Castrol India's July–September earnings slide 22.6% on input cost surge

what happened

Castrol India reported a 22.6% decline in net profit for July–September 2026, to ₹176.37 crore from ₹227.80 crore a year earlier, according to Moody's. Revenue went up 27.3% to ₹1,734.72 crore, but EBITDA fell 18.8% to ₹262.04 crore.

The main drag was input costs. Raw and packing material spending jumped 70.8% to ₹1,085.86 crore, pushing the EBITDA margin down from 23.7% to 15.1%. Management had flagged in August that commodity inflation would show up more clearly in September. For January–September, net profit still rose 8.6% to ₹766.25 crore.

Separately, BP is preparing to sell a 65% controlling interest in its global Castrol lubricants unit to Stonepeak, a deal valuing the business at about $10 billion. Stonepeak has proposed buying up to 26% of Castrol India at ₹194.04 per share, roughly ₹4,990 crore. Completion of the global transaction is targeted for the end of 2026.

why it matters

For markets, two issues stand out: margin pressure from costlier raw materials and a pending change of control. The transaction still needs regulatory approvals, and the open offer sets a price reference for Indian minority holders if it proceeds.
