China's Zhongding bets $288M convertible on robot joints as car-parts growth slows
What's the deal? Anhui Zhongding Sealing Parts, a 40-year-old Chinese auto-parts maker, has raised US$264M (≈$288 million) in a post-IPO convertible bond issue. The company's controlling shareholder, Zhongding Holding Group, and controllers Xia Dinghu and Xia Yingsong took part, with existing shareholders claiming about 74.6% of the offering.
Where's the money going? The biggest slice — US$100.7M, nearly 40% — funds a core robot-joint manufacturing project. A further US$80M goes to thermal-management and data-centre liquid cooling, US$14.6M to a smart-chassis R&D centre, and US$68.8M to working capital.
Why now? Humanoid robots are moving from trade-show demos to factory pilots, and auto-parts firms are using their manufacturing know-how to break into the supply chain. Zhongding's car-rubber business — seals, cooling pipes, air suspension — is growing in single digits, and its largest segment, thermal management, is shrinking.
What's the endgame? The robot project sits inside Ruisibo, a subsidiary set up in December 2024 with US$6.88M. Once built, it is slated to produce 150,000 harmonic reducers, 150,000 sensors, and 280,000 joints a year. For now it has assembled 60 humanoid robots on contract and ships harmonic reducers in small batches.
By the numbers: Zhongding posted first-half 2026 revenue of US$13.9B, up 2.48% year on year but slowing from 2025. Net profit attributable to shareholders fell to US$935M, hit by a 249-million-yuan loss on financial-asset revaluations and a 49.87-million-yuan foreign-exchange loss.
What could go wrong? Construction runs two years, and depreciation on the new lines will hit the books before orders do — up to US$16.8M a year in added charges. The convertible also carries risk: at US$2.5, the conversion price sits above the 17.38-yuan close on October 26, and if the stock stalls, Zhongding faces a 2.07-billion-yuan redemption. This is its third convertible; the first two converted to equity on rising shares.
The signal: Zhongding is a test case for whether legacy suppliers can pivot their craft into robotics. Rivals are moving fast — Germany's SchaefflerDealroom has a profile for this one. Try Dealroom → recently reported cumulative robot orders of €400 million — and Zhongding's own secured demand, including roughly 300,000 harmonic reducers, offers some footing. Whether new capacity turns into delivered revenue, not just balance-sheet goodwill, is the open question.
