Enphase Energy Reports Financial Results for the First Quarter of 2024
FREMONT, Calif., April 23, 2024 - Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company and the world’s leading supplier of microinverter-based solar and battery systems, announced today financial results for the first quarter of 2024, which included the summary below from its President and CEO, Badri Kothandaraman.
We reported quarterly revenue of $263.3 million in the first quarter of 2024, along with 46.2% for non-GAAP gross margin. We shipped 1,382,195 microinverters, or approximately 603.6 megawatts DC, and 75.5 megawatt hours of IQ® Batteries.

Diluted EPS$(0.12)$0.15 $1.02 $0.35 $0.54 $1.37 

Total revenue for the first quarter of 2024 was $263.3 million, compared to $302.6 million in the fourth quarter of 2023. Our revenue in the United States for the first quarter of 2024 decreased approximately 34%, compared to the fourth quarter of 2023. Our revenue in Europe increased approximately 70%, compared to the fourth quarter of 2023. The decline in revenue for the first quarter of 2024 compared to the fourth quarter of 2023 was the result of seasonality and a further softening in U.S. demand, while we continued to reduce shipments to manage channel inventory.
Our non-GAAP gross margin was 46.2% in the first quarter of 2024, compared to 50.3% in the fourth quarter of 2023, primarily driven by lower net IRA benefit. Our non-GAAP gross margin, excluding net IRA benefit, was 41.0% in the first quarter of 2024, compared to 41.8% in the fourth quarter of 2023, primarily driven by lower volume. Our non-GAAP operating expenses were $82.6 million in the first quarter of 2024, compared to $86.6 million in the fourth quarter of 2023. Our non-GAAP operating income was $39.0 million in the first quarter of 2024, compared to $65.6 million in the fourth quarter of 2023.

We exited the first quarter of 2024 with $1.63 billion in cash, cash equivalents, and marketable securities and generated $49.2 million in cash flow from operations in the first quarter of 2024. Our capital expenditures were $7.4 million in the first quarter of 2024, compared to $20.1 million in the fourth quarter of 2023. Capital expenditure requirements decreased due to a reduction in our U.S. manufacturing spending.
In the first quarter of 2024, we repurchased 332,735 shares of our common stock at an average price of $126.21 per share for a total of approximately $42.0 million. We also spent approximately $60.0 million dollars by withholding shares to cover taxes for employee stock vesting and options in the first quarter of 2024 that reduced the diluted shares by 480,735 shares.
We are now shipping IQ8P Microinverters with peak output AC power of 480 W for the small-commercial market in North America, and grid-tied residential applications in South Africa, Mexico, Brazil, India, Thailand, the Philippines, France, and Spain. We currently ship IQ8 Microinverters into 24 countries worldwide.
We shipped 75.5 megawatt hours of IQ Batteries in the first quarter of 2024. We now ship our third generation of IQ Batteries, the IQ® Battery 5P, to the United States, Puerto Rico, Australia, the United Kingdom, and Italy. More than 4,900 installers worldwide are certified to install our IQ Batteries.
During the first quarter of 2024, we shipped approximately 506,000 microinverters from our contract manufacturing facilities in the United States that qualified for 45X production tax credits. Once fully ramped, we expect to have a global capacity of approximately 7.25 million microinverter units per quarter, of which 5 million units of capacity will be in the United States.

Use of non-GAAP Financial Measures
Enphase Energy has presented certain non-GAAP financial measures in this press release. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States (GAAP). Reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure can be found in the accompanying tables to this press release. Non-GAAP financial measures presented by Enphase Energy include non-GAAP gross profit, gross margin, operating expenses, income from operations, net income, net income per share (basic and diluted), net IRA benefit, and free cash flow.
These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Enphase Energy’s results of operations as determined in accordance with GAAP. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Enphase Energy uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. Enphase Energy believes that these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.
As presented in the “Reconciliation of Non-GAAP Financial Measures” tables below, each of the non-GAAP financial measures excludes one or more of the following items for purposes of calculating non-GAAP financial measures to facilitate an evaluation of Enphase Energy’s current operating performance and a comparison to its past operating performance:
3


Stock-based compensation expense. Enphase Energy excludes stock-based compensation expense from its non-GAAP measures primarily because they are non-cash in nature. Moreover, the impact of this expense is significantly affected by Enphase Energy’s stock price at the time of an award over which management has limited to no control.
Acquisition related expenses and amortization. This item represents expenses incurred related to Enphase Energy’s business acquisitions, which are non-recurring in nature, and amortization of acquired intangible assets, which is a non-cash expense. Acquisition related expenses and amortization of acquired intangible assets are not reflective of Enphase Energy’s ongoing financial performance.
Restructuring and asset impairment charges. Enphase Energy excludes restructuring and asset impairment charges due to the nature of the expenses being unusual and arising outside the ordinary course of continuing operations. These costs primarily consist of fees paid for cash-based severance costs and asset write-downs of property and equipment and acquired intangible assets, and other contract termination costs resulting from restructuring initiatives.
Non-cash interest expense. This item consists primarily of amortization of debt issuance costs and accretion of debt discount because these expenses do not represent a cash outflow for Enphase Energy except in the period the financing was secured and such amortization expense is not reflective of Enphase Energy’s ongoing financial performance.
Non-GAAP income tax adjustment. This item represents the amount adjusted to Enphase Energy’s GAAP tax provision or benefit to exclude the income tax effects of GAAP adjustments such as stock-based compensation, amortization of purchased intangibles, and other non-recurring items that are not reflective of Enphase Energy ongoing financial performance.
Non-GAAP net income per share, diluted. Enphase Energy excludes the dilutive effect of in-the-money portion of convertible senior notes as they are covered by convertible note hedge transactions that reduce potential dilution to our common stock upon conversion of the Notes due 2025, Notes due 2026, and Notes due 2028, and includes the dilutive effect of employee’s stock-based awards and the dilutive effect of warrants. Enphase Energy believes these adjustments provide useful supplemental information to the ongoing financial performance.
Net IRA benefit. This item represents the advanced manufacturing production tax credit (“AMPTC”) from the IRA for manufacturing microinverters in the United States, partially offset by the incremental manufacturing cost incurred in the United States relative to manufacturing in Mexico, India, and China. The AMPTC is accounted for by Enphase Energy as an income-based government grants that reduces cost of revenues in the consolidated statements of operations.
Free cash flow. This item represents net cash flows from operating activities less purchases of property and equipment.
