On a confirmed annual basis, revenue fell from KRW 28.7 billion in 2022 to KRW 26.6 billion in 2023, then rebounded to KRW 30.9 billion in 2024 and KRW 42.9 billion in 2025, the highest of the past four years.
Operating margin stayed stable in the 15.0%-16.0% range throughout 2022-2025, with operating profit rising steadily each year from KRW 4.30 billion in 2022 to KRW 6.54 billion in 2025.
Owners' net income, however, was uneven: profits of KRW 6.08 billion in 2022 and KRW 4.90 billion in 2023 were followed by a loss of KRW 0.40 billion in 2024 despite positive operating profit, before swinging back to a KRW 4.97 billion profit in 2025.
Non-controlling interests (KRW 0.84 billion) appeared on the balance sheet for the first time in 2025, a change linked to the expanded consolidation of subsidiary Korea Pile. The debt ratio rose gradually from 33.1% in 2022 to 43.6% in 2023 and 48.3% in 2024, before jumping sharply to 105.5% in 2025.
Quarterly figures show scale expanding markedly, from KRW 6.98 billion in revenue and KRW 1.39 billion in operating profit in Q2 2025 to KRW 15.34 billion in revenue, KRW 2.20 billion in operating profit, and KRW 1.34 billion in owners' net income in Q4 2025.
This growth continued into 2026, with Q1 revenue of KRW 16.56 billion, operating profit of KRW 2.68 billion, and net income of KRW 2.18 billion, followed by Q2 revenue of KRW 17.60 billion, operating profit of KRW 3.43 billion, and net income of KRW 1.68 billion.
Quarterly operating margins have ranged between roughly 14% and 20%, indicating consistent profitability. Overall, while revenue and operating profit have expanded steadily, historical data show that net income can swing on non-operating factors, as seen in the 2024 loss.
