On June 9, Horizon Robotics-W fell 3.17% in regular trading, trading at HKD 4.91/share with trading volume of HKD 91.53 million, continuing to slide after breaking below the HKD 5 psychological barrier.

On the news front, BYD officially announced mass production of China's first 4nm automotive-grade autonomous driving chip, Xuanji A3, with single-chip computing power of 700 TOPS and over 2,100 TOPS when three chips are linked. As a core OEM client, BYD's in-house chip development has triggered deep market concerns over the outlook for third-party autonomous driving chip suppliers. Since BYD's announcement, Horizon Robotics and Black Sesame Intelligence have seen combined market capitalization losses exceeding HKD 8 billion.

Simultaneously, the company's annual report revealed a full-year net loss of RMB 10.469 billion, swinging from profit to loss. Product business gross margin declined sharply from 46.4% to 34.5%, a drop of nearly 12 percentage points. Multiple negative factors continue to weigh on valuation amid persistent concerns over the company's profitability trajectory.
