Dear Stockholder:

        You are invited to attend the Annual Meeting of Stockholders of IAC/InterActiveCorp, which will be held on Wednesday, June 21, 2017, at 9:00 a.m., local time. This year's Annual Meeting will be a completely virtual meeting, conducted solely online. Stockholders will be able to attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/IACI2017. We believe hosting a virtual meeting will allow for greater stockholder attendance at the Annual Meeting by enabling stockholders that might not otherwise be able to travel to a physical meeting to attend online and participate from any location around the world.

        At the Annual Meeting, stockholders will be asked to: (1) elect twelve directors, (2) vote on two advisory proposals regarding executive compensation and (3) ratify the appointment of Ernst & Young as IAC's independent registered public accounting firm for the 2017 fiscal year. IAC's Board of Directors believes that the proposals being submitted for stockholder approval are in the best interests of IAC and its stockholders and recommends a vote consistent with the Board's recommendation for each proposal.

        It is important that your shares be represented and voted at the Annual Meeting regardless of the size of your holdings. Whether or not you plan to participate in the Annual Meeting online, please take the time to vote online, by telephone or, if you receive a printed proxy card, by returning a marked, signed and dated proxy card. If you participate in the Annual Meeting online, you may also vote your shares online at that time if you wish, even if you have previously submitted your vote.

Sincerely,

Barry Diller
Chairman and Senior Executive

PROXY STATEMENT
QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

Q:

Why did I receive a Notice of Internet Availability of Proxy Materials?

A:

In accordance with rules adopted by the U.S. Securities and Exchange Commission (the "SEC"), we once again have elected to deliver this proxy statement and our 2016 Annual Report on Form 10-K to the majority of our stockholders online in lieu of mailing printed copies of these materials to each of our stockholders (the "Notice Process"). If you received a Notice of Internet Availability of Proxy Materials (the "Notice") by mail, you will not receive printed copies of our proxy materials unless you request them. Instead, the Notice provides instructions on how to access this proxy statement and our 2016 Annual Report on Form 10-K online, as well as how to obtain printed copies of these materials by mail. We believe that the Notice Process allows us to provide our stockholders with the information they need in a more timely manner than if we had elected to mail printed materials, while reducing the environmental impact of, and lowering the costs associated with, the printing and distribution of our proxy materials.

The Notice, our proxy materials and our 2016 Annual Report on Form 10-K are being mailed on or about May 10, 2017 to stockholders of record at the close of business on April 27, 2017 and this proxy statement and our 2016 Annual Report on Form 10-K will be available at www.proxyvote.com beginning on May 10, 2017. If you received a Notice by mail but would rather receive printed copies of our proxy materials, please follow the instructions included in the Notice. You will not receive a Notice if you have previously elected to receive printed copies of our proxy materials.

Q:

Can I vote my shares by filling out and returning the Notice?

A:

No. However, the Notice provides instructions on how to vote your shares before the date of the Annual Meeting by way of completing and submitting your proxy online, by phone or by requesting and returning a written proxy card by mail, or by voting at the Annual Meeting online at www.virtualshareholdermeeting.com/IACI2017.

Q:

How do I attend and participate in the Annual Meeting?

A:

To participate in the Annual Meeting, go to www.virtualshareholdermeeting.com/IACI2017 and enter the 16-digit control number included on your Notice, your proxy card or the instructions that accompanied your proxy materials.

Q:

Who is entitled to vote at the Annual Meeting?

A:

Holders of IAC common stock and Class B common stock at the close of business on April 27, 2017, the record date for the Annual Meeting established by IAC's Board of Directors, are entitled to receive notice of the Annual Meeting and to vote their shares at the Annual Meeting and any related adjournments or postponements.

At the close of business on April 27, 2017, there were 72,963,884 shares of IAC common stock and 5,789,499 shares of Class B common stock outstanding and entitled to vote. Holders of IAC common stock are entitled to one vote per share and holders of Class B common stock are entitled to ten votes per share.

Q:

What is the difference between a stockholder of record and a stockholder who holds stock in street name?

A:

If your IAC shares are registered in your name, you are a stockholder of record. If your IAC shares are held in the name of your broker, bank or other holder of record, your shares are held in street name.

1

You may examine a list of the stockholders of record at the close of business on April 27, 2017 for any purpose germane to the Annual Meeting during normal business hours during the 10-day period preceding the date of the meeting at IAC's corporate headquarters, located at 555 West 18th Street, New York, New York 10011.

Q:

What shares are included on the enclosed proxy card?

A:

If you are a stockholder of record only, you will receive one proxy card from Broadridge for all IAC shares that you hold directly. If you hold IAC shares in street name through one or more banks, brokers and/or other holders of record, you will receive proxy materials, together with voting instructions and information regarding the consolidation of your votes, from the third party or parties through which you hold your IAC shares. If you are a stockholder of record and hold additional IAC shares in street name, you will receive proxy materials from Broadridge and the third party or parties through which your IAC shares are held.

Q:

What are the quorum requirements for the Annual Meeting?

A:

The presence at the Annual Meeting, in person or by proxy, of holders having a majority of the total votes entitled to be cast by holders of IAC common stock and Class B common stock at the Annual Meeting constitutes a quorum. Stockholders who participate in the Annual Meeting online at www.virtualshareholdermeeting.com/IACI2017 will be considered to be attending such meeting in person for purposes of determining whether a quorum has been met. When the holders of IAC common stock vote as a separate class, the presence at the Annual Meeting of holders of a majority of the total votes entitled to be cast by holders of IAC common stock is required for a quorum to be met. Shares of IAC common stock and Class B common stock represented by proxy will be treated as present at the Annual Meeting for purposes of determining whether there is a quorum, without regard to whether the proxy is marked as casting a vote or abstaining.

Q:

What matters will IAC stockholders vote on at the Annual Meeting?

A:

IAC stockholders will vote on the following proposals:

•

Proposal 1—to elect twelve members of IAC's Board of Directors, each to hold office for a one-year term ending on the date of the next succeeding annual meeting of stockholders or until such director's successor shall have been duly elected and qualified (or, if earlier, such director's removal or resignation from IAC's Board of Directors);

•

Proposal 2—to hold an advisory vote on executive compensation (the "say on pay vote");

•

Proposal 3—to hold an advisory vote on the frequency of holding the say on pay vote in the future;

•

Proposal 4—to ratify the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for the 2017 fiscal year; and

•

to transact such other business as may properly come before the Annual Meeting and any related adjournments or postponements.

Q:

What are my voting choices when voting for director nominees and what votes are required to elect director nominees to IAC's Board of Directors?

A:

You may vote in favor of all director nominees, withhold votes as to all director nominees or vote in favor of and withhold votes as to specific director nominees.

The election of each of Edgar Bronfman, Jr., Chelsea Clinton, Barry Diller, Michael D. Eisner, Bonnie S. Hammer, Victor A. Kaufman, Joseph Levin, David Rosenblatt and Alexander von

2

Furstenberg as directors requires the affirmative vote of a plurality of the total number of votes cast by the holders of shares of IAC common stock and Class B common stock voting together as a single class (hereinafter referred to as IAC capital stock), with each share of common stock and Class B common stock representing the right to one and ten vote(s), respectively.

The election of each of Bryan Lourd, Alan G. Spoon and Richard F. Zannino as directors requires the affirmative vote of a plurality of the total number of votes cast by the holders of shares of IAC common stock voting as a separate class.

The Board recommends that our stockholders vote FOR the election of each of the director nominees.

Q:

What are my voting choices when voting on the advisory say on pay proposal and what votes are required to approve the proposal?

A:

You may vote in favor of the advisory proposal, vote against the advisory proposal or abstain from voting on the advisory proposal.

The approval, on an advisory basis, of the say on pay proposal requires the affirmative vote of the holders of a majority of the voting power of shares of IAC capital stock present at the Annual Meeting in person or represented by proxy and voting together. As an advisory vote, the outcome is not binding upon the Company.

The Board recommends a vote FOR the advisory vote on executive compensation.

Q:

What are my voting choices when voting on the advisory proposal on the frequency of holding the say on pay vote and what votes are required to approve the frequency of holding the say on pay vote?

A:

You may vote in favor of holding the say on pay vote every year, every two years or every three years or abstain from voting on this advisory proposal.

The approval, on an advisory basis, of the frequency of holding the say on pay vote in the future requires the affirmative vote of the holders of a majority of the voting power of shares of IAC capital stock present at the Annual Meeting in person or represented by proxy and voting together. However, if no choice receives a majority of votes, then the option that receives the highest number of votes cast by stockholders will be considered by the Board as the stockholders' recommendation as to the frequency of holding future say on pay votes.

As an advisory vote, the votes cast in connection with this proposal are not binding upon the Company. While the Board is making a recommendation with respect to this proposal, IAC stockholders are being asked to vote for one of the choices specified above, and not whether they agree or disagree with the Board's recommendation.

The Board recommends a vote for holding the say on pay vote once EVERY THREE YEARS at IAC's Annual Meeting of Stockholders.

Q:

What are my voting choices when voting on the ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for the 2017 fiscal year and what votes are required to ratify such appointment?

A:

You may vote in favor of the ratification, vote against the ratification or abstain from voting on the ratification.

The ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for the 2017 fiscal year requires the affirmative vote of the holders of a majority of

3

the voting power of shares of IAC capital stock present at the Annual Meeting in person or represented by proxy and voting together.

The Board recommends that our stockholders vote FOR the ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for the 2017 fiscal year.

Q:

Could other matters be decided at the Annual Meeting?

A:

As of the date of this proxy statement, the Company did not know of any matters to be raised at the Annual Meeting, other than those referred to in this proxy statement.

If any other matters are properly presented at the Annual Meeting for consideration, the three IAC officers who have been designated as proxies for the Annual Meeting (Joanne Hawkins, Glenn H. Schiffman and Gregg Winiarski) will have the discretion to vote on those matters for stockholders who have submitted their proxy.

Q:

What do I need to do now to vote at the Annual Meeting?

