About American Superconductor
American Superconductor provides power systems that connect large loads and generators to the electric grid cleanly. It earns revenue selling engineered grid interconnection equipment, power quality electronics, and superconductor-based products to utilities, industrial customers, renewable developers, and the US Navy.
Its D-VAR STATCOM systems stabilize voltage where big facilities meet the grid, and its NEPSI medium-voltage solutions handle power quality and harmonic filtering, products increasingly ordered for data centers, semiconductor fabs, and renewable interconnections. Amperium superconductor wire and ship protection systems round out the portfolio.
Founded in 1987 and headquartered in Ayer, Massachusetts, American Superconductor employs about 1,200 people and trades on the NASDAQ. The company also supplies power electronics for renewable energy systems and grid operators worldwide, with operations in North America, Europe, and Asia.
American Superconductor in the AI buildout
American Superconductor sits in the Utilities & Grid layer at the interconnection point. Every data center and fab that plugs into the grid needs voltage support and power quality equipment, and AMSC's D-VAR and NEPSI systems do exactly that job. Management has cited AI-driven grid demand in record order intake, making its exposure more direct than generic electrical suppliers. Wind energy and Navy work diversify the business but also add lumpiness to results.
AMSC is tracked in Utilities & Grid, rated Growing on the AI Exposure leaderboard.
