American Superconductor Delivers Solid Q4 Performance

American Superconductor announced fourth-quarter revenue totaling $86.4 million for its fiscal year 2025. This figure represented a substantial 30% year-over-year improvement compared to the $66.7 million recorded during the corresponding quarter of the previous year. The company attributed this revenue expansion to organic growth momentum within both its Grid and Wind operating divisions.

Revenue contributions from the recently acquired Comtrafo business further bolstered quarterly results. Strong purchasing activity from utility providers and industrial clients helped broaden the company’s revenue foundation. According to AMSC, growth stemmed from conventional energy infrastructure projects as well as emerging data center power requirements.

Net income for the quarter came in at $4.5 million, equivalent to $0.10 per diluted share. This represented a meaningful improvement from the $1.2 million, or $0.03 per share, reported in the year-ago quarter. On a non-GAAP basis, adjusted net income totaled $14.1 million, translating to $0.31 per diluted share.

Annual Performance Reflects Continued Revenue Expansion

For the complete fiscal year 2025, AMSC generated total revenue of $299.2 million. This compared favorably to the $222.8 million recorded during fiscal 2024, demonstrating sustained expansion across its primary market segments. The company noted that both Grid and Wind divisions delivered revenue growth, supplemented by incremental contributions from the Comtrafo integration.

Annual net income surged to $133.8 million, representing $3.12 per diluted share. This marked a dramatic increase from the $6.0 million, or $0.16 per share, achieved in fiscal 2024. The substantial year-over-year improvement primarily resulted from a significant non-cash tax benefit associated with previously deferred tax assets.

Additionally, AMSC reported adjusted non-GAAP net income of $158.1 million, or $3.68 per diluted share. This figure stood well above the prior year’s $24.0 million, or $0.65 per share. As of March 31, 2026, the company maintained combined cash, cash equivalents, and restricted cash reserves totaling $147.6 million.

Expanding Data Center Opportunities Strengthen Business Pipeline

AMSC concluded fiscal 2025 with strengthened order momentum and an enlarged project backlog. Fourth-quarter bookings approached the $100 million threshold, fueled by conventional energy infrastructure investments and utility-connected data center initiatives. The company’s 12-month backlog increased nearly 40% on a year-over-year basis, reaching approximately $280 million.

The company operates within power management markets spanning grid infrastructure, wind energy generation, and industrial applications. Its technology solutions enable clients to address sophisticated energy challenges while maintaining operational efficiency. This positioning aligns AMSC with secular trends including electrification acceleration, grid modernization, and enhanced power system reliability.

Looking ahead to the first quarter ending June 30, 2026, AMSC anticipates revenue exceeding $85.0 million. The company projects net income above $3.0 million, corresponding to at least $0.07 per diluted share. On a non-GAAP basis, adjusted net income is expected to surpass $8.0 million, translating to more than $0.17 per diluted share.
