Because of slower customer orders and process optimization at its Southern Taiwan Science Park (STSP) facility, Greenfiltec’s consolidated revenue for the fourth quarter of 2025 was NT$17.5 billion (approx. US$552.5 million), down 11.75% from the third quarter. However, full-year 2025 consolidated revenue reached NT$63.5 billion, a significant 42.15% increase over 2024, driven by a rise in market share for AMC filters used in semiconductors.
