Enphase reported adjusted earnings per share of $0.71 on quarterly revenue of $343.3 million, topping consensus estimates by more than 10% on both lines. The outperformance was driven largely by safe-harbor shipments, which bolstered revenue by an estimated $25 million compared with management’s initial guidance. Gross margin expanded approximately 600 basis points year-over-year to 41.8%, reflecting tighter cost controls and improved inverter yields in its European and North American channels.

Shares surged over 50% in early trading the day after the earnings release, marking one of Enphase’s biggest single-day moves since early 2020. Over the prior six weeks, the stock had rallied more than 40% from multi-year lows, drawing both institutional and retail interest. Analysts attribute the rebound to shifting sentiment around channel inventory normalization, accelerating international demand and the perception that the firm’s microinverter technology is gaining traction beyond residential solar into commercial and data-center applications.

Management issued Q1 revenue guidance of $270 million to $300 million, implying sequential growth of 15% at the midpoint and operating margins of 42%–45%. This outlook prompted multiple firms—including major U.S. banks and European brokerages—to lift their ratings and price targets by up to 55%. Analysts cited the safe-harbor effect continuing to underpin early-year shipments, while noting fundamental demand trends remain supportive across key U.S. and European markets.

Enphase registered a decisive technical breakout, driving a short squeeze as short interest stood at 22.7% of float heading into earnings. With a days-to-cover ratio above five, forced cover accelerated the rally, especially after more than 60% of trading occurred off-exchange in dark pools. The 50-day moving average is now converging on the 200-day line—a potential Golden Cross that could attract momentum-driven flows if confirmed in the coming sessions.
