<DIV align="left" style="font-size: 10pt; margin-top: 6pt">American Superconductor Corporation (the &#147;Company&#148;) is unable,
without unreasonable effort or expense, to file its Annual Report on Form 10-K for the fiscal year ended
March 31, 2011 (the &#147;Form 10-K&#148;) with the Securities and Exchange Commission (&#147;SEC&#148;) by its May 31, 2011
filing deadline.  Additional time is required to complete the preparation of the Company&#146;s financial statements
to be included in the Form 10-K, including a review of certain revenues associated with shipments to customers in
China during the second, third and fourth fiscal quarters of the fiscal year ended March 31, 2011.  In connection
with this ongoing review of each of these quarters, the Company currently expects to reverse the recognition of a
 material amount of revenue that the Company had included in the
calculation of its estimated revenues of &#147;less than $355
million&#148; for the full fiscal year in
the Company&#146;s press release dated April 5, 2011.  Management has also identified a material weakness with
respect to the administration of customer contracts in China and is reviewing additional matters relating to the Company&#146;s internal control over financial
reporting. The Company does not expect to complete its assessment of the effectiveness of its internal control over financial
reporting and its disclosure controls and procedures until the completion of its review of these matters, which is ongoing as of
the date of this filing.  As a result, the Form 10-K could not, without unreasonable effort and expense, be filed before its May 31, 2011 deadline.
The Company expects to file the Form 10-K as soon as practicable.</DIV>
