Executive Summary

China's government has barred SoftBank from taking over ABB's robotics business inside China. SoftBank agreed last October to buy the whole of that business at an enterprise value of $5.375 billion, and the Chinese antitrust review cleared the deal this February. One gate was left, the foreign investment security review, and that is where it turned over.

What the review caught on was not a plant or a patent. It was data. The issue, as reported, was that the production and motion records ABB robots have built up in Chinese factories could be moved out of the country and used to train AI models. SoftBank's standing as a major investor in OpenAI is cited as enlarging that concern. China is the largest market for ABB's robotics business at about 30 percent of its revenue, so the arithmetic of the deal does not hold with that one country taken out.

Sections 1 through 4 follow the facts and figures confirmed by news reporting and official announcements. Section 5, on what a company gathering or receiving robot data should write down at the contract stage, is this article's reading.

One Notice Stopped a $5.4 Billion Deal

ABB had planned to carve its robotics division out and list it separately. SoftBank came forward last year offering to buy all of it, the plan turned into a sale, and on October 8, 2025 an agreement was announced at an enterprise value of $5.375 billion. It was the largest piece in the portfolio Masayoshi Son has been assembling since naming physical AI as his next frontier.

The year or so that followed belonged to the reviews. The competition authority's antitrust review cleared in February, and the industry expected the remaining procedures to finish without trouble. The brake came at the last gate.

The date was November 4. SoftBank received notice that day from the security review authority that it could not take over ABB's robotics business inside China. The Financial Times reported it first a day later, and ABB confirmed the facts. SoftBank carried the same content in an official press release on November 6, adding only that it would announce whatever it decides from here as its disclosure obligations require. Laid out by date, the course since the agreement was announced runs as follows.

Date What happened
October 8, 2025 SoftBank announces an agreement to acquire the whole of ABB's robotics business (enterprise value $5.375 billion)
February 2026 Chinese antitrust (competition) review clears the deal
November 4, 2026 SoftBank receives notice from the Office of the Working Mechanism for Foreign Investment Security Review barring the acquisition inside China
November 5, 2026 The Financial Times reports it first and ABB confirms the notice. SoftBank's shares fall 6.77 percent on the Tokyo exchange
November 6, 2026 SoftBank issues an official press release carrying the notice
November 7, 2026 Bloomberg reports that the two companies are examining a plan to carve the China business out

The date of receipt is the one SoftBank gave in its November 6 announcement, and it falls a day apart from the date of first reporting.

The market answered at once. SoftBank's shares gave up 6.77 percent on the Tokyo exchange the day of the report and were pushed down 11 percent across the week. Technology shares were weak together that week, though, so the whole of the fall is hard to charge to this event. ABB's shares fell a little over 1 percent on the day and more than 5 percent on a weekly basis. The ABB robotics division being sold employs about 7,000 people, and its 2024 revenue of $2.3 billion is around 7 percent of group revenue.

The two companies issued only a short joint statement. It said they are in close dialogue and working constructively on the transaction. Nothing in it said they would drop the deal, and nothing said they would look for another route.

The Review's Target Was the Records the Robots Keep

The notice came from the Office of the Working Mechanism for Foreign Investment Security Review (外商投资安全审查工作机制办公室). Its secretariat is housed within China's National Development and Reform Commission (国家发展和改革委员会), and it takes in and reviews, ahead of time, deals in which foreign capital enters and acquires real control in areas such as national defense, energy, important equipment manufacturing and core technology. The governing rules, the Measures for the Security Review of Foreign Investment (外商投资安全审查办法), took effect in January 2021 and run in two stages: a general review that moves to a special review when a deal is judged capable of affecting national security.

No official reason has been made public. The issue carried in news reports is consistent. The production and motion records ABB robots have piled up while running in Chinese factories could pass to Japan and be used to train AI models. The Financial Times noted that SoftBank's position as a major investor in OpenAI gave the worry extra weight. That draws a picture of records from Chinese manufacturing floors flowing into the models of a Western AI company.

The record an industrial robot leaves is thicker than it sounds. The angle at which a welding torch went in, the force with which a gripper closed and opened, the places where the same process went off course over tens of thousands of repetitions — all of it remains as coordinates and timestamps. This becomes the teaching material for a robot. It is a channel through which the skill a plant has learned can enter a model while the plant stays where it is, and that is where the review fixed its attention. The diagram below shows which passage this review cut.

Where the deal was cut off The flow stopped where records cross a border Robots in Chinese factories Over 90% of customer volume local Production and motion records Coordinates, force, cycles, defects Border Security review refusal Training AI models abroad OpenAI investment raised the issue Ownership of equipment, patents and brands already cleared the February antitrust review. The question that stayed to the end was whether the records cross a border.

The authorities were not holding a refusal alone from the start. While the review ran, terms are reported to have passed back and forth: hand part of the robotics business to a Chinese owner, and keep some intellectual property inside China. The sense of it was wariness about manufacturing capacity leaving whole. Those terms were not accepted, and the review ended in a refusal.

