Carlyle Holds Preliminary Talks with UAE Investors Over Potential Purchase of Lukoil’s International Assets

Carlyle has engaged in early discussions with state-linked Abu Dhabi investors about taking minority stakes should its proposed acquisition of Lukoil’s overseas assets proceed. The preliminary agreement with Lukoil covers a broad portfolio - including Iraq oilfields and Eastern European refineries - but remains subject to U.S. regulatory approval, further due diligence and unresolved valuation.

Key Points

  • Carlyle has held exploratory discussions with Abu Dhabi investors Mubadala, XRG and IHC about taking stakes in a potential purchase of Lukoil’s international assets, including Iraqi oilfields and eastern European refineries - impacting the energy and private equity sectors.
  • The preliminary agreement between Carlyle and Lukoil excludes Kazakh assets and has no agreed valuation; one source put the package at around $20 billion, though that figure is unconfirmed - impacting asset valuation and M&A activity in energy markets.
  • Any transaction would require compliance with OFAC rules, completion of Carlyle’s due diligence and potential funds restrictions under U.S. jurisdiction, creating implications for banking, sanctions compliance and transaction execution.

Overview

U.S. private equity firm Carlyle has initiated exploratory talks with several investors in the United Arab Emirates about the possibility of bringing partners into a potential purchase of Lukoil’s international portfolio, three sources familiar with the matter said. The discussions follow a preliminary agreement announced between Carlyle and Lukoil that would transfer a wide-ranging set of overseas assets to the U.S. firm if it secures the necessary approvals.

Scope of the proposed transfer

The assets referenced in the initial agreement include oilfields in Iraq and refineries located in eastern Europe. The preliminary arrangement does not encompass Lukoil’s Kazakh holdings, and the parties have not settled on a final valuation, a separate source said. One source estimated the asset package at around $20 billion, though that figure has not been confirmed by the companies involved.

Potential UAE partners

The three sources identified state-controlled Abu Dhabi investors - Mubadala, XRG and IHC - as having held talks with Carlyle about taking stakes in the portfolio if Carlyle completes the transaction. At this stage no binding agreements have been reached. A separate source highlighted interest among the UAE parties specifically in Lukoil’s trading unit, Litasco.

Transaction mechanics and timing

It remains unclear when, or if, Carlyle would bring in outside partners should the purchase advance. One source said Carlyle plans to retain the portfolio intact. Industry practice for private equity energy transactions typically involves holding acquired assets for roughly five years before seeking to realize a return through a sale, a timeline noted by market participants but not specified as binding for this deal.

Regulatory and procedural constraints

Carlyle has indicated it still needs to complete due diligence on the Lukoil assets. Any deal would be structured to comply with the requirements of the Office of Foreign Assets Control (OFAC), the U.S. sanctions authority. OFAC guidance indicates proceeds from any sale of sanctioned assets must be placed in an account under U.S. jurisdiction and would remain frozen until any sanctions are lifted.

The U.S. Treasury has set a deadline of February 28 for Lukoil to divest its global portfolio, a timetable that has attracted interest from multiple potential bidders. Lukoil has said it remains engaged in discussions with other prospective buyers.

Public statements and responses

Requests for comment to Lukoil, Mubadala and XRG were not answered. Carlyle declined to comment on the reported discussions. IHC stated it would disclose any material developments in accordance with applicable market regulations and make announcements as required. Beyond those statements, there were no further public disclosures from the parties cited.


Note: This article reports only the information available from the involved parties and named sources. Timing, valuation and partner participation remain subject to confirmation and regulatory approvals.

Risks

  • Sanctions-related constraints: OFAC guidance requires sale proceeds to be held in a U.S. jurisdiction account and frozen until sanctions on Lukoil are lifted, creating execution risk for buyers and affecting banking and treasury operations.
  • Valuation and timing uncertainty: No agreed sale price has been disclosed and sources differ on valuation and partner involvement; this uncertainty affects deal certainty and valuation risk for private equity and energy investors.
  • Regulatory and due diligence hurdles: The transaction is contingent on Carlyle completing due diligence and securing U.S. regulatory approval, which could delay or prevent closing and influence market interest in the assets.
