Fujikura Sinks With Chip Peers as German Fusion Study Stays in the Lab
Published on 10/30/2026 at 15:02 | Editorial boerse-global.de
Fujikura shares fell 7.9% on Thursday, caught in a broad retreat across Japanese technology names rather than any company-specific disclosure. The drop came as the Nikkei at one point surrendered as much as 3%, with semiconductor-related stocks leading the decline, according to Reuters.
The trigger lay in the US, where results from Amazon and Intel stoked doubts about whether the returns on artificial intelligence spending justify the outlay — and about how much more capital the build-out will demand. Those twin concerns rippled through Japan's AI and chip complex, dragging Fujikura down alongside its peers. Reuters did not tie the cable maker's move to any single catalyst, and no company-level cause has been confirmed.
A German Supply Chain, Still on the Drawing Board
Separately, Fujikura's announced cooperation with Proxima Fusion remains firmly in the exploratory stage. The two companies have signed a letter of intent to examine the technical, commercial and economic viability of a German manufacturing base for high-temperature superconducting wire, with a possible production site in Lower Saxony at the centre of the review. Proxima describes the project as a joint study of industrial-scale manufacturing — a feasibility check, not a confirmed factory investment.
The memorandum was signed in Tokyo during German leader Merz's visit to Japan. Decisions on financing, production capacity and construction timelines are all still outstanding. Neither a plant order nor a binding supply commitment has been agreed, so the arrangement amounts to a possible supply chain rather than a done deal. What matters for valuation is whether the review eventually yields firm production and delivery pledges.
Should investors sell immediately? Or is it worth buying Fujikura?
Fujikura is no newcomer to the field: it has worked on high-temperature superconducting wire for more than 30 years, so the study extends an existing technological base rather than marking a fresh entry.
Demand Forecasts Are Not Orders
Proxima estimates that its Alpha demonstrator will need roughly 20,000 kilometres of superconducting tape, and it puts demand at about 40,000 kilometres for each planned Stellaris power plant. Those figures are projections, not orders placed with Fujikura — they hint at the scale of a future supply relationship without saying anything about secured revenue.
The timeline is long. Alpha is meant to produce net energy in the early 2030s, with the first commercial Stellaris plant slated for later in that decade, tying any eventual demand to the fusion developer's long-range goals.
An earlier Lower Saxony development concept proposed investments of around EUR 140 million for the first two phases, with a planned state contribution of EUR 21 million. Neither sum represents a confirmed investment commitment from Fujikura, and the regional plan should not be conflated with the new feasibility review into a single financed factory project.

Local Matters and a Typhoon Donation
On other corporate matters, Fujikura said part of its Sakura site has been designated an area requiring action, and that it intends to respond. The company also announced on 19 October a donation of JPY 20 million for those affected by Typhoon No. 25, as well as for restoration and reconstruction efforts.
For investors, the takeaway is an industrial prospect rather than an earnings driver: Fujikura is exploring European manufacturing with a potential customer, but no reliable financial contribution can be derived from it yet. Binding decisions on production, funding or supply would mark the next substantive step.
