Item 1.01.    Entry into a Material Definitive Agreement.

        On June 8, 2017, Black Knight Financial Services, Inc. (NYSE: BKFS) ("Black Knight" or the "Company") entered into formal agreements for a transaction with Fidelity National Financial, Inc. (NYSE: FNF) ("FNF"), which will result in the distribution of all of the shares of Class B common stock of Black Knight and all of the membership interests of Black Knight Financial Services, LLC ("BKFS LLC"), in each case, that are held, directly or indirectly, by FNF to the holders of FNF Group common stock.

        Under the transaction, Black Knight Holdings, Inc. ("BKHI"), an indirect wholly-owned subsidiary of FNF, will contribute all of its shares of Black Knight Class B common stock and BKFS LLC membership interests into a newly-formed subsidiary, New BKH Corp. ("New BKH"), in exchange for all of the shares of New BKH common stock. BKHI will then distribute to FNF all of the shares of New BKH common stock, which FNF will then distribute to FNF Group shareholders. Immediately following the distribution of New BKH common stock to FNF Group shareholders (the "Distribution"), New BKH and Black Knight will each merge in stock-for-stock transactions with two separate, newly-formed subsidiaries of Black Knight Holdco Corp. ("New Black Knight"), which will be a newly-established public holding company for Black Knight. In the mergers, FNF Group shareholders will ultimately receive a total of approximately 83.3 million shares of New Black Knight common stock, or approximately 0.305551 of a share for each share of FNF Group common stock that they own. The remaining holders of Black Knight's common stock (other than New BKH) will receive one share of New Black Knight common stock for each share of Black Knight common stock they own. Black Knight currently has approximately 154.2 million shares, in the aggregate, of Class A and Class B common stock outstanding. FNF currently has approximately 272.7 million shares of FNF Group common stock outstanding and, at the conclusion of the transactions, New Black Knight will have shares outstanding equal in amount to the Black Knight shares outstanding immediately prior to the conclusion of the transactions. The Distribution and mergers are expected to be tax-free to all existing FNF Group and Black Knight shareholders.

        This structure will result in New Black Knight becoming the new public parent of Black Knight. It is anticipated that, immediately following the mergers, New Black Knight will change its name as mutually agreed between FNF and Black Knight and its shares will be listed on the New York Stock Exchange ("NYSE"). Under the organizational documents of New Black Knight, the rights of the holders of the common stock of New Black Knight will be substantially the same as the rights of holders of Black Knight common stock.

The Merger Agreement

        The mergers will be effected pursuant to the Agreement and Plan of Merger dated as of June 8, 2017 (the "Merger Agreement") by and among Black Knight, FNF, New Black Knight, New BKH and the two newly formed subsidiaries of New Black Knight. As described above, the Merger Agreement provides that New BKH will be merged with a wholly-owned subsidiary of New Black Knight and will survive the merger as a subsidiary of New Black Knight, and that immediately thereafter, the Company will be merged into a wholly-owned subsidiary of New Black Knight and will survive the merger as a subsidiary of New Black Knight. In the mergers, all outstanding shares of Black Knight Class A common stock (other than those held by Black Knight) and of New BKH common stock will be converted into the right to receive shares of New Black Knight common stock.

        The Board of Directors of the Company, following receipt of a recommendation of a special committee consisting solely of disinterested members of the Board of Directors of the Company, has (i) determined that the transactions contemplated by the Merger Agreement and the related agreements are fair to, and in the best interests of, the Company and its shareholders (other than New BKH or any of its affiliates, including, for the avoidance of doubt, FNF), (ii) approved and declared

2

advisable the execution, delivery and performance of the Merger Agreement and the related agreements and the consummation of the transactions contemplated therein and (iii) resolved to submit the Merger Agreement to a vote of the holders of shares of Black Knight common stock and recommend approval of the Merger Agreement by the holders of shares of Black Knight common stock.

        The Merger Agreement contains customary representations and warranties made by each of FNF, the Company and New BKH. FNF and the Company have also agreed to various covenants in the Merger Agreement, including, among other things, covenants (i) not to take certain actions prior to the closing of the mergers without the prior consent of the other (not to be unreasonably withheld, delayed or conditioned) and (ii) not to take certain actions that could reasonably be expected to cause the transactions not to be treated as a tax free transaction.

        The consummation of the mergers is subject to a non-waivable condition that the Merger Agreement be adopted by the affirmative vote of the holders of (a) a majority of all outstanding shares of common stock of the Company and (b) a majority of the then-outstanding shares not owned, directly or indirectly, by FNF, any of its subsidiaries (including, without limitation, BKHI, New BKH, New Black Knight, and the two newly formed subsidiaries of New Black Knight), or any officers or directors of FNF or any of its subsidiaries (including, without limitation, BKHI, New BKH, New Black Knight, and the two newly formed subsidiaries of New Black Knight). In addition, the consummation of the mergers is subject to certain other customary closing conditions, including (i) completion of the Distribution, (ii) obtaining required regulatory approvals necessary to complete the mergers, (iii) the absence of any law or order from any court or governmental authority restraining, enjoining or prohibiting the transactions, (iv) receipt of opinions from the tax advisor with respect to the intended tax treatment of the mergers, (v) the New BKH Form S-1 and New Black Knight Form S-4 having become effective under the Securities Act and (vi) the shares of New Black Knight common stock having been approved for listing on the NYSE.

        The Merger Agreement contains certain customary termination rights for both Black Knight and FNF, including, among others, if the transactions are not consummated on or before the nine month anniversary of the execution of the Merger Agreement (subject to 90-day extension if only regulatory conditions remain to be satisfied), if the Black Knight shareholders do not approve the Merger Agreement, or if either Black Knight or FNF has breached its respective representations, warranties, covenants or agreements such that the related closing condition would not be satisfied (subject to a 30-day cure period).
