100 Fastest-Growing rank: 4
Years on the list: 3
LKQ is the leading supplier of recycled auto parts and crash-replacement parts to tens of thousands of auto mechanic shops and car dealerships in the U.S. The Chicago-based company has made our list for three years running by continuing to rev up its national network though acquisitions that help it become a "one-stop shop" for replacement auto parts that include engines, doors, fenders, and refurbished bumpers and wheels.
Since last year, LKQ has snapped up 13 businesses, five of them in the first half of 2010. Three-year annualized revenues have risen 41%, with 29% earnings-per-share growth in that time.
