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.

SELLING STOCKHOLDERS

        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. Except as otherwise indicated, we believe that the selling stockholders have sole voting and investment power with respect to all shares of Class A Common Stock shown as beneficially owned by

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 Common Stock, or in the event of any merger, consolidation or other reorganization of the Company with another corporation. Upon the conversion of a share of Class B Common Stock into a share of

11

---

Table of Contents

Class A Common Stock, the applicable share of Class B Common Stock will be retired and will not be subject to reissue. Shares of Class A Common Stock and shares of Class C Common Stock have no conversion rights.

Liquidation Rights

        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.

Table of Contents

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.

PLAN OF DISTRIBUTION

        The selling stockholders, and the pledgees, donees, transferees, assignees, successors and others who later come to hold any of the selling stockholders' interests in our Class A Common Stock other than through a public sale, may, in accordance with the Registration Rights Agreement, sell all or a portion of the shares of Class A Common Stock offered hereby from time to time in the future. If the shares of Class A Common Stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent's commissions. The shares of Class A Common Stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, pursuant to one or more of the following methods:

•

purchases by underwriters, dealers and agents who may receive compensation in the form of underwriting discounts or commissions or agent commissions from the selling stockholders and/or the purchasers of the shares for whom they may act as agent;



•

any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;



•

the over-the-counter market;



•

transactions otherwise than on these exchanges or systems or in the over-the-counter market;



•

the writing of options, whether such options are listed on an options exchange or otherwise;



•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;



•

block trades, including transactions in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction, or in crosses, in which the same broker acts as an agent on both sides of the trade;



•

purchases by a broker-dealer or market maker, as principal, and resale by the broker-dealer for its account;



•

an exchange distribution in accordance with the rules of the applicable exchange;



•

public or privately negotiated transactions;



•

the pledge of shares for any loan or obligation, including pledges to brokers or dealers who may from time to time effect distributions of such shares;



•

short sales or transactions to cover short sales;



•

broker-dealers may agree with the selling stockholder to sell a specified number of such shares at a stipulated price per share;



•

sales pursuant to Rule 144 under the Securities Act;



•

transactions in which broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;



•

a combination of any such methods of sale; and



•

any other method permitted pursuant to applicable law.

        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.

        Under the securities laws of some states, shares of Class A Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states shares of Class A Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

        There can be no assurance that any selling stockholders will sell any or all of its shares of Class A Common Stock registered pursuant to the registration statement of which this prospectus forms a part.

        The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934 (the "Exchange Act") and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any shares of Class A Common Stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of shares of Class A Common Stock to engage in market-making activities with respect to shares of Class A Common Stock. All of the foregoing may affect the marketability of shares of Class A Common Stock and the ability of any person or entity to engage in market-making activities with respect to shares of Class A Common Stock.

        The selling stockholders will receive all of the net proceeds from the sale of any shares of Class A Common Stock under this prospectus. We are not selling any shares of Class A Common Stock under this prospectus and we will not receive any proceeds from the sale of shares of our Class A Common Stock by the selling stockholders. Pursuant to the Registration Rights Agreement, we are obligated to pay the cost of registering any offer and sale of the shares of Class A Common Stock covered by this prospectus, as well as certain related expenses; however, the selling stockholders are responsible for all discounts, selling commissions and other costs related to the offer and sale of their shares of Class A Common Stock pursuant to this prospectus. 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.

        In addition, we or the selling stockholders may agree to indemnify any underwriters, broker-dealers and agents against or contribute to any payments the underwriters, broker-dealers or agents may be required to make with respect to civil liabilities, including liabilities under the Securities Act. Underwriters, broker-dealers and agents and their affiliates are permitted to be customers of, engage in transactions with, or perform services for us and our affiliates or the selling stockholders or their affiliates in the ordinary course of business.

PART II INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.    Other Expenses of Issuance and Distribution.

        The expenses relating to the registration of the securities will be borne by the registrant.

Item 15.    Indemnification of Directors and Officers.

        Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL (regarding, among other things, the payment of unlawful dividends or unlawful stock purchases or redemptions), or (4) for any transaction from which the director derived an improper personal benefit. Our amended and restated certificate of incorporation provides for such limitation of liability.

