The Group determines the operating segments by establishing strategic decisions. Chief operating decision maker (“CODM”) reviews operating profit by each segment in order to make decisions regarding the resources to be allocated to the segment and to evaluate the performance of the segment.

The reportable segments of the Group are in line with the organizational structure and CEO’s review of operations, and include mobile, online and others.

The accounting policies of the operating segments are the same as those described in the significant accounting policies.

The Group assesses the performance of its operating segments based on its operating profit or loss, which does not differ from operating profit reported on the consolidated statement of comprehensive income except for inter-segment transactions. Total assets and liabilities for each segment are not reported to CODM. The segment information for the years ended December 31, 2025, 2024 and 2023 are as follows.
