On June 23, Guanghe Technology fell 3.01% in regular trading, trading at 173.8 HKD/share, with turnover of 23.753 million HKD.

On the news front, the stock previously rallied alongside the broader PCB sector and hit a near one-year high of 206.66 HKD intraday on June 17, after which profit-taking pressure intensified. The company also announced plans to issue A-share convertible bonds raising up to 3.6 billion RMB for its Yunqing Smart Manufacturing Base Phase II project and high-multilayer production line upgrades, while separately planning a 6 billion RMB investment to build a smart manufacturing headquarters in Dongguan. A Citibank research note highlighted that major copper clad laminate manufacturers capacity growth stands at just over 20%, significantly lagging downstream PCB expansion, concentrating pricing power upstream and squeezing PCB makers margins. Sector peers KB Laminates fell 5.17%, Kingboard Holdings fell 4.82%, and VGT dropped 6.26%, reflecting broad industry-wide weakness.
