Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q includes a number of forward-looking statements that involve many risks and uncertainties. Forward-looking statements are identified by the use of the words “would,” “could,” “will,” “may,” “expect,” “believe,” “should,” “anticipate,” “if,” “future,” “intend,” “plan,” “estimate,” “potential,” “target,” “seek,” or “continue” and similar words and phrases, including the negatives of these terms, or other variations of these terms, that denote future events. These statements reflect our current views with respect to future events and our potential financial performance and are subject to risks and uncertainties that could cause our actual results and financial position to differ materially and/or adversely from what is projected or implied in any forward-looking statements included in this Quarterly Report on Form 10-Q. These factors include, but are not limited to: changes in trade policies among the United States and other countries could reduce demand for end products that incorporate our integrated circuits, which could have a material adverse effect on our revenues and operating results; if demand for our products declines in our major end markets, our net revenues will decline; we do not have long-term contracts with any of our customers and if they fail to place orders for our products, or if they cancel or reschedule orders, our operating results and our business may suffer; our products are sold through distributors, which limits our direct interaction with our end customers, therefore reducing our ability to forecast sales and increasing the complexity of our business; if our products do not penetrate additional markets, our business will not grow as we expect; intense competition in the high-voltage power supply industry may lead to a decrease in our average selling price and reduced sales volume of our products; we depend on third-party suppliers to provide us with wafers for our products, and if they fail to provide us sufficient quantities of wafers, our business may suffer; if we are unable to adequately protect or enforce our intellectual property rights, we could lose market share, incur costly litigation expenses, suffer incremental price erosion or lose valuable assets, any of which could harm our operations and negatively impact our profitability; and the other risk factors described under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, in this Quarterly Report on Form 10-Q and under the caption - “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Quarterly Report on Form 10-Q. We make these forward-looking statements based upon information available on the date of this Quarterly Report on Form 10-Q, and we expressly disclaim any obligation to update or alter any forward-looking statements, whether as a result of new information or otherwise, except as required by laws.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION:

The condensed consolidated financial statements include the accounts of Power Integrations, Inc., a Delaware corporation (the “Company”), and its wholly owned subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.

While the financial information furnished is unaudited, the condensed consolidated financial statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for the fair presentation of the results of operations for the interim periods covered and the financial condition of the Company at the date of the interim balance sheet in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The results for interim periods are not necessarily indicative of the results for the entire year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and the notes thereto for the year ended December 31, 2024, included in its Form 10-K filed on February 7, 2025, with the Securities and Exchange Commission.

2. SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS:

Significant Accounting Policies and Estimates

No material changes have been made to the Company’s significant accounting policies disclosed in Note 2, Significant Accounting Policies and Recent Accounting Pronouncements, of the Company’s financial statements set forth in Item 8 of the Company’s Annual Report on Form 10-K, filed on February 7, 2025, for the year ended December 31, 2024.

Adoption of New Accounting Standards

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements and expand public entities’ segment disclosures in the annual and interim financial statements. The amendment requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and within each reported measure of segment profit or loss, an amount and description of its composition for other segment items and interim disclosures of a reportable segment’s profit or loss and assets. All disclosure requirements of ASU 2023-07 are required for entities with a single reportable segment. The Company adopted the annual disclosure requirements in fiscal year 2024 and the interim disclosure requirements beginning in the first quarter of fiscal year 2025. Refer to Note 12. Segment Reporting.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company does not expect the amendment to have a material impact on its consolidated financial statements upon adoption of the annual disclosure requirements in fiscal year 2025.

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40) which requires additional disclosure of certain costs and expenses, including inventory purchases, employee compensation, selling expense and depreciation expense within the notes to financial statements. The guidance is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the impact that the updated standard will have on its financial statement disclosures.

4. FAIR VALUE MEASUREMENTS:

The FASB established a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices for identical assets in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

The Company’s cash equivalents and short-term marketable securities are classified within Level 1 or Level 2 of the fair-value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.

Total marketable securities	$	14,659	$	(36)	$	3,416	$	(8)	$	18,075	$	(44)

In the three months ended March 31, 2025 and 2024, no unrealized losses on marketable securities were recognized in income.

The Company does not intend to sell and it is unlikely that it will be required to sell the securities prior to their anticipated recovery. The issuers are high quality (investment grade) and the decline in fair value is largely due to changes in interest rates. Additionally, the issuers continue to make timely interest payments on the marketable securities with the fair value expected to recover as they reach maturity.

6. STOCK-BASED COMPENSATION:

The following table summarizes the stock-based compensation expense recognized in accordance with ASC 718-10 for the three months ended March 31, 2025 and 2024:


	Three Months Ended

Stock-based compensation expense in the three months ended March 31, 2025, was approximately $8.7 million, comprising approximately $5.8 million related to restricted stock unit (“RSU”) awards, $2.5 million related to performance-based (“PSU”) awards and long-term performance-based (“PRSU”) awards and $0.4 million related to the Company’s employee stock purchase plan.

Table of Contents

POWER INTEGRATIONS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Stock-based compensation expense in the three months ended March 31, 2024, was approximately $6.4 million, comprising approximately $6.1 million related to RSUs, an immaterial amount related to PSUs and PRSUs and $0.3 million related to the Company’s employee stock purchase plan.

PSU Awards

Under the performance-based awards program, the Company grants awards in the performance year in an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met. The number of shares that are released at the end of the performance year can range from zero to 200% of the target number depending on the Company’s performance. The performance metrics of this program are annual targets consisting of a combination of net revenue, non-GAAP operating income and strategic goals.

As the net revenue, non-GAAP operating income and strategic goals are considered performance conditions, expense associated with these awards, net of estimated forfeitures, is recognized over the service period based on an assessment of the expected achievement of the performance targets. The fair value of these PSUs is determined using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present value of dividends expected to be declared before the awards vest. If the performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed.

In February 2025, it was determined that approximately 66,000 shares subject to the PSUs granted in 2024 vested in aggregate; the shares were released to the Company’s employees and executives in the first quarter of 2024.

A summary of PSUs outstanding as of March 31, 2025 and activity during the three months ended, is presented below:


				Weighted-Average
		Weighted-Average		Remaining	Aggregate
	Shares	Grant Date Fair		Contractual Term	Intrinsic Value
	(In thousands)	Value Per Share		(In years)	(In thousands)

Outstanding at March 31, 2025	102	$	58.05	0.75	$	5,159
Outstanding and expected to vest at March 31, 2025	92			0.75	$	4,638

PRSU Awards

The Company’s PRSU program provides for the issuance of PRSUs which will vest based on the Company’s performance measured against the PRSU program’s established performance targets. PRSUs are granted in an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met. The actual number of shares the recipient receives is determined at the end of a three-year performance period based on results achieved versus the Company’s performance goals, and may range from zero to 200% of the target number. The performance goals for PRSUs granted in fiscal 2023, 2024 and 2025 were based on the Company’s compound annual growth rate (“CAGR”) of revenue as measured against the revenue CAGR of the analog semiconductor industry (“Relative Measure”) or the Company’s revenue growth over as compared to defined targets (“Absolute Measure”) in each case over the respective three-year performance period. Actual vesting of the PRSUs is calculated based on higher achievement under the Relative Measure or the Absolute Measure. Expense associated with these awards, net of estimated forfeitures, is recorded throughout the year based on an assessment of the expected achievement of the performance targets. If the performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed.

In February 2025, it was determined that no shares subject to the PRSUs granted in 2022 vested, thus no shares were released to the Company’s executives.

7. SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES:

Customer Concentration

The Company’s top ten customers accounted for approximately 80% and 77% of net revenues for the three months ended March 31, 2025 and 2024, respectively. A significant portion of these revenues are attributable to sales of the Company’s products to distributors of electronic components. These distributors sell the Company’s products to a broad, diverse range of end users, including original equipment manufacturers (“OEMs”) and merchant power-supply manufacturers. Similarly, merchant power-supply manufacturers sell power supplies incorporating the Company’s products to a broad range of OEMs. Sales to distributors were $75.2 million and $66.4 million in the three months ended March 31, 2025 and 2024, respectively. Direct sales to OEMs and power-supply manufacturers accounted for the remainder.

