(Mr. Predee Daochai) Chairman For the long-term operational plan, we believe that our 3 Step Plus strategy is a step in the right direction but requires review, adjustment, and reprioritization to stay aligned with the current situation, taking into account the change in the industry landscape and making preparations for growth. Progress and achievements under the 3 Step Plus strategy are as follows: 1) Step Change: We enhance our competitiveness by reducing costs, optimizing operational efficiency through digital technology, adjusting production processes to enhance feedstock flexibility, expanding our customer base, and creating added value to our products. In 2023, we successfully restructured our logistics business under GC Logistics Solutions Co., Ltd. (GCL). By collaborating with WHA Venture Holding Company, GCL has bolstered its competitiveness in the logistics industry towards becoming an integrated logistics company with a comprehensive business network. 2) Step Out: We strive to foster growth in high-value and low-carbon businesses, which yield good returns, while also actively decarbonizing our three product groups. Specialty & Performance Chemicals: In 2023, our effort was focused on creating value and synergy with allnex across all dimensions. allnex was able to expand the coating business in Asia through the China Hub project and by co-establishing the Thailand Innovation Hub. In addition, Kuraray GC Advanced Materials Co., Ltd., commenced the commercial operation of its advanced engineering plastic production plant. Bio-based: We grew the PLA (polylactic acid) business through NatureWorks, which is currently constructing the second PLA plant at the Nakhon Sawan Biocomplex, Thailand’s first bio-hub. The new plant will help create jobs, generate income for farmers and workers in the area, as well as support the government’s policy. Circularity & Recycling: We scaled up the YOUTURN Platform nationwide to expand our integrated waste management and produced PCR through ENVICCO Co., Ltd. The high-quality food-grade PCR produced by ENVICCO has been certified by the US Food and Drug Administration (USFDA) and the European Food Safety Authority (EFSA) and is the first in Thailand to obtain certification from Thailand’s Food and Drug Administration. 3) Step Up: We seek to integrate sustainability into the foundation of our business operations and maintain our international leadership in sustainability, with the goal of achieving Net Zero Scope 1 and Scope 2 emissions by 2050 through clear action plans. In 2023, we exceeded our GHG reduction targets by optimizing efficiency and improving production processes, adopting energy-saving technologies, transitioning to renewable, low-carbon, or clean energy, and restructuring the portfolio towards high-value and low-carbon businesses to maintain profitability. Additionally, we undertook reforestation projects to offset carbon emissions through nature-based solutions and conducted research into Carbon Capture, Utilization, and Storage (CCUS) technologies. Thanks to our steadfast commitment to a sustainability-driven business approach that prioritizes an environmental, social, and economic balance alongside good corporate governance (ESG), GC has garnered recognition and various accolades both nationally and internationally, as detailed below. 31 PTT GLOBAL CHEMICAL PUBLIC COMPANY LIMITED Form 56-1 One Report 2023
