 Business Description
        Black Knight is a leading provider of software, data and analytics solutions to the mortgage and consumer loan, real estate and capital market verticals. We believe we differentiate ourselves by the breadth and depth of our comprehensive, integrated solutions and the insight we provide to our clients.
        We have market-leading positions in mortgage processing and software solutions combined with comprehensive real estate data and extensive analytic capabilities. Our solutions are utilized by U.S. mortgage originators and mortgage servicers, as well as other financial institutions, investors and real estate professionals, to support mortgage lending and servicing operations, analyze portfolios and properties, operate more efficiently, meet regulatory compliance requirements and mitigate risk.
 Share Repurchase
        We intend to purchase from the underwriter 2,000,000 shares of our common stock that are subject to this offering at a price per share equal to the price per share paid by the underwriter to the selling shareholders in this offering. We refer to this repurchase as the "share repurchase." The share repurchase is part of our existing equity repurchase program initially approved by our board of directors on January 31, 2017. After giving effect to the share repurchase, we will have remaining authorization to repurchase up to an additional 6,809,879 shares of our common stock under the repurchase program. We intend to fund the share repurchase with cash on hand and borrowings under our revolving credit facility. The closing of the share repurchase is contingent on the closing of this offering.
        The description and the other information in this prospectus supplement regarding the share repurchase is included in this prospectus supplement solely for informational purposes. Nothing in this prospectus supplement should be construed as an offer to sell, or the solicitation of an offer to buy, any of our common stock subject to the share repurchase.
 Corporate Reorganization
        Pursuant to a reorganization and certain mergers described below and in our Current Report on Form 8-K12B, filed with the SEC on October 2, 2017, the Company became the public parent holding company of Black Knight Financial Services, Inc. (the "Predecessor") (the "Reorganization").
        The Reorganization was effected by the following on September 29, 2017: (i) the contribution by Fidelity National Financial, Inc. ("FNF") of (x) all of the shares of Class B common stock of the Predecessor that Black Knight Holdings, Inc. ("BKHI") owned and (y) all of the class A units of Black Knight Financial Services, LLC ("BKFS LLC") that BKHI owned to New BKH Corp. ("New BKH"), a

direct wholly-owned subsidiary of BKHI, (ii) the distribution of the shares of New BKH common stock to the holders of the FNF Group tracking stock of FNF, followed by (iii) the mergers of the Predecessor and New BKH into wholly-owned subsidiaries of the Company (collectively, the "Transactions"). In the Transactions, the outstanding shares of the Predecessor's Class A common stock and New BKH common stock were converted into shares of the Company's common stock on a one-for-one basis as set forth in the Agreement and Plan of Merger dated as of June 8, 2017 by and among the Company, FNF, BKHI, New BKH, New BKH Merger Sub, Inc. and BKFS Merger Sub, Inc.

Under the organizational documents of the Company, the rights of the holders of shares of the Company's common stock are substantially the same as the rights of former holders of the Predecessor's Class A common stock.

Adjusted Revenues, Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP financial measures, which we believe are useful for investors in evaluating our overall financial performances. Black Knight believes these measures provide useful information about operating results, enhance the overall understanding of past financial performance and future prospects and allow for greater

 RISK FACTORS
        An investment in our common stock involves a high degree of risk. You should carefully consider the information contained in this prospectus supplement and the accompanying prospectus before making an investment in our common stock. In addition, you should read and consider the risk factors included in the documents incorporated by reference in this prospectus supplement, including our Annual Report on Form 10-K for the year ended December 31, 2016 and our Quarterly Report on Form 10-Q for the quarter September 30, 2017. See "Where You Can Find More Information; Incorporation of Certain Documents by Reference." If any risks actually occur, our business, financial condition and results of operations may be materially adversely affected. In such an event, the trading price of our common stock could decline and you could lose part or all of your investment.
 Risks Related to this Offering and Ownership of Our Common Stock
 The market price of our common stock may be volatile and you may lose all or part of your investment.
        The market price of our common stock could fluctuate significantly and you may not be able to resell your shares at or above the offering price. Those fluctuations could be based on various factors in addition to those otherwise described in this prospectus, including those listed in "Risk Factors" included in our Annual Report on Form 10-K for the year ended December 31, 2016 and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 and the following:
•
our operating performance and the performance of our competitors and fluctuations in our operating results; 

•
the public's reaction to our press releases, our other public announcements and our filings with the SEC; 

•
global, national or local economic, legal and regulatory factors unrelated to our performance; 

•
announcements of positive news by us or our competitors, such as announcements of new products, services, strategic investments or acquisitions; 

•
announcements of negative news by us or our competitors, such as announcements of poorer than expected results of operations, data breaches or significant litigation; 

•
actual or anticipated variations in our or our competitors' operating results, and our and our competitors' growth rates; 

•
failure by us or our competitors to meet analysts' projections or guidance that we or our competitors may give the market; 

