What specific operational change has PTTGC implemented at GCP's Rayong polyol factory, and what is its current status?

PTTGC has suspended operations at GCP's polyol production factory located in the Hemaraj Eastern Industrial Estate in Rayong Province, Thailand. The factory is now in a 'standby preservation' state—meaning it is not actively producing but remains fully capable of resuming operations at any time.

What was the ownership structure of GCP before and after PTTGC's restructuring, and what does the change signify?

Prior to the restructuring, PTTGC held 82.1% of GCP, while Japan's Sanyo Chemical Industries Co., Ltd. held 14.9% and Toyota Tsusho Corporation held 3%. As part of the restructuring, PTTGC increased its stake to 100%, achieving full ownership and eliminating minority shareholders—signifying complete strategic control over GCP and its assets, including the Rayong factory.