A:

IAC's Board of Directors is soliciting proxies for use at the Annual Meeting. Stockholders may submit proxies to instruct the designated proxies to vote their shares before the date of the Annual Meeting in any of three ways:

•

Submitting a proxy online:  Submit your proxy online. The website for online proxy voting is www.proxyvote.com. Online proxy voting is available 24 hours a day and will close at 11:59 p.m., Eastern Standard Time, on Tuesday, June 20, 2017;

•

Submitting a proxy by telephone:  Submit your proxy by telephone by using the toll-free telephone number provided on your proxy card (1.800.690.6903). Telephone proxy voting is available 24 hours a day and will close at 11:59 p.m., Eastern Standard Time, on Tuesday, June 20, 2017; or

•

Submitting a proxy by mail:  If you choose to submit your proxy by mail, simply mark your proxy, date and sign it, and return it in the postage-paid envelope provided or to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, New York 11717.

You may also participate in the Annual Meeting online at www.virtualshareholdermeeting.com/IACI2017 and vote your shares online at that time, even if you have previously submitted your vote. To do so, you will need the 16-digit control number included on your Notice, your proxy card or the instructions that accompanied your proxy materials.

For IAC shares held in street name, holders may submit a proxy online or by telephone before the date of the Annual Meeting if their broker, bank or other holder of record makes these methods available. If you submit a proxy online or by telephone, DO NOT request and return a printed proxy card from IAC or from your broker, bank or other holder of record. If you hold your shares through a broker, bank or other holder of record, follow the voting instructions you receive from your broker, bank or other holder of record.

Q:

If I hold my IAC shares in street name, will my broker, bank or other holder of record vote these shares for me?

A:

If you hold shares of IAC common stock in street name, you must provide your broker, bank or other nominee with instructions in order to vote these shares. If you do not provide voting instructions, whether your shares can be voted by your broker, bank or other holder of record depends on the type of item being considered for a vote.

4

Non-Discretionary Items.    The election of directors and the two advisory proposals related to executive compensation are non-discretionary items and may NOT be voted on by your broker, bank or other holder of record absent specific voting instructions from you. If your bank, broker or other holder of record does not receive specific voting instructions from you, a "broker non-vote" will occur in the case of your shares of IAC common stock for this proposal.

Discretionary Items.    The ratification of Ernst & Young LLP as IAC's independent registered public accounting firm for the 2017 fiscal year is a discretionary item. Generally, brokers, banks and other holders of record that do not receive voting instructions may vote on this proposal in their discretion.

Q:

What effect do abstentions and broker non-votes have on quorum requirements and the voting results for each proposal to be voted on at the Annual Meeting?

A:

Abstentions and broker non-votes are counted as present for purposes of determining a quorum. Abstentions are treated as shares present and entitled to vote and, as a result, have the same effect as a vote against any proposal for which the voting standard is based on the number of shares present at the Annual Meeting (the two advisory proposals related to executive compensation and the auditor ratification proposal) and have no impact on the vote on any proposal for which the vote standard is based on the actual number of votes cast at the meeting (the election of directors). Broker non-votes are not treated as shares entitled to vote and, as a result, have no effect on the outcome of any of the proposals to be voted on by stockholders at the Annual Meeting.

Q:

Can I change my vote or revoke my proxy?

A:

Yes. If you are a stockholder of record, you may change your vote or revoke your proxy at any time before the polls close at the Annual Meeting by:

•

submitting a later-dated proxy relating to the same shares online, by telephone or by mail before the date of the Annual Meeting;

•

delivering a written notice, bearing a date later than your proxy, stating that you revoke the proxy; or

•

participating in the Annual Meeting and voting online at that time at www.virtualshareholdermeeting.com/IACI2017 (although virtual attendance at the Annual Meeting will not, by itself, revoke a proxy).

5

To change your vote or revoke your proxy before the date of the Annual Meeting, follow the instructions provided on your Notice, proxy card or proxy materials to do so online or by telephone, or send a written notice or a new proxy card to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, New York 11717.

If you hold your IAC shares through a broker, bank or other holder of record, follow the instructions that you receive from your broker, bank or other holder of record if you wish to revoke your proxy.

Q:

What if I do not specify a choice for a matter when returning a proxy?

A:

If you do not give specific instructions, proxies that are signed and returned will be voted FOR the election of all director nominees, consistent with the Board's recommendations in the case of the two advisory proposals related to executive compensation and FOR the ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for the 2017 fiscal year.

Q:

How are proxies solicited and who bears the related costs?

A:

IAC bears all expenses incurred in connection with the solicitation of proxies. In addition to solicitations by mail, directors, officers and employees of IAC may solicit proxies from stockholders by telephone, e-mail letter, facsimile or in person.

Following the initial mailing of the Notice and proxy materials, IAC will request brokers, banks and other holders of record to forward copies of these materials to persons for whom they hold shares of IAC common stock and to request authority for the exercise of proxies. In such cases, IAC, upon the request of these holders, will reimburse these parties for their reasonable expenses.

Q:

What should I do if I have questions about the Annual Meeting?

A:

If you have any questions about the Annual Meeting, the various proposals to be voted on at the Annual Meeting and/or how to participate in the Annual Meeting online at www.virtualsharesholdermeeting.com/IACI2017 and vote at that time or would like copies of any of the documents referred to in this proxy statement, contact IAC Investor Relations at 1.212.314.7400 or ir@iac.com.

PROPOSAL 1—ELECTION OF DIRECTORS

Proposal and Required Vote

        At the upcoming Annual Meeting, a board of twelve directors will be elected, each to hold office until the next succeeding annual meeting of stockholders or until such director's successor shall have been duly elected and qualified (or, if earlier, such director's removal or resignation from IAC's Board of Directors). Information concerning director nominees, all of whom are incumbent directors of IAC and have been recommended by the Nominating Committee for re-election, appears below. Although management does not anticipate that any of the persons named below will be unable or unwilling to stand for election, in the event of such an occurrence, proxies may be voted for a substitute designated by the Board.

        The election of each of Edgar Bronfman, Jr., Chelsea Clinton, Barry Diller, Michael D. Eisner, Bonnie S. Hammer, Victor A. Kaufman, Joseph Levin, David Rosenblatt and Alexander von Furstenberg as directors requires the affirmative vote of a plurality of the total number of votes cast by the holders of shares of IAC capital stock voting together as a single class.

        The Board has designated Bryan Lourd, Alan G. Spoon and Richard F. Zannino as nominees for those positions on the Board to be elected by the holders of IAC common stock voting as a separate class. The election of each of them as directors requires the affirmative vote of a plurality of the total number of votes cast by the holders of shares of IAC common stock voting as a separate class.

        Both the Nominating Committee and the full Board recommend that our stockholders vote FOR the election of all director nominees.

Information Concerning Director Nominees

        Background information about each director nominee is set forth below, including information regarding the specific experiences, characteristics, attributes and skills considered in connection with the nomination of each director nominee, all of which the Nominating Committee and the Board believe provide the Company with the perspective and judgment needed to guide, monitor and execute its strategies.

Edgar Bronfman, Jr., age 61, has been a director of IAC (and its predecessors) since February 1998. Mr. Bronfman has served as a Managing Partner of Accretive, LLC, a private equity firm, since 2014.

7

international operations, as well as a high level of financial literacy and insight into the media and entertainment industries. The Board also considered Mr. Bronfman's private equity experience, which the Board believes gives him particular insight into investments in, and the development of, early stage companies.

The Board nominated Mr. Diller because he has been Chairman and Senior Executive since 2010 and prior to that time, served as Chairman and Chief Executive Officer of the Company since 1995, and as a result, possesses a great depth of knowledge and experience regarding the Company and its businesses. In addition, the Board noted Mr. Diller's ability to exercise influence (subject to the Company's organizational documents and Delaware law) over the outcome of matters involving the Company that require stockholder approval given the fact that he and certain members of his family collectively have sole voting and/or investment power over all of shares of IAC Class B common stock outstanding, which shares represent a significant percentage of the voting power of IAC capital stock.

Corporate Governance

        Leadership Structure.    The Company's business and affairs are overseen by its Board of Directors, which currently has twelve members. There are three management representatives on the Board and, of the nine remaining current directors, eight are independent. The Board has standing Audit, Compensation and Human Resources and Nominating Committees, each comprised solely of independent directors, as well as an Executive Committee. For more information regarding director independence and our Board Committees, see the discussion under "Director Independence" beginning on page 13 and Board Committees beginning on page 15. All of our directors play an active role in Board matters, are encouraged to communicate among themselves and directly with the Chairman and Senior Executive and Chief Executive Officer and have full access to Company management at all times.

        Our independent directors meet in scheduled executive sessions without management present at least twice a year and may schedule additional meetings as they deem appropriate. We do not have a lead independent director or any other formally appointed leader for these sessions. The independent membership of our Audit, Compensation and Human Resources and Nominating Committees ensures that directors with no ties to Company management are charged with oversight for all financial reporting and executive compensation related decisions made by Company management, as well as for recommending candidates for Board membership. At each regularly scheduled Board meeting, the Chairperson of each of these committees provides the full Board with an update of all significant matters discussed, reviewed, considered and/or approved by the relevant committee since the last regularly scheduled Board meeting.

        Mr. Diller currently serves as both our Chairman and Senior Executive and has held both positions since December 2010. Effective June 24, 2015, Mr. Levin assumed the role of Chief Executive Officer of IAC. This leadership change provides the Company with the benefit of Mr. Diller's continued oversight of the Company's strategic goals and vision, coupled with the benefit of a full-time Chief Executive Officer dedicated to focusing on the day-to-day management and continued growth of the Company and its operating businesses. At this time, the Company believes that this leadership structure is the most appropriate one for the Company and its stockholders.

        Risk Oversight.    Company management is responsible for assessing and managing the Company's exposure to various risks on a day-to-day basis, which responsibilities include the creation of appropriate risk management programs and policies. Company management has developed and implemented guidelines and policies to identify, assess and manage significant risks facing the Company. In developing this framework, the Company recognized that leadership and success are impossible without taking risks; however, the imprudent acceptance of risks or the failure to appropriately identify and mitigate risks could adversely impact stockholder value. The Board is responsible for overseeing Company management in the execution of its responsibilities and for

12

assessing the Company's approach to risk management. The Board exercises these responsibilities periodically as part of its meetings and through discussions with Company management, as well as through the Board's Audit and Compensation and Human Resources Committees, which examine various components of financial and compensation-related risks, respectively, as part of their responsibilities. In addition, an overall review of risks is inherent in the Board's consideration of the Company's long-term strategies and in the transactions and other matters presented to the Board, including significant capital expenditures, acquisitions and divestitures and financial matters. The Board's role in risk oversight of the Company is consistent with the Company's leadership structure, with the Chairman and Senior Executive, Chief Executive Officer and other members of senior management having responsibility for assessing and managing the Company's risk exposure, and the Board and its committees providing oversight in connection with those efforts.

