Billionaires Tull, Walter Take 5% Stake in Mubadala Capital

The investment firm led by Guggenheim Partners founder Mark Walter and financier Thomas Tull will take a minority stake in Mubadala Investment Co.’s asset management subsidiary, the second time an outside investor has been allowed to own a piece of the Abu Dhabi fund in recent months.

As part of the deal, TWG Global is separately committing $2.5 billion to Mubadala Capital, which, in turn, is anchoring and leading a $10 billion syndicated investment in TWG, according to a statement. That investment is part of TWG’s $15 billion equity raise, the companies said.
