BP has reached an agreement to sell a 65% shareholding in Castrol to Stonepeak, at an enterprise value of $10.1 billion.
The transaction marks a key milestone in bp’s efforts to accelerate its strategy, which involves portfolio simplification, strengthening the balance sheet, and concentrating downstream activities on its core integrated businesses.
The sale is part of bp’s previously announced $20 billion divestment programme and brings completed and announced divestment proceeds to date to around $11.0 billion. All proceeds from this transaction will be allocated to reducing net debt towards bp’s target of $14-18 billion by end 2027.
As of the end of 3Q 2025 bp’s net debt was $26.1 billion. Divestment proceeds guidance for 2025 is over $4 billion, of which $1.7 billion has been received as at 3Q25 results, with the remainder expected to be received by year-end 2025.
Carol Howle, interim CEO at bp, said: “Today’s announcement is a very good outcome for all stakeholders. We concluded a thorough strategic review of Castrol, that generated extensive interest and resulted in the sale of a majority interest to Stonepeak. The transaction allows us to realise value for our shareholders, generating significant proceeds while continuing to benefit from Castrol’s strong growth momentum. And with this, we have now completed or announced over half of our targeted $20bn divestment programme, with proceeds to significantly strengthen bp’s balance sheet. The sale marks an important milestone in the ongoing delivery of our reset strategy. We are reducing complexity, focusing the downstream on our leading integrated businesses, and accelerating delivery of our plan. And we are doing so with increasing intensity – with a continued focus on growing cash flow and returns, and delivering value for our shareholders.”
Anthony Borreca, Senior Managing Director and Co-Head of Energy at Stonepeak, said: “Lubricants are a mission-critical product, which are essential to the safe and efficient functioning of virtually every vehicle, machine, and industrial process in the world. Castrol’s 126-year heritage has created a leading market position, an iconic brand, and a portfolio of differentiated products that deliver meaningful value to its customers. We are excited to work alongside Castrol’s talented employees, coupled with bp’s continued guidance as a minority interest holder, as we support the business’s continued growth.”
BP’s shares opened 1.3% higher on Wednesday following the announcement.
The company’s share price is up around 9% so far this year, following a 15.7% drop in 2024.
