1.    DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
Description of Business
Enphase Energy, Inc. (the “Company”) is a global energy technology company. The Company delivers smart, easy-to-use solutions that manage solar generation, storage and communication on one platform. The Company revolutionized the solar industry with its microinverter technology and produces a fully integrated solar-plus-storage solution.
Basis of Presentation and Consolidation
The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”). The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Unaudited Interim Financial Information
These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring items, considered necessary to present fairly the Company’s financial condition, results of operations, comprehensive income, stockholders’ equity and cash flows for the interim periods indicated. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the operating results for the full year.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Significant estimates and assumptions reflected in the financial statements include revenue recognition, allowance for doubtful accounts, stock-based compensation, deferred compensation arrangements, inventory valuation, accrued warranty obligations, fair value of investments, debt derivatives, convertible notes and contingent consideration, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, incremental borrowing rate for right-of-use assets and lease liability, legal contingencies and tax valuation allowance. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from those estimates due to risks and uncertainties, including uncertainty in the ongoing semiconductor supply and logistics constraints, and the continuing COVID-19 pandemic.
The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States. The Company filed audited consolidated financial statements, which included all information and notes necessary for such a complete presentation in conjunction with its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 filed with the SEC on February 11, 2022 (the “Form 10‑K”).
Summary of Significant Accounting Policies
There have been no changes to the Company’s significant accounting policies as described in Note 2, “Summary of Significant Accounting Policies” of the notes to consolidated financial statements included in Part II, Item 8 of the Form 10-K, other than as a result of the Company’s adoption of the new accounting guidance related to convertible senior notes, effective January 1, 2022, as discussed in “Recently Adopted Accounting Pronouncements” below.

Enphase Energy, Inc. | 2022 Form 10-Q | 8

ENPHASE ENERGY, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Recently Adopted Accounting Pronouncements
In August 2020, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update(“ASU”) 2020-06, “Debt - Debt with Conversion and Other Options (subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (subtopic 815-40)” (“ASU 2020-06”), which reduces the number of accounting models in ASC 470-20 that require separate accounting for embedded conversion features. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost as long as no other features require bifurcation and recognition as derivatives. By removing those separation models, the effective interest rate of convertible debt instruments will be closer to the coupon interest rate. Further, the diluted net income per share calculation for convertible instruments will require the Company to use the if-converted method. The treasury stock method should no longer be used to calculate diluted net income per share for convertible instruments.
The Company adopted ASU 2020-06 in the annual period beginning January 1, 2022, on a modified retrospective basis. Upon adoption of ASU 2020-06, the Company is no longer required to bifurcate the conversion feature related to the issuance of $575.0 million aggregate principal amount of its 0.0% convertible senior notes due 2028 (the “Notes due 2028”) and $632.5 million aggregate principal amount of its 0.0% convertible senior notes due 2026 (the “Notes due 2026”) in equity. Instead, the Company combined the previously separated equity component with the liability component, which together is now classified as debt, thereby eliminating the subsequent amortization of the debt discount. Similarly, the portion of issuance costs previously allocated to equity was reclassified to the carrying value of debt and amortized over the remaining terms of the convertible senior notes. Accordingly, the Company recorded a net decrease to additional paid-in capital by $207.9 million, net of tax to remove the equity component separately recorded for the conversion features associated with the convertible senior notes and equity component associated with the issuance costs, an increase to the carrying value of its convertible debt instrument by $244.5 million to reflect the full principal amount of the convertible senior notes outstanding net of issuance costs, a decrease to deferred tax liability of $62.3 million, and a decrease to accumulated deficit by $25.7 million, net of tax in the Company’s consolidated balance sheet with no impact on the Company’s consolidated statements of operations.
Also upon adoption of ASU 2020-06, the Company is no longer utilizing the treasury stock method for earnings per share impact for 0.25% convertible senior notes due 2025 (the “Notes due 2025”), Notes due 2026 and together with the Notes due 2028 (the “Convertible Senior Notes”). Instead, the Company is applying the if-converted method when reporting the number of potentially dilutive shares of common stock as the Company may at its election, settle its Convertible Senior Notes through payment or delivery, as the case may be, in cash, shares of its common stock or a combination of cash and shares of its common stock. Further, the Company under the relevant sections of the indentures, irrevocably may elect to settle principal in cash and any excess in cash or shares of the Company’s common stock for its Convertible Senior Notes. If and when the Company makes such election, there will be no adjustment to the net income and the Company will use the average share price for the period to determine the potential number of shares to be issued based upon assumed conversion to be included in the diluted share count.
Recently Issued Accounting Pronouncements
Not Yet Effective
In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" (“ASU 2021-08”). The standard requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, “Revenue from Contracts with Customers,” as if it had originated the contracts. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. The Company does not expect the adoption of ASU 2021-08 to have a significant impact on its condensed consolidated financial statements and plans to adopt the standard effective January 1, 2023.

4.    BUSINESS COMBINATIONS
Acquisition of SolarLeadFactory, LLC. (“SolarLeadFactory”)
On March 14, 2022, the Company completed the acquisition of 100% of the shares of SolarLeadFactory, a privately-held company. SolarLeadFactory provides high quality leads to solar installers. As part of the purchase price, the Company paid approximately $26.1 million in cash on March 14, 2022.
The acquisition has been accounted for as a business combination under the acquisition method, and accordingly, the total purchase price is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their respective fair values on the acquisition date.
In addition to the purchase price summarized above, the Company will be obligated to issue up to approximately $10.0 million in shares of common stock of the Company payable in the second quarter of 2023, subject to achievement of certain operational targets. As the additional payments require continuous employment of certain key employees of SolarLeadFactory and are subject to other conditions, these payments are being accounted for as post-combination expense and will be recognized ratably over the one-year period presuming conditions will be met.
The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the acquisition date, which are subject to change within the measurement period as the fair value assessments are finalized (in thousands):
Cash and cash equivalents$1,426 
Net tangible assets acquired813 
Intangible assets11,200 
Goodwill12,612 
Net assets acquired$26,051 
The excess of the consideration paid over the fair values assigned to the assets acquired and liabilities assumed represents the goodwill resulting from the acquisition. Goodwill is primarily attributable to expected synergies in the Company’s solar offerings and cross-selling opportunities. The entire goodwill amount is expected to be deductible for U.S. federal income tax purposes over 15 years.

8.    FAIR VALUE MEASUREMENTS
The accounting guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.
The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset’s or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:
Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of such assets or liabilities do not entail a significant degree of judgment.
Level 2 - Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.
Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
The following table presents assets and liabilities measured at fair value on a recurring basis using the above input categories:
