1.5. Dividends

On October 24, 2024, KB Financial Group disclosed a detailed plan to enhance corporate value titled “KB Financial Group’s Sustainable Value-up Plan,” which includes information on shareholder returns and dividends. The key details of the plan are as outlined below (the full version of the plan can be accessed on KB Financial Group’s website at www.kbfg.com).

The Company’s goal is to maintain a target ROE of 10% or above, as it strives to improve profitability by enhancing its RoRWA, thereby strengthening its intrinsic corporate value.

The Company also seeks to maintain a target CET1 ratio of 13% or above. It aims to carefully manage its RWA growth rate by taking capital efficiency and profitability into consideration with the goal of maintaining a CET1 ratio in the range of mid-13% throughout the year.

The Company plans to execute its shareholder return policy in two phases. In the first phase, it will aim to utilize the capital in such amount that is equivalent to the amount exceeding 13% of its CET1 ratio as of the end of the previous year for the payment of shareholder returns in the following year. These returns will be supported through quarterly cash dividends (equitably distributed on a total annual basis) and through share buybacks and cancellations. In the second phase, the Company will aim to utilize the capital in such amount that is equivalent to the amount exceeding 13.5% of its CET1 ratio in the second half of the year to pay for additional shareholder returns. These returns, which will be made based on profits accumulated throughout the year, will be executed through share buybacks and cancellations.

These goals and expectations are subject to adjustments based on economic uncertainties, regulatory considerations, capital ratio projections, and the Company’s strategic objectives, including potential inorganic growth opportunities.

KB Financial Group’s progress report on its Sustainable Value-up Plan is available on its website (www.kbfg.com).
