    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

    (Unaudited)

     

     

    1. BASIS OF PRESENTATION

     

    The accompanying unaudited condensed consolidated financial statements have been prepared by Monolithic Power Systems, Inc. (the “Company” or “MPS”) in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted in accordance with these accounting principles, rules and regulations. The information in this report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 29, 2024.

     

    In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. The financial statements contained in this Quarterly Report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2024 or for any other future periods.

     

    Summary of Significant Accounting Policies 
     
    There have been no changes to the Company’s significant accounting policies during the three and nine months ended September 30, 2024. In addition to those described in the Company’s audited consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2023, the Company is subject to the following significant accounting policy due to its recent acquisition.
     

    Goodwill and Acquisition-Related Intangible Assets 
     
    Goodwill represents the excess of fair value of purchase consideration over fair value of net tangible and identifiable intangible assets acquired as of the date of an acquisition. In-process research and development (“IPR&D”) assets represent the fair value of incomplete research and development (“R&D”) projects that had not reached technological feasibility as of the date of acquisition. IPR&D assets are initially capitalized at fair value as intangible assets with indefinite lives. When IPR&D projects are completed, they are reclassified as amortizable intangible assets and are amortized over their estimated useful lives. Alternatively, if IPR&D projects are abandoned, they are impaired and expensed as R&D costs. Acquisition-related intangible assets with finite lives consist of developed technologies, which are amortized on a straight-line basis over their estimated remaining useful lives. The amortization expense is recorded in cost of revenue in the Condensed Consolidated Statements of Operations.

     

    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 and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions used in these condensed consolidated financial statements primarily include those related to revenue recognition, inventory valuation, valuation of share-based awards, contingencies and income tax valuation allowances. Actual results could differ from these estimates and assumptions, and any such differences may be material to the Company’s condensed consolidated financial statements.

     

    New Accounting Pronouncements Not Yet Adopted as of September 30, 2024

     

    In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which aims to improve disclosures regarding a public entity’s reportable segments, primarily through more comprehensive disclosures around significant segment expenses. The standard is effective for annual periods beginning January 1, 2024 and for interim periods beginning January 1, 2025, and should be applied retroactively to all prior periods presented. The Company is evaluating the potential effect that the updated standard will have on its financial statement disclosures.

     

    In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which aims to improve an entity’s income tax disclosures around its effective rate reconciliation, income taxes paid, disaggregation of income before income taxes and income tax expense. The guidance will be effective for annual periods beginning January 1, 2025. The standard should be applied prospectively but retrospective application is permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

    2. REVENUE RECOGNITION

     

    Revenue from Product Sales

     

    The Company generates revenue primarily from product sales, which include assembled and tested integrated circuits (“ICs”), power modules as well as dies in wafer form. These product sales accounted for 99% of the Company’s total revenue for each of the three and nine months ended September 30, 2024 and 2023. The remaining revenue primarily includes royalty revenue from licensing arrangements and revenue from wafer testing services performed for third parties. See Note 8 for the disaggregation of the Company’s revenue by geographic region and by product family.

     

    The Company sells its products primarily through third-party distributors, value-added resellers, original equipment manufacturers (“OEMs”), original design manufacturers (“ODMs”) and electronic manufacturing service (“EMS”) providers. For the three months ended September 30, 2024 and 2023, 88% and 77%, respectively, of the Company’s product sales were made through distribution arrangements. For the nine months ended September 30, 2024 and 2023, 87% and 79%, respectively, of the Company’s product sales were made through distribution arrangements. These distribution arrangements contain enforceable rights and obligations specific to those distributors and not the end customers. Purchase orders, which are generally governed by sales agreements or the Company’s standard terms of sale, set the final terms for unit price, quantity, shipping and payment agreed between the Company and the customer. The Company considers purchase orders to be the contracts with customers. The unit price as stated on the purchase orders is considered the observable, stand-alone selling price for the arrangements.

     

    The Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods or services to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company excludes taxes assessed by government authorities, such as sales taxes, from revenue.

     

    Product sales consist of a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue from distributors and direct end customers when the following events have occurred: (a) the Company has transferred physical possession of the products, (b) the Company has a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. In accordance with the shipping terms specified in the contracts, these criteria are generally met when the products are shipped from the Company’s facilities (such as the “Ex Works” shipping term) or delivered to the customers’ locations (such as the “Delivered Duty Paid” shipping term).

     

    Under certain consignment agreements, the Company recognizes revenue when the customers consume the products from the consigned inventory locations, at which time control transfers to the customers and the Company issues invoices.

    Table of Contents

     

    Variable Consideration

     

    The Company accounts for price adjustments and stock rotation rights as variable consideration that reduces the transaction price and recognizes that reduction in the same period the associated revenue is recognized. Certain U.S.-based distributors have price adjustment rights when they sell the Company’s products to their end customers at a price that is lower than the distribution price invoiced by the Company. When the Company receives claims from the distributors that products have been sold to the end customers at the lower price, the Company issues the distributors credit memos for the price adjustments. The Company estimates the price adjustments using the expected value method based on an analysis of historical claims, at both the distributor and product level, as well as an assessment of any known trends of product sales mix. Other U.S. distributors and non-U.S. distributors do not have price adjustment rights. The Company records a credit against accounts receivable for the estimated price adjustments, with a corresponding reduction to revenue.

     

    Certain distributors have limited stock rotation rights that permit the return of a small percentage of the previous nine months’ purchases in accordance with the contract terms. The Company estimates the stock rotation returns using the expected value method based on an analysis of historical returns, and the current level of inventory in the distribution channel. The Company records a liability for the stock rotation reserve, with a corresponding reduction to revenue. In addition, the Company recognizes an asset for product returns which represents the right to recover products from the customers related to stock rotations, with a corresponding reduction to cost of revenue.

