SK Square (ISIN KR7402340004) faced a new governance question on October 20, 2026, after regulators challenged Solidigm's proposed U.S. listing. The issue matters because SK Square is the largest shareholder in SK hynix, which owns Solidigm, and concerns about dilution weighed on the group.

Seoul Economic Daily reported on October 20, 2026, that financial authorities viewed the proposed listing as conflicting with dual-listing rules. The report said regulators were still considering the legal interpretation for an overseas subsidiary listing, while investor concerns centered on the effect on existing shareholders.

Solidigm risk reaches the portfolio

The market connection is direct: SK Square holds the key listed exposure through its stake in SK hynix. The Seoul Economic Daily report said SK Square fell 4.36 percent to KRW 746,000 during the October 20 session, while the broader KOSPI also weakened.

The proposed listing could raise funding for Solidigm, but the ownership structure creates a counterweight. Outside capital may support investment, while dilution concerns can reduce the value investors assign to SK Square's indirect semiconductor exposure.

What does the earnings base show?

SK Square's second-quarter 2026 revenue was KRW 329.00 billion, down 19.20 percent from the same period a year earlier, while operating profit reached KRW 19.20 trillion and net income was KRW 18.70 trillion, according to ATS View. The company's investor-relations page lists the Q2 2026 portfolio update dated August 14, 2026.

Three developments shape the story

On August 14, 2026, SK Square's Q2 update carried revenue of KRW 329.00 billion. On October 12, 2026, coverage of its Japanese physical AI investment appeared through three outlets, according to ATS View. On October 20, 2026, the Solidigm listing dispute was linked to a 4.36 percent decline in SK Square during the session.

Dates investors can map

The next reported earnings date is November 12, 2026, according to TradingView. The date gives investors a defined checkpoint for judging whether the second-quarter earnings scale is continuing into the third quarter.

Portfolio value meets dilution risk

SK Square's market capitalization stood at KRW 97.6 trillion on October 20, 2026, while the second-quarter operating result was KRW 19.20 trillion. That contrast explains why the Solidigm structure matters: operating earnings can expand, but ownership and capital-allocation decisions still determine how much value reaches the holding company.
