2. Financial Trend

S-Oil's financial performance deteriorated sharply in 2024. Revenue grew modestly to KRW 36.6 trillion (FY2024) from KRW 35.7 trillion (FY2023), representing 2.5% growth. However, this follows a significant decline from KRW 42.4 trillion in FY2022.

Most alarming is the profitability collapse: operating profit plunged 69% from KRW 1,355 billion (FY2023) to just KRW 422 billion (FY2024). The company recorded a net loss of KRW 193 billion in 2024, a dramatic reversal from net income of KRW 949 billion in 2023 and KRW 2,104 billion in 2022. Operating margin compressed from 3.8% to 1.2%, while the company fell into negative net margin territory.

The balance sheet shows concerning leverage trends. Total liabilities surged 26% to KRW 15.8 trillion (2024) from KRW 12.5 trillion (2023), while total equity declined to KRW 8.7 trillion from KRW 9.0 trillion. The debt-to-equity ratio deteriorated significantly to 1.81x from 1.39x. Retained earnings decreased to KRW 7.0 trillion from KRW 7.4 trillion, reflecting the net loss and potential dividend payments.

4. Key Risks

Refining margin compression risk: The 69% operating profit decline despite stable revenue indicates severe margin pressure, likely from falling crack spreads (refining margins) amid weak global demand and capacity oversupply. This structural challenge may persist.

Balance sheet deterioration risk: The company's leverage increased substantially while generating negative earnings, with total liabilities up KRW 3.2 trillion year-over-year. Continued losses could strain financial flexibility and dividend capacity, particularly concerning given the KRW 349 billion reduction in retained earnings beyond the reported loss.

5. Investment Consideration

S-Oil faces a critical profitability crisis with a swing to net losses and deteriorating leverage, requiring investors to assess whether current refining cycle weakness is temporary or signals structural margin compression in a transitioning energy landscape.
