.

As this vote is advisory, the results will not be binding upon the Board of Directors and the Board of Directors may decide that it is in the best interest of our stockholders to hold an advisory vote on executive compensation more or less frequently than the frequency receiving the most votes cast by our stockholders. However, the Board of Directors will carefully consider the outcome of this vote when considering the frequency of future advisory votes on executive compensation.
