Ningbo Joyson Electronic is one of the world's big airbag and car-electronics groups, and it is now selling "brains," hands and power packs to humanoid robot makers. It trades in Shanghai (600699) and, since November 2025, in Hong Kong (0699). Reports that Tesla audited Joyson's factories for Optimus Gen 3 put it on the list in our Tesla Optimus stocks hub, but Q3 2026 was rough: profit fell 47%. Here is the case for and against.
- Tickers: 600699 (Shanghai) and 0699 (Hong Kong, listed Nov 6, 2025 at HK$22.00).
- Robot products: embodied-AI controllers, AI head assemblies, dexterous hands, energy packs.
- Tesla: reported Optimus Gen 3 factory audits in September 2026; not confirmed by either company.
- Q3 2026: revenue RMB 13.80B (-11%), net profit ~RMB 220M (-47%).
- Valuation: ~21x trailing earnings; A-share near its 52-week low in October.

From Airbags to Robot Brains
Joyson grew through acquisitions, including the assets of Japan's Takata in 2018, into a global supplier of airbags, seatbelts and steering wheels, plus cockpit electronics, battery management and smart-driving controllers. That mix is why it fits the humanoid supply chain differently from Tuopu or Sanhua: instead of actuators, Joyson sells electronics, sensing, power and control. The core business is still huge. In the first half of 2026 revenue was about RMB 28.1 billion, net profit RMB 740 million (+4.4%), and new lifecycle orders reached RMB 44.9 billion (+43.9%), according to the company's H1 release. Overseas gross margin reached about 18.1%, up from roughly 9% in H1 2022.
Inside the Robotics Unit
| Subsidiary | Focus | Status (2026) |
|---|---|---|
| Hyperplane Technology | Embodied-AI controllers ("robot brains") | Central control units delivering |
| Telephix | Dexterous hands | Launched H1 2026 |
| Junebot | Integrated energy for robots | Hybrid solid-liquid packs launched H1 2026 |
| Group | AI head assemblies, body and material parts | Delivering to North American and Chinese customers |
Changjiang Securities' Q3 review (November 4, 2026) says brain controllers, energy management products and mechanical body parts are already in mass production and delivery, and that Joyson works with several Chinese and North American embodied-AI companies. Neither source names customers or gives robotics revenue.
Why electronics matter: a humanoid's head and torso hold the compute, cameras, power distribution and battery. These are closer to what Joyson already builds for cars than to gears and screws. See how Tesla packages them in the Optimus Gen 3 overview.
The Tesla Audits: What Is Reported
- Sep 2025 to Feb 2026A first round of Tesla supplier audits ahead of the Gen 3 redesign checks automotive-grade quality, cycle times, unit costs and overseas manufacturing, per 21jingji.
- Early Sep 2026CLSA reports a Tesla bulk order of about 5,000 units with its core Optimus supply chain and new audits of Tuopu, Sanhua and Joyson (cited by Dolphin Research).
- Sep 16-17, 2026A Tesla team arrives in Ningbo and begins factory audits of Joyson, Tuopu and Sanhua for Optimus Gen 3. The suppliers reportedly already hold Optimus orders of varying size (CnEVPost, citing The Paper).
Not confirmed: neither Tesla nor Joyson has announced an Optimus contract. The audit reports rely on unnamed industry sources, and CnEVPost did not say which parts Joyson would supply.
Tesla's own targets are covered in our Optimus production timeline; supplier audits only matter if those volumes arrive.
Q3 2026: Profit Nearly Halves
| Metric | Q3 2026 | YoY | 9M 2026 |
|---|---|---|---|
| Revenue | RMB 13.80B | -11.0% | RMB 41.89B (-8.6%) |
| Net profit (attributable) | ~RMB 220M | -47.0% | RMB 960M (-14.5%) |
| Adjusted net profit | ~RMB 220M | -48.2% | RMB 870M (-22.4%) |
| New lifecycle orders | ~RMB 61.5B in the first nine months | ||
Source: Changjiang Securities via Gelonghui. Q3 profit was also down 35% from Q2. The broker blames higher prices for memory chips, other electronic components and raw materials, a cost problem that hits electronics-heavy suppliers harder than metal-parts makers. The order book points to recovery: Changjiang forecasts net profit of RMB 1.43 billion in 2026, RMB 1.59 billion in 2027 and RMB 1.83 billion in 2028.
Valuation: Cheap for a Reason?
At about CNY 27 billion, Joyson trades near 21 times trailing earnings and about 19 times Changjiang's 2026 forecast (our estimate), much lower than the robot-heavy names. Sanhua trades at roughly 35 times and Leaderdrive at several hundred times. In other words, the market is valuing Joyson mostly as a car-parts company and putting little on robotics. The A-share fell from a 52-week high of CNY 34.69 to near CNY 18 in October as profits dropped.
Key Risks
- Component costs: memory and chip prices could keep squeezing margins into 2027.
- Auto cycle and price wars: revenue fell 11% in Q3, and Changjiang flags intensifying price competition.
- Unconfirmed robot customers: no named customer, no disclosed robot revenue.
- Complexity: a global, acquisition-built group with many moving parts and currency exposure.

FAQ: Joyson Electronics Stock
Is Joyson Electronics a Tesla Optimus supplier?
It is reported, not confirmed. CnEVPost, citing The Paper and 21jingji, reported in September 2026 that Tesla began factory audits of Joyson, Tuopu and Sanhua for Optimus Gen 3 parts, and that these suppliers already held Optimus orders. Joyson says it delivers robot parts and central control units to leading North American and Chinese customers but does not name them.
What does Joyson make for humanoid robots?
Joyson has three robotics subsidiaries: Telephix for dexterous hands, Hyperplane Technology for embodied-AI controllers and Junebot for energy systems. In the first half of 2026 it launched dexterous hands, AI head assemblies and hybrid solid-liquid energy solutions, and began delivering body parts and central control units.
What were Joyson Q3 2026 results?
According to Changjiang Securities, Q3 2026 revenue was RMB 13.80 billion, down 11.0% year over year, and net profit attributable to shareholders was about RMB 220 million, down 47.0%. Higher memory chip and component costs squeezed margins.
Is Joyson listed in Hong Kong?
Yes. Joyson’s H-shares began trading in Hong Kong under the code 0699 on November 6, 2025, at an offer price of HK$22.00. The company raised about HK$3.25 billion in net proceeds. Its A-shares trade in Shanghai as 600699.
How can I buy Joyson stock from the US or Europe?
The Hong Kong H-share, 0699.HK, is the most accessible line for international investors, since many global brokers trade Hong Kong stocks. The Shanghai A-share 600699 is generally reached through Northbound Stock Connect, QFII or China A-share funds. There is no US ADR.
The Bottom Line
Joyson is the electronics and power play in the Optimus supply chain: three robotics subsidiaries, deliveries to unnamed North American and Chinese robot makers, and reported Tesla audits in September 2026. The core auto business, though, just had a weak quarter, with profit down 47% on chip costs. At around 21 times earnings the robot option looks cheap compared with peers, but it only pays off if Joyson names customers or discloses robot revenue.
