Isu Specialty Chemical stock (ISIN KR7457190007) was trading at KRW 80,800 on KRX at 12:56 p.m. KST on October 7, 2026, down 4.04 percent from the previous close. The latest company-specific milestone is the October 6 Analyst Day, which focused on the Li2S commercial plant and the next phase of specialty-material production.

Quarterly figures improve

According to ATSview, Isu Specialty Chemical reported Q2 2026 revenue of KRW 108.0 billion, up 8.3 percent year over year. Operating profit reached KRW 7.7 billion, producing a 7.2 percent margin, while net income was KRW 3.6 billion.

The sequential comparison is also material: operating profit increased from KRW 3.5 billion in Q1 2026 to KRW 7.7 billion in Q2 2026, while revenue moved from KRW 109.0 billion to KRW 108.0 billion. That combination points to improved operating leverage rather than a volume-led revenue acceleration.

Li2S plant sets the next test

According to AWAKEPLUS, the October 6 Analyst Day covered the Li2S commercial plant, business conditions and investor questions. The event was scheduled in Ulsan for domestic analysts.

Korea Economic TV reported on September 29 that commercial production was planned for the fourth week of October. The plant is designed for initial annual output of 150 tons and expansion to 500 tons, while customer sample testing involves companies in Korea, China and Japan.

The near-term earnings effect is limited by the production schedule. The same report put projected 2026 Li2S sales at 20 tons and linked the larger financial opportunity to customer supply agreements after the plant moves beyond sample testing.

Stock remains below yearly high

At KRW 80,800 on October 7, 2026, the stock stood 38.7 percent below its 52-week high of KRW 131,800 and 82.0 percent above its 52-week low of KRW 44,400. The session range was KRW 79,700 to KRW 82,500, with volume of 141,035 shares.
