FORWARD-LOOKING STATEMENTS

          This prospectus supplement and the accompanying prospectus and the documents incorporated by reference herein or therein may contain certain "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995. The use of words such as "anticipates," "estimates," "expects," "plans" and "believes," among others, generally identify forward-looking statements. These forward-looking statements include, among others, statements relating to our future financial performance, business prospects and strategy, anticipated trends and prospects in home services industry, expected synergies and other benefits to be realized following the combination of the HomeAdvisor Business (as defined below) and Angie's List, Inc. on September 29, 2017 (the "Combination") and other similar matters. "HomeAdvisor Business" means the businesses and operations of the HomeAdvisor segment of IAC/InterActiveCorp ("IAC"), our controlling stockholder, as reported in IAC's filings with the SEC.

          These forward-looking statements are based on our management's current expectations and assumptions about future events as of the date of this prospectus supplement, which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict. Actual results could differ materially from those contained in these forward-looking statements for a variety of reasons, including, among others: (i) our ability to compete effectively against current and future competitors, (ii) the failure or delay of the home services market to migrate online, (iii) adverse economic events or trends, particularly those that adversely impact consumer confidence and spending behavior, (iv) our ability to establish and maintain relationships with quality service professionals, (v) our ability to build, maintain and/or enhance our various brands, (vi) our ability to market our various products and services in a successful and cost-effective manner, (vii) our continued ability to communicate with consumers and service professionals via e-mail or an effective alternative means of communication, (viii) our ability to introduce new and enhanced products and services that resonate with consumers and service professionals and that we are able to effectively monetize, (ix) our ability to realize the expected benefits of the Combination within the anticipated time frames or at all, (x) the integrity, efficiency and scalability of our technology systems and infrastructures (and those of third parties) and our ability to enhance, expand and adapt our technology systems and infrastructures in a timely and cost-effective manner, (xi) our ability to protect our information technology systems and infrastructures from cyberattacks (and those of third parties) and to protect personal and confidential user information, (xii) the occurrence of data security breaches, fraud and/or additional regulation involving or impacting credit card payments, (xiii) our ability to adequately protect our intellectual property rights and not infringe the intellectual property rights of third parties, (xiv) our ability to operate (and expand into) international markets successfully, (xv) operational and financial risks relating to acquisitions, (xvi) changes in key personnel, (xvii) increased costs and strain on our management as a result of operating as a new public company, (xviii) adverse litigation outcomes and (xix) various risks related to our relationship with IAC and our outstanding indebtedness. Certain of these and other risks and uncertainties are discussed on page S-4 of this prospectus supplement and in our filings with the SEC, including in Part I — Item 1A — Risk Factors of our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

          Other unknown or unpredictable factors that could also adversely affect our business, financial condition and operating results may arise from time to time. In light of these risks and uncertainties, the forward-looking statements discussed in this prospectus supplement and the accompanying prospectus may not prove to be accurate. Accordingly, you should not place undue reliance on these forward-looking statements, which only reflect the views of our management as of the date of this prospectus supplement. We do not undertake to update these forward-looking statements.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

          The following is a summary of certain U.S. federal income tax considerations generally applicable to the ownership and disposition of our Class A Common Stock acquired in this offering by a Non-U.S. Holder (as defined below) as of the date hereof. This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, which we refer to as the "Code," applicable U.S. Treasury regulations, judicial opinions, and administrative rulings and published positions of the Internal Revenue Service ("IRS"), each as in effect as of the date hereof. These authorities are subject to change or different interpretations, possibly on a retroactive basis, and any such change or different interpretation could affect the accuracy of the statements and conclusions set forth in this summary.

          For purposes of this summary, a "Non-U.S. Holder" means a beneficial owner of our Class A Common Stock that is, for U.S. federal income tax purposes, neither a partnership nor any of the following:

•

an individual who is a citizen or resident of the United States;



•

a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia;



•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or



•

a trust if it (1) is subject to the primary supervision of a court within the United States and the control of one or more U.S. persons with respect to all of its substantial decisions or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

          If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our Class A Common Stock, the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. Partnerships and partners in a partnership considering an investment in our Class A Common Stock should consult their tax advisors about the U.S. federal income tax considerations applicable to them in their particular circumstances.

          This summary does not address all aspects of U.S. federal income taxation that may be relevant to particular Non-U.S. Holders in light of their individual circumstances, including Non-U.S. Holders that are subject to special rules, such as, U.S. expatriates, banks or other financial institutions, insurance companies, brokers or dealers in securities or currencies, traders that elect to mark-to-market their securities, controlled foreign corporations, passive foreign investment companies, Non-U.S. Holders subject to the alternative minimum tax, or Non-U.S. Holders who hold shares of our Class A Common Stock as part of a straddle, hedge, conversion transaction or other integrated investment. Non-U.S. Holders should consult their tax advisors to determine the U.S. federal, state, local and non-U.S. tax considerations applicable to the ownership and disposition of our Class A Common Stock that may be relevant to them.

