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.

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.
| Metric | FY2020 | FY2021 | FY2022 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|---|---|
| Total Revenue | $774M | $1,382M | $2,331M | $2,291M | $1,330M | $1,473M |
| YoY Growth | — | 78.5% | 68.7% | -1.7% | -41.9% | 10.7% |

| Total OpEx | $160M | $339M | $526M | $613M | $552M | $529M |
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 $270-300M -- a further decline management views as
the cycle trough.
| Metric | Q1 24 | Q2 24 | Q3 24 | Q4 24 | Q1 25 | Q2 25 | Q3 25 | Q4 25 |
|---|---|---|---|---|---|---|---|---|
| Revenue ($M) | $263M | $303M | $381M | $383M | $356M | $363M | $410M | $343M |

| GAAP GM | 43.9% | 45.2% | 46.8% | 51.8% | 47.2% | 46.9% | 47.8% | 44.3% |
| Non-GAAP GM | 46.2% | 47.1% | 48.1% | 53.2% | 48.9% | 48.6% | 49.2% | 46.1% |
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.
| Metric | FY2020 | FY2021 | FY2022 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|---|---|
| GAAP Gross Margin | 44.7% | 40.1% | 41.8% | 46.2% | 47.3% | 46.6% |
| Non-GAAP Gross Margin | 40.1% | 40.7% | 42.6% | 47.1% | 48.9% | 48.2% |
| Net Income | $134M | $145M | $397M | $439M | $103M | $172M |
| GAAP EPS | $0.9 | $1.0 | $2.8 | $3.1 | $0.8 | $1.3 |
| Non-GAAP EPS | $1.4 | $2.4 | $4.6 | $4.4 | $2.4 | $3.0 |
Non-GAAP GM excludes stock-based compensation. GM ex-IRA production tax credit was ~38-39% in 2025. Q1 2026 guided at 42-45% non-GAAP GM with ~5% tariff headwind. Data from Daloopa and ENPH filings.
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.
| Metric | FY2020 | FY2021 | FY2022 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|---|---|
| Operating CF | $216M | $352M | $745M | $697M | $514M | $137M |
| Free Cash Flow | $199M | $315M | $698M | $586M | $480M | $96M |
| Shares (M) | 129.0M | 133.9M | 136.5M | 135.8M | 132.5M | 131.1M |
PTC receivables of $337M on balance sheet with IRS processing delays. $632.5M convertible note matured March 2026. Data from Daloopa and ENPH 10-K filings.
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.
