Annual revenue fell from KRW 1.4401 trillion in 2022 to KRW 1.2426 trillion in 2023 and KRW 1.1649 trillion in 2024, before rebounding to KRW 1.2017 trillion in 2025.
Operating profit, by contrast, rose steadily throughout the revenue downturn, from KRW 37.1 billion in 2022 to KRW 39.4 billion in 2023, KRW 45.9 billion in 2024, and KRW 73.3 billion in 2025, with operating margin improving each year from 2.6% to 3.2%, 3.9%, and 6.1%.
Net income attributable to owners contracted to KRW 14.7 billion in 2022 and KRW 7.6 billion in 2023 before jumping sharply to KRW 56.5 billion in 2024; since this increase far exceeded the concurrent rise in operating profit (from KRW 39.4 billion to KRW 45.9 billion), a substantial non-operating or one-off gain appears to have been reflected in that year's results.
Owners' net income improved further to KRW 59.1 billion in 2025, continuing the earnings recovery.
Quarterly results display pronounced seasonality: in Q2 2025 revenue was KRW 201.2 billion with operating profit of only KRW 0.8 billion and a net loss of KRW 0.6 billion, before turning profitable in Q3 2025 with net income of KRW 5.6 billion, then surging in Q4 2025 to revenue of KRW 346.4 billion, operating profit of KRW 23.6 billion, and net income of KRW 27.7 billion.
This pattern continued into Q1 2026, the strongest quarter in the recent four-quarter window with revenue of KRW 484.0 billion, operating profit of KRW 49.6 billion, and net income of KRW 33.3 billion, before sharply moderating again in Q2 2026 to revenue of KRW 205.7 billion, operating profit of KRW 3.1 billion, and net income of just KRW 0.4 billion.
This reflects the industry characteristic that city gas and district energy demand concentrates in the winter season (Q4-Q1).
On the balance sheet side, the debt ratio declined steadily from 444.2% in 2022 to 407.3% in 2023, 339.8% in 2024, and 278.7% in 2025, while operating cash flow, after dipping to KRW 69.2 billion in 2023, recovered to KRW 104.5 billion in 2024 and KRW 124.0 billion in 2025, showing that the earnings improvement was accompanied by stronger cash generation.
