Current report

Our gross margin was 53% for the three months ended March 31, 2026 and 55% in the corresponding period in 2025. The decrease in gross margin was primarily due to the unfavorable impact of the dollar/yen exchange rate and restructuring related costs.

Current report

Total operating expenses were $55.5 million and $51.5 million for the three months ended March 31, 2026 and 2025, respectively. The increase in operating expenses for the three-month period was primarily due to restructuring and related charges of $6.6 million for severance and benefit costs associated with the workforce reduction described in Note 4 of this report herein. These increases were offset in the three months ended March 31, 2026, by a $1.4 million credit in other operating expenses related to stock-based compensation expense associated with the changes in performance criteria measurement as described in Note 7 of this report herein.

Current report

Our management team continuously evaluates operations to better align our organization with market opportunities, increase operational efficiency, decrease costs and increase profitability. In connection with this, a restructuring plan was undertaken in the first quarter of 2026, reducing the Company’s workforce by approximately 7% to better align our expenses with revenue and create flexibility to invest in the products, people, and markets that are expected to drive long-term growth and profitability. As a result, we recognized restructuring charges of $6.6 million

Current report

In 2016, we entered into the Prior Credit Agreement with Wells Fargo Bank, National Association, which provided us with a $75.0 million revolving line of credit to use for general corporate purposes and a $20.0 million sub-limit for the issuance of standby and trade letters of credit with an interest rate based on SOFR. The Prior Credit Agreement had a term which originally extended to June 7, 2026; the Prior Credit Agreement was terminated on April 10, 2026. We were compliant with all covenants and had no advances outstanding under the Prior Credit Agreement as of termination of the Prior Credit Agreement.

Current report

On February 24, 2026, we entered into the PNC Loan Agreement to replace the Prior Credit Agreement, which became effective and available for use on April 10, 2026 when we terminated the Prior Credit Agreement. The PNC Loan Agreement provides us with a $100.0 million revolving line of credit with a $25.0 million sub-limit for the issuance of standby and trade letters of credit. The interest rate on outstanding borrowings under the PNC Loan Agreement is based on SOFR plus 1.60%. The Company’s obligations under the PNC Loan Agreement are unsecured. The PNC Loan Agreement term extends through February 24, 2031; all advances under the revolving line of credit, together with all accrued and unpaid interest, fees and other obligations owing thereon, will become due on such date, or earlier upon the occurrence of an Event of Default.

Current report

The PNC Loan Agreement requires us to maintain a Minimum Liquidity of at least $50.0 million as of the last day of each fiscal quarter and a ratio of Funded Indebtedness to Adjusted EBITDA of less than 2.00 to 1.00 as of the last day of each fiscal quarter and determined on a rolling four-quarter basis.

Removed paragraphs (37)

Previous report

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.

Previous report

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.

Previous report

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.

Previous report

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.

Previous report

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.

Previous report

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:

Previous report

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.

Previous report

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.

Previous report

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.

Previous report

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.

Previous report

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

Previous report

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 and additional export controls, 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. Compliance with import and export controls could impair our ability to compete in international markets or subject us to liability if we violate these controls.” 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.

Previous report

Our gross margin was 55% for both the three months ended September 30, 2025 and the corresponding period in 2024. Our gross margin was 55% and 53% for the nine months ended September 30, 2025 and 2024, respectively. The increase in gross margin for the nine-month period was primarily due to favorable end-market mix—reflecting a greater amount of revenues coming from higher-margin end-markets.

Previous report

Total operating expenses were $68.8 million and $51.6 million for the three months ended September 30, 2025 and 2024, respectively, and $185.6 million and $153.5 million for the nine months ended September 30, 2025 and 2024, respectively. The increases in operating expenses for the three- and nine-month periods were primarily due to higher stock-based compensation expense as a result of an award modification associated with the retirement of our former chief executive officer (refer to Note 6,Stock-Based Compensation, in our Notes to Unaudited Condensed Consolidated Financial Statements for details) as well as higher expenses for outside engineering services and legal services.