The following customers represented 10% or more of the Company’s net revenues for the respective periods:

*Total customer revenue was less than 10% of net revenues.

No other customers accounted for 10% or more of the Company’s net revenues in the periods presented.

POWER INTEGRATIONS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash investments and trade receivables. The Company does not have any off-balance-sheet credit exposure related to its customers.

As of March 31, 2025 and December 31, 2024, 86% and 87% of accounts receivable were concentrated with the Company’s top ten customers.

Common Stock Repurchases

As of December 31, 2024, the Company had $48.1 million remaining under its authorized stock-repurchase program. In the three months ended March 31, 2025, the Company purchased approximately 404,000 shares of the Company’s common stock for $23.1 million leaving $25.0 million remaining on the repurchase authorization as of March 31, 2025. In April 2025, the Company utilized the remaining $25.0 million, repurchasing approximately 560,000 shares of its common stock. Subsequently, the Company’s board of directors authorized the use of an additional $50.0 million for the repurchase of the Company’s common stock, with repurchases to be executed according to pre-defined price/volume guidelines. The program has no expiration date. Authorization of future repurchase programs is at the discretion of the Company’s board of directors and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors.

Cash Dividends

In October 2023, the Company’s board of directors declared dividends of $0.20 per share to be paid to stockholders of record at the end of each quarter in 2024.

In October 2024, the Company’s board of directors raised the quarterly cash dividend with the declaration of five cash dividends of $0.21 per share to be paid to stockholders of record at the end of the fourth quarter in 2024 (in lieu of the previously declared dividend of $0.20 per share announced in October 2023) and at the end of each quarter in 2025.

For the three months ended March 31, 2025 and 2024, cash dividends declared and paid were as follows:

9. EARNINGS PER SHARE:

Basic earnings per share are calculated by dividing net income by the weighted-average shares of common stock outstanding during the period. Diluted earnings per share are calculated by dividing net income by the weighted-average shares of common stock and dilutive common equivalent shares outstanding during the period. Dilutive common equivalent shares included in this calculation consist of dilutive shares issuable upon the assumed exercise of outstanding common stock options, the assumed vesting of outstanding restricted stock units, the assumed issuance of awards under the stock purchase plan and contingently issuable performance-based awards, as computed using the treasury stock method.

A summary of the earnings per share calculation is as follows:


	Three Months Ended
	March 31,
(In thousands, except per share amounts)	2025		2024
Basic earnings per share:
Net income	$	8,790	$	3,954
Weighted-average common shares		56,871		56,833
Basic earnings per share	$	0.15	$	0.07
Diluted earnings per share: ⁽¹⁾
Net income	$	8,790	$	3,954
Weighted-average common shares		56,871		56,833
Effect of dilutive awards:
Employee stock plans		252		299
Diluted weighted-average common shares		57,123		57,132
Diluted earnings per share	$	0.15	$	0.07

(1)

The Company includes the shares underlying performance-based awards in the calculation of diluted earnings per share if the performance conditions have been satisfied as of the end of the reporting period and excludes such shares when the necessary conditions have not been met. The Company has excluded the shares underlying the outstanding performance-based awards in the 2025 and 2024 calculations as the shares were not contingently issuable as of the end of the reporting periods.

10. PROVISION FOR INCOME TAXES:

Income-tax expense includes a provision for federal, state and foreign taxes based on the annual estimated effective tax rate applicable to the Company and its subsidiaries, adjusted for certain discrete items which are fully recognized in the period they occur. Accordingly, the interim effective tax rate may not be reflective of the annual estimated effective tax rate.

The Company’s effective tax rate for the three months ended March 31, 2025 and 2024 was 11.1% and 0.5%, respectively. The effective tax rate in these periods were lower than the statutory federal income-tax rate of 21% due to the geographic distribution of the Company’s world-wide earnings in lower-tax jurisdictions and federal research tax credits. In the three months ended March 31, 2025, the Company’s effective tax rate was unfavorably impacted by the recognition of share-based payments and foreign income subject to U.S. tax, known as global intangible low-taxed income (“GILTI”). In the three months ended March 31, 2024, the Company’s effective tax rate was favorably impacted by the recognition of excess tax benefits related to share-based payments and the release of unrecognized tax benefits and unfavorably impacted by foreign income subject to U.S. tax (GILTI). The Company’s primary jurisdiction where foreign earnings are derived is the Cayman Islands, which is a non-taxing jurisdiction. Income earned in other foreign jurisdictions was not material. The Company has not been granted any incentivized tax rates and does not operate under any tax holidays in any jurisdiction.

As of March 31, 2025, the Company maintained a valuation allowance on its California deferred tax assets, New Jersey deferred tax assets and a valuation allowance with respect to its deferred tax assets relating to tax credits in Canada.

POWER INTEGRATIONS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Determining the consolidated provision for income-tax expense, income-tax liabilities and deferred tax assets and liabilities involves judgment. The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates, which involves estimating current tax exposures as well as making judgments regarding the recoverability of deferred tax assets in each jurisdiction. The estimates used could differ from actual results, which may have a significant impact on operating results in future periods.

11. COMMITMENTS:

Supplier Agreements

Under the terms of the Company’s wafer-supply agreements with Seiko Epson Corporation ("Epson") and ROHM Lapis Semiconductor Co., Ltd. ("Lapis"), the wafers purchased from these suppliers are priced in U.S. dollars, with mutual sharing of the impact of fluctuations in the exchange rate between the Japanese yen and the U.S. dollar on future purchases. Each year, the Company’s management and these two suppliers review and negotiate future pricing; the negotiated pricing is denominated in U.S. dollars but is subject to contractual exchange-rate provisions. The fluctuation in the exchange rate is shared equally between the Company and each of these suppliers on future purchases.

12. SEGMENT REPORTING:

The Company is organized and operates as one operating and reportable segment; the design, development, manufacture and marketing of integrated circuits and related components for use primarily in high-voltage power conversion. This determination is based on the management approach which designates internal information regularly available to the Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of determination of the Company’s reportable segments. The Company’s CODM, the Chief Executive Officer, reviews financial information presented on a consolidated basis for the purpose of making operating decisions and assessing financial performance.

The CODM uses net income as the measure of profit or loss to allocate resources and assess performance. The CODM regularly reviews net income as reported on the Company’s consolidated statements of income. Financial forecasts and budget to actual results used by the CODM to assess performance and allocate resources, as well as those used for strategic decisions related to headcount and capital expenditures are also reviewed on a consolidated basis. The CODM considers the impact on net income of the significant segment expenses in the table below when deciding whether to reinvest profits, propose dividends or share repurchase, or pursue strategic mergers and acquisitions.

The measure of segment assets is reported on the balance sheet as total assets. The CODM does not review segment assets at a level other than that presented in the Company’s consolidated balance sheets.

13. LEGAL PROCEEDINGS AND CONTINGENCIES:

From time to time in the ordinary course of business, the Company becomes involved in lawsuits, or customers and distributors may make claims against the Company. In accordance with ASC 450-10, Contingencies, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

On December 18, 2019, CogniPower LLC (“CogniPower”) filed a complaint against a customer of the Company in the United States District Court for the District of Delaware for infringement of two patents; the Company thereafter intervened and sought a declaration of non-infringement with respect to use of the Company’s products. The case was then stayed until February 26, 2024, when the Delaware Court then set a schedule for the remainder of the case, with further proceedings in the coming months, and a trial scheduled in August 2025. On January 16, 2025, CogniPower filed a follow-on complaint against the same customer asserting the same two patents in the United States District Court for the District of Delaware, but no schedule has been set for the follow-on case at this time. The Company believes it has strong claims and defenses with respect to all of CogniPower’s asserted patents and intends to vigorously defend itself against CogniPower’s claims against the Company’s technology, with appeals to follow if necessary.