          This summary does not discuss any U.S. federal tax consequences other than income tax consequences (e.g., estate or gift tax), any state, local, or non-U.S. tax considerations or the Medicare tax imposed on certain net investment income. In addition, this summary applies only to Non-U.S. Holders that hold our Class A Common Stock as a capital asset within the meaning of the Code (generally, property held for investment purposes).

          EACH NON-U.S. HOLDER SHOULD CONSULT ITS TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, LOCAL, AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES OF OWNING AND DISPOSING OF OUR CLASS A COMMON STOCK.

Table of Contents

Distributions on Our Class A Common Stock

          Distributions with respect to our Class A Common Stock will be treated as dividend income to the extent such distributions are paid from our current or accumulated earnings and profits as determined for U.S. federal income tax purposes. If a distribution exceeds our current and accumulated earnings and profits, the excess will generally be treated first as a return of capital to the extent of the Non-U.S. Holder's adjusted tax basis in our Class A Common Stock (and will reduce the Non-U.S. Holder's basis in such Class A Common Stock, determined on a share by share basis (but not below zero)) and thereafter as capital gain from the sale or exchange of such Class A Common Stock, subject to the tax treatment described below in "— Sale, Exchange, or Other Taxable Disposition of Common Stock." Generally, the gross amount of dividends paid to Non-U.S. Holders will be subject to withholding of U.S. federal income tax at a rate of 30% or at a lower rate if an applicable income tax treaty so provides and the applicable withholding agent has received proper certification as to the application of that treaty.

          Unless an applicable income tax treaty provides otherwise, dividends that are "effectively connected" with a Non-U.S. Holder's conduct of a trade or business within the United States are generally subject to U.S. federal income tax on a net basis at regular graduated rates, in the same manner as if the Non-U.S. Holder were a United States person (as defined in the Code), and are exempt from the 30% withholding tax described above, provided that certain certification requirements are satisfied. A Non-U.S. Holder that is a corporation may also, under certain circumstances, be subject to a "branch profits tax" at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty on its effectively connected earnings and profits, subject to adjustments.

          To claim the benefits of an applicable income tax treaty or an exemption from withholding because the income is effectively connected with the conduct of a trade or business in the United States, a Non-U.S. Holder will generally be required to provide a properly executed Internal Revenue Service ("IRS") Form W-8BEN or W-8BEN-E (if the holder is claiming the benefits of an income tax treaty) or IRS Form W-8ECI (for income effectively connected with the conduct of a trade or business in the United States) or other suitable form. A Non-U.S. Holder eligible for a reduced rate of withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the specific manner of claiming the benefits of the treaty.

Sale, Exchange, or Other Taxable Disposition of Class A Common Stock

          A Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax with respect to gain recognized on the sale, exchange, or other taxable disposition of our Class A Common Stock, unless:

•

in the case of a Non-U.S. Holder that is a non-resident alien individual, such Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale, exchange, or other taxable disposition, and certain other conditions are met;



•

the gain is "effectively connected" with such Non-U.S. Holder's conduct of a trade or business within the United States; or



•

we are or have been a "United States real property holding corporation" for U.S. federal income tax purposes at any time within the shorter of the five-year period ending on the date of such sale, exchange, or other taxable disposition or the period that such Non-U.S. Holder held such Class A Common Stock and either (a) our Class A Common Stock was not treated as regularly traded on an established securities market during a relevant period

S-9

---

Table of Contents

in the calendar year in which the sale, exchange, or other taxable disposition occurs, or (b) such Non-U.S. Holder owns or owned (actually or constructively) more than 5% of our Class A Common Stock at any time during the shorter of the two periods described above.

          Although there can be no assurance, we do not believe that we are, or have been, and we do not anticipate becoming, a "United States real property holding corporation" for U.S. federal income tax purposes. If any gain recognized on a sale, exchange, or other taxable disposition of our Class A Common Stock is effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States, such Non-U.S. Holder will generally be subject to U.S. federal income tax on the net gain from the disposition of our Class A Common Stock at regular graduated rates in the same manner as if such Non-U.S. Holder were a United States person as defined in the Code unless an applicable income tax treaty provides otherwise. A Non-U.S. Holder that is a foreign corporation, may also be subject to a branch profits tax at a rate of 30% (or a lower applicable treaty rate) on its effectively connected earnings and profits, subject to adjustments. If a Non-U.S. Holder is an individual that is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met, the Non-U.S. Holder will generally be subject to U.S. federal income tax at a rate of 30% (unless otherwise provided by an applicable treaty) on any capital gain recognized on the disposition of our Class A Common Stock, which may be offset by certain U.S.-source capital losses.

