Dr. Hans Betz, president and chief executive officer of Advanced Energy, said, "Sales to semiconductor, flat panel display and architectural glass customers drove much of the second quarter demand with double-digit sequential growth in all three of these core markets. Unit sales of our Pinnacle DC power conversion system, a long-time market leader for a range of PVD applications in our core markets, reached an all-time record level. The recent announcements of power system orders from three solar panel manufacturers further demonstrate our success in leveraging our product portfolio across core and emerging market opportunities."

Dr. Betz continued, "The results of our second quarter exceeded our target financial performance. We delivered 43 percent incremental operating margins for every revenue dollar above $60 million. These are goals that we've been driving toward for the past twelve months, and I thank Advanced Energy's employees for their major contributions and successful execution of these critical corporate objectives. We continue to focus on further improving our financial performance and expanding our market presence in profitable growth areas."

Third Quarter 2006 Guidance

The Company anticipates third quarter sales in the range of $102 million to $106 million, and earnings per share in the range of $0.34 to $0.37, assuming a 12% effective tax rate.
