Advanced Energy Announces Record Bookings and Revenues for the Second Quarter 2010

FORT COLLINS, Colo., July 21, 2010—Advanced Energy Industries, Inc. (Nasdaq GM: AEIS) today announced financial results for the second quarter ended June 30, 2010. Total sales for the second quarter were $115.2 million, representing an all-time high for the company in a single quarter and producing earnings of $0.31 per diluted share. The results highlighted in this release include our Aera® mass flow controller business that is currently being divested, as well as the inclusion of two months of operating results from PV Powered.

“We had an outstanding second quarter, with $154 million in bookings and $115 million in revenue, including PV Powered and the flow business. As our semiconductor revenues continued to grow, the semiconductor industry demonstrated its momentum again this quarter,” said Dr. Hans Betz, chief executive officer.

"Our recent acquisition of PV Powered contributed significantly to our higher inverter revenues and backlog, which we anticipate will provide momentum for the second half of 2010. PV Powered also contributed to our bottom line, delivering a profitable second quarter ahead of expectations and making the acquisition immediately accretive. The addition of this excellent team and product line to our Solaron inverter business positions us to forge ahead and take the leading position in the US market for inverters and expand worldwide.”

"Additionally, today we announced that we are divesting our flow business. We see this move as a crucial part of our corporate strategy to focus the company on becoming the market leader in power conversion and capitalize on future growth opportunities.”

Semiconductor sales rose 9.9% sequentially to $53.5 million, representing 46.4% of total sales for the quarter. Sales to the non-semiconductor thin film markets increased 87.2% sequentially to $35.9 million, representing 31.2% of total sales for the quarter. Inverter sales grew substantially with the addition of PV Powered to $14.4 million to 12.5% of total sales compared to $2.3 million in the first quarter. Service revenue was flat sequentially at $11.4 million, representing 9.9% of total sales for the quarter.

Bookings for the second quarter, including $15.3 million for the mass flow controller business, hit a record of $154.3 million, or a 60.0% increase, compared to $96.7 million in the first quarter of 2010, resulting in a book-to-bill ratio of 1.34:1 for the second quarter. Ending backlog for the second quarter increased 52.0% sequentially to $123.6 million, including $14.4 million for the flow business, compared to $81.3 million at the end of the first quarter of 2010.

Advanced Energy also announced that it has entered into an agreement to sell its flow business, related product lines and all related assets including the real property in Japan to Hitachi Metals, Ltd. for $44 million in cash, subject to an adjustment based on inventory balance at closing. The company anticipates this transaction will close in the third quarter of 2010 subject to satisfaction of customary closing conditions.

As a result of this transaction, the financial results for our flow business will be recorded in discontinued operations on a net basis beginning with the second quarter 2010. These amounts are revenue of $15.1 million, gross profit of $5.3 million, operating expenses of $1.7 million and net income of $2.2 million, or $0.05 per diluted share in the quarter ended June 30, 2010. Comparable results for the flow business for the second quarter of 2009 were revenues of $3.7 million, gross profit of $0.6 million, operating expenses of $1.3 million and a net loss of $0.4 million, or $0.01 per diluted share. For comparative purposes, the financial results discussed below assume the adjustments for the divestiture have been made.

Excluding the flow business, sales for the second quarter of 2010 increased 43.6% to $100.1 million from $69.7 million in the first quarter of 2010, and up substantially from $31.9 million in the second quarter of 2009.

Gross margin for the second quarter was 44.5%, compared with 41.9% in the first quarter of 2010, as a result of higher revenues and leverage from overhead absorption. This compares to gross margin of 22.8% in the same period last year.

Operating expenses for the second quarter increased to $31.5 million. This increase was significantly driven by the addition of approximately two months of operating costs associated with the acquisition of PV Powered, including an additional $767,000 of amortization of acquired intangible assets.

Second quarter net income from continuing operations was $11.5 million or $0.26 per diluted share, compared to net income from continuing operations of $4.9 million or $0.11 per diluted share in the first quarter of 2010. In the same period a year ago, net loss from continuing operations was $16.0 million or a loss of $0.38 per share.

Cash, cash equivalents and investments were $128.9 million at the end of the second quarter, versus $163.4 million in the first quarter reflecting the $35 million payment for the PV Powered acquisition.

Third Quarter 2010 Guidance
The Company anticipates third quarter 2010 results from continuing operations, without revenues from the flow business, to be within the following ranges:
• Sales of $130.0 million to $140.0 million
• Earnings per share of $0.36 to $0.44

Advanced Energy Announces Agreement to Sell Aera Mass Flow Controller and Related Product Lines to Hitachi Metals, Ltd.

FORT COLLINS, Colo., July 21, 2010—Advanced Energy Industries, Inc. (Nasdaq GM: AEIS) (the “Company” or “Advanced Energy”) today announced that the Company has entered into an agreement to sell its Aera^® mass flow control and related product lines and real property in Japan to Hitachi Metals, Ltd., part of Hitachi Metals Group, for $44 million in cash, subject to adjustment based on the inventory balance at closing. Subject to the satisfaction of customary closing conditions, the Company anticipates the closing of this transaction within the third quarter of 2010.

"The sale of our Aera mass flow controller product line represents a significant step in our strategy to focus our global resources on power conversion,” said Dr. Hans Betz, Chief Executive Officer of Advanced Energy. “Our core technology portfolio in power conversion for the semiconductor, flat panel display, solar panel and other thin film markets as well as grid-tied PV inverters is the foundation of our long-term growth strategy. These markets provide tremendous growth opportunities as we continue to develop technologies and scale our business to address them.”

At closing, the Company will transfer substantially all of the assets associated with the Aera product lines to Hitachi Metals, Ltd., which will assume certain related liabilities as well as global sales for the Aera product lines. During a transition period, the Company has agreed to provide manufacturing support and certain other services to enable Hitachi Metals, Ltd. to complete the transition without interruption in business flow. Both companies will work to maintain the highest quality service and support throughout the transition for customers using the Aera flow products. It is also contemplated that Hitachi Metals, Ltd. will leverage the Company’s worldwide service infrastructure and have the Company become an authorized service provider for Hitachi Metals, Ltd. to service products in all countries other than Japan.

“Hitachi Metals, Ltd. is a highly capable materials manufacturer, and the Aera product lines are complementary to their current business. We are working together to ensure a seamless transition for our mass flow control customers worldwide,” continued Dr. Betz.

“We are very pleased to add the high-quality Aera product line to our product portfolio,” said Mr. Hiroyuki Fujii, Executive President of Hitachi Metals, Ltd. “This acquisition increases our industry presence in these strategic markets. Advanced Energy has built a great reputation in the semiconductor, flat panel display and solar panel market, and it is our honor to acquire these products and carry forward the strong heritage of the Aera product line.”

The Aera product lines had sales of $11.9 million in the first quarter of 2010 and $15.1 million in the second quarter of 2010. As a result of the sale, the Company's assets are classified as held for sale on the balance sheet as of June 30, 2010, and results from continuing operations will be reduced by the revenue and costs associated with the mass flow controller business and will be included in the discontinued operations line on the income statement.

Advanced Energy's First Quarter 2010 Results Fueled by Strong Semiconductor Growth

Fort Collins, Colo., April 22, 2010 – Advanced Energy Industries, Inc. (Nasdaq GM: AEIS) today announced financial results for the first quarter ended March 31, 2010.

Sales for the first quarter of 2010 increased 22.7% to $81.6 million from $66.4 million in the fourth quarter of 2009, and increased 150.0% from $32.6 million in the first quarter of 2009.

Sales were robust in the first quarter driven by strong growth in the semiconductor market. Semiconductor sales rose 47.7% sequentially to $48.6 million, representing 59.6% of total sales for the quarter. Sales to the non-semiconductor markets increased 3.9% sequentially to $21.5 million, representing 26.3% of total sales for the quarter. Service revenue was flat sequentially at $11.5 million, representing 14.1% of total sales for the quarter.

Bookings for the first quarter were $96.7 million compared to $98.0 million in the fourth quarter of 2009, resulting in a book to bill ratio of 1.19:1 for the first quarter. Ending backlog increased 22.8% sequentially to $81.3 million at the end of the first quarter compared to $66.2 million at the end of the fourth quarter of 2009.

Gross margin improved significantly to 40.6% in the first quarter, up from 36.8% in the fourth quarter of 2009, as a result of greater efficiencies and improved operating leverage due to higher revenues. This compares to 19.6% in the same period last year.

Operating expenses rose 11.0% sequentially to $25.0 million as we eliminated our temporary cost reductions related to pay cuts and shutdowns. In addition, expenses associated with the pending acquisition of PV Powered were $325,000 ($0.01 per share).

First quarter net income was $6.2 million or $0.15 per diluted share, compared to net income of $1.5 million or $0.04 per diluted share in the fourth quarter of 2009. In the same period a year ago, net loss was $79.8 million or a loss of $1.90 per share due primarily to a non-cash goodwill impairment charge of $63.3 million or $1.51 per share. Cash, cash equivalents and investments were $163.4 million at the end of the first quarter, a decrease of $14.1 million from the fourth quarter due to increases in accounts receivable and inventory to support the growth in revenues.

