Business Overview
We are a global energy technology company. We deliver smart, easy-to-use solutions that manage solar generation, storage and communication on one platform. Our intelligent microinverters work with virtually every solar panel made, and when paired with our smart technology, result in one of the industry's best-performing clean energy systems. As of June 30, 2025, we have shipped approximately 83.1 million microinverters, and more than 4.9 million Enphase residential and commercial systems have been deployed in over 160 countries.
The Enphase® Energy System™, powered by IQ® Microinverters and IQ® Batteries, our current generation integrated solar, storage and energy management offering, enables self-consumption and delivers our core value proposition of yielding more energy, simplifying design and installation and improving system uptime and reliability. The IQ family of microinverters, like all of our previous microinverters, is fully compliant with NEC 2014 and 2017 rapid shutdown requirements. Unlike string inverters, this capability is built-in, with no additional equipment necessary.
The Enphase Energy System brings a high technology, networked approach to solar generation plus energy storage, by leveraging our design expertise across power electronics, semiconductors and cloud-based software technologies. Our integrated approach to energy solutions maximizes a home's energy potential while providing advanced monitoring and remote maintenance capabilities. The Enphase Energy System with IQ uses a single technology platform for seamless management of the whole solution, enabling rapid commissioning with the Enphase® Installer App and consumption monitoring with IQ® Gateway with IQ® Combiner+, Enphase® App, a cloud-based energy management platform, and our IQ Battery. System owners can use the Enphase App to monitor their home's solar generation, energy storage and consumption from any web-enabled device. Unlike some of our competitors, who utilize a traditional inverter, or offer separate components of solutions, we have built-in system redundancy in both photovoltaic generation and energy storage, eliminating the risk that comes with a single point of failure. Further, the nature of our cloud-based, monitored system allows for remote firmware and software updates, enabling cost-effective remote maintenance and ongoing utility compliance.
Enphase Energy, Inc. | 2025 Form 10-Q | 30
We sell primarily to solar distributors who combine our products with others, including solar module products and racking systems, and resell to installers in each target region. In addition to our solar distributors, we sell directly to select large installers, original equipment manufacturers ("OEMs") and strategic partners. Our OEM customers include solar module manufacturers who integrate our microinverters with their solar module products and resell to both distributors and installers. Strategic partners include providers of solar financing solutions. We also sell certain products and services to homeowners primarily in support of our warranty services and legacy product upgrade programs, via our online store.
Events Affecting our Business and Operations
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, 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.
One Big Beautiful Bill Act of 2025. In July 2025, the One Big Beautiful Bill Act of 2025 (the "OBBB") was enacted, introducing material changes to clean energy tax credit programs that are significant to our business and may impact our financial condition, results of operations and future prospects.
The OBBB scales back the Investment Tax Credit (the "ITC") available under Section 25D of the Internal Revenue Code (the "Code") for residential solar and storage systems purchased through cash or loans. Under the new law, the Section 25D credit will expire on December 31, 2025. In addition, the OBBB imposes new timing requirements for eligibility under Section 48E of the Code, which governs ITCs for leased solar and storage systems. Specifically, solar-only projects that do not commence construction within 12 months of the OBBB's enactment must be placed in service by December 31, 2027 in order to remain eligible for the credit. Energy storage projects are not subject to this placed-in-service deadline; however, the ITC for storage systems will begin to phase down in 2034 - decreasing to 75% in 2034, 50% in 2035 and phasing out entirely by 2036.
The OBBB also amends the domestic content bonus credit rules for Section 48E projects. Projects commencing construction after June 16, 2025 must meet a 45% domestic cost threshold, up from 40%.
Additionally, the OBBB introduces new compliance requirements under the Foreign Entity of Concern ("FEOC") provisions for both Section 48E and the Advanced Manufacturing Production Tax Credit ("AMPTC") under Section 45X. These provisions establish an escalating threshold of non-FEOC content that must be met by solar and storage projects beginning construction in 2026 and by manufactured components produced beginning in 2026.
On July 7, 2025, the President issued an Executive Order directing the Secretary of the Treasury to issue updated guidance within 45 days on the "beginning of construction" requirements applicable to Section 48E projects. The Executive Order also requires the Secretary to implement the FEOC restrictions set forth in the OBBB.
These legislative and regulatory developments may negatively impact our eligibility for certain tax credits, the attractiveness of our offerings to solar and storage system lease providers, and the overall demand for our products. If we are unable to meet the revised domestic content or FEOC requirements, our ability to qualify for these incentives could be impaired, which may adversely affect our revenue, gross margins, business operations and competitive position.
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.
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.
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.
Enphase Energy, Inc. | 2025 Form 10-Q | 31
Demand for Products.The demand environment for our products remained challenged during the first half of 2025, following a broad-based slowdown that began 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.

Interest income of $14.9 million decreased in the three months ended June 30, 2025, as compared to $19.2 million in the three months ended June 30, 2024, primarily due to lower average cash balance and lower interest rates.

