Company snapshot — Comet Holding AG

COTN.SW in five paragraphs: what it makes and sells, where it sits in the Closelook stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
Comet Holding makes radio-frequency power components and X-ray inspection systems, split across three divisions. Plasma Control Technologies builds vacuum capacitors, RF generators and matching networks that keep plasma processes stable during chip and flat-panel-display production. X-Ray Systems and Industrial X-Ray Modules make compact X-ray sources and computed-tomography equipment for non-destructive testing, steel metrology and security screening, sold under the Comet and Comet Yxlon brands. It is based in Flamatt, Switzerland, and serves semiconductor, aerospace, automotive and security manufacturers.
Where it sits in the stack
In our index, Comet sits in Layer 2, Fabrication — the stage where wafers are deposited, etched and inspected — within the Deposition, Etch & Process sleeve, the process-equipment kit every fab orders. Comet does not build the etch or deposition tool itself; it supplies the RF power and plasma-control parts that the sleeve's larger tool makers depend on to hold process precision.
Who it is priced against
Closelook's peer group for this sleeve covers process-equipment vendors for deposition, etch, CMP and clean, and places Comet alongside ASM International, Lam Research, Applied Materials, Inficon, VAT Group, AIXTRON, Kokusai Electric and Tokyo Electron.
Why Closelook tracks it
Comet holds a seat in our Rubin Build-Out 100 and in the Euro-AI 50. It carries a Closelook score, where the balance-sheet module reads strongest and valuation weakest among its seven modules; the diary has not yet quoted it in an edition.
What the diary watches
Whether orders for RF and plasma-control components pick up as fabs place fresh orders for etch and deposition tools, since Comet's volumes move with that upstream tool-buying cycle rather than with chip demand directly.

Comet Holding AG (COTN.SW) trades on the SW exchange in Switzerland, classified under Technology, and sits in Layer 2 of the build-out stack. Constituent of Rubin Build-Out 100 and Euro-AI 50.

The Closelook company score reads 43/100 composite (momentum 51, quality 27, valuation 23) across 7 modules — the full breakdown, chart structure and analog history load live above.
