On an annual basis, revenue expanded from KRW 9.211 trillion in 2022 to KRW 9.855 trillion in 2023, KRW 11.626 trillion in 2024 and KRW 17.495 trillion in 2025.
Operating profit slipped from KRW 718.7 billion in 2022 to KRW 639.9 billion in 2023 before recovering to KRW 1.175 trillion in 2024 and KRW 1.559 trillion in 2025, with operating margins of 7.8%, 6.5%, 10.1% and 8.9% respectively.
Net profit attributable to owners bottomed at KRW 226.0 billion in 2023, then rose to KRW 355.8 billion in 2024 and KRW 505.2 billion in 2025.
Quarterly, revenue and operating profit moved from KRW 4.595 trillion and KRW 429.5 billion in the second quarter of 2025 to KRW 3.466 trillion and KRW 426.8 billion in the third quarter and KRW 5.687 trillion and KRW 358.5 billion in the fourth, before jumping to KRW 9.483 trillion and KRW 641.3 billion in the first quarter of 2026 and KRW 16.185 trillion and KRW 817.8 billion in the second.
The second-quarter 2026 operating margin of roughly 5% was below the prior quarter's roughly 6.8%, largely a dilution effect as brokerage trading and valuation revenue is booked on a gross basis, so revenue growth far outpaced profit growth.
The driver of the profit surge is visible at the subsidiary level: Kiwoom Securities reported preliminary consolidated second-quarter 2026 operating profit of KRW 788.9 billion and net profit of KRW 680.6 billion, up 93.2% and 119.4% year on year, with equity commission income up 178.3% to KRW 451.9 billion as daily average trading value rose from KRW 10.8 trillion to KRW 36.3 trillion.
Operating cash flow was negative for four consecutive years at minus KRW 2.018 trillion in 2022, minus KRW 2.050 trillion in 2023, minus KRW 4.908 trillion in 2024 and minus KRW 6.534 trillion in 2025, reflecting the structural fact that growth in the securities subsidiary's financial assets and loan receivables is recorded within operating activities.
For the same reason, the debt-to-equity ratio of 861.0% in 2023, 808.2% in 2024 and 1,006.9% in 2025 cannot be compared on the same basis as a typical software company.
Over the four quarters from the third quarter of 2025 to the second quarter of 2026, net profit attributable to owners totaled KRW 748.8 billion, already above the full-year 2025 figure.
