Pfizer Inc’s $68 billion deal to buy Wyeth gave boutique investment banking firm Evercore Partners a huge jump in the rankings of merger advisers, while Lazard Ltd got left on the sidelines.

One mega-deal was enough to catapult Evercore, which advised Wyeth along with Morgan Stanley, into the list of Top 10 advisers. Evercore now stands at No. 7 for the global and U.S. rankings, up from No. 24 and No. 16 in 2008, according to data from Thomson Reuters.

Morgan Stanley stands at No. 2 globally with 15 deals, and No. 3 in the United States with 10 deals, according to Thomson Reuters.

Pfizer had an army of advisers that included Bank of America, Merrill Lynch, Goldman Sachs, JP Morgan, Barclays and Citigroup. Bank of America Merrill Lynch leads the global league tables, while Barclays Capital leads in the United States, according to Thomson Reuters.

One name missing from today’s news was Lazard, which has been Pfizer’s most active adviser going back to the early 1990s, according Thomson Reuters.

Lazard has advised Pfizer on 15 deals, including its $89 billion purchase of Warner-Lambert Co  in 1999 and $61 billion acquisition of Pharmacia Corp in 2002, the data showed.

Lazard did not immediately return calls seeking comment.