     

    Contract Balances

     

    Accounts Receivable:

     

    The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied. The Company’s accounts receivables are short-term, with standard payment terms generally ranging from 30 to 90 days. The Company does not require its customers to provide collateral to support accounts receivable. The Company assesses collectability by reviewing accounts receivable on a customer-by-customer basis. To manage credit risk, management performs ongoing credit evaluations of the customers’ financial condition, monitors payment performance, and assesses current economic conditions, as well as reasonable and supportable forecasts of future economic conditions, that may affect collectability of the outstanding receivables. For certain customers, the Company requires standby letters of credit or advance payments prior to shipments of goods. The Company did not recognize any write-offs of accounts receivable or record any allowance for credit losses for the periods presented.

     

    Contract Liabilities:

     

    For customers without credit terms, the Company requires cash payments two weeks before the products are scheduled to be shipped to the customers. The Company records these payments received in advance of performance as customer prepayments within current accrued liabilities. As of September 30, 2024 and December 31, 2023, customer prepayments totaled $6.3 million and $2.8 million, respectively. The increase in the customer prepayment balance for the nine months ended September 30, 2024 resulted from an increase in unfulfilled customer orders for which the Company had received payments. 

     

    Practical Expedients

     

    The Company has elected the practical expedient to expense sales commissions as incurred because the amortization period would have been one year or less.

     

    The Company’s standard payment terms generally require customers to pay 30 to 90 days after the Company satisfies the performance obligations. For those customers who are required to pay in advance, the Company satisfies the performance obligations generally within a quarter. For these reasons, the Company has elected not to determine whether contracts with customers contain significant financing components.

     

    The Company’s unsatisfied performance obligations primarily include products held in consignment arrangements and customer purchase orders for products that the Company has not yet shipped. Because the Company expects to fulfill these performance obligations within one year, the Company has elected not to disclose the amount of these remaining performance obligations.

    3. STOCK-BASED COMPENSATION

     

    2014 Equity Incentive Plan

     

    In April 2013, the Board of Directors adopted the Company’s 2014 Equity Incentive Plan (the “2014 Plan”), which the Company’s stockholders approved in June 2013. In October 2014, the Board of Directors approved certain amendments to the 2014 Plan. The amended 2014 Plan became effective on November 13, 2014, and provided for the issuance of up to 5.5 million shares. In April 2020, the Board of Directors further amended and restated the amended 2014 Plan (the “Amended and Restated 2014 Plan”), which the Company’s stockholders approved in June 2020. The Amended and Restated 2014 Plan became effective on June 11, 2020, and provides for the issuance of up to 10.5 million shares. The Amended and Restated 2014 Plan will cease being available for new awards on June 11, 2030. As of September 30, 2024, 3.9 million shares remained available for future issuance under the Amended and Restated 2014 Plan.

    The intrinsic value related to vested RSUs was $65.7 million and $148.9 million for the three months ended September 30, 2024 and 2023, respectively. The intrinsic value related to vested RSUs was $494.4 million and $388.6 million for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the total intrinsic value of all outstanding RSUs was $1.6 billion, based on the closing stock price of $924.50. As of September 30, 2024, unamortized compensation expense related to all outstanding RSUs was $299.6 million with a weighted-average remaining recognition period of approximately two years.

     

    Time-Based RSUs:

     

    For the nine months ended September 30, 2024, the Compensation Committee granted 31,000 RSUs with service conditions to non-executive employees and non-employee directors. The RSUs generally vest over four years for employees and one year for directors, subject to continued service with the Company.

     

    2024 PSUs:

     

    In February 2024, the Compensation Committee granted 50,000 PSUs to the executive officers, which represent the target number of shares that can be earned based on the degree of achievement of three sets of independent performance goals (“2024 Executive PSUs”). For the first goal, the executive officers can earn up to 300% of the target number of the 2024 Executive PSUs based on the achievement of the Company’s average three-year (2024 through 2026) revenue growth rate in excess of the analog industry’s average three-year revenue growth rate as published by the Semiconductor Industry Association (the “SIA”). For the second goal, the executive officers can earn 100% of the target number of the 2024 Executive PSUs if the Company achieves a reduction in 2026 of 25% global combined Scope 1 and Scope 2 greenhouse gas emissions against the 2022 baseline. For the third goal, the executive officers can earn 50% of the target number of the 2024 Executive PSUs if more than one-third of the Company’s total 2026 revenue in the automotive market is generated from Electronic Vehicle (“EV”) automakers. In addition, for the third goal, the executive officers can earn 50% of the target number of the 2024 Executive PSUs if total 2026 revenue from products enabling EV powertrains and EV 48V systems grows to 200% of the 2023 baseline. For the first goal, a percentage of the 2024 Executive PSUs will fully vest on December 31, 2026, depending on the degree to which the pre-determined goal is met during the performance period. The 2024 Executive PSUs related to the second and the third goal will fully vest on December 31, 2026 if the pre-determined goals are met during the performance period. Assuming the achievement of the highest level of the performance goals, the total stock-based compensation cost for the 2024 Executive PSUs will be $154.3 million. 
     
