Core Viewpoint - The article discusses a significant labor dispute lawsuit involving AI chip giant Cambricon, where former Vice President and CTO Liang Jun is suing the company for 4.287 billion yuan, which is equivalent to more than two years of the company's profits [1][2]. Group 1: Lawsuit Details - On October 31, Cambricon confirmed receipt of a lawsuit from Liang Jun, who claims a labor relationship existed between October 2017 and February 2022 and seeks compensation for stock incentive losses amounting to 4.287 billion yuan [5]. - The lawsuit's claim is based on Liang's indirect ownership of 11.5232 million shares through an employee stock ownership platform, calculated at a projected price of 372 yuan per share by October 10, 2024 [5]. - Following Liang's departure in March 2022, Cambricon's stock price dropped significantly, but the stock surged dramatically afterward, leading to a current estimated value of the disputed shares at 15.844 billion yuan [6]. Group 2: Background of Liang Jun - Liang Jun, a veteran from Huawei, was recruited by Cambricon's founder Chen Tianshi in 2017 to lead AI chip development, successfully launching the first 7nm AI chip, which was crucial for the company's market entry [8][9]. - Disagreements over the company's strategic direction led to Liang's resignation in March 2022, which resulted in an immediate drop in Cambricon's stock price and market value [9][11]. Group 3: Company Financial Performance - In 2025, Cambricon reported a remarkable turnaround, achieving a revenue increase of 43 times year-on-year in the first half and over 10 billion yuan in net profit, marking a historic shift from losses to stable profitability [19]. - For the third quarter, the company reported a revenue of 1.727 billion yuan, a year-on-year increase of 1332%, and a net profit of 567 million yuan [19]. - The first three quarters of 2025 saw total revenue of 4.607 billion yuan, a 2386% increase year-on-year, with a net profit of 1.605 billion yuan, indicating a solid business-driven profitability rather than reliance on government subsidies [20][21].