Foreign Account Tax Compliance Act

          Withholding at a rate of 30% will generally be required in certain circumstances on dividends in respect of, and, after December 31, 2018, gross proceeds from the sale or other disposition of, shares of our Class A Common Stock held by certain foreign financial institutions (whether such foreign financial institution is the beneficial owner or an intermediary and including investment funds), unless such institution (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities or (iii) qualifies for an exemption. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which our Class A Common Stock is held will affect the determination of whether such withholding is required. Similarly, dividends in respect of, and, after December 31, 2018, gross proceeds from the sale or other disposition of, our Class A Common Stock held by a non-financial non-U.S. entity (whether such entity is the beneficial owner or an intermediary) that does not qualify under certain exceptions generally will be subject to withholding at a rate of 30%, unless such entity either (x) certifies to the applicable withholding agent that such entity does not have any "substantial United States owners" or (y) provides certain information regarding the entity's "substantial United States owners," which information the applicable withholding agent will be required in turn to provide to the U.S. Department of Treasury. Prospective investors should consult their tax advisors regarding the possible implications of these rules on their investment in our Class A Common Stock.

UNDERWRITING

          The Company, the selling stockholders and the underwriter named below (the "underwriter") have entered into an underwriting agreement with respect to the Class A Common Stock (the "shares") being offered. Subject to certain conditions, the underwriter has agreed to purchase from the selling stockholders, and the selling stockholders have agreed to sell to the underwriter, the number of shares listed next to its name indicated in the following table.

          The underwriter is committed to take and pay for all of the shares being offered, if any are taken.

          The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriter by the selling stockholders.

          Shares sold by the underwriter to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus. Any shares sold by the underwriter to securities dealers may be sold at a discount of up to $0.175 per share from the initial public offering price. After the initial offering of the shares, the underwriter may change the offering price and the other selling terms. The offering of the shares by the underwriter is subject to receipt and acceptance and subject to the underwriter's right to reject any order in whole or in part.

          The Company estimates that the total expenses of the offering payable by the Company, excluding underwriting discounts and commissions, which will be paid by the selling stockholders, will be approximately $450,000.

          The Company and the selling stockholders have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933.

          In connection with the offering, the underwriter may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriter of a greater number of shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriter in the open market prior to the completion of the offering.

          Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriter for its own accounts, may have the effect of preventing or retarding a decline in the market price of the Company's stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. The underwriter is not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on NYSE, NASDAQ NMS or relevant exchange, in the over-the-counter market or otherwise.

          The Company may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with

Table of Contents

those derivatives, the third parties may sell securities covered by this prospectus, including in short sale transactions. If so, the third party may use securities pledged by the Company or borrowed from the Company or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from the Company in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter or will be identified in a post-effective amendment.

          The underwriter and its affiliates are a full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. The underwriter and its affiliates have provided, and may in the future provide, a variety of these services to the Company and to persons and entities with relationships with the Company, for which they received or will receive customary fees and expenses.

          In the ordinary course of their various business activities, the underwriter and its affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the Company (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with the Company. The underwriter and its affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus, any accompanying prospectus supplement(s) and the documents incorporated by reference herein or therein may contain certain "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995. The use of words such as "anticipates," "estimates," "expects," "plans" and "believes," among others, generally identify forward-looking statements. These forward-looking statements include, among others, statements relating to our future financial performance, business prospects and strategy, anticipated trends and prospects in home services industry, expected synergies and other benefits to be realized following the combination of the HomeAdvisor Business (as defined below) and Angie's List, Inc. on September 29, 2017 (the "Combination") and other similar matters. "HomeAdvisor Business" means the businesses and operations of the HomeAdvisor segment of IAC/InterActiveCorp ("IAC"), our controlling stockholder, as reported in IAC's filings with the SEC.

