Diluted EPS $ (0.38) $ 0.50 $ 0.08 $ 0.17 $ 0.38 $ 0.18

Our non-GAAP gross margin increased to 39.6% from 39.5% in the first quarter of 2020, driven by disciplined pricing and cost management. Non-GAAP operating expenses decreased to $26.0 million in the second quarter of 2020, compared to $28.5 million in the prior quarter, primarily due to our tight spending controls. Non-GAAP operating income was $23.7 million, compared to $52.8 million in the prior quarter.

We exited the second quarter with $607.3 million in cash and generated $25.4 million in cash flow from operations. Inventory was $31.2 million at the end of the second quarter of 2020, compared to $34.6 million at the end of the first quarter of 2020. I am proud of our team’s excellent inventory management and control.

We shipped our Encharge energy storage systems in June for pilot runs to a few of our installers and the feedback has been good. Encharge storage systems feature Ensemble™ energy management technology, which powers the world’s first grid-agnostic microinverter-based storage system. We started Encharge production shipments in July to customers in North America. We are pleased with the initial feedback from our customers, who

see the Encharge energy storage system as a safe, reliable and powerful option for energy independence. I want to thank our engineers worldwide who worked tirelessly to bring this breakthrough product to market.

We continue to focus relentlessly on customer experience. The employees in all four of our customer experience centers – the U.S., Europe, India, and Australia, are fully supporting installers and homeowners, while working from home. Our worldwide Net Promoter Score was 66% in the second quarter of 2020, a slight increase from 64% in the prior quarter. During the second quarter of 2020, we launched the online Enphase Community which gives installers and homeowners the ability to communicate directly about Enphase products. In addition, we opened online stores in Europe and Australia to better service installers and homeowners. These stores, along with our U.S. online store, are increasing the accessibility of our clean energy solutions.

We continue to navigate through the COVID-19 pandemic with strong support from our partners and customers. Our sales and operations teams were laser-focused on managing the channel during the second quarter of 2020, working closely with our installers and distributors. While we saw a rebound in customer demand in June and July, we are carefully monitoring the resurgence of the COVID-19 pandemic in several states. We have a resilient business model that enables strong cash flow generation even during difficult economic periods, enabling us to invest in product innovation and digital transformation. We are well-positioned with Ensemble and look forward to accelerating the introduction of new products over the next eighteen months.

Use of Non-GAAP Financial Measures

The Company has presented certain non-GAAP financial measures in this press release. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States of America, or GAAP. Reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure can be found in the accompanying tables to this press release. Non-GAAP financial measures presented by the Company include non-GAAP gross profit, gross margin, operating expenses, income from operations, net income and net income per share.

These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. The Company believes that these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.

As presented in the “Reconciliation of Non-GAAP Financial Measures” tables in the accompanying press release, each of the non-GAAP financial measures excludes one or more of the following items for purposes of calculating non-GAAP financial measures to facilitate an evaluation of the Company’s current operating performance and a comparison to its past operating performance:

Stock-based compensation expense. The Company excludes stock-based compensation expense from its non-GAAP measures primarily because they are non-cash in nature. Moreover, the impact of this expense is significantly affected by the Company’s stock price at the time of an award over which management has limited to no control.

Restructuring and asset impairment charges. The Company excludes restructuring charges due to the nature of the expenses being unplanned and arising outside the ordinary course of continuing operations. These costs primarily consist of fees paid for restructuring-related management consulting services, cash-based severance costs and modification of stock-based compensation related to workforce reduction actions, asset write-downs of property and equipment and lease loss reserves, and other contract termination costs resulting from restructuring initiatives.

Acquisition related expenses and amortization. This item represents expenses incurred related to the Company’s acquisition of SunPower’s microinverter business, which are non-recurring in nature, and amortization of acquired intangible assets, which is a non-cash expense. Acquisition related expenses and amortization of acquired intangible assets are not reflective of the Company's ongoing financial performance.

Non-recurring debt prepayment fees and non-cash interest. This item consists primarily of amortization of debt issuance costs, accretion of debt discount and non-recurring debt settlement costs, because these expenses does not represent a cash outflow for the Company except in the period the financing was secured or when the financing was settled, and such amortization expense or settlement of debt costs is not reflective of the Company’s ongoing financial performance.

Change in fair value of derivatives. This item is reflected in other income (expense), net and represents changes in fair value of the conversion option in the convertible notes due 2025, as well as the convertible note hedge and warrant transactions, which is non-cash in nature and is not reflective of the Company’s ongoing financial performance.

Non-GAAP income tax adjustment. This item represents the amount adjusted to the Company’s GAAP tax provision or benefit to present the non-GAAP tax amount based on cash tax expense and reserves.

(1) Change in fair value of derivatives of $59.7 million and $44.3 million for the three and six months ended June 30, 2020, respectively, 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.
