Why did S-Oil report a strong first-quarter operating profit in 2026 despite falling revenue?

S-Oil reported an operating profit of 1.2 trillion won ($817.97 million) in Q1 2026 — a sharp reversal from a 22 billion won loss a year earlier — primarily because its refining division posted an operating profit of 1 trillion won, driven by wider regional refining margins fueled by strong middle distillate demand amid crude supply disruptions, run cuts, and government-led export restrictions.

How is South Korea's domestic fuel price cap affecting S-Oil's profitability?

S-Oil stated on its earnings conference call that it was suffering 'significant losses' because the government's oil price cap system prevented it from linking domestic fuel prices to international oil prices; the company said it was too early to comment on the scale of losses or timing of compensation, as detailed standards for calculating losses had yet to be established, and any compensation would only be reflected in earnings once officially notified by the government.
