ITEM 5.   OTHER EVENTS

     With the Form 10-Q for the quarter ended December 31, 1997 filed with the
Securities and Exchange Commission (the "Commission") on February 13, 1998,
American Superconductor Corporation (the "Company") adopted Financial Accounting
Standard ("FAS") No. 128 relating to Earnings Per Share. Additionally, in
connection with the April 8, 1997 merger of a subsidiary of the Company into
Superconductivity, Inc., a Delaware corporation ("SI"), accounted for as a
pooling of interests, the Company prepared restated financial statements
reflecting such pooling of interests transaction. These consolidated financial
statements were filed by the Company with the Commission on Form 8-K filed on
September 5, 1997. The adoption of FAS No. 128 and the consolidated financial
statements reflecting the pooling of interests transaction both constitute a
restatement of the Company's financial statements.

     Item 601(c)(2)(iii) of Regulation S-K requires the Company to file restated
Financial Data Schedules for all periods affected by the restatement of the
Company's financial statements and accordingly, the Company is filing restated
Financial Data Schedules for the appropriate periods herewith.
