SK Hynix shares rose after announcing a record $28.6 billion share buyback program, driven by unprecedented profit margins from surging artificial intelligence memory demand.
SEOUL — Shares of SK Hynix Inc. rose modestly in U.S. trading Friday, extending gains sparked by the company’s announcement of a record share repurchase program. The South Korean memory chipmaker continues to benefit from surging demand for high-bandwidth memory used in artificial intelligence systems.
Trading under the ticker SKHY, the American depositary receipts advanced approximately 0.45% to $163.82 during morning Nasdaq sessions. The advance followed a stronger session the previous day, when the ADRs climbed more than 4% after SK Hynix outlined plans to buy back and cancel 40 trillion won, or roughly $28.6 billion, of its outstanding shares.
The repurchase covers approximately 24.07 million shares, representing about 3.3% of outstanding stock, and is scheduled to run from mid-August through mid-November, after which the shares will be retired. SK Hynix also raised its shareholder-return target to more than 50% of cumulative free cash flow generated between 2025 and 2027, up from a previous cap of 50%. The company noted it would consider additional buybacks and dividends, with further details expected later this year.
In a regulatory filing, SK Hynix stated the decision "stems from the assessment that the Company's intrinsic value—underpinned by its business competitiveness, robust cash generation capability, and mid-to-long-term growth potential—is not fully reflected in its current stock price."
The buyback ranks among the largest in South Korean corporate history and arrives amid volatile trading across semiconductor equities. Seoul-listed SK Hynix shares had fallen sharply earlier in the week during a broader tech selloff before rebounding following the announcement. The company closed the second quarter with a net cash position of approximately 69 trillion won, providing substantial financial flexibility to fund shareholder returns while sustaining heavy capital investment.
SK Hynix has emerged as a primary beneficiary of the AI-driven memory supercycle. In the second quarter of 2026, the company reported record financial results, with revenue reaching 79.32 trillion won—a 257% increase year-over-year and a 51% sequential rise. Operating profit climbed to 60.54 trillion won, reflecting a 76% operating margin, while net profit reached 93.92 trillion won. Cumulative first-half revenue surpassed 100 trillion won for the first time in the company’s history.
Management attributed the performance to robust sales of high-value products, particularly high-bandwidth memory alongside advanced DRAM and NAND deployed in data centers. "As AI evolves into agentic forms that perform complex tasks on behalf of users and expands across various services, the underlying demand base for memory is broadening," the company stated in its earnings release. "Consequently, a structural shift is occurring where demand for both AI memory and conventional memory is expanding in tandem."
SK Hynix commenced mass shipments of its HBM4 products in the second quarter and plans to further ramp production in the second half of the year. The company emphasized the technology’s superior operating speeds, power efficiency, and cost competitiveness. It has finalized long-term agreements with approximately 10 key customers and continues negotiations with additional clients to secure multi-year supply contracts.
"In a market environment where customer demand exceeds supply capabilities, the ability to deliver requested volumes in a timely manner has emerged as a core business competitiveness," the company stated. Industry observers note that SK Hynix has maintained a leading position in the HBM market, particularly for Nvidia's AI accelerators, though competition from Samsung Electronics and Micron Technology remains intense as all three firms expand production capacity.
To support longer-term growth, SK Hynix has committed to substantial capital expenditures. The company plans investments in the high 40 trillion won range this year and recently announced 54 trillion won in spending for new facilities in Yongin and Cheongju to expand AI memory production. Cleanroom capacity from these projects is not expected to come online until late 2028 at the earliest. Executives have indicated that tight supply conditions could persist well beyond the current decade.
Wall Street analysts remain largely constructive on the stock. Consensus ratings lean toward Strong Buy, with average price targets implying substantial upside from current levels. Several firms have noted that the expanded buyback helps narrow the valuation gap relative to U.S. peers and signals management’s confidence in sustained free cash flow generation.
The ADR listing is relatively recent, granting U.S. investors direct access to one of the world’s leading memory producers. Trading volumes have remained elevated as the stock increasingly serves as a proxy for AI infrastructure spending. Memory prices have surged across both specialized HBM and conventional server DRAM and enterprise SSDs, supporting elevated margins industrywide.
Risks remain inherent to the sector. The memory business has historically been cyclical, and any slowdown in hyperscaler capital spending or faster-than-expected capacity additions could pressure pricing. Geopolitical developments and currency fluctuations also impact results for a company primarily listed in Seoul. Recent analyst reports have flagged potential quarterly fluctuations in HBM shipments linked to the rollout timing of next-generation AI platforms.
Nevertheless, the combination of record profitability, multi-year customer contracts, and a decisive capital-return program has reinforced investor focus on SK Hynix’s critical role in the AI supply chain. The company continues to prioritize technological leadership and disciplined capacity expansion as demand for high-performance memory extends from training clusters into inference workloads and broader computing architectures.
Market participants will closely monitor third-quarter results and any additional details regarding shareholder returns for insights into how management balances reinvestment needs with cash distribution. For now, the buyback announcement stands as a tangible demonstration of management’s confidence in the durability of the current market cycle.
