Wolfspeed，何以至此？

Core Viewpoint - Wolfspeed is facing significant challenges despite being a leader in the SiC (Silicon Carbide) sector, with potential bankruptcy looming as the company restructures to improve operational efficiency and financial health [1][3]. Group 1: Company Overview - Wolfspeed has been a pioneer in the SiC field since the 1990s, introducing various sizes of SiC substrates [1]. - The company opened its first 8-inch wafer fab, Mohawk Valley Fab (MHV), in 2022, aiming to be the sole mass producer of SiC devices on this platform by 2025 [1]. - Currently, Wolfspeed's power SiC devices account for approximately 20% of its business, generating around $100 million in revenue in 2020 [3]. Group 2: Market Position and Challenges - By 2024, Wolfspeed's power SiC device revenue is projected to exceed 50% of its total income, growing nearly fourfold to approximately $400 million, positioning it as the fourth largest globally [3]. - The company is struggling to maintain revenue levels in 2024 due to a slowdown in the electric vehicle market, which is impacting the growth of the equipment segment [5]. - The rise of Chinese SiC substrate manufacturers has led to a significant drop in SiC wafer prices, decreasing by 30% in 2024, which has further complicated Wolfspeed's market position [6]. Group 3: Strategic Moves and Future Outlook - Wolfspeed has divested its LED and RF device businesses to focus on power SiC, indicating a potential for further business segmentation [9]. - The transition from a materials company to a device company presents high barriers, and significant capital expenditures will be necessary for future development [9]. - The strategic value of Wolfspeed's assets remains high, particularly in the context of U.S. national security and supply chain independence, as it operates the only fully automated 8-inch high-volume wafer fab owned by a U.S. company [9].