        Compensation Risk Assessment.    We periodically conduct risk assessments of our compensation policies and practices for our employees, including those related to our executive compensation programs. The goal of these assessments is to determine whether the general structure of the Company's compensation policies and programs and the administration of these programs pose any material risks to the Company. The findings of any risk assessment are discussed with the Compensation and Human Resources Committee. Based upon our assessments, we believe that our compensation policies and programs do not encourage excessive or unnecessary risk-taking and are not reasonably likely to have a material adverse effect on the Company.

        Director Independence.    Under the Marketplace Rules of The Nasdaq Stock Market, LLC (the "Marketplace Rules"), the Board has a responsibility to make an affirmative determination that those members of the Board who serve as independent directors do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In connection with the independence determinations described below, the Board reviewed information regarding transactions, relationships and arrangements relevant to independence, including those required by the Marketplace Rules. This information is obtained from director responses to questionnaires circulated by Company management, as well as from Company records and publicly available information. Following these determinations, Company management monitors those transactions, relationships and arrangements that were relevant to such determinations, as well as periodically solicits updated information potentially relevant to independence from internal personnel and directors, to determine whether there have been any developments that could potentially have an adverse impact on the Board's prior independence determinations.

        In February 2017, the Board determined that each of Messrs. Bronfman, Eisner, Lourd, Rosenblatt, Spoon and Zannino and Mses. Clinton and Hammer is independent. In connection with these determinations, the Board considered that in some cases in the ordinary course of business, IAC and its businesses sell products and services to, purchase products and services from, co-invest with, develop and produce projects with and/or make donations to entities at which certain directors are employed or serve as directors, or over which certain directors otherwise exert control. Furthermore, the Board considered whether there were any payments made to (or received from) such entities by IAC and its businesses. No relationships or payments considered were determined to be of the type that would: (i) preclude a finding of director independence under the Marketplace Rules or (ii) otherwise interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

        Of the remaining incumbent directors, Messrs. Diller, Kaufman and Levin are executive officers of the Company and Mr. von Furstenberg is Mr. Diller's stepson. Given these relationships, none of these directors is independent.

        In addition to the satisfaction of the director independence requirements set forth in the Marketplace Rules, members of the Audit and Compensation and Human Resources Committees have

13

also satisfied separate independence requirements under the current standards imposed by the SEC and the Marketplace Rules for audit committee members and by the SEC, the Marketplace Rules and the Internal Revenue Service for compensation committee members.

        Director Nominations.    The Nominating Committee identifies, reviews and evaluates individuals qualified to become Board members and recommends candidates to the Board. While there are no specific requirements for eligibility to serve as a director of IAC, in evaluating candidates, the Nominating Committee will consider (regardless of how the candidate was identified or recommended) whether the professional and personal ethics and values of the candidate are consistent with those of IAC, whether the candidate's experience and expertise would be beneficial to the Board, whether the candidate is willing and able to devote the necessary time and energy to the work of the Board and whether the candidate is prepared and qualified to represent the best interests of IAC's stockholders. While the Board does not have a formal diversity policy, the Nominating Committee also considers the overall diversity of the experiences, characteristics, attributes, skills and backgrounds of candidates relative to those of other Board members and those represented by the Board as a whole to ensure that the Board has the right mix of skills, expertise and background.

        The Board does not have a formal policy regarding the consideration of director nominees recommended by stockholders, as to date IAC has not received any such recommendations. However, the Board would consider such recommendations if made in the future. Stockholders who wish to make such a recommendation should send the recommendation to IAC, 555 West 18^th Street, New York, New York 10011, Attention: Corporate Secretary. The envelope must contain a clear notation that the enclosed letter is a "Director Nominee Recommendation." The letter must identify the author as a stockholder, provide a brief summary of the candidate's qualifications and history, together with an indication that the recommended individual would be willing to serve (if elected), and must be accompanied by evidence of the sender's stock ownership. Any director recommendations will be reviewed by the Corporate Secretary and the Chairman, and if deemed appropriate, forwarded to the Nominating Committee for further review. If the Nominating Committee believes that the candidate fits the profile of a director described above, the recommendation will be shared with the entire Board.

        Communications with the IAC Board.    Stockholders who wish to communicate with IAC's Board of Directors or a particular director may send any such communication to IAC, 555 West 18^th Street, New York, New York 10011, Attention: Corporate Secretary. The mailing envelope must contain a clear notation indicating that the enclosed letter is a "Stockholder—Board Communication" or "Stockholder—Director Communication." All such letters must identify the author as a stockholder, provide evidence of the sender's stock ownership and clearly state whether the intended recipients are all members of the Board or a particular director or directors. The Corporate Secretary will then review such correspondence and forward it to the Board, or to the specified director(s), if appropriate.

The Board and Board Committees

        The Board.    The Board met five times and acted by written consent three times during 2016. During 2016, all then incumbent directors attended at least 75% of the meetings of the Board and the Board committees on which they served. Directors are not required to attend annual meetings of IAC stockholders. One member of the Board of Directors attended IAC's 2016 Annual Meeting of Stockholders.

        The Board currently has four standing committees: the Audit Committee, the Compensation and Human Resources Committee, the Nominating Committee and the Executive Committee.

The Audit Committee is appointed by the Board to assist the Board with a variety of matters described in the charter, which include monitoring: (i) the integrity of IAC's financial statements, (ii) the effectiveness of IAC's internal control over financial reporting, (iii) the qualifications and independence of IAC's independent registered public accounting firm, (iv) the performance of IAC's internal audit function and independent registered public accounting firm, (v) IAC's risk assessment and risk management policies as they relate to financial and other risk exposures and (vi) the compliance by IAC with legal and regulatory requirements. In fulfilling its purpose, the Audit Committee maintains free and open communication among its members, the Company's independent registered public accounting firm, the Company's internal audit function and Company management. The formal report of the Audit Committee is set forth on page 18.

The Compensation and Human Resources Committee may form and delegate authority to subcommittees and may delegate authority to one or more of its members. The

15

Compensation and Human Resources Committee may also delegate to one or more of the Company's executive officers the authority to make grants of equity-based compensation to eligible individuals (other than directors or executive officers) to the extent allowed under applicable law. For additional information on IAC's processes and procedures for the consideration and determination of executive compensation and the related roles of the Compensation and Human Resources Committee, Company management and consultants, see the discussion under "Compensation Discussion and Analysis" generally beginning on page 21.

        Executive Committee.    The Executive Committee has all the power and authority of the Board of Directors of IAC, except those powers specifically reserved to the Board by Delaware law or IAC's organizational documents.

PROPOSAL 2—ADVISORY VOTE ON EXECUTIVE COMPENSATION (THE SAY ON PAY VOTE)

        As required pursuant to Section 14 of the Exchange Act of 1934, as amended (the "Exchange Act"), we are seeking a non-binding advisory vote from our stockholders to approve the compensation of our named executives for 2016. This proposal, which we refer to as the "say on pay vote," is not intended to address any specific item of compensation, but rather our overall compensation program and policies relating to our named executives.

        As described in detail under the caption Compensation Discussion and Analysis, beginning on page 21, our executive officer compensation program is designed to provide the level of compensation necessary to attract, retain, motivate and reward talented and experienced executives and to motivate them to achieve short-term and long-term goals, thereby enhancing stockholder value and creating a successful company.

        We believe that our executive officer compensation program, with its balance of short-term and long-term incentives, rewards sustained performance that is aligned with long-term stockholder interests. Accordingly, we believe that the compensation paid to our named executives in 2016 pursuant to our executive officer compensation program was fair and appropriate and are asking our stockholders to vote FOR the adoption of the following resolution:

"RESOLVED, that the Company's stockholders approve, on an advisory basis, the compensation of the Company's named executives for 2016, as disclosed in this proxy statement, pursuant to the U.S. Securities and Exchange Commission's compensation disclosure rules, including the Compensation Discussion and Analysis, the Executive Compensation tables and the related narrative discussion."

        The approval, on an advisory basis, of the say on pay vote proposal requires the affirmative vote of the holders of a majority of the voting power of shares of IAC capital stock present at the Annual Meeting in person or represented by proxy and voting together. The vote is advisory in nature and therefore not binding on us or our Board. However, our Board and Compensation and Human Resources Committee value the opinions of all of our stockholders and will consider the outcome of this vote when making future compensation decisions for our named executives. Following its 2011 Annual Meeting of Stockholders, the Company decided to seek a say on pay vote every three years. Accordingly, the Company last sought a say on pay vote at its 2014 Annual Meeting of Stockholders.

16

        The Board recommends that our stockholders vote FOR the advisory vote on executive compensation.

PROPOSAL 3—ADVISORY VOTE ON THE FREQUENCY OF HOLDING THE SAY ON PAY VOTE

        Section 14 of the Exchange Act also requires us to seek a non-binding advisory vote from our stockholders regarding the frequency of holding the advisory vote on executive compensation in the future. In casting your advisory vote, you may indicate whether you prefer that we seek an advisory vote every one, two or three years. You may also abstain from voting on this matter.

        After thoughtful consideration, our Compensation and Human Resources Committee and the Board believe that holding an advisory vote on executive compensation every three years is the most appropriate policy for the Company and its stockholders at this time. Our Board and the Compensation and Human Resources Committee believe that a triennial vote more closely mirrors the long-term nature of a significant portion of our executive officer compensation program and will discourage short-term thinking and, as a result, stockholder analysis of our performance and compensation practices would be more fully informed when viewed over a three-year period. Moreover, allowing more time in between the advisory votes on executive compensation would provide a greater opportunity for our Board and Compensation and Human Resources Committee to engage in meaningful analysis of any compensation issues and consideration of any stockholder concerns.

        The approval, on an advisory basis, of the frequency of holding the say on pay vote proposal requires the affirmative vote of the holders of a majority of the voting power of shares of IAC capital stock present at the Annual Meeting in person or represented by proxy and voting together. However, if no choice receives a majority of votes, then the option on the frequency of the advisory vote that receives the highest number of votes cast by stockholders will be considered by the Board as the recommendation of our stockholders as to the frequency of holding future say on pay votes. The vote is advisory in nature and therefore not binding on us or our Board. However, our Board values the opinions of all of our stockholders and will consider the outcome of this vote when making future decisions on the frequency with which we will hold an advisory vote on executive compensation.

        The Board recommends that our stockholders vote for holding the say on pay vote once EVERY THREE YEARS.

        Section 14 of the Exchange Act requires us to seek a non-binding advisory vote from our stockholders on the frequency of seeking the say on pay vote every six years. Accordingly, we last sought this non-binding advisory vote at our 2011 Annual Meeting of Stockholders and the next such vote is scheduled to be held at the Company's 2023 Annual Meeting of Stockholders.

PROPOSAL 4—RATIFICATION OF APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        Subject to stockholder ratification, the Audit Committee of the Board of Directors has appointed Ernst & Young LLP as IAC's independent registered public accounting firm for the fiscal year ending December 31, 2017. Ernst & Young LLP has served as IAC's independent registered public accounting firm for many years and is considered by Company management to be well qualified.

        A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will be given an opportunity to make a statement if he or she so chooses and will be available to respond to appropriate questions.

        Ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm requires the affirmative vote of the holders of a majority of the voting power of the shares of IAC capital stock present at the Annual Meeting in person or represented by proxy and voting together.

        The Board recommends that our stockholders vote FOR the ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for the fiscal year ending December 31, 2017.

AUDIT COMMITTEE MATTERS

Audit Committee Report

        The Audit Committee functions pursuant to a written charter adopted by the Board of Directors, the most recent version of which is attached as Appendix A to this proxy statement. The Audit Committee charter governs the operations of the Audit Committee and sets forth its responsibilities, which include providing assistance to the Board of Directors with the monitoring of: (i) the integrity of IAC's financial statements, (ii) the effectiveness of IAC's internal control over financial reporting, (iii) the qualifications and independence of IAC's independent registered public accounting firm, (iv) the performance of IAC's internal audit function and independent registered public accounting firm, (v) IAC's risk assessment and risk management policies as they relate to financial and other risk exposures and (vi) the compliance by IAC with legal and regulatory requirements. It is not the duty of the Audit Committee to plan or conduct audits or to determine that IAC's financial statements and disclosures are complete, accurate and have been prepared in accordance with generally accepted accounting principles and applicable rules and regulations. These are the responsibilities of Company management and IAC's independent registered public accounting firm.

        In fulfilling its responsibilities, the Audit Committee has reviewed and discussed the audited consolidated financial statements of IAC for the fiscal year ended December 31, 2016 with IAC's management and Ernst & Young LLP.

        The Audit Committee has discussed with Ernst & Young the matters required to be discussed by PCAOB Auditing Standard 1301, "Communications with Audit Committees." In addition, the Audit Committee has received the written disclosures and letter from Ernst & Young required by applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young's communications with the Audit Committee concerning independence and has discussed with Ernst & Young its independence from IAC and its management.

        In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements of IAC for the fiscal year ended December 31, 2016 be included in IAC's Annual Report on Form 10-K for the year ended December 31, 2016 for filing with the SEC.

Audit and Non-Audit Services Pre-Approval Policy

        The Audit Committee has a policy governing the pre-approval of all audit and permitted non-audit services performed by IAC's independent registered public accounting firm in order to ensure that the provision of these services does not impair such firm's independence from IAC and its management. Unless a type of service to be provided by IAC's independent registered public accounting firm has received general pre-approval, it requires specific pre-approval by the Audit Committee. Any proposed services in excess of pre-approved cost levels also require specific pre-approval by the Audit Committee. In all pre-approval instances, the Audit Committee considers whether such services are consistent with SEC rules regarding auditor independence.

19

        All Tax services require specific pre-approval by the Audit Committee. In addition, the Audit Committee has designated specific services that have the pre-approval of the Audit Committee (each of which is subject to pre-approved cost levels) and has classified these pre-approved services into one of three categories: Audit, Audit-Related and All Other (excluding Tax). The term of any pre-approval is 12 months from the date of the pre-approval, unless the Audit Committee specifically provides for a different period. The Audit Committee revises the list of pre-approved services from time to time. Pre-approved fee levels for all services to be provided by IAC's independent registered public accounting firm are established periodically from time to time by the Audit Committee.

        Pursuant to the pre-approval policy, the Audit Committee may delegate its authority to grant pre-approvals to one or more of its members, and has currently delegated this authority to its Chairperson. The decisions of the Chairperson (or any other member(s) to whom such authority may be delegated) to grant pre-approvals must be presented to the full Audit Committee at its next scheduled meeting. The Audit Committee may not delegate its responsibilities to pre-approve services to Company management.

COMPENSATION DISCUSSION AND ANALYSIS

Philosophy and Objectives

        Our executive officers whose compensation is discussed in this compensation discussion and analysis (the "CD&A"), and to whom we refer to as our named executive officers in this CD&A (the "NEOs") are:

•

Barry Diller, Chairman and Senior Executive;

•

Joseph Levin, Chief Executive Officer;

•

Victor Kaufman, Vice Chairman;

•

Glenn Schiffman, Executive Vice President and Chief Financial Officer (since April 2016);

•

Mark Stein, Executive Vice President and Chief Strategy Officer (since January 2016); and

•

Gregg Winiarski, Executive Vice President and General Counsel.

        Our executive officer compensation program is designed to increase long-term stockholder value by attracting, retaining, motivating and rewarding leaders with the competence, character, experience and ambition necessary to enable the Company to meet its growth objectives.

        Although IAC is a publicly traded company, we attempt to foster an entrepreneurial culture, and attract and retain senior executives with entrepreneurial backgrounds, attitudes and aspirations. Accordingly, when attempting to recruit and retain our executive officers, as well as other executives who may become executive officers at a later time, we compete not only with other public companies, but also with earlier stage companies, companies funded by private equity and venture capital firms and professional firms. We structure our compensation program so that we can compete in this varied marketplace for talent, with an emphasis on variable, contingent compensation and long-term equity ownership.

        While we consider market data in establishing broad compensation programs and practices and may periodically benchmark the compensation associated with particular executive positions, we do not definitively rely on competitive survey data or any benchmarking information in establishing executive compensation. The Company makes decisions based on a host of factors particular to a given executive's situation, including its firsthand experience with the competition for recruiting executives and its understanding of the current environment, and believes that over-reliance on survey data, or a benchmarking approach, is too rigid and stale for the dynamic and fast changing marketplace for talent in which we compete.

        Similarly, we believe that arithmetic approaches to measuring and rewarding short-term performance often fail to adequately take into account the multiple factors that contribute to success at the individual executive and business level. In any given period, the Company may have multiple objectives, and these objectives, and their relative importance, often change as competitive and strategic landscapes shift. Accordingly, we have historically avoided the use of strict formulas in our annual bonus program, believing that they often over-compensate or under-compensate a given performance level. We instead rely primarily on an approach that, while based on clear objectives, is not formulaic and allows for the exercise of discretion in setting final bonus amounts.

        In addition, we are of the view that long-term incentive compensation in the form of equity awards aligns the interests of executives with the interests of our long-term shareholders, and to further this important goal, equity awards play a prominent role in our overall compensation program. We have used non-qualified stock options as the predominant equity incentive vehicle for our executives for many years. We use this equity incentive instrument primarily for the sake of simplicity given that the value from stock option awards is directly dependent on appreciation in the Company's stock price and

21

therefore provides an objectively measurable goal, and a belief that it would, in general, make the Company more competitive in recruiting talented executives and employees. From time to time, however, executives have been awarded restricted stock units in addition to, or in lieu of, stock option awards, depending on individual circumstances, and in 2016 two of our executives was awarded restricted stock units (as described below).

        We believe that the Company's executive officer compensation program puts the substantial majority of compensation at risk, rewards both individual executive and corporate performance in a targeted fashion, pays amounts appropriate to attract and retain those key individuals necessary to grow the Company and aligns the interests of our key executives with the interests of our stockholders. We continuously evaluate our program and make changes as we deem appropriate.

Roles and Responsibilities

        The Compensation and Human Resources Committee of the Company's Board of Directors (for purposes of this CD&A, the "Committee") has primary responsibility for establishing the compensation of the Company's executive officers. All compensation decisions referred to throughout this CD&A have been made by the Committee, based (in part) on recommendations from Mr. Diller and Mr. Levin (as described below). The Committee currently consists of Ms. Hammer (Chairperson) and Mr. Rosenblatt.

        The executive officers participate in structuring Company-wide compensation programs and in establishing appropriate bonus and equity pools. In early 2017, Messrs. Diller and Levin met with the Committee and discussed their views of corporate and individual executive officer performance for 2016 for Messrs. Kaufman, Schiffman, Stein and Winiarski, and their recommendations for annual bonuses for those executive officers. Mr. Diller also discussed Mr. Levin's performance, and his views on his own performance, with the Committee. Following these discussions, the Committee met in executive sessions to discuss these recommendations. After consideration of these recommendations, the Committee ultimately determined the annual bonus amount for each executive officer.

        In establishing a given executive officer's compensation package, each individual component is evaluated independently and in relation to the package as a whole. Prior earning histories and outstanding long-term compensation arrangements are also reviewed and taken into account. However, we do not believe in any formulaic relationship or targeted allocation between these elements. Instead, each individual executive's situation is evaluated on a case-by-case basis each year, considering the variety of relevant factors at that time.

        From time to time, the Committee has solicited the advice of consulting firms and engaged legal counsel. No such consulting firms or legal counsel were engaged during 2016.

        In addition, from time to time, the Company may solicit survey or peer compensation data from various consulting firms. In 2016, the Company engaged Mercer (US) Inc. to provide comparative market data in connection with the Company's own analysis of its equity compensation practices, but neither Mercer nor any other compensation consultant engaged by the Company had any role in determining or recommending the amount or form of executive compensation for 2016.

Compensation Elements

        Our compensation packages for executive officers primarily consist of salary, annual bonuses, IAC equity awards and, in certain instances, perquisites and other benefits.

22

Salary

        We typically negotiate a new executive officer's starting salary upon arrival, based on the executive's prior compensation history, prior compensation levels for the particular position within the Company, the Company's New York City location, salary levels of other executive officers within the Company and salary levels available to the individual in alternative opportunities. Salaries can increase based on a number of factors, including the assumption of additional responsibilities and other factors which demonstrate an executive officer's increased value to the Company. No executive officer's salary was adjusted during 2016.

Annual Bonuses

General. We establish bonus levels through a two-pronged process. First, at the beginning of each year, the Committee sets performance objectives, which historically have been tied to the achievement of EBITDA (as defined below), revenue or share price performance targets during the forthcoming year, and maximum bonus amounts. In general, these performance targets are minimum acceptable performance conditions, but with respect to which there is substantial uncertainty when we establish them. The establishment of performance targets and maximum bonus amounts is undertaken primarily to satisfy the requirements of Section 162(m) of the Internal Revenue Code, as amended. Satisfaction of one or more of the performance targets established by the Committee allows for the payment of bonuses that will be deductible by the Company for federal income tax purposes, should any bonuses be awarded to the Company's named executive officers. However, satisfaction of the applicable performance targets does not obligate the Committee to approve any specific bonus amount for any executive officer, and the Committee has historically reduced the maximum bonus amount based on a discretionary assessment of Company and, to a lesser extent, individual performance. In making its determinations regarding individual annual bonus amounts, the Committee considers a variety of factors, such as growth in profitability or achievement of strategic objectives by the Company, and an individual's performance and contribution to the Company. The Committee does not quantify the weight given to any specific element or otherwise follow a formulaic calculation. Rather, the Committee engages in an overall assessment of appropriate bonus levels based on a subjective interpretation of all relevant criteria. This process is designed to permit the Company to deduct the bonus compensation paid to executives for income tax purposes.

        The definition of EBITDA used for establishing Section 162(m) performance objectives comes from IAC's 2013 Stock and Annual Incentive Plan, and is as follows: "EBITDA" means for any period, operating profit (loss) plus, if applicable: (i) depreciation, (ii) amortization and impairment of intangibles, (iii) goodwill impairment, (iv) non-cash compensation expense, (v) restructuring charges, (vi) non cash write-downs of assets, (vii) charges relating to disposal of lines of business, (viii) litigation settlement amounts and (ix) costs incurred for proposed and completed acquisitions.

2016 Bonuses. For 2016, the Committee predicated the payment of bonuses to executive officers on attaining: (i) EBITDA in any of the four consecutive calendar quarters beginning with the second quarter of 2016 at least equal to EBITDA in the corresponding calendar quarter twelve months before, (ii) revenue in any of the four consecutive calendar quarters beginning with the second quarter of 2016 at least equal to revenue in the corresponding calendar quarter twelve months before or (iii) share price growth of at least 5% over $42.39 (the closing price of the Company's common stock on February 10, 2016) on any 20 trading days during the period beginning on February 11, 2016 through December 31, 2016. Two of the targets were met. After concluding that the threshold performance targets for the payment of bonuses had been achieved, the Committee then exercised its right to reduce bonus amounts for each individual executive officer from the maximum level established. In setting actual bonus levels, the Committee considered a variety of factors, including:

23

•

Revenue and Adjusted EBITDA results.  Revenue decreased modestly over the prior year, reflecting challenges in our Publishing and Applications segments, offset by strong growth at Match Group and HomeAdvisor. Adjusted EBITDA increased modestly in 2016, reflecting strong growth at Match Group and HomeAdvisor and reduced losses at Vimeo;

•

Capitalization and cash position.  The Company repatriated over $315 million to stockholders during 2016 by way of share repurchases. In addition, during 2016: (i) the Company repurchased $126 million of its outstanding senior notes, and (ii) Match Group issued $400 million of 6.375% senior notes, repaid $450 million of its term loan and amended its term loan to reduce the interest rate payable on the outstanding balance, positioning each of us and Match Group for long term growth as we each continue to invest in our respective businesses and identify new opportunities for expansion; and

•

Strategic initiatives.  The Company took steps to positively advance the strategic position of several of its businesses. As part of its continuing review of its collection of assets, the Company: (i) provided for additional investment in those of its businesses where the Company believes there is upside opportunity, for example HomeAdvisor and Vimeo, (ii) restructured certain of its businesses, positioning them for future growth, including the businesses within our Publishing and Applications segments, and (iii) divested itself of several non-core assets, including Shoebuy, PriceRunner and Ask.fm. In addition, the Company focused on cost-cutting efforts throughout the organization during the year.

        While the factors noted above were the primary ones considered in setting bonus award amounts, the Committee also considered each executive officer's role and responsibilities, the relative contributions made by each executive officer during the year and the relative size of the bonuses paid to the other executive officers. With respect to 2016 bonuses for our NEOs, the Committee considered the following: (i) with respect to Mr. Diller, his role in providing strategic direction for the Company overall, (ii) with respect to Mr. Levin, his continuing focus on managing the day-to-day business operations of the Company, including stepping in as acting Chief Executive Officer of Vimeo and participating in the development of strategic initiatives for the Company, (iii) with respect to Mr. Kaufman, his participation in strategic oversight of the Company, (iv) with respect to Mr. Schiffman, his new role as Executive Vice President and Chief Financial Officer and his oversight of cost-cutting initiatives, (v) with respect to Mr. Stein, participating in the development of strategy for several of the Company's businesses and (vi) with respect to Mr. Winiarski, his role in managing the successful completion of a number of acquisitions and dispositions of businesses and investments.

        As noted above, in setting individual bonus amounts, the Committee did not quantify the weight assigned to any specific factor, nor did it apply a formulaic calculation. In setting bonus amounts, the Committee generally considered the Company's overall performance, the amount of bonus for each NEO relative to other Company executives and the recommendations of the Chairman and Senior Executive and the Chief Executive Officer. In addition, the Committee considered achievements in 2016 as compared to achievements and bonus levels in prior years.

        Executive officer bonuses tend to be highly variable from year-to-year depending on the performance of the Company and, in certain circumstances, individual executive officer performance. Accordingly, we believe our executive officer bonus program provides strong incentives to reach the Company's annual goals.

Long-Term Incentives

General. Due to our entrepreneurial philosophy, we believe that providing a meaningful equity stake in our business is essential to create compensation opportunities that can compete, on a risk-adjusted basis, with entrepreneurial employment alternatives. In addition, we believe that ownership shapes behavior, and that by providing compensation in the form of equity awards, we align

24

executive officer incentives with stockholder interests in a manner that we believe drives superior performance over time.

        While there is currently no formal stock ownership or holding requirement for executive officers, our executive officers generally have historically held a significant portion of their stock awards (net of tax withholdings) well beyond the relevant vesting dates.

        In establishing equity awards for an executive officer for any given period, the amount of outstanding unvested and/or unexercised equity awards, as well as previously earned or exercised awards, is reviewed and evaluated on an individual-by-individual basis. In setting award levels, the predominant considerations are providing the executive officer with effective retention incentives, appropriate reward for past performance, incentives for strong future performance and competitive conditions. The annual corporate performance factors relevant to setting bonus amounts, while considered, are generally less relevant in determining the type and level of equity awards, as the awards tend to be more forward looking, and are a longer-term retention and reward instrument relative to our annual bonuses.

        The Company's usual practice is to schedule the Committee meetings at which awards are to be made in advance, without regard to the timing of the release of earnings or other material information.

2016 Equity Awards. In February 2016, the Committee granted 200,000 stock options to Mr. Levin, 150,000 stock options to Mr. Stein and 100,000 stock options to Mr. Winiarski. The options vest 25% a year, on the first four anniversaries of the grant date, and have an exercise price equal to the closing price of the Company's common stock on the grant date. Also in February 2016, Mr. Levin received 100,000 restricted stock units, vesting in one lump sum installment on the third anniversary of the grant date, and Mr. Kaufman received a restricted stock unit award with a dollar value of $350,000 in accordance with the terms of his employment agreement, vesting in thirds on the first three anniversaries of the grant date. In April 2016, upon joining the Company, Mr. Schiffman received 200,000 stock options that vest 25% a year, on the first four anniversaries of the grant date, and have an exercise price equal to the closing price of the Company's common stock on the grant date. Mr. Diller did not receive an equity award in 2016, as the Committee granted him one million stock options in 2015, with the Committee noting at that time the Company's history of granting Mr. Diller equity awards once every few years (and the Committee's intention to remain consistent with that approach).

        We believe these awards provide meaningful retention and performance incentives for our executive officers.

2017 Equity Awards. In February 2017, the Committee granted 300,000 stock options to Mr. Levin, 150,000 stock options to each of Messrs. Schiffman and Stein, and 100,000 stock options to Mr. Winiarski. The options vest 25% a year, on the first four anniversaries of the grant date, and have an exercise price equal to the closing price of the Company's common stock on the grant date. Also in February 2017, Mr. Kaufman received a restricted stock unit award with a dollar value of $350,000 in accordance with the terms of his employment agreement, vesting in thirds on the first three anniversaries of the grant date.

2016 Employment Agreement

New Employment Agreement for Mr. Schiffman. Effective April 7, 2016 (the "Effective Date"), IAC and Mr. Schiffman entered into an employment agreement (the "Employment Agreement"), pursuant to which Mr. Schiffman became the Company's Executive Vice President and Chief Financial Officer. The Employment Agreement has a scheduled term of one (1) year from the Effective Date and provides for automatic renewals for successive one (1) year terms absent written notice from IAC or Mr. Schiffman ninety (90) days prior to the expiration of the then current term.

25

        The Employment Agreement provides that Mr. Schiffman will be eligible to receive an annual base salary (currently $600,000), discretionary annual cash bonuses, equity awards and such other employee benefits as may be reasonably determined by the Committee. Upon joining IAC, Mr. Schiffman was granted 200,000 IAC stock options that vest 25% a year, on the first four anniversaries of the grant date, subject to Mr. Schiffman's continued employment with IAC, and have an exercise price equal to the closing price of the Company's common stock on the Effective Date (the "2016 Options").