    In February 2024, the Compensation Committee granted 11,000 PSUs to certain non-executive employees, which represent the target number of shares that can be earned based on the degree of achievement of the Company’s 2025 revenue goals for certain regions or product line divisions, or based on the degree of achievement of the Company’s average two-year (2024 and 2025) revenue growth rate compared against the analog industry’s average two-year revenue growth rate as published by the SIA (“2024 Non-Executive PSUs”). The maximum number of shares that an employee can earn is either 200% or 300% of the target number of the 2024 Non-Executive PSUs, depending on the job classification of the employee. 50% of the 2024 Non-Executive PSUs will vest in the first quarter of 2026 depending on the degree to which the pre-determined goals are met during the performance period. The remaining 2024 Non-Executive PSUs will vest over the following two years on a quarterly basis. Assuming the achievement of the highest level of performance goals, the total stock-based compensation cost for the 2024 Non-Executive PSUs will be $17.7 million. 
     
    The 2024 Executive PSUs and the 2024 Non-Executive PSUs contain a purchase price feature, which requires the employees to pay the Company $30 per share upon vesting of the shares. The $30 purchase price requirement is deemed satisfied and waived if the Company’s stock price on the last trading day of the performance period is $30 higher than the grant date stock price of $632.98. The Company determined the grant date fair value of the 2024 Executive PSUs and the 2024 Non-Executive PSUs using a Monte Carlo simulation model with the following assumptions: stock price of $632.98, simulation term of three years, expected volatility of 49.4%, risk-free interest rate of 4.1%, and expected dividend yield of 0.8%. There is no illiquidity discount because the awards do not contain any post-vesting sales restrictions.

    2004 Employee Stock Purchase Plan (as amended and restated, the “2004 ESPP”)

     

    On August 16, 2023, the 2004 ESPP was amended and restated to, among other changes, provide for the issuance of up to 4.4 million shares of the Company’s common stock. The 2004 ESPP will expire on August 16, 2038.

     

    For the three months ended September 30, 2024 and 2023, 7,000 and 9,000 shares were issued under the 2004 ESPP, respectively. For the nine months ended September 30, 2024 and 2023, 18,000 and 18,000 shares were issued under the 2004 ESPP, respectively. As of September 30, 2024, 4.4 million shares were available for future issuance under the 2004 ESPP.

     

    The intrinsic value of the shares issued was $2.0 million and $0.7 million for the three months ended September 30, 2024 and 2023, respectively. The intrinsic value of the shares issued was $5.4 million and $1.4 million for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the unamortized expense was $1.4 million, which will be recognized through the first quarter of 2025. The Black-Scholes model was used to value the employee stock purchase rights with the following weighted-average assumptions:

    4. ACQUISITION

     

    On January 3, 2024 (the “Acquisition Date”), the Company acquired 100% of the outstanding capital stock of Axign B.V. (“Axign”), a Dutch company that designs and develops class-D audio ICs, targeting applications ranging from portable consumer speakers to automotive and professional-grade multi-speaker systems. Commencing on the Acquisition Date, Axign became a wholly-owned subsidiary of the Company and its results of operations have been included in the Company’s consolidated financial statements.

     

    Purchase Consideration

     

    The purchase consideration was $33.4 million in cash. Cash paid at the Acquisition Date included $3.8 million that is being held in an escrow account for a one-year period as recourse in the event of a breach of Axign’s representations and warranties. 

     

    In connection with the acquisition, the Company incurred $0.4 million in transaction costs that were expensed as incurred and included in selling, general and administrative expenses in the Condensed Consolidated Statements of Operations.

     

    Purchase Price Allocation

     

    The purchase price allocation for Axign is as follows (in thousands):

        13,538  

    Goodwill

        19,860  

    Total net assets acquired

      $ 33,398  

     

    The intangible asset acquired with a finite life includes the core developed technology with an estimated remaining useful life of eight years. The acquired intangible asset with an indefinite life includes an incomplete R&D project that had not reached technological feasibility as of the Acquisition Date. The fair values of the developed technology and the IPR&D were determined using the income approach.

     

    The goodwill arising from the acquisition was primarily attributed to the assembled workforce and synergies that are anticipated to enable the Company to develop solutions with lower power consumption in the consumer and automotive markets using Axign’s digital feedback technology. The goodwill is not expected to be deductible for tax purposes.

    7. NET INCOME PER SHARE

     

    Basic net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding for the period. Diluted net income per share reflects the potential dilution that would occur if outstanding securities or other contracts to issue common stock were exercised or converted into shares of common stock, and calculated using the treasury stock method. Contingently issuable shares, including equity awards with performance conditions or market conditions, are considered outstanding shares of common stock and included in the basic net income per share as of the date that all necessary conditions to earn the awards have been satisfied. Prior to the end of the contingency period, the number of contingently issuable shares included in the diluted net income per share is based on the number of shares, if any, that would be issuable under the terms of the arrangement at the end of the reporting period.

     

    The Company’s RSUs contain forfeitable rights to receive cash dividend equivalents, which are accumulated and paid to the employees when the underlying RSUs vest. Dividend equivalents accumulated on the underlying RSUs are forfeited if the employees do not fulfill the requisite service requirement and, as a result, the awards do not vest. Accordingly, these awards are not treated as participating securities in the net income per share calculation.

     

    The following table sets forth the computation of basic and diluted net income per share (in thousands, except per-share amounts):

    Stock Repurchase Program
     
    In October 2023, the Board of Directors approved a stock repurchase program authorizing the Company to repurchase up to $640.0 million in the aggregate of its common stock through October 29, 2026. Shares are retired upon repurchase. The Company repurchased 6,000 and 19,000 shares of its common stock for an aggregate purchase price of $5.5 million and $14.2 million during the three and nine months ended September 30, 2024, respectively.
     
