The largest customer relationship — supplies dry-strip (PR removal) and dry-clean tools to Samsung, whose memory/foundry capacity cycle sets the amplitude of PSK's earnings. - SK hynix High confidence
Supplies dry-strip tools to SK hynix — HBM/DDR5 expansion adds process steps that lift strip-tool demand, a core growth axis. - Intel Medium confidence
Supplies dry-strip tools to Intel — revenue tied to Intel's foundry/logic capacity investment; as a mandatory single-step tool, a restart in Intel capex flows straight into demand.
Pays to
- components & modules (undisclosed) Low confidence
Outsources parts and modules for its tools (suppliers undisclosed) — as a tool integrator, component supply stability drives lead times and cost. - precision machining & metrology (undisclosed) Low confidence
Buys precision-machining and metrology modules (undisclosed) — key inputs that determine plasma-process precision, with dependence rising as specs tighten.

YTD as of 2026-07-10 · source: Yahoo Finance
The core of PSK is a narrow but essential bottleneck position — global No.1 in dry strip (photoresist removal). Strip is a mandatory front-end step, so its results track the capacity and scaling investment of customers (Samsung, SK hynix, Intel) directly, and as HBM/DDR5 stacking adds process steps, tool demand grows structurally. The next growth lever is entering adjacent steps via dry clean and a new metal-etch product to widen revenue-per-tool and TAM, with reducing single-process dependence the key. In graph terms PSK is a revenue node to a few large customers (Samsung, SK hynix, Intel) with high concentration, so their capex cycle sets the amplitude of its earnings.
