Korea Petrochemical began a company-wide maintenance shutdown on October 13, 2026, with operations scheduled to resume by November 24, according to Webull. The interruption covers facilities tied to 84.49 percent of fiscal-year 2025 revenue, including KRW 2.83 trillion in segment revenue.

The market backdrop is mixed for Korea Petrochemical. The stock was last quoted at KRW 89,500 on the Korea Exchange on October 19, 2026 at 3:30 p.m. KST, while its 52-week range stood at KRW 76,700.00 to KRW 202,500.00. Its market capitalization was KRW 552.8 billion on that date.

Maintenance puts earnings under pressure

The latest reported quarter shows why the shutdown matters. In the second quarter of 2026, revenue reached KRW 956.0 billion, up 12.9 percent from KRW 847.0 billion in the first quarter, but the company posted a KRW 3.9 billion operating loss and a KRW 1.5 billion net loss, according to ATS View.

The maintenance period therefore comes after a quarter in which higher sales did not translate into operating profit. The duration also creates a clear timing issue for the third-quarter and fourth-quarter earnings outlook, because production is scheduled to restart only near the end of November.

What does the target imply?

Yuanta Securities Korea kept its KRW 180,000 price target and Buy rating on September 22, 2026, according to EDAILY. The target is higher than the October 19 market price, but the analyst also cited weaker second-half fundamentals and a production interruption lasting from October into November.

Three dates frame the stock

On September 11, 2026, a major-shareholder family member reported a stake change; on September 22, Yuanta retained its KRW 180,000 target; and on October 13, the maintenance shutdown began, as summarized by ATS View and Webull.

Upcoming reporting calendar

The next two dated milestones are the scheduled earnings report on October 30, 2026, identified by TradingView, and the planned maintenance completion on November 24, 2026, reported by Webull.

Stock stays below its target

Korea Petrochemical combines a KRW 180,000 analyst target with a KRW 89,500 market price and a production pause scheduled to last 42 days. The next earnings date should show how the shutdown affected the quarterly figures.
