Phase-2 Spin-Off constitutes a further stage to consolidate a portion of the Wholesale Fiber Connectivity business, including related business, assets, liabilities, and business activities, into TIF in order to establish a more focused operating model, improve operational efficiency, enhance transparency in business management, and support long-term value creation for the Company and its shareholders;

Phase-2 Spin-Off is also a strategic measure in line with global trends in the telecommunications industry, where a number of telecommunications operators have established separate infrastructure entities (TIF) to enhance business focus, operational efficiency, business development flexibility, and company value optimization through more integrated management of infrastructure assets;
