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 connect solar generation, storage and management on one intelligent platform. The Company revolutionized solar 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 (“U.S”), or 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. 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 U.S. The Company filed audited consolidated financial statements, which included all information and notes necessary for such a complete presentation in conjunction with its 2018 Annual Report on Form 10-K.
Unaudited Interim Financial Information
These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “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 (loss) and cash flows for the interim periods indicated. The results of operations for the three months ended March 31, 2019 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, inventory valuation and accrued warranty obligations. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from management’s estimates using different assumptions or under different conditions.

Recently Adopted Accounting Pronouncements
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842).” ASU 2016-02 requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. The guidance requires lessees to recognize all leases, with certain exceptions, on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee must recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. On January 1, 2019, the Company adopted ASU 2016-02 using the modified retrospective transition option of applying the new standard at the adoption date for all leases with terms greater than 12 months. The Company elected certain practical expedients upon adoption and as such did not reassess the following: 1) whether any expired or existing contracts are or contain leases; 2) lease classification for any expired or existing leases; 3) initial direct costs for any expired or existing leases; 4) whether existing or expired land easements are or contain leases; and 5) regarding the lease term, from a hindsight perspective, whether or not the Company is reasonably certain to exercise the lease options. However, the Company will evaluate new or modified land easements under the new guidance after the commencement date. The Company also elected the practical expedient to not separate lease and non-lease components. The adoption of ASU 2016-02 on January 1, 2019 resulted in an increase in operating leases, right of use asset of $8.4 million, an increase in other liabilities of $6.8 million, an increase in accrued liabilities and other of $1.5 million and a decrease in other assets of $0.1 million on the Company’s consolidated balance sheets with no impact on the Company’s consolidated statements of operations.
In June 2018, the FASB issued ASU 2018-07, “Compensation - Stock Compensation: Improvements to Non-employee Share-Based Payment Accounting.” ASU 2018-07 was issued to provide to provide guidance on share-based payments granted to non-employees in exchange for goods or services used or consumed in an entity’s own operations and supersedes the guidance in ASC 505-50, “Equity-Based Payments to Non-Employees.” ASU 2018-07 aligns much of the guidance on measuring and classifying non-employee awards with that of awards to employees. The Company adopted ASU 2018-07 on January 1, 2019 a modified retrospective basis. The adopted standard did not have a material impact on the consolidated financial statements.
Recently Issued Accounting Pronouncements Not Yet Effective
In August 2018, the FASB issued ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” to reduce diversity in practice in accounting for the costs of implementing cloud computing arrangements that are service contracts. ASU 2018-15 allows entities to apply the guidance in the ASC 350-40, “Intangibles–Goodwill and Other–Internal-Use Software,” to determine which implementation costs are eligible to be capitalized as assets in a cloud computing arrangement that is considered a service contract. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. Entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively and are required to make certain disclosures in the interim and annual period of adoption. The Company is currently evaluating the impact this update will have on its consolidated financial statements.

In August 2018, the Company acquired certain finite-lived intangible assets in its acquisition of SunPower Corporation’s (“SunPower”) microinverter business pursuant to an Asset Purchase Agreement (“APA”), primarily developed technology and customer relationships. See Note 20. “Acquisition,” of the notes to consolidated financial statements included in Item 8 of the Company’s 2018 Form 10‑K filed with the SEC on March 15, 2019 for additional information related to this acquisition.

Amortization of developed technology, patents and licensed technology is primarily recorded to sales and marketing expense. The developed technology acquired from the Company’s acquisition of SunPower’s microinverter business is embedded in the microinverters that SunPower sells to its customers. The Company does not actively use the developed technology acquired from SunPower and holds the developed technology to prevent others from using it. Accordingly, the Company accounts for the developed technology as a defensive intangible asset and amortizes the associated value over a period of six years from the date of acquisition.
The master service agreement (“MSA”) negotiated with SunPower in August 2018 provides the Company with the exclusive right to supply SunPower with module level power electronics for a period of five years, with options for renewals. The exclusivity arrangement extends throughout the term of the MSA, which comprises all of the expected cash flows from the customer relationship intangible asset, and was a condition to, and was an essential part of the acquisition of the SunPower’s microinverter business by the Company. As the fair value ascribed to the customer relationship intangible asset represents payments to a customer, the Company amortizes the value of the customer relationship intangible asset as a reduction to revenue using a pattern of economic benefit method over a useful life of nine years.

