Until Monday, the turbine and grid equipment trade rested on one comfortable assumption: AI sponsors were locked in. Advance payments had been made, slots reserved years into the future, and GE Vernova’s backlog had grown to a record $197 billion. Then SoftBank disclosed a ¥597 billion ($3.7 billion) charge on power generation-related equipment that is no longer in its revised procurement plans, and that assumption cracked in public for the first time.
The company swung to a ¥1.12 trillion ($7.1 billion) loss in its fiscal second quarter after writing down non-refundable advance payments it made to secure power-generation equipment for its 8-gigawatt Ohio project and other US data centers. Analysts on average expected a profit of ¥129 billion. This is not a rounding error. It is the first time an AI infrastructure sponsor has crystallised a loss of this scale on equipment procurement, and it changes the information set every portfolio manager is working from.
What Actually Happened at GE Vernova
Shares of GE Vernova declined by as much as 9.8% in regular trading following SoftBank’s announcement of a $3.7 billion charge related to its revised equipment procurement strategy for U.S. AI data centers. Approximately 6.2 million shares traded, an increase of about 80% from the 30-day average, against a prior close of $829.34. The stock pared losses to close down roughly 4%, but the intraday range told its own story about how fast conviction can reverse in a name that had been treated as a consensus safe harbour.
GE Vernova said SoftBank remains a valued customer, and there is “no negative or positive financial impact” based on what the company disclosed. JPMorgan wrote in a Tuesday note that if any delays or cancellations were to occur, GE Vernova could shift the order to waiting customers. That is almost certainly true: gas turbine demand is tight, and supplier slot reservations remain a scarce asset.
The Assumption Being Re-rated
The bull case was never really about SoftBank specifically. It was about the structure of the order book: customers pay advance deposits, locking in slots and absorbing cancellation risk. Buyers holding reservations now have a public price for a design change, and suppliers have watched SoftBank take a $2.9 billion loss on non-refundable advances tied to equipment it no longer plans to buy, plus an additional $0.9 billion loss related to contract modifications and settlements. That price is not zero, but it is not prohibitive either for a hyperscaler running a trillion-dollar balance sheet.
The Ohio site has a 20-year lease with OpenAI covering 8 gigawatts of IT capacity. SoftBank CFO Yoshimitsu Goto said the company is conducting a “thorough reassessment” including a review of its procurement strategy, though it has no plans to downsize the project. The reassurance is genuine as far as it goes. What it cannot do is restore the prior assumption that order books are immovable.
Siemens Energy faces the same question. In its fiscal Q2 2026 materials, Siemens Energy said it had 24 gigawatts of commitments in Gas Services that were data center related. Management has said it has seen no cancellations to date, which means the turbulence among AI companies cannot yet be translated into a confirmed order loss. Siemens Energy’s full-year results were due November 11; that report becomes a direct read on whether SoftBank’s move is an isolated case or the opening of a wider pattern.
Stocks to Watch
GE Vernova (GEV). The backlog is real and enormous, the Ohio relationship is intact, and secondary demand should absorb released slots. The risk being repriced is not this year’s revenue: it is the multiple. A business priced on the assumption that every turbine reservation converts on schedule deserves a wider discount than one that now carries visible renegotiation risk. Watch the Q4 slot conversion data closely.
Siemens Energy. Management has said it aims to limit customer concentration in its data center exposure, and it has described data centers as a meaningful but not dominant share of its order book. The cap looks prudent today. The November 11 results call is the event that either confirms the firewall or reveals gaps in it.
First Solar (FSLR). Solar fell alongside turbine names on the SoftBank news despite having no direct Ohio exposure. The read-through matters: if AI sponsors are willing to take $3.7 billion write-downs to change procurement strategies, the entire power equipment order chain becomes subject to renegotiation risk in ways the market was not pricing a week ago. First Solar’s project pipeline deserves fresh scrutiny on that basis.
