Total revenue for the fourth quarter of 2022 increased 14%, compared to the third quarter of 2022, driven by strong demand for Enphase Energy Systems™. Our revenue in the United States for the fourth quarter of 2022 increased approximately 15% and our revenue in Europe increased approximately 21%, compared to the third quarter of 2022. Our non-GAAP gross margin was 43.8% in the fourth quarter of 2022, compared to 42.9% in the third quarter of 2022, driven by IQ8™ Microinverter product mix.

Our non-GAAP operating expenses were $87.7 million in the fourth quarter of 2022, compared to $78.6 million in the third quarter of 2022, primarily due to investment in international growth, customer service, and R&D. Our non-GAAP operating income was $229.4 million in the fourth quarter of 2022, compared to $194.0 million in the third quarter of 2022.

We exited the fourth quarter of 2022 with $1.61 billion in cash, cash equivalents, and marketable securities and generated $253.7 million in cash flow from operations in the fourth quarter of 2022. Our capital expenditures were $16.4 million in the fourth quarter of 2022, compared to $8.9 million in the third quarter of 2022. The increase was primarily due to investment in additional contract manufacturing sites and R&D equipment.

IQ8 Microinverters constituted approximately 55% of all our microinverter shipments during the fourth quarter of 2022. We introduced IQ8 Microinverters in France and the Netherlands in the fourth quarter of 2022, marking the first expansion into international markets for the product since its successful launch in North America in late 2021.

Our IQ Battery shipments were 122.1 megawatt hours in the fourth quarter of 2022, compared to 133.6 megawatt hours in the third quarter of 2022. We made significant software upgrades to continue improving the installer and homeowner experience and brought commissioning times down. We shipped IQ Batteries to North America, Germany, and Belgium during the fourth quarter of 2022. We now have approximately 2,300 installers worldwide that are certified to install our IQ Batteries.

We are adding additional manufacturing capacity in the United States due to the strong global demand for our products as well as the incentives related to the Inflation Reduction Act (IRA). We plan to begin domestic manufacturing in the second quarter of 2023 with a new contract manufacturing partner and in the second half of 2023 with our two existing contract manufacturing partners.

We began manufacturing Enphase-branded electric vehicle (EV) chargers at our contract manufacturing facility in Mexico, helping us to increase capacity and reduce costs. We expect to introduce IQ smart EV chargers to customers in the United States in the first half of 2023. They will provide connectivity and control, enabling use cases like green charging and allowing homeowners visibility into the operation of their Enphase solar-plus-storage-plus-EV system through the Enphase^® App.

We continued to make progress on our installer platform. We made updates to Solargraf℠ software during the fourth quarter of 2022, incorporating battery design and proposal, document management, consumption modeling, and several other improvements requested by our installer partners. In addition, we made significant strides in automating the creation of permit plan sets with Solargraf software. We now have more than 1,000 installers using the software.

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 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.

Loss on partial settlement of convertible notes. This item is reflected in other income (expense), net and represents (i) the difference between the carrying value and the fair value of the settled convertible notes and (ii) the inducement loss for the difference between the value of the shares issued to settle the convertible notes and the value of the shares that would have been issued under the original conversion terms with respect to the repurchased Notes due 2025, which is non-cash in nature and 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 plus deemed repayment of convertible notes attributable to accreted debt discount reported in operating activities less purchases of property and equipment.

(2)		Calculation of non-GAAP diluted net income per share for the three months ended December 31, 2022, September 30, 2022 and December 31, 2021, excludes convertible Notes due 2023 interest expense, net of tax of less than $0.1 million in each period from non-GAAP net income. Calculation of non-GAAP diluted net income per share for the twelve months ended December 31, 2022 and 2021 excludes convertible Notes due 2023 interest expense, net of tax of approximately $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 the in-the-money portion of convertible Notes due 2024 totaling 38 thousand shares and 768 thousand shares in the three months and twelve months ended December 31, 2021 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 2024. We excluded the in-the-money portion of convertible Notes due 2025 totaling 1,253 thousand shares and 763 thousand shares in the three months ended December 31, 2022 and 2021, respectively, and 929 thousand shares in the twelve months ended December 31, 2021 from non-GAAP weighted-average diluted shares. We excluded in-the-money portion of convertible Notes due 2026 and Notes due 2028 totaling 2,057 thousand shares and 2,018 thousand shares, respectively, each in the three months and twelve months ended December 31, 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 2026 and Notes due 2028.
