[1] | Following a partial loss in the first trial on February 14, 2025, approximately W 63,200 million was paid. An appeal has been filed and the case is currently pending in the second trial.
[2] | Subsequent to the end of the reporting period, a partial loss was decided in the first trial on February 5, 2026, and approximately W 41,500 million was paid. As of December 31, 2025 the Group has recognized litigation provisions of approximately W 40,100 million.
[3] | As of the end of the reporting period, there were five cases pending in the court of first instance (claim amount: W 169,930 million) and four cases pending in the court of second instance (claim amount: W 91,700 million). However, subsequent to the reporting period, all cases were concluded through withdrawal of the lawsuits following separate settlements with the plaintiffs.
[4] | These lawsuits are related to the trust business of Shinhan Asset Trust Co., Ltd. In the event of a loss, the judgment amount (principal and interest) will be paid from the trust account or can be recovered through a right of indemnity against trust-related parties. Accordingly, the impact on the Group’s own account is expected to be limited.
