After nearly two decades of sustained organic growth,
Joseph Holson led WIL Research through an initial period of private capital-financed expansion. In 2004, Holson and four other senior executives (Mark D. Nemec, Dr. Christopher P. Chengelis, Dr. Daniel W. Sved, and James M. Rudar) initiated a management buyout (in partnership with
private equity firm Behrman Capital) from
Great Lakes Chemical Corporation which led to the formation of a holding company (WRH, Inc.). The expansion continued with the merger of Biotechnics, LLC (
Hillsborough, NC, led by Dr. George Parker) with WIL Research operations in Ashland, the acquisitions of Notox Beheer BV (
's-Hertogenbosch, Netherlands, let by Jan van der Hoeven, Dr. Wilbert Frieling, and Dr. Ilona Enninga) and QS Pharma LLC (
Boothwyn, PA), and the subsequent $500 million sale of WRH, Inc. to American Capital, Ltd. (NASDAQ:ACAS) in 2007. After the sale to ACAS, Holson served as Vice President and
Chief Scientific Officer of the global entity while continuing to serve as President and Director of WIL Research Laboratories in Ashland until his retirement in November 2008. Upon Holson's retirement, Nemec was appointed President and
Chief operating officer of the Ashland flagship facility, and Chengelis was named Vice President and Chief Scientific Officer. Under the ownership of American Capital, David Spaight was named Chairman and CEO of the global holding company in 2010, which undertook a re-branding and global integration effort. During the ACAS-led period, growth of the company occurred primarily through additional acquisitions, including those of Midwest BioResearch, LLC (
Skokie, IL, led by Dr. Michael Schlosser) and Ricerca Bioscience's pharmaceutical services facility in
Lyon, France (led by Stéphane Bulle). In addition, a new safety assessment facility in
Schaijk,
Netherlands (close to the existing
Den Bosch site) was opened in 2015 to augment the European operations. These activities combined to increase the total number of employees in the global entity to more than 1300, with total 2015 revenues of $215 million. The platform WIL Research Laboratories facility in Ashland was subsequently renamed to Charles River Laboratories Ashland, LLC. ==References==
