BRONCUS-B (02216) saw its stock price plummet by 5.41% in pre-market trading on Friday, following the release of its interim financial results for the first half of 2025. The significant drop reflects investors' concerns over the company's financial performance.

According to the interim report released late Thursday, BRONCUS-B experienced a substantial decline in its key financial metrics. The company's revenue for the six months ended June 30, 2025, fell sharply to $1.652 million, representing a 55.4% decrease compared to the same period last year. This significant revenue contraction likely contributed to the negative market reaction.

While BRONCUS-B managed to narrow its net loss slightly to $7.792 million, an improvement of 1.9% year-on-year, it wasn't enough to offset concerns about the company's overall financial health. The gross profit also took a hit, dropping by 58.9% to $1.214 million. These figures paint a picture of a company facing considerable challenges in maintaining its market position and profitability, which appears to have prompted the sell-off in early trading.
