NOTICE OF SPECIAL MEETING OF STOCKHOLDERS OF IAC/INTERACTIVECORP
TO BE HELD ON [], 2021

To the Stockholders of IAC/InterActiveCorp:

IAC/InterActiveCorp (which we refer to as “IAC”) is making this proxy statement/consent solicitation statement/prospectus available to holders of IAC’s common stock and Class B common stock in connection with the solicitation of proxies by the board of directors of IAC for use at the special meeting of IAC stockholders to be held on [·], [·], 2021 at [·] Eastern Time (which we refer to as the “special meeting”). The special meeting will be a virtual meeting, conducted solely online. Stockholders will be able to attend the special meeting by visiting [·].

At the special meeting, IAC stockholders will consider the separation of IAC’s Vimeo business from the remaining businesses of IAC through a series of transactions (which we refer to as the “Spin-off”) that will result in the pre-transaction stockholders of IAC directly owning shares in both IAC and SpinCo, and in SpinCo becoming a public company. In particular, IAC will ask its stockholders:

This proxy statement/consent solicitation statement/prospectus refers to the foregoing proposal as the “Spin-off Proposal”;

Approval of the Spin-off Proposal, which is a condition to the completion of the Spin-off, requires (i) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC common stock entitled to vote on such matter, voting as a separate class; (ii) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC Class B common stock entitled to vote on such matter, voting as a separate class; (iii) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC capital stock entitled to vote on such matter, voting together as a single class and (iv) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC common stock entitled to vote on the proposal, other than any shares of IAC common stock owned, directly or indirectly, by the members of the IAC board of directors, any person that IAC has determined to be an “officer” of IAC within the meaning of Rule 16a-1(f) of the Securities Exchange Act of 1934, as amended (which we refer to as the “Exchange Act”), and the immediate family members of any of the foregoing.

Approval of the Corporate Opportunities Proposal requires the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC capital stock entitled to vote on such matter, voting together as a single class. Assuming that a quorum is present, the affirmative vote of a majority of the voting power of the shares present in person or represented by proxy and entitled to vote on the matter is required to approve the Adjournment Proposal.

The IAC board of directors has set [·], 2021 as the record date for the special meeting. This means that holders of record of IAC common stock and IAC Class B common stock at the close of business on that date are entitled to receive notice of the special meeting and to vote their shares at the special meeting and any related adjournments or postponements.

Only IAC stockholders and persons holding proxies from IAC stockholders may attend the special meeting. To participate in the special meeting online at [·] you will need the 16-digit control number included on your proxy card or the instructions that accompanied your proxy materials. A list of IAC stockholders entitled to vote at the special meeting will be available at [·] for examination by any IAC stockholder at the special meeting.

THE IAC BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” EACH PROPOSAL TO BE PRESENTED AT THE IAC SPECIAL MEETING.

The above matters are more fully described in the accompanying proxy statement/consent solicitation statement/prospectus.

VIMEO, INC.

555 West 18th Street

New York, New York 10011

NOTICE OF SOLICITATION OF WRITTEN CONSENT

To the holders of Class A Voting Common Stock of Vimeo, Inc.:

Pursuant to an Agreement and Plan of Merger, dated as of December 23, 2020 (which we refer to as the “Vimeo merger agreement”) by and among Vimeo Holdings, Inc. a Delaware corporation and a wholly owned subsidiary of IAC (“SpinCo”), Stream Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of SpinCo (which we refer to as “Merger Sub”), and Vimeo, Inc. (which we refer to as “Vimeo”), Merger Sub will be merged with and into Vimeo, with Vimeo continuing as the surviving company and a subsidiary of SpinCo (which we refer to as the “Vimeo merger”).

The per share merger consideration in the Vimeo merger will be a number of shares of SpinCo common stock calculated pursuant to a formula, which we refer to as the Vimeo merger exchange ratio. The components of the Vimeo merger exchange ratio and the method by which it will be calculated are described in this proxy statement/consent solicitation statement/prospectus and set forth in the Vimeo merger agreement, which is attached as Annex G to this proxy statement/consent solicitation statement/prospectus. See the section of this proxy statement/consent solicitation statement/prospectus entitled “The Vimeo Merger — Consideration to Vimeo Stockholders” for a description of the formula that will be used to calculate the Vimeo merger exchange ratio, and the Vimeo merger agreement attached as Annex G to this proxy statement/ consent solicitation statement/prospectus.

The accompanying consent solicitation statement, which also constitutes a prospectus of SpinCo with respect to the shares of SpinCo common stock to be issued in the Vimeo merger, and separately constitutes a proxy statement of IAC in connection with the proposals required to implement the Spin-off and a prospectus of IAC and of SpinCo with respect to the shares of their respective capital stock to be issued in connection with the Spin-off, is being delivered to you on behalf of the board of directors of Vimeo to request that Vimeo stockholders as of the record date of [·], 2021 approve the adoption of the Vimeo merger agreement by executing and returning the written consent furnished with the accompanying proxy statement/ consent solicitation statement/prospectus.

The accompanying proxy statement/consent solicitation statement/prospectus describes the Vimeo merger agreement, the Vimeo merger and the actions to be taken in connection with the Vimeo merger agreement, the Vimeo merger and the related transactions, and provides additional information about the parties. A copy of the Vimeo merger agreement is attached as Annex G to this proxy statement/consent solicitation statement/prospectus.

A summary of the appraisal rights that may be available to you as a Vimeo stockholder is described in the section of the accompanying proxy statement/consent solicitation statement/prospectus entitled “The Consent Solicitation — Appraisal Rights,” beginning on page 82 of this proxy statement/consent solicitation statement/prospectus. It is a condition to SpinCo’s obligation to consummate the Vimeo merger that at least 20 days have passed since delivery of the required notice of appraisal rights to Vimeo stockholders and that no Vimeo stockholder has asserted appraisal rights that have not been waived or abandoned. If any Vimeo stockholder asserts appraisal rights in connection with the Vimeo merger, the parties to the Vimeo merger agreement anticipate that the Vimeo merger will not be consummated and that they would pursue another option to cause or permit the existing stockholders of Vimeo to exchange their interest in Vimeo for an interest in SpinCo. Please note that if you wish to exercise appraisal rights, you must not sign and return a written consent approving the adoption of the Vimeo merger agreement. However, so long as you do not return a written consent at all, it is not necessary to affirmatively vote against or disapprove the adoption of the Vimeo merger agreement. In addition, you must take all other steps necessary to perfect your appraisal rights.

The Vimeo board of directors has considered the Vimeo merger and the terms of the Vimeo merger agreement and unanimously approved and declared advisable the Vimeo merger agreement and the Vimeo merger.

Please complete, date and sign the written consent furnished with the accompanying proxy statement/ consent solicitation statement/prospectus and return it promptly to Vimeo by one of the means described in the section entitled

“The Consent Solicitation — Submission of Written Consents,” beginning on page 66 of the accompanying proxy statement/consent solicitation statement/prospectus.

Questions and Answers about the Merger and the Spin-off

​

Questions and Answers about the Special Meeting

This proxy statement/consent solicitation statement/prospectus refers to the foregoing proposal as the “Spin-off Proposal”;

For a discussion of the factors that the IAC board of directors considered in determining to recommend in favor of the Spin-off Proposal, the Corporate Opportunities Proposal and the Adjournment Proposal, see the section of this proxy statement/consent solicitation statement/prospectus entitled “The Spin-off — Reasons for the Spin-off; Recommendation of the IAC Board of Directors.”

If other matters are properly presented at the special meeting for consideration, the three IAC officers who have been designated as proxies for the special meeting, Kendall F. Handler, Joanne Hawkins and Glenn H. Schiffman, will have the discretion to vote on those matters for stockholders who have submitted their proxy.

As of the close of business on the special meeting record date, there were [·] shares of IAC common stock and 5,789,499 shares of IAC Class B common stock outstanding and entitled to vote at the special meeting. Holders of

IAC common stock are entitled to one vote per share and holders of IAC Class B common stock are entitled to ten votes per share.

You may examine a list of the stockholders of record as of the close of business on [·], 2021 for any purpose germane to the special meeting, subject to compliance with applicable provisions of Delaware law, during normal business hours during the 10-day period preceding the date of the special meeting at IAC’s corporate headquarters, located at 555 West 18th Street, New York, New York 10011.

You may also participate in the special meeting online at [·] and vote your shares of IAC capital stock online at that time, even if you have previously submitted your vote. To do so, you will need the sixteen- digit control number included on your proxy card or the instructions that accompanied your proxy materials.

For IAC shares stock held in street name, holders may submit a proxy online or by telephone before the date of the special meeting if their broker, bank and/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 and/or other holder of record. If you hold your shares through a broker, bank and/or other holder of record, follow the voting instructions you receive from your broker, bank and/or other holder of record.

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 outstanding shares or the number of shares present at the special meeting 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. Accordingly, an abstention will have the same effect as a vote “AGAINST” each of the proposals submitted for consideration at the special meeting.

A broker non-vote will result if your broker, bank or other nominee returns a proxy but does not provide instruction as to how shares should be voted on a particular matter. If any broker non-votes occur, shares represented by broker non-votes are not treated as shares present and able to be voted. Accordingly, a broker non-vote will not count as present for purposes of determining a quorum, and:

To change your vote or revoke your proxy, follow the instructions provided on the proxy card to do so online or by telephone, or send a written notice or a new proxy card to [·]. You may request a new proxy card by calling IAC’s proxy solicitor, Georgeson, at 1-800-891-3214.

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.

In addition to solicitations by mail, directors, officers and employees of IAC may solicit proxies from stockholders by telephone, letter, facsimile, email or in person.

In addition, IAC has retained Georgeson to distribute proxy solicitation materials to brokers, banks and other holders of record and to assist in the solicitation of proxies from IAC stockholders. The fee for such firm’s services is estimated to be approximately $[·], plus reimbursement for their reasonable out-of-pocket expenses.

Following the initial mailing of the 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 capital 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.

Questions and Answers About the Spin-off

IAC’s Vimeo business to SpinCo, SpinCo becoming an independent, separately traded public company through a spin-off from IAC, and Vimeo, the IAC subsidiary that currently holds the Vimeo business, becoming a wholly-owned subsidiary of SpinCo.

If the Spin-off is effected and the Vimeo merger is completed, the holders of shares of IAC capital stock outstanding immediately prior to the Spin-off will continue to own all of the outstanding shares IAC capital stock, and will become the direct owners of a percentage of the outstanding shares of SpinCo capital stock approximately equal, in the aggregate, to IAC’s indirect ownership interest in Vimeo prior to the Spin-off. The remaining shares of SpinCo’s outstanding capital stock will, if the Vimeo merger is completed, be owned by Vimeo’s pre-separation third-party stockholders. If the Spin-off is completed but the Vimeo merger is not completed, the shares of SpinCo capital stock issued to IAC stockholders in the Spin-off will initially constitute all of the outstanding shares of SpinCo capital stock immediately following the consummation of the Spin-off, Vimeo’s pre-separation third-party stockholders will initially remain stockholders of Vimeo, and SpinCo will own approximately 88% of Vimeo’s outstanding shares. SpinCo anticipates that it would subsequently seek to implement an alternative transaction to cause or permit the stockholders of Vimeo to exchange their ownership interests in Vimeo for an interest in SpinCo.

For further information about SpinCo after the Spin-off, please see the section of this proxy statement/ consent solicitation statement/prospectus entitled “Information About SpinCo After the Spin-off.” For further information about IAC after the Spin-off, please see the section of this proxy statement/ consent solicitation statement/prospectus entitled “Information About IAC After the Spin-off.”

For a discussion of the factors that the IAC board of directors considered in determining to proceed with the Spin-off, please see the section of this proxy statement/consent solicitation statement/prospectus entitled “The Spin-off — Reasons for the Spin-off; Recommendation of the IAC Board of Directors.”

As a result of the Spin-off, holders of shares of IAC capital stock will, immediately after the completion of the Spin-off, own approximately 88% of the outstanding capital stock of SpinCo. This ownership percentage will be subject to change based on the anti-dilution adjustment described in the section of this proxy statement/consent solicitation statement/prospectus entitled “The Vimeo Merger — Consideration to Vimeo Stockholders,” and will not be known until the completion of the Spin-off.

For more information, please see the section of this proxy statement/consent solicitation statement/prospectus entitled “The Spin-off — Structure of the Spin-off.”

but before the special meeting, you will, unless the transferee requests a proxy from you, retain your right to vote at the special meeting but will transfer the right to receive shares (and any cash in lieu of fractional shares) to which you would otherwise be entitled in connection with the Spin-off to the person to whom you transfer your shares. In order to receive the shares (and any cash in lieu of fractional shares) which you are entitled to receive in connection with the Spin-off as an IAC stockholder, you must hold your shares through the completion of the Spin-off.

Questions and Answers About the Vimeo Merger and the Consent Solicitation

See the sections entitled “The Vimeo Merger” and “The Vimeo Merger Agreement.”

See the sections entitled “The Vimeo Merger Agreement — Conditions to the Completion of the Vimeo Merger” and “The Vimeo Merger Agreement — Termination of the Vimeo Merger Agreement.”

To exercise appraisal rights, Vimeo stockholders must strictly comply with the procedures prescribed by Delaware law. These procedures are summarized in the section entitled “The Consent Solicitation — Appraisal Rights.” Failure to strictly comply with these provisions will result in a loss of appraisal rights.

It is a condition to SpinCo’s obligation to complete the Vimeo merger that at least 20 days have passed since delivery of the required notice of appraisal rights and that no Vimeo stockholder has asserted appraisal rights that have not been waived or abandoned.

The Vimeo merger exchange ratio will be calculated pursuant to a formula, as further described in this proxy statement/consent solicitation statement/prospectus.

For more information, please see the section of this proxy statement/consent solicitation statement/ prospectus entitled “The Vimeo Merger — Consideration to Vimeo Stockholders.”

A: The Vimeo board of directors unanimously recommends that Vimeo stockholders approve the Vimeo merger agreement proposal by executing and returning the written consent furnished with this proxy statement/consent solicitation statement/prospectus.

As of the written consent record date, a subsidiary of IAC owns approximately 88% of the outstanding shares of Vimeo capital stock, including approximately 81% of the outstanding shares of Vimeo voting common stock, and intends to deliver a consent to the Vimeo merger proposal. The remaining approximately 19% of the outstanding shares of Vimeo voting common stock are owned by third- party investors.

RISK FACTORS

You should carefully consider each of the following risks and uncertainties associated with IAC and the ownership of IAC securities and with SpinCo and the ownership of SpinCo securities. In addition, for more information you should review the specific descriptions of each of IAC’s and SpinCo’s businesses under “Information About IAC After the Spin-off” and “Information About SpinCo After the Spin-off” in this proxy statement/consent solicitation statement/prospectus as well as other information incorporated by reference into this proxy statement/consent solicitation statement/prospectus.

Risks Relating to the Spin-off

The parties may be unable to achieve some or all of the benefits that they expect to achieve through the Spin- off.

The parties to the Spin-off may be unable to achieve the full strategic and financial benefits expected to result from the Spin-off, or such benefits may be delayed or may never occur at all. The Spin-off is expected to provide the following benefits, among others:

The parties may not achieve these or other anticipated benefits for a variety of reasons, including, among others: (a) the possibility that the Spin-off will be abandoned prior to completion, or will otherwise not be completed, (b) the possibility that IAC’s non-Vimeo businesses will not be successful, and that IAC will not succeed in identifying new profitable acquisitions or other opportunities or in developing its existing businesses, (c) the fact that IAC and SpinCo will be more susceptible to market fluctuations and other adverse events following the consummation of the Spin-off, (d) the risk of litigation, injunctions or other legal proceedings relating to the Spin-off, (e) the Spin-off will require significant amounts of management time and effort, which may divert management attention from operating and growing IAC’s and Vimeo’s respective businesses and (f) the other actions required to separate IAC’s and Vimeo’s respective businesses prior to closing could disrupt IAC’s and Vimeo’s respective operations. If the parties fail to achieve some or all of the benefits expected to result from the Spin-off, or if such benefits are delayed, IAC’s or SpinCo’s business, financial condition and results of operations of IAC and/or SpinCo could be materially and adversely affected.

Following the Spin-off, the financial profile of each of IAC and SpinCo will change, and each will be a smaller, less diversified company than IAC prior to the Spin-off.

The Spin-off will result in each of IAC and SpinCo being smaller, less diversified companies with more limited businesses, which in SpinCo’s case will be concentrated in its industry, than IAC prior to the Spin- off. As a result, each

of IAC and SpinCo may be more vulnerable to changing market conditions, which could have a material adverse effect on their respective business, financial condition and results of operations and may subject them to increased volatility.

If the Spin-off were to fail to qualify as a transaction that is generally tax-free for U.S. federal income tax purposes, IAC, SpinCo and their respective stockholders could suffer material adverse consequences.

It is a condition to the completion of the Spin-off that IAC receives an opinion of IAC’s outside counsel, among other things, to the effect that the Spin-off will qualify as a “reorganization” within the meaning of Sections 368(a)(1)(D) and 355(a) of the Code. The opinion of counsel will be based upon and rely on, among other things, various facts and assumptions, as well as certain representations, statements and undertakings of IAC and SpinCo, including those relating to the past and future conduct of IAC and SpinCo. If any of these representations, statements or undertakings is, or becomes, inaccurate or incomplete, or if any of the representations or covenants contained in any of the transaction-related agreements and documents or in any document relating to the opinion of counsel are inaccurate or not complied with by IAC, SpinCo or any of their respective subsidiaries, the opinion of counsel may be invalid and the conclusions reached therein could be jeopardized.

Notwithstanding receipt of the opinion of counsel regarding the Spin-off, the U.S. Internal Revenue Service (the “IRS”) could determine that the Spin-off should be treated as a taxable transaction for U.S. federal income tax purposes if it determines that any of the representations, assumptions or undertakings upon which the opinion of counsel were based are inaccurate or have not been complied with. The opinion of counsel represents the judgment of such counsel and is not binding on the IRS or any court, and the IRS or a court may disagree with the conclusions in the opinion of counsel. Accordingly, notwithstanding receipt by IAC of the opinion of counsel, there can be no assurance that the IRS will not assert that the Spin-off does not qualify for tax-free treatment for U.S. federal income tax purposes or that a court would not sustain such a challenge. In the event the IRS were to prevail with such a challenge, IAC and SpinCo and their respective stockholders could suffer material adverse consequences.

