CIG's stock price surged 5.14% during intraday trading on Tuesday, continuing its recent positive momentum in the market.

The significant price movement follows the company's disclosure of strong first-quarter financial results, with revenue reaching RMB 1.287 billion, representing a 43.98% year-over-year increase. More notably, net profit attributable to shareholders soared 276.44% year-over-year to RMB 118 million, driven primarily by substantial scaling of its high-speed optical module business.

The earnings explosion comes amid robust global demand for 800G and 1.6T high-speed optical modules fueled by AI computing buildouts in data centers. Additionally, the broader optical communications sector has experienced a collective rally, with industry analysts noting that CPO (co-packaged optics) core supply chain companies stand to benefit from accelerating CPO penetration trends.
