SK Inc (ISIN KR7034730002) was tied to a 1.34 percent stake sale worth KRW 544 billion on October 13, 2026, while regulators later flagged the Solidigm listing under dual-listing rules. According to Reuters, the Dell-linked fund bought the larger part of the stake sale planned by Chairman Chey Tae-won. On October 20, Seoul Economic Daily reported that financial authorities considered the proposed U.S. listing potentially inconsistent with dual-listing rules.

Three ownership steps changed the picture

The recent sequence began on August 28, 2026, when SK Inc proposed acquiring a remaining 4.8 percent stake in SK Signet for KRW 9.1 billion, according to Simply Wall St. On October 13, 2026, Reuters reported that DFO Public Investments agreed to acquire 972,493 SK Inc shares, equal to 1.34 percent, for KRW 544 billion. On October 20, 2026, Seoul Economic Daily reported that regulators had flagged the planned Solidigm listing, adding a shareholder-dilution concern to the group structure.

What does the ownership shift mean?

Chey Tae-won's direct holding is expected to fall to 15.5 percent from 17.8 percent, while his combined holding with relatives and affiliates is set to decline to 22.9 percent from 25.2 percent, according to Billionaires Africa on October 20, 2026. The same report said the transactions were due to settle on November 2, 2026. The figures point to a smaller direct stake but continued control through related holdings.

When is the next reporting date?

The next two dated milestones are the November 2, 2026, settlement of the stake transactions and the November 16, 2026, earnings date listed by TradingView. That calendar point gives investors a defined checkpoint for assessing operating performance alongside the ownership and listing questions.

Valuation meets a governance test

Simply Wall St put SK Inc's market capitalization at KRW 25.4 trillion on October 23, 2026. The October 20 regulatory warning therefore matters beyond the immediate listing plan: it tests whether future subsidiary funding can proceed without weakening the value assigned to existing shareholders.
