The article notes market rumors that regulators may be tightening IPO reviews for hard-tech companies, including robotics firms, though this remains unconfirmed. A securities analyst suggested that as more unprofitable firms apply, regulators may enforce stricter quality controls.

According to the Shanghai Stock Exchange (SSE) official website, the IPO review process for Zhejiang Huandong Technology Co., Ltd., a subsidiary of Shuanghuan Transmission, has tightened.
Termination of Spin-off and Listing
Shuanghuan Transmission recently announced that its board of directors has approved a resolution to terminate the spin-off and listing of its subsidiary, Huandong Technology, on the STAR Market (Shanghai's科创板), and to withdraw the relevant listing application documents. The resolution still requires approval from the company's shareholders' meeting.
Reason for Termination
The company stated that the decision was made after careful evaluation, citing significant changes in the market environment compared to when the plan was initially conceived. The move is intended to better coordinate Huandong Technology's business development and capital planning. Shuanghuan Transmission added that terminating the spin-off will not have a material adverse impact on its production, operations, or financial condition.
Ownership Structure
Following the termination, Shuanghuan Transmission will continue to hold a 45.97% stake in Huandong Technology, maintaining it as a controlled subsidiary.
Company Profile
Huandong Technology's product portfolio includes RV reducers and harmonic reducers. RV reducers are its primary products, widely used in high-end manufacturing sectors such as robotics and industrial automation.
Timeline of Listing Efforts
The preparation for Huandong Technology's listing spanned nearly three years:
- September 2023: Shuanghuan Transmission formally initiated the spin-off and listing preparation for Huandong Technology.
- March 2024: The company's board of directors and shareholders' meeting successively approved the IPO-related proposals, finalizing the overall listing plan.
- November 2024: Huandong Technology's STAR Market listing application was accepted by the SSE.
Financial Data
From 2023 to 2025, Huandong Technology's gross profit margins on its main business were as follows:
- 2023: 42.47%
- 2024: 35.36% (a notable decline)
- 2025: 36.57% (a slight recovery, but still below the 2023 level)
Customer Concentration Risk
Huandong Technology faces high customer concentration. Revenue from its top five customers for 2023–2025 was:
- 2023: RMB 285 million (92.12% of total revenue)
- 2024: RMB 283 million (82.87% of total revenue)
- 2025: RMB 343 million (78.34% of total revenue)
Although the concentration ratio has declined slightly year over year, it remains at a high level.
Reliance on a Single Customer
The company is heavily dependent on its largest customer. Revenue contributions from this customer were:
- 2023: RMB 160 million (accounting for up to 58.14% of total revenue)
- 2024: RMB 198 million
- 2025: RMB 213 million
Public information indicates that the largest customer is Estun Automation.
Market Context and Regulatory Environment
Recently, there have been market rumors that hard-tech companies, including those in the robotics and humanoid robotics sectors, may face challenges in their IPO processes if their industry standing is not sufficiently prominent. These rumors have not yet been confirmed by regulators.
Among embodied intelligence companies currently under IPO review, Yuejiang Technology has passed the review, while Leju Intelligence and Yunshenchu have not yet done so.
Industry Commentary
A securities investment banker from a northern China-based brokerage commented that as the number of IPO applications from unprofitable companies increases, the number of substandard applications may also rise. In this context, regulators may require investment banks and sponsors to strictly control the quality of IPO projects, enhance screening efforts, and enforce rigorous review standards even after applications are accepted.
