SK Hynix, key supplier to AI Chip giant Nvidia, profit tops forecast Samsung results, but shares dip on demand outlook

• Benefits from AI surge ahead of rivals Samsung, Micron
• Profit exceeds rival Samsung’s forecast Q4 profit first time -analysts
• SK Hynix shares fall as much as 4.7% on demand outlook for memory chips

SEOUL, Jan 23 (Reuters) – South Korea’s SK Hynix (000660.KS), forecast sales of its high-end semiconductors used in generative artificial intelligence chipsets would more than double this year, after reporting a quarterly profit record that beat a results estimate for rival Samsung.

Shares in SK Hynix, a key supplier to AI chip giant Nvidia (NVDA.O), however, fell as much as 4.7% as the company warned of steeper demand declines in commodity memory chips used in smartphones and computers as Chinese competition grows. The shares have since recovered to trade down 0.2% at midday.

SK’s factory investment plan for high-bandwidth memory (HBM) chips this year also underwhelmed investors, analysts said.

Before the result, SK Hynix shares had jumped about 30% this year on bullish sentiment driven by its business discussions with Nvidia, outperforming larger competitor Samsung (005930.KS), whose shares rose 2% over the same period.

SK Hynix Chief Financial Officer Kim Woo-hyun told analysts on an earnings call,

Uncertainties exist for the memory chip market this year as trade protectionism grows and geopolitical risks deepen, while PC and smartphone companies adjust inventories,

The company said supply will remain tight for high-performance chips as a result of rising demand, but demand declines will accelerate for legacy products.

Lee Min-hee, an analyst at BNK Investment & Securities, said while fourth-quarter results were strong, SK Hynix’s forecast for first-quarter chip shipments was weaker than expected and disappointed investors.

Lee said,

I had forecasted just above 6 trillion won operating profit for Q1, but now I’m expecting around 5.5 trillion won,

SK Hynix said its shipments of DRAM and NAND flash memory chips would decline by between 10% and 20% in the first quarter from the previous quarter.

MODEST CAPEX PLAN

The world’s second-biggest memory chipmaker posted an operating profit of 8.1 trillion won ($5.64 billion) in the October-December quarter, slightly above expectations and exceeding Samsung’s estimated fourth-quarter operating profit of 6.5 trillion won.

the numbers hold, this would be the first time that SK Hynix’s quarterly operating profit beat Samsung’s total operating profit, analysts said, as its rival lags in supplying high-end high-bandwidth memory (HBM) chips to Nvidia.

SK Hynix said HBM chips accounted for 40% of its total DRAM revenue in the fourth quarter. Overall, its revenue for the quarter rose 75% year-on-year to 19.8 trillion won, while its operating profit was up more than 20-fold from a year earlier when it was coming out of the biggest chip industry downturn in over a decade.

The company has been increasingly outperforming rivals Samsung and U.S.-based Micron Technology (MU.O), in recent quarters, as it benefits the most from AI-driven appetite for high-end memory chips following its early entry and large investments in HBM chip development.

But SK Hynix told analysts its 2025 capital expenditure would rise only slightly from last year, with investments focusing on HBM production and new factories in South Korea.

Jung Min-gyu, an analyst at Sangsangin Investment & Securities, said :

SK Hynix’s conservative capex plan for HBM chips fuelled concerns about a slowdown in demand,

“The capex plan fell short of investor expectations for SK Hynix to sharply boost investments on HBM production,”

A SK Hynix executive said the company had already begun supply talks for 2026 for the HBM chips used in AI chipsets and expected to have better visibility in the first half about shipment plans for next year.

The executive, Vice President Kim Ki-tae, head of HBM Sales & Marketing, said.

The AI industry has a potential to grow above most expectations and would require huge computing power. There’s no doubt about long-term demand for HBM chips,

SK Hynix said it began supply of 12-layer HBM3E chips, the most advanced HBM model currently in mass production, to a customer in the fourth quarter.

It expects it will start supplying even more advanced 16-layer HBM4 chips in the second half of 2026 and that Chinese rivals will face difficulties in developing advanced chips due to U.S. restrictions.
