Enphase Energy Beats EPS But U.S. Solar Demand Cracks After Tax Credit Expires
NEW YORK, April 29 —
Enphase beat on EPS, missed on the only number that matters: U.S. revenue is shrinking now that the federal solar tax credit is gone.
- Q1 2026 EPS topped Zacks consensus, but adjusted earnings and revenue both fell YoY
- Stock at $34.3, trading at 13.0x forward P/E on $1.5bn TTM revenue, a multiple that already prices in slowdown
- Q2 revenue guidance and any order traction on the new AI data center transformer is the next catalyst
What Actually Happened
Enphase delivered the classic mixed quarter: a beat on the bottom line, a step backward on the top. The beat is mostly cost discipline. The miss is structural. With the federal residential solar tax credit having expired, the U.S. installer channel that drives Enphase's microinverter volume has gone quiet. Shares slipped in after-hours trading, which tells you investors are reading past the EPS print and looking at the demand curve.
The interesting wrinkle is the product announcement buried alongside the print: a new transformer designed for AI data centers, pitched as a way to free up GPU rack space. That is a different customer, a different sales cycle, and a different growth story than residential rooftops.
The Catch
One transformer SKU does not make Enphase a data center power company. Vertiv, Eaton, and Schneider already own that wallet, and they sell across the entire stack, not a single component. Until Enphase reports a backlog number tied to hyperscaler customers, the AI angle is a press release, not a P&L line. Meanwhile the residential business, which is the real cash engine, is contracting on policy, not preference. Tax credit expirations have sunk solar names before. SunPower delisted. SunRun cratered. Policy risk is not a headwind, it is the wind.
Bottom Line
Enphase looks cheaper than it has in years, but cheap on declining U.S. demand is a value trap until management proves the AI pivot has revenue attached. The 13x forward multiple is doing some work here: the market is paying for a recovery that may or may not arrive in 2026. Growth investors should wait for an order. Value investors should wait for the trough. The number to watch is Q2 revenue guidance. If management cuts the U.S. outlook again, $34 is not the floor.
