Emerging EV And AI Data Centers Will Expand High-Efficiency Markets

Key Takeaways

• Leadership in high-voltage GaN technology and ongoing product innovation enables market share gains and improved margins in high-growth, energy-efficient sectors.
  
• Strategic geographic expansion and operational efficiency create a resilient, diversified business with stronger long-term revenue and profitability prospects.
  
• Heavy reliance on consumer appliances, trade headwinds, slow entry into new growth areas, and heightened competition threaten long-term growth, margin resilience, and earnings visibility.

Catalysts

Designs, develops, manufactures, and markets analog and mixed-signal integrated circuits (ICs), and other electronic components and circuitry used in high-voltage power conversion.

• Growing adoption of advanced power conversion technologies in EVs, AI data centers, renewable energy, and modern power grids is expected to drive long-term expansion of Power Integrations' addressable market, supporting sustained revenue growth over time.
  
• Power Integrations' proprietary high-voltage GaN technology (currently unmatched at 1250V and 1700V) positions the company to capture premium share in emerging high-density, high-efficiency end-markets such as next-gen AI data centers and automotive, which is likely to boost both average selling prices and gross margins.
  
• Ongoing product innovation, especially the integration of digital control and development of disruptive, system-level ICs/modules, enables further market share gains, design wins, and higher-margin business as demand shifts toward energy-efficient solutions in appliances, metering, and industrial automation, positively impacting overall earnings and net margins.
  
• Strategic expansion in geographies with secular infrastructure build-outs (e.g., smart meters in India, metering in Japan and Europe, and automotive globally) provides diversified revenue streams and a more resilient business mix, mitigating short-term volatility and supporting operating leverage.
  
• Commitment to operational efficiency and enhanced R&D productivity under new CEO leadership aims to accelerate time-to-market for new products and capture growth in high-value sectors, improving both revenue growth and long-term profitability.

Power Integrations Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Power Integrations's revenue will grow by 14.7% annually over the next 3 years.
• Analysts assume that profit margins will increase from 8.6% today to 18.0% in 3 years time.
• Analysts expect earnings to reach $117.6 million (and earnings per share of $2.08) by about August 2028, up from $37.1 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 42.2x on those 2028 earnings, down from 72.1x today. This future PE is greater than the current PE for the US Semiconductor industry at 28.6x.
• Analysts expect the number of shares outstanding to decline by 0.95% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 10.11%, as per the Simply Wall St company report.

Power Integrations Future Earnings Per Share Growth

Risks

• The company is currently experiencing significant near-term headwinds due to tariffs and global trade uncertainty (especially in appliances), and ongoing exposure to tariff escalations or protectionist policies could dampen international sales growth, increase operational costs, and reduce revenue visibility over the long term.
  
• Power Integrations' core business remains highly concentrated in consumer appliances (~50% of consumer revenues), which face cyclical sensitivity to housing markets and macroeconomic factors; long-term stagnant demand or prolonged inventory corrections could compress both revenue and margins in these foundational markets.
  
• While the company has proprietary high-voltage GaN technology and is making progress in emerging segments like automotive and AI data centers, it is not yet on approved vendor lists for critical customers (e.g., NVIDIA), which limits the speed and certainty of penetration; failure to secure or scale major design wins may delay or constrain revenue and earnings growth in these high-potential end markets.
  
• Industry competitive risks remain elevated from lower-cost Asian rivals and alternative power management technologies (e.g., silicon carbide, commoditized MOSFETs), which could erode Power Integrations' pricing power and gross margins, especially in mainstream applications as the industry shifts toward higher efficiency standards and broader adoption of next-generation architectures.
  
• Execution risk in new product development and end-market diversification is meaningful: challenges in efficiently scaling R&D, adapting internal processes for more complex automotive/data center markets, or delays in bringing differentiated products to volume may result in slower innovation cycles, lost market share, and below-target long-term earnings growth.

Valuation

• The analysts have a consensus price target of $68.8 for Power Integrations based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $75.0, and the most bearish reporting a price target of just $60.0.
  
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $653.3 million, earnings will come to $117.6 million, and it would be trading on a PE ratio of 42.2x, assuming you use a discount rate of 10.1%.
  
• Given the current share price of $47.49, the analyst price target of $68.8 is 31.0% higher.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