    Stock repurchased under the program may be made through open market repurchases, privately negotiated transactions or other structures in accordance with applicable state and federal securities laws, at times and in amounts as management deems appropriate. The timing and the number of any repurchased common stock will be determined by the Company’s management based on its evaluation of market conditions, legal requirements, share price, and other factors. The repurchase program does not obligate the Company to purchase any particular number of shares, and may be suspended, modified, or discontinued at any time without prior notice.
     
    The U.S. Inflation Reduction Act of 2022 requires a 1% excise tax based on the value of certain stock repurchases in excess of stock issued for employee compensation made after December 31, 2022. This provision did not have an impact on the Company’s condensed consolidated financial statements for the three and nine months ended September 30, 2024.

    8. SEGMENT, SIGNIFICANT CUSTOMERS AND GEOGRAPHIC INFORMATION

     

    The Company operates in one reportable segment that includes the design, development, marketing and sale of high-performance, semiconductor-based power electronics solutions for the enterprise data, storage and computing, automotive, communications, consumer and industrial markets. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company derives a majority of its revenue from sales to customers located outside North America, with geographic revenue based on the customers’ ship-to locations.

     

    The Company sells its products primarily to third-party distributors and value-added resellers, and directly to OEMs, ODMs and EMS providers. The following table summarizes those customers with sales equal to 10% or more of the Company’s total revenue:

    Distributor C

      *   11%  *   10%

     


    * Represents less than 10%

     

    The Company’s agreements with these third-party customers were made in the ordinary course of business and may be terminated with or without cause by these customers with advance notice. Although the Company may experience a short-term disruption in the distribution of its products and a short-term decline in revenue if its agreement with any of the distributors were terminated, the Company believes that such termination would not have a material adverse effect on its financial statements because it would be able to engage alternative distributors, resellers and other distribution channels to deliver its products to end customers within a short period following any termination of the agreement with a distributor.

     

    The following table summarizes those customers with accounts receivable equal to 10% or more of the Company’s total accounts receivable:

    9. COMMITMENTS AND CONTINGENCIES

     

    Product Warranties

     

    The Company generally provides either a one- or two-year warranty against defects in materials and workmanship and will repair the products, provide replacements at no charge to customers or issue a refund. As they are considered assurance-type warranties, the Company does not account for them as separate performance obligations. Warranty reserve requirements are generally based on a specific assessment of the products sold with warranties when a customer asserts a claim for warranty or for a product defect.

     

    The changes in warranty reserves are as follows (in thousands):

    Changes in liability for pre-existing warranties result from changes in estimates for warranties issued in prior periods.

     

    Purchase Commitments

     

    The Company has outstanding purchase obligations with its suppliers and other parties that require the purchases of goods or services. The purchase obligations primarily consist of wafer and other inventory purchases, assembly and other manufacturing services, construction of manufacturing and R&D facilities, purchases of production and other equipment, and license arrangements.

     

    In May 2022, the Company entered into a long-term supply agreement in order to secure manufacturing production capacity for silicon wafers over a four-year period. As of September 30, 2024, the Company had remaining prepayments under this agreement of $120.0 million, of which $60.0 million was classified as short-term.

    Litigation

     

    The Company is a party to actions and proceedings in the ordinary course of business, including challenges to the enforceability or validity of its intellectual property, claims that the Company’s products infringe on the intellectual property rights of others, and employment matters. The Company may also be subject to litigation initiated by its stockholders. These proceedings often involve complex questions of fact and law and may require the expenditure of significant funds and the diversion of other resources to prosecute and defend. The Company defends itself vigorously against any such claims. As of September 30, 2024, there were no material pending legal proceedings to which the Company was a party.

    An impairment exists when the fair value of an investment is less than its amortized cost basis. As of September 30, 2024 and December 31, 2023, the Company did not consider the impairment of its investments to be a result of credit losses. The Company typically invests in highly rated securities, with the primary objective of minimizing the potential risk of principal loss. The Company’s investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer. When evaluating a debt security for impairment, management reviews factors such as the Company’s intent to sell, or whether it will more likely than not be required to sell, the security before recovery of its amortized cost basis, the extent to which the fair value of the security is less than its cost, the financial condition of the issuer and the credit quality of the investment.

    11. FAIR VALUE MEASUREMENTS

     

    Fair Value Hierarchy

     

    The Company has estimated the fair value of its financial assets by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

     

    ● Level 1 —includes instruments with quoted prices in active markets for identical assets.
    ● Level 2 —includes instruments for which the valuations are based upon quoted market prices in active markets involving similar assets or inputs other than quoted prices that are observable for the assets. The market inputs used to value these instruments generally consist of market yields, recently executed transactions, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Pricing sources may include industry standard data providers, security master files from large financial institutions, and other third-party sources used to determine a daily market value.
    ● Level 3 —includes instruments for which the valuations are based on inputs that are unobservable and significant to the overall fair value measurement.

    14. INCOME TAXES

     

    The income tax provision or benefit for interim periods is generally determined using an estimate of the Company’s annual effective tax rate and adjusted for discrete items, if any, in the relevant period. Each quarter the estimate of the annual effective tax rate is updated, and if the Company’s estimated tax rate changes, a cumulative adjustment is made.

     

    The income tax expense for the three months ended September 30, 2024 was $29.9 million, or 17.1% of pre-tax income. The income tax expense for the nine months ended September 30, 2024 was $66.0 million, or 16.4% of pre-tax income. The effective tax rates were lower than the federal statutory rate of 21% primarily due to foreign income from the Company’s subsidiaries in Bermuda and China being taxed at lower statutory tax rates, and excess tax benefits from stock-based compensation. The decrease in the effective tax rates relative to the federal statutory rate was partially offset by the inclusion of the global intangible low-taxed income (“GILTI”) tax. 