The Company is unable to predict the outcome of legal proceedings with certainty, and there can be no assurance that the Company will prevail in the above-mentioned unsettled litigations. These litigations, whether or not determined in the Company’s favor or settled, will be costly and will divert the efforts and attention of the Company’s management and technical personnel from normal business operations, potentially causing a material adverse effect on the business, financial condition and operating results. Currently, the Company is not able to estimate a loss or a range of loss for the ongoing litigations disclosed above, however adverse determinations in litigation could result in monetary losses, the loss of proprietary rights, subject the Company to significant liabilities, require the Company to seek licenses from third parties or prevent the Company from licensing the technology, any of which could have a material adverse effect on the Company’s business, financial condition and operating results.

14. INDEMNIFICATIONS:

The Company sells products to its distributors under contracts, collectively referred to as Distributor Sales Agreements (“DSA”). Each DSA contains the relevant terms of the contractual arrangement with the distributor, and generally includes certain provisions for indemnifying the distributor against losses, expenses, and liabilities from damages that may be awarded against the distributor in the event the Company’s products are found to infringe upon a patent, copyright, trademark, or other proprietary right of a third party (“Customer Indemnification”). The DSA generally limits the scope of and remedies for the Customer Indemnification obligations in a variety of industry-standard respects, including, but not limited to, limitations based on time and geography, and a right to replace an infringing product. The Company also, from time to time, has granted a specific indemnification right to individual customers.

The Company believes its internal development processes and other policies and practices limit its exposure related to such indemnifications. In addition, the Company requires its employees to sign a proprietary information and inventions agreement, which assigns the rights to its employees’ development work to the Company. To date, the Company has not had to reimburse any of its distributors or customers for any losses related to these indemnifications and no material claims were outstanding as of March 31, 2025. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases, the Company cannot determine the maximum amount of potential future payments, if any, related to such indemnifications.

15. ACQUISITION:

Odyssey Semiconductor Technologies

On March 12, 2024, the Company agreed to acquire the assets of Odyssey, a U.S. company and a developer of vertical gallium-nitride (“GaN”) transistor technology. The transaction closed on July 1, 2024, at which time all key Odyssey employees joined the Company. Pursuant to the asset purchase agreement, Odyssey sold, transferred and assigned substantially all of its assets to the Company for $9.52 million in cash. The purchase is intended to augment the Company’s development of high-power GaN switching technology.

The acquisition has been accounted for using the acquisition method of accounting in accordance with ASC 805 - Business Combinations. Under the acquisition method of accounting, the total purchase consideration of the acquisition is allocated to the tangible assets and identifiable intangible assets acquired based on their relative fair values. The excess of the purchase consideration over the net tangible and identifiable intangible assets is recorded as goodwill, the amount of which represents the expected benefits to the Company of future technology and the knowledgeable and experienced employees who joined the Company. Goodwill is expected to be deductible over 15 years for tax purposes.

The fair value of in-process research and development was determined based on the cost approach using the Company’s estimate of the costs that would be incurred if a market participant were to create the acquired technology from scratch. The Company considered the number of engineers required, salaries and related benefits, allocated overhead and the development time required to recreate the technology. The Company will record the in-process research and development as an intangible asset with an indefinite life until completion or abandonment of the associated research and development efforts, and will begin amortizing the value over the estimated life of the technology upon completion of development. Consistent with the treatment of other intangible assets with indefinite lives, the Company will test the in-process research and development for impairment on an annual basis or when impairment indicators are present.

Pro forma results of operations for this acquisition have not been presented because they are not material to the Company’s consolidated financial statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis has been prepared as an aid to understanding our financial condition and results of operations. It should be read in conjunction with the condensed consolidated financial statements and the notes to those statements included elsewhere in this Quarterly Report on Form 10-Q, and with the consolidated financial statements and management’s discussion and analysis of our financial condition and results of operations in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 7, 2025. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, and in Part II, Item 1A - “Risk Factors” and elsewhere in this report. See also “Cautionary Note Regarding Forward-Looking Statements” at the beginning of this report.

Overview

We design, develop and market analog and mixed-signal integrated circuits (“ICs”) and other electronic components and circuitry used in high-voltage power conversion. Our products are used in power converters that convert electricity from a high-voltage source to the type of power required for a specified downstream use. In most cases, this conversion entails, among other functions, converting alternating current (“AC”) to direct current (“DC”) or vice versa, reducing or increasing the voltage, and regulating the output voltage and/or current according to the customer’s specifications.

A large percentage of our products are ICs used in AC-DC power supplies, which convert the high-voltage AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating our products are used with all manner of electronic products including appliances, industrial controls, mobile devices such as smartphones, tablets and notebook computers, electronic utility meters, battery-powered tools, and “home-automation,” or “internet of things” applications such as networked thermostats, power strips and security devices. Variations of our power-supply ICs are used for high-voltage power conversion in electric vehicles (“EVs”). We also supply high-voltage LED drivers, which are AC-DC ICs specifically designed for lighting applications that utilize light-emitting diodes, and motor-driver ICs for brushless DC (“BLDC”) motors used in consumer appliances, HVAC systems, ceiling fans and a variety of industrial applications.

We also offer high-voltage gate drivers—either standalone ICs or circuit boards containing ICs, electrical isolation components and other circuitry—used to operate high-voltage switches such as insulated-gate bipolar transistors (“IGBTs”) and silicon-carbide (“SiC”) MOSFETs. These combinations of switches and drivers are used for power conversion in high-power applications (i.e., power levels ranging from approximately 100 kilowatts up to gigawatts) such as industrial motors, solar- and wind-power systems, electric locomotives, EVs and high-voltage DC transmission systems.

Our power-conversion products are distinguished by their “system-level” nature; that is, they incorporate into a single product numerous elements of a power-conversion system including a high-voltage transistor, drivers, advanced control circuitry and, in some cases, a communication link connecting the primary (i.e., input) and secondary (i.e., output) sides of the power converter while maintaining safety isolation to protect the end user from exposure to high voltage. Alternatively, a power converter can be designed and assembled using discrete components purchased from a variety of suppliers.

Our system-level products offer a number of important benefits compared with discrete designs, including: reduced design complexity; smaller size; lower component count, which in turn results in higher reliability and easier sourcing of components; reduced time-to-market; and more efficient use of engineering resources. Our products also reduce the energy consumption of power converters during normal use and in “standby” operation, when the end product is not in use. In addition to the environmental and economic benefits of reduced energy usage, our energy-saving technologies provide a number of benefits to our customers; these include helping them meet the increasingly stringent efficiency standards now in effect for many electronic products, and enabling the elimination of bulky, costly heatsinks used to dissipate the heat produced by wasted electricity. By reducing component count, circuit-board size and the need for heatsinks, our products also contribute to a reduction in materials usage and electronic waste.

While the size of our addressable market fluctuates with changes in macroeconomic and industry conditions, the market has generally exhibited a modest growth rate over time as growth in the unit volume of power converters has been offset to a large degree by reductions in the average selling price of components in this market. Therefore, the growth of our business depends largely on increasing our penetration of the markets that we serve and on further expanding our addressable market. Our growth strategy includes the following elements:

●

Increase the size of our addressable market. Prior to 2010 our addressable market consisted of AC-DC applications with up to about 50 watts of output, a served available market (“SAM”) opportunity of approximately $1.5 billion. Since then, we have expanded our SAM to approximately $4 billion through a variety of means. These include the introduction of products that enable us to address higher-power AC-DC applications (such as our Hiper™ product families), the introduction of LED-driver products, and our entry into the gate-driver market In 2018 we introduced our BridgeSwitch™ motor-driver ICs for BLDC motors, and in 2024 we introduced BridgeSwitch-2, extending the addressable power range of our motor-driver products up to about one horsepower. We have recently introduced a range of products targeting the EV market; we plan to introduce additional products for EVs in the future and expect automotive applications to become a significant portion of our SAM over time.

