    Our Company
    We are a global energy technology company originally founded in March 2006. 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.
    For the first time in the evolution of our centuries-old grid, people can get paid for the clean energy they produce and share with their communities, helping to build a new energy future that harnesses the sun. This clean, free, abundant source of energy can power our lives and ultimately help greatly reduce our dependence on fossil fuels. As of December 31, 2025, we have shipped approximately 86.4 million microinverters, and more than 5.1 million Enphase residential and commercial systems have been deployed in over 160 countries.
    We design, develop, manufacture and sell home energy solutions that manage energy generation, energy storage, and control and communications on one intelligent platform. We have revolutionized the solar industry by bringing a systems approach to solar technology and by pioneering a semiconductor-based microinverter that converts energy at the individual solar module level and, combined with our proprietary networking and software technologies, provides advanced energy monitoring and control. This is vastly different than a string inverter system using string modules, whether with or without an optimizer, which only converts the energy of the entire array of solar modules from a single high voltage electrical unit and lacks intelligence about the energy producing capacity of the solar array.
    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 uses a single technology platform for seamless management of the whole solution, of IQ® Microinverters, IQ® Batteries, IQ® Load Controllers, and IQ® EV Charger, allowing rapid commissioning with the Enphase® Installer App, consumption monitoring with our IQ® Combiner™ device with our Enphase IQ® Gateway™ device, and our Enphase® App, a cloud-based energy management platform. 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 (“PV”) 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.
    We have transitioned from solar only systems to complete energy management solutions, which consist of solar, batteries, load control, electrical vehicle (“EV”) charging, compatibility with third-party generators, and grid services. This transition follows the rising global interest in the full electrification of homes and businesses through renewable sources of energy.

    Enphase Energy, Inc. | 2026 Form 10-Q | 32

    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 a variety of companies, including industrial equipment suppliers, module companies, energy suppliers and developers of third-party solar finance offerings (such as TPOs). 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 military conflicts (including the Iran conflict), 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. In July 2025, the One Big Beautiful Bill Act (the “OBBBA”) 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 OBBBA scales back the Investment Tax Credit (the “ITC”) available under Section 25D of the Internal Revenue Code of 1986, as amended (the “Code”), for residential solar and storage systems purchased through cash or loans. Under the new law, the Section 25D credit expired on December 31, 2025. In addition, the OBBBA 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 did not commence construction within 12 months of the OBBBA’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 OBBBA 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 OBBBA introduces new compliance requirements under the FEOC provisions for both Section 48E of the Code and the Advanced Manufacturing Production Tax Credit (“AMPTC”) under Section 45X of the Code. 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.
    In August 2025, U.S. Treasury Department and the Internal Revenue Service (“IRS”) issued revised “beginning of construction” guidance for clean energy tax credits that only applies to Section 48E projects above 1 MW.
    In February 2026, the U.S. Treasury Department and the IRS issued guidance under the OBBBA’s FEOC provisions applicable to Sections 48E and 45X of the Code, including rules and interim safe harbors for determining whether projects or manufactured components receive material assistance from prohibited foreign entities. Treasury and the IRS have indicated that additional proposed regulations and safe harbor tables are expected, including guidance addressing ownership, effective control, debt, licensing arrangements and anti‑circumvention matters, which could make the compliance requirements more restrictive over time.
    These legislative and regulatory developments have impacted and may in the future negatively impact our eligibility for certain tax credits, the attractiveness of our offerings to solar and storage system lease providers, or 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.
    In March 2026, we entered into an agreement for the sale of $235.0 million of AMPTC we generated during 2025 at 93% of face value, resulting in a discount of approximately $16.5 million. We also incurred approximately $2.5 million in transaction-related fees.
    In June 2026, we entered into an agreement for the sale of up to $150.0 million of AMPTC we generated during 2026 at 93% of face value. Of such $150.0 million, in June 2026 we sold $37.5 million of AMPTC generated
    Enphase Energy, Inc. | 2026 Form 10-Q | 33

