OXY--
Occidental Petroleum, based in Houston, is known primarily for its oil-and-gas operations but has been under financial strain following its $10.8 billion acquisition of CrownRock LP last year. The company has been selling noncore assets to raise cash to pay down debt, having repaid $7.5 billion as of August [1].
Berkshire Hathaway, under the leadership of Warren Buffett, has been sitting on a massive cash pile. As of the end of June, Berkshire’s cash and Treasury bills totaled a record $344 billion, indicating a strong financial position to make such a large acquisition [1].
This deal would be Buffett’s second significant investment in the chemicals sector. In 2011, Berkshire acquired specialty-chemicals producer Lubrizol for nearly $10 billion, including debt [1]. Buffett, who is set to retire as CEO at the end of the year and hand over the reins to Greg Abel, has consistently stated that Berkshire prefers owning businesses over cash-equivalent assets [1].
The acquisition of OxyChem would further expand Berkshire’s portfolio and diversify its revenue streams. However, it remains to be seen how the integration will impact Occidental's overall financial health and Berkshire's future investment strategy.
