Net income $ 21,809     $ 39,351     $ 39,362     $ 84,157     $ 74,676     $ 41,760  
Basic EPS $ 0.16     $ 0.29     $ 0.31     $ 0.62     $ 0.55     $ 0.33  
Diluted EPS $ 0.15     $ 0.28     $ 0.28     $ 0.60     $ 0.53     $ 0.30  

Total revenue increased 11% compared to the second quarter of 2021. We worked diligently to meet the surge in customer demand while successfully navigating global component supply constraints and logistics challenges.

Our non-GAAP gross margin was 40.8% in both the third and second quarter of 2021, as higher logistics and expedite costs were partially offset by a price increase on microinverters and cost management. Non-GAAP operating expenses increased to $57.3 million in the third quarter of 2021, compared to $51.7 million in the prior quarter, primarily due to additional investment in R&D and marketing programs, along with increased hiring. Non-GAAP operating income was $85.9 million in the third quarter of 2021, compared to $77.2 million in the second quarter of 2021.

We exited the third quarter of 2021 with $1.4 billion in cash, cash equivalents and marketable securities and generated $113.4 million in cash flow from operations. Capital expenditures were $12.7 million in the third quarter of 2021, compared to $16.4 million in the second quarter of 2021.

Strong demand for our microinverter systems continued in the third quarter of 2021, while shipments of our Enphase Storage systems increased approximately 51%, compared to the second quarter of 2021. Our Load Control feature gained significant adoption during the third quarter. This feature provides homeowners the ability to conserve their energy consumption by shedding non-essential loads during an outage and thereby extending the backup duration. We also made several software and hardware updates to reduce commissioning times.

Product innovation remains at the cornerstone of our growth strategy. Yesterday, we announced our all-new, all-in-one Energy System with IQ8™ solar microinverters for customers in North America. Since the company’s inception, we invested in custom application specific integrated circuit (ASIC) chips for our microinverters, and today we see the payoff with a software-defined microinverter smart enough to form a microgrid. Many homeowners often assume that their solar systems will function if the sun is shining, even during a power outage. This has unfortunately not been true until today. Now, with IQ8 homeowners can realize the true promise of solar — to make and use their own power. IQ8 solar microinverters can provide Sunlight Backup during an outage, even without a battery.

In addition, we recently announced that our home energy systems will soon integrate with most leading models of home standby AC generators, providing enhanced performance and a glitch-free transition for homeowners during power outages. Homeowners can also monitor real-time power flow, start and stop their generator remotely, set quiet hours to prevent their generator from operating until their batteries fall below a designated threshold, and control it all with the Enphase app. The new feature functions without a generator automatic transfer switch and eliminates the power glitches that reset home electronic appliances when switching to generator power.

We continued to make excellent progress on digital transformation. Both of our recent acquisitions achieved record revenue in the third quarter of 2021. Enphase Montreal, which provides design and proposal software, added a significant number of new installers. We plan to release several new software features next year to improve the installer experience. Enphase Noida, which provides proposal and permitting services, also experienced a significant increase in customer demand and is focused on automating the creation of permit plan sets to further expand the installer base.

BUSINESS HIGHLIGHTS

On Aug. 26, 2021, Enphase Energy announced that it renewed its partnership with Grid Alternatives, a national nonprofit providing access to clean, affordable, renewable energy, transportation, and jobs to economic and environmental justice communities. Enphase will continue donating its industry-leading microinverter technology as part of the partnership to help GRID achieve its mission of accelerating a rapid, equitable transition to a world powered by renewable energy. 

On Sept. 21, 2021, Enphase Energy announced its participation in Hawaiian Electric’s Battery Bonus grid services program. The program offers a new incentive for homeowners on the island of Oahu who install a new home battery. Existing Hawaiian Electric net energy metering (NEM) customers enrolling in the Battery Bonus program are also eligible to add up to 5 kW of new solar capacity to their roofs without losing their existing NEM rate agreement, resulting in even more savings. 

On Sept. 27, 2021, Enphase Energy announced it had entered the Brazilian solar market with the introduction of its IQ7+™ microinverters. Enphase started shipping IQ7+ microinverters for residential and small commercial installers across Brazil starting in Oct. 2021. 

On Sept. 29, 2021 Enphase Energy announced that it further strengthened its presence in the European residential solar market with its expansion into Italy. Enphase is providing the IQ7™ family of microinverters, Q-Relay™ safety devices, and Enphase Envoy™ communications gateways, which connect Enphase systems to the Enphase Enlighten™ monitoring platform to residential installers across Italy.

On Oct. 18, 2021 Enphase Energy announced that it started shipping its Encharge™ battery storage system to customers in Belgium, further expanding the product’s availability in the European solar market. The Encharge battery storage system is also currently available to customers in Germany and North America. The Encharge battery storage system offers configurations ranging from 3.5kWh to 42kWh, along with the option to upgrade and expand through the lifetime of the system.

FOURTH QUARTER 2021 FINANCIAL OUTLOOK

For the fourth quarter of 2021, Enphase Energy estimates both GAAP and non-GAAP financial results as follows:

  • Revenue to be within a range of $390 million to $410 million, which includes shipments of 90 to 100 megawatt hours of Enphase Storage systems
  • GAAP gross margin to be within a range of 37.0% to 40.0%; non-GAAP gross margin to be within a range of 38.0% to 41.0%, excluding stock-based compensation expenses
  • GAAP operating expenses to be within a range of $119.0 million to $122.0 million, including $52.0 million estimated for stock-based compensation expenses and acquisition related costs and amortization
  • Non-GAAP operating expenses to be within a range of $67.0 million to $70.0 million, excluding $52.0 million estimated for stock-based compensation expenses and acquisition related costs and amortization. The non-GAAP estimates include increased investments in new products, software, and marketing, and a $3.6 million accrual for post combination expenses from prior acquisitions

(1) We sought refunds totaling approximately $39 million plus 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 is subject to review and approval by the U.S. Customs and Border Protection; therefore, we have assessed the probable loss recovery in the three and nine months ended September 30, 2020 is equal to the $23.0 million approved refund requests available to us prior to issuance of the financial statements on October 27, 2020. As of both the three and nine months ended September 30, 2020, we have recorded $23.0 million as a reduction to cost of revenues in our condensed consolidated statements of operations as the approved refunds relate to paid tariffs previously recorded to cost of revenues, therefore, we recorded the corresponding approved tariff refunds as credits to cost of revenues in the three and nine months ended September 30, 2020.

(2) Loss on partial settlement of convertible notes of less than $0.1 million for the three months ended June 30, 2021, primarily relates to the non-cash loss on partial settlement of $0.1 million aggregate principal amount of the Notes due 2025. Loss on partial settlement of convertible notes of $56.4 million for the nine months ended September 30, 2021 primarily relates to the $9.5 million non-cash loss on partial settlement of $87.1 million 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.

(3) Change in fair value of derivatives of $44.3 million for the nine months ended September 30, 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.
