Shares of BYD Company Limited (HKG:1211) plummeted 5.23% in early trading on Friday, following the release of the company's third-quarter financial results. The Chinese automaker reported a significant 33% year-over-year decline in attributable profit for Q3 2025, which fell to 7.82 billion yuan.

According to the company's filing with the Hong Kong Stock Exchange, BYD's earnings per share for the quarter stood at 0.85 yuan, while operating revenue slid 3.1% to 195 billion yuan. The sharp drop in profit appears to have spooked investors, leading to the sell-off in BYD's shares.

The disappointing quarterly results come amid a challenging period for the electric vehicle industry, with increasing competition and concerns about slowing demand in key markets. While BYD reported a 13% increase in operating revenue to 566.3 billion yuan for the first nine months of 2025, the company's attributable profit for the same period fell 7.6% year-over-year to 23.3 billion yuan. This overall decline in profitability, despite revenue growth, suggests that BYD may be facing margin pressures in an increasingly competitive market landscape.
