NXT trades at $88.77, up 4.61% today, with strong analyst support (86% buy ratings) and a $144.67 consensus price target suggesting 63% upside. The company has beaten earnings estimates for three consecutive quarters, with Q3 2026 results expected November 16. Revenue grew from $3.0B in 2025 to $3.6B in 2026, while maintaining robust profitability with 16.36% net margins and 27.22% ROE.
Positive outlook driven by $5.5B+ backlog and raised 2027 guidance, though rising platform investment costs and solar sector volatility present risks. Technical levels show support at $86 with resistance at $91, while valuation multiples (P/E 22.94, P/S 3.76) appear reasonable given growth trajectory.
