Gross Margin Increases to 43.7%, Cash Increases $22.7 Million Sequentially

FORT COLLINS, Colo., Oct. 25—Advanced Energy Industries, Inc. (Nasdaq: AEIS) today announced financial results for the third quarter ended September 30, 2006. Sales were $107.7 million for the third quarter of 2006, up 3.0% compared to $104.6 million for the second quarter of 2006, and up 36.7% compared to $78.8 million for the third quarter of 2005. Gross profit was $47.0 million, or 43.7% of sales, compared to $44.8 million, or 42.8% of sales, in the second quarter of 2006, and $28.9 million, or 36.7% of sales in the third quarter of 2005.

Third quarter 2006 income from operations was $18.3 million or 17.0% of sales, compared to $19.2 million, or 18.4% of sales, in the second quarter of 2006. This compares to third quarter 2005 income from operations of $2.2 million, or 2.8% of sales. Third quarter 2005 income from operations includes a $3.0 million litigation settlement expense.

Third quarter 2006 net income was $17.0 million, or $0.38 per diluted share, compared to $18.2 million, or $0.40 per diluted share, in the second quarter of 2006, and compared to a net loss of $3.9 million, or a net loss of $0.10 per share in the third quarter of 2005.

Dr. Hans Betz, president and chief executive officer of Advanced Energy, said, "Sales continued at record levels in the third quarter, driven by continued strength in sales to semiconductor and advanced products customers. Within the advanced products category, sales to solar panel customers increased 42% sequentially as our strategy to grow our presence in this market continues to progress. Our operational focus drove additional efficiency gains, highlighted by a 90 basis point sequential improvement in gross margin. Cash increased by $22.7 million in the third quarter."

Dr. Betz continued, "As you have seen from our guidance, following four quarters of increasing sales to the semiconductor industry, we expect semiconductor levels to decrease modestly in the fourth quarter as semiconductor manufacturers carefully manage inventory levels. We expect growing demand in our emerging markets, such as solar and architectural glass, as these markets continue their capital investment cycle to adopt leading edge technology. We will leverage the strength of our financial model, combined with technology innovation and optimized global operations, to pursue an expanding set of opportunities within core and emerging markets."

Fourth Quarter 2006 Guidance

The Company anticipates fourth quarter sales in the range of $101 million to $105 million, and earnings per share in the range of $0.33 to $0.36.
