In 2025, the Company carried out volunteer projects through collaboration mechanisms with both public and private sectors as follows:

Urgent social assistance: Donated a total of 240,780 Baht to flood victims in critical areas.

Area-based disaster relief and recovery: Donated financial assistance to flood victims in Nan Province and Hat Yai District, and to those affected by the Thai-Cambodia border situation to help alleviate basic hardship and enable community members to resume normal life more rapidly (Community Resilience).

Restoration of educational opportunities: Provided budget support for the repair and restoration of Darunwittaya School, Nan City Municipality (Ban Suan Tan) damaged by floods to urgently restore the school to normal conditions, enabling students to return to the education system in time and reducing the risk of dropout due to economic and disaster impacts.

Engineering Learning Site Study Program : The Company aims to give youth an understanding of engineering work processes and career guidance now in its 11^th consecutive year. In 2025, 50 Mathayom 5–6 students from Nakhon Sawan School who are interested in engineering careers were brought to observe the Lopburi–Pak Nam Pho Double-Track Railway construction project. In prior years, 113 students who participated in the program subsequently gained admission to engineering faculties. The Company has also employed program graduates in engineer positions, helping create career stability for local youth and returning highly skilled labor to society, while addressing the Company’s long-term engineering personnel shortage.

Blood donation project — 34th consecutive year: More than 189 executives and employees across the Group companies representing 15% of total employees donated 85,050 cc (189 units) of blood to the Thai Red Cross Society. The Company organizes this activity every 3 months. The blood collected helps replenish the reserve blood bank and can be used in medical treatment and life-saving for more than 560 patients in emergency cases (averaging 3 lives saved per unit).

Ecosystem conservation and climate change mitigation: More than 100 executives and employees across the Group representing 8% of total employees jointly constructed 10 check dams and planted 100 trees at the Khao Krao area in collaboration with the Tha Khlo Sub-district Administrative Organization (SAO), Saraburi Province to slow water flow, increase topsoil moisture, and prevent riverbank erosion during the flood season, enhancing the surrounding ecosystem. The Company also collaborated with the Royal Thai Army Nature Study Center at Bang Pu, Samut Prakan Province, to plant 1,000 mangrove trees to strengthen the coastal ecosystem, filter pollution before it flows into the sea, serve as an important aquatic nursery for the community, and function as a highly efficient carbon sink (Blue Carbon). This project is estimated to sequester approximately 9.4–13.4 tCO₂e per year (based on a study on CO₂ sequestration by Rhizophora spp. in mangrove plantation areas in Thailand).
