Quad-C Management, a middle market private equity firm, completed the acquisition of Vortex, a global provider of trenchless infrastructure rehabilitation products and services, from Platform Partners, a private investment firm, for $160m. “Quad-C is very excited to add Vortex to its portfolio. Mike and his management team have done an incredible job of building a profitable company in an extremely competitive environment, with a sustainable growth model. We believe Vortex will be a great fit for Quad-C, as we are very focused on the specialty products and services sectors and we have a long history of successfully partnering with privately held, entrepreneurial minded businesses,” Tom Hickey, Quad-C Partner.