If the Spin-off were to fail to qualify as a transaction that is generally tax-free for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) of the Code, in general, for U.S. federal income tax purposes, IAC would recognize a taxable gain as if it had sold the SpinCo stock in a taxable sale for its fair market value. In such circumstance, IAC stockholders who receive SpinCo common stock in the Spin-off would be subject to tax as if they had received a taxable distribution equal to the fair market value of such shares. Even if the Spin-off were otherwise to qualify as a tax-free transaction under Sections 355(a) and 368(a)(1)(D) of the Code, the Spin-off may result in taxable gain to IAC, but not its stockholders, under Section 355(e) of the Code if the Spin-off were deemed to be part of a plan (or series of related transactions) pursuant to which one or more persons acquire, directly or indirectly, shares representing a 50 percent or greater interest (by vote or value) in IAC or SpinCo. For this purpose, any acquisitions of IAC stock or SpinCo stock within the period beginning two years before, and ending two years after, the Spin-off are presumed to be part of such a plan, although IAC or SpinCo may be able to rebut that presumption (including by qualifying for one or more safe harbors under applicable Treasury Regulations). For further discussion of U.S. federal tax consequences relating to a failure of the Spin-off to qualify for tax-free treatment, see “Material U.S. Federal Income Tax Consequences — The Spin-Off — Material U.S. Federal Income Tax Consequences if the Spin-off is Taxable.” Stockholders of IAC and SpinCo should consult with their own tax advisors regarding the tax consequences of the Spin-off.

In connection with the Spin-off, IAC and SpinCo will enter into a tax matters agreement pursuant to which, among other things, each of IAC and SpinCo will be responsible for certain tax liabilities and obligations following the Spin-off. Under the tax matters agreement, SpinCo will generally be required to indemnify IAC for any taxes resulting from the failure of the Spin-off to qualify for the intended tax-free treatment (and related amounts) to the extent that the failure to so qualify is attributable to (i) an acquisition of all or a portion of the equity securities or assets of SpinCo, whether by merger or otherwise (and regardless of whether SpinCo participated in or otherwise facilitated the acquisition), (ii) other actions or failures to act by SpinCo or (iii) any of the representations or undertakings made by SpinCo in any of the Spin- off related agreements or in the documents relating to the opinion of counsel being incorrect or violated. Any such indemnity obligations could be material. For further discussion of the tax matters agreement, see “Transactions with Related Persons, Promoters and Control Persons — Transactions with Related Persons — Relationship Between IAC and SpinCo After the Spin-Off — Tax Matters Agreement.”

SpinCo may not be able to engage in desirable capital-raising or strategic transactions following the Spin-off.

Under current U.S. federal income tax law, a distribution that otherwise qualifies for tax-free treatment can be rendered taxable to the distributing corporation and its stockholders, as a result of certain post- distribution transactions, including certain acquisitions of shares or assets of the corporation the stock of which is distributed. To preserve the tax-free treatment of the Spin-off, the tax matters agreement will impose certain restrictions on SpinCo and its subsidiaries during the two-year period following the Spin-off (including restrictions on share issuances, business combinations, sales of assets and similar transactions). The tax matters agreement will also prohibit SpinCo from taking or failing to take any other action that would prevent the Spin-off from qualifying as a transaction that is generally tax-free for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) of the Code. These restrictions may limit the ability of SpinCo to pursue certain equity issuances, strategic transactions, repurchases or other transactions that it may otherwise believe to be in the best interests of its stockholders or that might increase the value of its business. For further discussion of these restrictions, see “Transactions with Related Persons, Promoters and Control Persons — Transactions with Related Persons — Relationship Between IAC and SpinCo After the Spin-Off — Tax Matters Agreement.”

After the Spin-off, actual or potential conflicts of interest may develop between the management and directors of IAC, on the one hand, and the management and directors of SpinCo, on the other hand, or between management and directors of either entity and the management and directors of Expedia Group or Match Group.

After the completion of the Spin-off, the management and directors of IAC and SpinCo may own both IAC capital stock and SpinCo capital stock, and the parties anticipate that certain members of IAC’s senior management team may be directors of SpinCo after the Spin-Off. This overlap could create (or appear to create) potential conflicts of interest when IAC’s and SpinCo’s directors and executive officers face decisions that could have different implications for IAC and SpinCo. For example, potential conflicts of interest could arise in connection with the resolution of any dispute between IAC and SpinCo regarding terms of the agreements governing the Spin-off and the relationship between IAC and SpinCo thereafter, including the separation agreement, the employee matters agreement, the tax matters agreement, the transition services agreement or any commercial agreements between the parties or their affiliates. Potential conflicts of interest could also arise if IAC and SpinCo enter into any commercial arrangements in the future.

Additionally, IAC is asking its stockholders to approve the Corporate Opportunities Proposal. The Corporate Opportunities Proposal contemplates an amendment to the IAC certificate of incorporation to provide that no officer or director of IAC who is also an officer or director of SpinCo, Expedia Group or Match Group will be liable to IAC or its stockholders for breach of any fiduciary duty by reason of the fact that any such individual directs a corporate opportunity to any of such entities instead of IAC, or does not communicate information regarding a corporate opportunity to IAC that the officer or director has directed to any of such entities. SpinCo will have a reciprocal provision in its certificate of incorporation. The corporate opportunity provisions may have the effect of exacerbating the risk of potential conflicts of interest between IAC and SpinCo, or between IAC or SpinCo and Expedia Group or Match Group, because the provisions effectively shield an overlapping director/executive officer from liability for breach of fiduciary duty in the event that such director or officer chooses to direct a corporate opportunity to one of such entities instead of to IAC or SpinCo, as applicable.

The executive officers and directors of IAC have interests in the Spin-off that may be different from, or in addition to, the interests of IAC’s stockholders.

When considering the recommendation of the IAC board of directors that IAC stockholders approve their Spin-off-related proposals, stockholders should be aware that certain directors and executive officers of IAC have certain interests in the Spin-off that may be different from, or in addition to, the interests of such stockholders, including the treatment of outstanding equity awards held by such officers and directors, their roles in IAC and SpinCo following the completion of the Spin-off and indemnification and insurance for current and former directors and executive officers. See the sections entitled “The Spin-off — Interests of IAC Directors and Officers in the Spin-off” for a more detailed description of these interests. As a result of these interests, these directors and executive officers might be more likely to support and to vote in favor of the proposals described in this proxy statement/consent solicitation statement/prospectus than if they did not have these interests. IAC stockholders should consider whether these interests might have influenced these directors and executive officers to recommend in favor of the Spin-off-related proposals.

As a result of the anti-dilution adjustment to be made in favor of third-party stockholders of Vimeo, IAC stockholders will not know with certainty the exact percentage of SpinCo’s outstanding capital stock that will be issued to IAC stockholders as a group, on the one hand, and to third-party stockholders of Vimeo, on the other hand, prior to the closing of the Spin-off.

As described in the section of this proxy statement/consent solicitation statement/prospectus entitled “The Vimeo Merger — Consideration to Vimeo Stockholders,” the magnitude of the anti-dilution adjustment in favor of the non-IAC Vimeo stockholders will not be known with certainty prior to the closing of the Spin- off, and will vary based on the magnitude of the intrinsic value of the outstanding IAC options at closing, and the results of the adjustment of such options in order to allocate them between IAC and SpinCo. Accordingly, IAC stockholders will not know with certainty the exact percentage of SpinCo’s outstanding capital stock immediately following the consummation of the Spin-off and the Vimeo merger that will be issued to the holders of IAC capital stock, as a group, pursuant to the IAC reclassification and the percentage that will be issued in the Vimeo merger to the third-party stockholders of Vimeo. In the event that the magnitude of the anti-dilution adjustment is larger than anticipated, IAC stockholders will collectively own less of an ownership interest in SpinCo than they may have anticipated.

The Spin-off may be abandoned by IAC at any time prior to completion, and is subject to certain closing conditions that, if not satisfied or waived, will result in the Spin-off not being completed. If the Spin-off is not completed, the market price of IAC securities may decline.

The IAC board of directors may abandon the Spin-off at any time prior to completion. In addition, the completion of the Spin-off is subject to the satisfaction (or waiver) of a number of conditions, including the receipt of certain approvals from the stockholders of IAC and the final approval of the IAC board of directors. Some of the conditions to the completion of the Spin-off are outside of the control of IAC and SpinCo. If any condition to the closing of the Spin-off is not satisfied or waived, or if the IAC board of directors otherwise determines to abandon the Spin-off, the Spin-off will not be completed.

The impact of the COVID-19 pandemic and the resulting social and economic disruption may increase the risk that one or more of the closing conditions will not be satisfied and the Spin-off will not occur or that the completion of the Spin-off will be significantly delayed.

If IAC and SpinCo do not complete the Spin-off, the market price of IAC securities may fluctuate to the extent that the current market prices of those shares reflect a market assumption that the Spin-off will be completed. IAC will also be obligated to pay certain legal and accounting fees and related expenses in connection with the Spin-off, whether or not the Spin-off is completed. In addition, each of IAC and Vimeo has expended, and will continue to expend, significant management resources in an effort to complete the Spin-off. If the Spin-off is not completed, IAC and Vimeo will have incurred significant costs, including the diversion of management resources, for which they will have received little or no benefit.

SpinCo or IAC may fail to perform under various transaction agreements that will be executed as part of the Spin- off.

In connection with the Spin-off, SpinCo and IAC will enter into a separation agreement as well as various other agreements, including a transition services agreement, a tax matters agreement and an employee matters agreement. The separation agreement, the tax matters agreement and the employee matters agreement will determine the allocation of assets and liabilities between the companies following the separation for those respective areas and will include indemnification provisions related to certain liabilities and obligations. The transition services agreement will provide for the performance of select services by IAC for the benefit of SpinCo, for a limited period of time after the Spin-off. Each party will rely on the other to satisfy its performance obligations under these agreements. If either party is unable to satisfy its obligations under these agreements, including its indemnification obligations, it could have a material adverse effect on the other party’s results of operations or financial condition.

Challenges in commercial, equity and credit markets may adversely affect the expected benefits of the Spin- off, the expected plans or anticipated timeline to complete the Spin-off and SpinCo’s future access to capital on favorable terms.

Volatility in the world financial markets could adversely impact the market for, or the liquidity of, SpinCo common stock, and/or affect SpinCo’s ability to access the capital markets. In addition, SpinCo’s ability to issue debt or enter into other financing arrangements on acceptable terms could be adversely affected by the volatility in the world financial markets or if there is a material decline in the demand for its products or in the solvency of its customers or suppliers or if there are other significantly unfavorable changes in economic conditions. These conditions may adversely affect the anticipated timeline to complete the Spin-off and the expected benefits of the Spin-off, including by increasing the time and expense involved in the Spin-off or the cost of borrowing after the Spin-off.

SpinCo’s accounting and other management systems and resources may not be adequately prepared to meet the financial reporting and other requirements to which it will be subject as a standalone, publicly traded company following the Spin-off.

Vimeo’s financial results previously were included within the consolidated results of IAC, and it believes its reporting and control systems were appropriate for those of subsidiaries of a public company. However, Vimeo was not directly subject to the reporting and other requirements of the Exchange Act. As a result of the Spin-off, SpinCo will be directly subject to reporting and other obligations under the Exchange Act, including the requirements of Section 404 of the Sarbanes-Oxley Act, which will require annual management assessments of the effectiveness of its internal control over financial reporting and a report by its independent registered public accounting firm addressing these assessments. These reporting and other obligations will place significant demands on SpinCo’s management, administrative and operational resources, including accounting resources. SpinCo may not have sufficient time following the Spin-off to meet these obligations by the applicable deadlines.

Moreover, to comply with these requirements, SpinCo anticipates that it will need to place additional demands on management, migrate its systems, including information technology systems, implement additional financial and management controls, reporting systems and procedures and hire additional personnel. SpinCo expects to incur additional annual expenses related to these steps, and those expenses may be significant and could adversely affect SpinCo’s cash flow and results of operations. If SpinCo is unable to implement its financial and management controls, reporting systems, information technology and procedures in a timely and effective fashion, SpinCo’s ability to comply with its financial reporting requirements and other rules that apply to reporting companies under the Exchange Act could be impaired. Moreover, there can be no assurance that SpinCo’s implementation of additional systems or transition to new systems will be successful, or that such implementation or transition will not present unforeseen costs or demands on SpinCo’s management. Any failure to achieve and maintain effective internal controls could result in adverse regulatory consequences and/or loss of investor confidence, which could limit SpinCo’s ability to access the global capital markets and could have a material adverse effect on SpinCo’s business, financial condition, results of operations, cash flows or the market price of SpinCo securities.

The terms SpinCo will receive in its agreements with IAC could be less beneficial than the terms SpinCo may have otherwise received from unaffiliated third parties.

The agreements SpinCo will enter into with IAC in connection with the Spin-off, including the separation agreement, a tax matters agreement, an employee matters agreement, and an office lease, were prepared in the context of the Spin-off while SpinCo was still a subsidiary of IAC. Accordingly, during the period in which the terms of those agreements were prepared, SpinCo did not have an independent Board of Directors or a management team that was independent of IAC. As a result, the terms of those agreements may not reflect terms that would have resulted from arm’s-length negotiations between unaffiliated third parties. See “Transactions with Related Persons, Promoters and Control Persons — Transactions with Related Persons — Relationship Between IAC and SpinCo After the Spin-Off.”

Failure to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on SpinCo’s business, results of operations or financial condition.

As a public company, SpinCo will be required to prepare its financial statements according to the rules and regulations required by the SEC. In addition, the Exchange Act requires that SpinCo files annual, quarterly and current reports. SpinCo’s failure to prepare and disclose this information in a timely manner or to otherwise comply with applicable law could subject it to penalties under federal securities laws, expose it to lawsuits and restrict its ability to access financing.

In addition, the Sarbanes-Oxley Act requires that, among other things, SpinCo establish and maintain effective internal controls and procedures for financial reporting and disclosure purposes. Internal control over financial reporting is complex and may be revised over time to adapt to changes in SpinCo’s business or changes in applicable accounting rules. SpinCo cannot assure its stockholders that its internal control over financial reporting will be effective in the future or that a material weakness will not be discovered with respectto a prior period for which SpinCo had previously believed that its internal controls were effective. If SpinCo is not able to maintain or document effective internal control over financial reporting, its independent registered public accounting firm will not be able to certify as to the effectiveness of its internal control over financial reporting.

Matters affecting SpinCo’s internal controls may cause it to be unable to report its financial information on a timely basis, or may cause SpinCo to restate previously issued financial information, and thereby subject it to adverse regulatory consequences, including sanctions or investigations by the SEC, or violations of applicable stock exchange listing rules. There could also be a negative reaction in the financial markets due to a loss of investor confidence in the company and the reliability of SpinCo’s financial statements. Confidence in the reliability of SpinCo’s financial statements is also likely to suffer if it reports, or its independent registered public accounting firm reports, a material weakness in SpinCo’s internal control over financial reporting. This could have a material adverse effect on SpinCo’s business, results of operations or financial condition and could lead to a decline in the share price of SpinCo common stock or impairing SpinCo’s ability to raise additional capital.

Risks Relating to IAC Securities and SpinCo Securities Following the Spin-off

The aggregate value of the IAC and SpinCo securities that current holders of IAC capital stock receive in the Spin-off might be less than the value of the IAC securities they held before the Spin-off.

If IAC completes the Spin-off, holders of IAC capital stock as of immediately prior to the Spin-off will receive a combination of shares of IAC capital stock and SpinCo capital stock. The prices at which shares of IAC securities and/or SpinCo securities may trade at post-Spin-off are unpredictable. Therefore, the combined market value of one share of IAC common stock and [·] shares of SpinCo common stock post- Spin-off may be less than, equal to or greater than the market value of one share of IAC common stock prior to the Spin-off.

Additionally, the value of IAC securities and/or SpinCo securities may be negatively impacted by a number of factors, after the completion of the Spin-off. Some of these matters are described in these risk factors and others may or may not have been identified by IAC or SpinCo prior to the completion of the Spin- off, and many of them are not within IAC’s or SpinCo’s control. Should any adverse circumstances, facts, changes or effects come to pass, the combined value of the IAC and SpinCo securities could be less than the value of IAC securities before the Spin-off.

There is currently no public market for shares of SpinCo common stock.

SpinCo cannot guarantee that an active and liquid market for its shares of common stock will develop when trading begins. Even if it does, the price of per share of SpinCo common stock may be subject to significant volatility. Your investment in SpinCo will have a substantially different risk profile from your investment in IAC because: (1) Vimeo only participates (and SpinCo will only participate) in the highly competitive market for SaaS video services, whereas IAC operates a portfolio of businesses with varying business models and markets; and (2) Vimeo, unlike IAC, does not have a history of profitability. As a result, an investment in shares of SpinCo common stock may not be a suitable

investment for some IAC shareholders, who may in turn sell such shares after trading begins. There can be no assurance that any such sales will be offset by purchases by investors seeking a higher risk asset. As a result, the price per share of SpinCo common stock could fall once trading begins.

The market price and trading volume of IAC and/or SpinCo securities may be volatile and may face negative pressure.

IAC cannot accurately predict how investors in IAC and/or SpinCo securities will behave after the Spin- off. The market price for IAC and/or SpinCo securities following the Spin-off may be more volatile than the market price of IAC securities before the Spin-off. IAC currently owns SpinCo and the businesses that SpinCo will operate following the Spin-off. Therefore, there is currently no trading market for SpinCo’s securities and the SpinCo securities issued in the Spin-off will be trading publicly for the first time post-Spin- off. In addition, there can be no assurance that a trading market for SpinCo’s securities, if any, will develop. Until, and possibly even after, orderly trading markets develop for these securities, there may be significant fluctuations in price due to a variety of factors.

The market price of IAC and SpinCo securities could fluctuate significantly for many reasons, including the risks identified in this proxy statement/consent solicitation statement/prospectus or reasons unrelated to each company’s performance. Among the factors that could affect each company’s stock price are:

These factors, among others, may result in short- or long-term negative pressure on the value of IAC and/or SpinCo securities.

The dual-class common stock structure of each of IAC and SpinCo may negatively impact the market price of their respective common stock.

We cannot predict whether the dual-class common stock structure of each of IAC and SpinCo, combined with the concentrated control of Mr. Diller and members of his family as the holders of all of the outstanding Class B common stock of each company following the Spin-off, will result in a lower or more volatile market price of IAC common stock or SpinCo common stock, or other adverse consequences.

