Of all the high-ranking dealmakers Goldman Sachs has poached from competitors this year, this one is the biggest. In Simon, Goldman gets one of rival JPMorgan's most senior and high-profile investment bankers.
Simon, who joined JPMorgan in 2002, has handled some of his firm's — and the industry's — largest mergers and acquisitions, including: SoftBank's $20 billion buyout of Sprint, Dell's $25 billion take private, and AT&T's $85 billion acquisition of Time Warner.
