SK Hynix reported a five-fold jump in quarterly profit to a record $25.4 billion, driven by soaring memory prices and surging demand for high-bandwidth memory chips used in AI data centers. The Nvidia supplier plans significant capital spending increases to expand production capacity, while executives highlight a structural shift in the memory sector that could extend the upcycle through 2028.

SK Hynix Achieves Record Quarterly Profit Amid AI Boom

SK Hynix delivered a stunning performance in the first quarter, posting operating profit of 37.6 trillion won ($25.4 billion), a five-fold increase from the previous year and a record high that exceeded analyst estimates of 35.7 trillion won

Soaring Memory Prices Signal Structural Shift in Sector

The memory chip market is experiencing what executives describe as a structural shift rather than a typical cyclical upturn. Joon Deok Park, head of DRAM marketing at SK Hynix, emphasized that "the current cycle seems different from the past as memory price upswings are driven by structural changes rather than temporary demand and supply"

2

. This transformation is reflected in dramatic price increases across the board. Contract prices for certain DRAM chips jumped nearly 83 percent in the first quarter from the previous quarter, while prices for some NAND products soared around 160 percent, according to TrendForce

.

The benchmark contract price for 8 gigabits of DDR4 PC memory has risen for 11 consecutive months, hitting roughly $13 last month

1

. The average selling price of DRAM climbed 60.8 percent in the first quarter from the previous quarter, while NAND rose 55.3 percent, according to Mirae Asset Securities estimates

1

. SK Hynix expects this favorable pricing environment to continue "for the time being," as customers prioritize procurement over pricing amid supply constraints

Production Capacity Expansion and Capital Spending Surge

Responding to sustained demand, SK Hynix announced that capital spending will increase significantly this year from 30.2 trillion won in 2025

1

. In March, the company committed to purchasing 11.95 trillion won (approximately $8 billion) worth of EUV lithography tools from ASML by 2027

3

. The company is accelerating capacity expansion, including bringing forward the opening of a new memory chip plant and building infrastructure at the Yongin Cluster while ramping up the M15X fab

3

. Additionally, SK Hynix plans to spend 19 trillion won to build a new factory in South Korea's Cheongju

5

.

Samsung, SK Hynix's larger rival, is similarly mobilizing resources, planning to spend more than 110 trillion won on chip capacity expansion and research this year in an effort to seize the lead in AI semiconductors

1

. This massive investment wave across the semiconductor industry underscores the intensity of competition and the scale of anticipated demand from AI data centers.

Chip Wafer Shortage Expected to Persist Through 2030

SK Group Chairman Chey Tae-won has warned that the global chip wafer shortage is likely to persist until 2030, as demand driven by the AI boom continues to outpace supply

3

. He stated in March that building additional wafer supply could take at least four to five years, with a projected shortfall exceeding 20 percent

4

. This extended timeline for capacity additions means supply constraints will continue to support pricing power for memory makers well into the future.

SK Hynix noted that customer demand for high-bandwidth chips used in AI processors over the next three years far exceeded its production capacity

2

. The company emphasized that as AI evolves from large model training to agentic AI, which repeatedly performs real-time inference across various service environments, the foundation for memory demand is expanding across both DRAM and NAND flash

3

.

AI Servers and Inference Workloads Drive Sustained Demand

Demand for AI server chips remains strong, increasingly driven by inference workloads where applications such as chatbots generate responses

2

. SK Hynix dismissed concerns that memory-efficiency technologies such as Google's TurboQuant might reduce chip demand, arguing instead that they would expand memory demand by enhancing the economic viability of AI services. "The advancement of the memory optimisation technology will actually serve as a catalyst for driving memory demand further by expanding the AI ecosystem," Park explained

Along with Samsung Electronics, SK Hynix is supplying HBM to Nvidia for its forthcoming "Vera Rubin" AI platform, expected to further boost AI capabilities

5

. Reports suggest that memory chip suppliers are entering into long-term supply agreements of three years or more with Big Tech companies, with some customers seeking options to extend contract durations beyond the initial term, underscoring their emphasis on supply stability

Market Implications and Future Outlook

SK Hynix shares have surged approximately 90 percent this year after more than tripling in 2025, with the company's market value climbing to around $590 billion, surpassing chip equipment maker ASML's $570 billion

3

. Over the past 12 months, shares have skyrocketed by around 600 percent, helping push Seoul's benchmark Kospi stock index to record highs

5

.

Kwon Seok-joon, a professor at Sungkyunkwan University in Seoul, noted the clear structural change in the market: "Where the market was once driven by cyclical commodity chips, demand for AI-specialised memory chips is getting bigger now, extending the upcycle. Based on current long-term contracts, it could last through next year and possibly to 2028"

2

. However, some analysts remain cautious about cyclicality returning. Jorry Noeddekaer of Polar Capital stated, "We are, in a way, in a new paradigm for memory, but this idea that you will never ever see cyclicality in memory -- we are not buying that"

1

.

Chairman Chey Tae-won cautioned in February that losses remain a possibility in the future in an era of rapid technological shifts, highlighting mounting infrastructure challenges. He said SK Group is exploring building power plants alongside AI data centers, as failure to meet energy demand could be "disastrous"

1

. The company also noted that geopolitical risks from the Middle East conflict would have limited short-to-long-term impact on material supply, citing sufficient inventories and diversified sourcing
