South Korea’s two largest memory chipmakers are swimming in cash, and their shareholders have noticed. Investors in Samsung Electronics and SK Hynix are turning up the pressure for bigger dividends and share buybacks, arguing that record profits from artificial intelligence demand should translate into meaningful returns, not just ambitious reinvestment plans.

The timing is pointed. Both companies posted strong quarterly results in July 2026, fueled by explosive demand for high-bandwidth memory chips used in AI accelerators. SK Hynix alone reported a 557% year-over-year jump in Q2 2026 operating profit, driven almost entirely by HBM demand. Yet both stocks sold off sharply after earnings, with Samsung down roughly 37% from its June peaks and SK Hynix off approximately 48%.

A cash pile that would make most countries blush

The combined projected net cash position of Samsung and SK Hynix is expected to reach $263 billion by the end of 2026. For context, that figure dwarfs Nvidia’s estimated cash reserves of around $102 billion, despite Nvidia being the company most investors associate with the AI hardware wave.

Currently, both companies target returning around 50% of free cash flow to shareholders. Investors are pushing that figure toward 80%, a demand that would represent a significant philosophical shift in how the companies manage their balance sheets.

A retail investor group called ACT launched a formal campaign during the week of August 6, 2026, specifically targeting Samsung. The group is calling for a $32 billion share buyback, citing the stock’s steep decline as justification for deploying some of that accumulated cash to support the share price.

The tension between returning cash and building the future

Both companies are not exactly idle with their capital. Samsung and SK Hynix have pledged a combined investment of 3,200 trillion won in domestic AI-related initiatives, a number large enough to make the shareholder return debate feel like a genuine either/or question.

Korean corporate governance has historically favored company builders over capital returners, a cultural and structural tendency that foreign institutional investors in particular have pushed back against for years. The current campaign represents a louder, more coordinated version of that same frustration.

Both companies have acknowledged the shareholder concerns and indicated that enhanced capital return announcements are coming soon, without committing to specific timelines or figures beyond that.
