"In 1998, Generac sold its portable products division to a private equity group, who later sold it to Briggs & Stratton Corporation. Upon expiration of a non-compete agreement related to the sale, Generac re-entered the portable generator market in 2008, re-establishing its historic leadership in that category. In late 2006, Generac was sold to CCMP Capital, New York, N.Y.
In 2009 CCMP took a write-off, described as a non-cash goodwill and trade name impairment charge, of $583.5 million against their purchase of Generac.[2]
Aaron Jagdfeld was appointed president and chief executive officer of Generac Power Systems in 2008. Through his leadership, the company refocused its vision and branding strategy. Jagdfeld also marshaled the company’s resources to quickly re-enter the portable generator market."
