Taiwan Cement Announces Adjustment to Transaction Structure for Acquisition of CGH Equity

1. Date of Event: 115/07/09

2. Company Name: Taiwan Cement Corporation

3. Relationship with Company (Parent or Subsidiary): Parent Company

4. Cross-shareholding Ratio: Not applicable

5. Reason for Occurrence: Cimpor Global Holdings B.V. (hereinafter referred to as CGH) was originally a joint venture in which the Company, through its subsidiary TCC Dutch Holdings B.V., held a 40% stake, primarily serving as a holding platform for the Company and OYAK Capital's joint investments in the cement businesses in Turkey and Portugal. Subsequently, the Company completed the acquisition of control over Cimpor Portugal and Oyak Cimento, and the ownership of the related Turkish assets has been transferred to a newly established joint venture, TCC OYAK AMSTERDAM B.V. As a result, CGH no longer serves its original holding platform function.

6. Response Measures: To align with the Group's integration of European regional operations and future strategic planning for fundraising in European capital markets, the Company plans to restructure the equity framework of its European business cluster to integrate resources and streamline the Group's structure. Accordingly, the Company's 100%-owned European subsidiary will acquire the 60% stake in CGH held by the original joint venture partner, OYAK Capital. Upon completion of the transaction, CGH will become a wholly-owned subsidiary of the Company, with an estimated transaction consideration of approximately €64.7 million.

Subsequently, the Company will proceed with relevant equity and capital structure adjustments in accordance with the Group's overall planning to support the integration of European operations and continue optimizing resource allocation and capital efficiency.