        Upon certain involuntary terminations of Mr. Schiffman's employment and subject to the execution and non-revocation of a release and compliance with the restrictive covenants set forth below: (i) IAC will continue to pay Mr. Schiffman his annual base salary for one (1) year following such termination, (ii) the 2016 Options shall vest as of such date of termination, (iii) all other IAC equity awards (including any cliff vesting awards, which shall be pro-rated as though such awards had an annual vesting schedule) held by Mr. Schiffman that would have otherwise vested during the one (1) year period following such termination shall vest as of the date of such termination and (iv) all vested and outstanding IAC stock options held by Mr. Schiffman as of the date of such termination (including any stock options that vested pursuant to the acceleration rights described above), shall remain outstanding and exercisable for eighteen (18) months from the date of such termination.

        Pursuant to his agreement, Mr. Schiffman is bound by a covenant not to compete with IAC's businesses during the term of his employment and for twelve (12) months after certain involuntary terminations and covenants not to solicit IAC's employees or business partners during the term of his employment and for eighteen (18) months after such a termination. In addition, Mr. Schiffman agreed not to use or disclose any confidential information of IAC or its affiliates.

Change of Control

        The Company's equity awards for senior executive officers generally include a so-called "double-trigger" change of control provision, which provides for the acceleration of the vesting of outstanding equity awards in connection with a change of control only when an award holder suffers an involuntary termination of employment during the two (2) year period following such change of control. The Committee believes that providing for the acceleration of the vesting of equity awards after an involuntary termination will assist in the retention of our executive officers through a change of control transaction. For purposes of this discussion and the discussion below under the heading "Severance," we use the term "involuntary termination" to mean both a termination by the Company without "cause" and a resignation by the executive for "good reason" or similar construct.

Severance

        We generally provide executive officers with some amount of salary continuation and the acceleration of the vesting of some equity awards in the event of an involuntary termination of employment. Because we tend to promote our executive officers from within, after competence and commitment have generally been established, we believe that the likelihood of the vesting of equity awards being accelerated is typically low, and yet we believe that through providing this benefit we increase the retentive effect of our equity program, which serves as our most important retention incentive. The Company generally does not provide for the acceleration of the vesting of equity awards in the event an executive voluntarily resigns from the Company.

Other Compensation

        General.    We provide Mr. Diller with various non-cash benefits as part of his overall compensation program. Under certain limited circumstances, other executive officers have also received non-cash benefits. The value of these benefits is calculated under appropriate rules and is taken into account as a component of compensation when establishing overall compensation levels. The value of all non-cash

26

benefits is reported under the "All Other Compensation" column in the Summary Compensation Table on page 29 pursuant to applicable SEC rules. Our executive officers do not participate in any deferred compensation or retirement programs other than the Company's 401(k) plan. Other than a tax gross-up on certain relocation benefits provided to Mr. Schiffman in connection with his moving to the New York City metropolitan area to assume the role of Executive Vice President and Chief Financial Officer, we did not gross-up any benefits provided to any executive officer in 2016. Other than those described specifically below, our executive officers do not partake in any benefit programs, or receive any significant perquisites, distinct from the Company's other employees.

        Mr. Diller.    Pursuant to Company policy, Mr. Diller is required to travel, both for business and personal purposes, on corporate aircraft. In addition to serving general security interests, this means of travel permits him to travel non-stop and without delay, to remain in contact with the Company while he is traveling, to change his plans quickly in the event Company business requires and to conduct confidential Company business while flying, be it telephonically, by e-mail or in person. These interests are similarly furthered on both business and personal flights, as Mr. Diller typically provides his services to the Company while traveling in either case. Nonetheless, the incremental cost to the Company of his travel for personal purposes is reflected as compensation to Mr. Diller from the Company, and is taken into account in establishing his overall compensation package. For certain personal use of Company-owned aircraft, Mr. Diller reimburses the Company at the maximum rate allowable under applicable rules of the Federal Aviation Administration. See the disclosure under the caption "Relationships Involving Significant Stockholders, Named Executives and Directors—Relationships Involving Mr. Diller" on page 45.

        Additionally, the Company provides Mr. Diller with access to certain automobiles for business and personal use. We also provide certain Company-owned office space and IT equipment for use by certain individuals who work for Mr. Diller personally. These uses are valued by the Company at their incremental cost to the Company or, in the case of the use of office space (where there is no discernible incremental cost), at the cost used for internal allocations of office space for corporate purposes.

        Mr. Levin.    Pursuant to Company policy, Mr. Levin is encouraged to travel, both for business and personal purposes, on corporate aircraft for the same reasons as set forth above for Mr. Diller. The incremental cost to the Company of his travel for personal purposes is reflected as compensation to Mr. Levin from the Company, and is taken into account in establishing his overall compensation package.

        Mr. Kaufman.    Mr. Kaufman is entitled to use corporate aircraft chartered by the Company for a certain amount of personal travel annually. However, Mr. Kaufman reimburses the Company for the Company's incremental cost of such travel and/or pays the relevant third parties directly, and therefore the value of such travel is not treated as compensation to Mr. Kaufman. Typically, Mr. Kaufman's spouse accompanies him on personal and business flights at no incremental cost to the Company.

        Mr. Schiffman.    As part of the agreement for Mr. Schiffman to move to the New York City metropolitan area to accept the position of Executive Vice President and Chief Financial Officer, the Company agreed to compensate Mr. Schiffman for various costs of relocating from Austin, Texas, including airfare for certain trips between the New York City metropolitan area and Austin, Texas until his family joined him in the New York City metropolitan area during the third quarter of 2016, the payment of certain brokerage fees in connection with the disposition of his home, costs of temporary housing, moving expenses and associated tax gross-ups. We do not expect these amounts to be recurring, and though the applicable compensation disclosure rules require us to disclose the value of these items as compensation, we did not take them into account in determining the other components of Mr. Schiffman's compensation, as we view them as a cost to the Company in facilitating Mr. Schiffman's move to the New York City metropolitan area.

27

Tax Deductibility

        Whenever possible, we endeavor to structure our compensation program so that the compensation we pay is deductible by the Company for federal income tax purposes. Because of the use of performance conditions in connection with our equity awards and annual bonuses, and the fact that no salaries are in excess of one million dollars, these three components are generally deductible by the Company. However, under applicable rules of the Internal Revenue Service, the personal use of corporate aircraft leads to a disallowance of the deduction of certain airplane and related costs.

COMPENSATION AND HUMAN RESPOURCES COMMITTEE REPORT

        The Compensation and Human Resources Committee has reviewed the Compensation Discussion and Analysis and discussed it with Company management. In reliance on its review and the discussions referred to above, the Compensation and Human Resources Committee recommended to the Board that the Compensation Discussion and Analysis be included in IAC's 2016 Annual Report on Form 10-K and this proxy statement.

Counsel and Secretary

(1)

Reflects the dollar value of RSU awards, calculated by multiplying the closing price of IAC common stock on the grant date by the number of RSUs awarded.

(2)

Unless otherwise indicated, these amounts represent the grant date fair value of stock option awards using the Black-Scholes option pricing model. For details regarding the assumptions used to calculate these amounts in 2016, see footnote 3 to the "Grants of Plan-Based Awards in 2016" table on page 31. In 2015, Mr. Levin was granted a stock option award with vesting tied to continued employment and a performance stock option award with vesting tied to continued employment and exercisability tied to the satisfaction of certain performance-based conditions related to the Company's stock price. Accordingly, in the case of the related amount in the table above, $3,980,000 of this amount represents the grant date fair value of the stock option award with vesting tied to continued employment using the Black-Scholes option pricing model and $4,086,000 of this amount represents the grant date fair value of the performance stock option award using a lattice model that incorporates a Monte Carlo simulation of the Company's stock price.

Additional information regarding all other compensation amounts for each named executive in 2016 is as follows:

	Barry Diller		Joseph Levin		Victor A. Kaufman		Glenn H. Schiffman		Mark Stein		Gregg Winiarski

(a)

Pursuant to the Company's Airplane Travel Policy, Mr. Diller is required to travel by Company-owned or chartered aircraft for both business and personal purposes and Mr. Levin is encouraged to use Company aircraft for business and personal travel when doing so would serve the interests of the Company. See the discussion regarding airplane travel under "Compensation Discussion and Analysis" on page 27. We calculate the incremental cost to the Company for personal use of Company aircraft based on the average variable operating costs to the Company. Variable operating costs include fuel, certain maintenance costs, navigation fees, on-board catering, landing fees, crew travel expenses and other miscellaneous variable costs. The total annual variable costs are divided by the annual number of miles the Company aircraft flew to derive an average variable cost per mile. This average variable cost per mile is then multiplied by the miles flown for personal use. Incremental costs do not include fixed costs that do not change based on usage, such as pilots' salaries, the purchase costs of Company-owned aircraft, insurance, scheduled maintenance and non-trip related hangar expenses. Messrs. Diller and Levin occasionally had family members or other guests accompany them on business and personal trips. While travel by family members or other guests does not result in any incremental cost to the Company, such travel does result in the imputation of taxable income to Messrs. Diller and Levin, the amount of which is calculated in accordance with applicable Internal Revenue Service rules.

(b)

Reflects $145,359 paid to or on behalf of Mr. Schiffman for certain costs related to the relocation of him and his family to the New York City metropolitan area and $80,227 in related tax reimbursements on income imputed to Mr. Schiffman for certain of these costs.

(c)

Represents the total amount of other benefits provided to Mr. Diller, none of which individually exceeded 10% of the total value of all perquisites and personal benefits. The total amount of other benefits provided reflects: (i) lease payments, parking, fuel, maintenance and other costs associated with Mr. Diller's personal use of an automobile leased and maintained by IAC and a cash car allowance, (ii) an allocation (based on square footage) of costs for the use of IAC office space by certain individuals who work for Mr. Diller personally, (iii) an allocation (based on the number of personal computers and communication devices supported by IAC) of costs relating to the use by such individuals of the Company's information technology technical support and certain communications equipment and (iv) costs incurred for Mr. Diller's personal use of other car services.

In connection with the grant of IAC stock options to Mr. Levin at the time he was appointed Chief Executive Officer of IAC in June 2015, Mr. Levin surrendered equity awards tied solely to the value of IAC's Search business.

(1)

These stock options vested/vest in four equal installments on the anniversary of the applicable grant date, subject to continued employment.

(2)

The exercise price is equal to the fair market value per share (as defined in the applicable stock and annual incentive plan) of IAC common stock on the grant date.

