American Superconductor Corporation approved a Fiscal 2026 Executive Incentive Plan for the fiscal year ending March 31, 2027. The plan covers the chief executive officer and all current executive officers, providing annual cash bonuses based on performance against defined factors and weightings.
Each executive has a target cash incentive set as a percentage of base salary, with actual payouts ranging from zero up to 200% of the target. The chief executive officer’s target incentive is 100% of base salary, or $754,000, while the chief financial officer’s target is 75% of base salary, or $351,000. The Compensation Committee determines payouts for executives other than the CEO, and the Board sets the CEO’s payout based on the Committee’s recommendation.
American Superconductor Corporation reports a year of profitable growth driven by grid, industrial and naval power solutions and two acquisitions. It bought Brazil-based transformer maker Comtrafo in December 2025 and U.S. power conversion group Megatran/NWL in August 2024, expanding its Grid segment.
The company estimates an annual addressable market of over $15 billion, supported by $2.3 trillion of 2025 global energy-transition investment and rising U.S. defense and shipbuilding spending. International sales are significant, with 52% of fiscal 2025 revenue coming from outside the United States and notable customer concentration with Inox in its Wind segment.
AMSC ended March 31, 2026 with $147.6 million in cash, cash equivalents and restricted cash and generated $23.1 million of operating cash flow. It released a $118.4 million deferred tax valuation allowance after achieving profitability but disclosed a material weakness in controls over acquisition accounting, which management is working to remediate.
American Superconductor (AMSC) reported strong growth for the fourth quarter and fiscal year ended March 31, 2026. Fourth-quarter revenue rose to $86.4 million from $66.7 million, with GAAP net income increasing to $4.5 million, or $0.10 per share. Non-GAAP net income for the quarter climbed to $14.1 million, or $0.31 per share.
For fiscal 2025, revenue grew 34% year over year to a recent record of $299.2 million, driven by higher Grid and Wind sales and contributions from the Comtrafo acquisition. Full-year GAAP net income was $133.8 million, or $3.12 per share, largely reflecting a substantial non-cash tax benefit from releasing most of the valuation allowance on deferred tax assets. Full-year non-GAAP net income rose to $158.1 million, or $3.68 per share.
AMSC ended March 31, 2026 with $147.6 million in cash, cash equivalents and restricted cash and a 12‑month backlog of approximately $280 million, nearly 40% higher year over year. For the quarter ending June 30, 2026, the company expects revenue to exceed $85 million, GAAP net income to exceed $3.0 million, and non-GAAP net income to exceed $8.0 million, or $0.17 per share.
