# Yesiang expects revenue to rise amid strong demand

Yesiang Enterprise Co (鈺祥), the nation’s biggest semiconductor chemical filters supplier, on Monday said it aims to grow revenue by at least a double-digit percentage this year after tapping into a new market segment by supplying recyclable chemical filters.

The company said it is also benefiting from significant increases in consumption of airborne molecular contamination (AMC) prevention and chemical filters by major customers, due to high silicon purity requirements during the manufacturing process for advanced semiconductors such as 2-nanometer chips, the company said.

“AMC filter usage doubles when chipmakers introduce a new generation of technology. As chip manufacturing becomes increasingly complex, AMC control becomes increasingly critical,” Yesiang chairman James Chuang (莊士傑) said.

Yesiang, which commands about a 70 percent share of Taiwan’s AMC market, last year opened two new factories in Tainan’s Liouying District (柳營), as customer demand continued to grow, Chuang said, adding that the company has a long order visibility through 2030.

The company supplies AMC filters to more than 30 chip fabrication plants including 17 advanced fabs in Hsinchu, Taichung, Tainan, Kaohsiung and Arizona. It counts Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and ASE Technology Holding Co (日月光投控) among major customers.

Recyclable AMC filters are expected to make up about 25 percent to 30 percent of the company’s revenue this year, Yesiang spokesman Alex Tsai (蔡呈佑) said.

The company this year began to supply this new product on a subscription basis, he said.

The new filters can be recycled and reused 10 times, allowing chipmakers to reduce industrial waste by 95 percent and carbon emissions by 85 percent, he said.

The company is to debut on the Taipei Exchange’s Emerging Stock Board today at NT$602 per share. It plans to apply for a listing on the Taiwan Stock Exchange in the fourth quarter.

Yesiang reported that revenue last year dropped 13.5 percent to NT$1.66 billion (US$51.83 million) from NT$1.92 billion in 2024, citing delays in new product development.

Net profit plummeted 68.45 percent to NT$185 million from NT$589 million in the previous year. Earnings per share fell to NT$2.64 from NT$10.38, and gross margin shrank to 44 percent from 53 percent.