For example, certain stock index providers, such as S&P Dow Jones, exclude companies with multiple classes of shares of common stock from being added to certain stock indices, including the S&P 500. In addition, several stockholder advisory firms and large institutional investors oppose the use of multiple class structures. As a result, the dual class structure of the common stock of each of IAC and Vimeo may prevent the inclusion of either company’s common stock in such indices, may cause stockholder advisory firms to publish negative commentary about its corporate governance practices of either company or otherwise seek to cause either company to change its capital structure, and may result in large institutional investors not purchasing shares of either company’s common stock. Any exclusion from stock indices could result in a less active trading market for IAC common stock and/or SpinCo common stock. Any actions or publications by stockholder advisory firms or institutional investors critical of IAC’s or SpinCo’s corporate governance practices or capital structure could also adversely affect the value of IAC common stock or SpinCo common stock.

The difference in the voting rights between the common stock and Class B common stock of each of IAC and SpinCo could also harm the value of such company’s common stock to the extent that any investor or potential future purchaser of IAC common stock or SpinCo common stock ascribes value to the right of holders of such company’s Class B common stock to ten votes per share of Class B common stock, or could potentially result in the Class B common stock of either IAC or SpinCo receiving higher consideration in a sale of such company than that paid to holders of IAC common stock or SpinCo common stock. The existence of two classes of common stock could also result in less liquidity for either Company’s Class A common stock than if there were only one class of common stock.

Substantial sales of IAC common stock following the Spin-off, or the perception that such sales might occur, could depress the market price of IAC common stock, which is already expected to be lower than the pre-Spin- off market price of IAC common stock due to IAC no longer having any ownership interest in SpinCo or its businesses.

The post-Spin-off market price of IAC common stock is expected to be lower than the pre-Spin-off market price of IAC common stock, as IAC will no longer have an ownership interest in Vimeo or its businesses. In addition, the smaller size and different investment characteristics of IAC may not appeal to the current investor base of IAC and/or could result in less equity analyst coverage, which could result in sales of substantial amounts of IAC common stock in the public market following the Spin-off, or the perception that such sales might occur. There is no assurance that there will be sufficient buying interest to offset any such sales, and, accordingly, the price of IAC common stock may be depressed by those sales and have periods of volatility.

Substantial sales of SpinCo common stock following the Spin-off, or the perception that such sales might occur, could depress the market price of SpinCo common stock.

Holders of IAC capital stock may not wish to continue to hold the shares of SpinCo capital stock that they will receive as a result of the Spin-Off, which may lead to the disposition of a substantial number of shares of SpinCo common stock following the Spin-off. There is no assurance that there will be sufficient buying interest to offset any such sales, and, accordingly, the price of SpinCo common stock may be depressed by those sales, or by the perception that such sales may occur, and have periods of volatility.

After the Spin-off, financial institutions may remove IAC securities from investment indices and SpinCo securities may not qualify for those investment indices. In addition, IAC securities and/or SpinCo securities may fail to meet the investment guidelines of institutional investors. In either case, these factors may negatively impact the price of IAC securities and/or SpinCo securities and may impair IAC’s and/or SpinCo’s ability to raise capital through the sale of securities.

Some of the holders of IAC securities are index funds tied to Nasdaq or other stock or investment indices, or are institutional investors bound by various investment guidelines. Companies are generally selected for investment indices, and in some cases selected by institutional investors, based on factors such as market capitalization, industry, trading liquidity and financial condition. The Spin-off will reduce IAC’s market capitalization. Similarly, as an independent company, SpinCo will initially have a lower market capitalization than IAC has today. As a result, one or more investment indices may remove IAC securities from their indices and SpinCo securities may not qualify for those investment indices. In addition, IAC and/or SpinCo securities that are received in the Spin-off may not meet the investment guidelines of some institutional investors. Consequently, these index funds and institutional investors may have to sell some or all of the securities they receive in the Spin-off, and the prices of IAC and/or SpinCo securities may fall as a result. Any such decline could impair the ability of IAC or SpinCo to raise capital through future sales of securities.

Neither IAC nor SpinCo is expected to declare any regular cash dividends in the foreseeable future.

Neither IAC nor SpinCo is expected to pay cash dividends on its capital stock in the near term. Instead, it is anticipated that each of IAC’s and SpinCo’s future earnings will be retained to support its operations and to finance the

growth and development of its business. Any future determination relating to IAC’s or SpinCo’s dividend policy will be made by IAC’s or SpinCo’s, as applicable, board of directors and will depend on a number of factors, including:

In the absence of dividends, investors may need to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

Provisions in the IAC and SpinCo certificates of incorporation and bylaws or Delaware law may discourage, delay or prevent a change of control of IAC or SpinCo, respectively, or changes in their management and, therefore, depress the trading price of their common stock.

The DGCL and IAC’s certificate of incorporation and bylaws contain, and SpinCo’s certificate of incorporation and bylaws will contain, provisions that could discourage, delay or prevent a change in control of IAC or SpinCo, respectively, or changes in their management that their respective stockholders may deem advantageous, including each respective company’s dual-class structure and the existence of the high-vote common stock, and provisions which:

Any provision of IAC’s or SpinCo’s certificate of incorporation, its bylaws or Delaware law that has the effect of delaying, deterring or preventing a change in control could limit the opportunity for its stockholders to receive a premium for their shares of capital stock, and could also affect the price that some investors are willing to pay for such capital stock.

If securities or industry analysts do not publish research or publish unfavorable research about SpinCo or IAC, the applicable company’s stock price and trading volume could decline.

The trading market for SpinCo common stock and IAC common stock will be influenced by the research and reports that industry or securities analysts publish about SpinCo or IAC, respectively, and their respective businesses. If one or more of these analysts ceases coverage, or fails to publish reports about the applicable company regularly, IAC or SpinCo, as applicable, could lose visibility in the financial markets, which in turn could cause its stock price or trading volume to decline. Moreover, if SpinCo or IAC’s operating results do not meet the expectations of the investor

community, one or more of the analysts who cover such company may change their recommendations regarding such company, and the applicable stock price could decline.

Risks Relating to IAC’s Business Following the Spin-off

Marketing efforts designed to drive visitors to IAC’s various brands and businesses may not be successful or cost-effective.

Traffic building and conversion initiatives involve considerable expenditures for online and offline advertising and marketing. IAC has made, and expects to continue to make, significant expenditures for search engine marketing (primarily in the form of the purchase of keywords, which it purchases primarily through Google and, to a lesser extent, Microsoft and Yahoo!), online display advertising and traditional offline advertising (including television and radio campaigns) in connection with these initiatives, which may not be successful or cost-effective. Also, to continue to reach consumers and users, IAC will need to identify and devote more of its overall marketing expenditures to newer digital advertising channels (such as online video and other digital platforms), as well as target consumers and users via these channels. Since these channels are undeveloped and unproven relative to traditional channels (such as television), it could be difficult to assess returns on related marketing investments. Historically, IAC has had to increase advertising and marketing expenditures over time in order to attract and convert consumers, retain users and sustain its growth.

IAC’s ability to market its brands and businesses on any given property or channel is subject to the policies of the relevant third-party seller, publisher (including search engines and social media platforms with extraordinarily high levels of traffic and numbers of users) or marketing affiliate. As a result, IAC cannot assure you that these parties will not limit or prohibit IAC from purchasing certain types of advertising (including the purchase by IAC of advertising with preferential placement or for certain of its products and services) and/or using one or more current or prospective marketing channels in the future. If a significant marketing channel took such an action generally, for a significant period of time and/or on a recurring basis, IAC’s business, financial condition and results of operations could be adversely affected. In addition, if IAC fails to comply with the policies of third-party sellers, publishers and/or marketing affiliates, its advertisements could be removed without notice and/or its accounts could be suspended or terminated, any of which could adversely affect IAC’s business, financial condition and results of operations.

IAC relies heavily on free search engine marketing to drive traffic to its properties. The display, including rankings, of search results can be affected by a number of factors, many of which are not in IAC’s direct control, and may change frequently. Search engines have made changes in the past to their ranking algorithms, methodologies and design layouts that have reduced the prominence of links to websites offering IAC’s products and services, and negatively impacted traffic to such websites, and IAC expects that search engines will continue to make such changes from time to time in the future. However, IAC may not know how (or otherwise be in a position) to influence actions of this nature taken by search engines. With respect to search results in particular, even when search engines announce the details of their methodologies, their parameters may change from time to time, be poorly defined or be inconsistently interpreted.

The failure of IAC to respond successfully to rapid and frequent changes in the operating and pricing dynamics of search engines, as well as changing policies and guidelines applicable to keyword advertising (which may be unilaterally updated by search engines without advance notice), could adversely affect its paid and free search engine marketing efforts. Specifically, such changes could adversely affect paid listings (both their placement and pricing), as well as the ranking of links to websites offering IAC’s products and services within search results, any or all of which could increase IAC’s marketing costs (particularly if free traffic is replaced with paid traffic) and adversely affect the effectiveness of its marketing efforts overall.

Lastly, certain IAC businesses also enter into various arrangements with third parties (including advertising agencies) to drive traffic to their various brands and businesses and generate leads, which arrangements are generally more cost-effective than traditional marketing efforts. If these businesses are unable to renew existing (and enter into new) arrangements of this nature, sales and marketing costs as a percentage of revenue would increase over the long-term, which could adversely affect IAC’s business, financial condition and results of operations. In addition, the quality and convertibility of traffic and leads generated through third-party arrangements are dependent on many factors, most of which are outside IAC’s control. If the quality and/or convertibility of traffic and leads do not meet the expectations

of the users of IAC’s various products and services, its paid listings providers and/or advertisers, its business, financial condition and results of operations could be adversely affected.

IAC relies on search engines to drive traffic to its various properties. Certain search engine operators offer products and services that compete directly with IAC’s products and services. If links to websites offering IAC products and services are not displayed prominently in search results, traffic to IAC’s properties could decline and its business could be adversely affected.

As discussed above, the amount of traffic IAC attracts through search engines is due in large part to how and where information from (and links to websites offering IAC products and services) are displayed on search engine results pages. Certain search engine operators offer products and services that compete directly with IAC’s products and service and may change their displays or rankings in order to promote their products or services, or the products or services of one or more of IAC’s competitors. Any such action could negatively impact the search rankings of links to websites offering IAC products and services, or the prominence with which such links appear in search results. IAC’s success depends on the ability of links to websites offering IAC’s products and services to maintain a prominent position in search results, and in the event operators of search engines promote their own competing products in the future in a manner that has the effect of reducing the prominence or ranking of links to websites offering IAC’s products and services, IAC’s business, financial condition and results of operations could be adversely affected.

Certain of IAC’s businesses depend upon arrangements with Google.

A meaningful portion of IAC’s consolidated revenue (and a substantial portion of IAC’s net cash from operations that it can freely access) is attributable to a services agreement with Google. Pursuant to this agreement, IAC displays and syndicates paid listings provided by Google in response to search queries generated through the businesses within its Search segment. In exchange for making its search traffic available to Google, IAC receives a share of the revenue generated by the paid listings supplied to IAC, as well as certain other search related services. IAC’s agreement with Google expires on March 31, 2023; provided, however, that only in September of each year, IAC or Google may, after discussion with the other party, terminate the services agreement, effective on September 30 of the year following the year such notice is given.

The amount of revenue IAC receives from Google depends on a number of factors outside of IAC’s control, including the amount Google charges for advertisements, the efficiency of Google’s system in attracting advertisers and serving up paid listings in response to search queries and parameters established by Google regarding the number and placement of paid listings displayed in response to search queries. In addition, Google makes judgments about the relative attractiveness (to advertisers) of clicks on paid listings from searches performed on IAC’s properties and these judgments factor into the amount of revenue IAC receives. Google also makes judgments about the relative attractiveness (to users) of paid listings from searches performed on IAC’s properties and these judgments factor into the number of advertisements IAC can purchase. Changes to the amount Google charges advertisers, the efficiency of Google’s paid listings network, Google’s judgment about the relative attractiveness to advertisers of clicks on paid listings from IAC’s properties or to the parameters applicable to the display of paid listings generally could result in a decrease in the amount of revenue IAC receives from Google and could adversely affect IAC’s business, financial condition and results of operations. Such changes could come about for a number of reasons, including general market conditions, competition or policy and operating decisions made by Google.

IAC’s services agreement with Google also requires that IAC comply with certain guidelines for the use of Google brands and services, including the Chrome browser and Chrome Web Store. These guidelines govern which of IAC’s products and applications may access Google services or be distributed through its Chrome Web Store, and the manner in which Google’s paid listings are displayed within search results across various third-party platforms and products (including IAC’s properties). IAC’s services agreement also requires that it establish guidelines to govern certain activities of third parties to whom it syndicates paid listings, including the manner in which these parties drive search traffic to their websites and display paid listings. Google may generally unilaterally update its policies and guidelines without advance notice, whether under the services agreement or otherwise, which could in turn require modifications to, or prohibit and/or render obsolete certain of its products, services and/or business practices, which could be costly to address or otherwise adversely affect IAC’s business, financial condition and results of operations. Noncompliance with

Google’s guidelines by IAC or the third parties to whom it is permitted to syndicate paid listings or through which IAC secures distribution arrangements for the businesses within its Search segment could result in the suspension of some or all Google services to IAC (or the websites of IAC’s third party partners) and/or the termination of the services agreement by Google. Google has, in the past, made policy changes generally and under the services agreement, which had a negative impact on the historical and expected future results of operations of IAC’s Desktop business, and may do so in the future. In addition, in the last quarter of 2020, Google suspended services with respect to some of IAC’s Desktop products and may take continued or further action with respect to IAC’s products and businesses in the future.

The termination of the services agreement by Google, the curtailment of IAC’s rights under the agreement, including the failure to allow IAC products to access Google services (whether pursuant to the terms thereof or otherwise), and/or the failure of Google to perform its obligations under the agreement and/or policy changes implemented by Google under the services agreement or otherwise would have an adverse effect on IAC’s business, financial condition and results of operations. If any of these events were to occur, IAC may not be able to find another suitable alternate provider of paid listings (or if an alternate provider were found, the economic and other terms of the agreement and the quality of paid listings may be inferior relative to IAC’s arrangements with (and the paid listings supplied by) Google) or otherwise replace the lost revenues.

IAC’s success depends, in substantial part, on its continued ability to market, distribute and monetize its products and services through search engines, digital app stores and social media platforms.

The marketing, distribution and monetization of IAC’s products and services depends on its ability to cultivate and maintain cost-effective and otherwise satisfactory relationships with search engines, digital app stores and social media platforms, in particular, those operated by Apple, Google and Facebook. These platforms could decide not to market and distribute some or all of IAC’s products and services, change their terms and conditions of use at any time (and without notice), favor their own products and services over IAC’s products and services and/or significantly increase their fees. While IAC expects to maintain cost-effective and otherwise satisfactory relationships with these platforms, no assurances can be provided that IAC will be able to do so and its inability to do so in the case of one or more of these platforms could have a material adverse effect on IAC’s business, financial condition and results of operations.

In particular, as consumers increasingly access IAC’s products and services through applications (both mobile and desktop), IAC increasingly depends upon the Apple App Store, Google Play Store and Google’s Chrome Web Store to distribute its mobile and desktop browser applications. Both Apple and Google have broad discretion to change their respective terms and conditions applicable to the distribution of IAC’s applications, including those relating to the amount of (and requirement to pay) certain fees associated with purchases facilitated by Apple and Google through IAC’s applications, their ability to interpret their respective terms and conditions in ways that may limit, eliminate or otherwise interfere with IAC’s ability to distribute its applications through their stores, the features IAC may provide in its products and services, IAC’s ability to access information about its subscribers and users that they collect and the manner in which IAC markets in-app products. Apple or Google could also make changes to their operating systems or payment services that could negatively affect IAC. No assurances can be provided that Apple and/or Google will not interpret their respective terms and conditions in the manner described above and to the extent either or both of them do so, IAC’s business, financial condition and results of operations could be adversely affected.

While some of IAC’s mobile applications are generally free to download from the Apple App and Google Play Stores, many of them are subscription-based. While IAC determines the prices at which these subscriptions are sold, currently, all related purchases must be processed through the in-app payment systems provided by these stores, for which IAC pays these stores a meaningful share (generally 30%) of the related revenue it receives. Given the increasing distribution of its mobile applications through digital app stores and strict in-app payment system requirements, IAC may need to offset increased digital app store fees by decreasing traditional marketing expenditures as a percentage of revenue, increasing user volume or monetization per user or engaging in other efforts to increase revenue or decrease costs generally, or its business, financial condition and results of operations could be adversely affected.

IAC’s success depends, in part, upon the continued migration of certain markets and industries online and the continued growth and acceptance of online products and services as effective alternatives to traditional offline products and services.

Through its various businesses, IAC provides a variety of online products and services that continue to compete with their traditional offline counterparts. IAC believes that the continued growth and acceptance of online products and services generally will depend, to a large extent, on the continued growth in commercial use of the Internet (particularly abroad) and the continued migration of traditional offline markets and industries online.

For example, the success of the businesses within IAC’s ANGI Homeservices segment and Care.com business depends, in substantial part, on the continued migration of the home services and care-related services markets online. If for any reason these markets do not migrate online as quickly as (or at lower levels than) IAC expects and consumers and service professionals (and subscribers and caregivers) continue, in large part, to rely on traditional offline efforts to connect with one another, IAC’s business, financial condition and results of operations could be adversely affected.

Lastly, the success of IAC’s advertising-supported businesses also depends, in part, on their ability to compete for a share of available advertising expenditures as more traditional offline and emerging media companies continue to enter the online advertising market, as well as on the continued growth and acceptance of online advertising generally. Any lack of growth in the market for online advertising could adversely affect IAC’s business, financial condition and results of operations.

The success of IAC depends, in part, on its continued ability to develop and monetize versions of its products and services for mobile and other digital devices.

As consumers increasingly access IAC’s products and services through mobile and other digital devices (including through digital voice assistants), IAC will need to continue to devote significant time and resources to ensure that its products and services are accessible across these platforms (and multiple platforms generally). If IAC does not keep pace with evolving online, market and industry trends (including the introduction of new and enhanced digital devices and changes in the preferences and needs of consumers generally), offer new and/or enhanced products and services in response to such trends that resonate with consumers, monetize products and services for mobile and other digital devices as effectively as its traditional products and services and/or maintain related systems, technology and infrastructure in an efficient and cost-effective manner, IAC’s business, financial condition and results of operations could be adversely affected.

