December 25, 2025 — BP’s biggest divestment in years is now reshaping more than just its balance sheet. It is also triggering a mandatory shareholder offer in India and pulling private-capital heavyweights deeper into the “hidden infrastructure” of the global economy: industrial lubricants.
BP has agreed to sell 65% of Castrol to Stonepeak in a transaction valuing the lubricants business at an enterprise value of about $10.1 billion, while CPP Investments (CPPIB) will invest up to $1.05 billion for an indirect, non-controlling stake. BP will retain 35% in a new joint venture, with the ability to sell that stake after a two-year lock-up. [1]
On December 25, fresh reporting and market commentary zeroed in on the next domino to fall: Castrol India. Under India’s takeover rules, Stonepeak and CPPIB are expected to launch an open offer to buy up to 26% of Castrol India at ₹194.04 per share, a modest premium to recent trading levels—prompting analysts to question how much the offer can lift the stock in the near term.

What’s new on December 25: the India tender offer and investor reaction
While the global Castrol transaction was announced late on December 24, several December 25 updates sharpened the picture:
- Indian investors: Reuters and Indian business outlets highlighted that the open offer price of ₹194.04 amounts to only a small premium to Castrol India’s latest close, suggesting limited upside purely from the offer mechanics. [3]
- Deal framing: Euronews argued the deal reflects a broader trend—private-capital firms treating legacy industrial brands like Castrol less as consumer products and more as “industrial infrastructure” embedded in everything from transport to data centres. [4]
- BP strategy narrative: December 25 coverage reiterated that Castrol’s sale is central to BP’s push to simplify and reduce debt—yet some analysts warned BP may be selling a stable, cash-generating asset that supported dividend quality. [5]
The headline deal: BP sells control of Castrol to Stonepeak
Under the agreement, BP will sell 65% of Castrol to Stonepeak. The transaction values Castrol at $10.1 billion enterprise value, which BP described as roughly 8.6x EV/LTM EBITDA. [6]
BP expects total net proceeds of about $6.0 billion, and says the proceeds will be used to reduce net debt. Those proceeds include around $0.8 billion tied to a pre-payment of future dividend income on BP’s retained 35% stake (plus other adjustments). [7]
A key nuance for investors: after the deal closes, BP says it expects to treat its remaining stake as an equity-accounted investment and does not expect to recognize earnings or receive a dividend in the short to medium term, noting Stonepeak has a preference on distributions. [8]
The deal is expected to complete by the end of 2026, subject to regulatory approvals. [9]
Why BP is selling: debt reduction and a “reset” strategy
BP is positioning the Castrol sale as a cornerstone of its broader divestment push. The company has repeatedly pointed to a plan to sell $20 billion of assets and cut net debt toward a $14–$18 billion target by end-2027—with net debt at $26.1 billion at the end of Q3 2025, according to BP’s statement. [10]
Market coverage on December 25 also emphasized the strategic context: BP has been trying to streamline operations and rebalance its approach after a period of underperformance versus rivals and a reassessment of the pace and shape of its renewable-energy ambitions. [11]
There is also leadership change in the backdrop. Reuters reported that BP recently appointed Meg O’Neill (currently CEO of Woodside Energy) as its next CEO, and noted Chair Albert Manifold told employees the company’s portfolio was “overly complex” and needed a faster refocus toward oil and gas. [12]
Why Stonepeak and CPPIB want Castrol: “mission-critical” cash flows
To understand why a firm known for infrastructure-style investments wants a century-old lubricants brand, it helps to look at what Castrol actually is today: a globally distributed industrial platform selling engine oils, industrial fluids, and greases into automotive, manufacturing, heavy industry, and energy systems across roughly 150 countries. [13]
Stonepeak describes Castrol’s products as “mission-critical”—a framing echoed across multiple statements and December 25 analysis. [14]
CPPIB’s rationale is similarly explicit. In its release, CPP Investments said Castrol is a “high-quality, global business” with a role in emerging applications “from electric vehicles to data centres,” aligning with its strategy of investing in businesses that are essential to the energy system and industrial economy. [15]
