Woori Financial Group said in a filing on Thursday it posted 3.14 trillion won in net profit for 2025, up 1.8 percent from a year earlier. The figure was close to its record 3.14 trillion won in 2022.

The company said the result was "effectively the biggest ever" when factoring in the full provisioning of a 51.5 billion won fine related to alleged collusion over loan-to-value (LTV) ratios.

Annual net interest income rose 1.6 percent to 9.03 trillion won, while non-interest income climbed 23.7 percent to 1.93 trillion won. Within non-interest income, fee income rose 3.6 percent to 2.16 trillion won.

The group's non-performing loan (NPL) ratio rose 0.06 percentage point from a year earlier to 0.63 percent. The bank's net interest margin (NIM) rose 0.02 percentage point to 1.46 percent, and the delinquency rate rose 0.04 percentage point to 0.34 percent.

Fourth-quarter net profit came to 345.3 billion won after reflecting one-off costs including loan-loss provisions.

Net operating profit rose 5 percent from a year earlier to 10.96 trillion won, setting a record. Interest income edged higher as the group's NIM improved by 3 basis points, supported by asset rebalancing and funding-cost efficiency despite two benchmark rate cuts.

Non-interest income jumped about 25 percent from a year earlier as fee income generated from its business portfolio following the completion of a comprehensive financial group and gains and losses related to securities, foreign exchange and insurance grew evenly.

The group's return on equity was 9.1 percent, similar to a year earlier. Selling and administrative expenses rose due to a base effect from voluntary retirement costs, acquisitions of insurers and investment in future growth including digital and IT, but the ratio of such costs was managed at around 45 percent through channel efficiency and cost controls across group companies.

By affiliate, Woori Bank's 2025 net profit fell 14.2 percent from a year earlier to 2.61 trillion won.

Woori Card's net profit rose 1.8 percent to 149.9 billion won, and Woori Financial Capital's net profit rose 5.1 percent to 148.7 billion won.

Woori Investment & Securities posted net profit of 27.4 billion won, up 996.0 percent from a year earlier. Tongyang Life earned 42.0 billion won in net profit in its first year after being acquired by Woori Financial Group.
