Power Integrations Inc (NASDAQ:POWI) reported financial results for the fourth quarter and full year of 2025, delivering a mixed performance that has elicited a sharp negative reaction from investors in after-hours trading. While the company managed to exceed bottom-line expectations, a sequential revenue decline and a conservative forward outlook appear to be the focal points of market concern.
Earnings and Revenue Versus Estimates
The semiconductor company's fourth-quarter results presented a clear divergence between profit and sales performance relative to Wall Street's forecasts.
- Revenue: The company reported Q4 net revenue of $103.2 million. This figure represents a 13% decline from the prior quarter and a 1.9% decrease from the $105.3 million reported in Q4 2024. It also came in slightly below the analyst consensus estimate of approximately $105.1 million.
- Earnings Per Share: On a non-GAAP basis, which excludes items like stock-based compensation and amortization, Power Integrations reported earnings of $0.23 per diluted share. This surpassed analyst estimates of $0.19 per share by approximately 19%.
For the full year 2025, the company achieved revenue of $443.5 million, marking a 6% increase over the prior year. However, GAAP net income for the year fell to $22.1 million ($0.39 per diluted share) from $32.2 million ($0.56 per diluted share) in 2024.
Market Reaction and Forward Guidance
The market's immediate response to the report was decisively negative, with the stock falling sharply in after-hours trading. This reaction seems primarily driven by the company's guidance for the upcoming first quarter of 2026, which aligns with but does not exceed current expectations.
The company provided the following outlook for Q1 2026:
- Revenue is projected to be between $104 million and $109 million.
- The midpoint of this range, $106.5 million, is essentially in line with the current analyst sales estimate of $108.4 million for the quarter.
While the guidance meets expectations, it does not signal a robust rebound from the Q4 revenue dip, potentially disappointing investors hoping for a stronger growth trajectory in the near term. The company also announced a restructuring plan, reducing its global workforce by 7%, which is expected to incur a charge of $3.5 to $4.0 million in Q1 2026.
Key Takeaways from the Press Release
Beyond the headline numbers, management commentary highlighted several strategic points:
- Industrial Strength: CEO Jen Lloyd noted that full-year growth was led by a 15% increase in the industrial category, driven by record sales in high-power gate-driver products, metering, power tools, and automotive applications.
- Technology Growth: Revenue from the company's PowiGaN™ products grew more than 40% for the full year, indicating strong adoption of its gallium-nitride technology.
- Strategic Positioning: Management expressed confidence in a growing addressable market fueled by trends in AI data centers, electrification, and grid modernization. The restructuring is framed as an effort to align expenses with revenue and free up resources to invest in these long-term growth areas.
- Dividend: The company declared a quarterly cash dividend of $0.215 per share, payable on March 31, 2026, representing a slight increase from the previous $0.21 per share.
Conclusion
Power Integrations' Q4 report paints a picture of a company navigating a period of transition. The ability to beat earnings estimates demonstrates cost management and operational efficiency, particularly through a challenging quarter. However, the market's negative reaction underscores a focus on top-line growth and future momentum. Investors are weighing the company's strong positioning in industrial and high-growth technology segments against the reality of near-term revenue softness and a cautious outlook. The success of its restructuring and its investments in key markets like AI and electrification will be critical to rebuilding investor confidence.
