Shares of Enphase Energy cratered 15.7% to $25.10 after the company's October 27 earnings release delivered a double miss on revenue and profits, then compounded the damage with fourth-quarter guidance roughly 20% below what Wall Street had penciled in. The broader market was essentially flat on the day, meaning the selloff was entirely company-driven.
U.S. Homeowners Aren't Buying, and the Numbers Show It. Global sell-through — the rate at which products actually reach end customers — grew just 1% sequentially versus expectations of 10% growth.
U.S. sell-through declined 35% year-over-year, while European sell-through fell 12% sequentially due to seasonality and weakness in markets like France. The culprits are straightforward: higher interest rates and the expiration of the Section 25D federal tax credit have made rooftop solar a harder sell for homeowners already squeezed by borrowing costs. This isn't a one-quarter blip — global sell-through has remained relatively flat over the first three quarters of 2026, and management is "not seeing any meaningful recovery" in U.S. demand.
Margins Are Compressing From Multiple Directions. Operating income fell 90% year-over-year to $6 million, and gross margins contracted 450 basis points to 43.3%, driven by pricing pressure and unfavorable manufacturing cost absorption.
Q4 guidance calls for adjusted gross margin of 40%–43%, including roughly 2 percentage points of tariff impact — meaning profitability could tighten further even as revenue drops.
The Q4 Guidance Gap Is the Real Shock. The Q4 revenue guidance midpoint of $240 million was substantially below the analyst consensus of approximately $300.5 million , a miss of roughly 20%. Current demand levels have not yet bottomed , suggesting estimates for 2027 may also need to come down.
Management's Five-Pillar Growth Plan Faces an Execution Clock. The company plans to focus on residential batteries, U.S. residential solar recovery, commercial solar and battery products, bidirectional EV charging, and power electronics for AI data centers. These are real markets, but customer pilots for the data-center product aren't expected until 2027, with commercial shipments beginning in 2028.
The pivot reduces long-term dependency on volatile residential demand but introduces significant execution risk. Meanwhile, the stock now trades near its 52-week low of $25.78 — versus a 52-week high of $73.74 — leaving shareholders to decide whether the price already reflects the worst, or whether more pain lies ahead.
