Current report

Our net revenues were $106.2 million and $123.2 million in the three months ended June 30, 2024 and 2023, respectively, and $197.9 million and $229.5 million in the six months ended June 30, 2024 and 2023, respectively. The decrease in net revenues for the three-month period was driven primarily by the communications end-market, reflecting lower sales of our products for use in smartphone chargers. This was driven by a variety of factors including excess inventories at certain end-customers, shifts in market share among handset vendors, diversification of component suppliers among Chinese handset original equipment manufacturers (“OEMs”), including greater use of Chinese-made components, and increased decoupling of handsets and chargers. Lower sales into the computer market also contributed to the decline, due primarily to excess inventory related to chargers for tablet computers. These decreases were partially offset by higher sales into the consumer end-market, reflecting depletion of excess inventories related to the appliance market. For the six-month period ended June 30, 2024, revenues for all but the consumer end-market category decreased compared to the corresponding prior-year period.

Current report

Total operating expenses were $54.6 million and $50.2 million for the three months ended June 30, 2024 and 2023, respectively, and $101.9 million and $98.4 million for the six months ended June 30, 2024 and 2023, respectively. The increase in operating expenses for the three- and six-month periods was primarily due to higher stock-based compensation expense related to performance-based awards and higher salaries and related expenses driven byexpansion of headcount and annual merit increases. Partially offsetting these increases were decreased product-development expenses. In addition, we recognized a credit to expenses in the first six months of 2023 related to the recovery of bad debt.

Previous wording

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.

Current wording

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.

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.

Current wording

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 wording

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. In 2019 we began incorporating our proprietary GaN 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, as well as new generations of our GaN technology capable of supporting higher voltages (as high as 1250 volts). We are currently developing new products incorporating these technologies, which we believe will enable us to address higher-power applications than we address with our current range of products and therefore further expand our SAM.

Previous wording

Our net revenues were $91.7 million and $106.3 million in the three months ended March 31, 2024 and 2023, respectively. We believe that demand for our products has been negatively affected by an array of macroeconomic and geopolitical factors including reduced consumer spending and a reduction in home sales in response to inflation and higher interest rates, general economic weakness in China, weaker industrial activity and the conflicts in Ukraine and the Middle East. We believe these factors have exacerbated the effects of an ongoing cyclical downturn in the semiconductor industry; such downturns are commonly experienced following periods of strong growth during which supply-chain participants tend to accumulate excess inventories. Also contributing to the decrease in revenues has been a reduction in sales of our products for mobile-phone chargers; this reflects a variety of factors including increased decoupling of smartphone handsets and chargers, shifts in market share among handset vendors and diversification of component suppliers among Chinese handset OEMs, including greater use of Chinese-made components.

Current wording

In general, we believe that demand for our products has been negatively affected in recent periods by an array of macroeconomic and geopolitical factors including reduced consumer spending and a reduction in home sales in response to inflation and higher interest rates, general economic weakness in China, weaker industrial activity and the conflicts in Ukraine and the Middle East. We believe these factors have exacerbated the effects of a cyclical downturn in the semiconductor industry; such downturns are commonly experienced following periods of strong growth during which supply-chain participants tend to accumulate excess inventories. However, inventories at distributors of our products have decreased significantly over the past several quarters, which contributed to an increase in net revenues for the three months ended June 30, 2024 compared to the prior quarter.

Our products bring a number of important benefits to the power-conversion market compared with less advanced alternatives, including reduced component count and design complexity, smaller size, higher reliability and reduced time-to-market. 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 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 heatsinks used to dissipate the heat produced by wasted electricity.

We believe that demand for our products has been negatively affected by an array of macroeconomic and geopolitical factors including reduced consumer spending and a reduction in home sales in response to inflation and higher interest rates, general economic weakness in China, weaker industrial activity and the conflicts in Ukraine and the Middle East. We believe these factors have exacerbated the effects of an ongoing cyclical downturn in the semiconductor industry; such downturns are commonly experienced following periods of strong growth during which supply-chain participants tend to accumulate excess inventories. Also contributing to the decrease in revenues has been a reduction in sales of our products for mobile-phone chargers; this reflects a variety of factors including increased decoupling of smartphone handsets and chargers, shifts in market share among handset vendors, and diversification of component suppliers among Chinese handset OEMs, including greater use of Chinese-made components. As a result of these factors, revenues from our communications category were lower in the three months ended March 31, 2024, as compared to the corresponding
