Berkshire in talks for $10 billion deal for Occidental’s petrochemical unit, WSJ reports

Berkshire Hathaway is reportedly in talks to acquire Occidental Petroleum's OxyChem unit for approximately $10 billion, a move that would significantly aid Occidental in reducing its substantial $23.34 billion debt load, largely accumulated from its Anadarko and CrownRock acquisitions. This potential divestiture aligns with Occidental's ongoing strategy to address its financial leverage, while further deepening Berkshire's involvement as Occidental's largest existing shareholder.

Analysis

Berkshire Hathaway is reportedly in discussions to acquire Occidental Petroleum's OxyChem unit for approximately $10 billion, a transaction that directly addresses Occidental's primary strategic imperative: deleveraging. This potential divestiture would provide a significant cash infusion to help service a substantial debt load, which stood at $23.34 billion at the end of June following the major acquisitions of Anadarko Petroleum for $55 billion in 2019 and CrownRock for $12 billion last year. For Occidental, selling the petrochemical unit—which generated $2.42 billion in revenue in the first half of 2025—is a logical step in its ongoing asset sale program aimed at strengthening its balance sheet. For Berkshire Hathaway, already Occidental's largest shareholder, the deal would represent a deeper integration and the acquisition of a productive asset in a company it knows well, consistent with its strategy of purchasing businesses with strong fundamentals. The moderately positive market sentiment, particularly the 0.6 score for Occidental, underscores investor approval of this potential de-risking event.

Key Decisions for Investors

• Investors in Occidental Petroleum should view the potential $10 billion divestiture as a significant positive catalyst, as it would materially accelerate the reduction of its $23.34 billion debt load and likely lead to a re-rating of the stock.
• For Berkshire Hathaway shareholders, this deal represents a disciplined deployment of capital into a familiar entity, but its $10 billion size is incremental rather than transformative and should be seen as a continuation of its long-term value strategy.
• Traders should monitor for official confirmation of the sale and any subsequent guidance from Occidental's management regarding the updated pace of debt reduction and potential for enhanced shareholder returns.