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 the Company’s liabilities that were measured at fair value on a recurring basis and its categorization within the fair value hierarchy:

Fair Value Option for Warranty Obligations Related to Microinverters Sold Since January 1, 2014
The Company estimates the fair value of warranty obligations by calculating the warranty obligations in the same manner as for sales prior to January 1, 2014 and applying an expected present value technique to that result. The expected present value technique, an income approach, converts future amounts into a single current discounted amount. In addition to the key estimates of failure rates, claim rates and replacement costs, the Company used certain Level 3 inputs which are unobservable and significant to the overall fair value measurement. Such additional assumptions included a discount rate based on the Company’s credit-adjusted risk-free rate and compensation comprised of a profit element and risk premium required of a market participant to assume the obligation.
The following table provides information regarding changes in nonfinancial liabilities related to the Company’s warranty obligations measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the periods indicated:

Quantitative and Qualitative Information about Level 3 Fair Value Measurements

Sensitivity of Level 3 Inputs - Warranty Obligations
Each of the significant unobservable inputs is independent of the other. The profit element and risk premium are estimated based on requirements of a third-party participant willing to assume the Company’s warranty obligations. The credit‑adjusted risk‑free rate (“discount rate”) is determined by reference to the Company’s own credit standing at the fair value measurement date. Increasing the profit element and risk premium input by 100 basis points would result in a $0.1 million increase to the liability. Decreasing the profit element and risk premium by 100 basis points would result in a $0.1 million reduction of the liability. Increasing the discount rate by 100 basis points would result in a $0.5 million reduction of the liability. Decreasing the discount rate by 100 basis points would result in a $0.5 million increase to the liability.

Valuation of Equity Awards
Stock Options
The fair value of each option granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions:
Expected term—The expected term of the option awards represents the period of time between the grant date of the option awards and the date the option awards are either exercised, converted or canceled, including an estimate for those option awards still outstanding. The Company used the simplified method, as permitted by the SEC for companies with a limited history of stock option exercise activity, to determine the expected term for its option grants.
Expected volatility—The expected volatility was calculated based on the Company’s historical stock prices, supplemented as necessary with historical volatility of the common stock of several peer companies with characteristics similar to those of the Company.
Risk-free interest rate—The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant and with a maturity that approximated the Company’s expected term.
Dividend yield—The dividend yield was based on the Company’s dividend history and the anticipated dividend payout over its expected term.
The following table presents the weighted-average grant date fair value of options granted for the periods presented and the assumptions used to estimate those values using a Black-Scholes option pricing model:

Restricted Stock Units
The fair value of the Company’s restricted stock units (“RSU”) awards granted is based upon the closing price of the Company’s stock price on the date of grant.
Performance Stock Units
The fair value of the Company’s non-market performance stock units (“PSU”) awards granted was based upon the closing price of the Company’s stock price on the date of grant. The fair value of awards of the Company’s PSU awards containing market conditions was determined using a Monte Carlo simulation model based upon the terms of the conditions, the expected volatility of the underlying security, and other relevant factors.

INCOME TAXES
The Company used the discrete tax approach in calculating the tax expense for the three months ended March 31, 2019 and 2018 due to the fact that a relatively small change in the Company’s projected pre-tax net income (loss) could result in a volatile effective tax rate. Under the discrete method, the Company determines its tax (expense) benefit based upon actual results as if the interim period was an annual period. The tax provision recorded was primarily related to income taxes attributable to its foreign operations.

NET INCOME (LOSS) PER SHARE
Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed in a similar manner, but it also includes the effect of potential common shares outstanding during the period, when dilutive. Potential common shares include stock options, RSUs, PSUs, shares to be purchased under the Company’s employee stock purchase program (“ESPP”), and the convertible notes. The dilutive effect of potentially dilutive common shares is reflected in diluted earnings per share by application of the treasury stock method. To the extent these potential common shares are antidilutive, they are excluded from the calculation of diluted net income (loss) per share.
The following table presents the computation of basic and diluted net income (loss) per share for the periods presented:

