The country's biggest carmaker Hyundai Motor Co reported a lower-than-expected profits on Tuesday as the global chip crisis drove down vehicle shipments and said it will take a long time to get back to normal chip supplies. That comes just weeks after its global chief operating officer said the automaker aims to develop its own chips to reduce reliance on chipmakers. Separately, Samsung Electronics Co Ltd on Thursday said it expects component shortages to affect chip demand in the current quarter, even as it reported the highest quarterly profit in three years.
