The business operates from three sites, in Paris, Los Angeles and China, allowing it to serve the major French and US original equipment manufacturers. It counts amongst its global customer base Airbus and Boeing and four of the top five US utility companies where it has successfully introduced its products to the electricity distribution network. In 2011, Permaswage began production on a greenfield manufacturing site in China, increasing its exposure to the Asian aerospace market and allowing it to become an integrated local supplier for existing customers that have a manufacturing process there. The business was sold to Precision Castparts Corp. of the US in June 2013 for $600 million. Bridgepoint retained ownership of DMC Power.
