Enphase Energy delivered fourth-quarter revenue and profitability ahead of consensus, with total shipments up 12% year-over-year. The company credited a sizeable safe harbor benefit—recognized in Q4—for the outperformance, which contributed approximately $50 million of incremental revenue. Gross margin expanded by 180 basis points sequentially, reflecting higher average selling prices and operational leverage in its microinverter segment. Enphase generated $37.8 million in free cash flow during the quarter and ended with $1.51 billion in cash, cash equivalents and marketable securities on the balance sheet. Management reiterated that comparable safe harbor recognition will lift previously stated guidance for the first quarter, where revenue is now expected between $270 million and $300 million with operating margins in the 42%–45% range.

On February 4, Enphase shares surged 34%, marking the company’s strongest single-day performance since early 2020. The move followed the better-than-expected Q4 report and bullish first-quarter outlook, catching a crowded short trade off guard. As of quarter-end, short interest stood at 22.7% of the float with a days-to-cover ratio of 5.1, setting the stage for a rapid squeeze once momentum turned positive. More than 60% of trading volume occurred off-exchange, suggesting dark-pool participants were particularly exposed. Technical indicators now point to a potential Golden Cross, as the 50-day moving average closes in on the 200-day, which could draw additional trend-followers into the rally.
