NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. BASIS OF PRESENTATION
The accompanying unaudited condensed consolidated financial statements of Monolithic Power Systems, Inc., a Delaware corporation, and its wholly owned subsidiaries (the “Company” or “MPS”) have been prepared 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 (“U.S. GAAP”) have been condensed or omitted in accordance with these accounting principles, rules and regulations. All intercompany accounts and transactions have been eliminated. 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, 2024, filed with the SEC on March 3, 2025.
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, 2025 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 six months ended June 30, 2025 from 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, 2024.
Use of Estimates
The preparation of financial statements in conformity with U.S. 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 income tax valuation allowances, inventory valuation and stock-based compensation. 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 June 30, 2025
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 is effective for annual periods beginning January 1, 2025. The standard should be applied prospectively but retrospective application is permitted. Adoption of this new guidance will result in expanded disclosures in the Notes to Consolidated Financial Statements.
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which aims to provide more detailed information about the types of expenses in commonly presented expense captions. The guidance will be effective for annual periods beginning January 1, 2027 and interim periods beginning January 1, 2028. The standard can be applied prospectively or retrospectively to any or all prior periods presented in the financial statements. The Company is evaluating the impact of adoption 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. The remaining revenue, which primarily consists of royalty revenue from licensing arrangements and revenue from wafer testing services performed for third parties, was not significant in any of the periods presented. See Note 7 for the disaggregation of the Company’s revenue by geographic region.
The Company sells its products to end customers primarily through third-party distributors and value-added resellers. For each of the three and six months ended June 30, 2025,
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 customers consume products from the consigned inventory locations, at which time control transfers to the customers and the Company issues invoices.
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 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 prices, 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 six 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 receivable 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 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 other accrued liabilities. As of June 30, 2025 and December 31, 2024, customer prepayments totaled $
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
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

6. 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 from contingently issuable shares and calculated using the treasury stock method. Contingently issuable shares, including all types of equity awards, are considered outstanding shares of common stock and included in 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 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 following table sets forth the computation of basic and diluted net income per share (in thousands, except per-share amounts):

7. SEGMENT, SIGNIFICANT CUSTOMERS AND GEOGRAPHIC INFORMATION
The Company operates in reportable segment that includes the design, development, marketing and sale of high-performance, semiconductor-based power electronics solutions for the storage and computing, automotive, enterprise data, communications, consumer, and industrial end markets. The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. Specifically, the CODM uses net income that is reported on the Condensed Consolidated Statements of Operations and cash provided by operating activities reported in the Condensed Consolidated Statements of Cash Flows to decide whether and how much to reinvest profits into core business operations or to return to stockholders in the form of stock repurchases and dividends.
All significant segment expenses have been captured on the face of the Condensed Consolidated Statements of Operations.
The Company sells its products to end customers primarily through third-party distributors and value-added resellers. The following table summarizes those customers with sales equal to 10% or more of the Company’s total revenue for the periods presented:

| Distributor B | % | % | % | % | ||||||||||||
| Distributor C | % | * | % | * | ||||||||||||
*Represents less than 10%
The Company’s agreements with these third-party distributors were made in the ordinary course of business and may be terminated with or without cause by either party 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.

8. COMMITMENTS AND CONTINGENCIES
Product Warranties and Rework
The Company generally provides either a - or -year warranty against defects in materials and workmanship and will repair 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. Historically, the Company’s warranty obligations have not been material. The Company may also incur rework costs associated with product-related claims. The Company accrues for warranty and rework costs upon evaluation of customer specific claims.

An impairment exists when the fair value of an investment is less than its amortized cost basis. As of June 30, 2025 and December 31, 2024, 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.

10. 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. |

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 June 30, 2025 was $
The income tax expense for the three months ended June 30, 2024 was $
In January 2025, the Organization for Economic Co-operation and Development (“OECD”) released new Administrative Guidance on the application of the Global Anti-Base Erosion (“GLoBE”) Model Rules. The Company will continue to evaluate the impact of this release and of other future guidance on the Company’s future global tax provision.
In December 2023, the Bermuda Corporate Income Tax Act of 2023 (the “Bermuda CIT Act”) was enacted and signed into law. The Bermuda CIT Act includes a 15% corporate income tax applicable to Bermuda businesses that are multinational enterprises with annual revenue of €750M or more beginning in 2025. As the Company did not realize material taxable income in Bermuda in the three and six months ended June 30, 2025, no material changes to income tax expense related to the Bermuda CIT Act have been recorded as of June 30, 2025.

| Total amount | $ | $ | $ | $ | ||||||||||||
As of June 30, 2025 and December 31, 2024, accrued cash dividends totaled $
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 certain foreign subsidiaries. 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 underlying RSUs do not vest. As of June 30, 2025 and December 31, 2024, accrued dividend equivalents totaled $
Stock Repurchase Programs
In October 2023, the Board of Directors approved a stock repurchase program authorizing the Company to repurchase up to $
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.
16. SUBSEQUENT EVENT
The budget reconciliation bill H.R.1 was enacted on July 4, 2025.

