Mr Cooper Group Inc fka COOP

[novascotiaSTS]

WMIH is of course not the parent of COOP, WMIH is simply the former name of COOP.

Direct quote from the Annual Report 2019, it could not be more clearly explained:

Mr. Cooper, which was previously known as WMIH Corp. (“WMIH”), is a corporation duly organized and existing under the laws of the State of Delaware since May 11, 2015. On July 31, 2018, Wand Merger Corporation, a wholly-owned subsidiary of WMIH (“Merger Sub”), merged with and into Nationstar Mortgage Holdings Inc. (“Nationstar”), with Nationstar continuing as a wholly-owned subsidiary of WMIH (the “Merger”). Prior to the Merger, WMIH had limited operations other than its reinsurance business that operated in runoff mode and focused on identifying and consummating an accretive acquisition transaction across a broad array of industries, with a primary focus on the financial institutions sector. As a result of the Merger, shares of Nationstar common stock were delisted from the New York Stock Exchange. Following the Merger closing, the combined company traded on NASDAQ under the ticker symbol “WMIH” until October 10, 2018, when WMIH changed its name to “Mr. Cooper Group Inc.” and its ticker symbol to “COOP.”