(3)

Reflects the grant date fair value of stock option awards using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, including expected volatility (based on the historical volatility of IAC common stock), risk-free interest rates (based on U.S. Treasury yields for notes with terms comparable to those of the stock options, in effect at the grant date), expected term (based on the historical exercise behavior of our employees) and dividend yield (based on historical dividend payments). The assumptions used to calculate the amounts in the table above for stock option awards granted to our named executives are as follows:        

Named Executive	Expected Volatility			Risk-Free Interest Rate			Expected Term	Dividend Yield
Joseph Levin		30.27	%		1.317	%	6.07 years		—
Glenn H. Schiffman		30.18	%		1.333	%	6.16 years		—

2016 Option Exercises and Stock Vested

        The table below provides information regarding the number of shares acquired by our named executives upon the exercise of stock options and/or the vesting of RSU awards in 2016 and the related value realized, excluding the effect of any applicable taxes. The dollar value realized upon the exercise of stock options represents the difference between the sale price of the shares acquired upon exercise and the exercise price of the stock options, multiplied by the number of stock options exercised. The dollar value realized upon the vesting of RSUs represents the closing price of IAC common stock on the vesting date, multiplied by the number of RSUs so vesting.

Estimated Potential Payments Upon Termination or Change in Control of IAC

        Certain of our employment agreements, equity award agreements and/or omnibus stock and annual incentive plans entitle our named executives to continued base salary payments, the acceleration of the vesting of equity awards and/or extended post-termination exercise periods for stock options upon certain terminations of employment (including certain terminations during specified periods following a change in control of IAC). These arrangements are described below as they would have applied to each named executive on December 31, 2016.

        Certain amounts that would have become payable to our named executives upon the events described above (as and if applicable), assuming that the relevant event occurred on December 31, 2016, are described and quantified in the table below. These amounts, which exclude the effect of any applicable taxes, are based on the named executive's base salary and the number of IAC stock options and/or RSUs outstanding on December 31, 2016 and the closing price of IAC common stock ($64.79) on December 30, 2016. In addition to these amounts, certain other amounts and benefits generally payable and made available to other Company employees upon a termination of employment, including payments for accrued vacation time and outplacement services, will generally be payable to named executives.

Messrs. Diller, Levin and Stein

        No payments would have been made to Messrs. Diller, Levin and Stein pursuant to any agreement between the Company and these named executives upon a termination without cause or due to death or disability or a resignation for good reason on December 31, 2016. In addition, no payments would have been made to Messrs. Diller, Levin and Stein pursuant to any agreement between the Company and these named executives upon a change in control of IAC on December 31, 2016. Lastly, upon a termination without cause or resignation for good reason on December 31, 2016 that occurred during the two (2) year period following a change in control of IAC, in accordance with the applicable omnibus stock and incentive plan and the related award agreements, the vesting of all then outstanding and unvested stock options and/or RSUs, as applicable, held by Messrs. Diller, Levin and Stein would have been accelerated.

34

        In addition, in the case of Mr. Diller only, under the Equity and Bonus Compensation Agreement, dated August 24, 1995, between the Company and Mr. Diller, we agreed that to the extent any payment or distribution by the Company to or for the benefit of Mr. Diller (whether under the terms of the related agreement or otherwise) would be subject to the excise tax imposed by §4999 of the Internal Revenue Code, or any interest or penalties are incurred by Mr. Diller with respect to such excise tax, then Mr. Diller would be entitled to a gross-up payment covering the excise taxes and related interest and penalties. Given that Mr. Diller would not have received any payments or other benefits upon an assumed change in control of IAC at the end of 2016, the Company does not believe that any excise tax would be imposed or that any gross-up would be required.

Mr. Kaufman

        Upon a termination without cause or resignation for good reason on December 31, 2016, pursuant to the terms of his employment agreement, Mr. Kaufman would have been entitled to:

•

the partial vesting of outstanding and unvested RSUs in amounts equal to the number that would have otherwise vested in accordance with the terms of such awards during the 12-month period following such termination of employment; and

•

Information excludes 3,941,292 shares that may be issuable upon the settlement of subsidiary-level equity awards (after giving effect to the withholding of shares to cover taxes due) that relate to subsidiaries of IAC and Match Group, Inc. ("Match Group"), based on the estimated values of such awards as of December 31, 2016. For a description of these awards, see the discussion under

38

the caption "Equity Instruments Denominated in the Shares of Certain Subsidiaries" in Note 13 to the consolidated financial statements in our Form 10-K for the fiscal year ended December 31, 2016, which is incorporated herein by reference.

Following the completion of Match Group's initial public offering in November 2015, subsidiary-level equity awards that relate to Match Group subsidiaries are settleable, at IAC's election, in shares of IAC common stock or Match Group common stock. To the extent that shares of IAC common stock are issued in settlement of these awards, Match Group will reimburse IAC for the cost of those shares by issuing IAC additional shares of Match Group common stock.


The number of shares ultimately needed to settle subsidiary-level equity awards can vary from the estimated numbers disclosed above as a result of both movements in our stock price and determinations of the fair value of the relevant subsidiaries that differ from our estimated determinations of the fair value of such subsidiaries as of December 31, 2016.

DIRECTOR COMPENSATION

        Non-Employee Director Compensation Arrangements.    The Nominating Committee has primary responsibility for establishing non-employee director compensation arrangements, which have been designed to provide competitive compensation necessary to attract and retain high quality non-employee directors and to encourage ownership of Company stock to further align the interests of our directors with those of our stockholders. Arrangements in effect during 2016 provided that: (i) each member of the Board receive an annual retainer in the amount of $50,000, (ii) each member of the Audit and Compensation and Human Resources Committees (including their respective Chairpersons) receive an additional annual retainer in the amount of $10,000 and $5,000, respectively, and (iii) the Chairpersons of each of the Audit and Compensation and Human Resources Committees receive an additional annual Chairperson retainer in the amount of $20,000, with all amounts being paid quarterly, in arrears.

        In addition, these arrangements also provided that each non-employee director receive a grant of RSUs with a dollar value of $250,000 upon his or her initial election to the Board and annually thereafter upon re-election on the date of IAC's annual meeting of stockholders, the terms of which provide for: (i) vesting in three equal installments commencing on the anniversary of the grant date, (ii) cancellation and forfeiture of unvested RSUs in their entirety upon termination of Board service for IAC and its affiliates and (iii) full acceleration of vesting upon a change in control of IAC. The Company also reimburses non-employee directors for all reasonable expenses incurred in connection with attendance at IAC Board and Board committee meetings.

39

        Deferred Compensation Plan for Non-Employee Directors.    Under IAC's Deferred Compensation Plan for Non-Employee Directors, non-employee directors may defer all or a portion of their Board and Board committee fees. Eligible directors who defer all or any portion of these fees can elect to have such deferred fees applied to the purchase of share units, representing the number of shares of IAC common stock that could have been purchased on the relevant date, or credited to a cash fund. If any dividends are paid on IAC common stock, dividend equivalents will be credited on the share units. The cash fund will be credited with deemed interest at an annual rate equal to the weighted average prime lending rate of JPMorgan Chase & Co. After a director ceases to be a member of the Board, he or she will receive: (i) with respect to share units, such number of shares of IAC common stock as the share units represent, and (ii) with respect to the cash fund, a cash payment in an amount equal to deferred amounts, plus accrued interest. These payments are generally made in a one lump sum installment after the relevant director leaves the Board and otherwise in accordance with the plan.

        2016 Non-Employee Director Compensation.    The table below provides the amount of: (i) fees earned by non-employee directors for services performed during 2016 (excluding the effect of any applicable taxes) and (ii) the grant date fair value of RSU awards granted in 2016.

(1)

Represents the dollar value of fees deferred in the form of share units by the relevant director under IAC's Deferred Compensation Plan for Non-Employee Directors. Pursuant to the terms of the plan, share units are credited with the number of share units that could have been purchased with the dollar amount of ordinary cash dividends payable on the number of share units outstanding on the relevant dividend record date, with each share unit being treated as if it was one share of IAC common stock. Share units issued as credit for ordinary cash dividends paid are settled at the same time as the underlying share units (after the relevant director leaves the Board and otherwise in accordance with the plan).

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires the Company's directors and certain of the Company's officers, and persons who beneficially own more than 10% of a registered class of the Company's equity securities, to file initial statements of beneficial ownership (Form 3) and statements of changes in beneficial ownership (Forms 4 and 5) of IAC common stock and other equity securities of the Company with the SEC. Officers, directors and greater than 10% beneficial owners are required by SEC rules to furnish the Company with copies of all such forms they file. Based solely on a review of the copies of such forms furnished to the Company and/or written representations that no additional forms were required, the Company believes that its officers, directors and greater than 10% beneficial owners complied with these filing requirements in 2016.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Review of Related Person Transactions

        The Audit Committee has a formal, written policy that requires an appropriate review of all related person transactions by the Audit Committee, as required by Marketplace Rules governing conflict of interest transactions. For purposes of this policy, as amended, consistent with the Marketplace Rules, the terms "related person" and "transaction" are determined by reference to Item 404(a) of Regulation S-K under the Securities Act of 1933, as amended ("Item 404"). During 2016, in accordance with this policy, Company management was required to determine whether any proposed transaction, arrangement or relationship with a related person fell within the definition of "transaction" set forth in Item 404, and if so, review such transaction with the Audit Committee. In connection with such determinations, Company management and the Audit Committee consider: (i) the parties to the transaction and the nature of their affiliation with IAC and the related person, (ii) the dollar amount involved in the transaction, (iii) the material terms of the transaction, including whether the terms of the transaction are ordinary course and/or otherwise negotiated at arms' length, (iv) whether the transaction is material, on a quantitative and/or qualitative basis, to IAC and/or the related person and (v) any other facts and circumstances that Company management or the Audit Committee deems appropriate.

Relationships Involving Significant Stockholders, Named Executives and Directors

        Relationships Involving Mr. Diller.    Pursuant to an amended and restated governance agreement between IAC and Mr. Diller, for so long as Mr. Diller serves as IAC's Chairman and Senior Executive, he currently generally has the right to consent to limited matters in the event that IAC's ratio of total debt to EBITDA (as defined in the governance agreement) equals or exceeds four to one over a continuous twelve-month period.