        These forward-looking statements are based on our management's current expectations and assumptions about future events, which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict. Actual results could differ materially from those contained in these forward-looking statements for a variety of reasons, including, among others: (i) our ability to compete effectively against current and future competitors, (ii) the failure or delay of the home services market to migrate online, (iii) adverse economic events or trends, particularly those that adversely impact consumer confidence and spending behavior, (iv) our ability to establish and maintain relationships with quality service professionals, (v) our ability to build, maintain and/or enhance our various brands, (vi) our ability to market our various products and services in a successful and cost-effective manner, (vii) our continued ability to communicate with consumers and service professionals via e-mail or an effective alternative means of communication, (viii) our ability to introduce new and enhanced products and services that resonate with consumers and service professionals and that we are able to effectively monetize, (ix) our ability to realize the expected benefits of the Combination within the anticipated time frames or at all, (x) the integrity, efficiency and scalability of our technology systems and infrastructures (and those of third parties) and our ability to enhance, expand and adapt our technology systems and infrastructures in a timely and cost-effective manner, (xi) our ability to protect our systems from cyberattacks and to protect personal and confidential user information, (xii) the occurrence of data security breaches, fraud and/or additional regulation involving or impacting credit card payments, (xiii) our ability to adequately protect our intellectual property rights and not infringe the intellectual property rights of third parties, (xiv) our ability to operate (and expand into) international markets successfully, (xv) operational and financial risks relating to acquisitions, (xvi) changes in key personnel, (xvii) increased costs and strain on our management as a result of operating as a new public company, (xviii) adverse litigation outcomes and (xix) various risks related to our relationship with IAC and our outstanding indebtedness. Certain of these and other risks and uncertainties are discussed on page 4 of this prospectus and in our filings with the SEC, including in Part I-Item 1A-Risk Factors of our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (our "2017 Form 10-K").

        Other unknown or unpredictable factors that could also adversely affect our business, financial condition and operating results may arise from time to time. In light of these risks and uncertainties, the forward-looking statements discussed in this prospectus may not prove to be accurate. Accordingly, you should not place undue reliance on these forward-looking statements, which only reflect the views of our management as of the date of this prospectus. We do not undertake to update these forward-looking statements.

        In connection with the consummation of our acquisition of Handy Technologies, Inc. ("Handy") on October 19, 2018 (the "Acquisition") pursuant to the terms of an acquisition agreement dated September 29, 2018, we issued an aggregate of 7,482,167 shares of our Class A Common Stock to the selling stockholders. The selling stockholders were equity holders in Handy and received shares of Class A Common Stock as consideration in the Acquisition in reliance on the private offering exemption of Section 4(a)(2) of the Securities Act. Concurrently with the closing of the Acquisition, we also entered into the registration rights agreement with the selling stockholders (the "Registration Rights Agreement"), whereby we agreed to file with the SEC a registration statement on Form S-3 in accordance with Rule 415 under the Securities Act to register the shares of our Class A Common Stock that we issued to the selling stockholders pursuant to the Acquisition.

        The registration statement of which this prospectus forms a part covers the public resale of the shares of Class A Common Stock beneficially owned by the selling stockholders listed in the table below. The selling stockholders may from time to time offer and sell, pursuant to this prospectus and in accordance with the Registration Rights Agreement, any or all of the shares of Class A Common Stock beneficially owned by them and covered by this prospectus. The selling stockholders may sell some, all or none of the shares of Class A Common Stock covered by this prospectus and make no representations that such shares will be offered for sale.

        As used in this prospectus, the term "selling stockholders" includes only the selling stockholders listed below, and the pledgees, donees, transferees, assignees, successors and others who later come to hold any of the selling stockholders' interest in our Class A Common Stock other than through a public sale. Information about the selling stockholders and certain transferees may change over time. Any changed information will be set forth in prospectus supplements, if required. The selling stockholders may sell all, some or none of their shares in this offering. See "Plan of Distribution."

        The table below presents information regarding the selling stockholders and the shares of Class A Common Stock that they may offer and sell pursuant to this prospectus. Beneficial ownership is determined in accordance with applicable SEC rules, which generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to such securities.

DESCRIPTION OF CAPITAL STOCK

        This prospectus contains a summary description of our capital stock and certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws. This summary description is not complete and is qualified in its entirety by: (i) the full text of our amended and restated certificate of incorporation and amended and restated bylaws, which are incorporated by reference herein as exhibits to our registration statement of which this prospectus forms a part, and (ii) the applicable provisions of Delaware law.

        Our authorized capital stock consists of 5,500,000,000 shares of stock, comprised of 2,000,000,000 shares of Class A Common Stock, par value $0.001 per share, 1,500,000,000 shares of Class B Common Stock, par value $0.001 per share ("Class B Common Stock"), 1,500,000,000 shares of Class C Common Stock, par value $0.001 per share ("Class C Common Stock"), and 500,000,000 shares of preferred stock, par value $0.001 per share. As of September 30, 2018, there were 66,073,192 shares of Class A Common Stock outstanding, 415,904,443 shares of Class B Common Stock outstanding and no shares of Class C Common Stock or preferred stock outstanding. The number of authorized shares of any class of stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the vote of the holders of a majority of the voting power of all then-outstanding shares of Class A Common Stock, Class B Common Stock and any outstanding series of preferred stock entitled to vote thereon, voting together as one class.

