Investors want South Korea's top memory chipmakers to lift payouts after AI-driven high-bandwidth memory profits swelled cash reserves and both stocks slid sharply from June highs.
Samsung Electronics and SK Hynix are facing rising pressure to raise dividends and buy back stock after July 2026 earnings showed how strongly artificial intelligence demand is lifting memory-chip profits. SK Hynix reported a 557% year-over-year jump in second-quarter operating profit, driven largely by high-bandwidth memory chips used in AI accelerators, while both companies are projected by LSEG data and Reuters calculations to hold a combined $263 billion in net cash by the end of 2026, above Nvidia's estimated $102 billion. Yet Samsung shares have fallen roughly 37% from their June peak and SK Hynix about 48%, intensifying scrutiny of how the companies use their balance sheets. Both companies currently target shareholder returns of about 50% of free cash flow, but some investors want that closer to 80%, arguing the AI boom should produce more meaningful payouts. The campaign has sharpened around Samsung, where retail investor group ACT called during the week of Aug. 6, 2026 for a $32 billion share buyback. The companies say they are weighing stronger capital return plans even as they pursue a combined 3,200 trillion won in domestic AI-related investment, leaving the dispute at the center of a broader debate over capital allocation and the Korea discount.
