Ubtech Robotics Bolsters Korean Alliance and Boardroom Grip Amid Humanoid Revenue Surge

The Chinese robotics champion is moving on two fronts simultaneously. While its humanoid Walker S2 gets a training partner in South Korea, Ubtech Robotics is tightening control over a recent acquisition without renegotiating the price tag. The twin moves underscore a strategy that blends operational expansion with governance discipline.

Polaris AI, a Korean technology firm, confirmed on 28 May 2026 that it has started specialised engineering training for the Walker S2 humanoid robot. The industrial-grade model carries up to 15 kilograms of payload and features an automatic battery-swap system, allowing uninterrupted use in manufacturing, logistics and infrastructure inspection. Polaris plans to leverage Ubtech’s software development kit to build custom solutions, deploying the systems across its subsidiaries from automotive suppliers to pharmaceutical logistics.

The announcement came just one day after Ubtech signed a supplementary agreement on 27 May 2026 that sharpens its influence over Zhejiang Fenglong Electric, the target of an ongoing takeover. The board of the target company will be expanded from seven to eight directors, and Ubtech secures the right to nominate seven of them. Crucially, the economic terms of the deal remain untouched: no new purchase price, no additional financing, and no revised stake percentage. The acquisition involves a 29.99% share purchase plus a tender offer for a further 13.02%, approved at Ubtech’s first extraordinary general meeting on 10 March 2026.

The tender component was completed on 24 April 2026, with Ubtech acquiring 28,450,000 A-shares at RMB 17.72 each, bringing its total holding to 93,979,906 A-shares or roughly 43.01% of the capital. The governance change therefore clarifies post-deal control rather than altering the transaction’s mechanics.

Should investors sell immediately? Or is it worth buying Ubtech Robotics?

The market, however, has so far greeted the developments with caution. Ubtech shares traded at EUR 11.94 on Thursday, down 7.83% from the previous close of EUR 12.96. The stock has dropped 17.63% since the start of the year and sits nearly 30% below its 52-week high of EUR 16.95. Over the past 30 days, the shares still show a 5.83% gain, suggesting some underlying resilience.

That resilience may stem from Ubtech’s accelerating financial performance. For the fiscal year 2025, the company reported revenue of RMB 2.001 billion, a jump of 53.3%. The standout segment was full-size humanoid robots and related services, which surged from RMB 35.6 million to RMB 820.6 million, becoming the largest single revenue source. Gross profit climbed to RMB 753.8 million, pushing the gross margin from 28.7% to 37.7%. Yet Ubtech remains loss-making: the net loss narrowed to RMB 789.8 million from RMB 1.1599 billion a year earlier, a reminder that rapid scaling still carries a cost.

The Polaris AI tie-up positions Ubtech within a broader wave of Chinese robotics momentum. The nation has been the world’s largest industrial robot market for over a decade, accounting for 54% of global installations in 2024. Last year marked a tipping point for humanoids: Chinese manufacturers, including Ubtech, delivered 81% of all humanoid robots worldwide, and for the first time Chinese firms sold more units domestically than abroad. Regional governments are now aiming to deploy 10,000 to 20,000 humanoid units by 2027, providing a visible demand pipeline.

For investors, the immediate test lies in execution. The Walker S2 programme, trained by Polaris AI and poised to serve as a benchmark for specialised industrial applications, must show it can scale production without widening losses. The tightened grip over Zhejiang Fenglong Electric, meanwhile, gives Ubtech the boardroom lever to integrate that business more deeply into its humanoid supply chain. The next quarterly report will reveal whether the governance overhaul can match the revenue growth.
