3 min read

Q1 revenue of $282.9 million was impacted by a 23% sequential decline in the U.S. market, driven by the expiration of 2025 tax credits and typical seasonality.
Management attributed a 48% sequential drop in U.S. sell-through to a significant demand pull-forward in Q4 ahead of policy changes, though year-over-year sell-through declined a more modest 18%.
European revenue grew 36% sequentially as shipments aligned with sell-through levels, with April showing ‘green shoots’ in solar and battery activations across the Netherlands, France, and Germany.
The company is pivoting toward a battery-first strategy in Europe to counter intense competition from low-cost string inverters, noting that winning the battery relationship secures the broader home energy system.
U.S. commercial microinverter sales more than doubled sequentially, fueled by the adoption of the IQ9 GaN-based architecture which opened the 480V 3-phase market segment.
Operational focus has shifted toward the ‘long tail’ of installers through the Propel prepaid lease program, which aims to restore consumer economics to pre-tax credit expiration levels.
Management restructured the organization in Q1 to fund the new IQ Solid State Transformer (SST) program for AI data centers within the existing operating expense framework.

Q2 revenue guidance of $280 million to $310 million includes $85 million in safe harbor revenue and assumes under-shipping end-market demand by $25 million to correct Q1 channel inventory.
The Propel pilot is expected to expand beyond its current four-state footprint in July, targeting a run rate of 500 net originations per week by the end of 2024.
Fifth-generation AC-coupled batteries, featuring 50% higher energy density and 40% lower internal costs, are scheduled for pilot testing in Q3 and volume shipping in Q4.
The IQ SST for AI data centers targets a 2028 volume shipment timeline, aiming to eliminate site-car batteries by converting medium-voltage AC directly to 800V DC.
Management expects higher battery sales volumes in the second half of 2026 following price reductions of 10% in Europe and 12-14% in the U.S. enabled by reduced reciprocal tariff rates.

GAAP gross margin of 35.5% was negatively impacted by 6.7 percentage points due to the sale of 2025 Production Tax Credits (PTCs) at 93% of their value.
The company settled $632.5 million in outstanding principal for 5-year convertible notes using cash on hand during the quarter.
Management has submitted claims for approximately $50 million in tariff refunds following a U.S. Supreme Court ruling, with expected receipt within 90 to 120 days.
Q1 and Q2 sell-through expectations were revised 10% to 15% lower than previous internal views due to unfavorable weather and TPO financing challenges.
