(“GVS”), a family-owned manufacturer of custom liquid vacuum tank (“LVT”) trucks, for a purchase price of approximately $29 million. The purchase price includes the acquisition of GVS’s manufacturing facility for approximately $15 million. 

Founded in 1985 and based in Navasota, Texas, GVS designs and manufactures custom code and non-code liquid vacuum tank (“LVT”) trucks in carbon steel, stainless steel, and aluminum.