Common Stock

        The rights of holders of Class A Common Stock, Class B Common Stock and Class C Common Stock are identical, except for the differences described below under "—Voting Rights," "—Dividend Rights" and "—Conversion Rights." Any authorized but unissued shares of Class A Common Stock, Class B Common Stock and Class C Common Stock are available for issuance by our board of directors without any further stockholder action, subject to any limitations imposed by the Marketplace Rules of The Nasdaq Stock Market, LLC (the "Nasdaq Rules").

Voting Rights

        Holders of Class A Common Stock are entitled to one vote per share on all matters to be voted upon by stockholders. Holders of Class B Common Stock are entitled to ten votes per share on all matters to be voted upon by stockholders. Holders of Class C Common Stock are not entitled to any votes per share (except as, and then only to the extent, otherwise required by the laws of Delaware, in which case holders of Class C Common Stock are entitled to one one-hundredth of a vote per share). None of the holders of Class A Common Stock, Class B Common Stock or Class C Common Stock have cumulative voting rights in the election of directors.

Dividend Rights

        Holders of Class A Common Stock, Class B Common Stock and Class C Common Stock are entitled to ratably receive dividends (other than in the event of a share distribution or an asset distribution, as further described below) if, as and when declared from time to time by our board of directors in its discretion out of funds legally available for that purpose, after payment of any dividends required to be paid on any outstanding preferred stock. Under Delaware law, we can only pay dividends either out of "surplus" or out of the current or the immediately preceding year's net profits. Surplus is defined as the excess, if any, at any given time, of the total assets of a corporation over its total liabilities and statutory capital. The value of a corporation's assets can be measured in a number of ways and may not necessarily equal their book value.

        In a distribution of shares of our common stock, we may distribute: (i) shares of Class C Common Stock (or securities convertible into or exercisable or exchangeable for shares of Class C Common Stock), on an equal per share basis, to holders of Class A Common Stock, Class B Common Stock and Class C Common Stock or (ii) (x) shares of Class A Common Stock (or securities convertible into or exercisable or exchangeable for shares of Class A Common Stock), on an equal per share basis, to holders of Class A Common Stock, (y) shares of Class B Common Stock (or securities convertible into or exercisable or exchangeable for shares of Class B Common Stock), on an equal per share basis, to holders of Class B Common Stock and (z) shares of Class C Common Stock (or securities convertible into or exercisable or exchangeable for shares of Class C Common Stock), on an equal per share basis, to holders of Class C Common Stock.

        In a distribution of any other of our securities or the capital stock or other securities of another person or entity, we may choose to distribute: (i) identical securities, on an equal per share basis, to holders of Class A Common Stock, Class B Common Stock and Class C Common Stock, (ii) a separate class or series of securities to holders of shares of Class A Common Stock, a separate class of securities to holders of shares of Class B Common Stock and a separate class or series of securities to holders of shares of Class C Common Stock, on an equal per share basis, (iii) a separate class or series of securities to holders of shares of Class B Common Stock and a different class or series of securities to holders of shares of Class A Common Stock and Class C Common Stock, on an equal per share basis or (iv) a separate class or series of securities to holders of shares of Class C Common Stock and a different class or series of securities to holders of shares of Class A Common Stock and Class B Common Stock, on an equal per share basis, provided that, in the case of clause (ii), (iii) or (iv), the different classes or series of securities to be distributed are not different in any respect other than their relative voting rights (and any related differences in designation, conversion, redemption and share distribution provisions, as applicable), with either (x) holders of shares of Class B Common Stock receiving the class or series of securities having the highest relative voting rights or (y) holders of shares of Class B Common Stock and Class A Common Stock receiving a class or series of securities having the highest relative voting rights. A dividend involving a class or series of securities of another person or entity may be treated as a share distribution or as an asset distribution as determined by our board of directors.

        In a distribution of our assets (including shares of any class or series of capital stock of another person or entity owned by us) to holders of any class or classes of common stock, a dividend in cash and/or other property will be paid to holders of each other class of common stock then outstanding on an equal per share basis in an amount, in the case of a dividend consisting solely of cash, equal to the fair market value of such holders' ownership interest in the assets paid as a dividend pursuant to the asset distribution, or having a fair market value, in the case of any other dividend, equal to the fair market value of such holders' ownership interest in assets paid as a dividend pursuant to the asset distribution.

