Siam Cement Group

His Majesty King Maha Vajiralongkorn personally owns 33.64% of SCG, making the Thai monarch the single largest shareholder. The Crown Property Bureau, a separate entity historically linked to the Thai royal family, also maintains significant interests and acts as landlord for several SCG-related developments. This royal-patronage structure distinguishes SCG from purely institutional or public-market-owned conglomerates.

SCG Chemicals operates through long-dated joint ventures with global industrial partners, notably Dow Chemical and Mitsui Chemicals. The Long Son Petrochemicals Complex in Ba Rung-Vung Tau, Vietnam, represents the group's largest downstream petrochemical commitment. SCG tends to anchor these partnerships with operational control while sharing capital deployment with established chemical-industry players.

SCG has an explicit net-zero mandate across its cement and chemicals businesses and participates at the advanced level in the UN Global Compact. Cement production is shifting toward biomass and alternative fuels at the Saraburi plants, while the group holds membership in the Global Cement and Concrete Association's CEO-led net-zero concrete initiative. The group also holds legacy coal exposure which it has publicly committed to reducing.

The SCG Foundation operates distinct art and cultural programs, including the SCG Foundation Museum Collection in Bangkok and the Young Thai Artist Award program hosted at Bangkok Art and Culture Centre. The foundation functions as the group's philanthropic vehicle with a focus on Thai contemporary art and cultural heritage, structurally separate from SCG's industrial balance sheet.

The Crown Property Bureau holds a historical ownership stake and acts as landlord for many SCG-associated projects, including elements of the One Bangkok mixed-use development on Rama IV Road. While the Bureau's exact current equity position is not publicly detailed, its presence alongside the King's direct personal holding creates a layered royal-governance architecture that shapes SCG's strategic and investment decisions.

SCG's industrial footprint is anchored in Thailand's Saraburi Province for cement and building materials, with the chemicals division extending into Vietnam through the Long Son Petrochemicals Complex. The packaging business serves broader ASEAN consumer markets. The group emphasizes Thailand-plus-one manufacturing, with Vietnam representing its most significant overseas industrial capital deployment.

Yes — SCG participates in large-scale commercial real estate through the One Bangkok mixed-use development on Rama IV Road in central Bangkok. This project represents a direct real-asset capital allocation beyond the group's traditional industrial operating footprint, involving Crown Property Bureau land arrangements.
