Total revenue for the second quarter of 2023 was $711.1 million, compared to $726.0 million in the first quarter of 2023. Our revenue in the United States for the second quarter of 2023 decreased over 12% due to macroeconomic conditions, while our revenue in Europe increased approximately 25%, compared to the first quarter of 2023.

Our non-GAAP gross margin was 46.2% in the second quarter of 2023, compared to 45.7% in the first quarter of 2023, driven by increased IQ8™ product mix and improved logistics. Our non-GAAP operating expenses were $98.2 million in the second quarter of 2023, compared to $98.4 million in the first quarter of 2023. Our non-GAAP operating income was $230.5 million in the second quarter of 2023, compared to $233.6 million in the first quarter of 2023.

We exited the second quarter of 2023 with $1.8 billion in cash, cash equivalents, and marketable securities and generated $269.2 million in cash flow from operations in the second quarter of 2023. Our capital expenditures were $44.0 million in the second quarter of 2023, compared to $22.5 million in the first quarter of 2023. The increase was primarily due to investment in U.S. manufacturing and R&D equipment.

IQ8 Microinverters constituted approximately 78% of all our microinverter shipments during the second quarter of 2023. In addition to the U.S., we are now shipping IQ8 Microinverters into France, the Netherlands, Spain, Portugal, Poland, and Germany to support newer high-powered solar panels.

Our IQ Battery shipments were 82.3 megawatt hours in the second quarter of 2023, compared to 102.4 megawatt hours in the first quarter of 2023. We recently introduced IQ Batteries into Spain and Portugal and launched the IQ™ Battery 5P, our most powerful battery-to-date, in Australia, the United States, and Puerto Rico during the second quarter of 2023. The IQ Battery 5P is modular and can deliver 3.84 kW continuous power and 7.68 kW peak power, enabling homeowners to start heavy loads like air conditioners easily during power outages. More than 3,500 installers worldwide are certified to install our IQ Batteries.

We began shipments of our microinverters in the second quarter of 2023 from our contract manufacturer Flex in Columbia, South Carolina. We are pleased that President Biden was able to visit the Flex facility and inaugurate the function. In addition, we began shipments from our new contract manufacturing partner Foxconn in Mount Pleasant, Wisconsin. We shipped approximately 50,000 units from these two U.S. contract manufacturers in the second quarter of 2023 and realized a net IRA benefit of $1.6 million. The Inflation Reduction Act (IRA) has enabled us to begin manufacturing in the United States, creating new jobs, advancing the country's clean energy economy, and contributing to the growth of our business. We remain on track to begin shipments from a third U.S. contract manufacturer in the third quarter of 2023.

As part of our share repurchase program authorized by our Board of Directors in May 2021, we repurchased approximately 1.25 million shares in the second quarter of 2023 at an average price of $159.43 for a total of approximately $200 million. This completed our $500 million share repurchase program authorized in May 2021.

Our Board of Directors has recently authorized a new share repurchase program pursuant to which we may repurchase up to an aggregate of $1.0 billion of our common stock. Subject to applicable rules and regulations, the stock repurchases may be made from time to time, through solicited or unsolicited transactions in the open market, in privately negotiated transactions or pursuant to a Rule 10b5-1 plan. The timing, price and volume of repurchases will be based on market conditions, relevant securities laws, and other considerations. The share repurchase program may be discontinued or amended at any time by our Board of Directors and expires on July 26, 2026.

Use of non-GAAP Financial Measures

Enphase Energy 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 (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 Enphase Energy include non-GAAP gross profit, gross margin, operating expenses, income from operations, net income, net income per share (basic and diluted), and free cash flow.

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 Enphase Energy’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. Enphase Energy 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. Enphase Energy 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 below, 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 Enphase Energy’s current operating performance and a comparison to its past operating performance:

Stock-based compensation expense. Enphase Energy 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 Enphase Energy’s stock price at the time of an award over which management has limited to no control.

Acquisition related expenses and amortization. This item represents expenses incurred related to Enphase Energy’s business acquisitions, 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 Enphase Energy’s ongoing financial performance.

Restructuring and asset impairment charges. Enphase Energy excludes restructuring and asset impairment related 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 cash-based severance costs and asset write-downs of property and equipment, and other contract termination costs resulting from restructuring initiatives.

Non-cash interest expense. This item consists primarily of amortization of debt issuance costs and accretion of debt discount because these expenses do not represent a cash outflow for Enphase Energy except in the period the financing was secured and such amortization expense is not reflective of Enphase Energy’s ongoing financial performance.

Non-GAAP income tax adjustment. This item represents the amount adjusted to Enphase Energy’s GAAP tax provision or benefit to report the non-GAAP tax amount based on cash tax expense and reserves for periods prior to 2023. Effective January 1, 2023, Enphase Energy updated its methodology of computing the non-GAAP income tax adjustment from reporting cash tax expense and reserves to the projected non-GAAP annualized effective tax rate as Enphase Energy utilized most of its net operating loss and tax credit carryforwards in the year ended December 31, 2022 and became a significant cash taxpayer in the United States. Going forward, Enphase Energy will exclude the income tax effects of GAAP adjustments such as stock-based compensation, amortization of purchased intangibles, and other non-recurring items that are not reflective of Enphase Energy ongoing financial performance.

Free cash flow. This item represents net cash flows from operating activities less purchases of property and equipment.

(2) Calculation of non-GAAP diluted net income per share for the three months ended June 30, 2023, March 31, 2023 and June 30, 2022, as well as the six months ended June 30, 2023 and 2022, excludes convertible Notes due 2023 interest expense, net of tax of less than $0.1 million in each period from non-GAAP net income.

(3) Effect of dilutive in-the-money portion of convertible senior notes and warrants are included in the GAAP weighted-average diluted shares in periods where we have GAAP net income. We excluded convertible Notes due 2025, Notes due 2026 and Notes due 2028 totaling 5,328 thousand shares in each of the three months ended June 30, 2023 and, March 31, 2023, and the six months ended June 30, 2023, from non-GAAP weighted-average diluted shares as we entered into convertible note hedge transactions that reduce potential dilution to our common stock upon any conversion of the Notes due 2025, Notes due 2026 and Notes due 2028. We excluded convertible Notes due 2026 and Notes due 2028 totaling 4,075 thousand shares in each of the three and six months ended June 30, 2022 from non-GAAP weighted-average diluted shares as we entered into convertible note hedge transactions that reduce potential dilution to our common stock upon any conversion of the Notes due 2025, Notes due 2026 and Notes due 2028.
