Yesiang expects foundry expansion to drive revenue growth in 2H26

Yesiang's revenue doubling isn't an anomaly—it's a direct consequence of the advanced-node foundry expansion wave. As TSMC and Samsung accelerate sub-2nm deployments, micro-contamination filters have become critical yield gatekeepers, forcing upstream upgrades in gas delivery purity and photoresist handling systems. Geopolitical pressures are driving Taiwan, China-based fabs to localize supply chains, granting domestic players like Yesiang a 'compliance premium.' However, stricter U.S.-EU export controls could spike raw material costs by over 15%. Competitors such as Entegris and Pall may counter by acquiring regional niche players to penetrate Asia-Pacific capacity hubs. Over the next 18 months, roughly 7% of global front-end equipment capex will shift toward contamination control subsystems. Unless Yesiang reduces its reliance on a single client—currently exceeding 60% of revenue—its growth trajectory faces sustainability risks.