“Marked by the third consecutive quarter of greater than 20% total revenue growth, we were extremely pleased with our first quarter results. Momentum in the semiconductor capital equipment market drove the majority of the growth this quarter continuing the three-quarter trend of over 40% expansion in that market,” said Dr. Hans Betz, chief executive officer. “Advanced Energy once again distinguished itself as one of the premier suppliers as we successfully managed through supply chain constraints in order to meet aggressive customer demand.”

“In keeping with our strategy to increase Advanced Energy’s presence in the renewable energy market, we announced a definitive agreement to acquire PV Powered, a leading manufacturer of grid-tied PV inverters serving the commercial and residential markets. The combined company will offer a complete suite of products, propelling Advanced Energy forward as a leader in the North American solar inverter market.”

On March 24, 2010, Advanced Energy announced a definitive agreement to acquire 100% of the outstanding shares of PV Powered. Pending review under the Hart-Scott Rodino Act, we expect the acquisition to close in early May. We will provide updated guidance once the acquisition is complete.

Second Quarter 2010 Guidance

The Company anticipates second quarter 2010 results to be within the following ranges:

• Sales of $92 million to $102 million
• Earnings per share of $0.21 to $0.31

Advanced Energy Announces Acquisition of Solar Inverter Provider, PV Powered

Fort Collins, Colo., March 24, 2010 – Advanced Energy Industries, Inc. (Nasdaq GM: AEIS) today announced it has signed a definitive agreement to acquire PV Powered Inc., a leading manufacturer of grid-tied PV inverters in the residential, commercial, and utility-scale markets. The acquisition is expected to add an estimated $40-50 million to Advanced Energy’s 2010 revenues and be neutral to marginally dilutive to GAAP net income in 2010.

“We are very excited to announce this acquisition and believe the combination of Advanced Energy and PV Powered will continue our strong momentum in the inverter market, propelling us forward as a leading manufacturer of solar inverters in North America. The addition of PV Powered’s transformer-based inverters with power levels below 500kw for the small to mid range commercial inverter market allows Advanced Energy to target a portion of the market that we have not yet addressed. As a combined company, our comprehensive portfolio of both transformerless and transformer-based inverter products will serve the entire spectrum of commercial project sizes from 30kw to multi-megawatt utility installations, placing us firmly at the heart of the emerging and fast-growing solar inverter market,” said Hans Betz, chief executive officer of Advanced Energy.

PV Powered is an innovation leader for high-reliability transformer-based PV inverters utilized in commercial roof top and ground mount systems in the North American market. Founded in 2003 and based in Bend, Oregon, PV Powered is a privately held company with approximately 90 employees and $21 million of revenues in 2009. Its inverters range in size from 30kw to 260kw for the commercial market and 1kw to 5kw for the residential market, with market leading efficiency ratings. PV Powered’s experienced inverter engineering team has continuously optimized the performance and reliability of its inverters allowing PV Powered to offer the industry’s first standard 10 year product warranty and optional 20 year extended warranty.

"The employees and management of PV Powered are extremely excited at the prospect of joining Advanced Energy,” said Gregg Patterson, chief executive officer of PV Powered. “PV Powered and Advanced Energy have a collective history of industry innovation, driven by a commitment to power conversion efficiency and inverter reliability that leads the market. Both organizations share a common mission to deliver the lowest levelized cost of energy and the highest levels of customer satisfaction. Together, we can offer the broadest technology and product portfolio in the industry.”

Under the agreement, Advanced Energy will acquire PV Powered for a purchase price of up to $90 million consisting of $50 million to be paid at closing in the form of $35 million in cash and $15 million in Advanced Energy’s common stock, as well as up to $40 million in a potential earn-out based on PV Powered’s full year 2010 financial results. The transaction will be subject to a number of other customary closing conditions and regulatory approvals including Hart Scott Rodino. Throughout 2010, PV Powered will operate as a wholly-owned subsidiary, continuing to sell and support its PV Powered branded inverters.

Currently, we anticipate sales of PV Powered’s inverter to contribute as much as $40M-$50 million to Advanced Energy’s 2010 revenue. Of that, we expect $30-35 million to come from sales to the commercial market and $10-15 million from the residential market. We anticipate gross margins on these products to be in the range of 26-29% and have additional operating expenses of $3-4 million.

Needham & Company, LLC acted as the financial advisor and provided a fairness opinion to Advanced Energy related to this transaction.

