Nikkei 225 · Optical & wire (AI-data-center cabling)
Fujikura
One of three makers (with Sumitomo Electric and Furukawa) that oligopolize the high-end high-density optical-cable market, Fujikura has become a 'seller of shovels' as AI data centers' demand for GPU-cluster cabling (SWR, WTC) and fusion splicers outruns supply. In FY ended Mar 2026 its Information & Communication unit alone produced JPY 653.0bn of sales (+44.7%) and 80%+ of group OP, lifting net profit to a record JPY 157.2bn (+72.5%) — which, inverted, means earnings are hostage to a single cycle. With demand above capacity and prices rising, the JPY 530bn mid-term plan to triple capacity is a bet placed at the front of this supercycle.

Financials & Segments
- Total revenue · Sales JPY 1,182.4bn (+20.7%), OP JPY 188.7bn (+39.2%), net profit JPY 157.2bn (+72.5%, record) — almost all of the profit gain came from one segment (FY ended Mar 2026)
- Customer concentration · A 'single growth engine' structure — Information & Communication (fiber/cable) is 80%+ of group OP, which is both the strength (pure leverage to the AI-capex supercycle) and the weakness (earnings hostage to one cycle). On a three-way oligopoly with Sumitomo Electric and Furukawa, and with demand exceeding capacity, the JPY 530bn mid-term plan triples Japan/US capacity to target JPY 1.6tn revenue and JPY 315bn OP by FY2028.

- Hyperscalers / AI data centers (optical cabling) — customers unnamed High confidence· net sales 653 JPY_bn · FY ended Mar2026
As AI data centers scale GPU clusters, demand for server/rack optical cabling (SWR, WTC) and fusion splicers compounds — so the Information & Communication unit alone generated FY2026 OP of JPY 152.7bn (+65.7%), over 80% of group OP. The point is that demand outran capacity and Fujikura is raising prices: this is the early, supplier-favored phase of the cycle where everything it can make, it sells. The CEO says Fujikura takes orders from 'almost all US hyperscalers' but named no client, so individual counterparties stay anonymous.Mentions EN MarketScreener (12-analyst consensus) Published Jul 1, 2026: Fujikura (5803) analyst consensus — Strong Buy, target priceConfirms KO Alphabiz (KR) Published May 20, 2026: Fujikura to invest up to JPY 260bn in fiber capacity; AI data center mid-term planConfirms JA Fujikura (TDnet financial results) Published May 14, 2026: Fujikura FY ended Mar 2026 Financial Results (Japanese GAAP, consolidated) - Apple (smartphone FPC / electronic components) Medium confidence· operating income 7.7 JPY_bn · FY ended Mar2026
As a world top-5 FPC maker, Fujikura has supplied flexible printed circuits for iPhones (e.g., iPhone 12 Pro/Max) — but with its center of gravity shifting to optical cable, this is a shrinking legacy exposure. FY2026 Electronics OP was squeezed to JPY 7.7bn (-66.5%) by competition and a strong Thai baht, evidence that Apple-facing FPC no longer drives earnings and now partly offsets the Info & Comm boom.Confirms JA Fujikura (TDnet financial results) Published May 14, 2026: Fujikura FY ended Mar 2026 Financial Results (Japanese GAAP, consolidated) - NTT (Japan telecom infrastructure, optical fiber) Medium confidence
A traditional optical-fiber/cable supplier and co-development partner for Japan's telecom backbone — with NTT and Hokkaido University it realized a >100-channel ultra-high-density fiber within a <250µm glass diameter. This domestic reference matters less for its own revenue than for what it proved: Fujikura's credibility in 'density' — the very qualification that now underwrites its hyperscaler high-density cable wins.Confirms JA Fujikura (TDnet financial results) Published May 14, 2026: Fujikura FY ended Mar 2026 Financial Results (Japanese GAAP, consolidated)Confirms EN NTT Published May 16, 2016: NTT, Fujikura & Hokkaido Univ. — world's highest-density optical fiber

- Copper & aluminum (wire, harness, power cable) High confidence
Copper and aluminum anchor the cost of auto wire harnesses and power cables — and are where the same input cuts opposite ways by segment: Automotive absorbs copper spikes with lagging pass-through (OP JPY 6.8bn), while Energy books copper-derivative valuation gains and grew (+58.6%). Because hedging and pass-through ability decide segment profit, copper is not a pure negative for Fujikura but a question of segment mix.Confirms JA Fujikura (TDnet financial results) Published May 14, 2026: Fujikura FY ended Mar 2026 Financial Results (Japanese GAAP, consolidated) - Optical-fiber preform materials & hydrogen (silica, GeCl4) Medium confidence
An optical fiber begins with a preform made from high-purity silica and germanium tetrachloride plus large volumes of burned hydrogen — so the real bottleneck to expansion is materials, not tools. The filing's own warning that 'a steep ramp in optical cable could constrain procurement of some raw materials such as hydrogen' is the crux: the execution risk of the 3x-capacity plan sits in this upstream materials chain.Confirms JA Fujikura (TDnet financial results) Published May 14, 2026: Fujikura FY ended Mar 2026 Financial Results (Japanese GAAP, consolidated)

- AI optical-cabling capacity & growth investment (mid-term plan FY26-28) High confidence· Amount 530 JPY_bn · mid term FY26 28
On the judgment that demand outstrips capacity, the FY26-28 plan deploys ~JPY 530bn (up to JPY 300bn for cable) to triple Japan/US capacity — a pre-emptive, demand-securing capital bet. It underwrites the FY2028 targets of JPY 1.6tn revenue and JPY 315bn OP and is double-edged: if the supercycle holds it locks in share and pricing, but if it breaks the 3x capacity becomes overbuild. What actually paces this expansion is the hydrogen/materials chain above.Confirms JA Fujikura (TDnet financial results) Published May 14, 2026: Fujikura FY ended Mar 2026 Financial Results (Japanese GAAP, consolidated)

The thesis is single-axis leverage — one segment (Information & Communication) drives 80%+ of group OP and pushed net profit to a record JPY 157.2bn, and the stock rose +425% in 2024 and +217% in 2025 as a flagship AI-data-center name. The engine is a three-way oligopoly with Sumitomo Electric and Furukawa where demand exceeds capacity and pricing power has shifted to suppliers — which is why a JPY 530bn, 3x-capacity build makes sense. The risk is symmetric: Electronics (-66.5%) and Automotive are structurally weak with no cyclical buffer, and if the supercycle breaks the tripled capacity becomes overbuild. In the graph, the ripple runs from Nvidia/hyperscaler AI capex → optical interconnect → Fujikura (parallel to Corning), while the execution bottleneck sits upstream in preform materials (silica, hydrogen).
