On June 12, Guanghe Technology rose 5.78% in regular trading, trading at 171.2 HKD/share, with turnover of 36.3 million HKD.

On the news front, PCB concept stocks opened broadly higher across the board. KB Laminates surged over 9%, Kingboard Holdings gained over 6%, and Shenghong Technology rose over 5%. The rally was driven by multiple catalysts: as of June 11, 13 PCB manufacturers had announced expansion plans this year with total investment exceeding 60 billion yuan, signaling robust downstream demand fueled by AI computing buildout.

Meanwhile, Citi issued a research note highlighting that major CCL manufacturers capacity growth this year is only slightly above 20%, significantly lagging downstream PCB expansion pace. The bank warned that as Q3 AI demand ramps up, some PCB makers may face CCL allocation shortfalls. Additionally, the Middle East conflict has disrupted approximately 70% of global high-end PPE resin supply, a critical raw material for advanced PCBs, further tightening the supply chain and supporting sector-wide price momentum.