     

    The income tax expense for the three months ended September 30, 2023 was $16.7 million, or 12.1% of pre-tax income. The income tax expense for the nine months ended September 30, 2023 was $55.8 million, or 14.5% of pre-tax income. The effective tax rates were lower than the federal statutory rate of 21% primarily due to foreign income from the Company’s subsidiaries in Bermuda and China being taxed at lower statutory tax rates, and excess tax benefits from stock-based compensation. The decrease in the effective tax rates relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax.

     

    On December 27, 2023, the Bermuda Corporate Income Tax Act of 2023 (the “Bermuda CIT Act”) was enacted and signed into law. It includes a 15% CIT applicable to Bermuda businesses that are multinational enterprises (“MNE”) with annual revenue of €750M or more beginning in 2025. The Bermuda CIT Act also includes an Economic Transition Adjustment (“ETA”) that requires MNEs to revalue their assets and liabilities, excluding goodwill, at their fair value as of September 30, 2023. There is an election to opt out of the ETA. As the Bermuda CIT Act is not effective until January 1, 2025, the Company is evaluating whether or not to adopt this ETA. Based on the information available, the Company has not recorded any changes to income tax expense related to the Bermuda CIT Act as of September 30, 2024.

     

    In September 2024, a subsidiary of the Company was granted a tax credit with a ten-year life by a foreign jurisdiction. The tax credit may be utilized beginning in tax year 2025 to offset income tax liabilities in that jurisdiction, subject to various criteria as outlined by the granting authorities. As of September 30, 2024, the Company has evaluated the sources of income necessary to benefit from the tax credit and has determined that it currently does not meet the more likely than not criteria for realization of this deferred tax asset. As a result, the Company has recorded a full valuation allowance on this deferred tax asset. The Company is evaluating the steps necessary, some of which are not within its immediate control, to generate sufficient future taxable income in the required jurisdiction and will reassess the realizability of this deferred tax asset each reporting period.

    16. DIVIDENDS AND DIVIDEND EQUIVALENTS

     

    Cash Dividend Program

     

    The Company has a dividend program approved by its Board of Directors, pursuant to which the Company intends to pay quarterly cash dividends on its common stock. Based on the Company’s historical practice, stockholders of record as of the last business day of the quarter are entitled to receive the quarterly cash dividends when and if declared by the Board of Directors, which are payable to the stockholders in the following month. The Board of Directors declared the following cash dividends (in thousands, except per-share amounts):

     

       

    Three Months Ended September 30,

       

    Nine Months Ended September 30,

    2023

     

    Dividend declared per share

      $ 1.25     $ 1.00     $ 3.75     $ 3.00  

    Total amount

      $ 60,974     $ 47,832     $ 182,680     $ 142,692  

     

    As of September 30, 2024 and December 31, 2023, accrued dividends totaled $61.0 million and $47.9 million, respectively.

     

    The declaration of any future cash dividends is at the discretion of the Board of Directors and will depend on, among other things, the Company’s financial condition, results of operations, capital requirements, business conditions, and other factors that the Board of Directors may deem relevant, as well as a determination that cash dividends are in the best interests of the Company’s stockholders.

     

    The Company anticipates that cash used for future dividend payments will come from its domestic cash, cash generated from ongoing U.S. operations, and cash repatriated from its Bermuda subsidiary. The Company also anticipates that earnings from other foreign subsidiaries will continue to be indefinitely reinvested.

     

    Cash Dividend Equivalent Rights

     

    The Company’s RSUs contain rights to receive cash dividend equivalents, which entitle employees who hold RSUs to the same dividend value per share as holders of common stock. The dividend equivalents are accumulated and paid to the employees when the underlying RSUs vest. Dividend equivalents accumulated on the underlying RSUs are forfeited if the employees do not fulfill the requisite service requirement and, as a result, the awards do not vest. As of September 30, 2024 and December 31, 2023, accrued dividend equivalents totaled $5.8 million and $11.9 million, respectively.

    Overview

     

    We are a fabless global company that provides high-performance, semiconductor-based power electronics solutions. MPS’s mission is to reduce energy and material consumption to improve all aspects of quality of life and create a sustainable future. Founded in 1997 by our CEO Michael Hsing, MPS has three core strengths: deep system-level knowledge, strong semiconductor design expertise, and innovative proprietary technologies in the areas of semiconductor processes, system integration, and packaging. These combined advantages are designed to enable MPS to deliver reliable, compact, and monolithic solutions that are highly energy-efficient, cost-effective, and environmentally responsible while providing a consistent return on investment to our stockholders.
     
    We operate in the cyclical semiconductor industry. We are subject to industry downturns, but we have targeted product and market areas that we believe have the ability to offer above average industry performance over the long term. Historically, our revenue has generally been higher in the second half of the year than in the first half although various factors, such as market conditions and the timing of key product introductions, could impact this trend.
     
    We work with third parties to manufacture and assemble our ICs. This has enabled us to limit our capital expenditures and fixed costs, while focusing our engineering and design resources on our core strengths.
     
    Following the introduction of a product, our sales cycle generally takes a number of quarters after we receive an initial customer order for a new product to ramp up. Typical supply chain lead times for orders are generally 16 to 26 weeks. These factors, combined with the fact that our customers can cancel or reschedule orders without significant penalty to the customer, make the forecasting of our orders, revenue and expenses difficult.