Previous report

Additionally, for the three- and nine-month period, we incurred expenses related to an employee litigation matter (refer to Note 13,Legal Proceedings and Contingencies, in our Notes to Unaudited Condensed Consolidated Financial Statements for details).

Previous report

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

Previous report

The increase in gross margin in the nine-month period was primarily due to favorable end-market mix—reflecting a greater amount of revenues coming from higher-margin end-markets.

Previous report

R&D expenses increased for the three and nine months ended September 30, 2025 as compared to the corresponding periods of 2024. The increases for the three- and nine-month periods were primarily due to higher salaries and related expenses as well as increased outside engineering services. The increase for the nine-month period was partially offsetby lower stock-based compensation expense.

Previous report

*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 and nine months ended September 30, 2025 and 2024:

Previous report

S&M expenses increased forthe three and nine months ended September 30, 2025 as compared to the corresponding periods of 2024. The increases for the three- and nine-month periods were primarily due to increased employee-related expenses. The increase for the nine-month period was partially offset by lower stock-based compensation expense.

Previous report

G&A expenses increased for the three and nine months ended September 30, 2025 as compared to the corresponding periods of 2024. The increase for the three-month period was primarily due to increased professional and legal services partially offset by lower stock-based compensation expense. In addition, we recognized a credit in the three months ended September 30, 2024 related to the recovery of bad debt. The increase for the nine-month period was primarily due to increased professional and legal services and higher stock-based compensation expense related to performance-based awards.

Previous report

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes provisions modifying the corporate income tax code, including the immediate expensing of domestic research and development expenditures for tax purposes, 100% bonus depreciation for qualified assets, and an increase in the statutory tax rate on foreign earnings from 10.5% to 12.6% (effective in the fiscal year 2026). We have elected to account NCTI, formerly known as Global Intangible Low-Taxed Income, under the deferred method. The deferred tax amounts recorded are based on the evaluation of temporary differences that are expected to reverse as NCTI is incurred in future periods. As a result, we remeasured our estimated deferred tax balances related to NCTI for the changes in the tax rate and recorded an expense of $0.5 million during the third quarter of 2025.

Previous report

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 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 September 30, 2025, we had no advances outstanding under the Credit Agreement.

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.

Previous report

Over the years, our board of directors has authorized the use of funds to repurchase shares of our common stock. As of December 31, 2024, we had $48.1 million available under a stock-repurchase program announced in November 2024. After this authorization was exhausted in April 2025, 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 in compliance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. In the three months ended September 30, 2025, we repurchased 0.9 million of our shares for $42.4 million. In the nine months ended September 30, 2025, we repurchased 2.0 million of our shares for $98.1 million, exhausting our repurchase authorization. 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.

Our effective tax rates for the three and nine months ended September 30, 2025, was (3.0%) and 10.5%, respectively, and in the corresponding periods of 2024 was 0.3% and 1.5%, 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 tax credits. In the three and nine months ended September 30, 2025, our effective tax rate was negatively impacted by the recognition of a tax deficiency or “shortfall” related to share-based payments. Additionally, in the three and nine months ended September 30, 2024, our effective tax rate was favorably impacted by the recognition of excess tax benefits related to share-based payments andby discrete items associated with the release of unrecognized tax benefits. These benefits were partially offset by U.S. tax on foreign income, known as Net Controlled Foreign Corporation Tested Income (“NCTI”). 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.

Current wording

Our effective tax rate for the three months ended March 31, 2026, was 15.8%, and 11.1% in the corresponding period of 2025.

In the three months ended March 31, 2026, our effective tax rate was affected by the recognition of a tax accounting shortfall associated with share-based payments. Additionally, 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. We have not been granted any incentivized tax rates and do not operate under any tax holidays in any jurisdiction.

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.

Previous wording

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.
