NEXTracker Inc (NXT) saw its stock surge 18.12% in the 24-hour period leading up to Tuesday's close, driven by the company's impressive fiscal Q3 2025 earnings report released after the market close.

The solar tracking systems provider reported quarterly earnings of $0.79 per share, significantly exceeding analyst estimates of $0.45 by a wide 75.56% margin. NEXTracker's Q3 revenue of $679 million also beat expectations, coming in 4.4% above the consensus estimate of $650.398 million despite a year-over-year decline of 4.42%.

Buoyed by the strong Q3 performance, NEXTracker raised its full-year fiscal 2025 GAAP EPS guidance range to $3.31-$3.11, up from the previous outlook of $2.70-$2.50. The company also reaffirmed its revenue guidance for the full year in the range of $2.8 billion to $2.9 billion. Analysts view NEXTracker's better-than-expected results and upwardly revised profit guidance as highly positive signals, driving the stock's surge.