Overview
We are a fabless global company that provides high-performance, semiconductor-based power electronics solutions. Our 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, we have 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 us 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 allow us to operate at above average industry performance levels 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 incurring a significant penalty, 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 93% of our total revenue for each of the three and six months ended June 30, 2025 and 2024.
We believe our ability to achieve revenue growth will depend, in part, on our ability to develop new products, enter new markets, gain market share, manage litigation risk, diversify our customer base and continue to secure manufacturing capacity.
Macroeconomic Conditions and Regulations
The semiconductor industry is impacted by various macroeconomic challenges including fluctuations in consumer spending, fluctuations in demand for semiconductors, rising inflation, global tariffs and retaliatory measures and announcements regarding same, 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, tariffs, trade regulations and other trade requirements. To date, no restrictions or requirements have had a material impact on our revenue and operations. We believe that our diverse, agile and resilient supply chain is structured in a way to minimize the impact of tariffs; however, such restrictions or requirements can be enacted quickly and unexpectedly and could impact our business in the future. To the extent tariffs, trade regulations or retaliatory measures or announcements regarding same that affect us are implemented, we will seek to take mitigating actions in the near- and medium-term, as necessary, and are committed to complying with all applicable trade laws, regulations and other requirements.
Critical Accounting Estimates
In preparing our condensed consolidated financial statements in accordance with U.S. 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 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, global economic uncertainties, geopolitical tensions and global tariffs and retaliatory measures and announcements regarding same. Actual results could differ from these estimates and assumptions, and any such differences may be material to our condensed consolidated financial statements.
There have been no material changes during the three months ended June 30, 2025 to our critical accounting estimates from the information provided in the “Critical Accounting Estimates” section of Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2024.

Other Income, Net
Other income, net, was $12.2 million for the three months ended June 30, 2025, compared with $7.5 million for the three months ended June 30, 2024. The increase in other income, net was primarily due to a decrease of $5.4 million in charitable commitments, and $4.3 million related to changes in the value of the deferred compensation plan investments, partially offset by a decrease of $3.8 million in amortization of the discount on available-for-sale securities.
Other income, net, was $17.4 million for the six months ended June 30, 2025, compared with $17.1 million for the six months ended June 30, 2024. The increase in other income, net was primarily due to a decrease of $11.3 million in charitable commitments, partially offset by a decrease of $7.2 million in amortization of the discount on available-for-sale securities.
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 June 30, 2025 was $43.3 million, or 24.4% of pre-tax income. The income tax expense for the six months ended June 30, 2025 was $83.4 million, or 23.8% of pre-tax income. The effective tax rates were higher than the federal statutory rate of 21% primarily due to the U.S. impact of foreign earnings and non-deductible stock-based compensation. The higher effective tax rates relative to the federal statutory rate were partially offset by income generated by our subsidiaries in lower tax jurisdictions, foreign tax credits, and U.S. R&D credits.
The income tax expense for the three months ended June 30, 2024 was $23.7 million, or 19.1% of pre-tax income. The income tax expense for the six months ended June 30, 2024 was $36.2 million, or 15.8% of pre-tax income. The effective tax rates were lower than the federal statutory rate of 21% primarily due to lower statutory tax rates at certain of our foreign subsidiaries, and excess tax benefits from stock-based compensation. The lower effective tax rates relative to the federal statutory rate were partially offset by the inclusion of the GILTI tax.
The recent H.R.1 Act that was signed into law on July 4, 2025 introduces significant provisions, including tax cut extensions and modifications to the existing tax framework. We are currently evaluating and will continue to evaluate the impact of these legislative changes on our consolidated financial statements as additional guidance becomes available.
In January 2025, the OECD released new Administrative Guidance on the application of the GLoBE Model Rules. We will continue to evaluate the impact of this release and of other future guidance on our future global tax provision.
In December 2023, the Bermuda CIT Act was enacted and signed into law. See Note 13 for further details.