In addition, the success of IAC’s mobile and other digital products and services depends on their interoperability with various third-party operating systems, technology, infrastructure and standards, over which IAC has no control. Any changes to any of these things that compromise the quality or functionality of IAC’s mobile and digital products and services could adversely affect their usage levels and/or IAC’s ability to attract consumers and advertisers, which could adversely affect IAC’s business, financial condition and results of operations.

The success of IAC depends, in part, of the ability of ANGI Homeservices and Care.com to establish and maintain relationships with quality and trustworthy service professionals and caregivers.

IAC must continue to attract, retain and grow the number of skilled and reliable service professionals who can provide services across ANGI Homeservices platforms and caregivers who can provide care-related services through the Care.com platform. If IAC does not offer innovative products and services that resonate with consumers and service professionals (and subscribers and caregivers) generally, as well provide service professionals and caregivers with an attractive return on their marketing and advertising investments, the number of service professionals and caregivers affiliated with ANGI Homeservices and Care.com platforms, respectively, would decrease. Any such decrease would result in smaller and less diverse networks and directories of service professionals and caregivers, and in turn, decreases in service requests, pre-priced bookings and directory searches, as well as subscriber requests for caregivers, which could adversely impact IAC’s business, financial condition and results of operations.

In addition to skill and reliability, consumers and families want to work with service professionals and caregivers whom they can trust to work in their homes and with their family members and with whom they can feel safe. While there are screening processes and certain other safety-related measures in place at these businesses (which generally include certain, limited background checks) to try and prevent unsuitable service professionals and caregivers from joining and remaining on IAC’s platforms, these processes have limitations and, even with these safety measures, no assurances can be provided regarding the future behavior of any service provider or caregiver on IAC’s platforms. Inappropriate and/or unlawful behavior on the part of service professionals and caregivers generally (particularly any such behavior that compromises their trustworthiness and/or of the safety of consumers and families) could result in decreases in service requests and subscriber requests for caregivers and related care services, bad publicity and related damage to IAC’s reputation, brands and brand-building efforts and/or actions by governmental and regulatory authorities, criminal proceedings and/or litigation. The occurrence or any of these events could, in turn, adversely affect IAC’s business, financial condition and results of operations.

IAC’s success depends, in part, on the ability of ANGI Homeservices to expand pre-priced booking services.

Through certain businesses within IAC’s ANGI Homeservices segment, IAC provides pre-priced booking services, pursuant to which IAC contracts with service professionals to perform specific tasks for specific consumers at an agreed upon price. In contrast to Marketplace service requests, pursuant to which IAC matches service professionals to consumer opportunities, through IAC’s pre-priced booking services IAC contracts directly with a service professional to perform a contracted task at a contracted price. Increases in pre-priced bookings (which IAC expects to be the case over time) could reduce the level of service provider responses to service requests through the Marketplace and IAC’s directories.

In addition, while pre-priced booking services offer potentially higher profit opportunities, they also involve greater financial risk because IAC bears the impact of cost overruns, which could result in increased costs and expenses. For example, IAC could miscalculate the costs, materials and/or or time needed to complete consumer requests or consumers could provide IAC with inaccurate information, which could result in IAC charging consumers too little for contracted tasks, which in turn would result in IAC having to absorb the actual, higher cost for contracted tasks or risk not being able to find service professionals to perform contracted tasks at contracted rates. IAC’s business, financial condition and results of operations could be adversely affected if IAC’s actual costs exceed the assumptions used in offering contracted tasks through IAC’s pre-priced booking services.

IAC’s ability to engage directly with its users, subscribers, consumers, service professionals and caregivers directly on a timely basis is critical to its success.

As consumers increasingly communicate via mobile and other digital devices and messaging and social media apps, usage of email (particularly among younger consumers) has declined and IAC expects this trend to continue. In addition, deliverability and other restrictions could limit or prevent the ability of IAC to send emails to users, subscribers, consumers, service professionals and caregivers. A continued and significant erosion in IAC’s ability to engage with users, subscribers, consumers, service professionals and caregivers via email could adversely impact the user experience, engagement levels and conversion rates, which could adversely affect IAC’s business, financial condition and results of operations. IAC cannot assure you that any alternative means of communication (for example, push notifications and text messaging) will be as effective as email has been historically.

The success of IAC depends, in part, on its ability to access, collect and use personal data about its users and subscribers.

IAC depends on search engines, digital app stores and social media platforms, in particular, those operated by Google, Apple and Facebook, to market, distribute and monetize its products and services. IAC’s users and subscribers engage with these platforms directly, and in the case of digital app stores, may be subject to requirements regarding the use of their payment systems for various transactions. As a result, these platforms may receive personal data about IAC’s users and subscribers that IAC would otherwise receive if it transacted with its users and subscribers directly. Certain of these platforms have restricted IAC’s access to personal data about its users and subscribers obtained through their platforms. If these platforms limit or increasingly limit, eliminate or otherwise interfere with IAC’s ability to access,

collect and use personal data about its users and subscribers that they have collected, the ability of IAC to identify and communicate with a meaningful portion of its user and subscriber bases may be adversely impacted. If so, IAC’s customer relationship management efforts, its ability to identify, target and reach new segments of its user and subscriber bases and the population generally, the efficiency of its paid marketing efforts, the rates IAC is able to charge advertisers seeking to reach users and subscribers on its various properties and IAC’s ability to develop and implement safety features, policies and procedures for certain of its products and services could be adversely affected. IAC cannot assure you that the search engines, digital app stores and social media platforms upon which it relies will not limit or increasingly limit, eliminate or otherwise interfere with its ability to access, collect and use personal data about its users and subscribers that they have collected. To the extent that any or all of them do so, IAC’s business, financial condition and results of operations could be adversely affected.

Mr. Diller, certain members of his family and Mr. Levin are able to exercise significant influence over the composition of IAC’s Board of Directors, matters subject to stockholder approval and IAC’s operations.

As of [·], Mr. Diller, his spouse, Diane von Furstenberg, and his stepson, Alexander von Furstenberg, collectively held shares of IAC Class B common stock and IAC common stock that represented approximately [·]% of the total outstanding voting power of IAC (based on the number of shares of IAC common stock outstanding and entitled to vote as of [·]) and they will collectively hold shares of IAC Class B common stock and IAC common stock representing the same percentage of the total outstanding voting power of IAC following the Spin-off as they hold immediately before the Spin-off. These shares are also subject to a voting agreement with Mr. Levin, IAC’s Chief Executive Officer, and will continue to be following the Spin-off.

As a result of IAC securities that will be beneficially owned by these individuals following the completion of the Spin-off, such individuals will be, collectively, in a position to influence (subject to IAC’s organizational documents and Delaware law), the composition of IAC’s Board of Directors and the outcome of corporate actions requiring shareholder approval, such as mergers, business combinations and dispositions of assets, among other corporate transactions. As a result of the Voting Agreement, Mr. Levin is currently in a position, subject to IAC’s organizational documents and Delaware law, to influence his election to IAC’s board of directors and influence the outcome of Contingent Matters (as defined in the Voting Agreement). This concentration of investment and voting power could discourage others from initiating a potential merger, takeover or other change of control transaction that may otherwise be beneficial to IAC and its shareholders, which could adversely affect the market price of IAC securities.

In addition, the holders of the Class B common stock could sell all or a portion of those shares to a third party, which could result in the purchaser obtaining significant influence over IAC, the composition of IAC’s Board of Directors, matters subject to stockholder approval and IAC’s operations, without consideration being paid to holders of shares of IAC common stock, and without holders of shares of IAC common stock having a right to consent to the identity of such purchaser. Pursuant to the Voting Agreement, if any of the holders of the Class B common stock were to determine to sell shares of Class B common stock to a person other than Mr. Diller, his family members or certain entities controlled by such persons, they have agreed that they will discuss with Mr. Levin selling such shares to him before selling to any other party.

IAC may not freely access the cash of ANGI Homeservices and its subsidiaries.

Potential sources of cash for IAC include its available cash balances, net cash from the operating activities of certain of its subsidiaries and proceeds from asset sales, including marketable securities. While the ability of IAC’s operating subsidiaries to pay dividends or make other payments or advances to IAC depends on their individual operating results and applicable statutory, regulatory or contractual restrictions generally, in the case of ANGI Homeservices, the terms of its indebtedness limit its ability to pay dividends or make distributions, loans or advances to stockholders (including IAC) in certain circumstances. In addition, because ANGI Homeservices is a separate and distinct legal entity with public shareholders, it has no obligation to provide IAC with funds.

You may experience dilution with respect to your investment in IAC, and IAC may experience dilution with respect to its investment in ANGI Homeservices, as a result of compensatory equity awards.

IAC has issued various compensatory equity awards, including stock options, shares of restricted stock, stock appreciation rights and restricted stock unit awards denominated in shares of its common stock, as well as in equity of certain of its consolidated subsidiaries, including ANGI Homeservices.

The issuance of shares of IAC common stock in settlement of these equity awards could dilute your ownership interest in IAC. ANGI Homeservices compensatory equity awards that are settled in shares of ANGI Homeservices could dilute IAC’s ownership interest in ANGI Homeservices. The dilution of IAC’s ownership stake in ANGI Homeservices could impact its ability, among other things, to maintain ANGI Homeservices as part of its consolidated tax group for U.S. federal income tax purposes, to effect a tax-free distribution of its ANGI Homeservices stake to its stockholders or to maintain control of ANGI Homeservices. As IAC generally has the right to maintain its levels of ownership in ANGI Homeservices to the extent ANGI Homeservices issues additional shares of its capital stock in the future pursuant to an investor rights agreement, IAC does not intend to allow any of the foregoing to occur.

With respect to awards denominated in shares of IAC’s non-publicly traded subsidiaries, IAC estimates the dilutive impact of those awards based on its estimated fair value of those subsidiaries. Those estimates may change from time to time, and the fair value determined in connection with vesting and liquidity events could lead to more or less dilution than reflected in IAC’s diluted earnings per share calculation.

General Risk Factors

IAC’s businesses operate in especially competitive and evolving industries.

The industries in which IAC’s brands and businesses operate are competitive, with a consistent and growing stream of new products and entrants. Some of IAC’s competitors may enjoy better competitive positions in certain geographical areas, user demographics and/or other key areas that IAC currently serves or may serve in the future. Generally (and particularly in the case of the businesses within IAC’s ANGI Homeservices segment), IAC competes with search engine providers and online marketplaces that can market their products and services online in a more prominent and cost-effective manner than IAC can. IAC also generally competes with social media platforms with access to large existing pools of potential users and their personal information, which means these platforms can drive visitors to their products and services, as well as better tailor products and service to individual users, at little to no cost relative to IAC’s efforts. Any of these advantages could enable IAC’s competitors to offer products and services that are more appealing to consumers than its products and services, respond more quickly and/or cost effectively than IAC does to evolving market opportunities and trends and/or display their own integrated or related products and services in a more prominent manner than IAC’s products and services in search results, which could adversely affect IAC’s business, financial condition and results of operations.

In addition, costs to switch among products and services are low or non-existent and consumers generally have a propensity to try new products and services (and use multiple products and services simultaneously). As a result, IAC expects the continued emergence of new products and services, entrants and business models in the various industries in which its brands and businesses operate. IAC’s inability to continue to innovate and compete effectively against new products, services and competitors could result in decreases in the size and levels of engagement of its various user and subscriber bases, which could adversely affect IAC’s business, financial condition and results of operations.

IAC’s businesses are sensitive to general economic events or trends, particularly those that adversely impact advertising spending levels and consumer confidence and spending behavior.

A significant portion of IAC’s consolidated revenue (and a substantial portion of IAC’s net cash from operations that it can freely access), is attributable to online advertising, primarily revenue from the businesses within IAC’s Dotdash and Search segments. Accordingly, events and trends that result in decreased advertising expenditures and/or levels of consumer confidence and discretionary spending could adversely affect IAC’s business, financial condition and results of operations.

Similarly, the businesses within IAC’s ANGI Homeservices segment are particularly sensitive to events and trends that could result in consumers delaying or foregoing home services projects (including difficulties obtaining financing for such projects) and service professionals being less likely to pay for consumer matches, pre-priced bookings, Marketplace subscriptions and/or time-based advertising, which could result in decreases in Marketplace service requests, pre-priced bookings and directory searches. Any such decreases could result in turnover at the Marketplace and/or any ANGI Homeservices directories, adversely impact the number and quality of service professionals at the Marketplace and in any ANGI Homeservices directories and/or adversely impact the reach of (and breath of services offered through) the Marketplace and ANGI Homeservices directories, any or all of which could adversely affect IAC’s business, financial condition and results of operations. Also, negative changes in capital markets could adversely impact the ability of the third party with which ANGI Homeservices has contracted to offer a consumer financing option through the HomeAdvisor Pro-Pay App to fulfill its obligations, which could adversely impact the launch and ongoing rollout of this option, and in turn, IAC’s business, financial condition and results of operations.

The success of IAC depends, in part, on its ability to build, maintain and/or enhance its various brands.

Through its various businesses, IAC owns and operates a number of widely known consumer brands with strong brand appeal and recognition within their respective markets and industries, as well as a number of emerging brands that it is in the process of building. IAC believes that its success depends, in large part, on its continued ability to maintain and enhance its established brands, as well as build awareness of (and loyalty to) its emerging brands. Events that could adversely impact IAC’s brands and brand-building efforts include (among others): product and service quality concerns, consumer complaints or lawsuits, lack of awareness of the policies of IAC’s various businesses and/or how they are applied in practice, IAC’s failure to respond to user, service professional and caregiver feedback, ineffective advertising, inappropriate and/or unlawful actions taken by users, service professionals and caregivers, actions taken by governmental or regulatory authorities, data protection and security breaches and related bad publicity. The occurrence or any of these events could, in turn, adversely affect IAC’s business, financial condition and results of operations.

The global outbreak of COVID-19 and other similar outbreaks could adversely affect IAC’s business, financial condition and results of operations.

IAC’s business could be materially and adversely affected by the outbreak of a widespread health epidemic or pandemic, including the continuing outbreak of the coronavirus (COVID-19), which has been declared a “pandemic” by the World Health Organization. The continuing outbreak of COVID-19 has caused a widespread global health crisis, and governments in affected regions have implemented measures designed to curb its spread, such as social distancing, government-imposed quarantines and lockdowns, travel bans and other public health safety measures. These measures have resulted in significant social disruption and have had (and are likely to continue to have) an adverse effect on economic conditions generally, advertising expenditures and consumer confidence and spending, all of which could have an adverse effect on IAC’s businesses, financial condition and results of operations.

Since the initial outbreak, the impact of COVID-19 on IAC’s businesses has varied from business to business and from month to month. To date, demand for certain of IAC’s products and services and advertising rates have generally decreased and, despite increased service requests at IAC’s ANGI Homeservices business, the limited ability of service professionals to fulfill these requests as a result of labor and material constraints has negatively impacted the ability of ANGI Homeservices to monetize these requests. ANGI Homeservices continued to experience strong demand for home services in the second half of 2020. Also, to date IAC’s Vimeo business has seen strong revenue growth as the demand for communication via video has increased due to the pandemic. Lastly, certain of IAC’s advertising-supported businesses experienced a decline in revenue due, in part, to decreased advertising due to COVID-19, and IAC recorded impairments during the fiscal year ended December 31, 2020 related to IAC’s desktop business and certain securities (see “Information About IAC After the Spin-off  — Management’s Discussion and Analysis of Financial Condition and Results of Operations for IAC  — Overview — Consolidated and Combined Results”).

In addition, the United States and Europe, which are the first and second largest markets for IAC’s products and services, respectively, experienced significant resurgences of COVID-19, with record levels of infection being reported during the fourth quarter of 2020 and continuing into the first quarter of 2021. These resurgences and government-imposed measures to control the spread of COVID-19 continue to adversely impact IAC’s ability to conduct ordinary

course business activities for the foreseeable future, and could adversely impact employee productivity and increase operating costs. Moreover, IAC may also experience business disruption if the ordinary course operations of its contractors, vendors and/or business partners are adversely affected. Any of these measures could adversely affect IAC’s business, financial condition and results of operations.

The extent to which developments related to COVID-19 and measures designed to curb its spread continue to impact IAC’s business, financial condition and results of operations will depend on future developments, all of which are highly uncertain and many of which are beyond IAC’s control, including the speed of contagion, the development and implementation of effective preventative measures and possible treatments, the scope of governmental and other restrictions on travel, discretionary services and other activity, and public reactions to these developments. For example, these developments and measures have resulted in rapid and adverse changes to the operating environment in which IAC does business, as well as significant uncertainty concerning the near and long term economic ramifications of the COVID-19 outbreak, which have adversely impacted IAC’s ability to forecast its results and respond in a timely and effective manner to trends related to COVID-19. The longer the global outbreak and measures designed to curb the spread of COVID-19 continue to adversely affect levels of consumer confidence, discretionary spending and the willingness of consumers to interact with other consumers, vendors and service providers face-to-face (and in turn, adversely affect demand for IAC’s various products and services), the greater the adverse impact is likely to be on IAC’s business, financial condition and results of operations and the more limited IAC’s ability will be to try and make up for delayed or lost revenues.

The COVID-19 outbreak may also have the effect of heightening many of the other risks described in this proxy statement/consent solicitation statement/prospectus. IAC will continue to evaluate the nature and extent of the impact of the COVID-19 outbreak on its business, financial condition and results of operations.

Furthermore, because COVID-19 did not begin to impact IAC’s results until late in the first quarter of 2020, any current or future impacts may not be directly comparable to any historical periods and are not necessarily indicative of any future impacts that COVID-19 may have on IAC’s results. The impact of COVID-19 on IAC’s revenues and expenses may also fluctuate differently over the duration of the pandemic.

IAC may not be able to protect its systems, technology and infrastructure from cyberattacks and cyberattacks experienced by third parties may adversely affect IAC.

IAC is regularly under attack by perpetrators of malicious technology-related events, such as the use of botnets, malware or other destructive or disruptive software, distributed denial of service attacks, phishing, attempts to misappropriate user information and account login credentials and other similar malicious activities. The incidence of events of this nature (or any combination thereof) is on the rise worldwide. While IAC continuously develops and maintains systems designed to detect and prevent events of this nature from impacting its systems, technology, infrastructure, products, services and users, has invested (and continue to invest) heavily in these efforts and related personnel and training and deploys data minimization strategies (where appropriate), these efforts are costly and require ongoing monitoring and updating as technologies change and efforts to overcome preventative security measures become more sophisticated. Despite these efforts, some of IAC’s systems have experienced past security incidents, none of which had a material adverse effect on its business, financial condition and results of operations, and IAC could experience significant or material events of this nature in the future.

