How durable is the business?
Gross margin slightly contracted to 46.6% from 47.3% due to product mix and higher tariffs, though this was significantly offset by IRA tax credits (AMPTC). (2 contracting)
“Gross margin decreased by 0.7 percentage points in the year ended December 31, 2025, as compared to the same period in 2024. The decrease was primarily due to product mix and increased tariff costs”
International revenue continues to contract, dropping 15% year-over-year for the first half of 2025. This is attributed to persistent weak demand in Europe caused by changes in government policies and lower utility rates. (4 contracting)
“Net revenues from international markets were $49.0 million in the three months ended March 31, 2026, as compared to $92.8 million in the same period in 2025, a decrease of $43.9 million, or 47%, primarily driven by lower shipments to customers in Europe”
Enphase Energy is a global technology company that creates systems for homes and businesses to manage solar power, battery storage, and energy use on a single platform.
“Enphase Energy, Inc. (the “Company”) is a global energy technology company. The Company delivers smart, easy-to-use solutions that manage solar generation, storage and communication on one platform.”

What could break the thesis?
This risk has intensified with the enactment of the 'One Big Beautiful Bill Act' (OBBB) in July 2025, which officially repeals the Section 25D residential solar credit after 2025. (2 intensifying, 1 stable)
“a presidential proclamation was issued imposing a tariff surcharge of at least 10% under the balance of payments provision in Section 122 of the Trade Act of 1974 on all imports”
The balance sheet is stabilizing; while cash/securities decreased slightly by $116.2 million in the first half of 2025, the company maintains $1.5 billion in liquidity. (3 stable, 1 intensifying)
“Our cash, cash equivalents and marketable securities decreased by $601.2 million from March 31, 2025 to March 31, 2026, primarily due to payoff of the Notes due 2026, repurchases of common stock”
The risk remains high and stable as the company confirms it still relies exclusively on two Chinese vendors for LFP cells despite searching for alternatives. (4 stable)
“For example, lithium iron phosphate (“LFP”) battery cells used in our storage products are still supplied by two vendors located in China.”
Restructuring is intensifying as the company implemented a new '2024 Restructuring Plan' in Q4 2024, incurring $6.5 million in charges in the first half of 2025. (2 intensifying, 1 stable)
“In January 2026, the Company implemented a restructuring plan (the “2026 Restructuring Plan”) designed to better align its workforce and cost structure... Total restructuring and asset impairment charges $ 3,827”
Restructuring is intensifying as a new '2024 Restructuring Plan' was implemented, resulting in $7.8 million in charges for the first nine months of 2025. (1 intensifying)
“In the fourth quarter of 2024, the Company implemented a restructuring plan... designed to better align its workforce and cost structure with the Company’s business needs.”
