Shares of SK hynix rocketed as much as 13% in Seoul on August 20 after the memory chip giant unveiled a 40 trillion won ($28.7 billion) share repurchase program — the largest buyback in South Korean corporate history. The announcement, made after markets closed August 19, immediately reframes the investment case for a company already riding the biggest demand wave in semiconductor history. SK hynix's Record $29 Billion Buyback Signals AI-Fueled Confidence — But Can the Cash Machine Keep Running Fast Enough to Justify It?

Shares shifted dramatically as SK hynix unveiled the largest share repurchase in South Korean corporate history, a $28.7 billion program that will permanently retire roughly 3.3% of its outstanding stock over three months. The move comes after shares had fallen more than 50% in two months , making it as much a defensive floor as an offensive signal. The question now: is this a company distributing durable AI profits, or catching a falling knife with shareholder cash?

  • The Sheer Scale Says "We Have More Money Than We Know What to Do With"

SK hynix reported net cash of approximately 69 trillion won at the end of Q2 2026 , meaning the buyback consumes roughly 58% of that war chest. Cash and cash equivalents reached 88 trillion won, up 33.6 trillion won from the prior quarter, while total debt fell to 18.6 trillion won. That balance sheet didn't exist two years ago — it was built almost entirely on AI memory chip demand. The buyback is affordable today, but it also locks in a massive capital commitment through November.

  • Goldman Thinks This Is Just the Opening Act

Goldman Sachs estimates SK hynix will generate approximately 252 trillion won in cumulative free cash flow from 2025 to 2027. Assuming a roughly 55% return ratio, total shareholder payouts would reach about 140 trillion won — leaving roughly 70 trillion won in additional buyback capacity after this program and dividends. Goldman believes further buybacks and dividend increases may be announced at the Q3 earnings call in late October. That math depends entirely on AI spending holding up.

  • The Buyback Erases Dilution From the U.S. Listing

The cancellation of approximately 24 million shares exceeds the dilutive effect of roughly 17.7 million shares issued through recent ADR listings — the U.S.-traded stock certificates SK hynix created to tap American investors. Shareholders who worried the U.S. listing watered down their ownership now get a net positive.

  • A 50% Crash Preceded This — Not a Victory Lap

The company itself said its intrinsic value "is not fully reflected in its current stock price."

Citi analyst Peter Lee called the buyback "a meaningful floor for the share price, providing tangible downside support." Translation: management is trying to stop the bleeding, not celebrate. Before the announcement, SK hynix traded at a forward price-to-earnings ratio of just 5.7 with a 13% free cash flow yield — extraordinarily cheap for a company printing record profits but priced as though those profits are about to vanish.

The real test arrives in October's earnings. If AI memory orders soften, this buyback becomes an expensive promise. If they hold, it looks like the bargain of the decade.
