AI Boom Powers SK Hynix to Record Profits – But Tariff Storm Looms Ahead

SK Hynix Reports Strong Q1 Earnings Driven by AI Chip Demand, Warns of Future Uncertainty

SK Hynix, a leading memory chip maker from South Korea and key supplier to tech giant Nvidia, had a very strong start to 2025. The company’s first-quarter profit more than doubled, thanks to the growing demand for chips used in artificial intelligence (AI). While the company is riding high on the current AI boom, it has also issued a cautious note about potential risks in the future, especially due to the uncertainty around U.S. trade tariffs.

Strong Q1 Results Boosted by AI

In the first quarter, SK Hynix reported an operating profit of 7.4 trillion won (about $5.2 billion), which is a 158% increase compared to the same period last year. This figure also beat analysts’ expectations by a wide margin. The company’s revenue also rose by 42% to 17.64 trillion won ($12.36 billion).

These results mark the second-highest quarterly operating profit in the company’s history. A big part of this success comes from high-bandwidth memory (HBM) chips, which are in high demand due to their use in AI servers. SK Hynix is a major supplier of these chips to Nvidia, a company at the center of the AI revolution.

Stockpiling and Tariff Concerns

The strong earnings were also helped by stockpiling of chips by tech companies who fear possible price hikes due to U.S. tariffs. With the U.S. investigating semiconductor imports over national security concerns, many companies are preparing for potential changes by purchasing in advance.

However, SK Hynix believes that the impact of these tariffs on their AI chip business will be limited. According to Kim Ki-tae, head of the HBM sales and marketing team, there are no changes to the company’s sales plans for the year. He confirmed that SK Hynix is continuing to supply chips to major clients under existing agreements.

AI Boom Driving Demand

The AI wave is not slowing down, and SK Hynix expects that large tech companies will keep spending big on server chips. The growing popularity of AI features in smartphones is also expected to boost demand for mobile memory chips. Even though the company faces some risk from global economic uncertainty, the current momentum from AI is helping to cushion the impact.

A company executive mentioned that lower development costs and open-source AI projects are helping new players enter the market, which is pushing up demand for high-density memory chips even more. A good example of this trend is China’s DeepSeek, which recently developed a powerful AI model that works efficiently even with limited hardware.

Market Leadership and Future Plans

SK Hynix’s success in the AI memory market is clearly visible. A report from Counterpoint Research revealed that SK Hynix captured 70% of the HBM market by revenue in the first quarter. This performance even helped the company overtake long-time leader Samsung in the global DRAM market, achieving a 36% share compared to Samsung’s 34%.

To keep up with the rising demand, SK Hynix has announced plans to build a new chip production facility in Cheongju, South Korea. Construction will begin at the end of April, and the factory is expected to start mass production by November 2025. The total investment for this project will be over 20 trillion won in the long run.

Looking Ahead: Challenges and Opportunities

Despite the strong performance, SK Hynix warned that the second half of 2025 could be more unpredictable. The company pointed out that U.S. tariffs and other global trade tensions could affect demand. However, since a large portion of its products are shipped to countries outside the U.S., the direct impact might be limited.

Moreover, SK Hynix continues to benefit from strong demand from companies like Apple and Nvidia, which assemble many of their products in countries such as China, India, Mexico, and Taiwan. This makes SK Hynix less vulnerable to U.S. trade actions.

In addition, the South Korean government recently announced a 33 trillion won support package for its chip industry. This move is expected to help local companies like SK Hynix weather future trade challenges and continue investing in innovation.

Conclusion

SK Hynix is clearly riding the wave of the AI boom, with impressive first-quarter results and a dominant position in the HBM chip market. The company is expanding production and looking to maintain its lead in a competitive and fast-growing field. Still, the road ahead could be bumpy due to global economic and political uncertainties. For now, though, SK Hynix remains one of the biggest winners of the AI era.
