Taesung's stock saw a notable rise in after-hours trading. On October 2, its shares closed at 29,400 KRW, up 2.08%, with a trading volume of 30,497 shares. While the KOSDAQ index has dropped by around 13% this year, Taesung's stock has surged fivefold, fueled by optimism surrounding its new ventures in composite copper foil and glass substrates.

Taesung, known for producing wet process equipment essential for printed circuit board (PCB) manufacturing, has been expanding its business into new areas. The company also supplies ceramic brushes used in PCB production and has reported significant financial growth. In the second quarter of this year, Taesung recorded consolidated sales of 14.5 billion KRW, a 79% year-on-year increase, and an operating profit of 2.7 billion KRW, a 2,286% surge compared to the same period last year.

Taesung has established itself as a leading player in the global market, providing turnkey automated solutions for critical pre-processing steps in PCB production. Its clientele includes major companies like Samsung Electro-Mechanics, LG Innotek, Daeduck Electronics, BH, and SimTech, with equipment supplied to the world’s top PCB manufacturer, Peng Ding, among others.

In addition to its stable core business, Taesung is gaining attention for its glass substrate division. According to company representatives, the development of glass substrate equipment is progressing, with the completion of key demo equipment expected in Q4. This is seen as a pivotal moment for the company's growth.

Industry experts are optimistic. Park Hee-cheol, a researcher at Heungkuk Securities, noted that Taesung’s expertise in PCB manufacturing will greatly benefit its glass substrate operations. He emphasized that the company's non-contact technology will improve production yield for fragile glass materials.

Another growth driver for Taesung is its composite copper foil plating equipment for secondary batteries. This massive piece of equipment, measuring 1.8 meters high, 4.6 meters wide, and 27 meters long, produces composite copper foil that is more durable and lighter than traditional options. The technology has attracted interest from Chinese battery manufacturers, and analysts believe it will play a significant role in enhancing battery safety, especially in light of recent lithium battery fire incidents.

Hyundai Motor Securities expects Taesung to achieve 148 billion KRW in sales next year, a 239% increase from this year's estimated 62 billion KRW, largely driven by its new ventures in the glass substrate and composite copper foil businesses.
