AMERICAN SUPERCONDUCTOR CORPORATION
AMERICAN SUPERCONDUCTOR CORPORATION is a Public Limited Company registered in United States under 042959321, and its current status with Massachusetts Secretary of the Commonwealth is active. The company was incorporated on 17 April 1987 and lists its registered address as United States. 2 shareholders are on record for AMERICAN SUPERCONDUCTOR CORPORATION, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Massachusetts Secretary of the Commonwealth and was last updated on 3 October 2026.

Shareholders
2
Two shareholders are currently on record for AMERICAN SUPERCONDUCTOR CORPORATION, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 16.5% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 2.1%.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
| Shareholder | Type | Holding | Source Document |

Officers
5
The Chairman Of The Board/president/ceo of AMERICAN SUPERCONDUCTOR CORPORATION currently on record is DANIEL MCGAHN; five officers are currently on record for AMERICAN SUPERCONDUCTOR CORPORATION, filed with Massachusetts Secretary of the Commonwealth.
The register reports 26 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at AMERICAN SUPERCONDUCTOR CORPORATION sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
AMERICAN SUPERCONDUCTOR CORPORATION has no recorded parent company — it sits at the top of its own group structure, with 17 subsidiaries recorded beneath it across 8 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 17 subsidiaries span United States, Brazil, Austria, Australia, India, Romania, and 2 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Two of the 17 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
