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, 2025, filed with the SEC on February 27, 2026.
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, 2026 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 months ended March 31, 2026 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, 2025.
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 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 March 31, 2026
In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 Company will adopt this standard in its Form 10-K for the fiscal year ending December 31, 2027. 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.
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 following is a summary of revenue by geographic region for the periods presented (in thousands):
| Three Months Ended March 31, | ||||||||
| Country or Region | 2026 | 2025 | ||||||
| China | $ | $ | ||||||
| Taiwan | ||||||||
| South Korea | ||||||||
| Southeast Asia | ||||||||
| Europe | ||||||||
| U.S. | ||||||||
| Japan | ||||||||
| Other | ||||||||
| Total | $ | $ | ||||||
The Company sells its products to end customers primarily through third-party distributors and value-added resellers. For the three months ended March 31, 2026 and 2025,
The following table summarizes those customers with sales equal to 10% or more of the Company’s total revenue for the periods presented:
| Three Months Ended March 31, | ||||||||
| Customer | 2026 | 2025 | ||||||
| Distributor A | % | % | ||||||
| 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 these distributors 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 relatively short period following any termination of the agreement with a distributor.
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 upon between the Company and the customer. The Company considers purchase orders to be contracts with the customers. The unit price as stated on the purchase orders is considered the observable, stand-alone selling price for the contracts.
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 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.
The following table summarizes those customers with accounts receivable equal to 10% or more of the Company’s total accounts receivable:
| March 31, | December 31, | |||||||
| Customer | 2026 | 2025 | ||||||
| Distributor A | % | % | ||||||
| Value-added reseller A | % | * | ||||||
| Distributor B | % | % | ||||||
*Represents less than 10%.
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

Equity awards granted to the Company’s executive officers are subject to the tax deduction limitations set by Section 162(m) of the Internal Revenue Code. |
Restricted Stock Units (“RSUs”)
The Company’s RSUs include time-based RSUs, RSUs with performance conditions (“PSUs”) and RSUs with market conditions (“MSUs”). Vesting of awards with performance conditions or market conditions is subject to the achievement of pre-determined performance or market goals and the approval of such achievement by the Compensation Committee of the Board of Directors (the “Compensation Committee”). All awards include service conditions which require continued employment with or service to the Company.
A summary of RSU activity is presented in the table below (in thousands, except per-share amounts):

5. 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 is 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 as if the end of the reporting period were the end of the contingency period.
The following table sets forth the computation of basic and diluted net income per share for the periods presented (in thousands, except per-share amounts):

6. SEGMENT 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, enterprise data, automotive, industrial, communications, and consumer 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.

7. 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 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. The Company accrues for warranty and rework costs upon evaluation of customer specific claims. Historically, the Company’s warranty obligations and rework costs associated with product-related claims have not been material. The estimated amount of product warranty and rework liabilities was $
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.
Total estimated future unconditional purchase commitments to all suppliers and other parties as of March 31, 2026 were as follows (in thousands):

9. 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 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. The Board of Directors declared the following cash dividends for the periods presented (in thousands, except per-share amounts):
| Three Months Ended March 31, | ||||||||
| 2026 | 2025 | |||||||
| Dividend declared per share | $ | $ | ||||||
| Total amount | $ | $ | ||||||
As of March 31, 2026 and December 31, 2025, accrued 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 after the underlying RSUs vest. Dividend equivalents accumulated on the underlying RSUs are forfeited if the underlying RSUs do not vest. As of March 31, 2026 and December 31, 2025, accrued dividend equivalents totaled $
Stock Repurchase Program
In February 2025, 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 shares 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.

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 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.
We work with third parties to manufacture, assemble and test 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 92% and 94% of our total revenue for the three months ended March 31, 2026 and 2025, respectively. 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 the same, increased interest rates, and fluctuations in currency rates. We remain cautious in light of continued challenging global 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. For the three months ended March 31, 2026 and through the date we filed this Quarterly Report on Form 10-Q, 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 the same that affect us are implemented, we will seek to take mitigating actions in the near- and medium-term, as necessary, but there can be no assurance we will be successful. We 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. These factors include demand for our products, economic conditions and other current and future events, such as macroeconomic factors, global economic uncertainties, current and potential global conflicts and global tariffs, export controls and retaliatory measures and announcements regarding the 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 March 31, 2026 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, 2025.

