424B5
Capital/Financing Update Classification · 100% confidence The document is a prospectus supplement filed pursuant to Rule 424(b)(5) related to a common stock offering by American Superconductor Corporation. It includes detailed information about the offering, risk factors, use of proceeds, underwriting, and other legal and financial disclosures typical of a securities offering document. The presence of terms like 'prospectus supplement', 'common stock offering', 'underwriting discounts and commissions', and references to the Securities and Exchange Commission (SEC) registration and approval indicate this is a capital raising document. It is not a financial report, earnings release, management discussion, or any other type of report but specifically a document related to capital/financing activities. Therefore, the appropriate classification is Capital/Financing Update (CAP). The document length (15,000 characters) and content confirm it is the actual offering document, not just an announcement or a brief notice.

FORM 8-K
Capital/Financing Update Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The text includes an announcement of preliminary financial results for the fourth quarter and full fiscal year ended March 31, 2015, but it is a press release attached as an exhibit rather than the full financial report itself. The document also details a reverse stock split and amendments to the certificate of incorporation and bylaws, which relate to capital stock changes and governance provisions. The document is not a full annual or quarterly report, nor is it a transcript or detailed management discussion. It is primarily an announcement of financial results and corporate actions. Given the nature of the Form 8-K and the content, the best fitting category is Capital/Financing Update (CAP) because it includes a reverse stock split and capital stock description updates, along with financial results announcement. The document length is substantial and contains detailed information, not just a brief announcement, so it is not a Report Publication Announcement (RPA). Therefore, the classification is CAP with high confidence.

8-K
Legal Proceedings Report Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce unscheduled material events or corporate changes. The text describes a legal proceeding update regarding a court decision and the company's intention to appeal. It does not contain financial statements or detailed financial data, nor is it a full annual or quarterly report. The document is not a certification or a proxy statement, nor is it an announcement of a report publication. The content fits best under Legal Proceedings Report (LTR) as it provides an update on a significant lawsuit involving the company.

8-K
Regulatory Filings Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC, dated April 9, 2015, by American Superconductor Corporation. It discusses a notification from Nasdaq regarding the company's compliance with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market. The content is an update on a regulatory compliance event related to stock listing standards, not a full financial report, earnings release, or management discussion. The document is relatively short (3426 characters) and serves as a regulatory announcement about the company's stock listing status. Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory announcements that do not fit other specific categories.
