Current report
Trade Tariff Uncertainties. It is uncertain what impact new or existing tariffs, trade restrictions or retaliatory actions may have on us, the solar industry and our customers. We have relocated a significant portion of our contract manufacturing to the United States while continuing to utilize contract manufacturing in China and India. However, certain critical components for our products are still sourced from outside the United States.
Current report
For example, lithium iron phosphate ("LFP") battery cells used in our energy storage systems are currently supplied exclusively by two vendors located in China. While we are actively exploring alternative suppliers outside of China, the global supply chain for LFP battery cells remains heavily concentrated in China, and identifying qualified suppliers with the necessary expertise and capacity remains challenging.
Current report
An escalation in trade tensions or the implementation of broader tariffs, trade restrictions or retaliatory measures on our products or components originating from countries outside the United States could adversely impact our ability to source necessary components, manufacture products at competitive cost, or sell our products at prices customers are willing to pay. Any such developments could materially and adversely affect our business operations, results of operations and cash flows.
Current report

Net revenues from international geographical markets was $92.8 million in the three months ended March 31, 2025, as compared to $113.4 million in the same period in 2024, a decrease of $20.5 million, or 18%, primarily driven by continued softening in demand from customers in Europe, which was impacted by changes in government policies and lower utility rates.
Current report
Convertible Notes. As of March 31, 2025, our aggregate principal convertible notes obligations were $1,207.5 million, which primarily consisted of the Notes due 2028 of $575.0 million and Notes due 2026 of $632.5 million. Upon conversion of the Notes due 2026 and Notes due 2028, we expect to pay cash equal to the aggregate principal amount of the Notes of such series to be converted, and, at our election, will pay or deliver cash and/or shares of our common stock for the amount of our conversion obligation in excess of the aggregate principal amount of the Notes of such series. These conversions will be settled in a combination settlement method with the principal value settled in cash and the remaining value in shares of our common stock.

Previous report
Net revenues decreased by $1.0 billion, or 52%, in the nine months ended September 30, 2024, as compared to the same period in 2023, driven primarily by a 68% decrease in microinverter units shipped, partially offset by an increase in ASP for our microinverters as we sold more IQ8 microinverters relative to IQ7 microinverters. During the nine months ended September 30, 2024, we sold approximately 4.5 million microinverter units, as compared to approximately 13.9 million microinverter units in the nine months ended September 30, 2023. The decrease in net revenues was also partially offset by a 36% increase in IQ Batteries MWh shipped. During the nine months ended September 30, 2024, we shipped 368.6 MWh of IQ Batteries, as compared to 270.9 MWh shipped in the nine months ended September 30, 2023.
Previous report
Gross margin decreased by 0.7 percentage points in the three months ended September 30, 2024, as compared to the same period in 2023. The decrease was primarily due to product mix, relatively higher fixed overhead costs and a $4.6 million higher warranty expense for changes in estimates in the three months ended September 30, 2024, as compared to a $2.0 million lower warranty expense for changes in estimates in the three months ended September 30, 2023, partially offset by the recognition of a 9.2 percentage point Net IRA benefit in the three months ended September 30, 2024, as compared to a 2.6 percentage point Net IRA benefit in the three months ended September 30, 2023, and an increase in ASP for microinverters.
Previous report
Cost of revenues decreased by $559.7 million, or 52%, in the nine months ended September 30, 2024, as compared to the same period in 2023, primarily due to the lower volume of microinverter units, as well as from the benefit recognized from tax credits of $89.5 million in the nine months ended September 30, 2024, as compared to $20.6 million in the same period in 2023, under the AMPTC for U.S. manufactured microinverters shipped to customers. The benefit recognized from the AMPTC was partially offset by $22.2 million and $4.5 million of incremental cost for manufacturing in the United States in the nine months ended September 30, 2024 and September 30, 2023, respectively, thereby providing a Net IRA benefit of $67.3 million and $16.1 million, respectively.
Previous report
Research and development expense decreased by $7.0 million, or 13%, in the three months ended September 30, 2024, as compared to the same period in 2023. The decrease was primarily due to actions implemented in connection with the 2023 Restructuring Plan (as defined below) that lowered personnel-related expenses by $4.0 million due to a reduction in headcount and equipment, and professional services costs by $3.0 million. In the fourth quarter of 2023, we implemented a restructuring plan (the “2023 Restructuring Plan”) designed to increase operational efficiencies and execution, reduce operating costs, and better align our workforce and cost structure with current market conditions, and our business needs, strategic priorities and ongoing commitment to profitable growth. The amount of research and development expenses may fluctuate from period to period due to the differing levels and stages of development activity for our products.
Previous report
Sales and marketing expense decreased by $23.6 million, or 13%, in the nine months ended September 30, 2024, as compared to the same period in 2023.

