Topco Scientific Hits Record High of NT$7.51 Billion in June, Driven by Surging Performance in Advanced Materials and Environmental Engineering

Strong Demand for Photoresist, Silicon Wafers, and Quartz Cloth; Newly Consolidated "Eastern Rainbow Green Energy" Targets the Zero-Waste Market

Topco Scientific Co., Ltd. (TWSE: 5434), a leading integrated service provider of critical semiconductor materials, announced June consolidated revenue of NT$7.51 billion, setting a new monthly record. Revenue increased by NT$970 million from May and grew 32.9% year over year. Cumulative revenue for the first half of the year reached NT$39.32 billion, representing a 20.2% increase from the same period last year.

Strong demand for AI chips has kept advanced process and advanced packaging capacity fully utilized, driving robust demand for semiconductor materials. Sales of key products-including photoresists, silicon wafers, quartz, FOUP, and slurry-all posted double-digit month-on-month growth. As AI computing continues to evolve, demand for high-speed transmission with low signal loss is increasing. Thanks to its excellent thermal stability and low dielectric properties, quartz cloth has become an essential material for AI server applications. Sales of quartz cloth recorded multiple-fold growth in June, highlighting Topco's ability to capitalize on the rapid expansion of AI infrastructure.

Beyond its growth in semiconductor materials, Topco also reached a new milestone in its environmental green energy business this quarter. Starting in June, "Eastern Rainbow Green Energy Environmental Technology Co., Ltd." was officially consolidated into the Topco Group. Eastern Rainbow Green Energy is a specialized contractor in industrial waste gas and liquid waste incineration, as well as air pollution control engineering, with a long-term focus on Taiwan's petrochemical and electronics industries. Notably, the company has a proven track record in constructing incinerators and waste gas treatment systems for a leading semiconductor manufacturer's organic solvent recovery project at the "Taichung Zero-Waste Manufacturing Center." Topco's first-half revenue set a historic high for the same period. Looking ahead to the second half of the year, the company will continue to deepen its position in advanced materials and environmental green energy, while working with overseas subsidiaries to accelerate its global expansion.