Any event of this nature that IAC experiences could damage its systems, technology and infrastructure and/or those of its users, prevent IAC from providing its products and services, compromise the integrity of its products and services, damage its reputation, erode IAC’s brands and/or be costly to remedy, as well as subject IAC to investigations by regulatory authorities, fines and/or litigation that could result in liability to third parties. Even if IAC does not experience such events firsthand, the impact of any such events experienced by third parties upon which IAC relies and with which IAC contracts for various products and services could have a similar effect. No assurances can be provided that IAC will not experience future events involving third-party service providers that could adversely affect IAC’s business, financial conditions and results of operations in a significant or material manner. IAC may not have adequate insurance coverage to compensate for losses resulting from any of these events. If IAC (or any third-party with which it does business or

otherwise relies upon) experience(s) an event of this nature, IAC’s business, financial condition and results of operations could be adversely affected.

If personal, confidential or sensitive user information is breached or otherwise accessed by unauthorized persons, it may be costly to mitigate and IAC’s reputation could be harmed.

IAC receives, processes, stores and transmits a significant amount of personal, confidential and/or sensitive user and subscriber information and, in the case of certain of its products and services, enables users and subscribers to share their personal information with each other. While IAC continuously develops and maintains systems designed to protect the security, integrity and confidentiality of this information (and only engages third-parties to store this information who do the same), IAC cannot guarantee that inadvertent or unauthorized use or disclosure will not occur or that third parties will not gain unauthorized access to this information. When such events occur, IAC may not be able to remedy them, it may be required by law to notify regulators and impacted individuals and it may be costly to mitigate the impact of such events and to develop and implement protections to prevent future events of this nature from occurring. When breaches of security (IAC’s security or that of any third-party it engages to store such information) occur, IAC could face governmental enforcement actions, significant fines, litigation (including consumer class actions) and the reputation of its brands and business could be harmed, any or all of which could adversely affect IAC’s business, financial condition and results of operations. In addition, if any of the search engines, digital app stores or social media platforms through which IAC markets, distributes and monetizes its products and services were to experience a breach, third parties could gain unauthorized access to personal data about IAC’s users and subscribers, which could indirectly harm the reputation of IAC’s brands and business and, in turn, adversely affect IAC’s business, financial condition and results of operations.

The processing, storage, use and disclosure of personal data could give rise to liabilities and increased costs.

IAC receives, transmits and stores a large volume of personal information and other user and subscriber data (including private content, such as videos and correspondence) in connection with the processing of search queries, the provision of online products and services generally and the display of advertising on its various properties. The manner in which IAC shares, stores, uses, discloses and protects this information is determined by the respective privacy and data security policies of its various businesses, as well as federal, state and foreign laws and regulations and evolving industry standards and practices, which are changing, and in some cases, inconsistent and conflicting and subject to differing interpretations. In addition, new laws, regulations, standards and practices of this nature are proposed and adopted from time to time. For a description of laws, regulations and rules concerning the processing, storage and use of disclosureof personal data, see “Information About IAC After the Spin-off — Government Regulation.”

While IAC believes that it complies with applicable privacy and data protection policies, laws and regulations and industry standards and practices in all material respects, it could still be subject to claims of non-compliance that it may not be able to successfully defend and/or may result in significant fines and penalties. Moreover, any non-compliance or perceived non-compliance by IAC (and/or any third party IAC engages) or any compromise of security that results in unauthorized access to (or use or transmission of) personal information could result in a variety of claims against IAC, including governmental enforcement actions, significant fines, litigation (including consumer class actions), claims of breach of contract and indemnity by third parties and adverse publicity. When such events occur, IAC’s reputation could be harmed and the competitive positions of its various brands and businesses could be diminished, which could adversely affect its business, financial condition and results of operations. Additionally, to the extent multiple U.S. state-level (or European Union member-state level) laws are introduced with inconsistent or conflicting standards and there is no federal or European Union regulation to preempt such laws, compliance could be even more difficult to achieve and IAC’s potential exposure to the risks discussed above could increase.

Lastly, ongoing compliance with existing (and compliance with future) privacy and data protection laws worldwide could be costly. The devotion of significant costs to compliance (versus to the development of products and services) could result in delays in the development of new products and services, IAC ceasing to provide problematic products and services in existing jurisdictions and IAC being prevented from introducing products and services in new and existing jurisdictions, any or all of which could adversely affect IAC’s business, financial condition and results of operations.

The success of IAC depends, in part, on the integrity, quality, efficiency and scalability of its systems, technology and infrastructure, and those of third parties.

IAC relies on its systems, technology and infrastructure to perform well on a consistent basis. From time to time in the past IAC has experienced (and in the future IAC may experience) occasional interruptions that make some or all of this framework and related information unavailable or that prevent IAC from providing products and services; any such interruption could arise for any number of reasons. IAC also relies on third-party data center service providers and cloud-based, hosted web service providers, as well as third-party computer systems and a variety of communications systems and service providers in connection with the provision of its products and services generally, as well as to facilitate and process certain payment and other transactions with users. IAC has no control over any of these third parties or their operations and the interruption of any of the services provided by these parties could prevent IAC from accessing user and subscriber information and providing products and services.

The framework described above could be damaged or interrupted at any time due to fire, power loss, telecommunications failure, natural disasters, acts of war or terrorism, acts of God and other similar events or disruptions. Any event of this nature could prevent IAC from providing its products and services at all (or result in the provision of its products on a delayed or interrupted basis) and/or result in the loss of critical data. While IAC and the third-parties upon whom it relies have certain backup systems in place for certain aspects of IAC’s and their respective frameworks, none of these frameworks are fully redundant and disaster recovery planning is not sufficient for all eventualities. In addition, IAC may not have adequate insurance coverage to compensate for losses from a major interruption. When such damages, interruptions or outages occur, IAC’s reputation could be harmed and the competitive positions of its various brands and businesses could be diminished, any or all of which could adversely affect IAC’s business, financial condition and results of operations.

IAC also continually works to expand and enhance the efficiency and scalability of its framework to improve the consumer experience, accommodate substantial increases in the number of visitors to its various platforms, ensure acceptable load times for its various products and services and keep up with changes in user and subscriber preferences. If IAC does not do so in a timely and cost-effective manner, user and subscriber experiences and demand across its brands and businesses could be adversely affected, which could adversely affect IAC’s business, financial condition and results of operations.

IAC depends on its key personnel.

The future success of IAC will depend upon its continued ability to identify, hire, develop, motivate and retain highly skilled, diverse and talented individuals worldwide, particularly in the case of senior management. Competition for well-qualified employees across IAC and its various businesses has been (and will continue to be intense and IAC must attract new (and retain existing) employees to compete effectively. While IAC has established programs to attract new (and retain existing) employees, it may not be able to attract new (or retain existing) key and other employees in the future. In addition, if IAC does not ensure the effective transfer of knowledge to successors and smooth transitions (particularly in the case of senior management) across its various businesses, IAC’s business, financial condition and results of operations could be adversely affected.

Risks Relating to SpinCo and the Vimeo Business Following the Spin-off

Vimeo has a limited operating history as a pure software-as-a-service (“SaaS”) company.

In its 16-year history, Vimeo has explored or experimented with various service offerings, including a proprietary streaming service, and various monetization methods, including advertising, transactions and subscriptions. While Vimeo has offered subscription plans since 2008, Vimeo did not decide to focus primarily on SaaS offerings until 2017. In addition, Vimeo has only operated an enterprise-focused sales operation since 2017, when it acquired Livestream.

Mr. Diller and certain members of his family will be able to exercise significant influence over the composition of SpinCo’s Board of Directors, matters subject to stockholder approval and SpinCo’s operations.

As of [·], Mr. Diller, his spouse, Diane von Furstenberg, and his stepson, Alexander von Furstenberg, collectively held shares of IAC Class B common stock and IAC common stock that represented approximately [·]% of the total outstanding voting power of IAC (based on the number of shares of IAC common stock outstanding and entitled to vote as of [·]) and they will collectively hold shares of SpinCo Class B common stock and SpinCo common stock that are expected to represent approximately [·]% of the total outstanding voting power of SpinCo following the Spin-off. The IAC shares are also subject to a voting agreement with Mr. Levin, IAC’s Chief Executive Officer, and following the Spin-off, a corresponding voting agreement with respect to the SpinCo shares will be entered into among the parties to the existing voting agreement.

As a result of SpinCo securities that will be beneficially owned by these individuals following the completion of the Spin-off, such individuals will be, collectively, in a position to influence (subject to SpinCo’s organizational documents and Delaware law), the composition of SpinCo’s Board of Directors and the outcome of corporate actions requiring shareholder approval, such as mergers, business combinations and dispositions of assets, among other corporate transactions. The disparity between the voting power of the holders of the Vimeo Class B common stock and the corresponding economic ownership position could also create incentives for such holders to either seek to obtain benefits for themselves (in the form of compensation or other contractual benefits, for example) in a form not available to all stockholders on a pro rata basis. In addition, this concentration of investment and voting power could discourage others from initiating a potential merger, takeover or other change of control transaction that may otherwise be beneficial to SpinCo and its shareholders, which could adversely affect the market price of SpinCo securities.

In addition, the holders of the Class B common stock could sell all or a portion of those shares to a third party, which could result in the purchaser obtaining significant influence over Vimeo, the composition of Vimeo’s Board of Directors, matters subject to stockholder approval and Vimeo’s operations, without consideration being paid to holders of shares of Vimeo common stock, and without holders of shares of Vimeo common stock having a right to consent to the identity of such purchaser.

Vimeo has a history of losses.

Vimeo has not earned a profit in any full fiscal year since its inception, and it cannot be certain as to when SpinCo will achieve or maintain profitability. Because the market for SaaS video services is rapidly evolving and highly competitive, SpinCo must continue to invest in research and development. If such investment does not allow SpinCo to scale or attract and retain users and subscribers, SpinCo will not be able to achieve profitability.

Vimeo’s recent and rapid growth may not be indicative of future performance.

The growth Vimeo experienced during the first nine months of 2020 may be partly or largely attributable to increased demand for online video due to social distancing undertaken in response to the COVID-19 pandemic. If the COVID-19 pandemic ends and the level of demand for online video returns to pre- pandemic levels, then the growth rates Vimeo achieved in 2020 may not be indicative of growth rates in future periods. In addition, a prolonged economic downturn caused by the COVID-19 pandemic could ultimately reduce demand by reducing businesses’ ability to pay for Vimeo’s services.

SpinCo’s growth and profitability depend upon a wide variety of factors, some of which are out of SpinCo’s control.

Whether SpinCo can grow its revenue and ultimately achieve profitability will depend upon a number of factors including:

Vimeo’s total addressable market may prove to be smaller than it expects.

While Vimeo believes, based upon internal data, that every small and midsized business and every larger enterprise will need an online video presence to succeed, the number of entities that are willing and able to pay fees for software-based video services may not be as large as it expects. Vimeo has not conducted research by a third party to validate its data and thesis.

SpinCo has no experience as a standalone public company.

SpinCo’s executive officers do not have experience as officers of a publicly traded company. Transitioning to a public company may distract management from its focus on Vimeo’s core business. In addition, both the Spin-off and registration of SpinCo securities will require SpinCo to incur new significant new expenses, particularly in the areas of finance, legal and human resources, that were previously incurred by IAC.

SpinCo may need additional funding as SpinCo continues to invest in research and development and expand internationally.

SpinCo may need to raise additional funds by way of a primary offering of shares of SpinCo common stock, which would dilute existing shareholders. SpinCo may also raise additional funds through additional borrowings. To obtain such funding, SpinCo may need to pledge assets and agree to certain financial covenants.

Vimeo may not have the right product/market fit.

Vimeo’s business depends upon attracting new subscribers and retaining existing ones. To do so, it must provide products with an attractive value proposition. Vimeo may fail to do that if it:

Vimeo may not be able to convert its free users into subscribers.

An essential part of Vimeo’s strategy for attracting subscribers depends upon offering basic services for free and converting a certain portion of its free users into subscribers over time. While a majority of Vimeo subscribers began as free users, only a small percentage of free users become paying users over time. Vimeo’s ability to convert users into subscribers at this or a higher rate may not materialize if:

If Vimeo’s efforts to convert free users into subscribers do not succeed, it will have to rely more heavily on paid marketing efforts to acquire new subscribers and therefore achieve growth. Such a shift would cause Vimeo to incur higher costs in acquiring users, which would reduce its profits.

Competition in Vimeo’s market is intense.

Vimeo operates in a highly competitive market. It competes with both large social media networks and a variety of niche software providers for business customers. Large social media networks provide their services for free and offer features such as a large built-in audience, social media features and the ability to monetize through advertising. Niche providers include large, well-funded companies and new entrants. Either may be able to provide more compelling features than Vimeo within their area of focus. In addition, Vimeo expects that more competitors will emerge given the relatively low barriers to entry for software- based video creation applications, particularly mobile-based applications. New competitors could take the form of start-ups or large, well-funded companies that already operate in markets adjacent to Vimeo.

Vimeo may not be able to scale its business effectively.

Vimeo may not be able to capitalize on the market’s demand for video if it cannot scale its operations. For example, Vimeo might experience delays in onboarding new customers and responding to increased customer support tickets, and

it may not be able to handle increased loads on its servers during peak times. All of these things would result in missed opportunities or user and subscriber frustration that could negatively affect user and subscriber growth and retention.

Vimeo may experience service interruptions.

Vimeo typically does not provide 100% uptime across its video services in any given month. This may be due to technical errors (bugs), human error (by employees and contractors), interruptions experienced by key vendors (such as cloud-based service or payment providers), higher than anticipated traffic and/or cyberattacks. Interruptions in key aspects of Vimeo’s video services (notably, video delivery and payment processing) could result in lost business, credits payable to subscribers with service level agreements, increased user and subscriber support tickets, remediation costs and increased subscriber churn (lost renewals). In severe cases, Vimeo could face litigation or reputational risk, particularly if an interruption occurs during a high-profile event.

Hosting and delivery costs may increase unexpectedly.

Hosting and delivery costs comprise the largest component of Vimeo’s cost of goods sold and thus materially influences its gross margin. These costs could increase unexpectedly if Vimeo experiences rapid growth over a short period of time (either in terms of users and subscribers or bandwidth consumed), it fails to address subscribers who use more bandwidth than its plans permit (e.g., either by failing to charge them overage fees or by failing to limit their bandwidth) or Vimeo fails to distribute increased bandwidth across its content delivery network (CDN) vendors in a cost-optimal manner by, for example, moving traffic to the lowest-cost provider. Vimeo may not be able to pass these costs onto subscribers.

The success of Vimeo will depend upon its continued ability to identify, hire, develop, motivate and retain highly skilled individuals worldwide.

In order to build and scale its business, Vimeo will need to further increase its employee base, particularly in the areas of engineering, product development, sales (domestically and internationally), customer support and shared services. Vimeo’s ability to attract and retain talent and to fully experience the benefits of that talent depends upon:

Vimeo’s compensation packages may not be sufficient.

While Vimeo has established compensation programs (which include cash compensation, equity-based programs and other benefits) to attract and retain employees, these compensation arrangements may not be sufficient in the highly competitive labor market in which it participates. Large competitors and non- competitors in the technology space may offer compensation arrangements that may significantly exceed those that Vimeo is able to offer. If Vimeo fails to provide competitive compensation arrangements, it may fail to attract and retain talent. In addition, if Vimeo does not

ensure the effective transfer of knowledge to successors and smooth transitions (particularly in the case of senior management), its business may be adversely affected. On the other hand, if Vimeo increases compensation levels in a significant way in order to compete for talent, its profitability could suffer.

Vimeo may fail to attract or retain employees for issues that negatively impact Vimeo’s image.

Vimeo’s ability to attract and retain employees could also be adversely affected by issues that negatively impact its image, such as incidents of actual or perceived discrimination, controversial business decisions, including decisions about user content, and issues with the quality of our products (such as bugs or interruptions in services, among other issues).

Vimeo’s success depends, in substantial part, on its ability to market, distribute and monetize its products and services through search engines, digital app stores and social media platforms.

The marketing, distribution and monetization of Vimeo’s products and services depend on its ability to cultivate and maintain cost-effective and otherwise satisfactory relationships with search engines, digital app stores and social media platforms, in particular, those operated by Apple, Google and Facebook. These platforms could decide not to market and distribute some or all of Vimeo’s products and services, change their terms and conditions of use at any time (and without notice), favor their own products and services over those of Vimeo and/or significantly increase their fees. While Vimeo expects to maintain cost-effective and otherwise satisfactory relationships with these platforms, no assurances can be provided that Vimeo will be able to do so and its inability to do so in the case of one or more of these platforms could have a material adverse effect on Vimeo’s business, financial condition and results of operations.

In particular, as consumers increasingly access Vimeo’s products and services through applications (both mobile and desktop), Vimeo increasingly depends upon the Apple App Store, Google Play Store and Google’s Chrome Web Store to distribute its mobile and desktop browser applications. Both Apple and Google have broad discretion to change their respective terms and conditions applicable to the distribution of Vimeo’s applications, including those relating to the amount of (and requirement to pay) certain fees associated with purchases facilitated by Apple and Google through Vimeo’s applications, their ability to interpret their respective terms and conditions in ways that may limit, eliminate or otherwise interfere with Vimeo’s ability to distribute its applications through their stores, the features Vimeo may provide in its products and services, Vimeo’s ability to access information about its subscribers and users that they collect and the manner in which Vimeo markets in-app products. Apple or Google could also make changes to their operating systems or payment services that could negatively affect Vimeo. No assurances can be provided that Apple and/or Google will not interpret their respective terms and conditions in the manner described above and to the extent either or both of them do so, Vimeo’s business, financial condition and results of operations could be adversely affected.

