AI servers drive order growth; Weltrend's fan motor driver IC visibility strong

Weltrend’s Q1 2026 outperformance signals a structural surge in demand for fan motor driver ICs driven by AI server thermal management. Technically, concurrent deployment of GPUs, ASICs, and CPUs accelerates high-density computing architectures, raising performance and integration thresholds for analog power drivers—pushing suppliers toward automotive-grade processes. Geopolitically, tightened U.S. export controls on advanced AI chips compel Taiwan, China-based firms to reconfigure supply chains, potentially increasing compliance costs by 15–20%. To counter Infineon and TI’s dominance in intelligent motor control, Weltrend must lock in ODM design wins now. While air-cooling remains dominant through 2027, offering a high-margin window, intensifying competition and cooling-tech transitions will likely compress margins thereafter.
