Auto major Maruti Suzuki NSE 0.81 % on Wednesday reported a 65.35 per cent year-on-year (YoY) plunge in net profit at Rs 475.30 crore for the September quarter of FY22 compared with Rs 1,371.60 crore in the same quarter last fiscal. Adverse commodity prices and lower sales volume due to electronic component shortages (leading to lower capacity utilisation) hit the numbers, the automaker said in a BSE filing.
