Enphase Energy faced a sharp revenue decline of 20.6% year-on-year, with Q1 2026 sales at $282.9 million, triggered by weakened demand in the U.S. solar market. Although adjusted earnings of $0.47 per share exceeded analysts' expectations, they represent a stark 30.9% drop compared to last year. Looking ahead, the company anticipates further challenges, projecting an 18.8% decline in sales next quarter, while competition from low-cost providers in Europe continues to pressure its market share.
