Enphase Q1 2026: Post-25D Air Pocket Confirmed, Safe-Harbor Bridges But Core Demand Weakens

What happened

Enphase reported Q1 2026 results within its guided ranges: revenue of approximately $285 million (including ~$35 million safe-harbor), gross margin ~41.5% (reflecting ~5 points of tariff headwind), and non-GAAP operating expenses of ~$79 million. Ex safe-harbor, core revenue fell to ~$250 million, confirming the post-Section 25D demand air pocket. The company settled its $632.5 million convertible notes due March 1 using cash, leaving ample liquidity but narrowing the balance sheet cushion. Management reiterated its target to step down quarterly opex to $70-75 million by Q3 2026, while the commercial microinverter ramp remains nascent. The results validate the cautious near-term outlook, with no visible catalyst for a near-term re-rating.

Implication

Enphase's Q1 results confirm the thesis: safe-harbor temporarily props revenue, but underlying demand is soft. The convertible note maturity was handled without drama, preserving liquidity. The next catalyst is Q3 opex step-down and ex-safe-harbor revenue stabilizing above $220M. Until then, the stock trades on hope of a post-25D recovery, which carries execution risk. We maintain our WAIT rating with attractive entry at $35.

Thesis delta

No shift; the Q1 print validates the base case of a demand air pocket and cost cuts underway. The key checkpoint remains Q3 2026 for opex and revenue stabilization. The bull case requires commercial shipments to materially contribute to revenue, which has not yet materialized.
