KB Financial reports strong 1Q 2026 revenue and profit growth.

KB Financial Group shows solid momentum in early 2026. Operating revenue of 30,698,923 million won grew 55.49% year over year, indicating significantly higher income from core activities compared with 1Q 2025.

Profit for the period rose to 1,916,469 million won, up 12.79%, while profit attributable to shareholders increased 11.50%. These gains are smaller than revenue growth, suggesting higher costs or credit expenses, but still represent meaningful bottom-line expansion versus last year’s first quarter.

The company emphasized that results are preliminary under K-IFRS and subject to auditor review. Subsequent disclosures for the 2026 fiscal year will clarify the drivers of revenue growth and how sustainable these margin levels are over future quarters.
