Castrol India Share Price Surges Over 6% as BP Agrees to Sell 65% Stake to Stonepeak

On December 24, 2025, Castrol India's share price experienced a significant surge of over 7% following the announcement that BP, a British energy major, has agreed to sell a 65% stake in its global Castrol lubricants business to the investment firm Stonepeak.  

The transaction is valued at an enterprise value of $10 billion. 

BP's Strategic Divestment 

BP's decision to sell a majority stake in Castrol is part of its broader strategy to streamline its portfolio and strengthen its balance sheet. The transaction is expected to generate net proceeds of approximately $6 billion for BP, which will be utilised to reduce its net debt.  

This move aligns with BP's ongoing efforts to simplify its operations and focus on its core integrated businesses. 

Details of the Transaction 

The agreement with Stonepeak values Castrol at an implied enterprise value to last 12 months EBITDA multiple of around 8.6x.  

This reflects the business's robust performance and growth potential. BP will retain a 35% stake in the new joint venture, allowing it to benefit from Castrol's growth while maintaining the option to realise further value in the future.