As the Company incurred a net loss for the three months ended March 31, 2018, potential dilutive securities from employee stock options, RSUs, PSUs, and shares to be purchased under the Company’s ESPP have been excluded from the diluted net loss per share computation because the effect of including such shares would have been antidilutive.
The following outstanding shares of common stock equivalents were excluded from the calculation of the diluted net income (loss) per share attributable to common stockholders because their effect would have been antidilutive:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Forward-Looking Statements
The following discussion and analysis of our financial condition and results of operations should be read together with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements reflecting our current expectations and involves risks and uncertainties. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “intend,” “potential” or “continue” or the negative of these terms or other comparable terminology. Such statements, include but are not limited to statements regarding our expectations as to future financial performance, expense levels, liquidity sources, the capabilities and performance of our technology and products and planned changes, timing of new product releases, our business strategies, including anticipated trends, growth and developments in markets in which we target, the anticipated market adoption of our current and future products, performance in operations, including component supply management, product quality and customer service, and the anticipated benefits and risks relating to the transaction with SunPower Corporation. Our actual results and the timing of events may differ materially from those discussed in our forward-looking statements as a result of various factors, including those discussed below and those discussed in the section entitled “Risk Factors” included in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2018.
Overview and Q1 2019 Highlights
We are a global energy technology company. We deliver smart, easy-to-use solutions that connect solar generation, storage and management on one intelligent platform. We revolutionized solar with our microinverter technology and produces a fully-integrated solar plus storage solution. We have shipped more than 20 million microinvertersand more than 895,000 Enphase residential and commercial systems have been deployed in over 125 countries.
We sell our solutions primarily to distributors who resell them to solar installers. We also sell directly to large installers, OEMs, strategic partners and homeowners.
On January 28, 2019, we repaid in full the remaining principal amount of the Term Loans of approximately $39.5 million plus accrued interest and fees owed to lenders affiliated with Tennenbaum Capital Partners, LLC.
Products
Enphase IQ Microinverter System
The Enphase IQ™ microinverter is a key component of the Enphase Home Energy Solution™, which can also include our Envoy™ Communications Gateway with IQ Combiner+, Enphase Enlighten™, a cloud-based energy management platform, and our Enphase AC Battery™. System owners can use Enphase Enlighten to monitor their home’s solar generation, energy storage and consumption from any web-enabled device.
Our IQ 7X™ product addresses 96-cell photovoltaic (“PV”) modules up to 400W direct current (“DC”) and with its 97.5 percent California Energy Commission (“CEC”) efficiency rating, is ideal for integration into high power modules. In the first quarter of 2019, we shipped limited quantities of our new product IQ 7A™ which addresses up to 450W DC modules. In addition, we recently started shipping our IQ 7AS™ microinverters to SunPower Corporation (“SunPower”), which is expected to integrate our IQ 7AS into its 66-cell Next Generation Technology (“NGT”) DC modules.
Our IQ 8™ system is based upon our grid-agnostic “always on” technology called Ensemble. This system has four components: 1) energy generation, which is accomplished with the grid-agnostic microinverter IQ8; 2) energy storage, which is achieved by the Encharge™ battery with capacities of 3.3 kWh, 10 kWh and 13.2 kWh; 3) communication and control, which consists of the automatic transfer switch called Enpower™, and the combiner box with the Envoy gateway; and 4) Enlighten, which is the internet of things, or IoT, cloud software. We anticipate introducing Ensemble in a phased manner starting in the fourth quarter of 2019.

Three months ended March 31, 2019 and 2018
Cost of revenues increased by 29% for the three months ended March 31, 2019, as compared to the same period in 2018, primarily due to higher volume of microinverter units sold and expedited freight costs, partially offset by a decrease in the cost of our products as a result of our cost reduction efforts. Gross margin increased by 7.1 percentage points for the three months ended March 31, 2019, as compared to the same period in 2018. The increase in gross margin was primarily attributable to higher product margins as a result our IQ 7 family of microinverters, which has a lower cost than previous microinverters, as well as our overall pricing management efforts. In the first quarter of 2019, IQ 7 sales represent 94% of our total microinverter sales, as compared to 8% of our total microinverter sales in the first quarter of 2018.

Research and development expense increased by 12% for the three months ended March 31, 2019, as compared to the same period in 2018. The increase is due to higher expenses associated with the development of our products, personnel-related costs, equipment costs, and facility costs. The increase in personnel-related expenses included higher bonus and stock-based compensation expense, partially offset by lower compensation and benefit costs associated with moving certain functions to lower cost locations as part of restructuring actions taken in 2018.

The increase is primarily due to an increase in personnel-related expenses and additional consulting and advisory fees due to our first year of being subject to SOX auditor attestation requirements, partially offset by lower facilities costs and $1.8 million paid to resolve a dispute with a supplier in 2018 that did not repeat in 2019. The increase in personnel-related expenses included higher stock-based compensation expense, employee compensation expense and benefit costs.

