Bangchak Finalizes BSRC Delisting and Prepares Newly Issued Shares of BCP for Trading on 12 December 2025 Advancing “One Team” with Shared Services to Strengthen Refinery and Marketing Operations

Mr. Chaiwat Kovavisarach, Group Chief Executive Officer and President of Bangchak Corporation Public Company Limited, stated that following the Company’s shareholding and management restructuring, Bangchak now holds 99.72% of Bangchak Sriracha Public Company Limited (BSRC) shares after the completion of the tender offer. The Company has completed the delisting of all BSRC shares, with the last trading day on 11 December 2025. Effective today, 12 December 2025, Bangchak’s newly issued ordinary shares have commenced trading on the Stock Exchange of Thailand.

This delisting of BSRC shares is expected to enhance competitiveness and operational efficiency in Bangchak Group’s refinery and marketing businesses, creating opportunities to leverage synergies under the “One Team” concept, which focuses on seamless and continuous operational integration between the two refineries. The restructuring will also improve service station management, workforce allocation, and cost efficiency, in line with the new management structure effective 1 January 2026, which consolidates the Refinery & Marketing operations of both companies and separates Oil Trading to enable a more specialized focus and higher growth potential.

Additionally, the Group continues to pursue operational excellence by eliminating redundancies and reducing costs through Shared Services, strengthening the Group’s overall competitiveness. The Company expects to realize cost savings of over THB 200 million annually, in addition to the EBITDA synergy of more than THB 5 billion already recognized in the first nine months of 2025.
