AE Launches Euro-Centric Web Site

Fort Collins, Colo., Mar. 25, 2003—Advanced Energy Industries, Inc. (Nasdaq: AEIS) today announced the launch of its newest customer-service resource, a European-focused Web site that will facilitate accessibility to general corporate and product information about Advanced Energy. Located at www.advanced-energy.de and accessible from the company’s corporate site, www.advanced-energy.com, this inaugural European site initially is designed for AE’s German-speaking customers. As AE’s first phase in providing its European customers online access to company and product information, phase two includes the company’s future plans to extend this access with additional European-language sites.

 

Last year, Advanced Energy greatly expanded its presence in Europe to enable closer proximity to its customers. In April 2002, AE acquired radio-frequency (RF) power solutions provider Dressler HF Technik GmbH (www.dressler.com). Headquartered in Stolberg, Germany, Dressler has a large presence in Germany, with substantial design and manufacturing facilities. In addition, last January, AE acquired Aera Japan, Ltd.-a leading global supplier of mass flow technology, with facilities in Dresden and Kirchheim. According to Kamel Ferdi, general manager of Europe for Advanced Energy, “This new Web site facilitates easy access to valuable product and company information for our European customers. We anticipate that these sites will become primary tools to help meet customers’ needs around the world.”

“Real-time information access and communication capability are critical to our global business model. This means not only having facilities where our customers are, but utilizing the technology at our disposal to ensure they can work with us, unimpeded by geographical limitations, 24 hours a day,” commented Doug Schatz, Advanced Energy chairman, CEO and president. “As a result of our effectively executing on our corporate strategy and roadmap, our European customer base is growing steadily. We are pleased to provide this valuable resource that will facilitate our European customers’ ability to achieve their time-to-market and other goals.”

Designed to parallel Advanced Energy’s corporate site, the new German-language site will include the following sections:

• Corporate information-Company history, locations and product overviews
• Link to Advanced Energy’s corporate website
• Product information-Gas and liquid flow management; ion and plasma sources; power management; thermal sensing and control; connectivity products; RF power, plasma and related products; and manufacturing services.
• News-AE European-specific news and events
• Company contacts-AE office locations, maps and key contacts, as well as distributors and representatives.
