FORT COLLINS, Colo., Nov. 15, 2012—Advanced Energy Industries, Inc. (Nasdaq:AEIS) today announced that it has acquired Solvix SA, a privately held company based in Villaz-Saint-Pierre, Switzerland. A manufacturer of power supplies for the surface treatment and thin films industry, Solvix brings plasma-based sputtering and cathodic arc deposition applications to AE's existing product portfolio. With its best-in-class arc detection and suppression technology, Solvix's product line will enhance AE's offerings in low power and pulsed DC products, allowing it to expand into new applications and serve a broader worldwide customer base. With the addition of Solvix's engineering site in Villaz-Saint-Pierre, AE will also establish a European engineering and development center for its thin-film industrial products business, in keeping with its strategy to move closer to its customers.

"This acquisition is an important step in our Thin Films growth strategy to expand beyond our traditional applications," said Yuval Wasserman, president of AE Thin Films. "Focusing on decorative and hard coating solutions, Solvix will join our Thin Films Industrial organization, complementing our existing product line with its technologically differentiated products. We believe this will strengthen Advanced Energy's competitive position worldwide, offering our customers a comprehensive DC power suite, while expanding our technology base to provide improved performance and address future thin-film deposition needs."
