Enphase Energy, Inc. Q3 FY2026 earnings call

• Financial & Operational Metrics: Shipped 1.42 million microinverters and 129.9 MWh of batteries. Channel inventory is slightly above normal. Customer service NPS was 79% with ~1.9 minute wait times.
• U.S. Residential Market: Sell-through increased 5% sequentially but declined 35% year-over-year due to high interest rates and the expiry of the 25D tax credit. Commercial sell-through grew ~50% sequentially driven by IQ-9 commercial microinverters.
• International Markets: Europe saw an 11% sequential revenue decline due to summer seasonality and weak demand in France. Germany activations were down 5% sequentially.
• Growth Driver 1 (Residential Batteries): Targeting 450 MWh shipments in 2026, aiming for 50% growth in 2027. Key catalyst is the next-gen IQ Battery G5 (30 kWh/stack), enabling 'one box on the wall' installations in Australia, Netherlands, and Germany.
• Growth Driver 2 (Propel): A prepaid lease program (SolSource/Tribeam/Green Tech) to replace expired 25D credits. Now active in 13 states with >300 weekly originations and ~71% battery attach rate.
• Growth Driver 3 (Commercial): Expected to grow from $30M (2026) to >$100M (2027). Launched IQ Battery C80 for small commercial storage, targeting demand charge reduction. FCC restrictions on foreign inverters provide a competitive advantage.
• Growth Driver 4 (EV Charging): Bidirectional EV charging solutions (AC/DC) launching in Q1 2027. Partnerships with three top U.S. auto OEMs. Anticipated $15-20M revenue in 2027, scaling to >$100M annually later.
• Growth Driver 5 (AI Data Centers/IQSST): Solid-state transformer converting 13.8kV/34.5kV AC to 800V DC. Achieved 13.8kV demo; 34.5kV demo expected Q4. Pipeline includes two global tech leaders. Potential for $1B annual revenue by 2030.

Total Q3 revenue was $293.3 million, representing a sequential increase of approximately 1%. The U.S. market contributed 80% of revenue with a 3% sequential increase, while international markets contributed 20% with an 11% sequential decrease. On a non-GAAP basis, gross margin was 45%, operating expenses were 26.7% of revenue, and operating income was 18.3% of revenue. GAAP gross margin was 43.3%, negatively impacted by reciprocal tariffs and product mix shifts compared to the prior quarter's tariff refund benefits.

• Q4 2026 Revenue: Guided between $225 million and $255 million, including ~$51.2 million of Safe Harbor revenue.
• Battery Shipments: Expected to be 100–120 MWh.
• Margins: GAAP gross margin guided at 38–41%; Non-GAAP gross margin guided at 40–43%. Both include ~2 percentage points of reciprocal tariff impact.
• Operating Expenses: GAAP opex guided at $119–$123 million; Non-GAAP opex guided at $76–$80 million.
• Outlook Commentary: Management anticipates a 10% sequential decline in global sell-through in Q4 ($20M drop) and plans to undership by ~$20M to reduce channel inventory. No specific guidance provided for 2027 full-year results, though core revenue is estimated at ~$200M/quarter excluding new growth drivers.

• Macroeconomic Headwinds: High interest rates are suppressing U.S. residential solar demand and permits, leading to a 35% YoY decline in sell-through.
• Regulatory Uncertainty: Delays in Treasury Department FIOC guidance and the expiry of the 25D tax credit have created visibility issues and reduced cash/loan market participation.
• Market Transition Risks: The transition from solar-only to solar-plus-battery systems requires significant installer and homeowner education; adoption in key markets like the Netherlands may lag until electricity bills rise in 2027.
• Execution Risk: New business lines (IQSST for data centers, bidirectional EV charging, and commercial storage) involve long development cycles, regulatory compliance (UL standards), and unproven large-scale manufacturing ramp-ups.
• Competitive Pressure: The battery market is highly competitive, requiring aggressive pricing and cost reductions (via Gen 5 battery) to maintain margins and market share.

Q: Brian Lee (Goldman Sachs) asked about the Q4 revenue implication of the stated $20M undershipment strategy and how this impacts the baseline outlook for 2027 given seasonal factors. / A: CEO Badri Kothandaraman clarified that global sell-through is expected to drop ~10% to ~$210M in Q4. To manage channel inventory ahead of slow Q1 seasonality, Enphase will undership by $20M, resulting in ~$190M into the channel. For 2027, he outlined a framework where core revenue remains ~$200M/quarter, supplemented by ~$200M in new growth drivers (battery volume increase, commercial growth, EV charging, etc.), though no formal 2027 guidance was provided.

Q: Philip Shen (Roth Capital) inquired about the potential downside risk to the $200M quarterly baseline if the U.S. residential market continues to weaken, asking if management sees risks to their core assumptions. / A: Kothandaraman acknowledged current weakness due to interest rates and unclear FIOC guidance, making 2027 difficult to predict. He emphasized that Enphase is diversifying away from reliance on residential solar recovery through five independent growth drivers: battery market share gains via Gen 5, Propel lease originations growing to 300+/week, commercial solar/storage resilience, EV charging partnerships, and AI data center entry. These vectors are designed to drive growth regardless of residential market conditions.

Q: Eric Stine (Craig Hallum) sought clarification on whether the optimism regarding storage growth had changed since the previous quarter, specifically questioning if France was the primary culprit for recent weakness. / A: Kothandaraman confirmed that short-term U.S. weakness persists due to interest rates, justifying conservative battery shipment guidance (100-120 MWh). However, he maintained strong optimism for long-term opportunities, particularly in the Netherlands (where net metering ends in 2026) and France. He noted that French activations are transitioning from pure solar to solar-plus-battery as feed-in tariffs disappear, creating a new opportunity for integrated energy management systems.

Q: Mark Strouse (J.P. Morgan) asked for more color on the $1 billion revenue potential for IQSST (solid-state transformers) by 2030, requesting to know if this was a top-down or bottom-up estimate. / A: CPO Raghu Belur explained that the estimate is based on conversations with hyperscalers who indicated market sizes ranging from 11 to 30+ gigawatts by 2030. Enphase assumes a reasonable market share and pricing structure within this addressable market. Belur highlighted that the technology uses GaN-based power modules, offering high efficiency, reliability, and modularity, with 85% supply chain overlap with existing microinverters, ensuring FIAC compliance and U.S. manufacturing readiness.

Q: Corinne Blanchard (Deutsche Bank) asked about the impact of midterm elections on tax credit extensions and whether this would influence Enphase’s U.S. manufacturing footprint strategy. / A: Raghu Belur noted there is bipartisan discussion supporting the extension of Investment Tax Credits (ITC) and Production Tax Credits (PTC), which would benefit renewables. Regarding manufacturing, CEO Badri Kothandaraman stated that Enphase has sufficient capacity in its U.S. facilities to scale for new products like IQSST without hesitation, indicating no immediate need to alter the footprint based on political outcomes, as current infrastructure supports future growth.
