The AT&T Deal Gives Evercore a Boost

Evercore Partners (EVR), the investment bank led by Roger C. Altman, is climbing the ranks of Wall Street's top advisers on mergers and acquisitions. Its latest coup: helping AT&T (T) on its $39 billion takeover of T-Mobile, announced on Mar. 20—the year's biggest acquisition. The bank also advised optionsXpress (OXPS) on its $1 billion sale to Charles Schwab (SCHW), unveiled the next day. The deals extend a winning streak for Evercore. The firm advised Sanofi-aventis (SNY) on its $20.1 billion purchase of Genzyme (GENZ), announced in February, and worked with Lubrizol (LZ) on its $9 billion sale to Warren Buffett's Berkshire Hathaway (BRK.A) in March.

Altman, a former deputy secretary of the U.S. Treasury, has expanded Evercore, which he founded in New York in 1996, into a more than 600-employee firm. "We are not a small boutique anymore," says Altman, 64.
