AI And Automotive Trends Will Drive Advanced Wafer Demand

Key Takeaways

• Accelerated growth and margin expansion are expected from investments in advanced wafer technologies and rising demand in AI, automotive, and next-gen electronics sectors.
  
• Long-term agreements and industry consolidation provide strong pricing power and earnings stability, insulating Siltronic from market volatility and supporting profitability.
  
• Persistent inventory overhang, rising debt, and competitive threats combine with customer reliance and FX volatility to pressure Siltronic's growth, margins, and financial flexibility.

Develops, produces, markets, and sells hyperpure silicon wafers for the semiconductor industry in Germany, rest of Europe, the United States, Taiwan, Mainland China, South Korea, rest of Asia, and internationally.

• While analyst consensus expects the ramp-up of the Singapore fab to position Siltronic for mid-term growth, this likely underestimates the speed and scale at which the new facility can enable margin and revenue expansion as AI, automotive, and advanced logic demand surge, potentially making Siltronic a major beneficiary of the next upcycle, with gross margin uplift once utilization accelerates.
  
• Analyst consensus highlights pricing stability from long-term agreements covering two-thirds of sales, but the actual duration of current LTAs running through 2028 to 2030 offers unusually high earnings visibility, shielding Siltronic from pricing pressure for years and setting up stable net margins even during periods of heavy industry volatility.
  
• Structural trends, such as exponential semiconductor demand from AI, data center expansion, and 5G/IoT adoption, could sustain wafer order volumes well beyond historical peaks, allowing Siltronic to operate at elevated utilization rates and deliver outsize long-term revenue growth once customer inventories normalize.
  
• Siltronic's leading investments in 300mm and advanced-node wafer technologies, combined with a rapid exit from low-margin small-diameter segments, position it as a strategic supplier for next-gen EVs and autonomous vehicles where silicon content per vehicle is expected to multiply, enhancing both revenue growth and gross margins.
  
• Rising technological entry barriers and ongoing industry consolidation are set to shift more pricing power toward established players, potentially enabling Siltronic to command premium pricing on advanced wafers, driving structural improvements in EBITDA margins and long-term profitability.

Siltronic Future Earnings and Revenue Growth

Assumptions

• This narrative explores a more optimistic perspective on Siltronic compared to the consensus, based on a Fair Value that aligns with the bullish cohort of analysts.
• The bullish analysts are assuming Siltronic's revenue will grow by 9.4% annually over the next 3 years.
• The bullish analysts assume that profit margins will increase from 2.1% today to 5.0% in 3 years time.
• The bullish analysts expect earnings to reach €90.4 million (and earnings per share of €2.88) by about August 2028, up from €29.2 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the more bullish analyst cohort, the company would need to trade at a PE ratio of 28.5x on those 2028 earnings, down from 36.8x today. This future PE is greater than the current PE for the GB Semiconductor industry at 19.1x.
• Analysts expect the number of shares outstanding to grow by 1.34% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 9.81%, as per the Simply Wall St company report.

Siltronic Future Earnings Per Share Growth

Risks

• Sustained customer inventory overhang-especially in memory and power segments-is delaying the recovery of wafer demand, resulting in lower wafer volumes and continued pricing pressure, which can weigh on Siltronic's revenues and net margins for an extended period.
  
• High capital intensity and ongoing CapEx "hangover," particularly from the Singapore FabNext project, have outpaced cash flow generation, causing increasing net financial debt and leading to a risk of underinvestment or cash strain that could negatively affect long-term earnings and financial flexibility.
  
• The business remains exposed to high customer concentration and long-term agreements (LTAs), making Siltronic vulnerable to order postponements, bargaining power erosion, and potential price concessions when contracts are eventually renegotiated, thereby pressuring future revenues and margins.
  
• Chinese and other international competitors are increasing their capacity in 300mm wafers and aspiring to advance technologically, raising the medium-to-long-term risk of market share loss and price erosion, which would directly impact Siltronic's top-line growth and profitability.
  
• Exposure to FX volatility, particularly the US dollar to euro exchange rate and hedging outcomes, introduces uncertainty to both revenues and EBITDA, with currency movements in recent quarters significantly impacting sales and profit translation, thus complicating earnings visibility.

Valuation

• The assumed bullish price target for Siltronic is €62.8, which represents two standard deviations above the consensus price target of €45.88. This valuation is based on what can be assumed as the expectations of Siltronic's future earnings growth, profit margins and other risk factors from analysts on the bullish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of €64.0, and the most bearish reporting a price target of just €35.35.
• In order for you to agree with the bullish analysts, you'd need to believe that by 2028, revenues will be €1.8 billion, earnings will come to €90.4 million, and it would be trading on a PE ratio of 28.5x, assuming you use a discount rate of 9.8%.
• Given the current share price of €35.82, the bullish analyst price target of €62.8 is 43.0% 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.
