American Superconductor Announces Termination of Research Program with ABB and EDF on Development of HTS Transformer Wire.

Companies to Explore Alternate HTS Wire Methodologiesand Architectures

American Superconductor Corporation (Nasdaq: AMSC) announced today the termination of funding for a research program it has been conducting to develop high temperature superconductor (HTS) wires for use in transformers. The research program was started April 1, 1997 and has been funded equally by ABB, Electricite de France (EDF) and American Superconductor.

American Superconductor, EDF (one of the world's largest electric utilities and a major shareholder in American Superconductor), and ABB intend to continue joint evaluation of American Superconductor's HTS technologies for use in transformers on a no-funds-exchanged basis.

"Based on the results of our work with EDF and ABB, we have made a mutual strategic decision to end the current development program on HTS transformer wire," commented Greg Yurek, American Superconductor's chief executive officer. "Our efforts will now focus on exploring alternate approaches and wire architectures for HTS transformers."

Yurek noted that American Superconductor's business model has reflected that the market for HTS transformers is expected to commence and grow rapidly in the second half of this decade. "We believe that HTS transformer wires will be a major market opportunity for American Superconductor in the future," said Yurek.

The intellectual property rights developed on HTS wires during the course of the research program remain the property of American Superconductor. ABB retains an exclusive license from American Superconductor for intellectual property rights on transformers developed during the course of the research program. "We intend to use this new base of knowledge in creating the most effective and profitable pathways to developing HTS transformer wires to meet the needs of this future market opportunity," said Yurek.

ABB and EDF would have provided an additional $1.2 million in development funds over the next 12 months had they continued with the program.
