American Superconductor Corporation (NASDAQ: AMSC) experienced a significant stock rally of 44.2% in the first half of 2026, driven largely by improvements in superconductor technology and not solely by its earnings reports. The company reported revenue growth of 29.6% in the March quarter compared to 21.4% in December, while its backlog increased by 40% year-over-year.
The surge in AMSC’s stock price coincided with a February blog post by a Microsoft executive indicating the company’s interest in high-temperature superconductors for data centers, suggesting they are now economically viable. Additionally, an April study published in *Nature Physics* from Ohio State researchers proposed new materials that could lead to room-temperature superconductivity, further bolstering market confidence in AMSC’s technology. The company’s current earnings are primarily from traditional utility products, as superconductor technology remains in the experimental phase.
