Samsung Electronics has warned that a worsening global chip shortage is likely to persist this year and beyond, as the explosive build-out of artificial intelligence infrastructure continues to absorb vast amounts of memory supply, reinforcing the company’s dominance in semiconductors while creating growing strains across its broader electronics empire.
The South Korean tech giant said on Thursday that operating profit more than tripled in the fourth quarter to a record level, driven overwhelmingly by soaring memory chip prices and demand linked to AI servers and data centers. Yet the same forces lifting profits are also raising costs for Samsung’s smartphone and display units, sharpening internal trade-offs that underline how uneven the AI-driven cycle has become.
Samsung posted an operating profit of 20 trillion won ($13.98 billion) for the October-to-December period, up sharply from 6.49 trillion won a year earlier and in line with its own guidance. Quarterly revenue climbed 24% to 93.8 trillion won, reflecting both higher prices and stronger shipments across parts of the business.
At the core of the performance was the chip division, Samsung’s main profit engine. Operating profit in semiconductors surged 470% year-on-year to a record 16.4 trillion won, accounting for more than 80% of the group’s total earnings. The results underscored Samsung’s pricing power as the world’s largest memory chipmaker at a time when supply is struggling to keep pace with AI-led demand.
Executives made clear that relief is not imminent. “A significant shortage of memory products across the board is expected to continue for the time being,” Kim Jaejune, an executive in Samsung’s memory business, told analysts on the post-earnings call.
He said any meaningful expansion of supply was likely to be constrained through 2026 and 2027, even as AI-related demand continues to surge.
That warning rattled investors. Samsung shares slipped 1.2% on Thursday, giving back some gains after a strong rally earlier this year, as markets digested the implications for the company’s non-chip businesses.
While higher memory prices are a boon for semiconductors, they are becoming a clear headwind for Samsung’s mobile and display units, which rely heavily on in-house chips. Operating profit in the mobile division fell 10% to 1.9 trillion won in the quarter, squeezed by rising component costs in an intensely competitive global smartphone market.
“Memory price increases are expected to accelerate this quarter and are likely to give surprise earnings, while the memory cost burden will intensify on its mobile business,” Reuters quoted Sohn In-joon, an analyst at Heungkuk Securities, as saying.
He expects Samsung’s overall profit to surge roughly fivefold in the current quarter to around 35 trillion won from a year earlier, largely on the back of chips.
Executives at Samsung’s device businesses struck a cautious tone, according to Reuters. The mobile and display divisions both described the outlook for the year as challenging, citing cost pressures and the risk of weakening demand if prices rise too sharply.
Cho Seung, a senior executive in the mobile division, said Samsung would work closely with major partners to ensure a stable supply while pushing internal efficiencies to limit margin erosion. Still, the pressure is evident. Samsung co-CEO TM Roh described the current shortage as “unprecedented” in an interview with Reuters and did not rule out price increases, a move that could test consumer demand further.
“How the division defends margins as the year progresses will be a key issue,” said Ko Yeongmin, an analyst at Daol Investment & Securities, pointing to the delicate balance between maintaining volumes and protecting profitability.
The display business faces similar strains. Although display operating profit more than doubled to 2 trillion won in the fourth quarter on strong sales tied to Apple’s iPhone 17 series, executives warned that smartphone demand could soften in the current quarter as higher memory costs ripple through the supply chain. Customers, they said, are likely to push harder for price cuts.
Much of the tension across Samsung’s businesses stems from the industry-wide shift toward AI-focused hardware. Chipmakers have diverted manufacturing capacity toward high-bandwidth memory, or HBM, which is essential for AI accelerators used by companies like Nvidia. That has tightened the supply of conventional memory products used in smartphones, PCs, and other consumer devices.
Samsung said it has already begun producing its next-generation HBM4 chips and plans to ship them in February at the request of a “major customer,” widely understood to be Nvidia. Customers are currently completing qualification tests, and Samsung expects overall HBM revenue to more than triple this year after securing orders for all of its available HBM capacity.
The company has been racing to close the gap with domestic rival SK Hynix, which has emerged as Nvidia’s primary supplier of advanced HBM and enjoyed a first-mover advantage after Samsung faced supply delays last year. SK Hynix said this week that large-scale production of its next-generation HBM is underway and played down rising competition, pledging to defend its dominant market share.
For now, the imbalance between demand and supply leaves memory makers firmly in control.
“They’re in the enviable position of being able to dictate price, terms, etc more than ever,” said Tobey Gonnerman, president of semiconductor distributor Fusion Worldwide. “There is ample robust demand, and they can’t possibly fill it all.”
