YOFC (06869) saw its shares rise more than 5% in morning trading. As of the time of writing, the stock had increased by 5.59%, reaching HK$196.30, with a turnover of HK$2.256 billion.

According to the Optical Communication WeChat public account, in the first quarter of 2026, the domestic G.652.D optical fiber market continued its strong upward trend, with prices repeatedly hitting new highs and supply-demand imbalances deepening. Unlike the relatively transparent market conditions in the past, optical fiber prices exhibited sharp fluctuations after the Spring Festival, sometimes changing daily, reflecting the severity of the current supply-demand mismatch. Notably, an emergency procurement announcement by Heilongjiang Telecom in March showed that the maximum price for GYTA-24 core optical cables, converted to a per-fiber-kilometer rate, had exceeded 100 yuan, nearly 50% higher than the price in Guangdong Telecom's second tender. However, the announcement was suspended just one day after its release.

In 2025, YOFC reported revenue of 14.252 billion yuan, a year-on-year increase of 16.85%, and a net profit attributable to shareholders of 814 million yuan, up 20.40% year-on-year. In the fourth quarter alone, net profit attributable to shareholders was 344 million yuan, surging 234.23% year-on-year. Huatai Securities pointed out that the company's fourth-quarter profit increased significantly compared to the same period last year, with the quarterly gross profit margin reaching 35.7%, the highest since its listing. The institution is optimistic that, driven by both the rising prosperity of its core optical fiber and cable business and its diversified operations such as optical interconnect components, the company's earnings are expected to see substantial growth.
