On September 22, YOFC rose 6.9% in regular trading, trading at 195.8 HKD/share, with turnover of 650 million HKD. The rally was driven by the company's scheduled H1 earnings briefing on September 24 and sustained tightness in the global fiber optic supply-demand landscape.

On the news front, YOFC announced it will hold its semi-annual earnings briefing on September 24 via video and online interaction, drawing heightened market attention. Meanwhile, the fiber optic industry continues to see a structural supply-demand reversal — Corning recently signed a landmark ten-year supply agreement with Verizon, while China Mobile's latest fiber cable procurement unit price surged approximately 90% versus the prior round, further confirming the upward pricing trend. YOFC's Q2 results demonstrated significant profit leverage, with revenue reaching 6.114 billion yuan, up 65.4% quarter-over-quarter, and net profit attributable to shareholders of 2.43 billion yuan, surging 390.7% QoQ. H1 net profit totaled 2.925 billion yuan, up 888.88% year-over-year. The broader optical communication sector also strengthened, with CIG up 4.12% and ZJ INNOLIGHT up 4.4%.