While some of Vimeo’s mobile applications are generally free to download from the Apple App and Google Play Stores, many of them are subscription-based. While Vimeo determines the prices at which these subscriptions are sold, currently, all related purchases must be processed through the in-app payment systems provided by these stores, for which Vimeo pays these stores a meaningful share (generally 30% for the first 12 months, and 15% thereafter) of the related revenue it receives. Given the increasing distribution of its mobile applications through digital app stores and strict in-app payment system requirements, Vimeo may need to offset increased digital app store fees by decreasing traditional marketing expenditures as a percentage of revenue, increasing user volume or monetization per user or engaging in other efforts to increase revenue or decrease costs generally, or its business, financial condition and results of operations could be adversely affected.

In addition to Vimeo’s current branded apps, one of the services Vimeo offers subscribers (for its Vimeo OTT service) is the ability to reach their viewers using apps on various platforms’ operating systems, including those of Apple, Google, Amazon Fire, Roku, and Microsoft’s Xbox. These apps use Vimeo technology but feature the subscriber’s branding. Changes in platform policies may make it more difficult or expensive for SpinCo to release and maintain its subscribers’ apps.

Vimeo depends on integrations with third parties to enable key features of its video services and to acquire new subscribers.

Some of Vimeo’s video services are integrated, typically through application programming interfaces (“APIs”), with numerous third parties, including companies that compete with Vimeo. For example, Vimeo provides a “publish to social” feature which allows its users and subscribers to publish their videos to their accounts on Facebook and/or YouTube. This type of feature makes Vimeo’s video services valuable because it effectively allows Vimeo to serve as a hub for managing all of the videos for a given user or subscriber across numerous platforms. If platforms change their policies to no longer permit this feature, Vimeo’s video services would be less attractive to its users and subscribers.

Vimeo depends on key third-party vendors to provide core services.

Vimeo depends on third-party vendors to, among other things, provide customer support, develop software, host videos uploaded by its users, transcode videos (compressing a video file and converting it into a standard format optimized for streaming), stream videos to viewers and process payments. Specifically, Google Cloud Service (“GCS”) provides Vimeo with hosting and transcoding services, Amazon S3 provides Vimeo with hosting services and Vimeo uses multiple CDNs to deliver traffic worldwide. Certain of these third-party vendors have experienced outages in the past that have caused key Vimeo video services to be unavailable for several hours. Vimeo does not have backup systems for GCS or Amazon S3. Consequently, outages in those services materially affect its video services. Outages may expose Vimeo to having to offer credits to subscribers, loss of subscribers and reputational damage. Vimeo may not be able to full offset these losses with any credits it might receive from its vendors.

Vimeo depends on search engines and social media networks for traffic.

Vimeo depends on search engines and social media networks to acquire traffic to its website. These third parties have the ability to influence who reaches Vimeo’s website and video services through algorithmic search rankings and other policy decisions, which are subject to frequent change. Some of these third parties or their affiliates compete with Vimeo and may have an incentive to favor their competing services over Vimeo’s. In the past, traffic to Vimeo’s website and video services has been negatively impacted as a result of certain policy changes by both search engines and social media networks.

Vimeo depends on internet service providers (“ISPs”) to deliver traffic to end users and subscribers.

For Vimeo’s video services to operate, users and subscribers must have a connection to the internet. Typically, Vimeo users and subscribers access the internet through a wireline or wireless data service offered by ISPs such as AT&T, Comcast and/or Verizon. There is currently no federal regulation in the U.S. limiting the practices that ISPs may use to impact data flowing from websites and online applications to users and subscribers of online products and services generally. As a result, ISPs could discriminate against data that Vimeo delivers to users or subscribers (or data its users upload to it) by blocking it outright, slowing it down or otherwise degrading its quality vis-à-vis competing traffic. ISPs could also cause their customers to favor competing services by “zero rating” traffic to and from Vimeo competitors (in other words, not counting competitor traffic against an ISP customer’s data caps) but declining to zero rate its traffic. These practices could make Vimeo less attractive as a provider of video services. Alternatively, Vimeo may have to pay fees to ISPs to maintain parity with competitors, which could adversely affect its profitability.

Vimeo’s business involves hosting large quantities of user content.

Vimeo does not (and cannot undertake to) review all or even a significant portion of the videos uploaded to its platform to ensure that the videos do not violate any law or third-party rights. Some of the videos uploaded to Vimeo’s platform will invariably violate a third party’s rights or a law, rule or regulation, and if so, Vimeo could, in turn, face lawsuits, liability and negative publicity for hosting such content.

Vimeo has been sued for hosting content that allegedly infringed on a third-party copyright.

Vimeo cannot guarantee that it will be shielded from third-party copyright infringement lawsuits and related liability for hosting user and subscriber content by laws such as the online safe harbor provisions of the Digital Millennium Copyright Act of 1998 (“DMCA”), which are intended to limit the liability of online providers with respect to user- and subscriber-uploaded content. In addition, even if Vimeo ultimately succeeds in demonstrating that the DMCA limits its liability, litigating these issues is costly and time- consuming. For details regarding pending lawsuits of this nature, see “Information About SpinCo After the Spin-Off — Legal Proceedings.”

Some countries outside of the United States have laws that, like the DMCA, limit the copyright infringement liability of service providers. However, these laws may impose different requirements upon Vimeo and may not protect it to the same degree as the DMCA. Vimeo cannot guarantee that it will be compliant with foreign requirements. For example, as described in the section entitled “Information About SpinCo After the Spin-Off — Legal Proceedings”, we have been sued in Italy for the copyright infringement of our users.

If the laws limiting Vimeo’s liability for user and subscriber copyright infringement are changed, either by amendment, regulatory action or judicial interpretation, Vimeo could face increased compliance costs and increased risk of liability for copyright infringement. In 2020, Congress held hearings on whether the DMCA ought to be amended. In 2018, the European Union passed Article 17 to revise the EU’s existing framework for limiting the liability of service providers for copyright infringement. EU member state laws that implement Article 17 (which must be done by July 2021) may require Vimeo to undertake new and costly screening activities or to obtain costly licenses from rights holders or both.

Vimeo may face liability for hosting a variety of tortious or unlawful materials.

In the United States, Section 230 of the Communications Decency Act generally limits Vimeo’s liability for hosting tortious and otherwise illegal content. The immunities conferred by Section 230 could be narrowed or eliminated through amendment, regulatory action or judicial interpretation. In 2018, Congress amended Section 230 to remove immunities for content that promotes or facilitates sex trafficking and prostitution. In 2020, various members of Congress introduced bills to further limit Section 230, and a petition was filed by a Department of Commerce entity with the Federal Communications Commission to commence a rulemaking to further limit Section 230.

Laws like Section 230 generally do not exist outside of the United States, and some countries have enacted laws that require online content providers to remove certain pieces of content within short time frames. For example, in 2020, France enacted a law requiring covered social media networks to remove terror content within one hour upon receiving notice. If Vimeo fails to comply with such laws, it could be subject to prosecution or regulatory proceedings. In addition, some countries may decide to ban Vimeo’s service based upon a single piece of content. Vimeo has been subject to temporary bans in certain countries, including India, Russia and Turkey, for hosting content that those governments determined to be illegal.

Vimeo may also face liability when it removes content and accounts that it believes are violating its acceptable use policy, and Vimeo has been sued in the past for certain content-removal decisions. While Vimeo believes that Section 230 allows it to restrict or remove certain categories of content, its protections may not always end a lawsuit at an early stage, potentially resulting in costly and time-consuming litigation.

Vimeo has faced negative publicity for removing, or declining to remove, certain content, regardless of whether such content violated any law.

Individuals and groups may upload controversial content to Vimeo’s platform. Removing or failing to remove such content may result in negative publicity, which could harm its efforts to attract and retain users and subscribers. Vimeo has also faced criticism from users and subscribers for removing content and terminating accounts in compliance with the DMCA.

Vimeo collects, stores, and processes large amounts of video content (including videos that are not intended for public consumption) and personal information of its users and subscribers.

Vimeo collects, stores and processes large amounts of video content (including videos that are not intended for public consumption) and personal information of its users and subscribers. Vimeo also shares such information, where appropriate, with third parties that help it operate its business. Despite Vimeo’s efforts, it may fail to properly secure its systems and its user and subscriber data. This could be caused by technical issues (bugs), human error or internal or external malfeasance, and could lead to unauthorized disclosure of data, unauthorized changes or data losses. For example, Vimeo routinely receives reports from security researchers regarding potential vulnerabilities in its applications. The existence of such vulnerabilities, if undetected or detected but not remediated, could result in unauthorized access to Vimeo systems or the data of Vimeo users and subscribers.

A data breach could expose Vimeo to regulatory actions and litigation. Depending on the circumstances, Vimeo may be required to disclose a suspected breach to regulators, affected individuals and/or the public. This could lead to regulatory actions, including the possibility of fines, class-action or traditional litigation by affected individuals, reputational harm, costly investigation and remedial efforts, the triggering of indemnification obligations under data-protection agreements with subscribers, vendors, and partners and/or higher premiums for cyber insurance.

Vimeo has been the target of cyberattacks by malicious actors.

Malicious actors may use a variety of techniques to interfere with or gain access to Vimeo’s systems, including hacking (exploiting software vulnerabilities), social engineering (gaining access to internal systems through employees), malware, ransomware and denial of service attacks (sending large quantities of traffic in an attempt to overload our servers). Vimeo may fail to adequately defend against such attacks. If not prevented or mitigated, cyberattacks could result in a data breach, loss of data and business interruption, any of all of which could adversely affect Vimeo’s business.

Some malfeasance could also be directed at the accounts of Vimeo users and subscribers (as opposed to Vimeo’s systems). For example, Vimeo has experienced cases where user and subscriber accounts were compromised due to password guessing or credential stuffing arising from a breach of account credentials on third-party services. These situations take time to remediate and are frustrating for Vimeo users and subscribers, some of whom may blame Vimeo for the relevant cyberattack.

Vimeo may fail to comply with applicable privacy laws.

Vimeo is subject to numerous laws governing the use of personal information, including sensitive personal information, such as financial information and demographic information. Vimeo has been sued for violating the Illinois Biometric Protection Act, which regulates the collection and use of biometric information (see the section entitled “Information About SpinCo After the Spin-Off — Legal Proceedings”). The failure to comply with applicable privacy laws could lead to regulatory actions, including the possibility of fines, class-action or traditional litigation, reputational harm and/or costly investigation and remedial efforts.

Compliance obligations imposed by new privacy laws or industry practices may adversely affect Vimeo’s business.

New laws could restrict Vimeo’s ability to conduct marketing (by, for example, restricting the emailing or targeting users or use certain technologies like artificial intelligence). Similarly, private-market participants may deploy technologies or require certain practices that limit Vimeo’s ability to obtain or use certain information about its users and subscribers. For example, Google has indicated that it will ultimately phase out the use of cookies to track users of its search services in future versions of its Chrome web browser, and Apple has indicated that a future update to its iOS mobile operating system will require app developers to obtain opt-in consent before tracking users of its various services. If these types of changes are implemented, Vimeo’s ability to determine how its users and subscribers are using its video services and to use targeted advertising in a cost-effective manner may be limited.

Vimeo’s ability to transfer personal information to the United States may be restricted.

Some countries outside of the United States (particularly those states that are members of the European Union) may limit the transfer of data regarding their residents to other countries. Such laws have the potential to adversely affect Vimeo’s business. For example, prior to June 2020, many United States companies (including Vimeo) participated in the U.S.-EU and U.S.-Swiss “Privacy Shield” program, which provided a basis on which to transfer personal information from the EU and Switzerland to the U.S. In June 2020, the EU High Court of Justice determined that the program did not adequately protect EU residents’ privacy rights. Vimeo did not rely solely on the Privacy Shield program to transfer data from the EU to the U.S. and has continued to transfer data from the EU to the U.S. under other legal bases. If those other legal bases were to be invalidated, Vimeo may have to stop transferring personal data from the EU. This could require Vimeo to host personal EU data within the EU and not transfer it outside of the EU. Should this occur, it would face higher costs and operational challenges, which could adversely affect its business and gross margin.

Vimeo depends on vendors to process transactions.

Vimeo relies on payment card transactions to earn revenue from its self-serve subscription plans. Vimeo does not directly process credit cards. Instead, it relies exclusively on third-party vendors to process such payments. While this avoids it having to acquire credit card numbers in the first instance, it makes Vimeo dependent on payment vendors such as credit card processing companies. These vendors have experienced interruptions and errors that have caused Vimeo to lose revenue.

Vimeo may fail to comply with laws regulating subscriptions and free trials.

Subscriptions to Vimeo’s video services automatically renew unless the subscriber cancels the subscription before the end of the current period, and Vimeo often provides free or discounted trial periods. There are various laws regulating such offers, such as the U.S. Restore Online Shoppers Confidence Act (“ROSCA”) and analogous state-level laws. Non-compliance could result in voided contracts, lost revenue, damages and class action or traditional lawsuits.

Changes in laws or industry practices concerning subscription services may have a negative impact on renewal rates.

New laws or interpretations of existing laws may impose obligations that make it difficult or impossible to implement the automatic renewal of subscription to Vimeo’s video service. For example, if Vimeo were required to obtain express opt-in consent for automatic renewal of its video service and were not permitted to deny transactions to people who fail to opt-in, the related rate of renewal would likely decrease substantially. Similarly, private entities involved in payment collection and processing may also effectively regulate subscriptions to Vimeo’s video services. Failure to comply with these rules could result in Vimeo’s inability to process automatic renewals. Finally, Vimeo has no control over policy decisions by app platforms regarding automatic renewals. Policy changes by app platforms could adversely impact Vimeo’s renewal rates for subscription to its video services, and in turn, its business.

The sale of Vimeo’s products are subject to a variety of sales, use and value-added taxes, both in the United States and worldwide.

In 2018, in South Dakota v. Wayfair, the United States Supreme Court held that states may charge taxes on purchases made by their residents from out-of-state sellers who have no physical nexus to the state. As a result of this decision, Vimeo is subject to taxes in states where one or more of its services is taxable, the state permits taxation based upon economic nexus, and Vimeo meets certain thresholds. Vimeo is also, as before, subject to taxes in states in which it maintains a physical presence. Vimeo cannot guarantee complete tax compliance. Vimeo is currently involved in one voluntary disclosure proceeding in one United States state concerning the non-payment of a certain tax.

Vimeo may be subject to digital services taxes (“DSTs”) in a variety of countries.

A DST typically levies a tax rate on a company’s total revenue derived from a country from covered digital activities, which may include online advertising, online transactions or operating certain types of online businesses, such as a social media network. Countries including the UK and France have passed DST laws and more countries are

considering them. Depending on the scope of the law and its revenue thresholds, some of Vimeo’s revenue could be in scope for DST taxation. Vimeo may or may not be able to pass along the cost of such additional taxes to subscribers in the taxing countries.

The novel coronavirus that causes the disease known as COVID-19 has caused a global health crisis that has caused significant economic and social disruption.

The COVID-19 pandemic has prompted governments in affected regions to implement measures designed to curb the spread of the virus, such as social distancing, government-imposed quarantines and lockdowns, travel bans and other public health safety measures. Even where such measures have not been taken, individuals and businesses have changed their behavior. Collectively, these measures have resulted in significant social disruption and have had (and are likely to continue to have) an adverse effect on economic conditions, consumer confidence and spending and business investment, all of which could affect our business.

While certain of these measures have increased the demand for online video services, a prolonged economic downturn could ultimately reduce demand for these services. For example, small and midsized businesses that have been severely impacted by the pandemic may need to wind down their operations or reduce their spending. If that occurs, Vimeo may see a reduction in first-time subscribers and renewals.

In addition, as a result of the pandemic, the ability of Vimeo to conduct ordinary course business activities has been (and may continue to be) impaired for an indefinite period of time. For example, Vimeo has taken several precautions that could adversely impact employee productivity, such as requiring or allowing employees to work remotely, imposing travel restrictions and temporarily closing office locations.

Vimeo may experience increased operating costs as it gradually resumes normal operations. This may require enhanced preventative measures, including with respect to real estate, compliance and insurance- related expenses. Moreover, Vimeo may also experience business disruption if the operations of its contractors, vendors or business partners are adversely affected.

The extent to which developments related to the COVID-19 pandemic and measures designed to curb its spread continue to impact Vimeo’s business will depend on future developments, all of which are highly uncertain and many of which are beyond Vimeo’s control, including the speed of transmission, the development and rollout of effective vaccines and possible treatments, the scope of governmental and other restrictions on travel and other activities and public reactions to these developments.

Vimeo’s historical financial information, and SpinCo’s pro forma financial information, as well as certain Vimeo operating metrics, may not be indicative of SpinCo’s future results

Vimeo’s historical financial information and SpinCo’s pro forma financial information included in this proxy statement/consent solicitation statement/prospectus may not reflect what Vimeo’s results of operations, financial position and cash flows would have been as an independent company during the periods presented, or be indicative of what SpinCo’s results of operations, financial position and cash flows may be in the future.

In addition, the SpinCo pro forma financial information included in this proxy statement/consent solicitation statement/prospectus is based, in part, upon a number of estimates and assumptions. These estimates and assumptions may prove not to be accurate, and, accordingly, SpinCo’s pro forma financial information should not be assumed to be indicative of what Vimeo’s financial condition or results of operations actually would have been as a separate company and may not be a reliable indicator of what SpinCo’s financial condition or results of operations may be in the future.

Risks Relating to the Vimeo Merger

In addition to the following information regarding risks and uncertainties relating to the Vimeo merger, please see “— Risks Relating to IAC Securities and Vimeo Securities Following the Spin-off,” for important information regarding

the risks and uncertainties relating to SpinCo common stock following the Spin-off, which will also apply to SpinCo common stock following the Vimeo Merger.

The Vimeo merger is subject to certain closing conditions (including the completion of the Spin-off) that, if not satisfied or waived, will result in the Vimeo merger not being completed.

The completion of the Vimeo merger is subject to the satisfaction or waiver of the following conditions: (a) the receipt of the Vimeo stockholder approval; (b) the completion of the Spin-off; (c) no law having been enacted, or order or injunction having been issued or granted, by a governmental entity of competent jurisdiction that prohibits the completion of the Vimeo merger; (d) no appraisal rights having been asserted by any holder of Vimeo capital stock, which rights have not been lost or abandoned; (e) the effectiveness of the registration statement of which this proxy statement/consent solicitation statement/prospectus forms a part; and (f) the approval for listing on any nationally recognized securities exchange on which shares of SpinCo common stock are being listed in the Spin-off of the shares of SpinCo common stock to be issued to Vimeo stockholders in connection with the Vimeo merger. Some of the conditions to the completion of the Vimeo merger are outside of the control of IAC, SpinCo and/or Vimeo. If any condition to the completion of the Vimeo merger is not satisfied or waived, including if the IAC board of directors determines to abandon the Spin-off, the Vimeo merger will not be completed. For a discussion of the conditions to the completion of the Vimeo merger, see “The Vimeo Merger Agreement — Conditions to Completion of the Vimeo Merger.”