     

    We derive most of our revenue from sales through distribution arrangements and direct sales to customers in Asia, where our products are incorporated into end-user products. Our revenue from sales to customers in Asia was 94% and 89% of our total revenue for the three months ended September 30, 2024 and 2023, respectively, and 93% and 86% of our total revenue for the nine months ended September 30, 2024 and 2023, respectively. Our revenue from indirect sales to one customer, which primarily comprised power management solutions for artificial intelligence (“AI”) applications, was 15% and 12% of our total revenue for the three months ended September 30, 2024 and 2023, respectively, and 18% and 7% of our total revenue for the nine months ended September 30, 2024 and 2023, respectively.

     

    We derive a majority of our revenue from the sales of our DC to DC converter products which serve the enterprise data, storage and computing, automotive, communications, consumer and industrial markets. We believe our ability to achieve revenue growth will depend, in part, on our ability to develop new products, enter new market segments, gain market share, manage litigation risk, diversify our customer base and continue to secure manufacturing capacity.

     

    Macroeconomic Conditions and Regulations

     

    The semiconductor industry has historically been impacted by various macro-economic challenges including fluctuations in consumer spending, fluctuations in demand for semiconductors, rising inflation, increased interest rates, and fluctuations in currency rates. We remain cautious in light of continued challenging macroeconomic conditions and will continue to monitor the potential impact on our operations. The extent and duration of the direct and indirect impact of macroeconomic events on our business, results of operations and overall financial position remain uncertain and depend on future developments.
     

    We closely monitor changes to export control laws, trade regulations and other trade requirements. To date, no restrictions have had a material impact on our revenue and operations. We will continue to monitor any changes to export control laws, trade regulations and other trade requirements and are committed to complying with all applicable trade laws, regulations and other requirements.

     

    Critical Accounting Policies and Estimates

     

    In preparing our condensed consolidated financial statements in accordance with GAAP, we are required to make estimates, assumptions and judgments that affect the amounts reported in our financial statements and the accompanying disclosures. Estimates and judgments used in the preparation of our condensed consolidated financial statements are, by their nature, uncertain and unpredictable, and depend upon, among other things, many factors outside of our control, including demand for our products, economic conditions and other current and future events, such as macroeconomic factors, including the impact of global economic uncertainties, Russia-Ukraine conflict and the Middle East conflict. Actual results could differ from these estimates and assumptions, and any such differences may be material to our condensed consolidated financial statements.

    Revenue for the three months ended September 30, 2024 was $620.1 million, an increase of $145.2 million, or 30.6%, from $474.9 million for the three months ended September 30, 2023. The increase in revenue was primarily due to higher shipment volume.

     

    For the three months ended September 30, 2024, revenue from the enterprise data market increased $85.5 million, or 86.4%, from the same period in 2023. This increase was primarily due to higher sales of our power management solutions for AI applications. Revenue from the storage and computing market for the three months ended September 30, 2024 increased $14.5 million, or 11.2%, from the same period in 2023. This increase was primarily due to higher sales of commercial notebook and storage applications. Third quarter 2024 automotive revenue increased $16.2 million, or 17.0%, from the same period in 2023. This increase was primarily due to higher sales of applications supporting advanced driver assistance systems and lighting, partially offset by lower sales of applications supporting infotainment. Revenue from the communications market increased $25.1 million, or 53.6%, from the same period in 2023. This increase was primarily driven by higher demand for infrastructure related products and wireless applications. Third quarter 2024 revenue from the consumer market increased $2.0 million, or 3.3%, from the same period in 2023.  Revenue from the industrial market increased $1.9 million, or 4.5%, from the same period in 2023. 

     

    Revenue for the nine months ended September 30, 2024 was $1,585.4 million, an increase of $218.3 million, or 16.0%, from $1,367.1 million for the nine months ended September 30, 2023. The increase in revenue was primarily due to higher average selling prices resulting primarily from product mix.

     

    For the nine months ended September 30, 2024, revenue from the enterprise data market increased $327.3 million, or 168.6%, from the same period in 2023. This increase was primarily due to higher sales of our power management solutions for AI applications. Revenue from the storage and computing market for the first nine months of 2024 decreased $8.8 million, or 2.3%, from the same period in 2023. This decrease was primarily due to lower sales of storage, graphic card and other applications, partially offset by higher sales of commercial notebooks. Revenue from the automotive market for the first nine months of 2024 decreased $19.3 million, or 6.3%, from the same period in 2023. This decrease was primarily due to lower sales of applications supporting infotainment, body electronics and USB connectors, partially offset by higher sales of applications supporting advanced driver assistance systems. Revenue from the communications market decreased $1.9 million, or 1.2%, from the same period in 2023. For the nine months ended September 30, 2024, consumer revenue decreased $46.2 million, or 24.2%, from the same period in 2023. This decrease was broad-based and primarily driven by lower sales of products for gaming, home appliances and mobile devices. Revenue from the industrial market decreased $32.8 million, or 23.5%, from the same period in 2023. This decrease was mainly driven by lower sales of products related to industrial meter, security and instrumentation applications.

The $65.4 million increase in cost of revenue was primarily driven by higher shipment volume, particularly of power management solutions for AI applications.

     

    Gross margin was 55.4% for the three months ended September 30, 2024, compared with 55.5% for the three months ended September 30, 2023. The decrease in gross margin was mainly driven by an increase in inventory write-downs as a percentage of revenue, partially offset by lower warranty expenses as a percentage of revenue and product mix.

     

    Cost of revenue was $709.0 million, or 44.7% of revenue, for the nine months ended September 30, 2024, and $597.1 million, or 43.7% of revenue, for the nine months ended September 30, 2023. The $111.9 million increase in cost of revenue was primarily driven by higher average costs due to product mix.

     

    Gross margin was 55.3% for the nine months ended September 30, 2024, compared with 56.3% for the nine months ended September 30, 2023.

