OCI has decided to discontinue its TDI (toluene diisocyanate) manufacturing and sales business, announcing the decision in a regulatory filing on the 29th.

The amount of business subject to suspension under this decision is 1,179,471,814,460 won (approximately 117.9 billion won), accounting for 5.87% of recent total revenue. Recent total revenue stood at 2,009,429,144,163 won, with both figures calculated based on the 2025 consolidated financial statements.

The reason for the business suspension is the 'closure of a marginal business.' OCI aims to improve profitability and enhance corporate and shareholder value through this move.

The scheduled date for the business suspension is December 18. However, the company explained that the suspension date may change depending on future progress.

The decision was made at a board of directors meeting on September 29, attended by all four independent directors.

OCI Holdings also filed a disclosure the same day regarding the major management matter concerning the suspension of its subsidiary OCI's TDI manufacturing and sales business.

Meanwhile, the Korea Exchange suspended trading in OCI shares from 10:58 a.m. to 11:28 a.m. that day, citing the disclosure of material information related to the business suspension. OCI stock futures were also subject to trading suspension and resumption measures during the same period (10:58 a.m. to 11:28 a.m.) in line with the suspension and subsequent lifting of trading in the underlying shares.
