This table highlights key strategies and trends shaping the silicon carbide (SiC) industry, especially in automotive applications. SiC’s efficiency boosts EV range while reducing battery size, making it a preferred solution over traditional technologies. ON Semiconductor leads through vertical integration, while Chinese suppliers drive down wafer costs. Long-term agreements, factory scaling strategies, and the complementary rise of GaN technologies further define the competitive landscape.
Silicon Carbide (SiC) is like that elite, specialized tool that does one job spectacularly well. When it comes to electric vehicles (EVs), that job is converting power efficiently. Imagine a high-end espresso machine that brews your coffee perfectly every time, while also using less electricity compared to its clunky predecessor—that’s SiC compared to traditional IGBTs (Insulated Gate Bipolar Transistors). It’s about better performance, higher efficiency, and ultimately, getting more juice out of every battery.
Automakers, especially in the mid- to high-power EV segment, are shifting to SiC because of its ability to reduce the size of the battery needed, which in turn saves costs. SiC can cut battery sizes by 8-10%, which might not sound like much, but when you're talking about batteries worth thousands of euros, the savings pile up. Investors need to understand that these cost savings translate directly to profit margins in an increasingly competitive EV market.

ON Semiconductor’s Strategic Edge: Vertical Integration
ON Semiconductor has been winning the SiC race in part because they do it all in-house—they’re vertically integrated. Imagine baking a cake where you grow your own wheat, grind your own flour, and even milk your own cow for butter. It’s a lot of work, but it means complete control over quality and cost. ON Semi’s ability to scale up their wafer manufacturing has given them a significant edge, especially compared to Infineon, which lacks this level of integration.
Competitors like Infineon and ST Microelectronics are forced to rely on external suppliers for some critical components, which makes it harder for them to scale as quickly or as cost-effectively as ON Semi. This integration means more predictable pricing and the ability to avoid supply bottlenecks—something that’s incredibly valuable in an industry with tight production timelines.

The Rise of Chinese Suppliers in the SiC Supply Chain
The entrance of Chinese suppliers into the SiC market has been a game-changer, particularly in terms of pricing. Picture a crowded marketplace where a new vendor shows up selling apples at half the price—everyone takes notice. Chinese wafer suppliers are aggressively pricing their products, leading to a 25-30% decrease in costs over the past year. This pricing pressure is reshaping the landscape, making it tough for Western companies like Wolfspeed and Coherent, who once enjoyed comfortable profit margins.
From an investor’s perspective, this is both an opportunity and a risk. Lower costs could mean higher adoption rates for SiC, but it also squeezes the margins of established players. Companies that can innovate and maintain a competitive edge, either through technology or through more efficient production processes, are the ones likely to thrive.

Long-Term Supply Agreements: Stability or a Gamble?
One of the key strategies in the SiC market has been securing long-term supply agreements (LTAs). These agreements are like locking in a great rent deal for three years, but with a catch—the price gets renegotiated annually. While this provides some volume security for manufacturers, the pricing remains flexible, influenced by market conditions and external pressures like geopolitical events.
For investors, understanding the dynamics of these LTAs is crucial. The flexibility in pricing means that companies need to stay nimble. If the cost of wafers drops significantly, companies locked into older, more expensive contracts could find themselves at a disadvantage. Conversely, companies with favorable terms can capitalize on cost reductions more quickly, improving their margins.

Leapfrogging in SiC Device Performance
The competition in SiC device performance is like an endless game of leapfrog. ON Semi, Infineon, and ST Micro are constantly releasing next-gen products that edge out the competition—for a few months, at least. There’s no single company that dominates across all performance metrics; instead, each one shines in different aspects, whether it’s power efficiency, thermal management, or cost.
This constant innovation cycle is a double-edged sword for investors. On one hand, it drives technological progress, keeping the market exciting. On the other hand, it means that market leadership is often temporary. The companies that can execute consistently and keep to their product roadmaps are the ones likely to generate steady returns.

Scaling and Automation: The Factory Wars
Scaling up production capacity is crucial in the SiC world, and companies are adopting different strategies to achieve it. Infineon, for instance, is investing heavily in new, fully automated factories. These greenfield projects are like building a brand-new space station—high-tech, expensive, but with the potential for massive efficiency gains.
ON Semi, on the other hand, is opting for brownfield projects—upgrading existing facilities rather than building from scratch. This is more cost-effective and allows them to ramp up production without the same level of CapEx. For investors, understanding these different approaches is key to assessing future profitability and return on investment.

Future Technologies: SiC, GaN, and What Comes Next
The future of power semiconductors isn’t just about SiC—gallium nitride (GaN) is also coming into play, especially in lower voltage applications like fast chargers. GaN is like the nimble younger sibling of SiC, great for certain tasks but not yet ready to take on the high-voltage heavyweight challenges where SiC excels. For investors, this diversification means more opportunities, but also more complexity in deciding where to allocate resources.
The industry is moving towards a mix where SiC takes care of the heavy lifting (high voltage and power) while GaN starts to replace silicon in less demanding roles. This complementary relationship will define the power landscape for the next decade, with each material finding its niche.

Wrap-Up: The Ever-Changing Landscape
The SiC market is evolving rapidly, driven by innovations in manufacturing, aggressive competition from Chinese suppliers, and the continuous push for better performance. It’s like playing a game of chess on a 3D board, where each move impacts the next in unexpected ways. For investors, the key lies in keeping a close eye on technological advancements, supply chain dynamics, and the competitive landscape.
Companies that can adapt to pricing pressures, innovate faster, and scale more efficiently are the ones poised to win. As we look forward, the integration of SiC and GaN technologies will only deepen, making power devices more efficient, compact, and cost-effective. The companies that navigate this complex chess game successfully will deliver strong returns for those who back them.
