Performance Analysis

Power Integrations delivered a 9% year-over-year revenue increase to $116 million, with sequential growth of 10% led by the industrial segment. Industrial now represents 40% of total sales, up from historical levels, as metering, automation, and high-power applications drove strength. Notably, metering revenues are on track for 20%+ annual growth, with wins in Japan and Europe leveraging higher ASP, or average selling price, GaN-based products. High-power revenues grew over 40% in the first half, fueled by clean energy and EV traction inverter wins.

Consumer sales, 37% of revenue, declined sequentially after a tariff-fueled Q1 pull-in, with major appliances facing a sharp slowdown as customers front-loaded inventory ahead of tariff implementation. Communication and computer segments saw seasonal upticks, but the overall mix shifted away from lower-margin legacy consumer toward higher-value industrial and automotive. Gross margin held steady at 55.8% despite higher input costs, while operating expenses rose due to executive transition, R&D, and litigation. Cash from operations was $29 million, supporting over $44 million in capital return via buybacks and dividends. Channel and balance sheet inventory remain healthy, positioning POWI for reacceleration post-correction.

  • Industrial Outperformance: Segment grew nearly 30% sequentially, now at a record 40% of sales, with metering and high-power as key drivers.
  • GaN Revenue Surge: GaN-based product revenue rose over 50% in H1, outpacing core business and enabling entry into data center and automotive.
  • Consumer Pullback: Appliance sales fell after Q1 front-running of tariffs, with major appliances down despite offsetting design wins in gaming.

POWI’s business mix is shifting structurally toward higher-margin, higher-growth end markets, even as near-term volatility from tariffs and inventory cycles weighs on the consumer segment.

Executive Commentary

"The core of our business, almost 90% of sales, is power conversion ICs for appliances, consumer electronics, and a wide array of industrial applications. We have a market-leading portfolio of products for these markets with more in the pipeline ... Notwithstanding the near-term uncertainty, our core business is back on a growth trajectory after the long post-pandemic down cycle."

Strategic Positioning

1. Proprietary High-Voltage GaN: Technology Moat and Market Expansion

Power Integrations’ proprietary GaN (gallium nitride, a wide-bandgap semiconductor known for high efficiency at high voltages) is a core differentiator, with the company being first to market at 1250V and now sampling 1700V devices. This voltage leadership enables unique system-level solutions for 800V data center architectures and next-generation EVs, where competitors relying on TSMC face process risk after TSMC’s announced exit from the GaN foundry business. POWI’s IDM (integrated device manufacturer, a company that both designs and fabricates its chips) model provides control over process and device integration, supporting cost, yield, and performance advantages.

2. Segment Mix Shift: From Consumer to Industrial and High-Power

The company’s revenue mix is shifting decisively toward industrial and high-power applications, including metering, automation, clean energy, and EV traction. This evolution reduces dependence on cyclical consumer appliances, which are currently pressured by tariffs and housing softness, and positions POWI for secular growth as global electrification and efficiency standards rise.

3. Data Center and AI: System-Level Content in Next-Gen Architectures

POWI is targeting AI data center power delivery with its 1250V and 1700V GaN platforms, which support new 800V DC architectures championed by NVIDIA. The company is already shipping into auxiliary power supplies and plans to sample main converter products in 2026, aiming for up to $1,000 content per rack. System-level reliability and integration, rather than discrete components, are the focus, with GaN expected to displace silicon carbide and MOSFETs for performance and cost reasons.

4. R&D Efficiency and Growth Model Reset

New CEO Jen Lloyd is prioritizing R&D efficiency to accelerate product cycles and align development with high-value verticals, with the explicit goal to “invigorate the growth to achieve the model that we set out, the double digit growth model.” This includes adapting teams and processes for the requirements of automotive and data center, and leveraging system expertise to anticipate customer needs.

5. Global Design Wins and Geographic Diversification

POWI is winning designs across regions and end-markets, including new metering wins in Japan and Europe, traction inverters for US heavy equipment, and automotive programs in China, India, and the US. This diversification spreads risk and supports the company’s path to material automotive revenue by 2026, with a target of $100 million by 2029.

Key Considerations

Q2 was a transitional quarter, with strategic pivots and technology milestones offsetting near-term cyclical headwinds. Investors should focus on the company’s ability to execute on its high-voltage GaN roadmap, manage inventory and tariff-driven volatility, and deliver on its double-digit growth ambition through vertical and geographic expansion.

Key Considerations:
