CIG's stock soared 5.71% intraday on Monday, driven by robust first-quarter financial results and favorable industry conditions.

The company reported Q1 revenue of 1.287 billion yuan, up 43.98% year-over-year, while net profit attributable to shareholders surged 276.44% year-over-year to 118.3 million yuan. The growth was fueled by strong global demand for 800G and 1.6T high-speed optical modules, with order volumes expanding significantly alongside deepening client cooperation.

Additionally, the supply-demand gap for indium phosphide chips continues to widen amid surging global demand, tightening supply conditions and supporting potential price increases for optical chips, which further benefits CIG's high-speed optical module business.