Revenue for the three months ended March 31, 2026 was $804.2 million, an increase of $166.6 million, or 26.1%, from $637.6 million for the three months ended March 31, 2025. The increase in revenue was primarily due to higher shipment volume and higher average selling prices resulting primarily from product mix.
By end market, first quarter 2026 revenue for enterprise data increased $129.9 million, or 97.7%, from the same period in 2025. This increase was primarily due to higher sales of power solutions for artificial intelligence (“AI”) and server applications. Revenue from the storage and computing market of $174.4 million decreased $14.1 million, or 7.5%, from the same period in 2025 primarily due to decreased sales of power solutions for notebooks and graphics cards, partially offset by increased sales of memory and storage applications. First quarter 2026 automotive revenue of $152.3 million increased $7.4 million, or 5.1%, from the same period in 2025. Communications revenue of $111.5 million increased $39.8 million, or 55.5%, from the same period in 2025 due to higher sales of power solutions for optical modules and switches. First quarter 2026 consumer revenue decreased $2.4 million, or 4.2%, from the same period in 2025. Revenue of $48.6 million from the industrial market increased $6.0 million, or 14.2%, from the same period in 2025.
Cost of Revenue and Gross Margin
Cost of revenue primarily consists of costs incurred to manufacture, assemble and test our products, as well as warranty costs, inventory-related and other overhead costs, and stock-based compensation expenses.

Cost of revenue was $359.1 million, or 44.7% of revenue, for the three months ended March 31, 2026, and $284.3 million, or 44.6% of revenue, for the three months ended March 31, 2025. The $74.8 million increase in cost of revenue was primarily driven by product mix and higher shipment volume.
Gross margin was 55.3% for the three months ended March 31, 2026, compared with 55.4% for the three months ended March 31, 2025. The decrease in gross margin was mainly driven by higher warranty expenses as a percentage of revenue, partially offset by lower manufacturing overhead costs as a percentage of revenue.
Research and Development
R&D expenses primarily consist of cash-based compensation and benefits, stock-based compensation and deferred compensation for design and product engineers, expenses related to new product development and supplies, and facilities costs.

The $11.1 million increase in SG&A expenses was primarily driven by a $10.0 million increase in cash-based compensation and benefits, a $5.1 million increase in stock-based compensation related payroll taxes, and a $4.4 million increase in legal expenses, partially offset by an $11.1 million decrease in stock-based compensation.
Other Income, Net
Other income, net, was $6.0 million for the three months ended March 31, 2026, compared with $5.1 million for the three months ended March 31, 2025.

For the three months ended March 31, 2026, the $6.1 million decrease in net cash provided by operating activities compared to the same period in 2025 was primarily due to increased inventory purchases and other changes in working capital, partially offset by increased accounts receivable collections.
For the three months ended March 31, 2026, the $45.2 million decrease in net cash used in investing activities compared to the same period in 2025 was primarily due to $69.2 million higher net purchases of investments, partially offset by $24.1 million higher purchases of property and equipment.
For the three months ended March 31, 2026, the $19.4 million increase in net cash used in financing activities compared to the same period in 2025 was primarily due to an increase of $18.4 million in dividend and dividend equivalent payments.
Cash Requirements
Although consequences of economic uncertainties and macroeconomic conditions, including tariffs and retaliatory measures and announcements regarding the same, and many 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 $1,367.1 million as of March 31, 2026, along with cash generated by ongoing operations, will be sufficient to satisfy our liquidity requirements for the next 12 months.
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.
As of March 31, 2026, total estimated future unconditional purchase commitments to all suppliers and other parties were $588.7 million, of which $557.5 million was due within a year.
Capital Return to Stockholders
In February 2025, our Board of Directors approved a new stock repurchase program authorizing us to repurchase up to $500.0 million of our common stock through February 2028. Shares are retired upon repurchase. The Company did not make any repurchases under this program during the three months ended March 31, 2026. As of March 31, 2026, $493.4 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 March 31, 2026, accrued dividends totaled $98.3 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 deferred compensation plan liabilities and accrued dividend equivalents. As of March 31, 2026, these obligations totaled $99.2 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, 2025.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Interim 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 Interim Chief Financial Officer concluded that, as of March 31, 2026, 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, 2025, during the year-end financial reporting process for fiscal year 2025, the material weakness was identified in internal control over financial reporting related to the accounting for deferred income taxes. We engaged third-party tax service providers in connection with the original determination of the accounting for deferred income taxes associated with a one-time tax incentive granted by a certain foreign jurisdiction. Nevertheless, the internal controls in place with respect to the review of the calculation of deferred income taxes and the related income tax expense (benefit) were not designed appropriately or operating effectively as of March 31, 2026.
Notwithstanding the material weakness in internal control over financial reporting, 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 U.S. 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 material 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. Management expects to remediate the material weakness by the end of fiscal year 2026 and is monitoring the effectiveness of its remediation plan and will refine the plan as appropriate. However, there is no assurance as to when such remediation will be completed.
Changes in Internal Control over Financial Reporting
Except for the remediation measures related to the material weakness described above, there were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2026, 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 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 and management assessment, we do not believe that a material loss from known matters is probable as of March 31, 2026.
On February 4, 2025, a 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. We believe the lawsuit is meritless and currently 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. The shareholder derivative suits have been consolidated under the caption Miller v. Hsing, et al., No. 25-cv-527 (W.D. Wash.), filed on March 26, 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, 2025 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, 2025.
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 did not make any repurchases under this program during the three months ended March 31, 2026.
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 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.
The following table summarizes the adoption of trading plans intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) during the three months ended March 31, 2026:
