Enphase tumbles 20% after Q3 miss, weak Q4 revenue guidance

What happened

Enphase Energy fell 20.2% before the market opened after third-quarter results missed analyst expectations and it guided fourth-quarter revenue to $225M-$255M, below the $297.6M consensus, citing weak residential demand. Revenue dropped 28% from a year earlier.

Confirmed

Global impact / market context

Enphase sells solar equipment tied closely to home installations, so weaker residential demand cuts its revenue and profit. Because it guided the next quarter well below expectations, investors expect slower sales ahead, which is why the stock fell sharply and solar peers also moved lower.

Analyst inference

Higher interest rates make financed solar systems costlier for homeowners, and the expired Section 25D federal tax credit, which means a tax benefit for residential solar, removes an incentive. This pressures demand across residential solar companies such as Sunrun, while utility-scale names like First Solar are less directly exposed.

Analyst inference

What to watch

1. Enphase forecast fourth-quarter adjusted gross margin, which means profit per sale after certain costs, at 40%-43%, including two percentage points of tariff impacts. Confirmed
2. Enphase said it is addressing near-term challenges through five growth drivers heading into 2027, including a fifth-generation residential battery and a prepaid lease program to encourage adoption. Proposed
3. Watch whether higher interest rates and the expired Section 25D tax credit keep weighing on residential solar demand, and whether Enphase's new battery and lease offerings offset weakness before 2027. Analyst inference
