Total revenue increased 17%, compared to the third quarter of 2021. We were able to meet the surge in customer demand while successfully navigating supply constraints and logistics challenges. Strong demand for our IQ™ Microinverters continued in the fourth quarter of 2021, while shipments of our IQ Batteries increased approximately 53%, compared to the third quarter of 2021. Our non-GAAP gross margin was 40.2% in the fourth quarter of 2021, compared to 40.8% in the third quarter of 2021, primarily due to product mix.

Non-GAAP operating expenses increased to $68.2 million in the fourth quarter of 2021, compared to $57.3 million in the prior quarter, primarily due to additional investment in product launches, R&D, and IT infrastructure. Non-GAAP operating income was $97.7 million in the fourth quarter of 2021, compared to $85.9 million in the third quarter of 2021.

We exited the fourth quarter of 2021 with $1.0 billion in cash, cash equivalents and marketable securities and generated $97.2 million in cash flow from operations in the fourth quarter of 2021. Capital expenditures were $13.2 million in the fourth quarter of 2021, compared to $12.7 million in the third quarter of 2021.

We started production shipments of IQ8 Microinverters for customers in North America in the fourth quarter of 2021. IQ8 solar microinverters can form a microgrid during a power outage using only sunlight, providing backup power even without a battery. IQ8’s grid-forming technology eliminates traditional ratio requirements between solar system size and battery size. With IQ8, any home can adopt Enphase technology for backup, even with no battery or a small battery.

We completed the acquisition of ClipperCreek in the fourth quarter of 2021. Founded in 2006, ClipperCreek offers electric vehicle (EV) charging solutions for residential and commercial customers in the U.S. The increasing penetration of EVs has implications for home energy management. Homes will consume significantly more power with an EV and the large EV battery could be used for backup and grid services in the future. This acquisition will soon leverage our power conversion and software platform to manage loads and resources within the home.

We continued to make excellent progress on our installer digital platform. We acquired 365 Pronto, Inc. during the fourth quarter of 2021. The company offers a predictive software platform dedicated to simplifying maintenance by matching cleantech asset owners to a local and on-demand workforce of service providers. Our two prior acquisitions, which provide proposal software and permitting services for installers, continue to do well with new features slated for release this year.

For the full year 2021, revenue was $1,382.0 million, compared to $774.4 million in 2020. We generated a record $352.0 million in cash flow from operations in 2021, compared to $216.3 million in 2020. GAAP net income was $145.4 million, resulting in diluted earnings per share of $1.02. Non-GAAP net income was $340.3 million, resulting in Non-GAAP diluted earnings per share of $2.41.

BUSINESS HIGHLIGHTS

On Nov. 29, 2021 Enphase Energy announced that its microinverter-based solar systems are becoming increasingly preferred for commercial installations by government and community organizations in Australia seeking to offset daytime electricity costs and make progress towards net zero goals. Enphase’s distributed and all-AC architecture combined with panel-level monitoring ensures that Enphase microinverter-based solar systems are smart and safer choices for solar assets installed on commercial facilities.

On Dec. 2, 2021 Enphase Energy announced its participation in Arizona Public Service (APS) Residential Battery Pilot grid services program. The program offers homeowners with Enphase IQ Batteries in APS’s service territory two ways to participate and earn money through one-time, upfront incentives. More Arizonans than ever before will get to experience the benefits of Enphase solar and battery systems, while also helping to make the grid more reliable.

On Jan. 27, 2022, Enphase Energy and Semper Solaris, one of the nation’s leading home solar and battery contractors headquartered in California, announced a strategic partnership focused on deploying Enphase Energy Systems, powered by IQ Microinverters and IQ Batteries, across California. Enphase Energy Systems and the Enphase^® App give households enhanced control and flexibility, enabling them to optimize their home energy system around various rate structures through self-consumption, seamless participation in grid services programs, and the ability to go off-grid.

Enphase Energy recently announced that Enphase installers in Southern California, Washington, D.C. area, New York, Colorado, Illinois, Washington, Pennsylvania, Massachusetts, and Arizona have seen growing deployments of the Enphase Energy System powered by IQ Microinverters and IQ Batteries.

(1)	We sought refunds totaling approximately $38.9 million plus $0.6 million accrued interest on tariffs previously paid from September 24, 2018 to March 31, 2020 for certain microinverters that qualify for the tariff exclusion on Chinese imported microinverter products that fit the dimensions and weight limits within a Section 301 Tariff exclusion under U.S. note 20(ss)(40) to subchapter III of chapter 99 of the Harmonized Tariff Schedule of the United States. The refund request was subject to review and approval by the U.S. Customs and Border Protection; therefore, we assessed the probable loss recovery in the three and twelve months ended December 31, 2020 was equal to the $16.5 million and $39.5 million, respectively, approved refund requests available to us prior to the date our financial statements were expected to be issued. As of the three and twelve months ended December 31, 2020, we had recorded $15.9 million and $38.9 million, respectively as a reduction to cost of revenues, and $0.6 million as interest income, in our consolidated statements of operations as the approved refunds relate to paid tariffs previously recorded to cost of revenues.
(2)	Loss on partial settlement of convertible notes of $0.1 million for the three months ended December 31, 2021, primarily relates to the non-cash loss on settlement of $1.1 million remaining aggregate principal amount of the Notes due 2024. Loss on partial settlement of convertible notes of $56.5 million for the year ended December 31, 2021 primarily relates to the $9.6 million non-cash loss on settlement of $88.2 million remaining aggregate principal amount of the Notes due 2024, $9.5 million non-cash loss on partial settlement of $217.8 million aggregate principal amount of the Notes due 2025 and $37.5 million non-cash inducement loss incurred on repurchase of Notes due 2025. Loss on partial settlement of convertible notes of $3.0 million for the three and twelve months ended December 31, 2020 primarily relates to the non-cash loss on partial settlement of $43.9 million aggregate principal amount of the Notes due 2024.
(3)	Change in fair value of derivatives of $44.3 million for the year ended December 31, 2020, represents changes in fair value of the conversion option in the Notes due 2025, as well as the convertible note hedge and warrant transactions. Initially, conversion of the Notes due 2025 would be settled solely in cash as a result of the Company not having the necessary number of authorized but unissued shares of its common stock available to settle the conversion option of the Notes due 2025 in shares; therefore, the conversion option, convertible note hedge and warrant transactions were classified as derivatives that required marked-to-market accounting. On May 20, 2020, at the Company’s annual meeting of stockholders, the stockholders approved an amendment to its certificate of incorporation to increase the number of authorized shares of the Company’s common stock. As a result, the Company will now be able to settle the Notes due 2025, convertible notes hedge and warrants through payment or delivery, as the case may be, of cash, shares of its common stock or a combination thereof, at the Company’s election. Accordingly, on May 20, 2020, the conversion option, convertible note hedge and warrant transactions were remeasured at fair value and were then reclassified to additional paid-in-capital in the condensed consolidated balance sheet in the second quarter of 2020 and are no longer remeasured as long as they continue to meet the conditions for equity classification.
