Core Viewpoint - The patent dispute involving lidar technology may significantly impact the IPO process of TuDatong, which recently received approval for its overseas listing through a SPAC merger. The lawsuit filed by Hesai Technology raises concerns about potential product bans and financial liabilities that could affect TuDatong's market position and IPO approval [1][14]. Group 1: Patent Dispute - The lawsuit centers on the similarities between TuDatong's new product "Lingque E1X" and Hesai's AT series, with claims of infringement on multiple patents [2][6]. - Hesai's AT series, launched in 2021, has sold over one million units and has established a strong market presence, making the patent dispute particularly sensitive [6][8]. - TuDatong's sudden shift from a 1550nm wavelength technology to a 905nm wavelength technology for the Lingque E1X has raised questions about the legitimacy of its product development [7][19]. Group 2: IPO Process - TuDatong's IPO process has faced multiple setbacks, including failed attempts to list on NASDAQ and the Hong Kong Stock Exchange, leading to its current SPAC listing strategy with an estimated valuation of approximately 10.9 billion RMB [8][14]. - The timing of the patent dispute is critical, as it could directly influence the Hong Kong Stock Exchange's review of TuDatong's listing application [14][19]. Group 3: Financial Performance and Market Position - TuDatong's financial losses have been increasing, with projected losses of $188 million, $219 million, and $398 million from 2022 to 2024, respectively, and cash reserves dwindling to $24.27 million by Q1 2025 [15][16]. - The company's gross margin has been negative, contrasting sharply with Hesai's gross margin of over 40%, highlighting the financial challenges faced by TuDatong [16][19]. - The lidar market is experiencing a significant price drop, with average prices falling from 20,000 RMB to around 2,500 RMB, intensifying competition and further straining TuDatong's financial health [16][19]. Group 4: Market Dynamics - The lidar market is becoming increasingly concentrated, with Hesai holding a 20.3% market share, followed by Huawei and Suoteng, while TuDatong's share has dropped to 12.8% [16][18]. - TuDatong's reliance on a single major client poses risks to its bargaining power and market expansion, which could be exacerbated by the ongoing patent dispute [18][19].