•
changes in laws or regulations, or new interpretations or applications of laws and regulations, that are applicable to our business; 

•
changes in accounting standards, policies, guidance, interpretations or principles; 

•
the arrival or departure of key personnel; 

•
the number of shares to be publicly traded after this offering and the share repurchase; 

•
future sales or issuances of our common stock, including sales, distributions or issuances by us, our officers or directors and our significant shareholders, including Thomas H. Lee Partners, L.P. ("THL") and certain of their affiliates; and 

•
other developments affecting us, our industry or our competitors.
        In addition, in recent years the stock market has experienced significant price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many
S-8

Table of Contents
companies. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. These broad market fluctuations, as well as general economic, political and market conditions such as recessions or interest rate changes, may cause declines in the market price of our common stock and you may not realize any return on your investment in us and may lose some or all of your investment.
        As we primarily operate in a single industry, we are especially vulnerable to these factors to the extent that they affect our industry or our products. In the past, securities class action litigation has often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management's attention and resources, and could also require us to make substantial payments to satisfy judgments or to settle litigation.
 Future sales of our common stock in the public market could cause the market price of our common stock to decrease significantly.
        Sales of substantial amounts of our common stock in the public market following this offering by our existing shareholders or by persons who acquire shares in this offering may cause the market price of our common stock to decrease significantly. These issuances, or the possibility that these issuances may occur, may also make it more difficult for us to raise additional capital by selling equity securities in the future, at a time and price that we deem appropriate.
        In connection with this offering, our executive officers, directors, other than William P. Foley, II, and the selling shareholders entered into lock-up agreements with the underwriter of this offering that, subject to certain exceptions, prohibit the signing party from selling, contracting to sell or otherwise disposing of any common stock or securities that are convertible or exchangeable for common stock in excess of 10% (subject to certain exceptions) of the shares beneficially owned by such signing party, or entering into any arrangement that transfers the economic consequences of ownership of our common stock for at least 30 days from the date of this prospectus filed in connection with this offering, although the underwriter may, in its sole discretion and at any time without notice, release all or any portion of the securities subject to these lock-up agreements. Upon a request to release any shares subject to a lock-up, the underwriter would consider the particular circumstances surrounding the request including, but not limited to, the length of time before the lock-up expires, the number of shares requested to be released, reasons for the request, the possible impact on the market for our common stock and whether the holder of our shares requesting the release is an officer, director or other affiliate of ours. See "Underwriting."
        Additionally, we have adopted an equity incentive plan pursuant to which stock options to purchase shares of common stock and other stock-based awards may be issued in the future from time to time to our officers, directors and employees.
        As restrictions on resale expire or as shares are registered, our share price could drop significantly if the holders of these restricted or newly registered shares sell them or are perceived by the market as intending to sell them. These sales might also make it more difficult for us to raise capital through the sale of equity securities in the future at a time and at a price that we deem appropriate.
 If securities or industry analysts publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.
        The trading market for our common stock is influenced in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrades our common stock or publishes inaccurate or unfavorable research about our business, our stock price could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price and trading volume to decline.

Table of Contents
 Our charter and bylaws and provisions of Delaware law may discourage or prevent strategic transactions, including a takeover of our company, even if such a transaction would be beneficial to our shareholders.
        Provisions contained in our charter and bylaws and provisions of the Delaware General Corporate Law, or DGCL, could delay or prevent a third party from entering into a strategic transaction with us, as applicable, even if such a transaction would benefit our shareholders. For example, our charter and bylaws:
•
divide our board of directors into three classes with staggered three-year terms, which may delay or prevent a change of our management or a change of control; 

•
authorize the issuance of "blank check" preferred stock that could be issued by us upon approval of our board of directors to increase the number of outstanding shares of capital stock, making a takeover more difficult and expensive; 

•
provide that directors may be removed from office only for cause and that any vacancy on our board of directors may only be filled by a majority of our directors then in office, which may make it difficult for other shareholders to reconstitute our board of directors; 

•
provide that special meetings of the shareholders may be called only upon the request of a majority of our board of directors or by our chairman of the board of directors or chief executive officer; and 

