AXTI: Export Permit Uncertainty Will Challenge Margin Strength Moving Forward

Key Takeaways

• Leadership in high-quality substrate materials and easing export headwinds position AXT for strong revenue growth and higher margins in the AI and data connectivity markets.
  
• Diversification into new markets and improved manufacturing processes are set to reduce risk, optimize costs, and support sustained long-term earnings growth.
  
• Reliance on Chinese customers, export permit delays, low margins, and regulatory pressures create significant risks to sales growth, cash flow, and long-term market position.

About AXT

Designs, develops, manufactures, and distributes compound and single element semiconductor substrates.

What are the underlying business or industry changes driving this perspective?

• Accelerating global demand for high-speed data center connectivity and AI infrastructure is driving increased adoption of indium phosphide substrates, where AXT is a top supplier with 40% share; as export permit headwinds ease, this pent-up demand is expected to produce sharp revenue growth and improved utilization of manufacturing capacity.
  
• The upgrade cycle toward higher-speed optical transceivers in AI and cloud applications requires higher-quality, low EPD substrate material-an area where AXT leads technologically-supporting both higher average selling prices and potential gross margin expansion as quality specifications become more stringent.
  
• Ongoing implementation and optimization of manufacturing process efficiencies, particularly yield improvements in gallium arsenide and cost control in China operations, are expected to drive sustained gross margin recovery and enhance net margins over the coming quarters.
  
• Diversification into new end markets such as sensors, automotive (LiDAR, ADAS), and emerging applications (quantum computing, silicon photonics) positions AXT to broaden its revenue base and reduce customer concentration risk, supporting longer-term revenue and earnings growth.
  
• Strategic progress on vertical integration and supply chain control through raw material joint ventures in China enhances AXT's ability to manage input cost volatility, securing stable margins and improving financial resilience.

AXT Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

• Analysts are assuming AXT's revenue will grow by 93.7% annually over the next 3 years.
• Analysts assume that profit margins will increase from 3.1% today to 39.6% in 3 years time.
• Analysts expect earnings to reach $360.8 million (and earnings per share of $3.37) by about August 2029, up from $3.9 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the analysts, the company would need to trade at a PE ratio of 27.5x on those 2029 earnings, down from 1116.9x today. This future PE is lower than the current PE for the US Semiconductor industry at 45.1x.
• Analysts expect the number of shares outstanding to grow by 7.0% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 11.31%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• Persistent delays and uncertainty in obtaining export permits for key products like gallium arsenide and indium phosphide-due to evolving Chinese trade restrictions and geopolitical tensions-risk extending lead times, missing shipments, and creating revenue volatility, particularly for customers outside China, thereby suppressing overall sales growth and straining cash flow.
  
• Heavy dependence on customer demand in China and high revenue concentration among the top five clients (with one customer over 10%) expose AXT to heightened customer concentration risk; any reduction in orders or customer loss would significantly impact revenues and earnings.
  
• Ongoing low gross margins (8.2% non-GAAP in Q2 2025, a substantial decline from 27.6% a year prior) and continued operating losses signal margin compression and cost management challenges that, if unaddressed, may inhibit the company from returning to sustained profitability.
  
• The highly price-sensitive germanium substrate business faces significant input cost pressures from rising raw material prices and difficulties in obtaining export permits, constraining gross margins and limiting opportunities to rebound revenue from this segment.
  
• AXT's exposure to increasing environmental regulations in China-as well as volatility in raw material joint ventures' performance and possible technological substitution toward alternative substrates-pose medium
• to long-term threats to both net margins and AXT's position in its core markets.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The analysts have a consensus price target of $91.6 for AXT 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 $125.0, and the most bearish reporting a price target of just $55.0.
• In order for you to agree with the analysts, you'd need to believe that by 2029, revenues will be $911.9 million, earnings will come to $360.8 million, and it would be trading on a PE ratio of 27.5x, assuming you use a discount rate of 11.3%.
• Given the current share price of $67.45, the analyst price target of $91.6 is 26.4% 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.
