Even as gen-next successfully runs some of biggest names in Motown, this week the third generation of the Mammen family took over the reigns at tyre giant MRF. Rahul Mammen Mappillai, the eldest son of Chairman K M Mammen and Director Ambika Mammen, and grandson of the legendary K M Mammen Mappillai — took over as the new MD of the company. The tyre manufacturer is currently facing headwinds with margin pressure and rising raw material costs leading to a 32 per cent dip in Q4 net profit to Rs 286.77 crore. Current MD Arun Mammen, brother of KM Mammen, has been reappointed Vice Chairman and MD. The new MD has already had a nearly 14-year stint in various important roles in the company.