    in the first quarter of 2026 for approximately $34.9 million and incurred approximately $0.5 million in transaction-related fees.
    Trade Tariff Uncertainties. The impact of new or existing tariffs, trade restrictions or retaliatory actions on us, the solar industry and our customers continues to create uncertainty and adversely affect our business operations. On February 20, 2026, the United States Supreme Court issued a decision invalidating certain tariffs previously imposed under the International Emergency Economic Powers Act ("IEEPA"). Following this ruling, the U.S. Court of International Trade directed U.S. Customs and Border Protection (“CBP”) to establish a process for the submission and review of refund claims related to eligible IEEPA tariffs. On April 20, 2026, CBP launched an online portal through which companies may submit refund requests for eligible IEEPA tariffs. We received refunds and associated interest of approximately $41.0 million and $11.0 million in the three months ended June 30, 2026 and in July 2026, respectively, from CBP related to tariffs paid during fiscal 2025 and the first quarter of fiscal 2026, of which $45.4 million was recognized as a reduction to cost of revenues during the three and six months ended June 30, 2026, $1.6 million was recognized as interest income in the three and six months ended June 30, 2026, and $5.0 million was capitalized as a cost of inventory as of June 30, 2026.
    We have submitted additional refund claims for tariffs previously paid and continue to evaluate the recoverability of these amounts. As the approval and timing of such refunds remain uncertain and are contingent upon CBP’s review and validation process, we have not recognized a receivable as of June 30, 2026 and will not recognize such amounts until they are realized or realizable. The ultimate impact of any future approved refunds, if any, could be material.
    Furthermore, following the Supreme Court's decision, the Administration imposed a temporary import surcharge under Section 122 of the Trade Act of 1974 (“Section 122”). The surcharge was initially set at 10% ad valorem on all imports, and subsequently increased to 15%, the statutory maximum, with certain exceptions for specified commodities (e.g., electronics, critical minerals) and United States-Mexico-Canada Agreement qualified products. The surcharge took effect on February 24, 2026, for a maximum period of 150 days. On May 7, 2026, the U.S. Court of International Trade held that the Section 122 proclamation was invalid. The government has appealed the ruling, and the Federal Circuit issued a temporary stay pending appeal. On July 23, 2026, following an investigation initiated on June 2, 2026 under Section 301 of the Trade Act of 1974, the Administration announced new tariffs ranging from 10% to 12.5% on imports from 60 trading partners. These tariffs were announced shortly before the expiration of the Section 122 tariffs on July 24, 2026. The tariffs apply to many of the countries from whom we source materials and can include some products material to our business. The evolving legal status, and expiration of the Section 122 tariffs creates additional uncertainty regarding our tariff exposure and any potential recovery of Section 122 duties paid during the quarter. If the Section 122 proclamation is ultimately held invalid and refund mechanisms are established, we may be eligible to recover some or all of the Section 122 duties paid. However, the outcome of the appeal and the availability, timing and amount of any potential refunds remain uncertain and are subject to further judicial and administrative proceedings. No receivable for potential Section 122 tariff refunds has been recognized as of June 30, 2026.
    We have moved a significant portion of our 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 storage products are still supplied solely by two vendors located in China. Although we are in the process of searching for other vendors outside of China for future supplies, the expertise and industry for the LFP battery cell is primarily in China, and it will require significant effort to identify alternative, qualified suppliers with the right expertise to develop our battery cells.
    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.
    Safe Harbor Agreements. We executed agreements year-to-date through the safe harbor deadline with TPO customers for products totaling approximately $1,081.1 million, of which $202.4 million is under the ITC Five Percent Safe Harbor method and $878.6 million is under the Physical Work Test beginning-of-construction method. These arrangements are designed to support customers’ qualification for ITC and have become an increasingly important growth channel for U.S. residential solar and battery adoption following the expiration of the residential ITC under Section 25D of the Code on December 31, 2025.
    Enphase Energy, Inc. | 2026 Form 10-Q | 34

    As of June 30, 2026, contract liabilities included in deferred revenues, current and deferred revenues, non-current on the condensed consolidated balance sheet includes approximately $105.8 million prepayments or billings under the ITC Five Percent Safe Harbor method for products to be delivered in the third and fourth quarters of 2026, and approximately $45.6 million prepayments or billings under the Physical Work Test beginning-of-construction method. Product deliveries and revenue recognition associated with these arrangements may occur over multiple periods through the second quarter of 2031 and are dependent on the timing of product shipment and satisfaction of performance obligations. As a result, the timing and structure of these safe harbor arrangements have contributed to increased variability in the timing of revenue recognition and cash flows between reporting periods.
    Demand for Products. The prolonged softness in demand in the solar industry 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 could result in higher allowances for credit losses in the future. In Europe, the overall business environment across the region is still challenging, and is expected to remain constrained in 2026. In the United States, uncertainty related to changes in legislation, including from the OBBBA, which eliminated or reduced existing tax credits for clean energy programs, as well as evolving U.S. trade and tariff policies, may further contribute to market volatility and adversely impact customer demand for our products, pricing and our financial performance.

