Lamb's departure comes as BearingPoint and other large consulting firms face a weakened services market. Last week, BearingPoint reported that revenue for its fiscal first quarter rose 23% to $747.6 million, but much of that gain was driven by cash generated from acquisitions. Merrill Lynch analyst Stephen McClellan sees prospects for BearingPoint's core consulting business as "lackluster."
BearingPoint says it's searching for a replacement for Lamb.
