Samsung Electronics (Korea)
Summary
What they do:
Manufacture DRAM, NAND flash, HBM, and operate a semiconductor foundry — the world's largest memory producer by total capacity and the only company that is both a major HBM supplier and a custom chipmaker — sitting at Layer 08 as the #2 HBM producer recovering from qualification setbacks to become a leading HBM4 supplier for NVIDIA's Vera Rubin platform.
Why they matter:
Samsung is the world's largest memory manufacturer and the only company that combines HBM memory production, foundry services, and advanced packaging under one roof. After its HBM market share collapsed from 41% to 17% due to NVIDIA qualification failures, Samsung has recovered to ~33% and has been tapped as a lead HBM4 supplier for Vera Rubin — the comeback story of the memory supercycle.
Recent performance:
Q1 2026 preliminary results: revenue KRW 133T, operating profit KRW 57.2T (record, ~50% above consensus). Memory operating profit alone expected to exceed KRW 40T. HBM revenue tripled YoY. Stock at ~₩202,500, market cap ~$974B. Began world's first HBM4 mass production for NVIDIA Vera Rubin in February 2026.
Our Verdict
The HBM recovery play — share collapse from 41% to 17% after qualification failures was the buying opportunity, and recovery to 33% with HBM4 lead supplier status for Vera Rubin is the catalyst — but conglomerate structure dilutes the AI thesis relative to SK Hynix.

Samsung Electronics is a conglomerate that spans semiconductors, displays, smartphones, and consumer appliances. Within the AI infrastructure thesis, what matters is the semiconductor division — specifically the memory business (DRAM, NAND, HBM) and secondarily the foundry business (custom chip fabrication competing with TSMC).
Samsung operates the world's largest memory fab footprint across Hwaseong, Giheung, and Pyeongtaek in South Korea, employing 100,000+ people in semiconductors alone. The scale is staggering: Samsung's semiconductor division generates over $150B+ in annual revenue, more than any US chipmaker. The company is vertically integrated — controlling fab capacity, process technology, advanced packaging, and product lines under one roof.
The HBM recovery story is the AI thesis. Samsung's HBM market share collapsed from 41% to 17% after failing NVIDIA's HBM3E qualification tests — a devastating setback that proved capital alone doesn't guarantee HBM success. Since then, Samsung has recovered: HBM3E was eventually qualified, market share recovered to ~33%, and — critically — Samsung began the world's first HBM4 mass production for NVIDIA's Vera Rubin platform in February 2026. Reports indicate Samsung has been tapped alongside SK Hynix as an exclusive HBM4 supplier for Vera Rubin, with Samsung reportedly leading Vera Rubin-specific HBM4 allocation.
Q1 2026 preliminary results were extraordinary: revenue KRW 133T with operating profit KRW 57.2T — a record, 50% above consensus. Memory alone is expected to generate over KRW 40T in operating profit. HBM revenue tripled YoY. DRAM prices have surged ~10x. Samsung plans a 50% HBM capacity surge in 2026.
The foundry business is a different story. Samsung's foundry competes with TSMC at advanced nodes (3nm GAA, 2nm) but has consistently lost share — NVIDIA and Qualcomm both moved to TSMC. The Taylor, Texas fab (opening 2027) is Samsung's play for US-based production. The foundry is AI-relevant but structurally disadvantaged versus TSMC.

The Catch
Samsung is a conglomerate where the AI memory thesis lives in one division. The memory business is delivering record results — HBM revenue tripling, DRAM prices up 10x, KRW 40T+ in memory operating profit. But Samsung also operates a foundry that is structurally disadvantaged versus TSMC, a consumer electronics business that cycles with the global economy, and a display business that faces OLED competition. Investors cannot buy just the memory division. The conglomerate structure means HBM's record profits can be partially offset by foundry losses, and the stock will always trade at a discount to SK Hynix because the AI narrative is diluted. Additionally, Samsung's HBM qualification failure in 2025 — losing share from 41% to 17% — is a cautionary tale about execution risk. The HBM4 recovery is real, but one bad qualification cycle erased years of market position. It can happen again.
If They Win
If Samsung's HBM4 yields match SK Hynix's — if the Vera Rubin supply win marks the beginning of a sustained competitive recovery — and the foundry business stabilizes with 2nm GAA wins for AI ASICs, Samsung becomes the most vertically integrated AI infrastructure company in the world. The only company that can produce HBM memory, fabricate AI logic chips, and package them together. HBM market share reaches 40%. Memory revenue exceeds $100B. Foundry breaks even on AI ASIC wins. The integrated offering (memory + logic + packaging) attracts customers who want a single-vendor AI chip solution. Market cap exceeds $1.5T. Samsung's conglomerate discount flips to an integration premium — the TSMC of memory, the SK Hynix of foundry, all under one roof.
