What We Like
- Safe-harbor agreements reached $843.6 million YTD, plus $67.7 million in Q4 physical work test orders.
- Meter collar approved by 64 utilities covering approximately 34 million customer accounts.
- IQ SST has working power modules, more than 20 prospective customers, and an initial annual U.S. addressable opportunity above 11 GW.
- Fifth-generation battery targets roughly 50% higher energy density and 40% lower cost.
- Propel prepaid lease scaled to 200+ installers, about 200 net originations per week, and 84% battery attach.
What We’re Watching
- Q1 sell-through fell 48% sequentially and 18% year over year; Q1 and Q2 are 10–15% below management's prior view.
- Channel inventory ended Q1 above normal; management is under-shipping about $25 million in Q2 to normalize it.
- Non-China LFP cell qualification went silent on the Q1 call; the 10-Q still discloses exclusive supply from two China vendors.
- IQ SST is pre-revenue: full system demo later 2026, pilots 2027, volume 2028.
The near-term thesis is weakening because underlying U.S. sell-through is below management's view and channel inventory is high. The strategic thesis is strengthening because the safe-harbor book and IQ SST announcement expanded the company's long-dated opportunity. The open question is whether Q2 2026 results confirm a trough in underlying sell-through or another step down.
Earnings Beat
Q2 FY2026 revenue was $291.9 million, reported gross margin was 60.0%, and EBITDA was $71.7 million (24.6% of revenue). Free cash flow was $25.9 million.

Trajectory
Reported gross margin moved from 35.5% in Q1 FY2026 to 60.0% in Q2 FY2026, while EBITDA swung from negative $8.8 million to positive $71.7 million. The source attributes the Q1 gross-margin trough partly to a $16.5 million discount on the sale of 2025 tax credits and a 4.3 percentage-point reciprocal tariff impact. Revenue fell to $282.9 million in Q1 and recovered modestly to $291.9 million in Q2, leaving trailing revenue growth negative.
The Model
The model projects FY+1 revenue of $1,181 million and EBITDA of $113 million (9.6% EBITDA margin), and FY+2 revenue of $1,320 million and EBITDA of $206 million (15.6% EBITDA margin). FY+2 revenue dispersion across the five runs is 17%, with a range of $1,220 million to $1,450 million. The source points to the multiyear safe-harbor book for near-term revenue support and fifth-generation battery shipping in Q4 2026 as a later margin driver.
| Metric | FY2025 | Next FY (E) | Following FY (E) |
|---|---|---|---|
| Revenue | $1.5B | $1.2B | $1.3B |
| YoY Growth | — | −19.8% | +11.8% |
| EBITDA | $236M | $113M | $206M |
| EBITDA Margin | 16.0% | 9.6% | 15.6% |
Projections are the median of 5 independent model runs. The model’s revenue sits 2.0% above analyst consensus.

What Could Go Right — and Wrong
- IQ SST full system demo later in 2026 leads to named 2027 pilots and 2028 volume orders.
- Europe's April activation increases in the Netherlands, France, and Germany persist into revenue.
- Propel expansion in July 2026 scales toward 500 originations per week by end of Q4.
- Fifth-generation battery reaches roughly 50% higher density and 40% lower cost on schedule in Q4 2026.
- Non-China LFP battery cells qualify at scale, removing the exclusive two-China-vendor concentration.
- U.S. core sell-through stays 10–15% below the prior view and Q2's roughly $25 million under-shipment does not normalize channel inventory.
- Tax-equity or TPO financing constraints stall Propel originations from converting into installed, monetized systems.
- SST demo slips or fails to convert more than 20 prospective customers into named pilots.
- Battery price cuts (12–14% U.S., about 10% Europe) fail to lift volumes, compressing margins.
- The unnamed 39% customer reduces orders or faces financing trouble.
Looking Ahead
The next twelve months test whether Enphase can stabilize the core while advancing the AI power option. Fifth-generation battery pilots begin in Q3 2026 and shipments in Q4 2026; the IQ SST full system demo is expected later in 2026; and bidirectional EV charger availability is targeted for Q4 2026. In parallel, Propel expansion in July 2026 and safe-harbor conversion through 2027–2030 are expected to show whether the U.S. residential recovery is financed and installed.
- Q3 2026Fifth-generation battery pilots — Pilot units in field ahead of Q4 shipping target.
- Later 2026IQ SST full system demo — Tests whether working power modules scale to a full system.
- Q4 2026Fifth-generation battery shipping — Q4 shipment start; tests targeted 40% lower cost.
- Q4 2026Bidirectional EV charger availability — Initial availability targeted; advanced discussions with two auto OEMs.
- Q1 2027IQ Board commercial battery pilots — Pilot announcement for 80 kWh AC-coupled system.
- 2027IQ SST customer pilots — Named pilot or deployment evidence.

The Company
Enphase is a global energy technology company founded in March 2006. It designs microinverters, residential and commercial batteries, EV chargers, and cloud-based solar design software. The 10-K says its intelligent microinverters work with virtually every solar panel made and, paired with the company's smart technology, result in one of the industry's best-performing clean energy systems. IQ8 microinverters ship into 58 countries; IQ9N-3P commercial microinverters began shipping in December 2025.
The company has moved a significant portion of manufacturing to the United States, with facilities in South Carolina and Texas. In November 2025 it commenced manufacturing at its Arlington, Texas facility previously operated by Salcomp Manufacturing USA Corp. In Q1 2026 it shipped about 1.39 million U.S.-made microinverters and 49.5 MWh of U.S.-made IQ batteries, while retaining limited contract manufacturing with Flex, Salcomp India, and Sunwoda.
Business Segments
Competitive Landscape
The 10-K identifies competitors across inverters, storage, and EV charging. Management describes competition as intense, particularly from low-cost string inverters and battery providers; the response includes a 12–14% U.S. battery price cut in March 2026 and a roughly 10% European battery cut planned for May.
