South Korea’s SK Hynix reported a 158% year-on-year surge in operating profit for the March quarter, driven by booming demand for its high bandwidth memory (HBM) used in artificial intelligence chipsets. Despite the stellar growth, the company issued a cautionary note on future demand, citing ongoing macroeconomic uncertainties and potential tariff risks.
Earnings Snapshot:
-
Revenue: 17.64 trillion won ($12.36 billion) vs. 17.26 trillion won expected
-
Operating Profit: 7.44 trillion won vs. 6.62 trillion won expected
While year-on-year growth remained robust — 42% increase in revenue and 158% jump in profit — the company saw a quarter-on-quarter decline:
-
Revenue fell 11%
-
Operating profit dropped 8% from the record highs seen in Q4 2024
AI Fuels Memory Market Momentum
SK Hynix credited its performance to soaring AI demand, particularly from hyperscale data centers and AI server clients such as Nvidia. The company’s dominant position in the HBM segment, which is critical for AI computing, has helped it outpace rivals.
A report from Counterpoint Research stated that SK Hynix captured 70% of the HBM market by revenue in Q1 2025. It also overtook Samsung Electronics in the global DRAM market for the first time, holding a 36% share compared to Samsung’s 34%.
“Our focus on high-value AI memory solutions has paid off,” a company executive said. “This marks a turning point in our competitive position.”
Tariff Warnings Cast a Shadow
Despite the AI-fueled success, the company warned of demand volatility in the second half of the year.
“There are growing concerns that tariffs may be applied to semiconductor products,” an SK Hynix executive said during the earnings call, referencing potential fallout from ongoing U.S. tariff policies.
Though current reciprocal measures have been suspended, global trade instability — especially with the U.S.–China tech tensions — could impact memory chip shipments.
Expansion Plans and Government Support
To meet future demand, SK Hynix announced it will build a new DRAM fabrication plant in Cheongju, South Korea. The facility will support production of next-generation memory, including HBM.
-
Construction starts: End of April 2025
-
Mass production goal: November 2025
-
Total investment: Over 20 trillion won long-term
This aligns with a broader industry push backed by government support. Earlier this month, South Korea unveiled a 33 trillion won support package for its semiconductor sector — a notable increase from 26 trillion won committed last year.
AI Ecosystem Growth Driving Demand
SK Hynix cited expanding AI initiatives, such as open-source model DeepSeek’s R1, as catalysts for memory demand. The adoption of AI-powered consumer electronics, servers, and sovereign AI projects are expected to further drive DRAM and HBM consumption throughout 2025.
Market Reaction and Outlook
Despite the strong earnings report, SK Hynix shares slipped 0.9% in Asia trading — reflecting investor caution over global trade dynamics and near-term profit softening.
Still, the company remains confident:
“We are on solid footing for long-term growth in AI and memory,” the company said in a statement.
