Electrification And Digitalization Will Accelerate SiC And GaN Expansion

Key Takeaways

• Accelerated growth in automotive and Edge AI segments, aided by robust design wins, expanding ecosystem, and advanced microcontroller launches, is set to boost margins and leadership.
  
• Strategic manufacturing diversification and major capacity investments enhance resilience to geopolitical risks, positioning for strong multi-year revenue and net margin expansion.
  
• Rising trade barriers, high inventory, manufacturing transition risks, and intensifying global competition threaten STMicroelectronics' margins, revenue stability, and long-term competitiveness.

Designs, develops, manufactures, and sells semiconductor products in Europe, the Middle East, Africa, the Americas, and the Asia Pacific.

• Analyst consensus expects automotive microcontroller launches in 2025–2026 to drive growth, but the scale of STMicroelectronics' design wins-including across ADAS, electrification, and Tier 1 OEMs globally-positions the firm for market share gains well above consensus, likely fueling a sustained acceleration in automotive segment revenues and commanding higher blended ASPs.
  
• While analysts broadly highlight strong Edge AI momentum, they may be underestimating the doubling pace of project deployment and ST's expanding developer ecosystem; together with new 40-nanometer and sub-40-nanometer MCU lines, this could power outperformance in microcontroller revenue and margin expansion as ST cements leadership in high-growth AI-at-the-Edge markets.
  
• STMicroelectronics' extensive China-for-China manufacturing partnerships-spanning SiC and GaN-and diversified global footprint insulate it from trade/tariff disruptions, positioning the company not only to gain share from U.S. peers but also to attract local OEM wins in a geopolitically fragmented market, supporting resilient revenue growth and improved operating leverage.
  
• The surge in demand for industrial automation, electrified transport, and renewable energy is converging with ST's aggressive pipeline in power management ICs, silicon carbide, and MEMS sensors; as downstream inventory normalizes, ST stands ready for outsized top-line recovery and multi-year growth inflection, with operating margins benefiting from product mix shift.
  
• Large-scale investments in 300-millimeter silicon and 200-millimeter silicon carbide capacity-with legacy fab optimization-are set to unlock significant productivity and fixed-cost absorption by 2026–2027; combined with high triple-digit million dollar annual cost savings, this points to a structural uplift in net margins and cash flow not fully priced into the current equity valuation.

STMicroelectronics Future Earnings and Revenue Growth

Assumptions

• This narrative explores a more optimistic perspective on STMicroelectronics compared to the consensus, based on a Fair Value that aligns with the bullish cohort of analysts.
• The bullish analysts are assuming STMicroelectronics's revenue will grow by 10.3% annually over the next 3 years.
• The bullish analysts assume that profit margins will increase from 8.9% today to 15.6% in 3 years time.
• The bullish analysts expect earnings to reach $2.6 billion (and earnings per share of $3.38) by about July 2028, up from $1.1 billion 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 16.8x on those 2028 earnings, down from 26.3x today. This future PE is lower than the current PE for the GB Semiconductor industry at 20.1x.
• Analysts expect the number of shares outstanding to decline by 0.98% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 8.67%, as per the Simply Wall St company report.

STMicroelectronics Future Earnings Per Share Growth

Risks

• The persistent global trend of deglobalization and increased trade restrictions poses significant risks to STMicroelectronics' cross-border supply chains; ongoing uncertainty around tariffs and market access, especially in automotive and industrial end markets, could limit revenue growth, raise operating costs, and pressure margins.
  
• The company faces elevated cyclical exposure to automotive and industrial segments, both of which accounted for steep year-over-year revenue declines (about 39% in Automotive and 32% in Industrial in Q1 2025); continued weak demand or further cyclical downturns could result in further revenue volatility and margin compression.
  
• There is evidence of excess inventory in key channels, with inventory days reaching a high of 167 and lingering channel inventory in Europe and the Americas; prolonged inventory clearance cycles, combined with unused manufacturing capacity, may continue to dampen gross margins and reduce earnings in the near to medium term.
  
• Despite ongoing cost control and factory modernization efforts, STMicroelectronics' heavy capital investment requirements to support manufacturing scale transitions (from 150mm and 200mm to 300mm silicon and silicon carbide) risk falling short if end-market demand does not recover as expected, threatening operating leverage and long-term profitability.
  
• The rising complexity and escalating cost of advanced manufacturing nodes, coupled with intensifying competition from Asian semiconductor firms and increasing vertical integration by OEMs, may erode STMicroelectronics' technological competitiveness and pricing power, ultimately risking revenue momentum and long-term margin expansion.

Valuation

• The assumed bullish price target for STMicroelectronics is €33.25, which is the highest price target estimate amongst analysts. This valuation is based on what can be assumed as the expectations of STMicroelectronics'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 €33.25, and the most bearish reporting a price target of just €18.94.
• In order for you to agree with the bullish analysts, you'd need to believe that by 2028, revenues will be $16.5 billion, earnings will come to $2.6 billion, and it would be trading on a PE ratio of 16.8x, assuming you use a discount rate of 8.7%.
• Given the current share price of €27.66, the bullish analyst price target of €33.25 is 16.8% 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.
