On the news front, market rumors suggest that Tesla Motors (TSLA) has launched a new round of mass-production factory audits for its robotics business. According to a report by Shanghai Securities News, a source from the local industrial chain in Ningbo confirmed to the reporter that Tesla's relevant team has already inspected the robotics businesses of Ningbo-listed companies including JOYSON ELEC. Several of these listed companies had previously cooperated with Tesla for many years on new energy vehicle components, and some of their robot components are expected to be adopted in Tesla's mass production of the humanoid robot Optimus.

Citi believes that the audit and the upcoming capacity ramp-up are positive for Chinese Optimus suppliers, and could boost investor sentiment in the robotics theme after valuations were de-rated downward since the end of May. Citi estimates that Tesla's Optimus exposure to JOYSON ELEC's net profit in 2027 is approximately 5%.