        Section 145(a) of the DGCL empowers a corporation to indemnify any director, officer, employee or agent, or former director, officer, employee or agent, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of such person's service as a director, officer, employee or agent of the corporation, or such person's service, at the corporation's request, as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding; provided that such director or officer acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation; and, with respect to any criminal action or proceeding, provided that such director or officer had no reasonable cause to believe his conduct was unlawful.

        Section 145(b) of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another enterprise, against expenses (including attorneys' fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit; provided that such director or officer acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such

director or officer shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such director or officer is fairly and reasonably entitled to indemnity for such expenses that the court shall deem proper. Notwithstanding the preceding sentence, except as otherwise provided in our amended and restated bylaws, we will be required to indemnify any such person in connection with a proceeding (or part thereof) commenced by such person only if the commencement of such proceeding (or part thereof) by any such person was authorized by our board of directors.

        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.

Item 16.    List of Exhibits.

        See Exhibits Index, which is incorporated herein by reference.

Item 17.    Undertakings.

(a)

The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

        provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-2

---

Table of Contents

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.



(4)

That, for the purpose of determining liability under the Securities Act to any purchaser:



(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and



(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.



(5)

That, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.



(6)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

ANGI Homeservices Inc.
14023 Denver West Parkway
Building 64
Golden, CO 80401

Ladies and Gentlemen:

        We have acted as special counsel to ANGI Homeservices Inc., a Delaware corporation (the "Company"), in connection with the registration statement on Form S-3 (the "Registration Statement") to be filed on the date hereof by the Company with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"). The Registration Statement relates to the resale from time to time of up to 7,482,167 shares (the "Shares") of Class A Common Stock, par value $0.001 per share, of the Company to be sold by the selling stockholders named therein (the "Selling Stockholders"). We have been advised that the Shares were issued to the Selling Stockholders pursuant to the Agreement and Plan of Merger, dated as of September 29, 2018 (the "Merger Agreement"), by and among the Company, Hamlet Merger Sub, Inc., Handy Technologies, Inc. and Shareholder Representative Services LLC.

        This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

        In rendering the opinion stated herein, we have examined and relied upon the following:

        (a)   the Registration Statement;

        (b)   an executed copy of the Merger Agreement;

        (c)   an executed copy of a certificate of Gregg Winiarski, Interim Chief Legal Officer of the Company, dated the date hereof (the "Officer's Certificate");

        (d)   a copy of the Company's Amended and Restated Certificate of Incorporation certified by the Secretary of State of the State of Delaware as of October 22, 2018, and certified pursuant to the Officer's Certificate;

        (e)   a copy of the Company's Amended and Restated Bylaws, as amended and in effect as of the date hereof and certified pursuant to the Officer's Certificate; and

        (f)    a copy of certain resolutions of the Board of Directors of the Company, adopted on September 13, 2018, certified pursuant to the Officer's Certificate.

        We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and the Selling Stockholders and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company, the Selling Stockholders and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinion stated below.

        In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinion stated herein that we did not independently establish or verify, we have relied upon statements

and representations of officers and other representatives of the Company and the Selling Stockholders and others and of public officials, including those in the Officer's Certificate and the factual representations and warranties set forth in the Merger Agreement.

        We do not express any opinion with respect to the laws of any jurisdiction other than the General Corporation Law of the State of Delaware (the "DGCL").

        Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that the Shares have been duly authorized by all requisite corporate action on the part of the Company under the DGCL and have been validly issued and are fully paid and nonassessable.

        In addition, in rendering the foregoing opinion we have assumed that (i) the Company received the consideration for the Shares set forth in the Merger Agreement and the applicable board resolutions and (ii) the issuance of the Shares has been registered in the Company's share registry.

        We hereby consent to the reference to our firm under the heading "Legal Matters" in the prospectus forming part of the Registration Statement. We also hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations. This opinion is expressed as of the date hereof unless otherwise expressly stated, and we disclaim any undertaking to advise you of any subsequent changes in the facts stated or assumed herein or of any subsequent changes in applicable laws.