Vimeo will be obligated to pay certain legal and accounting fees and related expenses in connection with the Vimeo merger, whether or not the Vimeo merger is completed. In addition, Vimeo has expended, and will continue to expend, significant management resources in an effort to complete the Vimeo merger. If the Vimeo merger is not completed, Vimeo will have incurred significant costs, including the diversion of management resources, for which it will have received little or no benefit.

If the Spin-off is completed but the Vimeo merger is not completed, then IAC and SpinCo would become separate public companies, the existing third-party stockholders of Vimeo would initially remain stockholders of Vimeo, and SpinCo would own approximately 88% of Vimeo. Therefore, SpinCo and Vimeo would need to subsequently seek to implement an alternative transaction to cause or to permit the stockholders of Vimeo to exchange their ownership interests in Vimeo for an interest in SpinCo.

The Vimeo merger exchange ratio will not be known before the closing of the Vimeo merger.

The Vimeo merger exchange ratio will not be known prior to the closing of the Vimeo merger. Accordingly, Vimeo stockholders will not know with certainty prior to the consent solicitation deadline the aggregate percentages of the outstanding shares of SpinCo common stock that, following the consummation of the Vimeo merger, will initially be owned by IAC’s stockholders as a group, on the one hand, and by Vimeo’s third-party stockholders as a group, on the other hand. For further information on the Vimeo merger exchange ratio, see “The Vimeo Merger — Consideration to Vimeo Stockholders.”

There has been no public market for Vimeo capital stock and the lack of a public market may make it more difficult to determine the fair market value of Vimeo than if there were such a public market.

Vimeo is currently an indirect subsidiary of IAC, and the outstanding shares of Vimeo capital stock are held indirectly by IAC and by third-party investors. The outstanding shares of Vimeo capital stock are not traded on any public market. The lack of a public market may make it more difficult to determine the fair market value of Vimeo than if the outstanding shares of Vimeo capital stock were traded publicly. The value ascribed to Vimeo capital stock in other contexts, including in private valuations or financings, may not be indicative of the price at which the outstanding shares of Vimeo capital stock may have traded on a public market.

The market value of the SpinCo common stock that current holders of Vimeo capital stock receive in the Vimeo merger might be less than the value of the Vimeo Opco capital stock they held before the Vimeo merger.

At the effective time of the Vimeo merger, holders of Vimeo capital stock as of immediately prior to the effective time of the Vimeo merger will be entitled to receive SpinCo common stock. The price at which shares of SpinCo common stock may trade following the Vimeo merger are unpredictable. Therefore, the market value of one share of SpinCo common stock following Vimeo merger may be less than, equal to or greater than the market value of one share of Vimeo capital stock prior to the Vimeo merger.

Additionally, the value of SpinCo common stock may be negatively impacted by a number of factors, after the completion of the Vimeo merger. Some of these matters are described in these risk factors and others may or may not have been identified by IAC or SpinCo prior to the completion of the Vimeo merger, and many of them are not within IAC’s or SpinCo’s control. Should any adverse circumstances, facts, changes or effects come to pass, the value of SpinCo common stock could be less than the value of Vimeo capital stock prior to the Vimeo merger.

RECENT DEVELOPMENTS

Minority Investments in Vimeo

On November 5, 2020, Vimeo and IAC Group entered into an investment agreement (the “November 2020 Investment Agreement”) with entities affiliated with Thrive Capital (the “Thrive Entities”) and an entity affiliated with GIC Private Limited (together with the Thrive Entities, the “November Investors”), pursuant to which on November 10, 2020, the November Investors acquired an aggregate of 8,655,510 shares of Vimeo voting common stock for an aggregate purchase price of approximately $150 million, or $17.33 per share, with the transaction valuing Vimeo at an enterprise value of approximately $2.75 billion.

In connection with the investment, Vimeo, IAC Group and the November Investors entered into an amendment to the existing Vimeo shareholders agreement. The majority of the provisions of the Vimeo shareholders agreement will terminate upon the consummation of the Spin-off, other than certain confidentiality and registration rights provisions. Additionally, pursuant to the amendment to the Vimeo shareholders agreement, Vimeo and IAC Group agreed that if the Thrive Entities, together with their respective affiliates (“Thrive”), continue to own at least 75% of the shares of Vimeo voting common stock acquired by Thrive pursuant to the November 2020 Investment Agreement, and Thrive owns at least 2% of the outstanding common stock of Vimeo at the time of the Spin-off, Thrive will have the right to recommend a candidate for consideration for appointment to the initial post-Spin-off SpinCo board of directors, and SpinCo and IAC Group will consider such candidate in good faith.

In addition, the amendment to the Vimeo shareholders agreement specified certain separation principles relating to a potential Spin-off, with the November Investors’ agreement to cooperate with the Spin- off generally conditioned on compliance with such separation principles (other than departures not materially adverse to the November Investors). It is the current intention of the parties involved in the Spin- off to conform to these separation principles. The amendment to the shareholders agreement also requires that, in connection with the Spin-off, all holders of Vimeo shares, other than IAC and its affiliates, be given the benefit of the anti-dilution adjustment described in the section of this proxy statement/consent solicitation statement/prospectus entitled “The Vimeo Merger—Consideration to Vimeo Stockholders.” The Vimeo merger, if completed, is expected to comply with this requirement through the calculation of the Vimeo merger exchange ratio.

On January 25, 2021, Vimeo and IAC Group entered into investment agreements with funds and accounts advised by T. Rowe Price Associates, Inc. and entities affiliated with Oberndorf Enterprises, LLC, pursuant to which Vimeo issued and sold 6,170,934 shares of Vimeo voting common stock for $200 million, or $32.41 per share, at a $5.2 billion pre-money valuation, and 2,828,854 shares of Vimeo voting common stock for $100 million, or $35.35 per share, at a $5.7 billion pre-money valuation.

In connection with the investment, the investors became parties to the existing Vimeo shareholders agreement.

Dividend Payment

On November 5, 2020, prior to the completion of the investment pursuant to the November 2020 Investment Agreement, the Vimeo board of directors declared a cash dividend in the amount of $0.22 per share of Vimeo voting common stock and Vimeo non-voting common stock. The dividend payment date was set as November 13, 2020, and the dividend has been paid to Vimeo stockholders of record as of the close of business on November 5, 2020.

This proxy statement/consent solicitation statement/prospectus refers to the foregoing proposal as the “Spin-off Proposal”;

Recommendation of the IAC Board of Directors

The IAC Board of Directors unanimously recommends that IAC stockholders vote:

In connection with the approval of the Spin-off, the IAC board of directors unanimously (i) approved, declared advisable and resolved to recommend each of the proposed amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal and the Corporate Opportunities Proposal and (ii) directed that the proposed amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal and the Corporate Opportunities Proposal and the Adjournment Proposal be submitted for approval by holders of IAC capital stock.

For a discussion of the factors that the IAC board of directors considered in determining to recommend in favor of the Spin-off Proposal and the Corporate Opportunities Proposal, see the section of this proxy statement/consent solicitation statement/prospectus entitled “The Spin-off—Reasons for the Spin-off; Recommendation of the IAC Board of Directors.”

IAC Record Date; Stockholders Entitled to Vote

Holders of IAC common stock and IAC Class B common stock at the close of business on [·], 2021, the record date for the special meeting established by the IAC board of directors, are entitled to receive notice of, and to vote their shares at, the special meeting and any related adjournments or postponements. As of the close of business on the record date, there were [·] shares of IAC common stock and 5,789,499 shares of IAC Class B common stock outstanding and entitled to vote at the special meeting. 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.

Voting by Directors and Executive Officers of IAC

As of the close of business on [·], 2021, IAC’s directors, executive officers and their respective affiliates held [·] shares of IAC common stock and 5,789,499 shares of IAC Class B common stock. This represents approximately [·]% of the shares of IAC common stock outstanding and entitled to vote as of the record date for the special meeting when voting as a separate class; 100% of the outstanding shares of IAC Class B common stock entitled to vote as of the record date for the special meeting when voting as a separate class; and approximately [·]% of the shares (and approximately [·]% of the total voting power) of IAC capital stock outstanding and entitled to vote as of the record date for the special meeting, when voting together as a single class.

IAC currently expects that the IAC directors and executive officers will vote their shares of IAC common stock and IAC Class B common stock in favor of the proposals to be considered at the special meeting, although none of them is obligated to do so. For more information on the required vote for the proposals to be considered at the special meeting and the beneficial ownership of IAC capital stock, see the sections of this proxy statement/consent solicitation statement/prospectus entitled “Special Meeting—Required Vote” and “Security Ownership of Certain Beneficial Owners and Management—Security Ownership of IAC Capital Stock Prior to the Spin-off,” respectively.

Quorum; Abstentions and Broker Non-Votes

The presence at the special 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 IAC Class B common stock at the special meeting constitutes a quorum. Stockholders who participate in the special meeting online at [·] will be deemed to be in person attendees 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 special 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. When the holders of IAC Class B common stock vote as a separate class, the presence at the special meeting of holders of a majority of the total votes entitled to be cast by holders of IAC Class B common stock is required for a quorum to be met. Shares of IAC common stock and IAC Class B common stock represented by proxy will be treated as present at the special meeting for purposes of determining whether there is a quorum, without regard to whether the proxy is marked as casting a vote or abstaining. In the absence of a quorum, the chairperson of the special meeting or holders of a majority of the voting power of the shares of IAC capital stock represented at the special meeting will have the power to adjourn the special meeting until a quorum is present.

Abstentions 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 outstanding shares or the number of shares present at the special meeting 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. Accordingly, an abstention will have the same effect as a vote “AGAINST” each of the proposals submitted for consideration at the special meeting.

Shares represented by broker non-votes are not treated as shares present and able to be voted, and are not counted for purposes of determining a quorum. Accordingly, a broker non-vote will have the following effects with respect to the proposals submitted for consideration at the special meeting:

Required Vote

The votes required for each proposal are as follows:

How to Vote

IAC stockholders may vote using any of the following methods:

You may also participate in the special meeting online at [·] and vote your shares of IAC capital stock online at that time, even if you have previously submitted your vote.

Proposal No. 1: Spin-off Proposal

Overview

IAC has proposed to separate its Vimeo business from the remaining businesses of IAC through a series of transactions that will result in the pre-transaction stockholders of IAC directly owning shares in both IAC and SpinCo, and in SpinCo becoming a separate public company.

IAC will effect the Spin-off through amendments to the IAC certificate of incorporation that will:

The full text of the amendments described in the Spin-off Proposal is set forth in Annex A to this proxy statement/consent solicitation statement/prospectus. You are urged to read the full text of the amendments in their entirety because they will amend the legal document that governs IAC.

If IAC’s stockholders approve the Spin-off Proposal and IAC completes the Spin-off, and the Vimeo merger is completed, the holders of IAC capital stock outstanding immediately prior to the Spin-off would continue to own all of the outstanding shares of IAC capital stock, and will become the direct owners of approximately 88% of SpinCo, and the remaining approximately 12% of SpinCo’s capital stock will be owned by Vimeo’s existing third-party stockholders. If IAC’s stockholders approve the Spin-off Proposal and IAC completes the Spin-off but the Vimeo merger is not completed, holders of IAC capital stock outstanding immediately prior to the Spin-off would continue to own all of the outstanding shares of IAC capital stock, and will become the direct owners of all of the outstanding shares of SpinCo, but the existing third-party stockholders of Vimeo would initially remain stockholders of Vimeo, and SpinCo would own approximately 88% of Vimeo.

Even if IAC receives all required stockholder approvals with respect to the Spin-off Proposal, the IAC board of directors has reserved the right to abandon the Spin-off. In that case, the proposed amendments to the IAC certificate of incorporation will not become effective.

Approval of the Spin-off Proposal requires (i) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC common stock entitled to vote on such matter, voting as a separate class; (ii) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC Class B common stock entitled to vote on such matter, voting as a separate class; (iii) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC capital stock entitled to vote on such matter, voting together as a single class; and (iv) the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC common stock entitled to vote on the proposal, other than any shares of IAC common stock owned, directly or indirectly, by the members of the IAC

board of directors, any person that IAC has determined to be an “officer” of IAC within the meaning of Rule 16a-1(f) of the Exchange Act, and the immediate family members of any of the foregoing.

Recommendation

Based upon the factors described under “Background of the Spin-off” and “Reasons for the Spin-off; Recommendation of the IAC Board of Directors,” the IAC board of directors has unanimously (i) approved, declared advisable and resolved to recommend each of the proposed amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal and (ii) directed that the proposed amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal be submitted for approval by holders of IAC capital stock.

The IAC board of directors unanimously recommends that IAC stockholders vote “FOR” the Spin-off Proposal.

Proposal No. 2: Corporate Opportunities Proposal

Overview

In connection with the Spin-off, IAC is asking you to approve the Corporate Opportunities Proposal. The Corporate Opportunities Proposal contemplates amendments to the IAC certificate of incorporation pursuant to which, following the Spin-off, IAC would renounce any interest or expectancy in certain corporate opportunities, which generally would have the effect that no officer or director of IAC who is also an officer or director of SpinCo will be liable to IAC or its stockholders for breach of any fiduciary duty by reason of the fact that any such individual directs a corporate opportunity to SpinCo instead of IAC, or does not communicate information regarding a corporate opportunity to IAC that the officer or director has directed to SpinCo, and to implement other related changes to the corporate opportunity provisions of the certificate of incorporation.

The full text of the amendments described in the Corporate Opportunities Proposal is set forth in Annex B to this proxy statement/consent solicitation statement/prospectus. You are urged to read the full text of the amendments in their entirety because they will amend the legal document that governs IAC.

If IAC stockholders approve the Spin-off Proposal and the Corporate Opportunities Proposal and if IAC completes the Spin-off, the SpinCo certificate of incorporation will include a reciprocal corporate opportunities provision.

Even if IAC receives all required stockholder approvals with respect to the Corporate Opportunities Proposal, the IAC board of directors has reserved the right to abandon the Spin-off. In that case, the proposed amendments to the IAC certificate of incorporation will not become effective.

Approval of the Corporate Opportunities Proposal requires the affirmative vote of the holders of at least a majority of the aggregate voting power of all outstanding shares of IAC capital stock entitled to vote on such matter, voting together as a single class.

Recommendation

The IAC board of directors has determined that the amendments described in the Corporate Opportunities Proposal are a practical solution to a situation in which an officer or director of IAC also serves as an officer or director of SpinCo, in view of the fact that IAC has in the past made, and each of IAC and SpinCo may in the future make, significant acquisitions and investments. The IAC board of directors believes that persons who serve as officers or directors of each of IAC and SpinCo should not be inhibited in making decisions with respect to the allocation of potential new business opportunities because of possible risks of litigation or potential liability. In light of the foregoing, the IAC board of directors has determined that the Corporate Opportunities Proposal is in the best interests of IAC and its stockholders.

Accordingly, the IAC board of directors has unanimously (i) approved, declared advisable and resolved to recommend the proposed amendments to the IAC certificate of incorporation that are the subject of the Corporate

Opportunities Proposal and (ii) directed that the proposed amendments to the IAC certificate of incorporation that are the subject of the Corporate Opportunities Proposal be submitted to the holders of IAC capital stock for their approval.

The IAC board of directors unanimously recommends that IAC stockholders vote “FOR” the Corporate Opportunities Proposal.

Proposal No. 3: Adjournment Proposal

Overview

IAC stockholders are being asked to approve a proposal that will give IAC the authority to adjourn or postpone the special meeting if necessary or appropriate, including to solicit additional proxies in favor of the proposals described in this proxy statement/consent solicitation statement/prospectus if there are insufficient votes at the time of the special meeting to approve the proposals described in this proxy statement/ consent solicitation statement/prospectus or in the absence of a quorum. If this adjournment proposal is approved, the special meeting could be adjourned by the IAC board of directors to any date. In addition, the IAC board of directors could postpone the special meeting before it commences. If the special meeting is adjourned for the purpose of soliciting additional proxies, stockholders who have already submitted their proxies will be able to revoke them at any time before their use.

If you sign and return a proxy and do not indicate how you wish to vote on any proposal, or if you sign and return a proxy and you indicate that you wish to vote in favor of the Spin-off Proposal but do not indicate a choice on the Adjournment Proposal, your shares of IAC capital stock will be voted in favor of the Adjournment Proposal. IAC does not anticipate calling a vote on this proposal if the other proposals described in this proxy statement/consent solicitation statement/prospectus are approved by the requisite number of shares of IAC capital stock at the special meeting.

The Adjournment Proposal requires approval by the affirmative vote of a majority of the voting power of the shares present in person or represented by proxy and entitled to vote on the matter (provided that a quorum is present).

Recommendation

The vote on the Adjournment Proposal is a vote separate and apart from the vote on the other proposals. Accordingly, you may vote to approve any other proposal, and vote not to approve the Adjournment Proposal and vice versa.

The IAC board of directors recommends that IAC stockholders vote “FOR” the Adjournment Proposal.

​

THE SPIN-OFF

Structure of the Spin-off

Subject to the terms and conditions set forth in the separation agreement, IAC’s Vimeo business will be separated from the remaining businesses of IAC through a series of transactions (which we refer to as the “Spin-off”) that will result in the pre-transaction stockholders of IAC directly owning shares in both IAC and SpinCo, and in SpinCo becoming a separate public company.

The Spin-off is structured to include the following steps:

IAC currently indirectly owns approximately 88% of the total outstanding shares of Vimeo, with the remaining Vimeo shares held by third-parties. In connection with the Spin-off, Vimeo’s existing shareholders agreement requires IAC to cause the conversion of the Vimeo shares held by such non-IAC Vimeo stockholders into SpinCo common stock, which we refer to as the “Vimeo minority exchange.” The shareholders agreement also requires that the non-lAC Vimeo stockholders be compensated (in the form of additional SpinCo equity) for dilution resulting from the issuance of SpinCo options in respect of vested IAC employee option awards that are adjusted in the Spin-Off. Each such Vimeo shareholder will be compensated for their ratable portion of 50% of the intrinsic value of the SpinCo options so issued, measured at the time of the Spin-off (see the section of this proxy statement/consent solicitation statement/ prospectus entitled “The Vimeo Merger—Consideration to Vimeo Stockholders”), and see Annex I—Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements of Vimeo Holdings, Inc. — Note 4.

an independent Vimeo with beneficial stability and protection from disruption, including disruption due to activist investors or opportunistic takeover attempts.

