Firm Chugs Along with 10 Acquisitions Year to Date

(March 6, 2007) | The Riverside Company has kept up an aggressive acquisition schedule and has closed another deal, racking up the firm's 10th acquisition of 2007. The most recent acquisition, Dapco, is an add-on to Nordco, a leading designer and provider of railroad maintenance-of-way ("MOW") equipment, rebuilding services and repair parts that Riverside acquired in July 2003.

The Dapco add-on has two product lines: Dapco Technologies, LLC ("Rail Services"), which owns and operates ultrasonic rail inspection vehicles, and Dapco Industries ("Industries"), which specializes in the design and manufacture of customized, turnkey computerized inspection systems. Dapco expands Nordco's capabilities in the rail inspection services market and strengthens its market position and product offering. The company is the second add-on to the Nordco platform; in September 2006, Riverside acquired J.E.R. Overhaul, which repairs and rebuilds a wide variety of used MOW equipment. With the acquisition of Dapco, Nordco further diversifies its rail service offering for the "Class 1" railroads.

Dapco, founded in the early 1970s, went on to develop a fleet of rail inspection vehicles designed and customized to leverage the opportunity that broke a 35-year monopoly, presented by federally-mandated railroad inspections. Industries develops customized software and hardware used in railway wheel inspection systems, steel mills as well as industrial high-pressure cylinder inspections. The rail inspection vehicles apply GPS and AI to identify, classify and document rail defects. Rail inspection is mandated by governmental regulations; the individual railroads determine the frequency of tests based on a variety of factors including millions of gross tons traversing the track.

"Nordco is a classic example of how Riverside buys and builds small companies," said Tim Gosline, Riverside Partner. "Working closely with management, we've undertaken a number of initiatives - strategic planning, lean manufacturing, and identifying strong add-on candidates - that have together created a terrific platform. We're very excited by how well Nordco integrates add-ons and by the opportunities created by these purchases."

"Dapco enables us to take advantage of the favorable trends of increasing rail traffic volume and heavier axel loads over less track, which have forced increased MOW spending," explained Bruce Boczkiewicz, Nordco Chief Executive Officer.

Working with Gosline on the transactions were Chip Walker, Riverside Vice President; Karim Botros, Riverside Senior Associate; and Brian Finkelstein, Riverside Analyst. Merrill Lynch Capital and M&I Marshall & Ilsley Bank provided financing for the acquisition.
