Former Treasury chief nixed BlackRock offer

Sorry, Larry Fink.

Former Treasury Secretary Tim Geithner passed up a chance to work at mega-fund manager BlackRock, according to sources.

Geithner, who has landed a plum private-equity gig with Warburg Pincus, opted against joining CEO Fink’s BlackRock — with $4 trillion in assets under management — because he wanted to have a more involved role with any company he ended up joining.

“I don’t think [Geithner] wanted to be someone’s arm candy,” said one source familiar with the situation.

Sources said Geithner appreciated the fact that Warburg’s top officials consisted of “talented guys with no big egos.”

Geithner is set to join Warburg in March, where he will be president and managing director.

One industry player says the former Obama appointee, who helped engineer the market’s response to the 2008 financial crisis, thinks he has room to grow at Warburg.

“Warburg Pincus has an excellent record of performance, a very compelling global strategy and an ethical reputation of the highest regard,” Geithner has commented publicly.
