04 CORPORATE STRATEGY Future Development Plan

Future D evelopment P lan We plan to gradually shift the focus away from event planning and execution services and retain only certain categories of events for which we will continue to provide services, such as industry meetings and cultural performances. We plan to create cross - selling opportunities and foster synergic growth in our services. We plan to strengthen the internet media services and business planning and consulting services, by improving the quality of services, leveraging digital and technological innovations, and optimizing our business processes. We may expand into new markets, including but not limited to Malaysia, because Malaysia is geographically close to our Singapore headquarters, demonstrates similarities in user habits and preferences to our existing markets, and remains an overlooked market where the full market potential has yet to be explored. In order to remain competitive in the marketplace, we are committed to staying informed about market demands, securing skille d human resources, and continuously seeking ways to enhance service efficiency. In the medium to long term, we have outlined se ver al growth strategies. As of the date of this presentation, the operating entities have not made any plans to introduce new service types and have n ot entered into any agreements for the expansion into additional markets.