Also contributing to our SAM expansion has been the emergence of new applications within the power ranges that our products can address. For example, applications such as “smart” utility meters, battery-powered lawn equipment and bicycles, and USB power receptacles (often installed alongside traditional AC wall outlets) can incorporate our products. The increased use of connectivity, LED lighting and other power-consuming electronic features in consumer appliances has also enhanced our SAM.

We have also expanded our SAM through the development of technologies and architectures that increase the value (and therefore the average selling prices) of our products. For example, our InnoSwitch™ ICs integrate circuitry from the secondary, or low-voltage, side of AC-DC power supplies, whereas earlier product families integrated circuitry only on the primary, or high-voltage side. Our InnoMux™ IC families provide up to three DC outputs, eliminating the need for additional power-management circuitry in certain end products requiring multiple voltages while significantly increasing efficiency.

●

Increase our penetration of the markets we serve. We currently address AC-DC applications with power outputs up to approximately 500 watts, gate-driver applications ranging from 100 kilowatts up to gigawatts, and motor-drive applications up to approximately one horsepower. Through our research and development efforts, we seek to introduce more advanced products for these markets offering higher levels of integration and performance compared to earlier products. We also continue to expand our sales and application-engineering staff and our network of distributors, as well as our offerings of technical documentation and design-support tools and services to help customers use our products. These tools and services include our PI Expert™ design software, which we offer free of charge, and our transformer-sample service. In 2022 we launched PowerPros℠, a live online video support service that enables power-supply designers to talk directly with members of our applications engineering team 24 hours a day, six days a week, anywhere in the world.

●

Leverage the performance benefits of our proprietary gallium-nitride (“GaN”) technology. In 2019 we began incorporating our proprietary PowiGaN™ gallium-nitride transistors in some of our products, enabling a higher level of energy efficiency than ICs with silicon transistors. Since then, we have introduced a variety of new products utilizing GaN technology and developed new generations of our GaN technology capable of supporting voltages as high as 1700 volts. While high-voltage GaN transistors have historically been more costly to produce than comparable silicon transistors, we have achieved cost reductions such that our GaN devices are approaching cost parity with silicon MOSFETs.

We are developing additional products incorporating GaN transistors, which we believe will enable us to address higher-power applications than we address with our current range of products, and further expand our SAM as discussed above. We expect such applications to include power supplies used in data centers delivering artificial intelligence (AI) services, in communications network infrastructure equipment and in onboard-charging circuitry for EVs, among others.

Table of Contents

Additionally, we are developing GaN technologies capable of supporting higher power output than today’s GaN devices, with an aim of developing products to address power-switching modules in EV drivetrains, which currently incorporate SiC and IGBT modules. In July 2024 we acquired the assets of Odyssey Semiconductor, a developer of so-called vertical GaN technology, in an effort to accelerate our development of higher-power GaN devices. We believe the development of such technologies will take several years to complete.

●

Capitalize on efforts to reduce carbon emissions by providing products that contribute to improved energy efficiency and increased use of renewable energy. In its 2019 World Energy Outlook, the International Energy Agency estimated that more than two-thirds of the reduction in carbon-dioxide (“CO2”) emissions needed to achieve the “Sustainable Development Scenario” of the United Nations Sustainable Development Agenda is to come from improved energy efficiency and increased use of renewable energy. Energy savings enabled by our products help our customers comply with regulations that seek to curb energy consumption in support of reducing CO2 emissions. For example: our EcoSmart™ technology drastically reduces the amount of energy consumed by electronic products when they are plugged in but not in use; our PowiGaN™ gallium-nitride (“GaN”) transistors reduce energy consumption compared to silicon transistors; and our BridgeSwitch™ motor-driver ICs provide highly efficient power conversion for BLDC motors in appliances and industrial applications. Also, our gate-driver products are critical components in energy-efficient DC motor drives, solar- and wind-power systems, efficient high-voltage DC transmission systems (including transmission of energy from renewable energy installations to the power grid), and low-emissions transportation applications such as electric locomotives.

We intend to continue expanding our SAM in the years ahead through all of the means described above.

Our quarterly operating results are difficult to predict and subject to significant fluctuations. We plan our production and inventory levels based on internal forecasts of projected customer demand, which are highly unpredictable and can fluctuate substantially. Customers typically may cancel or reschedule orders on short notice without significant penalty and, conversely, often place orders with very short lead times to delivery. Changes in trade policies among the United States and other countries, in particular the escalation of trade tensions and higher tariffs as well as the imposition of other barriers to international trade could reduce demand for end products that incorporate our integrated circuits which could adversely affect our business and operating results. See also our risk factor under Part II, Item 1A captioned, “Changes in trade policies among the United States and other countries, in particular the escalation and imposition of new and higher tariffs, could reduce demand for end products that incorporate our integrated circuits, which could have a material adverse effect on our revenues and operating results. Further, increased tariffs or the imposition of other barriers to international trade could place pressure on our prices as our customers seek to offset the impact of increased tariffs on their own products.” Also, external factors such as supply-chain dynamics, widespread health emergencies, and macroeconomic conditions including inflation, fluctuations in interest and exchange rates and bank failures, have caused and can continue to cause our operating results to be volatile. Furthermore, because our industry is intensely price-sensitive, our gross margin (gross profit divided by net revenues) is subject to change based on the relative pricing of solutions that compete with ours. Variations in product mix, end-market mix and customer mix can also cause our gross margin to fluctuate. Because we purchase a large percentage of our silicon wafers from foundries located in Japan, our gross margin is influenced by fluctuations in the exchange rate between the U.S. dollar and the Japanese yen. Changes in the prices of raw materials used in our products, such as copper and gold, can also affect our gross margin. Although our wafer fabrication and assembly operations are outsourced, as are most of our test operations, a portion of our production costs are fixed in nature. As a result, our unit costs and gross margin are impacted by the volume of units we produce.

Recent Results

Our net revenues were $105.5 million and $91.7 million in the three months ended March 31, 2025 and 2024, respectively. The increase in net revenues was due to higher sales in all four end-market categories, most significantly in the consumer end-market.

Our top ten customers, including distributors that resell to OEMs and merchant power supply manufacturers, accounted for 80% and 77% of net revenues for the three months ended March 31, 2025 and 2024, respectively. International sales accounted for 99% and 98% of our net revenues for the three months ended March 31, 2025 and 2024, respectively.

Table of Contents

Our gross margin was 55% and 52% for the three months ended March 31, 2025 and 2024, respectively. The increase in gross margin was primarily due to the favorable impact of the dollar/yen exchange rate on our wafer costs and the favorable impact of higher manufacturing volumes on our cost per unit.

Total operating expenses were $51.5 million and $47.3 million for the three months ended March 31, 2025 and 2024, respectively. The increase in operating expenses for the three-month period was primarily due to increased stock-based compensation expense and employee-related expenses driven by headcount growth and higher costs associated with employee health insurance and other benefits. These increases were partially offset by a credit recognized in the three months ended March 31, 2025 related to the recovery of bad debt.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those listed below. We base our estimates on historical facts and various other assumptions that we believe to be reasonable at the time the estimates are made. Actual results could differ from those estimates.

Critical accounting policies are important to the portrayal of our financial condition and results of operations and require us to make judgments and estimates about matters that are inherently uncertain. There have been no material changes to our critical accounting policies and estimates disclosed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” and Note 2, Significant Accounting Policies and Recent Accounting Pronouncements, in each case in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 7, 2025. Currently, our only critical accounting policies relate to revenue recognition and estimating write-downs for excess and obsolete inventory.

Comparison of the three months ended March 31, 2025 and 2024

Net revenues. Net revenues consist of revenues from product sales, which are calculated net of returns and allowances. Net revenues for the three months ended March 31, 2024 and 2024 were $105.5 million and $91.7 million, respectively. The increase in net revenues was due to higher sales in all four end-market categories, most significantly in the consumer end-market.