•
require advance notice to be given by shareholders for any shareholder proposals or director nominees.
        By virtue of not opting out of Section 203 of the DGCL in our amended and restated certificate of incorporation, we are subject to Section 203 of the DGCL, which prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the time the shareholder became an interested stockholder, subject to certain exceptions, including if, prior to such time, the board of directors approved the business combination or the transaction which resulted in the shareholder becoming an interested stockholder. "Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the "interested stockholder." Subject to various exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns, or within three years did own, 15% or more of the corporation's outstanding voting stock. These restrictions generally prohibit or delay the accomplishment of mergers or other takeover or change of control attempts that are not approved by a company's board of directors.
        These restrictions and provisions could keep us from pursuing relationships with strategic partners and from raising additional capital, which could impede our ability to expand our business and strengthen our competitive position. These restrictions could also limit shareholder value by impeding a sale of us.
 We do not intend to pay dividends for the foreseeable future.
        We may retain future earnings, if any, for future operations, expansion and debt repayment. We have not paid cash dividends to date and have no current plans to pay any cash dividends for the foreseeable future. As a result of our current dividend policy, you may not receive any return on an investment in our common stock unless you sell our common stock for a price greater than that which you paid for it. Any future determination to declare and pay cash dividends will be at the discretion of our board of directors and will depend on, among other things, our financial condition, results of operations, cash requirements, contractual restrictions and such other factors as our board of directors deems relevant. Our ability to pay dividends depends on our receipt of cash dividends from our operating subsidiaries, which may further restrict our ability to pay dividends as a result of the laws of their jurisdiction of organization or agreements of our subsidiaries, including agreements governing our indebtedness. Existing or future agreements governing our indebtedness may limit our ability to pay dividends.

 DIVIDEND POLICY
        We do not intend to pay cash dividends on our common stock in the foreseeable future. Any future determination to pay dividends will be at the discretion of our board of directors and subject to, among other things, our compliance with applicable law, and depending on, among other things, our results of operations, financial condition, level of indebtedness, capital requirements, contractual restrictions, restrictions in our debt agreements, business prospects and other factors that our board of directors may deem relevant. We will evaluate future quarterly dividend payment amounts based on, among other things, our cash flow and liquidity position. The payment, including timing and amount, of any dividends will be at the discretion of our board of directors.
        Our ability to pay dividends depends on our receipt of cash dividends from our operating subsidiaries, including BKFS LLC, which may further restrict our ability to pay dividends as a result of the laws of their jurisdiction of organization or agreements of our subsidiaries, including agreements governing our indebtedness. Future agreements governing our indebtedness may also limit our ability to pay dividends. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Description of Certain Indebtedness" incorporated in this prospectus supplement by reference from our Annual Report on Form 10-K for a description of the restrictions on our ability to pay dividends.
        You may need to sell your shares of our common stock to realize a return on your investment, and you may not be able to sell your shares at or above the price you paid for them.

 MATERIAL U.S. FEDERAL INCOME AND ESTATE TAX CONSIDERATIONS FOR
NON-U.S. HOLDERS
        The following is a general discussion of the material U.S. federal income and estate tax consequences to non-U.S. holders (as defined below) of the purchase, ownership and disposition of our common stock. This discussion does not provide a complete analysis of all potential U.S. federal income tax and estate tax considerations relating thereto. This description is based on the Internal Revenue Code ("IRC"), existing and proposed U.S. Treasury regulations promulgated thereunder, administrative pronouncements, judicial decisions, and interpretations of the foregoing, all as of the date hereof and all of which are subject to change, possibly with retroactive effect. In particular, recently proposed legislation may impact the U.S. federal tax consequences to a holder of our common stock. This discussion is limited to non-U.S. Holders who hold shares of our common stock as capital assets within the meaning of Section 1221 of the IRC. Moreover, this discussion is for general information only and does not address all of the tax consequences that may be relevant to you in light of your particular circumstances, nor does it discuss special tax provisions, which may apply to you if you are subject to special treatment under U.S. federal income tax laws, such as for certain financial institutions or financial services entities, insurance companies, tax-exempt entities, dealers in securities or currencies, entities that are treated as partnerships for U.S. federal income tax purposes, "controlled foreign corporations," "passive foreign investment companies," former U.S. citizens or long-term residents, persons deemed to sell common stock under the constructive sale provisions of the IRC, and persons that hold common stock as part of a straddle, hedge, conversion transaction, or other integrated investment. In addition, this summary does not address the Medicare tax on certain investment income or any state, local or foreign taxes or any U.S. federal tax laws other than U.S. federal income tax laws and estate tax laws.
        You are urged to consult with your own tax advisor concerning the U.S. federal income tax and estate tax consequences of acquiring, owning and disposing of our common stock, as well as the application of any state, local, and foreign income and other tax laws.
        As used in this section, a "non-U.S. holder" is a beneficial owner of our common stock that is not, for U.S. federal income tax purposes:
•
an individual who is a citizen or resident of the United States, 

•
a corporation (or other entity taxable as a corporation) that is created or organized in or 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 (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a domestic trust.
        If you are an individual, you are a resident alien if you are a lawful permanent resident of the United States (e.g., a green card holder) and you may, in many cases, be deemed to be a resident alien, as opposed to a nonresident alien, by virtue of being present in the United States for at least 31 days in the calendar year and for an aggregate of at least 183 days during a three-year period ending in the current calendar year. For these purposes, all the days present in the current year, one-third of the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year are counted. Resident aliens are subject to U.S. federal income tax as if they were U.S. citizens. Such an individual is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the purchase, ownership or disposition of our common stock.

