US China Tensions And Pricing Pressures Will Erode Future Margins

Key Takeaways

• Geopolitical tensions, regulatory shifts, and reliance on key customers heighten risks to supply chain stability, revenue growth, and earnings consistency.
  
• Insufficient R&D and slow adaptation to emerging technologies threaten market position, pricing power, and long-term margin expansion.
  
• Expansion into automotive, industrial, and AI markets, along with a flexible supply chain and premium product focus, positions Diodes for resilient growth and improved profitability.

Manufactures and supplies application-specific standard products in the broad discrete, logic, analog, and mixed-signal semiconductor markets worldwide.

• Diodes faces major risks from rising geopolitical tensions and new tariff regimes, particularly between the US and China, which could disrupt its global manufacturing footprint and customer relationships. This creates the potential for supply chain delays, abrupt shifts in customer demand, and ultimately lost sales opportunities, directly impacting future revenue growth and possibly increasing cost of goods sold, thereby reducing gross margins.
  
• The company's heavy reliance on a limited number of large automotive and industrial customers introduces significant concentration risk. If any key customer shifts suppliers due to market or technology changes, revenue and cash flows could experience sudden, severe declines, leading to earnings instability across future quarters.
  
• Sustained industry trends toward commoditization of discrete and analog semiconductors may accelerate competitive pricing pressure for Diodes, eroding its product differentiation and resulting in diminishing pricing power. This likely outcome puts persistent pressure on both gross and net margins, especially in the event of industry downturns or periods of inventory overhang.
  
• With rapid innovation in semiconductor materials and advanced packaging (such as SiC/GaN), Diodes risks falling behind larger competitors if it cannot ramp up R&D or make substantial capital investments. This shortfall could relegate the company to low-margin, legacy products, while missed adoption of next-generation technologies would hamper long-term revenue and margin expansion.
  
• Heightened regulatory demands for sustainability and more stringent power efficiency requirements are expected to drive up compliance costs for manufacturers. Diodes may face persistently higher operating expenses to meet these regulations, and risks losing business in regions where it cannot update its portfolio rapidly enough, constraining future earnings growth and weighing on free cash flow.

Diodes Future Earnings and Revenue Growth

Assumptions

• This narrative explores a more pessimistic perspective on Diodes compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts.
• The bearish analysts are assuming Diodes's revenue will grow by 6.1% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from 1.9% today to 13.7% in 3 years time.
• The bearish analysts expect earnings to reach $220.1 million (and earnings per share of $1.62) by about July 2028, up from $25.5 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 bearish analyst cohort, the company would need to trade at a PE ratio of 11.8x on those 2028 earnings, down from 95.3x today. This future PE is lower than the current PE for the US Semiconductor industry at 30.9x.
• Analysts expect the number of shares outstanding to grow by 0.15% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 9.59%, as per the Simply Wall St company report.

Diodes Future Earnings Per Share Growth

Risks

• Strong design win momentum and expanding content in high-growth areas such as automotive (including EV, ADAS, and battery management), industrial, and AI server applications positions Diodes to benefit from secular trends toward electrification, intelligent systems, and cloud computing, potentially increasing revenue and earnings.
  
• The company's effective hybrid manufacturing model and global footprint across multiple regions provide supply chain flexibility and resilience, reducing the risk from tariffs or regional disruptions, and supporting stable gross margins and consistent cash flows.
  
• Consecutive quarters of year-over-year revenue growth, improving book-to-bill ratio, and inventory normalization-combined with guidance for continued sequential and annual growth-suggest the company is successfully executing its recovery and expansion, which could lead to gross margin and net income improvement.
  
• Increased focus on higher-value, higher-margin products, ongoing new product introductions, and product mix improvements (especially in analog, power, and Pericom portfolios) create opportunities for sustained gross margin expansion and enhanced profitability over the long term.
  
• Management's confidence is reinforced by a significant share repurchase program, strong balance sheet, healthy free cash flow generation, and the capacity for both organic investment and M&A, all of which provide financial flexibility to fuel further growth in revenue, net margin, and earnings per share.

Valuation

• The assumed bearish price target for Diodes is $43.0, which represents the lowest price target estimate amongst analysts. This valuation is based on what can be assumed as the expectations of Diodes's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $62.0, and the most bearish reporting a price target of just $43.0.
• In order for you to agree with the bearish analysts, you'd need to believe that by 2028, revenues will be $1.6 billion, earnings will come to $220.1 million, and it would be trading on a PE ratio of 11.8x, assuming you use a discount rate of 9.6%.
• Given the current share price of $52.49, the bearish analyst price target of $43.0 is 22.1% lower. Despite analysts expecting the underlying buisness to improve, they seem to believe the market's expectations are too high.
• 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.