Table of Contents

Our revenue mix by end market for the three months ended March 31, 2025 and 2024 was as follows:


	Three Months Ended
	March 31,
End Market	2025		2024
Communications	10	%	11	%
Computer	12	%	11	%
Consumer	44	%	41	%
Industrial	34	%	37	%

International sales, consisting of sales outside of the United States of America based on “bill to” customer locations, were $104.2 million and $90.1 million in the three months ended March 31, 2025 and 2024, respectively. Although power converters using our products are distributed to end markets worldwide, most are manufactured in Asia. As a result, sales to this region represented 84% and 81% of our net revenues in the three months ended March 31, 2025 and 2024, respectively. We expect international sales, and sales to the Asia region in particular, to continue to account for a large portion of our net revenues in the future.

Sales to distributors accounted for 71% and 72% of our net revenues in the three months ended March 31, 2025 and 2024, respectively, with direct sales to OEMs and merchant power supply manufacturers accounting for the remainder.

The following customers represented 10% or more of our net revenues for the respective periods:

*Total customer revenue was less than 10% of net revenues.

No other customers accounted for 10% or more of our net revenues in these periods.

Gross profit. Gross profit is net revenues less cost of revenues. Our cost of revenues consists primarily of the purchase of wafers from our contracted foundries, the assembly, packaging and testing of our products by sub-contractors, product testing performed in our own facility, overhead associated with the management of our supply chain and the amortization of acquired intangible assets. Gross margin is gross profit divided by net revenues. The following table compares gross profit and gross margin for the three months ended March 31, 2025 and 2024:


	Three Months Ended
	March 31,
(dollars in millions)	2025			2024
Net revenues	$	105.5		$	91.7
Gross profit	$	58.2		$	47.8
Gross margin		55.2	%		52.1	%

Our gross margin increased primarily due to favorable impact of the dollar/yen exchange rate on our wafer costs and the favorable impact of higher manufacturing volumes on our cost per unit.

Research and development expenses. Research and development (“R&D”) expenses consist primarily of employee-related expenses including salaries and stock-based compensation, as well as expensed material and facility costs associated with the development of new processes and products. We also record R&D expenses for prototype wafers related to new products until the products are released to production. The following table compares R&D expenses for the three months ended March 31, 2025 and 2024:


	Three Months Ended
	March 31,
(dollars in millions)	2025		2024
R&D expenses	$	24.1	$	23.2
Headcount (at period end)		294		299

R&D expenses increased for the three months ended March 31, 2025 compared to the corresponding period of 2024 primarily due to higher employee benefit-related expenses and increased equipment-related expenses.

Table of Contents

Sales and marketing expenses. Sales and marketing (“S&M”) expenses consist primarily of employee-related expenses, including salaries and stock-based compensation, and commissions to sales representatives, as well as facilities expenses, including expenses associated with our regional sales and support offices. The following table below compares S&M expenses for the three months ended March 31, 2025 and 2024:


	Three Months Ended
	March 31,
(dollars in millions)	2025		2024
Sales and marketing expenses	$	16.4	$	15.7
Headcount (at period end)		330		322

S&M expenses increased for the three months ended March 31, 2025 compared to the corresponding period of 2024, primarily due to higher sales commissions and increased employee benefit-related expenses.

General and administrative expenses. General and administrative (“G&A”) expenses consist primarily of employee-related expenses, including salaries and stock-based compensation expenses for administration, finance, human resources and general management, as well as consulting, professional services, legal and auditing expenses. The following table below compares G&A expenses for the three months ended March 31, 2025 and 2024:

G&A expenses increased for the three months ended March 31, 2025 compared to the corresponding period of 2024, primarily due to increased stock-based compensation expense related to performance-based awards as well as increased expenses for legal and other professional services. These increases were partially offset by a credit recognized in the three months ended March 31, 2025 related to the recovery of bad debt.

Other income. Other income consists primarily of interest income earned on cash and cash equivalents, marketable securities and other investments, and the impact of foreign exchange gains or losses. The table below compares other income for the three months ended March 31, 2025 and 2024:

Other income for the three months ended March 31, 2025 was similar to the corresponding period of 2024.

Provision for income taxes. Provision for income taxes represents federal, state and foreign taxes. The table below compares income-tax expense for the three months ended March 31, 2025 and 2024:


	Three Months Ended
	March 31,
(dollars in millions)	2025			2024
Provision for income taxes	$	1.1		$	—
Effective tax rate		11.1	%		0.5	%

Income-tax expense includes a provision for federal, state and foreign taxes based on the annual estimated effective tax rate applicable to us and our subsidiaries, adjusted for certain discrete items which are fully recognized in the period in which they occur. Accordingly, the interim effective tax rate may not be reflective of the annual estimated effective tax rate.

Our effective tax rates for the three months ended March 31, 2025 and 2024 was 11.1% and 0.5%, respectively. The effective tax rate in these periods was lower than the statutory federal income-tax rate of 21% due to the geographic distribution of our world-wide earnings in lower-tax jurisdictions and the impact of federal research tax credits. In the three months ended March 31, 2025, our effective tax rate was unfavorably impacted by the recognition of share-based payments and foreign income subject to U.S. tax (GILTI). In the three months ended March 31, 2024, our effective tax

Table of Contents

rate was favorably impacted by the recognition of excess tax benefits related to share-based payments and the release of unrecognized tax benefits and unfavorably impacted by foreign income subject to U.S. tax (GILTI). These benefits were partially offset by U.S. tax on foreign income, known as global intangible low-taxed income. The primary jurisdiction from which our foreign earnings are derived is the Cayman Islands, which is a non-taxing jurisdiction. Income earned in other foreign jurisdictions was not material. We have not been granted any incentivized tax rates and do not operate under any tax holidays in any jurisdiction.

Liquidity and Capital Resources

As of March 31, 2025, we had $289.3 million in cash, cash equivalents and short-term marketable securities, a decrease of $10.7 million from $300.0 million as of December 31, 2024. As of March 31, 2025, we had working capital, defined as current assets less current liabilities, of $444.9 million, a decrease of approximately $13.8 million from $458.7 million as of December 31, 2024.

We have a Credit Agreement with Wells Fargo Bank, National Association (the "Credit Agreement") that provides us with a $75.0 million revolving line of credit to use for general corporate purposes with a $20.0 million sub-limit for the issuance of standby and trade letters of credit. The Credit Agreement was amended on June 7, 2021, to provide an alternate borrowing rate as a replacement for LIBOR and extend the termination date from April 30, 2022, to June 7, 2026, with all other terms remaining the same. The Credit Agreement was amended with an effective date of June 28, 2023 to include the Secured Overnight Financing Rates (“SOFR”) as interest rate benchmark rates, with all other terms remaining the same. Our ability to borrow under the revolving line of credit is conditioned upon our compliance with specified covenants, including reporting and financial covenants, primarily a minimum liquidity measure and a debt to earnings ratio, with which we are currently in compliance. The Credit Agreement terminates on June 7, 2026; all advances under the revolving line of credit will become due on such date, or earlier in the event of a default. As of March 31, 2025, we had no advances outstanding under the Credit Agreement.

Cash from Operating Activities

Our operating activities generated $26.4 million of cash in the three months ended March 31, 2025. Net income for this period was $8.8 million; we also incurred non-cash stock-based compensation expense, depreciation and an increase in deferred tax assets of $8.7 million, $7.2 million and $2.5 million, respectively. Sources of cash included a $4.7 million decrease in accounts receivable due to timing of receipts, an increase of $4.0 million in accounts payable (excluding payables related to property and equipment) due to timing of payments and a $3.4 million decrease in prepaid expenses and other assets. These sources of cash were partially offset by a $3.9 million decrease in taxes payable and accrued liabilities and a $3.5 million increase in inventories.

Operating activities generated $15.9 million of cash in the three months ended March 31, 2024. Net income for this period was $4.0 million; we also incurred depreciation, non-cash stock-based compensation expense, increase in deferred tax assets, accretion of discount on marketable securities, and amortization of intangibles of $8.7 million, $6.4 million, $1.3 million, $0.5 million and $0.5 million, respectively. Sources of cash included a $2.2 million decrease in accounts receivable due to timing of receipts, a $1.3 million increase in accounts payable (excluding payables related to property and equipment) due to timing of payments and a $0.8 million decrease in prepaid expenses and other assets. These sources of cash were partially offset by a $4.7 million increase in inventories due to lower demand during the quarter and a $1.7 million decrease in taxes payable and accrued liabilities.

Cash from Investing Activities

Our investing activities in the three months ended March 31, 2025, generated $4.5 million of cash, primarily consisting of $10.3 million from sales and maturities of marketable securities, net of purchases, offset by $5.7 million for purchases of property and equipment (primarily production-related machinery and equipment).

Our investing activities in the three months ended March 31, 2024 resulted in $0.1 million net use of cash, primarily consisting of $4.3 million used for purchases of property and equipment (primarily production-related machinery and equipment), partially offset by $4.3 million from sales and maturities of marketable securities, net of purchases.

Table of Contents

Cash from Financing Activities

Our financing activities in the three months ended March 31, 2025 resulted in a $32.3 million net use of cash, consisting of $23.1 million for the repurchase of our common stock and $12.0 million for the payment of dividends to stockholders, partially offset by proceeds of $2.8 million from the issuance of shares through our employee stock purchase plan.

Our financing activities in the three months ended March 31, 2024 resulted in a $23.3 million net use of cash, consisting of $14.6 million for the repurchase of our common stock and $11.4 million for the payment of dividends to stockholders, partially offset by proceeds of $2.7 million from the issuance of shares through our employee stock purchase plan.

Dividends

In October 2023, our board of directors declared dividends of $0.20 per share to be paid to stockholders of record at the end of each quarter in 2024.

In October 2024, our board of directors raised the cash dividend with the declaration of five cash dividends of $0.21 per share to be paid at the end of the fourth quarter in 2024 (in lieu of the previously declared dividend of $0.20 per share announced in October 2023) and at the end of each quarter in 2025. A dividend payout of $12.0 million occurred on March 31, 2025.

The declaration of any future cash dividend is at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that cash dividends are in the best interest of our stockholders.

Stock Repurchases

Over the years, our board of directors have authorized the use of funds to repurchase shares of our common stock. As of December 31, 2024, we had $48.1 million remaining under our stock-repurchase program. In the three months ended March 31, 2025, we repurchased approximately 404,000 shares for $23.1 million, leaving $25.0 million in funds authorized as of March 31, 2025. In April 2025, we utilized the remaining $25.0 million, repurchasing approximately 560,000 shares of our common stock. Subsequently, our board of directors authorized the use of an additional $50.0 million for the repurchase of our common stock, with repurchases to be executed according to pre-defined price/volume guidelines. The program has no expiration date. Authorization of future repurchase programs is at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements, business conditions and other factors.

Contractual Commitments

As of March 31, 2025, there were no material changes in our contractual commitments from those reported in our Annual Report on Form 10-K for the year ended December 31, 2024.

Other Information

Our cash, cash equivalents and investment balances may change in future periods due to changes in our planned cash outlays, including changes in incremental costs such as direct and integration costs related to future acquisitions. Current U.S. tax laws generally allow companies to repatriate accumulated foreign earnings without incurring additional U.S. federal taxes. Accordingly, as of March 31, 2025, our worldwide cash and marketable securities are available to fund capital allocation needs, including capital and internal investments, acquisitions, stock repurchases and/or dividends without incurring significant U.S. federal income taxes.

If our operating results deteriorate in future periods, either as a result of a decrease in customer demand or pricing pressures from our customers or our competitors, or for other reasons, our ability to generate positive cash flow from operations may be jeopardized. In that case, we may be forced to use our cash, cash equivalents and short-term investments, use our current financing or seek additional financing from third parties to fund our operations. We believe that cash generated from operations, together with existing sources of liquidity, will satisfy our projected working capital and other cash requirements for at least the next 12 months. Our uses of cash beyond the next 12 months will depend on many factors, including the general economic environment in which we operate and our ability to generate cash flow from operations, which are uncertain but include funding our operations and additional capital expenditures.

ITEM 4. CONTROLS AND PROCEDURES

Limitation on Effectiveness of Controls

Any control system, no matter how well designed and operated, can provide only reasonable assurance as to the tested objectives. The design of any control system is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. The inherent limitations in any control system include the realities that judgments related to decision-making can be faulty, and that reduced effectiveness in controls can occur because of simple errors or mistakes. Due to the inherent limitations in a cost-effective control system, misstatements due to error may occur and may not be detected.

Evaluation of Disclosure Controls and Procedures

Management is required to evaluate our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Disclosure controls and procedures are controls and other procedures designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include controls and procedures designed to provide reasonable assurance 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. Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of the end of the period covered by this report.

ITEM 1A. RISK FACTORS

Except as discussed below, there have been no material changes to the risks described in Part I Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2024, which risk factors are incorporated herein by reference in this report from Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 7, 2025.

Risks Related to the Operation and Growth of Our Business

Changes in trade policies among the United States and other countries, in particular the escalation and imposition of new and higher tariffs, could reduce demand for end products that incorporate our integrated circuits, which could have a material adverse effect on our revenues and operating results. Further, increased tariffs or the imposition of other barriers to international trade could place pressure on our prices as our customers seek to offset the impact of increased tariffs on their own products.

Although power supplies using our products are designed and distributed worldwide, most of these power supplies are manufactured by our customers in Asia. As a result, our business is subject to risks related to tariffs and other trade protection measures put in place by the United States or other countries, as well as U.S. international trade relations, including but not limited to those with China, countries in the APAC region and the European Union.

In the first quarter of 2025, the United States government announced additional tariffs on goods imported into the U.S. from numerous countries, and multiple countries countered with reciprocal tariffs and other actions in response. Changes in trade policies and a heightened risk of further increased tariffs or other barriers to international trade could further decrease international demand. Many of our customers sell products incorporating our integrated circuits into international markets.

Existing or future tariffs proposed or imposed on our customers’ products may adversely affect our gross profit margins in the future due to the potential for increased pressure on our selling prices by customers seeking to offset the impact of tariffs on their own products. In addition, tariffs could make our customers’ products less attractive relative to products offered by their competitors, which may not be subject to similar tariffs. Further increases in tariffs on imported goods or the failure to resolve current international trade disputes could further decrease demand and have a material adverse effect on our business and operating results.

Resulting trade disputes, trade restrictions, tariffs and other political tensions between the U.S. and other countries may also exacerbate unfavorable macroeconomic conditions including inflationary pressures, foreign exchange volatility, financial market instability, and economic recessions or downturns, which may also negatively impact customer demand for our products or services, delay purchases or renewals, limit expansion opportunities with customers, limit our access to capital, or otherwise negatively affect our business and operations. Ongoing tariff, trade restrictions and macroeconomic uncertainty also has and may continue to contribute to volatility in the price of our common stock.

Furthermore, compliance with export controls and implementation of additional tariffs may increase compliance costs and further affect our business and operating results.

In the event the Executive is not eligible for Medicare coverage at the end of his maximum applicable COBRA coverage period, then, the Executive shall identify and locate either or both an individual conversion policy through the insurer providing insurance coverage in connection with the Company sponsored medical and dental plans available to active employees (the “Conversion Policy”), and/or a supplemental individual policy or an individual policy on the open market (the “Individual Policy”) to be effective upon the termination of his COBRA continuation coverage so that, when the coverages for Executive provided by the Conversion Policy and/or the Individual Policy are combined, such coverages provide substantially similar medical and dental benefits in the aggregate as those provided under the medical and dental plans sponsored by the Company at such time, or at any time after the termination of Executive’s employment, for active employees (the “Comparable Coverage”). The Company shall be responsible for the payment of any Conversion Policy premiums and/or Individual Policy premiums for the Comparable Coverage which payment shall not exceed the cost of premiums for medical and dental coverage for then active employees. If Executive is at such time eligible to participate under the Company Plans, Executive will be entitled to so participate.