        If a partnership or other pass-through entity is a beneficial owner of our common stock, the tax treatment of a partner in the partnership or an owner of the other pass-through entity will depend upon the status of the partner or owner and the activities of the partnership or other pass-through entity. Any partner in a partnership or owner of a pass-through entity holding shares of our common stock should consult its own tax advisor.
         INVESTORS CONSIDERING THE PURCHASE OF OUR COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE CONSEQUENCES OF OTHER FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS, AND APPLICABLE TAX TREATIES.
 Distributions on Common Stock
        If we pay distributions on shares of our common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital that is applied against and reduces, but not below zero, a non-U.S. holder's adjusted tax basis in shares of our common stock. Any remaining excess will be treated as gain realized on the sale or other disposition of our common stock. See "—Dispositions of Common Stock."
        Any dividend paid to a non-U.S. holder on our common stock will generally be subject to U.S. federal withholding tax at a 30% rate. The withholding tax might not apply, however, or might apply at a reduced rate, under the terms of an applicable income tax treaty between the United States and the non-U.S. holder's country of residence. You should consult your tax advisors regarding your entitlement to benefits under a relevant income tax treaty. Generally, in order for us or our paying agent to withhold tax at a lower treaty rate, a non-U.S. holder must certify its entitlement to treaty benefits. A non-U.S. holder generally can meet this certification requirement by providing an Internal Revenue Service ("IRS") Form W-8BEN or IRS Form W-8BEN-E, as applicable, to us or our paying agent. If the non-U.S. holder holds the stock through a financial institution or other agent acting on the holder's behalf, the holder will be required to provide appropriate documentation to the agent. The holder's agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. A non-U.S. holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.
        Dividends received by a non-U.S. holder that are effectively connected with a U.S. trade or business conducted by the non-U.S. holder and, if required by an applicable income tax treaty between the United States and the non-U.S. holder's country of residence, are attributable to a permanent establishment (or, in certain cases involving individual holders, a fixed base) maintained by the non-U.S. holder in the United States, are not subject to such withholding tax. To obtain this exemption, a non-U.S. holder must provide us with an IRS Form W-8ECI properly certifying such exemption. Such effectively connected dividends, although not subject to withholding tax, are taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits. In addition to the graduated tax described above, such effectively connected dividends received by corporate non-U.S. holders may also 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.

 Dispositions of Common Stock
        Subject to the discussion below on backup withholding and other withholding requirements, gain realized by a non-U.S. holder on a sale, exchange or other disposition of our common stock generally will not be subject to U.S. federal income or withholding tax, unless:
•
the gain (i) is effectively connected with the conduct by the non-U.S. holder of a U.S. trade or business and (ii) if required by an applicable income tax treaty between the United States and the non-U.S. holder's country of residence, is attributable to a permanent establishment (or, in certain cases involving individual holders, a fixed base) maintained by the non-U.S. holder in the United States (in which case the special rules described below apply), 

•
the non-U.S. holder is an individual who is present in the United States for 183 or more days in the taxable year of such disposition and certain other conditions are met (in which case the gain would be subject to a flat 30% tax, or such reduced rate as may be specified by an applicable income tax treaty, which may be offset by certain U.S. source capital losses), or 

•
we are, or have been, a U.S. real property holding corporation, or a USRPHC, for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition of our common stock and the non-U.S. holder's holding period for our common stock.
        Generally, a corporation is a USRPHC if the fair market value of its "United States real property interests" equals 50% or more of the sum of the fair market value of (a) its worldwide real property interests and (b) its other assets used or held for use in a trade or business. The tax relating to stock in a USRPHC does not apply to a non-U.S. holder whose holdings, actual and constructive, amount to 5% or less of our common stock at all times during the applicable period, provided that our common stock is regularly traded on an established securities market. We believe we have not been and are not currently a USRPHC, and do not anticipate being a USRPHC in the future.
        If any gain from the sale, exchange or other disposition of our common stock, (1) is effectively connected with a U.S. trade or business conducted by a non-U.S. holder and (2) if required by an applicable income tax treaty between the United States and the non-U.S. holder's country of residence, is attributable to a permanent establishment (or, in certain cases involving individuals, a fixed base) maintained by such non-U.S. holder in the United States, then the gain generally will be subject to U.S. federal income tax at the same graduated rates applicable to U.S. persons, net of certain deductions and credits. If the non-U.S. holder is a corporation, under certain circumstances, that portion of its earnings and profits that is effectively connected with its U.S. trade or business, subject to certain adjustments, generally would also be subject to a "branch profits tax." The branch profits tax rate is generally 30%, although an applicable income tax treaty between the United States and the non-U.S. holder's country of residence might provide for a lower rate.
 U.S. Federal Estate Tax
        Individuals, or an entity the property of which is includable in an individual's gross estate for U.S. federal estate tax purposes, should note that any of our common stock held at the time of such individual's death will be included in such individual's gross estate for U.S. federal estate tax purposes, and may be subject to U.S. federal estate tax, unless an applicable estate tax treaty provides otherwise.
 Backup Withholding and Information Reporting
        Any dividends that are paid to a non-U.S. holder must be reported annually to the IRS and to the non-U.S. holder. Copies of these information returns also may be made available to the tax authorities of the country in which the non-U.S. holder resides under the provisions of various treaties or agreements for the exchange of information. Dividends paid on our common stock and the gross
S-19