The structure of the deal cleared in full, and data was what remained to stop it. If what a buyer pursuing physical AI meant to purchase was the records the equipment had accumulated rather than the equipment, then the security review looked at exactly those records.

China Is Both the Biggest Market and the Factory Floor

Cross-border acquisitions do not all get caught this way. This one snagged so heavily because of the place China holds in ABB's robotics business. By revenue, about 30 percent comes from China. It is the largest market of any single country, and in the third quarter of this year the China business grew 32 percent.

Production is the heavier side. More than 90 percent of the robots sold to Chinese customers are made in China. ABB Engineering in Shanghai is ABB's global robotics headquarters and a base that carries research, development and production together. Buying the division means buying both the brain and the hands.

Widen the frame to ABB Group as a whole and the scale of its China organization comes out more clearly. There are about 30 local entities, and close to 15,000 people work across some 130 cities. The sales network reaches 700 cities. These numbers describe ABB China in total, so they point at something other than the 30 percent revenue figure, which belongs to the robotics division alone.

Some foreign outlets wrote that China accounts for more than 90 percent of demand for ABB robots, which reads as a description mixing the local production ratio with the revenue share. The figures that cross-check are about 30 percent of revenue, and more than 90 percent local production of the volume for Chinese customers. Revenue share and production share are different measures to begin with.

Can the Deal Survive by Splitting in Two?

The refusal notice is not the end of the deal. The bar falls on SoftBank taking the ABB robotics business inside China, and the business in the rest of the world stays outside it. Bloomberg reported that the two companies and their advisers are examining three routes.

  • • Separating the China business — carve the Chinese entity out into a company under different ownership and let SoftBank take the rest. It is understood to be the route SoftBank favors, though the discussion is still at an early stage.
  • • Selling the China business to a third party — find another buyer. The value being talked about is $2 billion to $3 billion, well under what the original deal put on it.
  • • Going back to a spin-off listing — return to the plan ABB drew up at the start. It is judged awkward, since the sale agreement is already signed and the market is in no mood to welcome a new listing.

Whichever way it goes, ABB's arithmetic is thrown off. Citigroup analyst Martin Wilkie estimated that this brake could cut nearly in half, to around $5 billion, the capacity ABB had to put the sale proceeds toward other acquisitions. On the SoftBank side, the price of credit default swaps, which trade the risk of default, rose to 466 basis points, putting the market's caution into a number. Neither company is commenting further.

This is not the first case of the year either. Last April the same review body ordered Meta to unwind its agreement to buy Manus, a Chinese AI startup, for $2 billion. Two cases in seven months, and in both the asset had AI and data attached to it. China's view of foreign capital deals with advanced technology mixed in does not differ between them.

Why Pebblous Is Watching This Deal

In corporate acquisitions data was an accessory for a long time. Once plant and equipment, patents and trademarks, people and contracts each had a price put on them, data was treated as something that came along inside. This review turned that order around. If one piece of data can remain and stop a deal after everything else has cleared, then data is now an asset that has to take a line of its own in due diligence.

Anyone gathering records out of robots or equipment will find this hard to write off as someone else's problem. When foreign investment comes in, when a business is handed over, when data is licensed, the boxes a contract leaves empty turn into the risk. Three things are worth checking.

  • • Who is written down as the owner of the records — the company that sold the robot, the factory that runs it, and the supplier of the operating software all reach the same records. Leave ownership unwritten and you can take over the equipment without taking the records it accumulated.
  • • Where the records are kept and how far they may travel — storage location and the terms for transfer out of the country are separate clauses. A promise to hold data on domestic servers and a promise not to use it for training abroad do not come bundled as one.
  • • Whether the right to use the records for model training is written separately — using data for quality control or fault analysis is a different purpose from using it to train a model. A permission taken in one lump guarantees neither of the two properly later on.

This blog has covered a scene where the same question came up from the opposite direction. When a US review body looked at SoftBank's purchase of a different robotics institute, the issue there too was whether the records a robot learned from cross a border. SoftBank has faced that same question on both sides of the Pacific this autumn. It also means the move toward states treating robot data as something to be controlled is not one country's situation.

This is what Pebblous keeps in view while putting data into a state AI can use straight away. Unless it is set out which records came from where, where they are held, and who may use them for what, no amount of lifting quality answers the first question of whether the data may be used at all. Attaching provenance and rights to data is, before it is a procedure for meeting a rule, the work of establishing that data as an asset.

Editor's Note

This story is not over. This article sets down what had been confirmed through early November, and carving the China business out is an option under negotiation rather than an agreed structure. Chinese authorities have never given an official reason. The account that the issue was data rests on reporting from several outlets, and that is noted here.

Thank you for reading this far. If you are gathering records out of robots or equipment, it is worth looking for the place in your contract where the owner of those records and their storage location are written down. Should you go looking and find an empty box, we would be glad to hear which box it was.
