Samsung Electronics (005930.KS)

Samsung's revenue splits roughly between Device Solutions—memory chips (DRAM, NAND), foundry manufacturing, and System LSI—and DX, the consumer-facing division behind Galaxy smartphones, TVs, and home appliances; memory has historically been the more volatile half, swinging from record profits to losses within the same product line depending on where the chip cycle sits. The 2024-2025 AI boom pushed demand for high-bandwidth memory (HBM) used in AI accelerators, a product where Samsung competes directly with SK Hynix and Micron for the same customers, including NVIDIA (see our NVIDIA page).

In foundry manufacturing, Samsung trails TSMC in advanced-node market share and yield, which caps how much of the AI chip boom's contract-manufacturing revenue flows to Samsung versus its Taiwanese rival even in years when Samsung's own memory business is thriving. In smartphones, Samsung's Galaxy line competes with Apple at the premium end and with Chinese brands like Xiaomi in mid-range volume, a squeeze from both directions that limits pricing power despite Samsung shipping more units globally than any single competitor.

Samsung Electronics is the flagship of the Samsung Group conglomerate (Samsung Life, Samsung SDI, and others), controlled through cross-shareholdings by the Lee family, currently led by Chairman Lee Jae-yong; this governance structure means the revenue reported here flows through a company whose strategic decisions are shaped as much by group-level succession and control questions as by pure market economics. Reported revenue, converted from Korean won, is also a poor proxy for profit given how sharply memory-chip margins compress during industry downcycles even as unit revenue holds up.

Samsung's fiscal year runs the calendar year, and this counter spreads that annual total evenly across seconds, which flattens what is in reality one of the most cyclical revenue lines among major technology companies—memory pricing alone can swing 30-40% year over year. Samsung's own quarterly earnings guidance and Device Solutions-division commentary are the primary source for tracking where in that cycle the business currently sits, far more useful than a flat annual figure.