Table of Contents
proceeds from a taxable disposition of our common stock may be subject to additional information reporting and may also be subject to U.S. federal backup withholding if such non-U.S. holder fails to comply with applicable U.S. information reporting and certification requirements. Provision of any IRS Form W-8 appropriate to the non-U.S. holder's circumstances will generally satisfy the certification requirements necessary to avoid the additional information reporting and backup withholding.
        Backup withholding is not an additional tax. Any amounts so withheld under the backup withholding rules will be refunded by the IRS or credited against the non-U.S. holder's U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.
 Other Withholding Taxes
        Provisions commonly referred to as "FATCA" impose withholding of 30% on payments of U.S.-source dividends (including our dividends) and, beginning in 2019, on sales or other proceeds from the disposition of domestic corporate stock (including our stock), paid to "foreign financial institutions" (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. An intergovernmental agreement between the United States and the entity's jurisdiction may modify these requirements. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return containing the required information (which may entail significant administrative burden). Non-U.S. holders should consult their tax advisors regarding the effects of FATCA on their investment in our common stock.
         THE PRECEDING DISCUSSION OF U.S. FEDERAL INCOME TAX AND ESTATE TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY. IT IS NOT TAX ADVICE. EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF PURCHASING, HOLDING AND DISPOSING OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

 UNDERWRITING
        Goldman Sachs & Co. LLC is acting as underwriter of the offering. Subject to the terms and conditions set forth in an underwriting agreement among us, the selling shareholders and the underwriter, the selling shareholders have agreed to sell to the underwriter, and the underwriter has agreed to purchase from the selling shareholders, 5,000,000 shares of common stock.
        Subject to the terms and conditions set forth in the underwriting agreement, the underwriter has agreed to purchase all of the shares of common stock sold under the underwriting agreement if any of these shares are purchased.
        Subject to the completion of this offering, we have agreed to purchase 2,000,000 shares of our common stock that are subject to this offering from the underwriter at a price per share equal to the price per share paid by the underwriter to the selling shareholders in this offering. The closing of the share repurchase is contingent on the closing of this offering.
        We and the selling shareholders have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriter may be required to make in respect of those liabilities.
        The underwriter is offering the shares, subject to prior sale, when, as and if issued to and accepted by it, subject to approval of legal matters by its counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriter of officer's certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
 Commissions and Discounts
        The underwriter is purchasing the shares of common stock from the selling shareholders at $        per share (representing approximately $        aggregate proceeds to the selling shareholders, before expenses). The underwriter proposes to offer the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at a price less a concession not in excess of $            per share. After the initial public offering of the shares, the offering and other selling terms may be changed by the underwriter.
        We will pay the expenses incurred by the selling shareholders in connection with this offering. The expenses of this offering that are payable by us are estimated to be approximately $        .
 No Sales of Similar Securities
        In connection with this offering, we will, and we expect our executive officers, directors, other than Mr. Foley, the selling shareholders and other holders of 5.0% of our outstanding common stock to, enter into lock-up agreements with the underwriter of this offering that, subject to certain exceptions, prohibit the signing party from selling, contracting to sell or otherwise disposing of any common stock in excess of 10% (subject to certain exceptions) of the shares beneficially owned by such signing party, or entering into any arrangement that transfers the economic consequences of ownership of our common stock for at least 30 days (and in the case of the Company, 45 days) from the date of this prospectus supplement filed in connection with this offering, although the underwriter may, in its sole discretion and at any time without notice, release all or any portion of the securities subject to these lock-up agreements. Upon a request to release any shares subject to a lock-up, the underwriter would consider the particular circumstances surrounding the request including, but not limited to, the length of time before the lock-up expires, the number of shares requested to be released, reasons for the request and the possible impact on the market for our common stock and whether the holder of our shares requesting the release is an officer, director or other affiliate of ours. As a result of these lock-up agreements, notwithstanding earlier eligibility for sale under the provisions of Rule 144 under
S-22

the Securities Act, none of these shares would be allowed to be sold until at least 30 days (and in the case of the Company, 45 days) after the date of this prospectus supplement.
 New York Stock Exchange Listing
        Our common stock is listed on the NYSE under the symbol "BKI."
 Price Stabilization, Short Positions
        In connection with this offering, the underwriter may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriter of a greater number of shares than it is required to purchase in this offering. "Covered" short sales are sales made in an amount not greater than the underwriter's option to purchase additional shares described above. The underwriter may close out any covered short position by either exercising its option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which it may purchase shares through the option granted to it. "Naked" short sales are sales in excess of such option. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriter in the open market prior to the completion of this offering.
        Similar to other purchase transactions, the underwriter's purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriter may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.
        Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
 Electronic Distribution
        In connection with this offering, the underwriter or securities dealers may distribute prospectuses by electronic means, such as e-mail.
 Other Relationships
        The underwriter and its affiliates are a full service financial institution 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 us, the selling shareholders and to persons and entities with relationships with us or the selling shareholders, for which the underwriter received or will receive customary fees and expenses.

