Guanghe Technology's stock plummeted 5.02% during intraday trading, extending recent declines. The sharp drop coincides with a significant lock-up share expiry event, which has increased the supply of tradeable shares and created selling pressure in the market.

According to market information, multiple tranches of restricted shares became eligible for trading, including equity incentive shares totaling approximately 15.03 million shares and an additional commitment tranche of approximately 71.89 million shares valued at around 1.682 billion HKD. This influx of newly tradeable supply has weighed on investor sentiment despite the company reporting strong fundamental performance, with Q1 revenue surging 71.35% year-over-year and net profit increasing 63.31% year-over-year, driven by robust AI server PCB demand and Thailand factory capacity expansion.

The broader Electronic Components sector also showed weakness during the session, contributing to the downward pressure on the stock as investors reacted to the increased share supply from the lock-up expiry.
