Why Is ENPHASE ENERGY INC (ENPH) Stock Down Today?

Enphase Energy shares fell 16.47% to $24.86, driven by a weak fourth quarter guidance that signaled a deepening slump in residential solar demand. The stock opened with a significant gap down, reflecting immediate market reaction to the company's disappointing third quarter results and lowered outlook.

What Happened

Enphase Energy reported third quarter revenue of $293.3 million, missing the estimated $304 million, while adjusted earnings per share came in at $0.41 against an estimate of $0.51. The company provided weak guidance for the upcoming quarter, citing continued declines in U.S. rooftop solar demand. This news triggered a sharp selloff that extended to residential-focused peers, with SolarEdge dropping 10%, Sunrun falling 5%, and First Solar dipping.
