On October 1, 2025, pursuant to the previously announced Agreement and Plan of Merger, dated as of March 31, 2025, by and among the Registrant, Rocket Companies, Inc., a Delaware corporation (“Rocket”), Maverick Merger Sub, Inc., a Delaware corporation and direct, wholly owned subsidiary of Rocket (“Maverick Merger Subsidiary”) and Mr. Cooper Group Inc., a Delaware corporation (“Mr. Cooper”), Maverick Merger Subsidiary merged with and into Mr. Cooper, with Mr. Cooper surviving as a direct, wholly owned subsidiary of Rocket (the “Maverick Merger”), and immediately following such Maverick Merger, Mr. Cooper merged with and into the Registrant (the “Forward Merger” and together with the Maverick Merger, the “Mergers”), with the Registrant surviving as a wholly owned subsidiary of Rocket.

As a result of the consummation of the Mergers, the Registrant has terminated all offerings of its securities pursuant to each Registration Statement. In accordance with an undertaking made by the Registrant in each Registration Statement to remove from registration, by means of a post-effective amendment, any securities which remain unsold at the termination of the offering, the Registrant hereby removes and withdraws from registration all securities of the Registrant registered pursuant to the Registration Statements that remain unsold or otherwise unissued as of the date hereof. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities, and the Registrant hereby terminates the effectiveness of each Registration Statement.
