NC& said on Wednesday that it has recorded 33.58 billion won in revenue and 150 million won in operating income during the third quarter.
It marks the first time for the firm to post over 30 billion won in quarterly revenue. It also returned to profitability compared to a year ago.
NC& credited the performance to increase in black box sales, which increased despite the chip shortage that is reducing car production.
The company said it saw demand increase from Japan, a trend that started during the second half of 2020.
Profitability from black box sales however dropped due to price increases in components that go into them such as chip and liquid crystal display, NC& said.
Its subsidiary Nextchip also contributed to the growth, the firm said, as it saw sales of image signal processors increase during the quarter.
A contract development project also helped revenue of Nextchip, NC& said.
NC& said it expected sales of image signal processors to triple this year thanks to demand from Hyundai Motor.
