SoftBank's Regulatory Roadblocks Overshadow a Bruising Week for Tech

SoftBank shares came under heavy selling pressure this week as a pair of setbacks — one regulatory, one procedural — collided with a broader retreat in technology and AI-related equities. The stock's steepest single-day move came Thursday, when it shed 14%, though by the following session the decline had moderated to a loss of 3.9%, leaving the shares at €22.40.

At the centre of the regulatory storm is SoftBank's planned acquisition of ABB's Chinese robotics business, a component of a broader agreed transaction worth $5.375 billion. China's investment security review authority has blocked the deal, ABB confirmed. The Swiss engineering group added that both parties remain in close contact and continue to work on the transaction — a signal of intent, though not yet a workable path forward.

Arm's Results Add to the Pressure

The pullback in SoftBank's shares also reflected weakness in Arm, the chip designer in which SoftBank holds a major stake. Arm reported revenue of $1.44 billion for the second quarter of its 2027 fiscal year, a 27% increase year on year. For the third quarter, the company guided toward $1.54 billion — a figure that landed close to market expectations, according to Reuters.

Selling spread across Japanese stocks with exposure to artificial intelligence and semiconductors more broadly. Investors are worried that tighter US scrutiny of AI infrastructure could put the brakes on investment, reports suggested. SoftBank, with its heavy technology weighting, was among the names caught in that downdraft. The anxiety had already rippled through Asia after AI shares on Wall Street fell, with fears that stricter rules for data centres could crimp demand for AI chips and related infrastructure. That remains an expectation among investors rather than a realised drop in demand.

A Second Transaction Slips

Separately, SoftBank disclosed on 30 October a delay to another planned move: LY Corporation's additional purchase of new LINE MAN Corporation shares for $130 million will now close by the end of January 2027, rather than the end of October as originally scheduled. The parties need more time to coordinate the agreements, the company said. The revised date gives investors a concrete yardstick against which to measure progress.

A Lone Voice of Optimism

Not every signal has been negative. Jefferies upgraded SoftBank from "Underperform" to "Hold" on 28 October, simultaneously lifting its price target from JPY 3,140 to JPY 7,270.

The decisive question for investors is how reliably SoftBank can deliver on its announced initiatives — a convincing answer would be worth more than hoping for a swift turnaround in technology sentiment. The company has said it will publish results for the second quarter of its 2026 fiscal year on 10 November, a date that may prove more instructive than the recent share-price slide alone, provided the figures offer additional clarity on the business's trajectory.

For now, caution has the upper hand: a weak technology backdrop is meeting concrete execution hurdles. A more favourable view of SoftBank would be warranted if progress on its projects and its operating performance were to balance those risks more convincingly. A sharp fall in the share price, on its own, offers no reliable basis for valuation.
