SK Hynix chairman Chey Tae-won is selling $700 million of his holding in the world's second-largest memory maker — a 2.26% stake — to fund a court-ordered divorce settlement of $644 million payable to his ex-wife, Roh Soh-yeong.

The sale follows a July ruling in which a court ordered Chey to pay Roh the $644 million. The settlement concludes one of South Korea's most closely watched corporate-legal disputes, tied to a marriage that lasted 35 years. Roh, daughter of former South Korean President Roh Tae-woo, heads the Seoul art institution Art Centre Nabi.

What is Chey actually selling?

The $700 million disposal covers a 2.26% stake in SK Hynix. Chey's total position stands at 17.76% of the company — a holding the source values at roughly $240 billion, making the divested tranche a small fraction of his overall exposure. He remains the company's dominant individual shareholder after the transaction.

The scale matters for the market. A 2.26% block in a company of Hynix's liquidity is large enough to move the share price if handled carelessly, which is precisely what the company says it has tried to avoid.

How is SK Hynix managing the market impact?

The company said it carefully reviewed the transaction structure and size "to minimise the impact on the market and shareholders while continuing responsible management".

That phrasing signals two concerns: preventing a price dislocation from a large block trade, and reassuring investors that the chairman's personal legal affairs will not divert the company from its operational course.

Why the timing cuts both ways

Chey is selling into the strongest memory market in years. SK Hynix shares have risen more than 182% this year on the back of the memory price boom, driven by tight supply and surging demand for high-bandwidth and conventional DRAM alike. A high share price means the 2.26% stake raises the full $700 million needed with the least dilution of Chey's remaining position.

The company also raised $26.5 billion in the US in July, underscoring the depth of investor appetite for Korean memory paper at this point in the cycle.

The offsetting risk is sentiment. Any large insider sale at a cyclical peak invites scrutiny, even one triggered by a personal court order rather than a view on the fundamentals. The company's emphasis on "responsible management" is aimed squarely at that read.

What does this change for SK Hynix?

Operationally, very little. The sale does not alter control: Chey retains a 17.76% holding less the 2.26% disposed, keeping him far ahead of any other individual shareholder, and the company's capital position — bolstered by the July $26.5 billion US raise — is untouched.

The transaction does, however, land at a moment when Hynix stock is priced for continued memory strength. With shares up 182% year to date and pricing power still firm across DRAM, the test for the stock is whether the block sale absorbs cleanly — and whether the memory upturn that inflated the value of Chey's stake carries into next year.