        The holders of our common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences and privileges of holders of our common stock will be subject to those of the holders of any shares of our preferred stock we may issue in the future.
 Registration Rights
        In connection with our IPO, we entered into a registration rights agreement with certain persons, including subsidiaries of FNF and certain affiliates of Thomas H. Lee Partners, L.P. ("THL"), a Delaware limited partnership, that held shares of our common stock (the "Registration Rights Agreement"). In connection with our reorganization pursuant to the Transactions, on September 29, 2017, Black Knight Financial Services, Inc. assigned its rights and obligations under the Registration Rights Agreement to Black Knight, Inc. The registration statement of which this prospectus forms a part has been requested by the selling shareholders pursuant to their rights under the Registration Rights Agreement.
        The Registration Rights Agreement provides certain shareholders that hold at least 7.5% of our registrable shares of common stock the right to require us to register the number of our shares of common stock requested to be so registered in accordance with the Registration Rights Agreement. In addition, holders of registrable shares of common stock under the Registration Rights Agreement are entitled to request to participate in, or "piggyback" on, registrations of registrable securities for sale by us at any time after this offering. Subject to certain limitations, we are required to include in the registration all securities with respect to which we receive a written request for inclusion in such registration. These registration rights are subject to conditions and limitations, including the right of the underwriters to limit the number of shares to be included in a registration statement and our right to delay, suspend or withdraw a registration statement under specified circumstances. The Registration Rights Agreement also provides that we are required to pay certain expenses of these electing holders relating to such registrations and indemnify them against certain liabilities that may arise under the Securities Act.
 Preferred Stock
        Our board of directors has the authority to issue shares of preferred stock in one or more series and to fix the rights, preferences and limitations thereof, including dividend rights, specification of par value, conversion rights, voting rights, terms of redemption, specification of par value, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the shareholders.
        The issuance of preferred stock may have the effect of delaying, deferring or preventing a change of control of us without further action by the shareholders and may adversely affect the voting and other rights of the holders of common stock. At present, we have no shares of preferred stock issued and outstanding, and we have no plans to issue any preferred stock.

Table of Contents
 Election and Removal of Directors; Vacancies
        Our amended and restated certificate of incorporation provides that our board of directors consist of between one and fourteen directors. The exact number of directors may be fixed from time to time by a majority of our board of directors. In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three classes of directors, with each class constituting, as nearly as possible, one-third of the total number of directors. Each class of directors will be elected for a three-year term. As a result, approximately one-third of our board of directors will be elected each year. There is no limit on the number of terms a director may serve on our board of directors.
 Shareholder Action by Written Consent
        Our amended and restated certificate of incorporation provides that actions required or permitted to be taken by shareholders at an annual or special meeting may be effected without a meeting by written consent. A shareholder seeking to have the shareholders authorize or take action by written consent must deliver requests from the holders of not less than 15% of our common stock, or from the holders of our preferred stock, if the terms of such class or series of preferred stock expressly provide for action by written consent, subject to certain procedural provisions.
 Anti-takeover Effects of our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws
        Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may delay, defer or discourage another party from acquiring control of us. We believe that these provisions, which are summarized below, discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our shareholders. However, they also give our board of directors the power to discourage acquisitions that some shareholders may favor.
 Classified Board of Directors and Related Provisions
        Our amended and restated certificate of incorporation provides that our board of directors must be divided into three classes of directors (each class containing approximately one-third of the total number of directors) serving staggered three-year terms. As a result, approximately one-third of our board of directors is elected each year. This classified board provision prevents a third party who acquires control of a majority of our outstanding voting stock from obtaining control of our board of directors until the second annual shareholders meeting following the date the acquirer obtains the controlling interest. The number of directors constituting our board of directors is determined from time to time by our board of directors. Our amended and restated certificate of incorporation also provides that, subject to any rights of any preferred stock then outstanding, any director may be removed from office at any time but only for cause and only by the affirmative vote of the holders of a majority of the voting power of the shares entitled to vote for the election of directors, considered for this purpose as one class. In addition, our amended and restated certificate of incorporation provides that any vacancy on the board of directors, including a vacancy that results from an increase in the number of directors or a vacancy that results from the removal of a director with cause, may be filled only by a majority of the directors then in office or by an affirmative vote of the sole remaining director. This provision, in conjunction with the provisions of our amended and restated certificate of incorporation authorizing our board of directors to fill vacancies on the board of directors, prevents shareholders from removing incumbent directors without cause and filling the resulting vacancies with their own nominees.

