Asked whether AI-server MLCC could collapse into single-sourcing, we laid out the oligopoly from our #3 seat: high performance requirements limit qualified suppliers, but heavy production load makes single sourcing unrealistic, so the multi-sourcing model holds. That is the shape — a tight oligopoly, not a winner-take-all monopoly. Our distinctive edge is embedded MLCC: capacitors buried in the package substrate next to the die, with two families in mass production for AI-server IC power lines — a 1005/0402 22μF part from August 2025 and a 2012/0805 100μF part from November 2025.

I'm the world's #3 maker of multilayer ceramic capacitors, behind Murata at #1 and Samsung Electro-Mechanics at #2 - a genuine member of the oligopoly, not a fringe name, and materials-up full-stack the same way the leader is, at about one-fifth the scale. Capacitors are 71% of my revenue - ¥251.8bn, up 8.5% - far more concentrated than Murata's 51%, so I ride the cycle harder both ways. My operating profit nearly doubled to ¥20.0bn, up 91%, but that came off a depressed 3.1% margin base; it's almost entirely a capacity-utilization recovery, and my margin is still just 5.6% against the leader's ~15%. I missed every economic target of my last five-year plan and re-filed the same ones in Plan 2030, pushed out five years. The AI-server MLCC ramp is mostly still ahead of me - significant change expected from the second half of this year, more volume next year onward - and I don't break out a data-center revenue line to prove it.

We are the world’s #3 maker of multilayer ceramic capacitors, behind Murata at #1 and Samsung Electro‑Mechanics at #2 – a genuine member of the oligopoly rather than a fringe name. We run a full‑stack chain from materials to mass production, the same vertical model as the leader but at about one‑fifth the scale. Our balance sheet is ordinary, with an equity ratio of 56% versus Murata’s 85%, and we raised ¥97 bn of external funds across the five years to 2025 because operating cash flow did not cover capex through the trough.
We see the AI-server MLCC landscape as a tight oligopoly, not a winner-take-all monopoly. High performance bars limit qualified suppliers, yet production load keeps multi-sourcing realistic — the model isn't expected to fundamentally change. Our embedded-MLCC edge: two families in mass production for AI-server IC power lines — a 1005/0402 22μF part from August 2025 and a 2012/0805 100μF part from November 2025.
I am the world's #3 MLCC maker, behind Murata and Samsung Electro-Mechanics — a genuine oligopoly member, not a fringe name. Full-stack from materials to mass production, the same vertical model as the leader at one-fifth the scale. The honest verdict: I hold a real seat as the junior member — lower-margin, more cyclical, equity ratio 56% vs Murata's 85%. I raised ¥97bn externally over five years to 2025 because operating cash flow didn't cover capex through the trough.
An AI server already uses 10,000 to 20,000 MLCCs, expected to more than double by 2030. Our model shows AI-server MLCC demand growing at a +32% CAGR to 2030 against unit growth of only +5% — the gap is content per box, not box count. Power inductors at +18%. The pull is toward smaller, higher-capacity parts on motherboards to cut power loss. Unlike Murata, we disclose no AI-server or data-center revenue split; our capacitor guide for the year ending March 2027 is an aggregate +12% to ¥282.0bn, with AI servers and autos named as drivers but not quantified.
For the year ended March 2026, our capacitors were ¥251.8bn, up 8.5%, and 71% of revenue — far more concentrated than Murata's 51%, making this the purest MLCC-cycle exposure in the group. The AI-server story is one slice of a recovering electronics maker; integrated modules fell 35.6% as circuit-module lines wound down, and communication devices target break-even next fiscal year after a multi-year slide. With a 5.6% operating margin, the cyclical-recovery character dominates more here than at the leader.
For the year ended March 2026, net sales ¥355.3bn (+4.1%), operating profit ¥20.0bn (+91% YoY). The jump came off a 3.1% margin trough — almost entirely utilization recovery, not re-rate. Bridge: ¥30.7bn utilization gain offset by ¥20.2bn price decline; prices still fall, just slower. Operating margin 5.6% vs leader's ~15%. Net profit flattered by ¥4.8bn FX gain, dented by ¥2.1bn aluminum-electrolytic impairment and ¥1.5bn communication-device reform loss — the operating line is the one to read.
Industry-wide price increases? No signs yet — prices still falling, a ¥20.2bn selling-price drag in our bridge. We negotiate only selective pass-through on silver and precious-metal cost pressure, a high-single-digit-billion-yen risk on inductors and some MLCCs, and will not raise above raw-material moves. The pricing kernel sits in the top bin: large-sized MLCCs for AI servers and automotive keep a stable-price outlook, more customers locking annual contracts. Capacity rose ~5% in the year ended March 2026, stepping to ~10% next year; back-end lead time ~6 months means supply answers fast.
