On an annual basis, revenue rose from KRW 2,129.3bn in 2022 to KRW 2,602.1bn in 2023 and KRW 2,885.3bn in 2024, then fell to KRW 2,467.4bn in 2025.
Operating profit, by contrast, went from KRW 43.0bn in 2022 (2.0% margin) to KRW 82.6bn in 2023 (3.2%), KRW 225.7bn in 2024 (7.8%) and KRW 209.2bn in 2025 (8.5%), so the margin improved even as 2025 revenue shrank.
That points to a structure where the maintenance and replacement mix and pricing discipline matter more to margins than volume growth.
Net profit attributable to owners was KRW 78.4bn in 2022, KRW 318.9bn in 2023, KRW 183.2bn in 2024 and KRW 262.0bn in 2025, diverging from the operating trend in several years; 2023 in particular pared KRW 82.6bn of operating profit with KRW 318.9bn of net profit, an overwhelming non-operating contribution.
Operating cash flow expanded sharply from KRW 49.4bn in 2023 to KRW 256.4bn in 2024 and KRW 255.6bn in 2025, indicating better cash conversion of profits.
Quarterly, revenue and operating profit were KRW 637.5bn and KRW 55.5bn in Q2 2025, KRW 600.8bn and KRW 51.1bn in Q3, and KRW 634.7bn and KRW 54.3bn in Q4, holding a mid-8% margin, before Q1 2026 showed seasonal softness at KRW 545.8bn and KRW 40.5bn (7.4%).
Q2 2026 then delivered revenue of KRW 692.8bn, up about 8.7% year on year, and operating profit of KRW 84.5bn, up about 52%, for a 12.2% margin, the highest of the last five quarters.
However, net profit attributable to owners of KRW 161.9bn in that quarter was close to double operating profit, suggesting, as in Q3 2025 with KRW 147.1bn of net profit against KRW 51.1bn of operating profit, a large non-operating influence.
On the balance sheet, the debt-to-equity ratio fell from 166.2% in 2024 to 157.8% in 2025, with owners' equity of KRW 1,352.1bn and total liabilities of KRW 2,278.7bn at end-2025.
