Revenue fell for three straight years, from 51.72 trillion won in 2022 to 44.56 trillion in 2023, 38.39 trillion in 2024 and 35.73 trillion in 2025, largely because oil and LNG prices that feed into selling tariffs eased.
Operating profit, by contrast, jumped from 1.55 trillion won in 2023 (3.5% margin) to 3.00 trillion won in 2024 (7.8%) before easing to 2.10 trillion won in 2025 (5.9%).
Volatility is far greater at the net level: net income attributable to owners swung from 1.49 trillion won in 2022 to a loss of 761.2 billion won in 2023, then 1.15 trillion won in 2024 and just 133.0 billion won in 2025.
In the fourth quarter of 2025 the company posted revenue of 8.99 trillion won and operating profit of 473.6 billion won yet a net loss attributable to owners of 406.9 billion won; Hana Securities noted that more than 600 billion won of impairment was recognized in that quarter at Mozambique, Australia's GLNG and Prelude and other assets on lower long-term oil price assumptions and discount rate changes.
The picture shifted in 2026: first-quarter revenue of 11.80 trillion won, operating profit of 910.0 billion won and net income attributable to owners of 548.6 billion won were followed by second-quarter revenue of 7.51 trillion won, operating profit of 675.3 billion won and net income of 339.1 billion won, well above the second quarter of 2025 (revenue 7.63 trillion won, operating profit 404.6 billion won, net income 85.4 billion won).
Management said revenue declined on lower selling prices as oil prices fell, while operating profit rose on lower cost of sales and higher profits at subsidiaries including those in Mozambique, and that overseas project operating profit in Myanmar, Mozambique and elsewhere rose to 330.9 billion won in the first half from 192.0 billion won a year earlier.
Summing the four most recent quarters (third quarter 2025 through second quarter 2026), net income attributable to owners was 567.9 billion won, far above the impairment-hit full-year 2025 figure.
Balance-sheet metrics also turned: operating cash flow recovered from negative 14.58 trillion won in 2022 to 5.89 trillion in 2023, 3.63 trillion in 2024 and 6.54 trillion in 2025, while total liabilities fell from 52.01 trillion won in 2022 to 42.83 trillion in 2025 and the debt-to-equity ratio from 499.6% to 396.6%.
