Key points
- BP is in active negotiations with U.S. infrastructure investor Stonepeak to sell Castrol, the 125‑year‑old lubricants brand. [1]
- Bids were submitted in September; One Rock Capital Partners was also at the table earlier in the process. A deal is not guaranteed. [2]
- Market chatter pegs Castrol’s value near $8 billion, though estimates vary by source and currency. [3]
- The potential sale is central to BP’s plan to raise $20 billion from divestments by 2027 amid a strategic refocus on oil and gas and pressure from activist investor Elliott. [4]
- Trade press echoed the developments today, underscoring that Stonepeak remains in pole position. [5]
What’s new today
Industry outlet Offshore Engineer reported in the early hours of Thursday that BP’s talks with Stonepeak are ongoing and part of a portfolio overhaul designed to meet the company’s $20 billion asset‑sale target. The update reiterates Reuters’ exclusive from late Wednesday and keeps Stonepeak at the front of the queue. [6]
While neither BP nor Stonepeak has commented publicly, the cadence of coverage suggests the process is in a decisive phase. Reuters’ report adds that BP’s U.S. depositary receipts initially rose about 2% on the headline before easing—an indication investors see strategic merit but still await deal terms. [7]
Why BP is selling Castrol
The lubricants divestment is a cornerstone of CEO Murray Auchincloss’s commitment to streamline the portfolio and “do better for investors.” Under the plan, BP aims to generate $20 billion from sales by 2027 and has already flagged roughly $5 billion of completed or announced disposals for 2025. These moves arrive as BP shifts capital back toward conventional oil and gas after scaling down parts of its low‑carbon ambitions, and amid sustained pressure from activist shareholder Elliott. [8]
BP’s second‑quarter and third‑quarter updates this year telegraphed the same message: return focus, cost discipline, and asset rotation. The company raised its quarterly dividend to 8.32 cents in August and kept buybacks humming—steps meant to shore up shareholder support while it prunes the portfolio. [9]
How much is Castrol worth?
Valuations reported through 2025 have spanned a wide range. In recent weeks, RBC‑tracked market expectations circled about $8 billion. Earlier in the year, some outlets framed potential outcomes as high as $8–$10 billion, though bidders’ caution (and currency swings) make precise pricing fluid. For context, BP bought Burmah‑Castrol in 2000 for roughly £3 billion, and Castrol today is one of the world’s largest standalone lubricants businesses with a footprint in more than 150 countries. [10]
The buyer universe has narrowed over time. Reuters notes Stonepeak and One Rock submitted bids in September; it is unclear whether BP remains in talks with other parties. That deal uncertainty—and the possibility of structure tweaks—keeps final pricing an open question. [11]
Where Stonepeak fits
Stonepeak has about $80 billion under management and an acquisitive streak across energy and infrastructure. In May, a Stonepeak‑led consortium agreed to take a 65% stake in Phillips 66’s German and Austrian retail fuel business, illustrating its appetite for downstream and mobility assets. A Castrol acquisition would extend that thesis into a global lubricants brand with industrial and automotive channels. [12]
What Castrol brings to a buyer
Castrol is a highly recognized brand in engine oils, industrial lubricants and e‑fluids, with long‑running OEM partnerships and a resilient aftermarket. Reuters has previously described it as the third‑largest standalone lubricants business after Shell and ExxonMobil’s units, with broad geographic reach that could suit an infrastructure investor aiming for steady, cash‑generative returns. [13]
A buyer could also rationalize product lines, deepen distribution in growth markets, or push further into EV thermal management and data‑center cooling, where demand profiles differ from legacy motor oil. Those optionalities have been part of investor conversations all year, even as the core thesis remains cash yield and brand durability. [14]
Timeline check: from review to advanced talks
- February 2025: BP formally puts Castrol “under review” as part of a broader reset. [15]
- May 2025: Sale process kicks off; early valuations and bidder interest begin to surface. [16]
- September 2025: Bids submitted by Stonepeak and One Rock; process continues. [17]
- Nov 12–13, 2025: Reuters reports “active talks” with Stonepeak; industry outlets echo the update today. [18]
Market angle for today, Nov 13
Beyond deal headlines, BP’s stock is trading ex‑dividend today for ordinary shareholders in London (ADS ex‑date is Nov 14). The current quarterly distribution stands at 8.32 cents per ordinary share, payable on Dec 19, 2025—timing that can influence short‑term price action around the ex‑date. [19]
What to watch next
- Deal structure: Whether BP opts for an outright sale versus a partnership or staged exit could affect valuation and tax efficiency. [20]
- Regulatory scope: Castrol’s global footprint implies merger‑control reviews across multiple jurisdictions if a transaction is agreed. (General inference based on deal scope.)
- Portfolio signaling: A Castrol agreement would be BP’s clearest proof‑point yet that its reshaping plan is on schedule, following other disposals this year. [21]
Bottom line
As of November 13, 2025, BP’s Castrol sale is not done, but the center of gravity is plainly with Stonepeak. Price talk near $8 billion reflects current market expectations rather than a signed number. For BP, completing a Castrol transaction would both crystallize value from a prized consumer‑facing asset and validate its promise to accelerate disposals and refocus capital—two priorities investors have been pressing all year.
