On confirmed figures, 2025 consolidated revenue was KRW 5,839.0 billion, operating profit KRW 1,005.6 billion and net profit attributable to owners KRW 770.0 billion, for a 17.2% operating margin.
That extended a run from 2022 revenue of KRW 3,163.3 billion and operating profit of KRW 147.5 billion (4.7%), through 2023 at KRW 3,587.4 billion and KRW 210.0 billion (5.9%), and 2024 at KRW 4,376.6 billion and KRW 456.6 billion (10.4%), meaning the margin roughly quadrupled in three years.
Cash generation improved as well, with 2025 operating cash flow of KRW 904.3 billion versus KRW 142.5 billion in 2024. In 2026, however, the margin direction reversed.
Quarterly revenue held up at KRW 1,417.6 billion in 2Q25, KRW 1,619.6 billion in 3Q25, KRW 1,625.6 billion in 4Q25, KRW 1,457.5 billion in 1Q26 and KRW 1,606.1 billion in 2Q26, but operating profit stalled at KRW 257.6 billion, KRW 277.7 billion, KRW 267.5 billion, KRW 224.2 billion and KRW 232.4 billion, taking the margin from 18.2% down to 14.5%.
Management attributed the 2Q26 outcome to product mix and a base effect from lower contingency costs than a year earlier; on a first-half basis revenue was KRW 3,063.5 billion, up 18.1% year on year, while operating profit of KRW 456.6 billion was down 0.8%.
By segment, the 2Q26 defense operating margin was 24.5% against roughly 1.0% for rail, where low-margin work booked about two years ago and extra costs from customer design changes are cited as the drag.
Net profit attributable to owners peaked at KRW 222.4 billion in 4Q25 before easing to KRW 201.4 billion in 1Q26 and KRW 185.3 billion in 2Q26.
On the balance sheet, the 2025 debt-to-equity ratio of 206.4% was lower than 218.2% in 2023, and the company said that its 1Q26 ratio of 188% falls to 54.7% excluding customer advances, with borrowings of KRW 109.5 billion against cash and equivalents of KRW 2,681.7 billion.