Table of Contents
 Special Meetings
        Our amended and restated certificate of incorporation provides that, except as otherwise required by law, special meetings of the shareholders can only be called by a majority of our entire board of directors or our chairman of the board of directors or chief executive officer. Shareholders may not call a special meeting or require that our board of directors call a special meeting of shareholders.
 Requirements for Advance Notification of Shareholder Meetings, Nominations and Proposals
        Our amended and restated bylaws provide that, if one of our shareholders desires to submit a proposal or nominate persons for election as directors at an annual shareholders' meeting, the shareholder's written notice must be received by us not less than 120 days prior to the anniversary date of the date of the proxy statement for the immediately preceding annual meeting of shareholders. However, if the annual meeting is called for a date that is not within 30 days before or after such anniversary date, notice by a shareholder must be received by us not later than the close of business on the 10th day following the day on which public disclosure of the date of the annual meeting was made. The notice must describe the proposal or nomination and set forth the name and address of, and stock held of record and beneficially by, the shareholder. Notices of shareholder proposals or nominations must set forth the reasons for the proposal or nomination and any material interest of the shareholder in the proposal or nomination and a representation that the shareholder intends to appear in person or by proxy at the annual meeting. Director nomination notices must set forth the name and address of the nominee, arrangements between the shareholder and the nominee and other information required under Regulation 14A of the Exchange Act. The presiding officer of the meeting may refuse to acknowledge a proposal or nomination not made in compliance with the procedures contained in our amended and restated bylaws. The advance notice requirements regulating shareholder nominations and proposals may have the effect of precluding a contest for the election of directors or the introduction of a shareholder proposal if the requisite procedures are not followed and may discourage or deter a third-party from conducting a solicitation of proxies to elect its own slate of directors or to introduce a proposal.
 Authorized but Unissued Shares
        The authorized but unissued shares of our common stock and our preferred stock are available for future issuance without any further vote or action by our shareholders. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of our common stock and our preferred stock could render more difficult or discourage an attempt to obtain control over us by means of a proxy contest, tender offer, merger or otherwise.
 Delaware Anti-Takeover Statute
        By virtue of not opting out of Section 203 of the DGCL in our amended and restated certificate of incorporation, we are subject to Section 203 of the DGCL, which prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the time the shareholder became an interested stockholder, subject to certain exceptions, including if, prior to such time, the board of directors approved the business combination or the transaction which resulted in the shareholder becoming an interested stockholder. "Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the "interested stockholder." Subject to various exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns, or within three years did own, 15% or more of the corporation's outstanding voting stock. These restrictions generally prohibit or delay the accomplishment of mergers or other takeover or change of control attempts that are not approved by a company's board of directors.

 Limitations on Director Liability
        Under the DGCL, we may indemnify any person 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 the fact that he or she is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of 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 in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In addition, Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to liability for unauthorized acquisitions or redemptions of, or dividends on, capital stock) or (iv) for any transaction from which the director derived an improper personal benefit. Our amended and restated certificate of incorporation contains the provisions permitted by Section 102(b)(7) of the DGCL.
 Corporate Opportunities
        To address situations in which officers or directors have conflicting duties to affiliated corporations, Section 122(17) of the DGCL allows a corporation to renounce, in its certificate of incorporation or by action of its board of directors, any interest or expectancy of the corporation in specified classes or categories of business opportunities. As such, and in order to address potential conflicts of interest between us and FNF or THL, our amended and restated certificate of incorporation contains provisions regulating and defining, to the fullest extent permitted by law, the conduct of our affairs as they may involve FNF and THL and FNF's and THL's officers and directors.
        Our amended and restated certificate of incorporation provides that, subject to any written agreement to the contrary, neither FNF nor THL will have a duty to refrain from engaging in the same or similar activities or lines of business that we engage in, and, except as set forth in our amended and restated certificate of incorporation, none of FNF, THL and FNF's and THL's officers and directors will be liable to us or our shareholders for any breach of any fiduciary duty due to any such activities of FNF or THL.
        Our amended and restated certificate of incorporation also provides that we may from time to time be or become a party to and perform, and may cause or permit any subsidiary to be or become a party to and perform, one or more agreements (or modifications or supplements to pre-existing agreements) with FNF or THL. With limited exceptions, to the fullest extent permitted by law, no such agreement, nor the performance thereof in accordance with its terms by us, any of our subsidiaries, FNF or THL, shall be considered contrary to any fiduciary duty to us or our shareholders of any director or officer of ours who is also a director, officer or employee of FNF or THL. With limited exceptions, to the fullest extent permitted by law, no director or officer of ours who is also a director, officer or employee of FNF or THL shall have or be under any fiduciary duty to us or our shareholders to refrain from acting on behalf of us or any of our subsidiaries or on behalf of FNF or THL in respect of any such agreement or performing any such agreement in accordance with its terms.
        Our amended and restated certificate of incorporation further provides that if one of our directors or officers who is also a director or officer of FNF or THL acquires knowledge of a potential
11

