Company snapshot — Samsung Electronics Co Ltd

005930.KS 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
Samsung Electronics spans consumer electronics, mobile devices and semiconductor manufacturing, organised into divisions covering finished devices, chip production, displays and the Harman audio business. It sells smartphones, tablets, televisions, appliances and displays, alongside memory chips, storage and foundry services that fabricate chips designed by outside customers. Its semiconductor arm makes memory — DRAM, NAND and high-bandwidth memory — and also runs a logic foundry for external chip designers. It is based in Suwon-si, South Korea.
Where it sits in the stack
In our Rubin Build-Out 100 index, Samsung sits in Layer 3, Assembly & Test, within the HBM Memory sleeve — the sleeve Closelook uses to track high-bandwidth memory, the part of the AI compute stack where supply has run short. Samsung is a producer inside that constraint, making HBM alongside conventional DRAM and NAND, and competing for qualification into the AI accelerators built by designers further up the chain.
Who it is priced against
Closelook's peer group here is curated as foundries: Taiwan Semiconductor Manufacturing, Intel, Globalfoundries and United Microelectronics. On the memory side the market more commonly prices Samsung against SK Hynix.
Why Closelook tracks it
Samsung is a constituent of the Rubin Build-Out 100 and carries a Closelook score, strongest in valuation and weakest in momentum. It appears in the diary's 101 format on HBM economics alongside SK Hynix and Micron, and in the Morning 10 during sessions when Korean chipmakers sell off sharply.
What the diary watches
The diary watches whether Samsung narrows the qualification gap with SK Hynix on advanced HBM generations sought by AI accelerator customers.
