The company also reported an increase in test cell utilization by 3 percentage points quarter-over-quarter, reaching 75%, and secured a $28 million design-win order for the mobile and automotive sectors. These factors, combined with the introduction of new products and expansion into new markets, appear to be driving the stock's after-hours surge.
