How asset managers voted at the American Superconductor Corporation 2025-2026 meeting

Each item below shows how the 235 asset managers that disclosed a American Superconductor Corporation vote in their SEC Form N-PX filings actually voted. Share totals are the shares those managers' funds voted, summed across every fund they report. These are reported items, not a count of the ballot: fund filings describe one ballot item in different words. Two descriptions are shown as one item only on evidence — the same text (or one cut short of the other), the same director nominee, or a match to the same row of American Superconductor Corporation’s own Form 8-K tally — never because they merely read alike. A description that could not be joined that way is listed on its own, so one ballot item can appear more than once.

Fund voting reports and institutional-manager reports both cover this item. An institutional manager can report shares that a fund it advises also reports, so the two are shown separately below and never added together, and their sum is not shown (fund and manager reports combined may count the same shares twice). The figure above is FOR ÷ (FOR + AGAINST + WITHHELD) of the shares these managers voted; abstained and unvoted shares are in neither half, and these managers are a subset of all shareholders, not the meeting result.

Largest American Superconductor Corporation shareholders voting in 2025-2026

Ranked separately for each type of Form N-PX report. An institutional manager can report shares that a fund it advises also reports, so the two tables can list the same shares and are never added together. Each is ranked by the shares voted on the item that the most managers of that type reported, shown as a share of the 45,160,926 shares outstanding at the time of that meeting.

About this page

Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered funds disclose how they voted every proxy and institutional managers disclose their votes on executive pay (say-on-pay, say-on-frequency and golden parachutes), and Form 8-K Item 5.07, in which the company reports its own meeting results. Shares outstanding are taken from American Superconductor Corporation’s 10-Q dated July 25, 2025. This page is a static snapshot rebuilt weekly on October 18, 2026; a live search always shows the current data.

At American Superconductor Corporation's shareholder meeting held July 25, 2025, in the 2025-2026 proxy season, 235 asset managers reported how they voted in their SEC Form N-PX filings, covering 1,834 separate fund positions. Their filings are grouped here into 9 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. American Superconductor Corporation's own Form 8-K tally for this meeting is published below, but no row in it could be matched to the most widely held item, so this page states no certified outcome for that item. On that item — To approve, on an advisory basis, the compensation of AMSC's named executive officers. — the reporting funds and managers cast 94% of the shares they voted in favour (FOR divided by FOR plus AGAINST plus WITHHELD; abstained and unvoted shares are excluded because neither took a side). Fund and manager reports are combined in it and may count the same shares twice: it adds fund reports to institutional-manager reports, which can cover the same shares. It is not the company's certified result.