    Other Income, Net

     

    Other income, net, was $10.3 million for the three months ended September 30, 2024, compared with $2.3 million for the three months ended September 30, 2023. The increase in other income was primarily due to an increase in amortization of discount on available-for-sale securities, and an increase in income related to changes in the value of deferred compensation plan investments. 

     

    Other income, net, was $27.3 million for the nine months ended September 30, 2024, compared with $14.1 million for the nine months ended September 30, 2023. The increase in other income was primarily due to an increase in amortization of discount on available-for-sale securities, and an increase in income related to changes in the value of deferred compensation plan investments, partially offset by an increase in charitable contributions. 

     

    Income Tax Expense

     

    The income tax provision for interim periods is generally determined using an estimate of our annual effective tax rate and adjusted for discrete items, if any, in the relevant period. Each quarter the estimate of the annual effective tax rate is updated, and if our estimated tax rate changes, a cumulative adjustment is made.

     

    The income tax expense for the three months ended September 30, 2024 was $29.9 million, or 17.1% of pre-tax income. The income tax expense for the nine months ended September 30, 2024 was $66.0 million, or 16.4% of pre-tax income. The effective tax rates were lower than the federal statutory rate of 21% primarily due to foreign income from our subsidiaries in Bermuda and China being taxed at lower statutory tax rates, and excess tax benefits from stock-based compensation. The decrease in the effective tax rates relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax.

     

    The income tax expense for the three months ended September 30, 2023 was $16.7 million, or 12.1% of pre-tax income. The income tax expense for the nine months ended September 30, 2023 was $55.8 million, or 14.5% of pre-tax income. The effective tax rates were lower than the federal statutory rate of 21% primarily due to foreign income from our subsidiaries in Bermuda and China being taxed at lower statutory tax rates, and excess tax benefits from stock-based compensation. The decrease in the effective tax rates relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax.

     

    The Organization for Economic Co-operation and Development enacted model rules for a new global minimum tax framework, also known as Pillar Two, and certain governments globally have enacted, or are in the process of enacting, legislation considering these model rules. These rules did not have a material impact on our taxes for the three and nine months ended September 30, 2024.

     

    In December 2023, the Bermuda CIT Act was enacted and signed into law. See Note 14 for further details.

     

    In September 2024, one of our subsidiaries was granted a tax credit with a ten-year life by a foreign jurisdiction. The tax credit may be utilized beginning in tax year 2025 to offset income tax liabilities in that jurisdiction, subject to various criteria as outlined by the granting authorities. As of September 30, 2024, we have evaluated the sources of income necessary to benefit from the tax credit and have determined that we currently do not meet the more likely than not criteria for realization of this deferred tax asset. As a result, we have recorded a full valuation allowance on this deferred tax asset. We are evaluating the steps necessary, some of which are not within our immediate control, to generate sufficient future taxable income in the required jurisdiction and will reassess the realizability of this deferred tax asset each reporting period. A release of the valuation allowance could result in a significant one-time noncash tax benefit.

As of September 30, 2024, $506.5 million of cash and cash equivalents and $725.5 million of short-term investments were held by our international subsidiaries. We have repatriated and will likely repatriate cash from our Bermuda subsidiary to fund our expenditures. We anticipate that earnings from other foreign subsidiaries will continue to be indefinitely reinvested.

    For the nine months ended September 30, 2024, the $135.8 million increase in cash provided by operating activities compared to the same period in 2023 was primarily due to increased accounts receivable collections and the collection of $50.0 million of other receivables related to a long-term wafer supply agreement, partially offset by increased inventory purchases. This increase was also affected by changes in other working capital.

     

    For the nine months ended September 30, 2024, the $83.4 million increase in cash used in investing activities compared to the same period in 2023 was primarily due to an increase of $37.2 million in purchases of property and equipment and the $33.3 million acquisition in the nine months ended September 30, 2024.

     

    For the nine months ended September 30, 2024, the $57.5 million increase in cash used in financing activities compared to the same period in 2023 was primarily due to an increase of $43.5 million in dividend and dividend equivalent payments.

    Cash Requirements

     

    Although consequences of economic uncertainties and macroeconomic conditions and other factors could adversely affect our liquidity and capital resources in the future, and our cash requirements may fluctuate based on the timing and extent of many factors such as those discussed above, we believe that our balances of cash, cash equivalents and short-term investments of $1,462.4 million as of September 30, 2024, along with cash generated by ongoing operations, will be sufficient to satisfy our liquidity requirements for the next 12 months and beyond.

     

    Our material cash requirements include the following contractual and other obligations:

     

    Purchase Obligations

     

    Purchase obligations represent commitments to our suppliers and other parties requiring the purchases of goods or services. Our purchase obligations primarily consist of wafer and other inventory purchases, assembly and other manufacturing services, construction of manufacturing and R&D facilities, purchases of production and other equipment, and license arrangements.

     

    In May 2022, we entered into a long-term supply agreement in order to secure manufacturing production capacity for silicon wafers over a four-year period. As of September 30, 2024, we had remaining prepayments under this agreement of $120.0 million, of which $60.0 million was classified as short-term.

     

    As of September 30, 2024, total estimated future unconditional purchase commitments to all suppliers and other parties, net of the $120.0 million prepayment, were $586.9 million, of which $470.9 million was classified as short-term.

     

    Transition Tax Liability

     

    The transition tax liability represents the one-time, mandatory deemed repatriation tax imposed on previously deferred foreign earnings under the U.S. Tax Cuts and Jobs Act enacted in December 2017 (the “2017 Tax Act”). As permitted by the 2017 Tax Act, we have elected to pay the tax liability in installments on an interest-free basis through 2025. As of September 30, 2024, the remaining liability totaled $6.2 million, all of which was classified as short-term.