44

        However, upon the effectiveness of the Class C Issuance (as described below), a new governance agreement will eliminate these consent rights. As part of the new governance agreement, Mr. Diller and certain of his family members (and his and their affiliates) have agreed to certain transfer restrictions with respect to any Class C common stock issued to them and have further agreed that they will not enter into certain transactions unless such transactions include the same consideration, or an offer to receive the same consideration to all holders of shares of IAC's capital stock, subject to certain important exceptions. For a description of the rights provided in the new governance agreement, see the disclosure in the proxy statement relating to our 2016 Annual Meeting of Stockholders set forth under the caption "Second Amended and Restated Governance Agreement" under "Proposal 3—Approval of the Adoption of IAC's Amended and Restated Certificate of Incorporation,"which disclosure is incorporated by reference herein.

        At IAC's 2016 Annual Meeting of Stockholders, our stockholders approved the creation of a new class of non-voting, Class C common stock (the "Class C Issuance"). Despite this approval, the Company has agreed not to effect the Class C Issuance during the pendency of the lawsuit described in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2016 under the caption "Item 3—Legal Proceedings—Delaware Law Class Action Litigation," which disclosure is incorporated herein by reference.

        As discussed in the Compensation Discussion and Analysis on page 27, pursuant to the Company's Airplane Travel Policy, Mr. Diller is required to travel by Company-owned or chartered aircraft for both business and personal use. Mr. Diller reimbursed IAC approximately $175,000 for personal use of Company-owned aircraft in 2016.

        Relationships Involving Other Directors.    In June 2010, Mr. Bronfman was part of a trial in the Trial Court in Paris involving six other individuals, including the former Chief Executive Officer, Chief Financial Officer and Chief Operating Officer of Vivendi Universal. The other individuals faced various criminal charges and civil claims relating to Vivendi, including Vivendi's financial disclosures, the appropriateness of executive compensation and trading in Vivendi stock. Mr. Bronfman previously served as the Vice Chairman of Vivendi and faced a charge and claims relating to certain trading in Vivendi stock in January 2002. At the trial, the public prosecutor and the lead civil claimant both took the position that Mr. Bronfman should be acquitted. In January 2011, the court found Mr. Bronfman guilty of the charge relating to his trading in Vivendi stock, found him not liable to the civil claimants and imposed a fine of 5 million euros and a suspended sentence of fifteen months. Mr. Bronfman appealed the Trial Court decision to the Paris Court of Appeal. In November 2013, Mr. Bronfman participated in a re-trial before a new judicial panel as part of his appeal of the Paris Trial Court's 2011 ruling. In May 2014, the new judicial panel rendered its decision, affirming the Paris Trial Court's finding that Mr. Bronfman was guilty of the charge, but stated that its finding would appear only in French judicial records (and not in Mr. Bronfman's public record), removed the suspended sentence imposed by the Paris Trial Court and suspended 2.5 million euros of the original fine of 5 million euros. The new judicial panel affirmed the Paris Trial Court's finding that Mr. Bronfman was not liable to the civil claimants. Mr. Bronfman appealed the verdict. On April 20, 2016, the Appellate Court rejected the appeal. Mr. Bronfman believes that his trading in Vivendi stock was proper and has the option of pursuing a challenge to the Appellate Court's decision before the European Court of Human Rights.

Relationships Involving IAC and Expedia

        Overview.    Since the completion of the spin-off of Expedia in August 2005 (the "Expedia Spin-Off"), IAC and Expedia have been related parties since they are under common control. In connection with and following the Expedia Spin-Off, IAC and Expedia entered into certain arrangements, including arrangements regarding the sharing of certain costs, the use and ownership of certain aircraft and various commercial agreements, certain of which are generally described below.

45

        Cost Sharing Arrangements.    Mr. Diller currently serves as Chairman and Senior Executive of both IAC and Expedia. In connection with the Expedia Spin-Off, IAC and Expedia had agreed, in light of Mr. Diller's senior role at both companies and his anticipated use of certain resources to the benefit of both companies, to share certain expenses associated with such usage, as well as certain costs incurred by IAC in connection with the provision of certain benefits to Mr. Diller (the "Shared Costs"). Cost sharing arrangements in effect during 2016 provided that each of IAC and Expedia cover 50% of the Shared Costs, which both companies agreed best reflects the allocation of actual time spent (and time to be spent) by Mr. Diller between the two companies. Shared Costs include costs for personal use of cars and equipment dedicated to Mr. Diller's use and expenses relating to Mr. Diller's support staff. Costs in 2016 for which IAC billed Expedia were approximately $516,000 pursuant to these arrangements.

        Aircraft Arrangements.    Each of IAC and Expedia has a 50% ownership interest in two aircraft that may be used by both companies (the "Aircraft"). IAC and Expedia entered into an amended and restated operating agreement that allocates the costs of operating and maintaining the Aircraft between the parties. Fixed costs are allocated 50% to each company and variable costs are allocated based on usage. These costs are generally paid by each company to third parties in accordance with the terms of the amended and restated operating agreement.

        In the event Mr. Diller ceases to serve as Chairman of either IAC or Expedia, each of IAC and Expedia will have a put right (to the other party) with respect to its owned interest in the aircraft that it does not primarily use (with such determination to be based on relative usage over the twelve months preceding such event), in each case, at fair market value for the relevant aircraft.

        Members of the flight crew for the Aircraft are employed by an entity in which each of IAC and Expedia has a 50% ownership interest. IAC and Expedia have agreed to share costs relating to flight crew compensation and benefits pro-rata according to each company's respective usage of the Aircraft, for which they are separately billed by the entity described above. During 2016, total payments in the amount of approximately $2.4 million were made to this entity by IAC.

        On April 13, 2017, each of IAC and Expedia paid 50% of the $29.8 million in total costs (purchase price and related costs) for an additional aircraft in which each company has a 50% ownership interest. This aircraft is expected to replace the older of the companies' two existing jointly-owned aircraft and be available for use by both companies in the third quarter of 2017.

        Commercial Agreements.    In connection with and following the Expedia Spin-Off, certain IAC businesses entered into commercial agreements with certain Expedia businesses. IAC believes that these arrangements are ordinary course and have been negotiated at arm's length. In addition, IAC believes that none of these arrangements, whether taken individually or in the aggregate, constitute a material contract to IAC. None of these arrangements, whether taken individually or together with other similar agreements, involved payments to or from IAC and its businesses in excess of $120,000 in 2016.

ANNUAL REPORTS

        Upon written request to the Corporate Secretary, IAC/InterActiveCorp, 555 West 18th Street, New York, New York 10011, IAC will provide without charge to each person solicited a printed copy of IAC's 2016 Annual Report on Form 10-K, including the financial statements and financial statement schedule filed therewith. Copies are also available on our website, www.iac.com. IAC will furnish requesting stockholders with any exhibit to its 2016 Annual Report on Form 10-K upon payment of a reasonable fee.

STOCKHOLDER PROPOSALS AND DIRECTOR NOMINEES FOR PRESENTATION
AT THE 2018 ANNUAL MEETING

        Eligible stockholders who intend to have a proposal considered for inclusion in IAC's proxy materials for presentation at the 2018 Annual Meeting of Stockholders pursuant to Rule 14a-8 under the Exchange Act must submit such proposal to IAC at its corporate headquarters no later than January 10, 2018. Stockholder proposals submitted for inclusion in IAC's proxy materials must be made in accordance with the provisions of Rule 14a-8 of the Exchange Act. Eligible stockholders who intend to present a proposal or nomination at the 2018 Annual Meeting of Stockholders without inclusion of the proposal in IAC's proxy materials are required to provide notice of such proposal or nomination to IAC at its corporate headquarters no later than March 26, 2018. If IAC does not receive notice of the proposal or nomination at its corporate headquarters prior to such date, such proposal or nomination will be considered untimely for purposes of Rules 14a-4 and 14a-5 of the Exchange Act and those IAC officers who have been designated as proxies will accordingly be authorized to exercise discretionary voting authority to vote for or against the proposal. IAC reserves the right to reject, rule out of order or take other appropriate action with respect to any proposal or nomination that does not comply with these and other applicable requirements.

47

HOUSEHOLDING

        The SEC has adopted rules that permit companies and intermediaries (such as brokers) to send one set of Notice or printed proxy materials, as applicable, to any household at which two or more stockholders reside if they appear to be members of the same family or have given their written consent (each stockholder continues to receive a separate proxy card). This process, which is commonly referred to as "householding," reduces the number of duplicate copies of materials stockholders receive and reduces printing and mailing costs. Only one Notice or one set of printed proxy materials, as applicable, will be sent to stockholders eligible for householding unless contrary instructions have been provided.

        Once you have received notice that your broker or IAC will be householding your materials, householding will continue until you are notified otherwise or you revoke your consent. You may request a separate Notice or set of printed proxy materials by sending a written request to Investor Relations, IAC/InterActiveCorp, 555 West 18th Street, New York, New York 10011, by calling 1.212.314.7400 or by e-mailing ir@iac.com. Upon request, IAC undertakes to deliver such materials promptly.

        If at any time: (i) you no longer wish to participate in householding and would prefer to receive a separate Notice or set of our printed proxy materials, as applicable, or (ii) you and another stockholder sharing the same address wish to participate in householding and prefer to receive one Notice or set of our printed proxy materials, as applicable, please notify your broker if you hold your shares in street name or IAC if you are a stockholder of record. You can notify us by sending a written request to Investor Relations, IAC/InterActiveCorp, 555 West 18th Street, New York, New York 10011, by calling 1.212.314.7400 or by e-mailing ir@iac.com.

NOTICE OF INTERNET AVAILABILITY OF PROXY MATERIALS

        In fulfilling its purpose, the Audit Committee shall maintain free and open communication between the Committee, the independent accounting firm, the internal auditors and management of the Company.

LIMITATION OF AUDIT COMMITTEE'S ROLE

These are the responsibilities of management and the independent accounting firm. Additionally, the Audit Committee as well as the Board recognizes that members of the Company's management who are responsible for financial management, as well as the independent accounting firm, have more time, knowledge, and detailed information on the Company than do Committee members; consequently, in carrying out its oversight responsibilities, the Audit Committee is not providing any expert or special assurances with respect to the Company's financial statements or any professional certifications as to the independent accounting firm's work.
