On an annual basis, 2025 revenue of KRW 884.9bn was lower than 2024's KRW 942.2bn, but operating profit of KRW 121.0bn held up relatively well, and owners' net income jumped sharply from KRW 46.2bn to KRW 85.3bn.
In 2024, operating profit (KRW 123.6bn) was far larger than net income (KRW 46.2bn), while in 2025 the gap between operating profit (KRW 121.0bn) and net income (KRW 85.3bn) narrowed, suggesting a lesser drag from non-operating items or one-off tax effects.
The operating margin trended down from 16.2% in 2022 to 13.6% in 2023 and 13.1% in 2024, before recovering slightly to 13.7% in 2025.
Quarterly results show clear seasonality: Q3 2025 (July-September), the peak season, posted revenue of KRW 249.7bn and operating profit of KRW 53.2bn, lifting the operating margin to roughly 21%, while Q4 2025 (October-December), the off-season, saw revenue fall to KRW 196.6bn and operating profit to just KRW 9.0bn, pushing the margin below 5%.
Q1 2026 recovered to KRW 236.5bn in revenue and KRW 26.0bn in operating profit, and Q2 2026 posted revenue of KRW 204.7bn, operating profit of KRW 28.4bn, and owners' net income of KRW 20.9bn.
For H1 2026 as a whole, however, operating profit declined year-on-year, with the high-school segment—over half of total revenue—showing a double-digit percentage drop in operating profit, a clear sign of margin erosion.
This has been attributed to rising instructor fees, outsourcing costs, and advertising spend deployed to defend market share amid a shrinking pool of students.
