100 Fastest-growing companies

Bucyrus International makes giant shovels and other equipment for mining coal, copper, iron ore and other minerals. With more than 70% of sales for projects outside the U.S., the Milwaukee-based company kept revenues growing last year amid low commodities prices and tough credit conditions.

In February, the firm finalized its purchase of Terex Corp.'s surface-mining equipment business, which expanded Bucyrus's product line and Asian presence. Acquisition costs took a bite out of earnings for the most recent quarter, but the deal also led to a 30% increase in the company's order backlog for the first half of the year.--D.M.