Table of Contents
transaction or matter that may be a corporate opportunity for any of FNF, THL or us, the director or officer will have satisfied his or her fiduciary duty to us and our shareholders with respect to that corporate opportunity if he or she acts in a manner consistent with the following policy:
•
a corporate opportunity offered to any person who is an officer of ours and who is also a director but not an officer of FNF or THL, will belong to us unless the opportunity is expressly offered to that person in a capacity other than such person's capacity as one of our officers, in which case it will not belong to us; 

•
a corporate opportunity offered to any person who is a director but not an officer of ours, and who is also a director or officer of FNF or THL, will belong to us only if that opportunity is expressly offered to that person in that person's capacity as one of our directors; and 

•
a corporate opportunity offered to any person who is an officer of any of FNF, THL or us will belong to us only if that opportunity is expressly offered to that person in that person's capacity as one of our officers.
        Notwithstanding these provisions, our amended and restated certificate of incorporation does not prohibit us from pursuing any corporate opportunity of which we become aware.
        These provisions in our amended and restated certificate of incorporation will no longer be effective on the date that none of our directors or officers are also directors or officers of FNF or THL.
 Amendment to Amended and Restated Bylaws and Amended and Restated Certificate of Incorporation
        Our amended and restated certificate of incorporation and our amended and restated bylaws provide that, subject to the affirmative vote of the holders of any series of preferred stock required by law, the provisions (i) of our amended and restated bylaws may be adopted, amended or repealed if approved by a majority of the board of directors then in office or approved by holders of the common stock and (ii) of our amended and restated certificate of incorporation may be adopted, amended or repealed as provided by the DGCL.
 Listing
        Our common stock is listed on the NYSE under the symbol "BKI".
 Transfer Agent and Registrar
        The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust.

 SELLING SHAREHOLDERS
        Information regarding the beneficial ownership of our common stock by the selling shareholders, the number of shares being offered by the selling shareholders and the number of shares beneficially owned by the selling shareholders after the applicable offering will be set forth in a prospectus supplement, free writing prospectus, post-effective amendment or filings we make with the SEC under the Exchange Act that are incorporated by reference.

•
at a fixed price or prices, which may be changed; 

•
at market prices prevailing at the time of sale; 

•

•
at negotiated prices.
 General
        Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Any selling shareholders, underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be "underwriters" as defined in the Securities Act. Any discounts or commissions they receive from the selling shareholders and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.
        The selling shareholders and other persons participating in the sale or distribution of the securities will be subject to the applicable provisions of the Exchange Act, and the rules and regulations thereunder, including Regulation M. This regulation may limit the timing of purchases and sales of any of the securities by the selling shareholders, or any other person. The anti-manipulation rules under the Securities Act may apply to sales of securities in the market and to the activities of the selling shareholders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution for a period of up to five business days before the distribution. These restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.
        The selling shareholders are not restricted as to the price or prices at which the securities may be sold. Sales of such securities may have an adverse effect on the market price of the securities.
        Moreover, it is possible that a significant number of shares of common stock could be sold at the same time, which may have an adverse effect on the market price of the securities.
        We cannot assure you that the selling shareholders will sell all or any portion of the securities offered hereby.
 Underwriters and Agents
        If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market price or
14

Table of Contents
at negotiated prices. The selling shareholders may offer the securities to the public through an underwriting syndicate or through a single underwriter. The underwriters in any particular offering will be mentioned in the applicable prospectus supplement or pricing supplement, as the case may be.
        Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that the selling shareholders will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.
        The selling shareholders may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. The selling shareholders may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for the selling shareholders. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be will identify any remarketing firm and will describe the terms of its agreement, if any, with the selling shareholders and its compensation.
        In connection with offerings made through underwriters or agents, the selling shareholders may enter into agreements with such underwriters or agents pursuant to which the selling shareholders receive outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received by the selling shareholders under these arrangements to close out any related open borrowings of securities.
 Dealers
        The selling shareholders may sell the offered securities to dealers as principals. The selling shareholders may negotiate and pay dealers' commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with the selling shareholders, at the time of resale. Dealers engaged by the selling shareholders may allow other dealers to participate in resales.
 Direct Sales
        The selling shareholders may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved.
 Institutional Purchasers
        The selling shareholders may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or pricing supplement, as the case may be, will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.
        The selling shareholders will enter into such delayed contracts only with institutional purchasers that the selling shareholders approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

Table of Contents
 Indemnification; Other Relationships
        The selling shareholders may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for the selling shareholders in the ordinary course of business. This includes commercial banking and investment banking transactions.
 Market-Making, Stabilization and Other Transactions
        In connection with any offering of common stock, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.
        In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.
