The business, in plain English

American Superconductor Corporation booked $299.2M of revenue in FY2026 in the Industrials sector and kept 30.5% of it as gross profit — a moderate-margin business by that measure. After every other cost, 44.7% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $182.8M (FY2009) to $299.2M (FY2026) — about 2.9% a year compounded over 17 years.

It earned 2.8% on invested capital in FY2026, with a median of −38.0% across 18 filed years. The Returns on Capital filter above scores it 4/100.

The balance sheet carried $0 of total debt in FY2025. Balance-Sheet Safety scores it 100/100.

The share count rose 6.2% between FY2010 and FY2026 — existing owners have been diluted over the record. Capital Discipline scores it 24/100.

Put together: Balance-Sheet Safety is the strongest of the four filters (100/100) and Returns on Capital the weakest (4/100), which is how AMSC lands at 30/100 — a None moat.
