Advanced Energy Reports Third Quarter 2005 Results

Sales Down 12 Percent Year-Over-Year, Gross Margin Higher By 5 Percent as Operational Improvement Continues

FORT COLLINS, Colo., Oct. 19—Advanced Energy Industries, Inc. (Nasdaq: AEIS) today reported financial results for the third quarter ended September 30, 2005.

(Logo: )

For the 2005 third quarter, sales were $82.0 million, down 6.2 percent compared to second quarter 2005 sales of $87.4 million, and down 12.4 percent from third quarter 2004 sales of $93.6 million. Third quarter 2005 gross margin improved to 37.0 percent of sales compared to 36.7 percent of sales in the second quarter of 2005, and 31.8 percent of sales in the third quarter of 2004.

Operating income was $2.5 million for the third quarter of 2005, compared to $5.5 million in the second quarter of 2005, and $1.9 million in the third quarter of 2004. Third quarter 2005 operating income includes a $3.0 million litigation settlement charge.

The net loss for the 2005 third quarter was $3.9 million, or $0.10 per share. Third quarter net loss includes the previously mentioned $3.0 million litigation settlement, $2.1 million related to the early retirement of the convertible debt, and a non-cash charge of $1.1 million related to the write-off of deferred debt issuance costs. The third quarter of 2005 net loss includes a tax provision of $1.6 million on pretax income earned outside of the United States. The company is unable to provide a tax benefit from its U.S. tax-loss carryforwards until it has demonstrated sustained profitability in the United States. Pretax losses were incurred in the third quarter of 2005 in the United States primarily due to the litigation settlement and debt costs detailed above.

Second quarter 2005 net income was $5.9 million, or $0.18 per diluted share. Second quarter 2005 income from continuing operations was $3.3 million, or $0.10 per diluted share. Included in the second quarter 2005 income from continuing operations was an after-tax gain from the sale of certain marketable securities of $1.1 million. The third quarter 2004 net loss was $1.1 million, or $0.03 per share.

Revenue for the nine months ended September 30, 2005 was $255.5 million compared to $306.9 million for the first nine months of 2004. Net income from continuing operations for the 2005 nine-month period was $147,000, or $0.00 per diluted share, compared to net income for the 2004 nine-month period of $10.3 million, or $0.31 per diluted share.

During the third quarter of 2005, the Company completed a public offering of 11.5 million shares. The net proceeds to the Company totaled $105.7 million, which were used toward the redemption of the Company's convertible subordinated notes. The redemption was completed during third quarter of 2005.

Dr. Hans Betz, president and chief executive officer, said, "We were pleased that our operating performance improved despite the lower revenue caused principally by soft demand from the semiconductor equipment customer base. These operational improvements, combined with the recently completed financing and redemption of the convertible debt, have improved our balance sheet as we generated $5.4 million of cash from operations. Our factory in Shenzhen, China is fully operational and we are well positioned for further improvements in capability and capacity.

"Our innovative product portfolio continues to be validated across existing and emerging end markets through additional design wins on an array of technology platforms. We continue to focus on profitable growth opportunities that best leverage our differentiated technology and global infrastructure in the markets we currently serve, and beyond," said Dr. Betz.

"We expect the soft demand environment for semiconductor equipment to continue in the near term. We anticipate fourth quarter 2005 revenue in the $75 million to $80 million range, and earnings per share in the range of $0.05 to $0.07," said Dr. Betz.
