Financial Trends -- 5/10

ENPH financial trends score a moderate 5/10. Revenue is recovering from a severe 2023-2024 destocking trough, up +10.7% YoY in FY2025 to $1.47B, but remains 37% below the FY2022 peak of $2.33B. Non-GAAP gross margins held resilient at 46-49%, and non-GAAP EPS grew +25% YoY to $2.96. Battery shipments are a bright spot at +36% YoY. However, FCF collapsed 80% ($480M to $96M) due to trapped PTC receivables, international revenue is in structural decline (down 66% in 2 years), and YoY revenue growth decelerated sharply through 2025 -- from +35% in Q1 to -10% in Q4. Q1 2026 guidance of $270-300M signals a further step-down, with management calling it the cycle trough. Weight: 25%

Revenue Trajectory (Annual, USD M) -- Calendar FY
Revenue recovering from trough but far below peak -- $1.47B in FY2025 vs $2.33B in FY2022. US revenue recovered +27% YoY ($935M to $1,189M) but international collapsed 28% ($396M to $284M). The geographic mix has shifted dramatically: international was 36% of FY2023 revenue but only 19% in FY2025. Europe is structurally challenged by Netherlands net metering phaseout, France feed-in tariff cuts, and intense competition. Q1 2026 guided at $270-300M signals a further step-down before expected H2 2026 recovery.

Revenue peaked at $2.33B in FY2022. FY2025 recovery of +10.7% still leaves revenue 37% below peak. Q1 2026 guidance of $270-300M viewed as cycle trough. Data from Daloopa and ENPH 10-K filings.

Quarterly Revenue and YoY Growth
YoY growth decelerated sharply through 2025: +35.2% (Q1) to -10.4% (Q4). Revenue troughed at $263M in Q1 2024 (down 64% YoY), then recovered sequentially through Q4 2024. But 2025 showed decelerating comps: Q4 declined 10.4% YoY, reflecting the 25D tax credit expiry pull-forward reversal, intentional channel destocking, and European weakness (Q4 intl was only $39M, the lowest since early 2020). Q1 2026 guided at $270-300M -- a further decline management views as the cycle trough.

Q4 2025 international revenue of $39M is the lowest since early 2020. Q1 2026 guidance: $270-300M revenue, 42-45% non-GAAP gross margin. Data from Daloopa and ENPH earnings transcripts.

Geographic Revenue: International Collapse
International revenue collapsed from $822M (FY2023) to $284M (FY2025) -- down 66% in 2 years. Europe is structurally challenged: Netherlands net metering phaseout, France feed-in tariff cuts, and intense pricing competition (price reductions implemented November 2025). Q4 2025 international was only $39M (11% of total), the lowest since early 2020. The battery retrofit opportunity (~475K Enphase solar homes in Netherlands + 375K in France = ~$2B TAM) is real but unproven.
International peaked at $822M in FY2023 (36% of total). Q4 2025 international of $39M is ~11% of quarterly revenue. Data from Daloopa and ENPH 10-K filings.

Profitability: Margins Resilient, EPS Recovering
Non-GAAP gross margins held at 46-49% through most of 2025, but Q4 dipped to 46.1% on tariffs. Tariff headwind of ~5% is expected to persist until Q2 2026 when non-China cell supply scales. GM excluding IRA production tax credits was only 38-39% in 2025 -- underlying profitability is weaker than the headline suggests. Q1 2026 guided at 42-45% non-GAAP GM, the lowest in 2+ years. FY2025 non-GAAP EPS of $2.96 was up 25% vs $2.37 in FY2024, but still 36% below FY2023 peak of $4.41. Quarterly non-GAAP EPS peaked at $0.94 in Q4 2024 and has not been matched since.

Free Cash Flow: Collapse from $480M to $96M
FCF collapsed from $480M (FY2024) to $96M (FY2025) -- down 80% despite revenue growth. Q3 2025 FCF was only $5.9M despite $410M revenue -- extremely poor conversion. Working capital drag from $337M in PTC receivables trapped on the balance sheet due to IRS processing delays. The $632.5M convertible note matured in March 2026, requiring cash deployment. Operating cash flow fell from $514M to $137M. The FCF profile is a significant red flag despite reported profitability.

Unit Shipments: Battery Growth is the Bright Spot
Battery shipments grew +36% YoY to 706 MWh -- the key growth lever. Record quarter was Q3 2025 at 195 MWh, though Q4 declined to 150 MWh. The 4th-gen IQ Battery 10C is gaining traction, and the 5th-gen battery (50% higher density, 40% lower cost) is expected in production Q4 2026. Battery retrofit opportunity in Europe (~$2B TAM) and attach rate expansion are key catalysts. Microinverter volumes recovered +38% YoY to 5.5M units, with Q3 2025 peak at 1.53M units.
Battery shipments: 351.6 MWh (FY2023), 521 MWh (FY2024), 706 MWh (FY2025). 5th-gen battery expected in production Q4 2026. Data from ENPH earnings transcripts.

Q1 2026 results
Q1 2026 guidance implies a further step-down, but management frames it as the cycle trough. Revenue of $270-300M would be down ~20% YoY and the lowest quarterly revenue since Q1 2024. Non-GAAP gross margin of 42-45% reflects persistent tariff headwinds (~5%) until non-China cell supply scales in Q2 2026. Key catalysts for H2 2026 recovery: (1) prepaid lease model replacing lost 25D economics, (2) IQ9 commercial expansion ($400M TAM, 50K+ units ordered for Q1 2026), (3) OpEx discipline targeting $70-75M/quarter by Q3 2026 (vs $79M today), and (4) potential interest rate relief driving loan-funded installations.
