Dividends

On July 26, 2024, we announced a value-up plan and set 2027 as the target year for achieving the following key targets:

According to the assessment results of the implementation of the value-up plan in 2025, we maintained a stable CET1 ratio exceeding 13%. Our ROE improved by 67 basis points year-on-year, reaching 9.11%, and our shareholder return ratio exceeded the targeted 50%, reaching 50.2%. We also reduced the number of our issued and outstanding shares by approximately 25 million by January 2026, demonstrating solid progress in implementing the plan.

We have now set new targets of the value-up plan and advanced its execution methodology, taking into account changes in the overall environment – early achievement of the original targets including the shareholder return ratio, the enactment of legislation on separate taxation of dividend income, and the trend of PBR improvement among domestic banking and financial holding companies. This new value-up plan is named as “Shinhan Value-Up +++ (Triple Plus).” Each year, we will set out our goals for the next three years based on an annual review of the appropriateness of our targets.

- New Targets: While maintaining the existing 2027 targets, we will provide updated guidance for the next three-year period annually. In addition, we will present and communicate principles for the allocation between growth and shareholder returns, as well as a formula for the shareholder return ratio.

To achieve the above goals, we will advance the execution methodology while focusing on the following strategic priorities:

With the restructuring of the value-up plan, we aim to enhance core profitability at a fast pace based on a stable CET1 ratio, while implementing more sustainable and predictable growth and shareholder return policies.

This value-up plan was adopted by resolution of the Board of Directors on April 23, 2026. We will continue to assess the progress of the implementation and communicate any updates or changes to this plan after deliberation and resolution by the Board of Directors.

For further details regarding the Company’s Corporate Value-up Plan, please refer to the voluntary disclosure titled ‘2026 Value-up Plan of Shinhan Financial Group Co., Ltd’ announced on April 23, 2026.