At a regularly scheduled meeting of the IAC board of directors held on September 9, 2020, the members of the board and representatives of management discussed the recent performance of Vimeo, noting Vimeo’s sustained growth since the onset of the pandemic and improving financial performance, but also highlighting Vimeo’s likely need for additional equity investment in order to accelerate that growth trajectory. Mr. Diller, IAC’s Chairman and Senior Executive, a member of the IAC board of directors and a beneficial owner of all of the outstanding shares of IAC Class B common stock (along with members of his family, including Mr. von Furstenberg), reviewed with the members of the board the strategic alternatives for Vimeo that had been discussed at the July board meeting, including the benefits of separating Vimeo from the rest of IAC via a spin-off or similar transaction. Mr. Diller noted that given the long-term growth trajectory for the Vimeo business, the uncertainty and volatility in the equity markets, Vimeo’s need for capital to finance future growth and M&A, and the profile of Vimeo’s current management team, it was his view that the best capital structure for an independent Vimeo would be one that replicated IAC’s dual class structure, which would allow Vimeo to chart a sound strategic direction and make necessary investments, and would insulate Vimeo’s management team from short-term pressures. Following discussion, including with IAC’s legal counsel, the members of the board unanimously agreed that IAC should pursue further consideration of the potential spin-off transaction and directed management to take all necessary steps in furtherance thereof. The members of the board noted that the final terms of any transaction would be subject to a vote of the independent members of the IAC board of directors, following separate deliberation by those members of the board, and would be subject to a vote of the holders of IAC common stock, including a vote of the public holders of IAC common stock (other than management, members of the board, and Mr. Diller’s related family entities).

On November 5, 2020, Vimeo and IAC Group entered into an investment agreement with entities affiliated with Thrive Capital and an entity affiliated with GIC Private Limited, pursuant to which such third-party investors acquired from Vimeo an aggregate of 8,655,510 shares of Vimeo voting common stock for an aggregate purchase price of approximately $150 million. In connection with the investment, Vimeo, IAC Group and the third-party investors entered into an amendment to the existing shareholders agreement among Vimeo, IAC Group and Vimeo’s other shareholders. The amendment to the shareholders agreement generally required the investors to cooperate with any Spin-off, conditional on the Spin-off terms being consistent with a set of agreed separation principles (other than departures from such principles not materially adverse to the third-party investors).

At a regularly scheduled meeting of the IAC board of directors held on December 7, 2020, the members of the board and representatives of management discussed updated information regarding Vimeo’s performance and financial profile. Mr. Diller informed the other members of the board that the holders of the shares of IAC Class B common stock would support a spin-off of Vimeo on the basis that a public Vimeo would have a dual class capital structure replicating that of IAC. The members of the IAC board of directors received a presentation from representatives of Allen & Company, a long-time financial advisor to IAC and Old IAC, regarding a potential spin-off of Vimeo. The presentation reviewed the potential benefits and risks of the transaction to IAC and to an independent Vimeo, including the importance of an attractively valued Vimeo equity currency for raising capital to fund Vimeo’s growth and M&A; the increased transparency to investors resulting from an independent Vimeo, which would allow each of IAC and Vimeo to highlight and focus on their distinct customers, strategic opportunities, assets and growth profiles; the ability of each of IAC and Vimeo to adopt a capital structure tailored to its individual profile; the ability of IAC to focus on its other businesses; the ability to capitalize on strong investor demand for SaaS enterprise software companies; and the risk posed by a perceived lack of a long-term track record for Vimeo’s management team, which could be mitigated by investor engagement and initial involvement by a limited number of IAC directors or officers on the Vimeo board. The presentation also reviewed the financial profile of an independent Vimeo, which included a review of market data for other enterprise SaaS companies and a comparison of how Vimeo compares to those businesses. The presentation observed that Vimeo has a lower immediate growth profile than its notable peers, but a longer opportunity to grow at healthy rates and cited intangible attributes of Vimeo, such as the uniqueness of its asset, quality of its brand, and strong management. The presentation also reviewed factors that might impact Vimeo’s future trading value. The presentation then discussed considerations around a dual class common stock structure for an independent Vimeo, noting the expectation that a dual class capital structure at Vimeo would not have any meaningful adverse impact on trading or valuation of Vimeo’s low-vote common stock and expressing the view that a dual class capital structure at Vimeo would provide a number of

benefits, including protection from unwanted third party takeover attempts and allowing Vimeo management to maintain a long-term focus for the benefit of Vimeo stockholders. Given the nature of the separation transaction and as is customary for spin-offs and similar transactions that do not involve an exchange of shares for financial consideration, the IAC board did not request or receive a fairness opinion.

Following discussion, the members of the IAC board of directors unanimously approved the amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal and the Corporate Opportunities Proposal and recommended that IAC stockholders vote in favor of such proposals, which resolutions expressly provided that the amendments, and the Spin-off, may be abandoned by the IAC board of directors prior to the effectiveness of the amendments, that the Spin-off shall be conditioned on the approval of the holders of a majority of the outstanding shares of IAC common stock entitled to vote on the proposal, other than any shares of the IAC common stock owned, directly or indirectly (including beneficial ownership), by Mr. Diller, members of the board, any Section 16 officer, or any of their immediate family members, and that the consummation of the Spin-off remains subject to the final approval of the IAC board of directors, including board approval of the terms of all proposed agreements to be entered into in connection with the Spin-off. As previously discussed by the board, the IAC board would not contemplate granting such final approval unless the Spin-off has the support of a majority of the independent members of IAC’s board of directors.

On January 25, 2021, Vimeo and IAC Group entered into investment agreements with funds and accounts advised by T. Rowe Price Associates, Inc. and affiliates of Oberndorf Enterprises, LLC, pursuant to which such third-party investors acquired from Vimeo an aggregate of 8,999,788 shares of Vimeo voting common stock for an aggregate purchase price of approximately $300 million, and became parties to the Vimeo shareholders agreement.

Reasons for the Spin-off; Recommendation of the IAC Board of Directors

The IAC board of directors, with the assistance of management and the company’s legal and financial advisors, regularly reviews IAC’s strategic, operational and financial direction, including with respect to potential spin-offs or divestitures of IAC’s various business operations. After careful consideration, and taking into account the belief of the IAC board of directors that the pursuit of the Spin-off is in the best interests of IAC and its stockholders, the IAC board of directors has unanimously (i) declared advisable each of the proposed amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal and the Corporate Opportunities Proposal and resolved to recommend the approval of the Spin- off Proposal and the Corporate Opportunities Proposal to the holders of IAC capital stock and (ii) directed that the proposed amendments to the IAC certificate of incorporation that are the subject of the Spin-off Proposal and the Corporate Opportunities Proposal be submitted to the holders of IAC capital stock for their approval.

In the course of reaching its recommendation, the IAC board of directors considered a wide variety of factors relating to the Spin-off. Among other things, the IAC board of directors considered the following potential benefits of the Spin-off:

However, IAC cannot assure you that, following the consummation of the Spin-off, any of the benefits described above or any other benefits will be realized to the extent anticipated, or at all. In the course of reaching its recommendation, the IAC board of directors also considered certain risks and potentially negative factors relating to the Spin-off, including:

The IAC board of directors concluded that the potential benefits of the Spin-off outweighed these negative factors.

In connection with its consideration of the Spin-off, the IAC board of directors considered the fact that Mr. Diller, the beneficial owner of all of the outstanding shares of IAC Class B common stock, had stated that he would not be supportive, in his capacity as a stockholder, of the Spin-off unless an independent Vimeo were structured with dual-class common stock and the Spin-Off were structured in a way that would result in Mr. Diller’s becoming the beneficial owner of SpinCo Class B Common Stock with substantially similar voting and other rights as his current rights at IAC. See the sections of this proxy statement/consent solicitation statement/prospectus entitled “Risk Factors—Risks Relating to IAC’s Business Following the Spin-off—Mr. Diller and certain members of his family will be able to exercise significant influence over the composition of IAC’s Board of Directors, matters subject to stockholder approval and IAC’s operations” and “Security Ownership of Certain Beneficial Owners and Management” for a description of Mr. Diller’s (and Mr. von Furstenberg’s) beneficial ownership of IAC securities. The IAC board of directors considered the potential means of structuring the Spin-off under IAC’s existing certificate of incorporation, including the fact that a Spin-off structured as a reclassification could not be accomplished without the affirmative vote of the majority of the holders of the shares of IAC Class B common stock, and that dividing IAC and Vimeo into two separate companies with the same type of dual- class structure did not provide Mr. Diller or the related holders of the shares of IAC Class B common stock additional rights or benefits relative to their existing rights over the combined IAC and Vimeo assets. The IAC board of directors also considered the potential impact of a dual-class structure on an independent Vimeo, including:

This discussion of the information and factors considered by the IAC board of directors in reaching its conclusions and recommendation includes the principal factors considered by the IAC board of directors, but is not intended to be exhaustive and may not include all of the factors considered by the IAC board of directors. In view of the wide variety of factors considered in connection with its evaluation of the Spin- off, and the complexity of these matters, the IAC board of directors did not find it useful and did not attempt to quantify, rank or assign any relative or specific weights to the various factors that it considered in reaching its determination to make its recommendation to IAC stockholders. Rather, the IAC board of directors viewed its decisions as being based on the totality of the information presented to it and the factors it considered. In addition, individual members of the IAC board of directors may have given differing weights to different factors.

The factors, potential risks and uncertainties contained in this explanation of the IAC board of directors’ reasons and other information presented in this section contain information that is forward- looking in nature and, therefore, should be read in light of the factors discussed in “Cautionary Note Regarding Forward-Looking Statements.”

Regulatory Requirements Related to the Spin-off

The parties are not aware of any material governmental approvals or actions that are necessary for the completion of the Spin-off. However, certain IAC and SpinCo stockholders may have filing obligations under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and should consult their own legal advisors.

Treatment of IAC Equity Awards

IAC Options

Each option to purchase shares of IAC common stock will convert into an option to purchase shares of IAC common stock and an option to purchase shares of SpinCo common stock with adjustments to the number of shares subject to each option and the option exercise prices based on (1) the value of IAC common stock prior to the Spin-off and (2) the value of IAC common stock and the value of SpinCo common stock after giving effect to the Spin-off.

Except as otherwise described above and except to the extent otherwise provided under local law, following the Spin-off, the converted options generally will have the same terms and conditions, including the same exercise periods, as the options to purchase shares of IAC common stock had immediately prior to the Spin-off.

Following the Spin-off, solely for purposes of determining the expiration of options with respect to shares of common stock of one company held by employees of the other company, IAC and SpinCo employees will be deemed employed by both companies for so long as they continue to be employed by whichever of the companies employs them immediately following the Spin-off.

IAC RSUs

All IAC restricted stock units (“RSUs”) will continue to be IAC RSUs following the Spin-off, with adjustments to the number of RSUs based on (1) the value of IAC common stock prior to the Spin-off and (2) the value of IAC common stock after giving effect to the Spin-off.

IAC RSUs granted in respect of service as an IAC director will convert into adjusted IAC RSUs with adjustments to the number of IAC RSUs based on (1) the value of IAC common stock prior to the Spin-off and (2) the value of IAC common stock after giving effect to the Spin-off.

Except as otherwise described above and except to the extent otherwise provided under local law, following the Spin-off, the RSUs of the applicable company generally will have the same terms and conditions, including the same vesting provisions, as the IAC RSUs had immediately prior to the date of the Spin-off.

Treatment of Mr. Levin’s IAC Restricted Stock Award

On November 5, 2020, Mr. Levin received an IAC Restricted Stock award covering 3,000,000 shares of IAC common stock. For a description of this award, see “IAC Executive Officer and Director Compensation—Executive Compensation—Grants of IAC Plan-Based Awards in 2020.”

In the Spin-off, Mr. Levin will receive in respect of each share of IAC restricted common stock that he holds a number of shares of SpinCo common stock based on the Spin-off exchange ratio and will retain his 3,000,000 shares of IAC restricted common stock.

In connection with the Spin-off:

For purposes of the SpinCo Restricted Stock award the definition of “Change in Control” will mirror the definition that applies to the IAC Restricted Stock award, except that the relevant entity for purposes of the definition will be SpinCo, rather than IAC. Upon a Change in Control of SpinCo, a designated percentage of the SpinCo Restricted Stock award will vest based on the timing of the Change of Control and subject to a floor of 30%, escalating to 100%. Except as otherwise noted above, the SpinCo Restricted Stock award generally will have the same terms as the IAC Restricted Stock award.

Treatment of Vimeo Equity Awards

Vimeo has outstanding stock appreciation rights (“Vimeo SARs”) the value of which corresponds to shares of Vimeo common stock. Upon exercise, the Vimeo SARs generally settle for shares of IAC common stock representing the increase in value between the Vimeo SAR grant date and the date a holder exercises the Vimeo SAR.

In the Vimeo merger, each Vimeo SAR will convert into a stock appreciation right corresponding to, and settled in, shares of SpinCo common stock (“SpinCo SAR”), with adjustments to the number of shares subject to each SpinCo SAR and the base price applicable to each SpinCo SAR, based on the exchange ratio in the Vimeo merger. The SpinCo SARs otherwise will have terms and conditions that are customary for a public company stock appreciation right.

Interests of Certain Persons in the Spin-off

In considering the recommendation of IAC’s Board of Directors to vote in favor of the Spin-off, stockholders of IAC should be aware that directors and executive officers of IAC have interests in the Spin- off that may be in addition to or different from the interests of stockholders generally. The IAC Board of Directors was aware of these interests and considered them, among other factors, in approving the Spin-off.

Certain of IAC’s directors and executive officers currently own shares of IAC common stock and/or equity awards that are denominated in shares of IAC common stock. In the Spin-off, these directors and executive officers will receive reclassified shares of IAC common stock (including restricted shares in the case of Mr. Levin), shares of Vimeo common stock (including restricted shares in the case of Mr. Levin), adjusted options to purchase shares of IAC common stock, options to purchase shares of Vimeo common stock and adjusted IAC restricted stock units in respect of the IAC securities that they currently own. See “—Treatment of IAC Equity Awards.”

No Dissenters’ Rights for Holders of IAC Capital Stock

Under the DGCL, holders of shares of IAC capital stock will not have appraisal or dissenters’ rights in connection with the Spin-off.

Accounting Treatment

IAC and Vimeo prepare their financial statements in accordance with United States generally accepted accounting principles. The Spin-off will be accounted for by IAC as a discontinuance of the consolidated businesses comprising SpinCo after the Spin-off. For accounting purposes, the measurement date for discontinued operations will be on the date of the Spin-off. After the Spin-off, the assets and liabilities of SpinCo will be accounted for at their historical carrying values immediately prior to the Spin-off.

Listing of IAC Common Stock and SpinCo Common Stock

IAC common stock currently trades on Nasdaq under the ticker symbol “IAC” and IAC expects that it will continue to do so after the Spin-off.

SpinCo will apply to list SpinCo common stock on [·] and has reserved the ticker symbol “[·]” for such listing. Trading in SpinCo common stock under this symbol is expected to begin on the first business day following the date that IAC completes the Spin-off. However, there can be no assurance that a viable and active trading market will develop.

Post-Spin-off Governance and Management

IAC

There will be no changes to the IAC board of directors or senior management team, or to IAC’s bylaws, in connection with the Spin-off.

As of the completion of the Spin-off, the current IAC certificate of incorporation will be amended pursuant to the forms of amendment set forth in Annex A to this proxy statement/consent solicitation statement/prospectus and, if the Corporate Opportunities Proposal is approved, Annex B to this proxy statement/consent solicitation statement/prospectus, and will be restated to be in the form filed as Exhibit 3.5 to the registration statement of which this proxy statement/consent solicitation statement/prospectus forms a part;

For more information regarding IAC’s governance and management, see the section of this proxy statement/consent solicitation statement/prospectus entitled “IAC Directors and Executive Officers.”

SpinCo

We are in the process of identifying the persons who are expected to serve on the SpinCo board of directors following the completion of the Spin-off and will include information concerning those persons in an amendment to this proxy statement/consent solicitation statement/prospectus.

In connection with their prior investment in Vimeo (see the section of this proxy statement/consent solicitation statement/prospectus entitled “Recent Developments—Minority Investments in Vimeo.”), Vimeo and IAC agreed that if Thrive continues to own at least 75% of the shares of Vimeo voting common stock acquired by Thrive pursuant to the Investment Agreement, and Thrive owns at least 2% of the outstanding common stock of Vimeo at the time of the Spin-off, Thrive will have the right to recommend a candidate for consideration for appointment to the initial post-Spin-off SpinCo board of directors, and Vimeo and IAC will consider such candidate in good faith.

The executive officers of Vimeo prior to the Spin-off will be appointed to serve as the executive officers of SpinCo following the Spin-off. Anjali Sud, Narayan Menon, Mark Kornfilt and Michael A. Cheah are currently expected to serve as executive officers of SpinCo following the Spin-off. At this time, there are no other individuals identified to serve as executive officers of SpinCo following the Spin-off.

SpinCo’s current certificate of incorporation and bylaws will be amended and restated to be in the forms filed as Exhibits 3.9 and 3.10, respectively, to the registration statement of which this proxy statement/ consent solicitation statement/prospectus forms a part.

For more information regarding SpinCo’s post-Spin-off governance and management, see the section of this proxy statement/consent solicitation statement/prospectus entitled “SpinCo Directors and Executive Officers.”

Shareholder Litigation Relating to the Spin-Off

On January 22, 2021, a putative class action complaint challenging the Spin-off was filed in the Supreme Court of the State of New York, New York County. The complaint is captioned Drulias v Levin et al., index number 650504/2021, and names as defendants each member of IAC’s board of directors and IAC. The complaint asserts claims for breach of fiduciary duty under Delaware law and, among other things, alleges that defendants breached their fiduciary duties by making materially inadequate disclosures and material omissions in this proxy statement/consent solicitation statement/prospectus. In addition to costs and attorneys’ fees, the complaint seeks a declaration that defendants have breached their fiduciary duties, to require the defendants to cause IAC to make corrective disclosures, and an award of compensatory and/or rescissory damages. IAC believes the claims are without merit.
