CIG's stock price surged 5.79% during intraday trading on Thursday, reflecting strong investor confidence in the company's recent performance and growth prospects.

The rally is primarily attributed to the company's explosive first-quarter financial results, which showed revenue of RMB 1.287 billion, a year-on-year increase of 43.98%, and net profit attributable to shareholders soaring 276.44% to RMB 118 million. This remarkable growth was driven by a significant expansion in the scale of its high-speed optical module business, fueled by robust global demand for 800G and 1.6T optical modules from data centers.

Further supporting the positive sentiment is continued institutional attention, highlighted by a recent shareholder transfer of shares worth HK$370 million (representing 3.49% of equity) from Morgan Stanley Hong Kong Securities to Citibank. The company is actively expanding production capacity at its facilities in Jiashan and Malaysia, while advancing the construction of its Mexico production base to meet growing delivery demands, with management expecting 800G optical modules to remain the primary shipment product this year.
