Doug Schatz, chairman and chief executive officer, said, "Our second quarter results were in line with our expectations.

We believe our demand momentum will continue to increase moderately in the near term as we continue to penetrate new and existing markets.

"Advanced Energy is well-positioned to extend our market and technology positions by leveraging our product portfolio in power, flow, plasma and ion sources, and thermal products to solve critical manufacturing issues," said Mr. Schatz. "Our commitment to investment in research and development focused on our four key technology areas strengthens our product offerings and opportunities, providing greater competitive advantage to our customers."

Based on information currently available, the Company expects third quarter revenue to increase 3 to 8 percent, in the $65 million to $68 million range, and expects a loss per share range of $0.11 to $0.13.
