On December 9, 2013, WMI Holdings Corp. (the “Company”) issued a press release announcing its entry into a conditional commitment letter, dated December 8, 2013 (the “Commitment Letter”), with KKR & Co. L.P. (“KKR”). Subject to the completion of definitive documentation, due diligence and the terms and conditions of the Commitment Letter, KKR has agreed (i) to purchase approximately $10.55 million face amount of convertible preferred stock of the Company at a price per share of $1.10 convertible on a one-for-one basis into shares of common stock of the Company (the “Convertible Preferred Stock”), and (ii) to commit to purchase up to $150 million aggregate principal amount of subordinated 7.5% PIK notes, which may be issued in one or more tranches over a three year period, each with a seven year term from the date of initial issuance (the “Subordinated Notes”), subject to certain terms and conditions. Substantially all of the proceeds from the Subordinated Notes, if and when issued, would be used by the Company to fund future acquisitions. Upon consummation of the transactions contemplated by the Commitment Letter, KKR would receive five-year warrants to purchase approximately 61.4 million shares of the Company’s common stock, 30.7 million of which would have an exercise price of $1.32 per share and 30.7 million of which would have an exercise price of $1.43 per share. KKR would also have the right for three years to participate up to 50% in equity offerings up to an aggregate of $1 billion by the Company subject to certain limitations, including a cap in ownership by KKR (and its affiliates) of 42.5% of the Company’s common equity. The Convertible Preferred Stock, if and when issued, will include the right for KKR to appoint one of seven members to the board of directors of the Company. The Commitment Letter terminates on January 31, 2014 in the event that the parties do not enter into definitive documentation on or before such date. The Company has agreed to reimburse KKR for certain expenses incurred by it in connection with the Commitment Letter and has also agreed to pay KKR a termination fee equal to $2 million in certain circumstances.

A copy of the press release is furnished as part of this report as Exhibit 99.1 and is incorporated by reference herein.

All statements other than statements of historical fact included in this report that address activities, events, conditions or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business and these statements are not guarantees of future performance. These statements can be identified by the fact that they do not relate strictly to historical or current facts.

Such forward-looking statements involve risks and uncertainties that may cause actual events, results or performance to differ materially from those indicated by such statements. These risks are identified and discussed in the Company’s Form 10-K for the year ended December 31, 2012 under Risk Factors in Part I, Item 1A. These risk factors will be important to consider in determining future results and should be reviewed in their entirety. These forward-looking statements are expressed in good faith and we believe there is a reasonable basis for them.