        Our board of directors has the power and authority to, in good faith, make all determinations regarding, among other things: (i) whether or not a dividend is an equal dividend per share or is declared and paid on an equal per share basis, (ii) whether one or more classes or series of securities differ in any respect other than their relative voting rights and (iii) any other interpretations that may be required under the dividend rights provisions of the amended and restated certificate of incorporation described above.

Conversion Rights

        Shares of Class B Common Stock are convertible into shares of Class A Common Stock at the option of the holder at any time on a share for share basis. The conversion ratio will in all events be equitably preserved in the event of any recapitalization of the Company by means of a stock dividend on, or a stock split or combination of, the outstanding shares of Class A Common Stock or of Class B

        Upon the liquidation, dissolution or winding up of the Company, holders of Class A Common Stock, Class B Common Stock and Class C Common Stock are entitled to receive ratably the assets available for distribution to the stockholders after the rights of holders of shares of preferred stock have been satisfied.

Other Matters

        Shares of Class A Common Stock, Class B Common Stock and Class C Common Stock have no preemptive rights pursuant to the terms of our amended and restated certificate of incorporation and amended and restated bylaws. There are no redemption or sinking fund provisions applicable to shares of Class A Common Stock, Class B Common Stock or Class C Common Stock. All outstanding shares of Class A Common Stock and of Class B Common Stock are fully paid and non-assessable.

Listing

        Our Class A Common Stock is listed on The Nasdaq Global Select Market under the symbol "ANGI."

Transfer Agent and Registrar

        The transfer agent and registrar for our Class A Common Stock is Computershare Trust Company, N.A.

Preferred Stock

        Pursuant to our amended and restated certificate of incorporation, shares of preferred stock are issuable from time to time, in one or more series, with the designations of the series, the voting rights of the shares of the series (if any), the powers, preferences and relative, participation, optional or other special rights (if any), and any qualifications, limitations or restrictions thereof as our board of directors from time to time may adopt by resolution (and without further stockholder approval, subject to any limitation imposed by Nasdaq Rules). The rights, preferences and privileges of such preferred stock may be greater than, and may adversely affect, the rights of our common stock. Each series will consist of that number of shares as will be stated and expressed in the certificate of designations providing for the issuance of the preferred stock of the series.

Anti-Takeover Effects of Provisions of our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws and Other Agreements

        Certain provisions of the Delaware General Corporation Law (the "DGCL") and certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws summarized below may be deemed to have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in such stockholder's best interests, including attempts that might result in a premium being paid over the market price for the shares held by our stockholders.

Multi-Class Structure

        As discussed above, each share of Class B Common Stock has ten votes per share, while each share of Class A Common Stock (the only class of our stock that is publicly traded) has one vote per share. Except as provided in our amended and restated certificate of incorporation or by the DGCL, the holders of Class A Common Stock and the holders of Class B Common Stock vote on all matters (including the election of directors) together as one class. Our Class C Common Stock, of which no shares are outstanding, do not have any voting rights. IAC owns and controls all of the outstanding shares of Class B Common Stock, which at this time constitutes a substantial majority of both the total voting power and the total number of shares of our total outstanding capital stock. Even if IAC in the future owns significantly less than 50% of our total outstanding capital stock, because of the multi-class structure of our common stock and the higher relative voting rights of Class B Common Stock compared to Class A Common Stock, IAC will be able to control all matters in which the Class A Common Stock and the Class B Common Stock vote together as one class that are submitted to our stockholders for approval. This concentrated control could discourage others from initiating any potential merger, takeover or other change of control transaction that other stockholders may view as beneficial.

Director Vacancies

        The DGCL provides that board vacancies and newly created directorships may be filled by a majority of the directors then in office (even though less than a quorum) or by a sole remaining director unless (i) otherwise provided in the certificate of incorporation or bylaws of the corporation or (ii) the certificate of incorporation directs that a particular class of stock is to elect such director, in which case a majority of the other directors elected by such class, or a sole remaining director elected by such class, will fill such vacancy.

        Our amended and restated bylaws provide that vacancies and newly created directorships may be filled by the vote of a majority of the remaining directors elected by the stockholders who vote on such directorship (even if less than a quorum) or the vote or written consent of a majority of the voting power of the shares of our stock issued and outstanding and entitled to vote on such directorship (subject to the provisions of the Investor Rights Agreement, dated September 29, 2017 (the "Investor Rights Agreement"), by and between us and IAC, concerning two ANGI-Designated Directors (as such term is defined in the Investor Rights Agreement)).

