Samsung Electronics is on track to post quarterly operating profit above 100 trillion won, about $74 billion, for the first time in its history, with DRAM margins expected to exceed 80 percent. Estimates from DB Securities, Mirae Asset Securities and BNK Securities put third-quarter operating profit at an average of 107.7 trillion won, up 20.3 percent from 89.4 trillion won in the second quarter, according to industry sources cited by The Korea Herald.
The numbers reflect a memory market that has been repricing for most of the year. Three brokerages expect the operating margin of Samsung’s Device Solutions division, which houses the semiconductor business, to reach 72 to 75 percent, with DRAM margins above 80 percent once high-bandwidth memory and conventional chips are counted together. For a division that spent long stretches of the last decade barely breaking even during downturns, the swing is one of the sharpest in the company’s history, and it has reset expectations for what the memory business can earn at its peak.
Prices cooling, margins not
Market research firm TrendForce expects DRAM prices to rise 13 to 18 percent on-quarter in the third quarter. That is a sharp slowdown from the roughly 60 percent increase recorded in the previous quarter, but the deceleration is not cutting into profitability yet. Margins have kept expanding because the price gains arrived on top of a product mix that has shifted toward the most expensive chips the industry makes.
Analysts attribute the unusually strong margins to how memory makers are allocating capacity. As Samsung and its rivals devote more advanced DRAM production to HBM and high-capacity server products, less capacity remains for conventional DRAM. Demand for server DDR5 is also rising alongside investment in AI data centers, so the constrained conventional segment is seeing price increases of its own. The result is a market where even the commodity end of the product line sells at a premium, and where spot prices have decoupled from the long-run cost curves that used to anchor them.
Supply squeeze stretches lead times
The shortage is showing up in delivery schedules. Kim Dong-won, head of research at KB Securities, expects HBM to account for 40 percent of Samsung’s total DRAM capacity next year, up from 33 percent this year, while the conventional DRAM share falls from 65 percent to 59 percent. Lead times for high-capacity server DDR5 have stretched to as long as 52 weeks this month, compared with around six weeks under normal market conditions.
Kim expects the shift to persist. A structural reallocation of production capacity toward HBM prolongs shortages of conventional DRAM and pushes prices higher, he said, describing a market where the constraint is deliberate rather than accidental. Memory makers have little incentive to redirect capacity back to commodity chips while HBM contracts command better returns and are often signed years in advance with hyperscale customers.
The wafer and raw material markets are moving the same direction. MoneyToday reported this week that prices are rising across the semiconductor supply chain, from raw materials through wafers to finished chips, a pattern that suggests the shortage is feeding through the whole production chain rather than sitting in one layer. Upstream suppliers are passing their own cost increases along, which compounds the pressure on anyone buying components.
What it means for buyers
For data center operators and device makers, the 52-week lead times translate into higher component costs and harder planning. PC and smartphone makers have already begun passing memory costs through in some segments, and the supply chain price increases reported this week suggest the pressure is not limited to finished DRAM. The cost of a memory upgrade has become one of the more visible ways AI infrastructure spending reaches consumers, showing up in laptop configurators and phone storage tiers months after the data center contracts that caused it.
Competitors are in similar positions. SK Hynix and Micron have both prioritized HBM output, and none of the three has signaled a meaningful return of capacity to conventional DRAM before next year. That leaves buyers with limited leverage until new capacity, which takes years to build and qualify, comes online. Some server customers have responded by locking in long-term supply agreements at fixed prices, effectively paying a premium now for certainty later.
Records with an asterisk
A 107.7 trillion won quarter would put Samsung’s profit at a level few industrial companies anywhere have reached, driven by a single division. The caveat is cyclicality. Memory markets have historically swung from shortage to glut within roughly two years, and the current cycle has run hot for several quarters. Brokerages are already modeling what happens when HBM supply catches up with demand, and the conventional DRAM share, now squeezed for margins, is the first place that shows up in a downturn.
The other risk is substitution. Sustained high DDR5 prices give cloud operators an incentive to design workloads around existing memory or delay refresh cycles, which would hit demand from the same AI buildout that is driving the boom. Nobody is forecasting that yet, but memory demand has a way of pausing just as supply arrives.
For now, the numbers point one way. Samsung reports full third-quarter results later this month, and the brokerages’ consensus implies the record is a formality. The question worth watching is not whether the quarter lands above 100 trillion won, but what management says about 2027 capacity plans, since that is where the cycle turns first.
