Calfee Congratulates Client Industrial Growth Partners on Its Acquisition of Lamart Corporation

Calfee congratulates our client, San Francisco-based private equity investment firm Industrial Growth Partners (IGP), on its recently announced acquisition of Lamart Corporation, a family owned manufacturing company with operations in New Jersey, California and Mexico.

Founded in 1956 by the Hirsch family, Lamart is a manufacturer of engineered, coated and laminated flexible materials serving technically demanding applications in the aerospace and defense, space, automotive, construction, energy, medical, industrial, and optical end markets. The Hirsch family will remain a significant minority shareholder in the Company, and the Company's day-to-day leadership and operations will remain unchanged. The partnership with IGP allows Lamart to invest in the next phase of the Company's growth while preserving its culture, craftsmanship, and customer focus.

Founded in 1997, Industrial Growth Partners has raised more than $3.4 billion in equity capital since its inception. The firm invests exclusively in middle-market companies in the industrial sector in partnership with management teams.

Calfee's Corporate and Finance acquisition team was led by Partner and Firm Vice Chair Terrence F. (Terry) Doyle and included Partner Mitchell L. Griffith, Senior Counsel Erik H. Nielsen, and Associate Attorneys Jacob J. (Jake) Bourquin, Christopher J. (Chris) Brubaker, and Maxwell C. (Max) Herath. The Commercial Finance team was led by Partner Ellen G.
