What is the current progress and expected start-up timeline for SCG's LSP ethane project in Vietnam?

The LSP ethane project is over 50% complete, with the ethane tank at 54% completion and all contracts finalized; start-up is scheduled for the second half of 2027.

Why is SCG shutting down its Long Son Petrochemicals (LSP) plant in mid-May 2026, and what are the financial implications?

SCG is shutting down LSP in mid-May 2026 due to feedstock shortages caused by the Middle East conflict and to prepare for the ethane tie-in project; during the shutdown, LSP will incur fixed cash costs of approximately Bt 250 million ($7.6 million) per month, and restart timing remains 'pending market dynamics'.
