Calterah Races for the STAR Market: 31% Market Share, Over 900 Million in Losses, the Berkeley Mentor-Student Duo's Path to Breakthrough in Millimeter-Wave Radar
Calterah Microelectronics (Calterah), a Shanghai-based automotive chip company specializing in millimeter-wave radar chips, has filed for a listing on China's Sci-Tech Innovation Board (STAR Market), seeking to raise 3.49 billion yuan. Founded in 2014 by Dr. Chen Jiashu, a UC Berkeley PhD, and his professor Ali Niknejad, Calterah pioneered the use of CMOS technology for automotive-grade 77GHz radar chips, challenging the dominance of global giants like Texas Instruments.
The company has grown rapidly, with revenue soaring from 206 million yuan in 2023 to 632 million yuan in 2025. It holds a 31.1% share in China's automotive millimeter-wave radar chip market and a 4% global share, with cumulative shipments exceeding 30 million chips for clients including BYD, Geely, NIO, Volvo, and Rivian.
Despite strong market traction, Calterah faces significant financial challenges. It has reported cumulative net losses exceeding 900 million yuan over the past three and a half years, driven by massive R&D spending, which accounted for 147.75% of revenue in 2023. Operating cash flow remains negative, and the company relies heavily on external financing. Other risks include high customer and supplier concentration, with its top five distributors accounting for over 99% of revenue and overseas procurement exceeding 50%. Supply chain security is a concern due to reliance on foundries like TSMC.
The proceeds from the IPO will fund R&D for high-performance radar chips, ultra-wideband (UWB) chips for applications like digital car keys, and a new technology center. Calterah aims to expand beyond automotive into industrial and consumer sectors. However, it faces intense competition, potential price wars, and the long, costly cycle of automotive-grade certification. Its path forward hinges on achieving profitability, maintaining technological leadership, and building a sustainable business model in a fiercely competitive global market.