     

    Operating Leases

     

    Operating lease obligations represent the undiscounted remaining lease payments primarily for our leased facilities and equipment. As of September 30, 2024, these obligations totaled $16.3 million, of which $2.8 million was classified as short-term.

     

    Capital Return to Stockholders
     
    In October 2023, our Board of Directors approved a stock repurchase program authorizing us to repurchase up to $640.0 million in the aggregate of our common stock through October 29, 2026. Shares are retired upon repurchase. We repurchased 6,000 and 19,000 shares of our common stock for an aggregate purchase price of $5.5 million and $14.2 million during the three and nine months ended September 30, 2024, respectively. As of September 30, 2024, $622.1 million remained available for future repurchases under the program.

     

    We currently have a dividend program approved by our Board of Directors, pursuant to which we intend to pay quarterly cash dividends on our common stock. Based on our historical practice, stockholders of record as of the last business day of the quarter are entitled to receive the quarterly cash dividends when and if declared by the Board of Directors, which are payable to the stockholders in the following month. As of September 30, 2024, accrued dividends totaled $61.0 million. The declaration of any future cash dividends is at the discretion of our Board of Directors and will depend on, among other things, our financial condition, results of operations, capital requirements, business conditions and other factors that our Board of Directors may deem relevant, as well as a determination that cash dividends are in the best interests of our stockholders.

     

    Other Long-Term Obligations

     

    Other long-term obligations primarily include payments for deferred compensation plan liabilities and accrued dividend equivalents. As of September 30, 2024, these obligations totaled $88.3 million.

    Item 3. Quantitative and Qualitative Disclosures About Market Risk

     

    For a discussion of market risks, refer to Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” in our Annual Report on Form 10-K for the year ended December 31, 2023. During the three and nine months ended September 30, 2024, there were no material changes or developments that would have materially altered, or were reasonably likely to materially alter, the market risk assessment performed as of December 31, 2023.

     

     

    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 pursuant to Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934 as of the end of the period covered by this Quarterly Report on Form 10-Q.
     
    Based on this evaluation, and due to the finding of the material weakness described below, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2024, our disclosure controls and procedures were not effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms.

     

    As previously reported in our Annual Report on Form 10-K for the year ended December 31, 2023, during the year-end financial reporting process of fiscal year 2023, a material weakness was identified in internal control over financial reporting within the Company’s demand forecast process regarding excess and obsolete inventory. The material weakness resulted from ineffective design of the controls related to management’s review and documentation of the Company’s inventory demand information and other assumptions used to determine the inventory carrying value adjustments necessary to record such quantities at the lower of their cost or net realizable value.
     
    A material weakness is a deficiency, or a combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis. This material weakness did not result in a misstatement to the audited consolidated financial statements for the year ended December 31, 2023. 
     
    Notwithstanding the material weakness in internal control over financial reporting described above, management believes and has concluded that the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with GAAP. 
     
    Ongoing Remediation of Previously Identified Material Weakness
     
    With respect to the material weakness described above, management, under the oversight of the Audit Committee, has implemented measures designed to ensure that control deficiencies contributing to the material weakness are remediated, such that these controls are designed, implemented, and operating effectively. However, the weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. The Company will monitor the effectiveness of its remediation plan and refine its remediation plan as appropriate.
         
    Changes in Internal Control over Financial Reporting
     
    As described above, we are taking steps to remediate the material weakness in our internal control over financial reporting. Other than in connection with the remediation process described above, no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the quarter ended September 30, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

     

    Limitations on Effectiveness of Controls and Procedures

     

    In designing and evaluating the disclosure controls and procedures, management recognizes that any set of controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

    PART II. OTHER INFORMATION

     

     

    Item 1. Legal Proceedings

     

    We are a party to actions and proceedings in the ordinary course of business, including challenges to the enforceability or validity of our intellectual property, claims that our products infringe on the intellectual property rights of others, and employment matters. We may also be subject to litigation initiated by our stockholders. These proceedings often involve complex questions of fact and law and may require the expenditure of significant funds and the diversion of other resources to prosecute and defend. We defend ourselves vigorously against any such claims. As of September 30, 2024, there were no material pending legal proceedings to which we were a party.

     

     

    Item 1A. Risk Factors

     

    The Company’s business, reputation, results of operations, financial condition and stock price can be affected by a number of factors, whether currently known or unknown, including those described in Part I, Item 1A of the Annual Report on Form 10-K for the year ended December 31, 2023 under the heading “Risk Factors.” When any one or more of these risks materialize from time to time, the Company’s business, reputation, results of operations, financial condition and stock price can be materially and adversely affected. There have been no material changes to the Company’s risk factors since the filing of the Annual Report on Form 10-K for the year ended December 31, 2023.

    In October 2023, our Board of Directors approved a stock repurchase program authorizing us to repurchase up to $640.0 million in the aggregate of our common stock through October 29, 2026. Shares are retired upon repurchase. We repurchased 6,000 and 19,000 shares of our common stock for an aggregate purchase price of $5.5 million and $14.2 million during the three and nine months ended September 30, 2024, respectively.
     
    Stock repurchases under the program may be made through open market repurchases, privately negotiated transactions or other structures in accordance with applicable state and federal securities laws, at times and in amounts as management deems appropriate. The timing and the number of shares of any repurchased common stock will be determined by our management based on the evaluation of market conditions, legal requirements, stock price, and other factors. The repurchase program does not obligate us to purchase any particular number of shares and may be suspended, modified, or discontinued at any time without prior notice.
