WMI HOLDINGS CORP. ANNOUNCES APPOINTMENT OF NEW INDEPENDENT AUDITOR

COMPANY ISSUES REMINDER REGARDING TRANSFER RESTRICTIONS APPLICABLE TO NEW COMMON STOCK

SEATTLE, April 16, 2012/ – WMI Holdings Corp. (Pink Sheets: WMIH.PK) (the “Company”), formerly Washington Mutual, Inc. announced today that the Audit Committee of the Company’s Board of Directors approved the appointment of Burr Pilger Mayer, Inc. as the Company’s new independent registered public accounting firm, effective as of April 10, 2012, to perform independent audit services for the Company.

Mike Willingham, Chairman of the Board of Directors, stated, “We are pleased to have Burr Pilger Mayer, Inc. engaged as the Company’s new auditors to provide audit services in connection with the audit of the Company’s financial statements. We look forward to working with our new auditors.”

The Company also noted that it has become aware that its new common stock is trading on the pink sheets on an unsolicited quote basis, even though the Company has not taken any steps or actions to list or otherwise facilitate any trading in its common stock. The Company reminds shareholders and investors that it has no control over the trading of its securities on the pink sheets, except for the restrictions on transfers contained in the Company’s Amended and Restated Articles of Incorporation (the “Articles”) and the Company’s Amended and Restated Bylaws (the “Bylaws”).

As previously disclosed, the Company’s Articles and Bylaws impose significant transfer restrictions on the Company’s new common stock. These court-approved transfer restrictions have been adopted in order to protect the Company’s ability to utilize significant net operating loss carry-forwards under and in accordance with regulations promulgated by the Internal Revenue Service. Specifically, among other things, without the consent of the Board, these provisions (a) restrict the ability of a shareholder to acquire or own more than 4.75% of new common stock and (b) restrict the ability of a shareholder to dispose of new common stock if such shareholder owns, as of March 19, 2012, the date the Company emerged from bankruptcy, more than 4.75% of new common stock. The Articles provide that transactions in the Company’s new common stock in violation of these transfer restrictions will be void.

These transfer restrictions are set forth in Article VI of the Articles and Section 9.9 of the Company’s Bylaws. All shareholders and investors are advised to review the restrictions on transfer contained in the Articles and Bylaws. A restricted legend has been placed on certificates representing the Company’s new common stock. You also should consult with your legal, financial and tax advisors with respect to how these transfer restrictions potentially affect your holdings of or investment in new common stock.

As previously disclosed, the new Board of Directors has formed a Corporate Strategy & Development Committee to explore opportunities available to the Company to deploy its assets and enhance shareholder value.
