Estun Automation's stock experienced a significant surge of 23.57% during intraday trading on Tuesday, reflecting strong investor interest in the company.

The sharp increase appears to be driven by a major industry catalyst, as Tesla has confirmed the conversion of its Fremont factory Model S and X production lines into dedicated humanoid robot production lines, with the third-generation Optimus robot expected to enter mass production in the coming months. This development marks a substantial acceleration in humanoid robot industrialization, boosting sentiment across the entire supply chain.

Additionally, Estun reported exceptional first-quarter financial results with net profit reaching RMB 97.84 million, representing a remarkable 674.64% year-over-year increase. The company's industrial robot shipments ranked first domestically, surpassing foreign brands for the first time, while its newly launched iER series embodied intelligence robots have already been deployed in automotive, electronics, and lithium battery sectors, further strengthening its market position.
