Alteogen, the top market cap company on South Korea's secondary KOSDAQ market, has decided to move to the main KOSPI bourse to secure stable funding and enhance its corporate value. Shareholders approved the proposal on Monday, with the firm aiming for a listing next year.
Alteogen Inc., a biotech firm established in 2008, maintains a pipeline featuring next-generation biobetters. The company's market value reaches approximately 24.9 trillion won (about $17 billion), accounting for 5 percent of the KOSDAQ's total market capitalization. Upon moving to KOSPI, it could rank in the top 30 by market cap.
On Monday (December 8, 2025), shareholders approved the proposal to transfer to the KOSPI market. Following delisting from KOSDAQ, Alteogen plans to submit its KOSPI listing application and targets completion within the next year. This move aims to establish stable funding sources and elevate corporate value.
Meanwhile, EcoPro BM Co., the second-largest by market cap on KOSDAQ, is also pursuing a shift to the main bourse again. The South Korean cathode producer, with a market cap of about 16.5 trillion won representing 3.3 percent of KOSDAQ, had withdrawn its earlier plan in February. The announcement came from Alteogen's headquarters in Daejeon.
