BP sells majority stake in Castrol to investment company Stonepeak

BP has reached an agreement to sell 65 per cent of Castrol to investment company Stonepeak for around $6 billion. The transaction values BP’s lubricants division at $10.1 billion.
With this sale, BP will retain a 35 per cent stake in Castrol through a newly formed joint venture and will thus remain involved in the further development of the brand, the company reported in a press release. Stonepeak will own the remaining 65 per cent. BP may sell the remaining stake after a two-year lock-in period.
The sale fits within BP’s $20 billion divestment programme. The proceeds, including $800 million in early dividend payments, will be used in full to reduce net debt to $14 billion to $18 billion by the end of 2027. At the end of the third quarter of 2025, that debt stood at $26.1 billion.
The Castrol sale is part of a broader change in direction, with BP refocusing on oil and gas. Last week, Meg O’Neill was appointed new ceo. She succeeds Murray Auchincloss and will be tasked with improving profitability and reducing costs. The sale of around 300 petrol stations in the Netherlands to Catom also fits within the divestment programme.
