Advent International has completed the acquisition of aluminum profile manufacturer Corialis from Sagard and Ergon. UBS, Rabobank and Jefferies are reported to have lined up a covenant-lite loan of up to €414 million to support the deal. The company supplies profile systems to small- and medium-sized window, door and conservatory fabricators for both the new-build and renovation construction markets. It distributes its products in over 20 countries, generating revenues of around €350 million in the 12 months to September 2014. Ergon and Sagard had owned Corialis for close to eight years.
