# News: Four stocks surge as DIAGENS Biotechnology makes its debut

Medical device manufacturer **Hangzhou DIAGENS Biotechnology Co., Ltd.** (2526.HK) went public on Monday, with its stock price more than doubling on the first day. The Hong Kong market welcomed four new stocks that day, setting a record for the most listings in a single day this year.

DIAGENS issued approximately 8 million shares at HKD 99 per share, raising a net amount of about HKD 720 million (approximately USD 92 million). The **Hong Kong public offering** was oversubscribed by 1,000 times, and the international placement was oversubscribed by 2.45 times.

The opening price of the shares more than doubled from the issue price, and during the afternoon trading session, it maintained most of its gains, reaching HKD 215 during the day, an increase of 117%. Based on this, the company's market capitalization is approximately HKD 19.1 billion.

In the first three quarters of last year, DIAGENS' revenue rose more than four times from HKD 19.6 million in the same period last year to nearly HKD 112 million, while the loss during the period narrowed from HKD 50.4 million to HKD 36.3 million.