No Cumulative Voting

        Under the DGCL, cumulative voting for elections of directors is not permitted unless the corporation's certificate of incorporation specifically provides for it. Our amended and restated certificate of incorporation does not provide for cumulative voting.

Special Meetings of Stockholders

        Under the DGCL, a special meeting of stockholders may be called by the board of directors or by such other persons as may be authorized in the certificate of incorporation or the bylaws of the corporation.

        Our amended and restated bylaws provide that special meetings of the stockholders may be called by the chairman of our board of directors or by a majority of our directors. Our stockholders, however, may not call for a special meeting of the stockholders.

Amending Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

        Under the DGCL, a certificate of incorporation may be amended if: (i) the board of directors adopts a resolution setting forth the proposed amendment, declares the advisability of the amendment and directs that it be submitted to a vote at a meeting of stockholders (except that, unless required by the certificate of incorporation, no meeting or vote of stockholders is required to adopt an amendment for certain specified changes) and (ii) the holders of a majority of shares of stock entitled to vote on the matter approve the amendment, unless the certificate of incorporation requires the vote of a greater number of shares. If a class vote on the amendment is required by the DGCL, or by the certificate of incorporation, approval by a majority of the outstanding shares of stock of the class is required, unless a greater proportion is specified in the certificate of incorporation or by other provisions of the DGCL. Our amended and restated certificate of incorporation provides that we reserve the right to amend, alter, change or repeal any provision contained in the certificate of incorporation, as prescribed by the DGCL.

        Under the DGCL, the board of directors may adopt, amend or repeal a corporation's bylaws if so authorized in the certificate of incorporation. The stockholders of a Delaware corporation also have the power to adopt, amend or repeal bylaws.

        Our amended and restated certificate of incorporation and amended and restated bylaws allow the board of directors to adopt, amend or repeal the bylaws by the vote of a majority of all directors. Under the Investor Rights Agreement, however, up until the date on which the 2020 annual meeting of our stockholders is held, IAC has agreed not to vote in favor of any amendments to our certificate of incorporation or bylaws that would be inconsistent with certain provisions of the Investor Rights Agreement and would adversely affect the rights of holders of Class A Common Stock, other than as may be approved by the audit committee of our board of directors and a majority of the holders of Class A Common Stock.

Authorized but Unissued Shares

        Delaware companies are permitted to authorize shares that may be issued in the future. A substantial number of unissued shares of our Class A Common Stock, Class B Common Stock, Class C Common Stock and preferred stock are available for future issuances by our board of directors without stockholder approval, subject to any limitations imposed by Nasdaq Rules. Issuances of these shares could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of any authorized but unissued and unreserved Class A Common Stock, Class B Common Stock, Class C Common Stock and preferred stock could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Jurisdiction

        Our amended and restated bylaws provide that a state court located within Delaware, or if no state court located within Delaware has jurisdiction, the federal district court for the District of Delaware, shall be the exclusive forum for all of the following: (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for or based on breach of fiduciary duty owed by any current or former director or officer or other employee of the Company to us or to our stockholders, (iii) any action asserting a claim against us or any of our current or former directors, officers or other employees pursuant to the DGCL, our certificate of incorporation, or our bylaws, (iv) any action asserting a claim relating to or involving us that is governed by the internal affairs doctrine or (v) any action asserting an "internal corporate claim," as defined under the DGCL.

Limitation on Liability and Indemnification of Directors and Officers

        Under the DGCL, subject to specified limitations in the case of derivative suits brought by a corporation's stockholders in its name, a corporation may indemnify any person who is made or is threatened to be made a party to any action, suit or proceeding on account of being a director, officer, employee or agent of the corporation (or was serving at the request of the corporation in such capacity for another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with the action, suit or proceeding, provided that there is a determination that: (i) the individual acted in good faith and in a manner the individual reasonably believed to be in or not opposed to the best interest of the corporation and (ii) in a criminal action or proceeding, the individual had no reasonable cause to believe his or her conduct was unlawful. Without court approval, however, no indemnification may be made in respect of any derivative action in which an individual is adjudged liable to the corporation, except to the extent the Delaware Court of Chancery or the court in which such action or suit was brought determines upon application that, despite the adjudication but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified.

        The DGCL requires indemnification of directors and officers for expenses (including attorneys' fees) actually and reasonably relating to a successful defense on the merits or otherwise of a derivative or third party action.

        Under DGCL, a corporation may advance expenses relating to the defense of any proceeding to directors and officers upon the receipt of an undertaking by or on behalf of the individual to repay such amount if it is ultimately determined that such person is not entitled to be indemnified.

