Enphase Energy, Inc.

What they do

Enphase designs, develops, and sells home energy solutions including IQ Microinverters, IQ Batteries, IQ Load Controllers, and IQ EV Charger, managed via a cloud-based platform and app. The company sells primarily to solar distributors, who combine products with modules and racking, and also directly to large installers, OEMs, and strategic partners. As of June 30, 2026, it had shipped approximately 89.4 million microinverters and deployed more than 5.3 million systems in over 165 countries.

Revenue drivers

• IQ Microinverters — Core product line, shipping approximately 1.59 million units (725.2 MW DC) in Q2 2026; primary revenue source.
• IQ Batteries — Energy storage product, shipped 113.8 MWh in Q2 2026 (up from 103.1 MWh in Q1); growing segment with over 25,000 certified installers.
• Safe harbor revenue — Revenue from agreements tied to ITC safe harbor and physical work test, contributing $84.3 million in Q2 2026 versus $34.5 million in Q1 2026.
• European operations — International growth driver, with revenue in Europe increasing approximately 35% in Q2 2026 versus Q1 2026, while US revenue decreased ~3%.

Recent performance

In Q2 2026, Enphase reported revenue of $291.9 million, up from $282.9 million in Q1 2026 but down from $363.2 million in Q2 2025. GAAP gross margin was 60.0%, boosted by $45.4 million in US Customs refunds; non-GAAP gross margin was 46.8%. GAAP net income was $36.1 million (diluted EPS $0.27), while non-GAAP net income was $61.5 million (diluted EPS $0.46). Free cash flow was $25.9 million, ending cash and marketable securities at $937.7 million.

Strategy

Management emphasizes expanding the Enphase Energy System with a single platform for solar, storage, load control, and EV charging. The company is investing heavily in R&D, including accelerated development of the IQ Solid-State Transformer (IQ SST) for AI data centers, targeting potential multi-gigawatt opportunities. It is also pursuing growth in the third-party ownership (TPO) market, executing agreements year-to-date totaling approximately $1.08 billion. Manufacturing diversification is a priority, with microinverters shipped from Texas and South Carolina facilities.

Risks

• Government subsidy changes — The Section 25D credit for residential solar and storage expired December 31, 2025, and new timing requirements under Section 48E may limit eligibility for leased systems, potentially reducing demand.
• Tariff exposure — Reciprocal tariffs reduced non-GAAP gross margin by approximately 2.0 percentage points in Q2 2026, and further tariff changes could materially impact results.
• Revenue volatility from safe harbor — Timing of revenue recognition and cash flows related to safe harbor agreements is variable, creating quarter-to-quarter fluctuations as seen with the $49.8 million jump in safe harbor revenue from Q1 to Q2 2026.
• Macroeconomic and geopolitical conditions — Supply chain disruptions, inflation, and geopolitical developments could harm operations and financial performance, as noted in forward-looking statements.

Outlook

Management is focused on advancing the IQ SST product for data centers, with customer engagements at RFI/RFP stages and a potential multi-gigawatt pipeline. They expect continued growth in TPO market engagement and are managing tariff impacts that are moderating, though still affecting gross margin. The company is expanding international revenue, particularly in Europe, and investing in R&D to support new product development.
