Kumho Petrochemical (011780.KS) posted Q1 2026 consolidated revenue of ₩1,780.0 billion (−6.7% YoY), operating profit of ₩59.4 billion (−50.7%), and net profit of ₩96.3 billion (−22.8%), as a crude-oil spike triggered by the U.S.-Iran conflict drove feedstock costs higher while equity-method income and affiliate dividends cushioned the bottom line.
A geopolitical oil shock erased months of spread improvement, cutting Kumho Petrochemical's operating profit in half — yet equity-method income from joint ventures contained the net-profit damage to less than a quarter.
