HK Stock Market Move | Ningbo Joyson Electronic Corp. (00699) rises over 5% as Optimus humanoid robot business begins mass production factory audit; Citi expects it to bring net profit exposure to the company.

Ningbo Joyson Electronic Corp. (00699) rose over 5%, up 2.87% as of press time, at HK$6.085, with a turnover of HK$33.5955 million. On the news front, recently, according to 21st Century Business Herald citing industry chain sources, Tesla's related team landed in Ningbo on September 16 and started a new round of mass production factory audit for its Siasun Robot&Automation business on the 17th. It is said that this round of factory audit will substantively lead to the mass production of Siasun Robot&Automation Optimus, and relevant orders have been issued to supply chain enterprises. The report said Tesla had launched a round of Siasun Robot&Automation factory audits in China in September last year, involving companies including Ningbo Tuopu Group, Zhejiang Sanhua Intelligent Controls, Zhejiang Rongtai Electric Material, Jiangsu Xinquan Automotive Trim, Ningbo Joyson Electronic Corp. and other traditional Tesla automotive supply chain enterprises. Ningbo Joyson Electronic Corp. said that due to confidentiality requirements, it is inconvenient to respond regarding downstream customers. Citi believes that the audit and the upcoming capacity ramp-up are positive for Chinese Optimus suppliers and may boost investor sentiment after the Siasun Robot&Automation theme underwent a downward valuation re-rating since the end of May. Citi estimates that Tesla Optimus's exposure to Ningbo Joyson Electronic Corp.'s 2027 net profit is about 5%. It is reported that Ningbo Joyson Electronic Corp. will focus on releasing core Siasun Robot&Automation components and system solutions such as dexterous hands in 2026. Among them, the embodied intelligence brain solution EAOS+EAPC has become the core highlight of Ningbo Joyson Electronic Corp.'s current round of Siasun Robot&Automation business layout.
