STMicroelectronics	~40%
Infineon Technologies	~22%
Wolfspeed	~14%
ROHM	~10%
onsemi	~7%
Others	~7%

Wolfspeed has historically maintained leadership in SiC wafer technology, but competitors have been rapidly catching up [8].

The competitive dynamics reveal a race toward larger wafer sizes:

Company	200mm Status	300mm Plans
Wolfspeed	Only company manufacturing SiC devices on 8-inch platform in high volume	Lab breakthrough achieved; volume commercialization path established
Infineon	Products on 200mm SiC from Villach, Austria facility since February 2025	Actively developing 300mm capability [9]
STMicroelectronics	Strong 200mm production	Investment focus on automotive SiC
onsemi	Targeting 8-inch transition after 2025 technical verification	Achieved 50%+ self-sufficiency in SiC substrates via GTAT acquisition [8]
Chinese Players (SICC, TanKeBlue)	Controlling ~40% of SiC wafer market as of 2025	Aggressive pricing creating 30% price decrease in 2024 [8]

• Only company with high-volume 8-inch SiC manufacturing capability [3]
• Largest SiC IP portfolio with 2,300+ patents [1]
• First-mover advantage in 300mm SiC wafer production
• Integrated manufacturing capabilities

The 300mm breakthrough demonstrates that Wolfspeed retains its technological edge despite financial difficulties. According to Poshun Chiu, Principal Analyst at Compound Semiconductor, Yole Group: “This 300mm breakthrough is more than a technical milestone — it unlocks new opportunities for silicon carbide as a strategic material. It clearly demonstrates that silicon carbide is advancing to the next level of manufacturing maturity required for the coming decade of electrification, digitalization, and AI.” [1]

The transition to 300mm wafers offers significant cost advantages [3]:

• 300mm wafers provide 2.25x the surface area of 200mm wafers
• Higher chips per wafer spreads fixed costs over greater volume
• Critical for reducing per-device costs in an inherently expensive material system

The SiC market is projected to reach $1.3 trillion by 2035, growing at an 11.3% CAGR [9], with the automotive segment expected to capture 70.6% market share [9]. Wolfspeed’s technological position positions it to capture share in high-growth applications.

The consensus price target stands at $30.00, representing +62.9% upside from current levels, with 6 analysts rating it a Buy [4].

Wolfspeed faces significant challenges in funding the $1B+ 300mm fab investment [3]:

• Still carrying ~$2.0 billion in debt post-emergence
• Reported $864 million net loss for fiscal year 2024
• Limited access to capital markets given recent bankruptcy

The company has only established a “clear path to future volume commercialization” [1] — not immediate production. Competitors like Infineon already have products shipping on 200mm technology [9].

A securities class action lawsuit was recently transferred to North Carolina federal court, alleging misrepresentations about financial projections [7]. This creates ongoing legal and reputational risk.

Short interest has risen to 64.22% of float, indicating significant bearish sentiment [7]. It would take 4.25 days to cover short positions on average volume.

Commercial success hinges on:

• Post-reorganization cost efficiency
• Securing design wins to validate 300mm SiC advantages
• Competing against entrenched 200mm ecosystems [3]
