S-Oil stock gains 11.69 percent after ownership change news makes waves in Korea

S-Oil stock (ISIN KR7010950004) was last at KRW 166,200 on KRX on October 2, 2026 at 3:30 p.m. KST, up 11.69 percent from the prior close. As Jaekyung Daily reported on October 2, the gain followed news of a change in S-Oil's largest shareholder.

Ownership change meets stronger margins

The shareholder disclosure arrived as refining economics improved. Aju Press reported on October 2 that S-Oil's second-quarter revenue reached KRW 11.34 trillion, up 40.9 percent from the same period a year earlier, while operating profit recovered to KRW 965.0 billion from a loss in the prior-year quarter.

The segment split adds useful context. Refining contributed KRW 532.4 billion of operating profit in Q2 2026, while lubricants generated KRW 477.4 billion, according to Aju Press. That mix gives S-Oil more than one earnings lever, but it also leaves results sensitive to product spreads and crude-price swings.

Analysts raise the earnings bar

On September 29, Samsung Securities issued a Buy rating and lifted its target from KRW 165,000 to KRW 210,000, a 27.3 percent increase, as reported by NewsPim. The same report cited a Q3 operating-profit forecast of KRW 1.37 trillion, 42 percent above Q2, and a 26 percent consensus beat estimate.

For the wider analyst view, Bullstory listed a Strong Buy consensus from 18 analysts on September 12, with an average target of KRW 169,611, a low target of KRW 130,000 and a high target of KRW 210,000.