For the six months ended June 30, 2025, the $105.0 million increase in net cash provided by operating activities compared to the same period in 2024 was primarily due to increased accounts receivable collections, partially offset by increased inventory purchases and changes in other working capital.
The net cash used in investing activities for the six months ended June 30, 2025 was flat compared to the net cash used for the same period in 2024.
For the six months ended June 30, 2025, the $11.7 million increase in net cash used in financing activities compared to the same period in 2024 was primarily due to an increase of $17.5 million in dividend and dividend equivalent payments, partially offset by a decrease in repurchases of common stock.
Cash Requirements
Although consequences of economic uncertainties and macroeconomic conditions, including tariffs and retaliatory measures and announcements regarding same, and other factors could adversely affect our liquidity and capital resources in the future, and 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 $1,146.1 million as of June 30, 2025, 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 June 30, 2025, we had remaining prepayments under this agreement of $60.0 million reported in other current assets on the Condensed Consolidated Balance Sheets.
As of June 30, 2025, total estimated future unconditional purchase commitments to all suppliers and other parties, net of the $60.0 million prepayment, were $449.0 million, of which $397.2 million was due within a year.
Operating Leases
Operating lease obligations represent the undiscounted remaining lease payments primarily for our leased facilities. As of June 30, 2025, these obligations totaled $19.9 million, of which $4.0 million was short-term.
Capital Return to Stockholders
In February 2025, our Board of Directors approved a stock repurchase program authorizing us to repurchase up to $500.0 million of our common stock through February 2028. Shares are retired upon repurchase. We repurchased 3,900 shares of our common stock for an aggregate purchase price of $2.6 million during the three months ended June 30, 2025. No repurchases were made during the three months ended March 31, 2025. As of June 30, 2025, $497.4 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 June 30, 2025, accrued cash dividends totaled $74.7 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 June 30, 2025, these obligations totaled $97.5 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, 2024. During the three and six months ended June 30, 2025, 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, 2024.
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, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2025, our disclosure controls and procedures were designed at a reasonable assurance level and were 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, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
During the quarter ended June 30, 2025, there were no changes in our internal control over financial reporting that would have materially affected, or were 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.
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 are also 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. Based on current information, we do not believe that a material loss from known matters is probable as of June 30, 2025.
On February 4, 2025, a purported class action lawsuit was filed against us and certain of our executives. The lawsuit is captioned Waterford Twp. Gen. Emps. Ret. Sys. v. Monolithic Power Systems, Inc., et al., No. 25-cv-220 (W.D. Wash.) (the “Securities Action”) and alleges that we violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder, by making material misstatements or omissions relating to our business, including with respect to our business relationship with Nvidia. We believe the lawsuit is meritless and intend to defend against it vigorously. Related to the Securities Action, two shareholder derivative suits were also filed, against current – and one former – director, and certain executives, alleging breaches of their fiduciary duties (Miller v. Hsing, et al., No. 25-cv-527 (W.D. Wash.), filed on March 26, 2025, and Roy v. Hsing, et al. No. 25-cv-555 (W.D. Wash.), filed on March 28, 2025, (the “Derivative Litigation”). The Securities Action and Derivative Litigation seek unspecified amounts of damages and/or attorneys’ fees and other relief. The Derivative Litigation is stayed pending developments in the Securities Action.
Our 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 our Annual Report on Form 10-K for the year ended December 31, 2024 under the heading “Risk Factors.” When any one or more of these risks materialize from time to time, our business, reputation, results of operations, financial condition and stock price can be materially and adversely affected. There have been no material changes to our risk factors since the filing of our Annual Report on Form 10-K for the year ended December 31, 2024.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
Issuer Purchases of Equity Securities
In February 2025, our Board of Directors approved a stock repurchase program authorizing us to repurchase up to $500.0 million of our common stock through February 2028. Shares are retired upon repurchase. We repurchased 3,900 shares of our common stock for an aggregate purchase price of $2.6 million during the three months ended June 30, 2025. No repurchases were made during the three months ended March 31, 2025.
The following table represents details of our stock repurchase transactions during the three months ended June 30, 2025:

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.
Item 3. Defaults Upon Senior Securities
None.
Item 4. Mine Safety Disclosures
Not applicable.
Certain of our executive officers and directors have entered into trading plans pursuant to Rule 10b5-1(c) of the Securities Exchange Act of 1934, as amended. A trading plan is a written document that pre-establishes the amounts, prices and dates (or formula for determining the amounts, prices and dates) of future purchases or sales of our common stock, including the sale of shares acquired pursuant to the Monolithic Power Systems, Inc. 2004 Employee Stock Purchase Plan, amended and restated, and upon vesting of RSUs.
During the three months ended June 30, 2025, trading plans intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) were adopted, modified, or terminated, and other written trading arrangements that are not intended to qualify for the Rule 10b5-1(c) affirmative defense were adopted, modified, or terminated.