(C)Coverage After COBRA & Upon Medicare Eligibility. In the event the Executive is eligible for Medicare coverage at the end of his maximum applicable COBRA coverage period, the Executive may identify and locate a Medicare supplemental policy, which may include, to the extent permitted, the medical and dental plans sponsored by the Company at such time for active employees (the “Company Plans”), that, when combined with the coverage provided by Medicare, provides Comparable Coverage. If Executive is at such time eligible to participate under the Company Plans, Executive will be entitled to so participate; provided that Executive shall be solely responsible for the payment of any Medicare premiums and/or Medical supplemental policy premiums for the Comparable Coverage (including, if applicable, any premiums under the Company Plans).

(D)Taxes, Coverage. The Executive shall be responsible for any taxes that may be attributable to or result from the payments made by the Company in accordance with this Section 5(b)(iii) or receipt of medical and dental benefits attributable to or result from such payments. Notwithstanding Section 5(b)(iii)(A) or (B), in the event Executive becomes eligible to be covered under another employer’s group health plan (other than a plan which imposes a preexisting condition exclusion to the extent permissible by law, unless the preexisting condition exclusion does not apply) during the period provided for herein, the Company shall cease payment of any premiums. The Company will use commercially reasonable efforts to provide that Executive will continue to be eligible for coverage as provided under this Section 5(b)(iii) under the Company Plans, unless the Board of Directors or Compensation Committee determines that such coverage would create an undue burden on the Company.

6.Termination of Employment due to Death or Permanent Disability.

(a)In the event of (i) the Executive’s death during his employment with the Company and the Executive having satisfied the criteria provided at Section 5(a)(i) as of or prior to the date of his death or (ii) the Executive’s death during the period while Executive was receiving Retirement Benefits as a result of compliance with the criteria provided at Section 5(a)(i) and 5(a)(ii), (1) the Executive’s legal representative or any person empowered to act on his behalf under his will or under the then applicable laws of descent and distribution shall be entitled to the benefits pursuant to Section 5(b)(i) (“Option Exercisability”) and Section 5(b)(ii) (“Performance Stock Awards”) and (2) the Executive’s dependents, to the extent applicable, shall be entitled to the benefits pursuant to Section 5(b)(iii)(A)-(D) (“Medical and Dental Coverage”) for that period of time until the Executive would have achieved the age of Medicare eligibility if the Executive had lived.

(b)In the event of the Executive’s Permanent Disability during his employment with the Company and the Executive having satisfied the criteria provided at Section 5(a)(i), the Executive, and to the extent applicable, his dependents, shall be entitled to the benefits provided in Section 5(b)(i) (“Option Exercisability”), Section 5(b)(ii) (“Performance Stock Awards”) and 5(b)(iii)(A)-(D) (“Medical and Dental Coverage”).

7.Payment of Taxes. All payments made to Executive under this Agreement shall be subject to all applicable federal and state income, employment and payroll taxes, including all withholding taxes.

8.Parachute Payment. Executive is strongly encouraged to review the following provision and consult with his or her tax and financial advisor concerning the application of any personal tax consequences related to any payments provided for under this Agreement and the following provision. In the event that any of the payments and benefits provided for in this Agreement or otherwise payable to the Executive (a “280G Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then any such 280G Payment pursuant to this Agreement (a “Payment”) shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (i) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (ii) the largest portion, up to and including the total, of the Payment, whichever amount (i.e., the amount determined by clause (i) or by clause (ii)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in the receipt by Executive, on an after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in a Payment is required pursuant to the preceding sentence and the Reduced Amount is determined pursuant to clause (x) of the preceding sentence, the reduction shall occur in the manner (the “Reduction Method”) that results in the greatest economic benefit for Executive. If more than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata (the “Pro Rata Reduction Method”). Notwithstanding the foregoing, if the Reduction Method or the Pro Rata Reduction Method would result in any portion of the Payment being subject to taxes pursuant to Section 409A that would not otherwise be subject to taxes pursuant to Section 409A, then the Reduction Method and/or the Pro Rata Reduction Method, as the case may be, shall be modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (A) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for Executive as determined on an after-tax basis; (B) as a second priority, Payments that are contingent on future events (e.g., being terminated without cause), shall be reduced (or eliminated) before Payments that are not contingent on future events; and (C) as a third priority, Payments that are “deferred compensation” within the meaning of Section 409A shall be reduced (or eliminated) before Payments that are not deferred compensation within the meaning of Section 409A. Unless the Company and the Executive otherwise agree in writing, any determination required under this Section 8 shall be made in writing by independent public accountants appointed by the Company and reasonably acceptable to the Executive (the “Accountants”), whose determination shall be conclusive and binding upon the Executive and the Company for all purposes. The Company shall bear all costs the Accountants may reasonably incur in connection with such determination, and the Company and the Executive shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 8.

9.Exclusive Remedy. The payments and benefits provided for in Section 3, Section 4, Section 5 or Section 15 shall constitute the Executive’s sole and exclusive remedy for any alleged injury or other damages arising out of the cessation of the employment relationship between the Executive and the Company. The parties hereto agree that irreparable damage would occur if any of the provisions of this Agreement were not performed in accordance with these specific terms or were otherwise breached. It is

accordingly agreed that the parties shall be entitled to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at law or in equity.

10.Proprietary and Confidential Information. The Executive agrees to continue to abide by the terms and conditions of any Company’s confidentiality and/or proprietary rights agreement between the Executive and the Company.

11.Arbitration. Any claim, dispute or controversy arising out of this Agreement, the interpretation, validity or enforceability of this Agreement or the alleged breach thereof shall be submitted by the parties to binding arbitration by the American Arbitration Association in San Jose, California or elsewhere by mutual agreement. The selection of the arbitrator and the arbitration procedure shall be governed by the Commercial Arbitration Rules of the American Arbitration Association. All costs and expenses of arbitration or litigation, including but not limited to reasonable attorneys fees and other costs reasonably incurred by the Executive, shall be paid by the Company. Judgment may be entered on the award of the arbitration in any court having jurisdiction.

12.Interpretation. Executive and the Company agree that this Agreement shall be interpreted in accordance with and governed by the laws of the State of California, without regard to such state’s conflict of laws rules.

13.Conflict in Benefits. This Agreement shall supersede all prior arrangements, whether written or oral, and understandings regarding the subject matter of this Agreement. To the extent Executive is entitled to severance or other benefits upon termination of employment under this Agreement and any other agreement, including any change in control agreement entered into by the Company and the Executive, entered into prior to the Effective Date, the benefits payable under this Agreement shall supersede and replace any other such agreement. However, this Agreement is not intended to and shall not affect, limit or terminate (i) any plans, programs, or arrangements of the Company that are regularly made available to a significant number of employees of the Company, (ii) the Company’s equity incentive plans, (iii) any agreement or arrangement with the Executive that has been reduced to writing and which does not relate to the subject matter hereof, or (iv) any agreements or arrangements hereafter entered into by the parties in writing, except as otherwise expressly provided herein.