Three months ended June 30, 2025 and 2024
The income tax provision was $5.2 million in the three months ended June 30, 2025, as compared to an income tax provision of $0.4 million in the same period in 2024. The increase was primarily due to higher projected tax expense as our operations in U.S. and foreign jurisdictions were more profitable in 2025, and an increase in tax expense from equity compensation shortfalls in 2025, as compared to the same period in 2024.
Six months ended June 30, 2025 and 2024
The income tax provision was $22.3 million in the six months ended June 30, 2025, as compared to an income tax provision of $5.0 million in the same period in 2024. The increase was primarily due to higher projected tax expense as our operations in U.S. and foreign jurisdictions were more profitable in 2025, an increase in tax expense from equity compensation shortfalls in 2025, and prior year true up adjustments in 2025, as compared to the same period in 2024.
Liquidity and Capital Resources
Sources of Liquidity
As of June 30, 2025, we had $1.1 billion in net working capital, including cash, cash equivalents and marketable securities of approximately $1.5 billion, of which approximately $1.4 billion were held in the United States. Our cash, cash equivalents and marketable securities primarily consist of U.S. Government agency securities and treasuries, money market mutual funds, corporate notes, commercial paper and bonds, and both interest-bearing and non-interest-bearing deposits, with the remainder held in various foreign subsidiaries. We consider amounts held outside the United States to be accessible and have provided for the estimated withholding tax liability on the repatriation of our foreign earnings.

Our cash, cash equivalents and marketable securities decreased by $116.2 million for the six months ended June 30, 2025, as compared to the same period in 2024, primarily due to repurchases of common stock pursuant to our share repurchase program, payout of the Notes due 2025, and payments of withholding taxes related to net share settlement of equity awards, partially offset by cash generated from operations.
Total carrying amount of debt decreased by $95.3 million for the six months ended June 30, 2025, as compared to the same period in 2024, primarily due to the payout of the Notes due 2025, partially offset by accretion of issuance costs.
We expect that our principal short-term (over the next 12 months) cash needs related to our operations will be to fund working capital, strategic investments, acquisitions, repurchases of common stock and payments of withholding taxes for net share settlement of employee equity awards, payments on our outstanding debt and purchases of property and equipment. We plan to fund any cash requirements for the next 12 months from our existing cash, cash equivalents and marketable securities on hand, and cash generated from operations. For the long-term period (beyond 12 months), we aim to continue growing cash flows from operations to support our ongoing business operations and strategic investment plans. We regularly evaluate our liquidity position, debt obligations and expected cash requirements. As part of this ongoing assessment, we may pursue additional financing through the issuance of equity or the debt financing, as necessary, to meet our operational and investment needs. We anticipate that access to the debt market will be more limited compared to prior years due to policy

changes to solar tax incentives from the enactment of the OBBB and high interest rates. 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.
Repurchase of Common Stock. In July 2023, the board of directors authorized a share repurchase program (the "2023 Repurchase Program") pursuant to which we were authorized to repurchase up to $1.0 billion of our common stock. The repurchases could be funded from available working capital and could be executed from time to time, subject to general business and market conditions and other investment opportunities, through open market purchases or privately negotiated transactions, including through Rule 10b5-1 plans. The 2023 Repurchase Program may be discontinued or amended at any time and expires on July 26, 2026. During the three months ended June 30, 2025, we repurchased 702,948 shares, for an aggregate amount of $30.0 million. As of June 30, 2025, we had approximately $268.7 million remaining for repurchase of shares under the 2023 Repurchase Program. For more information on the 2023 Repurchase Program, refer to Note 11. "Stockholders' Equity," of the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Convertible Notes. As of June 30, 2025, our aggregate principal convertible notes obligations were $1,207.5 million, which primarily consisted of the Notes due 2026 of $632.5 million and Notes due 2028 of $575.0 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. For more information on our convertible notes, refer to Note 9. "Debt," of the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Net cash provided by operating activities decreased by $101.2 million for the six months ended June 30, 2025, as compared to the same period in 2024, primarily driven by $110.3 million of microinverter shipments in the six months ended June 30, 2025 that are associated with orders that were prepaid in December 2024 for products delivered in the first half of 2025.

Contractual Obligations
Our contractual obligations primarily consist of the Notes due 2028 and Notes due 2026, obligations under operating leases and inventory component purchases. As of June 30, 2025, there have been no material changes from our disclosure in the Form 10-K, except that (i) we settled all of our outstanding Notes due 2025 for $102.2 million in cash and (ii) the Notes due 2026 mature in less than a year and are now classified as Debt, current on the condensed consolidated balance sheet as of June 30, 2025. For more information on our future minimum operating leases and inventory component purchase obligations as of June 30, 2025, refer to Note 10, "Commitments and Contingencies - Purchase Obligations" and for more information on our notes and other related debt, refer to Note 9, "Debt" of the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Critical Accounting Policies
Our condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. 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 U.S. 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 the Form 10-K.
Adoption of New and Recently Issued Accounting Pronouncements
For a discussion of adoption of new accounting pronouncements, refer to Note 1, "Description of Business and Basis of Presentation - Summary of Significant Accounting Policies" of the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