Other expense, net for the three months ended March 31, 2018 includes $2.3 million of interest expense related to our term loans and $0.4 million loss related to foreign currency exchange and remeasurement.
Liquidity and Capital Resources
Sources of Liquidity
As of March 31, 2019, we had $78.1 million in cash and cash equivalents and working capital of $66.7 million. Cash and cash equivalents held in the U.S. were $67.1 million and consisted primarily of U.S. Government money market mutual funds and non-interest-bearing checking deposits, with the remainder held in various foreign subsidiaries. We consider amounts held outside the U.S. to be accessible and have provided for the estimated U.S. income tax liability associated with our foreign earnings.
Term Loans. On January 28, 2019, we repaid in full the remaining principal amount of the Term Loans of approximately $39.5 million plus accrued interest and fees owed to lenders affiliated with Tennenbaum Capital Partners, LLC.
Convertible Notes. In August 2018, we sold $65.0 million aggregate principal amount of convertible senior notes due 2023 (the “Notes”) in a private placement. The Notes are senior, unsecured and bear interest at a rate of 4.0% per year, payable semi-annually on February 1 and August 1 of each year, beginning on February 1, 2019. The Notes will mature on August 1, 2023, unless earlier repurchased by the Company or converted at the option of the holders.
We believe that our existing cash and cash equivalents and cash flows from our operating activities will be sufficient to meet our anticipated cash needs for at least the next 12 months.
Cash Flows. The following table summarizes our cash flows for the periods presented:

Cash Flows from Operating Activities
For the three months ended March 31, 2019, net cash provided by operating activities of $17.1 million was primarily attributable to net income of $2.8 million, non-cash charges of $8.4 million, cash from operating assets and liabilities of $3.8 million, and a one-time charge of $2.2 million related to settlement of our term loan. The primary driver of cash inflows from changes in operating assets and liabilities was a $4.9 million increase in accounts payable due to both successful re-negotiations of our vendor payment terms as well as the timing of vendor payments, a $3.3 million decrease in inventory due to higher demand and continued improvement in the management of our supply chain, and a $1.6 million increase in deferred revenues, which were partially offset by $3.3 million increase in accounts receivable due to higher sales.

 
Enphase Energy, Inc. | Q1 2019 Form 10-Q | 25

Table of Contents

For the three months ended March 31, 2018, net cash provided by operating activities of $3.4 million was primarily attributable to a net loss of $5.1 million offset by non-cash charges of $5.0 million and net cash inflows from changes in operating assets and liabilities of $3.5 million. Non-cash charges included $1.6 million of stock-based compensation, $2.3 million of depreciation and amortization, and $0.6 million provision for doubtful accounts. The primary driver of cash outflows from changes in operating assets and liabilities was a $9.1 million decrease in accounts receivable due to seasonally lower revenues and a $7.5 million decrease in inventory due to supply chain management efforts, which were partially offset by an $12.0 million decrease in accounts payable as a result of lower inventory levels and the timing of vendor payments.
Cash Flows from Investing Activities
For the three months ended March 31, 2019, net cash used in investing activities of $0.7 million primarily resulted from purchases of test and assembly equipment and capitalized costs related to internal-use software.
For the three months ended March 31, 2018, net cash used in investing activities of $1.0 million primarily resulted from purchases of test and assembly equipment and capitalized costs related to internal-use software.
Cash Flows from Financing Activities
For the three months ended March 31, 2019, net cash used in financing activities of $44.4 million consisted of $44.7 million of principal payments on debts and financing fees associated with repayment of our term loan, which was partially offset by $0.3 million in net proceeds from sales of common stock under our employee stock incentive program.
For the three months ended March 31, 2018, net cash provided by financing activities of $21.7 million consisted of $20.2 million in net proceeds from sales of common stock and $2.3 million in net proceeds from the sale of certain long-term financing receivables. These proceeds were partially offset by a $0.8 million principal payment on our term debt.
Contractual Obligations
Other than as described below, there were no material changes during the three months ended March 31, 2019 to our contractual commitments as presented in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2018 Form 10‑K filed with the SEC on March 15, 2019. See Note 9. “Commitments and Contingent Liabilities,” of the condensed consolidated financial statements.
On January 28, 2019, we repaid in full the remaining principal amount of the Term Loans of approximately $39.5 million plus accrued interest and fees owed to lenders affiliated with Tennenbaum Capital Partners, LLC.
Off-Balance Sheet Arrangements
As of March 31, 2019, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.
Critical Accounting Policies
Our condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S., or GAAP. In connection with the preparation of our condensed consolidated financial statements, we are required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our consolidated financial statements are prepared. On a regular basis, we review the accounting policies, assumptions, estimates and judgments to ensure that our condensed consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

 
Enphase Energy, Inc. | Q1 2019 Form 10-Q | 26

Table of Contents

We consider an accounting policy to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the condensed consolidated financial statements.
Adoption of New and Recently Issued Accounting Pronouncements
Refer to Note 1. “Summary of Significant Accounting Policiesof the notes to condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for a discussion of adoption of new and recently issued accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
For quantitative and qualitative disclosures about market risk, see Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” of our 2018 Form 10‑K filed with the SEC on March 15, 2019. Our exposures to market risk have not changed materially since December 31, 2018.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2019. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, includes, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of March 31, 2019, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Changes in Internal Control
There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