Delivering 7.1 kVA continuous output and 90 A of PowerStartTM capability per 10 kWh unit, the IQ Battery 10C is engineered to seamlessly support heavy household loads like HVAC units and pool pumps, without requiring additional neutral-forming hardware.
    We continue to expand the deployment of the IQ Battery 5P with FlexPhase™ technology, an AC-coupled, modular 5 kWh battery with 3.84 kVA of continuous power per unit, for both single-phase and three-phase applications. This product is currently shipping to Austria, Germany, Switzerland, Luxembourg, Poland, France, Spain, Portugal, the Netherlands, Greece, Romania, Croatia, Finland, Malta, Estonia, India, Belgium, Slovenia, Slovakia, Denmark, Latvia, Lithuania, Sweden, Hungary, Bulgaria, North Macedonia, and Australia. The standard IQ Battery 5P continues to ship in the United States, Cayman Islands, Australia, New Zealand, Puerto Rico, Mexico, Canada, the United Kingdom, Italy, France, the Netherlands, Luxembourg, Belgium, Romania and India. These Enphase IQ Batteries in Europe can be installed with both single-phase and three-phase third-party solar energy inverters, enabling homeowners to upgrade their existing home solar systems with a residential battery storage solution that reduces costs while providing increased self-reliance.
    Our older Enphase IQ Battery 3T and IQ Battery 10T storage systems, have a usable capacity of 10.1 kWh and 3.4 kWh for the United States, and 10.5 kWh and 3.5 kWh for Europe and other international countries. We currently ship these IQ Battery storage systems customers in the United States, Puerto Rico, Canada, Mexico, Australia, New Zealand, Belgium, Germany, the United Kingdom, Italy, Austria, France, the Netherlands, Luxembourg, Finland, Switzerland, Spain, Portugal, Sweden, Denmark and Greece.
    In October 2025, we announced support in the United States for complete off-grid system configurations that are capable of operating without a utility connection when needed. The system requires the IQ Battery 5P with embedded grid-forming microinverters, IQ8 Series Microinverters with Sunlight JumpStart™ technology and a third-party standby AC generator, which all work together to power the home.
    In December 2025, we launched our PowerMatch™ technology, a battery software upgrade in Europe. PowerMatch intelligently adjusts IQ Battery output to match a home’s real-time power needs by activating only the microinverters needed, delivering more usable energy, higher efficiency, longer battery life and greater long-term savings. The efficiency gains achieved with this technology can improve battery performance by as much as 40%. In May 2026, we expanded PowerMatch technology to North America, making it available to homeowners with qualifying IQ Battery systems in the United States and Canada.

        New Products in Development. In April 2026, we announced that we are developing our 1.25 MW IQ SST product for data centers, a distributed solid-state transformer platform designed to convert medium-voltage AC directly to low-voltage DC in a single stage. The IQ SST will be built as a supercluster of 342 power modules, with each module powered by our custom Kestrel ASIC and high-frequency GaN-based power platform. The architecture is designed to deliver native 800 V DC output for next-generation AI racks, fast response on the order of 1 to 3 milliseconds, built-in redundancy, and serviceability through hot-swappable modules. We expect full system demonstrations later this year.

    Three months ended June 30, 2026 and 2025
    Net revenues decreased by $71.3 million, or 20%, in the three months ended June 30, 2026, as compared to the same period in 2025, driven primarily by a 40% decrease in IQ Batteries MWh shipped and product price decreases, partially offset by a 4% increase in microinverter units sold. During the three months ended June 30, 2026, we sold approximately 1.6 million microinverter units and shipped 113.8 MWh of IQ Batteries, as compared to approximately 1.5 million microinverter units and 190.9 MWh of IQ Batteries shipped in the three months ended June 30, 2025.
    Net revenues in the United States were $226.9 million in the three months ended June 30, 2026, as compared to $271.3 million in the same period in 2025, a decrease of $44.4 million, or 16%, primarily due to the expiration of the federal residential clean energy tax credit under Section 25D of the Internal Revenue Code. Microinverter shipments that are associated with safe harbor transactions with customers were $84.3 million and $40.4 million in the three months ended June 30, 2026 and 2025, respectively.
    Net revenues from international markets were $65.0 million in the three months ended June 30, 2026, as compared to $91.8 million in the same period in 2025, a decrease of $26.8 million, or 29%, primarily driven by lower shipments to customers in Europe driven by continued softening in demand and delayed purchasing activity. In addition, demand in certain European markets was impacted by macroeconomic conditions, regulatory and incentive framework transitions, and lower electricity prices compared to the same period in 2025, which reduced near‑term installation activity and delayed project starts.
    Six months ended June 30, 2026 and 2025
    Net revenues decreased by $144.5 million, or 20%, in the six months ended June 30, 2026, as compared to the same period in 2025, driven primarily by a 40% decrease in IQ Batteries MWh shipped, 2% decrease in microinverter units sold and product price decreases.
