Enphase Energy Hits Record Low After Q3 Miss and Weak Q4 Guidance Spark Wave of Analyst Downgrades

Enphase Energy shares collapsed to a record intraday low of $23.84 on October 28, falling more than 20% after the solar microinverter maker reported third-quarter 2026 revenue of $293.3 million, which came in at the low end of its own guidance and missed analyst expectations. The company shipped approximately 1.42 million IQ Microinverters and 129.9 megawatt hours of IQ Batteries in the quarter, while non-GAAP gross margin slipped to 45% from 46.8% in the second quarter.

The steeper blow was fourth-quarter guidance of only $225 million to $255 million, a sharp sequential drop that management attributed to soft U.S. residential solar demand, elevated channel inventory, higher interest rates, and the upcoming expiration of the federal Section 25D tax credit. The stock has now fallen roughly 60% from its peak last year, with market capitalization dropping from approximately $9.5 billion to around $3.9 billion.

The results triggered a flurry of analyst actions. Oppenheimer downgraded Enphase to Perform from Outperform, and Roth Capital cut it to Neutral from Buy with a $30 price target. JPMorgan, Mizuho, and Susquehanna all reduced their price targets while maintaining existing ratings. The sector-wide damage was significant: SolarEdge fell 10%, Sunrun dropped 5%, and First Solar also declined, as investors read Enphase's outlook as a broad signal of continued weakness in the U.S. rooftop solar market.

Separately, Enphase unveiled a 900-volt GaN AI data center power platform, an attempt to diversify beyond residential solar, though the announcement did little to offset the negative earnings reaction.
