CIS (KOSDAQ: 222080): Battery Electrode & Solid-State Assembly Equipment
The electrode-equipment maker that shows up on both ends of the solid-state chain — supplying the tools and, increasingly, the materials pilot lines too.
Who they are
CIS (씨아이에스) is a battery electrode-process equipment maker under the SFA group umbrella, and one of the more unusual names in this chain because it plays two roles at once: equipment supplier and materials developer. It absorbed CI Solid, a solid electrolyte-focused affiliate, in an earlier merger, and completed a further absorption of display/semiconductor inspection equipment maker SNU Precision to diversify its portfolio beyond battery-only cyclicality.
What they do
CIS's core products are the machines that turn battery materials into finished electrodes — mixing, coating, roll-pressing, and cutting equipment used in the first stage of lithium-ion cell manufacturing, sold to major cell makers like LG Energy Solution and Samsung SDI. On top of that legacy business, CIS has built a solid electrolyte pilot production line with a continuous manufacturing system, developed a "hybrid coater" for next-generation electrode drying, and signed NDAs with a European automaker and a North American energy company to explore supplying both solid electrolyte materials and the equipment to process them.
How they make money
CIS sells electrode-process equipment on long lead-time contracts — the company itself notes that orders typically take about two years from order to delivery, which meant 2022–2023 orders placed before the EV demand slowdown helped cushion its 2024–2025 results even as the broader capex cycle cooled. FY2025 revenue came in at ₩508.5 billion with ₩59.3 billion in operating profit, and the company entered 2026 with roughly ₩750 billion in order backlog — more than double the prior year's revenue, a sign that customer capex is still flowing even in a soft macro environment.
Where it sits in the value chain
CIS is unusual in this chain for legitimately spanning two stages: Solid Electrolyte Materials, through its own pilot electrolyte production line and NDAs to supply the material directly, and Manufacturing Equipment, through its core electrode-process machinery business. Most companies in this chain sit cleanly in one tier — CIS's dual role reflects how it absorbed a materials-focused affiliate (CI Solid) rather than building the electrolyte business from scratch.
The bigger trend
CIS's stock has moved on solid-state headlines more than once — jumping over 15% in a single session on news of a North American energy-company NDA for solid electrolyte materials and equipment, and separately rallying on reports that Samsung SDI had effectively finished ASSB development and was preparing for delivery. Those are exactly the kind of story-driven moves worth treating with some skepticism: an NDA is a confidentiality agreement, not a supply contract, and "preparing for delivery" reports about a customer aren't the same as CIS itself landing a named order. The SNU Precision merger, completed at the end of 2025, is the more concrete signal — a deliberate diversification away from pure battery-equipment cyclicality into display and semiconductor inspection tools.
What to watch
- Whether either the European-automaker or North American-energy-company NDA converts into a named solid electrolyte or equipment supply agreement.
- Whether CIS's ₩750 billion order backlog actually converts to shipped revenue on schedule, given the roughly two-year order-to-delivery lag the company itself has cited.
- How the SNU Precision integration affects CIS's exposure to battery-specific demand cycles going forward.

FAQ
Is CIS a materials company or an equipment company?
Both. Its core, longest-running business is electrode-process equipment (mixing, coating, roll-pressing, and cutting machines) for lithium-ion cell makers. It also runs a solid electrolyte pilot production line, inherited through its earlier absorption of affiliate CI Solid, which puts it in the Solid Electrolyte Materials tier as well.
Does CIS have a confirmed solid-state battery supply deal?
Not publicly, as of mid-2026. It has signed NDAs — non-disclosure agreements for exploratory discussions — with a European automaker and a North American energy company covering solid electrolyte materials and equipment, but neither has been confirmed as a named commercial supply contract.
Why did CIS merge with SNU Precision?
SNU Precision makes display and semiconductor inspection and measurement equipment. The absorption, completed at the end of 2025, diversifies CIS's revenue base beyond battery-equipment cycles, which are tied closely to EV demand swings.
