Analysts highlight the company's strategic expansion into the AI infrastructure supply chain as a key growth driver. It is noted that the company began securing substantial orders for AI liquid cooling connectors in 2025. In 2026, it started receiving significant orders for ROSA and TOSA components used in AI optical modules. As the precision requirements for optical modules continue to increase, the company's expertise in precision lathes provides a distinct competitive advantage, allowing it to capture greater market share in this sector. Furthermore, the growing complexity of future liquid cooling connectors is expected to drive increased demand for the company's machine tool products, positioning AI data centers as a sustained driver for future performance growth.
