Enphase Energy enters its third-quarter report with a split personality. One side of the story is genuinely improving: gross margins have recovered, Europe is rebounding, Safe Harbor orders are piling up, and the product pipeline now reaches from GaN microinverters to transformers for AI data centers. The other side is a U.S. residential business that keeps shrinking. Since the last report, the market has sided firmly with the pessimists, and this quarter has to show that the core has stabilized rather than slid further.
The Street is looking for non-GAAP earnings of $0.47 a share on revenue of $303.7 million, a 26% drop from the $410.4 million posted a year ago. The revenue estimate sits comfortably inside management's $290 million to $320 million range and just below its $305 million midpoint, so analysts are not asking for heroics. The Earnings Whisper of $0.45 is a touch below consensus. That gap is small, but it suggests the more skeptical crowd is bracing for a slight miss. Earnings have slid from $0.90 a share to $0.71, $0.47 and then $0.46 over the past four quarters, so a print near $0.47 would mark the first real pause in that decline.
The headline revenue number can hide a lot. Management's guidance implied only about $230 million of core revenue, excluding Safe Harbor, and included roughly $15 million of deliberate undershipment to distributors who remain cautious. Revenue that lands near the top of the range because Safe Harbor carried the load would be less reassuring than a steadier core with channel inventory clearing. U.S. sell-through fell 34% from a year earlier last quarter. Any sign that the decline is narrowing would support management's view that the market is bottoming. Another sequential drop would undercut it. Battery shipments, guided at 130 to 150 megawatt-hours, are a useful cross-check on whether attach rates are holding up.
Margins are the strongest part of the bull case. Non-GAAP gross margin rebounded to 46.8% from a 43.9% trough as Enphase shifted to non-Chinese cells and the drag from reciprocal tariffs shrank to about 2 points. Guidance of 44% to 47% leaves room to disappoint, so margins holding near the upper half would confirm the recovery is structural. Europe deserves similar scrutiny. Revenue there jumped 35% sequentially, and battery activations in the Netherlands roughly doubled ahead of the end-2026 net-metering phase-out. Continued momentum would show that growth is real and not just a pull-forward. The newer catalysts need progress reports as well. Propel, the prepaid-lease program, was meant to reach 12 states and climb toward 500 weekly originations by year-end from about 200. The G5 battery is due to ship before year-end, and the data-center transformer effort has moved into formal requests for proposals.
The tape tells its own story. Shares have fallen 21.3% since the last report while the S&P 500 gained 3.2%. At $30.62, the stock sits well below its 200-day moving average of $41.16 and near the bottom of its post-earnings range of $28.59 to $43.28. Sentiment has nonetheless softened from 13.4% bearish to 4.4% bearish, a sign the market may have already priced in much of the U.S. weakness.
The overriding question is whether the core business is stabilizing on its own. Margin strength and Europe can buy patience, and the long-dated data-center story offers optionality. But if core revenue, excluding Safe Harbor, slips again and management signals more undershipment into the fourth quarter, the recovery thesis will keep getting pushed out. If U.S. sell-through flattens and distributor caution starts to lift, the depressed share price leaves meaningful room for relief.
