S-Oil (ISIN KR7010950004) became the subject of a major ownership filing after Aramco shifted 63.00 percent of the refiner on October 1, 2026. ChosunBiz reported that the transfer moved the stake from Aramco's Netherlands subsidiary to a Singapore entity while leaving ultimate Aramco control unchanged. For S-Oil stock, the central question is whether the ownership reshuffle changes capital allocation or investment priorities.

Quarterly figures show a sharper rebound

ATS View reported second-quarter 2026 revenue of KRW 11.3 trillion, up 40.9 percent from the same quarter a year earlier. Operating profit reached KRW 965 billion, producing an 8.51 percent margin based on those reported figures.

The improvement was visible against second-quarter 2025, when ATS View listed revenue of KRW 8.05 trillion and an operating loss of KRW 344 billion. The latest result therefore combines a KRW 3.25 trillion year-over-year revenue increase with a KRW 1.31 trillion swing in operating profit.

What does the transfer mean?

The ownership event is an internal Aramco restructuring rather than an external sale of S-Oil. AWAKEPLUS reported that Aramco Downstream Asia reached 63.41 percent through an over-the-counter transfer of 71,387,560 common shares on October 1, 2026, while the October 2 filing showed 63.43 percent after the ownership report.

That distinction matters because control continuity and operating recovery point in different directions. The shareholder change affects the governance map, while the second-quarter figures show that refining profitability had improved materially from the prior-year loss.

Three dated steps in the story

The sequence began on August 3, 2026, when S-Oil reported second-quarter revenue of KRW 11.3 trillion and operating profit of KRW 965 billion. On October 1, 2026, Aramco Downstream Asia acquired 71,387,560 common shares and reached 63.41 percent. On October 2, 2026, the ownership filing recorded a 63.43 percent holding.

A November filing date is listed

ATS View lists November 16, 2026, as the deadline for S-Oil's quarterly filing. That date gives investors a concrete checkpoint for the next reported period, while the ownership transfer remains the latest governance event in this article.

Governance and earnings now meet

S-Oil operates in refined petroleum and petrochemicals, with its shares listed on the Korea Exchange KOSPI market under ticker 010950. The combination of KRW 11.3 trillion in second-quarter revenue and an 8.51 percent operating margin gives the ownership change a financial backdrop rather than leaving it as a purely structural event.
