Advanced Energy Reports Fourth Quarter and Year-End 2005 Results
FORT COLLINS, Colo., Feb. 16-Advanced Energy Industries, Inc. (Nasdaq: AEIS) today reported financial results for the fourth quarter and year ended December 31, 2005.


For the 2005 fourth quarter, sales were $80.4 million, up 2.1 percent compared to $78.8 million in the third quarter of 2005, and down 5.2 percent compared to $84.8 million in the fourth quarter of 2004. Gross profit was $30.2 million, or 37.6 percent of sales for the fourth quarter of 2005, compared to $28.9 million, or 36.7 percent of sales in the third quarter of 2005, and $13.3 million, or 15.7 percent of sales in the fourth quarter of 2004.

Income from continuing operations was $5.0 million, or $0.11 per diluted share, in the fourth quarter of 2005, compared to a loss from continuing operations of $4.2 million, or $0.11 per share, in the third quarter of 2005, and a loss from continuing operations of $23.3 million, or $0.71 per share, in the fourth quarter of 2004. Fourth quarter 2005 income from continuing operations reflects a tax rate of 21 percent, which is lower than the Company's anticipated tax rate of 40 percent due to the mix of foreign and domestic income in the respective taxing jurisdictions, allowing the utilization of the net operating loss carryforwards.

During the fourth quarter 2005, the Company sold its IKOR technology assets, resulting in income from discontinued operations of $5.0 million, or $0.11 per diluted share. Net income from discontinued operations in the third quarter of 2005 was $312,000, or $0.01 per diluted share, and $340,000, or $0.01 per diluted share in the fourth quarter of 2004.

Fourth quarter 2005 net income was $10.0 million, or $0.22 per diluted share, compared to a net loss of $3.9 million, or $0.10 per share in the third quarter of 2005, and a net loss of $23.0 million, or $0.70 per share in the fourth quarter of 2004.

The third quarter 2005 net loss included a $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. Included in the fourth quarter 2004 net loss were $19.8 million in pre-tax charges primarily attributable to increased excess and obsolete inventory reserves, a change in an accounting estimate related to demonstration equipment, employee severance and termination costs, and intangible asset impairments.

Dr. Hans Betz, president and chief executive officer of Advanced Energy, said, "We continue to improve our gross margin even on relatively flat sequential sales volumes," said Dr. Betz. "Incremental operating margin above our $66 million break even level was approximately 44 percent, and we expect additional improvements throughout the year as we continue to benefit from the increasing capability of our worldwide manufacturing operations."

Sales for the 2005 fiscal year were $325.5 million, a 14.5 percent decrease compared to net sales of $380.5 million in fiscal year 2004. Net income for the year was $12.8 million, or $0.34 per diluted share, compared to net loss of $12.7 million, or $0.39 per share in fiscal year 2004. Net income from continuing operations was $3.6 million, or $0.10 per diluted share, in fiscal year 2005, compared to a loss from continuing operations of $14.7 million, or $0.45 per share, in fiscal year 2004.

"We are currently experiencing increased demand for our innovative portfolio of solutions that enable advanced processing," said Dr. Betz. "During the fourth quarter, we made progress in further penetrating emerging opportunities in the solar market with both our DC and RF power platforms, and in flat panel display with our RF technology for a new etch application. We are well-positioned to apply our technology leadership and worldwide manufacturing excellence to a diverse set of high-growth, high-profitability opportunities."

Dr. Betz continued, "Based on improving order trends, we currently expect first quarter 2006 sales to be $88 million to $91 million. We anticipate earnings per share in the $0.17 to $0.19 range, including estimated stock-based compensation expense of $600,000, or $0.01 per diluted share after tax, due to our adoption of SFAS 123(R) in the first quarter of 2006."