        The DGCL permits the adoption of a provision in a corporation's certificate of incorporation limiting or eliminating the monetary liability of a director to a corporation or its stockholders by reason of a director's breach of the fiduciary duty of care. The DGCL does not permit any limitation of the liability of a director for: (i) breaching the duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith, (iii) engaging in intentional misconduct or a known violation of law, (iv) obtaining an improper personal benefit from a transaction or (v) paying a dividend or approving a stock repurchase or redemption that was illegal under applicable law.

        In addition, our amended and restated certificate of incorporation provides that we must indemnify our directors and officers to the fullest extent authorized by law. Under our amended and restated bylaws, we are also expressly required to advance certain expenses to our directors and officers and are permitted to carry directors' and officers' insurance providing indemnification for our directors and officers for some liabilities.

Waiver of Corporate Opportunity of IAC and Officers and Directors of IAC

        The DGCL permits the adoption of a provision in a corporation's certificate of incorporation renouncing any interests or expectancy of a corporation in, or in being offered an opportunity to participate in, specified business opportunities or specified classes or categories of business opportunities that are presented to the corporation or one or more of its officers, director or stockholders.

        Our amended and restated certificate of incorporation includes a "corporate opportunity" provision that renounces any of our interests or expectancy: (i) to participate in any business of IAC or (ii) in any potential transaction or matter that may constitute a corporate opportunity for both (a) IAC and (b) us. Under this provision, we further recognize that (1) any of our directors or officers who are also officers, directors, employees or other affiliates of IAC or its affiliates (except that we will not be deemed affiliates of IAC or its affiliates for the purposes of this provision) and (2) IAC itself has no

15

Table of Contents

duty to offer or communicate information regarding such a corporate opportunity. The provision generally provides that neither IAC nor our officers or directors who are also officers or directors of IAC or its affiliates will be liable to us or our stockholders for breach of any fiduciary duty by reason of (i) such person's participation in any business on behalf of IAC or (ii) the fact that any such person pursues or acquires any corporate opportunity for the account of IAC or its affiliates, directs or transfers such corporate opportunity to IAC or its affiliates, or does not communicate information regarding such corporate opportunity to us. This renunciation does not extend to corporate opportunities expressly offered to one of our officers or directors solely in his or her capacity as an officer or director of us.

        A selling stockholder that is an entity may elect to make an in-kind distribution of shares of Class A Common Stock, on a pro rata basis or otherwise, to its members, general or limited partners or shareholders pursuant to the registration statement of which this prospectus is a part by delivering a

17

Table of Contents

prospectus. To the extent that such members, general or limited partners or shareholders are not affiliates of ours, such members, partners or shareholders would thereby receive freely tradable shares of Class A Common Stock pursuant to the distribution through a registration statement. Additionally, to the extent that entities, members, partners or shareholders who are affiliates of ours received shares in any such distribution, such affiliates will also be selling stockholders and will be entitled to sell shares of Class A Common Stock pursuant to this prospectus.

        The selling stockholders may enter into sale, forward-sale and derivative transactions with third parties, or may sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those sale, forward-sale or derivative transactions, the third parties may sell securities covered by this prospectus or the applicable prospectus supplement, including in short sale transactions and by issuing securities that are not covered by this prospectus but are exchangeable for or represent beneficial interests in the Class A Common Stock. The third parties may also use shares received under those sale, forward-sale or derivative arrangements or shares pledged by the selling stockholder or borrowed from the selling stockholders or others to settle such third-party sales or to close out any related open borrowings of common stock. The third parties may deliver this prospectus in connection with any such transactions. Any third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment to the registration statement of which this prospectus is a part).

        In connection with sales of shares of Class A Common Stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares in the course of hedging in positions they assume. The selling stockholders may also sell shares of Class A Common Stock short and deliver shares covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also enter into option or other transactions with broker-dealers which require the delivery of securities to the broker-dealer. The broker-dealer may then resell or otherwise transfer such securities pursuant to this prospectus. The selling stockholders may also loan or pledge shares of Class A Common Stock to broker-dealers that in turn may sell or effect distributions of such shares. Such borrower or pledgee may also transfer those shares of Class A Common Stock to investors in our securities or the selling stockholders' securities or in connection with the offering of other securities not covered by this prospectus.

        The selling stockholders may also transfer, donate or gift shares of Class A Common Stock in other circumstances, in which case the pledgees, donees, transferees, assignees and successors-in-interest will be selling stockholders under this prospectus.

        If the selling stockholders sell shares of Class A Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). The selling stockholders and any broker-dealer participating in the distribution of the shares of Class A Common Stock may be deemed to be "underwriters" within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Class A Common Stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of Class A Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.

We have agreed to indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, relating to the registration of the shares offered by this prospectus.
