South Korean semiconductor manufacturer SK Hynix reported significant growth in its third-quarter earnings, driven by robust demand for artificial intelligence (AI) chips. For the three months ending September 30, the company posted an operating profit of 83.33 trillion won ($62.5 billion), representing a more than sixfold increase compared to the same period last year. Revenue surged 32 percent to 104.62 trillion won, marking the sixth consecutive quarter of record profits.
The company attributed its strong performance to rising memory prices and heightened sales of high-bandwidth memory (HBM) products, which are critical components for AI infrastructure. SK Hynix indicated that its production of DRAM and HBM chips has been fully booked through 2029, underscoring a sustained shortage expected to continue until at least 2030 due to expanding AI adoption across major technology firms, smaller enterprises, and national-level projects.
Executives highlighted what they described as a “virtuous cycle” in which AI-driven productivity gains and new revenue streams, such as in software development and customer service, are fueling broader AI integration and increased infrastructure investment. The company forecasts further growth in HBM revenue in the upcoming year and plans to boost capital expenditure to meet rising demand.
Despite these record earnings, SK Hynix’s net profit stood at 39.78 trillion won, representing a decline from the previous quarter, which had benefited from gains related to the company’s stake in Japanese memory maker Kioxia. Nevertheless, the firm has announced plans to return approximately 100 trillion won ($75 billion) to shareholders this year through dividends, share buybacks, and cancellations, including an additional 60 trillion won in new returns following the completion of an earlier 40 trillion-won program.
The stock market reaction was positive but measured; SK Hynix shares rose nearly 11 percent in Seoul following the earnings release but remained about 15 percent below levels from the previous month amid ongoing volatility in semiconductor and AI-related stocks. The Kospi index, heavily influenced by technology shares including SK Hynix which accounts for roughly one-fifth of the index, gained over 6 percent in tandem.
SK Hynix also addressed the recent decision to halt the planned U.S. initial public offering (IPO) of its Solidigm subsidiary, which specializes in solid-state drives. Chief Executive Kwak Noh-jung cited market turbulence and declining semiconductor share prices as factors behind the suspension. The IPO had faced additional scrutiny from Korean regulators concerned about investor interests.
Market analysts noted that while SK Hynix’s current performance is strong, there is cautious sentiment surrounding the sustainability of AI spending growth and the semiconductor industry’s funding environment. Some investors remain watchful of potential demand fluctuations beyond the near term.
Founded in 1983 as Hyundai Electronics, SK Hynix has become a key supplier to major global tech companies such as Nvidia, Apple, and AMD, with its HBM chips playing a pivotal role in powering AI systems. The company’s performance is now closely regarded as a barometer for the broader expansion of AI technology worldwide.