Advanced Energy Announces Strong Growth and Profitability in Fourth Quarter Results

Fort Collins, Colo., February 16, 2010—Advanced Energy Industries, Inc. (Nasdaq GM: AEIS) today announced financial results for the fourth quarter ended December 31, 2009.

Sales for the fourth quarter of 2009 increased 28.4% to $66.4 million from $51.8 million in the third quarter of 2009, and decreased 1.6% from $67.5 million in the fourth quarter of 2008.

Sales to the semiconductor capital equipment markets rose 58.2% sequentially to $32.9 million, representing 49.6% of total sales for the quarter. Sales to the non-semiconductor markets grew 8.6% sequentially to $22.0 million, representing 33.2% of total sales for the quarter. Service revenue also continued strong, increasing 7.6% sequentially to $11.5 million or 17.3% of total sales for the quarter. Bookings for the fourth quarter were $98.0 million, which drove our book to bill ratio to 1.48:1, up from 1.16:1 in the third quarter of 2009. Ending backlog increased 91.2% sequentially to $66.2 million at the end of the fourth quarter compared to $34.6 million at the end of the third quarter of 2009.

Gross margin improved significantly to 36.8% in the fourth quarter, up from 30.1% in the third quarter of 2009 and 27.2% for the fourth quarter of 2008. The sequential improvement was driven largely by leverage against our fixed costs from the increase in revenues.

Fourth quarter net income was $1.5 million or $0.04 per diluted share, compared to a net loss of $8.4 million or a loss per share of $0.20 in the third quarter of 2009. In the fourth quarter of 2008, the net loss was $19.0 million or a loss per share of $0.45, the vast majority of which was a non-cash charge of $18.0 million for income taxes related to a valuation allowance against our deferred tax assets. We are pleased to report that we ended 2009 with cash, cash equivalents and investments of $177.5 million, a decline of just $2.6 million due to our careful cash management during the year.

For the full year 2009, sales were $186.4 million, 43.3% below sales of $328.9 million in 2008. The challenging economic environment impacted sales across all markets, most notably in the semiconductor capital equipment market where sales fell 43.1% from 2008. Net loss from operations for 2009 was $102.7 million, or a loss per share of $2.45. More than half of this was due to a non-cash goodwill impairment charge in the first quarter of 2009 of $63.3 million or $1.51 per share. Net loss for 2008 was $1.8 million or $0.04 per diluted share.

“The fourth quarter marked a high point in 2009, as we grew revenues and achieved profitability by leveraging the cost reductions taken during the year,” said Hans Betz, chief executive officer. “The pace of the recovery in the semiconductor capital equipment market ramped significantly in the quarter, as did the penetration of our Solaron inverters into larger, multi-megawatt projects. When the global economy recovers, we expect to benefit from the investments we made in technology during the downturn and our growth in multiple markets.”

First Quarter 2010 Guidance

• Sales of $77 million to $83 million
• Earnings per share of $0.13 to $0.17

Advanced Energy^® Solaron^® PV Inverters Selected for San Francisco Sunset Reservoir 5 MW Solar Project

Industry-Leading Efficiency Ratings and Lowest LCOE Fuel Momentum for Solaron

FORT COLLINS, Colo., Feb. 11, 2010—Advanced Energy Industries, Inc. (NasdaqGM: AEIS), today announced its Solaron^® PV inverters have been selected to power the San Francisco Sunset Reservoir 5 MW solar project. The project was awarded to Advanced Energy by Recurrent Energy, an independent power producer and a leading developer of solar power projects. Recurrent Energy will own and operate the solar power system, and is developing the project in partnership with the San Francisco Public Utilities Commission. The Solaron PV inverters were selected due to their record-setting efficiency ratings, field-proven LCOE (Levelized Cost Of Energy) advantages, and Advanced Energy’s outstanding customer service.

Dr. Hans Betz, chief executive officer of Advanced Energy, noted, “We are proud to be selected by Recurrent Energy to collaborate with them on this landmark project. Advanced Energy’s Solaron PV inverters have a strong reputation for optimized efficiency and the highest level of reliability for large-scale utilities. The project demonstrates the City of San Francisco’s commitment to renewable energy, and we are pleased to be able to help them achieve their goals.”

The 5 MW solar plant is being constructed on the roof of San Francisco’s largest reservoir, located in the city’s Sunset district. Construction is scheduled to begin this winter and is expected to be completed in 2010. Upon completion, the project will consist of 25,000 solar panels that span approximately 12 acres, making it one of the country’s largest municipal solar projects. The system will more than triple the City’s available renewable energy which can be used at numerous municipal facilities, including the San Francisco Airport, MUNI light rail system, the General Hospital and city schools.
