Revenue last year sank 17.39 percent to NT$589.2 million from NT$713.25 million in 2018 due to excess inventory in the supply chain, Ample said. The company generated 90 to 95 percent of its revenue from conductive paste used in passive components, it said. Factory utilization approached 100 percent last month, thanks to “robust inventory replenishment from customers,” Ample said. In addition, Ample has expanded its products to conductive paste for solar cells, it said. The company expects solar conductive paste to contribute about 10 percent of total revenue this year.
