The acquisition of Kanorial chemical division for 830 Cr looks very expensive to me. It is 4 times Mak cap of Kanoria Chemicals & 3.5 times ABCIL.
Aditya Birla Chemicals all time high profit was 62 Cr. It may take more than 10 years to re-pay this huge debt so it is definitely going to hurt business because of increasing interest cost.