In other words: Castrol isn’t being pitched as a declining “oil-era” brand. It’s being pitched as a durable industrial enabler—one that can evolve with EV drivetrains, new thermal-management needs, and data-centre infrastructure growth. [16]
The India focus: Castrol India open offer and what it could mean
Why an open offer is happening
India’s takeover regulations can require an acquirer to make an open offer to public shareholders when control changes hands. Reuters reported that Stonepeak and CPPIB plan to launch an offer for up to 26% of Castrol India following the global transaction, potentially moving the new owners toward majority control depending on acceptance levels. [17]
Times of India summarized the current structure and the math: BP owns about 51% of Castrol India and public shareholders hold the remainder; an additional 26% purchase could take the new promoter group to 77%, which would then raise questions about meeting India’s minimum public shareholding requirements. [18]
The offer price: ₹194.04, and why the premium matters
The proposed open offer price is ₹194.04 per share. Reuters called it a 2.5% premium to the prior close, while Business Standard calculated it at roughly 2.3% above Wednesday’s close of ₹189.6. [19]
That narrow gap is exactly why December 25 commentary turned cautious. Business Standard reported that analysts see limited reason for a major rally if the offer price is only marginally above prevailing market levels, even if the ownership change is significant. [20]
Times of India also highlighted the implied outlay—about ₹4,990 crore if the offer were fully accepted—underscoring the scale of the India component inside a global deal that is otherwise framed in U.S. dollars. [21]
Longer-term questions: competition, EVs, and growth
Beyond the mechanics of tendering shares, Indian-market commentary is already shifting toward strategy. Business Standard noted concerns that Castrol India has faced intense competition over the last decade and that long-run lubricants demand could soften as EV adoption rises—factors that could shape how investors value the company under new ownership. [22]
That said, the global buyer narrative is that “lubricants” are not a single-product story anymore: modern fluids span industrial processes, specialized engineering applications, and fast-growing technology infrastructure—an argument reinforced by Euronews and CPPIB’s own statement. [23]
Valuation debate: is BP selling a “cash machine” too cheaply—or at the right moment?
The deal price has sparked a familiar argument in oil-and-gas boardrooms: should a major sell a steady, lower-capex, lower-volatility unit to fund debt reduction and simplify… or keep it as a stabilizer?
RBC analysts, cited in Reuters and repeated in December 25 coverage, questioned the logic of selling such a “cash generative” and low-capital-intensity asset—warning it could be detrimental to long-term dividend sustainability and earnings quality, even if accelerated dividend payments help BP reduce debt now. [24]
BP’s counter-case is clear in its statement: the sale accelerates the company’s reset, strengthens the balance sheet, and still preserves upside exposure via a retained 35% stake and future optionality to sell after the lock-up. [25]
What happens next: timelines and watch points into 2026
With closing targeted for end-2026, much of the near-term focus shifts from “deal announced” to “deal executed.” Key watch points include:
- Regulatory approvals across multiple jurisdictions (the global Castrol footprint includes minority interests in several countries, and the structure is expected to be implemented via a new joint venture). [26]
- The Castrol India open offer process, including how many shareholders tender and whether the new promoter group would need to reduce holdings later to comply with public float rules (if ownership rises above thresholds). [27]
- BP’s next divestments and whether proceeds continue to be directed primarily toward debt reduction as BP works toward its end-2027 net-debt target. [28]
- Castrol’s growth strategy under new control, especially around EV fluids, industrial specialties, and data-centre-related applications—areas repeatedly highlighted in December 25 analysis and partner statements. [29]
For readers tracking the energy transition from the sidelines, this story is a reminder that some of the most consequential moves are happening in “in-between” categories—businesses that touch oil, machines, factories, logistics, and data infrastructure all at once. And as of December 25, Castrol is becoming a test case for whether private capital can extract value from that industrial middle ground while BP attempts to rewire its own portfolio for the next decade.
