Description of Material Information or Fact

:

Currently, the Company still uses a Core Banking System under a managed service model, and a number of issues have been identified.

Furthermore, as the scale of the business expands, service complexity increases, security demands rise, and the need for technological flexibility grows, the managed service model is beginning to show certain limitations. Therefore, the Company deems it necessary to transform its core banking system from a managed service model to an on-premise model.

The transformation of the core banking system from a managed service model to an on-premise infrastructure is a strategic move aimed at strengthening the institution's position in technology management, maintaining competitiveness, and building a foundation for the Company's long-term independence.

In order to enhance digital security and self-reliance, the Company plans to replace its core banking system and supporting systems with those provided by its affiliate, CCB Fintech.