Factors Affecting our Business and Operations
Current wording
Global Events Affecting our Business and Operations
Previous wording
As we have a growing global footprint, we are subject to risk and exposure from the evolving macroeconomic environment, including the effects of increased global inflationary pressures, tariffs and interest rates, fluctuations in foreign currency exchange rates, potential economic slowdowns or recessions, geopolitical pressures and potential regulatory changes through future legislative action or by a new presidential administration, including the unknown impacts of current and future trade regulations. We continuously monitor the direct and indirect impacts of these circumstances on our business and financial results.

We continuously monitor the direct and indirect impacts of these circumstances on our business and financial results.
Previous wording
Demand for Products. The demand environment for our products experienced a broad-based slowdown beginning in the second quarter of 2023 in the United States and in the third quarter of 2023 in Europe that continued into 2024. This demand environment has negatively impacted several distributors and installers, resulting in reduced liquidity, bankruptcy and business closures, which has affected our revenue and profitability, days sales outstanding and allowances for doubtful accounts. The slower demand environment also resulted in elevated inventory with distributors and installers in past quarters, and as a result we sold fewer microinverters to distributors and installers during the nine months ended September 30, 2024 compared to the same period in 2023 in response to this slower demand environment.
Current wording
Demand for Products. The demand environment for our products remained challenged during the three months ended March 31, 2025, following a broad-based slowdown beginning in the second quarter of 2023 in the United States and in the third quarter of 2023 in Europe. This prolonged softness in demand has continued to adversely impact certain distributors and installers, contributing to reduced liquidity, bankruptcies and business closures across the channel. These disruptions have negatively affected our revenue and profitability, and led to higher allowances for credit losses.
Previous wording
In the United States, this slowdown was primarily the result of higher interest rates and the transition from Net Energy Metering 2.0 (“NEM 2.0”) to Net Energy Metering 3.0 (“NEM 3.0”) in California, which has increased the payback period for our customers in California. In Europe, this slowdown was primarily the result of a decrease in purchases beginning in the third quarter of 2023 after the initial surge of sales related to onset of the armed conflict in Ukraine in 2022, and overall channel inventory correction. In addition, there has been increased uncertainty in net energy metering policies and solar export penalties in a key European market. The phase out of net energy metering in that market was ultimately not approved but solar export penalties are still causing uncertainty among consumers. While we believe we have made the appropriate corrections to our channel inventory, some of the foregoing trends in the United States and Europe could continue to have an adverse effect on our results of operations in the fourth quarter of 2024.
Current wording
In the United States, this slowdown was primarily the result of higher interest rates, high channel inventory and the transition from NEM 2.0 to NEM 3.0 in California. Higher interest rates resulted in larger monthly costs and longer pay-back periods for those customers who financed their systems. In Europe, this slowdown was primarily driven by a softer customer demand as utility rates dropped and policy changes were implemented. This resulted in oversupply, financial stresses throughout the industry and the resulting channel inventory correction. In addition, there has been increased uncertainty in NEM policies and solar export penalties in a key European market. The phase out of NEM in that market was ultimately not approved but solar export penalties are still causing uncertainty among consumers. While we believe we have made the appropriate corrections to our channel inventory, some of the foregoing trends in the United States and Europe could continue to have an adverse effect on our results of operations in 2025.

Previous wording
Cost of revenues decreased by $86.4 million, or 30%, in the three months ended September 30, 2024, as compared to the same period in 2023, primarily due to the lower volume of microinverter units shipped, as well as from the benefit recognized from tax credits of $46.6 million in the three months ended September 30, 2024, as compared to $18.5 million in the same period in 2023, under the Advanced Manufacturing Production Tax Credit (“AMPTC”) enacted under the IRA for U.S. manufactured microinverters shipped to customers. The benefit recognized from the AMPTC was partially offset by $11.4 million and $4.1 million of incremental cost for manufacturing in the United States in the three months ended September 30, 2024 and September 30, 2023, respectively, thereby providing a net benefit of $35.2 million and $14.4 million, respectively (“Net IRA benefit”).
Current wording
Cost of revenues increased by $40.0 million, or 27%, for the three months ended March 31, 2025, as compared to the same period in 2024. This increase was primarily driven by a higher volume of microinverter units sold and increased MWh of IQ Batteries shipped. This increase also included $15.7 million of incremental costs for manufacturing in the United States during the three months ended March 31, 2025, as compared to $4.9 million for the same period in 2024. This increase in cost of revenues was partially offset by benefits recognized from tax credits under the Advanced Manufacturing Production Tax Credit (“AMPTC”) for U.S. manufactured microinverters and IQ Batteries MW shipped to customers. The AMPTC benefits recognized were $53.6 million for the three months ended March 31, 2025, as compared to $18.6 million for the same period in 2024, resulting in a net IRA benefit of $37.9 million and $13.7 million, respectively.
Previous wording
Gross margin decreased by 0.4 percentage points in the nine months ended September 30, 2024, as compared to the same period in 2023. The decrease was primarily due to product mix and relatively higher fixed overhead costs, partially offset by the recognition of a 7.1 percentage point Net IRA benefit in the nine months ended September 30, 2024, as compared to a 0.8 percentage point Net IRA benefit in the same period in 2023, and an increase in ASP for microinverters.
Current wording
Gross margin increased by 3.3 percentage points in the three months ended March 31, 2025, as compared to the same period in 2024. The increase was primarily due to recognition of a 10.6 percentage point net IRA benefit in the three months ended March 31, 2025, as compared to a 5.2 percentage point net IRA benefit in the same period in 2024, partially offset by product mix and higher warranty expense from changes in estimates for an increase in tariff costs on product replacements.
Previous wording

General and administrative expense decreased by $1.1 million, or 3%, in the three months ended March 31, 2025, as compared to the same period in 2024. The decrease was primarily due to actions implemented in connection with the restructuring initiatives implemented in 2024 that lowered personnel-related costs by $1.6 million due to a reduction in headcount offset by an increase in professional services and facilities expense by $0.5 million.

We expect that our principal short-term (over the next 12 months) and long-term cash needs related to our operations will be to fund working capital, strategic investments, acquisitions, repurchases of common stock pursuant to our share repurchase program and payments of withholding taxes for net share settlement of equity awards, payments on our outstanding debt and the purchases of property and equipment. We plan to fund any cash requirements for the next 12 months and the longer term from our existing cash, cash equivalents and marketable securities on hand, and cash generated from operations. We anticipate that access to the debt market will be more limited compared to prior years as interest rates have increased and are expected to remain high. Our ability to obtain debt or any other additional financing that we may choose to, or need to, obtain will depend on, among other things, our development efforts, business plans, operating performance and the condition of the capital markets at the time we seek financing.

Our condensed consolidated financial statements are prepared in accordance with Generally Accepted Accounting Principles (“GAAP”). In connection with the preparation of our condensed consolidated financial statements, we are required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our condensed consolidated financial statements are prepared. On a regular basis, we review the accounting policies, assumptions, estimates and judgments to ensure that our condensed consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

We consider an accounting policy to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the condensed consolidated financial statements. There have been no changes to our critical accounting policies as described in our Form 10-K for the year ended December 31, 2023.

The overall decrease in net revenues during both the three and nine months ended September 30, 2024, as compared to the same periods in 2023 was due to a broad-based slowdown that began in the second quarter of 2023 in the United States and the third quarter of 2023 in Europe that resulted in elevated inventory with distributors and installers, and as a result we sold fewer microinverters to distributors and installers during the nine months ended September 30, 2024, as compared to the same period in 2023. In the United States, this slowdown was primarily the result of higher interest rates, high channel inventory and the transition from NEM 2.0 to NEM 3.0 in California. Higher interest rates resulted in larger monthly costs and longer pay-back periods for those customers who financed their systems. In Europe, this slowdown was primarily driven by a softer customer demand as utility rates dropped, policy changes were implemented, and the impacts from the Ukraine war were felt to be less impactful. This resulted in oversupply, financial stresses throughout the industry and the resulting channel inventory correction.

The income tax provision was $10.0 million in the nine months ended September 30, 2024, as compared to an income tax provision of $82.9 million in the same period in 2023. The decrease was primarily due to lesser projected tax expense as our operations in U.S. and foreign jurisdictions were less profitable in 2024 as compared to the same period in 2023, and tax expense from equity compensation shortfalls, partially offset by a discrete tax benefit from the impairment of an investment in a private company.