14.Release of Claims. Executive shall receive the severance benefits or the Retirement Benefits pursuant to this Agreement only if Executive executes and returns to the Company, within the applicable time period set forth therein but in no event more than sixty (60) days following the date of Executive’s Separation from Service, a release of claims (the “Release of Claims”) in favor of the Company in a form reasonably satisfactory to the Company, and permits such Release of Claims to become effective in accordance with its terms on or prior to such sixtieth day (the “Release Agreement Deadline”). If the Release of Claims does not become effective by the Release Agreement Deadline, the Executive will forfeit any right to severance benefits or Retirement Benefits pursuant to this Agreement. Regardless of whether the Release of Claims becomes effective prior to the Release Agreement Deadline, any severance benefits or Retirement Benefits payable prior to the Release Agreement Deadline shall be paid on the Release Agreement Deadline, with the remainder of the payments to be made as originally scheduled. Except to the minimum extent that payments must be delayed pursuant to Section 20(c) because Executive is a “specified employee” or until the effectiveness (or deemed effectiveness) of the Release of Claims, all amounts will be paid as soon as practicable in accordance with the Company’s normal payroll practices following Executive’s Separation from Service. Notwithstanding the foregoing, the Release of Claims shall not be construed to waive any right to indemnification or contribution otherwise available to Executive under law or rules of corporate governance with respect to claims by third parties for actions or omissions in Executive’s role as an officer of the Company.

15.Successors and Assigns.

(a)Successors of the Company. The Company will require any successor or assign (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, expressly, absolutely and unconditionally to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession or assignment had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of any such succession transaction shall be a breach of this Agreement and shall entitle the Executive to terminate his or her employment with the Company within three (3) months thereafter and to receive the benefits provided under Section 3 of this Agreement in the event of a Termination Upon Change of Control; provided, however, that (i) such termination of employment must be a Separation from Service and (ii) the Executive must deliver a Release of Claims as provided in Section 14. As used in this Agreement, “Company” shall mean the Company as defined above and any successor or assign to its business and/or assets as aforesaid which executes and delivers the agreement provided for in this Section 15 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

(b)Heirs of Executive. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal and legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

16.Notices. For purposes of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States registered mail, return receipt requested, postage prepaid, as follows:

if to the Company:

Power Integrations, Inc.
5245 Hellyer Avenue
San Jose, California 95138
Attn: Chief Executive Officer or Chief Financial Officer

and if to the Executive, at the address specified in this Agreement. Notice may also be given at such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

17.No Representations. Executive acknowledges that he/she is not relying and has not relied on any promise, representation or statement made by or on behalf of the Company which is not set forth in this Agreement.

18.Validity. If any one or more of the provisions (or any part thereof) of this Agreement shall be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions (or any part thereof) shall not in any way be affected or impaired thereby.

19.Consultation with Legal and Financial Advisors. Executive acknowledges that his Agreement confers significant legal rights, and may also involve the waiver of rights under other agreements; that the Company has encouraged Executive to consult with Executive’s personal legal and financial advisers; and that Executive has had adequate time to consult with Executive’s advisers before signing this Agreement.

20.Application of Section 409A and Other Limitations. Executive is strongly encouraged to review the following provisions and consult with his or her tax and financial advisor concerning the

application of any personal tax consequences related to any payments provided for under this Agreement and the following provisions.

(a)If any Stock Award (other than stock options) vesting pursuant to Section 2(a), Section 2(b), Section 3(a)(v)(2) or Section 4(b)(ii):

(i)does not constitute “deferred compensation” within the meaning of Section 409A, the shares vesting pursuant to such events will be issued (1) in respect of Section 2(a), Section 2(b) and Section 4(b)(ii) immediately prior to the consummation of the Change of Control, and (2) in respect of Section 3(a)(v)(2) on the sixtieth (60^th) day following the Termination Upon Change of Control as further provided in Section 14 hereof.

(ii)does constitute “deferred compensation” within the meaning of Section 409A, the shares vesting pursuant to such events will be issued (1) in respect of Section 2(a), Section 2(b) and Section 4(b)(ii) immediately prior to the Change of Control, provided such payment can be made without adverse personal tax consequences to the Executive, or else the shares vesting pursuant to Section 2(a), Section 2(b) and Section 4(b)(ii) will be converted into the same consideration received by the holders of the Company’s common stock pursuant to the Change of Control, and such consideration will be issued in accordance with the delivery schedule for such Stock Award in effect immediately prior to the Change of Control and (2) in respect of Section 3(a)(v)(2) will be issued in accordance with the delivery schedule for such Stock Award in effect immediately prior to the Termination Upon Change of Control.

(b)Extension of Stock Option Exercise Period. Notwithstanding anything to the contrary in this Agreement, in the event any extended exercise period provided for in this Agreement shall result in a portion of a stock option becoming subject to the provisions of Section 409A, the extended exercise period of such portion of such stock option shall be automatically shortened by the minimum extent necessary to prevent such portion of such option from becoming subject to Section 409A. In no event will any provisions in this Agreement providing for an extended exercise period result in the extension of the exercise period of any stock option beyond the maximum permitted term of such stock option as provided under the applicable equity incentive plan and stock option award agreement in effect for such stock option, assuming for the purposes of this Section 20(b) no termination of Executive’s employment with the Company.

(c)Other Benefits. Notwithstanding anything to the contrary herein, the following provisions apply to the extent any benefits (“Benefits”) provided herein other than those described in Section 20(b) are subject to Section 409A: (A) The Benefits are intended to qualify for an exemption from application of Section 409A or comply with the requirements of Section 409A to the extent necessary to avoid adverse personal tax consequences under Section 409A, and any ambiguities herein shall be interpreted accordingly. (B) Benefits contingent on a termination of employment shall not commence until Executive has a Separation from Service. (C) Each installment of a Benefit is a separate “payment” for purposes of Treas. Reg. Section 1.409A-2(b)(2)(i). (D) Each Benefit is intended to satisfy the exemptions from application of Section 409A provided under Treasury Regulations Sections 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9) to the maximum extent available. However, if such exemptions are not available and Executive is, upon Executive’s Separation from Service, a “specified employee” for the purposes of Section 409A, then, solely to the extent necessary to avoid adverse personal tax consequences under Section 409A, the timing of the Benefit payments otherwise payable prior to such date shall be delayed until the earlier of (x) six (6) months and one day after Executive’s Separation from Service, or (y) Executive’s death, and any payments otherwise scheduled to be made after such date shall be paid as originally scheduled. (E) To the extent that any reimbursements payable to Executive pursuant to Section 3(a)(iii) are subject to the provisions of Section 409A, the following provisions will apply in addition to the provisions of any applicable expense reimbursement policy: (a) to be eligible to obtain reimbursement for such expenses

Executive must submit expense reports within 45 days after the expense is incurred, (b) any such reimbursements will be paid no later than the earlier of (x) thirty (30) days after the date Executive submits receipts for the expenses or (y) December 31 of the year following the year in which the expense was incurred, (c) the amount of expenses reimbursed in one year will not affect the amount eligible for reimbursement in any subsequent year, and (d) the right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit.

(d)Payment of Health Care Benefits. Notwithstanding anything to the contrary set forth herein, if the Company determines, in its sole discretion, that it cannot provide the COBRA premium, Conversion Policy premium, Individual Policy premium, or other medical and dental coverage premiums (together the “Health Care Benefits”) contemplated under this Agreement without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof pay Executive a taxable cash amount, which payment shall be made regardless of whether Executive or Executive’s eligible family members elect health care continuation coverage (the “Health Care Benefit Payment”). Subject to any further delay in payment required by Section 14 of this Agreement, the Health Care Benefit Payment shall be paid in monthly installments on the same schedule that such amounts would otherwise have been paid to the insurer. The Health Care Benefit Payment shall be equal to (a) the amount that the Company would have otherwise paid to provide the Health Care Benefits for the duration of the applicable severance period (which amount shall be calculated based on the premium for the first month of coverage), plus (b) an additional amount such that after payment of all taxes, Executive retains an amount equal to the Company’s aggregate cost of otherwise providing the Health Care Benefits. For purposes of calculating the “additional amount” in clause (b) of the preceding sentence, Executive shall be deemed to have: paid federal income taxes at the highest marginal rate of federal income and employment taxation for the calendar year in which the Health Care Benefit Payment is to be made, and paid applicable state and local income taxes at the highest rate of taxation for the calendar year in which the Health Care Benefit Payment is to be made, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes.
