KB Financial Group Inc. (KB) Income Statement

The 1.2% YoY growth in NII for 2026Q2 is a sharp deceleration from the 8.7% growth seen in 2026Q1, indicating that the benefits of rising rates are fading. The NIM of 0.4% is extremely low, likely reflecting a high proportion of non-interest-bearing assets or a distorted calculation, but it underscores the pressure on core lending spreads. Investors should monitor whether the Bank of Korea's pause in rate hikes will lead to further NIM compression, especially as deposit repricing lags.

The persistent 0.4% NIM across 2024Q1 through 2026Q2 is anomalous for a bank with KB's scale, suggesting that the reported NIM may be calculated on a different basis or that a significant portion of earning assets are in low-yield securities. This compares unfavorably to peers like Shinhan, which likely maintain higher spreads. The low NIM, combined with a 35.8% efficiency ratio in 2026Q2, implies that KB's profitability is increasingly reliant on non-interest income, which has been volatile.

The efficiency ratio in 2026Q2 is misleadingly low because total revenue was inflated by a massive negative non-interest income of -$20.8T, which is likely a data anomaly or a one-time charge. Excluding this, the underlying efficiency ratio appears stable around 25-27%, as seen in 2025Q1-Q3. However, the volatility in non-interest income, including a -179.8% fee percentage, suggests that KB's earnings are subject to significant swings from non-core activities, which may undermine the quality of its operating leverage.

The provision expense has been highly erratic, with a negative provision (i.e., a release) of $24.5T in 2026Q2, which is unusual and may indicate a reversal of prior charges or a data error. In contrast, 2025Q4 saw a provision of $11.1T, which weighed on operating income. This volatility suggests that KB's credit costs are not stable, and the market should be cautious about the sustainability of earnings. The rising delinquency rates in real estate PF loans, as noted in recent context, could lead to higher provisions in the future, warranting close monitoring.

The fee percentage of -179.8% in 2026Q2 is a red flag, as it suggests that non-interest income was not only negative but also overwhelmed total revenue. This is likely due to a large loss in the securities or insurance segments, possibly related to market volatility or ELS compensation. In contrast, fee income was a stable 20-24% of revenue in 2024-2025, indicating that the core fee-generating businesses are healthy. The recent volatility, however, highlights the risk that KB's earnings quality is compromised by non-recurring items, and investors should adjust for these when assessing underlying profitability.

The reported figures for 2026Q2 are internally inconsistent: total revenue of $11.6T cannot be reconciled with NII of $3.1T and non-interest income of -$20.8T, implying a large positive other income or a data error. This quarter should be treated with caution, as it may not reflect KB's ongoing earnings power. The EPS growth of 25.6% YoY is also misleading given the distorted revenue base. Analysts should focus on the more stable quarters of 2025Q1-Q3 to gauge the true trajectory, which shows modest NII growth and stable profitability.
