Exhibit 99.2

UNAUDITED PRO FORMA FINANCIAL INFORMATION

On February 15, 2022, Cannae Holdings, Inc. (“Cannae”, the “Company”, “we” or “our”) completed the disposition of its ownership interests in Optimal Blue Holdco, LLC, a Delaware limited liability company (“Optimal Blue”), to Black Knight, Inc., a Delaware corporation (“Black Knight”) and its subsidiaries (the “Optimal Blue Disposition”), pursuant to that certain Purchase Agreement (the “Purchase Agreement”), dated as of February 15, 2022, by and among Black Knight, Cannae, and Optimal Blue, among others. In conjunction with the Optimal Blue Disposition, Cannae received aggregate consideration of (y) $144.5 million in cash and (z) 21.8 million shares of common stock, par value $0.0001 per share (the “DNB Shares”), of Dun & Bradstreet Holdings, Inc., a Delaware corporation (“DNB”). Following the consummation of the Optimal Blue Disposition, Cannae no longer has any ownership interest in the Class A Units of Optimal Blue.

We account for our historical ownership interests in Optimal Blue and DNB under the equity method of accounting and will continue to account for our ownership interests in DNB under the equity method of accounting subsequent to the Optimal Blue Disposition.

The following tables present information about the Company’s financial condition and results of operations, after giving effect to the Optimal Blue Disposition.

The information under ‘‘Summarized Pro Forma Balance Sheet Information’’ in the table below assumes the Optimal Blue Disposition was completed on September 30, 2021.

The information under ‘‘Summarized Pro Forma Statement of Operations Information’’ in the tables below gives effect to the pro forma results for the nine months ended September 30, 2021 and year ended December 31, 2020 assuming the Optimal Blue Disposition occurred on September 15, 2020, the date the Company first acquired its ownership interest in Optimal Blue.

The unaudited pro forma information, while helpful in illustrating the financial characteristics of the Company after the Optimal Blue Disposition, does not necessarily reflect what the Company’s financial condition or results of operations would have been had the investment occurred on the dates indicated. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors including, but not limited to, the impact that our estimated basis in the DNB Shares may have had on our accounting for historical one-time transactions unrelated to the Optimal Blue Disposition under the closing date assumption used herein and the completion of our accounting for our ownership interest in Optimal Blue through the date of the Optimal Blue Disposition in calculating the estimated gain. As a result, unaudited pro forma data is presented for illustrative purposes only and does not represent an attempt to predict or suggest future results.

The information presented below was derived from our consolidated financial statements and should be read together with such consolidated financial statements of Cannae, including the related notes thereto, included in the Company’s Quarterly Report on Form 10-Q for the period ended September 30, 2021 and Annual Report on Form 10-K for the year ended December 31, 2020.
