Layer 3 · 005930 — Samsung Electronics
Thesis
Record Q1 — memory profit +48x YoY, OP exceeded full-year 2025 in a single quarter, FY26 record. Tier B not Tier A because the HBM4 NVIDIA qualification is the gating issue — Samsung still hasn't cleared NVDA HBM3E qual, the share gap to SK Hynix persists, and the -8.6% single-day drop on May 15 signals the positioning unwind has begun.
What it does + financial print
Samsung is the conglomerate — memory (DRAM, NAND, HBM), foundry (3nm, 2nm in ramp), mobile (Galaxy), display, consumer electronics. The AI thesis runs almost entirely through memory and foundry. Memory is exceptional. Foundry has been losing money. NVDA HBM3E qualification has been pending for ~18 months and is the single binary catalyst for this stock.
Q1 2026 (April 30) printed KRW 133.9T revenue (+69% YoY) — record. OP KRW 57.2T — record, 8x+ YoY. Memory profit +48x YoY. HBM revenue to 3x in 2026 vs 2025. HBM4E samples Q2. Foundry still drag. Stock -8.6% on May 15 to KRW 270,500 after touching ATH KRW 299,500 on May 14.
Bull case
NVDA finally qualifies Samsung HBM3E (and/or HBM4) for volume — that one event closes the share gap with SK Hynix, expands Samsung's revenue, and triggers a multi-quarter re-rate. Foundry 2nm stabilises with one named external customer (Tesla rumour, Google rumour). The conglomerate trades at a sum-of-parts discount that closes.
Gap / bear case
The qualification has been "imminent" for 18 months and hasn't happened. Every quarter it doesn't happen is another quarter of SK Hynix locking in NVDA Rubin allocations. Foundry losses continue. Mobile is structurally slowing. Labour-strike rumours add execution noise.
Trigger to upgrade / downgrade
Upgrade to Tier A on NVDA HBM3E / HBM4 qualification announcement with volume commitment. Downgrade on a public NVDA decision to single-source SK Hynix on HBM4.
