The European Commission has unconditionally approved Stonepeak Partners LP’s acquisition of a controlling stake in Castrol, clearing a key regulatory hurdle for BP Plc’s planned sale of the lubricant business and bringing the $10.1 billion transaction closer to completion.
The deal underscores growing investor interest in the global lubricants sector, a market valued at more than $160 billion annually and supported by demand from automotive, industrial, marine and commercial customers. While electric vehicles are expected to reduce demand growth for some engine oils over time, lubricants remain essential across manufacturing, transportation and heavy industry, making the sector attractive to long-term infrastructure and private-equity investors.
The Commission approved the transaction under its simplified merger procedure on June 15, according to its competition case register. The process is reserved for deals deemed unlikely to raise competition concerns and does not require remedies. The regulator has yet to publish its full decision.
The absence of conditions reflects the limited overlap between the parties. Stonepeak is an infrastructure-focused investment firm rather than a lubricant producer, reducing the likelihood of competition concerns that might otherwise have required divestments or operational commitments from Castrol.
Under the agreement announced in December 2025, New York-based Stonepeak will acquire a 65% controlling interest in Castrol at an enterprise value of approximately $10.1 billion. BP will retain a 35% minority stake through a newly created joint venture, while Canada Pension Plan Investment Board will invest up to $1.05 billion for an indirect holding. BP has said it expects net proceeds of about $6 billion, which will be used to reduce debt.
The European clearance follows an unconditional approval from China’s State Administration for Market Regulation. Reviews by the Australian Competition and Consumer Commission and the Competition Commission of India remain ongoing. Castrol, which supplies automotive, commercial and industrial lubricants in more than 150 countries through a network of around 20 blending plants and over 100 third-party facilities, is one of the largest lubricant brands globally. BP has said the disposal forms part of a broader divestment program targeting $20 billion by the end of 2027.
According to estimates from Grand View Research, Fortune Business Insights and other industry analysts, the global lubricants market generates annual revenues of more than $160 billion and is expected to continue growing, driven primarily by industrial and transportation demand.”
