ADVANCED ENERGY INDUSTRIES REPORTS THIRD QUARTER RESULTS
FOR 1997

FORT COLLINS, CO -- OCTOBER 13, 1997 -- Advanced Energy Industries, Inc. (Nasdaq:AEIS) reported improved revenues and net income for the third quarter of 1997. Net sales grew 97% from a year ago, while net income increased despite the Company's reporting of one-time charges totaling $6.1 million.

For the quarter ended September 30, 1997, Advanced Energy reported net sales of $42.6 million, a 97% improvement over net sales reported a year ago, and a 30% improvement over net sales in the second quarter of 1997 of $32.7 million. Gross margin increased to 40% for the third quarter of 1997, compared with 30.5% a year ago and 38.4% in the second quarter of 1997.

Net income for the third quarter of 1997 was $517,000, or two cents per share, compared with net income of $123,000, or a penny per share, a year ago. Weighted average shares outstanding for the third quarters of 1997 and 1996 were 22,402,000 and 21,622,000, respectively.

The 1997 third quarter improvement in net income was reported despite an increase in operating expenses from one-time charges totaling $6.1 million. These charges included a $3.0 million charge taken for storm damage during heavy rains in the Fort Collins area

on July 29, 1997, and a $3.1 million charge for purchased in-process research and development efforts of Tower Electronics expensed immediately upon the acquisition of Tower Electronics.

Operating income for the third quarter of 1997, excluding the one-time charges, would have been $8.7 million compared with $109,000 in the comparable period in 1996 and $5.0 million in the second quarter of 1997. Net income for the quarter, excluding the one-time charges, would have been $5.5 million, or 24 cents per share.

The 81% tax provision in the third quarter of 1997 exceeds the normal tax provision for the Company because certain of the charges are not tax deductible.

NINE-MONTH RESULTS
For the nine months of 1997, Advanced Energy reported net sales of $95.9 million, a 22% increase over the comparable period. Net income, including the storm damage and purchased in-process R&D, was $4.6 million, or 21 cents per share, compared with net income of $4.5 million, or 21 cents per share, a year ago. Without the one-time charges, net income for the nine months of 1997 would have been $9.5 million or 43 cents per share.

Advanced Energy ended the third quarter of 1997 with $9.3 million of cash, $42.4 million of working capital, $87.4 million of total assets, and $51.9 million of stockholders' equity. Long-term debt increased to $14.7 million primarily due to the debt incurred in connection with the acquisition of Tower Electronics.
