SK Hynix paid a final installment of $2.235 billion in March 2025 to complete its acquisition of Intel's NAND businessCITE:E7. Separately, the company acquired SK Powertech Co., Ltd. and brought it into its consolidated financial statementsCITE:E8.
SK Hynix hedges exposure to the US dollar, euro, Chinese yuan, and Japanese yen using derivative instruments including cross-currency interest rate swapsCITE:E9. The company applies these tools to reduce the impact of interest rate and currency fluctuations tied to its international operationsCITE:E9.
SK Hynix is planning a ₩10 trillion plant investment in JapanCITE:E10. News of the plan coincided with gains in two Japan-focused semiconductor exchange-traded fundsCITE:E10.
Taken together, the reported figures show SK Hynix entering its Japan investment plan from an improved financial position: a debt-to-equity ratio that dropped from 62.15% to 48.13% and operating cash flow of ₩18.19 trillion in the first half of 2025, alongside a completed $2.235 billion final payment on the Intel NAND acquisitionCITE:E6CITE:E4CITE:E7. The ₩10 trillion Japan plant figure sits within that same reporting window and was followed by moves in the two Japan-focused semiconductor ETFs cited in the same reportCITE:E10.

The numbers in this report line up in a specific order: SK Hynix's debt-to-equity ratio dropped from 62.15% to 48.13% and operating cash flow hit ₩18.19 trillion in H1 2025, the same period in which it finished paying $2.235 billion for Intel's NAND business. A ₩10 trillion Japan plant plan surfacing right after that balance-sheet improvement reads as a company that has freed up room on its books rather than one stretching for a first big commitment. The figure worth tracking next is whether SK Hynix's debt-to-equity ratio and operating cash flow hold their current levels once the Japan capex plan moves from announcement to actual outlays — that will show whether the improved 48.13% ratio was a one-off post-acquisition reading or a sustained shift in capital structure.
US Commerce Secretary Howard Lutnick is pushing a new round of semiconductor tariffs that would tie tariff-free import quotas to how much chip manufacturing a company commits to build inside the United States, a design that could extend duties beyond the advanced processors already taxed since January 2026 to AI servers, laptops and gaming consoles.
Taiwan's benchmark TAIEX closed at 46,331.45 points on August 28, up 356.23 points and above the 46,000 threshold, on turnover of roughly NT$1.023 trillion. TSMC rose NT$10 to NT$2,420, and 36 listed stocks hit their daily limit after NVIDIA's earnings beat lifted sentiment at the open.
Four hyperscalers are on track to spend roughly $725 billion combined on AI infrastructure in 2026, up about 77% from 2025's $410 billion, and NVIDIA's data center revenue confirms real near-term demand with 117% year-over-year growth. Yet Bain projects an $800 billion annual revenue shortfall by 2030, Michael Burry alleges $176 billion in understated depreciation, and circular deals linking NVIDIA, OpenAI, and Oracle draw dot-com comparisons — even as NVIDIA and JPMorgan Asset Management reject the bubble framing.
