The stock was up 8.8% to $1.11 in post-market trading. Through Monday's close, shares had fallen 70% since the beginning of the year.

The maker of sensors and software used for safety and autonomous-driving features said the contract with the unnamed Japanese automaker supports its AI software capabilities.
