Proto Labs is no Facebook.
But the Internet-enabled, quick-turn manufacturer of custom parts for prototyping and short production runs is Minnesota's leading candidate to go public this quarter, as the market strengthens and the capital-raising pipeline warms.
On Feb. 1, Proto Labs filed what could be the last update to its offering documents with the Securities and Exchange Commission. The company hopes to raise about $100 million-plus in its initial public stock offering. That would be the largest Minnesota IPO since the Great Recession of 2008.
Proto Labs increased earnings by 63 percent in 2011 to $18 million on revenue that rose 52 percent to $99 million, a record year for the private company.
The Maple Plain-based outfit has doubled employment to 511 since 2008 and sold product in more than 50 countries. Proto Labs, founded by Minnesota technologist Larry Lukis, also has acquired a 128,000-square-foot office and manufacturing facility in Rosemount for $4 million, on top of its three-building, 170,000-square-foot campus in Maple Plain, a half hour west of Minneapolis.
The company's shareholders include North Bridge Growth Equity (32 percent), Lukis (36 percent) and 10-year CEO Brad Cleveland (8 percent).
THORBURN LANDS PENNEYS
Designer Bill Thorburn left the old Dayton Hudson Department Stores in 1994 to launch his own company, first in his living room and, for the past 15 years or so, in the warehouse district, where he employs about 15 at the Thorburn Group.
Dayton Hudson Corp. eventually jettisoned its once-cornerstone department stores to focus on Target's expansion. Now Thorburn has just landed some business from a department store company -- J.C. Penney, whose new president is Michael Francis, the former Target marketing boss and longtime Thorburn acquaintance.
