Berkshire to Buy Occidental’s Chemical Unit for $9.7 Billion

Warren Buffett’s Berkshire Hathaway Inc. reached a deal to buy Occidental Petroleum Corp.’s petrochemical business for about $9.7 billion in cash.

The deal is the latest evidence that Buffett appears back on the hunt after years of refraining from large takeovers and progressively unwinding large holdings like his stake in Apple Inc.

The transaction is expected to close in the fourth quarter, Berkshire said Thursday in a statement. Shares of Occidental rose 1.4% in premarket trading in New York, while Berkshire’s Class B stock was down 0.3%.

OxyChem is set to be Berkshire’s largest acquisition since it took over the insurer Alleghany Corp. in 2022 for $13.7 billion, according to data compiled by Bloomberg. Buffett’s cash pile totaled $344 billion at the end of June, close to a record.
