- August revenue increased 30.71% year over year to NT$25.04 billion, marking the strongest August performance in four years.
- January–August revenue rose 14.66% year over year, indicating accelerating demand.
- The gain appears primarily company-specific; broader technology-market strength may provide additional support, but the revenue surge is the clearest catalyst.
