The cancellation of outstanding purchase orders is a direct negative impact on Cepton's short-term revenue prospects. While the company's plan to recover costs and continued collaboration with Koito and other OEMs may provide some mitigation, the immediate effect is likely negative for the stock price. The importance is high due to the significance of the ADAS program to Cepton's business, but not at the maximum because the company is still engaged with the OEM for future offerings. The confidence level reflects the clear negative impact but also acknowledges the potential for mitigating factors.
