The disclosure provided below in Item 8.01 with respect to the RRA Amendment (as defined below) is incorporated by reference into this Item 1.01.

On January 5, 2018, WMIH Corp. (the “Company”) issued a press release announcing the effectiveness of the Charter Amendment and the modification of the terms of its Series B Convertible Preferred Stock, par value $0.00001 per share (the “Series B Preferred Stock”), which is filed as Exhibit 99.1.

As previously disclosed on December 11, 2017, the requisite holders (the “Series B Holders”) of the Company’s Series B Preferred Stock approved an amendment which was filed with the Delaware Secretary of State on December 7, 2017 (the “Charter Amendment”) to the Company’s Amended and Restated Certificate of Incorporation (the “Existing Charter”), which Charter Amendment amends the terms of the Series B Preferred Stock and effects an exchange of the previously outstanding 3.00% Series B Preferred Stock for shares of 5.00% Series B Preferred Stock. The Charter Amendment became automatically effective at 12:00 a.m., New York City time, on January 5, 2018, given that no Qualified Acquisition (as defined in the Existing Charter) had occurred prior to such time. In connection with the effectiveness of the Charter Amendment, the Company entered into an amendment on January 5, 2018 (the “RRA Amendment”) to its Registration Rights Agreement, dated January 5, 2015, among the Company, Citigroup Global Markets Inc., and KKR Capital Markets LLC, which is an affiliate of KKR Fund Holdings L.P. and KKR Wand Investors L.P.

A copy of the Charter Amendment was filed as Exhibit 3.1 to the Company’s Current Report on Form 8-K filed with the Commission on December 11, 2017. A copy of the RRA Amendment is filed herewith as Exhibit 10.1.
