Bangkok – 13 January 2026 – PTT Global Chemical Public Company Limited, or GC, summarized its performance in line with its strategy to strengthen the organization throughout 2025. This was driven by the implementation of a holistic optimization approach, alongside the application of innovation and digital technologies across all dimensions under the “3 Smarts” framework: Smart Plant, Smart Sales & Marketing, and Smart Work Process. These initiatives enhanced operational efficiency while strengthening GC’s financial position. As a result, GC successfully issued U.S. dollar–denominated subordinated perpetual debentures for the first time, totaling USD 1.1 billion, as well as a new tranche of Thai baht–denominated subordinated perpetual debentures with a total value of THB 10 billion. Both issuances received an overwhelmingly positive response from investors, reflecting strong confidence in GC’s financial standing and business capabilities.

Mr. Narongsak Jivakanant, Chief Executive Officer of GC, said that 2025 was a year in which the petrochemical industry and the global economy continued to face significant challenges. Throughout the year, GC executed its plans with discipline and consistency, demonstrating the Company’s strength in operational efficiency, financial position, and competitiveness. This success was driven by the commitment and collective efforts of all GC employees. Under the GC StandOut concept—creating sustainable differentiation—Innovation Culture serves as a key enabling mechanism, alongside the practical application of innovation and digital technologies and collaboration with partners across multiple sectors. These efforts support the long-term, sustainable growth of GC’s high-value, low-carbon businesses. Key operational initiatives include:

Strengthening Financial Resilience

• First-ever issuance of U.S. dollar–denominated subordinated perpetual debentures totaling USD 1.1 billion, marking the largest issuance of its kind in South and Southeast Asia. Investor demand exceeded the offering size by more than eight times, reflecting strong investor confidence in GC’s financial position and business direction. The proceeds support GC’s debt reduction plan and long-term sustainable growth.
• Issuance of a new series of Thai baht–denominated subordinated perpetual debentures with a total value of THB 10 billion, offered through a public offering. The issuance received an overwhelmingly positive response from investors, strengthening the Company’s long-term capital structure and supporting its growth strategy in high-value, low-carbon businesses.

Enhancing Competitiveness

GC enhanced its competitive capabilities through a Holistic Optimization approach, alongside the systematic application of innovation and digital technologies under the 3 Smarts framework, comprising:

1) Smart Plant – Enhancing Real-Time Production Efficiency

Additionally, in 2025, GC became the first chemical producer to sign an agreement to import ethane from the United States for use in Thailand, with deliveries expected to commence by 2029. This initiative strengthens long-term feedstock security and competitiveness while enhancing production flexibility, without requiring additional infrastructure investment or significant modifications to existing production systems. The move aligns with GC’s Holistic Optimization approach, which focuses on improving cost efficiency and feedstock security.

This initiative represents another strategic collaboration within the PTT Group. The project enhances energy efficiency and supports the adoption of clean technologies in production, with the potential to reduce carbon dioxide emissions by more than 60,000 tons per year. It underscores GC’s commitment to driving business growth in parallel with achieving its Net Zero target by 2050.
